The objectives of the study are to identify the issues and problems encountered in Korea's current integrated rural regional development(IRRD) program and to suggest policy remedies to cope with them. Secondary data and materials ate mainly used for the study. Since the mid-1980s, rural settlement planning has been carried out in the Republic of Korea, In the planning process,'scale of economy'perspectives and settlement policy have been emphasized for increasing the efficiency of investment. During the 1990s, rural settlement and major village development projects have been implemented under the rural structure transformation programs. Agricultural structure adjustment projects for land consolidation and sizable farming have been separated from the rural settlement and mojor village development projects. Based on the evaluative analysis for the rural structure transformation policy and program, some problematic issues were raised as follows: (a) lack of integrative control function in the program'(b) weak linkage between living environment improvement and agricultural development projects: and (c) lack of comprehensive village development planning and implementation system. The policy issues to solve the problems were suggested as follows: (a) adoption of bottom-up approach in new IRRD planning and project system : (b) projection of comprehensive development planning and project at the village level; and (c) introduction of new regional agriculture development projects such as direct payment system for farming in less favorable areas and organic farming.

This paper is in the intersection of software engineering and system engineering, two intimately intertwined disciplines. A dominating theme in this paper is the integral conceptualization of systems at large, as well as an underlying concern with software systems. In the software development life cycle, challenges still exist in translating requirements into a design artifact and then into an implementation (e.g., coding), then validating the results. From our perspective, software engineering requires an integrating paradigm toward a unified modeling orientation. Many methodologies, languages, and tools exist for facilitating system development processes. This paper is a venture into project development. To focus the materials, we concentrate on Harel's novel (and classic) development environment, which integrates a scenario-based engineering object orientation and statecharts through developing a railcar system. The railcar system is used as a detailed sample of translating requirements into a design artifact and then into an implementation, then validating the result. The project is re-cased as a single integrated modeling endeavor to be contrasted with the scenario and statecharts' development. The result of this scheme is an enriched understanding through experimenting with and contrasting various development methods of software projects.

According to the report of the Korea Agro-Fisheries and Food Trade Corporation (2019), the size of the HMR food market in 2019 exceeded 4 trillion won. On the other hand, the consumption of agricultural products continued to decrease. As reported by Woo (2020) who analyzed consumer panel survey data, when the 2010 agricultural product purchase index was 100, the crop purchase index in 2019 was 72 and the vegetable and special crop purchase index was 69. Therefore, the Rural Development Administration promoted the research projects to develop the technologies for producing stably raw materials of HMR and for optimizing local foods as HMR ingredients. Researches on the development of HMR using local agricultural products has been being promoted in Cheonan, Chungju, and Jeju in 2020. In the case of Jeju, it has been prepared and realized the B2B commercialization of Jeju agricultural products in connection with the convenience store ingredients supplier in the province. In the case of Cheonan, development of HMR foods like as Sundae, dumpling, sausage, and Tteokgalbi using willd chive, cherry tomatoes, shiitake mushroom, fortified perilla, and licopene fortified watermelon has been being promoted. Lastly, in the case of Chungju, a diverse HMR foods have been developed using beans, centella asatica, Japanese lady bell, apples and peaches such as blended juices, frozen boiled rice, and tofu kit. In the future, in connection with the regional specialized crop cultivation project promoted by the Rural Development Administration, we intend to support the convergence commercialization of R&D technology based on regional characteristics.

The use of the sustainability rating systems in infrastructure construction projects is not as common in comparison to building construction projects. While the sustainability rating systems share some commonalities, they differ from one another in certain ways. Thus, project teams cannot make reliable decisions when choosing the best sustainability rating tools for a given infrastructure projects. The Department of Transportation (DOT) in several states are developing its own rating system to address the infrastructure sustainability, but not in the case of California. Therefore, this paper presents the statistical results on the important sustainability determinants that affects the success of meeting sustainability goals of infrastructure construction projects. The authors conducted an online survey using the structured questionnaires. The categories considered include site, water/wastewater, energy, materials/resources, environmental, and others. The statistical analyses such as Kruskal-Wallis and ANOVA are conducted using a total of 25 valid and complete data out of 59 surveys collected. The results demonstrate several factors under each of six major sustainable categories have received higher ranks than other factors. The results also show that a statistically significant difference can be found from water, energy, and environmental categories against the other category based on the pairwise comparisons.

