본 연구는 국내 상장시장 간 원가의 비대칭성의 차이가 있는지, 상장기업의 기업 규모에 따라 원가의 비대칭성이 차이가 있는지 검증하였다. 기존의 연구에서는 상장기업만을 대상으로 한 원가의 비대칭성은 살펴보았지만, 상장기업 간의 규모의 차이는 살펴보지 않았다. 그러나 다수의 연구에 따르면 상장시장 간 또는 상장기업이라 할지라도 기업의 특성이나 기업고유의 위험(firm risk)이 서로 다르기 때문에 이와 같은 영향이 기업 내부 자원배분 의사결정에 미치는 영향에 차이가 있을 것이라고 보고 분석을 실시하였다. 이를 위해 2011년부터 2019년까지 유가증권시장과 코스닥시장을 대상으로 Anderson et al.(2003)의 원가행태 모형을 이용하여 분석한 결과, 유가증권시장과 코스닥시장의 원가행태는 차이가 있는 것으로 나타났다. 전반적으로 선행연구와 마찬가지로 원가의 하방경직성이 보고되었으나 유가증권시장의 경우 원가의 하방경직성이 완화됨을 확인할 수 있었다. 기업규모가 클수록 매출액이 감소할 때 유휴자원의 처분의사결정이 더 뚜렷한 것으로 나타났다. 추가적으로 외국인투자자 지분율이 높은 경우, 유가증권시장일수록, 기업규모가 클수록 원가의 하방경직성의 완화는 더 크게 나타남을 관찰할 수 있었다. 본 연구는 원가의 비대칭성에 관한 연구를 확장하고 상장시장 간, 기업규모 간의 차이가 존재함을 밝힌 연구로써 선행 연구와의 차별성을 갖는다.

This paper proposes the concept and the general framework of the risk-based seismic design. Because earthquakes and the behaviors of structures are very unpredictable, probabilistic seismic design methods have been proposed after deterministic design methods. Considering these changes, we can find that the important point of seismic design is not the structural behavior itself, but the consequence of structural behavior under possible earthquakes. Risk-based seismic design can tell these consequences under any earthquakes. In this paper, structural confidences are considered by using fragility curve, and risk is modeled by failure probability and consequence-property damage cost, casualty cost.

The cost-benefit analysis is a technique for assisting with decision about the use of society's scare resources. There exists no detailed assessment like cost-benefit analysis. But recently, many policy analysts criticized the merit of cost-benefit analysis. As it is, it can be said that partial or approximate estimates of benefit and cost may be more dangerous than helpful. The purpose of this study is to overcome the limit of traditional cost-benefit analysis. For this purpose, we use the system dynamics approach for setting up new cost-benefit analysis, which we named that ‘Dynamics Cost-Benefit Analysis'. The usefulness of ‘Dynamics Cost-Benefit Analysis' is as follows; finding structural causal relationship between cost factors and benefit factors, understanding the long-term behavior of systems economic feasibility. In this study, we apply 'Dynamic Cost-Benefit Analysis' to case that is construction investment of funeral house by local government sector.

염해에 따라 발생하는 보수시기와 보수로 유지되는 내구수명은 보수비용 평가에 매우 중요한 요소이다. 일반적으로 사용하는 결정론적 보수비용 평가는 사용기간의 연장에 따라 계단식으로 증가하게 되며, 보수로 인해 변동되는 내구수명의 변화를 고려하지 못한다. 본 연구에서는 확률론적인 보수시기 및 비용을 평가하기 위해, 염해에 노출된 콘크리트 교각을 선정하였다. 두 가지 배합과 염화물에 노출된 외부 환경조건을 고려하여 염화물 거동을 평가하였으며, 도출된 내구수명과 수명에 대한 확률변수를 변화시키면서 보수시기 및 비용 변화를 분석하였다. 변동계수의 변화에 따른 보수회수는 큰 차이가 발생하지 않았으나, 초기의 내구수명 연장이 구조물의 보수시기 및 비용에 큰 영향을 미치고 있었다. 또한 확률론적 보수비용 산정 모델은 결정론적 모델과 다르게 연속적인 보수비용이 평가되므로 목표내구수명에 따라 보수회수를 감소시킬 수 있는 효과적인 기법임을 규명되었다.

