The purpose of this study is to diagnose the problems of an elementary school care classroom in terms of facilities and physical environment and to suggest an improvement plan for building safer and more pleasant facilities and environment in further proceeding the policies of a whole-day care classroom. To this end, we analyzed the main contents of the domestic policies for elementary school care classes and the related spatial standards amongst the management plans of provincial education offices nationwide. In addition, we analyzed the relevant care facility standards of advanced countries such as the U.S., Australia, and Singapore and diagnosed the physical environmental level of Korean care classes in comparison to the international standards. Afterwards, we conducted a case study of elementary school care classes in order to examine the key issues with the environment of care classes, the causes of these issues and the user recognition and demand. The key results of this research are as follows. First, it is necessary to elaborate and refine the guidelines on elementary school care classrooms. Second, in order to provide high-quality elementary care services, it is important to have a combined classroom that can be operated at the level equivalent to or similar to a dedicated care classroom. Third, it is necessary to regularly check the facilities and environment of the elementary school care classroom.

This study examined different individual, family factors and classroom environment that affect children's perceived competency. For an analysis, achievement motivation, intrinsic locus of control and anxiety were included in individual variables. For family factors, parental support and marital conflict were examined. For classroom psycho-social environment, teacher support, peer relations, classroom involvement and teacher control were used. The sample consisted of 565 fifth and sixth grade children. Statistics and methods used for the data analysis were Cronbach's alpha, Factor analysis, frequency, percentage, t-test, Pearson's correlation, and Hierarchical Regression. Several major results were found from the analysis. First, boy's perceived academic competency was higher than girl's. And no sex difference was in children's social and athletic competency. Second, boy's and girl's perceived academic and social competency and boy's perceived athletic competency had a positive correlation with achievement motivation, intrinsic locus of control, parental support, teacher support, peer relations and classroom involvement. And girl's perceived athletic competency had a positive correlation with achievement motivation, intrinsic locus of control, parental support and peer relations. But boy's and girl's perceived academic and social competency and boy's perceived athletic competency had a negative correlation with anxiety and parental marital conflict.

School lunch programs at middle schools have increased in quantity. However, the quality of them is in fact not enough to reach the satisfactory standard, especially in the aspect of environment of school meals. It is true that there seems to be little attention to the environment. In this study, degree of satisfaction about school lunch program was surveyed for students in one middle school. Focus of survey was sanitary condition about the dining room and classroom where they have lunch. First, in order to investigate the degree of satisfaction about their dining place, questionnaire was sent out to the students at one middle school in Seoul. Questionnaire was made with reference to previous research. Second, for the study on environmental sanitation, dropping bacteria (general bacteria) is measured in three parts of dining place (entrance, serving table, dining table). Petriplate film was exposed to the responsible places for 15 minutes and then cultivated at the temperature of $32^{\circ}C$ for 48 hours before counting the number of bacteria formed. For the statistical analysis, SPSS 12.0 was used. The results of the study show that students had more satisfaction in dining room service than in classroom service. Important factors for the meal program such as "taste of food", "amount of food per student", "state of keeping warm", "appearance of food", "diversity of menu", and "kindliness of feeding staff" had more points in dining room than in classroom. For the environmental and sanitary aspect, the result of dropping bacteria (general bacteria) in dining room and classroom showed that table (5.00) and fooddistribution corner (8.67) of dining room were cleaner than those of classroom (P < 0.05). Making a good environment for school feeding will have a positive effect on the improvement of satisfaction and sanitation of school feeding. There should be expansion of dining room service for the students.

One challenge with teaching practical programming classes is the standardization of development tools on student computers. This is particularly true when a complicated setup process is required before beginning to code, or in remote classes, such as those necessitated by the COVID-19 pandemic, where the instructor cannot provide individual troubleshooting assistance. In such cases, students who encounter problems during the setup process may give up on the class altogether before even beginning to code. Therefore, this paper recommends using GitHub Codespaces as a tool for implementing standardized student development environments from day one. Codespaces provides Docker containers that an instructor can configure in such a way as to enable students to practice installing various coding tools within a controlled space, while also providing a language-specific, fully optimized development environment. In addition, Codespaces may be used more effectively in collaboration with GitHub Classroom, which helps instructors manage both the starter code and coding environment in which students work. In this paper, we compare two semesters of university Node.JS programming classes that utilized different development environments: one localized on student computers, the other containerized in Codespaces online. Then, we discuss how GitHub Codespaces and GitHub Classroom can be used to increase the effectiveness of practical programming classes while also increasing student engagement and programming confidence in class.
