The smallpox or chanjin(瘡疹), from Korea Dynasty when the name concretely is discussed to Joseon Dynasty, was very one of the diseases which were important. Not only the public but also the royal family could not avoid the pain which is caused by with the smallpox. Also as a scar and fear that the smallpox leave on, the smallpox was called a God(痘瘡神). As the prayer and sacrificial rites primarily could not relieve the nation and the community from a smallpox, an intellectual finally had to remind that if people considered a factor which caused the smallpox, they could cure this disease. That was Nam Hyoon(南孝溫) who rejected a goast to cause a smallpox. And the compilation of "Changjinjip(瘡疹集)" changed recognition about a smallpox. Especially, the compilation of "Changjinjip" was very important in the history of Korean medicine. Because it told what "Uibanglyuchui(醫方類聚)" the national compilation project of medicine book that King Sejong promoted leaved. The "Changjinjip(瘡疹集)" adopted two kind methods. The one was the medical history or with medical theoretic history method: arranged a various medical theory about "changjin" like "Uibanglyuchui". The other was the clinical method of presenting theories and prescriptions as causes and mutations: reformed contents of "Uibanglyuchui". In addition to special medicine book of smallpox, "Changjinjip" gave knowledge about a paradigm of "Uibanglyuchui" and methods of medical book compilation in later.

Some physical properties of Korean red ginseng extract was investigated for their changes during extraction with ethanol solution having a concentration range of 0-90% at $70-100^{\circ}C$ during 5 times of 8 hours extraction. The intrinsic viscosity was ignificantly decreased as the ethanol concentration and measuring temperature increased, while it was affected relatively less by the extraction temperature. However the effect of measuring temperature on the intrinsic viscosity was greatly reduced for the extract obtained with higher than 50% a ethanol. The turbidity and pH were also decreased as the ethanol concentration and extraction time increased.

The comparative effects of gamma irradiation an ozone treatment on the microbiological and physicochemical qualities were investigated for the improvement of hygienic quality of aloe powder and bee pollen. Gamma irradiation at 7.5~10kGy could reduce total aerobic bacteria, molds and coliforms below detection levels, but ozone treatment up to 18 ppm for 8hr was not sufficient to eliminate the microorganisms from aloe powder and bee pollen. The physicochemical properties such as fatty acid an amino acid compositions, mineral content, TBA value, barbaloin and pigment contents were not significantly changed by gamma irradiation, whereas ozone treatment caused significant changes in fatty acid composition, lipid oxidation and destruction of barbaloin and natural pigments.

The reaction of N-hydroxysuccinimide with polyacrylic acid and polymethacrylic acid gave poly(N-acryloxysuccinimide)and poly(N-methacryloxysuccinimide), whose reaction with cephradine provided polyacryloylcephradine and polymethacryloylcephradine. The activities of these polymeric drugs were investigated in terms of minimum inhibitory concentration by the common twofold dilution technique. Polyacryloylcephradine revealed excellent antibacterial activity against Staphylococcus aureus ATCC 25923, Staphylococcus aureus FDA 209P, Bacillus subtilis ATCC 6633, Bacillus licheniformis ATCC 14580, Escherishia coli BE 1186 and Salmonella typhimurium TV 119. Polymethacryloylcephradine revealed excellent Staphylococcus aureus ATCC 25923, Staphylococcus aureus FDA 209P, Bacillus subtilis ATCC 6633, Escherichia coli Be 1186 and Salmonella typhimurium TV 119.

Hunminjeongeum had 17 initial consonant letters. Among them, five consonant letters, those are ㄱ (牙音, molar sound letter), ㄴ (舌音, lingual sound letter), ㅁ(脣音, labial sound letter), ㅅ (齒音, dental sound letter), ㅇ (喉音, guttural sound letter), were served as chief consonants. There was no argument that consonant letters were made by symbolizing the shape of vocal organs during phonation of them. It could be phoniatrically explained that all of five chief consonants were morphologically symbolized from left lateral view of vocal tract during articulation. Although 'ㄱ' was known as molar sound, it was not modeled the shape of molar tooth but modeled the shape of tongue at molar teeth bearing area. The same principle applies to 'ㅅ', and it was represented the shape of upper surface of anterior tongue instead of incisor teeth. 'ㄴ' was a lingual sound and directly shaped the shape of tongue. 'ㄷ' was made by addition of a stroke 'ㅡ' meaning hard palate above 'ㄴ'. 'ㅁ' was represented the shape of lateral view of anterior mouth. 'ㅇ' was looked like shaping left lateral view of laryngopharyngeal space.

