  • The geotectonics and geomorphic structure of Korea resulted from the Song-rim Disturbance and the Daebo orogenic movements. Afterward this mountainous peninsula underwent several geological changes on a small scale, and it was also claimed that the steady rising of the elevated peneplain of the eastern coast and the submerging of the southwestern coastal area are largely due to the tilted block movement. These views have been generally accepted good in several ways, but they are limited in range or lacking in theoretical integration. The present writer investigated the geology of the Mt. Chi-ri-san and the Honam coal mining area for a geological map in 1965, respectively. The results of these studies convinced the present writer that the conventional views, which were based upon a theory of lateral pressure should be reconsidered in many respects, and more recent studies made it clear that the morphological development in the southwestern area can be better explained by the orogenic movement and rock control. The measurement of submerging speed of the western coastal area (Pak. Y. A., 1969) and a new account on the geology and tectonics of the Mid-central region of South Korea (Kim O.J., 1970) act as an encouragement to a new explanation. The present writer's researches on the extreme southwestern portion of the peninsula show that the steady submerging of this area cannot be attributed to a simple downthrown block phenomenon caused by block movement. It is no more than the result of the differential movement of uplifting in the eastern and western coastal areas and the rising of sea-level in the post-glacial period. This phenomenon could be easily explained by the comparison of the rate of rise in sea-level and amount of heat flow between Korea and other areas in the world. The existance of the erosional planes in the Sobaik-San ranges also provide an evidence of an upheaval in the western coast area. Though the Sobaik-San ranges largely follow the direction of the Sinian system. They consist of the numerous branches, whose trends run more or less differently from their main trend because of the disharmonic folding, are converged into Mt. Sobaik-San and Chupungryung. The undulation of the land is not wholely caused by orogenic movements, where as the present writer confirmed that the diversity of morphological development is the direct reflection of geological conditions such as rocks and processes which constitute the basic elements of geomorphic structure. An east-west directed mountain range which could be named as Hansan mountain range, was claimed to be oriented by the joint control. The geological conditions such as a special erosion and weathering of agglomerate and breccia tuff usually produce pot-hole like submarine features which cause the whirling phenomenon at the southwestern coast channel.

  • Purpose - According to agency theory, managers have incentives to adjust firm revenues to meet earnings expectations or delay bad news disclosure because of performance-based compensation and their reputation in the market. When the bad news accumulates, stock prices fail to reflect all available information. Thus, market prices of stocks are higher than their intrinsic value. After all, bad news crosses the tipping point, it comes out all at once. That results in stock crashes. Auditors can decrease stock crash risk by reducing agency costs through their informational role. Especially, stock price crash risk is expected to be lower for firms adopting high-quality audits. We focus on distribution and service industry to examine the relation between audit quality and stock price crash risk. Industry specialization and auditor size are used as proxies for auditor quality. Research design, data and methodology - Our sample contains distribution and service industry firms listed in KOSPI and KOSDAQ during a period of 2004-2011. We use a logistic regression to test whether auditor quality influences crash risk. Auditor quality was measured by industry specialist auditor and Big4 / non-Big4 dichotomy. Following the approach in prior researches, we use firm-specific weekly returns to measure crash risk. Firms experiencing at least one stock price crash in a specific week during year are classified as the high risk group. Results - The result of analyzing 429 companies in distribution and service industry is summarized as follows: Above all, it is shown that higher audit quality has a significant negative(-) effect on the crash risk. Crash risk is alleviated for firms audited by industry specialist auditors and Big 4 audit firms. Therefore, our results show that hypotheses are supported. Conclusions - This study is very meaningful as the first study which investigated the effects of high audit quality on stock price crash risk. We provide evidence that high-quality auditors reduce stock price crash risk. Our finding implies that the risk of extreme losses can be reduced through screening of high-quality auditors. Therefore investors and regulators may utilize our findings in their investment and rule making decisions.

