This study was performed to evaluate the differences in blood pressure, sodium intake and dietary behavior changes according to the extent of session attendance on sodium reduction education program for pre-hypertensive adults in a public health center. Sodium reduction education program consisted of 8 sessions for 8 weeks. Fifty three patients who completed the pre and post nutritional assessments were classified into 2 groups according to the session attendance rate. Nineteen participants who attended the education program 3 times or less (${\leq}3$) were categorized into the less attendance (LA) group and 34 participants attended 4 times or more (${\geq}4$) into the more attendance (MA) group. Blood pressure, anthropometric measurements, serum lipid profile, nutrient intakes including sodium, nutrition knowledge and dietary behavior score were assessed before and after the nutrition education program. Mean sodium intakes (p<0.001), systolic/diastolic blood pressure (p<0.001), and weight (p<0.001) were significantly decreased in the MA group after sodium reduction education program. Compared to the MA group, mean sodium intakes, systolic/diastolic blood pressure were not significantly changed after the education program even with significantly increased nutrition knowledge (p<0.05) and dietary behavior score (p<0.01) in the LA group. It appears that pre-hypertensive adults need to attend the sodium reduction education program for at least 4 times or more to gain beneficial effects from the intervention. Positive feedback of healthcare team or offering more cooking classes may be needed to raise the attendance rate in the sodium reduction education program.

A menu labeling initiative is a lawful regulation with an aim to promote public health by providing customers the right to make informed menu choices. As college years are a critical period in which students form dietary habits, which are sustained throughout their lives, provision of nutritional information at the university dining services is important to students' health and life. Due to the lack of research on menu labeling at university dining services, the purpose of this study was to examine college students' attitudes and motivations toward menu labeling at university dining services, as well as their use intentions toward nutrition information at university dining services. Data were collected from a self-administered survey distributed to 484 college students who had experienced university dining services. Motivations of university students toward menu labeling were categorized into 'knowledge pursuit' and 'health pursuit'. Students' attitudes toward menu labeling had a positive effect on their intention to use menu labeling at university dining services. The findings of the study indicated that female students, or those who frequently used nutrition information, tended to have higher attitudes, motivations, and use intentions toward nutrition information. The study results suggest that facilitation of healthy eating environments at university dining services by offering nutrition information, and nutrition and health education is necessary.

This study was designed to investigate dietary life related to sodium of participants in hypertension and diabetes preventive education at the public health center located in Incheon Metropolitan City. Subjects were comprised of 301 adults (males: 102, female: 199) of age 50 years and above. The questionnaire for dietary life and salty taste assessment were performed on the subjects. Data were analyzed using SPSS package (ver. 18.0). According to the result of questionnaire for dietary behavior, 70% of the subjects were in the low salt intake group (p<0.001). In the result of questionnaire for dietary frequency, all ages groups were in the low salt intake group (p<0.01). The data of questionnaire for dietary behavior showed that the subjects of age above 75 years preferred salted seafood, soup, and kimchi (p<0.01). The data of questionnaire for dietary frequency showed that the subjects of age between 65 and 74, least chose fried kimchi, noodle, and soybean paste soup with clams (p<0.05), and the healthy adult groups chose kimchi stew, ssam and ssamjang (p<0.05). The score for dietary behavior in male subjects was higher than female subjects (p<0.01). In particular, the score for dietary frequency was the lowest in the subjects of age between 65 and 74 (p<0.01). The mean value of salty taste assessment in the subjects was 0.41% which is higher than the ideal value of 0.3% (p<0.01). Offering more nutrition education and continuous feedback of healthcare center may be needed to improve the health status of the adults.

The objective of this study was to compare the healthy dining out attitude of restaurant diners by self-rated health status. Using healthy dining attitude and behavior questionnaire and a single question describing self-rated health status, the needs and importance of healthy dining out was detected. Mean age of the 182 respondents was 38.9${\pm}$11.37 years old and 37.4% of the respondents answered their mean monthly income was over 6,000,000won showing the subjects belonged in high income diners. The needs of healthy dining measured by five scales and offering healthy menus(3.80), labeling foods about original country(3.79), using environmentally friendly foodstuffs(3.71) and labeling nutrients on menu board(3.62) show higher score than others. A total of 76.4% of the respondents assessed their health status as 'good-rated Health' and 23.6% was 'poor-rated health'. There was no difference in frequency of eating out by self-perception of health status but, the 'poor-rated health' group need more nutrition information in restaurant specially for calorie(p<0.05), cholesterol(p<0.05), fiber(p<0.05), functional nutrients(p<0.001) showing significant differences comparing to 'good-rated health' group. In good-rated health group, selection of Korean cuisine for eating out was more frequent than the poor. The results shows the needs of healthy dining can be varied by diner's health status and therefore restaurateur should focus on understanding of the needs of diners with various health status.

The meats of tuna Thunnus albacares and swordfish Xiphias gladius are ideal for fish patty production, offering high nutrition and other health benefits. Although red fish meat, including tuna, is added for cost-effectiveness, swordfish white meat is also used, as its aroma resembles that of market-sold beef patties. Here, we assessed the different blending ratios of tuna red meat and swordfish white meat (60:40, 40:60, 20:80, and 0:100) to find the optimal combination for fish patty production. Regarding color, the heated fish patties exhibited increased redness (a*) and yellowness (b*) compared with those of non-heated ones, with similar brightness (L*). The heated patties also scored higher concerning hardness, springiness, gumminess, and chewiness. A higher proportion of swordfish white meat resulted in a softer texture, particularly in patties with a ratio of 40% red meat to 60% white meat. Considering the results of the texture comparison analysis, it is recommended that the texture be improved by increasing the physical property "softness." Sensory evaluations revealed that the addition of white meat led to increased scores in terms of smell, beef taste, texture, and elasticity. These results suggest that swordfish white meat, with improved overall quality, is a suitable raw material for fish patties. Accordingly, the recommended ratio of 20% tuna red meat to 80% swordfish white meat is optimal for fish patty production.

