This Research will explore the meaning indicated in the landscape meaning and feature of literary group culture, focusing in Gurujeong(九老亭: pavilion for nine elders) and Samgaeseokmun(三溪石門: stone gate in three valleys) located in Dundeok-myun, Imshil-gun, and will seek to understand the implications by studying the cultural landscape spread out in the area. The place where Gurojeong and Samgaeseokmun is located is the meeting point of the three valleys, Dunnam stream, Osu stream, and Yul stream, which is the main location to view the beautiful scenery, which has the nickname as the dwelling place of a celestial being. Especially, based on the description of old maps, "Samgae(three valleys)" and "Samgaeseokmun" possesses significance as a landmark and shows a characteristic feature of landscape structures of low hills. Dangugurohwe(丹丘九老會: nine elders gathering on the dwelling of a celestial being) originated from Hyangsangurohwe(香山九老會: gathering of nine elders on a fragrant mountain), where Baekgeoi(白居易) of China was one of the main people. This group was organized by nine elders over the age of 60 desiring to view the scenery of Doyeonmyeong. The group enhanced the literary spirit on the low hill, erecting a tower, and enjoying the beautiful scenery changing every season with scholars from the same region. This phenomenon seems to have been formed upon the positive response to gatherings of elders, which were prevalent in the Joseon Dynasty. If the internal idea pursued by the group was "longevity," the external idea pursued can be summarized as "the spirit the respect for the elders." Naming the groups as 'Dangudae(place where the celestial being lives), Guseondong(valley of seeking a celestial life), Bangjangsan(mountain of a high priest), and Daecheondae(place of communicating with God) was likely a device to introspect oneself and symbolize one's life process. Furthermore, the reason Samgaeseokmun, which is an imitation of Choi, Chiwon's work, was built near Soyocheo, was probably to yearn the celestial land and based on the desire to follow Choi, Chiwon, who was the most self-fulfilling being presumed to have become a celestial being by practicing the pursuit of freedom, escaping from the reality. After tracing the symbolizing meaning of the four letters carved in the left side of the stone wall of Dangudae, the conclusion that this place was not only a place for literary gatherings of the nine elders of Saseong(four families), but was a place where the celestial being dwelled could be inferred. Corresponding with Dangudae and Gurojeong, which are places where the order of human and nature is harmonized and where its meaning associated with the location intensifies, arouses strong bond, can be said to be the symbol of the traces of celestial beings where the spirits of attachment to a certain place is embedded. The acts performed in Dangugurohwe were those of traditional leisure including strolling, viewing the scenery, drinking, composing poems, and playing instruments, and sometimes listening to stories, tea ceremony, prayers, and fishing were added, which indicates that the gathering had a strong tendency towards pastoral and hermit life.

To get the maximum diffusion boundary of thermal effluent of Youngkwang Nuclear Power Plant, paths of TGPS Buoy and temperatures of surface water are obtained to 4 times at spring tide during 1 year. According to the paths of TGPS Buoy, the flumes of thermal effluent are moved about 12km from outlet to SW or WSW direction. After 3∼4 times of tidal period the waters are reached to Chilsan Island because the ebb flow is more predominant than the flood flow in this area. At the spring and fall season, a sudden drop of surface water temperature is detected around 5km radius from the outlet. At the summer season, it is measured about 10km. On the other hand the flumes are continuously cooled down by the atmosphere condition at winter season.

The Japanese colonial authority investigated and institutionalized Korea's cultural properties for the purpose of governance. This process was conducted by Japanese officials and scholars, and systematized after making some changes. The Reservation Rule (1916) and the cultural properties designated in 1934 were actually the starting point for Korea's current cultural property policy. In the view of lineup of 'committee' that consider all of cultural property and changing of 'cultural property list', this study discusses the cultural property policy implemented by Joseon's Government-General, which can be summarized as follows. First, Joseon's Government-General formed a committee (Preservation Society) to formulate the cultural property policy, and had the policy implemented by appointing Governor officials who accounted for more than half the total number of officials of the institution. Although some Koreans were concerned about this, they had no influence on the matter. Second, the cultural properties listed by Joseon's Government-General are divided into three periods according to the lists. The compilation of the first list was led by Sekino Tadashi, who represented the grading system (1909~1916); while that of the second list (1917~1933) was led by Guroita Gatsumi, who represented listing (1917~1933). Guroita Gatsumi tried to erase Sekino Tadashi's list by formulating the cultural property policy and the list - a situation that was revealed in the system and the actual contents of the list. The third list was made as a list of designated cultural properties in 1934. This list also reflected the results of Sekino Tadashi investigation of the important cultural properties at existing temples that had been excluded from the previous regulations (1934~1945). In this way, a basic framework for the listing of Korean cultural properties was established in 1934.

Dispersion characteristics of surface discharge heat water in shallow region are investigated for coastal power plant with nearly constant depth of 20 meters by observing the seasonal depthwide temperature in several stations, which give or precise horizontal distribution and vertical structure of heat water. Surface discharged heat water in shallow coast in the Yellow Sea relies mainly on ambient tidal flow. so it behaves as free jet when the ambient now is strong and shows plumelike behavior during stagnant tide. According to observation the neat field region is estimated as 200-300 meters and shows distinct vertical profile and exponentially decreasing pattern from discharge point for this region. But there are no remarkable vertical distortion of temperature beyond 800 meters even though it is discharged from surface. Characteristic length scale model, CORMIX3, is applied and compared with the field date Overall tendency of CORMIX3 results resemble well with field data especially in near field and intermediate region.

