In this paper, we propose the ethernet Inter-Processor Communication (IPC) network architecture and 10gigabit ethernet frame multiplex/demultiplexer architecture for the edge switch system based on Linux that has 10 Gigabit Ethernet (10Gigabit Ethernet) port with 72Gbps capacities. we discuss the ethernet IPC with ethernet switch and we propose design and implementation of ethernet Inter-Processor Communication (IPC) network architecture and multiple gigabit ethernet frame rnultiplexing/demultiplexing scheme to handle 10gigabit ethernet frame instead of using 10gigabit network processor. And then ethernet Inter-Processor Communication (IPC) network architecture and 10gigabit ethernet frame MUX/DMUX architecture is designed verified and implemented.

This study attempted to analyze technology convergence structure and key technology research sectors in bio-health. For this, network analysis was performed based on the patent outcomes achieved through national R&Ds. Then, a patent network was analyzed to derive problems and collect data from the National Science & Technology Information Service. With the five groups obtained through the analysis of IPC network and national R&D patents in bio-health based on a research frame network, topics were chosen based on the bio-healthcare technology system. Then, the technology with the greatest ripple effects was derived and compared to other sectors, suggesting a direction for national R&D investments. It is anticipated that this study would make a contribution to a search for R&D investment direction by additionally analyzing overseas patent data and improving correlation analysis between technology convergence and government-led R&D expenses.

Today, according to the increased importance of industry-university cooperation in the knowledge-based economy, support and the number of researches involved in industry-university cooperation has also steadily increased. But it is true that profits from the outcome of patents resulting from such cooperation, such as technology transfer and royalty fees, are lower than they are supposed to be, because of excessive patents applications, although some of them have little commercial potential. Therefore, this research aims to suggest a way to analyze and recognize patents, which enable efficient industry-university cooperation and technology transfer. For the analysis, data on 1,061 patents was collected from 4 different universities. With the data, a quality-strategy matrix was arranged targeting the industry-university cooperation foundations', US patents owned by universities, text mining, and social network analysis were carried out, particularly focusing on the patents in the advanced quality technology section of the matrix. Then core key words and IPC codes were obtained and key patents were analyzed by universities. As a result of the analysis, it was found that 4 key patents, 2 key IPC codes were drawn for University H, 4 key patents, 2 key IPC codes for University K, 6 key patents, 1 key IPC code for University Y, 14 key patents, and 2 key IPC codes for University S. This research is expected to have a great significance in contributing to the invigoration of industry-university cooperation based on the analysis result on patents and IPC codes, which enable efficient industry-university cooperation and technology transfer.

In this paper, we construct a remote data access interface model using the IPC mechanism based on the monitor concept. A general purpose IPC mechanism which can be used to implement arbitrary forms of communications control over distributed processes in a network environment is developed as a basis to build the framework for the model. The interface model and synchronization mechanisms are presented for providing application processes with remote data access capability using the above IPC mechanism.

TMO (Tim-triggered Message-triggered Object) 는 분산환경에서의 정시보장 컴퓨팅을 목표로 제안된 실시간 객체 모델이다. TMO는 객체 자료저장소(object data store), 주기와 데드라인에 의해 구동되는 쓰레드와 이벤트 메시지 전달에 의해 데드라인 방식으로 구동되는 쓰레드로 구성된다. 이러한 TMO 의 수행을 위해, 윈도우 운영체제상의 WTMOS, 리눅스 상의 LTMOS 와 리눅스 커널 내부에서 TMO를 제공하기 위한 TMO-Linux등의 엔진들이 개발되었다. 이러한 엔진들은 서로 다른 플랫폼을 가진 네트워크 환경에서 논리적 멀티캐스트 채널 방식의 분산 IPC 를 기반으로 TMO 의 분산 컴퓨팅을 지원한다 단, 기존의 분산 IPC 는 UDP 기반의 브로드캐스트 방식을 사용하기 때문에 같은 서브 네트워크에 속한 노드들로만 분산 환경을 구축할 수 있고, 특정 채널을 사용하지 않는 노드에도 메시지를 전달하는 브로드캐스팅 오버혜드가 발생하며, UDP 의 특성에 기인한 신뢰성 저하의 문제를 갖고 있다 본 논문에서는 이러한 단점을 극복하기 위해, TMO 엔진의 분산 IPC 모델에 Channel Binding을 통한 그룹 커뮤니케이션 기법을 도입하고 이를 TCP 기반으로 확장하였다.

