This study is to inquire into the publishing situation and developmental plans of korean magazine of Joseon people (Korean) in China, About twenty types of magazines for Joseon people(Korean) in China have been published since the liberation of China. These magazines have mainly brought changes such as publication suspensions, reissuing, and renaming in reflection of reading classes and political influence. Also, when classified by topic, the mainstream includes magazines of political. cultural, and art fields. On one hand, difficulties in magazine publication come from a decrease in the Korean Chinese population, population movements, support reduction and abolition from the Chinese government and increases in material costs. To overcome this, Korean reading classes should be secured and a magazine composed in two languages(Chinese-Korean) should be published to pioneer active cultural exchange in and out of China, and various forms of support should be devised from Korea.

This study analyzes the structure types of salmon oil to evaluate the purity of salmon oil products based on the 38 different types of imported salmon oil products distributed in the Republic of Korea. The major types of omega-3 foods in the salmon oil are ethyl ester (EE) and triglyceride (TG). If the salmon oil contained potential contaminants and was processed in order to remove it, EE type omega-3 fatty acids are found in concentration. This provides a good guide in assessing if products were made with EE type ingredients or re-esterified contaminated materials. The results of the FT-IR analysis showed significant difference in the C=O, C-O band positions in TG and EE. There were 19 TG type products and 19 EE type products. The analysis of carbon isotope ratio was performed on the types of TG and EE. There were different properties in the 19 TG type products. In one product, the carbon isotope ratio was -25.15 and the other 18 products showed -22.15~-23.96. The carbon isotope ratio of all 19 EE type products showed -21.91~-23.74. The results of the TLC analysis showed similar results with FR-IR. The re-esterified TG form was not detected in the TG type products, confirming that the TG type products contained natural salmon oil. This study aimed to provide the basic material in classifying the types of natural salmon oil and re-esterified salmon oil, by analyzing the pattern and proportion of FT-IR spectrum, carbon isotope ratio, and TLC.

CHSE(Chinook Salmon Embryo)-214 fish cell lines was cultured in Eagle's minimal medium (MEM) supplemented with 10% fetal bovine serum and 2mM-glutamin. Optimum growth temperature of CHSE-214 cell line was $20^{\circ}C$. Infectious pancreatic necrosis virus(IPNV) was successfuly multiplied and showed the cytopathic effect in CHSE-214 cell line. Infection symptom of IPNV was observed with inverted phase contrast microscopy. At 6h-12hrs post-infection, the cells infected with IPNV were similer to normal cells. At 18-24hrs post-infection, the cells were somewhat round form and a little swollen form than normal cells. At 30hs post-infection, the cells were becoming more abnormal cells. At 48-68 post-infection, the infected cells were lysed and showed the severe cytopathic effect.

This study was conducted to improve yield and functional properties of autoclave-treated salmon frame extracts (SFETA) using commercial enzymes (Alcalase 2.4 L FG, Flavourzyme 500 MG, Neutrase 0.8 L and Protamex 1.5 MG). Yield and angiotensin I converting enzyme (ACE) inhibitory activity of all enzymatic hydrolysates improved compared to those of control (undigested extracts), which were the highest in hydrolysates incubated with Protamex 1.5 MG for 4 hrs (P4-treated hydrolysates) and 2 hrs (P2-treated hydrolysates), respectively. However, antioxidant activities of all enzymatic hydrolysates showed less than 29%. According to the trichloroacetic acid soluble-N, volatile component intensity and sensory evaluation, when compared to control, taste of P4-treated hydrolysates improved, while its fish odor strongly smelt. Therefore, for efficient use of P4-hydrolysates, the fish odor should be improved by Maillard reaction of extracts or pre-treatment of salmon frame.

