Western clothing is adjusted to the figures of the human body unlike Korean traditional clothes. For this adjustment, we need a method, known as dart, to reasonably adjust a wide circumference to curves of the human body. So far, there has been some research in the aspect of clothing engineering on how to decide darts of skirts or trousers, but no theoretical research has yet been conducted on how to decide the number and amount of dart, which has caused difficulties in beginners' understanding of dart. Futhermore, there is no consistent drawing method for the number and amount of darts in existing teaching and teaming materials. Therefore, to develop teaching and teaming methods for darts, this study identified the amount and number of darts for waist girth of 66-72cm and a hip girth of 86-102cm. When the difference between the waist girth and the hips girth, including margins, is above a minimum of 26cm, two darts can be designed, but when the difference is below 24cm, one dart is necessary. The amount of darts increases by 0.5cm for every 2cm increase of the hip girth to the waist girth. In addition, as darts become longer, the cutting of the waist line becomes smoother. For one, rather than two, darts the curve of the waist line is steeper. Based on the above results, it was assured that when belts are curved through adjustment to the waist line of skirts or slacks, their composition can be stable. Therefore, in basic teaching about slacks and skirts, the number and amount of the darts should be designed according to the difference between the girths of the waist and the hip. This difference should be a minimum of 24cm, but if it is below 24cm, the number of darts needed is one.

The method of moments is applied to numerically compute the electrostatic capacitance of a parallel-plate rectangular capacitor of finite area. Each plate is discretized into 900 patches per unit area to ensure a high accuracy of computation. To further enhance computational results, the impedance matrix elements are additionally evaluated in the case that the observation patch is located above or below the source patch in the vertical direction. To examine the fringing effect at the edges of the capacitor, the normalized capacitances are computed as a function of separation distance. After these results have been verified by Palmer's formula, this method is extended to the computation of capacitances between two different size plates.

In this paper, we investigated the flow of an incompressible viscous fluid past a sphere which is oscillated one-dimensionally over flow regimes including laminar flow at Reynolds number of 100, 200 and Strouhal number of up to 5000. In order to analyze flow and estimate critical Strouhal number, we introduce three-dimensional vortex element method. With this method, separation only appears in decreasing velocity region during the high Strouhal numbers. We find out that vorticity distribution around sphere is proportionl to the Strouhal number. And we can decide that low Strouhal number is below 100, high Strouhal number is above 500 from many results. Thus the critical Strouhal number(St) effected to the flow field is expected to be 100

In this paper, vacancy clustering formation and diffusion of germanium substrate was studied. The analysis method was adopted Monte Carlo method. At temperatures higher than melting point, fewer clusters formed, but there was less variation in the number of clusters than at lower temperatures, as the time increased. Equilibrium diffusivities in the clustering region were $10^2$ lower than those of free vacancies in the initial stage of kinetic lattice Monte Carlo simulations. They were expressed according to three temperature regimes: at temperatures above 1,100 K, at temperatures of 1,100-900 K, and at temperatures below 900 K. The effective mean migration energy, 1.1 eV, closely coincided with that of the 1.0-1.2 eV in experiments.

