지금의 게임 시장은 Stand Alone형식의 컴퓨터 게임을 디스켓이나CD와 같은 미디어를 판매함으로써 수익을 창출하는 것과는 달리 온라인 게임화 되어 사용자들이 얼마나 오랜 시간 동안 게임을 이용하였는가에 의해 수익을 창출한다. 다시 말해 온라인 게임 수익의 증가는 게임 이용자의 이용 시간 증가에 의해 결정된다[1]. 따라서 게임업계의 이윤은 바로 유저들의 게임을 이용한 시간 즉, 얼마나 게임에 대한 지속성을 최대화 한다면 이윤은 극대화 될 것이다. 그러면 이러한 게임의 지속성은 어떤 요소에 의하여 정해지는 것일까? 이 질문에 대한 답을 알 수 있다면 온라인 게임에서의 이윤추구는 더욱 쉬워질 수 있을 것이다. 본 논문에서는 온라인 게임의 총체적인 구성 중에서 게임을 구성하고 있는 색이 게임을 사용하는데 있어서 지속성을 가져다주는 중요한 요인이라는 주장을 입증하고자 한다. 이러한 주장을 입증하기 위한 근거로서 게임과 색의 기본적인 개념 파악 및 색이 우리에게 미치는 영향 등 이론 조사를 하였다. 다음으로 선행된 연구 자료를 인용하여 몰입과 사용시간, 색과 사용시간에 대하여 분석하고 마지막으로 사례분석을 통해 색채가 온라인 게임의 지속성에 영향이 있음을 알 수 있었다.

Rapid globalization process is applying to Science field in Korea. Until now, most researches and government's announcement used to examine the scientific level of Korea by using the number of publications in the SCI Journals. I investigate other aspects of the scientific globalization: a scientific collaboration trend, participations of foreign researchers, and the national level of collaboration networks. There are increasing patterns in collaboration and foreign researchers' participation, and the Impact Factors of the Journals were preceded by inflating trend in the participations of foreign researchers. Also, the breadth and the density are different from each science fields in the national level of collaboration networks. These findings are related to the process of globalization in the Korean science journals and the science fields.

This study primarily focused on the development of an Explainable Artificial Intelligence (XAI) model to discern and analyze papers with significant impact in the field of mathematics education. To achieve this, meta-information from 29 domestic and international mathematics education journals was utilized to construct a comprehensive academic research network in mathematics education. This academic network was built by integrating five sub-networks: 'paper and its citation network', 'paper and author network', 'paper and journal network', 'co-authorship network', and 'author and affiliation network'. The Random Forest machine learning model was employed to evaluate the impact of individual papers within the mathematics education research network. The SHAP, an XAI model, was used to analyze the reasons behind the AI's assessment of impactful papers. Key features identified for determining impactful papers in the field of mathematics education through the XAI included 'paper network PageRank', 'changes in citations per paper', 'total citations', 'changes in the author's h-index', and 'citations per paper of the journal'. It became evident that papers, authors, and journals play significant roles when evaluating individual papers. When analyzing and comparing domestic and international mathematics education research, variations in these discernment patterns were observed. Notably, the significance of 'co-authorship network PageRank' was emphasized in domestic mathematics education research. The XAI model proposed in this study serves as a tool for determining the impact of papers using AI, providing researchers with strategic direction when writing papers. For instance, expanding the paper network, presenting at academic conferences, and activating the author network through co-authorship were identified as major elements enhancing the impact of a paper. Based on these findings, researchers can have a clear understanding of how their work is perceived and evaluated in academia and identify the key factors influencing these evaluations. This study offers a novel approach to evaluating the impact of mathematics education papers using an explainable AI model, traditionally a process that consumed significant time and resources. This approach not only presents a new paradigm that can be applied to evaluations in various academic fields beyond mathematics education but also is expected to substantially enhance the efficiency and effectiveness of research activities.

