Purpose: In Korea, traffic information is collected in real time as part of Intelligent Transportation System to enhance efficiency of road operation. However, traffic information based on real-time data is different from the traffic situation the driver will experience. Method: In this study, forecasts were made for future highway traffic by day and time period by adjusting the Archived data reference days to 3, 5 and 10 days based on existing traffic Archived data. Results: Fewer days of reference in the past showed smaller errors. The prediction of Monday based on five past histories showed greater errors than the 10 past histories, as the traffic flow on the sixth Monday of 2016 was somewhat different from the usual holiday. Conclution: This study shows that less of the reference days of the past history when estimating traffic volume, the more accurate the data of the traffic history of the event can be used on special days.

Real time location system was development for safety management at road and bridge maintenance field. The system can check the real-time location detection, movement history, behavior of a number of laborers. The system consisted of a Bluetooth and ZigBee that uses low-power. It had a very large error that the previous method for the position recognition by triangulation using the RSSI. Because This study proposed a new distance measurement and correction scheme using RSSI and accelerometer. It was evaluated in the maintenance field. A development system were evaluated in the field, the results are shown an error between 0.2 m and 0.4 m. And through the acceleration of history it was confirmed by determining possible to determine the safety situation of the laborers.
The purpose of this paper is to report a newly discovered book whose title is Ikkam (翼鑑) and prepare for a full-scale study. The book, Ikkam, has a variety of contexts in which it seems to be written by Park Ji-won. First, 'Sanin' in 'Yeonam-Sanin' is consistent with the behaviors of Yeonam Park Ji-won who lived in hiding in the Yeonam valley in 1777. In addition, many statements written in the introduction, such as "as we stick to the old things, we do not know a makeshift", "we are well versed in changes" and "many soldiers are not always good" remind us of other writings of Park Ji-won. Moreover, he writes the statements using antithesis. It is the force of writing style of a literary person who is not engaged in medical service. In addition, he puts six qi in the introduction, but it is not as sophisticated as Jejungsinpyeon (濟衆新編). It suggests that this book may be published earlier than Jejungsinpyeon. When comparing Ikkam with Euimunbogam (醫門寶鑑) and Jejungsinpyeon, it seems common to place six qi in the introduction at the time. In addition, through this book, we find that Park Ji-won known as a writer of Geumryosocho (金蓼小抄) has fairly much knowledge in the medicine. We can estimate his passion and depth about the medicine through a longing for a new medical book shown in the introduction of Geumryosocho. However, various approaches to similar disease symptoms shown in the introduction help us to recognize his true qualities in the medicine. In addition, like other experience prescriptions, this book excludes prescriptions using medicinal herbs with toxicity or rare medicinal herbs in the situation with a limited supply of them in remote areas but includes prescriptions which are widely used. It shows that experience prescriptions in the Joseon Dynasty are effective to specifically identify medicinal herbs and prescriptions which are widely used in Korea. These values cannot be compensated by Donguibogam (東醫寶鑑) which has an infinite value.
No.87 Sogong-dong where is the Chosun hotel stand. There was the Nambeol-gung(south ern royal villa) which had been a reception hall for enboys of the toadied country before Hwangudan圜丘壇 being set up in the year 1897. The site of the Nambeol-gung was Gyeongjeong慶貞 princess's a lot for house in the early 15th century. But after princess's death, it occurred property dispute between her son and four daughters. As a result of the dispute, a lot and a house of all the princess's properties reverted to the government. At reverted this lot was established a big royal villa in the year 1583 and that royal villa was granted to Uian prince. The villa reverted to the government again when the Uian義安 prince was dead in 12 years old by an epidemic. After the Imjin Invasion壬辰倭亂, another houses and buildings got to be role as a palace because of all the palace in the capital was burnt down to ashes. Among others Nambeol-gung was brought into play as the royal audience chamber. As well as, the villa became brought out role as a reception hall for enboys of the toadied country instead of a damaged reception hall the Taepyong-gwan太平館. In period when the envoy didn't come, the Nambeol-gung was used to extraordinary office of government like Dogam都監. This situation is to mean that the Nambeol-gung is not the royal villa any more. Because of the Nambeol-gung was built as a royal villa, that spaces were composited like space of house and palace. But this spatial composition and spatial name were not fit to hold a ceremony of government office. After all, Nambeol-gung was used change only the spatial name conform to ceremony of office keep up the spatial composition.
