The purpose of this study are to provide the basic data materials and implementations for successful performance of electric-work field representatives of South Korean firms by identifying their roles and competency and examining their educational need. For this research purposes, three phased analysis was followed on: (1) the roles of electric-work field representatives, (2) competency of electric-work field representatives and (3) educational need for their competency. This research method was to conduct a focus group interview for 10 expert field representatives along with survey. The collected data materials were processed by MS Excel and SPSS 21.0 for statistical analysis including average, standard deviation and other basic statistics; the gap in awareness of field representatives; and need values. For the needs analysis, the difference between significance of field representatives' competency and current status was examined by t test. And the awareness gap between competency importance and current status was identified based on the Borich equation. The Locus for Focus model was employed herein to identify the kinds of competency with high importance and high inconsistency to prioritize. As a result, this research has found as follows: first, the roles of field representatives were found to be in 13 different kinds of roles. Second, electric-work field representatives were found to need to have 16 different skills. Third, regarding the 16 abilities, the gap between current status and significance was analyzed herein. The results showed statistically significant differences in all cases. The Borich needs analysis found the first required ability was communication ability followed by power of execution, conflict management ability, analytical thinking and time management ability. Also, the results of Locus for Focus model analysis displayed that the first quadrant(HH) included 7 highly-demanded abilities of communication ability, analytical thinking, decision making ability, specialty, time management ability, power of execution and drive for work implementation. The top-priority group was found to have 5 items of communication ability, analytical thinking, time management ability, power of execution and drive for work implementation which were commonly seen in the Locus for Focus model outcomes. Based on these findings, this research could identify the roles and competency of electric-work field representatives and provide the basic data materials applicable to future personal management of electricity companies including recruitment, division of work, job description, evaluation, etc. Also this research offered guidelines on demanded abilities in the field and where to place priority. The kinds of abilities with high educational demand as found in this research must be considered in designing educational programs for the competency building of field representatives. This research is expected to provide useful information in developing such educational programs for field representatives.

본 논문은 다기간 대리모형에서 나타날 수 있는 대리비용 중에서 대리인과 위임자의 의사 결정고려기간(decision-making horizon)의 차이로 인해서 발생할 수 있는 과소투자유인을 연구 대상으로 하고 있다. 대리인인 경영자는 자신의 명성을 고려해서 투자효과가 자신의 임기내에 나타나는 투자안에 높은 관심을 가질 것이다. 그런데 계속기업을 전제로 하면 대리인인 경영자는 위임자인 주주보다 투자의사결정시 고려하는 기간이 짧아서 과소투자의 가능성이 존재한다. 동적최적화 기법을 이용한 이론적 모형의 결과도 대리계약기간이 짧을수록 투자수준이 낮을 것으로 나타났다. 이러한 내용을 한국상장기업들을 대상으로 임원근속기간과 설비투자수준의 관계에 대해서 실증분석한 결과, 이론적 기대와 일치하지만 통계적 유의성은 낮은 편이었다. 이같은 결과는 전문경영체제가 확립되어 있지 않은 한국기업환경의 특성에 기인한다고 생각된다.

Blockchain technology prevents tampering of central authorities that manage voting process, enhancing trust in the vote results. This technology enables citizens to participate more directly in the areas where delegation was inevitable due to the difficulties in polling fair and trustworthy public opinions. There are many projects around the world proposing to implement voting system for public decision making using blockchain technology. The blockchain voting system is expected to work as a transparent and fair channel for polling public opinions, which will transform the public decision-making process and governance. Korean National Pension Service (NPS) recently introduced stewardship code to better represent the interest of beneficiaries. However, because of the mistrust in governance of NPS, introduction of stewardship code is facing criticism for potential misuse of their voting rights against the interest of beneficiaries and for government's interference with corporate management. This study proposes a voting system applying blockchain technology for polling the opinions of National Pension Fund's beneficiaries to support public decision-making, and discusses social and institutional conditions for implementation of the proposed system.

