  • The purpose of this study was to examine the dietary habits and nutrient intakes of school-aged children participating in extracurricular classes, to with regards to class schedule. Three-hundred and two students from Seoul were selected and classified into two groups. One group attended extracurricular classes less than 12.43 hours per week, which was determined as the average number of hours per week(AELT, n=147). The other group attended extracurricular classes more than 12.43 hours per week(AEMT, n=155). The average student age in both the AELT and AEMT groups was 11.9 years, respectively. In terms of height and weight, there were no significant differences between the two groups. AELT received significantly more hours of sleep than AEMT(p<0.01), and there were significantly more responses with regard to lack of sleep in the AEMT group than in the AELT group(p<0.05). In a survey on 17 clinical symptoms regarding health, the AEMT group had significantly higher response rates than the AELT group in the following sections: no appetite (p<0.001), dizziness(p<0.001), headache(p<0.01), tiredness(p<0.01), cold symptoms(p<0.05), and sore eyes(p<0.05). Meal time irregularity was significantly higher than AEMT than in AELT(p<0.05). Approximately 50% of the subjects were picky eaters, and 40% and 20% skipped breakfast or dinner, respectively. The average energy intakes for AELT and AEMT were 2122.2 kcal and 2061.5 kcal, respectively, and there was no significant difference between the two groups. AEMT consumed significantly lower quantities of protein, animal fat, vitamin $B_6$, calcium, and phosphorus(each p<0.05) as compared to the AELT group. Beverage intake was significantly higher in AEMT than AELT(p<0.05). The number of hours in extracurricular classes showed a significant negative correlation with the intakes of protein, animal protein, animal fat, vitamin $B_6$, folate, calcium, plant calcium and phosphorus(each p<0.05). The number of hours in extracurricular classes also showed a significant negative correlation with soy foods intake(p<0.05). These results suggest that continuous and systematic nutritional education should be performed in order to prevent and improve the unbalanced diets and problematic of dietary habits that may result in students due to attendance in extracurricular classes.

  • This study was performed to investigate the information of food preference of workers for meal served by industry foodservice. The subjects were composed of 212 office workers and 220 laborers. The results were obtained as follows : 50.7% of the subjects were 30∼39 years old ; 72.0% of them had high school education ; the type of favored food was Korean style cooked rice ; food taste was the most important point in food selection. Preference form main foods : Cooked rice was preferred the most by the subjects. Both office workers and laborers liked Kalkooksoo and vegetable bread and cooked rice covered with beef was preferred by office workers and cooked rice covered with raw fish pieces was preferred by laborers. Also they disliked Hash rice, Curry rice and rice-cake soup in the pattern. Preference for side-dish : The Acceptances for side-dishes were high in soybean paste soup(office workers : 37.5%, laborers : 31.5%), hot chowder of corvina(26.1%, 25.7%), kimchi stew(30.5%, 28.8%), beef broiled in soy(32.5%, 30.5%), baked fish(32.5%, 31.9%), pachon(20.7%, 25.9%), a meat inside a razor clam(25.1$, 29.2%) and Chinese cabbage kimchi(44.5%, 46.3%), in that order by both of them. But in office workers, seasoned bean sprouts and steamed beef-rib were shown to have high preference and in laborers seasoned spinach and steamed pork-rib were high. Preference of snacks : The preferences for snacks were high in milk(office workers : 50.3%, laborers : 48.5%), Songpean(28.9%, 30.1%), coffee(30.8%, 32.5%), Sikhye(18.8%, 17.5%), in that order by two groups.

  • The purpose of this study was to investigate the effect of freezing and thawing rate on the physical properties of soybean sprouts to improve the quality of processed soybean sprouts during distribution and storage. Cooked soybean sprouts were frozen by air-blast freezing (ABF) system at $-45^{\circ}C$ or natural air convection freezing (NCF) system at $-24^{\circ}C$, then thawed using microwave oven by varying output power (0, 400, 800 and 1,000 W) until $75^{\circ}C$. The quality of soybean sprouts was measured by the water content, hardness and springiness. In addition, the internal microstructure of soybean sprouts was observed by optical microscope. For results, water content of soybean sprouts thawed by 1,000 W in a microwave showed the lowest value after natural air convection freezing. Springiness of soybean sprouts thawed by all amounts of output power was decreased in comparison with control. Hardness was increased only in soybean sprouts thawed by 1,000 W after air-blast freezing. However the gaps between springiness and hardness were relatively small with control at 1,000 W thawing, after air-blast freezing. Internal microstructure of the soybean sprouts was more damaged as freezing and thawing time were increased. In conclusion, high freezing and thawing rate might improves the quality of soy bean sprout, and IQF freezing and 1,000 W of microwave thawing appears to be the optimum condition for frozen HMR production. From the results freezing and thawing process parameters might can be use as quality control parameters as various type of sprout products processing.

