The investigated sector of self purification capability is the mid and up stream of Jungryang main stream which length is 6. 5 km (from the confluence of Backsuk stream and the main stream to the confluence of Dobong stream and the main stream) The self purification capability evaluated as two cases, they are untreated and treated through Eujungbu city sewage treatment facilities, DO model of Streeter and Phelps. The results are as follows, The K₁ value in Jungyang stream is 0.216 day^(-1) (20℃), K₂ value is 4. 050 day^(-1) (20℃) by Langbien and Durum equation and f value is estimated 18. 75 which appeared higher than the value in the unpolluted streams. The assimilative capability evaluated by DO model of Streeter and Phelps is approximately 21 percent of self purification ratio in the main stream, which length is 6. 5 km from the confluence of Backsuk stream and the main stream to the confluence of Dobong stream and the main stream. In the case of treated by Eujungbu city sewage treatment facitities is assimilative capability. By DO model of Streeter and Phelps, the evaluated value has approximately 50% of self purification ratio and DO value will be increased to 5. 3 ㎎/ℓ from 1. 37 ㎎/ℓ in the untreated of Eujungbu city sewage treatment facilities.

The Chungryang-stream is one of the tributaries of the Han-river which flows through the north-eastern part of Seoul city which is the largest one in Korea. The total length of the stream is 102.2 kilometers (main stream: 42.2 kilometers, its branch: 60 kilometers) and the study area is about 239 square kilometers with the population of 1.8 million. Major sources of pollution on the stream in study area are both of industrial and domestic waste water, which adversely affect the water quality of the down stream of the Han-river. The water quality measured by BOD_5 of the upstream of Chungryang-stream was about 7.0 milligrams per liter. However passing through the area of the Euijungbu, the water quality measured by BOD_5 was showing high concentration as about 40 milligrams per, liter due to the sewage from the Euijungbu city and the highly polluted water of Paeksuk-stream. No significant seasonal changes in DO concentration are shown in main stream except upstream and the ratio of T. coli/F. coli is 3. 4 in the upstream, 1. 6 in the midstream and 2.3 in the downstream. COD values of sediments range from 3. 0 to 384. 9 milligrams per liter and it is found a wide viriation of the values owing to the rainfall.

최근 고속철도는 선진국들의 차세대 교통수단으로 각광받고 있다. 속도와 수송능력뿐만 아니라 운행의 정확성, 접근성, 그리고 대기오염이 없다는 다양한 이유 때문이다. 이렇게 유용한 고속철도를 우리에게 알맞은 형태로 이용하기 위해서는 많은 연구와 기술개발이 필요하다. 따라서 우리는 철도선진국들의 고속철도 기술 개발 사례들을 비교, 연구하여 우리나라에 적합한 고속철도의 방향을 제시하고자 한다. The high-speed express railway has recently developed countries of the next-generation transportation in the limelight. Speed and accuracy of operation as well as delivery capability, accessibility, and a variety of reasons that he has no air pollution. Be aware that this useful form that suits us a high-speed railway to need a lot of research and technology development. We are therefore in developed countries are of high speed railway, comparison, researching the technology development cases where they would suggest to the direction of the bullet train conforming to our country.

방조제(防潮堤)의 설계(設計)를 위(爲)한 태풍(颱風)의 분석(分析)

The safety of shore structure including the sea dipe is largely affected by typhoon. Accordingly it is desirable to analize the typhoon and determine the wind direction and velocity for use in planning and design of the structure. This method was adopted for the design of the Yong San Gang Estuary Dam. A comparative study of the results of typhoon analysis with the meteorological data obtained through actual observation is summarized as follows; (1) 62% of the typhoons occur during May to June in a year, and 62% of the typhoons which have an influence on the Korean peninsula, especially the proposed estuary dam fsite, proceed eastward through the zone in lat. 36°-37°N. Such typhoons occur two to three times a year on the average. (2) Data on typhoon "SARL" were used as a model case in designing the estuary dam, where it was proved that a southwesterly wind had a maximum velocity of 30m/sec in case r=150km, α=120°. Within the range of 22°30'on the right and left side of the fetch line of the estuary dam, the wind direction varied SSW→SW→WSW, and the wind velocity varied 29m/sec→30m/sec→125m/sec. Such phenomemum lasted for five hours. (3) An analysis of data obtained during 44 years at Mok Po Meteorological Station shows that a wind with a velocity of some 25m/sec occurred twelve times in the S-direction and two times in the SW-direction, while that with a velocity of 30m/sec occurred three times in the S-direction, three times in the SSW-direction and one time in the SW-direction. The wind which had an influence on the estuary dam had a direction of SSW→SW→WSW and a velocity of min. 30m/sec. Actually, a wind with a max. velocity of 31.3m/sec occurred in the SSW-direction on March 15 and 16, 1956 where the mean velocity during two hours was 28m/sec and that during four hours was 24.6m/sec. (4) The data obtained through actual observation show that when the velocity is low, the wind with a fixed direction lasts long, and when the velocity is high, it is short-lived. It is difficult to determine the velocity of a wind which blows in a fixed direction for consecutive two or four hours. Therefore, the values obtained through typhoon analysis are larger that those obtained through actual observation, and hence, it is resonable to use the analyzed valuse for design of the estuary dam and shore structures. (5) The greatest effect was had on the estuary dam when typhoon was proceeding at a velocity of 29.71m/sec in the direction of α=120° (SW) at a point of R=150km from the center of the typhoon.

