Government organizations (including police, prosecutor, and Financial Supervisory Service) and programs to uncover or prevent from insurance crime are not well developed. However, insurance crime are increasing among not only private insurances such as life insurance, indemnity insurance, and auto insurance but also public insurances including national health insurance and industrial accident compensation insurance. The damages of crimes are serious in both economical and ethical perspectives. Insurance crime deteriorates a current account of insurance companies and the leakages due to insurance fraud worsen loss ratio. Consequently, insurance crime increases customers' costs of insurance. For this reason, insurance companies stated to establish Special Investigation Unit(SIU) to detect insurance crime and fraud by themselves. However, organizational and operational efficiencies are limited. The purpose of this study is to examine the relationship between work environment factors, perception of insurance crime and job satisfaction among Special Investigation Units. Therefore, this study investigated the perception of work environments of Special Investigation Units. In addition, this study examined how their work environments and general perception of insurance crime influence their job satisfaction. In order test the purpose of this study, reliability test, exploratory factor analysis(EFA), multiple regression were employed. The results of this study suggested that clarity of insurance company, distress/difficulty of resolve, compensation, perception of work pressure are statistically significant on jab satisfaction among Special Investigation Unit in South Korea. This exploratory study expected to contribute to understanding of Special Investigation Unit, and their insurance crime prevention system. The results from this analysis will be examined in light of previous findings and policy implications discussed.

For the elderly with declining sensory due to aging, various sense stimulation factors provided in indoor environment is desirable healing environment. This study aims to propose the direction of sensory healing environment by adapting the richness of natural environment in indoor place based on the biophilic design theory with implementation method of sensory richness environment. The healing environment was limited to the ward in the beginning, but it has widened its range to the whole place, and the lobby is considered quiet important to healing. Therefore, this study selected lobby space of geriatric hospital as study subject. As for the study method, we deducted the analytic matrix focusing on the property and elements of the direct and indirect experience of nature appearing in the biophilic design theory, and analyzed the field investigation of subject space. Also, this study paid attention to point where the hotel lobby leads the change of emotional environment, and conducted analysis and comparison by deciding this is what the hotel and geriatric hospital should direct to. As the result, the biophilic design factor of hotel is actively expressed by complex direction of various factors, but as for the geriatric hospital, it was rather passive and simple in expression. The adaptation ratio between hotel and geriatric hospital was almost more than twice times difference in average.

In general, the estimation of optimum yield for the radial collector well is determined by the empirical equation or numerical modeling, in which hydraulic conductivity of the aquifer is a main influence factor. Hydraulic conductivities of 164 soil samples collected from boreholes and horizontal wells (average length: about 50 m) installed during well construction in the Anseong stream were drawn in two-dimensional map by the Kriging method and utilized in this study. Hydraulic conductivity analyses by Representative Elementary Count (REC) indicated the average hydraulic conductivity is similar to that of the pumping test when the number of samples reaches about 1,000, which correspond to 1,000 ㎡. Pumping test was also conducted at 1 pumping well and 13 observation wells to estimate hydraulic conductivities at each observation well. REC analysis indicated that the average value of hydraulic conductivity calculated from at least four observation wells is valid as a representative value. The overall result suggested that multiple observation wells or multiple pumping-observation well systems that are located within the range of horizontal wells should be utilized to properly estimate the representative hydraulic conductivity values and the yield of a radial collector well.

