Stop Discussing New Medical Specialty Boards

정지태 대한의학회 2018 Journal of Korean medical science Vol.33 No.26

The Korean society is rapidly aging and the health care needs for aged people are increasing. In this context, some physicians claim to establish new medical specialty board (MSB) for geriatric medical experts but also MSB for primary medical care specialists, clinical pharmacologists, and public health experts. In Korea, basic concept for the specialty board system is still under debates and the legal support for the system is poor. At present, doctors with MSBs in private sectors supply 92.4% of primary medical care but the National Health Care System requires more primary care physicians than specialists in Korea. Therefore, the government must invest in the education of doctors more to improve the public health care system. The proposal of the new MSB for geriatric medicine must be gradually developed according to the national long-term health plan, social needs, and national budget for the public benefit. Please stop discussing unprepared new MSBs.

What Factors Impact Consumer Perception of the Effectiveness of Health Information Sites? An Investigation of the Korean National Health Information Portal

정지태,Yoon-Seong Lee,조희숙,심민선,이훈재,정수미 대한의학회 2017 Journal of Korean medical science Vol.32 No.7

Lay public's concerns around health and health information are increasing. In response, governments and government agencies are establishing websites to address such concerns and improve health literacy by providing better access to validated health information. Since 2011, the Korean government has constructed the National Health Information Portal (NHIP) website run in collaboration with the Korean Academy of Medical Sciences (KAMS). This study therefore aimed to 1) examine consumer use of NHIP, with respect to the usage patterns, evaluation on health information provided, and perceived effectiveness of the site; and 2) identify factors that may impact perceived effectiveness of the site. An online survey was conducted with 164 NHIP users, recruited through a popup window on the main screen of the portal website from October to November 2015. The significant predicting factors supported by the data include the relevance of health information on the site, the usefulness of information in making health decisions, and the effective visualization of information. These factors can inform future efforts to design more effective health information websites, possibly based on metadata systems, to further advance the lay public's information seeking and health literacy

간흡충증에 있어서 자기이동식 ELISA법을 이용한 혈청학적 진단에 관한 연구

Human clonorchiasis is one of the most common trematode diseases and of very important public health problems in Korea. Since skin test always represents neither current infection nor recovery of C. sinensis ova, the immunodiagnosis of human clonorchiasis is not always possible, a more feasible, simple, senstive and specific method is required. Several investigators have described the application of the enzyme-linked immunosorbent assay(ELISA) for the detection of Clonorchis antibodies as an additional serological technique for diagnosing clonorchiasis besides conventional tests. The ELISA method with polycarbonate-coated iron beads as the solid phase and with a magnetic transfer system (M-T ELISA) was proposed in the serodiagnosis of human clonorchiasis. Some of its advantages over the other ELISA systems have been reported as (ⅰ) the uniformity in the surface area of the solid phase involved in the reaction, which is important for the precision of the assay and (ⅱ) the simplicity and economy of simultaneous processing with such a semiautomated system. To investigate the feasibility and diagnostic accuracy of using the M-T ELISA in the sero-diagnosis of human clonorchiasis, sera tested were categorized into 134 clonorchiasis, 10 paragonimiasis, 63 non-infected human cases. To investigate the feasibility of using the standard ELISA with whole blood sample in the sere-diagnosis of clonorchiasis, 26 clonorchiasis subjects were studied. The standard ELISA and the M-T ELISA were performed with Veronal buffered saline antigen of C. sinensis, peroxidase conjugated anti-human IgG and orthophenylenediamine as a substrate by micro-method. The results obtained were as follows: 1. In the preliminary study each optimal dilutions of conjugate and serum by the M-T ELISA were 1/2,000 and 1/100 respectively. 2. The mean 0.D. (optical density) values in the sera of human clonorchiasis were 1.445 ± 0.445 by the standard ELISA and 0.943 ± 0.245 by the M-T ELISA. 3. The mean 0.D. values in the sera of non-infected human cases were 0.292 ± 0.127 by the standard ELISA and 0.308 ± 0.132 by the M-T ELISA. 4. If we proposed the 0.D. value 0.6 as a differential point of positive reaction, the sensitivity of the standard ELISA was 97.0% and of the M-T ELISA was 92.5%. And the specificity of the standard ELISA was 96.8% and of the M-T ELISA was 98.4%. 5. When the results were compared between the standard ELISA and the M-T ELISA of clonorchiasis sera showed that 91.0% gave same reactions. In the clonorchiasis, the O.D. values between the standard ELISA and the M-T ELISA methods were significant at a level of p<0.01. 6. When the results were compared between serum and whole blood sample by the standard ELISA showed same reactions in 95.1%. In the clonorchiasis, the 0.D. value between serum and whole blood sample were high significant at a level of P<0.01. The results between the standard ELISA and the M-T ELISA methods were no differences. So, these findings suggests that the M-T ELISA is more feasible and applicable in the sero-diagnosis of human clonorchiasis in field laboratories.

This study was undertaken to evaluate the status of intestinal protozoan infections in the children of specific groups. A total number of 441(male 250; female 191) consisting of 224 children of national feeble minded children institute, 59 Han-Bit blindness students, 158 children of local mental retardation children institute(Kang-Dong Ku) of specific groups were examined. The method employed was formalin-ether sedimentation technique with Lugol's iodine stain. The results were as follows: 1) The positive rates for any kinds of protozoan cysts were 13.8%(72 positives out of 441 samples) with sexual difference of 14.0% in male and 12.6% in female. 2) In the institute differences of positive rates of protozoan cysts were 15.2% in national feeble minded children institute, 16.9% in Han-Bit blindness school, and local mental retardation children institute(Kang-Dong Ku). 3) Cysts of Entamoeba coli were recovered in 8.6% and cysts of pathogenic amoeba, Entamoeba histolytica were found in 1.4%. Cysts of Endolimax nana (3.4%). Giardia lamblia (2.9%) were found in this study. 4) The degree of multiple infections of protozoan cysts were; single infection 81.4%, double infection 16.9% and quadriple infection 1.7% respectively.
