With the rapid development of block chain technology, attempts have been made to put the block chain technology into practical use in various fields such as finance and logistics, and also in the public sector where data integrity is very important. Defense Operations In addition, strengthening security and ensuring complete integrity of the command communication network is crucial for operational operation under the network-centered operational environment (NCOE). For this purpose, it is necessary to construct a command communication network applying the block chain network. However, the block chain technology up to now can not solve the security issues such as the 51% attack. In particular, the Practical Byzantine fault tolerance (PBFT) algorithm which is now widely used in blockchain, does not have a penalty factor for nodes that behave maliciously, and there is a problem of failure to make a consensus even if malicious nodes are more than 33% of all nodes. In this paper, we propose a Adaptive Consensus Bound PBFT (ACB-PBFT) algorithm that incorporates a penalty mechanism for anomalous behavior by combining the Trust model to improve the security of the PBFT, which is the main agreement algorithm of the blockchain.

The total number of Sea Area Utilization Consultation in the environment management sea areas reviewed from 2015 to 2017 were 60. The number of development projects in the environment conservation sea areas decreased steadily, but special management sea areas increased. Development types in environment management sea areas showed that artificial structure installation was the highest ratio, followed by fishery port development and construction of habor and coastal maintenance and sea water intake and draining. By comparing the trend of water quality changes using marine environment information system (MEIS) data in the environment management areas from 2006 to 2017, COD showed no significant changes but the environment conservation sea areas increased slightly, and the concentration of TN and TP decreased. Gwangyang and Masan bays in the special management sea areas and Gamak bay in the environment conservation sea areas displayed oxygen deficient mass in the summer. As the use of development projects of the environment management sea areas are performed continuously, an analysis of the status of sufficient water quality changes is necessary for environmental impact assessment (Sea Area Utilization Consultation) in the marine environment and should be evaluated mainly for management of contamination by diagnosing thoroughly water quality effects and the pollution of sediment. Especially, the water quality goal for the purpose of designation in each of the environment management sea areas is set clearly, connection with pollution source control and the total pollution load management system (TPLMS) should be proposed and measured to reduce the amount of contaminated water.

This research focuses on the perceived marketplace influence(PMI: A belief that recognizes the effect that an individual's actions will have on the behavior of other consumers in the market and thus drives them to act on fair trade consumption) of consumers who may act as a more fundamental explanatory alternative to the gap in attitudes and behaviors of fair trade products. The purpose of this study is to investigate the relationship between consumer's self - determination psychological needs (autonomy, competence, relevance), influence (personal influence, market influence), and the assets of fair trade products. As a result of the empirical analysis, it was found that among the major psychological needs related to self-determination, the variables other than competence and the perceived influence relations of consumers can be directly formed, and the perceived consumer effectiveness(PCE) has a positive influence on perceived marketplace influence(PMI). It is also found that the perceived influence of consumers(PCE, PMI) has an influence on the consumers' perceived equity of Fair Trade products. The results of this study will provide an opportunity to theoretically explain the gap between consumers' attitudes and behaviors of Fair Trade products, which is a part of ethical consumption, and provide important implications for the establishment of marketing strategies.

