Bacillus cereus causes serious central nervous system infections, especially in immunocompromised patients. Successful treatment requires adequate antimicrobial concentrations in the cerebrospinal fluid; however, in some cases, achieving this with systemic treatment alone is difficult. We treated intractable B. cereus ventriculitis with intraventricular vancomycin, with no major adverse events.

최근 다양한 언어모델의 구축 및 발전으로 개체명 인식 시스템의 성능은 최고 수준에 도달했다. 하지만 이와 관련된 대부분의 연구는 데이터가 충분한 언어에 대해서만 다루기 때문에, 양질의 지도학습 데이터의 존재를 가정한다. 대부분의 언어에서는 개체 유형에 대한 언어의 잠재적 특성을 충분히 학습할 수 있는 지도학습 데이터가 부족하기 때문에, 종종 자원 부족의 어려움에 직면한다. 본 논문에서는 Masked language modeling 기반 언어 간 전이학습을 이용한 개체명 인식 방법론에 대한 분석을 수행한다. 이를 위해 전이를 수행하는 소스 언어는 고자원 언어로 가정하며, 전이를 받는 타겟 언어는 저자원 언어로 가정한다. 본 논문에서는 언어모델의 토큰 사전에 언어 독립적인 가상의 자질인 개체 유형에 대한 프롬프트 토큰을 추가하고 이를 소스 언어로 학습한 뒤, 타겟 언어로 전이하는 상황에서 제안하는 방법론에 대한 평가를 수행한다. 실험 결과, 제안하는 방법론은 일반적인 미세조정 방법론보다 높은 성능을 보였으며, 한국어에서 가장 큰 영향을 받은 타겟 언어는 네덜란드어, 한국어로 전이할 때 가장 큰 영향을 준 소스 언어는 중국어인 결과를 보였다.

In this paper, we report design, fabrication and characterization of the WBRM (Wide Band Receiver Module) for LADAR (LAser Detection And Ranging) application. The WBRM has been designed and fabricated using self-made APD (Avalanche Photodiode) and TIA (Trans-impedance Amplifier). The APD and TIA chips have been integrated on 12-pin TO8 header using self-made ceramic submount and circuit. The WBRM module showed 450 ps of rise time, and corresponding 780 MHz bandwidth. Furthermore, it showed very low output noise less than 0.8 mV, and higher SNR than 15 for 150 nW of MDS(Minimum Detectable Signal). To the author's knowledge, this is the best performance of an optical receiver module for LIDAR fabricated by 200 um InGaAs APD.

Objectives : The aim of this study was to investigate the relationship between the norepinephrine(NET) transporter T-182C polymorphism and anxiety-related traits in Korean adolescent females. Methods : One hundred sixty-nine Korean adolescent females were tested for the NET T-182C polymorphism by PCR based methods; anxiety-related traits were evaluated using the anxiety sensitivity index(ASI) and the trait form of the Spielberg State-Trait Anxiety inventory(STAI-T). Results : Scores of anxiety related traits were not different between genotypes. Comparison between T allele carries and non carriers revealed no significant difference. Conclusion : These findings suggest that the NET T-182C polymorphism is not associated with anxiety-related traits in Korean female adolescents.

Objects：This study investigated whether depression, anxiety and perceived parental rearing patterns of the conduct disorder patients are different from those of the normal control group. The correlations were also assessed between perceived parenting style and depression, anxiety, severity of conduct problems and age at onset of conduct disorder in adolescents with conduct disorder. Methods：Thirty hospitalzed patients who met the DSM-Ⅳ criteria of conduct disorder, and 30 normal control subjects completed self-report questionnaires containing the Children’s Depression Inventory(CDI), the State-Trait Anxiety Inventory for Children(STAIC) and the Parental Bonding Instrument(PBI). Results：In the conduct disorder group, the results were as follows：1) The mean scores of CDI and STAIC-T(Trait) were not significantly different from those of the control group, but STAIC-S (State) showed significantly higher scores. 2) Parenting style was perceved to be less caring and more overprotective than in the control subjects. 3) There were negative correlations between maternal care and CDI and between maternal care and severity of conduct problems. 4) There were positive correlations between maternal overprotection and STAIC-T(Trait). 5) There were no correlations between paternal rearing patterns and depression, anxiety, severity of conduct problems, or age at onset of conduct disorder. Conclusion：We failed to identify depression and anxiety as common comorbid disorders in conduct disorder. Parental rearing patterns are thought to be significantly negativistic in conduct disorder group. It is guessed that less caring and more overprotective rearing style of parents, especially of mothers, could have much influence on depression and anxiety, more severe conduct problems and earlier age at onset of conduct disorder in the adolescents with conduct disorder.

