As the domestic housing supply problem has been resolved, the apartment construction market has shifted to a consumer-oriented market that wants high quality, and in particular, expectations in the area of finishing quality have increased. Looking at the status of complaints regarding apartment housing defects supplied by Korea Land and Housing Corporation, tile-related complaints are the type occurring the most frequently. While the Ministry of Land, Infrastructure and Transport(MOLIT) is making an ongoing effort to reduce complaints related to defects, through approaches such as drafting amendments to 「Investigation of defects in apartment houses, calculation of repair costs, and standards for determining defects」, the provision of preventive measures has been insufficient. In addition, by reviewing studies, there has been insufficient research to construct a classification system after deriving the characteristics of each type using the qualitative knowledge of experts, various quantitative indicators, and suggesting measures for reduction according to the causes of each type. Therefore, this study will reflect qualitative indicators to use the AHP analysis that makes it easy to identify the relationship between defects by surveying construction experts. Then, by visualizing the weight of 'Possibility of recurrence after repair,' 'Degree of difficulty in repairing defects' and 'Fault frequency' using a radial graph, we will analyze the characteristics of each type of tile construction defect and establish measures for reduction according to the cause. This will improve the quality of the living environment and contribute to the establishment of a system for smooth defect management and reduction of defects in apartment tile construction.

The society shows rapid change throughout various fields in the 21 century. These changes are in progress in Korea as well and the private security field is not in exception. The private security system has socially effective function by providing services, which the police cannot provide to citizen. However, it cannot be treated rightly the possibility of violation of human right during the actual action. The qualified person at least should take private investigation service considering privatization of criminal justice and considering that the Private Investigation Act submitted to the Congress could not affect its investigation authority to the citizen currently. The purpose of this study is examination of the private investigation system in Korea and other country and is presentation of its improvement. The chapter 1 composed of introduction on chapter 1, concept and service in chapter 2, private security system in other countryin chapter 3, private security system in chapter 4, problems and its improvements in chapter5, and conclusion in chapter 6. It requires not only consideration of government but also consideration of citizen and effort of both sidesto successful settlement of private security system in Korea.

시장조사 전문기업인 엠브레인트렌드모니터(www.trendmonitor.co.kr)가 2009년에 실시한 한 설문조사결과에서 여름철 냉방기기 사용빈도는 평균 선풍기 76회, 에어컨 24회(총 100회 기준)로 사람들은 더위를 이겨내기 위해 에어컨 보다 선풍기를 많이 사용하는 것으로 나타났다. 선풍기를 보유한 가구는 한 가구당 평균 2.47대의 선풍기를 보유하고 있었으며 전기세부담이 적고 제품가격이 저렴할 뿐만 아니라 이동 및 설치의 간편함 등을 선풍기의 장점으로 꼽았다. 이처럼 국민냉방기기로 굴림하고 있는 선풍기를 보다 안전하고 효과적으로 사용할 수 있는 올바른 사용 및 관리방법을 알아보도록 하자.

지속적으로 발생하는 대형 해양사고에 대한 대처방안의 일환으로 진행된 국제해사기구에서의 조사 및 연구는 선박의 물리적 감항성 이외에 선박을 운영하는 인적자원의 과실에 주목하게 되었다. 이러한 인적과실에 대한 대처방안으로 1994년에 '1974년 SOLAS 협약'의 부속서로 '국제안전관리규약'이라고 하는 이른바 'ISM Code'를 채택하게 되었다. 우리나라는 1999년에 'ISM Code'를 구 해상교통안전법(현 해사안전법)에 관련 조항을 신설하여 시행하고 있다. 최근 개정된 해사안전법에서는 해운선사가 선박의 안전운항 및 해양환경보호를 위한 안전관리체제를 수립하고, 이를 이행하기 위한 사업장의 인적 구성원들이 갖추어야 할 요건에 대해서 규정하고 있다. 하지만 법률 이행당사자인 선박소유자 또는 안전관리대행업자 등은 조문내용을 해석함에 있어 명확하고 통일된 의견을 내지 못하고 있어 혼란을 야기하고 있다. 이 논문에서는 해사안전법상 안전관리책임자와 안전관리자의 자격기준 등에 관한 법률상의 문제점을 살펴보고, 이에 대한 개선방안을 제시하고자 한다.

Since 2007, the government has been actively working to enhance the quality of public buildings, as evidenced by initiatives like the "National Basic Architecture Plan" and, since 2014, the "Building Service Industry Promotion Act." Despite these efforts, educational facilities continue to experience more frequent defects compared to large-scale apartment constructions. This study aims to analyze the primary causes of crack formation in educational facilities, employing the 2×2 MATRIX and IPA techniques to develop efficient crack prediction models. The research includes a review of relevant literature and an analysis of data from the Office of Education spanning 2019 to 2021 to pinpoint significant defects. Subsequently, 15 factors related to crack defects were identified through surveys and expert consultations. The 2×2 Matrix analysis of these factors highlighted the challenges in work processes and the effectiveness of preventative measures for crack formation, focusing on key areas for improvement. The findings from this study are anticipated to significantly contribute to the prevention and management of structural cracks in educational facilities, ensuring their long-term integrity.

This study analyzed problems of operating performance bond for public works and derived some suggestions for improvement. The Contract Law for Government Owner requires to submit performance bond which guarantees performing the construction contractor pays back compensation money when the obligation is not executed. Currently, first bid eligibility for participation is exactly required for executing company of performance bond obligation, not considering volume, technical level, and special type of remaining works. In collaboration contract, if guarantee accident occurs, it is obliged for remaining collaboration contractors to be qualified to fulfill the whole contract. This study proposes following improvement plan to solve problems of current performance bone in public works. Firstly, qualification criteria must be deregulated exceptionally for selecting proper contractor, which executing performance bond obligation, considering progress and characteristics of remaining works. Secondly, In collaboration contract, the prerequisite of remaining contractors' should be deregulated as 'implementation requirement of the remaining works'from'implementation requirement of the whole work'. Finally, defect responsibility should be included in liabilities of performance bond by specifying that owner or guarantee agency bear them.

In managing shipping business, the concept of seaworthiness of the vessel has developed in accordance with the development of the shipping industry. However, despite of the development of the vessel's seaworthiness, marine accident has continuously occurred at sea. International Maritime Organization(IMO) has paid attention to the research and investigation of Human Error in shipping operations in addition to physical seaworthiness of the vessel. In 1994, IMO adopted the "International Management Code for the Safe Operation of Ships and for Pollution Prevention(ISM code)" of "SOLAS 1974" Annex, to take countermeasure against this human error. In 1999, Korea adopted the 'ISM Code' and then enacted the Maritime Safety Act (previously Maritime Traffic Safety Act). The Maritime Safety Act regulates necessary qualifications of the Human Resources of shipping companies for establishment and implementation of the safety management system. However, there has been a discrepancy between shipowners and ship management companies in interpreting the legislative texts, finally causing confusion. In this paper, I would like to examine the deficiencies in the regulation on the standard of qualifications of the Designated Person under the Maritime Safety Act and thereby suggest any possible improvements in it.
