  • In this paper, We analysed the technical characteristics of a automatic identification system that will introduce in aviation and marine radio stations. IMO's Marine Safety Committee approved revision of chapter V of the Safety of Life at Sea(SOLAS) Convention in 73rd meeting. According to this, AIS will become a mandatory carriage requirement by 01 July 2002. AIS as a surveillance system continuously receives its own position from the GNSS and then repeatedly broadcasts it on a VHF data link for avoiding traffic conflicts and possible disasters. VHF data link is organized so that a specified number of time slots make up a repeatable frame. Each radio station can autonomously allocate and deallocate slots within the frame using selection algorithm which is called SOTDMA(Self-Organized Time Division Multiple Access). The results can be an aid in the continued of understanding technical characteristics for AIS as a broad surveillance system.

  • This study was conducted to find a task to adjust the conflict situation by categorizing and analyzing the recent cases of library book censorship and analyzing the field perception on the subject of library book censorship. Therefore, recent cases of book censorship were categorized into four categories: political, legal, sexuality, and sex crime. As a result of the study, 44.5% of the respondents who answered that the restriction on access to books related to sex crimes was not a library censorship or that it was difficult to judge. It showed the perception that this issue is not an issue that can be easily decided by book censorship. Meanwhile, as a result of a survey of librarians, there was an opinion that there was a need for restrictions on collecting or reading at the library site for various reasons, and eventually showed a gap from the code of ethics for librarians against all censorship, showing the need to make efforts to reconcile such conflicts in the future.

  • Objectives: The aim of this study was to examine the debate on the use of medical devices between Western Medicine and Korean Medicine, as this is one of the greatest conflicts in Korea's medical profession. Judicial precedents and interpretations of authority serve as regulations because medical affairs law states that Korean Medicine practices are ambiguous. Method: We conducted a search in the Korean RISS, OASIS, and DBPIA databases using several keywords associated with medical devices, Korean Medicine, and Korean Medicine Doctors. The search period was until November 5 2021. The retrieved papers were classified according to the selection and exclusion criteria by checking the title, abstract, and text. For precedents, searches were done regarding comprehensive legal information, etc., and in the case of non-disclosure precedents, we requested access to the precedents by web-court requests. Results: A total of 80 documents were found as a result of the search, and 13 publications were included in the study. The selected publications were classified and analyzed by this research team into Korean medicine, Western medicine, and legal or state agency research. In the existing literature and judgments, the arguments that played a major role changed depending on the time the judgment was made. "Social conventions", "curriculum", "academic principles", and "health and hygiene dangers" were the key arguments. Conclusions: Further studies will be needed that can comprehensively arrange the existing literature and clinical results, and continuous study will be needed to verify that the use of medical devices by Korean medicine doctors is helpful for prognosis and accurate treatment of their patients.

  • This study aims to review the differences in urban regeneration independently implemented by the government (Ministry of Land, Infrastructure, and Transport, MOLIT) and Seoul based on related laws and ordinances, and to draw out the implications of Korean urban regeneration's directions. The results are as follows. First, Seoul has constantly responded to the revision of the Urban Regeneration Act by adjusting and specifying the contents of ordinances, and especially, there have been efforts to enhance regional characteristics suitably for the circumstances of Seoul. Second, in the urban regeneration of Seoul, the budgets including the matching ratio of national and local subsidies shall be changed according to the standards of the MOLIT in changing designating places after the selection of the urban regeneration by the ministry, and this procedure and these implementation methods cause confusion to Seoul and local governments. Third, there were differences in the results of comparing the budgets and support methods of the "Gaggum Housing Project" of Seoul and "New Deal Housing Repair Project" of the MOLIT, which caused conflicts due to the differences in the project implementation and support standards, and the arbitrary interpretation of the guidelines. Although the urban regeneration greatly contributed to the revelation and conservation of regional characteristics, it might be necessary to establish systems that can enhance citizens' awareness and compensate the efficient contents needed for each region in the future.

