Generally, a software development process is composed with requirements analysis, design, coding, test and maintenance. However, some changes of the design step are difficult to complicate the next step in the development process. It always causes the disagreement between design and implementation step. In this paper, we have developed a tool which can generate an application program. The tool can reduce the disagreement between system design and implementation and recognize the business logic to develop the software rapidly and flexibly In addition, we proposed a non-program-based application program system approach was proposed, In. We can generate and modify an application program with this method which can edit the meta data of a system design by the dynamic method for the execution time.

Software development process consists of five phases : requirement, analysis, design, implementation and testing. There is almost always a gap between the system design and implementation stages, caused by a combination of the difficulty of programming and frequent changes on the system design. The goal of this paper is to reduce the gap between system design and implementation, and we design a tool producing a application program by recognizing business logic for a more rapid and flexible developing of software. The core idea of Application Program Generator is : firstly, to recognize that business application in the same domain share business logic and presentation logic : secondly, to treat system design as persistent meta-data ; thirdly, to use the persistent meta-data to build or customize applications as required.

Prostate cancer is a leading cause of death in male populations across the globe. With the advent of gene expression arrays, many microarray studies have been conducted in prostate cancer, but the results have varied across different studies. To better understand the genetic and biologic mechanisms of prostate cancer, we conducted a meta-analysis of two studies on prostate cancer. Eight key genes were identified to be differentially expressed with progression. After gene co-expression analysis based on data from the GEO database, we obtained a co-expressed gene list which included 725 genes. Gene Ontology analysis revealed that these genes are involved in actin filament-based processes, locomotion and cell morphogenesis. Further analysis of the gene list should provide important clues for developing new prognostic markers and therapeutic targets.

현재까지의 EDB 시스템이 Data를 중심으로 한 관리나 프로세스 관리 같은 것들을 프로그램으로는 Hard Coding되어 있었던 관계로 인하여 단위업무의 성력화 또는 순수 데이터 관리 측면에서는 효율성을 가졌으나, 기업의 무한경쟁시대에 생존 수간으로서 행해지고 있는 BPR(Business Process Restructure) 또는 CE(Concurrent Engineering)에 대응 할 수 있는 유연성이 결여되어 있었다. 따라서 프로세스나 데이터에 관련된 규칙 또는 데이터가 있는 위치등과 같은 프로세스 및 데이터의 속성에 대한 정보를 Meta Database에 저장하여 보다 유연성이 있고 일관성 있게 데이터를 취급해 줄 필요성이 대두 되었다. 이러한 Meta Database를 사용자 시각에서 바라보면 프로세스가 변화 된다하더라도 일관된 실제 작업을 할 수 있을 것이다. 즉, 사용자는 자신이 사용하는 EDB의 단위 Application을 사용하면 새로 정의된 프로세스에 따라 자신의 데이터를 Release하고 시방변경, 삭제, 의뢰 등을 처리 할 수 있을 것이다. 따라서 현재의 EDB 시스템들의 개발이 전체의 개발 프로세스 중에서 일부만을 부분부문으로 개발하고 통합 할 뿐 실제 일관된 데이터의 유지나 공유가 매우 힘들었던 것을 부분적인 형태로 시스템이 구축된다하더라도 Meta Database를 통하여 개발 프로세스 전반에 걸친 다양한 PART 시스템간의 데이터 공유를 가능하게 할 수 있는 EDB 시스템구조에 대해 설명하고자 한다.

The FAT (File Allocation Table) compatible file system has been widely used in mobile devices and memory cards because of its data exchangeability among numerous platforms recognizing the FAT file system. By the way. modern embedded systems have tough demands for instant power failure recovery and superior performance for multimedia applications. The key issue is how to achieve the goals of superior write performance and instant booting capability while controlling compatibility issues. To achieve the goals while controlling compatibility issues. we devised a temporary meta-data journaling scheme for a FAT compatible file system. Benchmark results of the scheme implemented in a FAT compatible file system shows that it really improves write performance of the FAT file system by converting small random write for meta-data update to a large sequential write in journaling area. Also, it provides natural way to implement the instant booting capability. Nevertheless, the file system compatibility is temporarily compromised by the scheme because it stores updated meta-data in the temporary journaling area rather than to their original locations. However, the compatibility can be fully recovered at any time by journal-flushing that copies meta-data in journaling area to their original locations. Generally, the journal-flushing is done before un-mounting a memory card so that it can be used in other mobile devices which recognized FAT file system but not the temporary meta-data journaling scheme.

We introduce a high-performance named entity recognition (NER) model for written and spoken language. To overcome challenges related to labeled data scarcity and domain shifts, we use transfer learning to leverage our previously developed KorBERT as the base model. We also adopt a meta-pseudo-label method using a teacher/student framework with labeled and unlabeled data. Our model presents two modifications. First, the student model is updated with an average loss from both human- and pseudo-labeled data. Second, the influence of noisy pseudo-labeled data is mitigated by considering feedback scores and updating the teacher model only when below a threshold (0.0005). We achieve the target NER performance in the spoken language domain and improve that in the written language domain by proposing a straightforward rollback method that reverts to the best model based on scarce human-labeled data. Further improvement is achieved by adjusting the label vector weights in the named entity dictionary.

Recently, XML has been widely used as a standard for a data exchange, and there has emerged the tendency that the size of XML document becomes larger. The data transfer can cause problems due to the increase in traffic, especially when a massive data such as Data Warehouse is being collected and analyzed. Therefore, an XMDR wrapper can solve this problem since it analyzes the tree structures of XML Schema, regenerates XML Schema using the analyzed tree structures, and sends it to each station with an XMDR Query. XML documents which are returned as an outcome encode XML tags according to XML Schema, and send standardized messages. As the formalized XML documents decrease network traffic and comprise XML class information, they are efficient for extraction, conversion, and alignment of data. In addition, they are efficient for the conversion process through XSLT, too, as they have standardized forms. In this paper we profuse a method in which XML Schema and XMDR_Query sent to each station are generated through XMDR(extended Meta-Data Registry) and the generation of products and XML conversion occur in each station wrapper.

W3C enacted RDF(Resource Description Framework based DCAT meta data standard, which is world-widely accepted so far. To guarantee the inter-operability and integrity of data from various sources and even from various countries, it is considered that transportation meta data should also follow the DCAT standard. But still, to represent the transportation domain-specific features, it is necessary to define new properties and vocabularies in addition to the DCAT standard. This research identified the additional properties and vocabularies for transportation metadata, considering uniqueness of transportation data. The revised RDF schema and RDF graph proposed in this research should be able to lead the transportation open data platform revitalization.

The purpose of this study is to identify the trends of emotion-related mathematics education research conducted in Korea so far, and compare them with those of international studies, and explore the desirable directions for future emotion-related mathematics education research. Emotion-related domestic research was collected from domestic academic journals, analyzed, and then it was used as data for international comparative study. The findings of the Eligio(2017) were used as counterpart research data. This study compares the number of publications, research subjects and research topics of domestic and international studies on emotion. Findings indicate that it has generally shown similar patterns to international research although it was difficult to determine the trends due to the lack of the number of domestic studies. The future directions of domestic mathematics education research on emotion were proposed as follows. Since it is difficult to collect reasonable and reliable data on pure emotion due to the nature of emotion in mathematics education research, it is suggested to introduce the concept of emotional intelligence, which is the combination of emotion and cognition. Also, it was recommended to utilize the concept of meta-emotion for future study on emotion-related research.
