뉴질랜드 남섬 서부에 위치한 알파인 단층(Alpine fault)은 뉴질랜드 남부 호주판과 태평양판의 육상 경계를 일부 형성하는 단층으로, 이 단층에 대한 기존 연구들은 알파인 단층이 과거 8천년 동안24회의 표면 파열 및 과거 900년 동안 4번의 재활성과 규모 약 8 M의 지진을 발생시켰다고 보고하고 있다. 또한 이 단층의 고지진 기록(1717, 1620, 1450, 1100 AD)과 그 주기를 감안할 때 향후 50년이내 파열될 가능성(약 30%)이 제기된 바 있다. 이 단층을 대상으로 지진 발생 이전의 단층대의 물리적, 화학적 거동 관찰 및 지진 감시 등을 목적으로 하는 국제과학시추 프로젝트(Deep Fault Drilling Project (DFDP) – Alpine Fault, New Zealand)가 수행되었다. 본 고에서는 해당 프로젝트를통해 수행된 주요 연구 활동 및 교훈(lessons learned) 들을 정리하고 주요 연구성과들을 소개하고자한다.

The Alpine fault, located in western South Island, New Zealand, is a fault that forms a part of the terrestrial boundary between the Australian and Pacific plates in southern New Zealand. Previous studies on this fault reported that the Alpine fault were suffered 24 surface ruptures in the past 8000 years, and recently four times reactivation with earthquakes of 8 magnitude in the past 900 years. In addition, some studies indicate that there is a possibility of reactivation within the next 50 years based on paleoearthquake records (in 1717, 1620, 1450, 1100 AD) and their cycles. An international scientific drilling project (Deep Fault Drilling Project [DFDP] ? Alpine Fault, New Zealand) was launched with the objective of investigating the physical and chemical behavior of the fault zone before earthquake occurrence, and monitoring seismicity on the fault. This review summarizes the major research activity and lessons learned from this project, and introduces its achievements.

Flash is the most popular 2D animation and game development software, supporting vector and media technology at the core, which enables the development of small and pithy games. It is widely used in Web animation, courseware, TV commercials, game development, and other works of design. In this paper, we propose a control movement function and auxiliary functions for an alpine skiing game based on ActionScript 3.0. The control movement function is designed with moving phases (i.e., free fall, sliding, projectile, and landing). The auxiliary functions include drawing path, start/restart movement, and saving the highest score. In addition, for the visual design of our game, we designed animations in connection with a character and background. In order to facilitate testing the friction, users can input a chosen friction value. Without user input, the friction default is set at 0.97.

Proliferation of shrubs at the expense of native forage in pastures has been associated with large changes in dry-matter intake and dietary components for grazing ruminants. These changes can also affect the animals’ physiology and metabolism. However, little information is available concerning the effect of pastoral-shrub grazing on the rumen bacterial community. To explore rumen bacteria composition in grazing yaks and the response of rumen bacteria to increasing shrub coverage in alpine meadows, 48 yak steers were randomly assigned to four pastures with shrub coverage of 0%, 5.4%, 11.3%, and 20.1% (referred as control, low, middle, and high, respectively), and ruminal fluid was collected from four yaks from each pasture group after 85 days. Rumen fermentation products were measured and microbiota composition determined using Ion S5TM XL sequencing of the 16S rRNA gene. Principal coordinates analysis (PCoA) and similarity analysis indicated that the degree of shrub coverage correlated with altered rumen bacterial composition of yaks grazing in alpine shrub meadows. At the phyla level, the relative abundance of Firmicutes in rumen increased with increasing shrub coverage, whereas the proportions of Bacteroidetes, Cyanobacteria and Verrucomicrobia decreased. Yaks grazing in the high shrub-coverage pasture had decreased species of the genus Prevotellaceae UCG-001, Lachnospiraceae XPB1014 group, Lachnospiraceae AC2044 group, Lachnospiraceae FCS020 group and Fretibacterium, but increased species of Christensenellaceae R-7 group, Ruminococcaceae NK4A214 group, Ruminococcus 1, Ruminococcaceae UCG-002, Ruminococcaceae UCG-005 and Lachnospiraceae UCG-008. These variations can enhance the animals’ utilization efficiencies of cellulose and hemicellulose from native forage. Meanwhile, yaks grazed in the high shrub-coverage pasture had increased concentrations of ammonia nitrogen (NH3-N) and branched-chain volatile fatty acids (isobutyrate and isovalerate) in rumen compared with yaks grazing in the pasture without shrubs. These results indicate that yaks grazing in a high shrub-coverage pasture may have improved dietary energy utilization and enhanced resistance to cold stress during the winter. Our findings provide evidence for the influence of shrub coverage on the rumen bacterial community of yaks grazing in alpine meadows as well as insights into the sustainable production of grazing yaks on lands with increasing shrub coverage on the Qinghai-Tibet Plateau.

