This study examines the actual conditions of toddler playwear preference survey for design and function. The study develops proper indoor and outdoor playwear for toddlers based on the analysis. A survey of 200 parents with toddlers between 2 and 6 years old and 120 teachers was conducted to find the conditions and needs for playwear along with the necessary design elements. Second, 6 designs including 3 designs for indoor playwear and 3 designs for outdoor playwear were made. These designs emphasized on soil contamination part, color, pattern, form, material, detail, and fasteners. Art play and cooking play are considered for indoor playwear and ways to decrease contamination on sleeve hem, elbow, chest, and knee were determined through the use of yellow, green, and blue colors. Applying a character and separate top with sleeves were determined. Light with breathable and waterproof fabric was determined. The correct amount of Velcro fasteners or buttons was determined for front fastening in addition a pocket was considered necessary as a detail part. The common design for both boys and girls along with a proper design for diverse play were determined. For outdoor playwear, water play, sand play, movement play, and ecology experience are considered and ways to decease contamination on hip, sleeve hem, and knee should be applied to the design as determined through the use of yellow, green, blue, and red colors. The demands for pattern, form, material, and details were similar to indoor playwear. Zipper and buttons for front fastening were determined. These final 6 playwear designs are presented using CAD WALK DESIGNWARE.

UV-catalytic oxidation technique was applied for the treatment of bio-refractory character of the leachate, which is generally present in the form of adsorbable organic halogens (AOX). Destruction of AOX was likely to be governed by pH adjustment, quantitative measurement of oxidants, and the selection of oxidation model type. Peroxide induced degradation ($UV/H_2O_2$) facilitated the chemical oxidation of organic halides in acidic medium, however, the system showed least AOX removal efficiency than the other two systems. Increased dosage of hydrogen peroxide (from 0.5 time to 1.0 time concentration) even did not contribute to a significant increase in the removal rate of AOX. In ozone induced degradation system ($UV/O_3$), alkaline medium (pH 10) favored the removal of AOX and the removal rate was found 11% higher than the rate at pH 3. Since efficiency of the $UV/O_3$ increases with the increase of pH, therefore, more OH-radicals were available for the destruction of organic halides. UV-light with the combination of both ozone and hydrogen peroxide ($UV/H_2O_2$ 0.5 time/$O_3$ 25 mg/min) showed the highest removal rate of AOX and the removal efficiency was found 26% higher than the removal efficiency of $UV/O_3$. The system $UV/H2O_2/O_3$ got the economic preference over the other two systems since lower dose of hydrogen peroxide and relatively shorter reaction time were found enough to get the highest AOX removal rate.

MMORPG는 퀘스트를 통해 진행되며 그것을 통해 레벨과 밸런스가 구현된다. 또한 퀘스트는 이야기 전달의 역할보다는 아이템과 경험치와 같은 아바타와 관련된 보상을 통한 동기부여 역할이 강하다. 이러한 상황은 결국 MMORPG를 캐릭터 성장을 위해 퀘스트의 보상을 공부해야 하는 어려운 게임으로 만들어 유저 층의 고착화를 초래하고 있다. 이러한 유저 고착화 해소방안으로 퀘스트 플레이의 동기부여 구조를 밝히고 플레이어에 대한 다원주의(多元主義, pluralism)적인 이해를 통해 다양한 유저의 플레이 동기를 증강 시킬 수 있는 퀘스트의 가능성을 살펴보았다. 플레이어의 다원주의적인 이해 방법은 다양한 유저 층의 선호도를 만족시켜줄 퀘스트를 디자인하고 평가할 수 있는 툴로써 가치가 있을 것이다.

The need for natural cosmetic ingredients has been increasing over the world nowadays. Agarose, a natural polymer from red seaweeds, has high hydrophilic character and a function of scaffolder. As skin moisturizer, agarose is adequate for percutaneous absorption. While, blueberry fruits extract possesses rich procyanidins and anthocyanins which show health benefits, anti-oxidant effect, anti-aging and anti-melanogenesis. Stability, sensory preference, skin trouble of the emulsion formula are important for cosmetic product development. In this study, we manufactured an emulsion formula for skin moisturizers using the two ingredients and tested emulsion stability and skin trouble. Total phenolic contents of the blueberry fruits extract were evaluated as well as tyrosinase inhibitory and collagenase inhibitory activities. $IC_{50}$ values of blueberry fruits extract for anti-tyrosinase and anti-collagenase activities were 168 and $112{\mu}g/mL$, respectively using gallic acid as a control ($64.8{\mu}g/mL$). The stability (pH and viscosity) of the formula containing 2% blueberry fruits extracts and 0.1% agarose was measured at five different temperatures (room temp., $25^{\circ}C$, $55^{\circ}C$, $45^{\circ}C$, $55^{\circ}C$) under the sun light at 2 day intervals for 12 days. There has been little pH change at the different temperatures. According to the sensory evaluation, there was no significant flavor, discoloration and physical changes of the formula at $25-65^{\circ}C$. These results suggest that emulsion formula containing blueberry extract and agarose could be used as a candidate for lotion and essence products.

