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 investigated how the travel motivation of Korean overseas tourists influenced shopping behavior. We first identified factors of the travel motivation and then categorized types and attributes of shopping products and shopping stores. We then examined the relationship between the travel motivation and shopping products and shopping channels. A questionnaire method was applied for this survey, while factor analysis and regression analysis were used to analyze data. The results are listed below. First, nature & leisure, rest, family, pleasure, hobby & fitness, and discovery were identified as 6 factors of travel motivation. Second, shopping products of overseas tourists were categorized into three types: fashion & luxury, daily goods, and memento. There were four attributes of products, namely, design, utility, economy, and prestige. Major types of shopping stores were souvenir shops, fashion channels and local markets; the shopping store attributes identified were location & salesperson, assortment & atmosphere, and display. Third, overseas tourists' motivation was shown to influence the selection of product types and attributes. Those who traveled for rest, family, pleasure, hobby & fitness orientation were inclined to purchase fashion & luxury goods, and daily goods; however, those who traveled for rest and hobby & fitness orientation also tended to buy memento. The effect of the travel motivation was shown to be different according to product attributes. Fourth, tourists' motivation was shown to affect store type selection and attributes. Those whose traveled for rest, family, pleasure, hobby & fitness preferred souvenir shops while those seeking nature & leisure and pleasure tended to visit fashion channels and local markets more often. Travelers seeking nature & leisure and discovery cared for all three store attributes while family oriented and pleasure seeking tourists considered shopping store location, salesperson and display attributes as important.

The author studied the changes of muscle activity with Bioelectric processor Model EM2(Myotronics Corp., USA) before and after occlusal stabilization splint therapy. For this study, 15 temporomandibular disorders patients and 15 students without any temporomandibular disorders symptoms were selected, for experimental group and control group, respectively. Experimental group were treated with occlusal stabilization splint and checked about electromyographic activity before and after therapy. Electromyographic levels were measured in both groups at the following mandibular position, i.e., physiologic rest, tapping, light biting, hard open without pain, open with pain, right excursion and ipsilateral biting, left excursion and ipsilateral biting, protrusion, protrusive biting, edge biting and physiologic rest after movement. The obtained results were as follows : 1. In experimental group, post-treatment mean values of muscle activity were lower than pretreatment values. 2. In general, the pre-treatment mean values of muscle activity in experimental group were higher than those of control group. 3. In experimental group, no statistically significant difference appeared between affected and unaffected side. 4. The mean value of muscle activity in physiologic rest position after each movement check was lower than that before each movement check.

This study was undertaken to compare the activity of masticatory muscle between normal occlusion and anterior openbite. 33 subjects without the experience of orthodontic treatment, missing teeth and the symptom of T. M. disorders were selected for this study : 25 subjects were normal occlusion and 8 subjects were anterior openbite. The ten items were measured from the cephalometric headplates, and EMG recordings of the anterior temporal and masseter muscle were taken at rest position and during maximum clenching at centric occlusion. All data were analyzed and processed with the computer statistical method. The following results were obtained : 1. At rest position, the muscle activities of both temporal and masseter muscle were higher in anterior openbite than in normal occlusion. 2. During maximum clenching, the muscle activities of both temporal and masseter muscle were prominently lower in anterior openbite than in normal occlusion. 3. At rest position, the temporal muscle of anterior openbite showed the highest muscle activity, but showed the lowest muscle activity during maximum clenching. 4. Anterior openbite showed closer interrelationship between facial morphology and the muscle activity, and the muscle activity was more influenced by the form of mandible than that of maxilla.

The purpose of this study was to examine the differences of family leisure motivation and family leisure constraints between German families and Korean families, and analyze the relationship among family leisure motivation, family leisure constraints, and family strengths. The sample in this study consisted of 102 Korean two-parent families with teenagers and 147 German two-parent families with teenagers. The results were as follows: 1) family bonding motivation and rest motivation did not differ significantly between German families and Koran families while educational motivation and obligatory motivation differ significantly between the two. 2) While Korean families were more constrained to intrapersonal constraints, German families were more constrained to interpersonal constraints. 3) Educational motivation, family bonding motivation, rest motivation, interpersonal constraints, and structural constraints were found to be significantly correlated with German family strength while educational motivation, family bonding motivation, rest motivation, and interpersonal constraints were found to be significantly correlated with Korean family strength.

The purpose of this study was to investigate the variables on employees' retirement expectations divided into imposed frustration, new beginning, transition to rest, and continuing. Independent variables were individual(gender, age, occupation, income, education, and health condition), psychological(self-esteem, locus of control, attitude of leisure, and attitude of family), and job-related variables(job attitude, job satisfaction, and job stability). In order to achieve this purpose, a survey was conducted with 515 employees from Daegu and Kyungpook. Retirement expectations were measured with questionnaire based on several studies. The data analyzed by frequency, percentage, mean, factor analysis, Cronbach's $\alpha$, correlation, and multiple regression. The major findings were as follows. First, imposed frustration was affected by income, self-esteem, locus of control, job satisfaction, job attitude, and job stability. Second, new beginning was affected by self-esteem, locus of control, attitude toward leisure and family, and job stability. Individual variables were not statistically significant predictors of new beginning. Third, transition to rest was affected by locus of control, attitude toward family, job satisfaction, job attitude, and job stability. Individual variables were not statistically significant predictors of transition to rest. Finally, continuing was affected by age, education, job satisfaction. Psychological variables were not statistically significant predictors of continuing.

M2M can provide the bi-directional services between applications and objects which have the attached telecommunication module. It consists of the objects, platform, and (web based) applications. M2M can realize In-Transit Visibility and Asset Visibility combined with GIS. Although many applications of M2M, such as metering, monitoring, controlling, tracking et al., are being serviced, the interoperability among the M2Ms is not considered. In this paper, we described the interoperability. Specially, ROA, which is the state of art technology in mash-up, more than SOA, and URN, which is based on Open API in RESTful service, more than URL are studied. As the message protocol between platform and applications, MPM was defined.

A laboratory experiment was carried out to observe and visualize ventilated supercavitation phenomena around a moving underwater body which is attached to a newly designed high-speed (Max. 20 m/s) carriage system in a wave tank. Compared to the existing many other experimental studies using cavitation tunnels, where the body is at rest and the fluid is in motion in a bounded or closed environment, the present experimental study deals with super-cavity formation in unbounded or free-surface bounded environments, where the body is in motion and the fluid is at rest. Main attention is paid to the effective visualization of the steady-state cavity formations around a moving body and, those cavity formations are reported pictorially according to the body speed, ventilated air-pressure, and with or without a cavitator.
