The purpose of this study was to acquire the better and more correct information on the school uniforms with which middle or high school students may be satisfied. We investigated clothing interest, school uniform satisfaction, school uniform modification behavior and the relationship anions those factors. The data were collected from 472 questionnaires of middle and high school students who lived in Gyeonggi-do and analyzed statistically. We found that adolescents felt a great interest in appearance, fashion, brand orientation of clothing, and they spent most of personal expenses in buying clothes. However, the extent of adolescents' satisfaction on school uniform was low. Especially, the satisfaction on status symbolism, fashion, washing & management, body comfort and economical efficiency of school uniform was found low. Three hundred fifty three students (74.8%) agreed to modify the school uniform for personality and in chase of fashion. Two hundred eighty four students (58.1%) needed partially and variously modified school uniform, and these modifications showed a tendency of tightness to the body. We also found that the higher adolescents' clothing interests in appearance, conformity, modesty and brand orientation were. the more satisfied adolescents were with the status symbolism and the washing & management of school uniform and the more affected the school uniform modification behaviors of students were. There were. however. no significant difference between the extent of school uniform satisfaction and the school uniform modification behavior, Another research of school uniform will be necessary in order to reduce the discrepancy between clothing needs for representing the appearance, personality and fashion in the present adolescents and those for representing the worthy and modest images of a student and pursuing the economic value through school uniform in the older generation. We suggest that students should consider these results when they choose school uniform and furthermore both the person in charge of schools and school uniform makers should refer to those when they design and make school uniform.

Many trails have been built and utilized in each sub-basin of Apsan Park. This study focused on the conditions and the present flora of several overused trails within three basins called Kun-Gol, Anjiroung-Gol, and Meaja-Gol in Apsan Park. There are two purposes for this study. The first is to make a plan for restoration by classifying the type of damage to these overused trails. The second is to provide preliminary data for reestablishing a more pleasant urban nature park. As a result of the survey, the average length of these trails is 9.0km and mean width is 2.0 to 2.6m. 2,108m of the sections studied(23.4% of the total) had exposed root, 3,199m of the sections studied (35.5% of the total) had exposed rock, 3,270m of the sections studied(36.6% of the total) displayed damaged pathways, and 4,841m of the sections studied (53.8% of the total) had higher soil hardness. Eighty-three areas of deterioration were found and there has been extensive property destruction. As an indication of human disturbances, the Naturalization Index and Urbanization Index appeared as: Kun-Gol, 7.0%, 5.5%; Anjiroung-Gol, 8.3%, 4.5%; Meaja-Gol 8.6%, 6.2%; in total, 7.8%, 8.3%. As a method of checking the level and extent of the damage process, an impact rating classification was used at each point on the trails. Kun-Gol had the highest rating and Anjiroung-Gol had the lowest rating in impact rating classification. With the impact rating classification, it was found that each trail would continue to worsen, meaning that roots and rocks are more likely to be further exposed and the trail width will continue to widen through overuse. An actual plan for reparations and restoration of the trails is needed through further study.

This survey was conducted to assess the utilization of health center including health sub-center and community health post and the health service demand of residents in a urban and rural unified community. Officials in Up·Myun·Dong offices visited randomly sampled 4,027 households(4.6% of total households in unified City) which included 3,337 households in urban area(4.9% of total households) and 690 households in rural area(3.7% of total households) and interviewed with heads or housewives of the households in September, 1995. There were significant differences in health-related demographic characteristics including age-sex distribution, educational level, period of residence in the community and medical insurance status of the interviewees between urban and rural areas. Of the respondents, 64.8% in urban area and 55.6% in rural replied that they had utilized the health center in the past. The most common purpose for visiting the health center was to get vaccination in urban area and to get outpatient care in rural area. The top priority health center activity that needs to be reinforced was communicable disease control and over 90% of the respondents preferred to have mobile clinic and home health care service in were also highly demanded. Eighty-six percent of the urban respondents replied that a health sub-center must be established in urban area. In the rural area, 90.3% of the respondents replied that they wanted to maintain the health sub-center and 88.3% wanted to maintain the community health post. Along with the improvement of facilities and equipments of the health center by Rural Health Service Improvement Project, new health service programs must be developed to meet the demand of the community.

