김주헌(Ju Hun Kim),이은택(Eun Taik Lee),김덕재(Duck Jae Kim) 한국강구조학회 1995 韓國鋼構造學會誌 Vol.7 No.2

Based on the existence of a yield surface and a bound surface which represents the maximum stress state the material ever experienced, a plasticity model is modified to describe the behaviour of metal under nonproportional loadings. This paper is concered with the improvement of a plasticity model of the two surface type for structural steel based on experimentally observed features of 304 stainless steel specimens tested under axial torsional cyclic nonproportional loading condition at room temperature performed by Medowell. The proposed model is verified through an experimental program that includes different combinations of nonproportionally applied forces performed by Lee.

Quality properties in the sausage stuffed into the irradiated natural lamb and pork intestine for manufacturing the high quality emulsion-type meat produces were studied. The microbial changes of irradiated casings and the microbial growth of the sausages with gamma-irradiated natural casings were observed. Population of Total aerobia bacteria was decreased by gamma irradiation, dependent upon the irradiation dose. The number of microflora in lamb and pork casings was reduced by about 5.5 log cycle at 5kGy. Population of total aerobic bactelia of sausages stuffed in non-irradiated lamb and pork casing was about 3.6 log cfu/g after just manufacture and was about 7 log after 10 day storage. However, population of total aerobic bacteria of sausages with 3 key-irradiated and 5 kGy-irradiated casings was 2.48 and 0.32 log in lamb, and 2.78 and 0.60 log in pork respectively. The sausages vacuum-packaged and stored were shown no chance in the 2-thiobarbituric acid reactive substances value during storage. Irradiated sausage showed the higher TBARS value than that of nonirradiatd control at 5-day with pork casing and at 10day with lamb casing. Shear force of the sausages were decreased in both irradiated casings but the sensory evaluation showed no difference. Therefore, the gamma irradiation was a useful tool to sanitize the natural pork and lamb casings and extend the shelf-life of the high quality, value-added sausage made with those casings.

이종훈,조주연 大韓神經精神醫學會 1998 신경정신의학 Vol.37 No.1

저자는 요통을 호소하는 입대한 장병들의 정신의학적 특성을 알아보기 위해 본 연구를 시도하였다. 환자군은 1996년 9월 6일부터 11월 15일사이에 ○○사단 신병교육대에 입대한 48명이고, 대조군은 이들과 같은 시기에 입대한 장병중에서 통증을 호소하지 않는 장병 48명을 무작위 추출하였다. 각 군은 MMPI, Beck의 우울척도, Zung의 자가통증척도, 그리고 Barron의 자아강도척도를 실시했다. 자료는 chi-square test 또는 t-test에 의해 분석되었다. 검사의 결과는 다음과 같다. 1) 인구학적 변인상 환자군이 경제적으로 낮은 계층에 더 많이 분포한다(p<.05). 2) Beck의 우울척도와 Zung의 자가통증 평가척도는 환자군에서 유의하게 더 높았다(p<.01). 3) 다면적 인성검사에서 양군 모두 각 척도별 T 점수의 평균값은 정상범위 내에 있었다. 4) 다면적 인성검사는 환자군에서 척도 Pa(p<.05)와, 척도 F, Hs, D, Hy, Pd, Pt, Sc(p<.01)가 유의하게 더 높은 점수를 보여주었다. 5) 자아강도척도는 환자군에서 대조군에 비해 더 낮았다(p<.01). 이와 같은 소견은 요통환자가 정서적인 요인들과 강하게 관련되어 있다는 기존의 가설을 강하게 지지하고 있다. Objectives & Methods : The authors had attempted to find psychiatric characteristics of recruites who had complained lumbar pain. The patient group were 48 recruites who had admitted at recruit training center of the OO division from September 6 1996 to November 15 1996. The control group were 48 healthy recruites who had been chosen randomly during the same period. Each group had been examined by MMPI, BDI(Beck's depression inventory), Zung's self-rating pain & distress scale, and Barron's ego strength scale. The data were analyzed by chi-square test or t-test. Results : The results of this study were as follows : 1) On demographic data, patient group had distributed more common in lower level of economic status(p<.05). 2) The score of BDI & Zung's self rating pain & distress scale of patients group were significantly higher than those of control group(p<.01). 3) The mean T-score on each scale were within normal rang in both group. 4) The group of patients showed significantly higher score on scales of Pa(p<.05), and scales of F, Hs, D, Hy, Pd, Pt, Sc(p<.01). 5) Ego strength of patients group was significantly lower than that of control group(p<.01). Conclusion : This finding supports the existing hypothesis that lumbar pain patients are strongly related to emotional factor.

