In Logic Bomb, the conditions of branch statements that trigger malicious behavior cannot be detected in advance, making Android malicious app analysis difficult. Various studies have been conducted to detect potentially suspicious branch statements that can be logic bombs and triggers, but suspicious branch statements cannot be properly detected in apps that contain information determined at runtime, such as reflection. In this paper, we propose a tool that can detect suspicious branch statements even when reflection is used in Android apps. It works through recording app execution logs and analyzing the recorded log). The proposed tool can check the relationship between the called method and the branch statement by recording and analyzing the user-defined methods, Java APIs called and method information called through reflection, and branch information in the log while the Android app is running. Experimental results show that suspicious branch statements can be detected even in apps where reflection is used.

In this paper, we propose a proactive inference method of finding suspicious domains. Our method detects potential malicious domains from the seed domain information extracted from the TLD Zone files and WHOIS information. The inference process follows the three steps: searching the candidate domains, machine learning, and generating a suspicious domain pool. In the first step, we search the TLD Zone files and build a candidate domain set which has the same name server information with the seed domain. The next step clusters the candidate domains by the similarity of the WHOIS information. The final step in the inference process finds the seed domain's cluster, and make the cluster as a suspicious domain set. In experiments, we used .COM and .NET TLD Zone files, and tested 10 seed domains selected by our analysts. The experimental results show that our proposed method finds 55 suspicious domains and 52 true positives. F1 scores 0.91, and precision is 0.95 We hope our proposal will contribute to the further proactive malicious domain blacklisting research.

Purpose: The purpose of this study was to investigate factors associated with suspicious developmental delay in infants and early childhood. Methods: Participants were 133 infants, aged from birth to 6 years old and their mothers, who were being seen at 16 Public health centers in B city. Korean Denver II was used to test infant development. ${\chi}^2$-test, Fisher's exact test and multiple logistic regression were used with SPSS 19.0 to analyze data. Results: Of participant infants, 7.5% were below the 3rd percentile for the weight percentile, 8.4% is a weight curve that crosses more than 2 percentile lines on the growth charts after previous achievement, and 9.8% had suspicious developmental delay according to Korean Denver II. Further the predictive factors related to suspicious development delay in the children were decrease of weight percentile (Odds Ratio [OR]=6.69, Confidence Interval [CI])=1.22-36.45), low economic state (OR=6.26, CI=1.50-26.00), and development delay perceived by their mothers (OR=4.99, CI=1.24-20.06). Conclusion: It is necessary to build a government level system to follow management of development of infants and children from the time of birth. Especially, it is necessary to develop a program for children in low income families.

Spectrum-based fault localization (SFL) method assigns a suspicious ratio. The statement is strongly affected by a failed test case compared to a passed test case. A failed test case assigns a suspicious ratio while a passed test case reduces some parts of assigned suspicious ratio. In the absence of a failed test case, it is impossible to localize the fault. Thus, a failed test case is very important for fault localization. However, spectrum-based fault localization has difficulty in reflecting the unique characteristics of a failed test because a failed test case and a passed test case are input at the same time to calculate a suspicious ratio. This paper supplements for this limitation and suggests a test case grouping method for more accurate fault localization. In addition, this paper suggested a filtering method considering test efficiency and verified the effectiveness by applying 65 algorithms. In 90 % of whole methods, the accuracy was improved by 13% and the effectiveness was improved by 72% based on EXAM score.

Background: Echocardiography is rapidly establishing itself as the primary diagnostic technique for investigation of children with heart diseases, and referrals are increasing to the pediatric cardiology clinic for investigation. However, because there is a lack of analyzed data on the patients referred to the pediatric cardiology clinics, we have proceeded to compare and analyze their characteristics to provide basic data base. Methods: From Oct. 1, 1998 to Jul. 10, 1999, total 443 cases referred to the pediatric cardiology clinic of Yeungnam University Hospital were studied retrospectively by medical records, chest X-ray, EKG and echocardiography, etc. Results: The results were as follows. 1. The proportion of male was 61.0%(261 cases) and that of female was 39.0%(67 cases). The ratio of male to female was 1.6:1. The proportion infants less than 1 year-old was 62.6% (26R cases) of all patients. 2. Cardiac murmur was present in 248 cases(57.9%), which was the most common case of referral ed to the pediatric cardiology clinic. The impression at referral was more congenital heart disease(70.6%) than acquired heart disease(17.8%) and arrhythmia01.6%). 3. The final diagnosis was as follows : congenital heart disease was present in 212 cases(49.5%), acquired heart disease, 59 cases(13.9%); arrhythmia. 13 cases(3.0%); normal heart. 144 cases(33.6%). Conclusion: Among the patients referred to pediatric cardiology clinic, 33.6%(144 cases) had normal hearts and why these patients were referred may be possibly due to more dependence on echocardiography than on auscultation instruction. Therefore, clinical and auscultatory skill should be emphasized to minimize dependence on expensive echocardiography for evaluation of pediatric heart disease.

