Recently, mobile communication systems are suffering from exponentially increasing data traffic. As a promising solution to the increase in data traffic, a coordinated multi-point transmission and reception (CoMP) scheme has been proposed. Although a great deal of research has been done on this new technology, the performance of mobile communication systems with CoMP has not been evaluated properly in a typical indoor environment. To address this, we have developed a system-level simulator and evaluated the performance of mobile communication systems with CoMP. Unlike previous works, we have used an actual antenna pattern in our simulator and link-level results are properly taken into account through link-level abstraction. By using a system-level simulator, we have evaluated the performance of mobile communication systems with CoMP in an indoor environment and found that unlike an outdoor cellular environment, CoMP may not improve the performance of overall mobile communication systems in an indoor environment.

클러스터를 위한 기존의 커널 수준 통신 시스템들은 플랫폼에 종속적이고, 사용이 어렵거나 클러스터를 위한 다양한 기능을 제공하고 있지 못하다. 본 논문에서는 리눅스 클러스터 상에서 커널 수준의 어플리케이션 개발을 위한 통신 모듈인 KCCM(Kernel level Cluster Communication Module)을 설계하고 개발하였다. KCCM은 송수신(send/receive) 기반의 동기 통신과 원격 함수 호출(remote procedure call) 기반의 비동기 통신을 모두 지원하며 포팅 가능성을 고려하여 커널 소켓을 이용하여 구현되었다. 또한 TCP와 같은 연결 기반(connection oriented)의 시스템에서 발생할 수 있는 연결 상태의 장애를 복구 할 수 있는 기능을 갖춘 동시에 사용하기 쉬운 인터페이스를 가지도록 설계되었다. 본 논문에서는 실험을 통하여 KCCM의 성능을 RPC(Remote Procedure Call)와 비교해 보았으며 특히 비동기 통신을 요구하는 통신 구조에서 적합함을 보였다.

This study was carried out to learn about the contents of communication between mother and her adolescents in this country, and possible differences in the contents of communication with demographic variables. In particular, I wanted to find out the following; 1)contents of communication between mother and her adolescents. 2)Contents of communication between parents with adolescents. 3)Possible differences in the contents of communication with differences in the level of education, employment status, and age of mother, family income level, and sex, and birth order of children. To test these hypotheses, I distributed questionnaires to 600 mothers of selected high school juniors(11th grade) in Seoul. Four hundred and fourty-eight questionnaires were returned, and the results were analyzed using frequency distribution, percentage, and x2-test. The results were as following; 1) In general, mothers communicated well with their adolescents, especially in topics related to studying, friends, school, parents and family, and future career. Communication on sex-education or sex-role, however, was rather limited in contents. ool, parents and family. Communication on sex-education or sex-role of adolescent was almost never attempted. This result showed similarity with 1 above. 3) (1) contents of communication and educational level of mother; contents of communication between mother and her adolescents differed significantly with educational level on all topics except parents and family, indicating that the educational level of mother, the more diverse was contents of communication between mother and her adolescents. (2) Contents of communication and employment status of mother: On all topics except sex-education, communication between mother and her adolescents differed significantly between employed and unemployed mothers, indicating that unemployed mothers communicate on greater number of topics with their adolescents than employed mothers do. (3) contents of communication and family income level; Family income level did not affect contents of communication between mother and her adolescents significantly. (4) contents of communication and age of mother; Age of mother did not affect a contents of communication between mother and her adolescents significantly. (5) contents of communication and sex of adolescent; Thee were significant differences in contents of communication on certain topics; On virginity, sex, marriage, and dating, mother communicate more diversely with daughters than with sons. This result certainly reflects the deep-rooted traditional value system among koreans, with permissive attitude toward males, and far more strict attitude toward females, on sex-related matters. (6) Contents of communication and birth order of adolescents; The birth order of adolescents did not affect contents of communication between mother and her adolescents significantly.
