The purpose of this study is to confirm the effects of the contents of the recording lectures through the automatic recording system of the nursing students on the program outcomes of the pediatric nursing. The study was designed using a nonequivalent control group pretest-posttest design. the subject of this study consisted of 104 nursing students(the experimental group of 52 and the control group of 52). Data were analyzed by ${\chi}^2$ test and independent t-test using SPSS 22.0. The effect of the first program outcome(PO1. We can integrate nursing skills based on various the liberal arts and the major knowledge into practice) of the experimental group was not confirmed, but the fifth program outcome(PO5. We can apply critical thinking based nursing processes and implement clinical inferences) was significantly higher than that of the control group. It is significant that this study presented the data to develop the class design method to improve the program outcomes of the nursing student at the present time which is operating the program outcomes based curriculum for nurse with core competency.

Although the use of NC machine is increasing in modern industry, unfamiliarities of the NC program syntax do not allow us to program it easily. So, automatic programming systems, such as APT, COMPACT, CL, were developed to help the uninitiated to write NC program easily. In this research, Korean Automatic Programming System for 2-axis NC lathe is developed, by which NC program is easily programmed using Korean letters. In addition, Graphic Debugger for 2-axis NC lathe is developed for debugging the NC program error and animating the cutting process. The above systems are run on the IBM-PC/XT.

Manufacturing is characterized by increasing product variety and technical complexity, decreasing levels of demand, expanding global competition and declining profitability of organizations. To survive in such a complex environment, development of the automatic design system into design and manufacturing can be introduced to increase the flexibility and adaptability to markets. This paper presents the development of an automatic water-gate design system that composed of a main program and three modules, and was programmed by AutoLISP language under AutoCAD system. The devel-oped system is capable of generating water-gate design automatically according to input data as customer requirement.

This paper presents a program for the automatic alignment of optical axes and evaluation of the optical filter performance which is a key technologies for the production of optical module. Recently the production of optical filter module mostly depends upon handwork or semi-automation. Moreover, they have used an expensive spectrum analyzer. In this work, we have developed an automatic alignment and evaluation program of optical filter module using photo detector and developed program for automation and cost reduction of the production of optical titter module.

In this study, a computer program was developed which generates automatically a drawing of the forging design in axisymmetric hot-forging of steel. The program designs a forging envelope from a machined part geometry according to forging design rules: parting line, draft angles, fillet and corner radii, minimum web and rib thicknesses. For the purpose of verification, the program was applied to a machined part from a factory. It was found that the generate forging design agreed well with the actual one used in the factory.

The design of sleeper in high-speed railway turnouts is complicated and time-consuming because the length and loading position of sleepers change continuously along the turnout line. It is, therefore, necessary to develop an automated design program which can design automatically the PSC sleepers in turnout region. In this study, a computer program for automatic design of turnout sleepers was developed based on graphic user-interface(GUI) environment. The structural analysis is performed considering the varying loading position of vehicular wheels. The sleepers are treated as located on elastic supports. The user can choose the desirable shape of sleepers before starting the detail design. The present study allows more realistic and automatic design of PSC sleepers in high-speed railway turnouts.

In this study, the peak stress of a fuillet in elastic structure was optimized to have minimum value by using quadratic isoparametric element. The method of auomatic gridding was also developed along with shape algorithm and design element technique was adopted in selecting design variables. The computer program developed was combined with the Hooke-Jeeves direct algorithm of optimization techniques in order to minimize the peak stress of the fillet. The imployment of design element technique significantly cut down computer time by the reduction in design variables, and the opitmum fillet shape with uniform minimum stress was obtained by varying design variables along x and y directions in improving the shape compared to other results. By using automatic gridding, in which Bezier surfaces and Coons surfaces of cubic interpolation were employed, the irregular boundary was removed resulting in smoother anbd more accurate fillet shape possessing uniform minimum stress.

In general, engineers have to consider a variety of factors in design of a structure. For this reason, it was difficult to make a design program up to now. But the rapid development of hardware and software turns it into a possibile one with considering complex factors and designing simple structures. When we use the design program including structural analysis, we can save time and cost to make calculations; report and drawing. In addition, the design program was developed to reduce the man made errors. Therefore, in this study, we try to develope the design program of the superstructure of P.S.C girder bridge and abutment. This program will provide engineers with time that they can spend on a creative and efficiency task for development of design.

For designing working devices of construction equipment, it is necessary to consider not only sufficient working ability but also available working range. Therefore, it is important to select the appropriate pivot positions of links. This paper presents a study on selection of pivot points of links used in construction equipment. To analyze the effect of each pivot point, a design program for pivot selection is developed. A conventional pivot design method requires a complicated process because it needs to create a certain working position manually to evaluate its performance. However, the developed program includes an automatic link assembly algorithm; thus, the working device can easily be analyzed by using pivot information of links. The developed program also included a kinematic/static analysis module and characteristic analysis algorithms. Therefore, it is possible to easily analyze a working device model created through the automatic assembly algorithm, whereby users can easily analyze the effect of each link pivot point for the actual product design.

This study is the election of optimum forming condition for RP system using ADS. Program using ADS reduces the required time for feedback between design and manufacturing of workpiece. When we produce rapid prototype using RP system, we investigate the relationship between Facetres in system variable number of AutoCAD and circularity of rapid prototype, and we will find optimum forming condition in RP system.
