        閔丙燮 忠南大學校 1959 論文集 Vol.1 No.-

        There are 683 Irrigation Associations in Korea as of Dec. 1958, and those Irrigation Associations have 1,266 reservoirs in which 202 projects are now under way. Through the investigation about those irrigation reservoirs, following conclusions were found: ⑴ Dams of irrigation reservoirs are all earth dam except only 3 and those earth dams type is almost central puddle core type and a few of them are homogeneous type but no one Zone type. The height of the highest dam is 26.1m high and a half of them are below than 10m and dams which are lower than 15m. are 80percent. ⑵ Average Benefited area by one reservoir is largely narrower than 300 chung bo(1 chung bo=2.45 acre) and they are occupying 90 percent in number and the largest one is 7,319 chung bo and it’s storage capacity is 4,608 chung-meter. ⑶ Ratio of catchment area to benefited area is 3.86 in its total average, and the ratio 5∼10 in mountainous district such as Jaeju-Do, Kangwon Do, Kyung sang Buk-Do, on the otherhand the ratio is about 3 in the plain district such as Kyung-Gi-Do, Chunlla Buk-Do, Chung Chung Nam-Do, Chunlla Nam-Do. ⑷ It is the representative method of side-slope protection that In-side slope is faced by stone and out side slope by lawn works. The conclusions of in side slope & Out-side slope are shown in Tab. 13′, 14′, that is in side slope is 0.3:1 or 0.5:1 larger than out-side slope. ⑸ Conclusions of dam crest & freeboard are shown in Tab. 15′, 16′ and the higher the height of dam. the larger dam crest & freeboard are forming. ⑹ The average storage capacity per unit area is 42cm deep, so this means rservoirs necessitate 42cm deep water to supply for the paddy field through the irrigation period and 42cm deep water must be stored in reservoir in Korea. ⑺ Most of spillways are chute type, free overflow type & side-weir type, while there are a few of sluice gate type, and there is only one siphon spillway as the special type, but no one such as shaft spillway, and 76 percent of them in number was set down at the continuation of dam, and overflow head on the spillway is largely lower than 1.2m. ⑻ Most of spill-way’s section was designed by taking the maximum daily rainfall of 200∼350mm. ⑼ A great number of water-intaking apparatus are inclined conduit and conduit and out-let tower are constructed in the reservoirs which are deeper than 9m and most of outlet tunnels are passed under dam except a few projects. ⑽ The reservoirs which are losing water are 6 percent in number but their discharge is very little and one of the main reasons of loss is that the central puddle core was setting roughly and badly, and the other one is that the rock of foundation forming cracks.

        cDNA Cloning of Korean Human Norovirus and Nucleotidylylation of VPg by Norovirus RNA-Dependent RNA Polymerase

        민병섭,한강록,이정인,양재명 한국미생물학회 2012 The journal of microbiology Vol.50 No.4

        Norovirus, a member of the Caliciviridae family, is a major causative agent of gastroenteritis worldwide. The cDNA of the entire genome of human norovirus (HuNV) was cloned using the RNA extracted from the stool sample of a Korean patient. The RNA genome consists of 7,559 nucleotides,carries 3 open reading frames (ORFs), 5' and 3' noncoding regions, and a poly(A) tail at the 3'end. Phylogenic analysis of the nucleotide sequence indicated that it belongs to GII.4,the most dominant genogroup. To analyze RNA synthesis and nucleotidylylation of VPg by RNA-dependent RNA polymerase (RdRp), recombinant RdRp and VPg were expressed in Escherichia coli as His-tagged forms. The HuNV RdRp exhibited template and divalent cation-dependent RNA synthesis in vitro. The HuNV RdRp nucleotidylylated HuNV VPg but not murine norovirus (MNV) VPg, whereas MNV RdRp nucleotidylylated both MNV and HuNV VPg more efficiently than HuNV RdRp.

        An appended map is regarded as complementary to an history textbook and along with the textbook, it helps to achieve the vital goals of history education indicated in the curriculum. In recent years, history textbooks have increasingly had various informative materials. To keep pace with the change, we need to develop the differentiated reference book that have a wider range of materials textbooks don't offer. Furthermore, to be utilized in history class it should be able to raise learners' historical awareness, function as a workbook for learners and facilitate learners' self-directed learning etc. Based on the ideas above, I focused on the followings in this paper. Firstly, I examined two kinds of appended map published by Kumsung Publishing and ChunJae Education respectively, which are authorized by government in 2010. Secondly, I analyzed the merits and demerits of the map books, considering their relevance to the history textbooks. Thirdly, I suggested the ways to make good use of the appended map in history class. As part of the efforts, I presented an example of teaching-learning plan for a unit. It is about 'Unit 4. Prince Regent Heungseon Daewongun, the one who wielded power for 10 years' included in 'Ⅲ. The Changes in Chosun Society and the Invasions of Western Powers', in which elements of the Korean history and those of the world history are integrated. I tried to find out the effective ways of teaching history with an appended map and give ideas on what should be considered in advance for more efficient teaching. Plus, the appended map should offer various materials that attract learners' attention and help to cultivate their historical thinking abilities.

        Although in recent years there have been studies about using historical pictures, they are still rather limited. They just focused on the theories or didn’t present obviously the results of applications of the materials to the history class. This paper aims to suggest how to use historical pictures in real class situations to help students to improve historical understanding and historical knowledge. This paper shows that teaching history by using historical pictures enhances students’ historical thinking ability, autonomy and motivation. The specific results of the experiment are as follows. First, “reading” the historical pictures, which is to figure out what their historical backgrounds are, increased students’ interests in the history class, stimulating their intellectual curiosity and making them take part in the class more actively. Second, class discussions developed students’ ability to “read” the pictures. The cooperative interaction between different levels of students led to the improvement in interpreting the pictures. Third, students’ historical thinking ability was built up through the process of grasping historical meaning, painter’s intention and historical contexts from the pictures. Fourth, students could learn the way to extract historical facts from the materials. In the process students’ historical understanding was developed, which means they could understand partially the perspective of a historian in dealing with historical phenomena. These visual historical materials can enable students to develop historical insights including critical and analytic abilities and problem-solving abilities by participating in the activities with the historical pictures. On the basis of the analysis, followings are suggested to provide the desire direction of history class using historical pictures. First, teachers should devise an annual lesson plan with specific purposes of introducing historical pictures. They should find the ways to desirably select historical pictures and perform teaching for the purposes. Second, teachers should pose proper questions to help students to interpret the pictures. Or they should encourage students to come up with their own questions about them and to follow the proper procedures of inquiry process. Third, students must be able to have access to various historical pictures in accordance with their level. As their level getting higher, high level materials should be offered.
