임성원,최선규 한국경영과학회 2000 한국경영과학회 학술대회논문집 Vol.- No.1

정보통신기술을 바탕으로 한 산업은 산업화시대의 기간산업에 비해 지식 및 기술집약적 산업으로서 기업 및 산업의 경쟁력의 원천은 바로 지속적인 연구개발을 통한 새로운 아이디어와 기술의 창출에 있다고 할 수 있다. 정부에서도 정보통신 분야에서의 연구개발 투자에 대한 중요성을 인식하고 지속적으로 연구개발에 대한 투자를 확대해 왔다. 그러나 정보통신연구개발 투자의 지속적인 증가에도 불구하고 관리적 측면에서는 아직까지 효율적인 관리가 확립되지 못하고 있는 실정이다. 따라서 본 연구에서는 먼저 현행 정보통신연구개발 관리가 어떻게 수행되고 있는 지를 과제선정과정과 선정 후 관리과정으로 구분하여 각각에 대한 현황조사를 통해 그 실태를 파악한다. 그리고 그러한 실태분석을 통하여 현행 연구개발 관리체제가 안고 있는 문제점을 지적해보고, 마지막으로 문제점들을 극복할 수 있는 정보통신 연구개발의 효율적 관리체계를 확립하기 위한 개선방향을 모색하고자 한다.

Optimized design of silicone pad for bended window lamination in organic light-emitting diodes

임성원,장동훈,박병민,한관영 대한기계학회 2019 JOURNAL OF MECHANICAL SCIENCE AND TECHNOLOGY Vol.33 No.12

Recently, various types of displays have been developed for use in smartphones. In particular, the shape of the glass used as the cover window of a smartphone has developed from a flat shape to a vandal shape with multiple curvatures. The lamination process for bonding an OLED backplane to such a bended cover window requires a relatively high level of skill. To develop such a technique, we designed a silicone pad with sufficient adhesive strength to suit the various curvatures. In this paper, we have confirmed the results.

『Short-course Chinese Character Text』 is the Textbook, of Chinese Character and Chinese Writing for children which was published at Patriotic Illumination Period. Patriotic Illumination Period is the period to get to meet the new turn by the introduction of modern Educational system the change of curriculum and the dispute of language and Chinese Writing from the viewpoint of Characteristic of history of Chinese Writing Education. 『Short-course Chinese Character Text』 shows the special form in composition method and contents out of the Chinese Writing textbooks to be made at the Period also. Composition methods are as follows; First, it is the book centering around Chinese character study, but it takes the organic composition methods, so that one may study by linking to Chinese character, Chinese language and Chinese writing. Second, it is receiving the merits of he classification methods by kinds and the compounding methods of set phrase of Chinese character which are the traditional composition methods of teaching material of Chinese writing with the characteristic of development. In the contents, the substantial knowledge to be necessary for daily life which gets out of the contents centering around former Confusion doctrine and the recognition of period actuality to inspire ethical consciousness which have been emphasized traditionally etc. are diverse. Thus, it is showing the character of populace illumination through Chinese writing study well. The educational meaning that the composition method and contents out of 『Short-course Chinese Character Text』 have may be found in that it considered the intellectual ability of learners by fitting to changing actuality. And especially, the elaborateness that composition method and shows has many merits to be able to refer for making Chinese Writing textbook in the future. 『Short-course Chinese Character Text』 is helpful to presenting the desirable direction that Chinese Writing education should advance at the actuality of nowadays that the policy of language and literature about Korean language and Chinese writing changes at all times still and that the dispute from the maintenance or abolition of Chinese writing curriculum to direction, contents and revenue index etc. doesn't cease whenever the curriculum is revised because of this.

Current status of immune checkpoint inhibitors in treatment of non-small cell lung cancer

임성원,안명주 대한내과학회 2019 The Korean Journal of Internal Medicine Vol.34 No.1

Lung cancer remains a leading cause of cancer mortality worldwide, including in Korea. Systemic therapy including platinum-based chemotherapy and targeted therapy should be provided to patients with stage IV non-small cell lung cancer (NSCLC). Applications of targeted therapy, such as an epidermal growth factor receptor (EGFR) tyrosine kinase inhibitors (TKIs) and anaplastic lymphoma kinase (ALK) inhibitors, in patients with NSCLC and an EGFR mutation or ALK gene rearrangement has enabled dramatic improvements in efficacy and tolerability. Despite advances in research and a better understanding of the molecular pathways of NSCLC, few effective therapeutic options are available for most patients with NSCLC without druggable targets, especially for patients with squamous cell NSCLC. Immune checkpoint inhibitors such as anti-cytotoxic T lymphocyte antigen- 4 or anti-programmed death-1 (PD-1) or programmed death-ligand 1 (PD-L1) have demonstrated durable response rates across a broad range of solid tumors, including NSCLC, which has revolutionized the treatment of solid tumors. Here, we review the current status and future approaches of immune checkpoint inhibitors that are being investigated for NSCLC with a focus on pembrolizumab, nivolumab, atezolizumab, durvalumab, and ipilimumab.

