The investigation of mollusks and the swimming-out of pre-larva fish from mussels in the Lake Uiam was carried out from March to November in 1981. The results of these investigations were summarized as follows: 1. The dominant species of mollusks living in the Lake Uiam is Corbicula fluminea. 2. The size of Semisulcospira gottschei and Corbicula fluminea is larger in the southern parts of the lake and gets smaller toward the north of the lake. 3. Semisulcospira gottschei and Corbicula fluminea are collected from all areas in the lake, regardless to the soil texture and water depth. 4. The number of species of mollusks in the lake is two classes, three orders, seven familes, including sixteen species. 5. The swimming-out rates of pre-larva fish are 43.9%, 4.5%, and 1.9% in Anodonta fukudai, Lanceolaria acrorhyncha, and Unio douglasiae respectively. 6. The authors confirmed one more mussel(Lanceolaria acrorhyncha) from which pre-lava fish have swum out. 7. The swimming-out of pre-larva fish from mussels takes more than a month.

The auther has studied the attachment of glochidia of A. fukudai to the fish in the Lake Uiam. This research is one of the ecological studies on the molluscs in this lake. The attachment of the glochidia to the fish body is summarized as follows: 1. The fish attached the glochidia of this mussel are 5 species including Carassius carassius, Oryzias lapites, Pseudorasbora parva, Misgurnus anguillicaudatus, Channa argus. 2. The attachment of giochidia of A. fukudai to the fish was found from December to February, while other mussels were in April. 3. The infectious rates of glochidia were 82%, 40% and 18% in M. anguillicaudatus, O. lapites and C. carassius respectively. The average rate of these 5 species was 26.9%. 4. The number of glochidia attached to each fish were 26, 13 and 8 individuals in C. argus, P. parva and M. anguillicaudatus respectively. And the average number was 4.9 individuals. 5. The attachment parts on the fish were 42.1%, 29.4% and 10.9% in pectoral fin, caudal fin and dorsal fin, and also on the base of pelvic and mouth part.

Authors have studied the size of eggs, the seasonal gonad changes, the spawning season and the demibranchs morphology of Lanceolaria acrorhyncha in the Lake Uiam. These researches were studied during the period from April 1983 to September 1984. The results of these investigations were summarized as follows; Mean diameter of the eggs was gradually increased from March (311 ㎛) to November and the mean diameter of maximum and minimum egg size was 282㎛ and 71㎛, respectively. The gonad in the female was filled with the connective tissue and the egg-sacs from March to November. The egg-sac was constricted after discharging of eggs and the connective tissue was gradually increased. The outer demibranchs of females served as marsupial(gravid) pouch. And the secondary water-tubes remain after discharging of the glochidia, and the central water-tubes served as ovisacs only in the primary water-tubes. The marsupial demibranchs lacked the divided system. The size of the marsupial demibranchs on the spawning seasons was increased three times.

In this paper, we implement the Digital Signal Processing System based on Human Machine Interface technology for the telematics with embedded noise-robust speech recognition engine and develop the communication system which can be applied to the automobile information center through the human-machine interface technology. Through the embedded speech recognition engine, we can develop the total DSP system based on Human Machine Interface for the telematics in order to test the total system and also the total telematics services. 자동차 텔레매틱스 용 음성 HMI(Human Machine Interface) 기술은 차량 내 음성정보기술 활용을 위하여 차량 잡음환경에 강인한 내장형 음성 기술을 통합한 음성 HMI 기반 텔레매틱스 용 DSP 시스템의 개발을 포함한다. 개발된 내장형 음성인식엔진을 바탕으로 통합 시험을 위한 자동차 텔레매틱스 용 DSP 시스템 구현 개발을 수행하는 본 논문은 자동차용 음성 HMI의 요소 기술을 통합하는 기술 개발로 자동차용 음성 HMI 기술 개발에 중심이 되는 연구이다.
