This study was carried out to propose the baseline data for in situ conservation by analyzing environmental and growth characteristics in Pedicularis hallaisanenesis habitats. P. hallaisanensis habitats, according to investigations, were located on the slope of southwest at an elevation of 1,400 m in Mt. Gayasan and on the slope of southeast at an elevation of 1,500 m in Mt. Hallasan. Pedicularishallaisanensis habitats. Also, habitats were found at the grassland with no upper vegetation. In the study sites, soil pH and soil organic matter were 4.9-6.5 and 4.4-8.1%, respectively. A total of 55 vascular plants taxa were identified in ten quadrats in two habitats, of which 25 were inhabited in Mt. Gayasan and 37 in Mt. Hallasan. Current status of P. hallaisanensis habitats were very vulnerable with the pressure of the vegetation constantly threatening the species' survival. Thus, concrete conservation plans including diverse factors as light intensity, temperature and genetic analysis to protect natural habitats should be set up as soon as possible.

With respect to the quantity, quality and social value of forest jobs, we have developed three major criteria and 11 indicators for evaluating decent forest jobs. The importance and weighted value of the criteria and indicators were investigated through a survey which was conducted on 50 experts involved in Governmental Forest Job Committee, academic and different groups of communities. The 35 experts responded to the survey chose the 'job creation potential' as the most important criterion, and they recognized the 'job quality' has a relatively higher importance than the 'social contribution'. The survey results showed that 'political will' and 'job security' have the highest weighted values among indicators while 'wage level' has the lowest value. The developed criteria and indicators are able to be used as a means of evaluating degree of decent forest jobs for both new and existing jobs.

This study aimed to investigate responses of plant growth and photosynthesis to different kinds of covering materials with selective light transmit for red leaf lettuce (Lactuca sativa L.). Experimental pot design was attached UV blocking filter, red filter, blue filter, and green filter. The kinds of covering materials showed significant results for plant growth especially control, UV blocking filter, and red filter. The photosynthetic rate and anthocyanin content of red leaf lettuce were higher in control and UV blocking filter than others. The quality of red leaf lettuce was low in red, green, and blue film treatments because of too low anthocyanin content.

도시하천유역이나 복합유역 등 지역적 성향을 고려한 도달시간 산정에 관한 연구는 현재까지도 미흡한 실정이다. 소규모 유역의 홍수량을 산정할 경우 유하시간보다 유입시간 비중이 상대적으로 크다. 그러나 유하시간만을 고려하여 도달시간을 산정할 때, 소규모 유역의 경우 하도가 없고 유역면적이 5km² 내외 또는 하도의 저류 효과를 기대할 수 없는 경우 도달시간이 짧아 홍수량이 과대 산정된다. 이를 극복하고자 재해영향성평가등의 협의 실무지침에서는 도달시간 이외에 매개변수인 저류상수를 인위적으로 증가시키는 방법을 제안하고 있다. 하지만 이 방법 역시 유역의 물리적인 특성을 나타내는 변수를 왜곡한다는 근복적인 문제를 완전히 해결하지 못하였다. 이에 본 연구에서는 기존 중·대규모 하천을 대상으로 수행된 연구결과를 바탕으로 제안된 홍수 도달시간 산정방법의 한계를 극복하고, 유입시간이 지배적인 소규모 복합유역에 적용 가능한 도달시간 산정방안을 제시하고자 한다. 이를 위해 실증실험을 통해 기존 유입시간 산정식을 개선하고, 도시수문 모니터링 시범유역에 적용하여 정확성을 평가하고자 하였다. 먼저, 홍수도달 시간 측정을 위한 강우유출 실내 실험장치를 제작하였다. 실험장치는 본체(길이3m×폭1.2m×높이0.8m)와 경사조절 장치(0~15도)를 포함하고 있다. 본체 전면부를 타공(ø10mm)하고 상·하단에서 지표와 기저유출을 집수하여 티핑버킷으로 유량을 측정하였고, 토체 내에는 토양수분센서를 설치하여 강우유출 발생시간 동안 토양수분 변화를 측정하였다. 본 연구에서는 하도흐름인 유하시간(Kraven 공식)을 계산하여 도달시간을 산정하기 보다 지표면 흐름인 유입시간(Kerby 공식)에 보정계수를 도입하여 도달시간을 산정하는 방안을 검토하였다. 실험 결과, 불투수 면적비율이 증가함에 따라 도달시간은 감소하고, 불투수 유역이 하류에 위치할수록 유출발생시간이 빨라졌다. 실증실험 결과를 바탕으로 도시수문 모니터링 시범유역에 적용하여 기존 유하시간과 저류상수를 보정하는 도달시간 산정방식(연속형 Kraven)과 유입시간을 보정한 도달시간 산정(수정 Kerby)으로 도출된 유출량을 실측 유량과 비교하였다. 그 결과 제안된 홍수도달시간 산정식에서 모의된 홍수량이 기존 방식과 유사하거나 우수한 첨두홍수량을 보였으며, 설계자 임의성이 배제된 일관성있는 해석값을 제시해 줄 것으로 판단된다.

