The purpose of this study is to evaluate the relationship of blood pressure with dietary habit and level of physical fitness of middle-aged male workers by age. The study subjects included 511 male employees who have worked at a company in C City, whose age was more than 40 years old. Between April 10 and May 30. 1998, all of the study subjects measured physical fitness (Balance, strength, power, agility, flexibility and endurance) and blood pressure. A questionnair was administered for dietary habit and socio-demographic characteristics. The average age (SD) of the study subjects was 46.61(3.98) years. The study subjects were classified by age into 3 groups; 40-44 aged group(34.6%), 45-49 aged group(41.3%), and 50-54 aged group (24.1%). The score of dietary habit of 40-44 aged group was $69.77{\pm}5.82$. that of 45-49 aged group was $69.77{\pm}5.83$, and that of 50-54 aged group was $71.85{\pm}6.82$(p=0.005). But age of health physical fitness tend to weaken in the age of 40-44. Systolic(p=.011) and Diastolic blood pressure (p= .011) were significantly increased with age increment. Diastolic blood pressure and dietary habit of 45-49 aged group showed the significant negative-correlation(r= .280. P<0.05). and Diastolic blood pressure and age of health physical fitness of 40-44 aged group showed the significant positive-correlation(r= .182. P<0.05). On the basis of the results of this study. I hope occupational nurses should play an active role to improve dietary habit and physical fitness for prevention of hypertension with increase of age in middle-aged male workers.

This study was conducted to investigate the dietary habits and assess the dietary intake of preschool children. Food habit, preference and nutritional supplement status were investigated using a questionnaire answered by the mothers of 453 subjects aged 3 to 6 years old. Also, a dietary intake survey using a 24-hour recall method was performed by mothers of the children. It was found that 81.2% of subjects had milk, dairy products, cookies, fruit and bread between meals once or twice per day. As well, 60.3% of subjects had an unbalanced diet and 20.7% had an overeating habit. Thus, unbalanced diet was a serious problem for many of the subjects. Due to weight controls, digestion problems and allergies, 11.7% of subjects had special dietary consideration. And 26.4% of subjects were using nutritional supplements. From the 24-recall survey, it was found that all nutrient intakes were higher than the Korean RDA except calcium and vitamin A. Nutrient intakes for protein, calcium, phosphorus and vitamin B2 were significantly different by sex, and also increased with age but not significantly. Children received 35% of daily energy, 44% of daily fat and 52% of daily calcium from snacks, so snacks clearly play an important role in dietary intake. The average number of foods consumed per day by subjects was 17.6 and that dishes was 11.0. Most children consumed 4 or 5 food groups per day. In conclusion, the dietary intake of children aged 3 to 6 were deemed adequate judging from nutrient intake and dietary diversity. More attention should be paid to the nutritional value of snacks in this age group.

전화를 거듭하고 있는 IT산업의 그 중심에서 스마트폰이 활약하고 있다. 국내 시장에서도 스마트폰은 급속하게 확산되고 있지만 현재까지도 소비자들이 왜 스마트폰을 사용하는지에 대한 실증적 분석을 통한 선행 연구는 드물다. 본 연구에서는 정보시스템의 사용자 만족과 습관이론을 바탕으로 스마트 폰 사용에 대한 원인과 결과에 관해서 실증적으로 검증하였다. 본 연구는 스마트폰 사용자 278명을 대상으로 분석하였고 인지된 유용성과 사용 용이성이 스마트폰 만족에 긍정적인 영향을 주는 것으로 나타났다. 흥미로운 발견은 사용자 만족이 스마트폰 사용 습관과 탐색적 사용에 (+)정의 영향을 주지만 충분한 활용에는 영향을 주지 않는 것으로 나타났다는 것이다. 이는 습관이라는 매개 효과가 충분한 활용에 영향을 주고 있으며 자기효능감의 통제변수가 영향을 주기 때문이라고 할 수 있다. 마지막으로 스마트폰을 사용하면 할수록 사용자는 탐색적으로 새로운 스마트폰 기능에 관심을 기울이는 것으로 조사되었다.

치열해지고 있는 커피 시장에서 고객들의 커피 구매 메커니즘을 이해하는 것은 점점 중요해지고 있다. 고객들의 커피 구매 결정이 빈번하게 발생하지만, 대부분 서비스 경영 연구들에서 서비스 습관이 중요한 역할을 함에도 불구하고 고려되고 있지 않다. 본 연구에서는 이런 한계를 극복하고자 재구매 의도와 서비스 습관을 커피 구매의 핵심 선행 요인으로 고려하였다. 그리고 고객 만족, 서비스 품질, 브랜드 인지도가 고객들의 커피 구매 행태에 미치는 영향을 살펴보았다. 제안한 연구 모형은 여대생 233명을 통해 검증하였으며, PLS를 활용하였다. 연구 분석 결과 고객들의 커피 구매는 서비스 습관만 커피 구매에 유의한 영향을 미쳤고, 재구매 의도는 유의한 영향을 미치지 못했다. 고객 만족과 브랜드 인지도는 서비스 습관 형성에 핵심적인 역할을 담당하였다. 또한 서비스 품질은 고객 만족에만 유의한 영향을 미쳤다.

