  • 본 논문에서는 유전알고리즘(GA)을 이용한 PID계수 자동조정기법에 관한 DC 서보 모터 속도 제어기 설계를 목적으로 한다. DC 서보 모터는 수많은 제어용 기계나 로봇 등의 응용분야에 사용되고 있고 이러한 분야에서 제어기 파라미터들의 선택이 사용자의 전문적인 지식을 요구하게 된다. 따라서 일반적인 공정 기술자들은 시행착오에 의해 제어기 파라미터들을 계속적으로 반복 조절해 나가야 한다. 이와 같이 동적 시스템의 변화나 외란에 대하여 파라미터 계수를 자동 조정해야 할 경우 유전알고리즘을 사용함으로써 보다 정밀하고 최적화된 파라미터 계수값을 추종함에 따라 그 성능을 높일 수 있다. 본 논문에서는 DC 모터의 동특성을 분석하여 얻은 동특성 모델링으로부터 응답 특성이 빠르고 속도 정밀도가 향상된 구동제어가 가능한 제어기를 설계하고 이를 PID제어기와 비교 평가하였다.

  • This paper explores the empirical performances of the workout companies with special interests in the effectiveness of corporate reorganizing tools on their revitalization. In the empirical analysis it considers the criteria of success or failure in restructuring from both creditors' and debtors' perspectives. The key results are summarized as follows. First, the initial conditions on the debt structure of the workout companies are significantly related to the revitalization from both creditors' and debtors' point of view. Second, the debt restructuring instruments are insignificant in the success of corporate turnarounds while the debt-to-equity conversion has been a relatively effective tool. Third, the self-restructuring efforts, employment downsizing and governance reshuffling do not affect the performances significantly. The higher importance of initial conditions than corporate restructuring efforts may imply that Korean corporate workouts serve better to the needs of creditor financial institutions which are to maximize debt recovery and of the government which is to overcome financial crisis.

  • There exist some limits when we forecast urban railway demand by traditional 4 step model. The first reason is that the model based on socioeconomic data by an administrative unit, 'Dong', yields a 'Dong' unit trip matrix. But a 'Dong' often has two or more stations. The second reason is that urban railway demand by station would be affected rather by station access area on foot than by a 'Dong' unit. So the model based on 'Dong' characteristic data have some inaccuracies in itself. Owing to the limits of the model based on 'Dong' unit data, there exits some difficulty in forecasting urban railway demand by station. So this paper studied two alternatives. The first is to forecast the demand by using the data of station access area on foot rather than 'Dong' unit data. This needs too much time and effort to collect data and analyse them, while the accuracy of the model didn't improve a lot. The second is to adjust the location of 'Dong' centroid and the length of centroid connector link. By this way we can reflect the characteristics of station access area on foot under traditional 4 step model. Comparing the expected demand to the observed data for each station, the result looks like very similar.

  • "老老恒言"是清代著名养生家, 文学家曹庭栋所著. 曹庭栋, 于乾隆38年(1773年), 他在75岁之时参考307种历代书籍, 并结合自己体验而写成了"老老恒言". 本书又栋"养生随笔", 其不但内容丰富, 而且涉及老年养生的各个方面, 是一部老年养生专著. 本论文对"老老恒言"中论述的老年人的消化器系统之养生法中心分析如下. 因为?着年龄增长, 老年人脏腑功能越来越衰退, 所以对于老年人来说脾胃系统机能是最重要的. 老年人要经常保持腹部的暖和, 及舒适. 老年人吃饭的时候, 饮食应该有所节制, 切忌饥饱失常或者夜餐. 老年人饭食宜清淡, 盐的摄入最好保持最低量, 宜调和五味而忌杂以他味或者偏嗜. 老年人宜先饥而食, 先渴而饭, 食当有度. 并且宜少食多餐而忌错过饭, 一觉醒来别就吃饭. 饭食之冷热, 应该顺从四时变化, 冬宜热食m 夏宜凉食, 但其温度宜适当. 而且食物宜完全地煮烂, 有利于消磨输运, 吸收营养. 进?食以后, 就不宜躺在床上或者走得过快, 宜悠悠地散步. 并且肚子饥饿时, 不得大呼大叫.总之,老年人在节制饮食, 调理脾胃的基础上, 要注意调和五味, 清淡饮食, 要先饥而食, 少食多餐, 要注意冷热适宜, 食贵烂煮,要做到食勿急行, 饥勿呼叫, 最重要的是选取食物时, 当以身体察, 各随禀气所宜而食之.

  • A modeling technique is proposed for dynamic simulations of OHC valve trains with HLA(hydraulic lash adiuster). HLA is expressed by an air-oil mixture model considering HLA leak-down and aeraton effects. A compact nonlinear equation is derived which describe the short term dynamic behavior of the HLA. Valve spring is analyzed by a distributed parameter model including nonlinear characteristics in the spring surge phenomena. Global behavior of the remaining valve train is expressed by a lumped mass model. The experiental results prove that the simulation model developed here is accurate and useful for the dynamic simulations of OHC valve trains with HLA.

  • Construction projects are being more complicated in proportion to the economic development. Process management is a critical issue in the construction that decides success of a project. Especially, a TACT method which divides and manages resources to repeat each activity is more important. Although becoming an issue dealing with the delay at winter season, it is not property developed. This paper suggests 'activity priority method' and 'TACT unit method' through case study. We validate necessity and efficiency of the TACT method through simulations and a survey. We expect cost reduction by decreasing unnecessary spending.
