Since the middle of 1990's, domestic apartment building suppliers have set up brand images to overcome the difficulties in financial situation after IMF foreign exchange crisis. The main trends in recent apartment buildings could be classified generally into several types, such as 'Ubiquitous Intelligent(standing for High-tech)', 'Walkable Community(community-friendly)', 'Eco-friendly', 'Ergonomic Humanity(Human Engineering)', 'e-easy Home through Internet(Digital Home)'. With those brand images, construction enterprises have been making inroads into local apartment markets, especially one of the region around Dae-gu. It is meaningful and worth researching and analyzing the local residents' preferences and tendencies to form marketing strategies of brand images. Here, this research and analysis is of pre-examination before getting down the study of this subject.

The rapid development of information media in the 21th century has given rise to the acceleration of fashion change and its diversification due to individual lifestyle, the personification and differentiation of consumers. This has got away from the function-centeredness of clothing and awakened people to the important task of hi-tech new materials development and design development. We immediately need to develop the measure to cope quickly and properly with changes in the dwindled fabric market. Consumers; needs are personified and diversified and the cycle of fashion materials become curtailed. From this perspective, this study attempted to manufacture the material for capable of satisfying consumers; psychology and needs with the handicraft based on the multi-item and small-quantity production system. This study attempted to present the possibility of differentiating products and developing diverse materials by applying the Woolsmok technique. It is expected that the development of these materials will not simply stay at the level of handicraft but contribute to the competitive materials of creativity and aesthetics by inducing it to be applicable to the industrial world and activate them as differentiated high-grade clothing materials for consumers at home and abroad.

Purpose - This study investigates the effects of going public on the innovation of KOSDAQ firms. Design/methodology/approach - This study uses firms that go public from 2007 to 2011 in Korea. We compare a firm's innovation performance over five years before and after IPO. Findings - We find that firm's innovation declines after an IPO. After going public, both the quality and the quantity of patents are decreased. However, this decrease is alleviated in high-tech industries or concentrated industries where innovation is expected to be more valuable. When comparing firms with venture capital(VC), which are more likely to window dress, to firms without VC, VC backing has no meaningful impact on changes of innovation. Research implications or Originality - As the KOSDAQ market was established to provide small and medium enterprises(SMEs) with funds for firm's investments and growth, it is necessary to verify whether the capital raised at the IPO encourages innovation. Thus, our study contributes to the literature by examining empirically whether an IPO boosts a firm's innovation.

소재와 부품은 제조업의 허리 역할을 담당한다. 2018년 우리나라의 소재부품산업의 수출액은 3,162억 달러로 2018년 기준 전체 수출의 52.3%를 차지할 정도로 급성장해 효자산업이 되었다. 이처럼 소재부품산업은 무역흑자를 이끄는 핵심산업이지만 유독 일본과의 관계를 보면 다른 모습을 보인다. 작년 대일무역적자는 240억 달러로 줄었으나 그중 소재부품산업의 적자는 151억 달러로 여전히 60%를 넘는 수준이다. 오늘날 일본이 첨단 소재부품산업에서 최고의 경쟁력을 가지게 된 것은 요인으로는 기업 간의 협력과 공생, 모노쯔쿠리 정신, 장기적인 정부정책 등에서 찾을 수 있다. 우리 경제가 일본의 첨단소재부품산업을 추격하기 위해서는 다음과 같은 인식전환이 필요할 것이다. 첫째, 소재부품산업은 동반성장을 전제로 하며 상생협력이 절대적으로 필요한 동반성장산업의 하나라고 할 수 있다. 일반적으로 소재와 부품은 최종제품이 아니라 중간제품이다. 따라서 소재와 부품은 소비자와 거래가 이루어지는 것이 아니라 기업 간의 거래만 이루어지는 특성을 잘 이해해야 한다. 둘째, 공동기술개발의 확대가 절대적으로 필요하다. 우리나라는 범용 소재부품산업분야에서는 경쟁력을 가진 기술강국이다. 그러나 자세히 살펴보면 중소기업의 기술개발 단계에서 대기업의 참여가 부진해 첨단제품의 개발이 상대적으로 어려운 구조를 가진 것으로 조사되고 있다. 우리나라 소재부품산업은 기술개발단계에서부터 대기업이 참여하여 고객의 다양한 의견을 전달하고 공동 R&D에 참여해야 할 것이다. 셋째, 장기적인 접근이 필요하다. 소재부품산업에서 대일 무역적자의 고착화는 첨단 기술 부족 등 우리나라 소재부품산업의 구조적 취약성이 직접적인 원인이지만 그 배경에는 기술에 대한 문화적 차이가 존재하기 때문이다. 우리가 첨단소재부품산업 분야에서도 경쟁력을 확보하기 위해서는 시간이 걸리더라도 기술과 노하우를 하나씩 쌓아가는 장기적인 접근이 절대적으로 필요하다. 여기에는 기업의 접근뿐만 아니라 정부의 정책도 마찬가지일 것이다.

