This study was undertaken to identify factors affecting school food waste generation using a questionnaire. The subjects were 254 high school students (male; 156, female; 98) in Sacheon, Gyeongnam divided into three groups of low (${\leq}1/week$), moderate (2~3/week), and high (${\geq}4/week$) according to the frequencies of food waste. The questionnaires consisted of general characteristics, anthropometric values, dietary habits, health-related behaviors, self-perceptions of food waste, snacking patterns, and nutrition knowledge. The main reasons behind food waste were 'too much food' in the low (20.9%) and moderate (32.2%) groups, and 'no appetite' in the high group (p<0.01). The main types of food waste were rice (44.2%) > fish (18.6%) > vegetables (14.0%) in the low group, rice (54.2%) > Kimchi/vegetables (15.3%) in the moderate group, rice (56.0%) > vegetables (20.0%) > Kimchi (16.0%) in the high group (p<0.01). School food waste was significantly affected by age, gender, monthly allowance, school grade, weight, BMI, regularity of meals, time of meals, type of breakfast, starting age of smoking, and cost for snacking.

Due to the standardized urban development since the industrial era, many urban spaces have experienced non-placeness. Recently, although interest in urban landscape, history, and cultural elements has been increasing, landscape management and control measures are being implemented mainly in large cities due to the low status of rural areas in the country. From this point of view, this study tried to lay the foundation for basic research in related fields by classifying the characteristics and types of streetscapes located near large cities, and to suggest directions that should be considered when managing streetscapes in the future. As a result of the analysis of landscape adjectives, the village felt secluded due to the low density compared to the city street overall, but it did not have a unique image of the region. Three factors were derived through factor analysis, and preference was affected in the order of aesthetic, regularity, and uniqueness. In addition, the research site was classified into three types through cluster analysis, and it was confirmed that the differences by type were due to aesthetics and naturalness. On the other hand, the uniqueness is generally low in all regions, so it seems that fundamental countermeasures are needed.

This study was carried out to examine dietary habits, food frequency and dietary attitudes by gender and nutrition knowledge level in upper-grade school children. Subjects were 223 boys and 208 girls attending 13 elementary schools (5 th and 6 th graders). A self-administered questionnaire was developed to assess nutrition knowledge, dietary habits, food frequency, and dietary attitudes. Nutrition knowledge score assessed by 19 questions was significantly higher in girls than in boys. There were significant differences between boys and girls in several items in dietary habits such as enough breakfast time, dinner regularity, number of side dishes, eating speed, type of snack after dinner, and degree of saltiness of dishes. Girls consumed staple foods such as rice, noodles or bread more frequently, and consumed less frequently ramyun, fried foods, fast foods, and Chinese foods than boys. In addition, girls had more positive dietary attitudes in trying to reduce fast foods, Chinese foods, ramyun and fried foods. Also children in the high or moderate nutrition knowledge level groups had better dietary habits in frequency of meals, frequency of breakfast, enough breakfast time, dinner regularity, activity during the meal, number of side dishes, eating speed, type of snack after dinner, and better food choices by eating staple foods and vegetable side dishes, meats and beans more frequently, and fried foods, doughnuts/cakes, Chinese foods less frequently, and had better dietary attitudes in breakfast, vegetables and fruit intake than children in the low nutrition knowledge level group. Our results showed that dietary habits, food frequency and dietary attitudes were different by gender and nutrition knowledge level. These results suggest that in developing nutrition education program for elementary school children, the differences between gender and nutrition knowledge level should be considered. Nutrition education in elementary schools may change dietary habits and dietary attitudes through increasing nutrition knowledge.