Modern museums that started from 17th century in Europe have played a role of storage for collections of the upper class as a form of private museum. Since 18th century the publicity has been more emphasized in the society of Europe and there became a public museum that serves as a institution for social education. In addition to this, the mass production that began with the Industrial Revolution relieved the working hour of the public and they started to spend their more time for visiting museums to have social education. In korea there constructed a lot of public museums after economic development and people experienced the social education and the cultural events. However, there raised questions on security issue regarding relic because of growing number of visitors to the museums. Due to this, the museums asked a surveillance system for their relic. But the museums don't have enough research on this nor understanding the current situation. Because the relic in museums of history has a money value, the anti-theft system is more focussed. In addition to the direct surveillance system with staff or closed-circuit television(CCTV), the indirected system with visitor's mutual surveillance in conjunction with spatial structure has to be researched. This study is to understand the relationship between surveillance system and spatial structure with reference to korea's national and public museum of history. With the results of the research, the study provides a planning guideline to the museum architecture to prevent security problem.
Although milk, which is a representative western food, has a more than 100-year history in Korea, the preference is controversial. This study examined the milk history of Choseon in 1884~1938. This period was divided into 4 periods regarding the westerner's records and advertisements. Westerners who visited Choseon in 1884~1895 ($1^{st}$ period) recorded the eating habits of Choseon,i.e., no milk consumed, even in insufficient food situation. Among the westerners, medical missionaries began to show or/and recommend condensed milk for sick children. In 1896~1909 ($2^{nd}$ period) newspapers, general shops in Hanseong for westerners showed advertisements of dairy products. In the 1900s, condensed and raw milk were advertised through newspapers. Domestic ranching systems to produce raw milk were established at that time mainly by Japanese. In the 1910s ($3^{rd}$ period), raw milk and condensed milk were advertised in newspapers. Since the mid-1920s ($4^{th}$ period), dairy products were bisected into condensed and powdered (dried) milk. Moreover, many Japanese manufacturers appeared in the advertisement in the 1920s. These results suggest that milk has been recognized as a symbol of an enlightenment food in Korea since the late 1900s, but the old negative wisdom, unfamiliar taste, and high price of milk at that time limited its appeal.
The purpose of this study is to make out a history of the coastline deformation with annual aerial photos of the target area and to suggest an efficient method for interpreting the coastline deformation. First, there were difficulties in obtaining annual aerial photos of an identical area as well as collecting periodical datum because of too much change of the real area during more than 27 years. Besides the past aerial photo is inferior to the latest one in quality. So there is nothing but to exclude an accuracy evaluation of the ortho photo. Taken into account the extent of the coastline change for 27 years is more than 10M and the all errors of the ortho image is included in this extent, both an accuracy and an error are ignored. The result of this study show that the coastline in the sea area of Namhangjin maintain advanced forward the ocean and keeps on moving with maintaining fairly wider shape of balance beach. Also The coastline deformation off l㎞ from the estuary is greatly irregular, which means the erosion of the sea in this area is in progress. The latest data being the aerial photo in 1996, it is difficult to find out the current conditions of a coastal erosion. However, considered the construction of a breakwater in Anmok Harbor is going on, the beach erosion becomes more accelerative recently. The aerial photos of the present Namhangjin's situation will make it possible to understand the history of the coastline change more accurately.
