임정아,권순욱,Lim, Jung-A,Kwon, Soon-Wook 한국건설관리학회 2011 한국건설관리학회 논문집 Vol.12 No.4

In the construction industry, there is a growing demand for new programs incorporating IT applications. In construction, initiatives calling for changes ensuring the improvement of productivity, quality and safety, and for the strengthening of global competitiveness, have contributed to the increased need for exploring new markets. Moreover, the government's supportive policies have helped develop profit models. Meanwhile, the industry and the government have supported the efforts for identifying and disseminating successful case studies - as part of the strategy for evaluating and promoting the developed programs. However, the criteria for identifying/evaluating successful cases remain vague, and the viewpoints of participants differ depending on their disciplines. These discrepancies could lead to inconsistent results. Thus, it is imperative that a criterion be provided, upon which to judge the success or failure of implementation cases and to disseminate role models. It is also imperative that a direction of improvement be proposed. This study was conducted to propose the criteria for and process of evaluating the success of construction-IT convergence to help promote the construction industry incorporating IT applications. To that end, success factors for and the significance of IT-incorporated construction were identified. 현재 건설업 및 산업전반에서 IT기술을 융합한 새로운 사업에 대한 수요가 증가하고 있다. 건설 생산성, 품질, 안전향상을 위한 변화와 국제 경쟁력 강화를 위해 신시장 개척의 필요성이 증대되었으며 정부의 정책적 지원을 통해 u-city와 같은 수익모델이 개발되고 있다. 이와 함께 개발된 사업을 평가하고 활성화하기 위한 전략으로 산업계 및 정부차원에서 성공사례 발굴과 보급에 대한 지원이 이뤄지고 있다. 하지만 성공사례를 판단하기 위한 평가기준이 모호하고 각 분야의 참여자들의 관점이 달라서 판단주체가 누구냐에 따라 결과가 다르게 도출될 수 있어, 어떤 기준으로 성공사례를 판단하고 성공모델로 보급할 지에 대한 기준을 마련하여 발전방향을 제시할 필요가 있다. 따라서 본 연구에서는 건설 IT 융합 산업의 활성화를 위해 건설 IT융합 사업의 성공요인과 그 중요도를 도출하여 건설 IT융합 성공사례의 평가기준을 제시하는 것을 목적으로 한다.

Background and Purpose : Though there were many clinical studies of acupuncture effects they didn't have appropriate control group. So we didn't say it was true acupuncture effect, though subjects in clinical study improved. To investigate the possibility of sham acupuncture application, we examined how well subjects distinguished real acupuncture from sham acupuncture. Methods : We investigate the possibility of sham acupuncture application as the following 3 kinds of methods. 1. The public (n=60) and Oriental Medicine Doctors (n=20) looked at the appearance of acupuncture and then were treated with randomly allocated acupuncture and judged it as real or sham. 2. The public (n=60) and Oriental Medicine doctors (n=20) were treated with randomly allocated acupuncture, then they looked at the appearance of acupuncture and judged it as real or sham. 3. The public (n=60) were treated with randomly allocated acupuncture (right-real-left-sham), (right-sham-left-real), (left-real-right-sham), (left-sham-right-real), then they judged it as real or sham. Results : 1. When the public (n=60) looked at the acupuncture appearance, the correct judgement ratio was 63.3%. After they were treated with acupuncture, the correct judgement ratio was 50.0%. 2. When Oriental Medicine doctors (n=20) looked at the acupuncture appearance, the correct judgement ratio was 25.0%. After they were treated with acupuncture, the correct judgement ratio was 45.0%. 3. When the public (n=60) were treated with acupuncture, the correct judgement ratio was 50.0%. After they looked at the acupuncture appearance, the correct judgement ratio was 63.3%. 4. When Oriental Medicine doctors (n=20) were treated with acupuncture, the correct judgement ratio was 65.5%. After they looked at the acupuncture appearance, the correct judgement ratio was 65.0%. 5. After the public (n=60) were treated with randomly allocated sham or real acupuncture as (right-real-left-sham), (right-sham-left-real), (left-real-right-sham), or (left-sham-right-real). the correct judgement ratio was 66.7% in looking at the acupuncture appearance group, and in not looking at 60.0%. Conclusion : These results indicated that Kim Sham Acupuncture could apply to the double blind clinical study of acupuncture effect. And more continuous studies are needed on Sham Acupuncture apparatus.

