A great deal needs to be learned about why and how users participate and consume information on various online sites. The design of socio-technical systems especially for promoting engagement in terms of maximum user participation is both a theoretical and real-world challenge that researchers strive to understand. At present, most of the research on the motives of Internet video users' behavior focuses on the user's "viewing motivation" and "sharing motivation", and lacks the analysis of the factors affecting users' "subscription motivation". This study will attempt to compensate for this gap. Based on the YouTube platform, we take Chinese video users as the research object and uses the "Censydiam user motivation analysis model" to make assumptions about user subscription motivation from the two levels of social needs and personal needs, using regression analysis. Validate the hypothesis and get the influencing factors that may be available in the user's subscription motivation based on the assumptions. Built on survey data from 215 respondents, the study found that Enjoyment, Vitality, Power, and Conviviality are four factors that influence user motivation.

인스턴트 메신저는 현대인의 의사소통 수단으로 스마트폰과 PC 등에서 이용 가능하며, 개별로 사용하거나 연동해서 사용할 수 있다. 메시지, 통화 및 파일 공유 등의 다양한 기능을 제공하는 메신저는 사용자의 행위정보를 포함하므로 포렌식 수사관점에서 중요한 증거로서의 가치를 지닌다. 하지만 스마트폰 데이터는 데이터 추출의 어려움이나 제작자의 보안기술 적용으로 분석의 어려움이 있다. 그러나 스마트폰과 PC 메신저를 연동해 사용하고 있는 경우 스마트폰 대신 PC에서 대화 내용 및 사용자 데이터 획득이 가능하다. 본 논문에서는 Windows 10 환경에서 Wire 메신저의 크리덴셜 정보를 획득했으며, 다른 PC에서 인증 과정 없이 로그인 가능함을 보였다. 또한, 사용자 행위를 기반으로 생성되는 주요 아티팩트 선별하고 정리하였다.

Objectives: The purpose of this study is to explore the research trends of elderly oral health through a language network analysis. Methods: A total of 354 published studies with 668 keywords were collected from the Research Information Sharing Service (RISS) between 2000 and 2022. Language network analysis was performed using Textom 6.0, Ucinet 6.774, and NetDraw 2.183. Results: The most frequent keywords were 'elderly', 'oral health', 'quality of life', and 'OHIP-14'. The result of frequency-inverse document frequent keywords showed similar results to the most frequent keywords. The N-gram of keywords shows that 'elderly', 'oral health' (18 times) and 'elderly', 'depression' (7 times). As a results of the analysis of degree centrality and between centrality, 'elderly', 'oral health', and 'quality of life' were found to be high. The CONCOR analysis identified the main clusters of 'quality of life', 'oral health behavior', 'health', and 'oral function disorder'. Conclusions: The results of the current study could be available to know research trends in elderly oral health and it is necessary to improve more comprehensive study in follow-up study.

본 연구는 금연을 실천 및 유지하는 소비자들의 정보요구와 정보탐색행태를 조사하고, 다양한 단계에서 얻은 건강 정보가 건강 행동 변화에 미치는 영향을 분석하는 데 목적이 있다. 특히 이 연구에서는 소비자가 건강에 해로운 행동을 변경하는 데 도움이 되는 모바일 건강 애플리케이션(건강 앱)을 사용하는 방법과 금연 앱 사용이 건강 행위 변화에 미치는 영향을 조사했다. 이 연구는 금연 앱을 사용하는 대학생을 대상으로, 2017년 12월부터 2018년 7월까지 7개월 동안 참여자의 흡연 행동 변화를 관찰하고 대면 인터뷰를 실시했다. 실천단계의 참여자들에 따르면, 금연 기간, 건강 상태 변화, 금연으로 인한 비용 절감 등의 시각화된 정보가 금연을 독려했다. 유지 단계의 참여자들은 금연 앱이 제공하는 커뮤니티를 통해 다른 금연시도자들과 자신의 경험 및 사회적 지원을 공유함으로써 금연의 중요성과 성취를 인식하는 데 도움이 된다는 것을 강조했다. 이 연구는 행동 수정 과정에서 모바일 앱을 사용하는 건강 정보 소비자의 정보 요구 및 정보탐색행태의 유형을 식별했다는 점에서 정보 행위 분야에 이론적 함의를 제공한다. 연구 결과는 금연 시도자의 정보 요구를 반영한 금연 앱의 콘텐츠 설계에 기여할 수 있으며, 나아가 건강 행위 변화에 효과적인 정보 중재 전략을 촉진하는 건강 정보 서비스에 대한 실질적인 통찰을 제시할 수 있다.

