This research has been surveyed on street food and snack intake status of elementary school students in the Jeon Buk region and the recognition of mothers has been observed for the objective of providing base materials for appropriate eating habits and nutritional education. As for status on intake of street food, most students (97.3%) have shown to have eaten from the street vendors while mothers assume low frequency in their child's intake of street food. Favorite street food choices had an agreement between mother and student as ddukbokki and dakkochi. Students were more tolerant in sanitation and necessity of street food than the mothers. This research shows that there is a difference in the recognition of street food between the students and their mothers. There a need required for improvement in the system as to provide quality food and to prevent poor quality food being exposed to the students. Furthermore, practical and appropriate education must be conducted at home and at school for better choices of food and a better lifestyle.

Nickel sensitivity is the most common cause of allergic metal dermatitides,, particularly in women. Women are uaually sensitized. by the objects wom close to the skin ('e.g. earring, necklace fasther, watch, suspenders, brassiere clips, etc.), and men are by occupational exposures (e.g. plating or printing industries, tools, etc.). Nickel dermatitis is frequently developed on the sites where seems to have been directly contact witb nickel substance, but secondary eruptions may develop on the areas where seems to have not been directly exposed to nickel, so that nickel dermatitie is sometimea misdiagnosed as atopic dermatitis, nummular eczema, stasis dermatitis, or other dermatitides. The authora prcsent two cases of nickel dermatitis confirmed by patch test with 2. 5% nickel sulfafte; first case-a 22 years old female who has erythemat,ous maculopapular patches on her ears, around neck, left wriat, elbows, and abdomen; second case tkat was previously misdiagnosed as mummular eczema-a 18 years old female who has large oozing and crusted patches on both lateral aspects of her right thigh and back, The authors reviewed the incidence of nickel sensitivity during past years in korea and the clinical aspect of distribution of nickel dermatitis.

Relatively little is known about the neurobiology of insomnia, despite its wide prevalence and broad medical impact. Although much is still to be learned about the pathophysiology of the disorder, identification, systematic assessment, and appropriate treatment are clearly beneficial to patients. Recent research, using quantitative EEG, polysomnography (PSG), multiple sleep latency test (MSLT) and neuroimaging techniques, suggests that some broad areas can be identified as possible pathophysiological models. Sleep-wake homeostat model hypothesizes a failure in homeostatic regulation of sleep, an attenuated increase in sleep drive with time awake, and/or defective sensing of sleep need. Circadian clock model hypothesizes a dysfunctional circadian clock, resulting in changes in the timing of sleep-wake propensity that are incompatible with normal sleep. Intrinsic sleep-wake state mechanism model suggests that abnormal function of insomnia comprises the systems responsible for expression of the sleep states themselves. Extrinsic over-ride mechanism (stress-response) model suggests that insomnia reflects the consequences of overactivity of one of the systems considered "extrinsic" to normal sleep-wake control. Many current therapies for insomnia are based on these physiological models. Several attempts have been made to create a physiological model that would explain this disorder and could be used as a foundation for treatment. However, it appeared that no model can fully explain and clarify all aspects of insomnia. Future research should be necessary to expand our knowledge on the biological dimensions of insomnia.

Upper gastrointestinal (UGI) hemorrhage remains one of the more common cause of emergency hospital admissions. The majority of patients with ulcer bleeding will not have recurrent bleeding, but 25% of patients will have recurrent or continuous bleeding and require further therapy. Endoscopy is the preferred investigative procedure for UGI bleeding because of its accuracy and low complication rate. Although no study has clearly demonstrated improved mortality rates attributable specifically to the use of endoscopy, it is likely that improved therapeutic outcome lags behind diagnostic advances. All of these 4 patients died eventually due to the massive UGI bleeding in hospital and autopsy was done between September, 1997. and May, 1998. in National Institute of Scientific Investigation (NISI). Despite major advances in diagnostic and therapeutic capabilities, mortality from this often devastating condition remains unacceptably high. The optimal balance between operative and non-operative therapy has yet to be determined. So the close cooperation between internist and surgeon is required.

Idiopathic small bowel ulceration occurring beyond the duodenum is rare, and less than 5% of all the reported cases have occurred in children. In most of the cases, single ulcer of unknown cause is observed in jejunum or ileum. The diagnosis is difficult and usually made at the time of surgical exploration for the complications, such as perforation, hemorrhage or obstruction. We experienced a case of perforation of idiopathic ileal ulceration due to blunt abdominal trauma in a 11-year-old boy. The ileal segment including the lesion was resected and the pathologic findings were compatible with idiopathic small bowel ulceration. The clinical and pathological aspects are discussed, and the literatures were reviewed.

The prevalence of dermographism in 96 patients of acute or chronic urticaria was studied using dermographic tester. The results were summarized as follows : 1. The prevalence rate of dermographism in acute or chronic urticaria was 26.0% (25/96). 2. Dermographism was more common in acute or chronic urticaria than in the general population(p<0.005). 3. There was no significant difference in the prevalence rate of dermographiam between acute and chronic urticaria. 4. The prevalence rate of dermographism was not significantly correlated with the level of serum IgE.

This study was designed to investigate the major factors affecting selection of delivery facilities by pregnant women. Five hundred women hospitalized at 23 Seoul-area delivery facilities, such as university hospitals, general hospitals, hospitals, and clinics were selected and given questionnaires from April 24 to May 7, 1990. A total of 350 questionnaires were collected and analysed for the study. The results are as follows; 1. In general, variables which significantly affected the choice of delivery facilities included the age of women, their educational level, the educational level of their husbands, monthly average incomes and residential areas. 2. In analyzing the obstetrical characteristics of the women, those variables significantly affecting the choice of delivery facilities were the gestational period, the facilities for prenatal care, the frequency of prenatal care, the type of delivery, the frequency of miscarriage, previous delivery experiences and the awareness on prenatal care. 3. In comparing the motivation factors for selecting the delivery facilities, all the factors except convenience and need for hospitalization differed significantly among delivery facilities. 4. The factor analysis was assessed for twenty possible factors motivating the choice of delivery facilities. Six factors including personal service, scale of the facility, reputation, urgency, convenience, and experience were noted explaining by 57.7%. 5. In the discriminant analysis used to clarify the major factors affecting the selection of delivery facilities, the 16 significant variables were regarded as independent variables, and the type of delivery facilities was considered a dependent variable. The stepwise method was applied to the analysis. Detected discriminant variables were the facilities for prenatal care, scale factor, personal service factor, urgency factor, convenience factor, reputation factor, experience factor, gestational period, types of delivery, frequency of miscarriage, age and income. These 12 discriminant variables were tested, with reference to discriminant prediction, on their importance in the choice of the delivery facility, by the discriminant functional formula. The test showed a hit-rate of 67.7%. The results suggest that general characteristics, obstetrical characteristics, and motivations for selecting the delivery facilities differ significantly according to the types of the delivery facilities. This study implies that all types of delivery facilities should attempt to acommodate characteristics and motivations of pregnant women. The facilities should be prepared to increase their patients satisfaction with required medical conditions by improving service and responding to the pregnant women's preferences.
