본 논문은 기존 연구에서 전통마을의 공간구성을 분류한 연구들을 일별해 보고, 그것들을 보완하여 새롭게 전통마을의 공간구성과 속성을 정리하였으며, 다음으로는 새롭게 정리된 공간구성 분류에 맞추어 기존연구를 활용하되 필자가 강조하고자 하는 사항을 보안하여 한국 전통마을의 공간 구성을 재론한 것이다. 먼저 전통마을의 공간구성으로 ①자연공간 ②주거공간 ③생업공간 ④이동공간 ⑤경계공간 ⑥놀이공간 ⑦제의공간의 7가지를 추출하였다. 그리고 그것을 기본성격에 맞추어, ①마을입지의 기본 공간 : 자연공간 ②자연공간 하에서 요청되는 필수 생존공간 : 주거공간 및 생업공간 ③마을 구성원 상호소통망에서 파생된 관계공간 : 이동공간 및 경계공간 ④장(場)의 개념으로 확산되는 가변공간: 놀이공간 및 제의공간의 4개 요소로 다시 제시하여 서술하였다. 사람이 만든 공간은 사람들의 삶을 담는 그릇이다. 그 그릇이 편리하고 쓰임새 있는 그릇이 되기 위해서는 삶의 틀에 맞추어진 것이어야 한다. 우리의 전통마을의 공간구성은 구성원들의 자연관·생활양식·세계관이라는 삶의 틀에 잘 구현되어 있었다. 자연관은 마을 공간구성 전체에 작용하지만 특히 자연공간에 잘 반영되어 있다. 생활양식은 주거공간·생업공간·이동공간·놀이공간에, 그리고 세계관은 경계공간·제의공간에 특색있게 반영되어 있다. 이러한 모든 것들을 유기적으로 작동시키기 위하여 공동체적 규약이 있었다.

The purpose of this study is to grasp the change of modern space concept and analyze how to adopt and embody the change in modern fashion. The study researched wearer's costume space and analyzed space shown in supermodern fashion design by classifying it into response to non-space, allowance of wearer-based space, scientific space of architectural skill and embodiment of space image. As a study method, literature and study material of sociology, anthropology, fashion sociology and design field were referred. For picture data of supermodern fashion work, specialized book, designer, brand collection material and internet site pictures were collected and analyzed. The study result shows the following features of fashion design space embodiment corresponding to the change of supermodern environment. First, supermodern design secures closet space like pocket for portable objects and uses design space in order to provide the space for convenience of movement. Second, supermodern design creates wearer-based independent space in order to secure person's physical and mental stability in city environment. Third, supermodern design uses space scientifically from the aspect of detail and shape by applying space of architectural skill to space. Fourth, supermodern design shows aesthetic feature that embodies interpretation of space by conceptualizing space image and using fashion.

The present study investigated counseling services and work conditions perceived by counselors in Healthy Family Support Centers. Questionnaire survey by mail was used to collect data from 32 counselors in Healthy Family Support Centers. Major findings of this study were as follows. First, many counselors in Healthy Family Support Centers perceived work load of counseling services heavily though they thought counseling work attractive and they would keep on working. Second, many counselors had a positive view of work conditions as a workplace but not a few of them complained about physical work conditions including poor facilities like lack of counseling room space in Centers. In addition to this, many suggestions were proposed to improve the counseling services and work conditions perceived by counselors in Healthy Family Support Centers.

Recently, construction in downtown is often done closely at the adjacent building. In this case, underground construction need to Basement Composite Wall(BCW) construction. However, generally, during the construction process of BCW form works have many problems that are narrow working space and inefficient time consuming. Despite of these problems, there was no quantitative research for the work time of BCM assembly. Therefore, in this study, work time of CBW form assembly in underground construction is identified by the work analysis. The results of this study reveal that buttress work of basement form take lots of time in the entire work process of Basement Composite Wall form assembly.

