The purpose of this study is to understand various styles of Korean house living, up to the present, to identify apartment living as the main house living, and plan and propose the interior unit spaces for apartment house based on the analysis on living space. A survey study was conducted to deduce the traditional major life style and its changes along with favorable housing spaces. In conclusion, this study proposed the unit space planning requirements that satisfies the conceptual and interior elements for habitant's characteristics and preference according to major life style as follow; 1) As the Ahn-bang(master bed room) has been changed from traditional space concept, it is mainly used as private space for husband and wife, and its utilized period is mostly at night time, the back-arrangement of the Ahn-bang should be considered. 2) As the living room is central space in the apartment housing and has complex functions which is utilized as space for family gathering and guest reception similar to the Ahn-bang of the traditional house, it should secure more space and it is desirable to arrange the space as open type by combining the pathway area. 3) As for the kitchen/dining room, the kitchen should be isolated from external attraction and the space for storing and preparing traditional foods should also considered, and the dining room should be arranged as open type. This study also suggests that since the apartment housing must be an integrated environment for habitants which satisfy behavioral, physical and mental elements simultaneously, the unit housing space should be constantly analyzed in various ways to produce a housing space which meet both their changing major life style and the temporal environment.

The purpose of the study was to identify the potential buyers' consciousness of single-family housing to provide useful data to help future single-family housing supplies in Ulsan. The study selected residents in Ulsan, who were over twenty and had an interest in living in a single-family housing. A survey was conducted from September 11, 2008 to September 25, 2008. The sample consisted of 364 persons who are currently live in Ulsan metropolitan area. The results are as following. About two thirds of the sample had the desire to live in a single-family housing. Moving into a single-family housing had financial preparation as the greatest issue. When moving into a single-family housing, the convenience of the residential district was the greatest consideration, whether or not it is a green environment, pollution level, etc. The potential buyers valued environment-friendly features and also had a very strong desire to own their own house. Many of them wanted to design and build their own single-family housing within a budget of 100-200 million KRW. In terms of the location, there was a higher preference for the riverside or lakeside rural areas outside the city. In terms of size, the preference was less than $330m^2$, which includes $99-132m^2$ for residential. When considering a single-family housing the direction was the most important feature, along with eco-friendly and safer materials and equipments. When building the single-family housing the potential buyers considered the community spaces first with a preference for having three bedrooms and two bathrooms. For the exterior, they wanted a unique shape of roof and there were high preferences for brown and beige colors. In terms of housing complexes, the potential buyers preferred individual unit types over complexes. If they preferred housing complexes, they wanted the cluster form complex with about 10-30 units. The complex also required a park-like setting with a guard system, which shows that convenience and safety were the most important features. In terms of complex management, they considered environmental management as the most important feature. The potential buyers were willing to pay belw 200,000 KRW, which showed their desire to minimize financial burdens.

Opened a court in February 10, 2006, a rule of safety management of the diagnosis radiation system was promulgated for safety of the radiation worker, patients and patients' family members. The purpose of this rule is to minimize the risk of being exposed to radiation during the process of handling X-ray. For this reason, we manufactured shielding device of mobile X-ray unit collimator for diminution of skin dose. Shielding device is made to a thickness of Pb 0.375mm. For portable chest radiography, we measured skin dose 50cm from center ray to 200cm at intervals of 20cm by Unfors Xi detector. As a result, a rule of safety management of the diagnosis radiation system has been strengthened. But there are exceptions, such as ER, OR, ICU to this rule. So shielding device could contribute to protect unnecessary radiation exposure and improve nation's health.

As FFT(Fast Fourier Transform) processor is used in OFDM(Orthogonal Frequency Division Multiplesing) system. According to increase requirement about mobility and broadband, Research about low power and low area FFT processor is needed. So research concern in reduction of memory size and complex multiplier is in progress. Increasing points of FFT increase memory area of FFT processor. Specially, SRU(Signal Reordering Unit) has the most memory in FFT processor. In this paper, we propose a reduced method of memory size of SRU in FFT processor. SRU of 64, 1024 point FFT processor performed implementation by VerilogHDL coding and it verified by simulation. We select the APEX20KE family EP20k1000EPC672-3 device of Altera Corps. SRU implementation is performed by synthesis of Quartus Tool. The bits of data size decide by 24bits that is 12bits from real, imaginary number respectively. It is shown that, the proposed SRU of 64point and 1024point achieve more than 28%, 24% area reduction respectively.

The purpose of this study was to compare the characteristics of floor plan of $85m^2$-sized housing units with 2-bay and 3-bay and the residents' satisfaction with them. The subjects for analyzing floor plan were six floor plans of $85m^2$-sized housing units with 2-bay and nine floor plans of housing units with 3-bay in the new town, Hwamyeong-dong, in Busan. The floor plans were analyzed based on seven characteristics of floor plans such as the composition type of entrance core hall, the entrance arrangement, width and depth of the housing unit, size of each room, LDK arrangement, arrangement of family bathroom and private bathroom for husband and wife, and balcony arrangement. The subjects for grasping satisfaction with each housing unit were 400 residents of $85m^2$-sized housing units. A half of them lived in housing units with 2-bay and another half of them with 3-bay in the same area. They answered about the degree of satisfaction with the characteristics of each room and the preferred floor plan type if they move to the same size housing units through a questionnaire. The results were as follows; First, the floor plan with 3-bay had more diverse elements than one with 2-bay. Second, the residents who lived in 3-bay housing unit were younger, higher education, and higher income than the ones in 2-bay. Third, the residents who lived in $85m^2$-sized housing unit were more satisfied with and preferred to 3-bay housing units than 2-bay one.

Matrix metalloproteinases (MMPs) are a family of zinc-dependent proteases that degrade extracellular matrix and basement membrane. These enzymes are play important roles in tumor cell invasion and metastasis, as well as angiogenesis and other connective tissue diseases. In our screening program for inhibitors of MMP-2 from fungal metabolites, we have isolated novel non-peptidic inhibitors of MMPs, designated gelastatin A and B from the culture broth of Westerdykella multispora F50733. The structures of gelastatin A and B were determined to be 3-(5E-hexa-2E,4E-dienylidene-2-oxo-5,6-dihydro-2H-pyran-3yl)-propanoic acid and 3-(5Z-hexa-2E,4E-dienylidene-2-oxo-5,6-dihydro-2H-pyran-3yl)-propanoic acid, respectively. Gelastatin A and B exist as a mixture of two stereoisomers in a ratio of 2: 1. The 2: 1 mixture of gelastatin A and B inhibited activated MMP-2 and MMP-9 with an IC$\sub$50/ value of 0.63, 5.29 ${\mu}$M, respectively. They inhibited the invasion of B16F10 melanoma cells through basement membrane Matrigel with dose dependent.