Recently, Practicing of ghost surgery and duty of informed consent of doctors have become a big issue in the medical dispute and lawsuits. The ground of admitting the informed consent and the agreement(self-determination of patients) can be based on the dignity of man and the right to pursue his happiness guaranteed under Article 10 of the constitution in theory. However there are no explicit legal regulations on the duty of the informed consent and there is no substantive legal enactment on the informed consent, but there is a collision between self-determination of patients and the discretionary power of doctors. If the discretionary power on the duty of the informed consent was extended it may result in the infringement of the right of surgical patients, so called arbitrary medical treatment. Relating to this issue, New Jersey Supreme Court held that a patient has the right to determine not only whether surgery is to be performed on him, but also who shall perform it. Moreover it held that a surgeon who operates without the patient's consent engages in the unauthorized touching of another and, thus, commits a battery'. But there are no ghost surgery cases adopting battery theory in Korea, and professional negligence has been considered rather than the battery, regarding an absence of hostile intent to injure patient. Supreme Court of Korea held that a doctor who operates a medical procedure without the patient's valid prior consent based on wrong diagnosis commits professional negligence resulting in injury, and the patient's invalid consent do not preclude wrongfulness'. However, if a health care provider conducts a completely non-consensual treatment or substitute surgeon without consent, the action should be plead in battery, not negligence, but if a health care provider violate his duty of care in obtaining the consent of the patient by failing to disclosure all relevant information (risks) that a reasonable person would deem significant in making a decision to have the procedure, the action should be plead in negligence, not battery. Therefore, the scope of patients' self-determination can be protected by stating clearly the scope of the duty of the informed consent and the exemption of the informed consent legislatively, it is considered that it is valid to legislate the limitation of the discretionary power.

This study suggests a method of command and control in modeling a combat situation. In particular, it presents the structure of an intelligent agent that may substitute for the current system of decision making in the military operation to lead a troop. Today the Korean military war game simulations emphasize on engagements, instead of command and control. This suggested principle will be a good foundation for the today and the future Korean warfare.

With respect to the cause of asymmetric cost behavior, there are two streams of the literature. One stream focused on effect of managerial expectation and the other explained using agency system. In this study, we aim to investigate the determinants of asymmetric cost behavior in these streams. We first examine the impact of managerial overconfidence and optimistic bias on asymmetric cost. We also examine ownership ratio as a proxy of the quality of corporate governance effects on asymmetric cost. The results are as follows. First, firms have the anti-sticky asymmetric cost behavior. Second, we find that the firms with managerial optimistic bias mitigate the degree of asymmetric cost. This finding implies that managerial optimism is a factor that alters asymmetric cost behavior. Third, the degree of asymmetric cost is weaker in case of firms with higher manager's ownership. This result provides an important empirical evidence for understanding the role of corporate governance in cost behavior.

본 논문은 미국 다국적 기업의 해외 합작투자 발표가 개별 기업의 주식 가격에 미치는 영향에 관하여 분석하였다. 본 연구에서는 개별 기업의 경영능력 및 대리인 비용의 존재 여부에 따라 기업의 투자의사 결정시 증권시장이 차별적으로 반응한다는 점을 가설화하였으며 이를 실증연구를 통하여 입증하였다. 평균적으로 해외 합작투자 발표 당일에 주가 상승으로 인한 평균초과수익율은 0.4%로 기업 인수 합병에서 인수 기업이 실현하는 수익률에 상응하는 수준이었다. 본 논문의 실증연구 결과는 Jensen(1986)이 제시한 '사내잉여자금-과잉투자'(Free Cash Flow - Overinvestment)가설과 대체로 일치하고 있다. 즉, 기업의 관리능력이 뛰어나고 사내에 축적된 잉여자금의 양이 적은 경우 해외 합작투자 결정은 증권시장의 호의적인 반응을 받은 반면 경영이 부진하고 사내에 유보된 잉여자금의 양이 많은 기업의 경우 투자자의 관심을 끌지 못하였음을 알 수 있다.
