In this paper, I chose one of various agenda for life in a philosophical film world view and explored the core of dialectical relation between free will and responsibility. Freedom and responsibility, Existential and inferiority, etc, The conflict of humanity on the crisis of faith have been A comparative study based on the discussions of East Asian religious philosophy and Western philosophy. Including compare the three commonalities and differences with Jean Paul Sartre's 'subjectivity ideology due to the existence of free will' on existentialism in contemporary Western philosophy and The theory of the 'moral autonomy originating in the good will' of the Enlightenment philosopher Immanuel Kant and Concept of 'consciousness' of the life essence of Keiji Nishitani Based on the analysis of the film. In addition, the problem of free will in the viewpoint of nature, along with the individual's point of view, is comprehensively supplemented by the idea of the "nothingness" of the philosopher Zhuang Zhou. A selection of the Polish film Dekalog: Eight and make a basic conclusion of the final by argumentation and analysis as a case of the dialectical relation between the free will and responsibility.

The Nakdong Delta can be identified by two different geomorphic units. The first one is the upper delta. This is mostly composed of inter-distributary islands that are largely influenced by fluvial processes and attributed to the development of these islands along the river. The other one is the lower delta which is mostly composed of beach ridges. Barrier islands are largely effected by wave processes promoted by the development almost at a right angle to the river. Influenced by the longshore current which flows to the same direction, barrier islands located in the Nakdong river estuary are developing from east to west direction. As a result, the eastern end of the barrier islands are growing toward the north-west direction effected by tidal current which moves toward the same direction. Barrier islands include the Sinho Island, the Jinwoo Island, the Daema deung, the Janga Island, the Baghap deung, the Sae deung, and the Chulsae deung(Doyeo deung). They have orderly emerged from the sea since 1861. Since 2008, a new Deung, a sand dune growing under sea, has been developing rapidly from Chulsae deung to the Dadaepo beach. It made the sailing of small fisher boats impossible. Tidal currents transported a lot of sand and silt around the barrier islands. The landscape of Nakdong river estuary where many barrier islands are distributed will change rapidly affecting land environment.

건설된 도로를 효율적으로 이용하고, 통행자의 편리성을 향상시키기 위해 첨단 여행자 정보체계(ATIS)를 활용할 수 있다. ATIS 체계하에서 노선정보를 통행자에게 제공하기 위해서는 교차로에서의 회전으로 인한 지체를 정확하게 반영할 수 있는 효율적인 최단경로 알고리즘이 필요하다. 하지만 기존의 최단경로탐색 알고리즘은 좌회전 금지, U-turn, P-turn 등 교차로에서의 회전으로 인한 지체를 정확히 반영 못한다는 단점을 갖고 있다. 그러므로 본 논문에서는 이러한 단점을 극복하기 위해 수정형 덩굴망 알고리즘을 재발하였다. 수정형 덩굴망 알고리즘은 노드표지(node labelling) 방법에 있어서는 기존의 덩굴망 알고리즘의 노드표지 방법과 개념적으로 동일하여 이용상의 편리성을 갖도록 하였으며, 최단경로 탐색기능에 있어서는 링크탐색알고리즘(혹은 링크표지기법)이 갖고 있는 장잠을 다 반영할 수 있는 기법으로 개발하였다. 수정형 덩굴망 알고리즘은 노드표지에 있어 특정 노드로 유입하는 방향에 따라 노드표지를 별도로 기록하였다. 따라서 교차로에서의 좌회전, 우회전 및 직진은 물론 U-turn의 경우에도 추가적인 절차 없이 현실적인 최단 경로를 탐색할 수 있도록 하였다. 또한 본 논문은 최단경로의 역추적 방법을 개선하여 좌회전 금지, U-turn, P-turn 및 기타 회전에 의한 지체등을 각 교차로마다 정확히 반영함으로써 비합리적인 최단경로가 추적되는 것을 근본적으로 차단하도록 하였다. 따라서 본 연구에서 개발한 수정형 덩굴망 최단경로탐색 알고리즘은 교차로에서의 회전지체 및 회전금지를 현실적으로 잘 반영함으로써 정확한 노선정보를 요구하는 ATIS체계를 분석하는데 유용하게 활용될 수 있는 기법이다.장자료를 통해 구하기란 현실적으로 불가능하므로, 본 연구에서는 이러한 제약점을 극복할 수 있는 근사적인 지체시간을 계산하는 방법을 제시한 점에서 의미를 갖을 수 있다.수들은 직업의 선택이나 소득을 예측하기 위한 요소들로 포함될 수 없었다. 따라서 후속연구에서는 이를 보완해야 할 것이며, 최근 들어 우리 나라에서도 재택근무에 대한 관심이 대두되고 있으나 아직 개념정의나 그 중요성과 가치, 그리고 실태 파악과 같은 연구가 활발히 이루어지지 못하고 있으므로 이에 대한 심층적인 연구가 행해져야 할 것이다.d similar flower proceeding dates in all branches. but "Daepung" showed similar flower proceeding dates in all branches.est in HB.

