The aim of this study was to investigate the characteristics and antioxidant activities of vinegar made with Etteum bell flower root (0.5%, 1%, 1.5% and 2%) during two-step fermentation. Acetic acid was fermented at $30^{\circ}C$ for 16 days and samples of vinegar were extracted at 2, 4, 6, 8, 10, 12 and 16 days. The pH of Etteum bell flower root vinegar did not significantly differ among the samples, but the acidity increased during fermentation. Alcohol content decreased at 16 days of fermentation and less than 1% alcohol was shown in all samples after fermentation. The pure acetic acid yield was 88.85~98.97%, whereby the total phenolic compound content and 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging activities increased as the ratio of the Etteum bell flower root increased. The sensory scores of vinegar fermented with 1.5% Etteum bell flower root are greater than those of vinegar prepared by other treatments. Therefore, vinegar with 1.5% Etteum bell flower root added is considered to be the most suitable for manufacturing.

The purpose of this study was to find appropriate processing condition of astringent persimmon and persimmon leaf granular tea. Under the condition of 4 hour extraction and $50^{\circ}brix$, extraction yield and concentrating of astringent persimmon were the greatest. Under the condition of 2 hour extraction and $7^{\circ}brix$, extraction yield and concentrating of persimmon leaf were the greatest. The optimum condition of granular tea with astringent persimmon and persimmon leaf added was the best in astringent persimmon concentrate of 16% and persimmon leaf concentrate of 4%. It had the best taste after the condition in a brix value of 16.15% and a pH of 5.57. The L-value of chromaticity was -79.13, a-value 2.27, and b-value 2.41. In the sensory properties correlation analysis of astringent persimmon and persimmon leaf granular tea, sweet taste, color acceptability, odor acceptability and taste accept-ability were positively significant correlation with most sensory properties. However, astringent taste was no significant correlation with sensory acceptability. Bitter taste and after taste were negatively significant correlation with most sensory properties.

In this paper, we surveyed the actual utilization condition of chain stores of franchise systems and the customers' consciousness on chain shops and non-chain restaurants. The survey was conducted on 459 people either living or working in Pusan area and aged more than 4th grade in elementary school without sex distinction. The data analyses were made by way of frequency, percentage, Spearman rank correlation and Chi-square using dBastat 1.0 package of PC. The results of the survey are as follows. The survey indicates that respondents have the most experience of visiting chicken, hamburger, and pizza chain shops. Although the survey on the degree of preference between chain shops and non-chain restaurants indicates that men prefer non-chain restaurants and women prefer chain shops, the results are not so significant to conclude that there is a preference regardless of sex (N. S.): By ages, students and young group prefer chain shops and the aged group prefer non-chain restaurants (p< 0.05). The survey indicates that chain shops are proffered because of sanitary, quality, taste of foods and are not proffered because of simple menu and expensiveness. The survey indicates that non-chain restaurants are preferred because of distinctive taste of each restaurant and comfotableness, and are not proffered because of unsanitary and unkindness.

This study is written to look into microbiological quality by passage of time and holding methods after making foods, by means of evaluating time, temperature and microbiological quality during various phases in product flow of cold soybean noodles serviced by an industry feeding operation for 500 persons a day, measuring pH & Aw and analyzing factors affecting microbiological growth conditions. The results were as follows: 1. According to phases in product flow of cold soybean noodles, it showed 15.6 hours of mean of needed time, $24.2^{\circ}C$ of room temperature, 5.1~7.6 of pH value & 0.95~0.98 of Aw except dry noodles. These conditions were good for multipling of microbe, and the phases with potential sanitary danger were ingredient, pre-preparation, holding before assembly and service and assembly & service. 2. As for holding methods and passage of time, holding at cold table was more effective than holding at room temperature as time past. 3. As for equipments using for making food, dipper, basket, kitchen board & kitchen towel showed high microbiological value in total aerobic plate counts and kitchen towel and stainless-steel were showed high microbioloical value in coliform counts. 4.

