Container terminals at Gwangyang Port are operated by three container operators: A, B and C. Ultimately, there is consensus that a single operator should operate all terminals so that economies of scale can be achieved even in the operation of the container terminal. Integration between operators has a positive effect on both operators and shipping companies. From the operator's point of view, overlapping fixed costs between operators can be unified, reducing overall costs and utilizing spare facilities. On the other hand, from the viewpoint of the shipping company, it is possible to ensure stable use of the port facilities and always allow berthing, reduce days on demurrage and ship waiting, and provide one-stop service for work. However, existing cases of operators' integration or relocation of terminals remained to estimate the expected effects of alternatives, emphasizing only the financial point of view. The port terminal is a large system, and it is important to consider that it is an aggregate of major logistics facilities and equipment. Moreover, if the estimation can be made by quantifying the expected effect, the justification of the terminals' relocation can be further emphasized. Therefore, it is very important to estimate the expected effect from the viewpoint of systemic operation. Moreover, the need for operators' integration can be further emphasized if it can be estimated through quantification of expected effects. Currently, three alternatives are considered as alternatives to the terminals' relocation, and in this study, the optimal plan was derived for the 3 alternatives by the linear planning model of the minimum shuttle transportation cost in the terminal. The optimal plan is alternative 2, which shows the most advantageous integration effect in terms of expected effects. Alternative 2 integrates the B terminal into the C terminal, and the A terminal operates independently as it is.

공공기관들의 지방이전은 '국가균형발전'을 위해 시행된 정책으로 2019년에 한국과학기술기획평가원의 충북혁신도시 이전을 끝으로 마무리되었다. 전력공기업 또한 전국 8개 지역으로 이전을 완료하였는데, 본 연구에서는 지방이전이라는 조직변화에 따른 심리적, 경제적, 생활환경 등 다양한 측면에서의 변화와 그 영향을 실증적으로 분석하였다. 세부적으로는 이들 기관 구성원들의 조직변화에 따른 심리상태를 바탕으로 공공봉사동기와 직무태도 간의 구조관계를 파악하여, 전력공기업의 지방이전 이후의 안정화 방안을 모색하는 한편, 2차 공공기관 지방 이전에 의한 '국가균형발전'에 기여할 수 있는 시사점을 제시하고자 한다. 이번 연구에서 지방이전에 따른 심리상태와 조직몰입과는 통계적으로 유의한 관계가 있고, 기대심리가 높을수록 조직몰입이 높아지는 관계를 보인 반면, 불안심리는 조직몰입과 관계가 없는 것으로 분석되었다. 기대심리와 이직의도는 유의적이지 않았으나, 불안심리가 강할수록 이직의도가 높아지는 것으로 나타났다. 또한 기대심리가 높을수록 공공봉사동기도 증가하며, 불안심리가 높을수록 공공봉사동기는 낮아지는 것으로 분석되었다. 그리고 공공봉사동기가 클수록 조직몰입 또한 커지지만, 이직의도와는 유의적이지 않는 것으로 나타났다. 조직변화로 인한 기대심리와 이직의도 간 공공봉사동기의 조절효과는 유의적이지 않았으나, 그 이외 불안심리는 공공봉사동기의 조절효과가 유의적인 관계를 형성하는 것으로 분석되었다. 특히 조직변화에 대한 기대심리가 공공봉사동기에 미치는 영향은 전력공기업 구성원들이 지방으로 이전하기 전 보다는 이후에 크며, 지방으로 이전 한 이후에는 기대심리와 이직의도의 관계가 낮아진다는 점을 실증적으로 규명하였다.

In this paper, a fast migration method is proposed. Our method executes local relocation on a model placement where an additional module is added to it for modification with a minimum number of displacements. This method is based on mean-field annealing (MFA), which produces a solution as reliable as a previously used method called simulated annealing. The proposed method requires substantially less time and hardware, and it is less sensitive to the initial and final temperatures. In addition, the solution runtime is mostly independent of the size and complexity of the input model placement. Our proposed MFA algorithm is optimized by enabling module rotation inside an energy function called permissible distances preservation energy. This, in turn, allows more options in moving the engaged modules. Finally, a three-phase cooling process governs the convergence of problem variables called neurons or spins.

