A Paradigm shift is in process in China's foreign policies during Xi Jinping's era. Such changes occur with changing national identities from developing country to great power, and from continental power to continental-maritime power. China's pursuit for sea power embraces its global strategy. Accommodating the new identity of maritime power, China is developing its maritime strategy. New silk-road strategy actively utilizes China's advantage in economy, while avoiding direct military challenges against the U.S. China seeks an associated balance of power with the U.S. On the other hand, China make its determination clear to protect its core national interests, particularly Taiwan straits issue, deploying Anti-Access and Area-Denial strategy. 'Pax-Americana 3.0' and 'China's rise 2.0' have convoluted and evolved in complexity. South Korea faces much tougher challenges ahead in its foreign and security environments.

The Purpose of this paper is to suggest sustainable strategies of the project for developing large-scale environment-friendly agricultural districts (LSEAD). This study used assessment 3 indicators, efficiency, impact and sustainability of environment-friendly agricultural certification area and farmers, management situations of crop-livestock circulation center, educations for environment-friendly farming, changes of farmer's income and so on. This project has contributed to develop environment- friendly agriculture and model of LSEAD. And for sustainable development of LSEAD, it is necessary to renovate crop-livestock circulation centers, promote organic farming of resource-circulation type, converse to non-pesticide or organic farming of low pesticide one, do active marketing activities, establish a governance system of business projects and so forth.

In this study, the physical properties of live garlic at the harvesting season were measured and analyzed as a fundamental study for developing a garlic harvester. A universal testing machine and a machine vision system were used to obtain mechanical and morphological properties of live garlic, respectively. The moisture content of live garlic at the harvesting season was 50% higher than that of dried garlic. The root of live garlic elongated greatly with respect to the applied tensile force. The relationship between the projected area and the weight of a bulb of live garlic was linear. Such a feature would be applied to develop an effective garlic harvester or garlic quality grader. Other useful physical properties of live garlic at the harvesting season were represented in the study.

Contact pressure distribution between PVA brush and semiconductor wafer was measured by developing a test setup which could simulates the post CMP cleaning process. The test set-up used thin film type pressure sensor which could measure the pressure distribution of contact area with the resolution of $15.5ea/cm^2$. As the experimental results, it was verified that there had been severe contact pressure non-uniformity along the axis of the brush and between the adjacent projections on the brush's surface. These results should be considered when developing post CMP cleaning stage or designing the PVA brush.

It is very important to understand the 3-dimensional movement of a robot manipulator in developing a robot manipulator system. The robot design software package is required to test the specification. Usually these robot simulators are turn-key based and not possible to be used on the other robot system. The aim of this paper is to develop a general purpose robot simulator. AutoCad is selected for the developing environment to avoid the difficulties of building a cad system from the scratch. Because Autocad provides a semi-open structure to a Lisp programmer, it is quite successful to achieve the goal of building the simulator. At the moment the kinematic analysis is possible on the package. Further study will be advanced to the application and analysis of dynamic area, which would not be that difficult to be implemented, considering the many third party tools available for Autocad.

The interest about sustainable development of airport operation field has been increased as the aviation industry has been gradually developed and the influence to the neighboring area of airport has been increased. International organization and airport operator have issued a guidance manual with regard to the sustainability specialized in airport by adopting environment friendly rating system and developing a variety of sustainable practices. In this study, the guideline of sustainability manual appropriate to the local airports will be suggested by reviewing a variety of reference documents issued from foreign airport operators.

This study is a part of three year project of “A Study on the Development, Evaluation ＆ Outreach of Marriage Preparation Program”. The purpose of this study is to analyse the unmarried and married couples' attitude about marriage and family, marriage preparation status, their needs of marriage preparation program and ingredients of marital happiness to developing base line data of the marriage preparation program. The result showed that communication ＆ conflict resolution, financial management, relationship characteristics are the major contents area to be considered to develop marriage preparation program. Critics and recommendation for need assessment and educational methods were added.

This paper presents the results of tensile characteristics for developing FRP tendon with strand type. The performance targets were decided to compare the tensile characteristics of developing FRP tendon. Test specimens were manufactured by applying some improvements to enhance the tensile characteristics. The influence factors on the tensile characteristics have been found from the test results. Those are the fiber weight fraction, the pitch, the FRP cross sectional area, and the type of external fibers. The tensile characteristics were satisfactory compared to the performance targets.

Developing reliable measures of the environment is important to increase our understanding of the environmental effects on walking among seniors. As a preliminary study for developing an instrument for measuring walkability of seniors' environment, the purpose of this study are to identify important assessment indicators associated with seniors' walking and to test their reliability using inter-rater and intra-rater reliability methods. A set of assessment indicators was identified through literature review, and field studies by trained raters were conducted in three senior centers located in Seongnam area in order to test reliability of the audit tool. The results indicated high percent agreement for most indicators and overall 91.6% and 86.1% of items assessed had good or medium inter-rater and intra-rater reliability, respectively. The reliable assessment indicators would provide reliable data for use in community-based audits of built environment in relation to walking among older adults. The findings showed that the indicators of aesthetics had lower reliability compare to safety, convenience, and access. Rater training with various images would improve rater agreement while reduce rater bias.

오늘날 측량장비 개발의 급속한 발전과 더불어 정밀도가 많이 향상되고 있고 컴퓨터를 이용한 지형공간정보체계기술의 발달로 더욱 정밀한 3차원 지형의 재현이 가능하게 되었다. 그런데 실제 현장에서 이루어지고 있는 면적 및 체적산출방법에 있어서는 재래적인 측량방법인 평판측량으로 지형을 만들어낸 후 구적기나 기타 다른 방법을 통해서 2차원 면적을 산출한다. 여기에 일정량의 경사보정계수를 곱하여 3차원 면적을 산출하는 방법을 사용하고 있다. 본 연구에서는 재래적인 측량방법 및 면적산출방법에 대한 비효율성 및 비정밀성을 제시하고 광파거리측량기와 GPS를 이용하여 불규칙삼각형방식과 격자형방식으로 측량을 실시하였다. 두 가지 측량데이터를 가지고 각각의 방법에 따라 3차원 지형모델을 구축한 후 2차원 및 3차원 면적을 산출하였으며 재래적인 측량방법을 이용한 면적산출량을 기준으로 불규칙삼각형방식과 격자형방식으로 산출한 면적산출량을 비교 분석함으로써 정밀하고 효율성이 높은 3차원 면적산출기법을 제시하였다.
