This study is to investigate the effects of a mathematics history lecture on elementary students' math learning. Pre- and post-tests were done for 33 6th grade students before and after 3-units of mathematics history lecture by a mathematician. The results show that the lecture improved students' interests and confidence on math. Especially, the tests present a positive change in students' attitudes on math and results in an increased curiosity on and willingness to study math. This study shows a consistent result with previous studies of teaming effects of introducing mathematics history in math. This study also highlights that even 3-units of math history lecture can significantly improve students' attitude and belief on math learning. Given the positive effects of math history lecture on students' math loaming, it is implicated that math history be included in the formal elementary math curriculum and more participation of math history experts in math.learning processes is needed.

As the interest in sensor networks has been increased recently, researches have been performed in many areas using sensor networks. In this paper, we propose and implement a lecture room control system based on a sensor network. It is possible to give an efficient lecture by collecting lecturers' lecture history information through the sensor network and controlling a PC, a beam projector, lights, etc. in a lecture room appropriately using the information. We construct a sensor network and perform experiments so that the proposed lecture room control system performs efficiently. Through the experiments, we obtained the optimal message generation period of the sensor node in a lecture room and the optimal number of sensor nodes deployed in a lecture room to communicate without any trouble between sensor nodes.

A very unique case is found in the architectural remains related to the north and south square-platform at the lecture hall site of Hwangnyongsa, that of Anyangsa, and the estimated lecture hall site of Beopsusa as they are not observed in the other lecture halls. The platform has been discovered at only those three Buddhist temples from Goryeo, and its case has not been found in ancient Buddhist temples of China and Japan. This study thus set out to investigate the north and south square-platform at lecture hall sites by examining in details its architectural remains at the three Buddhist temples and reviewing the Buddhist literature about the lecture halls of ancient Buddhist temples. Based on the findings, it was estimated that the architectural remains of north and south square-platform at the lecture hall sites of Buddhist temples were those of platform for Buddhist sermons or those of high chair platform. While the north square-platform involved the remains of north high chair for the Lecturer that gave lectures on the Buddhist scriptures, the south one did those of south high chair for the Reader who recited the Buddhist scriptures.

Simgok Seowon is the commemorative shrine and academy established for scholar Jo Gwangjo (pen name : Jeongam). The shrine (sangnyangsik) and the east and west dormitories (Dongjae and Seojae) were built in 1636. The lecture hall, Imsimnu Pavilion, Sananggak and Munhyanggak buildings were built successively. Simgok Seowon is the only one that survived through the abolishment of seowon ordered by Regent Heungseon in the 19th century. The original seowon was renowned as a representative example showing the typical lecture hall in front and dormitory at the back (jeondanghujae) layout of the Giho School built in 1650. Two archaeological excavations were conducted in the lecture hall courtyard in 2004 and 2007~2008, which prompted debates the position of the dormitories in respect to the lecture hall, whether the dormitories should be placed in front, or at the back of the lecture hall. Simgok Seowon had been long known as a representative example of the lecture hall in front layout, but the excavations revealed contrasting evidence, suggesting the possibility for a dormitories in front layout. Recent studies and evidence show that the architecture of Simgok Seowon can be grouped into three phases. The first phase was when the shrine and both dormitories were built to the rear of the lecture hall, the second phase was when the lecture hall, Imsimnu Pavilion, Sananggak and Munhyanggak buildings were built, and lastly the third phase when the east, west dormitories were reconstructed in front of the lecture hall. The large scale construction of Simgok Seowon is related to the education based management of the academy by Doam Yi Jae, and the 17~18th century remains confirmed from the archaeological excavations are evidence of this. Remains for Imsimnu Pavilion, Sananggak, and Munhyanggak buildings have yet to be confirmed, and spaces to the south and east of the seowon are unidentified. Therefore, it is necessary to conduct investigations and research for the unexcavated spaces of the seowon, to conduct in-depth studies and for the effective adaptive re-use of the seowon.

Jeongrimsaji as temple remains of Baekje Sabi period, its re-excavation has been carried three times in full scale. As a result, the buildings in left and right of lecture hall was largely identified in 3 forms. First, layout of small buildings in left and right of lecture hall. Second, layput of corridor in left and right of lecture hall. Third, layout of construction site in the north of corridor in left and right of lecture hall. Above second is included into remains of Gorye, the third is included into remains of Baekje - the remains were almost ruined then. The first form and third form in above is different each other in size of buildings, form of layout, and location. It is important to investigate these points: the time of constructing the buildings; what position have the use and function of the buildings in the temple? ; transition process of layout of the Buddhist temple. In this context, of temple remains in Baekje during the 5~7th century, the cases where construction sites in left and right of lecture hall and construction site in the north of corridor are identified, have been reviewed. Based on this review, the use and function of buildings, their transition process were investigated. The survey results show that small buildings in left and right of lecture hall existed in the middle and later period of the 6th century. During the later 6th century ~ the 7th century, construction site in narrow and long square shape was located in left and right of lecture hall instead of small buildings in the north of corridor. Therefore, it is identified that the aforementioned thing is earlier stage and the latter thing is later stage.

