  • The purpose of this study is to find optimal conditions for various outlet clearances of prototype garlic clove separator with a rotating cone in the constant inlet clearance and cone height. Optimal outlet clearance from medium to small size garlics was 25 mm at the $200{\sim}400rpm$. For large garlic, optimal outlet clearances of Namdo and Uiseong garlic were 34 mm and 37 mm, respectively, in the range of $300{\sim}400rpm$. The proportion of garlic separation was over 95% for all quality of garlics. The proportions of damaged garlics at 25 mm and 28 mm outlet clearances were below 5% and below 10%, respectively. Therefore, in order to maintain high performance of garlic separation for the various varieties and qualities, the rotating cone type separator should be designed with cone speed ranges of $200{\sim}400rpm$ and the outlet clearance ranges of $25{\sim}37 mm$. The outlet clearance of the separator should be easily controlled within those ranges.

  • Normally, multiple socket-outlet is manufactured with soldered, welded permanent connection (termination). Because this procedure is very non-environmental and requires many labor forces, many companies skip this process. To solve this these problems, this research had to design permanent joint type multiple socket-outlet, develop safer multiple socket-outlet than is sold in markets. Progressing this research, we took 3 steps. First, we had to design device for fixing a frame suitable for multiple socket-outlet. Second, this multiple socket-outlet must pass fundamental standards through international standard (IEC 60884-1) and Korean standard (K 60884-1) tests. Third, it had to pass both several mechanical and electrical tests which is more strict than fundamental standards and vibration and impact tests following KS standards for enhancing its safety. After finishing 3 steps, we could obtain objective and fair data, develop environmental permanent joint type multiple socket-outlet without soldering crimped connection.

  • Generally, the phase of the refrigerants that circulate in air-conditioning systems is repeatedly changed from liquid to gas and from gas to liquid. In vapor-compression refrigeration, the refrigerant at the inlet of the evaporator is in a gas-liquid two-phase state; therefore, to enhance the heat-transfer performance of the evaporator, the even distribution of the refrigerant across multiple passages of the evaporator is essential. Unlike the distribution of a single-phase refrigerant, multi-phase distribution requires further considerations. It is known that the multi-phase distribution at the outlet of the distributor is affected by factors such as the operating condition, the distributor's shape, and the insertion depth of the outlet pipes; here, the insertion depth of the outlet pipes is especially significant. In this study, for a cylindrical distributor with a 90-degree bend entrance and three outlet pipes, the flow uniformity at the outlet pipes was numerically tested in relation to variations of the insertion depth of the outlet pipes.

  • In this paper, we manufactured waterproof outlet that use silicon packing know-how. Developed outlet is waterproof packing on pins of the plug insertion hole and electric wire insertion hole. Therefore, outlet body internal furnace water can prevent that is flowed in. Temperature anomaly can use in back large outer wall, restaurant exposed easily to moisture, bathroom, laundry, a laboratory and science room, auditorium, etc. That is estimate that contribute on courtesy call of electricity calamity.

  • Thoracic outlet syndrome presents with symptoms resulting from pressure on either the subclavian vessels or the lower trunk of the brachial plexus. It may be caused by a number of abnormalities, including degenerative or bony disorders, trauma to the cervical spine, fibromuscular bands, vascular abnormalities, and spasm of the anterior scalene muscle. We experienced a case of thoracic outlet syndrome [ caused by cervical rib .We report a case with review of literatures.

  • Thoracic Outlet syndrome is defined to compression of the subclavian vessels and brachial plexus at the superior aperture of the thorax. It was previously designed due to presumable etiologies such as scalenus anticus, costoclavicular, hyperabduction, cervical rib or first rib syndromes. We experienced a case of thoracic outlet syndrome[scalene anticus syndrome] .Patient has been suffered from swelling and numbness of the right forearm and hand for 2 years. Diagnosis was made by preoperative selective angiography. Scalenus anticus and medius muscle resction and first rib resection was done with transaxillary approach. Postoperative course was not eventful.

  • This study was to examine the factor structure of pursuing benefit and satisfaction at casual and official wear, to analyze the differences of pursuing benefit, satisfaction, and clothing purchase behavior among the consumer groups segmented by store pursuing benefits, and to provide useful information for establishment of marketing strategies. The subjects were 500 female consumers experienced in purchasing clothes at fashion outlet stores. A total of 500 questionnaires were analyzed with $X^2$-test, ANOVA, factor analysis and Duncan's multiple range test. The results were as follows: 1. Pursuing benefit and satisfaction at casual wear and official wear were composed of 5 factors. 2. Pursuing benefit and satisfaction at casual and offcial wear, and clothing purchasing behavior variables such as informants, frequency of purchase, shopping time, and average monthly expenditure on clothes were significantly different among the 3 segmented groups. Product pursuing group was shown to seek higher level of esthetic feeling, suitability for self image and body, fsshion and symbolic meaning of brand than other groups in casual and official wear and to be most satisfied at symbolic meaning of brand, social recognition, and practicality in casual wear of outlet and at suitability and social recognition in official wear of outlet. Store convenience pursuing group was shown to seek higher level of suitability for self image and body, quality, and practicality than other groups in casual and official wear and to be most satisfied at quality and practicality in casual wear of outlet and at practicality and suitability in of cial wear of outlet. Price pursuing group was shown to seek and to be most satisfied at practicality in casual and official wear of outlet.

  • Nonlinear adaptive control for the laboratory pressure-flow model. Control valves are installed on both sides. The pressure and the outlet flow rate are measured. The pressure and outlet flow rate are controlled variables and the control valve stem positions on both sides are the manipulated variables. The variation in both inputs will influence both controlled variables. The control performance is good, in spite of varying valve coefficients of inlet and outlet.

  • Because of overload working condition of sintering cooler, the cooler fan often suffers the break or damage of rotor blade and fixing shaft. Therefore, internal flow characteristics of a steelworks sintering cooler fan by the duct shape of the cooler fan outlet, such as duct outlet opening ratio, duct height and dividing wall shape on the duct outlet flow pattern are examined in detail. The results show that relatively short duct wall height and attachment of dividing wall shape improves flow patterns considerably.

  • This paper analyzed the characteristics of heat transfer in quadangle duct with absorber plate by solar radiation. Effects o( Reynolds number on increasing temperature at outlet for variation of absorber plate temperature were analyzed by using numerical analysis technique. And also the effects of turbulent intensity of inlet flow on increasing temperature at outlet for various duct height and effects of inlet aspect ratio of quadrangle duct and position of heating surface on the outlet temperature were analysed. As the results, Outlet temperature was greatly influenced in low Reynolds number. And the highest outlet temperature distribution appeared on the inlet aspect ratio 2 because of the buoyancy effect.
