Purpose: This study was done to survey health behaviors in people at risk for a Cerebrovascular Accident(CVA). Method: From November 21 to December 29, 2005, a questionnaire survey was conducted with 171 people at risk for a Cerebrovascular Accident(LDL of above 130mg/dl & homocysteine of above $15.0{\mu}mol/L$). Their physical composition was measured and blood was collected. Results: 1. Of the subjects, 34.5% were smokers, 61.4% were drinkers, 56.7% did not exercise regularly, 57.3% did not control their weight, 26.9% preferred eating meat, and 32.2% preferred salty food. 2. The gender was different between smoking status($X^2=10.734$, p= .001), and drinking status($X^2=7.185$, p= .007), and the age was different between smoking status($X^2=6.656$, p=.010), and drinking status($X^2=10.722$, p= .001). The $HbA_1C$ level was different for regular exercise($X^2=4.824$, p=.028) and the HDL-cholesterol was different for meat-eating preference($X^2=7.928$, p= .005). The observance of troubling signs was different for a salty food preference($X^2=4.313$, p= .038). Conclusion: It is necessary to develop programs for taking care of people at risk for a Cerebrovascular Accident and test the effects of the programs in order to reduce the risk factors of CVA and enhance health behavior promotion.

Purpose: The aim of this study was to prepare and evaluate a natural material extracted from germinated brown rice (GBR). Herein, we evaluated whether the natural material could positively activate the biological effects seen during bone formation, including enhancement of metabolic activity, osteogenesis, and the expression of vascular endothelial growth factor (VEGF), one of the growth factors in human osteoblast-like cells. Methods: The natural material was created by a hot water extraction process after being soaked for 2~3 days in tap water and dried at $50^{\circ}C$. The material was characterized using field emission scanning electron microscopy (FE-SEM), energy dispersive X-ray spectroscopy (EDX), X-ray diffraction (XRD), and Fourier transformed infrared (FTIR) spectroscopy. The biological behaviors of the material were also investigated; we performed tests to assess cell cytotoxicity, metabolic activity, osteogenic markers related to bone formation, and VEGF. Results: The EDX, XRD, and FTIR results for the natural material indicated the presence of organic compounds. The natural material caused positive increases in cell metabolic activity and mineralized bone formation without cytotoxicity. The protein levels in the extract for the $6.25{\mu}g/mL$, $12.25{\mu}g/mL$, $25{\mu}g/mL$, $50{\mu}g/mL$, and $100{\mu}g/mL$ groups were significantly different from that for the control. Conclusions: The GBR-based natural material was easy to prepare and had characteristics of a potential biomaterial. The biocompatibility of this natural material was evaluated using in vitro techniques; our findings indicate that this novel material is promising for agricultural and biological applications.

LBD-001, a recombinant human interferon $\gamma$ produced by genetically engineered yeast as a host system, was administered intraperitoneally to Sprague-Dawley male rats from premating to mating period at least for 60 days and to female rats from at least for 2 weeks before mating to early gestation period (from day 0 to 7 of gestation) at dose levels of $0.35\times10^6, 0.39\times10^6, and 1.38\times10^6$ I.U./kg/day. In the positive control group, ethynylestradiol ($EE_2$; 40 $\mu\textrm{g}$/kg/day) was subcutaneously administered only to female rats during the early gestation period. Effects of the test agents on reproductive performances of the male or female rats and embryonic development were as followings; (1) No significant changes by the treatment of LBD-001 were observed in general behaviors, body weight, food and water consumption, and necropsy of parent animals. However, significant decreases of body weight, food consumption, and water consumption were observed in ($EE_2$ -treated female rats. (2) Mating performances and fertility of parent animals were not significantly affected by the treatment of LBD-001. In ($EE_2$ -treated females, however, the fertility was completely inhibited. (3) No changes in resorption rate and external abnormality of F1 fetuses were observed by the treatment of LBD-001. The results show that LBD-001 at the dose of $1.38\times10^6$ I.U./kg/day or less does not affect general toxicity and reproductive function of parent animals and embryonic development of F1 fetuses.

LBD-001, a recombinant human interferon ${\gamma}$ produced by genetically engineered yeast as a host system, was intravenously administered to pregnant female rats (Sprague-Dawley) from day 7 to 17 of gestation at dose levels of 0.35$\times$10$^{6}$ , 0.69$\times$10$^{6}$ , and 1.38$\times$10$^{6}$ I.U./kg/day. As the control groups, hydrocortisone sodium succinate (5 or 10 mg/kg/day) was also similarly administered. Teratological effects of the test agents on fetuses and development of offsprings (F1 rats) were investigated. (1) No significant changes by the treatment of LBD-001 were observed in body weight, food and water consumption, feeding and nursing behaviors, and autopsy of pregnant or lactating mother rats. However, in hydrocortisone sodium succinate (10 mg/kg/day)-treated group, significant decreases of body weight on day 16, 18, and 20 of gestation and food consumption on day 20 of gestation and outstanding atrophy of thymus and adrenals were observed in two rats autopsied on day 20 of gestation. (2) No significant changes in resorption rate, skeletal or visceral development of fetuses, and physical or sensory development of offsprings (Fl) by the treatment of LBD-001 were detected. In hydrocortisone sodium succinate (10 mg/kg/day)-treated group, however, there were significant decreases of body weight of fetuses, delay of ossification, temporary delay of body weights of offsprings (F1) on day 1 and 3 of lactation, and increased tendency of stillborn rate and malformation rate of bone. The results show that LBD-001 at the dose of 1.38$\times$10$^{6}$ I.U./kg/day or less is not teratogenic in organogenesis of fetuses and the development of offsprings (F1). Meanwhile, hydrocortisone sodium succinate (10 mg/kg/day) seems to delay ossification of fetuses and temporarily retard the development of offsprings (Fl).

