기존의 많은 연구에서 거래은행 수에 영향을 미치는 요인들을 파악하려는 시도들이 있어 왔다. 일반적으로 기업규모나 업력, 레버리지도, 신용도, 수익성, 연성예산제약, 혁신과 관련된 기밀유지 효과 등이 거래은행 수에 영향을 미칠 수 있는 기업의 특성들로 파악되고 있다. 이와 더불어 최근 거시 경제변수도 거래은행 수에 중요한 영향을 미칠 수 있음이 보고된 바 있다. 본 연구의 목적은 우리나라 기업의 대출거래은행 수에 대한 결정요인을 종합적으로 파악하는데 있다. 즉 앞서 언급한 개별 기업들의 특성들의 영향과 더불어 경기변동의 영향도 살펴보았다. 개별기업 특성변수들 각각의 영향에 대해서 기존의 해외논문의 결과와 대비하여 보고하였고, 이러한 결과가 우리나라 간접금융시장에서의 기업들의 자금조달 행태와 어떻게 연결되는지에 대해 살펴보았다. 경기변동의 영향에 대한 분석에서는 경기변동이 기업의 거래은행 수 결정에 있어서 중요한 요인으로 작용함을 발견하였다. 기업들은 거래은행 수 선택에 있어서 경기역행적인 행태를 보였는데, 경기확장기에는 적은 수의 은행과 거래관계를 유지하는 반면 경기수축기에는 보다 많은 수의 은행과 거래관계를 유지하는 것으로 나타났다. 이러한 현상은 기업규모에 따라 다르게 나타났는데, 중소기업의 경우에만 거래은행 수가 경기역행적인 행태를 보였고, 대기업의 경우에는 거래은행 수가 경기와 상관없이 안정적이었다. 또한 대안적인 자금조달 수단에 접근이 상대적으로 어려운 비상장기업, 비재벌기업, 신용도가 낮은 기업에서도 경기역행적인 현상이 동일하게 나타났다. 시장의 경쟁도 측면에서는 경쟁적인 시장에서만 경기역행적인 특징을 보였고, 비경쟁적인 시장에서는 이러한 현상이 관찰되지 않았다.

이 글은 외환위기 이후 지방은행이 퇴출된 인천경기지역과 대전충남지역에서 지역중소기업의 주거래은행관계가 어떻게 변화하고 있는지를 검토하고 있다. 분석결과를 보면 전국은행은 지역의 중소기업과 주거래관계를 맺는데 주저하고 있으며, 전국은행의 주거래기업은 비교적 다수의 은행과 거래관계를 맺고 있다. 외환위기 이후 뚜렷해진 이러한 경향은 주거래기업의 종업원 규모별 현황에서도 확인되는데, 전국은행의 주거래기업은 비교적 규모가 크다. 이러한 가운데 기업은행과 국민은행이 지역중소기업의 주거래은행으로서 중요한 역할을 하고 있다. 전국은행은 윌리암슨형 조직적 불경제에 기인하여 관계적 금융을 취급하기 곤란하다. 지역금융문제를 완화하기 위해 서민금융기관의 적극적인 역할이 기대되고 있다.

Siberian flying squirrel, an endangered species in South Korea, is distributed through major mountain regions of South Korea. The number of Siberian flying squirrel(Pteromys volans) in South Korea has decreased and their habitats are fragmented and isolated because of anthropogenic activities. So far no molecular genetic data has, however, been available for their conservation and management. To obtain better information concerning genetic diversity and phylogenetic relationships of the Siberian flying squirrel in South Korea, we examined 14 individuals from South Korea, 7 individuals from Russia, and 5 individuals from northeastern China along with previously published 29 haplotypes for 1,140 bp of the mtDNA cytochrome b gene. The 14 new individuals from South Korea had 7 haplotypes which were not observed in the regions of Russia and Hokkaido. The level of genetic diversity(0.616%) in the South Korean population was lower than that in eastern Russia(0.950%). The geographical distribution of mtDNA haplotypes and reduced median network confirmed that there are three major lineages of Siberian flying squirrel, occupying; Far Eastern, northern Eurasia, and the island of Hokkaido. The South Korean population only slightly distinct from the Eurasia, and eastern Russian population, and is part of the lineage Far Eastern. Based on these, we suggest that the South Korean population could be considered to belong to one partial ESU(Far Eastern) of three partial ESUs but a different management unit. However, the conservation priorities should be reconfirmed by nuclear genetic marker and ecological data.

A "task network" is a type of social network that consists of experts who exchange professional help and advice regarding executing tasks. In this study, we investigate the task network used within the IS department of a national bank in Korea. We identify how this network moderates the influence of computer-mediated communication (CMC) technology on an individual s task performance. Size, density, and centrality were measured as the characteristics of a personal task networks. Size equates to the total number of colleagues who work with a specific member for a certain project. Density is the ratio of the number of actual relationships to the total number of available relationships. Centrality defines whether an individual s position is in the exact center of whole network, and is measured by betweenness centrality, meaning the position one member holds between others in a network. Our findings conclude that the conditions - the larger the size of the task network, the smaller its density and the higher its level of centrality - lead to more benefits of using CMC media. Further, this positive effect of CMC is more noticeable when it provides synchronicity.

