  • Background: In January 2018, revised elderly fixed outpatient copayment for the elderly were implemented. When people ages 65 years and older receive outpatient treatment at clinic-level medical institutions (clinic, dental clinic, Korean medicine clinic), with medical expenses exceeding 15,000 won but not exceeding 25,000 won, their copayment rates have decreased differentially from 30%. This study aimed to examine the changes of health utilization of elderly after revised elderly fixed outpatient copayment. Methods: We used Korea health panel data from 2016 to 2018. The time period is divided into before and after the revised elderly fixed outpatient copayment. We conducted Poisson segmented regression to estimate the changes in outpatient utilization and inpatient utilization and conducted segmented regression to estimate the changes in medical expenses. Results: Immediately after the revised policy, the number of clinic and Korean medicine outpatient visits of medical expenses under 15,000 won decreased. But the number of clinic outpatient visits in the range of 15,000 to 20,000 won and Korean medicine clinic in the range of 20,000 to 25,000 won increased. Copayment in outpatient temporarily decreased. The inpatient admission rates and total medical expenses temporarily decreased but increased again. Conclusion: We confirmed the temporary increase in outpatient utilization in the medical expense segment with reduced copayment rates. And a temporary decrease in medical expenses followed by an increase again. To reduce the burden of medical expense among elderly in the long run, efforts to establish chronic disease management policies aimed at preventing disease occurrence and deterioration in advance need to continue.

  • This study was conducted to investigate the status of pregnancy and delivery and relationship among knowledge, attitude and practice about pregnancy and delivery in poor country, Nepal. A questionnaire survey by interviewer was conducted to examine the general characteristics, knowledge about pregnancy and delivery, attitude about pregnancy and delivery, the rate of prenatal care and delivery condition of women who had an experience of delivery during last year$(1994.4.13\sim1995.4.12)$ at a rural area, nepal(Dolakha Bazar Area). The major findings are as follows ; Among respondents, 87.5 percentage never had health education and the degree of knowledge about pregnancy and delivery was low. Among respondents, 56.6 percentage had the attitude that they didn't want antenatal care, 42.8 % of respondents answered that they wouldn't visit hospital or health center when vaginal bleeding occurred and 82.9% thought that the delivery itself was dirty. The proportion of women who experienced antenatal care was 28.3%, the proportion of health facilities delivery was 5.3%, which was very low and 82.6% of home delivery case didn't sanitate the tool to cut the umbilical cord. The women who had positive attitude about antenatal care and health facility utilization experienced more antenatal care and health facilities delivery. On consideration of above findings, health education for pregnancy and delivery is required to improve mother-child health status in poor country. To make efficient health education, the target population group, such as the uneducated, inhabitants far from health center or medical facility, must be chosen. To help the poor countries in medical field, the study on health status and its related factors on these countries like this article would be required.

  • Although dental hygienists have performed chair-side assisting and other dental cares as well as preventive dental cares in Korea, medical technician law confines duties of dental hygienists as closed narrative. The aim of this study was to investigate difference in perception of duties of dental hygienists in dental clinic between dentists and dental hygiene students. A total of 245 copies of questionnaires were distributed to dentists and students by post-mail. Only 42 dentists and 30 students in an area replied these questionnaires about the present and future duties of dental hygienists after providing written consent. Both groups agreed that intra and extra oral X-ray taking, education about oral health behavior, instruction after dental treatment, chair-side assisting, consulting for patients, scaling, initial impression taking, management of dental materials and equipment, sterilization of equipment, and receiving dental bills are duties of dental hygienists. However, they had different perceptions about various dental treatments as duties of dental hygienists even if they were under instructions of a dentist, including infiltration anesthesia, filling in cavity, intramuscular injection, FC change, canal irrigation, orthodontic treatment including separating, ligature bracket bonding and removing, setting crown and bridge, making individual, removing implant screw, and so on. These findings demonstrated that there were different perceptions about duties of dental hygienists between dentists and dental hygiene students, especially on dental treatment.

  • This study was conducted to find out about the implementation status of dental treatment infection control standards of dental hygienists. The subjects of research were the dental hygienists working at dentist offices in Chungnam, Cheonan-si using self-input method from July 25th, 2012 to August 1st 2012. The collected data was analyzed after computerized statistical processing using SPSS 18.0. For hepatitis B vaccination, the results were high with 75.0% of answers being 'yes' or auto-active immunity, but for the latest hepatitis vaccination period showed highest results in '5 years or more ago' with 48.0%. Although 93.0% answered that vaccination was important, the percentage of replies that they had vaccination education was relatively low with 41.0%. For the use of personal protection tools the use of protective goggles was low compared to the use of masks and medical gloves. The percentage of subjects that answered that they always wash their hands before treatment was relatively low with 56.0% compared to 82.0% of subjects that answered that they always washed their hands after treatment. Dental treatment equipment washing before sterilization, use of packing and re-sterilization of tools with damaged packing showed high results for 'yes', but the ratio of subjects that answered 'no' to water line management was low with 39%.

