  • 본 논문은, 시설물안전법의 적용을 받지 않아 안전사각 지대에 놓여 있는 중소규모 교량들의 유지관리 전략 수립시 기초자료로 활용할 수 있는, 중소규모 교량 성능평가 우선순위 결정 방안을 제시하기 위해 실시하였다. 이를 위해 취약도와 영향도를 기반으로 하는 위험도 지수를 산출하고, 산출된 위험도 지수에 따라 이들 교량들을 성능평가 즉시실시교량, 단기실시교량 및 관찰교량으로 구분하여 제안하고, 실제 공용중에 있는 중소규모 교량에 적용하여 제안한 방안의 현장 적용성을 확인하였다. 연구결과, 여기서 제시된 방안은 향후 중소규모 교량의 유지관리 전략 수립에 적절히 활용되어 중소규모교량 사고 방지 및 유지관리 예산절감에 기여할 수 있을 것으로 판단되었다.

  • 방범용 CCTV는 지속적으로 증설되고 있으나 설치 위치 결정에 대한 가이드라인의 부재로 범죄 발생 다발지역과 무관한 위치에 CCTV가 설치되는 경우가 많다. 이에 본 연구에서는 도시공간빅데이터를 활용하여 CCTV 우선설치지수를 개발하고, 사례지역에 시범 적용하여 적용 가능성을 타진하였다. CCTV 우선설치지수는 범죄취약지수와 감시취약지수로 구성하였으며, 각각 머신러닝 알고리즘을 통해 예측한 그리드별 범죄발생건수, 가시권 분석을 통해 산출한 그리드별 감시불가면적의 비율을 활용하여 산출하였다. 지수를 시범지역에 적용한 결과 CCTV 가시권 분석에 Viewshed 기능을 활용함으로써 기존 버퍼 기능 활용 시 감시면적이 과대 추정되었던 문제를 해결할 수 있었다. 또한 해당 지수를 적용하여 CCTV 설치 위치를 결정할 경우, 감시면적을 효율적으로 개선 가능하다. 본 연구의 CCTV 위치 결정 프로세스에 따라 사례지역에 신규 CCTV를 추가 설치할 경우, 도로면적 대비 감시면적이 43.25%에서 83.73%로 증가하였다. 따라서, CCTV 우선설치지수는 스마트안전도시 조성을 위한 효과적인 의사결정 도구로 활용될 수 있을 것이다.

  • The objective of this paper is to design a Goal Alternatives Disposition System having three main subsystems for setting, evaluating and selecting goal alternatives. For setting of goal alternatives, System Alternatives Tree(SAT) structure will be developed, which has a computation algorithm for setting decision alternatives by the concept of System Priority Number(SPN). For evaluating and selecting of goal alternatives; First, Normative and Exploratory Priority Indices which consider technical performance to the goal, cost and feasibility are developed respectively. Second, Integrated Priority Index is built up to determine the total priority of the Goal Alternatives Disposition(GAD) system. For the design and verification of the GAD system, technological forecasting structure theory, systems engineering methodology will be used.

  • This paper addresses the problem of period and priority assignment in networked control systems (NCSs) using a fixed priority scheduler. The problem of assigning periods and priorities to tasks and messages is formulated as an optimization problem to allow for a systematic approach. The temporal characteristics of an NCS should be considered by defining an appropriate performance index (PI) which represents the temporal behavior of the NCS. In this study, the sum of the end-to-end response times required to process all I/Os with precedence relationships is defined as a PI. Constraints are derived from the task and message deadline requirements to guarantee schedulability. Genetic algorithms are used to solve this constrained optimization problem because the optimization formulation is discrete and nonlinear. By considering the effects of communication, an optimum set of periods and priorities can be holistically derived.

  • The purpose of this research is to provide a basic knowledge to open up for undeveloped park in process of the park policy establishment by setting up the priority of park development and valuation factor, valuation index as well as building a basic material to undeveloped neighborhood park in Daegu Metropolitan City. Thirteen urban neighborhood parks(1,841,663$m^2$) in the Daegu Metropolitan City were selected for this study. Analyzing and reviewing the previous research and literature review were conducted, and the evaluation index and analysis criteria were constructed to decide the development priority of parks. The results of this research are as follows; 1) Following to the result of the expert questionnaire test in order to estimate weight of valuation factors. It had a high score in available population, and estimated amount of the gross compensation, unpurchased land rate. On the other hand park rate of autonomous district, altitude, rate of population increase in autonomous district and a low score. 2) Generally, most f the plain type parks had a high score in the Sea level, land using pattern, an estimated amount of the gross compensation, but hill type parks had a high score the rate of green covered, park area for one person of administration building. 3) Daebong, Soosung, Dosan, 2.28 youth, Kyungnam parks were selected high priority. Soochang, Donsibong, Janggi, Dongin parks were selected middle priority. Bokhyun, Galsan, Manchon, Gusoosan parks, which were selected low priority. This research for undeveloped park is a basic research step to open up. Three many difficult things in shortage of the basic material for building valuation factor and measuring of the method measurement. The application of weight which make a decision importance among the valuation factor should have ore reasonable study and more scientific research from now because there still remains a lot of shortage of positive materials in there.

