Today, museum exhibition can be divided into two sub-categories: a. informative exhibition with various useful auxiliary media to convey knowledge and b. appreciative exhibition considering aesthetic conveyance and visual/perceptual environment. In addition to this, the concept of memorial exhibition as a field that tangible and intangible memories are transmitted and reproduced is creating another genre of exhibition. As an example of such a memorial exhibition above, the work of de-constructive architect Daniel Libeskind was selected. Jewish Museum and Imperial War Museum North both of which maximized the exhibition space by grafting architectural language to exhibition narrative were analyzed and compared to see if the same architectural language can be displayed differently in another form of exhibition after being drawn into the exhibition space depending on the changes in time and perspective. Therefore, in the narrative display combining the selection of exhibition contents and storytelling, the formative language of space can confirm that exhibition narrative as an ending structure changed into a retelling story with more extended meanings through interactive factors. Eventually, in this formative narrative, when the display of historical facts and exhibition themes is combined with the architectural language in an exhibition hall according to the approach direction, the memorial exhibition can create a formative language stimulating sensibility in the memories of space and a differentiated formative exhibition space where one is truly moved by oneness of contents.

In this work, simultaneous measur of space charge and conduction current was c out in LDPE with air gap by Pulsed-Electro-Aco Method. Also, effect of long time charging at con electric field on the formation of space charge conduction was investigated. From the experim results. we knew that the homo space charge formed near the dielectric surfaces and moving the bulk of dielectric as the electric field elevated. This was related with the deep traps b carriers and de trapping by Poole-field lowering conduction current was coincident with the Pool emission. From the long time charging experimen obtained the results that the negative space was moving into the dielectric bulk as the cha continued and the positive space charge accumulated at upper surface of LDPE.

Focused on developing form of Western architecture, invisible elements covering actual human life has been dealt with separately and the time was turned away and disparaged. But now the phenomenology, arranging such a meeting of space and time, gives opportunity to look at the actual life in architecture. Recently, Guille Deleuze and Merleau-Ponty tried to recover the sense of touch segregated in skin from body keeping eyes for distance. And the activity can be happened by being connected to the body rather than to eye in the space. From the phase of recognition where the human body tries to identify the object in the space considering a time, it will be changed for the subject to the phase of space-time structure. If the tactility is to erase the distance different from the visuality in dichotomy, it will be occurred to having a tension and makes new relationship to work trying to move the subjective point of view in object. Like this evidence in analysis of architecture, it can be found these in the Korean traditional architecture rather than Western architecture in terms of emphasizing the time and space. And this study will be intensive to the side of the Phenomenology how it is being connected to the movement in the space and time for the subject and object.

Moon mineralogy mapper ($M^3$)'s work proved that the moon is not completely dry but has some hydroxyl/water. $M^{3{\prime}}s$ data confirmed that the amount of hydroxyl on the lunar surface is inversely related to the measured signal brightness, suggesting the lunar surface is sensitive to temperature by solar insolation. We tested the effect of solar insolation on the local distribution of hydroxyl by using $M^3$ data, and we found that most craters had more hydroxyl in shade areas than in sunlit areas. This means that the local distribution of hydroxyl is absolutely influenced by the amount of sunshine. We investigated the factors affecting differences in hydroxyl; we found that the higher the latitude, the larger the difference during daytime. We also measured the pyroxene content and found that pyroxene affects the amount of hydroxyl, but it does not affect the difference in hydroxyl between sunlit and shaded areas. Therefore, we confirmed that solar insolation plays a significant role in the local distribution of hydroxyl, regardless of surface composition.

In this paper for an object grasped by a robot hand to work in stiffness control domain we first investigate the number of fingers for successful stiffness modulation in the object operational space. Next we propose a new compliance control method for robot hands which consist of two steps. RIFDS(Resolved Inter-Finger Decoupling Solver) is to decompose the desired compliance characteristic specified in the op-erational space into the compliance characteristic in the fingertip space without inter-finger coupling and RIJDS(Resolved Inter-Joint Decoupling Solver) is to decompose the fingertip space without inter-finger coupling and RIJDS(Resolved inter-Joint Decoupling Solver) is to decompose the compliance characteristic in the finger-tip space into the compliance characteristic given in the joint space without inter-joint coupling. Based on the analysis results the finger structure should be biominetic in the sense that either kniematic redundancy or force redundancy are required to implement the proposed compliance control scheme, Five-bar fingered robot hands are used as an illustrative example to implement the proposed compliance control method. To show the effectiveness of the proposed compliance control method simulations are performed for two-fingered and three-fingered robot hands.

