최근 들어 소프트웨어의 복잡도와 규모의 증가와 함께 테스트의 중요성 또한 증대되고 있다. 테스트는 QA(Quality Assurance) 기간에 한정되지 않고 개발 기간에 꾸준히 적용 되어 자주 수행될수록 높은 품질 향상을 기대할 수 있다. 하지만, 지금까지 대다수의 테스트는 QA과정에 국한 되어 반복적이고 비 능률적인 매뉴얼 테스트 방법을 위주로 진행 되고 있다. 이는 코드 변경에 대해 효과적으로 회귀 테스트(Regression Test)를 수행할 수 없음을 의미하며 결과적으로 테스트를 자주 수행할수록 비용이 급격하게 증가하는 문제점을 가지고 있다. 본 논문에서는 이러한 문제점을 극복하기 위한 테스트 자동화 프레임워크(Framework)를 제안하고자 한다. 제안된 테스트 프레임워크는 테스트 테이블을 바탕으로 테스트를 가시적으로 설계할 수 있는 기능을 제공하며 스크립트 및 코드 작성을 최소화하여 적은 비용으로 빠른 시간 안에 테스트 자동화를 구현할 수 있도록 도와준다.

Porphyromonas gingivalis is a gram-negative bacteria of rod shape, and grown in an anerobic condition. It colonizes in subgingival crevice and is known as a major pathogen causing chronic periodontitis. It possesses an invasive property and replicative potential within various cell types, presumably playing an important role in modulating biological behaviors of oral cancer. However, the pathophysiology of P. gingivalis in the malignant transformation of oral cancer has not been fully understood. In this study, we aimed to investigate molecular changes of oral squamous cell carcinoma cells induced by repetitive P. gingivalis infection that clinically resembles chronic periodontitis.

The majority of the Web's success can be related to its productivity and flexibility. Web Services (WSs) have the means to create new patterns for the delivery of software capabilities. The WS easily provides the use of existing components available via the Internet. WSs are a new trend that shares ubiquitous systems with others, so the popularity of the Web is increased day by day with their associated systems. This paper will explore and adopt the possibility of developing a technique that will automate instructors' scheduling of timetables within a Web services environment. This technique has an advantage that facilitates users to reduce the time cost and effort by reducing errors and costs for institutes. Providing dependable tables to avoid mistakes related to instituting schedules is ensured by an automated repetitive manual procedure. Automated systems are increasingly developed based on organizations and their customers. Still, the setting's difficulty of automation systems increases to rise as the system architecture and applications must accomplish various requirements and specifications of ever-demanding project scenarios. The automation system is composed of an operating system, platforms, devices, machines, control system, and information technology. This architecture provides more productivity and optimized services. The main purpose of this paper is to apply an automation system to enhance both quality and productivity. This paper also covers an agile method of proving an automation system by Finite State Machine (FSM) and Attributed Graph Grammar (AGG) tool.

The more repetitive, complex and objective the work, the more effective automation is. Code checking is an example of this. Checking building codes through a thick set of drawings is error-prone and time-consuming. In order to overcome this problem, several organizations have initiated efforts to automate building-code checking. Initiated study mainly focused on checking codes for invalidation, required size and crash, and then area of checkable codes have been expanding. But, it has not been considered for codes regarding anti-disaster/egress, which is also issued these days. This study is about how to automatically check codes for anti-disaster and egress based on Korea building codes. The codes can be categorized as five sections: egress way, material/capability, principals of evacuation, evacuation stairway and fire protection partition. To check automatically, there are problems, such as expression of codes for egress and limitation of extractable information from the BIM model. This paper shows what problems exist and assignments to be resolved. Also, current developing processes are presented, and suggestions are made about the direction for the work that remains.

Construction processes are highly repetitive. A resource entity continuously cycles through work tasks that processes or uses resources. Web-CYCLONE (Halpin 1992) has been accepted as a useful tool for modeling and analyzing a specific operation. However the system has a lack of practicality as follows: (1) it does not efficiently record and keep track of operation models in a database; (2) it does not provide the functions which facilitate to retrieve corresponding model and to update local variables of the model using observed data; (3) it does not automate the complex process that executes simulation experiment, analyzes simulation outputs and generates a report on behalf of the practitioners. Therefore, practitioners have a difficulty in reusing, modifying and analyzing the existing operation models. This study introduces a Client/Server based CYCLONE that improves above-mentioned limitations in the existing Web-CYCLONE. The system was illustrated by revising CSPU in practice.

