Myiasis is usually caused by flies of the Calliphoridae family, and Cochliomyia hominivorax is the etiological agent most frequently found in myiasis. The first case of myiasis in a diabetic foot of a 54-year-old male patient in Argentina is reported. The patient attended the hospital of the capital city of Tucum$\acute{a} $n Province for a consultation concerning an ulcer in his right foot, where the larval specimens were found. The identification of the immature larvae was based on their morphological characters, such as the cylindrical, segmented, white yellow-coloured body and tracheas with strong pigmentation. The larvae were removed, and the patient was treated with antibiotics. The larvae were reared until the adults were obtained. The adults were identified by the setose basal vein in the upper surface of the wing, denuded lower surface of the wing, short and reduced palps, and parafrontalia with black hairs outside the front row of setae. The main factor that favoured the development of myiasis is due to diabetes, which caused a loss of sensibility in the limb that resulted in late consultation. Moreover, the poor personal hygiene attracted the flies, and the foul-smelling discharge from the wound favoured the female's oviposition. There is a need to implement a program for prevention of myiasis, in which the population is made aware not only of the importance of good personal hygiene and home sanitation but also of the degree of implication of flies in the occurrence and development of this disease.

Koh(袴) was a type of dress worn on the lower part of the body which was commonly used in the Northeast Asia. It was originally used by the Northern race for the need of nomadism or hunting. The origin of the Koh which appeared in the area would be found from the trousers of the Huns who influenced in the Northeast Asia, and became in the part of the Scythian culture. The Scythians are the nomadizing race inhabited in the Northern Caucasas on the wast of the Black Sea and influenced on the inland Eurasian steppe as the first typical horse-riding race. The objectives of Koh which had been worn in the Scythian, Mongolia, Korea as well as Japan as a part of Dongho dress and ornaments and to contemplate the transmission process by cultural exchange among different races for the period from 4th century to 7th century. 1. The Origination of the Koh The Koh was originated by the environmental factor to protect the cold in the North but also from the heat in the South, and was changed and developed as gradually satisfying to the needs of the times. In the Northeast Asia the Koh was in the class of the Northern Chinese garment, and was used widely by the horse riding Scythians who moved widely from the Eurasian inland to Japan. The oldest original which could reflect the type of the Northern clothes was a pair of trousers discovered in the Huns remains of Noin Ula. This showed the exact form of hunting clothes and had a similar form with the Korean female tro-users. Since the same form of trousers drawn on the wall painting of which was excavated 4-5th century ancient Koguryo(高句麗) tomb was the same form the trousers of Noin Ula seemed to be the original form of Koh in the Northeast Asia. 2. The Chinese Trousers It was the time of the King Mooryung(武靈王) in the Cho(趙) Dynasty B.C. 3th century that the trousers used regularly in China. However, the Koh had been used as undergarment which functioned for the protection of the cold not the horseriding garment. The trousers seemed to be not very obviously shown off since the Poh (袍) was long, but mainly used by the people from lower class. As people learned the adapted the trousers. It was essential for the times of war and quarrel. The king himself started wearing the Koh. The Chinese trousers were influenced by the Huns, the Northern clothes of the Scythian culture, and similar to the Korean clothes. 3. The Korean Trousers Korean was a race bared from the Eastern foreign group. It was obvious that the clothes was Baji-Jeogori(바지 저고리), the garment of the Northern people. This had the same form of the Scythian dress and ornaments which was excavated from the Mongolian Noin Ula. The Scythian dress and ornaments were influenced from the Ancient West Asia Empire and transmitted to the Northeast Koguryu by the horseriding Scythian. The trousers were kept in the traditional style by the common people in Korea were transmitted to Japan which were for behind in cultural aspect, as well as got used to the Chinese as the efficient clothes though active cultural exchange. 4. The Japanese Trousers The ancient Japanese clothes were influenced by the Southern factor but not the form of the Koh. As the Korean people group was moving towards Japan and conquer the Japanese in the 4-5th century, however, North Altaic culture was formed and at the same time the clothes were also developed. The most influenced clothes at this time were those of Baekge(百濟) and the trousers form called Euigon became the main form. Because of the climatic regional factor, it was tied not at the ankle but under the knee. From the view the ancient Japanese clothes disappeard about that time, it could be due to the conquest of the culturally superior race but not the transmission of the culture. In the latest 7th century both the Chinese and Japanese dress forms were present, but the Dongho(東胡) dress and its ornament from Korea was still the basic of the Japanese dress form.

얼록동사리(Odontobutis interrupta)의 생태적 특징을 연구하기 위해 2021년 1월부터 2021년 12월까지 금당천에서 조사를 실시하였다. 본 종의 서식지 하상구조는 모래(sand)와 진흙(mud)이 풍부하였다. 수심은 평균 48(21~124)cm로 다소 깊었으며, 유속이 0.24(0.08~0.36)m/sec로 느렸다. 암수 성비는 1 : 0.98 이었고, 채집된 개체의 전장 범위는 23mm에서 162mm 이었다. 전장빈도분포도에 따른 연령은 5월 기준 전장이 23~59mm는 만 1년생, 60~99mm는 만 2년생, 100~139mm는 만 3년생, 140~162mm는 만 4년생 이상으로 추정되었다. 2차성징으로 생식적 유두(genital papilla)는 암컷의 경우 원통형 모양으로 끝의 안쪽이 비어 있으며 직경이 수컷에 비해 컷으며 수컷은 끝이 뾰족하여 원뿔 모양이었다. 성적성숙이 이루어진 수컷은 혼인색으로 복부와 몸통 전체가 검은색을 띄었다. 암컷의 경우 60~69mm에 해당하는 일부 개체만 성적성숙을 하였고 70mm 이상이면 모두 성적성숙을 하였다. 수컷은 70~79mm에 해당하는 개체 중 일부만 성적성숙을 하였고 80mm 이상에서 모두 성적성숙이 이루어졌다. 산란시기는 5월부터 시작되어 7월에 끝났으며(수온 19.6~29℃) 산란 성기는 6월로 추정되었다(수온 26℃). 포란수는 평균 2,473(883~4,955)개 이었고 성숙란은 짙은 노란색 구형으로 직경이 1.42(1.20~0.54)mm 이었다. 전장-체중과의 상관관계식은 BW=0.0000006TL^3.21로 상수 a는 0.0000006를, 매개변수 b는 3.21 이었다. 비만도 지수는 평균 K=1.67(1.18~2.43) 이었고 기울기(Slope)는 0.116로 양의 값을 나타내었다.
