In order to minimize emission of polychlorinated dibenzo dioxins and polychlorinated dibenzo furans (PCDD/PCDFs) from municipal solid waste incinerators, it is important to maintain optimized operating conditions along with the system modification/improvement. Operating conditions of MSW incinerator make very complicated influence on formation of PCDD/PCDFs in each unit apparatus. For revealing these influences, concentrations of PCDD/PCDFs are measured from the stack and from the fly ash, while monitoring the plant operating conditions. The effects are grouped into 3 main categories, combustion conditions, de Novo synthesis effects, and adsorption/destruction effects in the flue gas treatment system. Interpretation of the results showed that de Novo synthesis effect, reformation by metalic catalyst, especially Cu in fly ash in the temperature range of $250{\sim}500^{\circ}C$, is found to influence most dominantly on the concentration of PCDD/PCDFs. A plausible mathmatical model for predicting concentration of PCDD/PCDFs is proposed, and discussed.

I would like to propose the initiation of co-operating research about $\ulcornerIndustrial$ structure between Japan and $Korea\lrcorner.$ The purpose of this investigation is to study about appropriate system of industrial structure Japan and Korea including interactive relation. In future, tile interactive relationship of industrial structure should be desided by the investigation of a characterization about alocality, a racial character, a existence of resources, a weather, a history and natural features of a region. According to these investigation, frictionless structure of industrial society of each country will be born. The most appropriate researcher's group is Consulting Engineer's Association of each country, because they are independent from a national benefite and a profit of enterprise. According to the above reason. I propose to start the co-operating research project immediately.

PURPOSES: Regional offices of the Ministry of Land, Transport and Maritime Affairs use a computerized system called KAMIS so as to manage road equipment systematically. Road agencies can record number of operating days by equipment, actual working hours, accumulated operating hours (or distance) by equipment, and operating cost. However, KAMIS does not provide critical information, although it is strongly related to efficient road management equipment operation. In other words, road agencies do not know whether they have sufficient equipment to handle their actual work. METHODS: Therefore, this study suggests a methodology to evaluate for operational efficiency of road management equipment using analytical hierarchy process(AHP). First of all, estimated weights related criteria can be produced by AHP, and then use operational history by pieces of equipment. RESULTS: Results show that importance of management work can differ from weather conditions through five areas. CONCLUSIONS: Commonly, this results can imply to help save money for the purchase and maintenance of road management equipment, and they would improve the functional performance of KAMIS.

The study suggests a contract model of application operation through case study of A bank's IT outsourcing application contract based on workload. The IT outsourcing order form has a problem in that the scope of work is ambiguous due to the integration of operation and maintenance. In this study, application operation and maintenance were separated by referring to application operation history provided in ISO/IEC15504-5 standard. The scope of the IT outsourcing service was clarified by organizing the definition and detail activities of the application operation business. Application operation contract method has generally applied estimation method by the number of input manpower and period by agreement between buyer and client. As there is no activity to calculate the number of input manpower based on the operational work history and based on the standard workload per activity. In this case is not guaranteed due to the simple agreement between the contractors. In this paper, we propose an application operating cost estimation model that measures the size of the operating software using function point analysis that is the basis of application operation tasks. In order to verify the validity of the application operation cost model, we verified the correlation between the application size and the labor cost through regression analysis using SPSS.

중국의 조선기술은 유구하고 찬란한 발전역사를 가지고 있으며 세계 고대 조선기술사에서 아주 중요한 자리를 차지하고 있다. 지금까지 조선기술사의 연구경향은 서양 조선기술사에 편중되어 있었기 때문에 중국 조선기술사에 관한 연구는 이러한 결함을 보완 할 것이다, 인류사회의 발전과 더불어 조선기술도 급속히 발전되었다. 송대(960-1279년)에 이르러 중국의 조선업은 크게 발전되었으며, 그 특징으로는 선박의 대형화, 조선기지와 선박수량의 현저한 증가, 조선기술의 제고와 설비의 발전으로 나타난다. 송대의 조선기술은 원명(元明)시대의 조선기술 발전에 토대를 마련하였다. 따라서 교량역할을 한 송대의 조선기술을 연구함으로써 중국의 조선기술의 발전사를 알아볼 수 있을 것이다.

Purpose - The present study aims to examine the relationship between small enterprise start-up preparatory factors and increases in sales and operating profits, which are business performances utilizing the National Survey of Actual Conditions of Small Enterprises conducted by the Small Enterprise, Market Service. Research design, data, and methodology - Start-up preparatory factors were divided into six types; business type, start-up history, start-up motives, preparatory periods, and start-up funds to figure out the relationship between sales and operating profits with regression analyses. Regression analyses were conducted based on the foregoing with a view to identifying the effects of start-up preparatory factors on business performance. Results - Since start-up preparatory factors generally affect business performance, it was identified that start-up preparatory factors importantly affect operating profits and sales, which are business performances. However, start-up preparatory periods and the implementation of education among preparatory activities were shown to have no effect on business performances, and the effect of the ratio of start-up fund provided by the founder on operating profits was shown to be not significant. Conclusions - The present study comprehensively examined those start-up preparatory factors that have positive effects on business performances after start-up. The present study is meaningful in that it can provide positive implications for efficient start-up of small enterprises hereafter.

In this study, localized heavy rainfall occurred during the collapse of steep slopes adjacent to the construction site and to ensure the safety of residents to build an early warning system was performed. Forecast/Alert range was estimated based on vulnerability landslide map and past disaster history. And established a critical line in consideration of the characteristics of local rainfall and operating a snake line, the study calculated causing and non-causing points. Also, be measured in real-time analysis of rainfall data in conjunction with the system before the steep slope failure occurred forecast/Alert System is presented.

컴퓨터 사용의 역사를 보면 인터페이스 메타포는 사람들이 컴퓨터를 더 사용하기 쉽게 만드는데 쓰여왔다. 심지어 초기의 command line 인터페이스에서도 메타포를 사용해 왔었다. 사용자 인터페이스에 있어서 메타포는 사용자들을 시스템에 접근하기 쉽게 만드는 것을 도울 뿐 아니라 사용자들과 시스템과의 연결 통로라고 할 수 있다. 따라서 본 논문은 사용자 인터페이스에 있어서 성공적인 메타포 구축을 위해 conceptual model을 고려하여 Gestalt 원리를 활용한 지침을 제시함으로써 도움을 주고자 한다.
