The TLS protocol suite, which provides transport-layer security far the Internet, has been standardized in the IETF. A TLS session is an association between a client and a server, created by the TLS handshake Protocol. Sessions define a set of cryptographic securi쇼 parameters, which can be shared among multiple connections. The TLS protocol, however, does not address the specific method fur how to manage the existing TLS sessions on the host. This paper proposes an efficient management scheme TLS, based on the principles of trust management.

요검사는 검사실에서 일상적으로 수행되는 기본적인 검사이다. 연구에서 새로운 프로토콜을 포함한 두 가지 수동 현미경검사 방법을 표준화된 chamber 방법과 비교하였다. 시험지검사와 자동 침사물 분석기에서 적혈구 양성 201개와 백혈구 양성인 201개 검체로 구성된 총 402개 검체를 분석 대상으로 선정했다. 적혈구 및 백혈구에 대한 표준화된 chamber 방법과 새로운 프로토콜 방법 간의 상관계수는 모두 r=0.98로, 높은 수준의 상관관계를 나타냈다. 이 두 방법 간의 동일 등급에 대한 쌍별 일치율은 적혈구의 경우 86.1%, 백혈구의 경우 88.6%였으며, 한 등급 차이 내 일치율은 모두 99.5%였다. 반면, 표준화된 chamber 방법과 중·소규모 검사실 방법 간의 일치율은 적혈구의 경우 11.9%, 백혈구의 경우 13.4%로, 동일 등급 일치율이 현저히 낮았고, 한 등급 차이 내 일치율은 각각 67.2%와 74.1%로 나타났다. 급내상관계수 및 Bland-Altman plot을 사용한 분석에서는 새로운 프로토콜이 다른 세 가지 수동 현미경검사 방법에 비해 우수한 일치도를 보인 것으로 확인되었다. 표준화된 chamber 방법과의 높은 상관관계와 일치도를 고려해 볼 때, 새로운 프로토콜 방법을 소변 침사물 표본제작의 표준화된 절차로 권장한다.

The purpose of this study was to establish and provide guidelines for the standardized acquisition and interpretation of diffusion-weighted magnetic resonance imaging (DW-MRI) to improve the image quality and reduce the variability of the results interpretation. The standardized protocol includes the use of high-resolution DW-MRI with advanced techniques and post-processing. The aim of the protocol is to increase the effectiveness of the medical image information exchange involved in the construction, activation, and exchange of clinical information for healthcare use. An organized interpretation form could make DW-MRIs' interpretation easier and more familiar. Herein, the authors briefly review the basic principles, optimized image acquisition, standardized interpretation guidelines, false negative and false positive cases of DW-MRI, and provide a standard interpretation form and examples of various cases to help users become more familiar with the DW-MRI.

본 연구는 아동을 대상으로 기쁨, 슬픔, 분노, 스트레스와 무료함의 다섯 가지 정서를 유발시키는 정서프로토콜을 개발하고 이를 표준화하고자 실시되었다. 심상을 유발하는 이야기 음악 색깔 인형을 이용하여 각각의 정서를 유발시키는 상황을 구성하였다. 또한 정서 평가를 위하여 아동용 정서평가척도를 개발하였다. 아동은 다섯 가지의 정서 상황을 경험한 후, 자신의 정서 상태를 평가하였다. 정서 프로토콜에 대한 평가는 아동의 자기보고와 전문가의 행동 관찰 분석으로 이루어졌다. 연구 결과, 개발된 정서 프로토콜은 각각의 정서를 효과적으로 유발시킨 것으로 나타났다. 연령별 별 비교에서는, 남아보다는 여아가 무료함을 더 강하게 느꼈으며, 학령 이후의 아동은 학령이전의 아동보다 슬픔에 더 민감한 것으로 나타났다.

