Photocatalyzed degradation of acetylene, propylene, and propane gases were carried out over precoated titanium dioxide(anatase) illuminated UV light in a flow reactor. photocatalytic oxidation of acetylene, propylene, and propane gases respectively indicated high conversion rates (78.0%) to CO₂gas. And photocatalytic oxidation of three gases according to a fold, twofold, and threefold of titanium dioxide(anatase) respectively gave high conversion rate. The longer reaction time was, the higher conversion rate to CO₂gas showed.

뽕잎은 본초강목과 동의보감에 소갈증, 뇌졸중등에 효과가 있다고 기록되어 있으며 최근의 과학적인 연구결과서도 중국의 전통생약으로 당뇨병을 예방, 치료하며 잎에는 flavones, steroids, triterepenes, 다량무기질 성분이 함유되어 있다.이외에도 여러 생리활성에 대한 연구가 밝혀지고 있으며 다방면에서의 이용가능성과 기능부여에 대한 기능성소재로서의 이용가치가 높은 것으로 사료되나 아직 식생활에 응용되는 실질적인 연구가 매우 미비한 상태이다.따라서 본 연구에서는 혈압조절에 효과가 있는 다량무기질(칼슘, 칼륨, 마그네슘)함량이 풍부한 다식을 제조하고자 뽕잎분말을 여러비율(0∼4%)로 첨가하여 관능평가, 일반성분 및 무기질함량 등을 분석한 결과 뽕잎분말을 2%첨가한 다식의 관능평가가 가장 우수하였으며 일반성분과 무기질함량은 뽕잎의 첨가비율이 높을수록 유의적으로 증가되었다.

To study the residue of organophosphorus pesticides in the ocean environment on the Cheju island, azodrin [Dimethyl - 1 - methyl - 2 - methyl carbamoylvinyl phosphate] and EPN [O - ethyl - O - 4 - nitrophenyl Phenyl phosphonothioate] of organophosphorus pesticides are surveyed on coastal environment of the Seogiupo in Aug. 1996 The numbers of theoretical plate(N) for azodrin and EPN on the GC-FPD are 72 and 866, respectively. The plate height(H) is 34.44 of azodrin, 5.35 of EPN. The detection limit of azodrin and EPN is 0.57pg and 0.64pg by GC-FPD, respectively. The qualified limit detection is 0.012ng/mL of azodrin and 0.010ng/mL of EPN in the water by GC-FPD. The qualified limit detection of Azodrin and EPN are 0.020ng/g and 0.024ng/g of EPN in the Ecklonia cave, respectively Azodrin and EPN are not detected in seawater and Ecklonia cave, Azodrin and EPN used in the farm on the Cheju island are not residued in the coastal environment.

〈Objective〉 This study were carried out to study to assess the relationship between job characteristics, general characteristics, health behaviors, and psychosocial distress and suggested the preventive oriental medicine approaches in occupational health area. 〈Methods〉 We measured job characteristics(job demand, job control, jop insecurity) by The Karasek's Job Content Questionnaire, health behaviors(smoking, drinking, exercise, coffee), general characteristics at work by a self-administered questionnaire. Psycho social distress was measured by PWI(Psychosocial Well-being Index), a 18-item self- administered instrument. 370 data for research were collected through the process of oriental health examination with questionnaire in workplace. Statistical analysis was done by t test, oneway ANOVA, and hierarchical multiple regression analysis with SPSSWIN (version 10.0) 〈Results〉 Among the 152 respondents, the prevalence of high job strain was 27%(41 persons). The Odds ratio of high job strain was 3.11(95 2.12~4.11), and those of passive group and active group were 2.01(95 0.83~2.76) and 1.80(95 0.83~2.76), respectively. Our results supported the association between psychosocial distress and job strain. 〈Conclusion〉 The odds ratio of high strain isolated group(high strain group+low social support) was 3.59(95 2.05 5.13), but the odds ratio of high strain collective group was 1.32(95 0.23 2.41). Social support at work was modifing factor of the association between psycho social distress and job strain. Therefore we reviewed the evidence that economic depression was associated with psycho social distress in this study, and that the strength of the social support was important in maintain health.

