In recent years, as the importance of history has increased through various social issues, media, and journalists in Korea, it has led to the value of 'right history' and 'teaching history that is right. History of a country is also a core asset in a country 's cultural contents industry, and historical relics are important to prove its value. As the interest in the historical and cultural heritage has increased, researches to develop it as cultural contents by restoring it as information and communication technology such as multimedia and virtual reality are active. In this paper, we propose convergence device and contents that can provide rich experience and various learning opportunities in artifact experience through restoration of artifacts using augmented reality.

The traditional programs developed by the existing CAI technique have the fixed curricular, which make it difficult to deliver various study materials that fit the learners of various levels. In addition, a lack of the flexibility prevents from helping to make their methodology in studying uniform open minded. In order to solve these problems, we have designed and implemented a learner interface that can exclude the limits in the learners active study in solving the fractional operation. In addition to the user interface, this study includes a diagnosis module that can intellectually extract the status of learners understanding, ostensible bugs, and the associated misconceptions through the interface. The experimentation based on the learner interface and the diagnosis module shows that this system correctly diagnoses the level of learners' understanding and the errors in learning, which greatly helps the individualized study.

This case study exemplifies science classroom observation and analysis. Data from two-day classroom observation, pre- and post-instruction interviews with the teacher and instructional materials were used to analyse the features of a science classroom. A teacher's classroom practices were examined in terms of the following six categories: (1)curriculum and science content, (2)teaching and learning methods, (3) teacher' s knowledge about learners, (4)classroom environment, (5)assessment, and (6)teacher's efforts for professional development. The teacher in this case study not only improved his own classroom practices, but also took an active role in teachers' in-service education to share his practical knowledge with others. Implications that valid evaluation(or observation) frameworks of classroom practices have on teacher education and teachers' inservice education are also discussed. These evaluation frameworks should provide teachers with a vision of highly accomplished practices.

This paper studies characteristics and causes of sound, and many others by distinguishing passivity and activity of the cases of a dog vocalizing human's words. As a result of the previous cases of vocalization of human's words, the dog was able to understand characteristics of a host's voice and imitate the sound using his own vocal organs. This is the case of passive vocalization accompanied by temporary voice imitation without a function of communication. On the contrary, as a consequence of the recently reported case in which a dog vocalizes such words as "Um-ma" and "Nu-na-ya," it shows the vocalization pattern clearly distinguished from the prior cases. The given dog repeatedly vocalizes pertaining words in an active manner according to circumstances and plays a role of fundamental communication and interaction with its host. The reason why the dog can vocalize the man's words actively is determined to be that the dog has a high level of intelligence and intimacy with its host, that people react actively to its pertaining pronunciation, and so forth. The following results can be used for the study that investigates animals' sound with vocalization possibility and language learning feasibility.

Culture of Latin cultura culture derived from a translation of the original meaning of words was farming and cultivation, culture, art and later became the will of. British anthropologist E. B. Tyler book "primitive cultures, Primitive Culture" (1871) Culture in the "knowledge. Beliefs Arts. Morality. Law. Practices, including as a member of human society acquired the totality of skills or habits," he gave the definition. Culture can be seen in the human reason, of the form of action, not genetic thing by playing by learning to learn from the community and received the whole thing says. Thus, the prevalence of active cultural power of vigorous training is possible can. In this sense, our ceramic culture also reaffirming the importance of education and the reorganization is needed. Culture and what it takes to become a force larger than the act of teaching. Who supply the consumer with the culture and the sharing of feelings that can be read properly considering the skater to the consumer unless the formation of culture is impossible.

The main points of issue with the former premedical curriculum of Seoul National University College of Medicine (SNUCM) were the absence of educational objectives, decline in student motivation caused by uniform education, students' lack of a sense of belonging, and lack of humanistic education. In accordance with these issues, there were five aspects considered for the improvement of the premedical curriculum: reform based on the newly established educational objectives that corresponds with the 6-year medical school curriculum as a whole, expansion of elective courses and the development of personalized curriculum for the improvement of students' learning motives, expansion of social sciences and humanities curriculum for the development of students' capabilities as good doctors, active participation of medical professors in premedical education, and expansion of informal education and the student support program. According to the assessment done after the implementation of the reformed curriculum, premedical students were gratified with its establishment and management of multifarious liberal arts and major subjects. In preparation of the more rigorous entrance quota of the premedical school at SNUCM, there is ongoing reform of required major subjects and establishment of new subjects in the premedical curriculum in pursuit of unity with the 6-year medical curriculum. Moreover, there is ongoing development of an e-portfolio system for the association of premedical and medical education, integration of formal and informal curriculum, and reinforcement of student observation and formative evaluation. Further discussion on the assessment and betterment of premedical curriculum is needed.

