Objectives : This study is to dental knowledge and awareness of special education teachers. Methods : This study is conducted with a total of 244 special education teachers in Dae Gu, Gyeong Buk, Gyeong Nam, Bu San city from 1st April to 30th April, 2011. Results : More healthy state of oral health reflected higher point of oral health behavior. In the correlation among the oral health knowledge, behavior and education, higher oral health knowledge reflected higher oral health behavior. In the obstacle factors against oral health education, 41.0% was in the lack of professionalism and understanding of oral health education. The majority method for oral health education was regular teaching and the oral health in charge of education was school nurse 67.1%. The most important point for improvement for oral health class enabled was oral health recognition of teachers about the importance of education. Conclusions : For improving the oral health of the disabled, it is needed to develop the educational program or awareness of oral health monitoring like applying fluorine by special education teachers and parents, including the necessity of various oral health education development suitable for the special education school to make awareness in the importance and necessity of oral health.

Purpose: This study investigated the effects of simulation-based nursing education (for the care of congestive heart failure patients) on self-directed learning competency, clinical knowledge and problem-solving ability among nursing students. Methods: A one-group, pre-post design was utilized with 87 nursing students as the subjects. The scenario of simulation-based nursing education was created using a high-fidelity patient stimulator, and consisted of four states ((1) assessment, (2) reviewing laboratory data and administering medications and treatments, (3) managing increased dyspnea and decreased urine output, and (4) handling the "getting better" state). The simulation-based nursing education included orientation, team-based learning, team-based practice, and debriefing. The data were analyzed using descriptive statistics, Pearson's correlation coefficients and paired t-tests. Results: The scores on the factors for self-directed learning competency (t=-2.57, p= .011), clinical knowledge (t=-6.85, p<.001), and problem-solving ability (t=-3.01, p= .003) increased significantly after the education intervention. Conclusion: Simulation-based nursing education is useful in improving self-directed learning competency, clinical knowledge, and problem-solving ability in nursing students.

Purpose: This study was to identify knowledge, attitude, use and state of the Patient Controlled Analgesics (PCA) in postoperative patients. Method: The research design was a descriptive research. From December 7, 2005 to January 6, 2006, 102 postoperative patients in a university hospital at Daegu were participated in the study Results: Analgesics with PCA were mainly morphine complex 73.5% and Demerol complex 26.5%. Previous experience of using PCA was only 28.4%, and the main sources of information were other post-op patients and families(43.1%). The most common reason of choice was a recommendation from other post-op patients and families(46.1%). The most common side effects of PCA were nausea and vomiting(20.6%). About 57% of the patients were satisfied with PCA, and pain scores decreased with PCA. Mean score for knowledge about PCA was 2.55 out of a possible 6, and for attitude related to pain medication. 2.31 out of possible 5. Conclusion: To increase the score on knowledge of PCA, a structured preoperative PCA education program should be developed by nursing staff.

The article determines that the study of the development of scientific and didactic knowledge about the educational process in higher education should be built mainly on the basis of qualitative research methods that ensure the identification and understanding of the changes taking place in didactic knowledge, in the unity of their internal and external manifestations. On the basis of the epistemological model of the study of science, a generalized model of didactic knowledge about the educational process in higher education, including didactic relations as a theoretical core, subject of research, research methods and positions of researchers, ways of interaction between science and educational practice, and thematic structures of didactic knowledge; scientific and methodological problems of didactic knowledge about the educational process in higher education at the present stage of its developments due to the post-nonclassical transformation and orientation of research towards the humanitarian ideal of scientific character.

The conditions to be satisfied with SOC(State-of-Charge) indicator installed on the electric vehicle were that it should be used under frequent loading conditions and that it should enable the monitor to adjust to the aging effect. But, the state-of-charge test requires a lengthy stabilization period after discharge cycles and the ampere-hour test requires the knowledge of the battery capacity in terms of amp-hours. However, a monitoring technique combining the state-of-charge test to enable the monitor to adjust to the aging effect with the ampere-hour test to use under frequent loading condition is studied and implemented on a microcontroller-based circuit in this paper. Specially, optical fiber is used to realize hydrometer which is immune to electromagnetic interference and toxic environment and makes it possible to be used in a wide temperature range.

The fuzzy and state-feedback control systems have been applied in various areas from non-linear to linear systems. A Fuzzy controller is endowed with control rules and membership function that are constructed on the knowledge of expert, as like intuition and experience. but It is very difficult to obtain the exact values which are the membership function and consequent parameters. though apply back-propagation algorithm to the system, the convergence time a much. Besides, the state-feedback system is most widely used in industry due to its simple control structure and easily able to design the controller. but it is weak in complex system of higher degree and non-linear. In this paper presents the design of a fuzzy switching mode, it these two controllers work at different operation conditions, the advantages of both controller can be retained and the disadvantages can be removed. Between the Fuzzy and the State-feedback controlles, the good outputs are selected by the switching mode. Moreover it is powerful in complex system of higher degree and non-linear. In these sense compared with the state-feedback controller, the performance of the proposed controller was improvedin the section of linearization.

It is shown in this paper that it is possible to derive generalized state equations for computation of electrical circults constanining SCR and diode elements. Revankar's binary logic variable method is used for formulation of the state equation of chopper circuit. Advantage of this method is that the state equations can be set up without the exact knowledge of the circuit operaton. The different modes of operation of the circuit are identified by the computer itself. By applying this method, the steady state performances of separately excited chopper-fed dc motor considering the counter electromotive force of the motor are investigated and the results of the computer simulation are presented. There is a satisfactory agreement between the theoretical and experimental results.

To have more insight into the nature of plant, plant scientists carry out phytosociological studies on such plant species. The phytosociological studies on Tridax procumbens. Linn was carried out at Imo State University, Owerri, Imo State between the months of July and September, 2018. Tridax procumbens Linn grows abundantly in the areas under tropical climate and supported by a sandy-loam soil. Morphological features showed a range of variations. Phytosociological investigation showed a Tridax- Mitracarpus-Digitaria plant community. Tridax procumbens was positively associated with Digitaria horizontalis, Mitracarpus scarber and Vernonia cinera. The Inter-relationship of T. Procumbens was thus determined. This study therefore is a contribution to the general ecology of the plant. Phytosociological studies helps plant scientist to have more knowledge into the nature of plant species. This study is a contribution to the general ecology of the plant Tridax procumbens. The study also shows that it has close association with mitracarpus Scarber and Digitaria horizontalis. More work should be carried out to find out if these plant species flower and produce seeds at the same time or not.
