In most shipyards, the measurement of 3-dimensional relative position of pipes should be connected in the block depends on the manual operation. It results a very tedious and inefficient procedure, thus the proper measurement system is needed to improve productivity and accuracy. This paper describes the development of pipe measurement system including system concepts, measuring procedures, system calibration, and its accuracy and productivity. And also, the possibility and things to be improved for application in shipyard are discussed in this paper.

Bootstrap approximation is compared with ordinary asymptotic method in the context of minimum chi-square estimation through application in a real problem. Fixed interval search method is shown to be superior over a random interval search method or Newton-Raphson method. All the procedures are implemented by S-Plus functions.

In Korea, farming population is rapidly decreased in each decade. Consequently, farming is becoming more complex with multi cropping, animal production and green house farming. In order to encounter this complexity of farming, expert system applications on diagnosis, planning, designing, management, control, and training are demanded to meet the needs of agricultural society. In this article, expert system establishment procedures are stated step by step and extensive literature review was conducted on the expert system development techniques.

This paper treats the problem to schedule for train with low transit priority so as to maximizing the number that can be sent during given time without interfering with the fixed schedule for train with high transit priority in a track. We transform the this problem into Time-Expanded Network without traverse time through application of Ford-Fulkerson Model, develop a TENET GENerator(TENETGEN) and obtain the data of TENET using developed TENETGEN. Finally, we seek the optimal solution to these data with Dinic's Maximal-Flow Algorithm and examine the availability of our procedures in personal computer.

A new finite element technology based on p-version of F.E.M. is discussed with reference to its potential for application to stress intensity factor computations. In linear elastic fracture mechanics, especially cracked cylindrical shells. It is shown that the p-version nutlet is far better suited for computing the stress intensity factors than the conventional h-version models with the help of three test problems. The main advantage of this technology is that the accuracy of approximation can be established without mesh refinement or the use of special procedures.

We have been recognize the adaptation of JIT(Just-in-Time) production system is necessary to improve the constitution of enterprises. But this system is not settled in our industrial environment owing to misunderstanding of JIT concepts and lack of participation all members of the oranization. This paper deals with systematic application of the JIT subsystems such as U-form layout, flexible workforces with multi- functional skilled workers and adjustment of standard operations procedures. And a successful productivity improvement case study of a small and medium sized industry was dealt.

Detailed finishing of the occlusion is a clinical skill that has become difficult with the development of fixed appliances. Accuracy of bracket placement definitely improves with indirect technique, Several methods for the placement of orthodontic brackets on dental casts are currently used in the indirect bonding technique. These include attachment by means of bonding resins, adhesive tapes or sticky wax. This article presents the indirect procedures of our clinic, which use paste-paste chemically cured composites. Detailed laboratory and clinical procedure for dual tray method and other application of indirect bonding will be presented.
