해방 이후, 건설 상황에 관한 연구 : 1945-1960년을 중심으로

We were plunged in confusion directly after liberation. There was no new construction and there was only repair work. Both construction engineers and laborers were being threatened their living. The business world of construction was affected by the U. S. military administration. A 'hole-in the-wall' enterprise with no technique and no experience appeared in succession. Korean War (1950-1953) made the bussiness world of construction be ruined much more. during the period, many architects were kidnapped to the north. As soon as we reached a cease-fire agreement in July, 1953, the development works for rehibilation began to appear. The engineer cops of korean army and American army played an important role. As the repair works was processing, new korean construction was facing active aspects, but this was restricted. The law of construction was officially announced in March, 1958. The latter half of 1950s (1955-1960) was the starting point of new construction. The business world of construction had greatly affected public welfare and national rehabilation.
Optimization of Operation Parameters of 80-keV Electron Gun
김정동,이용덕,강형식 한국원자력학회 2014 Nuclear Engineering and Technology Vol.46 No.3
A Slowing Down Time Spectrometer (SDTS) system is a highly efficient technique for isotopic nuclear material contentanalysis. SDTS technology has been used to analyze spent nuclear fuel and the pyro-processing of spent fuel. SDTS requiresan external neutron source to induce the isotopic fissile fission. A high intensity neutron source is required to ensure a high fora good fissile fission. The electron linear accelerator system was selected to generate proper source neutrons efficiently. As a first step, the electron generator of an 80-keV electron gun was manufactured. In order to produce the high beampower from electron linear accelerator, a proper beam current is required form the electron generator. In this study, the beamcurrent was measured by evaluating the performance of the electron generator. The beam current was determined by fiveparameters: high voltage at the electron gun, cathode voltage, pulse width, pulse amplitude, and bias voltage at the grid. Fromthe experimental results under optimal conditions, the high voltage was determined to be 80 kV, the pulse width was 500 ns,and the cathode voltage was from 4.2 V to 4.6 V. The beam current was measured as 1.9 A at maximum. These results satisfythe beam current required for the operation of an electron linear accelerator.

근, 현대의 역사가 담겨진 건축물들은 그 '건축성' 의미 이상 값진 것이다. 일단 세워진 건물에는 정치, 사회 혹은 문화적 내용이 더해지기 때문이다. 건축을 일컬을 때 우리가 쉽게 하는 말은 '사람을 담는 그릇'이라는 것인데 이는 건축의 좋은 의미, 나쁜 의미를 가리지 않고 모든 사정을 담고 있다는 뜻이다. 세상사에 사람 그 다음 건축물만큼 현장감 넘치는 극적 요소도 없다. 근, 현대 건축물을 철거하는 것은 원초적으로 우리 건축사를 없애는 일인 것이다.
특별기고 : 동남아시아 도시,건축의 근대화 과정 - 우리 건축가의 새로운 역할이 기대되는 시점에서
김정동 대한건축학회 1997 建築 Vol.41 No.9
필자는 1980년 중반 이후 동남아도시건축 답사를 매년 거르지 않고 해 왔다. 필리핀, 베트남, 캄보디아, 태국, 말레이시아, 싱가포르 그리고 인도네시아 등이 그 주 답사지였다. 나는 답사중 내내 충격을 받았다. 그곳은 전혀 다른 세계였기 때문이다. 사전 지식이라는 것이 못사는 나라, 조그만 도시, 조금 안다고 하면 이국적 향취가 풍기는 적도의 나라라는 데 머물렀는데, 우리가 그들보다 잘사는 듯 신문에서는 떠들어댔지만 그것은 실례의 말씀이었다. 앞으로 5년도 채 안 걸릴 것 같은 위기감이 엄습해 왔다.
특집 : 한국의 서구건축 인식단계 - 한성순보의 수정궁을 중심으로
김정동 대한건축학회 1986 建築 Vol.30 No.3
소제는 한성순보에 나타난 수정궁의 보도 자체에 큰 비중을 두고 시작되었다. 사실 그 기사로 인하여 당시 한국인 누구에게 어떤 영향을 주게 되었는지를 밝히는 것은 어려운 일이다. 더우기 건축하는 사람 에게 직접적인 영향이 있었으리라고는 믿어지지 않는다. 그러나 기록상으로나마 수정궁이란 근대건축의 한 정점을 보도한 사실 자체를 확인함에 있어서만도 그 가치가 덜하지는 않을 것이다. 1960년대 일본을 떠들석하게 하던 Metabolist들도 수정궁의 융통성과 비영속성에 매료돼(목적이 변함에 따라 넓어지고 좁아질 수 있는 건축) 있었던 것은 보면 그 영향은 적지 않은 것이다.

Our construction work weakened under the rule of Japanese imperialism Formal construction company of korea appeared to Pusan in 20% of all the people. They were eimple laborers and their wages were a half in compareson with that of Japanese. The related laws and regulations of construction was made in 1921 and the institute of civil engineering and construction appeared. The institute of related labor was organized in Seoul in 1924 and in Tyoko the next year respectively. Japanese inperialism had concentrated on munition investment under war in the carly 1930's. Many militaries monopolized construction work, but Korean was excluded. The number of Korean constructor had some in creased in 1935. The number of Korean construction labor came to about 48 ten thousand persons from 1933 to 1938. Korea turned into the munitions industry complex of Japanese in about 1940.Materials plundering was strengthened and construction materials was distributed. Our construction engineers were within 25 persons in 1945. The minimum number of engineers was a colonist of our construction work.