메탄 배출 저감을 위한 설탕을 이용한 돈 슬러리의 산성화

임성원,오세은,홍두기,김동훈 유기성자원학회 2019 유기물자원화 Vol.27 No.3

The major problem encountered during the storage of pig slurry (PS) is the release of huge amounts of greenhouse gases (GHGs), which are dominated by methane (CH4). To reduce this, concentrated sulfuric acid has been used as an additive to control the pH of pig slurry to 5.0-6.0. However, other low-risk substitutes have been developed due to some limitations to its use, such as corrosiveness, and hazards to animal and human health. In this study, sugar addition was proposed as an eco-friendly approach for limiting CH4 emission from PS during storage. The pH of PS has been reduced from 7.1±0.1 (control) to 5.8±0.1, 4.6±0.1, 4.4±0.1, 4.1±0.1, and 4.0±0.1, by the addition of 10, 20, 30, 40, and 50 g sugar/L, respectively. Lactate, acetate, and propionate were detected as the dominant organic acids and at sugar concentration above 20 g/L, lactate concentration represented 42-72% (COD basis) of total organic acids. For 40 d of storage, 20.6±2.3 kg CO2 eq./ton PS was emitted in the control. Such emission, however, was found to be reduced to 8.7±0.4 and 0.4±0.1 kg CO2 eq./ton PS at 10 and 20 g/L, respectively. Small amount of CH4 from PS at 10 g/L was emitted until 30 d of storage, while for rest of storage period, it has increased to 8.7±0.4 kg CO2 eq. t on PS ( 40% of the control) when methanogens have recovered by increasing pH to 7.0. By the end of storage, VS and COD removal in the control reached 24% and 27%, while their ranges reached 15-4% and 12-17% in the sugar added experiments, respectively. It was found that more than 90% of COD removal was done by aerobic biological process. 슬러리(Pig slurry, PS)가 저장되는 동안 상당량의 온실가스가 배출되고 있으며 메탄(CH4)이 주요 온실가스로알려져 있다. 메탄 배출을 줄이기 위해서 진한 황산을 이용하여 돈 슬러리의 pH를 5.0-6.0까지 낮춰서 저장하는방법이 사용되고 있다. 하지만 부식성이 있고, 사람과 동물에 위험하다는 단점이 있어 사용에 한계가 있다. 본 연구에서는 돈 슬러리가 저장되는 동안 배출하는 메탄을 줄이기 위해 친환경적 방법인 설탕 첨가를 시험해보고자 한다. 설탕을 이용한 돈 슬러리의 산성화 이후, 돈 슬러리의 pH는 7.1에서 설탕의 첨가량(10, 20, 30, 40, 50 g/L)에 따라5.8±0.1, 4.6±0.1, 4.4±0.1, 4.1±0.1, 4.0±0.1으로 감소하였다. 주요 유기산으로는 lactate, acetate, propionate가 검출되었으며20 g/L 이상의 농도에서는 lactate의 비중이 전체 유기산의 42-72%(COD 기준)까지 증가하였다. 대조군을 41일 동안 저장하는 동안 20.6±2.3 kg CO2 eq./ton PS가 배출되었으며 10, 20 g/L에서만 메탄이 검출되었다. 특히, 10 g/L에서는30일 이전까지는 소량의 메탄이 배출되었으나 그 이후부터는 메탄 배출량이 증가하여 8.7±0.4 kg CO2 eq./ton PS(대조군의 40%)까지 도달하였다. 이러한 현상의 원인은 돈 슬러리의 pH 상승(pH 7.0)으로 인한 메탄생성균의 활성도회복으로 판단된다. 저장 후 돈 슬러리 내 유기물 제거율은 VS 24%, COD 27%로 나타났지만 산성화를 할 경우유기물 손실(VS 15-4%, COD 12-17%)을 크게 낮출 수 있음 보였으며 저장하는 동안 감소한 COD의 90% 이상이호기 분해에 의해 일어난 것으로 보인다.

HEVC에서의 적응적 움직임 벡터 해상도를 이용한 움직임 추정 및 부호화 기법

임성원,이주옥,문주희,Lim, Sung-Won,Lee, Ju Ock,Moon, Joo-Hee 한국방송∙미디어공학회 2012 방송공학회논문지 Vol.17 No.6

본 논문에서는, 인터 예측시 움직임 벡터의 해상도를 나타내는 1비트 플래그를 두어 적응적으로 1/4 해상도의 움직임 벡터와 1/8 해상도의 움직임 벡터를 선택하고 부호화하는 방법을 제안한다. 현재 HEVC에서는 1/4 해상도의 움직임 벡터만을 이용하여 부호화하는데, 영상 신호의 변화가 복잡한 영역에서 1/4 해상도의 움직임 벡터만으로는 충분한 효율을 얻어내지 못한다. 따라서 본 논문에서는 PU마다 해상도 플래그를 1비트 추가하여 적응적으로 움직임 벡터의 해상도를 결정할 수 있도록 한다. 제안한 방법의 실험 결과로서, 인코더의 복잡도는 30%~33% 증가하고 디코더의 복잡도는 1%~5% 증가하였지만, 휘도신호의 압축효율은 최대 5.3% 좋아졌으며, 색차신호의 압축효율은 최대 7.9% 좋아졌다. In this papar, we propose a new motion estimation and coding technique using adaptive motion vector resolution. Currently, HEVC encodes a video using 1/4 motion vector resolution. If there are high texture regions in a picture, HEVC can't get a performance enough. So, we insert additional 1-bit flag meaning whether motion vector resolution is 1/4 or 1/8 in PU syntax. Therefore, decoder can recognize the transmitted motion vector resolution. Experimental results show that maximum coding efficiency gain of the proposed method is up to 5.3% in luminance and 7.9% in chrominance. Average computional time complexity is increased about 33% in encoder and up to 5% in decoder.
