Purpose: Thisstudy aims to measure the attitudes of Generation Z in Jakarta towards advertisements containingCOVID-19 information. Research design, data and methodology: This study is a quantitative method with partial least square structural equation modeling (PLS-SEM) with SMART PLS as an analytical tool. The sample size is 216 participants was obtained randomly through a questionnaire distributed online. This study consisted of exogenous variables (advertising content, value, irritation, and economic benefits), endogenous variables (attitudes towards advertising), and some moderating roles. Results: The results of thi study explain that this generation's attitude towards advertising is affected by the content and value aspects embedded in advertisements. Value can be formed from creativity in making advertising content as interesting and informative as possible. Interestingly, this study also found that the irritation aspect and economic benefits had no effect on the audience's attitude towards the advertisement. Neither the irritating aspect of advertising nor the economic value that is formed acts as a moderator of the content and the value of the ad. Conclusions: The ongoing pandemic and periodic adjustments to government policies regarding COVID-19, these results can be compared with other advertisements for future studies, especially those using the same variables as this study.

이 연구에서는 집중호우로 인해 발생하는 토사비탈면의 표층붕괴 징후를 파악하기 위해 체적함수비의 변화특성을 분석하였다. 붕괴가 발생한 조건과 발생하지 않은 조건에서의 체적함수비 변화특성을 파악하기 위해 실내토조실험과 테스트베드에서 확보한 체적함수비 계측자료를 비교하였다. 본 연구에서 확보한 282개의 체적함수비 계측자료를 분석한 결과, 붕괴가 발생한 경우의 체적함수비 증가기울기는 0.072~0.309 범위에 분포하고 붕괴가 발생하지 않은 테스트베드의 경우에는 0.01~0.32의 값을 가져 특정값을 기준으로 붕괴 유무가 구분되지는 않았다. 그러나 체적함수비 증가기울기 값이 높아질수록 붕괴가 발생하는 경향이 뚜렷하게 나타났으며 이를 이용하여 4단계의 경보기준을 제시하였다.

As the Internet is more embedded in people's lives, Internet users draw on new Internet applications to express themselves through "user-created content (UCC)." In addition, there is a noticeable shift from text-centered contents mainly posted on bulletin boards to multimedia contents such as images and videos on UCC web sites. The changes require different way of recommendations comparing to traditional products or contents recommendation on the Internet. This paper aims to design UCC recommendation methods with user behavior data and contents metadata such as tags and titles, and compare performances of the suggested methods. Real web logs data of a major Korean video UCC site was used to empirical experiments. The results of the experiments show that collaborative filtering technique based on similarity of UCC customers' preferences performs better than other content-based recommendation methods based on tag information and content metadata.

The game industry has changed along with the advancement of device technology. The wearable, a recently appeared device will create new demand in this saturated age of the smart devices. The game industry's content targeted towards the wearable devices will play an important role as main driving source. For this reason, this research studies the development aspect and the current technical capabilities of games' platforms and contents by analyzing the contrast between the results of features and current situations of the wearable market. Consequently, we define the prospects of game content for wearable device. We also expect that the new style of the game content, combined with cloud game, augmented reality game and virtual reality game will appear in the next generation platforms gearing towards the wearable devices.

4D models help construction planners to develop and evaluate construction plans. However, current analyses using 4D models are mainly visual and limit the quantitative comparison of construction alternatives. This paper explores the usefulness of extracting quantitative information from 4D models to support time-space analyses. We use two 4D models of an industry test case to illustrate how to analyze 4D content quantitatively (i.e., work space areas and distances between concurrent activities). This paper shows how these two types of 4D content can be extracted from 4D models to support 4D-based-analysis and novel presentation of construction planning information. We suggest further research to formalize the content of 4D models to enable comparative quantitative analyses of construction planning alternatives. Formalized 4D content will enable the development of reasoning mechanisms that automate 4D-model-based analyses and provide the information content for informative presentations of construction planning information.

