Conventional engineering education models have fallen to give satisfactory results to enterprises. So this paper deals with the new engineering education system, Engineering House, to overcome it. EH is made of three spaces and three concepts. Concept means system. Three concepts are things about a education program, a research cooperation, a open-door policy of EH facilities. First of all, Education system for undergraduates is most important of all. We intend to give them chances for real engineering experiences. Specialist from companies are participated in the education. The second is a research network. EH is managed by two or three professors together and their researches are carry out with companies's researcher. Key-point is doing all together. The third is service system for regional enterprises. EH's facilities are opened. Our students and professors are supporting directly. Mainly high price measuring machine is used. Like these, networks with companies are very helpable for undergraduate's educations and job connections. These are the work based learning system. Engineering House system look forward to getting to good program for undergraduate, based on the co-operation between university and enterprises.

Center Distance Finding (CDF) is a technique to find the sphere diameter by measuring the distance between two contacting spheres. The focal spots of the sphere clusters are formed in the back-focal plane by the transmission-mode optical microscope with the pseudothermal illumination source. Digital images taken by the CCD camera were processed by the software called Global Lab Image. The centers of the focal spots are found and the spot positions are expressed in terms of the CCD pixel elements, whose coordinate are calibrated by a heterodyne interferometer. The new CDF measurement system has been developed, which are more advantageous in time and convenience than the existing system, while the measurement uncertainly remains sufficient for its use as a magnification standard for optical microscopy. Two kinds of polystyrene spheres whose nominal diameters 3 and 10 $\mu\textrm{m}$ (NIST SRM 1962 and 1960) are measured with the uncertainly less than 1% at the confidence level of 99%, and the results are compared with the results of National Institute of Standards and Technology.

Taekwondo has developed into a global sport that sports 80 million people from 208 countries around the world. Korea is the mother country of Taekwondo, and there are many international Taekwondo events in Korea. As important as the image of Taekwondo contents, it will be operation plan and management for event facilities. In particular, safety management for participants is more important than anything else. In case of Taekwondo where there are many national events, there are many foreign visitors, so safety management in facilities and running programs needs to be important. In this study, we conducted in - depth interviews with experts with a career in Taekwondo events. Based on the in - depth interviews, we analyzed the safety management problems of the international Taekwondo events and suggested improvement directions to overcome them. Based on the results of these researches, the improvement direction of Taekwondo event safety management proposed in the first category is a demand for improving safety and injury related system construction. The second category, the safety improvement of visitors, is to secure professional manpower and secure budgets. Also, what is important in the third category, facility safety area, is the proposal to introduce facility safety certification system.

This study has been carried out to provide data for the workforce by analyzing personnel status of medical device manufacturers, level of difficulty in securing human resource, reason for difficulty in securing human resource, resignation rate, and recruitment methods. Results, medical device manufacturers are required overseas sales personnel responsible for international certification and exported, regardless of the production item. And the company is located in the metropolitan area did not facilitate a secure workforce. Medical device manufacturers have difficulties in securing personnel, regardless of the employees and sales. In particular, Class 3 production company was more difficult. The reason that it is difficult to secure the human resources is attributable to the poor working conditions of the private companies and there is a few possible employees equipped with the job competency demanded by corporate entities. With respect to the analysis on the retirement rate, the larger the company scale and the more the employee number, more difficulty is experienced in the human resource management. Therefore, for any medical device manufacturers with large organization scale, it would be critical to introduce appropriate human resource management program.

The purpose of this study was to develop and present the accreditation criteria for engineering technology education programs in junior colleges. Research methods used in this study were review of related literature, experts discussion, and Delphi technique. Especially, Delphi technique was the major research method of this study. The Delphi surveys were taken for about seven weeks and three rounds at a higher level of expert participation. Major results of the study were as follows: 1. It proved that thirty six of total forty items had the content validity as the accreditation criteria of engineering technology education programs for junior colleges. CVR(Content Validity Ratio) of four items were below .33 and eliminated four items from the final accreditation criteria. 2. It proved that total Cronbach ${\alpha}$ was very high .9142 and reliability was very high all over items. It proved that six items made worse reliability, therefore it was desirable to exclude six items for increase of reliability. But the final accreditation criteria included six items, because they had a high validity as well as increasing rate of Cronbach ${\alpha}$ was very low with the exception of them. 3. Items of high importance were drawn out through analysis of importance. It proved that thirty of total forty items were more than 4.00 average in importance and ten items were less than average. 4. In conclusion, the final accreditation criteria were developed and presented through such analysis of validity, reliability and importance.

Recently, The wide range of the Internet applications and the related technology developments enabled the ease use of the digital multimedia contents (fixed images, movies, digital audios). However, due to the replay ability which the contents may be easily duplicated and not only the duplicates are capable of providing the same original quality. There are mainly the encipher techniques and the watermarking techniques which are studied and used as solutions for the above problem in order to protect the license holders' rights. To the protection of the IP(Intellectual Property) rights of the owner, digital watermarking is the technique that authenticates the legal copyrighter. This paper proposed the watermarking algorithms to watermark the 256 gray logo image and the color image by applying the wavelet transformation to the color stand-still images. The proposed algorithms conducted the watermark insertion at the LH frequency region among the wavelet transformation regions (LL, LH, HL, HH). The interleaving algorithms which applied in data communication was applied to the watermark. the amount of watermark increased which consequently caused the PSNR to decrease but this might provide the perseverance against the external attacks such as extraction, filtering, and crop.
