This article explores connection in community, especially human-machine connection, from a Taoist perspective. To this end, the text first discusses the need for connection and the expansion of the objects of connection. It emphasizes that humanity exists in connection and that the problems facing humanity must be solved through connection. It also points out the importance of connection with human-made artifacts in modern society, unlike in the past, and proposes an expansion of the objects to be connected. Next, as a theoretical basis for connection, it identifies the idea of connection in Taoism and the practice of connection in Taoism, and considers the possibility of human-machine connection in them. Based on these discussions, we consider the implications of human-machine connectivity and the direction it should take. These discussions emphasize the importance and necessity of connection within a community. In addition, by attempting to review Taoist ideas about connection, we will also discuss the contrast of problems faced by humanity in relation to connection, and in particular, we hope to provide an opportunity to take an active and proactive approach to the human-machine connection faced by modern humanity.

GLOBAL THEORY OF VERTICAL RECURRENT FINSLER CONNECTION

Soleiman, Amr Korean Mathematical Society 2021 대한수학회논문집 Vol.36 No.3

The aim of the present paper is to establish an intrinsic generalization of Cartan connection in Finsler geometry. This connection is called the vertical recurrent Finsler connection. An intrinsic proof of the existence and uniqueness theorem for such connection is investigated. Moreover, it is shown that for such connection, the associated semi-spray coincides with the canonical spray and the associated nonlinear connection coincides with the Barthel connection. Explicit intrinsic expression relating this connection and Cartan connection is deduced. We also investigate some applications concerning the fundamental geometric objects associated with this connection. Finally, three important results concerning the curvature tensors associated to a special vertical recurrent Finsler connection are studied.

Experimental study of rigid beam-to-box column connections with types of internal/external stiffeners

Omid Rezaifar,Mohammad Nazari,Majid Gholhaki 국제구조공학회 2017 Steel and Composite Structures, An International J Vol.25 No.5

Box sections are symmetrical sections and they have high moment of inertia in both directions, therefore they are good members in tall building structures. For the rigid connection in structures with box column continuity plates are used on level of beam flanges in column. Assembly of the continuity plates is a difficult and unreliable work due to lack of weld or high welding and cutting in the fourth side of column in panel zone, so the use of experimental stiffeners have been considered by researchers. This paper presented an experimental investigation on connection in box columns. The proposed connection has been investigated in four cases which contain connection without internal and external stiffeners(C-0-00), connection with continuity plates(C-I-CP), connection with external vase shape stiffener (C-E-VP) and connection with surrounding plates(C-ESP). The results show that the connections with vase plates and surrounding plates can respectively increase the ultimate strength of the connection up to 366% and 518% than the connection without stiffeners, in case connection with the continuity plates this parameter increases about 39%. In addition, the proposed C-E-VP and C-E-SP connection provide a rigid and safe connection to acquire rigidity of 95% and 98% respectively. But C-I-CP connection is classified as semi-rigid connections.

어플리케이션의 데이터베이스 시스템 사용이 날로 증가하면서, 사용자 급증에 따른 데이터베이스 시스템에 동시접속 하는 커넥션 처리 방법에 있어 중요성이 부각되고 있다. 이러한 데이터베이스의 커넥션을 효과적으로 처리하기 위해 데이터베이스 커넥션 풀이 도입되었으나, 동시접속 사용자가 증가하는 형태에 따른 커넥션 처리는 미비한 실정이다. 본 논문에서는 기존의 커넥션 풀 아키텍처를 개선하기 위하여 주 커넥션 풀 이외에 보조 커넥션 풀을 추가하였다. 또한 두 커넥션 풀의 연결을 관리하기 위하여 커넥션 풀 브로커를 정의하였다. 커넥션 풀 브로커는 주 커넥션 풀이 한계에 도달하였을 때 보조커넥션 풀로 연결을 제어한다. 실험을 통하여 동시접속 사용자가 급격히 증가하는 형태의 요청처리에 있어, 기존 데이터베이스 커넥션 풀 구조와 비교해서 응답시간의 향상된 결과를 확인하였다. The use of database system in application increases day by day. This brought out the DBMS interconnection access problem with rapid increase of the user. To solve these database connection problem, database connection pool has been presented. However, there is much to be desired on user's interconnection access. To improve previous connection pool architecture, we have designed the sub connection pool besides main connection pool in this paper. We defined connection pool broker to manage both main and sub connection pool connection. When main connection pool reached its limitation, connection pool broker transfers a connection from a main connection pool to a sub connection pool. When the interconnection access user increased rapidly, we have proved that the suggested sub pool architecture is more effective on response time by comparing it with other existing DBMS connection pool architectures using simulation.

