Mesenchymal stem cells (MSCs) have ability to differentiate into multi-lineage cells, which confer a great promise for regenerative medicine to the cells. The aim of this study was to establish a method for isolation and characterization of adipose tissue-derived MSC (pAD-MSC) and bone marrow-derived MSC (pBM-MSC) in pigs. Isolated cells from all tissues were positive for CD29, CD44, CD90 and CD105, but negative for hematopoietic stem cell associated markers, CD45. In addition, the cells expressed the transcription factors, such as Oct4, Sox2, and Nanog by RT-PCR. pAD-MSC and pBM-MSC at early passage successfully differentiated into chondrocytes, osteocytes and adipocytes. Collectively, pig AD-MSC and BM-MSC with multipotency were optimized in our study.

본 연구는 최근 관심이 집중되고 있는 직장 내 괴롭힘에 관한 연구로, 조직 차원에서의 직장 내 괴롭힘의 예방과 대응책 마련을 위해 경영학적 접근을 시도하였다. 개정된 근로기준법에서 정의한 직장 내 괴롭힘의 행위 요건인 관계적・지위적 우위성, 업무 관련성, 신체적・정신적 고통을 바탕으로, 직장 내 괴롭힘을 예방하는 선행요인을 직무 자율성, 다양성 관리, 직무 적합성, 성과관리 공정성, 근로시간 자율성, 상사지원으로 구성한 여섯 가지 인사관리 특성을 고려하였다. 귀인이론에 기반하여 그러한 인사관리 특성이 조직구성원의 지각을 통해 직장 내 괴롭힘 발생을 감소시키는 효과를 분석하였다. 또한 조직차원의 인사관리특성 효과를 조절하는 변인으로 근로자의 공식적 참여를 수반하는 근로자발언기구의 효과를 살펴보았다. 연구 결과, 각 인사관리 특성을 결합한 시스템의 전략적 활용이 직장 내 괴롭힘을 감소시키며, 노조와 같은 근로자의 공식적 참여가 보장되는 근로자발언기구의 활용과 함께 이루어질 때 직장 내 괴롭힘의 감소 효과는 강화되는 것으로 나타났다. This study deals with workplace bullying, which has recently attracted attention, and tries an institutional approach to the prevention of workplace bullying at the organizational level. We considered the human resources management system’s characteristics based on the workplace strategies as the fundamental way to make the employees away from bullying at the organizational level. Moreover we identified the interaction effects between the characteristics of the organization"s human resources management system and the institutions that lead to the involvement of employees. This study considered six characteristics of human resource management system, which consist of job autonomy, diversity control, task suitability, performance control justice, working hours autonomy and superior support, as the preceding factors to prevent workplace bullying. We also revealed that the strategic use of system bundles which combine the characteristics of each human resource management system reduces workplace bullying, and that the reduction effects of bullying can be strengthened when it is done with the participation of employees.

문화예술 경험 요인이 문화예술향유에 미치는 영향:미술 전시회 관람을 중심으로

이아영(Lee, Ah Young),김범수(Kim, Bumsoo) 한국예술경영학회 2021 예술경영연구 Vol.- No.58

국민의 문화예술향유가 확대됨에 따라, 문화예술 관람에 영향을 미치는 요인에 대한 연구가 지속적으로 진행되고 있다. 그러나 대부분의 실증연구는 인구통계학적및 환경적 요인에 치중하여 분석을 수행하였으며, 주로 순수문화예술 영역 내 장르를 구분하지 않고 수행된 경우가 많은 실정이다. 따라서 본 연구는 국민의 순수문화예술 향유 중 특히 미술전시회 관람에 영향을 미치는 요인을 실증적으로 분석하는 것을 주요 목적으로 한다. 이에 6개년의 ｢국민문화예술활동조사｣ 결과를 통해 수집된 총 56,588개의 표본을 활용하여 다중회귀분석 및 다원 분산분석을 수행하였다. 분석 결과 문화예술행사, 문화예술교육, 문화예술동호회에 참여한 경험이 있는 집단의 미술전시회 평균 관람횟수가 더 많은 것으로 나타났다. 또한 변수 간 상호작용효과를 확인하였다. 즉 문화예술행사, 문화예술교육, 문화예술동호회에 모두 참여한 경험이 있는 집단의 미술전시회 평균 관람횟수가 더 많은 것으로 나타났다. 본 연구는 다년간 수집된 빅데이터를 취합 및 분석하여 개인의 문화예술경험이 미술전시회 관람에 영향을 미치는 것을 실증적으로 확인했다는 점에서 의의가 있으며, 미술전시회 관련 중기 정책의 수립에 정책적 함의를 제공할 수 있을 것으로 기대된다. This study empirically analyzes the factors that affect the people’s enjoyment of pure culture and arts, especially art exhibitions. We use 56,588 sample data from the “The Survey of Cultural Enjoyment” collected by the Ministry of Cultrure, Sports and Tourism over the last 10 years and perform multiple regression and Multi-Way ANOVA to analyze the effect of individual’s cultural experience on art exhibit visits. The results of the analysis show that the experience of participating in culture and arts events, culture and arts education, and participation in culture and arts clubs have a positive effect on the art exhibition visits. We also identify the positive interaction effects between the three independent variables. In other words, it was found that the average number of visits to art exhibitions was higher for groups who had experience of participating in culture and arts events, culture and arts education, and culture and arts clubs. This study provides a first empirical analysis on personal factors influencing art exhibition visits in Korea and lays the groundwork for future studies in developing a comprehensive predictive model for cultural art visits. In addition, we give policy implications and suggestions specifically, mid-term policies related to promoting art exhibition visits as an extension of individual’s engagement with pure culture and arts through big data analysis.

