Our limited understanding of real-life music information queries is an impediment to developing music information retrieval (MIR) systems that meet the needs of real users. This study aims to contribute to developing a theorized understanding of how people seek music information by an empirical investigation of real-life queries, in particular, focusing on the accuracy of user-provided information and users' uncertainty expressions. This study found that much of users' information is inaccurate; users made various syntactic and semantic errors in providing this information. Despite these inaccuracies and uncertainties, many queries were successful in eliciting correct answers. A theory from pragmatics is suggested as a partial explanation for the unexpected success of inaccurate queries.

This paper defines the telepresence as a particular type of experience, rather than a collection of hardware. Defining telepresence in this way provides a means for examining telepresence in relation to other types of mediated experience. Presence refers to the natural perception of an environment, and telepresence refers to the mediated perception of an environment. Factors influencing whether a particular mediated environment will induce a sense of telepresence include the following: the combination of sensory stimuli employed in the environment, the ways in which participants are able to interact with the environment, and the characteristics of the individual experiencing the environment. Telepresence art invites the people from remote worlds to networked cyber space and creates the experience of 'being there' by making participants control the virtual reality system and receive feedback from their teleactions. It is the way to produce an open and engaging experience that manifests the cultural changes brought about by remote control, remote vision, telekinesis, and real-time exchange of audiovisual information. The principal determinants of telepresence are sensory immersion, sensory fidelity, cognitive fidelity and personal factors. This paper applies the 4 determinants to telepresence art works such as Ken Goldberg's Telegarden, Monika Fleischmann & Wolfgang Strauss' The Home of the Brain, Paul Sermon's Telematic Dreaming, Telematic Vision, Eduardo Kac's Uriapuru, Simon Penny's Traces and Paul Sermon & Andrea Zapp's A Body of Water.

The objective of the study is to identify the sub-path of entry into homelessness of young men and enhance understanding them. In specific, homeless risk factors were extracted through their experiences, and based on which the entry paths into homelessness were drawn. The homeless young adults were divided into two groups of those who became homeless in their adolescence and those who entered into homelessness after 19 and their differences were analyzed. As a results, the most prominent differences between the two sub-groups included individual and social factors; most of those who entered homelessness after 19 had physical or psychological problems, while the other group showed delinquency factors in adolescence and adulthood. As for social factors, the former group experienced more financial damage in the process of achieving independence before being homeless, while the latter group had relatively more experience of physical and psychological damage such as bullying, harassment and violence before being homeless and financial frauds. As for investigating the causality relationship of key homeless risk factors by adding a variable of time, and based on which, a constant pattern of entry paths toward homelessness was drawn among each sub-group of homeless young adults. For policy on homelessness, it is required to develop according to the characteristics of homeless young adults. Especially, a specific approach is necessary for the different homeless pathways by sub-group. Furthermore, the study indicated that management and preemptive responses for various homeless risk factors that homeless young adults experienced throughout their lifetime could be important prevention policy against homelessness.

This article focuses on reviewing place branding theories as a major toolkit of 'soft regional development'. Place branding provides sophisticate methodologies to strengthen city and regional image and identity. For effective place marketing practices, four of useful place branding tools are suggested. They include the methodology of place identity development, brand leadership system in local governance, construction of city brand architecture, and evaluation model for city brand equity. A process model is suggested for systematically organizing the diverse tools of place marketing and branding. The model is expected to be used as a framework of strategical soft regional development and planning. The place branding process model is to be an important theoretical and methodological basement of postmodern urban and regional development on which creativity, symbol and signs are more emphasized. More in-depth theoretical and empirical studies are needed. Geographical tradition and knowledge can play important roles in this inter-disciplinary process.

The purpose of this paper is to present a solution to the conflict when hydrogen energy is used for national energy transition through design thinking methodology. Research shows that design thinking enables joint design of policies for hydrogen energy transition between government and stakeholders. This is a macro approach based on empathy and cooperation, and can form consensus on the policy design process in the early stages. Starting with an understanding of hydrogen energy conflicts, ideas can be found based on the experiences gained from conflicts of stakeholders, disputes or lawsuits. And based on this, additional ideas on hydrogen energy transition will be verified the realization of the ideas. Collaboration with stakeholders to improve conflicts can create new values. In the process of reconfiguring the definition of energy transition problems, the opinions of stakeholders can be integrated with continuous empathy. Through design thinking methodology, we can integrate opinions of stakeholders and prevent conflicts.

