OBJECTIVES: To compare eating behavior according to the shift work and to find the factors associated with the abnormal eating behavior in university hospital's nurses. METHODS: For this assessment, a cross-sectional study was conducted with 300 university hospital's nurses. Nurses were questioned with self-reported questionnaire forms. After excluding cases with incomplete data, 276 cases are enrolled in the study. To find the factors associated with the abnormal eating behavior, we conducted multiple logistic regression analysis. RESULTS: The proportions of shift work nurses were 63.77%(176 cases). The proportions of abnormal eating behavior among shift work nurses were 22.73%(40 cases), but only 6.00%(6 cases) among non-shift work nurses had the abnormal eating behavior. Considering the shift work period, the proportions of abnormal eating behavior were 31.25%, 22.92% and 17.50% in case of shift work period were less than 1 year, 1~3 years and more than 3 years, respectively. The abnormal eating behavior was associated with having shift work, doing exercise, more weekly working hours, being on a diet and having perception of overweight. But age and body mass index were not influenced the abnormal eating behavior. CONCLUSIONS: In this study, we found that the factors associated with the abnormal eating behavior are the shift work, exercise, weekly working hours, perception of overweight and diet.

In this study, we examined chewing frequency, eating rates, and food consumption volume according to the body mass index of male and female college students. Twenty-five male college students were divided into a normal weight male group (<23 body mass index, n=14) and an obese male group (> or =23 body mass index, n=11). Twenty-five female college students were divided into a normal weight female group (<23 body mass index, n=21) and an obese female group (> or =23 body mass index, n=4). Subjects were provided with abundant fried rice and allowed to consume it at their own pace. Chewing frequency, total mealtime, rate of eating, consumption volume, calorie intake, and the amount of one bite were measured. There were no significant differences in chewing frequency, total mealtime, rate of eating, consumption volume, calorie intake, and the amount of one bite between the normal and obese male groups. There were also no significant differences in chewing frequency, consumption volume, calorie intake, and the amount of one bite between the normal and obese female groups. However, the obese female group had a significantly shorter mealtime and significantly higher eating rate compared with the normal group. Thus, our study suggests that females who eat a meal for a longer time may reduce their food intake, consequently inducing body weight loss.

BACKGROUND: The esthetic and functional outcomes of periorbital defect reconstruction are very important because of the complex anatomy and specialized functions of this region. The orbicularis oculi myocutaneous (OOMC) flap is useful for the reconstruction of periorbital defects. But, according to the location and depth of the defects, the reconstruction using OMC flaps with various techniques is rare. The authors have used various kinds of OOMC flaps in various situations and we present an analysis of our experiences. METHODS: From November 2001 to July 2017, we used 36 OOMC flaps to reconstruct 30 periorbital defects in 25 patients. We analyzed the cause of the defect, its location, the type of concomitant surgery, the method of flap movement, and complications. RESULTS: Of the 30 defects, basal cell carcinoma was the most common cause, accounting for 20 cases. When the used OOMC flap was classified according to the location of the defects, the switch flap was used in nine cases among 15 defects of lower eyelid, and the V-Y advancement flap was mainly used for other parts. As surgical methods according to the depth of defect were classified, all cases involving the tarsal plate were reconstructed with a composite graft. In case of skin and muscles, they were reconstructed only with OOMC flap or with full-thickness skin graft. CONCLUSION: The OOMC flap provides good skin quality that is very similar to that of the defect tissue. Depending on the location and depth of the defect, the OOMC flap may be used properly in a variety of ways to achieve good results.

When in need of medical treatment, Korean citizens have a choice of practitioners of western medicine (WM) or Traditional Korean Medicine (TKM). However, the two branches frequently conflict with one another, particularly with regard to mental disorders. This study was designed to compare the utilization of WM and TKM, focusing on child/adolescent patients with mental disorders. We analyzed F-code (Mental and behavioral disorders) claims from the Korean Health Insurance Review and Assessment Service, including data from 0-18-year-old patients from 2010 to 2012. Slightly more men than women utilized WM, while TKM use was almost evenly balanced. WM claims increased with advancing age, whereas utilization of TKM was common for the 0-6 age group. In WM and TKM, the total number of claims relying on the National Health Insurance Service (NHIS) was 331,154 (92.78%) and 73,282 (97.85%), respectively, and the number of claims relying on medical aid was 25,753 (7.22%) and 1,610 (2.15%), respectively. The most frequent F-coded claim in WM was F90 (Hyperkinetic disorders), with 64,088 claims (17.96%), and that in TKM was F45 (Somatoform disorders), with 28,852 claims (38.52%). The prevalence of a single disorder without comorbidities was 168,764 (47.29%) in WM and 52,615 (70.25%) in TKM. From these data, we conclude that WM takes prevalence over TKM in cases of attention deficit/hyperactivity disorder (ADHD), as well as in psychological problems such as depression and anxiety. On the other hand, patients utilizing TKM more commonly present with physical health problems including somatoform problems, sleep, and eating disorders.

Four strains of fowl adenovirus (FAdV) were isolated from 4 flocks of broiler or layer chickens affected by hydropericardium syndrome in Korea. These FAdVs were classified as serotype 4 by restriction fragment length polymorphism patterns of hexon genes and whole genomes. The virus exhibited cytopathic effects consisting of rounding, ballooning and clustering in primary chicken embryo liver cell cultures. In transmission electron microscopy, virus particles in hexagonal shape aggregated exclusively in the nuclei of hepatocytes of the chickens as the typical appearances in adenovirus infections. Buoyant density of the virus in cesium chloride (CsCl) was 1.34 g/mL. The virus was stable to chloroform, ether, 50~70% ethanol, acidic condition at pH 3, 0.25% trypsin (1 : 250), heat at 50degrees C for 30 min, but labile to 100% ethanol, heat at 52~60degrees C for 30 min, 1 M MgCl2 at 50degrees C for 1 h, 1 : 2,000 formalin (37%). All of the physicochemical properties pertained to the characteristics of adenoviruses. Eight viral polypeptides were determined in CsCl-purified virus by sodium dodecyl sulfate-polyacrylamide gel electrophoresis.

PURPOSE: Treatment of impotence has advanced considerably by an orally active, effective and well-tolerated drug, sildenafil citrate. However, Sildenafil citrate is not so effective for the treatment of severe organic impotence patients. Intracavernosal injection of vasoactive substance is still the most effective therapy for those patients but side effects, e.g. pain, priapism, require a more comfortable therapy. We performed this study to assess the feasibility of sildenafil citrate as a new intracavernosal agent. MATERIALS AND METHODS: In New Zealand white male rabbits (n=11), relaxations of precontracted cavernosal smooth muscle strips were studied after administration of sildenafil citrate, acetylcholine and sodium nitroprusside (SNP), respectively. In separate in vivo experiment, changes of intracavernosal pressure (ICP), duration of increased ICP and changes of systemic arterial blood pressure after retrograde selective internal pudendal arterial administration of four separate doses (0.1 mg, n=5; 0.3 mg, n=6; 0.5 mg, n=7; 1.0 mg, n=7) of sildenafil citrate were monitored in adult male cats (n=25). RESULTS: Acetylcholine, SNP and sildenafil citrate effectively relaxed the precontracted strips in a dose-dependent manner (3x10 8-3x10 3 M), respectively. Maximal relaxation of strips to acetylcholine, SNP and sildenafil citrate were 50.11%, 98.65%, and 68.32%, respectively.
