Although large hydraulic facilities such as sea dike, breakwater bank and river bank, can protect a lot of lives and various industrial facilities from flood. The extreme weather events including changes in land use, localized heavy rains, extraordinary floods and earthquakes; rapid water discharge from upstream dams; and dam destruction may cause inundation damage like flood flow and debris flow. Such disasters by outburst floods result in not only loss of mass lives and property but also different social problems. In this regard, it is essential to establish flood forecasting, warning and evacuation strategy for proper flood measures against such disasters. Organizations in charge of controlling reservoirs and sea dikes have developed and operated Emergency Action Plan (EAP) by scenarios of emergency situations caused by floods exceeding the design flood amount or unpredictable reasons such as earthquakes.EAP classifies emergency levels issued for emergency situations including collapse of reservoirs and sea dikes into 4 stages-Attention (Blue), Caution (Yellow), Alert (Orange), Serious (Red) - to determine and respond to the symptom by situation. For areas where EAP for sea dikes has been established, the development of emergency situations or countermeasures are classified, while there is no index to separate them. In this case, if a manager conducts the phased measures with only “forecasting” in the situation stage, they are highly likely to have limitations to their active responses. This research aims to perform hydraulic and hydrologic safety review on sea dikes according to inflow of extraordinary floods from upstream of sea dikes and tributaries. Changes in water level flowing into the lake according to flood amount by frequency is used to investigate if it can be utilized as a disaster management index for EAP for sea dikes. For this, EAP index is developed by simulating flood level changes and time to reach flood level at the point of selected sea dikes from 100, 200 and 500-year and PMF flood amounts centering around the sea dikes. Targeting Saemangeum Lake, the study set the range required for numerical model, entered model composition and data using Delft3D numerical analysis model, verified the credibility of the model through calibration and established operational conditions of the model. Assuming that Saemangeum Master Plan had been completed, the study also conducted comprehensive operations. For inflow of floods by each frequency according to management water level in the lake, time to reach the flood level and flood stage were simulated. EAP index was established using the flood level and travel time. If the initial stage among the emergency levels, ‘Attention,’ was set as 『from extraordinary flood to management water level EL-1.5m』, it would be beneficial to respond to initial disasters. Also, it would be easier to set ‘Caution’ as 『from management water level EL-1.5m to management flood level inside the lake EL+1.5m』; ‘Alert’ as 『from management flood level inside the lake EL+1.5m to riprap protection flood level inside the bank』; and ‘Serious’ as 『flood level over riprap protection inside the bank (Mangyeong EL+4.5m, Dongjin EL+2.5m)』 for responding to initial disasters. The research aims to provide sea dike operators with more accurate information by presenting index by emergency situation stage. The result, as hydraulic and hydrological data on flood level, travel time, etc., is expected to be useful for sea dikes with or without EAP as a response index required for disaster management of sea dikes.

One-dimensional (1D) nanostructure systems, such as nanowires, nanorods, and nanotubes have fascinating distinctive features. These nanostructures are essentially ideal building blocks for electronic, photonic devices, and sensor applications. Among semiconductor nanowires, especially silicon nanowires have been drawn much interests due to their scientific and technological properties. These can be used as nanoscale devices such as field-effect transistors (FETs), light-emitting diodes (LED), solar cells, gas-sensors, and thermoelectric devices, etc. These nanostructures can also be used in the field of bio-medical applications because of excellent biocompatibility. In this report, we studied immunocyte separation and neuron-chip applications with silicon nanowire. Also we developed unit processes, a modulation of doping concentration and a formation of nickel silicide for high performance silicon nanowire FET. First of all, we have synthesized the silicon nanowires using a vapor-liquid-solid method in a chemical vapor deposition (CVD) quartz-tube furnace with silicon tetrahydride (SiH4) as a silicon precursor and gold as a catalyst. The diameters of the silicon nanowire were normally in the range of 150 ~ 300 nm and the lengths are in the range of 3 ~ 10 um with high dense arrays. We also have discussed some of the material characterizations such as field-emission scanning electron microscopy (FE-SEM), high-resolution transmission electron microscopy (HR-TEM), and energy-dispersive X-ray spectroscopy (EDS). Second, we developed unit processes, a modulation of doping concentration using ion implantation and a formation of nickel silicide for lower contact resistance at silicon-metal interface. We also performed a SILVACO simulation for optimization of ion implantation process. Then, we have demonstrated p-type silicon nanowire FET prepared by B-ion implantation with a dose of 1 ? 103 ions/cm2 and an energy of 10 keV, a carrier mobility and a concentration were estimated to be 2.9 cm2/V∙s and 1.1 ? 1019 /cm3 respectively. Using KOH solution for wet-etching process, we synthesized less than 100nm silicon nanowire diameter, performed a formation of nickel silicide, and studied its material characterization by FE-SEM and EDS analysis. Third, we have synthesized silicon nanowire arrays on the patterned silicon substrate for immunocyte separation. Then, a streptavidin, an APTES, a GA were coated continuously on the patterned silicon nanowire arrays. A CD4+ T cell was separated from a splenocyte in a mouse spleen using the streptavidin modified silicon nanowire arrays. Finally we estimated up to 93 % separation yield of the CD4+ T cell.

