In this paper, we described about the home device authentication framework, certificate issuing process and home device authentication method. since the home device authentication scheme of the public key infrastructure would be more needed as the number of home device can participate in the home network increased, we described about the home device authentication system of the public key infrastructure. Moreover, we described about the construction method of CA adminstration interface for convenient CA administration.

객체 지향 소프트웨어 개발 방법론의 하나인 통합 모델링 언어인 UML은 OMG에 의하여 표준 방법론으로 받아들였다. 본 연구팀에 개발한 UML 그래픽 편집 도구를 이용하여서 소프트웨어를 개발하는 과정에서 발생하는 설계 정보는 모델 관련 정보와 뷰에 관한 정보들을 관계형 데이터베이스에 저장 관리된다. 이들을 Web 통해서 UML 설계 정보의 관리와 공유하기 위해서 UML 설계 정보를 미리 정의한 XML DTD를 이용하여 XML 파일로 변환한 후에 웹 상에서 이를 개발자와 개발 도구들 간에 교환하여 공유할 수 있는 변환 규칙을 제안한다.

Effects of nonylphenol (NP) on gonadal development and growth of olive flounder, Paralichthys olivaceus were investigated. NP treatment was carried out to fry fish (during 55 to 64 days after hatching) using oral adminstration at nominal NP concentrations of 50, 100 and 150 tig/g BW Gonad before NP treatment was sexually undifferentiated as observed with mostly gonia cells. At 159 days after hatching, ovarian lamella of ovary were filled with oogonia and perinucleolus oocytes. On the other hand, testicular lobules of the testis were occupied by spermatogonia, spermatocytes and spermatids. Histological observation of ovary and testis development was any different between the control and NP treated groups. However, growth was significantly increased in NP treated groups than control groups (P< 0.05). These results considerate that NP has any effect for sex differentiation and gonadal development, but act for early growth in olive flounder.

Cheung-Gan-Haeju tang has been used on 3 cases of alcoholic liver disease patients complicated with ascites, clinical symptom(fatigue. jaundice, urine dark, indigestion, anorexia. ascites etc), liver function (AST, ALT, ${\gamma}$-GT, ALP, total bilirubin), and index of nutritional state (total protein, albumin, cholesterol) were improved after the adminstration. Although the exact mechanism involved in the effects of Cheung-Gan-haeju tang on these disease is still unknown, it is possibly suspected that Cheung-Gan-Haeju tang is non-toxic to liver and has beneficial effects on treating alcoholic liver disease complicated ascites. Further reports with many case, however, will be needed.

This research uses measures of transformational and transactional leadership to examine its impact on subordinate psychological empowerment and on his/her creativity in 3 resort complexes. For a total of 462 respondents, followers' sense of increased empowerment and creativity are significantly and positively related to the transformational leadership behaviors of their immediate superior, including charismatic attributes and behaviors, individual consideration, and intellectual stimulation. Two of the three transactional leadership measures, including contingent reward and management-by-exception(active), correlate positively with the followers' perceived empowerment and creativity, but the rest one, management-by-exception(passive), negatively with them. The impact of all of the three measures of transformational leadership and the two of transactional leadership(i.e., contingent reward and active management-by-exception) on subordinate creativity is partially mediated by the subordinate empowerment.

We have examined inhibitory erects on gasritis using omeprazole-cholestyramine resinate, which has been developed to increase the stability of omeprazole, the well-known proton pump inhibitor, in an acidic condition. To test the pharmacological action of this, we investigated the effect of omeprazole-cholestyramine resinate on indomethacin-induced gastritis in rats. Omeprazole was used as a reference drug. Orally administered omeprazole-cholestyramine resinate inhibited the indomethacin-induced gastritis in a dose-dependent manner. The inhibitory effect of omeprazole-cholestyramine resinate on the gastritis was similar to that of reference drug. In addition, rectal adminstration of the omeprazole-cholestyramine resinate inhibited the indomethacin-induced gastritis in a dose-dependent manner. The inhibitory effect of omeprazole-cholestyramine resinate was equipotent to reference drug. The basal gastric acid secretion was decreased when it was administered either orally or rectally. This inhibition of omfprazole-cholestyramine resinate was similar to that of omeprazole. These data suggest that omeprazole-cholestyramine resinate inhibit the gastritis in rats, and are comparable to omeprazole available in market.

In order to study the effects of Aloe vera Linne treatment on the clinical chemistry in patients with liver disease, seven patients were administered orally with 800~1, 600 mg of Aloe vera Linne four times day for six months. The high levels of serum AST, ALT, ALP, ${\gamma}$-GTP and total bilirubin in patients were significantly reduced by adminstration of Aloe vera L. The reduced serum albumin/globulin value was increased by Aloe vera L. treatment. But other blood parameters of clinical chemistry values were not affected by Aloe vera L. treatment. These data suggest that Aloe vera L. can be effective in treatment of the patients with liver disease.

대기부품은 대기기간 중에 우발적 고장이 발생할 수 있으며(type I failure), 해당상황이 장기간 방치되는 것을 방지하기 위해 주기적인 검사를 하는 것이 일반적이다. 그러나 검사가 대기기간 중 발생한 고장을 확인할 수 있게 하는 반면, 검사를 시작할 때 대기하던 부품에 부하를 가하는 과정에서 고장을 유발할 가능성이 존재하며(type II failure), 검사시간동안 대기부품을 작동시킴으로써 열화에 의한 고장발생(type III failure)의 가능성을 증가시키는 효과도 존재한다. 이에 본 논문은 주기적 검사정책을 갖는 대기부품을 대상으로 세 종류의 고장 가능성을 확률적으로 고려하여 성능분석을 실시하였으며, 성능을 평가하는 척도로 극한가용성을 사용하였다. 특히 type III failure를 고려하는 것은 기존에 연구되지 않은 부분으로 본 논문의 기여점이라 할 수 있겠다. 또한 수치해석을 통해 가용성의 관점에서 전술한 세 가지 유형의 고장특성과 검사주기와의 관계를 파악할 수 있도록 하였으며, 그 결과를 통해 높은 수준의 신뢰성 확보가 목적인 대기시스템의 효율적인 운영을 위한 의사결정시 도움이 될 수 있도록 하였다.

Standard temperature and absolute humidity weather correlations of Seoul for dynamic energy simulation have been developed regressing the measured data compiled by the Korea Meteorological Adminstration during a 10-year period from 1991 to 2000. The mathematical equations can generate the daily and yearly variations of outdoor weather data with consistency unlike the measured data which may show abnormal behavior, Considering that each hour of the day follows a certain yearly pattern, the correlations are developed for each hour. The derived 24 simple mathematical equations can be used for estimating outdoor temperature and humidity conditions for any arbitrary time of the year.

The metabolism of p-methoxycinnamic acid (p-MCA) has been studied in man and rabbits. Possible compounds were examined for metabolites by crystalization and by paper chromatography, which excreted after adminstration of p-MCA by stomach tube and intravenous injection. p-Methoxyhippuric acid was isolated from urine. Although pure glucuronide was not crystallized from urine, product was obtained by basic lead salt method, which gave p-methodxybenzoic acid (p-MBA) on hydrolysis and gave an intese naphthoresorcinol reaction. No evidence for the demethylation of p-MCA was found. These results are indicating that p-MCA may be mainly converted to p-MBA by ${\betha}$-oxidationand excreted as its conjugates with glycine and glucuronic acid. Its oxidation does not appear to be dependent on intestinal micro-organisms.
