Database schema integration is a significant issue in information systems. Because schema integration is a time-consuming and labor-intensive task, many studies have attempted to automate it. Researchers typically use XML as the source schema and leave much of the work to be done through DBA intervention, e.g., there are various naming conflicts related to relationship names in schema integration. In the past, the DBA had to intervene to resolve the naming-conflict name. In this paper, we introduce an algorithm that automatically generates relationship names to resolve relationship name conflicts that occur during schema integration. This algorithm is based on an Internet collocation and English sentence example dictionary. The relationship between the two entities is generated by analyzing examples extracted based on dictionary data through natural language processing. By building a semi-automated schema integration system and testing this algorithm, we found that it showed about 90% accuracy. Using this algorithm, we can resolve the problems related to naming conflicts that occur at schema integration automatically without DBA intervention.

To reduce maritime accidents and improve safety for domestic ships, the government has developed and is operating the Korean e-Navigation Service. The ship collision and grounding monitoring service and the route planning service were developed based on the experience of captains and navigators who navigated large ships. However, in Korea, small ships account for a large portion of the users of these services, so there are various difficulties and additional requirements for applying services based on large ships to small ships. To improve this, a data science-based algorithm model using maritime digital traffic information is being developed for small ships, and it is important to evaluate the performance of the developed model and compare its accuracy with existing services. In this study, we propose a performance evaluation method for the developed algorithm model and study how to compare and evaluate its accuracy with existing e-navigation services.

The increament of crustal thickness, continental growth and evolution, plate tectonic movements, and mega-impacts of meteorites have been worldwidely studied in the subdivision of Precambrian. In many subdivision methods of Precambrian Eon and Eonthem, the division based on the principle of the Plate tctonic movement referred internationally, is as follows, $L^AT_EX$ The rationality of this subdivision and some problems in the currently adopted stratigraphic subdivision of Precambrian Eonthem will by commented, and the validity of English and Korean Geological terminology on the Precambrian stratigraphy of northeastern Asia will be discussed also.

연명의료결정법의 정식 명칭은 '호스피스 완화의료 및 임종 과정에 있는 환자의 연명의료 결정에 관한 법'이다. 이 법은 호스피스 완화의료에 대한 것과 환자의 연명의료 결정에 대한 것을 규정하고 있다. 특히, 후자의 연명의료결정에 관한 부분은 법제정 과정에서 법 종교 의료 윤리 등 다양한 분야에서 논박이 있었지만 2018년 2월 4일부터 시행되고 있다. 법학에서는 이 법이 생명이라는 법익과 관련되어 있어 형사법적, 민사법적으로 중요한 의미를 갖는다. 이 법이 탄생되기 위해 두 번의 변곡점이 있었다. 첫째, 1997년 '보라매병원 사건'에서 의사를 작위에 의한 살인방조죄로 판결한 사건 둘째, 2009년 '김 할머니' 사건에서 회생할 수 없을 경우 가족 등이 진술한 환자 의사에 따라 연명 의료를 중단할 수 있다는 대법원 판결이다. 연명의료결정법은 헌법상 생명권과 자기운명결정권이라는 기본권 충돌이 발생한다. 두 기본권이 서로 상충 할 때에는 어떠한 기본권을 우선해야 하는지가 실질적으로 문제되는데, 이익형량을 통한 규범의 조화로운 해석을 통해 해결해야 한다. 또한 이 법의 흠결과 문제점을 고찰하여 개정작업이 진행되어야 한다.

In the bill of [Act on Certified Detective and Certified Detective Business] (hereinafter referred to as the Certified Detective Act) proposed and represented by the member of National Assembly, Lee Wan-Yong in 2017, the legislative point of view showed that various incidents and accidents, including new crimes, are frequently increasing as society develops and becomes more complex, however, it is not possible to solve all the incidents and accidents with the investigation force of the state alone due to manpower and budget, and therefore, a certified detective or private investigator are required. According to the decision of the Constitutional Court in June 2018, Article 40 (4) of the Act on the Use and Protection of Credit Information is concerned with 'finding the location and contact information of a specific person or investigating privacy other than commerce relations such as financial transactions' are prohibited. It is for the purpose of preventing illegal acts in the process of investigation such as the location, contact information, and the privacy of a specific person and protecting the privacy and tranquility of personal privacy from misuse and abuse of the personal information etc. Such 'privacy investigation business' currently operates in the form of self-employment business, which becomes a social issue as some companies illegally collect and provide such privacy information by using illegal cameras or vehicle location trackers and also comes to be the objects of clampdown of the investigative agency. Considering this reality, because it is difficult to find a resolution to materialize the legislative purpose of the Act on the use and protection of credit information other than prohibiting 'investigation business including privacy etc' and it is possible to run a similar type of business as a detective business in the scope that the laws of credit research business, security service business, the position of the Constitutional Court is that 'the ban on the investigations of privacy etc' does not infringe the claimant's freedom to choose a job. In addition to this decision, the precedent positions of the Constitutional Court have been that, in principle, the legislative regulation of a particular occupation was a matter of legislative policy determined by the legislator's political, economic and social considerations, unless otherwise there were any special circumstances, and. the Constitutional Court also widely recognized the legislative formation rights of legislators in the qualifications system related to the freedom of a job. In this regard, this study examines the problems and improvement plans of the certified detective system, focusing on the certified detective bill recently under discussion, and tries to establish a legal basis for the certified detective and certified detective business, in order to cultivate and institutionalize the certified detective business, and to suggest methodologies to seek for the development of the businesses and protect the rights of the people.
