To facilitate estimation of the barbel size of a striped sea catfish, Plotosus lineatus Thumberg total length (TL) and head length (HL) against body weight (BW), HL against TL, and 1st maxillary barbel $(MxBL_1)$, 2nd maxillary barbel $(MxBL_2)$, 1st mandibular barbel $(MnBL_1)$ and 2nd mandibular barbel $(MnBL_2)$ against HL were regressed. The relationship of TL and HL for BW were described by the equation $TL=50.9373BW^{0.3072}\;(r^2=0.9898)$ and $HL=11.2938BW^{0.3144}(r^2=0.9572)$, respectively. The relationship of HL for TL was described by the linear equation $HL=0.1982TL+2.1996(r^2=0.9568)$. The relationship of each barbel for HL described by the equation of $HxBL_1=0.04420HL+0.3105(r^2=0.9615),\;MxBL_2=0.4592HL+0.5321(r^2=0.9519), MnBL_l=0.4057HL+1.9824 (r^2=0.9465)\;and\;MnBL_2=0.4355HL+1.8010(r^2=0.9429)$. Knowledge of the relative growth patterns about each barbel of this species is important for the propagation of seed as stock for large-scale striped sea catfish culture.

The purpose of this study was to investigate the differences in the method of patternmaking, difficult in draft of patternmaking, fit in sleeve, aesthetic view, fashionableness in the five types of two-piece sleeve under the controled situation. Five types of two piece sleeve that were originated from five countries including domestic companies which called A type, B type, C type, D type, and E type were used. In order to conduct the experiment fur the study, 10 persons who were well organized about the patternmaking drafted 5 types of sleeve and were tested for the differences in the method of patternmaking, difficulty in draft of patternmaking. Another panel were tested for fit in sleeve, aesthetic view, fashionableness in the five types of two-piece sleeve in jacket under the controled situation. The results of this study were as followed 1. C type was needed height of armhole in bodice and D type was needed height of armhole and width of armhole in bodice as well as all parts of sleeve measurements to draft patternmaking. 2. There were significant differences of the items such as cap height, ease amount around sleeve cap, width of sleeve, forwardness of sleeve and the length of elbow line of the five types patternmaking drafted. 3. There were significant differences of difficulty in draft of the five types of patternmaking. C type and E type were easier to draft. 4. There were significant differences in fitness of the sleeves in jacket. C type and E type were more fit. 5. There were significant differences in aesthetic view. A type, B type and E type were more aesthetic under the situation. 6. There were significant differences in fashionableness in jackets. A type and E type were more fashionable under the situation.

This study was conducted to obtain data for identification of species among elvers of anguillids, Anguilla japonica and A. anguilla and A. rostrata implanted in Korea for culture. The longer predorsal length and the fewer number of vertebrae distinguished elvers of A. rostracta from those of A. anguilla and A. japonica. A. japonica and A. anguilla were well discriminated each other in the statistical value of preanal length which the former showed shorter distance. It was remarked phylogenetically that the morphological changes according to growth in head and predorsal length of A. rostrata was different from other two species. So the elvers of A. japonica, A. anguilla and A. rostrata culturing in Korea can be distinguished by the vertebral counts, predorsal and preanal length.

A total of 15 larvae [3.53~19.49 mm standard length (SL)] belonging to the family Bothidae collected from the southern sea of Korea in 2016 were identified as Psettina tosana based on 434 base-pair sequences of mitochondrial DNA cytochrome c oxidase subunit I. Larvae of Psettina tosana have anterior-most two elongated dorsal fin rays. Uniserial melanophores present on the dorsal and anal fin base, whereas melanophores on the body absent. An inflection point in the relative growth of head length and head depth against SL was shown between 9.93 mm and 10.73 mm SL. The examined larvae of Psettina tosana are clearly distinguished from the most similar species, Psettina iijimae in having no melanophore patches in the proximity of dorsal and anal fin base.

Head length, snout length, postorbital length, and eye diameter were measured in 209 brown croaker, Miichthys miiuy, ranging from 3.0 to 650.0 mm in total length (TL). All of the four head dimensions were regressed against the TL respectively and were increased linearly with the relative size of the head. The determination coefficients ($r^2$) ranged from 0.9823 to 0.9916, and all analysis of variance values were significant (P<0.0001). Those results suggest that these head dimensions may be useful indicators for detecting morphological deformities or for individual and population growth histories to aid in the successful rearing of brown croaker fingerlings.

