For the past 10 years, the socioeconomic status of our country was markedly improved. Accordingly, our foodintake patterns and other alt parts are preparing to blance with developed countries. Especially, be westernizing or improving our foodintake patterns, we intake much fat diet(animal food) while our physical activities decrease and alcohol consumtion's population, smoking population gradually increase. For such reasons, the population of obese tendency and cardiovascular diseases are increased. According to recent reports, among all death causes in our country, cardiovascular diseases(hypertension, hypertensive cardiovascular diseases, ischemic heart diseases) occupyd top rank, we know. I(the author) studied the inter-relation between serum cholesterol level which is the important factor of the cardiovascular diseases and essential hypertension liver diseases, hyperglycemia, some cardiac problems which are main decline causes in life insurance's medical assessment, and body weight distribution. Studied samples were selected on 4,313 cases(male; 1,791, female; 2,522) who were tested liver function test from June, 11th, 1980 to Dec., 31st, 1983 on our medical department's laboratory. I selected two groups in those cases: one group was serum cholesterol level 180mg/dl over(11% of whole LFT examed cases: No=502 cases), the other group was serum cholesterol level 120-160mg/dl(No= 502 cases). For convenience, the group of serum cholesterol level 180mg/dl over was "A" the other group was "B", I described. All examed persons of LFT were resident m Tae-Jon city in that time. On the result, 1) Decline rate is 10.5% on the "A" group, 5.9% on the "B" group. "A" group reveals 1.8 times higher than "B" group. 2) On decline causes, Essential hypertension is 4.0 times higher on the "A" group than "B", liver function's abnormalities are 2.0 times higher on "A" group than "B" and other diseases are same on "A" and "B". On the "A" group, essential hypertension is considerably higher than "B" group. 3) On the body weight distribution, the cases of 70kg(B.W.) over is 19.7% on "A", 10.6% on "B" group. Obese tendency is 1.8 folds higher on "A" group than "B" group. Studing the result, we find high serum cholesterol concentration is closely related with essential hypertension, obese tendency and liver function's abnormalities on the life insurance's medical examination part, also. On the future, we will more carefully consider the serum cholesterol concentration on our medical examnination and assessment of life insurance, I think.

This study evaluated the effect of Candida norvegensis (C. norvegensis) viable yeast culture on in vitro ruminal fermentation of oat straw. Ruminal fluid was mixed with buffer solution (1:2) and anaerobically incubated with or without yeast at $39^{\circ}C$ for 0, 4, 8, 16, and 24 h. A fully randomized design was used. There was a decrease in lactic acid (quadratic, p = 0.01), pH, (quadratic, p = 0.02), and yeasts counts (linear, p<0.01) across fermentation times. However, in vitro dry matter disappearance (IVDMD) and ammonia-N increased across fermentation times (quadratic; p<0.01 and p<0.02, respectively). Addition of yeast cells caused a decrease in pH values compared over all fermentation times (p<0.01), and lactic acid decreased at 12 h (p = 0.05). Meanwhile, yeast counts increased (p = 0.01) at 12 h. C. norvegensis increased ammonia-N at 4, 8, 12, and 24 h (p<0.01), and IVDMD of oat straw increased at 8, 12, and 24 h (p<0.01) of fermentation. Yeast cells increased acetate (p<0.01), propionate (p<0.03), and butyrate (p<0.03) at 8 h, while valeriate and isovaleriate increased at 8, 12, and 24 h (p<0.01). The yeast did not affect cellulolytic bacteria (p = 0.05), but cellulolytic fungi increased at 4 and 8 h (p<0.01), whereas production of methane decreased (p<0.01) at 8 h. It is concluded that addition of C. norvegensis to in vitro oat straw fermentation increased ruminal fermentation parameters as well as microbial growth with reduction of methane production. Additionally, yeast inoculum also improved IVDMD.

