This study was aimed at primarily to develop a tool to evaluate sexuality education and secondarily to test effectiveness through application of developed evaluation tools in elementary school. The results from this study were summarized below: 1. On the basis of targeting the lower grades (1st- 3th year) and the higher grades (4th-6th year) elementary school students' sexuality education guidebooks published by Korea Ministry of Education & Human Resources Development, 71 preliminary items targeting the lower grades, 90 preliminary items targeting the higher grades were developed. 2. Through the validity test about the contents of the preliminary items three times, the items were regulated to 65 items targeting the lower grads and 57 items targeting the higher grades. And then, the preliminary items were re-regulated to 40 items separately. Then, pre-test which targeting each 30 students was enforced. 3.Finally, the evaluation tools for sexuality education that consisted of 40 items targeting the lower grades and the higher grades were developed. 4. eliability test of the developed tools, sexuality education evaluation tools showed alpha coefficient of internal consistency were 0.8355 (for the use of the lower grades) and 0.8881 (for the use of the higher grades). 5. o apply the developed sexuality education evaluation tools, 10-times sexuality education were carried out class unit and pre-post test were done using same questionnaire, which contains developed tool, there were significant difference in low grade (t=16.548, p=0.000), high grade (t=14.773, p=0.000). The results of this study suggest that the evaluation tool for sexuality education in elementary school may be a useful tool with a high degree of reliability and validity. In this sense, the evaluation tool for sexuality education developed by this study can be effectively utilized in Korea elementary schools.

This study comparatively examined the environmental affordance of elementary children's rooms between the lower and the higher grades, and investigated the affects of the rooms'affordance on children's satisfaction of the rooms. Survey questionnaires were given to 412 elementary school children(221 in the lower grades and 191 in the higher grades), including their parents. Frequency analysis, $x^{k}$ -tests, t-tests, correlation tests, and regression analysis were mainly employed for the data analysis. The findings indicated that the environmental affordance of the children's rooms differed in each group in terms of the four dimensions: Social interaction, privacy, safety, and uniqueness. Meanwhile, the more environmental affordance was sufficient, the higher degree of the satisfaction was showed. In the lower grades, conveniency, accessibility, social interaction, and uniqueness were influenced their satisfaction of the rooms, whereas social interaction, conveniency, order, and privacy were affected the children's satisfaction in the higher grades.

A transition from elementary to secondary school, and among grades, among learning contents is a essential problem in education. A connectivity between learning contents is important in student's growth and development. A gap between lower grades and higher grades in elementary school is no less extensive than a gap between elementary mathematics and secondary mathematics. In this paper, we start with a critical mind about a transition and connectivity between lower grades and higher grades in elementary school. In order to compare between elementary grades, we firstly focus 4th grade mathematics which finish lower grades and start higher grades at the same time. First, we make up a questionnaire to 4th grade students and teachers in charge 4th grade. A questionnaire is composed of questions about the degree of difficulty in the learning(and teaching) of 4th grade mathematics comparing with 3rd grade mathematics. Second, we compare to lower grades lessons(1st grade) and 4th grade lessons using a qualitative method. we analyze the lesson contents, activities and time through 'analysis of the learning course'. And we compare the pattern of eliciting questions, question patterns, nomination patterns and feedback patterns between 1st grade and 4th grade lessons. We hope that this paper is a fundamental sources in investigating a connectivity between lower grades and higher grades in elementary mathematics in the future.

Six muscles were seamed out randomly from Hanwoo carcasses (n = 12) of each quality grade (quality grades 1, 2 and 3). Samples were analysed for their total and soluble collagen contents, IMCT (intramuscular connective tissue) and Warner-Bratzler shear force (WBSF). Simple correlation (n = 21) was determined for WBSF among major muscles. For LT (longissimus thoracis), total collagen content was significantly higher (p<0.05) for quality grade 3 than those for quality grades 1 and 2. For semitendinosus (ST), semimembranosus (SM), psoas major (PM) and serratus ventralis (SV), total collagen content of quality grade 1 was lowest (p<0.05) of all quality grades. IMCT shear force for gluteus medius (GM) decreased (p<0.05) with better quality grade, and those for other muscles, with the exception of GM, were higher (p<0.05) for quality grade 3 than for quality grades 1 and 2. WBSF values showed GM and LT to be decreased (p<0.05) with better quality grade, and PM to be higher (p<0.05) for quality grade 3 than those for quality grades 1 and 2. SM, ST and SV from quality grade 1 had lower (p<0.05) WBSF value than those from quality grades 2 and 3. Total collagen content of ST was highest (p<0.05) of all muscles, whereas that of PM was lowest (p<0.05). Soluble collagen contents of LT and SV from quality grades 1 and 2 were, in general, higher (p<0.05) than other muscles, but that of SM was lowest (p<0.05). ST and SM had higher (p<0.05) WBSF values for three quality grades when compared to other muscles, whereas PM was lowest (p<0.05). LT had the strongest simple correlation with SV (r = 0.78) and GM (r = 0.77), and SM had the strongest correlation with ST (r = 0.73) and LT (r = 0.73). Also, PM had the strongest correlation with SV (r = 0.62).

