The material characteristics of Chos$\breve{o}$n whiteware were investigated by analyzing and comparing the body and glaze compositions of whiteware shards excavated at the Kwangju royal kilns, Ch'unghyodong, and four other local-level kilns. In Korea, the rise of whiteware technology began in the early years of the Chos$\breve{o}$n dynasty, when the indigenous tradition of Kory$\breve{o}$ celadon was strongly influenced by the whiteware aesthetics of the Chinese Ming dynasty. The Kwangju royal kilns eventually made hard-textured whiteware of a quality equivalent to that of the Chinese by using type of porcelain stone that contained slightly less $Fe_2O_3$ and $TiO_2$ and slightly more $K_2O$ than that used for celadon. In contrast, the potters of Ch'unghyodong achieved the same level of quality by finding and using a totally different material: kaolinitic clay. The porcelain stone used at the Kwangju kiln was commonly found in Korea and south China, whereas kaolinitic clay (which has a high aluminum content) was typically found in north China, and was only rarely used in Korea. The flux component of the glaze compositions was mostly limestone, first in burnt form and later in crushed form, and the clay component was often glaze stone, which was a finer-grained porcelain stone with a higher proportion of feldspar. In the future, this comparative analytical study of Korean whiteware components should be extended to the $18^{th}$- and $19^{th}$-century kilns that are currently being excavated at a rapid pace.

With the rapid change in technology, it is important to create business opportunities from technology. Many leading companies have tried to improve their competence from capturing those opportunities, which is called TOD (Technology Opportunity Discovery) activities in this research, by identifying emerging technologies or assessing economic and market potential of technologies. Academics have also been interested in the TOD activities but most of the previous studies have focused on developing methodologies or guidelines for TOD. Little effort was given to understanding the current status of TOD activities, which is indispensible to develop effective methodologies for TOD. Therefore, this study aims to investigate the current states of TOD activities, particularly focusing on SMEs, which are the main actors of national innovation system. For the purpose of investigation, firstly, TOD process was defined, and then, based on the process, three main activities of TOD, which include identifying the motivation of TOD, collecting information for TOD, and analyzing the collected information activities for TOD, were examined using a survey method. Finally, the analysis results were used to understand the SMEs' needs and difficulties on TOD activities. Research findings are expected to provide useful information for the future studies on TOD and also can be used to develop a policy for SMEs.

This study was started under the judgement that reviewing $\ulcorner$A Survey Report of Korean Architecture$\lrcorner$, which contains photographs and drawings by Sekino Tadashi and which was also made under the order of the Japanese government(1902), would make it possible to consider in detail the status of Korean buildings in the period of the Korean Empire. The focus of the study. was put on three main parts of the temple, especially the central parts. The photographs and drawings as mentioned above showed that changes in the layout of buildings in the central part of the temple were made between the period of the Korean Empire and that of Japanese occupation. Thus the purpose of the study is to investigate when changes in building layout in the central part of the temple were made and what made such changes to be caused, obtaining information necessary for future changes in the precincts of the temple. Results of the study can be summarized as follows. First, 'Seonchal Daebonsan Beomeosa feonkeongdo' and 'Gyeongsangnamdo Dongraegun Beomeosa Geonmul Jeondo' were made in a same period. While, 'Chosun Gojeok Dobo', published by the government-general of Chosun, was a collection of photographs taken by Sekino Tadashi for about 30 years from 1902 to 1933 under the order of the Japanese government. But there were few changes in the building layout of the temple shown in the three materials. Second, one of the photographs and drawings made since 1933, not contained in 'Chosun Gojeok Dobo', and discovered by this researcher was 'Seonchal Daebonsan Beomeosa Annae' which was published by the temple itself after national independence from the period of Japanese occupation, indicating the main reason of changes in building layout as mentioned above. In conclusion, the layout of buildings of the temple began to be changed on a large scale, with so-called 'Cheyongseol' ignored, when Buddhist monk Cha Woon Ho established a 7-storied sarira tower to the left of the main building in the center of the upper part in 1936. In addition, the axis line connecting between Hwaeomjong and Seonjong was also changed at that time.

