Industrialization and urbanization occurred-traffic delay, traffic accident and parking problem etc.-variety of transportation problems. Parking problem is one of the transportation problem then transportation engineers would get involved in trying to solve parking problem. A way to overcome a variety of parking problems needs preliminary data for conditions of parking but it lacks the preliminary data to do so. Thus this study analyzed a characteristic of a parking through a field survey for parking in Daegu Metropolitan City. This study analyzed parking characteristic of parking operation method. This study result reveals difference between a toll parking and a no charge parking characteristic. Thus a close examination for a toll parking characteristic and a no charge parking characteristic is a prerequisite for a rational parking policy.

The objective of this study is to propose the basic design plan of system by comparing and analyzing application environment of lift and elevator group control system, as preliminary study for the application of group control system to lifts for high-rise construction. The basic design plan is suggested in terms of group control algorithm, hall call system type, operation information recording device, information communication method, and operation method. The results of this study can be used as basic data for software and hardware design for application of group control technology of lifts for super tall building construction and ultimately contribute to improve the operation efficiency of lift for high-rise construction.

In free-formed formwork, there is a problem that the productivity of the construction is deteriorated due to the expensive form, the long manufacturing period, and the high degree of construction difficulty. In order to solve these limitations, there is a need to research improvement from the phase of manufacturing free-formed form. Therefore, this study is to derive significant technical characteristics using QFD approach as a preliminary study to develop manufacturing system of the free-formed form for improving the productivity of free-formed construction formwork. This study employs the QFD to reflect users' needs into technical characteristics, and analyze correlation between users' requirements and the technical characteristics, then weights them by their importance.

Rapid urbanization occurred a variety of transportation problems. Parking problem is one of the most problems of transportation problem then transportation engineers would get involved in trying to solve parking problem. A way to overcome a variety of parking problems needs preliminary data for conditions of parking but it lacks the preliminary data to do so. Thus this study analyzed a characteristic of a parking through a field survey for parking in Daegu Metropolitan City and Ulsan Metropolitan City. This study analyzed parking turnover, parking use ratio and parking basic unit for characteristic of a parking of each use districts and each cities. This study result reveals difference between the use districts' parking characteristic and cities' parking characteristic. Thus a close examination for use districts' parking characteristic and cities' parking characteristic is a prerequisite for a rational parking policy.

This paper reports a preliminary result of an acoustic study on the stress and intonational system in Lakhota, a native American language. It investigates how the stress and intonation in Lakhota are phonetically manifested; and how the stress interacts with other prosodic factors. The results preliminarily obtained from one native Lakhota speaker suggest that the primary cue of the stress is relatively high F0 which is often accompanied by higher intensity (for the vowel) and longer VOT (for aspirated stops). The results also indicate that stress is not reliably marked by duration. The stress system, however, interacts with the intonational pattern, such that, for example, intonational peak falls on the stressed syllable with a general pattern of L+H* and that it interacts with the boundary tone L%, resulting in mid tone utterance-finally. This paper can be viewed largely as a qualitative study on an understudied native American language, Lakhota and as forming a basis for further development of its stress and intonation system whose acoustic properties of its prosodic system have not been investigated before.

Purpose: The purpose of this study was to identify the effect of tourmaline Gemstone therapy on dysmenorrhea and painful menstruation in middle school female students. Method: This study employed a one-group pretest-posttest design. Data was collected from 15 subjects from September 1 to November 31, 2005. Tourmaline Gemstone therapy was provided once during a peak time of dysmenorrhea and painful menstruation. The instrument used were modified Moos's MDQ(Menstrual Distress Questionnaire) tool and VAS. Data was analyzed with the use SPSS. Result: There was a statistically significant difference in the dysmenorrhea(t=5.50, p=.000) and painful menstruation(t=6.49, p=.000) after the intervention with tourmaline gemstone therapy. Conclusion: Tourmaline Gemstone therapy using a Tourmaline Gemstone therapy has a positive effect on decreasing dysmenorrhea and painful menstruation.

The existing defect management is focused on step before closing work, a builder preliminary research and tenant preliminary research. Each step is not related. And the existing study on defect management mainly classify into work type and defect type according to work type. This study divide into defect part. Also this study propose PDA based web and 3DCAD for improving method of existing defect management.

The visualization of information serves as a valuable tool for facilitating communication and exchange of opinions among stakeholders by conveying information in an intuitive and clear manner. As a preliminary study of visualization for construction field, this study proposed a model for generating three-dimensional floor layout using 360-degree panoramic cameras. The model integrates the layouts by calculating normal vectors of the plane which has openings, and applying translation and rotation matrices between the normal vectors. The results of this study can contribute to improving communication in construction sites by incorporating visualization, and further to the digital transformation of the construction industry.
