This study was intended to analyze the clothing shopping orientations and purchasing practices for men's dress shirts. It was conducted by means of convenience sampling survey with male office workers who usually wear dress shirts at work and who also live in Seoul, Geonggi, and Chungcheong area. The data collected were analyzed by frequency analysis, cross-tabulation analysis, factor analysis, t-test, and ANOVA using SPSS. The results are as follows: 1) Clothing shopping orientations were classified into six factors: brand oriented; planned; enjoying; expediency oriented; negative shopping; and low price oriented. There were partially significant differences in clothing shopping orientations according to the surveyees' age. 2) The surveyees prioritized low price and expediency in clothing shopping, but they also showed low interest in brands. 3) The criteria for purchasing were in the order of size, color, comfort, and design. There were also partially significant differences in the estimation criteria for dress shirts according to marital status and age. 4) Most respondents tended to purchase 3 or 4 pieces of dress shirts a year, paying 30,000 to 50,000 won for a piece, usually at department stores. 5) When they purchase a dress shirt, they always considers its size. In the case of married men, however, it is the laundry tag that they do care about.

This study is exploratory research on a relationship between changes in cultivated area of major crops and farm income by regions. We investigated level of income, volatility of income, and migration of suitable region by climate changes as factors influencing changes in cultivated area. Research processes are as follows. First, we classify the regions where cultivated areas are expanded or reduced through the trends of cultivated area by region and crop during recent 10 years. Second, we compare the changes in income related factors between groups during the same periods. Finally, the results from portfolio analysis show changes in stable income-based optimal crops. From these procedures, we found that the changes in cultivated area are not simply explained by income-related factors. In cases of vegetables, however, we also found that high volatility of income could contribute to reduce cultivated area of the crops. The results from portfolio analysis are not always consistent in all of cases. This means that crop selection can be decided by other factors than stable income.

Although it is about a decade since public libraries started to provide digital information services, lack of expertise for efficient service operation and restrictions related to copyrights have led to failure to obtain remarkable performances in uses. This study intends to analyze operation cases of domestic and overseas collaborative digital information services, as well as the current status of digital information services of libraries in Gyeonggido, thereby developing a collaborative digital information service model among public libraries on the level of local governments. This research then analyzed collaborative digital information service Web sites and surveys. Based on the analysis result, this study presented support of integrated search of possessed electronic information, Web database (DB), DB on original texts of regional records, online reference services, and mobile platforms as functional factors to embody a successful service model. As a system management road map, an eclectic model combining the merits of centralized and decentralized models was found to be more effective than a centralized or decentralized model in consideration of the characteristics of participating organizations.

The purpose of this paper was to investigate experimentally the steering torque characteristics of a tractor operated in various ground conditions. The experiments were conducted with the tractor reconstructed for steering torque test of the tractor at two different off-road conditions (ground-I and ground-II) and a on-road condition (ground-III), three different levels of tire inflation pressures (69 kPa, 138 kPa and 207 kPa), and four different levels of axle loads (4120 N, 4730 N, 5340 N and 5950 N). The results of this study are summarized as follows: 1) The steering torque was increased with the increase in steering angle for all experimental levels of ground conditions, axle loads and inflation pressures of tire. 2) As the axle load increased, the steering torque of the tractor increased for all ground conditions, and the increasing rate of the steering torque with the increase of axle load was greater at on-road than at off-road. 3) As the tire inflation pressure decreased, the steering torque increased. Also the increasing tendency of the steering torque with decreasing the tire inflation pressure showed that the harder the ground was, the larger the effect was. But for the soft ground condition, ground-I, no specific trend with inflation pressures was found. 4) Steering angle-steering torque relationship with ground conditions showed that the increasing rate of the steering torque was greater at on-road than off-road for small steering angle under 10 degree, and was greater at off-road than on-road for large steering angles over 10 degree.

This study was accomplished to support farmers who want to introduce Automatic Milking System. The methods of analysis is considered on it as investment analysis that NPV, ROV and FROV. As a classical investment analysis technique, NPV showed 142 thousand won on the every senarioes. On the other hands, The Real Option Analysis showed 153,826, 154,937 and 152,858 on the normal, optimistic and pessimistic senarioes respectively. it is considered as a investment analysis technique for strategic decision-making. But, it may have problem to evaluate present value of expected cash flows and expected costs by a single number. To solve those problems, this paper tried to evaluate Fuzzy Real Option Model which were jointed with a real option model and Fuzzy set model. The result of analysis showed, on respective senarioes, 153,515 to 161,489, 154,612 to 162,970, and 152,573 to 159,835 on the interval estimation. Thereby It is a more realistic in many cases.