Species diversity and habitat transformation are affected by climate change, both directly and indirectly, with correlations observed in terms of species specificity. Alpine and subalpine climate-sensitive plants frequently exhibit morphological plasticity by adjusting their physiological and reproductive processes to adapt to significant environmental changes. Bupleurum euphorbioides is a cold-adapted herb found on the rocky slopes of South Korea. Owing to climate shifts and human activities, its population has decreased. We conducted studies on pollen morphology, pollen viability, and sexual systems to better understand environmental adaptations. In this study, we observed extensive synchrony in the sexual maturity phases of B. euphorbioides flowers both within and across individual inflorescences. The population exhibited highly synchronized mass flowering, which may represent an adaptation to challenging environments where a brief breeding season necessitates the simultaneous blossoming of a large number of flowers. We documented the sexual expression of B. euphorbioides and distinctly observed protandry, wherein pollen presentation preceded stigma receptivity. All examined individuals of B. euphorbioides exhibited significant variation in pollen viability ranging from 0.04% to 95.54%, even within a single population. Meiotic failure or apomictic reproduction is possible in individuals with low pollen fertility. While fertile pollen grains displayed a prolate shape with a well-stained cytoplasm, sterile pollen grains were characterized by their smaller size and lack of stained cytoplasm. Therefore, more thorough observations of the meiotic behavior using an expanded range of plant materials are necessary to investigate the function of the distinct reproductive system of B. euphorbioides.

Red sorrel, as one of exotic weeds in Korea, was introduced along with imported cereals for concentrate feed or within the seed for forage production. The plant was dominated in grassland and reduced the quality of forage. In particular, this weed cause severe problem in alpine grassland. This study was carried out to investigate the effect and response of red sorrel and forage crops by foliar and soil applied herbicide application. Mecoprop(MCPP) and pendimethaline were selected by pre-field experiment trials and applied to control the red sorrel in grassland. Herbicidal activity of MCPP was 77.2% at 500ml/10a level and 82.8% at 750ml/10a level. However, seeds of red sorrel from bare land formed after foliar applied herbicide treatment were germinated and covered bare land. Pendimethalin was not reduced the rhizome growth grown from red sorrel root but retarded seedling growth of germinated red sorrel. The herbicidal activity of pendimethalin to the red sorrel seedling was 83.0%. 2 times application of MCPP at the rate of 750ml/10a was effective to control of red sorrel regrown from root and herbicidal activity was 93.2%. MCPP and pendimethaline treatment was not reduced growth of grass and have no herbicidal injury to forage crop seedling. Amount of MCPP and pendimethalin remained in grass plant was decreased from 20 days after herbicide treatment and could not be problem in livestock feeding.

This study assessed the efficiency of reducing soil erosion and suspended sediment through the restoration of alpine unauthorized and illegally cultivated fields, using the SWAT (Soil and Water Assessment Tool) model in the Mandae District. The results showed that in Scenario 5, which involved restoring unauthorized and illegal fields within forests, along rivers (banks), and in ditch areas were restored to their original land categories, achieved the highest efficiency in reducing average annual soil erosion and suspended sediment, with reductions of 8.1% and 4.5%, respectively. In particular, it was confirmed that the restoration of unauthorized and illegal fields within forested areas has a significant impact. This demonstrated that the restoration of unauthorized and illegal agricultural fields can substantially reduce the soil erosion and suspended sediment attributable to non-point source pollution. Our findings highlight the importance of managing these unauthorized and illegal agricultural activities in developing sustainable strategies within non-point source pollution management areas. This study is expected to provide important basic data to effectively establish water quality improvement strategies in the region of non-point source pollution management.

