The purpose of this study is to reveal the quantitative dose-response relationship between the noise emitted in the platform of subway station and the public response. The noise measured in the platform of subway station was used for a jury test. In order to find the factors which influence annoyance response due to the platform noise, jurors were examined for the difference of the annoying response, interrelation of sound quality parameter and annoyance response. The platform noise level was 77.2$\sim$83.9 dBA and the most of passengers at the platform were highly annoyed. And screen door contributes to annoyance reduction of platform noise. The results from analyzing sound quality parameters shows that loudness and annoyance response have a high correlation coefficient.

Mining the microarray data accumulated in the public data repositories can save experimental cost and time and provide valuable biomedical information. Big data analysis pooling multiple data sets increases statistical power, improves the reliability of the results, and reduces the specific bias of the individual study. However, integrating several data sets from different studies is needed to deal with many problems. In this study, I limited the focus to the cross platform classification that the platform of a testing sample is different from the platform of a training set, and suggested a simple classification method based on rank. This method is compared with the diagonal linear discriminant analysis, k nearest neighbor method and support vector machine using the cross platform real example data sets of two cancers.

Purpose: This study investigated the legal issues and policies on accommodation sharing based on qualitative research and examined how OECD societies establish laws and regulations to legalize accommodation sharing and prevent adverse effects. The purpose of this study is to contribute to the understanding of the different laws and regulations at both the country and city levels and to help better manage accommodation sharing in our society. The ultimate goal of this study is to enhance citizen understanding of platform businesses to minimize unnecessary conflicts. Research design, data and methodology: This study conducted a qualitative research by exploring laws and regulations in OECD countries. This study performed comparative analysis of accommodation sharing business' legislation, legal definitions, and operational policies that citizens should necessarily understand for better usage. Results: Local ordinances and regulations developed differently based on the situations of local markets and communities, so they are established and improved at the city or country level. Conclusions: Each government should consider preparing better policy on accommodation sharing by considering how to secure the housing market for residents with better establishment of new platform businesses and relationships with citizens. This study suggests policy reactions to government as policymakers, guests, hosts, platforms, and communities.

데이터의 관점이 업무자원을 넘어 새로운 가치자원으로 진화하면서, 그 처리방식의 무게중심도 단순 카테이션(Cartesian) 방식에서 맥락(Context)식별 방식으로 빠르게 전환되고 있다. 이러한 추세에 따라 최근 정부도 공공데이터 개방을 통한 민간 활용 여건 조성에 나서고 있다. 이에 본 연구는 정보처리관점에서 조직원과 대중의 차이를 탐색 차원에서 규명하고, 이를 바탕으로 대중을 대상으로 하는 공공데이터 플랫폼 설계의 기본 방향과 주안점을 제시하고자 하였다. 본 연구는 그간 추상에 머물러 있던 '대중의 집단지성'에서 벗어나 '집단지성 생태계' 조성을 위한 실천적 대안 모색의 시발점이 될 것이며, 공공데이터 개방에 필수적인 빅데이터 기반 구축의 실천적 아이디어로 활용될 수 있을 것이다.

Platform screen doors (PSD) installed at 289 stations in Seoul metropolitan subway from November 2005 to December 2009, are expected to prevent death from a fall and improve air quality. In this study, we systematically surveyed changes in radon concentrations before and after PSD installation in Seoul metropolitan subway stations. By solid-state nuclear track detectors (SSNTD), the radon concentrations before and after the PSD installation were measured at 54 stations of 6 lines from 2 to 7 reported to have relatively high radon concentrations. Mean radon concentrations at platforms were decreased by approximately 56% from 121.7 Bq/$m^3$ to 54.0 Bq/$m^3$. Before PSD installation, mean radon concentrations were in the decreasing order for subway lines 7, 5, 6, 3, 4 and 2. On the other hand, after PSD installation the order was changed to 5, 6, 7, 3, 4 and 2. According to a radon map of Seoul metropolitan subway, the number of platforms where radon concentration over was 74 Bq/$m^3$ decreased from 38 to 12 after PSD installation.

