  • To evaluate the feasibility of using lineaments for the interpretation of regional geological structures, the extracted lineaments from satellite image and surveyed surface geological features mapped in the field were analyzed for the Euiseong Sub-basin. The lineaments extracted from Landsat-5 TM images show primary directions of N20$^{\circ}$~30$^{\circ}$E, N60$^{\circ}$~70$^{\circ}$E, N60$^{\circ}$~70$^{\circ}$W, which represent the trends of faults, strikes, and joints. In the sedimentary formation in the northern part of Palgongsan Uplift Zone, primary directions of the lineaments are NNE and NWW, and NEE in southern parts. The analysis of satellite lineaments is proved to be very useful to study the large-scale structures and surface geology of the Euiseong Sub-basin, whereas the previous research using brittle tectonics approach was advantaged in the outcrop scale in interpretation.

  • This study was to propose an improvement direction in statistical indicators of public libraries to collect objective data from such libraries. This improvement direction was made by deriving from countable factors at the library. These were selected from various parts of the library sectors, such as the library-related laws, public library standard of our country, and statistical indicators of IFLA and other major countries. Also The these statistical indicator was compared to the current statistical indicator of public library in Korea. The results will be able to develop new draft of statistical indicator, which can be used in understanding the present situation of public libraries.

  • Most information systems are component-based and developed by outsourcing, and developed software is maintained integrative. However, studies on cost measurement indicators and cost estimation model have not been performed sufficiently, which are foundational to enhance the productivity and efficiency of maintenance. This study suggests indicators to measure maintenance cost for component-based software and examines maintenance cost estimation model of component software by the measurement indicators suggested. In order to generate the indicators to measure the component-based maintenance cost, the previously proposed indicators are summarized comparatively. To estimate the measurement indicators of component-based software, it makes a comparison of the previously proposed indicators and arranges them. We classify the measurement indicators by how to apply according to maintenance types of component software and then we propose the cost measurement indicators. Moreover, we propose the cost estimation model according to the maintenance types of component software using the suggested measurement indicators suggested. With the suggested estimation model, a case study is performed and its validity is verified.

  • In this study, two methods to evaluate the disassemblability of the parts are proposed, which are constructed from the concepts of ease-of-disassembly and disassembly time. A method to evaluate the disassemblability of the products is consequently developed using the concept of minimum parts. The methods are applied to evaluate the disassemblability of computer cases. The results show the conclusions that the new model has less disassemblability than the old one. These methods are expected to be used for the evaluation of the possibility of remanufacturing and recycling of a part.

  • A biological assessment of water quality was made at 9 sites of the Joyang-river and inflow streams located in Jeongseon-gun Gangwon-do, from June 2008 to September 2010. The investigation consisted of physico-chemical factors, biomass, and standing crops of epilithic diatoms. In addition, the community structure of epilithic diatoms was analyzed, and the water quality was assessed using DAIpo and TDI. The pH varied from 7.4~10.2 which is attributed to the Joyang-river area consisting of limestone. A total of 117 taxonomic groups of epilithic diatoms, including: 2 orders, 6 families, 23 genera, 95 species, 15 varieties, 2 forms, and 5 unidentified species, were found in the Joyang-river. 11 taxa, including Achnanthes laterostrata and Cymbella delicatula which live in neutral to alkali pH, were found. An indicator species of alkali waters, Cymbella delicatula, was routinely observed to have a relative frequency of over 10% in I3 and I4. In the result of the biological assessment using DAIpo, the Joyang-river was rated class A, with an average of 77.03 and inflow streams were rated class B with an average of 65.84. As for the results of TDI analysis, the Joyangriver was rated class A~B, and inflow streams were rated class A~D. Accordingly, the water quality of the Joyang-river was determined to be superior to that of inflow streams. Although the main stream showed low water quality at sites J2 and J3, correlating with a reduction in the quality of inflow stream, I1 in September 2009.

  • Climate change affects human and natural environment. Many countries, including Korea, are trying to develop climate change adaptation strategies to minimize adverse impacts of climate change. To deal with climate change efficiently, decisions have to be made among many options. The objectives of this paper is to analyzes methodologies for prioritizing climate change adaptation measures. Each methodology has strength and weakness and information requirements are differ. We find multi-criteria analysis is one of useful tools considering current level of understanding on climate change adaptation. We suggest climate change risks(timing, likelihood, intensity of climate change impacts), feasibility of policy (equity, main-streaming, democracy), effectiveness (economic effectiveness, co-benefits, propagation effects) of adaptation measures as main evaluation criteria of prioritization.

  • Recently deformed or destroyed of soundproof wall by local winds and typhoon has increased. This research proposed the estimation method of the design wind load of soundproof wall using spatial information analysis based on 1:5,000 digital map and performed comparative analysis with actual application cases. According to the result of quantitative evaluation using GIS, the surface roughness in the downtown area packed with buildings was III and the surface roughness in the suburban district with a relatively small number of buildings was II and the surface roughness in the district packed with open areas and typical farmhouses was I. This shows that the wind load of the soundproof walls reflecting the actual surface conditions was estimated. If the quantitative GIS analysis presented in this study is applied to wind-resistant design of soundproof walls, it is supposed that this will be helpful in more rational wind-resistant design by remedying the existing problem in which the wind load varies depending on designer's subjectivity.

  • The purpose of this study was to compare the health behaviors and health indices according to whether a percutaneous coronary intervention(PCI) was performed due to chest pain. This is a secondary data analysis study of nursing information questionnaires and electronic medical records of 247 chest pain patients in a hospital from January 2010 to December 2017. The participants were divided into non-PCI and PCI groups, and the health behaviors, blood pressure, and blood lipid levels were collected at the first hospital admission and re-admission. Collected data were analyzed using SPSS 24.0. As a result of the study, smoking and lipid levels were significantly healthier than the participants in PCI group during re-hospitalization. Non-PCI group had a high risk of smoking despite the high risk of coronary artery stenosis. It was found that continuous integrated management to promote health behavior is needed. The significance of this study was to identify the importance of health behavior in patients with the risk of cardiovascular disease.

  • 전력선 통신 기술의 발달에 따라 다양한 전력선 통신 핵심 기술들이 적용된 모뎀이 개발되고 있는 시점에서, 상용화에 앞서 모뎀 성능에 대한 실제적인 측정과 검토가 요구된다. 본 논문에서는 저압 전력선(옥내) 통신 테스트 베드를 구성, 이를 통해 모뎀의 네트워크 성능 지표들에 대한 실제적인 측정을 수행하였다. 저압 전력선은 220V저압에 옥내 배전선 약 16m로 구성되었으며, 측정된 네트워크 성능 지표는 RFC2544, RFC2285에서 권고하는 네트워크 성능 지표들 중, 일대일 처리율, 일대다 처리율, 다대일 처리율, 일대일 지연시간, 일대일 프레임 손실이다. 측정에 사용된 전력선 모뎀의 성능과 지표들의 측정값을 통해 모뎀의 성능과 속도뿐만 아니라 전력선 통신 어플리케이션 적용 여부 등 전력선 통신 시스템 개발과 상용화에 실제적인 검토가 가능하다.
