This study aim to demonstrate and categorize the status of level of mobile information utilization of the 2030 youth generation, and to identify factors that may affect the digital divide within the generation. For this purpose, 1779 data were analyzed using materials for the 2018 digital divide survey in Korea Ministry of Science and ICT. According to the level of information utilization, the consumers were categorized into three types : reference group (46.5%), high utilization group (27.2%), and low utilization group (26.3%). There were statistically significant differences in demographics variable, consumer capabilities, living satisfaction by type of consumer. In addition, the factors influencing the digital divide of the high utilization group and low utilization group were identified compared to the reference group. It is meaningful that this study confirmed the actual gap of information utilization and raised the possibility of the digital divide within the 2030 youth generation.

This study was attempted to evaluate and explain the correlation between stress and utilization of Dispensary, Frequency of absence, Frequency of accident as the health condition of bluecollared workers. The subjects for this study were 260 workers selected conveniently from 360 workers working at one chemical manufacturer located in Seoul. The dataas measure the Stress was collected through SRRS (The Social Readjustment Rating Scale) which is developed by Holmes ＆ Rahe (1976) from 27th July to 10th August, 1983. The data of Utilization of Dispensary and Frequency of Accident were brought out from the record of Dispensary during past 8 months. The Frequency of Abscence from January to August were collected through diligence and indolence cards of each department. All collected data were analysed based on the SPSS (Statistical Package for the Social Science) program. The results of the study are as follows: 1. The average of Utilization of Dispensary was 7.4, Frequency of abscence 14.6, frequency of Accident 0.4. 2. The average score of Stress was 134 (minimum : 0, maximum : 593, Standard deviation : 109. 3) It can be considered as a slight stressed group by the requlations of Holmes and Rahe. 3. According to the analysed results of correlation between Stress and the Utilization of Dispensary, Frequency of Absence, frequency of Accident, the Utilization of dispensary and stress were significantly related (r= .1955, p<.001), the Frequency of Absence (r=.0284, p >, 05), and the Frequency of Absence (r=.0284, p>.05), and the Frequency of Accident (r= .0831, p>.05) were not significantly related with Stress. 4. In the relation between general characters of subjects and the Utilization of Dispensary, 20 to 25 aged group, women, single, christian, lent-house dwelling, 1 to 5 years employed group used at a high ratio. 5. In the relation between general character of subjects and the Frequency of Absence, men, 51 to 55 aged group, 21 to 25 years employed group indicated high Frequency, and other char-noters were not significantly related. 6. In the relation between general characters of subjects and the Frequency of Accident, women. single, 20 to 25 aged group, catholic, lent-house dwelling, below 1 year employed group showed high frequency. 7. Stress showed a significant difference only with a religion. Catholic group represented mode-rate stressed scored 209.67, and not significantly related with other general characters.

Objectives: This study was conducted to investigate the patterns of medical utilization and factors affecting medical utilization of population living in islands of province of ChungCheongNam-Do. Methods: Demographic and socioeconomic state, medical utilization of 447 persons were surveyed from Sept. 9th to Sept. 18th, 2002. Results: In elder age group and lower educational group, the rate of medical utilization was high. As subjective health states get lower, the group used medical institution more(p<0.05). The group having more number of chronic diseases showed more medical utilization. And the group who needs 2 to 3 hours to reach to the medical institution showed high medical utilization(p<0.05). The factors having negative effect on using medical institution were economic concern and lack of proper clinic in the neighborhood. Conclusions: The lower economic level and the insufficiency of medical facilities on islands affect the utilization rate negatively. More accessible and effective medical systems for these population are expected.

