  • Developed in this paper is a standard time data for shirt sewing operations in the apparel-making industry. Since this data is made of formula developed for each unit operation and includes the formula for the machine time calculation, users could use it for obtaining the normal or standard time without any special efforts. In addition, this data handles the variations due to the design changes of a shirt through the parameters in the formula. compared with the MTM-1. The standard time data developed is shown to be easier and faster in determining the standard time with acceptable accuracy.

  • A survey was conducted on 2,321 Chung Rhang Middle School boys to check out their physical growth, development and the number of parasite carriers during the period from June 16. to June 23. 1970 As the results of this study, the following conclusions were revealed. A) Physical Growth and Development State. 1. Direct curve in physical growth and development was observed during the period from 13 to 16 years of age. 2. The age and quantity of maximum growth and development. Height; 13~14 years of age 6.1cm Body weight; 14~15 years of age 5.1kg Chest circumference; 13~14 years of age 9.9cm Sitting height; 14~15 years of age 3.4cm 3. Comparison with Japanese students Most Korean students are shorter than Japanese students, though the standard of height became higher than before. The standard of body weight is visibly lower than Japanese students. The standard of chest circumference of the students of age 14 is higher than counter part of Japanese students and the all boys are lower than Japanese students except at the age of 14. The standard of the sitting heights of the Korean students are growing steadily, but every students are shorter than Japanese students. 4. The greatest differences in physical growth and development were shown in 13~14 years of age. 5. The students of 13~15 years of age developed their bodies most highly according to index of Rohrer. 6. Body weight and chest circumference have not grown enough compared with height. The development of sitting height was made highly and the development is steadily growing as they grow old. B. The Number of Parasite Carriers The number of parasite carriers was shown 79.4 per cent among all the student checked out. The number of trichuris was shown 79.7 per cent. The number of parasite carriers was shown higher per cent as the grow old.

  • BACKGROUND: Measurement equipment was developed for inorganic nutrient concentration inside the hydroponic culture medium with several macro- and micro compositions, and applied for measuring the compositions of conventional medium. METHODS AND RESULTS: Before the equipment development, sonicator and heater were utilized to control temperature around of the module mixing with color reagents and target samples among the inorganic compositions. The measurement module and multi-sampler were also manufactured based on the COMS (Complementary Metal-Oxide Semiconductor) and installed inside the measurement equipment. Concentration of standard solution, value measured by the equipment, standard deviation or measured average value were used for estimating the accuracy and average recall of the equipment. Yamazaki solutions with EC of 0.5, 1.5, and 2.5 dS/m were offered to confirm the equipment accuracy and standard error. CONCLUSION: It was suggested that the developed equipment could be automatically applied for measurement with accuracy of over 96% and standard errors of less than 5% on 12 macro- and micro compositions such as a NO3-N, PO43- or Fe.

  • In this paper, we propose a documentation case(before DAPA establishment) for weapon system development that defines development phases, documents which must be produced as a result of development, and relationship between those documents. To develop the documentation system, US DOD Standard, US Military Standard, and instructions of ROK MND are presented and analyzed in the point of standardizing documents. As a result, development phases and document case which is related to those phases are presented for weapon system development.

  • The objectives of the study were 1) to make the reasonable standard, 2) to select the objective and scientific method and process for the location-allocation of a new provincial capital city. The Main standard of location-allocation were suggested as follows ; 1) Integration of province 2) Convenience of Administration service 3) Accomodations of new provincial capital city 4) Balanced development by region. The validity of location-allocation were reviewed the population potentials and nodal accessibilities. The population potential was examined to find the maximum point of administrative demand, and the locationallocation model was examined to find the minimum point of the aggregated travel-cost to a proposed provincial government office. The nodal accessibilities measured in travel-time distance and actual values. Two major concerns in locating public facilities are efficiency and equity.

  • In this paper, we describe a method for precisely measuring the abrasion of the railway using an image processing technique. To calculate the wear of the rails, we provided a method for accurately matching the standard rail profile data and the profile data acquired by the rail inspection vehicle. After the lens distortion correction and the perspective transformation of the measured profile data, we used ICP Algorithm for accurate profile data matching with the reference profile extracted from the standard rail drawing. We constructed the prototype of the Rail Profile Measurement System for High-speed Railway and the experimental result on the three type of the standard rail used in Korea showed the excellent profile matching accuracy within 0.1mm.

  • National Competency Standard(NCS) is a national organization that organizes the knowledge, skills, and quality required to perform duties at industrial sites by industry sector and level. As NCS was developed and adopted as part of the government's implementation of capability-oriented society, the construction industry is also fully applying NCS to the curriculum and training. This study investigated and analyzed the problems of NCS development in construction work field through prior research analysis and experts interview and derived problems such as discrepancies in classification system, lack of connectivity with curriculum, and lack of effectiveness in revising NCS in construction work field. Further research is thought to be necessary for the establishment of the development system reflecting the construction characteristics in the future and for the presentation of practical improvement directions.
