The objective of this study is to provide direction for agricultural extension services in an age of localization. Agricultural extension services has carried out most of its activities by central direction and control. The central planning and management resulted in disappointment, inflexibility, and lack of responsiveness of the central bureaucracy. Facing localization in recent years, the extension system has not been satisfactorily developed to meet local demands. Korea has to choose to decentralize its extension services. The decentralization of extension services involves the transfer of planning, decision making, and management from the central government to the local level.

A recently developed alternative to traditional production planning and control systems such as material requirement planning(MRP) and just-in-time(JIT) is the drum-buffer-rope(DBR). The DBR now being implemented in growing number of manufacturing organizations enables better scheduling and decision making on the shop floor. In implementing the DBR, however, an information system is usually needed to transmit the signal that runs from the constraint to material release. In this paper we propose a different mechanism to transmit the signal in the case that the demand of product is stable, which uses the well-known Kanban system. To improve the reality, this paper shows and example of the Kanban format, its operation, and calculation of the number of Kanbans.

The main purpose of this paper Is to develop the Management Resource Analysis System for KOTRA which is based on Activity Based Costing(ABC). Because the products and services of KOTRA are exclusive and include a government subsidy, we need develop a different system from the private firm's ABC system. The Management Resource Analysis System that we propose is embodied using JAVA and JSP within an UNIX environment and developed as a Web-enabling base. It is expected for aiding a manager's decision-making such as resource inquiry, standard resource analysis, estimating the ratio of a government subsidy, case based reasoning, what-if analysis. The results of this paper suggest what points are to be considered when we apply ABC for Government Investment Corporation.

We had our share of success in the dental industry in 2009, but we also had our bits of problems. I regret that our still unsolved bits of problems were some of the more important issues in dentistry. We have tried our best with passion, but we faced many limitations. I hope in expectation, that we analyze these problems so that we may overcome them. I hope that the Korean Dental Association be equipped with valid evidence in decision making procedures corresponding to social justice, heighten our dentists pride by respecting the law and fulfill our duty as national oral health caretakers. The Korean Dental Association claims the goal as ${\AE}$Your Dentist, World Best, World Best Dentist with the people$^{\circ}\phi$ and the association should establish related policies and should be able to execute them. Also the association should be able to manage and execute the duties presented in the association regulations, thus, the importance of duty division according to profession must be emphasized.

내시경 초음파검사는 식도벽의 조직학적 층구조를 가장 유사하게 반영하는 검사법으로 식도 병변의 진단과 치료전략에 필수검사이다. 표재성 식도암에서 고주파 미세탐촉자를 이용한 EUS는 내시경 절제 같은 국소치료가 가능한 환자들을 선별하는 데 중요한 역할을 한다.

Selection of appropriate liner type would be the most important factor to prevent groundwater contamination by leachate from waste management site. This report introduces the IWEM (Industrial Waste Management Evaluation Model) developed by US EPA to evaluate the potential pollution of groundwater under the waste management unit and to suggest an appropriate type of liner, and provides with the results of IWEM application to a coal-ash landfill site in Korea as a case study. IWEM uses a standard method using a database, a decision-making process based on site characteristics, and the user-friendly input-and-output system. Authors evaluate this model to be applicable in Korea provided that the database is replaced into local data.

Cyber-attacks emerge in a more intelligent way, and various security technologies are applied to respond to such attacks. Still, more and more people agree that individual response to each intelligent infringement attack has a fundamental limit. Accordingly, the cyber threat intelligence analysis technology is drawing attention in analyzing the attacker group, interpreting the attack trend, and obtaining decision making information by collecting a large quantity of cyber-attack information and performing relation analysis. In this study, we proposed relation analysis factors and developed a system for establishing cyber threat intelligence, based on malicious code as a key means of cyber-attacks. As a result of collecting more than 36 million kinds of infringement information and conducting relation analysis, various implications that cannot be obtained by simple searches were derived. We expect actionable intelligence to be established in the true sense of the word if relation analysis logic is developed later.

The uses of drones are increasing despite the fact that many of us are still skeptical. In the near future, the data that will be created and used by them will be very voluminous, hence the need to find an architecture that allows good identity management and access control in a decentralized way while guaranteeing security and privacy. In this article, we propose an architecture using hyperledger fabric blockchain platform which will manage the identity in a secure way starting with the registration of the drones on the network then an access control thanks to Public Key Infrastructure (PKI) and membership service provider (MSP) to enable decision-making within the system.

Decoding the molecular mechanisms underlying axon guidance is key to precise understanding of how complex neural circuits form during neural development. Although substantial progress has been made over the last three decades in identifying numerous axon guidance molecules and their functional roles, little is known about how these guidance molecules collaborate to steer growth cones to their correct targets. Recent studies in Drosophila point to the importance of the combinatorial action of guidance molecules, and further show that selective fasciculation and defasciculation at specific choice points serve as a fundamental strategy for motor axon guidance. Here, I discuss how attractive and repulsive guidance cues cooperate to ensure the recognition of specific choice points that are inextricably linked to selective fasciculation and defasciculation, and correct pathfinding decision-making.

This paper deals with civil infrastructures in general, sensor and smart structure technology, and smart steel structures in particular. Smart structures technology, an integrated engineering field comprising sensor technology, structural control, smart materials and structural health monitoring, could dramatically transform and revolutionize the design, construction and maintenance of civil engineering structures. The central core of this technology is sensor and sensor networks that provide the essential data input in real time for condition assessment and decision making. Sensors and robust monitoring algorithms that can reliably detect the occurrence, location, and severity of damages such as crack and corrosion in steel structures will lead to increased levels of safety for civil infrastructure, and may significantly cut maintenance or repair cost through early detection. The emphasis of this paper is on sensor technology with a potential use in steel structures.
