본 연구는 만 2~5세 영·유아의 발달 상태를 객관적으로 평가함과 동시에 발달이 지연된 영·유아를 선별할 수 있는 발달평가도구 문항을 개발하기 위한 예비연구이다. 이를 위해 문헌고찰 및 발달관련 평가도구들을 비교 분석하여 발달지표를 선정하고, 만 2세~5세까지의 영·유아의 언어, 인지, 사회·정서발달영역을 교사관찰에 기초하여 평가할 수 있는 문항을 개발하였다. 연구대상은 대도시, 중소도시, 읍면 소재지 별로 표집 된 만 2세부터 5세까지 총 13개 유아교육기관에 다니는 435명의 영·유아들이며, 본 연구에서 최종 개발된 평가도구의 문항은 총 141문항이다. 평가도구 문항은 언어, 인지, 사회·정서발달영역별로 영·유아의 행동과 언어를 중심으로 교사가 관찰하고, 관찰하기 어려운 문항에 대해서는 단서와 kit를 제시하여 평가할 수 있도록 구성하였다. 개발된 평가도구 문항의 적절성을 알아보기 위하여 내용 타당도와 내적 신뢰도를 살펴본 결과 비교적 양호한 것으로 나타났다. This was a preliminary study to construct a developmental rating scale for understanding children's objective developmental levels and screening developmental disabilities. For this purpose, a developmental indicator was selected by a literature review and comparative analysis of related developmental assessment tests. An assessment scale based on teacher's observations to measure language, recognition, and social-emotional developmental areas was developed. The subjects were 435 young children aged 2 to 5 who lived in both urban and rural areas. A trial test consisted of 141 assessment items in the language, recognition, and social-emotional developmental domains. The developmental scale was evaluated by teachers who observed children's behavior and language, and used clues and kits. Tests on validity and reliability for confirming the appropriateness of the developed assessment scale showed that content was relatively valid and internally consistent.

The purpose of this study was to investigate correlation between the isokinetic leg strength and anaerobic exercise capacity from Wingate ergometer test in women soccer players. 30 females soccer players performed two exercise test. Anaerobic exercise capacity variables including peak power(WPP), mean power(WMP), peak anaerobic power(WPAP) and peak anaerobic capacity(WPAC) test were analyzed using Wingte cycle ergometer test(30sec) and isokinetic leg strength variables including peak torque(PT), average power(AP) and set total work(STW) were analyzed using Cybex 770 iskokinetic device(60, 90, 180°/sec, 5, 10, 25repetitions, respectively). Isokinetic leg strength variables was calculated by the mean value of both knee(legt and right). The experimental results from this study are the following: There were a significant positive correlation between WPP and WMP and PT of knee extension in comparison with knee flexion. PT of knee extension at 60°/sec had the highest positive correlation with WPP(r=.789, p=.000). And WMP had the highest positive correlation with PT of knee extension at 180°/sec. Also, there were a significant positive correlation between WPAP and WPAC and PT of knee extension in comparison with knee flexion. WPAP had the highest positive correlation with PT of knee extension at 90°/sec (r=.765, p=.000)and WPAC had the highest positive correlation with PT of knee extension at 180˚/sec(r=768, p=.000). In conclusion, anaerobic exercise capacity using Wingate test had a significant positive correlation with PT of knee extension. However, because little is known about the correct measurement and evaluation the soccer fitness of women soccer players, it is necessary to study about the improvement of various soccer fitness of women soccer players.

