김유진 세종대학교 관광대학원 2018 국내석사

본 연구에서는 아무것도 처리하지 않은 비 처리군, 이물질을 제거 후 다시마로 넙치를 감싼 ‘다시마 전처리군’, 이물질 제거한 다시마를 식초로 전 처리한 후 넙치를 감싼 ‘식초로 전 처리 한 다시마군’의 세 가지 보관방법을 달리한 넙치육의 전처리를 통해 시간의 경과와 환경에 따른 수분, pH와 총균수, 아미노산 측정 등의 방법을 통하여 감칠맛과 texture를 증가시키는 숙성과정에서 어떠한 성분변화와 작용을 하는지에 대한 수치화된 자료를 도출하고자 하였다. 저장시간에 따른 수분 함량을 분석한 결과 비 처리군 넙치의 수분 함량은 저장시간이 질어질수록 수분 함량은 증가하여 저장시간 8시간에 가장 높게 나타냈다. 다시마 전 처리군과 식초로 전 처리한 다시마군은 수분 함량이 8시간에 가장 낮게 나타냈다. 저장시간에 따른 pH를 분석한 결과 비 처리군 넙치의 pH는 저장 초기에 6가장 낮게 나타났으며 저장시간 8시간에 가장 높게 나타났다. 다시마 전 처리군과 식초로 전 처리한 다시마군은 시간이 지날수록 pH는 증가하였다. 본 연구에서 식초로 전 처리한 다시마군이 다시마 전 처리군과 비 처리군인 일반적인 넙치 보다 pH가 높게 나타난 것은 생선회를 일반적으로 저장하면 효소류의 작용과 미생물의 번식으로 암모니아와 염기성 물질에 의하여 pH가 상승한 것으로 판단된다. 저장시간에 따른 적정산도를 분석한 결과 비 처리군 넙치의 적정산도는 저장시간이 지날수록 적정산도는 증가하여 저장시간 8시간에 가장 높게 나타났다. 다시마 전 처리군과 식초로 전 처리한 다시마군의 적정산도는 일반적인 비 처리군 넙치와 같은 경향으로 저장시간이 지날수록 적정산도는 증가하였다. 이는 다시마의 첨가로 변질로 인한 산도의 증가율이 낮아진다 는 것을 알 수 있으며 다시마의 첨가가 생선회의 저장성에 효과가 있을 것으로 사료된다. 저장시간에 따른 glutamic acid를 분석한 결과 비 처리군 넙치는 저장 4시간까지는 증가하였으나 이후 저장시간이 지날수록 감소하기 시작하였다. 다시마 전 처리군과 식초로 전 처리한 다시마군은 같은 경향으로 비 처리군과는 다른 경향으로 나타나 저장시간이 지날수록 증가하였다. 분석 결과 다시마 전 처리군과 식초 전처리 넙치의 glutamic acid 함량이 비 처리군보다 저장시간이 높게 나타난 것은 다시마의 glutamic acid 성분이 넙치 근육에 흡수되어 증가한 것으로 보이고 시간이 지나면서 근육자체에서 생성되거나 또는 식초처리의 유기산으로 인하여 육성분이 분해된 결과로 보여 지며 이결과는 넙치 생선회 맛에 감칠맛을 증가시킬 것으로 판단되었다. 저장시간에 따른 texture를 분석한 결과 비 처리군 넙치의 경도는 저장시간 8시간에 경도는 가장 낮게 나타났으며 다시마 전 처리군과 식초로 전 처리한 다시마군의 경도는 일반적인 비 처리군 넙치와 같은 경향으로 나타냈다. 비 처리군 넙치의 응집성은 저장 8시간에 증가하였으며, 다시마 전 처리군과 식초로 전 처리 다시마군의 응집성은 저장 8시간에 가장 높게 나타냈다. 비 처리군 넙치의 탄력성은 저장시간이 지날수록 감소하여 저장시간 8시간에 가장 낮게 나타났으며 다시마 전처리군의 탄력성은 비 처리군 넙치의 탄력성과 같은 경향으로 저장 8시간에 가장 낮게 나타났으며 식초로 전 처리한 다시마군의 탄력성은 저장시간이 지날수록 감소하는 결과를 나타냈다. 비 처리군 넙치의 점성은 저장시간이 지날수록 감소하여 저장시간 8시간에 가장 낮게 나타났다. 다시마 전 처리군과 식초로 전 처리한 다시마군의 점성은 같은 경향으로 저장시간이 지날수록 감소하였다. 비 처리군 넙치의 씹힘성은 저장시간 8시간에는 가장 낮게 나타났으며 다시마 전 처리군과 식초로 전 처리한 다시마군의 씹힘성은 같은 경향으로 저장시간이 지날수록 감소하였다. 넙치 생선회를 냉장 저장 시 저장시간이 지날수록 응집성, 경도, 씹힘성, 탄력성이 감소한 현상은 생선의 어종에 따라 콜라겐 및 근섬유의 용적 등 성질과 함량의 차이에 따라 근소하게 차이가 있는 것으로 사료된다. 저장시간에 따른 총균수를 분석한 결과 일반적인 넙치인 비 처리군의 총균수는 저장 2시간까지는 2.0×102CFU/g 수준에서는 검출되지 않았으며 저장 8시간에는 가장 높게 나타나 저장시간이 길어질수록 총균수는 증가하는 것으로 나타났다. 다시마 전처리군은 같은 조건일 때 2시간까지는 검출되지 않았으며 저장 8시간에 가장 높게 나타났다. 식초로 전 처리한 다시마군은 같은 조건일 때 저장 6시간까지는 검출되지 않았으며 저장 8시간에는 3.4×102 CFU/g로 나타났다. 이와 같은 결과는 산염처리 한 다시마가 총균수 증식을 억제 할 수 있는 것으로 판단되며 다시마의 알긴산 성분으로 인해 다시마로 감싼 넙치가 비 처리군인 일반적인 넙치회 보다 저장시간이 길어질수록 총균수는 적게 나타난 것으로 사료된다. 저장시간에 따른 관능적 품질 특성을 분석한 결과 비 처리군 넙치의 비린 냄새, 감칠맛, 전체적인 기호도는 저장 4시간에 질감과 뒷맛은 저장 2시간에 가장 높게 나타냈다. 다시마 전처리군의 비린 냄새와 감칠맛, 전체적인 기호도는 저장 6시간에 질감과 뒷맛은 저장 4시간에 가장 높게 나타냈다. 일반적인 넙치 보다 다시마로 처리한 넙치의 저장성 및 기호도가 2시간 연장 된 것으로 나타났다. 따라서 이화학적 품질특성, 미생물 특성과 관능적 품질 특성을 종합해 보면 일반적인 넙치 보다는 다시마 전 처리군과 식초로 전 처리한 다시마군이 생선회의 품질을 알 수 있는 수분함량과 pH가 적게 나타났으며 생선 회의 감칠맛인 glutamic acid와 texture에서 높게 나타났다. 