In Germany, community based daycare facilities has been supported by long term care policies since the 1970s. With the legislation of Care Insurance, those policy has been developed further. As the use of daycare facilities decreased and the financial burden for consumers increased, administrators of facilities has been seeking for innovative programs and management methods in order to improve the service. For the same reason, policy makers have been pursuing new regulations of architectural standards of facilities. By looking at legislations (i.e., Law of Care Insurance, Law of Heim, and DIN18025) that stipulate architectural standard of facilities in Germany, this study will identify the development process of architectural change of daycare facilities. In addition, the study aims to contribute to the discussion on the use of day care facilities in Korea in terms of the legislation of Care Insurance soon to be introduced.

Heat Assisted Magnetic Recording (HAMR) is one of the most promising candidates for high density magnetic storages over 1 Tb/$in^2$ areal density. Since the precise light delivery to the head is a key factor to realize HAMR application, it is required to establish the light delivery using micro laser module and micro actuator. For the careful control of micro actuator, a laser module was designed including laser diode, optical fiber, collimating lens, and fabricated V-groove substrate. In addition, the basic aligning method between the laser module and HAMR head was studied by the detection of current change in photo diode due to the amount of reflected light from the head.

The purpose of this paper is to propose a new localized imaging method of reduced imaging time luting a locally-linear gradient. Since most fast MR(Magnetic Resonance) imaging methods need the whole $\kappa$-space(Spatial frequency space) data corresponding to the whole imaging area, there are limitstions in reducing the minimum imaging time. The imaging method proposed in this paper uses a specially-made gradient coil generating a local ramp-shape field and uniform field outside of the imaging areal Conventional imaging sequences can be used without any RF/gradient pulse sequence modifiestions except the change in the number of encoding steps and the field of view.

Presented is the study on design and implementation of a fuzzy system to approximately reason using measured actual storage rate in irrigation reservoirs. To design Fuzzy reasoning systems. Minimum Operation Rule by Mamdani was applied. Fuzzy variable and membership functions are determined after identifying storage-rate affecting factor and followed simulation. Hydrological model to express actual situation within drought areal boundary is generally too complex. Hereby, considering irregularity of time-rate storage change during irrigation, this system uses irrigation water and meteorological data as a IN-data. It was abvious the results were closely corresponding to the actual data observed.

Hospital Architectures in Korea are continuously erected to old-fashioned design, such as a large self-sufficient, but cost-inefficient hospital, in spite of rapidly changing social and healthcare environment. However, changes are slowly coming from inside of itself. This paper analyzed block plans of 7 best Korean hospitals which constructed in recent 20 years in aspects of the purpose of erection, departmental composition, areal composition, mass design and functional zoning of block plans and then, presented the directions of new design trends of hospital architecture in Korea. It is anticipated that hospital architecture will change immensely in the enlarging process of these minor changes.

This study was conducted to analyzed the pattern of $CO_2$ concentration changes in various time scale within and across the Korean Peninsula. We compared that data sets obtained from Moo-Ahn(NAN) station in Korea with those determined from major background observatory stations around the world from the periods of Aug. 1995 to Dec. 1997. The mean $CO_2$concentrations of the MAN area, if computed using the total of 884 daily mean values, were computed to by 374.5$\pm$6.6 ppm. When the background data for MAN were compared with those of other background site, the concentration of MAN was systematically higher than any other comparable sites. Results of correlation analysis between MAN and other background sites generally showed up the existence of strong correlations, indicating that the relative effect of $CO_2$ concentration change can proceed similarly over the globe. However, notable differences in annual growth rate of $CO_2$ between MAN and all the comparative sites suggested that its concentration in th MAN area be regulated in more complicated manners than those in the other areas. It is thus suspected that the data collected form MAN area be not effective enough to represent areal distribution characteristics of $CO_2$in the Korean Peninsula.