  • 우리나라 대기오염의 수준은 지난 90년대 초반 이후 아황산가스와 총부유분진의 농도가 감소하고, 대신 오존과 이산화질소의 농도가 증가하면서 점차 다른 선진국에서 경험하는 대기오염현황을 보이고 있다. 한편 PM10과 PM2.5와 같은 미세분진의 경우 그 측정기간이 짧고 자료가 제한적이지만, 일부 지역에서 증가추세를 보이고 있으며, 그 수준을 비교하였을 때 현재 선진국에서 책정한 미세분진의 규제농도를 훨씬 상회하는 것으로 판단된다. 대기오염으로 인한 건강영향으로는 급성으로 고농도에 수 시간에서 수 일 동안 노출되는 경우 폐기능의 저하, 심박동의 변화, 그리고 신체내 염증물질의 증가 등 인체 기능의 변화가 보고되고 있으며, 기존에 폐장질환이나 심혈관질환을 앓고 있는 사람들의 경우 증세의 악화와 의료이용의 증가 등을 경험하거나 더 나아가 사망에 이르러 수명이 단축되는 것이 보고되고 있다. 급성노출의 경우 미세분진 PM10 10 $\mu$m/m3 당 전체 사망률이 0.5-1$\%$ 가량 증가하는 것으로 보고되며, 만성노출을 조사한 코호트 연구에 근거하는 경우 대기오염에 노출되는 전체 인구에 있어 PM2.5 1 $\mu$m/m3 당 1개월의 수명이 단축되는 것으로 추정되고 있다. 아직 대기오염으로 인한 건강영향의 기전이 전부 밝혀진 것은 아니지만, 일부 연구에서 대기오염물질 중에서 전이금속의 역할이 보고되고 있으며, 대기오염에 노출되면서 기관지, 폐포 및 혈액 등에서 염증매개물질의 분비 및 확산 그리고 심장을 비롯한 각 장기 기능의 변화가 보고되고 있다. 한편 이러한 변화들이 증세와 건강상의 비가역적 변화를 야기하는데 있어 대기오염 수준의 역치는 없는 것으로 판단되고 있다. 이러한 대기오염의 영향에 대한 개인수준의 해결책으로서는 자동차 사용의 절제 및 개인적인 쓰레기 소각의 자제 등 오염원 발생의 감소와 함께 대기오염 수준에 따른 증세 및 투약의 적절한 조절과 신체 활동의 조절을 통하여 오염원을 회피하는 것이 강조되어야 하며, 또한 흡연 특히 실내흡연의 금지와 실내 주방기구 및 난방기구의 관리 등이 구체적으로 제시될 수 있다. 마지막으로 대기오염물질들이 신체에 들어와 산화제로 작용하는 만큼, 식품을 통한 항산화제의 섭취가 일반적인 건강관리 수준에서라도 반드시 강조되어야 할 것이다.

  • In this study, a novel electromagnetic microrobot system with locomotion and drilling functions in threedimensional space was developed. Because of size limitations, the microrobot does not have actuator, battery, and controller. Therefore, an electromagnetic actuation (EMA) system was used to drive the robot. The proposed EMA system consists of three rectangular Helmholtz coil pairs in x-, y- and z-axes and a Maxwell coil pair in the z-axis. The magnetic field generated in the EMA coil system could be controlled by the input current of the EMA coil. Finally, through various experiments, the locomotion and drilling performances of the proposed EMA microrobot system were verified.

  • Purpose of this study was to compare the easiness of insertion of three Supraglottic airway devices(SADs) in a neutral and cervical neck collar position in a manikin setting. Three different SADs-Laryngeal Mask Classic (LMA), I-gel and Streamlined Liner of the Pharynx Airway(SLIPA) were applied. Thirty nine emergency medical technicians (EMTs) who are working in Korea 119 rescue services were taught briefly about the use of the LMA, I-gel and SLIPA in a manikin setting. The time to effective ventilation was shorter in I-gel ($10.5{\pm}2.2$, $11.4{\pm}5.7$) and SLIPA ($12.3 {\pm}5.1$, $12.0{\pm}6.8$) than LMA ($17.2{\pm}3.2$, $18.5{\pm}5.5$) in a neutral and cervical neck collar position, respectively(p<0.05). There was no difference between head positions in each of the airways. In conclusion, in the speed of insertion, I-gel and SLIPA were superior to LMA in the neutral and cervical collar setting of a manikin.

  • The purposes of this study were to develop a dynamic model of a human and to investigate the effect of a walker on an elderly subject's motions, such as sit-to-stand (STS) motion and normal gait, by using this model. A human model consisting of 15 segments and 14 joints was developed, embedded in $RecurDyn^{TM}$, and connected through a Simulink$^{(R)}$ interface with collected motion data. The model was validated by comparisons between joint kinematic results from inverse dynamics (Matlab$^{(R)}$-based in-house program) and from $RecurDyn^{TM}$ simulation during walking. The results indicate that the elderly walker induced a longer movement time in walking, such that the speed of joint flexion/extension was slower than that during a normal gait. The results showed that the muscle activities of parts of the ankle and hamstring were altered by use of the elderly walker. The technique used in this study could be very helpful in applications to biomechanical fields.

  • Corona-19, a disease caused by 'Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2)', was declared a global pandemic by the World Health Organization (WHO) in March 2020, and a real-time polymerase chain reaction test is performed as a diagnostic test for screening and confirmation in most countries. However, not only the target genes and protocols differ by countries, but also the procedures for reading the diagnosis results are diverse, so the criteria for confirmed patients differ by country. Therefore, in this review, we discussed the target genes, test techniques, and diagnostic criteria for each country notified by WHO. And the specificity and sensitivity, limits of detection, positive and negative controls, false positive bacteria candidates, and specimens, and the specifics of the control setting were also described. In addition, the characteristics of Korea's test were compared to each country's one. Finally, in order to obtain the same diagnosis result for SARS-CoV-2 in the future, standardized diagnosis methods and result interpretations for Corona-19 diagnosis were proposed.
