Blockchain is a core technology to solve personal information leakage and data management issues, which are limitations of existing Genomic Sequencing services. Due to continuous cost reduction and deregulation, the market size of Genomic Sequencing has been increasing, also the potential of services is expected to increase when Blockchain's security and connectivity are combined. We created our research model by combining the Technology Acceptance Model (TAM) and the Innovation Resistance Theory also analyzed the factors affecting the acceptance intention and innovation resistance of the Blockchain Based Genomic Sequencing Information Platform. A survey was conducted on 150 potential users of Blockchain and Genomic Sequencing services. The analysis was conducted by setting the four Blockchain variables: Security, transparency, availability, and diversity). Also, we set the Perceived Usefulness, Perceived risk, and Perceived Complexity for Technology Acceptance and Innovation Resistance variables and analyzed the effect of the characteristics of the Blockchain on acceptance intention and innovation resistance through these variables. Through this analysis, key variables that need to be considered important to reduce resistance and increase acceptance intention could be identified. This study presents innovation factors that should be considered in companies preparing a new Blockchain Based Genomic Sequencing Information Platform.

This study aims to develop an evaluation method for solar power facilities considering disaster impacts and to analyse the vulnerabilities of existing facilities. Haenam-gun in Jeollanam-do, where the reassessment of existing facilities is urgent, was selected as the study area. To evaluate the vulnerability from a more objective perspective, principal component analysis and entropy methods were utilised. Seven vulnerability assessment indicators were selected: maximum hourly rainfall, maximum wind speed, number of typhoon occurrence days, number of rainfall days lasting more than five days, maximum daily rainfall, impermeable area ratio, and population density. Among these, maximum hourly rainfall, maximum wind speed, maximum daily rainfall, and number of rainfall days lasting more than five days were found to have the highest weights. The overlay of the derived weights showed that the southeastern regions of Haenam-eup and Bukil-myeon were classified as Grade 1 and 2, whereas the northern regions of Hwawon-myeon, Sani-myeon, and Munnae-myeon were classified as Grade 4 and 5, indicating differences in vulnerability. Of the 2,133 facilities evaluated, 91.1% were classified as Grade 3 or higher, indicating a generally favourable condition. However, there were more Grade 1 facilities than Grade 2, highlighting the need for countermeasures. This study is significant in that it evaluates solar power facilities considering urban disaster resilience and is expected to be used as a basic resource for the installation of new facilities or the management and operation of existing ones.

The ROK military is making a great effort and investment in establishing network-centric warfare, a future battlefield concept, as a major step in the establishment of a basic plan for military innovation. In the military organization level, an advanced process is introduced to shorten the command control time of the military and the business process is improved to shorten the decision time. In the information system dimension, an efficient resource management is achieved by establishing an automated command control system and a resource management information system by using the battle management information system. However, despite these efforts, we must evaluate the present level of informatization in an objective manner and assess the current progress toward the future goal of the military by using objective indicators. In promoting informatization, we must systematically identify the correct areas of improvement and identify policy directions to supplement in the future. Therefore, by analyzing preliminary research, workshops, and expert discussions on the major informatization level evaluation models at home and abroad, this study develops an evaluation model and several indicators that systematically reflect the characteristics of military organizations. The developed informatization level evaluation model is verified by conducting a feasibility test for the troops of the operation class or higher. We expect that this model will be able to objectively diagnose the level of informatization of the ROK military by putting budget and resources into the right place at the right time and to rapidly improve the vulnerability of the information sector.

In 1993, a large number of relics was found in Cheongju Sanesa Buddhist Temple. They show superiority as bronze-based products, and are especially important in since they provide much information about the time of their creation. However, there are many opinions about the time they were hoarded: in the middle of the 13^th century, late in the 13^th century, early in the 14^th century, etc. This study estimates the time they were hoarded to be some time in April 1291 during the invasion of Kădīn (哈丹) in the Yuan Dynasty. Kădīn's troops invaded the Goryeo Dynasty, then went through Yangpyeong and Wonju in January 1291 and appeared in Yeongi-hyeon on May 1 of that year. Based on records, this study verified that the troops passed through Cheongju on their way from Chungju to Yeongi-hyeon (currently Sejong-si) and pointed out that the invasion route of the troops was the background for the hoarding of Sanesa relics. The estimation that the Sanesa relics were hoarded in 1291 when Kădīn's invasion was going on makes it possible to reasonably clear up the era of the relics in which the Heavenly Stems called gānzhī (干支) Muo (戊午), Gyeongshin (庚申), Giyu(己酉) etc. were written. That is, Giyu Geumgo is presumed to be the year 1249, Muo Hyangro 1258, Gyeongshin Hyangwan 1260, etc.

