Urban renovation projects (reconstruction and redevelopment) have a longer licensing period than general housing projects, and many consultations with the licensing authorities require expertise. Most of the members of the union do not have basic knowledge of the maintenance business, so they have a lot of authority to promote smooth business Is entrusted to the union leader. However, contrary to the original purpose entrusted by the members, it is easy to find a case where the business is suspended because the union leader is exposed to corruption for the private interests of the union, and the members' disputes could not be resolved. In order to overcome this risk, the problem of the maintenance project was found through a questionnaire survey composed of practical experts, and a solution was presented through the KCSI evaluation model. This study mentioned the necessity of a responsible CM that can make independent business decisions without interference from the union, rather than a management-type CM limited to the cooperative's work assistance. In order to promote the construction industry's national role, it was necessary to revitalize responsible CM, so six practical alternatives were proposed.

The steady increase in livestock industry has greatly required the stable production of food and forage crops. As an alternative, rice-forage cropping system has been attempted in several southern areas. The present study was performed to understand whether an application of cattle-manure compost affects soil chemical properties and crop productivity in rice-forage cropping system, rice ${\rightarrow}$ summer oat ${\rightarrow}$ rye, in Jangheong county, south Jeolla province from 2013 to 2014. Treatments was composed of control (no compost), CM1 (compost application before rice transplanting), and CM2 (two-times compost application, before rice transplanting and after rice harvest), and inorganic fertilizers (N, P, and K) were equally dressed in all plots. Yields of rice were not significantly different between treatments, however, oat production was 1.25-fold higher in CM1 and CM2. Nutrient uptake amounts of rye were higher in CM2 than CM1 and control. Total nitrogen in soil was maintained stable level during crop cultivation. And soil organic matter contents in all treatments were increased by crop residue. Available P_2O_5$ and exchangeable K were increased by cattle manure application. Therefore, it suggested that the amount of nutrient by forage crop residue should be considered in rice-forage multiple cultivation.

The study is designed to develop a educational basic pants patterns for men, and has been analyzed focusing on the university textbooks published since 2000. We also used CAD programs and virtual fitting programs to analyze the fitness of pants. To do this purpose, after choosing 7 Men's Wear textbooks, selected patterns were drawn and measured using PAD system and were compared and analyzed. Also, the appearance evaluation was examined through virtual fitting and then evaluated 21 male and female university students in their 20s. After supplementing the problems of the patterns in the existing textbooks, a pattern was developed and verified the fitness of the developed pattern. The results of comparing the proposed measurement items of each textbook for the pants pattern indicated a significant differences in terms of hip circumference of each pattern, which were between 96~105cm. A comparison of the drafting methods of each pattern showed the drafting methods for the crotch length, the front crotch extension, the back crotch extension were the difference. The results of appearance evaluation were pattern E presented the slimmest fit and pattern D presented the loosest fit. As a result of analysis of pants pattern, a waist circumference 82cm, a hip circumference 98cm, a crotch length 24cm, a pants length 104cm and a ham line width 46cm were most suitable. The development pattern was evaluated as superior to the existing pattern through the appearance evaluation of the virtual fitting.

In order to maintain construction industry and to improve efficiency, the Korean government legislated private investment system. Private sector takes advantages by adopting CM (Construction Management) project system, however, public sector has relatively less capability and experience than private sector. In this paper, PSM (Partnership Support Management) is addressed in order to actively strengthen the project capabilities for public sector. PSM maintains existing CM project system because it is a concept of expended business model of CM. PSM needed to categorize the private participated project into 5 phases; project development phase, project announcement phase, project evaluation phase, project agreement phase and agreement changing phase. PSM business structure and business process considering stakeholder's interrelationship and participation are suggested in this research. Suggested PSM business model may not only increase a comprehensive understanding of government and project capability, but also may reduce work load and responsibilities for project momentum of private participation in infrastructure.

This study was designed to produce rounded belt pattern and tight-skirt pattern drafting method using 3D body scan data. Subjects were thirty women in their early twenties. In order to figure out the optimum cutting points, namely, where darts are made, using CAD program, curve ratio inflection points on the horizontal curve of waist, abdomen, and hip to find 1 point in the front, two points in the back part. The average length from center front point to maximum curve ratio was 7.7 cm(46.3%) on the waist curve; 7.9 cm(39.4%) on the abdomen curve. And the average length from center back point to maximum curve ratio point was 6.9 cm(39.0%) for first dart and 11.2 cm(63.3%) for second dart on the waist curve; 8.9 cm(35.8%) for first dart and 15.7 cm(63.3%) for second dart on the hip curve respectively. The cutting lines from were made up by connecting curve inflection points. After divided using cutting lines, each patch was flattened onto the plane and all the technical design factors related with patternmaking were measured, such as dart amount, lifting amount of side waist point, etc. Based on the results of correlation analysis among these factors, regression analysis was done to produce equations to estimate the variables necessary to draw up pattern draft method; F1=F8+1.1, $F4=2.5{\times}F2+0.9$, $F5=0.9{\times}F4+1.0$, $F6=0.3{\times}F4+0.4$, $B1=0.9{\times}B8+2.3$, $B4=2.1{\times}B2+1.3$, $B5=0.9{\times}B4+3.5$, and $B6=0.3{\times}B4+0.4$.