김동주 전북대학교 일반대학원 2014 국내박사

The separation and analysis of targeting cells from blood as "liquid biopsy" is available to diagnosis the various disease and continuously monitor the development of disease. Various techniques are already developed for targeting cell separation, but remains technically challenging, such as capture efficiency and purity. Recently, varied research groups are studying on the nanostructure based cell separation with high capture efficiency, which is not require any facility for cell capturing. Because, the nanostructured substrates has intensively high contact area between targeting cell and probe by large surface area. However, for rare cell separation in blood, the capture efficiency and purity of nanostructured substrate must be improved by analysis the interaction between nanostructure and targeting cell. Thus, in this dissertation, we will present our works on the targeting cell separation using various nanostructures, and the optimization of targeting cell searation using highly controlled nanostructures. The objective of this dissertation is to optimize the targeting cell separation by analyzing the cell behavior on various nanostructures. To achieve this goal, we have fabricated the various nanostructures, and immobilized the streptavidin on nanostructure surface. Additionally, we estimated the capture efficiency, and analyzed the cell behavior on nanostructure by SEM. The organization of this disseration is as follow. In chapter 1, we briefly introduced the disease diagnosis (i.e., AIDS, cancer, and Alzheimer's disease) by targeting cell separation as liquid biopsy, and the isolation and detection method with four different technologies such as immunomagnetic, size based filtration, microfluidic channel, and nanostructure. Furthermore, we summarized the advantages and disadvantages of each technique. In chapter 2, we discussed the separation of CD4+ T lymphocytes from mouse splenocytes using SiNW and QNP. The capture efficiency of each substrate was calculated using flow cytometry, and analyzed the captured CD4+ T lymphocytes on nanostructure using SEM. Additionally, we also developed the counting isolated cells with a photolithographically patterned grid structure on the STR-functionalized-QNP (STR-QNP) arrays on one chip. In chapter 3, we discussed the nanowire substrate-based laser scanning cytometery (LSC) for quatitation of circulating tumor cells (CTC) with cell population in the range of 5-3,000 cells. First, we discussed the quantitation of captured CTC on QNP and patterned SiNW using LSC, and automatically analyzed the quantitation of captured CTC. And then, we demonstrated the adhesion, spreading and mirgration of A549 on nanostructured substrate after 48 hours cultivation. In chapter 4, we discussed the filopodial morphology correlates to the capture efficiency of CD4+ T lymphocytes on nanohole array (NHA) and quartz nanopillar (QNP). To optimize the capture efficiency of QNH and QNP, we developed the highly controlled nanostructure (i.e., diameter, height, and distance). And then, we conducted the optimization of capture efficiency of CD4+ T lymphocyte, and demonstrated the filopodial morphology on shape modulated NHA and QNP. Additionally, we calcultated the cell traction force (CTF) on QNP using FIB assisted technique. In the final chapter (chapter 5), we summarized the results of this dissertation.

