한태준,조진규 경성대학교 1998 論文集 Vol.19 No.1

The purpose of present study was to investigate the effects of model's demonstration abilities through analysis of the related theories and earlier studies on observational learning. Therefore, the kernel interest of present study was to present the approach methods about acceptance of model's demonstration abilities on the observational learning variables. The present study achieved the following conclusion by analysis of the related theories and the earlier studies on observational learning 1. In the cognitive acceptance situation of the observers about model's demonstration abilities, unskilled modeling is effective as well as excellent modeling. 2. Such observational learning conditions as observation methods are critical variable which can overcome the demonstration abilities of unskilled models. In other words, there are the interaction effects between model's demonstration abilities and observational learning methods conditions. In conclusion, observational learning conditions have to approach as interactive relationship between the cognitive development level of children and the methods of observational learning and model's demonstration abilities.

From this research, the performances of a sludge reduction in the sewage sludge aerobic digestion was experimented by using a sludge pretreatment and membrane bioreactor. The submerged plate membrane was used as the solid-liquid separation membrane . After drawing small amounts of sludge in a bioreactor and then doing the alkaline treatment and ozone treatment, the sludge was sent to back to the reactor. The HRT in the reactor was set as 5 days and the operation in the reactor was carried out at the DO of 1㎎/L on average. After 100 days of operation in the reactor, it was shown that the reduction efficiency of total solids was more than 83%. Most of volatile solids were removed through mineralization, and the considerable portion of the nonvolatile solids was dissolved and then flowed out with the effluent. Only about 16.3% of total solids in the sludge was accmulated in the reactor even without the loss of volatile fraction. Also, by deriving nitrification and denitrification in one reactor simultaneously, more than 90% of nitrogen removal effect was realized and the experiment was run smoothly without fouling of membrane, even in the high concentration of MLSS. Based on this experiment. sludge can be reduced considerably at a low HRT by these two newly suggested approach.

Musgrave變法을 이용한 컵상귀(Constricted Ear)교정

한승규,김태연,정전은 大韓成形外科學會 1990 Archives of Plastic Surgery Vol.17 No.5

The constricted ears are relatively rare and constitute only 10% of all auricular malformations. whereas the minor forms occur in 2% of the general clinical population. the superior portion of the ear, including the helix, scapha, and posterior crus of the antihelix, are bent over and curl downward. The principles of surgical correction are the straightening of the cupping and the coverage of skin. For the correction of consticted ear, there are numerous techniques but they are relatively extensive, involving cartilage or skin flaps, cartilage graft, multi-stage operations. We adopted a modified Musgrave's technique by multiple radiating cartilage incisions and horizontal mattress sutures. 5 cases with constricted ear were treated with this technique and satisfactory aesthetic results were achieved and no significant postoperative complication was developed. The adventages of the modified Musgrave's technique were as followings : 1. The design was simple. 2. The procedure was easy under local anesthesia. 3. The operation time was short. 4. No donor site sacrifice was required.

연구목적 : 1998년 정신건강의 날 기념 한국인 우울증 선별의 날 행사에 자발적으로 참여한 참가자들의 사회인구 통계학적 특성을 분석하고 우울증 선별검사 결과를 평가하기 위하여 본 연구를 시행하였다. 방 법 : 8개 병원에서 얻어진 619명의 자료를 사용하여 선별검사로 밝혀진 우울증의 유병율과 사회인구통계학적 특성 및 응답자의 정신과적 치료를 포함한 과거력 등을 조사하였다. 결 과 : 우울증 척도 점수는 응답자 전체 평균 57.5±13.8로 경도의 우울 증상이 있는 것에 해당되었다. 전체 응답자의 69.5%(430명)가 최소한 경도 이상의 우울 증상을, 43.1%(267명)가 중등도 이상의 우울 증상을, 18.4%(114명)가 고도의 우울 증상을 보였다. 고도의 우울 증상이 있는 응답자의 56.8%와 중등도의 우울 증상이 있는 응답자의 63.9%가 정신과 치료를 받은 적이 전혀 없었다. 나이가 29세 이하인 것과 전임근무 중인 직업상태는 각각 나이가 60세 이상인 것과 직업이 없는 것에 비교하여 우울증으로부터 보호하는 인자임을 시사하였다. 결 론 : '1998 한국인 우울증 선별의 날' 행사를 통하여 많은 우울증 환자들을 선별해낼 수 있었고, 이들의 우울 증상은 몇몇 사회인구통계학적 특성과 유의한 관계가 있음을 확인하였다. 우울증 선별의 날 행사를 통한 우울증에 대한 교육과 우울증 선별검사는 치료받지 못하고 있는 우울증 환자 및 기존의 치료 중인 환자 모두에게 유용한 프로그램임을 알 수 있었다. Objectives : This study was performed to analyze the sociodemographic characteristics of participants in '1998 Korean Depression Screening Day' and to evaluate the results of the screening test. Methods : By using the survey results of 619 volunteers from 8 hospitals, the authors examined the prevalence of depression detected at the screening test and sociodemographic characteristics and the psychiatric treatment history of respondents. The assessment measure was the Zung Self-Rating Depression Scale. Results : The mean depression score of all participants was 57.5±13.8 and it came under mild depression. Of all participants, 69.5%(N=430) had at least mild depressive symptoms, 43.1%(N=267) had at least moderate symptoms, and 18.4%(N=114) had severe symptoms. Never have 56.8% of respondents in the severely depressed range and 63.9% of those in the moderately depressed range had psychiatric treatment. The results suggest that the age group of 29-year-old or younger(relative to 60-year-old or older group) and full-time employment status(relative to unemployment) are protective factors of depression. Conclusions : By '1998 Korean Depression Screening Day', many depressed patients were detected and their depressive symptoms had statistically significant relationships with some sociodemographic characteristics. The results suggest that the education and screening test programs for depressive illness facilitated by Depression Screening Day are useful to the patients regardless of being under current treatment or not.