This study aims to suggest the patternmaking method of men's slim-fit four-panel jacket sloper in their 30's. The researcher collected four kinds of existing slopers and carried out appearance and movement evaluations twice. Then the researcher's sloper was developed by modifying and supplementing the existing sloper with high scores in the evaluations. The results are as follows: First, when comparing the existing slopers, ease on the chest varied from 13 cm to 17.8 cm. Actual measurements or formula method were used for the armhole depth, waist line, and hip line. It was one-third of armhole length for the sleeve cap height in most existing slopers. Second, the researcher's sloper had excellent scores in the appearance and movement evaluations (front neck depth, ease on the chest, front dropped length, ease on the sleeve cap, and the position that separate the two piece sleeves on the back). Third, the suggested sloper, has 13~14 cm for ease in the chest circumference and 2.5 cm for front dropped length. It sets to chest/4+2 cm for armhole depth, height/4+1 cm for waist line placement, and height/8 for hip length. The sleeve cap height is one-third of armhole length. These results will be useful when the industrial technical designers develop various jacket patterns.

In this paper, we propose and demonstrate an optimal design of wideband pulsed gamma-ray detectors. Pulsed gamma-ray detectors are designed to operate in a dose rate of $1{\times}10^6{\sim}1{\times}10^8rad(Si)/s$. The input parameter was derived based on the energy ratio of pulse gamma-ray spectrum and the time of the energy. The sensor output current was calculated based on the dose rate control circuit. Using the N-type Epi Wafer, the optimum condition detection sensor was designed based on TCAD. The simulation results show that the optimal Epi layer thickness is 45um when applied voltage 3.3V. The doping concentrations are as follows : N-type is an Arsenic as $1{\times}10^{19}/cm^3$, P-type is a Boron as $1{\times}10^{19}/cm^3$ and Epi layer is Phosphorus as $3.4{\times}10^{12}/cm^3$. Pulse gamma-ray detector diameter is the 1.3mm.

This study attempted to undertake comparative analysis of woman's jacket pattern and details based on the Crinoline and Bustle style of the 19th century, comprehend the relation and differences between the two styles. And it also presented the resultant characteristics and attempted reproducing the original dress of the past for the development of modern woman's jacket design. Larger portion was occupied for the breast front width than the back width for both Crinoline and Bustle style, which indicated the remarkable difference between these styles and modern jackets in terms of pattern size. Circumferences also showed that both styles had larger size for the front region than for the back. Divided by two types of pattern shape. The Crinoline style has a waist line and flare. On the other hand, the Bustle style does not have a waist line and has pleats. These two styles shows distinct differences of patterns even if they seem similar. It was essential to undertake the designing of models by giving a consideration to the characteristics of patterns of the two styles. With respect to how to sketch the study models which will be applied for the reproduction to modern body sizes were as follows: the front bust circumference; B/4 +1+1 cm, the back bust circumference; B/4 +1-1 cm, front waist circumference; W/4 +1+1 cm, back waist circumference; W/4 +1-1 cm, the height of sleeve crown; AH/3, armhole line; B/4, the back width /2; 17.5 cm, the breast front width /2; 16.5cm. And for the rest parts, sizes reflecting the characteristics of the patterns of two styles have been applied.

Tactel(Nylon66) union fabrics were woven with the specification of 70d/34f nylon as warp for sport wear jacket. Weft yarn has three types; 100% cotton yarn, nylon core-spun yarn and nylon-polyurethane covering yarn as weft. Fabric structers were plain, twill and satin weave structure with the air jet loom. The mechanical properties of 8 fabrics were measured with KES-F and primary Hand Values and Total Hand Values were calculated. The results of the study were as follows: 1) There was little difference among LTs of N/CM fabric groups. RT of the fabrics with CM100's was bigger than that of fabrics with CM80's, resulting that the fabrics with CM100's have better formability. In terms of weaving structure, twill fabrics have shape deformation. 2) In comparison of RTs with weft yarn type, RT of N-PU covering yarn was the highest, followed by Nylon core-spun yarn and cotton yarn. Thus, the fabric with N-PU covering yarn has better stability of shape deformation. 3) Stretch yarn could express an excellent silhouette formation and twill and satin structures were better structure to make curvature on human form. 4) 2HG/G value of nylon core-spun fabrics was larger than that of N/C fabrics, but the silhouette formation of N/C fabrics was excellent. 5) The RC of N/PU was the highest, followed by N/P, and N/CM. 6) Koski of N/PU fabrics was the highest, Numeri of N/PU and N/Co-I were relatively higher than the others. THVs of N/CM-IV and N/CO-II were lower than the others, resulting that, twill structure was better than plain structure for a sport wear uses.

For the purpose of standardizing sizing systems for infants and children's clothing, the researchers surveyed 20 different apparel manufacturers in Korea. The apparel production sizing systems used in the industry were analysed. The researchers also compared standard apparel sizing systems developed for infants and children's clothing in Korea. ISO, Japan, and U.S.A. The followings are the results of this study. 1. As survey findings of companies's views about sizing systems, boys or girls sizing system needed to be developed for 3 years old and over. The plus sizes are needed to be developed and children 9 years old and over need the plus size. 2. The body size specification in most sizing systems collected shows that chest circumference was increased 2cm for every infants sizes, and 3cm for boys and girls'sizes, from size 100 to size 130. However, the chest and waist circumference measurements were increased 4 to 8cm for large sizes, from size 130 to size 170. 3. There are similarity and dissimilarity among the standard sizing systems of ISO, Japan(JIS), U.S.A(ASTM), and Korea(KS). The ASTM developed infants'garment sizes for the babies who are 24months old and under. The most national standards, however, developed infant apparel sizing system for the babies under 105cm tall or 4 years old. 4. The range of body measurements covered by boys/girls sizing system were different by the nation. The U.S. system (ASTM) is for boys and girls who are taller than 120cm. The Japanese system(JIS) is for the children who are taller than 90cm.
