In the 4th Industrial Revolution, the healthcare industry is undergoing a paradigm shift from post-care and management systems based on diagnosis and treatment to disease prevention and management based on personal precision medicine. To optimize medical services for individual patients, an open ecosystem for the healthcare industry that allows the exchange and utilization of personal health records (PHRs) is required. However, under the current system of hospital-centered data management, it is difficult to implement the linking and sharing of PHRs in practice. To address this problem, in this study, we present the design and implementation of a patient-centered PHR platform using blockchain technology. This platform achieved transparency and reliability in information management by eliminating the risk of leakage and tampering/altering personal information, which could occur when using a PHR. In addition, the patient-consent system was applied to a PHR; thus, the patient acted as the user with ownership. The proposed blockchain-based PHR platform enables the integration of personal medical information with scattered distribution across multiple hospitals, and allows patients to freely use their health records in their daily lives and emergencies. The proposed platform is expected to serve as a stepping stone for patient-centered healthcare data management and utilization.

To support the expansion of the autonomous robot market, the establishment of evaluation standards of the robot performance are essential. In this paper, to venture the standardization of the performance evaluation of the autonomous robot, the authors take the autonomous cleaning robot(ACR) as the initial stepping stone. Recently, the ACR has been being developed and marketed actively in many countries including Korea and it believes to be the fore-runner among various types of autonomous robot products. Standards of the performance evaluation for the ACR could be easily modified and applied to other autonomous robots. This paper formulates and suggests a group of standards for the performance evaluation based on a evaluation platform for the ACR. The newly developed performance evaluation platform has been designed to include all the important aspects of living environments in reality. In the platform the performance of the ACR is measured in terms of mobility, cleaning performance, avoidance of obstruction(safety), and operation noise. A few commercially available ACR products are collected and tested in the evaluation platform and compared against the performance evaluation standards formulated.

Automated production system is composed of many complicated techniques and it become a very difficult task to control, monitor and diagnose this compound system. Moreover, it is required to develop an effective diagnosing technique and reduce the diagnosing time while operating the system in parallel under many faults occurring concurrently. This study develops a Modular Artificial Neural Network(MANN) which can perform a diagnosing function of multiple faults with the following steps: 1) Modularizing a complicated system into subsystems. 2) Formulating a hierarchical structure by dividing the subsystem into many detailed elements. 3) Planting an artificial neural network into hierarchical module. The system developed is implemented on workstation platform with $X-Windows^{(r)}$ which provides multi-process, multi-tasking and IPC facilities for visualization of transaction, by applying the software written in $ANSI-C^{(r)}$ together with $MOTIF^{(r)}$ on the fault diagnosis of PI feedback controller reactor. It can be used as a simple stepping stone towards a perfect multiple diagnosing system covering with various industrial applications, and further provides an economical approach to prevent a disastrous failure of huge complicated systems.

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.

산업혁명 이후 기계로 만든 공산품이 시장의 대부분을 차지하고 있지만, 최근에는 장인의 노력, 품질에 대한 믿음, 제품의 희소성, 제품을 사용함으로써 얻는 자부심 등을 이유로 많은 소비자들이 같은 범주의 공산품보다 더 비싼 가격을 주고 핸드메이드 제품을 구매하고 있다. Etsy.com은 세계 최대 온라인 핸드메이드 플랫폼으로 2015년 4월 기업공개에서 2조원이 넘는 자금을 조달하면서 온라인 핸드메이드 플랫폼의 잠재력을 증명하였다. 그러나 실제 온라인 플랫폼 환경에서 이루어진 지능형 서비스 관련 선행연구들을 살펴보면 대부분 공산품만을 대상으로 하고 있어, 핸드메이드 제품에 대한 학술적 접근이 충분히 이뤄지지 않고 있음을 알 수 있다. 이에, 본 연구에서는 신호 이론과 온라인 플랫폼에서의 구매자-판매자 관계 특성에 대한 선행연구를 바탕으로 온라인 핸드메이드 플랫폼에 적용 가능한 핵심 특성요인인 입점 상점 특성(명성, 규모)과 입점 상점 관계특성(정보공유, 관계기간)을 도출한 후, Etsy.com 웹사이트에서 웹 하베스팅 방법으로 수집된 데이터를 이용하여 실증 분석하였다. 분석 결과, 입점 상점 특성 가운데 명성과 규모, 그리고 입점 상점 관계특성 가운데 정보공유는 입점 상점의 총 판매량에 유의한 영향을 주는 것으로 확인되었다. 또한, 입점 상점 특성 중 명성, 그리고 입점 상점 관계특성 중 관계기간은 입점 상점의 가격 프리미엄에 유의한 영향을 주는 것으로 나타났다. 본 연구의 결과로 온라인 핸드메이드 플랫폼에서 지능형 서비스 도입 및 운영을 위한 효과적인 관리 기준을 제시하고, 나아가 입점 상점이 핸드메이드 제품에 대한 판매량 증진 및 가격 프리미엄 극대화를 위한 실질적 전략 마련에 도움이 될 수 있기를 기대한다.

