This study conducts the questionnaire of satisfaction of girls'students at four girls' middle schools in Gwang-ju on their achool uniform and obtains the following results.First, it is shown that their satisfaction of the current school uniform design is low and its major reason is that they don't like its design. So the design considering the aesthetic sense of school uniform should be developed. Second, it is found that they show low satisfaction on the colors of their school uniform, prefer white blouse and vest gray skirt and blue winter jacket. Third, they have high dissatisfaction in the upper and lower length of school uniforms and they prefer the length of coat inder waist and the length of skirt 3㎝ below the knee most. Fourth, in the survey of preference of materials, they prefer cotton most and the use of materials complementing the functionality of school uniform material is required. From the above results, school uniform designs students prefer are as follows; They prefer sailor collar blouse and pleat skirt most which can consider refersh and beauty for summer school uniform. As spring-and-atumn school uniform, they prefer shirt collar, thght sleeve and semi-tight skirt most. As winter school uniform, they like standing collar which considers coldness and function. This study is conducted with four schools at specific area, but it suggests the following researches which consider the diversification of schools.

The laboratory quench method used in this study is based on plunging a silver cylinder heated to 800±1℃ into mineral base oils at given temperature. Experimental apparatus and measuring method followed the Korean Industrial Standard. Cooling curves at the boundary of the shape of cylinderical type measured by a silver-alumel thermocouple is recorded throughout the quenching period. Using the cooling curves, the collingability of the quenching oils at a various temperrature were compared and discussed.

The gamma irradiation effect of dried fernbraken was investigated on the physical and sensory qualities during and after soaking process. Dried fernbraken packaged in vacuum was irradiated up to 7 kGy with γ-ray produced by 132 Cs at 0℃. Moisture content and rehydration rate of gamma-irradiated fernbraken after soaking increased significantly depending on the irradiation doses(p<0.05). Lightness(L), redness(a) and yellowness(b) values of Hunter color system increased significantly in the gamma-irradiated fernbraken after soaking, compared with control, while the hardness and chewiness by the texture analyser decreased significantly in irradiated ones. Sensory evaluation results showed that the mean scores of flavor, appearance, taste, texture and over-all acceptability in soaked fernbraken irradiated were not significantly different from those in control, except higher preference score of texture in irradiated ones. From these results, it might be concluded that the irradiation does not affect the physical and sensory qualities of dried fembraken during and after soaking, especially in texture.

7β[5-(Substituted) phenyl-2H-tetrazol-2-yl]acetamidocephalospranic acid, 7β-(5-Diphnenyl-methyl-2H-tetrazol-2-yl) acetamidocephalosporanic acid and 7β-[5-(Substituted)-4-phenyl-1.2.4-triazol2-yl]thioacetamidocephalosporanic acid were synthesized and tested in vitro antimicrobial activity. These compounds exhibited good antimicrobial activity against Gram-positive bacteria whereas most compounds showed decreased antimicrobial activity against Gram-negative bacteria

사회복지조직의 실제채용기준을 반영할 수 있는 채용공고에 대한 탐색적 연구 : 서울·대전지역을 중심으로

본 연구의 목적은 사회복지조직의 공개 채용공고가 실제채용기준을 얼마나 반영하고 있는지 파악하여 채용공고의 변화가능성을 탐색하기 위함이다. 이러한 목적을 달성하기 위해 2008년 한국사회복지사협회의 채용공고 중 210건의 조직을 표집하여 기초분석을 통해 정보내용을 파악하였고, 서울과 대전의 23개 조직의 기관장을 대상으로 1:1면접을 통해 사례연구를 진행하였다. 분석결과, 실제채용기준은 자원봉사와 실습을 통한 현장경험, 사회복지사 1급 자격증, 지원자와 조직의 비전 일치, 사회복지 마인드, 대인관계 등으로 드러났다. 그러나 이는 채용공고에 제시되지 않거나 질적인 차이를 보였다. The purpose of this study is to understand how an open employment notice has reflected the actual criterions of the recruitment, and to discover a potential for any changes. To achieve this purpose, a systematic random sample of 210 open employment notices was selected from Korea Association of Social Workers in 2008, and a descriptive analysis was conducted. The qualitative research was carried out for the case study with 23 interviewees from social welfare organizations in Seoul and Daejeon. Consequently, the actual criterions of the recruitment included the following elements: social work field practicum and volunteer work, the level one social welfare license, degree of harmony with the vision of the organization, dept of social welfare-oriented mind, and human networks. However, these criterions may not be presented in open employment notices or show that there are qualitative differences between open employment notices and the actual employment criterions.

Most persons who become infected with M. tuberculosis mount a protective immune response and remain clinically well, the only evidence of infection being development of a positive tuberculin skin test. Five to 10% develop tuberculosis disease within the first 2 years after infection (primary tuberculosis) or thereafter (reactivation tuberculosis). Acquired resistance against tuberculosis paradigmatically rests on cell-mediated immunity, with the major factors being mononuclear phagocytes and T Lymphocytes. While the former cells act as the principal effectors, the latter ones serve as the predominant inducers of protection. The usefulness of the single dose of BCG routinely given in childhood in many developing countries in preventing far more commonly occurring tuberculosis in adults is in doubt. An effective and safe vaccine against tuberculosis is sorely needed. A subunit vaccine are capable of inducing protective immunity and could have substantial advantages over BCG or other whole-bacterium vaccines. The human promyelocytic cell line HL-60 adopted characteristic macrophage-like properties, including adherence and CD14 expression after a period of continuous culture at high ambient CO_(2) concentration. When HL-60 cells were cultured with 1,25-dihydroxyvitamin D_(3) for 4 days, the cells acquired the activity to potentiate T cell proliferation by the 30 kDa or 38 kDa antigen of Mycobacterium tuberculosis H37Rv Therefore, vitamin D-treated HL-60 cells showed the function of the antigen presenting cells.
