The purpose of this study is to understand the concept of zero-waste design and to apply Sophia Vyzoviti's folding techniques to develop a zero-waste fashion design method that contributes to sustainable fashion design. In this study, we explore the method and characteristics of zero-waste fashion design based on the concept of folding described in Sophia Vyzoviti's book on folding techniques. Using the autonomy of Sophia Vyzoviti's folding technique, four changeable folding fashion designs were developed and produced, demonstrating zero-waste fashion design. The results were as follows. First, the development of fashion designs using Sophia Vyzoviti's folding techniques enabled the development and production of free and creative zero-waste fashion designs that were three-dimensional, continuous, fluid, and full of potential. Second, the production of zero-waste patterns was further developed into a transformable fashion design that can be used with geometric patterns. These folding techniques produced a fashion design method that could transform one piece of clothing, demonstration the potential for maintenance of creativity using a zero-waste design based on these folding techniques. Third, the double-faced fabric, Neoprene, was chosen as an appropriate material as it emphasizes the depth of folding with application of two colors and its cotton/polyester blend that is suitable for folding.

The purpose of this research is to improve sustainable clothes care by comparing household washer's standard course and quick course. Detergency at each course was classified by laundry weight, detergent concentration, and soils. Also, fabric damage from each course was compared. Washing experiments were carried out using two types of washing machines and three types of detergents. Using the standard soiled fabrics of EMPA 108 set, detergency was compared by laundry weight, soil, and detergent concentration. Additionally, fabric damage was evaluated using the mechanical action of MA-40. The results of the research were as follows. First, a standard course, having more working time exhibited better detergency than a quick course. However, the detergency deviation under 6kg laundry weight was as low as 9.0%. Second, detergency by the type of soil was more effective in standard course than in a quick course, but hydrophilic protein soils had a small detergency deviation at 7.6%. Moreover, hydrophobic oil, complex, and particulate soils had a higher deviation at 19.7% Third, fabric damage was in proportion to operating time. Fourth, a quick course showed approximately 80% detergency regardless of the type of detergent. in the case of using 50% of the recommended allowance by the detergent manufacturer. In conclusion, reducing the operating washing time and detergent concentration is in accordance with increasing sustainability, in the case of washing with lightly soiled fabrics under 6kg of laundry weight.

The purpose of this study was to explore how the college students of the beauty department changed their perspective about jobs, career development, and self-reflection in the process of job shadowing. We selected 8 students who were enrolled in the beauty department of a college located in the capital area and conducted individual in-depth interviews with them. According to the result of the study, First, participants have learned attitude, knowledge, competence, and an important matter necessary to achieve a excellent performance in the beauty job. In particular, they figured out that a core competency for a successful beauty job is to share a social relationship with the clients. Second, they recognized that doing a beauty job is very tough and then set a criteria to make a decision of their future job. Doing a Job shadowing made them being change in the area of job and their job perspective. Finally, they looked themselves back how they are satisfying with developing their career at the beauty department. This study is significantly meaningful in that it contextually showed how the college students are developing their job careers through an indirect job experience from a constructive point of view. Moreover, this study is different from the existing studies focusing on student's direct work experiences such as the existing internship programs, which focused on exploring the student's indirect work experience and the process of their vicarious learning. The result of the current study has a practical implication in terms of providing a basic perspective for career education for students of colleges.

This study aims to suggest a development process for the interior design major course at K University's school of design to educate specialists who can answer the needs of the industrial field. The study procedure first analyzed the internal and external environment to establish queries and development direction. A job model for the interior design industry was constructed while course modules were deducted based on job characteristics and was used to form a curriculum based on a 4 year course. Required personnel includes 'Interior Design Business and Marketing Specialists', 'Interior Design Space Planning Specialists' and 'Interior Design Construction Management Specialists'. 40 modules were drawn following the detailed job model structure. 1st year students are to follow a common curriculum, 2nd years the major foundation, 3rd years major intensive, and the 4th years major application. The practical importance of the research is to suggest a development process of major modules based on the standard job model and the organization structure of the interior design industry.

