Hamburg is going with the HafenCity Project to create new urban space for city's bustling central district. HafenCity will add an additional 155 hectares to Hamburg's central urban area, increasing its total area by some 40 percent. The new developments in HafenCity will be oriented towards the River Elbe and the great seaport. Its centre will have a close relation to water. They will be used for the construction of a fascinating mix of residential accommodation, offices, cultural and leisure amenities, retail facilities and restaurants set in a framework of an elaborate urban layout. This study is focusing on the purpose of the project goals, the task of the Hamburg authorities and GHS (Gesells chaft f$\ddot{u}$r Hafen und Standortentwicklung) and an urban planning ideas competition (draft masterplan). Regarding of the new trend of the reurbanisation in Europe, the aim of this study will be to find out, in which way Hafencity is trying to develope the new city district as a model for the European inner city of the 21st century.

Hakbongjongtaek(The head house of Uisong Kim family, 鶴峯宗宅), firstly built in the early 17th century, was moved to its neighboring place in the late 18th century. The man who led the relocation(移建) of the house was the eldest grandson of the family, Jong-soo, Kim. He made and overall plan and also participated in building the house. There remain four Gados(family paintings, 가도(家圖)) related to the relocation plan. This paper aims to make an analysis of these Gados, and through analysis, to find what was the essential poing of the relocation plan and how the point was represented in the paintings. The result of analysis is as follows: 1. The main focus of relocation plan was the form of Anchae(the inner house). Anchae was designed as asymmetrical form, and restricted to four kan. Only Andaechung needed to be 6 kan size for religious ceremonies. 2. For the design of Sarangchae, the displacement of large Sarangbang and small Sarangbang was an important issue. There were two ways of layout: parallel type and facing type. The latter was chosen. 3. The representation and techniques of Gado is quite concrete, in spite of differences among them. The expression of doors, windows, attic and kitchen was based on the understanding of space. Also the spatial division, which was expressed line on the grid, was based on the scaled ruler. As we've seen before, painting the relocation plan was a kind of endeavors to make the housing type as a realization of Garye. Also, we can find out that role of the eldest grandson of the family was quite important to carry out the plan. As well as, it was meaningful to examine Sadaebu (the aristocrat of Chosun)'s perception of housing.

The office is an excellent candidate for implementing daylighting techniques because of the relatively high electric lighting power densities and long daytime use pattern. The quantity of light available for a space can be translated in term of the amount of energy savings through a process of a building energy simulation. To get significant energy savings in general illumination, the electric lighting system must be incorporated with a daylight - activated dimmer control. A prototype configuration of an office interior has been established and the integration between the building envelope and lighting and HVAC systems is evaluated based on computer modeling of a lighting control facility. First of all, an energy-efficient luminaire system is designed for both a totally open-plan office interior and a partitioned office. A lighting design and analysis program, Lumen-Micro 2000 predicts the optimal layout of a conventional fluorescent lighting fixture to meet the designed lighting level and calculates unit power density, which translates the demanded amount of electric lighting energy. A dimming control system integrated with the contribution of daylighting has been applied to the operating of the artificial lighting. Annual cooling load due to lighting and the projecting saving amount of cooling load due to daylighting under overcast diffuse sky are evaluated by a computer software, ENER-Win. In brief, the results from building energy simulation with measured daylight illumination levels and the performance of lighting control system indicate that daylighting can save over 70 percent of the required energy for general illumination in the perimeter zones through the year. A 25 % of electric energy for cooling may be saved by dimming and turning off the luminaires in the perimeter zones.

Before occupation of an apartment housing, the builders are required to inform the test result of IAQ to the public. However, there is no simplified method to predict IAQ before measurement of pollutant concentration. In this study, a simplified way of predicting IAQ based on the distribution of indoor pollutant concentration is proposed. 7 different cases of air change rate have been simulated through CFD analysis to get the distribution ratio of each pollutant material and then simplified functions were used with CRIAQ1 values derived from CFD simulation to evaluate by comparing the influence of each material in the indoor pollutant concentration. Again, a lot of efforts which can improve the indoor air quality have been performed. Materials used in indoor space are labeled with their pollutant emission level. Installation of ventilation system in residential buildings will be regulated by a building codes sooner or later. But it is important to understand the fact that layout of walls, location or size of openings will influence the indoor air flow and pollutant concentration. And location of emitting material influences to indoor air pollutants distribution. But until now there is few recognition and consideration of these factors. Therefore, in this paper the effects of these factors is proved and some kind of guideline is made for designers after a comparison of typical apartment floor plan and a new type plan with their average pollutant concentration and its distribution of each room. CFD(Computational Fluid Dynamics) program was used to show the indoor air flow and pollutant concentration distribution. For this purpose, a typical $100m^2$ apartment floor plan was chosen as a case study model and several alternatives were reviewed to improve the IAQ performance. The simulation took place in the condition of natural ventilation through windows.

