Injection-stretch blowing system for preform has been developed in this study. The preforms for injection blow molding and injection stretch blow molding are being manufactured by injection molding. However it contains gate mark that affects the bottom crack in the PET bottle. The compression molded preform does not contain gate mark, thus the appearance quality of bottle has been increased and the residual stress near gate(bottom of the bottle) has been reduced. The thickness distributions, haze, and transmittance are well accepted for the preform. Also, flow characteristics of the resin between a core and cavity could be analyzed through computer simulation.

Physical Media Dependent Prototype for 10-Gigabit-Capable PON OLT

김종덕,이종진,이세형,김영선 한국전자통신연구원 2013 ETRI Journal Vol.35 No.2

In this work, we study the physical layer solutions for 10-gigabit-capable passive optical networks (PONs), particularly for an optical link terminal (OLT) including a 10-Gbit/s electroabsorption modulated laser (EML) and a 2.5-Gbit/s burst mode receiver (BM-Rx) in a novel bidirectional optical subassembly (BOSA). As unique features, a bidirectional mini-flat package and a 9-pin TO package are developed for a 10-gigabit-capable PON OLT BOSA composed of a 1,577-nm EML and a 1,270-nm avalanche photodiode BM-Rx, including a single-chip burst mode integrated circuit that is integrated with a transimpedance and limiting amplifier. In the developed prototype, the 10-Gbit/s transmitter and 2.5-Gbit/s receiver characteristics are evaluated and compared with the physical media dependent (PMD) specifications in ITU-T G.987.2 for XG-PON1. By conducting the 10-Gbit/s downstream and 2.5-Gbit/s upstream transmission experiments, we verify that the developed 10-gigabitcapable PON PMD prototype can operate for extended network coverage of up to a 40-km fiber reach.

침자극이 흰쥐 뇌줄기 및 소뇌의 NADPH-diaphorase와 nNOS 신경세포에 미치는 영향

김종덕,강성길,김창환,Kim, Jong-deog,Kang, Sung-keel,Kim, Chang-whan 대한침구의학회 2004 대한침구의학회지 Vol.21 No.5

Objective : This study was to investigate the effect of acupuncture on NADPH-diaphorase and nNOS in the brain stem and cerebellum of spontaneously hypertensive rats. Methods : The experimental groups were divided into four groups : Normal, Choksamni(ST36), Kokchi(LI11), arbitrary group. Thereafter we evaluated changes in NADPH-diaphorase positive neurons histochemically and changes in nNOS neurons immunohistochemically. Results : 1. The optical densities of NADPH-diaphorase positive neurons of all the Choksamni & Kokchi groups were significantly different in SuG, DLPAG, IP, Pr, Gi areas of brain stem and cerebellum as compared to normal & arbitrary groups. In PPTg only Choksamni group was significantly different as compared to normal and arbitrary groups. 2. The optical densities of nNOS-positive neurons of Choksamni & Kokchi groups were significantly different in SuG, DLPAG areas of brain stem as compared to normal group. In IP, Pr only Kokchi group was significantly different as compared to normal group. The optical densities of nNOS-positive neurons of Choksamni & Kokchi groups were significantly different in SuG, DLPAG, PPTg, Pr, Gi areas of brain stem as compared to arbitrary group. In IP, Pr only Kokchi group was significantly different as compared to arbitrary group. 3. The optical densities of nNOS-positive neurons of all the Choksamni & Kokchi groups were not significantly different in cerebellum as compared to normal & arbitrary groups. Conclusions : We found out that acupuncture have effects on NADPH-diaphorase and nNOS in the brain stem and cerebellum of spontaneously hypertensive rats.

DWDM 송신을 위한 파장안정화 고출력 DFB LD Module

김종덕,이희태,박경현,송만규,강승구 한국광학회 2000 한국광학회지 Vol.11 No.3

A wavelength stabilized high power CW DFB LD module was designed and fabricated for use in externally modulated, Dense Wavelength Division Multiplex (DWDM) systems. A simple, compact wavelength monitoring technology using a thin solid Etalon and PD array assembly was developed for a low cost wavelength stabilized DFB LD module. Also, the excellent module have high power characteristic of 13.5 mW in CW 100 mA current injection with high optical coupling coefficient over 43%. r 43%.

