In this study, succession aspects of direction structure and dancing were reviewed in Moondoong drum dance succeeded by Yong Bae Cho of Goseong Ogwangdae. Sung Rak Hong who succeeded to Moondoong drum dance before Yong Bae Cho directed only 'drum dance' mainly with Goodguri rhythm. While Sung Rak Hong succeeded, the drum of Moondoong Gwangdae became smaller, which was changed from drum before 1965, to semi-drum in 1966 and tabor in 1967 and thereafter. Yong Bae Cho succeeded to Moondoong drum dance since 1970, adding 'Moondoong dance' directing tabor at the floor together with 'drum dance' before August 1972 and directing Dutbaegi rhythm. From the first succession of Goseong Ogwangdae since the winter in 1974, obscene movements were disappeared, and the setting with Yangban and contents to sublimate resentment were added in Moondoong drum dance. These changes seemed to be affected by succession format of Tongyoung Ogwangdae Moondoong drum dance and Ok Jin Gong's idiot dance. There are succession patterns when reviewing Moondoong drum dance directed by Yong Bae Cho. In case of 'Moondoong' dance, repeated forms were succeeded including 'fixed dance'->'impromptu dance'->'jump' in center of three fixed dances. In case of 'drum dance,' repeated forms were succeeded including 'fixed dance'->'rolling tabor'->'concluding' -> 'impromptu dance'->'jump' in center of four fixed dances. In 'drum dance' by Yong Bae Cho, many parts of succeeded dance by Sung Rak Hong who was a prior successor were remained. After Yong Bae Cho's death, Jong Bok Heo summarized the dance with more completed order focusing on the structure of Moondoong drum dance succeeded by Yong Bae Cho. Since then, multiple scenes were added continuously including hobbled appearance by Jong Won Heo, happy scene eating barley and scene to catch tabor stick difficultly, by Chang Ryol Heo. Yong Bae Cho added 'Moondoong dance' to the prior works only with 'drum dance' and started adding the story with resentment. The direction structure summarized by Yong Bae Cho became the basic framework in which the following directors added the scenes very easily. Like this, Yong Bae Cho was an excellent director of Goseong Ogwangdae who inherited Moondoong drum dance from the previous generation to establish and develop to hand over the next generations.

A calculating method of transient temperature distribution due to spot welding of thin plates is studied in this paper. Considering the contact stress between upper and lower plate and temperature-dependence of specific resistance and elastic limit of base metal, the model of calorific density of heat source was decided. Using 2-dimensional polar coordinates system, the governing equation of heat transfer was developed. The thermal cycles of various points were recorded using C-A thermocouples during spot welding procedure for mild steel plates of 1mm thickness, and those results were compared with the results of calculations presented in this paper.

Cyclic delay diversity (CDD) is a simple transmit diversity technique for an OFDM system using multiple transmit antennas. However, the performance of post-FFT estimation, i.e., integer frequency offset (lFO) is deteriorated by high frequency selectivity introduced by CDD. In this paper, the IFO estimation scheme is proposed for OFDM-based DRM+ system with CDD. Based on the pilot subset partitioning, the proposed IFO estimation scheme reduces the effect of performance degradation caused by frequency selectivity in OFDM systems with CDD . The simulation results show that the performance of the proposed IFO estimator is significantly improved when compared to that of the conventional IFO estimator.

In this paper, fatigue testing was carried out under the change of aging time(0.5,1.5.10hrs) by electric heating method which is one of the useful method in the application of Robot's actuator. Fatigue degradation behaviors such as cyclic deformation property, amount of deformation, decrease in recovery and variation of transformation temperature for each specimen were examined closely, and the effect of aging time condition was studied on their fatigue degradation behaviors.

Recently, it is getting more and more important ensuring the integrity for the equipment degradation according to the increase of nuclear power plant operating period. In many equipment of the nuclear power plant, snubbers mainly installed in reactor coolant pumps, steam generators and piping protected the equipment and piping from the occurrence of transient dynamic loads such as the earthquake, thermal load during the plant operation. This report describes the function, regulation, inspection requirements and management status of the snubbers installed in domestic nuclear power plants.

차륜없이 전자석에 의해 부상하고, 리니어모터에 의해 추진하는 시스템이다. HSST의 가장 큰 장점은, 접촉지짖에 의한 저소음 및 공기저항외에는 주행저항이 없기 때문에 고속주행이 가능하다. HSST도 당초에는 최고속도 200∼300km/h 정도의 시스템 HSST-200, HSST-300 타입을 목표로 개발을 진행해왔지만, 최근에는 급구배 및 급곡선 통과가 가능한 특성을 활용하여 도시내 교통을 대상으로 하는 최고속도 100km/h 정도의 시스템 HSST-100 타입 개발에도 주력함으로써 실용화에 달하고 있다. 경량전철로서의 취급하고 있는 시스템은 HSST-100 타입이다.(중략)

Bragg 반사는 입사된 주기파의 진폭이 해저지형의 진폭의 2배가 될 때 파랑의 반사율이 공명현상(resonance)에 의해 매우 커지는 물리적 현상을 말한다. Bragg 반사를 응용할 경우, 외해로부터 입사되는 파랑 에너지의 상당량을 반사시킬 수 있으므로 항만이나 방파제 등의 해안구조물을 경제적으로 설계하고 보호할 수 있다. 또한, 해안선 보호 및 불필요한 침식이나 퇴적 등을 고려한 연안개발계획의 효율적 수립이 가능하다. (중략)
