Purpose: The world saw a shift into a new society consequent to the coronavirus disease 2019 (COVID-19), which made home quarantine mandatory for a person in close contact with those who tested positive. For children, however, home quarantine was not limited only to themselves but parents, especially mothers were involved and required to quarantine. This qualitative study aims to explore and understand mothers' experience and their related psychosocial issues while caring for their school-aged children in Korea, who had to home quarantine after coming in close contact with COVID-19 positive individuals. Methods: Data were collected from October 2020 to January 2021 via in-depth, semi-structured interviews with nine mothers of children who had to home quarantine. Interviews were conducted face-to-face in an independent space near the participant's home or workplace (n=5) or via online platforms or telephone (n=4). The data were analyzed using thematic analysis through several iterative team meetings. Results: Thematic analysis revealed the following four themes: "Unable to be relieved due to uncertain situations surrounding me," "Blame and hurt toward me, others, and one another," "Pulling myself together for my children in my broken daily life," and "Changes in the meaning of life amid COVID-19." Conclusion: The narratives show that mothers experienced psychosocial difficulties while caring for their children during home quarantine. It is necessary to reduce the social stigma toward individuals in home quarantine and establish policies to ensure work-family compatibility for such mothers.

Electronic learning (e-learning) empowers the higher education in providing sustainable instruction during the infrequent circumstance when the wide-spreading disastrous challenge of the COVID-19 results in the closure of various sectors in the society. During this time, e-learning serves the levels of the education sector such as higher education well by delivering and receiving materials from distance with respect to movement restrictions imposed by the government, for example the Movement Control Order (MCO) in Malaysia. In this qualitative survey, the existing e-learning challenges and the recommended solutions to the problems from the senior lecturers' perspectives were collected through an online open-ended questionnaire. A number of five senior lecturers out of eight at the Universiti Teknologi Malaysia (UTM) answered the questionnaire. The UTM has been capable of providing e-learning courses for all of its lecturers and students during the closure of higher education institutions owing to the pernicious health conditions stemmed from the crisis of the COVID-19. The major existing challenges found in the e-learning program at the UTM and the suggested solutions to address them are listed and the main themes are illustrated in the word cloud format using the NVivo software. In the end, the conclusion is paragraphed and the future work is proposed. Overall, the purpose of this study is to address the e-learning challenges and to prepare a list of recommendations that can serve as solutions from the standpoint of the UTM senior lecturers during the MCO in Malaysia.

High resolution aerial photographs and digital elevation models for Bangpo beach using UAV were generated in this study to analyze the thematic and geometric characteristics of coastal features. Based on 728 aerial images acquired on September 10, 2016 by the UAV, a image mosaic at 2.2 cm spatial resolution and a digital elevation model at 4.4 cm spatial resolution were developed. This study found out that Bangpo beach consisted of intertidal zone and supratidal zone. The intertidal zone can be subdivided into lower part and upper part with distinctive geomorphological characteristics. While the lower part included sand bars and ripple marks along the coastline, the cusps and sand dunes were the major coastal features of the upper part. Part of the intertidal zone was occupied by shore platform with average slope of 0.9 degree containing various sizes of gravels. The supratidal zone slanted toward ocean with berms on the surface with an interval of 15 m. These coastal features indicated the flow intensity towards to the land and tidal effect. It validated that the UAV application in coastal research was very effective analyzing to examine coastal processes.

KOMPSAT-3 is expected to provide data with 80-cm spatial resolution, which can be used to detect environmental change and create thematic maps such as land-use and land-cover maps. However, to analyze environmental change, change-detection technologies that use multi-resolution and high-resolution satellite images simultaneously must be developed and linked to each other. This paper describes a GIS-based strategy and methodology for revealing global and local environmental change. In the pre-processing step, we performed geometric correction using satellite, auxiliary, and training data and created a new classification system. We also describe the available technology for connecting global and local change-detection analysis.

Plagiarism occurs when the content is copied without permission or citation, and the problem of plagiarism has rapidly increased because of the digital era of resources available on the World Wide Web. An important task in plagiarism detection is measuring and determining similar text portions between a given pair of documents. One of the main difficulties of this task is that not all similar text fragments are examples of plagiarism, since thematic coincidences also tend to produce portions of similar text. In order to handle this problem, this paper proposed association analysis in data mining to detect plagiarism. This method is able to detect common actions performed by plagiarists such as word deletion, insertion and transposition, allowing to obtain plausible portions of plagiarized text. Experimental results employing an unsupervised document classification strategy showed that the proposed method outperformed traditionally used approaches.

The 4 sets of environmental variables dealing with meteorology, hydrology and physiography were analyzed to generate a spatial drought risk index of Phitsanulok province of Thailand. The analysis of K-mean and discriminant were applied to the set of the selective drought variables for grouping each of spatial variable set into 4 classes. The obtained 4 classes, based on group statistics, were thus recoded in the meaning of no risk, low risk, moderate risk, and high risk. The regression coefficient between recoded classes and a set of the selective environmental variables were then applied as spatial variable weighting on thematic dataset in GIS spatial analysis. The results showed that the weighting score of drought variable was highest in meteorological variable compared to other variables.

