The goal of this study is to summarize the various dependant variables that the learning organization affects and compare their effect sizes to those of corporate employees. To achieve the purpose, a total of 30 journals and doctoral dissertations were strictly analyzed based on the comprehensive meta analysis 3.0 program. The results are as follows: First, there are a total of 9 organization-related variables and 9 individual-related variables resulting from learning organization and learning organization has been identified to have a positive correlation with all dependant variables. Second, among the organization-related variables, the biggest effect size was job satisfaction which was used to analyse the relationship with learning organization. Third, the biggest effect size of individual-related variables was identified as knowledge creation which was investigated to figure out the relationship with empowerment set by the learning organization’s sub-variable. Based on the results, the study’s findings suggest some implications. First, meta analysis should be required between learning organization and other dependant variables in different occupational groups. Second, comparative analysis of domestic and foreign employees should be needed by using meta analysis that synthesizes domestic and foreign research. Third, an analysis of research trends that can identify the overall research flows of the learning organization and systematic literature review that nominates the dependant variables of the learning organization should be carried out. Fourth, it is necessary to find out additional statistical method to perform publication bias verification even if there are less than three advance researches that have analyzed the relationship between the same variables.

Kangseok Seo,Jeongmi Seo,Jiyoun Yeun,Haebin Choi,Young-In Kim,장선영 대한약학회 2021 Archives of Pharmacal Research Vol.44 No.4

The intestinal mucosa is continuously exposedto a large number of commensal or pathogenic microbiotaand foreign food antigens. The intestinal epithelium formsa dynamic physicochemical barrier to maintain immunehomeostasis. To effi ciently absorb nutrients from food, theepithelium in the small intestine has thin, permeable layersspread over a vast surface area. Epithelial cells are renewedfrom the crypt toward the villi, accompanying epithelial celldeath and shedding, to control bacterial colonization. Tightjunction and adherens junction proteins provide epithelialcell–cell integrity. Microbial signals are recognized by epithelialcells via toll-like receptors. Environmental signalsfrom short-chain fatty acids derived from commensal microbiotametabolites, aryl hydrocarbon receptors, and hypoxiainducedfactors fortify gut barrier function. Here we summarizerecent fi ndings regarding various environmental factorsfor gut barrier function. Further, we discuss the role of gutbarriers in the pathogenesis of human intestinal disease andthe challenges of therapeutic strategies targeting gut barrierrestoration.

최근 화석연료 고갈과 이상기후 변화 발생 등 환경문제로 인하여 전 세계적으로 탄소중립에 대한 관심이 증대됨에 따라 재생에너지에 대한 관심도 고조되고 있다. 특히 국내의 경우 그린뉴딜을 앞세운 탄소중립 정책과 ESG(Environmental, social and Governance)에 대한 관심이 증대되면서 태양광 산업이 제2의 전성기를 맞이할 것으로 기대하고 있다. 따라서 본 연구는 이러한 태양광 산업의 최근 15년 동안의 국내 기술 특허들을 분석함으로써 태양광 기술의 발전 변화와 동향을 파악하고자 한다. 특히 본 연구는 국내 중소기업의 태양광 기술 특허를 활용하여 특허 인용 네트워크 분석을 실시하여, 특허 분석에서 소외되던 국내 중소기업의 기술 발전과 현황을 체계적으로 분석함으로써 향후 태양광 산업에서 중소기업의 발전 방향을 제시하고자 하였다. 이를 위하여 WIPSON을 통해 국내 태양광 기술 특허 데이터를 수집하였고, 데이터 정제를 위하여 Python3.6과 네트워크 분석을 위해 Gephi 9.2.0을 활용하였다. 분석 결과 태양광 산업에서 다양한 융ㆍ복합이 이루어지고 있음 발견하였다. 국내 태양광 산업의 특허 출원 건수가 감소함에 따라 태양광 산업이 쇠퇴기에 접어들었다는 진단을 내리는 연구가 있으나, IPC 특허 인용 네트워크 분석결과 태양광 기술 특허의 중심성이 기초기술에서 응용기술로 넘어가고 다양한 IPC가 나타나고 있는 점을 확인할 때 아직 성장ㆍ성숙기에 머물고 있을 것으로 판단된다. 따라서 태양광 산업은 융복합 확산 단계에 위치하기 때문에 이에 대한 정책적 지원 마련이 필요하다. In recent years, as interest in carbon neutrality has increased worldwide due to environmental problems such as fossil fuel depletion and abnormal climate change, interest in renewable energy is also increasing. In particular, in Korea, the photovoltaic industry is expected to face its second heyday as interest in carbon neutrality policies and ESG with the Green New Deal at the forefront increases. Therefore, this study aims to understand the changes and trends in photovoltaic technology development by analyzing patents in the photovoltaic industry over the past 15 years. In particular, this study attempted to present the future direction of development of SMEs in the photovoltaic industry by systematically analyzing the technological development and current status of SMEs that were alienated from patent analysis. To this end, patent data was collected through WIPSON, and Python 3.6 was used for data purification and Gephi 9.2.0 was used for network analysis. As a result of the analysis, it could be observed that the photovoltaic technology of domestic SMEs is changing from basic technology to application technology over time.

( He Luzhu ),( Sirelkhtem Eltayeb Elfaki ),( Jung Hye Hwang ),( Soo Jeung Choi ),( Hayun Kim ),( Haebin Lm ),( Dongwoon Han ) 한국모자보건학회 2016 한국모자보건학회 학술대회 연제집 Vol.2016 No.2

Background The indices of maternal mortality and morbidity in Sudan are among the highest globally, meanwhile poor utilization of antenatal care (ANG) services are reported. Antenatal care services are key maternal health services that can significantly reduce maternal mortality. However, much less is known about the factors associated with utilization of ANG services in rural areas of Sudan. Aim To assess quality of ANG services and identify the factors associated with low prevalence of antenatal care services among reproductive age women in rural Sudan. Method: A cross-sectional study was conducted in four primary health centers in Marawi, Northern Sudan from October to November 2015. The questionnaire was developed with 4 sections, including 3 on independent variables (knowledge of pregnancy, accessibility, socio-demographic), and the dependent variable was utilization of ANG services. Data were collected through face to face interview survey and then coded and analyzed with Excel and SPSS software. Chi-square and logistic regression were used to determine the association between dependent and independent variables. Results 348 women were approached during the survey, only 163 (46.8%) women made four or more ANG visits. Most of them (over 80%) had good knowledge about danger signs and information of pregnancy. ‘Transport cost is high” was the most (56.8%) reported barrier to utilizing ANG services, following answers were “Health center is far” and “Husband refusing” . Distance form home to health center and health services waiting time were significantly related to number of ANG visits. Many socio-demographic characters such as marital status and education level of women or husbands were factors influencing the utilization of ANG services Conclusion Utilization of ANG visits was low in Marawi District. The women living there had good knowledge about pregnancy, however, had several barriers to access the ANG services in health center. Thus, public health intervention programs should be targeted towards improving the pattern of antenatal care use among the reproductive age women in Sudan.