Objectives: The purpose of this study was to identify the tendency toward depression and fatigue in early postpartum women and to determine the relationship between the symptoms of these conditions, according to the women`s Sasang constitutions. Methods: In this study, 73 healthy postpartum women were analyzed according to Sasang constitution: 33 Taeeumin, 22 Soyangin, and 18 Soeumin. Symptoms of depression and fatigue were assessed using the Edinburgh Postnatal Depression Scale-K(EPDS-K) and the Fatigue Continuum Form(FCF), respectively, on the fourth(time 1), seventh(time 2), and fifteenth(time 3) days postpartum. Sasang constitutional types were determined by a medical specialist, using results from the Two Step Questionnaire for Sasang Constitution Diagnosis (TS-QSCD). Results: 1. The overall depressive symptoms and fatigue scores decreased significantly over time in early postpartum women. 2. The mean scores for the EPDS and FCF were higher in the Soeumin group than in other groups. The scores for EPDS and FCF dropped sharply in comparison to a former level in the Soyangin group. And the mean EPDS score was lower in the Soyangin group than in other groups. The EPDS and FCF scores in the Taeeumin group changed slightly over time. However, these results were not statistically significant according to Sasang constitution. 3. The relationship between postpartum depression and fatigue showed a significant positive correlation. Conclusions: These results suggest that, in early postpartum women, depressive symptoms and fatigue differ according to Sasang constitution.

The purpose of this study was to investigate expression characteristics of korean traditionality in restaurants & Cafes which adapted thatched roof & shingle-roofed house. As a method of this study, a case study was made to investigate for exterior and interior elements(roof type, facade, floor, wall, ceiling, door & window) of 12 restaurants & cafes in Seoul and Kyunggi Province from June 10, 2013 to December 1, 2013. The results of this study were as follow: First, traditional transformation was mostly used among the traditional expression methods. But, there was not many traditional reinterpretation method. Second, looking at each component, traditional reproduction method mostly used for roof, column and ceiling to emphasize facade. Traditional transformation method can be divided into 3 ways in detail. The first method is mixing materials of modern and traditional, and the second one is transforming traditional material and combining this with modern one. The third is removing traditional material completely and transforming totally into modern materials. Third, traditional high quality noble houses are found in luxurious Korean restaurants and luxurious cafes while common houses are found in local food restaurant and cafes. It is because traditional common houses are still considered as low quality of design and it may prevent common houses from becoming high quality of design.

The purpose of this study was to investigate the natural ventilation methods using stack ventilation in offices. Natural ventilation is one of key factors to compose low energy and healthy buildings. Mechanical cooling and ventilation load can be dramatically reduced by natural ventilation and this is occurred by stack ventilation through solar chimney and atrium. The world famous sustainable office buildings to use stack ventilation were categorized into two types: “solar chimney” and “atrium”. The investigation shows that stack ventilation heavily relies on shading component and operable windows of exterior skin, precooling of intake air, location, height and materials of chimney and composition of atrium space. Finally, the space composition models for solar chimney and atrium are proposed based on the case analysis and the effectiveness of stack ventilation is verified by CFD simulation as the space composition is the basis for stack ventilation.

This research aims to analyze the small-medium size port competitiveness in the ASEAN-SAARC such as port of Leam Chabang in Thailand, port of Klang in Malaysia, port of Manila in Philippines, port of Ho Chi Minh City in Vietnam, port of Tanjung Priok in Indonesia, port of Colombo in Sri Lanka and port of Jawaharlal Nehru in India for establishing investment direction of Korea. ASEAN-SAARC is significant place in that it can be an economic diversification region to overcome Korea’s export-dependent economic structure and an alternative to addressing political and security factors not only the hegemonic war between China and the U.S but also the trade war between Korea and Japan. This study is established by Entropy and TOPSIS for the evaluation of port competitiveness based on the six main factors such as port facility, port location, port productivity, port cost, port service and socioeconomic stability. The result showed that no. of sail to Busan new port is ranked the most important factor with 0.14230, the revenue of import and export is the second with 0.11870 and the third with 0.11624 is unloading fee. While the berth productivity with 0.00620 was the worst valueless factor, terminal area is the 16th with 0.01103 and the volume of container with 0.02331 is ranked the 15th. In TOPSIS analysis, port of Klang was ranked top port with 0.67979 while port of Manila with 0.16119 was the worst competitive port comparing with other ports in the ASEAN-SAARC. This study suggests that port of Ho Chi Minh City is the most valuable port for Korea's investment among ASEAN-SAARC ports because not only it has a comparative advantage in port location, port productivity, port cost and port service but also Vietnam is most important country with trade of Korea. Therefore Korea should consider the investment to the port of Ho Chi Mich City for the purpose of improving productivity in Busan new port and connectivity with Vietnam through expanding port facilities such as depth extension and unloading equipment.
