This study was to investigate the factors influencing colorectal cancer(CRC) screening behavior using the health belief model(HBM). It was a descriptive cross-sectional survey. A total of 148 adults aged 50 or older participants were surveyed using structured questionnaires including general characteristics,, health beliefs, and behavioral variables. The data were analyzed by descriptive statistics, t-test, chi-square test and multiple logistic regression using SPSS/WIN 25.0 program. The significant factors influecing CRC screening behavior were perceived sensitivity, spousal experience of CRC screening and family history. Therefore, in order to improve the CRC screening rate, it is necessary to increase the perceived sensitivity through systematic education about the importance of early CRC screening. In addition, it is necessary to assess the spousal screening experience and the family history of subjects and to develop the education program using the partnership of the couple.

This article shows how the tradition of German historicism and positive historical science contributed to the establishment of German archival system, especially the principle of provenance and original order. The theory of historicism focused on the recognition and realization of the individuality of the history as a whole unit which is made up of the mutually and organically organized cultural entities. The theory of historicism as this kind of world view got its academic basis from the methodology of the positive historical science, namely the critical reviews on the archival sources which exist in mutually and organically organized record entities. In this context, the scholars of the historicism saw the establishment of the efficient archival systems as necessary. To some great degree, the emergence of the principle of the provenance and original order was its logical result. The author of this paper tried to highlight this point of view historically, on the basis of the activities of Ranke, Sybel and Lehmann around and in the Prussia Privy State Archives throughout the 19th century.

This study analyzed the problems that occurred while constructing and operating the cloud record management system at the record management workplace and suggested ways to improve the system. In the study, the cloud record management system has the following problems: first, it has not been accompanied by the change in the legislative system. Second, it has not been utilizing the benefits of cloud technology. Third, it has not been considering the changes after the system construction. Given this, the study suggested three improvement plans to solve these problems: first, in relation to the reformed legislative system, the study proposed the diversification of records management units (file-item structure) and the restriction on access to records. Second, the study suggested a system redesign by improving the current work process based on paper documents. Third, to solve records management issues, the study presented the establishment of the governance body and the proactive countermeasure of the National Archives of Korea.

This study aims at deriving the implications for adaptation policy and research target regarding climate change risk assessment in ecosystem sector in Korea. The common ground of exemplary cases of "world leaders" in terms of adaptation policies and researches was that they emphasize nationwide study on climate change on biodiversity and ecosystem in target of establishing scientific evidence-bases and reducing uncertainty for their national adaptation policies and plans. In light of this trend, Korean government should settle down more successful adaptation structure by leading adaptation system in further national policy-settings to observe UNFCCC and CBD integratedly and effectively, considering the economic value of adaptation in policy, and strengthening scientific research programs and technology developments. Moreover, risks assessment based on diagnoses and analysis on the risk factors (hazard, exposure, and vulnerability) for climate change in nationwide habitats and species and consolidations with subsequent adaptation strategies could make adaptations in ecosystem sector more effective and successful.

There are many large and small spaces in the interior of the building, and these spaces are arranged and connected to form a systematic spatial structure. A structure is a collection of several parts to form a whole. In other words, the spatial structure in architecture can be seen as a whole organized and organized as individual unit spaces are gathered together. Therefore, in order to understand the spatial structure, we first need to define the unit spaces that form part, how they are interconnected and arranged, and then understand how and how these unit spaces are organized to form a whole. The main purpose of this study is to study the structural system of space based on the shape information of space on architectural plane. This means interpreting the process and method of how the unit spaces defined as a certain shape on the architectural plane are organized step by step, integrated into a higher level, and eventually integrated into one whole. In this paper, the shape and layout of the unit space are identified in the architectural plan, the connection relation is defined, and expressed in the network form. And suggests a new methodology for interpreting the organizational process in which the following spaces are integrated as a whole. This new methodology is based on human perceptual characteristics. When people recognize an object, they recognize the object partly and completely. We want to explain the relationship between parts of space and the whole according to their characteristics.

We explored the performance improvement method of automated scoring for scientific argumentation. We analyzed the pattern of argumentation using automated scoring models. For this purpose, we assessed the level of argumentation for student's scientific discourses in classrooms. The dataset consists of four units of argumentation features and argumentation levels for episodes. We utilized argumentation clusters and n-gram to enhance automated scoring accuracy. We used the three supervised learning algorithms resulting in 33 automatic scoring models. As a result of automated scoring, we got a good scoring accuracy of 77.59% on average and up to 85.37%. In this process, we found that argumentation cluster patterns could enhance automated scoring performance accuracy. Then, we analyzed argumentation patterns using the model of decision tree and random forest. Our results were consistent with the previous research in which justification in coordination with claim and evidence determines scientific argumentation quality. Our research method suggests a novel approach for analyzing the quality of scientific argumentation in classrooms.

In this paper, we propose operations and maintenance (O&M) planning approach for floating offshore wind farm using the mathematical optimization. To be specific, we present a MILP (Mixed Integer Linear Programming that suggests the composition of vessels, technicians, and maintenance works on a weekly basis. We reflect accessibility to wind turbines based on weather data and loss of power generation using the Jensen wake model to identify downtime cost that vary from time to time. This paper also includes a description of two-stage approach for maintenance planning & detailed scheduling and numeric analysis of the number of vessels and technicians on the O&M cost. Finally, the MILP model could be utilized in order to establish the suitable and effective maintenance planning reflecting domestic situation.
