기술사마당_기술해설 - 베트남 락지아(Rach Gia) 우회도로 사업 실시설계소개
강희철,Kang, Hee-Chul 한국기술사회 2010 技術士 Vol.43 No.4
Th Rach Gia Bypass Project, to be implemented under EDCF Loan VNM-12, constitutes a strategically important part of the Greater Mekong Sub-region Southern Coastal Corridor Project(the GMS-SCCP). The main goal of the GMS strategy is to promote sustainable economic growth, improve employment, and achieve poverty reduction by tapping the comparative advantages of Vietnam, Cambodia and Thailand. As a project manager who once took a responsible position for the completion of RGBP's detailed design, I would like to briefly introduce what our design team including the local sub-contractors had performed for the D/Design of this Project last year, especially in the field of highway, bridge and soft soil treatment method widely used in Mekong Delta area. With the performance of nearly two Projects due to the V.O. in one year on the prescribed time, it was a hard year but a rewarding one. To expand our horizon more about overseas projects, several recommendations for the brighter future of overseas projects are shown herein this paper.
70MIPS 이내에서 동작하는 MPEG-2 AAC 부호화 칩 설계
강희철,박주성,정갑주,박종인,최병갑,김태훈,김승우,Kang Hee-Chul,Park Ju-Sung,Jung Kab-Ju,Park Jong-In,Choi Byung-Gab,Kim Tae-Hoon,Kim Sung-Woo 대한전자공학회 2005 電子工學會論文誌-SD (Semiconductor and devices) Vol.42 No.4
MPEG-2 오디오 압축방식인 AAC(Advanced Audio Coding) LC(Low Complexity) 스테레오 부호화기를 고속으로 구현할 수 있는 칩을 32비트 DSP 코어를 기반으로 설계하고 0.25um CMOS 기술을 이용하여 제작하였다. 계산량과 메모리 용량을 줄이기 위하여 알고리즘 구현방법 측면에서 최적화를 하였으며, FFT(Fast Fourier Transform)를 하드웨어로 구현하여 고속화하였다. 제작된 칩의 크기는 $7.20\times7.20 mm^2$ 이었으며 등가 게이트는 약 830,000 이었으며 70MIPS 이내에서 AAC 부호화를 할 수 있음을 확인하였다. A chip, which can fast encoder the audio data to AAC (Advanced Audio Coding) LC(Low Complexity) that is MPEG-2 audio standard, has been designed on the basis of a 32 bits DSP core and fabricated with 0.25um CMOS technology. At first, the various optimization methods for implementing the algerian are devised to reduce the memory size and calculation cycles. FFT(Fast Fourier Transform) hardware block is added to the DSP core to get the more reduction of the calculation cycles. The chips has the size of $7.20\times7.20 mm^2$ and about 830,000 equivalent gates, can carry out AAC encoding under 70MIPS(Million Instructions per Second).
EDCF차관(借款) 하의 개발도상국의 해외토목 설계 절차의 이해
강희철,Kang, Hee-Chul 한국기술사회 2011 技術士 Vol.44 No.2
While performing the overseas projects in developing countries under EDCF loans with Korean civil design engineers as a project manager, I often used to find out and realize that lots of Korean engineers are not fully aware of what EDCF means and how EDCF funded projects are being implemented in developing countries. This implies that in the past, they have been concentrating on domestic projects only, not to mention have the rare opportunities to work in overseas projects. For these reasons, no wonder they neither pay a careful attention to the unfamiliar terms nor intend to try to realize them, even though such terms are fundamentals and important in overseas design works. With 'something will make it do'-like-attitude in our mind on site, nothing helps us at all. To help those who would like to understand and participate in overseas civil design works in developing countries under EDCF loans either as participants or as a future project manager, I introduce what EDCF means and how the procedure under these loans is being carried out, and they are briefly described herein this paper.
사혈요법과 기타 한방치료를 이용하여 치료한 만성 비염을 동반한 전증(癲證) 환자의 증례보고

Objectives: The purpose of this study was to investigate the clinical application of Korean Traditional treatment to Jeon-zeong(癲證) with Chronic hypertrophic rhinitis. Methods: In this case, a 25 years old male patient has suffered by schizophrenia for 2 years and by Chronic rhinitis for 9 months. During 171 days, we treated the patient with Korean Traditional treatment. Specially blood-Letting therapy helped the patient to decrease the auditory hallucination, catalepsy and retardation as well as the snuffles. Results: After treatment. the chief complain and accompanying symptoms were subsided and improved. And Personal and social performance scale was increased. Conclusions: According to this study, Korean Traditional treatment such as Blood-Letting therapy, acupuncture and heb-medication is effective for the cure of Jeon-zeong(癲證) with Chronic hypertrophic rhinitis.
니코틴 의존도에 따른 양생 실천 수준에 대한 조사 연구

Objectives: The purpose of this study is to investigate the practice level of Yangseng according to nicotine dependence. Methods: The subjects of this study were 137 male smokers in their thirties and forties, who visited Wonmi Public Health Center. They were evaluated with Fagerstorm`s test for nicotine dependence (FTND) and Tool in Measuring Yangseng (TMY). By FTND score, they were divided into three groups; the mild nicotine dependent group, moderate group and severe group. Results: In TMY score, there were statistically significant differences in the characteristics of Diet, Activity & Rest, Sleep and total score among the three groups. The value of FTND comparing the values of Mind, Diet, Activity & Rest, Sleep and total score in this study resulted in negative correlations, which showed statistical significance. Conclusions: The above results suggest that there are significant relations between nicotine dependence and the practice level of Yangseng. These results can be used for planning a smoking cessation program and a Yangseng health promotion program based on Korean traditional medicine.
