  • Several studies using Convolutional Neural Network (CNN) have been conducted to detect and classify the sounds of marine mammals in underwater acoustic data collected through passive acoustic monitoring. In this study, the possibility of automatic classification of bearded seal sounds was confirmed using a CNN model based on the underwater acoustic spectrogram images collected from August 2017 to August 2018 in East Siberian Sea. When only the clear seal sound was used as training dataset, overfitting due to memorization was occurred. By evaluating the entire training data by replacing some training data with data containing noise, it was confirmed that overfitting was prevented as the model was generalized more than before with accuracy (0.9743), precision (0.9783), recall (0.9520). As a result, the performance of the classification model for bearded seals signal has improved when the noise was included in the training data.

  • This study performs statistical analysis through a questionnaire in order to examine effects of shapes of beards on a formation of male image in male/female workers in their 30s-40s. The findings suggest that sensitive image response factor depending on the shapes of beards functions as an important one in the modifications of attraction, character and image. Although there is a difference between male and female, in the preference for beards' shapes effective in the change of image, no difference is found in sensitive responses of them according to quantities of beards. This study has an implication for quantifying sensitive responses to the formation effect of male image depending on the shapes of them. It provides a guideline for total image making to males who want to change their external image formation according to shape changes of beards in the future, and is simultaneously expected to be used as basic and applied materials in the beauty industry for males.

  • In the 17th century, men's hair style showed a dramatical change to thick hair style with femineity. During the 17th century, men wore their hair longer than at any other time in the history of western culture. Men's hairs in the early 17th century were defined as short hair style influenced by ruff collar of renaissance and thick beards and moustaches During the mid 17th century, shoulder-length hair style was predominant over all classes. As hair style became long, beards and moustaches gradually declined in favour: from 1625, small neat beards, and moustaches turned up at the ends, got progressively smaller, and by 1650 the beard was only small tuft on the chin, disappearing completely by 1680. In the late 17th century, very long, thick and shiny hair got a great popularity with the gorgeous and decorative baroque costume dominated over the entire Europe. The habit of adding false hair when natural hair was deficient led to the introduction of the periwig, which became an essential part of a fashionable man's attire. Wiggery were widely used to express curled and puffed hairs more exaggerated. As the long hair style with wiggery became popular, various style of beard and moustache got smallar so that they were ended up in entire disappearance in the end of the 17th century.

  • To investigate antitumor constituents of Hydnum repandum, which belongs to edible basidiomycetes, the mycelia separated from the carpophore were shake-cultured and subjected to hot water extraction. The extract was concentrated under vacuum and mixed with a three-fold volume of 95% ethanol to yield precipitates. The water soluble fraction of the precipitates was dialyzed and then lyophilized to yield a water soluble protein-polysaccharide fraction (= WPPF). This exerted antitumor activity against sarcoma 180 implanted in ICR mice. When administered i.p. at the dose level of 20mg/kg once daily for ten consecutive days, it showed an inhibition ratio of 54.3%. WPPF was found to be composed of a polysaccharide moiety (42% of WPPF) and a protein moiety (28% of WPPF) when determined by colorimetric method using anthrone reagent and Folin's phenol reagent. The polysaccharide moiety of WPPF was found to contain glucose (57.4%), mannose(19.3%), galactose (10.8%), xylose (6.8%), and fucose (5.7%), when the methanolysate of WPPF was analysed by GLC method.

  • Studies were carried out to describe the structure and distribution of various sensilla on the antenna and mouthparts of the Oriental tobacco bud worm (H. assulta) larvae by light and scanning electron microscopy. The larval antenna has 3 segments. The second segment has 2 hairs and 3 pegs, while the third segment shows 3 regular pegs and a segmented peg (styloconicum type). Each mandible bears 2 aporous hairs on the lateral surface. The labrum bears 12 aporous hairs on its external surface. and 6 aporous hairs, 4 coeloconica-like sensilla and 2 campaniformia-like sensilla on its epipharynx. The stipes has 3 hairs, and the galea has 3 pegs. 2 papillae and 2 domes. The maxillary palpus has only a digitiform sensillum on its 1st segment but 11 sensilla of 4 different types on its 2nd segment. Maxillary sensilla represent almost 70% of total number of larval sensilla on the mouthparts. Labial pal pus has a single segment bearing a large segmented uniporous peg and a small peg. Finally their possible fun¬ctions were suggested.

  • This study was conducted to determine the injury type and frequency of bearded dragons during single and group breeding according to stocking density, for 16 weeks. A total of 14 bearded dragons compromising three groups were selected for this study. Six and four bearded dragons bred in a cage of 45 cm × 45 cm × 45 cm were designed as group A and B, respectively. Group C was made of four partitions (20 cm × 20 cm × 20 cm) of equal size in the kennel, and the dragons, four in number, were reared alone. Injury type criteria were given 1 score each in 6 stages. Most of the injury types in group A were primary tail cutting, which was 1 point, depending on the score, except for 4 scores. The injury type of group A varied, that is 1, 2, 3, and 5 scores, and the pattern lasted for 2 to 9 weeks. After 10 weeks, the dragons showed no response to injury type, except 4 scores at 11 weeks and 2 scores at 14 weeks with a frequency of one, respectively. The representative injury types of the group B were primary tail cutting, which was 1 point, and the scores of the injury type from 2 to 11 weeks were the highest; the frequency of occurrence at 1 and 2 scores was 5 times and 3 times, respectively, and the frequency of occurrence at 3 scores was twice. In addition, 5 scores were found to have the lowest frequency of occurrence. Solitary breeding showed no response to the type of injury for 16 weeks. Consequently, single breeding with an appropriate stocking density did not affect stress, and it could be expected a positive aspect for pet welfare.

