The present study aimed at assessing the protective effect of water extract from fruit body of the Grifola frondosa (GFW) on carbon tetrachloride ($CCl_4$)-induced hepatotoxicity. Rats orally administered with GFW 0.5, 1.0, 2.0 g/kg for 14 days were treated with $CCl_4$ to induce hepatotoxicity. Pretreatment with GFW remarkably prevented the elevation of serum AST, ALT, ALP, LDH, $\gamma$-GTP, and liver lipid peroxides in $CCl_4$-treated rat and GFW administration in liver injured rats by $CCl_4$ showed significant (p<0.05) protection of liver as evidenced from normal serum enzymes and malondialdehyde (MDA) levels. In the ultrastructural changes, administration of $CCl_4$-induced damage of hepatocytes with vacuolation, a highly damaged endoplasmic reticulum, and degenerating nuclei. However, pre-administration with GFW preserved normal ultrastructure of hepatocytes. These results suggest that GFW had an effect to inhibit $CCl_4$-induced liver injury in rat, and that it could be used as an effective hepatoprotective agent against chemical-induced liver damage.

This study was conducted to evaluate the menu of a Japanese restaurant in a first class tourism hotel. The calculations used for the menu analysis were conducted using MS Excel 2003. Several previous studies have been conducted to analyze menus. For example, Pavesic used of the weighted contribution margins (WCM) and potential food cost (PFC%) to evaluate menus, while Kasavana & Smith used the mix margin (MM%) and unit contribution margin (CM) to evaluate menus. The menu engineering method focused on the customer's viewpoints, while the Cost/Margin analysis method considered the manager's viewpoints. The menus that need continuous keeping Kasavana & Smith (Star) and Pavesic (Standard) included 'Assorted sashimi with side dishes (big), 'Lunch box special', 'Tempura course', 'Broiled Spanish mackerel and side dishes', 'Shrimp tempura', 'Special sushi', 'Seafood Udong', 'Buckwheat noodles'. The results of this study should increase customer satisfaction and profits at the Japanese Restaurant.

The purposes of this study were to (1) identify foreigners’ evaluation of service performance, (2) define foreigners’ needs for each segment of Korean traditional restaurants, and (3) plan the adaptation strategies for Korean traditional restaurants on foreign countries. From April to July, 2005, 542 foreigners responded to an individual survey. Statistical analyses on SPSS 12.0 for Windows were performed on the survey data using descriptive statistics, factor analysis, reliability analysis, independent-samples t-test and ANOVA. The major findings from the study are as follows. First, among all the attributes, ‘Offer free additional side dishes’ scored the highest, followed by ‘taste of food is good’ and ‘temperature of food is proper’. Second, factor analysis classified the service attributes into four factors in the following order of importance: menu, sanitation, service, and facility and atmosphere. Finally, foreigner groups categorized by their general characteristics, including demographics, showed statistically differences in their evaluation. In consequence, the research findings suggest that operators of Korean traditional restaurants should understand different customers’ needs within and between customer segments.

본 연구는 레스토랑 산업에 널리 적용할 수 있는 외식 서비스 품질 측정을 위한 다문항 척도를 개발하였다. 척도 개발을 위해 Kelly Repertory Grid 방법을 이용하여 중요하게 생각하는 레스토랑 품질 속성을 파악한 후 전문가 토론을 수차례 거쳐 유사 중복 항목을 통합하고, 핵심 차원별 주요 속성을 도출하였다. 척도 정제를 위해 신뢰도 분석과 탐색적 요인 분석을 실시하였으며, 이후 각 구성 개념에 대한 중복성 여부를 확인하기 위하여 3차 확인 요인 분석을 실시하였다. 본 연구에서는 Brady & Cronin(2001)이 제안한 위계적 서비스 품질 모형을 바탕으로 외식 서비스 품질 척도를 개발하였다. 본 연구의 위계적 외식 서비스 품질 모형은 외식 서비스 품질 차원 및 측정 요인을 물리적 환경 품질, 상호 작용 품질, 음식 품질이라는 핵심 차원으로 설명함으로써 요인간의 중복성 완화, 결과와 과정 품질의 균형적 고려, 세 가지 핵심 차원별 관리포인트 명확화, 위계적 모형에 의한 핵심 차원과 하위 차원의 구분 등 이론적 기여 측면에서 뿐만 아니라 관리적 시사점 도출 측면에서도 우위성을 갖는다고 할 수 있다.
