Use of SiPM has been considered as an alternative to PMT, because of its compact size, low-operating voltage, non-sensitive to electromagnetic, low costs and so on. The main limitation for the use of SiPM is due to its small sensitive area compared to PMT that limits the light collection, and therefore the sensor energy resolution. In this article we studied the effect of increasing the number of SiPM by connecting them in parallel to increase the active detection area. This allowed us to compare the different energy resolution measurements. ¹³⁷Cs has been selected as reference to study the energy resolution for 662 keV gamma-rays. Another investigation was to compare the minimum detectable gamma energy under various SiPM configurations. It has been found that the use of 4 SiPM arrays can greatly improve the energy resolution up to 4% than only one SiPM array, meanwhile use of more than 2 SiPM arrays does not increase the energy resolution significantly. Thus we can conclude that for a large area of cylindrical scintillator (3 × 3 inches), the use of SiPMs are limited to a certain number or certai active area depending on the commercial SiPMs, and its cost should be less than traditional PMT for the cost-effective and compact size considerations. It is well known that the gain of SiPM varies with temperature. In this article, we also calibrated gain to guarantee the same position of photoelectric peak in response of different temperatures.

단차로 하이패스시스템의 지 정체로 인한 교통 혼잡, 안전사고, 유지보수 등 매년 발생하는 문제를 해결하기 위해 무정차 다차로 고속주행기반 시스템의 개발이 필요하게 되었다. 하이패스 통신시스템은 단차로 환경에서 선입선출 방식이므로, 다차로 환경에서 발생하는 군집주행 및 차로전환 등 다양한 주행패턴을 처리할 수 없다. 본 논문에서는, 기존의 하이패스 단말기를 수용하면서 다차로 주행이 가능한 통신시스템을 개발했다. 능동형 RF/IR 통신 안테나를 이용해 중첩 영역은 넓히고, 오류범위를 최소화 하는 기술을 구현했다. 체험도로를 다차로 실 환경처럼 구축하여 테스트한 결과 하이패스시험기준을 통과했을 뿐 아니라, 속도별, 차로별, 차로전환별 주행시험 및 단말기 위치별 시험 결과 통신 정확도도 99.9%로 하이패스시스템의 성능을 만족했다. 무정차 다차로를 위한 통신시스템은 향후 고속도로 및 유료도로에서도 사용할 수 있을 뿐 아니라, 주차장에서도 활용할 수 있을 것으로 기대한다.

ICT 기술의 혁신적인 발전에 따라 해커의 해킹 수법도 정교하고 지능적인 해킹기법으로 진화하고 있다. 이러한 사이버 위협에 대응하기 위한 위협탐지 연구는 주로 해킹 피해 조사분석을 통해 수동적인 방법으로 진행되었으나, 최근에는 사이버 위협정보 수집과 분석의 중요성이 높아지고 있다. 봇 형태의 자동화 프로그램은 위협정보를 수집하거나 위협을 탐지하기 위해 홈페이지를 방문하여 악성코드를 추출하는 다소 능동적인 방법이다. 그러나 이러한 방법도 이미 악성코드가 유포되어 해킹 피해를 받고 있거나, 해킹을 당한 이후에 식별하는 방법이기 때문에 해킹 피해를 예방할 수 없는 한계점이 있다. 따라서, 이러한 한계점을 극복하기 위해 사이버 거점을 식별, 관리하면서 위협정보를 획득 및 분석하여 실질적인 위협을 탐지하는 모델을 제안한다. 이 모델은 방화벽 등의 경계선 외부에서 위협정보를 수집하거나 위협을 탐지하는 적극적이고 능동적인 방법이다. 사이버 거점을 활용하여 위협을 탐지하는 모델을 설계하고 국방 환경에서 유효성을 검증하였다.

