Hemiplegic patients who suffered from a stroke struggle with a deterioration in upper limb functions, which can both be psychologically and physically discomforting; this can also limit patients' daily tasks involving any upper limb motions. In this study, we developed an assistive device for hemiplegic patients to improve their upper limb functions. It was manufactured to train patients by using their grip strength and the range of motion of the arm. Furthermore, we produced game contents in virtual reality to induce users' immersion and interaction. It was configured as a multi-player game to help ease the mental burden of receiving the training alone, hence allowing the patient and the caregiver to join the rehabilitation training simultaneously. The assistive device and game contents developed in this study enables patients and caregivers to easily check the degree of improvements in upper limb function by viewing quantitative analysis and visualized results.

The purpose of this study was to investigate the relations between the cognitive functions, health conditions, activities of daily living, depression and sleep states among the elderly at care facilities. The subjects include 204 elderly people aged 65. The data collected were analyzed using descriptive statistics, the t-test, ANOVA, Pearson correlation, and hierarchical multiple regression. The findings show that the cognitive functions of the elderly at care facilities are related to their engagement in regular exercise, duration of residency, grade of care, lack of physical freedom, listening ability, state of teeth, urinary incontinence, activities of daily living, and state of sleep. Their cognitive functions had positive correlations with activities of daily living and negative correlations with state of sleep. Their cognitive impairment was significantly influenced by their engagement in regular exercise, duration of residency, grade of care, listening ability, ADL, IAD dependency, and sleep disorder. In short, the cognitive functions of the elderly at care facilities are highly related to their health conditions as perceived and felt by them. It is thus required to develop, apply, and consistently assess and manage cognitive rehabilitation training programs to provide interventions for the factors that influence their cognitive impairment.

Sickle cells possess a unique combination of traits that may enable their use as models for novel synthetic tumor targeting controlled release drug carriers with the ability to treat disseminated tumors in advanced metastatic disease. In this study, we assess the ability of light-activated release sickle cells to enhance tumor delivery of the fluorescent dye calcein by delayed photolysis controlled release compared to free systemic administration of calcein. Sickle cells from mouse models of the disease were shown to preferentially accumulate in tumors compared to adjacent tissue, in 4T1 tumors in mice on a time scale about 12 hours. Sickle cells photosensitized with protoporphyrin IX achieved delayed release of 50% of contents 8-16 hours after photoactivation, which was deemed useful for in vivo delivery of cargo to tumors given the tumor accumulation time of the sickle cells. Sickle cells may be useful as a model for new synthetic drug carrier particles with delayed photolysis controlled release properties.

This study was performed to assess the amount of altered serotonergic responsivity in individuals with repeated aggressive behaviors compared with normal controls. Sixteen aggressive(delinquent criminals with repeated aggressive behaviors) and seventeen controls(medical college students) were selected and assessed their severity of aggression by several psychological instruments. The platelet $^3H$-imipramine binding sites which is known to correlate the serotonergic function of the central nervous system were measured. The results are as follows. 1) Mean scores of physical aggression in the aggressive subjects were found to be significantly higher than normal controls(p<.01). And impulsivity, hostility, psychoticism in the aggressives were found higher than controls, also. 2) In the paltelet $^3H$-imipramine binding, the aggressives had a tendency of reduced maximal binding sites(Bmax) comparing with controls(p=.0841). 3) There was no statistically significant differences between two groups in the binding coefficients(Kd) of platelet $^3H$ Imipramine binding. 4) The value of maximal binding sites(Bmax) showed significant inverse correlations with aggressive scale scores of PFAV(r=-.6311), and physical aggression scale scores of CTS(r=-.5377).

Purpose: The purposes of this study were to assess social adjustment of childhood cancer survivors and to identify factors affecting social adjustment. Methods: Data were collected from 79 childhood cancer survivors and his/her parents. The survey consisted of questions related to characteristics, physical functioning, depression, self-esteem and coping strategies. The Social Competence Inventory was used to measure social adjustment in the children. Results: The level of social adjustment of childhood cancer survivors was 83.5 out of a possible 155. Physical functioning, depression, self-esteem, and aggressive or proactive coping strategies were associated with social adjustment. Only physical functioning independently affected social adjustment. Conclusion: The results of this study indicate that there are several factors influencing social adjustment of childhood cancer survivors, and therefore there is a need for programs that deal with all aspects of children's physical as well as emotional health in order to enhance their social adjustment.