Background: Noninvasive positive pressure ventilation(NPPV) has been increasingly used over the past decade in the management of acute or chronic respiratory failure and weaning of mechanical ventilation. We performed this clinical study to evaluate the usefulness of NPPV in patients who developed acute respiratory failure or post-extubation respiratory failure. Methods: We analysed thirty four patients(sixteen males and eighteen females, mean ages 58 years) who applied NPPV(BIPAP S/T, Respironics co., USA) for respiratory failure or weaning difficulty at medical intensive care unit(MICU), emergency room and general ward of a tertiary hospital. We evaluated the underlying causes of respiratory failure, duration of treatment, the degree of adaptation, complication and predictive parameters of successful outcome. Results: The overall success rate of NPPV was seventy-one percent. The duration of NPPV applying time, baseline blood pressure, pulse rate, respiration rate, $PaO_2$, $PaCO_2$, $SaO_2$ were not different between success group and failure group. But, the baseline pH was higher in the success group. Predictors of success were higher baseline pH, patients with underlying disease of COPD, improvement of vital sign and arterial blood gas value after NPPV application. The success rate in patients with post-extubation respiratory failure was eighty percent. There were no serious complication on applying NPPV except minor complications such as facial skin erythema, abdominal distension & dry mouth. Conclusion: NPPV may be effective treatment in patients with acute respiratory failure or post-extubation respiratory failure in selected cases.

The G-banding patterns of normal and of delayed spiralized chromosomes by BUdR were investigated in three established cell lines of dwarf hamsters. The results obtained were as follows: 1. The number of G-bands appeared in Chinese hamster T-233 cell line was 65. The centromeric dark band was found in No.1 chromosome and weakly stained bands were also observed in part of the centromeric regions of Nos. 2, 3, 8 and $X_2$ chromosomes. Two homologous X chromosomes were found in different banding patterns. Terminal dark bands were shown in No. 1 chromosome. No conspicuous bands appeared in No. 10 chromosome. 2. Eighty four bands appeared in Armenian hamster Y-1249 cell line. Centromeric dark bands were observed in Nos. 5 and 10 chromosomes and moderatly stained bands were also found in near the centromeric region of the long arms of Nos. 7 and 9 chromosomes. Two isomorphic X chromosomes were also distinguished by their banding patterns. 3. In Y-1313 Armenian hamster cell line, the bands were 69. No centromeric dark bands were observed in this cell line, but moderatly stained bands appeared in the centromeric area in the long arm of No. 9 chromosome. The banding patterns of these two cell lines of Armenian hamster were quite different and readily distinguished. Only No. 8 chromosome showed similar G-banding patterns. Although Nos. 5, 7 abd 8 chromosomes revealed the same number of bands in these two cell lines, the location and staining intensity were quite different. 4. Chromosomes of Nos. 1, 2, 6, $X_1$ and $X_2$ in T-233 cell line and of 1, 4, 7, 8, 9, $X_1$ and $X_2$ in both cell lines of Armenian hamster were found to be elongated due to the inhibition of mitotic spiralization by BUdR. G-banding patterns of these chromosomes were found to be identical to those of normal chromosomes in these cell lines.