The purpose of the study is to investigate infection management status of long term care hospitals and infection prevention knowledge of caregivers. This is descriptive study to investigate the factors affecting caregivers' infection control performance in long term care hospitals. The data collection period was from August, 2018, and a total of 197 caregivers from 8 long term care hospitals. The data analysis were done Win SPSS 20.0 with t-test, ANOVA, pearson's correlation coefficient, and hierarchical multiple regression analysis. Infection prevention knowledge was positively correlated with infection control performance (p=<.001). The factors influencing performance in a long term care hospital caregivers were over seventy years old (t=2.50, p=.013), eight-hour working time (t=-2.62, p=.010), nursing staffing First grades (t=2.48, p=.014), and infection prevention knowledge (t=2.96 p=.003), which explained 12.9% (F=6.70 p<.001). In summary, we recommend to develop infection education interventions to improve caregivers' infection control performance in long term care hospitals and to improve of the function in long term care hospitals.

This study aims to share a methodology for locality reproduction by concretely explaining the theoretical model, procedure, and practice of constructing the Port of Busan Image Digital Archive, based on the photographic and postcard images of the Port of Busan, the representative place of Busan. Among the open-source record management programs, Omeka was chosen in implementing the digital archive because of its suitability for image exhibition. After establishing the principles for archive implementation in accordance with the purpose of the archive, a basic investigation was conducted for the record collection. With the consent of the individuals and institutions that possess the related records on the Port of Busan, such as the National Archives of Korea, the Busan Museum, and the City of Busan, original image artifacts were thus collected. The collected artifacts were then described using the Dublin Core metadata and categorized by time period. The Port of Busan was classified through four distinctive spatial characteristics (transportation, historic, industrial, and living spaces). A total of 11 themes for the exhibition was then suggested. The Busan-Shimonoseki Ferry Boat was chosen as an example exhibition of transportation space.

This study aims to calculate reliable sectional travel speeds with the consideration of the characteristics of the probe data collected in the interrupted traffic flow. First, in order to analysis the characteristics of the probe data, we looked into the distribution of the sectional travel times of each probe vehicle and compared the difference in the sectional travel speeds of each probe vehicle collected by DSRC. As a result, it is shown that outliers should be removed for the distribution of the sectional travel times. However, The comparison results show that the sectional travel speeds from the DSRC probe vehicles are not significantly different. Finally, based on the distribution characteristics of the sectional travel speeds of each probe vehicle and the representative values counted during a collection period, we drew the optimal outlier removal procedure and evaluated the estimation errors. The evaluation results showed that the DSRC sectional travel speeds were found to be similar to the observed values from actually running vehicles. On the contrary, in the case of the sectional travel speeds of intra-city bus, it was analyzed that they were less accurate than the DSRC sectional travel speeds. In the future, it will be necessary to improve BIS process and make use of the travel information on intra-city buses collected in real time to find various ways of applying it as traffic information.

Accidents are important causes of death and disability in children. They also have enormous financial implications. Young children become an victim of accidents easily because of their physical fragileness and their coping behavior being vulnerable to any actions taken by accidents. Once they have a accident, the children whose not fully developed, suffer from devastating long-term after-effects. Lee, Lee, Kang and Han(1995) reported that ninety percent of accidents can be prevented. But there is no national system to manage, evaluate and analyse the information about child accidents, even though it is necessary for accident prevention policies and health promotion of the general public. The purpose of the study was to determine how often children have accidents and define the accident prevention strategies in children. The investigator conducted a descriptive study by performing the surveys, interviews, and workshops for the 2,458 young children, 10 teachers, and 1,494 parents. The data collection for the study began on September 2000 and completed on April 20, 2001. The analysis of the data was done with Window SPSS 10.0 for descriptive statistics. Among those children, 1,298 children(52.8％) injured from accidents. The children who had accident answered that they injured from traffic accident(27.3％), inside the home(26.3％), on the playground(17.0％), during playtime(13.6％), in the school(5.9％) and food poisoning(7.1％). To define accident prevention strategies for the school children, the parents and the teachers who had a special interest in this topic formed a special task force under the guidance of the investigator. The team was charged to prepare the basis of content materials by identifying the problems, setting standards for the program, prioritizing the process, and selecting the methods of implementation and evaluation. Eight issues and concerns identified by the team were: 1)allowing young children to learn undesirable habits and behaviors that would bother others without knowing; 2) not guarding young children from car accident; 3)unattended accident at playground; 4) considering home places safe; 5)unattended accident at school. These issues were found to be coinciding with the actual child accident cases occurred recent years in Korea. Greater efforts are required to reduce unnecessary deaths and disability from childhood accidents. This study gave a very useful and important data to prepare accident prevention educational program and to prepare accident prevention strategies.

