This study investigates the difference of the cognitive approach of Korean and Chines of the space direction that modern Chinese space phrase 'N+shang'. For this, we defined the spatial meaning of the noun 'N' and space noun 'shang' then investigate the conditions when 'N+shang' means 'the substance interior direction' and 'the substance exterior direction'. Also via 'lou+shang', we conducted the survey to Korean and Chinese students in order to see the what kind of cognitive differences be shown when they approach and translate the space direction of 'N+shang' structure. As a result of the survey, we were able to find cultural difference of spatial approach of 'N+shang' between these two countries, Korean select the cognitive inference path; from the substance external direction to internal direction while Chinese select from internal to external.

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.

Rho et al.(2008) showed that the eccentricity parameter of a CME is an important indicator for forecasting CME geoeffectiveness. In this study we have tested a capability of the eccentricity parameter as an indicator of CME direction. For this work we considered 11 CMEs observed by both SOHO/LASCO and STEREO/SECCHI (2007-2008 from Temmer et al. 2009) coronagraphs. We have estimated earthward direction angles for these CMEs based on two different methods: (1) the eccentricity parameter from a single coronagraph SOHO/LASCO and (2) the triangulation technique using a pair of spacecrafts LASCO/STEREO-A and LASCO/STEREO-B. As a result, we have found that for 7 out of 11 CME events their direction angles are consistent with each other within $20^{\circ}$. This result demonstrates that the earthward direction based on the eccentricity parameter can be a good potential indicator for CME propagation direction.

This paper addresses the results of an experimental and analytical research of a helical coil spring subjected to dynamic behavior using space curve vector after considering elongation rate. Vibrations in helical coil spring can be divided into 3 modes such as vibrations of coil spring center axis' vertical direction. axis' horizontal direction, direction about center axis. However. these 3 modes are dependent one another and are characterized as coupled. The dependency was proved through both theoretically and experimentally analyzing the results of dynamic characteristics of coil spring center axis' vertical direction vibration by transfer matrix method using the governing equation of static equilibrium. Also this paper shows that pitch angle and active coils in coil spring affect the dynamic spring characteristics of the above 3 modes and are especially sensitive to the mode for vibration of axis' horizontal direction which most affects especially on dynamo stability of helical coil spring.

In this paper, we define some integral curves connected with a framed curve in Euclidean 3-space. These curves include framed generalized principal-direction curve, framed generalized binormal-direction curve, framed principal-donor curve and framed Darboux-direction curve. We obtain some relations between the framed curvatures of new defined framed curves and framed curvatures of given framed curve. By using the obtained relationships we give some characterizations for such curves. We also give methods for constructing framed helix and framed slant helix from planar curves.

The circular plate resting on Boussinesq's half-space model under axisymmetric loading is studied by a finite element procedure to evaluate the distribution of contact pressure between plate and elastic half-space. The displacement of half-space due to axisymmetric surface loading can be evaluated by double integration of Boussinesq's solution. On that case the analytical integration can be executed for the radial direction but the analytical integration for the circumferential direction is impossible and the numerical integration should be considered. With the radial integration we can get non-dimensional function. Then the numerical integration for the formula is executed for the circumferential direction and the results are approximated 5th order Polynomials by using the least square method. With these 5th order approximate formula, the flexibility matrix of half-space is constructed as the coefficient matrix of nodal contact pressure by the finite element procedures. Iteration procedures are attempted by using this method to determine the separated region.

We have investigated a relationship among the solar proton events (SPEs), coronal mass ejections (CMEs) and solar flares during the solar cycle 23 (1997-2006). Using 63 SPE dataset, we found that SPE rise time, duration time, and decrease times depend on CME speed and SPE peak intensity depends on the CME earthward direction parameter as well as CME speed and x-ray flare intensity. While inspecting the relation between SPE peak intensity and the CME earthward direction parameter, we found that there are two groups: first group consists of large 6 SPEs (> 10,000 pfu at >10 MeV proton channel of GOES satellite) and shows a very good correlation (cc=0.65) between SPE peak intensity and CME earthward direction parameter. The second group has a relatively weak SPE peak intensity and shows poor correlation between SPE peak intensity and the CME earthward direction parameter (cc=0.01). By investigating characteristics of 6 SPEs in the first group, we found that there are special common conditions of the extremely large proton events (group 1); (1) all the SPEs are associated with very fast halo CME (>1400km/s), (2) they are almost located at disk region, (3) they also accompany large flare (>M7), (4) all they are preceded by another wide CMEs, and (5) they all show helmet streamer nearby the main CME. In this presentation, we will give details of the energy spectra of the 6 SPE events from the ERNE/HED aboard the Solar and Heliospheric Observatory (SOHO), and onset time comparison among the SPE, flare, type II burst, and CME.
