PURPOSE. This study was conducted to evaluate the influence of the implant-abutment connection design and diameter on the screw joint stability. MATERIALS AND METHODS. Regular and wide-diameter implant systems with three different joint connection designs: an external butt joint, a one-stage internal cone, and a two-stage internal cone were divided into seven groups (n=5, in each group). The initial removal torque values of the abutment screw were measured with a digital torque gauge. The postload removal torque values were measured after 100,000 cycles of a 150 N and a 10 Hz cyclic load had been applied. Subsequently, the rates of the initial and postload removal torque losses were calculated to evaluate the effect of the joint connection design and diameter on the screw joint stability. Each group was compared using Kruskal-Wallis test and Mann-Whitney U test as post-hoc test (${\alpha}$=0.05). RESULTS. The postload removal torque value was high in the following order with regard to magnitude: two-stage internal cone, one-stage internal cone, and external butt joint systems. In the regular-diameter group, the external butt joint and one-stage internal cone systems showed lower postload removal torque loss rates than the two-stage internal cone system. In the wide-diameter group, the external butt joint system showed a lower loss rate than the one-stage internal cone and two-stage internal cone systems. In the two-stage internal cone system, the wide-diameter group showed a significantly lower loss rate than the regular-diameter group (P<.05). CONCLUSION. The results of this study showed that the external butt joint was more advantageous than the internal cone in terms of the postload removal torque loss. For the difference in the implant diameter, a wide diameter was more advantageous in terms of the torque loss rate.

Cultural industry along with cultural content that forms the center of cultural industry is the field whose interest is continually increasing due to the increase of weight in the national economy and the strengthening of importance in future value. Cultural content, particularly, accounts for the essential position in starting a business around one-person business, which recently arouses high interest in a nation. However, it is true that the debates on the rapid growth and identity of cultural content in contrast to the reinforcement of its position, and the criticisms about the lack in development of material and cultural content in staring a business show the limitation of overall cultural content in Korea. This research examines recognition of cultural industry or cultural content through terminologies of definition as well as the relationships of configures in accordance with the outcome of cultural content. Findings demonstrate that cultural content in Korea revealed the highest cultural orientation which is the same as existing interpretations, and as comparison objects, entertainment industry in the U.S. and creative industry in the UK contained the highest part of entertainment and creativity respectively. It reflects that mythical elements of language that has been discussed from the structuralist perspectives are projected in the relevant field. In conclusion, the conceptual definition of cultural content has the structure to project advantages and disadvantages of existing culture, and this limitation needs to be overcome in securing the items and business value in starting a business.