'Tight junctions (TJ)' have recently been identified in the granular cell layer of the human epidermis, where they contribute to the normal adhesion between keratinocytes and to the physiologic barrier function of the epidermis. Among the TJ proteins in the epidermis, occludin is an important transmembrane protein, which is considered as a major component. The purpose of this study is to investigate whether regional variation exists in the expression of the tight junction protein occludin in normal human epidermis. Indirect immunofluorescence staining for occludin was performed with specimens taken from different areas of normal skin (4 from each of 7 different anatomical sites, including the scalp, face, posterior neck, upper arm, abdomen, lower back, and inner thigh). The degrees of the expression-intensity in each specimen were estimated with the reciprocals of positive end-point titer of occludin in an indirect immunofluorescence study. The highest degree expression-intensity of the TJ protein occludin among the different areas of normal epidermis was observed on the face and abdomen with a titer of 600 (p=0.001). The lowest intensity of expression of occludin was seen in the epidermis from the upper arm. Skin specimens from the scalp, neck, back, and leg demonstrated intermediate degrees of the expression in intensity. The expression of occludin in the skin samples obtained from different locations of the body showed a statistically significant variation. This suggests that there is a certain degree of regional variation in the expression-intensity of TJ protein 'occludin' in the human epidermis.

Can the appropriately programmed computer think?I analyse,in this paper, argugments for and against strong AI-thesis,basically Turing's argument and Searle's chinese room argument.Through a cirtical review of these arguments, I try to show that the supportes of Al-thesis like Turing fail to explain the subjective nature of human consciousness.However,I do not think that subjective consciousness is a necessary condition for the ability to understand language.(In this respect my views are different from Searle's). But when we consider the conditions of humans as language users,we should presuppose that a human being is the unity of body and mind (or consciousness). Therefore, our subjective consciousness,together with human body(thus,way of our behavior and life). serve as a mark of person.

This study investigated body images based on the survey data drawn from college students in three East Asian countries(Korea, Japan, and China). 347 Korean, 341 Chinese, and 271 Japanese college students responded to questions designed to measure body images such as body-related values (operability, inclination, locus of evaluation, and instrumentality of appearance), body esteem (appearance, and health), and objectified body-consciousness ( surveillance and shame). The results showed that body images differ among countries. Regarding body-related values, Korean students have least conservative beliefs and followed by Japanese, and Chinese. Korean students showed the highest acceptance level for the voluntary body alteration(operability), highest inclination to body appearance over health. They also showed the strongest tendency of evaluating their body from the observer's point of view and the strongest belief about the social utility of body appearance compare to Japanese and Chinese students. Appearance- esteem of Korean was similar to Chinese but higher than Japanese. Surveillance and shame about body appearance of Korean students were similar to Japanese but higher than Chinese. Compare to male students, females showed stronger belief about the body appearance over health, lower appearance esteem, and higher surveillance and shame about body. Korean women showed the least conservative body-related values, and the levels of body appearance esteem and objectified body consciousness were located in between Japanese and Chinese women. Japanese women showed especially low body appearance esteem and highest surveillance and shame. Chinese women showed the most conservative body-related value, the highest appearance-esteem, and the lowest surveillance and shame. It was revealed that the body-related values indirectly affect to appearance-esteem through the mediating role of objectified body consciousness in Chinese and Japanese samples, but that the body-related values had direct effect on appearance-esteem as well in Korean sample.

The aim of this study was to investigate the impact of depression, somatization, and jaw disability on graded chronic pain of TMD using Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD). Ninety-three patients (17 men and 76 women, mean$\pm$SD age of 30.1$\pm$12.5 years) diagnosed with TMD based on RDC/TMD axis I criteria were administered RDC/TMD axis II history questionnaire. The relationships between depression, somatization, jaw disability, and each parameters of graded chronic pain (e.g. pain intensity, pain days, disability score, disability days, graded chronic pain scale) were analyzed by multiple regression analysis. The obtained results were as follows: 1. Among 93 TMD patients, the prevalence of low disability group of graded chronic pain scale was 42.0% and high disability group of graded chronic pain scale was 51.5%. 2. Depression did not show any significant influences on pain intensity, pain days, disability score, disability days, and graded chronic pain scale. 3. Somatization showed a significant effect on pain intensity (p<0.01), disability days (p<0.01), and graded chronic pain scale (p<0.01) except for both pain days and disability score. 4. Jaw disability also showed a significant effect on pain intensity (P<0.001), disability days (p<0.01), and graded chronic pain scale (P<0.001) except for both pain days and disability score. Somatization and jaw disability may closely relate to the pain intensity and degree of disability that TMD patients perceive. Therefore, comprehensive understanding of psychological profile and improvement of functional limitation of jaw movements in the patient should be considered to obtain an excellent outcome of chronic TMD management.
