Objective: The authors investigated the frequency of persecutors in persecutory delusions of the psychiatric patients who didn't undergo the arrest or traumatic injury, reside in Gwangju Jeonnam area, and were admitted to the hospital after the 5.18 prodemocracy movement in Gwangju in 1980 upward 10 years. Also this study investigated the frequency of the persecutors before and after the prodemocracy movement and in capital and Gwangju Jeonnam area. Subjects and Methods: Among the 896 patients who were admitted to department of psychiatry, Chosun University Hospital from Jan. 1. 1989 to Dec. 31. 1991, we choosed 144 patients with persecutory delusion who had lived in Gwangju Jeonnam area for 10 years after 5.18 prodemocracy movement as subjects. Persecutors were classified into 7 class: unspecified, family, neighbors, communist or spy, police or army or secret agent, impersonal, others. Results: 1) In our study, the frequency of persecutors was family, unspecified, neighbors, police or army or secret agent, impersonal, others, communist or spy in descending order. As compared to previous studies (1956-2003) including our study about frequency of persecutor at capital area and Gwangju Jeonnam area, and before and after 5.18 prodemocracy movement, 2) At capital area, in the early 1980s, police, family, neighbors, unspecified person was frequent in descending order. In the both of early 1970s, 1990s, neighbors, family, unspecified person, police was frequent in descending order. 3) At Gwangju Jeonnam area, in the early 1970s, family, unspecified person, neighbors, police was frequent in descending order. In the early 1990s, unspecified person and family, neighbors, police was frequent in descending order. 4) The police class was most frequent at capital area in the early 1980s. Conclusions: We suppose that class of persecutor in persecutory delusions of psychiatric patients are changing according to social change, and frequency of police class was decreasing in both of capital and Gwangju, Jeonnam area.

사출성형에 의한 안경 개발

한두희,김복현 호서대학교 반도체제조장비국산화연구센터 2001 반도체장비학술심포지움 Vol.2001 No.-

안경렌즈는 유리를 연마하여 제작하거나 단량체를 세라믹 금형에 넣어 캐스팅공법으로 플라스틱 렌즈를 만드는 것이 일반적인 방법이었다.한편 사출성형에 의한 렌즈 및 안경의 제작은 광학적으로 우수한 재료 및 금형을 개발하지 못하여 국내에서는 시도조차 못하는 형편이다.구미나 유럽의 일부 국가는 PMMA 및 PC를 이용하여 안경 및 안경렌즈를 개발하고 있으며, 이는 공정을 대폭 줄이기 때문에 대량 생산 및 원가절감을 이룩할 수 있다.본 연구에서는 PMMA 및 PC를 이용하여 그동안 성형할 때에 가장 문제가 되었던 오목 렌즈를 제작하기 위한 금본적인 금형 설계의 문제점 해결과 이를 이용한 일체형 안경과 고강도 렌즈의 제작을 고찰하였다.

김호훈,강연호,김성한,박미선,유재연,이복권 대한감염학회 1998 감염 Vol.30 No.5

목적: 국내 설사 환자에게서 분리 동정된 인체 감염 유래 E. coli 균의 혈청군, verocytotoxin 생성능을 구명하여 EHEC 균의 인체 감염 실태를 구명하고, 동물 및 식품 유래 분리균주의 성상과 비교 검토하여 인체 감염 위험성에 대한 기초적 자료를 의학계에 제공하고자 하였다. 방법: EHEC 감염의심 설사 환자 분변 검체로부터 분리된 균주 중 생화확적 성상에 따라 대장균을 분리하였고 이들 균주 중 E. coli O157:H7를 분리하기 위해서는 Dsorbitol 음성균을 선별하였으며, 분리균에 대하여 항혈청으로 응집 시험을 실시하여 혈청군을 구명하였다. 혈청군이 확인된 균주에 대하여 중합효소 연쇄반응 (PCR) 및 역수동라텍스 응집시험 (Reversed Passive Latex Agglutination:RPLA) 으로 verocytotoxin 생성능을 구명하였다. 결과: 장출혈성 대장균 감염 의심설사 환자의 분변검체로부터 25주의 E. coli 균을 분리 동정하였으나 이들 균주는 모두 verocytotoxin을 생성하지 않았다. 분리 동정된 대장균으로부터 확인된 혈청군은 16종으로서 E. coli O1, O6, O8, O15, O20, O25 O26, O28, O29, O44, O86a, O119, O126, O128, O152, 및 O157:H-였으며 E. coli O157:H-혈청형 균주와 E.coli O25 혈청군 균주가 각각 3주씩 분리되어 비교적 높은 분리율을 보였다. 결론: 장출혈성 대장균 감염 의심설사 환자 분변 가검물로부터 총 25주의 E. coli균을 분리 동정하였으나 verocytotoxin을 모두 생산하지 않았다. Background: Since 1982, many countries has reported outbreaks or sporadic cases caused by enterohaemorrhagic Escherichia coli (EHEC) serogroup strains, mainly E. coli O157:H7 type strain. However, systemic investigation about EHEC agents, including E. coli O157:H7, have not been done in Korea. Therefore, we investigated serogroup and verotoxin productivity of E. coli strains isolated from diarrheal patients and estimated risk of human infection in comparison with EHEC strains isolated from cow, pig, and food material in Korea. Methods: Diarrheal patient stool samples were collected and E. coli strains were isolated, according to biochemical characteristics. In order to isolate E. coli O157:H7, D-Sorbitol negative strains were selected. Serogrouping of the E. coli isolates was done by agglutination test. Verocytotoxin productivity was investigated by polymerase chain reaction (PCR) and reversed passive latex agglutination (RPLA). Human infection risk was estimated in comparison with EHEC strains isolated from cow, pig and food materials in Korea. Results: Twenty-five E. coli strains were isolated from the diarrheal patients who were suspected to be infected with EHEC. However, none of these E. coli strains produced verocytotoxin. Out of 25 E. coli isolates, 16 serogroups of E. coli O1, O6, O8, O15, O20, O25, O26, O28, O29, O44, O86a, O119, O126, O128, O152 and 157:H-were found. In each of the E. coli O157:H-and O25 serogroups 3 strains were found. Conclusion: None of 25 E. coli isolated from diarrheal patients who were suspected of EHEC infection produced verocytotoxin producing E. coli have been reported recently in Korea.

한성욱,양득석,김복조 경운대학교 산업기술연구소 2001 産業技術硏究論文誌 Vol.3 No.2(B)

We analysed the soil quality of Taegu and Kyungbuk region according to the 12 different sampling sites. The soil pH of the downtown area near road was lower than that of the other roads, which indicated that this acidification was probably attributed to the acid rain caused by the traffic exhaust gas such as SO_x and NO_x, Acidification was slightly severe in the rice paddy area than in the dry farming area. All concentration of 6 different heavy metal(Cu, As, Pb, Cd, Hg, Cr^+6) and organic contaminants (Cyanide, organic-p, PCBs, phenols) were found to be lower than the standard of soil pollution or not detected. An assessment using the SPI(Soil Pollution Index), which was developed to estimate soil quality, was performed. Each SPC(Soil Pollution Score) were evaluated with the results of the data from this study. The soil quality of most area of Taegu and kyungbuk was determined to Class 1, which indicated that the soil was healthy.
