  • This paper describes a reset-free delay-locked loop (DLL) for a memory controller application, with the aid of a hysteresis coarse lock detector. The coarse lock loop in the proposed DLL adjusts the delay between input and output clock within the pull-in range of the main loop phase detector. In addition, it monitors the main loop's lock status by dividing the input clock and counting its multiphase edges. Moreover, by using hysteresis, it controls the coarse lock range, thus reduces jitter. The proposed DLL neither suffers from harmonic lock and stuck problems nor needs an external reset or start-up signal. In a 0.13-${\mu}m$ CMOS process, post-layout simulation demonstrates that, even with a switching supply noise, the peak-to-peak jitter is less than 30 ps over the operating range of 500-1200 MHz. It occupies 0.04 $mm^2$ and dissipates 16.6 mW at 1.2 GHz.

  • Environmental problems increasingly serious, and sustainability in the fashion industry has become an essential factor. Nowadays, numerous brands are engaging in sustainable fashion activities, such as recycling, vegan, fair trade, etc., which have not been done before. However, there are limited studies about sustainable fashion activities focusing on luxury brands. The purpose of this study is to establish the current status of luxury brands' sustainable fashion activities based on the macro trend of Todeschini et al(2017)'s thesis. This study selected six global luxury fashion brands Louis Vuitton, Hermes, Gucci, Prada, Burberry, and Stella McCartney. Data were collected from the brand's websites and reports, fashion magazines, and Google. As a result of the study, the following adjustments are being implemented; first, efforts are being made to reduce the consumption of natural resources. Second, transparency on working conditions is provided in various ways. Third, luxury brands' awareness of the sharing economy was not opened. Fourth, efforts are being made to develop eco-friendly materials and technologies to minimize wastage. Based on these research results, if applied as basic data for the development of Korean fashion brands and start-up companies, it will help establish directions of sustainable fashion strategies.

  • Ethiopia is branded as the Water Tower of Africa because of its abundant inland water bodies that may be used sustainably to boost the economy. This review article's goal is to examine the current status and future potential of Ethiopia's fisheries, with a special focus on reservoirs. There are 200 known fish species (194 native, 40 endemic, and 11 exotic) in in Ethiopia's inland water. Ethiopia's fish production has increased by a factor of more than five in the past three decades (3,500 tons in 1983 to 15,681 tons in 2000 and 18,058 tons in 2010). However, fish produced in reservoirs is too low (8,059 t/year). The current fish harvests from reservoirs are significantly below the predicted potential yield, accounting for only 35% of the calculated fish production capacity. In this review, 14 potential reserves were revealed. A total of 48 fish species have been reported in these, of which 26 species (or around 54%) are present in Alwero reservoir. 19 of the 48 species that have been officially recognized belong to the Cyprinidae family and made up nearly 40% of the fish population in Ethiopian reservoirs. There has been, however, a decline in the productivity of Ethiopia's reservoir fish. Hence, actively start fishing in the numerous reservoirs that have been neglected yet, link the potential of fisheries and the benefits of the fish farming supply chain, let's begin building several other reservoirs similar to the Grand Ethiopian Renaissance Dam and beginning mechanized-based fish harvesting.

  • Nation-wide support is being strengthened to vitalize pre-entrepreneur and startup initiatives. However, it is found that they have been suffering from the lack of necessary information in preparation for the start-up operation. In order to support more proactive and robust start-up process in aspect of contents or service, it is necessary to carefully analyze their information needs and information seeking behaviors. Information seeking behavior analysis is a method for improving information services in accordance with the information needs of the information service users in libraries and information service institutes. This study analyzed information seeking behaviors of pre-entrepreneur and startup. Focus-group interview as the representative method of exploring information seeking behaviors was conducted. Content analysis was introduced to search the business-establishing process, information-seeking status, and utilization level of startup-related information resources and their perception. It is expected that contents and services for pre-entrepreneur and startup would be improved by reflecting their information seeking behaviors based on the results of this study.

  • This study suggests the ways to promote the technology startups founded by professor, who differs from student or researcher in social status, risk-taking tendency, and motivation. Literatures were reviewed to understand the advantage of faculty's tech start-up, foreign cases, and related researches. In addition, key stakeholders were interviewed. The study shows that domestic faculty entrepreneurship is currently in infant stage while facing obstacles in institutional, financial and practical aspects. In order to promote faculty entrepreneurship, the study suggests that university and professor set up the benefit sharing structure in advance, that the public sector establishes a holding company or investment fund dedicated to support a faculty startup, that proactive effort be made to attract passive professors to the startup world, and that private companies join faculty startups in the process of concept proofing and product commercialization. The study is expected to provide government, university, and industry with practical implication in promoting faculty startup.

  • In this paper, we propose a P4P based P2P system for live multimedia streaming services. In order to satisfy the strict requirement of delay in live multimedia streaming, in the proposed scheme, the P4P server of network provider provides the network status information related to delay and congestion links to P2P system in addition to the information to optimize the network resource utilization. The P2P system server, then, makes the peering suggestion based on the information from the network server. Also, we propose a playback synchronization mechanism that enable each peer to start the playback within the limited variation from the playback positions of source peer. Through the simulation results, it is shown that the proposed scheme not only deals with the original objective of the P4P framework, i.e., effective network utilization, but also the live multimedia streaming requirements. It enhances the playback continuity, and reduces the playback start-up latency and the control overhead. In addition, the proposed scheme reduces the variation in playback positions of the peers.

  • The Korean government is building a virtuous cycle of startups and venture businesses for a dynamic, innovative economy. This ecosystem is made possible when a social environment that embraces tolerance and turn business failure into re-startups and challenging venture startups by outstanding entrepreneurs are present. Due to the government's efforts to promote start-ups and venture businesses, their number has been increasing annually, but the efforts to create a social environment for re-startups and establish a relevant institution have recently started. This study is aimed at providing policy direction for re-startups by getting policy implications after identifying the current status of domestic failed businessmen' re-startups based on previous researches on failed businessmen. This study also reviewed advanced nations' cases and made international comparison of re-startup policies. Before the startup culture that recognizes failure as the stage for success is formed as in the U.S., it is necessary to create a legal basis for continuously pushing for the rechallenge policy of EU's Small Business Act and establish and operate the private sector-driven revitalization council of SMEs in Japan. It is also necessary to consider the guarantee of failed businessmen' livelihood. If additional research and government policies are added to the conclusions made on the policy implications, this research will provide an in-depth insight for revitalizing domestic re-startup.

  • Recently, the Korean government announced that it would focus on fostering intrapreneurship and corporate spin-off. The government encourages intrapreneurship because it ultimately seeks to develop industries and markets, grow innovative companies, and job creation. In particular, the government believes that enhancing intrapreneurship will reduce the personal fear of failures, expand open innovation by utilizing resources within existing companies related to innovation creation, and lead to new start-ups. Accordingly, this research reviewed the previous studies on corporate entrepreneurship activities and entrepreneurial self-efficacy and briefly looked at the status of global intrapreneurship activities. Based on the Global Entrepreneurship Monitor Adult Population Survey data in 2015, this study conducted a logistic regression analysis with the data of 27 OECD member countries' and Korean respondents. The finding confirms that the personal experience of intrapreneurship could be positively associated with entrepreneurial self-efficacy of the person. Therefore, it seems to be worth for the Korean government considering policies that support intrapreneurship as part of the start-up policy.
