1980년 12월부터 1981년 7월까지와 1982년 2월부터 7∼8월까지 西海沿岸에서 베도라치類 稚魚資源을 조사한 결과 출현한 치어 가운데 Enedriasnebulosus의 稚魚出現 可能性을 배제할 수 없으나 대부분은 Enedrias fangi의 치어일 것으로 판단된다. 치어의 分布는 12월부터 시작되며 外海쪽보다는 沿岸에서 더 많이 分布했고, 2月 경우 於靑島 부근에서 가장 높은 분포를 보였다. 産卵은 12월부터 3월 사이에 행해지는 것으로 판단되며 치어의 월별·정점별 출현분포를 참고할 때 於靑島 부근과 加露林灣 外海쪽이 주 산란장으로 추정된다. 産卵은 滿 1年生부터 시작하여 평균 抱卵數는 918卵였다. 산란된 치어는 海況이 안정되고 먹이가 풍부한 內灣으로 回游하며 6∼7월에는 다시 外海의 成長棲息場으로 回游한다. 또 산란후 약 2個月이면 浮游幼生期를 마치고 表層에서 底層으로 이동한다. 稚魚期의 月別成長은 장기전에 걸친 産卵習性으로 정확한 월평균 성장률을 파악하기 힘들었으나 약 9mm정도일 것으로 思料된다. 한편 치어기로부터 未成魚期까지의 體長과 體重의 關係式은 W=1.67×10?L??(r=0.966)로 나타났다. 胃內客物 조사결과 稚魚期의 主된 먹이생물은 copepoda이며 decapoda와 cirripedia의 幼生, mysidacea, 卵稚魚 등도 중요한 먹이 생물로 이용되고 있다. 산란후 성장함에 따라 먹이 選好度는 넓어지며 成魚가 되면 amphipoda와 polychaeta가 主된 먹이 생물로 이용되고 있다. 서해연안에서의 베도라치類 稚魚의 資源量은 約 4∼5년 올 週期로 絶頂이 形成되는 것으로 추정된다. 이러한 年間漁獲變動은 단위 노력당 어획량의 자료 외에도 海況, 捕食者-被捕食者의 관계, 도는 生物學的 週期 等에 대한 구체적인 자운조사로 解析이 가능할 것이다. The gunnel larvae stock in the west coast of Korea was investigated on the taxonmical position, distribution, spawning, migration, growth, feeding habit and stock strucure. Though two species of Enedrias(E.nebulosus and E. fangi) distribute in the Yellow sea, the majority of the larvae which occurred during the study periods (Dec., 1980-July, 1981, and Feb.-Aug., 1982) seems to be fangi. Spawning takes place in December-March, and .the major spawning grounds seem to be near Eochung Island and at offsea of Garolim Bay. The fish begin to spawn from one-year-old group, and the average fecundity of this group is ca. 918 eggs with 0.72mm egg diameter in average. The larvae after hatching out begin to migrate into the nursing grounds at the coast or inner bay, and then migrate back toward the outbay. This migratory mechanism seems to be feeding and adult migration. The monthly growth rate during the larval stage seems to be ca. 9mm. Concerning the feeding habit of ,the larvae, copepod is the most important food organism. However, during the adult stage, polychaete and amphipod are major food organisms. The larvae of decapod and cirriped, mysid and fish eggs also occurred frequently in the stomach of the larvae.

In this paper, we perform the recognition test for Korean 100 monosyllabes using RPNN(recurrent prediction neural networks). The RPNN is trained to nonlinear predictor, accoding to time variation of speech pattern, is not use time sequential algorithm. In recognition experiment we got the recognition rate 69.0%, 72.30% and 71.20% using RTRL(real-time recurrent learning) training algorithm when the predition order is 2, 3 and 4.

The exsiting CHMM is hard to express time-transient-variation. To solve such problem, we proposed a new method that is the hybrid network of the feed-forward networks and the HMM. The network is trained to predict the feature vector, varies in each time, is used instead of the mean vector in the HMM, Hence the dynamic feature of speech pattern is provided for the HMM. At the experiment, we compared the result of CHMM+MCEP, CHMM+MIX with NNPHMM. At the result, we got the recognition rates of 73.8% for NNPHMM.

