The purpose of the study was to investigate and develop a practical approach to integrating student-driven mathematical problems posing in mathematics instruction. A problem posing activity was performed during regular mathematics instruction. A total of 540 mathematical problems generated by students were recorded and analysed using systemic procedures and criteria. Of the problems, 81% were mathematically solvable problem and 18% were classified as error type problems. The Mathematically solvable problem were analysed and categorized according to the complexity level; 13% were of a high-level, 30% mid-level and 57% low-level. The error-type problem were classified as such within three categories: non-mathematical problem, statement or mathematically unsolvable problem. The error-type problem category was distributed variously according to the leaning theme and accomplishment level. The study has important implications in that it used systemic procedures and criteria to analyse problem generated by students and provided the way for integrating mathematical instruction and problem posing activity.

The purpose of this study is to examine the mediating role of self-efficacy and community consciousness in the relationship between volunteer activity experience and career decision level of university students majoring in social welfare. For this purpose, this study set up a research model based on the social cognitive career theory based on Keumboltz's social learning theory and Bandura's social cognitive theory. 260 students majoring in social welfare at three four-year universities in Chungcheongbuk-do were assigned and surveyed from September to October 2019. The multiple regression analysis was conducted to verify the correlation analysis and the mediating effect using SPSS 26.0. The results of the analysis showed that the volunteer activity experience of college students majoring in social welfare had a significant effect on the career decision level, and self-efficacy and community consciousness had a partial mediating effect on these relationships. Based on the results of this analysis, the intervention and follow-up studies for improving career decision level of university students majoring in social welfare were discussed.

This study aims to identify factors of life satisfaction of the adults with developmental disabilities, focusing on the comparison between young and old. Data are collected through in-depth interview of the adults with developmental disabilities as well as via workers proxy responses at the group home. Regression model analysis is conducted based on 387 cases. The result shows that the young adults with developmental disabilities are more likely to satisfied with life when they evaluate job performance of workers at the group home and when they are more actively involved in community activities. For the old adults with developmental disabilities, life satisfaction is positively associated with their evaluation of job performance of workers at the group home as in the young adults. In addition, life satisfaction of the old adults is higher when they feel less fatigue. It is also higher for those with more choices on residence and higher level of social activities. The findings reveals that enhancement of life satisfaction for the old adults with developmental disabilities dwelling at group home require supports and services for health and social activities different from other ages. It shares the general ideas that service efforts should be made for needs and desires of the recipients. The present study suggests to expand our research interests to include the disabled in danger of early aging, such as the persons with Down Syndrome and the persons with intellectual disability and cerebral palsy, and look into their particular needs.

민간에 의한 경찰활동의 역사는 뿌리가 깊다. 자신과 가족의 보호로부터 시작된 경찰활동은 시간이 지남에 따라 그 영역을 넓히면서 더욱 구체화 되었다. 경찰활동은 공공에 의한 경우와 개인적 차원의 활동으로 구분할 수 있다. 경찰활동을 police activity, police operation, policing이라고 하는데 공공 또는 정부 차원에서 이루어지는 경찰활동은 public police activity, 개인적 차원 혹은 민간 차원의 경찰활동을 private police activity라고도 한다. 인류 역사 이래 스스로를 지키기 위한 경찰활동이 있었으며 국가체제에서도 경찰국가로 불리던 시기가 있었다. 시간이 지남에 따라 경찰활동 영역에도 많은 변화가 있었는데 공경찰활동은 국가 또는 중앙정부, 혹은 지방정부의 변화와 맥락을 같이한다. 민간경찰활동 역시 경찰활동을 요구하는 개인 또는 기업 등의 변화에 따라 많은 변화가 있었다. 민간에 의한 경찰활동은 정부의 공경찰활동이 미치지 못하는 영역에서 요구되었으며 이는 자연스럽게 민간경찰활동의 성장으로 귀결되었다. 단순하게 개인과 재산, 시설 등을 경비하던 수준에서 벗어나 이제는 연관되지 않은 영역이 없을 정도의 발전을 하였으며 과학적이고 기술적으로 진보되고 발전되었다. 앞으로는 첨단 시설과 장비는 물론이고 각종 데이터베이스를 기반으로 하는 인공지능의 활용이 더욱 활발할 것으로 기대된다.

필자들은 제37회 교육자료전시회(1997)와 제38회 교육자료전시회(1998)에 작품을 출품하였다. 이들 교육자료전시회에 참가하게 된 동기는 다음과 같다. 입문기 아동의 수학교육은 학습내용에 대한 흥미를 가지도록 해야 하며 구체적인 조작활동을 통하여 수량에 대한 기초적인 개념과 원리, 그리고 법칙을 바르게 이해시켜 논리적 사고력을 기르도록 해야 한다. 그러나 대부분의 아동들을 목표수준에서 보면 만족스럽지 못하고, 시간이 지날수록 학습결손아가 늘고 있는 현실이다. 특히 오름길 학습지를 해결할 때는 우수한 아동에게도 조작활동을 시켜보면 뜻밖에 조작 활동을 제대로 못하고 당황하는 경우를 흔히 볼 수 있다. 이것은 개념 형성과 개인간의 차에 관심을 둔 지도가 이루어지지 않은 상태에서, 자기능력과 수준에 맞는 학습을 하지 못하고 다음 단계로 넘어가기 때문이라 판단하였다. 이에 필자들은 교과서에 예시한 활동이나 그림 자료들을 실제로 관찰하고 조작해 볼 수 있도록 구체적인 자료로 대체하여, 수학에서 요구하는 학습지도 원리에 적합하도록 하였다. 또 교실 수업에서 야기되는 개인차에 대한 학습지도상의 문제점을 해결하는 한편, 급우간 인간관계에 바탕을 둔 소그룹 협동 학습을 위한 자료로 수와 가감산의 원리를 쉽게 체득 시킬 수 있도록 하였다.

