This study was conducted to provide the data for the improvement of home health nursing services through the investigation of burden and satisfaction felt by family caregivers under home health nursing care. The study subjects consisted of 200 family caregivers who were enrolled m six university hospital home care services. Data were collected by using constructed questionnaires through mail from March to April of 1999. and analyzed by using t-test. ANOVA, Duncan-test. and Pearson Correlation Coefficients. The results were as follows: 1. The mean score of burden was 2.24. Among the SIX burden dimensions. the highest score was marked in time-dependence dimension. Caregivers were found to have greater burden in the low income families living in flats. In relation to the characteristics of patients. higher scores were shown in the male patients with cerebrospinal diseases. who also revealed higher score of dependency in the Activities of Daily Living. As a whole. there was no significant difference between home nursing care and clinical nursing care in terms of family caregivers' burden. The burden of time-dependence dimension in home nursing care was significantly higher than that of clinical nursing care while the burdens of physical. social. and financial dimensions were significantly lower than those of the clinical nursing care. 2. The mean score of satisfaction was 3.14. Among the six items. the highest score was marked in the nursing care and treatment skill. while the lowest score was marked in the cost containment. Family caregivers with higher academic background and higher income showed higher satisfaction score. The mean score of home care nursmg was significantly higher than that of clinical nursing care.

Purpose. The purpose of the study was to identify the factors, which predict care burden perceived by caregivers of elders with dementia. Methods: The participants in this descriptive survey were 92 caregivers who used one of six daycare centers located in Incheon. The data were collected by questionnaires composed of items on general characteristics of the elders and caregivers, care burden, caregiver fatigue, and functional status of the elders. Results: General characteristics of the elders associated with care burden were age, gender, religion, and the presence of a spouse. Features of caregivers related to care burden were education, relationship with elderly, amount of rest, intention to care, monthly family income, and perceived family economic status. There were significant correlations among care burden, fatigue of caregiver and functional status of the elders. In stepwised multiple regression analysis, significant influencing factors were identified as caregiver fatigue, functional status of the elders, intention to care, relationship with the elders, amount of rest and elder's gender. Those variables explained 46% of variance of care burden. Conclusion: Functional status of elders and amount of rest were significant predictors and are supported by other previous studies. Future interventions for caregivers need to be focused on the slowing down of functional status of elders and increasing of number and length of caregiver's rest periods.

This study was conducted to provide the data for the improvement of cerebral ischemia patient nursing services through the investigation of burden and hospital service satisfaction by family caregivers who were nursing the cerebral ischemia inpatients. The study subjects consisted of 125 family caregivers who were enrolled in four university hospitals with over 300 beds and one Chinese medicine hospital with over 100 beds. The Data were collected from all of the personal subjects using standardized questionnaires by interview from March 1 to March 30 in 2000. Data were analyzed by using t-test, ANOVA. Scheffe's multiple comparison, and Pearson's Correlation Coefficients. The results were as follows: 1. The mean score of burden felt by family caregivers who were nursing the stroke patient was 2.18. In relation to the characteristics of patients, higher scores were shown in male patients who were over 80 years old, and patients who had from 4 to 12 days care giving, over three month duration of admission, from one month to three month duration of illness. The burden felt by family caregivers revealed higher score of dependency in the Activities of Daily Living. 2. The mean score of hospital service satisfaction perceived by family caregivers was 3.35. The highest hospital service satisfaction score was shown in female caregivers, and caregivers whose patients graduated from element school, and treatment method was Chinese medicine, the duration of admission was under 1 month. As a result. the family caregivers' burden was seemed to be high when the patients who were old, male and as care giving time, duration of admission, duration of illness were getting longer. In conclution, hospital service satisfaction was good, but the satisfaction was tend to decrease that family caregivers who were male, higher education background and duration of patients' admission getting longer.