Purpose: This study was conducted to adapt the standardized evidence-based nursing protocol using the IPC (intermittent pneumatic compression) intervention to prevent venous thromboembolism in surgical patients. Further, an investigation was done to measure knowledge on prevention of venous thromboembolism, surrogate incidence of venous thromboembolism and to assess IPC compliance in the study patients compared with those in surgical patients who underwent IPC intervention due to previous clinical experience. Methods: An analysis was done of the nine modules suggested by National Evidence-based Healthcare Collaborating Agency (NECA) in the adaptation manual of the clinical practice guideline for protocol adaptation. A nonequivalent control group post test design as a quasi-experiment was used to verify the effect of the IPC protocol. Results: There was a significant difference in knowledge of prevention of venous thromboembolism, IPC application time after intervention and the number of IPC applications between the experimental group (n=50) using the IPC nursing protocol and the control group (n=49). However, the symptoms of deep vein thrombosis and pulmonary thromboembolism were not observed in either the experimental group or the control group after the intervention. Conclusion: Results confirm that the standardized IPC nursing protocol provides effective intervention to prevent venous thromboembolism in surgical patients.

Background: Preauricular sinus (PAS) is a common congenital anomaly, and complete excision is recommended to prevent recurrence. However, PAS has a high recurrence rate as a result of incomplete removal due to the high variability of the sinus ramifications, making its treatment challenging. In this study, we standardized the surgical procedure to reduce the complications and recurrence rate and compared the postoperative results between the non-standardized and the standardized groups. Methods: This retrospective study included 97 patients (120 ears) who had undergone PAS excision by a single surgeon between October 2014 and September 2022 and underwent at least 6 months of follow-up. After October 2018, all patients were treated using the standardized method, which comprised the use of magnifying glasses, exploration with a lacrimal probe, the use of methylene blue staining, and excision of a piece of surrounding normal tissue and related cartilage in continuity with the specimen. There were 38 patients (45 ears) in the non-standardized group and 59 patients (75 ears) in the standardized group. Results: Recurrence was observed in six of 120 ears, indicating an overall recurrence rate of 5.0%. Recurrence occurred in five ears (11.1%) in the non-standardized group and one ear (1.3%) in the standardized group. The standardized group had a significantly lower recurrence rate (p= 0.027) than the non-standardized group. Conclusion: We defined a standardized sinectomy protocol and used it for the surgical treatment of PAS. With this standardized method, we were able to reduce the rates of complications and recurrence without the use of a long incision.

프로토콜 reverse-engineering 기술은 unknown protocol 의 스펙을 추출하기 위해서 보통 표준화된 방법이 없어서 대부분 수동으로 스펙을 분석하거나 반자동 방식으로 이를 분석한다. 만약 unknown protocol의 근간이 되는 프로토콜을 알 수 있다면, 이를 이용하여 스펙을 분석할 수 있으므로 자동화되고 정확한 분석이 가능할 것이다. 학습되지 않은 프로토콜을 분류하기 위해서는 특징추출은 매우 중요한 단계 중의 하나이다. 본 논문은 기존 프로토콜을 변형한 프로토콜에 대해서 높은 성능을 갖는 분류기를 개발하기 위해서 몇 가지 특징 추출 알고리즘을 제안하고, 프로토콜의 형태 변화에 강인한 특징추출 알고리즘을 제안한다. 성능 검증을 위해서 8개 공개 프로토콜을 대상으로 학습을 수행하고 이를 변형한 프로토콜을 대상으로 성능 측정을 진행하였다.

The communication protocol for interface among railway signalling systems is designed and established as national standard in Korean from a few years ago. So the communication link for information transmission among railway signalling system can be a good example of application of this standard. Communication protocol which is standardized among Korean railway signalling is considered to apply information transmission. And we confirmed there is no the states of deadlock of livelock in std. protocol which is applied formal verification which is one of the analytic method for inspection of safety characteristics in the design course of protocol. But the safety of protocol has to necessarily accomplish this normal analysis approach about satisfying requirement matters with such this analytic approach. In this paper we analyzed the safety characteristics of standard protocol for Korean Railway signalling through the requirement matters for safety transmission of railway transmission system which is required in international standard. So through this study we confirm whether it satisfies safety requirement matters of the level which require in international standard and tried to confirm whether standard protocol has enough safety character in the real railway field.
