Computer programs called "PCBRG" and "PCPST' were developed to analyze and design the prestressed concrete bridge. PCBRG is a structural analysis program which can determine the member forces, displacements and adaptable area of tendon by iteration method. PCPST is a post-processor for design. It enables design variables verified and the results of analysis (stress, member force and displacement, etc) are presented in the screen. Also the shear force and bending strength by the deformation compatibility method were checked.

멸치젓의 呈味成分에 관한 기초자료를 얻고자 생멸치와 이를 原料로 하여 제조된 멸치젓 중의 核酸關聯物質, 유리아미노산, betaine, TMAO, TMA 및 總creatinine을 分析하였다. 核酸關聯物質 중 생멸치에서는 IMP가 乾物量基準으로 2.8 μmole/g로 가장 많았으나 멸치젓에서는 hypoxanthine이 4.2 μmole/g으로 가장 많았고 , ATP는 흔적량에 불과 하였다. 멸치젓 중의 유리아미노산 중 함량이 많은 것은 leucine, isoleucine, phenylalanine, lysine, tyrosine, alanine, histidine, valine, methionine의 順이었고 glycine, proline, glutamic acid, arginine, threonine, serine 등은 함량이 적었다. 그리고 全유리아미노산은 젓갈 숙성중생원료에 비하여 약 2배로 增加 하였다. Betaine 은 생멸치 및 멸치젓 중에 各各 10.2㎎/100g, 30.0㎎/100/g였으며 이들이 엑스分室素에 대한 比率은 各各 0.6% 및 1.2%였다. TMAO 含量은 생멸치가 13.9㎎/100g, 멸치젓이 9.0㎎/100g였으며 TMA 含量은 各各 22.7㎎/100g 및 30.9㎎/100g였다. 總 creatinine 含量은 생멸치 및 멸치젓에서 各各 433.1㎎/100g, 575.8㎎/100g로서 엑스分室素에 대해 27.2% 및 22.8%였다. Omission test 結果 멸치젓의 呈味成分으로서는 유리아미노산 및 核酸關聯物質이 중요한 구실을 한다는 것을 알았다. This study was conducted to evaluate the taste compounds of fermented anchovy. The contents of such compounds as nucleotides and their related compounds, free amino acids, betaine, TMAO and total creatinine raw and fermented anchovy were analysed. The contents of IMP in raw anchovy appeared higher than other nucleotides and tended to decrease rapidly during fermentation. Therefore, in the case of fermented anchovy, hypoxanthine was abundant and IMP was very low in content. In the free amino acid composition of fresh samples abundant amino acids were leucine, isoleucine, phenylalanine, lysine, tyrosine, alanine, histidine, valine, methionine in order. Such amino acids as glycine, proline, glutamic acid, arginine, threonine and serine were poor in content. The contents of total free amino acids reached approximately about two times as compared with that of raw sample. The amount of betaine and TMA increased, while TMAO decreased during fermentation. The content of total creatinine in raw and fermented anchovy was occupied 22.8% and 27.2% of total of extractive nitrogen, respectively. As the results of omission test, the taste-active compounds of fermented anchovy are assumed to be free amino acids and nucleotides.
