Background and Purposes: Over the past three decades, numerous studies performed in Korea have reported that job stress is a determinant risk factor for chronic diseases and work disability. Every society has its own culture and occupational climate particular to their organizations, and hence experiences different occupational stress. An occupational stress measurement tool therefore needs to be developed to estimate it objectively. The purpose of this study is to develop and standardize the Korean Occupational Stress Scale (KOSS) which is considered to be unique and specific occupational stressors in Korean employees. Subjects and Methods: Data were obtained from the National Study for Development and Standardization of Occupational Stress (NSDSOS Project: 2002-2004). A total of 12,631 employees from a nationwide sample proportional to the Korean Standard Industrial Classification and the Korean Standard Occupational Classification were administered. The KOSS was developed for 2 years (2002-2004). In the first year, we collected 255 items from the most popular job stress measurement tools such as JCQ, ERI, NIOSH and OSI, and 44 items derived from the a qualitative study (depth interview). Forty-three items of KOSS, in the second year, were retained for use in the final version of the KOSS by using Delphi and factor analysis. Items were scored using conventional 1-2-3-4 Likert scores for the response categories. Results: We developed eight subscales by using factor analysis and validation process: physical environment (3 items), job demand (8 items), insufficient job control (5 items), interpersonal conflict (4 items), job insecurity (6 items), organizational system (7 items), lack of reward (6 items), and occupational climate (4 items). Together they explained 50.0% of total variance. Internal consistency alpha scores were ranged from 0.51 to 0.82. Twenty-four items of the short form of the KOSS (KOSS-SF) were also developed to estimate job stress in the work setting. Because the levels of the subscales of occupational stress were gender dependent, gender-specific standard norms for both the 43-item full version and the 24-item short form using a quartile for the subscales of KOSS were presented. Conclusion: The results of this study suggest that KOSS might be an appropriate measurement scale to estimate occupational stress of Korean employees. Further and more detailed study needs to be conducted to improve the validity of this scale.

목적 : 2002년 말 중국에서 SARS가 발생한 이후 국내에서도 2003년 10월까지 총 3명의 추정환자, 17명의 의심환자가 보고되었다. 향후 추가적인 SARS의 유행이 우려되는 상황에서, 그간의 SARS 환자 진료에 있어서의 실질적인 준비사항, 진료 현황 등에 대한 조사를 통해 문제점을 파악하여, 향후 더 나은 대비가 될 수 있도록 개선점을 제시하고자 하였다. 재료 및 방법 : SARS로 의심되는 환자를 진료 경험이 있는 병원의료진을 대상으로 2003년 10월에 설문조사를 실시하였다. 설문에는 SARS 환자 진료 시의 실질적인 조치, 진료 현황, 병실, 응급실 및 외래에서의 격리 시설과 준비사항, 보건당국의 관리와 지원에 관한 사항을 포함하였다. 결과 : 대상이 되는 22개 병원 중 17개(17/22, 77.2%) 병원이 설문에 응하였다. SARS 환자를 위한 격리실은 응급실, 외래, 일반병실 및 중환자실에서 각각 9개(9/17, 52.9%), 5개(5/17, 29.4%), 15개(15/16, 93.7%), 4개(4/16, 25%) 병원에서 음압처리가 되어있지 않은 일인실 혹은 다인실이 사용되었고, 1개(1/16, 6.3%) 병원에서만 일반병실에서 음압격리실이 운영되었다. 입원환자의 진찰 시 개인보호구의 착용은 거의 모든 의료기관에서 이루어졌다. 보건당국에서 SARS지정병원의 시설 등을 사전에 확인한 곳은 1곳(1/12, 8.3%)이였고, 14개 병원(14/15, 93.3%)에서는 보건당국에 의뢰한 검사결과를 통하 받지 못하였다. 결론 : 의료기관에서 SARS 환자용 격리실뿐만 아니라 기존의 격리실 설비 등이 미흡하였으며, 특히 중환자실 및 외래의 준비가 더욱 부족하였다. 보건당국의 의료기관에 대한 종합적인 지원이 부족하였고, 병원과의 원활한 연계가 잘 이루어지지 않았다. SARS 만이 아닌 격리를 필요로 하는 질환의 적절한 진료를 위해 향후 병원 시설의 정비와 정부차원에서의 보다 구체적이고 실질적인 대책마련이 필요하다. Background : There was an worldwide outbreak of the Severe Acute Respiratory Syndrome (SARS) originated from China in late 2002. During that period three cases of suspected SARS and 17 cases of probable SARS were reported in Korea. With the concerns about the reemergence of SARS-coV transmission, it is important to be prepared for any possibility. So, this study is aimed to analysis the past measures in managing SARS and propose the amendatory plans to improve the preparedness. Materials & Methods : Questionnaires were collected among clinicians with any experience in managing the probable or suspected SARS cases in Oct. 2003. 17 out of 22 hospitals responded to the questionnaire. The contents in the questionnaire were practical activities, personal equipments, response plans, isolation facilities in emergency centers, outpatient clinics, general wards and intensive care units, and relationship with the public health department. Results : The dedicated isolation rooms in emergency centers, outpatient clinics, general wards, and intensive care units were prepared in 9 (9/17, 52.9%), 5 (5/17, 29.4%), 15 (15/16, 93.7%), and 4 (4/16, 25.0%) hospitals, respectively. Except for one hospital that newly made negative pressure room for SARS, single or multi-bed rooms without airborne infection control were used in all the other hospitals. The personal precaution principles were kept quite well in general wards. Before the designation of SARS hospital by the public health department prior evalution to see if the hospital was suitable for managing SARS was conducted in only 1 (1/12, 8.3%) hospital. The results of laboratory diagnosis were reported back in 1 (1/15, 6.6%) hospital. Conclusions : The isolation facilities which can control airborne infection were almost deficient not only for SARS but also for other respiratory transmissible diseases. For the infection control of transmissible diseases including SARS, more investment is needed on medical facilities and comprehensive support from the public health department required.