In order to investigate frequency of fungal contamination in ginseng sprout, we collected 18 types of retail ginseng sprouts and analyzed them. Overall frequency of fungal contamination ranged from 113.3 to 174.1% with the highest occurrence of Penicillium spp. Fungal detection rate was significantly higher in moss than in stem, leaf and root of ginseng sprout. Penicillium spp. occurred in leaf and stem with the highest incidence and Fusarium spp., in root. Among Penicillium spp. and Fusarium spp., P. olsonii and F. oxysporum were dominant, respectively. Nine Fusarium species, Aspergillus westerdijkiae, Aspergillus flavus, and 11 Penicillium species were identified by phylogenetic analysis. PCR screening of mycotoxigenic potential revealed that 19 out of 25 isolates tested were positive for respective mycotoxin biosynthetic gene. Two 2 A. flavus and 11 A. westerdijkiae isolates produced varying amount of aflatoxin or ochratoxin A in czapek yeast extract brothsome of which showed high levels of mycotoxin production. These results suggests a need for continuous monitoring and management program to control fungal contamination in the ginseng sprout production chain.

We analyzed rice sample with scab (collected in 2017) for fungal occurrence and found that frequency of Fusarium spp. was the highest among fungal genera. Within Fusarium, Fusarium asiaticum-nivalenol type dominated as 79%. Among mycotoxins, zearalenone was the highest toxin detected (1117 ng/g), followed by deoxynivalenol (163 ng/g), 15-acetyl deoxynivalenol (155 ng/g), nivalenol (110 ng/g). Analysis of mycotoxin levels in scabby and healthy grains (collected in 2015) revealed that both grain samples were contaminated with zearalenone. However, level difference of zearalenone between the samples was over 5 times as the scabby samples were 1400-2370 ng/g, while healthy ones were 240-430 ng/g. This result indicates that scabby grains should be removed when harvest to reduce zearalenone contamination in rice.

Fusarium infection rate of the paddy rice grain after harvest seemed to be influenced by the average temperature from late July (before heading) to the end of September (during ripening). In case of 2010 and 2013 in which average temperature of the same period was similar, Fusarium infection was related to cumulative precipitation, cumulative precipitation days, and precipitation durations over two days. The distribution ratio of Fusarium species complex isolated from paddy rice grains after harvest was 57% in 2010 and 45% in 2013 for Fusarium graminearum species complex (FGSC), 35% and 50% for Fusarium incarnatum-equiseti species complex, and 8% and 5% for Fusarium fujikuroi species complex (FFSC). The distribution ratios of FGSC and FFSC were higher in 2010 than 2013. Among the total 26 promoted rice varieties, the 'Mihyang' showed resistant response against the natural infection with Fusarium species belonging to FGSC and the varieties of 'Nampyeong', 'Hi-ami'and 'Younghojinmi' showed resistant response against the natural infection with overall Fusarium pathogens. Majority of the promoted rice varieties could not be classified for resistance or susceptibility. These results are valuable as basic data to determine the resistance and susceptibility of rice variety against Fusarium spp. infection in the field.