건설공사를 발주하는 공공기관은 대표이사 직속의 안전전담부서를 구성하고 있으나 순환보직 형태로 인력을 배치하여 안전보건에 관한 전문 지식이 부족하며, 여러 부서에서 안전관리 기준을 제정하거나 활동을하여 안전관리 체계에 혼선을 주고 있다. 또한 관리감독자들은 회사의 안전관리 기준을 제대로 인식하지 못하여 안전관리 활동이 원활하게 이루어지지 않고 있다. 건설공사를 발주하는 공공기관의 안전관리 활동수준을 향상하기 위해서는 안전관리 조직, 안전관리 체계, 위험성평가에 대한 개선의 노력이 필요하다.

We examined how public social expenditure and individual socio-demographic factors affect individual voluntary activities(volunteering, giving). Hierarchical linear model(HLM) was employed to a nested data set with 37,648 individual subjects and 16 local governments in Korea. HLM analyses yield an insignificant direct effect of public expenditure to volunteering and giving, while individual factors all have significant effects on them. Finally, this study discussed why public social expenditure factor does not have significant influence in this data, and suggested policy implications for promoting volunteering and giving.

In this study, the verbal interactions occurred during the CASE(Cognitive Acceleration through Science Education) activities in the middle school science class has been analyzed regarding with students cognitive level. The subjects were 24 students of 6 groups in a middle school in Korea. Verbal interactions within group discussions during CASE activities were audio-taped, transcribed, and analyzed. Also, classroom observation and interview with students were carried out. The results showed that the student with higher cognitive level tended to be a group leader. They had strong influences on the group discussions in each step of problem solving. Also, the higher cognitive level students were more active in metacognitive discussion and more often used scientific terms. When their group met difficulties in each stage of problem solving, such as perception of problem and designing experiment, the higher cognitive level students suggested some ideas to help their peers and gave them an explanation of how they worked. Low cognitive level students had difficulties in perception and solving the problem as compared with high cognitive students. It was common during activities for the low cognitive level students to fail to identify variables and to distinguish between dependent variables and independent variables. They failed to hold a number of variables at once. However, the metacognitive questions from their peers or teacher were helpful for them to construct the concept of controlling variables. If there is no student who has a high level of thinking in a group, it was necessary to intervene for teacher. A well judged questions from teacher created the cognitive conflict which causes the students to reconstruct their strategy for problem solving and reinforce the control of variables reasoning pattern. From the above results, it is concluded that students' cognitive levels are much related to the verbal interaction patterns. This suggests that teacher should consider individual student's cognitive level in organizing groups and intervene to facilitate the environment for metacognitive interaction.

In this study, volunteer experience(motive, durability, satisfaction, content) was set up as an independent variable, career maturity degree(determinacy, involvement, independence, tendency) was set up as a dependent variable, and the average difference and effect of the sub factors for each of them were reviewed. For this purpose, questionnaires were performed with 519 students at the middle schools and high schools in Busan. With 376 students having volunteer experiences among them, an analysis was done to find out the effect of volunteer experience on career maturity. The results of this study are as follows: First, whether having volunteer experience or not affected the career maturity among youths. That is the group with volunteer experience had higher level of interest, involvement and value in career and jobs than the group without them. Second, it showed that volunteer experience affected career maturity among youths. Specifically, career maturity was higher as their motive for volunteer activities was selfish, their satisfaction for volunteer activities was higher and they had more volunteer activities.

Aim: This study investigated the association between leisure activities and cognitive impairment in Korean community-dwelling older adults. Methods: Among participants of the 2017 National Survey of Older Koreans, 10,055 (male=4,277, female=5,778) were included in this cross-sectional study. To better identify the association between late-life cognition and leisure activities, individual leisure activities were categorized into 3 types including productive, consumptive, and unclassified activities. Multivariate logistic regression analysis was performed to assess the association between participation in leisure activities and cognitive impairment when controlling for possible covariates evidenced by previous studies. Results: Male participants were more likely to be cognitively impaired than female ones with significant differences in all the covariates. After controlling for confounding variables, involvement in productive leisure activities was found to be associated with cognitive function in both male and female groups, along with age, educational level, depressive symptoms, subjective hearing problems, and occupational status. Conclusion: Involvement in productive leisure activities might be associated with decreased risk of cognitive impairment in later life. Appropriate strategies to encourage older adults to participate in productive leisure activities should be established to help them maintain their cognitive function.