Background : Many diseases like lung cancer and tuberculosis can involve cervical lymph node. Fine needle aspiration cytology(FNAC) was known as a useful screening test for the evaluation of enlarged lymph node. But the usefulness and limitations of FNAC according to disease category or physical characteristics of lymph node were not yet fully established. Methods : Retrospective analysis of three hundred forty two adult patients who performed FNAC due to enlarged cervical lymph nodes at the Seoul Municipal Boramae Hospital during the period from January 1999 to December 2002 and final diagnosis could be made by surgical biopsy, microbiology or clinical observation. Results : Among the 342 cases, 176(51.5 %) were finally diagnosed as benign nature ncluding reactive hyperplasia, Kikuchi's disease and acute suppuration. Eighty eight(25.7 %) were diagnosed as tuberculous lymphadenitis, 66(19.3 %) as metastasis, and 12(3.5 %) as lymphoma. Tuberculosis, metastasis, and lymphoma all showed significantly larger diameter, longer duration of lymph node enlargement. There were higher frequency of supraclavicular involvement in the cases of tuberculosis and metastasis. The overall diagnostic sensitivity of FNAC was 88.0 %, and 88.6 % in benign nature lesion, 77.3 % in tuberculosis, 90.1% in metastasis and 58.3 % in lymphoma. The diagnosis of tuberculosis was made by FNAC in 68 cases (77.3 %) among 88 cases. Lung cancer(43.9 percent) was most frequent cause of cervical lymph node metastasis. Diagnostic sensitivity of FNAC was significantly lower in the supraclavicular than other cervical lymph node(80 % vs. 91.3 %) and not correlated with disease nature, node size or number. Conclusion : Though FNAC was a reliable screening test for enlarged cervical lymph node enlargement, the diagnostic sensitivity was low in the case of lymphoma or when the enlarged lymph node was located at the supraclavicular area.

Purpose: The postoperative hospital stay after gastric cancer surgery is usually 8 to 14 days. The main reason for a prolonged hospital stay may be the 3 to 4 day period of postoperative starvation. The aim of this study is to investigate the feasibility of a critical pathway for early recovery after gastric cancer surgery, and this pathway included early postoperative feeding. Materials and Methods: One hundred three consecutive patients who underwent gastric resection and reconstruction for gastric cancer from October 2007 to June 2008 at St. Mary's Hospital were prospectively enrolled in a fast-track critical pathway. The pathway included minimal preoperative procedures, optimal pain relief, proper fluid administration, early mobilization and early enteral nutrition at postoperative 1 day. The exclusion criteria were determined preoperatively, intraoperatively and postoperatively. Results: Of the 103 patients, 19 patients were excluded for preoperative (5), intraoperative (7) and postoperative (7) reasons. Eighty-four patients (81.6%) were included in the fast-track critical pathway. Sixty-eight (88.6%) of 84 patients were discharged at the planned 8 day after surgery during the initial period of the study, and the postoperative hospital stay was shortened up to 6 days during the more recent period. Postoperative complications occurred in 22 patients (26.2%), and these were gastrointestinal track-related complications in 6 cases (3 cases of ileus, 1 case of stasis and 2 cases of leakage) and infection-related complications in 8 cases. There was no statistical difference in the incidence of morbidity according to the clinic-operative features that included age, gender, stomach resection and lymphadenectomy. Conclusion: The fast-track critical pathway with using the available exclusion criteria was a valid option for patients who underwent gastric cancer surgery.

