When most middle-aged women live in a time when they have to take responsibility for their lives, they feel lonely when they realize that their experience of not expressing their feelings properly has ended up being left alone due to their own existence and loss. As the first step in conscious awareness of unconsciousness of middle-aged women through analytical psychology, we performed "Mandara" and "Nanhwa Mandara," which meet me inside. The intermediate stage can be divided into transition and work phase. The working phase, develops one's own advantages and unique strengths that meet the inner world of promoting and acting values, correctly looks at reality, corrects emotion perception and balance, and is self-contained, seed mandala, associative mandala. They performed the strong points of mandala, the free mandala, and the Western mandala. The results of the study showed that mandala art therapy was found in middle-aged women. First, Mandarin art therapy experience affects the physical, psychological and human relations aspects of middle-aged women. Second, middle-aged women's experience of individualization through mandala art therapy shows psychological reversals and affects positive thinking and self-effectiveness. This study was suitable for qualitative research that approached the essence through practical understanding and direct exploration of research participants, and it is meaningful to suggest that it is necessary to develop an art therapy program through various mediums considering the lack of art therapy research in middle-aged women and problems experienced by the physician.

KASUMI is a 64-bit iterated block cipher with a 128-bit key size and 8 rounds Feistel structure. In this paper, we describe saturation attacks on the five round KASUMI, which requires 10 $\times$$2^{32}$ chosen plaintexts and $2^{115}$ computational complexity We also improve this attack using meet-in-the-middle technique. This attack requires 7$\times$$2^{32}$ chosen plaintexts and $2^{90}$ computational complexity. Futhermore, we attack KASUMI by controlling the value of the fixed part of the key. This attack needs 3$\times$$2^{32}$ chosen plaintexts and $2^{57}$ computational complexity.

This study aims to derive the need for middle-aged women to consider using fashion product applications, styling, and personalized styling services. To analyze the fashion styling considerations of middle-aged women, 200 women in their 40s and 50s were surveyed. Middle-aged women usually tend to shop through home shopping, department stores, fashion soho (Small office home office) malls, and open market-type applications, and purchase fashion products more than two or three times a month, spending an average of less than 50,000 won per month. Middle-aged women consider choosing appropriate clothing based on the occasion and place, complementing the flaws of the changed body type as well as taking into account the weather in the styling process, and seek to showcase a sophisticated, luxurious, and youthful image through styling. However, they are confused and face difficulties in fashion styling, with regard to not only overall body shape but also partial body changes, such as increasing waistline, flabby thighs and arms, and decreasing hip volume. In addition, middle-aged women were looking for expert advice on styling to help them look the best. They also wanted to solve the difficulties of making a right choice amid the overflowing information related to fashion. The results of the study contribute to identifying products that meet the needs of middle-aged women and help develop detailed consumer-tailored marketing strategies, thereby improving sales of fashion products.

The purposes of the study were to analyze nutrients of the menus served and to evaluate students' nutrient consumption at school food services. Three middle schools (boys, girls, and co-ed schools) were located in Seoul and Kyunggi Province. A weighed plate method was employed to measure plate wastes and consumption of the menus served. Data was collected for 3 consecutive days at each school. Nutrient analyses for the served and consumed menus were performed using CAN-PRO. On average the students consumed $67\%$ of the menus they were served. By menu category, the students consumed more than $90\%$ of the rice and one-dish foods they were served. Kimchis ($54\%$) and soups/stews ($55\%$) were the menu categories with the lowest consumption rates. The menus served at the boys and coed schools did not meet 1/3 of the recommended daily allowances (RDA) for calcium, iron, and vitamin $B_2$. Due to the plate wastes, the actual consumption of the boys school students did not meet the 1/3 RDA for calories, calcium, iron, vitamin A, vitamin $B_1$ vitamin $B_2$ and niacin. The menus served at the girls school exceeded the 1/3 RDA for all nutrients, but the actual consumption did not meet the 1/3 RDA for calcium, iron, and vitamin $B_2$. During the 3-day periods, the served and consumed menus provided $27\%$ and $24\%$ of energy from fat, which exceeded the recommended proportion of $20\%$. To improve nutrition management at school food services, dietitians should understand factors that influence students' consumption and implement nutrition education programs that emphasize balanced diets.

