Prediction of retained austenite fraction is quite important in designing advanced high strength steels since retained austeniteis the source of transformation-induced plasticity. The present study investigates the phase constitution of a medium-carbonQ&P steel by comparing various approaches to the transformation stasis of bainitic ferrite and applying them to the partitioningprocess. Among them, the modified GEB approach gave the best agreement with the experimental observation, includingthe effects of heat-treatment condition and chemical composition on phase constitution. This indicates phase transformationduring partitioning can be effectively described by the physics of Gibbs energy balance approach.

배경 : 헤르페스바이러스과에는 단순포진 바이러스(HERPES SIMPLEX VIRUS, HSV), 수두대상포진 바이러스 (VARICELLA-ZOSTER VIRUS, VZV), 엡스타인-바 바이러스 (EPSTEIN-BARR VIRUS, EBV), 그리고 거대세포 바이러스 (CYTOMEGALOVIRUS, CMV) 등이 있다. 헤르페스바이러스 감염은 혈액암환자에서 조혈모세포 이식 환자에서 전파 (dissemination), 이차감염, 세균 중복 감염의 심각한 합병증을 일으킬 수 있다. 하지만 항암약물치료를 받는 림파종 환자에서 항 바이러스 약제의 사용 용량과 기간에 대한 concensus는 없다. 헤르페스바이러스 감염에 대한 발생율과 위험인자를 후향성으로 분석하였다. 방법 : 고신대학교 복음 병원에서 1995년 6월부터 2009 년 2월 사이에 새롭게 진단되어 조혈모세포 이식을 받은 전체 58명의 환자들이 후향적으로 현 연구에 등록했다. 헤르페스 바이러스 감염은 임상적 진단, 혈청학적 검사 또는 병리학적 진단에 기초하여 확진한다. 환자들의 특성은 다음과 같다: 평균 연령은 44세 (범위 19-62세)였고 남녀비는 30:28이었다. 등록된 질환은 백혈병 (n=9, 15.5%), 림프종 (n=30, 51.7%), 다발성 골수종 (n=12, 20.7%), 재생불량성 빈혈 (n=6, 10.3%) 그리고 골수이형성증후군 (n=1, 1.7%)이 포함되었다. 결과는 chi-squre test나 independent samples T test를 사용하여 분석되었다. Multivariate analysises에 대해 logistic regression test를 사용하였다. 결과 : 15명의 환자들 (25.9%)에서 조혈모세포 이식후 헤르페스 바이러스 감염이 발생하였다. 조혈모세포 이식 5년간 누적 발생율은 53.9%였다. Univariate analyses에서 헤르페스 바이러스 감염에 대한 유의한 위험 인자는 없었다. 하지만 조혈모세포 이식후 생존 기간(40.18 ± 30.14 months vs 20.06 ± 26.67 months, p=0.018)은 헤르페스 바이러스 감염의 낮은 발병율과 유의한 관련성이 있었다. 이식 편대 숙주질환 (GVHD)의 존재 (37.5% in developed GVHD vs 0% in no GVHD, p=0.200), 동종조혈 모세포 이식에서 면역억제요법의 기간 (15.98 ± 14.02 months vs 6.78 ± 3.67 months, p = 0.374)은 헤르페스 바이러스 감염에 대한 위험인자가 아니었다. 결론 : 조혈모세포 이식 후 생존 기간은 어사이클로비어 예방을 받은 혈액암 환자에서 헤르페스 바이러스 감염의 낮은 발병율과 연관성이 있는 것으로 보인다. 저용량의 어사이클로비어 예방은 헤르페스 바이러스 감염의 고위험군인 조혈모세포 이식을 받은 혈액암 환자에 필요하리라 생각된다. Background : Herpesviridae family includes herpes simplex virus, varicella zoster virus, Epstein-Barr virus, and cytomegalovirus, etc. Herpesviridae viral infection (HVI) can lead to serious complications including dissemination, secondary infection, bacterial superinfection in patients with hematologic malignancy following hematopoietic stem cell transplantation (HSCT). But there was no consensus on the dose and duration of antiviral agents prophylaxis in patients undergoing chemotherapy. We retrospectively analyzed the incidence and the risk factors for HVI. Method : A total of 58 patients who newly diagnosed and received HSCT with prophylaxis of acyclovir at the Kosin University Gospel Hospital, Busan, Korea between June 1995 and February 2009 were enrolled retrospectively in the current study. HVI was confirmed based on clinical diagnosis, serologic test or pathologic diagnosis. The characteristics of the patients were as follows: the median age was 44 years (range 19-62 years) with a female-to-male ratio of 30:28. The enrolled diseases included leukemia (n=9, 15.5%), lymphoma (n=30, 51.7%), multiple myeloma (n=12, 20.7%), aplastic anemia (n=6, 10.3%) and myelodysplastic syndrome (n=1, 1.7%). The results were analyzed using a chi-square test and independent samples T test. For the multivariate analysis, we used logistic regression test. Results : Fifteen patients (25.9%) developed HVI after HSCT. The cumulative incidence of HVI was 53.8% at 5 years after HSCT. In univariate analysis, there was no significant risk factor for HVI. The presence of graft-versus-host disease (GVHD) (37.5% in developed GVHD vs. 0% in no GVHD, p=0.200), duration of immunosuppressive therapy (IST) in allo-SCT (15.98 ± 14.02 months vs. 6.78 ± 3.67 months, p = 0.374) were not risk factors for HVI. Conclusion : The incidence of HVI was similar to that in historical other studies. There was no risk factor associated with development of HVI. Most of the HVI occurred within the first 24 months after transplantation. So long term use of antiviral prophylaxis may be needed to prevention of HVI after HSCT.

