In a situation where there are multiple diverse datasets, it is essential to have an efficient method to provide users with the datasets they require. To address this suggestion, necessary datasets should be selected on the basis of the relationships between the datasets. In particular, in order to discover the necessary datasets for disaster resolution, we need to consider the disaster resolution stage. In this paper, in order to provide the necessary datasets for each stage of disaster resolution, we constructed a disaster type and disaster management process ontology and designed a method to determine the necessary datasets for each disaster type and disaster management process step. In addition, we introduce a method to determine relationships between datasets necessary for disaster response. We propose a method for discovering datasets based on minimal relationships such as "isA," "sameAs," and "subclassOf." To discover suitable datasets, we designed a knowledge exploration model and collected 651 disaster-related datasets for improving our method. These datasets were categorized by disaster type from the perspective of disaster management. Categorizing actual datasets into disaster types and disaster management types allows a single dataset to be classified as multiple types in both categories. We built a knowledge exploration model on the basis of disaster examples to ensure the configuration of our model.

This study examines the actual state of using digital convergence products by consumers, and analyzes the expectation that consumers have regarding digital convergence products and the actual satisfaction of the digital convergence products. In addition, it analyzes factors affecting the satisfaction with digital convergence products. First, mobile phones, which 99.4% of those surveyed had, cameras, which 90.6% had, and mp3s, which 71.8% had, were found to be necessities. Second, the ratio of owning digital convergence products was 79.5%, 48.1%, and 52.4%, respectively. In the case of a mobile phones, a digital convergence type is already common. Third, regarding the reason for purchasing digital convergence products, they chose convergence products because there was no product with a simple function that they wanted to have: 38.2% in terms of a mobile phone, 47.2% for a camera, and 28.2% for an mp3. This shows that a consumer's choice was infringed in a great deal at the back of remarkable quantitative growth in digital convergence products. Fourth, the analysis of the factor regarding the consumer's expectation on digital convergence products showed 3 kinds of factors, i.e., expectation of benefit, expectation of risk, and expectation of situation. Fifth, as a result of analyzing the structural model regarding the effect on satisfaction by a consumer's expectation and the outcome on digital convergence products, all the expectations and outcomes of benefit, risk, and situation did not have a direct effect on satisfaction. Only an indirect effect through inconsistency showed a statistical significance.

건설공사 계약에서 공기연장 시에는 계약당사자의 귀책에 따라 지체상금의 부과 내지는 연장비용을 지급토록 규정하고 있으나, 그 이행에 있어 당사자의 정량적 귀책구분 등 분석결과에 의해 전형적으로 이행되는 경우는 거의 없다고 할 수 있다. 결국 이는 수행참여자의 계약적 의무이행에 대한 책임회피이며, 향후 잠재된 공기연장클레임 등 더 많은 시간과 비용을 지불해야 하는 분쟁으로 비화될 것은 자명하다 할 것이다. 그 원인으로는 현행의 CPM 네트워크공정표에 의한 공정관리 방법 이 수동적이고 사후적 인 관리로서 공기 연장이 발생한 후, 그 사유 및 기간의 책임분석을 통한 관리로 그 한계성으로 인하여 연장예방 및 클레임해결이 불가능한 것이다. 따라서 본 연구에서는 현행 계약자들의 공정관리 수준을 고려하고, 공기연장의 핵심이라 할 수 있는 연장사유에 대한 사전관리를 통한 프로세스 접근방식(Process Approach)의 공기연장사유 관리모델을 제시하여 프로젝트 수행 당사자의 책임의식 고취와 책임관리, 사전관리, 증거관리를 능동적으로 수행 가능할 수 있게 하여, 공기 연장예방 및 당사자의 원만한 클레임해결을 위한 관리기준 모델을 제시하는 것이다.

This study is to survey the materials purchasing and inventory management status and the characteristics and opinions of the staff in charge of purchasing and inventory of the general hospitals in Busan area in order to contribute to the rationalization of its management through the grasp of actual situation and the presentation of desirable improvement plan for the materials purchasing and inventory management. The status of medical institute had been surveyed by the purchasing/ administration managers of total 26 general hospitals, and the purchasing/ management questionnaires had been commenced with 86 staff of the 26 hospitals. Its major survey results, after the analysis of 24 medical institute statuses (return rate of 92.30%) and 60 staff questionnaires (return rate of 69.76%), are as follows. First, post-purchasing evaluation system is not used actively, orders are being placed by phone or fax, and general merchandise is being purchased through free contracts in most of the hospitals participated in the survey. Second, as per the materials supplying methods, the requisition and delivery system is currently the most popular in the hospitals surveyed, however, both the requisition and delivery system and the par level transfer system are the most desired in the hospitals of more than 500 beds, and the par level transfer system is the most desired in the hospitals under 500 beds for the materials supplying system in the future. Third, as per the inventory management system that is desired the most in the future, the SPD and JIT types are preferred in the hospitals of more than 500 beds, the stockless strategy is preferred in the hospitals under 500 beds, the senior staff above section chief grade prefer the stockless strategy, and the junior staff prefer the ABC classification and SPD types. Fourth, The necessity of purchasing staff's training for the materials management is highly recognized but the effectiveness is not so much acknowledged, which is because such a training is thought to be so superficial and formal that it is not helpful much in the actual field. When summarizing the survey results as above, the materials purchasing and management system is differed for each group of hospitals according to the size of beds, and the more scientific management system is largely required by the general hospitals in Busan city. They also hope the introduction of joint purchasing system, materials management by the bar-code system, and positive execution of the market survey and training of the relevant staff for the management of purchasing affairs. So the more systematic purchasing and inventory management is regarded to be necessary through the introduction of scientific and specialized education of materials management, market survey, and post-purchasing evaluation system also through the computerization of materials purchasing and inventory management as soon as possible.

The death rate in the construction industry, which is more than twice that of other industries, increases the need to solve chronic safety problems. In a situation in which the safety management measures that have been maintained thus far are unable to reduce construction accidents, the introduction of smart construction safety technology (SCST) that reflects the 4th industrial technology is required for the safety management of workers. Large corporations or public institutions have introduced SCST and are operating pilot sites, but SCST is still in its infancy and there have yet to exist field data regarding necessity and effectiveness. In this study, the concept of SCST, which has still to be established, is defined, and the actual condition of SCST was analyzed through a survey. Through the analysis of the necessity of SCST introduction, convenience, and effectiveness before and after its application, problems such as problems from the field point of view as well as other factors hindering the introduction of such technology are derived in detail. In addition, an effective combination of technologies for safety management at the current level is determined and an activation plan is presented.
