The particulate matter that was emitted always come up by atmospheric environmental problem. Running on the road vehicles must have regular inspection at regular period and make sure the emissions of exhaust gases exceed the legal standards. Emission test for the atmospheric environment, but it is not free from the particulate matter. Currently, emission test of vehicle inspection is divided into regular inspection and close inspection. Regular inspection and close inspection differ not only the method of emission test, but also the facility standards that must have for this inspection. According to the "Regulations on the Implementation of Comprehensive vehicle Inspection, etc.", close inspection must have trapping device that is trap particulate matter by emission test to vehicle. However, regular inspection is different. Regular inspection do not specify any criteria for trapping facilities. Therefore, this study is confirm how to prevent the emission of particulate matter to the atmosphere during the year when mandatory trapping facilities are required to trapped particulate matter in the regular inspection.

This study was empirically intended to determine obstacle factors of the global start-up promotion for the international inroad of global start-up companies. The statistical analysis of reliability and validity was conducted through the AMOS structural equation model after surveying 300 companies over 5 years old into start-up in metropolitan cities across the country. The findings are as follows. The global start-up growth had a very close relationship with capital, product development period, quality and human resources. And capital as a start-up obstacle factor was insignificant, but development period, quality and human resources had a close relationship with industrial competitiveness. Even in the mediating effect of start-up obstacle factors on industrial competitiveness, capital was rejected, while quality, development period and human resources were adopted, having a positive mediating effect. These results demonstrate that capital is not a big obstacle to the management because of the continuous support of the government due to the nature of start-up companies, but growth is in a remote future as long as there is no independent product competitiveness to maintain the quality of products at a certain level and support of professional workforce to develop and commercialize them.

VRML is a implementation language which can express the characteristic of the object as it is. There is not many research to concern how it must combine close range Photogrametry and VRML up to now. The purpose of this research are to study how we apply VRML to the data to be acquired by close range photogrammetry and to evaluate the practicality of VRML for 3D image restitution of facilities. We used VRML and implemented the facilities with a 3D image. A research product VRML knew we ate the application very at a sincerity expression of the facilities.

Physicochemical properties of arrowroot starch were investigated. The starch had blue value of 0.397, alkali number of 10.1 and amylose content of 22.0%. The starch was practically insoluble in water up to $55^{\circ}C$. X-ray diffraction was C pattern, but was close to A pattern. The alkali number, X-ray pattern and viscogram of the starch and retrogadation rate of the starch gels indicated that the properties of the arrow root starch were close to those of cereal starches.

According to John Newman's Bibliography of Imaginative Works about American Fighting in Vietnam, there are 1370 entries up to 1996 which deal with the theme of Vietnam War in literature. Among various themes such as war and gender/race and ethnicity/class, this study makes an issue of the contiguity between femininity and death in Vietnam War novels written by Americans to investigate one of the bedrocks upon which the western civilization is founded. Female figures, especially Oriental females are seen as an emblem of death in the novels such as The Thirteenth Valley, Close Quarters, Body Count, and Bamboo Bed. It has been found out that this kind of death obsessive mode of thinking is deeply embedded in Western mentality and argued that its habitual mode needs to be changed.

In manufacturing the all-ceramic crown whick look close to natural teeth, the effectiveness of the improved technique is expectected the technique of the heat treatment of gold plating coating die was experimented of a refractory cast model. The following results were obtainde 1. An advantage of build up on east die with out manufacturing veneer, crown, core, or masking(reduction of technical process, and retrenchment of time and money) 2. Esthetically more close to natural teeth than other technique 3. Easy to remove a refractors cast die 4. In manufacturing ceramo-metal crown the enomous effectiveness was obtainde on applying in the areas of cervical margin, the metal surface, and in the treatment of pinhole.

The stability of a simply supported straight pipe is investigated. The time dependent flow is assumed to vary harmonically about a constant mean velocity. Stability conditions and dynamic reponses of a governing equation are conducted by use of multiple scale mettled. Parametric resonances and combination resonances are investigated. Stability boundaries are analytically determined. The resulted stability conditions show that instabilities exist when the frequency of flow fluctuation is close to two times the natural frequency or to the sum of any two natural frequencies. In case that the fluctuated flow frequency is close to zero or to the difference of two natural frequencies, however, instabilities are not found up to the first order of perturbation. Stability charts are numerically Presented fir the first two vibration modes.

Caudal regression syndrome (CRS) is a rare neural tube defect that affects the terminal spinal segment, manifesting as neurological deficits and structural anomalies in the lower body. We report a case of a 31-month-old boy presenting with constipation who had long been considered to have functional constipation but was finally confirmed to have CRS. Small, flat buttocks with bilateral buttock dimples and a short intergluteal cleft were identified on close examination. Plain radiographs of the abdomen, retrospectively reviewed, revealed the absence of the distal sacrum and the coccyx. During the 5-year follow-up period, we could find his long-term clinical course showing bowel and bladder dysfunction without progressive neurologic deficits. We present this case to highlight the fact that a precise physical examination, along with a close evaluation of plain radiographs encompassing the sacrum, is necessary with a strong suspicion of spinal dysraphism when confronting a child with chronic constipation despite the absence of neurologic deficits or gross structural anomalies.

Chronic obstructive pulmonary disease (COPD) affects close to 400 million people worldwide. COPD is characterized by significant airflow limitation on spirometry. Most patients with COPD are diagnosed in their fifth or sixth decades of life. However, the disease begins much earlier. By the time airflow limitation is detected on spirometry, patients with COPD have lost close to 50% of their small airways. Thus, identification of patients with early COPD, defined as persons with preserved spirometry, who demonstrate pathologic or functional hallmarks of COPD, is essential for disease modification and ultimately disease elimination. This paper provides an up-to-date overview of the current case definition of early COPD, its importance, the novel technologies required for its detection in young adults and future directions in therapeutics for treatment.

In this paper, we propose the method that decides the shot types using face detection technique. The shot types, such as close-up shot, medium shot, and long shot, can be applied as useful information for understanding narrative structure of movies. The narrative structure of movie is builded by characters. Also their mental and emotional changes become inextricably bound up with them of narrative. The shot types are decided by distance between character and camera. If put together above them, shot types can be found by using detection technique of face size of characters and understand narrative of movie. To do this, we propose the methodology to detect shot type by face detecting and implement the system to do it. Additionally, we evaluate the performance of the system. The implementation system has been evaluated as 95% for close-up shot detection and 90% for medium shot detection, while 53.3% is just detected for long shots.
