To improve the corrosion resistance of stainless steel and Fe, the adherence between fIlm and substarte and the corrosion resistance to ceramic fIlm ($TiO_2$ and $ZrO_2$), coated by RF magnetron sputtering, were studied. The adherence index (X) was determined by the measure of micro - hardness test. Also, the corrosion resistance on oxide coatings was studied using electrochemical measurement. The main results obtained are as the following: 1) In the micro - hardness test, with 1J.UI1 thickness fIlm, it has only one the value of X. Above 2J.UI1 thickness fIlm, however, get another value ofX as the cracks in fIlm. 2) The adhensivity of titania ($TiO_2$) coated fIlm is superior to that of zirconia ($ZrO_2$) coated fIlm. 3) All oxide fIlm used adhere well on the mild materials such as pure steel than high intensity materials like stainless steel. 4) The corrosion resistance of zirconia coated materials was improved compared to titania coated materials.

There is a problem to be solved for improvement of durability and safety supervision. When you do the waterproofing work of main concrete from the design stage, the material and method of construction need to be correctly applied to appropriate circumstance conditions. Epoxy have mostly been used for concrete water tank structure. Lately, lots of subjects on adaption of polyurea resin waterproofing and anticorrosive are under discussion. Then, we attempt to approach by evaluating and comparing every capabilities with another waterproofs in this study. Performance evaluation items include the adherence performance, the imprint of seal performance, temperature dependence performance, promotion weatherizing ability, Inner chemical performance. drinking water eruptive performance. Through the experiment analysis, we found that the polyurea resin waterproofing membrane is dominantly superior to other waterproofs. According to this study, we suggest the polyurea resin waterproofing membrane as a new waterproofing material for concrete structure.

High temperature anneal of W-rich silicides, inferior to adherence compared with Si-rich silicides, resulted in the film peeling off from the Si-substrate when WSix thickness reached more than critical thickness. Investigation of the W-rich silicide films peeling off from the substrate revealed that the voids underneath the $WSi_2$ produced through silicide reaction were responsible for the poor adherence of W-rich silicide. In addition, internal stress in the film increased as the silicide thickness increased. In order to promote the adhesion of WSix to Si-substrate, thin Ti-layer was formed between WSi and Si-substrate(WSix/Ti/Si). No voids were observed in $WSi_2$/Ti/Si $N_2$-annealed at $1000^{\circ}C$, thereby leading to an increase of the critical thickness from ～1700$\AA$ to more than 2500$\AA$. However, higher resisiti-vity was obtained in WSix/Ti/Si than in WSix/Si. Finally, different silicide reaction mechanism for the structures(WSix/Si, WSix/Ti/Si) was proposed to explain the formation of voids as well as the role of thin Ti-layer.

Purpose: This study was to ascertain whether there are differences in health care utilization and expenditure for Type I Medical Aid Beneficiaries before and after applying Copayment. Methods: This study was one-group pretest posttest design study using secondary data analysis. Data for pretest group were collected from claims data of the Korea National Health Insurance Corporation and data for posttest group were collected through door to-door interviews using a structured questionnaire. A total of 1,364 subjects were sampled systematically from medical aid beneficiaries who had applied for copayment during the period from December 12, 2007 to September 25, 2008. Results: There was no negative effect of copayment on accessibility to medical services, medication adherence (p=.94), and quality of life (p=.25). Some of the subjects' health behaviors even increased preferably after applying for copayment including flu prevention (p<.001), health care examination (p=.035), and cancer screening (p=.002). However, significant suppressive effects of copayment were found on outpatient hospital visiting days (p<.001) and outpatient medical expenditure (p<.001). Conclusion: Copayment does not seem to be a great influencing factor on beneficiaries' accessibility to medical services and their health behavior even though it has suppressive effects on outpatients' use of health care.

Purpose: Medical Aid Beneficiaries were surveyed to identify differences in health behaviors, adherence to drug regimen, and quality of life between those people in the Designated Doctor System and those who are not. Methods: A total of 1,327 study subjects were separated into three groups: those in the Designated Doctor System for 2 years, those in for 1 year, and those not in the system. Results: After the introduction of the Designated Doctor System, 55.8% and 67.9%, respectively, of the subjects in the Designated Doctor System complained of inconvenience in relation to hospital use and the patient referral process. Also, the rate of emergency room use or hospitalization guided by the Designated Doctor System was only 8.7% and 6.5%, respectively. There were no significant differences in health behaviors and adherence to drug regimens between those in the Designated Doctor System and those who are not. Conclusion: This study was carried out early in the introduction of the system. Therefore, it is necessary to monitor the positive and negative effects of the Designated Doctor System for a full reflection of its impact.

As Korea is expected to enter an aging society in near future, the number of patients who need a long-term prescription is expected to increase as well. In particular, Korea shows the highest in both the incident rate and the death rate among OECD member nations. The current situation requires more strict monitoring and management for patients' taking medicine, there are a few practical problems such as personnel expenses. In order to realize the efficient management of medicine administration, this paper proposes a smart pillbox that is developed based on IT technologies. Through the experiments in which actual patients participate, it is proved that the smart pillbox is beneficial to the patients taking medicine.

The purpose of this study is to evaluate whether to take a medicine based on a measuring data using textile proximity sensor. We developed a proximity sensor of ring type using conductive textile, and acquired a data in accordance with the quantity of each pills. To evaluate our approach, we designed an experimental protocol that is counting pills subtracting the one which contains range of 0 T(Tablet, 4,100mg) from 20 T. And, The experiments were performed a nine times in the same way. In order to remove a noise and smoothen data, data preprocessing were performed using resampling method and moving average filter which has ten points. Then, we calculated a linear trend line equation, and analyzed a correlation between pill quantity and trend line equation. As a results, correlation coefficient was shown at 0.833 through using a Spearman's correlation method and we could be determined that data was continuos decreases when take a medicine.