연구목적: 본 연구는 소아정신과 영역에서 가장 흔한 질환인 주의력결핍 과잉운동장애의 생활학적 표지자로서 지형학적 청각 사건관련전위의 임상적 의의를 알아보기 위하여 시도되었다. 방법: 치료 전 주의력결핍 과잉운동장애 아동 22명과 대조군인 정상 아동 20명을 대상으로 지형학적 청각 사건관련전위 N100과 P300의 잠복기와 전위값을 Global Field Power Measurement 방법을 이용하여 결정하였다. 그리고 주의력결핍 과잉운동장애 아동들을 치료제인 methylphenidate로 8주간 치료한 후 동일한 방법으로 N100과 P300의 잠복기와 전위값을 구한 후, 치료 전 후 그리고 정상대조군 세 군간의 N100과 P300의 잠복기와 전위값을 비교하였다. 결과: N100 잠복기는 치료 전 ADHD군과 정상 대조군, ADHD군 치료 전 후, 치료 후 ADHD군과 정상 대조군 등 세 간에 모두 유의한 차이가 있었다. 치료 전 ADHD군의 N100 전위값은 정상 대조군과 차이가 없었다. P300 잠복기와 전위값은 공히 치료 전 ADHD군과 정상 대조군. ADHD군 치료 전 후 간의 유의한 차이가 있었고, 치료 후 ADHD군과 정상 대조군 간의 차이는 없었다. 결론: 지형학적 청각 사건 관련 전위의 N100 잠복기은 주의력결핍 과잉운동 장애의 상태 표지자로서 의의가 있음을 알 수 있었고, P300 잠복기와 전위값은 상태 표지자일 가능성이 있음을 시사하였다. Objectives : This study was carried out to investigate the clinical availability of topographic auditory event related potential P300 as a biological marker in children with attention deficit hyperactivity disorder(ADHD) Methods : The subjects were composed of children with ADHD(n=22 ; 16 boys, 6 girls; mean age=89.8±17.1months) and normal controls(n=20 ; 12 boys, 8 girls ; mean age=90.6±16.8months). Topographic auditory event related potential was measured by "oddball paradigm",and the latencies and amplitudes of P300 of both groups were determined by Global Field Power Measurement. After 8 weeks treatment with methylphenidate, P300 of ADHD children were also measured. Results : Both P300 latency and amplitude were not different between ADHD children after treatment and normal controls, but significantly different between ADHD children before treatment and normal controls, and between before and after treatment of ADHD children. Conclusion : The results implicate that the latency and amplitude of P300 may be considered as state markers of ADHD.

엄태규,한동엽,손양주 慶星大學校 環境問題硏究所 2002 環境硏報 Vol.12 No.1

Because of its high construction cost of canalization, large municipal wastewater treatment plants, which usually planted and constructed in urban city in korea, is not proper for small town and village especially with low population density. In this study as treatment plant for the small town, a SBR (Sequencing Batch Reactor) using media was selected and operated to remove organic pollutants and nutrients such as nitrogen and phosphorus which can cause eutrofication in lakes and rivers. Laboratory batch experiments were conducted, at 25±2℃, to investigate ways of optimizing the packing ratio of SBR using media. During the experiment period, packing ratio is variated from 5 to 20%. The removal of TCOD about each packing ratio were greater than 90%. Nitrification percentage and rate of Mode 1, 2, 3, 4 were 56, 67, 75, 77% and 1.9, 1.6, 1.3, 1.71 mgNH_4^+ -N/gMLSS/hr. It is to not matter with packing ratio. Denitrification of Mode 1, 2, 3 and 4 were 50, 50, 64 and 75%, denitrification is increased according to increasing packing ratio. Denitrification rate of Mode 1, 2, 3 and 4 were 1.3, 1.0, 1.11 and 1.88 mgNO_3^- -N/gMLSS/hr.
