Shin, Myoung-Ho,Hwang, Hyun-Seob,Lee, In-Bok,Seo, Young-Ho,Kim, Min-Kyun The Korean Society for Applied Biological Chemistr 2013 Applied Biological Chemistry (Appl Biol Chem) Vol.56 No.6

Halophyte community was established for dust prevention in Saemangeum reclaimed land from 2006 to 2008. In the present study, the functions of halophyte community were examined on-site in aspects of dust collection and nutrient absorption. In dust collection experiments, total suspended particulate (TSP) decreased through transplanted halophyte community and the reduction effect continued to 50 m leeward, which was 5.6 times of plant height. TSP reduction behind in-situ halophyte communities amounted to 25.6% on seven-monthly average. TSP collected within four halophyte communities varied among halophytic species in the field. Harvested in the reclaimed land, halophytic samples contained significant amount of nitrogen (0.84 to 1.71% of dry weight), $P_2O_5$ (0.05 to 0.21% of dry weight), and $Na^+$ (0.08 to 3.20% of dry weight). On the basis of halophyte community area in 2006, the amount of total nitrogen, $P_2O_5$ and $Na^+$ absorbed by Suaeda asparagoides was estimated up to 404,000, 47,000, and 498,000 kg, respectively. These results implied that halophyte communities are capable of both collecting significant dust particulates and absorbing of nitrogen, phosphorus, and sodium in the reclaimed land.

센서 네트워크에서의 데이타 수집을 위한 라우팅 기법

송인철(In Chul Song),노요한(Yohan Roh),현동준(Dongjoon Hyun),김명호(Myoung Ho Kim) 한국정보과학회 2006 정보과학회논문지 : 데이타베이스 Vol.33 No.2

연속 질의는 센서 네트워크에서 일반적으로 사용되는 질의로서, 한 번 요청되면 일정한 주기로 여러 번 실행되어 그 질의의 결과를 베이스 스테이션으로 모은다. 이것은 지속적으로 많은 메시지 전송을 유발시키므로 베이스 스테이션으로 데이타를 모으는 데 드는 통신 비용을 줄이는 것이 중요하다. 센서 네트워크에서 네트워크내 프로세싱 기법은 중간 노드에서 집계 질의의 결과 데이타들에 대해 부분 집계를 수행하거나 그 데이타들을 하나의 메시지에 담아 보냄으로써 메시지 전송 횟수를 줄이며, 이것은 결국 통신 비용을 줄인다. 본 논문에서는 질의별로 구성되는 라우팅 트리인 질의 기반 라우팅 트리(Query Specific Routing Tree: QSRT)를 제안한다. QSRT의 핵심 아이디어는 네트워크내 프로세싱의 기회를 최대화하는 것이다. QSRT는 질의가 전달되는 과정을 통해 생성되며, 질의의 결과들이 베이스 스테이션으로 전달되는 도중 가능한 한 빨리 서로 만나게 만들어 부분 집계 및 패킷 합병의 기회를 최대화시킨다. 수행된 실험의 결과는 제안된 QSRT가 기존의 라우팅 트리보다 메시지 전송 횟수를 18% 이상 줄일 수 있음을 보여 준다. Once a continuous query, which is commonly used in sensor networks, is issued, the query is executed many times with a certain interval and the results of those query executions are collected to the base station. Since this comes many communication messages continuously, it is important to reduce communication cost for collecting data to the base station. In sensor networks, in-network processing reduces the number of message transmissions by partially aggregating results of an aggregate query in intermediate nodes, or merging the results in one message, resulting in reduction of communication cost. In this paper, we propose a routing tree for sensor nodes that qualify the given query predicate, called the query specific routing tree(QSRT). The idea of the QSRT is to maximize in-network processing opportunity. A QSRT is created seperately for each query during dissemination of the query. It is constructed in such a way that during the collection of query results partial aggregation and packet merging of intermediate results can be fully utilized. Our experimental results show that our proposed method can reduce message transmissions more than 18% compared to the existing one.

