This study supplies basic data to develop a greenhouse model for reducing the damage to single-span greenhouses caused by strong winds and heavy snow. Single-span plastic greenhouses are predominantly used for growing crops in Korea. Thus, the safety wind speeds for single-span greenhouses were calculated and compared with the actual wind speeds and snow depths over a period of 8 years in different regions to analyze the structural safety of single-span greenhouses. The unit wind load and unit snow load were applied to different designs of single-span greenhouse according to the cultivated crop to achieve a structural analysis. As a result, the maximum section force for the wind and snow load was greatest for leaf and root vegetables, where the safety wind speeds for single-span greenhouses according to the cultivated crop were 17.7 m/s(leaf vegetables), 20.2 m/s (fruit vegetables), and 22.3 m/s (root vegetables). Thus, the single-span greenhouses were not found to be safe for the wind load in most regions, except for Hongcheon, Icheon and Sungju. Plus, the safety snow depths for single-span greenhouses according to the crop were 8.8 cm (leaf vegetables), 9.4 cm (fruit vegetables), and 11.8cm (root vegetables). Thus, when comparing the safety snow depths with the actual snow depths, the single-span greenhouses were not found to be safe. Therefore, to improve the safety of single-span greenhouses, the structures need reinforcement by reducing the interval between rafters or increasing the size of the pipes. However, additional research is needed.

In recent years, descriptive evaluation has been gaining importance at school. The purpose of this study is to analyse descriptive evaluation items which have been made by school teachers. 300 items for regular examinations are collected from 7 middle schools (grades 1 through 3) in Gyeongnam Province. Distribution and types of items are examined to compare educational objectives of standard achievements and those of evaluation according to Bloom's revised taxonomy of educational objectives. The result shows that there exist a majority of shared subject units for descriptive evaluation. Huge difference of frequency is also found among subject units and standard achievements. Less than 65% of evaluation items are descriptive and the rest is simple completion or short answers. In addition, it reveals only 40.3% of agreement between educational objectives of standard achievements and those of evaluation items. The interviews with 27 teachers indicate that lack of ability to develop proper items and grading are the major obstacles. In conclusion, systematic training courses are to be provided in order to resolve issues over descriptive evaluation.

Seasonal occurrence of the stink bug Piezodorus hybneri (Gmelin) (Heteroptera: Penta-tomidae) was monitored at a soybean field and the campus of Gyeongsang National University, Gyeongnam. Korea, in which host plants are less available for the bug with aggregation pheromone traps of Riptortus clavatus Thunberg (Heteroptera: Alydidae) in 2004. At soybean field, P. hybneri began to be attracted to traps from June 28, earlier than flowering stage of soybean plants. Number of P. hybneri attracted increased sharply after October 11. At the campus the bugs were not attracted to traps from March 21 to October 5, but began to be attracted since October 11. Difference in the occurrences in the two sites may suggest that the stink bug immigrates actively into soybean field to find host plant. P. hybneri that had been attracted to traps since October 11 was assumed to be diapausing adults emigrating to hibernation sites. There was no difference between sexes in trap catches. The fact that P. hybneri was attracted from June to late November may suggest that the aggregation pheromone of R. clavatus was attractive to both non-diapausing and diapausing adults of P. hybneri. The aggregation pheromone traps, when baited with 16.7+16.7+16.7 mg or 7+36+7 mg of (E)-2-hexenyl (Z)-3-hexenoate, (E)-2-hexenyl (E)-2-hexenoate, and myristyl isobutyrate, attracted significantly higher number of both sexes of P. hybneri adults than the live male traps baited with ten R. clavatus males and hexane control.

The purpose of current study is to identify moderator effects of a number of use in terms of the influences of selection properties as perceived by college foodservice. This study was collected 297 survey from college students in Busan and Gyeongnam using the statistics program SPSS (18.0). Result shown that the selection properties of the institutional food service were analyzed with four elements: physical environments, service of worker, diversity of menu, and quality of food. All of the selection properties were found to have significant effects on satisfaction. Although there was no significant effect on the second stage, partial moderating effects were found in the third stage only when the interaction term of physical environments ${\times}$ the number of use is applied. Considering these results, it can be considered that a number of use of foodservice facilities are moderated by physical environments. Therefore, it implies that institutional foodservice operators should improve physical environments including interior, tableware, and cleanliness. In addition, satisfaction and preference were found to be closely related each other, which indicates that preference is improved as satisfaction increases.

In this paper, we focus the changing role of universities of University-Industry Collaboration (UIC) for enriching the regional business ecosystem network. For this research, we analyze 'Regional Innovation System(RIS)' - a specific UIC program- which provides a marketing service for firms, especially, SMEs with a specific problem by a group of consultants including CEOs, professors, and heads of regional public or private service providers. Then we have analyzed using network analysis how the business network was changed from RIS. Moreover, we will interview the participants in the important position of the network and investigate the reason for bringing a change in the network structure by using this program. This study illustrates that various types of network are formed between university and SMEs. Furthermore, the networks surrounding SMEs are extended to the other people connected to them. This means that the business network of SMEs had been diversified via the facilitation of university. This study throws new highlights on the new role for the university as a network promoter in addition to the partner as a technology-provider in the regional business ecosystem. Moreover, the network analysis between before-and-after can be used for the evaluation of the effectiveness of the various UIC programs.

Seasonal occurrence and ovarian development of the bean bug, Riptortus clavatus Thunberg (Heteroptera: Alydidae), were studied at a soybean field and an university campus in which host plants are less available for the bug in Gyeongnam province with aggregation pheromone traps in 2004. It was assumed that the bug passed three generations per year at the university campus. Adults of the 1st generation might occur from early July to early August and that of the 2nd one from mid August to late September. Adults of the 3rd generation occurred from early October to mid November, entered reproductive diapause without carrying eggs in the ovaries of females during winter, and resumed activity from late March of the next year. Full-grown eggs in the ovaries of the overwintered females were first observed at the 1st half of May. Two peaks of occurrence, from early August to mid September and from mid October to mid November, were shown at soybean field that was sowed on May 24. The two peaks almost corresponded to those of the 2nd and 3rd generations at the university campus, respectively.
