  • Patients who visit the emergency room with urinary stones have difficulty lying down in a supine position due to severe pain when performing the KUB test. The purpose of this study was to find methods to reduce the patients' pain and image distortion, and obtain medical images with high diagnostic values. After checking the standard classification of disease and cause of death, the target group consisted of 121 patients who had clearly distinguished stones from computed tomography. Patients with stones in the ureteralvesical junction were excluded. Qualitative image evaluation was performed by confirming the location of the stone in the computed tomography images. and evaluated the rate of visual discrimination of stones possible through KUB and abdominal plain X-ray. Quantitative image evaluation was performed on the KUB, abdominal plain X-ray images. The transverse process of the first lumbar vertebrae served as the standard point, and the length from this point to the lower part of the stone was measured. Results from looking at the rate of visual discrimination of stones possible through KUB and abdominal plain X-ray showed: 94 patients (77.6%) for KUB images and 91 patients (75.2%) for computed tomography images. The standard deviation for KUB and abdominal X-ray was 3 (2.4%). Comparing and analyzing the location from KUB images and abdominal plain X-ray images, the stone position was 10.1 mm in the kidney, 10.5 mm in the ureteropelvic junction, and 9.7 mm in the ureters. It was shown that the stone moved 10 mm on average with significant statistical difference (P<0.05). In cases where the pain is so severe that it is impossible to perform the test in the supine position, an alternative may be to check the stone position by performing a modified KUB test by having the patient stand in a vertical position. In the future, this will provide convenience to both the examiner and the patient when performing the examination, and it will contribute with its reproducibility.

  • The evaluation of GB stones with ultrasound has proved to be useful procedure in patient with symptoms of cholelithiasis. GB is evaluated for size, wall thickness, presence of internal reflections within the lumen and posterior acoustic shadowing or enhancement in Ultrsonography. The patient position should be shifted during procedure to demonstrate further the presence of stone within the GB. Patient scanned at the Rt. subcostal region in supine, right lateral, Lt. down decubitus, and upright sitting position. So GB stone should shift to dependent area of GB. Often, GB is not markedly distended in the presence of cholethiasis, and so the diagnosis becomes more difficult. One of the more difficult areas for detection of a GB stones are embeded in the cystic duct region. And since the GB is adjacent to the duodenum and hepatic flexure, its may be difficult to visualizing a GB stone. When patient study position changes frome supine to other position, stones displaced the site. But if its are polyps, not changes the site whatever patient positions. It is very important to what make different GB stones or polyps. We have studied about mobility of GB stones according to the patients position(supine, Lt. down decubitus, $30^{\circ} LAO. sitting and hand-knee). So we have a result, stones wherever localized within the GB, changed 100% its position in the hand-knee position and the others appeared at least 90%. In this study, when a large stones are located through fundus-body and body-neck, does not changing the stones position in spite of varied patient's positions. But hand-knee positions can identified GB stones, because its make changed the position of stons from posterior wall to anterior wall within the GB. We recommend the hand-knee position for differentiation GB stones from polyps.

  • In recent years, as an effort to grasp the leading position in the field of maritime trading, new ports and container terminals arc now under construction. Old ports are extended. At the beginning, stones were thrown down to form stone embankments, that is stone-dams, in the outer and inner boundaries of the planned reclamation-land. S.C.P(Sand Compaction Pile) works are often needed to improve the stability of stone-dams, where marine sediments arc relatively thick. Here, interests are centered on the shape of stone body. In this, drilling work won't provide a sufficient resolution. In addition, the result corresponds to only one borehole point information. Thus, the aim of this paper is to introduce an affordable technology, that is, a combined geophysical method(seismic tomography + Televiewer) enables to get the whole information about stone-dam section. The measuring and evaluating procedure is described in detail with an emphasis on dealing with the use of seismic detonator, proper borehole deployment and integrated data analysis. Examples of field experiments at Busan new port are illustrated, which will prove the benefit of combined geophysical method.

  • In this study, influence of different stone powders (SP), including limestone powders (LP), quartzite powders (QP), and granitic powders (GP), on the hydration behaviors of portland cement, for example, setting time, hydration heat, and hydration products, were discussed. The initial and the final setting time both shorten when the content of LP is 5 %, however, they are slightly delayed by the other two SPs. The LP has no obvious influence on the arrival time of the first peak in the exothermal curves, and it makes the peak value decrease; the other two SPs postpone the appearance of the first peak, and they also make the peak value decrease. For the second peak, LP shifts the peak position to the left, QP has no effect on this peak position, and GP makes the appearance of this peak delayed by 143 min. Similarly, three kinds of SPs have different influence on the hydration products of portland cement. The LP precipitates the formation of hydrated calcium carbo aluminate, the QP the formation of hydrated garnet, and the GP makes the amount of Tobermorite increase.

