The purposes of this study were (1) to investigate the important selection attributes of coffee brands and the relative positions of major coffee brands on the positioning map through similarities and preferences of coffee brands that customers perceive and (2) to provide Korean coffee brands with strategic information about how to differentiate themselves from existing competitors in the Chinese market. A total of 268 samples were used for data analysis that comprised frequency analysis, descriptive statistics, ALSCAL, and regression analysis. The results showed that among 8 coffee brand selection attributes the most important was atmosphere, followed by cleanness and sanitary condition, and convenient location and transportation. Friendly service, taste of coffee, price and variety of menu were next and brand was the least important among 8 selection attributes. The results of positioning map showed that Maan Coffee was evaluated the highest iin atmosphere, cleanness and sanitary condition, and convenient location and transportation compared to other coffee brands. Marketing strategies for Korean coffee franchisers (Angel-in-us Coffee and Caffe Bene) were provided for successful repositioning in the Beijing coffee market.

The purpose of this study is to manage job stress of foodservice employees effectively by analyzing their job stressors and relationship of job satisfaction and turnover intention. It also analyzed the effects of social support and coping strategies on job stressors. The data for the study were collected through conducting a survey to the employees who work at hotel foodservice departments and buffet restaurants in Busan area. Major suggestions and significances of this study can be outlined as follows: First, it was found that 6 job related stressors(work environment, personal relation, role, task characteristics, career development, individual character). Second, it was revealed that personal relation and career development factors have an effect on employees' job satisfaction and turnover intention. Third, it was illustrated that social support and coping strategies have a moderating effect of job stressors between job satisfaction and turnover intention.

This study was conducted to investigate the antioxidant activity and the bioactive compounds found in 70% ethanol extracts taken from Sanguisorbae officinalis L. leaves(SO) cultivated in Korea. The extracts were tested for their total phenolic contents (TPC), total flavonoid contents (TFC), phenolic compounds, and antioxidative activities using various in vitro assay such as DPPH, ABTS radical scavenging activity, FRAP activity, and reducing power. The TPC and TFC were found to be $119.3{\pm}1.54mg$ gallic acid and $59.6{\pm}1.43mg$ rutin at mg of 70% ethanol extracts, respectively. Catechin was the major material among the phenolic compounds in SO extracts. The DPPH radical scavenging activity, ABTS radical scavenging activity, FRAP activity, and reducing power of SO extracts were increased in a dose-dependent manner. These results suggest that SO extracts could be considered as a good source of natural antioxidants and functional food ingredient.

This paper investigated the effects of hotel chefs' personality and leader-member exchange(LMX) on innovative behavior. The sample for the study is 300 chefs extracted from four five-star hotels in Busan metropolitan area. Self-administrated questionnaires are distributed and 267 usable ones are collected and used for the analyses. The findings of the research are as follows, First, hotel chefs' personality consists of neuroticism, openness, friendliness, conscientiousness and extroversion. Second, hotel chefs' LMX consists of attachment, loyalty, a sense of contribution and respect. Third, hotel chefs' openness, considerateness, and leadership positively affect hotel chefs' LMX and hotel chefs' introversion negatively affect hotel chefs' LMX. Fourth, hotel chef's innovative behavior is affected by hotel chef's attachment, loyalty and respect.

In this study, the antioxidant and anti-inflammatory properties of Colpomenia sinuosa extracts were identified. Antioxidant experiments included DPPH, ABTS, nitrite scavenging experiments, and FRAP, polyphenol concentration measurements, flavonoid concentration measurements. DPPH assay results showed an antioxidant function of 2.821 mg ascorbic acid/g extract. ABTS assay results showed an antioxidant function of 3.923 mg ascorbic acid/g extract. nitrite assay results showed an antioxidant function of 17.89 mg ascorbic acid/g extract. In FRAP, 1 mg of the Colpomenia sinuosa extract showed a reduction of 2.062±0.177 ㎍ of ascorbic acid. For polyphenols, 62.85±3.18 mg/g was shown. Flavonoids showed 10.01±0.24 mg/g. In the meantime, cell experiments showed cytotoxicity and anti-inflammatory functions. In cytotoxicity experiments, Colpomenia sinuosa extracts showed cytotoxicity of less than 20% and an inflammatory inhibition of 30.93±2.93% at a concentration of 100 ㎍/mL. These results indicate that Colpomenia sinuosa extract is available as functional cosmetic material.

The antioxidant activity of Chrysanthemum indicum L. extract (CIL) was investigated by fermenting lactic acid bacteria with the CIL from 64% and 80% ethanol extraction and measuring the total phenolic contents (TPC), flavonoid, 2,2-diphenyl-1-picrylhydrazyl (DPPH), reducing power (RP), and linoleic acid auto-oxidation inhibitory activity. CIL was confirmed to inhibit bacterial auto-oxidation. TPC was increased in strains 3109 and 3237, while flavonoid decreased in all strains. DPPH was increased in strains 3074 and 3109 fermented with 64% CIL and all the strains with 80% CIL. RP was increased and linoleic acid auto-oxidation inhibitory activity decreased in all the strains fermented with 64% or 80% CIL. Among the 4 strains, strain 3109 had the highest DPPH and RP; thus, it was most effective in increasing CIL's antioxidant efficacy through the fermentation process.

We investigated the quality characteristics and volatile flavor components in yenipsambab prepared with various concentrations of lotus leaf powder. Hunter's color L and a values of yenipsambab decreased with increasing content of lotus leaf powder, whereas b value increased. Moreover, addition of lotus leaf powder resulted in increased hardness, adhesiveness, chewiness, and brittleness compared to control. Major volatile compounds of yenipsambab were ethyl benzene, 1,3-dimethylbenzene, 1,2-dimethylbenzene, and 5-hydroxymethyldihydrofuran-2-one.

The purpose of this study is to find out not only customer demands and satisfaction with service quality in restaurants, but the difference between customer satisfaction and employee practice. This study also identifies the factors affecting customer satisfaction. For the purpose, 116 copies of a questionnaire for employees and 213 for customers were analyzed with frequency, percentile, mean, multiple regression analysis, T-test, one-way ANOVA, and Duncan's Multiple range test, using SPSS/WIN 10.0 program. The major findings obtained in this study are as follows: First, customer demands were affected mostly by educational level among socio-demographic variables. Second, customer demand for service quality was not fully being met, considering customer satisfaction level. Third, employee practice was generally above customer satisfaction. Fourth, One of the variables that chiefly affect customer satisfaction was demand for information and facilities.

Development of chocolate products to improve the quality and sensory properties with Saengmaeg-san powder (SP) was attempted. Effects of SP on color, viscosity, total phenol compound content, radical scavening activity and sensory characteristics. In color, lightness value was increased than milk chocolate without SP Also viscosity was significantly higher than chocolate without SP.Total polyphenol content of Saengmaeg-san chocolate was 191.52 mg/1 OOg and Dpph scavenging activity was 87.06%. Results of sensory evaluation, significant different (p < 0.05) were shown in softness, sweet taste, sour taste, bitter taste, texture and overall acceptability depending on the addition of SP.

This study was conducted to investigate change of rate of laying eggs and vitamin according to feeding of far infrared-irradiated rice. The feeding of rice irradiated by far infrared rays did not affect the body weight of laying hens, but the rate of laying eggs were 14% positively increased than normal rice. Especially, the levels of vitamin A(150${\sim}$200%), D(28${\sim}$30%) and E(40${\sim}$67%) were much higher in the group of laying hens fed with rice irradiated by far infrared rays.