This study was conducted to evaluate the effect of dietary supplementation with rice bran, flax seed, or sunflower seed to finishing native Korean cattle (Hanwoo) on growth performances, carcass characteristics, fatty acid composition, free amino acid and peptide contents, and sensory evaluations of Longissimus muscle (LM). A total of 39 Hanwoo steers (average age of 22.2 mo and average body weight (BW) of 552.2 kg) were randomly divided into Control, rice bran (RB), flax seed (FS), or Sunflower seed (SS) groups. The steers were group fed for 273 d until they reached an average age of 31.2 mo. Final BW was 768.2, 785.8, 786.2, and 789.0 kg, and average daily gain was 0.79, 0.85, 0.82, and 0.84 kg for the Control, RS, FS, and SS groups, respectively (p>0.05). Fat thickness of the FS group (19.8 mm) was greater (p<0.05) than that of the other groups. Final yield grade converted into numerical values was 2.0 for the RB group, 1.7 for the Control and SS groups, and 1.4 for the FS group. Marbling degrees for the Control, SS, RB, and FS groups were 5.3, 5.1, 4.7, and 4.6, respectively. Percentages of palmitic acid ($C_{16:0}$), stearic acid ($C_{18:0}$), and arachidic acid ($C_{20:0}$) in the LM were not different among the groups. Palmitoleic ($C_{16:1}$) acid was higher (p<0.05) in the SS group. The concentration of oleic acid was highest (p<0.05) in the Control group (47.73%). The level of linolenic acid ($C_{18:3}$) was 2.3 times higher (p<0.05) in the FS group compared to the other groups. Methionine concentration was (p<0.05) higher in FS (1.7 mg/100 g) and SS (1.2 mg/100 g) steers than in the Control or RB groups. Glutamic acid and ${\alpha}$-aminoadipic acid (${\alpha}$-AAA) contents were (p<0.05) higher in the FS group compared to the other groups. LM from the FS group had numerically higher (p>0.05) scores for flavor, umami, and overall palatability in sensory evaluations. In conclusion, supplementation of flax seed to diets of finishing Hanwoo steers improved sensory evaluations which might have been caused by increases in flavor related amino acids such as methionine, glutamic acid and ${\alpha}$-AAA and peptides, anserine and carnosine, and their complex reactions.

In order to utilize health food chick bean as a raw material for cosmetics, the skin improvement effect of a mask pack made of chickpea Natto fermented with Bacillus subtilis Natto strain was studied. Powder obtained by lyophilization of chickpea Natto was applied to a facial mask pack as a paste formulation. This Natto pack was applied to subjects in their 50s and 60s to investigate their effect on skin improvement. As the number of treatments of Natto pack increased, the skin was improved and the improvement effect was remarkable after 4 treatments. After four times treatments, moisture content and sebaceous secretion increased by $8.4{\pm}3.6%p$ and $4.0{\pm}2.3%p$, respectively. Skin pores and wrinkles were also decreased by $1.8{\pm}0.3%p$ and $1.8{\pm}0.9%p$, respectively. Skin pigmentation decreased by $1.3{\pm}0.2%p$ and skin tone also increased from 55.2% to 55.9%. These results indicate that Natto product obtained by fermenting chickpea has the effect of improving skin such as moisturizing, pore, wrinkle, pigmentation, sebum secretion and skin tone, and can be used as a raw material for various functional cosmetics.

Purpose - The perception of the quality of the consumer's distributor's brand(PBs) is generally perceived to be lower than that of the manufacturer's brand(NB), although it is a critical factor in determining the success of PBs. Accordingly, this study examines the characteristics of the convenience store PB products and their correlation with brand trust and purchase intent in the consumers who have had experience purchasing the convenience store PBs to expand the sales variables. Further, this research shows that the marketing strategy is to increase the share of PBs by providing an empirical analysis on the effect of the product attribute factors on the sales volume associated with brand trust, purchase intent, and others. Research design, data, and methodology - The survey period of this study was approximately three weeks from December 1, 2017 to December 21, 2017. The study samples that were taken from 100 random people extracted. The statistical analysis was carried out with multiple regression analysis using the SPSS statistical package. Results - The analysis shows that the brand credibility and purchasing intention were statistically significant differences between the private convenience store private brand products. Specifically, brand trust showed a statistically significant relationship the brand images and quality levels, but the perceived value was not affected statistically. Although the intent of the purchase showed a statistically significant relationship the quality level and the perceived value, the brand image was not statistically significant in its relationship. Conclusions - Overall, it has been established that the perception value does not statistically affect brand trust for convenience store PB products, and that the brand image has no statistically significant effect on the purchase intent. These results are analyzed to be due to the influence of brand in convenience stores themselves rather than brand trust and purchase intentions that affect sales performance, which is the property of private brand food and beverage products, the perceived value of their products. Accordingly, the study found that not only did the marketing performance of the convenience store PB products be improved statistically, but also the cause of the product attributes that were not statistically significant was identified.

