  • This study was reviewed databases and outcomes of national/international off-line and on-line(Internet) nutrition softwares to identify the present conditions of nutrition softwares, and investigated user's needs and determine which component should be included in nutrition software. The most frequently used databases for the national programs were the food composition table provided from the National Rural Living Science Institution in Rural Development Administration and the food composition table and the nutrient contents of foods provided from the Korean Nutrition Society. For international programs, the food composition table from the USDA was commonly used. The analysed outcomes included the degree of obesity, nutrient analysis and nutrient intake compared with RDA, food intake from each by food group, food habits and the frequency of food consumption. As to the result of needs assessment for the Internet nutrition softwares, it was suggested that the needs of the Internet nutrition softwares were high because most of the respondents replied that 3-point('it is needed') or 4-point('it is necessary') on 4-points likert scale. As to the databases, the needs of 'food composition analysis' and 'the suggestion of the Korean RDA' were high. For the basic information for foods, the respondents replied that 'the classification of foods', 'foods codes', 'the amount of ingredients' and 'nutrient analysis' should be included. The needs of 'nutrient analysis of meal', 'diet therapy' and 'meal plan by caloric requirements' were high. As for utilizing the Internet meal planning programs, the respondents replied that 'it should be easy to use' most and demand for 'data saving and the saved data should be usable later' and 'meal planning education tools' were high. In conclusion, the Internet nutrition software that satisfies various needs of users should be developed for policy making that promote public health, nutritional care and self-supporting of foods.

  • Depression is a kind of mood disorder characterized by decline in motivation, interest, attention, mental activity, and appetite. Although depression is caused by a variety of causes, including genetic, endocrine and environmental stress, mild depression has been reported to improve with diet. Therefore, various type of food sources including functional and nutritional supplement are required to treat the depressive patients. Cheese contains bioactive peptides that have beneficial effects on host health. In particular, Jersey milk has been reported to contain higher solids than does Holstein milk. This study investigated the effects of Gouda cheese from Jersey and Holstein milk on chronic, unpredictable, mildly stressed (CUMS) mice. Here, spontaneous alterations in cheese-fed stressed mice were noted to be effectively recovered with statistical significance regardless cow species. Interestingly, for the analysis of fecal microbiota, Bacteroidetes were noted to increase with a reduction in Firmicutes at the phylum level with Jersey cheese. Taken together, we suggest that cheese intake provided a beneficial effect on stressed mice in recovering recognition ability. In particular, changes in internal microbiota were observed, suggesting that the bioactive ingredients in cheese act as improvement agents with respect to mood and brain function.

  • This study investigated the effects of feeding mulberry leaf extracts on lipid composition in rats fed high cholesterol diets. An initial 30-person sensory evaluation of preparations containing various concentrations of mulberry leaf extract showed that a preparation containing 9% mulberry leaf extracts was the most highly preferred. In addition, subsidiary materials of pine needle extracts and mugwort extracts were added to weaken the unpleasant smell of mulberry leaf extract A preparation containing 9% mulberry leaf extract with 3% mugwort extract and 7% pine needle extract was given highest preference scores by the 30-person panel. When comparing the functional ingredients contents of the various preparations of mulberry leaf extracts, such as GABA, DNJ and flavonoids, no significant differences were found as a result of adding subsidiary materials (pine needle and mugwort extracts). Sprague-Dawley male rats weighing l00$\pm$10g were randomly assigned to one normal diet group, and to four high cholesterol diet groups containing 1% cholesterol, to elucidate the functionality of the mulberry leaf extract The four high cholesterol diet groups were classified into: a mulberry leaf extract diet group free of subsidiary materials (EB group); a mulberry extract diet group with pine needle extracts (EP group); a mulberry leaf extract diet group with mugwort extracts (EM group); and a control group (HC group). The mulberry leaf extracts were provided as drinking water; the diet and water were fed ad libitum. Hepatic cholesterol and triglyceride levels were higher, by 279% to 475%, in the high cholesterol groups compared to the normal diet groups, but were significantly lower in the three groups supplied with mulberry leaf extracts, compared with the high cholesterol control. There were no changes in functionality of the mulberry leaf extract preparations due to the addition of subsidiary materials. In conclusion, preparations of mulberry leaf extracts were shown to improve lipid metabolism in rats fed a high cholesterol diet, by reducing hepatic and plasma triglyceride and cholesterol levels. Also human palatability of the mulberry leaf preparation was improved by adding subsidiary materials such as pine needle and mugwort extracts.

