This study deals with the changes in the government-funded research institutes (GRI) in terms of 'responding to social challenges and turning to the institutes that are pursuing sustainability transition'. The newly established societal problem-solving R&D projects in GRIs are core experiments for the transition. In order to discuss about the prospect of transition of GRIs, this study used focus group interview approach. In the interview, the GRIs's stance on the societal problem-solving R&D projects, and its process, problems and the policy direction had been discussed. It is suggested that the necessity of transition is discussed and transition experiments are proceeding on a small scale, but experiments are still underway in the existing framework. In order to facilitate the transition in GRIs, it is necessary to carry out the experiment and the vision making work from the inside the GRI.

In an ordinary CT scan, a large number of projections with full field-of-view (FFOV) are necessary to reconstruct high resolution images. However, excessive x-ray dosage is a great concern in FFOV scan. Region-of-interest (ROI) CT or sparse-view CT is considered to be a solution to reduce x-ray dosage in CT scanning, but it suffers from bright-band artifacts or streak artifacts giving contrast anomaly in the reconstructed image. In this study, we propose an image reconstruction method to eliminate the bright-band artifacts and the streak artifacts simultaneously. In addition to the ROI scan for the interior projection data with relatively high sampling rate in the view direction, we get sparse-view exterior projection data with much lower sampling rate. Then, we reconstruct images by solving a constrained total variation (TV) minimization problem for the interior projection data, which is assisted by the exterior projection data in the compressed sensing (CS) framework. For the interior image reconstruction assisted by the exterior projection data, we implemented the proposed method which enforces dual data fidelity terms and a TV term. The proposed method has effectively suppressed the bright-band artifacts around the ROI boundary and the streak artifacts in the ROI image. We expect the proposed method can be used for low-dose CT scans based on limited x-ray exposure to a small ROI in the human body.

Computed tomography (CT) is one of the most widely used medical imaging modality. However, substantial x-ray dose exposed to the human subject during the CT scan is a great concern. Region-of-interest (ROI) CT is considered to be a possible solution for its potential to reduce the x-ray dose to the human subject. In most of ROI-CT scans, the ROI is set to a circular shape whose diameter is often considerably smaller than the full field-of-view (FOV). However, an arbitrarily shaped ROI is very desirable to reduce the x-ray dose more than the circularly shaped ROI can do. We propose a new method to make a non-circular convex-shaped ROI along with the image reconstruction method. To make a ROI with an arbitrary convex shape, dynamic collimations are necessary to minimize the x-ray dose at each angle of view. In addition to the dynamic collimation, we get the ROI projection data with slightly lower sampling rate in the view direction to further reduce the x-ray dose. We reconstruct images from the ROI projection data in the compressed sensing (CS) framework assisted by the exterior projection data acquired from the pilot scan to set the ROI. To validate the proposed method, we used the experimental micro-CT projection data after truncating them to simulate the dynamic collimation. The reconstructed ROI images showed little errors as compared to the images reconstructed from the full-FOV scan data as well as little artifacts inside the ROI. We expect the proposed method can significantly reduce the x-ray dose in CT scans if the dynamic collimation is realized in real CT machines.

The purpose of this study was to perform a content analysis on 62 domestic and international journals from 1998 to 2017, in order to review research trends in music and people with visual impairments. The framework of the content analysis was based on the year of publication, field of journal, research method, type of research, research subject, participants' age, and factors of impairment. The results showed that both domestic and international journals have rapidly increased in the last 10 years, and have expanded into the fields of education and therapy. In the research method, survey research was conducted much more frequently in domestic journals, while both qualitative and experimental research were employed on a roughly even basis in international journals. With respect to the type and subject of research, music perception and recent trends on the subject of musical interest and aptitude took up the majority of domestic journals, while international journals focused on music intervention, music perception and cognition with musical influences and experiences. The participants in both domestic and international journals were children, adolescents and adults, while the elderly were not observed. In the factors of impairment, research on people with total blindness or low vision were conducted frequently, but those with adventitious vision loss or multiple impairments were rarely performed. This study could be meaningful to suggest the direction of further studies, through the investigation of research trends in music and people with visual impairments.

It has lately been recognized that the sharing and exchanging of the research results information is the critical factor to improve the research productivity. So many institutions are planning or developing the information systems which provide the research information services for researcher. But it has very difficulty in integrating the research resources information due to the dispersion and heterogeneity in data sources, and semantic and structural difference in describing data. We propose the semantic web based methodology and conceptual framework for raising the interoperability of metadata about research results information, which will support the integration of the distributed research data for information services in the end. We first introduce the ontology which is developed based on Standard Metadata of Research Results Information published by STISC. Then to show the applicability in real-world environment, we express the metadata of research information in RDF/RDFS according to ontology. Finally we proposed the conceptual architecture of research information service system which shows the main components, the functional requirements, and the principal and design direction at implementing the system.