All cancers are caused by abnormalities in DNA sequence. Throughout life, the DNA in human cells is exposed to mutagens and suffers mistakes in replication, resulting in progressive, subtle changes in the DNA sequence in each cell. Since the development of conventional and molecular cytogenetic methods to the analysis of chromosomal aberrations in cancers, more than 1,800 recurring chromosomal breakpoints have been identified. These breakpoints and regions of nonrandom copy number changes typically point to the location of genes involved in cancer initiation and progression. With the introduction of molecular cytogenetic methodologies based on fluorescence in situ hybridization (FISH), namely, comparative genomic hybridization (CGH) and multicolor FISH (m-FISH) in carcinomas become susceptible to analysis. Conventional CGH has been widely applied for the detection of genomic imbalances in tumor cells, and used normal metaphase chromosomes as targets for the mapping of copy number changes. However, this limits the mapping of such imbalances to the resolution limit of metaphase chromosomes (usually 10 to 20 Mb). Efforts to increase this resolution have led to the "new"concept of genomic DNA chip (1 to 2 Mb), whereby the chromosomal target is replaced with cloned DNA immobilized on such as glass slides. The resulting resolution then depends on the size of the immobilized DNA fragments. We have completed the first draft of its Korean Genome Project. The project proceeded by end sequencing inserts from a library of 96,768 bacterial artificial chromosomes (BACs) containing genomic DNA fragments from Korean ethnicity. The sequenced BAC ends were then compared to the Human Genome Project′s publicly available sequence database and aligned according to known cancer gene sequences. These BAC clones were biotinylated by nick translation, hybridized to cytogenetic preparations of metaphase cells, and detected with fluorescein-conjugated avidin. Only locations of unique or low-copy Portions of the clone are identified, because high-copy interspersed repetitive sequences in the probe were suppressed by the addition of unlabelled Cotl DNA. Banding patterns were produced using DAPI. By this means, every BAC fragment has been matched to its appropriate chromosomal location. We have placed 86 (156 BAC clones) cytogenetically defined landmarks to help with the characterization of known cancer genes. Microarray techniques would be applied in CGH by replacement of metaphase chromosome to arrayed BAC confirming in oncogene and tumor suppressor gene: and an array BAC clones from the collection is used to perform a genome-wide scan for segmental aneuploidy by array-CGH. Therefore, the genomic DNA chip (arrayed BAC) will be undoubtedly provide accurate diagnosis of deletions, duplication, insertions and rearrangements of genomic material related to various human phenotypes, including neoplasias. And our tumor markers based on genetic abnormalities of cancer would be identified and contribute to the screening of the stage of cancers and/or hereditary diseases

