The purpose of this study is designing a daily diet according to the nutrition by using genetic algorithms. The ratio of the amount of nutrients needed for each individual is different. For example, people who want to lose, maintain or gain the weight need different amount of nutrition and ratio. In addition, the nutrition should be different between the age groups such as child, youth and senior. So, it is important for each person to individualize content of nutrition that they need not the nutritional standard table. Thus, in this study, by using the genetic algorithm, our study is about the program that can make a daily diet which is optimized for individual. The program has the information of main dish, soup and side dish that we entered before. And person who uses the program can see the daily diet which is optimized related by nutrition what the person entered before. Generally, it is really difficult to design a meal by considering all of the nutrition at home because there are a lot of things to be considered. Therefore, the goal of our study is to make the program what can make a balanced daily diet at home.

BACKGROUND/OBJECTIVES: Diet planning in childcare centers is difficult because of the required knowledge of nutrition and development as well as the high design complexity associated with large numbers of food items. Artificial intelligence (AI) is expected to provide diet-planning solutions via automatic and effective application of professional knowledge, addressing the complexity of optimal diet design. This study presents the results of the evaluation of the utility of AI-generated diets for children and provides related implications. MATERIALS/METHODS: We developed 2 AI solutions for children aged 3-5 yrs using a generative adversarial network (GAN) model and a reinforcement learning (RL) framework. After training these solutions to produce daily diet plans, experts evaluated the human- and AI-generated diets in 2 steps. RESULTS: In the evaluation of adequacy of nutrition, where experts were provided only with nutrient information and no food names, the proportion of strong positive responses to RL-generated diets was higher than that of the human- and GAN-generated diets (P < 0.001). In contrast, in terms of diet composition, the experts' responses to human-designed diets were more positive when experts were provided with food name information (i.e., composition information). CONCLUSIONS: To the best of our knowledge, this is the first study to demonstrate the development and evaluation of AI to support dietary planning for children. This study demonstrates the possibility of developing AI-assisted diet planning methods for children and highlights the importance of composition compliance in diet planning. Further integrative cooperation in the fields of nutrition, engineering, and medicine is needed to improve the suitability of our proposed AI solutions and benefit children's well-being by providing high-quality diet planning in terms of both compositional and nutritional criteria.

This study was to examine the effect of standards of selecting jeans and appearance management behavior on leisure lifestyle. Questionnaires were administered to 253 college students living in Deagu and Kyoungbuk. Data were analyzed by using frequency, factor analysis, regression analysis, t-test, and ${\chi}^2$-test. The findings are as follows. Factor structure of each concept appeared to be brand-valued, functionality valued and design-valued for standards of selecting jeans, diet management, exercise management, weight management and appearance satisfaction. Leisure lifestyle consisted of sports activity-type, sociality-type and self-management-type while value lifestyle consisted of active sociality-oriented, family-oriented and economic feasibility-oriented. There was a significant difference in brand-valued and design-valued of standards of selecting jeans and in frequency of wearing jeans male students showed higher than female students. The result of this study showed brand-valued, diet management, exercise management, weight management, and appearance satisfaction had significant effect on sports activity-type and design-valued and weight management had significant effect on sociality-type. Brand-valued affected self-management-type significantly and brand-valued, design-valued, diet management and appearance satisfaction had a significant effect on active sociality-oriented and brand-valued and diet management affected family-oriented.

The main objective of HACCP(Hazard analysis and critical control points) system is to provide a systematic preventive approach how to control the risks in food production process. Practically, the diet classification process performed at the one of the beginning steps of the HACCP system, makes an important role of determining food safety risks and how to control them in every control point according to the different risk level of the diet. In this paper, we propose an automatic diet classification method for HACCP system using XML(eXtensible Markup Language). In order to guarantee the diet classification accuracy, we design the XML schema and attributes represents the relationship of every diet and ingredients analysing the HACCP diet classification rules. Based on the XML schema and document generation method, we develope the proposed system as client and server model that implemented XML based HACCP diet information generation module and integrated HACCP information management modules, respectively. Moreover, we show the efficiency of the proposed system with experiment results describing the school food diet information as XML documents and parsing the diet information.