RT-eCos3.0은 대표적 분산 실시간 객체 모델인 TMO(Time-triggered Message-triggered Object)의 실행을 제공하기 위하여 공개소스 eCos3.0 기반으로 개발된 초경량 경성 실시간 임베디드 운영체제이다. RT-eCos3.0에서는 분산 컴퓨팅 지원을 위하여 네트워크에 투명한 채널 기반 publisher/subscriber 모델의 멀티캐스트 분산 IPC를 지원하고 있다. 본 논문에서는 이와 같은 기존의 분산 IPC를 이용하여 보다 더 직관적인 분산 동기화 read/write 인터페이스를 제공하는 객체 기반의 분산 공유 메모리 시스템을 설계/구현하였다. 구현된 분산 공유 메모리는 각 로컬 노드의 캐시 객체의 사용으로 가능한 한 최소한의 네트워크 통신으로 동기화가 가능하도록 설계 구현되었다.

In this Study, Social Network Analysis of IoT related patents in South Korea, China, and Japan was conducted from the viewpoint of patent informatics. To this end, 2,526 patents filed by PCT until December 2019 were investigated up to the subclass level of the IPC code. As a result, in the case of South Korea, representative IPC codes are in the order of G06Q, H04L, G06F, H04W, and the highest frequency of interconnection is H04L→H04W, H04W→H04L, H04W→H04B. In China, the representative IPC codes are in the order of H04L, H04W, G05B, G06Q. South Korea has strong technological convergence centered on the G06Q, while China has strong convergence centered around H04L and H04W. Moreover, in China, H04L and H04W have more diverse combinations than in South Korea in Section A, B, G, and H. In the future, it is necessary to study the diversity of technology convergence of H04L and H04W in China.

Data is explosively growing, but many companies are still using data analysis only for descriptive analysis or diagnostic analysis, and not appropriately for predictive analysis or enterprise technology strategy analysis. In this study, we analyze the structured & unstructured patent data such as IPC code, inventor, filing date and so on by using big data analysis techniques such as network analysis and TF-IDF. Through this analysis, we propose analysis process to understand the core technology and technology distribution of competitors and prove it through data analysis.

공정기술의 발달로 인해 GPU는 빠르게 발전하고 있다. GPU는 영상처리뿐만 아니라 한 번에 많은 양의 데이터를 처리하는 범용 작업에도 많이 쓰이고 있다. 한편, 최근에는 3차원으로 코어를 적층하는 3차원 CPU구조에 대해 많은 연구가 수행되고 있다. 3차원 구조는 코어를 수직으로 적층시켜 내부 연결망의 길이를 크게 줄여주어 성능을 크게 개선하는 장점을 가지고 있다. 이를 반영하여 GPU에도 3차원 구조를 적용하여 GPU의 성능을 향상시키려는 선행연구에 맞춰 본 논문에서는 3차원 구조 GPU의 성능 향상을 저해하는 요소들에 대해서 분석해 보고자한다. 본 논문에서는 선행연구에서 밝힌 메모리 인터페이스에서 발생하는 병목현상 이외에도 주 메모리 큐 용량과 네트워크 방식에 따른 3차원 GPU의 성능향상을 실험을 통하여 알아본다. 실험 결과 주 메모리 큐 용량에 따른 3차원 GPU의 IPC는 가장 큰 사이즈와 가장 작은 사이즈의 차이가 4 미만으로 주 메모리 큐 용량은 3차원 GPU의 성능에 큰 영향을 미치지 않는 것으로 분석된다. 주 메모리로의 읽기 또는 쓰기 요청들을 순서대로 저장하는 큐의 역할이 3차원 구조 GPU의 동작에는 큰 영향을 미치지 않기 때문으로 분석된다. 반면 네트워크 방식에 따른 실험에서는 fly 네트워크 방식에 비해서 crossbar 네트워크 방식이 더 빠른 데이터 통신을 가능하게 해주어 crossbar네트워크 방식에서 IPC수치가 약 14 증가함을 알 수 있다. 두 가지 실험을 통하여 3차원 GPU의 성능에 네트워크 방식 차이가 주 메모리 큐 용량 변화보다 더 큰 영향을 주는 것을 확인할 수 있다.

Recently, online social networks have become one of the most representative Internet services and are being used increasingly, which allows people to share information and interact with other people. On the other hand, as the use of OSN is increased, there has been an increased incidence where illegally accessed personal information is used wrongfully. Accordingly, privacy has become a key concern by the users. Regarding the construct of information privacy concerns (IPC), this study explored the antecedents of IPC at the individual personal level - risk appraisal and perceived behavioral control - based on Protection Motivation Theory. Hence, the current paper investigated the moderating effect of gender in the relationship between individual characteristics and IPC. The hypothesized research model was examined with 233 questionnaires of OSN users. The results showed that the positive effects of risk appraisal and the negative effects of perceived behavioral control on IPC are supported. In addition, the moderate effects of gender between risk appraisal and IPC is only supported.
