Fatigue cracks due to thermal stratification or corrosion in pipelines of nuclear power plants can cause serious problems on reactor cooling system. Therefore, these cracks must be detected before the crack growth to ensure the reliable operation. Ultrasonic techniques have been employed for detecting and sizing these fatigue cracks propagated from the back wall of pipelines. But, it is very difficult to sizing fatigue cracks because of low amplitude of the diffracted tip signal, high noise signal and ultrasound transmission through the closed crack surface. In this study, the signal reflected from the back wall is adopted instead of weak tip signals. In addition, the rate of decrease in amplitude of reflected signals due to reflection at the crack surface and diffraction at the crack tip is used to size fatigue cracks.

Highway bridges are subjected to dynamic loads when traversed by the vehicles. The vehicle-induced vibrations of bridge depend on the following factors: vehicle speed, type of bridge and its natural frequencies of vehicle, and the profiles of approach roadway and bridge deck. Impact is generally used to describe the increase in deflection{or stress) due to the dynamic nature of traffic loads, In design phase, therefore, to allow for the effect of dynamic action, the static live load is increased by a impact factor given in bridge design specification. In this study, we consider the impact factor of bridge for vehicle property. Impact fact estimated that the data by traveling test of the real bridge was used experimental method. Also, fortran program was developed about bridge-vehicle interaction. After the modeling of bridge and vehicle does. Impact factor was evaluated analysis method by interaction analysis of the program.

과립상 세포종은 Schwann 세포 기원으로 생각되며 인체에 비교적 드물게 발생한다. 과립상 세포종은 전신 어느 곳에서나 발견될 수 있으나 주로 혀, 구강, 피부 혹은 유방 등에서 호발하며 드물게 위장관에서 발견된다. 위장관에서는 식도에서 가장 호발하며 다음으로 위, 대장 순이다. 과립상 세포종은 대부분, 특히 위장관에서는 양성이며 소수의 악성 병변이 보고되었다. 이러한 이유와 함께 수술 전의 진단이 어렵기 때문에 과립상 세포종에 대한 근본적인 치료는 현재까지 외과적 절제술이다. 최근에 시도되는 치료방법들로는 내시경적 레이저 치료, 용종절제술, 내시경적 점막 절제술 등이 있다. 저자들은 상부 소화관 내시경검사를 시행하여 식도 과립상 세포종을 진단하고 내시경적 점막 절제술을 시행하여 합병증 없이 퇴원하여 현재 재발없이 경과 관찰중인 1례를 경험하였기에 보고하는 바이다. Granular cell tumors, which occur infrequently, are probably of Schwann cell origin. They can occur almost anywhere in the body but usually affect the tongue, oral cavity, skin, or breasts and are rarely found in the gastrointestinal tracts. The esophagus is the most frequent gastrointestinal site, followed by the stomach and the colon. Granular cell tumors are generally benign, especially in the gastrointestinal tract, some malignant lesions have been reported. For this reason, and also because preoperative diagnosis is difficult, the standard treatment for granular cell tumor has until now been surgical excision. In recent years, other therapeutic methods is endoscopic laser therapy (ELT), polypectiomy, endoscopic mucosal resection (EMR). We report a case of esophageal granular cell tumor which was diagnosed by an endoscopy and managed using an endoscopic mucosal resection without complication.

It is one of the important design concept th lead a ductile failure at the ultimate state for the concrete structures. If a ductile failure occurs, we can observe and predict the failure process of members and structure. Therefore, we can either avoid or count move to the collapse for the ductile failure energy. Most of the previous studies on ductility are focused on reinforced concrete members. Prestressed concrete members are supposed to be less ductile than reinforced concrete members, because the prestressing tendons have less ultimate strain. To see the ductility and re-distribution effect of prestressed concrete members, we need and experiment of the statically indeterminate members. We carry out an experiment of prestressed concrete two span continuous beam, to compare the ductile behavior. From the test, we observe that the ultimate rotation capacity of the prestressed concrete members are less than predicted by theory. It means the prestressed concrete members has more ductility than prediction, which gives conservative results in design. It needs more precise analysis to consider stain hardening of reinforcing bars and tendons to follow up the test results.

This study was made to analysis of taste compounds in extracts which may participate in flavor and taste, in dried Prawn. Penacus japonicus. The changes of such compounds during sun during as free amino acids were analyzed. The results are summarized as follows : Among the free amino acids analyzed, glycine, arginine, proline, taurine and alanine were found in large amounts in the raw extracts, the amount of valine, methionine, isoleucine, leucine and tyrosine were low. The free amino acids were not changed in composition but the decrease of total free amino acid was approximately 588 mg% during sun during. In sun dried prawn, glycine, arginine, taurine, proline and alanine were abundant too.

We have experienced a case of presacral ganglioneuroma. So, we report a peripheral ganglioneuroma of sacral origin. The patient is 34-year-old man with intermittent low back pain and right sciatica. Myelographic computed tomography revealed extradural lobulated low attenuated tumor lesion within spinal canal at the level of L5 and S1. Tumor indented the thecal sac to the left side, and extended into the pelvic cavity through the intervertebral foramen between S1 and S2. The mass was surgically excised and turned out to be ganglioneuroma pathologically.

Generally, headed reinforcement offers several advantages over straight bar or hooked bar anchorages to develop reinforcement in concrete members. The purpose of this study is to investigate the shear behaviors of reinforced concrete deep beam with headed reinforcement. Five deep beam specimens are designed to study the anchorage capacity of headed reinforcement as well as the contribution of H-bar and V-bar to the shear. Two anchorage types, standard 90-degree anchorage and headed reinforcement, are considered in design. From the tests, it is shown that In the test results, headed reinforcement is able to replace standard 90-degree anchorage as the anchorage method. The evaluation on the contribution of H-bar and V-bar in current design code for deep beam shows that the former is overestimated 75% and the latter is overestimated 17%.

Photocatalytic inactivation of Microcystisaeruginosa was carried out with the TiO₂-coated pyrex hollow glass beads under the illumination of UV light(370㎚ wavelength). After being irradiated with UV light in the presence of the TiO₂-coated pyrex glass beads, Microcystis aeruginosa, known as typical cyanobacteria, lost their photosynthetic activity, and the colonies of Microcystis cells were completely separated into individual spherical one. Complete photocatalytic inactivation of Microcystis aeruginosa was obtained in about 30min. Photosynthesis activity of the cyanobacteria could be inhibited effectively after being reacted photocatalytically with TiO₂ immobilized hollow glass ball.

Choledochal cysts are congenital dilatation of the biliary tree occurring predominantly in female. Most of the cases are diagnosed during childhood, and its presentation during pregnancy or postpartum period is rare. Choledochal cysts during pregnancy are frequently associated with complication due to the concealment of the mass by enlarged uterus. Rupture of cyst is a rare complication that occurs spontaneously in most cases. We experienced a case of ruptured choledochal cyst during pregnancy in a 28-year-old primigravida. It occurred at 32 weeks of pregnancy. A premature newborn was delivered by normal vaginal delivery. The choledochal cyst was excised, and reconstruction was carried out by Roux-en-Y choledochojejunostomy. Although choledochal cysts occurring in pregnancy are rare, it is important to be aware of the condition because a missed or delayed diagnosis may be catastrophic for both mother and child.
