공기화,최동식 부산교육대학교 초등교육연구소 2003 초등교육연구 Vol.18 No.-

The most common model of teaching games in elementary school is Technique Oriented Appreach model, instructions of this model are in good order, and are performed games after which children are learned partial skills of game. Therefore this model instruction don't allow fun and motivation. The alternative game model is suggested for the Teaching Game for Understanding model(TGFU) by Bunker & Thorpe(1982). The TGFU model was adoped as a fundamental curriculum model in the 7th revision of the physical education in elementary school. Tag games are low organized one, but this games may be applied to the invasion and fielding/run-scoring games. 3rd-6th grades children in Jang-an elementary school performed tag game which were applied to the TGFU. This study were analyzed the opinions and portfolios of children and teaching diary of teacher, and were assessed instruction materials. The conclusion of this study are summarized as follows; 1. Not only ball games were well applied Teaching Games for Understanding model but also tag games. 2. Tag games ere improved the game contents and tactics recognition. 3. During children were performing tag games, they improved the execution capability and skills of games. 4. 3rd grade children were more prefer to tag games than the upper graders. 5. Children were developed creation of game were performed tag game process.

한국인의 치아우식 조절에 관한 연구 : Ⅱ.흰쥐 치아우식 이환율에 미치는 수종 양념의 영향에 관한 추가연구 Ⅱ. ADDITIONAL STUDIES ON THE EFFECTS OF THE SEVERAL SPICES ON THE CARIES RATE IN RATS

Those studies were performed to elucidate the effects of several dietary spices on dental caries and to determine which component of spices induced the change of incidence of dental caries in Sprague-Dawley rats which were supplied from SNU animal house. For this study, 132 rats (rats weighing 90-140 gm) were chosen at random with the same number of both sexes and divided into eleven experimental groups which contained the differential components of drinking water and diets for control and experimental group. Control group was fed standard cariogenic diet and tap water. In experimental groups, rats were fed standard cariogenic diet supplemented with capsicum (10%), ash capsicum (1, 10%), garlic (5%), common salt (3%), and analytical salt (3%) for 80 days. Drinking water was tap water containing water extract of capsicum (1, 10%), water extract of garlic (1.1%), and fluoride (50ppm). The results were as follows. 1. 54.6 in caries score was recorded in control group. 2. Rats which drank water containing 50ppm of fluoride showed 18.4% decrease in caries score. 3. Capsicum-fed rats showed 10.7% (capsicum 10%) increase in caries score and rats which drank water containing water extract of capsicum (1, 10%) showed 14.1% (w.e. capsicum 1%) and 0.16% (w.e. capsicum 10%) increase in caries score. But ash capsicum-fed rats showed 18.7% (ash capsicum 1%) and 7.3% (ash capsicum 10%) decrease in caries score. 4. Garlic-fed rats showed 22.1% (garlic 5%) decrease in caries score. But rats which drank water containing 1.1% of water extract of garlic showed 24.1% increase in caries score. 5. 58.4% and 68.0% increase in caries score were recorded in rats which were fed diet containing common salt (3%) and analytical NaCl (3%), respectively.

지동선,공용운 단국대학교 1999 산업기술연구 Vol.1 No.-

The solid-liquid phase separation of the high density polyethylene(HDPE) hollow fiber membrane prepared via thermally induced phase separation process was thermodynamically investigated. As the amount of liquid paraffin(LP) used as a diluent increased, the equilibrium melting temperature given Hoffman-Weeks plots decreased. The value of Flory-Huggins interaction parameter obtained from the melting point depression in the HDPE/LP blends was -0.43. The phase was not separated in the melt state since it had good miscibility. However, the solid-liquid phase separation occurred at lower temperatures. The temperatures of crystallization and phase separation decreased with increase in the cooling rate. As the amount of liquid paraffin and draft ratio increased, the flux of polyethylene hollow fiber membrane increased. It was found that the optimum blend ratio for microporous polyethylene hollow fiber membrane of HDPE/LP blends was determined to be 40/60. The flux of polyethylene glycol solution under the same applied pressure and time was less than that of pure water for HDPE/LP 40/60 and 50/50(wt%).

