Background: Woori-Heukdon (KWH) is a Korean synthetic pig breed generated using Chookjin-Duroc (KCD), Chookjin-Chamdon (KCC), and their crossbreds. Currently, there is a severe lack of studies investigating the Korean breed populations including wild boars (KWB) throughout the genome. Objective: This study was performed to investigate the genetic characteristics of Korean pig populations at the genome-wide level. Methods: Using the SNP dataset derived from genotyped and downloaded datasets using the Illumina PorcineSNP60K BeadChip, we compared the genomes of 532 individuals derived from 23 pig breeds to assess the genetic diversity, inbreeding coefficient, genetic differentiation, and population structure. Results: KWB showed the lowest average expected heterozygosity (HE = 0.1904), while KWH showed the highest genetic diversity (HE = 0.02859) among Korean populations. We verified that the genetic composition of KWH, showing USD of 74.8% and KCC of 25.2% in ADMIXTURE analysis. In population structure analyses, KCC was consistently shown to be separated from other pig populations. In addition, we observed gene flow from Western pigs to a part of Chinese populations. Conclusion: This study showed that Korean native pigs, KCC have genetic differences in comparison with Chinese and Western pigs; despite some historical records and recent genetic studies, we could not find any clear evidence that KCC was significantly influenced by Chinese or Western breeds in this study. We also verified the theoretical genomic composition of KWH at the molecular level in structure analyses. To our knowledge, this is the first genomic study to investigate the genomic characteristics of KWH and KCC.

Whenever there have been reforms of the high school curricula, the contents and formation of physics education have also been changed much. Especially the Energy parts has influenced not only various fields of studies but also our daily lives. Recently the influence is increasingly striking Therefore, how to instruct physics, especially Energy parts, at high school level should be carefully considered Thus, the changes in Energy parts at high school level dut to the several stages of the curricular reforms since 1945 should be analyzed. Particular emphasis should be given in change of the level and method of physics instruction as well as physics experiments contained in the text books.

This study uses a cointegration method based on point-location model to analyze spatial price relationship among kyungpook cattle markets in korea. According to the results, there is a cointegration relationship between prices of male and female cattle markets. This suggest that these markets are linked with the single market spatially. The prices of Koryoung female cattle market in south and Youngju female cattle market in north have influence on the price change of other female cattle market and play an important role in price movement of other female cattles. In case of impulse response results, the price of female cattle market appears to adjust to equilibrium level faster than that of male cattle market.

Saemaul Undong started in 1970 to be driven to arrange the small cities for the purpose of improving the rural surrounding. Then Saemaul Undong was spreaded over every work place including the rurals and cities over the country of Korea through an experimental stages. The main purposes of Saemaul Undong are the development of spirit, the improvement of environment and the increase of income, and war driven on the basis of the principle of general development. The spirit is a movement to render service to the national development by accomplishing the development of spirit and the economical development with a trnity of village people, village leader, and government together on the basis of self-support, self-reliance and cooperation. Therefore, Saemaul Undong is a pan-national movement of effort for the modernization of fatherland by promoting self-development in order that the village people as well as nationals may better theirselves' life. Now Semaul Undong needs the voluntary participation of people at the time when the local self-government will be realized in the near future. In this paper, Saemaul Undong and the policy in order to take effect on the importance of land shall be realized under the positive participation of people of Saemaul Undong and policy of land. The content of the statement of this theory has a case that the people residing in Mokdong of citizen participated in the development of Mokdong area.

Today the importance of the function of cadastre has deen newly recognized by the government, the society, the individual, and organization. The land planning by the government, The use of land for industries, and the individual's ownership and its administration hold much more weight in our economic actuality. Furthermore, as the land is the marginal land and is required for taking measures to the demesne of the increase of population and for rendering great services to the national welfare coming from the upraising level of income and the change of the view of value. The more the land is important, the more registry is needed, for the actuality of the land is accompanied with the theory of cadastre. The use of land ley human being who has developed the surface of the land has been to the solid times, and has been also diversified into the development of sea. But the cadastre system has not accepted it yet and has not given full answers to diverse demand because of poverty of theory. Today the advanced nations have much interests in the general cadastre system and the studies related to the cadastre on the ground of the importance of the cadastre. In the meantime, mainly, the practical theory and the surveying technique developed by the working- level staffs have been arrived at a regular level, but the theory of cadastre as an information sources to act up to the desire of the modern still. The systematization of the theory of cadastre is a problem of the modern cadastre, and this shall be a driving power to bloom the flower of the land culture in this land. Therefore, this treatise is written on the focus of interests in the systematization of the theory.

인천 연안역의 수온 및 염분의 계절 변화

국립수산진흥원의 한국 연안 어장환경 오염조사 결과 보고서를 사용하여, 인천 연안역의 수온 및 염분의 계절변화의 특성을 살펴 보았다. 수온의 연변화는 인천항과 소래에 이르는 조간대 해역이 만의 바깥쪽 해역보다도 수온의 연평균이 높고, 진폭도 크며, 위상도 빨랐다. 염분의 연변화는 인천항과 소래에 이르는 조간대 해역이만의 바깥쪽 해역보다도 연평균은 낮고, 진폭은 크며, 위상은 느리게 나타났다. 이러한 특성은 T-S도를 이용하여 나타낸 수괴의 계절 변화에서도 뚜렷하게 볼 수 있었다. 즉, 인천 연안역의 수괴는 수온과 염분의 연교차가 큰 인천과 소래에 이르는 조간대 해역과 염분 변동에 영향을 주는 강수나 증발, 담수 유입의 계절적 변화에 비교적 영향을 적게 받는 만의 바깥쪽 해역으로 구분할 수 있었다. 또한 얕은 수심과 강한 조류로 인하여 수층이 연중 거의 혼합된 분포를 보이고 있었다. The seasonal data obtained at National Fisheries Research and Development Institute from 1989 to 1994 were analyzed to investigate the seasonal variations of temperature and salinity in Incheon coastal area. In the tidal flats covering from Incheon harbor to Sorae, the mean temperatures are higher, the amplitudes of temperatures are larger, and the phases of temperatures are faster than those of outer tidal flats. In the tidal flats, the mean salinities are lower, its amplitudes are larger, and its phases are later than those of outer tidal flats. These suggest that Incheon coastal area may be divided into two areas: the tidal flats from Incheon harbor to Sorae, which is largely influenced by the seasonal variation of solar heating, precipitation and evaporation and the outer tidal flats, which is slightly influenced by the effects of seasonal variation of salinity.

Based on the observation on 20, 23 and 26 July 2004, the distributions of temperature, salinity and stratification was investigated in relation to ebb, turn of tide and flood. The results are as follows: 1) The high temperature and low saline water with 23.5-24.0℃ and 32.4~33.0psu existed at Naro Island. 2) The cold surface water below 21.00 and 33.0~33.4psu appeared in the area near Gae Island and Geumo Island. 3) The cold and saline water, below 24.0℃ at the surface and 17.0℃ near the bottom, 32.8~33.8psu at the surface and 33.8~34.0psu near the bottom, existed in Sori Island. These waters were more saline compared to the South Sea Coastal Water with about 31.8psu. This suggests that the oceanic saline water intruded into the Bottol Bada through the area near Sori Island. The stratification appeared during all the observation periods due to a high solar radiation of 22MJ/m², and a weak wind speed of 2.9m/s on the average while the mean speed of wind in July is around 3.9 m/s. It qualitatively suggested that the stratification was maintained during the observation periods because of a high solar radiation, a weak wind speed and intrusion of saline oceanic water.