This study was performed in order to investigate the difference of general environment, life style, dietary behavior and food habit between the obese children and normal children. The number of subject was 98 obese children, 347 normal children. General characteristic was not significantly different, however father's BMI of obese children was significantly (p<0.05) higher than that of normal children. There was significant difference between obese children and normal children in mother's office-closing hour (p<0.05). Normal children spent more time to play outdoor than obese children in their free time. Normal children slept over 8 hours, but obese children slept below 8 hours. Most of obese children (70.4%) ate too many times and most of obese children (72.4%) recognized their overweight. Parents of obese children considered that their children need to control their weight and correct their eating habits such as overeating. Obese children could not bear hunger and kept eating a meal until they feel full. Obese children preferred fried or broiled food. Therefore nutritional education is necessary to improve the food habits of obese children and to reduce the obesity rate of children.

Photosensitivity of silver halide emulsion depends on the properties of the microcrystals. Size, shape, grain distribution and chemical composition as well as the inner structure or the topography of the latent image specks affect on the optical properties and play an important role in the photographic process. In the present paper, a study on the sensitization of emulsion containing AgBrClI core/shell grains showed that for the given size, shape, halide content and crystal habit, under the optimal conditions the photosensitivity of the heterojunction type grains are different from that of the common regular grains. The optimal photosensitivity was obtained at the iodide content of 2.0 mo1%.

Given the rapid growth of social network services (SNS) such as Facebook and Cyworld, it is important to understand SNS users' decision-making processes such as purchasing and continuance intention. Especially, as a number of SNS providers such as Cyworld and Habbo Hotel recognize the sales of digital items as the main source of their profits, it is critical to in-depth understand SNS users' purchasing behaviors. In this regard, this study explores continued usage behaviors and purchase behaviors of digital items in an SNS environment using a longitudinal research method. This paper develops a theoretical model to deeply understand the key drivers of purchase behavior of digital items through constructs prescribed by two established research streams on information systems, namely continuance usage and habitual usage. Moreover, this study examines the effects of actual and ideal self-image congruity on SNS continuance intention and habit. The research model was tested by using survey data collected from 307 users who have experience with Cyworld. The analysis results show that SNS actual usage directly influence purchase behavior of digital items. SNS users' continuance intention and habit are key drivers to enhance the level of actual usage of the SNS. Both actual and ideal self-image congruity play a key role in enhancing continuance usage and habitual usage. The implication of research and discussions provides reference for SNS providers in marketing and IT strategy.

Health is easily overlooked because it doesn’t be changed good or bad due to sudden effort or indifference unexpectedly but kept in daily life. Especially, schoolchildren period, an important lifetime to develop both physically and mentally needs to be helpful to promote the growth of the body and keep well-balanced mind through balanced and nourishing diet. The purpose of this study was to develop nutrition education contents for discretional activities in elementary school. The present educational contents about food and nutrition was analysed in the curriculum of elementary school. The results showed the Korean language(20.8%) included an highest ratio in educational contents about food and nutrition, the next was the courses of physical education and wise life(18.1%, each). As the educational contents about food and nutrition in the textbook were dealt with food information (20.8%), Health․Disease(15.3%), and correct dietary habits by order. We could found more contents in the text for the higher classes than for the lower classes. But the most of the contents appeared lack of structure, profundity and continuity for the systematic nutrition education in its entirety. The developed nutrition education contents for discretional activities in this study consist of korean dinning cultures and foreign dinning cultures, correct dinning etiquette, how to choose healthy food, personal sanitary and health, nutrients and food tower, and problem for children’s nutrition as main subject. This six main subjects were composed of 23 subtitles. The teaching manual consisted of the educational goal, background, teaching plan and effect-evaluation plan, and the notice point for the effective lesson. The teaching plan was made for 30 hours and consisted of cooking course, singing/making lyrics, games in nutrition, debate on dietary habit, and role play etc which are oriented to practical learning. We intended to develop this program that attempts to improve in dietary habit of schoolchildren. It is because once formed an adults dietary habit is difficult to change. Schoolchildren’s period is the best adjustable stage. Therefore, nutrition education in elementary stage can change to dietary habit and build the awareness of health.
