The purpose of this study is to find out the effects of taping therapy on muscle activities between the group of taping therapy treatment and control group before or after exercises. The subjects are 18 S college's healthy male students who do not have any problems in the legs and could bend the knee joint normally. Considering physique, condition of health and capacity for locomotion, 3 groups of each 6 persons for the experimentation were classified. Three groups composed of control group without taping therapy treatment for control group, group I with taping therapy treatment only before the experimentation and group II with taping therapy treatment during 24 hour. before and after the experimentation. EMG MP150 was used to evaluate the parameter of the lower leg's muscle activities the exercise before 5 min. after 10 min. and after 24 hour. for the experimentation. Compared with control group, group I and group II had more increased muscle activities in vastus lateralis and rectus femoris and was statistically significant. And group I and group II also had more increase in muscle activities than control group in vastus medialis, although there was no statistically significant. We found that taping therapy increased muscle activity positively. The application of taping therapy could be used not only for preventive effects for sports man but also therapeutic effects for general people.

Objectives: The objective of the study was to infection control by analyzing the influence of working environment on infection control activities in the dental hygienists. Methods: The cross-sectional study was based on a survey on a total of 377 dental hygienists working in dental settings. Multiple linear regression analysis was performed to examine the relationship of general characteristics and infection control activities. All statistical analyses were performed using the SPSS for Windows version 20.0, and p<0.05 was considered to be significant. Results: Predictive powers(=Adjusted $R^2$ of the investigated factors such as operation room, sterilization disinfection laundry, dental unit waterline, staff individual, infection control system, personal protective equipment, medical waste, hand hygiene, oral surgical procedures, clinical contact surfaces were adjusted $R^2=0.394$, 0.306, 0.277, 0.244, 0.241, 0.177, 0.165,, 0.154, 0.134, 0.124 respectively. Conclusions: In order to enhance infection control activities, the program development and implementation for the aseptic procedure is very important. The program should include periodic reinforcement of infection control education and regular monitoring of infection control activities.
Effects of raw soy flour(RSY) and black(RSB) feeding on protein concentration of liver and serum, and GOT, GPT and alkaline phosphatase activities of serum in diabetic and nondiabetic rats were studied. Male rats(Sprague-Dawley), mean weight of (338.4$\pm$19.2g) were assigned to six dietary groups and fed with the assigned diet for 28 days. For each experimental, some rats were injected with streptozotocin intraperitoneally(L.P.) to induce diabets, and other rats were injected with buffer L.P. as a control group. The liver, kidney and spleen weights relative to bo요 weigth were higher in raw yellow soy flour diet diabetes(D-RSY) and black soy flour diet diabetes(D-RSB) groups than control, but the body weights were lower than control. The protein and albumin concentrations of liver and serum were lower in D-RSY and D-RSB groups than control. The albumin concentration of serum in D-RSB group was lower than control. The GOT activities of serum in RSY and RSB groups were increased compared with control, but the GPT activities were lower in diabetic control, D-RSY and D-RSB groups than control. The alkaline phosphatase activities of serum in RSY and RSB groups were higher than control, but those in D-RSY and D-RSB groups were lower than diabetic control.
A shop floor control system(SFCS) performs the production activities required to fill orders. In order to effectively control these activities, the autonomous agent-based heterarchical shop floor control architecture is adopted where a supervisor does not exist. In this paper, we define functional perspective of the heterarchical shop floor control using planning, scheduling, and execution modules. In particular, we focus on an execution module that can coordinate the planning and scheduling modules and a general execution module that easily can be modified to execute the other equipment. The execution module can be defined informally as a module that downloads and performs a set of scheduled tasks. The execution module is also responsible for identifying and resolving various errors whether they come from hardware or software. The purpose of this research is to identify all the execution activities and solving techniques under the assumptions of the heterarchical control architecture. And we model the execution module in object-oriented modelling technique for generalization. The execution module modeled in object-oriented concept can be adopted to the other execution module easily. This paper also proposes a classification scheme for execution activities of the heterarchical control architecture. Petri-nets are used as a unified framework for modeling and controlling execution activities. For solving the nonexistence of a supervisor, a negotiation-based solution technique is utilized.
To evaluate the role of xanthine oxidase in liver damage by CCl4, a group of rats were fed tungstate for a month, which suppressed the activities of xanthine oxidase in serum and liver. Control group of rats were fed standard diet without tungstate. Liver damage was induced both in tungstate fed and control groups by two intraperitoneal injections of CCl4 at the level of 0.1ml/100g body weight at intervals of 24 hours. Increases in the levels of serum alanine aminotransferase by CCl4 were significantly smaller in tungstate fed rats than in control rats. Concomitantly, histopathologic changes were less in tungstate fed rats than in control ones. In rats either treated with CCl4 or not, hepatic type O xanthine oxidase activities were remarkably reduced by tungstate feeding. Hepatic aniline hydroxylase activities were higher in rats fed tungstate than control rats when animals were not treated with CCl4, but the enzyme activities were lower in tungstate fed rats than control when they were treated with CCl4. Neither tungstate feeding nor CCl4 treatment caused any significant changes in hepatic glutathione contents, and activities of hepatic glutathione S-transferase, glutathione peroxidase and superoxide dismutase. It is concluded xanthine oxidase reaction augment CCl4 induced liver damage via oxygen free radical system.