  • Effect of extraction pH on mechanical properties such as tensile strength (TS) and elongation (E) and on water vapor permeability (WVP) of soybean protein isolate (SPI) edible films extracted from soybean meal was investigated. Five pHs, acidic range (pH 2.0 and pH 3.0), neutral range (pH 7.0) and alkalic range (pH 10.0 and 12.0), were used to extract SPI. TS of the film extracted at pH 7.0 was the lowest, and WVP of $SPI_3$ (SPI extracted at pH 3) film was the lowest value among the films. The WVP of $SPI_3$ films was $3.349\;{\times}\;10^{-10}\;g{\cdot}m/m^2{\cdot}s{\cdot}Pa$ and increased to $3.871\;{\times}\;10^{-10}\;g{\cdot}m/m^2{\cdot}s{\cdot}Pa$ as film thickness increased from $55\;{\mu}m$ to $72\;{\mu}m$ thickness. Three different plasticizers (glycerol, polyethylene glycol and propylene glycol) were used for $SPI_2$ (SPI extracted at pH 2) film. TS of $SPI_2$ films was 12.297 MPa and decreased to 1.356 MPa for glycerol and showed the same trend in other two plasticizers. The SPI films extracted at acidic range were shown higher mechanical properties and lower water vapor permeabilities than those of extracted at neutral and alkalic ranges. The difference of SPI film properties seemed to be attributed by 11S/7S ratio as well as protein content.

  • Ammonia gas is one of the major pollutants which cause environmental pollution and damage to the human and the livestock. The objective of this study was to investigate the important parameters for the development of efficient removal of ammonia gas by Bacillius subtilis IB101 and to optimize the medium composition for the mass production of B. subtilis IB101. The ammonia gas removal efficiency was evaluated at different growth phases and by changing culture conditions (temperature, pH). The effect of $(NH_4)_2SO_4$ concentration in preculture medium was examined. Medium optimization for the mass production of B. subtilis IB101 was performed by using Plackett-Burman design and one factor at a time method. The removal of ammonia gas was more efficient at exponential phase by 20% than at stationary phase. The ammonia gas removal was the highest at pH 4 and 30 $^{\circ}C$. There was not any significant influence of concentration of $(NH_4)_2SO_4$ on the removal of ammonia gas. The components of optimized medium for the production of viable Bacillus subtilis IB101 was yeast extract 10 g/l, soluble starch 2.5 g/l, $MgSO_4$ 6 g/l, $CaCl_2$ 1.55 g/l, $(NH_4)_2SO_4$ 5 g/l, $KH_2PO_4$ 0.75 g/l, soy bean meal 8 g/l.

  • A study was conducted to investigate the effect of dietary supplementation of feedstuff of Chlorella (Chlorella vulgaris) to replace of antibiotic in the diets of broiler chickens. A total of 720 1-d-old straight run broiler chicks (Ross ${\times}$ Ross) was randomly assigned into six treatments with four replicate pens (30 birds/replicate pen) for 5-wk. A corn-soy bean meal basal diet was formulated, the treatment groups were negative group (NC, antibiotic-free diet) and 0.1% virginiamycin in as antibiotic growth promoters (PC), 1.0% fresh liquid Chlorella (T1), 1.0% dried Chlorella powder (T2), 1.0% commercial Chlorella product and 1.0% (T3) and commercial Chlorella product 0.5% (T4) were added to the basal diet to form six dietary treatments. No significant differences were found among the treatments for feed intake and feed conversion of broiler chickens during the whole experimental period, but the BW gain was significantly higher (P<0.05) in commercial Chlorella product supplemental groups than the control group (NC and PC groups). Dietary supplementation of Chlorella significantly (P<0.05) increased the plasma IgA, IgM and IgG concentration of chicks compared to NC and PC groups. Supplemental AGPs and commercial chlorella product did not affect the E. coli and Salmonella concentration in the intestinal microflora of broiler chicks; however, the population of Lactobacillus was significantly increased (P<0.05) when birds were fed commercial Chlorella product groups. It is concluded that commercial Chlorella product supplementation could be used as an alternative of antibiotics to promote growth and immune response by increasing the production of lactic acid bacteria in the intestinal microflora of broiler chickens.