초고진공에서 공상에피택시(solid-phase epiyaxy, SPE) 방법으로 CoSi₂를 Si(111)기판 위에 에피택시 성장시켰다. 2MeV⁴He++ ion후방산란 분광기와 사중결정 x-선 회절기 및 고분해 투과전자 현미경을 이용하여 성장된 CoSi₂의 상과 조성, 결정성, 그리고 계면의 미시구조를 조사하였다. 초고진공상태의 실온에서 Si(111)-7X7기판에 Co를 약 20 ~50 ?? 중착한 후 SPE에 의하여 실리사이드를 형성시키는 경우 600℃에서는 B-형의 CoSi₂가, 그리고 700℃에서는 A형의 CoSi₂가 선택적으로 에피택시 성장하였으며, 정합성은 B-CoSi₂[110]//Si[110] and CoSi₂(111)//Si(111)이, 그리고 700℃에서는 A-CoSi₂[110]//Si[110], CoSi₂(002)//Si(002)을 나타내었다. Epitaxial films of CoSi₂were grown on Si(111) substrates by in situ solid-phase epitaxy in a ultrahigh vacuum. The phase, the chemical composition, the crystallinity, and the microstructure of the Silicide/Si interface were investigated by 2-MeV⁴He++ ion-backscattering spectrometry, quadruple crystal X-ray diffractometry, and high-resolution transmission eletron micorscopy. High-quality films of either B-type or A-type CoSi₂ could be grown selectively on Si(111) substrates by depositing ~ 20 ~ 50 ?? of Co on a Si(111)-7X7 substrate followed by in situ annealing at 600℃ or 700℃ for 10 min. The matching face relationships are CoSi₂[110]//Si[110] and CoSi₂(111)//Si(111) by B-type CoSi₂ and CoSi₂[110]//Si[110]//Si[110] and CoSi₂(002)//Si(002) for A-type CoSi₂.

Citrobacter species is a gram-negative bacilli that can cause opportunistic infections in immunocompromised hosts. Citrobacter braakii refers to the genomospecies 6 of the Citrobacter freundii complex. There are no detailed studies on infections caused by this newly identified specific genetic species in Korea. We herein report a case of a patient with hepatocellular carcinoma who, after undergoing transcatheter arterial chemoembolization, developed biloma which later progressed to C.braakii sepsis and did not respond to treatment. To our knowledge, this is the first reported case in Korea on C. braakii infection resulting in septic shock in a patient with malignancy in Korea.

Objectives: In order to evaluated the prevalence and the site of infection of cytomegalovirus in terminally failing heart, cytomegaloviral DNA was detected in the explanted hearts of transplantation recipients. Methods: DNA extractions were performed from explanted failing hearts(N=22) and normal hearts(N=5) and polymerase cain reactions(PCRs) were done for detection of late gene sequence coding pp150 glycoprotein. The products were confirmed by electrophoresis on the 1% agarose gel. n order to improve the detectability of cytomegaloviral genome, nested PCRs were executed with the primers designed for the original 607 bp products. In situ PCRs also were done with the samples which were confirmed as positive for CMV viral genome by nested PCRs. Results: All patients had IgG anti-cytomegalovirus antibody and did not have IgM anti-cytomegalovirus antibody. Cytomegaloviral genomes in myocardium were detected by polymerase chain reaction. The 607bp products by PCRs were found in both explanted failing heart(3 cases/22. 13.5%) and normal hearts( 1 case/5, 20.0%). In nested PCRs, 186bp products were found in both failing hearts(LV 4/22, LA 3/2, RV 4/22, RA 0/17) and normal hearts(LV 2/5, LA 1/4, RV 2/5, RA 2/5). These was no significant change in positivity of cytomegaloviral DNA genome between failing and normal hearts. Total positivity of cytomegaloviral genome in explanted hearts was 44.4% according to the nested PCR results. The positivity of cytomegaloviral DNA by n situ PCR was 33.3%(4/12), and the site of positive reaction was the nuclei of the myocardial cells. Conclusion: Cytomegalovirus was rarely observed in explanted hearts of terminal heart failure and nested PCR could enhance the sensitivity of cytomegaloviral genome detection. The result of the in situ PCR showed the site of the cytomegaloviral infection was nuclei of the myocardial cells. Cytomegalovirus, however, might have no direct causal relationship in the development of terminal heart failure.

