배경: 약물로 인한 Clostridium difficile-associated diarrhea (CDAD)는 널리 알려져 있으며 우리나라에서 항생제와 프로톤 펌프 억제제 소모량을 고려할 때 질환 치료과정에서의 CDAD 발생빈도 및 CDAD 유발 이전에 투여한 약물의 사용빈도와 CDAD의 치료방법을 조사할 필요성이 있다. 방법: 경상대학교 병원에서 2011년 1월부터 6월까지의 입원환자를 대상으로 대변 독소 검사에 의해 CDAD로 판명된 환자의 성별, 연령분포, 질환명, 입원병동, 재발률을 조사하였으며 CDAD 판명이전에 투여한 약제 및 CDAD 판명후 치료약제를 조사하였다. 결과: 연구기간 동안 CDAD 대변 독소 검사 의뢰된 환자수는 1,500명이었으며 CDAD 양성은 111명(9.3%)이었고, 재발은 29명(26.1%)이었다. CDAD를 주소로 입원한 환자는 17명 (15.3%)이었고, 나머지는 입원기간 중에 발생하였다. CDAD 양성인 환자의 연령대는 60대에서 32.4% (36/111명) 이었고, 내과병동에서 34.2%를 나타내었고, 재발률은 외과계 병동에서 41.4%로 가장 높게 나타났다. CDAD 환자의 17% (19/111명)은 항암제 투여 동안 발생하였으며 CDAD 발생 전 사용약물로는 세팔로스포린계 항생제가 162회로 가장 빈번하게 사용 되었으며, 히스타민2 수용체길항제 107회, 스테로이드 82회, 비 스테로이드 항염제 79회, 프로톤 펌프 억제제 77회, 하제 59회, 항암제가 33회 처방되었다. CDAD 치료약제로는 8종의 약제가 241회 처방 되었으며 metronidazole이 99회로 가장 빈번하게 사용되었고, vancomycin이 37회로 나타났다. 결론: 입원환자에 있어서 CDAD양성은 특히 고령의 암환자가 많아 항암제 투여 시에는 CDAD 발생에 주의해야 할것으로 보인다. CDAD의 치료약제로는 metronidazole이 vancomycin 보다 많이 사용되는 것으로 나타났다.

Renewable energy (RE) is essential to comprise sustainable societies, especially, in rural villages of developing countries. Furthermore, application of off-grid RE systems to health care can improve the quality of life. In this research, a RE-based vaccination supply management system was constructed to enlarge the cold-chain in developing countries for the safe storage and delivery of vaccines. The system was comprised of the construction of RE plants and development of vaccine carriers. RE plants were constructed and connected to health posts in local villages. The cooling mechanism of vaccine carriers was improved and monitoring devices were installed. The effect of the system on vaccine cold-chain was evaluated from the field test and topographical analysis in the southern village of Nepal. RE plants were normally operated for the vaccine refrigerator in the health post. The modified vaccine carriers had a longer operation time and better temperature control via monitoring and RE-based recharging functionality. The topographical analysis estimated that the system can cover larger region. The system prototype showed great potential regarding the possibility of a sustainable and enlarged cold-chain. Thus, RE-based vaccine supply management is expected to facilitate vaccine availability while minimizing waste in the supply chain.

After the SPDP in health centers, 19.4% of health centers increased doctors and 25.8% decreased pharmacists. 58.1% of health centers showed that number of medical treatments were decreased. 96.4%, 80.6% 80.6% 96.7% of health centers showed that number of prescriptions, total medical treatment expenses, amounts paid by the insureds and the expenses to purchase drugs, respectively, were decreased. More than fifty percent(54.2%) of health centers responded that the relative importance of health works increased compared to medical treatments after the SPDP, and number of patients decreased compared to those in before the SPDP. And there was a drastic reduction in number of prescriptions, total medical treatment expenses, amounts paid by insureds, the expenses to purchase drugs after the SPDP. Above fifty percent(57.6%) of officers at health center responded that the function of medical treatment should be reduced after the SPDP. Fields requested improvement in health centers were 'development of heath works contents'(62.4%), 'rearrangement of health center personnel'(51.6%), 'priority setting for health works'(48.4%), 'restructuring the organization'(36.2%), 'quality impro­vement for medical services'(32.1%), 'replaning the budgets'(23.1%) in order. And to better the image of health centers, health center officers replied that 'health information management'(60.7%), 'public relations for health center'(15.8%), 'kindness of health center officers'(15.3%) were necessary in order. Health center officers suggested that 'vaccination program', 'health promotion', 'maternal and children health', 'communicable disease management', 'community health planning' were relatively important works, in order, performed by health center after SPDP. In the future, medical services in health centers should be cut down with a momentum of the SPDP so that health centers might reestablish their functions and roles as public health organizations, but quality of medical services must be improved. Also health centers should pay attention to residents for improving health through 'vaccination program', 'health promotion', 'mother-children health', 'acute and chronic communicable disease management', 'community health planning', 'oral health', 'chronic degenerative disease management', etc. And there should be a differentiation of relative importance between health promotion services and medical treatment services by character of areas(metropolitan, city, county).

A high intensity focuses ultrasound (HIFU) is one of the emerging technologies in the biomedical field. The piezoelectric HIFU transducer is a device that utilizes the thermal energy generated by high ultrasound energy. Recently an operating frequency of the HIFU transducer is to expand above a 7 MHz. In this study, the acoustic pressures and temperature distributions in the tissue that generated by the HIFU transducer at 10 MHz were calculated with the finite element method. In addition, the pressure focusing characteristics of the device were analyzed. The geometrical variables are the piezomaterial thickness, lens shape, water height, and film thickness. The results shown that the acoustic pressure increased and saturated gradually when the height/radius (H_L/R_L) ratio of the lens increased. Moreover, the focal area was gradually decreases with H_L/R_L ratio of the lens. In case of the optimized HIFU transducer, the maximum pressure and temperature were analyzed about 19 MPa and 65℃ respectively. And the -3 dB focused distances in the axial and lateral direction are around 2.3 mm and 0.23 mm respectively.