The purpose of this study was to investigate the effects of calcium intake levels on magnesium utilization in young and adult rats fed various levels of calcium(50, 100 or 200% of requirement) for 3 weeks. Feed intake, body weight gain, and feed efficiency ratios of the young group were significantly higher than those of the adult group. In calcium levels of tissues, serum calcium levels in young group were higher than in the adult group and kidney calcium levels in HCa(high-calcium group) were higher than in other groups. There was no significant difference in magnesium intake among age and diet groups. However, magnesium excretions through feces and urine in the adult group were higher than in the young group. Therefore, magnesium retention in the young group was higher than in the adult group. Especially in the young group, fecal magnesium excretion was increased with increasing levels of dietary calcium. Serum magnesium levels were lowest in YHCa(young 8t high-calcium) group, and there was no significant difference in liver and kidney levels among the calcium-diet groups. These results indicate that high calcium consumption promotes of fecal magnesium excretion and decreased magnesium retention rates in growing rats. Therefore, it is suggested that mineral interactions should be considered in the supplementation of dietary calcium intake for growth. (Korean J Nutrition 31(9) 1404-1410, 1998)

This study is to find out how the 4 types of calcium salt such as calcium carbonate, calcium phosphate, calcium lactate and calcium citrate in soy protein diet, the vegetable protein source, affect the calcium utilization in the body. To do so, calcium, phosphate and creatinine concentration and ALP activity in blood as well as the content of calcium and ash, the length, weight strength, and the calcium utilization in the bone were measured. Four groups of Sprague-Dawley male rats with the weight of around 180g were fed for 3 weeks with the experimental diet. Each group was fed with the isolated soy protein containing 14% of the diet and the above mentioned 4 types of calcium salt as the calcium source. The results are as follows; 1. There were no differences of the feed intake, weight gain, and feed efficiency among groups. 2. ALP activity in blood was sinificantly high in calcium lactate group(P<0.05), but there were no differences of concentration of calcium, phosphates, and creatinine in blood among groups. 3. The weight, calcium content, calcium ratio in ash and the strength of bone were low when calcium lactate was provided(P<0.05). 4. The content of calcium in the liver was high in calcium lactate group and calcium citrate group(P<.0.05). 5. The exceretion of feces was low in calcium lactate group(P<0.05) and the excretion of urine was also relatively low. In addition, the ratio of absorption and the retention of calcium were high(P<0.05). In summary, out of four types of calcium salt such as calcium carbontate, calcium phosphate, calcium lactate and calcium citrate when calcium lactate was provided the ALP activity in blood was high and the weight, calcium content, calcium ratio in ash and the strength of bone were low. In calcium utilization, the ratio of absorption and retention of calcium were high, however it has lower effect than 3 other calcium types in improving weight, the content of calcium and the strength of bone.

This study examined the factors affecting social welfare service utilization of general group and low-income group. The following influencing variables were selected based on the model developed by Anderson and Newman(1973): predisposing factors, enabling factors, need factors. The result shows that in both group the possibility of service utilization is high in case of having a spouse, more family members, feeling one's health ill, no chronic disease. And service use level is high in case of having no spouse, lower income in general group, higher income in low-income group, more family members, feeling one's health ill, having a chronic disease. In addition, the higher service use level is associated in low-income group with men rather than women, younger age, low education, the unemployed rather than the employed, urban residents, low life satisfaction. These findings provide implications and suggestions that each income group has various characteristics and needs, so it is necessary to provide comprehensive and appropriate services through the investigation for potential service recipients' needs.

