The province of the People's Republic of China, the Xinjiang Uygur Autonomous Region has historically been known under various names - Eastern Turkestan, Chinese Turkestan, Kashgaria, etc. In the early 19^th century this region was one of the least explored in Western scholarship and for the influence over which the so-called 'Great Game', geopolitical rivalry between Great Britain and the Russian Empire, gradually unfolded. This rivalry was one of the significant factors stimulating increased interest in an in-depth and comprehensive study of the geography, nature, and population of Kashgaria. Accordingly, in the second half of the 19^th to early 20^th centuries, several expeditions were organized that pursued serious academic goals alongside military, diplomatic, and commercial purposes. One of these expeditions, organized by the Imperial Russian Geographical Society, was the so-called 'Tibetan expedition' led by a talented scientist and military figure M.V. Pevtsov in 1889-90. The expedition followed the routes of Eastern Turkestan, the northern outskirts of the Tibetan Plateau, and Dzungaria studying this vast region's geography, topography, nature, climate, and population. The results of this investigation were presented by M.V. Pevtsov in a detailed and comprehensive report published in St. Petersburg in 1895. An important part of this narrative is the so-called "Ethnographic Essay of Kashgaria," which reflects the author's observations and thoughts on this region's ethnic composition, religious beliefs, language, customs, and rituals. This article offers insights and analysis of the content of Pevtsov's report, which provides valuable information about the daily life of the population of Kashgaria at the end of the 19^th century to an English-speaking audience.

The mobile application (APP) market is growing at an unprecedented speed. Amid such growth, the global platform providers are mandating exclusive in-app payments and charging 30% for platform commission fees. A serious tension has arisen between mobile global platform providers and local content providers. The present study attempts to analyze the domestic mobile game market and in-app payment commission fees. This study estimates the size of the domestic mobile game market and platform commission fees by directly using publicly available financial statements and footnote information of some representative listed mobile game firms. Also, the study analyzes the cost structures of the same sample firms and attempts to draw some implications on sustainable growths of the mobile game ecosystem. We estimated that, in 2019, the domestic mobile game market is around 4.9 trillion Won and the ensuing in-app payment commission fees market was 1.5 trillion Won. High market share firms display a proportional increase in in-app payment commission fees in relation to sales growth. This, in turn, makes the in-app payment commission fees a primary cost item far exceeding employee salaries and R&D expenses. During the same period, low market share firms generated a mere profit or experienced net loss. Analysis of the cost structure reveals that these firms are even more liable to higher in-app payment commission fee cost structure than high market share. Most constituents of the mobile game ecosystem are small business entrepreneurs. By employing a micro-level analysis, the study estimates that, in 2019, a representative median firm generates 530 million Won in sales. At the same time, it spends 190 million Won in employee salaries, 50 Won million in R&D and 190 million Won in in-app payment commission fees, respectively. In the absence of other cost items, these three cost items alone account for 73.8% of sales revenue. The results imply that a sustainable growth of the local mobile game market heavily depends upon the cost structure of such representative median firm, the in-app payment commission fees being the primary cost item of such firm.

This study examined the effects of smartphone usage types and excessive expectation for smartphone on adolescents' smartphone overdependence. It utilized the data of 3,454 adolescents (1,758 males and 1,696 females), aged between 13 and 19 from a smartphone overdependence survey of the National Information Society Agency. As a result of the hierarchical multiple regression analysis, age and household income had a negative effect on smartphone overdependence. Weekly smartphone usage time positively affected the serious consequences (sub-factor of smartphone overdependence). Among the different types of smartphone usage, information seeking, SNS, gaming, and the excessive expectation for smartphones had positive impact on smartphone overdependence. Smartphone usage for leisure seeking did not affect smartphone overdependence, but it negatively influenced serious consequences. Messenger use did not affect smartphone overdependence, but the use had a positive effect on salience, and a negative effect on serious consequences. The results of this study suggest that it is necessary to identify the types of smartphone use as well as the usage time to understand the smartphone dependence of adolescents. In addition, it seems necessary to recognize and correct the irrational excessive expectation for smartphone in order to prevent dependence and implement effective interventions.

