2014년 우리나라 선용품 시장의 규모는 5조 7천400억 원 정도로 추정된다. 대부분이 부산, 울산 등 부산권에서 이뤄지지만 관련업체가 400여 개나 난립해 대부분 평균 매출이 20여억 원으로 영세한 수준이다. 또한 세계 해운항만산업의 불황과 중국을 비롯한 개발도상국들의 저가 선용품의 생산 및 공급으로 인해 국내 선용품 업계가 그다지 밝지 않는 상황이다. 이렇듯 영세한 선용품 산업을 발전시키기 위해서 부산시에서는 부산항국제선용품유통센터 내에 공동물류(창고)를 운영을 제시하였으며 이를 세부적으로 파악하기 위해 성공적 방안 요인 16개의 도출하여 AHP와 IP분석을 사용하여 전략적 방안을 제시하였다.${\cdots}$ (중략) ${\cdots}$.

Purpose: The purpose of study was to identify problems in disaster recovery resource management and operation through on-site investigation and utilize them as improvement proposal for disaster recovery resources management by local governments. Method: Areas with high natural and social disasters recorded in historical and yearly records of natural and social disasters, related books, and annual reports for 20 years were selected. The DRSS data of the selected local governments were analyzed and the reserve warehouse were selected for field survey. Result: It is analyzed that the current situation in the city hall and district offices is somewhat insufficient due to heavy work by the working-level officials of local governments on the storage of disaster recovery resources. The actual amount of stockpiles and DRSS data are somewhat different or missing because the input method and criteria are not clear at present when inputting the current data. Conclusion: To improve the management of the disaster recovery resource reserve, it is deemed that education of DRSS and training of best practices for the operation of disaster management resources are urgently needed, and that a systematic management of stockpiles using disaster prevention experts will be required.

In this study, the effect of repeated traffic vibration on the long-term stability of mine openings is analyzed for re-utilization of abandoned mine galleries. The research mine in this study is an underground limestone mine which is developed by room-and-pillar mining method, and a dynamic numerical analysis is performed assuming that the research mine will be utilized as a logistics warehouse. The actual traffic vibration generated by the mining vehicles is measured directly, and its waveform is used as input data for dynamic numerical analysis, As a results of dynamic numerical analysis, after 20,000 repetitions of traffic vibration, the mine openings is analyzed to be stable, but an increase in the maximum principal stress and an additional area of plastic zone are observed in the analysis section. As shown in the changes of displacement, volumetric strain, and maximum principal stress which are measured at the mine opening walls. It is confirmed that if the repeated traffic vibration is continuously applied, the instability of the mine openings can be increased. Authors expect that the results of this study can be used as a reference for basic study on utilization of abandoned mine.

This study examined the present condition and problems of rural apartment house through documentary survey and considered the social necessity and concept of rural apartment housing. The aim of this study is to suggest the social necessity and spatial composition factor of rural apartment housing. The results of this study are as follows. First, rural apartment houses are generally adjacent to production and natural environments, and tend to be constructed in small complex of 50 households or less with the lack of convenient facilities. Second, the ultimate goal of rural apartment housing plans is to improve the livability, community, sustainability and rurality on the basis of the basic direction of rural areas. Third, it is necessary to install storages within the apt. complex and secure a buffer zone where people can wash their hands before entering the houses. Fourth, rural apartment housing should adopt the space components of auxiliary facilities including storages for agricultural products and farming appliances, common workshops, field attached to home, and washrooms in consideration of the conditions of rural areas different from urban apartment housing.

Performances of common zone with various sizes are examined for possible demand rate variations for an AS/RS. Common zone is a middle area located between the 1st class and the 2nd class to be used by the 1st class Items if the assigned racks are not enough. This area is designed to resolve the rack shortage problem associated with a particular class. In the previous researches, effect of demand rate variation is Ignored since flxed demand rate is assumed. It is found that rack shortage rate is decreased up to 67% of common zone size. However, no difference is found at above 70%. Waiting time tends to be longer with Increased common zone while travel time and throughput are not affected at all with the common zone sloe.

This study aims to analyze the cases of storage space outside housing unit and propose the activation plan. The issue of storage in residential complex has continued to be reported. This is more salient due to the recent preference trend for small houses, the constant increase of living goods and the limitation of the available space inside housing unit. Although more apartment houses are trying to have individual storage in the exterior space to address these issues, there is still a paucity of the related studies and more studies are required. In this study, we conducted on-site investigation and user interview of each case to propose active usage of the storage space outside housing unit. Result of this study shows that the most crucial factor to improve is 'accessibility' in order to activate the storage space. Storage room should be located close to each household or the individual parking space. The second factor is the size and the structure of the storage room. The sufficient space for keeping and taking large objects out are required. The front of the storage room should have a clogged structure to insure privacy. The third is the provision of suitable support programs such as the system that occupants can check remotely what items are in their storage rooms, garage sale, laundry service, auto cleaning system and rental program. Those programs are required for efficient management and activation of space. Another requirement is to improve environmental factors which include maintenance of optimal temperature and humidity, automatic ventilation system, control of individual lights, and security enhancement. Based on the results of the survey, we provide basic data which can be used for practical space planning to activate exterior storage space of the housing unit. Further surveys are required to develop this study by obtaining more data for generalization.

This study examined the present condition of the closed elementary school in the Yeongi province, where much of the area will be transformed into the city of Se-Jong, and suggested the renewal plan in the future. Among the twelve(12) schools, eight(8) that have transferred to private sectors were analyzed in respect to lot size, present usage, surroundings, means of approach, and distance from the most populated area, ect.. Additionally, interview with the management official of school board was taken in place. The findings include: two(2) schools that are located nearer then others to the newly-born city can be rehabilitated as educational facility, such as training institute and cultural experience place. Other six(6) schools can be utilized as senior citizens' center, community center, medical substation, hobby farm, or even community warehouse.

Claesson(2001)'s analytical solution, and two numerical models with Dirichlet and Neuman interior boundary condition respectively were investigated to estimate the transient temperature distribution with distances from the Taejon underground food cold storage pilot cavern. Claesson's solution, which is based on constant temperature boundary condition at the rock wall during a temperature decline step, showed relatively good agreement with temperature measurements in the rock mass in order of average error difference, 0.89$\^{C}$ without any adjustments on laboratory thermal properties to represent the rock mass. For the numerical model with heat flux through the rock wall, a boundary condition setting technique was newly proposed to overcome the difficulty of prescribing variable convective heat tranfer coefficient and far-field air temperature inside the cavern as they may be certainly changed according to the cooling-down time. The results showed also good agreement with measurements in order of average error difference, 1.58$\^{C}$, and were compared to those of the numerical model with fixed temperature at the rock wall. Finally, the most proper procedure to precisely predict the temperature profile around a cavern was proposed as a series of analysis steps including an analytical exact solution and numerical models.
