대형병원의 의료 서비스 수준이 점차 높아지면서 이를 이용하려는 환자들이 늘어남에 따라 환자들이 받아야 할 진료의 대기 시간이 증가하여 병원 이용에 어려움을 겪고 있다. 따라서 진료 대기 시간을 단축하기 위하여 처방 전달 시스템, 진료 안내 시스템 등의 다양한 연구들이 진행 중이다. 그러나 기존에 제안되었던 연구들은 환자가 받아야 할 진료들의 상황을 고려하지 않고 순차적으로 진료 순서를 정하기 때문에 환자의 병원 이용 시간이 증가한다는 단점이 있다. 본 논문에서는 환자가 받아야 할 진료들의 예상 대기 시간과 평균 진료 시간을 더한 값인 예상 체재 시간이 가장 작은 진료를 추천하는 상황인지를 이용한 진료 안내 시스템을 제안한다. 상황인지를 이용한 진료 안내 시스템은 추천된 진료 순서를 바탕으로 환자의 스마트폰에 진료 정보 안내 서비스를 제공한다. 본 논문에서 제안한 상황인지를 이용한 진료 안내 시스템을 이용하면 환자가 병원에 머무는 시간이 최소화되며, 같은 시간 내에 최대한 많은 환자를 진찰할 수 있는 장점이 있다. 제안한 상황인지를 이용한 진료 안내 시스템과 기존 처방 전달 시스템의 성능 비교를 통하여 진료 순서 추천 방법의 우수함을 보인다.

In infants and small children, ultrasound (US) guidance provides ample anatomical information to perform neuraxial blocks. We can measure the distance from the skin to the epidural space in the US image and can refer to it during needle insertion. We may also visualize the needle or a catheter during real-time US-guided epidural catheterization. In cases where direct needle or catheter visualization is difficult, US allows predicting successful puncture and catheterization using surrogate markers, such as dura mater displacement, epidural space widening due to drug injection, or mass movement of the drug within the caudal space. Although many experienced anesthesiologists still prefer to use conventional techniques, prospective randomized controlled trials using US guidance are providing increasing evidence of its advantages. The use of US-guided regional block will gradually become widespread in infants and children.

Objectives: The purpose of the study is to investigate the parents' toothbrushing guidance on the children by operation of toothbrushing room. Methods: A self-reported questionnaire was completed by 790 parents of first, fourth, and sixth grade students of J elementary school in Changwon from June 1 to 30, 2013. J elementary school did not have toothbrushing room. The questionnaire consisted of general characteristics of the subjects (3 items), toothbrushing room operation (3 items), and toothbrushing (7 items). Data were analyzed using SPSS 20.0 program. Results: Parents of high school diploma demanded the establishment of toothbrushing room (p<0.05) and parents having undergraduate course tended to want the operation of toothbrushing room (p<0.05) and children's dental health care (p<0.05). Parents within forties tended to have higher concern for their children's toothbrushing (p<0.05) and toothbrushing room operation (p<0.05). They tried to have much interest in their dental health checkup and toothbrushing frequency. Conclusions: The establishment and operation of toothbrushing room is very important to elementary school children. The toothbrushing guidance by parents will enhance children's dental health knowledge and maintain lifelong dental healthcare for the children.

본 연구는 응급의료정보센터 직원의 직무인식 및 만족도를 조사하여 직원들의 직무만족을 향상시키고, 나아가 응급의료정보센터의 발전에 대한 긍정적인 제안을 위하여 조사되었다. 본 연구의 결과 직원들은 응급환자의 안내 및 상담업무를 가장 중요하고, 잘 수행하고 있다고 응답하였다. 또한 이송중인 응급환자에 대한 응급처치의 지도 및 이송병원의 안내 업무의 난이도가 높다고 조사되었다. 근무 시 업무에 대한 사명감과 직무 만족도는 보통 이상인 편이나, 전체적인 근무조건, 급여만족도는 만족하지 않게 나타났다. 환자 상담시 모두 스트레스를 느끼고 있었고, 특히 환자를 직접 볼 수 없는 상태에서 제한된 정보로 응급실 내원이나 지속관찰 등을 결정해야 하는 면과 근무인력부족에서 스트레스가 많았다. 또한 정보센터의 위상에 대해서는 정보센터의 정체성에 대해 문제가 크다고 생각하고 있었고, 그로 인해 행정기관과 응급의료기관, 119 구급대와의 응급처치지도, 이송정보 제공 및 병원안내와 같은 유기적인 업무 협조체계를 구축하는 것이 어렵다고 느끼고 있었다.

