북한의 심각한 식량난 문제는 남한은 물론 국제사회의 커다란 관심사가 되어오고 있다. 식량난은 영양공급을 감소시킴으로써 노동생산성을 저하시키게 되고 결국 경제성장에도 부정적인 영향을 미치게 된다. 그러나 북한 식량난에 대한 대부분의 연구는 식량난 정도의 파악 혹은 지원이나 협력을 통한 해결방안의 모색에 머무르고 있을 뿐, 식량난의 경제적 파급효과에 대한 연구는 거의 없는 실정이다. 본 연구는 1995년 이후 북한이 겪고 있는 심각한 식량난으로 인하여 북한주민의 에너지 섭취량이 어느 정도 저하되어 있는가를 파악하고, 이러한 에너지 섭취량의 저하가 노동생산성에 어떠한 여향을 미치고 있는가를 추정하고 있다. 추정결과에 의하면, 1997년 현재 북한주민의 하루 평균 에너지 섭취량은 1,600kcal 수준으로 1994년에 비하여 약 20% 감소되었으며, 이는 노동생산성과 생산량을 약 13% 저하시킨 것으로 나타났다. 이러한 추정결과는 남한이나 중국의 경우와 비교한 결과 설득력이 있는 것으로 나타났다. 한편 이 기간중 북한 경제규모 축소의 약 30%는 에너지 섭취량의 감소에 따른 노동생산성의 저하에 기인하는 것으로 추정되었다.

센서 네트워크는 관심이 있는 현상을 관찰하기 위해서 관찰지역 내에 뿌려진 센서 노드들로 구성된다. 센서 네트워크를 구성하는 각 센서 노드들의 수명은 전체 센서 네트워크 수명에 많은 영양을 준다. 하나의 센서 노드가 수명을 다 했을 때 이는 센서 네트워크의 분할을 가져 올 수도 있다. 그러므로 모든 센서 노드들이 공평하게 다 같이 오래 사는 것이 전체 센서 네트워크의 수명을 연장하는 것이다. 이 논문에서 우리는 클러스터 기반의 에너지 효율적인 라우팅 프로토콜(Cluster-eased Power-Efficient Routing Protocol CBPER)을 제안하였다. 제안된 프로토콜은 여러 개의 유동성 싱크 노드를 가진 센서 네트워크에서 에너지 효율적인 데이터 전송을 지원하며 효율적인 라우팅을 위해서 각 센서 노드의 위치정보를 기반으로 만든 그리드 구조를 이용한다. 제안된 프로토콜의 성능을 평가하기 위해서 두 계층 데이터 전송 라우팅 (Two-Tier Data Dissemination Routing： TTDD) 프로토콜과 비교를 하였다. 실험결과는 CBPER 프로토콜이 TTDD 라우팅 프로토콜 보다 좀 더 에너지 효율적이라는 결과를 보여 준다.

대만정부는 1968년도에 오리에 대한 체계적인 연구를 수행할 수 있도록 연구소를 설립하여 오늘날 5개의 연구서에서 수많은 석박사가 육종, 질병, 영양, 관리에 이르기까지 체계적인 연구를 하고 있고 농민들은 이들의 기술적인 지원과 교육을 받아 오리알과 고기를 효율적으로 생산함은 물론 전체 생산량의 약 40% 가량을 일본에 수출하여 외화소득을 올리고 있었다. 한국처럼 단순히 종압(종자용 어미오리)을 수입하여 병아리를 부화 생산하는 단계를 넘어서 육종을 활발히 하여 건강하고 경제적인 오리를 기르고 있었다. 우리나라에서 큰 문제가 되고 있는 질병인 오리 혈증 바이러스성 간염, 바이러스성 장염은 별로 큰 문제가 되지 않고 가금콜레라(양계의 C.R.D와 유사)가 첫번째 중요질병이라고 하는 등 질병 발생양상도 크게 차이가 있었다. 바이러스 간염의 경우 대만은 백신을 접종하여 거의 100% 예방하고 있는데 우리나라는 아직 개발완료 단계인 것으로 알려지고 있다.

This study is performed to evaluate the effectiveness of a weight management program for overweight and obesity office workers; comparing their changes in the anthropometry, biochemistry, nutrient intakes, and exercise performance before and after the obesity management program. This program was performed on 39 workers, who are overweight or obese, over BMI 23 for 6 months in Jeollabuk-do public institution. As the results of this study suggests, triceps thickness (TT) of male subjects was significantly decreased (P<0.05). Waist circumference (WC), and hip circumference (HC) of the total subjects were significantly decreased after the weight management program (P<0.05). The biochemical result of the Total cholesterol (TC) (P<0.05) and LDL cholesterol (LDL-C) (P<0.01) was significantly decreased in male subjects. The results of abdominal computed tomography (CT) also showed that subcutaneous fat area (SFA) of male subjects was significantly decreased after the weight management program (P<0.01). The nutrient intake's results of female subjects, who took Fe, Vit B2, and niacin, were increased significantly after the weight management program (P<0.05). The nutrition knowledge score of male subjects was significantly increased (P<0.05), and a muscular endurance of the physical test was significantly increased after the obesity management program (P<0.01). At the work place, workers need a systemic health and obesity management program to improve their work efficiency and quality of life. After this study, the program should be developed and supported continuously to maintain positive results from this study.

