Emergent computing paradigms such as genetic algorithms have found increased use in problems in engineering design. These computational tools have been shown to be applicable in the solution of generically difficult design optimization problems characterized by nonconvexities in the design space and the presence of discrete and integer design variables. Another aspect of these computational paradigms that have been lumped under the bread subject category of soft computing, is the domain of artificial intelligence, knowledge-based expert system, and machine learning. The paper explores a machine learning paradigm referred to as teaming classifier systems to construct the high-quality global function approximations between the design variables and a response function for subsequent use in design optimization. A classifier system is a machine teaming system which learns syntactically simple string rules, called classifiers for guiding the system's performance in an arbitrary environment. The capability of a learning classifier system facilitates the adaptive selection of the optimal number of training data according to the noise and multimodality in the design space of interest. The present study used the polynomial based response surface as global function approximation tools and showed its effectiveness in the improvement on the approximation performance.

A four dimensional quantitative structure activity relationship analysis was applied to a series of 50 flavonoid inhibitors of $p56^{lck}$ protein tyrosine kinase by the molecular comparative electron topological method. It was found that the -log (IC50) values of the compounds were highly dependent on the topology, size and electrostatic character of the substituents at seven positions of the flavonoid scaffold in this study. Depending on the negative or positive charge of the groups correctly embedded in these substituents, three-dimensional bio-structure to increase or decrease -log (IC50) values in the training set of 39 compounds was predicted. The test set of 11 compounds was used to evaluate the predictivity of the model. To generate 4D-QSAR model, the defined function groups and pharmacophore used as topological descriptors in the calculation of activity were of sufficient statistical quality ($R^2$ = 0.72 and $Q^2$ = 0.69). Ligand docking approach by using Dock 6.0. These compounds include many flavonoid analogs, They were docked onto human families of p56lck PTKs retrieved from the Protein Data Bank, 1lkl.pdb.

The purpose of this study is to examine the effects of peer tutoring on students' achievement and learning satisfaction in a liberal computer class at university level. Traditional teaching method was applied for the control group consisting 55 students for 8 weeks. The experimental group containing 44 students was instructed using both traditional teaching method and peer tutoring. According to the results of diagnosed test, the experimental group was divided into heterogeneous ability group of 3 or 4. The tutor training was provided a week in advance of the class and the students played a role of a tutor and tutee by taking turns. The results showed no significant differences between the two groups on academic achievement; however, in terms of students' learning satisfaction, it displayed a wider range of results. The learning satisfaction data from the experimental group showed a much higher level than that of the control group. It is predicted that the amount of class hours of a week, the quality of the lecture and the application of peer tutoring affect the students' academic achievement. It is suggested that subsequent research on peer tutoring will allow for more in-depth study in this field.

Landing gear force reaction module is important for aircraft take off and landing simulation. But usually this modulo is not accounted for control law design simulation. because it does not affect the flying quality of aircraft. Now a days, this module is getting more important according to the increase of needs for training purpose simulation and specific control law design such as unmaned aircraft landing on the moving platform. In this paper 1DOF mass spring simple force system per gear was accepted.

Background: South Korea is rapidly being an aging-society and the demand of long-term care insurance services for elderly patients is rising. In addition, because the elderly taking multiple medicines, the adherence is lowered and the adverse events are easily occurred. Therefore, many are interested in introducing the geriatric pharmacy specialist to manage this situation. Purpose: By applying a similar program such as the geriatric pharmacy specialist working in nursing home, we conducted this study to evaluate the potential contribution to both the health insurance services and financial savings for the elderly patients. Methods: We conducted a trial in an elderly nursing home to collaborate between doctor and pharmacist making a checklist for improving medication adherence and establish a consultation system. Also we applied a smart phone application in the pharmaceutical care processes. Results: Thereby completing the drug therapy related checklist apply to nursing facilities in South Korea. And we got a performance that improves medication adherence when used in the clinical practice settings. Conclusion: By introducing a training program of pharmacy care managers and geriatric professionals such as the United States and Japan, we revealed the elderly nursing home residents and vulnerable elderly people living alone were improved the medication adherence and it will contributed to the health and quality of life of the patients.

Purpose: To improve self-management in elderly people with hypertension, the researcher examined the effects of an abdominal relaxed breathing exercises using biofeedback on blood pressure. These exercises regulate physical response to stress and lessen the activity of sympathetic nerves. Method: A single-experimental pre-and post-test design was used. Eight elderly people with hypertension participated in the study from April, 6 to June, 14, 2000. Biofeedback was done with soft ware by developed by J & J Company (1-410 form for abdominal respiration training). The abdominal relaxed breathing exercises are based on Mason's suggestion (1985) and were modified by Yu & Song(2001). This program consisted of 4 sessions once a week for four weeks. Data were analysed using SPSSPC+(10.0). Result: There was a significant decrease in systolic and diastolic blood pressure over three different times. There was a significant difference in the level of total stress response, overall health and quality of life but no significant difference in the level of emotional condition over three different times. Conclusion: The results of this study will contribute to the development of nursing strategies for the regulation of blood pressure in older people as the exercises are easy to learn and are a nonpharmacologic approach.

This qualitative research describes unique features of seven exemplary science teachers' professional development activities. Description of excellence in effective teachers' professional development efforts will provide some insights into required inservice initiatives and support systems for teachers' professional learning. Exemplary science teachers' professional development activities can be classified into four types: (1) practicing classroom supervision, (2) participating in voluntary communities of teachers, (3) playing instructional leader roles in teacher training programs, and (4) continuing one's studies at a graduate school. One of the common features of these exemplary teachers was that they can both articulate what makes teachers professionals and practice in accordance with their perspectives. These exemplary teachers not only improved their own classroom practices, but also participated actively in various professional communities to share their practical knowledge with their colleagues. The teachers have formed special-interest groups to investigate better ways of science teaching. They also took an active role in teachers' in-service education. Teachers' quality practices lie at the heart of classroom change. However, it's important to remember that there must be a support system that sustains and encourages teachers' initiatives. The implications for the support system to encourage teachers' professional development efforts are discussed.
