무선 센서 네트워크에서의 에너지 효율적인 클러스터 헤드 선출 알고리즘

최경진,윤명준,심인보,이재용,Choi, Koung-Jin,Yun, Myung-Jun,Sim, In-Bo,Lee, Jai-Yong 한국통신학회 2007 韓國通信學會論文誌 Vol.32 No.6b

무선 센서 네트워크에서 클러스터링은 클러스터 헤드(cluster head) 노드가 클러스터 멤버 노드의 데이터를 병합(aggreation)하여 싱크(Sink)로 전송함으로써 노드 간 통신의 양을 줄이게 하고 클러스터 내부적으로는 TDMA 스케줄에 기반하여 클러스터 헤드가 클러스터 멤버 노드의 스케줄을 조정함으로써 노드의 슬립타임을 연장하게 한다. 제안하는 ECS(Energy efficient Cluster-head Selection) 알고리즘은 에너지가 제한되는 센서 네트워크의 수명 향상을 위하여 노드 자신의 요소(factor) 즉, 자신의 초기 에너지 및 현재 에너지, 클러스터 헤드에 의해 병합된 클러스터 내 노드들의 데이터가 싱크로 전송되는 각 라운드, 노드 자신이 클러스터 헤드로 선출(selection) 된 수를 이용하여 확률적인 방법으로 클러스터 헤드를 자가 선출한다. Clustering protocol of Wireless sensor networks(WSNs) not only reducing the volume of inter-node communication by the nodes's data aggreation but also extending the nodes's sleep times by cluster head's TDMA-schedule coordination. In order to extend network lifetime of WSNs, we propose ECS algorithm to select cluster-head using three variables. It consists of initial and current energy of nodes, round information and total numbers which have been selected as cluster head until current round.

최경진,이용현,Choi, Kyung-Jin,Lee, Young-Hyun 한국반도체디스플레이기술학회 2009 반도체디스플레이기술학회지 Vol.8 No.4

In this paper, the laser cutting characteristics of the flexible PCB using high power Nd:YAG UV laser were investigated. A specific FPCB model was selected for the experiment. Test sheets were made, which had equal materials and layer structure to those of the outline (OL) region and the contact pad (CP) region in the FPCB. The experiment is made up of two stages. In the first stage of the experiment, the laser cutting fluence was found, which is the threshold fluence to cut the test sheets completely. The laser cutting fluence of the OL sheet is $1781.26{\sim}1970.16\;J/cm^2$ and that of the CP sheet is $2109.34{\sim}2134.34\;J/cm^2$. In the second stage, cutting performance and its qualities were analyzed by the experiment. The laser cutting performance remained almost unchanged for all laser and process parameter sets. The average cutting width (top side/bottom side) of the OL sheet was $40.45\;{\mu}m/11.52\;{\mu}m$ and that of the CP sheet was $22.14\;{\mu}m/10.93\;{\mu}m$. However, the laser cutting qualities were different according to the parameters. The adjacent region of the cutting line on the OL sheet was carbonized as the beam speed was low and the overlap coefficient was high. The surface quality around the cutting line of the CP sheet was about the same. Carbonization and debris occurred on the surface of the cutting line. As a result of the experiment, the cutting qualities were better as the overlap coefficient was made low and beam speed high. Therefore, the overlap coefficient 2 or 3 is proper for the FPCB laser cutting.

With the advance of technology, the order-made clothes gradually give way to ready-made clothes. It is already well-known that more than 80 percentage of Japanese are choosing ready-made clothes while less than 5 persons out of 100 are spending their money and valuable time to have their clothes order-made in the United States. One of the fundamental steps to reach the system of mass production of clothes is recognized as a reasonable sizing system. Reasonable can be interpreted optimum in the sense of minimum loss from both producers and customers. This paper desires the methodology to obtain the sizing system utilizing the human body measurement data. The suggested methodology could be extended to the sizing system for the design of other items including industrial equipments.

최경진 ( Kyung Jin Choi ),김수성 ( Su Sung Kim ),선혁창 ( Hyeok Chang Sun ) 한국연금학회 2016 연금연구 Vol.6 No.2

