김신원(Shin Won Kim),박태석(Tae Seok Park),노희곤(Hee Gon Noh) 한국디자인문화학회 2009 한국디자인문화학회지 Vol.15 No.3

도시가 발전하면서 사람들은 삶에 있어 정신적, 문화적 욕구의 충족에 더 많은 관심을 가지게 된다. 도시환경을 개선하고자 하는 요구는 과거에 비해 더욱 심화되었다. 조경 분야에서 외부 환경의 물리적 요소는 이러한 요구에 부응하는데 있어 중요한 역할을 한다. 일반적으로 외부 공간을 형성하는 주요한 골격은 토지, 식물, 정형적 요소 등이다. 도시생활에서 이용자가 향유하는 공간으로는 주로 자연이 우세한 자연적 공간, 인공적 요소가 가미된 자연적 공간, 인공성이 주가 되는 자연적 공간 등이 있다. 이러한 공간은 사람들이 자연과 접하며 휴식하고 만나고 담소를 나누는 장소가 된다. 외부 공간은 실용적인 기능뿐만이 아니라 시각적인 아름다움도 지녀야 한다. 최근 들어 조경디자인 분야에서 공간을 구성하는데 질 높은 다양한 재료들이 활용되고 있다. 그런데 도시공원을 보면 특히 바닥포장과 관련해서는 개선해야 할 부분이 많이 있다. 시대의 흐름 및 도시민의 요구에 부응하여 빠른 시일 내에 도시공원 바닥포장 디자인의 개선이 이루어져야 하고 재료 선정에 변화가 있어야 한다. 도시공원의 바닥포장은 이용자의 쾌적성, 안전성, 접근성 등에 영향을 준다. 도시공원 바닥포장의 디자인 개선에 관한 본 연구는 쾌적한 도시공원을 위해 필요로 하는 바닥포장의 조성에 대한 연구이다. 연구방법은 선유도, 서울숲, 월드컵공원의 현황을 조사하여 바닥포장과 관련된 문제의 요인과 유형을 분석하고, 문제를 해결하고 공간의 질을 높이기 위해 바닥포장 개선 방안을 연구하여 설계안을 제시하였다. 도시공원 바닥포장의 품질 개선을 도모하며, 향후 도시공원 바닥포장 디자인의 수준을 제고하는데 유용하게 활용될 수 있는 자료를 제공하는 것에 본 연구의 의의와 목적이 있다. 연구를 수행하기 위하여 도시공원 바닥포장에 대해 현황 조사 및 분석이 이루어졌다. 또한 연구 결과를 토대로 하여 바람직한 바닥포장 재료 및 색채를 선정하고 적절한 바닥포장 디자인의 변경안을 제시하였다. 도시공원 바닥포장의 디자인 변경이 요구되는 현황을 조사하고 그 원인을 분석하여 개선안을 제시한 본 연구의 내용은 이용자가 만족할 수 있는 쾌적하고 아름다운 도시공간을 조성하는데 도움이 될 것이다. As cities continue to develop, people desire to fulfil their mental and cultural desires. So the demand for improving the city environment is more palatable than ever. The `outer-space` physical element in landscape architecture has its own role to play in satisfying this demand. The general frame of `outer-space` is mostly based on land, plants, and formative factors, regardless of size, fixedness, or location. The space for leisure use is divided into three parts. The first is `natural space` including mountains, rivers, and seas. The second is `natural space with added artificial elements` such as parks and terraced land on the rivers, which are created to protect the natural space from probable damage and to make full use of the space as rest areas. The third is `purposeful space` such as squares and parks with environmental and human facilities. They are the spaces made for the purposes of resting, recreation, and/or indicating the border of inside or outside of buildings. The ideal function of the elements of outer space is not only providing beauty, but also playing an important role in determining the atmosphere of limited space like parks. With the rapidly changing social norm, the design period tends to get shorter and shorter, and the recent trend is to use materials with high quality and diversity. However, the design of pavement in city parks has not been remodeled. Great improvements to facility maintenance, repair work, and plant preservation in parks have been made, but the issue of remodelling pavement has hardly been considered. Given that the type of pavement can give comfort or stress to the people visiting parks, it plays an important role in park design. This study is to design and create surface pavement for improving the outdoor spatial quality of city parks. The specific goals and objectives of this study are: to develop design criteria for creating user-responsive outdoor space, based upon the research findings drawn from site survey and analysis focusing on the surface pavement in city parks; and to make specific design recommendations, if there is room for improvement, for improving the outdoor spatial quality of city parks. This research study focused on surface pavement in 3 city parks (Seonyu Island, Seoul Forest, World Cup Park) such as overall image, arrangement of pavement, design and pattern, material, and color. With this background, and with survey and analysis, this study will suggest design changes to pavement in order to make the public space of the city park more satisfying and comfortable to its users. Findings obtained from this research study could be used in the designing of future projects in order to get a better understanding of the needs of users. The changes in order to meet users` needs and to improve the spatial quality of the city parks should be implemented.

