Demand/withdraw communication is an important dysfunctional pattern of serial arguing. This study aims at addressing factors that affect the ways in which self-demand/partner-withdraw pattern increases the likelihood of persistence of serial arguing. We posit that sensitivity to rejection is positively related to the degree to which individuals perceive a partners' behavior as generally disconfirming, which is positively related to enactment of self-demand/partner-withdraw during an argumentative episode. This sequence is positively related to perception of arguments as unresolved. In addition, among those who reported their argument was resolved, this sequence is positively related to the likelihood that the argument is resolved without mutual agreement. Serial mediation analysis confirmed that the likelihood of resolution without mutual agreement were positively associated with rejection sensitivity partially because high RS individuals are likely to perceive their partner to be generally disconfirming and to enact self-demand/partner-withdraw communication during the episode. However, this pattern did not apply to perception of the argument as resolved.

Physician's Duty of Information is classified into three categories by legal function: 'Duty of Information to Report' to fulfill the patient's right to know; 'Duty of Information to Guide' patient's convalescing and staying healthy; 'Duty of Information to Contribute' to patient's self-determination. We classify the physician's duty of information because the legal effect from the breach of duty varies accordingly. The legal effect is focused on damage compensation responsibility for breach of duty. When a physician violates 'Duty of Information to Report', he subjects himself to liability of compensation for infringing on the patient's 'Right to Know'. When a physician violates 'Duty of Information to Guide', she subjects herself to liability for general medical malpractice. Finally, when a physician violates 'Duty of Information to Contribute', the physician is basically liable for violation of the patient's 'Right to Self- Determination' which refers to infringement on freedom of choice. However, in the case of situation that patient's refusal to the medical treatment would be presumed, the physician bears all liability for the patient's damage which includes both of property and mental damage.

자동음성인식 시스템을 이용하는 사용자 입장에서 보면 음성인식시스템을 사용하기 위하여 음성을 입력할 때마다 버튼을 눌러야 하는 Push-To-Talk (PTT) 방식은 여간 번거로운 일이 아닐 수 없다. 그리고 사용자가 원거리에서 음성을 입력하는 경우처럼 PTT 방식 자체가 용이하지 못 한 음성인식 응용분야에서는 Non-Push-To-Talk (NON-PTT) 방식의 필요성이 대두되게 된다. NON-PTT 방식의 음성 전처리를 위해서는 입력신호로부터 음성신호만을 구분해내는 음성판별기술이 필수적이다. 하지만 일상적인 잡음환경에서 음성신호만을 구분해내는 일은 매우 어려운 일이 아닐 수 없다. 본 논문에서는 일상적인 가정잡음환경에 강인한 음성판별방식을 제안한다. 여기서는 음성판별을 위해서 음성의 유성음 특성을 이용하였다. 즉, 일정구간 이상의 음성신호에는 일정구간이상의 유성음 구간이 존재하며 만약 잡음환경에서도 유성음 구간을 잘 검출할 수 있다면 이러한 음성의 특성을 이용하여 검출된 신호가 음성인지 아닌지를 판별할 수 있다. 이를 위하여 여기서는 가정잡음환경에서도 유성음을 잘 검출할 수 있도록 11 가지 유성음 특징들과 이를 이용한 음성판별방법을 제안하였다. 제안된 방법의 성능 평가를 위하여 음성의 끝점검출방법과 통합하여 음성/비음성 판별 테스트를 수행하였으며 테스트 수행결과 열악한 잡음환경에서 80%이상의 비음성을 거절하는 성능을 보였다.

Purpose : This study examined characteristics of, problems of and services provided to hospice recipients and their family members at a home hospice organization. Methods : The subjects were 113 people who were discharged from one free-standing home hospice organization between November, 1994 and lune, 1999. Since the opening of the organization in November of 1994, it has provided hospice services at patients' homes with no charge. Data were collected from those subjects' records. Results : The average age of the subjects was 57.1 years; those aged 60 and over were 54%. Spouse was the most frequent(50.9%) primary caregiver followed by daughter-in-law and daughter. All the subjects were diagnosed as having cancer. Of those 41 subjects who did not know their terminal stage in the beginning, 31 subjects came to know their states. Of the subjects, 72.7% were referred from their physicians. On the average, the service duration and the number of home visits were 6.8 weeks and 7.2 times, respectively. Pain was the most prevalent problem of the subjects(89.4%). Medication management was the most frequently provided service followed by psychological supports. The reasons for discharge were death(88.5%) and refusal(8%). Home was the most frequent place of death(60%). Conclusion Home hospice service providers should be trained particularly in working with elders and in managing cancer pain. People need to be referred at an appropriate time for achieving goals of hospice. Community recognition of hospice services needs to be promoted.