In this work, we present a novel approach to the bit allocation problem that aims to minimize overall distortion subject to a bit rate constraint. The optimal solution can be found by the Lagrangian method with dynamic programming. However, the optimal bit allocation for block-based interframe coding is practically unattainable because of the interframe dependency of macroblocks caused by motion compensation. To reduce the computational burden while maintaining a result close to the optimum, i.e., near optimum, we propose an alternative method. First, we present a partitioned form of the bit allocation problem: a "frame-level problem" and "one-frame macroblock-level problems." We show that the solution to this new form is also the solution to the conventional bit allocation problem. Further, we propose a bit allocation algorithm using a "two-phase optimization technique" with an interframe dependency model and a rate-distortion model.

Breast cancer classification using ultrasound, while widely employed, faces challenges due to its relatively low predictive value arising from significant overlap in characteristics between benign and malignant lesions, as well as operator-dependency. To alleviate these challenges and reduce dependency on radiologist interpretation, the implementation of automatic breast cancer classification in ultrasound image can be helpful. To deal with this problem, we propose a semi-supervised deep learning framework for breast cancer classification. In the proposed method, we could achieve reasonable performance utilizing less than 50% of the training data for supervised learning in comparison to when we utilized a 100% labeled dataset for training. Though it requires more modification, this methodology may be able to alleviate the time-consuming annotation burden on radiologists by reducing the number of annotation, contributing to a more efficient and effective breast cancer detection process in ultrasound images.

Mothers of handicapped children experience many problems and difficulties related to the child's prolonged dependency and demands for special care. Social support can be identified as stress-relieving factor, social support is considered to decrease the amount of negativeness in an individual or family. This study attempted to identify the level of burden and social support in mothers of children who are handicapped, and to determine whether social support is an effective strategy for burden relief in these mothers. The method used in the study was a correlational descriptive survey using a questionnaire. The subjects for the study were 42 mothers who have the handicapped children, between two to twelve years of age, being treated at S General Welfare House for Handicapped and S Rehabilitation Center in Seoul. The data were collected during 1 month from March 20 to April 20, 1996. The instruments used for this study was a structured questionnaire which was the Burden scale developed by Suh Mihae and Oh Kasil(1993) and the PRQ(Personal Resource Questionnaire) scale developed by Brandt & Weinert(1981). The collected data were analyzed using the SPSS computer program, yielding frequencies, percentiles, means, standard deviations, $x^{2}$-test, Pearson's correlation coefficienct, t-test and ANOVA. The results of this study are as follows ; 1)The range of age in the subjects was $29{\sim}44$ years, the range age in the handicapped children was $2{\sim}12$ years. 2) The mean score of burden, for the mothers of the handicapped children was 2.75(standard deviation was 0.47) of a possible total of 5. 3) The mean score of social support, for the mothers of the handicapped children was 4.99 (standard deviation was 0.59) of a possible total of 7. 4) There was an negative correlations hip between burden level and the social support, but there was no statistically significant correlationship between burden level and the social support(r = -.2252, p = .076) 5) In the general characteristics influencing on the burden level was significantly related with the sex(t = - 2.87, p = .007) and the degree of child's handicap level(F = 11.8680, p = .000l). In the general characteristics influencing on the social support was significantly related with the family(husband) support(F = 3.5199, p = .0240). There were significant differences in the mother's levels of burden depending upon the severity of child's handicap. In other words, the degree of mother's burden was directly proportionate to the degree of child's handicap level. There were significant differences in the mother's levels of social support depending upon the family(husband) support. In conclusion, on the basis of the results of this study, there was no statistically significant correlationship between burden level and the social support. Above results suggest that strategies for the intervention programs in diminishing the mother's burden and reinforcing the social support.

