The purpose of this study is to determine the prevalence of obesity and to examine the eating habits of elementary school students in Iksan city. The study was carried out on 292 students(male : 151, female : 141) in May of 1997. The average height and weight of the subjects were 141 cm and 37 kg in males and 142 cm and 36 kg in females, which were similar to the average of Chonbuk. A Weight/Length Index(WLI), Broca Index, Ro¨hrer Index(RI), Body Mass Index(BMI) and Waist Hip Ratio(WHR) were used as an obesity index to classify degree of obesity, WLI, Broca Index and RI were proper for judging child obesity and strict judgments were conducted in the order of RI, WLI and Broca Index. The subjects were classified as 30.8% underweight, 43.5% normal, 8.2% overweight and 17.5% obese by WLI and there were significant differences between height (p < 0.05) and weight(p < 0.01) according to obesity degree among the four groups. 50.3% of the boys and 55.3% of the girls ate regularly, and the main reason they didn't eat breakfast(78.4%) was due to lack of time. The frequency of snacks were 1-2 times a week(40.4%), fruits(40.4%) from market and supermarket(68.2%). According to the survey 84.6%, 77.4%, 78.1%, 69.9%, 59.9% and 86.6% of subjects didn't eat meat, fish, soysauce, instant food, sugar and seaweed respectively. Seaweed, meat, and soysauce showed low preferences. 69.5% and 74.7% of the subjects drink milk and ate kimchi respectively. By analyzing eating habits according to the degree of obesity, the rate of skipping breakfast(p < 0.01), and eating meat or fish(p < 0.05) were high in the overweight and obese groups of girls. In the boys case, the rate of not eating food in sugar(p < 0.05) was high in the obese group. Obese children need to correct their eating habits. This reasserts the importance of nutrition education in children through teachers, parents, and dietitions. The findings of this study may be applied to nutrition education to ensure better physical fitness for children.

Biogenic amines can be formed and degraded either as the result of endogenous amino acid decarboxylase activity in raw materials or by the growth of decarboxylase-positive microorgannisms under conditions favorable to enzyme activity. Three biogenic amines(Tryptamine, Histamine, Tyramine) were intensively investigated by the HPLC during Kimchi fermentation at 5℃. The patterns of microfloral changes in lactic acid bacterial group, Leuconostoc, Streptococcus and Lactobacillus, were similar to the typical low-temperature fermentation. The population of microbial growth were high after 10 days and gradually decreased. The levels of Tyramine were lowered(10mg/kg) during this mid-periods(8∼16 days) but very high in initial-(15mg/kg) and final-periods (30mg/kg), in which the total acidity ranged between 0.2∼0.35% and 0.4∼0.6%, while the acidity in mid-periods revealed 0.35∼0.4% beginning the initial ripening period. Leuconostoc was highly increased in number in mid-period but slightly declined as the acidity increased, whereas Streptococcus was highly distributed in initial-period and Lactobacillus in final-period. The levels of Tryptamine and Histamine were relatively low throughout the whole fermentation period, but the profile of Tryptamine level was very similar to the case of Tyramine. Histamine was maintained at a certain level after mid-period of fermentation.

Background and Objectives : Palindromic rheumatism (PR) is known to be triggered without any obviously inciting events in most patients, although, in a few cases, attacks have been noted to relate to another events such as weather change, childbirth, ingestion of certain foods, or over-exercise. The aim of this study was to characterize the triggering factors on palindromic attacks. Materials and Methods : We evaluated sixty-four patients with PR for the presence of triggering factors and the relationship between attacks and triggering factors by interview of patients. We considered that there was an probable association between episodes and PR, if episodes within 24 hours prior to PR had triggered at least 50% of all attacks and a definite association between episodes and PR, if episodes within 24 hours prior to PR had triggered 100% of all attacks. Results : In 15 patients (35.9%), there was a possible association between episodes of PR and initiating events. In 8 patients (12.5%), there was a definite association between episodes of PR and initiating events. The triggering factors were physical over-activity including exercise (19/64: 29.7%), foods, such as rawfish, crab, and chicken, including alcohol (19/96: 19.8%). However, there were no difference between the groups with and without the triggering factor in sex ratio, duration and onset of PR, the positive rate of rheumatoid factor and involved sites. Conclusion : Our observations showed that PR was triggered by physical over-activity more than in previous reports and hypersensitivity to foods was a causative factor in some patients with PR. However, patients with triggering factors had a similiar clinical profile to patients without triggering factors.

