This paper proposes the necessity of a walking period in footstep planning and details situations in which it should be considered. An optimization-based fast footstep planner that takes the walking period into consideration is also presented. This footstep planner comprises three stages. A binary search is first used to determine the walking period. The front stride, side stride, and walking direction are then determined using the modified rapidly-exploring random tree algorithm. Finally, particle swarm optimization (PSO) is performed to ensure feasibility without departing significantly from the results determined in the two stages. The parameters determined in the previous two stages are optimized together through the PSO. Fast footstep planning is essential for coping with dynamic obstacle environments; however, optimization techniques may require a large computation time. The two stages play an important role in limiting the search space in the PSO. This framework enables fast footstep planning without compromising on the benefits of a continuous optimization approach.

In this study, we aimed to look at what dilemmas of science teaching elementary school teachers experience and how they cope with their dilemmas in everyday science classes. Three elementary school teachers participated and qualitative data such as class log, class video, and interview materials were analyzed in inductive ways. The main findings are as follows. First, the dilemmas were classified based on the four factors that make up the science class; teacher, student, learning content, environment. However the dilemmas appeared to be not only one factor involved, but the rest of the factors intertwined. Thus, it was interpreted how the main factors causing the dilemmas conflicted with other factors. Second, the types of teachers' coping strategies to the dilemmas could be largely divided into 'give-up', 'stick to' and 'modified'. In some cases, teachers gave up on what they valued and did not take active action ('give-up'), teachers chose what they valued and made decisions to actively realize it ('stick to'), and in others, conflicts were adjusted by introducing new methods or elements to their classes ('modified'). Based on these results, we discussed that the teacher's dilemmas could facilitate the teacher's learning or professional development.

Purpose: This study was designed to construct a structural model for symptom management of life of the patients with chronic fatigue. The hypothetical model was developed based on the literature review and Self-regulating Model. Method: Data were collected by questionnaires from 252 patients with chronic fatigue in the 8 community from December 2002 to April 2003 in Seoul. Data analysis was done with SAS for descriptive statistics and PC-LISREL Program for Covariance structural analysis. Result: The fit of the hypothetical model to the data was moderate, thus it was modified by excluding 4 path and including free parameters and 3 path to it The modified model with path showed a good fitness to the empirical data($x^2$=318.11, p=0.0, GFI=.98, AGFI=.98, NNFI=.95, RMSR=.03, RMSEA=.05). The symptoms of stress, self-efficacy, and present fatigue level were found to have significant direct effect on symptom management of the patients with chronic fatigue. The ways of coping, perceived stress, and fatigue symptom were found to have indirect effects on symptom management of the patients with chronic fatigue. Conclusion: The derived model is considered appropriate in explaining and predicting symptom management of the patients with chronic fatigue. Therefore, it can effectively be used as a reference model for further studies and suggested direction in nursing practice.

Purpose: This study was to develop a stress-adaptation model for family caregivers of cancer patients that could provide the basis of planning nursing intervention. Method: A hypothetical model was developed using the family adaptation model proposed by Haley et al. (1987). In the literature, the stressor was identified as patient's characteristics, caregiver's characteristics, duration of illness, and family life events. It affected stress appraisal, family resources, family coping and finally caregiver's adaptation. In this model, 18 paths were constructed. Data were collected from 241 caregivers, whose family members were in treatment between June and August 2000, at 3 university hospitals and were analyzed by SPSS and LISREL programs. Results: 1) The overall fitness indices of the hypothetical model were x 2=267.78 (P= .0), GFI= .92, AGFI= .87, NFI= .93, NNFI= .93, PNFI= .64, PGFI= .55, and RMR= .43. Ten of the eighteen paths proved to be significant. 2) To improve the model fitness, the hypothetical model was modified considering modification indices and the paths proved not significant. Final model excluded 3 paths demonstrated to be improved by x2=161.96 (P= .00), GFI= .95, AGFI= .91, NFI= .96, NNFI= .96, and RMR= .23. Twelve of fifteen paths proved to be significant. 3) Stress appraisal was influenced by disease related characteristics and duration of illness and was explained 22% of the variance. Family resources were influenced by stress appraisal and was explained 57% of variance. Family coping was influenced by disease related characteristics, caregiver's characteristics, duration of illness, family life event, and stress appraisal and was explained 57% of variance. Family caregiver adaptation was influenced by disease related characteristics, caregiver's characteristics, stress appraisal, and family coping and was explained 31% of variance. Twelve of fifteen paths were significant. Conclusion: Based on this study, to help family caregivers to adapt, individual intervention is necessary with consideration of disease related and caregiver's characteristics and duration of illness. The intervention should include efforts to raise the family resources and to identify positively the stress they encounter, and there is a need to establish an adaptation model that considers emotional aspects of family caregivers. Since there is a difference in emotional status depending on the disease stage, a study needs to be done to analyze the differences among the disease stages (diagnosis, treatment, recurrence, and terminal stages).

The purpose of this research was to identify nursing interventions performed by MICU and SICU nurses. For data collection this study used the taxonomy of the Nursing Interventions Classification (NIC : 433 nursing interventions) which was modified by McCloskey and Bulecheck(1996). Each of the 433 interventions were identified as used by MICU and SICU nurses. More than 50% of the ICU nurses performed 280 nursing interventions at least monthly. Rarely used interventions included 26 nursing interventions in the childbearing care class. Overall, both MICU and SICU nurses used interventions in the Physiological : Complex domain most often on a daily basis and the interventions in the Family domain least often. The most frequently reported interventions as being used daily in the MICU were chest physiotherapy, airway suctioning and coughing enhancement and, in the SICU, documentation and airway suctioning. There were significant differences between MICU and SICU nurses in 17 nursing interventions childbearing care, cognitive therapy, communication enhancement, coping assistance, elimination management, lifespan care, health system mediation, immobility management, medication management, neurologic management, patient education, psychological comfort promotion, physical comfort promotion, respiratory management, risk management and information management. The SICU nurses performed there interventions more frequently than the MICU nurses. These findings will help in building of a standardized language for the MICU and SICU and enhance the quality of nursing care.

The purpose of this study was to determine the relationship between social support and health behavior in girl high school students in all girl schools. The subjects were 190 girls in 2 Kunsan schools. The instruments used for this study were the social support scale developed by Park(1985) and the health behavior scale developed by Walker etc(1987). As modified by Lee & Han(1996). The data were analysed by correlation coefficient, regression coefficient using an SAS program. The results of this study were as follows: 1. The mean score of social support was 3.96 and the mean score of health behavior was 3.33. 2. 1) General characteristics were related to the degree of social support: personality, spending money, friend number, exercise(p<0.05). 2) General characteristics were related to the degree of health behavior: personality, spending money, friend number, exercise, stress(p<0.05). 3. The hypothesis of this study, 'The higher the degree of social support perceived by the student, the higher the degree of health behavior' was supported(r=0.5730, p=0.0001). For these subjects, there was a significant relationship between social support and the degree of health behavior. Nurses should plan interventions in promotion health behavior with social support as a significant factor in adolescents. If so, their coping ability and well- being may be promoted.
