The purpose of this study was to investigate the related factor for the prevalence of musculoskeletal symptoms among 212 sewing worker. The survey was performed with self-administered questionnaire for the risk factors related to musculoskeletal disorders(MSDs) from August 5 to 7 in 2005. The prevalence of musculoskeletal symptoms were 75.8% and the those of the local symptoms were 71.7 % for shoulder, 60.4 % for neck, 35.8 % for arm and 50.9 % for wrist. The risk factors related the self-reported MSDs had not shown in general characteristics. But, there was a significant difference between daily working hour and wrist, working speed and neck, the degree of satisfaction and wrist for work related factor. Also, it was shown the significant difference between chair height and neck, the height of sewing machine and wrist among the space below work station, neck, waist for the prevalence of musculoskeletal symptoms. The significant correlation was shown for daily working hour and wrist, working speed and arm, work load and shoulder and the degree of satisfaction and arm for work related subjective symptom. Considering above results, it is suggested the ergonomic design be provided to working hour, the height of chair and work station as well as daily working hour even there is a significant difference for the prevalence of symptoms in each body part for sewing workers.
The recently revised Act on External Audit has taken effect as of November 2018, where standard audit hour rule is included to enhance the audit quality requiring appropriate audit hour input. It has two issues, one is how much the standard audit hours should be and the other is how to control the auditor proficiency between positions when deciding standard audit hours. This paper focuses on the latter issue and studies if auditor proficiency measured with the KICPA position proficiency weight is economically meaningful and has audit quality implication. The KICPA proficiency weights of partner and junior CPA are 1.2, and 0.4 with senior CPA being 1. The results are as follows. First, we find that the audit proficiency decreases discretionary accruals, the proxy of audit quality. Second, the degree to which the audit proficiency decreases discretionary accruals is pronounced with non-big4 firm. The results imply that the KICPA position proficiency weight reflects auditor experiences which help to improve audit quality.

Autopolymerized resin facilitates a more rapid and easier means for the construction of removable orthodontic appliances than heat cured resin. But many reports reveal that more unreacted monomer is found in autopolymerized resin. It is very important to achieve maximum degree of polymerization because if polymerization is inadequate, high level of unreacted monomer has been shown to adversely affect mechanical and physical properties, and also the question of allergy or toxicity to methylmethacrylate must be considered. The purpose of this study was to compare the degree of polymerization according to curing method and curing time. Five groups were desinged ; Group 1 was polymerizied at room temperature($28^{\circ}C$) ; Group 2 in $28^{\circ}C$ water ; Group 3 in $28^{\circ}C$ water under 30psi pressure ; Group 4 in $43^{\circ}C$ water ; Group 5 in $43^{\circ}C$ water under 30psi pressure for 10 minutes, 1 hour 12 hours, 1 day and 3 days. The degree of polymerization was measured by means of Fourier Transform Infrared spectroscopy. The results were as follows: 1. The degree of polymerization increased constantly in accordance with curing time in all groups and after curing for 10 minutes, Group 1 showed significantly higher degree of polymerization after 12 hours and Group 2, Group 3, Group 4, Group 5 after 1 hour(p<0.05). 2. The degree of polymerization decreased in the order of Group 5, Group 4, Group 3, Group 2, Group 1 except when the curing time was 1 hour and 12 hours(p<0.05). 3. The degree of polymerization of Group 4, Group 5 cured at $43^{\circ}C$ showed significantly higher degree of polymerization than Group 2, Group 3 at $28^{\circ}C$ except when the curing time was 1 day(p<0.05). 4. Among Group 2, Group 3 and Group 4, Group 5, the pressure had no effect on polymerization except when the curing time was 12 hours(p<0.05). 5. Between Group 1 and Group 2, the method of storage had no effect on polymerization except when the curing time was 1 hour(p<0.05).

Family and parents which serve as a primary group for the children's development also play important role in their cerebral palsy children's treatment. This study wants to know how the parents' participation in their children's physical therapy and satisfaction degree have an impact on their children's improvement of the motor function. For that purpose, a home made self filling survey was conducted of 156 cerebral palsy children's parents whose children were treated in 4 university general hospitals and 3 welfare centers from the 1st of April 2004 to the 31th of march 2005. The gross motor function was employed to evaluate the cerebral palsy children's motor function improvement. In this study, those questioned were divided into two groups according to the time of treatment. 'Group A' is consist of the patients whose parents attended to the treatment more than one hour at home. The patients who belonged to 'Group B' were treated less than one hour at home. The general features of the cerebral palsy children and their parents and the characteristics of their physical disability, the parents' participation and their satisfaction degree were examined by survey. Evaluating the difference between two groups' motor function according to their parents participation degree in the physical therapy leads to the following results. First, 'Group A' was better than 'Group B' in their satisfaction degree with the physical therapy and participation degree. Statistically 'Group A' was superior to 'Group B' in the requirements of the information and education for the children with cerebral palsy. Second, after two months of treatment, 'Group A' showed more statistically significant improvement than 'Group B' in every items as like lying in item 1, sitting in item2, crawling and kneeling in item 3, standing in item 4, walking,running, jumping in item 5. Third, parents' participation in physical therapy and satisfaction degree have some relevance to their children' motor function improvement. The satisfaction degree is related to motor function like crawling and kneeling in item 3, walking,running, jumping in item 5. It is showed that the parents' participation degree and information about handicapped children.