COVID-19 pandemic has made the economy in Indonesia sluggish, especially Small and Medium Enterprises (SMEs). Simultaneously, the SMEs existence in Indonesia is fundamental and considered important by the government since it is able to assist numerous laborers and become an income source for the lower and middle classes of the community. The productivity of SME in a region will undeniably influence the availability of job and, of course, reduce the number of unemployed. Therefore, in this study, the researchers looked at how to improve SMEs performance to continue to exist amid the COVID-19 pandemic, by identifying the relationships between product characteristics, market competitive strategies, and the performance of SMEs. The research was done on SMEs in West Java, Indonesia. The example employed was Batik SMEs in Cirebon with at least 10 years in existence, and the total number of these SMEs was 165. As the basis of a quantitative approach, this study employed survey instruments by distributing a questionnaire. In analyzing the data, it utilized the structural equation modeling (SEM). The result showed a significant relationship between Product Characteristics, Market Competitive Strategy, and Price and Product Success Rate on SMEs Performance. This study's findings contribute to the SMEs performance literature.

This study tried to identify the job stress characteristics of female bank workers and the relationship between their stress and symptoms associated with musculoskeletal disorders(MSDs). The total number of 587 female bank tellers have been participated in this study. Specifically, questionnaire surveys regarding job stress and MSDs symptoms were conducted. On the basis of the results from the survey using Korean version of job stress questionnaire with 24 questions, stress scores associated with job requirement and job flexibility were relatively high. The job stress levels regarding job demand, organizational system, occupational climate at the work place were relatively high for the full time workers while the job stress levels regarding insufficient job control, job stability, interpersonal conflict, lack of reward were relatively high for the part time worker. The workers with longer total work years had relatively high job stress associated with interpersonal conflict, and organizational system while the workers with longer work years at the current job had relatively high job stress associated with occupational climate. Also, the workers with longer working hours a day had relatively high job stress associated with job demand, interpersonal conflict, organizational system, and occupational climate. According to the relationship identified in this study, symptoms at the neck, shoulder, hand, low back. leg were associated with the stress levels in terms of job flexibility, interpersonal conflict, job requirement, job stability. In conclusion, female bank workers are exposed to job stress due to their specific job characteristics and there has been certain relationships between their job stress and MSDs symptoms.

Global construction and engineering consulting (E&C) firms are actively seeking entry into overseas markets based on loan projects from multilateral development banks to provide a basis for entry into overseas markets and sustainable growth. Bids on these projects are competitive between global top firms in terms of the technical level and price due to the limited number of projects; thus, developing a successful partnership to complement competence has become an essential element to win bids. In this regard, many studies have analyzed enterprises through characteristic analyses or the derivation of influential factors from the past social networks based on social network analysis (SNA). However, few studies have been conducted to reflect the process of changes to analyze collaborative relationships. Thus, this study aims to identify dynamic changes in past social networks and develop a model that can predict changes in the relationships between E&C firms based on similarities or differences between firms, presenting a methodology to target firms for appropriate collaboration. The analysis results demonstrate that the sensitivity of the developed prediction model was 70.26%, which could accurately predict 163 out of 232 actual cooperative cases.

We examine the effects of the sustainability report (SURE) and investment decision on share price (SPRC). Explore whether the sustainability report changes the value-relevance of financial accounting variables indirectly. It is evident that the number of banks is only 12, which are all banks in Saudi Arabia, and we have included all of them in the final sample. Moreover, the same number of banks applied for the analysis concerning the accounting variables. This article utilizes a panel dataset from a sample of Saudis registered banks from the first quarter of 2014 to the last quarter of 2018. We utilize a balanced sample that contains all banks listed in Tadawul, 240 observations. Run GLM regression to tests the relationships. Findings exhibit that investors value the complementary disclosure of accounting information provided in SURE, and this disclosure produces a positive effect on SPRC. The SURE figure is robustly significant, suggesting that the market assigns a positive-significant correlation to the further information in the SURE. The indirect effects show that BPS×SURE is a positive-significant effect on SPRC, whereas EPS×SURE is positively-insignificant. The analysis shows that SURE's value relevance conforms through Saudis Banks, consistent with the hypothesis that diverse institutional perspectives probably influence the value-relevance of SURE.

To develop a natural re-seeding technology, the optimum soil incorporation time of Chinese milk vetch(CMV) plant residues, seed persistence in soil, biomass production and subsequent rice yield were determined from 2005 to 2007 in rice with CMV green manure in southern Korea. Generally, insufficient seedling stand was regenerated with CMV incorporation to the soil at 20 and 25 days after flowering(DAF), while high regeneration of greater than 400 seedlings per $m^2$ was observed at 35 and 40 DAF. High re-seeding stand of CMV incorporated at 35 DAF or later was related with high seed viability and heavy seed weight. Appreciable number of CMV seeds remained 4 month after burial in soil and a good number of CMV seedlings regenerated from this seed bank at rice harvest time in the fall. Based on the relationships among re-seeding number of CMV plants, seed weight and seed viability, CMV plants should be incorporated into the soil 35 DAF(May 30) or later when CMV seeds were sufficiently matured. The natural re-seeding stand for the 3-year trials was stable ranging from 437 to 700 plants per $m^2$ and the biomass production was sufficient to supply nitrogen for rice growth. The use of re-seeding CMV plant can produce similar rice yield like that of rice without CMV green manure.