Annals of the Joseon Dynasty is a librarian that compiled the history of the Joseon Dynasty for 472 years, from Taejo to Cheoljong. The Annals of the Joseon Dynasty, National Treasure No. 151, are important documented heritages, but they are difficult to analyze due to their vast content. Therefore, rather than analyzing all the contents of the Annals of the Joseon Dynasty, it is necessary to extract and analyze important words. In this paper, we propose a method of extracting words from the main body of the Annals of the Joseon Dynasty through web crawling and analyzing the translated texts of the Annals of the Joseon Dynasty based on the data sorted according to the frequency of words. In this study, only the part of King Sejong of the Annals of the Joseon Dynasty was extracted and the importance was analyzed according to the frequency of words.

This study aims to examine the cutting traces remaining on the bracket tie beams of Sungnyemun gate, identifying the tools employed during the late Goryeo to early Joseon periods by specific processes, and deliberating on the timber shaping techniques utilized in advanced architectural construction during the late Goryeo to early Joseon eras. Through the research, it was confirmed that in the production of Sungnyemun Gate's bracket tie beams during the 14th to 15th centuries, both the timber splitting and ripsawing methods were used in conjunction. Moreover, the wood finishing process revealed the use of a plane. It can be inferred that the characteristics of the plane used during that time were not significantly different from those observed in the later period of the Joseon dynasty. The ripsawing and plane finishing techniques were evident in various parts of the bracket tie beams of Sungnyemun gate across the reigns of king Taejo and Sejong, indicating that the techniques involving ripsaw and plane were already prevalent in the late Goryeo period. Consequently, it can be inferred that the ripsawing and plane finishing techniques might have been applied in the construction of prominent government buildings in Hanyang(Seoul), including Gyeongbokgung Palace, and in the residences of royalty and nobility after the establishment of the Joseon dynasty.

The process of creating Hunminjeongeum described in Haerye version of Hunminjeongeum shows a rule of signification by which a signifiant represents a referent. In this article, I will suggest two types, the mythical and the anti-mythical, that affect the iconic relation between signifiant and referent, and consider how they are realized in Hunminjeongeum. The mythical type is shown as Yin-Yang and the Five Elements Theory and Three Elements Theory of Heaven, Earth and Man dominating the thought of intellectuals at that time. It had became mythos, that is the object of absolute belief, by connecting with the power of King at that time. It is very metaphysical and involves a kind of grand narrative. It is also the voice from the past in time and from China in space. It is reflected in Hunminjeongeum's letter system intactly. Meanwhile, the anti-mythical type also affects the creation of Icon in Hunminjeongeum. Even if Hunminjeongeum had been created from King Sejong's project, its intention seemed to be educational and practical. That is the problem of that time, not of past time, and for common class, not for ruling class. It can be considered as logos in that it had been planned and processed at a real-life situation at that time. Some arguments between King Sejong and liege Choi, Manri about the validity of Hunminjeongeum also show that the creation of Hunminjeongeum had involved the problem of critical logos. Above all, in that referents of Icons of Hunminjeongeum are the figures of human vocal organs, we can suggest that these Icons also implied an Indexicality implying actual connection between voice and body. It can be considered as a deconstrucion of metaphysics and grand narrative that had been dominated by foresaid mythical type. Hereafter, from time when Hunminjeongeum have been widely used, mythos of metaphysics and grand narrative that had dominated Hunminjeongeum have been deconstructed and Hunminjeongeum has become to realize its potential competence of pragmatic sign system for the convenience of common people. Therefore, I expect that the cultural potentiality of Hangul today can be realized by such tendency of logos incessantly deconstructing mythos, that is one direction of mythosemiosis.

