  • Matured adults of chum salmon were collected from Namdae-chun River, Yangyand-gun, Kangwon-do, Korea in december of 1989 and 1990. Artificial insemination was made in the field. Hatching and neasing were cassied out in laboratories of the Yangyand Fisheries Institute and Korea Ocean Research and Development Institute : Ossification of bones of alevin, fry and smolt were investigated : 1. The newly hatched alevins, 1.80 to 2.56mm in total length, were ossified partly on parasphenoid, maxillary, dentary and opercle bones. 2. The alevin stage, the visceral bones connected with feeding and respiratory function were ossified earlier than cranium and vertebra. At swim up stage, the fry attained 3 to 4cm in total length, most of bones except cranium were ossified. 3. Teeth on the jaw bones, palatine, vomer, upper and lower pharyngeal bones were increased conspicuously when the body length were ranged from 3 to 4cm. 4. Caudal fin of hatched larvae had already seventeen occified rays and developed earlier than any other fins.

  • Infectious Pancreatic Necrosis Virus (IPNV) is one of the most important pathogens for inland fish farming and had been first reported in Korea from returning adult chum salmon (Oncorhynchus keta) at hatcheries on the east coast. During the past years, several viruses identified as IPNV were isolated not only from chum salmon, but also from gold fish (Carassius auratus), eel(Anguilla japonica), and rainbow trout (Salmo gairdneri). An isolate, coded DRT, from fingerlings of pan-cultured rainbow trout in Daechung Dam showed different serotype from three known reference serogroups of IPNV such as VR-299, Sp, and Ab. Antisera to three of these serotypes, however, partially neutralized the infectivity of this isolate. Anti-Sp type was rather effective than either anti-VR-299 or anti-Ab, implying DRT could be more closely related to Sp. DRT has been purified and its RNA genome segments were compated showing that the isolate does not belong to any of known serogroups even with some common antigenicity.

  • The complete sequences of mtDNA control regions of six salmonines were determined: 1089 bp in lenok (Brachymystax lenok); 999 bp in cherry salmon (Oncorhynchus masou masou) and Ishikawa's cherry salmon (O. masou ishikauiae); 1002 bp in chum salmon (O. keta), and 1003 bp in rainbow trout (O. mykiss) and an albino mutant of rainbow trout. The estimated interspecific sequence divergences from PCR/direct sequencing data ranged from 5.42% to 16.49%. The organization of this region is similar to that of other vertebrates. A 81 bp tandemly repeated sequence, associated with length variation was observed in the 3' end of the salmonids control region in this study. In addition, The phylogenetic tree based on the control region sequences supported that cherry salmon was closer to chum salmon than to rainbow trout, while lenok was most distantly related species among six salmonines.

  • We carried out immunoblot analyses to study expression and subcellular distribution of the N-methyl-D-aspartate receptor(NR) subunits in salmon (Chum Salmon, Oncorhynchus keta). We prepared subcellular fractions such as brain homogenates, synaptosomes, and postsynaptic density (PSD) from salmon brains, and analyzed protein compositions by SDS-polyacrylamide gel electrophoresis (SDS-PAGE). In a Coomassie-stained 6% SDS-gel, about 20 distinct major protein bands could be identified in the PSD fraction. Immunoblot analyses using antibodies against rat NR subunit 2A and 2B antigens (NR2A and NR2B, respectively) showed weak but evident signals at the 180 kDa positions in the salmon PSD fractions. However, in contrast to rat NRs, the salmon NR2A and NR2B are not recognized by a phosphotyrosine-specific antibody suggesting that the salmon NRs are regulated differently from those of the rat by protein tyrosine kinases. Our results indicate that NR2A and NR2B subunits are expressed in the salmon PSD fraction but not regulated by tyrosine phosphorylation.

