The purpose of this study was to investigate the relation between bone mineral density and nutrient intake among normal and obese elementary students. Each subject was assigned to one of such as normal (n = 69) and obese groups (n = 94) according to their obesity indices. And they were asked for general characteristics, dietary habits and nutrient intakes using questionnaires and 24-hr recall method. They measured the sound of speed (SOS) of calcaneus using quantitative ultrasound. The averages age of the subjects were 10.6 years in normal and 10.7 years in obese group. The averages weight (p < 0.001) and obesity index (p < 0.001) of the normal group were significantly lower than those of the obese group. In dietary habits, the obese group in boys was the higher skipped breakfast than normal group (p < 0.01). The plant calcium intake of obesity in girls was lower than those of normal group (p < 0.05). The SOS in the calcaneus was 1697.6 m/s in the obese group and 1763.7 m/s in the normal group (p < 0.01). The SOS in the calcaneus was negatively correlated to weight (p < 0.01), obesity index (p < 0.001) and percent of body fat (p < 0.01). Also the SOS in the calcaneus was positively correlated plant calcium intake (p < 0.05). In conclusion, the excessive increase of weight and percent of body fat in elementary students appeared to have negative impact to bone health. And based on these results, further studies on the effects on bone mineral density of obese and nutrient intakes in needed for proper bone health.

동시 스위칭 환경에서 V\ulcorner/V\ulcorner Pin 수의 최소화를 위한 연구

배윤정,이윤옥,김재하,김병기,Bae, Yun-Jeong,Lee, Yun-Ok,Kim, Jae-Ha,Kim, Byeong-Gi 한국정보처리학회 2000 정보처리논문지 Vol.7 No.7

This paper provides a heuristic analysis technique which determines an optimal number of V\ulcorner/V\ulcorner pads meeting allowable Simultaneous Switching Noise(SN) budget, early in the design phase. Until now, in determining the number of V\ulcorner/V\ulcorner pads, designers had to simulate packaging models case by case in the design phase or roughly allocate the power/ground pins in an inaccurate way according to typical design rules. However, due to the high density and frequency trends of IC technologies, the V\ulcorner/V\ulcorner pads allocation method can affect an adverse effect on IC operations, which requires more accurate and efficient methods be devised. Thus, this paper proposes an analytic V\ulcorner/V\ulcorner pads calculation method that gives a practical help for packaging designs early in the design phase. The proposed method is applied to a design example of a 1/8x208 pin plastic quad flat package (PQFP) and the results are verified through simulation using HSPICE.

In this study, a survey was conducted among university students (119 men and 134 women) in Chungbuk province using questionnaires to investigate the variables and eating patterns related to the use of food delivery apps. A survey was conducted from March 22, 2019 to April 3, 2019. Of the total respondents, 77.2% reported that they had ordered food at least once using food delivery apps on smartphones. Further, 63.3% of the total subjects had ordered food delivery through smartphone apps once or twice a month, and the most preferred cuisine for food delivery was fast food, followed by Bunsik (Korean street food/snack), western food, and Chinese food. The average satisfaction scorefor food delivery apps was 3.8 points, and the satisfaction score was the highest with the convenient ordering process (4.0), followed by good taste (3.9) and good portion (3.8). The subjects who used smartphone food delivery apps three times or more a month showed a significantly higher frequency of instant food intake (p=0.0132), dining out (p=0.0282), and late-night eating (p=0.0047) than the subjects who ordered food using delivery apps less than three times a month. In conclusion, these study results may be applied as baseline data for dietary education among university students.

The purpose of this study was to investigate the relationship between frequency of coffee consumption, metabolic biomarkers, and nutrition intake in adult participants in the combined 2007~2009 Korean National Health and Nutrition Examination Survey (KNHANES). Subjects (2,095 males and 3,297 females) were classified according to sex and frequency of coffee consumption (${\leq}1$ time/month, ${\geq}2$ times/month and ${\leq}6$ times/week, 1 time/day, 2 times/day, 3 times/day) using food frequency questionnaires. Nutrition intake was analyzed using 24 h recall data. The 3 times/day coffee consumption group had a significantly higher age, and frequency of smokers and drinkers compared to the ${\leq}1$ time/month coffee consumption group in both male and female participants. Males in the 3 times/day coffee consumption group had a significantly lower HDL-cholesterol level, but females had a higher waist circumference compared with the ${\leq}1$ time/month coffee consumption group. Males in the 3 times/day coffee consumption group had a significantly lower nutrient density of fiber, vitamin B2, vitamin C, calcium and phosphorus compared with the ${\leq}1$ time/month coffee intake group. Females in the 3 times/day coffee consumption group had a significantly higher nutrient density of fat and niacin, but lower nutrient density of carbohydrate, calcium, phosphorus, and iron compared with the ${\leq}1$ time/month coffee intake group. In males, the frequency of coffee consumption was not associated with the levels of metabolic biomarkers. In females, the frequency of coffee consumption was positively associated with diastolic blood pressure after adjustments for multiple confounding factors, including age, BMI, smoking status, alcohol consumption, physical activity and energy intake. Coffee consumption was associated with decreased diastolic blood pressure in females. These findings suggest the importance of an awareness of the association between coffee consumption and metabolic risk.

