      • 습식 스프레이용 폴리머 모르타르의 성능 평가

        황금식(Hwang Geum-Sic),박찬기(Park Chan-Gi),최강진(Choi Kang-Jin),장계호(Jang Gye-Ho) 한국구조물진단유지관리학회 2006 한국구조물진단학회 학술발표회논문집 Vol.10 No.1

        The major objective of this study was evaluated mechanical properties and chemical resistance of five types of premix type wet process polymer mortar. Also, the effects of two type construction methods were studied. The results of the test of wet process sprayed method were compared with previous hand method. For five type pre mix type polymer mortar, test results show that wet process sprayed method had shown good performance in all of mechanical properties and chemical resistance than hand method. Specially, chemical resistance test results indicate excellent performance.

      • 복합열화상태의 콘크리트 보수를 위한 습식 스프레이용 폴리머 모르타르의 성능

        원종필(Won Jong-Pil),박찬기(Park Chan-Gi),황금식(Hwang Geum-Sic),최강진(Choi Kang-Jin),장계호(Jang Gye-Ho) 한국구조물진단유지관리학회 2005 한국구조물진단학회 학술발표회논문집 Vol.- No.-

        The purpose of this study was to evaluate the performance of wet process sprayed polymer mortar for repair of concrete under combined aging conditions. For wet process sprayed polymer mortar, fly ash and slag effect were investigated with the replacement level of 10-14% of cement weight. Tests of compressive strength, chemical resistance, repeated freezing and thawing were conducted. Test results show that the wet process sprayed polymer mortar, when using fly ash and slag, were effected on the improvement of the compressive strength and durability performance.

        The purpose of this study was to evaluate the performance of wet process sprayed polymer mortar for repair of concrete under combined aging conditions. For wet process sprayed polymer mortar, fly ash and slag effect were investigated with the replacement level of 10 ~ 14% of cement weight. Tests of compressive strength, chemical resistance, repeated freezing and thawing were conducted. Test results show that the wet process sprayed polymer mortar, when using fly ash and slag, were effected on the improvement of the compressive strength and durability performance.

        정신과 입원환자의 공격행동 특성

        전태연,권용실,도규영,장계호 大韓神經精神醫學會 1997 신경정신의학 Vol.36 No.3

        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.