콘택트렌즈 보존 용기 유래 가시아메바 KA/L5주의 세포질 내에 존재하는 bacterial endosymbiont(내공생세균)를 투과전자현미경으로 관찰하여 확인하였다. 숙주인 가시아메바 KA/L5주는 형태학적으로 제2군에 속하였고, rDNA PCR-RFLP 결과 A. lugdunensis로 동정되었다. 미토콘드리아 DNA RFLP와 동위효소 분석상 이 충주는 국내 콘택트렌즈 보존용기에서 가장흔히 분리되는 type인 KA/Ll주, 국내 임상 분리주 중 하나인 KA/E2주, 내공생세균을 가지는 것으로 보고된 병원 냉각수 유래 KA/W4주 및 L3a주와 동일하거나 매우 유사한 성적을 보였다. 내공생세균은 약 1.38× 0.507㎛의 크기였고, 아메바 세포질 내에 불규칙하게 분포하고 있었으며. 그 표면에 아메바의 ribosome이 부착되어 있었다. 내공생세균을 둘러싼 lacunae나 막과 같은 구조는 관찰되지 않았다. Legionella 특이 primer를 이용한 효소중합반응(PCR)에서 내공생세균의 염색체 DNA는 증폭되지 않았다. A. lugdunensis의 우리말 이름을 담수가시아메바로 제안한다. Transmission electron microscopy of an Acanthamieba isolate (KA/L5) from a contact lens case revealed bacterial endosymbionts within cytoplasm of the amoebae, The Acanthamoeba isolate belonged to the morphological group II. Based on the polymerase chain reaction (PCR) - restriction fragment length Polymorphism (RFLP) of 18S ribosomal RNA coding DNA (rDNA), the Isolate was identified as A. lugdunensis. Strain typing by isoenzyme analysis using isoelectric focusing (IEF) and mitochondrial (Mt) DNA RFLP revealed that the isolate was closely related with KA/Ll , the most predominant type of isolates from contact lens storage cases, KA/E2, a clinical isolate, KA/W4, preciously reported to host endosymbionts, and L3a strains of A. lugdunensis. The endosymbionts were similar to those of KA/W4 In aspects that they were randomly distributed in both trophozoites and cysts, and were rod-shaped bacteria measuring approximately 1.38x 0.50㎛. But the number of endosymbionts per amoeba was significantly lower than that of KA/W4. They were neither limited by phagosomal membranes nor included In lacunae- like structure.

조진석,공지현,김진원,심경순,하준선,김철권,강동호,장정희,변원탄 大韓神經精神醫學會 1998 신경정신의학 Vol.37 No.5

목 적 : 사회기술훈련, 환자교육, 가족교육, 집단치료, 예술치료, 작업치료와 같은 포괄적인 정신재활 치료를 약물치료와 병행할 경우 약물치료만 시행할 때에 비해 정신분열병 환자의 재발율, 입원횟수, 입원일수, 직접 치료경비 등에 어떤 효과가 있는 지를 알아보기 위함이다. 연구방법 : 1993년 9월부터 1995년 2월까지 양산 신경정신병원의 폐쇄병동에서 퇴원한 20∼35세 사이의 정신분열병 환자 173명을 대상으로 46명에게는 6개월동안 정신재활 치료를 시행하였고 127명에게는 통상적인 외래치료만 시행한 후 연구시작 시점을 포함하여 2년동안 양군에 속한 환자들을 대상으로 재발율, 입원횟수, 입원일수, 직접 치료경비 등을 1년 단위로 추적 조사하였으며, 연구시작 시점을 기준으로 전과 후의 매년 평균 입원횟수, 입원일수, 직접 치료경비도 서로 비교하였다. 결 과 : 정신재활 치료를 약물치료와 병행할 경우 약물치료만 시행할 때에 비해 재발율, 입원횟수, 입원일수, 직접 치료비용이 현저히 감소되었다. 그리고 정신재활 치료를 받은 군에서는 치료 전에 비해 치료 후에 재발율, 입원횟수, 입원일수, 직접 치료비용이 유의하게 감소하였지만 통상적인 외래치료만 받은 군에서는 치료 전과 후간에 유의한 변화를 보이지 않았다. 결 론 : 정신분열병 환자들에게 정신재활 치료를 약물치료와 병행할 경우 약물치료만 시행할 때에 비해 환자의 임상적 경과를 호전시킬 뿐 아니라 가족의 경제적 부담도 줄일 수 있다. Objective : We evaluated the clinical efficacy of a comprehensive psychiatric rehabilitation of schizophrenia, including family psychoeducation, patient education, social skills training, group psychotherapy, art therapy, and occupational therapy. Method : From September 1993 to February 1995, 173 chronic schizophrenics who met DSM-IV criteria and were discharged from a locked ward were assigned into the psychiatric rehabilitation service group(psychiatric rehabilitation group, n=46) or the customary out-patient service group(out-patient group, n=127) prospectively, but not randomly. Assignment was based on preferences of patients and their relatives, Each subject included in the psychiatric rehabilitation group received twice weekly patient education, social skills training, family psychoeducation, group psychotherapy, art therapy, occupational therapy and maintenance chemotherapy during a 6-month period. Those in the out-patient group received individual supportive psychotherapy and maintenance chemotherapy according to their clinical needs for 10-20 minutes once per week. After entry into the study, all subjects were assessed for the number of readmission, days of hospitalization, and the direct treatment costs through the first and second year of follow-ups. These outcome variables were also compared pre-and post-2 years at the time point of entry into the study. Aftercare chemotherapy on a weekly to monthly basis continued for the remainder of the two year follow-up period. Results : With regard to the mean number of hospital admissions per year, the mean days of hospitalization per year, and the direct treatment costs per year, the psychiatric rehabilitation group had significantly decreased all clinical outcomes 2 years after compared with before receiving psychiatric rehabilitation. But there were no significant differences in the all clinical outcomes between before and after study intake in the out-patient group. For the number of relapse regardless of drug compliance, 4 patients(9%) during first year and 14 patients(30%) during second year were relapsed in the 46 subjects of the psychiatric rehabilitation group. In contrast, 75 patients(59%) during first year and 90 patients (71%) during second year relapsed in the out-patient group. When considering the effect of drug noncompliance to relapse, 4(9%) and 14 patients(30%) were relapsed while on medication respectively during the first and second year in the 46 of the psychiatric rehabilitation group, vs. 27(34%) of 79 patients on medication during the first year and 31(46%) of 68 patients on medication during the second year were relapsed in the out-patient group. Conclusions : These results indicate that the comprehensive psychiatric rehabilitation can be useful therapeutic intervention both to improve the clinical outcomes of schizophrenic patients and to reduce the economical burden of their relatives.

