This study was conducted to develop the standard recipe of Dopyun according to the various content of mung bean starch and sugar. The effects of mung bean starch(10%, 15%, 20%) and sugar(20%, 30%) were evaluated on textural and sensory properties of Dopyun through the mechanical properties using texture analizer and sensory evaluation. Color was tested by color and color difference meter. For sensory evaluation, higher content of sugar and lower content of mung been starch(sugar 30%, mungbean starch 10%) showed advantages in acceptance fo taste and overall quality. Mechanical properties of hardness, cohesiveness and chewiness of Dopyun were increased significantly in Dopyun with higher content of mung bean starch and sugar. The values of Hunter color system indicated that "L" and "b" values tended to decrease and "a" value increase, as the mung bean starch and sugar proportion increased. In the analysis of correlation between sensory evaluation and acceptance test, it was found that they were highly related. In view of the above results, it came to the conclusion that Dopyun with the addition of 30% sugar and 10% mung bean starch could give the best result among the groups studied.sult among the groups studied.

In order to examine the pre-industrial application product quality characteristics of yanggang (a type of traditional Korean confectionery) with varying levels of Palatinose, this study conducted multiple preliminary experiments. By applying different amounts of Palatinose (1%, 2%, 3%, 4%) and adhering to a recipe suitable for commercial products, the yanggang was produced under controlled manufacturing conditions. While the moisture content of the manufactured yanggang adhered to the established manufacturing standard, showing minimal variations, there were statistically significant differences observed with an increase in the Palatinose proportion, exhibiting a trend akin to findings from other yanggang studies. Similarly, there were slight but statistically significant differences observed in soluble solids content and pH, though these differences were not found to have a significant impact. The addition of Palatinose did not induce changes in the elasticity (springiness) and firmness (gumminess) of the yanggang, nor in its chewiness, as the Palatinose content increased. Despite a reduction in calorie content, the addition of Palatinose did not influence the appearance and taste of the yanggang.
In recent yearn, eating habit that is not right causes disease the dietary fiber (DF) intakes of Korean decreases. Occurrence of chronic disease such as constipation increased gradually. This study was performed to investigate of high fiber standard recipes for one day including major source of DF such as vegetables, cereals and grain products, seaweeds, fruits, fungi and mushrooms, and legumes and products for improving constipation through dietary treatment. Nutrient analysis per person marked energy, protein, fat and DF content. The food of high I : S ratio (Insoluble fibers: Soluble fibers) are soybean sprout salad, rice gruel with vegetables, pan fried mushroom with vegetables. The food of low I:S ratio are fermented soybean paste stew, fried rice with kimchi, fruits salad with yogurt dressing and seasoned noodle with vegetables. The representative high fiber diet menu is rice gruel with vegetable, rice with radish and oyster, fermented soybean paste stew, kimchi stew, assorted soybean sprout salad, three kinds of pancake roll, pan fried mushroom with vegetables, fruits salad with yogurt dressing and seasoned noodle with vegetables. The menu developed in this study, contains fiber of at least 8.97 times of RDA and in point view of 1 day intake, that is similar to the scope of RDA, 20-25 g per day. This findings should be appliable to nutritional education and medical food for constipation. And also, the aim of study is constipation patients easily applicate that developed the food of high fiber using Korean common food. And the result of the study will be the basic data about clinical test of food developed in this study and the danger of high fiber diet. The representative high fiber diet menu is rice gruel with vegetable, rice with radish and oyster, fermented soybean paste stew, kimchi stew, assorted soybean sprout salad, three kinds of pancake roll, pan fried mushroom with vegetables, fruits salad with yoghurt dressing and seasoned noodle with vegetables. This findings should be applicable to nutritional education and medical food for constipation.
