미더덕의 이용 다변화를 위하여 아임계수 추출물을 제조하고 생리활성을 평가하였다. 미더덕은 동결건조 분말 상태로 10, 30, 60분 동안 다양한 온도(50, 100, 200, 300℃)에서 추출되었다. 아임계수 조건은 ACE 저해 활성, 항산화 활성, AChE 저해 활성과 같은 중요한 생리학적 특성을 상당히 증가시켰다. 200℃, 60분 추출물에서 가장 높은 ACE 저해활성을 나타냈으나 더 높은 온도 조건인 300℃에서는 급격히 감소하였다. DPPH 라디칼 소거능과 ABTS라디칼 소거능은 300℃, 30분 추출물에서 공통적으로 가장 높은 값을 보였고, AChE 저해 활성 또한 같은 경향을 나타냈다. 이러한 결과는 아임계수 추출이 미더덕의 생리활성을 증가시키는 유용한 가공방법이 될 수 있음을 시사한다. For diverse application of Styela clava (Korean name: miduduck) as a food material, subcritical water (SCW) extract was prepared and its physiological activity was evaluated. To accomplish this, S. clava powder (0.1 g) was placed in a stainless vessel containing 10 mL of distilled water, after which SCW extraction was carried out at 50, 100, 200, and 300℃ for 10, 30, and 60 min. SCW treatment significantly increased important physiological properties of the extract such as angiotensin converting enzyme (ACE) inhibitory activity, antioxidant activity, and acetylcholinesterase (AChE) inhibitory activity. The highest ACE inhibitory activity was found in samples subjected to SCW extraction at 200℃ for 60 min; however, the activity decreased at higher temperature (300℃). The SCW extract of S. clava prepared at 300℃ for 30 min showed the highest antioxidant activity [1,1-diphenyl-2-picrylhydrazyl and 2,2’-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) radical scavenging activities] and AChE inhibitory activity. These results indicate that SCW extraction might be a useful method for increasing the physiological activity of S. clava.

국가기록 전시의 의미화에 대한 이용자 수용과 변화에 관한 연구

조민지,Jo, Min-ji 한국기록학회 2018 기록학연구 Vol.0 No.57

기록은 그 속성이 주는 견고하고 사실적인 능력으로 인해 시각적 이미지 를 통한 전시 프로그램에 주요 동원 매체가 되었다. 시각적으로 재현된 이 미지는 그 메시지를 소비하는 집단이 개별적으로 수용하여 의미적 이미지 로 발화된다. 본 연구는 기록이 사회적 생명력을 갖고 기록의 전시를 통해 돌아오는 것이며 이미지와의 작용을 통해 과거를, 기억을 ‘재매개’한다는 문 제의식에서 출발했다. 기록의 활용 중 전시를 이용자 분석의 대상으로 삼 은 이유는 전시가 기록을 선별, 배치하는 과정 속에서 그 기관의 정체성을 가장 분명하게 드러내 보일 수 있는 도구이자 매개체이기 때문이다. 이에 본 논문은 국가기록 중 특히 기억 갈등의 중심에 있는 “대통령” 기 록 전시를 기억의 문화적 실천 관점에서 분석한 후 이용자들의 실제 전시 관람과 설문을 통해 어떻게 전시 의미를 수용하고 저항하는가에 대한 실 증적 연구와 결과를 밝혔다. Records, especially the authentic records the nation secured, have an ontological feature of proof that is able to persuade the current present of the past present, and inherent in it is faith that originates from fundamental objectivity. Therefore the image of silence that such strictness of records creates realizes the detonation of specific memories through the act of visual exhibition. This research started from the notion that records achieve social vitality and return through its exhibition, as well as the critical awareness that it ‘re-mediate’ the past and memory through interactions with image. The reason for viewing the archival exhibition as the subject of user analyzation is that in the process where exhibition sorts and arranges records, it is the tool and mediation that most distinctly exposes the identity of the archives. Hence, this research first analyzes national archives, particularly the exhibition of “presidential” records, which is in the center of memory conflict, in the viewpoint of the cultural practice of memory. Afterwards, it discusses empirical research and results on how users accept and resist the meaning of the exhibition through actual surveys of users after their viewing of an exhibition.

국산 양식 홍합 함유 식빵의 제조 및 생리활성 평가

조민지(Min-Ji Jo),김윤아(Yun-Ah Kim),이승철(Seung-Cheol Lee) 한국식품영양과학회 2016 한국식품영양과학회지 Vol.45 No.11