대학연습림의 기능이 점차 확대되면서 산림 및 자연환경에 대한 다양한 정보가 필요하게 되고, 연습림의 관리전략에도 복잡한 기술이 요구되고 있다. 따라서 GIS 기법을 응용한 소위 산림정보시스템과 같은 체계적 수단을 통해 산림 및 입지환경에 대한 여러 가지 정보들을 보다 손쉽게 수집, 편집, 관리, 분석, 갱신하고 나아가 의사결정을 지원할 수 있다면 연습림의 관리에도 많은 효과를 얻을 수 있게 된다. 본 연구는 대구대학교 성주연습림을 대상으로 이러한 목적을 시범적으로 모색해보고자 한 것으로, 일차 단계로서 각종 공간자료를 수치지도화 하여 지형을 비롯한 임상, 토양형 등 여러 수치주제도를 구축함으로써 도면정보의 유지 및 통합과정의 어려움을 해소하면서 위치적 통일성과 정보의 통합성을 어느 정도 확보하였다. 또한 영림계획상의 속성자료와 연결하여 사용자 중심의 시스템을 개발함으로써 보다 신속한 검색, 분석은 물론 각종 산림계획의 수립, 평가, 실행과정의 의사결정 수단으로 활용할 수 있었다. 그러나 시스템의 기능에 대한 다양한 요구에 부응하고 효용성을 높이기 위해서는 최신 자료로의 갱신이나 새로운 기술의 도입 등 문제점에 대한 지속적인 보완이 필요할 것으로 생각된다.

본 연구는 인터넷발달의 과정에서 발달단계인 초기(보급 확산)부터 보편적으로 활용되고 있는 사회문화기인 현재까지 발달과정을 실증적이며 이론모델을 제시한 연구이다. 전통적인 매체에서 어떠한 방식으로 보도해왔는가를 통해 각 시기별로 나타나는 미디어적특성을 이해하는데 그 목적이 있다. 주요 뉴스미디어들이 어떠한 보도경향-틀 짓기(프레임)-방식으로 인터넷발달을 기록해 왔는지를 살펴보았다. 이를 위해 1989년부터 2004년까지의 기사를 대상으로 내용분석을 실시했다. 또한, 인터넷의 기술발전과 이용추이에 따라 4시기로 구분했는데 인터넷 상용화이전 도입기, 인터넷 확산기, 인터넷의 상업적 상용화기, 인터넷의 사회 문화기가 그것이다. 분석결과, 신문보도의 프레임 요소와 방법은 각 시기별로 대체적으로 차별적인 방식으로 구성되었다. 특히 사회 문화기로 접근할수록 초기의 기술위주의 계열화방식에서 점차적으로 통합화 방식으로 전환되어 왔다. 결국, 인터넷의 이용 폭이 확대되고 사회전반으로 그 영향력 범위가 넓어짐에 따라 신문은 사회 안에서 인터넷이 갖고 있는 의미와 문제점 등에 초점을 맞추었다는 것이다. 그러나, 기존의 미디어 대체적 시각에서 바라보는 것과 같은 경쟁적인 프레임이나 보도경향은 뚜렷하게 드러나지 않았다. 오히려 인터넷의 도입 이후 장기적으로 국가차원 이용과 같은 주제보도(thematic coverage) 차원으로부터 일상적인 이용보도인 일화보도(episodic coverage)가 많은 쪽으로 옮아갔다. 장기적으로 인터넷 보도시각은 변화양상을 보여 왔으나, 어느 한 측면(낙관적 혹은 비관적, 호의적 또는 비호의적)에 치우치지 않고 대체로 중립적인 프레임을 실증적으로 확인하였다.

Objectives: Spatial analysis is useful for understanding complicated causal relationships. This paper focuses trends and appling methods for spatial analysis associated with environmental asbestos exposure. Methods: Literature review and reflection of experience of authors were conducted to know academic background of spatial analysis, appling methods on epidemiology and asbestos exposure. Results: Spatial analysis based on spatial autocorrelation provides a variety of methods through which to conduct mapping, cluster analysis, diffusion, interpolation, and identification. Cause of disease occurrence can be investigated through spatial analysis. Appropriate methods can be applied according to contagiousness and continuity. Spatial analysis for asbestos exposure source is needed to study asbestos related diseases. Although a great amount of research has used spatial analysis to study exposure assessment and distribution of disease occurrence, these studies tend to focus on the construction of a thematic map without different forms of analysis. Recently, spatial analysis has been advanced by merging with web tools, mobile computing, statistical packages, social network analysis, and big data. Conclusions: Because the trend in spatial analysis has evolved from simple marking into a variety of forms of analyses, environmental researchers including asbestos exposure study are required to be aware of recent trends.