The aim of this study was to determine whether Nutrition Quotient (NQ) for children, which has been developed from data on urban children, can be applied to children in rural areas. A total of 200 children (108 boys and 92 girls) in fifth and sixth grade at three elementary schools in rural areas of Gyeongbuk participated in the survey conducted during June 2012. Questionnaires consisted of items on food intake frequency and dietary behavior. Food intake data were obtained using the 24-hour recall method, and nutrient intake was calculated using the CAN-Pro 4.0 Program. Percentages of children who took less than the estimated average requirement were 76.5%, 49.5%, 45.5%, 33.5%, and 26.0% for calcium, vitamin C, iron, vitamin A, and folate, respectively. Significant associations were observed between intake frequencies of vegetables, kimchi, and fruits, and intake of vitamin C, folate, and dietary fiber. White milk and legumes showed positive correlation with intake of calcium and vitamin A. Eating breakfast, meal regularity, and diverse side dishes showed positive correlation with intake of folate and calcium. The 19 food checklist items could be categorized according to five factors. The mean NQ score of the subjects was 62.0, which was similar to that of urban children, 64.4. NQ score and factor scores for balance, regularity, and practice were significantly lower in children with lower socioeconomic level as compared to those with higher socioeconomic level. Higher NQ score showed an association with increased intake of vitamin B2, folate, vitamin C, and calcium. In conclusion, NQ offers a valuable instrument for evaluation of food habit and dietary quality of rural children as well as urban children, and children with low socioeconomic status should be monitored by testing with NQ checklist before implementation of nutrition programs.

Many cryptographic and error control coding algorithms rely on finite field GF(2m) arithmetic. Hardware implementation of these algorithms needs an efficient realization of finite field arithmetic operations. Finite field multiplication is complicated among the basic operations, and it is employed in field exponentiation and division operations. Various algorithms and architectures are proposed in the literature for hardware implementation of finite field multiplication to achieve a reduction in area and delay. In this paper, a low area and delay efficient semi-systolic multiplier over finite fields GF(2m) using the modified Montgomery modular multiplication (MMM) is presented. The least significant bit (LSB)-first multiplication and two-level parallel computing scheme are considered to improve the cell delay, latency, and area-time (AT) complexity. The proposed method has the features of regularity, modularity, and unidirectional data flow and offers a considerable improvement in AT complexity compared with related multipliers. The proposed multiplier can be used as a kernel circuit for exponentiation/division and multiplication.

This paper proposes a new fault-tolerant technique for bitonic sorting networks which can be used for designing ATM switches based on Batcher-Banyan network. The main goal in this paper is to design a cost-effective fault-tolerant bitonic sorting network. In order to recover a fault, additional comparison elements and additional links are used. A Dynamic Redundant Bitonic Sorting (DRBS) network is based on the Dynamic Redundant network and can be constructed with several different variations. The proposed fault-tolerant sorting network offers high fault-tolerance; low time delays; maintenance of cell sequence; simple routing; and regularity and modularity.

Objectives: Although breakfast is important to nutrition balance, prevention of overeating, and weight control, people in their 20s (males: 55.1%, females: 49.9%) were reported to have the highest rate of skipping breakfast in 2016 Korea Health Statistics. This study aims to examine dietary habits and nutrient intake depending on breakfast frequency among young women in Seoul. Methods: The subjects were 655 young women in Seoul from August to October 2016, and the survey was performed by using a questionnaire that included general characteristics, dietary habits, and eating behavior. Body composition was determined by bioelectric impedance analysis. Nutritional status was examined by the 24-hour recall method. Results: The participants were classified by breakfast intake frequency; '${\geq}5times/week$ (n=160)', '1-4 times/week (n=327)', and 'breakfast skipping (n=168)'. The 'breakfast skipping' group had lower frequency and regularity of meals. In addition, the 'breakfast skipping' group had a higher frequency of eating-out and late-night meals. There was no difference in total calories between the 'breakfast skipping' group and other groups, but the 'breakfast skipping' group had significantly low carbohydrate and fiber intakes. The participants showed lower intakes of calories, fiber, vitamin A, vitamin C, niacin, folic acid, calcium, potassium, and zinc in comparison with recommended intakes. Especially, the 'breakfast skipping' group had significantly lower fiber, vitamin A, vitamin C, calcium, potassium levels compared to the '${\geq}5times/week$' group. For Mean Adequacy Ratio (MAR), the 'breakfast skipping' group recorded a ratio of 0.60, which was lower than those of other groups. Index of Nutritional Quality (INQ) including fiber, vitamin C, calcium and phosphorus were significantly lower in the breakfast skipper group, compared to the breakfast eater group. Conclusions: The 'breakfast skipping' group showed low regularity of meals and a high frequency of eating-out and late-night meals. The breakfast regular eater group showed high intake of micronutrients and quality of meals was high in general. Skipping breakfast could lower nutrient intake and quality of meals, which requires attention.
