  • Objectives: The purpose of this study was to analyse the relationship between eating behaviour and healthy dietary competency of single and multi-person households, to improve healthy eating behavior. Methods: This study was conducted on 6,355 adult household members who participated in the Food Consumption Behavior Survey 2020. The subjects were divided into age groups comprising young people in their 20s and 30s, middle-aged people in their 40s and 50s, and the elderly in their 60s and above. The eating behavior and healthy dietary competency of single-person and multi-person households were then analyzed. Results: The average age of the members in the single-person households was found to be higher. Single-person households were also found to have a lower marriage rate and lower monthly household income than multi-person households across the age groups of young, middle-aged, and elderly people (P < 0.05). Among each of the age groups, single-person households had significantly higher rates of skipping breakfast and eating breakfast, lunch, and dinner alone than multi-person households (P < 0.05). Young single-person households had lower average scores on healthy dietary competency than multi-person households (P = 0.032). When adjusted for age, gender, marriage, education, occupation, and household income, single-person households had a higher risk of delivery/take-out, eating out, or skipping meals compared to multi-person households (P < 0.05). In multi-person households, the risk of skipping meals, eating alone, eating out, or delivery/take-out decreased as healthy dietary competency improved (P < 0.05). On the other hand, in single-person households, as healthy dietary competency increased, the risk of delivery/take-out or eating alone decreased (P < 0.05). Conclusions: The results of this study suggest that healthy dietary competency and eating practices can be improved by providing customized dietary education by age group for single and multi-person households.

  • Understanding muslim consumers' needs and behaviour is an essential process for strategic product development in the Halal food market. For our study on Indonesian consumers of Halal food, we conduct a survey of 200 Muslims residing in Indonesia on awareness of ginseng (G) and red ginseng (RG) products, eating experience, like or dislike reasons, cognitive level on the efficacy of G and RG products, purchase behaviors, satisfaction and repurchase intention through a web-based questionnaire methodology. This study reveals that 58 % and 51% of the participants indicate an awareness of G and RG products. In particular, awareness amongst medium- and high-income male consumers in their 20s and 30s is relatively high. This group of participants is also more likely to consume eat G and RG products for health promotion, refreshment, and disease prevention, and positively evaluated product efficacy. They are also aware of the efficacy claims of these products with regard to enhancement of immunity, fatigue, and stamina. While Indonesian Muslim consumers express satisfaction with the health claims, packaging specifications, and design of the products, they are dissatisfied with product types, price, taste, and aroma. The results also found that participants would recommend G and RG products to acquaintances, and are willing to purchase them in the future. Therefore, the segmentation of Halal-certified G and RG products for Muslim consumers and analysis on their product needs could be advantageous for strategic product development.

  • The objective of this study is to investigate the contamination levels and dispersion patterns of arsenic and heavy metals and to estimate the bioaccessible fraction of the metals in soil and plant samples in the vicinity of the abandoned Songcheon Au-Ag mine. Tailings, soils, plants (Chinese cabbage, red pepper, soybean, radish, sesame leaves, green onion, lettuce, potato leaves, angelica and groundsel) and waters were collected around the mine site. After appropriate preparation, all samples were analyzed for As, Cd, Cu, Pb and Zn by ICP-AES and ICP-MS. Elevated levels of As and heavy metals were found in tailings. Mean concentrations of As in agricultural soils were higher than the permissible level. Especially, maximum level of As in farmland soil was 513 mg/kg. The highest concentrations of As and Zn were found in Chinese cabbage (6.7 mg/kg and 359 mg/kg, respectively). Concentrations of As, Cd, and Zn in most stream waters which are used for drinking water around this mine area were higher than the permissible levels regulated in Korea. Maximum levels of As, Cd and Zn in stream waters were 0.78 mg/L, 0.19 mg/L and 5.4 mg/L, respectively. These results indicate that mine tailings can be the main contamination sources of As and heavy metals in the soil-water system in the mine area. The average of estimated bioaccessible fraction of As in farmland soils were $3.7\%$ (in simulated stomach) and $10.8\%$ (in simulated small intestine). The highest value of bioaccessible fraction of metal in farmland soils was $46.5\%$ for Cd.

