The purpose of this research was to study opinions on elderly housing and attitudes toward the problems related to elderly lives, which were due to dependence or independence in later life. The survey was conducted among middle-aged people in their fifties, living in Seoul. The final sample included 498 respondents. Since the statistical analysis was focused only on independent and dependent groups, total cases for the analysis were 373. The results of this study were as follows. Firstly, the group that was more independent in later life tended to be healthier, lived with a husband or wife, had no children, and had more monthly income and assets. Secondly, the group that was more independent in later life believed that they had the sole responsibility of resolving later life issues. The group that was more dependent believed that their family, not themselves, must resolve their later life problems. The independent group wanted to continue their work or enjoy leisure. Thirdly, the group that was more independent about elderly housing stated that they were responsible for it, while the other group stated that their family was. There were no significant differences between the two groups in terms of general idea, and social interest. However, the independent group answered that more development and management of elderly housing were needed. The expected living arrangement in their later lives was similar. Also, there were no differences between the two groups in living with family or the demand for service from elderly housing.

Independent Component Analysis is a popular statistical method to separate independent signals from the mixed data, and Group Independent Component Analysis is an its multi-subject extension of Independent Component Analysis. It has been applied Functional Magnetic Resonance Imaging data and provides promising results. However, classical Group Independent Component Analysis works poorly when outliers exist on data which is frequently occurred in Magnetic Resonance Imaging scanning. In this study, we propose a robust version of the Group Independent Component Analysis based on ROBPCA. Through the numerical studies, we compare proposed method to the conventional method, and verify the robustness of the proposed method.

Purpose : The purpose of this study was to analysis on diaphragm thickness and lung function of stroke patients by walking ability. Methods : We recruited thirty-five adults after stroke(20 male, 15 female) for our study. The subjects were divided into two groups; independent walking group(11 male, 9 female) and non-independent walking group(9 male, 6 female). Assessment of diaphragm thickness was performed using ultrasound in B-mode with a 7.5 MHz linea probe. During the experiment, the subject was seated in the chair. All subjects performed maximal expiratory flow maneuvers using a spirometer in order to determine the forced expiratory volume in 1 second ($FEV_1$), forced vital capacity(FVC), peak expiratory flow(PEF) and $FEV_1$/FVC. Chest expansion was measured with a tape-measure placed circumferentially around the chest wall at the xiphoid process. The collected data analyzed by independent t-test. Results : The diaphragm thickness were significant differences between the independent walking and nonindependent walking group. Values of forced vital capacity, forced expiratory volume at one second, peak expiratory flow in pulmonary function tests were significant differences between the independent walking and non-independent walking group. However, chest expansion were not significant differences in both of the group. Conclusion : This study showed that walking ability of stroke patients have influenced on diaphragm thickness and pulmonary function.

This study evaluated 26 elderly residents living independently in 4 group homes for their abilities in daily living and analyzed their behaviors of space occupancy and activities of daily living. The aim of the study was to identify the relationships between the physical environments of the group homes and the daily activities of the residents. The results of this study are summarized as follows. 1) Most residents in the group home considered bathing and cooking to be the most difficult of their living activities. The residents were categorized into "Independent," "Semi-dependent" and "Dependent" groups, on the basis of their ADL and IADL scores, and individual groups were examined. On ADL scorelt was shown, then, that 65.4% of the residents were was independent in ADL, but there was no any significant difference in IADL between the independent, semi-dependent and dependent groups. In addition, there was a difference in ADL and IADL among the groups. The independent group's residents were shown to be independent in ADL and IADL, whereas the but those of the semi-dependent and dependent groups' residents were lower in IADL than in ADL. 2) When their behaviors of space occupancy were examined, it appeared that the independent group showed a different space sharing pattern among individual residents, with a wide range of behavior of space occupancy. Meanwhile, The semi-dependent group mostly shared a common space with simple activities of daily living while no any service low leisure program was provided. However, the dependent group mainly consisted of residents who had a low level of independence in ADL and IADL, so that their behaviors of space occupancy were entirely negative.

