The present study analyzed data from the 3D measurement of the feet of men aged over 20 years residing in the capital region as part of the 6th Anthropometry of Size Korea. To analyze the characteristics of the foot shapes of young men aged 20~39 years and middle-aged/elderly men aged 40~69 years by age and by type, a cluster analysis was conducted using the factors derived through the factor analysis as independent variables. The results of the study that analyzed the characteristics of foot shapes by type according to differences in age were as follows. First, through the analysis of the characteristics of the foot shapes of young men by type, five factors were extracted, and the foot shapes were classified into three types: Type 1 (short and flat), Type 2 (thick), and Type 3 (long and wide). Second, through the analysis of the characteristics of the foot shapes of middle-aged/elderly men by type, six factors were extracted, and the foot shapes were classified into four types: Type 1 (short and regular), Type 2 (flat), Type 3 (thick), and Type 4 (long and regular). The results of the present study are expected to serve as basic data for the design of shoes by age and foot type.

이 연구의 목적은 중학교 천문 수업에 대한 과학 교사의 교수 실행에서 나타나는 시스템 사고를 분석하는 것이 다. 이를 위해 4명의 중학교 8학년 과학 교사의 천문 단원 수업을 녹화하였고 녹화된 수업은 모두 전사하였으며, 선행 연구의 시스템 사고 위계 구조를 수정하여 개발한 시스템 사고 분석틀을 적용하여 이들을 분석하였다. 또한, 수업 분석 후 참여 교사의 과학 수업에 대한 지향과 교수학적 생각을 심층적으로 분석하기 위해 비디오 자극 회상 면담을 실시하 였다. 연구 결과는 다음과 같다: 모든 참여 교사들은 천문 수업에서 시스템 사고의 위계를 제대로 반영하지 못하였으며, 낮은 수준의 시스템 사고만을 활용하는 것으로 나타났다. 또한, 교사가 학생 중심의 교수 지향을 지녔다 하더라도 시스 템 사고의 교수 실행은 교사 중심으로 진행되는 것으로 나타났다. 천문 수업의 교수 실행에서 시스템 사고가 부족하게 나타나는 것은 공간적 사고에 보다 집중하는 것과 지구과학 비전공 교사로서의 천문 내용 및 형성 평가 지식 부족 때 문인 것으로 판단된다. 이러한 연구 결과를 바탕으로 천문 수업에서 효과적인 시스템 사고의 도입 방안을 논의하였다.

With an effort to verify the involvement load hypothesis, this study investigates the effects of three different vocabulary learning tasks - reading, filling in blanks, and sentence writing - on learners' short and long term memory when they are provided with the theoretically identical level of involvement tasks. It is also to examine whether there are any differences of learning effects between input and output vocabulary learning tasks. The experiments were conducted with 86 Korean middle school students grouped by three different task types. Pre-/post-tests and delayed tests were administered and analyzed. It was found that three vocabulary tasks with theoretically identical levels of involvement do not have the same learning effects: the involvement load hypothesis was not completely proved in the case of Korean students' vocabulary learning. The findings implied that (i) the difference of vocabulary learning tasks should be considered even though they have the same involvement load; (ii) given that EFL students learn new words in a limited amount of time in class, the reading task using a dictionary is found to be very helpful; and (iii) it is important to study target vocabulary repeatedly during class and to expose the vocabulary with different tasks to enhance students' retention of the newly learned vocabulary.

The apparel industry has recently been recognizing the important target market of middle-aged women. The aim of this study was to examine the anthropometric characteristics of US women of 46 to 65 years of age and identify distinctive body shape characteristics of US middle-aged women. A total of 1915 middle-aged women whose ages ranged from 46 to 65 were selected from the SizeUSA database. The age range was divided into two groups: 46-55 and 56-65. Twenty-four body measurements important for apparel development were chosen. Four factors—Girth Factor, Height Factor, Hip Drop Factor, and Bust Drop Factor—accounted for the US middle-aged women’s body measurements. The body shapes were classified into four body shapes, which were Y-Shape in the overweight range, S-Shape in the overweight range, H-Shape in the overweight range, and the A-Shape in obese range. H-Shape, which was the least-defined waist in relation to the bust and hips with a short height, existed more in older middle-aged women than in younger middle-aged women. Y-Shape, S-Shape, and A-Shape existed more in the group of younger middle-aged women than in the group of older middle-aged women. In addition, compared with the younger middle-aged women, older middle-aged women had narrower shoulders, a larger waist, thinner legs, and a longer distance between side neck to bust point. The findings from the current study may be applied in the apparel industry for developing clothing sizing systems for US middle-aged women.

