Purpose: The present study was done to discover the structure of universal actual experiences 'Considering tomorrow' of health and quality of life among North Korean refugees in terms of the socio-cultural context of South Korea. Method: The research question was 'what is the structure of the actual experience of 'Considering tomorrow?', which was examined based on the Parse's human becoming research method. Five North Korean adult refugees were recruited from a National Reconciliation Committee in Seoul/Incheon. The data was gathered from dialogues and collected from February, 2006 to November, 2006. Results: The structures found in this study were: 'hope for future life by taking responsibility and having harmony with South Koreans, by forming an integrated identification; having a chance for positive engagement, by attaining human freedom and hope; feeling respected, by assimilating self to the new world; getting freedom back, by facing a new challenge and preparing self for a new social role; overcoming cultural differences with fortified hardiness for survival, by making a decision for a life course with individual growth. In addition, conceptual integration was that 'Considering tomorrow is transforming the enabling-limiting values'. Conclusion: Health professionals need to know North Korean refugees' psychological difficulties, expectations of treatment, help seeking behavior, and expectations from mainstream culture. Additionally, understanding North Korean refugees' needs for reality, health education and a multi-disciplinary team approach are necessary to improve their health.

We have calculated the reaction probability and the reaction cross-section of the $N(^4S)+O_2(X^3\sum_{g}^{-})\;\rightarrow\;NO(X^2\Pi)+O(^3P)$ reaction by the quasiclassical trajectory method with the 6th-order explicit symplectic algorithm, based on a new ground potential energy surface. The advantage of the 6th-order explicit symplectic algorithm, conserving both the total energy and the total angular momentum of the reaction system during the numerical integration of canonical equations, has firstly analyzed in this work, which make the calculation of the reaction probability more reliable. The variation of the reaction probability with the impact parameter and the influence of the relative translational energy on the reaction cross-section of the reaction have been discussed in detail. And the fact is found by the comparison that the reaction probability and the reaction cross-section of the reaction estimated in this work are more reasonable than the theoretical ones determined by Gilibert et al.

Purpose of the Study : This research aims to examine the core values of ESG (Environmental, Social, and Governance) from a Christian perspective and explore the direction of Christian education that fosters character traits such as service, compassion, responsibility, and sharing through the process of design thinking. Content and Method of the Study : By investigating the background and definition of ESG, ESG practices in businesses, and the current status and values of ESG education in universities, this study examined the core values of ESG from a Christian perspective. Subsequently, the study explored and proposed directions for applying ESG education methods infused with character traits such as service, compassion, responsibility, and sharing through the process of design thinking. Conclusion and Recommendations : Through this study, the core values of ESG have been derived as elements from a Christian perspective, and exploration has been made on how to integrate them into the design thinking process. Consequently, this study has identified the potential to integrate ESG into the design thinking process with a focus on elements from the perspective of Christian education. This could serve as foundational material for education seeking to apply ESG through the integration of design thinking, and it is hoped that it will be helpful as a basis for further research. Subsequent studies should aim to construct a more systematic framework for the direction proposed in this study through expert reviews.

A three-dimensional Lagrangian explicit time-integration finite element code for analyzing the dynamic impact phenomena was developed. It uses four node tetrahedral elements. In order to consider the effects of strain rate hardening, strain hardening and thermal softening, which are frequently observed in high-velocity deformation phenomena, Johnson-Cook model is used as constitutive model. For more accurate and robust contact force computation, the defense node contact algorithm was adopted and implemented. In order to evaluate the performance of the newly developed three-dimensional hydrocode NET3D, numerical simulations of the oblique impact of mild steel plate by mild steel sphere were carried out. Ballistic limit about various oblique angle between 0 degree and 80 degree was estimated through a series of simulations with different initial velocities of sphere. Element eroding by equivalent plastic strain was applied to mild steel spheres and targets. Ballistic limits and fracture characteristics obtained from simulation were compared with experimental results conducted by Finnegan et al. From numerical studies, the following conclusions were reached. (1) Simulations could successfully reproduce the key features observed in experiment such as tensile failure termed "disking"at normal impacts and outwards bending of partially formed plus segments termed "hinge-mode"at oblique impacts. (2) Simulation results fur 60 degrees oblique impact at 0.70 km/s and 0.91 km/s were compared with experimental results and Eulerian hydrocode CTH simulation results. The Lagrangian code NET3D is superior to Eulerian code CTH in the computational accuracy. Agreement with the experimentally obtained final deformed cross-sections of the projectile is excellent. (3) Agreement with the experimental ballistic limit data, particularly at the high-obliquity impacts, is reasonably good. (4) The simulation result is not very sensitive to eroding condition but slightly influenced by friction coefficient.

Electrical impedance tomography is an imaging technique to reconstruct the internal conductivity distribution based on applied currents and measured voltages in a domain of interest. In this paper, a modified Gauss-Newton method is proposed for conductivity image reconstruction. In the proposed method, the dimension of the inverse term is reduced by replacing the number of elements with the number of measurement data in the conductivity updating equation of the conventional Gauss-Newton method. Therefore, the computation time is greatly reduced as compared to the conventional Gauss-Newton method. Moreover, the regularization parameter is selected by computing the minimum-maximum from the diagonal components of the Jacobian matrix at every iteration. The numerical experiments with several scenarios were carried out to evaluate the reconstruction performance of the proposed method.

The number of schools which have passed 30 years after the construction takes up 30% (5% falling to class D and E) in Korea. So, the offices of education across the nation conduct large works for the expansion, improvement and renovation of the school. But as the work takes a lot of time, the work is also conducted while the students are studying at the schools. The work at the school causes the noise, dust, vibration as the school often has the reinforced concrete structure. So, as the windows are closed to prevent the nuisance from hampering the education, the problems related to the illumination, ventilation, and control of humidity and temperature are give damages to students studying the school buildings. Actually, as the current renovation or expansion is conducted across the nation due to the implementation of the new education system and the resulting integration and construction of hub school, specialized school, meister school and it causes a lot of nuisance to the learning students and others, there are a lot of complaints from concerned people. Accordingly this study suggests the method of evaluating the factors which affect the learning environment such as the noise, dust or fine dust and reducing the nuisances to the level proper for the learning environment when the existing school is expanded, improved or renovated.

This study intended to analyze pre-service elementary teachers' perceptions of teacher knowledge based on the Technological, Pedagogical, and Content Knowledge (TPACK) framework. Seventy-four pre-service elementary teachers who were enrolled at an University of Education located in mid-continent of Korea participated in a survey. Results of the survey was analyzed using Importance-Performance Analysis (IPA) method. It was found that perception of importance was significantly higher than that of performance at all seven domains of the TPACK. IPA matrix extracted from the survey indicates that Technological Content Knowledge (TCK), Technological Pedagogical Knowledge (TPK), and TPACK which are related to technology especially need to develop. Results of this study also show the necessity to support pre-service teachers so that they can have opportunities to develop and use technology-related knowledge and skills. This study especially implies that technological knowledge needs to be integrated with content and pedagogical knowledge when implementing curriculum and educational programs for pre-servie elementary teachers.
