눈부신 하늘과 드넓은 초원을 지닌 몽골은 1년 중 260일 가량이 맑은 날씨라서 '푸른 하늘의 땅(Land of Blue Skies)'로 불린다. 그러나 몽골은 영아사망률이 100명당 52명에 달할 정도로 보건.의료 환경이 열악한 '의료의 오지'다. 의료시설의 혜택을 못 받는 이곳에 한국가톨릭의료협회 해외의료선교 봉사단이 사랑과 인술의 씨앗을 뿌리고 돌아왔다. 그들의 의료봉사 활동을 동행 취재했다.

"삼월하늘 가만히 우러러보며 유관순 누나를 생각합니다. 옥속에 갇혔어도 만세부르다 푸른하늘 그리며 숨이졌대요~" 강소천 선생이 지은 유관순 노래다. 삼월이면 어김없이 다가오는 삼일절인데, 삼일절은 인쇄인에게도 특별한 날이다. 1919년 3월 1일 만세운동은 보성사에서 '독립선언서'를 '인쇄'해 배포함으로써 전국적으로 확산할 수 있었기 때문이다. 2013년 94주년 삼일절을 맞아 독립운동에 앞장섰던 보성사와 인쇄인들에 대해 알아본다.

고추로 유명한 경상북도 영양군은 전국 최초의 '영양반딧불이생태체험마을특구' 가 있는 곳이다. 이곳에는 '자연생태공원' 과 더불어 '영양반딧불이천문대' 가 위치하고 있다. 반딧불이는 공기가 맑은 청정한 자연 환경과 밤하늘이 어둡고 깨끗한 곳에서만 서식한다고 하는데, 영양은 전국에서 반딧불이가 가장 많이 서식하는 곳이다. 그 만큼 밤하늘의 별도 셀 수 없이 많이 볼 수 있는 천문대이다.

Japanese pine sawyer (JPS), Monochamus alternatus is a vector insect of pine wood nematode, Bersaphlenchus xylophilus in Korea and Japanese pine forest. This study was to evaluate the possibility of biological control of JPS with Korean entomopathogenic nematodes (EPNs). Korean EPNs (Heterorhabditis sp. Gyeongsan, Steinernema carpocapsae GSN1, S. glaseri Dongrae and S. longicaudum Nonsan strain) were infested bate insect, Galleria mellonella in log of dead pine tree. Result showed that, S. carpocapsae GSN1 strain has the highest pathogenicity. Heterorhabditis sp. Gyeongsan and S. carpocapsae GSN1 had infested bate insect, which located in 7.5 cm depth of pine log. EPN has pathogenicity against larva and adult of JPS. Spray application of EPNs against adult of JPS, Heterorhabditis sp. Gyeongsan strain showed higher pathogenicity than S. carpocapsae GSN1 strain. EPN infested larva of JPS was detected on bark spray treatment with S. carpocapsae GSN1 strain in dead pine log that naturally infested larva of JPS however, no EPN infested JPS was detected on soaking of pine log with suspension of S. carpocapsae GSN1 strain. Though EPN had found with low efficacy against JPS but still possible to apply to control the boring insect pest as they can control log dwelling insect.

To develope a microbial pesticide for the control of mulberry longicorn beetle, Apriona germari, Beauveria spp. were isolated from the infected Apriona germari larvae. The morphology of Beauveria spp. was observed by phase contrast and scanning electron microscope. In addition, the Beauveria spp. isolated from Apriona germari were identified by the random amplification of polymorphic DNA using polymerase chain reaction. The results showed that the Beauveria spp., SFB-1A and SFB-3A, isolated from Apriona germari were identified with B. bassiana and B. brongniartii, respectively, suggesting that the random amplification of polymorphic DNA is effective for the identification of Beauveria spp.

A morphological study of Korean Fimbristylis was conducted in order to clarify the taxonomical position and scientific names among species. It was determined that the anther size and style length are important characteristics for the species-level identification of Fimbristylis. It was confirmed that Fimbristylis ovata (Burm.f.) J. Kern, which is recorded in the literature but which has no sampling specimens in Korea, grows on the grassland on Marado Island. According to this study, the genus Fimbristylis in Korea is classified into a total of 21 taxa, including four sections, nineteen species, and two varieties.

The DOM (: Digital Optical Method), which measures the turbidity of chimney smoke, is a method of calculating the turbidity by setting the area to be measured and the contrast area using a low-cost digital camera that can be easily obtained. However, it is difficult to measure clouds and white smoke in a cloudy sky. In this paper, we develop a background sky type model that can represent the background sky and classify the type by periodically photographing it with a digital camera to solve this problem. In addition, based on the model, we develop a filter to optimize white smoke image and prove its excellence through experiments.

We studied the habitat sites of Siberian flying squirrel in Guhak-ri, Sillim-myeon, Wonju-si, Gangwon-do from March to April in 2009. We were found total 30 points of inhabitation trace types; nests 15 points(Tree nest types were 13 points, used Tree hole types hole types were 2 points) and droppings 15 points. We observed 3 individuals of Siberian flying squirrels and founded that 2 individuals of them used tree holes, and another individual used tree nest which were located in branches of Pinus densiflora. Most utilized nest trees of Siberian flying squirrel were Larix leptolepis, and also used Pinus densiflora, Betula davurica, Styrax japonica, Cornus controversa, Acer mono. Droppings trees were Prunus sargentii, Cornus controversa, Quercus xmccormickii, Acer palmatum, Acer palmatum, Betula davurica. Through the observation, we defined that flying squirrels mainly used Conifer trees as nest sites, and decideous trees as droppings.

We measured night sky brightness (NSB) over the downtown using a Digital Single Lens Reflex (DSLR) camera combined to a small telescope for educational purpose, considering that most secondary schools are located in urban areas and have limitation in the equipment for astronomical observation. Raw format images from DSLR camera are not affected by various camera settings except for the ISO, and the typical photometric uncertainty including filter transformation is about 0.1 mag. Near the zenith, the NSB of the B, V, and r-band is 17.5, 17.1, and $16.9mag\;arcsec^{-2}$, respectively. The approximate limiting magnitude is derived to be 17.5 mag at B-band and 17 mag at V, r-band. A large scale artificial light close to the observation site is the dominant cause for making observing condition worse, increasing the NSB by $0.6mag\;arcseec^{-2}$ regardless of the altitude and filter.