This study was conducted to provide desirable way on the eating of sugar foods, specifically the differences between dietary attitude, dietary behaviors and intake frequency. Data was collected from 279 middle students in the Incheon region through a self-administered questionnaire. According to the results of the reliability and factor analysis, the dietary attitude, dietary behaviors and intake frequency was 3.52, 2.89 and 2.51, with a Cronbach alpha coefficient of 0.867, 0.789, 0.940 and KMO of 0.899. Factor analysis extracted three components of the sugar preference, which we named dietary attitude (factor 1), dietary behaviors (factor 2), and intake frequency (factor 3). The dietary attitude and dietary behaviors showed a significant difference between sugar preference and non-preference (p<0.05). Also, intake frequency of sugar food showed a significant differences in chocolate, chocolate products, and ice cream between sugar preference and non-preference (p<0.05), whereas no significant differences were found in cake, bread kinds, juice, sweetness milk, yogurt between sugar preference and non-preference (p>0.05). A significant positive result of intake frequency of sugar food (p<0.05) was shown for the dietary attitude, BMI, weight, and monthly pocket money. Based on this study, the reduction of sugar intake is needed especially for middle students

The aim of this study was to investigate the change in women’s somatotype with aging. The subjects were 1,123 women aged 40~69. Their anthropometric data were from the 6th Size Korea. The data were analyzed by factor analysis and cluster analysis. Seven factors were extracted: body mass, body length, back shoulder, arm length factor, front interscye factor, body rise factor, and shoulder angle. The upper body types of middle-aged and elderly women were classified into five types: skinny, short stout body type with forward posture, composite, tall & full body type, and short & skinny. The skinny and composite body type appeared more often than the short stout body type in the early 40s of Korean women. Starting in the mid-50s, composite body type was less often found. However, the number of women with short stout body type increased. In the 60s, the number of women with short stout and tall & full body types decreased. These results reveal that the body types of middle-aged and elderly women changed with some pattern with aging. And women in their early 40s, mid-50s, and 60s women had different body shapes and postures.

본 시험은 새로운 여름 사료작물인 케나프(kenaf; Hibiscus dannabinus L.)의 생육특성, 수량성 및 품질을 다른 사료작물과 비교할 목적으로 2013년부터 2014년까지 2년간에 걸쳐 축산과학원 축산자원개발부 초지사료과 내의 시험포장에서 수행하였다. 중부지역에서 케나프(홍마 300), 옥수수(광평옥) 및 수수×수단그라스(점보)의 생육특성 및 품질을 비교한 결과를 요약하면 다음과 같다. 당도는 홍마 300이 5.4 Brix°로 광평옥보다 1Brix°, 점보보다 2.9 Brix° 높았다. 출현율과 도복은 세 작물 모두 각각 80% 이상, 1.5 이상으로 양호하게 나타났다. 생초수량은 점보가 홍마 300보다 12% 높았으며, 건물중은 홍마 300이 제 작물 중 유의성 있게 가장 높게 나타났다(p<0.05). 하지만, TDN 수량은 홍마 300이 광평옥보다 13% 유의성 있게 낮았다(p<0.05). ADF 및 NDF 함량은 홍마 300이 57.8%, 69.5%로 가장 높았으며 TDN 함량 및 건물소화율은 43.3% 및 44.4%로 가장 낮았다. 따라서 본 연구결과를 토대로 볼 때 케나프인 홍마 300은 건물수량은 높지만 사료 품질에서 광평옥 및 점보보다 많이 낮았다. 그 결과 TDN 수량성은 광평옥보다 13% 낮은 결과를 얻었다. 이상의 결과를 종합하여 볼 때, 새로운 사료작물인 케나프는 단위면적당 생초 및 건물수확량은 옥수수보다 높지만, 건물소화율 및 TDN 함량이 낮아 TDN 수량은 옥수수보다 낮은 것으로 나타났다. 결과적으로 홍마 300은 높은 수량성을 가지고 있지만 낮은 사료가치를 가지고 있는 것으로 나타났다.