Puorpose: The purpose of this study was to evaluate the usefulness of $^{99m}Tc$ DMSA scintigraphy on the dignosis of a renal scar in children with urinary tract infections. Materials and Methods: Eighty three patients were included in this study, who were diagnosed as the urinary tract infection on the basis of symptom, urinalysis and urine culture. $^{99m}Tc$ DMSA scintigraphy and voiding cystoureterography were peformed within 7days before the treatment in all patients. We classified the scintigraphic findings as follow s : 1 ; a large hypoactive upper or lower pole. 2 ; a small hypoactive area. 3 ; single defect resulting in localized deformity of the outlines. 4 ; deformed outlines in a small or normal sized kidney. 5 ; multiple defects. 6 ; diffuse hypoactive kidney without regional impairment. Follow-up scintigraphy was done at least 6 months after the initial study. When the abnormality on the initial scintigraphy was not completely resolved on the follow-up scan, the lesion was defined as containing a scar. Results: One hundred and fifteen renal units of 166 units(69.3%) showed abnormal findings on the DMSA scintigraphy. 65 units(56.5%) was diagnosed as containing renal scars on follow-up scintigraphies. Incidences of renal scar among renal units showing pattern 3, 4 and 5 on the initial scan was 75%, 78% and 78%, respectively. Whereas many of renal units showing 1, 2 and 6 pattern were recovered(65%, 76%, 50%). Sensitivity, specificity and accuracy of pattern-based DMSA scintigraphic findings on the diagnosis of renal scar was 76.9%, 85.1% and 81.9%, respectively. VUR was significantly associated with the renal scar when the initial DMSA shows unrecoverable findings(pattern 3, 4, 5). Odds ratio of the renal scar in a kidney showing unrecoverable initial scintigraphic findings was 19.1. Odds ratio in a kidney with mild or moderate-to-severe VUR was 3.5 and 14.4 respectively. Conclusion: In the urinary tract infection, renal scar was significantly developed in a kidney showing unrecoverable findings on the initial DMSA scan and VUR on voiding cystoureterography.

The objective of this study was to investigate the effect of restricted feeding to pullet on growth and endocrine profile in layers(Isa brown). One thousand eighty brown-layer chicks were divided into three treatments; conventional feeding(ad libitum) and two restricted feedings(80% of conventional diet) for 70 weeks. One of restricted feeding started from seven to seventeen weeks of age, and the other started from twelve to seventeen weeks of age. Diets were formulated by NRC(1994) recommendation. Body weight and feed intake were measured every two weeks, and body composition and organ weight analyzed every week in rearing period and every eight weeks in laying period. Blood was collected at weighing body weight and was analyzed for the concentration of insulin-like growth factor-Ⅰand estradiol. Body weight and feed intake decreased as restriction of feeding begins comparing to ad libitum group(P<0.05), but reached to similar body weight and feed intake at 20 wk of age regardless of restriction. There were no significant differences in development of digestive tract and attached organs among the treatment groups. During rearing period, however, they were slightly higher in restricted group which was low in body weight. In terms of body composition, fat contents of restricted group were significantly lower(P<0.05) than that of ad libitum group around 1,000 grams of body weight. High concentration of IGF-Ⅰwas observed.

Purpose: This study was performed to compare total phenolic contents, in vitro antioxidant capacity, and reduction effect of Korean food groups on ex vivo DNA damage in human cells and analyze correlations between each indicator. Methods: Vegetable foods in the Korean diet based the results of the KNHANES V-2 (2011) were classified into 10 food groups: cereals, fruits, vegetables, nuts, kimchi, seaweeds, potatoes, mushrooms, legumes, and oils. Eighty-four foods constituted more than 1% of the total intake in each food group and finally designated as vegetable foods in the Korean diet. Total phenolic content of each food group was measured. Further, in vitro antioxidant capacity was measured based on DPPH radical scavenging assay, TEAC assay, and $ORAC_{ROO{\cdot}}$ assay. Ex vivo DNA damage in human lymphocytes was assessed using comet assay. Results: Total phenolic contents of food groups of the Korean diet increased in the order of mushrooms, fruits, vegetables, seaweeds, and kimchi. Meanwhile, antioxidant rankings of food groups as mean values from the three in vitro test methods increased in the order of mushrooms, seaweeds, vegetables, kimchi, and fruits. Protection against ex vivo DNA damage in human lymphocytes was highest in mushrooms, followed by vegetables, fruits, seaweeds, and kimchi. The rankings of the food groups for total phenolic content, in vitro DAC, and ex vivo DNA protection activity were similar, and correlations between each indicator were significantly high. Conclusion: Mushrooms, fruits, vegetables, and seaweeds among the tested food groups in the Korean diet showed high total phenolic contents, in vitro antioxidant capacities, and protection against DNA damage. Correlations between each indicator in terms of total phenolic content, in vitro antioxidant capacity, and ex vivo DNA protection between each food group were found to be particularly high.