또한 다시마로 처리한 넙치가 일반적인 넙치 보다 저장성이 우수한 것으로 나타났으며 관능검사에서도 비 처리군 보다 높은 기호도를 나타내 우리나라에서 인기 있는 생선회인 넙치회를 먹을 때 일반적인 넙치 보다는 다시마로 처리 하는 방법이 위생적이면서도 감칠맛과 texture를 높일 수 있는 방법으로 판단된다. In this study glutamic acid and texture were measured by moisture, pH, total viable counts, and glutamic acid measurement according to storage time through pretreatment of flounder with control, non-acid kelp and acid kelp. And elucidate the quantitative data on what kind of composition change and action in aging process. The moisture contents of the flounder of control increased with the storage time, and the moisture contents was the highest at 8 hours storage time. The moisture contents was the lowest in pretreatment of non-acid kelp and pretreatment of acid kelp at 8 hours storage time. The pH of the flounder of control according to the storage time was the lowest at the beginning of storage and the highest at 8 hours storage time. Pretreatment of non-acid kelp and pretreatment of acid kelp increased with storage time. In this study, the pH of the pretreatment of acid kelp was higher than the flounder of control and the pretreatment of non-acid kelp. It was considered that the pH of the raw fish was increased by ammonia and basic substances due to the action of enzymes and the growth of microorganisms. The analysis of the titratable acidity with storage time, the titratable acidity of flounder of control increased with storage time and the highest at 8 hours storage time. The titratable acidity of pretreatment of non-acid kelp and acid kelp were similar to those of normal flounder of control. The titratable acidity increased with storage time. This suggested that the addition of kelp decreased the rate of increase of acidity due to alteration. The addition of kelp may be effective for the storage stability of sashimi. The result of glutamic acid with storage time, The flounder of control increased until 4 hours storage time, but began to decrease with storage time. The amount of glutamic acid of the flounder at acid kelp and pretreatment of flounder at acid kelp increased with storage time as same tendency, and showed a significant difference to the flounder of control. The results showed that the glutamic acid content of the Pretreatment of non-acid kelp and acid kelp was higher than the flounder of control. It indicated that the glutamic acid content of kelp was increased by absorption into the flounder muscle. Over time, it was produced either in the muscle itself or as a result of the degradation of the muscle component due to the organic acids in the vinegar treatment. The results showed that the glutamic acid was increased in the flounder sashimi. The analysis of texture with storage time, the hardness of flounder of control was lowest at 8 hours storage time. The hardness of the texture according to the storage time was the same as that of the pretreatment of the non-acid kelp and the pretreatment of the flounder at acid kelp. The cohesiveness of acid kelp was highest at 8 hours storage time. Pretreatment of flounder at non-acid kelp showed the same springiness as flounder of control and the highest at 8 hours storage time. The elasticity of the flounder of control decreased with storage time and was the lowest at 8 hours