Personalized reminder systems have to identify the user's current needs dynamically and proactively based on the user's current context. However, need identification methodologies and their feasible architectures for personalized reminder systems have been so far rare. Hence, this paper aims to propose a proactive need awaring mechanism by applying agent, semantic web technologies and RFID-based context subsystem for a personalized reminder system, which is one of the supporting systems for a robust ubiquitous service support environment. Rescorla-Wagner model is adopted as an underlying need awaring theory. We have created a prototype system. called NAMA(Need Aware Muiti-Agent)-RFID. to demonstrate the feasibility of the methodology and of the mobile settings framework that we propose in this paper Moreover, to test if the proposed system works in terms of scalability, a simulation was performed and the results are described.

This research was conducted in order to find out the effects of boys' self-control, their parents' behaviors and marital conflict on boys' aggression. Subtypes of aggression in the present research consist of dimensions of the functions and forms (proactive-overt, proactive-relational, reactive-overt, reactive-relational). The participants of this study were 237 boys in the fifth and sixth grades in elementary schools located in Seoul and Gyeonggi province. The questionnaires were derived and modified from Lee Hong (2009) for boys' aggression, from Ju So Young and Lee Yang Hee (2008) for boys' self-control, from Jun Joo Ram (2008) and Heo Seung Yeon (2009) for maternal behaviors and from Kang Na Jung (2008) for marital conflict. In order to grasp the general characteristics of the participants, frequency and descriptive statistics were used. Also, Pearson's correlation was applied to the relationships amomg boys' self-control, marital behaviors and marital conflict on boys' aggression. Lastly, the variables that can predict boys' aggression were analyzed through multiple regression analysis by SPSS 19.0. The major results of this study were as follows. This research showed that this model fit well for boys. To summarize the important results, what is interesting in the present study is the effect of the mother's role in rearing their sons. It was found that mothers' criticism, negative behaviors, and excessive interference can cause boys' high level of aggressiveness. Also, having parents who fight frequently was strongly associated with boys' relational aggression. An interesting finding is that the mother's support influenced boys' reactive-overt aggression. Lastly, boys' self-control was highly associated with boys' proactive-relational aggression. This research may contribute to understanding boys' aggression' subtypes. To that end, the current results suggest that the dimensions of the functions and forms may be a useful tool in an effort to inform developmental theory and intervention. Also, this research may provide guidance for the resolution of problems caused by boys' aggression. Lastly, it was found that self- control training and parental education programs might prove beneficial for helping aggressive boys to overcome their aggressive impulses.

최근 들어 휴대형 무선 기기들의 보급이 확대되고 WiBro/WiMAX/HSDPA 등의 고속 무선 데이터 통신 시스템의 등장에 따라 무선 환경에서 인터넷을 효과적으로 사용할 수 있는 이동성 관리 프로토콜에 대한 관심이 증가하고 있다. MIPv6(mobile IPv6)는 IPv6 환경에서 이동성을 지원하기 위한 프로토콜로 제안되었고, 이동이 빈번한 셀룰라 환경에서 효율적인 이동성 지원을 위해서 MIPv6의 핸드오버 성능을 개선한 HMIPv6(hierarchical MIPv6)와 FMIPv6(fast handovers for MIPv6) 등의 새로운 프로토콜에 대한 연구가 활발히 이루어지고 있다. 본 논문에서는 HMIPv6의 계층구조를 이용한 효율적 이동성 관리의 장점과 FMIPv6의 선행적 (proactive) 핸드오버 지원에 의한 끊임없는 서비스 지원의 장점을 효과적으로 결합하여 이동이 빈번한 셀룰러 환경에 적합한 새로운 이동성 관리 프로토콜인 HIMIPv6(highly integrated MIPv6)를 제안한다. HIMIPv6는 선행적 이동성 관리를 하위 도메인내의 핸드오버뿐만 아니라 하위 도메인간의 핸드오버에도 적용함으로써 시스템 전체적인 이동성 관리성능을 개선하였다. NS-2 시뮬레이션에 의한 성능 분석은 HIMIPv6가 빈번한 핸드오버 환경에서도 MIPv6, FMIPv6, 그리고 HMIPv6보다 이동성 지원에 필요한 신호 부하를 작게 발생시키고 핸드오버 상황에서의 서비스 끊김 현상이나 패킷 손실률도 작음을 보여준다.

