A new digital media ear started a couple of months ago when 10 major cities in USA first boradcasted the all digital HDTV on the air. Digital video compression has been studied for decades but only recently, it becomes practical and is used in our daily life. We give an overview of the progress of video compression in recent years, particularly, the ones related to international standards. Through examples, we like to introduce this fantastic subject to the readers who were not familiar with it before.

통신위성의 임무 및 위성 체 동역 화 해석 시스템은 서브 시스템별로 몸체를 분류하고 이들 몸체각각의 운동뿐 아니라 위성 체 전체의 운동을 고려하여 정해진 임무에 대하여 위성 체의 자세제어와 궤도조정을 할 수 있도록 다 몸체 동역 학 모델 링 방법을 채택하였다. 따라서 본 시스템은 어느 특정한 통신위성에만 적용되는 것이 아니라 일반적인 통신위성에 적용할 수 있는 통신위성 임무 및 위성 체 동역 학 해석 시스템이다. 시뮬레이션 결과를 2차원 그래픽 및 3차원 동화상으로 파악할 수 있도록 하였으며 또한 사용자 친화방식을 채택하여 누구든지 본 시스템을 쉽게 사용할 수 있도록 하였다. 개발된 시스템의 성능을 검증하기 위하여 현재 운용 중에 있는 정지궤도 통신위성인 무궁화위성 1,2호의 시나리오에 대하여 시뮬레이션을 수행하였다.

The major purpose of this study was to investigate the causal effect of the primary triad experiences on dating relationship satisfaction through self-esteem among college students. The primary triad experiences were composed of the parents' differentiation level of couple relationship and the parent-child relationship including family rule, triangulation and communication. Dating relationship satisfaction included such subscales as problem-solving communication, global satisfaction, affection communication and time together. The study data were collected from 382 college students by using self-administered questionnaire method. The results showed that parents' differentiation was positively correlated with self-esteem and all components of dating relationship satisfaction and that family rule was negatively associated only with problem-solving communication. Triangulation was negatively related with most components of dating relationship satisfaction and self-esteem, while parent-child communication showed positive correlations with the same variables. Path analysis results showed that self-esteem mediated the effect of most variables of primary triad experiences on dating relationship satisfaction. In addition, variables of the primary triad experience had direct influences on most components of dating relationship satisfaction. Self-esteem was found to be the most powerful variable influencing dating relationship satisfaction. The findings of the study were discussed in terms of pre-marital education and counseling.

The purpose of this study was to develop and test the structural model of a contraceptive behavior in Married Korean women. A hypothesis model was constructed on the basis of the health belief model, the theory of planned behavior and extensive literature review of contraception. The model was built by seven constructs. Four exogeneous variables included in the model were consisted of the contraceptive knowledges, the perceived threats, the sexual autonomy and the communication within a couple. Four endogenous variables were consisted of the attitudes toward contraception, the perceived control, the ability to plan a intercourse and the contraceptive behaviors. Empirical data for testing the hypothetical model were collected by the self report questionnaires from 243 Korean married women. The questionnaires used in this study were developed by this researcher and their Cronbach's alpha scores were ranged from .60 to .88. The collected data were analyzed by SPSS program(ver. 8.0) for descriptive statistical analysis and LISREL program(ver. 8.12a) for covariance structural analysis. On the basis of this results, it could be suggested that contraceptive behaviors be greatly affected by the perceived threats, the communications within couple, the attitudes toward contraception and the perceived control. Finally this model would be useful for the practice, theory and research of nursing.

The purpose of this study is to analyze the characteristics and changes of elderly households in rural area. The elderly were classified as elderly living alone, elderly couple living together, and elderly living with their children. Data from the survey of Ministry of Health and Welfare conducted in 1998, 2008, 2017 were used for the analysis. The subjects of the study included a sample of 9,401 respondents who represent aged 65 or more in Korea. The result of analysis was as follows; First, over the past 20 years, there has been no significant difference in the composition of the sexes of elderly in rural area, and aging is becoming more serious. Second, elderly living with children continue to decrease, and elderly couple are increasing. The number of elderly living alone is on the increase, but it tends to decrease in 2017. Third, the proportion of houses in elderly households is still very high, but it is gradually decreasing and the proportion of apartments is increasing. Fourth, the frequency of communication with children tended to increase slightly in all household types, while the frequency of encounter decreased slightly in 2008 and then increased in 2017. Fifth, the health status and economic status of the elderly have been gradually improved over the past 20 years. Finally, the emotional support in all elderly households is maintained constantly, but the instrumental support is gradually weakened.

