The International Maritime Organization (IMO) explicitly stipulates the required performance of satellite based radio-navigation systems available for navigational purposes. Until 2019, the IMO had only recognized systems that could be serviced globally for satellite based radio-navigation. However, India's regional navigation satellite system has been approved recently, and other regional navigation satellite systems have also been made available for maritime navigation. Thus far, the IMO has approved the use of a total of five satellite navigation systems, such as the GPS, GLONASS, Galileo, BeiDou, and NavIC. In Korea, in addition to the four satellite based radio-navigation systems that are used excluding NavIC, Japan's regional navigation satellite system that has not yet been approved can be received. Japan has requested the IMO to recognize the QZSS as a WWRNS to formalize its use for ocean navigations. Given that the service coverage of the QZSS is not limited to Japanese territorial waters and also includes Korean waters, the suitability analysis of the QZSS for domestic navigation is important for maritime safety. This study aims to analyze the suitability of using the QZSS for domestic navigation. Accordingly, this work explores the status and plans of the QZSS as well as the performance required by the IMO for recognition as a WWRNS. The methods and environmental conditions examined in this work are described, and the analyzed results are presented in terms of positioning accuracy and availability.

Despite the diverse system development and improvement initiatives that have been created to improve the environments of child birth and nurturing, the birth rate in Korean society remains low. Some minor teenage single parents give birth and raise children. Teenage single parents are supported by the Single-Parent Family Support Act, but some of their needs are still not being addressed. As each single parent has different backgrounds and socioeconomic characteristics, an investigation is required for developing differentiated support in which they will be considered both parents and children. Therefore, this study identifies the unique problems encountered by teenage parents, focuses on single mothers giving birth, and explores measures that teenage parents can use to be independent members of civil society. Three suggestions are presented for the period from pregnancy and childbearing to parenting. First, there should be an education support plan that will enable them to finish tertiary education, and parent education. Second, measures should be created to initiate a change in direction in indifferent biological(real) fathers: these should enlighten and help them participate in rearing their children. Third, in addition to improvements of the current systems only targeting single parent-family support, which will help differentiate teenage parent support from adolescent single parent-family support, assistance should be given for teenage single parents to grow as a Subject of Rights through tailored independent support programs.

This paper examines discussions surrounding cognitive liberty, neuro-privacy, and mental integrity from the perspective of Neuro-rights. The right to control one's neurological data entails self-determination of collection and usage of one's data, and the right to object to any way such data may be employed to negatively impact oneself. As innovations in neurotechnologies bear benefits and downsides, a novel concept of the neuro-rights has been suggested to protect individual liberty and rights. In Oct. 2020, the Chilean Senate presented the 'Proyecto de ley sobre neuroderechos' to promote the recognition and protection of neuro-rights. This new bill defines all data obtained from the brain as neuronal data and outlaws the commerce of this data. Neurotechnology, especially when paired with big data and artificial intelligence, has the potential to turn one's neurological state into data. The possibility of inferring one's intent, preferences, personality, memory, emotions, and so on, poses harm to individual liberty and rights. However, the collection and use of neural data may outpace legislative innovation in the near future. Legal protection of neural data and the rights of its subject must be established in a comprehensive way, to adapt to the evolving data economy and technical environment.