The topic in this thesis stems from the current education situation that represses learners' freedom by excessive instruction and compulsory institution, in spite of the education helping learners free from inner prejudice as one of its chief aims. In this thesis, to discuss with an educational aspect, I call the learners' freedom in the learning process 'freedom-in-process' and the learners' freedom as the result of learning 'freedom-as-result'. Through this discussion, the conclusions are as follows; First, learners who enjoy freedom-in-process get to obtain freedom-as-result in mathematics education. Second, freedom-in-process and freedom-as-result appear repeatedly in the process of looking for and gaining structures. Freedom-in-process and freedom-as-result are both faces of coin, like seed and fruit which are related mutually and fertilized each other. For this purpose, Mathematics teacher must have awareness of the value of freedom, cherish the freedom, and enjoy it with his students.
Objective : Zhao Xian-Ke(趙獻可) was a doctor in the Ming(明) Dynasty. His representing book is "Yiguan(醫貫)". It is considered as a requirement to study the Mingmen academy(命門學說). "Xuanyuanfulun(玄元膚論)", volume I of "Yiguan" intensively mentions his medical viewpoint. The study investigates Zhao's medical perspectives by studying "Xuanyuanfulun". Method : "Xuanyuanfulun" is translated. "Yiguan" published by Chinese Medicine(中國中醫藥) Publish was used as basis. "Yiguan" published by Xuexiao(學苑) Publish was used for reference. I checked and researched for several parts shown in "Suwen(素問)" and "Lingshu(靈樞)". I researched for 'Master(主)' of a human being. Result : 1. 'Master' of a human being is intangible Huo(火) in Mingmen. 2. It may be hard for me to assent to the opinion of Zhao Xian-Ke that the inferior twelve organs should be regarded as inferior eleven organs naturally. 3. Yinyang(陰陽) is to relatively cope with a situation and its wonders are within Wu(無). 4. The study emphasizes the importance of Yang, Huo and Qi(氣). 5. The study separates the date (year, month, date and time) into yin and yang and the causes of an illness are found based on the concept and its treatment shall be performed. 6. Among Wuxing(五行), Shui(水) and Huo are especially important. 7. There are intangible Shenshui(腎水) and intangible Xianghuo(相火) separately from the Shui and huo of Xinshen(心腎). Conclusion : The medical philosophy of Zhao Xian-Ke has been deeper. In addition, it will provide much help while understanding volumes 2 - 6 of "Yiguan" and apply to the clinical tests. I think it is not the problem, which is the right meaning of 'Master' in the "Xin is monarch of the organs" of "Suwen Linglanmidianlun(靈蘭秘典論)" or 'Master' that concerned by Zhao Xian-Ke, but it is just the different sight of the human being.
This study is to analyse the transformation process of spatial structure of traditional small city structure in Jeollabuk-Do in the process of modern urbanization between 19th century and the year 2000. The small cities, IM-PI, YONG-AN, YEO-SAN, OK-GOO, GO-SAN, MU-JANG, GUM-MA, GO-BU, which have been local administrative center in CHO-SUN dynasty, have role of local administrative center of subdivision of country-myon, except OK-GOO. The method of this study is to investigate the transformation process of spatial structural elements of with the actual field surveys, the analysis of Gunhyun map made in 1872, land registration maps in 1910s and 2000, and various topological maps. The elements of analysis are the topological site and geographical situation conditions, the urbanized areas, the street systems, the function of streets, the focal points of urban land use, the land use systems, and the location of major facilities such as administration facilities, markets, bus terminals. The analytical point of view and the results are as follows. There is strong relationship between the transformation of internal matrix route system and the growth pattern of urbanized areas, Especially on the contrary to the matrix route with East-West direction which has the role of checking the growth of urbanized area, the South-North direction route acts as the leading line of the growth. The focal points structure of urban land use shows transformation process from the point of central space of administrative district in front of Nae-A, to the access point to administrative district or to the access point to housing and neighborhood commercial area. From the point of functional area structure and major facilities location, line-type commercial area is developed along the line of central axis route and access route to administrative district. Especially direction of the growth of commercial area is strongly connected with the interrelationship between the study area and its neighboring cities. Pattern of commercial district development is varied with the direction of matrix route. That is, commercial district, which shows one side development pattern along the East-West direction route, is developed on both sides of street along the South-North direction route.
