Individuals and organizations in the modern society produce diverse digital objects everyday, which are not only valuable information resources at present but also will be invaluable digital heritage for the future generation. TRAC(Trustworthy Repositories Audit & Certification: Criteria & Checklist) is one of the evaluating tools against which digital archives could be assessed for their preparedness to perform the task of long-term preservation. The current study uses TRAC to assess OASIS(Online Archiving & Searching Internet Source). The results show that the web archive has a greater room for strengthening in the object management infrastructure than in organizational and technical infrastructures.

본 연구는 친족관계의 전반적 현황과 양계화 정도를 살펴봄으로써 친족관계 영역에서 변화하는 한국가족의 현주소에 대한 정보를 제공하고자 하였다. 이를 위해 본 연구는 전국의 성인남녀 1755명을 대상으로, 본인 및 배우자 부모와의 동거여부, 거주근접성, 접촉빈도를 비교함으로써 세대관계의 구조적 차원에서 양계화가 어느 정도 이루어졌는지 살펴보았다. 또한, 양계화 정도의 구체적 내용 파악을 위하여 가족의 협력 네트워크의 양상을 조사하였다. 즉 경제적, 도구적, 정서적 지원 영역에서 도움을 주고받는 대상에 대한 조사를 통하여 가족의 지원망 구성 및 활용에 있어 친족이 차지하는 비중 및 양계성의 정도를 살펴보았다. 연구 결과, 첫째, 한국가족의 세대관계의 구조적 특성은 양계화된 모습과 부계적인 모습이 혼재되어있는 것으로 나타났다. 둘째, 가족의 협력네트워크 활용의 측면에서, 한국가족은 부계친족 및 모계친족과의 상호작용이 균형적으로 이루어지는 대칭적 양계화라기보다는 비대칭적 성격의 양계화 경향을 보였다. 이것은 부계중심적으로 규범화된 친족유대의 경향이 그대로 유지되면서 동시에 실제적 필요에 의한 아내의 친족망 활용정도가 높아진데서 기인한 결과라 할 수 있다. 이러한 결과는 한국사회의 빠른 변화에도 불구하고 가족영역에서의 변화가 상당히 느리게 진행되고 있음을 반영한다.

On July 6, 2017, President Moon Jae - in attended the Hamburg G20 Summit in Hamburg, Germany, and presented the basic directions for North Korea policy through the Korean Peninsula Peace Initiative. In this paper, the Information needs of North Koreans are very strong, and the party Officials also listened to the fact that they listened to the North Korean broadcasting and watched the drama of South Korea. The broadcasting and communication sector aimed at enhancing the role of broadcasting in preparation for reunification in the light of the fact that physical contact can be excluded even in the presence of distrust of the North and the South. Therefore, it describes the cooperation plan through broadcasting against unification.

Tools for detecting cross-language clones usually compare abstract-syntax-tree representations of source code, which lacks scalability. In order to compare large source code to a practical level, we need a similarity checking technique that works on a token level basis. In this paper, we define common tokens that represent all tokens commonly used in programming languages of different paradigms. Each source code of different language is then transformed into the list of common tokens that are compared. Experimental results using exEyes show that our proposed method using common tokens is effective in detecting cross-language clones.

The purpose of this study is to develop a relationship of measuring method for the social security network and verify its validity and reliability and apply it to investigate the due to security life satisfaction. This study is based by setting general residents of Seoul in 2013 and using the stratified cluster random sampling method to analyze a total amount of 203 examples. The measuring methods for the social security network was developed through document research, conceptual definition and drafting the survey, experts' conference, preliminary inspection and original examination, verification of the validity and reliability of the survey. An experts' conference took pace to verify the validity of the survey, and 6 factors were extracted through exploratory factor analysis crime prevention design, street CCTV facilities, volunteer neighborhood patrol, local government security education, police public peace service, private security service. The conclusion are the following. Collected data was analyzed based on the aim of this study using SPSSWIN 18.0, and practice frequency analysis, F test, factor analysis, reliability analysis, correlation analysis, multiple regression analysis. First, the validity of the social security network measurement is very high. Thus, the factors constituting the social security network were found to be crime prevention design, street CCTV facilities, volunteer neighborhood patrol, local government security education, police public peace services, and private security services, and the crime prevention design factor was found to be most explanatory. Second, the reliability of the social security network measurement is very high. Thus, the correlation between the questions and the sector, the questions and the social security net was very high, and the internal consistency showed a Cronbach's${\alpha}$ value of over 0.865. Third, the establishment of a social security network had the biggest effect on people in their forties. Thus, when the crime prevention design, street CCTV facilities, local government security education, police public peace services are systematically established, the social anxiety of citizens was reduced.

Diagnostic performance of polymerase chain reaction (PCR) for detecting Dirofilaria immitis in dogs was evaluated when no gold standard test was employed. An enzyme-linked immunosorbent assay test kit (SnapTM, IDEXX, USA) with unknown parameters was also employed. The sensitivity and specificity of the PCR from two-population model were estimated by using both maximum likelihood using expectation-maximization (EM) algorithm and Bayesian method, assuming conditional independence between the two tests. A total of 266 samples, 133 samples in each trial, were randomly retrieved from the heartworm database records during the year 2002-2004 in a university animal hospital. These data originated from the test results of military dogs which were brought for routine medical check-up or testing for heartworm infection. When combined 2 trials, sensitivity and specificity of the PCR was 96.4-96.7% and 97.6-98.8% in EM and 94.4-94.8% and 97.1-98% in Bayesian. There were no statistical differences between estimates. This finding indicates that the PCR assay could be useful screening tool for detecting heartworm antigen in dogs. This study was provided further evidences that Bayesian approach is an alternative approach to draw better inference about the performance of a new diagnostic test in case when either gold test is not available.

In this paper, we analyzed the misconceptions and errors incurred during factorization learning. We also examined whether online individualization classes had a positive effect on students' mathematical achievement. The experiment was conducted for 4 weeks (16 times in total) on middle school juniors in rural areas of Gyeonggi Province, where the influence of private extra education was small. In the class, the 'Google Classroom' was used as a LMS, the video lecture was uploaded to YouTube, and the teacher interacted with the students through "Zoom" and "Facetalk". In the online class situation, students' assignments and test answers were checked in real time through 'Google Classroom', and immediate feedback was provided to the experimental class group's students. However, for the control group students, feedback was provided only to those who desired. A total of 7 achievement evaluations were conducted in the order of pre-test, formative evaluation (5 times), and post-test to confirm the change in students' ability improvement and achievement. Through the formative evaluation analysis, it was possible to grasp the types of errors and misconceptions that occured during the factorization process. Students' errors were divided into four types: theorem or definition distortion error, functional errors such as calculation, operation, and manipulation, errors that do not verify the solution, and no response. As a result of ANCOVA, the two groups did not show any difference from the 1st to 4th formative assessment. However, the 5th formative assessment and post-test showed statistically significant differences, confirming that online individualization classes contributed to improvemed achievement.