Design/methodology/approach - This study collected 286 survey data from customers who had experience buying and drinking the protein beverage. The Exploratory Factor Analysis (EFA) and the multiple regression analysis were hired in order to analyze the data. Findings - First, four dimensions of health lifestyle("health confidence," "health sensitivity," "health intention," and "health eating habit") were found to be valid and reliable. Second, all four dimensions of health lifestyle had a positive effect on customer satisfaction. Third, customer satisfaction had a positive effect on repurchase intention. Lastly, customer satisfaction had a positive effect on recommendation intention. Research implications or Originality - This study provided research model among health lifestyle, customer satisfaction, repurchase intention and recommendation. Furthermore, the results of this study were useful for identifying the role of health lifestyle in estimating customer satisfaction and the strategies for strengthening customer satisfaction in the protein beverage market.

As oil palm trees are an important economic source in many countries, particularly in Southeast Asia and Africa, the study of Ganoderma boninense is crucial for the sustainability of the oil palm industry. This study aims to understand the biology and ecology of the fungus, its pathogenesis, and the impact it has on oil palm trees. This knowledge can be used to develop management strategies to mitigate the damage caused by the fungus, such as the use of resistant varieties, chemical and biological control methods, and cultural practices. This study is to ensure the long-term productivity and sustainability of the oil palm industry. The main method of recent academic studies on this pathogen is molecular biology, with a focus on genetic analysis and functional genomics. Researchers have used techniques such as PCR, DNA sequencing, and transcriptomics to identify genes and pathways involved in pathogenesis and better understand the fungus's interactions with its host plant. Other methods used in recent studies include biochemical analysis, microscopy, and phytohormonal assays to investigate the biochemistry and physiology of the interaction between G. boninense and oil palm. This study is intended to provide implications from a new perspective by organizing and integrating studies on Ganoderma boninense.

Food waste is inevitable in any institutional food system. Although many factors contribute to plate waste, few quantitative studies of plate waste have actually been carried out. This study was undertaken to check (a) how the service style that affects the amount of plate waste, (b) the difference of plate waste between men and women and, (c) the influence of plate waste and customers'satisfaction to served meal. The survey was conducted through March 15 and April 9, 2000 by weighing the amount of plate waste and by questionnaires. Statistical data analysis was completed using the SPSS-PC program for descriptive analysis and ANOVA test. The results were as follows; (1) The largest amount, plate waste percentage measured were 19% of‘Hot alaska pollack soup’and 18% of‘Kuansh soup’respectively. (2) Amount of leftovers can be reduced if the pre-portioned serving style is changed to self-portioned serving. (3) The main reasons for leaving leftover were‘served too often’and‘disliked food’. (4) The customers'satisfaction rate was highly correlated with the leftover amounts.

본 연구의 목적은 외식산업 주방에서 안전 매뉴얼의 방향을 제시하고자 하였다. 외식산업 주방에서의 사고는 87.2%의 매우 높은 사고경험을 가지고 있다. 사고의 유형별로는 칼로 인한 베임(84.7%)이 가장 많았으며 그 뒤를 이어 뜨거운 불과 물, 기름 등에 의한 화상인 데임(74.4%)과 넘어짐(28.1%) 순으로 나타났다. 성별에 대한 주방안전환경에 대한 인식과 개인의 주방안전 이행 정도에서는 남녀간 유의적 차이를 보임으로써 남성이 여성보다 사고 확률이 높다고 볼 수 있다. 근무연수에서 보여주는 주방안전과 안전이행정도는 1~3년차일 때 가장 높게 나타나지만, 7~10년이 되면 가장 낮은 것으로 보여지는 것은 환경에 익숙해지면서 위험도에 둔감해지는 시기로 볼 수 있어, 년수가 지날수록 위험에 대한 환기를 시켜 안전수칙 이행도를 높일 수 있어야 할 것이다. 순환적 구조에서 예방과 사고처리, 사후처리과정을 보다 전문적인 관점에서 심도 있게 검토하여 외식주방의 안전을 지키는 매뉴얼로 제시하는 바이며, 이를 기본으로 하여 각 외식주방별 환경에 적합하도록 수정 보완하여, 향후 사고 예방과 대처에 필요한 매뉴얼을 개발, 배치할 수 있는 방안을 향후 과제로 제언하는 바이다.