The purpose of this study was to analyze daylighting performance in a semi-infinite size office space for lighting energy conservation. DOE2.1E was used for simulations for the model space of $12\times12\times2.6m$. Nomographs were developed which could simulate work plane illuminance, glare index, energy consumption rate and energy reduction rate for daylighting design. Major results of simulations are as follows ; 1) When blinds facing south were installed, 43% of workplane illuminance diminished, but the flare index didn't exceed the recommended max-glare value. 2) In a semi-infinite office space facing south. energy consumption rate in the case space of 500 lux workplane illuminance is larger then case space of 300 lux workplane illuminance. Therefore, energy reduction rate is increased when the semi-infinite office faces south and naintains 300 lux workplane illuminance level.

As regards of designing, I chose a simple wall design of repeating pattern of vertical windows, rather than making the building as a glamourous obzet. This kind of approach was intended to pursue strong image of construction company, interchanging and communicating with its confused surrounding. Therefore, I boldly removed parts that I considered needless from the facade, and used simple and easy words clearly implying the organization. Lobby is the face of the building, but since the space is deep and narrow and the reality of lease should be considered, there was limit to give original image to the lobby. Instead, high ceiling is the biggest feature of this space. Doorae Engineering-Construction Corp. is young and energetic company. I wanted to highlight the young and energetic image of the company by crossing tore oblique piece of boards. This doesn't just has a simple function as ceiling, but also work as a major subject in the space. In addition of this powerful space of oblique lines, indirect lighting is used to emphasize the character of territory, continuity and deepness of the space. Character of territory that divides main and supplementary function and main and supplementary moving line is expressed by flow of dimension, and continuity and deepness of space is emphasized by indirect lighting flowing linearly through the crack between the ceiling and the wall.

The existing art museums existed for preservation and exhibition of collected material and the work which has artistic value. But today the art museum is not just for preservation and exhibition. It takes charge of public education as opened place to public. Further, it wants to be the art museum that the visitors who visit the art museum can enjoy and participate. The role change of like this is judged with the inevitable result which follows in many social demand. And increase with interest of leisure and culture life and continued demand for education, the role of modern art museum is becoming wider. Llike this, to accomplish these roles, space configuration of the modern art museum is changing. In the future, to meet more social demands and to solve flexibly, the modern art museum must concern more spacial efforts. Therefore, to grasp the change and the aspect of modern art museum, this study analyzes the Jeonbuk Province Art Museum, the Gyeongnam Art Museum and the Gyeonggido Museum of Art, They are most recently opened museum after 2000. To grasp space configuration of these museums, space syntax was used. And with the result which is analyzed, as grasps the problem and suggest an alternative idea, it can suggest advanced and proper direction.

The unexpected observation condition or insufficient measurement modeling can lead to uncertain measurement errors. The uncertain measurement error of orbit determination problem typically consists of noise, bias and drift. It must be removed by using a proper estimation process for better orbit accuracy. The estimation of noise and drift is not easy because of their random or unpredictable variation. On the other hand, bias is a constant difference between the mean of the measured values and the true value, so it can be simply removed. In this study, precision orbit determination with SLR observations considering range bias estimation is presented. The Yonsei Laser-ranging Precision Orbit Determination System (YLPODS) and SLR NP (Normal Point) observations of CHAMP satellite are used for this work. The SLR residual test is performed to estimate the range bias of each arc. The result shows that we can get better orbit accuracy through range bias estimation.

In order to assess the reliability of a building energy simulation program (TRNSYS) from the standpoint of user, a set of verification experiment and calculation of cooling load for a test space is carried out. This work is a complement of the previous study that dealt with heating load for the same space. The test space is kept airtight to eliminate the source of uncertainties in modeling. A window-mounted, on/off controlled air-conditioner is used for cooling, whose performance has been established a priori. The calculation encompasses two models for evaluating cooling load in TRNSYS: energy rate control and temperature level control. Comparison of the total cooling loads obtained from different sets of experimental data enables to validate the measurements. The experimental result shows that the latent load is fairly large even in the absence of apparent air change in the space, which needs to be clarified. Each of hourly and daily accumulated sensible loads is compared between the experiment and two calculation models. Despite an inconsistency associated with solar irradiation, both of the models agree favorably with the experiment within a tolerance, illustrating their capability of properly predicting space thermal loads.