국내에서 광학 문자 인식(OCR)과 손글씨 인식 기술(HTR)은 탐색 단계를 넘어 광범위하게 활용되고 있다. 그런데 HTR 기술 개발은 대개 정부 주도 아래 이루어지고 있으며, 그에 관한 학계의 논의도 기술 내적 측면으로 제한되어왔다. 본 논문은 유럽에서 상용화된 텍스트 변환 플랫폼 트란스크리부스를 이용해 한국과 오스트리아 연구진이 국내의 대표적 등산 단체인 (사)한국산악회의 고문서를 아카이빙하고 분석하기 위해 국한문 혼용 HTR 기술을개발했던 과정을 사례로 분석한다. 본 논문은 민간 영역의 주도적인 참여, 연구진의 의사 결정 과정, 초국가적·학제적 협력 연구 양식, 아카이브의 공유 및 활용 방안 등에 주목함으로써, HTR 기술 개발을 통한 기록유산 고문헌의 아카이빙이 단순히 기술적인 문제가 아니며 고문헌의 공유재적 속성을 중심으로 한 시민사회의 공동체성과 역사성에 의존하고 또한 그를 매개로 전개될 수 있을 사안임을 주장한다. 나아가 공통된 문화 요소를 매개로 한 민간국제협력은 HTR 기술 개발의 주요한 견인 요인이 될 수 있다고 제안한다.

In South Korea, both OCR and HTR technologies are currently widely applied, while few attempts were made outside the governmental initiatives. This article offers reflections of a recent project for the construction of Corean Alpine Club’s corpus in collaboration with linguists from Innsbruk, Austria. Employing Transkribus, an AI-based transcription software created by the READ-coop, the project group successfully collaborated for the construction of the corpus and further tested the assets with a cross-cultural research about the historical correlation between mountaineering and environmental activism. The article concludes that nongovernmental international collaborations connected via a common interest for a specific cultural area may offer a significant pull-factor for HTR technology development.

본 연구는 독립훼손지 중 아고산대에 위치한 지리산국립공원 세석평전과 노고단 복원식생지를 대상으로 현존식생 분석 및 식생분포 특 성을 파악하여 중장기적인 모니터링 및 관리방안 수립을 위한 기초자료를 제공하고자 수행하였다. 현존식생 조사범위는 훼손지 일대 유역권 분포 현황을 고려하여 설정하였으며, 세석평전 조사면적은 55,037㎡, 노고단 조사면적은 166,599㎡ 이었다. 세석평전은 초본층에 의한 식 생피복도는 90% 이상 수준으로서 나지노출이 없었고, 관목층의 피복도가 60% 이상으로 안정화되어 있었다. 주요 출현수종은 구상나무, 사 스래나무, 쇠물푸레나무, 철쭉, 털진달래, 붉은병꽃나무 등 식재수종과 자연적으로 이입한 자생수종이 생육하고 있었다. 노고단은 신갈나무, 호랑버들, 철쭉, 털진달래, 미역줄나무 등이 우점하는 관목식생지가 52%로 가장 넓게 분포하고 있었고, 전반적으로 식생활착 상태가 양호하 였다. 노고단의 원식생은 신갈나무군락으로 추정되었고, 군부대철거지에는 귀화식물이 분포하고 있기 때문에 적극적인 관리가 필요하였다. 연구대상지는 장기적으로 주변 자연식생과 조화로운 식생경관으로 발달할 것으로 예측되었다. 향후 훼손지 복원모델은 인근 지역의 원식생을 고려하여 설정해야 할 것이지만, 복원 달성 목표는 실현가능한 수준의 목표를 설정해야 할 것이다.