이영호,심주철,이상경,서영수,김용관,김규수,김영훈 大韓神經精神醫學會 2000 신경정신의학 Vol.39 No.3

연구목적 : 본 교실에서 정신분열병 환자 가족을 대상으로 시행 중인 장기 정신교육적 가족치료모형을 소개하고, 이모형이 가족의 대처방식과 우울증상, 환자가 자각하는 가족의 정서적 지지와 우울증상, 재입원율 및 사회재활상태에 미치는 영향을 평가하였다. 방 법 : 연구대상은 DSM-IV 진단기준에 의해 정신분열병으로 진단받고 외래 통원치료를 받고 있는 환자와 그 보호자였다. 교육군은 전체 19회 교육 중 최소 ⅔이상 참여한 11명의 환자와 가족이었고 비교육군은 부산소재의 종합병원에서 가족교육을 받지 않고 통원치료만을 받았던 11명의 환자와 가족이었다. 정신교육적 가족치료 모형의 효과는 가족의 대처방식과 우울증상, 환자가 자각하는 가족의 정서적 지지와 우울증상, 재입원율, 사호재활 실태로 나누어 평가했다. 평가도구는 The Ways of Coping Checklist의 국내번안용, Family Emotional Support Questionnaire for Transaction. Beck Depression Inventory를 이용했다. 재입원율 및 사회재활 실태에 대한 평가는 환자 및 가족과의 면담을 통해 조사했다. 결 과 : 본 연구의 정신교육적 가족치료 모형 실시 후 가족의 대처방식 중 적극적 대처는 교육군운 의미있게 증가한 반면 비교육군에서는 변화가 없었다. 소극적 대처 교육군은 의미있게 감소했으나 비교육군에서는 변화가 없었다. 가족치료모형 실시 전 가족들은 양군 모두 심한 우울증상을 갖고 있었다. 가족치료모형 실시 후 가족의 우울증상은 교육군에서 감소, 비교육군은 증가를 보였으나 통계적 유의성은 없었다. 환자가 지각하는 가족의 정서적 지지 평가척도점수는 교육군은 의미있는 증가를 보였으나 비교육군에서는 변화가 없었다. 환자의 우울증상의 교육군에서는 현저한 감소를 보인 반면 비교육군은 상반되게 증가했다. 가족의 적극적 대처가 환자가 자각하는 정서적 지지의 증가 및 우울증상 감소와 의미있는 상관관계를 나타냈다. 또한 교육군의 환자들이 비교육군의 환자들보다 장기가족교육 종료시점과 9개월 경과 후의 추적 평가에서 재입원율이 현저히 낮았고, 사회재활상태도 좋았다. 결 론 : 본 연구에서 실시된 장기 가족교육모형은 가족의 대처방식을 향상시키고, 우울증상의 감소를 가져오며, 환자가 자각하는 가족의 정서적 지지 향상 및 우울증상의 호전을 가져오고, 재입원율의 저하 및 사회재활의 향상을 보이는 것으로 나타났다. Objectives : This study was performed to introduce a psychoeducational family therapy model for the families of schizophrenic patient and to investigate the effect of this model on the changes in coping style and depressive symptoms of the family members, and in perception of emotional support by families and depressive symptoms of patients. Methods : Subjects were schizophrenic out-patients, who fufilled DSM-IV diagnostic criteria, and their families. The members of "education group" were 11 families and patients who participated in more than two thirds of 19 sessions of the program. The members of "non-education group" were 11 families and patients who had no experience of family education and were treated in a general hospital in Pusan. Clinical ratings were performed using by The Ways of Coping Checklist, Family Emotional Support Questionnaire for Transactions, and Beck Depression Inventory. Results : Coping style was changed positively, in education group but not in non-education group. The depressive symptoms of families were decreased in educated group and increased in non-educated group, although there were no statistical significance. In education group, patients felt much better emotional support by their families than patients in non-education group did. At the same time, their depressive symptoms were significantly reduced. The patients from education group were on more successful rehabilitation than those from non-education group were. Conclusion : Our results suggest that this psychoeducational family therapy model would be helpful to induce the positive changes in coping styles and reduce the depressive symptoms of family members, and it could also induce the reduction of depressive symptoms of schizophrenic patients and help their rehabilitation.
