This paper presents the design guide of a LED red-light for naval vessels. Power consumption, luminous flux and optical characteristics of a conventional FL red-light were analyzed. Spectrum of the red-light is in ranges of 600~780 [nm]. Power consumption and luminous efficacy are 26.9 [W] and 1.1 [lm/W], respectively. From the experimental results, we proposed a 5 [W] LED red-light which save power consumption by 80 [%] and increase luminous flux over 500 [%].

제주지역에서 생산되는 대표적인 품종인 궁천조생과 흥진조생에 대한 품질에 관여하는 물리.화학적인 특성을 분석하였고 과일의 크기, 색깔, 생산지역에 따른 감귤의 맛등에 대한 관능검사를 실시하였다. 수확적기에 수확한 조생온주으 가용성고형물은 10.7, 11.0 였으며 산함량은 1.04%, 비타민 C함량은 41.19-44.94mg/100g였다. 당은 절반이 자당하이였고, 포도당과 과당이 각각 1/4씩 함유하고 있었다. 과일 크기에 따라 과중, 껍질두께, 가용성고용물, pH, 산함량, 산비는 각각 직선적인 상관관계를 가지고 있었으며, 경도와 과육율과의 유의성은 없었다. 관능검사 결과 중간정도의 크기의 감귤을 선호하며. 껍질의 색깔은 진한 홍등색일수록 선호하고 있음을 알 수 있었다. 또한 같은 품종이라고 할지라도 재배적지에서 생산된 감귤일수록 선호도가 높아 직선적인 유의성을 보였으며, 과즙의 경우 당산비가 높을수록 성호하여 고품질 감귤생산을 위한 노력이 필요한 것으로 여겨졌다.로 여겨졌다.

The Silicone tracheal T-tube was designed to maintain an adequate tracheal airway as well as to provide support in the stenotic reconstituted or reconstructed trachea. This report is our experiences with using silicone T-tube which were successfully used to two cases with extensive laryngotracheal trauma, and one case with decannulation difficulty for 9 months. Authors strongly believe that silicone T-tube is an excellent device out of consideration for our experienced cases, though many techniques have been applied for the treatments of tracheal problems.

This study is the visually emotional identification lighting for easy to distinguish using 3colors LED on AtoN facility in shore and harbor, which have realized a controller for certainly express the mouth of a harbor by red light and green light of both sides a harbor and for synchronization at a time of right and left or serial sequential the harbor guidance light through synchronizer or timer by GPS. There is expectation effect that is prevent a confusion about distinguish of facility by ship's operator and to beautify a night scene of harbor, which is expressed to emotional identification lighting differ from great many lighting of harbor with variable color lighting the lighthouse body and vertical layer color lighting using LED. The function of AtoN is adapted that guidance light through synchronization or serial sequential lighting and display of harbor safety message by CW lighting, and this system is the power consumption greatly reduce by candle alternated high light LED.

This study on the methode is easied to distinguish with emotional visual lighting on AtoN facility using 3colors LED, and which is controlled to on-off switching of approach light in shore or harbor. The identification have easied to provide a differentiation between the AtoN facility of red and white light and surrounding light in harbor both sides. And the integrated controller have designed to left-right and serial sequential lighting system for harbor guidance using the GPS synchronous or timer. There is expectation effect that is prevent a confusion about distinguish of facility by ship's operator and to beautify a night scene of harbor, which is expressed to emotional identification lighting and variable color lighting on AtoN body by vertical layer color lighting using LED. In addition, the performance of AtoN is implemented to display with guidance light the harbor safety message by morse code lighting. Effectiveness of system is enhanced that age and power consumption reduce by candle alternated high light LED.

This study is the visually identification lighting for easy to distinguish using colors LED on AtoN facility in harbor gate, which have realized a controller for certainly express the gate of harbor by red light and green light of both sides a harbor and for synchronization at a time of right and left or sequential the harbor guidance light through synchronizer or timer by GPS. There is expectation effect that is prevent a confusion about distinguish of facility by ship's operator and to beautify a night scene of harbor, which is expressed to identification lighting differ from great many lighting of harbor with variable color lighting the lighthouse body and vertical layer color lighting using LED. Especially the function of AtoN is displayed for harbor safety message by CW lighting, and this system is the power consumption greatly reduce by candle alternated high light LED.

The chemical components and quality of Takjoo mash were examined on the product brewed by the case of commercial amylase, Lactobacillus bulgaricus and the yeast. 1. Lactic acid was produced at the range of 917~1,350 mg per 100 ml of the mash brewed using wheat flour, corn flour, rice and pressed barley, while succinic acid was formed at the range of 6~32 mg per 100m1 of the mash. 2. Citric acid was formed at the concentration of 6.5mg per 100m1 of the mash on the use of pressed barley, and malic acid formed at the concentration of 1.7 mg and 1.4 mg per 100m1 of the mash respectively, on the use of wheat flour and corn flour. 3. No remarkable differences between the kind of raw materials and commercial amylases and compared with the mash brewed with Nurook were observed in the components of fusel oil formed in the mash. 4. Seventeen kinds of the amino acids of the mash brewed with commercial amylase, Lactobacillus and the yeast were detected and its content was 31mg per 100ml, which is less than that of the conventional takjoo, but the contents of glycine and alanine which pray as the component of seasoning in takjoo were sufficient.

Soluble solids $(^{\circ}Brix)$, acid content and vitamin C content of Citrus miyakawa unshiu and C. okitsu unshiu juice harvested middle of November 1993 in Seuho-Dong and Topyung-Dong, Seogwipo-si, south area of Cheju were $10.7{\sim}11.0$, 1.04% and $41.19{\sim}44.94\;mg/100\;g$ juice, respectively. Carbohydrate was consisted of about 1/2 sucrose, 1/4 glucose, and 1/4 fructose. Fruit weight, peel thickness, soluble solids, pH, acid content and Brix/Acid ratio had a good correlation in linear function with increasing fruit size, respectively. However, hardness and edible part ratio were not showed correlation with increasing fruit size. Middle size of citrus fruit was favorable to panelists, and the citrus peel color of red yellow was more favorable than pale yellow color in sensory evaluation. Sensory evaluation score showed a linear correlation among citrus fruits of C. okitsu unshiu produced in Namwon-ri, Seuho-Dong, Seogwipo-si, south area of Cheju, and that of Chochun-ri, Ara-Dong, Cheju-si, north area of Cheju, and the score was higher according to citrus fruit produced in optimum cultivation area. With increasing Brix/Acid ratio of citrus juice, high sensory evaluation score was gained in panelists. These data obtained are supposed to be applied to the quality evaluation of Citrus unshiu produced in Cheju.