As mass media has come to intervene with politics in a more proactive way during modern times, the image of a politician has evolved into a more relevant factor compared with political content. This phenomenon is known as "image politics", and such externalized images as non-verbal cues have grown in importance, along with the numbers of female politicians. Thus image strategy has been instituted as a major research theme in the field of political marketing, especially for female politicians. In accordance with this theme, this study aims to approach fashion as part of image strategy of female politicians, in order to reemphasize political fashion as a valuable resource. The methodologies employed in this study are based on both the literature and positive research. Female politicians have long utilized fashion styles that are, or are assumed to be, the most appealing to their target base of support in a predominantly male-centered sector. In this sense, appropriate choices in the usage of apparel items, colors, hair styles, accessories, and others according to each situation and respective hierarchies are of the utmost importance. When attending official ceremonies and other related meetings, the strategic superiority afforded to a scientific approach based on thorough fashion research, compared with personal taste is imperative. The significance of this study lies within the recognition of the importance of fashion image, and how to utilize fashion for image strategy in practice, through the investigative synthesis and review of major preceding research.

The purpose of this study is to examine the relation among adolescents' perception of parental overprotection, goal-seeking orientation, self-handicapping and academic procrastination. Questionnaires were administered to 1200 male and female high school students in Gyeonggi Province. A total of 942 questionnaires were statistically analyzed through mean, standard deviation, frequency analysis, one-way analysis of variance, Pearson's correlation analysis, and multiple regression analysis. The major results of the study are as follows: First, adolescents' academic procrastination differed by school grades. Second, for the high-performing group, self-handicapping, goal-seeking orientation and parental overprotection were significant predictors of their academic procrastination. For the mid-level performing group, self-handicapping and goal-seeking orientation were significant predictors of their academic procrastination. For the low-performing group, self-handicapping was the only predictor of their academic procrastination. Third, for the high-performing group, self-handicapping meditated the relation between parental overprotection and academic procrastination. Those results provide useful information regarding proactive support or intervention for adolescents' academic procrastination.

We researched the modern meanings of traditional dining table courtesy education and its correlation with the main values of contemporary personality education based on dining table courtesy education stated in the social norms texts of the Joseon dynasty. Among the social norms of the Joseon dynasty, we chose Sohak, Naehun, Dongmongsuji, Seonghakjibyo, Gyeongmongyogyeol, Jeungbosallimgyeongje, Sasojeol, and Koamgahoon for research. As a result of our research on these documents and books, the modern meanings of the courtesy education at the dining table can be summarized as follow. First, the courtesy education has table manners appropriate for the development level of early children. Second, it teaches right-handed dining manners that match the features of Korean food culture. Third, it has the self-discipline and the values of community life, sharing, solicitude, and communication. Fourth, parents and grandparents are involved in the education. Fifth, it has the core values of modern personality education: manners, filial piety, respect, solicitude, communication, cooperation, and responsibility. Future courtesy education at the dining table should include practical education programs that can consolidate the bond of sympathy between the home, school, and society, and can improve its practice; in addition, to expand the opportunities for education, proactive social support is demanded.

The purpose of this study is to investigate the development and determinants of China-ASEAN trade relations over the period of 2000-2018. Employing both the qualitative and quantitative approaches, the results show that the trade relations between China and the Association of South East Asian Nations (ASEAN) have remarkably developed and rapidly grown over times, with a significantly important concentration on the segments of high technological and medium technological products. We also find that China's economic scale is crucially impacting on the China-ASEAN trade relations under both the aggregate and sub-sector level. It is interesting to notice that there is no evidence to support accession to the World Trade Organization (WTO) and officially forming of ASEAN-China Free Trade Agreement (ACFTA) to enhance trade relation between both sides. The findings also quantitatively indicate that there is much significant potential for the expansion of mutual trade between China and some members of ASEAN such as Brunei, Laos and Malaysia, while less potential is predicted for other members of ASEAN. It is strongly suggested that China and ASEAN should find a new proactive approach and make more efforts in improving the mutual political trusts to enhance trading activities in the coming years.

Cooperative diversity protocols have attracted a great deal of attention since they are thought to be capable of providing diversity multiplexing tradeoff among single antenna wireless devices. In the high signal-to-noise ratio (SNR) region, cooperation is rarely required; hence, the spectral efficiency of the cooperative protocol can be improved by applying a proper cooperation selection technique. In this paper, we present a simple "cooperation selection" technique based on instantaneous channel measurement to improve the spectral efficiency of cooperative protocols. We show that the same instantaneous channel measurement can also be used for relay selection. In this paper two protocols are proposed-proactive and reactive; the selection of one of these protocols depends on whether the decision of cooperation selection is made before or after the transmission of the source. These protocols can successfully select cooperation along with the best relay from a set of available M relays. If the instantaneous source-to-destination channel is strong enough to support the system requirements, then the source simply transmits to the destination as a noncooperative direct transmission; otherwise, a cooperative transmission with the help of the selected best relay is chosen by the system. Analysis and simulation results show that these protocols can achieve higher order diversity with improved spectral efficiency, i.e., a higher diversity-multiplexing tradeoff in a slow-fading environment.