To evaluate the effects of Dexamethasone(Dex), Platelet derived growth factor-BB(PDGF) and combination of Dex and PDGF(DP) on the growth and differentiation of MC3T3-E1 cells, Dex($10^{-7}\;M$) and PDGF(10 ng/ml) in experimental group were added to the cells at the days 5, 10, 15, 20, 25 and examined for cell proliferation activities, DNA synthesis activities, ALP activities and bone nodule formation. The results were as follows : 1. In Dex group, cell proliferation, DNA synthesis and ALP activities were lower until 15 days when compared to the control group. Bone nodules formation were shown at 10 days. 2. In PDGF group, cell proliferation and DNA synthesis activities were higher until 15 days and ALP activities were lower when compared to the control and Dex groups. Bone nodules formation were shown at 20 days. 3. In DP group, cell proliferation and DNA synthesis activities of PDGF were suppressed by Dex and synergistic effects of combination of Dex and PDGF on ALP activities were shown at days 5 when compared to control and Dex groups. Bone nodules formation activities of Dex were suppressed by PDGF.
This study attempted to compare the social interest, motivation, and attitude of nursing college students who participated in a voluntary program and the students who didn't participate in a voluntary program. The purpose of this study can be summarized as to find the effect of a voluntary program and to offer fundamental data for institutionalizing a voluntary program in college. The subjects were composed of two groups, one group attend the voluntary program and the other group doesn't. The subjects were 390 nursing students: 179 in the experimental group and 211 in the control group. The results of this study are as follows : 1. Before voluntary activities, the mean value of the control group was higher than that of the experimental group in social interest and altruistic motivation. The difference is statistically meaningful(t= -2.2.53, p=.25, t= -2.509, p= .013). 2. After voluntary activities, selfish motivation and altruistic motivation in the experimental group was higher than before. The difference is statistically meaningful(t= 2.404, p=.0l7, t=-2.751, p=.007). 3. The social interest, selfish motivation, altruistic motivation toward voluntary activities and selfish attitude, altruistic attitude toward voluntary activities will not have changed in the control group before or after voluntary program. However, the altruistic attitude lowered after voluntary activity. It is statistically meaningful(t=2.694, p=.008). 4. After the voluntary activities, there was a significant difference between the experimental and control groups in altruistic attitude. In the experimental group, the mean value of altruistic attitude increased significantly, but in the control group the mean value of altruistic attitude decreased ( t = 2.15, p = .032). The results of this study showed that voluntary activities not only increase social interest and altruistic attitude, but also the subject's understanding toward the community. 3. The social interest, selfish motivation, altruistic motivation toward voluntary activities and selfish attitude, altruistic attitude toward voluntary activities will not have changed in the control group before or after voluntary program.

The effects of coping on physical and psychosocial adaptation in the 297 patients with rheumatoid arthritis were investigated. The coping methods were divided into compliance of medical regimens, self-control activities, and cognitive control. The effects of these coping methods was analyzed with stepwise regression. The physical adaptation is found to be significantly affected by cognitive control, self-control activities, and compliance of medical regimens in order Compliance of the medical regimens affects negatively the physical adaptation. And psychosocial adaptation is significantly affected by the cognitive control. The analysis of these results by illness duration showed the distinct differences. That is in the patients who experienced the disease less than 48 months, the physical and the psychosocial adaptation were significantly affected only by the cognitive control. But in the patients who experienced the disease more than 96 months, the physical and the psychosocial adaptation were significantly affected by self-control activities. Based upon these results, it is recommended that the nurses who care the newly diagnosed patients emphasize on the positive side of the state. And the patients who are diagnosed long ago need the nursing programs which teach and promote self-control activities. Also it is suggested that the results of compliance must be considered rather than as the result variable.
The ultimate aim of periodontal treatment is periodontal regeneration, which necessiates the regeneration of bone tissues. To evaluate the effects of Dex growth and differentiation of MC3T3-E1 cells, cells were seeded in alpha-modified eagle medium containing 10% fetal bovine serum, 10mM beta-glycerophosphate , $50{\mu}g/ml$ of ascorbic acid, with or without $10^{-7}M$ Dex and examined cell proliferation activities, alkaline phosphatase activities, and bone nodule formation until 25days. The results were as follows : 1. In Dex group, cell proliferation activities were lower until 15 days compared to control group. Bone nodules formation were showed at 10 days. 2. In the time-response effect, ALP activities were increased until the 10 days in control groups thereafter decreased and ALP activities of Dex group were lower aspect than control group until the 10 days In this study, bone nodule formation of osteoblast-like cells were accelerated by Dex and cell proliferation activities, ALP activity of Dex group showed lower than control group. Dex was considered that it did suppress initial growth, but accerelate mineralization of osteoblast-like cells.