중소기업유형에 따른 인적자원시스템과 조직성과에 관한 연구 : The Case of Medium and Small Sized Firms

김정덕,조영호 한국중소기업학회 2002 中小企業硏究 Vol.24 No.4

본 연구는 한국 중소기업에 있어서, 인적자원시스템이 성과에 미치는 영향을 검증 하였다. 이를 위하여, 인적자원시스템과 중소기업을 네 개의 유형으로 각각 구분 하였다. 그리고 인적자원시스템의 특성과 유형의 두 차원에서, 전략적 인적자원관리의 세 접근방법-보편적접근, 상황적 접근, 형태적 접근-에 따라 가설을 설정하고 검증 하였다. 205개 표본 중소기업에 대한 연구결과, 인적자원시스템 특성(투자개념, 시장논리)은 성과와 정적으로 관련되었고, 중소기업 특성(기술력, 의존도)가운데 의존도는 이 둘의 관계를 부분적으로 조절하였다. 또한 네 가지 인적자원유형들간에 유의한 성과 차이가 나타난 반면, 인적자원유형과 중소기업유형간의 상호작용효과는 나타나지 않았다. 따라서, 보편적 정근이 강하게 지지된 반면, 상황적 접근과 형태적 접근은 부분적으로 지지되었다. 한편, 중소기업 가운데, 세 유형의 기업이 각각 다른 인적자원유형과 연결 되었는데, 기술력이 낮은 두 유형의 기업은, 최선의 인적자원유형을 적용하지 못하고 있었다. 따라서 이들 기업에 적합한 인적자원유형을 제안하였다. This study examines the impact of human resource(HR) systems on corporate performance among medium and small sized firms in Korea. For this purpose, we classified HR systems and firms into four different types, And develope several hypotheses based on three approaches to strategic human resource management universal, contingency and configuration approaches. The universal approach predicts a positive relationship between performance and HR systems. The contingency approach predicts that characteristics of firms will moderate the relationship between performance and HR systems, Finally, the configuration approach predicts that there will be an ideal HR type, and relationship between HR types and performance will be contingent on a firm type. The authors tested the hypotheses with the sample of 205 medium and small sized companies. The results support the universal approach. The contingency and configuration approaches receive partial support. Addtional analysis showed that three of four firm types actually linked with different HR system types. We discussed the implications of these findings in more detail.

모반세포성 모반과 악성 흑색종의 CD44 발현에 관한 면역조직화학적 연구

CD44 is the major human cell surface receptor for hyaluronate and mediate cellmatrix and cell-cell interactions involved in the mechanisms of tumor invasion and metastasis. Typical acquired melanocytic nevi appear to follow a life cycle characterized by active growth, maturation, and progressive involution, In contrast, congenital melanocytic nevi have a different course and prognosis with potential for development of melanoma, and metastatic spread is very common in malignant melanoma. We investigated the expression of CD44 in acquired and congenital melanocytic nevi, and malignant melanoma by immunohistochemical technique. Formalin-fixed and paraffin-embeded tissue from 5 compound nevi, 6 intradermal nevi, 5 congenital melanocytic nevi, and 5 malignant melanoma were immunolabeled with monoclonal antibodies directed against CD44. All acquired melanocytic nevi showed negative or weak staining for CD44. However, all congenital melanocytic nevi exhibited positive staining for CD44 with minimal irregularities according to location. In malignant melanoma, there was variable intensity of staining for CD44 in different areas of the tumor. These findings suggest that the different expression of CD44 in melanocytic nevi may contribute to different biological behavior between acquired and congenital meanocytic nevi. and CD44 seems to be related to metastasis and tumorigenesis of the malignant melanoma.