서현숙,김영주 울산대학교 2005 생활과학논문집 Vol.6 No.2

계층에 따라 다른 가정 및 유아교육적 환경 등으로 인해 저소득층 아동의 경우 현대사회를 살아가는데 필요한 정서지능이 낮을 수 있다. 본 연구는 유·초 통합 전래놀이를 통하여 다양한 정서적 경험을 하게 한 후 정서지능간의 관계를 알아봄으로써 유·초 통합 전래놀이가 유아의 정서지능의 하위요소들과 어떤 관계가 있는지 살표보았다. 이러한 연구 목적을 달성하기 위하여 울산시 동구에 위치한 H병설유치원 유아 20명과 인근에 위치한 B병설유치원 유아 20명을 대상으로 실험집단과 통제집단으로 나누어 실험 집단에는 주 2회로 12주 동안 실외 전래놀이 프로그램을 실시하였고, 평가를 위해서는 이병래(1997)의 정서지능 체크리스트를 참고로 재구성하여 유아교육 전문가 5인의 타당성을 검증한 체크리스트를 평가도구로 사용하였으며 사전-사후 검사와 집단 간 차이 검정을 위하여 대응표본 및 독립표본 t 검정을 실시하였다. 본 연구의 결과, 유·초 통합 전래놀이 활동은 저소득층 유아의 정서지능에 유의한 효과가 나타났다. 정서지능의 하위 요소 중 유아의 자기 정서인식 및 표현능력, 자기 정서 조절 능력고 자기 동기화 능력 수준, 타인정서 인식·능력 수준과 대인관계 및 사회적 기술능력에 유의한 효과가 나타났다. 이를 바탕으로 온 동네 아이의 어른들이 함께 즐기던 전래놀이를 누구나 즐길 수 있도록 우리 정서에 맞게 발전시켜야 하며, 또한 유아의 정서지능을 높일 수 있는 다양한 교육 환경과 유아들에게 적합한 프로그램 개발로 활발히 진행되어 유아교육 현장에 제공되어져야 할 것이다. It is possible that the low-income group children have low emotional intelligence because of education surroundings. Therefore, it is important that the kinder-primary intergrade traditional plays can complement the emotional experience in childhood. This study shows how the intergrade traditional plays are related with the emotional intelligence for the low income group children. At first, I had divided 40 children into Iwo groups. One is the experimental group and the other is an controlled group. 1 had programed that they enjoyed the traditional plays twice a week for 12 weeks. 1 had estimated their El on the base of a new El checklist which is based on the Lee Byong-Rae's. Following are the findings of this study :First, the low-income group children's El is lower than the controlled group' EI. The second, the intergrade traditional plays have a large effect on children's El. 1'he third, the intergrade traditional plays have a large effect on the emotional-control, the self-motivation, the ability to identify other's emotions and their interpersonal skills.

In order to improve the disadvantages of the copolymers and the terpolymers for PSA uses, quarterpolyrners were synthesized and crosslinked. Poly(butyl acrylate-co-2-ethyl hexyl acrylate-co- methyl methacrylate-co-2-hydroxy ethyl methacrylate) (BA/2-EHA/MMA/2-HEMA) and Poly(butyl acrylate-co-2-ethyl hexyl acrylate-co-methyl methacrylate-co-acrylic acid) (BA/2-EHA/MMA/AA) have superior PSA properties compared to the copolymers and the terpolymers. The best performances of BA/2-EHA/MMA/2-HEMA as a PSA were measured when benzoyl peroxide initiator was used with the reactant mixture comprised 80% of BA and 2-EHA, 15% of MMA, and 5% of 2-HEMA. The optimum reaction temperature and time were 80℃ and 8 hours, respectively. For BA/2-EHA/MMA/AA, the best performances were obtained when the polymerization was performed at the monomer composition of BA and 2-EHA, 15% of MMA, and 5% of AA. BPO was used as initiator and the optimum reaction temperature and time were identical to those of BA/2-EHA/MMA/ 2-HEMA. Isocyanate and melamine were used to crosslink BA/2-EHA/MMA/2-HEMA and BA/2-EHA/MMA/AA, respectively. No effect of type of cross-linking agent on the peel adhesion was observed with aging. The quarter-polymers crosslinked with melamine left residues on the counter surface after weathering resistance test whereas the polymers crosslinked with isocyanate did not.

In this paper, the way that input voltage and input line current as a control variable is provided as one unit is projected. Till now, have dealed with three phase balanced load. But, in that case, total power factor compensation is difficult, for to control each phase at unbalanced load. Therefore, in this paper suggest of the scheme that three phase unbalanced load is controlled by each phase and input total power factor is compensated unit input factor. Therefore, in this paper suggest that three phase unbalanced load is controlled and the method in compensation of unit input factor to be attended by unbalanced load. Besides, the object of control is calculating quantity for input voltage and input line current for the point at issues make to improve of control method at unbalanced load. As a result, control system of each phase could maintain as unit input total power factor has been state diviation error of 2% with unbalanced load.
