The purposes of this study were to develop the computer program for the contrast and geometric correction in digital subtration radiography with the IDL (Interactive Data Language) and compare the results with this program for the correction of the non-standardized radiographs to those of standardized radiographs and those with "Emago" software, the commercial program for the correction. The procedures were written for the contrast correction and subtraction with the geometric correction, using IDL. 32 pairs of periapical radiographs of premolar and molar portion of two dry human mandibles were taken at two different occasions with XCP film holder(nonstandardized films) and another 32 pairs with customized XCP film holder(standardized films). Subtraction of standardized film pairs was performed. Subtraction after the contrast and geometric correction of non-standardized films was performed using the newly developed program and Emago software. Standard deviations of grey levels of the subtracted images by the newly developed program were compared with those of the standardized group and Emago-corrected group. Standard deviations of grey levels of new program-corrected group were much smaller than those of the Emago-corrected group (p<0.001) and slightly larger than those of standardized group (p<0.05). However, the difference was very minute. This study indicates that the newly developed program written with IDL may substitute the mechanical standardization for digital subtraction radiography.

최근 세계 자동차 업계는 AUTOSAR 소프트웨어 플랫폼 표준을 제정하여 소프트웨어의 신뢰성과 재사용성을 향상키고 있다. 그러나 테스트 시스템 및 테스트 프로세스의 신뢰성 확보와 테스트에 소요되는 기간 단축을 위하여 테스트의 표준화 및 자동화가 절실하다. 특히 RTE 및 베이직 소프트웨어 모듈은 표준화를 만족하는 설계 도구를 사용함으로써 최소한의 신뢰성이 보장되지만, 여전히 응용 소프트웨어 컴포넌트에 대해서는 철저한 테스트가 필요하다. 본 논문에서는 표준화된 AUTOSAR 설계 정보를 이용하여 소프트웨어 컴포넌트의 유닛 테스트를 위한 테스트 시스템의 생성 및 테스트 케이스 생성 자동화 방법을 제안하였으며, 테스트 시스템은 TTCN-3 테스트 표준을 적용하였다. 본 논문에서 제안한 방법을 적용함으로써 차량 소프트웨어의 개발 기간 단축 및 신뢰성을 향상시킬 수 있었다.

In architecture projects, BIM library has widely been using for prefabrication of products and design process. However, since the shape of structures is different by each project in civil engineering projects and a shape representation system is complicated, it is not easy to develop a standardized BIM library. To solve these issues, this study develops BIM library based on standardized 2D shop drawings for civil structures. The standardized shop drawings, which are the targets of the BIM library model, should be first selected. Besides, in order to define modeling scope with the level of general and shop drawings for each structure, LOD(Level of Detail) and breakdown structure are determined, and development methods of families of 3D object type including 2D profile and rebar through commercial software are established. With these, properties of BIM library are configured, and a utilization model of the BIM libraries is constructed for 3D modeling and a simulation using the BIM library. Therefore, this study can identify properties that are necessary when IFC schema is configured for civil engineering projects. For future, it is expected that easiness of BIM design for the civil engineering projects and generation, management, and analysis system of BIM library for road projects will be secured.

Since software development team members have been more geographically spread due to the globalization of business and Internet technologies, the management of deliverables and communication efforts for developing high-quality software products on time is becoming more complicated. Among the functional requirements for collaborative software development management, the manipulation of shared information objects is essential for the collaborative work among distributed development team members. This paper proposes an integrated information object management framework comprised of a so-called BOC (Bill Of Class) scheme and a standardized software part dictionary for managing shared information objects efficiently among distributed co-workers. In order to manage these complex information objects, the proposed framework adopt product structures represented by Bills Of Materials (BOM) as stems for integrating the various information objects. Based on the proposed framework, a collaborative software development management system (CSDMS) is implemented, and the functionalities and the structure of the system are also described in this paper. The proposed system provides sufficient functionalities for the change management of information objects and the management of their relationship to other objects rather than existing system.

Recently a standard software platform for automotive, AUTOSAR, has been developed to manage growing software complexity and improve software reuseability. However reuse of testing system and test data are difficult because they are dependant on implementation language and testing phases. In this paper, we suggest a automated testing approach for AUTOSAR software component using a standardized testing language, TTCN-3. AUTOSAR defines the AUTOSAR XML Schema for the data exchange format so that it is possible to automatically convert AUTOSAR model into TTCN-3 testing model. Therefore our approach is to present generation techniques for the TTCN-3 testing system from a AUTOSAR XML description. With the proposed testing techniques we can reduce time and effort to build the testing system and reuse testing environment.

Backgrounds: Patient counseling has been forced since June. 19, 2014. Prior to this, there was no study to try to standardize medication counseling to improve quality. Purpose: This study was to investigate satisfaction level and comprehension level between the pharmacist group and the patient group about standardized medication counseling sheet. Methods: Questionnaires to assess standardized patient counseling sheet were posted at online survey software (Qualtrics) to pharmacists who worked at community pharmacy and patients who had visited community pharmacy before. Results: Three hundred thirty five patients and three hundred nineteen pharmacists were responded to the questionnaire (Response rate: 72.9%). More than half of each group were satisfied with standardized medication counseling sheets 'for the general public', 'for the pregnant women and nursing mothers', 'for the chronic patient', and 'for the aged' and patient group were more satisfied than pharmacist group. Similarly, more than half of each group comprehended with the medication counseling sheets 'for the general public', 'for the pregnant women and nursing mothers', 'for the chronic patient', and 'for the aged'. Patient group tended to expect longer patient counseling time per one drug than pharmacist group. Also, the majority of both groups wanted to provide standardized medication counseling sheets constantly and extend for all drugs. Conclusion: Both groups were satisfied and comprehended standardized medication counseling sheets, and agreed to expand standardized medication counseling sheets to all drugs. So, it is necessary to build the standardized medication counseling of all drugs.

Background: Testicular cancer is one of the most common cancers among young men between ages 20-34 in countries with high or very high levels of the Human Development Index (HDI). This study investigated the incidence and mortality of prostate cancer and the relationship with the HDI and its dimensions in Asia in 2012. Materials and Methods: The study was conducted based on data from the world data of cancer and the World Bank (including the HDI and its components). Standardized incidence and mortality rates of testicular cancer were calculated for Asian countries. Correlations between incidence and/ormortality rates, and the HDI and its components were assessed with the use of the correlation test, using SPSS software. Results: There was a total of 14902 incidences and 5832 death were recorded in Asian countries in 2012. Among the Asian countries, the five countries with the highest standardized incidence rates of testicular cancer were Israel, Georgia, Turkey, Lebanon and Kazakhstan and the five countries with the highest standardized mortality rates were Turkey, Georgia, Jordan, Cambodia and the Syrian Arab Republic. A positive correlation of 0.382 was observed between the standardized incidence rates of testicular cancer and the HDI (p=0.009). Also a negative correlation of 0.298 between the standardized mortality rate of testicular cancer and the Human Development Index was noted although this relation was statistically non-significant (p=0.052). Conclusions: There is a positive correlation between HDI and the standardized incidence rate of testicular cancer and negative correlation with standardized mortality rate.
