Children's food behaviors have been expressed in a various ways because of recent changes in their family environment. Thus, this study was performed to investigate in-depth qualitative research on the mother's perception on children's food behaviors by focused group interview. This study was designed in four steps of planning, collection of participants, process, and analysis. Participants for the focus group interview were recruited and sampled from households with elementary school students in the Seoul and Gyeonggido areas. Groups were divided by total income and education expense levels. 1) High income household: It is better to improve currently existing web sites for nutrition education. 2) Mid income household: Easy, practical, and inexpensive off-line cooking class/nutrition education classes for mothers are needed. Nutrition programs for children should be developed through mass media and be promoted in the broadcasting circle. 3) Low income household: Motivation is required for mothers' educatior and the serious nutritional problems of children should be informed through mass media and home correspondence from school. And interesting educational materials should be developed for children to read whenever they want.

The number of vegans has increased rapidly due to religious and ethical beliefs, environmental concerns, health, etc. Also, as interest in healthy and safe food increases, the demand for organic products or nutrition-enhanced products is increasing. Therefore, this study aimed to investigate the selection attributes and purchasing behavior for protein-fortified and vegan snacks. It is anticipated that the results would find use as basic data for developing protein-fortified snacks for vegans that can meet consumer needs and derive marketing strategies. A survey was conducted on 140 consumers. According to the analysis of their purchase behavior, the number of people who had purchased high-protein snacks and vegan snacks was higher than those who did not have prior experience. The reasons for the purchase of protein fortified snacks included 'meal replacement' at 'offline-convenient store/supermarket'. Vegan snacks were purchased for 'ethical beliefs, health, environment' at 'offline-vegan restaurant, bakery'. Both snacks showed above-normal preferences. However, it is necessary to improve taste and flavor when developing these products as these were the factors that negatively impacted the preferences. The attributes were factorized into the 'showing off factor', 'sensory factor', 'credence factor', and 'functional factor' and the 'sensory factor' was considered the most important.

Institutional foodservice is a type of meal provided to workers in industry and affects the health and psychological wellbeing of workers and productivity. Thus, research on customer satisfaction with institutional foodservice is important. In addition to food industry and food culture developments, the requirements of institutional foodservice customers are diversifying due to COVID-19. Therefore, the purpose of this study was to identify factors that affect customer satisfaction with institutional foodservice using a user-based approach. In this study, the quality of institutional foodservice was defined using customer satisfaction or dissatisfaction, and by using in-depth interview and open coding (a qualitative research method), we derived qualities of institutional foodservice from the user's perspective and compared these with those of previous studies. This study is meaningful as the quality of institutional foodservice was analyzed using a user-based approach, in-depth interview, and open coding and compares results with those of previous studies.

This study identifies the perceptions and choice attributes toward plant-based foods and identifies the differences between vegetarians and omnivores. We conducted an online survey of 245 vegetarians and 246 omnivores. The results reveal a significant difference between vegetarians and omnivores. Compared to omnivores, vegetarians perceived that plant-based food products would be 'good taste', 'animal-friendly', and 'consistent with their personal value'. Omnivore scores were higher in the perception that it would be 'good for health' and 'environment-friendly'. No statistically significant difference was obtained between both diet groups when considering the factor of nutrition. When considering choice as an attribute for plant-based food products, vegetarians responded that 'ingredients' were the most important, while omnivores responded that 'taste' was the most important. These results can be used as basic data for developing and promoting plant-based food products in South Korea.

The purpose of this research is to develop the management strategy for a take-out specialty sore on the basis of SWOT analysis which requires analysis of internal and external environmental informations. The survey was performed in order to gather the internal and external customer informations for a take-out specialty store. The questionnaires developed were distributed to customers (N=188) and employees (N=23) at 5 take-out specialty store branches from April 25, 2002 to April 29, 2002. The statistical data analysis was completed by SPSS WIN 10.0 for descriptive analysis, factor nalaysis, and Pearson's correlation. IPA(Importance-Performance Analysis) was applied in order to identify the critical management issues which would be explained with the organization's weakness or strength. SWOT analysis was performed through identifying the organizational strength and weakness as internal environment factors and external environmental opportunity and threat as uncontrollable external factors.

This study was to suggest the roles of social enterprises in maintaining healthy life of the socially vulnerable by creating a customized care environment through chronic disease diet management targeting the elderly at home in need of care in the community. As for the subjects of this study, 102 in-home elderly people aged 65 or older (14 males & 88 females) who needed care in the community were provided with a diet management lunch box delivery service customized for chronic diseases. Theoretical education and cooking class on chronic diseases were provided to 15 volunteers with 10 sessions, and customized lunch boxes were provided to the elderly with chronic diseases at home on that day. In conclusion, it is believed that only by increasing the level of knowledge about chronic diseases and nutritional knowledge of the elderly will it be possible to establish a proper meal plan. Since the role of volunteers is important, it is necessary to systematically seek nutritional education methods for volunteers.