This study was conducted to investigate traditional Kyunggi area Korean foods suitable for standardization and commercialization as well as to investigate the perceptions of experts about these foods, and to analyze the important value factor characteristics according to classified traditional food groups by residents of the Kyunggi(n=104)areas of Korea. We determined the degree of value of various traditional foods by asking respondents to 13 items based on a 5 point Likert scale, and used the total scores of the items to determine their value. Based on the results of the total scores and frequently chosen foods, we attempted to select the foods suitable for standardization and commercialization. The results are summarized as follows. For main dishes Ogok-bap was selected as the primary suitable for standardization and commercialization. Next were Incheon yeong yang bap, Hobak-beombek, Hobak-juk, Gesungpyeonsu, Tteokguk, Kimchibap, Kimchimandu, and bap, respectively. Of the side dishes Bossam-kimchi was selected as the primary suitable food for standardization and commercialization followed by Bindaetteok, Sondubu, Samgyetang, Baekkimchi, Doenjang-jjigae, Suwongalbi, Japchae, and Cheonggukjang-jjigae, respectively. Finally, for favorite foods, Duteop-tteok was selected as the primary food suitable for standardization and commercialization. Next were Jeungpyeon, Yakgwa, Yaksik, Maejakgwa, Ssuk-tteok, Yeongeunjeonggwa, Songpyeon, and Osaekdasik, respectively. This study shows that a resident's evaluation of a traditional Kyunggi Korean food is affected by the their sense of value of the food, as well as by the social structure, which includes the population, economic condition, food policies, industrial technology, and culture. This research was conducted to preserve traditional Kyunggi Korean foods and to improve this area's regional income from the prospect of sellable goods. We expect that this research to be used as basic data in the development of new commercial traditional foods by the food industry, by offering a better understanding of diverse consumer sense and to also be used with dietary education data relative to following traditional meal patterns for diverse age groups.

Functional feeding groups (FFGs) of benthic macroinvertebrates are guilds of invertebrate taxa that obtain food in similar ways, regardless of their taxonomic affinities. They can represent a heterogeneous assemblage of benthic fauna and may indicate disturbances of their habitats. The proportion of different groups can change in response to disturbances that affect the food base of the system, thereby offering a means of assessing disruption of ecosystem functioning. In this study, we used benthic macroinvertebrate communities collected at 650 sites of 23 different water types in the province of Overijssel, The Netherlands. Physical and chemical environmental factors were measured at each sampling site. Each taxon was assigned to its corresponding FFG based on its food resources. A multilayer perceptron (MLP) using a backpropagation algorithm, a supervised artificial neural network, was applied to evaluate the influence of environmental variables to the FFGs of benthic macroinvertebrates through a sensitivity analysis. In the evaluation of input variables, the sensitivity analysis with partial derivatives demonstrates the relative importance of influential environmental variables on the FFG, showing that different variables influence the FFG in various ways. Collector-filterers and shredders were mainly influenced by $Ca^{2+}$ and width of the streams, and scrapers were influenced mostly with $Ca^{2+}$ and depth, and predators were by depth and pH. $Ca^{2+}$ and depth displayed relatively high influence on all four FFGs, while some variables such as pH, %gravel, %silt, and %bank affected specific groups. This approach can help to characterize community structure and to ecologically assess target ecosystems.

Fast and dynamic biochemical, enzymatic and morphological changes occur during the so-called generative development and during the vegetative processes in seeds. The most characteristic biochemical and compositional changes of this period are the formation and decline of storage components or their precursors, the change of their degree in polymerization and an extensive change in water content. The aim of the present study was to detect the maturation processes in seed nondestructively and to verify the applicability of near infrared spectroscopic methods in the measurement of physiological, chemical and biochemical changes in wheat seed. The amount and variation of different water “species” has been changed intensively during maturation. Characteristic changes of three water absorption bands (1920, 1420 and 1150 nm) during maturation were analysed. It was concluded that the free/bound transition of water molecules could be followed sensitively in different region of NIR spectra. Kinetic changes of carbohydrate reserves were characteristic during maturation. An intensive formation and decline of carbohydrate reserves were observed during early stage of maturation (0 -13 days, high energy demand). An accelerated formation of storage carbohydrates (starch) was detected in the second phase of maturation. Five characteristic absorption bands were analysed which were sensitive indicators the changes of carbohydrates occurred during maturation. Precursors of protein synthesis and the synthesis of reserve proteins and their kinetic changes during maturation were followed from NIR spectra qualitative and qualitatively. Dynamic formation of amino acids and the changes of N forms were detected by spectroscopic, chromatographic and by capillary electrophoresis methods. Calibration equations were developed and validated in order to measure the optimal maturation time protein and moisture content of developing wheat seeds. The spectroscopic methods are offering chance and measurement potential in order to detect fine details of physiological processes. The spectra have many hidden details, which can help to understand the biochemical background of processes.