대구지역 금호강 및 주요 지천 퇴적물의 시·공간적 독성변화

정홍배,문성환,정진애,김재현,박정규,배철한,황인영 한국환경독성학회 2001 환경독성보건학회지 Vol.16 No.4

1. 사전에 선정된 공통 조사 정점들 가운데 KㆍH4(금호대교)이후의 퇴적물 독성이 상부의 것보다 크게 나타났다. 즉, 정점 KH3과 KH4, 그리고 KH4와 KH5 사이에 독성물질 유입원이 있는 것으로 판단되었다. 2. 하천 퇴적물의 독성 수준에 영향을 주고 있는 물질의 종류와 배출원 파악이 필요하였다. 이러한 내용을 향후 계속적 연구 및 조사를 통하여 수행되어야 하는 과제라 사료된다. 3. 퇴적물 시료의 채취 시점에 따라서 동일 정점의 독성 변화가 심하였다. 유해화학물질에 의한 오염 수준과 하천 생태계의 영향을 예측하기 위해서는 하천 퇴적물을 대상으로 경시적으로 독성의 변화를 계속 관측하는 것이 필요하다고 판단되었다. In aqueous ecosystems, the level of toxicity is highly responsive dependant to multiple variables, including rainfall, sunlight, pH, adhesion, etc. Because Korea has particularly distinct wet and dry seasons, the toxicity of pollutants in rivers or streams is dependant on the sampling season and time. In order to examine the effects of rainfall on toxicity, sediment samples were collected from five sites along the Keumho river. It was found that Microlox toxicity levels were generally higher during the dry season than the wet season. It indicated that river pollutants are carried off more quickly by the water during the wet season. As a result, it was recommended that the point sources of pollutants of the Keumho river would be placed between KH3 (Paldalgyo) and KH4 (Keumhogyo), KH4 (Keumhogyo) and KH5 (Dasa).

정순철,김덕수,이재응 중앙대학교 기술과학연구소 2001 기술과학연구소 논문집 Vol.31 No.-

본 연구에서는 660㎾급 풍력발전 시스템용 유도발전기 로터의 강제 응답 해석을 수행하였다. 이를 위하여 유한요소법을 이용한 회전체 시스템의 모드 해석을 수행하였으며, 모드 실험 결과 나타난 고유진동수와 모드 형상의 오차를 줄이기 위하여 유한요소 모델의 구조 변경을 수행하였다. 또한 회전체 시스템의 안정성 해석을 위하여 로터에 작용하는 여러 가지 외력(불평형력, 전자기력등)에 대한 강제 응답 해석을 수행하였다. 그 결과 공진주파수는 운전주파수인 30㎐(1800rpm)의 약 4.5배의 크기에서 발생하였으며, 운전주파수에서의 최대 처짐은 풍력발전기 회전체 시스템의 자중에 의한 정적 처짐과 공극에 비하면 매우 미소하여 거의 무시할 만 하다. 따라서 로터에 작용하는 외력은 시스템의 안정성 큰 영향을 미치지 않는 것이라 결론 지을 수 있다. In this paper, the stability analysis of the rotor system in the wind-power generator was performed by using Finite Element Method. Experimental modal analysis of generator rotor system was performed and the result were used to update the finite element model. The stability analysis of wind-power generator rotor-bearing system was performed through harmonic analysis with all possible external forces including the electromagnetic force, the unbalance force, the torsional force, etc. As a result of stability analysis, the first natural frequency of the bearing-rotor system is 4.5 times as large as operating frequency. The dynamic deflection at operating frequency is quite smaller than static deflection which is also quite smaller than the air-gap. So it can be concluded that the external forces of the rotor have no effect on stability of the rotor-bearing system.

