레이저 클래딩 중첩도가 표면특성에 미치는 영향

이제훈, 서무홍, 한유희 한국레이저가공학회 2000 한국레이저가공학회지 Vol.3 No.1

A 4kW RS840 CO2 laser with a powder auto-feeding apparatus has been used to deposit multiple overlapping tracks of Ni-base superalloy on to low carbon steel. It was found that the surface roughness(turbulence) of an overlapped cladding layer decreased with the increase of the overlapping ratio in an oscillating manner. When the overlapping ratio had values of 0.62, the surface turbulence was lowest. Overlapping ratio offer significant potential for improvement of materials surface properties such as corrosion performance and wear resistance. This paper reports that the overlapping ratio shows best corrosion resistance. The tensile residual stresses generated at the higher overlapping ratio(>0.45) and the element concentration of Fe increased in the surface layer at the lower overlapping ratio(<0.45) may lead to worse corrosion resistance.

Land use and social, cultural and environmental safety, which are adapted to natural environment, based on the traditional agricultural society, are on the verge of collapse because our rural community was developing around economy value. Rural landscape has not been certified compared with urban and natural landscape in importance by the standard of functional aspect, economic value and use demand, so cultural, historical, traditional and agricultural landscape native to rural community are not evaluated exactly. The Purpose of the study is a efficient plan and management for a essential rural landscape. Therefore We Make out a landscape diagram for efficient landscape plan and management and Selection of the Rural Landscape Management Area.

A novel Camera Calibration Method is proposed by employing the perspective transformation matrix with scale factors for the accurate Robot Vision System, where the calibrated scale factors are horizontal scale factor, computer image center coordinate, and camera lens distortion coefficient. By using those factors, the image coordinate with distortion in computer frame grabber is transformed to the undistorted coordinate, in which calibration is performed. To show the validities of the proposed method, several experimental results are illustrated with comparison of the other calibration methods.

1976年부터 1979年까지 慶北 漆谷카톨릭皮膚科病院에 來院한 外來患者中에서 臨床的 및 眞菌學的으로 頭部白癬으로 確診된 154例에 對하여 觀察한 成積을 다음과 같이 要約한다. 頭部白癬은 總外來患者의 0.19%에 該當하며 1976年부터 1978年까지는 큰 變動이 없었으나 1979年에 갑자기 2~3倍로 增加되었다. 男女의 罹患比는 7歲未滿에서는 큰 差異가 없으나 8~14歲群에서는 男子가, 高年齡群에서는 女子가 높았다. 그러므로 1961年以前에 比하여 男女間에 큰 差異가 없어지고 있다. 總分離菌 136株中 M. canis가 97株(71.3%), T. ferrugineum이 26株(19.1%), T. mentagrophytes가 10株(7.4%), T. rubrum이 3株(2.2%)이었다. 이 成績이 1961年前에 比하여 T. ferrugineum은 1977年부터 顯著히 減少되는 反面에 M. canis가 急增되어 主要菌의 交替現象이 일어나고 있다. T. ferrugineum은 14歲未滿의 男子에 많고 M. canis는 男女 모두 14歲未滿에서 많았으나 特히 女子에서는 7歲未滿과 高年齡群에 많았다. 特히 M. canis感梁이 7歲未滿 兒童에 많았으므로 앞으로 感染源인 고양이의 索出과 이에 對한 適切한 加療가 必要하다. Reports have been made of the detailed clinical and mycological observation on tinea capitis in the Taegu area during the period of 1954 through 1961. There had been, however, no follow-up studies on the disease until 1975. With the reports on the increasing incidence of Microsporum canis infections throughout the country, we suppose that the clinical features and the causative agents of tinea capitis may differ from those observed between 1954 and 1961. The authors observed 154 cases of tinea capitis at Chilgok Skin Clinic during the period from 1976 to 1979, clinically and mycologically. Tinea capitis occupied 0.19% of total outpatients in the clinic, and the incidence increased markedly during 1979. There was no general difference in incidence rates between both sexes of children, but a tendency was noted male children were predominant among the age group of 8 to 14, while female children were predominant among the age groups of under 7 and over 40 years. Among 136 fungi isolated from patients M. canis was most frequently found with 97 (71.3%) strains, and followed by 26(19.1%) of Trichophyton ferrugineum, 10(7.4%) of T. metagrophytes and 3(2.2%) of T. rubrum. These results indicate that T. ferrugineum which was the most predominant agent of tinea capitis before 1962, is decreasing markedly, while M. canis is increasing rapidly as the causative agent. The number of strains isolated in 1979 was more than the total number of strains in 1976 through 1978, showing that the predominance of causative agents in tinea capitis is changing toward M. canis, as compared with the distribution of agents before 1962. T. ferrugineum was frequently isolated from male children under the age of fourteen. M. canis was predominant in both sexes under the age of fourteen, but was predominant among patients under the age of seven and a higher age group in female.