의료서비스 로봇은 연구자 및 정부 관계부처들을 통해 다양하게 정의 및 분류되고 있으나 수술로봇과 재활로봇은 공통적으로 의료서비스 로봇에 포함되며, 이를 제외한 로봇은 기타 의료서비스 로봇으로 분류되고 있다. 본 연구에서는 기타 의료서비스 로봇 중 물류, 안내, 약제처리 로봇을 중심으로 국내·외 개발동향 및 활용사례 등을 고찰하였다. 물류로봇과 안내로봇은 국내에서 상당수 제품으로 개발되어 병원 등에서 시범사업을 완료했거나 상용화가 진행 중이며 수출도 하고 있으나 약제처리 로봇은 국내에서 개발된 제품이 있음에도 불구하고 병원에서 활용 중인 제품은 수입품이었다. 물류, 안내 및 약제처리 로봇은 생산인구의 감소 및 코로나19로 인한 비대면 수요 증가 등에 대응하기에 비교적 상용화가 용이하고 비용 효과적인 로봇이나 이러한 로봇에 대한 수요 예측 연구 등을 찾아보기 어려우므로 시장 확대와 활성화를 위해 체계적인 추후 연구가 필요하다.

Radical trachelectomy is a fertility-preserving alternative to radical hysterectomy in carefully selected young women with early-stage cervical cancer. However, in cases with subsequent severe cervical stenosis, assisted reproductive techniques can be difficult. This is a case report of a 34-year-old patient who underwent robot-assisted radical trachelectomy and cerclage for early-stage (IB2) adenosquamous carcinoma. Three months after surgery, the patient underwent ovarian stimulation using a gonadotropin-releasing hormone antagonist protocol. As it was impossible to perform transcervical embryo transfer due to the almost complete absence of the cervical opening, transmyometrial embryo transfer under ultrasound guidance was performed. This resulted in a successful singleton pregnancy. This is the first case of successful pregnancy conceived by in vitro fertilization with transmyometrial embryo transfer in a patient who had previously undergone robot-assisted radical trachelectomy.

Objective: To evaluate the therapeutic outcomes of no-touch radiofrequency ablation (NT-RFA) using twin cooled wet (TCW) electrodes in patients experiencing recurrent hepatocellular carcinoma (HCC) after undergoing locoregional treatments. Materials and Methods: We conducted a prospective, single-arm study of NT-RFA involving 102 patients, with a total of 112 recurrent HCCs (each ≤ 3 cm). NT-RFA with TCW electrodes was implemented under the guidance of ultrasonography (US)-MR/CT fusion imaging. If NT-RFA application proved technically challenging, conversion to conventional tumor puncture RFA was permitted. The primary metric for evaluation was the mid-term cumulative incidence of local tumor progression (LTP) observed post-RFA. Cumulative LTP rates were estimated using the Kaplan-Meier method. Multivariable Cox proportional hazard regression was used to explore factors associated with LTP. Considering conversion cases from NT-RFA to conventional RFA, intention-to-treat (ITT; including all patients) and per-protocol (PP; including patients not requiring conversion to conventional RFA alone) analyses were performed. Results: Conversion from NT-RFA to conventional RFA was necessary for 24 (21.4%) out of 112 tumors. Successful treatment was noted in 111 (99.1%) out of them. No major complications were reported among the patients. According to ITT analysis, the estimated cumulative incidences of LTP were 1.9%, 6.0%, and 6.0% at 1, 2, and 3 years post-RFA, respectively. In PP analysis, the cumulative incidence of LTP was 0.0%, 1.3%, and 1.3% at 1, 2, and 3 years, respectively. The number of previous locoregional HCC treatments (adjusted hazard ratio [aHR], 1.265 per 1 treatment increase; P = 0.004), total bilirubin (aHR, 7.477 per 1 mg/dL increase; P = 0.012), and safety margin ≤ 5 mm (aHR, 9.029; P = 0.016) were independently associated with LTP in ITT analysis. Conclusion: NT-RFA using TCW electrodes is a safe and effective treatment for recurrent HCC, with 6.0% (ITT analysis) and 1.3% (PP analysis) cumulative incidence of LTP at 2 and 3-year follow-ups.

A 57-year-old male patient had myeloma. He had severe pain in the left clavicle that did not respond to radiotherapy; therefore, it was treated with radiofrequency thermal ablation (RFTA). Under fluoroscopic guidance, two RF needles at a distance of 1.5 cm from each other were inserted into the mass and conventional radiofrequency ($90^{\circ}C$ and 60 seconds) at two different depths (1 cm apart) was applied. Then, 2 ml of 0.5% ropivacaine along with triamcinolone 40 mg was injected in each needle. The visual analogue pain score (VAS from 0 to 10) was decreased from 8 to 0. In the next 3 months of follow-up, the patient was very satisfied with the procedure and the mass gradually became smaller. There were no complications. This study shows that RFTA could be a useful method for pain management in painful osteolytic myeloma lesions in the clavicle

Chemical mixtures of components, each of which are present at less than guidance concentrations, may be hazardous due to additivity, interactions, or both. Toxicological interactions may increase the health hazard above what would be expected from an assessment of each component singly, or all components additively. So chemical mixture are a particular issue in public health. There are several approach to assess whether there are additivity or interaction in assessing toxicological effects, such as, components-based approach, physiologically-based pharmacokinetic /pharmacodynamic(PBPK/PD) models, hazard index method, and weight-of evidence method. If we consider interaction or additivity effects in assessing the health effects of chemcial mixtures, we can get more accurate information about toxicological effects and dose-response relationship in chemical mixtures.