  • To create a personal menu, there are a number of considerations. Personal menus are different depending on the dietary therapy for disease, diet for weight control. In addition, the menu you choose, depending on the personal preference and the season, the weather, current personal feelings may differ. An individual should expect to recommend a balanced diet, taking nutritional status just for health care. In this paper, we propose a personalized menu recommendations System framework to meet such needs. To recommend menus the system receives data of the body's individual circumstances, ingredients situation, environmental conditions, psychological condition, emotional condition and provides a recommended menu by performing the inference using the ontology generated from external application systems. In order to provide such services, Internet of Things (IoT) environment should be the foundation. In this paper, we propose a personalized diet recommendation system framework in the IoT standardization environment that has oneM2M common service platform.

  • The principal objective of this study was to determine the available components in different varieties of Discorea spp. The Discorea spp. samples were divided into three groups by variety. The three groups were divided into Jangma(D. batatas Decaisne), Danma(D. japonica Decaisne), and Doonggunma(D. opposita Thumb), and then assessed with regard to the content of proximate compositions, minerals, sugars, crude saponin, and diosgenin. No substantial differences were noted to exist among samples in terms of carbohydrate and crude protein contents. The crude lipid contents were detected in the following order : Danma(D. japonica Decaisne, $0.71{\pm}0.15%$) > Jangma(D. batatas Decaisne, $0.65{\pm}10.12%$) > Doonggunma (D. opposita Thumb, $0.49{\pm}0.10%$). The Danma(D. japonica Decaisne) samples were determined to harbor the highest K($2.07{\pm}0.91%$), Ca($0.21{\pm}0.12%$), Fe($110.7{\pm}0.0$ mg/kg), Mn($20.6{\pm}3.4$ mg/kg) and Zn($31.2{\pm}3.9$ mg/kg) contents among all tested samples. The predominant sugar components in all samples were mannose($70.7{\pm}1.3{\sim}80.5{\pm}1.5%$), glucose($18.2{\pm}1.2{\sim}28.3{\pm}2.5%$) and sucrose($60.3{\pm}3.7{\sim}83.6{\pm}6.5%$). The crude saponin and diosgenin contents for Jangma(D. batatas Decaisne), Danma(D. japonica Decaisne) and Doonggunma(D. opposita Thumb) varieties were : $1.7{\pm}0.4%$, $3.9{\pm}0.8%$ and $3.2{\pm}0.7%$, and $13.59{\pm}1.74$ mg/g, $14.25{\pm}1.60$ mg/g and $18.00{\pm}1.92$ mg/g, respectively.

  • Ostrich farming is a developing industry in most countries in the world, with farm profitability being largely dependent on the quality of the products, especially skins and meat. To produce quality products, it is essential to ensure that nutrient supply matches the nutrient requirements of ostriches during their growth. To achieve this, information on feed utilisation efficiency and nutrient requirements of ostriches at different maturity stages is required. In South Africa, a number of experiments were carried out to assess the nutritive value of feed and to define the nutrient requirement of ostriches. These data were derived from limited number of birds and the direct application of the results to ostrich farming in Australia and other countries is questionable due to the difference in environment and feed resources. Initially ostrich farmers used data from poultry as a guideline for feed formulation, but in recent years more data has become available for ostriches. Ostriches have a better feed utilisation efficiency and a larger capacity of using high fibre feeds such as pastures than poultry. This review revealed that there are a number of areas there further nutritional research and development is required to ensure the ostriches are provided suitable diets to maximise farm profitability. These include the assessment of the nutritive value of feed ingredients for ostrich chicks and adult birds, the determination of nutrient requirements of ostriches under different farming systems, the development of ostrich diet for producing specific product, and grazing management strategies of ostriches in a crop-pasture rotation system.

  • Soybean meal was fermented by Aspergillus usami in order to reduce phytate content. Aflatoxin B1 was not detected in the fermented soybean meal. The contents of crude protein, crude fiber, ether extract and crude ash were slightly increased following fermentation with a concomitant reduction in nitrogen free extract. Though the fermentation partly degraded proteins in the soybean meal, there was small difference in amino acid composition between the soybean meal and the fermented soybean meal. The results showed that the fermentation did not affect nutritional value of protein in soybean meal. Approximately 55% of phosphorus extracted by trichloroacetic acid was inositol hexaphosphate (phytate) in the soybean meal. The content of inositol tetra to hexaphosphates was not detected in the fermented soybean meal. These results indicated that the fermentation almost completely eliminated phytate in soybean meal. Phytase activity was not detected in the unfermented soybean meal. However, the enzyme activity in the fermented soybean meal was 167.7 U/g. When the fermented soybean meal in supplemented in formula feeds, phytase in the fermented soybean meal might partly degrade the phytate in other ingredients in the digestive tract. The fermented soybean meal is possibly used as a phytate-free protein source of feed, which contains high available phosphorus.

