신체는 연령이 증가하면서 자세조절에 관여하는 고유수용성 감각, 시각, 전정기능이 감소하고 근력이 약해지고 갑작스런 움직임의 변화에 대처하는 반사능력이 감소하여 균형조절에 영향을 주고 낙상을 유발하는 원인이 된다. 균형조절의 어려움은 낙상에 대한 두려움으로 인하여 낙상효능감에 영향을 주고 독립적인 일상생활에 많은 장애를 일으킨다. 본 연구는 요양원에 입소한 65세 이상의 노인을 대상으로 가상현실 프로그램이 노인의 정적균형 조절과 낙상효능감에 미치는 효과에 대한 연구이다. 연구방법은 65세 이상 노인 14명을 대상으로 하여 가상현실군(n=7)과 대조군(n=7)으로 매회 30분씩, 총8회 실시하였다. 가상현실군은 일반적 운동치료법근법과 가상현실 프로그램을 실시하였고, 대조군은 일반적 운동치료접근법을 실시하여 치료 전·후를 평가 비교하였다. 대상자의 정적균형 조절과 낙상효능감은 Bio-Rescue와 낙상효능감척도로 평가를 하였다. 결과에 따른 자료 분석은 Wilcoxon signed test와 Mann-Whitney U test를 실시하였다. 연구의 결과 가상현실군이 정적균형 조절 평가에서 눈을 뜬상태에서의 정적균형 조절이 향상되었으며, 안정성 한계 변화에서 움직임의 범위가 증가하였다. 낙상효능감의 변화에서도 증가하였다. 결론적으로, 가상현실 프로그램은 노인에게 정적균형 조절과 낙상효능감에 효과가 있으며, 노인에게 가상현실 프로그램을 이용한 다양한 치료 방법과 치료에 대한 객관적인 평가가 필요하다고 사료된다.

Objective: To explore changes in the serum tumor makers, hypoxia-inducible factor-$1{\alpha}$ (HIF-$1{\alpha}$) and vascular endothelial growth factor (VEGF) level and their relations in patients with non-small cell lung cancer (NSCLC) before and after intervention. Materials and Methods: Forty patients with NSCLC and 40 healthy individuals undergoing physical examination in our hospital provided the observation and control groups. HIF-$1{\alpha}$ and VEGF levels in serum were detected by enzyme-linked immuno-sorbent assay (ELISA) in the observation group before and after intervention and in control group on the day of physical examination, along with serum carcino-embryonic antigen (CEA), neuron-speci ic enolase (NSE) and squamous cell carcinoma antigen (SCC) levels in the observation group with a fully automatic biochemical analyzer. Clinical effects and improvement of life quality in the observation group were also evaluated. Results: The total effective rate and improvement of life quality after treatment in observation group were 30.0% and 32.5%, respectively. Serum HIF-$1{\alpha}$ and VEGF levels in the control group were lower than that in observation group (p<0.01), but remarkably elevatedafter intervention (p<0.01). In addition, serum CEA, NSE and SCC levels were apparently lowered by treatment (p<0.01). Serum HIF-$1{\alpha}$ demonstrated a positive relation with VEGF level (p<0.01) and was inversely related with CEA, NSE and SCC levels (p<0.01). Conclusions: Significant correlations exist between marked increase of serum HIF-$1{\alpha}$ and VEGF levels and decrease of indexes related to hematological tumor markers in NSCLC patients after intervention.

A mechanical system controlled by human operator, such as master-slave system, includes human dynamics in the whole system and such a system is called a human-machine system. In the system, operator's skill is required considerably in order to realize a meaningful operation. In this paper, a new concept and design strategy of compensator that improves the operativity of human-machine system are proposed. The compensator is called "collaborater "that is named after "collaborator" who works together with people. We mean not to design the automatic controller but the compensator that works together with a machine so that human feels the fulfillment in the operation. Our aim is to realize cooperation of people and a machine on a higher level.

Nine districts in Seoul were chosen randomly and a questionnaire containing 23 questions was distributed to survey the perception of noise pollution by the citizens. The results were primarily analyzed to understand the perception of Seoul citizen as a whole, and then analyzed according to 4 demographic variables -district area, age, gender and occupation -to see if there were any possible relation between nonnoise variables and noise annoyance. Actual noise level data measured by the city government were used to compare quantified noise level with the surveyed people's perception. It was found that people consider road traffic noise to be the naix source of noise pollution In Seoul and that most people have experienced annoyance in everyday life. Also it was verified that the responsibility for noise control should be on both city government and the individuals, but It was generally considered that very little effort Is actually put Into solong norse pollution from both groups. From the survey, It could be analyzed that domographic variables do affect people In the awareness of noise pollution, and that one's sensitifty and annoyance due to noise increase as one ages. From the study, It was concluded that noise pollution Is not considered currently as a hazardous problem to most Seoul citizens, however specific noise reduction policies, especially regarding road traffic noise, should be put Into practice In the near future.

