This study is to compare the pattern making methods of men's jeans and to analyze sizes of parts while also evaluating the appearance and fit according to a 3D virtual garment simulation. Five types of patterns are selected for the analysis. For the appearance evaluation, the study conducted a virtual clothing simulation, created a perspective drawing, and applied Clothing pressure to each test outfit. First, according to the pattern comparisons, A and D had the shortest crotch length, while B had the longest; B had the narrowest crotch width, while C had the widest; C had the greatest waist circumference, and B had the smallest; C had the greatest knee and hem circumference, while E had the smallest. Second, according to the appearance evaluation, E pants had the highest rating overall for the waist, crotch, knee, and hem comfort; A pants had the highest rating for the yoke line end and placement; and C pants had the highest rating for the side seam line. According to the correlation analysis, ease of the waist, hips, hem and thighs were important factors (in that order) in determining the overall appearance of the jean pants.

In order to improve occupant protection in frontal crash, the IIHS introduced a small overlap frontal crash test in 2012. When the front corner of a car collides with another car or object, such as utility pole the test replicated the sequence of events. Because occupants move simultaneously forward and toward the side of the vehicle this test is challenging for some airbag and safety belt designs. In the small overlap frontal test, a car travels at 64 km/h toward a rigid barrier. A hybrid III dummy is positioned in the driver seat. 25% of the total width of the car strikes the barrier on the driver side. After review of small overlap frontal test protocol and overall rating, six run-throughs were performed according to the original test method.

The object of this study is to examine the informational effect of the rating change announcement on the capital market. For this study, daily stock prices from January 1993 to February 2001 and daily bond prices from July 2000 to February 2001, for the bond market are used. In the stock market, we could not observe any statistically significant stock price reaction to rate change announcements from July 2000 to February 2001. However, if rating agencies announce more than two degradation for the period of January 1993 to February 2001, statistically negative significant stock price reactions are observed. On the other hand, there is no statistically significant stock price reaction to any other rating change announcement. In the bond market, there is no statistically test on the bond price reaction, but the general directions of bond price movements are consistent with the effect we can expect from rating change announcements. Generally, when the rating agencies degraded more than two grades at once, a cumulative abnormal returns move negatively during the overall period. In this case, we can say that rating agencies' role is to confirm information or investor's expectations. However, for the other cases, we could not observe my significant movement before or on the event data.

The rating curve is required to convert measured stage into a discharge and is developed using the measurement. In the development of the rating curve, the segmentation position is determined by considering the hydraulic characteristic and channel shape, and subjective judgment of the Hydrographer may intervene in this process. The segmentation position is so important that it determines the overall form of the rating curve, and the incorrect segmentation can cause errors in the rating curve, especially in extrapolation. In order to develop an accurate rating curve with a small number of measurements, the sections must be divided by considering hydraulic characteristic such as the cross-sectional shape. In this study, hydraulic examination methods such as stage-mean velocity, stage-area, stage-${\sqrt{Q}}$ investigated and supplemented to eliminate subjectivity in segmental positioning. Appropriateness for the segmentation position was verify in consideration of the physical meaning of the rating curve index (c).

The purpose of this study was to assess the sedative effect of three kinds of medication for management of the uncooperative 60 children aged from 16 months to 87 months required extensive treatment. The patients were given randomly a dose of 75mg/kg of chloral hydrate and hydroxyzine 25mg orally or 0.5mg/kg of midazolam orally or 0.3mg/kg of midazolam intranasally. All the children were restrained in a Pediwrap and were monitored with Pulse oximeter for assessing the safety of patients. According to rating scale, sleep, crying, movement, and overall behavior were checked for evaluation of the clinical sedative effect. The results were as follows: 1. In the evaluation of sleep, rating scale of chloral hydrate/hydroxyzine was superior to the other group(p<0.05). 2. In the evaluation of crying and movement at beginning of treatment, rating scale of chloral hydrate/hydroxyzine was superior to the other group(p<0.05), but during the treatment, rating scale of each group was not significantly different (p>0.05). 3. In the evaluation of overall behavior, 80% children of chloral hydrate/hydroxyzine were rated good or very good. With the oral and intranasal midazolam, 60% children were rated good or very good respectively. 4. There were no clinical signs of significant cyanosis and respiratory depression. Clinically, chloral hydrate/hydroxyzine was proved to be more effective sedation than any other sedative method. Oral and intranasal midazolam were also safe and effective sedation in young children undergoing pediatric dental procedures.

It is the purpose of this paper to describe the methods for establishing loudness ratings and talker echo out of transmission quality of ISDN telephone connected to fully digital network. In order to design the desirable loudness ratings and talker echo for ISDN telephone, the model system of digital speech communication for subjective tests is developed. Using this model system, opinion tests which decide the optimal CODEC input level, the range of overall loudness rating, sidetone masking rating and talker echo are performed. From the results of tests, we decided that the loudness ratings are 6 to 8dB for sending, 0 to 2dB for receiving, and 8 to 12dB for sidetone masking rating. And, the terminal coupling loss of TCLw of at least 40dB is necessary to provide echo-free telephone communications to telophone users when the overall loudness rating of ISDN telephone is normalized to 10dB.

At present, in the case of small and medium window manufacturers in South Korea, glazing and window frame manufacturers are divided into separate businesses. However, in the fenestration energy consumption efficiency rating system and the energy-saving design criteria for buildings, the coefficient of overall heat transmission standard for windows is defined by window sets, which integrate glazing and window frames. At most construction sites, windows are constructed by installing separately supplied glass and frames. Research that can integrate the reality and the system is therefore necessary. The present study first investigated and analyzed the on-site situation of the fenestration energy consumption efficiency rating system. According to the results, while overall understanding of the fenestration energy consumption efficiency rating system was high, satisfaction with it was low, and the general practice at construction sites was to use windows assembled on site rather than integrated window systems manufactured at factories, thus making it difficult to confirm that the current rating system was well applied on site. Consequently, the reality of industrial sites must be reviewed and a realistic alternative to the fenestration energy consumption efficiency rating system must be presented instead of focusing on theory.

This study presents the results of our analysis and recommendations for process and productivity improvements. The project studied consists of a 5-story research building, with a structure of steel frames supporting concrete slabs. The observations focused on the analysis of the overall erection and framing process. The methods used for the analysis consisted in intensive visits on site, where construction processes were observed in term of resources, activities, durations, materials' handling procedures, and technology used. Back to the office, authors used the information captured to model the different trades' activities, using work sampling and 5-minute rating technique. The work sampling provides insight into the activity, hence allowing for process improvements. The productivity of various trades is strongly dependent on the organization of the work process and work site conditions. Improving the productivity of the entire project or company is not possible until everyone is committed to improvement.