The Shinmoongo (Shinmoon-drum) system is known as the last means of petition, appeal, and, denunciation during the Chosun dynasty. The purpose of this study is first to examine the system's origin and changes of its function and operation. The study further looks at several issues around the striking gong system, an alternative appealing method, and its background and transition. Introduced by King Taejong, the Shinmoongo was a kind of the press (or communication) system which was intended to deliver various cases of personal appeal, social petition, national denunciation, etc. Since the 2nd year of King Sejong, the system had been changed into the legal system which mainly to settle personal mortifying problem. Originally, the system was institutionalized for the common people who were hard to appeal their mortifying affairs to the supervisory administration. This reporting system to a superior was utilized as an institutional device to remedy abuses from 'complaint to the King near his sedan chair' and 'direct complaint out of order' during the early disordered years of Chosun dynasty. The system was often abused for the devices of private interest by illustrious officials. Meanwhile, it carried out a role of checking power abuses of provincial governors and magistrates. There were many obstacles for the common people and lowly people to turn to the means. The drum was located at the palace of capitol, less accessible for most people at the time. The petition had to be processed through several steps in written forms. The punishment on a false drummer was heavy. It inhibited any appeal concerning the superior under the rigorous caste system. The Shinmoongo system is regarded as a legitimate press system. Also, it is taken as informal or semi-official press system such as 'document to send around', 'document for agitation', 'joint petition', 'striking gong to complain', 'complaint to the King near his sedan chair', 'scream to complain', etc. Connecting together, the tools resulted in the increase of regal power and decrease of divine authority.

Annals of the Joseon Dynasty is the authentic record of the historical facts and events taken place throughout the entire period of 472 years(25 generations, 1392~1863)described in a chronological order. The tremendous volume of the records contains the factual events taken place in almost all the fields of the Joseon Dynasty ranging from politics, economy to history of the dynasty. Not only because of its affluent contents but also with the precision of its records, it was designated as the National Treasure No. 151 in1973 by the Korean government and also registered as the Memory of the World by UNESCO in October 1997.This study is to report a exhaustive investigation results on the conservation state of annals of the Joseon Dynasty, especially Mt. Jeongjoksan edition, under the storage of the Kyujanggak in order to obtain the current condition, and thereby to estimate the any deterioration of the waxed volumes in the future. According to results of the investigation, we are going to verify damage causes of annals of the Joseon Dynasty, and to consider scientific conservation methods for the permanent preservation of invaluable cultural heritage. The major problem with the preservation of annals has arisen particularly from the deterioration of the waxed volumes of the Mt. Jeongjoksan edition. In order to provide for the counter measures for this problem, we have conducted twice investigations(first :1998~1999, second : 2003) to the internal and external conditions of waxed volumes(Annals of King Taejo~Annals of King Myeongjong).The result of the investigation has indicated that the paper quality of the some of the waxed volumes (Annals of King Taejong~Annals of King Sejong) is cracked and folded and the pages are imbedded to each other due to the hardened or congealed wax on the paper. Some of the pages are even getting moldy. And in order to detect as to whether“ there has been any deterioration progressed to the waxed books in the modern storage facility of the Kyujanggak equipped with constant temperature and humidity condition, the first investigation(1998~1999) and the second investigation(2003) have recorded the values of acidity, whiteness and moisture rate of the waxed paper, reporting an observation that there has been no difference on the measuring items. This indicates that no virtual deterioration has been progressed so far to the waxed volumes preserved in the Kyujanggak. Also, except for the causes of deterioration to the paper by insects and microorganisms, the major cause for the paper damage seems to the change of moisture of the paper caused from the alteration of the temperature and humidity of the storage environment. With this understanding in mind, we have conducted an environmental investigation on the three selected points of the storage in the aspects of the temperature, humidity, air current, $CO_2$,HCHO, and $SO_2$.It has been observed that the temperature stood at $16.9^{\circ}C~20.2^{\circ}C$ and the humidity was stable between 53%~56% during the period of the investigation. The concentration of the carbon monoxide and carbon dioxide of the storage were very similar to those in the air. These data lead to presume that there is no problem in the aspect of carbon oxidization. But the concentration of sulfur dioxide, hydrogen sulfide and formaldehyde of the storage were detected a little higher than those of standard. Therefore, we consider that it is necessary to ventilate the internal air of the store room by means of operating air purification devices.
