Yeasts isolated from wild flowers of Gyejoksan in Daejeon city, Oseosan in Chungchungnamdo, and Baekamsan in Jeollabukdo, Korea were identified by comparison of nucleotide sequences for PCR-amplified D1/D2 region of 26S rDNA or internal transcribed spacer (ITS) 1 and 2 including 5.8S rDNA using BLAST. Twelve yeast strains of ten species and seventeen yeast strains of ten species were isolated from wild flowers of Gyejoksan and Oseosan, respectively. And thirty seven yeast strains of twenty four species were isolated from wild flowers of Baekamsan. Total thirty four yeast species were isolated from three different sample collection areas, but only nine species were overlapped from the at least two different sampling areas: Cryptococcus sp., Cryptococcus aureus, Cryptococcus flavescens, Cryptococcus flavus, Metschnikowia sp., Pseudozyma aphidis, Rhodotorula glutinis, Sporobolomyces carnicolor, and Sporobolomyces ruberrimus. Among them only Cryptococcus aureus was occurred from all three different collection sites. Other twenty five species were restricted to specific collection site suggesting that each area has distinctive yeast flora.

With an increases in income levels and the establishment of a five-day workweek, the number of passengers using international passenger terminals around the world continues to grow every year. However, previous researches on port sector have focused on cargo, and neglected the study on the passenger attraction strategy of the international passenger terminal. Maximizing passenger attraction strategy of the international passenger terminal requires establishing and operating the port marketing strategy, which reflects port characteristics and the tourism marketing strategy, which reflects the hinterland characteristics in an integrated approach. Therefore, the study presents a marketing mix strategy for Daesan International Passenger Terminal based on existing literatures, and a tourism marketing strategy for Seosan city based on the "6A" factor. Recommendations for the Daesan Port include the grand image improvement strategy of Seosan city, utilization of marine tourism resources and development of various tourism products linked to the neighboring areas.

The ecology of rhizome rot incidence rates between Seosan, Chungnam and Bongdong, Chonbuk province were surveyed in this experiment. The rhizome rot incidence rate of Seosan was lower than that of Bongdong. The average ginger product of former province was 1,140kg, whereas it's 818kg per 10a. in latter province. Treatment after disease incidence frequently used fungicide at Seosan. There were different soil physiological property between fields. Although Eunhari and Yulsori were belong to Bongdong province, incidence rate was low at Eunhari, contained 23% clay and high incidence rate at Yulsori, approximately contained 60% silt. Many soil chemical properties of cultivated area were belong to optimum concentration range, but phosphate(P) was higher than optimum concentration, 450-550ppm. The number of soil fungi in the middle of cultivated season tended to show the highest. Both bacteria and actinomyces` number was similar to the result of fungi. The bacteria/fungi ratio was greatly different between surveyed fields.

Detrital zircons in iron-bearing quartzite of the Seosan Croup from southeastern part of the Cyeonggi Hassif were analysed for SHRIHP U-Pb ages. Among 42 analyses, 38 data yield concordant ages (less tan 10 % discordancy), and they concentrated at 1781~1898 Ma (n=19), $1781{\sim}1898\;Ma(n=19),\;1935{\sim}1941\;Ma(n=4),\;1996\;Ma,\;2120\;Ma\;2403{\sim}2459\;Ma(n=5)$, 2661 Ma and 3198 Ma. The data indicate that sedimentation of iron-bearing quartzite should be after ca 1.78 Ga (the youngest detrital zircon age), and argue against some of conventional idea that iron-bearing quartzite of the Seosan Group might be correlated with the Archean iron-bearing quartzite in the North China Craton.

