The principal objective of this study was to provide basic data regarding health care services for middle-aged men, via an analysis of the relationships among stress level, food habits and well-being-related attitudes with social-demographic characteristics and health-related factors. The main findings of this study were as follows. The average age of the participants was $48.7{\pm}5.2$. With regard to health status, 18.8% of the participants were diagnosed with digestive diseases within the past year. Stress levels were higher in the participants with lower levels of educational attainment. Furthermore, participants who had become divorced or lived separately from their families, participants who did not have their own houses, and participants who reported low marital satisfaction also had high levels of stress. Our food habits scores revealed meaningful differences among the study subjects, and were shown to vary with marital satisfaction, occupation, and residence type. In terms of both the importance and practice level of well-being-associated food habits, the most frequent response in this study was 'Consume home-made food rather than processed or ready-to-eat food' ($4.30{\pm}0.86$, $3.68{\pm}1.04$). In terms of importance level, the factors most relevant to well-being in terms of food habits were education level, marital satisfaction, residence type, self-assessed health status, smoking, drinking, regular exercises and leisure activities. With regard to practice levels, the degree to which subjects engaged in food habits targeted toward well-being differed meaningfully depending on marital status, marital satisfaction, residence type, family type, self-assessed health status, smoking, drinking, nutritional supplement intake, regular exercises and leisure activities. After analyzing the correlation among stress level, food habit score and the attitude towards well-being-related dietary habits (importance and practice level), we observed a meaningful relationship between the four factors at the level of p<0.001. According to the above result, continuous attention to health, including the appropriate control of smoking and drinking, as well as, stress management, via regular exercises and appropriate food habits is expected to exert a positive influence on the prevention of disease, and is also expected to improve quality of life. For all well-being-associated items, the importance level was shown to be higher than the practice level. Thus, in order to foster health-oriented food habits, we recommend that a new plan be designed, targeted toward ease of active practice for middle-aged men.

유기산으로 분해된 카라기난 가수분해물의 각종 생리활성을 실험한 결과, citrate와 malate를 가수분해 매체로 이용할 경우, $100^{\circ}C,\;110^{\circ}C$ 및 $120^{\circ}C$ 가수분해물은 B. cereus와 B. subtilis에 강한 항균활성을 나타내었으며, $120^{\circ}C$에서 180분간 가수분해한 것이 B. subtilis에 대해 특별히 강한 항균활성을 나타내었다. 그러나 충치균인 St. mutans에 대한 항균활성은 없는 것으로 확인되었다. Tyrosinase 활성 저해 효과는 $100^{\circ}C$ 및 $120^{\circ}C$에서 처리된 시료 중에서 citrate와 malate 처리구가 97% 이상의 높은 tyrosinase 활성을 저해하는 것으로 확인되었다. Citrate로 $100^{\circ}C$에서 90분 처리된 시료의 경우 97.1%, 180분 처리된 것은 99.4%의 저해 활성을 나타내었고, $120^{\circ}C$에서 90분 처리된 시료의 경우 98.2%의 tyrosinase 활성을 억제하는 것으로 나타났다. 한편, malate 처리구도 처리온도와 처리시간에 따라 약간의 차이는 있지만 전체적으로 citrate 처리구와 비슷한 결과로 $98{\sim}99.5%$의 높은 tyrosinase 활성 저해 효과를 나타내었다. 당질 농도에 따라 tyrosinase 활성 저해 효과가 다르게 나타났으며, 환원당 및 전당의 농도에 비례하는 것을 확인할 수 있었다. 항혈액응고활성은 유기산의 종류에 따라 차이를 나타내고 있는데, 0.3% malate 용액으로 $80^{\circ}C$에서 180분간 처리 시료의 경우 APTT가 $2,451{\pm}18(sec)$로 항혈액응고활성이 가장 높았으며, 동일한 조건에서 얻어진 0.3% citrate 가수분해물이 $1,617{\pm}15(sec)$였으며 lactate, succinate, acetate 가수분해물 순으로 높았다. 가수분해가 진행됨에 따라 분자량이 적어지고 결국은 황산기 함량도 낮아지게 됨으로써 항혈액응고활성이 낮아지는 것으로 여겨졌다.