  • This study compared the food quality of salmonid fishes according to the species, country of origin, and separated part, such as fillet and frame. The proximate composition of chum salmon from Norway (CS-N) was 74.4% moisture, 19.5% crude protein, 4.2% crude lipid, and 1.2% ash. These values were within roughly 1% for the other salmon species. There was no significant difference (at P<0.05) in the Hunter a value of salmon muscle according to sepatated parts. However, there was a significant difference (P<0.05) in Hunter a value of salmon muscle according to the species and country of origin. There were significant differences in odor intensity and hardness of the salmon according to the species. The major free amino acid in all of the salmon muscles was anserine, which ranged from 61.3 to 73.0%. The taste value was the highest for salmon imported from Alaska (CS-A), followed by pink salmon, CS-N, and muscle separated from the frame (AS-C). In the taste value of all salmon muscles, the major amino acid was glutamic acid. The total amino acid content of salmon muscles ranged from 18.36 to 19.64 g/100 g, and the major amino acids were glutamic acid and aspartic acid. There were differences in the mineral contents, including Ca, P, K, and Fe, and fatty acid composition of salmon muscle according to species.

  • In this study, a process of re-creating Jindo Buk Chum, one of the traditional Korean arts, into digital art using various artificial intelligence technologies was proposed. The audience's emotional data, quantified through artificial intelligence language analysis technology, intervenes in various object forms in the projection mapping performance and affects the big story without changing it. If most interactive arts express communication between the performer and the video, this performance becomes a new type of responsive performance that allows the audience to directly communicate with the work, centering on artificial intelligence emotion analysis technology. This starts with 'Chuimsae', a performance that is common only in Korean traditional art, where the audience directly or indirectly intervenes and influences the performance. Based on the emotional information contained in the performer's 'prologue', it is combined with the audience's emotional information and converted into the form of images and particles used in the performance to indirectly participate and change the performance.

  • The purpose of this article is to understand the characteristics and meanings of the Hwanghae-do Gutchum, or shamanic ritual dance. First, the characteristics of the Hwanghae-do Gutchum are summarized as follows. The regular dances that appear in all pieces of Gutgeori or the tune of Gut of the Hwanghae-do Gutchum feature Geosangchum, followed by domu and heojeonmu in the sequential order. The accompaniment rhythms are Geosang rhythm, Chum rhythm, and Yeonpung rhythm. The dance featuring mugu, or shaman implements held on shaman's hand as part of the Hwanghae-do Gutchum, which symbolizes the characteristics of deities, is the same as domu aligned with the dance rhythm and the whirling dance aligned with the Yeonpung rhythm. The name of mugu, mubok (shaman clothing) and/or deities may be used as the name of Gutchum but there is no originality of Gutchum. The Beokgu Chum and Samhyeon Chum as part of the Hwanghae-do Gutchum use Beockgu Jangdan and Samhyeon Jangdan, which deserves to have their originality acknowledged. Hwanghae-do Gutchum is closely related to the rhythm. The harmony of janggu player and a female shaman is essential in practicing the Hwanghae-do Gut. If a janggu player fails to perform to properly support the gut practice of a female shaman, the shaman is not able to proceed with a smooth practice and causes confusion. On the other hand, if the gut performance of a female shaman fails to catch up with the performance of janggu, the gut becomes plain and simple at best. Janggu is the single most important element that determines the success or failure of the Hwanghae-do Gutchum. A female shaman takes the harmony and collaboration with a janggu player so seriously that she is willing to reschedule the practice of gut if its schedule does not match that of the janggu player. The Hwanghae-do Gutchum is largely dependent on gyeolrye. However, the difference between the chum and the rhythm caused by gyeolrye has disappeared due to the intangible cultural assets. That is, designating an intangible cultural asset has resulted in eliminating all distinctive characteristics of Hwanghae-do Gutchum. With the distinction of gyeolrye becoming vague, they have lost interest in the genealogy of gut they have learned. It is no longer gyeolrye but the intangible cultural property system that serves as an important factor to distinguish chums.

  • Dr. Lawrence H Jones developed innovative approach for the treatment of neuromuscular and musculo-skeletal disorders such as fibromyalgia, myofacial pain syndrome, any other muscle pain. This technique is called Strain/Counterstrain technique which uses effect of neuromuscular reflex for treatment of strain. First, Relieving spinal or other joint pain by passively putting the joint into its position of greatest comfort; secondly relieving pain by reduction and arrest of the continuing inappropriate proprioceptor activity. This was accomplished by markedly shortening the muscle that contains the malfunctioning muscle spindle by applying. mild strain to its antagonists. In other words, the inappropriate strain reflex is inhibited by application of counterstrain. Many other techniques have been developed for treating of muscle pain due to somatic dysfunction, but we want to introduce you to strain/counterstrain technique because this is basic concept and theory of Chum therapy for controling motor system.
