The growth and development of Gwangyang city was a result of the POSCO Gwangyang Works, and Gwangyang city is one of typical firm citys in Korea. The objective of this study is to identify and examine the change of migration and population structure in Gwangyang city from 2001 to 2010. Since 1981, total number of population of Gwangyang city increased from 78,478 in 1981 to 145,512 in 2010. The population structure by age was changed with population increase since 2001, and 30-40 aging group was 35% of total in 2010. During 2001-2010, the netmigraion showed -2,925 people, however, the number of inmigrants were overtaking the number of out-migrants since 2008. The most common reason of in-migrants was occupation(49.5%). Factors influencing Gwangyang City's population growth and oversupply are the location of POSCO Gwangyang Works and steel-related enterprises, opening and construction of Gwangyang container berth, the related development projects and establishment of Gwangyang Bay Area Free Economic Zone, and the local policies of Gwangyang City connected with these large-scale national projects. As a result, the number of manufacturing-related businesses increased due to various regional development projects conducted in Gwangyang City, and the growth of the business continued to increase due to the increase of younger people and births.

The main purpose of this paper is to examine selectivity and rasons for move of internal migrants in Korea. There have only been a few studies available on the issues of selectivity and reasons for move of internal migration in Korea, mainly due to the lack of appropriate data. The main source of data for this analysis come from the raw data set of the 1997 Special Migration Survey conducted by the National Statistical Office. Analysis of selectivity of those who moved across the provincial boundary revealed that females, young adults, singles in their marital status and more educated are more likely to move. Among various reasons for move, employment related reason is the most important for all migration streams. But with different migration streams, diverse patterns are emerged. For those who moved into the Capital Region, employment related reason is outstanding. But those who moved out from the Capital Region, moved for employment as well as family related reasons. For movement within the Capital Region, housing related reason is equally important together with employment and family reason. The analysis also found that among individual attributes, age and marital status affect most significantly to the reasons for move. Education level and housing ownership are also important for explaining for variations in reasons for move.

This study aims to implement analyses of types of conflict perceived by teachers and coping methods. Researchers analyzed 561 survey responses of elementary and secondary teachers using independent t-test and ANOVA. Results are as follows. First, regarding perception of teacher conflict, there were statistically significant mean differences by teacher role, status, and location for conflict toward colleague, parents, and policy, by teacher role and status for conflict toward students, by location for conflict toward administrators, and by teacher role and location for conflict toward staff. Second, in regard to coping methods, gender and teacher status in coping methods for students and gender and teacher role in coping methods for policy showed different aspects in the number of responses. Researchers suggested principals' understanding organizational conflict and enhancing conflict management skills and teachers' discussing strategies for conflict resolution.

Simulations were performed using a Monte Carlo technique in order to show physical phenomena occurring when a heavy charged particle such as proton or alpha particle traverses the medium. It was confirmed that the sharp Bragg peak occurred deeper in the water with the increasing proton energy. It is found that the use of such a sharp Bragg peak due to heavy charged particles would be far superior to the case of the photon or electron, since the absorbed dose in the target tissues would be better localized, thereby minimizing the damage to the surrounding tissues.

The purpose of this study is to investigate factors affecting conflict of teachers in school. Researchers selected independent variables in personal, school, and local levels and analyzed their influence on conflict of faculty and staff, students and parents, and educational policy. We used 561 survey responses of teachers working in S City Office of Education and conducted hierarchical multiple regression analysis using SPSS 24.0. For results, we found out that variables such as career in the level of person, homeroom teacher and status in the level of school, and location in the level of region were statistically significant. Researchers suggested possible solutions which can be considered by school district and school officials.

To evaluate the achievements of the Solar School Project that has been implemented in twelve African countries since 2013, a case study was implemented in Kenya and in Uganda to investigate networking activities, student accessibility to computers, the frequency of student computer use, the extent to which teaching quality was improved by the enhanced accessibility to ICT-based teaching and learning practices. The results showed the followings. First, Solar Schools have significantly improved the rates of enrollment, transferring, and school attendance. Second, Solar Schools have organized local and invitational training programs to build the capacities of teachers. Third, Solar Schools have facilitated change in neighboring schools and local communities. Fourth, the participants are required to have a clear vision, take ownership of the project, and make a commitment to continuing their individual efforts toward empowerment.

The Korean military is having difficulty maintaining combat power due to the insufficient troop numbers caused by a demographic cliff and the reduction of the mandatory military service period. Recently, discussions on improving the military training system have increased significantly. This paper proposes an optimization model to establish military training schedules to improve combat power. The oblivion and learning effects on training tasks were quantified through a survey and applied to the model. The objective value, combat power, was calculated based on the total task scores of the unit members and the number of task failures after four weeks. The scenarios were configured by the change in educational conditions and initial scores of some tasks. As a result of scenario experiments, combat power has increased by at least 10% and up to 77%, which is sufficient to maintain combat power considering the change in troops. In addition, the planning of combat skill tasks has a significant impact on combat power. Through this research model, it is expected that military training managers will be able to establish a training schedule that maintains or improves the combat power of troops effectively.

The purpose of this study was to find out how to operate Technology Home Economics in the 2009 revised national curriculum and Home Economics teachers perception on the current states in the middle schools, focused on intensive course-taking, block-time, and total hours to take the course. Data were collected from the 118 Home Economics teachers nationwide through e-mail from May 25 to June 4, 2011, and analyzed with frequencies, percentage, means, t-test, cross-tabulations, and ANOVA. The results showed that Technology Home Economics was intensively taken in the most of all schools(91.5%) during 4 semesters by senior and freshmen or junior. Teachers were relatively less involved in the decision making process for intensive course-taking than did the school managers and dissatisfied with the fact of intensive course-taking. But a few school adopted block-time and most teachers did not think it was necessary. Over half of schools offered the same 16 hours of Technology Home Economics as in the previous 2007 revised curriculum, but nearly 2 out of 5 schools reduced the hours from 1 to 8 with an average of 2.8 hours. To keep the necessary hours to teach the full contents of Technology Home Economics should be protected. The follow-up research needs to be conducted to investigate the changes in the perception of Home Economics teachers.
