A magnetic resonance imaging test was performed on a 56-year-old male patient, who visited with a one-month history of painless swelling at the popliteal area of the left knee. A popliteal cyst and non-calcified loose body in the cyst were identified. Synovial chondromatosis was diagnosed from a histology examination by excision and biopsy. This paper reports this case of extra-articular synovial chondromatosis of the knee with a review of the relevant literature.

Objectives: The aim of this study was to investigate airborne pollen counts, inhalant allergen sensitization rate, and allergic disease prevalence among elementary school children in Ulsan, South Korea during 2012-2018. Methods: Burkard samplers for pollen were installed on rooftops in suburban and urban areas in Ulsan. A 24-hour sampling of airborne allergens was conducted six days/week from January 1, 2013 to November 31, 2018. Skin prick tests were done with a total of 4,246 primary school students residing in urban and suburban areas in 2012, 2014, 2016, and 2018. This study examined sensitization to 20 major inhalant allergens. Results: The highest monthly counts of airborne pollen were observed in April and September each year. Among the pollen identified over the six years, pine showed the highest pollen counts (44.3%), followed by oak (22.3%), alder (6.3%) and Japanese hops (4.3%). Tree pollen predominated from March to June, and weed pollen predominated from August to October. Higher sensitization rates for inhalant allergens were observed in Dermatophagoides farinae (42.4%), Dermatophagoides pteronyssinus (43.6%), cat fur (12.1%), birch (9.9%), oak (9.6%), and alder (8.7%). The inhalant allergen sensitization rate was highest in the group with comorbidity (asthma and/or rhinitis and atopic dermatitis), and respiratory allergic disease (asthma and/or rhinitis) was higher than that of atopic dermatitis. Conclusion: Both the counts of tree pollen in the air and the sensitization rate for tree pollen were high in Ulsan. The temporal change in respiratory allergic diseases was similar to that for the sensitization rate of tree pollen, such as oak. In the future, it is considered that additional continuous research on various inhalant allergens and pollen should be conducted.

In the past, each villages of ULSAN had their own SUNGHWANGDANGs. Village folks held an annual ritual for a ghost called GOLMAEGI. That ritual, which was a form of festival supervised by the village community, was the opening of seasonal customs. People called the ritual JISINBOPKI. It was a type of NONGAK in which musicals and dramatic factors made a harmony. Usually its lyrics were called 'SUNGJUPURI'or 'JISINBOPKI' song. At that moment, villagers, thumping on the ground with their feet, danced 'DUTBEKI' to awake the sleeping ghost SUNGJUJISIN. After this ritual, the music band started to visit people's house after house around the town playing PUNGMUL NOLI which consisted of SOGO NORUM, JAPSACK NORUM. The whole proceeding of these performances did not have a definite name. Villagers prayed to SUNGJUJISIN for the prevention of bad luck in their home. This study have arranged the type of MAEGUCHIGI, which is a kind of wishing NONGAK, on the basis of two preceding primary documents. And the other is about JISINBOPKI of ULSAN district that was shown in ULSAN YUSA written by a local historian, KIM SUKBO, of ULSAN. The process of arrangement is as follows. At first, considering the implication of this NONGAK, the definite title of it was designated as ULSAN MAEGUCHIGI. And then, it was given its genre and type within NONGAK.

This paper tried an approach of oral literature as the research subject of Soeburi song in Ulsan. First, UlsanSoeburi song is meaningful as materials collected in Ulsan such as Hansil, Dodoekgol, Dudong and Byeongueong. In addition, it is related to regional identity as song native to Ulsan, which has prototype and archetype. And it shows that Ulsan is the city as well as hometown of Soeburi(meaning ' iron manufacture'). The characteristics of lyrics are different between Hansil Soeburi song and Dodeokgol Soeburi song. Jeiman Choi is considered as a good oral literature poet, because he is a performer who is faithful in official structural principal and in original lyrics(archetype) of Soeburi song. Therefore, SoeburiBulmei song of Jeiman Choi signifies aesthetic meaning, having lyrics which make to feel labor's purity and sacred and melody which overcomes labor's difficulty through united action. On the other hand, SoeburiBulmei song of Dalo Kim in Doseokgol shows that he is a extemporaneous performer even though he performs based on official structural principal. In this paper, transmission and changes of UlsanSoeburi song are divided into basic type, frequent shift type and overall type. 'Basic type' originates from Jeiman Choi's Soeburi song in Hansil. 'Frequent shift type' was created by combining SoeburiBulmei song of Dalo Kim in Doseokgol and SoeburiGeumjul song in Ulsan. 'Overall type' is current Soeburi song, which was created by adding Bulmei song for lulling a baby in Byeongueong near Dalcheon region and Seoknyanggan(smithy) Bulmei song. UlsanSoeburi song is being passed down continuously, strengthening the identity as a representative folk song in Ulsan through endless process of transmission and changes.

