The Korean online gaming industry has seen rapid growth since the boom of information technology (IT) related industries, especially Internet and PC-bang or local area network (LAN) use, throughout the country. Online games are real-time games in which two or more players meet, compete, and cooperate in the same game space using the same communication network. Even though the growth rates of IT-related industries have recently slowed, the growth of the online gaming industry has increased, and Korean firms are expanding their businesses to countries all over the world. However, the online gaming industry is becoming an oligopoly, in which 4-5 leading companies occupy most online gaming markets. This situation presents a disadvantage to the Korean online gaming industry, since online players usually seek a diversity of online gaming contents and high quality online game services. Therefore, small- and medium-sized game developers must survive in this market by upgrading the quality of their online gaming services in an effort to provide differentiated goods and services in monopolistic competition markets. However, most venture companies in the online game industry, whether new or previously existing, are not able to obtain adequate financing. The objective of this paper is to examine the management environment for medium- and small-sized game developers in the Korean online gaming industry. By introducing the case of Grigon Entertainment, we try to identify the source of difficulty obtaining external financing for Korean venture firms in the online gaming industry.

2020년 COVID-19 확산으로 인해 대학은 개강 연기, 전면적 비대면 온라인 수업 체제를 도입 및 운영하게 되었다. 이에 본 연구의 목적은 온라인 수업 시행에 따른 학습경험 분석을 통해 온라인 수업의 교수·학습의 질 제고 방안 탐색을 위한 기초자료를 제공하는데 있다. 본 연구는 한국교육개발원 2020년 대학 교수·학습과정에 관한 설문조사(NASEL) 결과 중 C대학의 자료를 활용하여, 온라인 수업 유형(실시간 수업, 녹화 수업)에 따른 학생의 학습경험과 교수·학습 성과와의 관계를 파악하고, 이 과정에서 온라인 수업에 대한 인식 및 태도의 매개효과가 발생하는지 등을 분석하고 자 구조방정식 모형을 사용하였다. 연구결과는 첫째, 학습경험이 교수·학습 성과에 정적인 영향을 미치는 것으로 나타났다. 둘째, 온라인 수업 유형에 따라 학습경험이 교수·학습 성과에 미치는 영향력이 다르게 나타났다. 녹화 수업보다 실시간 수업에서 학습경험이 교수·학습 성과에 미치는 영향력이 더 크게 나타났으며, 온라인 수업의 인식 및 태도가 교수·학습 성과에 미치는 영향력은 녹화 수업에서 더 큰 것으로 나타났다. 학습경험과 교수·학습 성과의 관계에서 온라인 수업에 대한 인식 및 태도의 매개효과는 나타나지 않았다.

The parameters of transmission lines have an influence on the electromagnetic environment surrounding the line. This paper proposes a method based on phasor measurement unit (PMU) and supervisory control and data acquisition (SCADA) to achieve online estimation of transmission line full parameters, such as resistance, reactance and susceptance. The proposed full parameter estimation method is compared with the traditional method of estimating resistance independently based on SCADA system. Then, the electromagnetic environment is analyzed based on the different parameter estimation methods. The example results illustrate that online estimation of transmission line full parameters is more accurate in the analysis of electromagnetic environment, which further confirms its necessity and significance in engineering application.

Recent market environment shows a new relationship between customer and company. You can easily observe customers take initiatives to get involved in the marketing activities such as product development, pricing and distribution etc. Despite the fact there are a lot of marketing activities initiated by customers in the online travel market, customer participation has been given little attention in the academic literature. Our research is grounded in the well-known commitment-trust theory of relationship marketing, originally proposed by Morgan and Hunt(1994). According to the theory, trust is central to successful relationship marketing. This study explores the effect of trust on customer participation in the online travel market. Consequently, this study suggests some managerial implications for marketing strategies in response to customer initiative in the marketing activities on the online travel market.

정보검색의 성공여부는 적절한 검색어의 선정에 달려있다고 해도 과언이 아니다. 특히 CD-ROM이나 온라인목록시스템에서 주제검색시 분류표, 주제명과 같은 통제어와 자연어 등 비통제어의 비교 우위 문제는 아직도 논란이 되고 있다. 본고는 두 시스템의 검색효율성을 비교하기 위하여 특히 다언어 환경하에서의 검색어 사용에 중점을 두고 다양한 형태의 검색어휘를 조사 분석하였다.

최근 스마트 폰 기술의 급속한 발전에 힘입어 모바일 컴퓨팅 환경에서의 온라인 게임의 설계에 대한 관심이 높아지고 있다. 그러나 모바일 단말인 스마트 폰은 비교적 낮은 성능의 프로세서, 저해상도의 GUI, 작은 메모리 공간과 짧은 배터리 파워 등의 제한으로 온라인 게임 구현에 많은 제약이 따른다. 따라서 대부분의 게임은 온라인이나 멀티 플레이 기능이 매우 제한적이다. 본 논문에서는 이러한 모바일 환경의 제약을 극복할 수 있는 컴포넌트 기반 스마트 폰 환경에서의 효율적인 모바일 온라인 게임 앱을 설계하고 구현하였다. 특히 본 논문에서 구현한 모바일 게임은 Wi-Fi를 기반으로 게임 서버와 다른 스마트 폰 간의 온라인 게임이 가능하도록 구현하였다.

It is crucial to understand the characteristics of learner questioning due to the effects it has on learning. This study focuses on the effects of middle school students questioning on their academic achievement in an online inquiry learning environment. A survey of 827 middle school students was conducted; the students took part in an online math and science program offered by a center for the gifted. Throughout the survey, learner questioning was analyzed, and its correlation with academic achievement was investigated. An analysis was based on questioning categories of a low- and high-level questions from previous studies. Through the survey, it was found that the number of learner questions asked in the online environment was small, but the number of low- and high-level questions were almost equal. Secondly, the higher the academic achievement level of the student, the higher the possibility they would ask either low- or high-level questions. Lastly the group of students in both low- and high-levels of questioning earned the highest average scores on formative evaluations and inquiry tasks. This indicates that regardless of the level of questions, the act of questioning itself is highly related to the academic achievement. However, in the case of advanced learning projects, the quality of questioning and high-level questioning affected the academic achievement of students. Based on these results, implications for the encouragement of learner questioning and support for asking high-level question are suggested.

The novel coronavirus pandemic has had a significant impact on society and everyday life. The pandemic imposed a global shutdown leading to many challenges such as the suspension of academic programs at universities. The result of this suspension contributed to the rapid overnight migration of educational activities from traditional face-to-face learning to a virtual environment which until then was unfamiliar to both instructors and students. This study identified the experiences faced by built environment higher education instructors in KwaZulu-Natal, South Africa during this sudden switch to online teaching and learning. This pilot study employed a quantitative research approach to survey instructor experiences on online teaching and learning during a global pandemic. The data was computed and analyzed using IBM Statistical Package for Social Sciences (SPSS) version 27. Descriptive statistics were used to analyze the data collected. The study sample comprised of 20 higher education instructors in the region of the KwaZulu Natal province in South Africa. Findings from the study revealed that instructors faced adaptive challenges with rapidly having to redesign and remodel the mode of academic course delivery and assessments to suit an online platform. Additionally, instructors observed that students faced technological challenges such as connectivity and navigating the online learning management system platforms. The challenges identified by instructors and students can be effectively transformed to opportunities for future learning under the 'new normal'.
