The Korean government has a new system for charging patient care for patients in hospital, on hold for the present(9 / 1995) but to start implementation in certain areas of patient care next year. From the latter half of next year the Ministry of Health and Welfare would like to start demonstration projects for hospitals who want to start using DRGs for frequently seen medical diagnosis and for patients with a course that is predictable and for whom non-insurance costs are minimal : such as the patient who has a delivery, cesarean deliveries, cataract surgery, tonsillectomy or an appendectomy, and apply the DRG system of payment for hospital care for these patients. The purpose of this study was to establish a recording system to give effective home health care to postpartum women and their newborns. Recently the government announced a DRG system to apply to postpartum women for pilot purposes starting next year. This gives impetus to the need to develop home care records that will allow for systematic recording and provide continuity and consistency in care across all health professionals and with in-depth communication between the professions to assure high quality care. There has been a rise in medical costs and a shortage of patient bed space in hospitals, particularly since the introduction of national medical insurance. The study focused on developing client selection criteria, a primary assessment tool, progress notes and nursing diagnoses applicable to postpartum and newborn clients. Selection criteria for home health care, assessment tool content, nurses progress notes and diagnoses were developed through a review of the literature, advice from professionals who are expert in home health care and actual practice in the use of recording tools through workshops. The recommendations based on the research results are as follows : 1) Replication and application of these tools is needed to test the validity of the tools 2) In order to have systematic nursing records standardization of records has to be done after nurses have had experience using them. 3) Reliability and validity of the tools has to be established through applicability to actual care situation.

There is an increasing interest in and efforts for safe residential environment from crimes nationwide. Many cities are making efforts to create safe residential environment by enacting ordinances and guidances on safe design for preventing crimes and implementing demonstration projects. In line with the trends of the times toward 'improvement of living conditions' through urban regeneration, the importance of the Crime Prevention Through Environmental Design(CPTED) has recently emerged in the field of residential housing regeneration. Indeed, the CPTED is included as essential factor in the recent deteriorated residential area regeneration related projects. In this respect, the purpose of this study is to provide the basic data on the methodology of CPTED to be applied to the regeneration of deteriorated residential area in the future. To this end, this study selected three representative CPTED projects in Busan - 'Deokpo-dong Hope and Stepping Stone Village,' 'Chilsan-dong CPTED Happiness Village' and 'Sujeong-dong Crime Prevention and Safe Village' as objects of this study and then investigated and analyzed project contents, application of CPTED strategy, subjects who are implementing projects, and the time when they implement projects as the framework of my analysis. The findings from this study are as follows: First, the projects that were largely based on hardware should be improved by including software in the future. Second, the current Step 2 should expand into Step 3 Maintenance in applying CPTED strategy. Third, it is necessary to encourage exchange and cooperation between unit projects and subjects who are operating related projects.

Dipstick urinalysis is used as a routine test for a screening test of UTI (urinary tract infection) in primary practice because urine dipstick test is simple. The result of dipstick urinalysis brings medical professionals to make a microscopic examination and urine culture for exact UTI diagnosis, therefore it is emphasized on a role of screening test. The objective of this study was to the classification between UTI patients and normal subjects using hybrid neural network classifier with enhanced clustering performance in urine dipstick screening test. In order to propose a classifier, we made a hybrid neural network which combines with RBF layer, summation & normalization layer and L VQ artificial neural network layer. For the demonstration of proposed hybrid neural network, we compared proposed classifier with various artificial neural networks such as back-propagation, RBFNN and PNN method. As a result, classification performance of proposed classifier was able to classify 95.81% of the normal subjects and 83.87% of the UTI patients, total average 90.72% according to validation dataset. The proposed classifier confirms better performance than other classifiers. Therefore the application of such a proposed classifier expect to utilize telemedicine to classify between UTI patients and normal subjects in the future.