As the importance of health and school health grows, the purposes of this research are to investigate the differences between the characteristics and the utilization of the nurse's office of an elementary school in an urban area and the nurse's office of an elementary school in a rural area, and to provide the data for the planning of construction of a nurse's office convenient for students to use after grasping the regional characteristics. The methods of this research include the interview and the survey conducted to the heath teachers after visiting 20 nurse's offices in 13 eups and myeons, and examined and analyzed the differences between the characteristics and the utilization of the nurse's office of elementary schools in an urban area and the nurse's office of an elementary school. The nurse's offices of the elementary schools in Cheongwon, a rural area, are worse in access to health care institutions and in the connection to the placement than those of the elementary schools in urban areas, so most of eups and myeons were not allowed for easy access to medical service. Depending on the bad personal surroundings of each elementary student, mental stress and the lack of heal care of each student should be taken care of along with the educating of the parents and the children. Also because of the difficulties in access to the health care institutions, it is suggested that a lot of support and interest should be provided for the nurse's offices and that a lot of changes with functions should occur to the nurse's offices so that the nurse's office of an elementary school can play the role as a local health care institution. Besides, the health teachers also should be able to provide more professional medical services by taking in-service training courses.

The appearance of over 10,000 TEU containerships (so called Mega-containerships) is determined. In order to operate these ships effectively, the number of these calling ports will diminish, and then feeder ships will transport cargoes from the hub-ports where mega-containerships call to the destination ports. In the hub-ports, handling containers for mega-containerships become huger, thus it is important for terminals to deal with cargo handling as soon as possible. However, the present terminal layout might have the limitation of maximum throughput per time unit. And then the transit time at the ports become longer. Therefore, we investigate the effect on some different terminal layouts with new alternatives. Actually, we discuss the ship-to-berth allocation at some adjacent berths for mega-containerships on three types of terminal layouts. First one is the conventional type consisted by some linear berths, most container terminals in the world are normally this type. Second one is the indented type consisted by linear berths and indented berths which we can handle from both sides of mega-containership simultaneously. Third one is the floating type consisted by linear berths and the floating berth. On this type, mega-containerships can moor between linear and floating berths. The merits of this type are that we can also handle from both sides of mega-containerships simultaneously, and ships can go through between linear berth and floating berths. Thus it is easier for ships to moor and leave berths. Under such assumptions, we examine the numerical experiments. In most cases, the total service times on the indented type are the longest among three types, these on the floating type are the next longer. Those reasons are that these layouts have the differences of berth occupancy obtained by the time and space axes, and whether the precedence constraints of ship service order needs or not.

BIPV system is one of the best ways to harness PV module. The BIPV system not only produces electricity, but also acts as a building envelope. Thus, it has the strong point of increasing the economical efficiency by applying the PV modules to the buildings. Bifacial solar cells can convert solar energy to electrical energy from both sides of the module. In addition, it is designed as 3 busbar layout which is the same with ordinary mono-facial soalr cells. Therefore, many of the module manufacturers can easily produce the bifacial solar cells without changing their manufacturing equipment. Moreover, bifacial BIPV system has much potential in building application by utilizing glass to glass structure. However, the performance of bifacial solar cells depends on a variety of factors, ranging from the back surface to surrounding conditions. Therefore, in order to apply bifacial solar cells to buildings, an analysis of bifacial PV module performance should be carried out that includes a consideration of various design elements, and reflects a wide range of installation conditions. As a result it found that the white insulation reflector type can improve the performance of the bifacial BIPV system by 16%, compared to the black insulation reflector type. The performance of the bifacial BIPV was also shown to be influenced by inclination angle, due to changes in both the amount of radiation captured on the front face and the radiation transmitted to the rear face through the transparent space. In this study is limited design condition and installation condition. Accordingly follow-up researches in this part need to be conducted.

