김범건(Kim Beom-Geon),권오진(Kwon Oh-Jin),최순재(Choi Soon-Jae) 한국국제회계학회 2017 국제회계연구 Vol.0 No.75

본 연구는 기업의 사업다각화수준과 가결산 정보의 정확성 간의 관계를 분석하고, 기업의 소유구조에 따라 이러한 관계가 어떻게 달라지는지를 살펴보고자 한다. 경영자가 사업다각화를 이용하여 사적효익을 추구한다면 다각화가 심화될수록 경영자는 기회주의적인 행동을 감추려할 것이다. 이로 인해 경영자와 이해관계자 간의 정보비대칭이 커지고, 기업의 공시품질 역시 낮아질 것으로 예상된다. 한편으로는, 사업다각화 기업의 경영자가 이해관계자들의 요구를 반영하여 정보비대칭을 해소하고 대리인 문제를 완화하기 위해 공시품질을 높이려는 유인도 존재할 수 있다. 이처럼 사업다각화 수준과 공시품질 간 양방향의 예측이 가능하지만 일관된 실증결과가 존재하지 않기 때문에, 본 연구는 공시품질의 대용치로 가결산 정보를 사용하여 기업의 사업다각화수준과 공시품질 간의 관계에 대한 실증분석을 수행한다. 나아가 우리나라는 기업 운영에 실질적 소유주의 의견이 많이 반영되기 때문에, 사업다각화 수준과 공시품질 간의 관계에 최대주주 및 외국인주주가 어떠한 영향을 미치는지를 분석한다. 실증분석결과, 기업의 사업다각화 수준이 높을수록 가결산 정보의 정확성은 높아지는 것으로 나타났다. 이는 사업다각화 수준이 높아질수록 경영자가 이해관계자들을 고려하여 정보비대칭을 완화시키기 위하여 공시품질을 높이는 것으로 해석할 수 있다. 다음으로 사업다각화 수준이 높은 기업에서 최대주주 지분율이 높다면, 가결산 정보의 정확성은 낮아지는 것으로 나타났다. 이는 사업다각화 수준이 높을수록 최대주주는 부정확한 공시를 통해 사적 효익을 추구할 가능성이 존재한다는 것을 의미한다. 마지막으로 사업다각화 수준이 높은 기업에서 외국인주주의 지분율이 높더라도 가결산 정보의 정확성은 낮아지는 것으로 나타났다. 이러한 결과는 외국인주주는 내부정보에 대한 접근권이 낮기 때문에 사업다각화로 인해 기업이 복잡해질수록 감시역할을 제대로 수행하지 못한다고 볼 수 있다. This paper investigates the association between the level of business diversification and the accuracy of preliminary earnings, and examine how there is any difference according to the ownership structure. The disclosure is important to alleviate information asymmetry among information users of diversified firms. In the perspective of agency problem, it is possible that managers of the diversified firms improve disclosure quality to alleviate information asymmetry, contrary they may reduce disclosure quality to have private benefit. So, we analyze the relation between the level of diversification and disclosure quality(proxied by preliminary earnings). In addition, corporations could be operated by the opinions of de facto owner in Korea. So, we analyze the effect of the largest shareholders on the relationship between diversification level and disclosure quality, and analyze whether foreign investors monitor management. For our analysis, we use firms listed on KSE from 2002 to 2014 period. The result are as follows. First, the relation between the level of business diversification and the difference of preliminary earnings and actual earnings is negative. This result implies that managers enhance disclosure quality to alleviate information asymmetry when the level of diversification is higher. Second, the accuracy of preliminary earnings are low when the shares owned by largest shareholder are higher in the firms of high diversification level. This means that the higher the level of diversification, then the largest shareholders reduce disclosure quality and they pursue private benefit. Third, despite the higher shares owned by foreign, the firm on higher level of diversification decreases disclosure quality. This result suggests that it is difficult for foreign shareholders to access internal information when the firm becomes more complicated by diversification, so they can’t monitor insiders.

