  • 본 논문에서는 IoT 기반의 스마트팩토리 구축을 위한 게이트웨이 프로토콜 아키텍처를 설계한다. 스마트 팩토리 시스템은 여러 단말 장치, 게이트웨이 및 서버로 구성되며 이들을 무선 네트워크로 연결한다. 단말 장치는 다양한 센서로부터 정보를 수집하고 게이트웨이를 통해 서버로 정보를 전송한다. 단말장치는 서버의 제어 알고리즘에 따라 또는 수동 조작으로 제어 신호를 수신하여 액추에이터를 제어한다. 따라서 게이트웨이 시스템은 무선 스마트 유틸리티 네트워크인 Wi-SUN과 인터넷을 연결하며 Wi-SUN의 코디네이터 역할을 하며 Modbus-TCP가 탑재되어 SCADA와 연동한다.

  • Purpose: This study investigated the immediate biomechanical effects of unilateral mastication for 10 minutes on the temporomandibular joint (TMJ) with 21 healthy adult participants. Methods: The gum group chewed gum on the right side for 10 minutes, and the control group rested for 10 minutes. Biomechanical data were obtained using a three-dimensional infrared camera before and after intervention. An independent t-test assessed the variation of kinematic data to identify differences between before and after intervention. Results: Among biomechanical variables, the gum group's length of the left forehead middle region and the temporomandibular joint angle decreased compared to the control group (p<0.05). Conclusion: Caution with unilateral masticatory activity is recommended, as unilateral mastication causes biomechanical changes due to excessive load on the soft tissues of the contralateral TMJ.

  • Background: Differentiating morphologic features based on hematoxylin-eosin (HE) staining is the most common method to classify pathological subtypes of non-small-cell lung cancer (NSCLC). However, its accuracy and inter-observer reproducibility in pathological diagnosis of poorly differentiated NSCLC remained to be improved. Materials and Methods: We attempted to explore the role of immunohistochemistry (IHC) staining in diagnosing pulmonary squamous cell carcinoma (SQCC) with poorly differentiated features by HE staining or with elevated serum adenocarcinoma-specific tumor markers (AD-TMs). We also compared the difference of epidermal growth factor receptor (EGFR) mutation rate between patients with confirmed SQCC and those with revised pathological subtype. Logistic regression analyses were used to test the association between different factors and diagnostic accuracy. Results: A total of 132 patients who met the eligible criteria and had adequate specimens for IHC confirmation were included. Pathological revised cases in poor differentiated subgroup, biopsy samples and high-level AD-TMs cases were more than those with high/moderate differentiation, surgical specimens and normal-level AD-TMs. Moreover, biopsy sample was a significant factor decreasing diagnostic accuracy of pathological subtype (OR, 4.037; 95% CI 1.446-11.267, p=0.008). Additionally, EGFR mutation rate was higher in patients with pathological diagnostic changes than those with confirmed SQCC (16.7% vs 4.4%, p=0.157). Conclusions: Diagnosis based on HE staining only might cause pathological misinterpretation in NSCLC patients with poor differentiation or high-level AD-TMs, especially those with biopsy samples. HE staining and IHC should be combined as pathological diagnostic standard. The occurrence of EGFR mutations in pulmonary SQCC might be overestimated.

  • 외인성 지방성 폐렴은 흔한 질환은 아니지만 동물성, 식물성 및 광물성 지방 물질이 원인이 될 수 있으며 발견된 예보다 훨씬 빈도가 많을 것으로 판단된다. 따라서 자세한 병력 청취로 원인 물질에 대한 노출을 우선 확인하여 지방성 폐렴을 의심하는 것이 선행되어야 한다.

  • Objective: To compare the efficacy of taxane-based regimens in the first line setting retrospectively in Chinese patients with recurrent and/or metastatic esophageal cancer. Methods: We analyzed 102 recurrent and/or metastatic esophageal cancer patients who received taxanes-based regimens in a first-line setting from January 2009 to December 2013. Sixteen (15.7%) patients were administered Nab-PTX based chemotherapy and 86 patients (84.3%) received paclitaxel (PTX) or docetaxel (DTX) based chemotherapy. Patients in the PTX/DTX group could be further divided into TP (71 patients) and TPF (15 patients) groups. Results: The objective response rate (ORR) of all patients was 20.6%, and the disease control rate (DCR) was 67.6%. The median overall survival (OS) was 10.5 months (95% CI 10.1-16.4) and the median progression-free survival (PFS) was 6.04 months (95% CI 5.09-7.91). The DCR was higher in the TPF group than the TP group (93.3% vs. 59.1%; p = 0.015 ). There were no significant differences in ORR, OS, and PFS among Nab-PTX, TPF and TP groups. Conclusions: The three regimens of Nab-PTX based, TP and TPF proved active in a first line setting of Chinese patients with recurrent and/or metastatic esophageal cancer, and should thus be regarded as alternative treatments.

  • 도시가 급성장함에 따라 보행자 가로가 잊혀져갔다. 하지만 성장이 안정됨에 따라 다시 보행자 가로가 중요시되고 있다. 동대문쇼핑센터 지역의 보행자가로에 현황을 조사 및 답사 결과 정비되지 않았으며 보행자의 안전이 보장되어있지 않았다. 따라서 동대문지역 보행자가로의 문제점을 도출하고 그에 따른 대안을 제시한다.
