The problem should be approached in terms of recovering essential functions of technical high school and identification to supply stable and quality human resources in technical sector. An adequate space programming for technical high school is needed to educate effective skills and techniques. Considering the education directions of vocational high school, the article covers principals of technical school's construction plan and directions and, based on this, suggest the way of estimating the scale in construction plan of technical school. Through this research, systematic and reasonable space planning can be possible. The range of this research is based on development directions of society and education and an objective standard in a newly reformed the 7th Stage of Education. In addition, the research is limited to technical high school among kinds of vocational high school. The purpose is to redefine the role of technical school that face identification crisis currently, comparing to the past, and to suggest a more effective space planning. The research limits the space to classes for specialized subjects, a core space for education in technical school among diverse spaces.

Purpose: This study aimed to determine the core competencies for 119 emergency medical technicians (EMTs) and to provide evidence for the development and utilization of 119 EMTs, education and training programs. Methods: Data were collected with a questionnaire that consisted of items on the general characteristics of the subjects (8 items) and importance and satisfaction levels for 10 competencies, including 34 items on subfactors. The Borich Needs Assessment Model was used in designing the questionnaire. A locus for focus model was used to derive the top priority competencies for the improvement of core competency in the profession. Data were analyzed with by SPSS ver.21 (IBM, Armonk, NY, USA). Results: The core competencies for 119 EMTs were derived from technical competency, information competency, communication competency, problem-solving competency, self-development competency and interpersonal competency. In addition, among the sub-factors of these competencies, 16 abilities (including leadership), ability to apply technical knowledge, technical comprehension, conflict management ability, ability to create documents, problem handling ability, ability to think, technical selection ability, and computer literacy were included in the priority category. Conclusion: This study derived and presented the core competencies for 119 EMTs to enable them to meet the modern day requirements of their roles, which may contribute to enhancing their professionalism.

Optimum cost design of columns subjected to axial force and uniaxial bending moment is presented in this paper. In the formulation of the optimum design problem, the height and width of the column, diameter and number of reinforcement bars are treated as design variables. The design constraints are implemented according to ACI 318-08 and studies in the literature. The objective function is taken as the cost of unit length of the column consisting the cost of concrete, steel, and shuttering. The solution of the design problem is obtained using the artificial bee colony algorithm which is one of the recent additions to metaheuristic techniques. The Artificial Bee Colony Algorithm is imitated the foraging behaviors of bee swarms. In application of this algorithm to the constraint problem, Deb's constraint handling method is used. Obtained results showed that the optimum value of numerical example is nearly same with the existing values in the literature.

It has been problematic to repulp the dry broke treated with permanent wet strength agents like PAE, UF and MF. Solution type GPAM has the benefit of easy repulping but it has problems of cocross-linking and tends to gel. Therefore, the product concentration must be lower than 10% to reduce the gel generation problem. We developed emulsion type GPAM by an inverse emulsion technology to resolve both the repulping problem with permanent wet strength agents and the stability problem of GPAM solution products.

In this paper, a receding contact problem for an elastic layer resting on two quarter planes is considered. The layer is pressed by a stamp and distributed loads. It is assumed that the contact surfaces are frictionless and only compressive traction can be transmitted through the contact surfaces. In addition the effect of body forces are neglected. Firstly, the problem is solved analytically based on theory of elasticity. In this solution, the problem is reduced into a system of singular integral equations in which contact areas and contact stresses are unknowns using boundary conditions and integral transform techniques. This system is solved numerically using Gauss-Jacobi integral formulation. Secondly, two dimensional finite element analysis of the problem is carried out using ANSYS. The dimensionless quantities for the contact areas and the contact pressures are calculated under various distributed load conditions using both solutions. It is concluded that the position and the magnitude of the distributed load have an important role on the contact area and contact pressure distribution between layer and quarter plane contact surface. The analytic results are verified by comparison with finite element results.

The Web based multimedia programmes/courses are becoming widely available in recent years. Most of these courses focus on Behaviorist way of learning, which does not promote deep learning in any way. For Adults this approach further incapacitated, as it does not satisfy Andragogical needs. The search for Constructivist way of learning through the web applied to Indian conditions led to need for developing a curriculum development approach that would promote construction of knowledge through web based collaboration. This paper attempts to reengineer existing curriculum development processes and lays out a framework of‘Problem Based Online Learning (PBOL)’curriculum design. In this context, entire curriculum development life cycle is evolved and explained. This is a part of doctoral work (Ph.D), which is in progress and being undertaken by K.James Mathai, and guided of Dr.D.S.Karaulia.

This study presents the results of a delphi survey which is intended to identify technical skills that corporations expect of employees. A total of 300 managers from different businesses took part in the survey. To obtain the delphi data, a questionnaire of expected technical skills developed on the basis of previous research was used. The obtained data were analyzed in terms of frequency and other descriptive statistics. Eleven technical skills emerged as important ones in the corporate environment. In order of importance, subjects listed communication skills, business capabilities, negotiation skills, problem-solving ability, organizational adaptation, ability to gather and analyze relevant information, practical computer literacy, self-management, creativity, and foreign language proficiency.

Vitamin C's function and mechanism are comparatively well known among the several kinds of vitamins. Inhibition of free radical. promotion of collagen synthesis, restraint of melanin formation and resolution of melanin are its main functions. But Vitamin C is very easy to oxidize by heat, moisture or air so it causes stability problem to make formulation. To solve these problems unique formulating method or derivatives using method could be effective. Object: First, stabilize 10% of Ascorbic acid as polyol/silicone emulsion and try to make polyol/silicone/polyol anhydrous multiple emulsion secondly. And then, encapsulate with porous power to enhance the stability of Ascorbic Acid from formulating method.

In recent, the demand of high-productivity injection mold is increased because of the growth of international packaging market which is induced by an increase of population. The increase of productivity leads to the large-capacity injection molding machine and peripheral devices. For solving this problem, the stack mold which is based on the exsiting machine and device has researched in advanced countries actively. In this paper, as the preliminary research of stack mold development, the stack mold which has 2 level ${\times}4$ cavity was designed and fabricated. Besides, the motion and structural analysis were performed to verify the stability of developed stack mold.