This study was conducted to find the shortest optimum time for taking oral temperature and axillary temperature, which does not affect reliability of body temperature. For this purpose, first, the time at which all the samples are reaching maximum temperature is identified Second, the mean maximum temperature is compared with the mean temperature of each consecutive measurement by T-test to find the time at which no significant changes in temperature occurs along time sequence. Third, optimum temperatures are set at points of -0.2℉, -0.4℉, -0.6℉, -0.8℉, -1.0℉, -1.2℉, -1.4℉, from maximum temperature. A point of time at which 90% of samples reach at optimum temperature is identified and defined as optimum time. The study sample, a total of 164 cases were divided into two groups according to their measured body temperature. The group with body temperature below 37 $^{\circ}C$(A group) and above 37$^{\circ}$1'C (B group) were compared on the time required to reach maximum temperature and optimum temperature. The results are as follow. 1. The time required for total sample to reach maximum temperature was 13 minutes in both groups by oral method, 15 minutes in A group and 13 minutes in B group by axillary method. Time required for 90 % of cases reach maximum temperature by oral method was 10 minutes in both group. By axillary method, 12 minutes in A group. (Ref: table 2) 2. Statistical analysis by means of T-test, the time which does not show a significant change by oral method were 12 minutes in A group and 11 minutes in B group, and by axillary method 14 minutes in A group and 11 minutes in B group. (Ref: table 5, 6.) 3. Where optimum temperature was defined as maximum temperature minus 0.2 ℉, optimum time was found 8 minutes in both groups by oral method, and 11 minutes in A group and 9 minutes in B group by axillary method 4. Where optimum temperature was defined as maximum temperature minus 0.4 ℉, optimum time was found 7 minutes in A group and 6 minutes in B group by oral method, and 9 minutes in A group and 7 minutes in B group by axillary method 5. Where optimum temperature was defined as maximum temperature minus 0.8 ℉, optimum time was found 6 minutes in A group and 6 minutes in B group by axillary method (Ref: table 7, 8, 9, 10) 6. The commonly practiced temperature taking time, 3 minutes in oral method and 5 minutes in axillary method can be accepted as pertinent when physiological variation of body temperature at the mean level of -1, 2 ℉ is accepted. 7. The difference in time required to resister maximum temperature was compared between the group with body temperature below 37$^{\circ}C$ and above 37$^{\circ}$1'C, and found no significant difference in oral mettled and 1 - 4 minute difference in axillary method with shorter time requirement in feverish group.

This is the report of a study carried out during the months of April to July in 1974, on the fisheries in regard to its labor management. At here the word of adjacent seas fisheries in Korea denotes the fisheries carried out by fishing boats for one or two boats trawling, purse seinning, shrimp trawling, and whale catching. For the objective of this above study the auther randomly selected 257 crew-members for the questionaires and direct interviews and, with this method, proceeded surveys and investigations on the following factors such as the organization and its functions, personel administration in regard to placement and merit system, regulations and rules of working, wages and salaries, welfare facilities or considerations, safety and sanitation, human relations within organization and cooperation, and thus covered the whole important factors with the modern management system. The results of the studies are; The factors above the standard level are only on those of organization and functions, merit system and placement and human relations and for the rest the judgement are to be laid as below the standard level. And particularly revealing the problems on the following factors; 1) Wages and salary particulary on the payment upon laid out, and the payment of wages in advance. 2) Welfare facilities such as of the insurance and crew members' welfare for the good use of leisure time. 3) Placement and merit system in regard to ite method of appointing or empioying 4) Regulations and rules of working in regard to the vacation or leave of absence. 5) Safety problem particularly on the matter of sanitation or hygene. 6) Coopertion on the matter of participation on the interested problems on both parties. The above points indicated are, methinks, all derived out of the out dated method of management. Therefore, for the improvement of the labor management, first of all, nothing is more urgent than to adopt the modern labor management method as well as to encourage and enlighten the social responsibilities burdened on the enterprise.

We present microfluidic method to rapidly analyze the effect of temperature on the change of morphologies of Antarctic bacteria (Pseudoalteromonas sp., Shewanella vesiculosa, Shewanella sp., and Cellulophaga sp.). The microfluidic device is able to generate stable temperature gradient from 7 to$40^{\circ}C$ and dramatically reduce the number of experiments, experimental cost and labor, and amount of sample. Based on this approach, we found that specific bacteria transforming morphology into filament or elongated body strongly depends on cultivation temperature. Interestingly, we found that the morphologies of Pseudoalteromonas sp., Shewanella vesiculosa, Shewanella sp., and Cellulophaga sp. are elongated at below $25^{\circ}C$, above $20^{\circ}C$, above $15^{\circ}C$ and above $35^{\circ}C$, respectively. We envision the microfluidic device is a useful approach to analyze biological events with a high throughput manner.
