  • 이 연구는 학생들의 질문을 촉진하는 방안으로서의 주단위 보고서가 중학교 과학 수업에 미치는 영향을 개념 이해도, 학업 성취도, 개념도, 수업 처치에 대한 인식 측면에서 조사하였다. 중학교 1학년 211명을 통제 집단과 WR 집단으로 배치한 후, '물질의 세 가지 상태', '분자의 운동', '상태 변화와 에너지'에 대해 총 18차시 동안 수업을 실시하였으며, 이 기간 동안 학생들은 주단위 보고서를 총 6회 작성하였다. 연구 결과, 개념 이해도 검사에서는 WR 집단의 점수가 통제 집단의 점수보다 높았으며, 그 차이가 통계적으로 유의미하였다. 학습 전략에 따른 개념 이해도 점수를 비교한 결과, 피상적 전략을 사용하는 학생들의 경우 WR 집단의 점수가 통제 집단의 점수보다 높았으며, 그 차이가 통계적으로 유의미하였다. 심층적 전략을 사용하는 학생들의 경우에는 WR 집단의 점수가 통제집단의 점수보다 통계적으로 높은 경향성을 보였다. 학업 성취도 검사와 개념도 검사에서는 WR 집단의 점수가 통제 집단의 점수보다 높았고 그 차이가 통계적으로 유의미했으나, 수업 처치와 학습 전략에 따른 상호작용 효과는 유의미하지 않았다. 수업 처치에 대한 인식 검사 결과에서는 대부분의 학생들이 주단위 보고서에 대해 긍정적으로 인식하는 것으로 나타났다.

  • 버그 정정 활동은 소프트웨어 개발과 유지보수 작업에서 많은 비중을 차지하므로, 버그 정정활동에 소요되는 시간을 미리 추정할 수 있다면 소프트웨어 프로젝트 작업 계획에 큰 도움이 될 것이다. 따라서 본 연구에서는 버그 리포트를 이용하여 버그 정정 시간을 추정하는 방법을 제안한다. 본 방법에서는 먼저, 버그 리포트가 제공하는 버그 메타 필드에 k-NN 방법을 적용하여 과거 버그 리포트들을 분류한다. 다음으로, 버그 리포트의 텍스트 정보를 활용하여 과거 버그와 새로운 버그 사이의 유사도를 계산하고, 유사한 버그의 정정 시간을 활용하여 새로운 버그의 정정 시간을 추정한다. 마지막으로, 오픈 소스 프로젝트에 본 방법을 적용한 실험을 통하여 효과적으로 버그 정정 시간을 추정한다는 것을 보인다.

  • The study aims to provide some plausible explanation for why Vietnamese listed companies only stop at the level of truthful presentation of information related to accounting data through the opinion of independent auditors. The information is only at the level of compliance with the requirements of Circular 155/2015/TT-BTC in form, but in essence is sketchy. What factors affect the level of voluntary disclosure of listed companies in Vietnam? In order to identify the factors affecting voluntary information disclosure on annual reports of listed companies, the study collected data on annual reports of 122 companies listed on the stock market in Ho Chi Minh City in the period 2015-2018 and uses regression analysis methods. The research presents 8 factors affecting the level of voluntary information disclosure including: Firm size, Listed time, Profitability, Solvency, Separation of board of directors and executive director, Board size, Organizational ownership and Foreign ownership. Next, the study conducted descriptive statistical analysis correlation coefficient analysis to examine the correlation and relevance of independent variables measured by the scale ratio, testing multiple linear regression model. The results of the study show that factors listed time, profitability and organizational ownership affecting voluntary information disclosure on annual reports of listed companies in Vietnam.

