The purpose of this study is aimed at giving proof that helps the elementary practical arts education system accomplish as the effects are turned out experimentally. Two classes of the sixth grade of J elementary school in Dae-gu have been selected in order to be experimented. One was chosen as an experimental group, the other was done as a comparative group. The creative-problem-solving learning-model was applied to the experimental group, and the traditional way of teaching was applied to the comparative group. For four classes of the sixth grades, ‘chapter 8: Making with recycled materials’ was proceeded as the content. Then. tests about the way of environmental awareness and creativity were carried out twice. After that, the results of pre and after-test in the comparative and experiment groups were compared using the t-test method. Following the analysis of the data collected in this study. the following major observations were obtained: First, children who were educated the creative problem-solving in a practical arts education achieved higher scores than before. Therefore, it turns out that the CPS method is an effective way to improve the environmental awareness in children. It showed that it included lots of daily habits connected with daily life and it made the intention to carry out the environment-preservation stronger and children´s attitude towards the environment improved. Moreover, making with recycled materials was used to solve an environmental problem, affecting in a positive way in our life. It also made the positive recognition about the environment. Second. the application of the creative problem-solving class of the practical arts education can make positive results to children. It helped children to have more interest in the environment around them. Children´s fluency, flexibility and originality in their ideas were improved as much as possible while they were solving problems. Consequently, the application of the creative problem-solving class model of elementary practical arts environmental education lets children expand environment consciousness and creativity.

It is important to control fine particles in children care centers, elementary schools, elderly care facilities and so on where vulnerable children and the aged stay during most of their time. This study has investigated $PM_{2.5}$ and $PM_{10}$ concentrations in two classrooms equipped with an air cleaner and two air cleaners, respectively and they were compared to those in a classroom without an air cleaner as well as those outdoors. Eight air cleaners which have various clean air delivery rates (CADRs) between 9.9 and $21.3m^3/min$ were tested in classrooms in two elementary schools in Seoul. Average $PM_{2.5}$ and $PM_{10}$ were $7.3{\pm}0.7$ and $45.5{\pm}4.1{\mu}g/m^3$ in classrooms equipped with an air cleaner and $4.2{\pm}0.6$ and $24.6{\pm}2.5{\mu}g/m^3$ in classrooms with two air cleaners, whereas they were $22.1{\pm}2.6$ and $109.1{\pm}9.6{\mu}g/m^3$ in classrooms without an air cleaner and $36.9{\pm}5.1$ and $74.1{\pm}10.6{\mu}g/m^3$ outdoors, respectively. $PM_{2.5}$ in classrooms could be reduced effectively by using an air cleaner or two air cleaners, because $PM_{2.5}$ was mainly infiltrated from outdoors, however $PM_{10}$ could not because $PM_{10}$ was mainly caused indoors by students' activities. Air cleaners were more effective for removal of $PM_{2.5}$ and $PM_{10}$ in classrooms with a high airtightness than those in classrooms with a relatively low one. Average $CO_2$ in classrooms was about 1500 to 2000 ppm for class hours dependent on the student number per a classroom, which was about 1.5 to 2 times higher than the standard, regardless of the use of air cleaner.

The purpose of this study is to introduce and research the traditional Korean costume collections of Dr. McCune who was born in Pyung-Yang in 1907 and resided until her marriage to George S. McCune in about 1930. Her collections consist of three categories : children's costumes, adults' costumes, access-ories. The characteristics of collections are summorized as follows : 1. Deep wrappings are found at the front part of the top clothing when worn. The front gusset (SUB) has been dramaticaly tilted due to the difference in lengths of the top and bottom parts of the front gusset. 2. Assymetry was one of the principles of decorating Korean costumes. The assymetry were repeated at the GIT and SUB of CHOGORE with patchwork patterns. 3. Primary colors were favored in Korean costume. Hue contrast in color combinations was prefered as well, such as : yellow CHOGORE and purple blue CUFFS, a red SUN pattern matched with green embroidery. 4. Surface patterns were not so popular in Korean costumes, while the most colorful and fabulous patterns were shown through the various embroidery artifacts. Patterns were used as a way of expressing of their desires or longings in Korean costumes. The main themes of the patterns were longevity and happiness. The patterns such as peony, lotus, chrysanthemum, bamboo and bat were implying symbolism at that time. 5. Natural materials were prefered for the garments, Silk and cotton were used as the main materials of the costume collections. Studies of Korean Costume collections owned by international collectors are meaningful to boost the arena of Korean Costumes as well as fill up the vacancy left by lost costume artifacts.