모든 것을 긍정적으로 바라보며, 정직과 성실만으로 세상살이를 하는 일. 아름다운 이야기지만 그렇게 사는 일이 말처럼 쉬운 것은 아니다. 그런데, 그 정직과 성실만이 세상을 밝히는 최고의 진리라는 확신으로 살아온 사람이 있다. 심완구 울산광역시장. 그가 울산의 광역시 승격을 주도할 수 있었던 것도, ‘21세기 산업수도 울산 건설’을 위한 장기적이고 야무진 계획을 수립하고 추진할 수 있는 것도, 다방면으로 많이 알아야 국민을 위한 제도로 된 정책을 낼 수 있다는 생각에서 바쁜 중에도 학업을 계속했던 것도 바로 그 확신에 바탕을 두고 있다. 항상 시민의 목소리를 향해 귀를 열어두고, 울산광역시민과 함께 2천 년대 제2의 산업 수도 건설을 위해 오늘도 바쁜 하루를 보내고 있는 작은 거인 심완구 시장의, 미래도시 울산 건설의 청사진을 소개한다.

최근 이상기후로 인해 우리나라의 강수량과 집중호우가 증가하고 있으며, 태풍의 빈도는 낮아졌지만 태풍의 강도가 높아지는 추세를 보이고 있다. 지난 2002년 태풍 '루사', 2003년 태풍 '매미', 2006년 태풍 '에위니아' 그리고 2016년 태풍 '차바' 등에 의해 울산지역에서는 집중호우로 인한 많은 인명과 재산피해가 발생하였다. 2016년 태풍 '차바' 당시 300년 빈도를 초과하는 시간당 104.2mm의 강우가 발생했으며, 울산 시가지를 비롯한 전역에 막대한 침수피해가 발생하였다. 본 연구에서는 2차원 도시유출모형인 XP-SWMM모형을 이용하여 2016년 태풍 '차바' 당시에 울산 시가지 중심인 우정혁신도시를 비롯한 침수가 발생한 태화 우정시장 일대에 대한 침수원인 분석을 하였다. XP-SWMM모형을 이용하여 우수관거에 흐르는 홍수수문곡선을 산정하고 관거의 용량을 초과하여 범람한 유량은 2D 모델링을 통하여 침수분석을 하였다. 침수분석결과는 연구지역의 실제 침수심 및 CCTV자료 분석을 통한 침수심과 비교하였다.

C/C++에는 다수의 메모리 취약점이 존재하며 ASan은 낮은 오버헤드와 높은 탐지율로 이러한 메모리 취약점을 탐지하기 위해 광범위하게 사용되고 있다. 그러나 상용 프로그램 중 다수는 메모리를 효율적으로 사용하기 위해 Custom Memory Allocator(CMA)를 구현하여 사용하며, ASan은 이러한 CMA로부터 파생된 버그를 대부분 탐지하지 못한다. 이를 극복하기 위해 본 연구에서는 LLVM IR 코드를 RNN 신경망에 학습하여 CMA를 탐지하고, ASan이 CMA를 식별할 수 있도록 수정하여 CMA로부터 파생된 메모리 취약점을 탐지할 수 있는 도구인 CMASan을 제안한다. ASan과 CMASan의 성능 및 CMA 관련 취약점의 탐지 결과를 비교·분석하여 CMASan이 낮은 실행시간 및 적은 메모리 오버헤드로 ASan이 탐지하지 못하는 메모리 취약점을 탐지할 수 있음을 확인하였다.