본고는 중세도시연구의 관점에서 도성 헤이안쿄(平安京)가 중세 교토(京都)로 변화하는 계기와 그 의미, 그것이 새로운 무가(武家) 정권도시(政權都市)에 어떤 영향을 미쳤는지에 대하여 논하였다. 율령제 마지막 도성인 헤이안쿄는 천황을 절대적 정점으로 한 중앙집권이 동심원구조로 구현된 '왕성(王城)의 땅'이었으나, 10세기 후반 이후 도성의 구심점이었던 내리(內裏)가 헤이안큐(平安宮) 밖으로 나오는 등의 변화가 시작되었고, 도성의 이념과 틀이 급속하게 해체 변용되었다. 또 고대왕권을 대신하여 새로운 형태로 왕권과 여러 권력을 담당한 원(院)과 롱관가(瀧關家), 대두하는 무가권력 등이 그 본거지에 권력의 개성과 시대성을 반영한 새로운 경관과 공간원리를 생성하였다. 그것은 다음과 같은 공통점을 갖는다. (1) 큰 정토정원을 갖는 御堂(사찰)과 세트를 이룬 御所(천황의 거소). (2)황통(천황가 내의 계통)과 가족의 상징으로서 조상을 모신 분묘를 중심으로 한 도시형성. (3) 내리를 기점으로 남북으로 주축을 갖는 고대도성과 달리, 어당과 어소가 동서로 배열된 동서가로를 주축으로 한 도시계획. (4) 수도와 외부를 잇는 교통의 결절점에 입지하였고, 특히 하천변을 향해 적극적으로 확장된 도시. 일본 중세는 무가정권의 시대를 맞이하여 도고쿠(東國) 초기 무가정권의 본거지 히라이즈미(平泉)와 최초의 막부가 열린 가마쿠라(鎌倉)가 모델로 한 것은 '도성 헤이안큐'가 아니라 헤이안큐 수도 밖 신도시의 경관과 공간원리였다. 특히 히라이즈미와 가마쿠라 등이 가정기관(家政機關)과 조상의 묘를 중심으로 한 '가족 원리'에 따른 정권도시를 적극적으로 수용한 것은 단순한 도시의 모방이 아니라 주종관계를 축으로 의제적인 '집(家) 원리'로 권력이 형성된 무가에는 더욱 어울리는 논리이며, 또 고대와는 다른 새로운 시대의 논리였기 때문이다. 그 한편으로 무가의 대들보로서 무사들에 의해 추대된 초기 무가정권은 도시의 논리와 경관을 도입하였을 뿐 아니라 그들과 공통의 가치관을 표현하는 것도 중요한 요소였다. 그것이 최신의 도시를 모방한 어당과, 그것과는 대조적인 도고쿠 무가의 전통적인 어소의 병립이라는 종교공간과 정치 일상공간에서의 권위표상의 의식적인 분리에 의해 표현되었다. 히라이즈미와 가마쿠라에서는 유통, 상공업 등의 도시기능과 도시적인 경관이 정비되기까지 약 50년의 시간이 경과할 필요가 있었다. 12세기 일본의 무가정권은 스스로의 거점으로서 도시를 기획, 형성하는 의식과 실현하는 능력을 얼마나 가지고 있었는가 검토가 필요하다. 명확한 동아시아모델의 도성을 실현함으로써 왕권의 존재를 드러낸 고대 율령정권과의 차이점은 매우 크다. 이후 무가가 권력의 의도를 도시구조로서 명확하게 드러낸 것은 15세기 후반의 전국시대 다이묘(大名)의 죠카마치(城下町)로부터이다. 특히 16세기 후반부터 천하통일을 실현한 오다 노부나가, 도요토미 히데요시의 연합정권에서는 구체적인 성(城)과, 그 성을 중심으로 한 계층성을 명시한 죠카마치의 공간설계가 있었다. 여기서는 다시금 '도시의 경관'이 명확한 권력의 상징으로서 기능하게 된 것이다.

Although social big data can provide a multi-faceted perspective on school bullying experiences among children and adolescents, the complexity and variety of unstructured text presents a challenge for systematic collection and analysis of the data. Development of an ontology, which identifies key terms and their intricate relationships, is crucial for extracting key concepts and effectively collecting data. The current study elaborated on the definition of an ontology, carefully described the 7 stage development process, and applied the ontology for collecting and analyzing school bullying social big data. As a result, approximately 2,400 key terms were extracted in top-, middle-, and lower-level categories, concerning domains of participants, causes, types, location, region, and intervention. The study contributes to the literature by explaining the ontology development process and proposing a novel alternative research model that uses social big data in school bullying research. Findings from this ontology study may provide a basis for social big data research. Practical implications of this study lie in not only helping to understand the experience of school bullying participants, but also in offering a macro perspective on school bullying as a social phenomenon.

The Public Records and Archives Management Law was enacted on June 24, 2009 and was in effect in April 1, 2011. This Act is different from existing Public Archives Law and National Archives Law. Before enacting Public Records and Archives Management Law, Public Archives Law and Information Disclosure Law was the backbone of Japanese Public Records management system. Public Archives Law is composed of management and access for non-active records in Public Archives. Information Disclosure Law is prescribed management of active-records in administrative agency. Public Records and Archives Management Law is the first comprehensive law of managing administrative records including historical records (nonactive-records). The law is prescribed that the public records and archives are intellectual resources shared by citizens and allows people to have more access to them. The law states that public records is basis of democracy and accountability for current and future generation. This article analyzed the relationship of law and its implementing ordinance and Guideline of administrative public records management, and analyzed the law and record-schedule. Furthermore, this article examined significance of the law and democracy, administration's transparency. In accordance with enacting the law, Japanese Public Records Management System will develop. and we must pay close attention to that situation.

