글로벌 식량 위기의 해결책이자, 4차 산업혁명 시대의 새로운 성장동력으로서 스마트농업이 등장하였다. 본 연구는 해외 주요국의 스마트농업 동향을 통해 각 국가의 농업 지식과 경험이 특정 농업 환경에서 어떻게 발현되는지 살펴봄으로써 스마트농업의 공간성을 밝히는데 목적이 있다. 이를 위해 스마트농업 기술 수준에 따라 중국, 일본, 네덜란드, 미국을 대표적인 사례로 선정하여 각 국가 스마트농업 정책의 방향성, 거버넌스, 주력 분야와 기술을 살펴보았다. 그 결과 지역의 경제·사회·문화 및 생태적 맥락으로부터 탈맥락화 시키는 방향으로 작동하는 표준화 전략과 지리적 특성을 반영하여 각 국가별 스마트농업 모델을 구축하고자 하는 국지화 전략이 동시에 작동하며 각 국가의 정책과 기술을 형성하는 것으로 판단된다. 본 연구는 국가적 스케일에서 스마트 농업 정책과 현황을 살펴보는 시도로써 농업기술 지리 및 농업지식생산의 지리를 탐색하기 위한 연구의 토대로 활용한다.

Many students have misconceptions about the direction of force of moving objects, but development of teaching strategy for conceptual change is not easy because the direction of force of moving objects can not be observed directly. Therefore, we devloped demonstration using table tennis ball connected with spring in the water, in which a ball always move to the direction of force of moving objects. This study is to investigate students' responses on the demonstrations designed to generate cognitive conflict and to understand more deeply the process of conceptual change. To do this, five questions were administrated to identify students' preconceptions about force and motion, and interview was conducted using demonstrations, and the process of interview was recorded by video camera. About half of students changed their preconceptions by observing the demonstration. However about thirty percentage of students did not change their preconceptions even though they observed demonstration correctly, among these students, some students simply rejected the observation, doubted the process of demonstrations, or reinterpret the result of observation to preserve their own preconceptions.

In the zigzag milling operation, an important issue is to design a machining strategy which minimizes the cutting time. An important variable for minimization of cutting time is the tool path length. The tool path is divided into cutting path and non-cutting path. Cutting path can be subdivided into tool path segment and step-over, and non-cutting path can be regarded as the tool retraction. We propose a new method to determine the cutting direction which minimizes the length of tool path in a convex or concave polygonal shape including islands. For the minimization of tool path length, we consider two factors such as step-over and tool retraction. Step-over is defined as the tool path length which is parallel to the boundary edges for machining area and the tool retraction is a non-cutting path for machining any remaining regions. In the determination of cutting direction, we propose a mathematical model and an algorithm which minimizes tool retraction length in complex shapes. With the proposed methods, we can generate a tool path for the minimization of cutting time in a convex or concave polygonal shapes including islands.

One of the important point in the development of urban fishing villages is to create various alternatives providing appropriate environment of fishing villages by keeping the characteristics of each fishing village. The purpose of this study is to suggest an urban-planning alternation to main fishing villages in Busan city by adaptation of the framework analysis, by adapting differentiated strategy considering the characteristics of each fishing village and by having similarities of development direction the whole city. At the same time this study is to propose against imprudent development of certain fishing villages or staying physical issues of existing plans about fishing villages. So this study is willing to visualize the frame of village and suggest the development direction after analyzing the 6 fishing villages(Songjeong village, Millak village, Daebyeon village, Gongsu village, Duho village, Dongam village) representing Busan city by using the five development types extracted from the type of cultural city. In addition, this study is used the framework analysis as the visual tool of potential elements and development direction in fishing villages by making frame of the most revealing cultural or environmental elements.

The concept of criterion function is proposed as a framework for comparing the geometric and computational characteristics of various nonlinear programming approaches to linear programming such as the method of centers, Karmakar's algorithm and the gravitational method. Also, we discuss various computational issues involved in obtaining an efficient parallel implementation of these methods. Clearly, the most time consuming part in solving a linear programming problem is the direction finding procedure, where we obtain an improving direction. In most cases, finding an improving direction is equivalent to solving a simple optimization problem defined at the current feasible solution. Again, this simple optimization problem can be seen as a least squares problem, and the computational effort in solving the least squares problem is, in fact, same as the effort as in solving a system of linear equations. Hence, getting a solution to a system of linear equations fast is very important in solving a linear programming problem efficiently. For solving system of linear equations on parallel computing machines, an iterative method seems more adequate than direct methods. Therefore, we propose one possible strategy for getting an efficient parallel implementation of an iterative method for solving a system of equations and present the summary of computational experiment performed on transputer based parallel computing board installed on IBM PC.

This study aims to report on the problems of the Korean woodcraft in the past and to suggest a new direction for the development strategy, in line with the government policy to promote domestic craft culture industry. This includes the problems of the woodcraft in Korea which have been raising in contest-exhibits organized not only by industry and academia, but also by government. The survey asked 48 people (24 in industry and 24 in academia) shows as follows. The most serious problem shown in industry is the government-sponsored issue and it should be premised on offering the market in this case. The question in academia reports that the academic world little contributes to the development in industrial circles of the woodcraft, and the problematic issues of the contests are the appraisal standard and the method of evaluation. In brief, the government's aggressive support should be always first and foremost for the woodcraft industry which is often confronted with difficulties in research & development and in securing distribution channels due to it' small scale of business. Furthermore, the government-led contest and certificate of qualifications should be redesign for filling the original purpose and throughly carried out for the development of industries. Also university curriculum being far too disconnected from industries now should be focused on the collaboration between industry and university, the training mission and the related seminars to overhaul the contents of the department of the woodcraft and to create a progressive direction for the future accordingly.
