This study examined how product characteristics and system characteristics have affected user's economic, psychological and operating satisfaction and intention of repurchase in Internet shopping malls. The results of the study were as follows: First, it showed that product characteristics and user satisfaction have significant differences; the ability to recognize economic and psychological user satisfaction differs according to the characteristics of the product. It also showed that the degree of psychological and operating user satisfaction varies according to the convenience of order and payment as well as the convenience of the system and customer service. Second, it was found that economic, psychological and operational user satisfaction had an effect on customer's intention to repurchase. This study, focusing on particular variants of on-line shopping, found that characteristics of product and system had a great impact on user satisfaction and intention to repurchase. For the firms who run internet shopping malls, therefore more attention should be directed to the convenience of products and system problems in their services since it is so easy for customers to move to another shopping site with a simple click. The result of such an investigation may lead customers to repurchase by increasing their satisfaction with the shopping services.

Purpose In this paper we verified the reliabilities of healthcare-related information provided by various users on the site of Naver Jisikin, a Korean typical search platform. Based on Q&A contents we validated answers' reliabilities to the asked questions about a lung cancer with the help of professors at a medical school. Design/methodology/approach The content analysis includes that the types of questions are classified into symptom/diagnosis, therapy, prognosis, after-management and so on. The answers contains advice, advertisement, oriental medicine, and religion as well as the above 5 question categories. The validation results of medical evidence about each answer show that only 49% among all answers have medical grounds. Findings We classified the medical grounded answers into three levels; high, medium and low. Among all answers we need to find out the answers including advertisement because the answers can be harmful to patients. We found the method to select the answers containing advertisement contents with the help of text mining research. The selection model presents high performance as 84% classification accuracy.

Correlation between community structure of herbivore and succession of macro-algal flora was examined in subtidal area of Dang-Sa Province, eastern coast of Korea from April 2008 to December 2009. For examination, the authors hypothesized that there are significant correlation between the foregoing two variables. Samplings were conducted every two months quantitatively with SCUBA diving at -3, -6 and -10 depth in the two line transects (barren and forest grounds). As results, rhodophyts was predominated in the algal flora based on the number of species and biomass; molluscs was predominated in the herbivores based on the number of species and echinoderms was predominated in that based on the biomass. There was no significant correlation between the foregoing two variables in the whole survey area and barren/forest grounds. Consequently, the hypothesis was rejected. The authors proposed that examination of correlation between the foregoing two variables should focus on the specific herbivore group(s) (e.g., amphipods) afterward.

Interpersonal trust has become essential for online communities because people have managed to be in a situation without face-to-face encounters. To identify the structural relationships between interpersonal trust and learning performance, we analyzed the relationship between two types of trust, namely, cognitive and affective, as well as two dimensions of learning performance, namely, learning satisfaction and knowledge application. We also identified the moderating role of social norms in the relationship between trust and learning performance. Results of analysis are as follows. First, cognitive trust significantly affected the two dimensions of performance. Second, affective trust exhibited a significant effect on learning satisfaction, but did not affect knowledge application. Third, the relationships between the two performance factors were significant and direct. Lastly, social norms appeared to moderate the effects of cognitive trust on knowledge application and affective trust on satisfaction. These findings suggest that organizations, which would like to optimize task-oriented performance of their learning communities, should consider linking strategies between community satisfaction and practical knowledge application.

Driven by the changes of living environment and the improvement of life quality there is a growing desire for education, culture, daily life sports, and welfare of local residents. One of the places with the facilities and space which can accommodate such desires of the residents is elementary facility within welfare districts. Additionally, elementary school facilities are assuming more roles as the center of local community, and the current education facility policies are going through a great deal of changes and diversification of school facilities due to the operation of the new 7th education courses. Therefore, the purpose of this research was to analyze school facility compounding by domestic and overseas trends and patterns in line with the trend of the social demand, and the researcher found out that in Japan the mutual exchanges among local residents are very active by compounding sports facilities, cultural facilities, lifelong education facilities, and social welfare facilities in school facilities. Therefore, this thesis researched on the space structure pattern and planning elements of compounding facilities under the premise of utilizing them for the local society reflecting the domestic trends and characteristics, and intended to propose a direction for planned research on the compounded facilities of elementary school.

