This study tried to develop Siraegi by boiling it down in soy seasoning sauce with excellent sensory attributes and evaluate the quality characteristics in order to enhance the value of traditional agricultural products, dried radish leaves. Sugar content of the seasoning sauce were finally established at 30% (w/v) compared with the starch syrup, which was added to the sauce through sensory evaluation among four groups, 0%, 30%, 60% and 100%. The texture (breaking strength) of Siraegi which was boiled for 30 minutes in water with baking powder was reduced by showing softening effect ranging from 7.6% to 42.1% as the amount of added baking powder was increased. The color of braised Siraegi produced with prepared a seasoning sauce and different content of baking powder, the brightness significantly decreased with an increase of baking powder. The reduction effects of breaking strength ranged from 25.6% to 43.9%, resulting a significant difference. The pH of braised Siraegi with a seasoning sauce significantly increased from 5.71 to 6.04 as the amount of added baking powder was increased, while its acidity was decreased. Sensory evaluation showed significant values for hardness and toughness as the values dropped when compared with the control (p<0.001), and overall acceptability of the group with adding 0.2% baking powder was best (p<0.001). In conclusion, baking powder could be considered as softening agent shorting the cooking time and improvement of the acceptability. Furthermore, it was expected that the newly developed soy sauce barised Siraegi using the dried radish leaves would be successfully utilized by side dishes in the food preparation industry.

This study presents effects of surface treatment on the structural behavior of RC beams strengthened with FRP(Fiber Reinforced Polymer). Tests are performed with two groups of specimens. One group didn’t carry out grinding the surface of beams and cure the primer adequately. Another group carried out grinding the surface of beams and cured the primer during more than 24 hours. The results show that the surface treatment of beams effect the capacity of strengthening with FRP. If the surface of beams is handled smoothly and the primer is cured adequately, the capacity of adhesive strength between beams and FRP is improved highly. So, the beams can be sustained the more loads.

「인간가족 The Family of Man」전의 이면

김나정(Kim Na-jung) 현대미술사학회 2008 현대미술사연구 Vol.24 No.-

This study presents an investigation into “The Family of Man”, which was planned by Edward Steichen(1879-1973), the director of Department of Photography at the Museum of Modern Art(MoMA), in 1955. After a huge success at the museum, the photography exhibition went on a tour around 38 nations in the world under the sponsorship of the United States Information Agency(USIA) for seven years. There is no doubt that it’s one of the monumental blockbuster exhibitions in the 20th century with the total visitors of nine million. Such a popular success and personality, however, rendered the exhibition familiar and not fully understood at the same time. In addition to the temporary conditions of the exhibition, the fact that the exhibition didn’t deal with the complete works of consistent artists made it rather difficult for the conventional art critics to cover it. Consisting of 503 works by 273 photographers, the exhibition had a variety of status and origin of the photographers and photos, which didn’t allow the critics to regard them as consistent ‘artistic works’ by an ‘artist.’ Thus this study tried to deal with the exhibition as a kind of text telling a story of America and arts in the 1950s covering the entire tour from 1955 to 1962 and assuming the curator Steichen as the text’s author. Accordingly it reorganized an artistic exhibition that doesn’t exist any more in the context of the world history and artistic history of the times. The operation was intended not only to interpret the hidden sides of the exhibition, which treated the ‘history’ of mankind of the times as the ‘mythology’ that mankind was one family, but also to reveal that America’s modernist arts and modern museums that argued for only ‘arts’ with the exclusion of ‘politics’ were actually the products and devices of the mainstream ideology that they belonged to. Based on the previous discussions that took a critical approach to the exhibition in the political, social and economic context, the study attempted to find the position and meanings of the exhibition in the history of American’s modernist arts. The impulses of antinomy inherent in modernist arts were detected in that MoMA applied the opposite positions of depoliticized aesthetics and propaganda to its ‘paintings’ and ‘photos’ respectively during the period of the exhibition. Thus the study considered the history of paintings and photos, which the conventional formalistic criticism tried to separate, as the relational terms tangled up with each other in the cultural policies during the Cold War period. For the discussion purposes, the background of planning the exhibition was reviewed. The United States gradually formed its national identity called Americanism as there came the Cold War period after the Second World War under the social situations in the 1950s. The background of the exhibition was also examined from the perspective of arts history through the process of America’s modernist arts being institutionalized in MoMA and photography being integrated into arts there. It was under those contexts that “The Family of Man” held in MoMA was analyzed in details. The conviction in the objectivity of photographs that made the materials of the exhibition was established by the identity of photographers during the Golden Age of photojournalism after the war, the institutional device such as publications, and social discourse. The installations of the exhibition had popular features added to the abstract forms of Modernism. It’s also pointed out that the exhibition’s narrative based on the objectivity of photography and modernist aesthetics was nothing but the mythology of sentimental humanism that would erase the unique historical situations. In other words, the university of the worldwide ‘Family of Man’ that the exhibition tried to talk about was none other than the American vision for the ‘one world’ or Americanism in the end. That’s how the exhibition ended up with being used as a tool of

