Screen printing technique followed by firing has commonly been used as metallization for both laboratory and industrial based solar cells. In the solar cell industry, the firing process is usually conducted in a belt furnace and needs to be optimized for fabricating high efficiency solar cells. The printed-Al layer on the silicon is rapidly heated at over $800^{\circ}C$ which forms a layer of back surface field (BSF) between Si-Al interfaces. The BSF layer forms $p-p^+$ structure on the rear side of cells and lower rear surface recombination velocity (SRV). To have low SRV, deep $p^+$ layer and uniform junction formation are required. In this experiment, firing process was carried out by using conventional tube furnace with $N_2$ gas atmosphere to optimize $V_{oc}$ of laboratory cells. To measure the thickness of BSF layer, selective etching was conducted by using a solution composed of hydrogen fluoride, nitric acid and acetic acid. The $V_{oc}$ and pseudo efficiency were measured by Suns-$V_{oc}$ to compare cell properties with varied firing condition.

This paper presents a fast back-type transfer device for snack food processing that uses the inertia of transferred material. A conventional conveying system is a drive system that uses a belt conveyor and mechanical crank, which generate noise and vibration and cause environmental pollution. Vibration and noise are reduced in the proposed fast back feeding device by using a counterweight. The crank drive unit was replaced with a linear servomotor, and an equilibrium device was designed to balance the force due to acceleration. This makes it is possible to adjust the forward and backward speed and acceleration through PLC control. A vibration damper device offsets the vibration force of the periodic shock form. The main cause of the vibration was identified through vibration analysis, and reduction measures were established. We verified the effectiveness of the vibration by making a prototype and performing about 10 vibration tests. Because no mechanical transducer is needed, energy loss, noise, and vibration do not occur, and the operating speed is not limited.

Ordinarily hair styles and headclothes show the racial characteristics. Uighur's men had let their long hair hang down their back in many queues, According to the order of estates men wore double high coronets hthree-pointed coronets from the headdress. Married women wore the felt headdress. The type of men's clothes were long caftans which had a round collar slits on the both sides and tight sleeves. They tied Chan Die belts and wore long boots. Women wore long tunics with everted collar which was decorated. Later the type of women's dress was changed into the long caftan. Late period of Turfan Uighur Mongol style had appeared.

When compose magnetic field curer by belt and band style and need by magnetic field ripple last month, produce self-discipline roof. Bred in muscle disease (lumbago, backbone disease, corpulence) back. Result that study, manufactured various variableness band style - magnetic field probe firstly. Can establish self-discipline treatment pulse price by disease secondly. Could seek correct variableness band punishment, - magnetic field probe relationship implementation and property in waist, and so on, shoulder, neck, arm, leg, ankle, wrist etc. by third. Could find variableness band style energy value that need in-magnetic field Probe's treatment by fourth. This research could design pulse of self-discipline in band form and apply each according to disease.

This study aims to analyze the characteristics and styles of wearing scarves in the contemporary fashion. Scarf-wearing styles found in the contemporary fashion are as follows: 1) Scarves are used as gorgeous hair accessories which are tied around the head like a headband, turban. 2) The second style is to wear scarves around the neck, which involves a variety of ideas. 3) Shawl-like scarves add elegance and femininity to any outfit when they are draped over the shoulders. 4) Scarves are also worn instead of or in addition to a belt with a dress, skirt, pants. 5) The style is to tie a scarf in knots at the back of the neck and the waist as it is shaped or in a diagonally half-folded shape. 6) You can tie a scarf to your hat or handbag or connect a long scarf to one part of your body.

1. In the late second century A.D. the dalmatic, which originated in Orient, came into fashion in the Roman world. 2. It was first introduced as a vestment in public worship by Pope Sylvester I (314-335A.D.) who ordered it to be worn by the deacons. 3. The dalmatic was cut like a tunic, but wider, and with wide short sleeves. It was worn without belt, and was characteristically decorated by the clavus. Its shape, which is the form of a cross, refer to the passion of Christ. It symbolizes joy, salvation and justice. 4. In early christian epoch, colors was found in the Bible. 5. Clavus running from the shoulders to the hem in front and back represented as 'The servant of God', and symbolized the Blood of Christ. With time, clavi change from simple stripes to decorative ones.

In Koryo Dynasty Pyonbokpo(便服抱) was worn by both sexes. There were four styles that was Yosunchollic, Dappo, Pol, Poll, of the men's Pyonbokpo(便服抱). Double breast style (重据形) was used for the adjustments of these clothes. Neckline and he-m line were substituted by rectangular collar (목판깃). The width and length of sleeves in Yosunch-ollic was tighter and shorter as general Po. Coat-string (Okgolum), side slit were used. Feminine Pyonbokpo (便服抱) had usually same style of men's one. There was one was back longer than front length. They wore it with or without a belt. Knot-button, Coat-string (Okgolum), White straight collar (DongJung), side slit were used.

Recently, Child safety has become one of the issue with Q10 dummy representing large child. The objective of this paper was to evaluate performance of three child restraints system (backless booster, high-back booster and without booster) by changing D-ring location in the rear seat. Sled tests were carried out with a Q 10 in 64km/h frontal impact. Before the dynamic sled tests, we assessed dummy positioning with difference in CRS types and height adjustment positions. Dynamic sled test results indicated that there is different performance of CRS types and belt routing. These test results will use as base line data for development CRS safety performance for Q 10.

In order to gather clues to surface mineralogy of asteroids, we classify their taxonomy based on their reflected spectra. It is remarkable that a large number of asteroids plotted in the proper orbital element space with distinct colors according to their taxonomic types reveal the dynamical evolution and the structure in the near-Earth space, the main-belt and beyond. Although we have ~1×10⁶ known objects, no more than ~3×10³ of them are properly classified taxonomically as visible-near infrared spectroscopy is costly. On the other hand, multi-wavelength broadband photometry in the visible region provides a rather inexpensive alternative tool for approximate taxonomy. Thus we have conducted multi-band observations systematically using Korea Microlensing Telescope Network (KMTNet) with BVRI and griz filters since back in 2015. We then applied aperture photometry with elliptical apertures to fit the trails of objects during the exposures, and classified them with the principle component indices of Ivezic et al. (2001). We will make use of our new, three dimensional asteroid classification scheme for the next step.

A virtual garment fitting system which fits the top and bottom of a garment on 3D body data is introduced. This system uses the laser scanned 3D body data and the digital images photographed the front and back of a garment. The digital images are modeled to reflect tensions among particles in the images and the friction and gravity effects are considered in the fitting process to the body data. When a bottom is fitted, a virtual belt to hold the bottom in the waist is introduced since gravity effects pull down it. Also the process for fitting the top and bottom on layers is proposed here. The system has the strengths that it uses only the front and back image of a garment instead of using complicated patterns of a garment, and provides a realistic fit result as a 3D figure. As on-line retailing shop in present displays front and back images of garments, this system also does. However this system provides a differentiated service to user than present retailing shop as showing a 3D fit image. It will make a new trend in online shop retailing of garment.
