  • Compression wear provides clothing pressure and affects how blood flows. Facilitating a blood flow is one of the most important functions of compression wear. The wearer's sensibility should be considered when designing compression wear. This study instructed participants to put on 5 types of sport compression wear with different pressure levels (CP-1 to CP-5), measured clothing pressure, blood flow level, blood flow rate, and surface temperature, and examined the pressure level that influenced blood flow through a subjective sensibility assessment. An experiment measured the clothing pressure of compression wear available in the market and found that the pressure ranged 0.6-1.1 kPa for the ankle, 0.7-2.3 kPa for the calf, and 0.9-1.9 kPa for the thigh. Meanwhile, blood flow levels and rates significantly increased when participants wore CP-1, which had the highest clothing pressure level, and CP-2 and CP-4 with middle-level pressure. After exercise, CP-2's surface temperature was the highest and revealed that wearing CP-2 facilitated blood flow. CP-2 was evaluated as most positive in the sensibility assessment and showed a clothing pressure of 0.67-1.82 kPa; its pressure for the calf did not surpass 2.0 kPa. Considering positive physical effect of compression wear on blood flow and subjective psychological effect on participants, CP-2 (0.67-1.82 kPa) would have the most suitable clothing pressure level among other types of the wear in this study.

  • This study is to verify how the economic, social and moderating effect factors of baby boomer generation workers' affect the subjective health evaluation. The subjective of this study was 1,202 workers of baby boomer generation by using the 4th data of Korea longitudinal study of aging(KLoSA) from Korea Labor Institute in 2012. Economic and social factors were selected as scales to analyze if there is meaningful difference in subjective health evaluation. Method of frequency analysis, t-test, ANOVA and correlation analysis was used, and multi regression analysis was also conducted to verify whether the private health insurance has control effect over the relation between the subjective health evaluation and the economic & social factor. As a result of the study, age, education, home ownership, peer group meeting, overall satisfaction, private health insurance were major factors affecting the subjective health evaluation of baby boomer generation. Moreover private health care were turned out to have a moderation effect in relation between economic, social factor and subjective health evaluation.

  • The purposes of this study were to research the current state of evaluation of children with delayed development and cerebral palsy and determine pediatric physical therapists' knowledge of assessment tools and their use. The subjects were 130 pediatric physical therapists (general hospitals, university-related hospitals, rehabilitation centers, etc.). Data was obtained from August 24, 1999 to October 18, 1999 by means of a survey questionnaire. The results were as follows: 1. The current state of pediatric physical therapist evaluation of children with delayed development and cerebral palsy. 1) Tools used to assess functional areas of children with cerebral palsy were: subjective description format-128 (47.1%); the GMFM-58 (21.3%); facility-generated tool-51 (18.8%); and DDST-15 (5.5%). 2) Tools used to assess developmentally delayed children were: subjective description format-121 (50.6%); the GMFM-43 (18.0%); facility-generated tool-41 (17.2%); and DDS T-14 (5.9%). 3) After their college or university study, therapists who had attended lectures on evaluation were 113 (86.9%); 13 (10.0%) therapists had not attended any lectures on evaluation 2. Test scores of physical therapists' professional knowledge of evaluation procedures: high (more than 36 points)-74 (56.9%); moderate (18~35 points)-39 (30.0%); and low (below 17 points)-none. 1) For therapists treating cerebral palsied children, 73 (65.2%) were in the high range, 39 (34.8%) were in the moderate range and none were in the low range. 2) For therapists treating children with delayed development, 71 (65.7%) were in the high range, 37 (34.3%) were in the moderate range and none were in the low range. Although the general degree of professional knowledge of evaluation was quite high, there was a lack of variety in the assessment tools used With a large number of therapists depending on subjective description. Possible reasons for the low rate of objective asses sment tool use: 1) Poor clinical environment: too many clients and lirnited treatment time. 2) Lack of any medical insurance fee category for specific assessment tools. 3) Lack of continuing education opportunities in pediatric evaluation skills during or after either college-based (3 year) or university-based (4 year) education programs. Based on the study results, provision of more extended educational opportunities would promote the use of a greater variety of objective assessment tools by pediatric physical therapists.

