우스키 마애불상군의 모암은 아소-4 화산쇄설암층군에 속하는 암회색 응회암이다. 이 불상군은 상부에서 유입되는 강수와 지반에서 상승하는 지하수로 인한 백화현상과 암반의 토양화가 상당히 진행되어 보존대책이 시급한 상태였다. 불상군 표면 염풍화의 주요 원인인 백색오염물에서는 세나다이트, 석고, 백운석이 동정되었다. 이들의 용출실험 결과, 세나다이트는 교반초기에 용해되었다가 4시간 이후 재용출되고, 석고는 2시간 교반까지 검출되다가 4시간 교반 후 용해되는 특성을 보였다. 백색오염물의 재결정 환경을 파악하기 위해 11개월간 미기후 환경을 모니터링한 결과, 봄철에는 세나다이트와 미라빌라이트의 상전이가 넓게 나타나고, 여름과 가을철에는 고온으로 인해 수용액 상태로 유지된다. 겨울철에는 온도가 하강하면서 미라빌라이트의 분포대가 가장 넓게 도시된다. 따라서 석불군 일대의 수분 이동통로를 차단하고 보호각 내에서 유지되는 다습한 환경을 제어하기 위한 초정밀 관측이 요구된다. The host rock of the Usuki Stone Buddha Statues is dark gray welded tuff involved the Aso-4 pyroclastic flow sediments. This Buddha Statues are processing chlorosis from rainfall flowing above and underground water which were urgently needed for conservation measurement. White precipitates, the main source of salt weathering, on the surface of the Buddha Statues are mainly consisted of thenardite, gypsum and dolomite. Extraction experiment result shows that thenardite was dissolved at the beginning of stirring and then redissolved after 4 hours, and gypsum was detected until stirring for 2 hours, and then dissolved after stirring for 4 hours. As a result of monitoring the microclimate environment for 11 months to determine the recrystallization environment of white precipitates, the phase transition between thenadite and mirabilite appears widely in spring, and is maintained in an aqueous solution due to high temperatures in summer and fall. In winter, mirabilite is shown the widest by decreasing temperature. Therefore we requires details monitoring for blocking water transfer port and solved humidity environment in shelter.

A landscape is a complex organic body composed of not only complex elements as visual environment, sound environment, heat environment and air environment, but also the perception and activities of humans living within. As such, for complex organic landscape which cannot be defined by any one element alone, there are needs to investigate new methods of mutually organic planning through defining the correlation between various pertaining elements. Therefore, this study attempted to realize a comprehensive understanding and plan by dealing with perception experiment analysis of cognition as well as physical analysis through literature research and site surveys to investigate the correlation between colorscape and soundscape in the landscape. Site color, cognitive color, harmonious color, and field sound, cognitive sound, and harmonious sound in each landscape showed almost similar natural green landscape, waterside landscape, and urban landscape, and the analysis of spatial images through adjective vocabulary of each image was also evaluated as similar. Natural green landscapes were almost similar in the evaluation of cognitive color, harmonious color, harmonious sound, and adjective vocabulary, but car sounds did not match and caused discomfort, indicating that colors and sounds that match each type of landscape exist and need to be managed. By type of landscape, urban landscape > waterside landscape > natural green landscape was recognized as strong and high sounds, and compared to colorless images, colored images were evaluated as strong and high sounds regardless of landscape type.

If the directors violated their duties and that resulted in the damages of such corporations, director should compensate for those damages. In principle, the corporation preserves the right to demand compensation against the directors who caused the damages. But if the corporation doesn’t claim against the concerned directors, the minority shareholders could do it for the corporation. Under the German Stock Corportion Act, the corporation’s creditor also could bring a suit for the corporation. If the creditor could not obtain satisfaction from the corporation, the corporation’s creditor can make a claim for the corporation in their own name and up to the amount of their claims against the directors who are subject to the indemnifications. But the directors who are subject to the indemnifications could compensate those damages not only to the corporation but also to its creditor, by which they are relieved from the obligations. The creditors doesn’t preserve any priorities over the corporation and its creditors. If insolvency proceeding were initiated over the corporation’s property, the creditor cannot make any more claims for the corporation. Therefore, creditor’s right to resort the corporation’s claim is meaningful only when the filing for initiating insolvency proceeding is rejected.