  • The purpose of this study was to investigate the relationship of body mass index with environmental and dietary factors including nutrition knowledge, and nutrition attitude of Korean adolescents. Anthropometric measurements, questionnaire responses, and 24-hour dietary records of 531 elementary, 543 middle, and 533 high school students residing in Seoul and Kyunggi-do were collected. Data was analysed using SAS computer program. The results are as follows. Mean BMI of elementary school boys was higher than that of girls. However, there were no significant differences in mean BMI between sexes both in middle and high school students. Calcium and iron consumption were lowest among elementary and middle school students, respectively when the intake was expressed as a percentage of the Korean RDA. Energy, protein, vitamin A, vitamin B$_1$, vitamin B$_2$, niacin, and vitamin C intakes(% RDA) were lowest among high school students. The factors influencing BMI of elementary students were BMI of the parents in boys, and BMI of the father in girls. In middle school students, energy intake, fathers BMI, mothers nutrition knowledge and students BMI, and nutrition knowledge were related to the obesity indices of boys, while fathers and mothers BMI were related to the mean obesity index of girls. In high school students, nutrition knowledge and mothers nutrition attitude were related to the obesity index of boys, while BMI of parents was related to the obesity index of girls. In conclusion, mothers and fathers BMI were the most common factors influencing the BMI of these adolescents. Although these results can not determine if food behaviour directly affects BMI, it may influence the BMIs of family members, and therefore nutrition education to keep normal weight and desiradle food habits should be emphasized. More systematic studies to investigate the cause-effect relations of these factors are required.

  • Since obesity has been a crucial issue regarding children's health in Korea, numerous studies have been conducted. However, it is difficult to locate studies that can help researchers and/or medical professionals who want to study behavioral differences between obese and normal weight (non-obese) children. The collected literature about obese childrens behaviors were accumulated by performing 'key word' searches from several web engines: 'obesity' 'children obesity' 'behavior' 'habit' 'eating behavior or habit' 'exercise' 'physical activity' and 'daily behavior'. The information was extracted and the behaviors were reviewed utilizing 30 papers that revealed any differences from normal weight children with at least p .05 level of significance. According to those studies, the obese children tended to skip meals more often as a method of losing weight. They also have an increased appetite, eat larger portions and rarely leave food on their plates. The obese children prefer to eat high fat, high calorie foods and eat faster than their normal weight counterparts. Also, the children usually eat alone and eat at irregular meal times. Beside the behaviors related to the standard three meals a day, obese children have high preferences for snacking. The children reported that with pocket money they usually eat certain types of snacks without parent approval. The children stated that they exercise more on a regular basis. However, when asked about their participation they were not likely to engage actively. Meanwhile, they tend to spend free time doing sedentary activities such as watching TV or playing on the computer. Since these studies used self -reported questionnaires with a small sample, size there may be difficulty in forming a basis about obese children's behaviors. Nevertheless, these findings are in accordance with other studies conducted in local as well as western countries. In conclusion, obese children have different daily behaviors or routines from normal weight children. It is recommended that altering these behavioral patterns to match those of normal weight children should be encouraged.

  • DA-125, a new anthracycline antitumor antibiotic, was administered at dose levels of 0, 0.04, 0.2 and 1.0 mg/kg/day intravenously to pregnant and subsequently delivered Sprague-Dawley rats from day 17 of gestation to day 21 of lactation. Effects of test agent on general toxicity of dams and growth, behaviour and mating performance of F1 offspring were examined. At 1 mg/kg, one out of the twentytwo dams showed difficult delivery, characterized by a stillbirth. Reduction in body weight, loss in food intake, and decrease in spleen weight were also observed in dams. In addition, the lower rates of successful performances in memory test (28.6%) and necrosis of tail end (9.5%) were seen in F1 offspring. At 0.04 and 0.2 mg/kg, no toxic effect on dams and F1 offspring was observed. There were no malformed Fl and F2 fetuses in all groups. The results indicate that the no effect dose levels(NOELs) of DA-125 are 0.2 mg/kg/day for dams and Fl offspring, and over 1 mg/kg/day for F2 fetuses.