In this paper, through conducting a survey from 547 male and female high school students in Busan, we found their favorite computer games are about five and the highest linguistic problem in on-line computer games was vulgar languages. Most of respondents thought that the vulgar languages on the on-line games were serious and said that we have experienced the vulgar languages before high school. Therefore, in this paper, we suggest it is necessary to prepare a countermeasure system about adolescents' vulgar languages on the on-line games and for adolescents to take etiquette lessons on the on-line games from either the primary school or before then.

Purpose: The present study purposed to investigate the current state of harmful business places around schools and to survey and analyze how much middle school students know about school environment hygiene purification zones, which have not been much effective. Methods: In addition, this study clarified the problem of harmful environment around schools by inquiring into students' value and perception on worsening harmful environment around schools and provided basic materials necessary for making policies on school education and the protection of educational environment. For these purposes, we conducted a questionnaire survey of 1,000 middle school students in Gyeonggi-do on their perception on harmful environment around their schools, and drew conclusions as follows. Result: Students' knowledge about the School Health Act was low, and they generally thought that the law does not play its role substantially and efficiently in purifying and regulating harmful environment and regulations are superficial and temporary. To the question of whether harmful businesses observe laws for purifying environment around schools, most of the students replied negatively. In actuality, as most of harmful businesses running at school environment hygiene purification zones are stationeries with game rooms, comic book stores, PC rooms, etc., which are highly accessible to students, they become serious problems in school environment. Conclusion: As it is required to make continuous and systematic surveys and researches on the school environment hygiene purification zones, we need to manage school environment efficiently through cooperation among the government, education offices and individual schools.

The content industries environment has been undergoing significant changes due to rapid technological innovation and content market expansion. Interest in the industry is growing fast both in Asia and Europe. However, in Japan content industries are showing almost zero growth with no increase in overseas expansion. Until now, Japanese content industries have been able to grow based on domestic demands. Many different factors contributed to today's zero growth in Japanese content industries. Two main reasons are: 1) Their lack of interest in overseas expansion and 2) Insufficient investment in domestic human resources development. Considerable amounts of Japanese contents including films, music, games, and animations have been distributed in many Asian countries and today piracy problems in the region are at a serious level. According to 2004 records pirated editions accounted for 85%, 16%, 19%, and 36% in China, Korea, Hong Kong, and Taiwan respectively. Pirated editions bring economic losses to Japanese copyright profits. Making it worse, they weaken the motivation to create content and make it hard to activate cultural exchanges. Losses from copyright violations in Japanese content industries are expected to keep increasing in the future. In order to make Japan competitive and grow it is crucial to take proper measures to protect copyright infringements. This study considers the current situation of the Japanese content market, infringement issues in content which is causing many problems in Asian countries, including China, and facts about losses caused by this problem.

Today the lectures are usually practiced in a teacher-led traditional classroom system or a student-led e-learning system. Students passively follow the teacher's lectures in both systems, though. Also due to the advances in 3D Computer Graphics and Game technologies, there are trials to exploit the positive effect of games in learning. The serious games, specifically designed games for an educational goal, or existing games for a special class have been used as lectures. Still these games have a great difficulty in being integrated into the educational system technically and economically. Therefore a new 3D MMORPG based lecturing system is presented in this paper. In our new lecturing system, the characteristics of a 3D MMORPG, achievement, sociality, and immersion, are provided to motivate students to participate actively in a lecture. A teacher and students interact with each other in realtime as 3D characters in a 3D virtual classroom on-line. An ordinary teacher can also easily apply our new system to existing classes since a teacher only needs to specify a slide file to prepare a lecture. For the future work, a user study and the effect of our new lecturing system will be performed.