Today, because human settlements are concentrated into urban area, urban planning and management technique considering the complexity, diversity, and advanced situations of urban living space is being requested. Especially, to effectively respond to large and diverse climate change driven disaster, it is necessary to develop urban planning technique including land use, infrastructure planning based on disaster vulnerability analysis. However, because current urban climate change disaster vulnerability analysis system(UC-VAS) is using census output area as spatial analysis unit, it is difficult to utilize the analysis results for specific urban planning. Instead, this study applies the grid manner to two study areas. The analysis results show that it can generate more detailed results and it can be used for detailed zoning decision by comparing with areal photos. Furthermore, by describing the limitation of the grid manner and providing professional way to secure additional scientific character and objectivity of the future urban climate change disaster vulnerability analysis system, it is expected that this study contributes to the effectiveness of system management.

Seasonal biomass and carbon, nitrogen contents change of marsh club-rush (Schoenoplectus trigueter) was investigated in Nakdong river estuary, located near Busan, Korea. New shoot of S. trigueter sprouted from tuber in April and fast growth season was followed until mature in August. Mature lengths of shoot and root were 60 and 9.4 cm, respectively. The increase of biomass showed similar seasonal trends with length. Mature biomass were $3.5gind^{-1}$ in wet weight and $0.6gind^{-1}$ in dry weight. The biomass of S. trigueter in areal basis was also highest during July and August ($186gDWm^{-2}$). The shoot of S. trigueter was disappeared in October from the ground but the biomass of shoot was maintained as a form of detritus in sediment. The amount of S. trigueter detritus was about 30~50% of the biomass in August. During winter, the amount of detritus decreased with time but the biomass of root+tuber remained same, implying the root+tuber part is alive. The net productivity of S. trigueter estimated from biomass change were $538gDWm^{-2}yr^{-1}$, $240g-Cm^{-2}yr^{-1}$, $8.2g-Nm^{-2}yr^{-1}$ in dry weight, carbon and nitrogen equivalent respectively. During winter, carbon to nitrogen ratio in detritus increased implying the preferred remineralization of nitrogen during microbial degradation.

Coastal lagoon has experienced a natural geomorphic development process which has been aggraded after the climax of transgression in Holocene. This study estimates superiority on landscape conservation of lagoons and degree of landscape changes during the 20th century as conservation ratios of area and shore length, and analyzes the causes of the changes and classifies the lagoons based on the data by case study of the major 7 coastal lagoons(Hwajinpo, Songjiho, Gwangpoho, Yeongrangho, Maeho, Hyangho, and Gyeongpoho) in the middle East Coast of the Korean Peninsular. Based on the conservation ratios of area and shore length, the areal change is in order of Songjiho($0.56km^2$, 92%), Hwajinpo($2.06km^2$, 90%), Yeongrangho($0.96km^2$, 86%), Hyangho($0.32km^2$, 76%), Gyeongpoho($0.90km^2$, 52%), Maeho($0.14km^2$, 50%), and Gwangpoho($0.07km^2$, 32%), and the shore length change is in order of Hwajinpo(11.90km, 100%), Hyangho(3.34km, 90%), Yeongnangho(7.21km, 89%), Gyeongpoho(7.11km, 79%), Songjiho(5.56km, 79%), Gwangpoho(1.16km, 62%), and Maeho(2.16km, 58%). Therefore, the characteristics of landscape changes of the lagoons in the study area can be represented in order of Hwajinpo(Al), Hyangho(A2), Yeongrangho(A3), Songjiho(A4), Gyeongpoho(B4), Gwangpoho(B5), Maeho(B6). Serious process for land use and industrial development has changed landscape around lagoons decreasing the area of coastal plains dramatically up to this century. Because small lagoons such as Maeho and Gwangpoho have experienced severe transformation and destruction, and Gyeongpoho was transformed into artificial lake for urbanization and tourism, they show dramatic landscape change.

The result of the line simplification algorithm varies with the choice of algorithms, the change in tolerance and the selection of target objects. Three of the algorithms used in this study are Sleeve-fitting, Visvalingam-Whyatt, and Bend-simplify. They were applied to the three kinds of objects which were buildings, rivers, and roads with the five degrees of the tolerance. Through this experiments the vector displacement, the areal displacement, and the angular displacement were measured and the qualitative analysis was performed with the trend line of the errors. The experimental results show that errors were differ from tolerance values, and characteristics of line simplification algorithms based on changes of tolerance were understood.
