자료포락분석모형은 다수의 산출을 생성하기 위해 다수의 투입을 사용하는 생산시스템의 상대적 효율성을 평가하는 비모수적 방법으로 건설생산체계의 복잡하고 동적인 특성을 반영할 수 있는 유용한 성과측정도구로 활용되고 있다. 본 연구는 DEA 방법론을 적용한 건설 생산조직의 성과측정 문헌들을 체계적으로 분석하고, 주요 이슈들과 향후 연구과제를 도출하였다. 국내외 선행 연구를 분석하여 성과 측정 목표 및 대상, 자료 구조화 방법, 생산가능집합과 효율성 척도 선정, 벤치마킹 및 사후 검증 등의 일련의 단계로 이루어진 성과측정체계를 제안하고, 1997년부터 2013년까지 DEA를 적용하여 국내 건설산업 성과측정 연구를 수행한 21편의 학술지를 분석하였다. 관찰된 주요 특성 및 결과들은 건설기업이 자신의 상대적 효율성 수준을 진단하고, 개선 방향을 제시하고, 향후 예측을 하는데 DEA방법론이 유용하게 적용되어왔다고 나타났다. 그러나 타산업의 연구와 비교해볼 때 국내 건설산업의 효율성 측정은 제한적으로 적용되고 있었다. 본 연구는 연구대상, 자료의 구조화, 측정모형, 모형 검증 등에 대한 개선방향을 제시함으로써 향후 DEA을 적용한 건설산업의 생산성 제고를 위한 연구 체계를 수립하는데 활용할 수 있을 것이다. Data envelopment analysis (DEA) measures the relative efficiency of decision making units (DMUs) with multiple performance factors that are grouped into outputs and inputs. DEA has proven to be superior to simple aggregation of performance measures, and is also useful for evaluating the performance of construction companies for comparison with competitor performance. The purpose of this study was to survey literatures on the application of DEA methodology and to propose a methodological scheme to measure the performance of construction organizations. Articles on previous studies were surveyed and examined as part of a comprehensive review. The survey revealed that the application of DEA in the construction industry was li mited. Further, the survey indicated that there is a need for the development of a methodological framework on the special goals and subjects of performance measurement, methods of data structure and collection, selection of appropriate DEA models, analysis of results, and post-test. Based on the survey, this study identified and discussed the types of major issues and topics for future studies from a methodological perspective, which could be helpful to researchers interested in using DEA to study performance issues in construction organizations.

Purpose: The purpose of this study was to compare the changes in the pharyngeal airway space, tongue and hyoid bone positions according to the orthognathic surgical methods of mandibular prognathism. Methods: The subjects included 30 patients (16 males, 14 females) with the skeletal class III malocclusion. Group 1 (10 patients) underwent bilateral sagittal split ramus osteotomy (BSSRO) only; group 2 (10 patients) underwent BSSRO with genioplasty; and group 3 (10 patients) underwent BSSRO, Le Fort I osteotomy. We measured the lines between the selected upper air way, hyoid bone and tongue landmarks on the lateral cephalometric x-ray films of skeletal class III. The measurements were made preoperation, within 1 week after the operation, 3~6 months after the operation and 1 year after the operation. We compared and analyzed the measurements with matched paired t-test and independent samples t-test. Results: There were no postoperative changes in the nasopharyngeal airway space in group 3. The measurements of group 3 also increased during the follow-up period as compared to the preoperative measurements. In group 1, 2 and 3, the immediate postoperative oropharyngeal and hypopharyngeal airway spaces were decreased. In the following period, the hypopharyngeal airway space returned to the preoperative positions, but the oropharyngeal airway space was not significantly changed. The upper and lower tongue was posteriorly repositioned immediately after the surgery. During the follow-up period, the lower tongue position returned to the preoperative position, and the upper tongue position was not significantly changed. Immediately after the surgery, the B point was moved to the posterior position, and a slight anterior advancement was found in the follow-up period. Conclusion: Patients who received the mandibular setback surgery showed a decrease in the posterior airway space, and those who underwent maxillary advancement showed a significant increase of the nasopharyngeal airway space, which remained stable during the evaluation period. The change of the airway space, position of the hyoid bone and tongue did not differ according to the presence or absence of genioplasty.