쏘가리는 국내 주요 경제성 어종이며 방류 및 복원사업의 대상 어종 중 하나이다. 본 연구는 금강의 보 설치구간에서 쏘가리의 이동 특성 및 서식처 범위 등을 평가하기 위해 Radio telemetry를 이용하여 연구를 실시하였다. 연구 결과 산란기에 방류한 개체들의 경우 방류 즉시 상류로 10 km 이상 소상하였지만, 비 산란기에 방류한 개체들은 2개체를 제외한 모든 개체들이 방류 지점으로부터 400 m 이내에서 정착하였다 (Ss11, 3.2 km; Ss 15, 1.4 km). 산란기에 상류로 소상한 개체들이 정착한 지점의 서식처 특성은 기존에 알려진 쏘가리의 산란장 특성과 유사하게 나타났으며, 현재 퇴적이 진행되고 있는 상태였다. 쏘가리가 감지는 수변부에서 높은 비율로 나타났으며, 이는 수변부에 큰 돌이 많이 분포하는 것, 쏘가리가 주로 돌 틈에 숨어서 서식하는 특성과 관련이 있는 것으로 판단된다. 쏘가리의 개체 특성과 이동거리와의 상관관계 분석 결과 무게와 비대지수가 이동거리와 양의 상관관계를 보였으며 성별과 크기는 이동거리와 관련이 없는 것으로 나타났다. 일주기 이동범위 분석 결과 214.94 m2~3,257.19 m2로 나타났으며 주로 수변부에 국한되어 있는 것으로 확인되었다. 이와 같은 결과는 쏘가리 방류사업, 혹은 복원에 유용한 자료로 활용될 수 있을 것으로 판단된다.

The purpose of this study is to investigate the effects of two different types of vocabulary activities on Korean EFL learners’ vocabulary learning and perceptions. The participants of the study were 30 Korean middle school students in Seoul, and they were divided into two groups (typography and web-based authoring). The former employed the word meaning and spelling image association technique and the latter used a multimedia vocabulary authoring tool for 42 target words. The major findings of the study are as follows: (1) Both the typography and the web-based vocabulary authoring groups showed significant improvement on the posttest of vocabulary test, which indicated the equal effectiveness of the two vocabulary activities; (2) with respect to different English proficiency levels, the low-level group showed much higher improvement of the mean difference between pre and post tests than the higher group; and (3) the participants’ perceptions turned out to be more positive when they participated in creating English word spelling image than authoring multimedia vocabulary learning materials. The results suggest the beneficial effects of active student involvement in the vocabulary learning process. Pedagogical and practical suggestions are made on the effective teaching of English vocabulary in Korean classroom settings.

Smart Education strives to become one of the goals of current Korean education, and is a prominent core keyword. A major consideration for smart content for science education is creating self-directed, interesting content that considers user level and aptitude. The present paper will examine the development of interactive edutainment content, which meets the education goals of elementary and middle school curriculums. Among various scientific experiments found in both elementary and middle school curriculums, a physics experiment dealing with the law of levers was chosen for investigation. Through this prototype application that meets the standards of current elementary and middle school curriculums, new possibilities of scientific experiments may be uncovered for the smart education age.

Recently, the computer software has become an increasingly important share in the overall industry and many countries have been adapted an early SW education as their mandatory curriculum in school for children. Most of the prior SW education curriculums had been focused on how to learn a programming language to make a SW in a computer, but current SW education goal has been moved onto training the computational thinking to solve various problems with the computer, effectively. The paper exploits a game design activity as a good and fun tool to training such computational thinking for children. The proposed game design activity consists of a series of systematic curriculums to design a creative game in offline for the children who do not have any prior-knowledge of game. Participants first understand game elements such game title, synopsis, rules, game-play, which are indispensable to make a game. Then they try to understand what the fun is in the game and discuss with how to make such fun in the game. Finally, they have proposed a creative game design which is motivated by playing board-style games and iPad-games. With our assessment of the proposed activity, our game activity derives let the participants to computational thinking while creating the synopsis and game rules to define the game. It also revealed increased interest and understanding of computer software. We expect that the proposed game design activity could be an alternative to train computational thinking and a more holistic program to have increased interest and understanding of computer software for children.