Steel FibreReinforced Shotcrete(SFRS) is one of the main tunnel support along with the rock bolt during the excavation and after the completion of the tunnel. In the standard qualification of the SFRS defined by Korea Highway Corporation, 28 day core specimen has to meet the compressive strength of 19.6 MPa and over 90 % fibre contents. Furthermore, for the 28 days brick shaped specimen made by shooting, flexural strength should be over 4.4 MPa and flexural toughness ratio which can be calculated from flexural toughness factor has to meet more than 68% of flexural strength. In shotcrete, accelerating agent is added for the rapid strength development. Silicate and aluminate type agents are known to develop shotcrete strength rapidly, however, has such problem to degrade the middle and long term strength. Hence, using poly carboxylic super plasticizer, it was aimed to enhance the quality of the shotcrete with the lower water-cement ratio and the same level of workability. The present paper shows the part of the field test result and its analysis.

Background & Objectives: The current study aims to convey correct knowledge of dementia that is be on the rise as the most significant social problem and provide basic data for implementing immediate school health education for dementia which is the basis of improving quality of life for patients with dementia, their family and the society by analyzing recognition level for dementia among male and female students in the 2nd grade of middle school and the necessity of school health education for dementia. Methods: The current study conducted a survey with a total of 150 students. 25 male and female students respectively selected from three middle school taking into account regional characteristics. The study also processed the survey results using SPSS-PC Program 12.0 and gained the following results by implementing Frequency Analysis. Cross-tabulation Analysis and ANOVA Analysis. Results: As for respect for grandparents, 55.3% of the respondents said they respect their grandparents. while 39.3% answered so-so and 5.3% said they don't respect their grandparents. As for the number of they meet grandparents, 36.0% of the respondents said they meet grandparents once or twice a month, which was the most frequent answer. On the other hand, 24.7% are once or twice every six months, 13.3% are once or twice a year and a week, respectively, and 6.7% said that they seldom meet their grandparents. In a question about whether they had recognized dementia after explaining dementia in detail, 82.7% said' yes' while 17.3% said' no'. But few students recognized it when they were asked using a terminology' dementia' first. The average score of knowledge level integrating the most fundamental 16 questions about dementia was $11.20{\pm}1.73$. Also 83.3% of the respondents answered that they had no experience in health education about dementia while 16.7% said presented positive answers. In the necessity of health education about dementia, 73.3% of them said' necessary' while 21.3% said' so-so' and 5.3% said 'not necessary. Conclusions: From the above study results, it was found that it is time to emphasize the necessity and importance of school health education for improving respect for the old and a sense of responsibility for support and converting recognition for dementia in Korea that has social structure of the trend toward the nuclear family and heads for an aged society. However, the fact that the above things are not implemented at all in reality can expand disparate views among family members in the future and further can cause even more serious problem by neglecting senior problems. Therefore, the government, social organizations, especially school organizers should recognize the necessity and importance of school health education and actively begin cultivations of students' character by implementing the education about dementia at the early stage.

The purpose of this study was to provide preliminary data for better safety control over children's preference foods sold in school stores. The survey was conducted from June to July 2009, to collect 749 types of children's preference foods sold in 150 middle and high school stores nation-wide excluding Jeju Island and general and nutrition information were analyzed. Out of 749 types of snack food items, 689 and 602 snacks were sold at high school and middle school stores respectively. Among children's preference foods, cookies, bread, and ice-cream were the main items. Among them, 98% of snacks were domestic products and the price range of each individual snacks were mostly between 600 and 900 won. 27.8% of children's preference foods sold were found to be in the high calorie/low nutrition food group. Even though the proportion of candy and fruit/vegetable beverages sold were not high, their proportion in high calorie/low nutrition snack group were higher than 68.1%. Among the children's preference foods sold in middle and high school stores, carbonated drinks and ramen were continuously sold in certain middle and high schools, even though sales were prohibited. This study concludes that government, corporations and retailers should work together in developing healthier children's snack distribution environment. In addition, dairy products, which take up 15% of children's preference food, should be diversified to meet their nutrient requirements.
