Purpose: The purpose of this study is to supply the basic materials for the development of objective tools to measure 'Hwa-byung' and for the development of the theories and statements associated with 'Hwa-byung' by making clear the meaning and characteristics of 'Hwa-byung' and by analyzing the concept of 'Hwa-byung'. Method: The concept analysis of Hwa-byung was proceeded according to the concept analysis process of Walker and Avant(1995). Result: The conceptual characteristics of Hwa-byung resulted from the research are like these : (1) Injustice (2) Anger (3) Rumination (4) Anxiety. Therefore, we can describe Hwa-byung as the feeling repeatedly accumulated through the heavy mental pain, injustice, and anger and it is appeared with the physical and behavioral symptoms. Conclusion: Through this concept analysis, we propose as followings ; First, there's need of the objective tools which make it possible to assess Hwa-byung through the theory development and the statement associated with Hwa-byung. Second, there's need of interdisciplinary approach in the development of nursing intervention to coordinate the characteristics of Hwa-byung by understanding the total nature of Hwa-byung and finding the variables associated with Hwa-byung.

Electric stimulators are used for various treatments, such as for pain relief and to improve rehabilitation in and out of the hospital. However, if the stimulation pulse affects the patient's heart, it can cause critical cardiac disorders such as arrhythmia or ventricular fibrillation. As a result, it must be ensured that the transmission length of the stimulation pulse does not exceed the proper range in the design of an electric stimulator. Furthermore, every anticipated risk factor must be monitored in in-vitro and in-vivo experiments. A new stimulator was designed to supply continuous 0.001 J stimulation pulses at a rate of 60 pulses per second. To evaluate the safety of the new electric stimulator and to measure its energy transfer and pulse transmission length, we built a conduction model that was filled with saline and measured the electric field at various positions in response to real stimulations. In an animal experiment with two pigs, heart disorders were induced by applying electric stimulation to tissues near the heart. These heart disorders were different from the result obtained with 9 V DC stimulation.

The aim of this study was to investigate the effect of Maitland mobilization and Kaltenborn-Evjenth mobilization on the SLR angle. Subjects randomly divided into Kaltenborn-Evjenth group(n=8) and Maitland group(n=7). The mean height, age, body weight was $176.00{\pm}5.10cm$, $22.75{\pm}1.83years$, $72.63{\pm}10.65kg$ respectively in Kaltenborn-Evjenth group. The mean height, age, body weight was $175.00{\pm}5.60cm$, $22.29{\pm}3.68years$, $78.00{\pm}12.36kg$ respectively in Maitland group. Hip joint accessary movements with Grade III or IV were applied depend on the patient's condition to the restricted direction for 1 minute each set, and performed 5 set in a Maitland group. Hip joint anteroposterior gliding with Grade III were applied 60 for 1 minutes each set, and performed 5 set in a Kaltenborn-Evjenth group. The angle of first pain was referred to as P1 and subjects were pointed out that they could not bend the knee anymore, then examiner measure SLR angle. The SLR was significantly increased in the Maitland group compared to the Kaltenborn-Evjenth group after intervention(p<.05). In a within group difference, SLR significantly increased in the both groups(p<.05). These results indicated that Maitland mobilization could be recommended the excellent technique to increase the hip flexion in patient with hip hypo-mobility.

Background: Spinal Mobilization is one of the manual therapy technique that clinicians have used to treat pain, however, there is still a lack of research on changes in strength in healthy people. Objectives: To investigate the effect of posterior-anterior lumbar mobilization on lower limb strength in healthy individuals. Design: Two-group pretest-posttest design. Methods: In this study, 23 healthy subjects aged 20 years were assigned to 12 lumbar mobilization group (LMG) and 12 sham group (SG) to perform intervention and measurement through pre- and post-design. Intervention was performed in LMG with grade III~IV on L3-5 of the lumbar spine, and lumbar mobilization was performed for each segment. After intervention, knee flexion and extension strength were measured. To measure the main effect on muscle strength, a comparative analysis was conducted using paired t-test and independent t-test. Results: In LMG, knee flexor and extensor strength were increased significantly at 60°/s (P<.05). In addition, the extensors of LMG and SG were significantly different only at 60°/s, and the flexors were significantly different between groups at both 60°/s and 180°/s (P<.05). Conclusion: In healthy individuals, lumbar mobilization results in improvement of strength of knee flexor and extensor, and additional experiments on the effect of mobilization on the lumbar spine on functional changes in the lower limbs will be needed.

