  • This article deals with some issues with respect to the Mahan pottery excavated from the tombs. Pedestal jars with cover, small round-bottom jars, cylindrical pottery etc. had appeared in the interaction with the northern region in the dimension of the southern Korean peninsula. Especially, these relics had an important role at the route connecting the midwest region, Chungcheong(忠淸) inland and Yeongnam(嶺南) region. By this stage, the iron culture was similar to each other in the southern Korean peninsula. In addition to the inland route, the coastal passage along the west coast seems to have been used. Such signs are found in cylindrical pottery and Pedestal jars with cover. It was probably a natural phenomenon that the most powerful forces of Mahan appeared at this crossroad of cultural exchange. The unique style of Mahan pottery such as double-rim pottery had been established since the third century. After the third century, Mahan pottery varied by region depending on the tomb style. The difference roughly matches with the variations of the tomb style. But at the region of Bungumyo(mounded tomb), specific pottery such double-rim pottery had been prevalent than in other regions. And a specific style had been used in a narrow range. The pottery spread to the neighboring regions in the course of interaction and were also used in ritual practices.

  • This study aimed to prepare basic data for protecting the habitat of Fairy Pitta Pitta nympha and coping with climate change by detecting songs with bio-acoustic recording technology and identifying phenological characteristics in protected areas in Korea. The study sites were 36 protected areas nationwide. Data were collected between January and December 2019, and the analysis period was from May 1 to August 31, 2019. The main results are described as follows. Firstly, songs were detected in 22 out of 36 study sites. Frequency analysis results of songs show that high frequency was observed in southern inland, including Jeju island, and the area with the highest latitude was Seoraksan National Park. Secondly, the first song was observed in Hallyeohaesang National Park Geumsan on May 14, 2019, and the last song was observed in Ungok wetland in Gochang on August 6, 2019. Thirdly, circadian rhythm analysis results of songs show that the frequency rapidly increased at five o'clock in the morning, peaked at six o'clock, and then decreased afterward. Fourthly, seasonal cycle analysis results of songs show that they were observed from May 14, 2019 to August 6, and the day with the highest accumulated frequency of songs was June 3, 2019 (Julian date: 154). The average temperature of the day the songs were detected was 17.4℃, the average precipitation was 0.02mm, and the average humidity was 82.6%. Fifthly, a correlation analysis result between Fairy Pitta's songs and meteorological factors shows that temperature indicated a negative correlation with Fairy Pitta's songs (p<0.001), but precipitation (p=0.053) and humidity (p=0.077) did not indicate a statistical significance (df=471). This study is significant in that it confirmed the distribution of Fairy Pitta's songs using bio-acoustic recording technology in protected areas nationwide and identified their ecological characteristics by precisely analyzing the relationship between the song period and meteorological factors.