한상욱(Sang-Wook Han),박수리(Su-Ri Park),김병직(Byung-Jick Kim) 한국가스학회 2012 한국가스학회지 Vol.16 No.2

국내의 경우 연평균 22건의 지하 가스관사고가 발생하며 그중 5 건이 외부 굴착공사에 기인한다. 삼자 굴착사고로 인한 가스관 폭발사고의 예방을 위한 방안으로, RFID인식 기술의 적용에 대하여 연구하였다. 지상에서는 RFID는 원거리 인식이 가능한 장점으로, 물류 및 자재관리 등 다양한 분야에 널리 이용되고 있지만, 지하에서는 인식거리의 제한으로 연구 및 적용 사례는 거의 없다. 본 연구에서는 지하에서 투과율이 비교적 높은 900 MHz대역의 주파수 리더기로 지하에 매설되어있는 RFID Tag의 안정적인 인식거리 및 적용법을 연구하였다. 실제 가스관이 매설되어 있는 조건과 유사하게 흙, 콘크리트5 츠+흙, 그리고 지중수에 Tag를 묻고, 지상에서 RFID 리더기로 최대 및 가능 인식 거리를 측정하였다. 안정적인 인식 거리는 사전 사고 예방이 가능한 거리로 볼 수 있는 50, 45, 25 cm로 나왔다. 더하여 시제품 중에서 24 byte정보를 담을 수 있는 Tag 에 효과적으로 필요한 정보를 넣는 방법을 제안하였다. 본 연구결과는 RFID인식기술의 지하 가스관 적용은 가스 사고를 예방할 수 있을 뿐 아니라 가스관 관리에도 도움을 줄 수 있음을 나타낸다. According to the last 5 year statistics of KGS, there occurred 22 under ground gas pipe accidents per year in Korea. And about 5 accidents per year were caused from the third party digging. IT recognition technique could reduce such underground gas accidents. Among IT recognition technique, RFID is most poplar. In the air, RFID were applied to various fields including the distribution industry, but underground condition, the research and application cases of RFID were little This research was undertaken to see the applicability of RFID to underground gas pipe safety. By use of 900 MHz RFID reader and commercial metal tag, the stable recognition distance was measured in the similar underground condition of LNG pipe. Stable recognition depth of RFID tag were measured to be 50, 45, 25 츠 in the medium of soil, 5 cm-thick-concrete+soil, and water respectively. The measured distances were considered to be the meaningful distance to prevent the gas pipe accidents Also the efficient ways to input the required gas pipe data to the 24 byte metal tag were proposed. Application of RFID to underground LNG supply system will not only reduce the gas accidents due to third party digging but also improve the gas line maintenance efficiency.

현재 헬스케어 전문 업체가 제작한 어플리케이션들은 약품을 식별하는데 있어 사용자가 너무나 많은 정보를 입력해야 하며, 원하는 약품을 찾기가 쉽지 않다. 또한 정보를 입력한 후의 결과가 매우 광범위하며 약품을 찾다가 포기하는 경우가 많다. 본 논문은 사용자가 원하는 약품을 스마트폰 카메라로 촬영하면 약품위 정보를 자동으로 알려주는 약품 자동 인식 시스템을 개발하였다. 사람들이 쉽게 구매하고 자주 복용하는 약품들에 대하여 약품이 가져다주는 장점과 위험성을 알게 하고 다량 복용에 대한 경각심을 심어 주기 위한 것을 목표로 한다.