This study is intended to investigate if the standard of vocational rehabilitation service could be solely determined by medical standard for disability definement and to find out what alternatives are available to resolve practical problems for those who are not identified as the severely disabled by the disability definement but do experience severe handicaps at work. Through the literature review, the researcher argued that the concept of 'functional limitation' would be a criteria, and thereby applied Modified Barthel Index to measure the degree of functional limitation. In view of researching the relationship among physical impairment, functional limitation, and job status based on 381 cerebral palsied, variables such as the type of cerebral palsy and the part of paralysis, have neither direct nor indirect influence to the job status; however, the pain and the mobility have indirect effects, and the ability of self-management has direct effect on the job status. The researcher concluded that future research about disabilities needs to provide a serious thought on what it is to be defined as 'disabilities', as well as to focus on further research conceptualizing the degree of physical 'functional limitation'.

Manual material handling(MMH)is major factor which causing physical injuries of worker at working area and frequency of low back pain(LBP) is increasing industrial accidents. Especially, working in bad circumstance such as farm, orchard, harbor loading and unloading, logging place and mining place which located in inclined slope can cause much possibility of hazard and absence of working balance can cause injuries of musculoskeletal system such as joint, bone, ligament. So, this study used EMG system to measure and evaluate muscle force information and fatigue of worker when lifting on slope. The result of measuring averaged integrated EMG(AEMG) shows multifidus muscle be used more than anything else in force. neck extensors are used at 15°, 20°frequently. generally the AEMG result shows multifidus muscle be used in force. Commonly, muscle fatigue of multifidus is higher than other muscle by analysis mean power frequency(MPF). The result of load sharing rate shows multifidus and erectorspinae which are deep spinal muscles is relatively high and neck extensor is low.

Purpose: Studies focus on cancer control, prevention, or assessment of psychosocial problems and intervention methods. However, few studies exist concerning psychosocial problems, measuring tools for those problems, and interventions for cancer patients in Korea. One of the purposes of this study was to review studies in this area, to examine various psychosocial problems experienced by cancer patients. This is a crucial area to investigate, since psychosocial problems in turn negatively influence the patients' immune function, which speeds the progress of the disease. Another goal was to identify instruments used to measure psychosocial functioning and problems in cancer patients, to analyze their validity and reliability, with the aim to discover the best instruments. A final goal was to explore and compare the effects of psychosocial interventions, to determine the most effective practices. Method: Journal articles published since 1995 were searched from PubMed Data base, Google search engine, and published cancer-related studies, using search keywords "psychosocial function and intervention for the cancer patients"; whole articles of selected references were reviewed and analyzed. Result: Most common psychosocial problems were depression, fatigue, nausea, pain, distress, resulting in a low quality of life. The seven scales found in the literature to assess the psychosocial functioning were Center for Epidemiological Studies-Depression, State-Trait Anxiety Inventory, Symptom Checklist 90-R, Profile of Mood States, Psychosocial Adjustment to Illness Scale, Brief Symptom Inventory, and SF-36 HRQOL(Health Related Quality of Life). Social support interventions for cancer patients were effective in improving quality of life scores. Conclusion: It is necessary to apply support intervention strategies to help cancer patients in Korea. These strategies can help to reduce the effects of psychosocial symptoms, which in turn affect the development and control of cancer. Strategies developed in Western countries may need to be modified for use within Korea. Further studies are warranted to review the support intervention strategies that were being used to for cancer patients

Therapeutic ultrasound which is developed for rehabilitation therapy have already been used for healing joint contracture, synechia, acute and chronic inflammatory diseases. Medical devices for pain-relief and healing using therapeutic ultrasound are actively being developed. This study measured the change of PTT with the transmitted ultrasound through the human body to find out the increase of compliance of blood vessels. Measurement method of PTT in this study is employed as useful ways to acquire physiological information of patients in the clinical case in order to measure the change of mechanical characteristics of blood vessels. This study confirmed the PTT change of rehabilitation patients through the thermal effects of ultrasound by using PTT and also found that it is possible to increase PTT by adjusting the warm water and ultrasound. The increase of PTT means the decrease of the pulse wave velocity from the cardiovascular system to the peripheral arteries. The physiological effects occurred using the warm water and ultrasound.

Background: Resilience engineering is a paradigm for safety management that focuses on coping with complexity to achieve success, even considering several conflicting goals. Modern sociotechnical systems have to be resilient to comply with the variability of everyday activities, the tight-coupled and under-specified nature of work, and the nonlinear interactions among agents. At organizational level, resilience can be described as a combination of four cornerstones: monitoring, responding, learning, and anticipating. Methods: Starting from these four categories, this article aims at defining a semiquantitative analytic framework to measure organizational resilience in complex sociotechnical systems, combining the resilience analysis grid and the analytic hierarchy process. Results: This article presents an approach for defining resilience abilities of an organization, creating a structured domain-dependent framework to define a resilience profile at different levels of abstraction, and identifying weaknesses and strengths of the system and potential actions to increase system's adaptive capacity. An illustrative example in an anesthesia department clarifies the outcomes of the approach. Conclusion: The outcome of the resilience analysis grid, i.e., a weighed set of probing questions, can be used in different domains, as a support tool in a wider Safety-II oriented managerial action to bring safety management into the core business of the organization.
