  • A series of experiments were conducted on dental denture base resins for their antibiosis. They were also compared in terms of physical and mechanical characteristics, which led to the following results: 1. As for bacterial deposition, the old products showed a wide range of distribution, while those products containing C. S. had restraints. 2. Among the products containing C. S., those ones of 7, 12 and 20% all had restraints of similar size to slop further bacterial growth. In the meanwhile, the old products had only small-size restraints for bacterial growth. 3. The following changes were observed in the aspect physical characteristics: There were no significance between the old products and the C. S. products. Thus, as for compressive force, the average${\pm}$standard deviation of the old products was $27.4083.{\pm}1.7397$, and those C. S. products of 20% showed the similar $27.5600{\pm}.1976$. In addition, there were no significance between the old products and those ones containing C. S. in terms of tensile force. The tensile force of the old products was $114.5600{\pm}.8916$ in average${\pm}$standard deviation, while there was no differences among the C. S. products of 7, 12, and 20% in that matter.

  • The architectural, facility makes the housing environment more pleasant, while too much noise coming from machinery room is detrimental to the workers physically and mentally. Therefore, more sound insulation and sound proof policies are increasingly required. However, as the annoyance caused by facility noise is influenced by various human listening characteristics as well as physical characteristics such as sound pressure level, it requires subjective evaluation characteristics through acoustic-psychological approach. For this purpose, the facility noise in the machinery room was actually measured and analyzed in the field to understand physical characteristics, and the correlation between physical evaluation value and psychological response value through listening test. Further, this study aims at presenting the data to set the standards of 'Just noticeable difference' of the facility noise together with reasonable evaluation with psychological reaction, through the grading of facility noise using trend formula. In the result, 13 stages of physical properties were forecasted for each evaluation method, together with 'Just noticeable difference' using the grading of architectural facility noise.

  • Objective: The purpose of this study was to investigate the effects of 5 different personalities on job stress in physical therapists. Design: Descriptive cross-sectional study. Methods: Structured self-report questionnaires consisted of demographic items, 5 types of personalities, and occupational stress. A questionnaire was distributed to 420 physical therapists working in Seoul and Incheon who had voluntarily agreed to participate in the study after the purpose of the study was explained. Of the 420 questionnaires, 405 questionnaires were collected and showed a recovery rate of 96.4%, of which 28 cases were excluded, leaving a total of 377 questionnaires being used for analyses. Pearson correlation analysis was performed to investigate the correlation of job stress and five personalities types. In addition, multiple regression analysis was performed to investigate the effect of general and occupational characteristics of physical therapist on job stress and the effect of personality type on occupational stress. All statistical significance levels were set at p<0.05. Results: The highest number of subjects, which were the physical therapists, showed the tendency to have a sincere personality, followed by affinity, openness, extroversion, and neuroticism. Physical therapists reported to be the most stressed in the order of professional role conflict, overload of work, work relation with a physician and supervisor, interpersonal relationship with patient and caregiver. The higher the level of affinity and sincerity, the lower the amount of stress received by the therapist from the interpersonal relationships between the patient and caregivers. On the other hand, the greater the level of openness and sincerity, the lower the stress levels related to professional role conflict. Conclusions: This study showed that the personality type and job stress of physiotherapists had a statistically significant effect. It is very important for physiotherapists to find their own way of coping with stress, which is satisfactory and appropriate for their job, because it is related not only to individual problems but also to the quality of patient care and medical services. Therefore, it is necessary to continue conducting research on how to relieve the stress levels of physical therapists according to their personality characteristics.

  • The purpose of the research was to examine the effect of three different levels of enzyme treatment on the physical characteristics and the end-use suitability of the lyocell fabrics made with four different types of commercial wood pulp. The appropriate enzyme concentration for obtaining an optimum as well as consistent physical characteristics and fabric hand trait was 3 g/l for the concentration levels tested in the present investigation. Weight loss was more affected by higher enzyme con­centration than other physical properties. H2 was least affected by enzyme treatment for all three physical properties and fab­ric hand. 5 g/l concentration exhibited little difference from 3 g/l in the physical characteristics, whereas the KES-FB values indicated a significant loss of fabric hand in most PHV s with the 5 g/l concentration level. Among different garment parame­ters, all four fabric types were relatively inappropriate for the men's slacks (MS) fabric due to the lower hand value of koshi required by the MS parameter. However, despite the relatively low koshi values, high fukurami values required for men's dress shirt (MWDS) resulted in the highest THV among the four garment parmeters. The four fabric types, which represent the usage of four different wood pulps, in general seem to exhibit a higher applicability to women's winter thin dress (WWTD) than women's winter suit (WWS) garment parameter.
