본 논문에서는 순간전압조정, 역률 보상, 고조파 저감에 대한 배전용 정지형 동기조상기(STATCOM : STATic COMpensator)에 대한 다양한 제어 모드를 제안하고 있다. 이러한 제어 알고리즘의 성능을 검증하기 위해 각 제어 알고리즘을 20kVA의 축소형 STATCOM에 적용하고 간단한 배전계통을 꾸며 시험하였다. 실험결과로부터 제안한 제어알고리즘이 Custom Power 시스템으로 훌륭한 성능을 보임을 확인할 수 있었다. 실재 배전계통에 적용하여 현재 1MVA STATCOM이 성공적으로 운전되고 있다.

This study examines the negative relationship between accounting conservatism and excess executive compensation and examines whether their relationship increases as managerial incentive compensation intensity increases. For this purpose, a total of 2,755 company-years were selected for the analysis of the companies listed on the Korea Stock Exchange from December 2012 to 2016 as the final sample. The results of this study are as follows. First, there is a statistically significant negative relationship between accounting conservatism and manager overpayment. This implies that managers' incentives to distort future cash flow estimates by over booking assets or accounting profits in order to maximize their compensation when manager compensation is linked to firm performance. In this sense, accounting conservatism can reduce opportunistic behavior by restricting managerial accounting choices, which can be interpreted as a reduction in overpayment to managers. Second, we found that the relationship between accounting conservatism and excess executive compensation increases with the incentive compensation for accounting performance. The higher the managerial incentive compensation intensity of accounting performance is, the more likely it is that the manager has the incentive to make earnings adjustments. Therefore, the high level of incentive compensation for accounting performance means that the ex post settling up problem due to over-compensation can become serious. In this case, the higher the managerial incentive compensation intensity for accounting performance, the greater the role and utility of conservatism in manager compensation contracts. This study is based on the fact that it presents empirical evidence on the usefulness of accounting conservatism in managerial compensation contracts theoretically presented by Watts (2003) and the additional basis that conservatism can be used as a useful tool for investment decision.

The 「Act on Remedies for Injuries from Medical Malpractice and Mediation of Medical Disputes」(hereinafter referred to as 'the Act on Mediation of Medical Disputes') provides that the state should compensate the victims of medical accidents occurred irresistibly in childbirth despite that health and medical service personnel fulfilled their duty of care for their damage within the range of its budget(Article 46 of the Act on Mediation of Medical Disputes). Given that victims of medical accidents could expect demage recovery only through lawsuits thus far, this act can be said to be a groundbreaking act. However, However, as 30% of the costs for such medical accident compensation projects are borne by those who have records of childbirth among the founders of health and medical institutions (Article 21 of the Act on Mediation of Medical Disputes), there has been a question about whether doctors are held responsible despite that the accidents such as the deaths of mothers and newborn babies occurred irresistibly without doctors' fault. However, recently, the Constitutional Court ruled that 'the range of founders of health and medical institutions' and 'share ratios of finances for compensation' in Article 46 (3) of the Act on Mediation of Medical Disputes' related to the imposition of the share of costs are institutional (Constitutional Court ruling dated April 26, 2018, 2015Heonga13, hereinafter referred to as 'the ruling in the case'). Although the ruling in the case was made based on only the principle of statutory reservation and the principle of ban on comprehensive authorization, this paper added a practical judgment. This paper proved that the share of costs in this case has the nature of burden charges in pursuit of study and does not infringe on the property rights of the founders of health medical institutions even in light of the principle of proportionality because there is a legitimate reason for imposing the burden charge. The imposition of the share of costs in the system for compensation for medical accidents occurred irresistibly is against the principle of liability with fault in part. However, the medical accident compensation projects are rational a national policy for the victims of medical accidents and the medical world clearly gains some benefits from the effect to terminate medical disputes. The expansion of finances for compensation through the payments of the share of costs will reduce the suffering and misunderstanding of victims of medical accidents occurred in the process of childbirth and will be very helpful to the construction of stable treatment environments of medical workers by quickly establishing the medical accident compensation projects as such.

A rotor flux error-based approach for correcting the rotor time constant estimation used in the slip frequency calculator of indirect field oriented controller is presented in this paper. The controller was derived from the d-q induction machine model. Slip frequency gain is dependent on the machine parameter errors. And parameter errors result in rotor flux error. Thus, estimated rotor flux is compared to commanded rotor flux. The error between them is used for the estimation of rotor time constant. Simulation results which demonstrate the performance of this approach are presented.

최근 국방예산의 공개와 투명성 확보를 요구하는 사회적 관심이 고조되어 투자 우선순위 조정 및 합리적인 제도 운영을 통한 예산의 효율적 집행이 중요시되고 있다. 쌍방독점의 형태를 가지는 방산물자의 조달에 있어서는 단순히 국가예산의 절약 뿐만 아니라 국방 목적을 위하여 품질과 성능 등 제품의 신뢰성에도 중점을 두어야 한다. 그러나 예산의 절약과 제품 신뢰성의 확보는 서로 상충되는 특성을 가지고 있다. 그러므로 방산물자와 관련된 원가계산 및 이윤산정에 관한 규정은 이러한 상충되는 목표를 적정하게 달성할 수 있도록 기업과 정부양측에게 공정한 가격의 설정을 지향하여야 한다.

대리운전업체에 소속되어 있는 대리운전자가 대리운전 보험에 가입한 경우, 보험료는 대리운전자가 직접 부담하는 경우가 대부분이나 계약당사자인 보험계약자는 대부분 대리운전업체로 되어 있다 보니 약관내용에 대해 제대로 설명을 듣지 못했다는 이유로 보상범위 등을 둘러싼 분쟁이 발생하는 경우가 많다. 본고에서는 차주가 동승하지 않은 채 대리운전자가 차량을 운전하던 중 발생한 사고를 대리운전보험에서 담보하는 '대리운전 중 사고'로 볼 수 있는지 여부를 다룬 사건을 소개하고자 하는데, 쟁점 가운데 약관의 설명의무와 관련 사항을 일부 언급하고 있어 동 내용을 살펴보고 나아가 약관 설명의무의 법적 성격 및 유사 분쟁사례 등을 개관하고자 한다.

In this paper, a novel IQ modulator that precisely controls the magnitude and phase of input signals is proposed. The proposed IQ modulator consists of low phase deviation attenuators, a splitter, and a combiner. In order to overcome the phase deviation characteristics found in conventional attenuators, a novel phase compensation technique has been adopted and mathematically analyzed. Linear vector arrays along the center point with large magnitude output signal variations in a full $360^{\circ}$ phase control are achieved on a polar plane by the proposed IQ modulator.

In the construction industry, projects are becoming increasingly large and complex, involving multiple subcontractors. Traditional centralized coordination techniques used by the general contractors become less effective as subcontractors perform most work and provide their own resources. When subcontractors cannot provide enough resources, they hinder their own performance as well as that of other subcontractors and ultimately the entire project. Thus, construction projects need a new distributed coordination approach wherein all of the concerned subcontractors can reschedule a project dynamically. To enable the new distributed coordination of project schedule changes, I developed a novel agent-based compensatory negotiation methodology, which allows software agents to simulate negotiations on behalf of their human subcontractors. This research formalizes the necessary steps that would help construction project participants to increase the efficiency of their resource use, which in turn will enhance successful completions of whole projects.