가열 조건에 따른 단호박 페이스트를 제조하기 위해, 단호박을 15분 간 초벌 증숙한 뒤, 고압가열 처리 0분(A), 10분(B), 20분(C), 40분(D) 실시하여 실험군의 품질특성 을 조사하였다. 그 결과 일반성분의 경우, 대체적으로 고 압가열 처리 유무에 따른 유의적 차이가 관찰되었으며, 고압가열 처리한 B, C, D 실험군의 수분함량, 조단백질, 조섬유가 고압가열 무처리군 A에 비해 감소하였고, 가용성 무질소물은 증가하는 것으로 나타났다. 가열 조건별 단호박 페이스트의 수용성식이섬유는 고압가열 20분 처리군인 C의 측정치가 2.02로 가장 높았으며 무처리군인 A의 1.60 보다 증가하였고, 고압가열 처리 40분의 경우 오히려 감소하는 것으로 나타났다. 색도의 L 값은 고압가열 무처리군인 A가 52.20에서 고압가열 처리 10분, 20분, 40분으로 시간이 증가함에 따라 각각 50.33, 49.46, 48.06으로 감소하였고, a 값과 b 값 또한 유의적인 차이를 보이며 감소하였다. 현미경을 통한 단호박 페이스트의 현탁액 입자를 관찰한 결과 카로티노이드를 포함하는 유세포가 관찰되었으며 고압가열 처리와 그 시간이 증가함에 따라 단호박 유세포의 변형이 뚜렷하게 관찰되었으나, 부유안정성 실험 결과 실험군 A, B, C, D 간 차이가 없었다. 이때, 가열조건의 선택은 수용성 식이섬유의 증가, 환원당 증가, 단맛의 관능특성이 유의적으로 높고, 전반적 기호도가 가장 우수한 것으로 나타난 고압가열 처리 20분인 C 실험군으로 결정하였다. 선택된 조건의 단호박 페이스트에 식품가공 시 널리 사용되는 검류인 xanthan gum, locust bean gum, guar gum을 단호박 페이스트에 종류별로 첨가하여 부유안정성을 확인하였는데, 이 결과 guar gum, locust bean gum, xanthan gum 순으로 부유안정성 효과를 나타냈으며 locust bean gum과 xanathan gum은 비슷한 정도의 효과를 보였다. 또한 관능검사를 통한 기호도 확인 결과 텍스쳐와, 전반적인 기호도가 가장 우수했으므로 locust bean gum(0.2%) 첨가 단호박 라떼의 품질이 가장 적절할 것으로 판단된다. For the production of pumpkin paste with respect to heating conditions, we steamed the pumpkin for roughly 15 min, heated it with high pressure treatment for 0 min (A), 10 min (B), 20 min (C), 40 min (D), and subsequently investigated the quality characteristics. Generally a significant difference was observed between the pumpkin paste treated with and without high-pressure heat. The values of water content, crude protein and crude fiber of the high-pressure heat-treated groups B, C, D were decreased compared with untreated group A. The soluble fiber in experimental group B sweet-pumpkin paste treated with high-pressure heat for 20 min was higher than the control, and the highest value at 2.02. Experimental group D sweet-pumpkin paste treated with high-pressure heat for 40 min was found to have a decreased soluble fiber content relative to the control. The L value for the color of the group A untreated control sweet-pumpkin paste (no high-pressure heating) decreased as the time increased from 10 min to 40 min, with L values of 50.33, 49.46, and 48.06, respectively. The b value for the color of the sweet-pumpkin paste also decreased, showing a significant difference. Taking into account all the results, we chose experimental group B in order to prepare sweet-pumpkin latte. We used 0.2% gum (xanthan gum, locust bean gum, guar gum) as a stabilizer. Sweet-pumpkin latte with xanthan and locust bean gum has a suspension stability effect that lasts 90 min. The L and b values of sweet-pumpkin latte with gums increase and a value decrease compared with the control. In terms of the overall acceptance of the sweet-pumpkin latte, the experimental group with xanthan gum scored the best.