Osteoporosis is the consequence of an imbalance between osteoclastic and osteoblastic activity, coupled with an increased rate of bone turnover observed with menopause. Estrogen is generally considered to maintain bone mass through suppression of bone resorption. The purpose of this study was to evaluate the rat femoral trabecular change not only in the deficiency of estrogen but also in the administration of estrogen following ovariectomy(OVX). 30 female Sprague-Dawley rats were subjected to bilateral OVX or sham surgery(control). Groups of OVX were divided into 4 groups. The first group was injected daily with vehicle alone for 20 days after 20 weeks following OVX. The additional groups of OVX was injected daily with low, medium, or high doses of 17β-estradiol(10, 25 or 50㎍/kg BW, respectively) . All rats were sacrified 23 weeks after OVX, and their femur were processed for H&E. MT stain and histomorphometry. The results were as follows ; 1.In the histomorphometric analysis, the trabecular bone volume/tissue volume, trabecular thickness and trabecular seperation were respectively 31.2±8.3%, 54.3±4.8㎛ and 280.7±16.4㎛ in vehicle treated OVX group and 48.6±7.3%, 90.4±4.5㎛ and 126.3±5㎛ in sham operation group, and they showed statistical significance compare to control group. 2.The trabecular bone volume/tissue volume, trabecular thickness and trabecular separation were respectively 44.4±4.3%, 109.5±12.3㎛ and 94.9±8.5㎛ in low doses of 17β-estradiol injected group and they showed statistical significance compare to OVX group. 3.The trabecular bone volume/tissue volume, trabecular thickness and trabecular separation were respectively 44.4±4.3%, 109.5±12.3㎛ and 94.9±8.5㎛ in medium doses of 17β-estradiol injected group and they showed statistical significance compare to OVX group, but they didn't show statistical significance compare to low does of 17β-estradiol injected group. 4.The trabecular bone volume/tissue volume, trabecular thickness and trabecular sepatation were respectively 46.4±4.5%, 154.4±13.2㎛ and 113.7±12.8㎛ in high doses of 17β-estradiol injected group and they also showed statistical significance compacre to OVX group, but they didn't show statistical significance compare to other experimental groups. From the above results, metaphyseal bone formation was markedly reduced in OVX rate but treatment of OVX rats with 17β-estradiol resulted in normalization of femur trabecular bone volume. But they didn't show statistical significance the effect of bone formation according to the dose dependency.

