박철수,Park Cheol-Soo 한국주거학회 2006 한국주거학회 논문집 Vol.17 No.2

The exploration of the spatial structure of a particular urban area, or the analysis of the tendencies of spatial consumption among urbanites, can be a literary-geographical attitude, shifting literary interests toward geography. It may also constitute a field of cultural geography that reads texts as cultural symbols. Based on this kind of attitude, the paper reads the literature of Park Wan So, particularly the popular novels that involve urban and residential spaces of Seoul, as a cultural text that carries a kind of symbolism. It proceeds with the idea that most popular novels reflect the mass phenomena of its times, and that representing real cultural experiences through text, it becomes a means of generalizing the identity shared by the anonymous masses and the characteristics of particular places. Hence the individuality of Park Wan So, who moved to Seoul during the Japanese colonial period and hence forth lived as a middle-class citizen, is inseparable from her literary work. With this attitude and methodology, the paper argues that in the urban space of metropolitan Seoul, the modern ambivalent gaze of the colonial period shifted toward increasingly new value systems, and was replaced by a dichotomous view, and furthermore, that the contents of this dichotomous view has experienced a multivalent transformation through the accumulation of time and the expansion of space.

박철수,조용진,설한신,Park, Cheol-Soo,Cho, Yong-Jin,Seol, Han-Shin 한국음향학회 2007 韓國音響學會誌 Vol.26 No.5

캐비테이션 터널에서 소음계측 실험의 주 목적은 프로펠러 소음레벨 계측과 소음원의 위치 판별이다. 한국해양연구원의 소음계측 실험용 "저소음 대형 캐비테이션 터널"의 기초연구의 일환으로 소음계측 실험이 동 연구원의 소형 캐비테이션 터널에서 수행되었다. 본 실험에서는 프로펠러 캐비테이션이 발생할 수 있는 반류조건을 만들기 위해 반류 생성용 모형체(dummy body)를 제작하였고, 유동장 내의 청음기에 의한 자체소음을 줄이기 위해 유선형으로 설계된 하이드로포일내에 청음기 배열을 설치하였다. 다양한 압력조건에서 발생한 소음장과 가상 음원의 복제음장을 계측한 후, 소음원의 위치를 추적하기 위해 주파수 비상관 Bartlett 프로세서를 적용하였다. 본 논문에서는 수행된 소음계측 시험에 대해 기술하고, 계측된 소음의 분석 및 위치추적 결과를 제시한다. The two major objectives of acoustical measurements in a cavitation tunnel are measuring the noise levels generated by rotating propellers behind a hull and localizing possible noise sources in order to reduce noise levels. Propeller noise measurement experiments were performed in MOERI cavitation tunnel at December, 2006. In order to put the propeller into cavitating conditions, a wake-generating dummy body was devised. In addition, ten hydrophones are put inside a wing-shaped casing in order to minimize the unexpected flow induced self noise around hydrophone itself. After measuring both of the noises of the rotating propeller behind the dummy body and signals generated by a virtual source, respectively the data were matched field processed using the frequency incoherent Bartlett processor to localize noises on the propeller plane. In this paper, we presented the measured noise analysis and the localization results.

박철수,Park, Cheol-Soo 한국주거학회 2008 한국주거학회 논문집 Vol.19 No.2

This study explores the beneficial methodology to increase cultural values of urban style Hanok, Korean traditional residence. Based on the literary geographical approach, this study defines the physical identities of special Bukchon Hanok area in Seoul. The explored physical identities are to provide basic fundamentals for supplying and maintaining new Hanok buildings, including how to preserve and restore the traditional Hanok areas. They are also to develop various Hanok related cultural products and to encourage Hanok popularization. In addition, this study is to add more the humane values and significances to the previous relevant researches. With these perspectives and through above mentioned methodology, the study draws the physical identities of Bukchon Hanok area and meanings as belows: The first one is the collective identity. Bukchon Hanok area is mainly composed of organic spaces with its collective scenary. Narrow alleys and curved lanes created by collective gaps between Hanok buildings, provide residents and visitors with abundant choices of moving path. The second one is the formal identity. Bukchon Hanok maintain their unique layout patterns. The basic units of Chae are combined in specific ways such as 'ㄱ', 'ㄷ', 'ㅁ' types and result typical formal expression of the area. The third one is grounding identity which represent the relationship between the earth and every-day living space. Each Chaes of house always surround Madang, Korean traditional court yard with rare vegetation. And the connection to the ground is transferred to the memories of its dwellers. Lastly, the current Hanok still preserve similar characteristics of past time Hanok such as materials, structure and styles by using unique building technics and exposing traditional ornamenting styles.

