Fluctuation statistics of scattering strength are not only important because they impact the performance of active sonar systems, but also because they may provide insight into the major scattering process. In this article, analysis of the statistical characteristics of bottom backscattering, measured in shallow water, are presented. The slowly moving experimental sonar was operated at 30kHz to gather data over the bottom. Spatial and temporal correlation functions of the signal amplitudes were measured. The distribution function and probability of false alarm function of the detected envelope of widebeam and narrowbeam signals were measured. An attempt was made to compare the results with existing theoretical models. The result suggests that the statistical characteristics of bottom backscattering fluctuation of moving source is differ from that of fixed source.

This study was aimed to investigate the relation between codependency and mental health and to get a idea dealing with social worker's codependency for their healthy and professional caring, which is an important factor between social worker and client in social work practice. The subjects of this study consisted of 290 social workers working in social welfare facilities of Gangwon-do. The data were collected through self-reported questionnaires from Jun. to Oct., 2013. Results indicated that codependency showed over 50% of social workers were moderate-severe level and there were the significant correlation between codependency and mental health. Implications of findings of this study were discussed.

The text and diary data of many SNSs around the world are uploaded, but it does not go beyond sharing and recording the data. In general, social big data is used to identify taste and interests. However, there is a need for a system that analyzes and displays their status and information. Therefore, in this paper, the happiness diary system deals with the design of the system that can record the data of the SNS and its own diary, store them in the big data system, and express the happiness through their diary and SNS data using emotional analysis.

The Internet of Things technology is regarded as the next major technology that will be the driving force behind the fourth industrial revolution. The characteristics of entities for Internet of Things application are changing more actively and actively, requiring a more detailed approach, but existing access control technologies are designed around users, requiring access control techniques that maintain efficiency and security with less system load to apply complex and variable content. Therefore, research on role-based access controls that are appropriate for Internet of Things entities is essential. In this study, the relevant research for the study of access control of the Internet of Things entities and the RBAC and AC methods that can define the properties of the various entities within the Internet of Things.

This paper deals with mind and human nature dispute between Si-Ma guang and Han-Yu in the Northern Sung Dynasty, focused upon the "zhong-hua". The letter exchange between Si-Ma guang and Han-yu, which were the mind and human nature debate between a representative intellectually of the Confucianism and a scholar who absorbed in the Buddhism, can provide the discussion on various ideological origins that affected the development of the mind and human nature theory. Moreover, the contents of a letter from both of them can be used as an important cue to observe the discussion under what ideological foundations the mind and human nature theory could be embodied in the future and what advance it has made and what is its philosophical meaning.

플러그인 프레임워크는 기존 M&S 프레임워크에서의 문제점인 구성요소 간 높은 종속관계 및 낮은 유연성을 해결하고자 개발된 프레임워크 설계 방식으로, 프레임워크를 구성하는 컴포넌트를 플러그인으로 제공하여 구성요소의 추가 및 변경이 동적으로 이루어질 수 있게 한다. 또한 플러그인 컴포넌트간 통신을 위한 메시지 구조 정의가 실행 시점에 동적으로 결정되어, 컴포넌트 간 상호 독립적인 인터페이스를 보장해준다. 하지만, 플러그인 컴포넌트들의 조합이 이뤄진 상태에서 전체적인 메시지 연결 흐름이 원활하기 위해서는 각 컴포넌트에서 개별적으로 작성된 인터페이스에 대한 검증이 사전에 이뤄줘야 한다. 이에 본 논문에서는 XML 기반으로 작성된 객체 모델 명세서에 대한 무결성과 중복성을 검증할 수 있는 객체 모델 명세서 검증 도구에 대해 제안하고 이에 대한 설계내용을 설명하도록 한다.

This paper describes the changes in legislative rules in the U.S. House of Representatives and discusses the roles of legislative rules in public policy making. I argue that much of reform experiences in the U.S. House provide good references by which the National Assembly of the Republic of Korea may follow for its reforms. For this, I summarize primary reforms of legislative rules in the U.S. House and discuss dynamics in power distribution between committees and party leadership. These reforms are then reviewed on the basis of political stability, protection of minority rights, and legislative deliberation.

We investigated the characteristics of cognitive-behavioral response to auditory hallucinations in 27 schizophrenic patients. The results were as follows : 1) The most frequent cognitive and behavioral response was healthy cognitive one such as suppression or ignoring and increasing physiological arousal, respectively. 2) The characteristics of auditory hallucinations in good/fair copers was that if was more likely to be mild in severity and insight-oriented And increasing physiological arousal was used more frequently in good/fair copers and unhealthy cognitive-behavioral response was used more frequently in poor copers. 3) Out of 3 variables(duration, insight and severity of auditory hallucinations), the insight of auditory hallucinations was the only factor which made difference in unhealthy cognitive response. In conclusion, there were quite a diverse and unique cognitive-behavioral response to auditory hallucinations in schizophrenia.

The development of modem technology made people more aware of the importance of science education, which was followed by research on textbooks based on the new curriculum. This study compared physics textbooks that were published after the new curriculum started in 2000 and 2002 in Korea and Japan, respectively, and aimed to become a reference for further improvement of science curriculum and textbook reform. The results were as follows : 1. The number of teaching topics in Korean science textbook is greater than those in Japan. 2. In detail, the field of physics appeared to be relatively more important in Korea's textbooks, while it was the field of biology that was given more weight in textbooks in Japan. 3. The textbooks in Korea and Japan covered in more detail the concepts of 'power and energy' and 'electricity and magnetism', respectively. 4. The textbooks in Korea introduced the contents of magnetism initially, whereas their counterparts in Japan, the contents of light. As a whole, the contents of the science textbooks in Korea and Japan were very similar. However, more detailed concepts were included in Korea's textbooks, and therefore, Korea's textbooks seemed to have richer contents than Japan.

Recently, mathematical reasoning has been considered as one of the most important mathematical thinking abilities to be established in school mathematics. This study is to investigate the mathematical problems on the content of 'Set and Statement' and 'Sequences' in high school according to the four types of reasoning, namely Making Conjectures, Investigating Conjectures, Developing Arguments, and Evaluating Arguments. Those types of reasoning were reconstructed based on Johnson's six types of reasoning suggested in 2010. The content is dealt with in 'Mathematics II' textbook developed and published according to the mathematics curriculum revised in 2009. The subject of this study is nine types of textbooks and mathematical problems in the textbook are consisted of as two parts of 'general problem' and 'evaluation problem'. Finally, the results of this study can be summarized as follow: First, it is stated that students be establishing a logical justification activity, the highest reasoning activity through dealing with the 'Developing Arguments' type of problems affluently in both 'Set and Statement' and 'Sequence' chapters of Mathematics II textbook. Second, it is mentioned that students have an chance to investigate conjectures and develop logical arguments in 'Set and Statement' chapter of Mathematics II textbook. In particular, whereas they have an chance to investigate conjectures and also develop arguments in 'Statement', the 'Set' chapter is given only an opportunity of developing arguments. Third, students are offered on an opportunity of reasoning that can make conjectures and develop logical arguments in 'Sequences' chapter of Mathematics II textbook. Fourth, Mathematics II textbook are geared to do activities that could evaluate arguments while dealing with the problems relevant to 'mathematical process' included in 'general problem'.