  • Purpose - The study analyzed 90 online firms worldwise and observed them for ten years to investigate their investments and firm performance variabilities. This study attemped to verify the existence of agency problems in online firms. Through this, the paper intends to expand the scope of research in the fields of investment and firm value both empirically and in theory. This study also attempted to supplement the insufficient logic of previous studies by analyzing the relationship between investment and profitability. Design/methodology - In this study, the investment is subdivided into over-, under-, and neutral investments, and an empirical analysis of the firm performance was conducted. As investment generally has long-term effects, the impact of a firm's investment on future firm performance and variabilities in firm performance was considered over the short-and medium-term period. Findings - It was found that there was a negative relationship between firms with an overinvestment and future firm performance. Underinvestment has no clear statistically significant results on firm performance. This implies that overinvestment causes more reduction in future firm performance than underinvestment. It was also found that underinvestment and overinvestment significantly increased the variability of firm performance. A positive significance was found between under- and over- investment with a variability of 3 years and overinvestment with a variability of 4 years in the future. A negative relationship was found between neutral investment propensity and future performance variabilities. Neutral investment has less effect on the future performance variability of a firm than a firm's overinvestment and underinvestment. For online firms, underinvestment and overinvestment have a greater effect on the firm's future performance variability than neutral investment. Originality/value - The agency theory predicts that information asymmetry and adverse selection problems exacerbate conflicts of interest among stakeholders, thus firm performance. The study contributed to accumulating research on online firms that are currently underexplored by analyzing the investment behavior of major firms in the online industry.

  • The current smart lighting is shaped to offer the lighting environment suitable for current context, after identifying user's action and location through a sensor. The sensor-based context awareness technology just considers a single user, and the studies to interpret many users' various context occurrences and conflicts lack. In existing studies, a fuzzy theory and algorithm including ReBa have been used as the methodology to solve context conflict. The fuzzy theory and algorithm including ReBa just avoid an opportunity of context conflict that may occur by providing services by each area, after the spaces where users are located are classified into many areas. Therefore, they actually cannot be regarded as customized service type that can offer personal preference-based context conflict. This paper proposes a priority-based LED lighting control system interpreting multiple context conflicts, which decides services, based on the granted priority according to context type, when service conflict is faced with, due to simultaneous occurrence of various contexts to many users. This study classifies the residential environment into such five areas as living room, 'bed room, study room, kitchen and bath room, and the contexts that may occur within each area are defined as 20 contexts such as exercising, doing makeup, reading, dining and entering, targeting several users. The proposed system defines various contexts of users using an ontology-based model and gives service of user oriented lighting environment through rule based on standard and context reasoning engine. To solve the issue of various context conflicts among users in the same space and at the same time point, the context in which user concentration is required is set in the highest priority. Also, visual comfort is offered as the best alternative priority in the case of the same priority. In this manner, they are utilized as the criteria for service selection upon conflict occurrence.

  • This study dealt with the U.S. government's book translation project as a part of its public diplomacy to gain the Korean people's 'minds and thoughts' in the midst of cultural Cold War from the end of World War II to the late 1950s. It was found that the U.S. book translation project was begun during the U.S. military occupation of South Korea, though with minimum efforts, and reached its peak in the late 1950s, In general, the purposes of the U.S. book translation project in South Korea was as follows: to emphasize the supremacy of American political and economic systems; to criticize the irrationality of communism and conflicts in the communist societies; to increase the Korean people's understanding of the U.S. foreign policies; to publicize the achievement of the U.S. people in the areas of arts, literature, and sciences. In the selection of books for translation, any ones were excluded which might contradict to U.S. foreign policy or impair U.S. images abroad. It must be noted that publications of a few Korean writers' books were supported by the project, if they were thought to be in service for its purposes. Even some Japanese books, which were produced by the U.S. book translation project in Japan, were utilized for the best effects of the project in South Korea. It may be conceded that the U.S. book translation project contributed a little bit to the compensation for the dearth of knowledge and information in South Korea at that time. However, the project may have distorted the Korean people's perspectives toward the U.S. and world, owing to the book selection in accordance with the U.S. government's policy guidance.

