Purpose: Advancement of computed tomography (CT) hardware and software has allowed thin section scanning and reconstruction of fascinating 2-dimentional (2D) and 3- dimentional (3D) images. Especially, the reconstruction of 3D images of gastrointestinal tract has been used in the detection and diagnosis of pre-malignant and malignant diseases. To compare the efficacy of CT gastrography with conventional upper gastrointenstinal series (UGIs) in gastric cancer patients. Materials and Methods: During Nov. 2002 and Mar. 2003, twenty-seven patients who had gastric cancer received both double contrast upper GI series and CT gastrography prior to radical surgery. Among these patients, nineteen had early gastric cancer (EGC) and 8 had advanced gastric cancer (AGC). Fifteen patients were male and 12 were female. The mean age was 54 yrs (range, $27\∼75$ yrs). The patients were placed on NPO and Stomach was distended with gas in fasting state prior to CT scanning. Double contrast upper GI series were performed as routine manual. CT scan was conducted in all patients using 8 or 16-channel multidetector CT in this study. The collimation and reconstruction for CT scanning were set at 2.5 mm and 1.25 mm, respectively. CT scanning was performed in the supine position. For image processing, CT gastrography, in which raysum and surface rendering images were constructed, virtual and 2D image in coronal and sagittal images were performed. The detectability of gastric cancer was assessed between UGIs and CT gastrography. Results: In AGCs, the detection rate of cancer using CT gastrography and virtual gastroscopy was higher than EGC cases. However, CT gastrography and virtual gastroscopy showed less favorable results than UGIs. Even though only a small number of cases had been studied, we might conclude that CT gastrography and virtual gastroscopy could replace UGIs in the detection of AGC cases. Conclusion: The detection rate used with CT gastrography and Virtual gastroscopy is not better than that of UGIs in early gastric cancer, however, in advanced gastric cancer cases, it is nearly equal to that of UGIs.

FADS1 (fatty acid desaturase 1) plays a crucial role in fatty acid metabolism, and it was recently reported to be involved in tumorigenesis. However, the role of FADS1 expression in esophageal squamous cell carcinoma (ESCC) remains unknown. In the current study, we investigated the expression and clinical pathologic and prognostic significance of FADS1 in ESCC. Immunohistochemical analyses revealed that 58.2% (146/251) of the ESCC tissues had low levels of FADS1 expression, whereas 41.8% (105/251) exhibited high levels of FADS1 expression. In positive cases, FADS1 expression was detected in the cytoplasm of cells. Correlation analyses demonstrated that FADS1 expression was significantly correlated with tumor location (p=0.025) but not with age, gender, histological grade, tumor status, nodal status or TNM staging. Furthermore, patients with tumors expressing high levels of FADS1had a longer disease-free survival time (p<0.001) and overall survival time (p <0.001). Univariate and multivariate analyses revealed that, along with nodal status, FADS1 expression was an independent and significant predictive factor (p<0.001). In conclusion, our study suggested that FADS1 might be a valuable biomarker and potential therapeutic target for ESCC.

Objective: The aim of the study was to evaluate the efficiency of the Hankins and Howe (HH46), Valadares Filho (V06), and Marcondes (M12) equations for predicting the physical and chemical composition of dairy crossbred bulls carcasses, as well as the chemical composition of their empty bodies. Methods: This study was conducted using 30 dairy crossbred bulls. One group of five animals was slaughtered at the beginning of the experiment, and the remaining were slaughtered 112 days later. Animals were distributed in a completely randomized design into treatments consisting different levels of concentrate (0%, 17%, 34%, 51%, and 68%). The physical and chemical compositions of the cattle were obtained from the right half of the carcass and using samples taken between the 9th and 11th ribs of the left half of the carcass. The estimated and experimentally determined values were compared using the correlation and concordance coefficient, as well as the mean square error of prediction (MSEP) and its components. Results: The HH46 equations were better at estimating the amount of muscle plus fat in the carcass. The amount of bone in the carcasses could not be well estimated by the HH46 and M12 models. The M12, HH46, and V06 equations were worst at estimating the amounts of protein, ether extract, and water in the carcass, respectively. In the empty body, the amounts of protein and water were well estimated by the HH46 equations. Protein, ether extract, and water were accurately estimated by the V06 equations, and ether extract by the M12 equations. Conclusion: The physical and chemical composition of dairy crossbred bull carcasses, as well as the chemical composition of their empty bodies, can be predicted using the equations tested here. The amount of bone in these carcasses could not be accurately predicted.

