Expert systems represent the application of artificial intelligence research that is at least 10-15 years old. It may well take another 5-10 years before the present technology is exploited by industry. The objective of this paper is to show the applicability of Combined Hypertext-Expert System Techniques to the professionals working in the construction industry. Expert systems alone don't give the user any control over the system. Hypertext systems that focus only on displaying messages have the opposite problem. While they allow the user to control the system., the only control the system designer has is in setting up the hypertext links. Therefore the combination of these two techniques, offered by KnowledgePro, may bring us closer to real user-expert communication. The system developed in this work offers information on ACI Manual concerning various problem areas in concrete practice, consultation about mix design of concrete and guidance to identify types of cracks in concrete. Once the type of crack is identified through the rule-based knowledge, the system provides the user with remedial measures through the control of the user.

Information about camera operating such as zoom, focus, pan, tilt and tracking is useful not only for efficient video coding, but also for content-based video representation. A camera operating parameter measurement system designed specifically for these applications is therefore developed. This system, implemented in real time and synchronized with the video signal, measures the precise camera operating parameters. We calibrated the camera lens using a camera model that accounts for redial lens distortion. The system is then applied to infer image motion from pan and tilt operating parameters. The experimental results show that the inferred motion coincides with the actual motion very well, with an error of less than 0.5 pixel even for large motion up to 80 pixels.

Government R&D grants for SMEs have risen to three trillion Korean won a year, placing Korea second among OECD nations. Indeed, analysis results have revealed that government support has not only expanded corporate R&D investment and the registration of intellectual property rights but has also increased investment in tangible and human assets and marketing. However, value added, sales and operating profit have lacked improvement owing to an ineffective recipient selection system that relies solely on qualitative assessments by technology experts. Nevertheless, if a predictive model is properly applied to the system, the causal effect on value added could increase by more than two fold. Accordingly, it is important to focus on economic performance rather than technical achievements to develop such a model.

The Korean government has focused on universities or colleges as the main targets of its startup policy since the 2010s. However, the performance is not so good, with a low survival rate. The purpose of this study is to examine the factors that underpin the success of student startups. First, through a review of the literature, this study compared the success factors of student startups with those of venture startups, which means the general startup sector, as well as youth startups, also a focus of startup policy targeting youngsters outside universities or colleges. Second, we analyzed case studies of startup companies connected University H. The literature review showed that the main target of student startups is the employment of university students. There is a lack of studies on success factors; existing studies only emphasize the entrepreneurship of students. The results of case studies showed several factors of success similar to those of general venture startups: founders, business model and resources including team, and mentoring.

The COVID-19 curve seesawed and reached the fourth pandemic in July 2021. Since the first three waves, the focus has been on achieving herd immunity through vaccination while a lot of manpower is used for quarantine. However, we have not been able to prevent the fourth wave. The causes are thought to be related to people who doubt the safety of the vaccine and refuse it or violate quarantine guidelines such as social distancing. This study examined guidelines for preventing and controlling COVID-19, the accuracy of vaccination-related information, and described quarantine measures including for those who completed vaccination. In conclusion, prevention and vaccination are the most effective countermeasures against COVID-19. We recommend people vaccination with self-quarantine. Also, it is necessary to make large investments to protect and support nurses in future pandemics.

Purpose - This paper examines the effects of host country's non-economic factors on foreign affiliate's financial and operational performance. Design/Methodology - Using Korean-owned foreign affiliate-level data, we employ various measures that represent host country's non-economic factors and examine their effects on foreign affiliate's performance. We further investigate the effects of local top managers and local middle managers on the impact of country's non-economic factors on foreign affiliate's performance. Findings - We find that local top managers are effective in increasing foreign affiliate's financial performance by dealing with institutional and cultural factors, particularly in high-income countries, while local middle managers are effective in increasing affiliate's operational performance by responding to the changes in doing business factors, particularly in low-income countries. Originality/value - Considering that most of previous FDI studies focus on examining host country's economic factors on firm's FDI decision, our findings suggest that country's non-economic factors are strongly associated with actual business performance of foreign affiliates.

This study was undertaken to confirm the relationship between the manner of focus and job performance of clinical dental hygienists. A survey was conducted, and the results of the survey were analyzed using multiple regression analysis. As a result, in the correlation between job performance ability and focusing manner and appreciation of the experience process, which are sub-factors of job performance ability and focusing manner, r=.161 (p<0.1) and appropriate distance r=.229 (p<0.1) indicated a positive (+) correlation. Multiple regression analysis revealed that the factors that have the greatest influence on job performance are type of workplace (β=-0.381), focusing attitude (β=0.166), marital status (β=-0.156), and age (β=0.152). Therefore, by confirming the relationship between focusing and job performance ability, we intend to provide the basic data necessary to prepare measures to improve dental hospital management and job performance.

Noting the changes within the Singapore construction industry, fuelled by the government's 'green' initiatives in tandem with the prolonged effect of the 1997-2005 recession, this paper investigates Singapore contractors' attitudes towards environmental sustainability. Data were collected from 34 interviews with senior management of large and medium-sized general building contractors and the firms' archival records. The results show that the majority of the contractors embrace positive attitudes towards environmental sustainability. The respective contractors explicitly express their environmental drives by incorporating keywords such as 'quality', 'sustainability' and 'environmental and social benefits' into their firms' mission statements. The results also show that three environmental-related measures implemented by all contractors are: (i) stricter housekeeping procedures in construction sites; (ii) stricter wastage rates for construction materials; and (iii) greater focus on Just-In-Time delivery to minimise materials deterioration due to inappropriate site storage.

Anti-circumvention rules were discussed profoundly during the Uruguay Round and the DDA negotiations, although WTO members failed to reached an agreement to introduce it to the WTO Anti-Dumping Agreement. However, as the cases of circumvention of anti-dumping duties increase, a number of countries have enacted anti-circumvention regulations as part of their anti-dumping laws. This study aims to analyze anti-circumvention rules from the perspective of WTO law. After overviewing the object and purpose of anti-dumping and anti-circumvention regulations, it examines anti-circumvention regulations of the US, the EU, and India. Next, the study explores the possible WTO-inconsistent aspects of those regulations. Then, it discusses whether it would be preferable for countries not equipped with anti-circumvention regulations, such as Korea, to have one. Thereafter, this study proposes Korean government to introduce anti-circumvention rules into its anti-dumping law.