두께 1 mm의 감자 절편을 분자량 200에서 6000까지의 PEG용액에 침지했을 때 PEG의 분자량이 작을 수록 초기 탈수 속도가 빨랐으나 최종 탈수량은 PEG 분자량이 클수록 증가하여 PEG 6000인 경우 초기수분의 약 80%까지 탈수되었다. 감자절편을 저분자 용액인 NaCl, PEG400 용액에 침지한 경우, 조직의 뒤틀림 현상은 나타나지 않고 plasmolysis가 일어나면서 탈수와 부피가 감소되는 반면, PEG 600 용액에 침지시부터 조직의 뒤틀림 현상이 동반된 탈수 현상이 나타났으며, 고분자 용액인 PEG 4000 용액에 침지한 경우 cytonhysis 현상을 동반한 탈수와 부피 감소가 더욱 분명하게 관찰되었다. 초기 탈수 속도는 저분자 용액에 침지 시 더 빨랐으나 최종 탈수량은 고분자용액에 침지 시 더 컸으며 탈수량이 역전되는 시기는 cytorrhysis가 일어나는 시기와 일치하였다. 따라서 고분자 용질의 고농도 용액에 시료를 침지하면 용질의 함침량은 적게 하면서 탈수량을 증가시킬 수 있음을 알 수 있었다.

The purpose of this study was to analyze the food-related lifestyle choices of female baby boomers and to investigate variables regarding home meal replacement (HMR) buying behaviors and future needs. This study was conducted on 358 female baby boomers 53 years of age living in Gyeonggi and near Seoul. Out of 420 distributed questionnaires, 358 were returned and used for analysis (response rate: 85.2%). As a result of cluster analysis, three groups were identified based on the food-related lifestyles : a value-seeking group, a convenience-seeking group, and a health-seeking group. Among the three groups, there were significant differences in two socio-demographic characteristics, education level (p<0.05) and regular exercise (p<0.01), and in several health- and food-related habits, type of breakfast (p<0.01), type of dinner (p<0.05), dinner details (p<0.05), frequency of eating out (p<0.05), and eating habits score (p<0.01). The health-seeking group was significantly more likely to purchase ready to cook (RTC) items (59.1%) than were the other groups (p<0.001). However, the ratio of HMR purchasing for the purpose of meal replacement (p<0.05) and an HMR purchasing frequency of more than twice a week (p<0.001) were significantly lower in the health-seeking group. Reasons for selecting HMR showed a similar tendency among groups in taste (26.2%), convenience (18.7%), price (16.9%), safety (15.3%) and type of food (14.3%). However, the satisfaction scores for hygiene and safety reported by the health-seeking group were significantly lower than those reported by the other groups. More than two-thirds of all respondents were willing to purchase HMR in the future, though there were significant differences according to group: convenience-seeking group, 73.1%, health-seeking group, 70.1%, and value-seeking group, 65.7% (p<0.05). Our results suggest that the number of baby boomers purchasing HMR products will continue to grow and baby boomers will want HMR products to be more healthy (52.0%), safe (28.5%) and delicious (13.4%). An emphasis on taste was high in the convenience-seeking group, whereas an emphasis on health was high in the health-seeking and value-seeking groups. In conclusion, this study shows various food-related lifestyles amongst female baby boomers and illustrates the need to develop HMR marketing strategies targeted to these different lifestyles.

The purpose of this study was to examine the levels of satisfaction, and awareness, as well as evaluations of internship programs between major and non-major students in food and nutrition. The survey was conducted via questionnaire to 80 major and 113 non-major students in food and nutrition who had finished an internship. For the primary internship facilities, the proportions were 51.3% in foodservice for the major group and 57.4% in business & industry for the non-major group. For the internship period, the proportions were 71.2% for under 2 weeks in the major group, and 42.9% for $2{\sim}4$ weeks in the non-major group(p<0.001). The proportions of students who were provided orientation from a professor(p<0.001), and visiting guidance by a professor(p<0.001), were 40.5% and 35.4%, respectively, in the major group and 73.4% and 82.1 %, respectively, in the non-major group. The proportions answering that the internship was a necessity were 95.0% in the major group and 75.2% in the non-major group(p<0.001). The major group had significantly higher satisfaction scores for location of the internship facility, internship period, and connection between education and practice as compared to the non-major group. However, the satisfaction score for professor's guidance during the internship was significantly lower in the major group than the other group. The evaluation score for 'I did my best when doing my work' was significantly higher in the major group than the non-major group. The major group had significantly higher awareness scores for the internship's degree of assistance in improving skills, making use of knowledge, and adapting to the field, as compared to non-major group. In conclusion, students majoring in food and nutrition faithfully participated in their internship programs, with higher degrees of satisfaction and awareness, and higher evaluations. However, more effective internship program with intensified and developed guidance by professor are needed.

