The objective of this study was to determine the perceptions and knowledge of farmers of heat stress and tick resistance in cattle. A cross-sectional survey was conducted and 110 farmers in four villages in the sour and sweet velds of the Eastern Cape Province, South Africa were interviewed. The associations among area (municipality), gender, age, level of education, employment and religion were computed using Chi-square tests. The majority of the respondents had on average 4 bulls, 4 cows, 4 heifers, 4 calves, and 4 oxen. Milk was considered as the major (28.3%) reason for keeping cattle. Most farmers owned non-descript (72.6%), and Nguni (45.3%) cattle because of their heat tolerance (54.7%), tick resistance (54.7%), and milking ability (28.2%) traits. Excessive panting (56.6%) and disease transmission (76%) were regarded as the major effects of heat stress and tick infestation in cattle, respectively. About 50% of the respondents agreed that hair length influences tick resistance and 47.17% considered coat colour when acquiring cattle. In the sampled areas, ticks were prevalent in the summer season (93%), and 77.36% of the respondents use acaricides every fortnight. Gall sickness was reported to be a major problem in the cattle herds by 36.79% of the respondents. Our results showed that farmers in the two municipalities had knowledge of cattle adaptation to heat stress and tick resistance.

This study was conducted to illustrate standard menu items available in the school foodservice industry, and to establish higher nutritional standards in this industry. We reviewed menu items from 125 middle and high schools from the Seoul area for three months. These menus were then classified into 12 representative menu items, as follows: beef seeweed soup, egg soup, sliced rice rod soup, spaghetti, sauted squid with hot sauce, fish cutlet, simmered pork-egg in soy sauce, sweet and sour meat, sauted pork, acorn starch jelly salad, cucumber salad. And standard recipes of these 12 representative menu items were established, based on a survey from 150 dietitians who completed a questionnaire of 97 questions. According to the survey results, 89% of the dietitians answered positively('yes') about the necessity of establishing standard recipes for the school foodservice industry. 69% of the dietitians were educated standard recipes for the school foodservice, 91% will use standard recipes for the school foodservice Moreover, we discovered there was a consensus on what type of menu items should be included on the menus; demographic factors only affected a small range of recommended items. In order to confirm real application of resulted standard recipe, it is required to conduct quantity food production at real foodservice and study on more suitable standard recipe.

Objective: In this paper, work time for the representative fruit crops are collected and analyzed using time-diary method, and the collected data were compared with the directly observed work time using GPS device. Background: There is no consistent conclusion which measurement method for work time is accurate. Most of the research results were collected from the environment other than rural area. Therefore, there is need to review reliability of the measurement methods for the agricultural work which are carried out for a long duration. Method: Top five crops (apple, pear, grape, sweet persimmon, and peach) were selected according to the number of farms and cultivation areas. We let fruit growers fill a work diary during one cropping period. A difference between the work-time that was recorded by the farmers and the direct observed worktime using GPS device were analyzed. Results: Average direct work time for the five fruit crops found to be 7.1% of the total work time. Conclusions and Applications: Reliability was secured by recording the daily work diary at each work stage while aware that direct observation is carried on. Data which are being collected by government institutions are obtained by the memories of the respondents. Therefore, it is needed to try the method adopted by this study in order to collect more accurate data.

In this survey, we investigated the way of thinking about meal management of housewives including the sincerity to meal preparation, the eating practices and cronic degenerative diseases related dietary behaviors, and studied the effects of above factors on the real food intakes. We also investigated the trends of health-foods and nutrient supplements usage. The results obtained from 506 housewives in Seoul were summarized as follows. Although our subjects prepared their meals habitually without special concern, they did not prefer the use of convenient foods. The food prefrence of housewivess who had more child and refered higher life status was similar with other family members. The dietary attitudes were good in large family, the higher income and the more child group. The highly educated group skipped breakfast more frequently. The mealmanagers with better education career and good living status considered for the restriction of salty foods, sweet foods, animal fats and pungent foods, and for the nutritionally balanced diet. The high income group showed great concerns about weight gain at meal times. The nutritional qualities expressed by the frequency of food group intakes were high in the better educated and living status groups, and their eating frequencies of animal protein foods and calcium sources were significantly high. Mealmanagers who had no job intaked vegetable oils through frying foods frequently. The use of health-foods and nutrient supplements was influenced by age, educational and economic level and self-estimated living status, but the trends in prevalence of both were not consistent. Health-foods were prefered by the groups of high educational career, affluent income and advanced living status, and low educational career, low income and low living status groups favored the nutrient supplements. The restrictive intake of animal fat and the use of health-food were positively correlated, which seemed that the subjects used health-foods as supplements in compensation for nutritional unbalance caused by the avoidance of animal protein foods.

This study was conducted to investigate the degree of practice of dietary behavior and dining out in accordance with intake of sodium among male and female adults aged 20 years or older residing in the Seoul Metropolitan area or Chungcheong Province. A total of 530 copies of the questionnaire were distributed from May to July, 2014. The SH group who responded that they eat a lot of sodium constituted 30.6% (158 people), followed by the SM group who responded that their sodium intake is about average at 55.7% (288 people) and the SL group who answered that they do not eat much sodium at 13.7% (71 people). Those in the SL group showed positive results for dietary behavior patterns. The SL group showed the lowest rate in terms of how often they eat harmful foods, including processed foods, sweet foods, salty foods, or food with high animal fat content such as pork belly. Positive results among the SL group were prominent in terms of avoiding over-drinking, regular exercise, and nutritional knowledge, indicating greater health management. The distribution of each group in terms of self-perceived sodium intake showed significant differences across age, gender, and household income in terms of frequency of fast food intake, regularity of meals, purchase of foods with consideration of sodium amount, frequency of missed meals, balance of food intake, and health management habits.

This study was carried out to analyze the relationship between body mass index (BMI) and general characteristics, psychological factors, eating habits, dietary behaviors, and health related quality of life using survey of 335 women aged 20 to 29 years in the Seoul and Kyungin areas. The 335 study subjects were divided into 4 groups by BMI ($kg/m^2$) levels; normal group($18.5{\leq}BMI{\leq}22.9$), overweight group($23.0{\leq}BMI{\leq}24.9$), mild obesity group($25.0{\leq}BMI{\leq}29.9$), and heavy obesity group ($BMI{\geq}30$) by Asian-Pacific obesity index criteria. The family income of the heavy obesity group was significantly (p<0.05) less than that of the normal weight group. Psychological factors, such as stress and depression of the normal weight group tended to be higher than those of overweight and obesity groups. The higher BMI level had the lower self-efficacy(p<0.05) among all subjects. As the BMI level increased, the preference for sweet, salty, and hot taste was significantly high. We found that normal weight women had healthier eating habits and dietary behaviors and a higher level of health-related quality of life than did those who were overweight, mildly obese, and heavily obese women. Overweight and mildly and heavily obese women were strongly associated with decreased physical and mental health related quality of life. Therefore, weight loss is desirable, and is likely to be beneficial for health-related quality of life in obese adult women. In conclusion, this study contains evidence to suggest that obesity management programs including different strategies according to obesity are required to determine the types of programs that are suitable for adult women, prior to their initiation of a program. The findings are helpful to inform researchers and practitioners who are seeking to implement appropriate strategies to create positive changes in the health behaviors of obese adult women.
