This study investigated the clothing easiness of movement when wearing casual Hanbok(Saenghwal Hanbok), as a high school student uniform, and produced some recommendations for improving the Hanbok. Casual summer-uniform Hanbok produced from different types of materials were produced for this study. They were P/R, P100, P/C, and P/R/S for the blouses, with P/W, P100, P/R, and P/W/F for the skirts. Their clothing easiness of movement were then tested at $25{\pm}1^{\circ}C$ and $50{\pm}10%$ R. H. The results were as follows: The easiness of movement for casual Hanbok was marked as $3.7l({\pm}1.03)$ on average which is higher than those of other garments, so it can be presumed that the easiness of movement for the tested clothes was quite good. The easiness of movement was lower, however, when students had their arms up front, right arms upright, arms crossed on the cheats, and bent forward whereas they were more comfortable when standing straight and sitting on a chair at 90 degrees. In terms of easiness of movement, the following ranking was revealed: waist, bust, shoulder, back, armhole, and upper arm. The easiness of movement for casual Hanbok skirts was quite good, and on average marked around $4.26({\pm}.77)$. Standing straight was the most comfortable position, when they bend forward 45 degree and 90 degree were the most uncomfortable positions. The buttocks area was also more comfortable than the waist area for casual Hanbok skirts.

이 글은 2010년대에 이루어진 1990년대와 2010년대의 학생운동 경험 구술을 대상으로, 각 구술에서 '우리'가 그려지는 양상의 차이와 그 차이를 만들어낸 배경으로 2010년대의 조건이 만들어낸 일상적 경험의 누적을 주목한다. 2010년대에 채록된 1990년대 학생운동 경험에 관한 구술에서 두드러지는 것은 당시의 학생운동 문화에 대한 거리감이다. 1990년대에 대학 생활을 경험한 구술자들의 말 속에서 당시 대학의 학생운동 문화는 사적 관계를 타고 이루어지며 굳이 설명할 필요도 없이 '자연스러운' 것으로 여겨졌는데, 동시에 그 '자연스러움'은 그것이 구술되고 있는 2010년대의 맥락에서는 '부자연'스럽거나 '이상한' 것으로 이야기되며 현재의 구술자와는 일정한 거리감을 지닌 경험으로 의미화되었다. 이러한 양상은 90년대의 경험이 2010년대에 구술되고 있는 조건과 결부되어있다. 구술자들에게 과거의 경험을 구술하는 '현재'는 '촛불' 이후 이자 '강남역' 이후로 설명되었고, 그 이전과는 질적으로 다른 세계인 듯 묘사되며 자신의 과거 경험으로부터 비판적 거리를 발생케 한 계기로서 위치했다. 균질한 '우리'를 의심케 하는 이 질적 변화는 무엇보다 한국사회에서 젠더 이슈가 가장 커다란 화두였던 2010년대 중반 이후를 살며 새로이 체득된 젠더적 감각에 기반을 둔다. 2010년대의 사회운동 경험에 관한 구술에서는 '우리'의 구성이 더 이상 어떤 공통성을 공유하는 이들의 공동체가 아니라 수많은 다름에도 불구하고 결집한 개인들과 같이 이해된다. 그리하여 2010년대의 학생운동 구술은 이런 것을 이미 일상의 감각으로 체화한 이들의 경험이 드러난다. 이들이 구성한 '우리'는 사적 관계와는 무관하거나 무관해야 하는 것이었고, 동질성이 가장 두드러진 집단으로 여겨지지도 않았으며, 그래서 시위 당시와 그 자리 바깥에서까지의 '나'를 설명할 수 있는 무엇도 아니었다. 관련 경험이 내내 조심스러운 태도로 구술되었던 것도 그런 맥락에서였다. 이는 결국 '학생운동', 나아가 사회운동과 '우리'로 결집하는 감각을 새로이 질문하고 이해해야 할 필요성을 제기한다. 운동의 주체가 과연 '누구'인가를 묻는 일의 효용을 질문한다. 곧, 운동에서 고정된 '우리'라는 정체성을 규정하는 일의 필요성과 의미를 질문한다. 그리하여, 어떤 고정된 위치나 좌표가 과연 누군가의 입장을 대변할 수 있는 것인가를 질문한다.