  • 본 연구는 형사책임과 관련성이 있다고 생각되는 일치추론이론과 외부귀인이론 등을 통해 도의적 책임판단에 관한 범죄심리학적 이론을 연구하여 미국에서 배심원이 유무죄의 평결을 도출해 내는 판단과정에 관한 이론적 관점들을 접근하고자 한다. 정신장애(insanity)는 형사책임능력에 관한 법적인 개념이며 임상적인 혹은 정신의학적인 개념이 아니다. 따라서 법체계가 다르면 정신장애의 정의도 달라지게 마련이다. 우리나 라 법과 미국의 법은 서로 매우 다른 체계를 가지고 있어서 미국법의 개념들이 한국법의 개념들과 불일치하는 경우가 매우 많은데, 형사책임능력에 관한 법이론적 개념들이 그 대표적인 예라고 할 수 있다. 우리나라의 형법은 심신상실(형사책임무능력)과 심신미약(한정책임능력)을 구분함으로 미국이나 영국에서 이용되는 정신장애의 개념이 직접 적용되지 않는다. 그럼에도 불구하고 최근에 들어 한국에서도 미국의 법에서 사용되는 정신장애의 개념에 대한 관심이 높아지고 있고, 형사책임의 법적판단에 임상적인 자료 및 전문가 의견이 큰 비중으로 고려되고 있으므로 법학과 심리과학(학문적 글로벌 개념)과 사이에 상호간 진지한 논의와 협력이 요구된다. 한국에서의 정신장애에 대한 정의와 구체적 기준들은 한국 형법의 전반적인 이론적 맥락에서 구축되어야 함은 분명한 것으로 사료된다. 그러나 그러한 조작정의가 객관적 진실을 전혀 도외시한 것이어서는 안된다고 사료되며, 따라서 이 문제에 관하여 실증적인 경험학문을 지향하는 심리학이나 정신의학 등의 행동과학과의 적극적인 협력이 절실히 요구된다.

  • Metabolic syndrome is a cluster of metabolic risk factors associated with increased risk of cardiovascular diseases. Recently, the prevalence of metabolic syndrome has increased in Korea. The aim of this study was to develop a Healthy Han-sik Nutrition Education Program (HHNEP) based on commonly recognized Korean foods in order to decrease metabolic syndrome risks. The target population of the HHNEP is adults with metabolic risk factors. The initial version of the HHNEP was developed based on a review of literature and various dietary guidelines by expert committees as well as the results of a survey on the perception of common Korean dishes and foods as Han-sik. The focus group discussion conducted of nine participants from the target population. After minor modification, the final version was developed. The contents included five sections: 1) aims, 2) introduction of Korean Food Guidance System, 3) cholesterol contents in food, 4) menu planning method using Han-sik, and 5) examples of daily Han-sik menu. The Han-sik list was selected based on the results from a Han-sik perception answered by 35 Korean adults aged 30-60 years using 517 frequently consumed Korean foods from the fourth Korea National Health and Nutrition Examination Survey. The nutrition education program was developed based on scientific evidence for the prevention of metabolic syndrome and focuses on tailoring education to an individual's dietary problems. Educational method was developed by a group of expert committees based in planned behavior theory and related research results. The education method consisted of assessment of current diet, four face-to-face nutrition education sessions over 8 weeks, and evaluation after 8 and 16 weeks. Initial version of nutrition education materials and methods was tested for feasibility by a select group of nine Korean healthy adults. Successful implementation of the program would include application by nutritional professionals at the health promotion center of the hospitals, public health center, and work sites. Intervention studies are needed to evaluate the feasibility and effectiveness of this program before large-scale applications.