Death of spouse is the most heartbreaking stressful and inevitable tragic life event. In middle aged men who belong to the social middle class and accomplished their occupational success, experiences of spousal bereavement are great shock. The aim of this study was to find out how they overcome their mental and physical pain and to obtain the basic materials to develop suitable nursing care programs for them. The methodological approach of this study is Giorgi's phenomenological analysis meaning unit. This method also makes theme focal meaning, situated structural description and create general structural description grasped by participator's experience through situated structure description. This study performed from November 2002 to May 2004, and participators were four men. Data collected through in-depth personal interviews. which had been tapped and analysed the Giorgi's method. Finally, the five focal meaning below have been abstracted. Theme 1. Physical symptom loss of appetite, fatigue, insomnia. outbreak of illness, weight loss. Theme 2. life of spiritless lack of desire, sense of emptiness, unstableness, prosaic life. wandering. indifference of appearances, avoidance of meeting people. Theme 3. life of retrospction reflection for his wife, yearning, grief, muttering to himself, never-to-be forgotten wife, leading a lonely life. Theme 4. negative emotion reproaching, feeling hurt, marriage of daughter, feeling heavy, getting angry, sexual desire, awareness of his sinfulness. loneliness Theme 5. social support and adjustment getting his wife off his mind, curring favor with children, support and consolation by his daughter-in-law, appreciation for hospice nurse, considering remarriage, taking care of himself, good relation with his children. The result of this study showed that middle aged men bereaved of their wife by cancer need other's concern. And we have to study further to understand their experience. Until now hospice nursing is concentrated on cancer patients But from now we have to provide their families suitable nursing care programs to adjust themselves to social life before and after death of patients.

This study aims to be the useful resources for selecting play therapy facility in the future by analysis of used colors in the play therapy facility as the subsequent studies of the thesis of KIID in 2010, titled 'Study on the planning factors of case study for children's play therapy center'. As research method of this study, the overall understanding about play therapy facility was improved through theoretical considerations, and it was about the Moon-Spencer's theory of color harmony which will be used for the framework of case study. In Section 3, the field trips at 6 facilities were conducted as the case research and the data research through website was conducted for case study. Moon-Spencer's theory of color harmony used the Munsell's color Order System, so after measuring CMYK value of the picture for the case research through photo shop, the color, brightness and saturation were measured through Munsell Conversion program. The following three kinds of features were drawn by research of the harmony and disharmony of used colors for the cases after substituting the theory of color harmony through the measured color. brightness, and saturation. First. series Y and YR were used mainly for warm image as the concept of play therapy room. Second, the various colors were used for comfortable image like home. But the various patterns were used by mixing for the therapy room F, so it gives confusing impression. Third, series YR and achromatic color as the color of wood were used unavoidably for using materials of manufactured goods.

Background: There are limited studies on oncoplastic breast conserving surgery in Asian women. We aimed to determine the applicability and safety of oncoplastic surgery, highlighting the specific circumstances when it will be most useful and compare our preferred technique with the worldwide practice of oncoplastic approaches. Materials and Methods: Breast cancer patients who underwent oncoplastic breast conserving surgery at a single institution from 1st May 2014-31st March 2015 were included. Data on patient demographics, tumor characteristics and the type of oncoplastic surgery performed were collected. Results: Nineteen breast cancer patients were identified. 42.1% of patients had grade I ptosis. The indications for surgery included a large tumor to breast size ratio (52.6%), multifocal/multicentric lesions (36.8%) and asymmetric breasts (10.6%), averting a mastectomy in 89.4%. Round block was the commonest technique in 63% of patients, in contrast to the inverted T pattern most frequently used in renowned institutions in the West. Mean and median tumor size and weight of specimen were 29.4/25mm (11 - 75mm) and 77g/64g (10 - 246g) respectively. Re-excision rate was 10.5%. Complete mastectomy was performed for one patient. One patient developed wound dehiscence which was treated conservatively. Cosmetic outcome was rated as excellent/good by 94.7% of patients. The patients remained clinically well after a median 16 months follow up. Conclusions: Oncoplastic breast conserving surgery is useful in a specific subgroup of Asian patients with a relatively small breast volume and minimal ptosis. Round block was the commonest technique in our series, in contrast to the worldwide utility of oncoplastic techniques. It is oncologically safe and has good cosmetic outcomes.

