Background: A major problem with cervical cancer screening in countries which have no organized national screening program for cervical cancer is sub-optimal participation. Implementation of self-sampling method may increase the coverage. Objective: We determined the agreement of cytological diagnoses made on samples collected by women themselves (self-sampling) versus samples collected by physicians (Physician sampling). Materials and Methods: We invited women volunteers to undergo two procedures; cervical self-sampling using the Evalyn brush and physician sampling using a Cervex brush. The women were shown a video presentation on how to take their own cervical samples before the procedure. The samples taken by physicians were taken as per routine testing (Gold Standard). All samples were subjected to Thin Prep monolayer smears. The diagnoses made were according to the Bethesda classification. The results from these two sampling methods were analysed and compared. Results: A total of 367 women were recruited into the study, ranging from 22 to 65 years age. There was a significant good agreement of the cytological diagnoses made on the samples from the two sampling methods with the Kappa value of 0.568 (p=0.040). Using the cytological smears taken by physicians as the gold standard, the sensitivity of self-sampling was 71.9% (95% CI:70.9-72.8), the specificity was 86.6% (95% CI:85.7-87.5), the positive predictive value was 74.2% (95% CI:73.3-75.1) and the negative predictive value was 85.1% (95% CI: 84.2-86.0). Self-sampling smears (22.9%) allowed detection of micro-organisms better than physicians samples (18.5%). Conclusions: This study shows that samples taken by women themselves (self-sampling) and physicians have good diagnostic agreement. Self-sampling could be the method of choice in countries in which the coverage of women attending clinics for screening for cervical cancer is poor.

The core of the foreign policy of the Yoon Suk-yeol government is the promotion of active economic and security diplomacy as indicated in Policy Tasks No. 98. To this end, economic consultative bodies such as Regional Comprehensive Economic Partnership Agreement(RCEP), Comprehensive and Progressive Agreement for Trans-Pacific Partnership (CPTPP), and Indo-Pacific Economic Framework (IPEF) are taking the initiative to respond to the formation of supply chain, human rights, environment, and digital-related norms, and actively support Korean companies' overseas expansion. Due to the nature of the Ministry of Oceans and Fisheries (MOF) as an organization established centered on the space of the ocean, the MOF faces difficulties in bringing the functions of other ministries into the space of the ocean. Considering the vision, objectives, and detailed plans of the MOF, the contribution of the MOF in the field of active economic security, one of the main foreign policies of the Yoon Suk-yeol government, is perhaps too obvious. However, since the re-launch of the MOF, the ODA budget for the oceans and fisheries sector is too small compared to other ministries, so even if new policy demands are discovered, there are many difficulties in implementing these policies in practice. Recognizing these problems, this paper examines the background and contents of foreign policies that have been promoted for the efficient promotion of RCEP, CPTPP and IPEF and introduces the areas of cooperation in the oceans and fisheries sector in these foreign policies.

2009년 4월 27일 일본과 미국은 항공기 및 부품의 감항성인증을 상호수락하기 위한 항공안전협정(BASA) 및 감항성이행절차(IPA)를 체결하였다. 항공안전협정이 해당 민간항공당국이 수행해야 하는 법적 책임을 경감시키지는 않는다. 다만, 역량있는 상대국가의 감항당국이 해당 민간항공당국을 대신하여 자국의 항공기 인증제도에 필적할 만한 방법으로 수행한 인증기능을 인정하는 방법을 통하여, 해당 민간항공당국은 적합성판정을 함에 있어서 대체방법으로 활용하는 것이다. 이를 통해 항공안전협정은 안전을 저해하지 않으면서 여러 국가의 인증에 소요되는 비용과 시간을 경감시키면서 교역을 촉진하는 데 기여하고 있는 것이다. 본 논문에서는 가장 최근에 미국과 BASA를 체결한 일본의 항공기 인증제도 및 항공안전협정 체결 현황에 대하여 제시한다.

우리나라는 1983년에 절충교역 제도를 도입하여 국방 전력증강의 효율적 수단으로 활용하여 왔다. 그런데 절충교역은 계약체결이 획득기술에 대한 가치평가 결과를 근거로 이루어지기 때문에 국외업체와의 협상 등 업무과정상 지연될 가능성이 존재한다. 절충교역 계약체결이 지연되면 무기체계 구매사업이 늦어져 국방 전력증강에 심각한 악영향을 주게 된다. 따라서 본 연구에서는 절충교역 계약 과정, 특히 계약 소요기간에 영향을 미치는 요인들을 통계적으로 분석하여 소요기간을 결정하는 요인을 규명하고자 하였다. 영향 요인으로는 국외업체 국적, 사업진행 형태 (경쟁/단독 입찰), 사업 특성 (최초/계속 사업), 최초 제안기술의 수, 국내 무기체계 분야별 국방과학기술수준, 기본사업 규모 등 6개를 고려하였다. 가설 검증은 절충교역 계약이 체결된 25개 사업을 대상으로, 상관분석 및 다중회귀분석을 통하여 이루어졌다. 상관분석 결과에 의하면, 기본사업 규모, 최초 제안기술의 수, 사업 특성 등이 종속변수인 절충교역 계약 기간과 양의 상관관계를 갖고 있음을 알 수 있었다. 다중회귀분석 결과에서는 기본사업 규모와 사업진행 형태가 절충교역 계약 소요기간에 유의한 영향을 미치는 것으로 나타났다.