This paper studied the origin of Myeongnyundang(明倫堂), the common name of the main lecture halls at confucian schools in ancient China. Through an extensive investigation of local chronicles, biographies, decrees and construction essays, it found the first Myeongnyundang were titled on the main hall of a local school in the early Southern Song(南宋) period, and it might become the most popular name due to Zhuxi (朱熹), a famous confucian scholar in the Southern Song dynasty. In Yuan(元) period, it almost become the fixed name for the main lecture hall at local confucian schools, and even the official government documents began to use it as a common noun since the beginning of Ming(明) dynasty.

In July 2008, I obtained a copy of "Hanbang Eihak Gangseupseo" through Uibangseowon. It was recorded that the book was compiled by Seong Ju-bong and reviewed by Ji Seok-young. According to previous studies, this book was the lecture book that was used in teaching Traditional Korean Medicine in Daejeon, Chungcheongnam-do. This book gave insight to the system and curriculum of the school for Traditional Korean Medicine in Daejeon, Chungcheongnam-do. It also exhibited the academic characteristics of Traditional Korean Medicine in the Period of Japanese Occupation and the medical viewpoint of Seong Ju-bong. The summary is as follows: First, an independent School for Traditional Korean Medicine was run in Daejeon, Chungcheongnam-do, with reasonable curriculums and systematic textbooks. Second, the medical viewpoint and treatment methods of Huang Yuan-Yu of Qing Dynasty was actively introduced. Then it was reorganized for the society and stimulated the progress of Traditional Korean Medicine. Third, while absorbing Chinese Medicine, it still inherited our heritage of Traditional Korean Medicine Especially, Seong Ju-bong's original opinions and clinical experiences are shown in surgery, gynecology and pediatrics. Fourth, in a break from the past, when Chinese culture could not be introduced due to diplomatic problems between Joseon and Qing, efforts were made to overcome limitations of lagging behind by adopting and educating Warm Disease study. Fifth, while working side by side with Ji Seok-young who introduced the modern Western Medicine through vaccination, it still searched for a traditional Korean medical treatment for chickenpox. I hope that the report of my findings through reading "Eihak Gangseupseo" could make up for the fact that the medical history during the colonial period is scarce.

Sewon was a new type of private academy established by a class landed Confucian scholars known as sarim. During Joseon dynasty, sewon had dual functions as a shrine and a place of learning. The site plan of seowon appeared mainly two types of site plan according to the indications of the age and school. This paper was done to analyze the site plan and construction history of Simgok seowon with historical materials and excavation investigation result. Simgok seowon is dedicated to Jo Gwang-jo(1482~1519). This private Confucian academy was founded in 1605 as a small shrine, which was destroyed in 1636. Thereafter, when the shrine received a royal warrant naming as Simgok seowon in 1650, the new site for the seowon was chosen, which is currently located in Gyeonggi-do Yongin-si Sanghyeon-ri 203. Since then, buildings of Simgok seowon was constructed and repaired couple of times. Through the investigation, it was found that the site plan of Simgok seowon was originally a type of 'jeonjaehudang', that is, dormitory building between the lecture hall and the outer gate, or dormitory building is in front and lecture hall is in behind.

Seowon(書院) is a representing institution in Choseon Dynasty not only educationally but also politically and economically. Due to the artificial crackdown by Daewon-gun in 1871 and destruction by wars, it is difficult to restore and interpret the Seowon accurately at present. It is well known that the 'Basic Form' of the Seowon consists of an inner court, enclosed by the rear gangdang (lecture hall), dongseo-jae (east and west dormitory), and the front munlu (gate pavilion or upper story bower for relaxation), represented by so called 'front-dormitory rear-lecture-hall type', that is, 'jeonjae hudang(前齋後堂) type'. However, it is overlooked that this Basic Form is a product of Youngnam School located only in Youngnam area. A different form, of 'front-lecture-hall rear-dormitory type', or 'jeonndang hujae(前堂後齋) type' is located only in Gyeonggi, Hoseo and Honam area. It has been wrongly analyzed that the type is a result of the later period, emphasizing the memorial service rather than the lecture itself, and worshipping loyalists than Confucian scholars. Analysis encompassing each Seowon architecture has been mistakenly made by historians as "deterioration" of the original educational purpose of the Seowon from the early period to the later period. This paper raises the fact that the form of jeondang hujae type has been established since the early period of Seowon in the 16th Century. It has a unique order of space itself. Here, the lecture hall faces toward sadang (shrine). The inner court, enclosed by east and west jae and the lecture hall, becomes the outer yard of the shrine, and as a result two main spaces of the shrine and lecture area is merged into one. While the munlu of the basic type encloses the inner court of the main area, the munlu of jeondang hujae type is located at the vicinity area. This paper reinterprets the jeondang hujae type not as a form coming out of degenerated period but as a type that belongs to a different Confucian school, the area of Kiho, and concludes that the Seowon is a product of political struggles between the two schools and of the local economical situation. Each school has maintained his own type of form, therefore the remaining Kiho Seowon architecture can be reevaluated.