우리나라 남해안에서 많이 양식되고 있는 홍합(진주담치)은 다가 고도 불포화지방산을 비롯한 다양한 유용 물질을 함유하고 있으며 이로 인한 항산화능, 항비만능, 알코올분해 효소 촉진능 등의 생리활성이 보고되었다. 본 연구에서는 홍합의 이용성 다양화를 위하여 홍합 분말을 첨가한 식빵(0,0.25, 0.5, 0.75, 1%, 홍합/밀가루, w/w)을 직접반죽법으로 제조하여 그 특성을 분석하였다. 홍합분말이 첨가될수록 식빵의 명도는 감소하였고, 적색도와 황색도는 증가하였다. 홍합분말의 첨가는 식빵의 비용적에 크게 영향을 주지 않았지만, 항산화능(DPPH 및 ABTS 라디칼 소거능)은 증가시켰다. 또한, 홍합분말의 함량이 증가할수록 알코올 탈수소효소와 아세트알데히드 탈수소효소의 활성도 증가하였다. 관능검사에서는 홍합분말 1% 첨가 식빵이 맛, 향, 물성과 선호도에서 상대적으로 높은 점수를 얻었다. 이상의 결과는 홍합이 식빵의 경도와 강도에 큰 영향을 주지 않고 생리활성을 향상할 수 있는 소재로 활용될 수 있음을 의미한다. White breads containing Korean blue mussel (Mytilus edulis) powder were prepared and characterized. WB (white bread without blue mussel) and four different MBs (white breads containing blue mussel; number in front of MB means added % of blue mussel powder per wheat flour) were prepared by the straight dough method. With addition of blue mussel to bread, lightness decreased, whereas redness and yellowness increased. Addition of blue mussel did not significantly affect specific volumes of breads. DPPH and ABTS radical scavenging activities significantly increased with increasing blue mussel content. Addition of blue mussel to breads also increased alcohol dehydrogenase and acetaldehyde dehydrogenase activities. In the sensory test, 1MB acquired relatively high points for taste, flavor, texture, and preference. The results indicate that blue mussel can be applied to white bread to improve physiological functions without reduction of physicochemical characteristics.

물류센터 경유를 고려한 화물운송 경로 모형 개발

조민지(Min-Ji Jo),김환성(Hwan-Seong Kim) 한국항해항만학회 2015 한국항해항만학회지 Vol.39 No.1

국내의 화물 운송량은 꾸준히 증가하고 있으며 이에 따라 내륙지역의 화물운송량 예측에 관한 연구가 활발하게 진행되고 있다. 하지만 종래의 기종점 자료(O/D Data)는 화물 운송수단의 출발지와 목적지를 조사하여 구축하였으며 이는 화물의 운송 특성을 제대로 반영시키지 못하는 문제점을 지니고 있다. 화물의 운송은 단순히 출발지에서 목적지로 화물을 운반하는 것이 아니라 화물운송 도중에 운송수단을 변경하거나 화물의 임시 보관이 필요한 경우가 발생하므로 화물운송모형에서는 중간 경유지(물류센터 또는 내륙컨테이너기지)를 포함시켜야된다. 본 논문에서는 이러한 중간 경유지를 고려한 기종점 자료의 필요성을 인식하였고 물류센터를 고려한 화물운송 경로에 대한 모형을 제시하고자 한다. 본 연구가 제시하는 화물운송 경로모형은 각 구간별 운송계수를 설정하고 이에 따라 화물량을 예측하는 모형으로서 유전 알고리즘을 이용하여 모형을 검증하였고 오차의 범위가 ±1.0%이내로써 모형은 타당한 것으로 판단된다. Inland transport becomes more and more important in connecting ports with inland. Therefore, studying on cargo flow from ports to regions has been active in progress by many researchers. However current statistical data of freight flow from origin locations to destination locations does not reflect the exact characteristics of freight flow. Also, they also do not reflect the characteristics of multimodal transport system in which cargos go through intermediate locations such as logistics center or inland container depot. In growing up the emergent need of rebuilding statistical data for freight flow from origin locations to destination locations, this paper will propose a freight flow model with logistics center and it will be verified by genetic algorithm through the simulation scenarios.

