Recently Korean textile industry has been in the phase that requires its strategy change from the less-develped country style of the labor-intensive products to the developed country style of the technology-intensive products. It needs to make more efforts to develop the value-added products to meet the customer's various needs. In addition, development of technology, equipment, and design is required to implement its corporate strategy successfully. Although Korean textile companies have currently kept skillful labor and advanced equipments, they are losing their share in the international textile markets. This is mainly because corporate management has not been involved with efficient strategy. Strategy is an adoption of a company to environment by its corporate members, thus leading to the requirement of coordination of the main functions such as manufacturing and marketing. In fact, the coordination of the two departments toward reaching the corporate goal is not easy since the two are interested in different areas, respectively. Manufacturing people show their interests in production capacity, equipment layout, process technology, quality, purchasing, and labor while marketing people, target customer, product mix, advertisement, product specification, and customer service. For this reason, conflicts sometimes happen between the two departments. There are, however, many area that need a horizontal cooperation, for instance, in layout, process technology, product mix, and potential demand. Therefore, reciprocal coordination is necessary for achieving the firm's common objectives. This study was concerned with determining the factors that enhance the competitiveness of textile firms so that they could reach the common goal of the two departments with a horizontal collaboration.

In the era of the fourth industrial revolution, many production plants are gradually evolving into smart factories that apply information and communication technology to manufacturing, distribution, production, and quality management. The conversion from conventional factories to smart factories has resulted in the automation of production sites using the internet and the internet of things (IoT) technology. Thus, labor-intensive production can easily collect necessary information. However, implementing a smart factory required a significant amount of time, effort, and money. In particular, labor-intensive production industries are not automated, and productivity is determined by human skill. A representative industry of such industries is sewing the industry. In the sewing industry, wherein productivity is determined by the operator's skills. This study suggests that production performance, inventory management and product delivery of the sewing industries can be managed efficiently with existing production method by using smart buttons incorporating IoT functions, without using automated machinery.

Digital twins between "BIM Digital Model-Physical Prototype Model" will be built for Noise Barrier tunnel(NBT) that meet the definition of N.G smart city facilities derived from previous studies to build a data flow that connects data at each stage of design, construction, and operation. In this process, BIM design automation tools are created and utilized, and consistent transmission of member and attribute data is performed by converting them into IFC format. Through this, the purpose is to improve the labor-intensive environment required from the design stage of the NBT and to consistently maintain the information required for subsequent production and construction. This includes achieving changes in the construction industry based on digital transformation by unifying various data formats used differently for each industry from design to operation. In addition, it demonstrates that information exchange in the maintenance and management stages is possible based on the data exchange of the established digital twin and aims to improve the existing labor-intensive environment and expand operability between digital and physical information. As suggested in previous studies, the implementation of digital twins in these N.G smart city facilities includes the possibility of building an environment that adds to the possibility of high value-added product platforms as well as the function of big data platforms targeting existing smart cities.

Background: Single nucleotide polymorphisms (SNPs) are widely used genetic markers with applications in human disease diagnostics, animal breeding, and evolutionary studies, but existing genotyping methods can be labor-intensive and costly. The aim of this study is to develop a simple and rapid method for identification of a single nucleotide change. Methods: A modified Polymerase Chain Reaction Amplification of Multiple Specific Alleles (PAMSA) and high resolution melt (HRM) analysis was performed to discriminate a bovine polymorphism in the NCAPG gene (rs109570900, 1326T > G). Results: The inclusion of tails in the primers enabled allele discrimination based on PCR product lengths, detected through agarose gel electrophoresis, successfully determining various genotypes, albeit with some time and labor intensity due to the use of relatively costly high-resolution agarose gels. Additionally, high-resolution melt (HRM) analysis with tailed primers effectively distinguished the GG genotype from the TT genotype in bovine muscle cell lines, offering a reliable way to distinguish SNP polymorphisms without the need for time-consuming AS-PCR. Conclusions: Our experiments demonstrated the importance of incorporating unique mismatched bases in the allele-specific primers to prevent cross-amplification by fragmented primers. This efficient and cost-effective method, as presented here, enables genotyping laboratories to analyze SNPs using standard real-time PCR.

본 연구에서는 Hummels and Klenow (2005)의 분석방식을 이용하여 1990년대 이후 우리나라의 대중국 수출에 있어서의 수출의 다양도 및 집약도의 상대적인 기여도를 고찰하고 있다. 본 연구에서 수출 다양도란 우리나라를 제외한 대중국 전체 수출국의 수출품목 대비 우리나라의 대중국 수출품목의 비중을 의미한다. 한편, 수출 집약도는 우리나라의 대중국 수출품목 기준으로 우리나라를 제외한 대중국 전체 수출국 대비 우리나라 수출의 비중으로 정의한다. 분석 결과에 의하면, 최근 1990년대 이후 우리나라의 대중국 수출 확대의 주요인은 수출 집약도의 증가였던 것으로 나타난다. 이러한 결과는 중장기적인 수출 호조세의 지속을 위해서는 수출 다양도보다는 수출 집약도가 더 중요한 요인이라는 $Besede{\check{s}}$ and Prusa(2007), Helpman, Melitz, and Rubinstein(2007) 등의 분석과 일치된 결과이다. 수출 다양도의 경우, 무역자유화 초기에 해당되는 1990년대 초반에는 빠르게 증가하나 이후에는 부품 및 자본재 등 일부 품목을 제외하고는 오히려 다소 하락하는 추세를 나타냈다. 한편, 부품과 자본재가 전반적으로 1차 산품, 소비재 등 여타 상품군들에 비해 수출의 지속성(survival)이 높은 것으로 나타난다. 1차 산품, 소비재 등의 경우 수출 개시 후 4년 이내에 전체의 약 75% 수준의 품목이 수출을 중단하는 것으로 분석된 반면, 부품과 자본재는 기술 수준의 구분 없이 1992~2007년 기간 중 지속적으로 수출이 이루어진 품목의 비중이 15% 수준에 이른다. 이러한 분석 결과는 국제분업구조의 진전이 수출의 지속성에 지대한 영향을 미칠 수 있음을 시사한다.
