The purpose of this study were to segment the hair care cosmetics market according to the benefits sought, to categorize the information sources on the hair care cosmetics, and to characterize the profiles of the segmentized groups of university students. Self-administered questionnaires were distributed to 457 university students in Chonbuk province from Jul. 10 to Jul. 21, 1999. Frequencies and percentages were calculated, and factor analysis, cluster analysis, one-way ANOVA, and $\chi$$^2$-test were used. The results were: 1. University student's benefit variables on hair care cosmetics were classified into special function, fashion, practicality, brand, fragrance, styling, nutritional reinforcement, and economy. And they were segmentized into the feeling pursuit, the multi-benefit pursuit, the practicality pursuit, the benefit unconscious, and the function pursuit. The information sources were classified into marketer-dominated sources, neutral sources and consumer -dominated sources. 2. The feeling pursuit strongly sought for fashion, brand and fragrance pursuit, but considered economy less, chiefly used the marketer-dominated and neutral information sources, and showed much interests in hair care cosmetics, and were consisted of women dominantly. The multi-benefits pursuit sought for various kinds of benefits from hair care cosmetics, depended heavily on various kinds of information sources, were well aware of their hair types and instructions on the hair care cosmetics label, and were consisted of women dominantly. The practicality pursuit highly sought for practicality, but low on the fashion, were not aware of their hair style, haler care, hair health status and hair type, and almost half of them are men. The benefit unconscious showed low concern about, all kinds of benefits and hair care cosmetics, and were consisted of more men than women. The function pursuit highly sought for special function and nutritional reinforcement, mainly depended on the consumer-dominated sources. and showed low concern about their hair style and hair care.

Objectives: This study was carried out to know the effects of Gwan-Jul-Bang-7 (hereafter referred to GJB-7) on the inhibition of arthritis induced by collagen on the mouse. Methods: To assess the effects of GJB-7 on mouse with arthritis induced by collagen II, we conducted several experiments such as analysis of cytotoxicity, hepatotoxicity, arthritis index, total cell number of draining lymph nodes and paw joints, value of immunocyte in PBMC (peripheral blood mononuclear cell), DLN (draining lymph node) and paw joint, measurement of cytokine and anti-collagen II, observation of the histological changes of joint. Results: 1. Cytotoxicity against HFC (human fibroblast cells) was not observed in any concentration and hepatotoxicity was not observed in the GJB-7 treated group. 2. The incidence of arthritis significantly decreased. 3. Total cell number of draining lymph nodes significantly increased and total cell number of paw joints significantly decreased. 4. The percentage of $CD8^+$ cells in PBMC (peripheral blood mononuclear cell) significantly increased. The percentage of $CD3^+/CD69^+$, and $CD3^+/CD49b^+$ cells in PBMC significantly decreased. 5. The percentage of $CD19^+,\;CD3^+$, and $CD4^+/CD25^+$ cells in DLN (draining lymph nodes) significantly increased. The percentage of $B220^+/CD23^+$ cells in DLN significantly decreased. 6. The percentage of $CD3^+,\;CD4^+$, and $CD11b^+/Gr-1^+$ cells in paw joints significantly decreased. 7. The production of TNF-$\alpha$, IL-6, and MCP-1 significantly decreased. 8. Anti-collagen II in serum significantly decreased. 9. With the hematoxylin and eosin stain, inflammation of joint decreased. Under Masson's trichrome stain, the cartilage destruction and synovial cell proliferation and the expression of collagen fibers decreased. Conclusions: Comparison of the results for this study showed that GJB-7 had immunomodulatory effects. So we expect that GJB-7 could be used as an effective drug for not only rheumatoid arthritis but also another auto-immune diseases.

According to the statistics publication of KOSHA, more than half of serious accidents at the construction sites were related to the temporary works and/or the temporary structures such as scaffoldings, shores, earth retaining walls, etc. The structural failures are occurred because of the overload acting on the structures or lack of performance of the one or more members of the structures. For the prevention of the collapse accidents relating to the temporary structures at the construction sites, we have to control construction processes not to occur the overload and also to control the performance and quality of each member of the temporary structures. MOLIT has amended the "Construction Technology Promotion Act" on Jan. 7th, 2015 to ensure the structural safety of the temporary structures. According to the Act, the designers of the construction design projects should check the structural integrity of the structures including the temporary structures and the construction companies have to let 'the Relative Professionals' confirm the structural integrity of temporary structures, the shores(${\geq}5m$ high) and the scaffolds(${\geq}31m$ high), before construction. Also, MOLIT has amended the "Regulation for Construction Technology Promotion Act" on Jul. 4th, 2016 for quality management and testing of temporary equipments. According th this regulation, the construction companies and supervisors should manage and test the temporary equipments before using them. In this paper, the standard drawings of the shores(< 5 m high) and the scaffolds(< 31 m high) and the amended "Business Guideline for Quality Management of Construction Work" are presented. As the result of this study, MOLIT noticed the amended "Business Guideline for Quality Management of Construction Work" on Jul. 1st, 2017.

Physicochemical environments and phytoplankton community in the nakdong river middle basin were investigated during a period of 1 year from Nov. 1993 to Oct. 1994. The ranges of Physicochemical environment factors in the nakdong river middle basin were $3.6~27.4{\circ}C$ for temperature, 7.1~9.3 for pH, $7.1~12.7mg/{\ell}$for DO, $0.7~2.1mg/{\ell}$ for BOD, $31~52mg/{\ell}$ for alkalinity, $2.101~3.3mg/{\ell}$ for T-N, $0.052~0.099mg/{\ell}$ for T-p, $5.4~92.3mg/m^{3}$ for chlorophyll-a. The number of Phytoplankton was lowest in Jan. that is, 244ce11s/ml and that was highest in Sep. 1201 cells/ml. The increase of dominant genera were correlated with the total nomber of phytoplanktons. Bacillariaceae, chlorophyceae, cyanophyceae, and euglenophlrceae were to 74.5%, 20%, 3.5%, and 2.2% respectively. Bacillariaceae were abundant during all the year round except for Jun, Jul, Aug. Chlorophyceae were plentiful in Jun, Jul, Aug. Tase-and odor-causing algae and filter clogging algae were 72% in Nov. and 93.5% in Jun. They were abundant all the year round except for winter, so they influenced on the treatment of tap water system. They belong to the general asterionella, cyclotella, melosira, nitzschia of bacillariaceae and actinastrum, pediastrum of chlorophyceae. Dominace index was low in winter and high in umber. Diversity index and equitability index were low in summer and high in winter. Therefore, the structure of phytoplankton community of the nakdong river middle basin was different form season to season.

In this study, the existence of possible deterministic longterm trend of precipitation amount, monthly maximum precipitation, rain day, the number of rain day greater than 20mm, 30mm, and 80mm was analyzed using the Mann-Kendall rank test and the data from 62 stations between 1905 and 2004 in South Korea. Results indicate that the annual and monthly rainfall amount increases and the number of rain days which have more than 80mm rainfall a day, increases. However the number of rain days decreases. Also, monthly trend analysis of precipitation amount and monthly maximum precipitation increases in Jan., May, Jun., Jul., Aug., and Sep. and they decrease in Mar., Apr., Oct., Nov., and Dec. Monthly trend of the number of rain day greater than 20mm, 30mm, and 80mm increases in Jun., Jul., Aug., and Sep. However results of Mann-Kedall test demonstrated that the ratio of stations, which have meaningful longterm trend in the significance level of 90% and 95%, is very low. It means that the random variability of the analyzed precipitation related data is much greater than their linear increment.
