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.

Microlenses with an extremely small radius of curvature are efficiently use d to couple LED/laser diode light into optica1 fiber. We propose a Tapered lens for the highly efficient coupling of the optical fiber communication light souses into the fiber. Ray optical analysis shows that the maximum coupling efficiency is as high as 90 %, Tapered lens with optimum parameters are fabricated by using heating and pulling technique. Experiment shows that this new technique improves the coupling efficiency by two and four times for LED and laser diode, respectively, as compared with the simple flat - end coupling.

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.

It is generally accepted that there are differences between men and women in linguistic communication style. Genderlect is a socio-linguistic term to refer to the linguistic differences spoken by specific gender. Some linguistic features are provided as evidence to show the genderlects: pitch, lexicon, intonation, grammar and styles. The purpose of this paper is to compare the characteristics of genderlect in English and Korean. To do so, I analyzed the scripts of an English movie, 'Mrs. Doubtfire' and Korean tv drama, 'Oohlala couple'. In "Mrs. Doubtfire, tension and laughter arose out of discrepancy from the way he looked (as a woman) and the way he spoke (like a man). The same is true with "Oohlala couple." In the language of Mrs. Doubtfire, male speech characteristics with nouns were salient while in "Oohlala couple" with verb forms, especially with honorific style, which shows a difference between Korean and English genderlect. Korean language has special genderlect characteristics with honorific speech style realized in verb endings. In Korean the highest honorific speech style, 'Habsho-che' is used in official situation and men are more accustomed to it than women. When women have to use polite expressions they have to choose between the highest honorific style, 'Habsho-che' losing the female characteristics or the second highest honorific style 'Haeyo-che' keeping the female characteristics.

In this paper, X-band satellite communication oscillator of double phase locked is implemented by constructing a couple of phased-locked loop, and then we have analyzed the phase noise of designed PLL-DRO. The designed phase-locked oscillator is consist of series feedback DRO, frequency divider, phase detector, loop filter and programmable PLL-IC. By dividing oscillation frequency of 12.6 GHz into two frequencies, it exhibits output power of 15.32 dBm at 6.3 GHz. Phase noises of implemented oscillator are -81 dBc/Hz@100Hz, -100.86 dBc/Hz@1 kHz, -111.12 dBc/Hz@10 kHz, -116 dBc/Hz@100 kHz and -140.49 dBc/Hz@1 MHz respectively. These indicate excellent stable operation of oscillator and very good phase noise characteristics.

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.