노만 빈센트 필의 自己啓發論 중 冥想的 要素

김동주 원광대학교 동양학대학원 2010 국내석사

노만 빈센트 필은 20세기 후반 미국의 저명한 목사였다. 그는 많은 저서, 특히 유명한 그의 주저 ‘적극적 사고방식’을 통해 적극적인 자기 계발적 사고방식을 주창하였다. 20세기 초반부터 서구의 인본주의 심리학은 자기 확신적 사고방식의 중요성을 강조하였는데, 일부 대중 심리학자들이 인본주의 심리학의 이와 같은 주장을 일반 대중들이 이해하기 쉽도록 개조하여 이른바 ‘Can-Do Spirit’라고 소개하였다. 1930년대의 미국 사회는 비극적인 세계대공황 여파로 수많은 사람들이 졸지에 직업을 잃고, 집 없는 사람들이 되어 길거리에서 노숙하는 사태가 벌어졌다. 성직자로서 곤궁에 처한 사람들을 위로할 필요성을 강하게 느꼈던 노만 빈센트 필은, 이를 위해 진지하고 성실하게 설교를 계속하였고, 많은 책을 저술하였다. 그는 설교와 저술을 통해 강인한 ‘Can-Do Spirit"를 가지고 이른바 세속적 성공을 거둘 것을 강조하였는데, 그의 이러한 ‘Can-Do Spirit'사상 속에 많은 명상적인 요소가 있음을 발견할 수 있다. 최근에 이르기까지 명상이란 동양에 특유한 사상이라고 여겨왔으나 서구의 기독교 사상에도 명상의 전통이 이어져 왔고, 따라서 기독교 성직자인 노만 빈센트 필의 저서 속에도 많은 명상적 요소가 포함되어 있다. 세속적인 성공을 위해 그는 매일 매일의 기도, 예배, 침묵, 자기암시, 심상화, 자율훈련, 숙고, 영적인 체험, 그리고 심지어는 정신의학적인 심리치료를 이용할 것을 되풀이 강조하였는데, 이 모든 것들이 아주 좋은 명상 방법들이다. 명상적 생활을 위해서는 세속으로부터 떠나야 한다고 여기는 이들이 많으나, 세속에서도 명상적 생활을 영위할 수 있고, 명상을 통해서도 세속의 성공을 이룰 수 있다고 생각한다. 따라서 우리는 노만 빈센트 필의 사상, 그리고 세속에서의 성공을 위해 그가 강조했던 여러 방법들에서 많은, 그리고 아주 효과적인 명상적 요소가 갖춰져 있음을 알 수 있다. Norman Vincent Peale was a prominent church minister at late 20th century in USA. Through his many books, especially his famous book titled "The Power of Positive Thinking", he had been advocating positive self-development thinking. From early 20th century, humanistic psychology claimed the important of confident thinking. Some popular psychologists adjusted the humanistic psychology's said thought to easy understanding for the general public and then proposed so called 'Can-Do Spirit'. At nineteen thirties, American society had experienced tragic economic crash, and there were so many jobless and homeless people on the streets. As a minister, Norman V. Peale felt to need solacing people, so he preached earnestly and wrote many books for this purpose. He claimed to achieve secular success through his books and sermons, but among his thoughts for secular success through 'Strong Can-Do Spirit', we can find many meditative factors. Up to now, they have been considering meditative thoughts are peculiar for Oriental society, but there are some meditative tradition in Christian thoughts and there are many meditative factors in Norman V. Peale's thoughts, too. For achieving secular success, he strongly suggested that Everyday Prayer, Divine Service, Silence, Self-suggestion, Imagination, Autogenic training, thinking, Spiritual or mystical Experiencing and even Psychological therapy. All of them are good meditative methods. They think that meditative life must be secluded from the world, but we insist secular life can be meditative life, even for achieving secular success. So Norman V. Peale's thoughts or methods for secular success have many and good factors of meditation.

