Productive struggle is a student's persevering effort to understand mathematical concepts and solve challenging problems that are not easily solved, but the problem can lead to curiosity. Productive struggle is a key component of students' learning mathematics with a conceptual understanding, and supporting it in learning mathematics is one of the most effective mathematics teaching practices. In comparison to research on students' productive struggles, there is little research on preservice mathematics teachers' productive struggles. Thus, this study focused on the productive struggles that preservice mathematics teachers face in solving a non-routine mathematics problem. Polya's four-step problem-solving process was used to analyze the collected data. Examples of preservice teachers' productive struggles were analyzed in terms of each stage of the problem-solving process. The analysis showed that limited prior knowledge of the preservice teachers caused productive struggle in the stages of understanding, planning, and carrying out, and it had a significant influence on the problem-solving process overall. Moreover, preservice teachers' experiences of the pleasure of learning by going through productive struggle in solving problems encouraged them to support the use of productive struggle for effective mathematics learning for students, in the future. Therefore, the study's results are expected to help preservice teachers develop their professional expertise by taking the opportunity to engage in learning mathematics through productive struggle.

The purpose of this study was to analyze the factors influencing of separation and the time of separation for middle and old aged self-employed workers. The cox proportional hazards model was used in the first survey of KLoSA, 684 persons who were over 40 years old in 2006, using data up to the 5th period of 2014. The main findings of this study are as follows. First, the average duration of job for middle and old aged self-employed workers in 2005 was 15.5years. Of the total 684 workers, 214(31.3%) person was found to have lost their job during survey period. Second, gender, age at start up, and education level have significant effects on job separation of them. When women, when they were older at start up, when they were graduate the university or higher, increased their risk of leaving their businesses. Third, in the characteristic of their work, the type of job and job satisfaction were found to affect to job desertion. When people are engaged in accommodation and food business rather than agriculture and forestry fishery, when the satisfaction of the work is lower, the risk was high. Based on these conlusions, the following implications are suggested. First, it is necessary to establish a support strategy for female middle-aged and old self-employed and older workers who start their own business after their 60s. Second, it is necessary to support them to enter into various fields by utilizing their own aptitude and experience rather than establishing them in industries with low entry barriers. Third, it is necessary to develop policies to help improve job satisfaction in the working environment. In particular, it is necessary to ensure that high educated self-employed workers are satisfied with various compensations by self-employed.

The author conducted a records research named 'daily life and records.' The purpose of the research was to find an archive, if possible, that would be effective in promoting exchange and cooperation among people in their daily lives, and to distinguish what type of archive it would be, as well as how to let it naturally take place in their ordinary lives. For 4 months (August-December 2019) with 100 college students in their 20s, trial and error were repeated. There was no separate laboratory for the research, and it used regular school hours at universities. Although it is true that there was a control through power by the college system, the plot was centered on the sunshine policy. To human being there is a voluntary and positive attitude. If anyone begins to take this attitude it is difficult to stop such action. Through emotional support, this voluntary action was encouraged to take root. The experiment was an attempt to doubt the obvious, and to search for something new. From afar, this may seem irrelevant to archives. However, for the author who is a professional archivist, it was a time of records through control by Records principles. By organizing into a form of story, its archival implications are observed.

I had an interview with some unemployed career staffs who had retired and worked for more than twenty years in order to research impacting elements on reemployment for l retired special security government officials. This interview included an officer and a consultant for supporting employment in order to explore compacting elements on retired security government official's reemployment. Looking over analysis results, first, there is a shortage of reemployment opportunities and information. The job applicant's employment requirements are not in accordance with the company's employment conditions. They don't have enough professional experience necessary for employment. There is no positive employment supporting counterplan or vocational education program in the organization. Second, their insight about finding a job is high for the current employment market condition. The reemployment offices have a very difficult task because job applicants prefer a full-time job which offers long term work and guarantees a social position. Third, it is a huge obstacle to undertake going into various enterprises and fields because they don't have the right mind set and enough preparation for reemployment. Moreover, they would prefer to depend on organization employment support rather than getting a new job by themselves when they don't possess other careers' qualifications. Finally, they know that social networks and personal connections are extremely important in obtaining vocations, but actually have poor social networks and few personal connections. Accordingly, Their organization and related persons need to reflect on analysis results about impacting elements on reemployment for retired special security government officials.

Objective : Questionnaires completed by occupational therapists and patients in institutions conducting a "Pilot Project of Rehabilitation Medical Institutions" were used to determine whether occupational therapy was able to establish appropriate patient support systems for return to home and community. Methods : The questionnaire was completed by 293 occupational therapists from 13 institutions conducting pilot projects and 296 patients from 8 institutions who were able to respond. Results : Although the Pilot Project of Rehabilitation Medical Institutions is being implemented to enable early return of patients to activities of daily living, the most important therapeutic goal is not efficiently applied. In addition, since the health insurance systems utilized in medical institutions are applied as in the pilot project, there is no basis for evaluation and mediation of practical daily activities and vocational rehabilitation for actual return to the community. Conclusion : Through a detailed review of the pilot project, it will be necessary to improve the quality of life through the early return of patients to social activity, and to make practical improvements to reduce unnecessary societal expenditures.

Objectives: Presenteeism is known to be a much more economically damaging social cost than disease rest while going to work despite physical pain. Since COVID-19, social discussions on the sickness benefit have been taking place as a countermeasure against presenteeism, and in particular, farmers and fishermen do not have an institutional mechanism for livelihood support when a disease other than work occurs. This study attempted to examine the relationship between agricultural, fishing, and forestry workers and presenteeism using the 6th Korean Work Conditions Survey. Methods: From October 2020 to January 2021, data from the 6th working conditions survey conducted on 17 cities and provinces in Korea were used, and a total of 34,981 people were studied. Control variables were gender, age, self-health assessment, education level, night work, shift work, monthly income, occupation, working hours per week, and employment status. Results: As a result of the analysis, farmers and fishermen showed the characteristics of the self-employed and the elderly, and as a result of the regression analysis, when farmers and fishermen analyzed the relationship with presenteeism tendency compared to other industry workers, farmers and fishermen increased by 23% compared to other industry groups. Conclusion: This study is significant in that it has representation by utilizing the 6th working conditions survey and objectively suggests the need for a sickness benefit for farmers and fishermen who may be overlooked in the sickness benefit.

Private forestland in Korea occupies about 48 percent of the total land area. But, the ownership size is too small to expect self-supporting management of forestowners. In order to improve individual management of the small-sized forest through the to the state of self-support, a cooperative forest management has been demanded, enlargement of the size of the management units by combining the different individual management units. The cooperative management of the private forest is to combine forestry production factors such as forestland, labor-power, and capitals according to the agreement. For the cooperative forest management, a proper plan should be established and well-trained working-crew should be produced. In addition, forestry facilities should be provided and operated jointly. Though the cooperative forest management by owners is considered to be favorable theoretically, it is difficult for forestowners including many nonresidents to organize the forest management cooperatives without outside help. Therefore, intensive pulblication and extension programmes are required and a financial support by the government should be followed.