조경직 공무원의 직무특성 및 직무만족 인식에 관한 연구

박태석,김신원,Park, Tae-Seok,Kim, Shin-Won 한국조경학회 2016 韓國造景學會誌 Vol.44 No.6

조경 체계의 중심이 되는 정부에서도 조경 조직의 직제 운영이 미흡하다. 지방정부의 경우, 조경직 공무원을 채용하고 있으나, 운영상에 있어서는 임업직으로 운영하는 등 관리운영의 문제점과 제도운영의 취약성이 있다. 본 연구는 우리나라 조경직 공무원 행정제도 분석과 조직문화 행태의 만족도를 분석하였다. 이에 조경직 공무원의 직무만족 향상을 위한 실천적인 자료를 제공하고, 조경의 위상을 제고하는데 그 목적이 있다. 본 연구는 첫째, 현재 조경직 공무원의 조직 문화 행태와 직무의 적정성 그리고 타 직렬 공무원들과 어떤 차이가 있는지 설문조사를 실시했다. 설문조사 분석 결과, 조경직 공무원으로서 직무만족은 대체로 높으나, 집권화 즉, 상관의 지시 명령, 자율성 제한 등은 강한 것으로 나타났다. 둘째, 조경직 공무원의 조직문화 행태 및 직무만족 향상을 위해 연구 분석을 실시하고 기존의 행정자치부(2006) 선행연구 자료와 차이를 비교분석하였다. 그 결과, 조경직 공무원이면서 임업관련 직무를 많이 하고 있는 그룹이 상대적으로 조직몰입 만족도가 낮은 것을 확인할 수 있었다. 따라서 조경직 공무원의 조경 전문성 확보가 필요한 것으로 분석되었다. 셋째, '조경직 직무환경', '조경직 법적 제도' 그리고 '조경직 직무분장'에 미치는 영향을 종합적으로 분석하였다. 조경직 공무원으로서 갖는 의의를 직무에 부여하여, 가치체계는 높은 만족도를 가지고 있는 것으로 나타났다. 그러나 조경직 직제의 독립성 부족, 조경직 법적 제도의 위기성, 낮은 채용 등 조경직제와 관련된 만족도는 낮게 분석되었다. 넷째, 현재 조경직 공무원이 조경업무가 아닌 임업, 건축, 도시계획, 행정 등의 직무를 처리하고 있어, 전문성을 제대로 살리지 못하고 있는 실정이다. 따라서 통계학적 변수에 따라 조경직 공무원의 직무만족에 차이가 있는지를 분석하였다. 조경 직무에 전공자의 전문성을 확보해야 '조경직 법적 제도', '조경직 직무만족', '조경직 조직몰입도'가 높아진다는 것을 알 수 있었다. 본 연구를 통하여 다음과 같은 향후 연구 과제를 제시할 수 있다. 첫째, 조경직 공무원의 직무분장 정체성 확립, 둘째, 조경직제에 의한 조직구성 확립 등으로 요약할 수 있다. 따라서 이러한 과제들이 행정적으로 수렴되고, 정책에 반영될 수 있도록 조경과 관련된 모든 이해관계자들의 실질적인 대응전략이 필요하다. In the case of the government, which plays a pivotal role in the landscape architecture system, the management of positions in landscape architectural organizations is lacking. At the local government level, while public officials for managing landscape architecture are being hired, there are problems and vulnerabilities in both management and system operations as such public officials recruited for positions in landscape architectural services operate under the forestry service. Accordingly, this study analyzed the Korean administrative system of public officials in the landscape architectural service and their satisfaction with the organizational culture and behavior. The aim was to provide practical data for improving the job satisfaction of public officials in landscape architectural service and enhance the status of landscape architecture. First, a survey was conducted regarding current organizational culture/behavior and job adequacy, and differences when compared to different job series with regards to the public officials in the landscape architectural service. The results indicated that job satisfaction of those in landscape architectural service was generally high, but they showed strong centralization, i.e., orders from superiors and limitations on autonomy. Second, an analysis was conducted to improve the organizational culture/behavior and job satisfaction of public officials in the landscape architectural service, and a comparative analysis was conducted on the differences between the analysis result and preceding studies by the Ministry of Government Administration and Home Affairs(2006). The results indicated that organizational commitment/satisfaction of public officials in the landscape architectural service was relatively low among those who had a great amount of work experience related to forestry. Therefore, it was shown that it is necessary to ensure expertise in landscape architecture. Third, a comprehensive analysis was conducted regarding the influences on "working environment", "legal system" and "job allocation" in regard to public officials in land architectural service. The results indicated that satisfaction in the value system was high when given significance to the job as public officials in land architectural. However, their satisfaction in the land architectural system was low due to the lack of independence in their positions, the vulnerable legal system of land architectural service and low employment rates. Fourth, current public officials in landscape architectural service process tasks such as forestry, architecture, city planning and administration that are not related to their area of expertise. Therefore, an analysis was conducted on whether there is a difference in the job satisfaction of public officials in landscape architectural service according to statistical variables. It was identified that "legal system", "job satisfaction" and "organizational commitment" with regard to public officials in landscape architectural service can be improved through ensuring their expertise. This study suggests the following tasks to further inquire into landscape architecture in general. First, establish an identity of work allocation for public officials in the landscape architectural service, and second, establish an organizational constitution according to the positions in landscape architectural service. Accordingly, it is necessary for interested parties of landscape architecture to devise practical strategies so that such tasks can be converged administratively and reflected in policies.