The general design practice for piled footings is based on the assumption that the piles are free-standing, and that all the external loads are carried by the piles, with any contribution of the footing being ignored. This approach is not reasonable, because the footing itself is actually in direct contact with the soil, and thus carries a significant fraction of the loads. In the case of not considering the bearing capacity of footing, the bearing capacity of group piles can be evaluated conservatively in the designing the group piles. There are a number of reasons why the idea of piled raft design with considering the capacity of footing has not become widely used. One of the reasons is the lack of reliable calculation methods for estimating the behavior of piled raft. In this study the bearing capacity, settlement, load distribution, etc. of piled raft footing are studied.

As consumers participate in sharing their experiences, they become a powerful information source in online shopping malls. Previous studies have investigated information service in the company-created information perspective and trust in the company perspective. This study extends the perspective of company-consumers to consumers-consumer perspective in information satisfaction and trust. Also, this study suggests loyalty as voluntary behaviors and adds helping behavior to the loyalty. Our results show that information satisfactions influence trust in the information sources such as company and consumers. Moreover, trust in company and trust in consumers influence loyalty differently. While trust in company influences recommending stronger than trust in consumers, trust in consumers influence helping and repurchasing stronger than trust in company.

SNS is perceived as an effective tool for sharing news and enabling news content to reach many more users than before. And some users think that SNS is an important source to get news. This study's purpose is to understand the key factors contributing to behavior of news consumption on social network sites in Cambodia and its influence. We identified three key factors including convenience, recency, and variety; however, recency showed less significant effect on news consumption on SNS. Besides the key factors, it also seeks to understand the impact of news consumption on social engagement and government's transparency in Cambodia. The analytical results achieved through the Partial Least Squares (PLS) approach.

This paper presents linear algebraic equations in the form of recursive formula to compute elastokinematic characteristics of a suspension system. Conventional methods of elastokinematic analysis are based on nonlinear kinematic constrant equations and force equilibrium equations for constrained mechanical systems, which require complicated and time-consuming implicit computing methods to obtain the solution. The proposed linearized elastokinematic equations in the form of recursive formula are derived based on the assumption that the displacements of elastokinematic behavior of a constrained mechanical system under external forces are very small. The equations can be easily computerized in codes, and have the advantage of sharing the input data of existing general multi body dynamic analysis codes. The equations can be applied to any form of suspension once the type of kinematic joints and elastic components are identified. The validity of the method has been proved through the comparison of the results from established elastokinematic analysis software. Error estimation and analysis due to piecewise linear assumption are also discussed.

Purpose. To examine the effect of Taegyo-focused prenatal classes on maternal-fetal attachment and self-efficacy related to childbirth. Methods. Over 4 weeks, 49 women, 20 to 36 weeks of gestation participated in a prenatal program led by the nurse who developed it. In addition to Lamaze content it included; understanding ability of fetus to respond, sharing motivation, purpose of pregnancy, and preconceptions of experiencing childbirth, training in maternal-fetal interaction, writing letters and making a declaration of love to unborn baby. Using a pre-experimental design, data were collected by self-report, before and after program, using Cranley's Maternal-Fetal Attachment Scale (1981), and Shin's(1997) Labor Self-Efficacy Measurement. Results and Conclusion. Paired t-test showed significant changes in scores of maternal-fetal attachment (t=6.91. p<.001) and self-efficacy related to childbirth (t=10.19, p<.001). Taegyo opens the possibility of integrating Western ideas with Korean traditional health behavior. Incorporation of Taegyo into existing prenatal classes is recommended.
