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 purpose of this study is to inspect effects of regular walking and barefoot walking, which is the easiest way for middle-aged women to exercise in daily life, on serotonin, cortisol, epinephrine and norepinephrine in blood and probe the differences of hormonal changes between two groups. Both of two programs were performed three times a week and each program lasted for more than 30 minutes. The group of regular walking was set at 40-60%(HRmax) and the group of walking barefoot was set at level 10-12(RPE). This research is for reducing middle-aged women's stress and helping to promote their health. All the data is processed by using the arithmetical mean and standard deviation and two-way ANOVA is used to verify differences between groups and durations. In case that there is interaction, independent t-test is used for group comparison and dependent t-test is used for duration comparison to inspect details. Degree of hypothesis acceptance is set at p<.05, p<.01, p<.00l. Firstly, the serotonin rate is reduced in both groups after conducting the programs. Significant main effect of serotonin has differences related to durations at F(1.18)=8.281, p=.01 but there's no differences between groups at F(1.18)=.289, p=.597. There is no differences in interaction as well at F(1.18)=.432, p=.520. Secondly, significant main effect of the cortisol rate in both groups after conducting the programs has no differences related to durations at F(1,18)=.292, p=.595 and there's no differences between groups at F(1.18)=.121, p=.732. There is no differences in interaction as well at F(1.18)=.899, p=.356. Thirdly, the result of paired t-test shows that epinephrine rate of the group performing regular walking is reduced more than one of those who walk barefoot at t=2.326, df=9, p=.045 and there is a difference in interaction at F(1.18)=5.815, p=.027. Lastly, the norepinephrine rate of those who take usual walks shows a meaningful difference related to durations at F(1.18)=24.505, p=.00l which is more noticeable than one of the other. However, there is no difference between groups at F(1.18)=.175, p=.680 and there is also no difference in interaction at F(1.18)=.902, p=.355. The result says that both of the programs, regular walking and walking barefoot, don't influence the amount of middle-aged women's stress positively, which is against the previous studies. It is because this research exclude other factors which can influence hormone secretion of middle-aged women such as weather, time, diet and mental state in middle age. It can be deduced that future researches to promote middle-aged women's health and decrease the symptoms of depression should include changes caused by temperature, time to exercise, exercise intensity and subject's psychological state in middle age.

Purpose : To determine normal CT number range of parotid gland by analyzing the change by age increase and the difference among individuals and between both sexes in CT number of normal parotid gland. Materials & Methods : 134 subjects who took the CT scan between the period of Jan. 1996 and Dec. 1997 at Yonsei University, Dental Hospital were selected. Criteria for selection were that the patients must be within the normal range clinically and radiologically, and the entire parotid gland on the axial view must be shown. Among the axial views, the one showing the greatest parotid gland size was selected and its CT number was recorded. Also, CT numbers from both masseter muscle were recorded as its control. Results : There was statistically significant correlation between CT number of right and left of parotid glands and masseter muscles. With the increase of age, there is a significant decrease in the CT number of parotid gland(p<0.05). There was no statistically significant difference in CT number between sexes except the 7th decade and beyond age group of parotid gland(p>0.05). Conclusion : As age increases, CT number of parotid gland has a tendency to decrease, and there is no significant difference in the CT numbers between left and right parotid gland. Therefore in the CT scan of patients suspected of having a salivary gland disease of the parotid gland, to consider normal range of the age-dependent CT numbers of parotid gland and compare the CT numbers of the right and left parotid gland might be useful in diagnosing the disease.(J Korean Oral Maxillofac Radiol 1999;29:451-458)