Two feeding trials were conducted to determine the effect of molasses feeding on the growth performances of bulls. In the first experiment, the straw of a control diet of straw and urea was replaced by molasses of 150 g ($M_{150}$) or $300g{\cdot}kg^{-1}$ ($M_{300}$). The three diets were fed ad libitum to three groups of bulls having five in each and the dietary responses were statistically analyzed in a simple design. The bulls were given fishmeal ($30g{\cdot}hd^{-1}{\cdot}d^{-1}$), wheat bran (0.5% of Liveweight, LW) and allowed grazing for $5hrs{\cdot}d^{-1}$. Molasses supplementation significantly (p < 0.001) increased the dry matter intake (DMI) of the bulls of $M_{150}$ (35.8g) and of $M_{300}$ (42.9g) than the control ($30.4g{\cdot}kg^{-0.75}$). The daily LW gain of the bulls of the $M_{150}$ (982g) was significantly (p < 0.05) higher than the bulls of the control or of the $M_{300}$ diet. In the second experiment, a control group of four bulls was fed a straw diet. Treatment two groups, having four bulls in each, were fed a mixed diet of Leucaena leucocephala and Setaria splendida(1:1, DM basis) with (LSM) and without (LS) molasses at $100g{\cdot}kg^{-1}$. The dietary responses were statistically analyzed in a simple design. The bulls of the LSM diet had significantly (p < 0.05) higher DMI, DM digestibility and LW gain ($128g{\cdot}kg^{-0.75}$, $663g{\cdot}kg^{-1}$ and $419g{\cdot}d^{-1}$, respectively) than the bulls of the LS diet ($98.3g{\cdot}kg^{-0.75}$, $583g{\cdot}kg^{-1}$ and $292g{\cdot}d^{-1}$, respectively). But the differences between the LSM and the control were nonsignificant. It may be concluded that molasses may be utilized as supplement to straw at $150g{\cdot}kg^{-1}$ or forages at $100g{\cdot}kg^{-1}$ diet for the profitable beef production from young growing bulls.

Two experiments were conducted to evaluate the effects of dietary Biotite V (BV) supplementation on growth performance, nutrients digestibility and fecal noxious gas content in finishing pigs. In Exp. 1, a total of eighty pigs (initial body weight 88.0${\pm}$1.35 kg) were used in a 35-d growth trial. Pigs were blocked by weight and allotted to five dietary treatments in a randomized complete block design. There were four pigs per pen and four pens per treatment. Dietary treatments included: 1) Control (CON; basal diet), 2) 200 mesh BV1.0 (basal diet+200 mesh Biotite V 1.0%), 3) 325 mesh BV1.0 (basal diet+325 mesh Biotite V 1.0%), 4) 200 mesh BV2.0 (basal diet+200 mesh Biotite V 2.0%) and 5) 325 mesh BV2.0 (basal diet+325 mesh Biotite V 2.0%). Through the entire experimental period, there were no significant differences in ADG, ADFI and gain/feed among the treatments (p>0.05). With the addition of Biotite V in diet, DM and N digestibilities were increased significantly (p<0.01). Also, Ca and P digestibilities tended to increase in pigs fed Biotite V supplemented diet (p<0.01) compared to pigs fed control diet. Supplementation of Biotite V in diet reduced the fecal $NH_3-N$ and volatile fatty acid (VFA) compared to CON treatment (p<0.01). In Exp. 2, a total of sixty four pigs (initial body weight 84.0${\pm}$1.05 kg) were used in a 35-d growth trial. Pigs were blocked by weight and allotted to four dietary treatments in a randomized complete block design. There were four pigs per pen and four pens per treatment. Dietary treatments included: 1) LP (low protein diet), 2) HP (high protein diet), 3) LP+BV (low protein diet+325 mesh Biotite V 1.0%) and 4) HP+BV (high protein diet+325 mesh Biotite V 1.0%). Through the entire experimental period, ADG and gain/feed tended to increase in HP and HP+BV treatments, however, there were no significant differences (p>0.05) among the treatments. With the addition of Biotite V in diets, digestibilities of nutrients (DM, N, Ca and P) were increased significantly (p<0.01). The addition of Biotite V in diets reduced the ammonia emissions in feces (p<0.01). Supplementation of Biotite V in diets also reduced the fecal propionic acid, butyric acid and acetic acid (p<0.01) compared to pigs fed diets without Biotite V. In conclusion, supplementation of Biotite V can increase nutrients digestibility and reduce fecal $NH_3-N$ and volatile fatty acid (VFA) concentrations in finishing pigs.

