The present study investigated the actual conditions of physical therapy rooms at long-term hospitals in Korea and conducted a comparative analysis to develop an efficient floor plan and facility improvement measures. 1. At hospitals surveyed, physical therapy services were used at a high frequency but they did not have enough space for rehab treatment and long paths of patient flow were found to make patient management inconvenient. Therefore, physical therapy units should be conveniently located both in terms of distance and direction so as to be accessible from patient rooms or wards. The space should be organized in a concentrated layout for efficiency of physical therapy, and floor planning for therapy units should ensure the best possible viewing angle to therapists. 2. With regard to the disease characteristics of patients, many physical therapy rooms were in difficult circumstances because of poor facilities, so they need to secure skilled personnel, supplement apparatuses and equipment and have rooms for functional recovery, hydrotherapy and operation treatment. In addition, each of the curtained or partitioned areas for treatment should be set up with consideration for the amount of space taken up by medical equipment. The area under each bed should be designed for patient convenience so that it can be used as storage space for patient's belongings and shoes. 3. Patients complained about the lack of physical therapy space, resting places or exercise areas and demanded the expansion of rehab programs and facilities. Physical therapy facilities need to be improved for patient privacy and effective natural ventilation. 4. At most of the long-term hospitals surveyed, physical therapy units were found to have small areas and treatment equipment and devices were insufficient compared to the number of patients. Therefore, it is required to secure more space (at least 138.24 sq. meters per 100 beds) and improve facilities for better physical therapy services.

Biodegradation of vanous medium-chain-length polyhydroxyalkanoates (MCL-PHAs) by an extracellular depolymerase system from Pseudomonas sp. RY-1 was investigated under laboratoly conditions. The degradation rate of the polymers was determined by quantitative clem zone technique, enzyme (turbidity) assay, and respirometry assay. Although the enzyme system secreted by Pscudomor~as sp. RY-1 was capable of degrading all MCL-PHAs tested. its secretion was influenced by the availability of secondary carbon sources. The rate of enzymatic degradation of MCL-PHAs was dependent upou the monomeric composition of the polyesters and reduced as the chain lengths of the monomer m t s in the polyesters increased. MCL-PHAs containing C-even monomer units showed faster degradation rate than MCL-PHAs containing C-odd monomer units. Respiration rates of MCL-PHAs with C-even monomer uuts were also much faster than those of MCL-PHAs with C-odd monomer units. The degmdation rate of MCL-PHAs bearing unsaturated substituents was faster than that of mcl-PHAs without functional substituents, which is suggesting the correlation between the degradation rate and the crystallinity of MCL-PHAs.

Due to development of modern medical services and economics, people raised expectation and demand about medical services from previous disease treatment to comprehensive health care covering prevention and health care. Responses of each medical facility to these social needs and the evolution of concept of medicine rapidly occur. The health examination centers are being operated with the purpose of health examination and this trend is reflected on several aspects such as the size of the facilities, function and configuration of space in health examination centers. Thus, health examination centers consisting of various space systems appear, but this trend and interpretations are lacking. Therefore, the purpose of this study is to draw trends of system through analysis of types and its evolved space systematic analysis and establish it. Analysis targets were classified into small, medium and large groups by sizes based on number of space and a total of 12 health examination centers in four for each category were selected. As research methods, functional relationship of space was examined through analysis of type in which segmentalized type tools were applied in local units. The flow diagram was established based on direction turning point and was classified into sub-flow and main-flow in local units and the systems between local units were derived. Finally, the results of this study can be summarized as the following three results. 1) The space connection system of health examination center showed four systems such as circulation, independence, continuation, and network. 2) Local type indicators and global type indicators which were evolved more from limitation of type analysis tools in existing research were derived so that more systematic analysis could be made. 3) Network system is distributed approach system and space for each function is formed around public space.

Service-oriented computing systems have been issued by their properties of reducing software development time and effort by reusing functional service units. The reusability of services can effectively promote through loose coupling between services. But strong associations of object-oriented systems such as inheritance and aggregation create a rather tight coupling between objects. The component-based systems without inheritance and aggregation create a loose coupling between components. Thus components provide service realization at runtime using the functionality provided by their interfaces. Therefore legacy component-based systems need to have service-oriented computing concept in order to support functional service units efficiently. Also, conventional methods for service-oriented computing system have not suggested the clear classification of service layers, the clear service identification guideline introducing service layers and a service mapping method between serviceces of each layer. Therefore we suggest the service classification and the identification guideline of business view and implementation view introducing layers and propose a mapping between two views. That is, we research service layers, service identification, diversified service sizes and a service mapping method between services of each layer. This can be applied to legacy component-based system to extend to the service-oriented computing system.

