  • Recently the importance of distribution channel design has been focused on due to a turbulent environment. The channel design strategy involves the choice of an optimal channel arrangement including channel width, channel depth, the types of intermediaries to be used, and the specific responsibilities of each channel member. The purpose of this paper is to investigate changes of distribution intensity in the infant & children's wear brand from 1997 to 1999, when Korea has faced changes before and after IMF intervention that influenced the Korean economy greatly. Thus, this study provides channel managers with some guidelines for establishing and adjusting the infant & children's wear channel strategies. The data is collected by the Korean Fashion Brand Annual published by Apparel News Co., from 1997 to 1999. infant & children's wear brands are selected and analyzed with Pearson correlation. Statistic analysis has shown different results in the type of brands in terms of distribution intensity. The type of brands between infant's wear and those for children differ in price and launching period. In the case of infant's wear brands, the launching period and total sales should be considered in designing channel distributions, while for children's brands total sales are significant. As the price increases, children's wear brands are significantly linked to their distribution intensity only in certain times at the starting point of IMF intervention. IMF intervention do not seem to influence the distribution intensity of infant's wear brands much as it did children's wear brands. It seems that the infant's wear industry is more stable than the children s wear industry. As a result, the marketer who plans distribution intensity for the infant's and children's wear brands should consider total sales, the launching period and the price according to the type of brands he deals with.

  • A characterization of turbulent reacting flows has proved difficult owing to the complex interaction between turbulence, mixing, and combustion chemistry. There are many types of time scales in turbulent flame which can determine flame structure. This counter jet type premixed burner produces high intensity turbulence. The goal is to gain better insights into the flame structures at high turbulence. 6 propane/air flames gave been studied with high velocity fluctuation in bundle type nozzle and in one hole type nozzle. By measuring velocity fluctuation, turbulent intensity and integral length scale are obtained. And sets of OH LIF images were processed to see flame structure of the mean flame curvatures and flame lengths for comparison with turbulence intensity and turbulent length scales. The results show that the decrease in nozzle size generates smaller flow eddy and mean curvatures of the flame fronts, and a decrease in Damkohler number estimated from flow time scale measurement.

  • 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.

  • Optical triangulation displacement sensors(0TDSs) are widely used for their simple struchlre, high resolution, and long operating range. However, there are several factors that must be taken into account in order to obtain high accuracy and reliability Measurement errors from inclinations a? an object surface, prohe signal fluctuations generated by speckle effects. power vanation of a light source, electronic noises, and so on. Previous models of OTDSs can not show reasonable behavior as change of surface inclination and shape of light intensity distribution on the detector. In this paper, we propose a new and reasonable modeling for diffise-type OTDSs based on a geometrical optics. To verify propriety of new modeling, we take basic experiments. Shape of light intensity distribution is asymmetric in both simulation result and experimental result. Both simulation result and experimental result show same tendency of light intensity distribution movement as changing surface inclination

  • PURPOSE: The aim of this study was to review the effects of exercise intervention on blood glucose control in obese type 2 diabetic patients. METHODS: The PubMed and KERISS search engines were used and 61 papers that met the key questions were selected. RESULTS: Exercise is an effective intervention for the control of blood glucose in type 2 diabetic patients because it does not impair glucose transport in the skeletal muscle induced by muscle contractions. Insulin resistance, which is characteristic of type 2 diabetes, is caused by decreased insulin sensitivity or insulin responsiveness. Acute exercise improves the glucose metabolism by increasing the insulin-independent signaling pathways and insulin sensitivity in the skeletal muscle, and regular long-term exercise improves the skeletal muscle insulin responsiveness and systemic glucose metabolism by increasing the mitochondrial and GLUT4 protein expression in the skeletal muscle. CONCLUSION: The improvement of the glucose metabolism through exercise shows a dose-response pattern, and if exercise consumes the same number of calories, high intensity exercise will be more effective for the glucose metabolism. On the other hand, it is practically difficult for a patient with obese type 2 diabetes to control their blood glucose with high intensity or long-term exercise. Therefore, it will be necessary to study safe adjuvants (cinnamic acid, lithium) that can produce similar effects to high-intensity and high-volume exercises in low-intensity and low-volume exercises.

  • 선박용 SCR 시스템에서 유동 및 혼합특성을 개선하기 위해 상하유도 및 스월 형상의 혼합기가 고려되었다. 본 연구의 목적은 혼합기 구조에 따른 난류강도 및 균일지수(Uniformity Index)를 상세히 분석하여 SCR 성능을 개선하는 것이다. 그 결과, 촉매부 전단에서의 농도균일도는 혼합기를 사용하였을 경우 약 5% 개선됨을 알 수 있었다. 상하유도형 혼합기의 사용에 따라 주위에서 높은 RMS 수치 및 상대난류강도를 보이지만, 하류로 진행하면서 두 값은 감소하는 경향을 보였다. 스월형 혼합기의 경우 유동의 진행에 대해 RMS 수치와 상대난류강도의 감소가 비교적 적고 상대난류강도의 경우 상대적으로 균일한 분포를 보였다. 두 혼합기에서 발생하는 유동특성에 의해 혼합효과 및 혼합거리가 달랐음을 알 수 있었다.

  • PURPOSE: Strengthening training is effective at improving the function of stroke patients. This study was conducted to compare the effects of exercise intensity on walking, balancing ability, and blood glucose in stroke patients with type 2 diabetes mellitus and to suggest more effective exercise intensity for stroke patients. METHODS: Twenty-two patients with type 2 diabetes mellitus were divided into an experimental group (n=11) and a control group (n=11). In the experimental group, a 40-70% strength of 1RM exercise program was applied for 40 minutes a day, three times a week for 4 weeks. The control group received a 50% intensity of 1RM for the same number and duration of interventions as the experimental group. RESULTS: Both the experimental group and the control group showed significant improvement in the gait function, balance ability, and blood glucose level after the intervention compared to before the intervention. In the FGA (functional gait assessment), the experimental group showed a 52.4% greater increase than the control group, and the fasting blood glucose level was 16.7% greater in the experimental group than the control group. CONCLUSION: The strengthening exercise program, which gradually increases exercise intensity, seems to be effective at improving the function of stroke patients with type 2 diabetes.

  • 형광등용 조명기구에 사용되는 경명 반사판의 광학 설계 프로그램을 개발하였다. 이 프로그램은 조명기구 설계시간을 단축시킨다. SpeROD(Specular Reflector Optical Designer)는 2차원적인 조건들을 가지고 계산한다. 반사판 설계를 위해 고려되는 조건들은 목표배광, 반사판 그리고 Tangent Spiral Design 방법등이 있다. 본 논문에서는 SpeROD를 이용하여 지름 26mm(T8)의 형광램프와 폭 150mm의 반사판을 가지는 균일 배광 형태와 Bat-wing 배광형태의 반사판을 설계해보았다. 설계된 반사판의 형태에 대하여 배광에측 프로그램인 FIELD를 통하여 배광을 시뮬레이션 해 본 결과, 배광과 효율 면에서 만족스러운 결과를 얻었다.