This study was conducted to evaluate the chemical composition, digestibility, and energy value of 15 non-conventional feeds produced in South Korea as ruminant feeds. Three Hanwoo steers (body weight, $520{\pm}20.20kg$) fitted with a permanent rumen cannula and duodenal cannula were housed individually in tie-stall barns, followed by a 14-day adaptation period and 3-day experimental period. Chemical composition analysis, in situ nylon bag, and mobile bag technique were used as experiments. As a result of the chemical composition analysis offeeds, crude protein (CP) contentsofmalt meal, perilla meal, soy sauce cake, and soymilk residue were greater than 30%. As a result of the degradability characteristics analysis of feeds using an in situ nylon bag, rumen undegraded protein (RUP) contents of beet pulp, brewer's grain, coffee meal, malt meal, milo bran, perilla meal, ramen residue, and soymilk residue were greater than 50%. Analysis of total digestible nutrient (TDN) values of feeds using an in situ mobile bag showed that TDN values of beet pulp, brewer's grain, makgeolli residue, milo bran, perilla meal, ramen residue, rice bran, soy sauce cake, soybean curd cake, soymilk residue, and wheat bran weregreater than 50%. In summary, these non-conventional feeds have high potential value as good feed resources to replace formulated feeds or roughage. Therefore, the chemical composition, digestibility, and energy value of non-conventional feeds obtained from this study can be used as base data for the manufacture of ruminant total mixed ration (TMR) with improved feed efficiency, reduced feed costs, and reduction of environmental pollution.

This study was designed to investigate the effects of iron supplementation and nutrition education on the iron status and anemia of high school girls. The subjects resided in Ulsan city in Korea and were already diagnosed as having anemia or iron deficiency. Over a period of three months, one iron tablet (80 mg Fe as ferrous sulfate/day) was administered to the iron deficient subjects and two tablets (160 mg Fe as ferrous sulfate/day) were administered to the anemia subjects. The average height and weight of anemia subjects were 161.24 $\pm$ 4.50 cm and 50.87 $\pm$ 5.86 kg, respectively. The average BMI (kg/$m^2$ )was 19.58 $\pm$ 2.03 and the PIBW(percent ideal body weight) were 92.52 $\pm$ 9.84%. Except for vitamin A and vitamin C intakes, the intake levels of all other nutrients were below the RDA. Total calorie intakes of anemia subjects were 73.5% of RDA. The iron intakes of subjects from food were 69. 1% of RDA and the Ca intakes were 59.1% of RDA. The basal hemoglobin(Hb) concentration of anemia subjects averaged 10.77 $\pm$ 1.33 g/dl, and this increased significantly (p < 0.001) to 12.12 $\pm$ 1.08 g/dl, after iron supplementation. The basal ferritin, and transferrin saturations ｛TS (%)｝of anemia subjects were 12.51 $\pm$ 15.19 ng/$m\ell$ and 8.43 $\pm$ 7.56%, respectively, and these significantly increased to 20.59 $\pm$ 22.39 ng/$m\ell$ and 15.56 $\pm$ 12.87%, respectively. The level of total iron binding protein (TIBC) significantly decreased from the initial 486.80 $\pm$ 70.16 $\mu\textrm{g}$/dl to 417.86 $\pm$ 67.73 $\mu\textrm{g}$/dl (p < 0.001) after iron supplementation. For the iron deficiency subjects, the ferritin, iron and TS(%) levels were increased significantly (p < 0.001) and the TIBC levels were significantly (p <0.001) decreased after iron supplementation. Anemia symptoms such as 'Feeling blue (p<0.05)', 'Decreased ability to concentrate (p<0.001)' and 'Poor memory (p<0.05)' improved significantly after iron supplementation in the anemia subjects. The number of tablets administered was positively correlated with changes in serum hemoglobin (t=0.194, p< 0.01), serum ferritin (t=0.181, p<0.01), TS(%) (t=0.141, p<0.05), and hematocrit (t=0.254, p<0.01), and was negatively correlated with changes in TIBC (t=-0.143. p<0.05) and red cell distribution width (RDW, t=-0.140, p<0.05). In conclusion, daily iron supplementation was effective in improving the iron status and reducing symptoms of anemia in high school girls. (Korean J Nutrition 35 (9) : 943~951,2002)

