목적: 한국에서 알레르기 질환 치료를 위한 한방 치료뿐만 아니라 대체 요법이 많이 이용되고 있으며, 그 현황에 대하여 다기관 조사를 시행하였다. 방법: 10개의 대학병원 외래로 내원한 647명의 알레르기 환자를 대상으로 설문조사를 시행하였으며, 이 중 510명이 한방 이외의 대체 요법에 응답하였다. 이환되어 있는 알레르기 질환은 천식(50.0%), 알레르기 비염(36.0%), 아토피 피부염(36.0%), 그리고 두드러기(9.3%)였다. 각각 환자들에게 12 문항의 설문조사를 시행하였으며, 한방 이외의 대체 요법의 사용 빈도 및 종류, 대체 요법에 의지하게 된 이유, 비용, 그리고 치료효과에 대한 의견을 물어 보았다. 결과: 16.7%의 알레르기 환자에서 한방 이외의 다른 대체 요법을 받았으며, 평균 1.6종의 한방 이외의 대체 요법을 받았다. 가장 많이 의지하는 대체 요법은 민간 식이요법 (48.6%)이었고, 그 다음이 아로마 요법(23.8%), 지압(14.3%), 건강 호흡법(7.6%), 마인드 컨트롤(5.7%), 목욕요법(5.7%) 순이었다. 대체 요법을 받은 환자 중 마인드 컨트롤(50%), 식이요법(50%), 그리고 건강 호흡법(75%)의 경우 치료 효과가 만족스럽다는 응답이 높았으며, 목욕요법, 아로마 요법, 그리고 지압은 만족도가 각각 33.3%, 28.0%, 26.7%로 저조하였다. 대체 요법 사용자의 63.6%가 5회 미만의 대체 요법을 받았고, 91.8%가 1년 이내로 치료받았으며, 1인당 평균 연 37 만원을 지출하였다. 대체 요법을 선택한 가장 큰 이유는 체질이 개선될 수 있을까 해서(44.2%)였으며, 대체 요법이 몸에 부담이 없어서(31.4%), 면역기능이 강화되어서(22.9%) 순으로 나타났고, 15.7%는 양약치료가 도움이 되지 않아서 대체 요법을 선택하였다고 응답하였다. 결론: 한국에서 알레르기 환자의 상당수가 한방뿐만 아니라 여러 가지의 대체 요법을 사용하고 있음을 알 수 있었다. 대체 요법의 사용 빈도가 증가하고 그 종류가 다양함을 고려할 때, 의료진은 대체 요법의 현황에 대하여 정확히 인지하고 이에 대해 관심을 가지고 환자를 대하여야 하며 올바른 알레르기 질환 치료법에 대해 환자뿐만 아니라 의료인에게 교육하는 것이 필요하다. Background/Aims: The use of unproven complementary/alternative medicine (CAM) to treat allergies is popular in Korea. We conducted a multicenter survey of the current use of CAM other than herbal medication in Korean allergy patients. Methods: This study enrolled 510 adults with allergic diseases, including asthma, allergic rhinitis, atopic dermatitis, and chronic urticaria, from ten hospitals. They underwent a structured questionnaire interview and clinical assessment of the prevalence, motivation, costs, and subjective assessment of CAM. Results: Of the patients, 16.7% used at least one type of CAM to treat their allergic diseases. Common types of CAM were diet (48.6%), aroma therapy (23.8%), massage (14.3%), breathing exercises (7.6%), baths (5.7%), and mind control (5.7%). The therapeutic effects of CAM included improved in patients using mind control (50%), diet (50%), breathing exercises (75%), and baths (33.3%), but worse in patients using aroma therapy (28%), and massage (26.7%). About 36.4% of the patients used CAM more than four times per year, and the average cost per CAM user was 370,000 won/year. The main reason for trying CAM was `hope to improve my constitution`. Conclusions: CAM is used widely for treating allergic diseases in Korea. Detailed knowledge of CAM and patient education are important. Further studies of the clinical efficacy of CAM are needed.

