This study examined the relationship between chlorophyll(Chl) and ascorbic acid(ASA) as an index of freshness for vegetables, when the general consumers purchase several kinds of vegetables at the market. The leaves and fruits of several types of vegetables were divided into top, middle, and basal sections. Chl was determined by a spectrophotometer, and ASA was analyzed by high-performance liquid chromatography. For the vegetable sections, we found that Chl and ASA levels were highest in the top sections, followed by the middle, and were lowest in the basal portions. For the relationship between Chl and ASA in vegetables, there were seven classifications including high Chl(above 80mg/100g of fresh weight) and high ASA(above 80 mg/100 g of fresh weight) for mallow, and kail; the second group had high Chl and low ASA(below 80 mg), such as in spinach, burdock, and perilla leaves; the third group contained medium Chl($40{\sim}80mg$) and medium ASA($40{\sim}80mg$) levels, such as for gonddalbee, angelica, pumpkin leaf and coriander; the fourth group had medium Chl and low ASA levels, as in crown daisy and lettuce; the fifth group contained low Chl(below 40 mg) and high ASA, such as in hot peppers and parsley; the sixth group had low Chl and medium ASA levels, and included broccoli, pak choi, and sweet peppers; finally the seventh group contained low Chl and low ASA levels, as in dropwort, young radishes, shallots, cucumbers and swiss chard.

New application of rice was carried out by coating the rice with the mixture solution of ginseng and chungkukjang water extract The physicochemical characteristics of the coated rice were investigated. Moisture content of uncoated (15.26%) and coated rice$(15.57\sim15.66%)$ was not different significantly. The contents of crude protein, crude fat, and crude ash of the coated rice were higher as much as $4.28\sim11.82%\;8.47\sim47.46%$, and $11.54\sim42.31%$ than those of control, respectively. As total free amino acids in coated rice were increased by augmenting the amount of the extract, total free amino acids according to rate was increased to $3.1\sim7.8$ times. The major amino acids in the coated rice was alanine$(19.56\sim39.88\;mg%)$, leucine$(5.14\sim17.66\;mg%)$, and proline$(9.98\sim16.82\;mg%)$. Of those amino acids, alanine and $\gamma-aminobutyric$ acid in only coated rice were detected to the level of $19.56\sim39.88\;mg%$ and $7.78\sim12.36\;mg%$ respectively. The calcium amount of coated rice was increased to 15% to 20%. As increasing the coating rate, hardness, cohesiveness, chewiness, and brittleness of coated rice were decreased, but springiness was increased. Before cooking, the color of coated rice appeared yellow and after cooking turned to the light yellow. The color intensity was increased feasibly as increasing the coating rate. The sensory characteristic of rice coated manufactured by adding 15% of the extract was best and found to be similar to that of the control.

As for the difference in the perceived service value: longer the period of SNS use, more preferred was the blog: the more number of visiting times, the higher perceived service value. As for the difference in the online mouth-to-mouth intention: longer the period of SNS use, longer was access time: the more number of visiting times, the higher online mouth-to-mouth intention. Therefore, these research results provide useful implications in the working-level aspects such as providing basic data and the academic approach of the study, when the food service corporations establish marketing strategies through SNS.

Recent amendment on the Food Sanitation Act in Korea mandated the Minister of Food & Drug Safety to secure the scientific basis for management and reevaluation of standards and specifications of foods. Especially because the current food safety control is limited within the scope of 'Farm to Market' covering from production to retail in Korea, safety control at the plane of true 'Farm to Fork' scope is urgently needed and should include 'total diet' of population instead of individual food items. Therefore, 'Total Diet Study (TDS)' which provides 'closer-to-real' estimates of exposure to hazardous materials through analysis on table-ready (cooked) samples of foods would be the solution to more comprehensive food safety management, as suggested by World Health Organization and Food and Agriculture Organization of the United Nations. Although the protection of diets from hazards must be considered as one of the most essential public health functions of any country, we may need to revisit the value of foods which has been too much underrated by the meaningless amount of some hazardous materials in Korea. Considering the primary value of foods lies on sustaining life, growth, development, and health promotion of human being, food safety control should be handled not only by the presence or absence of hazardous materials but also by maximizing the value of foods via balancing with the preservation of beneficial components in foods embracing total diet. In this regard, this article aims to provide an overview on TDS by describing procedures involved except chemical analysis which is beyond our scope. Also, details on the ongoing TDS in Korea are provided as an example. Although TDS itself might not be of keen interest for most readers, it is the main user of the safety reference values resulted from toxicological research in the public health perspective.

To determine the sodium content of meals provided by foodservice institution, 540 different menus were collected by their serving portion and categorized into nine food groups and three different foodservice types (office, industry, school). Each were evaluated by each sodium evaluation method. All nine categories of food type showed higher content of sodium than listed in the 'nutrition assessment program (Can-Pro 4.0)', when assessed with a salimeter. From the 9 food types, 6 types, excluding 'Korean pancakes', 'Kimchi/pickled food' and 'a la carte', showed significantly higher sodium content on the salimeter than shown in the 'nutrition assessment program (Can-Pro 4.0)' (p<0.001). Also in assessing sodium content per serving, 'soup and stews' and 'a la carte' menus had significantly higher sodium content than other food types (p<0.001). The results compared by foodservice types showed dishes served in 'Industries' had significantly higher daily sodium content than those served in 'offices' and 'schools'.

This study was conducted to identify the relationship among various service quality clues, brand trust, brand distinctiveness and revisit intention focusing on fast-food restaurant consumers. Using online questionnaires tool in South Korea, a total of 450 questionnaires were distributed and 390 participants were used for further statistical analysis through SPSS 21.0 and AMOS 21.0 for Windows. Four service quality factors (menu, interior, exterior, staff) were extracted from twelve questions. According to the result of this study, several service quality factors of fast-food restaurants' have positive effects on brand trust and distinctiveness. Specifically, staff and menu and exterior were significant predictors of brand trust, and staff and menu of fast-food were critical antecedents of brand distinctiveness. In addition, the brand trust has positive influence on brand distinctiveness as well as revisit intention. Although there are many studies which proved the relationships among various selection attributes and other outcome variables such as brand loyalty or image, little research explained the relationships among service quality factors of fast-food restaurants, brand trust, brand distinctiveness, and revisit intention. Therefore, present study will contribute to provide significant results and some practical implications in both the fast-food restaurant industry and academic research.