Purpose: The aim of this study was to determine the effects of nutritional intervention focused on a Nutrition Support Team (NST) in patients receiving enteral nutrition (EN) in general hospital wards. Methods: The electronic medical records of 95 adult patients admitted in C university hospital and received EN supply for more than 3 days at a general ward were analyzed retrospectively. The subjects were classified into the intervention group (n = 40) and non-intervention group (n = 55). Results: The calorie support rate (%) and protein support rate (%) increased significantly only in the intervention group after 2 weeks compared to the rate upon admission. The serum albumin levels increased in the intervention group after 2 weeks compared to the levels at admission, but decreased in the non-intervention group. The glucose levels decreased only in the intervention group compared to that at admission. Conclusion: The nutritional status of the patients was improved by the proper planning of nutrition management from the beginning of hospitalization and systematically managing the nutrition intervention of the NST.

Purpose - This study investigated the effects of consumers' selection criteria for environment-friendly agricultural products on purchase intention and the effects of consumers' attitudes and the reliability of environment-friendly agricultural products on purchase intention by using the theory of planned behavior. Subjective norms of variables of behavioral intention, attitudes toward behavior and control of the behavior were used to create selection criteria, consumers' attitudes and reliability of environment-friendly agricultural products. The study investigated the effects of consumers' selection criteria, attitudes, and reliability of environment-friendly agricultural products on purchase intention constructing models and hypotheses of mediation and moderation between selection criteria for agricultural products and purchase intention by consumers' attitudes and reliability. Research design, data, and methodology - The findings were as follows: first, consumers' selection criteria for environment-friendly agricultural products had a significantly affirmative influence upon purchase intention. Health was the most important factor of selection criteria convenience was more important than quality and familiarity was next. Consumers' attitudes and trust had a significant influence on purchase intention. Second, testing showed that consumers' attitude and trust partially mediated selection criteria: sub-factors and purchase intention were important in selection criteria. Third, testing showed that consumers' attitude and trust had a significant moderation effect between selection criteria and purchase intention. In the test of the moderation effect between sub-factors of selection criteria and purchase intention, consumers' attitude had a significantly positive influence upon health, convenience, and familiarity, and had no significant influence upon quality and purchase intention. Consumers' trust had no significant influence upon health, convenience, and quality. Results - The study provided several theoretical implications: first, an empirical analysis was undertaken with selection criteria for environmental-friendly agricultural products, consumers' attitude, and trust to investigate subjective norms, attitude toward behavior and control of behavior based on the theory of planned behavior. Second, this study investigated both the mediation effect and moderation effect of consumers' subjective norms on attitudes toward behavior, the mediating effects of perceived behavior control and changes of behavioral intention depending upon size and direction of the variables. This study also provided several practical implications. Conclusions - First, consumption of environment-friendly agricultural products did not increase despite rapid increase of production therefore, promotion of consumption and distribution was needed considering the supply and demand of the products. Second, definite standards for selection criteria were suggested to build up consumers' attitude and trust. Consumers' attitude could be improved by factors including the brand of environment-friendly agricultural products, consistent quality, solving physiological problems caused by adverse effects of environmental problems, supplementary approaches, treatment of adverse effects by eating food, and the development and supply of products in accordance with changes of lifestyle. Finally, consumers' demand for sub-factors of selection criteria could be much higher than health, convenience, and quality of the products. Therefore, a process was needed that could continuously check consumers' needs for the products. Limitations were described at the end of the study.

We propose the HBEM(Hybrid Behavior Evolution Model) composed of rule classification and evolutionary neural network using rule descriptor and link descriptor for evolutionary behavior of virtual robots. In our model, two levels of the knowledge of behaviors were represented. In the upper level, the representation was improved using rule and link descriptors together. And then in the lower level, behavior knowledge was represented in form of bit string and learned adapting their chromosomes by the genetic operators. A virtual robot was composed by the learned chromosome which had the best fitness. The composed virtual robot perceives the surrounding situations and they were classifying the pattern through rules and processing the result in neural network and behaving. To evaluate our proposed model, we developed HBES(Hybrid Behavior Evolution System) and adapted the problem of gathering food of the virtual robots. In the results of testing our system, the learning time was fewer than the evolution neural network of the condition which was same. And then, to evaluate the effect improving the fitness by the rules we respectively measured the fitness adapted or not about the chromosomes where the learning was completed. In the results of evaluating, if the rules were not adapted the fitness was lowered. It showed that our proposed model was better in the learning performance and more regular than the evolutionary neural network in the behavior evolution of the virtual robots.
