최근 10년간(2004~2013년) 국내의 조선소에서 발생한 해양오염사고의 건수를 연도별, 지역별, 조선소 작업별 및 오염물질별로 분석하였고, 이 분석 결과를 바탕으로 조선소 내 오염사고 방지 방안을 제시하였다. 전국의 조선소 내 오염사고는 10년간 총 103건이 발생하여 연평균 10.3건이었고, 연간 발생건수는 2004년 8건에서부터 점증하는 추세를 보이면서 2010년 23건으로 최고를 기록하였다가 다시 감소하는 추세로 바뀌어 2014년 9건을 나타내었다. 지역별 오염사고 건수는 부산이 32건(31%)으로 1위이고, 전남이 30건(29%), 경남이 21건(21%), 제주가 5건(5%), 강원과 경북이 각각 4건(4%), 인천과 충남이 각각 3건(3%)이었다. 조선소 작업별 오염사고 건수는 선박수리 작업이 60건(58%)으로 1위이고, 선박해체 작업이 25건(24%), 선박건조 작업이 10건(10%), 기타가 8건(8%)이었다. 오염물질별 오염사고 건수는 기름 및 유성혼합물이 59건(57%)으로 1위이고, 폐페인트 가루가 22건(21%), 쇳가루 및 용접슬래그가 13건(13%), 폐기물이 4건(4%), 폐FRP 가루가 3건(3%), 기타가 2건(2%)이었다. 국내 조선소 내의 오염사고를 방지하기 위한 방안으로는 (1) 관련 법규의 준수, (2) 조선소 밀집 지역에 대한 오염사고방지 실행계획의 수립 및 시행, (3) 특히 선박 수리 및 해체 작업을 하는 경우 조선소 내 기름오염방지 방안의 수립 및 시행, (4) 조선소 오염사고에 대한 민원 해결 대책의 마련, (5) 조선소 단속에 대한 국가 관리의 개선 등을 제시하였다. Data of pollution incidents which occurred in shipyards of South Korea for 10 years from 2004 to 2013 were collected and analyzed in order to propose the plans for the prevention of pollution incidents in shipyards. Total number of pollution incidents in shipyards was 103 cases over the nation of Korea for the recent 10 years and the average annual number was about 10 cases, and annual cases tended to increase from 8 cases in 2004 to 23 cases in 2010 and then to decrease to 9 cases in 2013. The location data of pollution incidents showed 32 cases in Busan metropolitan city (31%), 30 cases in Jeonnam (29%), 21 cases in Gyeongam (21%), 5 cases in Jeju (5%), 4 cases in Gangwon (4%), 4 cases in Gyeongbuk (4%), 3 cases in Chungnam (3%) and 3 cases in Incheon metropolitan city (3%). According to the data of work types of shipyards, 60 cases happened during the work of ship repair (58%), 25 cases during the work of ship breakup (24%), 10 cases in the course of ship building (10%) and 8 cases by others (8%). The data of pollutant type showed oil and oily mixtures to be 59 cases (57%), waste paint dust to be 22 cases (21%), iron dust and welding slag to be 13 cases (13%), wastes to be 4 cases (4%), waste FRP powder to be 3 cases (3%), and others to be 2 cases (2%). The plans for the prevention of pollution incidents in shipyards of Korea were proposed as follows; (1) Observance of the related laws and regulations, (2) Establishment and implementation of action plans to prevent areas dense with shipyards from causing pollution incidents, (3) Establishment and implementation of oil pollution prevention plans in shipyards, especially during the ship repair and breakup works, (4) Preparation of measures to solve civil complaints against pollution incidents in shipyards, and (5) Improvement in national management for the control of shipyards.

An experiment was conducted to compare the adsorption capacity and characteristics between activated carbon made of rice-hull(RHAC) and F-400 by Calgon to remove phenol, heavy metal and ammonia-nitrogen. While F-400 could not remove ammonia-nitrogen, RHAC was able to adsorb it. This is considered to be due to the ion exchange capability of SiO₂ remaining on the surface of RHAC. From the isotherm equilibrium test, it was found that RHAC has higher adsorption capacity than the existing activated carbon. In column tests, however, the slope of breakthrough curves of RHAC which represent the affinity of adsorbent, was observed to be more gradual than F-400. This may be attributed to the competitive reaction between ion exchange and physical adsorption. For heavy metals, F-400 would remove Cr and Pb except Cd, whereas RHAC was able to remove Cd, Pb except Cr.