Post radical mastectomy reconstruction using a transverse rectus abdominis myocutaneous flap involves certain problems at the donor site as the difficulty in closure secondary to excessive tension and the development of a postsurgical abdominal hernia. The usage of alloplastic materials such as Marlex may also cause eventual weakness as well as a foreign body reaction. While autogenous tissues may be used for a remote myocutaneous flap transposition or a free-tissue transfer, the problems such as a donor site defect, atrophy secondary to denervation, etc. exist. To avert these problems, we propose to use the autogenous tissue in a manner that provides a dynamic support in addition to the functional reconstruction. The components separation method decribed here separates the muscle groups of the abdominal wall, and allows several advantages over treating the abdominal wall as a single unit. One of the advantages is the increased mobility of individual muscles. The allows transferance of the flap over a greater distance which in turn reduces excessive tension and makes closure of the donor site defect easier. Thus, this procedure provides a dynamic support and reduces the incidence of hernia. We experienced 3 cases of abdominal wall reconstruction after TRAM flap transfer(one case after bilateral TRAM flap, two cases after contralateral unilateral TRAM flap) using external oblique muscle sharing or rectus sharing. So we present clinical cases of the abdominal wall reconstruction after TRAM flap transfer with a review of the literature.

In this paper, we compose neural predictive HMM(NNPHMM) to provide the dynamic feature of the speech pattern for the HMM. The NNPHMM is the hybrid network of neural network and the HMM. The NNPHMM trained to predict the future vector, varies each time. It is used instead of the mean vector in the HMM. In the experiment, we compared the recognition abilities of the one hundred Korean syllables according to the variation of state number and prediction order. The state number of the NNPHMM increased from 4 to 6. And the prediction orders increased from 2nd to 4th order. The NNPHMM in the experiment is composed of multi-layer perceptron with one hidden layer and CMHMM. As a result of the experiment, the average recognition rates are 85.2%, 85.6% and 85.5% when the state number is 5, the prediction order is the 2nd, 3rd, 4th, and the hidden layer is 10 dimensions, respectively.

This paper is a study on the composition of Real-Time Continuous Speech Recognition System for Man-Machine Interface and it examines the posibility that applies to automatic system. The Continous Speech Recognition System is composed of Contivuous Distribution HMM model and algorithm of One Pass DP method. The System is composed so that it may detect start point and end point of speech data which are converted into samples by 10 KHz, 8 bit A/D whthin real time, then so that it may recognie them by one Pass DP method, display the result of recognition on PC monitor and at same time sent control data to Interface. HMM models are creadted by training for continuous speech samples which are control words, area names and digital sounds. In the result of experiment by Continuous Speech Recognition System, there are some kind of errors which are insertion, replacement and deletion of one syllable, but it examined the posibility that can by applied to Man-Machine Interface on automatic system if post-process is performed for recognition.

This paper documented mophological changes of embryonic development and first zoea larvae of snow crab, Chionoecetes opilio. Female crabs were sampled by the Danish seine fishery at the depth about 200m in Sep. 1997 in the eastern coast of Korea. Female with newly berried eggs was reared at the water temperature of 5℃ till the time of hatching. The results obtained are as follows. Embryonic development : According to morphogenesis of fertilized eggs, the developmental process of the embryo was classified into the following seven stages : First stage (cleavage and blastula stage, 24 days) Second stage (gastrula stage, 72 days) Third stage (nauplius stage, 22 days) Fourth stage (metanauplius stage, 57 days) Fifth stage (stage of a pigmentary deposit in the compound eye, 30 days) Sixth stage (chromatophore appearance stage in maxillipede, 56 days) Seventh stage (hatching stage, 36 days) Larvae hatched as prezoeas and they molted to first zoea in about an hour. The first zoea is 4.6 to 5.1 ㎜ in length, 3.2∼3.6 ㎜ in width. The abdomen consists of five segments and a bifurcate telson.