The purpose of this study is to develop a customized residential selection service that recommends residential areas that meet individual needs so as to occupy an appropriate residential environment for students of Sinchon which is a university campus area. We have developed a housing selection service by integrating housing information and constructing a data model based on the investigation of the residential type and the current status of students in Shinchon area. In the preliminary survey, students were classified into 5 types of housing (Dormitory, Studio, Gosiwon, Boarding house, and Share house). Five residential areas were selected from Daehyun-dong, Yeonhyudong, Changcheon-dong, Daesin-dong, Nogosan-dong. The housing informations were divided into accessibility, cost, facilities, indoor environment, outdoor environment and common facilities. The university residence selection beta service is being divided into the housing selection recommendation process and the user participation type database expansion plan.

아마미오시마(奄美大島) 유이(油井) 豊年祭 ‘줄자르기(綱切り)’성격과 ‘탯줄자르기(へその緒切り)’

이윤선(Lee, Yoon-Sun) 비교민속학회 2013 비교민속학 Vol.0 No.52

일본 가고시마현 세토우치지역 유이마을의 음력 8월 15일 풍년제에 나오는 줄자르기의 성격에 대해 고찰했다. 쯔나키리(綱切り)는 신성한줄 자르기다. 큰뱀자르기라는 맥락에서는 한 세계의 죽임이요 또 한 세계의 창조다. 세 번에 걸쳐 낫으로 자르는 행위는 시작 기점을 완성하는 의미로 독해할 수 있다. 하쯔도효(初土俵) 또한 당 해에 태어난 신생아를 도효에 첫발을 내딛게 한다는 맥락에서 시작, 출발이라는 의미를 지닌다. 간농사마노 도효미마와리(.音翁の 土俵見回り)는 관음불의 巡視다. 가토돈(ガットどん)은 맹인이 강을 건너면서 복통을 일으켜 배변을 한다는 무언극이다. 강을 건넌다는 것도 이런 맥락에서 경계를 넘는 행위로 보이며 복통은 산통을, 배변은 출산을 뜻한다. 유이 풍년제는 겉으로는 한 해의 농사풍년에 대해 신에게 감사드리는 ‘추수감사제’의 성격을 지녔다. 이면에는 달과 풍요, 여성, 출생, 뱀, 재생 등의 의미를 담고 있다. 한국의 대보름, 추석의례와 같다. 그 모티프는 탯줄자르기에서 비롯되었다. 탯줄자르기는 김영균의 <탯줄코드>에서 제시한 것으로 줄다리기와 줄자르기의 모티프가 탯줄과 출산의 생물학적 과정을 반영한 것이라는 이론이다. 이것은 시작의례(Tape cutting on opening ceremony or opening ritual) 에 해당된다. 본고의 의의는 세 가지다. 첫째, 총의로서의 ‘줄다리기’에서 ‘줄자르기’로 논의를 확대했다. 둘째, 신성한 줄자르기가 탯줄자르기 모티프에서 출발한 것임을 확인하였다. 셋째, 오늘날까지 광범위하게 진행되는 오프닝 세러모니의 ‘테이프 커팅’이라는 의미를 민속학적 측면에서 연구할 단서를 마련했다. Yui Village is a part of SeotoUchi area(???町) in AmamiOshima(奄美大島), Japan. There is a special festival held every year on the 15th of August in the lunar calendar called Yui Harvest Festival. It is a divine and sacred ritual of cutting the straw rope. The straw was taken from the harvest on that season. It is known as Tsunakiri(綱切り). This long straw line is compared to a huge snake. The ritual is performed by two groups play the straw on each end as in a tug of war, and a man wearing a Lion’s mask holding a sickle will cut through the straw. When the straw has been cut, the two groups of men from the east and west sides of the village, previously holding the straw will tie it again. This ritual is done three times which signifies the beginning of the harvest festival. In this festival several rituals are performed which includes the followng. Another ritual follows called Hatsu Dohyo(初土俵). In this ritual, when a newborn baby steps on the ground for the first time, the Dohyo ritual begins. It is almost similar to Sumo wrestling. It is some kind of a sport. KannonSamano Tohyomimawari(?音翁の 土俵見回り), a certain group of people watching and observing the rituals. Kanon(?音) is a one of the Buddha. There is a pantomime performed called Gato Don(ガットどん). It is a story about a blind man crossing the river. As he was doing so, he had sudden abdominal pain and was not able to control his bowel. This play signifies three meanings. First, crossing of the river means leaving the old world for the new world. The stomach -ache represents the labor pains of a woman giving birth. And the bowel, the birth of a child. The whole festival, in my analysis, has two meanings. First is the surface (superficial) which signifies the harvest. Last one has a deeper meaning which includes the moon, woman, birth, snakes, and reincarnation. This is a symbolism of life. The cutting of the straw in the ritual signifies the birth of life just like in the cutting of the ribbon in a ceremony where a new company starts or begins its operation. It was suggested from <The umbilical cord code> by Young Kyoon Kim. The significance of this paper holds true on the following debate: First, “the tug of war” to cutting of the rope; Second, rope is compared to the umbilical cord; Third is the opening ceremony which has a broader meaning in Folklore study. A hint was suggested in this ritual. I believe that a further study should be taken.