In this manuscript, several effective feeding and management systems to reduce environmental pollution in swine production have been briefly introduced. It is logical that reducing the excretion of nutrients in manure should be the first step to reduce the environmental impact of pig production. it is evident that the excretion of nitrogen and phosphorus can be reduced when more digestible or available feedstuffs are used. Also, it is well known that proper feed processing can reduce anti nutritional factors (ANF) and improve nutrient digestibilities. Supplementation of effective feed additives can reduce excretion of nitrogen and phosphorus due to efficient feed utilization. These include enzymes (e.g., phytase), antibiotics, probiotics, organic acids and growth hormones ($\beta$-agonists and porcine somatotropin). One of the most effective ways to reduce pollutants from swine manure is to use synthetic amino acids in feed manufacturing. Many studies showed that reduction of 2 to 4% unit (U) of dietary protein with supplemental amino acid (AA) could dramatically reduce (15 to 20%) nitrogen excretion. Regarding feeding strategies, it has been recognized that phase feeding regimen could be used to reduce nitrogen and phosphorous excretion by feeding pigs in better agreement with age and physiological state. Feeding barrows and gilts separately, known as split sex feeding, can also decrease excretion of nitrogen and phosphorus. With the increasing concerns on the negative impact of animal production systems on the environment, animal nutritionists and producers should be aware that sustainability of animal agriculture is as important as high production performance. Therefore, some feeding and management strategies described in this manuscript will help to reduce environmental pollution in swine production. Proper combination of feeding regimen and environment-friendly diet formulation through nutritional approach will be more effective to reduce nutrient excretion in swine production system compared to single approach to do so.

The nutritional status of sulfur in rice plants grown on various field conditions different in soil fertility, fertilizers used and weather was investigated as follows. 1. The critical percentage of sulfur in rice shoot grown in a sulfur deficient field appears to be over 0.2 around 30 days after transplanting. 2. The mean sulfur contents at harvesting stage were 0.22% and 0.43% in the ear and straw, respectively and increased more in the straw by the application of ammonium sulfate. 3. The ratio of sulfur contents in the straw and ear (straw/ear) showed the increasing tendency from north to south only in the fertilized fields. But it was not as such in the percent translocation, the mean values of which were 26% and 29% in the fertilized and non-fertilized, respectively. 4. The sulfur uptake amounted to 6kg and 10kg per acre in the non-fertilized and fertilized, respectively. 5. The sulfur content was decreased in the order of leaf blade+leaf sheath, stem and ear, and was higher in the low productive field than that of high productive field.

A 26 day experiment was conducted to determine the effects of feeding and starvation on the survival, morphology, and histology in chum salmon (Oncorhynchus keta) fry. We included three experimental groups: starved, fed, and initial. The survival and growth rates were lower in the starved group than in the fed group (P < 0.05). In the starved group, survival began to decline after 16 days, and all fish had died after 26 days. We determined the effects of starvation on the morphometric parameters using the truss and classical dimensions. The dimensions in the head region were larger in the starved group than in the initial and fed groups. In contrast, the truss dimensions of the fed group were larger than those of the initial and starved groups. Starvation reduced the heights of the hepatocyte nuclei and of the intestinal epithelium (P < 0.05). The starved group also showed atrophy of the digestive structures and shrinkage of the foregut and midgut. Starvation led to the degeneration and atrophy of the exocrine pancreas, in which the lumen was markedly diminished and the folds of mucosa were less apparent. The hepatocyte morphology in the starved group was abnormal compared with that of the initial and fed groups, with highly compact, irregularly shrunken nuclei. Melanomacrophages were randomly distributed in the kidneys of the starved group, and their abundance increased rapidly during the experiment. In contrast, neither the initial nor fed group had any melanomacrophages. These results suggest that the nutritional parameters used in this study are useful indices of nutritional status in chum salmon.

Poultry welfare has recently appeared as worldwide concern as well as Korea. The recent action plan for farm animal welfare introduced by the European Commission intends to expand the body of regulatory standards. In this context, many countries and/or organization are on the verge of establishing the most optimum poultry welfare standards. To establish the most optimum standards, comparative analysis of feeding regimen before and after welfare-bestowed environment need to be preceded. Most guidelines or standards for poultry welfare do not suggest the nutritional requirements and feeding system in detail, although it is deterimental especially for the farmer. This review intends to find scientific base to establish detailed welfare feeding guidelines. However, only limited research has been conducted in the view of actual poultry welfare. The results indicated the incidence of SDS, ascites, skeletal dysfunctions caused by fast growth rate in broiler, feather pecking and cannibalism in laying hen, and feed restriction in broiler breeder could be reduced by changing nutritional regimen and feeding strategies or both. The regimen and feeding strategies are certainly near to the direction that the poultry welfare ought to be in the right track. In this article, feeding and drinking guidelines in many standards as well as welfare feeding experiments have been reviewed and compared In the view of chicken productivity, welfare physiology and poultry health.
