The objective of this study was to investigate the managing realities of EVD and provide a descriptive survey with the attempt to obtain basic data needed for the standardization of EVD management. For that purpose, 220 questionnaire copies were distributed to those nurses who were working with intensive care units at university hospitals, general hospitals, semi-general hospitals in Seoul, Kyongki-de and local areas. Of 158 returned questionnaire copies, 139 were used for analysis. Data were collected during the term of academic seminars of Neurosurgery Nursing Committee and KICA (Korea Intensive Care Association), ranging from Oct. 26 through 27. 2000. The tools utilized a structured questionnaire form consisting of 21 questions on general characteristics, the level of understanding, the level of work performance, standard management guidelines, etc. The data collected were analysed with frequency, percentage, mean vague, chi -square test using the SPSS 10.0 program Findings were revealed, as follows: For managing the prevention of EVD infection, aseptic technique was found to be of the most importance (48.9%),'the technique should be carried out at an operation room'(92.8%), but it was actually performed at intensive care units (over 51.5%). 'The term of antibiotics use should be less than 7 days' (81.8%), while it was actually executed for less than 7 days (49.5%). 'The proper time of quittance from it should be within less than 7 days'(74.1%) but actual quittance was executed only by 51.1%. 'Set exchange is needed' by 54.0% but actual exchange was implemented merely by 28.1%. 'The subject of management should be nurses' was reflected by 40% but actually 52.0% were carried out. As a result of hating analysed the understanding of the management of EVD by general characteristics, a significant difference was found in the necessity for set exchange by hospitals, in the time of quittance of a catheter, and in ablution items by work experience. The result of hating analysed the work performance levels of EVD management by general characteristics revealed that a significant difference in administration facilities of medicine by the classification of hospitals, especially the use of antibiotics and the quitting time of a catheter by the classification of intensive care units, and in the use of antibiotics and ablution items by the standard management guidelines.

UV-TiO_2 반응기를 이용하여 Escherichia coli와 Aspergillus oryzae var. oryzae의 살균효과를 측정하였다. 254㎚에서 최대 14 watt의 자외선 방출량을 내는 램프를 원형 Pyrex유리관 중앙에 설치하였고 TiO_2는 석영관에 박막증착(Thin Film Coating)된 형태와 슬러리 형태로 나누어 회분식으로 살균정도를 측정하였다. E. coli에 대한 살균력은 1.7×10^7 cells/㎖에 대해 5분간 자외선 조사를 하였을 경우 2.0×10^2 cells/㎖으로 감소하였고, 자외선 조사와 함께 슬러리 형태의 TiO_2를 첨가하였을 경우에는 3.4×10 cells/㎖으로, 자외선 조사와 함께 TiO_2가 석영관에 박막증착된 경우에는 7.6×10^2 cells/㎖으로 감소하였다. 한편 위와 같은 조건에 유리관 하부에서 기포를 주입수 11분 동안 자외선을 조사시킨 경우에는 1.3×10^2 cells/㎖으로, 자외선 조사와 함께 슬러리 형태의 TiO_2를 첨가하였을 경우에는 1×102 cells/㎖으로, 자외선 조사와 함께 TiO_2가 박막증착된 경우에는 7.9×10 cells/㎖을 나타내었다. 결국 UV-TiO_2 반응기에 사용되는 TiO_2가 슬러리 형태일 때 최대 살균효과를 나타내었으나 기포가 첨가되었을때는 오히려 살균에 장애를 받는 것으로 나타난 반면 석영관에 박막증착된 경우에는 기포가 첨가되는 것이 살균에 효과적인 것으로 관찰되었다. The killing effect of UV-TiO_2 photocatalytic system on the Escherichia coli DH5-α and Aspergillus oryzae var. oryzae (KCTC 6095) was studied. The UV lamp which emits maximum 14 watts at 254 ㎚ was set on the center of pyrex round glass tube. Two types of TiO_2, one of which is slurry and another which is thin film coated form, were used to determine the killing effect. When UV was irradiated to 1.7×10^5 cells/㎖ of E. coli for 11 min, the living cell number decreased to 4.0×10^0 cells/㎖. The effect of UV system together with slurried TiO_2 was less than 1 cells/㎖, whereas that of UV-coated TiO_2 system decreased to 7.1×10^3 cells/㎖. To study the effect of bubble on the killing of microorganisms, air was bubbled to the bottom of glass tube. When 1.7×10^5 cells/㎖ were exposed to UV for 11 min in combination with air bubble, the living cell number decreased to 1.3×10^2 cells/㎖. In the same condition except the addition of slurried TiO_2, the living cells were 1×10^2 cells/㎖. However, more cells could be killed by the system which consists of UV, coated TiO_2, and air bubble (7.9×10^1 cells/㎖). From these results, it was found that UV-slurried system is the most effective one, but its killing effect is not stimulated by air bubble. However, bubbling was very effective in the UV-coated TiO_2 system.

