  • The anchovy, Engraulis japonica, were prepared with two different salt concentration of 20%, 10% which was added 2, 5, 5 and 10 % of grind garlic(LSA 1, 2, 3, 4) and garlic juice(LSB 1, 2, 3, 4), respectively. The experimental samples were taken at 30, 60, 90 and 110 days fermentation, which were analyzed VBN(volatile basic nitrogen), amino acids, nucleotides and their related compounds and amino acids. VBN increased rapidly until 110 days fermentation, its contents in samples containing of 10% salt(CB) were increased about 2.4 times as compared with those of 30 days fermentation. And then its contents of 110 days fermented samples increased at average 2.3 times more than 30 days fermented samples containing grind garlic of 2, 5, 8% and garlic juice of 2%. Nucleotide and their related compounds were detected AMP, UMP, IMP, inosine and hypoxanthine. Hypoxanthine was dominants in all samples and increased steadily during fermentation of anchovy. The contents of composition amino acids decreased gradually during it's fermentation, but those content decreased 33% in CO group, 42% in the CB group and 38%(average) in the other garlic added low salt groups.

  • Traditional doenjang with Lentinus edodes added at a concentration of 0, 3, 5 and 10% (w/w) was prepared and its physicochemical characteristics were analyzed during fermentation for 6 months. The moisture content, salt level and pH for doenjang were decreased with increasing addition of Lentinus edodes powder, but crude protein content was increased. Among the free sugars, glucose, galactose, arabinose, sucrose and maltose were identified and quantified, with the first two being the major free sugar. Minerals were detected in the order of Na> K> P> Ca> Mg> Fe while the content of Cu, Mn and Zn exhibited little change. The contents of each amino acid of traditional doenjang with added Lentinus edodes, glutamic, leucine and aspartic acids, had a much higher level. In fatty acid compositions, palmitic, stearic, oleic and linoleic acids were analyzed, with oleic acid being the most abundant fatty acid at $56.4{\pm}0.8\sim57.5{\pm}0.5%$ in all the tested samples. GMP and IMP contents of nucleotides and their related compounds were extremely high. It was thought that these substances contributed to the sweet taste of traditional doenjang with added Lentinus edodes. These results showed the applicability and high quality of traditional doenjang with added Lentinus edodes.

  • Previous studies have been focused on the voltage of Bypass diode and Isc(Short Circuit Current) of the influenced solar cell. The Bypass diode starts working when it gets the reverse applied voltage. Previous studies have only concentrated on Isc of the influenced solar cell and Imp of PV module to explain the bypassing performance. PV module is usually working together with inverter having MPPT(Maximum Power Point Tracking) function for best performance. bypassing point is regulated by MPPT function of inverter. In this paper, simulation results of Bypass diode in PV module have been analyzed to represent the relationship of the bypassing point with the composition of PV module. From the results, the more cells are connected with each string, the earlier bypassing performance happens under the fixed number of strings. As diode groups increase or irradiation decreases, the bypassing performance starts fast.

  • Powder and liquid products of the seasoned and smoked fish were manufactured with small-sized skipjack tuna (Euthynus pelamis) captured in the East Sea, Korea. The property changes of nucleotides and their related compounds, amino acid, and sensory attribute during storage were analyzed. IMP content was the highest among the nucleotides and their related compounds followed by inosine in both powder and liquid products. Nucleotides and their related compounds of the powder product increased slightly as storage period increased, while those of liquid product were constant. Glutamic acid $(15.6{\%})$, aspartic acid $(10.7{\%})$, and lysine $(9.3{\%})$ were major amino acids of the power product, while histidine $(36.2{\%})$ and taurine $(10.6{\%})$ were high in the liquid product. Free amino acid contents of liquid product increased during storage periods. There was no significant difference In the concentration of nucleotides and their related compounds, and composition of free amino acid between the products with/without liquid smoke. Aroma and acceptance were good in both products, while bitterness and sweetness were poor.

  • In the case of Quine Mccluskey's methode for Boolean function minimization, we have to examine each bits of binary represented minterms. In this paper, cube relations between misterms that are represented by means of decimal number, and all sorts of rules for Boolean function minimization are described as theorems, and they are verified. And based on these theorems, the new fast algorithm for Boolean function minimization is proposed. An example of manual operation is sholvn, and the process is writed out by a FORTRAN program. In this program, the essential pl.imp implicants of the Boolean function that has 100 each of minterms including redundant minterms, are finked and printed out, (the more minterms can be treated if we take the more larger size of arrays) and the outputs are coincided with the results of manual operation.

  • HPLC separation of ionic samples tends to be more complicated and difficult to understand than that of non-ionic compounds. On the other hand, band spacing is much more easily manipulated for ionic than for neutral samples. Ion-suppression RP-HPLC method was used with organic modifier and aqueous buffer solution. In this work, five mononucleotides of cytidine-5-monophosphate (5-CMP) disodium salt, uridine-5-monophosphate disodium salt (5-UMP), guanosine-5-monophosphate disodium salt (5-GMP), inosine-5-monophosphate disodium salt (5-IMP), and adenosine-5-monophosphate disodium salt (5-AMP) were examined. Acetic acid and sodium phosphate were used as buffers, and methanol as an organic modifier. A new relationship between the retention factor and the buffer concentration at a fixed modifier content (5% of methanol) could be expressed by following: K = (k(sub)-1 + k(sub)0 (k(sub)B/k(sub)S)/(1 + (k(sub)B/k(sub)S) C(sub)B(sup)a), where C(sub)B was the concentration of buffer. Using this relationship, the calculated values closely matched the experimental data. The derived relationship showed that as the buffer concentration increased, the retention factor approached a certain value, and this was buffer dependent.

  • Endo- and exoproteases were used to hydrolyze Alaska pollack processing scrap. In 2 stage hydrolysis, the optimal conditions by Protamex were: temperature, $45.8^{\circ}C$; pH, 6.73; enzyme concentration, 0.11%; time, 105.5 min, whereas those by Flavourzyme were: temperature, $42.0^{\circ}C$; pH, 6.54; enzyme concentration, 0.28%; time, 20.4 hrs. But, the optimal conditions of 1 stage hydrolysis by equal proportion of Protamex and Flavourzyme were: temperature, $52.9^{\circ}C$; pH, 6.3; enzyme concentration, 0.46%; time 10.9 hrs. The contents of carbohydrate and ash were higher in the 2 stage hydrolyzate than the 1 stage, while that of crude lipid was in the reverse order. There were no significant differences in the contents of moisture and crude protein between both methods. The contents of total creatine and IMP, and viable cell counts were higher in the 1 stage hydrolyzate than the 2 stage, while the contents of TMAO, TMA, and Hx was in the reverse order. But, there were no significant differences in the contents of amino-N and color between both methods. The free amino acid contents of the 1 and 2 stage hydrolyzate were 2,741.77 and 3,529.47 mg/100 mL, respectively.
