The purpose of this study was to investigate the perception and willingness to purchase of nanotechnology-based foods to find out the strategy for risk communication and social acceptance. The data were collected from 253 college students in Yeungnam region through a self-administered questionnaire. Frequency, Cronbach's ${\alpha}$, t test, one-way ANOVA, Duncan's multiple range test, Pearson's correlation coefficient analysis, and multiple regression analysis were conducted by SPSS Windows V.20.0. The level of concern about nanotechnology was relatively low, and the level of the perception about necessity for the development of nanotechnology-based foods was average. In addition, the respondents showed somewhat positive thoughts for the development of nanotechnology-based foods with beneficial effect, but they were worried about the risk for it. Percentage of correct answers on knowledge of nanotechnology and nanotechnology-based foods was not high, and the level of willingness to purchase them was average. According to the result of multiple regression analysis, factors affecting the willingness to purchase of nanotechnology-based foods were concern about health, perception about importance of food safety, perception about necessity for the development of nanotechnology-based foods, and perception about the development of nanotechnology-based foods with beneficial effect. On the basis of these results, it is necessary for consumers to offer the exact and reliable information on nanotechnology-based foods.

This study was conducted to investigate the changes in alcohol consumption of male university students in Daegu, Korea and their drink-related behavior. The study focused on these changes over a decade using self-administered questionnaire surveys and health examinations that were carried out at a university campus in 1999 and in 2009. In both years more than 85% of students responded that they drank alcohol. However, significant increases in the frequency and amount of alcohol consumption were found (p<.001). The main influence on students' drinking behavior was friends/peers in both years. The most frequently preferred alcohol of respondents was so-ju (a traditional Korean liquor) in both years. However, the most frequently preferred type of food to accompany drinking had significantly changed (p<.01). Other changes including the increase of drinking speed and smoking during drinking were found to have significantly changed (p<.05) while significant difference regarding the decrease in food intake during drinking was not found. No significant difference in the amount of alcohol consumed was noted between underage drinkers and drinkers of above the legal drinking age. Heavy drinkers in the 2009 population had significantly higher systolic blood pressure than non-drinkers and moderate drinkers (p<.01). This study also indicates that there may be a rise in heavy drinking and/or binge drinking among drinkers including underage students. The results of this study suggest that alcohol-blood pressure associations are considered to be of concern even in young adults. This study also suggests the need for special alcohol prevention programs or campaigns to intervene in the behavior of students.

Adverse drug reaction (ADR) may increase hospital admission, morbidity and mortality and adding extra cost to healthcare expenditures. AIMS: This study was performed to identify the types of ADR being reported in a tertiary hospital, and to find out the ways to improve current ADR monitoring system. To investigate the attitudes of hospital pharmacists towards, and their understanding of ADR reporting. METHODS: Of 117 reports submitted to the pharmacy department during 3 months survey period, A questionnaire survey of 75 randomly selected hospital pharmacists was conducted. RESULT: Of the report was from patients aged between 60 and 70. The medical department with the high frequency in ADR reporting was Internal Medicines $(60\%)$. The most common ADR manifestations were gastrointestinal complaints $(47.8\%)\;and\;80\%$ of the reported cases were mild in their severity. The most common drugs suspected of causing ADR were CNS drugs which accounted for $38.4\%.\;55.5\%$ of respondent were aware of the need to education and information about ADR monitoring. The important reasons for unreporting ADR were unknown of how to report ADRs $(94.6\%)$. CONCLUSIONS: An ADR reporting system based on reporting by staff pharmacists has been effective increasing the number of reported reactions and pharmacist involvement in monitoring patients for ADRs. Pharmacists have the knowledge and responsibility to contribute to ADR reporting program. A great opportunity exists for pharmacists to contribute in this area of patient care.

Dietary pattern analysis is important complementary approach for identifying associations between diet and chronic disease. A case-control study was conducted in order to examine dietary patterns and the risk of colon cancer in Korea. Data were collected from both 137 cases with either colorectal cancer or large bowl adenomatous polyps and 134 controls regarding social-demographic characteristics and food intake using a semi-quantitative food frequency questionnaire. We conducted factor analysis and identified 6 major dietary patterns: 'Well-being diet' characterized by higher intakes of potatoes, yogurt, soybean paste and vegetables, 'Meat & fish', 'Milk & juice', 'Pork & alcohol', 'Rice & kimchi', and 'Coffee & cake'. We calculated factor scores for each participant and examined the associations between dietary patterns and colon cancer risk. After adjusting for potential confounders, there was a relative risk for colon cancer of 0.16 (95% confidence interval, 0.07 - 0.34) when comparing the highest with the lowest tertile of the 'Well-being' pattern. Significant trends of decreasing risk of colon cancer also emerged with the 'Milk & juice' (OR = 0.40, 95% CI = 0.20 - 0.79). In contrast, inverse associations of the risk were found for 'Pork & alcohol' (OR = 1.92, 95% CI = 0.93 - 3.97), 'Coffee & cake' (OR = 2.18, 95% CI = 1.07 - 4.46). For the 'Meat & fish' pattern, the decreased risk of colon cancer was observed in the second tertile, but not in the highest tertile when comparing to the lowest. The 'Rice & kimchi' pattern had a nonsignificant association with the risk. These data suggest that major dietary patterns derived from the FFQ associated with the risk of colon cancer in Korea. Since foods are not consumed in isolation, dietary pattern research in natural eating behavior may be useful for understanding dietary causes of colon cancer.

