The aim of this study is to analysis how economic welfare lost happens within the present korea seasonal and time period electricity pricing system and find out reasonable electricity price system acceptable during the transitional period of korea electricity industry restructuring To analyze economic welfare lost in the electricity industry, in advance seasonal and time periodic 9 demand curves(summer, spring ＆fall, winter/peak-load time, middle-load time, low-load time) and one market supply curve are made and then using these demand and supply curve, seasonal and time periodic market equilibrium prices is calculated. Finally, comparing these market equilibrium prices with present regulated classified seasonal and time periodic prices, the whole economic welfare lost in the electricity industry is calculated. The result of this study shows that in 2002, the total economic welfare lost in electricity industry is 137,770 million Won and under present price system, the worst welfare lost is happening seasonally in spring ＆ fall, time periodically in the middle-load time. Specifically analyzing the characteristics of welfare lost, especially on the industry customers and service customers which are applied in seasonal and time periodic pricing, for the industry customers, the welfare lost calculated in this class occupies 51% of the total welfare lost in the whole electricity industry and the worst welfare lost is happening seasonally in spring ＆ fall, time periodically in the middle-load time. For service customers, the welfare lost calculated in this class occupies 13% of the total welfare lost in the whole electricity industry and the worst welfare lost is happening seasonally in summer, time periodically in the peak time Finally, this study was made based on the year of 2002 and KEPCO has practiced two times of rate change until now. The result of rate change was positively analyzed in the direction of economic welfare improvement(welfare improvement achieved by 16.3% compared to 2002 result).

Organizational trust is recognized as a factor that is directly linked to the organization's success in the sudden change represented by the 4th Industrial Revolution and uncertainties. This study selected trust and distrust as separate concepts and verified the structural relationship between organizational justice, psychological contract, trust, distrust, and turnover intention. Organizational justice was significant as a antecedents of distrust, whereas psychological contract was antecedents of trust, and distrust only had a significant effect on turnover intention. This result supports that trust and distrust are not one dimensions but two separate concepts. Also, organizational justice had no direct effect on turnover intention and only indirect effect through distrust was significant. This study has implications for both theoretical and practical aspects in terms of identifying the differential effects of trust and distrust.

경쟁도입을 통한 전력산업의 효율성 향상을 위해 개설된 변동비반영 발전경쟁시장이 도입되어 원자력을 포함한 6개 발전회사로 분리되어 서로 경쟁하게 되었다. 그러나 구조개편 당시 한전과의 장기전력수급계약(Power Purchase Agreement)에 따라 전력을 공급하던 민간 발전사의 경우, 기존의 계약을 시장외적인 거래로 인정하여 현재까지 일부 유지하고 있는 상황이다. 이러한 PPA는 독점적인 전력산업환경에서 민간자본을 통한 발전설비확보를 위해 개발된 제도이나 전력경쟁시장 환경하에서 PPA의 존재는 경쟁전력시장에 시장외적인 영향을 미쳐서 결국 전력시장의 효율을 저하시키는 요소로 작용하게 된다. 현재 전력시장에서 이러한 PPA를 시장 밖 요소로 처리할 경우 시장가격에 일부 영향을 줄 수 있다. 그러나 장외시장행위가 전력시장에 미치는 영향을 고려할 경우 처리방안은 여러 가지로 나눌 수 있다. 이러한 여러 가지 방법은 보다 전력시장 및 전력산업에 대한 경쟁환경 조성 및 이를 통한 효율성 확보를 목표로 하고 있다.

Die Rechtsschutzversicherung ist als eine echte Schadenversicherung eine neue Versicherung, die $Spezialit{\ddot{a}}t$ des versichertes Risikos hat. Das bedeutet, dass der Rechtschutzversicherer nur bestimmte vertraglich vereinbarte Risiken $tr{\ddot{a}}gt$. Diese Risiken sind in den Allgemeinen Bedingungen $f{\ddot{u}}r$ die Rechtsschutzversicheurng (ARB) im Zusammenhang mit Versicherungsvertragsgesetz (VVG) ${\S}$ 125 exact beschrieben. VVG ${\S}$ 125 spricht allegemein von Leistung des Versicherers im vereinbarten versicherten Umfang. Entscheidend ist also die Vereinbarung in den ARB, welche in ${\S}$ 1 die Kostentragung $f{\ddot{u}}r$ den Versicherten als Hauptleistung des Versicherers beschrieben ist. Also in den VVG ${\S}{\S}$ 125 bis 129 gibt es keine Definition ${\ddot{u}}ber$ die Sparte der Rechtsschutzversicherung, jedoch mindestens es $w{\ddot{a}}re$ $m{\ddot{o}}glich$, diese Sparte zu definieren. Um die $k{\ddot{u}}nftige$ Produktentwicklung nicht zu hindern, $enth{\ddot{a}}lt$ die Vorschrift keine gesetzliche Definition der Rechtsschutzversicherung nach Angabe der amtlichen $Begr{\ddot{u}}ndung$. Weil in Korea die Rechtsschutzversicherung relativ neu in Versicherungsmarket ist, sind daher VVG ${\S}{\S}$ 125 ein gutes gesetzgeberisches Vorbild, um pragmatisch und auch dazu rechtswissenschaftlich zu diskutieren und diese fsetzustellen. Im Schritt von Ausdehnungen der juristischen Dienstleistung $w{\ddot{a}}re$ es $n{\ddot{o}}tig$, zu betrachten, wie Leistungsumfang des Versicherers in der Rechtsschutzversicherung erweitert werden kann. And noch dazu ist die Informationspflicht des Versicherers in Hinsicht auf Versicherungsunfall und Leistungsumfang noch weitert zu ${\ddot{u}}berlegen$, weil diese Sparte der Rechtsschutzversicherung noch professioneller als die anderen Versicherungsbereiche ist.