storage time. The elasticity of pretreated group showed the same tendency as that of the flounder of control. It was the lowest at 8 hours storage time. The elasticity of the pretreatment of acid kelp decreased with storage time. The viscosity of flounder of control decreased with storage time and was lowest at 8 hours storage time. The viscosities of pretreatment of non acid kelp and acid kelp decreased with storage time with same tendency. The chewiness of flounder of control was lowest at 8 hours storage time. The chewiness of non-acid kelp and pretreatment of flounder at acid kelp decreased with storage time. It was considered that the decreasing phenomena of cohesiveness, hardness, chewiness and elasticity with storage time of flounder in cold storage depended on fish species and the content of collagen and muscle fiber. As a result of analysis of the total viable count according to the storage time, the total viable count in the flounder of control was not detected at 2.0×102CFU/g until 2 hours of storage and was highest at 8 hours storage time. As the storage time increased, the total viable count increased. The pretreatment of non-acid kelp was not detected until 2 hours at the same condition and showed the highest at 8 hours storage time. The pretreatment of acid kelp was not detected until 6 hours after storage at the same conditions and was 3.4×102 CFU/g at 8 hours storage time. These results suggested that the pretreatment of acid kelp can inhibit the growth of total viable count. It was considered that the total viable count of the kelp wrapped flounder was lower than of control due to alginic acid of kelp as the storage time longer. Sensory evaluation according to storage time showed that fishy odor, glutamic acid and overall-acceptability of flounder of control shwed high preference in 4 hours storage time and texture and after-swallowing taste were high in 2 hours storage time. In the 6 hours storage time, the fishy odor, glutamic acid, and overall-acceptability And at the 4 hours storage time, the texture and after-swallowing taste showed a high preference in the pretreatment with kelp. The preference of pretreatment of flounder at kelp was 2 hours longer than that of flounder of control. Therefore the physicochemical quality characteristics, microbiological characteristics, and sensory quality characteristics are compared with those of pretreatment of flounder and of control. In the moisture and pH value which are quality of sashimi, the pretreatment of non-acid kelp and acid kelp were lower than the flounder of control. And in the glutamic acid and texture, they were higher respectively. Pretreatment of flounder at kelp was more hygienic than that of flounder of control. It was more preferable in sensory evaluation than flounder of control. It was judged that pretreatment with kelp was hygienic rather than the common flounder, and it was a method to increase the texture and glutamic acid of the flounder, most popular sashimi in Korea.