This research focused on the effects of adding Hizikia fusiforme to Jeolpyun. We were able to demonstrate in this study that Jeolpyun after the addition of Hizikia fusiforme had the potential to become a functional food. Jeolpyun with 0, 2, 4, 6, and 8% of Hizikia fusiforme was analyzed by water content, color, sensory and textural characteristics immediately after production and one day later. The five different types of Jeolpyun did not show any significant differences in water content. However, all the Jeolpyun with Hizikia fusiforme showed slightly higher water retention ratio than the control after storage. As the result of Hunter's color values, lightness decreased significantly as the amount of Hizikia fusiforme increased. Redness increased in the Jeolpyun with Hizikia fusiforme compared with the control. Yellowness was highest in the Jeolpyun with 2% of Hizikia fusiforme and decreased with an increase in its content. In the textural analysis, hardness, chewiness, adhesiveness and gumminess of Jeolpyun with 2% and 4% of Hizikia fusiforme were similar to those of the control, whereas springiness of Jeolpyun with 2%, 4% and 6% of Hizikia fusiforme were similar to that of the control group. Cohesiveness significantly decreased as the amount of Hizikia fusiforme increased. When the Jeolpyun was preserved for one day, all five Jeolpyun showed significant increases in hardness, gumminess and chewiness. However, their adhesiveness significantly decreased. Cohesiveness decreased in all Jeolpyun except for the 8% Jeolpyun. In sensory evaluation, color and aroma became stronger as the content of Hijikia fuziforme increased, and 2% Jeolpyun showed similar hardness with the control. Jeolpyun with Hijikia fuziforme showed no difference in cohesiveness with the control, but the adhesiveness showed a little increase when compared to the control. The overall acceptability of 2% Jeolpyun showed slightly higher than control. After one day of storage, Jeolpyun with 2% of Hijikia fuziforme also showed the highest overall acceptability. And the overall acceptability showed the biggest decrease in the control group. Overall acceptability showed strong negative correlation with color, aroma and hardness, and showed strong positive correlation with cohesiveness and adhesiveness. After one day of storage, overall acceptability showed a decrease in correlation with color and smell and an increase in correlation with cohesiveness, compared to before storage. Results of multiple regression analysis showed that hardness had the biggest influence(-) on the overall acceptability of Jeolpyun, aroma and cohesiveness ranked second(-) and third(+) respectively. After one day of storage, cohesiveness had the biggest influence on the overall acceptability of Jeolpyun. Color and adhesiveness ranked second(-) and third(+) respectively. It can be seen that different factors influence overall acceptability of Jeolpyun after storage.

The purpose of this study is to examine female baby boomers' dietary habits and their attitudes together with their needs for future perspectives of dietary life. Our aim is to use these findings as a basic data when forecasting for food-related industries or policy making. A survey is being carried out for a total of 358 female baby boomers and analyzed by SPSS 12.0. The following is a summary of this study. The average age is 52.6 years old, most of them graduated from highschool (63.1%) and had a nuclear type of family (76.1%). Only 39.0% is composed of housewives, others had either full-time or part-time jobs. Self-assessment of stress is not so high and only 8.1% are dissatisfied with their lives. 38.2% are either overweight or obese in terms of BMI, and most of them are non-smokers (97.2%) or non-drinkers (63.0%). Their mean dietary habit scores are $70.6{\pm}11.8$, and the scores show significant relations with their education levels (p<0.01), monthly income (p<0.01), life satisfaction rates (p<0.001), stress levels (p<0.001), smoking habits (p<0.05), drinking habits (p<0.05), regular exercises (p<0.001) and regular health check-ups (p<0.05). The rate of skipping breakfast, lunch and dinner are 18.2%, 1.1%, 5.2% respectively. The main reason for skipping breakfast is the 'lack of time'. With regards to the frequency of grocery shopping, almost half of the subjects (55.7%) said '1~2 times per week' and bought mainly raw food sources such as vegetables, fruits, and meats. The majority of the subjects (91.3%) report that they cooked meals at homes, and took about 1 hour of time. The subjects also point out that cooking was a bothering task, and only 46.4% would prepare meals at home, while others would rather eat out or eat convenience foods. The main reasons for not wanting meal services in the elderly welfare facility are because they didn't want to live such places (48.4%) and the meals are tasteless (31.3%). As for delivery meal services, 60.1% are aware of it, and 39.9% would consider using it in the future. Factors to be considered when using the delivery meal service are sanitation (43.7%), nutrition (28.7%), taste (18.4%), price (6.3%), and brand name (2.9%). This study is expected to be used as useful information when developing food-related strategies for baby boomers in the future.
