  • Purpose: This study was conducted in order to present basic policy data for introduction of a home-based physical therapy (HBPT) policy. Methods: The study surveyed physical therapists and patients for six weeks, in order to identify satisfaction with physical therapy. The statistical significance of the management plan with regard to costs and cost estimation and payment methods was determined and managed according to the operating principals of HBPT, eligibility criteria, number of visits, treatment time, and team approach. Results: Through the survey all groups of patients and physical therapists recognized the need for HBPT. They felt that the most desirable methods for activation of physical therapy visits involve precise diagnosis and evaluation through a team approach. While making regular visits to the patient three times a week, an expert visiting physical therapist with 3 to 5 years of experience in the clinical field could provide central nerve developmental treatment in less than 60 minutes; this service could be provided at a reasonable cost, minimizing unnecessary hospital visits, reducing time, medical expenses and facilitating a quick recovery due to psychological satisfaction resulting from a decrease in the psychological anxiety patients often experience in medical institutions. Conclusion: Based on the study results provided above, if HBPT is to be introduced, appropriate pricing and programs should be based on the results of pilot projects.

  • In this paper, the dyeing ability of the volcanic ash dyeing on cotton knitted fabrics were investigated. Acrylic copolymer was used to improve the depth of fabric color in the dyeing process. K/S values of dyed fabrics were measured to examine the dyeing properties. Two different classes of dyeing process were tested; (1) volcanic ash dyeing after pretreatment and (2) simultaneous co-treatment with volcanic ash and acrylic copolymer. In the first process, the effects of parameters such as the concentration of volcanic ash, concentration of Na2S04, dyeing time, dyeing temperature and pH of dyebath were noted. In the second process, the effects of parameters such as concentration of acrylic copolymer, dyeing time and temperature, and drying temperature were noted. Experimental results showed that the co-treatment of acrylic copolymer improved the dyeing properties of cotton knitted fabrics with volcanic ash. For the first dyeing experiment, concentration of dispersing agent was 0.1%, concentration of volcanic ash was 4%, treatment time was 20minutes, concentration of $Na_2SO_4$ was 2%, treatment temperature was $60^{\circ}C$ and treatment pH of dyebath was neutral. In the second dyeing experiment, concentration of acrylic copolymer was 2%, treatment temperature was $80^{\circ}C$, treatment time was 40 minutes, and treatment drying temperature was $150^{\circ}C$.

  • The purpose of this study was to determine the impact of situational, clinical and psychsoical factors on treatment-seeking behavior among those with acute myocardial infarction(AMI). This study used a retrospective, descriptive design. The sample consisted of 72 patients aged over 30 and who were diagnosed with an acute myocardial infarction at two large university-affiliated medical centers from July 1, 1998 to March 30, 2000. But of 72, patients 5 who were an outlier in treatment-seeking time were deleted. Data were collected by using questionnaires, which included demographic data, situational, clinical and psychosocial data. Also patient interviews and chart review were used to obtain information related to treatment-seeking time. The results of this study were summarized as follows ; 1. Mean time from the onset of AMI symptoms to arrival at the hospital was $12.09{\pm}11.44$ hours; 2. Treatment-seeking time was not significantly different by age, gender, or education; 3. Most(44 or 65.78%) patients were at home when they began having AMI symptoms. The remaining patients were either in a public area, workplace or in a car. Patients at home delayed longer than those who had their first symptoms elsewhere, but not significantly different. Also, most patients were with another person when they began to experience AMI symptoms: a spouse(25 or 37.3%), other family member(31 or 46.3%); the remaining 11 were alone. There were no significant differences in treatment-seeking time based on whether alone or with others. Most patients(46 or 68.7%) used an ambulance rather than taking private transportation, and patients who used an ambulance were delayed longer than those who used private transportation, but there were no significant differences; 4. Time to treatment-seeking was not significantly different by blood pressure, heart rate on admission and the peak CK-MB, CPK and Cholesterol level, Killips class; 5. There were no significant statistical differences in treament-seeking times by anxiety level, mood status or control ability.