제 7차 교육과정에 의한 음악교과서 비교 연구 : 7학년 감상영역을 중심으로

김유진 단국대학교 2006 국내석사

음악교육은 인간이 삶을 살아가면서 음악을 사랑하고 즐기며 음악의 심미적 체험을 통해 미적 가치에 대한 판단을 길러주고 정서적이고 창조적인 면을 형성해주는 매우 중요한 과정이다. 미적 가치의 발견은 감상을 통해 보다 효율적으로 이루어질 수 있기 때문에 감상교육은 음악교육에서 그 근본을 이루는 요소인 것이다. 이러한 감상교육은 현재 대부분 교과서를 중심으로 이루어지고 있다. 이 논문은 7차 교육과정에 의한 중학교 1학년 음악교과서의 감상곡을 비교 · 연구 하여 교육과정 개편에 따라 감상곡이 어떻게 변화하였는지 살펴보았다. 또한, 감상영역을 분석하여 7차 교육과정에서 제시한 내용에 충실하게 부합하는지와 그 외의 문제점들을 파악하여 앞으로의 음악 교과서 감상곡 선정에 있어서 하나의 기초 자료로 활용될 수 있도록 하는데 그 목적을 두었다. 분석에 앞서 교육과정 개정의 배경과 제 7차 음악과 교육과정의 중점사항을 살펴본 후 관련문헌을 통해 음악 감상교육의 중요성과 의의를 알아보았고 이러한 이론적 배경을 바탕으로 하여 감상곡을 분석하였는데 분석은 7차 교육과정에 의한 중학교 1학년 음악 교과서의 감상영역을 대상으로 감상영역이 차지하는 비율과 감상곡 내의 전통음악과 서양음악이 차지하는 비율, 감상곡 수록현황을 알아보았으며 감상곡을 시대별, 작곡가별, 장르별, 연주형태별로 나누어 각각의 비율과 그 내용을 분석하였다. 그 결과 7차 교육과정에 의한 음악 교과서에서는 전통음악의 비중이 증가하였고 그 외에도 보다 다양한 시대, 장르의 감상곡들이 제시되었으며 창작곡에 대한 관심이 높아졌다는 것을 알 수 있었다. 그러나 분석을 통해 7차 교육과정에 의한 음악교과서의 발전된 모습 외에 부분적인 문제점들을 파악 할 수 있었는데 그 내용은 다음과 같다. 첫째, 음악감상 영역 안에서 각각의 영역들이 차지하는 감상곡의 비율이 전체적으로 어느 한 영역으로 치우쳐 있었고 교과서별 차이 역시 현저히 나타났으며 둘째, 전통음악의 비중이 증가한 반면 그에 대한 심도 있는 자료나 부연 설명이 부족하였고 작곡가에 대한 정보가 실려 있지 않은 교과서도 있었다. 또한 감상곡 선정이 잘 알려진 곡들로 이루어져 다양하지 못하였고 감상곡과 연관된 정보들이 부족하였다. 그러므로 교사는 스스로 선정한 학습목표에 가장 적합한 교과서를 선택할 수 있어야 하고, 선택한 교과서로 수업을 진행해 나갈 때 그에 대한 많은 정보를 수집하고 다양한 자료들을 활용하여 보다 심미적인 감상교육이 이루어지도록 하여야할 것이다. 또한 음악감상 교육의 기본이 되는 교과서의 부족한 부분들을 개선함으로서 학교 현장에서의 음악교육이 더욱 조화롭고 균형 있게 이루어 질 수 있기를 기대한다. Music education is a very important process that enables us to love and enjoy music as we live our lives. It also helps us develops our sense of artistic value through the beauty of music and form the emotional and creative aspect in us. Discovery of the artistic value can be achieved more effectively through appreciation so the appreciation education is a fundamental element in music education. Such appreciation education is currently carried out in most of the textbook. In this paper, the music contents in the textbook of 1st grade of Middle School was comparatively analyzed in order to observe the changes, if any, according to the revision of the curriculum. Also, the appreciation part was analyzed to see if it satisfies the suggested contents specified in the 7th curriculum, and other areas were examined so that the paper can be used as one of the basic data that can be used to select music for the future music textbook. Before the analysis, the study looked into the background of curriculum revision and the pivotal points of the 7th music curriculum. Also, the study looked into importance and meaning of music appreciation education through relevant literary works and theories. The analysis was done with the appreciation of the music textbook for 1st grade of middle school. The study looked into the ratio of the music appreciation part in the textbook and the ratio of Korean traditional music and western music in the appreciation music as well as the list of the appreciation music. Also, the study categorized the appreciation music by time, composer, genre and performing style in order to analyze the ratio and the contents. The results show that the ratio of Korean traditional music has increased, music of different times and genres can be noticed and more stress is put on the creative music. However, other than the advanced parts of the music textbook of the 7th curriculum, the analyses showed partial problems of the textbook such as the followings . First, the ratio of each field of