Unlike other ready-made suits, which are normalized based on aspects like, designs, materials, sewing methods, has to be worn for three years, designing and pattern development of school uniform depends greatly on satisfaction and appearance. Furthermore, school uniform is of importance as many teenagers spend most of their time at school. In the present work, an attempt has been made to suggest ideal school uniform for female middle school students based on their actual uniform conditions and design preferences, so that the demands of artistic aspect, and the requirements of a suitable uniform for a female teenager can be fulfilled. Initially, a survey about the actual wearing condition was held to figure out the actual uniform conditions and design preferences. Based on the result of the survey, two types of school uniform were made with different patterns. Finally, the most ideal school uniform for female middle school students was suggested based on the experiment involving a few aspects such as suitability and functionality. It is conjectured that school uniform survey and investigation, could provide useful information to the school uniform business market.

The grouting is one of the improved techniques which is aim to decrease the permeability and to strengthen the soft ground. But The grouting method has many problems about a suitability of grouting procedure and an effectiveness of grouting after grouting work because of a technical characteristic operated inside the soil. The grouting $p{\sim}q{\sim}t$ chart of a typical index about grouting rate and time alteration of grouting pressure is one method to estimate the suitability of grouting factor with monitoring during grouting procedure. This study is automatic grouting system (AGS) which can control the testing and grouting procedures. It can make the detailed $p{\sim}q{\sim}t$ chart and analyze the grouting characters of the ground by comparing the detailed pattern of $p{\sim}q{\sim}t$ chart with standard pattern. If using the $p{\sim}q{\sim}t$ chart derived from AGS in the grouting work, it is an objective standard estimating the suitability of grouting factor with grouting materials, grouting method, grouting rate and grouting pressure, as results it expects successfully to improve reliability of the grouting work.

This study developed an ideal jeggings pattern with an improved body fit for 20-24 year old females. The results of the study are as follows. First, samples for wearing test were made using jegging patterns from three manufacturers; subsequently, one pattern with a relatively outstanding body fit was selected from the first test. The selected pattern suggested a tight knee, belly, and crotch, high front waist line, and low back waist line. The side lines were also lean to the front; consequently, the front hip width was extended for 0.5cm for more space around the belly and the extended front knee part for 0.2cm to increase moving suitability to fix the leaning side lines. A 1cm front waist line was extended for 0.5cm to fix it lower; in addition, the back waist line 3.0cm was extended for 0.5cm to heighten it. The crotch width was also extended for 0.5cm to add more space. The second wearing test for the fixed forms were evaluated for their outstanding features in appearance as well as moving functions that were proposed as final jeggings forms. The results of the study suggested a jeggings pattern with a better body fit using manufacturer patterns that can be used as basic data for pant patterns with better fitting using various stretch fabrics.

The purpose of this study is to propose a standard of converting 3D shape of men in twenties to 2D patterns. This can be a basis for scientific and automatic pattern making for high quality custom clothes. Firstly, representative 3D body shape of men was modeled. Then the 3D model was divided into 3 shells, front, side and back. Among them, the front shell was divided into 4 blocks by bust line and princess line. Secondly, curves are generated on each block according to matrix combination by grid method. Then triangles were developed into 2D pieces by reflecting the 3D curve length. The grid was arranged to maintain outer curve length. Next, the area of developed pieces and block were calculated and difference ratio between the block area and the developed pieces' area is calculated. Also, area difference ratio by the number of triangles is calculated. The difference ratio was represented as graphs and optimal section is selected by the shape of graphs. The optimal matrix was set considering connection with other blocks. Curves of torso upper front shell were regenerated by the optimal matrix and developed into pieces. We validated it's suitability by comparing difference ratio between the block area and the developed pieces' area of optimal section. The results showed that there was no significant difference between block area and the pieces' area developed by optimal matrix. The optimal matrix for 2D developing could be characterized as two types according to block's shape characteristics, one is affected by triangle number, the other is affected by number of raws more than columns. Through this study, both the 2D pattern developing from 3D body shape and 3D modeling from 2D pattern is possible, so it's standardization also possible.

