The purpose of this study is to understand baby boomers' perception of and preparation for later life by analyzing essays from 80,000 hours design competition. The researchers were able to access to 62 baby boomers' essays and used thematic analysis. The results showed that the competition enabled participants to re-conceptualize the meaning of preparation for later life. Three characteristics were derived in the participants' designing their future: 1) life focused on themselves, 2) life in which work, relationship, and leisure are balanced, 3) community life which take social responsibility. All the participants stressed health and learning as key factors in preparing for later life. They also showed almost obsessiveness toward their own effort to be diligent in order to achieve their idealistic later life. Based on the findings, practical implications for preparation for later life among baby boomers are discussed.

Online education is a new domain of learning that combines distance learning with the practice of face-to-face instruction utilizing computer-mediated communication. As technology continues to develop and the needs of teachers require better access to higher learning, online graduate degree programs can be a valid alternative. Some institutions in the United States have already offered graduate degrees in music education through the online distance learning. In this study, 8 accredited online graduate degree programs in music education were identified in terms of curriculum requirement, program requirement, and admission requirement. Online programs offer considerable benefits of convenience, while their drawbacks relates to the quality of learning, feelings of weaker interpersonal interaction. More researches need in order for online music programmers to achieve higher standards of instruction and to inform other disciplines in the fields of arts education and the performing arts.

The worldwide population is aging rapidly. In this circumstance, Korean society is in need of the urgent comprehensive countermeasures that will help the elderly with their health problems and infection control in their daily life. Universal design has supportive, adaptable, accessible and safety-oriental design standards for the elderly. Is this study, we propose the guidelines of the mobile application development based on the application of the universal design for infection control in the elderly. From the perspective of the universal design, there are several important guidelines including 'generalized access', 'simple and intuitive usage', 'low physical effort', and 'visualized language' based on the KCDC(Korea centers for disease control and prevention) principles for the elderly. These findings show that the guidelines for improving the health literacy of the mobile application via universal design are necessary to enhance the health behavior of infection control for the elderly.

IEEE 802.11 WLAN(Wireless Local Area Network) standard is currently developing with increased wireless internet demand. Study trends of IEEE 802.11n for high throughput show two aspects, enhanced system throughput using aggregation among packets in MAC(Medium Access Control) layer, and better data rates adapting MIMO(Multiple-Input Multiple-Output) in PRY(Physical) layer. But, no one demonstrates IEEE 802.11n system performance results considering MAC and PRY connection. This paper adapts A-MPDU(Aggregation-MAC Protocol Data Unit) method in MAC layer and MIMO in PRY layer for IEEE 802.11n system. Consequently, Simulation results show enhanced throughput and data rates compared to existing system. Also, We use NS-2(Network Simulator-2) considering MAC and PRY connection for reality.

The vulnerability issue on IEEE 802.1x wireless LAN has been permits the malicious attack such as Auth/Deauth flooding more serious rather than we expected. Attacker can generate huge volume of malicious traffic as the same methods on existing wired network. The objective of wireless IP Traceback is to determine the real attack sources, as well as the full path taken by the wireless attack packets. Existing IP Traceback methods can be categorized as proactive or reactive tracing. But, these existing schemes did not provide enhanced performance against DoS attack on wireless traffic. In this paper, we propose a 'TTL based advanced Packet Marking' mechanism for wireless IP Packet Traceback with wireless Classification function. Proposed mechanism can detect and control DoS traffic on AP and can generate marked packet for reconstructing on the real path from the non-spoofed wireless attack source, by which we can construct secure wireless network based on AP with enhance traceback performance.

For supporting seamless service in NGN, various schemes for mobility are studying in ITU-T, 3GPP, IETF, and so on. Currently, mobility support schemes such as MIPv6, IP2, Q.MMF, IMS was introduced. However the performance analysis and comparison of all existing schemes is not examined as yet. That is, the existing mobility methods need to be compared according to same performance parameter. So, in this paper, we investigate and compare the performances of MIPv6, IP2, Q.MMF on latency during location registration. The latency in location registration is consider as cost and time. Then, the performance analysis of Q.MMF Case1 has shown the best performance as it is measured the minimum cost and time. Q.MMF Case1 is the location registration process in case that MT moves within a local network. As LLM in a access network manages the location of MT in this case, Q.MMF Case1 has lower location cost and time than other cases.

In the post-genomic era, researches on proteins as well as genes have been increasingly required. Particularly, work on protein-protein interaction and protein network construction have been recently establishing. Most biologists publish their research results through papers or other media. However, biologists do not use the information effectively, since the published research results are very large. As the growth of internet, it becomes easy to access very large research results. It is significantly important to extract information with a biological meaning from varisous media. Therefore, in this research, we efficiently extract protein-protein interaction information from many open papers or other media and construct the database of the extracted information. We build a protein network from the established database and then design and implement various pathway analysis algorithms which find biological meaning from the protein network.

This study will analyze the meaning and the characteristic of advertising system in Facebook, one of the leading social platforms. This study focuses on finding the trend of mobile advertisement and observing Facebook users behavior. During 30seconds, the researcher observed the behaviors of 50 male and female university students which they access and use their own Facebook individually. After the observation, the researcher did an in-depth analysis based on offline discussion with tested participants. As a result, it can be classified in positive causes and negative causes of the advertisement. There are 3 positive causes; native advertisement effect, acquaintance effect, and big data effect and they help people watch the advertisement positively. 1.5-3 times per second high speed scroll behavior (Finger effect) is the main negative cause and it help users escape from the advertisement easily. These positive and negative causes have an interactive synergy which reduces user stress and makes people enjoy ad more than other media. Finally, both of them cause making Facebook a better environment for the advertisement.
