The purpose of this study is to survey fundamental limitations and problems of sports event hosting from the critical point of view and to set future-oriented perspective. The reason and legitimacy for hosting sports event have come from pragmatism based on ideological logic behind politics. Thus, the flow of advanced studies was mostly limited to the category of efficiency. However, there is fundamental limitation in sports even hosting in terms of its financial expectation and efficiency. Critical approach will contribute to minimizing side effects caused from blind acceptance through awakening dispassionate and realistic judgment. In addition, rational selection of sports even hosting can be achieved through interconnection of sports culturism's directivity as an advanced sense of sports culture, integrated perspective that penetrates problems of growth and distribution and local governance as apolitical philosophy, and of course, through concentration of energy.

Quantum-dot cellular automata(QCA) is a computing model designed to be similar to cellular automata, and an alternative technology for next generation using high performance and low power consumption. QCA is undergoing various studies with recent experimental results, and it is one of the paradigms of transistors that can solve device density and interconnection problems as nano-unit materials. An XOR gate is a gate that operates so that the result is true when either one of the logic is true. The proposed XOR gate consists of five layers. The first layer consists of OR gates, the third and fifth layers consist of AND gates, and the second and fourth layers are designed as passages in the middle. The half adder consists of an XOR gate and an AND gate. The proposed half adder is designed by adding two cells to the proposed XOR gate. The proposed half adder consists of fewer cells, total area, and clock than the conventional half adder.

Big data research plays a role of supplementing existing social science research methods. If the survey and experimental methods are somewhat inaccurate because they mainly rely on recall memories, big data are more accurate because they are real-time records. Social science research so far, which mainly conducts sample research for reasons such as time and cost, but big data research analyzes almost total data. However, it is not easy to repeat and reproduce social research because the social atmosphere can change and the subjects of research are not the same. While social science research has a strong triangular structure of 'theory-method-data', big data analysis shows a weak theory, which is a serious problem. Because, without the theory as a scientific explanation logic, even if the research results are obtained, they cannot be properly interpreted or fully utilized. Therefore, in order for big data research to become a methodological innovation, I proposed big thinking along with researchers' efforts to create new theories(black boxes).

The purpose of this study is to investigate the causality between life satisfaction and domain satisfactions. For this study, data were collected from 207 respondents. They completed World Health Organization Quality of Life Assessment Instrument - Brief (WHOQOL-BREF) which is self-report questionnaire asking about life satisfaction and domain satisfactions. For data analysis, the verification procedure by autoregressive crosslagged modeling of structural equation was used. The analysis results of measures showed the causal relation between the two variables, that is, domain satisfactions acted as cause of life satisfaction. There were discussions on the issues about the analysis method of the autoregressive crosslagged modeling, the implications of the results, and the limits of the research. This study ascertained the intervention direction between life satisfaction and domain satisfactions to promote life satisfaction.

The purpose of this study is to analyze the relationship between social change and ritual change and to reveal the differences between Confucian funeral rites and modern rituals based on that relationship. In addition, we attempted to examine the process of change in rituals over time in connection with changes in institutions. The periodization of funeral rites was analyzed by dividing them into the pre-modern 'Confucian funeral rites', the 'modern funeral rites' during the Japanese colonial period, and the 'modern funeral rites' based on ritual capital with the implementation of the Healthy Family Rituals Standards in 1999. In addition, the understanding of the rites of the times must be understood through the process of moving from pre-modern to modern funeral rites and modern funeral rites, escaping the logical contradiction of succession of tradition through division of time. This study is meaningful in considering that Koreans' perception of death continues to reflect the times from the perspective of change and continuation of rituals.

Appraisal in electronic record environments is performed focusing on not content but function in which the records are created. Functional appraisal is practically supported in that electronic records composed of 0 and 1 of the bit-stream is unable to be evaluated individually. But the most important reason functional appraisal is performed in electronic record environments is that functional appraisal can select electronic records which assure business context and recordness, and need to run organization and perform business. In Korea, functional appraisal has adopted in course of renovation of national record and archive management system, but methods and logics of functional appraisal have numerous problems. To do so, this article discusses current appraisal system and methods of korea which has renovated confronting with electronic record environments, and then proposes the improvement directions on appraisal system and methods of Korea in electronic record environments from the perspective of long-term views. In this respect, this article proposes the improvement directions on current appraisal system and methods of Korea as follows. First, business functional analysis of each agency in functional appraisal should greatly strengthen. Second, it is necessary to devise proper methods for selecting primary values at current stage of electronic records, and to reinforce appraisal of records as knowledges and informations. Finally, functional appraisal, which inevitably carries out for appraising electronic records, has defects in aspect of selecting archives important in a national point of views. Therefore this article suggests the necessity of archival appraisal strategies that complement functional appraisal. This appraisal system is able to establish a base of the regime of archival appraisal which will harmonize primary value at current stage with secondary value at non-current stage in a national point of views.

In this paper, collecting real-time data frames that occur during RS232 communication between an HMI and PLC of automation equipment by sniffing real-time information data frames through MCU without modification of the HMI or PLC, a method is proposed that allows users to collect data without being dependent on the modification of PLC and HMI systems. The user collects necessary information from the sniffing data through the parsing operation, and the original communication interface is maintained by transmitting the corresponding sniffing frame to the destination. The MCU's UART communication interface circuit is physically designed according to the RS232 communication standard, and this additionally improves efficiency more so than an interrupt-based system by using the DMA device inside the MCU. In addition, the data frame IO operation is performed by logically separating the work of the DMA interrupt service routine from the work of the main thread using the circular queue. Through this method, the user receives the sniffing data frame between the HMI and PLC in RS232 format, and the frame transfer between PLC and HMI arrives normally at the original destination. By sniffing the data frame without further modification of the PLC and HMI, it can be confirmed that it arrives at the user system normally.