This paper attempts to explore the universal foundation on which the discourses on the validity criteria in qualitative research should be based, and further discuss in depth the scope and direction of an adequate validity criterion in qualitative research by critical examination of previous discourses. To establish the foundation for qualitative research, first of all, the concept of quality and qualitative paradigm were examined in terms of ontology and epistemology, especially focused on the works carried out by Aristotle, Kenneth and Boyd. Secondly, the earlier studies on the validity of qualitative research were critically reviewed in terms of the theoretical findings on the concept of quality and qualitative paradigm. The major results include the following: First, the true content of quality is defined as the 'what-ness' or essence of things perceived by subjects, and qualitative paradigm as adequate framework for qualitative research is comprised of two intrinsic modes: one is the mode of awareness and the other is that of expression. Second, qualitative researchers are able to reach to the higher level of validity by considering not only the subjectivity and the originality but also the sociality in drawing a conclusion through qualitative perception. Third, the trend of previous validity discourses can be firmly summarized as the effort to overcome the effect of quantitative research and acquire the true identity for qualitative research, which is subjectivity, and as the quest to compromise the tension between subjectivity and sociality. Finally, based on the findings, several research topics are suggested. For example, the more attention should be paid to the area of the expression of qualitative awareness as a way of overcome the tension between subjectivity and publicness.

The purpose of this study is to illuminate the location of fashion in contemporary society and to suggest a direction for fashion criticism in aesthetic$\hat{u}$cultural perspective. For this, literature researches about some of art criticism and fashion criticism theories and cultural studies related to fashion are performed. In this study, fashion criticism is defined as a linguistic analysis and interpretation about a variety of discursive networks around fashion as well as an aesthetic analysis of it. Considering this definition, an analytical framework for the contemporary fashion criticism combines Feldman's and Carney's models with Crane & Bovone's and Entwistle's sociological studies for aesthetic and cultural perspectives. At first, its aesthetic perspective shows 'Description'-'Descriptive formative features', 'Analysis'-'Locate the style' and 'Aesthetic value', 'Interpretation'- 'Interpretation of the fashion object' and 'Socio-cultural interpretation', 'Judgment'-'Critical judgment'. Then, its cultural perspective especially emphasizes 'Socio-cultural interpretation' of the 6 steps above. Socio-cultural interpretation gets tangled with the network of various cultural agents within the fashion system, producers/designers, retailers/suppliers, media/editors, consumers/spectators, and so on. In the course of the fashion system 5 analytical methods about the fashion object can be suggested and they are as follows: Analyses of texts, discourses and symbols of a fashion object, Analyses of fashion systems which produces symbolic values, Analyses of the communication of symbolic values and the disseminating processes through the media, Analyses of the attribution of symbolic values to a fashion object by consumers, and Cross-national studies of symbolic values expressed in a fashion object.

The primary objective of the agency research in the game theory lives in the maintenance of Pareto is optimal condition for the optimal incentive contract. The basic concepts which are related to this objective are reviewed in connection with the general assumptions to model it, the moral hazard and adverse selection which arised from the information asymmetry, and finally the problem of risk distribution. The demand for auditing and the role of auditor have been addressed by ASOBAC. Issues which an auditor is explicitly introduced in a principal-agent framework have been addressed in this paper. These issues must be confronted to appropriately with the auditor, and to achieve an adequate understanding of optimal confronting arrangement with the auditor. The first step in introducing an auditor into this analysis is to examine the game-theoretic foundation of such a expended agency model. The Mathematical program formulated may not yield solution that are resonable. This arises because the program may call for the auditor and manager to play dominated Nash equilibra in some subgame. The nontrivial natures of the subgame implies that randomized strategies by the auditor and manager nay be of crucial importance. The possibilities for overcoming the randomized strategy problem were suggested; change the rule of the game and or impose covexity condition. The former seems unjustifiable in on auditing context, and the latter promising but difficult to achieve. The discussion ended with an extension of the revelation principle to the owner manager-auditor game, assuming strategies. An examination of the restriction and improvement direction of the basic concept of agency theory was addressed in the later part of this paper. Many important aspects of auditor incentives are inherently multiple-agent, multiple-period, multiple-objectine, phenomena and require further analyses and researches.