최근 세계적인 조선 시장의 침체기에도 불구하고, 선박 시스템 원천기술 확보의 중요성이 지속적으로 부각되어 오면서, 세계적으로 선박 시스템 원천기술 확보를 위한 다양한 노력들이 진행되고 있다. 이에 본 논문에서는 선박추진제어 시스템의 국산화를 통해 해당 분야의 원천기술을 확보하고자 추진제어시스템의 원격운용장치의 구현에 대하여 연구하도록 한다. Although recent years whole of shipbuilding market is seriously stagnant, an importance of ship fundamental technology issues has been increased. Accordingly diversity attempts to get various solutions are in progress by national support. Therefore, in this paper it deals with a remote operation control system which is a part of propulsion thruster system. it is proposed a propulsion thruster remote operation control system which is developed by localization technology as well as the methods not only to design hardware and software but to develop hardware and software.

헤이즐넛 첨가에 따른 청국장의 품질 특성 변화

This research was conducted to investigate the changes in quality characteristics of cheonggukjang fermented with the addition of hazelnut (10, 20, 30 and 40%) including; water content, pH, hydrophilic and lipophilic substances, color, viscosity and angiotensin converting enzyme inhibition activity. There was no significant change in pH with the addition of hazelnut. The water content significantly decreased with the addition of hazelnut. Hazelnut was also found to brighten the color of cheonggukjang. L-value and b-value increased with the addition of cheonggjuang. There was an insignificant change in the a-value. There was a slight decrease in the content of hydrophilic with addition of hazelnuts. Where there was more than 20% addition of hazelnut to soybean, the viscous substance content in cheonggukjang decreased significantly. Angiotensin converting enzyme inhibitory activity increased proportionally to the amount of hazelnut added. It was identified that the addition of 40% of hazelnut made its angiotensin converting enzyme inhibitory activity 10% point higher than that of control. These results suggests that the addition of hazelnut makes it possible to produce cheongkukjang of excellent angiotensin converting enzyme inhibitory activity.

도로위험정보알림 디바이스 구현

김종덕,한승헌,김영길 한국정보통신학회 2019 한국정보통신학회논문지 Vol.23 No.4

차량의 보급 증가와 함께 신규 도로 건설 및 기존 도로의 확장이 늘어나고 있으며, 이와 함께 도로 위 다양한 위험들은 비례적으로 증가하고 있다. 이러한 위험들은 크게 고정위험과 가변위험들로 나타나고 있으며, 현재는 네비게이션을 통해 과속, 사고다발, 낙석주의 등에 대한 고정위험이 운전자에게 안내되고 있다. 그러나 도로위험정보는 고정위험정보보다 가변위험정보가 그 위험성이 높다 할 수 있는데, 가변위험 정보의 경우 맵 회사들이 수기로 정보를 입력하고 있는데, 이는 실시간성이 떨어지며, 돌발 위험에 대한 대응이 되지 않는다. 이에 본 논문에서는 이러한 문제점을 해결하고 실시간 위험정보를 운전자에게 안내하여 공공이익에 기여할 수 있는 도로위험정보알림 장치에 대해 제안하고 구현하여 도로 위 위험정보의 활용에 대한 방향성을 제시한다. With the increasing supply of vehicles, construction of new roads and expansion of existing roads are growing and this is leading to a proportional rise in diverse hazards on a road. These hazards are classified into fixed hazards and variable hazards. Currently, drivers receive information of fixed hazards, such as overspeed, frequent accidents, and rock fall through navigations. However, variable hazards are more hazardous than fixed hazards. Map companies frequently enter information of variable hazards manually, but it is less real-time and hard to deal with unforseen hazards. This paper is intended to implement a road hazard warning system for making a contribution to pubic interests by improving this problem and delivering real-time information of hazards to drivers, and suggest a direction for using information of hazards on a road.