기상청 지진관측소 관측환경별 표준 배경잡음 모델 개발

임정아(Jung-A Lim),윤원영(Won-Young Yun),서동일(Dong-Il Seo) 대한지질학회 2021 대한지질학회 학술대회 Vol.2021 No.10

기상청은 지진관측을 위해 광대역, 단주기, 가속도 및 공중음파 등 다양한 종류의 지진계로 구성된 전국 268개소의 지진관측소를 운영하고 있다. 지진계는 시추형과 지표형으로 구분되며, 설치된 장소는 내륙, 해안, 섬 등 다양하다. 지진계에는 일반적으로 지진에 의한 진동 외에도 인간의 활동, 바람, 파도 등 여러 요인에 의한 배경잡음도 함께 기록된다. 이러한 잡음들은 지진 감시에 방해 요소로 작용함에 따라 제거하는 노력이 필요하며, 개별 관측소에 대한 배경잡음수준 평가는 지진자료를 수집하는 관측환경의 안정성을 평가하는 지표로 활용되고 있다. 기상청은 지진관측환경의 객관적인 평가를 위해 2009년과 2016년 두 차례에 걸쳐 기상청 단일 표준 배경 잡음 모델을 개발하였다. 2016년 개발된 표준 배경잡음 모델은 기상청 속도계 지진관측소 68개소를 이용한 단일모델로 현재까지 배경잡음수준 평가에 활용하고 있다. 2021년 현재 기상청에서는 확대된 관측소 및 다양한 지역과 설치환경 등을 반영한 보다 세분화된 표준 배경잡음 모델이 필요하다. 배경잡음은 주변 환경과 부지 특성에 따라서 주파수 별 특성이 다르기 때문에 본 연구에서는 관측환경에 따른 세분화된 기상청 표준 배경잡음 모델을 제시하고자 한다. 본연구에서는 기상청 지진관측소에 기록된 2020년 1년간의 초당 100샘플 자료를 활용하였으며, 배경잡음 분석을 위해 PQLX (PASSCAL Quick Look eXtended) 프로그램을 이용하여 주파수별 잡음수준(dB)를 계산하였다. 또한 표준정규분포 및 신뢰범위(μ+2σ) 등의 확률론적 방법을 적용하여 표준 배경잡음 모델을 작성하는데 방해되는 이상자료를 제거하고 순수잡음을 추출하였다. 기상청 관측소 268개소의 지진관측자료에 대하여 기존 2016년도 단일 표준 배경잡음 모델과 본 연구의 신규 개발된 표준 배경잡음 모델을 적용하여 배경잡음수준 이탈률을 비교한 결과, 해안이나 지표와 같은 비교적 잡음의 영향이 많은 관측환경의 경우 세분화된 모델을 적용하였을 때 크게 감소하는 것을 확인 할 수 있었다. 또한, 내륙보다는 해안에서, 시추공보다 지표에서 좀 더 높은 배경잡음 수준을 보였다. 따라서 관측환경별 세분화된 표준 배경잡음 모델을 활용하여 실시간으로 수집되는 기상청 지진관측자료의 이상파형 및 관측환경의 변화를 신속하게 파악하고 품질관리에 활용할 수 있을 것으로 기대된다.

Objectives: We have studied the effects of GaAlAs (808 nm) low level laser therapy (LLLT) and acupuncture at BL40 on neuropathic pain in rats induced by lumbar spinal nerve 5 ligation. Methods: To produce the model of neuropathic pain, under isoflurane 2.5% anesthesia, the lumbar spinal nerve 5 was ligated by 6-0 silk thread. After neuropathic surgery, we examined if the animals exhibited the behavioral sign of allodynia. The allodynia was assessed by stimulating the medial malleolus with von Frey filament and acetone. Three weeks after the neuropathic surgery, GaAlAs (808 nm) low level laser and acupuncture was inserted at BL40 once a day for 6 days. We examined the withdrawal response of neuropathic rats` legs by von Frey filament and acetone stimulation. And also the author examined c-Fos, nociceptin and nociceptin receptor in the midbrain central gray of neuropathic rats. Results: The GaAlAs (808 nm) low level laser therapy and acupuncture at BL40 decreased the withdrawal response of mechanical allodynia that assessed with von Frey filament in LLLT group on 5 and 6 times and with acetone in AT group and LLLT on 6times. The LLLT and acupuncture at BL40 decreased the c-Fos protein expression in AT and LLLT groups. The 808 nm LLLT and acupuncture at BL40 decreased the nociceptin protein and nociceptin receptor protein in LLLT group. Conclusions: We have noticed that GaAlAs (808 nm) LLLT and acupuncture at BL40 decreased mechanical allodynia in the model of neuropathic pain. c-Fos, nociceptin and nociceptin receptor expression in the central gray of that group was also decreased. This study can be used as a basic resource on a study and a treatment of pain.

OLED 내구성에 미치는 무기/에폭시층 보호막의 영향

임정아(Jung A Lim),주성후(Sung Hoo Ju),양재웅(Jae Woong Yang) 한국표면공학회 2009 한국표면공학회지 Vol.42 No.6

The passivation films with epoxy layer on LiF, SiNx and LiF/SiNx inorganic layer were fabricated on OLED to protect device from the direct damage of O₂ and H₂O and to apply for a buffer layer between OLED device and passivation multi-layer with organic/inorganic hybrid structure as to diminish the thermal stress and expansion. Red OLED doped with 1 vol.% Rubrene in Alq₃ was used as a basic device. The device structure was multi-layer of ITO(150 ㎚) / ELM200_HIL(50 ㎚) / ELM002_HTL(30 ㎚) / Alq₃: 1 vol.% Rubrene(30 ㎚) / Alq₃(30 ㎚) / LiF(0.7 ㎚) / Al(100 ㎚). LiF/epoxy applied as a protective layer didn't contribute to the improvement of life time. While in case of SiNx/epoxy, damage was done in the passivation process because of difference in heat expansion between films which could occur during the formation of epoxy film. Using LiF/SiNx/epoxy improved lifetime significantly without suffering damage in the process of forming films, therefore, the best structure of passivation film with inorganic/epoxy layers was LiF/SiNx/E1.