Dong Min Kim with a pen name of Chukang was born as a first son of the great lanlord Yang-san in 1910. He majored in law at the Myung-chi university in Japan but had great interests and the special affection toward Korean folk dance of Kutgery dance, Buddhist dance, Sanjo dance, Drum, Ajaeng, etc. He also learned the technique of the Korean drum from the late Tae-Heung Kang who was a master in Kayagum. He opened the research institute of Korean folk dance for the first time in Pusan in 1945 and taught our classical dance at elementary, middle and high school. This resulted in the initiative of dance institute which was not Kyeonbon in pursuit of the truly genuine art. He cultivated many disciples with talent, who have been working as famous professors in the universities. Most of disciples have been leading the circles of dance in Pusan as elder presidents in dancing institutes. Therefore Chukang brought a vital power in a stagnated circles of dance and in the cultuural barren area of Pusan. With his special affection was greatly elevated the cultural level of Pusan. He raised the many dancers in Pusan and is a live witness in the modern history of dance in Pusan at the same time.

심세훈,황보영,권영준,정희연,이분희,김용구 대한신경정신의학회 2008 신경정신의학 Vol.47 No.2

Objectives : Several lines of evidence suggest the serotonergic dysfunction involved in the biological susceptibility of suicide. Tryptophan hydroxylase (TPH), the rate-limiting enzyme in the biosynthesis of serotonin, Plays a vital role in serotonin metabolism. In a case-control study, we investigated whether the TPH gene was a susceptible factor for suicidal behavior in depressive patients. Methods : The subjects were 218 depressed patients who attempted suicide and visited emergency rooms in multi-medical centers. One hundred thirty hospitalized non-suicidal depressed patients and the 161 normal controls were matched with the suicidal group. Individuals in all 3 groups were evaluated independently by a Structured Clinical Interview for the purpose of establishing a DSM-IV criteria diagnosis (SCID). The severity of depressive symptoms was evaluated using Hamilton depression rating scale (HDRS). Results : There was no significant difference in genotype distributions and allele frequencies of TPH intron 7 A218C polymorphisms among 3 groups. Furthermore, no significant difference in genotype counts and allele frequencies of the polymorphisms was found among lethal suicidal depressed patients, non-suicidal depressed patients and the normal controls. Conclusion : This study suggests that the A218C polymorphism of the TPH gene is unlikely to have a major effect on the susceptibility of suicidal behaviors in depressive patients.

Jeewon Lee,Young-Sook Kwak,Yoon-Jung Kim,Eun-Ji Kim,E Jin Park,Yunmi Shin,Bun-Hee Lee,So Hee Lee,Hee Yeon Jung,Inseon Lee,Jung Im Hwang,Dongsik Kim,Soyoung Irene Lee 대한신경정신의학회 2019 PSYCHIATRY INVESTIGATION Vol.16 No.3

“Comfort women” are survivors of sexual slavery by the Imperial Japanese Army during World War II, who endured extensive trauma including massive rape and physical torture. While previous studies have been focused on the trauma of the survivors themselves, the effects of the trauma on the offspring has never been evaluated before. In this article, we reviewed the first study on the offspring of former “comfort women” and aimed to detect the evidence of transgenerational transmission of trauma. In-depth psychiatric interviews and the Structured Clinical Interview for DSM-5 Axis I Disorders were conducted with six offspring of former “comfort women.” Among the six participants, five suffered from at least one psychiatric disorder including major depressive disorder, panic disorder, posttraumatic stress disorder, adjustment disorder, insomnia disorder, somatic symptom disorder, and alcohol use disorder. Participants showed similar shame and hyperarousal symptoms as their mothers regarding stimuli related to the “comfort woman” issue. Increased irritability, problems with aggression control, negative worldview, and low self-esteem were evident in the children of mothers with posttraumatic stress disorder. Finding evidence of transgenerational transmission of trauma in offspring of “comfort women” is important. Future studies should include more samples and adopt a more objective method.

Lee, Su Hyun,Moon, Woo Kyung,Cho, Nariya,Chang, Jung Min,Moon, Hyeong-Gon,Han, Wonshik,Noh, Dong-Young,Lee, Jung Chan,Kim, Hee Chan,Lee, Kyoung-Bun,Park, In-Ae by Lippincott Williams Wilkins 2014 Vol. No.