박송이,김태훈,이성래,김동환,남궁석,장태석,Park, Song-E,Kim, Tae-Hoon,Lee, Seong-Rae,Kim, Dong-Hwan,NamKung, Seok,Jang, Tae-Suk 한국분말야금학회 2011 한국분말재료학회지 (KPMI) Vol.18 No.1

Effect of Cu content on microstructural and magnetic properties of a $(Nd_{26.06},Dy_{6.51})Fe_{bal.}$ $Cu_xB_{0.97}$(wt.%), (x = 0.2, 0.3, 0.4, 0.5) strip-cast was studied. The average inter-lamellar spacing in the free surface and wheel side of the strip cast increased as the Cu content increases. The grain uniformity, the grain alignment, and (00L) texture of the strip cast increased with Cu contents up to 0.4 wt.%. These microstructural changes were attributed to the decrease of the effective cooling rate of the melted alloy caused by the decrease of the melting temperature of resulting from Cu addition. Coercivity and remanence were increased because of the grain alignment and (00L) texture improvement with Cu contents up to 0.4 wt.%.

Objective : Physiological evidence regarding acupuncture's effect in human patients is not yet well established, despite considerable evidence for its therapeutic efficacy. Besides target or disease specificity of acupuncture, acupuncture analgesia (AA) appears to be another large subclass that poses many questions, such as whether there is point specificity with respect to which acupoint is most effective for a particular condition. Methods : We observed brain activation with functional magnetic resonance imaging (fMRI) using a set of stimuli that consist of pain, pain following Meridian acupuncture, and pain following Sham acupuncture. Results : Among the new observations, the most interesting fact is that data sets of both Meridian acupuncture and Sham acupuncture show decreased activation of the same brain areas related to the pain processing signals. Present functional MRI study demonstrate two important biological observations that could elucidate AA mechanism in human participants: the effects of acupuncture occur through mediation of the higher brain areas. Sham acupuncture stimulation appears to be almost as effective as traditional Meridian acupoint stimulation, suggesting that acupuncture is not entirely point specific. Decreased activation in the limbic paleo cortical areas appears to be the probable neurological manifestation of AA and strongly implies that acupuncture stimulation inhibits the transmission of ascending pain signals to the higher cortical areas by the previously known descending pain inhibitory circuit. Conclusion : We, therefore, a hypothesized that this pain inhibitory circuit is initiated and mediated via the broad sense Hypothalamus Pituitary Adrenal (BS HPA) axis in conjunction to the "sensory stimulation."