In this study, transaction cost approach was applied to analysis on direct export determinants of SMEs by using key attributes of transactions, asset specificity, environmental uncertainty, frequency and marketing capability, with a parameter of opportunism. Typical Transaction Cost Analysis theory explains that when transaction cost with business channels(whether it is for buy or sell) increase, the firms integrate the channels. So it is a choice made by firms regarding direct versus indirect channels. The theory was extended to a model of choice of institutional form of direct or indirect export by a norm of opportunism in this empirical study. The survey result showed that lower level of asset specificity and marketing capability or higher level of environmental uncertainty were likely to expose indirect exporters to higher level of opportunism of direct exporter. And we also saw that indirect exporters were likely to choose direct export chanel when opportunism of exporters was higher. From the standpoint of theory, we can say that the basic propositions of the Transaction Cost Analysis, except the attribute of frequency, are supported. This study result could provide a profiling of target business areas and firms for government's policy on direct export promotion of SMEs.

Due to the great advances in e-Marketplace and changes in type of items purchased from the online market, it has been dramatically increased the demand of the storage and transportation under the special conditions such as restricted temperature. Especially, the cold chain needs the way to transparently measure and monitor the entire network in realtime because it has a very complicated structure and requires totally different criteria at the every different steps and items. In this research, it has been presented the performance evaluation metrics to make contract using service level agreement (SLA), the way to apply the smart contract based on blockchain, the structure of blocks, service platform and application in order to build cold chain which can prevent the risk factors by measuring and sharing information in realtime using block chain technology. In addition, we have proposed the way to store the measured performance and reputation of each player in the block using smart contract based on SLA. With the presented framework, all players including service providers as well as users can secure the information for making the rational decisions. When the service platform is actually built and operated, it seems possible to secure the information in transparently and realtime. Also, it is possible to prevent the risk factors or prepare the preemptive plans to react on them.

"급수장치"라 함은 수도사업자가 일반의 수요자에게 정수를 공급하기 위하여 설치한 배수관으로부터 분기하여 설치된 급수관, 계량기, 저수조, 수도전, 기타 급수에 관련된 기구를 말한다. 우리나라에서는 수도시설의 급수장치의 구조 및 재질에 대해 따로 정한 사항이 없고 수도법 시행령 제18조의2에서 정한바와 같이 일반적인 수도용 자재기준에 따르도록 규정하고 있다. 한편 일본의 경우를 살펴보면 급수장치가 갖추어야 될 구조 및 재질에 관한 사항을 수도법 시행령으로 규정하고 있고 수격한계, 유해물질의 침출성능 및 역류방지 등에 관한 품질특성치를 후생성령으로 정해 수도사업자의 급수의무에 대응하여 공급계약시 수용가의 준수사항을 상세히 규정하고 있다. 우리나라에서도 급수장치가 일반적인 수도용 자재와 구분되어 관리될 필요가 있다고 판단하고 우선 일본의 급수장치의 구조 및 재질에 관한 후생성령을 번안하여 수록하였다.

한국 IT아웃소싱서비스 산업이 안고있는 문제의 근원은 아웃소싱서비스 산업구조에서 그 원인을 찾을 수 있다. 이러한 산업구조의 문제가 서비스의 질적인 문제, 방법론의 정교화 문제, 계약의 문제 나아가서는 한국 소프트웨어 산업의 경쟁력 약화에 관한 모든 문제를 잉태하고 있다. 한국 IT아웃소싱 산업구조의 특이성을 무시한 IT아웃소싱의 문제나 문제의 증후군을 대상으로 한 연구나 정책적 해결책을 제시하는 것은 대증적 치료방법에 불과하며 한국 아웃소싱 산업의 경쟁력 확보 전략에 미미한 공헌을 할뿐이다. 우리가 미국이나 여타 국가의 아웃소싱 사례를 한국의 상황에 투영하여 이를 치유의 방안으로 제시하는 어리석음을 벗어나야 하는 이유가 여기에 있는 것이다. 본 논문의 목적은 이와 같은 한국 정보기술 아웃소싱 산업의 근원적 문제구조를 제시하고 이것이 의미하는 IT아웃소싱 연구 방향을 제시하는 데 있다.