This paper presents results of dynamic analysis for a bridge in intersection part of two tunnels subjected to moving vehicle loadings. Since such a bridge system is very unusual due to the fact that it is located in tunnel, the dynamic characteristics of the structure can not be assumed as conventional one. The structure investigated in this study is a reinforced concrete bridge in the intersection part of Namsan Tunnel-1 and Tunnel-2 in Seoul. It is supported by temporary steel structure which shall be constructed during the period of replacing lining in Tunnel-2. Dynamic analysis was carried out for the system using a finite element model constructed by general purpose FE program SAP2000. For this purpose, the structure, lining of tunnels, and surrounding rock were represented bey finite elements, while the rock region is truncated and on its outer boundary viscous dampers were placed to simulate radiation of elastic waves generated in tunnels. Several types of vehicles with various driving velocities were considered in this analysis. The FE model including vehicle loadings was verified by comparing calculated peak particle velocity with the measured one. From the analysis, the impact factor for the bridge was estimated as 0.20. Therefore it has been concluded that the use of upper bound for the impact factor specified in design code is expected to be conservative for this kind of bridge system.

정재천,박기원,노건상,오후규 여수대학교 1998 論文集 Vol.12 No.2

A basic heat pump system was designed and manufactured, in which a pair of bare tube was constructed as main heat exchanger. New natural refrigerants R-290 and HCFC refrigerant R-22 were used. In this paper, cycle characteristics of global heat pump, evaporation and condensation heat transfer characteristics were studied and a basic data base for the optimum design of refrigeration and air-conditioning systems was obtained. On the condensing and evaporating heat transfer characteristics, the average heat transfer coefficient was obtained the higher value in R-290 than R-22 refrigerant. Characteristics of heat pump cycle were researched based on the compressor shaft power, cooling capacity and coefficient of performance. From these results, the heat pump cycle characteristics were more affected from the refrigerant properties and operating conditions. Considering the results, R-290 refrigerant has a sufficient ability to substitute R-22 due to its higher performance.

SnO_(2) doped with TiO_(2) and other activating agents, is used as a raw material to prepare humidity sensors. SnO_(2) is an n-type semiconductor whose resistance is described as a function of relative humidity. SnO_(2)/TiO_(2) thick film humidity sensors have been fabricated by using typical silk screen printing techniques. The humidity sensitivity of SnO_(2)/TiO_(2) thick film has been investigated. And the sensing characteristics of the fabricated SnO_(2)/TiO_(2) sensors such as resistance change and response time, has been investigated from R.H.20 % to 90 %. Experimental results show that the impedance-humidity characteristics of the humidity sensors depend on the microstructure of surface roughness and pore size distribution.

Since the technology is one of the important factor for the development of countries or companies, evaluation of technology became essential for investment on venture company, technology trading and M&A. The appropriate evaluation of technology is so important yardstick of competence of business that, in this thesis, the theories and the present conditions of technology evaluation model in several institutes are compared and analysed and also the desirable direction for the future right model are suggested. Technology evaluation model is basically composed of three parts: cost-market-income approach method, technology factor method, real option method. We have to choose proper model among several methods because there are various technology evaluation methods and they have different merits and demerits. So that, due to some limits for each model, there is no complete one which can drive the right valuation by itself at one time. Thus, right valuation seems to be required that several different methods of each model should be applied and analysed at the same time and then decide the right answer that satisfies the suggested conditions.

Leadership의 認識論的 考察

金在健 상명대학교 논문집 1984 상명대학교논문집 Vol.13 No.-

Ⅰ. Approaches This study aimed at approaching the epistemological consideration of leadership. Up to now, as most studies on leadership has been carried out on the behavioral science method, it was unable to understand the leadership of a man on the whole. Therefore, the three leading theories of leadership, the trait theory, the situational theory and the interrelationship theory, have failed to see and examine the whole concept of leadership as they tried to define leadership from the partial, mechanical and consequential viewpoints. These behavioral science theories have examined and analyzed the leadership of man too extremely scientifically and subdivisionally. As a result, these theories of leadership were unable to see and define leadership on the whole. In order to conquer these limitation, the researcher attempted to define leadership with the total concepts through micro and macroscopic approaches. By doing so, the researcher tried to study leadership through the espistemological approach in order to define leadership on the whole view points. Ⅱ. Conclusions In view of this, this researcher presents the following as the conclusions of this study: 1. In order to conquer the limitation of the theories of leadership based on the behavioralism, it is desirable to understand leadership through the espistemological approach. 2. It is also desirable that "knowledge" is required as the efficient and available concepts when leadership is approached through the espistemological consideration.