본 연구는 결혼이주여성의 결혼적응에 영향을 미치는 요인을 파악하고자 하였다. 분석에 활용한 자료는 부산대학교 사회과학연구소가 조사한 "결혼이주여성의 자아탄력성과 결혼적응"이다. 분석은 각 독립변수와 결혼적응의 관계를 다변량분석과 중다회귀분석을 통해 살펴보았다. 연구결과에 의하면, 결혼만족은 배우자지지, 가족생활스트레스, 의사소통수준이 영향을 미치는 것으로 나타났다. 이혼 의도는 자녀수, 가족생활스트레스가 영향을 미치는 것으로 나타났다. 부부간 애정은 결혼기간, 배우자 지지, 의사소통수준이 영향을 미치는 것으로 나타났다. 결혼이주여성의 결혼적응에서 가족생활스트레스가 공통적이며, 가장 영향력이 큰 변수로 나타났다. 결혼이주여성들의 가족생활스트레스를 줄이기 위한 체계적이고 구조적인 지원이 필요하다는 것을 제안하였다.

The purpose of this study was to analyze phenomena and characteristics of family nursing in Korea based on the study by Yun et al. (1999) by ICNP. The subjects of this study were 115 reports on family nursing care in Korea National Open University. The results of this study were as follows; 1. In the phenomenon of family nursing, 'Inappropriate family coping' comprised of 17.0% and 'Inadequate care for a sick member' comprised of 16.8%. 2. It was found that 'A few close neighbors was 62.5%, 'Lack of communication between married couple' was 60.0%, 'Neglet of general child rearing' was 40.9%, 'Closed communication pattern of the head of a family' was 36.0%, and 'Inadequate distribution of each family member's role' was 27.2%. 3. 'Lack of family interaction in community' and 'Social isolation' were combined with 'Lack of family interaction in community', and 'Disturbance in family communication' and 'Lack of family intimacy' were combined with 'Disturbance in family communication'. 4. 'Dual-loading with office work and housework', 'Overload of caring one's elders because of the status as a dual-income family' and 'Lack of family support system' were added into 'Inappropriate family coping'.

이동 물체의 이동 거리 추적이나 대상 물체의 인식과 판별 물체의 특징 추출과 같은 응용분야에서 컴퓨터(Computer)와 비젼시스템(vision system)을 이용한 영상 데이터 처리 분야에 대한 이용률이 증가하면서, 그에 따른 연구가 활발히 진행되고 있다. 따라서 CCD 카메라(Charge-Couple Device Camera)로부터 입력된 그레이 레벨(Gray Level)의 영상을 입력받아 처리과정을 거쳐 위치정보를 전송하는 과정에서 정확한 정보를 얻기 위한 전처리 과정 방법을 제안하고, 실제 시스템에 적용한 결과를 제시한다. 여기서 영상의 전처리 과정 중 입력 영상에서 불필요한 부분을 제거하거나, 배경과 대상물의 분리, 내포된 잡음을 없애기 위하여 흔히 이진화 방법을 많이 사용한다 특히 이진화 과정에서 그레이 레벨의 입력영상에서 히스토그램(histogram) 정보를 이용하여 영상의 이진화시의 임계값을 찾는 것은 아주 중요한 요인이다 따라서 본 논문에서는 신경회로망을 이용하여 실시간으로 CCD 카메라를 통하여 입력되는 그레이 레벨의 입력 영상에 대하여 동적으로 적당한 임계값을 .찾는 방법을 제안하고자한다. 또한 제안한 신경회로망을 이용한 임계값 추출 알고리즘(algorithms)을 구현한 시스템(system)에 적용하여 일반적인 방법과 비교 검토하고 응용 가능성을 확인한다.

ICT(information and communication technology) has played a pivotal role in the world economy, and the out look for ICT has improved markedly. One of the noticeable characteristics in the ICT sector Is the global rationalization of its technology and service. Specialization on the specific ICT capability is a pressing problem for many countries. Along the line of classical innovation cluster and network studies, this paper suggests a way to find and analyze the role of core technologies on the ICT network First, technology network is constructed by using patent citation data from USPTO. Then, a couple of cluster is generated by K-means clustering technique. Finally, brokerage analysis is applied to manifest the role of principal technologies. The network visualization and some stylized facts on dynamics are briefly given altogether Based on the role and relationship of technologies across clusters, it is expected that this research could contribute to the ICT cluster formation and the vision-making for ICT specialization at the viewpoint of technology Policy.
