  This research references existing research for bard Kim-rip and his poem, examined his work tendency in detail. His work can divide to satirical poem, Hangul poem, word amusements(破字戱詩), descriptive poem, love poem, spiritual being poem(詠物詩), animal(insect) poem etc. Recognized his writer mind through his work world that did literature activity through poem of various genre in addition.<BR>  Kim-rip was Andong-Kim"s descendants who is best nobility pedigree, but his parentage fell because of Hong-gyeongrae"s rebellion. He satirical inconsistency of society system and hypocrisy of control class fluently present age through his poem. It is as result that his surrounding environment that could not but give up own learning and knowledge that learn to take part in politics on groundwork of these work is reflected.<BR>  Critical sight for Kim-rip"s satire and jest, hypocrisy of control class is expressed well at his Hangul poem and word amusements. These work that mix Chinese character and Hangul properly, express subject by pronunciation sometimes, to Chinese character meaning sometimes. He understood by principal parts genre of Hangul poem and word amusements that a maid of honor and peoples enjoyed and Chinese poem that the nobility class enjoys the age.<BR>  Kim-rip created descriptive poems that praise the Korean famous mountain and nature sceneries that witness by oneself through life of wandering beautifully. Also, he created much love poems that exchange with kisaeng or various women for tiring wandering period. His descriptive poems showed superior artistic talent of delicate and brand new scenery delineation with sense of beauty which is polished for nature. His love poems sought sense of freedom about instinctive love of human which was prohibited in restraint of feudalism.<BR>  Spiritual being poem, animal(insect) poem used thing which can find easily in our surrounding to site of work. For example, there were the domestic animals such as a dog and rooster, parasite such as a louse and flea, life articles such as chamber pot, brazier, pipe and so on. He escapes conservative view of the world which the nobility culture has and expressed civilianization"s life in his work. Such his work tendency produced result that only the nobility class magnifies Chinese poem that enjoyed by public"s life.

Fallow paddy areas have been increased due to the import of cheap agricultural product, and the unbalance between farming cost and rice price since 1990. The increasing fallow paddy area needs to be protected from the devastation by weed breeding for the re-cultivation. In this study, two fallow paddy fields managed with different water depth were selected for monitoring and analysing of water quality, water balance and plant body change. The managed fallow paddy fields were more effective in water quality purification and plants growth control than non-managed fallow paddy fields. And the fallow paddy field managed with some degree of water depth was the most effective field in terms of weed control.

논문 - 이동저수지 유역의 수질 특성 및 항목간 상관관계 분석

This study was carried out to analyze characteristics of water quality and correlation among water quality parameters in Idong reservoir used for agricultural water. The pH and concentrations of DO, SS, BOD, COD, TP, Chl-a in Idong reservoir almost met the water quality standards for agricultural water, but TN concentration exceeded the water quality standards for agricultural water. All of water quality items had no significant difference between horizontal points at 95% confidence level and the Idong reservoir was possible to be treated as the single water body. As NIP ratio of the Idong reservoir is 52, TP is a limiting nutrient salt. As TN exceeds the water quality standards, it is required to preserve TP below current state to prevent water bloom by eutrophication. Therefore, reduction of phosphorus from the watershed is necessary for controlling the eutrophication of Idong reservoir.

Purpose In this study, we performed in vivo disease model animal experiments to validate the MREIT technique in terms of its capability to produce a conductivity contrast corresponding to brain ischemia and abscess. Methods Injecting 5 mA imaging currents into the head of an anesthetized dog, we collected induced magnetic flux density data using a 3T MRI scanner. Applying the harmonic Bz algorithm to the data, we reconstructed scaled conductivity images providing conductivity contrast information. To investigate any change of electrical conductivity due to brain diseases of ischemia and abscess, we scanned an animal with such a regional brain disease along with a separate prior scan of the same animal having no disease model. Results In the brain ischemic region, conductivity images show a significantly decreased contrast. The conductivity images of brain abscess show a significantly increased contrast, which is not apparent in the normal brain. Conclusions The results indicate that MREIT conductivity images provide meaningful diagnostic information that is not available from other imaging modalities. We suggest further animal imaging experiments with numerous disease models to support clinical significance of the MREIT conductivity imaging method.

In this paper, channel propagation path loss was measured in building corridors for frequency bands of 3.7 GHz and 28 GHz, which are used in 5G mobile communication, and compared and analyzed with CI (Close-In) and FI (Floating-Intercept) channel models. To measure the propagation path loss, the measurement was performed while moving the receiver (Rx) from the transmitter (Tx) by 10 m. As a result of the measurement, the PLE (Path Loss Exponent) values of the CI model at 3.7 GHz and 28 GHz were 1.5293 and 1.7795, respectively, and the standard deviations were analyzed as 9.1606 and 8.5803, respectively. In the FI model, 𝛼 values were 79.5269 and 70.2012, 𝛽 values were -0.6082 and 1.2517, respectively, and the standard deviations were 5.8113 and 4.4810, respectively. In the analysis results through the CI model and the FI model, the standard deviation of the FI model is smaller than that of the CI model, so it can be seen that the FI model is similar to the actual measurement result.

To provide the information necessary for the insurance medicine management plan, price discount rates among the insurance medicines were studied. A total of 2,107 items of insurance medicine of which prices were discounted via governmental inspections of real transactional process of insurance medicine were analysed. The conclusions are as follows; 1. Among the variables relevant to the characteristics of manufacturers, price discount rates of insurance medicines were statistically significant with production rankings of manufacturers, incorporation year, existence of investments by foreign corporation, existence of a research institute, and enrollment in the exchange. And among the variables relevant to the properties of medicines, the number of enrolled items which have the same components, classification, the date of new enrollment, the sales of items, and the number of raw materials in the items were statistically significant. 2. Stepwise multiple regression was done to identify the factors which affect the price discount rates of insurance medicines. The number of enrolled items which have the same components, production rankings of manufactures, classification number (medicines for function of tissue cells), incorporation year(1940-1949), existence of investments by foreign corporations, classification number (anti-germ medicines), number of raw materials In the items, the sales of items, and medicines whose major objective is not treatment were significant variables and the $R^2$-value for these variables was 21.2%. Considering all of the above results, for management of insurance medicines, it seems important that the real transactional prices of insurance medicines should be identified systematically, focusing on the properties which affect the price discount rates of insurance medicines.
