  • A chronological classification of Sangbok(상복) and Sibok(시복) for officers in Joseon Dynasty is proposed in this paper. The classification results in four distinct periods according to the usage of Sangbok and Sibok as well as their colers and naming: 1) the mixed usage period, 2) the usage-differentiation period, 3) the name-differentiation period, and 4) name-reversal period. During the mixed usage period which lasted until the early 15th century, Sangbok and Sibok were used with no distinction. In the usage-differentiation period, the King Sejong first made a regulation on the use of colors of Dal-lyung according to the occasion and black colored uniforms were used only for daily cabinet meetings. In the 16th century, the names of Sangbok and Sibok began to be used distinctively: Sangbok for formal clothing in black color and Sibok for ordinary clothing in pink color This period is defined as the name-differentiation period in this paper. In the name-reversal period f·hick begun around the 17th century, the usages as well as the colors of Sangbok and Sibok are totally reversed because of some confusions of the understanding on the previous government publications. However, the distinction of formal clothing and ordinary clothing remained.

  • 세계적으로 수소에너지를 미래 에너지의 대안으로 여겨지고 있기 때문에 수소에너지 관련기술은 미래 국가 경쟁력을 좌우할 것으로 예상되고 있으며 수소에너지시대의 핵심인 수소스테이션 관련기술을 개발은 국가 연료전지 시장을 비롯한 수소 자동차 산업 전반에 큰 영향을 미칠 것으로 예상되고 있다. 이에 따라 전 세계적으로 수소에너지를 차세대 에너지원으로 개발하기 위하여 전력을 다하고 있으며 수소제조기술개발 및 수소스테이션 실증연구가 진행되고 있다. 본 연구에서는 수소제조장치 관련 국내외 기술개발 현황과 수소스테이션용 고효율 수소제조장치 장치 개발 현황을 소개하고자 한다.
