Background/Objectives: In this study, through big data analysis, the current situation and cause are identified and a plan to reduce accidents in bicycle accidents is derived. Methods/Statistical analysis: In order to secure data on bicycle traffic accidents, data from Gyeonggi-do were collected and analyzed using R and Tableau, which are big data analysis tools. After collecting the data, it was preprocessed according to the analysis. Findings: As a result of the analysis, it was found that bicycle accidents increased as the bicycle population increased. Therefore, in this study, an intersection notification and a bicycle cross-section were proposed. Improvements/Applications: The results of this study are expected to be used to develop policies that can be prevented in advance while instilling awareness of bicycle accidents.

저자들은 53세 여자로써 연하곤란, 철 결핍성 빈혈, 구각순증, 설염, 스푼형 조갑과 경부식도 막양구조를 특징으로 하고, 내시경적 풍선확장술에 의한 막양구조의 제거와 경구 철제 투여 후 현저한 증상의 호전을 보인 전형적인 Plummer-Vinson 증후군 환자를 경험하였다. 병력상 연하곤란이 나타나기 전부터 빈혈이 발견되었고, 철제 투여 후 피부와 점막의 병변도 호전된 점등을 고려해 볼 때 철 결핍이 본 질환의 발생에 중요한 역할을 한 것으로 추측할 수 있었다. Plummer-Vinson syndrome is a clinical entity characterized by dysphagia, iron deficiency anemia, cheilosis, glossitis, and cervical esophageal web, especially in middle aged women. Recently, the authors experienced a case of Plummer-Vinson syndrome. A 53-year-old female was admitted due to intermittent solid food dysphagia for 18 months. She had a 2 years history of iron deficiency anemia. On admission glossitis, fissures at the angle of the mouth, spoon nails, and iron deficiency anemia were noted. Esophagogram and esophagoscopic examination revealed thin walled concentric web at upper esophagus. Esophageal web was succefully teared by endoscopic balloon dilatation with subseguant improvement of dysphagia. Skin manifestations as well as anemia were markedly improved after oral iron replacement therapy.

Purpose: The concurrent regimen of docetaxel, doxorubicin, and cyclophosphamide (TAC) has been categorized as a high-risk factor for febrile neutropenia (FN). The incidence of FN was reported to be as high as 17%–26% in studies conducted in Western countries. However, these rates may vary among different ethnic groups. This study aimed to evaluate the incidence of FN and its effect on prognosis following adjuvant TAC chemotherapy in Korean patients with advanced breast cancer. Methods: We analyzed data from 187 patients who received 6 cycles of adjuvant TAC chemotherapy between July 2005 and December 2014. No patients received long-acting granulocyte-colony stimulating factor (G-CSF) as primary prophylaxis for FN due to guidelines for cost reimbursement in Korea. The incidence rates of FN, dose reduction of TAC, relative dose intensity (RDI), relapse-free survival (RFS), and overall survival (OS) were investigated. Results: A total of 102 (54.5%) patients experienced FN, especially older patients (51 years vs. 49 years, p=0.045). RDI was lower in patients with FN than in those without (96.4% vs. 99.5%, p=0.001, respectively). Death was reported in 2 patients (2.35%) without FN and in 10 patients (9.80%) with FN (hazard ratio [HR]: 6.64; 95% confidence interval [CI]: 1.28 to 34.36; p=0.024). No significant differences in RFS (p=0.235) were found using Kaplan-Meier analysis. Conclusion: The incidence of FN was significantly higher in Korea than in Western countries, and FN had a negative impact on the patients’ prognosis. Primary prophylactic G-CSF should be prioritized in Korean patients with advanced breast cancer who receive adjuvant TAC chemotherapy.

The purpose of this paper is to get the data required the preparation of comfortable building environment by measuring and analyzing Solid-Borne Sound in apartment building according to the source of sound and the position, as a basic step to understand and control the characteristic of the reduction of noises that occured in the building. For this experiment, we made use of the TIRE according to the standard rules of JIS as a impulse exciter, and the measurement was carried out after the building had all completed.

<P><B>Objectives</B></P><P>Fluoroquinolones (FQs) are the most important second-line drugs for MDR-TB treatment. Therapeutic options for FQ-resistant (FQ-R) MDR/XDR-TB are very limited. The purpose of the present study was to determine treatment outcomes and risk factors associated with unfavourable outcomes of MDR/XDR-TB, focusing on the impacts of FQ-R status and linezolid treatment.</P><P><B>Methods</B></P><P>This was a retrospective cohort study of 337 MDR-TB patients, including 144 (42.7%) FQ-R MDR/XDR-TB cases.

Overall, favourable outcomes were achieved in 272 (80.7%) patients. FQ-R second-line injectable drug-susceptible MDR [adjusted OR (aOR) 4.299, 95% CI 1.239–14.916, <I>P</I> = 0.015] and XDR status (aOR 6.294, 95% CI 1.204–32.909, <I>P</I> = 0.024) were independently associated with unfavourable outcomes. However, FQ-susceptible (FQ-S) second-line injectable drug-resistant MDR status was not associated with unfavourable outcomes (aOR 1.814, 95% CI 0.314–10.485, <I>P</I> = 0.999). Favourable treatment outcomes were more frequent in FQ-R MDR/XDR-TB patients who received linezolid (82.8%) compared with those who did not receive linezolid (58.1%, <I>P</I> = 0.002). When FQ-R MDR/XDR-TB treatment without linezolid was used as a reference, the addition of linezolid was associated with favourable outcomes (aOR 4.081, 95% CI 1.237–13.460, <I>P</I> = 0.017), comparable to those for FQ-S MDR-TB (aOR 4.341, 95% CI 1.470–12.822, <I>P</I> = 0.005).</P><P><B>Conclusions</B></P><P>Later-generation FQs could improve treatment outcomes of patients with MDR-TB. Linezolid should be considered for inclusion in FQ-R MDR/XDR-TB treatment regimens.</P>

환자의 긍정적인 예후에 있어 골든 타임을 최대한 확보하는 것은 중요한 요소로 손꼽힌다. 현재 응급의료 체계에서는 사고가 일어난 직후부터 응급 차량이 도착하기 전까지 응급구조요원이 환자의 상태를 파악 할 수 있는 방법은 제보자가 전달한 정보로 한정된다. 따라서 환자 상태의 수치적 측정의 부재 및 부족한 환자 정보는 골든 타임 확보에 있어 중요한 응급 처치를 결정하는데 큰 어려움을 야기한다. 이 같은 문제를 해결하기 위해 본 논문은 사고 직후부터 응급 차량이 도착하기 전까지 응급 구조 요원이 도착하기 전까지 환자의 생체 징후를 파악할 수 있도록 하여 적절한 응급 처치를 예측할 수 있도록 돕는다. 또한 환자 주변에 전문지식을 보유한 사람이 없는 경우에도 환자의 상태에 따른 최소한의 조치를 취할 수 있도록 도움을 줌으로써 응급 차량이 도착하기 전까지 환자가 최상의 상태를 유지할 수 있도록 한다.
