The established gait analysis studies have regarded leg as one single spring. If we can design a knee-ankle actuating mechanism as a primary actuator for supporting knee extension, it might be possible to revolutionary store or release elastic strain energy, which is consumed during the gait cycle, and as a result leg stiffness is expected to increase. An ankle joint actuating mechanism that stores and releases the energy in ankle joint is expected to support and solve excessive artificial leg stiffness caused by the knee actuator (primary actuator) to a reasonable extent. If unnecessary kinematic energy is released with the artificial speed reduction control designed to prevent increase in gait speed caused by increase in time passed, it naturally brings question to the effectiveness of the actuator. As opposed to the already established studies, the authors are currently developing knee-ankle two actuator system under the concept of increasing lower limb stiffness by controlling the speed of gait in relative angular velocity of the two segments. Therefore, the author is convinced that compensatory mechanism caused by knee actuating must exist only in ankle joint. Ankle joint compensatory mechanism can be solved by reverse-examining the change in metatarso-phalangeal joint (MTPJ) tilt angle (${\theta}_1=0^{\circ}$, ${\theta}_2=17^{\circ}$, ${\theta}_3=30^{\circ}$) and the effect of change in gait speed on knee activity.

The environment in the ICU leads to negative changes in a patient's usual sleep pattern and so contributes negatively to the patient's health condition as compared to patients in general wards. Therefore, it is thought that an important nursing intervention would be to identify the relation between noise and sleep patterns which play an important role in illness recovery. The purpose of the present study was to explore the relationship between noise in the ICU and the sleep pattern of patients admitted to the ICU. A descriptive correlation design was used to examine the relationship. Thirty-four subjects were recruited from a Medical ICU (MICU), Surgical ICU (SICU) and Coronary Care Unit (CCU) at a large university hospital in Suwon. Data were collected from September 28 to October 31 in 1999. In the present study, noise was categorized into noise level and patients' perception of noise. The objective noise level was measured using the A-Weighted Sound Level Meter. The patients' preception of noise was measured using a self-reported questionnaire developed by the researcher. Sleep patterns in this study includes both quantity and quality of sleep. These were measured using open ended questionnaires and the 'Korean Sleep Scale A' developed by Oh, Song, Kim(1998). The data was analyzed using the SPSS-WIN to test the research question, Pearson product moment correlation coefficient was run. Ancillary analysis were conducted with demographic variables to determine their relation to the main study variables. For the ancillary analysis, t-test and one-way ANOVAs were performed. The results of the present study are summerized as follows : 1. The total mean of objective noise level (10pm-6am) was 56.2dB. The means for night time noise level in individual ICUs for the SICU, MICU and CCU, were 58.7dB, 58.6dB and 48.3dB, respectively. The total mean for patients' noise perception was 42.8 out of a maximum possible score of 76. For item means of noise perception, the one ranked highest was "conversations between doctors and nurses" (3.2). The one ranked lowest was "noise from the radio" (1.2). Regarding the degree of perception for each type of noise source, the one ranked highest was "equipment noise" (2.6), the second was "conversation between medical staff" (2.4), the third was "conversation between patients, caregivers and visitors" (2.3), and the one ranked lowest was "environment noise" (1.8). 2. Looking at quantity of sleep of ICU patients, the mean nocturnal sleep time was found to be 4.9 hours. The total mean of sleep quality for ICU patients was 21.0 out of a maximum possible score of 40. 3. The relationship between perception of noise and quantity of sleep was statistically significant(r= - .41, p<.05). The relationship between perception of noise and quality of sleep was also statistically significant(r= - .47, p<.01). The results of the study indicate that personal perception of noise is related to sleep patterns. Therefore, it is suggested that nursing interventions be developed to reduce the degree of personal perception of noise and, thus, decrease sleep pattern disturbances in patients in the ICU.

This study was to assess the effects of a recovery oriented integrated rehabilitation program on cognitive social function, rehabilitation motivation, and mental health recovery. This program is involved motivation enhancement program with 4 subprograms composed of cognitive rehabilitation, emotion management, vocational rehabilitation, family education program. The subjects were 34 patirents with schizophrenia who had been hospitalized at National Mental Hospital on local area. The study was a non-equivalent control group non-synchronized design with two groups, an experimental group(18 patients) and a control group(16 patients). The collected data were analyzed using SPSS 12. 0. The results of the data show that there was not a significant increase in the symptom, cognitive and social function. But there was a significant increase in readiness of rehabilitation(maintenance, p=.027) and mental health recovery (p=.039). Short term recovery oriented integrated rehabilitation programs in inpatient settings are more available for motivation of rehabilitation and mental health recovery than symptom reduction or functional improvement. Therefore there should be more efforts to create more recovery oriented service provision in clinical settings.