본 논문은 불어 명사의 의미 통사적 분류와 관련된 '대상부류(classes d'objets)' 이론을 바탕으로 한국어의 "크기" 명사 부류에 대한 의미적, 형식적 기준을 설정함으로써 자연언어 처리에의 활용 방안을 모색하고자 한다. 한국어의 일부 명사들은 어떤 대상 혹은 현상의 다양한 속성이 특정 차원에서 갖는 규모의 의미를 표현한다 예를 들어, '길이', '깊이', '넓이', '높이', '키', '무게', '온도', '기온' 등이 이에 해당하는데, 이들은 측정의 개념과도 밀접한 연관을 가지며, 통사적으로도 일정한 속성을 공유한다. 즉 '측정하다', '재다' 등 측정의 개념을 나타내는 동사 및 수량 표현과 더불어 일정한 통사 형식으로 실현된다는 점이다. 본 논문에서는 이러한 조건을 만족시키는 한국어 명사들을 "크기" 명사라 명명하며, "크기" 명사와 특징적으로 결합하는 '측정하다', '재다' 등의 동사를 "크기" 명사 부류에 대한 적정술어라 부른다. 또한 "크기" 명사는 결합 가능한 단위명사의 종류 및 호응 가능한 정도 형용사의 종류 등에 따라 세부 하위유형으로 분류할 수도 있다. 따라서 주로 술어와의 통사적 결합관계를 기준으로 "크기" 명사 부류를 외형적으로 한정하고, 이 부류에 속하는 개개 명사들의 통사적 세부 속성을 전자사전의 체계로 구축한다면 한국어 "크기" 명사에 대한 전반적이고 총체적인 의미적 통사적 분류와 기술이 가능해질 것이다. 한편 "크기" 명사에 대한 연구는 반드시 이들 명사를 특징지어주는 단위명사 부류의 연구와 병행되어야 한다. 본 연구는 한국어 "크기" 명사를 한정하고 분류하는 보다 엄밀하고 형식적인 기준과 그 의미 통사 정보를 체계적으로 제시해 줄 것이다. 이러한 정보들은 한국어 자동처리에 활용되어 "크기" 명사를 포함하는 구문의 자동분석 및 산출 과정에 즉각적으로 활용될 수 있을 것이다. 또한, 이러한 정보들은 현재 구축중인 세종 전자사전에도 직접 반영되고 있다.teness)은 언화행위가 성공적이라는 것이다.[J.

This paper attempts to explore the relation between health care availability and child mortality among ethnic groups with different cultural traditions of sex preference. Micro-data from the 1990 Census of China for Yanbian and Xishuangbanna Prefectures are used. Based on the analysis of data for Koreans, Hans, and Dais in these prefectures, a new model explaining the relation between sex preference, health care. and differentials in child mortality is proposed in this paper. In societies, where health care is easily available, the level of child mortality is not likely to be a function of sex preference. In societies where there is little availability of health care, members of ethnic groups with strong sex preference do whatever possible to assure survival of their children of the preferred sex. But actions to assure survival of children of the sex not preferred by their parents depend on the costs involved and other considerations. Therefore, the level of child mortality for the preferred sex is likely to be substantially lower than that of the not-preferred sex. However, as availability of health care improves and the cost of obtaining health care becomes lower, survival of children of the not-preferred sex are likely to improve. It is generally agreed that Koreans and Hans show strong son preference, while Dais have cultural traditions of daughter preference. In Yanbian, where virtually all children receive health care whenever it is needed, Korean females and Han females show lower child mortality than their male counterparts, although the difference is not found to be significant for Koreans. In Xishuangbanna, where there is little availability of health care, Dai males show markedly higher child mortality than Dai females, and Han females have higher child mortality than Han males. However, small improvements in the availability of health care in Xishuangbanna translate into substantial improvements in survival of male children for Dais, and survival of female children for Hans.

The general tendency of approach to Korean Design History has been focusing its primary interest on the grand story in relation to the problems of modernization in political, economical and social aspects of Korea. In the discourse of modernization, however, there are two sides immanent in the modernization: there is the formal, institutional and authoritative modernization developed inside the capitalistic mode of production and the informal, individual and cultural modernization manifested in the mode of everyday lives. Especially, despite the viewpoint of the latter being embossed as an alternative approach in various areas including the academic world of history since the collapse of socialism, the historical recognition of the phenomena of modern design by the Korean design historians is more like the 'history from the above' that exists at the level of the discourse outside the reality rather than the 'history from the below' that exists within the ordinary life. To grant a sense of balance in such frame of historical understanding, it requires the restructuring the design history of Korea through the cultural perspectives from having the representation of mundane lives realized by the voluntary design activity of the common people as research subjects. One of the methods to acquire an answer to such problem is decoding, in the manner of 'cultural history', the life-long domestic artifact made by Madame Yang, Gap Jo (currently 87 years of age) who is a model of typical Korean mother. Through the historical rumination on the traces of unpretentious lives of the people that has been buried under the grand narrative of the Korean Design History, a new era aimed for the historical prospect of Korean design as cultural history will be possible by excavating the petit yet multi-layered meaning of Korean designs.