The purpose of this study was to investigate the intakes and perceptions of convenient breakfast related to age and family type. The survey included 545 men and women living in Seoul from June to July. Questionnaire items covered their age, gender, family types, breakfast intakes and preference for convenient breakfast menu. As a result, there were significant differences in the number of breakfast intakes per week according to family types; large families recorded the highest frequency in "I have breakfast everyday" and the couple-only families and nuclear families scored relatively high numbers. In terms of the type of breakfast, the first choice was "rice and side dishes" across all the age groups (69.3%). There were differences in the preference of convenient breakfast in "bread", "cereal", "rice cake", "sunsik", and "rice gruel" by different age. The teens exhibited the highest preference of bread (5.63), and cereal (5.53) for breakfast; those who were in their fifties for rice cake (5.42). Both forties and fifties showed the higher preference of sunsik (4.58, 4.76) and rice gruel (5.89, 5.77) than other age groups. As for the preference for convenient breakfast according to family types, single person families displayed the highest preference of bread (5.42) and cereal (5.75). Couple families showed higher preference of rice gruel (5.82) than other family groups. The preference level for "rice cake" was similar among all the family types. As a result, it is suggested that the development of various breakfast menus considering age groups and family types is needed so that modern people can enjoy breakfast in terms of quality and quantity in their busy daily life.

This study examined salty taste acuity and salty taste preference and sodium intake in relation to zinc nutritional status in 2 rural populations in Korea. And we also examined the main food contributors of their sodium intakes. We enrolled 218 adults (66 men and 152 women) from the Kangneung and Samcheok regions in Korea's Kangwon province in our study conducted from December 2011 to February 2012. Participants from each region were divided into 3 groups based on their serum zinc level (T1: lowest, T2: intermediate, T3: highest). We compared the salty taste acuity and preference, Na index (Dish Frequency Questionnaire for estimation of habitual sodium intake), blood pressure, and intakes of nutrients including sodium by 3 groups of serum zinc level. The results were as follows: a higher serum zinc level indicated a lower sodium intake and Na index (P<0.05). The salty taste acuity was considerably higher for participants from the Kangneung region than those from the Samcheok region (P<0.05). And the serum zinc level was significantly higher in participants from the Kangneung region than those from the Samcheok region (P<0.05). We further divided the participants into 2 groups: those who consumed more zinc than the recommended intake (RI) and the others. We compared salty taste acuity and salty taste preference in the 2 groups. The salty taste threshold and palatable salty taste concentrations were lower for the group with a zinc intake above RI than for the group with zinc intake below the RI. However, the difference was not significant. This study confirms that taste function differs depending on zinc nutritional status. In future, it is required to a large-scale, long-term, prospective study on the correlation between zinc intake, serum zinc levels, and taste perception function and blood pressure.

The prevalence rate of thyroid dysfunction (hypothyroidism and hyperthyroidism) has increased within the Korean population and seems to be affected by iodine dietary habits. Some studies reported that the prevalence of thyroid dysfunction increase both in the area of iodine deficiency and excess. In this study, we tried to discover the difference in iodine intake, anthropometric measurements, and blood parameters between male subjects with or without subclinical thyroid dysfunction. A total of 5,249 subjects (Euthyroid: 4706, SubHypo: 454, SubHyper: 89) were used in this study. There were no significant differences in BMI, body fat, visceral fat, waist circumference, SBP, DBP, total cholesterol, HDL-cholesterol, LDL-cholesterol, TG, fasting serum glucose, HbA1c, alcohol intake, however significant differences were noticed in both age and smoking status. Through a food frequency questionnaire (FFQ), iodine intake per day was estimated. The average iodine intake was similar (SubHypo $392.9{\pm}279.0{\mu}g$, Euthyroid $376.5{\pm}281.7{\mu}g$, SubHyper $357.3{\pm}253.8 {\mu}g$) among groups. The main source of iodine intake was eggs (52.8%, 54.2%, 52.4%) followed by milk (16.3%, 15.8%, 17.8%), then sea mustard & sea tangle (12.4%, 11.9%, 11.6%). The prevalence of subclinical hypothyroidism and subclinical hyperthyroidism was higher in subjects whose intake was higher than the recommended nutrient intake (RNI). These results suggest that the excess consumption of iodine intake may act as one of the risk factors regarding thyroid dysfunction in Korea. Therefore, an adequate amount of iodine intake is necessary in order to prevent subclinical thyroid dysfunction and clinical thyroid dysfunction.

The study was carried out to investigate housewive's consumption pattern and preference of mayonnaise for the development of egg-white mayonnaise. Data was collected from 515 housewives in Ulsan by self-administered questionnaire. The collected data were analyzed by SPSS package program. The results were as follows: 1. Most(98.1%) of housewives were concerned about nutrition and health and they considered that nutrition was the most important factor when purchasing food related items. 2. The frequency of using processed foods was two to three times a week and the reason for use it was the convenience. Usually the housewives obtained nutrition related information through mass media such as TV, radio(37.5%) , and newspaper, magazine(32.1%). 3. 75.9% of the subjects thought mayonnaise is a high calorie food and 57.5% of them knew the basic ingredients of mayonnaise. Most(79.3% ) of housewives perceived that cholesterol which is rich in egg yolk is related to cardiovascular disease and arteriosclerosis. Among family members, children showed high degree in the preference for mayonnaise. 4. Comparison of the low cholesterol mayonnaise which was made by egg white for egg yolk with commercial product was made by sensory evaluation and mechanical test. The viscosity and turbidity did not show any difference. Overall taste of low cholesterol mayonnaise was better than of commercial product. Based on these results of this study provided useful information for development of egg-white mayonnaise (low-cholesterol mayonnaise) and expected the possibility of using low cholesterol mayonnaise will be high.