This study is a nonequivalent control group pre- and post-test design research whose purpose was to determine what effects the pre-operation provision of information has on the anxiety and uncertainty of mothers with a pre-school child of tonsillectomy and nursing satisfaction after the operation. Data were collected from mothers whose child underwent tonsillectomy at S general hospital. For the collection, those mothers were divided into the experimental and control groups, respectively consisting of 19 and 20 members. The experimental group was provided general education about the operation. In addition, they individually received information about the procedure that the researcher and an assistant provided on one-to-one basis for about 20 minutes, in which brochures containing the information were used. While, the control group was provided only general education as mentioned above. For data analysis, this study conducted ${\chi}^2$-test, Fisher's exact test and Mann-Whitney U-test. The pre-operation provision of information was found having brought significant differences between the control and experimental groups in their anxiety(U=104.5, p=.015) and uncertainty(U=83.5, p=.002) as well as their satisfaction after the operation(U=109.5, p=.022). The findings of this study strongly suggest that information provision before the operation is positively effective in reducing the anxiety and uncertainty of mothers with a tonsillectomy child and increasing their nursing satisfaction after the operation. These effects need to be more verified through repetitive and subsequent researches and by using many other methods of information provision.

In the multimedia tele-medical system the medical informations are stored and managed in multimedia database. Also, multimedia DBMS is essential in order to manage large scale medical informations, and the remote access function is necessary for the distributed processing at all around the hospital. For the multimedia tele-medical information that is composed of image/picture, data, video, and audio, a high-speed telecommunication network is necessary that can provide separated connections for each medical information type with different QoS. The commercial DBMSs are based on the TCP/IP socket API(Application Programming Interface) that does not provide multiple QoS. Also, each commercial DBMS has its own API that is incompatible with other DBMS. In this paper, we propose a multimedia DBMS agent for the remote access of the multimedia database in the tele-medical system. The proposed multimedia DBMS agent is based on the ATM API that can provide high-speed data transfer capability and multiple QoS connections. Also, the proposed multimedia DBMS agent is independent of the commercial DBMS. We explain the functional architecture of the multimedia DBMS agent, implementation technology on the ATM network environment, and the result of performance analysis.

Recently attention has been focused on the effects of early intervention, or its lack, on both normal and preterm infants. Particularly numerous studies suggest that premature infants are not necessarily understimulated but instead are subjected to inappropriate stimulation. Developmental support and sensory stimulation have become clinical opportunities in which nursing practice can impact on the neurobehavioral outcome of premature infants. Developmental care has been widely accepted and implemented in neonatal intensive care units across the country. Increasingly, attention and concern in caring for low-birth-weight infants and premature infants has led clinicians in the field to explore the effects of a complex of interventions designed to create and maintain a developmentally supportive environment; to provide age-appropriate sensory input; and to protect the infant from inappropriate, excessive and stressful stimulation. The components of developmental care include modifications of the macro-environment to reduce NICU light and sound levels, care clustering, nonnutritive sucking, and containment strategies, such as flexed positioning or swaddling. Sensory stimulation of the premature infants is presented to standardize the modification of a developmental intervention based on physiologic and behavioral cues. The most appropriate type of stimuli are those that are sensitive to infant cues. Evaluation of infant physiological and behavioral responds to specific intervention stimuli may help to identify more appropriate interventions based on infants' cues. A critical question confronting the clinician is that of determining when the evidence supporting a change in practice is sufficient to justify making that change. There are acknowledged limitations in the current studies. Many of the studies examined had small sample sizes; used nonprobability sampling; and used a phase lag design, which introduces the possibility of threats to internal validity and limits the generalizability of the results. Although many issues regarding the effects of developmental interventions remain unresolved, the available research base documents significant benefits of developmental care for LBW infants in consistent outcomes, without significant adverse effects. Particularly, although the individual studies vary somewhat in the definition of specific outcomes measured, instrumentation used, time and method of data collection, and preparaion of the care providers, in all studies, infants receiving the full protocol of individualized developmentally supportive care had improvements in some aspect of four areas of infant functioning: level of respiratory or oxygen support, the establishment of oral feeding; length of hospital stay, and infant behavioral regulation. In summary, based on the available literature, individualized developmental intervention should be incorporated into standard practice in neonatal intensive care. And this implementation needs to be coupled with ongoing research to evaluate the impact of an individualized developmental care programs on the short- and long-tenn health outcomes of LBW infants.

