With respect to the growth and development of innocity from improvements in leisure environments, this research examines the factors that affect the level of satisfaction of innocity leisure environments to propose political implications. In order to do so, 43 leisure activities were chosen, and the level of importance of those activities to the residents prior to moving to the innocity was compared to the level of satisfaction the residents felt regarding the activities after moving. As a result, 13 activities, including literature attendance, had greater levels of satisfaction after moving than the levels of importance prior to moving. The rest (30) activities showed the opposite results. We deduced the factors that affect the level of satisfaction by performing logistic regression analysis on 3 dependent variables. As a result, the static and passive leisure activities had higher satisfactory levels, whereas the dynamic and active had lower satisfactory levels. Thus, innocity must develop culture facilities quickly, expand exercise facilities to support sports activties, and promote tourism by improving and networking with tourist attractions in order to improve future satisfactory levels of leisure activities.

사상 유례없던 한여름 폭서가 한반도를 지나가고 환절기 9월이 다가왔다. 올여름은 그 어느 때 보다 환기의 중요성이 강조되었던 해이기도 하다. 국내 환기전문업체인 문터스코리아 (주)(대표 이주행)는 폭서 피해를 최소화하기 위해 환기시설이 들어간 농장들을 예의주시하며 비상 상태를 유지해왔다. 그 결과 거래농장들의 경우 환기로 인한 문제로 발생한 피해는 찾아볼 수 없었다. 본고는 국내 양계 환기시스템 하면 자타가 공인하는 문터스코리아(주)를 찾아 다국적 회사이면서 국내에서 많은 농가들에 호응을 받고 있는 비결, 회사 경영방안과 앞으로의 계획 등을 들어 보았다. 문터스코리아(주)는 20명의 젊은 직원이 근무하고 있으며, 현재 서울시 강남에 본사를 두고 있고, 천안과 김해에 지사를 운영하고 있다.

The track of high-speed railway get deteriorated according as using it. In that case, the maintenance jobs are needed for improvement of track quality. A scheduling problem for the track maintenance of high-speed railway is to determine the jobs should be performed daily. In the problem, the set of jobs for maintenance is given. Each job has it's parameters such as due date, emergency level, and processing time. In addition, jobs can be worked during a certain fixed time when the train doesn't move. In this study, we developed a mathematical model of the scheduling problem for the maintenance of high-speed railway and solved the problem using the ILOG CPLEX library.

The meaning of the color which has from modern interior space has played important role, i.e. color itself Is the concept creation tool as well as the unique expression sphere in field of interior space far away from fixed idea relevant to the existing color which was only simple decoration or secondary element in space. Thus, this current work expresses that the color is related with decoration effect as well as basic designed-conceptual work process including the space is formed. Furthermore, through the side-composition with color, It activates the various space aspect perceptually, which created the colorful environment in using lightning, reflection of glass and penetrated nature etc. The keyword on color concept is as like various aspects, third dimension, non-materiality and symbolical meaning. In addition, it provides the color space equipped with functionality and artistry capable to arouse the diverse sensual capacity to space users on default of color image language.

In this paper, optimized model was designed for the starting characteristic of the Single-Phase Line-Start Permanent Magnet Synchronous Motor by using the Design of Experiment. A field pole angle, thickness and distance from center axis of permanent magnet were selected as design factor. We executed the transient state characteristic analysis of 8 test models. The transient state characteristic analysis was executed by using the 2 dimensional Finite Element Method and the Time Difference Method. We checked the fact that the selected design factor affected starting characteristic of the Line-Start Permanent Magnet Synchronous Motor. Depend on this result we found the optimized design point by using the response optimization.

Migration is defined as the movement of people between residential places, and represents interactions between regions. Changes in migration involve changes in both the number of migrants toward/from regions and migration patterns across regions. However, most migration studies have focused only on the change in migrants, while no empirical study captures changes in migration patterns. In this paper, I present a function using the cosine similarity to measure changes in migration patterns, and apply it to 2001-2016 migration data of Korea. The results show that the migration patterns of Korea shifted in 2007, resulting in two distinct clusters. Local areas experienced various migration pattern changes despite few changes in the number of migrants.

Throughout the economic development era of Korea, migration occurred within a spatial hierarchy, with upward flows from rural areas to urban. The concept of step migration is a typical theory to explain these upward migration flows. Recent migration data and trends, however, indicate that migration-pattern regime shows strongly opposite-direction flows, with many of the major migration flowing downward on this national-spatial hierarchy, away from urban areas. In this study, we examine the most recent structure of migration flows up and down within the national-spatial hierarchy. We define seven tiers to tabulate origin-destination migration flows from population density of local administrative districts for the period 2001-2014, and then analyze the migration patterns between the tiers over time. The results show differentiated patterns of migration within the national-spatial hierarchy over time including specific states of migrants' life cycles.

4대강 살리기 프로젝트 중 하나인 금강 살리기에는 현재 금남보, 금강보, 부여보가 신설 예정이다. 본 연구에서는 금강 살리기 사업 중 부여보에 대하여 계획홍수량인 100년빈도 유량의 흐름 예측을 위한 1 2차원 수치해석과 수리적인 형상을 실제 흐름으로 관찰하기 위한 수리모형실험을 실시하여 부여보의 치수안정성을 검토 및 분석하였다. 본 연구를 위하여 1차원 수치해석은 HEC-RAS모형, 2차원 수치해석은 SMS RMA2 모형을 사용하였다. 수리모형 실험은 부여보 기준 상 하류 3km 구간에 대하여 축척 1/60 정상모형으로 제작하였다. 그 결과 부여보 상 하류구간에서 원활한 흐름특성이 나타났으며, 100년빈도 유량에 대하여 수치해석과 수리모형실험 모두 계획홍수위를 넘지 않는 것으로 나타났다.

The purpose of the research is to propose an integrated project planning process and its implementation method. Although there is increasing interest in the application of the Earned Value Management(EVM) method in the project management area, the progress and maturity of the technical performance have not been included in assessing the Earned Value. The main concept of the planning process is to use cost, schedule, as well as the technical performance in the assessment of the Earned Value Management for Military R&D project management practices. The resulting process can enhance the efficiency of the project work by eliminating the currently duplicated activities between traditional project planning process and the newly implemented Earned Value Management process and by shortening the early planning process duration of projects adopting EVM practices.
