The objective of the study is was investigate the condition of the battle dress uniform worn by male members of the Korean Police Special Weapons Attack Team(KP-SWAT), identify problems, and provide basic raw materials for developing improved design of BDU. For this purpose, the researcher conducted a questionnaire survey on 92 male members of SWAT (Special Weapon Attack Team) units in Seoul using a questionnaire developed through observation and interview. Also, the body sizes of male SWAT members were measured. According to the results of body size measurements, male SWAT members generally require uniforms with a target bust girth, armhole, biceps circumference, thigh and calf circumference, longer jacket length, sleeve length, and trouser length to the knee. According to the results of the questionnaire survey, they reported dissatisfaction with the fit. In addition, they said that the Pockets are positioned too low for convenient use. Many subjects reported that their trousers were too short because of the rubber rings at the bottom of the legs. In addition, many subjects requested the alteration of the inconveniences caused by the designs finished with velcro on the bottom collar of the upper uniform, the marks and ensigns of the upper uniform, the bottom of the upper and lower uniform, and several pockets. Furthermore, there were many complaints concerning how they had to wear their uniform. The most frequently worn out and the body parts most often injured in field training and operations, they were reported, on the upper uniform, as the elbow, collar, neck, armpit, shoulder, and sleeve hem in that order, and on the lower uniform, the knee, interior calf, waist (belt rings), buttocks (rear pockets), and the bottom of the trousers (ankle) in that order As for questions concerning priorities in the improvements of the operational uniform and preferred design, the subjects recommended improvement in safety (protectiveness), workability (motional flexibility), design (shape), fit (size), comfort, ease in terms of putting on and taking off, etc., and the majority preferred two-piece designs ($67.4\%$), followed by one-piece ($30.4\%$), or both ($2.2\%$).

This study mainly analyzes that designing patterns of an adult women Jeogori that takes advantage of patterns from each textbooks and complements the disadvantages based on the analysis of data from the dress evaluation and comparison of materials. The modification of a size specification is needed for the standard body as an adjust of the length of Jogori between front and back, mediation for bust width between front and back, a movement for the based line of Sup and Godae. As a result, the suitable pattern according to the standard somatotype is as below. Jeogori Length of front is determined by the length of back which was measured from side neck point to bust point plus three centimeters, and give three and half centimeters more in front. This three and half centimeters is for the curved in front of your body due to the chest. Bust width of front and back have to show the differences of human body. Bust width of front is calculated as bust girth into quarters and add two centimeters. Bust width of back gives one centimeter behind the curve from the center line in order to reduce the floating phenomenon. So, the amount of center back line dart is one centimeter. Arm hole girth measures as dividing bust girth into four. Also, Goedae width has two methods to measure. First, divide bust girth into ten equal parts and subtract 0.5 centimeters from it. Second, measure neck girth and divide it by four. Sleeve length is equal to Hwajang minus bust width of front. Hand wrist calculates in using bust girth. Make bust girth into quarters and multiply three fifths. Side line measures as deducting from Jeogori length of back to Arm hole girth and multiply two thirds.

The concept of a non-contact type of UV disinfection system was introduced in this study. UV lamps and their quartz sleeves hang over the water surface and there is no interface between the sleeve and water. Obviously, there is no fouling. Based on optical laws and other UV distribution models, a detail mathematical model for a non-contact type UV disinfection system was developed in this study. Pathway length of UV light in a non-contact type photoreactor is longer than that in a submerged type photoreactor because the light is more refractive while passing through 3 interfaces of medium. But the pathway length passing through the water media is not significantly longer than that in a submerged type photoreactor so, the absorption of UV light by water is not significantly different from the other system. Due to the reflection effect, UV intensity is rapidly decreased as the horizontal distance from the light source is increased. The reflective attenuation in a non-contact type photoreactor is higher than that in a submerged type photoreactor. These mean that the short photoreactor is advantageous than the narrow-long photoreactor for the non-contact type photoreactor in an optical point of view.

This paper deals with shrink fit analysis of rotor by 2D cross-section, 2D axis-symmetry, and 3D FEM model. And this paper presents 2nd order approximation function of thermal expansion displacement by design variables (shape dimension, heating temperature, sleeve length, interference etc.), table of orthogonal array and RSM(response surface methodology). The possibility of the rotor with shrink fit is evaluated by thermal expansion displacement. If thermal expansion displacement is larger than interference, shrink fit enable to make the rotor. 2D axis-symmetry model and 3D model are more reasonable than 2D cross-section model, because stress and strain is different along length of shaft.