This study was performed to examine the effect of a 7-week comprehensive health promotion program for improving pain, depression, and disability by employing a quasi-experimental design. The subjects were regular out-patients of a RA aclinic in an University Hospital in Inchon from November 11. 1998 to December 24. 1998. The Experimental group included 18 patients who participated in an arthritis health promotion program, and the control group included 18 patients who did not. The 7-week health promotion program, which had the objective to enhance health promoting skills, was provided to patients. The effects of this program on the patients' pain, depression, and functional disability were examined. According to the study results, a significant group difference was found on these dependent variables (Hotelling's T =.30, F=3.11, p=.04). To examine which dependent variables had significant effects, one-way ANOVAs were performed. There were significant group differences in pain (F=4.35, p=.05) and in depression (F=4.22, p=.05) However, no significant group differences on functional disability (F=.04, p=.84) were found. Conclusively, the arthritis health promotion program, which was designed to enhance 11 health promoting skills, can be evaluated as successfully achieving the ultimate goal of enhancing the patients' quality of life. It can also be contended that the improvement of the patients' quality of life was enabled by relieving pain and reducing depression.

This study is aimed at developing a cardiac rehabilitation program and enlightening the effects of the program on patient's health behavior compliance, cardiovascular functional capacity, and quality of life. Using a quasi-experimental approach the nonequivalent control group pretest - posttest design was accepted for this study. The subjects of this study consisted of 55 patients with ischemic heart disease at the Cardiac Center of 'G' Hospital located in Inchon from May 1, 1998 to April 30, 1999. The patients were divided into two groups: the experimental group, which participated in the cardiac program with 30 patients and 25 patients of a control group were not involved in the program. There were two phases in the cardiac rehabilitation program: the first phase was a team approach education. It focused on reducing the risk of ischemic heart problems. The second phase was individual training by using a home based exercise program, which was comprised of 8 weeks, three sessions per week, 40-60 minutes per session, and followed by consultation. Every session involved 20-40 minutes of aerobic exercise at 40-60% of heart rate reserve, 11∼13 RPE and 10 minutes of warm-up and 10 minutes of cool-down exercises. The experimental tools for the study were the health behavior compliance scale developed by Lee, Yoon-hee (1992), and quality of life scale developed by McGirr et al.(1990). RPPsubmax were measured by the treadmill. The collected data was processed by SPSS and analyzed by χ²test and t-test. The results of this study were as follows: 1. The health behavior compliance in experimental group was significantly increased (t=5.091, p=.000) when compared to the control group. 2. RPPsubmax also decreased significantly in the experimental group when compared to the control group(t=-2.109, p=.040). 3. The quality of life significantly improved in the experimental group (t=3.853, p=.000) as compared to the control group. As the above results of this study revealed, the effectiveness of the cardiac rehabilitation program of the study was confirmed. It increased the health behavior compliance for reducing the risk of further coronary events, enhanced the cardiovascular functional capacity, and eventually improved the patient's quality of life.

This study was executed to introduce a greenhouse style "Evergreen Park" to apartment complexes to target hands-on resident participation and application rather than a mere viewing of the plants as a way to provide convenient and profitable service to residents in a year-round center of usable outside space. The four key points can be summarized as follows: first, subtropical plants are evergreen broad-leaved trees, which maintain their green during all four seasons the leaves are thick and glossy. Greenhouses geared toward these subtropical trees-mainly broad-leaved evergreen species-are in planning to introduce these unique, elegant plants to temperate regions. Residentswill not only gain an education regarding these species but will be provided with the best quality evergreens at very reasonable maintenance costs. Second, subtropical plants greenhouses introduced in apartment complexes are suggested for structures connected via underground passage as well as free-standing structures so as to make use of geothermal heating and apply to reducing sunlighting. Third, as a way to provide (1) health & relaxation(evergreens, herb garden, water space), (2) community & education (plant flea market/plant hospital, plant-related lecture(exhibition), hands-on experience program), (3) a vine garden for year-round use such festivities as a Butterfly Festival, Aroma festival, Smile Oak Nuts, Candlelight Festival and Christmas Photo Site. Lastly, it has been suggested that the operation and maintenance of these greenhouses will be both by resident council operation management and by outsourcing company operation management.