이종훈,조주연 大韓神經精神醫學會 1999 신경정신의학 Vol.38 No.5

연구목적과 방법 : 저자는 군복무기간에 따른 우울, 불안, 충동성향을 평가하기 위하여 548명의 병사들에게 Beck의 우울척도(BDI), Zung이 개발한 자가평정 불안척도(SAS), Barratt이 개발한 충동성 검사(BIS)를 실시하였다. 일반 병사들은 다음과 같이 3군으로 나뉘어졌다. 제1군 : 군복무기간이 8개월이하인 병사 제2군 : 군복무기간이 9개월에서 16개월인 병사 제3군 : 군복무기간이 17개월이상인 병사 결 과 : 1) 제1군의 우울척도 총점(F value=3.60, p<.05)과 부정적 자기상/정신운동지연의 하부척도 점수(F value=5.82, p<.01)가 제2군의 것보다 의미있게 더 높았다. 2) 제1군의 자가평정 불안척도 점수가 다른 두 군에 비해서 의미있게 높았다(R value=5.80, p<.01). 3) 제1군의 총충동점수(F value=3.42, p<.05)와 운동충동점수(F value=3.29, p<.05)가 제3군에 비해 의미있게 높았다. 결 론 : 비록 병사들의 각 척도별 측정평균점수는 정상범위에 속할지라도, 이번 연구의 결과는 제1군의 경우 다른 두 군에 비해 더 우울하고, 불안하고, 충동적이라는 것을 말한다. 따라서 군복무기간중 사고를 방지하기 위해서, 우리는 군복무기간이 8개월 이하인 사병의 경우 더 많은 주의와 관심을 가지고 관리해야 되겠다. Objectives & Methods : The authors applied Beck's Depression Inventory(BDI), Self-rating Anxiety Scale(SAS) and Barratt Impulsiveness Scale(BIS) to 548 enlisted men to evaluate the differences of anxious, depressive and impulsive trends according to the duration of the military service. The enlisted men were divided into 3 groups as follows : Group 1 : those who had served under 8 months. Group 1 : those who had served from 9 to 16 months. Group 1 : those who had served over 17 months. Results : 1) The scores of BDI(F=3.60, p<.05) and negative self image and psychomotor retardation subscale(F=5.8, p<.01) of group 1 were significantly higher than those of group 2, respectively. 2) The SAS score of group 1 was significantly higher than that of others(F=5.80, p<.05). 3) The scores of total BIS(F=3.42, p<.05) and impulsiveness-motor subscale(F=3.29, p<.05) of group 1 were significantly higher than those of group 3, respectively. Conclusion : In spite of their scores were in normal range, these results suggest that the enlisted men of group 1 are more anxious, depressive and impulsive than those of the others. So we should give more attention to them and offer more concerns for them to protect the military accident.

석주원,김성장,곽희숙,이창훈,김인주,김용기,배영태,김동수 대한핵의학회 2002 핵의학 분자영상 Vol.36 No.6

목적: hNIS는 갑상선 조직 외에 다른 조직들에서도 발현된다고 알려져 있다. 유방암 세포는 그런 조직들 중에 하나이며, 그에 의한 유방암의 방사성옥소치료의 가능성이 제시되고 있다. 본 연구에서는 유방암 조직에서 hNIS의 발현정도를 알아보고, ^99mTc-MIBI 유방스캔과 hNIS의 발현 정도와의 관계를 조사하여 보았다. 대상 및 방법: 본 연구에서는 유방암으로 수술을 시행했던 56명의 환자를 대상으로 하였다. hNIS의 발현은 면역조직화학염색에 의해서 평가되었으며, 그 결과를 ^99mTc-MIBI 유방스캔의 판정 결과와 비교하였다. 결과: 전체 56명의 환자에서 hNIS의 발현율은 41.1%였다. 병리학적 진단에 의해 침윤성관상피암종이었던 49명에서의 발현율은 42.9%, 관상피내암종이었던 7명에서의 발현율은 28.6%였다. ^99mTc-MIBI 유방스캔에서 국소섭취 소견이 관찰되었던 41명에서의 hNIS의 발현율은 31.7%였다. 비정상적인 섭취 소견이 관찰되지 않았던 15명의 환자에서의 hNIS의 발현율이 의미있게 높게 관찰되었다(66.7%, p>0.05). 결론: 유방암 환자에서의 hNIS의 발현율은 그다지 높지 않았다. ^99mTc-MIBI 유방스캔에서 섭취증가 소견이 없을 때 hNIS의 발현율이 더 높았다. Purpose: Human Na^+/I- symporter (hNIS) is known to be expressed in many tissues other than thyroid gland. The breast cancer cells are one of them and the possibility of radioiodine therapy in treatment of the breast cancer may be suggested. We investigated the expression rate of hNIS and the relationship between the expression of hNIS and the finding of 99mTc-MIBI scintimammography in the breast cancer. Materials and Methods: Surgically proved 56 patients with breast cancer were the subjects of this study. The expression of hNIS were evaluated by immunohistochemistry and the results were compared to the findings of 99mTc-MIBI scintimammography. Results: Overall expression rate of hNIS was 41.1% in 56 patients. According to the pathologic diagnosis, it was 42.9% in 49 patients with invasive ductal carcinoma and 28.6% in the 7 patients with ductal carcinoma in situ. The expression rate of hNIS in the 41 cases with a focal increased uptake at he breast lesion on 99mTc-MIBI scintimammogram was 31.7%. That in the 15 cases without any abnormal uptake on the scan was significantly higher(66.7%, p<0.05). Conclusion: The expression rate of hNIS in the patients with breast cancer was not so high. The rate was higher in the patients with no increased uptake at the breast lesion on 99mTc-MIBI scintimammography. (Korean J Nucl Med 2002;36;325-32)
