본 연구는 기업의 부채만기와 결정요인의 관련성에 대한 이론적 논거를 제시하고 우리나라 상장제조기업을 대상으로 대기업과 중소기업으로 구분하여 기업규모별 부채만기 결정요인을 다중회귀분석으로 실증적으로 규명하고자 하였다. 실증적 분석 대상기간은 1995년부터 2000년까지 6개년으로 분석기간 동안 신용평가 전문기관으로부터 회사채 신용등급을 평가받은 제조기업 204개 기업을 표본으로 선정하여 분석하였다. 연구결과를 종합하면 우리나라 상장제조기업으로 대기업과 중소기업 모두 기업규모가 크고 레버리지가 높고 자산의 만기가 긴 고정자산을 많이 보유하고 있는 기업일수록 부채만기구조에서 장기부채를 많이 이용하고 있는 것으로 입증되었다. 성장옵션과 법인세율은 부채만기결정에 영향을 미치지 못하는 것으로 나타났으며 기업의 우량성과 유동성위험을 나타내는 수익증가율과 채권등급은 대기업의 주요 부채만기 결정요인으로 나타났다. 수익증가율이 크고 채권신용등급이 높은 우량대기업일수록 단기부채를 많이 이용하는 것으로 확인되었으며 중소기업은 기업의 우량성과 신용등급이 부채만기에 유의적인 영향을 미치지 않았다.

This study analyzes determinants of bond returns in terms of systematic risk versus idiosyncratic risk by examining relationship among those factors. First we examined the cross-sectional determinants of corporate bond returns with Korean bond market data from 2001 to 2014. This paper uses term factor and default factor for systematic risk, and duration factor and credit rating factor for idiosyncratic risk. The empirical result shows that systematic risk can explain cross-sectional differences of bond returns rather than idiosyncratic risk which is the same result in advanced markets(US or Europe). This result is different from the previous Korean studies which showed that idiosyncratic risk is more important than systematic risk in Korean bond market. The reason for the different result may be the longer sample period which includes the most recent period. It is insisted that Korean bond market is getting more synchronized with the advanced bond market. In conclusion, this empirical result implies that Korean bond portfolio managers should focus on systematic risk, which is contrary to current system in Korean asset management industry.

A reasonable process for the activity duration estimation is required for the successful construction management because it directly affects the entire construction duration and budget. However, the activity duration is being generally estimated by the experience of the construction manager. This study suggests an estimation model of construction activity duration using neural network theory. This model estimates the activity duration by considering both the quantitative and qualitative elements, and the model is verified by a case study. Because the suggested model estimates the activity duration by a reasonable schedule plan, it is expected to reduce the error between planning duration and actual duration in a construction project.

일국(一國)의 경제발전(經濟發展)은 경제적 진보와 근대화를 수반하는 역사적 현상이지만 구체적으로는 산업구조(産業構造)의 변화(變化)에 의한 생산(生産)과 소득(所得)의 증가(增加)라는 측면을 가지고 있다. 한국과 일본의 경제발전과정에 수반되는 경제성장과 산업구조변화에 대한 요인을 비교 분석하는 것은 양국경제의 발전현상을 이해하고, 향후의 경제정책에 기초적인 정보를 제공할 수 있다는 점에서 그 중요성이 있을 것이다. 따라서 본고는 "비례적(比例的) 성장(成長)으로부터의 편차(偏差)(DPG)" 방법을 일본의 경우는 1915~90년, 한국은 1960~90년까지의 장기적인 산업연관자료에 적용하여 양국의 산업성장과 산업생산구조변화에 대한 요인을 수요측면에서 비교 분석하였는바, 그 결과는 다음과 같이 요약된다. 우선 양국경제의 산업생산구조 및 주도산업의 변화는 시기에 있어서 차이를 보이지만 분석기간중 양국 모두에서 농림수산업은 계속해서 생산비중이 줄어들고 있고, 경제성장을 주도한 산업이 경공업에서 중화학공업으로, 그리고 중화학공업에서도 중공업으로 이전된 것으로 나타났다. 일본의 경우는 1970년대에는 생산자서비스부문을 중심으로, 그리고 1980년대에는 소비자서비스부문을 중심으로 "경제의 서비스화"가 진전되어 서비스산업이 주도산업으로 부상되고 있으나, 한국경제에서는 1990년까지도 서비스산업의 확대가 관측되지 않고 있다. 이러한 결과는 향후 한국경제의 산업생산구조에 있어서 서비스산업의 중요성이 점차 커질 것이며, 특히 "경제의 서비스화"가 생산자서비스부문을 중심으로 이루어질 가능성이 높다는 것을 시사한다. 한편 양국의 성장패턴을 살펴보면, 일본의 경우는 시기별로 성장요인에 많은 변화가 있었으나 대체로 수출보다는 국내수요(國內需要)가 경제성장에 중요한 역할을 한 것으로 나타났다. 그러나 한국경제의 성장의 성장에는 수출과 투자의 역할이 중요했으며, 특히 수출은 분석기간중 지속적으로 정(正)의 효과(效果)만을 보여 경제성장의 견인차역할을 한 것으로 나타났다. 1980년대까지 한국경제의 성장에 있어서는 수입대체보다는 수출확대를 통한 중화학공업의 육성이 지대한 영향을 미쳤으며, 이러한 수출주도적인 중화학공업의 성장패턴은 현재 국내수요(國內需要)의 규모(規模)와 산업구조변화를 일본의 경우에 비추어볼 때, 향후 몇 년 동안은 크게 변화하지 않을 것으로 판단된다.

