전태연,도규영,정종현,권용실,김석범 大韓神經精神醫學會 1998 신경정신의학 Vol.37 No.5

목 적 : 혈청 콜레스테롤 농도와 자살 등의 공격행동간의 연관성에 관한 여러 연구가 있었으나 일치된 결과를 보이고 있지 못하다. 이에 저자들은 다양한 진단의 정신과 입원 환자들 중 공격행동을 보인 환자의 콜레스테롤 농도를 정상 한국 성인에서의 혈청 총 콜레스테롤의 성별, 연령별 평균 및 표준편차와 percentile분포에 맞추어 공격행동 및 자살시도와 혈청 콜레스테롤 농도간의 연관성을 알아보기 위하여 본 연구를 시행하였다. 방 법 : 본 연구는 1994년 1월 1일부터 1995년 6월 31일까지 18개월간 카톨릭대학교 의정부성모병원 정신과 병동에 입원하였던 환자 중 콜레스테롤 농도를 얻을 수 있었던 127명을 대상으로 하였다. 대상 환자는 공격행동의 유무에 따라 공격군과 비공격군으로 분류하여 공격군 35명과 비공격군 92명의 자료를 얻었으며, 공격군은 Overt Aggression Scale을 사용하여 평가하였다. 측정된 각 환자의 콜레스테롤 농도는 정상 한국 성인에서의 혈청 총 콜레스테롤의 성별, 연령별 평균 및 표준편차와 percentile분포에 맞추어 4개의 군으로 나눈 후 공격행동 발생비율, 자살시도간의 차이를 알아보았다. 또한 공격행동을 보인 군에서도 각 콜레스테롤군 간의 총 공격 점수를 비교하였다. 결 과 : 1) 각 콜레스테롤군 간의 공격행동 발생비율에는 유의한 차이가 없었다. 2) 공격군에서 각 콜레스테롤군 간의 총 공격 점수는 유의한 차이를 보이지 않았다. 3) 각 콜레스테롤군 간의 자살시도 빈도는 유의한 차이가 없었다. 결 론 : 정신과 입원 환자의 혈청 콜레스테롤 농도를 정상 한국 성인에서의 혈청 총 콜레스테롤의 성별, 연령별 평균 및 표준편차와 percentile분포에 맞추었을 때 혈청 콜레스테롤 농도와 공격행동 및 자살시도에 유의한 연관이 없었다. Objectives : An association between serum cholesterol concentration and violent behavior has been suggested, but has not been consistently demonstrated. This study was conducted in order to evaluate the relation between serum cholesterol concentration and violent behavior in psychiatric inpatients who had been admitted at Uijongbu St. Mary's Hospital, the Catholic University of Korea from January 1994 to June 1995. Methods : We divided the 127 subjects into violent(35 subjects) and non-violent group(95 subjects). According to the percentile distribution of serum total cholesterol in healthy Korean adults, the subjects were classified into four subgroups : Group 1, subjects Whose cholesterol concentrations were below 26% of percentile distribution, Group 2, from 26% to 50%, Group 3, 51% to 75% and Group 4, above 75%. In the four cholesterol subgroups, the authors examined the incidence of violent behaviors and suicidal attempts. Within the violent group, total aggression score of four cholesterol subgroups was compared. Results : 1) Among the four cholesterol subgroups, there were no significant differences in the violent behavior. 2) Within the violent groups, total violent score of the four cholesterol subgroups showed no significant difference. 3) Among the four cholesterol subgroups, there were no significant differences in suicidal attempt. Conclusion : When the serum cholesterol concentrations of psychiatric inpatient applied to the percentile distribution of serum total cholesterol in healthy Korean adult, no association was found between serum cholesterol concentration and violent behavior and suicide attempt.

