  • This study proposes strategies for information requirements analysis (IRA) for successful agricultural management information system (MIS) development. The study frist defines IRA based on literature review and emphasizes the importance of IRA by its position in SDLC (System Developments Life Cycle). Then, the study reviews fifteen cases of agricultural MIS development projects appeared in the report of all the MIS related ARPC(Agricultural R&D Promotion Center) projects from 1995 to 1998 and finds that IRA is not properly performed in most of the projects. Finally, this study proposes seven strategies for IRA for successful agricultural MIS development based on the finding of this study and those from the literature related to IRA methods.

  • Starter cultures were developed for the extension of the shelf life of bread. Lactobacillus plantarum and Bifidoacterium longum were selected as the mixed culture with Propionibacterium freudenreichii. P. fredenreichii with B. longum and L. plantarum produced 2.261% and 1.715% total acid, and pH value of cultured solutions was near 3.95. Propionic acid was produced 14 ~16 mg/ml by P. freudenreichii with L. plantarum and B. longum during 17 days, which was more than that of L. brevis. The pH values of the bread were 4.83 and 4.89 in respect to B. longum and L. plantarum when the fermented products were used to make the bread. Mold was not found for 10 days of storage of the bread at room temperature when the fermented products of B. longum were used for making bread. 37$^{\circ}C$, pH 6.0 and the lowest agitation were optimum conditions for the production of propionic acid in the scaled up fermentation.

  • Self-esteem and social supports are important variable influencing adjustment to college life. The study aims to identify the factors influencing college students' adjustment moderating effects on social supports. Data were collected from 265 usable questionnaires among college students in Pyeongtek University. Results of a factor analysis yielded three dimensions of self-esteem which were talent/attitude and capacity/pride. And results of factor analysis also yielded three dimensions of social supports which were family, friends, and professor supports. Hierarchical regression analysis revealed that capacity/pride and all of social support factors affected significantly for adjustment to college life. And female and attitude for students' major had a positive affect on adjustment to college life. It was suggested that self-esteem, social supports, and aptitude for students' major should be considered in college management policy.

  • This study represents the newly advanced formulation of hydraulic fluids for extended drain interval and introduces the performance results of used oil samples from various excavators. The used oil samples, in this paper, show that there is a sharp change in viscosity drop and moderate additive depletion when viscosity index of hydraulic oil is very high. For the extension of hydraulic fluid life, it is necessary to improve the stability of viscosity and oxidation. New target properties from the used oil analysis were proposed for extended life. Performance of newly developed hydraulic oil based on used oil analysis is compared with previously used one. The properties of new formulation are the viscosity index of 140 and improved thermal stability consists of VHVI base oil. Field test results showed the possibility of extension of fluid life. Additionally, for development of high performance product, new required propertied and performances were discussed.

  • This study aimed to investigate couple relationship and related variables of women immigrants. Especially, the study focused on curve term between couple relationship and related variables. The data were collected from a sample of 346 women immigrants living in S city, Chungnam province. First, the study indicated that there was some curve relationship between couple satisfaction and period of residence in Korea. Namely, the couple satisfaction of women immigrants was likely to decrease at the early period of residence, but the longer the period of residence was, the higher the couple satisfaction was. Second, the result revealed that there was no significant relationship between couple satisfaction and level of Korean proficiency. Third, there was some curve relationship between couple satisfaction and satisfaction of life. The couple satisfaction was likely to increase in a shape of curve according to the increase of life satisfaction.

  • The rapid deterioration of fermented rice-wine, called Tak Joo and Yak Joo, is one of the serious problems for brewing and marketing in Korea. In this study the biochemical and microbiological investigations have been performed for extension of shelf-life of the rice-wine by the method of combined heat and radiopasteurization. Major microflora in this wine is proved as Saccharomyces cereoisiar, which is destroyed by h-at treatmznt ($70^{\circ}C$, 10 min.) combined with gamma-irradiation of 240 K, rads doses. The changes of chemical constituents of them were investigated during the storage period at room temperatures of summer days($33^{\circ}C$). The results of sensory test for gamma-irradiated rice-wine with lower doses show no significant unfavourable off-odor nor color change compared with the fresh rice-wine. Therefore, it is revealed that the combined process makes possible extension of shelf-life of fermented rice-wine in markets without any deterioration and loose of its particular tastes at least for three weeks.

  • Background: Lateral epicondylitis (LE) is the most common chronic musculoskeletal conditions of the upper extremity with pain and wrist extension disability. The tendon which is most affected is the extensor carpi radialis brevis (ECRB). Previous study evaluated the effect of taping technique on patient with LE, but no study investigated the changes of electromyography (EMG) on ECRB when using dynamic taping (DT) technique. Objects: The aim of this study was to investigate the effect of DT technique using dynamic tape on muscle activity of ECRB during wrist isometric extension, isotonic extension and flexion. Methods: Twenty-one healthy subjects volunteered to participate in this study. Subjects were instructed to perform wrist isometric extension, isotonic extension and flexion without and with DT on origin area of ECRB. Wrist isometric extension was performed at 75%, 50% and 25% (%maximal voluntary contraction force), respectively, based on maximum contraction force. Isotonic extension and flexion test used dumbbell. EMG data was collected from ECRB. Results: EMG of ECRB were statistically significant decrease in wrist isotonic extension after DT (p < 0.05). Significant increase in wrist isometric extension during 25% and 50% force task (p < 0.05). Conclusion: This study applied DT technique to suppress the wrist extensor muscles in 21 healthy adults in their twenties. Change in muscle activity was compared in the ECRB muscle during wrist isometric extension, isotonic extension and flexion task. Based on the results of this study, the DT technique applied to the wrist and forearm area can reduce the load on the wrist extensors when the wrist performs various movements during daily life movements or repetitive tasks, and by using these effects, excessive stress is applied to tennis elbow patients.