Currently, infertility and artificial insemination have increased. However, there is no detailed legislation about this. In this study, I'll consider the legal status of artificial insemination child. Through the examination of the overseas legislation, we may get the reference of the future legislation. If we consider the increasing of infertility, artificial insemination should be allowed. And due to the well-being of artificial insemination child, such as the United States and France, the artificial insemination child should be regarded the legal child of the infertile couples. When the contradiction between the subject's basic rights has occurred, we need to consider the welfare of the child preferentially. Because the artificial insemination child has no selection of opportunity in birth, unlike adults who select the artificial insemination in their own free will. The development of biotechnology should be for the treatment of human. But creation and improvement of human must be prohibited. In addition, the social investigation of recognition about A.R.T. and general public administrative legal regulation should be made. There is a need for balanced discipline through a multi-disciplinary research. This study may be providing a legal interpretation criteria of other biotechnology researches.

Medical practices such as surgery often need to accompany anesthesia, which frequently causes medical accidents. In order to determine whether a medical accident related to anesthesia was caused by a doctor's fault, it is necessary to understand what is the duty of care required for the medical staff such as a doctor through all stages of anesthesia. This paper analyzed Supreme Court decisions since 1990s and recent lower courts' decisions in order to understand standard of care with respect to anesthesia. While numerous medical accidents were related to inhalation anesthesia in the past, it turned out that recent medical accidents were often related to the use of intravenous or local anesthetics. In particular, legal disputes with respect to medical accidents related to propofol have considerably increased since 2007. However, because Supreme Court decisions as to anesthesia accidents are mostly related to inhalation anesthesia, they seem to be insufficient to set standard of care as to other types of anesthesia accidents. In light of the fact that medical accidents related to the use of propofol have been increasing, it is critical to establish and maintain clinical guidelines on the use of each anesthetic in the medical field. However, The Courts can present the standard of care suitable for medical reality to serve as a compass for medical practices.

Our society's modernization created many opportunities for us to need a private investigation service system. Variation of international environment due to joining in the OECD, opportunity of individual legal, collect evidence during judgement, prevention of damage criminal, security of business in company, free trade economy's system etc and don't need to enumerate how important of introduction of private investigation service system. In addition to there are lots of objection opinions, such as possibility of person's private life, invade of lawyer's area, confliction with investigation team, gap of wealth and poverty that make preponderance of information. So this research can be considerate from objective opinion, and can obtain conclusion just like below. First, private detective agencies that encroach on the individual rights will naturally deteriorate after the implementation of private investigation service system. Through this, the probability of civil rights encroachment will be lower, and for this to happen there needs to be a thorough maintenance of the system. Secondly, mutually beneficial solution should be found not by a conflict between two sides. Detective business sector should not cause social confusion from conflicts with other investigation organization such as police, or investigators, rather, it must get on the demand of the diversified citizen and maintain the diverse sector inter-cooperate right, and to do that law and institution must be made for the base. Thirdly, investigation used depending on the gap between wealth and poverty does not mean the actualization of the rights and interests of the citizen. If the duty of investigation sector is to find the evidence and collect or manufacture of the evidence, then the problems which the nation can't handle will be more enlarged and then finally end up with strengthening the capability of national public security demand.

This study explores the political parody, which has become an active art form in order to express Korean Internet users' political practices, especially, during the politically turbulent periods from the presidential election of 2003 to the recent candlelight vigil protest of 2008. This study investigates the rise and fall of a parody culture by online users from the mid-2000s, and also examines aesthetical aspects of parodic artworks relying on amateurism culminated in 2004. Specifically, the current study questions an aesthetical lack shown in 'appropriation', by which most of the online users simply produce imitations of original image. This study rather notes 'photomontage' as an aesthetic prototype, the political aesthetics made by John Heartfield, through which this study intends to observe how his aesthetical legacy of political art could be realized in the contemporary form of political parodies produced by online users. The present paper concludes that online users' political participations in producing critical works of art could allow us to negate the dichotomy between the elite and the mass, professional artists and amateur parodists, and a radical politics and the politics of style.
