Purpose of this study is to classify the main industrial function by region using the factor analysis. Identified regions, Yesan-Kun area consisted of 12 Myon(towns) selected as a case study, would be conducive to establishing rural town planning reflecting their industrial characteristics. Major findings are summarized as follows. First, population of Yesan-Kun has been decreased at about 1.0% annually for the period 1970~1990, which may not meet the basic condition of sustainable regional growth. Second, economy of Yesan area, which mainly has been dependent upon the agriculture, are lagged behind because of lack of specialized manufacturing sector. Third, particularly West and East part of the region has been underdeveloped in spite of their potentiality mainly due to insufficient network of road. Based on fator analysis which classify the zones by the characteristics of industry, following developmental directions are suggested. - Yesan-Eup with a factor score of 2.85 in secondary and tertiary industry, which means functioning as a rural center should be developed to provide the residential people with basic service. - Ducksan-Myon with 2.93 factor score in tour industry is recommended to formulate leisure complex by utilizing its abundant tour resources. - Sapkyo-Eup, Goduck-Myon, Sinam-Myon, Oga-Myon Areas functioning as agricultural industry, are suggested to foster as zones specialized for the cultivation of crops and fruits. - Kwangsi-Myon and Bongsan-Myon neighboring other counties is likely to be affected by other regions' economy. These regions should be developed in association with other regions' economic circumstances. - Daeheung-Myon, Daesool-Myon and Sinyang-Myon areas, which are located southern part of Yesan County, is examined to be relatively underdeveloped area. So there are needs to make a special planning for the balanced growth of these regions.

For the estimation of prevalence state of major chronic adult disease and their relationships with drinking and smoking habits in the Korean employees, we analyzed a medical check-up data of 155,799 subjects that was accumulated during the year of 2008. In age and sex distribution of the sample, male subjects were 106,229 and female 51,827 showing the ratio of 2:1 and the majorities were 30s and 40s covering 70.7% of the total. The prevalence rates of major chronic diseases were obesity 29.8% (male 38.3%, female 12.3%), hypertension 4.1%, HBV carrier inactive 3.3%, diabetes mellitus 2.9%, hypothyroidism 1.7% (male 1.3%, female 2.4%), hyperlipidemia 1.1%, hyperthyroidism 1.4% (male 1.1%, female 2.1%), osteoporosis 1.4% (male 1.4%, female 1.4%), anemia 0.9% (male 0.3%, female 2.0%) and renal disease 0.9%. The frequency of and volume of drinking in male group were 4.6 times and 7.5 times higher than female group respectively. The 33.8% of the workers were smoking currently. In the serological tests, all the items such as AST, ALT, ${\gamma}-GTP$, LDH for liver function, Cholesterol, TG, uric acid for hyperlipidemia and BP systolic, Fasting blood sugar, BMI for metabolic syndrome were significantly higher in the more drinking and more smoking groups than other groups (p<0.001). The higher prevalence rates in male group in the liver disease seems to be strongly related with the drinking and smoking habits in male employees. We suggest that employees should rather relying on leisure or hobbies than drinking and smoking for the stress relief.

In modern society, to be achieved status as a Science edutainment experience, not just a science museum is established. It requires strategy and differentiation of a variety of entertainment, including theme parks, games, movies which are youth like. When the understanding of the audience for the principles of science to improve the use of ICT Convergence contents display, you need to take measures to increase the effectiveness of the Science Museum by giving the function of interesting leisure space in addition to the popular area of Science Education, Scientific and Cultural aspects reached. This role requires a science museum as a cultural space with the community as a chapter in science education. Science Museum is not a need to worry about what will convey to the public as efficiently as the Mecca of the educational content for the National Science Education. The analysis of the external environment, the composition will take on science education as a mecca of science education and how to combining ICT convergence technology in modern society beyond mere science museum experience and education in this study.

