  • Here, we introduce various type of inorganic nanostructure synthesized with functional nanoparticles and silica. From two decades ago, functional inorganic nanoparticles have been synthesized and highlighted, now we moved to next level of wet-chemical synthesis. By integrating functional nanoparticles with silica, we were able to synthesize multi-functional nanostructure, which expand the applications of nanoparticles to catalyst, drug carrier, sensors. In this context, silica has been spotlighted due to its versatility. Silica has highly biocompatible, relatively transparent and stable under harsh conditions. Thus it can be used as good supporter to synthesize complex multi-functional nanostructure when mixed with other functional nanoparticles. A various shape of complex nanostructures have been synthesized including core-shell type, yolk-shell type and janus type etc. In this paper, we have described the purposes of synthesizing silica noncomplex and various case studies for biomedical applications and self-assembly.

  • Purpose: The purpose of the study was to compare level of functional independence and its correlates among community-dwelling older adults in rural areas between South Korea and the United Sates. Methods: The study employed a comparative and correlational design. Data were collected from 198 community-dwelling older adults in rural areas (South Korea=100, & US = 98). Functional independence, cognitive function, obesity and general characteristics were measured. Results: From both countries, approximately fifteen percent of older adults living independently had cognitive problems without any treatments. Among Korean older adults functional independence was associated with a number of chronic diseases and aging while in the United States the participants had a negative correlation with obesity and aging. Conclusion: For Korean older adults in rural areas, nurses should focus on monitoring older adults' abilities to manage chronic illness and designing self-management programs while in the United States the focus should be on healthy lifestyle programs about exercise and diet to increase functional independence.

  • Functional ability is an important criterion to predict the capability of older persons to maintain independent living in the community setting. This study focused on the effect of built-environment features to ameliorate declines in functional ability and reduce the likelihood of relocation. Using longitudinal data from the Asset and Health Dynamics Among the Oldest Old (1993, 1995), relocation was analyzed for 6,225 respondents aged 70 or older. Findings are that while functional decline in household activities of daily living among older persons increased their residential moves in the community, functional declines in basic activities of daily living, household activities of daily living, and advanced activities of daily living among them increased their entrance into an institutional care facility However, they were less likely to enter an institutional care facility when their home was equipped with built-environment features such as street level ramps, special railings, modifications to allow someone in a wheelchair, grab bars or shower seat in the bathroom, and special call device or system to get help.

  • Functional MRI (fMRI) provides an indirect mapping of cerebral activity, based on the detection of the local blood flow and oxygenation changes following neuronal activity (Blood Oxygenation Level Dependent). fMRI allows us to study noninvasively the normal and pathological aspects of functional cortical organization. Each fMRI study compares two different states of activity. Echo-Planar Imaging is the technique that makes it possible to study the whole brain at a rapid pace. Activation maps are calculated from a statistical analysis of the local signal changes. fMRI is now becoming an essential tool in the neurofunctional evaluation of normal volunteers and many neurological patients as well as the reference method to image normal or pathologic functional brain organization.

  • 본 연구의 목적은 65세 이상 노인들의 참여활동수준과 ICF에 기반한 기능장애에 대해 조사하는 것이다. 도시에 거주하고 있는 노인 100명을 대상으로 하였으며, 한국형 활동분류카드(KACS)와 세계보건기구 장애평가척도 2.0(WHODAS 2.0)를 통해 자료를 수집하였다. 수집된 자료는 기술통계 및 상관분석, 다중회귀분석을 이용하여 분석하였다. 참여활동수준에 대한 조사결과, 도구적 일상생활 영역이 75.06%로 가장 높게 나타났다. WHODAS 2.0 하위영역 중 사람들과 어울리기, 사회참여 영역에 어려움이 가장 많았고, 자기관리와 일상생활활동에서의 어려움이 가장 낮게 나타났다. 참여활동 보유율과 기능장애에 대한 상관성을 분석한 결과, 모두 유의한 음의 상관관계가 있는 것으로 나타났다. 기능장애에 영향을 미치는 요인들로는 사회활동과 도구적 일상생활의 참여활동수준, 직업상태(은퇴)가 유의미한 것으로 나타났다. 연구를 통하여 참여활동수준이 기능장애를 설명하는 중요한 요인임을 확인할 수 있었다. 추후 연구결과의 일반화를 위한 표준화 연구가 이뤄질 필요가 있다.

