In the past, Korean English language learners focused on knowledge of grammatical structures. Thus Korean trained instructors, who focused on explaining the grammar structures, were seen as being preferable for teaching in EFL (English as a foreign language) classrooms. However, with the focus changed to speaking capability Koreans now desire 'fluent' English more than 'accuracy' seeing if possible (Mottos, 1997). Current study has been concerned about the issue of how non-native learners of English perceive the difference between native teachers (NTs) and non-native teachers (non-NTs) of English in the context of ELT classroom. The study explores the issues and problems the followed and how non-NTs can enhance teaching practice of speaking and listening lessons through multimedia application.

The purpose of this study is to analyze the knowledge and attitude of applicants on self-help teacher's program for arthritis patients. Subjects of the study constituted 407 applicants who attended the self-help teacher's program for arthritis patients. Self report questionnaires were used to measure the knowledge about arthritis and the attitude toward self-help education. In data analysis, SPSS PC 9.0 Program was utilized for descriptive statistics and one-way anova analysis. The results were as follows : Average age of the participants were 37, while 62% married, 62% had 4-year or above education, and 32.7% had experience of community health nursing. The mean score of knowledge about arthritis was 17.99/28 ; the mean score of applicants' appraisal on the arthritis patients' ability of self-help was 31.66/40 ; the mean score of applicants' attitude toward self-help education for arthritis patients was 35.64/56. According to regions of education for applicants' self-help program, there were not significant differences in applicants' knowledge and appraisal and attitude on self-help program.

As the interest in sensor networks has been increased recently, researches have been performed in many areas using sensor networks. In this paper, we propose and implement a lecture room control system based on a sensor network. It is possible to give an efficient lecture by collecting lecturers' lecture history information through the sensor network and controlling a PC, a beam projector, lights, etc. in a lecture room appropriately using the information. We construct a sensor network and perform experiments so that the proposed lecture room control system performs efficiently. Through the experiments, we obtained the optimal message generation period of the sensor node in a lecture room and the optimal number of sensor nodes deployed in a lecture room to communicate without any trouble between sensor nodes.

This paper evaluated the quality properties of Finex Water Granulated Slag fine aggregate as part of a study to recycle the Finex Water Granulated Slag generated in korea, and examined the availability as fine aggregate for concrete by comparing properties (properties of fresh concrete, mechanical properties of hardened concrete) of concrete using Finex Water Granulated Slag fine aggregate with properties of concrete using river sand as fine aggregate. From the results of this study, it was found that quality properties of concrete using finex water granulated slag as fine aggregate and concrete using river sand as fine aggregate are equivalent level.

In the present study, we comparatively investigated the microstructures of two hot-rolled stainless steel clad plates; STS 304L - low carbon steel A516-70N and STS 316L - A516-70N. The STS 304L/A516-70N clad plate (Clad_304L_Ni) had a Ni-interlayer between stainless steel and carbon steel and a 90 ㎛ thick deformation band of unrecrystallized austenite grains on the stainless steel. The STS 316L/A516-70N clad plate (Clad_316L) had no interlayer and almost fully recrystallized austenite grains. Clad_304L_Ni exhibited the thinner a decarburized layer in carbon steel and a total carburized layer in stainless steel than Clad_316L. However, a severely carburized layer in stainless steel was thicker for Clad_304L_Ni than Clad_316L. Hardness profiles near the interface of clad plates matched well with microstructures at locations where the hardness values were measured.

This study has been carried out to provide marketing materials concerning recognition of parents and students for operators of private cooking education institutes and useful information for the parents who are to send their children to such training institutes, by identifying the effects of the quality of educational services and educational environment of cooking education institutes on satisfaction and positive recommendation intention of trainees. Especially, educational services and educational environment of cooking education institutes that provide education to foster skilled workforce in specialized culinary area were analyzed in detail to draw effective data. Firstly, it has been studied if educational services of cooking education institutes such as educational contents, service of instructors and educational service quality had positive effects on the level of satisfaction about the institutes. Secondly, looking into effects of satisfactory environmental service of cooking education institutes, such as educational environment and quality of administration, on behavioral intention, it has been surveyed that all factors affected satisfaction of students. Thirdly, as for the effect of use intention of action of cooking education institute on positive recommendation intention of trainees, it has been shown that satisfaction with educational services and environment had an effect on positive recommendation intention as well as on intention of reregistration. Therefore, it can be suggested that marketing strategies and management strategies need to be established in a way that quality of education services and educational environment provided by cooking education institutes can render positive behavioral intention to customers of cooking education and the education market through differentiated strategy establishment.

It is estimated that over 2 million tons of non-ferrous wastes are generated after refining. Up to now, most researches were focused on extracting precious metals and there were very few research on the utilization of the slag byproduct. In this study, we studied to evaluate whether copper slag could be used as aggregates in concrete. Fresh mortar were evaluated on the particle size and replacement ratio of the copper slag with river-sand. Experimental results indicated that flow, air content and drying shrinkage of concrete varied with particle size, which confirmed that proper classification of copper slag is very important. And, setting time and unit weight of the concrete increased with replacement ratio. When particle size of the slag was similar to the river-sand, concrete with copper slag showed slump, air content, setting time, drying shrinkage and unit weight became larger compared to the concrete using river-sand only. Therefore, it is believed that proper classification and replacement ratio should be optimized for the effective use of slag in concrete.
