<P>Concern about energy-efficient medium access control (MAC) protocols for wearable devices is increasing owing to support for healthcare services using wireless body sensor networks (WBSNs). The most popular energy-efficient MAC protocol for WBSNs is the IEEE 802.15.6 standard, which adopts carrier sensing multiple access with collision avoidance (CSMA/CA). The CSMA/CA mechanism of the IEEE 802.15.6 standard allows differentiated channel access by assigning a different size of contention window to the nodes, each of which has a different priority. However, the existing CSMA/CA of IEEE 802.15.6 still cannot guarantee successful data transmission in error-prone channels and congested network environments, which leads to wasted energy owing to data retransmission. In this paper, we propose an adaptive priority-based MAC (AP-MAC) protocol for IEEE 802.15.6 WBSNs, which utilizes transmission opportunities suitable for WBSNs. For this, data types are classified with predefined priorities with each data type having a different opportunity to access the channel. In addition, the priority of each classification is updated adaptively according to the update metrics channel state and congestion level. Simulation results show the enhanced performance of the AP-MAC protocol compared with that of the IEEE 802.15.6 standard.</P>

본 연구는 개정된 10대 원칙전문을 입수하여 개정 전과 후 내용을 비교분석하고 북한 당국이 이를 북한 주민들에게 어떠한 방식으로 사상교양 사업을 전개하는지 살펴본다. 본 연구는 개정된 10대 원칙 전문을 입수하여 개정 전과 후 내용을 비교분석하고 북한 당국이 이를 북한 주민들에게 어떠한 방식으로 사상교양 사업을 전개하는지 살펴본다. 첫째, 김일성과 함께 김정일의 신격화를 진행한 점 둘째, 사회주의 체제 및 제도에 관하여 명료하게 정리하였으며 셋째, ‘구 10대 원칙’에서의 ‘교시집행의 준수’가 ‘신 10대 원칙’에서는 ‘유훈관철’로 변경되었고, 넷째, ‘신 10대 원칙’을 통해 혈통을 통한 통치정권계승의 당위성을 부여하였다. 아울러 북한 당국의 위로부터의 일방적 사상통제가 과연 북한주민들에게는 어떠한 인식기제로 작용하는지 알아보기 위해 북한 내부 협력자와의 전화통화녹취자료 및 10대 원칙 학습 동영상 자료를 분석한다. The purpose of this paper is to analyze North Korea’s “Ten Principles of the Monolithic Guidance System“ by comparing its transformation before and after the revision in 2013. Specifically, the study examines how Pyongyang’s ruling elite has employed ideological education through a literature survey of North Korea’s official newspaper, motion pictures learning materials on the ‘New Ten Principles,’ and data telephone logs. The survey demonstrates that North Korean ideological work since the 2013 revision has been marked by: first, intensified deification of Kim Il Sung and Kim Jong Il; second, elimination of reference to communism; third, emphasis on following the teachings of Kim Il Sung and Kim Jong Il within the ``New Ten Principles,``; and fourth, glorification of hereditary succession.

Sebum is an important component of the skin that has attracted attention in many fields, including dermatology and cosmetics. Pore expansion due to sebum on the skin can lead to various problems. Therefore, it is necessary to analyze the morphologicalcharacteristics of sebum. In this study, we used optical coherence tomography (OCT) to evaluate facial sebum areas. Weobtained the OCT maximum amplitude projection (MAP) image and a cross-sectional image of skin pores in the facial area. Subsequently, we detected the sebum in skin pores using the detection algorithm of the ImageJ software to quantitativelydetermine the size of randomly selected pores in the proposed MAP images. Additionally, the pore size was analyzed byacquiring images before and after facial sebum extraction. According to our research, facial sebum can be morphologicallydescribed using the OCT system. Since OCT imaging enables specific analysis of skin parameters, including pores andsebum, skin analysis employing OCT could be an effective method for further research.

This paper suggests a localization system architecture of unmanned vehicle for autonomous driving. In this system, Graph SLAM algorithm is used for correction of accumulated errors acquired from scan matching algorithm. On this paper, the experiments are proceeded in environment of mountainous city which have continuous elevations. The acceleration and magnetic data from IMU, RTK corrected GNSS are used for graph optimization and loop closure on mapping. NDT scan matching algorithm is used for localization.

Background and Objectives: In Kawasaki disease (KD), high dose intravenous immunoglobulin (IVIG) significantly lowers the coronary complications. However, some patients either do not respond to initial therapy or develop coronary complications. We aimed to identify the predictive factors for unresponsiveness to initial IVIG therapy and coronary artery dilatation (CAD; defined by Z-score≥2.5) in the acute phase and convalescent phase. Subjects and Methods: A retrospective review was conducted of 703 patients with KD, admitted to Gachon University Gil Medical Center between January 2005 and June 2013. The patients were divided into two groups—IVIG responders vs. non-responders—based on the IVIG treatments, and presence of fever after treatment. Further, these groups were divided into two subgroups based on their CAD. Results: Among the 703 patients with KD, the rate of non-responders to initial IVIG was 16.8%. Serum total bilirubin, platelet count, and neutrophil proportion were independent predictive parameters of unresponsiveness (p<0.05). CAD was found in 234 patients (33.3%) in the acute phase, and in 32 patients (4.6%) in the convalescent phase. Male gender, fever duration, serum C-reactive protein, and white blood cell count were related to CAD (p<0.05). CAD was detected more frequently in non-responders than in the responders (47.5% vs. 31.5%, p=0.001). Kobayashi, Egami, and Sano scoring systems applied to our study population reflected low sensitivities (28.0-33.9%). Conclusion: Several independent parameters were related to unresponsiveness to the initial IVIG or CAD. These parameters might be helpful in establishing more focused and careful monitoring of high-risk KD patients in Korea.