Jigangkooksa's Monument at Beopchonsa is a monument representing the Goryeo Era, registered as the National Treasure No. 59. Haerin was a descent of a small regional clan, who overcame a number of challenges to become the leader of the nation at the age of 75. The tower and monument built after his death are among the finest works of the Goryeo Era. The Yongwha-world of the Jigangkooksa's Monument is the expression of a new utopia, which cannot be found in numerous Buddhist arts including Buddhist holy picture's art or other Codex. After passing through the pillar of cloud where 4 heavenly birds play, the new world of vault unfolds. Below are the 13 mountains which stand for 13th Heaven. In the center stands Tusita, the sky. On the top of Tusita is a Nagapuspa. The Nagapuspa in general has wooden pillars of treasure dragon patterns with dragonhead-shaped flowers on top. On the bottom, indrajala hang down. The Yongwha-world of the Jigangkooksa's Monument is carved with patterns related to Maitreya entering Nirvana. Jigangkooksa was active in the Moonjong Kingdom, the most prosperous times of the Goryeo Era, and led the publication of the Buddhism's Collection of Sacred Writings, the holiest work of the Goryeo people. At the time, people have offered on his tower a picture of him as the owner of Yongwha-world, with the utmost respect. This was the ideal utopia perceived by the people of Goryeo.

This study was conducted to elucidate the seasonal prevalence of adult mosquitoes and occurrence of anopheline larvae in Gimpo, Gyeonggi province, Republic of Korea. Sampling of adult mosquitoes was carried out 18 times from May to September in 2008, using light traps at six sites. A total of 48,919 individuals belonging to 16 species and 8 genera were collected. Aedes vexans nipponii (43%) was the most frequently collected, followed by Anopheles sinensis (34%) and Culex tritaeniorhynchus (14%). The seasonal prevalence of anopheline mosquitoes had a different occurrence compared to that of Cx. tritaeniorhynchus. Anopheline larvae were collected using a standard dipper (size = of 350 ml) at eight habitat types of 203 point locations. Anopheline larvae were confirmed from 138 points (63%). The average larval population per dipper was highest in the lotus plantation (6.9 individuals), followed by irrigation channel (4.5 ind.), dropwort field (3.4 ind.), fallow field (3.1 ind.), paddy field (1.8 ind.), swamp (1.4 ind.), and stream (0.2 ind.). There was no significant relationship observed between larval density and DO, pH, salinity, or distance from blood meal hosts (cowshed, pigsty, chicken-house). In the results of average nearest neighbor analysis (ANNA), the distribution of whole points for mosquito larval collection was clustered, and points with over 4.0 larvae per dipper were randomly distributed. Within the study area Haseong-myeon, those points where over 3.0 larvae were collected were of a dispersed distribution.

The purpose of this study is to identify a potential user's need for use and operational of the elderly day care center and to identify the problems and suggest development directions. The data collection was conducted on 320 ordinary people living in J-do through a questionnaire, and sought to understand the operational status of in-depth interview institutions for the heads and employees of six center. As a result of the analysis, a potential user's ware not aware of the functions and specific roles of day care center, the cost of facilities was covered by the government, and that facilities and the environment were important factors when using the center. In-depth interviews show that the current policy or system is far from reality and does not fit the status or role of the workers and the operational status of the agency, requiring the re-establishment of the on-site system. Based on the research results, the development direction of day care facilities requires active promotion and strengthening of family support for improving and enhancing awareness of day care facilities to citizens at the national level. Second, the quality of nursing services should be enhanced through improvements in facilities and the environment that reflect users' needs. Third, The government should improve the quality of nursing services by improving the poor employment conditions and treatment of workers to fit the reality.