SNMP를 연동한 콘텐츠 중심 네트워킹 망관리를 위한 이름 구조 및 이의 구현

Content-centric networking (CCN) is a future Internet technology to reorganize the paradigm of end-to-end communication of the current IP-based Internet architecture into a content-based paradigm. In managing such new networks, the network management is one of the most important functions. The standard for typical network management in existing IP networks is Simple Network Management Protocol (SNMP). Though there have been several works to implement network management functions on CCN, they have their own limitations to apply them to pure CCN operational environments. The basic reason of the limitation is that existing methods operate in an IP-overlay structure, or do not support push-type information exchange. In this paper, we propose a new naming structure that can accommodate both pull and push-type SNMP methods for CCN network management with SNMP. Then, methods to support GET and TRAP methods as well as a SET method of SNMP in the pure CCN environment using the proposed naming structure are proposed. We implement the proposed method using CCNx, and construct a CCN network testbed to validate the effectiveness of the proposed method by monitoring appropriate exchange of SNMP messages over the testbed. 콘텐츠 중심 네트워크(Contents-Centric Networking, CCN)는 현재의 IP 기반 인터넷에서의 단대단 통신 패러다임을 콘텐츠 중심으로 전환하기 위한 미래 인터넷 기술이다. 이러한 새로운 네트워크를 운영하는데 있어서, 망관리는 매우 중요한 기능들중의 하나이다. 기존의 IP 네트워크에서 전형적인 망관리 표준은 Simple Network Management Protocol (SNMP)이다. CCN에 망관리 기능을 구현하기 위한 많은 연구들이 있었으나, 이들을 순수한 CCN 운영 환경에 적용하는데에는 각각의 한계점을 갖고 있다. 이러한 한계를 갖는 주된 이유는 기존 방법들이 IP-overlay 구조로 운용되거나, push 형태의 정보 전달을 지원하지 않기 때문이다. 본 논문에서는 SNMP를 연동한 CCN 망관리를 위하여, pull과 push-type의 SNMP 메쏘드들을 CCN에서 모두 수용 가능한 새로운 naming structure를 제안한다. 그리고, 제안하는 naming structure를 활용하여 순수 CCN 환경에서 SNMP의 network 와 node의 상태 모니터링을 위한 GET과 TRAP 메쏘드 뿐만 아니라, 이들의 설정을 위한 SET 메쏘드를 지원하는 방법을 제안한다. 제안한 방법의 효과성을 검증하기 위하여, 제안 방법을 CCNx를 활용하여 구현하고 한 테스트베드를 구축하여, 테스트베드상에서 SNMP 메시지들이 정상적으로 교환됨을 보인다.

This paper treats the temperature effectiveness of the two-fluid counterflow regenerator in a rotary type. To avoid continual interpolation and to obtain the simple result in calculating that, it obtained the particular solution for the direct-transfer-type counterflow heat exchanger by the graphical procedures. Also, it introduced the empirical formula for the influence of the ratio of rotor matrix to minimum working fluid heat capacity rate with the particular solution induced. Particularly, substituting the published results of temperature effectiveness into the program, it obtained the simple and convenient equation which can applicate in the counterflow regenerator in a rotary type. To compare and discuss the results induced, selecting the regenerative air preheater and applying the their running datum and specifications to the related results, it shows that the above results are agree with the published results within absolute relative error, 3.0%.

The distributions of residual flows and dissolved oxygen concentration in the Yellow Sea were simulated and reproduced by an eco-hydrodynamic model which is composed of a three-dimensional hydrodynamic model and an ecosystem model. In order to estimate the environmental capacity of the Yellow Sea, the simulations for predicting the situation of unfavorable environment such as the formation of oxygen-deficient water mass in bottom layer were performed by controlling quantitatively the pollution loads of rivers flowing into the Yellow Sea. The field surveys and the seawater analyses were conducted over the Yellow Sea in summers, 1993 and 1994. The computed residual flows showed the counter-clockwise water circulation to exist in the surface and middle levels and no evident water circulation in the bottom level of the Yellow Sea. In the simulation of water quality with an ecosystem model, the more the pollution loads of 14 major rivers flowing into model region increase, the more evident appear the reductions of dissolved oxygen concentrations around the adjacent areas of estuaries receiving pollutants. In case the pollution loads of all 14 rivers become 7∼10 times as high as the present loads, the concentration of dissolved oxygen appears to be reduced to 5.0㎎ /ℓ or less in the bottom level of the water area being located eastward 60∼120㎞ away from the Changjiang estuary. Therefore, in order to keep the concentration of dissolved oxygen being 5.0㎎O₂/ℓ and above, which is the Korean criterion of the third class seawater quality, the environmental capacity of the Yellow Sea may be estimated to be 7∼10 times as high as the present pollution loads.