Soybean was originated from the regions of Manchuria where it was processed into Dujang, the fermented soybean souce. It was not until the Han dynasty in China that 'Shi', one type of Dujang, was introduced. 'Shi', which is also known as 'Sanguk'(loose soybean Meju), is made by first boiling and then fermenting the kernel of cooked soybean. It was admitted by the Chinese scholors that the 'Shi' which was used in China was introduced from Manchurian, the neighboring people to China at that time and the concestor of Korean. 'Maljang' is a form of caked-shaped 'Meju' which is made by formenting cooked and mashed soybean. The 'Maljang' of Manchuria was introduced to China, where it was called 'Maldo'. This fact is stated in a book, 'Saminwolyong', written during the 2nd century. 'Maljang' is presently used in Korea, but China has abandoned the use of 'Maljang' since the 6th century. It was introduced to Japan from Korea around the 7th century, and is remained in a few local regions. Although the term 'Jang' is representing all sort of fermented soybean preducts, including 'Shi' and 'Maljang', today, the definition of 'Jang' differs between China and Korea. According to the Chinese definition of 'Jang'. it is fermented soybean mixed with other cereal Koji. 'Jang' was first mentioned in 'Jaeminyo sool' in China and it was lator introduced to Japan However, in Korea, the Chinese type of 'Jang' was not commonly used due to the popularity of 'Maljang'.

A single specimen of the ophichthid Muraenichthys gymnopterus (254.6 mm TL) was collected from the middle Yellow Sea off Incheon, Korea. It represents the first record of the species, the genus, and the subfamily from Korea. This species is characterized by the following combination of characters: a constricted midlateral gill opening; dorsal fin origin before anus, closer to the anus than to the gill opening; blunt teeth, jaw teeth in bands, and multiserial dentition; third preopercular pore present; single infraorbital pore between anterior and posterior nostrils; brownish colour; depth and width of gill opening 43.2 times and 33.7~65.3 times in total length, respectively; eye diameter 15.0~31.0 times in head length and total vertebrae 154~161. New Korean names are proposed, "Gaet-mul-baem-a-gwa" for the subfamily Myrophinae, "Gaet-mul-baem-sok" for the genus Muraenichthys, and "Gaet-mul-baem" for M. gymnopterus.

A closely associated set of characteristics was analyzed using both classical and truss dimensions to discriminate the morphometric traits of three species of torrent catfish (Amblycipitidae) in Korea. After arcsine square root transformation, 18 measurements relative to the standard length and three measurements relative to the head length of each species of torrent catfish were compared statistically. Classical and truss dimensions of each of four morphometric traits showed higher values in the bullhead torrent catfish, Liobagrus obesus, than the Korean and south torrent catfish (L. andersoni and L. mediadiposalisa, respectively; P<0.05). Truss dimensions of three morphometric traits were higher in the bullhead and Korean torrent catfish than in the south torrent catfish (P<0.05). There were no significant differences in six morphometric traits among these Amblycipitidae. The dimensions used in this study may be useful as taxonomic indicators to discriminate species of Liobagrus in Korea.

Soil microfungi of the paddy fields in Korea were isolated by the dilution plate method from soil samples of two selected sites. It was concluded that 14 species among 30 species identified were undescribed fungi in Korea. Among them, 7 species of Ascomycetous fungi were described in this paper as new to Korea. Species of the genus Talaromyces were found to be dominant in paddy field soils and they consisted of Talaromyces flavus var. flavus, T. panasenroi, T.stipitalus and T.trachyspermus. Special attention was paid on the predominant occurrance of Westerdyrella multispora which produced globose to subglobose pseudothecia containing 32 spored asci with multiseptate, cylindrical ascospores. A cellulose decomposing ascomycete, Chaetomium globosum, was also found which produce black, ostiolate perithecia furnished with numerous, wavy to undulate terminal hairs. They contain evansecent, clubshaped, 8 spored asci with lemon-shaped, olive brown ascospores. Another ascomycte, Emericellopsis terricola with Acremonium anamorph, waas isolated from two sites.

Steel wires are made by elongating hot billets. If the billets have internal or surface defects, the wire can be broken during elongation process. After testing surface defect, we are testing internal defect by ultrasonic transducers. POSCO is producing two kinds of billets, hot rolled billet and cast billet. Hot rolled one is denser than cast billet. Because of the low density and rough surface, ultrasonic testing is difficult for the cast billet. Size of the transducer was related with the size and density of the billet. A transducer having 21mm long, 8.5mm wide and 0.95mm thick piezoelectric ceramic plate was best for $160mm\;{\times}\;160mm$ cast billet. Center frequency of the transducer was 2.25MHz and the focus distance was 70mm.
