  • Purpose: This study was undertaken to obtain the basic data on the spouses‘ stress and adaptation caring their wives affected by gynecological cancer. In addition, moderating variables for adaptation, family resource and situational definition, were also investigated. Method: This study was descriptive survey research work by questionnaire on the 71 spouses hospitalized in an university hospital located on Gwangju from Sep. 2001 to Oct. 2002. Results: The mean score of stress was 2.27, and the mean score of adaptation was 3.12. The correlation between stress and adaptation was significant (r = -.692, p = .000). The adaptation score of high stress group with high family resource was higher (p = .041) than the group with low family resource. The adaptation score of high stress group with high situational definition was higher (p = .033) than the group with low situational definition. Conclusion: This study showed that the spouses experienced a similar level of stress compared with the level of families with other type of cancer. This study also showed that the stress and adaptation levels were different depending upon the family resource and situational definition. This aspect should be considered for the development of nursing intervention program for the spouse of patients with gynecological cancer.

  • Video adaptation in response to dynamic resource conditions and user preferences is required as a key technology to enable universal multimedia access (UMA) through heterogeneous networks by a multitude of devices in a seamless way. Although many adaptation techniques exist, selections of appropriate adaptations among multiple choices are often ad hoc. To provide a systematic solution, we present a general conceptual framework to model video entity, adaptation, resource, utility, and relations among them. It allows for formulation of various adaptation problems as resource-constrained utility maximization. We apply the framework to a practical case of dynamic bit rate adaptation. Furthermore, we present a description tool, which has been accepted as a part of the MPEG-21 Digital Item Adaptation (DIA), along with a brief overview of the .elated descriptors to support terminal and network quality of service (QoS).

  • Based on the theoretical framework of the Double ABCX model of family stress and adaptation, this study was to analysis the causal relationships of stressors (psychological sexual, and physical wife abuse), personal resources (self-efficacy and self-esteem) and social support(emotional and informational support), appraisal(positive appraisal and downward comparisons) with adaptation (psychological well-being and somatic symptoms). Self-administered questionnaire method was used to collect data from 264 wives residing in Chonbuk-do and Kyonggi-do area. The causal model was tested and modified by the maximum likelihood method using UISREL 7 program. Results showed that wife abuse had effect on adaptation indirectly through the latent variables of personal resource and appraisal, which influenced the adaptation directly. In addition, social support indirectly affect the adaptation through personal resource and appraisal. It was also found that all these variables explained 27.6% of the total variance of wives'adaptation, and that personal resources was the most powerful variable in predicting the adaptation of the wives.

  • This study was carried out to leach valuable metal ions from the mine waste ore using the adapted indigenous bacteria. In order to tolerance the heavy metals, the indigenous bacteria were repeatedly subcultured in the adaptation-medium containing $CuSO_4{\cdot}5H_2O$ for 3 weeks and 6 weeks, respectively. As the adaptation experiment processed, the pH was rapidly decrease in the adaptation-medium of 6 weeks more than the 3 weeks. The result of bioleaching with the adapted bacteria for 42 days, the pH value of leaching-medium in the 3 weeks tend to increased, whereas the pH of the 6 weeks decreased. In decreasing the pH value in the adaptation-medium and in the leaching-medium, it was identified that the indigenous bacteria were adapted $Cu^{2+}$ the ion and the mine waste ores. The contents of Cu, Fe and Zn in the leaching solution were usually higher leached in 6 weeks than 3 weeks due to the adaptation. Considering the bioleaching rates of Cu, Fe and Zn from these leaching solutions, the highest increasing the efficiency metal ion were found to be Fe. Accordingly, it is expected that the more valuable element ions can be leached out from the any mine waste, if the adapted bacteria with heavy metals will apply in future bioleaching experiments.

  • The purpose of this study is to examine the influence of family mealtime on the childrens' school adaptation. This study uses data from the 2012 Survey on Child Education and School Involvement of Parents by the Center for Family-School Partnership Policy Research at Seoul National University. Survey data was collected from 1500 parents with school-aged children. For the data analysis, Chi sqaure test and hierarchical linear regression analyses were conducted. The results of these analyses showed that the numbers of family meals shared averaged 4.26 times per week for breakfast and 4.33 times per week for dinner. There were significant differences in the number of family meals shared together according to school level, residence area, and parent employment status, and household income. In addition, childrens' school adaptation was significantly different depending on school level, parent gender, parent education, and parent employment status. Finally, according to the hierarchical regression analyses, the number of family meals shared significantly predicted childrens' school adaptation. The greater number of family meals shared, the stronger the childrens' school adaptation. These results indicate that family mealtime has a positive effect on childrens' school adaptation. This study suggests that family mealtime is an indicator of family strength and it needs to guarantee family shared time at least to have a dinner together. This study could provide grounds for making family policy and education policy in order to guarantee family shared time.

