  • Korean foods sold restrant and hotel accompaines so many kinds of side dishes. The menues never considered on the nutritional standpoint nor the volume that can be eaten by customers. The purpose of this study is to simplify and improve the menu of Korean foods sold in restrant. To find out the problem and the method of the betterment Korean food sold in restrant. The survey study was made for 100 restrants in Seoul city. Ther average number of side dish of the restrant food was 23. The average amount number of the side dish was 31 and smallest number was 4. The average amount of food served was 979 grams and the average number of food taken by people was 698 grams. The average percentage of intake of food was 62%. Protein Content of the foods sold restrant was from 54% to 240% over the recommended dietary allowances. Protein intake also exceeded from 19% to 147% of recommended dietary allowances. Age of the customers were surveyed to set up the standard amount of the nutrients. About 68% of the customers were from 30 to 40 years of age in the day time (lunch), whereas about 72% were from 20 to 30 years of age in the evening (supper). From the results of the survey study, two nutritional standard were decided to be used. One is the recommended dietary allowences of 25 years of man (reference man), and the other is that of 45 years of man. The actual standards are as follows : Standard 1 (25 years of man) Calories-900~1000Cal Protein-25-30g Vegetables-200~250g (include yellow, green vegetable), Amount of food-about 800g Standard 2 (45 years of man) Calories-700~800Cal Protein-25~30g Vegetables-150~200g (include yellow, green vegetable) Amount of food-700g The kinds of food recommended to be sold in the restrant are as follows : 1. Pansang-is a formal method of korean table setting 3 types, 7 chup, 5 chup, and 3 chup were studied and made, 2. Table for the quest with drink-2 types of table setting, 9 kinds of food and 7 kinds of foods were studied. 3. free meal-in this table, one pig protein dish with kimchi, one vegetable, and one salty flsh will be served, 19 kinds of foods were studies. 4.

  • Aspirating or swallowing foreign bodies is a common occurrence. If they are wholly or partly radiopaque, their localization in and progress through the gastrointestinal tract can be more effective. Of the dental origin foreign materials swallowed, the most common things are fragments of anterior maxillary partial denture. But the radiopacity of denture base resins is not sufficient to determine the location of the objects. The purpose of this study was to develop a radiopaque dental acrylic resin, which has clinically detectible radiopacity with minimal change of mechanical properties and color. The radiopacity, color change(CIE 6..E) and microhardness of acrylic resins were determined after mixing barium sulfate or iodide compound. Thermocycling course was conducted to determine the change of characteristic of resins after using for a long time in the mouth. Five or ten percent of barium sulfate to total weight of cured material was mixed with heat curing dental acrylic resin or chemically curing orthodontic resin. In the case of iodide compound, the mixing ratio was two or three percent. After mixing the high radiopaque materials, resin was cured to 20×20×2 mm plate, polished with #600 sand paper and finally polished with Microcloth(Buehler). The specimens were thermocycled in 5 and 55 t distilled water for 2,000 times, and the measurement of radiopacity, color and Vickers hardness was repeated every 500 times thcrmocycling. The radiopacity of specimens on the X -ray films was measured with densitometer(X-rite). The color change was detennined with differential colorimeter(Model TC-6FX, Tokyo Denshoku), and the Vickers hardness number was measured with microhardness tester(Mitsuzawa). The following results were obtained : 1. All the three variables, the kinds of acrylic resins, the mixing or the kinds of high radiopaque materials and thermocycling, had combined effect on the radiopacity of the dental acrylic resins(p<0.0l). 2. The two variables, the mixing or the kinds of high radiopaque materials and thermocycling, influenced on the radiopacity of the dental acrylic resins(p<0.01). But the kinds of acrylic resins did not influence on the color change of mixed dental acrylic resins(p>0.05). 3. Each of the three variables, the kinds of acrylic resins, the mixing or the kinds of high radiopaque materials and thermocycling, influenced on the radiopacity of dental acrylic resins(p<0.0l). 4. The high radiopaque materials used in this study did not yield clinically usable radiopacity, and the color change was great after mixing those materials.