The Korean nuclear industry developed the SPACE (Safety and Performance Analysis Code for nuclear power plants) code and this code adpots two-phase flows, two-fluid, three-field models which are comprised of gas, continuous liquid and droplet fields and has a capability to simulate three-dimensional model. According to the revised law by the Nuclear Safety and Security Commission (NSSC) in Korea, the multiple failure accidents that must be considered for accident management plan of nuclear power plant was determined based on the lessons learned from the Fukushima accident. Generally, to improve the reliability of the calculation results of a safety analysis code, verification work for separate and integral effect experiments is required. In this reason, the goal of this work is to verify calculation capability of SPACE code for multiple failure accident. For this purpose, it was selected the experiment which was conducted to simulate a Multiple Steam Generator Tube Rupture(MSGTR) accident with Passive Auxiliary Feedwater System(PAFS) operation by Korea Atomic Energy Research Institute (KAERI) and focused that the comparison between the experiment results and code calculation results to verify the performance of the SPACE code. The MSGR accident has a unique feature of the penetration of the barrier between the Reactor Coolant System (RCS) and the secondary system resulting from multiple failure of steam generator U-tubes. The PAFS is one of the advanced safety features with passive cooling system to replace a conventional active auxiliary feedwater system. This system is passively capable of condensing steam generated in steam generator and feeding the condensed water to the steam generator by gravity. As the results of overall system transient response using SPACE code showed similar trends with the experimental results such as the system pressure, mass flow rate, and collapsed water level in component. In conclusion, it could be concluded that the SPACE code has sufficient capability to simulate a MSGTR accident.

A new algorithm for planning a collision-free path is developed based on linear prametric curve. In this paper robot is assumed to a point, and two linear parametric curve is used to construct a path connecting start and goal point, in which single intermediate connection point between start and goal point is considered. The intermediate connection point is set in polar coordinate(${\theta}{\delta}$) , and the interference between path and obstacle is mapped into CPS(connection point space), which is defined a CWS GM(circular work space geometry mapping). GM of all obstacles in workspace creates overlapping images of obstacle in CPS(Connection Point Space). The GM for all obstacles produces overlapping images of obstacle in CPS. The empty area of CPS that is not occupied by obstacle images represents collision-free paths in Euclidian Space. A GM based on connection point in elliptic coordinate(${\theta}{\delta}$) is also developed in that the total length of path is depend only on the variable .delta.. Hence in EWS GM(elliptic work space geometry mapping), increasing .delta. and finding the value of .delta. for collision-free path, the shortest path can be searched without carring out whole GM. The GM of obstacles expersses all possible collision-free path as empty spaces in CPS. If there is no empty space available in CPS, it indicates that path planning is not possible with given number of connection points, i.e. path planning is failed, and it is necessary to increase the number of connection point. A general case collision-free path planning is possible by appling GM to configuration space obstacles. Simulation of GM of obstacles in Euclidian space is carried out to measure performance of algorithm and the resulting obstacle images are reported.

본 연구는 크리스토의 작업을 사례로 하여 환경디자인에 있어서 공간연출의 의미와 그 형태를 다루고 있다. 환경디자인에 있어서 공간연출의 역할은 매우 중요하지만 구체적으로 어떤 형식을 다루기는 힘들다. 특히 이러한 측면에서 발생하는 환경예술과 디자인의 영역의 구분 역시 매우 모호하다. 이에 여기에서는 크리스토의 작품을 사례로 하여 적용되는 공간연출의 형식을 살펴보고 환경디자인에 있어 필요한 방법으로 적용하고자 한다. 크리스토의 작업은 크게 3가지로 구분될 수 있는데, 환경포장, 환경설치, 환경분할이다. 여기에서 사용된 공간연출방식은 연극적이며, 과정-참여적이며, 장소성이 강조됨과 동시에 다양한 오브제를 활용방식으로 정리할 수 있다. 그의 작업에서 나타난 환경적 오브제연출, 상황으로서의 공간연출이나 공간연출을 구조화하는 방식은 환경디자인에 있어서 매우 유효하며 아울러 그에 대한 새로운 미학적 가치평가가 가능해진다. 이러한 크리스토의 작업을 통해서 유추해낼 수 있는 공간연출의 방식은 환경디자인의 작업과정에 있어서 매우 유효할 것으로 생각된다.

Motivated by optimization considerations we revisit the work by Dontchev in [7] involving the convergence of Newton's method to a solution of a generalized equation in a Banach space setting. Using the same hypotheses and under the same computational cost we provide a finer convergence analysis for Newton's method by using more precise estimates.

We present the high-resolution near-infrared spectra of standard stars observed with Immersion Grating Infrared Spectrograph (IGRINS). IGRINS covers the full spectral range of H and K bands simultaneously with a high spectral resolution (R=40,000), revealing many previously undetected and/or unknown lines. In this work, we present preliminary results of spectroscopic diagnostics for stellar physical parameters. Our ultimate goal is to provide a library of near-infrared spectra of standard stars, which covers all spectral types and luminosity classes, with a high-resolution and high signal to noise ratio ($SNR{\geq}200$).