This study examined the factors that influence the emotional expression in comments on the hot news about the 'Restaurant Collapse in Linfen City, Shanxi Province' published in Sina Weibo.. As a result of the study, first, there were differences in emotional expression according to gender. Women expressed stronger anger, disappointment, sadness, and condemnation than men. Second, the intensity of emotional expression of users in the eastern region was significantly higher than that of users in the central and western region. Third, the greater the number of Weibo, the total number of blogs where users participated in comments and posted emotional expressions, the stronger the emotional expression was. Fourth, unauthenticated users showed stronger emotional expressions of disappointment and sadness than authenticated users. The results of this study present implications for the factors influencing emotional expression on hot news. This study is meaningful in that it can be compared with social networks such as Twitter and Facebook in the West by looking at the factors that influence emotional expression in the process of online public opinion formation in China, and also meaningful in that a big data analysis method was used in online news analysis.

This study examines the factors that influence the chance of getting a full-time tenure track? position in universities in biochemistry. Its main findings are: first, as age at the time of getting a Ph.D. degree increases and the more recent a birth-cohort a female Ph.D. belonged to, the more likely she was likely to get a job; second, the number of citations of publications in science-citation indexed journals during a Ph.D. program period and the number of publications in science-citation indexed journals in post Ph.D. period increased her chance of getting a job; third, a post doctoral program and the duration of Ph.D. training did not affect a chance of getting a job; finally, a Ph.D. from a foreign university and a prestige ranking of a Ph.D. program did not influence a chance of getting a job.

The development of IT increases the importance of understanding of IT-driven ecosystems. Platform business is the representative business model in the era of innovative IT-based businesses. However, it lacks the review research that entails ecosystem perspectives from traditional disciplines in which the perspective of ecosystem had been applied. Further most of platform research have focused on the comparison between ecosystems as a whole rather than exploration on complementors in the ecosystem who are selected and survive and, in turn, contributed to maintain the ecosystem to compete with other ecosystems. The current study listed highly cited papers from economics, sociological ecology, socio-technical ecology, organization studies, and marketing research which have cumulated research on ecosystems. And the three most critical features that determine the success of complementors, which are competition, relationality, and adaptability. Present study showed how the features were explained by each perspective from the different disciplines.

This paper investigates determinants of litigation success in the two distinctive types of patent litigations, ex-parte and inter-parte cases, which are brought in the process where a filed application becomes a valid patent right. We regress winning rates of patent applicants on the characteristics of firms, trials, patent lawyer, and patent itself, using a probit model with sample selections. The paper finds that the relative suit rate of a firm, time to be sued, changes of patent agents by applicants, and multiple agents among explanatory variables affect ex-parte reexamination and in-parte post-grant patent trials differently in the point of average marginal effects. These variables lower the probability of applicant's victory in the ex-parte cases, while they raise the probability in the inter-parte trials. However, the experience that agents represent applicants is a winning rate-increasing factor both in inter-parte and ex-parte reexamination, unexpectedly. This result cannot be applied to the entire domain of the variable, since sample selection effects are reflected in the result. The number of claim increases the winning probability of the applicant in the both types of patent litigations. This study has some limitations because it ignores the information on the legal person to which a patent agent belongs, and confined agent's experience to patent filing. We leave it future studies to investigate the effects of lawsuit experience of patent agent, and those of characteristics of the law firm to which individual patent lawyer is affiliated.

In this paper, we review previous studies on the relative sea-level changes in the Yellow Sea during the Holocene to comprehensive understand the various research results. Currently, it is reported two theories : 1) the Holocene sea-level has never been higher than the present-day level; and 2) sea-level have reached highstand during mid-Holocene, followed by slow lowering to that of the present. The first theory yields a curve that is similar to a climate-change-related eustatic sea-level curve. However, in reality, most of the relative sea-level fluctuation resulted from land uplift or subsidence. The second theory yields a curve that is fairly coincident with a relative sea-level curve indicative of continental margins being located away from the ice sheets(i.e., far-field), and is considered as an effect of GIA(Glacio Isostatic Adjustment) and gravitational attraction. Based on detailed review of previous researches, we realized that they sourced the same papers, but obtained different results because they selectively chose and added the data. The data used to derive the second theory pertain to the northern Gunsan region, which is located within the western area of the Chugaryeong fault. Thus, we believe that the sea-level curve for the second theory is only representative of the area north of Gunsan, which is subject to GIA and tectonic deformation. Although the relative sea-level curve for the west coastal area is comparable to that for the far-field continental margin region, it is necessary to evaluate local tectonic activities as suggested by active seismicity in the west coastal area and the more than 400 faults currently existing in on the Korean Peninsula.