Human failure event (HFE) dependency analysis is a part of human reliability analysis (HRA). For efficient HFE dependency analysis, a maximum number of minimal cut sets (MCSs) that have HFE combinations are generated from the fault trees for the probabilistic safety assessment (PSA) of nuclear power plants (NPPs). After collecting potential HFE combinations, dependency levels of subsequent HFEs on the preceding HFEs in each MCS are analyzed and assigned as conditional probabilities. Then, HFE recovery is performed to reflect these conditional probabilities in MCSs by modifying MCSs. Inappropriate HFE dependency analysis and HFE recovery might lead to an inaccurate core damage frequency (CDF). Using the above process, HFE recovery is performed on MCSs that are generated with a non-zero truncation limit, where many MCSs that have HFE combinations are truncated. As a result, the resultant CDF might be underestimated. In this paper, a new method is suggested to incorporate HFE recovery into the MCS generation stage. Compared to the current approach with a separate HFE recovery after MCS generation, this new method can (1) reduce the total time and burden for MCS generation and HFE recovery, (2) prevent the truncation of MCSs that have dependent HFEs, and (3) avoid CDF underestimation. This new method is a simple but very effective means of performing MCS generation and HFE recovery simultaneously and improving CDF accuracy. The effectiveness and strength of the new method are clearly demonstrated and discussed with fault trees and HFE combinations that have joint probabilities.

The purpose of this study was to investigate diversity in the situations of multicultural families regarding the education of their children and to suggest rational ways of educating children in multicultural families. The participants in this study were 16 mothers from multicultural families typically characterized by an international marriage in which a Korean male had married a non-Korean female. The data were collected using intensive interviews over a course of three months and were analyzed by grounded theory. The results of this study showed that the participants had difficulty in adapting to the styles of educating children in Korean families and that they could not help their children do homework by themselves due to the limited personal relationships, the shortage of information about educating children, and an lack of organized education programs on Korean culture and history. Thus, they solved these problems by depending on different extracurricular activities and thus incurred a financial burden to support these activities. This led to excessive amounts of time and energy to earn the money to support the activities, which gave them few opportunities to acquire information on educating children by, for example, meeting with others. This explained their dependency on different extracurricular activities so as to solve the problem of their educating children. In an effort to seek ways to break this vicious circle, this study emphasized that policies related to educating children in multicultural families should focus on helping multicultural families strengthen their abilities to educate their children fundamentally.

Object Generator is a software to provide simulation object data(aircraft, ship, submarine, missile, torpedo) for sumulators in LBTS(Land Based Test System). but there is a burden to the system, because Object generator needs to send many object's data, display objects in a tactical screen, show object's information in a list in 1 second. This paper suggests a parallel software structure taking a few factors(deadlock, dependency) into consideration. At last, the paper shows the performance of the parallel structure's software compared with the former structure's software.

The purpose of this study was to explore the concept of quality of life for bone marrow transplant (BMT) survivors and to gain understanding of nursing interventions that may improve QOL in this population. The data was gathered from 32 BMT survivors using seven open-ended questions. The items were based on previous research of Ferrell et al., (1992). Content analysis was performed on written responses to seven questions regarding BMT and QOL. The results were as follows : 1. The meaning of QOL for BMT survivors were "being healt", "being able to take a role", "having relationships", "self-accomplishment", "peace of mind", "spiritual well-being", "economic stability" and "being alive". 2. The impact of BMT on physical well-being were "skin impairment", "digestive problems", "infections ", "fatigue/weakness", "arthralgia", "eye dryness". "weight gain", "amenorrhea" and "hand tremor". 3. The impact of BMT on psychological well-being were "fear of recurrence", "sence of peace" and "hope". 4. The impact of BMT on socioeconomic status were "financial burden", "limitation of social activities" and "sence of withdrawal". 5. The impact of BMT on spiritual well-being were "dependency on Supreme Being", "spiritual arousal " and "spiritual maturity". The findings of the study will be useful in constructing a instrument to measure QOL in BMT and in understanding the conceptual basis of QOL for the BMT population.ency on Supreme Being", "spiritual arousal " and "spiritual maturity".
