In Korea, the dependence on living donations is high due to the shortage of organs available for donation compared to the number of people waiting for transplants and the number of living organ donations continues to increase. In particular, the number of living-donor transplantations is high worldwide, highlighting the importance of pre-transplant psychosocial evaluation of living kidney donors. According to previous studies, when evaluating living organ donors before transplantation, it is crucial to determine whether the donor can give informed consent and be aware of the risks after surgery. Pre-transplant evaluation tests such as ELPAT living organ donor Psychological Assessment Tool (EPAT), Live Donor Assessment Tool (LDAT), Living Donation Expectancies Questionnaire (LDEQ), Minnesota Multiphasic Personality Inventory-2 questionnaire (MMPI-2) and Temperament and Character Inventory (TCI) are conducted for donors. After reviewing the literature on these pre-transplant psychosocial assessment tools, we will also look at legal considerations for living kidney donors in Korea and suggest an effective and essential pre-transplant screening evaluation method for living kidney transplant donors.

The purpose of this study is to explore evaluation criteria that pre-service elementary teachers employ as they evaluate and select models to explain electric circuits. Thirty junior students in a university of education have participated in the study as a part of the science education course in which they were enrolled. The lessons for the participants have been organized as a cyclic sequence of different modeling pedagogies including the expressive, experimental, and evaluative modeling. The pre-service teachers have been given five electric circuits in order and asked to create models and further develop them through peer discussion. Their modeling activities have been video- or audio-recorded, and the recordings and their transcripts have been analyzed using a framework of model evaluation criteria. It reveals that the types and frequencies of evaluation criteria used are different between situations of model development and model selection. While empirical and theoretical criteria have been used dominantly in both situations, more various criteria have been employed in the situation where the pre-service teachers selected one model among alternatives. Implications for science education and science education research have been suggested.

Objective : The purpose of this study is to confirm whether the effectiveness of the program is sustainable 9 months after project completion for the children and adolescents participating in a childcare and rehabilitation support project. Methods : This study was carried out in three phases: pre-(2016.5~6), post-(2016.10~12) and follow-up evaluation phases (2017.9) of 120 children and adolescents who participated in a treatment and rehabilitation of children project in 2016. The analysis was conducted using a repeated mesures ANOVA to identify changes in problem behaviors. Results : The problem behavior of preschoolers in middle and high schools decreased after the post-evaluation compared to the pre-evaluation, and the effect of treatment was maintained afterward. Elementary school students displayed fewer problem behaviors after the post-evaluation than in the pre-evaluation, and follow-up more. Conclusions : This study confirms that the effects of therapy are maintained for a long period of time. Furthermore, it has been confirmed that therapeutic intervention is effective for children and adolescents in foster care.

The purpose of this study is to develop and apply a teaching-learning plan of apartment house class to improve middle school students' empathy for home economics education and to verify its effect. The study was conducted in five stages: analysis, design, development, implementation, and evaluation using the ADDIE model. In the analysis phase, the study set learning objectives after analyzing how community housing is dealt with in the 2015 revised home economics curriculum and 12 current technology and home economics textbooks. In the design and development stage, in order to evaluate the validity of the experts and to improve the empathy ability, the study goal design, the composition of the learning elements, the development of the learning materials, and the pre and post-questionnaire for the students were developed. In the implementation stage, the empathic ability evaluation was carried out before and after the beginning of the first class by applying the teaching-learning process plan of the 8th class. In the evaluation stage, we examined whether the teaching-learning process developed in this study has a significant effect on empathy ability by evaluating the pre-post difference of empathy ability. As a result of examining the results of the pre - and post - evaluation of empathy ability for the results of this study, both cognitive and communicative factors were improved, and the apartment house class had a significant effect on the improvement of empathy ability.

The purpose of this study was to investigate the characteristics of lesson planning of pre-service elementary teachers to develop scientific communication skills for elementary school students. For this purpose, lesson plans and lesson planning journals written by the 53 pre-service teachers were collected and analyzed. The results of the research were as follows. The pre-service elementary teachers used an implicit and contextual approach to develop scientific communication skills. Teaching and learning activities for enhancing scientific communication were mainly conducted in words or in writing. There were many activities expressing elementary school students' thoughts and presenting the results of experiments in the lesson plan. There were many cases in which the pre-service teachers' lesson plans did not include the evaluation of scientific communication skills. In their lesson plans, there are a lot of mutual activities between teachers and students, team and whole students, and inter-students within teams together, and students' individual activities from requests of teachers. We found that the pre-service teachers had various difficulties when they planned the science lesson to develop scientific communication skills. The pre-service teachers were less likely to refer to specialized materials related to science education when planning their classes.

This study aims to provide answers to two questions regarding the supervision of pre-service mathematics teachers: 'Who should carry out the work of supervision?' and 'How can it most skillfully be done?' The answer to the first question seems to be that, for a variety of reasons, university teachers and mentors appear best suited to do the supervision in a cooperative relationship with pre-service teachers. The assumption that seems to underlie the collaborative supervision is that field-based experiences are necessary and useful components of professional development in pre-service teacher preparation programs. With respect to the second question, it is suggested that a non-judgemental approach should be considered, along with strategies and techniques for judgemental supervision, as a way to make math teacher supervision more meaningful and helpful for the improvement of teaching and long-term professional development. It is hoped that a continued exploration of models of teacher supervision and evaluation of their effectiveness will help pre-service math teachers, supervisors and mentors learn more about teaching and improve their own teaching.

TiNi alloy fiber was used to solve the problem of the tensile residual stress as the reinforced material. TiNi alloy fiber improves the tensile strength of composite by occurring compressive residual stress in the matrix using shape memory effect. In order to generate compressive residual stress in TiNi/Al6061 shape memory alloy(SMA) composite, 1, 3 and 5% pre-strains were applied to the composite in advance. It was also evaluated the effect of compressive residual stress corresponding to the pre-strain variation and the volume fraction of TiNi alloy. AE technique was used to clarify the microscopic damage behavior at high temperature and the effect of pre-strain in TiNi/Al6061 SMA composite. The results of the microscopic damage evaluation of TiNi/Al6061 SMA composite under various pre-strain using AE technique can be divided into three stage corresponding to the AE signals. AE counts and events were useful parameters to evaluate the fracture mechanism according to the variation of pre-strain. In addition, two dimensional AE source location technique was applied for monitoring the crack initiation and propagation in composite.

This study was conducted in order to evaluate the effects of brine pre-soaking at different concentrations and drying time on the quality characteristics of pork jerky. The physicochemical properties of pork jerky including final moisture content, water activity ($a_w$), shear force, microstructure, and thiobarbituric acid reactive substance (TBARS) values were investigated. The sensory attributes of pork jerky were evaluated and used as parameters for determining the optimum drying condition. The sliced pork samples were pre-soaked at salt concentrations ranging from 0 to 10% for 3 h and then dried at $70^{\circ}C$ for up to 10 h. The pre-soaked samples in the salt solution showed higher final moisture content than the control sample after drying for 10 h. The final moisture content of pork jerky increased with increasing salt concentrations. On the other hand, the water activity with regards to the pre-soaked samples in a 10% salt solution showed the lowest value for up to 8 h drying. The shear force values of pork jerky decreased with increasing salt concentration while the TBARS values of the samples increased with increasing salt concentrations. Sensory evaluation suggested that the color, flavor, juiciness, and tenderness of the pork jerky samples were improved by pre-soaking in a 2% salt solution and the highest likeability score of pork jerky among the samples were obtained by pre-soaking in a 2% salt solution prior to drying.
