  • The purpose of this study is to suggest the introduction plans of forest land bank system for effective forestry management as well as the livelihood stability support of aged forest landowners. It is expected that forest land bank system can contribute to solve forestry management problems caused by small and scattered forest lands, aging forest landowners, and the increase of absentee forest landowners. This study examined an existing related case of Farmland Bank system, and suggested basic directions, main functions, priority, and agency for forest land bank system. The goals of forest land bank system include activating private forest land management, improving forest management scale, and supporting stable forestry income. Based on the examination of this study, main projects of forest land bank involve forest land sale and lease consignment, forest land reverse mortgage, forest land scale improvement project, and forest business recovery support program. In addition, this study discussed potential problems and their solutions in introducing and operating the forest land bank system. This study can play a key role to determine a basic direction and to establish policies of the forest land management.

  • Although various methods have been proposed and utilized for video reality improvement, use of olfaction still remains at a rudimentary stage. Previous research reported reality improvement effect of some scents when a video displayed specific objects whose odors matched to the scents provided. In addition, another study showed that provision of scents that correspond to the prevailing color of a video improves sense of immersion. However, the above studies have clear limitations because not all videos have specific odor or obvious color. Assuming, in this study, that sensibility-based scent provision in the absence of main odor or color will increase sense of reality, the present study aimed at building adjective profiles of various scents that convey different sensibilities. To this end, in Experiments 1 and 2, we collected a set of adjectives appropriate for description of scents, and in Experiment 3, we built profiles of 16 scents using 30 adjectives. In addition, we grouped scents of similar sensibilities using cluster analysis. These results could be used not only for video reality improvement but also for the purposes of emphasizing product concepts or store positioning, etc.

  • School violence that have occurred recently, showing a tendency to collectivization and diverse types of violence, as well as the quality and increase the damage levels. School violence in the home, school, and social factors, but is caused by the lack of awareness about the violence and the reporting of consciousness due to poor acts of violence indirectly assisted. The only place violence has caused the school to establish the legal and institutional arrangements in order to minimize school violence have no choice but to limit its effectiveness is negligible. The problem of school violence in connection with the problem of juvenile crime prevention and control, and punishment should be made of the complex and layered. Operation and School police system, School safety keeper system, school sheriff system since 2005, each municipality in order to minimize school violence, but have no practical help to limit the visible and symbolic effects. Nonexistent professional staff of the institution or school safety monitors emphasis on monitoring the physical state of the system in the form of 'guards' departure inherently have limitations. Also, to prevent criminal acts or violence in the state is not given special privileges and the appropriate role for the school keeper is a problem with the system. Report no other role can not be expected. Should therefore be preceded by a systematic improvement and training of experts in order to prevent school violence, and home and school, in terms of social support and measures.

  • Byeolseo was located in various places with beautiful natural scenery to avoid the mundane world and for country life in seclusion. In this study, to classify locational type and characteristics of Byeolseo in Gyeongsangnamdo and Jeollado areas, complex locational types and characteristics of total 96 Byeolseo (52 in Gyeongsangnamdo and 44 in Jeollado) were researched and cluster analysis was executed to group locational characteristics to several clusters with similar characteristics in order to classify locational types of Byeolseo. As the result, locational type for Gyeongangnam-do and Jeolla-do were classified to 5 types each. Unique locational types Gyeongsangnamdo were 'valley type' and 'cliff type' and unique ones for Jeollado were 'flatland type' and 'riverside.hill type'. 'Hill type', 'curvy river type' and 'riverside other type' were shown in both areas. In Gyeongangnamdo, 30.8% was cliff type and 15.4% was valley type 46.2% of the total was locatedon 'cliff near river' or 'valley'. These were the most popular locational characteristics of Gyeongangnamdo. Unlike Gyeongangnamdo, 18.2% was flatland type, 18.2% is riverside.hill type, and 39.6% was hill type in Jeollado 75.0% of the total was locatedon 'flatland', 'on hill near river' or 'on hils'. These were the most popular locational characteristics of Jeollado. Such locational characteristics showed that Byeolseo was located using nearby scenery considering topographic characteristics of the located area.

