오늘날 점차 데이터 집약적으로 변모하는 학문 환경 속에서 데이터는 연구부산물이 아닌 연구성과물로써 학술 커뮤니케이션의 기반으로 자리 잡아가고 있다. 그러나 데이터 공급의 확대나 접근가능성의 확보만으로는 실제적인 데이터 재이용을 담보하는데 한계가 있다. 이를 극복하기 위해서는 학술연구자의 데이터 재이용 행위와 데이터요구를 심층적으로 파악할 필요성이 있다. 따라서 본 연구는 연구자의 주요 데이터 재이용 행위와 데이터요구를 규명하고자 하였다. 이를 위해 한국사회과학자료원(KOSSDA)의 최근 3개년 데이터 재이용문헌 중 KCI 등재 논문의 저자를 연구대상으로 선정하고, 인터뷰를 수락한 연구자 12명과의 심층면담을 수행하였다. 심층면담 분석결과, 데이터를 재이용하는 요인은 개인적, 경제적, 기술적, 사회적 측면 모두에서 나타났으며, 데이터 재이용 목적에 따라 데이터 그 자체를 이용하거나 데이터가 지닌 맥락정보를 활용하였다. 웹 기반의 정보원으로부터 데이터를 주로 습득하였으나 비공식적인 커뮤니케이션을 통해 파악하는 경우도 있었다. 한편 데이터 재이용 시에 발생하는 학술연구자의 데이터요구를 살펴보면 생산 단위는 기관을, 언어는 영어를, 국가로는 미국을 선호하였다. 또한 조사원 기입식 대인면접 조사 방식으로 수집된 양적 데이터를 우선시하였다. 메타데이터와 식별정보를 충분히 포함한 원자료 수준의 데이터를 긍정적으로 인식하였으나, 접근 및 이용이 통제된 데이터는 데이터가 지닌 가치에 대한 확신을 갖기 어려워 부정적으로 받아들였다. 그러나 데이터의 규모나 최신성과 관련된 선호는 뚜렷하게 나타나지 않았는데 이는 선택 가능한 유사 데이터가 부재하였기 때문이었다.

The extensive growth in data rate demand by the smart gadgets and mobile broadband application services in wireless cellular networks. To achieve higher data rate demand which leads to aggressive frequency reuse to improve network capacity at the price of Inter Cell Interference (ICI). Fractional Frequency Reuse (FFR) has been recognized as an effective scheme to get a higher data rate and mitigate ICI for perfect geometry network scenarios. In, an irregular geometric multicellular network, ICI mitigation is a challenging issue. The purpose of this paper is to develop distributed dynamic power allocation scheme for FFR based on game theory to mitigate ICI. In the proposed scheme, each cell region in an irregular multicellular scenario adopts a self-less behavior instead of selfish behavior to improve the overall utility function. This proposed scheme improves the overall data rate and mitigates ICI.

정보 기술의 발전으로, 공유 경제 서비스는 새로운 형태의 소비 방식으로 자리 잡았다. 특별히 차량을 소유하지 않고 빌려 쓰는 형태인 카 셰어링은 개인들의 이동 수단의 범위를 확장하는 새로운 서비스이다. 차량 소유로 발생하는 비효율성을 줄이고, 교통 문제를 완화하는 등 카 셰어링은 다양한 사회적 이점을 제공하지만, 이를 구현하기 위해서는 개인의 카 셰어링 서비스 이용 패턴을 이해하고 이용자의 서비스 재사용을 유도해야 한다. 본 연구는 개인의 카 셰어링 서비스 재사용 행동을 이해하기 위해 RFMC (Recency, Frequency, Monetary, and Clumpiness) 모델을 활용하였다. 국내 카 셰어링 서비스 업체의 데이터를 분석한 결과, 카 셰어링 서비스 재사용에 Recency, Monetary 는 부의 영향을, Frequency는 정의 영향을 끼치는 것으로 나타났다. 더욱이 Clumpiness가 높은 집단의 경우, Recency와 Monetary의 효과는 두드러지는 반면, Frequency의 영향은 미미해졌다. 이러한 연구 결과를 바탕으로, 이론적, 실무적 함의를 도출하였다.