Open Data is an essential resource for the data industry. 'Act On Promotion Of The Provision And Use Of Public Data', enacted on July 30, 2013, mandates public institutions to manage the quality of Open Data and provide it to the public. Via such a legislation, the legal basis for the public to Open Data is prepared. Furthermore, public institutions are prohibited from developing and providing open data services that are duplicated or similar to those of the private sector, and private start-ups using open data are supported. However, as the demand for Open Data gradually increases, the cases of refusal to provide or interruption of Open Data held by public institutions are also increasing. Accordingly, the 'Open Data Mediation Committee' is established and operated so that the right to use data can be rescued through a simple dispute mediation procedure rather than complicated administrative litigation. The main issues dealt with in dispute settlement so far are usually the rights of third parties, such as open data including personal information, private information such as trade secrets, and copyrights. Plus, non-open data cannot be provided without the consent of the information subject. Rather than processing non-open data into open data through de-identification processing, positive results can be expected if consent is provided through active rights processing of the personal information subject. Not only can the Public Mydata Service be used by the information subject, but Open Data applicants will also be able to secure higher quality Open Data, which will have a positive impact on fostering the private data industry. This study derives a plan to establish a rights processing platform to enhance the usability of Open Data, including private information such as personal information, trade secrets, and copyright, which have become an issue when providing Open Data since 2014. With that, the proposals in this study are expected to serve as a stepping stone to revitalize private start-ups through the use of wide Open Data and improve public convenience through Public MyData services of information subjects.

플랫폼 금융은 데이터 분석과 플랫폼을 이용한 매칭이라는 새로운 자금조달 방식을 제시함으로써 중소기업의 대안금융으로 부상하고 있다. 이 사업의 본질은 빅데이터를 이용한 위험평가와 투자자의 위험-수익 선호(risk-return preference)를 적절히 반영할 수 있는 위험분산 기술을 금융업에 적용한 것이다. 이로써 소상공인을 위한 소액금융, 중소기업의 운전자본(working capital) 조달을 위한 공급망 금융의 형태로 기존 금융의 대안으로 부상하고 있다. 한국의 플랫폼 금융은 이 같은 가능성에도 아직 유치 단계(infant stage)이며, 정책적 지원을 필요로 한다. 이는 다음과 같이 요약할 수 있다. "기관 및 공공 투자참여", 플랫폼 금융의 민간 자금유입(crowd-in)을 위한 정책금융의 씨앗자금(seed money) 공급, "수용적 규제체계", 영국의 샌드박스와 같이 새로운 사업에 대한 한시적 규제 유예, "데이터 개방 확대", 재량적인 데이터 공유의 허용, "대안투자 수단의 보급", 저금리시대의 대안투자 수단으로서 플랫폼 금융 육성.

Ministries of Education are integrating different Learning Management Systems (LMS) to enhance teaching and learning during the lockdown to avoid academic loss. The key factor for delivering a high-quality education through LMS platforms is teachers' acceptance and adoption of the platform. Madrasati platform (which means My school) was introduced by Saudi Arabian Ministry of education as the formal teaching and learning for distance education for public education levels. This study aims to examine the effectiveness, usability and adoption of "Madrasati" platform from teachers' perspectives in Saudi Arabia. "SUS, CSUQ" tests were used to test the usability of the new platform. Using quantitative research design, data were collected using questionnaire. 200 teachers were selected randomly answered the survey. Data was analysed descriptively and inferentially using SPSS (25). The results obtained indicate that the teachers are highly satisfied using Madrasati platform and technically it is well designed. Also, Madrasati has positive effect on teaching quality. Moreover, Madrasati has high usability in teaching. One of the key findings were that the quality of the information content in Madrasati has a strong effect on teachers' perception of the Madrasati usefulness that led to a positive attitude towards Madrasati. These findings would be useful to the ministry of education and institutions trying to integrate technology in their teaching and learning processes. Thus, this paper contributes towards more effective utilisation of the extensive functionalities that Madrasati have to offer, which will contribute toward the development of pedagogy in Saudi Arabia.

To secure national future competitiveness, the Korean government announced the 『National Ultra-High Performance Computing (HPC) Innovation Strategy (2021.5.28.)』 and set three innovation strategy goals throughout establishing an innovation ecosystem. This study presented a heterogenous data-based strategic support framework that allowed to understand both the current status of domestic & foreign R&D areas and domestic industrial economy areas in terms of strategic fields related to ultra-high performance computing, and the empirical research was conducted in the life science and public health area. The HPC innovation ecosystem platform based on the connection of heterogeneous data (domestic R&D project-technology-industry-overseas R&D project) presented in this study provided useful and essential information that allowed establishing a specific action plan for the national HPC innovation strategy and contributing to vitalizing the innovation ecosystem. Since the evidence-based policy assumes that a more reasonable consensus is reached through a non-biased decision- making process among stakeholders, the proposed platform may contribute to enhancing policy momentum by increasing legitimacy and trust of planning of the national HPC strategy.