This study purposed to analyze the determinants of length of stay for patients having alzheimer dementia in geriatric hospitals. Sample data was collected from the National Patient Sample (NPS) produced by the Health Insurance Review & Assessment Service (HIRA) in 2009. Total 538 alzheimer inpatients over 65 years were used in the analysis. Patients were classified into 5 risk groups to represent the case-mix differences of patients. Organizational characteristics of geriatric hospitals such as number of beds, doctors, and nurses were included in the analysis model. In multivariate regression analysis, hospital variables were not statistically significant in explaining the length of stay. Two risk group were statistically significant in analysis, However, their signs of relationship with the dependent variable were opposite to the expectations. These results suggest that the characteristics of patients and hospitals did not have impacts on the length of stay. There will be needs to test the effects of other factor such as social needs which represents the socio-economic status of the family for the patients.

This study examines determinants of user immersion for Korean drama and entertainment genre programs among Chinese students in Korea. The major results are as follows: firstly, user immersion for entertainment genre was more greater than that of drama genre. Although drama was tended to evaluated based on star appearance and narrative structure, entertainment program was favored by its pleasure and vividness. Secondly, there were gender differences for entertainment and drama genre programs between male and female respondents. Also, there was a correlation between drama immersion and duration of stay. Thirdly, although determinants of drama immersion were program characteristics, duration of stay and drama preference, those of entertainment immersion were program characteristics, appearance of star players and entertainment preference.

The purpose of this paper is to examine the factors that encouraged the industrial growth of Koran city gas industry during 1995-2009, by carrying out input-output structural decomposition analysis(IO-SDA) using Syrquin's model. The results show that the main factors which contributed to the growth of the Korean city gas industry are final domestic demand(48.4%) and technological change(38.6%). By examining the results for the three periods of 1995-2000, 2000-2005, and 2005-2009, the tendency of changes between the two main factors is drawn. In contrast to the drastic decreasing tendency of the final domestic demand's contribution to the growth, 84.5%, 18.9%, and 15.4%, respectively for each period, there is an increasing tendency for technological change as seen by the results of 7.4%, 70.0%, and 42.2%, respectively. These findings may be a result from the fact that the rate of gas supply in the residential sector has been saturated recently. They are also reflective of the energy consumption trend of industrial activities as there has been a shift in the approach for supplying energy, from the traditional approach which use fossil fuels to the newer approach which uses environmentally friendly energy sources. For the continued growth of the city gas industry, policymakers sould consider greater investment in the expansion of city gas supply infrastructure for industrial activities rather than for the residential sector.

This study aimed to examine the predictors of mental health confidence(MHC) among individuals in psychiatric long-term care facilities(PLCF). It further examined whether the predictors and underlying mechanisms differed by the length of hospitalization. Sample consisted of 1,742 individuals residing in PLCF who participated in the Survey on PLCF. Structural equational modeling was used to examine the predictors of MHC. Multi-group Structural Equation Modeling(SEM) was used to examine whether the predictors and mechanisms differed by the length of hospitalization between those of 10 years or less (n=962) and 10 years and more (n=780). Major findings were as follows. (1) Education, duration of mental illness, and psychiatric symptoms were significantly related to MHC. (2) Duration of mental illness presented significant indirect effects on MHC via its effects on perceived stigma. (3) The predictors and underlying mechanisms differed by the length of hospitalization. Based on the findings, implications and limitations of the research were discussed.
