1,1,1 - 삼염화에탄의 합성공정개발

김재진,이화영,이기준,강희동 한국화학공학회 1976 Korean Chemical Engineering Research(HWAHAK KONGHA Vol.14 No.3

염화비닐 합성공정의 부산물로 생산되고 있는 1,1,2-삼염화에탄을 接觸分解하여 염화비닐리덴을 만들고 이 과정에서 생산되는 염화수소 가스를 이용하여 염화비닐리덴으로부터 1,1,1-삼염화에탄을 합성하는 공정에 대하여 연구하였다. 1,1,2-삼염화에탄의 분해에 사용된 촉매는 활성탄에 擔持시킨 鹽化바륨 및 鹽化銅으로서 20∼30% 염화바륨 담지촉매가 염화비닐리덴의 선택도에 가장 좋은 결과를 보여주었다. 반응온도 400∼500℃ 범위에서 염화비닐리덴의 선택도는 최고 35%까지 얻을수 있었다. 1,1,1-삼염화에탄의 합성에는 Friedel-Craft 촉매를 사용하였으며 1,1,1-삼염화에탄의 합성 반응은 염화수소 가스를 계속해서 과잉으로 공급할때 염화비닐리덴의 농도에 대하여 一次 반응이며 0.6%의 촉매농도 범위에서 촉매농도에 비례하는 것을 확인하였다. A process is developed for the synthesis of 1,1,1-trichoroethane from 1,1,2-trichloroethane, a byproduct produced in the vinyl chloride process. Catalytic dehydrochlorination of the 1,1,2-trichloroethane produces vinylidene chloride, 1,2-dichloroethylene and hydrogen chloride of these vinylidene chloride and hydrogen chlo ride react subsequently to form the 1,1,1-trichloroethane in a Friedel-Craft catalytic process. Barium chloride or copper chloride of 5 to 30 percent by weight supported on the activated carbon is used as catalyst. The selectivity for vinylidene chloride is attained up to 35 percent in the reaction temprature range of 400℃ to 500℃ using 20 to 30 percent barium chloride catalyst. It is also confirmed that the synthesis of 1.1.1-trichloroethane is a first order reaction with respect to the concentration of vinylidene chloride when excess hydrogen chloride gas is bubbled continuousley into the catalytic slurry reactor, and its rate is linearly proportional to the concentration of anhydrous aluminum chloride catalyst.

에멀젼형 오일 수용액에 관한 정밀여과 특성

정건용,김재진,김규진,Fane, Anthony G. 한국막학회 1998 멤브레인 Vol.8 No.4

에멀젼형 절삭유(Caltex, Trusol) 수용액을 공칭 세공크기가 0.22μm 인 Millipore사의 GVHP 막과 0.2μm인 SUS 관형막(Mott 사)이 설치된 dead-end 및 십자형흐름 정밀여과 시스템으로 각각 분리하였다. 오일입자의 분포는 0.07 내지 0.22μm의 분포이었다. 투과유속을 예측하기 위하여 cake 여과모델 (CFM)과 standard pore blocking 모델(SPBM)을 적용하였다. Dead-end 시스템에서 0.01 vol% 절삭유 수용액을 400 rpm으로 교반시켜 투과시킬 경우, 100 kPa 이하에서는 CFM 이 투과유곡을 잘 나타내었으나, 150 kPa 이상에서는 SPBM을 적용할 수 있었다. 운전압력을 60에서 200 kPa로 갑자기 증가시키면 분리막 표면에 형성된 오일층이 파괴되고, 다시 60 kPa로 감소시킬 때 반복하여 오일층이 형성됨을 알 수 있었다. 투과기구가 CFM에서 SPBM 으로 전환되는 이른바 임계압력을 추정하였으며, dead-end system에서는 약 100 kPa이었다. Reynolds 수가 7080인 십자형흐름 시스템에서 농도를 0.01에서 0.03 vol%로 증가시키면 입계압력이 약 100에서 150 kPa로 증가하였다. The cutting oil emulsion microfiltration was carried out on dead-end call and crossflow systems equipped with 0.22 μm GVHP Millipore and 0.2 m. Cake filtration(CFM) and standard pore blocking models(SPBM) were applied to predict the permeation flux. The permeation fluxes of 0.01 vol% oil emulsion followed CFM for dead-end system very well under the condition of 400 rpm and below 100 kPa. The SPBM was, however, suitable for the permeation flux at 400 rpm and above 150 kPa. The oil layer on the membrane surface was destroyed and reproduced repeatedly as operating pressure was suddenly changed from 60 to 200 kPa, and then returned to 60 kPa. Also, we estimated the critical entry pressure(CEP) which is changed from CFM to SPBM, and CEP for dead-end system was around 100 kPa. The CEP increased from around 100 to 150 kPa for the crossflow system as the oil concentration increased from 0.01 to 0.03 vol% when Reynolds number was 7080.

