The Purpose of this study is to enhance the efficiency of clothing-making units in the textbook of Home Economics for the high school students. I handed out a research paper with several questions to 75 teachers and 87 students to find out the realities of the education. There are several problems of making clothes at class: lack of time, appropriate equipment and efficient learning material. To solve these problems. I made a half-sized skirt kit utilizing OPTI Tex. a type of CAD in fashion design and copied it by silkscreen. and let the students use it. Both of the teachers and students showed positive response to the newly made kit of my own. saying that \"it is very handy to prepare and it\`s very helpful to figure out how to make skirt. \" Using the kit. we could reduce the time to make clothes by about 60 % and do well in the classroom without any sewing machines.

A new floating power supply for the current measurement system of a high voltage power line is developed. It is confirmed that, the current measurement system can stably transfer the signal of the power line current about 50 - 300 A by using the proposed power supply. The excellent characteristics are obtained by the steady-state and transient experiments of the proposed circuit. $\textbullet$ The right figure shows the external view of the trial measurement system for 6.6 kV. In order to see the inside, 120 degrees of the insulator is cut. The toroidal coil for the power supply and the Rogowskii coil for the current sensor are both divided into two and fixed on the power line as...$\textbullet$ The proposed circuit can supply +5V and -5V voltages without using a solar cell and/or a battery.

An examination of avalable data relevant to several problems in the Korean family planning program led us to the following conclusions: 1. The high incidence of discontinuance in the use of IUD appears to be one of the foremost problems which effectiveness of the family planning program in Korea. Thus, the development of technologies and program strategies to decrease the discontinuance rate is badly needed to increase effectiveness and efficiency of the program. 2. The monthly supply of oral pill was found inadequate in terms of timing at the end and beginning of the year. 3. The frequency of home visiting showed discrepancy between service statistics and survey result. Evidences indicate that the latter figure is more correct. Program strategies should be developed to make home visiting activities more effective. 4. It was observed that the unit cost of the family planning program was increased fairly rapidly. It calls for the necessity of increasing cost efficiency of the program.

In this paper, It does the profile measurement of the cam of diesel engine SOHC of the actual object. It uses the measurement of run-out method. This method is that the surface of the object is measured by the sensor when the object rotate, and calculated and displayed by the computer the signal which acquired by sensor. When we acquire the signals, we have two error because of motion and contacting between cam and probe. In this paper, we compensate the motion error while simply liner equation. And we have a solution that we change the figure of probe when we have a contacting error. We compared the data measuring on developed automatic cam profile measuring system with the data measured on CMM.

An E-OPMT(Electronically-controllable OPMT) was developed as an alternative of OPMT which could adjust the direction of the generated guided waves in a plate manually. The key idea of controlling the wave direction electronically is based on a few sets of axisymmetric figure-of-eight coils and the magnet which is located for making static omni-directionally biasing magnetic field over the patch. However, in order to explain wave phenomenon generated by this transducer, a new approach is required because there are various combinations between static biasing magnetic field and dynamic actuating magnetic field on the patch, not similar to OPMT. In this paper, the experiments were performed to understand characteristics of E-OPMT and the new theoretical analysis was set up for explaining the result.

The main project of the village mini-library movement is to establish and guide mini-libraries in the rural villages in Korea since 1961 in order to promote reading campaign. The purpose of this study is to examine into early developmental process of Korean mini-library movement from the formative period to 1967. Therefore, this study analyzes the principles of this movement, the policies for rearing mini-libraries, financial accommodation and the performance of this movement in 1960's. The study, in final, reviews the overall figure of the early process of this movement in Korea.

Beauty of balance, can be found in antique furniture of the Joseon Dynasty. Balance, give comfort and peace of mind to people. Even today, the balance in various fields, it is easily viewed, and an important one element indispensable in the design. Various lighting is an essential element of the interior to create an atmosphere of space. It is also useful in a variety of ways for beauty, emotional effect, such as the switching of visual atmosphere. This design was designed with the concept of balanced. In addition, I have applied a simple graphic appearance. To give the fun and tension while giving it a well-balanced when you meet the figure. The design of this study is nothing more than a single direction. It will be in the traveling direction of the future as a designer by using a simple structure and phenomena that appear in life, is given to the design without the feeling of rejection to the user.

The Internet is one of the most infrastructure for information technology in school education. Providing the Internet with a proper bandwidth is an important element for efficient school education for information technology, especially because several instructional models based on new Internet technologies are under development. To support these instructional models, it is important for the schools to provide the proper Internet bandwidth wherever necessary. In this paper, the amount and pattern of internet usage in school were analyzed. Based on this analysis, we propose how to figure out a proper bandwidth for a different ladder of schools.
