정다인 ( Jeong¸ Da-in ),김충식 ( Kim¸ Choong-sik ) 한국전통조경학회 2021 한국전통조경학회지 Vol.39 No.3

정자는 전통 조경에서 중요한 경관적 장치이자 공간을 구성하는 대표적인 시설이다. 전통 조경공간에 대한 해석과 계승을 위해서는 전통 정자의 형상과 구조에 대한 연구도 동반되어야 한다. 하지만 전통 정자의 양식과 구조에 관한 연구는 찾아보기 어렵다. 이에 본 연구는 정자의 형상을 결정짓는데 가장 비중이 큰 지붕부를 대상으로 구조적 특성의 규명을 목적으로 하였다. 연구결과는 다음과 같다. 구조를 파악할 수 있는 15개의 한칸형 전통 사각정자를 대상으로 분석한 결과 한 칸 정자의 지붕부의 유형을 구분짓는 주요 부재는 보, 종도리, 동자임을 확인하였다. 지붕 부재의 유무에 따라 정자는 보, 보+종도리보+동자, 종도리, 동자 등 5가지 유형으로 분류되었다. 또한 지붕부의 형상 분류를 토대로 보에 작용하는 하중과 결구를 분석한 결과 한칸형 전통 사각정자에서 보가 수장과 하중의 균형을 이루는 역할을 하기 위한 것임을 확인하였다. 본 연구는 정자 지붕부의 형태와 부재의 역할과 기능에 대해 크기, 비율, 하중 등으로 면밀하게 해석을 시도하였다는 점에서 의의가 있다. Pavilion is an important landscape installation in the traditional landscaping and a representative facility that organizes space. To interpret and succeed the traditional landscape space, researches on the shape and structure of the traditional pavilion are also needed. However, researches on the style and structure of the traditional pavilion are difficult to be found. Accordingly this study aimed to identify the structural characteristics of roof part that occupied the largest portion in determining the shape of pavilion. Our research findings are as follows. As a result of analyzing 15 traditional Single-room square pavilions whose structure could be identified, it was found that the main building elements that distinguished the type of roof part in the Single-room square were crossbeam, ridge pole, and baluster. Depending on the presence of roofing members, pavilion was classified into five types: crossbeam, crossbeam+ridge pole, crossbeam+baluster, ridge pole, and baluster. In addition, as a result of analyzing the load and joint that worked on crossbeam based on the shape classification of roof part, it was found that in the traditional Single-room square pavilion, crossbeam was designed to play a balancing role between pillar and load. This study is significant in that it attempted to make a close interpretation of the shape of roof part in the pavilion and the role and function of building elements in terms of size, ratio, and load.

박우연(Woo-Yeon Park),정다임(Da-Im Jeong) 글로벌융합연구학회 2022 글로벌융합연구학회지 Vol.1 No.1

ICT기술이 발전하면서 신기술의 적용은 금융 산업이 틈새시장에 서비스를 제공하여 보편금융, 소액금융 및 지혜금융으로 변화와 발전을 촉진할 것이다. 따라서 핀테크 기반의 모바일 자산관리를 하는 사용자들의 어떤 요인이 사용 의도에 영향을 미치는지를 분석할 필요가 있다. 시작은 제3자 결제 도구지만 지금은 새로운 자산관리 도구로 변모한 알리페이를 중심으로 모바일 핀테크 기반의 금융서비스 특성요인이 고객 사용 의도에 어떤 영향을 주는지에 대한 실증분석을 수행하였다. 본 연구에서는 금융서비스 특성, 고객만족도 및 사용의도에 관한 선행연구를 검토한 후 실증적 연구를 수행하였다. 수집된 데이터는 SPSS 22.0을 기본 통계로 사용하고, Smart PLS 2.0(Partial Least Squared)의 구조방정식을 사용하여 분석하였다. 연구 결과는 다음과 같다. 첫째, 금융서비스 특성(편의성, 혜택성, 보안성, 유연성)은 고객만족도에 유의한 영향을 미쳤다. 둘째, 고객만족도는 사용 의도에 유의한 영향을 미쳤다. 이는 급속도로 변화하는 시장환경에 기업의 빠른 정착을 위해서는 차별적인 금융서비스의 수립이 필수적이라는 것을 의미한다. 모바일 시장에서 고객을 확보하기 위해서는 금융서비스 특성의 적극적인 활용이 필요하다. The world's ICT technology develops, the application of new technology will facilitate the change and development of the financial industry into universal, microfinance and wisdom financing by providing services to niche markets. Therefore, it is necessary to analyze which factors affect the intention of users using FinTech-based mobile asset management. Starting from a third-party payment tool, but now, Alipay, which has been transformed into a new asset management tool, we conducted an empirical analysis of how financial service characteristics affect customer intention on mobile FinTech. Empirical studies were conducted after reviewing previous studies on financial service characteristics, customer satisfaction, and use intention. Collected data were analyzed using SPSS 22.0 as basic statistics and Smart PLS 2.0 (Partial Least Squared) using structural equations. The research results are as follows. First, the characteristics of financial services (convenience, benefit, security, and flexibility) had a significant effect on customer satisfaction. Second, customer satisfaction had a significant effect on use intention. This means that in order to settle in the market, it is essential to establish differentiated financial services in a rapidly changing business environment. In order to attract customers in the mobile market, it is necessary to actively use the characteristics of financial services.

어린이용품 노출평가 연구에서의 결정론적 및확률론적 방법론 사용실태 분석 및 고찰

장보윤(Bo Youn Jang),정다인(Da-In Jeong),이헌주(Hunjoo Lee) 한국환경보건학회 2017 한국환경보건학회지 Vol.43 No.3

Objectives: In response to increased interest in the safety of children s products, a risk management system is being prepared through exposure assessment of hazardous chemicals. To estimate exposure levels, risk assessors are using deterministic and probabilistic approaches to statistical methodology and a commercialized Monte Carlo simulation based on tools (MCTool) to efficiently support calculation of the probability density functions. This study was conducted to analyze and discuss the usage patterns and problems associated with the results of these two approaches and MCTools used in the case of probabilistic approaches by reviewing research reports related to exposure assessment for children s products. Methods: We collected six research reports on exposure and risk assessment of children’s products and summarized the deterministic results and corresponding underlying distributions for exposure dose and concentration results estimated through deterministic and probabilistic approaches. We focused on mechanisms and differences in the MCTools used for decision making with probabilistic distributions to validate the simulation adequacy in detail. Results: The estimation results of exposure dose and concentration from the deterministic approaches were 0.19–3.98 times higher than the results from the probabilistic approach. For the probabilistic approach, the use of lognormal, Student s T, and Weibull distributions had the highest frequency as underlying distributions of the input parameters. However, we could not examine the reasons for the selection of each distribution because of the absence of test-statistics. In addition, there were some cases estimating the discrete probability distribution model as the underlying distribution for continuous variables, such as weight. To find the cause of abnormal simulations, we applied two MCTools used for all reports and described the improper usage routes of MCTools. Conclusions: For transparent and realistic exposure assessment, it is necessary to 1) establish standardized guidelines for the proper use of the two statistical approaches, including notes by MCTool and 2) consider the development of a new software tool with proper configurations and features specialized for risk assessment. Such guidelines and software will make exposure assessment more user-friendly, consistent, and rapid in the future.