  • Objective: The purposes of this experiment are an analysis of accuracy between target force level and subjective rating for the Target Force Level and an analysis of the patterns of subjective rating depending on target force level when there is no feedback from males for analysis. Background: The study of perceived exertion about the static contraction is processed with using among the matching procedure method between contralateral limbs, Exertion vs. Borg CR-10 scale and Exertion vs. %MVC (Maximum Voluntary Contraction). However, when there is no feedback, there is lack of the study on whether the subject can distinguish the subjective rating of the force depending on the target force levels. Method: Total 30 males, healthy subjects are measured the maximum grip strength, MVC, and then, each subject is measured the subjective rating and the accuracy with the random target force level (10, 20, 30, 40, 50, 60, 70, 80, and 90% MVC). Results: In the MVC study, males exerted 256.87N (${\pm}51.33$). In the subjective rating of grip strength increased for each Target Force Level (9 levels), higher subjective rating evaluated (p<0.05). In accuracy examination between target force level and subjective rating of grip strength by each %MVC, 10, 30, 40, 50, 70, 90% target force levels showed accurate strength (p>0.05). However, at 20% target force level, the subjects evaluated less subjective rating of grip strength than the target force (Underestimation), and at 60% and 80% target force level, the subjects evaluated more subjective rating of grip strength than the target force (Overestimation) (p<0.05). Conclusion: In the experiment, the MVC showed 256.87N (${\pm}51.33$) for the male adults and as the subjective rating value increased for each Target Force Level (9 levels), higher subjective rating evaluated (p<0.05). Moreover, the results of the accuracy test between target forces and subjective rating of the subjects showed that most participants rated a fairly accurate assessment of subjective rating of grip strength for Target Force Level (9 levels), except for 20%, 60%, and 80%MVC. Application: This experimental result would be used for basic data for the subjective rating of grip strength pattern by the target force level when the voluntary muscle is contracted.

  • The technical proposal suggested and published by MIC(Ministry of Information and Communication, henceforth MIC) contains too general assessment elements, which causes qualitative and subjective assessment of technical proposals. Thus, in terms of the technical proposal assessment. It lacks In fairness, validity and accuracy. Furthermore, it has a great deal of difficulty in assessment caused by the inconsistency between proposal planning and assessment methods. Also, each company has different writing format, so it is impossible to make use of its maneuvering data for the assessment. To overcome these weaknesses, our research focused on a quantitative evaluation on development organization, which is a part of organizational and administrative part of the technical proposal suggested and published by MIC. In this research, we divided development organization for the technical proposal into organization, teams, and team members, and then studied addition, deletion and merging for the assessment criteria. For the related study, we chose especially CMM(Capability Maturity Model) from a lot of international and national references, which is a model measuring the maturity of organization, and then we focused on Small-CMM which is available in the small-sized organization. We also suggested input form, description method, assessment elements for the quantitative assessment in the chosen developmental organization, and finally we proposed standard referencing criteria for the assessment. Our study concludes that our assessment method are valid and available in comparison with the previous Delphi method through a validity evaluation test.

  • In the risk assessment of urban railway systems, a hazard log is created by identifying hazards from accident and failure data. Then, based on a risk matrix, evaluators analyze the frequency and severity of the occurrence of the hazards, conduct the risk assessment, and then establish safety measures for the risk factors prior to risk control. However, because subjective judgments based on the evaluators' experiences affect the risk assessment results, a more objective and automated risk assessment system must be established. In this study, we propose a risk assessment model in which an adaptive neuro-fuzzy inference system (ANFIS), which is combined in artificial neural networks (ANN) and fuzzy inference system (FIS), is applied to the risk assessment of urban railway systems. The newly proposed model is more objective and automated, alleviating the limitations of risk assessments that use a risk matrix. In addition, the reliability of the model was verified by comparing the risk assessment results and risk control priorities between the newly proposed ANFIS-based risk assessment model and the risk assessment using a risk matrix. Results of the comparison indicate that a high level of accuracy was demonstrated in the risk assessment results of the proposed model, and uncertainty and subjectivity were mitigated in the risk control priority.

