5평 남짓한 사무실. 거래처 관리 직원 1명과 수출국 현지를 방문하는 에이전트 5명이 전부인 업체가 지난해 말 한국무역협회가 주관한 제41회 ‘무역의 날’행사에서 1백만불 수출탑을 수상했다. 중고 인쇄기기 수출 전문업체인 죽산기계(주)(대표 하큐 아이눌 에스)가 그 주인공. 중고 재단기를 비롯해 라벨인쇄기 등 을지로와 충무로에서 쏟아져 나오는 수많은 중고 기기들을 수출하고 있다. 수출국은 인도.방글라데시.베트남.말레이시아 등 동남아 국가들이 주류다. 거의 맨손으로 시작한 죽산기계(주)를 창립 7년만에 1백만불수출탑을 수상하게 한 하큐 아이눌 에스(39)사장의 말을 들어봤다.

Jigangkooksa's Monument at Beopchonsa is a monument representing the Goryeo Era, registered as the National Treasure No. 59. Haerin was a descent of a small regional clan, who overcame a number of challenges to become the leader of the nation at the age of 75. The tower and monument built after his death are among the finest works of the Goryeo Era. The Yongwha-world of the Jigangkooksa's Monument is the expression of a new utopia, which cannot be found in numerous Buddhist arts including Buddhist holy picture's art or other Codex. After passing through the pillar of cloud where 4 heavenly birds play, the new world of vault unfolds. Below are the 13 mountains which stand for 13th Heaven. In the center stands Tusita, the sky. On the top of Tusita is a Nagapuspa. The Nagapuspa in general has wooden pillars of treasure dragon patterns with dragonhead-shaped flowers on top. On the bottom, indrajala hang down. The Yongwha-world of the Jigangkooksa's Monument is carved with patterns related to Maitreya entering Nirvana. Jigangkooksa was active in the Moonjong Kingdom, the most prosperous times of the Goryeo Era, and led the publication of the Buddhism's Collection of Sacred Writings, the holiest work of the Goryeo people. At the time, people have offered on his tower a picture of him as the owner of Yongwha-world, with the utmost respect. This was the ideal utopia perceived by the people of Goryeo.

전국토가 약 18,000개의 크고 작은 섬으로 이루어진 인도네시아는 1960년대부터 위성통신 및 위성방송 기술을 적극적으로 도입한 국가 중 하나이다. 다른 국가와 달리 위성통신/방송망을 이용하는 것이 통신/방송용 송/수신탑과 광케이블을 설치하는 것 보다 유리했기 때문이다. 그리고 그 중심에는 인도네시아 국립항공우주연구소(LAPAN)이 있다.

전기설계 및 감리자는 그 건축물의 목적과 사용용도 그리고 계획설계자의 의지를 충분히 파악하지 않으면 좋은 설계와 감리가 될 수 없다. 건축물이란 일단의 대지 위의 지붕과 벽 또는 기둥으로서 거주 작업, 저장, 등의 용도에 쓰이는 것을 말한다. 또 여기서 부속되는 대문, 담장, 굴뚝은 물론 지하실, 지하상가와 같은 지하구축물과 탑비, 기념상, 선전탑, 기타 지붕과 벽 등이 없는 것이라도 여기에 포함된다.

Granular activated carbon(GAC) adsorption is one of the best available technology to remove synthetic organic chemicals(SOCs) from water supplies and wastewater. In order to satisfy enviromental criteria and reduce GAC treatment cost, optimal study of reverse stratified tapered adsorber(RSTA) has been conducted. The RSTA was found to provide on increase in breakthrough time when compared to a conventional cylindrical adsorber(CA). Through the RSTA optimal experiment, optimal mean bed velocity was decided 19.10cm/min and optimal angle was decided RSTA($3.0^{\circ}$). Adsorption efficiency was increased with increasing activated carbon doses and the number of activated carbon layers.

실험실규모(0.5Nm$^3$/hr)의 이산화탄소 연속흡수분리장치의 실험결과를 바탕으로 Bench규모(5Nm$^3$/hr)의 이산화탄소 연속흡수분리장치 설계하였다. MEA용 이산화탄소 연속흡수분리 장치를 4개의 흡수탑과 2개의 탈거탑을 연결하여 각각 독립적으로 실험할 수 있도록 장치를 제작하고 실험변수에 따른 이산화탄소의 흡수분리효율을 측정하였다. 설치된 실험장치에 대하여 주어진 실험범위에서 실험한 결과, 이산화탄소 제거율이 45~100%에 존재함을 확인하였다. 실험결과와 설계기준을 고려한 scale-up factor는 설계결과와 실험결과를 종합하였을 때, 각각 1.00~1.85인 것으로 산출되었다.

This paper presents a walking guidance system for blind pedestrians in an outdoor environment using just one single camera. Unlike many existing travel-aid systems that rely on stereo-vision, the proposed system aims to get necessary information of the road environment by using just single camera fixed at the belly of the user. To achieve this goal, a top-view image of the road is used, on which obstacles are detected by first extracting local extreme points and then verified by the polar edge histogram. Meanwhile, user motion is estimated by using optical flow in an area close to the user. Based on these information extracted from image domain, an audio message generation scheme is proposed to deliver guidance instructions via synthetic voice to the blind user. Experiments with several sidewalk video-clips show that the proposed walking guidance system is able to provide useful guidance instructions under certain sidewalk environments.

Enzymatic hydrolysis of insoluble cellulose was performed in a bubble column with tangential flow ulrafiltration membrane unit. The reactor was operated in a batch mode as well as semi-continuous and continuous with continuous removal of products through the tangential flow ultrafiltration membrane. The optimum superficial gas velocity was 1-3cm / sec so as to avoid bubble coalescence and enzyme denaturation. In continuous and selni-cotinuous process, the conversion was gradually increased but the total reduced sugar concentration was drcastically dereased with the dilution rate. It was concluded that the bubble column attaching tangential flow ultrafiltration membrane unit was effective on continuous hydrolysis of cellulose and recovery of enzyme.

Aiming at the treatment of large volumes of gas with a low concentration of poorly water soluble VOC(Volatile Organic Compound), a new system is proposed: the combination absorption tower/bioreactor. In the scrubber part of the bioscrubbing system, the contaminating compounds are absorbed in a aqueous phase. The contaminated scrubbing liquid is transported to the bioreactor, where the compounds are biodegraded by aerobic microorganisms (mainly to carbon dioxide, water, and biomass). In this study, separation of a volatile organic compound(VOC) out of a waste gas stream has been carried out using a re-cyclable high boiling point extrant(HBE). The liquid stream containing a high boiling point entrant(HBE) scrubs the gas stream in a direct gas-liquid countercurrent contacting operation in a packed tower for the removal of said component from the gaseous stream. A packed-bed column using Pall Ring was set up in order to simulate practical conditions for the scrubbing tower. The liquid stream transported to the bioreactor is recovered and recycled to the scrubber. The model gas, which contained 400 mg/$\textrm{m}^3$ of toluene, at a rate of 100 L/min, flowed into the packed column where the scrubbing liquid trickled over the packing in countercurrent to the rising gas at 10~15L/min. The bioscrubber designed for large volume air streams containing VOCs showed removal efficiency up to 80% in an optimum operating conditions during the tests fer removing toluene from an air stream by scrubbing the air stream with HBE.
