PURPOSE: The purpose of this study was to analyze the clinical features and to assess the risk factors in the treatment of small-bowel obstructions. METHODS: This retrospective clinical report was based on the medical records of 67 patients who were treated between Jan. 1992 and Dec. 1999 and who had had a history of abdominal surgery due to cancer. RESULTS: The distribution of primary cancer was as follows: stomach cancer 36 (53.7%), colorectal cancer 25 (37.3%), uterine and ovarian cancer 4 (6.0%), and other cancers 2 (3.0%). The mean interval from the primary operation to the development of a small- bowel obstruction was 27 months. Conservative treatment produced a successful outcome in 36 patients (59.0%), but recurrences of obstruction were noted in 18 of those patients. There were 34 operations in 30 patients. The initial success rate of operative treatment was 80% (24/30), obstructions recurred in 6 patients. The causes of obstructions in the surgically treated patients were adhesion (53.3%) and recurrence of cancer (46.7%). The postoperative complication rate was 44.1%, and the mortality rate was 20.0%. The mean survival time of the patients with benign causes of obstruction was significantly longer than that of the patients with malignant causes of obstruction (46 months vs 11 months). CONCLUSION: In the treatment of such patients, conservative treatment should be considered first. However if conservative treatment fails, surgery should be done without hesitation, especially in patients with no definite evidence of recurrence.

PURPOSE: The purpose of this study was to investigate Korean blue-collar workers' Health-related Quality of Life (HRQoL) and influencing factors in Korean blue-collar workers. METHODS: Participants in this study were 109 Korean blue-collar workers. The survey included health-related, work-related, and psycho-social factors. SF-36 was used to measure HRQoL. The data were analyzed using Pearson's correlation, and hierarchical multiple regression analysis. RESULTS: In the hierarchical linear regression model, when subjects' psycho-social variables were included in the regression model, R2 change was statistically significant. The significant predictors for HRQoL were education level (beta=.26, p=.023), depression (beta=-.38, p<.001), and self-efficacy (beta=.23, p<.001). CONCLUSION: The results of this study indicate that health care providers must have priority to consider psycho-social variables, especially depression and self-efficacy to improve HRQoL in Korean blue-collar workers.

For the purpose of morphologic analysis of human cytomegalovirus (HCMV) antigens reacting with specific monoclonal antibodies, we observed HCMV particles after immunogold staining. HCMV was cultured in human fetal lung fibroblasts to be concentrated by polyethylene glycol 6,000. The HCMV stock was dropped onto Formva-coated grids and was fixed by 2% glutaraldehyde. The grids were reacted with MCMVA57, 93, 135 or with SCMVM1, 6, 14, 49 monoclonal antibodies (MoAbs) follwed by gold (10 nm)-conjugated goat anti-mouse IgG. Then the grids were stained with 2.5% uranyl acetate to be observed under Hitachi 500 or Jeol 1,200 electron microscope. When HCMV was reacted with SCMVM14 and SCMVM49 MoAbs, gold particles were adsorbed to virion envelopes, suggesting that the reactive antigens were envelope proteins. In cases of MCMVA135 and SCMVM6 MoAbs, gold particles were adsorbed to dense bodies as well as to virion envelope. These results, together with the previous results of immunologic and genetic characterization, suggested that the reactive antigens of MCMVA135 and SCMVM6 MoAbs were gB homologue and structural protein, respectively. In case of SCMVM1 MoAb, gold particles were adsorbed to capsids, envelopes, and dense bodies, suggesting that the reactive antigen was structural protein. In case of SCMVM8 MoAb, gold particles were observed between the envelopes and capsids, which space was supposed to be the tegument, suggesting that the reactive antigen was carbohydrate moiety of glycoprotein or its polymer. In cases of MCMVA57 and MCMVA93 MoAbs, gold particles were adsorbed to only dense bodies, suggesting that the reactive antigens were precursors of structural proteins.

PURPOSE: The purpose of this study was to investigate individual and organizational level of cardiovascular disease (CVD) risk factors associated with CVD risk in Korean blue-collar workers working in small sized companies. METHODS: Self-report questionnaires and blood sampling for lipid and glucose were collected from 492 workers in 31 small sized companies in Korea. Multilevel modeling was conducted to estimate effects of related factors at the individual and organizational level. RESULTS: Multilevel regression analysis showed that workers in the workplace having a cafeteria had 1.81 times higher CVD risk after adjusting for factors at the individual level (p =.022). The explanatory power of variables related to organizational level variances in CVD risk was 17.1%. CONCLUSION: The results of this study indicate that differences in the CVD risk were related to organizational factors. It is necessary to consider not only individual factors but also organizational factors when planning a CVD risk reduction program. The factors caused by having cafeteria in the workplace can be reduced by improvement in the CVD-related risk environment, therefore an organizational-level intervention approach should be available to reduce CVD risk of workers in small sized companies in Korea.

