There are two elements of security policy that can have a bearing on its effectiveness: content and form. While the content of the security policy has been investigated extensively in the most of the previous studies, there is very little literature on the form of the security policy. Since the form of the policy influences its success, it is important to understand how to articulate the form of a security policy. Thus, the aim of this study is to investigate the relationship between security form and policy compliance of employees. Research results find that dimensions of security form have effect on attitude towards security compliance, subjective norm, perceived behavioral control, and perceived response costs, and besides attitude towards security compliance and subjective norm have an effect on persistent security compliance intention. The conclusions and implications are discussed.

Recently, as the dimensions of energy carriers increase, especially in draft, a reliable prediction of the ship motions at finite depths of water becomes necessary. The purpose of this paper is to probe the effect of finite water depth on the hydrodynamic forces and ship motions, particularly heave and pitch, in longitudinal regular head waves, by comparing the experimental value of Freakes and Keay with the author's theoretical value obtained by applying the modified strip theory to the Mariner class ship. It is confirmed that generally the hydrodynamic coefficients in the equations of motion increase with decreasing water depth, and the wave exciting forces and moments decrease with decreasing water depth. Amplitudes of heave and pitch in longitudinal regular head waves decrease as the water depth in the range where the length of the incident wave is comparatively long. The effects of Froude Number on the hydrodynamic coefficients increase with decreasing water depth and is more noticeable in the case of heave than pitch. In heave, generally the discrepancy between the experimental value and the theoretical value is relatively small in the case of $F_n=O$, but it is very large in the case of $F_n=0.2$. It is considered that the trend stems from the ignorance of the three dimensional effect and the other effects due to shallowness of water on the hydrodynamic coefficients in the theoretical calculation. An extension of methods for calculating the two dimensional hydrodynamic forces to included the effect of forward speed should be recommended. It is required that more experimental works in finite water depths will be carried out for correlation studies between the theoretical calculation, according tp modified strip theory, and model experiments.

In this work, transmission characteristics of read and write signal were calculated when a MRAM (magnetic random access memory) cell is operated up to 10 GHz. Test device having long read and write lines was modeled in 3 dimensions to perform a simulation. The simulation was divided into two parts, read and write operations, and S-parameters were computed utilizing FEM (finite element method) algorithm. Transmission coefficients, S$\sub$21/, for read and write operations of MRAM device which was designed for a single cell test configuration were analyzed from DC to 1 GHz and DC to 10 GHz, respectively. When the insulator thickness between the bit and sense lines was increased from 500 to 1500 ${\AA}$, 3 dB attenuation frequency was increased by 3.3 times, from 135 to 430 MHz. The length of the bit and sense lines were 600 ${\mu}$m. In addition, access time was estimated by calculating the propagation delay utilizing S-parameters.

The objective of this study is to explore the characteristic of welfare for the disabled on the focus of 'Welfare Law for the Disabled' through multiple paradigm of disability. A proper understanding of disability theory requires more than a distinction between individual and social model approaches. It is also helpful to distinguish between materialist and idealist explanations. These two dimensions are used to generate a four-fold typology. In 'Welfare Law for the Disabled of 1981', individual materialist position was dominated. In 'Welfare Law for the Disabled of 1989', individual idealist position dawned to appear. In 'Welfare Law for the Disabled of 1999' which expanded diverse community services, individual idealist position was strengthened and social creationist position started to appear. Several characteristics are found out after analysis of 'Welfare Law for the Disabled of 1999'. Individual materialist position, individual idealist position, and social creationist position are mixed. Though the goal of the law is based on social creationist position, the central policies and measures are based on individual materialist position and individual idealist position. So it is necessary to amend 'Welfare Law for the Disabled' in the direction of including social creationist position and social constructionist position.

This study aimed to examine the relationship between students' power types and the roles taken by students in school bullying situation. Four types of power relationship were identified by crossing two dimensions of power relationships among students, which are 'possibility of power acquisition,' and 'need for power acquision.' Salmivalli et al.'s(1996) six particpatants' roles taken by individual student were employed as possible roles for students in school bullying situations. Samples of 1822 cases were analyzed to test the relationships. Results showed that control type youth tend to be bullies, assistants of the bullies, or reinforcers of the bullies; both the followers of bullies and the recluse type youth tend to be victims. Surprisingly influential youth did not take any vivid roles in school bullying situations. Implications as well as suggestions were presented.

The crystal structure of piperidinothiosemicarbazide, $C_6H_{13}N_3S$, has been determined by single crystal X-ray analysis. The space group is P21/c with four molecules in the unit cell of dimensions $a=14.68{\pm}0.04,\;b=4.59{\pm}0.02,\;c=12.92{\pm}0.04{\AA}\;and\;{\beta}=109.4{\pm}0.2^{\circ}$. Three-dimensional photographic intensities were estimated visually. The structure has been solved by an interpretation of a Patterson synthesis and refined by block-diagonal least-squares methods to give a final R value of 0.14 for 378 observed independent reflections. There are two independent hydrogen bonds in the structure. One of them is of the type N-H${\ldots}$S with the length 3.28 and $3.39{\AA}$, and another is of the type N-H${\ldots}$N with the length $3.03{\AA}$. Apart from the hydrogen bonding system the molecules are held together in the crystal by van der Waals forces.

Lithium dihydrogen phosphate ($LiH_2PO_4$) powder was purchased from Aldrich Chemical Co. From the scanning electron microscope (SEM) observation, these polycrystals have dimensions in the range of $25-250{\mu}m$. The electrical conductivity was measured at a measuring frequency of 1 kHz on heating polycrystalline lithium dihydrogen phosphate ($LiH_2PO_4$) from room temperature to 493 K. Two anomalies appeared at 451 K ($T_{p1}$) and 469 K ($T_{p2}$). The electrical conductivity reached the magnitude of the superprotonic phases: $3{\times}10^{-2}{\Omega}^{-1}cm^{-1}$ at 451 K ($T_{p1}$) and $1.2{\times}10{\Omega}^{-1}cm^{-1}$ at 469 K ($T_{p2}$). It is uncertain whether the superprotonic phase transformations are due to polymorphic transitions in the bulk, surface transitions, or chemical reactions (thermal decomposition) at the surface. Considering several previous thermal studies (differential scanning calorimetry and thermogravimetry), our experimental results seem to be related to the last case: chemical reactions (thermal decomposition) at the surface with the progressive solid-state polymerization.

This paper studied the impact of CIO leadership on the IS performance. The survey was developed to measure the relationship between CIO leadership style and the IS performance. The study shows that the differences in CIO leadership style along the two dimensions of goals and modes do not cause a statistically meaningful difference in business efficiency, one of the IS performance. Contrary to the existing studies that suggest a balanced leadership is effective, this study illustrates that strategic leadership and enabling leadership are more effective in the aspects of targets and manners respectively. This study does contribute to the introduction and utilization of CIO: unlike existing studies on leadership, it proposes a new approach to classifying leadership style based on the styles exhibited by CIO's flexibly from one situation to another. It will provide companies considering appointing CIO's or already using CIO's with insights into effective CIO role. It is important to provide CIOs with position and authority to exhibit their leadership flexibly.
