Recently the uncertainty has been made rapid progress in various fields of industry but the uncertainty measurement method of acoustical test (i.e. Insertion loss, Absorption ratio, Transmission loss etc,) hasn't been established. In this study, the uncertainty of measurement method for ducted silencers is carried out according to ISO 7235. The standard uncertainty factors are composed of sound pressure level, microphone sensitivity and pistonphone calibration in this measurement. Sound pressure level is type A evaluation of uncertainty, microphone sensitivity and pistonphone calibration are type B evaluation of uncertainty. The combined standard uncertainty is calculated by two type evaluation. The expanded uncertainty is expressed by the combined standard uncertainty multiply k value which is yield the effective degree of freedom.

This paper presents a high-speed pulse-based flip-flop with pseudo MUX-type scan compatible with the conventional master-slave flip-flop with MUX-type scan. The proposed flip-flop was implemented as the standard cell library using Samsung 130nm HS technology. The data-to-output delay and power-delay-product of the proposed flip-flop are reduced by up to 59% and 49%, respectively. By using this flop-flop, ARM11 softcore has achieved the maximum 1GHz operating speed.

The foot shape from the right and left feet was taken with 78 male and 213 female Korean subjects. The results are as follows. 1) Mean values and standard deviations of 25items concering the foot : Measurements performed on Korean adults(male and female) show that male left foot length is in average somewhat longer than the corresponding right foot length(25.35Cm against 25.32Cm) and on the contrary that the circumference of the left foot is slightly smaller than for the right foot. For the same tendency is verified in female feet. 2) Correlations between measurement items : Finding a correlation of more than 0.08 only between the foot length to suggest that the present system of ready-made "shoe" size system, based only on foot length, is not a quite appropriate system. 3) Distribution between foot width, foot girth, instep height and foot length : Foot length showed from 21.52Cm to 24.0Cm in the female subjects and from 24.0Cm to 26.5Cm in the male subjects for the standard type. Foot width showed from 7.5Cm to 10.0Cm in female and from 8.5Cm to 10.5Cm in male for the standard type.dard type.

In order to investigate the complaint rates of subjective fatigue symptoms and study the relationship between them and body type, health awareness in middle school students, we carried out a survey of 1,209 students (654 boy students and 555 girl students) at a middle school in Taejon City by a self-recorded questionnaire. The survey was conducted in June, 1997. The results obtained were as follows: 1. Among complaints of fatigue, "feel like lying down" was the highest, followed by "feel anxious about things", "feel drowsy", "yawning a lot", "eye strain" and "whole body feels tired" in descending order. 2. In the average weighted score of fatigue complaint, dullness and sleepiness (I) was the highest, followed by a difficulty in concentration (II) and bodily projection of fatigue (III) in descending order. Fatigue seems to create mental stress rather than physical burdens. 3. In the classification of body type based on the $R\ddot{o}hrer$ index, the obesity type (145 and above) was 11.0%, standard type (110~144) was 64.7% and leptosomic type (l09 and below) was 24.3%. Comparison between both sexes revealed that the rate of obesity and leptosomic types were significantly higher in boy students than in girl students. 4. In terms body type awareness, the statistics are the following: those who consider themselves to be standard type, 44.3%, slightly obese 24.5%, leptosomic, 23.5% and obese 7.8%. However, the level of obesity awareness was significantly higher in girl students than in boy students. 5. As for health awareness, 36.5% considered themselves healthy, 5.4% generally healthy and 10.1% a little unhealthy, but the level of unhealthy awareness was higher in girl students than in boy students. 6. In the relationship between body type and health awareness, most students thought that they were obese in spite of their standard body type. Also, many students who were obese and leptosomic tended to consider themselves to be a little unhealthy. 7. The more the students were obese or felt unhealthy, the more the average weighted score of fatigue complaints was high.

As an attempt to improve the seaming of clothes exported to China, this study is intended to strengthen the clothing industry in Korea by providing data on the body figures of Chinese women. Direct measurement was conducted on 193 women aged 19-24 residing in Shanghai, China. Then we classified and identified the body types and characteristics of Chinese women based on the drop values suggested by the National Standard of the People's Republic of China(GB/T 1335.2-1997). The following is a summary and conclusion of this study. 1. The following results were obtained by measuring the body sizes of women aged 19-24 living in Shanghai, China. 2. After having conducted a factor analysis on 111 body measurement items, 15 index items, and 11 calculation items, we were able to deduce a total of 6 factors. 3. We categorized the body types of 19-24 year-old women living in Shanghai, China according to the drop values suggested by GB/T 1335.2-1997 where D-type was added to Y, A, B, and C-types for a total of 5 categories. The characteristics of each body type following the body type structure factor are Y-type for slender type, A-type for standard type, B-type for slightly large type, and C-type for obese type.

This research aimed to suggest a standard design that reflects Hanok design tendency, and present a selective design that can fulfill a building owner's intention beyond the simple function of building permit or report. In addition, this research attempted to become a standard by establishing a criterion in calculating the measurements of section design or primary framework members, in order to be a guideline for designing Hanok in different sizes and forms. The results are as follows. The building area of Hanok standard design was set to be below $85m^2$, with a straight type of $83.16m^2$ and an L-shape of $84.24m^2$. By dividing the plane into a straight type and L-shape, two straight types were suggested: 'general type' and 'large living room type.' The upper floor space, along with the main room and small room, was proposed as an option to be changed into a room where an underfloor heating is installed depending on the building owner's intention. In addition, a criterion for side design and calculation of framework measurements was suggested and applied, while a five-girder design without high pillars was suggested for material-assembling structure. Two types of pillars-circumference and square cylinder-were proposed for the building owner to choose from, and a pointed beam house and ikgong(orthogonally-projected bracket) house were suggested for pojak bracket structure so either of them could be chosen according to the building owner's taste and economic condition. Finally, the sectional size of main materials were divided according to the form of pojak bracket structure to be proposed.

It is important to develop standard metadata to give more plentiful information about the forest cover type map and to promote distribution by National Geographic Information Clearinghouse. In this study metadata for the forest cover type map was designed based on TTAS.IS-19115 and it consisted of 10 packages and 50 elements. Also metadata editor was developed to implement metadata with standard schema and metadata viewer to service more user friendly interface. This work was about the first standard metadata for forest GIS data. So it would be a useful reference to develop metadata for other digital map concerning forest.

Because the rain gauges of tipping bucket type can easily use the digital signal, the rain gauges are widely used for the meteorological observation. In general, the resolution of rain gauges of tipping bucket type can be categorized by the 0.1mm, 0.5mm, and 1.0mm classes. But, the error of the tipping bucket rain gauges is made by the intensity of rainfalls and is expected to make the standard calibration method for error measurement. Thus, we developed the hardware of standard calibration facility for rain gauges by weighting measurement method and proposed the standard procedure by rainfall intensity in this study Also, we calculated the error for the rainfall intensity and obtained useful result through the proposed calibration method.
