This study aims to analyze the impacts on self-regulated learning (SRL) and problem-solving (PS) competencies rather than learning achievement through the use of digital textbooks in the SMART learning environment. To achieve the objective, $3^{rd}$ and $4^{th}$ grade elementary and $1^{st}$ year middle school students were selected from 29 schools where the digital textbooks were utilized in the subjects of science in pilot schools in 2014. In this, One-Group Pretest-Posttest Designs were applied as a research method to analyze SRL and PS competencies. Additionally, the effect size of Cohen's d was presented in order to display the practical significance. The results showed the positive impacts on SRL and PS competencies, in spite of a small effect size of about 0.2 through the use of digital textbooks. ANCOVA was conducted to determine the difference in the impacts according to demographic variables. The results demonstrated that the difference in the impacts on both SRL and PS were statistically significant according to the grade and level. For SRL, both the elementary grade 4 and middle school students showed more significant differences than elementary grade 3. Moreover, for PS, the elementary grade 4 students showed the most significant difference.

In the era of globalization, a significant number of young students go abroad to learn English. By reviewing the trends and characteristics of this phenomenon, this study will focus on the adjustment of young Korean students in Australia. During June and July 2002, two questionnaire surveys were conducted for year 7 to year 12 Korean students at the Saturday Schools in Sydney Australia and for the youth group at the Sydney Catholic Church. More data was collected from interviews with 31 Korean teachers at the Saturday Schools and Linfield Korean school, as well as observations of the students in the Sydney area. The study divided the students into four groups: 1) Korean immigrant students, whose parents immigrated to Australia; 2) Individual Korean students who went alone to Australia to study; 3) Students whom live in Australia with one parent (usually their mother), whilst the other parent (usually their father) who provides financial support by working in Korea; and 4) students who accompanied their parents whom were dispatched for temporary employment or study in Australia. Moreover the study focused on the following; their academic performance, school activities, motivation, social relations, and their overall satisfaction with their studies and their stay in Australia. The findings indicated that the temporary overseas Korean students, especially those that are not with their parents do not adjust as well as the Korean immigrant students. The students who were not accompanied by their parents to Australia had the most difficulties adjusting as they were more vulnerable and fell behind with their studies. Therefore, the results support the concerns of Korean teachers in Australia about parents sending young students alone abroad.

Background/Aim: There is little data on whether plastic stents with a larger diameter are patent for longer than small stents in patients with bile duct cancer. The aim of this study was to compare the stent survival between 7-French (Fr) and 10-Fr plastic stents and evaluate the factors affecting stent survival. Methods: Patients with biliary obstruction due to biliary tract cancer were enrolled at Yonsei University Wonju College of Medicine from January 2010 to October 2014. Results: A total of 215 patients (7-Fr:10-Fr = 89:126 patients) were retrospectively enrolled. The primary tumor sites were common bile duct (n = 111), hilar (n = 45), and ampulla of Vater (n = 59). Rates of stent migration and stent obstruction were not different between the two groups. The median duration of stent survival was 3.3 months in the 7-Fr group and 5.9 months in the 10-Fr group (p = 0.543). The diameter of the stent did not have an effect on stent survival (hazard ratio 1.11, 95% confidence interval 0.71-1.73, p = 0.649). Conclusions: 7-Fr and 10-Fr stents have similar rates of stent migration and stent obstruction. The stent survival of 7-Fr was not inferior to 10-Fr stents in the management of biliary tract cancer.

Background & Objectives: This study aimed to examine the relationship between subjective health perception and health behaviors among adolescents, utilizing raw data from the 8th Korea National Health and Nutrition Examination Survey (2019-2021) while distinguishing between genders. Methods: The study employed data from the 8th Korea National Health and Nutrition Examination Survey (2019-2020), recruiting students from 1st to 3rd grades in middle and high schools nationwide. Through population stratification, sample distribution, and sampling stages, a final sample of 1,065 adolescents aged 12 to 18 years was selected. The collected data were analyzed using SPSS 28.0 (IBM Corp., Armonk, NY, USA) at a significance level of .05. Results: Regarding the general characteristics of the subjects, no statistically significant differences were observed among male students based on school, family structure, and income. However, among female students, a significant difference in subjective health perception was noted, with higher perception among high school students compared to middle school students (p=.001). Significant differences in health behaviors were identified based on family structure for male adolescents, where those living with both parents exhibited more health-promoting behaviors than single-parent adolescents (p=.011). However, no significant difference was observed among female adolescents. In terms of health behaviors related to gender, regular exercise was found to significantly impact subjective health perception in male adolescents (p=.013), while breakfast habits were identified as significant influencers for female adolescents (p<.001). Conclusions: This study revealed gender differences in subjective health perception and health behaviors among adolescents. Based on these findings, there is a perceived need for the development of health promotion programs tailored to the unique needs of male and female adolescents.

