The aims of this study was to investigate the effect of the Tele-rehabilitation service on health promotion and quality of life for individuals with disability. The subjects were 3 men who agreed with participating in service and were assessed of health promotion level with physical/psychological scales and quality of life. The service consists of 20 sessions for 13 weeks. The results are as follows: First, all participants improved psychosocial health promotion (subjective health level) factor. Second, physical health promotion (upper limb function, strength, range of motion) maintained and improved, but there was little change. Third, the quality of life was higher than before. In addition, qualitative research showed that participants experienced a positive change in subjective health status, emotional stability, benefit, and self efficacy, and they were satisfied with the service. Based on the results, it was shown that participation helps improve the health and quality of life of the individuals with disability in the community. This study can be used it as a basic data for establishing a Tele-rehabilitation service for individuals with disability in local community.

The purpose of this study was to investigate the relationship between job stress and coping style in college students. Participants were 314 students in a college. Data were collected using a self administered questionnaire. The survey was conducted from May 02, 2018 to May 28, 2018. There were statistically significant correlations between personality stress, family environmental stress, academic stress, school environment stress and emotion - centered coping style among sub - variables of job stress, Job anxiety stress was significantly correlated with social support seeking and emotion - centered coping style. Since college students' emotional stress coping style is related to depressive emotional and physical health problems, it is necessary to provide a psychological treatment program for early detection and coping with psychological support services, and a mixed service such as education, lecture, and camp. In addition, it is thought that strategic action skill training (plan, method, and technology) is needed to change from emotion - centered coping style to problem - solving style.

Our society has evolved into a fully connected society in a mixed reality environment enabling various knowledge sharing / management / control / creation due to the expansion of broadband ICT infrastructure, smart devices, cloud services and social media services. Therefore cyber threats have increased with the convenience. The society of the future can cause more complex and subtle problems, if you do not have an effective response to cyber threats, due to fusion of logical space and physical space, organic connection of the smart object and the universalization of fully connected society. In this paper, we propose the strategy to build knowledge-base as the basis to actively respond to new cyber threats caused by future various environmental changes and the universalization of fully connected society.

The current study aims to identify the heterogeneous changes of functional disabilities in old age rather than to identify an average longitudinal pattern and to explore the effect of health status and social status as risk factors in functional disability trajectories. The sample consisted of a representative sample of community dwellers aged 65 and older from the Korean Longitudinal Study of Ageing (2006 - 2012) was the focus of the study. Latent Class Growth Analysis was used to identify the functional disability trajectory groups. Variables regarding health status and social status changes by class were identified using multinomial logistic regression. The results showed various change patterns in functional disability, which include independent (78%), stable high (4.4%), steeply increasing (7.1%), slightly increasing (5.5%), and moderate to low (4.7%). Aggravation in depressive symptoms and cognitive functions as well as decline in social participations and social engagements were significant predictors of membership in increasing group of functional disability. The findings provide important initial empirical information to target clinical practice and have implications in the importance of conducting research on groups with different characteristics.

Monitoring technology based on electrical resistivity is widely used for non-destructive data collection and health analysis of underground structures and tunnels. Vulnerable sections such as fault zone generates many problems during construction of the tunnel. These problems cause displacement and stress changes of the ground. Therefore, it is necessary to predict the state of the fault zone section to ensure the mechanical stability of the underground structure. Monitoring the size of joints and the porosity of the fillings is essential for rocks. Previous studies have not considered the variety of fillings in rock joints. In this study, electrical resistivity tests were conducted according to the particle mixing state of the sandy fillings. When the size of fillings is decreased at the constant porosity, the electrical resistivity tends to increase. The results of this study are expected to be useful as basic electrical resistivity data for predicting the ground conditions and evaluation of the ground behavior that is containing sandy fillings in the rock joint for tunnels.

The purpose of this study was to investigate the changes that family caregivers have experienced since using the Korean Long-Term Care Insurance(LTCI) system. In-depth interviews were conducted to determine how the services offered within the LTCI program had affected family caregiving and what changes they had incurred. Results from the qualitative content analysis show that the LTCI program significantly reduced the caregiving burden among family caregivers although burdens that family caregiver perceived varied greatly depending on the types of service that the family selected, and assigned family caregivers different identities and diverse roles(i.e., service user, family caregiver, certified care provider) depending on the service they use. The phenomenon of 'certified family care provider', which was not an intention of LTCI, demonstrates the practical need of elderly persons who require both care and the comfort of family and economic status of the family. Despite the positive impact of the LTCI policy on the family caregivers' burden and family relationship, the current LTCI system should be modified in order to better meet the needs of beneficiaries and their family caregivers.