첨성대의 본질에 관한 현재의 가장 보편적인 가설은 천문관측대설이다. 천문관측대설의 근거는 주장하는 학자들마다 약간씩 차이가 있지만, 가장 중요한 근거는 '첨성대'라는 이름이며, 이에 대한 타당한 비판은 지금까지 제기된 바가 없다. 본 연구는 '첨성대'에 내포된 의미를 밝히고, '첨성대'가 천문관측대설의 타당한 근거인지를 살펴보았다. 천문관련설은 '첨성대'를 주로 '첨+성+대'로 해석했다. '볼 첨(瞻)'자와 '별 성(星)'자와 '대 대(臺)'자의 조합인 '첨성대'는 '천문을 관측한 대'를 뜻한다고 주장해 왔다. 한편 종교관련설의 경우, '별 성'은 '하늘 천(天)'을 의미하며, 첨성대에서 바라 본 '하늘'은 불교의 천상세계인 도리천이었다고 주장해 왔다. 본 연구는 『삼국유사』(1289±) 이전의 중국 기록에서 '첨성'의 용례들을 살펴보았다. '첨성'에 내포된 의미는 매우 다양하게 드러났다. '첨성+대'는 서술의 맥락에 따라서 '천문을 관측한 대'를 뜻할 수도 있고, '도리천을 우러러 본 대'를 뜻할 수도 있었다. 또한 '첨성'이 힌두교, 유교, 불교, 천주교, 도교와 같은 다양한 종교적 배경으로 실행되었음을 알 수가 있었고, 불교의 '첨성'의 경우는 적어도 외도(外道)의 '첨성', 법도(法道)의 '첨성', 세속(世俗)의 '첨성'으로 나눠질 수가 있음을 알게 되었다. 서술의 맥락에 따라서 '첨성+대'에 내포된 의미는 상당히 달라질 수가 있는 것이다. 『삼국유사』에 서술된 첨성대의 본질은 선덕여왕의 도리천 장례를 위한 묘탑(廟塔)으로 드러났다. 선덕여왕의 도리천 장례와 문무왕대의 사천왕사 건립은 신종원(1996)의 견해대로 밀교 승려 안함(안홍)에 의해 예언되었고, 『삼국유사』가 인용한 『별기』는 안함(안홍)의 참서(예언서)로 드러났다. 선덕여왕릉과 첨성대의 배치가 동지일출선에 정확하게 맞춰져 있음은 첨성대가 선덕여왕 유혼의 도리천 상생 통로였기 때문으로 판단되었다. 첨성대는 도리천으로 통하는 삼도보계(三道寶階)와 같은 '천국의 계단'를 가진 불탑이었고, '첨성대'는 『삼국유사』 왕력편의 '점성대'와 마찬가지로 '도리천을 우러러 본 대'라는 의미로 파악되었다. '첨성대'라는 이름은 천문관측대설의 근거가 될 수 없으며, 오히려 천문관련설을 총체적으로 부정할 수 있는 하나의 중요한 근거로 새롭게 평가되어야 마땅할 것이다.
