Although reinforcement of work intensity caused by the recent prosperity of shipbuilding businesses and the steady increasing of results which produces orders has difficulties with heavy workload, unique work circumstance in shipbuilding industry where main and subcontractor do the job together is not easy to manage its safety systematically. According to KOSHA(Korea Occupational Safety & Health Agency), there were 2, 587 deaths of 95,806 disaster victims a year on average for late 6 years(2003-2008), therein 36,605 disaster victims and 646 death in manufacture where shipbuilding have 2,287 victims, 6.25% of total disaster victims and 45 deaths, 6.97%. Moreover it shows much higher accident rate in shipbuilding industry in Korea than well developed countries in this industry as Japan, Singapore, Taiwan and so it does about 3 to 10 times higher in case of death. Compared to Japan with a shipbuilding competition of orders received system, 2 times and 2.3 times higher for each and it is more than 2 times higher than accident rate of all domestic industries. These increasing of disaster result in a labor-management dispute and it is necessary that more positive efforts and investments because there occurs blind spot, neglected industry safety and health management by lack of them, Therefore this study, for the effective safety and health management of shipbuilding industry, attempts to analyze risk on kinds of ships and budget needed in safety management through classifying ships that are being made recently by three dominate major companies. For this, we carried out a survey and interview targeting experts related to shipbuilding industry and used AHP(Analytic Hierarchy Process) for result analysis. It is considered that cost of safety and health management will be spent more effectively on the results about risk on kinds of ships and budget needed in safety management in the study and that this study can contribute to decreasing disasters in shipbuilding industry.

This study aims to construct a management system of road position information as part of the build-up to a maintenance and management system of highways. First, information on the positions of the roads were obtained by a real-time kinematic satellite surveying, and then the degree of accuracy was analyzed in comparison with the data of the existing design drawings. The linear coordinates of road center line obtained by using RTK GPS showed about 7.6-13.2cm errors in X and Y directions in the case of the national road No.2 section, and about 8.4-9.2cm errors in the case of local road No.1045 section. These errors were within the tolerance scope regulated by the TS survey, and could be practically used. In the case of vertical alignment, there were about 6.2cm errors in the Z direction in local road No.1045 section. Aerial photographs are normally used in producing numerical maps, and it can be practically used because the tolerance scope of the elevation control point is l0cm when the scale of aerial photographs is 1/1000. The management system of road position information, utilizing Object-Oriented Programming(OOP), was built having the data acquired in this way as the attribute data. The system developed in this way can enable us to spot the positions of road facilities, the target of management with ease, to easily update the data in case of changes in the positions of roads and road facilities, and to manage the positions of roads and road facilities more effectively.

This study was conducted under the theory of hermitage ever built from buddhist belief. Directing to hermitages within temples of Korea Jogye Order, we focused on the layout correspondence relationship among them. and 161 hermitages were the first object of the investigation. For the accomplishment of the research purpose, the general epitome and spatial specification through various literature studies, on-the-spot survey and personal communications with a lot of priests were made. As one of the basic surveys, the foundation year were thoroughly investigated, followed by the form of building, main buddha and hermitage name. The results obtained were summarized as follows : Forty five hermitages which are equivalent to twenty eight percent of total hermitages within the parish-level temples of Korea Jogye Order, were built in shilla Dynasty and twenty hermitages that are 12.4 percent of the total were constructed in Koryo Dynasty and thirty seven percent of the total were founded during both of dynasties. This fact makes us to consider that many of hermitages in those days were constructed with the simultaneity of principal temple foundation which means hermitage had responded the spirit of the times. Every hermitage has its main Buddha and this thing happened that each hermitage enshrines its main Buddha according to the thought which was developed with the Buddhism expansion and sutra that is in accordance with their own intention. .Basically a capital temple has differed in its central sanctum in accordance with resourceful sutra, and, at the same time, twenty seven in avatamsk sectenshrine for Sakyamuni as their sanction and eight for the Merciful Goddess and 42.7 percent for Chajang's hermitages. The name of hermitage not only represents its symbol but comprises the characteristic meaning of ascetic practice. 31.7 percent of the hermitages studies was found to have the names of relating to 'ascetic practice' or 'thought' followed by the 'nature' or 'environment' to 21.7 percent.

Soil particles from rainfall flow into reservoir and give lots of influence in water quality because the geological conditions and landcover characteristics of Imdong watershed have a weakness against soil loss. Especially, reservoir slant is indicated by the main source area of soil loss. This study selected RUSLE model that could apply GIS and satellite image to evaluate the contribution rate of soil loss in reservoir slant. And we carried out an on-the-spot survey for the range, width and condition of reservoir slant that give much influences to the accuracy of soil loss. As the result of evaluation to the influence of soil loss in reservoir slant, it showed 2.64% in comparison with Imdong watershed. In view of these results, the influence of soil loss in reservoir slant was evaluated in low comparing with Imdong watershed relatively.

Objectives: Biomonitoring is used to assess human environmental exposures. Urinary biomonitoring data are typically adjusted to a constant creatinine concentration to correct for variable dilutions among spot samples. Our objective was to investigate urinary creatinine concentrations by region, gender, age and lifestyle. Methods: We studied urinary creatinine concentrations in 6,286 Koreans aged 20 years old and older who participated the fourth Korea National Health and Nutrition Survey (KNHANES IV) in 2009. Urinary creatinine concentration analysis used the Jaffe method. Results: The average urinary creatinine concentration of 6,286 Koreans was 158.99 mg/dl. The urinary creatinine concentration was significantly higher among men (184.97 mg/dl) than women (130.02 mg/dl). In both men and women, urinary creatinine concentrations were significantly different according to age group (p < 0.01). Whereas the urinary creatinine concentration of men significantly differed with smoking in adjusted comparison analysis, that of women significantly differed by education level. Ninety-two percent of urinary creatinine concentration was included within WHO guidelines effective range(30 mg/dl ${\leq}$ urinary creatinine concentration ${\leq}$ 300 mg/dl). In multiple regression analysis, creatinine was influenced by gender, age and body mass index (BMI). Conclusions: The urinary creatinine value obtained from representative samples of adult Koreans aged 20 year and older in KNHANES IV 2009 could be used as a reference value for other nationally studied surveys, such as abandoned metal mine surveys and surveys for industrial complexes.

In recent, Open markets are booming up rapidly. Open markets are one of the online marketplaces which mainly concentrated on spot transactions of commodities, and are differentiated from integrated internet shopping stores with market participants, trading rules and so on. This study investigated on factors affecting satisfaction with and preference on open markets by comparing open markets with integrated internet shopping stores, and aimed to figure out the reasons why open markets are growing up so rapidly and to forecast the future of open markets. To investigate the factors affecting buyers' satisfaction with and preference on internet shopping channel. I extracted several factors through literature reviews. The factors include the pros (cost saving and time saving), the cons (security concerns and privacy concerns), and decision making support suggested by Simon's research as well. Then, I constructed research model and related research hypotheses. To verify research hypotheses, I conducted field survey targeting on online buyers and analyzed research data using structural equation model. According to data analysis result, open markets have competitive advantages over integrated internet shopping stores with respect to cost saving, time saving, and decision making support. However, online buyers are still concerning privacy issues within open markets. In summary, buyers are considering that open markets are cheaper, faster, and more efficient internet shopping channel, compared with integrated internet shopping stores. However, open markets are required to dedicate to lessen buyers' privacy concerns to rebirth as more satisfying and preferable internet shopping channel and to prosper in the future.