목포지역 민속음악의 기반과 공연예술

이윤선(Lee Yoon-Sun) 역사문화학회 2012 지방사와 지방문화 Vol.15 No.1

목포지역 민속음악의 기반은 서남해 도서지역에 있다. 1900년대를 전후해 목포시에서 활동한 예술인들의 출신이 서남해 도서지역이라는 점을 확인하였다. 판소리, 기악 등 전문 예술에서 강강술래, 농악 등 집단 연희에 이르기까지 목포는 예술을 담는 용광로였다. 이 사실을 논거하기 위해 다양한 공연 장르를 역사적으로 정리하였다. 목포의 전통 예술은 민속음악에만 국한된 것이 아니었다. 창가, 가요 등으로 불리는 근대가요와 연극 등도 빈번하게 공연되었다. 이중 대표적인 것으로 극단 갯돌이 있다. 이 예술 재창조 작업에 나선 이들도 서남해 도서지역 출신들이 많았다. 극장을 포함해서 공연장도 다양한 형태로 설립되고 운영되었다. 목포는 전국에서 공연인구가 가장 많다. 동호인 그룹도 인구 대비 가장 많다. 목포공연예술학이라는 분과학문의 주창이 필요하다. 목포의 공연사 속에서 한국 민속음악의 발전 과정을 확실하게 볼 수 있기 때문이다. 서남해권역 민속예술을 공부하고 전파하는 고등교육이 필요하다. 서남해의 예술 전통이 다양한 형태로 목포로 이입되면서 오늘날의 문화적 전통을 만들었다. Mokpo is a city where folk music of the islands is based.Sometime around 1900, I discovered through research the art of music and dance that exists in the City. Mokpo has been the center of this music and dance art up to the present times. The Pansori and other several instruments were popularly used in Mokpo. Reason it became the center of this traditional art performance. The arguments involved to organize this genre had been historical. Mokpo traditional art was not confined to folk music only but modern music as of lately. Embarked on recreating this work of art, I discovered through information other forms of theater arts. For example, the GAETDOL had been the stage for these performances in the Southwestern area as documents revealed. Different types of artists have performed in the city of Mokpo. Even plain hobbyists groups enjoy going to Mokpo. The undersigned author have been suggesting the need to do a study and research on the Performing Arts because it show the developmental stages of Korea folk music. Also, higher education is needed in understanding the folk art of the the Southwest sea Region. Today, the cultural traditions of the city were formed by the flow of various types of Southwest's folk art.

2차원 전열해석을 통한 천장거치형 흡음 패널의 설계 조건에 따른 TABS의 방열 특성 평가

이윤선(Lee, Yoon-Sun),임재한(Lim, Jae-Han),정웅준(Chung, Woong-June) 한국건축친환경설비학회 2018 한국건축친환경설비학회 논문집 Vol.12 No.2

Low temperature heating and high temperature cooling systems have proven to be an energy efficient solution for conditioning building. Thermally activated building system (TABS) has become established as innovative systems for radiant heating and cooling system, and utilizes the building structure to store the thermal energy, reduce the peak loads and decrease primary energy demand in buildings. However, room acoustic performance should be of concern for the use of TABS. For this, free hanging acoustic panels (FHAP) were generally designed to reduce the overall sound intensity and reverberation time. This study aims to investigate the long-term effect of FHAP on cooling performance characteristics of TABS through two dimensional heat transfer simulation. In results, the coverage ratio up to 50% of the ceiling area by using horizontal FHAP has no significant influence on the cooling performance characteristics. And the vertical FHAP does not affect the cooling capacity from the ceiling at all.