  • The purpose of this study was to determine the protective factors that strengthen the adaptation ability by analyzing individual, family, and social activities variables which impact on the adjustment of retired men. The sample for final data analysis was 233 questionnaires completed by retired men aged from 45 to 65 years living in Seoul and the Metropolitan area. Statistical analyses were carried out using SPSS/WIN which included Frequencies, t-test, one-way ANOVA, and regression analysis. The results were as follows: 1. The degree of the retired men's adaptation was 3.22 out of 5. 2. The retired men's adaptation was affected by the variables in the following order: marital satisfaction, economic life satisfaction, acceptance for retirement, recreational facilities satisfaction, recognition for retirement, and cohesion. These variables explained 65.3% of the retired men's adaptation to life. The findings of this study could be utilized as basic data for developing educational programs and guiding policy-making to help retired men achieve development.

  • In this paper, we introduce an adaptive radio resource allocation for IP-based mobile satellite services. We also present a synchronous multibeam CDMA satellite system using an orthogonal resource sharing mechanism among downlink beams for the adaptive packet transmission. The simulation results, using a Ka-band mobile satellite channel and various packet scheduling schemes, show that the proposed system and resource allocation scheme improves the beam throughput by more than two times over conventional systems. The simulation results also show that, in multibeam satellite systems, a system-level adaptation to a user's channel and interference conditions according to user locations and current packet traffic is more efficient in terms of throughput improvement than a user-level adaptation.

  • 컴퓨팅 기술과 다양한 모바일 디바이스의 발전에 따라 모바일 환경에서의 멀티미디어 콘텐츠에 대한 이용도가 증가하고 있다. 현재 PDA에서 제공되는 멀티미디어 콘텐츠는 비디오, 오디오로 이루어진 콘텐츠로 제한되어 있다. MPEG-4는 비디오, 오디오, 이미지, 텍스트, 2차원 객체 등의 멀티미디어 데이타를 효율적으로 저장, 전송 및 표현하기 위한 국제 표준으로 다양한 사용자 상호 작용과 여러 종류의 객체들로 장면을 구성할 수 있다. 또한 현재 대부분의 MPEG-4 콘텐츠는 대부분 데스크 탑 용으로 저작되었기 때문에 PDA 환경에서 제한된 메모리, GUI 등에서 정상적으로 재생할 수 없다. 따라서 본 논문에서는 객체 기반의 MPEG-4 표준을 이용하여 제한된 리소스를 가진 PDA 환경에서 다수의 객체로 장면을 구성하고 사용자 상호 작용이 가능한 MPEG-4 콘텐츠를 재생하기 위한 PDA 적응 기법에 관하여 기술한다. 제안하는 기법은 크게 3가지로 물리적 적응 기법, 리소스 적응 기법, 이벤트 적응 기법으로 나누어진다. 물리적 적응은 재생기 프리젠터에서 이루어지는 부분으로 콘텐츠 저작 환경과 재생 환경의 물리적 차이에 대한 적응 기법이고, 이벤트 적응은 PDA에서 지원하지 않는 이벤트에 대하여 PDA에 적합하게 변형하는 부분이다. 또한 리소스 적응은 제한적인 리소스를 제공하는 PDA에서 MPEG-4 콘텐츠 재생률을 높이기 위한 기법이다. PDA에서의 MPEG-4 재생기는 제안하는 PDA 적응 기법을 이용하여 객체 기반의 MPEG-4 콘텐츠를 정상적으로 재생할 수 있다.

  • 본 연구는 한국 기업의 글로벌마케팅 프로그램의 표준화-현지화 정도를 결정하는 요인에 관한 실증적 연구이다. 특히 본 연구는 2가지 관점에서 기존 연구와 차별화하고자 하였다. 첫째는 모국-현지국의 환경 차이에 초점을 두는 기존 실증연구와는 달리 글로벌 관점에서 분석하고자 하였다. 두 번째는 본 연구는 상황접근론 관점과 자원기반 관점에서 결정요인을 설정하고 이들 요인의 효과를 검증하고자 하였다. 구체적인 결정요인으로 상황적응론적 관점에서 외부환경 요인인 글로벌 시장의 역동성과 복잡성을, 그리고 자원기반 관점에서 글로벌 마케팅자산을 설정하고 검증하였다. 이를 위해 국제마케팅을 수행하는 국내 기업 128개 업체를 대상으로 설문조사를 실시하였다. 연구 결과, 기업의 글로벌 마케팅자산은 글로벌마케팅 프로그램 표준화 정도와의 정(正)의 관계를 나타는 것으로 나타난 반면에, 글로벌 시장환경 요인은 통계적으로 유의한 관계가 없는 것으로 나타났다. 이는 기업의 글로벌마케팅 프로그램은 상황적응론적 관점보다는 자원기반 관점에서 결정되는 경향이 있음을 사사하는 결과이다.