Water mist fire suppression system utilizes the fire suppression features such as cooling of fire source, dilution of ambient oxygen, and shielding of radiation heat with the evaporation of microscopic water droplets. The momentum of water mist is relatively lower than that of larger water droplet and the infiltration of water mist to the fire source is not effective. Contribution of evaporated water vapor is liable to decline to limited portion of fire source due to its light weight and sparse density. On the other hand, the cycling water mist pattern is expected to improve the penetration force of water mist as well as the air expelling capability with the stratified spray characteristics. At this paper, we present the analyzed fire suppression capability of intermittent water spray pattern by use of FDS which is computational fire dynamics fire model. We expect this analysis can support the basic concept to the development of the prototype of water mist nozzle.

The amount of dredging clay will be greatly increased by the eco-rive project and port development in Korea. Geotechnical engineers have thrown their efforts into the new ways for effective re-uses of the dredging clay such as the material for reclamation, and so on. However, very high initial water content and low strength causes unexpected difficulties in the aspect of trafficablility or time for consolidation. Therefore, the injection of cement stabilizer is used as one of ways to improve reclaimed ground. However, it also makes an argument by heavy metal from cement stabilizer. In this paper constant rate of strain consolidation test and normal consolidation test were performed to investigate behavior characteristics of the consolidation about soil-cement include lean mixed cement to reduce the environmental loads by the cement. The experimental results of consolidation characteristics about soil-cement include lean mixed cement influenced by mixing ratio. Especially it was observed that mixing ratio of 4%~6% leads not only the reduction of consolidation settlement, but time for consolidation.

The purpose of this study is to build a metadata set based on the semantic structure of the Korean studies research articles. For this purpose, we analyzed the related researches which suggested the semantic structure of the research articles, categorized the concepts of author keywords of the Korean studies research articles, and drew the metadata set of 16 elements from the results of the analysis and the categorization. The significance of this study is that it propose a semantic metadata configuration methodology which can reflect the scholarly sense-making of researchers in Korean studies. Especially, this study is significant because it reflects the keywords which was given by the actual researchers to examine the content characteristics of the Korean studies research articles.

This paper describes the electron transport characteristics in SF6 gas calculated for range of E/N values from 150~ 800[Td) by the Monte Carlo simulation and Boltzmann equation method using a set of electron collision cross sections detennined by the authors and the values of electron swarm parameters are obtained by TOF method. The results gRined that the values of the electron swarm parameters such as the electron drift velocity, the electron ionization or Rttachment coefficients, longitudinal and transverse diffusion coefficients agree with the experimental and theoretical for a range of E/N. The properties of electron avalanches is concerned electron energy non--equilibrium region. The electron energy distributions function were analysed in sulphur hexafluoride at E/N : 500~800[Td) for a case of non-equilibrium region in the mean electron energy. The validity of the results obtained has been confilll1ed by a TOF method.

Background : Iron deficiency anemia(IDA) is a very common condition, and its underlying causes are diverse. Gastrointestinal blood loss, pregnancy, menorrhagia are known as common causes of IDA. However, especially in the IDA case of unknown origin, we must consider the culture specific cause of IDA as a possible cause of IDA. As I found an unusual cause of IDA related to a cultural behavior, I would like to report two cases of IDA occurred by negative therapy in Korea. It is possible to explain these cases by explanatory model. Case 1 : With a chief complaint of dyspnea, a 27-year-old woman visited our clinic. She had multiple treatment histories of negative therapy for her psoriasis. The blood loss during this procedure is the cause of present IDA. Case 2 : A 70-year-old man visited our clinic complaining of anorexia and dizziness. The history of treatment showed that he had an IDA 9 month ago. The IDA developed again because of repeated negative therapy after previous treatment of IDA. He has used the negative therapy intermittently to treat tinea pedis for 5 years. Conclusion : We must consider the negative therapy as a possible cause of IDA in Korea.
