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.

Utilizing the lateral thigh flap as originally described by Se-Min Baek. in 1983, we have treated seven cases of reconstruction involving crushing injuries of the hand. This flap is derived from the third perforator of the deep femoral artery and accompanying wein as per Baek`s method. When a large skin flap was needed such as the case of crushing hand injuries, a lateral thigh flap was more useful than any other flap. From our experiences for reconstruction of crushing hand injuries, the following advantages of this flap are noted: 1. It is possible to obtain a large size of all skin flap. 2. It is relatively thin with a small amount of the subcutaneous fat. 3. The vascular pedicle is long (10㎝ or more), facilitating microvascular anastomosis. 4. The lateral thigh flap can be a sensory flap. 5. It can be accommodated easily to any operating position.

안지오텐신 변환효소 억제제와 안지오텐신 II 수용체 차단제 투여 후 발생한 급성 신부전과 폐부종으로 전원된 선천성 단일신 환자의 치료 1예

Blockers of renin-angiotensin system(RAS) including ACE inhibitor or ARB are one of the most frequently prescribed medications for the treatment of hypertension, heart failure and proteinuria. One of the major side effects of these RAS blockers is the deterioration of renal function, mainly due to a reduction of intraglomerular pressure. Therefore, close monitoring of renal function is recommended when RAS blockers are initially prescribed, especially for the patients with impaired renal function. We report a patient who was transferred to our hospital due to the sudden development of oliguria and dyspnea after treatment for hypertension with ACEi and ARB. She was finally diagnosed as RAS blocker-induced acute renal failure with pulmonary edema complicated on congenital solitary kidney. After hemodialysis and conservative treatment, her renal function was recovered with maintenance of normal urine output. Conclusion:This case highlights the necessity of the functional and structural evaluation of kidney to prevent the serious complication such as acute renal failure before the administration of ACEi and/or ARB.

Background and Objectives : Branchial cleft anomalies are encountered rarely in clinical practice. We reviewed medical records of branchial cleft anomalies according to age and sex distribution, site distribution, characteristics of mass on physical examination, location of mass, preoperative diagnosis, type of branchial cleft cyst and report our experience with 25 cases of branchial cleft anomalies. Materials and Methods : A review of medical records was performed on 25 cases of branchial cleft anomalies diagnosed in pathologic report from January, 1990 to March, 2000. Result : Sex distribution was 11 male and 14 female, age distribution was most common in third decade which was 8 cases(32%). Site distribution was predominant in left side(13 cases), and in physical examination, the characteristics of the mass was nontender(76%), mobile(60%), soft(80%). The lesion site was submandibular area in 2 cases, upper 1/3 portion of sternocleidomastoid muscle(SCM) in 2 cases, middle 1/3 portion of SCM in 20 cases and parotid area in 1 case. The preoperative diagnosis was branchial cleft cyst in 16 cases, cervical lymphadenitis in 3 cases, tuberculous lymphadenitis in 3 cases, branchial cleft fistula in 1 case, dermoid cyst in 1 case and parotid mass in 1 case. Among 25 cases, first branchial cleft cyst was seen in 4 cases, second branchial cleft cyst in 20 cases and second branchial cleft fistula in 1 case. Conclusion : The clinical history of recurrent neck inflammatory episodes in young patients and nontender, mobile, soft neck mass should raise the suspicion of this entity. Investigation using CT scanning in combination with aspiration is useful. Treatment of all branchial cleft anomalies is complete surgical excision because there is lack of spontaneous regression, a high rate of recurrent infection, the possibility of other diagnosis, and rare malignant degeneration. Complete removal without complications depends on a good understanding of regional embryogenesis, a knowledge of the surrounding structure, and awareness of the different anatomical presentation.

이미숙,우준희,진소영,김종원,최창현,김양수,김은옥,김백남,이동화,류지소 대한감염학회 1996 감염 Vol.28 No.3

28세 남자의 후천성 면역 결핍증 환자에서 S. pneumoniae 폐렴이 합병되어 사망한 1예를 경험하여 부검소견과 함께 보고하는 바이다. Pulmonary infections such as Pneumocystis carinii, cytomegalovirus, and tuberculosis are a major cause of morbidity and mortality in patients with human immunodeficiency virus(HIV) infection. Patients with HIV infection are at increased risk for bacterial pneumonia in addition to opportunistic infection. Although in a primary defect, HIV infection is associated with substantial dysfunction of humoral immunity, which predisposes patients to bacterial infections, particularly with encapsulated organisms, such as Streptococcus pneumoniae. We report a case of 28 year-old Korean male with HIV infection who died of respiratory failure due to pneumococcal pneumonia with autopsy findings.

김동한,신용서,전승호,백승화,이갑상 圓光大學校 1992 論文集 Vol.26 No.2

두부의 저장성 향상을 위해 보존료를 첨가하여 저장중 두부의 미생물상과 이화학적 변화를 검토하였다. 보존료 첨가에 의한 두부의 기호도 변화는 큰 차이가 없었으며 부패가 진행될 수록 적정산도와 amino태 및 ammonia태 질소량은 증가하였다. 두부는 acetic acid로 응고시키는 것이 CaCl₂보다 보존료에 의한 저장성 향상에 효과적이어서, acetic acid에 0.05% K-sorbate와 3% NaCl을 혼합첨가한 구는 저장중 이화학적 변화 및 호기성, 혐기성 세균수가 ?? cell/g수준인 점을 고려해 볼 때 30℃에서 48시간까지 저장이 가능하였다. In order to improve the shelf life of Tofu, the effects of preservatives on Tofu were investigated for microbiol and physicochemical changes during its storage. The sensory evaluation was not deteriorated by preservatives (0.05% K-sorbates). According to the progression of spoliage of Tofu, titratable acidity, and amino and ammonia nitrogen contents were increased. The effect of chemical preservatives on the shelf life of Tofu was shown to be stronger in the Tofu by acetic acid than in that by CaCl₂. The presence of 0. 05% K-sorbate and 3% NaCl as a preservative in Tofu by acetic acid extended it's shelf life upto 48 hrs at 30℃.

金龍赫,白東鉉,崔逸壽 (社)韓國火災 ·消防學會 1995 한국화재소방학회논문지 Vol.9 No.2

In this study, the effect of MnO_2 additive on the electrical characteristics of PZN-PSS-PZT Pyroelectric materials for the fire detactor was studies. PZT ceramics used this experimental is 4 composite system [Pb(Zn_1/3 Nb_2/3)O_3 +Pb(Sn_1/3 Sb_2/3)O_3+PbTiO_3+PbZrO_3]. The dielectric constants and dissipation factors decreases as to MnO_2 concentration increases. At the MnO_2 0.5(ωt%), Pyroelectric coefficient shows 8(10^-8C/cm^2℃) which have the highst value among other additive contents. It is found that output voltage maximum peck at MnO_2 0.7(ωt%) is associated with the higher pyroelectric coefficient and Lowered dielectric constant.
