  • Photovoltaic panels are hazardous electronic waste that has heavy metal as one of the hazardous components. Each year, hazardous electronic waste is increasing worldwide and every heavy rainfall exposes the photovoltaic panel to become the source of heavy metal soil contamination. the development needs a monitoring technology for this hazardous exposure. this research use relationships between SAR temporal baseline and coherence of Sentinel-1 satellite to detected photovoltaic panel. Also, the photovoltaic plant detection tested using the difference between that photovoltaic panel and the other difference surface of coherence. The author tested the photovoltaic panel and its environment to calculate differences in coherence relationships. As a result of the experiment, the coherence of the photovoltaic panel, which is assumed to be a permanent scatterer, shows a bias that is biased toward a median value of 0.53 with a distribution of 0.50 to 0.65. Therefore, further research is needed to improve errors that may occur during processing. Additionally, the author found that the change detection using a temporal baseline is possible as the rate of reduction of coherence of photovoltaic panels differs from those of artificial objects such as buildings. This result could be an efficient way to continuously monitor regardless of weather conditions, which was a limitation of the existing optical satellite image-based photovoltaic panel detection research and to understand the spatial distribution in situations such as photovoltaic panel loss.

  • The main purpose of this study is to analyze the reform of deadministration of universities in China by the Cooper's 4-dimension of education policy theory. Based on the theory, the reform of deadministration was analyzed in four dimensions(normative, structural, constituent, and technical dimension). First, in the normative dimension, the Chinese university deadministration policy is fully guaranteed by law, and mainly aimed at "modernization of education management system and management ability". Second, in the structural dimension, a highly administrative management paradigm of universities has played an important role during the early stages of higher education development, but it now becomes one of the main obstacle to its further development. However, the Chinese university de-administration policy is a policy that has taken almost 60 years. Therefore, this problem must be solved step by step. Third, in the constituent dimension, although there were some differences in the attitudes towards "the administration" and "the de-administration" of Chinese scholars, university presidents and the public(students), most of them agreed on eliminating "the administration of universities." Fourth, in the technical dimension, Chinese central government and many universities have accumulated many achievements of "the deadministration policies" in management and practice, while some criticisms are heard, either. However, I hope that all reform cases, regardless of their success or failure, will become a model for future administrative reforms.

  • This study is an analysis of Mengshan heshang analects. Mengshan heshang lived in Song(?) and Yuan(?) Dynasty and he was a Buddhist monk of Linji Chan(???). His works handed on Buddhist monks of Goryeo in the late Goryeo Dynasty. And he influenced Buddism in the early Joseon Dynasty. In Joseon Dynasty Mengshan heshang Sermons abstract was confirmed existence of 39 editions and Mengshan heshang Liudao Pushuo was confirmed existence of 24 editions. All 63 editions show that Sermons abstract and Liudao Pushuo are his representitive analects. All editions were printed in early Joseon Dynasty. At that time Mengshan heshang analects was distributed in Joseon Dynasty. Mengshan heshang analects was distributed in all over the nation as well as in Royal Family of Joseon. Also Mengshan heshang analects was published many times in the Mt. Jiri area. The names of almost engravers found on the publications of many temples. Some engravers actively participated in publishing Buddhist scriptures in particular area. His ideas were received in the late Goryeo Dynasty and the early Joseon Dynasty actively and his many works appears like this.

  • The construction phase of the construction project needs a large scale of manpower, materials and equipment. Among them, manpower is a core part for project construction. These manpower are divided into two groups. The first is the management group that manages the construction, and the second is the site technician manpower for construction work. Recently, construction company has suffering due to the insufficient supply of technician labor. Accordingly, this study will perform an empirical analysis about the construction technician. To do this, we surveyed related research trends and conducted surveys on the satisfaction of the construction technician. The result, satisfaction with pay and insurance was relatively low compared to other items. Therefore, this study were conducted in-depth interviews with technician managers in order to analyze the cause. In addition, case analysis was conducted to analyze actual working conditions. As a result, it was analyzed that the wage level and insurance system of construction technician were considerably stable compared to the manufacturing industry. The result of this study is expected to contribute to the activation of excellent technician cultivation through the change of recognition about construction technician.

  • Women have been entrusted with responsibility for pregnancy, childbirth, and nurturing by means of socially imposed 'maternity' along with their physical characteristics. Abortion too involves the bodies of women, and women are the ones most affected by it. However, women do not yet have the right of self-determination over their bodies. In the "pro-choice versus pro-life" abortion debate in South Korea, women's self-determination is often treated with less significance than the alleged "respect for life." Moreover, as Korea's declining fertility rate has become a serious social problem, women's perspectives on the issue of abortion have been sidelined. Yet even in this context, there is a double standard between the treatment of disabled and able-bodied women. The purpose of this study is to examine the issue of self-determination, especially for women with disabilities, from the perspective of a capability approach. The following three recommendations are proposed: (a) that the various contextual variables of disabled women are included in the concept of self-determination; (b) that a solid relationship between individuals and communities is established in order to ensure the realization of the right of self-determination for disabled women; and (c) that the discourse of "reproduction rights" (i.e. comprehensive rights of women with disabilities) be expanded.