SB군의 접착강도가 II∼IV군에서 SE군에 비해 낮은 값을 나타내었다(p<O.05). SB군은 II∼IV군의 접착강도가 I군에 비해 낮은 값을 보였으나(p<O.05),SE군의 접착강도는 I∼IV군간에 차이를 보이지 않았다(p>O.05). 2. SB군의 질산은 침투 면적이 SE군에 비해 높았으며(p<O.05),SB군과 SE군에서 질산은 침투 면적은 I ∼ IV군간에 차이를 보이지 않았다(p>O.05). 3. 접착강도와 질산은 침투 면적은 SE군의 I, II,III군에서 음의 상관관계를 보였다(p<O.05). The purpose of this study was to evaluate the effects of collagenase and esterase on dentin bond strength and nanoleakage. Resin composites were bonded to occlusal dentin of premolars with Single Bond 2(SB) and Clearfil SE Bond(SE). After the microtensile specimens were prepared and stored in PBS for 24 hours(I) or, PBS(II), collagenase(III), esterase(IV) solution for 4 weeks, the specimens were stained with silver nitrate solution. Microtensile bond strength(μTBS) and silver penetration area were measured and, the results were as follows: 1. For group II, III, and IV, the bond strengths of SB were lower than those of SB(p<0.05). The bond strengths of SB II, III, and IV were lower than that of SB I(p<0.05). There was no difference among the bond strengths of SE I ∼ IV groups(p>0.05). 2. Silver penetration areas of SB were higher than those of SE for all storage groups(p<0.05). In SB and SE groups, there was no significant difference of silver penetration area among I ∼ IV groups(p>0.05). 3. SE I, II, and III showed inverse relationship between the bond strengths and the silver penetration areas(p<0.05).

정명철,김호성,김경철,노지현,고재환,김용봉,권동일 白中央醫療院 2005 仁濟醫學 Vol.26 No.1

Postpartum hemorrhage remains one of the leading causes of maternal deaths. The major causes of postpartum hemorrhage include uterine atony, retained placental fragment, placenta accreta, and lower genital tract lacerations. Conservative treatment is based on administration of uterotonic drugs, vaginal packing, and surgical repair of genital tract lacerations. When bleeding fails to respond to conservative treatment, surgical ligation of uterine vessels or hemostatic hysterectomy is performed. We present a case of postpartum bleeding treated by selective uterine arterial embolization with a brief review of previous literatures of postpartum hemorrhage & uterine arterial embolization.

정영철,이재성 위덕대학교 산업기술연구소 2000 산업기술연구소 논문집 Vol.4 No.1

집적도 향상을 위한 비대칭 n-MOSFET를 대칭형 n-MOSFET와 단일 웨이퍼 상에 0.35 ㎛ CMOS공정으로 동시에 제조하여 그 전기적 특성을 조사하였다. 측정 결과 비대칭 n-MOSFET는 포화 드레인 전류와 선형영역에서의 드레인 소오스간 직렬저항에서는 대칭형 n-MOSFET와 비교하여 열화된 특성을 나타내었으며, 기판전류 특성에서는 비대칭 n-MOSFET의 특성이 대칭형 소자보다 더 나은 특성을 나타내었다. 측정결과를 참조하여 비대칭 n-MOSFET를 회로설계시 용이하게 사용할 수 있도록 모델링 하였다. 이 모델링의 정확성을 MEDICI 시뮬레이션을 통해 확인하였고, 게이트 폭이 넓을 때를 제외하고는 비교적 정확한 값을 나타내었다. Asymmetric and symmetric n-MOSFET's have been fabricated on the same wafer using LOCOS isolation and CMOS process. Saturation drain current characteristics and drain to source series resistance in linear region of asymmetric n-MOSFET's are degraded compared to those of symmetric devices. Substrate current characteristic of asymmetric MOSFET's is better than that of symmetric devices. Asymmetric n-MOSFET's have been modeled using a parasitic resistance connected to symmetric devices, MEDICI simulation has been done for accuracy of this modeling. Simulated curve of reverse as well as forward saturation drain current show good agreement with measured values except for wide gate devices.