The principal objectives of the experiments in this study were to assess the quality of venison jerky made from Elk deer (female, weight; 380 kg, age; 15 old years) in accordance with various seasoning sauce and mixture fruit extract level. Salinity, saccharinity and acidity values of the seasoning sauces were all high(VJ-1; 3.72%), (VJ-3; 3.95%), (VJ-1; 0.35%). The salinity range of the venison jerky products was 5.65~5.92%, the saccharinity range was 3.75~4.18%, and the seasoning sauce samples resulted in a significant difference in acidity values(p<0.05). Crude protein, fat and ash contents of the venison jerky products satisfied the Korean jerky standard value, but the moisture content range was 36.18~38.59%, and this was also in excess of the jerky standard level. The manufacturing yield was 42.24~44.48%, with VJ-1 at lowest levels followed by VJ-2 and VJ-3. The pH value of VJ-1 was high, but not significantly higher than the other samples(p>0.05). The water activity value range was measured at 0.68~0.71, and the lightness(L) and redness(a) value evidenced marked increases with increased amounts of added sodium nitrite(p<0.05), and the yellowness(b) values did not significantly differ(p>0.05). The overall sensory acceptance scores ranged between 5.53~7.49, in the order VJ-3, VJ-2, VJ-1(p<0.05).
The effect of setup uncertainties on CTV dose and the correlation between setup uncertainties and setup margin were evaluated by Monte Carlo based numerical simulation. Patient specific information of IMRT treatment plan for rectal cancer designed on the VARIAN Eclipse planning system was utilized for the Monte Carlo simulation program including the planned dose distribution and tumor volume information of a rectal cancer patient. The simulation program was developed for the purpose of the study on Linux environment using open source packages, GNU C++ and ROOT data analysis framework. All misalignments of patient setup were assumed to follow the central limit theorem. Thus systematic and random errors were generated according to the gaussian statistics with a given standard deviation as simulation input parameter. After the setup error simulations, the change of dose in CTV volume was analyzed with the simulation result. In order to verify the conventional margin recipe, the correlation between setup error and setup margin was compared with the margin formula developed on three dimensional conformal radiation therapy. The simulation was performed total 2,000 times for each simulation input of systematic and random errors independently. The size of standard deviation for generating patient setup errors was changed from 1 mm to 10 mm with 1 mm step. In case for the systematic error the minimum dose on CTV $D_{min}^{stat{\cdot}}$ was decreased from 100.4 to 72.50% and the mean dose $\bar{D}_{syst{\cdot}}$ was decreased from 100.45% to 97.88%. However the standard deviation of dose distribution in CTV volume was increased from 0.02% to 3.33%. The effect of random error gave the same result of a reduction of mean and minimum dose to CTV volume. It was found that the minimum dose on CTV volume $D_{min}^{rand{\cdot}}$ was reduced from 100.45% to 94.80% and the mean dose to CTV $\bar{D}_{rand{\cdot}}$ was decreased from 100.46% to 97.87%. Like systematic error, the standard deviation of CTV dose ${\Delta}D_{rand}$ was increased from 0.01% to 0.63%. After calculating a size of margin for each systematic and random error the "population ratio" was introduced and applied to verify margin recipe. It was found that the conventional margin formula satisfy margin object on IMRT treatment for rectal cancer. It is considered that the developed Monte-carlo based simulation program might be useful to study for patient setup error and dose coverage in CTV volume due to variations of margin size and setup error.

Foodservice information systems management practices were assessed in hospital foodservice operations. A total of 46 dietetic departments were responded for the study and their practices of foodservice information systems were analyzed. The respondents were questioned about general characteristics of respondents as well as hospital foodservices implementation status of information systems. Statistical data analysis was completed using the SPSS package program for descriptive analysis, factor analysis, t-test and ANOVA test. 43.2% of total respondents gained informations by benchmarking of other hospital foodservice operations, but 7.8% gained through career education. They expected the enhanced efficiency of their tasks through implementing information systems. Based on factor analysis, information systems were divided into 6 management areas such as database management, meal management, nutrition management, purchasing management, production management and foodservice management. The average implementing scores were : database management 3.77, meal management 3.26, nutrition management 3.52, purchasing management 3.26, production management 2.73 and foodservice management 3.70 (score 1 indicates very poor and score 5 is very good). Among database management areas, standard recipe database and food item specifications database build-up scores(3.91) were relatively very high, but meal assessment and foodservice management reporting scores(2.43) were very low. The results suggest that it is necessary to build up automated foodservice management reporting system for the improvement of efficiency and productivity of operational tasks.
