Objectives: The objective of this study is to develop a specialized clinical research protocol for acupuncture treatment specifically designed for disaster survivors based on insights from an expert survey. Methods: An expert panel comprising specialists in neuropsychiatry, acupuncture, and clinical research methodology was assembled. Initial data to inform the clinical research protocol design was collected utilizing open-ended responses, multiple-choice questions, and a 5-point Likert scale to gauge agreement levels. Next, this data was disseminated to a panel of experts. A cohesive clinical research protocol was then formulated during a core panel meeting by integrating insights from a panel of 10 experts. Results: The protocol developed herein entails a non-randomized controlled study involving participants aged 19~64 years old who have been identified as high-risk or cautious according to the National Trauma Center screening test. The study design includes the establishment of an active control group, which allows for the assessment of an additional effect through comparison with conventional therapy. The selected acupuncture approach involves a combination of manual acupuncture and ear acupuncture. For clinical outcome assessment, the Clinician-Administered Posttraumatic Stress Disorder Scale for DSM-5 was proposed to gauge trauma symptoms. Representative scales for various domains such as depression, anxiety, anger, insomnia, pain, and quality of life were also provided for reference. Conclusions: The developed protocol is anticipated to streamline the swift design and initiation of clinical trials during disaster scenarios. It is also designed to be scalable, thereby enabling its application in both non-randomized control group studies and single-group before-and-after comparisons.

Fire blight is a bacterial disease caused by Erwinia amylovora. In Korea, fire blight was first reported in 2015 in an orchard. If the infection is confirmed, all trees in the orchard must be removed and the orchard must remain closed for 3 years. Since 2020, if the number of trees infected with fire blight is less than 5% of the total trees in the orchard, only the infected tree and adjacent trees are removed in Korea. Three years after removal, the trees can be replanted after confirming that the orchard soil is free from E. amylovora. In this study, a protocol was established for detecting E. amylovora in soil via selective enrichment, using tryptic soy broth with 0.05% bile salts and 50 ㎍/ml cycloheximide, and real-time polymerase chain reaction. This protocol resulted in a 1,000-times improved detection limit for E. amylovora in soil samples compared to that in unenriched samples. Soil monitoring was performed for orchards where fire blight-infected trees had been removed 3-27 months prior; the selected orchards were monitored every 3 months. Monitoring confirmed that E. amylovora was not present in the soil at any site in any of the orchards. A new detection protocol facilitates the monitoring of E. amylovora in soil and could help permit the replanting of trees in orchards. Also monitoring results provide evidence that trees can be planted earlier.

In this paper, we design and implement the Wireless Transaction Protocol (WTP) proposed by the Wireless Application Protocol (WAP) forum using a protocol development tool, SDL Development Tool (SDT). And we conduct a comparative performance evaluation of the WTP implementation with other three implementations that are based on different implementation models respectively: the server model, the coroutine model, and the activity-thread model. To implement WTP, we first use Unified Modeling Language (UML) for analyzing the protocol requirement and defining the protocol engine architecture. Next, we use Software Development Language (SDL) to design the protocol engine in details and then generate the WTP implementation automatically with the aid of SDT The code size of the WTP implementation generated by SDT is 62% larger than the other three implementations. However, its throughput and system response time for transaction processing is almost equal to the other three implementations when the number of concurrent clients is less than 3,000. If more than 5,000 concurrent clients tries, the transaction success rate abruptly decreases to 10% and system response time increases to 1,500㎳, due to the increased protocol processing time. But, it comes from the fact that the load overwhelms the capacity of the PC resource used in this experimentation.

The technologies of domestic user programs are not enough to convert address convert information, which was collected via port redirection server, to user traffic. Generally traffic redirection technology is a special purpose technology for I/O traffic via network device. L4 switch needs various additional costs and devices to achieve this special purpose. To solve this problem, there appears need for a central management of control and monitoring by centralizing traffic at one position regardless of network structure and it is necessary to realize redirection function of switch at network layer. Therefore this study offer development of traffic central control system through protocol redirection of client-side.

The connection based TCP protocol provides reliable packet delivery, but it takes certain overhead compare to the connection-less UDP protocol. Thus, 3GPP devise the upper-layer RLC protocol which provides reliability based upon the UDP protocol. Consequently, each implement of a base station and/or mobile terminal require the development of the RLC protocol, and it must qualify various interoperable tests. In this paper, we implement a testbed which verifies the RLC protocol under various packet losses/inversion circumstances of networks. Finally, we propose our testbed as the RLC protocol tester for the developments.

In this paper, we developed a multi-protocol controller based on SoC and embedded Linux and applied it to integrate with BAS in a unified TCP/IP socket communication. The multi-protocol controller integrates control networks of RS-485 and LonWorks devices to BAS. The system consists of three-tier architecture, such as a BAS, a multi-protocol converter, and control devices. By using UML, we modeled the system architecture. In order to show the feasibility of system architecture, it was applied to a small BAS system. The experimental results show that the multi-protocol controller using embedded Linux is flexible and effective way to develop a building control system.

오늘날 인터넷은 중앙 집중식 웹서버로 컨텐츠들을 서비스하는 방식을 주로 택하고 있으며, 이용자들은 저마다의 홈페이지 서버를 갖길 원하고 있다. 그러나 이런 중앙 집중식 서비스방적을 사용했을 경우 비용적인 측면과 유지 보수 관리적인 문제로 인해 사용자들의 욕구를 제대로 해결해주지 못하고 있다. 본 논문에서는 중앙집중형 웹 컨텐츠 서비스가 아닌 순수한 Peer to Peer 방식의 웹 서비스를 할 수 있는 P2P 웹서버의 개발을 소개하고자 한다. 기본 알고리즘은 Gnutella Protocol을 기본으로 하였으며, 여기에 웹서버를 두고 Gnutella Protocol에서 사용되는 Header외에 웹서버의 존재유무를 파악할 수 있도록 별도로 정의된 Header를 사용하여 쉽게 웹서버의 기능유무 및 위치추적을 가능하게 하였으며, 또한 기존의 Gnutella Protocol과도 호환성을 지니고 있다. 위치 추적 및 검색엔진은 Gnutella Protocol과 유사한 방식을 택했으며, 멀티미디어 파일의 검색 및 업/다운로드가 가능하고, 웹문서의 검색후 원하는 문서를 서비스한다. 즉 Peer가 검색엔진과 클라이언트 및 웹서버의 역할을 동시에 수행하는 순수 P2P 웹 서비스를 개발한다.
