This study was conducted to analyze the relations among nutritional knowledge, nutrional attitude, eating practice and total nutritional diagnosis and also to find the influencing factors of them. The survey was done during the period from April 1990 to June 1990 and the target population were Ewha Womans University students (freshmen and senior) of whom 1,354 peoples were surveyed. The summarized results are as follows ; 1. For the teaming environment, the percentage of completion on nutritional knowledge course was 28.6% and among them the department of foods and nutrition had the highest score(100.0%) and the next was dept. of medicine (53.4%). 2. To find the relation which the nutritional knowledge, nutritional attitude, eating practice and the total nutritional diagnosis influence on one another, the multiple correlation analysis was done. The attitude and the practice were highly correlated with total nutritional diagnosis, but the correlation between nutritional knowledge and total nutrional diagnosis was not significant. The correlation between the practice and nutritional knowledge which were positively and significantly correlated with attitude respectively was positive but not significant. 3. The difference which were analyzed by department, grade and completion on knowledge course on the nutritional knowledge, attitude, eating practice were significant (p<0.01) by ANOVA. 4. The significant variables on nutritional diagnosis are the eating practice points, the grade, the knowledge course, the breakfast and the attitude ($r^2=10.3%$) by multiple regression analysis. This study has the limitation that it did not consider the environmental factors of dietary life such as dietary culture, family environment, cultural habit. Therefore important points of these dietary studies are to extend to the practical nutritional education and dietary improvement for the national health not restricted to the local area or local population.

Serratia plymuthim A21-4 strongly inhibits the mycelial growth, zoospore formation, and cystospore germination of Phytophthor spp and Pythium species. The bacterial isolate produced antifungal substance and chitinase. The bacteria also enhanced to plant growth remarkably in low nutritional condition. The application of cell suspension of A21-4 to pepper seedlings in greenhouse experiments and soil drenching in farmer's field was proved successfully to control the phythophthora blight of pepper. For the effective control, however, relatively high density of cell number(10$\^$9/cfu/$m\ell$) is required. Density effect was similar in plant growth promoting activity of A21-4. Though this investigation we improved the problem with changes of culture condition of bacteria and some nutritional amendment.

The effects of environmental agents on health are great concern for all. It was recognized that each human has differential susceptibility to environmental effects. Susceptibility are changed by many factors includin gdevelopmpntal processes, genetic factors, nutritional stratus, preexisting disease conditions, life style and personal habits. Of all factors nutritional factors seem to be the area most modifiable. Consequently, It is an area that must be more thoroughly evaluated. In this paper, nutrient and environment interactions are reviewed briefly with published literatures. This paper deals with the influence of micronutrients(energy, protein and fat), Vitamins (vitamin 4, vitamin B-complex, vitamin C, vitamin D and vitamin I) and Minerals(calcium, iron, selenium, zinc and other minerls) on environmental effects. The role of arch nutrient was assessed in modifyine the expression of environmental pollutant toxicity with available litertures. In each nutrient section, the effect of environment was considered in following agents : heavy metals(lead, cadmium, mercury, silver and etc), inorganic agents(nitwits, sulfite, fluoride and etc), organic agents(benzene, carbon tatra-chloride, aflatoxin, auto dye, dialbrin etc), Irritant gas(ozone, carbon monooxide and etc), physical agents(X-irradiation, ultra violet, temperature and noise) and insectcides. The extent to which nutritional status modifies environmental effects 3nd its converse, how envirollments affects nutritional status is very complex. In deed, at the present time there are more than 50 chelnical/phycical agents that affect the nutrient metabolism and/or have their toxicity either directly diminished or enhanced by nutrients of those agents, small number of agents for each nutrients have sufficient evidence to warrant any reasonable degree of confidence in their hypothesized associtation. With these information at this present time it is hard to conclude that the recommended dietary allowance for each nutrient should be reconsidered.

The aim of this study was to investigate school dieticians' awareness of the necessity for nutritional education and job satisfaction via qualitative research. For this purpose, in-depth interviews were carried out with 10 school dieticians. Results revealed that all participants said that schools urgently need nutritional education, and dietary attitude and unbalanced eating habits were the most urgent matters to be addressed. They made various suggestions related to revitalization of nutritional education: turning dieticians into nutritional educators, improving awareness of teachers and parents, receiving training on appropriate teaching methods, and so on. In response to their tasks, they considered bargaining with vendors and examination foods as the most burdensome tasks. In response to questions about how participants were treated in their workplaces, all participants reported low job satisfaction due to excessive work, lack of promotion opportunities, and low salary. To improve this, participants recommended creating a task manual, strengthening their role as managers, increasing their salary, and so on. Therefore, institutional support is necessary for dieticians to efficiently handle their excessive workload. In addition, an educational environment where dieticians can effectively carry out nutritional education needs to be created.

