This study investigated middle and high school students' perceptions of scientific literacy in the $21^{st}$ century through the survey. Subjects were 952 students from 13 participating schools. 482 middle school students and 470 high school students, 471 male students and 481 female were involved. The survey questionnaire asked which elements they thought would be important to be scientifically literate in the $21^{st}$ century and why they chose the elements. The results showed that most of the students tended to focus on orientation, content knowledge, and mindset. A large portion of female students showed orientation was the most important element. On the other hand, male students showed that scientific knowledge as well as orientation was important.

Healthy living is an essential element of human happiness. Quality eating provides the basis for life, and the health of livestock, which provides meat and dairy products, has a direct impact on human health. In the case of calves, diarrhea is the cause of all diseases.In this paper, we use a sensor to measure calf 's biometric data to diagnose calf diarrhea. The collected biometric data is subjected to a preprocessing process for use as meaningful information. We measure calf birth history and calf biometrics. The ontology is constructed by inputting environmental information of housing and biochemistry, immunity, and measurement information of human body for disease management. We will build a knowledge base for predicting calf diarrhea by predicting calf diarrhea through logical reasoning. Predict diarrhea with the knowledge base on the name of the disease, cause, timing and symptoms of livestock diseases. These knowledge bases can be expressed as domain ontologies for parent ontology and prediction, and as a result, treatment and prevention methods can be suggested.

An Emergency Medical Technician (EMT) is a well-trained emergency responder to provide emergency medical services to the critically ill and injured patient. In various situations, EMT may destroy potential physical evidences associated with the crime scene or determination of real cause of death. This study was aimed to evaluate the educational need of forensic medicine in Korean EMT. Questionnaires were administered to 592 EMTs during March 2007. The response rate was 60.3%(357 EMTs). In questionnaires there were 13 questions regarding the general characteristics, 16 questions about roles of EMTs related with forensic circumstances, 9 questions about the education related to forensic medicine. Questionnaires rated on a 4-point Likert scale or 5-point Likert scale. Most of 119 rescue EMTs had experienced with situations related to crime or unexpected sudden death. EMTs had arrived to the scenes earlier than police and complained of some difficulties related with deficit of forensic knowledge. EMTs wanted to receive continuous educations about forensic medicine. In order to reduce dissatisfaction with EMTs roles and to improve crime scene preservations, Emergency Medical Services policies should provide regular educational curriculum by forensic pathologists and promote legal responsibilities for 119 rescue EMTs.

In the information society public libraries are situated in a rapidly changing social environment. Coming of post-printing era, expansion of knowledge, enhancement of social reflexivity, and growing flexibility of jobs, etc are bringing both crisis and opportunity to them. In order to take chances public libraries must collect materials in D/B format as well as printed and computer-file forms, and enlarge assistance to educational and research activities of residents and business firms. In addition, they must contribute to reducing information divide, increasing communal interactions, and providing leisure activities. It is required for them to develop a variety of programs and strengthen publicity among residents.

The factors contributing to the formation of an important scientific concept in South Korea and its circulation in the society are the scientific knowledge that had been already formed, matured, and established in the U.S.A, Europe and Japan and has been introduced into Korea, and the institutions that have been formed during the recent modernization in South Korea. The concept of 'genetic information' cannot be an exception in this context. The concept of genetic information is the one that has been extended and intensified by the genomics and bioinformatics formed and matured through the Human Genome Projects from the former concept of inheritance or heredity within the framework of classical and molecular genetics. The purpose of this study was to find out 'how the production structure of genetic information in South Korea has been formed', under the perspective of the conceptual, epistemic, and institutional holisticity or integratedness in the concept and knowledge production structure idealized in Western advanced nations. The discourse of genetic engineering popular in the mid 1980's in South Korea has catalyzed the development of molecular biology. However, the institutional balance that had been established for the biochemistry departments in Natural Science College and Medical College was not formed between the genetic engineering and genetics departments in South Korea. Therefore, they were unable to achieve the more integrative and macro-level disciplinary impact on life sciences, largely due to institutional lack of the capable (human) genetics departments in some leading Korean colleges of Medicine. In genomics, the cutting-edge reprogramming and restructuring of the traditional genetics in the West, South Korea has not invested, even meagerly, in the infrastructure, fund, and research and development (R & D) for the Basic or First Phase of the research trajectory in the Human Genome Project. Without a minimal Basic Phase, the genomics research and development in Korea has been running more or less for the Advanced or Second Phase. Bioinformatics has started developing in Korea under a narrow perspective which regards it as a mere sub-discipline of information technology (IT). Having developed itself in parallel with genomics, bioinformatics contains its own unique logics and contents that can be both directly and indirectly connected to the information science and technology. As a result, bioinformatics reveals a defect in respect of being synergistically integrated into genetics and life sciences in Korea. Owing to the structural problem in the production, genetic information appears to be produced in a fragmented pattern in the Korean society since its fundamental base is weak and thin. A good example of the conceptual and institutional fragmentedness is that 'the genetics of individual identification' is not a normal integrated part of the Korean genetics, but a scientific practice exercised in the departments of legal medicine in a few Medical Colleges. And the environment contributing to the production structure of genetic information in South Korea today comprises 'sangmyung gonghak'(or life engineering) discourse and non-governmental organization movement.