Effects of forest thinning on community level properties have not been understood yet in Korea. We investigated regeneration patterns and trajectories after a disturbance by applying a chronosequence approach. Light availability, litter and woody debris cover, and species composition were determined for twenty 50 m line-transect samples representing a disturbance duration gradient (within 11 years). Environmental factors such as light availability and coverage of woody debris and litter changed abruptly after thinning and then returned to the pre-disturbance state. Although species richness was gained at shrub and ground layer in a limited way in both forests, cover of various functional types revealed diversity in their responses. Notably, Alnus firma stands exhibited a larger increment of cover in woody plants. Ordination analysis revealed different regeneration trajectories between natural and planted stands. Based on ordination analysis, rehabilitated stands showed movement to alternative states compared with natural ones, reflecting lower resilience to perturbation (i.e., lower stability). Our results suggest that community resilience to artificial thinning depends on properties of the dominant species. But to get more explanatory ecological information, longer-term static observations are required.

This study was intended to develop food and nutrition cyberclass contents for nonmajor students at university. We investigated universities which offered food and nutrition related courses in 1998 by a telephone survey in order to select the most appropriate lecture contents for the nonmajor university students. We investigated to select the most needed lecture contents for the students, 15 questions on evaluation of cyberclasses which they took. The number of subjects were 140 students of ‘C’university who registered for nonmajor food and nutrition course in 1998. Among 140 students, 80 were cyberclass students and 60 were non cyberclass students. The results of the survey were as following : Fifty-five universities out of 62 had curriculums on food and nutrition in 1998 and 36,802 students attended the non major food and nutrition lectures. 84.9% of the respondents had their own computes and the main application mostly used was word processing. Additionally, 33.3% of them used on-line communications and 81.4% of them used internet. The most interesting subject of the respondents was ‘disease and nutrition management’. The male respondents were concerned more about ‘alcohol and health’, whereas the females were concerned about ‘obesity and weight control’.

The global commercial cultivation of transgenic crops, including glyphosate-tolerant soybean, has increased widely in recent decades with potential impact on the environment. The bulk of previous studies showed different results on the effects of the release of transgenic plants on the soil microbial community, especially rhizosphere bacteria. In this study, comparative analyses of the bacterial communities in the rhizosphere soils and surrounding soils were performed between the glyphosate-tolerant soybean line NZL06-698 (or simply N698), containing a glyphosate-insensitive EPSPS gene, and its control cultivar Mengdou12 (or simply MD12), by a 16S ribosomal RNA gene (16S rDNA) amplicon sequencing-based Illumina MiSeq platform. No statistically significant difference was found in the overall alpha diversity of the rhizosphere bacterial communities, although the species richness and evenness of the bacteria increased in the rhizosphere of N698 compared with that of MD12. Some influence on phylogenetic diversity of the rhizosphere bacterial communities was found between N698 and MD12 by beta diversity analysis based on weighted UniFrac distance. Furthermore, the relative abundances of part rhizosphere bacterial phyla and genera, which included some nitrogen-fixing bacteria, were significantly different between N698 and MD12. Our present results indicate some impact of the glyphosate-tolerant soybean line N698 on the phylogenetic diversity of rhizosphere bacterial communities together with a significant difference in the relative abundances of part rhizosphere bacteria at different classification levels as compared with its control cultivar MD12, when a comparative analysis of surrounding soils between N698 and MD12 was used as a systematic contrast study.

This study was conducted to investigate the effects of road on bird community by line transect census method from May 2000 to January 2001 in Mt. Geumsan, Namhae-Gun, Kyeongsangnam-do. Canopy layer was more developed in forest area than road area. Understory vegetation of road area was more developed than forest area. Twenty six and twenty three bird species were observed in road and forest area, respectively, White's thrush and ashy minivet were observed just only in forest area, and Siberian blue robin, blue-and-white flycatcher and gold crest were in road area. The birds being to bush nesting and foraging guilds in road area were more than forest area. It is known that the road construction was negatively affected on bird community. However, road construction would be not so negative on bird community according to the results of thie study. It would be needed the maintenance of upper canopy layer and understory vegetation to reduce negative effect of road on bird communities in forest area.

Purpose: The prescription drug list for primary treatment by community health practitioners has been maintained for 30 years without any modification. Thus, this study will suggest an improvement scheme of prescription drug list for primary health care posts through an analysis of drug use in those posts. Methods: A questionnaire survey was implemented with community health practitioners from April to June in 2012. A total of 1,249 copies were analyzed. As for the databases of drug use in the integrated information, a total of 154,229 diagnoses selected in the method of stratified cluster sampling from 39 primary health care posts' data were analyzed. We consulted some experts about the prescription medication list, and referred to the medication information on-line home page for up-to-date drug information. Results: This study ultimately suggests 77 prescription drug items for primary health care posts by eliminating 35 items and replacing 1 item from the original list, and adding 4 items to it. Conclusion: This study will provide basic data for revising the prescription drug list in primary health care posts by periodically reflecting adverse effects in the existing drugs, demographic and environmental changes, and development of new drugs.