경산 임당지역 고분 주‧부곽 유구 형태에 대하여

최봉인(Choi, Bong-in) 한국고대사탐구학회 2016 한국고대사탐구 Vol.22 No.-

경산 임당지역 고분은 대형묘와 중 소형묘가 있으며, 동혈묘광과 이혈묘광에는 주곽과 부곽으로 구분되는 것이 있다. 이 글은 이혈묘광의 묘 배치형태에 따라 직렬형과 병렬형으로 나누고, 이 두 가지 형의 변화를 시기별로 알아보아 이를 통해 사회상을 살펴보았다. 대형묘는 4세기 3/4분기부터 6세기 1/4분기까지 직렬형이 관찰되며, 6세기 1/4분기에 병렬형이 축조되었다. 6세기 2/4분기부터는 대형묘가 조성되지 않았다. 중소형묘는 5세기 2/4분기부터 6세기 1/4분기까지 직렬형이 조성되며, 5세기 4/4분기부터 6세기 3/4분기까지 병렬형이 만들어진다. 6세기 1/4분기부터 병렬형이 대부분을 차지하게 된다. 경주의 영향에 따라 도입된 병렬형은 중 소형묘에서 먼저 차용하였고, 대형묘에서 병렬형이 들어오는 시기에 중 소형묘에는 병령형이 급증한다. 이는 중 소형묘의 병렬형을 사용한 집단이 유입된 것으로 추정되며, 대형묘가 소멸하는 것으로 짐작된다. 중 소형묘의 병렬형 도입은 임당지역에 사회적 위상 변화로 대형묘 집단을 사라지게 하는 계기가 되었으며, 이는 신라의 영향 아래 있는 것으로 보인다. The large-sized and the mid & small sized tombs is in Imdang tombs, Gyeongsan, it is divided two types which is an adjoining grave hole and separate grave hole. A separate grave hole have type of series connection and type of parallel connection, it discusses with time and social change by type of series connection and type of parallel connection. The type of series connection on the large-sized tombs made on from the 3rd quarter of the 4th century to the 1st quarter of the 6th century AD, the type of parallel connection built on the 1st quarter of the 6th century AD. The type of series-parallel connection of the Large-sized grave didn"t construct on the 2rd quarter of the 6th century AD. The type of series connection on the mid & small sized made on from the 2nd quarter of the 5th century to the 1st quarter of the 6th century AD, the type of parallel connection was built from the 4th quarter of the 5th century to the 3rd quarter of the 6th century AD. The type of parallel connection became popular at the 1st quarter 6 century AD. It induced type of parallel connection of the mid & small sized by Gyeongju(Silla). The type of parallel connection was more increased the mid & small sized than the large-sized tombs. It guesses to immigrated group with used the type of parallel connection of the mid & small sized and disappeared the large-sized grave. The type of parallel connection of the mid & small sized graves were introduced in Imdang area, it"s to disappeared the large-sized grave"s group by social change. It seems to influenced by the operation of social system under control of Gyeongju(Silla).

