This study proposes a content-based recommendation algorithm (NRA) for pet food. The proposed algorithm tries to recommend appropriate or inappropriate feed by using collective intelligence based on user experience and prior knowledge of experts. Based on the physical and health status of the dogs, this study suggests what kind of nutrients are necessary for the dogs and the most recommended pet food containing these nutrients. Performance evaluation was performed in terms of recall, precision, F1 and AUC. As a result of the performance evaluation, the AUC and F1 value of the proposed NRA was 15% and 42% higher than that of the baseline model, respectively. In addition, the performance of NRA is shown higher for recommendation of normal dogs than disease dogs.

The purpose of this study was quantitative and qualitative contents analysis of food and nutrition section in middle school textbooks of home economics, physical education and science. As a quantitative approach numbers of sentence lines tables, figures, photos, activities, and exercises were counted. As a qualitative approach, types of explanations were categorized by 7 criteria, and commons and differences of the contents of those subjects were compared. The conclusions of this study were summarized as follows: 1) Contents of food and nutrition section were divided into nutrients. water. energy, food groups, and nutritional problems. When average sentence lines of each were compared, those of nutrients were the longest in all 3 subjects. 2) When compared the numbers of tables, figures, and photos in 3 subjects of textbooks, there were more figures in home economics and science, and more tables in physical education. 3) There were more activities and exercises in home economics an science than in physical education. 4) The D(sentences with table) or E type(sentences with figure) was adapted for the explanation of nutrients functions, recommended dietary allowance, food sources, food groups, eating habits, and weight control in home economics: nutritions functions and energy metabolism in physical education : and digestion, body constituents, energy metabolism, and detection of nutrients in science. 5) Contents about classification and functions of nutrients. food sources deficiency water, energy contents of nutrients and obesity were shown in all 3 subjects. Food groups and eating habits were explained in detail in home economics whereas digestion of nutrients in the digestive tracts were explained in detail in science. Recommended dietary allowance for Koreans and basic food groups revised in 1995 were presented in home economics, whereas those revised in 1989 were presented in physical education. To avoid confusion, recommended dietary allowance for Koreans and food groups presented in physical education tex should be updated.

This experiment was conducted for 4 weeks to compare the feeding values of dried meal of Russian Comfrey and Kale as green feeds with Acacia leaf meal and Ladino clover meal, and to investigate the effects of feeding these on the total cholesterol in blood serum and liver fat content. Seventy-five male chicks of Single Comb White Leghorn were allotted into 5 treatments. Fifteen birds in each treatment were received Russian Comfrey meal, Kale meal, Acasia leaf meal, Ladino clover meal or no dried meal, respectively. The results obtained are summarized as follows: 1. No significant differences were recognized between the treatments and control in the growth rate, feed consumption, feed efficiency, utilization of nutrients, nitrogen retention and metabolizable energy value. 2. Carotene content in Russian Comfrey and Kale has been decreased as the growing stage advanced, and the leaves of both vegetable contained significantly (p<0.01) more carotene than that in stems. Vitamin C content of leaves was also signifcantly (p<0.01) higher than that in stems, however, vitamin C content has been increased as the growing stage advanced. 3. Toltal cholesterol content in blood serum of the chickens fed the Acacia leaf meal or Russian Comfrey meal was significantly (p<0.05) lower than Ladino clover meal fed group or those received no green feeds. Kale seems to decrease cholesterol content a little. Above results indicated that Acacia leaf and Russian Comfrey might contain certain substances that would depressing the cholesterol content. 4. No significant differences in the liver fat were discovered among the treatment but it was observed that liver fat was decreased as the cholesterol content increased.

