The purpose of this study was to develop a self-report scale measuring dysfunctional communication behaviors that Korean husbands and wives may use during marital fights. Based on the four concepts of criticism, contempt, defensiveness, and stonewalling proposed by Gottman(1994a), an initial pool of 38 items was developed. Through expert reviews of the 38 items to assess content validity, preliminary 30 items were selected. Using a sample of 89 married couples who were living in Susan, Korea, we conducted item analyses and exploratory factor analyses with the 30 items. These analyses yielded a final 19-item, four-factor scale : criticism(5 items), contempt(5 items), defensiveness(5 items), and stonewalling(4 items). The internal consistency estimates for these subscales were satisfactory. Finally, using another sample of 228 wives, we conducted confirmatory factor analysis to confirm cross validity of the 19-item, four-factor model. The result indicated that this model fitted the data reasonably well. All standardized factor loadings were significant in this model. The results of this study supported reliability and validity of this scale.

The purpose of this study was to explore how family type based on intra system dynamics explained housewives'objective and subjective family financial well-being. The data were collected by means of questionnaire distributed to a stratified sample of 662 housewives in Seoul who usually managers household finances. The questionnaire included family cohesion and adaptability scale, communication scale, financial management scale, and subjective family financial well-being scale. Frequency, percentile, mean, Х$^2$ Pearson’s correlation, one-way ANOVA, multiple regression were used to analyze the data. The study had resulted in five major findings: 1. Among four intra system dynamics elements were highly relationships 2. Families were categorized tv four types, named personal-oriented(N: 164), managerial-oriented(N=169), dynamics(N=154), and non-dynamic(N=134) family. 3. The four types of family were influenced tv age of housewives, duration of marriage, and job status of husbands. 4. The four types of family were significantly related with subjective family financial well-being. The personal-oriented family type was significantly related with objective family financial well-being. 5. The dynamic family type showed the highest effect of subjective family financial well-being. The personal-oriented family type showed the greatest effect of objective family financial well-being. The recommendation for future research and better ways to enhance level of intra system dynamics elements and family financial well-being.

The purpose of this study was to find out the characteristics of foster care of long-distance parents who meet their children on weekend and to examine the relationships among the separation anxiety and maternal guilt in foster care. The subject consisted of 138 employed mothers who are living separately with their children. The instruments used for this study were the Separation Anxiety Scale(Cho & Park,1992), the Maternal Guilt Scale(Kim & Kang, 1997), the Parental Satisfaction Scale(Hyun & Cho,1994), and the Parental Stress Scale(Park,1994). The main results of this study were as followings: 1. Mothers had a tend to rely on family members expecially grandparents for foster care of their children. They usually have visited to meet their children weekend and made a phone call once a day. Parental satisfaction in foster care was reported to be moderately high level. 2. The subject’s separation anxiety was found to be high, and it was strong positive relationships to maternal guilt feeling in foster care. The results of this study have implications for both formal and informal support systems of employed mothers with children. The findings of this study may used as basis for understanding long-distance parents’problems in foster care, developing support programs, and public policy for employed mothers.

This study followed the standardization study pool of K-BSID-II to examine the stability of K-BSID-II. One hundred and ninety five infants aged from 1-42 months tested twice with intervals of 5-16 month between tests. All participants had been full-term babies without any medical complications. There were no significant differences between the groups which were divided in terms of demographic variables such as mothers' education, infants' birth order and gender. The stability of K-BSID-II was significant and that of the mental scale was lower than that of the psycho-motor scale: There were high stabilities between raw scores in two sessions(r=.91 for the mental scale and r=.89 for the psycho-motor scale) but there were significant but low correlations between mental index scores(r=.18, p<.05) and psycho-motor index scores(r=.17, p<.05). The stability was increased with initial test age and mothers' education. It was recommended for testers and researchers to use both raw scores and index scores for better interpretations in future research.

The purpose of this study was to examine the life satisfaction of adolescents in the ecological contexts of their individual, family, school, and social-cultural experiences. The participants were 1,099 middle and high school students in Chungnam-do. Instruments were the Satisfaction with Life Scale, Rosenberg Self-Esteem Scale, Parent-Adolescent Communication Inventory, the School Life Satisfaction Scale, and Social-Cultural Satisfaction Scale. Data analysis involved the use of descriptive statistics, t- and F-tests, Duncan's multiple range test, product-moment correlations, multiple regression, Cronbach's ${\alpha}$, and factor analysis. Results were as follows: Firstly, middle school students showed the highest levels of life satisfaction, and vocational high school students reported the lowest levels. Also, life satisfaction was inversely related to school grades. Secondly, for all the students, life satisfaction was positive correlated with self-esteem, open communication with parents, school life satisfaction, and social-cultural satisfaction. Lastly, open communication with parents and overall satisfaction with life at school explained more of the variance in adolescent life satisfaction than any other factors.