본 연구의 목적은 대학운동선수들을 대상으로 자기관리 구성개념을 개방형 질문지와 포커스 그룹 인터뷰(Focus Group Interview)의 두 가지 통합연구방법을 통하여 규명하고자 하였다. 자료 수집은 서울 경기 소재 대학에 재학 중인 운동선수 157명을 대상으로 개방형 질문지를 실시하였으며 또한 대학운동선수 14명을 대상으로 포커스 그룹 인터뷰를 실시하여 자료를 수집하였다. 이에 일련의 연구절차를 통하여 도출된 결과는 다음과 같다. 첫째, 개방형 질문지의 귀납적 내용분석 결과 대학운동선수들의 자기관리는 생활관리, 훈련관리, 시합관리, 정서관리, 학업관리, 대인관리, 목표(동기)관리, 장비관리로 8가지 일반영역이 도출되었다. 둘째, 포커스 그룹 인터뷰 결과에서는 귀납적 내용분석을 보다 타당성 있게 지지하고, 스포츠 현장 중심적인 면담 사례들이 심도 있게 도출되었다. 본 연구의 결과들은 대학운동선수의 성공적인 선수생활을 위한 전략 수립과 대학운동선수들의 자기관리 측정도구 개발에 기초자료로서 활용될 수 있을 것이다.

본 사용자들이 언제 어디서든 다양한 컨텐츠를 생성하고 공유함에 따라, IP 주소 기반의 인터넷 전송 기술을 대체하기 위한 컨텐츠 이름을 식별자로 사용하는 컨텐츠 중심 네트워킹과 같은 새로운 네트워킹 기술들이 주목받고 있다. 그러나, 현재 CCN 기술은 사용자 이동성, 특히 이동 컨텐츠 소스의 이동성에 대해 거의 고려하지 않고 있다. 따라서, 이동 컨텐츠 소스의 이동으로 인해 컨텐츠 전달 서비스의 단절, 서비스 지연 증가와 같은 문제가 발생한다. 이러한 문제를 해결하기 위해, 터널링 기반 이동성 방안이 제안되었으나, 이동이 발생할 때마다 위치 정보 업데이트 과정이 요구된다. 따라서, 많은 제어 오버헤드가 발생하고, 핸드오프 동안 높은 패킷 손실롤 인해 재전송에 따른 서비스 지연과 전체 네트워크의 성능 저하를 문제를 야기한다. 이에, 본 논문에서는 CCN향 계층적 이동성 관리 방안을 제시하여 제어 메시지의 발생을 제한하여 핸드오프 지연을 감소시켰다. 성능 분석을 통해 제안 방안이 제어 오버헤드 감소에 따른 네트워크 확장성을 제공함으로 확인하였다.

Purpose: The present study confirms the content validity and understanding level of the questions of the Korean version of caries management by risk assessment (CAMBRA). Methods: To develop the Korean version of CAMBRA for children aged 0-5 years, a series of steps were followed: first, translation and reverse-translation processes were conducted by an expert committee. To establish content validity, CAMBRA was modified to adapt to the conditions in Korea by 17 dental hygiene professionals with a master's or a higher degree. The responses were analyzed using analysis of frequency and descriptive statistics. Content validity was verified by calculating the content validity index (CVI). The survey was administered to 64 mothers and caregivers to assess the understanding level of questions of the Korean version of CAMBRA. Results: Content validity of each of the items showed an S-CVI/AVE value of 0.79, but the content validities varied from 0.63 to 1.0. The understanding level of each question was between 3.56 and 4.46, thus showing favorable results. Conclusion: It was concluded that the test items verified for content validity were suitable for assessing caries risk for children of ages 0-5 years. This study would contribute to improving children's oral health and disease prevention by providing timely intervention.

This study was conducted to investigate the effects of saltwort, on the quality characteristics of sponge cake. In addition, we examined the commercialization potential of sponge cake containing saltwort. To accomplish this, saltwort was added to sponge cakes at concentrations of 0%, 3%, 5% and 7% and quality and sensory tests were then conducted. The 7% group had the highest water and ash content. There was no difference in the fat content between samples. The control group showed the highest protein content and the lowest specific gravity. As the content of saltwort increased, the specific gravity of the sponge cake increased. Additionally, the dough yield and loss during baking were highest, in the control group, and these values decreased as the saltwort content increased. Similarly, the volume and specific volume were highest in the control group, and these values decreased as the content of saltwort powder increased. Color measurements of the samples, revealed that the L-value decreased as the content of saltwort powder increased. Furthermore, the a-value of the saltwort powder groups was higher than that of the control group and the b-value was highest in the 7% group. There were no differences in elasticity and cohesion between samples, but chewiness and brittleness increased the content of saltwort powder increased. The results of the sensory test revealed that the color, flavor and taste scores were the highest in the 5% group. The pore size was greatest in the control group, while hardness was greatest in the 7% group, chewiness was highest in the 5% group and moistness was highest in the 5% group. Finally, the overall preference was for the 5% group.