The topic of this study is a survey research about the economic recognition related to economic ethics and information literacy of students(6,779) extend from elementary school to university. First, for the ability to use computers, it is recognizing that 49.6% of students are normal, 38.6% are superior, and 12.8% are inferior. In part of class, it tends to recognize that it is the superior as the level of school is the lower excepting middle school students. Second, we can find great difference between male students and female students related to purpose of using internet, 79.8% of male students are using computer to play game or entertainment(1), search data or knowledge(2), chatting or massenger(3), 70.1% of female students are using internet to search data or knowledge(1), chatting or massenger(2) and meeting of similar taste. Third, it shows a tendency that the economic activity using internet or cell-phone increases faster as the level of schools is higher. In detail, they primarily use buying or settlement of products(63%), purchasing internet service(20.9%). Fourth, for using illegal CD, not only they didn't feel guilty in all levels of schools, excepting university students, it is showed that the trust of intellectual poverty right is weaker as the level of schools is higher. So, it is becoming serious problems. It seems a task which should be supplemented through economic education of schools in the future.

In this study, 1 have analyzed the state of the use of information technology by the at-risk children who are residing in Husan metropolitan area. The ultimate goal of this study is to help ensure the healthy development of the children and improve the quality of their lives in this information-oriented society. For this research, 1 surveyed 183 children living in an institution or a low-income family in Busan metropolitan area. The survey questionnaire was designed to obtain information on the respondents, socio-demographic characteristics, computer-related conditions of the immediate and social environments, patterns of computer and Internet use, their experience and degree of so called, Net-generation syndrome, Internet addiction disorder, changes in social and familial life caused by Internet use, and exposure to pornographic materials. The results show that 95.9 % of at-risk children in Husan own a computer, 60.9 % of those computers being Pentium Ⅲ. A majority of the children (74.9 %) are connected to Internet at a high-speed, using such devices as LAN, ADSL or cables. About seventy-six percent of the children have used a PC and Internet less than two years. In other words, a majority of them have not used those for a long period of time. The main results of the research are summarized in the following: There is a significant difference among at-risk children in terms of experiences in computer and Internet use according to their grade levels. There is a gender difference in the amount of time spent on computer and Internet. Boys spend more time every week on computer and Internet than girls do. There is a significant difference in the pattern of computer and Internet use, according to the type of their risk, and grade level. The so-called 'Net Generation Syndrome' is not serious in this group. A majority of the at-risk children think that Internet is more interesting than TV. They hardly shop on Internet, and they don think the advertisements on Internet are a serious problem. Also, unlike many people assumptions, their desire to communicate through on-line chatting was very low. They do not tend to buy computer game programs, and Internet Addiction Disorder was not pronounced among them. The at-risk children rarely had an exposure to pornographic materials in the cyber space. However, the exposure was more frequent for institutionalized children than children in low-income families. These results point to a need for a policy to improve the welfare of at-risk children and guarantee their right to information.

When new services are introduced, one of the drivers for market performance of them is the interactions among existing and new services. They are characterized by the substitution or complementary effects among existing and new service or the cannibalization of existing services by new services. This paper analyzes these issues in the telecommunications service industry context. To analyze them, a simple graphical tool or State Transition Diagram(STD) is developed and used. The diagram helps to clearly represent and explain the substitution, complement and cannibalization impact. Then, using the face-to-face survey of 1,200 people, a new wireless internet access service or WiBro is analyzed to identify the substitution/complement and cannibalization impacts in relation with the other competing services. Additionally, the important factors explaining customer subscription and substitution behavior are identified. The analysis results indicate that males, students or on-line game users are more likely to subscribe WiBro. Also, among the potential WiBro subscribers, customers who are less satisfied with the existing fixed line broadband internet access services are more likely to stop subscribing the fixed line service, which implies substitution by a new service. Additionally, this raises the issue of cannibalization if the existing and new services are provided by the same company. In fact we find the cannibalization effect is more serious for the cost sensitive group. We believe that our tool, approach, analysis results and their implications would be very helpful to devise a winning strategy for the new services in the highly uncertain telecommunications business environment.
