This study evaluated the psychometric properties of the revised Korean version of the Anxiety Control Questionnaire (revised K-ACQ) among 508 outpatients with DSM-IV anxiety and mood disorders and 469 non-clinical participants. Exploratory factor analyses produced a 3-factor solution based on 19 of the ACQ’s original 30 items. Confirmatory factor analysis of an independent clinical sample replicated the hierarchical 3-factor solution. Multiple-groups CFA indicated that the measurement properties of the revised K-ACQ were invariant in clinical and nonclinical samples. We discussed these results with regard to their conceptual and psychometric implications for the construct of perceived anxiety control.

Purpose: The purpose of this study was to identify the correlation between the motivations to use social media and self-control among female middle school students. Methods: This study is a cross-sectional descriptive study. To collect the data, 300 female students of S and E middle school in S city responded to a self-administered questionnaire asking about their motivation for social media use and self-control. The data were analyzed through descriptive statistics, independent t-test, one way ANOVA, Scheffé test, Pearson's correlation, and stepwise multiple regression, using the SPSS/WIN 21.0 program. Results: The average time spent on social media was 3.70 hours. The mean scores of social media usage motivation and self-control were 48.15 and 58.47, respectively. The more average time spent on social media, the higher was the motivation to use social media. The scores of motivation to use social media were higher in students with low satisfaction of their school and family life. Students with low satisfaction of their school life had higher scores in some subcategories of self-control; preference to simple task, egocentrism, and stroppiness. Motivations to use social media showed a significant positive correlation with self-control. Self-control was affected by motivations to use social media and this variable explained 11.6% of self-control among female middle school students. Conclusion: The results of this study suggest that we should develop programs which help improve students’ self-control and prevent the side effects of social media use among female middle school students.

The current paper proposes fast distributed constrained power control (FDCPC) with a non‐stationary relaxation factor as the next power update for CDMA cellular power control systems. A review is also given of unconstrained control algorithms: distributed power control (DPC), unconstrained second‐order power control (USOPC), and DPC with a stationary relaxation factor (DPCSRF). To improve the performance of outage probability convergence, DCPC with a non‐stationary relaxation factor (FDCPC) is proposed. Under constrained conditions, the convergence rate of FDCPC is shown to outperform that of DCPC and constrained second order power control(CSOPC).

본 연구는 Delphi 및 DEMATEL 기법을 활용하여 참여정부의 전시작전통제권(이후 전작권) 전환에 관한 정치․군사적 결정요인을 선정하고, 이들 결정요인간의 영향정도 및 관계를 정량적․정성적으로 분석하는데 있다. AHP를 활용한 기존연구에서는 전작권 전환 결정요인을 학술자료와 현장실무경험을 바탕으로 선정하여, 요인선정에 대한 보다 객관적인 분석이 요구되었다. 본 연구를 위해 온라인 및 오프라인 환경에서 안보 관련 전문가 집단을 대상으로 일련의 설문을 실시하였다. 분석결과로 참여정부의 전작권 전환 결정요인은 크게 ‘군사주권의 회복', ‘평화통일을 위한 여건조성', ‘우리나라의 국력신장에 따른 국격 제고'로 AHP기법에 의한 기존연구와 대동소이하였으며, 전작권 전환 결정요인간의 영향 및 관계는 ‘군사주권 회복'과 ‘평화통일을 위한 여건조성'은 별개 사안으로 상호 연관성이 없고 ‘군사주권 회복'이라는 진보세력의 정치적 이익이 주된 결정요인이었던 것으로 나타났다. 본 연구는 Delphi 및 DEMATEL 기법을 적용하여 참여정부의 전작권 전환 결정요인에 대해 정략적․정성적 분석을 실시하였는데 의의가 있다.