人間으로서의 존엄과 價値 : 憲法 第8條의 解釋을 中心으로

金成勳 제주한라대학 1975 論文集 Vol.1 No.-

Ⅰ. Preface The dignity and value as human beings will be studied, centered on the explation of Article 8 of the constitution of Korea, and on the relationship with Article 32, The Article 8 and 32 are as fallows: Article 8 : All citizens shall have the dignity and value as human beirgs, and it shall be the duty of the state to guarantee fundamental rghts of the people to the utmost. Article 32 : ① Liberties and rights of the citizens shll not be ignored for the reasons that they are not enumerated in the constitution. ② All liberties and rights of citizens may be restricted by law only in casesdem and necessary for the maintenance of order and public welfare. In case of such restriction, the essential substances of liberties and rights shall not be infringed. Ⅱ. The history and development of the human dignity rights. Modern democracy has its own value on the individualism and liberalism principled by human dignity and value. And owing to the emergence of totalitarianism and communism to deny the dignity and value of human beings after the World War Ⅰ, post World War Ⅱ every nation has come to regulate them in its constitution. Ⅲ. Contents and significance The dignity of signifies the contents of personality considered as its essence, and its value signifies an absolute estimate of man. The rights of dignity is true even of foreigners or those who lose citizenships but not of a corporate body. As the dignity and value of man have this two fold aspect of being spiritual and economic, the value security of them reguires that of the individual freedom and rights to live a human life. Ⅳ. The legal offect of human dignity rights As the security of human dignity and value -that of all citizens fundamental rights-is the rightful duty of government, all powers of a nation should be centered on the defence of human dignity and value, which is also thought to be applied indirectly to private laws. Ⅴ. The legal character of Article 8 of the Constitution The Article 8 is a basic norm which has regulated the thought of respect of fundamental rights and placed the superiority of individual before government as far as the fundamental rights are concerned. Ⅵ. The restrictions of human dignity righis As the human dignity and value are essential contents of fundamental rights, they may not be restricted thanks to Article 32, clause 2.

金洋,鄭聖勳,金日出 고신대학교 자연과학연구소 1997 고신대학교 자연과학연구소 논문집 Vol.7 No.-

이중고리 착물인 diaminosarcophaginecobalt(Ⅲ)과 aminomethylsarcophaginecobalt(Ⅲ)의 다양한 pyridylmethyl 기 유도체를 합성하고 특성을 조사하기 위하여 알킬화제로써 2- 및 4-pyridylaldehyde를 이용한 알킬화 반응이 적용되었다. 얻어진 유도체는 mono- 및 dipyridylmethyl 기가 치환된 혼합물로써 높은 수득률로 얻어졌다. 생성물에 대한 X-선 결정학, uv/visible 분광학, 원편광이색성 분광학, nmr 분광학의 특성을 조사하였다. Cage 착물의 일차 amine의 알킬화는 착물의 배위특성에 거의 영향을 주지 않는 것으로 나타났다. 착물의 리간드장도 또한 cage의 1 및 8 위치에서의 알킬화에 의하여 거의 영향을 받지 않는 것으로 나타났다. Cage 착물의 광학활성은 imine 기의 환원이 진행되는 동안에도 유지되었다. 고체상태에서 pyridyl 치환기는 π-π 상호 작용에 의하여 겹쳐져 있었다. Uv/vis 스펙트럼과 X-선 결정구조의 조사에 의하여 cobalt(Ⅲ) 이온 주위의 ethylenediamine 고리가 lel₃ 비치를 가지는 것으로 알려졌다. Alkylation reaction involving 2- and 4-pyridylaldehyde as alkylating reagents was adopted to synthesise and characteries several pyridylmethylated derivatives of the bicyclic complexes, "diaminosarcophagine-cobalt(Ⅲ) " and "aminomethylsarcophaginecobalt(Ⅲ)". The obtained derivatives were found to be the mixture of mono- and dipyridylmethylated complexes in high yield. The products were characterised by X-ray crystallography, uv/visible spectroscopy, circular dichroism spectroscopy, nmr specrtometry. The alkylation of the primary amines of cage complex appeared to have little effect on the coordination characteristics of the complex. The ligand field of the complexes also appeared to be little affected by the alkylation on the 1 and 8 positions of cage. The optical activity of cage complexes was retained during the reduction of imine groups proceeded. In the solid state, pyridyl substituents were stacked due to π -π interaction. By investigating uv/vis spectrum and X-ray crystal structure, it was found that ethylenediamine rings around cobalt(Ⅲ) ion had lel₃ conformation.