In connection with international commercial arbitration the need to seek interim relief is generally recognized. Interim reliefs address the requirements of a party for immediate and temporary protection of rights or property pending a decision on the merits by the arbitral tribunal. The most common forms of interim relief are attachments and injunctions. If the arbitral tribunal has not yet been appointed, an application for interim relief must usually be addressed to the local courts at the place of commercial arbitration. If the arbitral tribunal has been appointed, the application for interim relief is first made to the arbitral tribunal. Interim relief by the arbitral tribunal is in the form of a direction to the parties. Since the arbitral tribunal has no enforcement power, it may be necessary to have a arbitral tribunal's direction confirmed by a local court which can enforce its order. The New York Convention does not provide for interim reliefs. The question is whether Article II(3) of the New York Convention that the court "shall, at the request of one of the parties, refer the parties to arbitration" denies jurisdiction to courts to grant interim reliefs in international commercial arbitration. Some cases have indicated that the U. S. court have no power to grant interim relief. Other cases have indicated that the U. S. courts do have the power to grant interim relief. It is unlikely that a U. S. court will order interim relief in relation to an commercial arbitration in a foreign country. Article 26 of the UNCITRAL Arbitration Rules provides with respect to interim measures of protection. Section 1 of Article 26 of UNCITRAL Arbitration Rules provides that the arbitral tribunal may take any interim measures it deems necessary in respect of the subject matter of the dispute, including measures for the conservation of the goods forming the subject matter in dispute. This article gives the arbitral tribunal the broadest authority, not limited to safeguarding property. Article 17 of the UNCITRAL Model Law on International Commercial Arbitration provides that the arbitral tribunal may order any party to take such interim measure of protection as the arbitral tribunal may consider necessary in respect of the subject matter of the dispute. It may be noted that the article does not deal with enforcement of such measures. The International Chamber of Commerce Rules of Conciliation and Arbitration do not expressly empower the arbitral tribunal to grant interim reliefs. However, Article 8.5 of the ICC Rules of Conciliation and Arbitration provides that the parties shall be at liberty to apply to any competent judicial authority for interim measures. In conclusion, the power of the arbitral tribunal to provide interim reliefs is generally recognized in the arbitration rules of arbitral institutions. However, the arbitral tribunal's authority is limited by its lack of enforcement mechanisms. It is generally recognized that the local courts have power to grant interim reliefs in aid of an commercial arbitration. However, local courts are reluctant to grant interim reliefs if that decision requires an adjudication of issues within the special competence of the arbitral tribunal.

Recently many Korean large-sized construction companies as well as specialty contractors have been expanding their business in the overseas market to mitigate impacts from long-term stagnation in the domestic market. Such as a result, it has been arisen as a major issue that contractors effectively manage the delays which have been commonly faced with in international mega-projects. Therefore it can be said that the ability of the delays management leads a success of project. This paper presents a review of literature for delay analysis methods such as time impact analysis(TIA) and raises practical problems to rationally substantiate the duration of extension of time(EoT) in international mega projects which have wide scope of works as well as complicated and detailed contract baseline programs by taking theoretical approaches. We suggest the two improvement concepts to substantiate the EoT claims which are effectively applicable to practical projects. The first is to sort out dominant delays among numerous delays in advance of applying a delay analysis. The second is to set up the delay sections with the advanced concept for analysing delays' effects by TIA. This study performed a case study on an actual international mega-project. to confirm the effectiveness of improvement concepts that this practical approach is applicable for the assessment of EoT. In conclusion, this paper supposes to provide practitioner in charge for an EoT claim with an advanced substantiation methodogy when they not only analyse the construction delays by using TIA, but also negotiate with stakeholders about with the assessment of EoT.

Objective : To find risk factor and symptoms for transferred newborn from postpartum care center Method : We performed a follow-up study using medical record. Subjects comprised 188 neonates(include 4 twins) and 184 women in childbed who were hospitalized in oriental postpartum care center from January, 1, 2002 to December, 31, 2002. Result: Transferred newborn was total 24, N.V.D. 17, C.S. 7, male and female were 12 separately. The symptom of transfer was fever(16), diarrhea(4), jaundice(3), convulsion(1) Transferred number and rate was male 12(10.7%), female 12(15.8%). In delivery method, total normal vaginal delivery(N.V.D.) was 136 and transferred 17(12.5%), total cesarean section(C.S.) was 52 and transferred 7(13.5%). Transferred rank was N.V.D. female(17.9%). C.S. male(15.6%), C.S. female(10%), N.V.D.(8.6%). Of the 188 neonates. immature infants were 2 and transferred 1(50%), term infants were 184, transferred 23(12.5%), post-term infants were 2 and transferred none(0%). In age of women in childbed, transferred ratio was 15.4%(over 35), 15.2%(25-29), 10.5%(30-34). In fever,. C.S. infants were more transferred than N.V.D. and male infant had a tendency to transfer in later period of hospitalization and female in early period. It seems that transfer was related to abortion. In diarrhea, all was N.V.D. and their diagnosis was rotavirus. The average age of women in childbed was yonger(28.5). In jaundice, all was 1st, and average birth weight was lighter(3153g). The average age of women in childbed was older(30). In convulsion, birth weight was lighter(3153g), and age of women in childbed was older(30). Conclusion : There's any relation with sex and delivery method, birth weight and mother's age in transfer. But we cannot find any statistically significance. Further prospective studies are needed to find risk factors in transfer.