Purpose - This study investigates whether the internationalization process of traditional industry firms can be categorized as born global, early internationalization, or gradual internationalization, and examines what factors promote internationalization in traditional industries using a case study of two firms, one each in China and Korea. Design/methodology - This study elects to use case study methodology to determine the "how" and "why" of internationalization process of traditional industry firms. Taking into consideration that factors that impact the internationalization process of firms are diverse and unclear in terms of causality, this study utilizes exploratory case study methodology. This research performs a comparative two-case study of two firms in traditional industries, one each in China and Korea, to examine similarities and differences of study subjects in order to improve the validity and suitability of research results. Findings - The findings of this research are as follows: First, traditional industries are more likely go through early and rapid internationalization rather than being born global; born globals are far more likely to appear in high tech industries. Second, the internationalization process of companies that go through early and rapid internationalization differs from what is indicated by traditional internationalization theories, and are not limited by factors like psychological distance and lack of experiential knowledge. Third, international entrepreneurship, international market orientation, and imitation and learning are important internal driving factors for early and rapid internationalization. Fourth, conditions within the domestic market, policy support from the government, and pilot effect from industry leaders are external driving factors for early and rapid internationalization. Originality/value - This study shows that the internationalization process of traditional industry firms is more likely to be early and rapid internationalization rather than being born global and suggests answers to why this may be the case. In addition, through an examination of case studies, it reveals that the internationalization process of traditional industry firms that undergo early and rapid internationalization is different from traditional internationalization theory, in that they are not limited by the lack of psychological proximity and empirical knowledge, and are driven by international entrepreneurship, international market orientation, imitation and learning, competitive pressure within the domestic market, government's policy support, and the pilot effect of industry leaders. Therefore, this study contributes to literature by expanding the scope of application of born global theory to traditional industries, making born global theory more generalizable and identifying driving factors to internationalization of traditional industry firms.

Currently, Illumina sequencers are the globally leading sequencing platform in the next-generation sequencing market. Recently, MGI Tech launched a series of new sequencers, including the MGISEQ-2000, which promise to deliver high-quality sequencing data faster and at lower prices than Illumina's sequencers. In this study, we compared the performance of two major sequencers (MGISEQ-2000 and HiSeq 4000) to test whether the MGISEQ-2000 sequencer delivers high-quality sequence data as suggested. We performed RNA sequencing of four human colon cancer samples with the two platforms, and compared the sequencing quality and expression values. The data produced from the MGISEQ-2000 and HiSeq 4000 showed high concordance, with Pearson correlation coefficients ranging from 0.98 to 0.99. Various quality control (QC) analyses showed that the MGISEQ-2000 data fulfilled the required QC measures. Our study suggests that the performance of the MGISEQ-2000 is comparable to that of the HiSeq 4000 and that the MGISEQ-2000 can be a useful platform for sequencing.
