In this paper, we propose a small waste appliance collection system that can be used for efficient waste appliance collection, and implement an unmanned automatic small waste appliance collector system. First, we collected cases related to the collection of waste home appliances, compared and analyzed methods, and arranged the characteristics. We analyzed at the requirements for the collection and management system of waste appliances by dividing it into the aspect of the discharger and the recycling business company. The collection system consists of a client-server structure, which is a collector system and a collection management server. The unmanned automatic collector system is divided into a control unit and a machine/mechanical unit. We identified the functions that the collector system must perform and the hardware required to perform these functions. Based on this, the collector system was implemented as an embedded system. The hardware and software used in the implementation are described and the implementation results are described. The collection system developed in this paper will contribute to the development of urban mining industry by enabling the efficient collection of waste appliances.

The purpose of this study is to propose the importance of responding to the increasing issues related to collection management surrounding school libraries by analyzing the status of collection management policies (CMP) at the school libraries. Accordingly, through literature research, the main contents of the composition of the CMP for children and adolescent users were analyzed. Based on this, a 50 questions questionnaire was conducted and analyzed on the status of the CMP and the composition of the contents of the CMP for 93 school library managers nationwide. As a result, first, the data used as the selecting collections priority selection criteria were curriculum-related and recommended book lists rather than CMP. Second, 31 out of 93 school libraries (33.3%) had with CMP. Third, the understanding and necessity of the CMP of the school library manager with the CMP were higher. Fourth, it was found that more than half of the components of the CMP did not include the renewal cycle, intellectual freedom, etc.

The purpose of this study is to propose established factors and a model of collection development policies for the libraries of theological universities in Korea. To achieve purpose of the study, we analyzed of elements and details of collection development policies at libraries of theological universities in overseas. The study then conducted a survey to understand the current status of collection development policies at libraries of theological universities in Korea. Based on the above results, reflecting both the external and the internal factors, the investigator presented a model of collection development policies by identifying seven elements that should be included when developing the policy: prefaces, collection selection, collection gathering, budget, collection maintenance, mutual cooperation and intellectual freedom, and revision of collection development policies.

This study examines the collection policy of University Archives. The establishment of collection policy enables university archives to concentrate in which memories of university to remain and provide as archives. Accordingly, this study, making a model of university archives in early sage of establishment, intends to investigate the collection policy for collecting archives in university. The first chapter defines the fields and categories of collection of archives. In order to define the collection categories, it outlines the history of the university and set up the fields and categories for documentation. In the second chapter, this study examines about the factors which forms the document of the collection policy, such as a missions statement, a guide to collection, and a guide to acceptance by items. Then, this study, applying items mentioned above, suggests a plan for a collection policy. The model presented in this study may not represent the model of collection policy in the university archives. However, it is meaningful as a study of collection policy and has purpose and significance in making a stepping stone for more developmental collection policy.

We apply VRP(Vehicle Routing Problem) to sludge collection system in this study. Sewage stores of villages are located in each village around a multipurpose dam. Sludge which is produced in sewage store of village is transported from the sewage store of village to the sewage treatment plants by the special purpose vehicle such as the tank lorry. In this paper, we propose sludge collection strategies which allocate each sewage store of village to sewage treatment plants and decide the schedule of sludge collection in order to collect sludge efficiently. The strategies aim to decrease transportation cost with deciding proposed vehicle routing and scheduling the sludge collection. When we decide route of vehicles, we consider the collection time in sewage store of village, distance between sewage store of villages and vehicle information as average velocity of vehicle, operation time of vehicle driver. We also develop the SCMS(Sludge Collection Management System) based on windows system with real data which is used in certain circumstance. And we experiment to figure out vehicle route and transportation cost throughout changing input data.

When construction engineers perform their work in the jobsite, they have to record as-built conditions in the project log (Data Collection). On the other hand, the engineers often have to refer to the construction documents when necessary at the job faces (Data Access). The practice of Data Collection and Data Access in the jobsite can be greatly enhanced by utilizing mobile computing with wireless communications. In this paper, two cases of mobile computing applications for construction field management are presented; Mobile Specifications System and Mobile Data Collection System. The demonstration of the process for developing two mobile applications is the primary purpose of the paper. The problems and issues involved with adopting mobile computing for construction field are also presented. The simple information framework for mobile computing has been also proposed as an outcome of the research. As for development tools, readily available relational database and wireless network have been used. The use of commercial mobile broadband was examined for data communication where local area network is not available.

A collection development policy is the library's master plan that provides library's long/short-term plans. It also informs the community of the library's commitment in collection development. However, in Korea, libraries which maintain such a policy are not yet to be easily found. Furthermore, due to increasing importance of electronic resources, libraries are gradually required to have electronic resource management policy that reflects a change in the information environment. The purpose of this study is to suggest a model electronic resource management policy in academic libraries. It derived and verified more than thirty preliminary elements from literature and case studies. The elements were modified and supplemented, and as a result, the selection criteria gained the highest marks. The findings can be applied for selecting the elements of digital collection development policy in the university library and reorganizing them so as to meet its peculiarities. This study, finally, presents a model that includes a guideline for the university library which will establish digital collection development policy.

In recent years, electronic technologies are rapidly changing the library's approach to collection management. In digital age, collection is a hybrid, that is, a mix of analog materials and digital information resources. But electronic publications are both a blessing and a curse for libraries. And the rapid acceptance of electronic resources raises many misconceptions and myths about their capabilities. This paper analyzes the digital paradox of current collection management from six standpoints : production of digital informations : digital scholarly communication : digital access paradigm : acceptance of e-journal package web collection development : digital archiving. Nowadays the pragmatic view of library is a logical information gateway to its own services and those of other libraries and information providers. Libraries and librarians need a concept and strategies of the hybrid collection management that reflects digital reality.

Refuse collection, one of important elements in reverse logistics, is an activity rendering recyclables or wastes and moving them to some points where further treatment is required. Among various decisions in the collection activity, we focus on network design, which is the problem of locating collection points as well as allocating refuses at demand points to collection points while satisfying the capacity restriction at each collection point. Here, the collection point is the place where recyclables or wastes near the point are gathered, and locating the collection points is done by selecting them from a given set of potential sites. The objective is to minimize the sum of fixed costs to open collection points and transportation costs to move refuses from demand points to collection points. An integer programming model is developed to represent the problem mathematically and due to the complexity of the problem, two types of heuristics, one with simultaneous and the others with separate location and allocation, are suggested. Computational experiments were done on test problems up to 500 potential sites, and the results are reported. In particular, some heuristics gave near optimal solutions for small-size test problems, i.e., 2% gaps in average from the optimal solution values.