This study selects political and military decision factors of Participatory Government's Wartime Operational Control(OPCON) Transition and analyzes, both quantitatively and qualitatively, the effects and relations between those factors. Previous research utilizing the Analytic Hierarchy Process(AHP) selected their decision factors based on academic data and field experience, requiring more objective analysis of the factors. For this study, we conducted a survey among security subject matter experts(SME) both online and offline. The results show that OPCON transition's decision factors were to ‘recover military sovereignty', ‘set the conditions for peaceful reunification' and ‘improve ROK image through enhancing national power' which differs little from the previous AHP method studies. It also showed that ‘recover military sovereignty' and ‘set the conditions for peaceful reunification' had no relationship to each other and that the key factor that decided the OPCON Transition was actually ‘recover military sovereignty' which represents the interest of the liberal party in ROK. This study finds its meaning by analyzing the decision factors of Participartory Government's OPCON Transition thorugh Delphi and DEMATEL method.

The countless advantages of cloud computing has brought a massive change to the lifestyle and the way to cope with the world today, yet the cloud has to reach maturity. However, the main barrier to its widespread adoption is the security and privacy issues. In order to create and maintain mutual trust among the customers and the cloud service providers, a well – defined trust foundation should be implemented. The data stored in the cloud remotely by individual customer or an organization, so they lost control over the data, thus creating a security dilemma. The most challenging and hot research area in cloud computing now a day is the data security and access control. An effective measure to protect cloud computing resources and services in the start is to implement an access control mechanism. In this paper the features of various access control mechanisms are discussed and a novel framework of access control is proposed for cloud computing, which provides a multi - step and multifactor authentication of a user. The model proposed is well-organized and provably secure solution of access control for externally hosted applications.

In indoor Light Fidelity (Li-Fi) system the position of transmitter and receiver bring different impact on coverage area. Due to Line of sight (LOS) characteristics of Li-Fi, coverage area of a light emitting diode (LED) transmitter plays a vital role for efficient reception of data. In this paper we considered the case when 1 optical receiver can simultaneously receive signal of 2 LED transmitters and present an optimal solution of controlling coverage area of LED transmitter using dimming factor. This paper focuses on efficient reception of data by controlling coverage area of multiple LED transmitters. The performance of proposed dimming factor approach is evaluated by using different dimming based modulation schemes.

With the recent development of IT society, the value of knowledge information has been focused more importantly. However, the accidents of personal and corporate secrets being leaked frequently happen, and also the damage is getting bigger day by day. The important information of individuals and businesses is leaked or processed by outside attacks or personal mistakes, thus misused, and thereby considerable damage is occurring. For this reason, the necessity of how to effectively manage personal and corporate information is emerging. This study intends to suggest a method that can protect servers and media information, which requires security. The access control method suggested here uses a way that grants users authority by grade and authenticates users through Two-Factor Authentication method. This study suggests a way that can reinforce access itself, through Multi-Factor authentication method which falls into users’ grade in EDMS(Electronic Document Management System). In addition, when users have access to documents, it identifies users’ security grade and the related department, thus limiting the access to the related documents and media. Through the method suggested in this study, we can control access effectively and safely, and can enhance the security of documents and media.

In this paper, an iterative learning control topic for a kind of singular distributed parameter system with forgetting with time-delay which initial value can vary in a little space has been discussed. And a high level algorithm is extended and proven, using Green formula and Gronwall inequality, that it is suitable for the given system. Convergence of the proposed approach is analyzed and the uniform boundedness of tracking error is obtained in this paper. Numerical simulation is presented for a parabolic partial differential equations solved using ILC based on Eular difference format. At present, the application research of ILC method to the singular distributed parameter system with forgetting factor with time-delay is less. So this paper expands the scope of research for singular system and iterative learning control. Numerical example is given to illustrate the effectiveness of the proposed method.

MITF (microphthalmia-associated transcription factor), a bHLH (basic helix-loop-helix) transcription factor with a leucine zipper, is a key regulatory protein for the pigmentation process in melanocytes. Binding of MITF to E-box caused transcription of several pigmenting genes, including the tyrosinase gene. The purpose of this study is to analyze the interaction of MITF and its DNA binding site (E-box, CATGTG) by surface plasmon resonance. Label free DNA-protein interaction assay, SPR (surface plasmon resonance) was used to analyze their interactions on the gold surface. It is expected that SPR can be a useful method to study of MITF and E-box interactions. We are looking forward to applying this study as a screening tool for depigmenting agents in the cosmetic industry.