This study examined the wearing conditions of compression wear for weight training. Compression wear has recently received significant attention from the public and athletes as high-level functional sportswear. The survey was conducted on 373 men in their 20s for general information on purchase behavior, preferred brand, function, and preferred design. The majority of participants (n=181) were aware of the function of compression wear. The most selected reason for wearing compression wear was for its convenience during sports activities. Respondents had the greatest preference for designs with a round neckline, regular leggings type, upper arm-length sleeve, and thigh-length bottom. Respondents also wanted a stronger compression in the core muscle part (abdomen, back, and waist).

A number of factors combine to make ultraviolet radiation a superior means of water purification for ground water, rainwater harvesting systems and so on. Ultraviolet radiation is capable of destroying all types of bacteria. Additionally, ultraviolet radiation disinfects rapidly without the use of heat or chemical additives which may undesirably alter the composition of water. In a typical operation, water enters the inlet of a UV lamp and flows through the annular space between the quartz sleeve and the outside chamber wall. The irradiated water leaves through the outlet nozzle. Several design features are combined to determine the dosage delivered. The first is Wavelength output of the lamp, the Second is Length of the lamp - when the lamp is mounted parallel to the direction of water flow, the exposure time is proportional to the length of the lamp, the third is Design water flow rate - exposure time is inversely related to the linear flow rate, the forth is Diameter of the purification chamber - since the water itself absorbs UV energy, the delivered dosage diminishes logarithmically with the distance from the lamp. In this paper, It describe the how to design optimal UV disinfection device for ground water and rainwater. To search the optimal design method, it was performed computer simulation with 3D-CFD discrete ordinates model and manufactured prototype. Using proposed design method manufactured prototype applied to disinfection test and proved satisfied performance.

This study was performed to devise a sizing system for child hospital gown(uniform). The researchers surveyed the usage of child hospital gown and developed a sizing system for the child hospital gown. The suitability of revised size specification of gown was evaluated. 219 child inpatients participated in the survey and 13 child inpatients took part in the wear test. The results of the study were as following. 1) 71.7% of the subjects wore the uniform shirts. however numerous number of subjects did not wear uniform pants that the hospital provided(52.5%). The 68.2% of children who were shorter than 100cm did not wear uniform pants. 2) The most significant reason not wearing the hospital gown was unsuitable sizing system (42.1%). Inconvenience for donning and doffing comes next(26.2%). 3) The least satisfied garment size problems were the pants length and sleeve length. 4) The researchers developed a sizing system for the child hospital gown. The system provides 4 different sizes for children age from 2 months to 12 years. One-piece dress style was suggested for the smallest size(XS). The larger sizes(S. M. L) were designed in pajama style. 5) The sizing system developed in this study was moderately satisfied by the users.

For the purpose of providing basic data for the development of size specifications for middle-aged women in Busan, one dimensional measurements were made with the subjects. ranging 45 to 59 in age. The following are the conclusions : 1) According to ages, the middle and elder groups of the middle-aged women shared similar body types, having shorter height, more lowered bust. and increased upper-body depth and girth factors, compared with the earlier middle-aged women group. But the thigh girth of the elder middle-aged group (age: 55∼59) was the lowest, maybe owing to the aged lower-body muscles. 2) In the comparison with national averages. armhole girth, elbow girth, wrist girth. back waist length, side neck point-B.P.-waist line, and sleeve length showed great differences. This is problematic in that the national size standards fail to reflect each legion\`s peculiar body type characteristics. 3) Even though body types were classified according to drop value criteria suggested by KS specifications, 23.05% did not belong to the criteria. They were thus classified as A, N, and H body types, following the distribution of the present experiment. 4) In consideration of the economy factor of the production and sales of the clothes industry, the combinations of height and chest garth for the middle-aged Busan women were as follows: 155cm-85cm (Body Type A) 150cm-88cm (Body Type N), and 155cm-94cm (Body Type H).

This study investigated the casual jacket design preferences of women aged 50s and 60s and suggested a prototype design for functional clothing. All age groups liked the casual jacket with a length between the waist and hip, a convertible collar, and a single-breasted design. Those in their 50s preferred fitted or semi-fitted casual jackets while those in their 60s preferred semi-fitted casual jackets. Although, there were significant differences between the preferred jacket designs and ready-made brand jacket designs, most brand jacket designs were casual, semi-fitted, middle-hip length, single-breasted, and with stand-rolled or convertible collars. The analysis of the sleeve styles in brand jackets showed that consumers needed designs that are more decorative. Fashion designers for senior citizens need to design elderly clothing that is comfortable, fashionable, functional, and considers a universal design for ease of clothing function. It will also make the senior citizen fashion market more appealing to consumers. To provide jacket designs for senior citizens, we suggested casual jacket designs for embedding a functional device as well as a new jacket design library for women in their 50s and 60s.
