Since the introduction of the new Variation Type school, few studies have focused on students' adaptation to the changes in their learning environments at school. This paper is based on the Stage-Environment Fit theory, which asserts that a successful school life(in terms of motivation to learn) is ensured only when the school environment meets the social and emotional needs of students. Focusing on the third-grade student's adaptation to a new Variation Type school during their middle school period, the following conclusions were drawn. First, the transition to a new Variation Type school during middle school is much more difficult than adjusting to a new Variatio Type school upon admission to middle school. Second, this difficulty in adaptation is caused by socio-emotional dissatisfaction in adolescent students, for whom deconstruction of previous friendships can hinder motivation to learn. Third, third-grade students who experienced stress due to spatial changes tended to have a negative attitude towards the new Variation Type itself as they feel more tired from failing to use the space properly. Fourth, to transition successfully to a new Variation Type school, socio-emotional problems must be solved through the reduction of scale of the homebase, and the provision of various choices increasing the number of homebase.

Purpose: The purpose of this study was to compare the clinical and radiographic features of temporomandibular joint (TMJ) osteoarthritis (OA) between adolescents and middle-old aged patients. Methods: The subjects were chosen among the patients who presented to the Department of Oral Medicine of Pusan National University Hospital and were diagnosed with TMJ OA by clinical exam, X-ray and cone-beam computed tomography (CBCT) from 2010 to 2011. We investigated 93 adolescent patients (12-19 years) and 53 middle-old aged (>45 years) patients who observed the erosive bony changes in TMJ. CBCT scans were retaken at intervals at an average of 8 months. Results: The adolescent patients showed unilateral degenerative changes more often, and the middle-old aged patients showed degenerative changes more frequently on both sides. The transition of bone changes to the improved group occurred most commonly in both the adolescent and middle-old aged patients. The adolescent patients were more likely to improve than middle-old aged patients. In the adolescent patients, loss of erosion and subjective symptoms occurred in shorter periods than in the middle-old aged patients. In the adolescent patients, the transition of erosion was distributed into proliferative, normal, and shortening in order. In the middle-old aged patients, the transition of erosion was distributed into shortening, proliferative, and normal in order. Conclusions: The clinical and radiographic features of TMJ OA are a significantly different between the adolescent and middle-old aged patients. Moreover, the difference by age of the adaptive and regenerative capacity of TMJ affects the prognosis of TMJ OA and adolescent patients have a better prognosis after treatment.

Using a person-centered approach, the current study investigated latent profiles for the emotional and behavioral problems of students in sixth-grade in elementary school and second grade of middle school. The aim was to explore latent transition patterns and verify the factors affecting the transitions. The participants were 1,937 adolescents who responded to the 3^rd year (6^th grade of elementary school; Time 1), 4^th year (1^st grade of middle school), and 5^th year (2^nd grade of middle school; Time 2) of the Korean Children Youth Panel Study. Latent profile and latent transition analyses were performed. The results were as follows: first, the latent profile of emotional and behavioral problems changed from Time 1 to Time 2. The latent groups at Time 1 were classified into low, moderate, high, and externalizing-dominant, whereas at Time 2, five groups were identified: low, moderate, high, externalizing-dominant, and withdrawal-dominant. Second, transition analyses revealed that although 22.3-57.0% of latent groups remained unchanged, there were significant changes over time between groups, as a new group ('withdrawal-dominant') emerged in Time 2. Third, different factors influenced the latent profile transition of emotional and behavioral problems depending on the transition pattern. Higher levels of self-esteem, better relationships with peers and teachers, and lower levels of parental inconsistency meant emotional and behavioral problems had not worsened at Time 2. The results suggest that early interventions are needed during the transition from childhood to early adolescence.

The study aimed to qualitatively examine middle school students' engagement in distance instruction during the COVID-19 pandemic. The participants comprised 119 students from a girls' middle school in Seoul, South Korea. To gain an in-depth understanding of the students' experiences, we collected their reflective journals, which included structured items about their learning engagement at three timepoints in 2020: April, July, and December. The following are the results: 10 themes and 18 concepts were derived, and they were integrated into causal conditions (sudden transition due to COVID-19), contextual condition (technology readiness, school education context), central phenomena (high level of behavioral engagement, low emotional engagement), interventional conditions (recognizing the potential of online learning, situational awareness about COVID-19 and online learning), action/interaction phenomena (development and use of self-regulated learning strategies), and consequences (changes in practices and perception towards online learning). Based on the findings, engagement patterns of the participants were classified into five types: proactive, conservative, receptive, reactive, passive learners. The present study demonstrated important findings that are essential for the improvement and development of engaging online learning strategies in the future.