With Internet of Things (IoT) technology, home environment becomes smarter than ever. Not only smart devices such as smart phone or smart TV, but also various IoT devices including sensor, smart thermostat, and smart scale has now become very common on the market. These devices have connectivity to the Internet, so that user can read data from the device or control the device using Internet technology. However, due to diversity of smart home requirements, device collaboration in smart home remains a challenging task still. Usually smart home is built with various technologies to fulfill its own purpose, and these purposes cover very wide area from controlling low-power sensor devices to controlling high-performance devices like smart TV and smart phone. This variety of smart home requirements makes smart home very complicated due to mixed network architecture, protocol and technology. In this paper, a framework to enable managing and collaborating heterogeneous IoT devices in smart home environment is proposed. Several programming models are defined in the proposed framework to make application development for heterogeneous devices more intuitive. The proposed framework has been implemented as a web service, and a case study with real-world smart home IoT devices is presented.

Purpose. With a sample of cognitively impaired nursing home residents and nursing staff, the following were examined 1) the proportion and nature of aggressive behavior, 2) the frequency and types of aggressive behavior, 3) the difference between the residents who demonstrate aggressive behavior and those who do not demonstrate aggressive behavior (age, mental status, functional status, and pain, length of nursing home stay), and 4) nursing staff responses to aggressive behavior by residents. Methods. A cross-sectional descriptive study design was used. Data were collected from cognitively impaired nursing home residents (N=205) and nursing staff (N=60) at two nursing homes using Ryden Aggression Scale I and II, Mini-Mental State Exam, Modified Barthel Index, Verbal Descriptor Scale, and aggressive behavior management questionnaire. Data were analyzed using descriptive statistics including t-test. Results. About $62.9\%$ residents were found to be aggressive and $38.5\%$ were both physically and verbally aggressive. Pushing, making threatening gestures, hitting, slapping, cursing/obscene/vulgar languages, making verbal threats were occurred frequently. Aggressive residents were significantly older, had more cognitive impairment, had more pain, and stayed longer in the nursing home when compared with non-aggressive residents. Considerable proportion of nursing staff responded to aggressive behaviors inadequately. Conclusion. Aggressive behavior among cognitively impaired nursing home residents is prevalent thus needs to be prevented and reduced. Along with environmental modification, educational programs for nursing staff and family caregivers need to be developed and implemented so that they can have extensive knowledge and skills to manage aggressive behaviors.

In this paper, we propose a sound event detection method using a multi-channel multi-scale neural networks for sound sensing home monitoring for the hearing impaired. In the proposed system, two channels with high signal quality are selected from several wireless microphone sensors in home. The three features (time difference of arrival, pitch range, and outputs obtained by applying multi-scale convolutional neural network to log mel spectrogram) extracted from the sensor signals are applied to a classifier based on a bidirectional gated recurrent neural network to further improve the performance of sound event detection. The detected sound event result is converted into text along with the sensor position of the selected channel and provided to the hearing impaired. The experimental results show that the sound event detection method of the proposed system is superior to the existing method and can effectively deliver sound information to the hearing impaired.

Purpose : This study was done to examine the home care service provided by home care nurses and the level of client satisfaction in community. Method : Data were collected from 120 clients who received the home care service at the community home care service center in Pusan from 2th May. 2003 to 31th May 2003. The tool for measurement of satisfaction was composed of 16 items and was 4 score scale by Kim. Data were analyzed by using SPSS/WIN 10.5 program. Result: 1) 67.5% among 120 clients was over sixty years old and 30.6% of clients received home visits 20 times by home care nurse. 2) The total number of home care services was 15,783. And most of the clients received therapeutic nursing care. 3) The mean score of satisfaction on provided home care services was 3.31, among 16 items, "The home care nurses kept up the secret of patients and family" was the highest($3.67{\pm}0.48$). the total level of satisfaction of home care services was very high, with mean score $3.31{\pm}0.32$. Conclusion : The satisfaction level of home care services was very high. so we can expect that the prospect of home care services is very challengeable. Therefore we should try to expand the service recipients with promotional education to assure close ties with the public health centers for the continuous home care service linking and make more efforts to improve the quality of the service.
