Judging from the studies carried out by Dr. Jo, Yong Jin on the Koreans' faces, Koreans divided into two constitutions according to their facial features and heritages. The one population is the Northern lineage whose ancestor migrated from Siberia in ice age. In order to survive in cold climate, they have developed a high level of metabolic heat production. Cold adaptation for preventing heat loss results in a reduction in the facial surface area with small eyes, nose and lips. The other population is the Southern lineage who is the descent of native in Korean peninsular. They have big eyes with double edged eyelids, broad nose and thick lips. It is generally believed that both genetic and environmetal factors influence eating behaviors. Although we can't recognized their heritage that may contribute to the metabolism and eating behavior, we commonly recognize their physiological heritage acceding to their facial features. In order to investigate the relationship among the size and shape of facial feature, the eating behavior, anthropometric measurement in female college students, the eating behaviors was measured during an instant-noodle lunch eaten in a laboratory setting at the ambient temperature of $23^{\circ}C$. The anterior surface area of left eye and length of right eye were positively correlated with the difference between the peak postprandial and the meal-start core temperature. The surface area of lower lip also negatively correlated with the meal-start core temperature and meal duration. In addition, the total lips' area was positively correlated with the difference between the peak postprandial and the meal-start core temperature and negatively correlated with the meal duration. However anthropometric measurements were not related with the size of facial features.

This study was undertaken to examine the levels of serum lipids and lipoproteins of college students and the correlations between serum lipid levels and food habits. 202 college students(99 males and 103 females) were selected as subjects for this study during November, 1993. The mean height and weight were 173.2 cm, 63.7 kg for males and 159.4 cm, 50.8 kg for females, respectively. The mean serum TC, LDL-C, HDL-C, TG levels were 172.2, 103.4, 52.3 and 82.3 for males and 182.4, 111.6, 56.3 and 72.5 mg 161 for females, respectively. Serum lipid levels of males were significantly lower than those of females except TG. There was no significant difference In TG levels between males and females. Food habit scores of females were significantly higher than those of males. The significantly different items between males and females were numbers of daily meal intake, duration of meal intake, regular daily Intakes of cereals, fruits, vegetables and animal fat, exercise, alcohol intake and smoking. Food habit score of Items except exercise in females were higher than those of items in males. LDL-C and LPH were positively correlated with food habit score. TC and LDL-C were positively correlated with eating-out, alcohol intake, smoking but negatively correlated with numbers of daily meal intake. HDL-C was positively correlated with overeating, but negatively correlated with cholesterol intake. There was no significant correlation between TG and food habit items. Regular meal intake was positively correlated to LPH by having a negative correlation with HDL-C in males and regular daily intake of cereal was positively correlated to LPH by haying a positive correlation with LDL-C in females. There were significant correlation between food habits and anthropometric measurements. Height and weight were positively correlated with daily meal intake and exercise but negatively correlated with duration of meal intake, daily intakes of cereals, vegetables fruits and animal fat, smoking, alcohol intake. Smoking was negatively correlated with height and weight in males, over-eating was negatively correlated with height in females. Finally this study showed an interesting results that balanced intake of five basic food groups were positively correlated with weight in males but with height in females.

The purpose of this study was to investigate effect of living condition and aging on food intake in Korea. 98 free-meal receivers and 81 members in well-being center for the aged were asked about their food frequency and food consumption and their socioeconomic status by a questionnaire. All data were analyzed by SPSS (Statistical Packages for the Social Sciences) 10.0 program. There were statistical differences of living condition, marital status, former job and teeth status between free-meal receivers and people with stable lives. Moreover, all age groups of free-meal receivers had lower income, living expenses, educational period and frequency of physical activity than those of people with stable lives. But smoking and drinking was much higher in free-meal receivers. Arthritis was the most prevalent disease in both groups. And free-meal receivers had higher blood pressure and lower Body Mass Index than people with stable lives. Food consumption of free-meal receivers was definitely lower than that of people with stable lives in terms of food frequency and standard amount of food eaten. But noodles, bean sprouts and eggs were very important foods for free-meal receives. Food consumption of the aged was affected by age, educational period, income, blood pressure, duration after retirement, frequency of physical activity and Body Mass Index. Therefore, as various socioeconomic status affects on food intakes of the aged, more effective and practical nutritional programs which consider the receivers'socioeconomic status are needed for the nutritionally at-risk groups like the aging free-meal receivers.

