The purpose of this study was to provide basic data for nutritional education for juveniles` desirable vegetable intake by analyzing their vegetable intake, dietary habit and nutrient intakes according to gender of middle school students in Chungnam. The average age of the subjects was 15.0, height was 162.5 cm, weight was 53.5 kg and their average BMI was 20.1kg/m2. The frequency of eating supper in girls was lower than that in boys. Many respondents answered that a meal-time was 10~20 minutes. Without gender difference, more than 90% respondents thought that vegetables were good for health. As for the preference of vegetable, subjects responded, “I am in the middle”, “I like them”, “I dislike them”, “I like them very much”, and “I dislike them very much” in order, without gender difference. The frequent eaten leaf vegetable was Chinese cabbage, the frequent eaten fruit vegetable was cucumber, and the frequent eaten root vegetable was radish. The favorite leaf vegetable was lettuce, the favorite fruit vegetable was corn, and the favorite root vegetable was sweet potato. The preference degrees of taro and ginger were very low. The reasons why they liked a vegetable were that it was delicious and they ate it at home often. In addition, the reason why they disliked vegetables was that they are untasty in flavor or texture and it showed that many students had a prejudice that vegetables were untasty. The intakes of plant protein, dietary fiber, ash and INQs of dietary fiber, calcium, vitamin C, folate, vitamin E in the group with high preference of vegetables were significantly higher than those of low preference group. The study results indicate that intake frequency and preference of root vegetables in juveniles are low and the major reasons of these results are taste and eating experience of vegetables. In addition, the intake amounts of dietary fiber and folate are poor in the subjects with low preference of vegetables. Therefore, families and schools should make efforts that juveniles can recognize the importance of vegetable intake and select various vegetables properly through the development of cooking methods and systematic nutrition education.

The purpose of this study was to provide basic informations for educating juveniles on desirable body image recognition by examining their body image recognition and comparing and finding problems according togender and body mass index (BMI) in middle school students. The average age of the subjects was 15, their average height was 162.5㎝, their average weight was 53.5㎏, and their average BMI was 20.1㎏/㎡. Male students wanted togain weight and female students wanted to lose weight. As for body shape, female students thought that they were fat more often than male students. Also the more overweight the students were, the higher their concerns and experiences toward weight control. Among weight control methods, exercise scored highest in all BMI groups. Over 80% of the respondents answered that their weight control effort were not systematic such as via professional counseling. As for the frequency of eating breakfast and dinner in female students, the more a student was overweight, the lower their frequency of eating breakfast and dinner. Many respondents answered that a typical meal time was ``10∼20 minutes``. The average eating habit score for all subjects was 38.0. The eating habit scores of male students were significantly higher than those of female students, and there were no significant differences among BMI groups. Eating habit score of ``I have more than two meals with rice everyday`` in female overweight group was significantly higher than those of other two groups. These results indicate that the female students` degree of preference for a slim body shape were higher than those of male students. In addition, weight control by students is not systematic through professional counseling; instead they attempt to control their weight by themselves such as a meal skip, which lead to potential danger that they may lose weight carelessly. Therefore, correct body image recognition is greatly needed, and families and schools should make ceaseless efforts to help students properly control their weight and have correct eating attitudes.

목적: 최근 수년간의 임상 경험과 최근 발표들은 Clostridium difficile 대장염(CDC)이 더욱 흔해지고 병인성이 강해짐을 시사한다. 이 연구의 목적은 한국에서 입원 환자의 CDC의 역학적인 특징 변화를 조사하는 것이다. 대상 및 방법: 1998년 1월부터 2007년 12월까지 강남성모병원에서 CDC로 진단받은 환자를 전향 조사했다. Clostridium difficile 세포독성검사에서 양성이거나 내시경 또는 병리 증거가 존재할 경우 CDC로 정의했다. 결과: 연구 기간 동안 총 189명(남자 73명, 여자 116명)이 CDC로 진단되었다. 평균 연령은 63.3세였다. 65세 초과 환자는 103명(54.4%)이었다. 1998년부터 2007년까지 CDC의 유병률은 유의하게 증가했다. CDC의 유병률은 1997-1998년 입원환자 10,000명당 1.9명에서 2006-2007년 입원환자 10,000명당 8.82명으로 증가했다. 163건(86.2%)에서 진단 2개월 이내에 항생제 사용을 확인했다. 사용한 항생제는 평균 2.1종류였고 항생제 사용 기간은 평균 18.8일(1-240일)이었다. Cephalosporin이 가장 많은 131명(80.4%)에서 투여되었고, 다음으로 aminoglycoside는 85명(52.1%), fluoroquinolone은 24명(14.7%), macrolide는 20명(12.3%) 순으로 사용되었다. 가장 많은 항생제 사용 원인으로 수술 전후 예방적 투여(33.3%)와 폐렴(23.3%)이었다. CDC에 대한 초기 항생제 치료 반응률은 82.7% (153/184)였다. Metronidazole에 대한 반응률은 84.3%(145/172)였다. Metronidazole 초치료에 실패한 모든 환자는 vancomycin으로 성공적으로 치료되었다. Vancomycin으로 1차 치료 시 반응률은 80%(4/5)였다. 3명의 환자가 metronidazole과 vancomycin복합 치료에도 불구하고 CDC와 관련하여 사망했다. 결론: 1998년부터 2007년까지 한국에서 입원 환자의 CDC 유병률이 유의하게 증가했다. Background/Aims: Our clinical experience and recent published literatures suggest that Clostridium difficile colitis (CDC) has become more common and potentially more pathogenic in recent years. The aim of study was to evaluate changes in the epidemiological features of CDC in hospitalized patients in Korea. Methods: We retrospectively reviewed all patients of CDC diagnosed at Kangnam St. Mary Hospital from 1998 to 2007. CDC was defined as having a positive C. difficile cytotoxicity assay, or endoscopic or pathologic evidence of CDC. Results: A total of 189 cases (male 73, female 116, mean age 63.3 years) of CDC were diagnosed during the study period. The prevalence of CDC increased from 1.9/10,000 patient admissions in 1998-1999 to 8.82/10,000 patient admissions in 2006-2007. One hundred sixty three indication for cases (86.2%) of patients identified a prior use of antibiotics in the 2 months preceding diagnosis. The most common antibiotic use was prophylactic use during perioperational period (33.3%) followed by pneumonia (23.3%). The overall response rate to initial antibiotics was 82.7%. One hundred seventy two (91%) patients were initially treated with metronidazole. The response rate was 84.3%. All patients with initial failure to metronidazole were successfully treated by vancomycin. The response rate of vancomycin as first treatment was 80%. Three deaths were associated with CDC despite the use of combination of metronidazole and vancomycin. Conclusions: The prevalence of CDC in hospitalized patients in Korea significantly increased from 1998 to 2007. (Korean J Gastroenterol 2010;55:169-174)
