Objective : To use and its affecting factors of patients' outpatient treatment that have single and multiple chronic illnesses Method : We used the 2011 study by the Ministry of Health and Welfare, "Report on Usage and Consumption of Korean Medicine." This report was conducted on outpatients and inpatients that visited Korean traditional medicine, from August 25th, 2011, to September 30th, 2011. Our research was based on 1729 patients with chronic diseases aged 30 and over who received outpatient treatment during the last three months. Results : There were 1365 patients with non-complex chronic diseases, while there were 364 patients with complex chronis diseases. Patients had 1 - 8 chronic diseases, and the average number (standard deviation) was 1.26 (0.59). There were statistically significant differences by sex(P<0.0001), age(p=0.0045), marriage (p=0.0060), education level(p<0.0001), income level(P=0.0063), and types of health insurance(p=0.0023). The diseases most common among patients with non-complex chronic diseases were: low back pain, arthritis, gastrointestinal disorder, frozen shoulder, side effects from motor accidents, high blood pressure, fracture, stroke, diabetes, cancer, atopic dermatitis, and asthma. The diseases most common among patients with non-complex chronic diseases were: arthritis+low back pain, low back pain+gastrointestinal disorder, low back pain+side effects from motor accidents, low back pain+frozen shoulder, arthritis+gastrointestinal disease, gastrointestinal disease+frozen shoulder, arthritis+low back pain+gastrointestinal disease, high blood pressure+arthritis, arthritis+low back pain+frozen shoulder, arthritis+fracture, and arthritis+side effects from motor accidents. There were statistically significant differences among the usage of medical clinics by: frequently used clinic (p<0.0001), number of treatment (p<0.0001), the cost of outpatient treatment (p=0.0073), the satisfaction rate (p=0.0171), whether the clinic is the preferred clinic (p=0.0040). In model 1, men than women, people who had local benefits instead of type 1 medical aid, and patients with complex chronic diseases were more likely to use Korean medical clinics. In model 2, men than women, people who had local benefits than people with types 1 and 2 medical aids, people who went to pharmacies and Korean medicine pharmacies than people who went to hospitals, people who went to get treatment 1-10 times than people who visited 11-20 times and more than 41 times, and people who spent less than ten thousand Korean won than people who spent 1 to 2 million Korean won, and people without complex chronic diseases were more likely to use Korean medical treatment. Conclusion : There were differences in sociodemographic characteristics and the usage of medical clinics between patients with non-complex chronic diseases and patients with complex chronic diseases. Among patients with complex chronic diseases, women, patients with types 1 and 2 medical aid, patients who used Korean medical clinics, patients who were treated 11-20 times and more than 41 times, and patients who spent 1 million to 2 million Korean won on outpatient treatment used less treatment than patients with non-complex chronic diseases. However, patients with complex chronic diseases used pharmacies and Korean medicine pharmacies more.

Objective : This study was intended to provide information pertaining to reasonable consumption of medical services based on comparative analysis of the characteristics of musculoskeletal diseases(MSDs) among outpatients of Korean medical institutes, and furthermore help lay groundwork for mapping out effective Korean medical policies. Method : Based on the data of 3,889 outpatients of Korean medical institutions which were obtained from the Ministry of Health and Welfare's 2011 Report on usage of Korean medicine, the analysis was carried out by using the SAS 9.2. Results : 68.2% of subjects were found to use Korean medicine(KM) for the treatment of MSDs. Patients with MSDs were older than those with nonmusculoskeletal diseases(NMSDs). And married state, education, employed state and incomes are effected on MSDs and NMSDs. Subjective health status, number of outpatient treatments, medical cost, medical treatment satisfaction, and habitue status are depend on MSDs or NMSDs. Acupuncture and physical therapy is Major treatments of subjects investigated to have the highest treatment effect. It was found that they had high degree of satisfaction with Korean medicinal outpatient treatments, and those with MSDs were found to have significantly greater satisfaction than those with NMSDs. Conclusion : Although aforesaid results suggest significant satisfaction with KM and high treatment effects for MSDs. Accordingly it is considered necessary to develop various services related to KM for treatment of MSDs and to plan for cost down of KM. Moreover, in-depth research into NMSDs is required for utilization growth of KM.

미세 회로 기판 제조에 적용되는 습식공정 중 도금조에서 미세 기판의 정밀한 가공을 위해 산성용액 반응조 내부의 유동특성을 관찰하는 것이 중요하다. 하지만, 상용 유속계 중 내산성을 갖춘 센서가 거의 없어 측정이 매우 어렵다. 본 연구에서는 내산성을 갖는 압저항 센서에 신호처리 기술을 적용하여 유속을 측정할 수 있는 센서를 개발하였다. 상용유속계 수준의 유속데이터 획득을 위해서는 높은 임피던스를 갖는 압저항 센서에 증폭회로 및 저역통과필터를 부착하였으며, 이 때 사용되는 신호처리회로의 출력과 상용유속계의 출력이 일치되도록 하는 신호처리회로의 선정을 위해 Butterworth, Bessel, Chebyshev 필터 회로를 제작하여 유속 측정을 통해 출력을 상용유속계의 출력과 비교한 결과 0.0128 %, 0.0023 %, 5.06 %의 MSE를 확인할 수 있었다. 인가 유속을 변경하면서 내산성 센서의 측정 가능 영역을 확인해 본 결과, 저속 저압 구간에서는 신호와 노이즈 구분이 어려워 신호 처리 알고리즘을 적용해도 원하는 결과를 얻지 못하였고, 2~6 ㎧에서 2.7 % 미만의 오차를 갖는 신뢰성 있는 측정이 가능하였다. This study presents the development of an acid resistance velocity sensor that is used for measuring velocity inside a copper sulfate plating bath. First, researchers investigated the acid resistance coating to confirm the suitability of the anti-acid sensor in a very corrosive environment. Then, researchers applied signal processing methods to reduce noise and amplify the signal. Next, researchers applied a pressure-resistive sensor with an operation amplifier (Op Amp) and low-pass filter with high impedance to match the output voltage of a commercial flowmeter. Lastly, this study compared three low-pass filters (Bessel, Butterworth and Chebyshev) to select the appropriate signal process circuit. The results show 0.0128, 0.0023, and 5.06% of the mean square error, respectively. The Butterworth filter yielded more precise results when compared to a commercial flowmeter. The acid resistive sensor is capable of measuring velocities ranging from 2 to 6 ㎧ with a 2.7% margin of error.
