The purpose this study is to analyze how human resources in culture and arts education use the contents of Arts Academy training program in the field, and to suggest implications and improvements of the training for strengthening the competence of professional manpower. For this purpose, an online survey was conducted for the participants of the Arte Academy training program to investigate the actual application rate. As a result of the analysis, overall application of the training was high. However, the work-site application was divided into indirect and direct applications. Indirect application showed higher results than direct application. This shows that the training is effective in terms of strengthening the participants' personal competence, but they are somewhat lacking in applying the contents learned in the training directly in the field. Indirect application is a result of training and is a necessary part of strengthening competence. However, considering that culture and arts education is a consumer-oriented policy that enjoys culture and art, it needs to be strengthened more directly in the field, and the competence of the applicant should be applied to the field more smoothly. The Korea Arts & Culture Education Service needs to review and implement such a training that has a higher direct application than indirect application.

The purposel of this study was to examine the effects which the direct and the indirect instructions at a Home Economics class have on improving the learning achievements and attitudes. To accomplish these goals. 90 students. the number of two classes of the first tirade at p high school at Anyang city of Kyonggi province were selected. They are composed of the experimental group and the comparative group. Each group contained 40 students. The former was implemented by indirect instructions and the latter direct instructions. The 'Family and Domestic Life' unit of the first tirade was selected as the study subject to take effects and 30 periods of class were enforced. For the experimental measure of this study. the researcher used a pre-learning test. a learning attitude test. and a learning achievement test as means of measure. The two groups were confirmed as the group having the same quality, So after the experimental measure, the results of the post tests(included a learning achievement test and a learning attitude test) were verified by T-test in order to research the problematic subject. and SPSS/win statistics package was used for the processing of the statistics. The results are following: 1. The direct and the indirect instructions represented the meaningful differences in the learning achievements (p <.05). They represented the meaningful differences in improving the learning achievements of knowledge and understanding(p <.05). It was verified that the (order is more effective than the latter in improving the learning achievements of knowledge and understanding, and They represented the meaningful differences in the improving learning achievements of application (p <.05) 2. They represented the meaningful differences in the learning attitudes at a domestic class(p <.05) The latter is more effective than the former in changing into the positive learning attitudes. In the light of these result7. the direct instructions are effective in improving the learning achievements of knowledge and understanding. and the indirect instructions are effective in improving the learning achievements of application. Also the indirect instructions are more effective than the direct instructions in changing into the positive learning attitude.

For mass production of electronic devices, the processing of the printing roll is one of the most important key technologies for printed electronics technology. A roll of printing process, the gravure printing that is used to print the electronic device is most often used. The indirect laser processing has been used in order to produce printing roll for gravure printing. It consists of the following processing that is coating of photo polymer or black lacquer on the surface of printing roll, pattering using a laser beam and etching process. In this study, we have carried out study on the coating and etching for $25{\mu}m$ line width on the printing roll. To do this goals, a $4{\mu}m$ coating thickness and 20% average coating thickness of the coating homogeneity of variance is performed. The factors to determine the thickness and homogeneity are a viscosity of coating solution, the liquid injection, the number of injection, feed rate, rotational speed, and the like. After the laser patterning, a line width of $25{\mu}m$ or less was confirmed to be processed through etching and the chromium plating process.

The new field of learning control develops controllers that learn to improve their performance at executing a given task, based on experience performin this specific task. In a previous work［6］, the authors presented a theory of indirect learning control based on use of indirect adaptive control concepts employing simultaneous identification ad control. This paper develops improved indirect learning control algorithms, and studies the use of such controllers in decentralized systems. The original motivation of the learning control field was learning in robots doing repetitive tasks such as on an assembly line. This paper starts with decentralized discrete time systems, and progresses to the robot application, modeling the robot as a time varying linear system in the neighborhood of the nominal trajectory, and using the usual robot controllers that are decentralized, treating each link as if it is independent of any coupling with other links. The basic result of the paper is to show that stability of the indirect learning controllers for all subsystems when the coupling between subsystems is turned off, assures convergence to zero tracking error of the decentralized indirect learning control of the coupled system, provided that the sample time in the digital learning controller is sufficiently short.

Noise Path Analysis is commonly used method to analysis noise transmission characteristics of a system. To analysis transfer paths of a system, it is necessary to know operating forces at each transfer path. The method to find out operating forces is divided into two methods. The one is a direct method which measures operating forces directly and the other is an indirect method which estimates operating forces mathematically. However, the indirect method is more commonly used because of the difficulty of measurement. This paper is focused on the indirect method and air-borne noise of a vehicle. Noise Path Analysis for Air-Borne Noise is applied to a real vehicle.

We employ a three-dimensional indirect boundary element method (BEM) to simulate temperature change around an underground liquefied natural gas storage cavern. The indirect BEM (IBEM) uses fictitious heat source strength on boundary elements as basic variables which are solved from equations of boundary conditions and then used to compute the temperature change at other points in the considered problem domain. The IBEM requires evaluation of singular integration for temperature change due to heat conduction from a constant heat source on a planar (triangular) region. The singularity can be eliminated by a semi-analytical integration scheme. However, it is found that the semi-analytical integration scheme yields sharp temperature gradient for points close to vertices of triangle. This affects the accuracy of heat flux, if they are evaluated by finite difference method at these points. This difficulty can be overcome by a combination of using a direct numerical integration for these points and the semi-analytical scheme for other points distance away from the vertices. The IBEM and the hybrid integration scheme have been verified with an analytic solution and then used to the application of the underground storage.

In printed electronics, printing rolls are used to transfer electronic ink onto a flexible substrate. Generally printing rolls are patterned in microscale by the indirect laser method. Since based on the wet etch process, the indirect method is neither environment-friendly nor suitable for making a printing roll with patterns narrower than $20{\mu}m$. In this paper, we have directly engraved micro-patterns into a Zn-coated metal specimens using a picosecond laser in order both to engrave $10{\mu}m$-wide patterns and to improve the pattern profile. Experiments showed that it is possible to engrave $10{\mu}m$-wide patterns with an a rectangular-shaped profile which is necessary for the dimensionally accurate printing.
