So far, it has been a general opinion that 'Hunminjeongeum' creation was made only by King Sejong himself under Jiphyeonjeon scholars' help. However, this paper stresses that 'Hunminjeongeum' was made not only by King Sejong but also by Sinmi's positive effort on King Sejong's secret order, and examines the possibility of the culture-convergence contents related to these tales as well. To reveal the ground, the method of this research was proceeded particularly focusing on following texts: Sejongsillok, Munjongsillok, Hangukbulgyojeonseo, etc. The result was as followings. 1) King Sejong's absolute trust in Sinmi, 2) Sinmi's outstanding linguistic talent in Sanskrit. 3) King Sejong's donation of Amitaba-Triad Buddha images to Bokcheonsa Temple and Sejong's granting a respecting title of 'Wugukise Hyeogakjonja' to Sinmi. 4) Sinmi's vow to educate and spread 'Hunminjeongeum' based on Buddhism, and 5) Sejo's visit Sinmi at Bokcheonsa Temple. Furthermore, if the tales related to 'Hunminjeongeum' creation are activated into a type of national or regional events or festivals without remaining simply in a story level, it would be a good way to spread the excellence of convergence K-culture with various culture contents.

Jing-Yue Jang(張景岳, 1563{\sim}1640$), a medical scalar in the late Ming(明) Dynasty wrote many books such as Leijing(類經), Zhilyilu(質疑錄) and Jingyuequanshu(景岳全書). He was also famouse for the concept of 'Warming and Recuperating(溫補)' and 'Syndrome Differantation Treatment(辨證論治)', Jingyuequanshu was written between 1636 and 1640, and first published in 1700, It can be said that the book was imported from Ming Dynasty of China to Chosun(朝鮮) Dynasty, in what is now South Korea. between 1713 and 1724 In eighteen century. the book was quoted in Euimunbogam(醫門寶鑑), Jejungshinpyun(濟衆新篇) and Magwaheotong(麻科會通). In nineteen century. the book was quoted in Euijongsonik(醫宗損益), Bangyakhappyun(方藥合編), Dongeuisusebowon (東醫壽世保元) and Euigamjungma(醫鑑重磨). The number of quoted prescription and thesis during in nineteen century. is much more than that of eighteen century, Specifically, there are thirty prescriptions of Xinfangbazhen(新方八陣) in Bangyakhappyun, and the concept of 'Nourishing Yang(扶陽)' in Euigamjungma is also based upon Jing-Yue's thesis, This fact shows that we cannot consider the medicine of the late Chosun Dynasty as an abridgement of Dongeuibogam(東醫寶鑑). It is also said that the study focusing on medical books imported from China to Korea in this period is related to understanding the medical progress in the late Chosun Dynasty and the medical intercommunication between Korea and China.

As communication technologies are developed and variety of services to mobile devices are provided, mobile users is rapidly increasing every year. However, mobile services running on wireless network environment are exposed to various security threats, such as illegal tampering, eavesdropping, and disguising identity. Accordingly, the secure mobile communications services to 3GPP were established that the standard for 3GPP-AKA specified authentication and key agreement. But in the standard, sequence number synchronization problem using false base station attack and privacy problem were discovered through related researches. In this paper, we propose an efficient authentication mechanism for enhanced privacy protection in the 3G network. We solve the sequence number synchronization existing 3GPP authentication scheme using timestamp and strengthen a privacy problem using secret token. In addition, the proposed scheme can improve the bandwidth consumption between serving network and home network and the problem of authentication data overhead for the serving network because it uses only one authentication vector.

With the use of the Internet pervasive in everyday life, people are now able to retrieve a lot of information through the web. However, exponential growth in the quantity of information on the web has brought limits to online search engines in their search performance by showing piles and piles of unwanted information. With so much unwanted information, web users nowadays need more time and efforts than in the past to search for needed information. This paper suggests a method of using query expansion in order to quickly bring wanted information to web users. Popularity based Term Weight Mensuration better performance than the TF-IDF and Simple Popularity Term Weight Mensuration to experiments without changes of search subject. When a subject changed during search, Popularity based Term Weight Mensuration's performance change is smaller than others.

