International trade has been changed from traditional trade to e-trade due to the fast expanding of information technology like e-marketplace, EDI (Electronic data interchange) using Internet since mid of 1990's. e-Trade, as a new trade method, could handle every trade procedure such as market research, contract, customs clearance, logistics and payment using IT like internet without restriction of time and space. The evolution of transaction-based business model is upon us. The business models of many e-Marketplace in their early stages have typically been based on transaction fees. Many e-Marketplaces have even called out transaction revenues as a core element of their business plans. The transaction business represents the most simple of business models, but it does not provide a long-term sustain able advantage. For buyer's convenience, wide selection and test price hold appeal. For suppliers, the extended global market reach and direct access to customers and consortiums of customers is powerful. To maximize leverage of these new e-marketplace, you must from both a buyer perspective as well as a supplier perspective. Also required is a strategy that takes in account all of the various e-Marketplace transaction standards and one that allows the easy accomodation to new e-marketplace as the market change. These new e-marketplace will need to be factored into the sales channel strategies. To be successful, integration with these e-marketplaces should occur at a complete business process level. This study would suggest on the role of buyers and sellers for e-trade which could maximize effect of e-trade in order to cope with rapid changing IT environment and global trade environment. Therefore, this study suggests top priority tasks for implementing on the specialization strategy of e-trade process.

Mobile IP (MIP) and SIP are considered as important technologies to provide the macro mobility in the next generation mobile convergence networks which have heterogeneous access networks. Typically, MIP and SIP are more suitable for the non-real-time TCP connections and the real-time RTP/UDP sessions respectively, hence a handset which uses both of these sessions should simultaneously apply MIP and SIP to perform the efficient mobility management. Existing multi-layered mobility management schemes focus on the signalling order of each protocol. However, simple combining of two protocols cannot provide the performance enhancement of the mobility management. In this paper, a novel multi-layered mobility management algorithm using the combination of SIP and fast MIPv6 (FMIPv6) is proposed. FMIPv6 and SIP mobility is simultaneously performed to reduce the service interrupt time and to guarantee QoS requirement. The delay model is defined to analysis the performance of the algorithm and the simulation results show the performance of the proposed algorithm.

Name authority control is important for not only library catalogers but also end users, since it provides uniform access points. The national libraries in Japan and the United States have constructed and controlled authority records for writers from early days, and have provided them on the web sites. The purposes of this study are to extract common fields and differences in Japanese writer's name authority records of the U.S. and Japan, and to propose the ways of desirable description of authority records in Korea. Several suggestions of building authority records in National Library of Korea such as open to the pubic of authority records, provision of various forms of authority files, suggestion of the ways of writing the names of foreign writers, and the links between the authority records and library catalogs for retrieval are proposed.

Background : This study aims to examine actual conditions of college students' life, behaviors to prepare for employment, and employment performance, thereby providing basic materials to create efficient measures for college students' employment strategies. Method : The subjects of this study were 207 graduates from the Department of Physical Therapy employed in medical and health institutions in Gyeongsangnam-do and Busan. Aquestionnaire devised by Yu Yeon-wha and Lim Gyeong-ae(2012, 2011) was revised and complemented into a self-reporting questionnaire composed of 29 questions. The collected data was analyzed using SPSS Win 18.00 program. Results : 1) The biggest reason for the respondents' selecting physical therapy as a major was bright prospect for employment, and the largest percent of the respondents answered that they started to prepare for employment in the second semester of junior year. 2)Regarding behaviors to prepare for employment, those who largely provided information on employment were the respondents' seniors and friends. 62.3% of the respondents owned certificates and diplomas. 59.9% took part in programs related to employment in order to prepare for employment. Their weakest area was English and what they wanted to know most was annual salaries provided by companies. They put self-development and growth potential before everything as what should be considered in priority when getting a job. 3)The most frequently asked question in their interviews for employment was the motive for application. The biggest reason for their employment at their current institution was their good personality and manner. 4)As for employment performance, they were unsatisfied with their current average annual salary. Conclusion : School should provide consciousness education and employment coaching so that students can early prepare for employment with an active attitude. In particular, educational environment where many students can gain easy access to information about employment in diverse areas should be provided and student coaching should be actively conducted.

Background: Children today get access to smartphones at an early age. However, their ability to use mobile apps has not yet been studied in detail. Purpose: This study aimed to assess the ability of children aged 2-8 years to perform touchscreen gestures and follow prompting techniques, i.e., ways apps provide instructions on how to use them. Methods: We developed one mobile app to test the ability of children to perform various touchscreen gestures and another mobile app to test their ability to follow various prompting techniques. We used these apps in this study of 90 children in a kindergarten and a primary school in New Delhi in July 2019. We noted the touchscreen gestures that the children could perform and the most sophisticated prompting technique that they could follow. Results: Two- and 3-year-old children could not follow any prompting technique and only a minority (27%) could tap the touchscreen at an intended place. Four- to 6-year-old children could perform simple gestures like a tap and slide (57%) and follow instructions provided through animation (63%). Seven- and 8-year-old children could perform more sophisticated gestures like dragging and dropping (30%) and follow instructions provided in audio and video formats (34%). We observed a significant difference between the number of touchscreen gestures that the children could perform and the number of prompting techniques that they could follow (F=544.0407, P<0.05). No significant difference was observed in the performance of female versus male children (P>0.05). Conclusion: Children gradually learn to use mobile apps beginning at 2 years of age. They become comfortable performing single-finger gestures and following nontextual prompting techniques by 8 years of age. We recommend that these results be considered in the development of mobile apps for children.