Genetic Characterization of Haemagglutinin 1 Domain of Influenza B Viruses Isolated in Korea during $1988{\sim}1999$

Shin, Gu-Choul,Na, Byoung-Kuk,Lee, Joo-Yeon,Ahn, Jung-Bae,Park, Jong-Won,Lee, Jin-Soo,Kim, Jee-Hee,Kim, Woo-Joo,Kang, Chun The Korean Society for Microbiology 2003 Journal of Bacteriology and Virology Vol.33 No.4

Although Korean influenza virus isolates have been genetically associated with the vaccine strains of the corresponding year, influenza B viruses have prevailed almost every year in Korea during the past decades. We have 'analyzed the genetic characteristics and evolutionary patterns of the haemagglutinin (HA) 1 domains of influenza B viruses isolated during 1988-1999 using direct RT-PCR and sequencing. Phylogenetic analysis of influenza B viruses isolated in Korea indicated that antigenically and genetically distinguishable strains of the lineage II and lineage III variants had been cocirculated. Variants prevailed in early 1990s are represented in 1996/97 and 1998/99 and some different variants have been co circulated geographically and prevailed concurrently in Korea. All HA1s of Korean isolates have amino acid substitutions mainly in the region between position 124 and 310, which was previously proposed an immunodominant region. Insertion-deletion patterns of the HA gene revealed that Korean influenza B viruses were evolved from Lee40 with different manner between lineage II and III viruses. Lineage III viruses were also divided into two groups as conserved group and inserted group, in relation to Lee40. But lineage II viruses had evolved with directional pattern. Antigenic index proposed that influenza B isolates prevailed since 1996/97 seasons might had emerged from the antigenic variants of a Seo1697-like virus and that new variants might appear from the lineage II viruses resulting in persistent prevalence in Korea.

Effect of active airway warming with a heated-humidified breathing circuit on core body temperature in patients under general anesthesia: a systematic review and meta-analysis with trial sequential analysis

Lee Je Jin,Choi Geun Joo,Lee Won Jun,Choi Sang Bong,강현 대한마취통증의학회 2023 Korean Journal of Anesthesiology Vol.76 No.1

Background: The application of a heated-humidified breathing circuit (HHBC) may reduce respiratory heat loss during mechanical ventilation, but its effect in preventing intraoperative hypothermia is controversial. This study aimed to investigate the effectiveness of HHBC in maintaining the core temperature of patients receiving mechanical ventilation under general anesthesia.Methods: We searched MEDLINE, Embase, Cochrane library (CENTRAL), and Google Scholar to identify all randomized controlled trials (RCTs) up to February 2022 that compared the intraoperative core temperature in patients with heated humidifier (HH) and other circuit devices. The primary outcome was the intraoperative core temperature at the end of surgery. The weighted mean differences (WMDs) between the groups and their 95% CIs were calculated for each outcome. We performed a trial sequential analysis of the primary outcomes to assess whether our results were conclusive.Results: Eighteen RCTs with 993 patients were included in the analysis. A significantly higher core temperature was observed at the end of surgery in patients with HH than those with no device (WMD = 0.734, 95% CI [0.443, 1.025]) or heat and moisture exchanger (WMD = 0.368, 95% CI [0.118, 0.618]), but with substantial heterogeneity.Conclusions: Although HHBC did not absolutely prevent hypothermia, this meta-analysis suggests that it can be used as an effective supplemental device to maintain the intraoperative core temperature under general anesthesia. However, considering the substantial heterogeneity and limitations of this study, further well-designed studies are needed to clarify the effectiveness of HHBC.

Lee, Jung Hwan,Park, Boram,Joo, Jungnam,Kim, Young-Il,Kim, Chan Gyoo,Lee, Jong Yeul,Choi, Il Ju,Yoon, Hong Man,Eom, Bang Wool,Ryu, Keun Won,Kim, Young Woo,Cho, Soo-Jeong Grune & Stratton 2018 Journal of clinical oncology Vol.36 No._suppl4

<P> 16 </P><P> Background: Although excess body weight has been known to be an important risk factor for mortality from many cancers including colorectal, endometrial and breast cancers, the prognosis of gastric cancer (GC) in obese patients seems controversial. Methods: We aimed to evaluate the association between body mass index (BMI) and mortality in GC in a large cohort. A single institute cohort of 7,765 GC patients undergoing curative gastrectomy between October 2000 and June 2016 were categorized into 6 groups; underweight (< 18.5 kg/m2), normal (18.5 to < 23 kg/m2), overweight (23 to < 25 kg/m2), obese I (25 to < 28 kg/m2), obese II (28 to < 30 kg/m2), and severely obese (≥30 kg/m2). The hazard ratios (HRs) for overall survival and disease-specific survival were calculated using Cox proportional hazard model. Results: We identified 1,279 all-cause and 763 disease-specific deaths among 7,765 patients, and the median follow-up period was 83.05 months (range, 1.02-186.97 months). In multivariable analyses adjusted by age, sex, tumor stage, comorbidity and operation methods, preoperative BMI was associated with all-cause mortality in a nonlinear pattern. As compared with patients who were normal weight, underweight BMI showed increasing mortality risk (hazard ratio (HR), 1.42, 95% confidence interval (CI), 1.15-1.77). In contrast, patients who were overweight (HR, 0.84; 95% CI, 0.73-0.97), obese I (HR, 0.77; 95% CI, 0.66-0.90) and obese II (HR, 0.77; 95% CI, 0.59-1.01) had lower risk of mortality. disease-specific mortality also had a similar pattern to overall survival showing the lowest mortality in obese II group (HR, 0.59; 95% CI, 0.40-0.88). There was no significant difference in severely obese patients in both all-cause and disease-specific mortalities. In spline analyses illustrated by a bell-shaped curve, risk for all-cause mortality was the lowest in patients with 26.67 kg/m<SUP>2</SUP>. Conclusions: Preoperative overweight and obese patients (23 to < 30 kg/m2) had lower all-cause and disease-specific mortalities compared to those with normal weight in GC patients who underwent curative surgical resection. </P>