Analysis of nutritional compositions of soybean sprouts cultivated with bamboo ash was carried out. Bamboo ash was utilized as sprouting water of soybeans and adjusted to 0.2, 0.6, 1.0, 1.4, 2.0, 6.0 and 10.0 g/L. Stem length and contents of isoflavone (daidzin, glycitin, genestin, daidzein, glycitein, and genestein) and vitamin C in soybean sprouts cultivated with 0.2 g/L were higher than those in soybean sprouts cultivated with only water. Potassium, magnesium, and calcium of all cultivation methods were detected in higher contents than others. In particular, potassium showed a high absorption rate in the soybean sprouts. The major amino acid was asparagine (616.05~849.15 mg/100 g, soybean eq.), and contents of lysine, leucine, and ornithine in soybean sprouts cultivated at 0.2 g/L were higher than those of methods by only water and addition of 6-benzylaminopurine. According to the results, soybean sprouts cultivated with 0.2 g/L of bamboo ash were effective for increasing nutritional compositions.

Animals are one of the important memberships of the food chain. The low-efficiency rule of nutrient transfer from one member to the next in the food chain determines the low efficiency of animal agriculture for human food. On the average, about 20% feed proteins and 15% feed energy can be converted into edible nutrients for humans. The rest proportion of feed nutrients is exposed to the environment. Environmental pollution, therefore, is inevitable as animal agriculture grows intensively and extensively. The over-loading of the environment by nutrients such as nitrogen, phosphorus from animal manure results in soil and water spoilage. The emission of gases like $CH_2$, $CO_2$, $SO_2$, NO, $NO_2$ by animals are one of the contributors for the acidification of the environment and global warming. The inefficient utilization of natural resources and the probable unsafety of animal products to human health are also a critical environmental issue. Improving the conversion efficiency of nutrients in the food chain is the fundamental strategy for solving environmental issues. Specifically in animal agriculture, the strategy includes the improvements of animal genotypes, nutritional and feeding management, animal health, housing systems and waste disposal programs. Animal nutrition science plays a unique and irreplaceable role in the control of nutrient input and output in either products or wastes. Several nutritional methods are proved to be effective in alleviating environmental pollution. A lot of nutritional issues, however, remain to be further researched for the science of animal nutrition to be a strong helper for sustainability of animal agriculture.

The study explores the impact of nutritional information on calorie prediction and purchase intent. Administered through self-report questionnaires, the research employs two types of stimuli to assess the influence of nutritional information. Hamburger set images, with or without accompanying nutritional details, were randomly presented to simulate the prevalent mobile app environment for fast-food delivery. Respondents were tasked with predicting calorie content and indicating purchase intent on a Likert 7-point scale. Results show a significant difference in calorie prediction based on the presence of nutritional labeling. While consumers expect positive health effects by estimating more exact calorie information with nutritional labeling, it doesn't significantly influence purchase intent. The study also examines consumer awareness and preferences regarding nutritional labeling policies, emphasizing the need for education and promotion. Most participants recognize the necessity of mandatory nutritional labeling in fast-food establishments, especially through delivery applications, to support healthier choices and prevent obesity.

To investigate whether phospholipase D (PLD, EC 3.1.4.4) plays a role in adaptive response of post-harvest fruit to environment, a PLD gene was firstly cloned from grape berry (Vitis Vinifera L. cv. Chardonnay) using RT-PCR and 3'- and 5'-RACE. The deduced amino acid sequence (809 residues) showed 84.7% identity with that of PLD from Ricinus communis. The secondary structures of this protein showed the characteristic C2 domain and two active sites of a phospholipid-metabolizing enzyme. The PLD activity and its expression in response to heat acclimation were then assayed. The results indicated PLD was significantly activated at enzyme activity, as well as accumulation of PLD mRNA and synthesis of new PLD protein during the early of heat acclimation, primary suggesting that the grape berry PLD may be involved in the heat response in post-harvest grape berry. This work offers an important basis for further investigating the mechanism of post-harvest fruit adaptation to environmental stresses.

Extensive studies have shown that breast milk is the best source of nutrition for infants, especially during the first six months, because it fulfills almost all of their nutritional needs. Among the many functional building blocks in breast milk, human milk oligosaccharides (HMOs) have been receiving more attention recently. Furthermore, it is the third most common group of compounds in human milk, and studies have demonstrated the health benefits it provides for infants, including improved nutritional status. HMOs were previously known as the 'bifidus factor' due to their 'bifidogenic' or prebiotic effects, which enabled the nourishment of the gastrointestinal microbiota. Healthy gastrointestinal microbiota are intestinal health substrates that increase nutrient absorption and reduce the incidence of diarrhea. In addition, HMOs, directly and indirectly, protect infants against infections and strengthen their immune system, leading to a positive energy balance and promoting normal growth. Non-modifiable factors, such as genetics, and modifiable factors (e.g., maternal health, diet, nutritional status, environment) can influence the HMO profile. This review provides an overview of the current understanding of how HMOs can contribute to the prevention and treatment of nutritional issues during exclusive breastfeeding.
