  • Climate change is one of the most discussed issues in international for a today. Evaluating the effect of climate change at a regional level and setting up an appropriate policy to address the issues associated with climate change require a proper evaluation process on the climate change and adaptation projects already implemented. Although various evaluation approaches to climate change adaptation programs have been proposed, it is rare to find a proper systematic approach to evaluating the reliability of those climate change adaptation programs. In the current situation regarding the system to evaluate climate change adaptation programs, the purpose of this study is to suggest a theoretical and standardized evaluation system on the reliability of climate change adaptation schemes. The new approach suggested in this paper will be appropriate when requiring a confidence level for adaptation programs that are specially localized and categorized. Using various quantitative and qualitative evaluation methods with the inherent reality mechanism, we provide a conceptual framework to measure the reliability of climate change adaptation programs with a flexible adjustment process. With the proposed framework, it is possible to provide the level of confidence on the results collected from the evaluation systems and construct a standardized, system-wide assessment procedure toward climate change adaptation policies. By applying this approach based on scientific evidence on the reliability of climate change adaptation policies, appropriate and efficient climate change adaptation programs will be properly designed for and implemented in Korea.

  • This paper presents the depth evaluation for object detection by automated assembling robots. Pattern distortion analysis from a structured light system identifies an object with the greatest depth from its background. An automated assembling robot should prior select and pick an object with the greatest depth to reduce the physical harm during the picking action of the robot arm. Object detection is then combined with a depth evaluation to provide contour, showing the edges of an object with the greatest depth. The contour provides shape information to an automated assembling robot, which equips the laser based proxy sensor, for picking up and placing an object in the intended place. The depth evaluation process using structured light for an automated electronics assembling robot is accelerated for an image frame to be used for computation using the simplest experimental set, which consists of a single camera and projector. The experiments for the depth evaluation process required 31 ms to 32 ms, which were optimized for the robot vision system that equips a 30-frames-per-second camera.

  • Over the last five years, we have conducted research on risk assessment of domestically developed genetically modified (GM) crops and found a number of factors which could delay risk assessment process. In this review, we described such cases and discussed the problem of transgene cassette integration, the lack of information on vectors, the poor quality control in seed production and absence of bioinformatic analysis on amino acid sequence homology before GM crop development. To solve these problems, we have suggested the introduction of the screening system of elite event before risk assessment process and quality control strategies for GM seed production. In addition, we suggested that the developers of GM crops should understand the importance of risk assessment and management for the commercialization of those crops and consider the biological and ecological characteristics of host plants. Consistent communications may need to be established between GM crop developers, risk assessors and risk managers at the initial stages of GM crop development to reduce trial-and-errors.

  • In this study, a risk-based cleanup approach using the leaching potential was suggested for the soil vapor extraction (SVE) process. A multi-component model was adopted with local equilibrium assumption (LEA), and Raoult's law was applied to estimate the leaching potential for BTEX. Finally, a risk analysis was conducted based on the leaching pontential calculated. To complete the feasibility of this approach, more investigations and discussions will be required in future.

  • 본 연구는 해양치유단지의 조성을 위한 입지평가에 대한 연구로서 평가항목 및 평가지표를 도출하고 평가방법을 제안하였다. 입지평가를 위한 평가항목과 평가지표를 정하기 위해 해양치유단지 해외사례를 조사하고 선행 유사사업의 입지평가사례를 분석하였다. 정부의 해양치유산업 관련 정책 및 지자체 사업계획 등을 고려하여 3개 대분류 평가항목, 8개 중분류 평가항목, 5개 소분류 평가항목, 26개 평가지표를 정하였으며 각 평가지표별 평가기준을 정하였다. 평가방법은 먼저 전문가로 구성된 평가위원회에서 평가항목별 가중치를 부여하고 다음으로 각 평가위원이 개별 평가지표에 대해 가중치와 점수를 부여하여 평가점수를 산정한다. 이 평가점수에 평가항목별 가중치를 곱하여 평가지표별 최종점수를 정하고 모든 평가지표의 최종점수들을 합하면 각 평가위원의 평가점수가 되며 평가위원들 평가점수를 산술평균하면 대상지 입지평가결과가 된다.

  • Software reliability in the software development process is an important issue. Software process improvement helps in finishing with reliable software product. In this field, SPC (Statistical process control) is a method of process management through application of statistical analysis, which involves and includes the defining, measuring, controlling, and improving of the processes. The proposed process involves evaluation of the parameter of the mean value function and hence the values of the mean value function at various inter failure times to develop relevant time control chart. In this paper, was proposed a control mechanism, based on time between failures observations using Rayleigh and Burr distribution property, which is based on Non Homogeneous Poisson Process (NHPP). In this study, the proposed model is reliable in terms of hazard function, because it is more efficient in this area can be used as an alternative to the existing model. Through this study, software developers are considered by the various intended functions, prior knowledge of the software to identify failure modes to feed to some extent shall be able to help.

  • 본 논문에서는 요트 계류장과 같은 소형 해상 부유체의 위기수준을 모니터링하기 위한 확률 기반 위기평가기법(Probability based risk Evaluation Techniques, PET)의 이론적인 접근 방법을 기술하였다. PET는 5단계 척도의 위기 기준을 이용한 위기 판단 절차가 핵심 개념이다. 이러한 5단계 척도들은 폐형 공식을 이용한 해상 부유체 운동의 응답함수에 대한 누적확률분포에서 계산했다. 그리고 위기기준을 갖는 PET의 위기판단 절차를 제안하였다. PET의 유용성 검증을 위하여 시뮬레이션 실험을 하였는데, 실험에는 해상 부유체의 운동 측정에 사용할 ADIS16405 센서의 전기특성을 갖는 모의 신호를 이용하였다. 실험결과, PET의 위기평가 오차는 최대 5.0 수준에서 0.38 수준으로 나타났다. 이 결과로부터 제안한 PET가 모니터링 기법으로 사용 가능함을 확인하였다.

  • This paper presents the HRTF based experimental approach to figure out why the human auditory perception on the interior noise source including the directional tonal components does not well match with the dominant features extracted from recorded acoustic signals in terms of psycho-acoustics. Since the general objective evaluation models for tonalness among various sound attributes are a function of width, frequency, excessive level of tonal components respectively, the directional tonal components cannot be properly evaluated without considering the effects of head-related transfer function on the binaural auditory perception. Thus, the directivity of source is additionally considered to prevent the erroneous conclusions from the same sound source in the process of source identification. The signal synthesis technique is used to solve a little difficulty in measuring all of desired acoustic signals for jury evaluation. The sound attributes of synthetic acoustics signals are analyzed to roughly predict the results of jury evaluation in advance by using sound quality factors such as loudness, sharpness, roughness, fluctuation strength and tonality. The jury evaluation is carefully conducted based on the recommended guideline suggested by N. Ottoet al. Each sound is respectively evaluated by selecting a value between -2 and 2 in intervals of 0.2 point. Through above procedure, based on the results of jury evaluation, it is confirmed that serious problems can be caused in the process of analyzing the dominant sound attributes in terms of psycho-acoustics according to the type of a microphone and a playback system.