Based on the result of extraction of common factors executed in order to elucidate the visual attributes of street scenery by types through the rotation of 23 adjective variables by Varimax, the visual attributes expressed after the construction of the facilities using street scenery were anylized to be 4 factors including factor 1 through factor 4. Theexplanation of the 4 factor groups to explain the entire distribution was 65.3% and these factor groups are the psychological attributes felt when using facilities are constructed by securing the street spaces in downtowns and the factors were named as naturalness(factor 1), locality(factor 2), identity(factor 3) and clarity(factor 4) respectively. Based on the result of one-way layout distribution analysis, the preferences for street scenery by types were found out to show considerable differences at 1 % significance level. Based on the result of multiple regression analysis, all of the factors explaining preferences including factor 1 through factor 4 were significant at 1 % significance level. In case other conditions are constant, if the values of the adjective variables related to locality(factor 2) increase by 1 unit, the preferences which are the values of dependent variables will increase by 0.709. The variable with the largest relative contribution among the 4 factor groups was the locality(factor 2) factor group and on the contrary, it was found that the independent variable with least influences was the clarity(factor 4) factor group.

Today we are inclined to dine out more frequently according as the national income is increased and Women enter into the Social life, 'This tendency results in the universality of foodculture and the food made of fresh food stuff as well as the Pollution-free food is preferable as everyone warits to eat natural food or health food and escapes from the pollution. Moreover we have socail problems like fatress and adult disease which result from the small amount of activity or the food with high calory and high gat. under this circumstance. the most adeguate food seems to be Italian good. It stand in the spottight of food world and is most preferable for everyone today. The sphere of food and beverage has a low value-added-rate compartry to the high increasing rate of customers and profit, so, the efficient managing method for the cost of food and beverage and the operating skill in the kitchen are the principal factors leading to success or failure. Therefore, this research is to show some remedies as follows, pointing out the operating problems of an selected Italian restaurant at the top class hotel. First, most Italian restaurant at the hotel are located in the best place and investing the big capital, But they are open for only 8 hours through a day. This should be improved not to bring a enormous loss to the hotel The brealefast menus such as vegetables or fish food, pizza and pasta which modern man can easily enjoy should be developed open the restaurants for morning gours. Second, the business hours are not made continously. As a result, all the emplyees should stay in the company all day long without taking any advantage of the losed time, This will be the loss for both the company and the employees, By veloping the morning menus, employees shald be classified into morning and afternoon staffs and the opening and closing hour at 3 and 6 O'clock should be used so that minimum number of employees may operate the company. Third, the characteristic of Italian food is in the use of fresh food stuff, The proper purchase of food stuff and the simple distributing system will help Italian restaurant show its character istcc as a hzgh-grade restaurant.

The medical profession has the problem of lack of bioethics, due to the expansion of capitalism and mannerism after modernization. Therefore, the need of education of bioethics is increasing, however, the cramming system of education is insufficient for promoting personal morals. So the author studied ancient and present bioethics and searched for the cause of current bioethics absence and the method of overcoming it. Especially, studying the vocational features of oriental medical doctor as profession and the problems of education of bioethics in oriental medical college, the author searched for the directions of educations of bioethics. The conclusions are as follows. The current medical profession have ethical problems because of social moral hazard, evils of capitalism, change of doctor-patient relationship due to expansion of consumerism, limitation of autonomy due to commercialize of hospitals, decrease of knowledge monopolism of professionals, moral indifference and frailty, and a missdeed preference. The education of bioethics needs "Rest's 4 components" but the current education of bioethics in oriental medicine college lacks of time and is composed of the cramming system of education. So it needs various types of education system. Morals are subjective and discretionary personal character. Therefore, informational education is insufficient for enhancing morals and complex education for various personal attainments (various social indirect experience, philosophical speculation, mental serenity) is needed. It has to be done on the basis of educational method by experience not lecture, long term expectation, and basic understanding of bioethics.

The purpose of this study was to research buying behavior and home fashion preferences based on housing size. The target consumers were Korean women, aged 20~40s who reside in the Seoul & Kyunggido areas. We distributed questionnaires to 650 women. However, only 600 questionnaires were used for the statistical analysis. Data analyses were conducted with SPSS program on the frequency, Chi-square test, cluster analysis, t-test and ANOVA. The results of this study are as follows: 1. The considering factors for purchasing such as brand, trends coordinating existing furnishings with new products and functionality were significantly associated with housing size. The buyers who reside in bigger size homes. over 40 pyung place higher value on brand name, trends. or coordinating existing furnishing with new products than residents in smaller units. However, women who live in smaller units place higher value on functionality when purchasing home fashion products. Considering factors such as brand, trend, and materials were also significantly associated with segmented age group; 40~49 age group considered brand, trend, and materials more than 20~29 age group. The group who are highly interested in home fashion considered design/color, rand, coordination, and functionality than the group who are low interested in home fashion. 2. Residents in over 40 pyung homes buy home fashion products at department stores, while residents in less than 39 pyung homes buy them at discounted store. 3. Respondents preferred solid colors more than patterns. However, they favored character pattern for textile bedding products for their children. 4. there is also a statistical difference in preferences for types of window treatments between large ad small housing sizes. Residents living in over 40 pyung preferred tie-back/cottage curtain, while residents living in less than 29 pyung preferred Roman shade style.