Restoring Connection Method for Sink Mobility Support in Irregular Wireless Sensor Networks

Kwansoo Jung 한국정보기술학회 2017 한국정보기술학회논문지 Vol.15 No.10

In wireless sensor networks (WSNs), the connection between a source and a sink should be guaranteed for supporting sink mobility. Existing studies have proposed a two-tier connection scheme to maintain the connection: global and local connection. The global connection is constructed between a source and a local agent acting a temporary static sink while the local connection consists of the relay nodes located along sink’s moving path. However, the scheme causes data loss in practical environments. When a mobile sink moves inside a hole, which is the area having no nodes, the local connection is disconnected due to the limited communication range of nodes. The disconnection lead to data loss until global connection is reconstructed. In this paper, we propose a restoring connection scheme for supporting sink mobility in irregular environments. Proposed scheme detects the disconnection at the boundary of a hole and makes the boundary nodes keep the connection information thereby restoring the connection immediately.

Glulam Beam-to-Column Connection with Coupled Steel Rods with Screwheads: Concept and Experimental Verifications

Zhan Shu,Bo Ning,Hanlin Dong,Zheng Li,Zengxin Peng,Yiyu Yang 대한토목학회 2023 KSCE Journal of Civil Engineering Vol.27 No.6

The bolted connections with slotted-in steel plates are basic beam-to-column connections of modern post-and-beam timber building structures. However, due to significantly pinched rotational behaviors, the moment resistance of such connections are usually ignored in design. In this study, the connection-level moment resistance is enabled for modern glulam frame structures with an innovative connection design. A pair of long steel rods with screwheads is designed to generate a force couple at the sides of the connection. The proposed connection could be considered as the key lateral force resisting component, indicating a significant reduction of lateral braces and shear walls. Specimens of the target connection were carefully designed and tested in the lab to obtain their mechanical properties and failure modes. Finite element models were established and calibrated according to the tested data. The moment-rotation curves of the new connection could be easily estimated through a fitted formula. Moreover, the suggestions to improve the proposed connection is also discussed based on the observed damage modes. Results show that the new connection could be treated as rigid moment-resisting connections while the ductility could be further improved.

김응석(Kim, Eung-Sung),정원식(Jeong, Won-Sik),김성표(Kim, Sung-Pyo) 한국산학기술학회 2011 한국산학기술학회논문지 Vol.12 No.6

본 연구에서는 상수도관의 도․송수관등 대형관(700mm 이상)에 주로 사용되고 있는 도복장강관의 품질 및 시공, 유지관리에 영향을 미치는 용접접합의 현황을 조사 분석하고 용접접합의 개선방안에 대하여 연구하였다. 이를 위해 강관의 사용현황 등의 문제점을 조사하고 용접접합별 특성, 그리고 수동 및 자동 용접접합을 비교 분석하여 기 술적, 경제적으로 효과적인 방안을 제시하고자 하였다. 본 연구에서 비교 분석한 용접접합별 특성 검토 결과, 상수도 관로의 관경 700mm - 3,000mm의 현장 시공시 자동용접공법이 수동용접공법에 비해 순공사비 대비 평균 9% 절감되 며, 용접공정만 비교시에는 평균 13.5% 이상 절감될 것으로 판단된다. 특히, KS상 강관 진원도에 대한 허용치가 크 며 대부분 겹치기 이음으로 되어있는 국내 현실에서 작업환경이 열악한 경우 진원확보를 위한 시간이 무한정 소요될 수 있어 실제적인 절감액은 더욱 차이를 보일 것으로 사료된다. The welded connection is known as an essential factor for establishing qualified construction and/or maintenance of wrapped steel pipe. In this study, welded connection conditions in the coated pipes with large diameter (over 700 mm) in Korea water distribution systems were estimated for suggesting technically and economically available welded connection method. For the study analysis, current steel pipe usage and accident cases were investigated. In addition, the characteristics of each welded connection method and automatic or manual connection techniques were also compared and estimated. As results, automatic welded connection method is superior than manual welded connection method in aspect of pure construction cost (average 9%) or pure welded connection cost (average 13.5%). When the poor welding-working situations in Korea are considered such as high tolerance of out-of-roundness in KS regulation, a number of lap joint welded connections, the real cost benefits of automatic welded connection should be much higher than those of manual welded connections.
