The nutritional worth of Phalaris minor seeds was assessed in comparison to conventional cereal grains like maize and wheat. P. minor seeds had higher total ash and cell wall constituents as compared to wheat and maize grains. The CP content of P. minor was comparable to wheat grains but higher than maize grains. The in vitro studies revealed that the net gas production and availability of ME from P. minor was comparable to that of maize but the digestibility of nutrients was significantly (p<0.05) lower than that of conventional cereal grains. The digestion kinetic parameters for DM and CP revealed that P. minor had the highest (p<0.05) soluble fraction (a) followed by wheat and maize. Reverse trend was observed for insoluble but potentially degradable fraction (b). The effective and true DM and CP degradability was significantly (p<0.05) higher in wheat grains followed by that in P. minor and maize grains. The digestibility of OM and NDF was not affected by replacing cereal grains in concentrate mixture with P. minor seeds up to 75 per cent level. But the availability of ME from concentrate mixtures was comparable to control only up to 50% level of replacement. Replacement of cereal grains with P. minor did not affect the rapidly soluble fraction and insoluble but potentially degradable fraction of concentrate mixture containing P. minor up to 75 per cent, but it was depressed significantly at 100% replacement level. The effective and true degradability of DM of concentrate mixtures containing P. minor from 50 to 100 per cent was comparable to that of conventional concentrate mixture (CCM). The wheat based concentrate mixtures showed higher net gas production (208 vs. 201 ml/g DM/24 h), digestibility of nutrients and ME availability (9.64 vs. 9.54 MJ/kg DM) as compared to maize based concentrate mixture. The wheat based concentrate mixture had significantly (p<0.05) higher rumen undegradable fraction and effective degradability. The data conclusively revealed that conventional cereal grains could be replaced with P.minor seeds up to 75 per cent without affecting the availability of nutrients.

The present study was designed to analyze the relationship of dietary behavior change and nutrient intake status owing to a depression degree for 143 people over 65 years old living in Echeong and Hansan islands area, South Korea. The depression degree was classified into non depression, minor depression and depressive disorder groups using. The Center for Epidemiological Studies-Depression (CES-D) scale for 143 subjects. The results are as follows; the depression degree significantly made differences according to sex (p<.001), marital status (p<.05), self-related economic status (p<.001) and living expenses (p<.05). The stage of dietary behavior according to the depression degree was as follows; the non depression group was 57.6%, the minor group was 46.8% and the depressive disorder group was 27.1% of the subjects. The intake frequency of the cereal group (p<.05) and fruit group (p<.01) was significantly different among food group intake status owing to the depression degree. Mean adequacy ratio(MAR)[13], MAR[10], and MAR[4] of the depressive disorder group were significantly lower than that of the non depression and minor depression groups. Each average of MAR[13], MAR[10], and MAR[4] for the subjects were $0.68{\pm}0.2$, $0.67{\pm}0.2$, and $0.55{\pm}0.2$. Concerned about the nutrients over 1.0 index of nutritional quality(INQ) 8 nutrients of protein, Phosphorous, iron, zinc, vitamin A, vitamin $B_6$, niacin and vitamin C belonged to the non depression group. Additionally, 6 nutrients of protein, Phosphorous, iron, zinc, vitamin $B_6$ and niacin were included for minor depression and depressive disorder groups.

Three black rices(Suwon 415, Iksan 427 and Sanghaehyanghyeolla) harvested in Korea were examined in their pasting characteristics, and minor nutrients(vitamins and minerals) in comparison to those of a brown rice (Dongjinbyo), whereas Iksan 427 and Sanghaehyanghyeolla were waxy rices(0.4 and 0.6%, respectively). Iksan 427 and Sanghaehyanghyeolla showed similar viscosity pattern with significantly low pasting temperatures and viscosity. Brown rice showed higher pasting viscosity and pasting temperature than black rices, and its viscosity pattern was similar to Suwon 415. Brown rice and Suwon 415 displayed higher hardness but lower adhesiveness of their gels. Black rices contained more non-carbohydrate components and dietary fiber than brown rice. From the amino acid analysis, black rices contained more acid amino acids (aspartic and glutamic acids) than brown rice. Among the black rices, Suwon 415 had the highest content of total essential amino acids(4.3%). Black rices also contained higher amounts of vitamin B complexes (thiamin, riboflavin and niacin) and minerals(K, Mg and Ca) than brown rice. Sanghaehyanghyeolla showed an exceptionally high amount of Ca (12mg%).