This paper presents the results of an experimental study to evaluate the shear behavior of reinforced concrete beams reinforced with FRCM composites using different types of textile grids. It was found that the shear behavior of reinforced concrete beams with FRCM composites was observed by comparing the strains measured in the stirrups and textile grids. It was found that the ultimate strength of the strengthened specimens increased compared to the basic specimens, and the failure mode at ultimate strength changed from shear failure to bending failure. When the shear strength design values of the KDS 14 20 22 and AIJ ultimate strength types were compared with the actual experimental values, it was found that the AIJ ultimate strength type was more accurate. In addition, the shear contribution of FRCM composites in the A and T models was compared, and the results showed that both models had similar trends. Reflecting these results, it is recommended that further studies should be conducted to calculate the shear performance of beam members with FRCM composites and the shear contribution of FRCM composites by using the stirrup reinforcement ratio and the type of textile grid as variables.

The study examines the effects that non-audit service and firm's ownership structure might have on the value relevance directly or indirectly. This investigation is based on prior research which suggests that the audit firms' non-audit services is likely to adversely affect investors' perceptions of the credibility of financial reporting and that corporate governance are likely to mitigate the adverse this kind of non-audit services effects. The sample consists of non-banking firms listed on the Korea Exchange that reported annual financial statements over the period from 2004 to 2008. In the setting, stock returns as proxy for capital market response, auditor quality(measured as the discretionary accruals) is endogenously determined. This study employs a structural equation model to take into account the endogenous variables under study. The analysis influences through the path analysis that ownership structure suppress the market response through audit quality and also the non-audit service have influence on the market response through audit quality. The results of this study contribute to the literature in the following ways. First, this provides direct evidence that there is a negative association between audit firms' client importance and the value relevance. Second, the findings that the negative association is attenuated for audit quality support the findings of prior studies which present that corporate governance provide higher credibility of financial reports.

Nowadays to thrive on the intensively competitive environments based on drastic and rapid technical evolutions, exporting manufacturing companies need to keep very stable relationship with suppliers. Thus, analyzing key factors of strengthening relationship with suppliers in a B2B environment is important. In this regard, this study develops a research model to deeply understand key antecedents of relationship strength between B2B companies. Relationship quality was considered as the key factor affecting to the relationship strength. This study considers relationship satisfaction, trust, and relationship commitment as the factors of relationship quality. Moreover, technical service quality and relational service quality were considered to be the antecedents of relationship satisfaction, while communication and information exchange, relationship policies and practices, and opportunistic behavior were regarded as the antecedents of trust. The PLS method was applied for the empirical analysis of 107 companies data. The results indicated that the relationship commitment has a significant impact on relationship strength. Moreover, relationship satisfaction and trust had indirectly impact on relationship strength through relationship commitment. Although the quality of technical service quality had a significant impact on relationship satisfaction, relational service quality did not have a significant impact. While communication and information exchange, relationship policies, and practices had positively significant impacts, opportunistic behavior had a negative impact.

This study examines the impact of government funds to venture capital on investment in early-stage firms. We provide novel explanations about this relationship focusing on mechanisms by which government funds influence the perceived uncertainty, decision about investment priority, scale economy of investment, information asymmetry in investment decision, and capital expense. We argue that venture capital's investment in early-stage firms increases as government funds increase and as government funds are explicitly directed for early-stage firms. However, we further claim that the impact of government funds on early-stage investment will be decreasing as their size increases and finally be reverted to negative impact beyond a certain amount of funds to show inverse-U relationship. Our empirical examination using data from 105 Korean venture firms active as of 2013 consistently supports the claims. This study contributes to the venture capital literature by providing novel arguments about mechanisms and effects of policy intervention in venture capital. In practice, we expect our results will provide an opportunity for relevant policy makers to review their venture support policy based on empirical evidences for policy effects.
