The purpose of this study was to investigate proportional characteristics of soft tissue profile in Korean young adults. The sample consisted of 50 young adults(25 males and 25 females) who had pleasing profile and normal occlusion. Soft tissue proportional analysis was performed on lateral cephalograms taken in natural head position. The results were as follows : 1. Mean and standard deviation of proportional analysis were obtained. 2. Horizontal and vertical dimensions were larger in male. But facial proportion had no sexual difference except upper/lower face height (p<0.05). Upper/lower face height was larger in female than in male. 3. Vertical dimensions, except SN-ST, had high correlation with horizontal dimensions. 4. Head positioning error of natural head position was smaller than inter -individual variability of SN line.

Electro Otical Tracking System(EOTS) is required for a rapid movement as well as the stabilization of Line-Of-Sight(LOS). In order to achieve these two goals, this paper presents a position and velocity driving profile generation method from the constant acceleration and deceleration profile according to the current state, enabling a fast and smooth trajectory even if the target position changes during the movement of LOS. Simulation and experimental results reveal that the settling time could be reduced significantly by adopting the present position control scheme.

The performance of screw compressor depends on lots of design parameters of rotor profile, such as length of seal line, wrap angle, blow hole, suction and discharge port size, number of rotor lobe, etc. The optimum rotor profile makes it possible to increase the compression efficiency with low energy consumption, and to minimize the loss of power. In this research, a new rotor profile design and performance analysis are done by computer simulation. It is expected that the volumetric efficiency is improved because the internal leakage is reduced due to the minimization of blow hole and clearance, and the stiffness of rotors is increased due to the reduction of length to diameter ratio. Also, the specific power consumption will be secured for use ranging from low to high operation speed.

Purpose The purpose of this study is to analize a psychological and behavioral mechanism for using profile picture management in digital service such as social network service. Profile picture management falls under metadata management and is performed only by those who want it. This means that it, is one of the typical makeup-type digital shadow works (DSWs) which have not been studied yet. Design/methodology/approach This study adopts ground theory method(GTM) as research methodology. GTM, which is one of qualitative methodologies, is for developing theories while most survey based methodologies, which are well adopted in much research for information systems, are for validation of theories. By interviewing ten users, the data are collected and analyzed by open coding, axis coding with paradigm model, and selective coding. Findings In result, 39 codes are found and classified into 29 sub classes and 15 classes. These 15 classes are organized by paradigm model which derives core code of profile picture management as 'voluntary management tasks to experience small pleasures with intermittent attention'. Finally, based on the paradigm model and the core code, the story line, which can explain profile picture management, is suggested.

This study suggests an algorithm for tooth profile generation of free from curve involute gear, a special gear of which the pitch line is a free curve instead of a circular one. For the first, a methodology for calculation of the tooth curve is developed and formulated Then the formulated algorithm, is programmed for manufacturing and verified by computer graphics. Next the calculated results as changed in to NC codes to apply to wire electric discharge machine(WEDM). Finally, the machined gear is examined in engagement with a standard involute gear.

A hydrostatic model atmosphere of a typical umbral core is constructed on the basis of both Na I $D_2$ line profile and umbral core-to disk continuum intensity ratio. The observations were obtained by Mullan and Wyller with photoelectric means over the range from $4000{\AA}\;and\;6500{\AA}$. The computed line profile of Na I $D_2$ and the emergent continuum intensity distribution are compared with the observations. The temperature of umbral cores is found to be lower by $300^{\circ}K\;to\;500^{\circ}K$ than that of their ambient umbral region. The detailed physical structure of a working model of umbral cores is proposed.

The rolling-stocks used in conventional line have suffered wheel problems due to lack of adaptability with track. These brought out severe wheel flange wear, these have caused unstable ride characteristics of rolling-stock. Especially, Wheel flange wear is severely influenced by wheel profile but lateral suspension characteristics. This study was started to induce wheel profile suitable for domestic railway environment. Thus, we analyzed the wear characteristics of wheel profiles that are being applied to railway rolling-stock in KNR. To analyze wheel wear characteristics, we have conducted experiment studies for passenger rolling-stock and obtained useful datum.

Fiber optic distributed temperature sensing and thermal line sensor are applied in an observation borehole and a loom deep borehole heat exchanger. For the case of permanently installed system fiber optic DTS is very useful. By comparing with TLS, fiber optic DTS shows good accuracy and reliability. Ground water flow can give influences at heat exchange rate of the heat pump system. According to the hydraulic characteristics and temperature-depth profile, we consider that temperature-depth profile do not seem to be dependent on ground water flow. A permanent installation of fiber optic cable is expected as a reliable temperature measurement technique in a borehole heat exchanger system.

I present a 3-D profiler specially devised for the profile measurement of specular surfaces that requires precision shape accuracy up to a few nanometer. A profile is reconstructed from the curvature of a test part of the surface at several locations along a line. The local curvature data are acquired with White-light Scanning Interferometry. Test measurement proves that the proposed profiler is well suited for the specular surface inspection like precision mirror.

Background: Detection of antibodies to extractable nuclear antigens (ENAs) is needed for the diagnosis in systemic autoimmune diseases. In this study, we compared three reagents using line immunoblot assay (LIA) or multiplex bead immunoassay for detecting the anti-ENAs. Methods: A total of 89 sera were tested by 3 different assays: EUROASSAY Anti-ENA Profile (Euroimmune, Germany), Polycheck Autoimmune Test (Biocheck GmbH, Germany), and $FIDIS^{TM}$ Connective Profile (Biomedical Diagnostics, France). The following individual ENAs were investigated: Sm, SS-A (Ro), SS-B (La), Scl-70, Jo-1 and RNP. We reviewed medical records to investigate the discrepant results among three methods. Results: Overall percent agreements were 96.1% between EUROASSAY Anti-ENA Profile and $FIDIS^{TM}$ Connective profile; 90.4% between EUROASSAY Anti-ENA Profile and Polycheck Autoimmune Test using the manufacturers' cutoff; 96.4% between EUROASSAY Anti-ENA Profile and Polycheck Autoimmune Test using a upward cutoff; 90.4% between $FIDIS^{TM}$ Connective profile and Polycheck Autoimmune Test the manufacturers' cutoff; and 96.4% between $FIDIS^{TM}$ Connective profile and Polycheck Autoimmune Test a upward cutoff. Conclusions: The three assays showed excellent agreement with each other. With appropriate cutoff, the all three assays for six of the anti-ENA tests investigated in this study can be used in clinical laboratories for detecting the anti-ENAs.
