Objective: This study aimed to compare muscle structure, balance, and gait parameters between healthy adults and persons with stroke and to analyze the correlation among these variables. Design: Cross-sectional study. Methods: Twenty persons with stroke (11 male, 9 female) and twenty healthy participants (9 male, 11 female) were included. Ultrasound images of the triceps surae and the tibialis anterior were acquired in sitting resting, sitting co-contraction, and standing resting positions and also during the functional reach test (FRT) and single leg anterior reaching test (SLART). Muscle thickness and fascicle length were measured. Spatiotemporal parameters of gait were measured using a pressure walkway. Gait speed, cadence, step length, stride length, stance time, and swing time were measured. Results: Changes in percent fascicle length were significantly greater in the gastrocnemius and soleus (SOL) muscles of healthy adults in the sitting co-contraction position (p<0.05). The percent fascicle length of the SOL in FRT and SLART were significantly greater in healthy adults (p<0.05). The mid-stance phase of stroke patients was shorter than healthy adults (p<0.05). A negative correlation was observed between percent fascicle length of the SOL in the sitting co-contraction position and the proportion of the mid-stance phase (p<0.05). Conclusions: The function of the triceps surae is affected in persons with stroke when compared with healthy adults. This can lead to difficulty in performing tasks that involve forward transfer of weight. If the triceps surae is not sufficiently secured, the possibility of compensation in the stance phase increases during gait.

Many concerns have been raised for importance of disaster management after 1990's numerous urban disasters in Korea. When the primary function of government is to protect lives and property of citizens, disaster management should be included in the mainstream of public administration and many hazard countermeasures should be carried out for that purpose. The principal purpose of this research is to establish ways and means needed to improve the disaster management system in Korea. This paper is split into five chapters. Chapter I is the introduction part. Chapter II introduces the reader to a disaster management theory, and deals with various disaster management systems of foreign countries such as the U.S.A. and Japan, Chapter III describes and characterizes the Korea's current disaster management system. The Korean disaster management system has been reestablished through the enactment of the Disaster Management Act of 1995 and the full revision of Natural Hazards Management Act of 1995 after series of catastrophic man-made disasters since 1993. Chapter IV is devoted to the establishment of an effective disaster management system in Korea. In this chapter, I discusses measures needed to improve the quality of CDMB(Central Disaster Management Bureau)'s service to the people. I strongly reemphasize the effectiveness of a comprehensive risk-based, all-hazard national emergency management system that addresses preparedness, mitigation, response, and recovery. To that end the Administration should develop legislation, new policies, and organizational plans to invigorate the agency with a refocussed mission. Chapter V is a conclusion. As the demand for citizens'welfare has been continuously increased in the localization, the importance of disaster management is emerging subject in the public sector. The disaster management carries out complicated affairs and manages diverse objects, the cooperation/connection system of the central-local government and citizens, and non-governmental organization should be established.

Korea Institute for Family Planning (KIFP) was established on July 1, 1971 (Law 2270) and Korea Health Development Institute (KHDI) was established on April 19, 1976 (Law 2857). Korea Institute for Population and Health (KIPH) was formed through the merger of KIFP and KHDI (Act 3417) on July 1, 1981. Korea Institute for Health and Social Affairs (KIHASA), the former KIPH, was renamed KIHASA on December 30, 1989 (Law 4181) with its additional function of research in social security. It was transferred on January 29, 1999 to the Office of State Affairs Coordination pursuant to the Law on the Establishment, Operation and Promotion of State-Sponsored Organizations (Law 5733). Annually it conducts approximately 50 short- and long-term research projects to accumulate a wide range of research experience. Also it studies and evaluates the primary issues of national health services, health and medical industries, social insurance, social security, family welfare, and population. it conducts joint research projects and active information exchange programs with related domestic and international organizations through seminars and conferences. It executes specific research and development projects according to the government's requests. it educates and trains people domestically and abroad by disseminating a wide-range of information on health and social affairs. it conducts national household surveys on areas of fertility, health and medical care of the disabled, the elderly, and low-income earners. The mid- and long-term research goals of KIHASA should be established and managed systematically. A new organization such as 'Center for Policy Evaluation' is needed to enhance research abilities and experiences. Able research personnels should be recruited and current researchers should try to develop their abilities.

The purpose of this study is to investigate the effects of work-family conflict and spousal support resources on parenting stress among working mothers with pre-school children. This study involved a total of 232 working mothers with children enrolled in child care centers in Seoul and Gyeonggi-do as conducting a survey. First, the higher the work-family conflict (inter-role conflict caused by the impact of work on family life), the higher the family-work conflict (inter-role conflict caused by the impact of family life on work). Moreover, the lower the level of spousal support resources (emotional spousal support resources, instrumental spousal resources), the higher the work-family conflict and family-work conflict. The level of parenting stress was higher in working mothers experiencing greater work-family conflict and family-work conflict both and lower levels of spousal support resources for parenting. Second, the number of children and the amount of work-family conflict and instrumental spousal support resources had a statistically significant impact on parenting stress. Thus, the higher the number of children, the greater the work-family conflict, and the lower the level of instrumental spousal support resources, the higher the level of parenting stress. The findings of this study highlight the relative effects of role conflicts between work and family and of spousal support resources on parenting stress in working mothers. Husbands' being involved in parenting, in particular, was identified as an important support function for healthy child-rearing by successfully combining career and family responsibilities.