The study conducted research investigating their about knowledge and attitude of toward elderly aimed at 251 students in the Department of Dental Hygiene located in some areas of Gyeongbuk and Gyeongnam. The total average score concerning knowledge about the elderly was found to be 11.78 out of a full score of 25 points, and the level of physical and physiological knowledge was the highest. As regards the total average of the attitude toward the elderly, it posted at 98.58 points out of a full score of 150 points and the attitude regarding the aspect of welfare was the most positive. About toward elderly correlation of knowledge and attitude between higher knowledge score more positive was attitude about toward elderly. From the above results, it would be necessary to reinforce not only the physical and physiological aspect of the elderly but also the education in the family and social areas during the development of educational contents for the Department of Dental Hygiene in relation to the elderly. Furthermore, it is deemed imperative to improve the relationship between the younger generations and the elder generation by having students practice in institutions related to the elderly, such as institutions for senior nursing and senior welfare centers and to develop a generational community program that will provoke positive interactions between them.

This article explores the potential learning materials and methods of science practice from exhibits, and how those are presented in natural history museums as a feasible science inquiry community. The idea of science inquiry community was offered as a form of science practice that ended with science learning. A grasp of 'scientific practice to learning' is understood as a way to conceive scientific methods as well as facts and understanding knowledge. To get educational implications on the scientific practice of 'earthquake' as a socioscientific topic in the communities, we analyzed 1) the relationship between earth science curriculum and exhibits related to 'earthquake', 2) the educational goals and intentions of educators, and 3) the characteristics of the exhibits in the American Museum of Natural History and in the Smithsonian National Museum of Natural History. The results of this study showed that those museums presented the exhibits consisting of various and practical cases and events of 'earthquakes' as a socioscientific topic related to their curriculum. At the target museum, it was clearly stated that the pursuing educational goals focused on relations with local interests and socioscientific issues. For making earthquakes relevant to visitors, delivering lived experiences with raw data and interactive media was emphasized in exhibit characteristics.

Accordingly it is very important to not only develop the stack of protocol, but also try an international standardization regarding the standard protocol of VoIP. Has compared to the advanced countries having already some success in commercialization, Korea is relatively much less involved in relation to this technology and endeavors. In this regards, this paper is focused on developing a protocol stack made with encoder/decoder, the generator or the header file, syntax analyzer etc. based on the protocol grammars of Session Description Protocol supported by IETF RFC2327. For the sake of it, first describe the SDP BNF grammar based on IETF RFC2327 Augmented BNF. And then we produce the Abstract Syntax Tree, header file generator for encoding/decoding as applying the method of syntax directed to SDP protocol grammar.

A mathematics pre-service teacher T analyzed American mathematics textbooks and developed his teaching material for instruction. This study analyzed his thinking processes and results in the view of semiotics. If we regard the textbook as a sign and the unitary conversion that students should learn as an object of the sign, the interpretant of the sign is the pre-service teacher's analysis, which is conducted at the aspects of a subject matter knowledge and student understanding. T interpreted the textbook versatilely in terms of his knowledges and experiences. He developed his teaching materials as diagrams, did the diagrammatic thinking and became to have the hypostatic abstraction. This study is significant because it used semiotics for explaining T's thinking process.

The bimodal flocculation of cohesive sediments in water environments describes the aggregation and breakage process developing a bimodal floc size distribution with dense flocculi and floppy flocs. A two class population balance equation (TCPBE) was tested for simulating the bimodal flocculation by a model-data fitting analysis with two sets of experimental data (low and high turbulent flows) from 1-D flocculation-settling column tests. In contrast to the Single-Class PBE (SCPBE), the TCPBE could simulate interactions between flocculi and flocs and the flocculation mechanism by differential settling in a low turbulent flow. Also, the TCPBE could perform the same quality of simulation as the elaborate Multi-Class PBE (MCPBE), with a small number of floc size classes and differential equations. Thus, the TCPBE was proven to be the simplest model that is capable of simulating the bimodal flocculation of cohesive sediments in water environments and water, wastewater treatment systems.