appreciation music generally showed an inclination to one field in the music appreciation field, and there were notable differences from one textbook to another. Second, the ratio of Korean traditional music was increased but on the other hand, there was insufficient in-depth information and expatiation for the music. There were some textbooks that did not even have information on the composers. Also, most of the appreciation music was well-known by people so the list was not diverse, and background information on the selected music was insufficient. Therefore, teachers should be able to select a textbook that is most suitable for their lesson plans, and they are advised to collect and apply various information for better aesthetic appreciation education. Also, they should improve the insufficient parts of the textbook that is the basic source of music appreciation education for harmonious and well-balanced music education.

우쿨렐레 교수·학습을 위한 유튜브 콘텐츠 활용방안

김유진 조선대학교 교육대학원 2021 국내석사

코로나 팬데믹 시대, 비대면·원격수업의 도구로서 ‘유튜브’는 다양한 유형의 교육 콘텐츠를 이용할 수 있는 플랫폼이다. ‘유튜브’의 콘텐츠를 활용하면 수업에 대한 학생들의 흥미를 유발할 수 있기 때문에 효과적인 교수·학습을 위한 플랫폼으로서의 가능성이 커지고 있다. 이러한 대내외적 환경과 교육적 필요성을 고려하여, 본 연구는 중등학교 음악 수업에서 우쿨렐레 교수·학습을 위한 ‘유튜브(YouTube) 콘텐츠’의 교육적 활용방안을 제시하는 데 있다. The purpose of this study is to suggest the ways to use the YouTube contents easily accessible for Ukulele instruction and learning for the middle and high school students. The results of this study can be summarized as follows. First, as a result of analyzing the music textbooks of middle and high schools amended in 2015, it was found that 25 pieces for Ukulele were carried on the 20 textbooks. Among them, the proportion of the 'popular songs' was highest. Secondly, as a result of the FGI, it was found that teachers were using the educational contents of the YouTube to help increase learners' interests. They also were referring to the YouTube Ukulele contents to enhance their instruction competence. Lastly, As a result of analyzing the Ukulele YouTube contents, it was possible to classify the Ukulele YouTube contents into performance contents and educational ones. Thus, it was possible to find the ways to use them pedagogically. This study suggests the following reform measures. First, in order to surmount the limit of the piece trend of the 2015 amendment of middle and high school textbooks, it is necessary to refer to the trend pieces in current carried in the YouTube contents in relation to instruction and learning of Ukulele. Secondly, in order to surmount the differences of the levels among students, it is deemed necessary to introduce the 'novice level' and 'advanced level' of contents to meet students' diversified needs. Thirdly, it is also necessary to produce the students' performance video in short length to be uploaded onto the YouTube. Then, the students can share the video contents that can lead the further discussion with other users. Fourthly, it is expected that such video data could be reorganized to be used for another educational or significant purposes. It is also expected that the students can practice the musical instruments outside of school, bringing up their self-initiated learning competence. Lastly, it is expected that this study would be followed up by future studies that would verify the effects of the YouTube Ukulele contents and identify their problems for the students' self-initiated learning.

