The current study investigated the relationship between image processed data and human visibility data for natural forest scenes from the perspective of color. In particular, the results indicated relatively low Pearson product-moment correlations between the color ratings obtained from the two methods used in the study. The first method measured the color content of slides using a image processing program, while the second used a panel of human judges to rate the color content of each slide.

Most of ground investigations can be grasped geological distribution which like rock name, geological structure, soil condition, underwater condition, land slide, ground cave-in, ground collapse by geological survey. But geological survey is limited to part region geological structure, not wide region. Therefore, Image Processing Method must need to grasp wide region geological structure. The object of this research is presented analysis data of geotechnical engineering in first step investigation.

The Paper presents theoretical and experimental investigation of plunger type water hydraulic pump (plunger pump). An analysis of Crank shaft for plunger pump is carried out. With this results, the optimal dimensions of plunger pump are determined. And performance test results about slide resistance, hydraulic leak test, efficiency-pressure. and flow-speed and flow-pressure are presented.

As human beings, it is in our power to take a correct turn, which would make the world safer, fair, ethical, inclusive and prosperous for the majority, not just for a few, within countries and between countries. It is also in our power to prevaricate, to ignore the road sings, and let the world we all share slide into further spirals of political turbulence, conflicts an wars.

Mr. Hur has developed the 7500KW permanent magnet synchronous generator. The 7500KW generator has dual blade system with vertical axis type generation module. The 7500KW generator will generating that it is too expensive and construction payment. The advantages of dual blade system are cheap in generation with better efficiency, and safety compact structure. But also this system has the expensive slide ring for to distribute electrical power.

This is the abstract of lecture on Electro-optic characteristics of D-KDP crystal and its application for high speed shutter made by Dr. Naomi Furuya; The professor of Yamanashi University in Kofu Japan on March 31, 1973 for KEEI in the auditorium of Korea Electric Company. His lecture is listened by KEEI members that KDP Z-cut crystal can be utilized as a high speed shutter of 10$^{-6}$ second, combining special camera and 2-3KV electrical impulse generator and also recording slide photographs on tungoten lamp crystal voltage and melting fuse phenomena due to over-current taken by this special equipment had been demonstrated.

For the production of complicated plastic parts in a cycle, a mold is needed.. The basic tasks of a mold are accommodation and distribution of the resin, shaping and cooling the melt and ejection of the molding. To achieve these goal a mold has several important parts and we classified types of molds. The 6 different major functions of a mold are explained and several types of molds are shown in her. I hope these explanation will help to understand injection molds for a design engineer.

The attempt to distinguish between graphite and domestic anthracite was means, especially electric resistance. The specific resistance values of various coals and graphites were determined by Wheaston Bridge equipped with more finely adjustable slide wire. The result of graphite was in the below of 0.08 ohm-cm and that of anthracite has $10^{-1}{\sim}10^1$ohm-cm range.

본 논문은 추락 방지장치가 형성된 창문에 관한 것으로, 일반적인 형태의 공동주택 여닫이 창문은 사각틀 형태로 된 창틀의 내 창문이 슬라이드 가능하게 끼워져 있고, 창문을 개방 시, 창틀에 해충방지용 방충망이 설치되어 있지만, 종래의 방충망은 구조적으로 매우 취약하여 찢어지거나 휘면서 창틀로부터 쉽게 이탈되어 쉽게 추락사고가 발생하였다. 이러한 문제점을 해소하기 위해서 본 기술을 적용한 창문 설치 시, 개방했을 경우에만 체인 안전망이 형성되고, 창문을 닫았을 경우에는 체인 안전망이 창틀 또는 창문틀에 수용되어 보이지 않게 되어 미관을 해치지 않으면서도 추락 사고를 방지하여 안정성을 보장하는 효과를 거두었다.