Many earrings were excavated from Bujang-ri site in Seosan with various prestige goods such as the golden crowns, shoes and decorated swords. This proved that Bujang-ri site in Seosan fell within Hanseong Backjae area of influence in the 4~5th centuries. The earpieces of excavated prestige goods had been considred subordinate elements compared with the golden crowns, shoes and decorated swords. Twenty one earpieces were excavated from Bujang-ri site and formative features and material characteristics of them were analyzed by microscope and XRF. The material and manufacturing technique of earpieces were compared with excavated aspects of prestige goods. As a results, the earpieces that made of a small amount gold and by simple technique were the most whereas the earpieces that required advanced skills such as welding, workmanship and high purity of gold were smaller. Also the earpieces that required advanced skills were excavated from the tombs where the prestige goods such as the golden crowns, shoes and decorated swords appeared. Therefore, considering Hanseong Backjae used the gold wares as means in showing power for local influence men, the earpiece from Bujang-ri site in Seosan would be the standard on superiority of tomb's owner as gold purity.

The paleogenetic analysis has become an increasingly important subject of archaeological, anthropological, biological as well as public interest. Recently, scientific research for human skeletal remains was more activated because of increasing awareness of the valuable archaeological information by the ancient DNA analysis. State of preservation of organic remains vary in different soil and burying environmental condition. Almost all available tissue disappear to analysis ancient DNA of bone in acidic soil caused by climate and geological features in Korea. Many preserved human remains excavated in the 'Heogwakmyo'(limelayered tomb of Chosun Dynasty Period) is able to explain through the relationship between burial conditions and bone survival form the burial method and ceremony. Ancient DNA analysis of excavated human bone form ancient tomb requires to remove contaminants such as microorganism's DNA and soil components that affect authentic results. Particularly, contamination control of contemporary human DNA is major serious problem and should verified by criteria of authenticity. In order to understand migration and culture of ancient population, when possible, ancient DNA studies needs to go abreast both radiocarbon and stable isotope studies because the dietary inferences will suggest ancient subsistence and settlement patterns. Also when the paleogenetic research supported with the arts and humanities research such as physical anthropology and archaeology, more valuable ancient genetic information is providing a unique results about evolutionary and population genetics studies to reconstruct the past.

Among Natural monument birds, a total of 11 species and 2,209 individuals were found in Nakdong river estuary from March 2007 to February 2008 including Eurasian Oystereacher (Haematopus ostralegus; No. 326), Mandarin Duck (Aix galericulata; No.327), Tundra Swan (Cygnus columbianus; No.201-1), Whooper Swan (Cygnus cygnus; No.201-2), Black-faced Spoonbilll (Platalea minor; No.205-1), Eurasian Spoonbill (Platalea leucorodia ; No.205-2), Steller's Sea Eagle (Haliaeetus pelagicus; No.243-3), White-tailed Sea Eagle (Haliaeetus albicilla ; No.243-4), Hen Harrier (Circus cyaneus; No.323-6), Common Kestrel (Falco tinnunculus; No.323-8) and Swan Goose (Anser cygnoides; No.325-1). Among the habitats for migratory birds in Korea, the Nakdong river estuary is the only place where more than 2,000 individuals of Whooper Swan(Cygnus cygnus) spend winter. Eulsukdo, Myeongji Flat and neighboring tidal flats (Myeonggeummeori, Baikhapdeung, Doyodeung, Jangjado, etc.) are major habitats for natural monument birds such as Eurasian Spoonbill(Platalea leucorodia ), Whooper Swan(Cygnus cygnus) and Swan Goose(Anser cygnoides). A colony of aquatic plants such as Common Bulrush(Scirpus triqueter) and Common Reed(Phragmites communis) serves as a feeding and resting place for birds in the Anatidae family including ducks, swans and geese. Plans for management and conservation of the habitats and the natural monument birds in Nakdong river estuary are as follows: minimization of water contamination, construction and management of aquatic plants habitats, protection of sandbanks, security of stable habitats, and consistent monitoring.
