The purpose of this study was to characterize the somatotype of children and to provide fundamental data for the construction of the dress figure. The subjects for anthropometric measurements were 384 elementary school children aged from 6 to 7 living in Seoul and Pucheon. The data were analyzed statistically according to SPSS/PC ＋ version 3.1. Through the factor analysis, six factors were obtained. The six factors represented the body girth and weight, the height and sleeve length, the trunk length, the shoulder size, the body curvature, and the posture of upper torso, respectively. The subjects were classified into six clusters. Among the six clusters, four clusters covered about 95.9% of the whole subjects were determined as the sources of fundamental data for the children's dress figure.

The cone penetration test(CPT) has gained its popularity in site characterization indebted by its reliability, speed, economy, and automatic measurement system since its development in the 1930s. The CPT results, commonly consisting of cone tip resistance, sleeve friction, and pore water pressure measurements, allow us to classify soils as well as to reveal their engineering characteristics. The site condition at which the CPT is allowable is often dependent on the capacity of a CPT system. In Korea, it has been considered that the CPT could be appled only to soft soils in most cases because CPT systems available for stiff soils are very rare due to their expensive procurement and maintenance cost. Luoisiana Transportation Research Center(LTRC) has developed and implemented a field-rugged continuous intrusion miniature cone penetration test(CIMCPT) system since the late 1990s. The miniature cone penetrometer has a sectional cone area of $2cm^2$ allowing system capacity reduction compared to the standard $10cm^2$ cone penetrometer. The continuous intrusion mechanism allows fast and economic site investigation. Samsung Engineering & Construction has recently developed and implemented a similar CIMCPT system based on its original version developed in LTRC. The performance of the Samsung CIMCPT system has been investigated by calibration with the standard CPT system at a well-characterized test site in Pusan, Korea. In addition, scale effect between the miniature cone penetrometer and the standard cone penetrometer has been investigated by comparing the field test results using the both systems.

According to the design method for constructing the G gori(the traditional Korean jacket)collar, there are differences in form after its completion. In the construction design of the midsection of the gusset as in that of the basic G gori, not only was the positioning of the two sides of the collar not smooth, but also, when the collar strip was attached, there would be an imbalance on one side or the other so that it was difficult to achieve symetry. Therefore in this project, by applying the pattern design of the gusset midsection to that of the collar midsection, not only did attaching the collar and the collar strip create a visual effect by equalizing the lengths of the tow sides, but the construction was also easy. This method of construction introduces the three-dimensional aspect of the human form in its conic, spherical and cylindrical aspects, so that, through schematizing the scientific character of Korea's clothing, its appropriateness is verified. As a matter of fact, since th-ere in no standardization of pattern whether for educational use or for mass-produced clothing, so that even the patterns used in computer-assisted design are executed according to the designer's personal skill, the reality is that after completion of construction the quality has not been uniform. For this schematization, inverse calculation of measurements pertaining to the calculation formula and of teaching materials has been referenced. In particular, the partial requlation of the calculation formula pertaining to the basic pattern construction, the method of making the collar midsection, and the construction method of the extreme and mean ratio adjustment can be adjusted for all measurements, thereby providing the establishment of a design criterion and the possibility of the standardization of construction methods. The production method for the pattern design is as follows: 1) The conic angle for the G gori's girth, length and neck width is fixed at 70 degrees. 2) The radius of the cone is B/2. 3) The calculation formula is B/4 + 1.5cm 4) The armhole formula is B/4, the same as in the basic method. 5) The width formula is B/10. 6) The ratio of the collar junction(width of collar + width of collar strip)to the gusset length is 5:8. 7) The length of the side seam is a length intersecting the armhole line and the conic radius (B/2), that is an arc that exceeds the length of the G gori's midsection; the component ratio of this length to the collar junction is accordingly 13:5. 8) The curve frame length of the back midsection is an arc exceeding B/4(the armhole line). 9) The ratio of the sleeve opening calculation formula to the armhole length is 8:5, forming an arc with the midsection length.