The study aims to extract the framework of sub-factors of spatial sense, to develop test instruments based on the framework to investigate the actual spatial sense ability of fourth to sixth graders in elementary school and to analyze the results. According to the framework of sub-factors of spatial sense of the study, spatial sense has two factors of spatial visualization and spatial orientation. Spatial visualization is divided into mental rotation, mental transformation and figure-ground perception while spatial orientation is categorized into direction sense, distance sense, and location sense. Based on the framework, the test instrument for spatial sense ability was developed and the test was conducted to 430 fourth to sixth students in five elementary schools in capital areas. The following conclusions were drawn from the results obtained in the study. Firstly, the higher school year gets, the more spatial sense grows. However, spatial visualization is developed much more than spatial orientation and their order is reversed with higher graders. Secondly, the most insufficient abilities among fourth to sixth elementary school students' spatial sense were mental transformation of spatial visualization and location sense of spatial orientation. Thirdly, the reasons of differences in sub-factors of spatial sense and graders seem to be from effects of students' learning experiences of spatial sense of mathematics curriculum and the complexities of test items.

Researchers in science education have recently focused on service learning as an important educational approach to address environmental challenges including climate change. However, there are a limited number of studies focused on service learning in science education in Korea. In this study, based on existing related literature, the theoretical background of service learning is introduced and a conceptual framework that can be applied in the science education environment in Korea as a new approach to address environmental challenges is proposed. Given this, 112 relevant academic documents collected by searching a global database were analyzed. As a result, the theoretical background of service learning rooted in Dewey's experiential learning is introduced. Specifically, service learning is defined as a form of experiential learning that supports students in helping communities with structured services related to learning content, while at the same time fostering their in-depth understanding of content and engaging in civic and social responsibility as members of their community. In addition, a conceptual framework for service learning to address environmental challenges that can be applied to the science education environment in Korea is proposed. The proposed framework classifies the members of service learning into schools, students, and communities, and presents knowledge, experience, and learning through critical reflection as its core elements. It is important to actively implement service learning in science education to address various environmental challenges including climate change, biodiversity loss, air pollution, and deforestation, as just a few pressing challenges. Therefore, based on the proposed conceptual framework for service learning, studies that apply and verify diverse forms of educational approaches to addressing environmental challenges in local communities at school sites are needed.

The psychological problems following the experiences of school-violence could be more important than the physical problems. Victims could suffer from fear, depression, anger, lowered self-esteem, suicidal thought, and personality changes. To study the risk factors for school violence and the psychiatric problems after the experiences to school-violence provide us important informations to prevent and solve the problems of school violence. We examined clinical characteristics and psychosocial backgrounds of 13 adolescents who visited the psychiatric clinic after exposures to school violence from September, 1996 to May, 1997. The clinical data included intensity, motivations, durations, and methods of violence, psychiatric symptoms following exposure, findings of psychological test, and treatment course. The socioeconomic data included developmental characteristics of subjects, family characteristics, school life, and peer relationships. Of the 13 adolescents who experienced exposure to violence, 8 have experienced chronic psychiatric disturbances, 5 experienced transient psychiatric symptoms such as anxiety, depression, suicidal attempt who eventually returned to home and school life. Of the 8 adolescents who experienced chronic psychiatric disturbances, 4 experienced PTSD and depression lasting 3-6 months more, otherwise 4 showed converted features, such as aggressive behavioral disorder or perpetrator by strong compensatory effects after psychological shock. The subjects who have experienced chronic psychiatric disturbance have clinical characteristics such as physical or emotional abuse, physical illness or handicap, defects of ego functionings, and lack of family support. In summary, victims by school-violence manifested serious psychiatric disturbances, and they had clinically significant risk factors and some of them became perpetrators of school-violence.

The purpose of this study is to examine the mediating effects of resilience in the relationship between parent support and career decision level of specialization technical high school students and to find out ways to improve the level of desirable career guidance and counseling. The research questions are as follows: First, what is the level of parent support, career decision level, and resilience of special technical high school students? Second, what is the relationship between parent support, career decision level and resilience of high school students? Third, the resilience of resilience plays a mediating role in the relationship between parent support and career decision level of special technical high school students. In order to achieve the purpose of the study, the theoretical background related to parent support, career decision level, and resilience of special technical high school students was investigated and the test tool was produced. The results of the study are as follows. Parental support, career decision level, and resilience were highly correlated. There was a significant correlation between parent support and career decision level, resilience and career decision level, and emotional support and verbal encouragement were more than 50% of the career decision level. In terms of mediating effect, the effect of parent support on career decision level was found to be partially mediated by overall resilience and sub - factors such as control, positive, and sociality. Therefore, in order to improve the quality of career guidance counseling, a program linked to the school and the home should be conducted considering both domestic factors and internal factors.