In order to estimate the nutritive value of roasted full-fat soybean (FFS) in carp diet, growth performance and excretion of protein and phosphorus were examined using carps having mean body weight of 111 g. Growth trial was conducted for 4 weeks using the fishes fed 5 diets (Control, $F_{24}S_{13}$, $F_{16}S_{27}$, $F_8S_{40}$ and $F_0S_{56}$) containing 32%, 24%, 16%, 8% and 0% of fish meal (F) and 0%, 13%, 27%, 40% and 56% of full-fat soybean, respectively. A total of 800 fishes were allotted randomly by groups of 40 to 5 treatments with 4 replicates per treatment. Fishes were fed to station eight times daily. Feeding trial was conducted for 4 weeks. As dietary FFS increased from 0% to 56%, weight gain of fish decreased from 91 g to 39 g and feed conversion ratio increased from 1.06 to 1.95. Protein efficiency ratio (PER) was highest (2.35) in control group which had the highest protein intake, while PER significantly decreased with decrease in protein intake as dietary FFS level increased. Although dietary protein and energy levels were maintained constant, protein excretion per kg weight gain varied from 273 g to 579 g for the groups control and $F_0S_{56}$, respectively. However, the value for control group was not significantly different to those for the groups $F_{24}S_{13}$ and $F_{16}S_{27}$. On the other hand, the highest protein retention efficiency was found in group fed the diet $F_{24}S_{13}$. Fish fed the diet $F_8S_{40}$ excreted the lowest phosphorus (P) based on kg weight gain showing the highest P retention efficiency of 62%. P excretion per kg feed intake was in the range of 5 g to 10 g for the groups $F_8S_{40}$ and $F_{24}S_{13}$, respectively. The present results indicated that as dietary FFS level increased, growth performance and feed utilization decreased while excretion of protein and phosphorus increased. Therefore, it was concluded that more than 25% substitution by FFS for fish meal could exert negative effects on growth and feed utilization of carp.
The types of test items which were recorded in this test report of quality control domestic $^{18}F$-FDG radiopharmaceutical which consisted of 13 different types: appearance, half-life, radioactive heterokaryosis, radiochemical Confirmation (measure of Rf value), radiochemical Purity, Ethanol, Acetonitrile, Kryptofix, Aluminium, pH, Endotoxin, aseptic test, and radioactivity${\cdot}$ml-1. The record was fully recorded in 'appearance', 'radioactive heterokaryosis', 'pH', 'Endotoxin', and 'aseptic test'. In 'half-life', 'radiochemical Confirmation (measure of Rf value), 'radiochemical Purity', 'Ethanol', 'Acetonitrile', 'Kryptofix', 'Aluminium', 'radioactivity${\cdot}$ml-1', there were differences in records of each manufacturing business on radioactive medicine and medical supplies. The result of the test showed all 13 items of quality control test were 100% suitable on the basis of recorded data. There were more radiopharmaceutical made in the laboratory than in hospitals and businesses and in for result of suitability test, the laboratory showed higher suitability than did the hospitals or businesses. Domestically, there are differences of the test report items in the safety of radiopharmaceutical of each facility, and since it is not standardized, supplements are needed. To submit standardized test reports of quality guarantee in radiopharmaceutical, GMP of U.S. and CE Mark of Europe should be referred as well as receiving advice from professionals to standardize as suitable domestic standard.

Background: CA125 and HE4 are used in calculating Risk of Malignancy Algorithm (ROMA); and Risk of Malignancy Index (RMI). However, studies showed that normal levels of CA125, and HE4 differ among ethnicities such as between Asians and Caucasians, thus affecting the accuracy of the RMI score and ROMA in predicting ovarian malignancy. This study aimed to determine whether new or modified cutoff values for Ca125, HE4, the RMI score, and ROMA resulted in a better prediction of malignancy compared with the previous or standard ones. Materials and Methods: Serum level of CA125 and HE4 from 128 patients with diagnosis of ovarian tumor that had been collected before surgery at Cipto Mangunkusumo General Hospital (CMH) in Jakarta from November 2010 until May 2011 were reviewed and analysed. The standard cutoff values of these biomarkers, RMI, and ROMA were modified by using logistic regression model. The modified cutoff values were compared to the standard cutoff values in terms of sensitivity, specificity, and accuracy. Results: The modified cutoff value of CA125, HE4, RMI score and ROMA were 165.2 U/mL, 103.4 pM, 368.7, 28/54. The sensitivity and specificity of the modified cutoff values CA125, HE 4, RMI score and ROMA in differentiating benign from malignant and borderline were 67% and 75,4%; 73.1% and 85.2%; 73.1% and 80.3%; and 77.6% and 86.9%. While the sensitivity and specificity of the standard cutoff value of CA125; HE4; RMI score; and ROMA were 91% and 24.6%; 83.6% and 65%; 80.6% and 65.6%; and 91.0% and 42.6%. The accuracy of modified cutoff values compared with standard cutoff values were: 71.2% vs 59.3%, 78.9% vs 75% vs, 76.5% vs 73.4%, and 82% vs 67.9%. Conclusions: The new or modified cutoff values of Ca125, HE4, RMI score and ROMA resulted in higher accuracy compared to the previous or standard ones, at the cost of reduced sensitivity.
This paper investigates accounting principles about social infrastructure on Korean National Accounting Standard and on National Accounting Standards from other countries that adopted a accruals- based national accounting standards. Social infrastructure as assets has important value in financial statements of Korea and deterioration or insufficient management of social infrastructure accompanies a huge social cost. Therefore, understanding the characteristics and related accounting standard for social infrastructure is necessary. To do this, we examine the accounting standards of U.S., New Zealand, and Australia. We also review the financial statement of local government. Based on these findings, this paper suggests that a preventive-asset management approach should be applied and alternative depreciation method for social infrastructures is developed. Moreover, a local government needs to provide important accounting information to the public in a timely and reliably manner.
Purpose: Anastomotic leakage (AL) is associated with high morbidity and mortality, high reoperation rates, and increased hospital length of stay. Here we investigated the risk factors for AL after anterior resection for rectal cancer with a double stapling technique. Patients and Methods: Data for 460 patients who underwent primary anterior resection with a double stapling technique for rectal carcinoma at a single institution from 2003 to 2007 were prospectively collected. All patients experienced a total mesorectal excision (TME) operation. Clinical AL was defined as the presence of leakage signs and confirmed by diagnostic work-up according to ICD-9 codes 997.4, 567.22 (abdominopelvic abscess), and 569.81 (fistula of the intestine). Univariate and logistic regression analyses of 20 variables were undertaken to determine risk factors for AL. Survival was analysed using the Cox regression method. Results: AL was noted in 35 (7.6%) of 460 patients with rectal cancer. :Median age of the patients was 65 (50-74) and 161 (35%) were male. The diagnosis of AL was made between the 6th and 12th postoperative day (POD; mean 8th POD). After univariate and multivariate analysis, age (p=0.004), gender (p=0.007), tumor site (p<0.001), preoperative body mass index (EMI) (p<0.001), the reduction of TSGF on 5th POD less than 10U/ml (p=0.044) and the pH value of pelvic dranage less than or equal to 6.978 on 3rd POD (p<0.001) were selected as 6 independent risk factors for AL. It was shown that significant differences in survival of the patients were AL-related (p<0.001), high ASA score related (p=0.036), high-level EMI related (p=0.007) and advanced TNM stage related