Existing improvement measures for resource management are merely concentrating on the document automation only. In addition, such improvements rarely benefit metal millwork management. Following the trend of constructing high rise and multi-complex buildings, the importance of resource management from the aspect of construction project management is being emphasized. Metal work resources are critical most of construction projects, it became a target for special management. Therefore, the study has determined work process of metal work resource management, for the metal millwork is one of the most important construction materials most of construction projects, and proposed a web based module for improving the management task.

In April 2001, many Japanese national institutes were reorganized as Independent Administrative Institutions (IAI) based on the General Act for Independent Administrative Institutions and the act for each institution. Under the Ministry of Education, Culture, Sports, Science and Technology (MEXT), the National Institute for Materials Science (NIMS) was established by the merger of the National Research Institute for Metals (NRIM) and the National Institute for Research in Inorganic Materials (NIRIM). One of the biggest changes was the expansion of autonomous administration. The nanotechnology and material R&D field was prioritized in the 2nd (2001-2005) and the 3rd (2006-2010) Science and Technology Basic Plans; subsequently, NIMS was assigned to take the initiative in nanotechnology as well as materials science. NIMS has proactively expanded research fields through the introduction of researchers from polymers, electronics, and biotechnology as well as member institutes of the World Materials Research Institute Forum (WMRIF). Globalization has been promoted through programs that include the International Center for Young Scientists (ICYS) and the International Center for Materials Nanoarchitectonics (MANA). The 4th Science and Technology Basic Plan (2011-2015) emphasizes outcomes-recovery and rebirth from the disaster, green innovation, and life innovation. The Midterm Plan for NIMS also follows it. R&D collaboration by multi-partners (that include industry, university, and GRI) should be strategically promoted where GRI are especially required to play a hub function for innovative R&D and open innovation. NIMS highlights are Tsukuba Innovation Arena (TIA) and the Nanotechnology Platform Project. On January 20, 2012, a new organization was decided on by the Japanese Government where several IAI from different science and technology areas will be merged to realize more effective R&D as well as administrative cost reductions. NIMS is also supposed to be merged with 4 other R&D IAI under MEXT by the end of 2013.

Choosing the best-performance materials is a crucial task for the successful completion of a project in the construction field. In general, the process of material selection is performed through the use of information by a highly experienced expert and the purchasing agent, without the assistance of logical decision-making techniques. For this reason, the construction field has considered various artificial intelligence (AI) techniques to support decision systems as their own selection method. This study proposes the application of a systematic and efficient support vector machine (SVM) model to select optimal exterior materials. The dataset of the study is 120 completed construction projects in South Korea. A total of 8 input determinants were identified and verified from the literature review and interviews with experts. Using data classification and normalization, these 120 sets were divided into 3 groups, and then 5 binary classification models were constructed in a one-against-all (OAA) multi classification method. The SVM model, based on the kernel radical basis function, yielded a prediction accuracy rate of 87.5%. This study indicates that the SVM model appears to be feasible as a decision support system for selecting an optimal construction method.

This article describes the development of a fiber optic accelerometer based on Fiber Bragg Gratings (FBG). The accelerometer utilizes the stiffness of the optical fiber and a lumped mass in the design. Acceleration is measured by the FBG in response to the vibration of the fiber optic mass system. The wavelength shift of FBG is proportional to the change in acceleration, and the gauge factor pertains to the shift in wavelength as a function of acceleration. Low frequency version of the accelerometer was developed for applications in monitoring bridges. The accelerometer was first evaluated in laboratory settings and then employed in a demonstration project for condition assessment of a bridge. Laboratory experiments involved evaluation of the sensitivity and resolution of measurements under a series of low frequency low amplitude conditions. The main feature of this accelerometer is single channel multiplexing capability rendering the system highly practical for application in condition assessment of bridges. This feature of the accelerometer was evaluated by using the system during ambient vibration tests of a bridge. The Frequency Domain Decomposition method was employed to identify the mode shapes and natural frequencies of the bridge. Results were compared with the data acquired from the conventional accelerometers.