Objectives : GunRyeong-Tang(GRT) is a traditional herbal prescription that combines Oryeongsan and Sagunja-tang. This study employed network analysis methods on the components of GRT and target genes related to diabetes complications to predict the improvement effects of GRT on diabetes complications. Methods : The collection of active compounds of GRT and related target genes involved the utilization of public databases and the PubChem database. We selected diabetes complication-related genes using GeneCards and confirmed their correlation through comparative analysis with the target genes of GRT. We constructed a network using Cytoscape 3.9.1 and conducted topological analysis. To predict the mechanism, we performed functional enrichment analysis based on Gene Ontology (GO) biological processes and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathways. Results : Through network analysis, 234 active compounds and 1361 related genes were collected from GRT. A total of 9,136 genes related to diabetes complications were collected, and 1,039 target genes overlapping with the components of GRT were identified. The core genes of this network were TP53, INS, AKT1, ALB, and EGFR. In addition, GRT significantly reduced the H9c2 cell size and the expression of myocardial hypertrophy biomarkers (ANP, BNP), which were increased by high glucose (HG). Conclusions : Through this study, we were able to predict the activity and mechanism of action of GRT on diabetes and diabetic complications, and confirmed the potential of GRT as a treatment for diabetes complications through the effect of GRT on improving myocardial hypertrophy for diabetic cardiomyopathy.

These days, Emotional Design is on the sustainable development through activity study thogh, until now, the study proceed too far with Sensibility Ergonomics applied to SD. However, on this paper, the study would be make progress through GSD that it applied to Verb. For this reason, applied to Emotional Design consideration of theory through JOAN MEYERS-LEVY's papaer titled "The Influence of Ceiling Height", Laban Movement Analysis and Aspect of Semiotics and then judgement of GSD would be make progress through experiment to collection of Emotional Vocabularies and evaluation of body movement. There is a method of analysis by using statistical program such as SPSS 18.0 and it would have validity of analysis. Here is a result of this study. According to heights of ceiling types(2.4M, 3.0M) there are differences between behavior of Figure Attachment, Emotional Vocabularies of the event and Body Movement. While the Figure Attachment has a tendency to restricted scope, CH has a tendency to make attachment within the scope. You could see the Negative Adjective for Emotional Vocabularies at CL and the Positive Adjective ranges at the CH. Basic body movement for passive, 'moving' and 'stretching' as shown at CL more than the CH. For active movement which has purpose, 'moving the weight' and 'stretching' as shown at CH more than at CL.

Euthanasia have received considerable attention recentely in medical literature, public discussion, and proposed state legislation. Almost all the discussion in this area has focused on the role of physicians. However, nurse may be in special position to understand the wishes of patients and to act on this understanding. Purpose of this study is to identity the meaning of euthanasia in terminal ill patients on the nurses' veiw. Forcused interveiw design was used to data collection The data were analyzed by semantic analysis, and analysis of the data resulted in identification of 14 categories representing the meaning of euthanasia. 1. The meaning of supported euthanasia is 'free of suffering', 'difficulty of economic status', 'right of patient and family', 'dignity of death', 'organ transplant', 'social legislation'. 2. The meaning of opposited euthanasia is 'artificial death', 'value of life', 'uncertainity', 'guilt feeling' 3. The meaning of care in terminalily ill patients is 'avoidance', 'powerlessness'. 'apathy'. 'passive attitude'. The policy debate about professional roles in action that end of lives of patients must be extended nurses. Nurses must take an active role in discussion and definition of acceptable practice at the end of life.

Purpose: This research investigated the daily experiences of patients' lives to develop a formal theory that explains the lives of schizophrenic patients. Method: A grounded theory method(Strauss & Corbin, 1998) guided the data collection and analysis. Thirteen patients who were diagnosed with schizophrenia in regional communities participated. Result: The experiences of chronic schizophrenic patients are defined as "escaping from a fallen mine" comparing their suffering to that of entrapped miners trying to free themselves from a collapsed mine tunnel with much difficulty and without hope. In observing participant's time lines of having lived with chronic schizophrenia, it advances with 'surrender', 'collapse', 'reaching out', 'rising', 'preparing to spring up', and 'starting anew'. Conclusion: The results of this study indicate that the experience of a chronic schizophrenic patient is like that of a miner caught under a fallen mine channel, who, without external help cannot escape the depths 'Of the mine, but at the same time must have conviction and hope of rescue and avert fear to cooperate with outside help. The result indicates that family members, doctors and nurses as well as an institute's persistent and active support is most critical for the patient's adjustment to social life.