The purpose of this paper is to present a specific set of home teaching methods in hopes to prevent slow learner of the elementary mathematics. This paper deals with the number and operations, one of five topics in the elementary mathematics A survey of two hundred elementary school teachers was made to see the teacher's opinions of the role of home studying and to concretize the contents of the research topics. There were asked which is the most essential contents for the concrete loaming and which is the most difficult monad that might cause slow leaner. And those were found to be; counting, and arithmetic operations(addition and subtraction) of one or two-digit numbers and multiplication and their concepts representations and operations(addition and subtraction) of fractions. The home teaching methods are based on the situated learning about problem solving in real life situations and on the active teaming which induces children's participation in the process of teaching and learning. Those activities in teaching each contents are designed to deal with real objects and situations. Most teaching methods are presented in the order of school curriculum. To teach the concepts of numbers and the place value, useful activities using manipulative materials (Base ten blocks, Unifix, etc.) or real objects are also proposed. Natural number's operations such as addition, subtraction and multiplication are subdivided into small steps depending upon current curriculum, then for understanding of operational meaning and generalization, games and activities related to the calculation of changes are suggested. For fractions, this paper suggest 10 learning steps, say equivalent partition, fractional pattern, fractional size, relationship between the mixed fractions and the improper fraction, identifying fractions on the number line, 1 as a unit, discrete view point of fractions, comparison of fractional sizes, addition and subtraction, quantitative concepts. This research basically centers on the informal activities of kids under the real-life situation because such experiences are believed to be useful to prevent slow learner. All activities and learnings in this paper assume children's active participation and we believe that such active and informal learning would be more effective for learning transfer and generalization.

Objective: This study aims to analyze parents' perception of the suitability of the 'Childcare Support Center (C.S.C.)' and the 'Early Childhood Education Promotion Institute(E.C.E.P.I)' as home care support service providers. Methods: The goals and content of the home parenting support service offered by the C.S.C. and E.C.E.P.I. were analyzes based on information collected from their websites, publications, and various promotional materials. There were categories into 18 services across 5 categories. Responses of 421 parents, gathered through a questionnaire developed with reference to previous studies, were collected and analyzed. Results: Parents reported high degree of suitability for the organizations they used. Those familiar with both institutions found E.C.E.P.I. more suitable overall. However the C.S.C. was considered particularity suitable by parents of children aged 0-2 years and by those with no prior experience with either institution. The perceived suitability of the two institutions varied by service, depending on factors such as the age group of the children, whether the parents lived in the metropolitan area, and whether they were part of a double-income household. Conclusion/Implications: These findings have practical implications for development of integrated policies for early childhood education and childcare, which should take into account parents' perceptions of the functions of institutions.

Information regarding the status of lunch box service for children and juveniles from nutritionally vulnerable families is limited and has not been assessed from the view of beneficiaries. Therefore, this study intended to determine the satisfaction, current status, menu preferences, and dietary habits of recipients served lunch-box meals from Pocheon city. There were 41 subjects from primary schools and 73 from secondary schools. Although 94.8% answered that the foods were generally helpful, as much as 28.9% replied that the amount of food provided was too little. Only 77.2% answered that they eat the foods always or usually, 29.5% answered that they throw away leftover foods, and only 71.9% recycled empty containers, suggesting the need for instruction regarding how to deal with leftover foods and containers. Food preferences were high for deep-fried foods and meats and low for fish and vegetables, and that for vegetable egg rolls was relatively high, suggesting the need to increase vegetable intake. Adherences to guidelines regarding street foods was the lowest in both elementary and secondary school students, suggesting that the contents of nutrition education for these students should include materials to improve dietary habits, along with increasing the consumption of milk.

The purpose of this study was to seek desirable direction of science teaching and to present meaningful ideas for implementing the science curriculum and teaching materials by measuring the degree of the students' understandings on science and comparing it with those of American students. The researcher comprised 790 primary and middle school students for the study and administered them questionnaires developed by Trowbridge, Bybee, and Sund. The questionnaires were analyzed along with three categories such as science method, science theory, and the achievement of scientists. The researcher used t-test and ANOVA in order to compare the difference of their understandings in accordance with grades and gender, and later compared Korean students' understandings with those of similar aged American students administered by the National Assessment of Educational Progress (NAEP) The research loathed to the overall conclusions as follows; Both primary and middle school students' understandings on science revealed positive and appeared no significant difference in gender. And it is thought that science education was being carried out hopefully to enhancing Korean students' scientific literacy, therefore, science teaching like what is implemented to the classrooms currently should be kept on in future. On the other hand, it is necessary to change primary school children's understandings on attitude and value of scientists while to change middle school students' understandings on scientific processes by experiment. Also primary school children need to understand that scientists are willing to change their ideas when new information becomes known.
