This study is focused on the residential spaces that the elderly wish to renovate and their willingness to improve residential environment as they grow old. The analysis shows, first, the most inconvenient places as they grow old are the stairs, following by the toilet and the bath. Second, the place that the elderly most wish to renovate is the floor, upgrading floors with non-slippery materials. And they wish to remove the height differences on the floor to protect them from tripping over, upgrade the floor plan for their convenience and renovate the storage and working spaces at the kitchen and dining areas. The more the government supports the costs of the residential renovation service, the more the elderly are willing to use the renovation service. The factors influencing their willingness to residential renovation are health, residential environment, experience to accidents and their allowances. The elderly who experienced accidents inside their residence are more willing to renovate their house. Even though the elderly wish to renovate their houses, it's not carried out due to the financial difficulties and the lack of information. Thus, the government should share the useful information about residential renovation for the safety of the elderly and find a way to raise money to cover the costs of the renovation.

This study attempted to analyze the factors that influence the participation of beneficiary companies in the government's defense industry promotion support project. To this end, experimental data were analyzed by constructing a prediction model consisting of highly important variables in beneficiary company decisions among various company information using the decision tree model, one of the data mining techniques. In addition, various rules were derived to determine the beneficiary companies of the government's support project using the analysis results expressed as decision trees. Three policy measures were presented based on the important rules that repeatedly appear in different predictive models to increase the effect of the government's industrial development. Using the analysis methods presented in this study and the determinants of the beneficiary companies of the government support project will help create a sustainable future defense industry growth environment.

세계무역센터를 대상으로 발생한 9.11.테러 이후 세계 테러 동향은 하드타겟에서 경성타겟으로 점차 변화하고 있다. 경성타겟으로 목표 변화는 테러리스트의 접근성, 대상의 상징성, 미디어 집중성을 고루 갖추고 있어, 테러리스트들의 의사 전달이 용이하기 때문이다. 경성타겟으로 변화와 함께 미디어를 활용한 테러 교육으로 자생테러(외로운 늑대)도 증가하고 있다. 2022년 7월 8일, 일본의 다중이용시설인 나라현 야마토사이다이지 역에서 총기테러 사건이 발생하였다. 야마가미 데스야가 자생테러범은 개조한 사제 총기를 일본 전 총리 아베를 향해 발포하여 과다출혈로 사망에 이르게 하였다. 위 사례는 세계 테러 동향의 변화를 반영한 사건으로, 경성타겟을 목표로 한 자생테러 형태를 보여주고 있다. 본 연구에서는 국내 다중이용시설 테러 발생 시 우선적으로 고려해야하는 고위험 테러유형을 도출하고자, 우리나라와 국가 경쟁력이 비슷한 G7국가의 다중이용시설을 대상으로 발생한 테러사례를 통계적으로 분석하여 테러유형별 위험도를 도출하였으며, 다중이용시설을 대상으로 자행되는 고위혐 테러유형의 위협을 차단하기 위한 테러안전관리 대책의 개선사항을 제언하고 있다.

This paper proposes a fuzzy-based AHP model by which the greenhouse gas reduction for container terminal problem was systematically structured and then evaluated. The model was established by exploiting a fuzzy theory and AHP for capturing the inexactness and vagueness of information. In this study, measurement areas were selected for equipment aspect, operating aspect, and energy aspect. The greenhouse gas reduction is the number one priority in the equipment aspect, operating aspect, energy aspect in order. The analysis result of equipment aspect reveals that the most important element is electrical T/C. The most important element of operating and energy aspect were a container rehandling and a LED lighting. As for the whole priority which conversion weight was applied, the results were shown as follows: an electrical T/C(16.2%) as the first rank: a hybrid Y/T(14.4%) as the second rank: a AMP(10.6%) as the third rank. The result of this study suggests some guidelines for deciding priority of greenhouse gas reduction for container terminal.

A text-based communication system has been developed with a communication function on AIS and display and input function on ECDIS as a way to complement voice communication. It features no linguistic error and is not affected by VHF restrictions on use and noise. The text communication system is designed to use messages for clear intentions and further improves convenience of users by using various UI through software. It works without additional hardware installation and modification and can transmit a sentence by selecting only via Message Banner Interface without keyboard input and furthermore has a advantage to enhance processing speed through its own message coding and decoding. It is determined as the most useful alternative to reduce language limitations and recognition errors of the user and solve the problem of various voice communications on VHF. In addition, it will help to prevent collisions between ships with decrease in VHF use, accurate communication and request of cooperation based on text at heavy traffic areas.

In order to decide the naval ship weapon system acquisition for national policy/market economy activities, the decision makers can determine policy based on current technology level/concentration/utilization. For this, the decision makers apply the major common technology field analysis using patents data. As a method for collecting patent data, we can collect patent data of domestic mobile carriers through the Korea Intellectual Property Rights Information System of Korean Intellectual Property Office. As a result, we collected 14,964 patents/352 International Patent Classification(IPC) types. Based on these data, we performed three analysis processes (SNA, PCA, ARIMA, Text Mining) and got each result from extracting 58 IPC types of SNA and 7 IPC types of PCA. Based on the analysis results, we have confirmed that 7 IPC(B63B, H01M, F03D, B01D, H02K, B23K, H01H) types are the Major Common Technology Distribution of domestic Defense Companies.

Because of their nature as public facilities, demands that former military facilities be utilized for the public welfare are increasing, thereby leading to an increase in cases in which these military facilities are reestablished as parks. Cases in which former military bases were reestablished as public parks were analyzed; as a result, several implications were derived. First, the objectives of public park projects should be examined from the perspective of the concept of urban regeneration and regional revitalization. Moreover, it is necessary that profits are yielded and that regional identity and history are reproduced through reusing existing facilities as much as possible rather than entirely remodeling former military sites. As parks become larger in size, bases should be reorganized into complexes rather than single facilities or programs. It is also necessary that parks be established in stages considering the enormous expenses required for building public parks. Consequently, because the special characteristics of military facilities can lead to insufficient on-site investigation in the process of establishing parks, thereby incurring a vast amount of costs for design adjustment and contamination disposal, this should be considered in advance. A method of delegating the development rights to partial sites to private businesses and supplementing the costs of park establishment and maintenance with development benefits should be examined. In addition, given that there are various interests and stakes in former military bases, a method of operating a public-private cooperative decision-making organization during project execution should be considered. Finally, policies related to urban parks need to be improved in order to raise funds, expand profitable businesses, facilitate social services and sponsorship, and encourage the participation of trusts and non-profit organizations in park operation and management.