BACKGROUND: The repair of large bone defects remains a significant challenge in clinical practice and requires bone grafts or substitute materials. In this study, we developed a unique hybrid bone scaffold comprising a three dimensional (3D)-printed metal plate for weight bearing and a biodegradable polymer tube serving as bone conduit. We assessed the long-term effect of the hybrid bone scaffold in repairing radial bone defects in a beagle model. METHODS: Bone defects were created surgically on the radial bone of three beagle dogs and individually-tailored scaffolds were used for reconstruction with or without injection of autologous bone and decellularized extracellular matrix (dECM). The repaired tissue was evaluated by X-ray, micro-computed tomography, and histological observation 6 months after surgery. The functional integrity of hybrid bone scaffold-mediated reconstructions was assessed by gait analysis. RESULTS: In vivo analysisshowedthat the hybrid bone scaffolds maintained the physical space and bone conductivity around the defect.Newbonewasformedadjacent to the scaffolds. Addition of autologousboneanddECMin thepolymertubeimproved healing by enhancing bone induction and osteoconduction. Furthermore, the beagles’ gait appeared normal by 4 months. CONCLUSION: The future of bone healing and regeneration is closely related to advances in tissue engineering. Bone production using autologous bone and dECM loaded on 3D-printed hybrid bone scaffolds can successfully induce osteogenesis and provide mechanical force for functional bone regeneration, even in large bone defects.

Risk Factors for Intracranial Injury Caused by Falls at Home in Korea Using Data from the Emergency Department-based Injury In-depth Surveillance (2011–2018)

Won-il Na,Ju Ok Park,조규종,Eui Jung Lee,Soon-Joo Wang,박항아 대한의학회 2021 Journal of Korean medical science Vol.36 No.7

Background: Most unintentional injuries that occur at home are preventable. However, it may be difficult to sufficiently reduce the number of falls occurring at home by only identifying risk factors focused on specific age groups. Therefore, this study aimed to identify the risk factors (especially age and places where injuries occurred at home) for intracranial injury (ICI) caused by unintentional falls at home. Methods: Using the Emergency Department (ED)-Based Injury In-depth Surveillance, we analyzed the data of patients who visited the ED due to unintentional falls at home. Risk factors were identified using multivariable logistic regression according to age groups and interactions between place of injury occurrence and age groups, and sex and age groups were assessed. Results: In total, 232,124 patients were included in the analysis; older adults had a higher adjusted odds ratio (aOR) 14.05 (95% confidence interval [CI], 12.74–15.49) of ICI than infants. The corridor was associated with ICI in the male pediatric group (aOR, 2.71; 95% CI, 1.08–6.84) and the balcony with the female pediatric group (aOR, 2.04; 95% CI, 1.03–4.04). In the adult group, aOR of kitchen was 1.38 (95% CI, 1.02–1.88) in females and 0.56 (95% CI, 0.48–0.66) in males. Conclusion: In this study, we identified the risk factors of ICI caused by falls at home using ED-based injury surveillance data. The risk of ICI was different among places of occurrence in the home depending on the age groups and sex.

Application of reinforcement learning to fire suppression system of an autonomous ship in irregular waves

Lee, Eun-Joo,Ruy, Won-Sun,Seo, Jeonghwa The Society of Naval Architects of Korea 2020 International Journal of Naval Architecture and Oc Vol.12 No.-

In fire suppression, continuous delivery of water or foam to the fire source is essential. The present study concerns fire suppression in a ship under sea condition, by introducing reinforcement learning technique to aiming of fire extinguishing nozzle, which works in a ship compartment with six degrees of freedom movement by irregular waves. The physical modeling of the water jet and compartment motion was provided using Unity 3D engine. In the reinforcement learning, the change of the nozzle angle during the scenario was set as the action, while the reward is proportional to the ratio of the water particle delivered to the fire source area. The optimal control of nozzle aiming for continuous delivery of water jet could be derived. Various algorithms of reinforcement learning were tested to select the optimal one, the proximal policy optimization.