The purpose of this study were to analysis on quality properties of lower extremity of patient with stroke by the existence of the independent walking. We recruited fourteen adults after stroke(7 male, 7 female; mean age, 64y) for our study. The subjects were divided into two groups; independent walking group(3 male, 3 female) and non-independent walking group(4 male, 4 female). We used in this study included a B-mode ultrasonography scanner with a 7.5 MHz linea probe. During the experiment, the subject was seated in the chair. The echogenicity(density, white area index; WAI) of the tibialis anterior and rectus femoris muscles were measured on both sides of the leg. In both of the density and WAI, the tibialis anterior muscle were significant differences between paratic side and non-paratic side, the independent walking and non-independent walking group. However, in both of the density and WAI of the rectus femoris muscle were only significant differences between paratic side and non-paratic side. This study showed that stroke and the independent walking have influenced on quality properties of lower leg. Especially, the independent walking has influenced on the tibialis anterior muscle.

The purpose of this study is to identify the independent tendency of single women, certainly worthy of study in considering their size, their growth, and their purchasing power, and to examine their effects on consumption values and clothing benefits. The data were collected from self-administrated questionnaire with 537 single women in their 20�s and 30�s on May in 2005. Data were analyzed by factor analysis, reliability analysis, K-means cluster, one way ANOVA and chi-square. Factor analysis on independent tendency resulted in three dimensional structures: marriage-independent tendency, physical independence, social independence. Five dimensions of consumption values were identified by factor analysis: conspicuous, pro-environmental. economic, enjoyable, aesthetic values. Five dimensions of clothing benefits were identified by factor analysis: individuality, well-known brand, practicality, price, social recognition pursuit. The respondents were classified to three groups by three factors of independent tendency: high independent group, social-physical independent group, low independent group. There were significant differences among these groups in demographic characteristics, consumption values and clothing benefits.

The purpose of this study was to explore the problem solving strategy for Goldberg machine tasks of the gifted students in elementary science depending on the cognitive style(tendency to field-dependent and field independent). It was aimed to provide suggestions for the features and differences of the problem solving strategies of the gifted students in elementary science according to their cognitive styles. A total of 16 students, from the gifted class of P elementary school in Hwaseong were sampled for the research, cognitive styles Test was conducted to divide the students in teams, and the teams were classified according to cognitive style tendencies to five groups of field-dependent group, weak field-dependent group, mixed group, weak field-independent group and field-independent group. The Goldberg device task given was to make a Goldberg device within the angle framework of (Figure) 1, for a bead to start from the starting point and to reach the final point the last. The results are as follows: First, regarding the plan for producing the device, the stronger the field-independent tendency, they established more specific strategy-reflected plan; the stronger the field-dependent tendency, they established less specific strategy-reflected plan. Second, all cognitive style groups took a limited period of time into consideration, to fabricate the devices for the ball to arrive the last using a fine adjustment rather than many devices. Third, the field-independent group used a lot of logical reasoning; the field-dependent group used a lot of intuitive thinking. Fourth, the field independent group properly utilized strategies such as cooperation and role allocation; the field-dependent group tried to solve the task personally rather than cooperatively with poor role allocation. Fifth, the intermediate mixed group solved the problem better than the inclined groups such as field-dependent or field-independent groups.

The purpose of this study is to understand the performance of the initial adaptation support program for people with mental illness living in independent housing. The group of people with mental illness living in independent housing from T mental rehabilitation facilities in Seoul were assigned to the experimental group, and the other group of people with mental illness in living facilities and group home were assigned to the control group. After that, the degree of community performance between groups was compared with pre-post tests. As a result of the study, the pre-post analysis of the total social support of the experimental group showed significant differences. Also, the results were statistically insignificant in all of the control groups, so the initial adaptation support program was found effective in improving the total social support of the independent housing group. Based on the results of this study, the direction of housing support and establishment of a performance system for housing services for stable settlement of discharged people with mental illness into the community was suggested.

This paper investigates how internal knowledge dependency and its interaction with external knowledge adoption affect innovation performance in Korean companies. We categorize innovation performance into exploratory innovation and exploitative innovation. Especially, we examine business group effects as group headquarters and sister subsidiaries holistically form the boundary of the firm. Our empirical results first suggest that the degree of internal knowledge dependency is positively associated with exploitative innovation, but negatively with exploratory innovation. Second, internal knowledge dependency is more negatively related to exploratory innovation in independent firms than in business group affiliates. Third, independent firms' adoption of external knowledge tends to strengthen the positive relationship between internal knowledge dependency and exploitative innovation. Finally, exploitative external knowledge search appears to strengthen the negative relationship between internal knowledge dependency and exploratory innovation in both types of firms.
