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.

Objectives: Workers from a factory was selected to compare 8 standard threshold shift criteria with the Korean diagnostic criteria of noise-induced hearing loss for this cohort study. Methods: From 1990 to 1999, 491 workers at a manufacturing company with complete record of the hearing test covering the range of 0.5~6 kHz for 10 consecutive years were finally selected. Eight standard threshold shift criteria (15 dB once, NIOSH (1972), 10 dB average 3~4 kHz, OSHA STS, AAO-HNS, 15 dB twice, 15 dB 1~4 kHz, OSHA STS twice) along with the Korean standard for diagnosing the noise-induced hearing loss (the average hearing threshold at 0.5, 1 and 2 kHz) were compared to calculate the degree of the threshold shift and the minimum time required to detect the change. Results: Those workers showing at least one positive shift in the ‘once’criteria of NIOSH (1972) were 92.5%; the ‘average’criteria of 10 dB average 3~4 kHz were 35.8%; ‘twice’criteria of 15 dB twice were 44.4%. The duration from the baseline to the year showing the first positive shift was from 3.2 ± 3.1 years (NIOSH, 1972) to 6.0 ± 2.1 years (OSHA STS twice). The percentage of true positive shift ranging from 20.4% (AAO-HNS) to 69.8% (NIOSH, 1972). There were 10 (2%) which met the Korean diagnostic criteria of noise-induced hearing loss. Conclusions: Currently the concept of hearing threshold shift in diagnosing the hearing loss was adopted in Korea thus in this study we determined the validity and the effect of the various hearing threshold shift criteria and showed that NIOSH (1972) criteria was the best of all. In the future, hearing data from various manufacturing workers should be compared to thoroughly evaluate the threshold shift criteria and to establish adequate standard for Korean workers.
