  • The effects of temperature stress and paraquat on the superoxide dismutase (SOD) activity and the photochemical efficiency of photosystem II were studied in the leaves of Araliaceae plants. The SOD activity of Acanthopanax koreanum leaf discs increased at 4$^{\circ}C$ and 28$^{\circ}C$, and increased significantly at 4$^{\circ}C$ ,28$^{\circ}C$ and 35$^{\circ}C$ in the presence of paraquat. However, the SOD activity of Dendropanax morbifera leaf discs decreased at 4$^{\circ}C$, 28$^{\circ}C$ and 35$^{\circ}C$ regardless of paraquat treatment. The photochemical efficiency of photosystem II, Fv/Fm, of leaf discs of A. koreanum and D. morbifera fell remarkably at 35$^{\circ}C$. In the presence of paraquat, the Ev/Fm values fell slightly at 4$^{\circ}C$ in A. koreanum leaf discs and at 35$^{\circ}C$, in D. morbifera leaf discs. These results indicate that A. koreanum plants are more resistant to temperature stress or oxidative stress than D. morbifera plants although their photochemical efficiency falls slightly at 4$^{\circ}C$ in the presence of paraquat.

  • The purpose of this research was to review the music choices of GIM therapists in GIM. Seven databases and nine music therapy journals were searched with keywords such as "Guided Imagery and Music", "GIM", "Helen Bonny", "Bonny method", "Music and Imagery" and "BMGIM" between 1964 to 2013. Every abstract was confirmed to see whether it meets this research topic. 12 of 126 articles that described the reasons for music choices were selected. It is the result of narrative literature review that GIM therapists chose music to match clients' qualities of moods, emotions, feelings related with issues and clients' themes in therapy. In 5 articles among the 12 articles, authors chose music with considering music elements analytically to match clients' states. Reasonable explanations for music choice were reviewed in these 5 articles. There were limitations to obtain common facts between articles because most of 126 articles were case studies which described from therapists's point of view in a qualitative way. A more fundamental research is required to obtain rationales of music choices in GIM as a music-centered music psychotherapy for the further research.

  • The ISO issued the first standard for environmental management standard(EMS) in 1993. This standard provide for elements of an effective environmental management system and can also help companies ingrain effective environmental management practice into their overall business operations. ISO 14001 is predicted to become the leading voluntary environmental management system standard. Companies selling products and services internationally and domestically will also be affected by publication of this standard. Especially, this new environmental management standards are fast becoming a condition for doing global business because it can be acted with trade barriers. Actually, an automobile companies of America including Ford and GM require their subcontracting companies to gain the recognition of ISO 14001. The purpose of this paper is to investigate the ISO 14000 and its application of Korean firms focusing on environmental management system(EMS). This paper proceeds to present the effective alternatives through analysing the existing Korean firms which has established EMS. Korean firms should adopt EMS not for the enhancement of corporate image but for the purpose of strategic competitive advantage.

  • This study investigates how Abies holophylla was planted as a tree sacred to the gods by Japan during the late Chosun and Japanese colonial periods. This study surveyed the current conditions of old Abies holophylla geological information, year planted, and the relationship between Abies holophylla and traditional Japanese values. The reasons that Abies holophylla was considered a tree sacred to the gods are as follows. Firstly, trees are planted on the spaces between Iljumun and Numun in Buddhist temples of Korea in the same way as trees are planted on the roads for worship in traditional temples of Japan. Secondly, tree diameter at breast height ranged from 60cm to 100cm. This means that the Abies holophylla trees range in age from 70 years to 138 years, showing that the trees were planted at the period between the beginning of Japanese Buddhism(1877) and the Japanese Colonial Period (1945). Thirdly, conclusions regarding why the Abies holophylla were planted in Korean temples at the beginning of Japanese Buddhism will be drawn based on the records that Jingu-Kogo's Conquest of Silla was taken care of the Suwataisha as a tree sacred to the gods in Japanese tradition. The reason for which Abies holophylla was planted in Korean temples should be evaluated through the remnants of Japan in the past. The issue of the old Abies holophylla in Korean temples should be investigated and further discussed in depth.

  • This study focus on the restoration stone selection of break-out part based on material characteristics analysis and the conservational safety diagnosis using various nondestructive techniques for Jungdong and Banjukdong Stone Auariums. As a result, the original rocks of the stone aquariums body are porphyritic granodiorite with magnetite-series having igneous lineation, microcline phenocryst, veinlet and basic xenolith. As a result of the provenance presumption of the host rock, a rock around Gamgokri area in Nonsan City was identified the genetically same rock. Therefore, the rock is appropriate for restoration materials of the break-out part. The deterioration assessment showed that the stone aquariums were highly serious scaling, scale off and blackening. Particularly, the front face of Banjukdong stone aquarium needs reinforcement of structural crack (760mm) caused from igneous lineation of biotite. Blackening contaminants on the stone aquariums surface occurred by combining iron oxide, manganese oxide and clay mineral. Also, major factors of efflorescence contaminants were identified as calcite (Jungdong stone aquariums) and gypsum (Banjukdong stone aquariums). The physical characteristics of stone aquariums appeared that the original and new stone is third (moderately weathered) and second grade (slightly weathered), respectively. This study sets up an integrated conservation system from material analysis to restoration stone selection and conservational safety diagnosis of Jungdong and Banjukdong stone aquariums.

  • This study aims to examine the evolutionary process of the protection-management system for historic monuments and their surroundings in France over one-hundred years. Because France and Korea shared policies and institutions regarding the management of historical monuments (cultural property) along with their surroundings, it is necessary to explore the French experience from a comparative perspective. In France, historical monuments began to be recognized as national heritage according to "the 1913 law" which has continued to evolve for more than one hundred years. In the beginning, a historical monument was preserved as a single building unit; however, since 1943, a new policy has been implemented to preserve sets of historical monuments along with their perimeters of protection zones. Moreover, since 1980, in the context of decentralization, local authorities have been given more roles and autonomy concerning the management of historic monuments and their surroundings. Local authorities have played a key role in the protection-management of historic monuments and their surroundings, and have become more active in the conservation of their architectural heritage, including historic monuments. The central government, however, remains as the headquarters whose rigorous policies provide a solid foundation for the decentralized management system of architectural and cultural heritage, including historic monuments. The final goal in the evolutionary process, then, targets the effective and harmonious integration of the protection-management system for historic monuments and their surroundings into urban and regional planning.

  • This study reviewed important elements that should be considered in developing natural disaster plan in libraries and archives. In Korea, research on natural disaster planning in libraries and archives was rarely conducted. Therefore, it was necessary to study and analyse overseas literature for natural disaster preparedness planning. The key elements for establishing a natural disaster preparedness plan commonly identified in overseas research can be divided into six factors. 'The disaster preparedness committee and roles of staff' should be designated for starting disaster preparedness, and 'Risks' vulnerable to disaster should be assessed and managed in advance. A 'Handbook for immediate response' should be produced for all employees to respond promptly in the event of disaster, and 'Recovery and business continuity plan' should be reviewed for strategic recovery based on disaster scale and return to work after disaster. Also, in order to strengthen the capacity of all staff related to disaster preparedness and to improve plan for disaster, 'Training' is needed, and 'Cooperation activities' between related organisations should be taken into consideration in order to obtain various perspectives for disaster preparedness and to cope with and recover from large-scale disasters. This study can help Korean libraries and archives to establish natural disaster preparedness plan for serious natural disaster that can likely occur in the future.
