Since early 2000s, the use of construction management(CM) in the public and private building sectors has rapidly grown in Korea. In addition, the use of CM services during pre-construction stages has been increasingly recognized as a critical factor to succeed in construction projects. Understanding clients' needs of pre-construction CM services is important for CM firms to strategically prepare and cope with market needs. The objective of the paper is to investigate and compare the usage level of CM services in public and private building projects during pre-construction stages, and to identify key characteristics and implications for CM firms. The paper identified that although there are some differences in CM service needs between public and private sectors, time management and cost management commonly showed the higher usage level.

Since the Construction Management(CM) was introduced into the Korea construction industry, the efforts for acceleration of CM adaption have been continued. The fact that an owner organization has the essential key to successful application of CM delivery method is true, but there has been no study on owner's organization. An owner should decide their organization type and measure their current needs of each CM business functions for successful application of CM. After the needs of CM business functions are measured, the owner should reinforce their required business functions through strengthening their in-house capability or outsourcing. Thus, this paper defines four kinds of owner organization type and suggest the form for evaluation of owner's CM ability and analyze about needs of each type's CM ability through making up question.

Since the Construction Management(CM) was introduced into the Korea construction industry, the efforts for acceleration of CM adaption have been continued. The fact that an owner organization has the essential key to successful application of CM delivery method is true, but there has been no study on owner's organization. An owner should decide their organization type and measure their current needs for several different construction business functions for successful application of CM. After the needs of CM business functions are measured, the owner should reinforce their required business functions through strengthening their in-house capability or outsourcing. Thus, this paper defines four kinds of owner organization type and suggest the form for evaluation of owner's CM ability and analyze about needs of each type's CM capability through a survey.

In Domestic, the beginning of CM system was at December 1996 by 'Construction Industry fundamental law'. Today the needs of CM is more and more during 10 years. Although the time of CM's induction and high-quality human resources are insufficiency, various studies and developments's level through theoritical base and academic level is good which are compared by developed countries's. But still now the effort of CM product measure part, especially public sector is not enough. Besides, the existing check-list is for project owner so it needs to make up for balanced view as organized 4way-view of owner, CMr, designer, constructor. On this study, produce the list of check-list and then weight of each list by view of owner, CMr, designer, constructor. The completec check-list will be useful for CM product measure objectively .

Since construction management(CM) was recognized as a formal procurement route by law in 1995, it is interesting to observe the trend of its increasing adoption. Particularly in the public sector, local government clients more adopted the CM Procurement route than central government clients. The objective of this paper is to investigate and analyse the motivation of local government clients in selecting the CM procurement route. It is important to understand such motivation for achieving a better understanding of public client's CM needs and for promoting CM business in the public sector.

This study was conducted to investigate the performance times, CM position and CM speed, pole chord length and pole chord angle, whole body angular momentum(X axis), and grip width in pole vault event according to the event and phase; touch down, pole plant, take-off, maximum pole bending pole straight, pole release, peak height, and foot contact, pole contact, free flight. The pole vaulting of four male elite vaulters including six trial were filmed using two video digital cameras at 60 Hz at 56th national athletic match, and data were collected through the DLT method of three dimensional cinematography. In general the better jumper is, the longer the performance time is. And the greater CM speed is, and the better his transformation ability of CM horizontal speed into vertical speed is. As he uses a longer pole, his grip is higher, and it is a enough for him to rock back his body, so that he pulls and pushes the pole well keeping his hips close to. An greater maximum angular momentum and early positioning of the hips parallel to the bar makes his body far side of the bar and his bar clearance easier. Specially our national jumper needs to have more powerful braking force during foot contact phase, and take his body on the pole after maximum pole bending, and pull and push the pole strongly keeping his hips close to. Also he needs to have stronger muscular strength in order to control the longer pole and use the pole of proper tension more efficiently.

This study developed a functional dress shirt for adult males that reflected the body surface variation of a human body section by motion. This study conducted a 3D body scan for 8 subjects in their 40's based on the Size Korea 2010 database. Data recorded the proper posture change value and body surface change value to develop functional dress shirts for adult males. We scanned the subjects with a 3D body scanner for five primarily male wearing dress shirts and operating postures, right standing, arms raised to $90^{\circ}$ horizontal forward position, arms raised $90^{\circ}$ to the horizontal position side, lift up the arm $180^{\circ}$, and arm forward $90^{\circ}$ in a bent posture. We analyzed the 3D scan data from those motions to examine change of length using 3D software Rapidform XOS. The results indicated that the body surface sections with contraction were the front and rear shoulder area, armpit and central length as well the width of arms at more than 10%. The increased body section included the body and armpit back length; in addition, the rear arm vibration girth and under arm girth were more than 10%. In order to reflect the size variation of for each motion, the ease amount of the front and rear shoulder length and width needs to be reduced 20% because it affects the shoulder length during the right standing. The results suggest that the ease amount of the shoulder length should be minimal. The ease amount of the back size needs to be 0.5-2cm bigger and set 0.5-1.5cm longer than the dress shirt length side drooping to compensate for the side length shortage of each motion. The sleeve length needs to be 0-0.5cm shorter, and ease amount of the girth of sleeve bottom needs to be reduced 0-0.7cm due to the size variation of arms. However, the girth of the rear arms is suggested to be 0-0.6cm longer in the ease amount to the rear arm girth as the extension is more than 10% over the width and length of each motion.
