This study analyzed the trends of home economics research in China by examining the distribution by period, keyword distribution, distribution of researchers, citation frequency, and distribution of research institutions. For this purpose, data collected from CNKI, spanning from 1984 to 2022, resulted in 149 articles selected for final analysis. The analysis conducted using CiteSpace for the bibliometric research method yielded the following results: Firstly, a significant amount of home economics research was conducted between 2018 and 2022, with a notable increase in research in 2015 and 2020. Secondly, the analysis of keyword distribution showed that research centered around home economics education, home economics philosophy, etc., was active, and various research areas formed clusters. Thirdly, the major contributors to China's home economics research were Li, Xiong, Xia, and Wu, who mainly conducted independent research. The research by Li (2006) had the highest citation frequency, and Jilin Agricultural University published the most research among the institutions. This study indicates that despite quantitative growth due to social changes, China's home economics research lacks diversity and consideration of research outcomes. Therefore, participation from scholars, practical application of the discipline, increased government support, and cooperation for future comprehensive and qualitative research are necessary.

This study analyzes the innovation performance of venture firms according to existence of venture capital investment, and according to type and ownership of venture capital. Venture firms are IPO firms that are registered on KOSDAQ between the year 2000 and 2016. They are categorized as corporate venture capital-backed firms (CVC) and independent venture capital-backed firms (IVC). Using patent data from KIPO (Korean Intellectual Property Office), we employ the number of patents and the citations per patent as the measurement of the innovation output. We find the positive association between the venture capital-backed firms and the number of patents before going public. Corporate venture capital-backed firms are positively associated with the number of patents before and after IPO. However, we do not find strong evidence between the number of citations and the existence of venture capital investment or the type of venture capital. Lastly, we provide an inverse U-shaped relationship between the innovation performance and venture capital's ownership. In other words, the innovation output, both the number of patents and the number of citations, gradually increases as the venture capitalist's ownership increases, but also shows a decrease pattern, suggesting that the venture capitalist's ownership does not only spur the innovation but also gives a negative effect on venture firm's innovation output such as excessive intervention. Overall, we reveal that the most important factor for the innovation performance is not the existence of venture capital investment or the type of venture capital, but the ownership of the venture capitalist.

A Metropolis genetic algorithm (MGA) is developed and applied for the structural design optimization. In MGA, favorable features of Metropolis criterion of simulated annealing (SA) are incorporated in the reproduction operations of simple genetic algorithm (SGA). This way, the MGA maintains the wide varieties of individuals and preserves the potential genetic information of early generations. Consequently, the proposed MGA alleviates the disadvantages of premature convergence to a local optimum in SGA and time consuming computation for the precise global optimum in SA. Performances and applicability of MGA are compared with those of conventional algorithms such as Holland's SGA, Krishnakumar's micro GA, and Kirkpatrick's SA. Typical numerical examples are used to evaluate the computational performances, the favorable features and applicability of MGA. The effects of population sizes and maximum generations are also evaluated for the performance reliability and robustness of MGA. From the theoretical evaluation and numerical experience, it is concluded that the proposed MGA Is a reliable and efficient tool for structural design optimization.

It is not easy to present a generalized operating model because the operating environment of a sport event is composed of a complex matrix structure. In this study, we propose 'standardization' which provides guidance of concept and process of sport event management to solve this sports event management problem. To purpose complete of this study, the frame was developed by the international standard ISO 9001: 2015 is applied. The standards framework for sports event process management system structure proposed in this study consists of scope of application, citing standard, Terms and definitions, organizational situation, leadership, planning, support, operation, performance evaluation, and improvement. This sport event process management system standard can be applied to any organization that wants to host, prepare, and operate sport events regardless of the form or scale of the sport event. In addition, this standard was focused on process management of life-cycle stages of sporting events, therefor it was possible to manage interrelationships and dependencies between processes and processes.

Despite the rapid development of IT technology, people with visual impairments still use simple forms of walking sticks and need more advanced walking aids. Smart Cane, which is developed based on Internet service and sensor, can provide high safety and convenience compared to existing sticks for visually impaired people by conveying peripheral information and walking situation to these visually impaired people through voice and vibration. In this paper, we propose and implement SmartKane to overcome lack of miniaturization, user friendly form, and sensing sensitivity, which have been pointed out as a problem of existing SmartKane.

To have global competitiveness in newly growing industry, good quality R&D's in convergence technology arerequired. Korean government also started to emphasize the importance of convergence technology as a new engine of growth for the future development. Since 2008, worldwide energy crisis and concerns on low carbon green growth made people focus on the convergence between information technology (IT) and energy technology (ET). However, the R&D performance comparison among the convergence technologies is not well explored so far. Therefore, this study uses Korea's patent citation database to measure the R&D performance of convergence technologies. We adopt technology development cycle, technology spillover analysis, and technology diffusion analysis to see the knowledge flow from R&D industry to others. We find that IT_ET convergence technology generally shows higher R&D performance than other convergence technologies. Contrary to public belief, convergence R&D by big companies has relatively low performance especially measures in technology spillover and technology diffusion. This implies that they might concentrate on delicate Fuel Cell Energy/Environment Technology (FEIT) or Nano Environment/Energy Information Technology (NEIT) rather than general energy information technologies. We also find that Korea's chemical industry may play a crucial role for the growth of other convergence technologies.

사람들은 누구나 시간과 장소를 구분하지 아니하고 의사결정을 내려야 할 상황에 처하게 된다. 특히 조종사의 경우에는 의사결정을 하여야 할 상황이 보다 시간적으로 제한되어 있고, 또 다른 어떤 경우보다 그 내용이 더 복잡하다는 특성을 가지고 있다. 특히 항공기 운항중 발생하는 조종사의 의사결정은 그 방법에 따라 결과는 아주 다른 양상으로 나타나게 되는데 합리적인 의사결정이 이루어졌다면 그 결과는 안전성과 경제성이 동시에 실현되지만 합리적으로 의사결정이 이루어지지 못하였다면 항공기 사고라는 최악의 사태로 이어지게 된다. 그러나 현실적으로는 조종사들이 사회, 문화적 특성과 개인적인 태도 및 성격에 따라 집단내 구성원들의 의사를 종합하여 의사결정을 얻지 못하고 경우에 따라서는 기장 개인의 능력에 따라 의사결정이 이루어지고 있는 실정이다. 이러한 점에 착안하여 본 연구에서는 조종사의 합리적인 의사결정에 영향을 미치는 요인들을 분야별로 내용을 분석하고 의사결정의 이론적 고찰을 통해 조종사의 합리적인 의사결정을 위한 방안을 제시하고자 하였다. 특히 조종사 자격 관리 및 능력개발 프로그램시 태도 변화를 위한 교육이 우선해야 한다는 것과 그리고 미국의 여러 기관에서 연구 수행한 결과를 인용하여 조종사의 태도분석방법을 소개함으로써 조종사 자신들이 직접 지니고 있는 위험한 태도 요소를 자각할 수 있도록 하였으며 이에 대한 행동상 지켜야 할 원칙을 제시하여 자신이 의사결정을 해야하는 경우 적용할 수 있도록 하였다. 앞으로 이와 관련하는 지속적인 연구를 함으로서 합리적인 의사결정을 위한 요인들의 상관관계를 분석하고 항공기 운항분야중에서 부분적이나마 정형적인 의사결정모델이 개발될 때 항공기 안전운항에 크게 기여할 것으로 기대된다.