  • Purpose - Indonesian economy often receives negative impact from external factors, particularly through trade linkage. To mitigate that impact, the export market and product diversification should be established. Latin America is one of the potential regions to augment the Indonesian export market. Research design, data, and methodology - This study attempts to classify the potential market and product for Indonesian export, particularly in Latin America, by using panel regression, trade complementarity, and export similarity index over the period 2000-2015. Regression was also used to examine whether the presence of the Indonesian Trade Promotion Center (ITPC) can support diversification. Results - Based on regression results, those indexes established Chile, Uruguay, Suriname, and Ecuador as the priority countries with the products: animal and vegetable oils, fats and waxes; chemicals and related products; miscellaneous manufactured articles; commodities and transactions. Conclusions - The results of the regression concludes that the trade complementarity index gave a significant positive effect to boost Indonesian export, whereas, the export similarity index gave a significant negative effect. The regression also conclude that ITPC gave a significant positive impact on Indonesian export. For instance, the government should prioritize those countries and products and also develop ITPC there to optimize Indonesian export.

  • We tried to evaluate frequencies and severities of malocclusion of various socioeconomic areas according to growth and development. To obtain objective validity, we used Handicapping Labiolingual Deviation (HLD) suggested by Draker, Treatment Priority Index (TPI) by Grainger, Handicapped Malocclusion Assessing Record (HMAR) by American Dental Association and American Association of Orthodontist. Seoul and Kwangju were selected as an urban group, Ahnyang as an middle socioeconomic group and Hwasun near the Kwangju area as an rural group. 140 (male 63, female 73) of 5th grade in 'E' elementary school students in Seoul, 202 (male 101, female 101) of 'S' elementary school students in Kwangju, 207(male 105, female 102) of 'H' elementary school students in Hwasun, and 100(male 49, female 51) of 'M' elementary school students of in Ahnyang of all the same grade were analyzed and we obtained the results as follows; 1. TPI, HLD, and HMAR showed high coincidence and reproducibility between different observer. (p<0.01) 2. In comparison of TPI, HLD, and HMAR according to clinical decision, there was statistically difference between each other. (p<0.01) 3. As the severity of malocclusion increases there was high correlation between TPI and HLD, and between HLD and HMAR (p<0.05) 4. With respect to differences between areas in TPI and HLD, there was statistically difference between Ahnyang and other areas. 5. In Seoul as an urban group there was a high incidence of periodic checkup and history of orthodontic treatment than other area. 6. Mode of feeding and posture during sleeping did not affect the severity of malocclusion. As a conclusion, TPI, HLD and HMAR are so reproducible and coincident that they can be used as a guide on evaluating the frequency and severity of malocclusion and determining the priority of orthodontic treatment to determine the need and supply of orthodontic treatment. Furthermore these indices can provide objectively valid data for establishing public health problem solution.

  • 기후변화로 인한 이상기후 현상 증가와 도시화로 인한 불투수면의 증가로 인해 유역 물순환 관리 패러다임이 변화하고 있는 실정이다. 국내외에서는 물순환 왜곡현상을 억제해 줄 수 있는 저영향개발기술을 기반으로 연구가 지속적으로 진행중이다. 본 연구에서는 저영향개발 적용을 하기에 앞서 물순환 왜곡현상을 반영할 수 있는 요소 P, S, R값을 산정하여, 낙동강 유역을 대상으로 148 소유역별 PSR 지수를 산정하였다. PSR지수는 토지피복도 1975년을 기준으로 2019년 현재까지의 불투수면 변화율을 나타내는 압력지수 P, 기준에서 현재까지 각 소유역별 물순환 변화율을 나타내는 현상지수 S, 현시점에서 저영향개발 적용가능 면적 대책지수 R을 산정하여, 표준거리 d값 산정을 통해 PSR지수를 산정한다. PSR 지수값이 낮을수록 우선 관리 유역에 해당하며, 물순환 회복 우선 관리 유역으로는 1(서낙동강A), 2(낙동강하구언), 87(신천하류), 90(금호강하류), 91(진천천), 147(서낙동강B) 등 순으로 산정되었다. 대권역내 소유역별 물순환 우선관리 순서에 따라 효율적으로 저영향개발요소를 적용하면 물순환 왜곡현상 회복에 기여할 것으로 사료된다.