시간 제약 조건 하에서 저전력을 고려한 CLB구조의 CPLD 기술 매핑 알고리즘

김재진,김희석 대한전자공학회 2002 電子工學會論文誌-SD (Semiconductor and devices) Vol.39 No.8

본 논문은 시간 제약 조건 하에서 저전력을 고려한 CLB 구조의 CPLD 기술 매핑 알고리즘을 제안하였다. 제안한 알고리즘은 DAG로 구성된 회로에 대하여 각 노드들의 TD와 EP를 계산하여 분할함으로서 저전력을 수행하였다. 또한 CLB의 구조에 따라 매핑 할 수 있는 조건으로 입력과 출력의 수, OR-텀수를 고려하여 시간 제약 조건에 맞도록 매핑 가능 클러스터를 생성한다. 매핑 가능 클러스터들 중에서 저전력의 기술 매핑이 되도록 출력의 수가 가장 적은 매핑 가능 클러스터를 우선 매핑하고 시간 제약 조건에 만족하는 매핑 가능 클러스터를 선택하여 매핑 한다. 제안된 알고리즘을 벤치마크에 적용하여 실험한 결과 기존의 알고리즘인 DDMAP에 비해 46.79%, TEMPLA에 비해 24.38% 감소된 결과를 나타내었다. In this paper, we proposed a CLB-based CPLD technology mapping algorithm for power minimization under time constraint in combinational circuit. The main idea of our algorithm is to exploit the "cut enumeration and feasible cluster" technique to generate possible mapping solutions for the sub-circuit rooted at each node. In our technology mapping algorithm conducted a low power by calculating TD and EP of each node and decomposing them on the circuit composed of DAG. It also takes the number of input, output, and OR-term into account on condition that mapping can be done up to the base of CLB, and so it generates the feasible clusters to meet the condition of time constraint. Of the feasible clusters, we should first be mapping the one that has the least output for technology mapping of power minimization and choose to map the other to meet the condition of time constraint afterwards. To demonstrate the efficiency of our approach, we applied our algorithm to MCNC benchmarks and compared the results with those of the exiting algorithms. The experimental results show that our approach is shown a decrease of 46.79% compared with DDMAP and that of 24.38% for TEMPLA in the power consumption.

Recently Korea achieved a spectacular progress in economic growth. This essay is an outline study of various effects which were brought about in the process of the development. And the following are main contents of the essay. 1) The economic growth and the distribution of national income. 2) The increase in productivity and the distribution of its fruits. 3) The relationship among economic growth rate, the increase in employment, and productivity. 4) The trends of national income, total employees' real payment, regular employment and real wages. 5) The present condition of wages. Generally speaking of the conclusion, recent Korean economic growth brougtht substantial decrease in real wage per labor·But this undesirable aftermath of rapid industrialization was covered by an astounding increase in employment, accompanied by an increasing gap in income distribution. These all show that Korea is in her first stage of capital accumulation. It is quite natural that these phenomena are found in an overpopulated country like Korea. What is most needed in this situation is to fulfil social justice and fair opportunities for all participant in this development effort.

