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.

Objective : This is to report the effectiveness of intraoral distraction osteogenesis for alveolar augmentation in the extremely atrophied alveolar defects and to review the clinical results of the 2 cases. Subjects and Methods : Anterior segmental osteotomy was performed and the trans-oral alveolar distractors(Martin, Germany) were applied in 2 patients with the severe acquired anterior maxillary and mandibular defect. After latent period for 1 week, the osteomized alveolar segments were distracted by 1 ㎜ a day (0.5 ㎜/l turn) for 8 days in case Ⅰ and 0.6 ㎜ a day(0.3 ㎜/l turn) for 10 days in case Ⅱ. The consolidation period was about 8 weeks in each case. Thereafter, 6 titanium threaded implants(Branemark, Restore) were simultaneously installed with removal of distractor. The implants were tested clinically and radiographically. Results : Amounts of acquired alveolar bone were 8 ㎜ in case Ⅰ and 6 ㎜ in case Ⅱ respectively, with the increased width of the ridge crests and soft tissue expansion. Dental implants installated on the augmented alveolar ridges in 8 weeks after distrction were confirmed as in good osseointegration and in good function without any complications. Conclusion : Intraoral distraction osteogenesis can be a good option for alveolar ridge augmentation of the severely atrophied ridges and soft-tissue defects. However, for the better vector control of distracting segments and for anterior esthetics, customized distraction devices could be considered later.

Objetives : In order to provide useful data tbr the further clinical studies with Korean alcohol-dependent patients, enrollment and non-relapse rates were investigated while alcohol-dependent patients wcre followed up for 24 weeks. Methods : The subjects of this study were alcohol-dependent male patients who, for the first time, visited a hospital among 3 groups of hospitals, University Hospital, General Hospital or Mental Hospital, or those who needed to be followed up after discharge from those hospitals. After assigning 12 subjects to each hospital, we investigated enrollment and non-relapse rates while cognitive-behavioral therapy and pharmacotherapy were provided. Results : 1) Forty-eight patients were enrolled and the rate of enrollment was 36.4%. The enrollment rate in the University Hospital group was 52.1%, in the General Hospital group 50.0%. and in the Mental Hospital group 10.4%. 2) In 48 patients, non-relapse rate was 27.1% at 12 week and 18.8% at 24 weeks after starting follow-up. It was 24.4% and 20.0% at 12 and 24 weeks, repectively, in the University Hospital group while the General Hospital group showed 33.3% and 16.7%, respectively, and the Mental Hospital Group showed 20.0% at both 12 and 24 weeks. Conclusion : These results provide important data for further clinical studies of Korean alcohol-dependent patients.

Background : For cultivation of varieties of ginseng, the pure line selection method, which is to select the best among those cultivated in farms for pedigree breeding, replicated yield trials and regional adaptation trials before registering as a new variety, is widely used. Although there are 25 registered varieties of ginseng in Korea, the quality of ginseng is declining together with the amount of harvest being decreased by 15 - 20% due to the heat injuries and diseases from the warming & abnormal climate. Thus, the needs for development of disaster-resistant varieties with better chances of surviving through high temperature, salts and disease are increasing. Therefore, this study is to cultivate disaster-resistant varieties among those selected for their disaster tolerance and salt tolerance through regional adaptation trials. Methods and Results : As a result of examining the growth characteristics of the selected 2 - 5 year old varieties used in the study, among the 5-year old crops, Goryeo 4 and Eumseong 5 showed superior growth in both above and below aerial parts, and among the 4-year old crops, Eumseong 11 and Cheonryang showed superior growth while the growth in the below aerial parts were satisfactory in the order of Cheonryang > Eumseong 10 > Eumseong 11 > Eumseong 9. Among the 3-year old crops, the most superior growth in both above and below aerial parts was observed in Eumseong 14 with the weight of the below aerial part, root diameter and taproot length at 13.8 g, 11.8 ㎝ and 6.2 ㎝ respectively. Among the 2-year old crops, Eumseong 10 showed the most superior growth in both above and below aerial parts. Conclusion : Based on the above results, Goryeo 4 and Eumseong 5 among the 5-year old crops, Eumseong 11 among the 4-year old crops, Eumseong 14 among the 3-year old crops and Eumseon 10 among the 2-year old crops showed the most superior growth among the selected varieties. The growth characteristics of both above and below aerial parts in each year will continuously be monitored.

Properties analyses and treatment characteristics of waste slurry discharged in the wetted flue gas desulfurization process using Mg(OH)₂as a absorbent were investigated. Aeration and coagulation test were carried out to evaluate variation of some factors such as COD, SS, T-N, etc. related to waste slurry treatment. The hydraulic retention time(HRT) and coagulant dosage rate were applied as operating variables in experiment. As experimental results, the reduction effects of COD, SS in aeration test were distinct, due to oxidation of SO₃ and floc, formation of suspended solids. It was also found that the reduction efficiencies of SS and T-P in coagulation test are higher than 90%.

We performed costochondral grafting in mmandibular reconstruction including condyle replacement in 5 patients which have 4 cases of ameloblastoma, 1 case of resorption of left condyle due to osteomyelitis. We harvested the 6 th costochondral cartilage of unaffected side. No specific complications were appeared with unexpected fracture of costochondral junction and infection of operation site, These patients show 30-45mm at month opening, near normal of affected side, near normal or normal of unaffected side at lateral excursion. Postoperative coureses was uneventful with improved cosmetic and functional results. Our report is indicated that the costochondral graft is satisfactory to reconstruct mandibular defect including condyle replacement, especially in growing patients.