미군정기 후반전, 현지조사와 지방여론

조민지 ( Min Ji Jo ) 서울대학교 국사학과 2016 韓國史論 Vol.62 No.-

This thesis focuses on the series of ‘Field Operations’ in the late 1947, conducted by the Office of Civil Information(OCI) which did the central role in public information of US Armed Forces In Korea(USAFIK) during the latter-half of the occupation. From July to December in 1947, the OCI dispatched its survey teams 7 times to each local province of South Korea, using ‘Mobile Educational Train’ which had used for public relations in local area. During the survey team entered each village(Ri) for public information activities, they collected field intelligence including the opinions of residents as well. These were subsequent public opinion polls conducted on a nationwide scale after a series of surveys by Department of Public Information(DPI) in 1946. In the ‘Field Operations’, level of analysis of USAFIK enhanced enough to cover each village for the first time throughout whole occupation. In late 1947, it became more important for USAFIK that the people of South Korea approve the American course of action since the prospect of 2nd US-USSR commission was getting dim. As the alternative course of action that US had intended, implement of general vote took an essential part to justify the ‘Separate Government’ so that the countrywide supports were required. However, the atmosphere in local region of South Korea remained deteriorated since so-called ‘October Resistances’ in 1946, which resulted from hitherto Seoul-centric policies. USAFIK regarded the leftist’s propaganda mainly responsible for agitating local opinions to stimulate regional riots, therefore they planned the reinforcement of the information activities in rural areas. As one of the course of actions under these tendencies, the Office of Civil Information conducted a series of the ‘Field Operations’ to examine current atmosphere in local regions, especially around the selected areas to be built the potential Information Center of OCI. The ‘Field Operations`` were conducted in rural areas collecting the opinions of local residents, whereas most of the past surveys of DPI were merely concentrated on those of Seoul citizens. The result from each survey indicates that the public opinions of local residents were fundamentally affected on various issues pertaining to different local interests. Nevertheless, the most influential factor for arousing the public opinions significantly in every region was the food issue. Furthermore, in case of rural villages, the key factor dominating degree of food shortage was the rice collection program of USAFIK applied in their region. The effect of rice collection program was so enormous that it did not related merely the approval rate for USAFIK, but even impacted on the attitudes of local residents toward personal Americans, or their opinions relating to the regime of North Korea. This seems similar to the effects of ration policies or rice price in urban areas. Even though some of existing studies have excessively concentrated on clarifying the political orientations of residents, political issues might have not been existed separately from local interests in their lives whether they inclined left or right. At least after the ‘October Resistances’, USAFIK had already recognized these possible influences of food issue affecting on public opinions in rural areas. However, they had decided to intensify technical skills for playing it by ear rather than try to deal with the practical problems fundamentally. For this reason, they sought for the most efficient way to promote the American line of policies in each village. As a result of these attempts, some information concluded from the ‘Field Operations’ pertaining to the characteristics of local villages in South Korea were applied to the following information activities of OCI. The conclusion emphasized the decentralization and isolation of each village, hereby urgent necessity of US information activities was justified for providing local residents who were easily taken into the control of extremists with proper information without any bias. Moreover, it could strength the argument that building the local information centers of OCI would serve as permanent basis for finding the most suitable way to implement information activities in each area. The conclusion of ‘Field Operations’ was not entirely different from the usual position that USAFIK had taken throughout the whole occupation. Before the operations, USAFIK had already emphasized the passive characteristics of public opinions to blame leftist’s propaganda for arousing local resistances. Accordingly, the headquarters in Seoul, local military governments, and the troops stationed in regional areas closely cooperated to implement combined operations which tried to control public opinions for the right-way reorganization of local society. In addition, the local polices and rightist groups actively collaborated with these combined operations as well. Even if the conclusion of ‘Field Operations’ mentioned that the efficiency of the public information was the most decisive factor for repressing local resistances, in many areas the potential resistances had been already suppressed physically before the information activities were actually launched. Any political activity in local areas could be valid only in the fixed frame given by USAFIK. However, when the public opinions of local residents were expressed directly in several significant circumstances, it might have been unwarranted that the effect of propaganda or public relations was clearly unilateral as the USAFIK’s expectation. The numerous historical experiences that the local residents were sharing had decided which political group would take the initiative in such village. The common historical experiences of such communities often combined different factors depending on the certain situations, which could trigger serious resistances off in rural areas. Although propaganda might have its own role in these courses of actions, it was not a sole factor to making local opinions. Admittedly, temporary superiority of rightist in rural areas seemed to be successful for transplanting a few of rightist slogan such as pro-American or Anti-trusteeship. Nevertheless, those achievements could not cover the substantial problems involved the survival of people. Consequently, the conditions of each region which had worked as fertile backgrounds for leftist propaganda could not be improved through the following information activities after the ‘Field Operations’.

항만 연계활동에 기초한 이산화탄소 배출량 추정

김환성(Hwan-Seong Kim),조민지(Min-Ji Jo) 한국항해항만학회 2010 한국항해항만학회 학술대회논문집 Vol.2010 No.춘계

항만 산업의 발달로 인해 국내 내륙운송산업이 연간 680백만톤 수송할 정도의 규모로 발전하였다. 하지만 우리나라 내륙운송은 80%가 공로운송에 편중되어 있어 여러 가지 사회적 문제를 야기하고 특히 온실가스배출문제가 심각하게 대두되고 있다. 전 세계적으로 기후변화에 관심을 가지면서 기후변화협약, 교토의정서, 탄소배출권제등 다양한 협약과 규제들이 생겨나고 있어 내륙운송 산업에서도 CO2 배출량에 대한 관심이 높아지고 있다. 본 논문에서는 우리나라 6대 항만을 기준으로 현재 항만 내에서 발생되는 CO2와 더불어 각 항만을 기준으로 내륙운송의 CO2 배출량을 산정하고 향후 항만의 처리 물동량이 증가함에 따른 국내 내륙운송의 CO2 배출량을 예측하고자 한다. As the quantity of goods transported, port industry and inland transport industry have developing to transport 630million ton goods annually. And the inland transport industry consists of ground transport for almost 80% of total transported goods. But, ground transport causes some serious problems especially the emission of greenhouse gases from trucks. According to issue "global warming", many regulations and agreements with countries in the world are becoming necessary and it is being fulfilled now. It is sure that Korea will have duty to reduce CO2 emission from 2013. Thus inland transport must cut off CO2 emission level. Therefore this paper will address that the calculation of CO2 emission under route of transportation container from six major container ports in Korea. And then, it will predict CO2 emission Of inland transport industry according to increasing container traffic rate at ports.
