Among the figures who were incorporated into the center of power during the reign of Shindon(辛旽), Lee In-im(李仁任) and Lim Bak(林樸) have intermediate characteristics, not typical of a specific political group. Considering those who were still alive even after the loss of Shindon, the actual role and status of Shindon in the political world may have been more limited than those raised in previous studies depicting Shindon as a reformer. During his reign, Shindon, as an agent of King Gong-min, only played a role in removing forces that did not meet the will of the king or threatened the royal authority. King Gong-min led new reforms by sharing appropriate roles and tasks with new aides. In the end, the assumption of Shindon individual as the subject of reform during the reign and emphasizing his reform tendency stems from the error of assuming all the achievements during the reign of Shindon under the leadership of Shindon.

The Zr-based Laves phase, ZrV₂ hydrogen storage alloy is not suited for the electrode of Ni-MH battery, because the binding strength of that with hydrogen is too strong although the storage capacity is high. For an application to electrode a part of V in alloys is substituted with Ni to make weaken the binding strength. The electrochemical and thermodynamic properties of Zr-V-Ni system alloys are investigated from the equilibrium potential and studied the possibility for the application to the rechargeable battery electrode.

New type of metal hydride heat pump (MHHP) combined with hydrogen compressor was constructed for cooling purpose. A model for calculating the coefficient of performance (COP) is presented for MHHP which consisted of two different stages (enforced and natural stage), and compared with the experimental results. A concept of adiabatic compression work is introduced in the model on the basis of Carnot reversible analysis and the dependence of COP on the various operational parameters is discussed.

The operational characteristics of a metal hydride heat pump system are strongly dependent on the amound of hydrogen gas transferred by hydriding and dehydriding reactions between the reactors under dynamic conditions. A new metal hydride heat pump combined with hydrogen compressor was constructed and the dependency of its operating conditions on such as cycle time, amount of hydrogen to be transferred between two reacting metal hydride reactors, operating temperature, and heat transmission characteristics of the reactors was investigated to find the optimum operating efficiency. These conditions were also evaluated in connection with the cooling output and hydrogen compressor connected to the system in order to enhance the total efficiency.

Activation behavior, hydriding rate and disintegration were studied for a compact in pellet form and hydrogen storage alloy particles treated with newly developed inorganic solution. Cylindrical disc of 12.95mm diameter and of 7.1mm thickness was prepared by compressing(8ton) a mixture of MmNi_4.5Al_0.47 and PTFE. Chemical treatment of particles with 1mol of solution was performed at room temperature for several hours until the pH of solution did not change. Chemical treatment made much accelerated activation without any incubation period which generally exists in the untreated alloys and the hydriding reaction rate after full activation also was improved.

Metal hydride used as hydrogen storage material usually needs the activating process to store the hydrogen at high temperature or high pressure. In general as the particle size of metal hydride becomes smaller, approached to the micro, furthermore, nano scale, storage ability and reaction kinetics are reported to be increased, because the specific surface is extremely increased. But the experimental results demonstrated that the optimum particle size is existed for the best absorbing performance, opposite to the usual expectation. This results from the particles to be come amorphous with their approaching to micro and nano scale, in the storage site within the metal hydride lattice is decreased, which is proved by XRD and SEM.

행위주체로서 역사교사들의 교육과정 인식

박찬교(Park, Chan Kyo) 한국역사교육학회 2021 역사교육연구 Vol.- No.40

이 글은 행위주체성이 비교적 잘 드러나는 역사교사들, 즉 ‘연구자로서의 교사’들이 교육과정의 ‘본질’에 대해서 어떻게 인식하고 있는가에 관한 것이다. 구체적인 분석은 연구자로서의 교사를 ‘연구자-실천가’와 ‘반성적 실천가’로 나누어 진행하였다. 구분의 기준은 ① 실천·관점의 공표 여부, ② 학계와의 관계이다. 연구자-실천가 그룹은 교수요목에 가까운 국가 교육과정을 주변화시키고, 교육과정의 중심에 ‘자신’을 위치시키며, 교사를 교육과정 생성의 주체로 보고 있다. 반성적 실천가 그룹은 연구자-실천가 그룹과 유사한 양상을 나타냈다. 연구 참여자들은 국가 교육과정의 구속에서 벗어나고 싶어 했으며, 국가 교육과정은 역사학의 연구 성과가 아닌 역사학의 ‘특성’을 담아내야 한다고 생각했다. 또한 연구 참여자들은 자신의 교육과정이 자의적이거나 편향적이지는 않은지 항상 경계하고 있었으며, 다양한 외부의 압력에 저항하거나 타협하며 교육과정을 변화시켜 나가고 있었다. 역사교사들의 자율적인 교육과정 편성은 점점 더 확산되어 갈 것이며, 이제는 역사교육 분야에서도 국가 교육과정에 대한 관점을 달리해야 한다. 국가 교육과정은 규칙이나 걸림돌이 아닌, 교사의 교육과정 개발·운영을 도와주는 조력자여야 한다. 역사교사가 국가 교육과정 리터러시를 갖추어야 하는 것이 아니라, 국가 교육과정이 역사교사 리터러시를 담아야 한다. 이를 위해서는 다양성이 경합할 수 있도록, 국가 교육과정 공개 공모제를 시행해야 한다. 또한 국가 교육과정은 최소한의 규정과 풍부한 안내로 구성되어야 한다. 이러한 개발 방법을 구현할 수 있다면, 국가 교육과정은 역사교사들의 자율성을 저해하지 않으면서도 역사교육 현장의 중요한 준거로 기능할 수 있을 것이다. This article is about how teachers as researcher with strong agency perceive the essence of the curriculum. Specific analysis was conducted by dividing teachers as researcher into scholar-practitioner and reflective practitioners. The scholar-practice group marginalizes the national curriculum and places themselves at the center of the curriculum. The reflective practitioner group showed similar aspects to the researcher-practice group. They wanted to escape the restriction of the national curriculum, and thought that the national curriculum should contain the nature of history, not the achievements of historiography. In addition, They were always wary of whether their curriculum was arbitrary or biased, resisting or compromising various external pressures and changing the curriculum. The autonomous curriculum construction of history teachers will be increasingly widespread, and now the national curriculum must be different in the field of history education. National curriculum shall be assistants in the development and operation of teacher curriculum, not rules or obstacles. Rather than history teachers should have a national curriculum literacy, a national curriculum should have a history teacher literacy. To this end, a public contest for the national curriculum should be implemented so that diversity can compete. In addition, the national curriculum should consist of minimal regulations and rich guidance. If these development methods could be implemented, the national curriculum could function as an important basis for history education without infringing the autonomy of history teachers.

수소저장합금의 전기화학 및 열역학적 특성에 관한 연구

박찬교(Chan Kyo Park),조태환(Tae Hwan Cho) 한국수소및신에너지학회 1994 한국수소 및 신에너지학회논문집 Vol.5 No.2

Electrochemical and thermodynamic properties of MmNi₅ and the related alloys for nickel-metal hydride battery(Ni-MH) were studied in terms of the equilibrium hydrogen pressure. MmNi₅ alloy with high equilibrium hydrogen pressure(10-20atm at room temperature), which is usually difficult to charge, was substituted for Al in part. Partial substitution of Al made not only the equilibrium pressure to be reduced remarkably, but also the enthalpy change depending on the formation of metal hydride to be agreed to the value in gas phase reaction and electrochemical reaction. Besides the composition of Al which can be given the maximum discharge capacity was turned out to be between the 0.5-1.0 atoms of Al.
