현재 국내에서 많은 농가가 이용하는 경영진단방법 중 하나는 농촌진흥청 농업경영정보시스템 내의 농가경영컨설팅시스템에서 사용되는 경영표준진단표로, 진단결과는 DB화하여 농가경영컨설팅을 위한 자료로 활용되고 있다. 하지만 연도별 농가경영 진단결과 DB화 실적을 살펴보면 매년 실적이 조금씩 감소함을 알 수 있는데, 경영진단을 하는 농가 수의 감소는 농가가 경영진단을 통한 실질 효과가 기대에 미치지 못하였거나, 지속적으로 진단할 필요를 느끼지 못하는 등의 불만족 요인이 있음을 알 수 있다. 이러한 맥락에서 농가의 다양한 유형과 규모를 포괄하여 쓸 수 있는 컨설팅 기법의 개발과 실증사례의 발굴이 절실하다. 본 연구는 기존의 농가 중심의 농업경영체 경영진단 및 컨설팅 방법에서 부족한 요소들을 보완하고 기업형 농업경영체에도 적용이 가능하도록 경영전략 이론에서 사용되는 다중조직이론과 가치사슬모형을 적용한 경영진단 및 컨설팅기법을 소개한다. 다중조직이론 기반의 컨설팅 기법의 특징은 농업경영체의 경영전략은 크게 효율성추구와 효과성추구의 두 가지 방향이 있으며 경영체의 하부요소들이 경영 전략의 방향과 일치하는 방향으로 적합성(fit)을 맞추도록 하는 것이 특징이다. 즉, 경영체의 전략적 방향에 맞는 경영활동이 중요하며 이를 통해 한정된 자원의 분배를 최적화할 수 있게 된다. 제시된 컨설팅 기법은 농업현장의 경영체들에 실제로 컨설팅을 수행하여 현장실증한 사례를 보여줌으로써 컨설팅 기법에 대한 이해를 높일 수 있도록 하였다.

The objective of the proposed study is to produce a tool-condition monitoring (TCM) strategy that will lead to a more efficient and economical drilling tool usage. Drill-wear monitoring is an important attribute in the automatic cutting processes as it can help preventing damages of the tools and workpieces and optimizing the tool usage. This study presents the architectures of a multi-layer feed-forward neural network with back-propagation training algorithm for the monitoring of drill wear. The input features to the neural networks were extracted from the AE signals using the wavelet transform analysis. Training and testing were performed under a moderate range of cutting conditions in the dry drilling of steel plates. The results indicated that the extracted input features from AE signals to the supervised neural networks were effective for drill wear monitoring and the output of the neural networks could be utilized for the tool life management planning.

The information with regard to the working range of lathe, cutting tool, cutting condition is managed as Database system for turning operation as one part of CAM system. Data with regard to the working range of lathe, cutting tool, cutting condition are stored by the DBMS(Data Base Management System) and can be added, modified, deleted and retrieved for realtime usages. Data stored in Database system are searched to select the most proper cutting tool and cutting condition with the input data fed from the design stage. Codes in regards to tool shape are displayed on graphic mode for easy selection for user and thus presents a good decision support for tool selection. The system developed in this work is operated by the pull down menu on the IBM PC/AT personal computer, or compatible series.

The majority of programming education in the learning place attaches importance more to grammar, memorization of the imperative sentence and explanation of the program language itself than the specific way to use the target language. In addition, it is mainly used to teach theoretical knowledge based on the text. Consequently, current programming education has not interested learners in the programming learning and has not improved their ability in programming problems of the real world. We therefore developed a learning tool of C-language, which is based on the Console Wrapper. The purpose of proposing the learning tool was to make the programming education break from the typical theoretical learning and to let learners be interested in the programming education. By using the dynamic screen instead of the static console screen, the learners could enjoy learning the program. As a result of this study, we could know that the programming education using our learning tool is more effective than the typical C language programming education.

Few studies on the biomechanical analysis of hand postures and tool handling tasks exist because of the lack of appropriate measurement techniques for hand force. A measurement system for the finger forces and joint angles for the analysis of manual tool handling tasks was developed in this study. The measurement system consists of a force sensing glove made from twelve Force Sensitive Resistors and an angle-measuring glove (Cyberglove$^{TM}$, Virtual technologies) with eighteem joint angle sensors. A biomechanical model of the hand using the data from the measurement system was also developed. Systems of computerized procedures were implemented inte- grating the hand posture measurement system, biomechanical analysis system, and the task analysis system for manual tool handling tasks. The measurement system was useful in providing the hand force data needed for an existing task analysis system used in CTD risk evaluation. It is expected that the hand posture measurement developed in this study will provide an efficient and cost-effective solution to task analysis of manual tool handling tasks.s.

The aim of this study was to present a framework for clinicians to use when discussing electronic cigarette (e-cigarette) use and its association with pre-diabetes. A communication tool was designed using evidence-based strategies from the academic literature. A four-step framework is presented, which includes: step (1) helping patients to understand the association between e-cigarette use and pre-diabetes; step (2) the synergistic health impacts of e-cigarette use and pre-diabetes; step (3) management of diabetes-related lifestyle factors; and step (4) stages of change assessment related to e-cigarette reduction. This communication tool provides support for clinicians to discuss the risk of pre-diabetes associated with e-cigarette use. Moving forward, implementation and evaluation of this model are needed.

Interest is growing in applying simulation models for the South Texas conditions, to better assess crop water use and production with different crop management practices. The Environmental Policy Integrated Climate (EPIC) model was used to evaluate its application as a decision support tool for irrigation management of com (Zea mays L.) in South Texas of the U.S. We measured actual crop evapotranspiration (ETc) using a weighing lysimeter, soil moisture using a neutron probe, and grain yield by field sampling. The model was then validated using the measured data. Simulated ETc using the Hargreaves-Samani equation was in agreement with the lysimeter measured ETc. Simulated soil moisture generally matched with the measured soil moisture. The EPIC model simulated the variability in grain yield with different irrigation regimes with $r^2$value of 0.69 and root mean square error of $0.5\;ton\;ha^{-1}$. Simulation results with farm data demonstrate that EPIC can be used as a decision support tool for com under irrigated conditions in South Texas. EPIC appears to be effective in making long term and pre-season decisions for irrigation management of crops, while reference ET and phenologically based crop coefficients can be used for inseason irrigation management.
