  • This study aimed to develop an agroforestry technology through the participation of local people. The study was conducted in the Makiling Forest Reserve (MFR) of the University of the Philippines Los Banos (UPLB). Diagnosis and Design (D&D) methodology was employed to plan and implement effective research and development projects. Diagnostic interview and direct field observation were conducted to identify the significance of the land-use system and to understand how the system works. As a result of the diagnostic interview and direct field observation in San Vicente, old coconut-based land-use system is shifting to mahogany-based agroforestry system. One of the reasons is due to the very complicated socio-economic and silvicultural factors including lower price of coconut farm products, industry development, lack of labor force, and pest and diseases. Change in land use brought about by the shifting to mahogany-based farming system is slow. Also, mahogany trees are observed to be not well-maintained. However, mahogany based land use system gives farmers' a bigger income as well as environmental benefit. Farmer's cooperation and local forestry policy for CDM were proposed to encourage people's self-restoration effort.

  • This study is firstly aiming at diagnosing the present problems of evaluating the performance, especially in the field of disaster and safety management, of LGA (Local Government Authorities) in Korea. The study also deals with developing alternatives to solve a series of barrier factors revealed during the evaluation process using System Dynamics. This paper therefore presents literature review including the official documents published by the government and the performance evaluation studies of LGA. Moreover the authors analyze the current practice of the CELG (Combined Evaluation of Local Governments) as performance management, address and map a series of barrier factors in the CELG process to elaborate the CLDs (Causal-Loop Diagrams) and find solutions using system thinking with the CLDs. According to the analysis results, the core barrier factors to overcome is lack of proactive indicators/indices in the current practice of the CLEG. The authors therefore recommend to develop more proactive indicators that leads to avoid difficulties in measuring the LGA output, as well as to lessen the burden in competition for rankings and goal of the displaced.

  • Although the $6^{th}$ industry of agriculture, the subject of this research, is a policy that is implemented nationwide, the result or its performance can vary depending on judgment and basic plan of the local government concerned. To overcome this, support of the central government and provincial governments is important, but each rural family, rural area or management unit also has to grasp the reality fast and overcome it through voluntary participation. In addition, local governments of the nation should operate this project efficiently by implementing required support and policies in each field. Local governments should also promote revitalization of local economy by providing help to rural families and management units that implement the $6^{th}$ industry of agriculture through expert consulting, matching of funding paths, and deregulation.

  • We present a new global/local analysis with the aid of MLS(Moving Least Square)-based finite elements which can handle an arbitrary number of nodes on every element side. It give a great flexibility in constructing finite element meshes at the specified local regions without remeshing. Compared to other type global/local analysis, it does not require any superimposed mesh or need not solve the equilibrium equation twice as well as shows an excellent accuracy. To demonstrate the performance of proposed scheme, we will show several examples in relation to capturing highly local stress field.

  • Artificial potential field (APF) is a widely used method for local path planning of autonomous mobile robot. So far, many different types of APF have been implemented. Once the artificial potential functions are selected, how to choose appropriate parameters of the functions is also an important work. In this paper, a detailed analysis is given on how to choose proper parameters of artificial functions to eliminate free path local minima and avoid collision between robots and obstacles. Two kinds of potential functions: Gaussian type and Quadratic type of potential functions are used to solve the above local minima problem respectively. To avoid local minima occurred in realistic situations such as 1) a case that the potential of the goal is affected excessively by potential of the obstacle, 2) a case that the potential of the obstacle is affected excessively by potential of the goal, the design guidelines for selecting appropriate parameters of potential functions are proposed.