Korean shipbuilding companies have taken many efforts for safety over the years by developing Health, Safety & Environment (HSE) Management Systems, Procedures, Training, and studying Programs for prevention of incidents. As a result, the shipbuilding industry has succeeded in reducing overall injury rates. Nevertheless, the industry also noticed that incident rates are still not at zero and more importantly, serious injuries and fatalities are still occurring. One factor that may be attributing to this is the lack of managing potential severity during incident investigations, most incident investigations are implemented based on the actual result. Generally, each shipbuilding company develops their customized incident investigation programs and these are also commonly being focused on actual result. This study aimed to develop a shift in strategy toward safety to classify the criteria of potential severity from any incidents and manage that to prevent any recurrence or causing any serious injuries or fatalities in the shipbuilding industry. Several global energy companies have already developed potential severity management tools and applied them in their incident investigations. In order to verify the necessity of improvement for current systems, a case study and comparative analysis between a domestic shipbuilding company and several global energy companies from foreign countries was implemented and comparison of two incident investigation cases from specific offshore projects was conducted to measure the value of a potential severity system. Also, a checklist was established from the data of fatalities and serious injuries in recent 5 years that occurred in Korea shipbuilding industry and a proposal to verify high potential incidents in the incident investigation process and comparative analysis between the assessment by appling proposed checklist and the assessment from a global energy company by using their own system was implemented. As a measure to prevent any incidents, it is required to focus on potential severity assessment during the incident investigation rather than to only control actual result. Hence, this study aims to propose a realistic plan which enables to improve the existing practices of incident investigation and control in the shipbuilding industry.

This study is based on the premise that a garden space is a place that not only requires physical labor but also encourages conversation in the gardening group. We suggest the use of urban gardens as a place to revitalize local communities by promoting people to participate in various event programs. Through the theoretical study, we set the requirements that can be applied to "urban garden events". We developed measurement items and scales to be used as variables of each construction concept. Our survey was conducted on adults aged 19 and above who visited the 8th Korean Urban Agriculture Expo. Out of total 310 copies of the distributed questionnaire, only 298 effective samples were used in the empirical analysis. We can assume that people want to revitalize local communities based on the fact that 71 (23.8%) participants said they thought the purpose of the event is to achieve unity among residents. Throughout analysis, 15 of the necessary items were confirmed and classified into two factors: image of event (Factor 1) and evaluation item (Factor 2). As a result of verifying the relationship between educational level for Factor 1, age was significant in five items and education level was significant in six items. For Factor 2, four items were effective in relation to education level, while significant results were not found in relation to age. These results are expected to be significant if the intellectual curiosity of the residents is satisfied and the demand base of the urban garden events according to the characteristics of city people is expanded. Based on this study, it is necessary to conduct research on the use of urban gardens as an event with social functions as well as various programs that can be carried out in gardens to build and revitalize the community.

This study progressed an investigation on the cause of the efflorescence phenomenon of bricks in Suwon Hwaseong Fortress, which is designated as a UNESCO World Heritage by using diverse scientific analyses. The samples were taken in Hwaseong and analyzed using XRD and SEM-EDS for the material identification of efflorescence. We observed under a polarizing microscope and measured absorption factors for the basic investigation for traditional bricks. As a result of material identification, soluble salt($Na_2SO_4$, $KNO_3$) and insoluble salt($CaCO_3$) were detected. There was no big difference between original bricks and repaired bricks under the polarizing microscope. However, in terms of the water absorption rate, bricks which were used for repair nowadays showed low water absorption rate(1%). In conclusion, soluble salt and insoluble salt appeared due to an effect of an air pollution and joint mortar. Soluble salt was removed in the rainy season, but insoluble salt was not removed. As a result of the efficiency and safety tests for chemicals removing efflorescence, chemical E is likely to be the suitable chemicals for the efflorescence phenomenon of traditional bricks in Suwon Hwaseong Fortress. In the future, consideration whether the use of lime is available or not should be studied through comprehensive researches including repair work, construction work and the environment factor with lime. Also, physical, chemical identifications of repairing bricks will be required.

The purpose of this study is to analyze the characteristics of exhibition circulation which is caused by behavioral factors of visitor's movement and spatial factors in museums. It looks into the factors under the influence with the visitor's movement. The consideration of exhibition circulation may be classified into 2 categories. one is spatial factors which can make a exhibition circulation according to the extent of exhibition space display density position of exit display style and display secenario. and another is the behavioral factors of visitor's movement according to the time speed proportion of appreciation and visiting rate. The method of analysis is statistics of investigation by following after visitors. Through this data we found out that there are correlation with two categories. Therefore each factor that makes an exhibition circulation with organic relevancy have influence on the visitor's movement directly. So appropriate to the planning of each factor can offer visitors to more effective environment of exhibition.