漢陽 原形景觀의 二元的 重層性 考察

홍윤순,이규목 서울시립대학교 부설 서울학연구소 2002 서울학연구 Vol.- No.19

This study attempts to interpret the immanent dualism of the archetype landscape of Hanyang based on Yin-Yang's dualistic structure. The north eastern Asian dualism being different from western analytical dualism, it shows the following relational attitudes. First, others are recognized as essentially pre-requisite for its own existence not as antagonistic. Second, Yin-yang represents the complementarity. Third, Yin-yang is not independent but inter-related elements. Forth, Yin-yang shows not static but dynamic characteristics. Fifth, the concept of Yin-yang is considered as both extreme points of Taegeuk that has holistic characteristics. In this study, the compound dualistic relationships of the archetype landscape of Hanyang are analyzed according to the aspects of physical environment, activity, and meaning. The contents are as follows; mountain and city boundary represent the dualistic relationships of nature and city. In detail, dualism of settlement for living such as outside the fortress and inside the fortress is also found. The dualism showed through land use and arrangement of main facilities is that Jongmyo and Sajik were arranged along the dualistic characteristics since the establishment of Chosun Dynasty and type of settlement was divided into Northern-village and Southern-village. In addition, the meaning of north-south and east-west roads was dualized and main road and sub-road showed the complementary characteristics in the linear surroundings. In the aspects of facilities, dualistic relationships between palace, fortress and gate, Sadaebu house, Hangrang, and general buildings showed dualism of meaning, size, settlement and types. These dualistic characteristics projected from the aspects of physical environment, meaning and activity reflect the detailed characteristics of Yin-yang. It was found that the concept of Yin-yang is compound from architectural environment to urban unit scale. It is implied that the cities in Korea were formed on the basis of inter-relationships and ultimately represented the unification and reconciliation.

형광들을 점등시키는 안정기의 역할은 형광등과 같이 부저항특성을 갖는 방전등에 과전류가 유입되어, 파괴되지 않도록 일정전압 및 전류를 유지시켜주는 것이다. 최근 사용되고 있는 전자식안정기는 25-30KHz의 주파수를 사용, 캐패시터에 의한 안정화전류를 유도하고 있다. 그러나 전자식안정기는 고주파를 사용하는 관계로 제품의 품질보증을 위한 제반 규정이 까다로워 생산자는 개개의 안정기를 실제 형광등을 사용하여 특성검사를 하고 있다. 본 논문에서는 전자식안정기 특성검사의 효율성을 제고하기 위해 실제 형광등과 동일한 특성을 갖는 의사부하의 설계에 관하여 연구하였다. 초기의 과도 조건을 고려하지 않는 정전압 특성을 갖는 의사부하를 설계하여 실험한 결과 제한된 조건하에서 사용될 수 있음을 확인하였다. The electronic ballast has a role of taking a stable current of fluorescent lamp, which has a characteristics of negative resistance. Recently, it has been designed and operated on using the regulated constant current with capacitor and high frequency of 25 to 30KHz. But a fabricated electronic ballast in an assembly line was difficult to test, because it used a high frequency and needed strict provisions. And then manufacturer is now testing each ballast with a real fluorescent lamp. In this paper, we studied that real lamp can be replaced by a dummy load with the same characteristics.

Microsurgery and myocutaneous flap have been developed recently for wide employment in plastic and reconstructive surgery. Therefore, the delay procedure has been declined in its use recently, because it has many difficult problems. If the flap is longer and larger, it should be delayed for complete survival, but delay requires considerable time. Therefore, as a substitute for delay, vascular anastomosis in the distal part of a flap will theoretically give the same effect. In this study, we investigated the importance of arterial inflow in the distal side of a flap in rats. The experiment was done in 3 different groups according to the design of flaps and in each group 3 subgroups were made. In A flap, the superficial epigastric artery was preserved or anastomosis. In V flap. the superficial epigastric vein was preserved or anastomosis. In C flap, as a control flap, both artery and vein were severed. In result, A flaps in all 3 groups were completely survived. Both V and C flaps in all 3 groups were showed distal necrosis. But C flaps were showed more necrosis than V flaps. In conclusion, we suggest the possibility that a large flap may be transposed in one stage with vascular anastomosis in the distal part-preferably artery and vein, or artery only.