  • Application of reduced web beam section (RWBS) as a sacrificial fuse element has become a popular research field in recent years. Weakening of beam web in these connections may cause local web buckling around the opening area which can affect cyclic behavior of connection including: maximum load carrying capacity, strength degradation rate, dissipated energy, rotation capacity, etc. In this research, effect of local web buckling on the cyclic behavior of RWBS connections is investigated using finite element modeling (FEM). For this purpose, a T-shaped moment connection which has been tested under cyclic loading by another author is used as the reference model. Fracture initiation in models is simulated using Cyclic Void Growth Model (CVGM) which is based on micro-void growth and coalescence. Included in the results are: effect of opening corner radii, opening dimensions, beam web thickness and opening reinforcement. Based on the results, local web buckling around the opening area plays a significant role on the cyclic behavior of connection and hence any parameter affecting the local web buckling will affect entire connection behavior.

  • Damage detection based on dynamic characteristics of a structure is one of important roles in structural damage identification. It is difficult to detect local structural damage using traditional dynamic experimental methods due to a limited number of sensors used in an experiment. In this work, a non-contact test stand of fan blades is established, and a full-field noncontact test method, combined with three-dimensional digital image correlation, Bayesian operational modal analysis, and damage indices, is used to detect local damage of a fan blade under ambient excitation without use of baseline information before structural damage. The methodology is applied to detect invisible local damage on the fan blade. Such a method has a seemingly high potential as an alternative to detect local damage of blades with complex high-precision surfaces under extreme working conditions because it is a noncontact test method and can be used under ambient excitation without human participation.

  • The Landscape Act was enacted in 2007 introducing a new procedure of the Local Landscape Agreement and the Local Landscape Improvement Projects. The act has granted local governments a legal basis to support residents participation activities in order to create, improve, and maintain the townscape quality of their neighborhood environments. The degree of utilization of this particular process, however, is far below the expectation. Partly, it is due to the lack of field experience and concrete guidelines for preparation and implementation in actual landscape planning process. This study aims to seek for detailed solution to lead the residents participation for local landscape improvement in Korea through consideration for institutional strategies and cases about the local landscape planning and management in Japan. Local landscape improvement projects in Japan are progressing successfully in concurrence with a variety of local participants such as residents participation, administrative supporting and supporting of local company. And it will be possible to support systematically with systematization of participants, such as NPO and a council.

  • The problems of agriculture and food production in Korea are serious. These problems were brought about by the global food system. In this system, farmers and consumers are disconnected. The distance between food production on the farm to the consumer's table is too long. Farmers can not survive as their food dollar is steadily decreasing. Consumers have to eat old, unclean, and poor-quality foods because the foods do not come from nearby farms. They do not know where their food has come from or by whom their food was grown. In order to solve these problems, the transition from the global food system to a local food system is imperative. In a local food system, farmers and consumers are connected and they can help each other. This study identifies the consumers' role in the local food system. They are the purchasers of local food. They are active participants both in producing and distributing local food, and in taking part in the local food movement. Above all, they are the teachers of the younger generation consumers. While consumers in the global food system are passive, those in the local food system are active. We call the former "food illiterates" and the latter "food citizens." In order to revitalize the local food system, consumers must be food citizens, and therefore, consumer education is necessary. There are several interdependent media forms available for consumer education such as field trips, farm experiences, education for returning to the farm, and food education.

  • We have investigated coarse wind sectors in Busan metropolitan area and simulated detailed wind field using local atmospheric circulation model, RAMS in preceding studies (Part I, Part II). In this study, we divided and analyzed local wind sector in Busan according to the preceding results. We found that Busan metropolitan area is divided into 2 or 3 local wind sector in each coarse wind sector. The 9 coarse wind sectors were classified into 20 local wind sectors in total. But three local wind sectors were finally excluded because of these sectors were located on the complex hill area and the sea. Local wind sectors, therefore, in Busan metropolitan area were defined as 17 regimes. We assessed the location of air qualify monitoring sites at Busan metropolitan area using the information of these wind sectors. Most of these were located at proper points, but 6 sites were placed at 3 local wind sectors as a couple and no site was set up at 3 other sectors. Hence the location of these sites was in need of rearrange.