This paper presents design and simulation of wide band RF microswitch that uses electrostatic actuation for its operation. RF MEMS devices exhibit superior high frequency performance in comparison to conventional devices. Similar techniques that are used in Very Large Scale Integration (VLSI) can be employed to design and fabricate MEMS devices and traditional batch-processing methods can be used for its manufacturing. The proposed switch presents a novel design approach to handle reliability concerns in MEMS switches like dielectric charging effect, micro welding and stiction. The shape has been optimized at actuation voltage of 14-16 V. The switch has an improved restoring force of 20.8 μN. The design of the proposed switch is very elemental and primarily composed of electrostatic actuator, a bridge membrane and coplanar waveguide which are suspended over the substrate. The simple design of the switch makes it easy for fabrication. Typical insertion and isolation of the switch at 1 GHz is -0.03 dB and -71 dB and at 85 GHz it is -0.24 dB and -29.8 dB respectively. The isolation remains more than - 20 db even after 120 GHz. To our knowledge this is the first demonstration of a metal contact switch that shows such a high and sustained isolation and performance at W-band frequencies with an excellent figure-of merit (fc=1/2.pi.Ron.Cu =1,900 GHz). This figure of merit is significantly greater than electronic switching devices. The switch would find extensive application in wideband operations and areas where reliability is a major concern.

To provide rice products in substituted for wheat flour and wheat products in elementary school foodservice, the survey for nutritionist in elementary school was accomplished from November 3rd to 8th, 2012 in Gwangju and Jeonnam area, and obtained 83 and 95 copies from Gwangju and Jeonnam, respectively. Most nutritionists were graduated from universities and had careers longer than 15 years. The nutritionists (56.7%) had worked at the schools where food allergy students were enrolled. The consumption of wheat flours per one student per month was 677.8 g in Gwangju and 707.4 g in Jeonnam. Udon and Jajangmyeon were more popular wheat products. Nutritionist agreed positively that rice products instead of wheat products were possible to use for meal menu (73.5% in Gwangju and 61.1% in Jeonnam). The frequent use of rice products was tteokbokkitteok, because of students' preference. The rice bread and tteokguktteok were preferred significantly higher in Jeonnam than in Gwangju. The advantages of rice products which perceived by nutritionists were benefits for health, digestive easily, and high nutritious, but their disadvantages were hard-to-find and expensive. The nutritional values of rice and recipes for cooking rice products were required as educational program for increasing consumption of rice products. Demonstration for rice cooking methods was selected most popular program. The application of rice products for school foodservice was preferred to Jeonnam compared to Gwangju (p<0.001). As a consequence, the nutritionists working in elementary school in Gwangju and Jeonnam area have positive thought about using rice products in school foodservice, if educational program of school foodservice menu using rice products should be demonstrated them.

The effectiveness of in situ sediment capping as a technique for heavy metal risk mitigation in Hyeongsan River estuary, South Korea was studied. Sites in the estuary were found previously to show moderate to high levels of contamination of mercury, methylmercury and other heavy metals. A 400 m × 50 m section of the river was selected for a thin layer capping demonstration, where the total area was divided into 4 sections capped with different combinations of capping materials (zeolite, AC/zeolite, AC/sand, zeolite/sand). Pore water concentrations in the different sites were studied using diffusive gradient in thin film (DGT) probes. All capping amendments showed reduction in the pore water concentration of the different heavy metals with top 5 cm showing %reduction greater than 90% for some heavy metals. The relative maxima for the different metals were found to be translated to lower depths with addition of the caps. For two-layered cap with AC, order of placement should be considered since AC can easily be displaced due to its relatively low density. Investigation of methylmercury (MeHg) in the site showed that MeHg and %MeHg in pore water corresponds well with maxima for sulfide, Fe and Mn suggesting mercury methylation as probably coupled with sulfate, Fe and Mn reduction in sediments. Our results showed that thin-layer capping of active sorbents AC and zeolite, in combination with passive sand caps, are potential remediation strategy for sediments contaminated with heavy metals.

With the growing trends of communication- broadcasting convergence, a hybrid IPTV that supports both IP network-based on-demand media and terrestrial or cable-based broadcast media is gaining attraction. This paper proposes a rich media framework for hybrid IPTV with support of the latest H.264 codec. For this purpose, we design and implement a media component and a RIA run-time engine customized for TV with the hybrid media. The media component has been designed to provide a uniform and efficient application interface to the various playback methods for RF broadcast and IP-based stored or live media. For performance and portability, it exploits media stream abstraction, adaptive on-demand I-frame search, and automatic calculation of play duration. Based on the proposed media interface, we develop a RIA run-time prototype. It has been carefully designed to fully utilize the built-in graphic acceleration hardware for optimized rendering in the resource-constrained IPTV environments. Demonstration and experiment results validate the performance and usefulness of the developed framework. The framework is expected to be used effectively to support graphics and hybrid media in the applications of IPTV-based VOD, advertisement, and education.