일차생산은 화학합성 또는 광합성에 의하여 무기탄소가 유기물질로 전환되는 것을 의미한다. 수중의 일차생산자는 광합성을 통하여 유기물을 해당 수역에 공급하는 기능을 수행하며, 이는 수역의 상위 먹이 단계의 총생산력을 결정하는 주요 구성원이다. 한강은 하류로 갈수록 유속이 느리지만 수심이 깊어져 부착조류가 서식하기 쉽지 않은 환경이기에 대부분의 일차생산자는 식물플랑크톤이다. 과거 1994년 이후로 2017년까지 5년 간격으로 총 6회 연구된 결과, 해당 하천의 부영양화가 여름철에 발생하였다. 팔당댐 방류량과 지류의 유입에 의한 유기물 증가로 하천 내 1차 생산의 기여도가 증가하고 있으며, 이는 유기물 근원을 판정하여 수질오염에 대한 처리대책을 위해 지속적으로 연구가 필요하다. 따라서 본 연구는 한강본류에서 식물플랑크톤의 일차생산력을 조사하고, 유기물의 분해속도를 측정하여 당해 유역의 유기물 수지를 추정하여 한강 고유의 특성을 파악하여 부영양화에 의한 유기물 증가로 발생할 수 있는 수질오염을 예측하고자 한다. 조사유역은 한강의 팔당댐 방류구로부터 신곡수중보까지 전 구역 중 총 12개의 지점을 선정하였다. 기간은 2021년 5월부터 2022년 3월까지 계절별 2회로 총 8회 조사를 실시하였으며, 한강본류에서는 식물플랑크톤의 산소소비법을 통해 일차생산력과 유기물 분해속도를 조사하여 내부기원 유기물을 측정하였고, 한강본류로 유입되는 4개의 유입하천에서는 COD를 조사하여 외부기원 유기물을 측정하여 한강에서 발생하는 총유기물량을 산정하였다.

CCS (Carbon Capture and Storage) is a technical process to capture $CO_2$ from industrial and energy-based sources, to transfer and sequestrate impressed $CO_2$ in geological formations, oceans, or mineral carbonates. However, potential $CO_2$ leakage exists and causes environmental problems. Thus, this study was conducted to analyze the spatial and temporal variations of $CO_2$ fluxes and concentrations after artificial $CO_2$ release. The Environmental Impact Evaluation Test Facility (EIT) was built in Eumseong, Korea in 2015. Approximately 34kg $CO_2$ /day/zone were injected at Zones 2, 3, and 4 among the total of 5 zones from October 26 to 30, 2015. $CO_2$ fluxes were measured every 30 minutes at the surface at 0m, 1.5m, 2.5m, and 10m from the $CO_2$ releasing well using LI-8100A until November 13, 2015, and $CO_2$ concentrations were measured once a day at 15cm, 30cm, and 60cm depths at every 0m, 1.5m, 2.5m, 5m, and 10m from the well using GA5000 until November 28, 2015. $CO_2$ flux at 0m from the well started increasing on the fifth day after $CO_2$ release started, and continued to increase until November 13 even though the artificial $CO_2$ release stopped. $CO_2$ fluxes measured at 2.5m, 5.0m, and 10m from the well were not significantly different with each other. On the other hand, soil $CO_2$ concentration was shown as 38.4% at 60cm depth at 0m from the well in Zone 3 on the next day after $CO_2$ release started. Soil $CO_2$ was horizontally spreaded overtime, and detected up to 5m away from the well in all zones until $CO_2$ release stopped. Also, soil $CO_2$ concentrations at 30cm and 60cm depths at 0m from the well were measured similarly as $50.6{\pm}25.4%$ and $55.3{\pm}25.6%$, respectively, followed by 30cm depth ($31.3{\pm}17.2%$) which was significantly lower than those measured at the other depths on the final day of $CO_2$ release period. Soil $CO_2$ concentrations at all depths in all zones were gradually decreased for about 1 month after $CO_2$ release stopped, but still higher than those of the first day after $CO_2$ release stared. In conclusion, the closer the distance from the well and the deeper the depth, the higher $CO_2$ fluxes and concentrations occurred. Also, long-term monitoring should be required because the leaked $CO_2$ gas can remains in the soil for a long time even if the leakage stopped.

The main purpose of this study is to explore the structure of local government social welfare finance and tendency of changing structure and what affects the change. We select GuRoGu budget from 2000 to 2007 as one of local governments in Korea to perform the study goal. After we analyzed the contents of the budget, we have developed the framework of analysis for reclassifying local government welfare budget. First of all, we find utility of the framework of analysis which classify local government social welfare budget as target groups, properties, and the source of the finance. Secondly, the structure of local government welfare finance has changed for 8 years. The rate of finance for direct service has risen more than that for indirect service, and the rate of finance providing material(or service) type has risen more than that of providing monetary type. The rate of the finance from central government has grown up rapidly, whereas that from local government has fallen off. The hypotheses that the rate of financial self-reliance and the increase rate of social welfare expenditure to the previous year play a significant role to the rate of social welfare expenditure are not clear in our study. But we find the central government's effects to the local government welfare budget has grown up. So, we propose if we analyze the hypothesis of incrementalism, we must divide the effects of the previous year expenditure from the effects of central government's policy.