  • Chungnam Basin has been known as one of the largest Mesozoic basins in Korea, filled mainly with so-called Daedong Supergroup. The basin has evolved as the Early to Middle Jurassic intra-arc volcano-sedimentary basin developed on top of the Late Triassic to Early Jurassic post-collisional basin in this area, recording evolutionary history of the Mesozoic tectonics in the southwestern Korean Peninsula. This study carries out the geometric interpretations of the Seongjuri syncline and its surroundings in the central part of the Chungnam Basin, based on detailed structural field survey. Based on its doubly-plunging fold geometry, the Seongjuri syncline could be subdivided into the southwestern and northeastern domains. On the down-plunge profiles of the southwestern domain of the Seongjuri syncline as well as the underlying Okma fold, the Okma fault shows typical geometry of a basement-involved reverse fault that propagated up to the sedimentary cover. The profiles illustrate that the Seongjuri syncline occurs in front of the tip of the Okma fault, likely implying its origin as a part of the fault-related fold system. The result of this study will provide better insight into the structural interpretation of the Chungnam Basin, and will further provide useful information for the Mesozoic orgenic events of the southwestern Korean Peninsula.

  • Government publications at public institutions are data that are intended to convey the purpose of an institution or the performance of its business to the public or inside the institution. The management of government publications has become increasingly important under the framework of laws and systems, but matters concerning the nature and value of government publications have not been carried out at records management sites. The Act focused on the archives of the six metropolitan government, and presented issues and improvement measures for efficient management of government publications. To that end, the government should maintain a consistent payment system for publications. As payment method and payment book data in government publications are presented differently by law, a system for integrated management should be established to provide brief information and original information. Second, it is necessary to establish an administrative system that meets the storage environment. The publication registration and payment book system presented by the government's publication guidelines is the central system of the National Archives and Records Service, so it is not an efficient system in the agency archives. Third, support should be provided to recognize the value of government publications and to preserve and manage them in the long term. To dispose of the government publications, a realistic classification method, integrated and controlled program should be presented, and criteria for users using the service should be provided. Fourth, it is the establishment of an integrated management system for government publications. The National Archives Service, the National Central Library, and the National Assembly Library should simultaneously build an abstract of information and original information so that they can be managed systematically and efficiently.

  • The purpose of this study is to provide the future development of the PRC Marine Corps by analyzing the changing functions via its historical development. The PRCMC is an elite regular military forces and was established by the Central Military Commission(China) in 1953 in order to project the national military power toward the enemy's territory by overcoming maritime obstacles such as seas and lakes. The PRCMC is relatively smaller personnel strength compared with the whole size of the PRC military forces. Thus its functions were limited in the areas of amphibious and land operations, island and land defense against Taiwan before the PRC pursues expanding policy toward outside. However, in the 2000s, China pursues its policy for obtaining absolute national interest so that its functions are rapidly enlarged into defense of the forward naval bases, and those for evolving its power toward outside according to not only the island territorial dispute with Japan, but also Xi Jinping's active expanding policy what we call 'the one belt and one road'. So its personnel strength is slowly increased. If the increasement of the PRC Navy and Marine Corps would develop into the level of which they can contain the status and influence of the US military power in Asia-Pacific area, it is possible that the security environment of the North-east Asia including the Korean peninsula will be fluctuated. Consequently, the ROK also needs to reevaluate the functions and the size of the joint strength of the ROK Navy and Marine Corps considering the transition of the changing security environment.

  • The purpose of this research paper is to examine, from an ethnological viewpoint, the traditional practice of using sacrificial game and domestic livestock as is often seen at communal rites in Korea. This paper also examine how the more convenient use of livestock sacrifice developed from that in which wild game were once offered, and how this change in the type of animals used affected the significance of the sacrifice. It also looks at how the use of animal sacrifice for ceremonies eventually influenced the practice of meat consumption on the part of the participants in their daily life, and how it contributed to the eventual establishment and development of livestock breeding for the purpose of meat consumption. The practice of catching wild game in the mountains for sacrificial purposes eventually gave way to the use of pasturage cattle, but it should be understood that these domesticated livestock were raised primarily for ceremonial rather than meat consumption purpose. When used for sacrifice, these cattle were not castrated, as is normally done when they are slaughtered for meat consumption, but it should not be assumed that this was done for purposes of simplification. In addition, not only rice farmers but also when enterpreneurs set up a new enterprise, animal sacrifice was viewed not only as a form of on-site purification of evil, but also served the dual purpose of enhancing their business through the traditional custom of serving meat to those invited guests in attendance. In the large-scale village communal rite of Hwaghae Province located in the northwestern part of Korea, animal sacrifice was carried out in the ritual for the Mountain God in a highly dramatic style, and suggests that it originated with the agrarian rites of the "fire-field" farmers of East Asia, which were utilized to foretell whether the coming year would be one of abundance or famine, and to the royal ceremony held on the 3rd day of the 3rd month of the lunar calendar, as well as that held for the God of the Mountains and Streams. The dramatic-style hunting rite, included in the large-scale communal ritual of Hwanghae Province mentioned previously, as well as in the Ritual of the Cow from Pyungsan, also located in Hwanghae Province, in which wild game were used as sacrifice, is significant in that it points up the changes that have occurred in ceremonial animal sacrifice. However, more research on ritualistic animal sacrifice is still called for in rites for good farming, fishing, and the variety of others that are held throughout Korea.

  • This study verified the factors influencing continuous intention to use of OTT service users through technology acceptance model and extension. For this purpose, the main results were derived through correlation analysis and path analysis using SPSS 21.0 program and AMOS 21.0 program. The summary is as follows. First, perceived ease of use was found to have a statistically significant positive effect on perceived usefulness. Second, perceived ease of use did not have a statistically significant effect on continuous intention to use. Third, the perceived usefulness has a statistically significant positive effect on continuous intention to use. Fourth, perceived innovativeness has a statistically significant positive effect on perceived ease of use. Fifth, perceived innovativeness has a statistically significant positive effect on continuous intention to use. Sixth, perceived playfulness has a statistically significant positive effect on continuous intention to use. The above results will be meaningful in that it has revealed a path to understand the extension of the technology acceptance model of OTT services and acceptance of OTT services.