  • The stone fragments that are missing from the stone cultural heritage have limited use beyond being directly fitted to identify their original position, as they are relatively heavy and bulky, and there is the further risk of secondary physical damage during manual work. Therefore, in this study, morphological relationships between the missing parts and the stone fragments were identified through digital restoration, and a three-dimensional (3D) printed replica was created for use at the exhibition for Stone Buddhas in Four Directions in Hwajeon-ri, Yesan, where 72 stone fragments had been excavated together. First, for the digital restoration, stone fragments of similar shapes were selected after the coordinates of the 3D scanning model were aligned in virtual space. In addition, the stone fragments were printed using a 3D printer to check whether they were physically related to the missing parts. Thus, the original positions of a total of nine stone fragments were identified. To utilize these research results in the exhibition, a 1:1 replica of the Stone Buddhas in Four Directions was produced using 3D printing technology, and the nine stone fragments were also restored to their original positions. The digital technology used in this study is of great importance in that it not only made up for the limitations of the direct manual method but also suggested the possibility of expanding its application to the fields of documentation, restoration, and replication of similar cultural heritage.

  • This study reports the costume changes and the factors of the changes from stone status in joseon dynasty. It can be summarized as follows: First, the artisan for the statues is one of the most important factors for the costume changes. The artisans who were involved in building the King's tomb were also made the stone statues for scholars' tombs. This results in that the style of the King's tomb influenced the costumes of stone statues for scholars' tombs. Some craftsmen who were buddhist monks also influenced the introduction of buddhist arts. Second, the stone statues are classified into 3 types according to the dead's social position: the civil officer statues, the military official statues, and the servant statues are installed for the civil officer, the military officers, and others, respectively. This principle was applied well. However, the civil official statues are mainly installed in late joseon dynasty because the civil officers are socially preferred to the military officers in late joseon dynasty. Third, there are two types of civil officer statues; Gongbok type and jobok type. Civil officer statues of Gongbok type were mainly installed in early joseon dynasty and civil officer statues of jobok type were begun to be installed in the early 16th century. Civil officer statues of Gongbok type were fade out after the late 17th century. Fourth, there are three reasons why civil officer statues of jobok type were installed at the officers's tombs 270 years earlier than at the Kings' tombs: 1) Introduction of Daemyunghoejeon and its application, 2) an establishment of a system that requires to prepare jobok individually, and 3) self-confidence of scholars' class on political and cultural maturity.

  • The purpose of this study is to examine the characteristics of the location and the spatial composition of Uireung that is located in Seokgwan-dong, Seongbuk-gu, Seoul, in order to understand the landscape architectural characteristics. The results are as follows. First, Uireung is 6.4km from Changdeokgung Palace and 5.5km from Heunginjimun Gate. It did not violate the distance standard (40km) for the royal tombs according to Joseon Dynasty Neung-won Myo-je. Second, Uireung is in harmony with the nature and shows the authoritative characteristics of the royal authority through the spatial composition and rank(Entrance Area, Ceremonial Area, Burial Area). Third, there are burial mound, stone sheep, stone tiger, stone table, stone watch pillars in the upper platform, and stone civil official, stone horse, stone lantern in the middle platform, and stone military official, stone horse in the lower platform, and T-shape shrine, worship road in the ceremonial area. There is no pond and a tomb keeper residence, but the position, size, and form can be approximated through historical research materials. There are a colony of pine trees around the burial mound and 64 species of trees such as pine tree, zelcova tree, and fir tree below the burial mound.

  • PURPOSE. The objective was to evaluate canine positions, intercanine tip width (ICTW) and width of distal surface of canine (WDC), related to facial landmarks including interalar width (IAW), intercommissural width (ICoW), and distance between left and right projection lines drawn from inner canthus of eyes to alae of the nose (DPICa) in a group of Thai. MATERIALS AND METHODS. One hundred Thai subjects aged 18-35 years were selected. IAW and ICoW were measured on subject's face using digital vernier caliper. Irreversible hydrocolloid impression of the upper arch was taken, and a cast was poured with dental stone. Silicone impression material was used to take imprint of the incisal edge of upper six anterior teeth. DPICa was obtained from the subject's face using custom-made measuring equipment and marked on the silicone incisal imprint. The marks were then transferred from the imprint to the stone cast and measured with digital caliper. The ICTW and WDC were also measured on the stone cast. Pearson's correlation was used to determine the correlation. RESULTS. The results revealed that the correlation between ICTW-ICoW was 0.429 and ICTW-DPICa was 0.573. The correlation between WDC-ICoW was 0.426 and WDC-DPICa was 0.547. However, IAW did not show any correlation with ICTW or WDC (P>.05). CONCLUSION. The correlation between canine position and facial landmarks was found. ICTW and WDC had relationship with ICoW and DPICa. DPICa showed stronger correlation with the position of maxillary canine than that of ICoW.