It was found that Korean Standard of Estimate which has been used as the only basis of cost estimate of public construction projects had some side effects such as jerry-build construction and over-estimation because it failed to reflect the current price and the state-of-the-art construction methods in a changing construction environment. Therefore, the government decided to gradually introduce historical construction cost into cost estimate of public construction projects from 2004. This paper presents analytic criteria and a process model for deducing more current and reasonable historical construction cost for contract items from not only previous contract prices but also all of the other bid prices that were not contracted. The procedure of estimating actual unit cost proposed in this paper focuses on the removal of abnormal values including strategically too low or high prices and the time correction. In addition, basic research is conducted for the correction of actual unit cost through the analysis of fluctuation of bid price depending on bidding types and rates of successful bid. It is anticipated that the effective use of the proposed process model for estimating actual unit cost would make the cost estimation more current and reasonable.

Recently, Apartment Reconstruction Projects are performing only with the basis of profitability without establishing either certain criteria or standard guideline. In addition, the profitability information contained in a disposal plan tends to be considered as a fixed value, and it is frequently changeable because reconstruction projects have such a long time to complete and many participants with respective interests. As mentioned above, the new approach needs to be developed which covers the limitation of the unvaried one. Consequently, this study focuses on the probability approach considering not only variances that affect the profit, but the relationship between profit and risk, and then is modeling. This study is anticipated to improve the reliability and accuracy of expected value as well as apply to the decision making criteria quantitively about potentially hidden risks in that projects.

시뮬레이션(simulation)은 실 시스템(real system)의 효과적이고 효율적인 운영을 도모하기 위하여 실 시스템의 동작을 이해하고 분석, 예측, 평가하는 과학적인 문제해결 접근방법이다. 시뮬레이션 수행단계는 실 시스템의 행위를 정확히 반영하도록 타당한 모델을 구축하는 모델링 단계와 모델에 의도하는 명령어들을 컴퓨터 프로그램으로 작성하는 구현단계로 나누어진다. 시뮬레이션 모델은 시간, 상태, 확률변수, 상호규칙 등의 여러 관점에 따라 다양하게 존재하는데, DEVS(Descrete EVent system Specification) 모델은 연속적인 시간상에서 이산적으로 발생하는 사건에 따라 시스템의 상태를 분석할 수 있고 모델링 및 시뮬레이션 방법론의 형식화를 위한 견고한 이론적 기반을 제공하고 있다. 또한, DEVS 모델은 모듈적, 계층적 특성을 제공하고 집합론에 근거한 수학적 형식구조를 제공하여 실 시스템에 대한 체계적인 분석과정을 수행하게 되어 보다 현실적인 모델링을 가능하게 한다. 그러나 타당하지 못한 DEVS 모델이 구축되면 시뮬레이션을 통한 분석결과의 신뢰성이 떨어져 아무런 효과가 없고 경제적인 손실만이 따른다. DEVS 모델에 대한 기존의 타당성 검사가 많은 시간과 노력이 요구되고, 반복적인 DEVS 모델링 과정으로 인한 전문적이고 경험적인 지식을 요구한다. 또한, 모델설계자에 의해 설정된 실험 프레임하에서 DEVS 모델의 구성요소에 속하는 상태전이함수, 시간진행함수 및 출력함수에 대하여 commutative 성질의 보전성 검사가 어렵다는 문제점을 가지고 있다. 본 연구에서는 이와 같은 문제점을 해결하기 위하여, DEVS 모델에 대한 타당성 검사를 SPN(Stochastic Petri Net) 모델로 변환하여 SPN 모델을 이용하는 간단하고 효과적인 타당성 검사 방법을 제안한다. 먼저, DEVs 모델에 대한 개념과 기존의 DEVS 모델에 대한 타당성 검사 방법을 고찰하고 그 문제점에 대하여 자세히 설명한다. DEVS 모델의 타당성 검사에 이용하는 SPN 모델에 대한 개념과 DEVS 모델과 행위적으로 동등한 SNP 모델로 변환을 위한 관점을 제조명하다. 동일한 관점에서 두 모델의 상태표현이 같도록 DEVS 모델이 SPN 모델로 표현됨을 보이는 변환이론을 제시하고 변환이론을 바탕으로 모델 변환과정을 제시한다. 모델 변환이론과 변환고정을 기본으로 타당성 검사를 위한 새로운 동질함수(homogeneous function)를 정의하고 이와 함께 SPN 모델의 특성을 이용하여 DEVS 모델에 대한 타당성 검사 방법을 새롭게 제안한다.

In 2012, the International Council on Archives(ICA) distributed AtoM public release, an archival description software based on web, for free to support small archival institutions. The purpose of AtoM project was to let a single or multiple repositories describe archival materials based on ICA descriptive standards and access via a web browser. The value of AtoM project is to promote actual business experience by sharing technical expertise and form active community between users and developers. Recently, there is a growing interest in open source software in the field of domestic record management. This interest is to not only reduce cost, but to escape technology dependencies and to address requirements on the field. The critical mind of this study lies in the fact that there is no practical methodology to establish AtoM system. Even when using AtoM itself, basic tasks such as the migration of the existing data or the improvement of user interface are required. That is why this study suggests the process and methodologies to establish and customize archival information system based on AtoM software.
