To measure the degree of work stress and identify factors influencing the stress among OR nurses, a study was implemented for 131 OR nurses working at four university hospitals in Taegu city through self administered questionnaires. Mean score of total work stress of nurses was 3.71, when maximum score was 5. Relatively high degrees of work stress was evident among OR nurses. When the related factors of the stress specified in the questionnaire were grouped into 11 categories, the repondents turned out to feel the highest stress when they were faced with the categories of non-peculiar duty and personal conflict with doctors. The most stressful events were nursing malpractice during surgical operations and damage to OR equipments. The nurses more susceptible to workstress were married with one child, less educated and worked at OR for 3 to 6 years.

길홍량,한헌석,하태선,이경희,박범수 충북대학교 의과대학 충북대학교 의학연구소 1995 忠北醫大學術誌 Vol.5 No.1

가와사끼병은 5세 미만의 영유아에서 호발하는 급성 전신성 혈관염으로 아직 원인이 밝혀지지는 않았으나 감염성질환 또는 자가면역질환 등으로 추정되고 있다. 1967년 일본의 Tomisaku Kawasaki에 의해 처음 보고되었으며 국내에서도 많은 증례보고가 있어왔다. 가와사끼병은 발열, 발진, 안결막 충혈, 사지말단의 변화, 구강과 입술의 변화, 경부 림프선증 등을 특징으로 하며, 치료로는 면역글로블린의 대량 정주요법과 아스피린이 사용되고 있으며 합병증에는 관상동맥류를 비롯한 심혈관질환이 있고 이로 인한 사망율이 1-2%정도인 것으로 보고되고 있다. 이 질환의 재발은 드문 것으로 되어 있고 일본의 한 보고에 의하면 2-3%로 추정된다. 환아는 6세 남아로 14개월 전 처음 가와사끼병으로 진단받고 감마글로블린과 아스피린을 투약 받았고 당시 심혈관질환은 없었으며 본원 내원시에는 발열, 발진, 안결막 충혈, 붉고 갈라진 입술, 좌측 림프선병증과 손, 발의 부종이 있어 가와사끼병의 진단기준을 만족하였다. 환아는 역시 감마글로블린과 아스피린으로 치료받고 증세가 호전되었으며, 심초음파 검사상 관상동맥의 확장이나 관상동맥류의 증거는 없었다. 저자들은 가와사끼병의 재발 1례를 경험하였기에 보고하는 바이다. Kawasaki disease, acute systemic vasculitis, that usually occurs in infant and young children. The etiology is unknown, but is supposed to be infectious disease or autoimmune disease. Kawasaki disease was first reprted by Tomisaku Kawasaki at 1967 and then many cases have been reported in Korea. Kawasaki disease was characterized by fever, rash, conjunctival injection, changes of extremities, changes of oral cavity and lips, lymphadenopathy and has been treated with intravenous gammaglobulin and aspirin. The complications are cardiovascular lesions including coronary aneurysm and coronary thrombosis. Mortality is approximately 1-2%. Recurrence is rare and 2-3% in Japanese reports. A 6-year-old boy presented with the fever, rash, conjunctivitis, red fissured lips, left lymphadenapathy, and hands and feet edema. He had been treated with intravenous gammaglobulin and aspirin for Kawasaki disease 14 months ago. At that time, he didn't have cardiovascular lesion. He was also treated with intravenous gammaglobulin and aspirin at this episode. We didn't detect coronary artery dilatation or coronary aneurysm. So, authors report a case of recurrent Kawasaki disease.

In recent years, gonorrhea has been pandemic and remains one of the most common STDs in the world, especially in developing countries. For the detection of a more effective therapeutic regimen and assessing the prevalence of Penicillinase Producing Neisseria gonorrhoeae(PPNG), we have been trying to study the patients who have visited the Venereal Disease Clinic of Choong-Ku Public Health Center in Seoul since 1980 by menas of the chromogenic cephalosporin method. In 1998, 93 strians of N. genorrhoeae were isolated, among which 60(64.5%) were PPNG. The prevalence of PPNG in Seoul, which had been decreased to 39% in 1996 after a peak of 74.3% in 1993, is increased to 64.5% in 1998.

개인의의 개방병원 참여에 대한 의견

김석범,권굉보,강복수,김기홍 한국의료QA학회 1998 한국의료질향상학회지 Vol.5 No.1

A mailed survey with structured questionnaire was conducted to study the demand of private physicians who were operating their own clinics in the community to be a attending physician at the general hospital. The responding proportion was 21.6 percent of the 960 private physicians. A total of 207 responders : 65.2 percent wanted to be a attending physician. In particular, the physicians who were male, young, surgeon and teaching hospital careered after specialist were more highly motivated. The major activities what they wanted as a attending physician were medical care for the admission patients. They responded that the hospital charges for the medical services and the responsibility of malpractice issues should be fairly shared by attending physician and hospital according to their contributions. There is growing consensus that the need of attending physician at the general hospital will become wide spread, but little organizational preparation to assure the quality of medical care of attending physicians including training of resident physicians and students. In addition, the effective reimbursement system should be develop to compensate appropriately according to the medical achievement of the attending physicians.

