The purpose of this study was to evaluate the relationship between marital quality and parent-fetal attachment. The sample included 395 pregnant women and 251 spouses who participated in Pregnant Education Programs. We analyzed the data which were collected by means of a questionnaire from September to November, 2011. The results were summarized as follows: The total marital quality level of pregnant couples was above the average and parent- fetal attachment levels were very high. Result indicated a difference in pregnant women and spouses regarding marital quality and parent-fetal attachment. The pregnant woman's marital quality and parent characteristics (planned pregnant, pregnancy period, birth order) had a significant correlation with parent-fetal attachment. The higher effective communication and conflict resolution regarding marital quality were, the higher parent-fetal attachment was.

This article reviewed the research on factors associated with marital quality and stability. Three major categories of factors were described, including background and context, individual traits and behaviors, and couple interactional processes. This review highlighted findings from cross-sectional and longitudinal studies of the prediction of marital quality and stability. Particular attention was given to marital instruments and procedures that had a solid empirical foundation for understanding the concepts related to measure of marital quality and stability. Also, empirically based intervention programs that had been designed to prevent marital distress and divorce were investigated to figure out the relationship between communication factors and conflict resolution styles. Finally, three theoretical frameworks were drawn from empirical literatures, marital measurment instruments, and programs for marital strength to predict factors associated with the marital quality and stability. Recommendations for future research and implications were described.

This study is an evaluation research which examines the effectiveness of the Marriage Enrichment Program for Middle-Aged Couples(MEPM), This program focuses on the marital dyadic relationship as a family life education The MEPM was developed to strengthen the marital relationships and to improve the potential for individuals and couples. For the effectiveness of the study the author conducted previous survey research with a literature review. The Marriage Enrichment Program was delivered to eight middle-aged couples at Hotel Hilton in Kyung Joo on June 5-6 1995. Through statistical analysis the effectiveness of the MEPM was significant in the areas of couple communication problem solving ability sexual relationship accptance for the value differences and mutual respect. The study also found that changes in thinking is much slower than learning for the new skills and knowledge.

LED나 laser diode와 optical fiber의 coupling efficiency를 높이기 위해서는 lens의 곡율반경을 작게 하는 것이 효과적이다. 본 연구에서는 heating and pulling 반경에 의한 tapered lens를 고안함으로써 최적 size의 lens 제작을 용이하게 하였으며, taper의 특성을 이용하여 고효율 coupling을 가능하게 하였다. 이론적 계산에 의하여 90%까지의 light coupling이 가능함을 보였으며, 실험결과 flat end에 대한 improvement factor는 LED에서 3dB, laser diode에서 6dB까지 증가시킬 수 있었다. epoxy를 사용하여 LED에 pigital을 부착한 결과 온도특성 및 기계적 안정성에서 실용화에 충분할 정도로 우수하였다.

Because a wide variety of multimedia services are provided through personal wireless communication devices, the demand for efficient bandwidth utilization becomes stronger. This demand naturally results in the introduction of the variable bitrate speech coding concept. One exemplary work is the selectable mode vocoder (SMV) that supports speech/music classification. However, because it has severe limitations in its classification performance, a couple of works to improve speech/music classification by introducing support vector machines (SVMs) have been proposed. While these approaches significantly improved classification accuracy, they did not consider correlations commonly found in speech and music frames. In this paper, we propose a novel and orthogonal approach to improve the speech/music classification of SMV codec by adaptively tuning SVMs based on interframe correlations. According to the experimental results, the proposed algorithm yields improved results in classifying speech and music within the SMV framework.

This paper presents face features detection and a new physiological neuro-fuzzy learning method by using two-dimensional variances based on variation of gray level and by learning for a statistical distribution of the detected face features. This paper reports a method to learn by not using partial face image but using global face image. Face detection process of this method is performed by describing differences of variance change between edge region and stationary region by gray-scale variation of global face having featured regions including nose, mouse, and couple of eyes. To process the learning stage, we use the input layer obtained by statistical distribution of the featured regions for performing the new physiological neuro-fuzzy algorithm.

This review examines the rapid growth of qualitative and quantitative of telecommunication industry for past couple of years from customer's viewpoint. Most of the telecommunication products were positioned in the market by the businesses and government's support, but the entity of telecommunication products were never interpreted from the user's viewpoint. Even though, various kinds of telecommunication services have been actively discussed by businesses, government, and IT professionals, it has not been sufficiently discussed by the marketing academia where they need to focus a lot on customer's utility. For the purpose of providing an insight of the telecommunication service marketing strategy, this study looked over old and new directions of growth, failure and evolution of services by focusing on two main pillar of communication business, which is high-speed internet and mobile phone service. Additionally, the research explains and mentions the limit and trend of the telecommunication service marketing, and the future research task that needs to be solved.

본 논문은 한국어와 영어 성별어(genderlect)에 관한 비교연구이다. 성별어란 성(gender)의 차이가 언어에 반영된 현상을 말한다. 일반적으로 여성의 언어가 남성의 언어와 다르며, 이러한 차이가 성차별의 원인이나 증거가 된다는 것에 초점이 맞추어져서 연구가 이루어져 왔다. 본 논문은 성별어 중 여성발화의 특성을 영어와 한국어의 영화와 드라마 대사를 분석하여 알아보고자 하였다. 영어자료에서는 여성어가 주로 어휘 즉, 명사, 형용사, 부사의 사용과 관련하여 나타났으나, 한국어 자료에서는 어휘 뿐 아니라 한국어 경어법의 최고단계인 '합쇼체'와 관련하여 여성이 익숙치 않다는 특성이 드러났다. 일반적으로 공손발화에서는 영어나 한국어 모두 여성발화가 공손표현의 특징과 유사한데, 한국 여성들은 경어법에서 아주높임단계를 선호하지 않는 것으로 나타났다. 한국어와 영어의 성별어의 특징이 공손표현이라는 측면에서는 일반적으로 공유하는 부분이 많지만, 한국 여성들의 경우에는 공손어법 중 경어법의 최고 단계인 '합쇼체'보다는 '해요체'를 선호하는 부분을 주목하였다. 이는 성별어의 세계 보편적인 특성과 개별 문화의 차이가 드러나는 부분이라 하겠다.

This study deals with a counseling case in which a mother requested counseling due to the problems of her daughter, who suffers from multiple tic disorder. The participants of this study included five family members (grandmother, father, mother and two female children) and a total of 23 sessions were held from September 2006 to December 2007. Additional counseling ($24^{th}$ counseling session) was conducted on April 1st, 2009. The data was based on recorded transcripts and notes from 24 family therapy sessions. The study used a constant comparative analysis, which uses matrix and network display as an analysis method suggested by Miles&Huberman(1994). The characteristics of the family of origin and the indifference of the husband had caused the wife stress. The couple had frequent conflicts due to dysfunctional communication methods, a clash of values, sexual dissatisfaction, and a lack of communication. This marital conflict became the primary factor of the daughter's multiple tic disorder. Intervention of the family therapist resulted in the setting of treatment goals based on MRI's communication theory and Bowen's family systems theory in order to solve the problem of the daughter's multiple tic disorder. Also, the therapist's intervention techniques included exploring experiences with the family of origin, shedding light on the multigenerational transmission process, exploring dysfunctional attempts at solutions, the therapist's self-disclosure, providing similar cases, dealing with resistance, and suggesting a new communication method. To solve the problem, the therapist helped the family separate the daughter spatially from her parents. Therefore, the therapist's intervention helped reduce the daughter's tics and improve relationships among the family.