보 탄력 개방에 따른 지하수 이용장해 평가 : 부정류 모델 분석 사례

김유진 국립공주대학교 대학원 2024 국내석사

2022년에 새 정부가 들어서면서 4대강 보에 대한 정부 정책이 녹조기인 하절기에는 개방하여 수질 악화를 완화하고, 그 외의 기간에는 연중 보 관리수위를 유지하여 보에 저장된 수자원을 최대한 활용하는 탄력 개방의 방식으로 변화하였다. 보 탄력 개방 정책에서도 여전히 지하수 이용장해에 대한 검토가 필요하다. 따라서 본 연구에서는 바뀐 환경정책에 따라 지하수 이용장해를 최소화하는 하절기(6월-10월) 동안의 적정 개방 수위를 평가하였다. 지하수 흐름 모델을 통해, 칠곡보의 관리수위인 25.5 m에서 최저수위인 15.2 m까지 단계별로 보 수위를 조절하는 모델 시나리오를 예측하여 시나리오별 지하수 이용장해를 평가 및 분석하였다. 그 후, 최종적으로 하절기에만 보를 개방하는 탄력 개방 시나리오를 통해 적정 탄력 개방 수위를 예측하고 분석하였다. 본 연구에서는 두 가지 평가 지표인 지상펌프 제약수위와 대수층 산출성 저하를 활용하여 지하수 이용장해 발생 여부를 평가하였다. 하천수위 변동 시나리오에서는 하천수위가 낮아질수록 지하수 이용장해 우려관정이 점점 증가하며, 15.2 m까지 개방하였을 경우(S11), 전체관정 543공 중 238개의 관정 우려관정으로 나타났다. 이는 관리수위인 25.5 m로 유지하는 사나리오(S1)에 비해 216공이 증가한 결과이다. 탄력 개방 시나리오에서도 마찬가지로 하절기 개방 수위가 낮아질수록 지하수 이용장해 우려관정이 증가하였다. 하절기 개방 수위를 25 m로 설정하는 경우(S12a), 우려관정이 2공이 나타난 반면, 하절기 개방 수위를 22 m로 설정하였을 때(S12d), 34공의 우려관정이 나타났다. 그럼에도 불구하고, 탄력 개방 시나리오의 우려관정의 수가 하천수위 변동 시나리오에 비해 적게 나타났음을 알 수 있다. 이는 지하수 이용량이 많은 동절기에는 관리수위를 유지하고 지하수 이용량이 적은 하절기엔 개방하는 것이 지하수 이용장해 우려관정의 수를 줄이는 것에 효과가 있다는 것을 나타낸다. In 2022, with the advent of a new government, the policy regarding the Four Major Rivers shifted. During the green algae season, characterized by high rainfall in the summer, the rivers were opened to alleviate water quality deterioration. In other periods, a seasonal opening strategy was adopted, maintaining regulated water levels throughout the year to maximize the utilization of stored water resources in the rivers. Even with the seasonal weir opening policies, there is a continued need to assess potential groundwater usage disruptions. This study evaluates the optimal opening levels during the green algae season (June-October) to minimize groundwater usage disruptions under the changed environmental policy. Using a groundwater flow model, various scenarios were predicted by adjusting the river water levels step by step from the management level of 25.5 meters to 15.2 meters. The scenarios were then analyzed to assess and analyze groundwater usage decrease. Finally, the study predicts and analyzes the optimal seasonal opening levels through a scenario that opens the dam only during the green algae season. Two evaluation indicators, the surface pump constraint level and the decline in confined aquifer yield, were used to assess the occurrence of groundwater usage decrease. In scenarios with river water level fluctuations, as the river water level decreases, concerns about groundwater usage disruptions increase. For example, in the scenario where the weir is opened up to 15.2 meters (S11), there were 238 concerned aquifer disruptions out of the total 543 wells, an increase of 210 wells compared to the scenario where the management level was maintained at 25.5 meters (S1). Similarly, in seasonal opening scenarios, concerns about groundwater usage disruptions increased as the green algae season opening level decreased. When the green algae season opening level was set at 25 meters (S12a), only 2 disruptions were observed, while at 22 meters (S12d), 34 disruptions were recorded. Nevertheless, the number of disruptions in the seasonal opening scenario was lower compared to the river water level fluctuation scenarios. This suggests that maintaining the management level during the dry season when groundwater usage is high and opening the weir during the green algae season when groundwater usage is low is effective in reducing the number of concerns about groundwater usage decrease.

