  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.

The feasibility of the up- and down-flow constructed wetland was examined fur rural wastewater treatment in Korea. Many constructed wetland process was suffered from substrate clogging and high plant stresses because of long term operation. The up- and down-flow constructed wetland process used porous granule materials (charcoal pumice : SSR=10:20:70) for promoting intake rate of nutrient to plant, and especially flow type was designed continuously repeating from up-flow to down-flow. $BOD_5$ and SS was removed effectively by the process with the average removal rate being about 75% respectively. The wetland process was effective in treating nutrient as well as organic pollutant. Removal of TN and TP were more effective than other wetland system and mean effluent concentrations were approximately 7.5 and $0.4mg\;L^{-1}$ which satisfied the water quality standard for WWTPs. The treatment system did not experience any clogging or accumulations of pollutants and reduction of treatment efficiency during winter period because constructed polycarbonate glass structure prevented temperature drop. Considering stable performance and effective removal of pollutant in wastewater, low maintenance, and cost-effectiveness, the up- and down-flow constructed wetland was thought to be an effective and feasible alternative in rural area.

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.

A Parallel Algorithm of Davidson Method for Solving and Electomagnetic Problem

김형중,주욱,Kim, Hyong Joong,Zhu, Yu Kangwon National University 1997 産業技術硏究 Vol.17 No.-

The analysis of eigenvalue and eigenvector is a crucial procedure for many electromagnetic computation problems. Although it is always the case in practice that only selected eigenpairs are needed, computation of eigenpair still seems to be a time-consuming task. In order to compute the eigenpair more quickly, there are two resorts: one is to select a good algorithm with care and another is to use parallelization technique to improve the speed of the computing. In this paper, one of the best eigensolver, the Davidson method, is parallelized on a cluster of workstations. We apply this scheme to a ridged waveguide design problem and obtain promising linear speedup and scalability.

학교 신체검진 상 우연히 발견된 제2형 막증식성 사구체신염 1예

막증식성 사구체 신염은 메산지움의 증식과 사구체 모세혈관의 비후를 동반하는 진행성 신질환으로 병리학적 소견에 따라 1, 2, 3형으로 분류할 수 있다. 이 질환은 일차성 사구체신염의 약 2%가량을 차지하는데, 대개의 경우 만성적으로 진행하는 경과를 보이며 다른 사구체신염에 비하여 신기능 소실로 진행하는 경우가 많지만 효과적인 치료법이 정립되어있지 않고 다양한 치료가 시도되고 있다. 학교 집단신체검사에서 소변검사가 포함되기 시작하면서 제1형 막증식성 사구체신염은 수차례 보고되었고 이들에 대한 조기 치료가 신질환의 진행을 늦추는데 효과적인 것으로 알려져 있는데 반해, 제2형 막증식성 사구체신염이 학교 집단신체검사에서 발견된 예는 현재까지 국내에서 보고된 바 없기에 문헌고찰과 함께 보고하는 바이다. Type II membranoproliferative glomerulonephritis (MPGN) is characterized by thickening of the glomerular basement membrane owing to electron-dense deposits on electron microscopy. We experienced a case of type II MPGN in a child presenting with proteinuria, hematuria on school urinary screening tests. He had been treated with losartan and enalapril. This is the first case report of type II MPGN detected by school urinary screening tests in Korea. Thus we report a case of 10-years-old male with type II MPGN with a review of brief literature.

논문 - 이동저수지 유역의 수질 특성 및 항목간 상관관계 분석

김형중,함종화,김동환,홍대벽,Kim, Hyung-Joong,Haam, Jong-Hwa,Kim, Dong-Hwan,Hong, Dae-Byuk 한국관개배수위원회 2011 한국관개배수논문집 Vol.18 No.2

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.