베단따의 주요 실천 방법인 '듣기 숙고하기 명상하기'(이하 '3수단'으로 부름)는 연속적인 단계(step)로서가 아니라 동일한 목적의 방편적 연장(extension)으로서 파악되어야 한다. 즉 3수단은 듣기에서 직접적 지식을 획득하지 못하는 경우에 방편적으로 숙고하기, 명상하기로 연장되어야 하는 것이라고 듣기 중심적인 방식으로 해석되어야 한다. 이러한 해석은 3수단이 암시하는 인도철학의 주요 특징들을 드러냄으로써 더욱 정당화될 수 있을 것이다. 인도철학에서 해탈 중심적 전통에 속하는 베단따는 쉽게 말해 자기를 앎으로써 자기가 되려고 하는 '본래의 자기 되찾기' 프로젝트이다. 이 경우 본래의 자기에 대한 지식을 얻기 위해서는 그것을 듣는 것만으로도 충분하기에, 3수단을 듣기 중심적으로 해석하는 것은 베단따의 근본 가르침과도 부합된다. 게다가 '본래의 자기 되찾기' 프로젝트는 3수단을 통해 실행되므로, 3수단은 베단따의 형이상학이라는 그 시나리오에 따라 실행되는 일종의 이벤트(event)라고 부를 수 있다. 이 경우 듣기란 자신이 참가한 이벤트의 시나리오를 이해하는 과정으로서, 스스로 더 효과적이라고 판단한 그 시나리오를 듣기만 해도 프로젝트의 완성에 도달할 수 있어야 한다. 그런데 성언이라는 지식수단의 중요성으로 말미암아 듣기 중심적일 수밖에 없는 3수단에 대해, 후대에 점점 명상하기가 강조됨으로써 연장이 아닌 단계로 이해하고자 하는 해석이 등장한다. 이는 '증언되는 것 혹은 주어진 것'을 '특별하게 지각되는 것 혹은 받아들이는 것'으로 만들고자 하는 욕망이 반영된 결과이다. 지식의 간접성과 직접성을 나눈 채 전자에서 후자로 단계적 이행을 강조하는 이 해석은, 프로젝트의 실질적 실패로서 이벤트의 반복적 지연을 합리화하려는 시도라고 볼 수 있다. 더 나아가 3수단에 삼매를 더하여 4수단을 언급하는 후대 베단따의 주장은 텍스트 바깥에서 텍스트와 별도로 깨달음이 가능하다는 논리를 바탕으로 하기 때문에, 텍스트의 절대성을 강조하면서 그 시나리오가 오직 그대로 재현되는 것을 깨달음으로 간주하는 초기 베단따의 주장과 양립하기 힘들다. 결국 3수단에 대한 베단따의 표준적 해석은 명상하기 중심적 혹은 삼매 중심적인 것이 아니라 듣기 중심적인 것이어야 한다.

Dual-color fluorescence in situ hybridization karyotype analysis was created using repetitive sequences including two types of rDNA repeats (45S and 5S rDNAs) and Arabidopsis-type telomere sequence repeats. The somatic metaphase cells of Carthamus tinctorius were observed as diploids (2n=2x=24). A symmetrical or slightly asymmetrical karyotype with seven pairs of metacentric and five pairs of submetacentric chromosomes was observed. The lengths of the somatic metaphase chromosomes ranged from 4.18 to $6.53{\mu}m$, with a total length of $60.71{\mu}m$. One locus of 45S rDNA was located on the pericentromeric regions of three pairs of chromosomes and the other pair was situated on the terminal regions of the short arms of a single pair of chromosomes. One locus of 5S rDNA was detected on the interstitial regions of the short arms of two pairs of chromosomes. Arabidopsis-type telomeric repeats were detected on the terminal regions of all pairs of chromosomes. Co-localization of loci between telomeric repeats and 45S rDNA was observed in a single pair of chromosomes. The results provide additional information for the existing physical mapping project of C. tinctorius and will also serve as a benchmark to a more intricate cytogenetic investigation of C. tinctorius and its related species.

We evaluated the efficacy of health education in reducing indoor arthropod allergens in Seoul. The mite control measures comprised the use of mite-proof mattress and pillow coverings, regular washing of potentially infested materials, maintenance of a low humidity, removal of carpets, and frequent vacuum cleaning. Cockroach control measures included trapping, application of insecticides, and protecting food. Of 201 homes enrolled in October 1999, 63 volunteers were included in a 2-year follow-up survey between April 2000 and January 2002. Before intervention, the density of mites/g of dust varied greatly; 27.1/g in children's bedding, 20/g in adult bedding, 7.2/g on the floors of children's bedrooms, 6.8/g in sofas, 5.9/g on the floors of adult's bedrooms, 3.9/g on living room floors, 3.7/g in carpets, and 1.9 mites/g on kitchen floors. The predominant mite species and house percentages infested were; Dermatophagoides farinae $93\%$, D. pteronyssinus $9\%$, and Tyrophagus putrescentiae $8\%$. Comparing 1999 and 2001 infestations, before and after 25 mo of education, mite abundance was reduced by $98\%$, from 23.7 to 0.57 mites/g of dust. In 1999, cockroaches were detected in $62\%$ homes: $36\%$ Blattella germanica and $35\%$ Periplaneta spp., including $9\%$ double infestations of B. germanica and P. americana. Following intervention, cockroach infestation rates decreased to $22\%$ of houses in 2000 and $23\%$ in 2001. We conclude that continuous and repetitive health education resulted in the effective control of domestic arthropods.