The purpose of this study was to evaluate the sodium-related dietary attitudes, behaviors, and nutritional knowledge in university students according to the practice of dietary guidelines for Koreans established by the Ministry of Health and Welfare, Republic of Korea. Based on the total practice score related to the dietary guidelines (PDG), we classified subjects into a "low practice of the dietary guidelines (LPDG)" group (n=94, male=43, female=51) (total score of PDG ${\leq}13$) and a "high practice of the dietary guidelines (HPDG)" group (n=56, male=32, female=24) (total score of PDG >13). Subjects were asked about general characteristics, lifestyle, salt-related dietary attitudes, behaviors, and nutritional knowledge using a questionnaire. The LPDG group had more subjects who were breakfast skippers (p<0.001) compared to the HPDG group. The LPDG group (31.26) had a significantly lower score in terms of salt-related dietary attitudes compared to the HPDG group (33.77) (p=0.0042). The score for salt-related dietary attitudes was significantly higher in the HPDG (32.52) group than in the LPDG (29.91) group (p=0.0041). There was no significant difference in the total score for salt-related nutrition knowledge between the groups. The correlation analysis indicated that the dietary guidelines practice score had a positive correlation with the salt-related dietary attitude score (r=0.3593, p<0.0001) and the dietary attitude score (r=0.3443, p<0.0001) after adjustments for sex. These results show that the degree of adherence to the dietary guidelines for adults may be related to sodium-related dietary attitudes, behaviors, and nutrition knowledge.

배윤정(Bae, Yun-Jung) 한국영양학회 2016 Journal of Nutrition and Health Vol.49 No.6

본 연구에서는 국가 단위 대규모의 데이터 (2013~2014년 국민건강영양조사 자료)를 활용하여 성인 남녀별 외식으로부터 섭취하는 열량의 사분위에 따른 군간 일반사항, 영양소 및 식품군별 섭취 상태를 분석하고, 영양소별 섭취밀도 및 영양의 질적 지수를 평가하였으며, 그 결과는 다음과 같다. 남녀 모두에서 외식을 통한 열량의 섭취 정도가 높은 성인일수록 연령이 유의적으로 낮았고, 음주 빈도, 가구소득 및 교육수준이 유의적으로 높은 결과를 보였다. 또한 외식을 통한 열량 섭취가 높은 남녀 성인에서 전체 열량섭취량 및 지방의 섭취 밀도는 높게 나타난 반면, 식이섬유소, 비타민 B1, 칼슘, 인, 칼륨 및 철과 같은 미량 영양소의 섭취 밀도는 유의적으로 낮은 결과를 보였으며, 비타민 B1, 칼슘, 인 및 철의 INQ와 같은 식사의 질 지수 역시 유의적으로 낮게 나타났다. 식품군별 섭취 비율을 분석시 남녀모두에서 외식을 통한 열량 섭취가 높은 군에서 육류, 음료 및 주류의 섭취 비율이 유의적으로 높았던 반면, 곡류, 채소류, 어패류 및 해조류의 섭취 비율은 유의적으로 낮게 나타났다. 이와 같은 결과는 식생활에서 외식이 차지하는 비율이 계속적으로 증가하고 있는 현 시점에서, 외식을 많이 하는 대상자와 관련된 전반적인 영양소 및 식품군별 섭취상태를 파악할 수 있는 기초자료로써 활용될 것으로 예상된다. Purpose: The objective of the present study was to evaluate nutrient and food group intakes in Korean adults according to energy intake from eating-out. Methods: This study was a cross-sectional study based on the 2013~2014 Korea National Health and Nutritional Examination Survey, and study subjects were 5,186 males (2,151) and females (3,035) aged 19~64 years. Energy intake from eating-out was analyzed using the 24-hour dietary recall method, and groups were classified by quartile according to energy intake from eating-out. Results: Subjects who had more energy intake from eating-out tended to be younger, highly educated, have a higher income, and have higher alcohol consumption. Total energy intake and fat intake density of the highest quartile group of energy intake from eating-out were higher than those of the other groups. However, fiber, vitamin B1, calcium, phosphorus, potassium, and iron intake density levels were significantly lower in the highest quartile group of energy intake from eating-out. The highest quartile group of energy intake from eating-out consumed significantly more meat and beverages compared to the other groups. In addition, regarding diet quality (Index of nutritional quality), significantly lower vitamin B1, calcium, phosphorus, and iron levels were observed in the highest quartile group of energy intake from eating-out compared to those in the other groups. Conclusion: In conclusion, in Korean adults, consumption of eating-out decreased dietary quality, including vitamin B1, calcium, phosphorus, and iron levels. Further studies are needed to confirm these findings.