Wenn der Aktiengesellschaft durch Pflichtverstoßen der Verwaltungsorgane ein Schaden entstanden ist, sind die Organmitglieder der Gesellschaft zum Ersatz verpflichtet. Grundsatzlich hat die Gesellschaft selbst die Befugnis, ihre ErsatzansprUche gegen die Pflichten verletzten Organmitglieder geltend zu machen. Wenn die zustandigen Organe der Gesellschaft aber aus Solidaritat oder aus Furcht vor Aufdeckung eigener Versaumnisse ihre ErsatzansprUche nicht ausUben, konnen die Minderheitsaktionare fUr ihre Gesellschaft die Klage erheben. Das deutsche Aktienrecht enthielt nur Regelungen Uber die Klageerzwingung, nach denen Minderheitsaktionare die Gesellschaft zur Geltendmachung von ErsatzansprUchen verpflichten konnten. Seit dem Inkrafttreten des UMAG vom Jahr 2005 sind den Minderheitsaktionaren das Recht, die Aktionarsklage zu erheben, gewahrt worden. Beschließt die Hauptversammlung mit einfacher Stimmenmehrheit die Geltendmachung der ErsatzansprUche, ist die Gesellschaft dazu verpflichtet. Der Begriff der Geltendmachung umfasst sowohl die Durchsetzung auf gerichtlichem, als auch auf außergerichtlichem Wege. Man benutzt aber in der Regel einen Ausdruck von Klageerzwingung, weil die gerichtliche Geltendmachung gewohnlich ist. Die Hauptversammlung kann die Geltendmachung der ErsatzansprUche auf besonderen Vertreter Ubertragen. DarUber hinaus konnen die Minderheitsaktionare beim Gericht auf Bestellung eines besonderen Vertreters antragen. Aber die Klageerzwingung ist kein vollstandiges System, weil ein Mehrheitsaktionar den Beschluss verhindern kann. Deswegen ist die ein Zulassung des Gerichtes voraussetzende Aktionarsklage eingefUhrt. Aktionare, deren Anteile zusammen den ein- hundertsten Teil des Grundkapitals oder einen anteiligen Betrag von 100.000 Euro erreichen, konnen die Klagezulassung beantragen. Die Voraussetzungen der Klagezulassung sind 1) Vorbesitz der Aktien, 2) Vergebliche Aufforderung zur Klageerhebung, 3) Verdacht der Schadensverursachung durch rechtswidrige oder unredliche Verhalten, 4) Keine Uberwiegenden GrUnde des Gesellschaftswohls. Die Klage ist nur dann zuzulassen, wenn die Voraussetzungen kumulativ vorliegen. Hat das Gericht die Klage zugelassen, kann jeder antragstellende Aktionar die Aktionarsklage erheben. Die Klage richtet auf Leistung an die Gesellschaft. Das deutsche Aktienrecht hat nur die einfache reprasentative Aktionarsklage eingefUhrt, Uber die mehrfache reprasentative Aktionarsklage gibt es keine Diskussion. Denn sind die Minderheitsaktionare und Glaubiger der abhangigen und herrschenden Gesellschaft durch Konzernrecht und Judikaturrecht genUglich beschUtzt. In der letzten Zeit ist im unseren Land die EinfUhrung der mehrfachen reprasentatven Aktionaraklage befUrwortende Meinung herrschend. Aber sind der Minderheitenschutz und die Verantwortung von herrschenden Aktionaren und Verwaltungsorganen der herrschenden Gesellschaft zuerst zu berUcksichtigen. Man muss Durchgriffshaftung, Aktionarsklage und die Haftung von tatsachlichen Vorstanden zur nUtzlichen Anwendung bringen. Außerdem ist die EinfUhrung der Konzernregelungen positiv in Betracht zu ziehen.

In this study, an artificial solar simulator composed of a 2.5 kW Xe-Arc lamp and mirror reflector was used to carry out the solar thermal two step thermochemical water decomposition cycle which can produce high efficiency continuous hydrogen production. Through various operating conditions, the change of hydrogen production due to the possibility of a dual-zone reactor and heat recovery were experimentally analyzed. Based on the reaction temperature of Thermal-Reduction step and Water-Decomposition step at 1,400°C and 1,000°C respectively, the hydrogen production decreased by 23.2% under the power off condition, and as a result of experiments using heat recovery technology, the hydrogen production increased by 33.8%. Therefore, when a thermochemical two-step water decomposition cycle is conducted using a dual-zone reactor with heat recovery, it is expected that the cycle can be operated twice over a certain period of time and the hydrogen production amount is increased by at least 53.5% compared to a single reactor.

업무집행관여자의 책임에 관한 독일 주식법과 상법의 비교연구

In Commercial Code of each country is specified the liability of the person, has affected the company actually with the power like directors, despite he is not a director. The Korean Commercial Code Art. 401.2 has been instituted in reference to the German Stock Corporation Act Art. 117. But both make a little difference. The Korean Commercial Code Art. 401.2 regulate widely the liability of the shadow directors, including de facto directors. In contrast the German Stock Corporation Act Art. 117 regulate only the liability of the person, with influence on the company has instigated the director an act, cause damage to the company. Consequently in German law the liability of de facto directors is resolved not by the Art. 117 but by the Art. 93. Therefore legal entity can not be a de facto directors. Legal entity is responsible by the company law relating to group (konzern law). The German Stock Corporation Act Art. 117 doesn``t regulate the liability of the shadow directors to a third party. So this liability in German law shall be resolved by the civil tort liability. In contrast the Korean Commercial Code regulate the liability for damage of the directors to a third party.