인터넷의 급속한 보급으로 인하여 많은 웹 서버들이 생겨나게 되었다. 이러한 웹 서버의 관리와 운영에 모니터링 시스템이 많이 쓰이고 있다. 대부분의 모니터링 시스템들은 각 서버의 자원 활용 상태나 서비스의 가용성에 대한 정보를 제공하고 있지만 웹 서버의 또 다른 문제인 해킹에 대한 정보는 제공되지 않고 있다. 이것은 해킹에 대한 예방이 기존의 보안 솔루션으로 가능했기 때문인데, 요즘 화두가 되고 있는 웹 해킹에 대해서는 기존의 보안 솔루션으로 예방이 어려워지고 있다. 이러한 문제점을 해결하기 위해 본 논문에서는 웹 애플리케이션의 취약성에 대해 알려주고 웹 해킹 시도로 의심되는 행위에 대한 로그를 제공해 주는 모니터링 시스템을 구현한다. 구체적으로 웹 애플리케이션 언어들 중에서 많이 쓰이는 PHP에 대한 웹 해킹 취약성에 대하여 조사하여 웹 애플리케이션의 취약성 정보를 제공해 주고 웹 해킹 의심로그를 생성해 주는 시스템을 구현한다. 구현된 시스템은 관리되는 서버의 웹 애플리케이션의 취약성을 알 수 있고 웹 해킹 시도로 의심되는 로그를 남겨줌으로써 웹 서버 관리자에게 웹 해킹에 대한 보안성 향상에 필요한 정보를 제공해주는 이점이 있다.

This paper focused on studies of Noneo Jilseo("論語疾書") written by Lee Ik, also known as his honored name, Seong Ho(星湖). Seong Ho(星湖) also had left 10 types of exegetical commentary other than Noneo Jilseo("論語疾書"). The reason for choosing Noneo Jilseo("論語疾書") was that the teachings of Kongzi(孔子) were contained in Noneo("論語"). Also when we understand the Analects of Kongzi(孔子) correctly, we will be able to understand other Confucian Canons accordingly. Seong Ho(星湖) recommended Zhuzi(朱子) pronounced Noneo Jipju ("論語集註") as a critical commentary on the Analects. That is because there are no writings that had considered pupils' opinions and all of the various situations as much as Noneo Jipju ("論語集註"). For this reason, Noneo Jipju ("論語集註") could play a role as an excellent text. However, it is not just quality of the book that matters. While reading the main body, there is an author's comment, saying "For now, I write down my skeptical point of view." With this short note, the author expressed that "Collected Annotation on the Analects" was not necessarily the best teaching. This is the consequence of 'doubt.' We should be skeptical about the Analects of Confucius. That is not to say that the Analects are unconditionally bad. Seong Ho(星湖) expounded that the beginning students should regard Noneo Jilseo("論語疾書") as their textbook, but do not cling only to the disciplines elucidated in the book. Seong Ho(星湖) had written Noneo Jilseo("論語疾書") in order to help people to understand Confucius correctly. Although this book was written during his early professional years, Seong Ho(星湖) had grasped the essence of teaching precisely. Then, what is the essence? That is 'Doubt.' Innate factors therein can be correctly understood through 'Doubt.' In this context, Seong Ho(星湖) had made such comment as "For now, I write down my skeptical point of view." To understand the opinions of Confucius correctly, this process that being doubtful about the text is necessary. The Analects of Confucius are just similar to a coded message. To know accurately about the code, it is necessary to start from 'Doubt' at the first. Such a "Doubt" shall be a key to decrypt the coded messages further.