The aboveground production, nutrient distribution and nutrient cyclings were compared between two Phragmites communis communities growing in the different salt contents of soil in a coastal salt marsh. Inorganic nutrient contents of soil for plant growth were greater at the low salt stand than at the high salt stand except for sodium(Na). Maximum aboveground biomass of the plant at the low and the high salt stands were 2,533 and 1,719 g dw/$m^2$, respectively, in August. Seasonal changes of nutrient content of biomass in dry weight decreased with growth except for Na. Nutrient contents in biomass per unit land area increased continuously as biomass increases, although the amount of potassium(K) reached the maximum content in July and thereafter decreased. Vertical distributions of total nitrogen(T-N) and phosphorus(P) increased with plant height, but Na showed the reverse trend. That of K was similar to the patterns for T-N and P in the leaves, and to the pattern of Na in the stems. The Na was greatly accumulated in underground biomass but transported scarcely to aboveground. At the low and the high salt stands, the ratios of the inorganic nutrients contained in the plant were 100 : 66 for T-N, 100 : 61 for P, 100 : 62 for K and 100 : 97 for Na. the ratios of the amounts of nutrients retrieved to soil were 100 : 242 for T-N, 100 : 408 for P, 100 : 127 for K and 100 : 269 for Na, respectively. Turnover times of the T-N, P, K and Na in the communities were 56, 1, 15 and 174 years at the low salt stand, and 75, 2, 24 and 323 years at the high salt stand, respectively. In nutrient cyclings, all of the nutrients retrieving to soil were less than uptake by plant. Among the nutrient, especially P is expected to be exhausted from soil, sooner or later, because of the harvest by men.

The purpose of this study was to investigate consumer preferred formats of nutrition labels: the type of nutritional information provided on the labels. A survey was conducted on 222 housewives between the age of 20 and 65 in Daejeon city in 1998, using an interview questionnaire showing illustrated nutritional label formats. Among twelve nutrients and caloric values listed on the nutrition labels, the housewives ranked their interest in the items in the following order of calorie (58.56%), calcium (56.76%), cholesterol (54.05%), protein (39.19%) and vitamin C (36.04%). The majority of the subjects (69.37%) checked labels when they bought milk or dairy products, whereas only 8.11% looked at labels when they bought Ramyon or noodles. Most of the subjects (90.99%) preferred products with labels with nutritional information as compared with products without labels. this was especially so true of the younger individuals and of pc-ople who checked food labels more frequently. The subjects preferred labeling which described the nutrient content per Package (55.41%), sewing size (32.88%) and food weight of 1009 (11.71%) as a standard nit. Generally, they prefer-red a simplified list to a detailed list of the number of nutrients, a figure graph to bar graph in nutrition claim, vertical bar graph to horizontal bar graph showing the nutritional content of foods and a web-type graphic format to a radiation-format when describing the item's percentage of the Korean RDA's nutrient content. The subjects who checked labels frequently especially preferred detailed list, while housewives with job or with unhealthy family members preferred a simplified list and graphic, rather than a numerical display. From this result, it is suggested that providing consumers with more nutrients information in a more easily understood graphic format would encourage the consumers to check nutritional labels. Therefore this should be considered when developing the regulations far nutrition labeling or when educating the Public about nutrition. (Korean J Community Nutrition 8(2) : 220∼230, 2003)

The effect of milling on the nutrients of raw and parboiled rice grain samples was investigated. Parboiling treatments of choo chung paddy decreased head rice yields and pressure parboiling proved to be more beneficial in reducing white belly rice. Except PP sample mean length/width ratio of parboiled milled rice kernels(8% milling degree) were more larger than raw milled rice and the extent depended on severity of parboil heat treatment. Parboiling had no effect on the protein content of browm rice(0% milling degree) but increased in 4%, 8% milling degree and in PL40 sample. Parboiled rice had a lower fat and the extent depended on degree of milling. Ash content of parboiled brown rice decreasd compared to raw brown rice and generally decreased according to milling degrees were high. Nevertheless, PP, PT40 and PL40 parboiled milled rice samples(0% milling degree) contained more ash than raw milled rice. Parboiling increased total sugar and reducing sugar and increased according to milling degrees were high. Parboiled rice had a high reducing sugar content than raw rice except for PT sample, and more contained as higher milling degree. Total amino acid content of parboiled brown rice increased compared to raw brown rice except for PL40 sample. Parboiled rice of 4% milling degree had a lower total amino acid content and then 8% milling degree had a higher than raw rice. Ca content of parboiled rice was lower than raw rice and tended to have lower as milling degree were high. Parboiled rice of 0 and 4% milling degree had a lower Fe content degree but higher in 8% milling degree. PP and PT40 samples contained more Fe than any other parboiled rice. Parboiled milled rice contained more thiamin than raw milled rice. Rice of milling degree 6% and PL sample contained most thiamin.