The purpose of this study is to figure out current situation of safety education to improve safety awareness and practice in Korean school students. In order to do this, it is necessary to identify the current level of safety awareness and practice with the actual status of accident occurrence. Furthermore it is try to figure out the most influencing factors on the safety education for Korean middle and high school students. The 412 students were taken from a random sample. The samples were one class of 2nd grade students in five different middle schools and four different high schools in Seoul, Korea. The survey was conducted from 29 September 2010 through 15 October 2010. An additional samples for the questionnaires posted in web were collected. The 305 respondents from school students and 80 respondents from web survey were used to analyze for this study out of 800 respondents. SPSS was used to analyze the questionnaires. The overall safety-awareness score was relatively high at 4.56/5 for fire safety and 4.32/5 for traffic safety. Safety awareness was higher for girls than boys and also for high school students than middle school students. Safety education by parents at home gives a good impact on high safety practices. Safety awareness was improved by feeling of necessity for safety training. The safety prevention training provided during the class by teacher and home training by parents improved safety practice. The correct direction of safety education for younger students can be easier in future.

The present study sought to examine the continuity of the English textbooks of the elementary school 6th grade and the middle school 1st grade by analyzing the readability and vocabulary difficulty of their reading passages. It investigated the continuity between textbooks of the two grades and among chapters of each textbook. For the analysis, Flesch-Kincaid Grade Level Index was used to measure the readability of reading passages, whereas vocabulary difficulty was measured in terms of TTR (type-token ratio) and frequency by using VocabProfile. The results showed that the readability of middle school textbooks was one point higher than that of elementary school textbooks. Given that the readability index is based on the American school system, the increase in readability index between grades can be seen as large gap. In terms of vocabulary difficulty, the total amount of vocabulary in the middle school textbooks was three times as much as that of the elementary school textbooks. Second, readability index fluctuated across the chapters of each textbook, while the TTR was found to be higher in the former chapters than in the latter chapters in elementary school textbooks. All these could lead to learning difficulties for students. Pedagogical implications are discussed.

This study was analyzed to provide fundamental data on the relationship between fast food consumption behaviors and food-related lifestyle types. Data was collected from 268 middle students in the Incheon region through a self-administered questionnaire. A factor analysis extracted five comprising food-related lifestyle, which we named health seeking (factor 1), taste seeking (factor 2), easy seeking (factor 3), popularity seeking (factor 4) and safety seeking (factor 5). According to the results of the factor analysis, the food-related lifestyle showed that the average consumption was more than 2.95 and, 0.792 in Cronbach alpha coefficient. There were significant differences in the influence factor for the selection of fast food according to taste seeking and, popularity seeking types (p<0.05). Also, the easy seeking and safety seeking lifestyle types showed a significant differences for the reason the choosing criteria of fast food (p<0.05). Especially, the nutrition problem was of the highest importance for the health and safety seeking but an advertisement effect trend appealed more to the taste seeking, easy seeking and popularity seeking lifestyles. There were significant differences in fast food of intake frequency according to health seeking, easy seeking, popularity seeking and safety seeking types (p<0.05). A significant positive result of the internal characteristics of fast food consumption (p<0.05) was shown for the health seeking and safety seeking types. A significant positive result of the external characteristics of fast food consumption (p<0.05) was shown for the popularity seeking and safety seeking types.

This study investigates whether model dialogues in currently available middle school English textbooks present appropriate pragmatic input in the realization of speech acts or communicative functions with a focus on the authenticity of the textbook dialogues. To attain this purpose, a total of 18 textbooks were scrutinized in terms of communicative functions. The results showed that many of the textbook dialogues are devoid of adequate treatment of speech acts or communicative functions. The poor representation was evident in a wide array of communicative functions such as requesting/favor-asking, thanking, inviting, encouraging, complaining, responding to complaints, expressing sympathy, expressing surprise, refusing and responding to refusals. The misrepresented functions were largely due to the lack of sensitivity to situational constraints, interlocutor variables, and/or formality. Some cases were ascribed to pragmatic transfer from the native language. This study will contribute to the improvement of the currently available textbooks so that they can provide authentic speech act input.