김인수(In-Soo Kim),정명호(Myoung-Ho Jeong),한재복(Jae-Bok Han),장영일(Young Ill Jang),장성주(Seong-Joo Jang) 한국콘텐츠학회 2013 한국콘텐츠학회논문지 Vol.13 No.12

약물방출 스텐트 (drug-eluting stents, DES)는 일반금속 스텐트에 비하여 재협착을 현저하게 줄었지만, DES의 구조적인 특성으로 인한 스텐트 혈전증 (stent thrombosis, ST)이 증가한다고 알려져 있다. 혈전증 유형의 정의는 Early ST ; (EST)은 30일 이내, Late ST ; (LST)은 31일 이상에서 1년 이내 그리고 Very late ST ; (VLST)은 1년 이상으로 분류 하였다. 스텐트 세대별 (시장 출시와 스텐트 디자인, Polymer 향상에 따른) ST발생빈도, 임상 양상 및 예후를 알아보았다. 2003년 6월부터 2013년 6월까지의 전남대학교병원 심혈관센터에서 경피적 관상동맥 중재술을 시행 받은 10,273명 중 ST 발생은 134명(1.30%) 이었다. 세대별 발생빈도는 1세대에서 81명 (0.79%)으로 높았으며, 세대별 ST 유형은 1세대에서는 VLST의 발생률이 높았고 (p=0.002), 2세대에서는 EST와 LST의 발생률이 높았지만 (p=0.025), 3세대에서는 유의한 차이가 없었다(p=0.278). ST로 인하여 사망한 14명은 EST 10명 (18.2%), LST 2명(8.3%), VLST 2명 (3.6%)로서 EST에서 사망률이 높았다 (p=0.042). DES 시술 후 발생하는 ST는 1.3%이였고, VLST는 1세대 스텐트에서 많았으며, 입원 중 사망률은 EST에서 높았다. Stent thrombosis after successful drug-eluting stent(DES) implantation has been reported in around 1% of patients in clinical trials. However, the increased risk of ST associated with DES remains a matter of concern. From 1 June 2003 to 30 June 2013, we investigated clinical characteristics, in-hospital outcomes in 10,273 patients who underwent percutaneous coronary intervention in the Heart Center of CNUH. Overall incidence of ST was 1.30% (134 patients). The incidence of ST according to the stent generations and the timing of ST (n= total, early vs. late vs. very late) were 0.79% (n =81, 26 vs. 12 vs. 43) in first-generation, 0.38% (n=39, 21 vs. 9 vs. 9) in second-generation and 0.14% (n=14, 8 vs 3 vs. 3) in third-generation, (p=0.70). The mortality from ST was significantly higher in early ST group compared to the late and very late ST groups (18.2% vs. 8.3% vs. 3.6%, p=0.042). Overall incidence of ST after DES implantation was 1.30% (134 patients). The in-hospital mortality was significantly higher in early ST group compared to the late and very late ST groups.