김동주 세명대학교 2020 국내박사

인삼(Panax ginseng, C.A Meyer)은 원산지가 한반도와 만주로 되어 있고, 학명은 러시아 식물학자 C. A. Meyer가 1843년 세계 식물학회에 보고하면서 명명되었다. 고려인삼은 역사적으로 우리나라의 농산물을 대표하는 브랜드로 성장해 왔으며 매우 소중한 우리 민족의 유산이다. 제1장에서는 우리나라 인삼 산업의 역사적 배경과 연구 방법 및 범위 그리고 본 논문을 준비하기 위한 선행 연구 등에 대하여 기술하였다. 제2장에서는 우리나라 인삼 산업이 처한 현실 인식 및 당면 과제들을 찾아내고 그 대안을 찾기 위한 방법으로 가치사슬(Value Chain) 이론을 선택한 이유와 이론에 대한 간략한 소개 및 유용성에 대하여 기술하였다. 제3장부터는 우리나라 인삼 산업에 대한 구체적인 자료를 기준으로 서술하면서 인삼 산업의 가치사슬을 형성하는 단계별로 문제를 인식하는 데에 주력하여 기술하였다. 제4장에서는 농가 인삼 경작 현황 및 농가 실태에 대한 설문 조사를 통하여 원료삼 생산단계에서의 통계적 분석 결과를 제시하였으며, 인삼 가공 단계에서는 우리나라의 대표적인 2개 인삼주식회사 및 11개 인삼농협조합에 대한 경영 실태 분석을 통하여 인삼기업의 부가가치 증대시키는데 어떤 문제점들이 있는지에 대하여 서술하였다. 제5장에서는 각 가치 사슬(Value Chain) 단계별로 인삼 산업의 부가가치 제고 방안을 제안하였다. 원료삼 생산단계의 부가가치 제고 방안으로는 친환경 인증(유기농과 무농약인증)과 GAP 인증, PLS 도입, 생산 이력 추적 관리제도 및 시범사례로 인삼수매 전용박스 개발, 소포장 세척 수삼과 생산이력 추적 QR 코드 부착 등의 사례를 제안하였다. 인삼 가공단계에서는 인삼 제품류 품질규격 개선, 인삼 전통식품 규격, 인삼의 국내 의약품 규격, 인삼의 국외 의약품 규격 등에 대한 내용과 인삼류 국가 품질인증 제도의 도입 방안을 구체적으로 검토하고 제안하였다. 그리고 13개 주요 인삼 가공 기업의 경영 현황을 비교 분석하여 인삼산업의 부가가치를 제고하고 경쟁력을 강화할 수 있는 6가지 방안을 제안하였다. 소비 단계에서는 인삼 소비자들이 인삼에 대한 올바른 인식을 바탕으로 구매 의사결정을 할 수 있도록 설문 조사 분석 결과를 제시하고, 인삼산업의 유통 구조를 개선하는 방안을 제안하였다. 제6장에서는 연구 결과에 대한 요약 및 결론을 기술하였다. 생산 단계에서의 결론은 첫째, 안전한 인삼을 생산하여야 한다. 둘째, 안전한 인삼에 대해 소비자가 확인하고 신뢰할 수 있는 시스템을 구축하여야 한다. 셋째, 안정적인 계약재배를 통하여 수익이 증대될 수 있도록 해야 한다. 가공단계에서의 결론은 인삼 시장의 구조개혁에 대한 것으로 영세한 11개 조합 기업을 1개의 기업으로 통폐합하는 것으로 내릴 수 있다. 한국 인삼 산업이 위기에서 벗어나 새로운 성장 모멘텀을 확보하고 고려 인삼이 세계적인 브랜드로 그 위상을 더욱 공고히 하기 위해서는 각 가치사슬 단계별로 부가가치를 제고하고 인삼 기업의 구조 개혁 및 경영 혁신을 통하여 근본 경쟁력을 강화하는 것이 현재 우리나라 인삼 업계가 가장 시급하게 추진해야 할 과제라고 본다. Ginseng (Panax ginseng, C.A Meyer) is native to the Korean Peninsula and Manchuria, and the scientific name was named when Russian botanist C. A. Meyer reported to the World Botanical Society in 1843. Looking at the etymology of Panax, the generic name of ginseng, Pan means 'everything' and Axos means 'medicine', which means 'panacea'. Panax ginseng has historically grown as a brand that represents Korea's agricultural products and is a very valuable heritage of Korea. However, the trend of Korean ginseng industry over the past 30 years is not optimistic, despite the efforts of ginseng workers and the active support of the government and local governments. In the first chapter of this paper, we describe the historical background, research method and scope of Korean ginseng industry, and previous studies to prepare this paper. In Chapter 2, 'Value Chain Theory' was selected as a way to find out the realities and challenges of the Korean ginseng industry and find alternatives. A brief introduction to the theory and its usefulness are described. Chapter 3 describes specific data on the Korean ginseng industry and focused on recognizing the problems in each step of forming 'value chain' in each step of the ginseng industry. The main contents of this chapter are the production and export status of raw ginseng, the status of ginseng cultivation farmers, sales status and price of ginseng products and product types. Chapter 4 describes the statistical analysis of farming ginseng cultivation status and farm conditions for production analysis of raw ginseng. Next, we investigated the fundamental problems in increasing the value added of ginseng companies by analyzing the management status of two representative ginseng corporations and 11 ginseng cooperatives in Korea. It also describes where those problems come from and what are the countermeasures. In the ginseng consumption stage, surveys on consumer decision making and demographic surveys were conducted. Chapter 5 describes how to increase ginseng value at each stage of each value chain. In the production stage of raw ginseng, eco-friendly certification, GAP certification, and PLS introduction and settlement were proposed to increase consumer confidence in quality in order to create added value through safe ginseng production. In the ginseng processing stage, current problems and alternatives were specifically proposed for the improvement of the quality standards of ginseng products, the introduction of the national quality certification system for ginseng products, and the introduction and development of high value-added ginseng products. In addition, it proposed a method of improving the value added of major ginseng processing companies and improving the distribution structure of the ginseng industry. Ginseng consumption promotion activities should be strengthened at the consumption stage to provide information for proper recognition of ginseng. Chapter 6 summarizes the results of the study by dividing it into production stage, processing stage and consumption stage. In the production stage, a safe ginseng should be produced and a system for consumers to do this must be established. In addition, stable contract cultivation should increase profits. In the processing stage, it is proposed to merge 11 small union companies into one union. The fundamental solution of the ginseng industry is to build an effective competition market structure by realizing "The economy of scale". The case of integration of Danish slaughterhouses and unions cited in Chapter 2 suggests that the Korean ginseng cooperatives should be considered at this point.