OBJECTIVE: The objective of this study was to compare the quantitative and qualitative shear-wave elastographic (SWE) features of breast cancers with mechanical elasticity and histopathologic characteristics. MATERIALS AND METHODS: This prospective study was conducted with institutional review board approval, and written informed consent was obtained. Shear-wave elastography was performed for 30 invasive breast cancers in 30 women before surgery. The mechanical elasticity of a fresh breast tissue section, correlated with the ultrasound image, was measured using an indentation system. Quantitative (maximum, mean, minimum, and standard deviation of elasticity in kilopascals) and qualitative (color heterogeneity and presence of signal void areas in the mass) SWE features were compared with mechanical elasticity and histopathologic characteristics using the Pearson correlation coefficient and the Wilcoxon signed rank test. RESULTS: Maximum SWE values showed a moderate correlation with maximum mechanical elasticity (r = 0.530, P = 0.003). There were no significant differences between SWE values and mechanical elasticity in histologic grade I or II cancers (P = 0.268). However, SWE values were significantly higher than mechanical elasticity in histologic grade III cancers (P < 0.001), which have low amounts of fibrosis, high tumor cellularity, and intratumoral necrosis. In addition, color heterogeneity was correlated with intratumoral heterogeneity of mechanical elasticity (r = 0.469, P = 0.009). Signal void areas in the masses were present in 43% of breast cancers (13 of 30) and were correlated with dense collagen depositions (n = 11) or intratumoral necrosis (n = 2). CONCLUSIONS: Quantitative and qualitative SWE features reflect both the mechanical elasticity and histopathologic characteristics of breast cancers.

목적: 진행된 대퇴골두 골괴사증 환자에서 무시멘트형 조립식 대퇴주대를 이용한 고관절 치환술의 임상적 및 방사선학적 결과를 평가하였으며, 금속-금속 관절면을 사용한 군과 세라믹-세라믹 관절면을 사용한 군 간, 결과에 차이가 있는지를 확인하고자 하였다. 대상 및 방법: 2001년 1월부터 2004년 12월 까지 대퇴골두 골괴사증으로 조립식 대퇴주대를 이용하여 무시멘트형 고관절 치환술을 시행 받았으며, 5년 이상 추시관찰이 가능하였던 66명(78예)을 대상으로 하였고, 술 후 평균 추시 기간은 평균 77개월(60~122개월) 이었다. 결과: 임상적 평가로 술 전 평균 Harris 고관절 점수는 53점에서 최종 추시 시 88.5점으로 향상되었다. 방사선학적 검사 결과에서 대퇴주대의 안정도는 68예에서 골성고정을 얻었으며, 9예에서 섬유성 안정고정, 1예에서 불안정고정을 나타내었다. 재치환술은 3예에서 시행하였으며, 122개월 간 대퇴 스템의 생존율은 95.7%인 것으로 조사되었다. 결론: 진행된 대퇴골두 골괴사증에서 시행한 조립식 대퇴주대를 이용한 무시멘트형 고관절 전치환술은 5년 이상 추시 결과 금속-금속 관절면을 사용한 군과 세라믹-세라믹 관절면을 사용한군, 모두 만족한 만한 임상적 및 방사선학적 결과를 얻었다. Purpose: The purpose of this study was to evaluate the clinical and radiological outcomes after total hip arthroplasty using the S-ROM modular system for osteonecrosis of the femoral head, and to compare the results between the groups using metal-on-metal articulation and ceramic-on-ceramic articulation. Materials and Methods: Sixty-six patients (78 hips) with osteonecrosis of the femoral head were evaluated after primary total hip arthroplasty between January 2001 and December 2004, using an S-ROM proximal modular femoral stem. The average follow-up was 77 months (range, 60 to 122 months) and all patients were followed for more than five years. Results: The average Harris hip score improved from 53 points to 88.5 points at the final follow-up. At the latest radiologic evaluation, sixty-seven stems had bony ingrowth stability, and 10 stems had stable fibrous ingrowth. However, one stem had diffuse extensive osteolysis and loosening, which was revised at 9 years. Postoperative complications included 4 cases of heterotrophic ossificiation, 1 case of linear fracture after insertion of the femoral stem, 1 case of dislocation, 2 cases of infection, and 1 case of extensive osteolysis and loosening. There were 3 cases of revision and Kaplan-Meier survivorship analysis with revision estimated at a 95.7% chance of survival for the femoral component during 122 months. Conclusion: Our study showed that total hip arthroplasty using the S-ROM modular system with metal-on-metal articulation or ceramic-on-ceramic articulation had favorable clinical and radiological mid- to long-term results.
