The detection of tubercle bacilli (TB) from sputum smear is one of the fast and inexpensive methods for diagnosis of tuberculosis. For this method. sputum smears are usually flexed by heating and stained by acid-fast staining method, and then examined under an optical microscope. Two Procedures are commonly used fur TB staining. One is hot staining and the other is cold staining method. The Ziehl-Neelsen method which is a hot staining method is widely used in Korea because its stained color is more vivid However, the conventional automated stainer has to fix the sputum smear on a slide manually and the stain is not so vivid because it has not heating function. In an effort to save labor and minimize variations in manual staining Procedure. we developed an automated stainer with heating function. The entire staining process is fully automated. from fixation to final washing and drying. With the automated methods, five slides can be flexed and stained in 21 minutes at consistent high quality We compared the concordance rate between the two methods for 91 sputum samples to validate the stain quality of the developed automated stainer. As the results, the concordant rate between the two methods was 95% and there was no significant difference (p>0.05)

Remarshalling operation is one of the operations considered important in an automated container terminal to perform quickly loading operations and delivery operations. It arranges the containers scattered at a verticla yard block in order to reduce the transfer time and the rehandling time of ATC(Automated Transfer Crane)s. This paper deals with the remarshalling planning problem minimizing the weighted operation time. This problem can be decomposed into 2 subproblems, storage space assignment problem and operation sequencing problem Storage space assignment problem decides to where containers are transported in terms of transportation time cost.. With results of a previous subproblem, operation sequence problem determines the ATC operation sequence, which minimizes the dead-heading of ATC This study formulates each subproblem with mixed integer program and dynamic program. To illustrate the proposed model, we propose an instance to explain the process of remarshalling planning.

Purpose: The purposes of this study were to develop and examine the self-help and Tai Chi program for arthritis, and to identify the effect when combined with a supportive follow up phone-calls. Method: The design for this study was a 3*2 quasi-experimental design. Sixty-six participants were recruited in W-city, and assigned to Exp 1 group (n=21) or Exp 2 group (n=24) according to supportive follow-up phone call method, or to the control group (n=21). Fifty-two subjects (17 and 20 in Exp 1 and 2, and 15 in the control group) completed pretest and posttest. Both experimental groups participated in the self-help and Tai Chi program for arthritis once a week for 8 weeks. Exp 1 received automated follow up phone-calls made up in KT-SHUT program, and Exp 2 received follow up phone-calls made up by researchers. The control group received no education and no phone call. Measures used to examine the effect self-help and Tai Chi program for arthritis were joint flexibility, hand muscle strength, balance with closed eyes and self-efficacy. The final analysis of the post-test measures was conducted by ANCOVA with age and self efficacy as covariates. Results: Both experimental group had significantly increased right shoulder flexibility (p=.002), left shoulder flexibility (p=.000), right hand grip (p=.024), and self efficacy (p=.008) compared with the control group. But there were no significant differences between two experimental groups in any physical indicators and self efficacy. Conclusion: Automated follow up phone-call would be helpful in managing the self-help and Tai Chi program for arthritis as well as researcher's phone call. The automated follow up phone-call program which was a new method could be recommended for use to encourage home exercise practice and the program participation.

The purpose of this paper is to strengthen trust on the automated collaborative filtering system. Automated collaborative filtering system is quickly becoming a popular technique for recommendation system. This elaborative methodology contributes for reducing information overload and the result becomes index of users' preference. In addition, it can be applied to various industries in various fields. After it collaborative filtering system was developed, many researches are executed to enhance credibility and to apply in various fields. Among these diverse systems, collaborative filtering system which uses Pearson correlation coefficient is most common in many researches. In this paper, we proposed new process diagram of collaborative filtering algorithm and new factors which should improve the credibility of system. In addition, the effects and relationships are also tested.

Mesh generation for the region of interest is prerequisite for numerical analysis of governing partial differential equations describing phenomena with proper physic. Mesh generation is, however, usually considered as a major obstacle for a routine application of numerical approaches in Engineering applications. Therefore automatic mesh generation is highly pursued. In this paper automated quadrilateral surface mesh generation is proposed. According to the present method, Cartesian cells of proper resolution for a region bounding the whole region of interest are first generated and the interior cells are identified. Then projecting their surface meshes onto the boundary surfaces gives surface mesh consisting of quadrilateral cells. This method has been implemented as an application program, and example cases are given.

There is a worldwide trend to automate the handling operations in port container terminals in an effort to improve productivity and reduce labor cost. This study iscusses how to apply an AGV(automated guided vehicle) system to the handling of containers in the yard of a port container ter-minal. The main issue of this paper is how to assign tasks of container delivery to AGVs during ship operations in an automated port container terminal. A dual-cycle operation is assumed in which the loading and the discharging operation can be performed alternately. Mixed integer linear program-ming formulations are suggested for the dispatching problem. The completion time of all the dis-charging and loading operations by a quayside crane is minimized, and the minimization of the total travel time of AGVs is also considered as a secondary objective. A heuristic method using useful properties of the dispatching problem is suggested to reduce the computational time. The perfor-mance of the heuristic algorithm is evaluated in light of solution quality and computation time.

This paper analyze the dynamic characteristics of Automated Guided Vehicle(AGV) which is being developed as a part of automation in port through DADS, one of the multi-dynamic analysis program, Previous evaluation of a vehicle is carried out through the continuous driving test of a real vehicle, however this method raise the loss of finance and time. If it is possible to analyze the dynamic characteristics of vehicle before construction completely we can compensate the loss of money and time during constructing. AGV contained containers is very heavy and its center of gravity can be easily changed with the disturbance from road or cornering. It makes AGV unsatisfied, therefore we evaluate the handling characteristics and stability of the full vehicle model. This paper contribute to establish the foundation of the development of a new system like a AGV which have a special structure.

Automated sequencer로부터 얻게된 서열은 PCR이나 sequencing의 영향 등으로 기존의 자료 또는 분자생물학자가 원하는 서열과는 조금씩 차이점을 나타내게 되고, 이를 보정하기 위해 수작업으로 처리하게 된다. 이는 아주 간단함 작업임에도 불구하고 30분에서 1시간, 많게는 몇 시간씩 걸리는 불편함을 감수하고 있다. 본 논문에서는 분자 생물학자들이 효율적으로 서열을 분석하게 하는 sequence finishing program의 구현에 관하여 논의하였다.

In this paper, we developed an automated program for the modeling and manufacturing of three-dimensional roller gear cams. A computer program employing the theory of gearing and coordinate transformation is developed for synthesizing and animating cam mechanisms. Then a module for generation NC program for a five-axis CNC machine to manufacture roller gear cam is established.