  • This study compared the nutritional value of canola (B. napa) and mustard (B. hirta) press cakes obtained from the biodiesel industry as ingredients for use in diets fed to broiler chickens. A total of 210, one-day old, male broiler chicks were randomly assigned to one of seven dietary treatments. The control diet was based on wheat and soybean meal and contained 15% canola meal. For the experimental diets, 5, 10 or 15% of the canola meal was replaced with an equal amount of either canola or mustard biodiesel press cake. Dry matter and neutral detergent fiber digestibility were significantly higher for birds fed diets containing either canola or mustard biodiesel press cake compared with canola meal. Dry matter and neutral detergent fiber digestibility of the canola biodiesel press cakes was higher than the mustard biodiesel press cakes. Ether extract digestibility and nitrogen retention were significantly higher for birds fed canola biodiesel press cake compared with canola meal and mustard biodiesel press cake. Body weight gain and feed intake did not differ between birds fed canola or mustard biodiesel press cake and canola meal. In addition, there was no significant difference in body weight gain or feed intake between birds fed diets containing canola or mustard biodiesel press cake. Feed conversion was significantly improved for birds fed either canola or mustard biodiesel press cake compared with canola meal. Mortality was unaffected by treatment. Since the performance of broilers fed canola biodiesel press cakes was essentially the same as that of broilers fed canola meal, it is difficult to justify a premium to be paid for canola biodiesel press cake over that paid for canola meal. In addition, there was no difference in the performance of broilers fed biodiesel press cake obtained from canola or mustard seed. As mustard seeds are generally available at a lower price than canola seed, there may be some incentive to use mustard rather than canola seed for producing biodiesel press cake for use in poultry production.

  • Food/nutrition related views, beliefs, attitudes, and behaviors were investigated for three hundred randomly selected men and women, aged 20-60 years, residing in Seoul metropolitan area. Food/nutrition views, attitudes, and beliefs were found to vary greatly between groups of different age, sex, education and income level. Adults of 20-35 years of age showed significantly less strong views about keeping traditional food habits, while exhibiting a significantly high level of acceptance towards the use of convenience foods as compared to the adults aged 36 years or older. Food safety was found to be a major concern to most of the subjects accounting 69.7% for pesticides residues in fresh produce items, 94.7% for food additives in processed food, and 56.3% for food poisoning in foods eaten outside of the home. Male adults aged 45 years or older showed a strong tendency to rely on a few promotional food products for the maintenance of their health and for them the development and implementation of a sensible feed nutritin/health education program including a way to avoid nutrition quackery might be beneficial. Eighty percent of the subjects were found to read food labels with higher rates shown among young adults and females. Due to the virtual absence of nutrition labeling however, the percentage of subjects who idicated that they are looking for the information on nutrient content was low (<10%) compared to the rates for other informations such as date of manufacture(80.2%), expiration data(55.8%), ingredients(40.9), and additives(40.9%). Ninety one percent of the subjects indicated that they would like to see the sources for nutrition label the nutritional value of the foods. The top five most frequently (68.3%), food packages(50.7%), and radio(43.3%). Health professionals such as physicians, nurses, and nutritionists/dietitians were utilized less frequently as sources of nutrition information than lay sources, with reported rate of only 38%, 22%, and 0.7%, respectively. These results collectively suggest that strategies are to be developed to provide accurate nutrition information to adults.

  • Natto, Traditional Japanese food fermented by Bacillus Natto, has been well known for a good nutritional food. However it has particular flavor, so most Koreans are not fond of it. That is the reason why, garlic(2%) and ginseng(2%) were added to make Natto, acceptable to Koreans. General soybean Natto($S_1$), 2% garlic Natto($S_2$), 2% ginseng Natto($S_3$) and blacksoybean Natto($S_4$) were prepared. The proximate composition revealed the most moisture content in $S_2$among the all samples. The most crude protein, crude fat and ash were found in $S_4$. The non-fibrous and fiber contents were the most in $S_1$and $S_3$. In the texture characteristics, hardness and gumminess were the highest in $S_4$. The highest springness and cohesiveness were found in $S_1$. Adhesiveness and chewing were the best in $S_2$and $S_3$. The minerals composition revealed the most calcium content in $S_3$among the all samples. Fatty acid compositions were mainly consisted of linoleic acid(46.91~48.47%). In the sensory evaluation, $S_3$showed the best preference, appearance and color. In the aspects of taste and texture, $S_4$was mostly preferred. Flavor and viscosity of $S_2$were the best among the all samples. The general soybean Natto($S_1$) without any addition showed low values in most examinations and tests. In the sensory evaluation, $S_3$has the best overall acceptability among the all experimental Nattos.