김동주 충북대학교 대학원 2013 국내석사

무선 멀티미디어 센서 네트워크는 무선 통신과 비정형 네트워크 토폴로지를 기반으로 운용되며 스트리밍 미디어 데이터가 연속적으로 전송되므로 악의적인 목적을 가진 사용자의 공격에 쉽게 노출이 된다. 따라서 무선 멀티미디어 센서 네트워크에서의 보안은 필수적이다. 대용량 데이터를 모두 암호화 하는 것은 한정적인 자원을 가지고 있는 무선 센서 네트워크에서는 적합하지 않으므로 데이터의 일부만을 암호화 하는 선택적 암호화 기법에 대한 연구가 활발히 진행되고 있다. 본 논문에서는 프레임 간의 동적인 움직임을 감지하고 이를 압축하고 암호화하는 선택적 암호화 기법을 제안한다. 동적인 영역만의 암호화를 통해 암호화 대상 데이터의 크기를 효과적으로 감소시킴으로써 스트리밍 데이터에 적합하며 전체적인 네트워크 수명을 연장시키는 것이 가능하다. 제안하는 기법의 우수성을 보이기 위해 기존 기법과 제안하는 기법의 성능 평가를 수행한다. 성능평가 결과, 제안하는 기법은 기존 기법에 비해 데이터 전송량이 약 80.3% 감소했으며, 영상을 전송하기 위한 에너지 소모는 약 76.9% 감소하였다.
