  • 본 연구에서는 공단에서 발생하는 악취물질을 냄새센서를 이용하여 상시 감시하는 것을 목적으로 한다. 현재 다종다양한 냄새를 측정하기 위한 악취평가 방법으로는 관능측정법이 이용되고 있다. 그러나 이 방법은 악취판정원의 냄새세기의 차이와 판정원(panel)의 생체리듬에 따른 차이로 인하여 냄새의 객관적인 평가에 무리가 따르며, 언제, 어디서 돌발적으로 발생하는 악취의 연속적인 감시에 문제점을 나타내고 있다. 더욱이 우리나라는 환경 악취에 대해 직접관능측정법에 의한 악취 측정이 실시 되고 있어서 객관적으로 악취평가를 하기가 매우 곤란하다.

  • Recently, as tunnel structures are getting older and decrepit, many tunnel inspections are carried out for evaluating the tunnel state and safety. But, because there is no exact standard for tunnel state and safety, depending on subjective decision, the new standard to assess the tunnel state is required. The existing standard including mainly the assessment of the state of tunnel lining is not considered the characteristics of tunnel as underground structures. Also, the item of assessment and process of grading and classifying the state of tunnel is not objective and systemetic. In this study, new standard for assessment of tunnel state is presented for improving the problems in evaluating the tunnel state and safety. In the new standard, the new items of assessment including geotechnical condition were selected and graded, the process in classifying the tunnel state is quantitative for objective assessment for tunnel state. This new standard and method is practically used in effective safety inspection and diagnosis and tunnel maintenance.

  • Three degrees of freedom plus(3DoF+) and six degrees of freedom(6DoF) system, which supports a user's movements in graphical and natural scene-based virtual reality, requires multiple high-quality and high-resolution videos to provide immersive media. Previous video quality assessment methods are not appropriate for the 3DoF+ and 6DoF system assessment because different types of artifacts occur in these systems which are not shown in the traditional video compression. This paper provides the performance assessments of several quality assessment methods in 3DoF+ system. Furthermore, this paper presents a super metric, which combines multiple quality assessment methods, thereby it showed a higher correlation coefficient with the subjective quality assessment than the previous methods. Experimental results on 3DoF+ immersive video showed 0.4513 gain on correlation coefficient with subjective quality assessment compared to that of peak signal-to-noise ratio(PSNR).

  • As transaction and investment using technology are vitalized, the need for objective standards for the technology is increasing. Current technology value evaluation system is limited lacking reliability and objectivity. Besides the traditional evaluation methodology which are market approach, income approach and cost approach other diverse evaluation methodology such as real option method and royalty calculation method are being studied; however currently there are no dominant evaluation methodology in the market. Same value evaluation system cannot be applied between similar technologies because value of technology is relatively decided based on the target. Approaching through collective intelligence and crowd sourcing, in meaning of majority participant's decision can make objective and better result than handful of experts, suggest alternative to problems of such matter above. By grafting the four types of crowd sourcing model which are Wisdom, Voting, Funding and Creation, this paper will discuss the ways to enhance the objectivity of technology evaluation through direct evaluation utilizing expert group and the public's indirect evaluation.

  • To prepare the objective quality control index of red pepper powder, the relationships among the color appearance, capsanthin red pigment and the contamination of coliform bacteria were studied and summarized as followings; 1. Visual method by human eyes was inadequate to grade the quality of red pepper powder, because of the different personal color evaluation. 2. Grading upon capsanthin contents are well agreed with the color appearance of the red pepper powder. Therefore, color appearance can be correlated with the capsanthin content. 3. Color appearance of the red pepper can be numerically expressed with Hunter-value a/b; Capsanthin $content(mg/g-red pepper)=0.257{\times}10^{0.703}(a/b)$ and it can be used as an index of the quality control of red pepper powder. 4. There was no distinct correlation between the comtamination of coliform bacteria and the color value.

  • Skin condition is an important concern in beauty aspect. This study considered a rough skin condition analysis method that beauty industry workers can do through visual observation or skin condition images taken with smartphones. First, studies that combine subjective and objective evaluations were selected among degree papers and academic papers searched by keywords related to 'skin condition' in the Research Information Sharing Service(RISS). Among them, papers that derive correlations with visually verifiable factors were selected. Next, the relationship between factors that match subjective skin condition and objective skin measurement results and factors that can be visually identified on the skin surface was investigated. According to the study, the most suitable factor for matching subjective and objective evaluations was 'oil volume', which is significantly related to 'pore', 'skin texture' and 'erythema', which can be visually checked on the skin surface. It is believed that a rough skin condition analysis will be possible using this.

  • This paper propose color assessment method using HSI model to evaluate quantitative quality of mosaic images by aerial digital frame camera. Firstly, we convert RGB color into HSI model and we extract six pixel information of S and I corresponding to H from adjacency image by using HSI model. Secondly, a method to measure similarity and contrast is proposed and performed for assesment of observation regarding adjacency images. Through these procedure, we could generate four parameters. We could observe that both of the evaluation results by proposed method and the evaluation results by visual were almost similar. This facts support that our method based on several formula can be an objective method to evaluate a quality of mosaic images itself.

  • As a result of the compulsory of information system audit and a rise in audit demand, the quality improvement of information system audit is being emphasized. However, since the current information system audit heavily depends on the auditor's experience, skill, and subjective judgments, it incurs distrust in the objectivity and reliability of audit results from audit interest person. Furthermore, so far research activities aimed at securing the objectivity and reliability of audits have not been adequately carried out. Therefore, this paper presents a quantitative method for information system audit evaluation in order to contribute to the quality improvement of overall information system audit through securing compliance, objectivity, and reliability of information system audit. The quantitative method is largely composed of two sectors, such as evaluation areas and items, scores calculation for evaluation items, and can generally apply the information system audit standard to information system audit evaluation.