The heavy metal contents and their dispersion patterns in stream water, stream sediments, land plants and aquatic larvae collected from the hydrologic system flowing via the wasted ore dump of the Moak Au-Ag mine were investigated systematically in order to evaluate the environmental impacts of the abandoned metal mine. The heavy metal content increases abruptly in the vicinity of the wasted ore dump, then attenuated with increasing distance from the mine area. Attenuating rates were stream water > stream sediments > land plants > aquatic larvae. On the other hand, the cumulative content of heavy metals was stream sediments >aquatic larvae > land plants > stream water. Each element tends to be enriched selectively according to media; Zn > Cu > Cd > Pb in stream water, Zn > Pb > Cu > Cd in stream sediments and land plants, and Zn > Cu > Pb > Cd in aquatic larvae. These results show that the degree of enrichment and dispersion of pollutant extruded from the wasted ore dump are different according to elements and media, and that the circulation system of materials of each medium is different. The heavy metals, especially Cu, Pb and Zn, of polluted downstream sediments occur in high proportions of Fe-Mn oxides and organic bounded forms, which show high potential of a secondary pollution source. The content of heavy metals and their dispersion patterns in stream sediments are different from those of ten years ago; pollution levels of heavy metals were degraded in various ranges. The Zn and Cu-polluted areas were widened whereas Fe and Pb-polluted areas were reduced. In crops collected from the farm lands in downstream area, the pepper was more concentrated in all heavy metal than rice. The pepper showed some contaminated level in Cu(9.7ppm) and Zn(149ppm), and the rice in Zn(90ppm). However, both crops showed no significant level in Cd(<0.2ppm) and Pb(<0.5ppm).

In order to investigate the origin of sulfate in rain waters and to evaluate the feasibility of using sulfur isotope method as a tracer of atmospheric pollutants, the sulfur isotopic ratio of sulfate in rain waters collected in Chonju city from October 1994 to March 1995 was monitored and was compared with those of possible sources proposed by previous works. The pH of rain waters shows an intermediate acidic range from 4.45 to 6.88 and their daily variation appears to be well correlated with to the amount of precipitation. The sulfur isotopic ratios of sulfate in rain waters show a highly restricted range from 0.0 to + 1.8‰. The ${\delta}^{34}S$ values are similar to those of soil and pine tree surrounding Chonju city, but largely deviate from those of China. D-parameter($d={\delta}D-8{\delta}^{18}O$) of rain waters varies from 9.4 to 28.8. The values indicate that the rain waters in Chonju city are originated from the rainy front of China continent. All data obtained from this study suggested that sulfate in the rain waters collected in Chonju city was mainly derived from the sulfur dioxide gas emitted by the petroleum combustion. Therefore, sulfur isotopic study for the precipitation provided an excellent tool for environmental assessment in this region and for tracing the source of atmospheric pollutants.

The purpose of this study was to investigate the quality characteristics and antioxidative effect of Dasik prepared with Lycii fructus extract(LD). LD were added in ratios (w/w) of 0(C), 5(LD1), 10(LD2), and 15%(LD3), and then proximate compositions, physicochemical properties, sensory evaluations and antioxidative effect of the Dasik were measured. LD1~LD3 samples showed higher contents of moisture, crude lipid, crude protein and crude ash as well as pH and sugar content compared to control (p<0.001). The total phenol content of LD samples (LD1, 31.5% ; LD2, 66.1% ; and LD3, 69.7%) was higher than that of control (4.71%). DPPH radical scavenging activity of LD3 showed the highest activity of 65.3%, whereas that of control (27.0%) was the lowest among samples. Additionally, ABTS radical scavenging activity of LD samples was higher than that of control (C, 38.9% ; LD1, 53.6%; LD2, 80.5% ; and LD3, 83.3%). The results of texture analysis on all samples showed that control had the highest but LD3 was the lowest (p<0.001). In sensory evaluation, the scores of appearance, flavor, taste and overall preference for LD2 was significantly higher than the samples(C, LD1, and LD2). Form the findings, this study suggests that 10% addition of LD was effective for preparation of Dasik in the aspects of the consumer acceptability and functionality.
