Purpose: This study aimed to investigate the effect of active vibration exercise on trunk muscle activity, balance, and activities of daily living in patients with chronic stroke. Methods: Twenty-four patients with chronic stroke were randomly assigned to an experimental (n=12) or a control (n=12) group. The experimental group performed an active vibration exercise workout for 20 minutes a day five times a week for 4 weeks using a flexi-bar. Trunk muscle activity was measured using surface electromyography. Balance was measured using the Berg balance scale. Activities of daily living were measured using the functional independence measure. Results: The intragroup comparison showed significant differences in the rectus abdominis, internal oblique, and external oblique muscle activity values, Berg balance scale score, and functional independence measurement values in the experimental group. The intergroup comparison showed that differences in the rectus abdominis and internal oblique external oblique muscle values, Berg balance scale score, and functional independence measurement value for the experimental group were significantly related to those in the control group. Conclusion: Based on these results, this study proved that the active vibration exercise effectively improved trunk muscle activity, balance, and activities of daily living in patients with chronic stroke.

The purpose of this study was to investigate the relation between perception of family environment and mental health of boy's high school students. In order to obtain the appropriate data, a questionnaire was administered to 240 boy's high school 2nd-grade students in Pohang city from March 19 to March 28, 1992. The instruments used for this study were Moos's Family Environment Scale Form R and Kim's Symptom Check List-90. The conclusions were as follows : The level of perception of family environment was lower than mean score. Cohesion, achievement orientation, independence, organization, expressiveness were percepted high but active-recreational orientation, intellectual-cultural orientation were percepted low. Mental health of most respondents was well. The scores of obsessive-compulsive reaction and interpersonal sensitivity were high, the scores of somatization and phobia were low. General characteristic variables significantly related to the level of perception about family environment were father's occupation and mother's education level. There were no significant differences between general characteristic variables and mental health. There were mostly negative correlations between perception of family environment and mental health. Cohesion, expressiveness, independence, intellectual-cultural orientation, active-recerational orientation, moral-religious emphasis, organization were negatively correlated but conflict, achivement orientation, control were positively correlated. Cohesion, expressiveness, conflict, achivement orientation, active-recretional orientation, organization, control were significantly related, but independence intellectual-cultural orientation, moral-religious emphasis were no significant correlation.

In order to understand how consumers' buying motivation is formed, that is the starting point of consumer behavior or consumers' decision-making processes, we examined how the interpersonal orientation for consumers is organized to control buying motivation and create a stepping-stone for subjects' behavior in fast varied consumer environments. In addition, we examined what influence this interpersonal orientation has on consumers' buying motivations. The results are shown as follows: First, interpersonal orientation is classified into six categories, according to Cohen's three types, i.e., compliance, detachment I: emotion independence, detachment II: performance independence, detachment III: perception independence, aggressiveness I: competitiveness, aggressiveness II: aggressiveness. Second, based on our inspection of the relation between interpersonal orientation and consumers' buying motivations, for external motivation and internal motivation, the value of R2 in regression seems too low to act as an influencing power on interpersonal orientation, while in case of introjected motivation, identified motivation I: self respect, and identified II: pursuit of harmony, I there seems to be some relationship.

Control independence has been put forward as a new significant source of instruction-level parallelism for superscalar processors. In branch prediction mechanisms, all instructions after a mispredicted branch have to be squashed and then instructions of a correct path have to be re-fetched and re-executed. This paper presents a new branch misprediction recovery mechanism to reduce the number of instructions squashed on a misprediction. Detection of control independent instructions is accomplished with the help of the static method using a profiling and the dynamic method using a control flow of program sequences. We show that the suggested branch misprediction recovery mechanism improves the performance by 2~7% on a 4-issue processor, by 4~15% on an 8-issue processor and by 8~28% on a 16-issue processor.

We are interested in the conditional independence in sparse $2\tims2\tims$K tables with very rare cell counts. The most popular test is Cochran-Mantel-Haenszel statistic when sample sizes are moderately large enough to guarantee the chi-square approximation. We will consider jackknifing the CMH test and also suggest an approximate normal distribution for the standardized jackknifed CMH statistic. The main focus of this paper is to improve the chi-squared approximation to the CMH test by using the asymptotic normality of the jackknifed CMH test when sample sizes are very sparse but K and N$\infty$. The performance of the proposed jackknifed test, in the sense of significance level control and power, will be compared with that of the CMH test through a Monte Carlo study.

Main starting valve is one of the main parts in the control system of diesel engines, purposed for starting main engines. It is composed of ball valve, check valve, actuator, etc. The design axioms provide a general framework for design methodology. Two axioms are independence axiom and information axiom. These axioms can be applied to all design process in a general way. The first axiom is introduced to analyze and evaluate the design of a main starting valve. The design parameters(DPS) are determined sequentially by considering the independence axiom. For the structural design of a main starting valve, the strength is calculated by using finite element method. In addition, the strength of its actuator piston is evaluated.

This paper explains how the political elites limit peruvian politics after independence, through examining the historical origin of elites, the formation of the dominant elites and their politicization in Peru, 1824-1919. In detail, the first section of this paper examines theoretical concepts and the political economic conditions of elites. The next part explores the emergence of the dominant elite group and their politicization, which is focused on economic incentives and conditions in the Guano era. Finally, this paper suggests that peruvian elite group after independence is politically motivated by the direct control of economic resources and maximized privilege in distributions of economic benefits. Furthermore, these features provided the archetype of the Peruvian politics, such as the pre-modern oligarchy and the military intervention.

For those with disabilities, the residential area is the primary place to adapt the disabilities. Since the quality of the area gives a critical impact on their quality of life, it is essential to finding the measures to create the residential environment that supports their independence. In this regard, this study aimed to compare and analyze the interior elements of the houses that hinder the independence of the physically handicapped in the rural and urban areas, and conducted a survey on a total of 80 physically challenged in Seoul and Yeongwol (40 for each area). As a result, the respondents answered that the houses where they are currently living are hindering their independence regardless of area, and there were regional differences in the level of inconvenience with the size of living room, size of utility room, location of room, lighting and heating environment, ventilation system, deteriorated wallpapers and finishing materials, threshold and floor level difference and humidity control. This study has significance by providing the realistic measures to improve the housing environment of the physically challenged living in the rural and urban areas to be customized to them to increase their quality of life.

This study aims to the influenced factor analysis of spinal cord independence measure(SCIM), on walking velocity, walking endurance, time up & go(TUG), and subject characteristics. The subject of this study were 12 persons with incomplete spinal cord injury(ASIA C, D). All subject ambulatory with or without an assistive device. All participants were assessed on SCIM(score), walking velocity(m/s), walking endurance(m) and TUG(s). The data were analyzed using independent t-test and stepwise multiple regression. The results revealed that no statistical difference was noted in subject characteristics among SCIM, walking velocity, walking endurance, TUG(p>0.5). The independence score, breathing-sphincter control and ambulation were important factors in TUG(31.4%). The results suggest that SCIM may be an inappropriate assessment tool to predict gait ability of patient with incomplete spinal cord injury. Further study about gait speed, gait endurance and TUG by change of SCIM is needed using to patient of incomplete spinal cord injury.