The CRP(Container Relocation Problem) algorithms pursuing efficient container relocation of wharf container terminal can not be deterministic because of the large number of layout cases. Therefore, the CRP algorithms should adopt trial and error intuition and experimental heuristic techniques. And because the heuristic can not be best for all individual cases, it is necessary to find metrics which show excellent on average. In this study, we analyze GLAH(Greedy Look-ahead Heuristic) algorithm which is one of the recent researches in detail, and propose a heuristic metrics HOB(sum of the height differences between a badly placed container and the containers prohibited by the badly placed container) to improve the algorithm. The experimental results show that the improved algorithm, GLAH', exerts a stable performance increment of up to 3.8% in our test data, and as the layout size grows, the performance increment gap increases.

The purpose of this study is to investigate the effect of functional ability on relocation among the elderly. Longitudinal data from the Asset and Health Dynamics among the Oldest Old (1993, 1995) were analyzed for 6,225 respondents aged 70 or older. Among functional ability measures, difficulties in advanced activities of daily living (i. e., making telephone calls, taking medications, and managing money), lower body activities (i. e., walking several blocks, climbing one flight of stairs, pulling or pushing large objects, and carrying over 10 pounds), and household activities of daily living (i. e., preparing hot meals and shopping for groceries) were the predictors of increased residential move. Difficulties in basic activities of daily living (i. e., bathing, dressing, getting in and out, and using the toilet) were strongly related to increased entrance into an institutional care facility. Efforts to enhance the independent living of the elderly in the community setting should target the compensation of these functional difficulties.

This paper presents a 3D shape optimization algorithm for electromagnetic devices using the design sensitivity analysis with finite element method. The structural deformation analysis based on the deformation theory of the elastic body under stress is used for mesh renewing. The design sensitivity and adjoint variable formulae are derived for the 3D finite element method with edge element. The results of sensitivity analysis are used as the input data of the structural analysis to calculate the relocation of the nodal points. This method makes it possible that the new mesh of analysis region can be obtained from the initial mesh without regeneration. The proposed algorithm is applied to the shape optimization of 3D electromagnet pole to net a uniform flux density at the target region.

This study was carried out to obtain basic data for architectural plans about factors on the facilities relocation needed in management of variation type. For this, floor plans of thirteen middle schools located in Korea and Japan were compared. The results showed a successful conversion to block system according to each subject after remodeling in the schools of our country, however, a monotonous spacial composition excluded other spaces such as media space, teachers' station and preparation room was also shown. These mentioned spaces were important factors in the investigated schools of Japan. By the results of the spacial composition about each space required to the management of variation type, a space share of supplemental areas for learning activities and movement, had shown comparatively low share before remodeling, was improved to 6% and 11.6%, respectively. However, the spacial share of two areas were 16.8% and 12.9%, respectively, in the schools of Japan and it meant the distribution of area was more even than the cases of our country.

The amount of multi-aged housing more than 15 years since the completion has increased, and the real estate market caused by apartment remodeling has also increased. The domestic mortgage loan regulation on relocation expense caused by remodeling apply to same limit as that for mortgage loan newly-built apartment. The excessive government housing regulation could be an obstacle for the occupants residential stability of remodeling apartment. To suggest methods for government housing regulation of residential mortgage loan related to remodeling, examples for mortgage loan regulation and mortgage products were studied and compared. It is pointed out that regulation on occupants relocation expense caused by remodeling has to be relaxed and mortgage product development are needed to boost remodeling project.

Regional relocation of population in Korea is required strongly from natural and environmental sides for substantial growth of economy and the rigorous revival national economy against especially internationalization. This paper aimed for analysed the population distribution by regional and special characteristics of the inter-migration and showed the direction of population policy through the model building. Relocation methods of population by region has been examined through the process from the approach method by Haurin's production function to the approach by the utility function. The examination of the development model is done efficiently, how utility these approach models are depends on that scientific and composite plan for population problems against forced policy should be taken precedence.