This research was undertaken to prove the relationship between street mall activation and architectural plan design. The research methodology was established based on the analysis of data of two existing street malls in Korea (Western Dome & LaFesta) and theoretical studies of outdoor space design. The findings from this study are the following: First, building blocks with segments in every 50m or so are ideal for detailed communication between visitors and building contents. Second, the ratio of width of main corridor and building height should be less than 1 to provide intimate feel and keep visitors' attention concentrated in the facility. Third, store unit should have more storefronts to be exposed more to passers-by and lead more pedestrian traffic. Fourth, shape of store unit would rather be wide and shallow, instead of narrow and deep, to have more exposure to the central corridor. Fifth, the building block of the busiest(most expensive) area that is usually at the main entrance area of street mall should be flexible to fit more smaller units to maximize the profitability. Sixth, the main entrance of store should face the main pedestrian corridor to induce the influx of visitors. Lastly seventh, anchor tenant that has strong name recognition is usually located on basement or higher level to induce pedestrian traffic into the mall, key tenants that are strong and familiar brand names should be located at the corner of building block with spacing to attract visitors, provide even distribution of traffic, and support wayfinding, and local tenant should be located at small units along the central corridor or remainder spaces occurred from building core layout.

Cheoungju International Craft Biennale is not just an art exhibition but more like a pubic festival which is including an experiential learning and a public participation section as well as a special exhibition and an international competition section. Thus it is strongly required to present an appropriate meaning and mood corresponding to each exhibition hall. The paper has examined the exhibition topics during the last 10 years and the plannings and contents to install the exhibition hall according the yearly topic and it has analyzed the comprehensive evaluations after the exhibition. The research scope is limited to the part related to the exhibition hall and facilities, which is including calculation of dimensions and layout, access and movement system, the appropriateness of the design and construction period, measure of applied technology appropriateness, post management as well as planning intent, estimation of the number of the visitors, preliminaries. With the results shown in the comprehensive evaluation and analysis, the paper has presented two issues, the one related to the procensure and preparation and the other related to the facilities. It is showed that both problems are due to the lack of expertise and it is necessary for the experts to participate from the first step of the procedure including planning for the successful exhibition. For the appropriate exhibition hall corresponding to the exhibition planning and scale, it is required to have the professional considerations of successful space and visitor's movement management, display environment, construction method, and post management. The study presents that architectural and interior design have to take an active part in constructing exhibition design in overall stage including the initial, practice, and evaluation stage.

The objective of this study is to test the applicability of the Information processing model suggested by Kaplan to the preferences of Korean people as well as to investigate the preference patterns of Korean people and the influencing factors on Korean preferences for the landscape. Photo - questionnaire survey was conducted twice to collect the data concerning the landscape preferences. The samples of the first survey were selected from the citizens of Seoul and the students of Seoul National University. The first survey focused on the preference patterns of Korean people while the emphasis of the second survey was given to the test of information processing model and the influencing factors on the preferences of Korean people. The samples of second survey were also selected from the students of Seoul National University. The photos in the photo - questionnaire for the first survey included the scenes representing both three landscape styles(Korean, Japanese and Western styles)and three landscape qualities such as the layout of space, the use of landscape plants and the use of stones and rocks. For the second survey, four informational factors such as complexity, coherence, legibility and mystery were selected for inclusion in the photos of photo - questionnaire. Respondents for both survey were asked to respond their preferences on the five - point Likers scale. The results of the study suggested that four informational factors influence significantly the preferences of Korean students. The study indicated that both the citizens of Seoul and the students of Seoul National University prefer water and vegetation to rock among the contents of landscape. Among the landscape styles, Japanese landscape style was most preferred and Western landscape style was more preferred than Korean traditional landscape style. In addition to informational factors, it was found that the contents of landscape and landscape style were also major influencing factors on the landscape preferences. The socio - economic backgrounds of respondents such as age, foreign travel experience, income, residency before the age 14, familiarity and respondent's experties in landscape architecture seemed to Influence the landscape preferences.