To help improve the current government practice of direct damage-compensation policies, resulting from the loss of profit, sustained by Hanwoo farmers, as a result of the recent Korea-U. S. Free Trade Agreement (FTA), this research aims to examine any problems or issues caused by said policies. To accomplish this task, we have established Hanwoo-SIMO model and estimated the damage of Hanwoo farmers, one without the implementation of the FTA and another with the FTA, to compare and contrast the two. We then analyzed the efficacy of the current government policies. According to our analysis, the current direct compensation policies for the loss of profit on the part of Hanwoo farmers are insufficient. To address this problem, we recommend the government enact a new direct damagecompensation law to address the following issues. First, as the base formula of damage-compensation, the government should use current price of the beef rather than the annually changing flexible price. Second, the flexible control index should remain fixed at 1.0 rate while the government prepares the adequate amount of the damage compensating direct payment resulting from the FTA. Third, the direct government compensation policy should extend beyond the current 15 years (2013-2026) as the profit loss is expected to increase after the midpoint of the FTA.

A two dimensional discrete vortex method (DIVEX) has been developed at the Department of Aerospace Engineering, University of Glasgow, to predict unsteady and incompressible flow fields around closed bodies. The basis of the method is the discretisation of the vorticity field, rather than the velocity field, into a series of vortex particles that are free to move in the flow field that the particles collectively induce. This paper gives a brief description of the numerical implementation of DIVEX and presents the results of calculations on a recent suspension bridge deck section. The results from both the static and flutter analysis of the main deck in isolation are in good agreement with experimental data. A brief study of the effect of flow control vanes on the aeroelastic stability of the bridge is also presented and the results confirm previous analytical and experimental studies. The aeroelastic study is carried out firstly using aerodynamic derivatives extracted from the DIVEX simulations. These results are then assessed further by presenting results from full time-dependent aeroelastic solutions for the original deck and one of the vane cases. In general, the results show good qualitative and quantitative agreement with results from experimental data and demonstrate that DIVEX is a useful design tool in the field of wind engineering.

This paper focuses on the design for Rx/Tx switch module of GSM(global standard mobile) band, characterization of a miniature, low power and dual-band implementation of the front-end switch module with low-pass filer And the effort to make agreement between the simulated design and the measured data for these solutions takes the place through accumulated design and manufacturing data library. We present the design, modeling and measurement of switch module integrating GSM Rx/Tx switching circuit and LPF(low pass filter) on a LTCC(low temperature co-fired ceramic) substrate. For GSM application, insertion and return loss of the low pass filter designed was less than 0.3 dB which was less than 12.7 dB at 900 MHz. The LTCC switch module contained 10 embedded passives and 3 surface mount components integrated on 4.6$\times$4.8$\times$1.2 mm, 6-layer multi-layer integrated circuit. The insertion loss of switch module measured at 900 MHz was 11 dB. In both of the design approach yielded excellent agreement between measured and simulated results.

Purpose - This paper aims at analyzing the functions and effectiveness of the cooperation agenda in Free Trade Agreements (FTAs), focusing on the cases of Asian countries. This paper estimates the contribution of this agenda to the sustainable development in Asia by providing the 'side payment' of the economic integration that encourages foreign investment and change in global value chains (GVC). Design/methodology - This study analyzes the functions of the cooperation chapter in FTAs by applying the cooperative game theory and reviewing the structures of the related FTAs. Also, as an empirical study, the existing FTA provisions and related development assistant programs in Asia are reviewed in this paper, especially focusing on the FTAs signed by Korea. Findings - Our main findings can be summarized as follows: The drawback of the economic integration, which would be the imbalanced economic benefit, can be redressed by the cooperation chapter in FTAs functioning as a 'side payment'. Indeed, as the examples of Korean FTAs show, more foreign investment and the GVC expansion in Asian countries have been encouraged thanks to the implementation of the cooperation chapters. Originality/value - This paper attempts to find how a legally binding agreement would influence the cooperation agenda in Asia which has never been analyzed despite the increasing number of so-called 'cooperation' chapters in the FTAs.

Integrated Project Delivery는 기존 발주방식 (설계시공일괄 발주방식, 설계시공분리 발주방식, 건설사업관리 발주방식)의 대안으로 제시되고 있다. 다수의 국외 IPD 관련 연구들은 IPD의 계약적 측면뿐만 아니라 IPD의 업무수행방식 측면에서도 IPD 연구에 접근하고 있다. 그러나 대부분의 국내 IPD 관련 연구들은 IPD의 계약적 특성에만 초점을 맞추고 이것이 심각한 문제인 것으로 간주하고 있는데, 현재 국내 규제와 법적 한계로 인해 다자간 계약이 불가능하므로 이런 국내 건설환경에서는 IPD가 도입되기 어렵다는 주장이다. 하지만 본 연구는 국내 시스템이 변화하길 기다리는 대신 IPD가 업무수행방식 측면에서 도입될 수 있음을 보여주고자 한다. 따라서 이 연구의 목표는 IPD 계약이 체결되지 않은 프로젝트들의 성과와 IPD 계약이 체결된 프로젝트의 성과를 비교함으로써 IPD 계약적 특성이 IPD를 적용한 프로젝트에서 필수조건이 아님을 보이는 것이다. 본 연구는 미국 5개 IPD 사례와 국내 1개 프로젝트의 참여자들로부터 설문데이터를 확보하여 사례조사를 두 단계로 수행하였다. 첫째로 IPD 계약을 체결하지 않은 미국 4개 사례의 IPD 특징요소 적용여부와 그에 따른 성과를 비교하고, 둘째로 IPD 계약을 체결한 미국 사례와 IPD 특징요소를 프로젝트에 도입한 국내 사례에 대해서 첫 번째 단계와 같은 내용을 비교하였다. 연구의 결과로 IPD 특성의 자유롭고 유연한 도입을 통해 국내 건설의 생산성 도모와 협업환경 조성을 통한 건설 환경의 개선 및 발주자와의 신뢰관계 구축에 도움을 줄 것으로 기대한다.