The Children's Home Inventory for Listening Difficulties (CHILD) questionnaire has been applied for assessing listening and communication difficulties in various home situations for children with hearing loss. The purpose of the study was to translate the CHILD questionnaire for parents into Korean and verify reliability and validity of Korean version of CHILD (CHILD-K). CHILD-K was completed by 55 parents of children (from ages 3~12 years) using cochlear implants (CI). Among the 55 children, 27 were in preschool and 28 in elementary. Internal consistency reliability of CHILD-K was verified by Chronbach's alpha. The mixed factorial ANOVA was conducted to compare the effects of the age group and situation factors (Quiet, Noise, Distance, Social, and Media factors) on the score of CHILD. The results indicated that CHILD-K showed excellent internal consistency reliability (${\alpha}=.96$). The CHILD scores among age groups were significantly different as the older age group resulted in higher scores in all situations except Distance. For both groups the mean scores for the Quiet situation were significantly higher than other situations, and the mean scores for the Social situation were significantly lower than other situations. Moreover, analysis showed that children with CI had difficulties in the Social situation combined with other situation factors. The results indicate that the Korean version of CHILD questionnaire is a reliable tool for the assessment of communication abilities in home situation in Korean-speaking children using CI.

The purpose of this study was to evaluate the effects of caffeine and calcium on the activities of the osteoblastic cell from mouse calvaria. The author cultured osteoblastic cells obtained from the mouse calvaria and were divided into three groups : the caffeine-treated, the calcium-treated and the combine-treated group. In caffeine-treated group, the cell toxicity was measured by MTT assay at 1, 2 and 4 days after treatment of caffeine. In all groups, the densities of the mineralized bone nodules were measured by imaging analyzer after Von Kossa staining. The alkaline phosphotase (ALP) activities were measured at 2, 7, 14, 21 and 28 days and the interleukin-1 ${\beta}$ activities at 48 hours after treatment of caffeine and calcium. The measurements were statistically executed with ANOVA test and the results were as follows. 1. The cellular toxicity of the caffeine increased with the concentration of caffeine during the incubation period. 2. The maximum densities of mineralization were observed at 0.2 mM caffeine-treated group, 1.2 mM calcium-treated group, 0.1 mM caffeine and 1.8 mM calcium-treated group. 3. The activities of ALP were peaked at 14 days at calcium-treated group as no-treated. But, the activities of ALP increased with concentrations of caffeine at caffeine-treated group. At combine-treated group, the act of ALP were peaked at 24 days at 1.2 mM, 1.8 mM calcium-treated group, But decreased at 2.5 mM calcium-treated group. 4. The activites of the IL-1 ${\beta}$ were increased significantly at 0.2 mM caffeine-treated group, 1.8 mM calcium-treated group and 0.1 mM caffeine and 1.8 mM calcium-treated group. But, they were decreased at all groups of high concentration.

Behaviors of cemented engineered soils, composed of rigid sand particle and soft rubber particle, are investigated under $K_o$ condition. The uncemented and cemented specimens are prepared with various sand volume fractions to estimate the effect of the cementation in mixtures. The vertical deformation and elastic wave velocities with vertical stress are measured. The bender elements and PZT sensors are used to measure elastic wave velocities. After cementation, the slope of vertical strain shows bilinear and is similar to that of uncemented specimen after decementation. Normalized vertical strains can be divided into capillary force, cementation, and decementation region. The first deflection of the shear wave in near field matches the first arrival of the primary wave. The elastic wave velocities dramatically increase due to cementation hardening under the fixed vertical stress, and are almost identical with additional stress. After decementation, the elastic wave velocities increase with increase in the vertical stress. The effect of cementation hinders the typical rubber-like, sand-like, and transition behaviors observed in uncemented specimens. Different mechanism can be expected in decementation of the rigid-soft particle mixtures due to the sand fraction. a shape change of individual particles in low sand fraction specimens; a fabric change between particles in high sand fraction specimens. This study suggests that behaviors of cemented engineered soils, composed of rigid-soft particles, are distinguished due to the cementation and decementation from those of uncemented specimens.