Purpose: This research was carried out to examine if music therapy is effective in decreasing elderly people's depression level and in increasing their life satisfaction level Methods: This study used the quasi-experimental design with nonequivalent control group and the pre-test and post-test design, and was conducted from the 26th of July to the 26th of September in 2004. Data were collected using a questionnaire developed by Y.esavage et al. (1983) to measure depression level and one developed by Yoon (1982) to measure life satisfaction level. The subjects were 80 elderly people who were the members of an elderly welfare center in G city. The subjects were divided into an experimental group (n=40) and a control group (n=40). Results: The first hypothesis 'The depression level will be lowered in the experimental group who received music therapy' was supported (t=3.856, p=.000). The second hypothesis 'The life satisfaction level will be raised in the experimental group who received music therapy' was supported (t=2.040, p=.045). The results above suggest that music therapy can be an effective nursing intervention for reducing the depression level and increasing the life satisfaction level of elderly people.

Purpose: The purpose of this study was to explore the stress-coping process used by elderly people. Method: This study was based on the grounded theory methodology of Strauss & Corbin. The participants were 15 elders selected by theoretical sampling. Over a period of 3 months, in-depth interviews using audiotape recording were used to collect the data. The data were analyzed simultaneously by a constant comparative method in which new data were continuously coded in categories and properties according to Strauss and Corbin's methodology, Result: Stress in elderly people is caused by illness, family conflict, and loss of economic power. Stress occurred in connection with aging and limitation of social activity. The central incidents for stress were fear, alienation and anxiety. It was found that action/interactional strategies of stress-coping behavior were related to social support and mobility disorders. Action/interactional strategies to stress-coping in elderly people were dependent on medical treatment, mind control, participation of social activity, and renunciation of offensive behavior. Stress-coping in elderly people resulted in stability or instability in body and mind. Conclusion: It is suggested that the results of this study may contribute to the development stress-coping strategies for elderly people. There is need to develop social support systems and a positive environment to avoid negative coping strategies.

Purpose: This study was conducted to contribute on nursing practice for elderly people by identifying the effects of hand moxibustion and hand press pellet therapy on the alleviation of constipation. Methods: The data were collected from October to November, 2009, and the subjects included 39 elders (experimental group: 20, control group: 19) from a senior citizens center in B City who reported constipation. Experimental group received an intervention of hand moxibustion and hand press pellet therapy three times a week for six weeks (total: 18 times). Data about the number of defecations per week and constipation degree scores were collected one week after each treatment. Results: 1. The number of defecation in the experimental group were different from that of the control group (F=228.26, $p$ <.001). 2. The degree of reported constipation in the experimental group differed from the control group (F=170.59, $p$ <.001). Conclusion: Hand moxibustion and hand press pellet therapy was shown to be effective in alleviating the constipation of elderly people by increasing the number of defecation per week and reducing the constipation degree scores. These two interventions can thus be used for alleviating the constipation of elderly people, replacing the stool softener and enema.

For elderly people, an advanced training machine that uses actuator and can adjust load according to muscle activity is proposed. The proposed machine allows users to have a safe and effective training through exercise close to ordinal motion appears in daily life such as stretching or stooping motion. A muscle activity sensor real-timely monitors the activation level of user's muscle during the exercise and the training load is adjusted based on the measured data. The training load is exerted and continuously controlled by electric/pneumatic actuator.

Recommendations for older driver-friendly automobile interior design have been determined by taking into account older people's physical and cognitive characteristics. Twenty three older people (aged from 54 to 78) and five younger people (from 20 to 29) performed several tasks in actual driving conditions, in which their reaction times and performance errors were recorded. Some design factors were found to be related to older drivers' visibility and controllability. Several design recommendations were proposed in terms of cluster color and font, display location, and HVAC control type. Proposed recommendations are expected to satisfy a wider range of older drivers as these will facilitate automobile interior designs which are fitter to older drivers' visual, cognitive, and manual capabilities.
