Mental health issues related to depression and individual's patterns of interest impact development. This study is to identify patterns of interest and their effects on depressive symptoms in young adults. This cross-sectional study involved 40 participants. The participants were assessed for depressive symptoms, patterns of interest in daily life, and social participation. The depressive symptoms and patterns of interest were assessed by a well-trained interviewer using a face-to-face method. Descriptive statistics, correlation analysis, and logistic regression analysis were implemented using SPSS 22.0. In terms of depressive symptoms, 32.5% of participants reported no depression, while 67.5% were depressed. When comparing interest patterns from the past, present, and future, the degree of depression was significantly correlated with interests in the past (p<.05). The effect of patterns of interest on depressive symptoms was not statistically significant (p>.05). Participation in a variety of activities can help prevent depressive symptoms. Participation in activities of interest can, therefore, be of great help during middle- and late-adult development.

Recently, there're lots of interest in UCC, user-created contents, in the Internet market. the sites providing only the UCC service are beginning to appear. I am going to find out their strengths and weaknesses and the future directions. I started this study by discussing the direction of the UCC business. Now we see that the video UCC contents in the portal sites are growing gradually.

Purpose: The purpose of this study was to identify the trends of nurses' stress based on the last 10 years of international research and to suggest directions for future research. Methods: Fifty three articles between 2002 and 2011 were selected using key words such as 'nurse' and 'stress' from the PubMed and CINAHL. Results: The number of experimental studies increased. The nurses from the various fields were studied. Most studies used a reliable and valid tool for measuring stress of specific nursing staff. The Internet survey was recently used for a data collection method. Significant variables correlated with nurses' stress were categorized into 8 domains: Individual susceptibility, quantitative workload, qualitative workload, physical environment, organizational factors, and interpersonal conflict. Conclusion: In Korea, the next phase of research on nurses' stress needs to consider the experimental study design to find more specific causal relationships. Also, it is necessary to develop the nurses' stress tool for reliable and valid measurement.

Recently, demage of denial of service attack and worm attack has grown larger and larger every year. But Research of harmful traffic detection is not sufficient when the IPv4 environment is replaced with the IPv6 environment in near future. The purpose of this paper is attact detection which has been detected harmful traffic monitoring on the IPv6 using the Internet management protocol SNMP.

In the age where the Internet changes everything, even the earth has become flat. The boarders between nations, locations, times, and industries are not meaningful, and no single company can do the whole process well. Therefore, various types of 'Value network' and 'Relation web' emerge for moving first and learning fast. Both the relationship maturity model (RMM) proposed and the partnership management initiatives at SKT demonstrate that the concept is important, and that the final goal can be reached only through a series of critical outcome at each phase. In particular, recognizing as core infrastructures various online/offline channels, deep trust, and rich communications is an important finding for a successful relationship management. Also, related literatures suggest the following key factors to be influential in more than two phases: professionalism including expertise, similarity, channel infrastructure, trustful/trustworthy, and absorptive capacity. Based on these findings, future efforts need to be put on the research & development of related measurement and management tools. It is hoped that more dance with their partners through these efforts.

The Internet has made a huge impact on the way we, as humans, communicate. During the last decade a series of new communication mediums have emerged and communication protocols have come and gone. This puts new requirements on the development process and architecture of the communication platforms, operated by communities, in order to proactively ensure support for future communication protocols. Even further, additional requirements are added when the software itself will be maintained by a community. In this paper we explore the world of Open Source Software. We present our suggestions of usable design-principles and our process in developing a sustainable information system.

The Photovoltaic(PV) generation system is a promising source of energy for the future. Since the need for renewable energy has been increased, the research of PV generation system has also been progressed. The main subject of this paper is about making the more useful real-time monitoring program to get and save the data from photovoltaic generation system of 30kW grid-connected. Therefore, it uses LabView for this real-time monitoring program.

최근 사물인터넷에 대한 관심이 증가함에 따라 미래인터넷에 대한 연구가 증가하고 있다. 각기 다른 사물인터넷을 연결하기 위하여 다양한 네트워크 인프라가 필요하며, 사용자뿐만 아니라 다양한 네트워크 자원에서 요구하는 서비스나 콘텐츠 등이 증가하고 있다. 이에 따라 이들을 식별하기 위한 통일된 식별 체계가 필요하다. 이를 위하여 미국에서는 NDN에 대한 연구가 진행 중이며, 이외에도 MobilityFirst, XIA와 같은 프로젝트성 연구들이 활발히 이루어지고 있다. 따라서, 본 논문에서는 기존의 연구들을 보완하고 새로운 미래인터넷에 확장 가능한 통합된 Name-Identifier-Locator 프레임워크를 제안한다.

Multiprotocol Label Switching is an initiating IETF that integrated Layer2 information network links(bandwidth, latency, utilization) to Layer 3(IP) with a particular autonomous system(or ISP) in order to simplify and improve IP-packet exchange. MPLS gives network operators a grate deal of flexibility to divert and route traffic around link failures, congestion, and bottlenecks. The MPLS has advantages that will be able to solve existing problem of Network that ISP have had IP, QoS, Gigabit forwarding and traffic engineering. The purpose of this study is to measure Access-list and the capacities of PE Router that would operate as MPLS. Many ISP using MPLS service to handle high-speed internet traffic with apply to firewall in future.

현 네트워크의 한계를 극복하고, 미래사회의 기반으로서의 역할을 할 수 있는 네트워크인 미래 네트워크에 대한 연구가 최근 활발히 진행되고 있다. 이러한 미래 네트워크에 대한 시도들이 이론으로만이 아니라 실제 네트워크상에서 구축되기 위해서는 미래 네트워크를 위한 테스트베드가 필요하다. 특히 미래 네트워크 테스트베드는 현재 네트워크와 공존뿐만이 아니라, 다양한 미래 네트워크 시도들을 적용시킬 수 있는 형태로 구성되어야 의미가 있다. 하나의 공유인프라에 다수 개의 독립적인 네트워크를 구성해 주는 기술이 바로 네트워크 가상화이며, 이는 미래네트워크 실험 인프라를 구현하기 위한 핵심 기술 중의 하나이다. 본 논문에서는 네트워크 가상화 기술의 동향을 분석해보고 미래인터넷 테스트베드에 대하여 고민해 보고자 한다.
