The purpose of this study is to find the development of the special security business plan based on the problem that guards are now aware of special security service. In order to achieve the objectives of this study, we analyzed the data after expert survey and interview conducted by seven experts engaged in special security services more than 10 years. The guard who perform special security service proposed a development plan of special security services as follows. First, the current education system for new employees' training is required to improve the educational program of 60 hours in subjects related to special security duties by reorganization. Second, the special security service training for guards also appropriate to switch to 9-hour training program for three months through an educational organization controlled by country. Third, the special security guards should be proceeding the practical programs required in the field and quality education in the different section by competent and professional instructors. Fourth, the retirement age for special security guard stipulated in the Security Services Industry Act that needs to be readjusted upward by considering the social environment. Sixth, there needs to be organized the Special Security Association for development associated with the special security service and to protect the rights of special security guards.
The purpose of this study is to investigate about security service history as enlightenment period from the provisional government to 1920s. This study used materials by historical facts for the regulations and books in provisional government, newspapers in 1920s. There are four parts conclusion of this study: police department of provisional government, security service agency in the provisional government, security service agents of an independence movement, the general society of Korea. Firstly, Kim Gu, a prominent Korean nationalist leader, was understand of security service which was to protect provisional government from the enemy. So, Kim Gu participated in training of security service agents in the police department of provisional government. Secondly, there was security service agency in the provisional government. In 1920s, security service agency and agents appeared for the first time in regulations of the provisional government. At the beginning of the security service agency's appearance was influenced on background and circumstances for Korean independence activist who helped the independence of Korea from Japan. Thirdly, security service agents leaded an active for independence movement of the private organizations in 1920s. They carried on an independence movement in defiance of Japanese coercion as nationalist in Korea history. Fourthly, security service came out the general society of Korea in 1920s. The security service was not just for safety, but also for its security system and peace of mind, which were influenced by the political situation, social environment in 1920s. For the this reason, now security service has safety perception in Korea despite the historical progress.

This paper presents the impact of partial shading on $CuIn_xGa_{(1-x)}Se_2(CIGS)$ photovoltaic(PV) modules with bypass diodes. When the CIGS PV modules were partially shaded, the modules were under conditions of partial reverse bias. We investigated the characterization of the bypass diode and solar cell properties of the CIGS PV modules when these was partially shaded, comparing the results with those for a crystalline silicon module. In crystalline silicon modules, the bypass diode was operated at a partial shade modules of 1.67 % shading. This protected the crystalline silicon module from hot spot damage. In CIGS thin film modules, on the other hand, the bypass diode was not operated before 20 % shading. This caused damage because of hotspots, which occurred as wormlike defects in the CIGS thin film module. Moreover, the bypass diode adapted to the CIGS thin film module was operated fully at 60% shading, while the CIGS thin film module was not operated under these conditions. It is known that the bypass diode adapted to the CIGS thin film module operated more slowly than that of the crystalline silicon module; this bypass diode also failed to protect the module from damage. This was because of the reverse saturation current of the CIGS thin film, $1.99{\times}10^{-5}A/cm^2$, which was higher than that of crystalline silicon, $8.11{\times}10^{-7}A/cm^2$.

The Land Suitability Assessment is mandatory by National Land Planning and Utilization Act and the results are considered in the establishment of urban master plan and urban management plan. The study aims to examine whether the application of Land Suitability Assessment in developed urban areas is appropriate. A simulation analysis based on the Seoul's data of environmental ecological, physical, and spatial characteristics was conducted on urban green, the only applicable land for the assessment in Seoul. The results of the assessment shows that all pieces of lands in urban green is suitable for 'development'. This conflicts to the purpose of land use of urban green which needs to be conserved to protect the natural environment and landscape, animals and plants, environmental pollution, and urban sprawl. In the analysis applying optional indicators such as the distance from the area of Biotope Class 1 to prevent this conflict, the results shows little difference. This supports the necessity to review this regulation including an option to exclude developed urban areas such as Seoul in the assessment.