강철인,김성한,방지환,김홍빈,박상원,최영주,오명돈,김의종,최강원 대한감염학회 2003 감염과 화학요법 Vol.35 No.2

목적 : 본 연구는 ESBL을 생성하는 K. pneumoniae에 의한 균혈증 환자에서 감염의 위험 인자 및 치료 결과를 알아보고자 시행하였다. 방법 : 1998년 1월부터 2002년 4월까지 혈액 배양 검사에서 동정된 K. pneumoniae를 대상으로 NCCLS guidelines과 이중 디스크 확산법(double-disk diffusion test)을 이용하여 ESBL 생성 여부를 확인하였다. ESBL 생성 균주에 의한 균혈증 환자 60명(환자군)에 대해 ESBL을 생성하지 않는 균주에 의한 균혈증 환자들(대조군)을 연령, 성별, 균혈증 발생 시점을 고려하여 1:2 또는 1:3으로 배정하였다. 총 159명의 대조군을 선정하였고 후향적인 환자-대조군 연구를 시행하였다. 결과 : 환자군과 대조군 사이에 연령, 성별, APACHE Ⅱ score, 주된 감염 부위의 유의한 차이는 없었다. ESBL을 생성하는 K. pneumoniae에 의한 균혈증이 발생할 독립적인 위험 인자에는 요관 삽입, 균혈증 발생 이전 72시간 동안 침습적인 시술을 받은 경우, 균혈증 발생 이전 30일 동안 투여받은 항생제 개수가 있었다. 초기 항생제 치료 72시간 후의 반응을 평가하였을 때, 완전 반응(complete response)은 대조군에서 더 많았고(13.3% vs. 40.3%, P<0.001), 치료 실패(treatment failure)는 환자군에서 더 많았다(33.3% vs. 11.9%, P<0.001). 7일 사망률은 환자군에서 20% (12/60), 대조군에서 15.6% (25/159)이었고(P=0.451), 30일 사망률은 환자군에서 30% (18/60), 대조군에서 24.5% (39/159)이었다(P=0.410). ESBL 생성 균주에 의한 균혈증이 있는 환자들에서 최종 항생제 치료가 부적절했던 환자들을 제외하고 30일 사망률을 분석하였을 때 효과적인 항생제 치료의 지연은 사망률을 높이지 않았다(11.1% vs. 9.1%, P=1.000). 결론 : ESBL을 생성하는 K. pneumoniae에 의한 균혈증이 있는 환자에서 초기 항균제 치료 72시간 후의 치료 반응률은 낮지만 사망률은 유의하게 증가하지 않았다. 원인균이 동정된 후 최종 치료 항생제의 선정이 적절하다면 초기에 효과적인 항생제 투여의 지연은 사망률을 유의하게 증가시키지는 않았다. Background : This study was conducted to evaluate risk factors for infection and treatment outcome of bloodstream infection due to extended spectrum β-lactamases(ESBL)-producing K. pneumoniae. Methods: ESBL production was evaluated by NCCLS guidelines and/or double-disk synergy test in K. pneumoniae blood isolates stored from January, 1998 to April, 2002. Sixty patients with bloodstream infection due to ESBL-producing K. pneumoniae (case patients) were compared with 159 matched control patients with bloodstream infection of non-ESBL-producing K. pneumoniae. Retrospective case-control study was performed. Results : There were no significant differences in age, sex, APACHE Ⅱ score, and the primary site of infection between the case and control groups. In multivariate analysis, significant independent risk factors associated with bloodstream infection due to ESBL-producing K. pneumoniae were urinary catheterization, invasive procedure within previous 72 hours, and the number of antibiotics administered within previous 30 days. In clinical response at 72 hours after initial antibiotic treatment, complete response rate was higher in the controls (13.3% vs. 40.3%, respectively, P<0.001), however, treatment failure rate was higher in the cases (33.3% vs. 11.9%, respectively, P<0.001). Overall 7-day mortality rates in the cases and the controls were was 20% (12/60) and 15.7% (25/159) (P=0.451), respectively, and overall 30-day mortality rates were 30% (18/60) and 24.5% (39/159), respectively (P=0.410). When the patients with bloodstream infection of ESBL-producing organism were evaluated and the patients who received inadequate definitive antibiotic treatment were excluded, delayed effective antibiotic treatment was found to be not associated with higher mortality. Conclusion : In patients infected with ESBL-producing K. pneumoniae bacteremia, clinical response rate at 72 hours after antimicrobial therapy was lower, but the increase of mortality rate was not significant. Delayed effective antibiotic treatment was not associated with higher mortality, when definitive appropriate antibiotic treatment was prescribed.

The results of the examination for the new science curriculum shows that the selection and arrangement of the contents of the teaching subjects is reasonable, but that the contents is difficult and the quantity of the subjects is abandant in both side of teaching and learning is dominant opinion. The results of the sequence analysis of the teaching contents are as follows: (1) the selection of the fundamental concepts, the level of teaching in primary and junior high school, and the sequence of the contents are of no gross faults. (2) The sequence of the "Waves" included the properties of light is cut off, because they do not deal with the waves in the energy concept in junior high school. (3) The unit, "Magnetic Effect of a Current" is dealt with in interaction unit in primary school, and on the other hand it is dealt with in energy unit in junior high school. So, there is room for examination in magnetic effect of current from a viewpoint of the concept development and sequence maintenance. Next, we discussed the theoretical background for the formation of sequence and especially have set up the hierarchy of the inquiring process, in the viewpoint of organizing the contents and techniques dealt with in inquiring activities. And, on the basis of a survey of public opinion, analysis of sequences, and general theory of formation of sequence, we proposed the general rule for organizing the sequence of the concepts and the process-skills between the primary and the junior high school, and for organizing the sequence of the seience curriculum in itself. On the basis of these discussion, we have selected some unit and framed the teaching programme which will serve as a good reference to the practical teaching. We hope that a large number of teachers put the contents proposed in this paper and teaching programme organized process-skills into practical use, and they research and practice the various teaching techniques continuously in order to reach to educational purpose of the new science curriculum.