This study concerns the nutritional status of food in a lunch-box and the school lunch program provided for Dong Duck Elementary School Pupils in Daegu. Two hundred andsix pupils were randomly selected as a sample. The nutrients contained in a lunch-box and school lunch menu were analyzed according to the Food Composition Table. Nutrients and cost of the Dong Duck Elementary School Lunch were compared to the average nutrient contents of food in a lunch-box of o pupil. In addition, comparisons between the Recommended Daily Allowances of nutrients for Korean children aged from 9 to 11 (4th, 5th, and 6th grade) and that of the contained nutrients in the average lunch-box were conducted. The average nutrients contained in the lunch-box compared with the Recommended Daily Allowances are: Calorie 77.41% (542.60ca1), Protein 73.60% (16.93gr), Fat 33.95% (3.95gr), Calcium 27.85% (111.39mg), Ferret 80.30% (2.65mg), Vitamin A 10.09% (100.93 I.U.), Vitamin Bl 70.27% (0.27mg), Vitamin B2 88.37% (0.38mg), Vitamin C 15.40% (3.45mg). All of the nutrients in the lunch-box fall far below the Recommended Daily Allowances for the 9-11 age group. The average nutrients of staple food in the lunch-box compared with the side-dishes were found to contain Calorie 90.80%, Protein 50.32%, Fat 58.27%, Calcium 37.07 %, Ferret 53.96%, Vitamin A 0.0028%, Vitamin B1 78.11%, Vitamin B2 21.09%. The nutrients of food contained in the Dong Duck Elementary School Lunch Program compared with the Recommended Daily Allowances were: 1. The Protein, Fat, Ferret, Vitamin B1 and Vitamin B2 content was generally satisfactory. 2. Calcuim, Vitamin A and Vitamin C were lower than the Recommended Daily Allowances. 3. The Calorie content was generally lower for the 9-11 age group. The per pupil cost of the lunch-box was 41.87 won which includes the cost of staple food 16.92 won and side-dishes 24.95 won, whereas the school lune Provided by Dong Duck Elementary School Costs 35 won per pupil. Questionnaires were sent to four hundred parents (through their children) to find out their attitude toward the school lunch program. 390(97.50%) of them were returned and 7 of them dia not answer at all. Therefore, these were eliminated from the samlpe. Among 185 parents whose children were eating the school lunch; 172 parents (92.97% ) would pay 40 won for the proposed new school lunch program whereas only 13 parents (7.03%) did not want it. Among 198 parents whose children were not having the school lunch, 58 parents (29.29%) would agree to have the lunch for their children at the cost of 35 won with the proposed new school lunch program equivalent to 40 won. 126 parents (63.63%) could not agree to have their children being the school lunch because of their financial difficulty (74 parents 58.72%). The rest of parents (52 parents 41.28%) raised other reasons which were minor problems. Among the tatal of 383 parents, 309 parents (80.68%) would agree to gave school lunch for their children if the cost of the proposed new school lunch program would be 35 won to 40 won and if minor problems concerning the school lunch program are solved. Sixty parents (15.66% ) raised questions about the school lunch program concerning sanitary problems, taste of bread, and the quantity of lunch. Among 383 parents, 358 parents answered and 25 parents did not. When school officer asked if the parents would help during the school lunch hour, 101 parents indicated they could not help at all, but 177 parents, replied they could help. Among 177 parents, 40 parents of them could share their time from one or two hours everyday except Saturday and 107 parents could serve 1 to 3 days per week. Through this study, it is evident that further investigation should be done of the school lunch program which can be provided 35 won with the proposed new school lunch program. The parents participation in the school lunch program would be improved the understanding between school and parents as well as insure better nutrition and sanitation for the children.