BIDANI is the action-research program. BIDANI aims to be truly a people's program embodying their own activities and aspiration. BIDANI sees an integrated development approach at the community level with participatory services embodied in a Barangay Integrated Development Plan(BIDP) designed by the people themselves. Community situational analysis is conducted by the people to identify the priority problems and potential resources in the barangay. Participatory planning, using the “bottom up” apporach, is exercised to formulate a BIDP. Proper motivation and advocacy encourage barangay people's participation. Accessibility and efficiency in the use of various services and resources of government and private agencies increase. Family groups who are at high-risk to malnutrition become aware of the importance of nutrition through their participation in development program activities. Integration of political and socio-economic concerns at the lowest level is operationalized. Implementation and sustainability of the program on a wider scale from a model project to a model program is facilitated through institutionalization at the municipal/city level with the mayor as the project director. “Top to bottom” planning through a City/Municipal Integrated Development Program(C/MIDP) interacts with “bottom up” planning at the barangay level. The establishment of a local Training School for Barangay Development(TSBD) in each municipality and city for continuing education of indigenous village workers and barangay people is a vital component for success and viability. The role of non-political entities such as academic institutions and non-government organizations, as catalytic agents of development, is stressed.

The study was carried out to investigate growth of 48.6-L pot-cultivated 1-year-old 'Fuji'/M.9 apple trees depending on different levels of nitrogen concentration. While rise in tree growth was paralleled with increase of nitrogen concentration, more than 32 mM of nitrogen rather restrained tree growth. In particular, growth of 16 mM of nitrogen treated trees was satisfied with criteria for production of high-quality pot-cultivated nursery stocks. Although mineral contents of leaves were higher in 8 and 16 mM nitrogen treatments than commonly recommended mineral contents in apple orchards, such somewhat surplus minerals could be helpful for tree growth after transplanting to apple orchards. In addition, our result indicated that soils of 8 and 16 mM of nitrogen treated pots met appropriate criteria for soil chemical property of apple orchards. Thus, in the light of tree growth, mineral contents of leaves, and soil chemical property in the pots, 16 mM of nitrogen treatment is considered to be suitable for production of 1-year-old 'Fuji'/M.9 apple potted trees.

Purpose: Although, the rate of skipping breakfast among adolescents has increased in recent years, there has been an increase in the consumption of home meal replacement (HMR). This study examines the recognition and preference of rice-based Korean style HMR for breakfast among adolescents in located at Jeollabuk-do. Methods: Total of 550 middle- and high-school students of Jeollabuk-do enrolled in this study signing a consent of participation. After conducting a preliminary survey, the questionnaire employed was modified according to the purpose of this study, and the self-recording method was appliedto fill out the questionnaire. Data were analyzed using IBM SPSS Statistics 25. The 𝛘²-test was performed for categorical variables, whereas continuous variables were analyzed by the independent t-test. Results: Results of this study determined that 272 students (54.6%) belonged tobreakfasteating group and 226 (45.4%) were in the breakfast-skipping group. The reasons specified by both groups for eating HMR were 'convenient to cook', 'delicious', and 'time-saving'. The a result of analyzing perception of the importance of HMR by classifying as whether to eat or not to eat breakfast, revealed that compared to the breakfast-skipping group, the breakfast-eating group considered 'hygiene and cleanliness' as important factors (p < 0.001). Considering the gender, school, and breakfast consumption, the most preferred Korean HMR were 'triangular gimbap', 'gimbap', and 'rice balls'. Conclusion: Results of this study indicate, when considering adolescents, there is a necessary for continuous researches to develop convenient breakfast substitutes that are easily consumed. Moreover, we believe that it is essential to impart proper cooking education and recipe distribution of the menu.