The purposes of this study are to investigate perception and preference of Chinese college students for Korean Kimchi by a survey and sensory evaluation and to globalize and industrialize Kimchi in the world. A questionnaire survey was conducted on 588 students residing in Beijing. About 80% of all the participants knew what Kimchi was and 63.4% had eaten Kimchi before the survey. On their first impression of Kimchi, 43.6% of respondents answered that it was 'good', and 67.1% answered that their impression after eating Kimchi was 'good'. 51.4% of respondents, answered the nationality of Kimchi is 'Korea'. The most liked Kimchi is Baechu Kimchi, and they preferred the white stem of the Chinese cabbage. On their perception of Kimchi, 'Kimchi is a good side dish with cooked rice' was totally received point. The most well-known cooking method of Kimchi turned out to be Kimchi Chigae, As the results of sensory evaluation on several types cabbage Kimchies at room temperature, the most preferred Kimchi by the students was two-day old and made out of 5g red pepper. And two-day old Kimchi 10g red pepper and 2g shangchai added was preferred, too. But the six-day old Kimchi was disliked. The two-day old Kimchi made out of 10g red pepper preserved in the refrigerator was the most-liked. The dishes using Kimchi as the main ingredient are listed according to the students preference as follows : Kimchi Hundun, Kimchi Ddungchai, Kimchi Bokum, and Kimchi Ramen, and so on.

Purpose of this study is to prove the relationship among the amount of surface area, the visual complex and the visual preference of Buildings in the urban space using computer simulation. It has the same results as the previous studies. In the urban Environment, especially about buildings, basic data which make possible to apply computer simulation at environment analysis will be supplied. In order to investigate the relationship between the amount of surface area and the visual complex, the visual complex and the visual preference, graphic simulation has been proceeded. Graphic factors of simulation photos are determined on the point of shape and colors(about buildings, land, and sky) The result of the relationship of the visual complex and the visual preference, and the amount of surface area and the visual preference are found to be inverse U-shape, and the result of the relationship of the amount of surface area and the visual complex is proved by the result of regression. So the same result has been obtained in computer simulation.

제닉스 시스템의 커널에서는 한글을 읽거나 쓸수가 없으며 한글을 구현하기 위해 바이어스콜이나 비디오램을 직접 억세스하는 등의 컨트롤이 허용되지 않는다. 그러나 제닉스 시스템의 입, 출력 시스템을 잘 살펴보면 한글을 사용하기 위한 해결점을 찾을 수 있다. 영문 제닉스는 키보드에서 입력되는 8비트 코드에서 최상위비트를 무시하여 7비트로 스트립 시키는데 이것을 막고 제닉스가 FOH~FFH까지의 코드를 제어 코드로 사용하지 못하게 함으로써 모든 한글을 터미널상에서 사용 할 수 있게 된다. 한편 제닉스의 표준 메일을 이용 할때에는 80H 이상의 코드가 입력되면 모두 \와 8진수의 조합으로 변경시켜서 출력하는 C함수를 사용하기 때문에 이부분을 수정하고 한글 에코 명령이 포함된 쉘 스크립은 8진코드로 바꾸어 주는 소오스를 활용함으로서 제닉스에서 터미널을 이용한 조합형 한글의 구현이 완벽하게 이루어졌다. Hangul can't be read and used from the kernel of XENIX system. To embody Hangul, the control of direct access of BIOS call or video RAM is not permitted. But a solution to use Hangul can be found through the search of input and output system of XENIX system. English XENIX OS disregards MSB from 8bit code inputting from key board and strip 7 bit. To prevent this, stty-istrip command is used. And by using stty-ixion command not to use control code from FOH to FFH of XENIX, All of Hangul can be used at the terminal. To satisfy these conditions stty-istrip-ixon command is inserted at each user's profile. While sending the letter through the standard mail of XENIX, /user/lib/mail. local program is available. then Hangul is not supported on mail. local, the reason is that if the code over ASCII code 80H is inputted in the mail. local program. C function outputting through the change into the combination of all \and octal number is used, but by modifying mail. local, all of Hangul can be available, and the shell script containing Hangul echo command can treat Hangul at the terminal by using convc source which change source to octal code. In this way combinated Hangul using the terminal from XENIX OS ard completely embodied.