The study is to develop and present a leggings pattern that is suitable for the human body by using a standard body type avatar for a female in her 30s. As a research method, the average body type was selected from adult women in their 30s, and the appearance was evaluated using the CLO software program. The data analysis of this study compared the dimensions and shape of each part by legging. The leggings pattern suggested based on the above research results was determine to be a total length of 80.6cm and hip length of 24cm, and the knee length was set by dividing the legging in half from the waist to the hem and then adding 5cm. These figures were evaluated higher than Company D in terms of the adequacy of the upper part of the front and rear plates of Company A as well as the adequacy of the knee lines. Company A's figures were applied and corrected. For the front plate, the waist circumference was divided by 4, and 3.5cm was removed, and the hip circumference was set by dividing the hip circumference by 4, and 3.8cm was removed. In the appearance evaluation results Company D was highly evaluated in the suitability evaluation of the waist and hips, and the waist and hips were set using the pattern of Company D. The length of the front panel was modified by dividing the hip circumference by 4 and adding 1.8cm to the length, and the length of the back panel was modified by dividing the hip circumference by 3 and adding 8cm after dividing the hip circumference by 0.8cm.

In this paper, we applied the shape parameters of the exponentialized exponential life distribution widely used in the field of software reliability, and compared the reliability properties of the software using the non-homogeneous Poisson process in finite failure. In addition, the average value function is also a non-decreasing form. In the case of the larger the shape parameter, the smaller the estimated error in predicting the predicted value in comparison with the true value, so it can be regarded as an efficient model in terms of relative accuracy. Also, in the larger the shape parameter, the larger the estimated value of the coefficient of determination, which can be regarded as an efficient model in terms of suitability. So. the larger the shape parameter model can be regarded as an efficient model in terms of goodness-of-fit. In the form of the reliability function, it gradually appears as a non-increasing pattern and the higher the shape parameter, the lower it is as the mission time elapses. Through this study, software operators can use the pattern of mean square error, mean value, and hazard function as a basic guideline for exploring software failures.

Many processing times for fabricating complex shaped parts by near net shape process such as thixoforming or semi-solid forming, are required due to the time for die design, induction heating and forming process. Therefore, for the thixoforming process, multi-capacity induction heating process is very important due to the reduction of the processing time and cost. It is indispensable to adopt a power-time heating pattern which manages to conciliate complete eutectic melting at the core with limited overheating at the periphery. The total reheating time is thus dependent on billet diameter; in inches$(pm20%)$. Typically, high frequency is used for the rapid reheating of the billet to the eutectic temperature range and low frequency for the remelting of the desired fraction of liquid and for the radial homogeneization of the liquid fraction. So in this study, the multi-capacity induction heating conditions of ALTHIX 86s alloy to reduce the processing time and cost would be proposed. The suitability of multi-capacity induction heating conditions would be verified through the comparison to Garat's data.

In this paper, we proposed the dimensional system and pattern of middle-aged women's rashguard swimwear for breast cancer patients. First, a survey of 37 breast cancer patients was conducted to determine the preferred swimsuit design for breast cancer patients. According to a survey of breast cancer patients, a rashguard swimwear with a low-exposure chest was designed. It has a pocket shape in which the cap is easy to insert and the cap is fixed. Second, we developed a dimensional system for swimsuits for breast cancer patients. Using direct measurement data from Size Korea for 1,625 women aged 30 to 69, 17-sizes for breast cancer patient's swimsuits were set through cross-analysis of major dimensions, with a coverage rate of 74.3%. It also extracted a standard size of bust circ. 90cm, hip circ. 95cm, and trunk circ. 150cm. Third, we developed a pattern for the central size of the swimsuit for breast cancer patients. For this purpose, we first produced the first central size pattern, and then completed the pattern after modifying it through the second and third wearing experiments. Experimental suits were produced at each pattern-making stage to evaluate wearing fit and motion suitability. Finally, the reduction rate of each dimension item for optimal pattern production was obtained, and the lashguard swimwear pattern for breast cancer patients was developed.