Background: Instrument players are exposed to occupational musculoskeletal symptoms due to constant movement and strain to meet the needs of their audience. This can cause dissonance between the player and the instrument and can cause medical problems in the musculoskeletal system such as pain, tendinitis, muscle spasms, and joint hyperextension from overuse of body parts. Objective: The purpose of this study is to comparatively analyze the characteristics and occurrence of musculoskeletal symptoms in professional and student players, and to find out the awareness of the need for health care professionals and special exercise programs for orchestra players. Methods: The subjects were professional orchestral musicians 191 from the three symphony orchestras and music students 209 from the four universities volunteered to participate in this study; 393 subjects (98.25%) completed the questionnaire. symptom prevalence and related factors of playing-related musculoskeletal disorders (PRMDs) were surveyed with a self-administered questionnaire. Standardized Nordic Questionnaire was complemented by adding a visual-among scale and used to diagnose PRMD. Results: High prevalence of musculoskeletal complaints in both professional musicians (85.30%) and student musicians (82.30%). Professional musicians and student musicians also suffered the highest problem in shoulder and neck complaints. Significant differences were found between groups that recognized of necessity for specialized health professionals, professional organizations, and special programs for musicians. Conclusions: Professional musicians and student musicians, like orchestra players, are already exposed to overuse syndrome. However, student musicians lack awareness of the risk of injury compared to orchestra players. We suggest that an appropriate treatment management program for the prevention and early treatment of musculoskeletal system damage should be provided to performers at an early stage.

This study analyzed the difficulties of middle school students in computer simulation of the law of large numbers through eye movement analysis. Some students did not attend to the simulation results and could not make meaningful inferences. It is observed that students keep the existing concept even though they observe the simulation results which are inconsistent with the misconceptions they have. Since probabilistic intuition influence student's thinking very strongly, it is necessary to design a task that allows students to clearly recognize the difference between their erroneous intuitions and simulation results. In addition, we could confirm through eye movements analysis that students could not make meaningful observations and inferences if too much reasoning was needed even though the simulation included a rich context. It is necessary to use visual representations such as graphs to provide immediate feedback to students, to encourage students to attend to the results in a certain intentional way to discover the underlying mathematical structure rather than simply presenting experimental data. Some students focused their attention on the visually salient feature of the experimental results and have made incorrect conclusion. The simulation should be designed so that the patterns of the experimental results that the student must discover are not visually distorted and allow the students to perform a sufficient number of simulations. Based on the results of this study, we suggested that cumulative relative frequency graph showing multiple results at the same time, and the term 'generally tends to get closer' should be used in learning of the law of large numbers. In addition, it was confirmed that eye-tracking method is a useful tool for analyzing interaction in technology-based probabilistic learning.

The purpose of this study is to investigate the conceptions about altitude of the Sun of elementary students according to differences by the spatial ability. In this study through the qualitative analysis, 4 students who were similar understanding levels of concepts to altitude of the Sun and differences by the spatial ability were selected out of 75 in 6th grade elementary located in Sunchang, Jellabuk-do Province. 4 students for the qualitative analysis were selected by the test instrument of spatial ability and altitude of the Sun. The results of study was students with higher spatial ability were higher understanding levels of concepts to altitude of the Sun. However, both of student with higher and lower spatial ability showed a false concept to the expanded concepts into outer space like a cause of seasonal change, change of altitude of the Sun by latitude unlike the intution. Students with lower spatial ability didn't form the scientific concepts, not only a cause of seasonal change and change of altitude of the Sun but also difference of energy density by altitude of the Sun. A student of two with lower spatial ability has been impediment strongly to form the scientific concept by the false concepts to the distance. The findings were as follows; Learning to altitude of the Sun regardless of the difference of spatial ability should be learned to interact to the intution, celestial movement and model experiment. To students with lower spatial ability should be developed teaching methods to understand the relation between the Sun and celestial movement.