The purpose of this study was to analyze meal management behaviors for Korea dietary acculturation among multicultural families in Korea. The study compared differences in meal management behaviors among 90 multicultural families. Results of the study were as follows: cultural adaptation to Korea got higher with increasing age; marriage immigrants with longer marriage duration and with children showed higher cultural adaptation to Korea. Regarding food value of marriage immigrant women, 'eating favorite food' was the highest in the 20s, while 'satisfaction with Korean dietary lifestyle' was high in Chinese and in those with longer residency. Most of them replied 'myself' for the meal manager of their multicultural family. When surveyed on major difficulties in Korean meal management, existence of children showed significant difference for 'cooking', and period of residency and existence of children made significant difference for 'taste'. In conclusion, meal management behavior of multicultural families was influenced by socioeconomic factors. Further research is needed for more quantitative analysis and understanding of the effect of dietary patterns on nutritional status and quality of life in multicultural families.

The influence of treated, extruded, partially expelled soybean meals as undegradable protein and bypass fat sources on lactation performance and ruminal fermentation of dairy cows was studied. Experiment 1: nine cows were used in a replicated 3${\times}$3 Latin square design with each period being 3 wk in duration. Cows were fed 440 g/kg forage and 560 g/kg grain diet with one of three extruded soybean meals fed at 110 g/kg of the diet. The 3 soybean meals were 1) twice-extruded soybean meal (ESM; as a control); 2) lignosulfonate-treated, twice-extruded soybean meal (LSM); and 3) calcium oxide plus lignosulfonate-treated, twice extruded soybean meal (CLSM). Experiment 2: 3 ruminally cannulated cows were used in a 3${\times}$3 Latin square to study the treatment influence on ruminal fermentation characteristics. Feeding treated soybean meal to cows in LSM and CLSM treatments did not improve feed intake, milk yield, or milk composition except that cows fed the LSM and CLSM treatments produced less milk protein compared with the ESM treatment. The proportion of $C_{18:2}$ was greater in milk fat of cows fed CLSM compared with that of cows fed the ESM or LSM treatments. Ruminal pH, ammonia, and total volatile fatty acids were not affected by treatment. An increased proportion of $C_{18:2}$ in milk fat suggests that there is a potential use of calcium salts of fatty acids in protecting the lipid portion of extruded soybean meal and further research is needed to explore this potential with full-fat extruded soybeans not with extruded and partially oil expelled soybeans.

Objective: The present study was carried out to evaluate the effect of high dietary cation and anion difference (DCAD) rations on diurnal variations in eating and meal patterns, water intake and urination patterns in dairy goats fed under high ambient temperature (HTa). Methods: Ten crossbred dairy goats during peri-parturition period were selected and divided into two groups of five animals each. Experimental diets were control DCAD (control, 22.8 mEq/100 g dry matter [DM]) and high DCAD (DCAD, 39.1 mEq/100 g DM). The composition of two diets consisted of 44% corn silage and 56% concentrate. From the 2nd week to 8th week postpartum, goats were fed ad libitum twice daily either with the control or DCAD total mix ration with free access to water. The spontaneous eating and drinking patterns were determined. Results: The environmental conditions in the present experiment indicated that goats were fed under HTa conditions (average peak THI = 85.2) and were in heat stress. In addition to the typical HTa induced tachypnoea in both groups, the respiratory rate in the DCAD group was significantly higher than the control group (p<0.05). Although the goats from both groups showed comparable level of eating, drinking and urination during experiment, the meal pattern and water intake were different. High DCAD apparently increased eating and meal patterns compared with the control. At week 8 postpartum, goats from high DCAD group had significant (p<0.05) bigger meal size and longer meal duration. Moreover, high DCAD appeared to increase night-time water intake (p<0.05). Conclusion: Both meal pattern and night-time drinking effects of DCAD suggested that feeding with high DCAD ration may alleviate the effect of heat stress in dairy goat fed under HTa conditions.