Legislative stability of the production and management of electronic records and the enhancement of infrastructure have reached significant levels through relentless efforts of academic and public institutions in the field. In addition, appraisal and disposal of records also have to be done by retention periods, business functions, administrational and historical values, and certain procedures. The law specifies that public institutions must assign record managers. The underlying reason is for record managers to arbitrate the review process when records are to be evaluated and discarded and to prevent unauthorized disuses. It is also for just evaluations with the professionalism. Evaluation and discard of records have significant meanings in record management. Thus, these processes need to be handled properly in the standard record management system. Evaluation should be proceeded by the law enacted under the task functional and social agreement. Since, the record discard is decided through the technical and logical process, the support for evaluation and discard works are important above all things. In this paper, I deducted functional requirements of standard record management system by analyzing methods including the analysis of legislation and standard related to electronic records and the examination of the user's manual of record management system. I researched through the interviews of the record managers in public institutions. Based on this research, I deducted the implications for the evaluation of standard record management system and the estimation of functional requirements for discard. I also discussed future directions of improvements and follow-up studies.

In the era of the 4-th industrial revolution, the concept of smart factory is emerging. There are efforts to predict the occurrences of facility errors which have negative effects on the utilization and productivity by using data analysis. Data composed of the situation of a facility error and the type of the error, called the facility error log, is required for the prediction. However, in many manufacturing companies, the types of facility error are not precisely defined and categorized. The worker who operates the facilities writes the type of facility error in the form with unstructured text based on his or her empirical judgement. That makes it impossible to analyze data. Therefore, this paper proposes a framework for constructing a phrase network to support the identification and classification of facility error types by using facility error logs written by operators. Specifically, phrase indicating the types are extracted from text data by using dictionary which classifies terms by their usage. Then, a phrase network is constructed by calculating the similarity between the extracted phrase. The performance of the proposed method was evaluated by using real-world facility error logs. It is expected that the proposed method will contribute to the accurate identification of error types and to the prediction of facility errors.

Many companies are executing big data analysis and utilization projects to legitimize the development of new business areas or conversion of management or technical strategies. In Korea and abroad, however, such projects are failing because they are not completed within specified deadlines, which is not unrelated to the current situation in which the knowledge base for big data project risk management from an engineering perspective is grossly lacking. As such, the current study analyzes the risk factors of big data implementation and utilization projects, in addition to finding risk factors that are highly important. To achieve this end, the study extracts project risk factors via literature review, after which they are grouped using affinity methodology and sifted through expert surveys. The deduced risk factors are structuralize using factor analysis to develop a table that categorizes various types of big data project risk factors. The current study is significant that in it provides a basis for developing basic control indicators related to risk identification, risk assessment, and risk analysis. The findings from the study contribute greatly to the success of big data projects, by providing theoretical basis regarding efficient big data project risk management.

With the advancement of information and communications technology, a means to recruit IT professional has fundamentally changed. Nowadays recruiters search for candidate information from the Web as well as traditional information sources such as résumés or interviews. Particularly, open-source software development (OSSD) platforms have become an opportunity for developers to demonstrate their IT capabilities, making it a way for recruiters to find the right candidates, whom they need. Therefore, this study aims to investigate the impact developers' profiles in an OSSD platform on their finding a job. This study examined four antecedents of developer information that can accelerate their job search: job-seeking status, personal-information posting, learning activities and knowledge contribution activities. For the empirical analysis, we developed a Web crawler and gathered a dataset on 4,005 developers from GitHub, which is a well-known OSSD platform. Proportional hazards regression was used for data analysis because shorter job-seeking period implies more successful result of job change. Our results indicate that developers, who explicitly posted their job-seeking status, had shorter job-seeking periods than those who did not. The other antecedents (i.e., personal-information posting, learning, and knowledge contribution activities) also contributed in reducing the job-seeking period. These findings imply values of OSSD platforms for recruiters to find proper candidates and for developers to successfully find a job.