Recently, the researches to explain Switching Behavior through Theory of Planned Behavior have been discovered. Many researches say that System factors of mobile telecommunication service(MTS) is positively associated with Switching Intention. But There is no difference of system factors between mobile telecommunication services because of IT technique Development. Thus, this study investigated whether switching cost and alternative's attractiveness influence switching intention concerning mobile telecommunication service by adopting Theory of Planned Behavior (TPB) as an underlying theoretical premise. The study also attempted to determine the moderating effects of personal innovativeness on switching intention. For these purposes the author has developed several hypotheses as follows: H-1. The switching cost of different MTS is associated with the attitude of MTS which is using. H-2. The switching cost of different MTS is associated with the subjective norm of MTS which is using. H-3. The switching cost of different MTS is associated with the perceived behavior control of MTS which is using. H-4. The alternative's attractiveness of different MTS is associated with the attitude of MTS which is using. H-5. The alternative's attractiveness of different MTS is associated with the subjective norm of MTS which is using. H-6. The alternative's attractiveness of different MTS is associated with the perceived behavior control of MTS which is using. H-7. The switching cost of different MTS is associated with the switching intention. H-8. The alternative's attractiveness of different MTS is associated with the switching intention. H-9. The attitude of MTS is associated with the switching intention. H-10. The subjective norm of MTS is associated with the switching intention. H-11. The perceived behavior control of MTS is associated with the switching intention. H-12. The personal innovativeness has been a moderating effects to switching intention. Data has been collected from 403 respondents for this study using a questionnaire method. The survey for the actual analysis of the research was done and analyzed with the customers who have an experience of using Mobile telecommunication service and the samples were selected among the middle and high school students who live in Seoul area, the university students who live in Seoul, Gyeonggi and Chungcheng Provinces, and the ordinary workers who are working in Seoul and Gyeonggi Province. The survey was done for 23 days from March 28, 2008 through April 12, 2008. The positive analysis was done with SPSS 12.0K statistics package and visual PLS program using the analysis techniques of frequency analysis, reliability analysis, correlation analysis and factor analysis. In addition, structural equation modeling was conducted using AMOS 5.0. The data was analyzed by frequency analysis using SPSS 12.0 and structural equation modeling using AMOS 5.0. The result of the overall model analysis is as follows: Chi-Square=378.306, d.f.=107, p-value=0.0, GFI=.904, AGFI= 0.863, IFI= 0.939, NFI= 0.917, RMSEA= 0.079, TLI= 0.922. The results of the overall model analysis were coherent. The following study results were revealed: First, switching cost was related positively to attitude, subjective norm and perceived behavior control, three components of TPB. Second, alternative's attractiveness was related negatively to subjective norm but positively to perceived behavior control. Third, switching cost and attitude was related negatively to switching intention, while perceived behavior control was related positively to switching intention. Finally, the study found the moderating effects of personal innovativeness on switching intention. Based on the results, the study offers marketing strategic implications for mobile telecommunication service industry.

This study was to explore purchasing behavior and repurchase intention by considering social-face sensitivity and conspicuous consumption. To do this, first, this study tried to explain how consumers had different characteristics for social-face sensitivity, conspicuous consumption, purchasing behavior, and repurchase intention for outdoor wear. Second, this study tested the relationship between consumer behavior (purchasing behavior and repurchase intention) and social-face sensitivity by considering the mediating effect of conspicuous consumption. As the results, first, there was a significant relationship between social-face sensitivity (sensitivity to saving face) and conspicuous consumption, which had a significant effect on the purchasing behavior with outdoor wear(purchase frequency, purchase cost). Second, social-face sensitivity (consciousness of shame) had a significant effect on conspicuous consumption (preference for famous brands, status symbol, pursuing fashion), and social face sensitivity (consciousness of social formality) had a significant effect on conspicuous consumption (preference for famous brands). The relationship between the conspicuous consumption and purchasing behavior showed that conspicuous consumption had significant effects on consumer behavior (purchase frequency, purchase cost). The relationship between the social-face sensitivity and purchasing behavior showed that being conscious of others had a significant effect on purchasing behavior. Third, purchasing behavior with outdoor wear had a significant effect on repurchase intention. Finally, this study confirmed that conspicuous consumption had a partially significant mediating effect on the relationship between social-face sensitivity (sensitivity to saving face) and purchasing behavior.

How health care providers compete and how competition among them affects their behavior are crucial questions in theory and health policy. In ordinary markets, competition improves social welfare, However in health care markets facing uncertainty and information asymmetry, competition can take the form of wasteful quality competition and result in cost increase. The purpose of this study is to examine the characteristics of hospital service markets and examine the impact of hospital competition on hospital behavior, more specifically hospital cost and the size of personnel. Based on patient discharge data of 2002 by the Ministry of Health and Welfare and Korea Institute for Health and Social Affairs, and health insurance EDI claims data of 2002, this study measures the degree of competition in the inpatient service market of hospitals, using variable radius method and Herfindahl index. The result of the study shows that the hospital service market consists of on average 3.13 government administrative units(shi, gun, or gu). Compared with hospitals, general or general specialized hospitals cover larger markets and operate in more competitive markets. Nearly 60% of patients use hospitals, which are not located in their government administrative units, meaning that market definition based on variable radius is better than the conventional method of market definition based on government administrative units. The results of multivariate analysis show that competition is not associated with high cost index of hospitals. But hospitals in more competitive markets employ larger(more intensive) input of personnel per 100 beds, implying that hospital competition in Korea can have the form of quality and cost-increasing competition.