Field experimental study was performed to examine characteristics of nutrient export from paddy rice fields with irrigation practices. Experimental fields with surface-water and ground-water irrigation were monitored and analyzed during rice culture period. The water balance showed that outflow generally balanced the inflow showing that about half (58∼68%) of total outflow was lost by surface drainage. Water and nutrient export are more in surface-water irrigation paddy than in ground-water irrigation paddy. The reasons might be more irrigation water available and easy to use in surface-water irrigation. If irrigation water reduced, it could result in reduction of nutrient export in paddy rice fields, which can save water and protect water quality. However, deviation from conventional standard practices might affect the rice yield and further investigations are necessary.

음향방출과 미세역학적시험법을 이용한 단일섬유강화 에폭시 복합재료의 비파괴적 섬유파단 위치표정 및 계면물성 평가

박종민,공진우,김대식,윤동진 한국비파괴검사학회 2003 한국비파괴검사학회지 Vol.23 No.5

섬유파단은 복합재료의 기계적물성을 규명하는 가장 중요한 현상 중 하나이며, 섬유파단 위치는 기지재료의 물성과 섬유표면 처리에 따라 광학현미경에 의한 방법 뿐만 아니라 음향방출법을 이용하여 확인 및 상호비교 할 수 있다. 두 개의 음향방출 센서를 단일섬유강학 에폭시 복합재료 시편 표면에 부착 시켜 연속적인 섬유파단 신호를 변형률과 측정 시간에 따라 감지하였으며, 계면전단강도는 단일섬유강화 복합재료 시험에서 광학적 방법과 음향방출법을 이용하여 측정하였다. 탄소섬유의 파단 수는 섬유표면을 전기증착으로 처리한 경우가 많았으며, 광학적인 관찰 시에 좀 더 많게 나타났다. 하지만 음향방출법과 광학적 방법에 의한 섬유파단의 위치는 작은 오차범위 내에서 상호 잘 일치하는 결과를 얻을 수 있었다. 음향방출법에 의한 섬유파단 위치표정과 파형분석은 투명, 반투명 및 불투명한 복합재료의 계면물성을 비파괴적으로 측정하기 위한 유용한 방법으로 사료된다. Fiber fracture is one of the dominant failure phenomena affecting the total mechanical performance of the composites. fiber fracture locations were measured through the conventional optical microscope and the nondestructive acoustic emission (AE) technique and then were compared together as a function of the epoxy matrix modulus and the fiber surface treatment by the electrodeposition method (ED). Interfacial shear strength (IFSS) was measured using tensile fragmentation test in combination of AE method. ED treatment of the fiber surface enlarged the number of fiber fracture locations in comparison to the untreated case. The number of fiber fracture events measured by the AE method was less than optically obtained one. However, fiber fracture locations determined by AE detection corresponded with those by optical observation with small errors. The source location of fiber breaks by AE analysis could be a nondestructive, valuable method to measure interfacial shear strength (IFSS) of matrix in non-, semi- and/or transparent polymer composites