This study was conducted to determine the protein content, cell wall fractions, and mineral concentrations of some minor plant species collected for one year in pastures grazed by goats in the Philippines. An assessment of nutrient variability and a comparison of forage protein and mineral concentrations to the critical value of protein and minerals based on animal needs were also studied. The plant species were the following: grasses(Axonopus compressus, Eleusine indica, Rottboellia exaltata); legumes (Aeschynomene indica, Calopogonium muconoides, Desmodium tortousum); and herbs (Corchorus olitorius, Ipomea aquatica, Sida acuta, Synedrella nodiflora). The two seasons (dry and wet) were subdivided into Dry-1 (December to February, 132 mm total rainfall), Dry-2 (March to May, 25 mm total rainfall), Wet-1 (June to August, 1,138 mm total rainfall), and Wet-2 (September to November, 1,118 mm total rainfall). Results showed that significant differences were obtained on various nutrient fractions including those mineral concentrations across species. Across season, acid detergent lignin (ADL) had higher (p < 0.05) value at Dry-1. Legumes and herbs were higher in crude protein (CP) especially Sida acuta. Grasses showed the highest neutral detergent fiber (NDF) and acid detergent fiber (ADF) with the addition of Sida nodiflora (herb) for it contained high NDF. Aeschynomene indica contained the highest amount of ADL and the herbs (Ipomea aquatica and Sida acuta) had exceptionally high concentration of minerals. Coefficient variation of the various nutrient values ranged from 27.3 to 136.7%. Some forage minerals appeared to be deficient (sodium, phosphorus and copper) or excess (molybdenum) for the whole or part of the year. This study shows that some minor plant species could extend the range of concentration of some nutrients (i.e., CP and minerals) beyond that normally found in conventional pasture species.

The object of this study was to determine long-term temporal and spatial patterns of nutrients (nitrogen and phosphorus), suspended solids, and chlorophyll (Chl) in Chungju Reservoir, based on the dataset of 1992 - 2013, and then to develop the empirical models of nutrient-Chl for predicting the eutrophication of the reservoir. Concentrations of total nitrogen (TN) and total phosphorus (TP) were largely affected by an intensity of Asian monsoon and the longitudinal structure of riverine (Rz), transition (Tz), and lacustrine zone (Lz). This system was nitrogen-rich system and phosphorus contents in the water were relatively low, implying a P-limiting system. Regression analysis for empirical model, however, showed that Chl had a weak linear relation with TP or TN, and this was mainly associated with turbid, and nutrient-rich inflows in the system. The weak relation was associated with non-algal light attenuation coefficients (Kna), which is inversely related water residence time. Thus, values of Chl had negative functional relation (R² = 0.25, p < 0.001) with nonalgal light attenuation. Thus, the low chlorophyll at a given TP indicated a light-limiting for phytoplankton growth and total suspended solids (TSS) was highly correlated (R² = 0.94, p < 0.001) with non-algal light attenuation. The relations of Trophic State Index (TSI) indicated that phosphorus limitation was weak [TSI (Chl) - TSI (TP) < 0; TSI (SD) - TSI (Chl) > 0] and the effects of zooplankton grazing were also minor [TSI (Chl) - TSI (TP) > 0; TSI (SD) - TSI (Chl) > 0].

In reviewing of the literature concerning agronomic practices on intensive pasture establishment the following suggestions were made : (1) The seedbed preparation should be involved physical manipulation of the soil tilth and consolidation of the soil by harrows and heavy roller. (2) In terms of methods of sowing, drilling favours the first and broadcasting the second however, the apparent superiority of band sowing over the above conventional methods is to reduce the direct toxic chemical effects from fertilizers to germinating seeds. (3) The most satisfactory seeding depth for grasses and legumes is commonly agreed to be approximately 1.3cm and seeding depth greater than 2.5cm seems to be generally detrimental. (4) Autumn and spring are most common sowing periods for grasses and legumes, however, early autumn being the most generally favoured, particularly in areas not subject to severe winter kill. (5) Select nurse crop species or cultivars which make Bess demands on light, nutrients and water, and lower seed rates should be used. (6) Seeding mixtures should be simple rather than complex and aggressive species should be included to a minor extent.