At present, domestic archives within the realm of performing arts predominantly focus on recording through videos, yet they often lack comprehensive documentation of crucial production processes and content services. Recognizing the contemporary significance of archival content services, this study analyzes the archival content within the national performing arts archives websites of the United Kingdom and the United States, serving as international benchmarks. The findings extrapolate insights and implications to propose enhancements for the Museum of Performing Arts in the National Theater of Korea. The analysis focused mainly on the missions and visions on the websites, examining 107 contents from the UK National Theater, 27 from the United States, and 9 from Korea. The suggested improvements encompass clarifying target users and execution tasks in the mission and vision statements, fostering expert collaborations, incorporating preview features, curating content with a single theme, and organizing a comprehensive list on the National Theater's YouTube channel.

The Cheonjeon-ri petroglyph is inscribed with shale formation belonging to the Daegu Formation of the Gyeongsang Supergroup in the Cretaceous of the Mesozoic Era. This rock undergoes thermal alteration to become hornfels, and has a high hardness and dense texture. Rock-forming minerals have almost the same composition as quartz, alkali felspar, plagioclase, calcite, mica, chlorite and opaque minerals, but calcite is rarely detected in the weathered zone. The petroglyph forms a weathered zone with a certain depth, and there is a difference in mineral and chemical composition between weathered and unweathered zones, respectively. The CaO contents of the weathered zone were reduced by more than 90% compared to that of the unweathered zone, because calcite reacted with water and dissolved. As a result of calculating the surface weathering depth for the petroglyph with the transmission characteristics of X-rays, depth of the parts in falling off and exfoliation showed a depth of about 0.5 to 1 mm, but the weathering depth in most areas was calculated to be about 3 to 4 mm. This can be proved by the contents and changes of Ca and Sr. The surface discolorations of the petroglyph are distributed with different color density, and the yellowish brown discoloration is alternated with a thin biofilm layer, showing a coverage of 79.6%. Therefore, periodic preservation managements and preventive conservation monitoring that can effectively control the physicochemical and biological damages of the Cheonjeonri petroglyph will be necessary.

Aside from enriching spirituality, religiously-themed museums play a crucial role in resolving conflicts among the nations peripherally or various cultural groups in a broad sense. Relatively speaking, Korea has achieved a peaceful multi-religious society, yet the 2019 pandemic caused certain religious conflicts to surface or perhaps resurface. Since the 2000, due to the increasing number of migrants, there has been increasing awareness of the need to accommodating even greater levels of religious diversity. Accordingly, this study aims to apprehend various educational programs and exhibitions that have been developed by St. Mungo's Museum of Religious Life and Art, the State Museum of the History of Religion, and the Museum of World Religions in multi-ethnic societies such as the UK, Russia, and Taiwan. Therein, it will be determined how these museums contribute to mutual understanding and interaction and this research will suggest the development of a religiously-themed museum capable of resolving a number of social conflicts and enriching the diversity of its nation.
