γ-dicalcium silicate (γ-C2S) is characterized by its strong carbonation reactivity and has the prospect to be utilized as a building material with the added benefit of CO2 capture. This paper aims to point out the impact of γ-C2S on the microstructure characteristics and mechanical properties of GGBFS paste, and mortar samples. Three curing conditions including un-carbonation, natural carbonation, and accelerated carbonation were applied to the research. Besides, hydration products after the carbonation process are also detected. What's more, the carbonation treatment method also meets the requirement of capture more greenhouse gas and recycles the waste products of metallurgy.

Purpose: To explore the application prospect of support vector machine (SVM) in supply chain management and its practical application in supply chain performance evaluation practice. Research design, data and methodology: This paper establishes the performance evaluation index system of supply chain management according to the balanced scorecard (BSC) theory, and establishes the SVM model of supply chain management performance evaluation based on the SVM principle. Results: The performance evaluation results of the supply chain of an electric power equipment Co., Ltd. in Harbin established by using the model are consistent with the actual situation, which indicates the nature and accuracy of the possible reflection of the established supply chain performance evaluation model. Conclusions: The results show that SVM model can be used to evaluate enterprise supply chain management performance indicators, and can improve enterprise supply chain management performance, thus demonstrating the effectiveness of the model.

With rapid changes taking place in every field, the expansion and specialization of various social service activities are one of the characteristics of the modem society. However, the increase of crimes and inefficiency of public police service to cope with this situation have caused discontent and distrust on the service among the public, making people more inclined to solve safety-related problems by themselves. Private Security Service(PSS) and Private Investigation Service(PIS) were introduced to satisfy these needs. In the area of PIS, Public Investigation Service System(PISS) has been established for a quite long time in foreign countries. However in Korea, PIS is being provided by unregulated service providers such as errand service center due to the lack of legal system, causing many problems related with illegal practices by the service providers. This paper is the result of the research on how to adopt a relevant PISS in Korea and develop it in the future. This kind of research is much needed to curb the rising illegal practices of the errand service centers, complement the insufficient operation of public police service, and strengthen the competitiveness of our country by taking more efficient actions in the changing public security environment. Based on the research, this paper also examines positively the possibility of introduction of PIS in Korea. This paper also recommends a prompt enactment of PIS regulation and improvement on the legal environment for such introduction of the relevant and suitable PISS in Korea.

Local universities are faced with rapid environmental changes in 2000's. Therefore local universities are required to research for more specialized marketing strategy such as positioning strategy. The objectives of this study are to examine what are the most important university images and image position of 7 universities'. In order to this study, 276 questionnaires collected from university in Busan area are analyzed by t-test, anova. The results of this study are summarized as follows (1) the most important university images are ranked in the order 1) prospect of getting employment(4.78), 2) possibility of development (4.35), 3) confidence(4.31), 4) research ability(3.97). It is true that practical images get high grade, traditional image such as research ability remains yet as a very import image. (2) Except (A, F) & (B, E) university, common position is not found among the 7 universities, therefore each university cultivate important image as G university dose. (3) Private university are underestimated by student of national university. There is a necessity for cultivating and promoting private university images. (4) Students of private university, particularly students of F university, overestimated their university images seriously.

이 글은 국내 기록관리 학술논집에 발표된 논문을 정량적, 내용별 분석을 통해 기록물 평가론 연구동향을 파악하려 했다. 정량적 분석에서는 논문 게재 시기와 연구자 정보가 주요한 분석도구였으며, 내용적 분석은 해외 이론에 대한 소개와 현실 적용, 기록물 보유일정표에 해당하는 기록물분류기준표, 기록관에서의 재평가, 민간기록물 평가의 4개 주제로 나누어 진행했다. 전체 33개 논문을 분석한 결과, 평가를 주제로 한 논문의 수가 줄어들고 있으며 기록관리 실무를 담당하는 연구직의 참여가 크게 줄어들었고, 내용적으로도 현재 기록물 평가에 대한 문제점 지적이나 대안 제시와 같은 논의가 감소했음을 알 수 있었다. 향후 이론과 실무의 조응을 통해 평가 영역의 활성화와 다양한 기반 확대가 필요하다는 점을 강조했다.

At present, an acoustic Doppler current profiler (ADCP) is one of the most suitable tools for measurement of three dimensional flow characteristics in the river. The data resulting from this approach can be used for flow visualization and velocity mapping together with post-processing software tools. Among them, 'adcptools' is the latest one and provides more realistic velocity distribution in the cross-section since it uses velocity along the beam direction. In this study, a flow analysis was made using the 'adcptools' for the Amazon River and the Han River dataset. Discharge was recalculated and accuracy of discharge and velocity was evaluated. Streamwise velocity distribution and secondary flow pattern in cross-sections were visualized. Geo-referenced velocity distribution was also mapped. A summary with future prospect of 'adcptools' for studies on fluvial geomorphology is briefly given.

The development of Internet technology can affect firm value through the use of social media by business people. Nowadays, social media affect businesses of all sizes in several different ways. Despite the various benefits obtained by using social media, research at the organizational level and its impact on business performance have not grown as fast as desired. This research aims to examine the effect of social media on oil and gas firms' value. The research sample consists of 9 oil and gas firms listed on the Indonesian Stock Exchange 2013-2018. Social media proxies are firms' social media, other social media mentions, and social media sentiment. Firm value is measured by the market value to assets ratio. Data analysis uses a random-effect regression test. Based on the analysis, the social media account of a firm has a positive effect on firm value. It indicates that social media give advantages for oil and gas firms to give a signal of business prospect, make use of opportunities related to industry alliances, recruit employees globally, and c. On the other hand, the positive sentiment on social media has no effect on oil and gas firms' value.

The research in the literature review on Internet of Things (IoT) adoption from an individual consumer viewpoint is minimal and has not yet been fully investigated. Therefore, the objectives of this study are to analyze the growth of IoT in recent years and to conduct a weight analysis of the factors that affect acceptance intentions and real usage of IoT-enabled services. For the review, we analyzed 87 publications from 13 conferences and 54 journals published during the period 2014-2020 about consumer adoption of IoT. Following the study, we discovered an unprecedented increase in the number of articles published in the last seven years, which points to an emerging area with an enormous prospect. Furthermore, the weight analysis outcome was associated with the diagrammatic representation in this study. After that, this research developed a generalized consumer IoT adoption model based on the 12 best predictors derived from frequency count and weight analysis, which had the highest predictive power for calculating IoT adoption. This paper further acknowledges the study's theoretical and practical contributions, as well as its shortcomings, and proposes further research directions for future researchers.
