As global competition is more intensive, SCM is becoming more and more important in order to achieve competitiveness. It is necessary for firms to understand weak points among the integrated supply chain through supply chain assessment in order to implement SCM successfully and cost-effectively. In this paper, we review previous studies of SCM performance measurements and propose a supply chain assessment framework for shipbuilding industry, which is one of the major ETO industry. Based on 3 supply chain domains which are demand, supply, and product management, we decompose the whole supply chain process into 3 level lower processes and propose capability measurement matric for shipbuilding firms. A case study has been conducted to validate the proposed framework and results are presented at the end.

It is requested interoperability and inter-connection among technologies due to inertia and network externalities in the telecommunications industry. for that reason, firms in the telecommunications industry compete intensively against preempting their markets. Consumers' utilties can be increased, but searching or transaction cost of consumers may be decreased by standardization which is the core issue in the telecommunications. Also, standardization may prevent firms in that industry from overplus investment. However standardization may decrease the diversity of goods and technologies, so it can be the constraint factor in the consumption. In this paper, we'll examin the economic effects of standardization in the telecommunication industry and the effects to the industrial structure of standardization. After that, we'll suggest national policies in relation to standardization.

Soybean (Glycine max), as one of the foods with high plant proteins, contains a large amount of bioactive compounds and known to be effective in cardiovascular disease and obesity as well as in improving skin condition. The purpose of this study was to investigate the anti-photoaging effects of soybean fermented with Lactobacillus Rhamnosus ($Bio-Peptone^{(R)}$) by assessment of cytotoxicity against UVB, collagen synthesis after UVB-irradiation, tyrosinase activity, and melanin synthesis. Results showed that $Bio-Peptone^{(R)}$ protected skin fibroblasts against UVB-induced cytotoxicity and increased type I collagen synthesis. Furthermore, $Bio-Peptone^{(R)}$ significantly inhibited tyrosinase activity and reduced melanin contents. This study suggests that $Bio-Peptone^{(R)}$ has protective effects against UVB-induced skin damage. Thus, it is concluded that $Bio-Peptone^{(R)}$ is able to prevent skin damage against UVB and thus acts as anti-photoaging materials by protecting skin forming wrinkles and skin pigments.

We posit that employee ownership through defined contribution (DC) plans results in managerial entrenchment, and then examine the effect of the enactment of the Pension Protection Act of 2006 on the relation between the employee ownership and firm performance. By conducting Ordinary Least Square regression with the data from Form 5500 over the period of 1999-2014, we find that firms with large employee ownership increase their firm value measured by Tobin's Q after the adoption of the Act. These findings suggest that the adoption of the Act has been effective to mitigate the negative effect of managerial entrenchment by decreasing the employee ownership and reinforcing the fiduciary duty of plan trustees. Given the fact that we test the effects of the diversification rule on employee ownership using firm performance, further research could aim to examine the effects of the rule on employee ownership using stock return or market reaction.

We examine the relationship between abusive supervision and work-family conflict, and the moderating effects of employee's resilience and perceived organizational support. We collected the employees' sample(n=136) and conducted multiple hierarchical regression analysis. Abusive supervision has a significant positive effect on work-family conflict. Subordinate's resilience has a buffer effect on the main relationship, but perceived organizational support has no significant moderating effect. This study will be helpful for employees who are suffered from work-family conflict.

As the COVID-19 pandemic is prolonged, non-contact work has increased, as well as the demand for automation of simple and repetitive questions and tasks with success of using them. Therefore, companies are attempting to expand the area of automated business and apply various technologies such as AI to complex and various business processes of E2E to provide automation of all business. However, the extension to Intelligent Process Automation (IPA) is still in its beginning stage so that it is difficult to find practical use cases and related solutions. In this aspect, it is safe to say that there is insufficient evidence for companies which have various and complex enterprise processes to make a decision about the adoption. In this study, to solve this problem, a Hyper Automation Platform (HAP) that consists of RPA, Chatbot, and AI technology was proposed. Moreover, an implementation method that can bring intelligent process automation using HAP, and practical use-cases were provided so that it makes it possible to review the implementation of the HAP objectively and comprehensively. This study is meaningful and valuable to check the feasibility of the Hyper Automation concept and to actively utilize HAP.

While Korean GAAP had detailed regulations for the measurement and disclosure of operating income in the past, K-IFRS did not provide specific rules for operating income until 2011. Some firms that adopted K-IFRS before 2011 did not disclose or calculated operating income in an inconsistent manner although operating income is usually considered as one of the core information items to assess firm valuation. Inconsistency in firms' treatment of operating income invoked much criticism from diverse users of financial statement. The Korean Accounting Institute (KAI hereafter) revised the K-IFRS rules relevant to operating income in September 2010 in response to the voices raised by the business community, whereby the operating income number is allowed to be calculated in conformity with the previous K-GAAP. This study was motivated by the revision of K-IFRS and aims to provide a clue on the validity of such policy decision. To achieve the research objective, we test the relative value relevance of the alternative operating income numbers under K-IFRS versus K-GAAP. Our main findings are as follows. The value relevance of operating income reported before K-IFRS is proved to be higher than after K-IFRS. K-IFRS operating income adjusted to the previous K-GAAP has greater explanatory power for market values relative to one calculated under the K-IFRS regime. In an additional analysis, the sample was decomposed according to whether the operating income under K-IFRS is greater than under K-GAAP. The difference in the value relevance of K-IFRS versus K-GAAP operating income is significant only in the subsample consisting of firms which reports higher operating income under K-IFRS compared to K-GAAP. Also, the firms which would have reported negative operating income on a consecutive basis are more likely to have chosen K-IFRS, resulting in higher numbers than otherwise. It is likely that firms facing the threat of delisting due to consecutive operating loss reporting are more likely to have adopted K-IFRS disclosure rules by which they could report higher operating income numbers. To sum up, these results corroborate the limitation inherent in the K-IFRS regarding operating income disclosures. This paper suggests that the recent revision of K-IFRS implemented by KAI is likely to mitigate some of afore-mentioned limitations effectively.

Since 1997 the United Kingdom has pursued creative industry and creative city development in accordance with the New Labor Party policy, strengthening its cluster policy by assigning creative city policies to traditional manufacturing-oriented regions. Tech City in London, one of the most successful examples of digital clusters, is an area in which diverse ecosystems for venture business integration have been established, as the once barren space began to spontaneously develop. For this region, systematic linkages including universities, private companies, start-ups, and accelerators have been added, along with the UK government's active support system. As a result of this opportunity, the scale of the UK start-up ecosystem has significantly grown, the number of local companies has surged, and brand effect has greatly improved. Tech City is an example of a well-balanced combination of public effort and private governance, based on the region's historical background and its potential for growth. It is an effective coordination of public policy and private active investment, services, research, and education. The market platform for institutional technology and commercialization, and aggressive investment shares in the risk, have lead to its growth as a start-up and an innovative city. Britain's efforts to expand the nationwide cluster for the future-oriented digital economy is most noteworthy.