  • The present study was performed to analyze the life style and eating behavior of stroke patients and to find the risk factors related to stroke incidence in Daegu and Gyeongbuk Province, Korea. The case subjects (n=100) were selected from newly diagnosed stroke patients at Kyungpook National University Hospital. The control subjects (n=150) were selected from community inhabitants who did not have stroke history and were sex and age-matched with the case subjects. The survey was conducted by individual interviews using questionnaires on the general characteristics, life-style, eating behavior, food intake frequency and food preference. The high body mass index, preexisting diseases such as diabetes and hypertension, stroke family history, smoking, overeating habit and high preference for sweet, greasy and meat foods appeared to be the risk factors for stroke incidence. On the other hand, the results suggest that life style of regular exercise and nonsmoking, food habits of green tea drinking and enough chewing, preference for Korean meal type, high intake frequency for legumes, vegetables, mushrooms, seaweeds, fishes and shell fishes, soy milk and green tea might be the protective factors for the stroke. Therefore, maintenance of healthy weight, the prevention and management of the deteriorative chronic diseases, change of life style and improvement of eating behaviors are considered to be important for stroke prevention.

  • There are approximately 1,500 broiler farms in Korea, each raising 55,000 birds. Ninety-five percent of the farms are contracted with Integration Company. According to the Korean broiler performance index, broilers in Korea are marketed at 32 days with 1.52 kg of body weight. In contrast, the market age and body weight of broilers are 47 days/2.8 kg in the United States and 42 days/2.5 kg in Europe. Because of the younger market age of the Korean broiler, the pre-starter feed is important. Chicks exhibit poor absorption of dietary nutrients up to 7 days after hatching due to an immature digestive system and low enzyme secretion rate and activity. At the beginning of hatching, chicks obtain their nutrients from the egg yolk sac. It is highly recommended that chicks, after consuming the nutrients in the egg yolk sac, are given supplemented pre-starter feed to increase early growth rates and improve the performance of broiler production. Pre-starter nutrient requirements are not expressed in NRC, so Korean feeding standards for poultry and commercial breeding companies determine the nutrient requirements of pre-starter broiler chickens. Three approaches are followed to formulate specially designed pre-starter feeds for broiler chicks: (i) selective use of raw materials, (ii) proper standards of nutrient supply, and (iii) application of feed additives such as exogenous enzymes. In the selection of raw materials, those with high digestibility can be used. The absorption rate of carbohydrates in grains can be increased through feed processing at high temperature and high pressure. Soy proteins and fish meal can also be added as protein sources. As an energy source, vegetable oils are preferred over animal fats because of the former's high digestibility. It is suggested that the levels of proteins and amino acids are higher in pre-starter feed than in starter feed. With regard to energy, the sources of energy are more important than the levels of energy in feed. Feed additives such as exogenous enzymes can be used to improve nutrient digestibility. In addition, organic acids and plant extracts can be used as alternatives to animal growth promoters to stimulate immunity and prevent diseases. The growth performance of broilers is affected by various factors, such as management and disease control, in addition to the nutritional strategy; however, nutritional strategies play an important role in improving the productivity of broilers. Therefore, nutritional strategies, along with management and disease control, are required for improving the productivity of broilers in Korea.

  • The dietary habit, health condition and the cognition concerning the health food have been surveyed with the help of the 151 old people living in In-Cheon and Seoul. In this study, the old are classified as an institution for the aged and the old in their own home. The preference and mental health condition influenced on dietary habits have been surveyed as wall. Their dietary habits such s three meals a day and a regular meal time have show) that they have generally good eating habits. Psychologically, the old in an institution for the aged think their health condition is not so good in comparison with the old in their own home. The old in their own home have good condition in that they can go up the stairs, exercise often and walk relatively well. Moreover, men's health condition is better than women. The old generally like meats(especially beef) and prefer sesame oil, perilla oil, soy been oil to Western oil. They like sweat flavor the most and hot, salty taste in order. Thier favorite cooking method is a pot stew, soup and season. The difference between dietary habit and mental health based on an academic career, an allowance and a residential condition shows that the old who live alon have relatively terrible eating habit and the more learned, the better. The more pocket money they have, the better dietary habits they have. The old feel glommy in general and the old in an institution are more depressed and it is statistically significant.
