      • On the Best Linear Estimator of Mean Life

        Yeum, Joon Keun 동국대학교 재료과학연구소 1982 材料科學硏究所 論文集 Vol.2 No.-

        Failure Censored 표본으로부터 平均壽命에 대한 最良線型 推定量에 대하여 살펴봄. Let X_1≤X_2≤…≤X_r denote the r smallest ordered observations from a set of n independent observations on the exponential distribution. Then we can obtain the U.M.V.U.E of θ. However it is not the best linear estimator of θ.

        PARTNERSHIP, PARTICIPATION AND PARTITION IN URBAN DEVELOPMENT POLITICS IN KITAKYUSHU, JAPAN

        Yeum, Mi-Gyeung 경남대학교 극동문제연구소 2002 ASIAN PERSPECTIVE Vol.26 No.2

        This article examines the characteristics of the governing structure over two time periods in the Japanese industrial city of Kitakyushu through the use of urban regime theory. Kitakyushu is known as a corporate city or castle town for industries related to steel. Kitakyushu's growth management politics started to form with environmental issues in the early part of the 1960s. Public private partnerships for environmental management were constructed, and environmental management was done by an alliance of the city government and business. In the late 1980's, in period of urban decline and restructuring, the existing form of exclusive partnership between local government and large companies began to extend to a new form that included various community levels and interest groups. But the incorporation of community interests into the urban decision-making process in Kitakyushu has limitations. It is more concerned about the realization of company profits than community interests. Decision-making power thus is still concentrated in local government and large corporations within partnership structures.

      • Optimal Software Release Policies with Imperfect Debugging

        Yeum,Joon-Keun,Kim,Hee-Soo 동국대학교 자연과학 연구원 1999 자연과학연구 논문집 Vol.4 No.-

        This paper considers a software release policies for a software cost model with imperfect debugging by assuming that new faults are sometimes introduced when the faults originally latent in a software system are corrected and removed during the testing phase and operating phase. A software reliability model based on the NHPP is used. The optimal release polices to minimize the expected total software cost are discussed. Finally, numerical examples are shown to illustrate the results of the optimal polices.

        A Case of Basal Cell Carcinoma Arising in Linear Porokeratosis

        Yeum, Jung Sub,Suh, Jin Chun,Shin, Dong Ju 대한피부과학회 2003 Annals of Dermatology Vol.15 No.2

        Porokeratosis are characterized by distinct clinical findings of a keratotic ridge that corresponds to the cornoid lamella on histology and has well defined potential for malignancy. We report a case of basal cell carcinoma(BCC) arising in linear porokeratosis in a 77-year-old man.

        A Study on Relations between Corporate Citizenship, Corporate Reputation and Job Pursuit Intention

        YEUM, Ahyoung(염아영),Han, Eunkyoung(한은경) 한국광고홍보학회 2014 한국광고홍보학보 Vol.16 No.4

        본 연구는 기업의 시민정신과 평판이 구직자들의 구직의도 간의 영향을 살펴보았다. 기업 역시 사회를 구성하는 시민의 일원으로서 좋은 구성원이 되기 위해 행하는 일련의 노력들이 기업의 가장 중요한 무형자산 중 하나인 기업의 평판을 형성할 것이라고 보았다. 나아가 이렇게 형성된 긍정적인 기업시민정신과 평판을 구직자들이 기업에 대한 속성과 근무환경을 평가하는 단서로 사용할 것으로 예측하여, 특정 기업에 대한 구직의도를 형성하는데 영향을 미칠 것이라고 가정하였다. 구직의도가 형성되는 과정을 자세하게 살펴보기 위해 본 연구는 합리적행동이론을 연구모형에 적용하였다. 합리적행동이론의 두 가지 변인, 행위에 대한 태도와 주관적 규범을 매개변인으로 포함하였다. 연구결과 모든 차원의 시민정신과 구직자들의 구직의도 간에 직접적인 관계는 없는 것으로 나타났다. 하지만 기업시민정신은 기업의 평판을 평가하는데 있어서는 긍정적인 영향력을 미쳤다. 매개변인의 검증결과, 기업평판의 매개효과는 유의하게 나타나지 않았지만, 합리적 행동이론의 변인들은 기업시민정신과 구직의도 간의 관계를 매개하는 것으로 나타났다. The present study investigated the effects of perceived corporate citizenship and corporate reputation on job seekers’ pursuit intension. This study anticipated that the corporate efforts to be a good citizen would develope the corporate reputation assets, which is one of the most important intangible assets. And this positively perceived corporate citizenship and reputation were expected to be influential in improving positive intention about the organization because job seekers would use corporate citizenship and reputation as a signal to predict organization’s attributes or working environment. Moreover, in order to understand job seeker’s decision making process more in detail, this study applied the theory of reasoned action to the research model. Two variables of the theory such as attitude toward getting a job and subjective norm were examined as mediators. This study found that all dimensions of corporate citizenship had no direct effect on job seeker’s pursuit intention. However, corporate citizenship had positive effects on corporate reputation. In terms of meditating role of the relationship between corporate citizenship and job pursuit intention, corporate reputation failed to verify, but two variables of the theory of reasoned action completely meditated the relationship. It provided substantial support of the theory of reasoned action.

      • 고환종양의 태반생성물질 분포에 관한 면역조직화학적 연구

        염석호,염범우,최종상 고려대학교 의과대학 1988 고려대 의대 잡지 Vol.25 No.1

        There were many efforts to find out specific tumor markers of variable tumors for the purpose of early cancer diagnosis, evaluation of cancer treatment and early detection of cancer recurrence. Now many placental hormones and proteins are believed to be produced by tumors of various origins. Among these, PAP, SPI, PAPP-A, HCS and β-HCG are included. Testicular tumors, especially in nonseminomatous germ cell tumors, are known to produce several placental products such as AFP and HCG. But there is no report specific for tumor marker of seminoma. Therefore, the author tried to evaluate presence of above 5 kinds of placental products in the tissue of testicular seminoma, teratoma, choriocarcinoma, embryonal carcinoma, yolk sac tumor, embryonal rhabdomyosarcoma and malignant lymphomaby ABC method, of immunoperoxidase stain, The results are followings: 1. All 5 cases of seminoma revealed strong positive reaction along the cell membrane to anti-PAP antisera. 2. Syncytiotrophoblast of choriocarcinoma and glandular epithelial cell in teratoma showed positive reaction to anti-SPI antisera. 3. Both seminoma and choriocarcinoma, and even embryonal rhabdomyosarcoma and malignant lymphoma disclosed positive reaction to anti-PAPP-A antisera.

      • On the Efficiency for Ridge Estimator

        Yeum, Joon Keun 동국대학교 재료과학연구소 1982 材料科學硏究所 論文集 Vol.2 No.-

        偏倚推定量인 Ridge Estimator를 一般化 分散이라는 基準에서 最小自乘推定量과 비교함. Much attention has been paid to the bias of coefficients resulting from ridge regression. Looking at bias alone implies that ridge estimators are inferior. However, using the criterion of the generalized variance, ridge estimators are better than ordinary least square estimators.