  • The larvae and juvenile development of haddock Melanogrammus aeglefinus which is significant commercial fish living north Atlantic Ocean are described here. Larvae were reared in laboratory and sampled periodically for developmental study until 67 days after hatching. An increase in total length(TL) of fish indicated continuous growth, described by the growth expression Y=4.07 $e^{0.037}$( $R^{2}$=0.9978). The newly hatched pre-larvae was 4.9 mm in TL with ellipsoid yolk. In 16 days after hatching, larvae attained 6.8 mm in TL, and absorbed the yolk completely to become post-larval stage, but first heterotrophic food could be in 7 days after hatching already. Post-larval stage continued during 16~52 days after hatching with development of organs attachment. In 61 days after hatching with 41.3 mm in TL, the fries became a juvenile stage respectively having small teed lateral line, and a black blotch on the flank same as adults, but chin barbel was not developed yet. It was presumed that haddock changed food and ecological behavior after metamorphosis ken this time.e.

  • While an investigation on the old samples kept at collection room in National Institute of Fisheries Science (NIFS), we found a unique single specimen of burbot, Lota lota (54.7 cm in standard length) from Amnokgang River, North Korea on 14 April 1935. Burbot is the only stream dweller among members of the Gadiformes and found in the northern parts of Eurasia and North America. There was a little information in Korea, because it inhabits only the northern part of North Korea. This species is easily distinguished by having two dorsal fins, one anal fin, a barbel, and posterior of caudal fin rounded. This study provides detailed morphological characteristics and compares it with those of previous literatures on the North Korean L. lota.

  • In this study, the anatomic characteristics and the contents of nutritional ingredients and minerals of silky fowl and yeonsan ogolgye was investigated. Silky fowl is covered with white silky feather. There is a pinch of vertical white tassel on peak of the head, especially a silky fowl cock. The crown of a silky fowl has a nickname of phoenix crown, the crown of a cock is mostly like a rose, while that of a hen like strawberry or mulberry. The ear of silky fowl is mostly peacock green(Light blue turquoise), bronze for a small part. Peacock green is most common for Silky Fowl with a age of $60{\sim}150$ days, over the age of 150 days, the peacock green will be gradually replaced by purplish red. Beaks are leaden blue, short and stout while the face is smooth and fine. The lower jaw of silky fowl has comparatively long tiny hair, similar to beard. The two legs of silky fowl are covered with a handful of feather, or known as 'Putting on trousers'. Each leg of silky fowl has five talons. The whole skin, eyes, mouth, talons of silky fowl are grey black The bone and marrow of silky fowl are light black the periosteum is black. The whole meat, internal organs and abdominal fat of sillry fowl aye black the heart and leg meat are light black. Silky fowl meat had lower moisture and lipids content, but higher Ash and protein content than meats of yeosan ogolgye and general chickens. For mineral contents of leg muscle and breast muscle, silky fowl had higher contents of phosphorus (P), iron (Fe), potassium (K), zinc (Zn) than those of yeonsan ogolgye, while yeonsan ogolgye had higher contents of calcium (Ca) than that of silky fowl. The contents of iron (Fe) and zinc (Zn) is higher in leg muscle than in breast muscle for the silky fowl and yeonsan ogolgye. Leg muscle of silky fowl contains a lot of iron (Fe), about 4 times as much as that of leg muscle of yeonsan ogolgye. For the silky fowl and the yeonsan ogolgye, leg muscles contains a lot of zinc (Zn), about 5 times, 4 times respectively as much as that of breast muscle.

  • Embryonic and larval developments on Pacific cod, Gadus macrocephalus are described from laboratory-reared specimens. The eggs (1.075~1.168 mm in diameter) were weakly adhesive, almost spherical in shape, transparent and unpigmented, showing a pale yellow yolk without oil globules. Hatching was occurred 220 hrs after fertilization at $9.8^{\circ}C$. The newly hatched larvae (3.72~4.40 mm in total length, TL) had 43~47 (11~13+32~34) myomeres, mouth and anus which was not yet opened. The yolk was completely absorbed at 4.58 mm TL, and transformed to postlarval stage. Locations of the anus and second dorsal fin origin, and distinctive growth of the larvae head were observed at 5.48 mm TL with melanophores in the gill cover and upper region of the occipital. In addition, melanophores were distinctive in the ventral region and caudal fin base at 6.88 mm TL. All fins were formed with a complete set of fin rays having the following counts (D. 3~7-12~14-13~14; A. 13-15) at 11.54 mm TL. Both lateral line and barbel of lower jaw were observed at 15.07 mm TL.