  • In wireless sensor networks, adversaries may physically capture sensor nodes on the fields, and use them to launch false positive attacks (FPAs). FPAs could be conducted by injecting forged or old sensing reports, which would represent non-existent events on the fields, with the goal of disorientating the base stations and/or reducing the limited energy resources of sensor nodes on the fields. Researchers have proposed various mitigation methods against FPAs, including the statistical en-route filtering scheme (SEF). Most of these methods are based on key pre-distribution schemes and can efficiently filter injected false reports out at relay nodes through the verification of in-transit reports using the pre-distributed keys. However, their filtering power may decrease as time goes by since adversaries would attempt to capture additional nodes as many as possible. In this paper, we propose an adaptive key distribution method that could maintain the security power of SEF in WSNs under such circumstances. The proposed method makes, if necessary, BS update or re-distribute keys, which are used to endorse and verify reports, with the consideration of the filtering power and energy efficiency. Our experimental results show that the proposed method is more effective, compared to SEF, against FPAs in terms of security level and energy saving.

  • A new method for making automatic electroencephalogram(EEG) report based on the automatic quantitative interpretation of awake EEG was developed. We first analysed a. relationship between EEG reports and quantitative EEG interpretation done by a qualified electroencephalographer(EEGer) for 22 subjects. Based on the analysed relationship and usual process of report making by the EEGer, we defined all terminology necessary for EEG report and established rules for EEG report making. By the combined use of the proposed EEG report making and the method for automatic quantitative EEG interpretation presented at '90 KACC, we were able to make the automatic EEG reports which were equivalent to the EEG reports written by the EEGer. As all the procedures were programmed in a personal computer equipped with an AD (analogue-to-digital) converter, the automatic EEG reports were obtained in almost real time in usual actual EEG recording situation with only a few seconds time lag for the analysis in the computer. The proposed report making method and the quantitative EEG interpretation method will be effectively applicable to the clinical use as an assistant tool for physicians.

  • Shareholders solely depend on annual reports to make investment, credit and other decisions. Investors expect that information should be reliable, relevant, comparable, consistent and thus easy to use for decision making. But whether the importance of annual reports to all shareholders is equally significant is a question of research. Thus, this research study tries to find out the importance of reading annual reports to the investors. A questionnaire survey is conducted on investors considering thirty one general shareholders and six brokers. This research based survey finds that most of the shareholders have no knowledge about accounting or finance and they have little knowledge about capital markets due to lack of training. This study also finds that general shareholders read an annual report at least moderately except value added statement, chairman's review, director's report and rumor. This study recommends human resource should be developed through adequate training, and annual reports should provide transparent and quality information which will ultimately increase the confidence of investors.

  • As a result of broadcasters' websites, there were more reports during the typhoon Bolaven/Tembin in 2012 than in 2002 and 2003. Checking related press releases of each broadcaster on NAVER, YTN reports are 3 times more than KBS. Considering great technology progress in the Internet and smart phone user environment compared to the past, it is thought to be rather regretful in that KBS has been the supervising broadcaster over Korean disaster. As a result of daily reports, the year 2002 typhoon Rusa was reported from the date of its arrival on Korean Peninsular to 3 days, but the information required to be provided for disaster prevention before its arrival was too scarce. 2003 typhoon Maemi was reported as many times as the 2002 typhoon, but its information was provided before its arrival. This is meaningful because the information provision was intended for disaster prevention unlike the past. In 2012, the number of weather forecast broadcast on the typhoon Bolaven/Tembin increased greatly compared to 2002 and 2003. This was also determined to be due to abundant information provided by broadcasters and the Internet portal sites as a result of great progress in Korea internet industry.

  • 제1회 한국물리탐구토론대회에는 10개의 문제가 출제되었는데 본 연구에서는 이들 10개의 문제 중 ${\ulcorner}$접착 테이프(Adhesive tape)${\lrcorner}$ 문제를 해결한 5개 팀의 보고서를 비교 분석하였다. 그 결과 학생들은 접착 테이프를 갑자기 뗄때 빛이 발생하는 원인을 정전기 발생, 전자의 이동, 에너지의 변환 등으로 해석하였다. 그러나 탐구의 과정에서 확산적 사고를 가지고 창의적 아이디어를 제시한 팀은 소수에 불과하였다. 본 대회는 탐구 토론대회이므로 탐구의 과정별로 새로운 아이디어를 제안하여 결론에 이르는 창의적 탐구의 과정이 제안되어야 한다.