Bifidobacterium longum subsp. longum BBMN68, isolated from centenarians in Guangxi, China, has been proved to be a promising probiotic strain for its health benefits. In this study, the biodistribution of this strain in the rat gut was first investigated using the quantitative realtime PCR assay and propidium monoazide. Strain-specific primers were originally designed based on the BBMN68 genome sequence. Healthy rats were orally inoculated with either a single dose of BBMN68 (10¹⁰ colony-forming units/kg), or with one dose per day for 7 days and bacterial concentrations were analyzed in detail from the intestinal contents and feces of four different gut locations, including stomach, small intestine, colon, and rectum. Results indicated that strain BBMN68 could overcome the rigors of passage through the upper gastrointestinal tract and transiently accumulate in the colon, even though survival in the stomach and small intestine was not high. A good level of BBMN8 could stay in vivo for 72 h following a 7-day oral administration, and a daily administration is suggested for a considerable and continuous population of BBMN68 to be maintained in the host intestine.

This study investigated the status of kitchen of units in elderly housing facilities and the housing needs of residents. Compared with a lot of comprehensive and alternative studies on elderly housing facilities until now, specialized studies of behavior of elderly housing life and detailed dimensional study have hardly made. Therefore we intend to examine the status of kitchen planning on representative elderly housing facilities in Korea. As the methods of this study, we executed a field study into 4 representative elderly housing facilities in Korea. We visited each 2 units out of the outstanding 4facilities and surveyed the total 8 kitchens. Then we analyzed the space planning and kitchen furniture design of them and the state of kitchen commodities, and measured the kitchen equipment. In addition, we executed interview about satisfaction, preference, use from the residents. As a result, we could find out that depending on whether residents were sewed with meal offered from the facilities or not, the pattern of usage and commodities were quite different. It is necessary to supply the simplest spaces just for preparing some refreshment and tea are suitable. And for the self-cooking residents, much larger cabinets and utility rooms are additionally needed. Safety and functional aspect were quite well designed. Washing machines are usually built-in the kitchen cabinets, and residents are satisfied with this arrangement. We hope that the supplementary study about old people habit and behavior will be a good data of kitchen planning for Korean-type elderly housing units of facilities.

This paper proposes a new minimal resource high-level synthesis algorithm for low power design automation. The proposed algorithm executes an efficient approach to minimize the power consumption of the functional units in a circuit during the high level synthesis. In this paper, we visit all control steps one by one to reduce the switching activity in CDFG. The register sharing algorithm determines the minimum register after the life time analysis of all variable. According to property of input signal for functional unit, the proposed method visits all control step one by one and determines the resource allocation with minimal power consumption at each control step in a greedy fashion. The effect of the proposed algorithm has been proved through various filter benchmark to adopt a new scheduling and allocation algorithm considering the low rover.

This paper proposes an efficient token flow design methodology for a decoder in the MPEG Reconfigurable Media Coding (RMC) framework. The MPEG RMC framework facilitates a decoder to be configured with a set of modules called functional units (FUs) that are connected by tokens. Such a modular design philosophy of the MPEG RMC framework enables the reusability and reconfigurability of FUs. One drawback of the MPEG RMC framework is that the decoder performance can be affected by increasing the token transmissions between FUs. The proposed method improves the design of the FU network in the RMC framework toward real-time decoder implementation. In the proposed method, the merging of FU, the separation of token flow, and the merging of token transactions are applied to minimize the token traffic between FUs. The experimental results of the MPEG-4 SP decoder show that the proposed method reduces the total decoding time by up to 77 percent compared to the design of the RMC simulation model.

The synthesis of copolymers containing thiophene and benzimidazole unit by Stille polymerization is reported. The polymers with many unsubstituted thiophene units in the backbone have been reported to show low solubility, which has been a problem for spin-coating for the device fabrication. In dihexyl-2H-benzimidazole, the sulfur at 2-position of BT unit was replaced with dialkyl substituted carbon, while keeping the 1,2-quinoid form, to improve the solubility of the polymers. The PL emission spectra of the PHBIT1, PHBIT2 and PHBIT3 in chloroform solutions show maximum peaks at 500~561 nm. In thin films, maximum peaks of the PHBITs appeared at 529, 562 and 569 nm, respectively. The EL emission maxima of the PHBIT1 and PHBIT2 appear at around 588 and 576 nm, respectively. The current density and maximum luminescence of the LED with the configuration of ITO/PEDOT/ PHBIT2/Ca/Al are 552 mA/$cm^2$ and 46 cd/$m^2$, respectively.