본 사례 연구는 K구 주민을 대상으로 걷기동아리 결성과 활성화가 이들의 운동 실천율과 신체적 변화에 어떠한 효과를 가져오는가를 살펴보는데 그 목적이 있다. 이들의 걷기동아리 구성은 설문지로 수집된 생활체육 참여실태조사 결과(이운용 등, 2003)를 근거로 이루어졌다. 이 설문조사에 따르면, 설문 응답자 중 42%가 운동을 시작하고 싶은 장소를 ``집주변``이라고 대답하였으며, 할애 가능한 시간은 전체 55.9%가 30-60분이 가장 편안한 것으로 대답하였다. 또한, 주변에 보완되어야 할 운동시설은 29.5%가 걷기나 조깅을 실시할 수 있는 장소를 원하였으며, 걷기에 대한 교육은 전체 62.6%가 필요하다고 대답하였다. 따라서 K구 지역보건소에서는 지역사회의 주 거주형태가 아파트임을 감안하고, 아파트 단지 내의 공간을 활용하며, 적은 운동전문 인력을 활용하여 추진할 수 있는 ``걷기동아리``를 결성하는 방안을 마련하게 되었다. 이로써 지역주민의 규칙적인 걷기 운동 참여를 유도하였으며, 참여자들로 하여금 걷기 기록지를 작성하도록 하였다. 걷기 동아리는 매일 진행되었으며, 이 프로그램은 8주간 계속되었다. 걷기 기록지의 분석 결과, 주당 운동빈도는 평균 5회로 나타났으며, 1일 운동량은 약 50분가량의 걷기를 실시하였다. 운동부하 검사에 적극적으로 참여한 남성(n=6)의 경우에는 최대산소섭취량이 29.9% 유의하게 증가하였으며(p<.05), 안정시 평균혈압 역시 24.6% 유의하게 감소하였다(p<.001). 여성(n=17)의 경우에는 안정시 심박수가 평균 4.6회/분 유의하게 감소하였다(p<.05). 걷기에 대한 실천율은 전체 4.5%가 증가하였다. 걷기동아리 활동은 프로그램 종료 후까지도 활발하게 진행되고 있었으며, 걷기동아리 리더를 선정하여 자체적으로 걷기 운동을 실천하고 있었다. 통제되지 않은 현장에서의 걷기동아리 결성과 운동이 이들의 걷기 실천율을 증가시켰으며, 심폐지구력을 향상시켰다는 것은 의미가 있을 것이다. The present case study was aimed for evaluating the influence of an establishing and operating ``Walking Exercise Group (WG)`` in the community of K province to exercise participation and physical changes for the participants. The forming of WG was rationalized based on the Physical Activity Participation Survey for Community Resident (Lee et al., 2003). Based on the survey, approximately 42% of the K province residents preferred ``around houses`` for the place of exercise. 56% of the residents responded to 30-60 min for their possible exercise session. About 30% of the residents expressed that the walking and/or jogging tracks had to be established near their communities, and 62.6% of the respondent felt a necessity of an education programs for informing walking exercises. Since the major residental housing in the K province is the apartment, utilization of spaces in the complex was highly probable, and a minimum number of exercise professional could be used, a program of forming WG was highly considered. Thus, this program was expected to lead participation of the community resident to a regular exercise program, and the participants was asked to fill out an exercise record. The walking exercise was executed every day for eight weeks. Based on the exercise records, the participants walked 5 times/wk, 50 min/session. According to the exercise stress test, male participants showed elevated maximal oxygen uptake (p <.05) and reduced mean resting arterial pressure (p<.001). For the female participants, the resting heart rate was reduced (p<.05). The participation rate for walking in a daily life increased by 4.5%. The walking exercise of the residents was actively continued after the cessation of the program, and they elected a leader to keep the program going. This case report provided information that a field application of probable programs based on the needs of target population may lead an elevated exercise participation of a community residents.

The purpose of this study was to evaluate nutrient intake and meal variety with breakfast eating in Korean adolescents using data from the 2008-2009 National Health and Nutrition Examination Survey. The analysis included 1245 adolescents aged 12 to 18 years. The subjects were divided into two groups according to breakfast skipping (BS: breakfast skipping, n = 235, BE: breakfast eating, n = 1110). The BS group was significantly higher in its frequency of eating soda drinks, instant noodle, and ice cream than the BE group. The BS group consumed significantly lower quantities of plant calcium and plant protein per 1,000 kcal compared to the BE group. Also the intake of cereal and vegetables in the BS group was significantly lower than those in the BE group, however, the intake of beverage in the BS group was significantly higher than that in the BE group. The average number of foods of the BE and BS groups were 29.50 and 25.85, respectively and revealed a statistical significance (p < 0.0001). The snack intake and % energy from snack intake of the BS group were significantly higher than those of the BE group. Also, the fasting blood glucose concentrations were significantly higher in the BS group compared to the BE group. In conclusion, adolescents who skip breakfast may have lower meal variety and higher blood glucose concentrations. Therefore, in support of proper dietary management, it is necessary to promote and encourage breakfast eating. (Korean J Community Nutr 18(3) : 257~268, 2013)
