The purpose of this paper was to understand the dynamics of deployment of large mesh antennas, and to provide a numerical method for determining the dynamic stiffness and the driving forces for the design. The deployment structure was numerically modeled using the frame elements. The eigenvalue analysis was demonstrated, with respect to the folded and unfolded configurations of the antenna. A multibody dynamic model was formulated with Kane's equation, and simulated using the pseudo upper triangular decomposition (PUTD) method for resolving the constrained problem. Based on the multibody model, the kinetics of the deployment, the motor driving forces, and the feasibility of the designed deployment structure were investigated.

표면유속계는 비접촉식으로 하천의 유량을 측정하는 방식이기 때문에 효율적이며, 특히 홍수발생시 안전한 측정이 가능하다. 이러한 비접촉식 방식이 갖는 장점으로 인해 홍수기 측정에 표면유속계가 널리 활용되고 있다. 하지만 포인트 방식의 표면유속계의 경우에도 측점마다 측정장비를이동하는 과정에서 어느 정도의 측정시간이 소요되며, 측정 시마다 기본적으로 최소 2~3인의 인력을 필요로 한다. 최근 발생하는 홍수사상은 돌발강우에 의해 발생할 뿐만 아니라 단시간 내에 급격한 수위 및 유량변화가 발생하기 때문에 대응하기 매우 어려우며 특히, 야간에 발생하는 호우사상은 야간측정에 따른 안전 사고가 발생할 우려가 있다. 따라서 본 연구에서는 홍수 시 유량측정에 효율적으로 대응할 수 있는 방안으로 다회선 표면유속계를 이용한 유량측정방법을 실제 하천에 적용하고 표면유속을 이용한 다양한 유량산정방법을 실측결과와의 비교를 통해 적용성을 검토하였다. 표면유속계는 다회선 구성이 가능한 레이다유속계(RQ-30) 5대를 활용하였으며, 금강 본류에 위치한 세종시(햇무리교) 관측소를 대상으로 홍수기 유량측정을 수행하였다. 표면유속을 이용한 유량산정방법으로는 5개 유속계의 측정구간을 합산하는 중간단면적법과 표면유속을 지표로하는 지표유속법을 적용하였으며, 유량산정 결과는 기존 관측소의 수위-유량관계의 환산유량과 ADCP를 이용한 실측유량을 비교하였다. 다회선 표면유속 측정시스템을 이용하여 유량을 산정한 결과, 중간단면적법 및 지표유속법 모두 실측치와의 상대오차가 5% 이내로 비교적 정확한 유량측정이 가능한 것으로 확인되었다. 따라서, 향후 홍수기 유량측정이 어렵거나 위험한 지점을 대상으로 홍수가 주로 발생하는 기간에 일시적으로 설치하여 활용이 가능할 것으로 판단된다.

This research originated from the need to enhance the security of secure multiparty computation by ensuring that participants involved in multiparty computations provide truthful inputs that have not been manipulated. While malicious participants can be involved, which goes beyond the traditional security models, malicious behaviors through input manipulation often occur in real-world scenarios, leading to privacy infringements or situations where the accuracy of multiparty computation results cannot be guaranteed. Therefore, in this study, we propose a signature scheme applicable to secure multiparty technologies, combining it with secret sharing to strengthen the accuracy of inputs using authentication techniques. We also investigate methods to enhance the efficiency of authentication through the use of batch authentication techniques. To this end, a scheme capable of input certification was designed by applying a commitment scheme and zero-knowledge proof of knowledge to the CL signature scheme, which is a lightweight signature scheme, and batch verification was applied to improve efficiency during authentication.

통계청의 '인구주택총조사' 결과(2019년 11월 1일)를 기준으로 발표한 '2019 지방자치단체 외국인 주민 현황'을 보면, 국내 체류 외국인은 2,216,612명으로 지난해인 2018년 2,054,621명에 비해 161,991명(7.9%) 증가했다. 이러한 결과는 우리나라 전체 인구(51,850,705명) 중 4.3%에 해당하며, 외국인 주민 최초 조사 연도인 2006년 536,627명과 비교했을 때 4배 이상 증가한 것을 확인할 수 있다. 국내 이민자들의 수가 증가함에 따라, 우리가 생각해야 할 점은 그동안 다문화 관련 정책적 환경이 급변하였을 뿐 아니라, 환경적 변화에 맞게 정책의 변화도 지속해서 이루어졌다는 것이다. 또한, 다문화가족의 양적 증가뿐 아니라, 거주 기간도 장기화되면서 초기 적응이라는 정책보다 구체적이고 포괄적인 새로운 정책 요구를 파악할 필요성이 대두되고 있다. 따라서 다문화가정 결혼이주여성들의 창업 의지에 미치는 요인들을 연구하는 것은 향후 다양한 다문화 정책 수립 및 창업, 경제활동 활성화에 있어 큰 의미가 있다. 다문화가정 결혼이주여성에 대한 창업 의지에 영향을 주는 요인에 관한 연구는 학문적으로 중요한 의미를 갖는데, 선행연구는 주로 북한이탈주민 및 다문화 이민자의 문화지능 또는 사회체제 등이 창업 의지에 영향을 미치는지 초점을 두어왔다. 본 연구의 목적은 다문화 이주민의 창업 의지에 관한 기존 선행연구들을 바탕으로 다문화가정 결혼이주여성들의 창업 의지에 영향을 미치는 요인을 실증분석해 보는 데 있는데, 해당 요인들을 파악함으로써 앞으로 다문화가정 결혼이주여성들의 창업 활성화를 위한 정부와 대학의 역할을 논의해 보고자 한다. 다문화가정 결혼이주여성들의 창업 의지에 영향을 미치는 영향은 개인적 특성(기업가정신)인 '진취성', '혁신성', '위험감수성', '기회 인식'과 긍정심리자본 특성인 '자기효능감', '희망', '회복력', '낙관주의' 등을 선정하였다. 해당 요인들을 바탕으로 수도권에 거주 중인 다문화가정 결혼이주여성들에게 설문조사를 진행하였으며, 설문조사 결과로 신뢰성 분석과 요인분석, 다중회귀 분석, 상관관계 분석 등을 통하여 본 연구에서 설계한 가설들을 검증해 보고자 한다.

Objective: We analyzed quantification of mitochondria DNA (mtDNA) to investigate the relationship of mitochondria and pathogenesis of PCOS. Materials and Methods: Peripheral blood samples were collected from 28 patients with PCOS who were under the inclusion criteria for PCOS and from 28 healthy controls. Genomic DNA was used to analyze real-time PCR for mtDNA copy number quantification. The mtDNA copy number was compared between the control and PCOS groups. All data was expressed as mean ${\pm}$ SD. Statistical analysis was assessed by t-test. Results: In this study, the mtDNA $C_T$ was $11.67{\pm}0.422$ in PCOS patients and $11.51{\pm}0.722$ in control group, respectively. The mtDNA copy number was $1726410.71{\pm}407858.591$ the patients of in PCOS and $2167887.51{\pm}252459.28$ in control group (p=0.08), respectively. Conclusion: In our study, using real-time PCR, there was a tendency of lower mtDNA copy number in the patients of PCOS when comparing to the control group even though statistical difference was not significant. However, more extensive analysis is required to clarity relationship between mtDNA copy number and pathogenesis of PCOS.