Objective: The aim of this study was to compare gait patterns of elementary school male students in higher grades according to their character styles. Method: 4 extroverted character male subjects (height: $141.35{\pm}7.75cm$, weight: $43.65{\pm}5.80kg$) and 4 introverted character male subjects (height: $145.38{\pm}8.94cm$, weight: $42.15{\pm}10.71kg$) participated in this study. Results: As for walk styles of elementary school male students in higher grades according to their character patterns, there was not significant differences in gait cycle, stride width, stride length and walking speed. According to examination of average ratio of maximum vertical ground reaction force according to their characters divided by weight, elementary school male students in higher grades with extroverted character showed 114.69% of weight and students with introverted character showed 122.82% of weight, which exhibited that students with introverted character had larger ratio as much as 8.13% than students with extroverted character. The statistical significance level was 0.000 showing significant difference. Conclusion: Our results indicated that male students in higher grades with introverted character press ground hard and walk with strong steps. On the other hand, male students with extroverted character walk with light steps.

The purpose of the present study was to examine the relationship between sentence repetition and sentence production in school-age children. The participants included 120 school-age children through 1st to 6th grades who were then divided into three grade groups (lower grade: 1st to 2nd grades, intermediate grade: 3th to 4th grades, and higher grade: 5th to 6th grades). The repetition task consisted of 32 sentences that were classified by sentence length (5, 6, 7, and 8 words) and structure (conjunctive and embedded sentences). The sentence production task utilized Lee's (2007) grammaticality judgement and sentence combining task. The findings of present study were as follows. (1) The higher grade performed significantly better than the lower and intermediate grades. (2) The participants performed significantly worse when imitating longer sentences than when imitating shorter ones. In addition, there were interaction effects between grade groups and sentences length. (3) The participants performed significantly better when imitating conjunctive rather than embedded sentences. (4) There was significantly positive correlation between the sentence repetition and sentence production task.

Colleges of technology in Japan are characterized by specialized education starting from the first grades aged fifteen, making it particularly important to provide motivation for specialized subjects. The most difficult thing for teachers in the technical college is giving the motivation to a professional education to the lower grades who don't know the technology and engineering. Teachers tried to use and make a suitable example or an education material for their lecture. The generation gap with students makes it difficult for teachers to use examples of objects that students are actually familiar with in their daily life. To compensate for the generation gap with students, we asserted that education for lower grades should adopt the perspectives of students in higher grades. The relative closeness in age of lower and higher grades helps reduce the generation gap with students, which is advantageous in that teachers can share the perspectives of students.

This study is conducted in grades 4, 5, and6 of Elementary schools located in Seoul. The results would be recognized by the Consumer Behavior Survey and the Use of Beauty. Students in the higher grades of elementary schools are exposed to beauty products for the first time. This is a crucial age, where they start becoming interested in their appearance. This behavior is being exploited to increase the desire to use beauty products. Although the initial use is self-motivated, choosing a quality product is highly influenced by peers, reasonable pricing, and internet impact. The higher the grade of the elementary school, we observed an increase in this trust and impulsiveness in the consumer behavior. More than 2 million students spent considerable amounts of money, and showed trends of consumer behavior of the impulsive type. The results of this study can provide a significant base to further study trends of beauty usage in higher grades of elementary schools, and give an indication of the consumer behavior based on the beauty culture and use of health products.

The purpose of this study is to analyze the differences of food habits and food preferences between lower and higher grade students through the survey of elementary school students in Daejeon four elementary schools located in Jung-Gu and Seo-Gu in Daejeon are selected for this survey randomly and the completion of the questionnaires are according to grade. 1. Practical Analysis of Food Habits: For regular meals, the highest number of subjects skipped breakfast. It is being found that the girl students (81.61%) consumed more cooked rice than the boys (78.85%) and more boys (13.10%) ate bread or milk more than the girls (9.20%). The most important thing for the lower grades students (34.20%) when consuming is the nutritious foods, while the higher grades students (49.67%) consumed the set meals. During consumption, the highest number of the subjects watched TV or read books from time to time. More higher grades students (38.98%) preferred spicy and salty foods than the lower grades (22.09%). 2. Food Preferences: Between rice and noodles, most subjects preferred cooked rice (81.38%), Jajangmyeon (80.80%), Ramyeon (79.43%), and disliked bean-mixed rice (28.39%). For soups, Most students enjoy the Deokkguk. Majority of the subjects prefer meat and fried or steamed foods, and also grilled and pan-fried dishes. For the pan-roasted and fried dishes, most subjects did not enjoy the rhizome fry and sweet-pumpkin fry methods, and for vegetables, they did not like wild vegetable and seasoned cucumber (40.57%) The higher grades students enjoy the vegetables and salads more than the lower grades students. For Kimchi varieties, it is found that subjects like the cabbage Kimchi (69.66%) the most. There is little difference in food preference between the lower and higher grade students, but the rankings of food preferences are different according to various grades.
