In Korea, the market size for environment-friendly agricultural products has reached a plateau, even though many Korean consumers still show a high level of preference for environment-friendly agricultural products. In order to solve this problem, some Korean farmers and marketers are starting to try to export their products to many countries, including China. China, in particular, is becoming one of the fastest rising market for Korean environment-friendly agricultural products, after the signing of the Free Trade Agreement with China. However, little research has been done or reported about the purchase behaviors of Chinese consumers. The purpose of this paper is to analyze the environment-friendly agricultural product purchase behavior (especially, mandarin orange and muskmelon) of consumers in the Chinese market and to present some useful implications for Korean farmers and marketers. Through survey in China (especially, Beijing and Shanghai) and frequency analysis, this study made the following findings: first, Chinese consumers show a very strong concern for environment-friendly agricultural products. Second, many Chinese consumers usually buy environment-friendly agricultural products more than two times per month. Third, Chinese consumers give more value to freshness and food-safety than taste when they make decisions on buying environment-friendly mandarin orange and muskmelon. These can have some implications for the exportation of environment-friendly agricultural products.

We studied the nitrogen behavior and budget of Lake Paldang from March to December 2008. The particulate nitrogen (PN) concentrations ranged from 7 to 13% of the total nitrogen concentration (TN) in the stream inflows, the downstream outflow, and the lake water. The nitrate nitrogen ($NO_3-N$) concentration ranged from 67 to 78% of the TN. In the three rivers of Lake Paldang, Gyeongan River (In3 site) had the highest average of the TN, 5.037 mgN/L, but North Han River (In2 site) had the lowest average TN, 1.683 mgN/L. South Han River (In1 site) had the average TN of 2.399 mgN/L. In the dam discharge, TN showed the average 2.063 mgN/L. In the lake water, L4 site (Gyeongan River area) had the highest average TN, 3.781 mgN/L, but L3 site (North Han River) had the lowest average TN, 1.587 mgN/L. Total input of nitrogen loads to Lake Paldang was about 30,875 ton/year in 2008. Inflow rivers contributed 30,643 ton/year (South Han River: 18,111 ton/year (59%), North Han River: 11,333 ton/year (37%), and Gyeongan River: 1,199 ton/year (4%)). The atmospheric deposition had 135 ton/year, the nitrogen release from the bottom sediments had 88 ton/year, and macrophytes had 9 ton/year. Total output of nitrogen loads from Lake Paldang was about 31,256 ton/year. The downstream from dam contributed 29,877 ton/year, and the sediment deposition was 1,379 ton/year.

Protective behavior of radiological technologists against radiation exposure is important to achieve reduction of the patient doses without compromising medical achievements. This study attempts to provide a basic model for the sophisticated intervention strategy that increases the level of the protective behavior of the technologists. The model was applied to real situations in Korea to demonstrate its utility. The results of this study are summarized as follows: First, the protective environment showed the highest relationship in the factors considered, r=0.637 (p<0.01). Secondly, the important factors were protective environment in environment characteristics, expectation for the protective behavior 0.228 (p<0.001), self-efficacy 0.142 (p<0.001), and attitude for the protective behavior 0.178 (p<0.001) in personal characteristics, and daily patient -0.112 (p<0.001) and number of the participation in the education session for the protective behavior 0.074 (p<0.05). Thirdly, the final protective behavior model by a path analysis method had direct influence on the attitude 0.171 (p<0.01) and environment 0.405 (p<0.01) for the protective behavior, self efficacy 0.122 (p<0.01), expectation for the protective behavior 0.16 (p<0.01), and self-efficacy in the specialty of projects 0.154 (p<0.01). The acceptance of the model determined by the absolute fit index (GFI), 0.969, and by the incremental fit index (CFI), 0.943, showed very significant levels. Value of $x^2$/df that is a factor applied to verify the acceptance of the model was 37, which implies that the result can be accepted in the desirable range. In addition, the parsimonious fit index configured by AGFI (0.890) and TLI (0.852) was also considered as a scale that accepts the model in practical applications. In case of the establishment of some specific intervention strategies based on the protective behavior model against harmful radiation effects proposed in this study, the strategy will provide an effective way to prevent medical harmful radiation effects that could cause severe injuries to people.