본 연구에서는 최근 꾸준한 성장세를 보이고 있는 의료산업의 국내벤처기업에 대한 신용 평가를 위해 먼저 기업의 재무 요인과 비재무 요인을 구분하여 평가지표를 개발한 다음 Saaty(1980)의 계층분석과정(Analytic Hierarchy Process; AHP)방법론을 적용하여 각 지표의 중요도(가중치)를 산출함으로써 의료벤처기업의 신용평가모형을 제시한다. 재무요인의 상위지표로는 수익성, 안전성, 활동성, 성장성, 생산성을 선택하였고, 각 상위지표에 대해서는 2개씩의 하위지표를 정하여 모두 10개의 지표를 설정하였다. 또 비재무적 요인의 상위지표로는 경영자 능력, 기술성, 시장성, 사업성, 신뢰성의 5개 영역을 정하고, 각 영역에 대해 2-5개의 하위지표를 정하여 모두 17개의 지표를 설정하였다. 신용평가지표에 대한 평가를 위해 원주의료기기클러스터 내 소재하고 있는 금융기관 및 보증기관의 심사역을 대상으로 설문조사를 한 후 이를 분석하여 평가지표에 대한 가중치를 산출하였다. This study presents the credit evaluation model for medical venture business which has been growing within the recent decade. We develop the model with two steps. At the first step, the evaluation indexes for each of the financial and non-financial factors of a firm are listed. At the second step, the weight for each index is measured by using the Analytic Hierarchy Process of Saaty(1980). The financial factors consists of 5 upper level indexes and 10 lower level indexes. The upper level indexes of the financial sector are profitability, safety, utilization, growth, and productivity. And the non-financial factors consists of 5 upper level indexes and 17 lower lever indexes. The upper level indexes in this sector are manager's competence, technical capability, marketability, business validity, and reliability. In order to get the empirical results for our model, we conduct the questionnaire survey targeting the credit assessment officers, who are practicing at the financial institutions or the credit guarantee company located within the Wonju Medical Devices Cluster.

본 논문에서는 천해 음파전달 모의에 적합한 음선기반 광대역 주파수 신호 모의기법을 제안하였다. 본 기법은 깊이에 따라 음속이 선형적으로 변하는 환경 및 층매질에서의 음선추적을 기반으로 평면파 및 구형파의 반사 및 투과, 굴절 그리고 감쇠 등을 고려해 각 고유음선의 위상 및 크기로부터 신호를 모의한다. 본 기법의 가장 큰 특징은 주파수영역을 거치지 않고 시간영역에서 이산화된 신호를 직접 모의함으로써 주파수 대역에 관계없이 계산시간을 단축할 수 있다는 것이다. 끝으로 제안된 기법을 네 가지의 테스트환경에 적용하여 기존의 검증된 모텔 (ORCA, Ram) 의 결과와 비교하여 그 효용성을 검증하였다 This paper proposes a ray-based forward modeling scheme which is suitable for the shallow water acoustic wave propagation simulations. The proposed model comprises of ray tracings for the layered media of which sound speed profiles are interpolated linearly. considerations of plane and spherical wave reflection coefficients. and calculations of the phases and the amplitudes of eigen rays. The main characteristic of the scheme is fast simulation time due to direct calculation of the broad-band time signals in the time-domain, i.e. without transformation of the frequency-domain solutions to the time si 밍 131s. Finally, we applied the model to 4-types of test environments and compared the resulting signals with those of ORCA and Ram in order to validate the proposed model.

조정연(Cho, Jeong-Yeon),박철수(Park, Cheol-Soo) 대한건축학회 2014 대한건축학회논문집 Vol.30 No.1

The aim of this paper is to verify the effectiveness of the District Unit Plan for the exclusive residential zone in Jukjon, Dongbaek, and Pangyo area which is the land development area of the national capital region. The results showed that the Plan was not effective for the architectural developments due to lack of management of the directions of the Plan and lack of pre-conditions for the implementation and the physical environment oriented regulatory approach. We describe the following further details of the results in terms of city density and street view management. Especially according to density, the physical size issue can be mainly found in floor area ratio and the number of floors. Our analysis shows that main reason for both excessive floor area ratio and the excessive number of floors is the violation of the number of households through household split. And street view issues include shape of roof, building construction line, shared public land, parking, and the most common District Unit Plan violation is parking.