  • In the study, the log pricing process by region and marketing agencies was surveyed in order to analyze the domestic timber marketing situation, and to propose improvements. The results obtained show that the market channel configuration for domestic timber is simple compared with that for the agricultural products. The log felling contractor is the lead agency in the stumpage market because of the lack of market information of most forest owners. However, the log assembler, who has ample funds, seized leadership in the market channel because most felling contractors, deal only with small timber quantities, and are usually short of funds. Also the variety of log scaling methods is a serious factor confusing domestic timber marketing. Therefore, the following steps are proposed; 1) the provision of market information to forest owners, 2) the institutional control of felling contractors, 3) the establishment of cooperative log collection centers, 4) the improvement of log quality.

  • The purpose of the paper is to research issues and implications on a large-scale enlargement of urban area in city management plan. This study investigated laws and regulations in force and carried out case study for three cities such as Yangju-si, Gimpo-si, Whaseong-si. As a result of analysis, three points at issue were abstracted and improvement ideas for each of them were suggested as follows. First, to set up adequate size of urban area, it is necessary to consider resonable planning for population, spatial structure, zone of life and land use in city comprehensive plan and city management plan. Second, to decrease arguments about scope and bounds of urban area, it is important to make general and specific guidelines to set up them. Third, to manage new urban area and its surroundings efficiently, it is necessary to subdivide zoning of non-urban area strictly, to restraint individual location of factories or cattle sheds, to make a proper infrastructure plan in advance, to administer strongly the permission of development behavior and to control strictly consecutive and joining development in non-urban area.

  • The phenetic relationships among six natural populations of Equisetum pratense in Korea were investigated at the population level by constructing a tree based on Random Amplified Polymorphic DNA (RAPD) markers. RAPD analysis was also conducted to estimate genetic diversity and the population structure of E. pratense. A mean of 26.7% at the six population levels indicated polymorphism. E. pratense was found to have fewer alleles per locus (1.267) and fewer effective alleles per locus (1.176). Genetic diversity (0.102) in E. pratense is lower than the average for species with similar life history traits. Total genetic diversity values (HT) varied between 0.112 (OPD-07) and 0.445 (OPD-16), for an average overall polymorphic locus of 0.141. Inter-locus variation in the within-population genetic diversity ($H_S$) was low (0.102). Asexual reproduction, small population size, and the colonization process are proposed as possible factors contributing to the observed low genetic diversity in E. pratense. On a per-locus basis, the proportion of total genetic variation due to differences among populations ($G_{ST}$) ranged from 0.129 for OPD-07 to 0.455 for OPD-09, with a mean of 0.277. This indicated that about 27.7% of the total variation was among populations. Thus, genetic variation (72.3%) resided within populations. This study contributes new information for research on the taxonomy and population genetics of E. pratense.

  • Due to growing problems securing stable mineral and energy resources with international political and economic changes, China has dedicated itself to strategies and policies to enhance its stable mineral and energy resources security. China has established a rare earth elements(REE) industry policy after the abolition of the REE exports quota system. China's six large REE companies have also been integrated into REE mining, smelting and refining companies. Efforts have been increased to enhance China's energy security through unconventional oil and gas exploration and development investment, as well as effort in R&D. The country will focus on technology development and exploration to promote commercial production of unconventional oil and gas based on countries with shale gas. China is making long-term contracts and joint ventures to ensure the acquisition of reliable mineral and energy resources from abroad. Government of China has proposed a range of initiatives, such as the integration of resources development strategies and environmental development strategies, internationalization of resource management, supply diversification and advancement, strengthening industry linking strategy, grouping and diversification strategy.