To assess the risk of V. parahaemolyticus infection caused by consumption of raw oysters in Korea, contamination levels during the retail-to-table route of oysters was modeled to predict V. parahaemolyticus growth based on temperature and time. The consumed amount data of the KNHANES and the standard recipe of RDA were applied. A consumption scenario for exposure assessment was developed and combined with a Beta-Poisson dose-response model. The estimated probability of illness from consumption of pathogenic V. parahaemolyticus in raw oysters during three separate months (April, October, and November) was $5.71{\times}10^{-5}$ (within the 5th and 95th percentile ranges of $2.71{\times}10^{-8}$ to $1.03{\times}10^{-4}$). The results of the quantitative microbial-risk assessment indicated that the major factors affecting the probability of illness were the initial contamination level at the retailer, the consumed amount, the prevalence of pathogenic strains [tdh or trh genes], and exposure temperature and time.
The purposes of this study were: a) to develop the a quality measurement tool for the contract-managed hospital foodservice, and b) to evaluate their performance with the developed quality measurement tool, and c) to verify the reliability and validity of the quality measurement tool. The developed quality measurement tool comprised two parts, which were foodservice management and medical nutrition care service. The foodservice management part was classified into six functional categories which were Menu, Procurement and Storage, Production and Distribution, Facility and Utility, Sanitation and Safety, and Management and Evaluation. The medical nutrition care service part indicated the medical nutrition care provided. Quality measurement tool had 91 standards and 324 indicators. The quality measurement tools were distributed to the hospital foodservice manager employed by the foodservice company. The 324 indicators were measured by foodservice manager on the 5-Likert-type scales, and then adapted to a 100 point scale. The SPSS Ver. 11.0 was used for statistical analysis. The categories whose scores were evaluated as being high were Procurement', General Sanitation', Personal sanitation' and Waste' and the categories whose scores were evaluated as being low were Diet Order Manual', Standard Recipe', Appropriateness (Facility and Utility)', Check (Facility and Utility)'and Information Management'. All the categories of medical nutrition service were evaluated as having seriously low scores. Therefore, it was necessary for the contract-managed hospital foodservice to improve its performance in the area of medical nutrition care service. For the verification of the developed quality measurement tool, the reliability obtained by calculating Cronbach's α was 0.8747, and the content validity was also proved by scrutiny of the modification of the Professional group's techniques.

The purpose of this study is, to examine current foodservice management practices at free meal service organization for elderly people and, to evaluate the attitude of recipients about the service and their ecological background. 6 meal service center as well as randomly selected 120 recipients at Sungnam area were surveyed and interviewed and result were summarized as follow. The cost of each meal (lunch) was ranged from 1,300 won to 1,500 won and number of attendant at meal service were ranged from 50 to 200 persons. Meal time for lunch begins from 10:30 am to noon because greater portion of people (elderly) didn't take breakfast frequently. Most of the center adapted self-service system. Standard recipe was not developed and meal preparation was controlled under the experiences of volunteer’s. Recording system of, nutrition management, production control, storage and inventory control was not well adapted by most of the center. In order to measure the level of storage, sanitation etc., scorin system in survey was adapted in this study and result are as follow: The score of sanitation of kitchen was lower than dinning area and that of food storage was lowest score. It was suggested that not only financial but also systematical support on management by local government may be necessary to meet the goal of supply nutritionally balanced food at the center. The score given by the recipient on the satisfaction of meal service was rate as 4.8 at the 5-point maximum scale. Meeting friends and share social relationship was major reason (41.6% of the total) of visiting to the center. It is suggested that in order to meet the changes of the patterns of change of social and family structure, the service of the center should be extended in urban area and it is necessary to develop systematic management models for the center.