창업기업의 기술사업화 역량이 생존에 미치는 영향에 관한 실증연구

김재진,양동우 한국자료분석학회 2013 Journal of the Korean Data Analysis Society Vol.15 No.2

본 연구는 창업기업의 기술사업화 역량이 그들의 생존에 미치는 영향을 분석한 것이다. 본 연구표본은 2009년부터 2011년 말까지 기술보증기금의 창업모형으로 평가하고 보증지원한 20,303개 기업의 평가결과를 이용하였다. 분석방법은 로짓분석을 이용하여 기간을 1년, 2년 3년으로 구분하고 시간의 흐름에 따라 생존에 미치는 요인이 어떻게 바뀌는지를 확인하였다. 분석결과는 다음과 같다. 기술사업화역량이 생존에 미치는 영향을 분석하기 위한 로짓 분석에서 창업기업에 대하여 보증을 지원한 이후 1년 이내에서는 경영주역량, 기술성, 사업성이 생존에 유의한 정(+)의 관계가 있다. 2년 이내와 3년 이내에서는 경영주역량과 사업성만이 생존에 유의한 정(+)의 영향을 미치고 있다. 창업기업 초기에는 경영주 개인역량, 기술적 역량, 사업추진역량이 생존에 중요한 요인으로 작용하고 있지만 시간이 지날수록 기술, 시장보다는 경영주 개인역량과 사업추진역량이 기업의 생존에 더 중요한 요인이다. 일반적으로 시장성이나 기술성이 높은 기업이 생존에 유리할 것으로 추정할 수 있지만 본 연구에서는 생존에 유의한 영향을 미치지 않거나 미친다 하더라도 짧은 기간에 그친다는 것을 확인하였다. 본 연구결과는 자원이 취약한 창업기업 특성을 감안하여 정성적이고 비재무적인 측정도구를 활용하여 생존에 미치는 영향을 검증함으로써 창업기업의 지원대상 선별과 지원방향 결정에 도움을 줄 수 있을 것으로 기대된다. This paper empirically examines the impact of start-ups' technology-commercialization competence on their survival. This study utilizes, as the sample data, the 20,203 appraisal results of KTRS-Startup, the technology rating model through which Korea Technology Finance Corporation (KOTEC) has appraised and provided credit guarantees from 2009 to 2011. The research identifies which factors affect the survival of companies and how they change as the time passed by, as it adopts the logistic regression model, as an analysis tool, and divides periods into one year, two year and three year. The analyses are as follows: The result of this study shows that the survival of start-ups is positively correlated - in a statistically significant level - with the appraisal results on the business owner's capacity, technology level and business capability within one year after providing credit guarantees. Within 2 to 3 year providing credit guarantees, only business owner's capacity and business capability have a positive impact on the survival of start-ups. This study is expected to be helpful to screen the promising startups and decide government support to them in that it investigates how qualitative and non-financial measures affect the survival of startups as it considers the startups' situation lacking resources.

사과 수출 증대에 관한 조사 연구

김재진,나경수 경북대학교 1971 生産技術 Vol.5 No.-

Korea has exported 2~3per cent of her total apple product. And to earn dollars through increase in export is the most urgent task that Korean Economy faces. This research plans to find out bottlenecks of apple export and to build strategies to open up a new export market. In 1969, the loss pertaining to the apple export to Taiwan was 70~80 won per box and the loss to Singapore and Hongkong was 400~700won per box, and the losses were offset by the import o bannana amounting as much as 40 per cent of total export. This 40 per cent compensation seems not enough increase of export to Singapore and Hongkong. Retail price of bannana in Korea is several times as high as import price, because of the imposition of tariff as high as 60% and special tariff as high as 90%. So it is recommendable to increase the rate of compensation to more than 60% and to decrease the rate of tariff, in consideration of that the export price of Korean apple is higher than that of the competing countries. Hongkong market and Singapore market are flooded with the cheap apples of mainland China, and no rooms for Korean apples to go in. We can not expect any sudden increase in apple export to Taiwan. But if both governments try to increase the amount of trade in terms of reciprocal trade, it must be hopeful. Philippine is the best market for Korean apple. Since last year philippine government has set some limitation to apple import. But if our government try to negotiate with Philippine government it may be possible to export as much as 300,000~500,000boxes. The best way to export our apples to Vietnam is to let U.S.Army buy them. The ideal method of keeping freshness is to establish cold-chain system. But the most urgent administrative task is to cut short the terms of export procedure from 13~26 days of present day to 10~15 days, and to build a refrigerated store house as wide as 1,000 Pyong(坪) around shipping area. It is also necessary to inspect strictly right before shipping. It is also recommendable to lend the Export Industry Fostering Fund to apple traders with the interest as low as 6% a year.
