NoSQL based Web Service System for Sharing of Emotion Information in Cloud Computing
Junho Jung,Jeong Byun,DongKeun Kim3 보안공학연구지원센터 2016 International Journal of Software Engineering and Vol.10 No.3
We present the No-SQL based Web service system for sharing of emotion information regarding the individual emotional states and location information of users using by a MongoDB in cloud computing environments. Pre-processed emotion information represents the individual emotional states categorized as a nine domain based on physiological signals recognition within the database system. However, in order to present individual emotional states regarding to pre-processed user’s emotional states and locations on a Web-based map, the computational overload with large amount of data for a location-query process is to be solved for support sharing Web services. Meanwhile, previous RDBMS-based systems are inadequate due to insufficient scalability and processing time of data processing nodes. Therefore, in this paper, we have designed and implemented an emotion sharing web service by reducing the load on the system using NoSQL database. In addition, it was confirmed that it is possible to effectively utilize resources and visualized by using Google’s FusionTable and it is possible to share on a Web map.
Primary cutaneous CD4+ small/medium T-cell lymphoma: a case report
Kim, Jeenam,Jeong, Minkyoung,Jun, Dongkeun,Lee, Myungchul,Shin, Donghyeok,Kim, Wookyoun,Choi, Hyungo Korean Cleft Palate-Craniofacial Association 2021 Archives of Craniofacial Surgery Vol.22 No.4
Primary cutaneous CD4+ small/medium T-cell lymphoproliferative disorder is a rare disease characterized by a single mass on the face or upper part of the trunk. It usually presents an asymptomatic and favorable progression, and its histopathologic findings include small and medium-sized lymphoid cells. The authors report a case of primary cutaneous CD4+ small/medium T-cell lymphoproliferative disorder on the forehead. A 51-year-old man presented with a protruding mass on his forehead that the patient had noted 1 month previously. Surgical excision and a permanent biopsy were performed under local anesthesia. Based on the biopsy results, the mass was diagnosed as a primary cutaneous CD4+ small/medium T-cell lymphoproliferative disorder. There was no evidence of recurrence at a 15-month follow-up visit.
단방향 지연 변이와 일주 지연을 이용한 양단간의 단방향 지연 추정

네트워크에서 QoS(Quality of Service) 제공 기술은 양단간 네트워크 경로의 안정성과 성능의 정도를 나타내는 QoS 척도에 대한 실제 측정에 기반을 두고 있다. QoS 척도 중에서 특히 단방향 지연의 측정은 양단간 두 측정 지점간의 클럭(clock) 동기가 선행되어야 한다. 하지만, 네트워크에서 모든 단말 또는 호스트(host) 사이에는 절대적 또는 상대적인 시간 차이가 존재한다. 본 논문에서는, 단방향 지연, 단방향 지연 변이와 일주 지연(round-trip time: RTT) 간의 관계식을 새롭게 유도하여, 추정 오류가 일주 지연의 사분의 일 이하가 됨을 수학적으로 보여주며, 이를 이용한 단방향 지연과 클럭 오프셋(offset)의 추정 기법을 제안하고 실험을 통하여 본 제안의 유용성을 보여준다. QoS-support technology in networks is based on measuring QoS metrics which reflect a magnitude of stability and performance. The one-way delay measurement of the QoS metrics especially requires a guarantee of clock synchronization between end-to-end hosts. However, the hosts in networks have a relative or absolute difference in clock time by reason of clock offsets, clock skews and clock adjustments. In this paper, we present a theorem, methods and simulation results of one-way delay and clock offset estimations between end-to-end hosts. The proposed theorem is a relationship between one-way delay, one-way delay variation and round-trip time. And we show that the estimation error is mathematically smaller than a quarter of round-trip time.

본 논문에서는 여러 산업의 전원계통에서 정전 및 순간정전 등의 사고로 발생할 수 있는 피해를 예방하는데 중요한 역할을 하고 있는 무정전전원공급장치(UPS: Uninterruptible Power Supply)의 인터넷 감시시스템에 대하여 기술한다. 별도의 네트워크 인터페이스장치를 설치할 필요가 없이 UPS를 인터넷에 직접 연결할 수 있도록 개발한 임베디드 시스템(Embedded System)의 하드웨어 구성과 다양한 네트워크 통신 프로토콜을 구현할 수 있도록 설계된 소프트웨어의 구성 및 특징을 설명하고, 인터넷에 연결된 UPS의 고장을 예방하거나 신속하게 처리할 수 있도록 개발하여 사용 중인 EMS(Ehwa Management Service)의 특징을 기술한다. 또한 EMS 서버를 이용하지 않고 간단하게 웹브라우저를 통해 감시할 수 있도록 Java 기술을 이용하여 구현한 웹감시프로그램에 대해서 기술한다.

This study describes about comparison of performance characteristics between Two-stroke Gasoline engine and LPG engine. The engines used in this study is the LPG engine and the gasoline engine that a single cylinder, diaphragm carburetor, two-stroke air-cooled SI engine for bursh cutter. In this study that we'd like to utilze for basic data that develop for fule or lubricating oil supply system of gasoline engine and LPG engine. The engine speed, power, torque, brake specific fuel consumption(BSFC) were measured and analyzed under the different throttle degree conditions respectively. The results showed that each of the rpm, touque, power with were increased at none-load condition and the excess air ratio tend to increasingly decreased accoding to engine speed. The BSFC that the gasoline engine and the LPG engine were showed the approximately 2000g/㎾h but the LPG engine was lowed at 6600rpm with effect to excess air ratio after lately increasing it