The purpose of this study was to identify transition conditions, health behavior and indicators of healthy transitions among middle-aged women based on Schumacher & Meleis(1994) transition model for developing intervention program for their health promotion. A convenience sample of 221 women aged 40-60 was obtained in Jung-Gu, Seoul and they were asked to complete the questionnaires, which consisted of modified health-promoting lifestyle profile(HPLP), knowledge of menopause, physical well-being, emotional well-being, modified women's role integration protocol (WRIP), Beck's Depression Inventory(BDI), and indicators of healthy transition with subcategories such as subjective well-being, role mastery and well-being of interrelationship. The results were as follows: 1. Women had a mean age of 47.53 years. More than half(53.39%) of the women had jobs and 88.69 % had their spouses, Of 221 women, 51.13 % were premenopausal, 19.91% were perimenopausal, and 28.96% were postmenopausal. 2. Women scored lower on health responsibility and exercise than on self actualization, nutrition and interpersonal support among subcategories of health behavior measured the modified HPLP. Only 11.98% of respondents had breast-self examination and 42.66% had pap smear for screening cancer. 3. In transition conditions, women had poor knowledge about menopause and median level of physical well-being, emotional well-being and stress. 15.45% of the women had clinical depression. 4. As for the outcome index of the transition model, the mean of indicators of healthy transition was 3.69(possible range 1-5). 5. The levels of education and economic and the menstrual status were significantly related to physical well-being, depression and stress in the categories of transition conditions. The total score of health behavior correlated negatively with depression. The total score of indicators of healthy transition correlated with physical well-being, emotional well-being, stress, and depression in the categories of transition conditions. In conclusion, these findings suggested a profile of fragile middle-aged women and contributed to developing the community-based intervention program for health promotion.

This paper analysed gifted middle students' conception of the definitions of point and line and the uses of definitions in proving. The findings of this paper suggest that the concept of mathematical definitions is very unnatural to students, therefore teachers and textbooks need to explain explicitly the characteristics of mathematical definitions which are different from dictionary definitions using common sense. Also introducing undefined terms in middle school geometry would give students a critical chance to deal with the transition from dictionary definitions to mathematical definitions.

교과 내용 흥미도는 교육과정 개정 및 교과서 개발에 도움을 주는 방식으로 학생보다는 교사 측면에서 연구되어왔다. 본 연구에서는 중·고 전환기에 해당하는 고등학교 1학년 학생들에게 생활 연계 차원에서 매우 의미 있는 가정과 내용을 중심으로 중학교에서 배운 내용과 고등학교에서 배운 내용에 대한 학생들의 흥미도를 알아보기 위해 고등학교 1학년 학생 227명을 대상으로 중학교 가정과 내용 17문항, 고등학교 가정과 내용 10문항으로 구성된 흥미도 검사 도구를 활용하여 자료를 수집하였다. 이를 성별 및 성취 수준별로 흥미도 차이를 분석하였다. 연구 결과에 따르면 중·고 전환기인 고등학교 1학년 학생들의 경우 청소년 발달 등 자신에 관한 관심은 가족의 요구나 가정생활에 관한 관심에 비해 상대적으로 높은 것으로 나타났다. 성별에 따른 차이는 나타나지 않았으나, 성취 수준에 따라 내용 흥미도에 차이가 나타났다. 이는 학습자의 발달과 학교급 전환기라는 학습자의 상황, 대학 입시 등 다양한 변인들을 함께 고려하여 내용 흥미도를 해석해야 함을 의미한다. 본 연구의 결과는 향후 교육과정 개정, 교과서 개발 및 교과 수업에서 고려해야 할 시사점을 제공하며, 학습자 중심 관점을 토대로 교과 내용에 대한 학습자의 흥미 정도를 세심하게 분석하고 활용해야 할 것이다.

Algebra deals with so general properties about number system that it is called as 'generalized arithmetic'. Observing students' activities in algebra classes, however, we can discover that recognition of the generality in algebraic proofs is not so easy. One of these difficulties seems to be caused by variables which play an important role in algebraic proofs. Many studies show that students have experienced some difficulties in recognizing the meaning and the role of variables in algebraic proofs. For example, the confusion between 2m+2n=2(m+n) and 2n+2n=4n means that students misunderstand independent/dependent variation of variables. This misunderstanding naturally has effects on understanding of the meaning of proofs. Furthermore, students also have a difficulty in making a transition from algebraic proof to numerical cases which have the same structure as the proof. This study investigates whether middle school students can recognize dependent generality and make a transition from proofs to numerical cases. The result shows that the participants of this study have a difficulty in both of them. Based on the result, this study also includes didactical implications for teaching the generality of algebraic proofs.

This study examined the transition of costume in middle and high school girls after the abolition of school-uniform. Fashion photographs of $\ulcorner$Junior$\lrcorner$a Korean magazine for girls were used for the investigation. Skirts used mainly were changed in order of pleat tight flare and tight skirt And skirt length was changed in order of knee midi knee and mini. Slim baggy and straight pants together showed high frequency but after 1992 straight pants were used mainly. And pants of ankle length was prevalent. In jacket Hip line natural waist and H-line silhouette dominated. Silhouette of one-piece dress was changed in order or X line H line and A line. Semi fit and natural waist were prevalent. And length was changed in order of midi knee and mini. The coat of H line Loose semi fit and Knee length was the most frequently appeared style. Waist line of coat was changed in order of natural low no natural waist. In skirt blue white black and black were mainly in spring summer fall and winter respectively. In pants blue was used mainly regardless of the season, In jacket blue in spring and black in other seasons were used. In one-piece derss blue in spring red in summer black in fall and winter were used mainly. Black coat was used mainly. Therefore blue was the most frequently used color by middle and high school girls.