The purpose of this study was to investigate the characteristics of dining-out customers by their behaviors based on geographical regions and visiting days in relation to restaurant attraction at ski resorts in Korea. The data were collected from six ski resorts. Three of the ski resorts were located in Kyunggi Province close to a metropolitan area, namely Seoul. The other three resorts were located in Kangwon Province, which is considered to be distant from the Seoul metropolitan area. A total of 599 usable questionnaires were utilized in the data analysis. Descriptive statistics and a cross tabulation analysis with chi square were used to examine the demographic characteristics of the respondents and the significant differences between geographical regions as well as between weekdays and weekends. The responding customers consisted of 57.3% (n=343) males and 42.7% (n=256) females. With respect to age, 15.5% were less than 20 yr., 44.6% were $20{\sim}30$ yr., and 28.0% were $30{\sim}40$ yr. The most recognizable occupations were student (32.9%) followed by office worker (33.2%). Twenty-seven percent of the respondents had less than one year of skiing experience and the majority (32.9%) had more than $1{\sim}3$ yr of experience. The major findings obtained from this study include statistically significant differences in the customers' demographical characteristics of age, occupation, skiing experience, and residential area according to the geographical regions of Kyunggi Province and Kangwon Province (p<0.05). All six of the customers' behavioral attributes, including transportation, reason to visit, staying days, purpose of visit, spending expenses, and usage of discount programs, showed significant differences between geographical groups (p<0.05). Finally, restaurant attraction was associated with the purpose of visiting and spending expenses by customers at the ski resorts (p<0.001).

This study was conducted to assess the effects of nutrition label education in children. The students of three randomly selected sixth-grade classes at an elementary school participated, were classified into a control group, an indirect (written message to parents) education group, and a direct (teaching children) education group. Nutrition label education was conducted in the latter two groups but not in the control group. There were no significant differences between pretest and posttest scores for nutrition knowledge or in the dietary attitudes of the control group and indirect education group. Improvements in test scores for nutrition knowledge and dietary attitudes were observed only in the direct education group. There were significant positive changes in the indirect and direct education groups, such as selecting snacks (cookies) by considering the fat content. Moreover, after the lessons, the percentage of children who chose white milk (regular milk, calcium-enriched milk, and low-fat milk) significantly increased in the direct education group. This study suggests that conducting nutrition label education helps children improve their nutrition knowledge and leads to positive changes in dietary attitudes and eating behaviors. In particular, a direct nutrition education method is more effective than an indirect method such as a written message to parents. Therefore, it is suggested that systematic and constant 'nutrition label education' be performed by nutrition teachers in elementary schools to establish healthy eating habits based on choosing nutritious snacks and processed foods.

The purpose of this study was to examine the ethical attitudes of consumers in consumption situations by using the consumer ethics scale(CES). Self-administrated questionnaires were completed by 492 consumers, and the resulting data were analysed by frequency, chi-square, one-way ANOVA, factor analysis, reliability analysis, and cluster analysis. We found four different groups of consumers were identified according to their ethical attitudes in consumption situations: 1) the unethical onlooker consumer group, 2) the socialized unethical consumer group, 3) the ethical consumer group, and 4) the severely unethical consumer group. The unethical onlooker consumer group was most widespread prevalent among university students who were in their 20s and down or under, and who received spending money from their parents, and the socialized unethical consumer group was most prevailing prevalent among the higher educated consumers. The women who consumers slightly outnumbered men in an the ethical consumer group, slightly outnumbered the men who did, and many of the university-educated large income earners fell into this group consumed in that way as well. The severely unethical consumer group was quite uncommon among those who were at the age of 41 and up over, and not many of the higher educated people and larger income earners consumed in an the severely unethical consumer group, either. Thus, it's proven this study proves that in terms of the propensity to consume, the consumers' were different from one another in ethical attitudes and behaviors differ according to their demographic characteristics.

This study was conducted in order to compare weight control behaviors, eating disorder risk, and depression in female adolescents according to dieting experience during the last year. The subjects were 707 students attending a girls' high school in Seoul, and all the information was collected by self-administered questionnaire. Eating disorder risk and depression were determined by using EAT-26 (Eating Attitude Test-26) and PHQ-9 (Patient Health Questionnaire-9), respectively. Data were compared between subjects with experience of dieting (320) and those without (387). More of the subjects with dieting experience were unsatisfied with their own body weights (76.9% vs. 44.2%, P<0.01) and weighed themselves frequently (P<0.01) compared to those without diet experience. EAT-26 ($11.63{\pm}8.3$ vs. $5.99{\pm}4.7$, P<0.01) and PHQ-9 scores ($7.05{\pm}4.6$ vs. $6.00{\pm}4.4$, P<0.01) were higher in subjects with dieting experience compared to their counterparts. Therefore, we concluded that dieting is associated with several undesirable psychological aspects such as eating disorder risk and depression in adolescent girls, and thus providing proper education is urgently needed to emphasizing importance of healthy weight and the danger of unnecessary dieting.
