고려 충렬왕때의 대표적 천문학자 오윤부는 풍수지리와 점술로도 이름을 펼쳤다. 오윤부는 매일밤 하늘을 관측하여 천문도도 직접 만들었으며 임금의 신임을 받아 고려의 사일 즉 토지의 신에게 제사지내는 날까지 바꾸어 놓은 사람이다. 또 천재지변이 있을때마다 그의 예언이 적중하여 점술가로 명성을 펼치게 되자 원나라의 세조도 그를 불러 점을 쳐서 그의 이름은 더욱 고명해졌다고 한다.

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.

Sowing time of barley after cultivation of rice has frequently been delayed because of rainfall or some other reasons by rice cultivation. Partial tillage direct grain seeder with eight row, which had been developed for rice sowing and showed many advantages in wet field, were tested for barley sowing. After flooding during $2{\sim}3days$, plots were designed to make wet condition. Three sowing methods were tested; high ridged broadcasting, plat drill seeding and partial tillage direct grain seeding. It were impossible to sow properly even in 27% of soil water content by high ridged broadcasting, plat drill seeding but could be possible to sow normally by partial tillage direct grain seeder in 42% of soil water content as good as in 27% of soil water content. Initial growth condition after sowing in plots of partial tillage direct grain seeder were normal even in plots sown in more than 50% of soil water content. No. of spike, which was $508/m^2$, in plot of partial tillage direct grain seeder sowed at 30% soil water content was better than plat drill seeding, $404/m^2$. Yield and yield components of plot of partial tillage direct grain seeder, were higher than plot sowed by plat drill seeder in same soil water content. Partial tillage direct grain seeding can be a good sowing way for barley especially in wet condition. However, parts of seeder have to be improved for barley sowing; 1) ridged width of partial tillage direct grain seeder should be $10{\sim}20cm$ wider than 10 cm, which is necessary for drainage during barley growing season in wet paddy field. 2) sowing width of partial tillage direct grain seeder was not same with one of drill seeder which was the best width for light interception and should be shorter than 30cm.

This study sought to disclose the problems surrounding the erroneous explanation of the title of the musical script 'Jeongdaeeop,' which is Jongmyojeryeak(Jongmyo Shrine ritual music), shown in Daeakhubo, Korea's treasure No.1291. Daehakhubo imitated and adopted expressions like 1 Byeon(change) and 1 Pyeon(edition), shown in the music written in the Annals of King Sejong, the foundation of Jongmyojeryeakbo music. Originally, 'Jeongdaeeop' recorded during the reign of King Sejong consisted of 6-Byeon and 13-Pyeon compositions, except Inlet and Outlet tunes. King Sejo, however, while rearranging this music into Jongmyo Shrine Mumuak music, reduced it to 9 tunes. And, when registering such arrangements in the musical scripts in the Annuals of King Sejo, he did not list the explanation of the titles as in the Annals of King Sejong. He just listed the nine tunes. In contrast to the musical scripts in the Annals of King Sejo, in Daeakhubo the details of Byeon and Pyeon under the nine tune titles are listed as in the Annals of King Sejong. This study revealed that Byeon and Pyeon expressed in Daeakhubo were the results of arbitrarily transcribing the different Byeon and Pyeon of 'Jeongdaeeop' and 'Balsang' in the Annals of King Sejong into the revised 'Jeongdaeeop' during the reign of King Sejo. Thus, under the titles of each score in 'Jeongdaeeop' of Daeakhubo are written the explanations of the muscial scores shown in both 'Jeongdaeeop' of the Annals of King Sejong and 'Balsang' of the Annals of King Sejong. Thus, the story of the son Ikjo is described even ahead of the story of the father Mokjo, and stories totally different from the original movements are described, creating overall errors. Such errors were presumably caused by powers that created the false musical script 'Sokakwonbo' during the Japanese colonial rule of Korea and disguised it as a traditional musical script.

This paper is written to results of excavated ChungJu ChangDong site located in ChungJu and the article Keumcheonchang in Joseonwangjosilrok. The structure rerics of compositing cornerstone-distance 420cm has been showing to Keumcheonchang of legend in region people. The solution to problems is that the enforcement of the river-shipping service linking Han River and NakDong River. King Taejong commanded the new tax-warehouse of 200 Kan to built at Keumcheon in ChungJu and named Keumcheonchang for the receipt of innner region and KyengSang Province. King Sejo established the foundation of the government owned tax-grain transportation systerm for the strong centralization by the sovereign right. This logistic system is gone the middle and the latter of Joseon Dynasty. Joseon Dynasty is absolutely dependent the national finance for government operation on the tax-grain from HaSamDo(ChungCheong JeonLa KyengSang) region. JoUn(tax-grain transportation by shipping) is the best logistic system in Korea surrounding sea. Joseon Dynasty has refomed the logistics base on GoRyeo's system that the Tax-grain transportation system by shipping. There is the tax-warehouses reducing from 13 numbers to 9 numbers and making up for the weak points in the matter of the Japanese Pirate and the ship wreck in transporting in the sea. The ship wreck in the sea specially make the matters of the reducing tax and political issues. We know that Keumcheonchang is operated ChuaSuCham(the government agency for taxgrain transportation by shipping at a warehouse) from King Taejong 11(1,411)year to King Sejo 11 (1,465)year. There is the result of enforcement the river-shipping service system for social stabilization and forward their new ideal in the first half Joseon Dynasty.

Geophysical well logging at various coal fields were carried out to study the characteristic response of domestic coal seams. Also a computer program is developed for quantitative analysis of coal logging data. Most coal seams penetrated by the drill holes, where the well logging were carried out, showed poor thickness and quality, and were severely altered. Therefore, majority of log data are inadequate for detailed quantitative analysis. The logs show, however, typical characteristics with related to coal seams, but interpretation should be made with caution because certain log response of demestic coals, mostly anthracite, are quite different to those of foreign coals, mostly bituminous. The developed comuter program has been proved as an effective one for identification of coal seams and lithology anslysis, and is expected to be succesfully used for coal quality analysis in cases of more diversified log data of good quality being obtained.

광자기 디스크의 자기 및 기록특성에 SiN 하지층이 미치는 영향에 대해서 연구하였다. PC기관에 4층구조막의 디스크를 DC 마그네트론 스퍼터링에 의해 성막하였으며 스퍼터링 압력이 증가함에 따라 SiN 박막의 표면이 거칠어 지고 주상형성장이 현저하게 나타났다. SiN 하지층의 비세조직의 변화는 자기기록막의 보자력, 수직이방성 등에는 영향을 미치지 않았지만 지구의 형 성과정은 SiN 하지층의 조직에 따라 민감하게 변화하였다. SiN 하지층이 Porous 할수록 광자기 디스크의 기록이 이루어 지는 임계파우워 값이 작고, 또한 자구의 형성이 이루어 지는 임계외자 계의 크기도 넓은 범위에서 나타났다. 광자기 디스크의 기록특성을 증대시키기 위해서는 자기기 록막의 성능과는 관계없이 치밀하고 표면이 평할한 SiN 하지층을 증착하는 것이 필수적임을 관 찰하였다.