강영훈,김봉석,태원필,김기출,서수정,박태석,김용성,Kang, Young-Hun,Kim, Bong-Seok,Tai, Weon-Pil,Kim, Ki-Chul,Suh, Su-Jeung,Park, Tae-Seok,Kim, Young-Sung 한국세라믹학회 2006 한국세라믹학회지 Vol.43 No.2

We studied the microstructure and magnetic property of the pulsed DC magnetron sputtered $Zn_{\0.8}Co_{0.2}O$ film as a function of substrate temperatures. The X-ray patterns of the $Zn_{\0.8}Co_{0.2}O$ film showed a strong (002) preferential orientation at $500^{\circ}C$. The films with a crystallite size of 23-35 nm were grown in the form of nano-sized structure and this tendency was remarkable with increasing substrate temperature. The UV-visible result showed that the $Zn_{\0.8}Co_{0.2}O$ film prepared above $300^{\circ}C$ has a high optical transmittance of over $80\%$ in the visible region. The absorption bands were observed due to sp-d interchange action by $Co^{2+}$ complex ion and dd transition in the region from 500 to 700nm. The resistivity of the film was below $10^{-1}\;\Omega-cm\;above\;300^{\circ}C$. The AGM analysis results for the all films showed the magnetic hysteresis curves of ferromagnetic nature. The low electrical resistivity and room temperature ferromagnetism of ZnCoO thin films 'deposited above $300^{\circ}C$ suggested the possibility for the application to Diluted Magnetic Semiconductors (DMSs).

고윤덕,태원필,김응권,김기출,최춘기,김종민,송준태,박태석,서수정,김용성,Ko, Yoon-Duk,Tai, Weon-Pil,Kim, Eung-Kwon,Kim, Ki-Chul,Choi, Choon-Gi,Kim, Jong-Min,Song, Joon-Tae,Park, Tae-Seok,Suh, Su-Jeung,Kim, Young-Sung 한국세라믹학회 2005 한국세라믹학회지 Vol.42 No.7

Zn$_{l-x}$Co$_{x}$O (x = 0.05 - 0.20) films were grown on Coming 7059 glass by sol-gel process. A homogeneous and stable Zn$_{l-x}$Co$_{x}$O sol was prepared by dissolving zinc acetate dihydrate (Zn(CH$_{3}$COO)$_{2}$$\cdot$2H$_{2}$O), cobalt acetate tetrahydrate ((CH$_{3}$)$_{2}$$\cdot$CHOH) and aluminium chloride hexahydrate (AlCl$_{3}$ $\cdot$ 6H$_{2}$O) as solute in solution of isopropanol ((CH$_{3}$)$_{2}$$\cdot$CHOH) and monoethanolamine (MEA:H$_{2}$NCH$_{2}$CH$_{2}$OH). The films grown by spin coating method were postheated in air at 650°C for 1 h and annealed in the condition of vacuum (5 $\times$ 10$^{-6}$ Torr) at 300$^{\circ}C$ for 30 min and investigated the nature of c-axis preferred orientation and physical properties with different Co concentrations. Znl_xCOxO thin films with different Co concentrations were well oriented along the c-axis, but especially a highly c-axis oriented Zn$_{l-x}$Co$_{x}$O thin film was grown at 10 at$\%$ Co concentration. The transmittance spectra showed that Zn$_{l-x}$Co$_{x}$O thin films occur typical d-d transitions and sp-d exchange interaction became activated with increasing Co concentration. The electrical resistivity of the films at 10 at$\%$ Co had the lowest value due to the highest c-axis orientation. X-ray photoelectron spectroscopy and alternating gradient magnetometer analyses indicated that no Co metal cluster was formed, and the ferromagnetic properties appeared, respectively. The characteristics of the electrical resistivity and room temperature ferromagnetism of Zn$_{l-x}$Co$_{x}$O thin films suggested the possibility for the application to dilute magnetic semiconductors.
