This paper reports on findings from empirical studies of small group activities in a Japanese company and a Korean company. The researches were practiced with the same method which Rao et al. (1987) did on autonomous work groups in U.S.A. This study attempts to explain the differences in job satisfaction between high productive and low productive small work groups in each country and compare three countries' situations. According to the result, high productive groups indicated higher degree of job satisfaction than low productive groups. In the case of U.S.A., results show the importance of establishing and communicating a policy of promotional opportunities to reward high performance, and selecting and training leaders on important leadership dimensions. In the case of Japan, it is important to activate QC circle activity, and to encourage good human relations and member's cooperation and unity. In the case of Korea, besides activating QC circle activity, it is also necessary to equalize the difficulty of the works, or to set up the p ay system taken the difficulty of the works into consideration

소프트웨어 신뢰도 성장 모델을 기반으로 한 정량적 품질 평가법

윤정모 서울産業大學校 1994 논문집 Vol.40 No.1

Software reliability assessment is very important in developing a quality software product effciently. This paper discusses the quantitative measurement and assessment of software reliability. The techniques are based on the software reliability growth models(SRGM's) developed in Korea, which are characterized by nonhomogeneous Poisson processes. A summary of existing SRGM's is given, and the maximum-likelihood estimations based on the SRGM's are discussed for software reliability assessment. Thought the use of a software reliability assessment tool that incorporates several leading SRGM's examples of software reliability assessment are given for some sets of observed test data taken actual software projects.

Purpose: The change of the marginal bone around dental implants have significance not only for the functional maintenance but also for the esthetic success of the implant. The purpose of this study was to investigate the load transfer of internal conical joint type implant according to marginal bone resorption by using the three-dimensional finite element analysis model. Materials and methods: The internal conical joint type system was selected as an experimental model. Finite element models of bone/implant/prosthesis complex were constructed. A load of 300 N was applied vertically beside 3 mm of implant axis. Results: The pattern of stress distribution according to marginal bone resorption was similar. The maximum equivalent stress of implant was increase according to marginal bone resorption and the largest maximum equivalent stress was shown at model of 1 mm marginal bone resorption. Although marginal bone loss more than 1mm was occurred increasing of stress, the width of the stress increase was decreasing. Conclusion: According to these results, the exposure of thin neck portion of internal conical joint type implant is most important factor in stress increasing. 연구 목적: 지금까지 성공적인 임플란트 치료를 위해 많은 연구가 진행되어 왔으며, 임플란트 주변 골 흡수 현상에 대한 연구는 매우 관심이 높은 분야 중 하나이다. 이에 본 연구에서는 삼차원 유한요소응력분석을 이용하여 변연골 흡수가 내측연결 임플란트 매식체의 기계적 안정성에 미치는 영향을 간접적으로 확인하고자 하였다. 연구 재료 및 방법: 악골에 식립된 내측연결 형태의 임플란트 매식체에 티타늄 소재의 임플란트 지대주를 지대주 나사로 연결하고 상부에 금합금관을 장착하는 삼차원 유한요소모형을 설계하였다. 0, 1, 2, 3 mm의 변연골 흡수 상태를 적용하고, 교합면 중심에서부터 3 mm 편측에 300 N의 수직 하중을 가하여 임플란트 매식체에 발생하는 최대 주응력을 계산하였다. 결과: 유한요소분석결과 변연골 흡수에 따른 임플란트 매식체의 최대 주응력 분포는 유사한 양상을 보였으며, 임플란트 매식체 상단에서 가장 높은 응력 집중이 나타났다. 최대 주응력은 처음 1 mm 변연골 흡수를 가정하였을 때 가장 크게 증가하였고, 이후 변연골 흡수가 증가할수록 응력은 증가하였지만 응력 증가의 폭은 감소하는 경향을 보였다. 결론: 이러한 결과로부터 내측연결 임플란트에서 매식체 두께가 얇은 경부의 노출은 변연골 흡수로 인한 응력 증가에 가장 큰 원인임을 알 수 있었으며, 매식체의 변형, 균열 및 파절 등의 기계적 실패를 감소시키기 위해서는 이에 대한 외과적, 보철적 고려가 필요할 것으로 생각된다.

