The film music in the 1940s is characteristic of its functional role of afterward crime movie and for expressed theme of scene to causing tension by encompassing the situational description of the scenes as well as psychological struggles of characters within the realm of musical techniques. This study demonstrates the process of change of theme music that expresses time-dependent plot development in Double Indemnity in which Miklos Rozsa participated as a music director and the result verifies the hypothesis that stimulate the senses and induces increased for the absorbed in the scene musical elements can be adopted as a symbolic means to emotions in movies.

With role-based access control, access decisions are based on the roles that individual users have as part of an organization. In this paper, we propose a new RBAC model that a user delegate a permission to another user with function-unit for practical organization. A function-unit delegation is more safe than existing delegations on RBAC model. And FuRBAC model has a authentication to supervise security problems.

In this paper, we proposed the dual curved lens of concave type. HDPE (High Density Polyethylene) used to fabricate the dual curved lens. The dual curved lens consisted of two concave structures. Role of two concave structures is to beam uniform and expansion. A small concave structure has the greater curvature than big concave structure. The dual curved lens will apply to millimeter imaging system. We measured the dual curved lens performance using 250 GHz VDI source. And we simulated the dual curved lens using ZEMAX. Fabricated lens have a good performance for beam uniform and expansion.

This study aimed to examine the effect of bicultural acceptance attitudes in Korean culture and mother's countries, which are sub-factors of multicultural adolescents' bicultural acceptance, on their intention of school dropout through self-esteem. For the analysis, the 1,105 subjects were selected from the 8th(2018) the Multicultural Adolescents Panel Study(MAPS). The data collected were analyzed by various research methods including correlation analysis, regression analysis and sobel test. The main results are as follows. First, bicultural acceptance of multicultural adolescents reduced their intention of school dropout. Second, self-esteem had a partial mediating effect in the causal relationship between multicultural adolescents' bicultural acceptance in Korean culture and intention of school dropout. Third, the effect of bicultural acceptance in mother's countries of multicultural adolescents on intention of school dropout was completely mediated by their self-esteem. On the basis of the findings, practical programs to decrease the intention of school dropout and to enhance self-esteem of multicultural adolescents were suggested.

Polyurethane(PU)은 segmented 블록공중합체로써 상온보다 높은 유리전이온도(glass transition temperature, Tg)를 갖는 hard segment(H.S)와 상온보다 낮은 Tg를 갖는 soft segment (S.S)로 구성되어 있다. 이들 두 segment간의 열역학적 불친화성으로 인해 미세 상분리 구조를 갖는다$^1$. 그 결과 hard segment-rich hard domain과 soft segment-rich soft matrix의 구조를 이룬다. 이중 hard domain(HD)은 상온에서 glassy한 성격을 띄므로 물리적 가교점과 충진제의 역할을 하며 soft domain(SD)은 rubbery한 성질을 가지므로 polurethane에 탄성을 부여하는 역할을 한다.