This study examined how middle-aged female consumers' environmental consciousness influences their attitudes and ethical purchasing behavior toward RUR (recycling, upcycling, and reuse) knit products. The research employs a survey method, targeting 30-40 year old women residing in Seoul and Gyeonggi-do Province. On-line and off-line data collection were conducted. The following conclusions emerged through statistical analyses, including factor analysis, cluster analysis, t-test, and regression analysis. Firstly, respondents' environmental consciousness variables were classified into two factors, delineating high and low environmental consciousness clusters, demonstrating significant differences between them. Secondly, the high environmental consciousness cluster exhibited more positive consumer attitudes and ethical purchasing behavior towards RUR knit products. Moreover, it was established that environmental pollution consciousness and eco-friendly product purchase consciousness influenced environmental consciousness on consumer attitudes and ethical purchasing behavior. Lastly, the study confirmed that consumer attitudes mediated environmental consciousness and ethical purchasing behavior. In conclusion, this research establishes a meaningful link between environmental consciousness, consumer attitudes, and ethical purchasing behavior in 30-40 year old women. Environmentally conscious groups positively influence attitudes toward RUR knitted fashion and promote ethical purchasing behavior. Consequently, it is recommended that knit fashion companies prioritize environmental consciousness and eco-friendly products in their marketing strategies. Furthermore, diversifying the application of RUR knit products, coupled with eco-friendly production techniques, can amplify their appeal and utility, ensuring a positive impact on consumer behavior.

Unsafe behavior is one of the major causes of construction accidents. Managing the behavior of workers in real-time is difficult and requires huge manpower. In this paper, a new real-time locating framework is proposed to improve safety management by collecting and analyzing data describing the behavior of workers to identify habits that may lead to accidents. The aim of the study is to identify working habits of workers based on their location history. Location data is used to compare with that of other workers and equipment. The results indicate that the reuse of real-time location data can provide extra safety information for safety management and that the proposed system has the potential to prevent struck-by accidents and caught-in between accidents by predicting unwanted interaction between workers and equipment. This adds to current research aimed at automating construction safety to the point where the continuous monitoring, managing and protection of site workers on site is possible.

In this paper we introduce the Internet-based purchase support systems using data mining and case-based reasoning (CBR). Internet Business activity that involves the end user is undergoing a significant revolution. The ability to track users browsing behavior has brought the vendor and end customer's closer than ever before. It is now possible for a vendor to personalize his product message for individual customers at massive scale. Most of former researchers, in this research arena, used data mining techniques to pursue the customer's future behavior and to improve the frequency of repurchase. The area of data mining can be defined as efficiently discovering association rules from large collections of data. However, the basic association rule-based data mining technique was not flexible. If there were no inference rules to track the customer's future behavior, association rule-based data mining systems may not present more information. To resolve this problem, we combined association rule-based data mining with CBR mechanism. CBR is used in reasoning for customer's preference searching and training through the cases. Data mining and CBR-based hybrid purchase support mechanism can reflect both association rule-based logical inference and case-based information reuse. A Web-log data gathered in the real-world Internet shopping mall is given to illustrate the quality of the proposed systems.

The purpose of this study were to examine the disposal consciousness of foods waste and meal management behavior related to environmental conservation, and to find out the ways to improve the disposal of foods waste. Data were collected from questionaire with 786 housewives who live in Chonbuk area. About 45% of foods waste consisted of vegetables and fruits. The levels of cooking(use) and idsposal behavior among meal management behavior were relatively high, but food preparation(buy) score was low. These results suggested that menu planning before food preparation, and buying some cleaned and trimmed foods in the market should be recommennded to reduce the foods waste. The levels of meal management behavior did not show any significant associaations with disposal consciousness of foods waste but were positively correlated to environmental conciousness. It could be thought that the effort of government administration to reduce and reuse of foods waste is needed to improve the desirable disposal behavior of that, and the well programmed enviornmental education should be more required and practical than increase the environmental conciousness.

Due to the rapid expansion of fashion, consumers easily purchase fashion products, the period of wearing apparel is shortened, and the occurrence of clothes piling up in the closet is increasing. In order to induce and suggest rational consumption and disposal actions, research focused on the factors influencing difficulty discarding and disposal behavior toward a fashion product is needed. Thus, this study considered fashion-shopping orientation as a variable affecting difficulty discarding and disposal behavior toward fashion products. A total of 325 questionnaires were collected, and 11 were discarded due to partial responses or missing data. Finally, a total of 314 survey questionnaires were analyzed. Frequency, exploratory factor, reliability, and multiple regression analyses were employed for data analysis using SPSS 23.0. The study results were as follows. First, hedonic and economic shopping orientation positively affected difficulty discarding a fashion product, whereas rational shopping orientation negatively affected difficulty discarding a fashion product. Second, hedonic, economic, and conspicuous shopping orientation positively affected reuse behavior among disposal behavior toward a fashion product. Third, trend-seeking and convenient shopping orientation positively influenced handover behavior. Fourth, economic and conspicuous shopping orientation positively affected separation discard behavior. The results of this study provide various guidelines for manufacturers and retailers of fashion products.
