The objective of this study is to examine the relationship between the degree of business diversification of a construction company and two of the indicators that represent financial stability, namely, a current ratio and a debt ratio, in order to draw policy implications. The current ratio and the debt ratio were used as variables that represent financial stability of a construction company. Berry-Herfindahl Index was used to measure the degree of business portfolio diversification of a construction company. For the analysis, quarterly time series data were retrieved from the financial information disclosure system of Korea's Financial Supervisory Service for the period between the first quarter of 2001 and the third quarter of 2013. The analysis results showed that a higher current ratio and a debt ratio led to a greater extent of business diversification. A higher level of business diversification led to a higher current ratio and a lower debt ratio. It was also shown that the impact of business diversification on the current ratio and the debt ratio outweighed the impact of changes in the current ratio and the debt ratio on business diversification. Meanwhile, an increase in the level of business diversification showed a quite positive effect as it raised the current ratio and lowered the debt ratio of a construction company. These findings suggest that diversification of business portfolio is essential for construction companies to strengthen their financial stability.

In the case of SMEs, entrepreneurship that organizes only core functions with the minimum number of people is increasing, and a responsibility management system focusing on core functions is emphasized, so that the interest in innovation behavior and survival strategy of enterprises is getting bigger. However, in the case of SMEs, it is not easy to pursue continuous innovation due to lack of capital and lack of professional manpower. The purpose of this study is to investigate the effect of SME on innovation behavior by selecting exploratory study and literature study for SMEs. The data for this study were 545 out of the total 600 copies distributed to employees in SMEs. The data were analyzed using SPSS 21.0 and amos18.0. First, product diversification, strategy formulation, and R & D have a significant effect on innovation behavior, and market diversification has no effect on innovation behavior. Second, working variables such as product diversification, market diversification, strategy formulation, and R & D do not control the influence of innovative behavior on innovation behavior. Third, the rank variable, which is the controlling variable, controls the magnitude of the effect of product diversification, market diversification, strategy formulation, and R & D on innovation behavior. As a result, corporate managers should lead the organization in order to promote product diversification, market diversification strategy, R & D and innovation activities. After discussing the conclusions and implications of this study, this study presented the direction of the research for the follow-up study.

In this study, how international diversification of domestic companies increases corporate profits and increases the dividend income of paid-in capital investors, who provided the basis for corporate business activities in the process of distributing profits. I tried to find out if it had an effect. An empirical analysis was conducted using a fixed-effect model for companies with settlements at the end of December listed on the domestic securities market from 2011 to 2018. It was confirmed that the higher the level of international diversification of individual companies, the higher the company's dividend payout ratio and dividend yield. This means that companies can steadily expand corporate profits and dividend yield of shareholders by securing new overseas markets through international diversification, it can be seen that a company's international diversification strategy can contribute to the increase of corporate value by increasing the company's dividend payout ratio by increasing dividendable profit.

본 논문에서 우리는 최적화 문제를 효율적으로 해결하기 위한 새로운 유전 알고리즘을 제안하였다. 새로운 유전 알고리즘의 가장 큰 특징은 서로 다른 목적을 가진 2개의 집단을 가지고 진화를 수행한다는 점이다. 하나의 집단은 일반적인 유전 알고리즘의 그것과 비슷하지만, 좋은 영역의 탐색에 집중하는 경향을 보이며 다른 하나의 집단은 이러한 좋은 영역에의 집중 시 나타날 수 있는 조기 수렴 문제를 보완하기 위해 탐색을 다각화 하는 방향으로 진화한다. 몇 가지 최적화 문제에 대한 실험 결과 이러한 특성이 다른 2개 집단에 의한 진화 방법이 문제 해결에 도움이 됨을 확인할 수 있었다.

본 연구에서는 우리나라 234개 상장기업을 대상으로 기업의 소유구조와 자본구조의 상호관계가 기업다각화에 미치는 영향을 2단계 최소자승법(2SLS)을 이용하여 분석하였다. 우리나라 기업의 소유구조와 자본구조의 상호관계를 분석한 결과를 요약하면 첫째, 1996년부터 1999년까지의 전기간 분석에서 우리나라 기업은 소유구조와 자본구조 정책을 서로 연계하여 결정하는 것으로 나타났다. 그러나 IMF 경제위기 전후기간으로 구분하여 상호영향관계를 분석한 결과에 의하면 IMF 이전기간에는 소유구조와 자본구조가 상호의존적인 영향관계가 있는 것으로 나타났지만, IMF 이후기간에는 소유구조와 자본구조의 상호영향관계를 발견할 수 없었다. 둘째, 내부자는 부채사용에 따른 재무위험의 부담을 줄이기 위해 레버리지 비율이 높으면 내부지분율을 감소시키는 것으로 나타났다. 넷째, 내부지분율이 높으면 내부자는 자신이 부담해야 하는 재무위험을 줄이기 위해 레버리지 비율을 낮추는 것으로 분석되었다. 한편, 소유구조와 자본구조의 상호관계가 기업다각화에 미치는 영향을 분석한 결과에 의하면, 소유구조와 자본구조의 상호관계가 기업다각화 수준에 영향을 미치지 않는 것으로 나타났다.

Since diversification can be a necessary means for company's survival and the conservation of its success, hundreds of studies have been done by three schools of industrial economics, strategic management, and Neo-Schumpeterian economics for over 30 years. However, any school has not presented a model comprehensively explaining diversification' success or failure. The study tried to suggest a theoretical framework integrating findings came from three schools. The framework considers both firm's technological capabilities and sector-specific characteristics as well as reflects a Neo-Schumpeterian view emphasizing technological aspects. The goal of the study is finding major reasons of success and failure during company's diversification through studying three diversification cases of Samsung. Our findings show that the diversification toward TFT-LCD was easier and more successful than the diversification toward microprocessor because DRAM is more similar to TFT-LCD than microprocessor. Samsung also tended to build only the types of capabilities which were originated from capabilities accumulated in DRAM business. Our findings give firm's strategists a lesson that they can increase the probability of success in diversification, if only they should simultaneously consider a new sector's characteristics, a firm's technological capabilities accumulated in old sectors, and the availability of old capabilities for being applied to a new sector.

This questionnaire study examined the processes linking complexity of self-construal to self-positivity conceptualized as taking multiple perspectives, self-acceptance and self-regulation that, in turn, affect psychological well-being among people with an experience of life-crisis during adulthood due to physical disability or divorce. Data were drawn from 359 adult Koreans residing in Seoul metropolitan area, including the physically disabled, the divorced, and their counterparts without a life-crisis experience during adulthood for comparison. On average, the life-crisis experience group(LEG) had a higher independent selfconstrual and a lower interdependent self-construal than the comparison group(CG). As predicted, complexity of self-construal contributed to taking multiple perspectives that helps searching for meaning, and this, in turn, was found to foster self-acceptance and self-regulation. Through these variables except self-regulation, complex self-construal contributed to psychological well-being as manifested by a higher level of positive emotion and a lower level of depression. As expected, while taking multiple perspectives fostered positive emotion both directly and indirectly through self-acceptance among LEG and CG, only in LEG it directly reduced depression. The comparative approach employed in this study enabled to discern that taking multiple perspectives promotes psychological well-being in LEG by contributing to both meaning making and positive attitude, whereas it promotes psychological well-being in CG primarily by fostering positive attitude. Finally implications for this study were discussed and directions for future research were suggested.