영유아보육과 발달을 둘러싼 글로벌 이슈 및 현황탐색 및 지속가능개발목표(SDGs)에 대한 시사점 연구

이기석(Ki Seok Lee),김나정(Na jung Kim) 국제개발협력학회 2018 국제개발협력연구 Vol.10 No.3

이 연구는‘지속가능개발목표(Sustainable Development Goals, 이하 SDGs)’시대로의 진전과 함께 새롭게 주목받고 있는‘영유아보육과 발달(Early Childhood Care and Development, 이하 ECCD)’의 지속적발전과 SDGs 목표 달성을 위해 공여국과 수원국을 모두 아우르는 국제사회가 함께 추진해 나가야 할 전략적 목표와 정책적 방향을 제시하였다. 관련하여 모두를 위한 교육(Education for All, 이하 EFA)목표가 합의되어진 지난 2000년 이후로, 영유아보육과 교육(Early Childhood Care and Education, 이하 ‘ECCE’)에 대한 국제사회의 관심과 중요성은 지속적으로 증대되어져 왔음을 주목할 필요가 있다. 아울러 같은 시기인 2000~2015년 사이 시행되어져 온‘새천년개발목표(Millennium Development Goals, 이하 MDGs)’는 EFA 목표와 함께 교육 분야를 포함한 이 시기의 가장 핵심적인 국제개발협력 목표 중 하나라고 할 수 있다. 그러나 국제사회는 ECCE를 포함한 EFA 목표의 가시적 성과에 대해 전반적으로 기대수준에 미치지 못하는 평가하고 있으며, 같은 시기의 MDGs는 ECCE를 아예 목표 범위로 포함하고 있지도 않은 것은 주지할 만한 사실이다. 결국 이것은 영유아보육과 교육과 관련한 글로벌 교육 문제들의 발전과 진전을 가로막는 주요 장애요인이 되었다고 할 수 있다. 이러한 MDGs, EFA 목표의 실패 경험으로부터 국제사회는 공여국과 수원국의 상호 책무성을 강조한 새로운 개발목표인‘지속가능개발목표(SDGs)’를 수립한 바 있으며, 이를 실천적으로 지원하기 위해‘교육 2030 실행 계획(Education 2030 Framework for Action: FFA)’라는 세부 전략을 함께 마련하여 시행해 오고 있다. 특히 EFA 시대의 ECCE가 영유아보육과 교육의 문제에 초점이 맞춰져 있었다고 한다면, SDGs 시대의 ECCD는‘영유아보육과 발달(Early Childhood Care and Development)’의 문제로 영유아 지원의 범위를 더욱 확대한 것이 특징적인 사실이다. 그러나 SDGs와 연계한 국제교육개발협력 맥락에서 공여국, 수원국, EFA 기간 ECCD 현황 모두를 아우르는 종합적, 통시적 관점에서의 연구가 부족한 것은 주요 한계점이라고 할 수 있다. 이러한 맥락에서 이 연구는 ECCE, ECCD 관련 국내외 문헌분석, 인터뷰, 현지조사를 연구 방법론으로 하여 최근 관련 동향 및 핵심 쟁점을 종합적으로 탐색하였다. 특히 ECCD의 정책과 확산구조, 보건(Health)과 위생(Sanitation), 영양(Nutrition), 안전(Safety) 등의 통계 및 교육과 보육 시스템 거버넌스 등에 대한 공여국, 수원국 간 비교 연구를 통해 향후 ECCD 부문 정책 마련과 사업추진방향에 대한 학술적 근거를 마련하였다. 아울러 공여국, 수원국 모두를 아우르는 상호 책무성 관점에서 향후 국제사회가 ECCD 발전 SDGs 목표 달성을 위해 우선순위를 둬야할 핵심 이슈, 한계점, 정책적 방향 등을 함께 제시하였다. This study investigates strategic objectives and policy directions for the international community including both donor and recipient countries to ensure early childhood care and development (“ECCD”), the importance of which is unprecedently emphasized as part of the global efforts to advance the sustainable development goals (“SDGs”). Since the EFA goals were agreed upon by the international education community in 2000, early childhood care and education (“ECCE”) began to receive increasing policy attention. In line with the EFA goals, Millennium Development Goals (MDGs) - effective 2000 to 2015 - constituted one of the pillars in international development cooperation. Nevertheless, results of EFA including commitment to ECCE fell short of initial expectations and the MDGs did not incorporate the ECCE in its goals and targets. This hindered the global efforts to ensure global education goas including for the area of ECCE. Faced with setbacks from the era of EFA and MDGs, the international community has collectively agreed on the establishment of a new vision for international development - Sustainable Development Goals (SDGs) which call upon accountabilities from both donor and recipient countries. In addition, Education 2030 Framework for Action (FFA) was initiated for these global efforts with concrete action plans. The SDGs promote ECCD which is regarded as a broader and integrated concept than ECCE1), but there is lack of research investigating the ECCD landscape of donor/recipient countries in connection with the era of EFA and SDGs. In this context, this paper reports key findings of domestic and international literature review, interviews and field studies conducted to explore recent trends and emerging issues surrounding ECCE and ECCD. The study provides a comparative narrative for the ECCD governance in terms of policy directions and dissemination, health and sanitation, nutrition and social safety between donor and recipient countries as well as an academic groundwork for policy formation and engagement for developing countries. The study concludes with key issues, major challenges and policy directions to be considered for both donor and recipient countries in their efforts to ensure ECCD as well as to advance the SDGs.