In this paper, we propose a method for recognizing eating behavior with almost no motion acceleration. First, by using the acceleration of gravity acting on the wrist direction, we calculate the angle between the gravity and the wrist direction. After that, detect wrist reciprocating motion when peak and vally exist in specific angle band. And then, when accumulate the number of wrist reciprocating motion occurrences are up to 10, then regard as the meal time 5 minutes before the detection time. Also, estimate the meal time only if its duration is more than 7 minutes. Using the data of 2128 minutes, which was collected from four graduate student, the result of the meal time estimation shows 95.63% accuracy.

Eighteen growing male Murrah buffalo (Bubalus bubalis) calves were divided into three groups consisting of six animals each and fed three urea ammoniated wheat straw (UAS) -based rations supplemented with concentrate mixtures (roughage: concentrate ratio 58:42) containing deoiled ground nut cake, GNC (8%), formaldehyde treated GNC (8%) or fish meal (8%) to undertake comparative evaluation of these rations in terms of their $CH_4$ production and growth (285 d duration) potential. A digestibility trial (10 d duration) was followed by a comparative calorimetric study in respiration chamber. Dry matter (DM) intake (84.3 to $89.3g/kg\;W^{0.75}d^{-1}$) did not differ between treatments. The digestibility coefficient of DM, organic matter (OM), crude protein (CP), neutral and acid detergent fiber did not differ significantly in different diets. Urinary energy loss as a percent of gross energy (GE) was not affected by diets. Average values of $CH_4$ production were 84.3, 77.6 and 99.1 g/d and $CH_4$ energy losses as percent of gross energy were 5.7, 5.2 and 6.1 percent on .GNC, formaldehyde treated GNC and fishmeal, respectively, and did not differ significantly. When expressed per unit of digestible OM intake, $CH_4$ production (g) was lower (p<0.05) on formaldehyde treated GNC (30.6) than on untreated GNC (30.6) and fish meal (31.9). Total ME intake and heat production were similar and hence the energy balances on different diets were similar. Nutritive value of rations in terms of digestible CP and ME were similar. Average daily gain calculated on the basis of regression of fortnights on cumulative liveweight gain in calves fed on concentrate containing unprotected GNC, protected GNC and fish meal were 437.1, 483.9 and 481.6 g, respectively. This indicated that the intake of energy was sufficient to meet the requirement of calves growing at 400 g per d. However, CP intake was around 150% of the stipulated standard (Kearl, 1982). Feed conversion ratios on unprotected GNC, protected GNC and fish meal were 11.60, 11.10 and 10.4 respectively. It was concluded that because significantly (p<0.05) low $CH_4$ is produced on protected GNC (8%), it is very good and sustainable protein source in comparison to poor quality fish meal and untreated GNC to be used in concentrate mixture for supplementing UAS-based diets.

One growth trial and one digestibility trial were conducted to evaluate the nutritional value of HP300, a commercially processed soybean meal product for weanling pigs. Dried whey, fish meal and/or full fat extruded soybeans (FFES) as well as portions of soybean meal (SBM) were replaced with HP300 in weanling pig diets. The objectives were to investigate the effects of HP300 on growth performance, digestibility, ileal amino acid digestibility and blood amino acid concentration in weanling pigs. One hundred and twenty crossbred $(Duroc{\times}Beijing\;Black{\times}Landrace)$ pigs weaned at 28 days of age were used in the growth trial. The pigs were randomly allocated to five treatments, with three pens per treatment and eight pigs per pen. The trial duration was 28 days. The control (CTRL) diet contained no HP300; in treatments 2, 3 and 4, dried whey and fish meal were replaced by 3.0%, 7.5% and 10.5% HP300; in treatment 5, full fat extruded soybeans were replaced by 10.5% HP300 plus soybean oil to attain the same metabolic energy content as FFES. Five T-cannulated barrows were used in a digestibility trial with a $5{\times}5$ Latin square design to determine nitrogen retention and amino acid ileal digestibility of HP300 used alone or mixed with other ingredients. The results indicated that replacement of dried whey, fish meal, full fat extruded soybeans and a part of the soybean meal with HP300 in piglet diets improved average daily gain and feed conversion ratio (p < 0.05). There was a trend toward improved DM, crude protein and amino acid ileal digestibilities and improved protein and amino acid ileal digestibilities and improved protein net availability with the use of HP300 in swine diets.