This study aimed amount optimization of salmon Oncorhynchus keta mince (SM), threadfin bream Nemipterus virgatus surimi (TBS), natural tomato (NTC) and paprika colorants (PC) for preparation of fish cake using molding device and response surface methodology (RSM). The results of the RSM program for processing of fish cake indicated that the amount optimization of independent variables based on the dependent variables (Y₁, gel strength; Y₂, overall acceptance) for high-quality FC were 263.8 g for SM, 88.5 g for TBS, 0.11 g for NTC and 0.20 g for PC. Hunter redness and overall acceptance of fish (salmon) cake, which was prepared under the optimum amounts, were 13.82 and 8.33 score, respectively. The fish (salmon) cake was superior in sensory overall acceptance to commercial fish cake.

Competition in the modern CPU market has shifted from speeding up the clock speed of a single core to increasing the number of cores. As such, there is a growing interest in parallel programming to maximize the use of resources of many core processors. In this paper, we propose parallel programming models in Haskell to find an advisable parallel programming model for many-core environments. Specifically, we used Eval monad and Cloud Haskell to develop two versions of parallel programs: plagiarism detection and K-means. Then, we evaluated the performance of the developed programs in 32-core and 120-core environments. The results of our experiment show that the Eval monad is highly efficient in an environment with a small number of cores. On the other hand, the Cloud Haskell runtime shows 37% improvement over Eval monad and the scalability shows a 134% improvement over Eval monad as the number of cores increases.

This study was conducted to evaluate fish cake made from salmon Oncorhynchus keta frame muscle (FC-SFM) in terms of taste, flavor, and nutritional characteristics. FC-SFM was significantly higher in moisture and lower in ash and carbohydrate than commercial fish cake (CFC). There were no significant differences in protein and lipid contents between FC-SFM and CFC (P<0.05). The total amino acid content of FC-SFM was higher than that of CFC. The major amino acids found in FC-SFM were aspartic acid and glutamic acid. The mineral content based on 100 g of FC-SFM was 76.7 mg calcium, 126.3 mg phosphorus, 19.1 mg magnesium, and 88.7 mg potassium. The total fatty acid content of FC-SFM was 1,833 mg/100 g, which was lower than that of CFC. The major fatty acids found in FC-SFM were 16:0, 18:1n-9, and 18:2n-6. The eicosapentaenoic acid and docosahexaenoic acid content of FC-SFM was higher than that of CFC. The results suggest that FC-SFM has different nutritional characteristics to CFC, and FC-SFM could be commercialized.

Seven specimens of salmon(Oncorhynchus keta) purchased directly, in Oct. 10. 1990, in the Taep'o port. Kang-won-do were examined for infection state of anisakid larvae and classification of extracted larvae according to morphological characters. The results were as follows. 1) From seven salmon 202 anisakid larvae were found, and mean infection number of anisakid larvae per individual salmon was 28.86. 2) From total extracted anisakid larvae 198 larvae(98%) were found in muscle. Therefore the distribution of anisakid larvae in intestine was extremely rare compared to in muscle. 3) The percentage of anisakid larvae in II, IV muscle region was 93% and from this we could surmise that most anisakid larvae in salmon did not penetrate to the very distanted muscle from intestine. 4) Three types of anisakid larvae(Anisakis Type I, Contracaecum Type B, Contracaecum Type D) were identified and, among them, Contracaecum Type B was the first recording type in Korea 5) Larvae of Contracaecum it genus were found only in intestine. Therefore it surmised that penetration neture to muscle of Contracaecum larvae was less than that of Anisakis Type I.

Recently, lots of research results on program comparison have been reported since the code theft become frequent as the increase of code mobility. This paper proposes a plagiarism detection method using class structures. The proposed method constructs a graph representing the referential relationship between the member variables and the methods. This relationship is shown as a bipartite graph and the test for graph isomorphism is applied on the set of graphs to measure the similarity of the programs. In order to measure the effectiveness of this method, an experiment was conducted on the test set, the set of Java source codes submitted as solutions for the programming assignments in Object-Oriented Programming course of Pusan National University in 2012. In order to evaluate the accuracy of the proposed method, the F-measure is compared to those of JPlag and Stigmata. According to the experimental result, the F-measure of the proposed method is higher than those of JPlag and Stigmata by 0.17 and 0.34, respectively.