Objective: This study was conducted to evaluate the effects of feed processing and particle size on growth performance, nutrient digestibility, carcass characteristics, and gastric health in growing-finishing pigs. Methods: A total of 360 growing pigs (22.64±0.014 kg initial body weight [BW]) were allocated to 1 of 6 treatments with 6 replicates by BW and sex, and 10 pigs were housed in one pen in a randomized complete block design. The BW and feed intake were recorded to calculate growth performance. For the digestibility trial, a total of 24 barrows with an initial BW of 33.65±0.372 kg were split into 6 treatments with a completely randomized design. Dietary treatments were designed by a 2×3 factorial arrangement of treatments based on two main factors, particle size (600, 750, 900 ㎛) and feed form (mash and pellet) of diet. Experimental diets were formulated to contain the requirements of the NRC (2012). Results: The BW and average daily gain were not changed by dietary treatments, and the feed intake of finishing pigs (wks 6 to 12) was increased when the pigs were fed a mash diet (p<0.05). For the overall period, the feed efficiency of pigs was improved with the pellet diet (p<0.01) and reduced particle size (p<0.05). The pellet diet had effects on increasing crude fat digestibility (p<0.01) relative to a mash diet, but there was no considerable change in dry matter and crude protein digestibilities by dietary treatments. In the evaluation of gastric health, a trend for an increased incidence of keratinization in the esophageal region was observed as particle size decreased (p = 0.07). Conclusion: Feed efficiency could be improved by pellet diet and reduced particle size. Nutrient digestibility, carcass characteristics, and gastric health were not affected by feed form, and particle size ranged from 600 to 900 ㎛.

Selenium (Se) apparent absorption and retention in sheep as influenced by diets differing in protein content through soybean meal supplementation was studied. A $3{\times}3$ Latin square design was used with three Japanese Corriedale wethers (45 kg average body weight), three periods, and three dietary treatments. In each period, 7 d dietary adjustment was followed by 5 d total collection of urine and feces. The three dietary treatments were : Diet 1, without soybean meal supplementation (14% crude protein, CP); Diet 2, with 10% soybean meal supplementation (16.5% CP); and Diet 3, with 20% soybean meal supplementation (19% CP). All the diets had a Se supplementation in the form of sodium selenite at 0.2 mg Se/kg dietary DM. The dietary DM intake of the animals was 2% of their body weight. No significant differences were obtained among the three dietary treatments of the Se balance of the animals. However, as percent of Se intake, only urinary Se concentration of Diet 3 was markedly lower (p < 0.05) than the other diets. Fecal Se as percent of Se intake followed the trend of Diet 3> Diet 2 > Diet 1 resulting a Se absorbed as percent of Se intake of 58.9%, 62.3% and 68.2% for Diets 3, 2 and 1, respectively but their differences among each other were insignificant. No significant differences that were observed either on Se retained as percent of intake (Diet 1, 48.2%; Diet 2, 45.2%; Diet 3, 46.0%) or Se retained as percent of Se absorbed (Diet 1, 70.7%; Diet 2, 72.4%; Diet 3, 77.9%). Significant correlation coefficients among the various measures of Se utilization were also observed. Regression analysis showed the following equation: Y = 93.8 - 1.86X (p <0.05, $r^{2}=0.48$), where Y is the Se absorbed as percent of Se intake (%) and X is the dietary protein content (%). This study concludes that Se requirement in sheep is greater when dietary protein content is high.