저자들은 1994년 1월 1일부터 1995년 6월 31일까지 가톨릭대학교 의과대학 의정부성모병원 정신과에 입원했던 환자들 중세서 공격행동을 보인 환자(공격군) 72명과 공격행동이 없었던 환자(비공격군) 215명의 임상적 특성에 관한 조사를 하여 다음과 같은 결과를 얻었다. 1) 공격행동을 보인 환자는 72명으로 전체 조사 환자의 25.1%이었다. 2) 성별, 연령, 종교, 결혼 상태와 정신과 질환의 가족력 등에 따른 공격행동의 발생비율의 차이는 유의하지 않았다. 3) 교육 정도와 직업에 따른 공격군의 비육에 유의한 차이가 있었다(p<.05). 4) 진단별로는 공격군에서 조증, 기질성 정신장애, 정신분열증의 빈도가 높았으나 진단에 따른 의미 있는 차이는 없었다. 5) 공격행동의 기왕력은 공격군에서 더 많았고 비공격군과 비교시 의미 있는 차이를 보였으며(p<.001), 입원 형태는 공격군에서 타의 입원의 빈도가 유의하게 높았다(p<.005). 7) 입원시 정신병리는 초조-흥분과 적대감-의심에서 공격군의 빈도가 높았으며 정신병리에 따른 의미 있는 차이를 보였다(p<.001). 8) 총 재원 일수는 공격군에서 평균 59.3일이었고 비공격군이 평균 38.4일로 유의한 차이를 보였다(p<.001). 9) 공격행동의 유형은 말로한 경우가 가장 많았고 물건을 대상으로한 행동, 타인을 대상으로 하는 행동의 순으로 나타났다. 10) 공격행동 직전 행동 특징은 활동증가, 시끄러움, 욕설, 분노, 적대적이었던 경우가 가장 많았다. 11) 공격행동은 정오에서 오후 6시 사이, 휴식시간에 가장 많이 나타났다. 12) 입원 후 1주일 이내에 공격행동의 62.3%가 나타났다. 13) 총공격 점수에 의미 있게 영향을 주었던 변인들로는 종교(p<.05), 교육 정도(p<.05), 직업(p<.05), 입원형태(p<.005), 진단(p<.001), 입원시 정신 병리(p<.001), 공격행동의 기왕력(p<.001) 등으로 나타났다. To evaluate the characteristics of violent behavior of psychiatric inpatients the authors reviewed clinical records of psychiatric patients who had admitted at UiJong Bu St. Mary's Hospital from January 1994 to June 1995. We divided the 287 subjects into violent and nonviolent group according to the presence of violent behaviors in psychiatric ward. We assessed demographic variables, clinical characteristics and violent behaviors using Overt Aggression Scale and compared these variables of violent group with nonviolent group. The results were as follows : 1) The number of violent patients was 72(25.1% of the total). 2) In terms of demographic variables, the differences between two groups in education and occupation were significant(p<.05). 3) In psychiatric diagnoses, violent group were more likely to have mania, schizophrenia and organic mental disorder in sequence but there were no differences between violent and nonviolent group. 4) The history of violent behavior was greater in violent group(p<.001) and the mode of admission was significantly different between two groups(p<.005). 5) In cluster of psychopathology on admission, more frequently found clusters of psychopathology in violent group were agitation-excitement and hostile- suspiciousness and there were significant differences between two groups(p<.001). 6) The length of stay in violent group(59.3 days)was significantly longer than nonviolent group(38.4 days)(p<.001). 7) The types of violent behavior were verbal aggression, physical aggression against objects and physical aggression against other people in frequency sequence. 8) The most frequent type of behavioral clue before violent behavior was hyperactive, loud, verbally abusive, angry, hostile(68.1%). 9) Most of violent behaviors were presented between midday and 6 pm. in resting time. 10) 62.3% of total violent behaviors were occurred within first week following admission. 11) The variables which showed significant effects on total aggression score were religion, educational status, occupation, mode of admission, psychiatric diagnosis, psychopathology on admission and history of violent behavior before admission. In summary, these results showed similar trends compared to previous studies on characteristics of psychiatric inpatients. And we found that more important predictors of violent behavior in practice were likely to be history of violent behavior, psychopathology on admission and behavioral cue before violent behavior.