  • Objective : The concept of Eum-Fire(陰火), which was brought up by Li Dong-yuan(李東垣), is such a very ambiguous thing that many medical scholars had tried to understand its real meaning. Trying to understand the real concept of Eum-Fire, this study goes on based on the view that the concept of Eum-Fire in the medical books of Li Dong-yuan was used as being the same thing with the concept of Xim-Fire(心火) and Premier-Fire (相火), and the substance of this kind of fire is the fire in Ximpo(心包) and Myungmun (命門) which works in the system of Ximgye(心系). To verify this view is the main objective of this study. Method : Inquiring into Li Dong-yuan's medical books, this study investigated examples of the uses of the terms of Eum-Fire, Xim-Fire and Premier-Fire, and analyzed the relation between the meanings of these terms. And as a collateral evidence to the main view of this study, this study notes Wang An-dao(王安道)'s reference about Eum-Fire and inquires into the concept of Premier-Fire that was formed by Liu He-jian(劉河間), who had been referred to in Wang An-dao's argument about Eum-Fire. And this study also presents the Chen Shi-duo(陳士鐸)'s view about Eum-Fire that is expected to show a more concrete concept of Eum-Fire than now and seems to deserve to be compared with that of Li Dong-yuan. Result and Conclusion : It could be understood that the concept of Eum-Fire in Li Dong-yuan's books was used as a thing that owns the same substance as a kind of fire with Xim-Fire and Premier-Fire. In this viewpoint it could also be understood that Li Dong-yuan had attached the concepts like Xim-Fire and Eum-Fire to the concept of Premier-Fire, so terms like these could be understood as such concepts that represented the diverse figures of Premier-Fire. And this study also found that the substance of Xim-Fire as a kind of Premier-Fire means the fire of Ximpo and Myungmun that works in the system of Ximgye, which seems to be formerly introduced as a frame of Premier-Fire by Liu He-jian. This study also found the indirect basis of this viewpoint in the books of Chen Shi-duo, and could get a conclusion that Chen Shi-duo's view about Eum-Fire can be regarded as a thing that could show us more concrete matter of Eum-Fire than now.

  • Purpose - The ultimate goal of a franchise system comes from its win-win strategy. Agency theory uses goal incongruity to examine complex contracting problems between buyers and suppliers. Goal incongruity within a contractual relationship can be defined as the agent's desire not to cooperate. It is the degree to which the contractual terms do not satisfy the agent's goals. The greater the goal incongruity between the agent and the contract, the more likely it is that the agent will meet the terms of the contract. Thus, goal incongruity between buyers and suppliers has close relationships with both behavioral and financial performance. This study tries to examine these relationships in the franchise context using a model including related variables, such as regulatory foci, financial performance, and opportunism, to explain the reasons that not all franchisees perform their best. In particular, the study examines the effects of goal incongruity on regulatory focus, and the effects of regulatory focus on performance and opportunism. In short, the objective is to determine goal incongruity's effect on regulatory foci, and the effect of regulatory focus on performance and opportunism. Research design, data, and methodology - This study used data collected from the franchisee managers of 104 franchisors in South Korea. The franchisors include more than 10 franchisees, the majority of whom have been in business for more than five years. The study also surveyed 104 franchisees, matched with their franchisors for the sake of a dyadic approach. The study used regression analysis to test the hypotheses. Results - H1 and H2 predicted that goal incongruity would decrease promotion focus and increase prevention focus. Supporting H1, the result indicates goal incongruity had a positive effect on promotion focus. However, H2 was not supported. Goal incongruity had no significant effect on prevention focus (β = -.375, t = -4.331 and β = -.145, t = -1.950, respectively). H3 and H4 predicted that promotion focus would increase financial performance and decrease opportunism. Supporting these hypotheses, the results indicate that promotion focus had a positive effect on financial performance and a negative effect on opportunism (β = .771, t = 7.899 and β = -.765, t = -6.778, respectively). H5 and H6 predicted that prevention focus would decrease financial performance and increase opportunism. However, the results do not support these hypotheses. The results indicate that prevention focus had no effects on opportunism or financial performance (β = -.130, t = -1.070 and β = .090, t = .641, respectively). Overall, the evidence generally supported the hypotheses. Conclusion - Goal incongruity between a franchisor and a franchisee increases the franchisee's financial performance and opportunism, and the relationship is mediated by promotion focus. Interestingly, however, prevention focus has no mediating effect between goal incongruity and performance. Even though no significant relation exists between goal incongruity and prevention focus, the results have two implications. First, decreasing goal incongruity can improve financial performance and suppress franchisee opportunism. Second, the relationship between goal incongruity and performance affects promotion-focused franchisees.