Developement of dance acadamy has not be developed much, content, object and territory of dance academy are not clear as well. Under these circumstances, we need much effort of studys, and need to study of dance in whole territory for developement of dance academy. Especially, theoretical stands of sociology of dance is need immediately under the present society. Social roll and function of dance, and dance roll and function of society are already recognized. These points are dealt in folklore. These phenomena are due to that there were not studies about unique dance studies, and not only qualities of studies but also qualities of studies are not much comparing to other academies. Lately, some of these about dance are published, and dance theorists are growing. In this time, We need to arrange dance field and to take a triangular position in the sociology of dance as a stimulant, confrontation. As more, sociology of dance is required to take a triangular position as one field of sociology to corver all the social area, as soon as revising to pursue only a aesthetical value of dance. So, next are Meannings and assignments of the sociology of dance according needs of sociology needs of sociology of dance standing. Meannings of the sociology of dance standing 1) It will make develope Dance acadamy, and stimulate the groping of the systematic domain of dance. 2) It will popularization of dance, because it can make clear the phase of position of dance in the practical side rather than ideal side. 3) It will easily make sociology of dance to take part in similar study, like dance aesthetics, dance philosophy and art theory. 4) General, objective and scientific criticism will be possible in criticicizing dance, because it adds not only aesethetic objection but also social side. 5) Choreographers can be interested in social problems, because sociology of dance is getting important, therefore deep creation can be achieved. 6) The populace's response can be high after PHASE 5), the recognition about dance can meet new aspects. 7) Rather serious and systematic studies can be proceeded, through considering dance in relation to society. 8) It will offer a chance to sociology of dance to take important position in a curriculum of dance academy. 9) It is very helpful to similar studies, because studies of sociology of dance are related to general studies of all field of society. 10) More social scientific experimentation studies will be developed, which is differed from present comprehensive studies. 11) It will present our dance socioty' direction, moving formore, our socioty'direction also. Assignments of the sociology of dance standing 1) The exact sociology of dance standing should be set up after discussing specific and purpose of dance. 2) Reserching content should be chosen after arrangement of dance conception and selection of research object. 3) Research territory has to be discussed by arrangement of research content. 4) Adaptable research method for sociology of dance has to be studied. 5) It should be studied about thoretical background of sociology of dance and boundary and theory application of sociology. 6) The people studing sociology of dance should be multitudinous. 7) The meeting and institude studying sociology of dance are acutely required and lots of qualitive and quantive research are needful.

간질성 신염은 신장의 간질을 선택적으로 침범하는 염증성 질환으로 여러가지 원인에 의해 유발되며, 이 중 약물에 의한 경우는 각종 항생제, 비스테로이드성 진통제, 항경련제, 이뇨제, 면역억제제등에 의한 증례들이 보고되고 있다. 현재 각종 질환-특히 만성질환-의 치료에서 한약이 차지하는 비중이 적지 않으나, 그 각각의 성분들이 유발할 수 있는 부작용들에 대한 연구는 거의 없는 실정이다. 저자들은 관절염 치료를 위해 중국산 한약을 복용한 후 복통, 피로감 및 육안적 혈뇨를 주소로 내원한 두 환자에서, 단백뇨와 신기능 장애를 보여 시행한 신조직 생검상 급성 간질성 신염에 합당한 병리학적 소견을 보이고, 한약 복용 중지 후 급속한 회복을 보여, 한약에 의해 유발된 것으로 사료되는 급성 간질성 신염 2예를 경험하였기에 문헌고찰과 함께 보고하는 바이다. Acute interstitial nephritis is a disease characterized by renal interstitial inflammatory cell infiltration and acute renal functional deterioration. This is caused mainly by antibiotics, NSAID and diuretics such as thiazide, but cases induced by herb medication are rare. We experienced two cases of acute interstitial nephritis after treatment with herb medication. One 71-year-old female patient and the other 60-year-old female were admitted to the hospital because of general weakness and gross hematuria. Microscopic hematuria, pyuria, and proteinuria were presented. After definitive diagnosis with a renal biopsy, we noted rapid recovery of renal function by drug withdrawal and steroid therapy. We report these cases with a review of the referenced literatures. Key Words : Herb medication, Acute Interstitial nephritis.