  • Conflicts between humans and wild boars (Sus scrofa) have increased because of causing crop damage and appearing in downtown. Management to reduce population size has mostly been implemented on pests, but knowledges about ecological values are very rare. Rubbing trees by wild boar was investigated to figure out characteristics and for management ecologically from July to October 2013 in a mixed forest, Geochang, Gyeongnam Province, Korea. Pinus rigida was most frequently founded, and rubbing trees, both conifers and deciduous, were mainly located in 200~600 m above sea level. DBH was no significant difference between rubbing and control trees. The use intensity of conifers was higher than that of deciduous. The coverage of foliage layers and the number of woody plants within a radius of 2.5 m of trees (rubbing and control) were also investigated and compared to determine ecological characteristics. There were 1,332 individuals founded from 25 families. In the coverage of foliage layers, the understory and midstory showed statistically significant, but not in the subover and overstory. The number of Shrubs and saplings are higher in rubbing trees than those of control, but no difference in stems. Total individuals, the number of species, species diversity index(H') within a radius 2.5 m is considerably higher in rubbing trees with high intensity than those of low intensity and control. Our results show that wild boar mainly selected and used conifers more frequently as rubbing trees. Wild boar also modified the physical environments around rubbing trees. Consequently, the positive effects such as species diversity is increase. Thus the conservation policies is required after the intensive population reduction every 3-4 years for forest ecological management rather than annual sustainable hunting.

  • Purpose - This study aims to determine the problems and limitations of the Commercial Area Activation System, which was created by a special law for promoting traditional markets and shopping districts to revitalize and efficiently manage the central commercial area in different regions. We also suggest different options for its improvement. Research design, data, and methodology - We also look into the problems of which is being promoted as a demonstration project, from the aspects of legal text and guidelines. Results - The current commercial area activation system has several problems. First, the establishment of a comprehensive basic plan on the commercial area activation is not a requirement. Second, the benefit principle should be established to prevent the moral laxity of merchants who serve important roles in the main components of the commercial area activation business when they conduct their business. Third, the current special law constrains the commercial management organization, as under the civil law yields a limitation on finding a profitable business model. Fourth, to efficiently, constructing a system that links the other central government businesses and is needed. into a regional development budget or a budget for funding small businesses that the central government can control, which is effective. Further, we offer some suggestions for medium- and long-term policies. First, an integrated coordination mechanism at the central office level should be installed while setting the basic policy to revitalize the Based on this policy, local governments need a system that exclusively based on the after establishing a comprehensive plan for urban regeneration and getting approval from the integration organization. Second, a system that enables an understanding of the problems with business promotion by monitoring the procedure of supporting projects and regularly assessing business achievements is needed. Third, a plan is needed for resolving conflicts between various interested parties that adopts the commercial area activation system for carrying out a total redevelopment of the commercial area where small shops are densely located. A market maintenance project has been conducted as a means to recover our traditional market, which was economically depressed, and to revive the local economy, but it is mostly conducted in the form of reconstruction or redevelopment and represents the interests of landowners and merchants. Thus, it is most likely to lead to a gradual disappearance of traditional markets. Conclusions - This study looks primarily into the problems that appeared in the legal text or the guidelines regarding the direction of improvement of the commercial area activation business that has been going on as a demonstration project since 2011 and suggests some solutions.

  • Purpose - The current study is to compare the cognition of stakeholders on hosting a mega sports event between Korea and the United States. In particular, to understand their cognition and perceptual conflict towards hosting a mega sports event, the study employed conflict theory. Furthermore, the study reviewed the role of social capital in the process of managing the mega sports events. Research Design, Data, and Methodology - Of homogeneous sampling, purposeful sampling method and criterion-based selection approach were used to collect interview data from key stakeholders who have been involved in hosting a mega sports events in Korea and the United States. In-depth interview transcripts were reviewed multiple tiems after transcription to extract concepts and meanings that were pertinenet to the experience involving hosting a mega sports event. Further member checks was conducted to increase the credibility of the results. Results - Results can be summarized as followed: First, stakeholders of Korea have a strong desire for positive economic effects of a mega sports event, compared to those in the United States who are more concerned in enhancing the public interests and concerns. Second, in Korea, various socio-political issues emerged at the same time and conflicts among multiple stakeholders have aggravated the situations to coordinate the issues. This was because legal system supporting socio-trust has not been established. On the other hand, major stakeholders of the United States consisted of community members who have socio-trust and networks. Thereby these social resources have been found playing a key role in building social capital that assists the stakeholders to coordinate the current issues and to solve them. Conclusions - The current study analyzed the cognition and perceptual conflict of stakehoders in a mega sports event. Social capital has beend found as a key catalyst to increase a network and cooperation among stakeholders. In order to enhance social capital in managing a mega sports event hosted in Korea, legal systems that establish networks and relationships among the related stakeholders need to be developed. Furthermore, the systematic guideline needs to be developed, organizing the sub-committees according to the types of stakeholders and the categorized common needs.