The development status of national transport and logistic system is one of the key factors to decide its international competitiveness. With the increasing development of information and communication technology, the integration of transport & logistic system with informations of commodities, wholesale trade & financial transactions would be possible, and this expectation fortifies the economic importance of effective logistic system. The west coast area of Korea could confront an opportunity of iridescent development thanks to the surge of northeast economic region and the Korea-China FTA signed on June 1st, 2015, so called "an advent of the age of the west coast of the Korean peninsula" This study performs a fundamental research to find the major ports of the west coast for the suitable development strategy based on the Korea-China FTA, and the necessity of integrated logistic system is derived for those ports with analysis of the present status and problems of maritime logistic flow between Korea and China. Besides, a programing model is designed to investigate quantitatively the location and scale of the integrated logistic terminals, i.e., the major ports. As a mathematical programming technique, the mixed integer programming method is applied to investigate locations of important west coast's ports (WCPs) which could lead to a maximum reduction of transportation costs with minimized port facility investments. The findings of the analysis are as follows: ① The role of WCPs in terms of China cargo handling will be increasing while the role of the Busan Port is expect to be relatively decreasing. This is because those WCPs are located closely both to the major inland demand area and to the east coast of China and therefore, because they could take a comparative advantage with respect to the transport-distance. ② The cargo handling of Incheon Port is found to be increased outstandingly since the port-related infrastructure of the Incheon is relatively well equipped with the large volume of cargo-flows in/out of China at present. The port capacity of Incheon is needed to be expanded up to 108.5% of the present capability. Besides, the necessity of remodeling and upgrading of the Incheon Port targeting integrated logistic hub of the metropolitan area is urgently required, and the strategic planning of such remodeling would be suggested according to the trade progress between Korea and China. For the enhancement of Incheon Port's competitiveness, the direct underground rail-connection is highly recommended between the Incheon Port and inland container depot located at Euiwang City. The direct container loading system from the cargo vessel to train/truck is also recommended for the Incheon Port competitiveness. ③ The Ports of Pyungtaek and Kunsan Cities are pointed as the new candidates for another major ports together with the Incheon Port handling cargos of the Yellow-Sea region. The Pyungtaek Port is expected to grow as the second largest port of the west coast area, and the rate of required facility expansion of the Port was calculated as 135.9% of the present capacity. The cargo handling rate of the Kunsan Port would be increased up to the capacity limit of the Port, however the expansion of the Kunsan Port is not necessarily required. The Kunsan Port should also be remodeled and equipped towards so called integrated port logistic Depot together with the Pyungtaek Port. Besides, the development strategy of Kunsan Port should consider the future construction plan of the Saemankum Port so that the new born Kunsan-Saemankum Port could successively and economically function as a competitive major port of the west coast area. The planned capacity of the international scale Kunsan-Saemankum Port will be 28 births combining 8 births of Kunsan and 20 birth of Saemankum in 2020. However, those facility expansion should follow the stepwise process according to its role-increase based on trade volume between the two countries regardless of the target year. The future candidates as the major ports of west coast area should be upgraded toward the integrated logistic depot in themselves such that those ports are efficiently and economically connected with other inland freight depots through hub & spoke transporting system. The inland cargo transport system should also be switched from truck-oriented system to rail-oriented one. The governmen's policy should also focus on remodelling domestic ports toward integrated logistic space even above the international standard in order that the WCPs could successfully perform as the logistic maritime hub of the northeast economic region including Korea, China and Japan.

