  • 실험지역으로 선정된 거제도와 남해도에 대해 Yamada(1999)의 산치차수구분을 시도해 보았으며, 그 결과를 바탕으로 산지차수구분을 남한 전 지역에 확대·적용하였다. 남한 지역의 최고 산지차수는 5차수였는데, 설악·태백산지, 지리·덕유산지, 영남알프스산지 모두 3곳으로 확인되었다. 4차수 산지는 10곳, 3차수 산지는 87곳에 나타난다. 5차수 산지는 대략 한반도의 융기축과 관련이 있는 것으로 판단되며, 4차수와 3차수 산지의 분포는 2차산맥과 같은 북동-남서의 방향성을 지니고 있다. 한편 하천차수법칙과 마찬가지로 차수별 산지 개수, 면적, 비고의 로그함수 값이 차수에 대해 선형관계를 이루고 있다. 차수별로 구분된 산지 중에서 기존의 산맥체계에서 고려하지 않은 산체들을 확인할 수 있었는데, 이들은 한반도의 지체구조를 보다 자세하게 이해하는 근거로 활용될 수 있다. 국립공원 및 도립공원은 대부분 5, 4, 3차수 산지에 분포하고 있다. 특히 속리산국립공원이 남한 지역의 대표적인 두 산체인 지리·덕유산지와 설악·태백산지를 연결하는 생태축의 중요한 연결고리 역할을 하고 있음을 확인할 수 있었다. 이는 산치차수구분법이 지니고 있는 지형학적 의미뿐만 아니라 실용적 가치를 시사해준다.

  • 한반도의 약 70% 이상을 차지하고 있는 산지는 많은 산들과 산맥으로 이루어져 있으며, 산맥들은 대기환경에 큰 영향을 준다. 산맥의 분류조사는 1900-1902년 일본학자에 의거 수행 된 후, 현재 산맥의 이름이 매우 많고 혼선이 되고 있다. 본 연구는 기존의 산맥 이름과 그 분류를 간단히 하여 사회적 교육적 활용에 가치를 두고 있다. 먼저, 중국의 만주로부터 (대)한반도까지 주축을 이루는 세계적인 제2차 중규모산맥을 단일 이름인 고려산맥으로 명명하였다. 그리고, 고려산맥에 수반되는 지역적인 제3차 산맥들은 지린(길림)산맥, 함경산맥, 태백산맥, 소백산맥으로 분류하고, 그 다음 제4차 산맥은 랴오닝산맥, 옌볜(연변)산맥, 함북산맥, 평북산맥, 황해산맥, 차령산맥, 경상산맥, 남해산맥 등 8개의 중소 산맥으로 분류 하였다. 일반적으로 한반도의 산맥들은 지구규모 대순환의 영향을 지속적으로 받고 있다. 산맥의 풍상과 풍하 측에서 발생하는 공기환경적인 변화에 따라, 인간과 생태계에 주는 대기환경의 영향평가와 그 감시의 필요성을 강조하였다.

  • This study was conducted to perform various sensitivity experiments using WRF (Weather Research and Forecasting) model in order to determine the effects of terrains of the Korean Peninsula and the land-sea thermal contrast on the formation and development of the convergent cloud band for the cases of 1 February 2012. The sensitivity experiments consist of the following five ones: CNTL experiment (control experiment), and TMBT experiment, BDMT experiment and ALL experiment that set the terrain altitude of Taeback Mountains and Northern mountain complex as zero, respectively, and the altitude of the above-mentioned two mountains as zero, and LANDSEA experiment that set to change the Korean Peninsula into sea in order to find out the land-sea thermal contrast effect. These experiment results showed that a cold air current stemming from the Siberian high pressure met the group of northern mountains with high topography altitude and was separated into two air currents. These two separated air currents met each other again on the Middle and Northern East Sea, downstream of the group of northern mountains and converged finally, creating the convergent cloud band. And these experiments suggested that the convergent cloud band located on the Middle and Northern East Sea, and the cloud band lying on the southern East sea to the coastal waters of the Japanese Island facing the East Sea, were generated and developed by different dynamical mechanisms. Also it was found that the topography of Taeback Mountains created a warm air advection region due to temperature rise by adiabatic compression near the coastal waters of Yeongdong Region, downstream of the mountains. In conclusion, these experiment results clearly showed that the most essential factor having an effect on the generation and development of the convergent cloud band was the topography effect of the northern mountain complex, and that the land-sea thermal contrast effect was insignificant.