This study was conducted to identify behavioral characteristics of salty food intake according to saline sensitivity of adults living in a rural area. Anthropometry and blood pressure were measured and salt intake-related dietary behavior was surveyed by questionnaires through interviews with 402 subjects aged ${\geq}$ 40 years in Chungcheongbuk-Do, Korea. The percentages of overweight and obese among the subjects were 37.8% and 3.8% respectively. Mean blood pressure of the subjects was in the normal range, but the distribution of subjects who were normotensive, high normal, and hypertensive was 48.7%, 17.7%, and 33.6% respectively. Approximately 27% of all subjects habitually consumed salty food, which was the smallest group, followed by 38.1% normal and 35.1% not-salty food. However, 34.6% of the eldest group of ${\geq}$ 65 years consumed salty food. The saline insensitive group showed a higher percentage of irregular meals, overeating, speed-eating, an unbalanced diet, a preference for fried food, and habitual intake of salty foods. These subjects recognized the risk for eating salty food, but they lacked the will to reduce their salty food intake. Compared to spouses and family members, experts such as doctors, nurses, and dieticians were the most influential for reducing the salty food intake of subjects. Saline sensitive group had relatively better control over salty food intake at every meal, eating out, and even when eating salty food that the spouse preferred. The saline sensitive group ate more frequently vegetables and fruits, whereas the saline insensitive group ate more frequently hot spicy foods. In conclusion, the results suggest that it is necessary to establish a social atmosphere toward reducing salt intake at the level of the government and food industry and to set action plans to be available for nutrition education programs to reduce salt intake nationwide.

This study examined the food group and dietary nutrient intakes by sugar-sweetened beverage(SSB) intake level in high school students aged 15~18 years(n=2,377) using the 2007~2015 Korea National Health and Nutrition Examination Survey. Subjects were classified into three groups by SSB(included carbonated drinks, sports drinks, and caffeinated drinks that contained added sugars) intake level obtained from 24-hour recall method: SSB 1(SSB intake 0 g/d), SSB 2(0 g/d < SSB intake < 50th percentile) and SSB 3(SSB intake ≥ 50th percentile). Result of daily intakes of SSB were 160.6±10.5 g/d for boys and 98.6±7.1 g/d for girls and it increased for boys(p<0.0001) and girls(p=0.0280) by year. The highest intakes were carbonated drinks followed by fruit juices for boys and girls. Intakes of carbonated drinks increased as 2.7 times for boys(p<0.0001) and 1.6 times for girls between 2007 and 2015 year. Daily intakes of vegetables were the lowest in SSB 3 of three groups for boys and girls(p<0.0001), and those of fruits were lower in SSB 2 and SSB 3 than SSB 1 for boys(p=0.0013). Daily intakes of milk & milk products decreased toward SSB 3 group for boys(p<0.0001) while those were the lowest in SSB 3 of three groups for girls. Daily intakes of dietary fiber(21.3~25.3%) and calcium(49.6~59.8%) were very low compared to the dietary reference intakes. Percentage of daily intakes compared to the dietary reference intakes increased for energy for boys and girls(p<0.0001) while decreased for vitamin C toward SSB 3 group for boys(p<0.0001) and girls(p=0.0382). Those of calcium were the lowest in SSB 3 of three groups for boys(p<0.0001) and girls(p=0.0008). Ratio of excess intakes of energy/fat increased toward SSB 3 group for boys and girls(p=0.0002). Ratio of calcium deficiency was not different among groups but that was very high(85.9~92.5%). Therefore, it should be emphasized to reduce SSB intakes in order to improve diversity in food group and dietary nutrient intakes among high school students through dietary education and government support.

Purpose: This study was conducted to identify the dietary life and nutritional status of Korean elementary school students according to breakfast frequency and to clarify the relationship between breakfast frequency of elementary school students and parental dietary and social environmental factors. Methods: This study used data from the 2013 ~ 2015 Korea National Health and Nutrition Examination Survey (KNHANES VI). The subjects were 1,325 elementary school students aged 6 to 11 years old. Subjects were categorized into two groups: a skipping breakfast group (ate breakfast 0 ~ 4 times per week), eating breakfast group (ate breakfast 5 ~ 7 times per week) by sex and grade (lower grade: 1st ~ 3rd/upper grade: 4 th ~ 6 th). Results: Among upper grade boys and girls, the skipping breakfast group had a higher rate of childhood obesity than the eating breakfast group. In lower grade boys, the mothers of the skipping breakfast group had higher rates of economic activity and eating breakfast alone without family members than the mothers of the eating breakfast group. For lower grade boys and girls and upper grade boys, the skipping breakfast group had a higher rate of parents who did not eat breakfast than the eating breakfast group. The energy intake of the breakfast consumed by all subjects was less than 25% of the Estimated Energy Requirements (EER). Moreover, for upper grade boys and girls, the skipping breakfast group had a higher rate of subjects whose daily intake was below the Estimated Average Requirement (EAR) for iron than the eating breakfast group. Conclusion: Breakfast frequency of elementary school students was related to childhood obesity. The frequency of eating breakfast among elementary school students was related to the dietary life factors of parents such as breakfast frequency and dietary condition. Intake for breakfast was less than 25% of the EER, while the skipping breakfast group had a higher rate of subjects whose daily intake was below the EAR for iron than the eating breakfast group. Therefore, it is necessary to consider diverse forms of policy support such as opening nutrition education programs for parents and practicing morning meals at school for elementary school students to provide regular and balanced breakfasts.
