  • The purpose of this study was to investigate the elementary school teachers' perceptions about the science subject exclusive system. For this study, we developed the questionnaire to investigate teachers' perceptions and 43 elementary school teachers participated in the questionnaire test. And we used participation observation method to investigate characteristics the exclusive elementary science teacher and the elementary school homeroom teacher's science classes. After participation observation, we had interviews with exclusive elementary school science teacher and elementary school homeroom teacher. The results showed that elementary school teachers thought the science subject exclusive system was very necessary. And elementary school teachers thought that the exclusive elementary science teacher had higher professionality about teaching science subject than the homeroom teacher. Then, they expected that the strong points of science subject exclusive system would be some solution to the weak points of homeroom teachers' science classes. We suggested that it must be to enlarge the science subject exclusive system and develope in-service teacher program for the exclusive elementary science teachers.

  • After an emergency shutdown of a lead-bismuth fast reactor, thermal stratification occurs in the upper Plenum, which negatively impacts the integrity of the reactor structure and the residual heat removal capacity of natural circulation flow. The research on thermal stratification of reactors has mainly been conducted using an experimental method, a system program, and computational fluid dynamics (CFD). However, the equipment required for the experimental method is expensive, accuracy of the system program is unpredictable, and resources and time required for the CFD approach are extensive. To overcome the defects of thermal stratification analysis, a high-precision full-order thermal stratification model based on CFD technology is prepared in this study. Furthermore, a reduced-order model has been developed by combining proper orthogonal decomposition (POD) with Galerkin projection. A comparative analysis of thermal stratification with the proposed full-order model reveals that the reduced-order thermal stratification model can well simulate the temperature distribution in the upper plenum and rapidly elucidate the thermal stratification interface characteristics during the lead-bismuth fast reactor accident. Overall, this study provides an analytical tool for determining the thermal stratification mechanism and reducing thermal stratification.

  • Thin film electrodes have been intensively studied for active materials and current collectors to enhance the electrochemical performance. Here, porous structures of nickel-based oxide films, consisting of nickel oxide and copper (II) oxide, which was derived from the copper substrate during the annealing process, were deposited on metallic copper foils. The half-cell tests revealed excellent capacity retention after $80^{th}$ charge/discharge cycles. Some films showed an excess of the theoretical capacity of nickel oxides, which mainly originate from partially oxidized copper substrates during annealing. These results exhibit that both a preparation method of an active materials and partially oxidized current collectors could be important roles to apply thin film electrodes.

  • Chronic eosinophilic leukemia (CEL) is characterized by eosinophilia and organ damage. Imatinib is widely used for treating CEL, chronic myeloid leukemia (CML) and acute myeloid leukemia (AML). Unfortunately, the cancer cells gain resistance against the drug after prolonged molecular-targeted therapies. Imatinib-resistant EoL-1 (EoL-1-IR) cells were produced from chronic eosinophilic leukemia cells (EoL-1) after treatment with imatinib for a long duration. Two-dimensional electrophoresis (2-DE) analysis revealed numerous protein variations in the EoL-1 and EoL-1-IR sub-types. Compared to the EoL-1 cells, expression levels of TIP49, RBBP7, ${\alpha}$-enolase, adenosine deaminase, C protein, galactokinase, eukaryotic translation initiation factor, $IFN-{\gamma}$, and human protein homologous to DROER were increased, whereas core I protein, proteasome subunit p42, heterogeneous ribonuclear particle protein, chain B, and nucleoside diphosphate were decreased in the EoL-1-IR cells. Taken together, these results contribute to understanding the pathogenic mechanism of drug-resistant diseases.

  • Purpose: The effects of job participation on self-esteem and life satisfaction were investigated. Methods: Seventy residents of D welfare center located in G city who were >60 yr-of-age were selected for the study. The SERS research tool (Nugent and Thomas, 1993; modified by Koh, 2002) was used to assess self-esteem before and after a job participation program. The Cronbach's ${\alpha}$value-based reliability of this tool was 0.923 and 0.920 before and after the job participation program, respectively. Cronbach's ${\alpha}$value-based life satisfaction as measured according to Choi (1986) was 0.932 and 0.933 before and after the job participation program, respectively. Results: The hypothesis that job participation program increases self esteem was supported by the results. The mean self esteem of subjects before and after the job program, 3.31 and 3.48, respectively, represented a significant increase. The hypothesis that the job participation program increases life satisfaction was supported by the results. The mean life satisfaction index of subjects before and after the program, 3.04 and 3.24, respectively, represents a significant increase. Conclusions: Increased job opportunities and income guarantee for adults, particularly the elderly, can increase self-esteem, life satisfaction, and emotional stability.

  • Purpose : This study aims to investigate occupational therapy students' perceptions of sensory integration therapy and the effect of an educational program on these perceptions and future preferences. Methods : The participants were 200 occupational therapy students in Busan and Gyeongsangnam-do. A primary survey was first conducted to shed light on students' perceptions of sensory integration therapy, followed by an education program on sensory integration provided through an online video. After this training on sensory integration therapy, an additional survey assessed the their preferred employment routes and intention to take educational courses on clinical sensory integration therapy in the future. A secondary survey was then conducted, using the same form as the primary survey, to identify changes in the students' perceptions of and preferences for sensory integration therapy. A frequency analysis using descriptive statistics was employed to identify the participants' general characteristics, employment-related preferences, and intention to take courses on sensory integration, and a paired samples t-test was used for a comparative analysis of the students' perceptions before and after the education program. Results : In terms of the students' perceptions of sensory integration therapy, the variables of efficiency, facilitation, and expertise showed statistically significant differences before and after the educational program, which resulted in a positive change in their overall perceptions of the therapy after the program. In relation to their preferred employment routes after the program, 100 students (50 %) answered the "field of adults," and 100 (50 %) students answered the "field of children." Conclusion : The findings of this study demonstrated that sensory integration education positively influences occupational therapy students' preferences for and perceptions of sensory integration therapy. Additional research is recommended to organize a more systematic education program and investigate employees in organizations related to children with disabilities.