  • We report the first identification of a spawning ground of the blackfin flounder Glyptocephlaus stelleri near the Wangdol-cho sea mountains, located in the southern East Sea. Eggs and larval fish of G. stelleri were collected during April and June, 2014, when an abundance of eggs was found in the southern area of Wangdol-cho. Our findings suggest that G. stelleri prefers to spawn in the vicinity of the off-shore sea mountains, where the temperature is between 10 and $12^{\circ}C$ and the water depth is 100 m, rather than inshore.

  • This study intends to investigate the measuring scales, locations and scales through arrangement plans for a research on construction plans. Through an analysis of the artifacts-measuring scales, the relation of two scales found, which further helped suppose the measuring scales applied during the foundation period. Southern dynasties-scale was still used even after the capital was transferred to Sabi till Tang-scale was introduced. Tang-scale was used for Buddhist temples mostly founded in the 7th century. On the other hand, Goguryo-scale seemed to be used almost at the same period as Southern dynasties-scale used, but it seemed that Goguryo-scale disappeared earlier than Southern dynasties-scale. The locations of Buddhist temples could be classified into mountains, flatlands and mountain valley. Buddhist temples founded in mountains were mostly small-sized, but ones located on flatlands could secure flat fields through mounding operations. In addition, through location conditions of Neungsa and Wangheungsa, it was possible to find out the district setting of Sabi Capital Castle. Finally, the expansion range of Buddhist temples were found to be towards the east and the west. As for the scales of temples according to such conditions of location, it was found a similarity in Temple sites. In general, it was possible to assume that the scales of Buddhist temples tended to be expanded along with spatial expansion and there were regular systems in Buddhist temples related to the Royal family. Through the analysis of arrangement plans between individual buildings, it was found that the basic arrangement of Gate-Pagoda-Main Hall-Lecture Hall was preserved, but the proportion of distances between individual buildings varied depending on cases. As a result, there were differences between scales of entire building sites, construction subjective influences and master plan for each location of a Buddhist temple.

  • This study was made on the taxa Chrysanthemum zawadskii complex that grow in South Korea on the basis of chromosomes, epidermis, pollens and gross morphology. I have found four types of chromosome numbers, 36, 45, 54, and 72 as a polyploidal series. Even though the gross morphology was quite similar almost the same gross morphology, chromosome number was different among the taxa. The taxa of 36 chromosomes present broad and fine lobed leaves which grow separately, broad leafed taxon in the mainland of Korea and the other's in Ullungdo Island which is isolated form the mainland in the East Sea. The taxa of 54 chromosomes are also present in the broad and in the fine lobed leaves. The fine lobed leave taxon grows in central to northern Korea and in the high altitude of mountains. Broad leafed taxon grows in central to southern Korea and comparatively lower altitude of the mountains. The taxon of 72 chromosomes is grown in the high altitude of Mt. Hallasan which is isolated from the mainland of Korea. According to this study of Chrysanthemum zawadskii complex, I have arranged the scientific names, as Chrysanthemum zawadskii subsp. latilobum, subsp. acutilobum, subsp. naktongenese, subsp. lucidum, subsp. coreanum and hybrid between subsp. acutilobum X subsp. latilobum.

  • Objective: Data from a recent genome-wide association studiesy of gastric cancer (GC) and oesophageal squamous cell carcinoma in Chinese living in the Taihang Mountains of north-central China suggest that 1q22 and 10q23 are susceptibility-associated regions for GC. However, this has not been confirmed in southern Chinese populations. The aim of this study was to investigate whether these polymorphisms at 1q22 and 10q23 are associated with the risk of GC in a southern Chinese population. Methods: We selected seven top significant associated single nucleotide polymorphisms (SNPs) at 1q22 and 10q23 and conducted a population-based case-control study in a southern Chinese population. Genotypes were determined using MassARRAYTM system (Sequenome, San Diego, CA). Results: Two SNPs at 1q22, rs4072037 and rs4460629, were significantly associated with a reduced risk of GC, best fitting the dominant genetic model. Logistic regression models adjusted for age and sex showed that rs4072037 AG and GG (OR=0.64, P=0.017, compared with AA) and rs4460629 CT and TT (OR=0.54, P=0.0016, compared with TT) significantly reduced the risk of GC. However, no significant results for the five SNPs at 10q23 were obtained in this study. Conclusion: These outcomes indicate that 1q22 is associated with GC susceptibility in this southern Chinese population, while an association for the locus at 10q23 was not confirmed.
