The genus Xylaria, a large and diverse group within Ascomycota, plays an important role in forest ecology as decomposers. Several new Xylaria species have been recently identified. In this study, the morphological and molecular characteristics of Xylaria species found in Korea were analyzed based on the latest classification systems. Notably, species with characteristics similar to Xylaria cubensis and X. rogersii, which were not previously reported in Korea, were identified. X. cubensis grows on rotten wood and is characterized by brownish clavate stromata with rounded apices and small, dark ascospores. X. rogersii, found in Magnolia spp., has long stromata with a dark-brown, fine-striped outermost layer and subhyaline to yellowish single-celled ascospores. Genetic analysis using a combined dataset of internal transcribed spacer, β-tubulin, and RPB2 sequences revealed that these species form a distinct group separate from other known species. Further investigations included detailed macro- and micromorphological studies, as well as molecular analyses to establish their taxonomic positions more precisely.
We see that the method of calculating the moon's position in the celestial sphere is little different from the method currently used. Currently, an elliptical model is used, while Sechoyuhwi and Chongzhen Lishu(崇禎曆書) use a four-epicycles model descibed in Lixiang Kaocheng(曆象考成) when calculating the equations of the Moon. The equation of center( EoC) calculated in this way has little difference from the currently calculated EoC. Considering the four-cycles model, the EoC occurs due to the center difference of the moon's orbit. The evection and variation occur when the sun exerts gravitational perturbation on the moon's orbit, and those are expressed as the 2nd and 3rd equations. However, when calculating the moon's position, Sechoyuhwi and Chongzhen Lishu used the apparent solar time. therefore these almanacs deal with another equation which is not the same as the 4th equation described as the equation of annual inequality. Furthermore these calendars consider the longitude reducing when the longitude along the lunar path in the celestial sphere is converted to that along the ecliptic. In this case the same as the 5th equation described as the equation of reduced ecliptic is corrected. When the ecliptic latitude were calculated, these calendars have considered the latitude evection of the lunar inclination to the ecliptic with the two-cycles model. At the time when Sechoyuhwi was written, Joseon’s lunar position tracking was at the highest level before Newton knew how to do it.

본고는 피터 무어가 찍은 백남준의 <필름을 위한 선> 퍼포먼스와 에릭 크롤이 찍은 <TV 부처> 전시에서의 기록사진을 살피며, 미술 아카 이브에서 작품과 함께 등장하는 작가 모습을 담은 사진이 작가가 화면과 어떠한 관계를 맺고자 하는지 발견케 한다는 점을 논한다. 이들은 작가가 자신의 작업과 마주하는 순간을 담은 단편적 기록일 수 있으나 그것은 작가 자신이 화면과 마주하는 의도된 시선과 태도를 드러낸다. 이후 본고는 이를 작품과 감상자(작가)가 연합된 객체를 구성한다는 하먼의 예술객체 개념 하에 살피며, 이런 혼성객체 내부에서 지각자와 감각객체의 '진솔한 몰입'은 예술경험을 들여다 볼 수 있는 기회를 제공한다고 본다. 이를 통해 본고는 기록사진이 제1관객이자 모범적 관객으 로서의 작가가 어떠한 태도로 작품과 함께하며 작품과 진솔한 관계를 맺는지 살필 수 있는 기회를 제공함을 주장하며, 이는 결국 사진을 보는 이들과 해당 작품의 미래 관객에게 작품을 더욱 깊이 이해하고 해석할 수 있는 일종의 형식과 틀을 제시한다고 말하고자 한다. 이러한 주장은 하먼의 예술객체를 감상자뿐 아니라 생산자이자 창작자까지 포함하여 탐색하려는 시도이기도 하다.
Recently, the number of elderly driver accidents has been steadily increasing. EDR(Event Data Recorder) helps a lot in understanding traffic accidents. In particular, as anxiety about SUA(Sudden Unintended Acceleration) increases, EDR data is playing an important role in accident analysis. In this study, EDR data of an accident vehicle suspected of SUA was analyzed to identify traffic accident circumstances and detailed accidents. Experimental results were derived and analyzed by simulating the situation of SUA while driving a car. As a result, it was found that normal braking is performed when the brake pedal is operated even in dangerous situations such as mechanical defects and driver malfunctions. Rather than finding the cause of an accident after a traffic accident, countermeasures are needed to prevent mechanical defects and driving malfunctions before a traffic accident.

This study aimed to obtain basic information on the indoor environmental hygiene of non-disinfected libraries used for paper records preservation in the Nara Repository of National Archives, Korea. Microorganisms were investigated in dust samples collected from bookshelves of five libraries using the swab method. Bacterial concentration ranged from 6 CFU/m2 up to 1,730 CFU/m2 . A total of 11 bacterial species belonging to five genera were identified, with Bacillus being the predominant genus. Some bacterial species forming colonies with pigmentation on TSA media were also present. No bacterial species capable of producing cellulases were found. However, one species that could have harmful effects on human health was discovered. For fungi, concentration ranged between 6 CFU/m2 to 1,660 CFU/m2, and a total of six fungal species belonging to five genera were found. Some fungal species forming pigmented colonies on PDA media were also present. Additionally, three species that could have harmful effects on human health were identified. This study’s data suggests that microbial contamination in the dust is relatively low, but the dust in the bookshelves of non-disinfected libraries at the Nara Repository requires management. This is the first report conducted on microorganisms in the dust of bookshelves at the National Archives in Korea.
The purpose of this study was to record for the first time in Korea the presence of Melanoides tuberculata (an invasive alien species), which was confirmed during the “National Survey on the Status of Alien Species” in Jukdang stream (also known as Guppy Stream, located in Icheon, Gyeonggi Province), which is affected by the year-round discharge of heated effluent from a large semiconductor factory and where various tropical organisms, including ornamental fish, appear due to artificial release. A Total of 52 specimens were collected, and they can be visually distinguished from native melanian snails by their reddish-brown flames and spots. Genetic analysis further confirmed the species as Melanoides tuberculate. Melanoides tuberculata typically inhabits tropical climates, but its presence has been confirmed in altered aquatic environments such as Jukdang stream, where the water temperature remains warm even in a temperate climate. This indicates the need for further monitoring of domestic streams with similar conditions, particularly those receiving heated effluent, like Jukdang stream. Additionally, due to its strong reproductive capacity, including parthenogenesis, and its adaptability to various environments, there have been cases where the populations of Pomacea lineata and Aylacostoma tenuilabris have declined. This suggests that Melanoides tuberculata may have a competitive advantage in interspecific competition, potentially suppressing native species populations if it spreads within the domestic ecosystem. Melanoides tuberculata serves as an intermediate host for parasites that can cause diseases in both humans and animals, raising public health concerns in many countries. There is also a significant risk that it could be mistaken for native melanian snail species and consumed, which necessitates a high level of caution.
