  • We study theoretical aspects of one-dimensional cellular automata over GF(q), where q is a power of a prime. Some results about the characteristic polynomials of such cellular automata are given. Intermediate boundary cellular automata are defined and related to the more common null boundary cellular automata.

  • In this study, analyzed principle about stream cipher that is formed to Cellular Automata foundation. Cellular Automata can embody complicated and various principle with simple identifying marks that is State, Neighborhood, Transition Rules originally. Cellular Automata is hinting that can handle encipherment smoothly using transition rule. Create binary pad (key stream) by Cellular Automata's transition rule 30 applications in treatise that see therefore, and experimented ability of encryption and decryption because using stream cipher of symmetric key encryption way of password classification.

  • In Korea, the number of cellular phone user rapidly increases. As cellular phone users increase, the crime related cellular phone terminal and contents becomes a newly emerging serious social problem. However, the study on cellular phone crime is very rare in Korea now. The purpose of this study are an examination of the concept, types and the current condition of cellular phone crime, and a suggestion for efficient countermeasures of cellular phone crime.

  • Recently, energy-efficient cellular transmission has received considerable research attention to improve the energy efficiency of wireless communication. In this paper, we consider a cellular network consisting of one base station (BS) and multiple user terminals and explore the network coding for enhancing the energy efficiency of cellular downlink transmission from BS to users. We propose the network coded cellular transmission scheme and conduct its energy consumption analysis with target outage probability and data rate requirements in Rayleigh fading environments. Then, the energy efficiency in Bits-per-Joule is further defined and analyzed to evaluate the number of bits delivered per Joule of energy cost. Numerical results show that the network coded cellular transmission significantly outperforms the traditional cellular transmission in terms of energy efficiency, implying that given a Joule of energy cost, the network coded cellular transmission scheme can deliver more bits than the traditional cellular transmission.

Relationships on Parents' Authoritative Parenting Attitude, Adolescent's Emotional Bonding with Parents and Cellular Phone Addiction: The Mediating Effect of Impulsiveness (청소년자녀 부모의 권위주의적 양육태도, 부모와의 정서적 유대와 휴대폰 중독 - 충동성의 매개효과를 중심으로 -)

  • The purpose of this study is to find the correlation between authoritative parenting attitudes, emotional bonding of adolescents with parents, impulsiveness and cellular phone addiction. The paper will also explore the mediating role of impulsiveness between adolescents' emotional bonding with parents, authoritative parenting attitudes and cellular phone addiction. The subjects were made up of 237 adolescents. The data were analyzed with frequency, ANOVA, Pearson's correlation and structural equation modeling by PASW and AMOS. The instruments used were Lee et al. (1997) Parenting Attitude, Hudson (1982) Child's Attitude Toward Parent (CATP), Lee (2001) BIS (Barnett Impulsiveness Scale) and Lee (2008) Cellular Phone Addiction. The major findings were as follows: the sex of the adolescents was significantly different with cellular phone addiction and their family economic status was significantly different with adolescents' emotional bonding with parents and cellular phone addiction. Authoritative parenting attitude was negatively correlated with adolescents' emotional bonding with parents and positively correlated with impulsiveness and cellular phone addiction. Emotional bonding of adolescents with parents was negatively correlated with impulsiveness and cellular phone addiction. Adolescents' emotional bonding with parents influenced impulsiveness and cellular phone addiction negatively, and impulsiveness mediated the effects of adolescents' emotional bonding with parents, authoritative parenting attitude and cellular phone addiction. Authoritative parenting attitude influenced adolescents' impulsiveness and cellular phone addiction positively, but impulsiveness influenced cellular phone addiction positively. In conclusion, it is important to intervene in adolescents' cellular phone addiction through special education programs and counseling to build adolescents' emotional bonding with parents and to reduce impulsiveness.

  • Currently, there are many efforts underway to provide Internet service on integrated wireless and wired networks. Supporting IP mobility is one of the major issues to construct IP based wireless network. Mobile IP has been proposed to solve the IP Mobility problem. But, in processing frequent handoffs in cellular based wireless access network, Micro mobility protocols have been proposed to solve these problems. Micro mobility protocols proposed the Cellular IP, HAWII, and Hierarchical Mobile IP. Cellular IP attracts special attention for it's seamless mobility support in limited geographical areas. New BS must be known to occur begging of handoff in Cellular IP indirect handoff. Therefore during perceiving of hanoff, packet loss or packet duplication still can occur in Cellular IP indirect handoff, which results in the degradation of UDP and TCP performance. In this paper, we propose a enhanced indirect handoff scheme for Cellular IP. Proposed handoff scheme is using a crossover node to minimize the signalling procedure and using a buffering to minimize the packet loss or packet duplication.