At present, the importance of organizational effectiveness is highlighted even more as business environment enters into a new type of work setting, the smartwork environment. This new type of work environment could be significantly influential in promoting organizational effectiveness of office administrators who carry out atypical types of tasks in general and are exposed to emotional labor excessively. Organizational effectiveness of office administrators could also be controlled by their concerns at work, their personal values and the increasing demand for work-life balance. The main purpose of this research is to investigate how smartwork environment perceived by office administrators is related with organizational effectiveness. In addition, this research places the focus on how concerns and work-life balance moderate the relationship between smartwork environment and organizational effectiveness. The survey was conducted among 102 office administrators, and data were analyzed by moderated multiple regression analysis method. Job autonomy of smartwork environment showed positive effect on job satisfaction, organizational commitment, and innovative behavior. IT dependence of smartwork environment showed negative effect on job satisfaction and organizational commitment and positive effect innovative behavior. It was found that concerns with impact positively moderate the effects of job autonomy on job satisfaction and innovative behavior; concerns with self negatively moderate the effects of job autonomy on organizational commitment and innovative behavior. Also, it was found that work-life balance moderates the effects of job autonomy on organizational commitment and the effects of IT dependence on innovative behavior. The result of this research can be taken into consideration when a strategic human resource development plan is prepared for office administrators in smartwork environment.

The purpose of this research is to clarify the relation between environmental consciousness and railway usage behavior. Author would locate this research on position of basic survey to promote railway use according to Low Carbon Green Growth policy in Korea. In this research, we would perform descriptive analysis using data of research on the actual condition of railway use in 2008, Daegu, and describe its relationship. In addition, we would suggest some idea about policy which can promote railway use. The order of railway choice behavior noticed in clustering of environmental consciousness was cooperative behavior type, middle type and non-cooperative behavior type. It suggests that environmental consciousness has effect on transportation choice behavior. Specially, railway improvement isn't enough to promote railway use. And, it is advisable to carry out the improvement in such a way that it may encourage the nation to move from the current environmental consciousness stage to cooperative behavior. Moreover, we assumed Binary Probit(BP) model using SP data of time or condition of transportation expense compared with passenger car and bus. As the results, modified likelihood ratio of two BP models is favorable variables. And it occurred that mode was transferred from passenger car to railway when it showed higher social environment consciousness and low selfish environment consciousness, because t-statistic which represents selfish environment consciousness showed significance in 95% confidence level. That is, it can be described that environment consciousness affect on the intention of railway use.

This study conducted a qualitative study on 23 seniors over 55 years old to understand the digital behavior of seniors in the online education acceptance environment. Grounded Theory methodology was applied to the initial enrollment behavior, login behavior, and utilization behavior of online education program. Through the process of open coding, axis coding, and selective coding, the framework in the online education environment of the senior generation was finally derived. As a causal conditions for the senior generation to participate in the online education environment, goal orientation, relationship orientation, leisure orientation and external compulsory were derived, and shadow work appeared as the central phenomenon. Also, contextual conditions resulted in social change, physical and cognitive aging, and psychological atrophy. The intervening conditions included digital device acceptance, educational attitudes, environmental factors, and self-efficacy. Based on this, the action/interactions strategy formed a positive and negative attitude toward shadow work. As a result, positive response behavior, compromising behavior, and shadow work avoidance behavior were shown. It is hoped that this study will be reflected in future researches for the use of digital devices of the elderly and the expansion of online education participation and government policy.

This paper presents the development of finite element (FE) models to simulate the behavior of diagonally stiffened steel plate shear wall systems (SPSWs) with differently shaped openings subjected to a cyclic load. This walling system has the potential to be used for shear elements that resist lateral loads in steel-framed buildings. A number of $\text\tiny{^1/_2}$-scale one-story buildings that were un-stiffened, stiffened and stiffened with opening SPSWs are modeled and simulated using the finite element method based on experimental data from previous research. After validating the finite element (FE) models, the effects of infill plate thickness on the cyclic behavior of steel shear walls are investigated. Furthermore, triple diagonal stiffeners are added to the steel infill plates of the SPSWs, and the effects are studied. Moreover, the effects of a number of differently shaped openings applied to the infill plate are studied. The results indicate that the bearing capacity and shear resistance are affected positively by increasing the infill plate thickness and by adding triple diagonal stiffeners. In addition, the cyclic behavior of SPSWs is improved, even with an opening in the SPSWs.