The term, "food safety", has traditionally been viewed as a practical science aimed at assuring the prevention acute illnesses caused by biological microorganisms, and only to a minor extent, chronic diseases cause by chronic low level exposures to natural and synthetic chemicals or pollutants. "food safety" meant to prevent microbiological agents/toxins in/on foods, due to contamination any where from "farm to Fork", from causing acute health effects, especially to the young, immune-compromised, genetically-predisposed and elderly. However, today a broader view must also include the fact that diet, perse (nutrients, vitamins/minerals, calories), as well as low level toxins and pollutant or supplemented synthetic chemicals, can alter gene expressions of stem/progenitor/terminally-differentiated cells, leading to chronic inflammation and other mal-functions that could lead to diseases such as cancer, diabetes, atherogenesis and possibly reproductive and neurological disorders. Understanding of the mechanisms by which natural or synthetic chemical toxins/toxicants, in/on food, interact with the pathogenesis of acute and chronic diseases, should lead to a "systems" approach to "food safety". Clearly, the interactions of diet/food with the genetic background, gender, and developmental state of the individual, together with (a) interactions of other endogenous/exogenous chemicals/drugs; (b) the specific biology of the cells being affected; (c) the mechanisms by which the presence or absence of toxins/toxicants and nutrients work to cause toxicities; and (d) how those mechanisms affect the pathogenesis of acute and/or chronic diseases, must be integrated into a "system" approach. Mechanisms of how toxins/toxicants cause cellular toxicities, such as mutagenesis; cytotoxicity and altered gene expression, must take into account (a) irreversible or reversal changes caused by these toxins or toxicants; (b)concepts of thresholds or no-thresholds of action; and (c) concepts of differential effects on stem cells, progenitor cells and terminally differentiated cells in different organs. This brief Commentary tries to illustrate this complex interaction between what is on/in foods with one disease, namely cancer. Since the understanding of cancer, while still incomplete, can shed light on the multiple ways that toxins/toxicants, as well as dietary modulation of nutrients/vitamins/metals/ calories, can either enhance or reduce the risk to cancer. In particular, diets that alter the embryo-fetal micro-environment might dramatically alter disease formation later in life. In effect "food safety" can not be assessed without understanding how food could be 'toxic', or how that mechanism of toxicity interacts with the pathogenesis of any disease.

To determine food preferences and nutrients intake of nursery school children, 199 children, ages 1 to 6 years, were assessed with a structured questionnaire completed by their mothers. The questionnaire included questions related to dietary habits, mother's interest in the child's health, family history of diseases, etc. The nutrients intake was measured by 24-hour recall method. Children's weight and height were measured by trained investigators on the same day. For analysis purposes, the subjects were grouped into underweight, normal and overweight groups based on the z-score of weight for height. Only 58.3% of the subjects were grouped into the normal weight group. On the other hand, 19.1% were in the underweight group and 22.6% were in the overweight group. Forty four percent of them showed unbalanced dietary habits such as preference for picky foods, 40.0% of them disliked vegetables, and 46.7% disliked minor grains other than rice. Children in the underweight group showed a higher score of inappropriate dietary habits compared to those of normal or obese groups. The level of nutrients intake of the subjects was higher than the Korean RDA value in general, except for Ca, calories, and Zn. However, 87.4% of the children showed a higher intake level than 125% of KRDA in protein, and 18.2% and 41.4% of them showed a lower intake level than 75% of KRDA in Fe and Ca, respectively. Children in the underweight group showed a higher percentage of eating less than 75% KRDA in niacin compared to those of the normal or overweight group (p<0.05) and we found a similar tendency in Fe, Zn and Vitamin $B_1$ intake.