This study was initiated to develop a uniform design suitable for child inpatients. The experimental hospital inpatient uniform design was developed based on the results of the prior studies. The panel was composed of 5 experienced nurses and 5 clothing specialists. They evaluated the function of the experimental inpatient uniforms developed in this study. The experimental hospital gown design was reformed based on the panel's evaluation.1'hen the child inpatients performed the wear test for the reformed experimental hospital gown. The results of the study are as follows; 1. The child inpatient hospital gown design of the most hospitals were similar to the adult patient's uniform : the V-neckline shirts with full length set-in sleeves. The bottom was full length pull-on pants. The fabric was white cotton with blue hospital logo and stripe print in most cases. 2. The panel's specialty affected the evaluation of the uniform design. The nurses concerned about the durability after washing and ease for medical treatment. The clothing specialists cared about the features related to the clothing construction and ease for physical movement of body. 3. The most preferred hospital inpatient uniform design by the panels was the shirts or one- piece gown with three-quarter length sleeve and overarm seam opening. 4. The researchers developed one-piece dress gown for the children under two years old. Three different size pajamas were developed for children 2∼5 years old,5∼8 years and 8∼12 years old.

Jeogori, Korean jacket, can be categorized into two styles. Traditional style Jeogori is based on conventional construction method for ceremonial or festive occasions. Contemporary casual style Jeogori is based on western style flat pattern making for better fitting and functionality. Traditional style Jeogori is quite flat on human body because it is not considered the grade of shoulder line and is drawn by vertical & horizontal line. This characteristic feature causes weakness in functionality and comfort compared to contemporary casual style. Apparently contemporary casual style has better wearing comfort. Yet to most Koreans, contemporary style Jeogori seems to lack of some characteristic style of its own. This study is to find out how to make Jeogori well balanced in terms of functionality, fit, comfort and traditional style. Currently used Jeogori patterns are compared in order to select the best among them. Onto the selected pattern, several alterations were tried focused on shoulder, armhole and sleeve lines to make optimal modifications. After several comparative fitting tests, the final pattern making method was suggested.

This study utilized the wearing test of subjects and a preference survey to determine wearing preference on types of blouses according to shoulder angle. The shoulder angles of the subjects were set as average shoulder, slopping shoulder, and square shoulder. The blouse sleeves were set as set-in, raglan, and kimono according to five domestic clothing construction books. A total of 15 blouses were made and tested by different bodices and sleeve types. The wearing test of subjects had the human subjects evaluate the appearance of the subject looking at the mirror while standing as well as evaluated the sensation test while not looking at the mirror. The preference survey was given to 100 females and was conducted using photos with combinations of three types of sleeves and shoulder angles in a survey under the same conditions. The average shoulder showed that set-in with the highest score in the wearing test was also preferred in the preference survey. The slopping shoulder evaluated the highest score in the wearing test by mirror; however, the preference survey showed that raglan was the most preferred choice. The squared shoulder showed that raglan with a high score in the wearing test by mirror was also preferred in the preference survey.

Concrete wedge anchor is one of structural components to transfer load of an object attached to a primary structure. Recently, as retrofitting concrete structure is becoming a main issue, mechanical capacity of the anchor should be secured enough. In spite of the structural safety of Cast-in-place anchor, Post-installed anchor is more widely used with ease of placement or change of construction method. However, the post-installed anchors domestically produced have excessive coefficient of variation over 15% of ultimate tensile strength, which yields deteriorated quality in tensile strength. In this research, tensile strength test of anchors, which have improved sleeve and header and produced by a domestic company, was conducted for two variables, concrete strength and effective embedment depth. As a result, enough coefficients of variations were secured in all specimens. Also, in comparison to foreign products, the domestic ones have equal or higher performance.

The purpose of this study is to compare Jegory with Simii, and to understand the construction of Jegory, assuming that Jegory is related to Simii system. The results obtained are as follows ; 1. Teie-ku-li was the first record among the name of Jegory in literature, was called about A.D. 1408. 2, When Jegory and Simii were cut, front-back width and sleeve length standarded on the width of cloth. 3. The cutting of Jegory disposed to seperate right and left width, to connect front and back width up to the middle term of Chosen Dynasty Period. 4. The sewing order of the Simii was Dungsol-Jindong-Baerae-Sougu. The sewing order of the Jegory in $\ulcorner$ The Book of Chosen sewing$\lrcorner$ was Shoulder-Jindong-Baerae-Sup-Dungsol-Kit and in literature of 1960's it was similar to Simii. 5. The lined clothes in $\ulcorner$The Book of Chosen Sewing$\lrcorner$ was sewn to put the inside in the surface, different from the literature of 1960's. 6. In Chosen Dynasty Period the shape of Simii depended on $\ulcorner$Moon Kong Ka Rye$\lrcorner$, but it was changed to similar to Jegory in the latter term. 7. The empty void in Jegory offers usefulness. It relates to Oriental negativism that yin is more useful than yang.