지금까지의 수자원계획평가는 유역별 권역별로 이루어져 왔다. 다시 말해 지역적인 수자원계획평가는 제대로 이루어지지 않았다고 할 수 있다. 한 지역의 수자원계획평가를 하기 위해서는 그 지역의 물이용 순환시스템을 분석해야 하며, 이를 통해 유역의 기본 자료를 제공할 수 있을 뿐만 아니라 순환구조 및 현황 문제점 파악, 시스템 개선 등을 수행할 수 있다. 하지만 국내에서는 아직까지 종합적으로 물순환 및 물이용에 대해 제시된 연구결과는 거의 없으며, 각 순환요소에 대한 개별적인 연구가 수행된 경우가 있다. 도시용수의 순환시스템의 경우 전체적인 순환시스템에 대한 연구보다는 주거형태에 따른 회귀율의 산정과 같은 특정 분야에 대한 연구결과가 제시된 경우가 있으며, 농업용수에 대해서도 회귀율의 추정과 같은 연구가 제시되어 있는 정도로 관련 연구의 수행이 매우 미흡한 실정이다. 본 연구에서는 서산 지역의 물이용 순환시스템을 조사하여 분석함으로써 기 수립된 서산 지역의 장래 계획들의 타당성을 검증하고, 이에 대한 대책 및 문제점을 제시하고자 하며 장래에 일어날 수 있는 수량 및 수질 변화에 대한 상황들을 시나리오로 개발하여 분석함으로써 장래에 대한 수량, 수질을 연계한 수자원계획을 수립하고자 한다. 또한, 서산 지역의 대표적인 수원인 보령댐의 댐운영 및 가뭄 모니터링에 이용할 수 있도록 보령댐에 대한 가뭄지수(물공급능력지수, 표준물공급능력지수)를 분석하여 제시하고자 한다.

Exhumation mechanism of migmatite in orogenic belts provides insights into thermo-mechanical evolution of lithosphere in association with orogeny. This study deals with kinematics of structures in and around the Gwangcheon Gneiss, as a preliminary study on exhumation mechanism, which is a main constituent of a domal structure (viz., Oseosan Dome) in the Hongseong area, southwestern margin of the Gyeonggi massif. Geological structures in the Gwangcheon Gneiss, which mainly comprises southern and northwestern part of the Oseosan Dome, generally have kinematic component of top-outward shear. This feature is likely to represent diapiric dome-up movement. In addition, a high strain zone, by which the tectonic domain involving the Gwangcheon Gneiss is bounded on the west, show structural features with normal sense of shear component. Taking available (thermo)chronological data into account, it is interpreted that activation of the high strain zone and exhumation of the Gwangcheon Gneiss occurred during Late Triassic, when the Gyeonggi massif was widely affected by post-collisional processes. It means that the Gwangcheon Gneiss was diapirically moved up and exhumed in the footwall of extensional high strain zone in association with Triassic post-collisional processes.

To ensure that Korea continues to grow, past governments have been consistent in following a policy of advancing into Russia, Mongolia, and Eurasia. The northern economy can expect to achieve synergistic growth because its economic structure complements that of Korea, which has high energy demand and industrial development. There is also an opportunity to accelerate the growth of the China-Russia-Mongolia economic corridor, which is based on Russia's Look East Policy, China's One Belt One Road, and the Mongolian Steppe Road initiative. The Korean government is pursuing a New Northern Policy to achieve the goal of economic cooperation and peace building with other nations, including North Korea; this policy succeeds the Northern Policy pursued by the previous government. As international economic cooperation requires transportation infrastructure, the demand for shipping, which offers more advantages than road and rail transportation, will increase; thus, it is necessary to prepare for it. Korea's port cities, which have a port that serves as the nodal point for maritime transportation, need to prepare for the New Northern Policy. In this paper, the long-term development of Seosan-Daesan port in the was planned and the North Korea's opening-op plan was considered in accordance with the New Northern Policy. Because international cooperation between the government and the provincial cities is required, cooperation with the Port Authority is needed, along with the proactive attitude of Seosan City, Chungcheongnam-do. The Seosan-Daesan port, which is the center of the liquid energy cargo center, can become the base of the New Northern Policy Region; further, the port can be an opportunity to establish its position as a peaceful economic hub on the west coast of Korea.
