  • This study investigates the importance of records management for local festivals by focusing on the Chunhyang Festival, one of Korea's oldest regional festival still in existence. This study analyzes the current conditions of records management to indicate problems and offer measures of importance. The results of this study showed the following problems. First, the absence of public-private partnerships and the lack of a stable commission. Second, the absence of ordinances for festival public records management. Third, the absence of systematic document management. Finally, absence of an expert records researcher and the absence of a records archive. Therefore, the study floated for an overall management method for the Chunhyang Festival records.

  • 정부는 2006년 8월 기존의 발전차액 지원제도를 개정하여 발전차액 기준가격 지원대상 확대, 적용기간의 15년 단일화, 수력, 바이오에너지는 고정요금과 변동요금 중에서 선택할 수 있는 선택권 부여, 기술발전에 따라 태양광, 풍력, 연료전지는2-3년간의 유예기간 이후 매년 감소율을 적용하여 기준가격을 낮추는 등 많은 제도개선 내용을 반영하였다. 2006년 10월부터 개정된 발전차액 지원제도가 시행된 이후 태양광, 풍력의 신규진입이 대폭 증가하였고 수력, LFG, 바이오가스는 대부분 변동요금을 신청하였으며 2007년 집행된 신재생에너지 발전차액 기반기금의 55% 이상이 태양광발전에 지급되는 편중현상의 영향이 나타났다. 따라서 변동요금 설계시보다 SMP 평균이 22원 이상 높아져 변동요금의 재설계, 태양광 발전의 기반기금규모가 55% 이상을 점유하고 있으며 향후 더욱 심화될 예정이므로 특정전원의 기반기금 점유비중 제한 및 최근 수년간 준공된 신재생에너지의 운영실적을 분석하고 법적요건을 상세히 검토하여 투자비, 운영비, 이용률등을 재조정하여 기준가격을 합리적으로 개정하여 제2의 신재생에너지 도약기를 마련해야 할 것이다.

  • 도시지역에서 하천제방의 붕괴로 인해 제내지 범람 홍수파가 발생하였을 경우에 적지 않은 인명 및 재산 피해가 발생할 수 있다. 피해를 줄이기 위해서는 제내지 범람 홍수파의 거동특성을 명확히 밝혀낸 후, 제방 붕괴에 의한 홍수범람에 대한 대피 체계를 설립하는 것이 바람직하다. 본 연구는 범람 홍수파가 발생하였을 경우에 제내지에서의 범람 홍수파의 영향을 3차원 수치모형인 Flow-3D를 이용하여 모의하였다. 또한 비교 검토를 위하여 구조물이 없는 평탄지형에 대해서도 수치모의를 수행하였다. 높이 0.6m의 제방이 붕괴되어 붕괴 폭 변화와 제내지의 구조물의 유무에 따른 제내지 범람 홍수파의 속도 및 수심의 변화를 분석 하였다. 모의 결과 제방 붕괴 시 붕괴 폭의 변화에 따른 홍수파 전파속도는 별 차이가 없는 걸로 나타났다. 수심의 변화는 제방붕괴지점으로부터 멀어질수록 낮아졌고, 수심 변화폭도 일정하게 유지되었다. 또한 구조물이 있는 경우가 그렇지 않는 경우에 비해 제방 붕괴부 주위에서의 수심은 증가하는 것으로 나타났다. 본 연구결과를 비롯한 수치모의결과를 적절하게 활용하게 되면 제방붕괴에 의한 홍수범람에 대한 대피체계(EAP)를 수립하는데 기초 자료로 활용될 수 있을 것으로 사료된다.

  • A comprehensive understanding is given for the hot-firing test results, which were obtained throughout the verification program of mono-propellant hydrazine rocket engines (thrusters) producing 0.95 lbf (4.2 N) of nominal steady-state thrust at an inlet pressure of 350 psia (2.41 Mpa). A scrutiny for the engine performance is made in terms of thrust and temperature behavior of steady state firing mode at the given propellant injection pressures: Pinj = 400, 250, 100, and 50 psi. The thrust and specific impulse are compared with a reference performance of 1-lbf standard rocket engines and their normalization procedure is introduced. A practical engineering approach to the data measurement and reduction is addressed, too.

  • When comparing the port management type between the both countries, there are some differences at some aspects. And also Korea is to move forward a hub port and logistics center in Northeast Asia while Japan is to pursue providing the port logistics service necessary for the Japanese economy. Major findings and implications are as follows. first, Port authority system should be extended to Gwangyang and Pyeongtaek port step by step. Second, any port which did not introducing a port authority system should enhance cooperating with its own local administration. Third, a port marketing strategy must be established and implemented by a port authority.

  • In this study, we analyze the characteristic of burning classified by a propellant according to a flux of an oxidizer to analyze propellant regression distance in accordance with a thrust control and burning time of hybrid rocket using hybrid combustor of Lab-Scale. To control a flux of an oxidizer, we design flow control system to regulate the mount of opening and shutting of a needle valve by a driving of stepping motor by a combination the needle valve with stepping motor. We derive the relationships between mass flow rate and regression rate according to a propellant through the oxidizer flux change. While doing the thrust control, we estimate regression distance through the oxidizer flux in accordance with thrust and confirm the creditability through the actual thrust control burning experimentation.

  • Extinguishment of a burning solid propellant is difficult, however, dynamic extinction can be induced by fast depressurization in combustion chamber. This paper describes experimental results for the characteristics of extinguishment for composite solid propellants by rapid depressurization. For various composition of solid propellants, depressurization ratio which can induce extinguishment of combustion was obtained using experimental apparatus with rupture disk. Experimental results showed that particle size of oxidizer, mixing ratio of oxidizers with different particle size and contents of metal fuel can affect on the characteristics extinguishement for solid propellant.

  • The 3-dimensional GIS data provider system manages and retrieves 2, 3-dimensional spatial and time data. This system provides the standard interfaces which help developers to omit additional works to do modify or convert a format of 2 or 3-dimensional spatial data, which has been already accumulated, into that dependent on a specified system. This system consists of a data provider and data access component. The former deals with the connections with some databases and manages the meta data, so that the various GIS or software can access to 3-dimensional spatial and time data via the same method, and the latter takes charge of index management and spatial operations on GIS data for consumers. The system offers the diverse spatial operations and analysis functions for 3-dimensional GIS.

  • Differential scanning calorimetry and numerical analysis were performed to estimate the performance degradation and ignition characteristics of the pyrotechnic device due to aging. The reaction kinetics extracted from the calorimetry are implemented into the numerical simulation of the igniter and the pyrotechnic delay, subjected to natural, thermal, and hygrothermal aging conditions. Also, combustion experiments are conducted to confirm that aging due to moisture is a major cause of performance failure of the pyrotechnic device as shown from the present numerical simulations.

  • Marine pollution prevention manager system has been operated for the purpose of preventing marine pollution from ships and marine facilities in Korea. As a new "marine environment management act" replacing an old "marine pollution prevention low" had entered into force from January 20, 2008, the education system for marine pollution prevention manager is to change in some ways. Major changes in education/training institutions, education/training courses, trainees, marine pollution prevention manager's works and business, marine facilities and educational subjects are summarized, comparing between old "marine pollution prevention act" and new "marine environment management act".