Objective : The purpose of this study is to investigate nucleotide sequence and extract cytotoxicity of Scolopendrae corpus. The nature and taste of Scolopendrae corpus is hot, Warm and toxic, and the effect of this is dispelling wind, anti-spasmodic action and detoxication so it has been used for C.V.A, facial palsy, sensory disorder at extremities, wounds and arthritis. Methods : Scolopendrae corpus were collected by locality on the market. They were morphologically classified. Their nucleotide sequence was investigated and compared among them. In addition, the water-alcohol extract cytotoxicity of them was studied by MTT-based cytotoxicity assay. Results : It was shown that the each Scolopendrae corpus by locality is almost identical at genetic result and is identified as Scolopendra subspinipes mutilans L. Koch. Nucleotide sequence of Scolopendra subspinipes mutilans L. Koch in this study will help to discriminate other species of Scolopendrae corpus. The water-alcohol extract of Scolopendra subspinipes mutilans L. Koch did not induce cytotoxicity on Hep G2, L929 cell and peritoneal macrophages. Besides, it did not influence nitrite production of peritoneal macrophages. These results can be used as basic data for genetic discrimination with another species of scolopendrae corpus.

중국 만주지역 S파 상대주시 토모그래피

김용우,김효지,임정아,장성준,Kim, Yong-Woo,Kim, Hyo-Ji,Lim, Jung-A,Chang, Sung-Joon 한국지구물리물리탐사학회 2018 지구물리와 물리탐사 Vol.21 No.1

중국 만주지역은 백두산이라는 거대한 화산이 존재하는 지질학적, 지구물리학적으로 중요한 곳이다. 백두산은 전 세계에서 규모가 가장 큰 화산 중 하나이며, 최근 분화 조짐이 보이면서 사람들의 관심이 집중되어 있다. 본 연구는 중국 만주지역의 하부 깊이 약 100 ~ 600 km 사이의 속도구조를 파악하기 위해 S파 상대주시 토모그래피를 수행하였다. 연구에는 IRIS (Incorporated Research Institutions for Seismology)에서 제공하는 Necess Array (North East China Extended SeiSmic Array)에 기록된 2009 ~ 2011년 기간 동안 진앙거리 $30^{\circ}$ 이상 $90^{\circ}$ 미만의 지진 자료를 사용하였다. 획득한 자료들에 다중채널 상호상관법(multi-channel cross-correlation method)을 적용함으로써 상대주시를 계산하였다. 그 결과 중국 만주 지역에 분포하는 화산지대와 토모그래피 이미지에서 나타나는 저속도 이상체의 위치가 동일함을 관측하였다. 백두산 하부 100 ~ 600 km 사이에 저속도 이상이 발견되었으며 이 저속도 이상체는 백두산의 마그마 공급과 연관이 있을 것으로 판단된다. 서쪽에 다통 화산지대 동쪽 하부 300 km 부근까지, 북쪽에 우달리안치 화산지대의 경우 하부 200 km 부근 까지 저속도 이상이 발견되었다. 이 저속도 이상체는 백두산의 형성과 생성원인이 다르며, 다통 화산지대 동쪽 저속도 이상의 경우 깊은 맨틀에서의 상승류에 의해 생성되었을 가능성이 있으며, 우달리안치 화산의 경우 연약권에 상승류에 의해 생성된 것으로 판단된다. The Northeast China is an important site geologically and geophysically because of a huge volcano called Mt. Baekdu, which is one of the largest volcanoes in the world. Signs of eruption have been recently observed and people are keen to its behavior. We carried out relative travel time tomography to investigate the velocity structure between 100 ~ 600 km depth beneath Northeast China. We used teleseismic data during 2009 ~ 2011 recorded in NecessArray provided by IRIS (Incorporated Research Institute for Seismology). The relative observations were obtained by using the multi-channel cross-correlation method. Based on the tomographic results, we observed that the locations beneath which low-velocity zones are observed coincide with the locations of several volcanic regions in Northeast China. A low-velocity anomaly is revealed beneath Mt. Baekdu down to 600 km depth, which is thought to the main origin of the magma supply for Mt. Baekdu. Another low velocity anomaly is observed beneath east of the Datong volcano down to around 300 km depth, which is inferred to be related to an upwelling from deep mantle. We observed a low velocity anomaly beneath the Wudalianchi volcano down to around 200 km depth, which may imply that this volcano has been formed by an upwelling from the asthenosphere.