This paper introduces the method to develop two main types of the fuzzy OEE (Overall Equipment Effectiveness) models via triangular membership function for measuring uncertainty. The fuzzy OEE includes model type 1 and model type 2. The model type 1 is used when the theoretical machine speed only reflects the time loss whereas model type 2 is used when the actual machine speed reflects both time and speed loss. Model type 2 has shown to perform a lower availability rate and a higher performance rate compared to model type 1. In addition, the fuzzy UPH (Unit Per Hour) which is derived from using the fuzzy OEE is presented to satisfy demand uncertainty. The fuzzy UPH can easily measure the fuzzy tact time and cycle time by reciprocating itself. Finally, this study demonstrates the fuzzy OEE models using IVIFS (Interval-Valued Intuitionistic Fuzzy Set) based on the characterization via membership function, non-membership function and hesitant function. For the purpose of analyzing the fuzzy system OEE, the OEE for each machine of plant structure is considered triangular interval-valued intuitionistic fuzzy number. Regardless of plant structure, the validity degree of fuzzy membership function of system OEE decreases when the number of machine with worst value of the validity degree increases. Corresponding examples are presented in this paper for practitioner to understand the applicability and practicability of the proposed fuzzy OEE methods.
Purpose: The purpose of this study was to examine the effect of position change on the level of comfort and occurrence of bleeding after transarterial chemoembolization. Methods: This study was the nonequivalent control group non-synchronized design. The experimental group was positioned in supine with 15-30 degree Semi-folwer's position for 2 hours and then changed supine position alternatively to 30 degree lateral positioning in turn per hour for 2 hours. For the control group, 6 hour supine positions without any position change were applied. Results: The level of discomfort of the control group was scored higher level than that of the experimental group. There was no significant differences in back pain and the degrees of voiding difficulty. There were no significant differences in the incidence of bleeding complication between the two groups. Conclusion: The position change in patients after transarterial chemoembolization could be applied without any severe side effects such as bleeding complication, but it was revealed to be effective in reducing the level of discomfort.
This study was conducted in order to determine the effect of Paraffin Therapy on release of pain, skin temperature and range of motion with joint diseases. This study was performed on 42 patients with general joint diseases and 21 patients with degenerative joint diseases. All the subjects were randomly assigned to three groups with 21 each. The experiment had been done from June, 1. 2002 to September, 30. 2002, in two general hospitals and a social welfare center using Digital Thermometer Kane-May KM330 and VAS(visual analogue scale). Each pint was measured in terms of skin temperature, pain scale and ROM(range of motion). The results of the experiment are as follows : 1. In application of three different heat modalities (Paraffin bath, Infra red, Hydro pack) on the Knee, Ankle, Elbow pints of the subjects for 30 minutes, the elevation of skin temperature and the reduction of pain scale were found to be significantly different. When checked right after the 30 minutes' application, the Infra red resulted in a higher degree elevation of skin temperature than two other modalities, while Paraffin bath resulted in the highest degree of the elevation of skin temperature when it was checked one hour after the application was over. It means that Paraffin bath lasted longer than the other two modalities(F=14.691, p<.000). 2. With Paraffin bath application, pint pain was reduced significantly both in 30 minutes and one hour checks(F=20.675, p<.001). 3. In terms of ROM(range of motion) increase, didn't seem to have any significant differences in 30 minutes and one hour. The results suggest that Paraffin therapy be helpful in maximizing th effects on pint diseases. I strongly suggest that further studies be done on other pints and muscle diseases using Paraffin bath in different methods of applying the therapy.
Pseudocercospora leaf spot was major disease of grape cultivar 'Campbell Early' in Korea. Leaf spot first appeared in early June and rapidly dispersed to other leaves through rainy season. Disease progress of leaf spot by Pseudocercospora vitis in plastic green house, in the two provinces (Gimje and Gimcheon), were investigated in 2007. Differences of Infected leaves (%) between cultivation systems were observed in field and plastic green house, but there was no difference between provinces. Micro environmental factors, such as temperature and relative humidity, were correlated with infected leaves by PROC REG procedure of SAS (Statistical Analysis System). As a result, regression model best described ($R^2=0.95^{**}$) the infected leaves as a function of the interaction of cumulated temperatures; Y (Infected leaves)=-7.0101+0.0496$\times$20Hcum (Cumulated hour above 20 degree)+0.0208$\times$20cum (Cumulated temperature above 20 degree)-0.2781$\times$25Hcum (Cumulated hour above 25 degree). A statistics model was shown that cumulated hour and temperature above specific degree were critical factor for Pseudocercospora leaf spot on the grapevine leaves in plastic green house.
Occupational cumulative traumas (CTDs) are becoming one of leading ailments in industrialized worl $d^{(1.2)}$. The degree of muscle fatigue is important parameter to understand cause of occupational cumulative trauma disorders. To quantify degree of muscle fatigue, muscle EMG activity was measured during isometric and dynamic contractions(repetitive concentric/eccentric muscle contraction) and its analyzed data, such as RMS, median frequency, and median power were compared when the muscle was fresh and exhausted. When muscle become fatigue, it was observed that median frequency decreased and median power and RMS increased However, based on overall prolonged observation, median frequency increased and median power and RMS decreased. Therefore it was concluded that shifting patterns of RMS, median frequency, and median power values can be used as parameter to evaluate degree of muscle fatigue even in dynamic muscle contraction.