  • The relationship of stress and psychopathology with subjective or objective tinnitus intensity was investigated in 43 patients with tinnitus. Global assessment of recent stress scale, Beck depression inventory and symptom checklist-90-revision were used to measure stress perception and psychopathology. Subjective tinnitus intensity was assessed by subjective tinnitus severity inventory, whereas objective tinnitus intensity was assessed by tinnitogram. Scores of perceived stress related to interpersonal relationship and sickness or min had significantly positive correlation with subjective tinnitus intensity. In psychopathology, scores of somatization, interpersonal sensitivity, depression, anxiety, phobia, paranoid ideation, psychoticism had significantly positive correlation with subjective tinnitus intensity. However, stress perception and psychopathology did not significantly correlate with objective tinnitus intensity. These findings suggest that tinnitus may be associated with stress perception and multiple psychopathology including anxiety and depression. Thus, it is emphasized that Psychosocial intervention as well as effective consultation-liasion activity is needed for evaluation and treatment of patients with tinnitus.

  • This thesis investigates 220 female students ranging from 19 to 26 years old attending universities in the Wonju area to determine the correlations between mental health and the density of serum iron . According to their serum iron levels, they were divided into three groups and analyzed with the GARS Scale Assessment and the THI Test Assessment. The results are as follows;1. On the comprehensive GARS Scale tests, for all groups, task, occupation and levels of university-related frustration(1) marked the highest scores.2. On the comparative assessment of each group's GARS Scale scores, Group A showed higher stress perception in terms of personal relationship(2,3) than any orther groups. 3. On the comprehensive THI test scores coverring all groups, Multiple subjective symptoms(I) marked the highest scores. 4. On the comparative assessment of each group's THI test scores, Group A showed higher Multiple subjective symptoms(I) and Irregularities of life(G) than any orther groups.5. Comparing and analyzing the GARS Scale Assessment and the THI Test, we found that Group A showed high stress perception, which may cause psychosomatic diseases such as 'yu zheng(鬱證;melancholia). With those results, we can see that the contant of serum iron is correlated to stress perception and the condition of mental health. In the future studies using the GARS Scale and the THI Test, it will be necessary to examine more subject groups in terms of multi-aspects and to investigate the standard group in more detail.

  • Writing is a subjective and performative activity. Writing ability has multi-facets and compoundness. To understand the examinees's writing ability accurately and provide effective writing scores, raters first ought to have the competency regarding assessment. Therefore, this study is significant as a fundamental research about rater's characteristics on the TOPIK writing assessment. 150 scripts of the 47th TOPIK examinees were selected randomly, and were further rated independently by 20 raters. The many-facet Rasch model was used to generate individualized feedback reports on each rater's relative severity and consistency with respect to particular categories of the rating scale. This study was analyzed using the FACETS ver 3.71.4 program. Overfit and misfit raters showed many difficulties for noticing the difference between assessment factors and interpreting the criteria. Writing raters appear to have much confusion when interpreting the assessment criteria, and especially, overfit and misfit teachers interpret the criteria arbitrarily. The main reason of overfit and misfit is the confusion about assessment factors and criteria in finding basis for scoring. Therefore, there needs to be more training and research is needed for raters based on this type of writing assessment characteristics. This study is recognized significantly in that it collectively examined writing assessment characteristics of writing raters, and visually confirmed the assessment error aspects of writing assessment.