Glaux maritima var. obtusifolia is distributed in very limited areas in South Korea and thus designated and protected as an endangered species. This study aimed to identify the diversity of vegetation in the Dangsa coast wetlands, the southern limit of G. maritima var. obtusifolia and to assess determinants of the vegetation and the importance of habitats. The phytosociological method of the $Z{\ddot{u}}rich-Montpellier$ School was used for vegetation classification and mathematical and statistical analyses were also conducted to analyze environmental factors and their relationship with the vegetation. The results of this study showed that there were 4 vegetation units in the Dangsa coast wetlands: Glaux maritima var. obtusifolia-Triglochin maritimum community (included three subcommunities), Puccinellia nipponica s.l. community, Beckmannia syzigachne-Isachne globosa community and Typha laxmannii-Phragmites communis community. It was also found that major determinants of the vegetation include moisture environment, soil depth, water level disturbance, vegetation height, community structure, etc. Glaux maritima was identified to grow most dominantly in the typicum subassociation of Glaux. maritima var. obtusifolia-Triglochin maritimum community, and the species compositions and dominant situations were observed to be similar to those in the southern limit in Japan, adjacent to South Korea. The assessment results indicated that the Dangsa coastal wetlands have a significant meaning from phytogeographical and syngeographical aspects, and contribute as a shelter for diverse species. It is required to establish conservation strategies to accurately determine the value of the wetlands of the Dangsa coast from various perspectives, and to protect and manage them.
On December of 2003, IMO's $23^{rd}$ Assembly discussed 'Guidelines on places of refuge for ships in need of assistance' At the discussion, Res. A.949(23) has been selected to appoint recommended place of refuge for countries signatory to the IMO Convention. IMO defines "Places of Refuge" as a places where a ship in need of assistance can take action to enable it to stabilize its condition and reduce the hazards to navigation, and to protect human life and the environment. Appointing and managing a Place of refuge can be a delicate problem because of its close connection to each country's coastal and environmental protection policies. However, in case of marine accident, the appointment or management of the place of refuge has a potential to avoid further damage and reduce to the minimum any environmental and estate losses. Currently a number of foreign countries, designated and operated a place of refuge. But, place of refuge selected method criteria were different by country and also does not have any standardized designating place of refuge model. Therefor, this study suggested the model of assigned places of refuge according to objective indication in order to assign reasonable and efficient places of refuge in domestic waters in the future by investigating and analyzing imported facts in considering the assignment of places of refuge in foreign countries and describing these imported data into quantitative value. In designating the model place of refuge, the final place of refuge location was presented by evaluating the probability of marine accidents, analyzing the location, and evaluating the supporting establishment.
Living spaces are the results of social environment and also the reflection of the viewpoints by their residents toward human culture and society. Therefore, in studying living spaces, the true essence of the spaces could be easily distorted when cultural and symbolic motives and values are disregarded and only their apparent characteristics are looked into. Hence, it's necessary to simultaneously understand both physical dwelling spaces from architecture's view points and social ideas, simultaneously, of people who form and interact with the spaces. Hence, this paper tries to study housing religion which is one of shamanistic religions which, in turn, have been the fundamental element of ancient religions and came into existence on the basis of dwelling spaces. This study presumes that house religion may have been permeated with its creators' ideas about living and those ideas could be one of those factors which plays a role in organizing of dwelling spaces. As such, with these prior analyses, this thesis attempts to understand the meaning of various dwelling spaces via the characteristics and functionalities of various house spirits which are mentioned in a local house religion and also will find out spatial harmony of Korean traditional living spaces by way of corelations among living spaces, people, and personalized house spirits. Almost all traditional Korean houses have assigned a house spirit to their individual dwelling space. This means a traditional house was considered as a scared space in a secular world called human society and the space was actually intended to protect sacredness of dwelling places from earthliness outside. So when the hierarchy of house spirits in housing religion is projected to a Korean traditional house, it can be shown that a dwelling house as a building was personified to a respectable human status. In other words, it can be concluded that each space was synonymous with a dwelling place for each house spirit and was considered a sacred godly place. In a nutshell, not only each space in a Korean traditional house was a physical and functional space, but also it formed a scared spatial place along with the concept of house spirits intending to ward off disasters and enjoy a comfortable life through those religious symbols and meanings. Housing shamanistic religion which has long been existing with residents and their lives is seeped with the viewpoints of the residents toward life, and hence understanding the meanings and organization of Korean traditional housing can reveal commonly practiced principles of spatial organization of the traditional houses. Therefore an analysis of Korean traditional housing on the basis of humanistic social ideas will help learn Korea's traditional houses which need to be understood in various methods.