  • This study examined the preference and the purchase intention of male and female from 20s through 405 to smart phones. This study verified the differences between the groups according to the socio-demographic factors, the usage pattern of mobile phone, and the perceived cost and the expected benefit. The analysis of the relative influence of those relevant factors was followed. The summaries of this study are as follows; First, the high level factors in purchasing smart phones were the perceived cost and the expected benefit pointed over 3.82. It means that they arc interested in smart phones highly, and if they can support to buy smart phones and situations can be permitted, they would like to buy them. Second, the differences between groups of the preference and the purchase intention were found according to the ages, the marital status and the education level. The results showed that those preference and the purchase intension were measured high at the group of the 20s-30s, the married, and the higher educational level of collage students. Third, expected benefit on smart phones was shown to be divided into two characterized factors through factor analysis. One was 'functional expected benefit' and the other was 'emotional expected benefit'. The functional and the emotional benefit on the using of smart phones were presented high level in group of over graduated students. Forth, the results of the stepwise multiple analysis, which was carried out to find out the influencing factors on the preference and the purchasing intension to smart phones, showed that the most effective factor was the functional expected benefit. The self-expressive propensity, and the education level were followed sequentially. The purchase intention was influenced by both of the functional and the emotional expected benefit. The result of this study shows that the level of the consumer's perceived cost(economic, psychological) and the expected benefit were measured high at the same time. That means that it is necessary to make the consumer information and communicating smoothly in order to lower the cost and enhance the benefit. In addition, This study has its meaning because it found out that functional expected benefit is a factor which has an influence on the Consumer Preference and Purchase Intention on Smart phone. If consumer's function requirements on smart phone are satisfied, it will be able to reduce the consumer problems and increase the consumer satisfaction. The result of this study would be applicable when Smart Phone is used as one of the auxiliary tools for smart consumption.

  • Purpose: Changes of degenerative disc have been analyzed or with the Magnetic Resonance Imaging (MRI) to assign appropriate meaning, and the relationship between the degenerative changes of the discs and its living function has been evaluated through the living function evaluation scores collected by functional rating index. Methods: in April, 2006, a physical examination was conducted for physical laborers to be employed as on-site laborer in a steel industrial complex located at a region. A month later, these 20 laborers who participated in lumbar vertebra MRI tests have been investigated for one-to-one mobile phone functional rating index test. Excluding 3 of 14 respondents whom scored 0 in functional rating index, the rest of respondents' degenerative disc grade changes shown in MRI and its relationship to living functional rating index have been performed. Results: The Dabbs method of measuring disc height resulted to show significant increase as the disc height changes from L1-2 level to L5-S1 level (p<0.01). However, there was no statistical significance with a relationship between disc height and functional rating index, and disc height average. The Magnetic Resonance Imaging analysis regard on the degree of disc degeneration and its relationship to living functional rating proved to have significant relationship (p<0.05). Conclusion: The degenerative changes monitored by Magnetic Resonance Imaging show significant relationship (p<0.05) to living function. However, this relationship could vary depend upon the characteristics of study population. So, it suggested that the future studies should be performed by considering population's age and job career.

  • Background: Patients after rotator cuff (RC) surgery experienced pain, weakness and limited of motion of the shoulder. Physical therapists have used heat therapy, electrotherapy, range of motion (ROM) exercise and other methods to treat patients after RC surgery. In addition, functional taping is also used to support joint movement and to increase shoulder joint stability. Objects: The purpose of this study was to determine the initial effects of functional taping using non-elastic tape on pain, strength and ROM of the shoulder following RC surgery. Methods: Forty-eight patients with who underwent RC surgery volunteered for this study. The subjects were randomly divided into an experimental group (EG, $n_1=25$) and a control group (CG, $n_2=23$). First, non-allergic tape was applied to the shoulder to prevent skin irritation. The EG applied functional taping using non-elastic tape and the CG applied sham taping using elastic tape. Assessment tools included the shoulder pain and disability index for functional activity score, visual analog scale for level of pain, shoulder muscle strength, hand grip strength and ROM testing. Results: Pain score in the both group significantly decreased (p<.05), and change in pain score of in the EG increased significantly than in the CG (p<.05). Shoulder strength and ROM in the both group significantly increased (p<.05). Especially external rotation and extension of the shoulder ROM in the EG increased significantly more than in the CG (p<.05), but the rate of change in the two groups showed no significant difference. Conclusion: These results suggest that functional taping using non-elastic tape was initially effective in decreasing pain score level in patients with RC surgery.

  • In developing, microscopic scale electrical and electronic devices, molecular level Insulators and functional electric conductors are fundamental. The properties of the electrical-insulating thin film materials are very much dependent on defects and electron transfer rate. There are number of companies which try to reduce defects and control electrical conductivity. Functional electrical conductors are more demanding subject in electrical fields. Reorganization energy around the sites that generate the electrons and holes are very important for the electron transfer in the organic thin layers.