Reports on population movement(2000-2030) by the National Statistical Office show that the number of elementary school age population will be decreased by 1.4million from 2005 to 2020. It will effect both school size and the policies for school facilities, which have focused on downsizing class as the high standard of OECD nations. As the unfolding evidence is emerging that a number of schools and classes will be emptied out by 2030. This study aims at developing a objective and scientific device for estimate the number of students at future and evaluating the validity of school establishment. In doing so, it explores the relationship between the changing factors and the number of students. It proposes four factors such as the changes of population, the fertility rate, the number of apartment occupant and movement of population. As the result of the statistic analysis on the correlation coefficient, it finds out that the change of apartment occupant has a close correlation with the change in the number of student and has a deep effect on the establishment of school. Finally, it shows the construction of school according to urban developments during 1999-2008 in Incheon Metro-City. This study would help the authorities to expect the future number of student and to restrict overbuilding of surplus classes, finally the reasonable expenditure for school facilities.

To study the correlation with increasing body fat mass for the Standard Guideline for Korean Dietary Life, a nationwide, cross-sectional survey was performed with 178 male college students in december 2005. Among the student subjects, 76 were analyzed for body protein mass, body mineral mass, body fat mass, percent body fat, waist-hip ratio(WHR), body mass index(BMI) and obesity degree using Inbody 3.0(Biospace Co, Seoul, Korea). Body protein mass was at a high level of 92.1%, body mineral mass was at a low level of 94.7%. Body fat mass was at a high level of 28.9%, percent body fat was at a high level of 37.3%, WHR was at a high level of 31.6%, and obesity degree was at a high level of 38.2%, BMI was at a high level of 24.3% and BMR was observed at a high level of 41.8%. WHR was correlated with '7. Prepare food proper amount sanitarily.' and obesity degree, while BMl was were correlated with '4. Increase movement and eat proper amount.' positively. BMR was correlated with '6. Enjoy 3 meal a day regularly.' ArmCircle was correlated with '4. Increase movement and eat proper amount.' and fitness score was corrected with '4. Increase movement and eat proper amount', and '8. Enjoy Korean rice food style.' positively. Body protein mass and body mineral mass were negatively correlated with fruit, ArmCircle was positively correlated with fish, obesity degree was positively correlated with soup and BMI and ArmCircle were positively correlated with sweet. '8. Enjoy Korean rice food style.' was negatively significantly correlated with overweight, over percentage body fat, obesity degree > 120 and BMI. Male students were not practicing the Standard Guideline for Korean Dietary Life well with an average score of 37.7%. However, male students who are within the normal range of body composition analysis value have to notice that over range of weight, protein, percentage body fat, WHI and obesity degree was observed above average score of 30%.

Objective: This study aimed to evaluate the effect of an intentionally created socket on bone remodeling with orthodontic tooth movement in rabbits. Methods: Eighteen male rabbits weighing 3.8 - 4.25 kg were used. An 8-mm deep and 2-mm wide socket was drilled in the bone 1 mm mesial to the right mandibular first premolar. The left first premolar was extracted to serve as an extraction socket. A traction force of 100 cN was applied to the right first premolar and left second premolar. Sections were obtained at the middle third of the moving tooth for both the drilled and extraction sockets and evaluated with hematoxylin and eosin staining and immunohistochemical analyses. The amount of tooth movement and tartrate-resistant acid phosphatase (TRAP)-positive cell count were compared between the 2 groups using the Mann-Whitney U test. Results: At week 2, the distance of tooth movement was significantly higher in the intentional socket group (p < 0.05) than in the extraction socket group. The number of TRAP-positive cells decreased in week 2 but increased in week 3 (p < 0.05). However, there were no significant differences between the groups. Furthermore, results of transforming growth factor (TGF)-${\beta}$ staining revealed no significant differences. Conclusions: The intentional socket group showed greater distance of tooth movement than did the extraction socket group at week 2. Osteoclast counts and results of immunohistochemical analyses suggested elevated bone remodeling in both the groups. Thus, osteotomy may be an effective modality for enhancing tooth movement in orthodontic treatment.
