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.

The inhibitory effects were investigated of 254-nm ultraviolet (UV) radiation and lactic acid (LA) treatment on populations of Salmonella (S) enteritidis on eggshell surface. All UV exposures (730, 1,580, 3,000 W/cm²) for 30 sec significantly reduced S enteritidis (P 0.05). UV irradiation with 3,000 μW/cm² almost completely eliminated S enteritidis on inoculated eggshells by 99%. These results suggest that the higher intensity of UV irradiation may be associated with the higher germicidal activity. However, no significant differences were detected between UV exposure times. The treatments of LA at the concentration of 0.1, 0.3 and 0.5 % also specifically decreased the bacterial cell populations (0.91 1.14 log CFU) on the eggshell compared with the control (6.92 log CFU). The treatment of LA at the concentration of 0.5 % had the reaction of a 2.52 log unit storage for 9 days. The combined treatment of UV (3,000 μW/cm²) and LA(0.5%) decreased S enteritidis populations on eggshell by 3.85 log unit, compared wth the control (P 0.05), and its inhibitory effect was stronger with storage time.

Lodging was not appeared in treatment of IBP + Inabenfide compared to 5.0 of the control Resulting to reduciag the lodging, rice yield was increased more with treatment of IBP + Inabenfide, to about 50%, than that of the control

Renal artery aneurysms are rare, in less than 1% consecutive abdominal aortograms. Renal artery aneurysms are bilateral in about 10% of cases. Controversy persists regarding the indications for repair of renal artery aneurysms and optimal method of repair. The authors report a case of renal artery aneurysm with right renal atrophy in a 37-year-old male patient. This patient has no past medical history including hypertension. On physical examination, a pulsatile mass was palpated in left upper abdomen. Preoperative abdominal CT showed right renal atrophy and 8 cm diameter left renal aneurysm. Abdominal aortogram and left renal angiogram showed huge lobulated outpouching contrast collection at the proximal left renal artery without definite neck and diffuse irregularity at the proximal left renal artery. This patient was treated by splenectomy, thrombectomy, aneurysm resection and end to end splenorenal bypass. No remarkable postoperative complication was observed. The patient was doscjarged postoperative 12 days.