생태유아교육의 전개를 통해서 본 생태민속학 담론

이윤선(Lee Yoon Sun) 한국민속학회 2007 韓國民俗學 Vol.46 No.-

광주전남유아공동체의 세시풍속 및 민속놀이 교육을 사례 삼아, 민속적 전통이 어떻게 유아교육에 적용되고 활용되는지를 분석해보고, 생태유아교육과 관련된 민속학의 역할은 무엇일 것인지 가늠해보았다. 이를 위해 광주전남유아공동체의 먹거리 및 세시풍속 학습사례들을 살펴보았고, 그 성과와 한계들을 또한 짚어보게 되었다. 그간의 교육사례를 통해 확인할 수 있었던 것은 생태유아교육을 표방하며 전개되는 프로그램들이 주로 민속학적 담론들, 혹은 민속학적 대상이 되는 주제들을 다루고 있다는 점이었다. 특히 세시풍속과 민속놀이, 민요 등은 직접적으로 민속학의 범주에서 논의될 수 있는 것들이라고 보았고, 이외의 프로그램들도 제3민속학 혹은 생태민속학의 범주내에서 논의될 수 있는 것들임을 확인하였다. 생태유아교육 관련 공동체는 태민속학의 지평을 실천하는 공동체임이 분명해 보인다. 다만, 그간의 도전과 실천과정을 통해서 볼 수 있듯이 지속적이고 광범위한 전인교육의 확장을 위해서 넘어야 할 산들이 많은 것 또한 사실이다. 이를 극복하는 방안중의 하나로, 생태유아교육공동체와 손을 맞잡고 산업적 폐해에 시달리는 아이들 살리기에 나서야 한다는 점을 드러내 보았다. 특히 실천하는 민속학으로서 민속학자들이 마땅히 해야 될 일이 아닌가 생각하였다. 이것은 오늘날 생태민속학을 표방하는 민속학자들에게 주어진 숙제라고 생각한다. 단순히 생태유아교육론을 보완한다는 측면에서의 裨補的 관점이 아니라, 실질적 생태유아교육의 동반책임자로, 相補的 관점의 역할론을 제기하고자 하는 것이다. 이에 대한 보다 실천적 범주로 도시민속학의 가능성에 대해서도 논의의 장을 열어 두었다. 결국 이상의 전개와 광주전남생태유아공동체의 교육 분석을 통해, 실천하는 민속학의 역할론을 이야기한 셈이다. 실사구시의 생태민속학, 이것은 생태유아교육과의 학제간 혹은 융복합화 형태로 연구되거나 정착될 필요가 있으며, 생태민속학뿐만 아니라, 도래하게 될 다음 단계의 민속학으로 확장되는 담론들을 형성시켜갈 좋은 소재가 될것으로 생각한다. This study is to be prepared in order to figure out what the role of folklore interested with Eco-kid Education is by analyzing how a folk tradition applies to Early Childhood Education in the case of the education of season's custom and folk play in Gwangju & Jeonnam Eco-kid Community. To do this, the study exams the learning cases of food and season's custom in the community and then figures out the results and the limits. What the study figure out in the existed education cases is that the programs developed as an Eco-kid Education mainly treat themes to be folkloric object or folkloric discussion. Especially, the study considers it as the directly discussed themes in a category of folklore to season's custom, folk play, folk song, and so on, and also finds out other programs could be discussed in the category of the third folklore or the ecological folklore. The community concerned with Eco-kid Education must be a community to practice “On-saeng-myeong” called by Jang, Hoe-ik, GAIA theory by James Lovelock, or even the horizon of ecological folklore by Im, Jae-hae. On the other hands, as we can see in the existed challenge and practicing process, there are many difficulties to solve in order to expand to a continuous and wide-ranged education for the whole man. Therefore, the study assumes what folklorists should do as a practical folklore is to cooperate with Eco-kid Education Community and then to lead a campaign which saves children to be suffered from industrial abuses. That is because the study considers it as the assignments of the folklorists who insist on the third folklore or the ecological folklore. The study would like to suggest the role of a complementary view as an really accompanied authority of Eco-kid Education, not the role of a supplementary view as a simple helper of the education. The study opens the field of discussion about the possibility of the folklore on city as more practical category of doing this. Conclusionally, through the development of the upper-mentioned contents and the analysis on the education of Gwangju & Jeonnam Eco-kid Education Community, it returns to the practical folkloric conclusion of Im, Jae-hae. A “practical” ecological folklore need to be studied or settled in an interdisciplinary or multi-compounded shape. The study considers the theme to be a good material which will expand to the fourth folklore as well as the third folklore.