  • 최근 우리나라는 주5일 근무제가 확대 실시되면서 여가가 많아지는 한편 각 업종별 소매점포에서의 요일별 매출도 예전과는 다른 양상을 보이고 있다. 특히 이론적으로 설명할 수 없는 요일별 수요 패턴이 체계적이고 지속적으로 나타나는 것을 요일효과라고 하는데, 요일 마케팅 관점에서 볼 때 어느 소매업종에서의 요일효과 존재여부와 그 크기를 체계적으로 파악하는 것은 소매업의 마케팅에 있어 매우 중요하다. 따라서 본 연구는 남성복 소매시장에서도 요일효과가 존재 하는지의 여부와 만일 존재 한다면 각 요일별 그 차이는 어떠한가를 알아보고자 하는 목표로 수행되었다. 그러나 요일효과 등의 이상현상에 관한 마케팅차원의 연구가 전무하여 주로 재무관리 등의 분야에서 이루어진 연구결과를 토대로 본 연구에서는 우선 개별 수요를 변화시키는 일반적 수요이론과 주식시장에서의 요일효과에 관한 선행연구 등을 토대로 이상현상에 대한 이론적 배경을 고찰 하여 소매유통시장에서의 적용가능성을 탐색하였다. 실증분석에 있어서는 국내 남성복 소매업체인 P사의 과거 5년간 매출 자료를 토대로 데이터 정제와 통계처리를 통하여 요일효과를 분석하였다. 연구결과 남성복 소매시장에 있어서도 요일효과는 존재하며, 월요일에서 일요일로 갈수록 양(+)의 요일효가를 보이고 있으며, 또한 요일효과는 계절별로 각각 다르게 나타나는 것으로 파악되었다. 본 연구는 소매업을 경영하는 기업들이 보다 효율적인 소매점포 운영방안을 강구할 수 있는데 유익한 시사점이 제공되리라 기대한다.

  • 과학적 사고가 논리적이라는 말은 무엇을 의미하는 것인가? 본 논문에서는 과학적 설명과 예측의 구조 및 가설의 검증 과정이 연역적인 구조로 되어 있음을 설명하였다. 과학적 설명과 예측의 구조를 보다 명확하게 나타내기 위해 3단 논법의 간단한 구조를 사용하였으며, 특히, 동역학이 바로 과학적 설명의 구조를 나타내고 있는 것임을 지적하였다. 이때, 많은 과학 활동이 과학적 설명보다는 예측 활동을 주로 함으로서 학생들이 동역학에 대한 이해 부족을 낳고 있다고 할 수 있다. 가설의 검증 과정을 설명하기 위해 심리학의 유명한 과제 중의 하나인 와슨의 선택과제를 가설로부터 (실험) 현상을 예측하는 과정과 (실험)관찰로부터 가설을 검증하는 두단계 과정으로 재해석하였다. 또한 가설 검증 과정에서의 대표적인 오류 중의 하나인 후건 긍정의 오류가 과학활동에서 왜 빈번하게 나타나는지를 설명하고 로슨의 다중가설 이론과 비교하였다. 연역적 사고에서 내용의 영향을 살펴보기 위해 심리학의 연구들과 과학자의 실제 활동에 대한 과학 심리학적 논의를 간단히 언급하였다. 나아가 실제 학생들의 과학 활동에서 연역적 사고가 어떠한 역학을 하는지를 알아보기 위해 실제 학생들의 과학 활동을 분석한 일련의 연구들을 조사 정리하였다.
