Intramuscular lipomas are benign soft-tissue mesenchymal tumors which rarely occur in the region of the head. These tumors present as slow-growing, generally painless masses and are easily misdiagnosed initially as epidermal inclusion cysts. We describe a 44-year-old woman who presented with an intramuscular lipoma of the frontalis muscle.

We report one case in which delayed enhanced computerized tomography (1.5 hr. later) contributed in detecting a dysplastic kidney with a single vaginal ectopic ureter that had been nonfunctioning on excretory urography and had not been detected by other diagnostic methods.

The digital dust indicator (Sibata P-5), one of the direct-reading instruments was evaluated for the respirable dust in the underground coal mine environments. As a reference, respirable dust was determined using three cyclones and/or impactors. All the tests were performed on aerosol in twenty underground coal mines. The coefficients of mass-relative concentration were 0.067+/-0.054 (Mean+/-Standard deviation) (range: 0.006-0.172). The relationship between relative concentration and temperature was not significant statistically. Also, the relationship of relative concentration and relative humidity was not significant. Mass concentration and relative concentration were 5.31+/-5.22 mg/m3 and 162+/-163 CPM (Mean+/-Standard deviation) respectively. The range of mass concentration was 1.22-22.69 mg/m3; relative concentration 16-628 CPM. The relationship of mass concentration and relative concentration was not significant in these ranges.

This is an analysis of 174 patients classified as generalized vitiligo by Ortonnes' classification during the period from May till December in 1985. The retults are summarized as follows. There were 89 females(51.l%) and 85 males(48, 9%). 2. The mean age of onset was 24.2 years(male: 23.4, female: 24. 8). 3. The mean age at the first visit was 33 years(male: 32. 2, female: 34, 8) 4. The mean duration of t.he disease was 10. 8 years (male: 10. 3, female: 11. 3). 5. The mean interval between onset and visiting was 9 years(male: 8. 8, female: 10). 6. Mode of onset was unicentric in 90, 2% and multicentric in 9. 8% 7.The most common site of initial involvement was abdomen(15. 0%). 8. The most common precipitating factor was trauma(11%). 9.The most common previous treatment was sunlight irradiation after application of topical oxoralene(33.3%). 10. The most common degree of depigmented lesion was 5~10%.(39.7%). 1l. Family history was present in 12% and thyroid disease was associated in only one case.

BACKGROUND AND OBJECTIVES: We determined the localization of leukocyte-type 12-lipoxygenase (L-12-LO) in murine nasal mucosa and to investigate the expression of L-12-LO according to the development of murine nasal mucosa. MATERIALS AND METHOD: Immunohistochemical staining was done on the nasal mucosa of mice at gestational days 16, 17, 18, and mice at postnatal days 1, 3, 7, 14, and adult mice. Alcian blue (pH 2.5)-periodic acid Schiff staining on murine nasal mucosa was performed. RESULTS: In murine nasal respiratory mucosa, the expression of L-12-LO was noted in ciliated epithelial cells, basal cells, serous acini, and secretory ducts, but it was not found in the mucous acini and goblet cells. In olfactory mucosa, the expression of L-12-LO was noted in the olfactory receptor cells, supporting cells, and basal cells. The expression in respiratory mucosa according to the development was strongly noticed from the gestational day 16 through postnatal day 7. The expression in postnatal day 14 and adult mice was weaker than in the previous time point. The expression in olfactory mucosa showed no difference throughout the developmental stage. CONCLUSION: As a result of this study, we found the exact localization of L-12-LO in murine nasal mucosa, and we also found the different expression of L-12-LO between the respiratory and olfactory mucosa. This fact suggests the possible involvement of L-12-LO in the development of murine respiratory mucosa.

This study analyzes important factors of foodservice in school through comparison of students' satisfaction of using foodservice in Korea and US in order to meet students' expectations. The survey was composed of 4 categories including menu, service, hygiene, and facility and it was carried out in both countries to evaluate satisfaction. First, comparison of satisfaction between two countries was made using t-test. Secondly, multiple regression was performed to identify factors affecting satisfaction. As a result Korean students were more satisfied than American students in all aspects. However, regardless of nationality, the top three factors affecting the students' satisfaction were the same. The predictors were food taste (Korean 0.375 and American 0.350), menu variety (Korean 0.305 and American 0.278), and service line (Korean 0.226 and American 0.192). Despite the similarity of the predicators, it can be concluded that the difference in satisfaction level between the two nationscan be explained by the approaches to create comfortable and acceptable changes in schools' foodservice. Korea has been increasing the foodservice quality based on their objectives to provide students comfortable and positive environment when eating nutritious meals. However, US have made their main objectives on making changes to decrease youth obesity. Foodservice improvements according to continuous evaluations and surveys are necessary in order to increase students' satisfaction.

PURPOSE: The purpose of this study was to investigate the clinical manifestations and 5-year natural course of recurrent bronchiolitis or reactive airways disease (RAD) in infants. METHODS: We reviewed the medical records of infants with recurrent bronchiolitis from January 2007 to December 2007 at The Catholic University of Korea St. Mary's Hospital in Incheon, South Korea. Additionally, we telephoned their parents to confirm their present medical statuses. RESULTS: Sixty-three subjects with recurrent bronchiolitis were identified. The mean age at admission was 8.1 months and the number of males was 44 (69.8%). Of the 63 infants with recurrent bronchiolitis, inhaled corticosteroids, bronchodilators, and antibiotics were given to 62 (98.4%), 53 (84.1%), and 40 (63.5%), respectively. Among the total 63 subjects, we were able to contact the parents of 45 children by telephone. None of these children had been hospitalized during the previous one year period due to respiratory infections or for other medical reasons. Of the 45 subjects we were able to contact, 38 (84.4%) had not experienced any further respiratory difficulties at all. Five (11.1%) had been diagnosed with allergic rhinitis while two (4.4%) were being managed for asthma. CONCLUSION: Most children who presented with recurrent episodes of bronchiolitis in infancy did not show any further respiratory difficulties after five years of age.

Purchasing professionals utilize a e-commerce to sell or buy better products with good price. The marketers of agricultural products recognized that e-commerce has made significant inroads, and the Internet is fast becoming an essential tool for purchasing. The purpose of this research was to assess the realities of internet shopping malls of agricultural products including the actual condition of the sites, payment methods, order methods, membership and shipping methods. The results show that operating internet shopping mall of agricultural products are operated poorly in terms of buyer-seller relationship, payment and distribution. The results also provide some practical implication for marketers regarding the establishment of database, improvement of distribution and internet shopping mall operation, and importance of education on e-business for agricultural markets.

A total of 6043 surgical cases were performed at S.D.A. Hospital from 1973 to 1979. These were analyzed statistically according to yearly numbers and emergency states, age, sex, anesthetic methods, anesthetic technique, duration of anesthesia, anesthetic agents and mortality. These were all inpatients operated under general anesthesia, and the results are as follows. Results. 1) Yearly numbers and emergency numbers were steadily increasing. 2) Sex ratio was 65%: 35% 2887 male cases(47.7%) and 5156 female cases(52.23%). 3) More than half of the age group was adult(21 to 60 years) 4) Halothane, nitrous oxide and neuromuscular blocker were used with increasing tendency. 5) The anesthetic technique was, in more than 90% of cases, was circle absorption system. 6) General surgery cases were 40% of the total of all departments. 7) In 66.95% of anesthesias the duration was 1 to 3 hours. 8) General anesthesia group was 98.63%. 9) Deathe occurred in 6 cases our of a total of 6043 cases.