  • The study was carried out to evaluate the anticancer effects in Korean soybean paste(doenjang) added with sun-dried salt(S-D), roasted salt(R-D), bamboo salt roasted once(B1-D) or bamboo salt roasted nine times(B9-D). In MTT assay, S-D, R-D, B1-D and B9-D exhibited a significant inhibitory activity(64-87% and 68-92%) against the proliferation of AGS human gastric adenocarcinoma cells by adding 0.05% and 0.1% of methanol extract. Among Balb/c mice injected with sarcoma-180 cells, the bodies, livers, spleens, kidneys and heart weight of the mice administered with 4 kinds of doenjang extracts were heavier than the non-administered ones of the group. However, no difference was found between the control and doenjang administered groups. Four kinds of doenjang inhibited significantly the tumor growth, especially R-D and B1-D showing an inhibition of tumor cell growth up to 97% by the administration of 1.0 mg/kg methanol extracts of doenjang. The activity of natural killer(NK) cells was relatively high in mice administered with four kinds of doenjang. Particularly, mice administered with R-D methanol extract showed a stronger activity of 88.2%. The activity of glutathione S-transferase(GST) in mice administered with four kinds of doenjang was higher than that of the non-administered group. In particular, the GST activity was the strongest in the group with B1-D. As these results indicate the various kinds of salt have different effects on the anticancer activity of doenjang.

  • Finespotted flounder, used for a representative raw fish in spring, is considered comparatively difficult to breed, which causes small Olive flounder and Stone flounder from China, similar kinds of flounders, to appear on the market for sale under the name of 'Finespotted flounder.' The reason lies under the considerations that small Olive flounder and Stone flounder from China are relatively lower priced and in higher supply and demand, being difficult to distinguish from Finespotted flounder when sliced with bones. Thus, the purpose of our thesis is to distinguish Finespotted flounder from similar kinds of fish analyzing the lipid content in slices of raw fish and SDS-PAGE(sodiumdodecylsullipide-polyacrylamide gel eletrophoresis). Upon comparing the main components between sliced Finespotted flounder and similar kinds of fish, such as small Olive flounder and Stone flounder from China, we found that there are no noticeable differences among them in moisture content, and little, if any noticeable differences, in crude protein and ash content(P>0.05). Based on these analyses, we have conclude that commercial raw fish restaurants sell small Olive flounder and Stone flounder under the name of Finespotted flounder. However, a variety of factors have an effect on our analysis, such as the individual characteristics of fish and a seasonal variation. The aim of our analysis is to enhance more accurate distinction criteria, although some fish kinds can be discerned with our present technique of examining lipid content and SDS-PAGE. Through more sophisticated analyses developed by consistent research, we look forward to attaining more accurate techniques for discerning between Finespotted flounder and different kinds of similar fish.

  • $D{\acute{o}}ck$ (Korean rice cake) is a peculiar food of Korea made of grain. By means of cooking from, it is defined as 'Pulvberzed food of grain' $D{\acute{o}}ck$ was one of the daily food, but development of boild rice had narrowed it's use to the food of festive days and ceremonies. $D{\acute{o}}ck$ is used as a main food of all Kinds of ceremonies from one's birth to death, such as the Three seven day(a baby's twenty-first day of life), one hunderdth day, birthday, wedding, both brithday, funeral and sacrifical rites, vocational ceremonies, such as a sacrifice to spirits and a srevics for a big catch of fish. It is also used as a present and seasonal food. A large variety of $D{\acute{o}}ck$ is available and its recipe is scientific and reasonable. In this treatise, the Kinds of $D{\acute{o}}ck$ and the frequency of them, the material, the recipe, the measuring unit of material, cooking kitchen utensils and the cooking terms are studied from the books published in Korea from 1670 to 1943. 1. $D{\acute{o}}ck$ was classified as Tcbin $D{\acute{o}}ck$(steamed), Chin $D{\acute{o}}ck$(strikn), Chijin $D{\acute{o}}ck$(fried) and Salmun $D{\acute{o}}ck$(boiled), according to its way of cooking. 2. There were 122 Kinds of $D{\acute{o}}ck$, 57 were Tchin $D{\acute{o}}ck$, 35 Chin $D{\acute{o}}ck$, 20 Chijin $D{\acute{o}}ck$, and 10 Salmun $D{\acute{o}}ck$. 3. There were 34 Kinds of measuring units. Of them, 13 for volume, 4 for weight, 9 for quantity, 4 for length and 4 for the rest. 4. There were 55 Kinds of cooking Kitchen utensils but now many of them are not used because of mechanization or automation of tools of living. 5. There were 143 Kinds of cooking terms. Of them 49 for the preparing process, 25 for the mixing process, 27 for well-forming process 10 for process of getting ready to cook, 14 for heating process, 10 for cutting process, 5 for dishin process and 3 for process of soaking in sugar or honey.

  • The purpose of this paper is to give convergence theorems both for closed convex set valued and relative fuzzy valued martingales, and sub- and super- martingales. These kinds of martingales, sub- and super-martingales are the extension of classical real valued martingales, sub- and super-martingales. Here we compare two kinds of convergences, in the Hausdorff metric and in the Kuratowski-Mosco sense. We also introduce a new convergence for the fuzzy valued case in the graph sense and obtain convergence theorems.