Before 1970, mandibular overgrowth was known as main cause of skeletal Class III malocclusion in growing children ; however, recent study reports that many skeletal Class III malocclusion patients also show maxillary deficiency. Since 1972, when Delaire re-accommodated Protraction Head Gear (P.H.G.), many researchers have reported that skeletal Class III discrepancies could be corrected through use of P.H.G., which induces anterior movement of maxilla and change in mandibular growth pattern into infero-posterior direction ; nevertheless, it is very difficult to predict resultant changes of orofacial region. The purpose of this study was to find out what treatment effect P.H.G. has on different study samples. Author divided 51 skeletal Class III malocclusion patients with maxillary deficiency who were treated with P.H.G. into different study groups depending on sex, treatment beginning age, intraoral appliance, and facial growth pattern. By doing so, following results were obtained. 1. Treatment beginning age and Sex Four age groups (5.8 to 8 year-old, 8 to 10 year-old, 10 to 12 year-old, 12 to 14 year-old) were compared, and no significant difference was observed. (p<0.05) There was no significant difference between the sex groups, either. (p<0.05) 2. Intraoral appliance Treatment effects of study groups that used R.P.E.(mean age of 10.2) and Labio-Lingual appliance(mean age of 8.9) were compared. There was no significant difference depending on the type of intraoral appliance that was used. (p<0.05) 3. Facial growth pattern 1) Amounts of SNB and ANB corrections were smaller in clockwise growth pattern group than those in normal or counterclockwise growth pattern group. (p<0.05) 2) Amounts of increase in Wits appraisal and mandibular plane angle were greater in counterclockwise growth pattern group than those in normal or clockwise growth pattern group.(p<0.05) 3)Amounts of increase in articular angle were greater in counter lockwise growth pattern group than those in clockwise growth pattern group. (p<0.05)

We performed a retrospective analysis of the results of surgical treatment of sixteen patient with comminuted fracture of the distal femur from September 1993 to August 1995 and evaluated the efficacy of the angled blade plate as one of the fixation devices used. The fractures were limited to C2 and C3 fracture classifed according to the AO classification. After an average follow-up of 13 months (range, 9 to 24 months), all of the fractures had healed. Postoperatively, the arc of flexion was limited between 90degrees and 125degrees in eight, normal arc in five, and severely restricted arc of joint motion was present unexceptionally in three patients with deep infection. In angular deformity, average 5.8degrees of valgus and 2.4degrees posterior angulation were showed. The functional results by Sanders-Swiontkowski-Rosen-Helfet rating system were showed excellent in 3, good in 7, fair in 3, and poor in 3 cases. The overall results were seen to be excellent to good in ten cases (62.5%) but in twelve patients using the angled blade plate, excellent to good results were showed 10 patients (83.3%). We attribute the favorable results in our series to restoration of the articular surface through the modified extensile approach, sufficient stable fixation using the angled blade plate with conforming to the concept of bridge plate, routinely performing the bone graft for medial buttress and bone healing, and early mobilization of the extremity.

It has been known that head posture may influence directly and/or indirectly the growth and development of craniofacial morphology and can also be influenced by the funtional demand of physiologic activity. It was reported that facial morphology has close relationships with hyoid bone position and head posture. In many previous studies, Natural Head Posture(NHP) was guided, and also it was shown that NHP has high degree of reproducibility. Otherwise, There was few study about the relationship of head posture, with routine cephalometric film which is used for clinical orthodontic purpose. In this study, according to the Wits and ANB of initial cephalometric film which was taken with vertical pendulum as representative of true vertical reference line. We classified the subjects which is comprised of 60 adult female patients into Class 1, II, III (Cl I, II, III)and we tried to find out the correlation of head posture and hyoid bone position according to the classification of malocclusion. As a result of our research, we found the followigs. 1. In comparison of vertical position of hyoid bone relative to the cranial base. the position of hyoid bone of Cl III was lower than that of Cl II. 2. In comparison of anteriorpostes or position of hyoid bone, relative to the cervical column. The position of hyoid bone of Cl III was more anterior than that of a II 3. in comparison of vertical position of hyoid bone relative to mandible. There was no significant correlation aumoug the groups of malocclusion. 4. ANB and Wits showed no significant correlation with hyoid bone position. 5. The relative extension of head, which was noted in Cl II, showed negative with Sum, ANB. 6. In Cl II and Cl III, Post to Ant facial height showed positive correlation with NSL/VER.

Upper canine is important because it protects and maintains the stability of the dental arch and also, joins the anterior with the posterior teeth. The incidence of impaction of upper canine is the second most frequent next to the third molar because it takes a long period of time to develop, and has a complicated path of eruption, and erupts lately. After the age of 10, clinical and radioglaphic examination can be used in revealing the possibility of impaction and efforts should be put to reduce the side effects. To prevent impaction, selective extraction of primary canine at the age of 8 to 9 could be considered and prolonged retention of primary canine in oral cavity should be avoided at this time. Once the impaction is iden, the first stage of the treatment is to localize the lesion by radiographic examination and According to the severity, orthodontic traction or autotransplantation should be considered and comprehensive diagnosis and treatment plan of malocclusion should be established. Generally, labial impaction is due to arch length discrepancy and palatal impaction is due to malposition or morphologic pathosis of lateral incisors rather than arch length discrepancy. In surgical procedure, peridontal problems should be considered and the minimum amount of bone and soft tissue shold be reduced and direct bonding method of many attachment methods should be recommended. Especially in traction of labially impacted canine, it should be guided to erupt through the keratinized zone and proper forced magnitude should be applied. The importance of periodontal condition should always be in mind following the patient education to mintain the good oral hygiene at each stage of treatment. Properly managed impacted canine can provide function and esthetic by proper diagnosis and treatment if extraction of canine is not indicated.