Background: Kawasaki disease (KD) is an acute febrile, systemic vasculitis as a leading cause of acquired heart disease in children. Intravenous immunoglobulin G (IVIG) and aspirin are the standard initial therapy in the treatment of acute KD. The purpose of this study was to investigate drug utilization in children with KD, and to compare "IVIG + high-dose aspirin" and "IVIG + moderate-dose aspirin" in preventing cardiac complications. Methods: We analyzed pediatric patient sample data compiled by the Health Insurance Review & Assessment Service from 2010 to 2015. We identified patients with KD using the KCD-6 code of M30.3. We excluded patients in chronic phase or ${\geq}1$0 years. We also excluded patients who were diagnosed KD in November or December. Drug utilization pattern were assessed in acute KD patients and 30-day and 60-day cardiac complications were investigated between "IVIG + high-dose aspirin" group and "IVIG + moderate-dose aspirin" group. Results: In acute phase, IVIG was administered to 95.8% patients, and 57.1% patients were prescribed moderate-dose aspirin and 25% patients were with high-dose aspirin. Steroid use was rapidly increased from 4.0% in 2010 to 11.3% in 2015. Both 30-day and 60-day cardiac complications occurred less in "IVIG + high-dose aspirin" group compared to "IVIG + moderate-dose aspirin" group, but not statistically significant (0.9% vs 1.8%, p=0.252 for 30-day complication rate; 1.5% vs 2.7%. p=0.073 for 60-day complication rate). Conclusion: We were not able to demonstrate which aspirin therapy is superior for preventing cardiac complications in acute KD patients and further research is warranted.

Brain serotonin and its utilization was investigated on stressed rats after feeding high tryptophan diet for a month. High tryptophan fed rats displayed significantly higher level of serum tryptophan, brain tryptophan, serotonin (5-hydroxytryptamine; 5-HT) and 5-hydroxyindoleacetic acid (5-HIAA) than the control diet fed rats. When rats were treated with 3 hour immobilization (IMMB) stress, serotonin turnover was slightly increased, but not statistically significant, in control diet group rats. However in high tryptophan diet rats, 3 hr IMMB stress resulted in statistically significantly (p<0.05) decreased the serum tryptophan, brain tryptophan and 5-HT level. The concentration of 5-HIAA was significantly increased indicating accelerated utilization of the brain 5-HT of the high trp. fed rat. The utilization pattern of the serotonin was found to be similar among young and adult rats. Rats on a tryptophan enriched diet displayed higher coping ability to the stress as they exhibited smaller increment of corticosterone level. A possble involvement of opioid system was suggested in serotonin utilization by measuring total $^{3}$[H]-naloxone binding in brain.

Objectives: This study investigated the utilization and satisfaction of lunchbox by considering the dietary lifestyle of the consumer, in order to refine the purchasing behavior of adults with experience in using lunchboxes, and to provide basic data for efficient menu configuration and direction towards improvement. Methods: A total of 600 adults in Seoul and Gyeonggi-do answered a self-administered questionnaire designed to investigate general characteristics, utilization, menu preference, satisfaction, prospection, and improvement of lunchbox, according to the dietary lifestyle. Results: The study subjects were classified into 5 groups: 'taste seeking group', 'safety seeking group', 'health seeking group', 'economic seeking group' and 'convenience seeking group. Considering purchase value of the lunchbox, the 'taste seeking group' had a high utilization rate (35.1%) for prices less than 4,000 won (P < 0.05). Lunchboxes were mainly purchased at the lunchbox store (43.3%) and convenience store (37.7%). The important factor that contributed to purchasing a lunchbox was taste (61.3%), which was highest in the 'taste seeking group' (P < 0.01). The 'health seeking group' showed the highest preference for the low-salt diet lunchbox menu (26.0%) (P < 0.05). The satisfaction of 'health seeking groups' was lowest when considering addition of condiments (2.34%), origin of ingredient (2.59%), and provided calorie (2.81%) (P < 0.05). The overall response indicated future use of the lunchbox (69.6%) (P < 0.01); 35.8% respondents recommended the purchase of lunchbox, where convenience of purchase was the highest factor contributing to recommendation (50.2%) (P < 0.05). Conclusions: Taken together, our results indicate that taste was emphasized in every group purchasing the lunch box. Convenience of purchase was the highest factor contributing to satisfaction, which was relatively low when considering addition of condiments, nutrition and origin of ingredients. We propose that it is necessary to improve the development of various menus for increasing satisfaction by selecting the right ingredients contributing to good health of the consumer.