This study was conducted to provide basic data for mid-to long-term monitoring and establishment of management plans by analyzing the existing vegetation and identifying the vegetation distribution characteristics for the restored vegetation in Nogodan and Seseokpyeongjeon in Jirisan National Park located in the subalpine zone among the independent damaged areas. Actual vegetation survey range was established in consideration of the distribution of the watershed around the damaged area. The surveyed area of Seseokpyeongjeon was 55,037㎡, and the surveyed area of Nogodan was 166,599㎡. In Seseokpyeongjeon, the vegetation coverage by the herbaceous layer was almost 90% or more, there was no bare exposure, and the coverage of the shrub layer was stabilized at 60% or more. The main emerging tree species were planted species such as Abies koreana, Betula ermanii, Fraxinus sieboldiana, Rhododendron schlippenbachii, Rhododendron mucronulatum var. ciliatum, and Weigela florida as well as natively migrated native species. In Nogodan, the shrub vegetation dominated by Quercus mongolica, Salix caprea, Rhododendron schlippenbachii, Rhododendron mucronulatum var. ciliatum, and Tripterygium regelii was the most widely distributed with 52% of the area, and the overall diet was good. The native vegetation of Nogodan was presumed to be a cypress colony. Naturalized plants were distributed in the military base demolition site, so active management was required. The study site was predicted to develop into a vegetation landscape in harmony with the surrounding natural vegetation in the long term. In the future, the restoration model for damaged areas should be set in consideration of the native vegetation of the nearby area, but the goal to achieve restoration should be set at a feasible level.

이 연구의 목적은 12개월 주기화 트레이닝을 통하여 비시즌과 시즌 직전, 시즌 이후의 무릎 및 허리의 근력 변화를 관찰함으로써 종목 특성에 맞는 운동프로그램의 효과를 알아보고자 하였다. 이 연구는 엘리트 선수 경력 10년 이상의 스노보드 알파인 선수 5명을 대상으로 실시하였으며, 조직 적응훈련(3주), 근비대 훈련(6주), 최대근력 훈련(4주), 근파 워 훈련(4주), 근력 유지훈련 (7개월), 휴식기(4주)로 구분하여 실시하였다. 이 연구의 결과로 비시즌과 시즌 직전의 등속성 무릎 및 허리의 최대근력과 근비율이 변화함을 알 수 있었으나, 선수별 근력 향상에 개인차가 발생하였다. 시즌 이후의 등속성 무릎 및 허리의 최대근력과 근비율 또한 변화하였으며, 선수별 근력 감소에 개인차가 발생하였다. 비시즌부 터 시즌으로 이어지는 주기화 트레이닝에 입각한 체력훈련 프로그램은 훈련된 운동선수의 근력 향상에 효과적인 것으로 확인되며, 시즌 이후 훈련강도 및 훈련량의 감소로 인한 근력감소가 확인되었으나, 선수에 따른 개인차가 발생하였다. 향후 주기화 트레이닝의 적용 시 활주 방향차이에 따른 근력 변화에 대한 연구가 기대되는 바이다.

The purpose of this study was to investigate the effects of exercise program that fits the characteristics of sports by observing changes in muscle strength and muscle ratio of knee and Lumbar after off-season, just before and after season through 12-month periodization training. This study was conducted on five snowboard alpine players with more than 10 years of elite athletes' career. The isokinetic muscular strength was measured before the periodization training, the isokinetic muscular strength was measured three times including measurement of isokinetic muscular strength after the season, which includes the training of snowboarding and the schedule of the game. The maximum muscle strength and muscle ratio of the isokinetic knee and Lumbar before the off-season and the season changed, but individual differences occurred in the improvement of muscle strength by player. The maximum muscle strength and muscle ratio of the isokinetic knee and Lumbar after the season also changed, but there was a personal difference in the muscle strength reduction by player. The physical fitness training program based on periodization training from the off-season to the season was confirmed to be effective in improving the muscular strength of the trained athlete, and the decrease in muscular strength due to the decrease in training intensity and training amount after the season was confirmed, but individual differences occurred according to the athlete. In the future, it is expected that the study on the change of muscle strength due to the gliding direction difference is expected when applying periodic training.