Chong Myung Tang is consisted of three medicinal herbs (Acori Graminei Rhizoma, Polygalae Radix and Hoelen cum Radix). It has been used as a medicine for the purpose of learning and memory improvement. In this paper, Chong Myung Tang was screened the biological activities for Alzheimer's disease. The extract (70% ethanol) of Acari Graminei Rhizoma (1 mg/ml) showed that acetylcholinesterase (AChE) and amyloid beta ($A{\beta}$) peptide aggregation inhibitory potency are 43.1% and 76.5%, respectively. The extract of Polygalae Radix showed inhibitory activity against $A{\beta}_{1-42}$ peptide aggregation (51.5%). To predict the drug-likeness, oral absorption ability; blood-brain barrier (BBB) penetraion rate, mutagenecity and carcinogenicity; in silico screening was performed against 16 compounds in the three medicinal herbs. According to the results, all compounds have appropriate chemical structures as medicines. The six compounds in Acori Graminei Rhizoma and the five compounds in Hoelen cum Radix showed excellent oral absorption rate and BBB penetration rate. The four compounds in Polygalae Radix showed excellent oral absorption rate, but their BBB penetration was presented low rate. And, the extract of Hoelen cum Radix didn't show AChE and $A{\beta}_{1-42}$ peptide aggregation inhibitory activities in vitro. Therefore, their activity in brain may be other mechanism. According to all of the results, in silico prediction technology is convenient and effective to determine biological active compounds in medicinal herbs.

These days, the research of a sensor data management system for USN based real-time monitoring application is active thanks to the development and diffusion of sensor technology. The sensor data is rapidly changeable, continuous and massive row level data. However, end user is only interested in high level data. So, it is essential to effectively process the row level data which is changeable, continuous and massive. In this paper, we propose a sensor data management system with multi-analytical query function using OLAP and anomaly detection function using learning based classifier. In the experimental section, we show that our system is valid through the some experimental scenarios. For the this, we use a sensor data generator implemented by ourselves.

The objectives of this study have been conducted to establish effective clinical teaching program to I.C.U in terms of proper assignment of the clients for the students, proper rotation schedule, priorities in critical nursing problems and selection of the teaching and learning. We have analyzed statistically 1,850 patients who have been admitted during a period from January 1977 to October 31 1979 in Ewha Woman's University Hospital. The results are as follows: 1. The proportion to the total inpatients number was 6.5% and mortality rate was 16.3%. 2. The average hospitalized days were 5.8 days in I.C.U and the total death was occured from 1 st hospital day to 5th hospital day. So it shows a certain difficulties for clinical experiences of the senior students in I.C.U. 3. In the age of the death, 41.3% of the patients were in the 41-60 year age group. It shows highest mortality rate in socially active and productive age groups. 4. The mortality rates of the departments of the medicine was 18.7%, general surgery 18.5%, and neurosurgery 14.7%. 5. The number of patients admitted to the department of neurosystem was 30.6%, cardiovascular system 22.6%, respiratory system 11.1 ％ and urinary system 2.9%. 6. On utilizing instruments and machine for diagnosis and client's assessment in I.C.U, they have utilized everything a usual. But they never utilize angiogram and cardiac catheterization in cardiovascular system, and retroperitoneal pneumography in the urologic system. Further more we would recommend as follows 1. In consideration of the average hospital days and the date of death, the rotation program for clincal experience need to be adjusted as continuing practice program in apposite to current alternative practice program for comprehensive nursing care. 2. Socioeconomic needs for the patient's families and himself should be emphasized by the students in addition to physical needs. 3. Course content for critical care might be built up in considering of core disease centered nursing problems. 4. The diagnostic procedures and client's assessment items which could not experience in our university hospital by the students might be considered and refilled as filled trips to another hospital and visual aids.

PKI(Public Key Infrastructure)-based information certification technology has some limitations to be universally applied to mobile banking services, using smart phones, since PKI is dependent on the specific kind of web browser, Internet Explorer. OTP(One Time Password) is considered to be a substitute or complementary service of PKI, but it still shows low acceptance rate. Therefore, in this research, we analyze why OTP has not been very popular, and provide useful implications of making OTP more extensively and frequently used in the mobile environment. Perceived security of OTP was set as a higher-order construct of integrity, confidentiality, authentication, and non-repudiation. Research findings show that security awareness and perceived security of OTP is positively associated, and the relationship between perceived security and trust on OTP is statistically significant. Also, trust is positively related to intention to use OTP continuously.
