Purpose: The study investigated the relationship among self-esteem, communication and school satisfaction in middle school students. Method: A self-reporting questionnaire was completed by 145 students from October 8-19, 2007. The research tools included established scales of self-esteem, communication, and school satisfaction. The data was analyzed by descriptive statistics, t-test, Pearson's correlation coefficient, one-way ANOVA, and Sch$\acute{e}$ffe's test using the SPSS 12.0 program. Result: Significantly positive correlations were evident between self-esteem and communication, self-esteem and school satisfaction, and communication and school satisfaction. Conclusion: It is necessary to develop a strategy to increase self-esteem, communication and school satisfaction for middle school students.

Inter-vehicle communication is one of the most important parts in Intelligent Vehicle System. Through this communication, drivers can recognize what is happening out of their sights, such as the freezing condition of the street, traffic accidents, and so on. Each car in IVS gives various services to the drivers after analyzing those received information from cars or a base station. If the message is, however, exchanged from car to car directly, the computation cost which is needed for all the car to authenticate the transmitted message between nearby cars is tremendously high. Therefore, one can naturally think that the message communication between cars is performed with the help of the base station to reduce the computation cost. In this case where the base station collects all the information transmitted from cars and broadcasts them nearby, there should be an efficient way both for the base station to authenticate the car message within its communication range and for the car to authenticate the information received from the base station. In this paper, we present a two-way authentication protocol using a hash chain to efficiently exchange GPS information between a car and a base station. This information can be used to provide a driver with the navigation which displays all the moving cars around him in real time. When a car goes into an area of a base station, the car authenticates itself to the base station using its private key of PKI, sends a commitment of a hash chain, then starts to send a message with the hash value for authentication. The message includes GPS information, driver's status and so on. The base station also authenticates itself to the nearby cars using its private key, transmits the commitment of the hash chain, and sends all the messages gathered from cars with authentication information.

치위생학 전공 대학생들의 비판적 사고성향, 의사소통능력, 자율적 교육풍토가 문제해결능력에 영향을 미치는 요인을 파악하고자 한다. 2018년 5월 20일부터 6월 1일까지 2개 대학교에 재학 중인 치위생학과 249명 대상으로 시행하였다. 통계분석은 평균, t-test, one-way ANOVA로 실시하였다. 비판적사고성향의 전체평균은 3.47점이었고 의사소통생활의 전체평균은 3.48점으로 나타났다. 자율적 교육풍토의 전체 평균은 3.14점이었고, 문제해결능력의 전제 평균은 3.40점으로 나타났다. 치위생학 전공 대학생들의 문제해결능력에 영향을 미치는 요인은 비판적 사고성향 점수가 높을수록 문제해결능력이 높게 나타났으며(p<0.001), 전공만족도가 높을수록 문제해결능력이 높게 나타났다(p<0.05). 따라서 치위생학 전공 대학생들의 의사소통능력과 비판적 사고성향, 자율적 교육풍토를 향상하는 프로그램이 적용된다면 문제해결능력을 더 높일 수 있을 것으로 기대한다.

Multicasting is an efficient way of group communications because one sender can transmit data to multiple receivers with only one transmission. Furthermore, multicasting is considered an appropriate transmission method for multimedia services. Multimedia applications are expected to become more prevalent over mobile ad-hoc networks in the near future. Therefore, achieving reliability in multimedia communications is an important task. In this paper, we propose a leader-based reliable multicast medium access control layer protocol for multimedia applications to enhance video quality. We present a Markov chain model and numerical formulation of our proposed system.

The purpose of this study was to analyze self-expression and facilitative communication in university students according the their enneagram personality type. The subjects included 241 university students selected from universities in Seoul and Cheonan. The research tools of this study were the enneagram personality type scale, the assertiveness rating scale(self-expression) and facilitative communication rating scale. The statistics used from this data were one-way ANOVA(Post-hoc Duncan). The results were as follows; first, the self-expression was meaningfully different in content, paralinguistic and nonverbal assertive behavior characteristics by enneagram personality type university students. Second, immediacy, the sub factor of the facilitative communication rating scale varied depending upon the enneagram personality type(enneatype) of university students, Several suggestions were made concerning a study on self-expression and facilitative communication according to the enneagram personality type of university students.

The purpose of this study was to identify the relation between juvenile deliquency and parent-adolescent communication, the family cohesion and adaptability as variables of psychological environment of the family. The subjects were 143 juvenile deliquents in jail, aged 16 to 19, and 347 9th, 10th, 11th, 12th grade students who resided in low income areas in Seoul and Taegu. The research data were collected by structured questionnaire. 143 juvenile delinquents and 87 students whose degree of deliquency was more than M+(0.5*S.D) were selected as the final data source. The statistical methods were frequency percentile, pearson's correlation, one-way ANOVA. Scheffe'test and multiple regression analysis. The major findings showed that (1) juvenile deliquency was significantly related to father-closed communication type. (2) juvenile deliquency was significantly related to low family cohesion and adaptability, (3) the family cohesion and adaptability was positively correlated with parent-adolescent communication. Father-adolescent communication had more important effect upon the family cohesion and adaptability than mother-adolescent communication.

Logic programming has many advantages as a paradigm for parallel programming because it offers ease of programming while retaining high expressive power due to its declarative semantics. In parallel logic programming, one of the important issues is the compile-time parallelism detection. Static data-dependency analysis has been widely used to gather some information needed for the detection of AND-parallelism. However, the static data-dependency analysis cannot fully detect AND-parallelism because it does not provide some necessary functions such as the propagation of groundness. As an alternative approach, abstract interpretation provides a promising way to deal with AND-parallelism detection, while a full-blown abstract interpretation is not efficient in terms of computation since it inherently employs some complex operations not necessary for gathering the information on AND-parallelism. In this paper, we propose an abstract domain which can provide a precise and efficient way to use the abstract interpretation for the detection of AND-parallelism of logic programs.

확장그래프는 통신망의 설계와 분석에 유용하다. Mukhopadhyay 등은 nongroup two predecessor single attractor CA(Cellular Automata; 이하 CA)에 기반을 둔 한 부류의 확장그래프들을 생성하는 방법을 소개했다. 본 논문에서는 group CA인 60/102 Null Boundary CA(NBCA)에 기반을 둔 한 부류의 확장그래프들을 생성하는 방법을 제안한다. 본 논문에서 제안된 방법에 의해 생성된 spectral gap은 Mukhopadhyay 등[12]에 의해 생성된 spectral gap보다 크다. 제안된 확장그래프들의 조합적 성질에 기반을 둔 일방향 함수들을 생성하는 알고리즘을 제안한다. 60/102 NBCA에 의해 생성된 d-정규 그래프를 이용한 일방향함수는 Goldreich의 방법[5]에 기반을 두고 있다.
