  • Integral imaging is a three-dimensional display technique which has 100 years of history. The method is characterized by offering full parallax, almost-continuous viewpoints and easiness of moving picture display. In this paper, the history of the method is briefly explained and overview of its current status is provided.

  • Convertible authenticated encryption (CAE) schemes enable the signer to send a confidential message and its corresponding signature to the designated recipient. The recipient can also convert the signature into a conventional one which can be verified by anyone. Integrating the properties of self-certified public key systems, this paper presents efficient and computationally indistinguishable self-certified CAE schemes for strengthening the security of E-Commerce applications. Additionally, we also adapt the proposed schemes to elliptic curve systems for facilitating the applications of limited computing power and insufficient storage space. The proposed schemes are secure against known existential active attacks, satisfy the semantic security requirement, and have the following advantages: (i) No extra certificate is required since the tasks of authenticating the public key and verifying the signature can be simultaneously carried out within one step, which helps reducing computation efforts and communication overheads. (ii) In case of a later dispute, the recipient can convert the signature into an ordinary one for the public arbitration. (iii) The signature conversion can be solely performed by the recipient without additional computation efforts or communication overheads. (iv) The recipient of the signature can prove himself, if needed, to anyone that he is actually the designated recipient.

  • The purpose of the study was to investigate types of uniforms which were considered as appropriate, functional, and/or power look. Also, the possibility of acceptance of a pantsuit for uniforms was examined. For the study, a questionnaire was developed by the researcher. The subjects were asked to select appropriate, function Al, or power look among combinations of: 1) two types of jackets with different shoulder width (natural, wide) and two types bottoms(pants, skirt) : 2) blouses with three different collars (ribbon, convertible, tailored) and two types of bottoms (pants, skirt) . The majority (89%) of subjects were 185 male and 182 female white-collar workers. For the ststistical analysis, Chi-square, one-way ANOVA, and t-test were used. The results of the study were: 1) For a uniform, a skirted suit was considered as being appropriate and powerful, and pants were regarded as being functional. 2) A jacket with natural shoulders was viewed as an appropriate and functional uniform, and a jacket with wide shoulders as power look. 3) A blouse with a convertible collar was regarded as an appropriate and functioal uniform, and a tailored collared-blouse evaluated as power look.