The objective of this study was to develop a physical education program, which will induce interest and heighten satisfaction of female high school students and to provide the basic material to set up a plan aimed at encouraging active participation of female students. The study was based on the analysis of the level of interest and satisfaction of female high school students from various composition of class on physical education curriculum. The research results analyzed through the above method and process could be summarized as follows: The interests of female high school students varied according to the composition of the physical education class. The all girls` class of co-ed high school showed the most interest while the co-ed class of co-ed high school displayed the least interest. The environmental variant, which affects the interest rate of P.E. with different class composition, was curriculum of the physical education in co-ed class of co-ed schools, all girls` class of co-ed schools and girls` high schools. The environmental variant, which affects the satisfaction of P.E., was facility and equipment in co-ed classes of co-ed schools, and the curriculum of the P.E. in all girls` classes in co-eds as well as girls` high schools. The results were the same in the case of P.E. class environmental variant, which needs to be urgently improved to enhance the interest and satisfaction of high school girls on P.E. The satisfaction of girls` high school according to the composition of P.E. class showed significant difference according to composition of P.E. class, curriculum of P.E., the teaching method of the physical educator and between co-ed classes and all girls` classes. The reverse was true for the recognition of connection between P.E. education in school and social sports. The following conclusion could be derived from the research results: The level of interest and satisfaction of P.E. differed according to the composition of the P.E. class.

기업 부패과정에 대한 시스템다이내믹스 접근 -퍼컬레이션 모형을 중심으로-

This study explores the process of corporate corruption via a percolation-based system dynamics model. The preliminary model is an agent-based model constructed in the terms of the corruption networking between ego and other. In the model, the agents behave depending on percolation rules, which represent (1) passing on the corruption opportunities and (2) accepting it. To describe the percolation process in the networks, we develop a further complicated model by combining the basic model with the Bethe lattice. Through the complicated model, we suggest (1) the dynamics of the systemic corporate corruption, (2) 4 patterns of the corruption, and (3) the institutionalization of the corruption. These simulation results provide theoretical and practical implications.