A purpose of this study, after identifying the status and type of changes derived elements that make up the Seowon(書院); landscape space and the space of the during the recent World Heritage, focusing promote the newly introduced trees listed in the important value, authenticity and integrity aspects The results can be summarized as follows. The results can be summarized as follows. Appeared trees in various old documents are 10 species; Prunus persica (L.) Batsch, Prunus mume(Siebold) Siebold & Zucc., Salix koreensis Andersson. The planting space shows regularity of some degree depends on the status of the species, essentially 3 types of Juniperus chinensis L., Lagerstroemia indica L., Phyllostachys nigra(Lodd.) Munro are primarily located in inside of seowon(書院), Zelkova serrata (Thunb.) Makino., Salix koreensis Andersson is in out side of seowon(書院). 5 types of location space to species such as Juniperus chinensis L., Ginkgo biloba L. species are the most frequently appear and it can be national representative trees. Plants which have limited vitality is a factor to prove a history of seowon(書院), it is accord with authenticity aspects that it gives meaning of symbolic to canonized figure's preference Maintenance work carried out over the years has damaged to origin of tree and thoughtlessly planted without having to go through a thorough historical research has resulted in weakening the presence of the essential space. It should preserve to features originally it have is figure reflect the viewpoint of the transformed current private to reveal the history of the various places. In conclusion, this research continues to study at the spatial dimension like a building in limited to panted, and also determine the intrinsic value of the overall spatial configuration.

Adsorption and desorption characteristics of methyl iodide at high temperature conditions up to 25$0^{\circ}C$ by TEDA-impregnated activated carbon and silver-ion exchanged zeolite(AgX-10), which are used for radioiodine retention in nuclear facility, were experimentally evaluated. In the range of temperature from 3$0^{\circ}C$ to 25$0^{\circ}C$, the adsorption capacity of base activated carbon decreased sharply with increasing temperature but that of TEDA-impregnated activated carbon showed higher value even at high temperature ranges. Especially, the residual amount of methyl iodide after desorption on TEDA-AC represented 30% lower value than that on AgX-10. However, it can be used as an adsorbent for the removal of methyl iodide up to 15$0^{\circ}C$ if it is preventing explosion by Ignition. The breakthrough curves of methyl iodide in the fixed bed packed with AgX-10 uP to 40$0^{\circ}C$ were compared upon the effects of bed temperatures, bed depth and input concentration of methyl iodide. Removal mechanism of methyl iodide on AgX-10 was proposed, based on the analysis of by-product gas generated from adsorption reaction.