This experiment was conducted to study the effects of nitrogen top-dressed at the different growth stages on the morphological and physical characteristics of barley culm. The results obtained are summarized as follows: 1. By top-dressing of nitrogen in March, each internode length from the third to the fifth internode was shortened, and total fresh weight of the top, dry weight per unit culm, inside or outside culm diameter and thickness of culm were increased. Therefore these characteristics related to lodging indicated the beneficial changes for lodging resistance by top-dressing of nitrogen in March. 2. Both weight of culm at breaking and bending moment of culm at breaking, expressing lodging resistance of culm, were increased in the plots of nitrogen top-dressed in March. Accordingly lodging resistance became higher by top-dressing of nitrogen in March. 3. Both section modulus and secondary moment of inertia, expressing bending stiffness of culm, were increased by top-dressing of nitrogen in March. Accordingly lodging index, expressing comprehensive lodging resistance, became low by top-dressing of nitrogen in March. 4. Both spike weight and grain yield were increased by top-dressing of nitrogen in March. Consequently we came to the conclusion that the suitable top-dressing time of nitrogen was in March.

Purpose - This study examines the impact of oil price volatility on economic activities in Korea. The new millennium has seen a deregulation in the crude oil market, which invited immense capital inflow into Korea. It has also raised oil price levels and volatility. Drawing on the recent theoretical literature that emphasizes the role of volatility, this paper attends to the asymmetric changes in economic growth in response to the oil price movement. This study further examines several key macroeconomic variables, such as interest rate, production, and inflation. We come to the conclusion that oil price volatility can, in some part, explain the structural changes. Research design, data, and methodology - We use two methodological frameworks in this study. First, in regards to the oil price uncertainty, we use an Exponential-GARCH (Exponential Generalized Autoregressive Conditional Heteroskedasticity: EGARCH) model estimate to elucidate the asymmetric effect of oil price shock on the conditional oil price volatility. Second, along with the estimation of the conditional volatility by the EGARCH model, we use the estimates in a VECM (Vector Error Correction Model). The study thus examines the dynamic impacts of oil price volatility on industrial production, price levels, and monetary policy responses. We also approximate the monetary policy function by the yield of monetary stabilization bond. The data collected for the study ranges from 1990: M1 to 2013: M7. In the VECM analysis section, the time span is split into two sub-periods; one from 1990 to 1999, and another from 2000 to 2013, due to the U.S. CFTC (Commodity Futures Trading Commission) deregulation on the crude oil futures that became effective in 2000. This paper intends to probe the relationship between oil price uncertainty and macroeconomic variables since the structural change in the oil market became effective. Results and Conclusions - The dynamic impulse response functions obtained from the VECM show a prolonged dampening effect of oil price volatility shock on the industrial production across all sub-periods. We also find that inflation measured by CPI rises by one standard deviation shock in response to oil price uncertainty, and lasts for the ensuing period. In addition, the impulse response functions allude that South Korea practices an expansionary monetary policy in response to oil price shocks, which stems from oil price uncertainty. Moreover, a comparison of the results of the dynamic impulse response functions from the two sub-periods suggests that the dynamic relationships have strengthened since 2000. Specifically, the results are most drastic in terms of industrial production; the impact of oil price volatility shocks has more than doubled from the year 2000 onwards. These results again indicate that the relationships between crude oil price uncertainty and Korean macroeconomic activities have been strengthened since the year2000, which resulted in a structural change in the crude oil market due to the deregulation of the crude oil futures.

Purpose: Cavity growth process monitoring is to periodically monitor changes in common size and topography for general and observational grades to predict the rate of common growth. The purpose of this study is to establish a systematic cavity management plan by evaluating the general and observational class community in a non-destructive method. Method: Using GPR exploration equipment, the acquired surface image and the surrounding status image are analyzed in the GPR probe radargram in depth, profile, and cross section of the location. The exact location is selected using the distance and surrounding markings shown on the road surface of the initial detection cavity, and the test cavity is analyzed by calling the radar at the corresponding location. Result: As a result of monitoring tests conducted at a cavity 30 sites of general and observation grade, nine sites have been recovered. Changes in scale were seen in 21 cavity locations, and changes in size and grade occurred in 13 locations. Conclusion: The under road cavity is caused by various causes such as damage to the burial site, poor construction, soil leakage caused by groundwater leakage, waste and ground vibration. Among them, indirect factors could infer the effects of groundwater and localized rainfall.
