사춘기에 접어든 아이들과 겨울방학을 잘 지내기 위해서는 어떤 마음의 준비가 필요할까? 점점 더 이해하기 어려워지는 아이를 다독이고, 아이와 말싸움을 하면서 속상해진 내 마음은 어떻게 다스려야할까.

In this study, various thermodynamic and hydrodynamic parameters characterizing the solution properties of polyethylene ionomer particles in water were determined at $30^{\circ}C$ by means of light scattering and viscosity measurements. Based on the experimental data, we investigated the solution behavior of three kinds of polyethylene ionomers, which are different in composition of the pendant ionic groups of COOK, COOH and $CONH_{2}$, and characterized their particle properties. Ionomers containing 7.6 mol% potassium salt only behave as flexible coils in a relatively good solvent state. On the other hand, two ionomers containing 3.8 mol% amide group together with potassium salt form the compact particles. In addition, the concentration dependence of the effective diffusion coefficient $(D_{eff})$ and the reduced viscosity of the latter ionomers showed the opposite trend from the former, indicating that the composition of the pendant ionic groups have a great influence on the interparticle interaction of ionomers formed in water.

The electronic transactions over the Internet are growing across the world recently. There have been a lot of identity theft incidents during these online transactions nowaday. Therefore, a high level of identity proofing shall be carried out when using online services to deal with these matter. To prevent this kind of incident, i-PIN was introduced in Korea, which is used as an Internet Personal Identification Number. The i-PIN is designated to provide an online identification of the Internet users. As such, the unique identification numbers are provided to the internet service providers. This paper is to analyze the capabilities that the i-PIN provides, to propose the assurance security model for i-PIN. Furthermore, the security analysis results are presented. The result of this paper can be applicable to improve the applicabilities of the i-PIN.

Given that the current Idol fandom has been enormously affected by the development of digital technology such as the Internet, mobile or social media, this study explored how generational fandom culture has been shifted depending on the fandom's use of differential online platforms and services, i.e., online community vs. social network services. The survey results indicate that 3^rd generation fandom showed significantly greater intimacy, greater attachment/worship, greater similarity toward Idol stars as well as greater fandom loyalty and greater fandom identity than 1^st and 2^nd generation fandom. Similarly, compared to online community centered fandom, social network centered fandom showed greater intimacy, greater attachment/worship, greater similarity as well as greater fandom loyalty and identity than community-centered fandom.