In this paper, a new unsupervised image segmentation algorithm is proposed. To model the contextual information presented in images, the characteristics of the Markov random fields (MRF) are utilized. Textured images are modeled as realizations of the stationary Gaussian MRF on a two-dimensional square lattice using the conditional autoregressive (CAR) equations with a second-order noncausal neighborhood. To detect boundaries, hypothesis tests over two masked areas are performed. Under the hypothesis, masked areas are assumed to belong to the same class of textures and CAR equation parameters are estimated in a minimum-mean-square-error (MMSE) sense. If the hypothesis is rejected, a measure of dissimilarity between two areas is accumulated on the rejected area. This approach produces potential edge maps. Using these maps, boundary detection can be performed, which resulting no micro edges. The performance of the proposed algorithm is evaluated by some experiments using real images as weB as synthetic ones. The experiments demonstrate that the proposed algorithm can produce satisfactorY segmentation without any a priori information.

When it is not easy to decide the credit scoring for some loan applicants, credit evaluation is postponded and reserve to ask a specialist for further evaluation of undecided applicants. This undecided inference is one of problems that happen to most statistical models including the biostatistics and sportal statistics as well as credit evaluation area. In this work, the undecided inference is regarded as a missing data mechanism under the assumption of MNAR, and use the bivariate probit model which is one of sample selection models. Two undecided inference methods are proposed: one is to make use of characteristic variables to represent the state for decided applicants, and the other is that more accurate and additional informations are collected and apply these new variables. With an illustrated example, misclassification error rates for undecided and overall applicants are obtainded and compared according to various characteristic variables, undecided intervals, and thresholds. It is found that misclassification error rates could be reduced when the undecided interval is increased and more accurate information is put to model, since more accurate situation of decided applications are reflected in the bivariate probit model.

For 2007 Korea presidential election, most polls by telephone surveys indicated Lee Myung-Bak led the second runner-up Jung Dong-Young by certain margin. The margin between two candidates can be estimated accurately by averaging individual poll results, provided there exists no systematic bias in telephone surveys. Most Korean telephone surveys via telephone directory are based on quota samples, with the region, the gender and the age-band as quota variables. Thus the surveys may result in certain systematic bias due to unbalanced factors inherent in quota sampling. The aim of this study is to answer the following questions by the analytic methods adopted in Huh et al. (2004): Question 1. Wasn't there systematic bias in estimates of support rates. Question 2. If yes, what was the source of the bias? To answer the questions, we collected eighteen surveys administered during the election campaign period and applied the iterated proportional weighting (the rim weighting) to the last eleven surveys to obtain the balance in five factors - region, gender, age, occupation and education level. We found that the support rate of Lee Myung-Bak was over-estimated consistently by 1.4%P and that of Jung Dong-Young was underestimated by 0.6%P, resulting in the over-estimation of the margin by 2.0%P. By investigating the Lee Myung-Bak bias with logistic regression models, we conclude that it originated from the under-representation of less educated class and/or the over-representation of house wives in telephone samples.

This study investigated the eating habits of elementary school children and their perceptions related to traditional Korean foods, based on the health belief model. The subjects were fifth grade elementary school children (274 boys and 274 girls) in eight Korean cities. The results were as follows: The children ate almost three meals per day and were grateful for their meals. However, they irregularly consumed meals and snacks. They tended to eat heartily and did not eat foods that they had not yet eaten. Their meals were based on rice and they have eaten kimchi and vegetables at almost every meal. However, they had undesirable habits in eating other foods, such as fruits, fish, soybeans, and sweet foods. They did not sensitively or seriously perceive their eating habits in relation to their health. They perceived that it was very good for their nutrition, health, and tastes to eat traditional Korean foods, and they had pride in traditional Korean foods and eating style. Although they expressed some difficulty regarding availability and preparation of traditional Korean foods, they hardly felt difficulty in eating them. They had high dietary self-efficacy with regard to eating these foods, except for two items of self-regulation. Their eating habits showed positive correlation with dietary self-efficacy, perceived susceptibility, and perceived benefit. In conclusion, eating habits of elementary school children in relation to traditional Korean foods are not desirable, but not serious. They did not sensitively or seriously perceive their eating habits in relation to their health. However, they perceived that it was very good for their nutrition and health to eat traditional Korean foods, did not have a high level of difficulty in eating them, and had high dietary self-efficacy with regard to eating them. Therefore, we suggest that children should be exposed to various traditional Korean foods, along with education about them, in order to enhance their concern and motivation to eat them.