The objective of study was to protect seabird breeding site and vegetation restoration of Chilbal and Sokugul island in Shinan county Jeonnam province, April and December 2011. We analyzed the soil properties according to the dominant communities and environmental gradient. As a result, It was highly analyzed to moisture content, organic matter, salinity, total nitrogen in Commelina communis community and low analyzed in Achyranthes japonica community. Carex boottiana community which mainly used as a seabird habitat has a wide range and Achyranthes japonica and Artemisia princeps community was narrowed to soil properties. Soil pH of Carex boottiana community in Sogugul island was the lowest on 3.14 and Peucedanum japonicum community was the highest. Soil moisture content and organic matter was analyzed by the high value in Peucedanum japonicum community. In contrast, Achyranthes japonica was the low value and Carex boottiana community was analyzed the highest on the salinity and total nitrogen. On the soil environmental characteristics according to the environmental gradient, The higher altitude, moisture content, organic matter, salinity and total nitrogen was the lower in Chilbal island. In the case of Sokugul island, the altitude difference did not show the characteristics of soil environmental factors for small area and low altitude. But moisture content is similar to soil property of Chilbal island. Soil property was strongly acid soil because of seabird dropping. This results will be helpful to manage the invasive plants.
Purpose: This study investigated the Korean social workers’ burn-out factors and personal traits in hospice and palliative care field, and also examined the effect and correlation between their professionality, social support and supervision. Methods: Data (N=46) from 46 social workers working at hospice and palliative care field were collected, and the data were analyzed for the inferential statistics using t-test, ANOVA, correlation and multiple regression with the SPSS 12.0 program. Results: General factors of the burn-out were age and work experience. The effect of the organization environment is greatly dependant on social support and supervision, and the burn-out were protected when workers got an emotional support from their family. For the workers with supervision, the less negative feeling, the better for the burn-out protection. Furthermore, the low burn-out was thought about when professional organization, self regulation, job vocation and autonomy were utilized. Regression analysis needed that the burn-out were protected well when individual autonomy among expertise was guaranteed. As for social support, vertical support was able to protect physical burn-out. Conclusion: The training program for social workers in hospices and palliative care field is essential to reduce and prevent the burn-out. Hospice should be more activated and a training program with up-to-date knowledge and information should be adopted.
A series of multispectral high-resolution Korean Multi-Purpose Satellite (KOMPSAT) images were analyzed to detect the geographical changes in four different tidal flats in the west coast of South Korea. The method of unsupervised classification was used to generate a series of land use/land cover (LULC) maps from the satellite images, which were used as the input of the temporal trajectory analysis to detect the temporal change of coastal wetlands and its association with natural and anthropogenic activities. The accurately classified LULC maps extracted from the KOMPSAT images indicate that these multispectral high-resolution satellite data is highly applicable to generate good quality thematic maps for extracting wetlands. The result of the trajectory analysis showed that, while the tidal flat area of Gyeonggi and Jeollabuk provinces was estimated to have changed due to tidal effects, the reductive trajectory of the wetland areas belonging to the Saemangeum province was caused by a high degree of human-induced activities including large reclamation and urbanization. The conservation of the Jeungdo Wetland Protected Area in Jeollanam province revealed that the social and environmental policies can effectively protect coastal wetlands from degradation. Therefore, monitoring for wetland change using high resolution KOMPSAT is expected to be useful to coastal environment management and policy making.