This study was designed to examine the relationship between clinical symptoms, self-efficacy, and performance of women with osteoarthritis. It is a survey study of 60 women who were diagnosed as osteoarthritis and given medical treatments from September, 2005 to October, 2005 in hospital 'H' located in Yongin-si. For clinical symptoms, radiographs of the subjects' knees were taken and evaluated the pathology grade by the Kellgren-Lawrence grade. Pain and stiffness was measured by the measure of WOMAC (Western Ontario and McMaster Universities Osteoarthritis Index), and functional reach test was measured in order to examine balancing abilities. Self-efficacy was measured by a tool which has revised the ASES (Arthritis Self-Efficacy Scale), and performance was measured by recording the difficulty of the WOMAC measurements themselves, and the time taken for 20 m walking, going up and down 9 stairs, and 5 sit-down and stand-up repetitions. The resulting differences in the other variables according to performance and the relationship between performance with variables are the following. First, an increase in pain in women with osteoarthritis led to decreased functional ability. Second, an increase in stiffness in women with osteoarthritis led to a decrease in functional ability. Third, a decrease in balance in women with osteoarthritis led to a decrease in functional ability. Fourth, a decrease in self-efficacy in women with osteoarthritis led to a decrease in functional ability. Fifth, the variables for estimating the performance by self-report were pain and self-efficacy. The variables for estimating the performance by recording the time taken was balance and self-efficacy. As a result factors such as pain, balance and self-efficacy in women with osteoarthritis were closely related to performance. Based on the results, it seems that physical therapy programs to decrease pain and to increase the balance in women with osteoarthritis, and psychological approaches to increasing self-efficacy are needed. I hope that the results of this study will be useful data for clinical management and intervention for women with osteoarthritis.

Background: Although the original version of the health-related quality of life (HRQOL) questionnaires are found to be acceptable, the cross-culturally adapted versions may not be comparable to their original version. Objects: To examine dimensionality and construct validity of two Korean versions of the brief version of the World Health Organization Quality of Life (WHOQOL-BREF) and EuroQOL-5 dimension (EQ-5D) questionnaires. Methods: A total of 77 cancer survivors undergoing palliative rehabilitation programs from two rehabilitation institutes was recruited from April 16, 2018 to June 26, 2019. The WHOQOL-BREF and the EQ-5D were filled out by the various cancer survivors following a particular session of rehabilitation programs. The scores were analyzed with Winsteps Rasch analysis computer program using the rating scale model. Rasch fit statistics were used to determine the dimensionality and the item difficulty calibrations of WHOQOL-BREF and EQ-5D. Results: All items except two, negative feeling, need treatment function and pain prevent activity (mean square [MnSq] = 2.42, 1.82 and 2.51, respectively), were found to be acceptable, while two items of the EQ-5D, anxiety/depression and self-care, were misfit (infit MnSq = 1.65 and 0.38, respectively). Item difficulty calibrations of WHOQOL-BREF match person ability measures (i.e., HRQOL) fairly well. However, the person ability distribution showed obvious ceiling effects for EQ-5D. All items of EQ-5D were appeared to be less challenged in comparison with those of WHOQOL-BREF. Conclusion: Item-level analysis using the Rasch model supports the quality of culturally adapted items used to measure the HRQOL one exception; that is, whether or not to include misfit items as part of the HRQOL measurements. Additionally, cancer survivors undergoing palliative rehabilitation programs appear to have more of a tendency to view the EQ-5D items as being more challenging than the WHOQOL-BREF.

Purpose: Hemiplegia patients who were attacked by a stroke suffer from hemiplegic disabilities as well as motor disabilities. For them, rehabilitation cure is being carried out broadly. However, it is not enough for them to use the upper extremity than the lower extremity. For the use of the upper extremity, we examined the effect of constraint-induced movement therapy developed in this research on patients who experienced a stroke following hemiplegia. Method: For this study we selected 36 stroke patients who were registered at the community health center through accidental sampling, and assigned 21 of them to the experimental group, and 15 to the control group. The experimental group had constraint-induced movement therapy for 5 days and 7 hours a day from 9 to o'clock in the morning 9 to 4 o'clock in the afternoon 4 including warmup exercise and main exercise in the rehabilitation room, whereas the control group were restricted. Result: As a result of constraint-induced movement therapy, affected side elbow joint flexion range, side shoulder joint extension range and side shoulder joint of the flexion range of motions increased obviously in the experimental group compared to those in the control group. Conclusion: The result above clearly shows that constraint-induced movement therapy is an effective intervention for the rehabilitation of hemiplegia patients in increasing affected side elbow joint of the flexion range of motion, the shoulder joint extension, and the increase of flexion range of motion.

Objective: The purpose of this study was to investigate the effect of the hip joint strengthening exercises using proprioceptive neuromuscular facilitation (PNF) on the clinical symptoms and the treatment effects in balance, sit to stand, and gait abilities in patients with TBI. Design: A single case study. Methods: A 13-year-old adolescent with quadriplegia and hip joint control impairment participated in this four-week training intervention. The patient, diagnosed with TBI, wastreated with hip joint strengthening exercises using PNF. In the first week, we focused on strengthening the body, relaxing the hip flexors and activating the hip extensor muscles in order to solve the patient's physical function and body structure. From the 2nd and 4th week, we improved the motivation through the task-oriented method, and then weight-bearing training of the right lower extremity was proceeded by kicking a soccor ball with the left lower extremity. The exercises were performed for 4 weeks, 5 days a week, for 60 minutes with the exercise intensity gradually increased according to the subject's physical abilities. Results: As a result of the study, the patient demonstrated improvements in the physical examination, which were evaluated before and after intervention and included the manual muscle test, modified Ashworth scale, sensory assessment, coordination assessment, Berg balance scale, 5-time sit to stand test, and the 10 meters walk test. Conclusions: The results of this case suggest that a hip joint strengthening exercise program using PNF may improve hip control ability, balance, sit to stand and gait ability in a patient with TBI.
