  • Tasks of multiple solutions have been said to be suitable for the cultivation of mathematical creativity. However, studies on the fact that multiple solutions presented by students are useful or meaningful, and students' thoughts while finding multiple solutions are very short. In this study, we set goals to confirm the qualitative differences among the multiple solutions presented by the students and, if present, from the viewpoint of mathematical creativity. For this reason, after presenting the set of tasks of the two versions to eight mathematically gifted students of the second-grade middle school, we analyzed qualitative differences that appeared among the solutions. In the study, there was a difference among the solution presented first and the solutions presented later, and qualitatively substantial differences in terms of flexibility and creativity. In this regard, it was concluded that the need to account for such qualitative differences in designing and applying multiple solutions should be considered.

  • 선호구조의 논리를 결정모델에 적용시킬 때 선호구조는 일반적으로 특정 수치적 순서화 조건을 만족하게끔 표현된다. 그래야 주어진 선택지들을 둘러싼 개인 혹은 집단의 선호구조에 관한 정보가 형식적으로 표출될 수 있다고 여겨져 왔다. 그러나 선호구조의 수치적 순서화에 의해서만 선호관계의 정보가 형식적으로 표출될 수 있다는 성각은 일종의 독단이다. 더욱이 다양한 선택지의 결합에 의한 선호구조의 정보 이동은 기존의 수치적 순서화 속에서 제대로 다루어질 수 없다. 하나의 대안으로서 선형대수의 그래프이론에 바탕을 둔 선호구조의 질적 순서화 방식을 제안한다. 개인 혹은 집단의 선호구조에 관한 정보는 제안될 질적 순서화에 의해 보다 포괄적으로 다루어질 수 있다.

Methods : Analyzed the characteristics of 17 single subject research papers (independent variable, study design, study subject, total number of session, study period, intervention time, intervention place, dependent variable, measuring tool and result) published between 2002 and 2013 using the document delivery service of Korean Society of Occupational Therapy, National Discovery for Science Leaders (NDSL), Nuri Media (DBpia), Research Information Sharing Service (RISS), Korean Studies Information Service System (KISS) and National Assembly Library and evaluated the literatures using quality evaluation scale. Results : According to the analysis result on the literature characteristics, reversal design was the most used study method. Total number of session was 10 sessions to 34 sessions. Study period was 4 weeks to 16 weeks. Intervention time was 8 minutes to 70 minutes and most interventions were done in occupational therapy room or sensory integration therapy room. According to the result of quality level evaluation, 4 papers out of 17 papers were on high level and remaining papers were on intermediate level. However, there was no study which included intervention blind. Conclusion : Suggested standards that need to be supplemented and discussions on qualitative improvement including repetitive research on the mediation effect during the application of the single subject research methodology, the securement of adequate data sections, and processing of a mediation blind. It is expected to be used as basic data for conducting a better qualitative research in the future.

  • This study is a qualitative case study of 5 substance abusers recovered from drug addiction. It is useful socially and practically to understand about the rehabilitation and its process of recovering from drug addiction. Since this study deals with very private and sensitive issues, qualitative research approach is suitable. Data were collected through one to one in-depth interviews, and were analyzed by using analysis within/cross cases suggested by Creswell(2007). 5 individual cases were presented including substance addicts experiences and recovery process through within-cases analysis. Based on the within-cases analysis, common themes were presented through cross-cases analysis. Total 19 themes, related with recovery from substance addicts, were derived from the five individual cases, and 4 common themes were classified. These 4 common themes were first, recovery of sense of reality, second, taking self-existing pattern, third, self reconstruction in the context of social network, fourth, self-love. Based on the study results and discussions, practical implications were suggested to help persons claiming recovery from substance addicts for their recovery and rehabilitation.

  • This paper analyzes and compares the effects of various government subsidies to improve labor productivity. Laborers are differentiated in learning ability, and duopsonists in the labor market sequentially determine the quality levels and wages of employed laborers in a two-stage noncooperative game under perfect information. If a subsidy is given to the advanced firm in quality and productivity of labor, that firm will prefer to intensify wage competition due to strengthening its competitiveness in the labor market, and attempt to lower its quality in order to reduce the degree of differentiation in quality. At that time, the other firm wants to avoid competition because of its weakened competitiveness, and may have an incentive to lower the quality level to expand the differentiation. If the government subsidizes low-quality and low-productivity firm, it is motivated to increase its quality level to reduce differentiation due to the strengthening of competitiveness, and its competitor has an incentive to improve the quality to expand the differentiation. And there is no significant difference in whether payments are made to laborers or firms.

  • This study started from the awareness of the issue if the citation index newly introduced to evaluate the quality of papers satisfies the proper timing matter, which is a component of performance indicators for the evaluation of government-funded R&D institutes. Accordingly, the study will propose improvement ways to shift the previous evaluation system to quality evaluation for mission-oriented R&D institutes by analysing and using the periodical characteristics such as citation half-life and immediacy index of papers. As a result, it turned out that the speed of academic change is getting faster in proportion to the dependency on the technological development but that the citation speed in the field of public technology is relatively slower and the speed of knowledge transfer in the fields related to industry is faster. In addition, the citation index among the R&D fields showed no differences, and the minimum period for citation index measurement with validity should be over 6 years. The problems of evaluation for mission-oriented R&D institutes were deducted based on the technical and statistical analysis results of the temporal characteristic of citation necessary for quality evaluation of performance among R&D fields. To solve the problems, policy alternatives for object and valid quality evaluation were proposed from the points of evaluation period and evaluation criteria.

  • The purpose of this study was to meta-synthesize the results of qualitative research that explored the experiences of nursing care in a domestic nurse to understand the phenomenon. The research method was a qualitative meta-synthesis study, which was analyzed using Thomas and Harden's methods. This was analyzed by searching for quality assessments for individual studies, extracting data for analysis, and meta-synthesizing the results. As a result of the study, it appeared as five synthetic themes. 1) Disaster nursing that begins with anxiety and fear, 2) Disaster nursing process: An atmosphere that feels even loneliness and burden in isolation and disconnection, 3) Disaster nursing process: Being in a poor and diverse environment, 4) Disaster nursing process: Although exhausted Endure and overcome. 5) After disaster care: A leap forward for development beyond mission and self-esteem. Conclusion, this study is expected to be a useful basic data for the development and application of nurse's disaster nursing programs and educational programs in the future.