Rapid economic development has played a big role in the formation of the values of pluralism. On that account, the importance of leisure life has grown substantially, Such phenomenon has allowed people to travel more frequently. Hence, there has been a growing demand for accommodation. In particular, the number of design hotels with a stylish design has grown exponentially as compared with the conventional standardized chain hotels. As a result, a variety of objets have been utilized in hotel spaces for establishing a differentiated formativeness and offering a visual stimulus to users. An objet refers to an object of symbolic function. That is to say, it serves to increase cultural values by approaching arts in an ordinary environment. Distinctive objets are mainly expressed as new ideas by the emerging designers in Europe. In particular, Marcel Wanders designs hotel spaces on the basis of the emotional meaning and story of objets, thereby showing interesting elements. He brings human stories into a design by leveraging the expressional characteristics of an objet, such as the place, fantasy and story-telling, in hotel interior spaces. This allows users, who reject the stereotypes of modern functionalism, to have exotic memories by stimulating their instinctive senses. Furthermore, this can complete users as a part of an artwork by creating a huge artwork on the basis of hotel interior spaces. In this regard, I hope that the expressional characteristics appeared in the hotel interior spaces of Marcel Wanders can be utilized as preliminary data for planning design hotels in the future.

Now it became possible to make cruise ship with Korean technology, as a result of continuous research and development. However, as cruise ships are getting bigger and more popular, new cruise interior design is required to satisfy various clients' aesthetic and functional demands. Therefore, more researches for cruise interior design are needed. The purpose of this study is to analyze the characteristics of planning and design of passenger's cabins in cruise ship. The scope of this research is limited to the types in the 2004-2010 in Large Cruise Ships. Method of this study are document study and case study, in particularly, case study is conducted for the specific design methods through case analysis. The results of this study are as follow : One of the transitions in the cruise cabin designs is that cabins with balconies occupy a large portion of the entire cabins. As the functions of these balconies are diversifying, more distinctive forms of balcony are showing up. In particular, the cabins which are connected to public space differentiate themselves from those with the same rates; it meets the demands of the clients who require high quality services. In terms of cabin design, a futuristic, distinctive cabin that has incorporated will be a very important function in determining the value of the cruise ship. Based on the results of this research, application of the rapid changes in cabin design and studies about more diversified and advanced design are required.

The purpose of this study was to assess the inter-segmental trunk motion during which multi-segmental movements of the spinal column was designed to interpret the effect of segmentation on the total measured spine motion. Also it analyzed the relative motion at three types of the spine models in drop landing. A secondary goal was to determine the intrinsic algorithmic errors of spine motion and the usefulness of such an approach as a tool to assess spinal motions. College students in the soccer team were selected the ten males with no history of spine symptoms or injuries. Each subject was given a fifteen minute adaptation period of drop landing on the 30cm height box. Inter-segmental spine motion were collected Vicon Motion Capture System (250 Hz) and synchronized with GRF data (1000 Hz). The result shows that Model III has a more increased range of motion (ROM) than Model I and Model II. And the Lagrange energy has significant difference of at E3 and E4 (p<.05). This study can be concluded that there are differences in the three models of algorithm during the phase of load absorption. Especially, Model III shows proper spine motion for the inter-segmental joint motion with the interaction effects using the seven segments. Model III shows more proper observed values about dynamic equilibrium than Model I & Model II. The findings have shown that the dynamic stability strategy of Model III toward multi-directional spinal motion supports for better function of the inter-segmental motor-control than the Model I and Model II.

Sea wind isrecently drawing attraction as one of the sources of renewable energy. Thisstudy describes a new method to produce a 10 m resolution sea wind field using Sentinel-1 images and low-resolution NWP (Numerical Weather Prediction) data with artificial intelligence technique. The experiment for the South East coast in Korea, 2015-2020,showed a 40% decreased MAE (Mean Absolute Error) than the generic CMOD (C-band Model) function, and the CC (correlation coefficient) of our method was 0.901 and 0.826, respectively, for the U and V wind components. We created 10m resolution sea wind maps for the study area, which showed a typical trend of wind distribution and a spatially detailed wind pattern as well. The proposed method can be applied to surveying for wind power and information service for coastal disaster prevention and leisure activities.