우리나라는 자녀 교육비 특히 대학학자금 마련이 가계의 경제적 부담은 물론 부모의 노후준비에 커다란 장애물로 작용하고 있다. 우리나라의 대학등록금 수준은 OECD 국가 중 미국에 이어 세계2위를 차지하고 있다. 이에 반해 대학학자금 마련을 위한 대책은 매우 부족한 상황이다. 대학학자금 마련을 위한 근본적인 해결방안을 모색하기 위해 본 연구는 현행 학자금 마련수단의 현황 및 문제점을 파악하고자 하였다. 다음으로 국가의 직·간접적 지원이 활발한 캐나다의 적격교육저축플랜(Registered Education Savings Plan)의 사례를 조사·분석하였다. 이를 바탕으로 우리나라에 맞는 대학학자금 저축플랜의 도입 및 세제지원 방안을 다음과 같이 제시하였다 구체적으로 대학 학자금 저축플랜은 연금저축과 유사한 성격임을 감안하여 부담금 납입, 적립금 운용, 급여 수령 등의 단계 별 지원방안을 고려하였다. 먼저, 부담금 납입액에 대한 세액공제 적용과 더불어 보조금 등 부담금 지원방안이 필요하다. 적립금 운용 시에는 가입자의 투자성향 및 자녀연령을 고려한 자산운용방안 마련이 중요하다. 또한 학자금 지출 목적에 부합한 급여인출을 유도하기 위한 저율의 세제적용과 중도 해지 시 패널티 부과의 필요성을 언급하였다. 이와 더불어 학자금으로 미 사용될 경우 타 수익자 지정을 통해 학자금 저축계좌를 계속 유지하거나 가입자 노후소득으로 전환하는 등의 유기적인 연계가 필요함을 주장하였다. In Korea, educational expenditure for children, especially college tuition, is serving as a financial burden of household and a big obstacle in preparing for retirement income of parents. The level of college tuition of our country is ranked second in the world after the United States among OECD countries. On the contrary, there are critically low measures for preparation of college tuition. To search for fundamental solutions for preparation of college tuition, this study intended to investigate the present condition and problems of the current means of preparation of college tuition. Then, this study investigated and analyzed a case of Registered Education Savings Plan of Canada with active direct and indirect national support. Based on the findings, this study suggested the following introduction of college tuition savings plan and appropriate tax support measures for our country. To be specific, this study considered support measures by stage of levy payment, management of accumulated fund, and receipt of salary by considering that notions of college tuition savings plan and pension savings are similar. First, tax deduction application for contribution payment as well as support measures of contribution as grant would be necessary. Investment propensity of subscriber and asset management plan that considered child`s age are important in management of reserve funds. Also, this study mentioned about the necessity of application of low tax rate and imposing penalty for early termination for inducing benefit withdrawal that fits the purpose of tuition expenditure. This study insisted that maintaining the college savings plan or changing into retirement income through designated beneficiary are necessary when it is not used for tuition.

`United Nations Convention on the Use of Electronic Communications in International Contracts` (hereinafter “Convention”) was signed in 2008 caused of its needs in electronic environment, but has not been ratified so far. If ratified, Electronic Communications Convention shall have same effect as a domestic statutory law through the process of ratification without consent of National Assembly. From this point of view, this paper deals with the question of whether Korea has to ratify the Convention and the possibility of harmonization with domestic law by introducing the content of Electronic Communications Convention and comparing with related domestic laws. For this, this paper introduces main features of the Convention, such as objective of the Convention, main principles on which the Convention is based, sphere of application, party autonomy, definitions, interpretation standard, location of the parties, information requirements, legal recognition of electronic communications, form requirements, time and place of dispatch and receipt of electronic communications, invitations to make offers, automated message system, availability of contract terms, error in electronic communications, etc. After looking into such issues, this paper suggests that Korea would better positively and actively consider the ratification of the Convention because Korea is the leading country in ICT and Korean legal system on ICT is no special problem which hinders the ratification. Regarding to the issue of equivalence between the Convention applying to international electronic contract and municipal laws applying to domestic electronic transactions, there are restrictive scope of domestic law provisions necessary to be modified, such as provisions related location of the parties, form requirements, etc. Even those necessity for modification of law is not urgent. In conclusion, it is necessary to ratify the Convention to play the key role as a leading country in the international electronic environment.

최경진(Kyung-jin Choi) 한국지역개발학회 2020 한국지역개발학회 학술대회 Vol.2020 No.10

주택연금은 소득의 안정성 및 충분성 측면에서 중산층 이하 고령층의 유용한 노후소득 마련 수단 일 뿐 만 아니라 노후 소득마련에 따른 자신감 형성, 자신의 익숙한 환경에 거주할 수 있는 심리적 안정에도 도움을 준다. 본 연구는 최근의 주택금융공사의 ‘2019년 주택연금 수요실태조사’ 자료를 바탕으로 비례오즈 로짓모형을 이용하여 주택연금 이용자의 이용만족도에 영향을 주는 요인을 살펴보았다. 그 결과, 주택연금 이용만족도에 영향을 주는 주요 요인은 노후대비 자산충분성, 정부의 노후지원 정도, 중도상환계획, 자녀수, 배우자 유무, 주택연금 가입 전 고려사항, 자산보유정도, 수입출처 등으로 나타났다. 반면, 중도상환에 영향을 주는 요인은 연령, 배우자 유무, 소득으로 나타나 주택연금의 만족도 향상을 위해서는 기본적으로 개인별 재무적 상황과 주택연금제도에 대한 충분한 이해가 선행되어야 하며, 정책적 측면에서는 꾸준한 제도개선노력이 뒷받침 되어야 한다는 점을 시사하고 있다. This study examined the factors affecting the satisfaction of the use of reverse mortgage users by using the proportional odds logit model based on the latest data from the ‘2019 reverse mortgage demand survey’ by the Housing Finance Corporation. As a result, the main factors influencing the satisfaction of using the reverse mortgage were sufficient asset level for old age, sufficient government support system, interim repayment plan, number of children, consideration for reverse mortgage, asset level, and income source. The reverse mortgage is not only a useful tool for preparing income for old age groups under the middle class due to the stability and sufficiency of income, but also helps to build confidence in retirement income and psychological stability to live in their familiar environment. In addition, it suggests that, in order to build satisfaction with the reverse mortgage, it is necessary to consider and understand the financial situation of the individual and the reverse mortgage system in advance, and in the policy aspect, steady efforts to improve the system should be supported in the future.