ABSTRACT A Study on the Sustainable Development Strategy of West Coast's Port Logistic System based on Korea-China FTA Kim, Yu-Jin Advisor: Prof. Kim, Seog-Min, Ph.D. Department of FTA Business Graduate School of Chosun University Formulation of Korea's passenger/physical distribution Hub (HUB) that utilizes the geopolitical advantages of the Korean peninsula that connects Japan with the Northeast Asia Region that has emerged in one of the world's three largest is one of the very important issues for the future advancement of Korea economy. This thesis will quantitatively analyze the location selection and development capability of the west coast port candidates in order that the west coast region could take the role as a core logistics point in Northeast Asia. In addition, it is the main purpose of this study to establish the sustainable development direction of the West Coast port logistics system after the Korea-China FTA. The sustainability of Port development is a very important policy consideration. This is because Port development requires a long-term period of 20-30 years, and it is difficult to correct the on-going developments in a short time depending on the situation changes. Therefore, it is the biggest contribution of this study to systematically analyze the comprehensive and sustainable port development strategy of the korea's west coast ports considering the evolution of the Korean logistic system and the possibility of the formation of a new transportation network in the medium to long term, while suggesting the reduction of the management functions of Busan port. Through the analysis of mixed integer programming method, which is one of the mathematical programming techniques, The meaningful number, locations and development scales of an optimal shipping base (i.e. port) are pointed in this study. In this thesis, targeting the year 2030, the quantitative analysis of the direction of the development of the West Coast Ports was first conducted, taking into consideration of the transportation cost and the port cost reflecting the area. Besides, we looked at the direction changes of the efficient port development under the new transportation network system - such as the construction of the Korea-China Railway Tunnel under the seabed - in terms of transport cost and freight's time value. As a result of comparing the above two analysis, it was found that the comprehensive development strategy of the West Coast Ports presented in this study has the possibility of sustainability even considering the future transport system. This was confirmed through the three serialized papers included in this study, and the three serialized papers applied the same model for analytical consistency. The originality and the discrimination of the study are as follows. First, this is not the mutually exclusive individual port development plan based on self demand analysis, but the first study that quantitatively presents the port's comprehensive optimum position and development capacity through mixed integer model analysis from the point of Korea-China FTA. Second, this thesis proposed a medium- and long-term sustainable West Coast Port development strategy, taking into account future changes in transportation conditions, such as the improvement of logistics conditions, the increase in port expansion costs, and the construction of the Korea-China submarine tunnel railway. In this study, the significance of the research is to measure and present the long-term west coast port development strategy that takes into account the increase in logistic flow between Korea & China, land transportation costs, and port expansion costs. It is expected that this result can be used effectively in consideration of cost factors such as the port opening time in the future. The more the Korea-China FTA mature and the trade volume between Korea-China, the more important it is that Incheon Port's transportation hub strategy needs to be prioritized. It was shown that Pyungtac-Dangjin Port and Gunsan Port (Semangeum Gunsan Port) could also be selected as additional potential base port candidates, and it was analyzed that long-term port planning formulation was necessary for those ports. In order to make Incheon Port a major logistic base, it is necessary to develop port logistics facilities suitable as a comprehensive logistics base directly connected to the inland cargo depot. For this reason, a direct cargo handling system should be established with a construction of underground cargo railway connecting the Incheon port-front (i.e. birth ) and Euiwang inland cargo base. It was confirmed that the China-freight(both in/out) of the capital region such as Seoul, Incheon and Gyeonggi-Do was prioritized to Incheon and Pyungtac port due to the relative difference in port expansion cost and transporting cost. As a result, it became also clear that the need to an additional port expansion of the Pyungtac port grows with respect to the realestate price increase of the Incheon port. In addition, if the land cost of the Pyung port increases, the freight in the Chungbuk-Do area will be additionally moved from the Pyungtac port to the Kunsan port. In this case, there is a need for another expansion of the Kunsan port (i.e. Saemangum-Kunsan Port). With a future realization of Korea-China Seabed Tunnel railway, it was confirmed that about 7% of import/export sea-cargo was likely to be converted to the Seabed Railway. And it is analysed that those converted cargos could be ones with a higher transporting-time value. Besides, other general containerized cargoes were analyzed as cost-effective to be transported under the existing port transportation system. As a conclusion, it is predicted that even under the new future transportation network system, the basic concept of the development of the West Coast Ports is not expected to be changed, and hence the sustainablility of the port's development strategy of the West Coast presented by this thesis has been confirmed.