Objective: The aim of this study is to give interest about usability of cellular phone keypad for left-handed person. Background: Although there are being a lot of attempts to design suitable product on user's request in process that design cellular phone keypad, ergonomic access about left-handed person who compose decimal class is unprepared. Especially, in early user's occasion, left-handed persons need more efforts than right-handed person to master Hangul character input process skill level. But, since realization about this left-handed person's discomfort has not spread, the importance has not been well thought in the society. Method: (1) After extracting emblem to use in comparison in questionnaire, applied emblem uniformly to different 3 kind of cellular phone. (2) Measured Hangul input time and mistyping number by dominant hand's position and skill level to reagent. (3) Taking the result through ANOVA. Conclusion: In the result of the experiment about Hangul input time and mistyping number according to dominant hand's position and skill level, left-handed person's group on the low skill level has shown the dullest use capability among 4 experiment groups. Application: In the future, analysis result may be used to the data of realization conversion in process design of various products including cellular phone keypad to consider left-handed person.

To find health problems of Pohang city and to plan the activities to solve them in the situation of localization, the mortalities of the citizens in recent three years from 1994 to 1996 were analyzed from the notices and the certificates of death. The ratios of the notices with the certificates of death In the rural area of Pohang city were higher than those of whole country, the ratios of the urban area were lower than the respective ones, and the ratio differences between the rural and urban area were increasing. It may be that medical facilities are not within easy access of the rural inhabitants. especially in the rural south district with high population density. The proportional mortality indicators(PMI) were lower them those of whole country, much lower in male. So the health status of young aged males is relatively unsatisfactory. The urban inhabitants died in hospitals about two times more than the rural inhabitants and the differences were increasing. It may be that living and housing conditions and socio-cultural differences affected on the places of death. Because it is thought that death in hospitals will be growing at high speed, it is necessary to enlarge facilities fur funeral services. The age standardized mortalities were lower than those of whole country and age grouped mortalities were also the same. There were not any consistent and meaningful findings in the sex ratios of mortality according to the age groups or the calendar years. The mortalities by neoplasms and cardiovascular diseases according to the twenty one major causes of death were rapidly increased from the middle ages in both male and female. So it is important to plan the activities for early detection and health maintenance or promotion by behavior modifications. The leading causes of death were cardiovascular diseases, hypertensive diseases, and traffic accidents. And accidental drowning because of coastal area, liver diseases in male, and low respiratory tract diseases in female were the leading causes of death in part of age groups.

Like other wireless network protocols, IEEE 802.15.4 adopts CA (Collision Avoidance)algorithm to avoid the early collision of a new packet by randomizing its first transmission time rather than its immediate delivery. The traditional CA scheme of IEEE 802.15.4, however, selects the random access time from the predetermined range without considering the degree of current congestion. It probably causes either a long delay to settle in the suitable range for the current network load or frequent clashes especially during the long lasting heavy traffic period. This paper proposes an ACA(Adaptive Collision Avoidance) algorithm adapting the initial backoff range to the undergoing collision variations. It also introduces a mathematical model to predict the performance of ACA algorithm added to IEEE 802.15.4. With only small deviations from corresponding simulations, our analytical model shows that ACA technique can improve the throughput of IEEE 802.15.4 by up-to 41% maximally in addition to shortening the packet delays.

This study aims not only to examine the globalization, imformationization, and networking as background of knowledge-information-based society, but also to clarify the research fields of 'geography of knowledge' and further research themes for economic geography in a knowledge-information-based society. As a result of globalization, the degree of regional disparity, which had decreased with neoliberal policy in Europe and America in 1980's, has increased in early development states such as China and Eastern European countries. In opposition to the globalization that has led to increasing regional disparities at a global scale, many scholars argue that grassroots globalization or globalization from below is needed. Based on a pessimistic view on globalization, many maintain that unequal access to information has enlarged the gap between rich and poor. They also argue that the study of the geography of poverty is crucial in oder to solve the problem of bipolization. According to the world system theory, spatial grasp of commodity chains, actors' diversities, flows towards innovation in learning knowledges, and geographical, organizational, and institutional proximities are intertwined. Because these elements make significant influences each other in social networks, the interrelationships among those elements should be carefully considered. A 'geography of knowledge' deals with manufacturing, finance and service, media, cultural, and creative industries. Former researches in economic geography have tended to deal with those industries separately without attempting to make meaningful linkages among discussions on those industries.