Recently, in the smart construction field, it is possible to construct spatial information of 3D data base quickly and accurately using drones, LiDARs and ARs,. Most public ordering institutions are pushing for the efficiency of construction work through establishing and announcing road maps and guidelines for utilizing BIM for the entire life cycle of construction. However, in most policies, the impact of 3D data on the entire life cycle is limited by only partially constructing and utilizing 3D data or by being mentioned. In addition, many public institutions, construction companies and planning companies did not actively utilize survey information during the actual construction phase, despite the possibility of using 3D survey information. In order to confirm the utilization of survey information, a total of eight private construction companies were selected and interviewed by experts. The analysis shows that most of companies lack the performance of drone measurements or have a lack of awareness of advantages, and among them, construction companies are relatively active. Based on these opinions, this study examined the usability of surveying information and examined measures to expand the utilization of survey information in legal and institutional aspects, technology development aspects and industrial development.

소스 코드 식별자의 이름을 잘 정하는 것은 소프트웨어 엔지니어링에서 중요한 문제로 다루어지고 있다. 프로그램 엔티티의 의미있고 간결한 이름은 코드 이해도에 중요한 역할을 하며, 소프트웨어 유지보수 관리 비용을 줄이는 데에 큰 효과가 있다. 이러한 코드 식별자 중 평균적으로 가장 복잡한 식별자는 '메소드 이름'으로 알려져 있다. 본 논문에서는 메소드 내용과 일관성 있는 적절한 메소드 이름 생성을 자연어 처리 태스크 중 하나인 '추상적 텍스트 요약'으로 치환하여 수행하는 트랜스포머 기반의 인코더-디코더 모델을 제안한다. 제안하는 모델은 Github 오픈소스를 크롤링한 Java 데이터셋에서 기존 최신 메소드 이름 생성 모델보다 약 50% 이상의 성능향상을 보였다. 이를 통해 적절한 메소드 작명에 필요한 비용 절감 달성 및 다양한 소스 코드 관련 태스크를 언어 모델의 성능을 활용하여 해결하는 데 도움이 될 것으로 기대된다.

안드로이드는 오픈소스로 많은 제조 업체들이 자신들의 서비스에 맞게 커스터마이징 하기도 한다. 다만, 접근 제어 정책들을 올바르지 못하게 수정하거나 추가함에 있어서 발생하는 취약점을 통해 공격자가 해당 접근 제어 메커니즘을 우회하여 보안적 위험 문제가 발생할 수 있다. 이에 따라 안드로이드의 다양한 접근 제어 정책들을 살펴보고, 제조 업체가 추가하는 접근 제어 정책을 검사하거나 발생하는 취약점에 따라 우회할 수 있는 방법들을 찾아내는 최근 연구들의 동향을 분석하고자 하며 앞으로의 관련 연구의 지속적인 필요성을 제시한다.

본 논문에서는 열화상 카메라 및 주변 환경요인 측정 시스템을 이용하여 각종 반도체 제조공정에 사용되는 화학물질의 누수를 검출하는 방안을 제안한다. 이는 대형화되고 복잡한 집적배관이 시공되어 있는 공장 환경에서 검출센서를 통한 화학물질 누수 관리를 열화상 시스템으로 대체함으로써 보다 정확하고 안정적인 모니터링을 통해 신속한 대응 및 관리가 가능할 것이다. 또한 본 연구를 통해 누수 배관표면의 열패턴을 실시간으로 모니터링 함으로 기존 누수 검출 센서(면적식 라인타입의 센서)에 대비하여 20% 이상 검출의 신속성 향상을 보장할 수 있다.

With the recent advances in communication technology and Internet of Things (IoT) infrastructure, home automation systems have emerged as a new paradigm for providing users with convenient smart home services. The IoT ecosystem has merged digital systems with the physical world, dramatically changing the way people live and work. However, at the same time, security remains one of the most significant research issues in IoT, as the deployment and application of high-availability systems come with various security risks that cause serious threats to users. Among them, the security issues arising from the interaction among devices/applications should not be underestimated. Attackers can exploit interactions among devices/applications to hack into the user's home. In this paper, we present a survey of research on detecting various types of interactions among devices/applications in IoT.