박철수(Cheol-Soo Park) ․ 임청환(Cheong-Hwan Lim) ․ 정홍량(Hong-Ryang Jung) ․ 신성수(Seong-Soo Shin) 대한방사선과학회(구 대한방사선기술학회) 2008 방사선기술과학 Vol.31 No.4

현재 방사선치료는 선형가속기에 의하여 대다수 이루어지고 있으며 사용되는 방사선인 광자도 의학의 발전에 의해 고에너지화 고선량화 되고 있다. 본 연구에서는 방사선치료 조사면에서 중성자 측정이 가능한 CR-39를 이용한 중성자 검출법을 이용하였다. 선형가속기에서 발생되는 X선(광자)치료 시 발생 되는 중성자의 선량을 CR-39를 이용한 중성자 검출법을 이용하여 측정하고, 임상적 응용으로 고에너지 광자를 이용하여 암 치료에 사용할 때 중성자의 발생이 환자치료 선량과 연관되는 어떤 문제를 발생시키는지를 연구한 결과는 다음과 같다. 속중성자의 경우 광자 1 Gy 조사 시 평균 0.35 mSv, 2 Gy 조사 시 평균 0.65 mSv, 5 Gy 조사 시 평균 1.82 mSv, 열중성자의 경우 광자 1 Gy 조사 시 평균 0.26 mSv, 2 Gy 조사 시 평균 0.56 mSv, 5 Gy 조사 시 평균 1.23 mSv의 중성자 발생하였다. Wedge Filter를 사용하여 중성자의 발생을 측정한 결과 Wedge Filter를 사용했을 때 중성자의 발생이 증가하였다. 고선량을 요구하는 SRS Cone을 사용했을 때에는 기존의 실험결과 보다 많은 중성자가 검출되었다. 속중성자의 경우 광자 5 Gy 조사 시 평균 2.85 mSv, 열중성자의 경우 광자 5 Gy 조사 시 평균 1.37 mSv의 중성자가 발생하였다. 일반 치료 시 광자 5 Gy 조사했을 때 보다 속중성자의 경우 약 1.6배, 열중성자의 경우 약 1.12배 정도의 중성자가 더 발생하는 것으로 나타났다. This study is to measure the radiation dose of neutrons generated by the particle accelerator during X-ray (photon) treatment with a neutron detection method by using CR-39, and to research how the generation of neutrons may incur problems associated with radiation doses for patient treatment when using high energy photons for cancer treatment as a clinical application. The findings are summarized as follows : The results showed that average 0.35 mSv was measured with exposure of 1 Gy photon in case of fast neutron, 0.65 mSv with exposure of 2 Gy photon, 1.82 mSv exposure of 5 Gy, 0.26 mSv with exposure of 1 Gy photon in case of thermal neutron, 0.56 mSv with exposure of 2 Gy photon, and 1.23 mSv with exposure of 5 Gy of photon. By measuring the occurrence of neutron by using Wedge Filter, it has been confirmed that the occurrence of neutrons increased when using Wedge Filter. The results also showed that more neutrons were detected over the existing experiments when using an SRS Cone requiring high doses of radiation. Total 2.85 mSv neutrons were found on the average with exposure of 5 Gy photon in case of fast neutron and 1.37 mSv neutrons were found on the average with exposure of 5 Gy photon in case of thermal neutron. During the general treatment, about 1.6 times more neutrons over 5 Gy photon were found in case of fast neutron and about 1.12 time more neutrons over 5 Gy photon were found in case of thermal neutron.

박철수(Park Cheol-Soo),한용수(Han Yong-Soo) 대한치료과학회 2019 대한치료과학회지 Vol.11 No.2

Objective: In order to optimize the image acquisition time in the T1 3D SPACE Sequence when using Gd contrast media, the Signal Intensity was studied by Gd Phantom experiment by contrast media concentration according to the difference between Partial Fourier and Average. Method: Eight phantoms(10, 8, 6, 4, 2, 0.9, 0.5, 0.1 mmol) were used to evaluate the difference in Signal Intensity according to the difference between Partial Fourier and Average in the T1 3D SPACE Sequence. Partial Fourier was applied to 6/8, 7/8, and 8/8 based on Average 2.0, and Average 1.5, 1.7, 1.9 and 2.0 were applied to Partial Fourier 8/8. Results: The phantom Signal intensity of 10 mm, 8 mmol, 6 mmol, 4 mmol contrast medium decreased with increasing Partial Fourier and Average parameters. In the correlation analysis results for each factor, Partial Fourier and Average showed a strong negative correlation in the Signal Intensity correlation. 2 mm, 0.9 mm, 0.5 mmol, 0.1 mm contrast agent phantom Signal intensity was measured. As the value of Partial Fourier and Average increased, Signal intensity increased. In the correlation analysis results for each factor, Partial Fourier and Average showed a strong positive correlation in Signal Intensity correlation. Conclusion: In order to set the optimal scan time in T1 3D SPACE Sequence and maximize the contrast effect, apply the experimental result showing the maximum Signal intensity at 0.5 mmol and simultaneously reduce Partial Fourier and Average. Significant increase in Signal intensity was confirmed.