  • The structure of water molecules in the pure liquid state has been subjected to extensive research for several decades. Questions still remain unanswered, however, and no single model has been found capable of explaining all the anomalies of water. In the present study near-infrared spectra of water in the temperature region 6-$80^{\circ}C$ have been analysed by use of principal component analysis (PCA) and two-dimensional correlation spectroscopy in order to study the dynamic behaviour of the water band centred at 1440 nm, which is due to the combination of symmetric and antisymmetric O-H stretching modes. It has been found that the wavelengths 1412 and 1491 nm account for more than 99% of the spectral variation, representing two major water species with weaker and stronger hydrogen bonds, respectively. A third species located at 1438 nm, whose concentration was relatively constant as a function of temperature, is also indicated. A somewhat distorted two-state structural model for water is suggested.

  • DA-125, a new anthracycline antitumor antibiotic, was at dose levels of 0, 0.1, 0.3 and 1.0 mg/kg/day administered intravenously to pregnant Sprague-Dawley rats during the organogenetic period. Two-third of dams per group were subjected to caesarean section on day 20 of pregnancy and the remaining 10 dams per group were allowed to deliver. Effects of test substance on dams, embryonal development of Fl fetuses, as well as growth, behaviour and mating performance of Fl offspring were examined. 1. At 1 mg/kg, one out of the 10 dams showed difficult delivery. A decrease in food consumption, a loss in body weight and a decrease of spleen weight were found in this dose level group. At 0.3 mg/kg, difficult deliverys were observed in two out of the 10 dams. 2. At 1 mg/kg, an increased resorption rate and a decreased fetal weight were found. In addition, various types of external, visceral and skeletal malformations occurred at an incidence of 11.9, 41.8 and 14.5%, respectively. 3. At 1 mg/kg, body weight reduction, small eyeball, hydrocephalus and atrophy of sexual organs were observed in Fl offspring. One male pup receiving 0.3 mg/kg died on day 2 of lactation. The results show that the no-effect dose levels (NOELs) for dams and Fl offspring are 0.1 mg/kg/day and NOEL for Fl fetuses is 0.3 mg/kg/day.

  • Since IMF relief financing, domestic economy has been rapidly cooled down. At this point that we predict an overall decrease of production and sale of industries, cooperative marketing activities of the whole dairy industry are required to promote milk consumption. As everyone knows, advertisement is only one of the various factors that affect sales. Other factors include price, distribution, package, promotion, and consumer's needs and taste. The objectives of the cooperative advertising campaign should be trial purchase of new consumers, maintenance of brand loyalty of existing consumers, more positive experience of using the product, and increase of frequency of purchase. Long term analysis is essential to making these kinds of behaviour changes. Also the objectives of the communication program should be a shift of awareness of milk from 'a basic health food for children' to a substitute to the beverage even for adults. To share database of consumers among companies, we need to find ways to use interactive on-line services, the internet, D.M. events and so on as well as the mass media. It should be a precondition that the main body of the cooperative advertisement includes the milk processing board, dairy companies, livestock cooperations, farmers and the Government. To assure continuous, activities to promote milk consumption, the Government should take the lead in legislating 'An enforcement ordinance for milk promotion and research', and seek complementary measures and support to establish the ordinance.

  • Collagen plays a vital role in the maintenance of structure and function of a human body. It has been widely applied in various fields including biomedical, cosmeceutical, food, pharmaceutical and tissue engineering. In the present study, the docking behaviour of type I collagen with 15 different ligands namely hydroxymethylfurfural, methylglyoxal, methylsyringate, O-methoxyacetophenone, 3-phenyllactic acid, 4-hydroxybenzoic acid, kojic acid, lumichrome, galangin, artoindonesianin F, caffeic acid, 4-coumaric acid, origanol A, thymoquinone and quercetin was evaluated along with their putative binding sites using Discovery Studio Version 3.1. Docking studies and binding free energy calculations revealed that origanol A has maximum interaction energy (-40.48 kcal/mol) and quercetin with the least interaction energy (-15.44 kcal/mol) as compared to the other investigated ligands. Three ligands which are galangin, methylsyringate and origanol A were shown to interact with Asp21 amino acid residue of chain B (type I collagen). Therefore, it is strongly suggested that the outcomes from the present study might provide new insight in understanding these 15 ligands as potential type I collagen modulators for the prevention of collagen associate disorders.