Pumpless dispensing of a droplet by breaking up a liquid bridge formed by electric induction

Hong, Jin Seok,Lee, Beom Seok,Moon, Dustin,Lee, Jeong–,Gun,Kang, In Seok WILEY-VCH Verlag 2010 Electrophoresis Vol.31 No.8

<P>Dispensing uniform pico-to-nanoliter droplets has become one of essential components in various application fields from high-throughput bio-analysis to printing. In this study, a new method is suggested and demonstrated for dispensing a droplet on the top plate with an inverted geometry by using electric field. The process of dispensing droplets consists of two stages: (i) formation of liquid bridge by moving up the charged fluid mass using the electrostatic force between the charges on the fluid mass and the induced charges on the substrate and (ii) its break-up by the motion of the top plate. Different from conventional electrohydrodynamic methods, electric induction enables the droplets to be dispensed on various surfaces including non-conducting substrate. The use of capillarity with an inverted geometry removes the need of external pumps or elaborates control for constant flow feed. The droplet diameter has been characterized as a function of the nozzle-to-plate distance and the plate moving velocity. The robustness of the present method is shown in terms of nozzle length and applied voltage. Finally, its practical applicability is confirmed by rendering a 19 by 24 array of highly uniform droplets with only 1.8% size variation without use of any active feedback control.</P>

Is Restoration of Hip Center Mandatory for Total Hip Arthroplasty of Protrusio Acetabuli?

Beom-Seok Lee,Hong Seok Kim,O Sang Kwon,Young-Kyun Lee,Yong-Chan Ha,구경회 대한고관절학회 2022 Hip and Pelvis Vol.34 No.2

Purpose: While initial fixation using a press-fit of the acetabular cup is critical for the durability of the component, restoration of the hip center is regarded as an attributable factor for implant survival and successful outcome. In protrusio acetabuli (PA), obtaining both restoration of the hip center and the press-fit of the acetabular cup simultaneously might be difficult during total hip arthroplasty (THA). We tested the hypothesis that use of a medialized cup, if press-fitted, will not result in compromise of the implant stability and outcome after cementless THA of PA. Materials and Methods: A total of 26 cementless THAs of 22 patients with PA were reviewed. During THA, press-fit of the cup was prioritized rather than hip center restoration. A press-fit was obtained in 24 hips. A pressfit could not be obtained in the two remaining hips; therefore, reinforcement acetabular components were used. Restoration of the hip center was achieved in 17 cups; 15 primary cups and two reinforcement components; it was medialized in nine cups. Implant stability and modified Harris hip score (mHHS) between the two groups were compared at a mean follow-up of 5.1 years (range, 2-16 years). Results: Twenty-six cups; 17 restored cups and nine medialized press-fitted cups, remained stable at the latest follow-up. A similar final mHHS was observed between the restored group and the medialized group (83.6±12.1 vs 83.8±10.4, P=0.786). Conclusion: Implant stability and favorable results were obtained by press-fitted cups, irrespective of hip center restoration. THA in PA patients showed promising clinical and radiological results.

Development and Application of CFT without Fire Protection using High Performance Steel and Concrete

Hong, Seok-Beom,Kim, Woo-Jae,Park, Hee-Gon The Korean Institute of Building Construction 2013 한국건축시공학회지 Vol.13 No.3

Concrete filled tube (CFT) columns, which consist of a steel tube filled with concrete, combine the benefits of the two materials. The steel tube provides a confining pressure to the concrete, while the local buckling of steel plate can be prevented by the concrete core. CFT columns also have a high fire resistance due to the heat storage effect of concrete under fire. For this reason, it is possible to develop CFT columns without fire protection measures. CFT columns without fire protection have many advantages, including quality control, cost reduction, better space efficiency and a shorter construction period. Due to these advantages, studies on the development of CFT columns without fire protection measures have been performed. However, CFT columns lose their bearing capacity under fire because the steel tube is exposed to the outside. As a result, the structure is collapsed, causing significant damage. In this research, we made a CFT column using high strength concrete (100 MPa) and high strength steel (800 MPa). We use steel fiber and nylon fiber with concrete to provide fire resistance. We perform the fresh concrete experiment and investigate the fire resistance of the CFT column (${\Box}400{\times}400{\times}15{\times}3000mm$) under loading. To investigate the effect of steel fiber on increasing fire resistance, we compare the fire resistance time according to the steel fiber. Through the test, it was found that the CFT specimen with steel fiber had better fire resistance performance than other cases.
