The variation of the directional properties of an image is used to extract the iris code for human identification. In order to conserve the original information while minimizing the effect of noise, scale-space filtering is applied. Resulting binary codes have been tested on a set of 272 iris images obtained from 18 persons.

When the hydrodynamic coefficients of the ship maneuvering equation are estimated by captive model test, it is difficult to take account of the scale effect between model and full scale ship. This scale effect problem can be overcome by processing the sea trial data with system identification. Extended Kalman filter is used as a system identification technique for the modification of the simulation equation as well as the estimation of hydrodynamic coefficients. The phenomena of simultaneous drifting of linear coefficients occur. It is confirmed that two coefficients in each pair-($Y_v$', $Y_r$' -m' u'), ($N_v$', $N_r$' )-are simultaneously drifting and all 4 coefficients are simultaneously drifting together. Particularly simultaneous drifting of 2 coefficients in each pair is more significant. It is also shown that the simultaneous drifting of 4 coefficients can be reduced by choosing the input data which have the random v'/r' curve and 4 coefficients are estimated within 2-4% error, which may be noise level. So, it is recommended to operate the rudder randomly in sea trial or model test for the application of system identification technique.

Mechanical anchorage devices are generally tested in the laboratory and may be analyzed using the finite element method. These devices are composed of many components interacting through diverse contact interfaces. Generally, a Coulomb friction law is sufficient to take into account friction between smooth surfaces. However, in the case of mechanical anchorages, a gripping system, named herein the wedge-tendon system, is used to anchor the prestressing tendon. The wedge inner surface is made of a series of triangular notches designed to grip the tendon. In this particular case, the Coulomb law is not adapted to simulate the contact interface. The present paper deals with a new constitutive contact/gripping law to simulate the gripping effect. A parameter identification procedure, based on experimental results as well as on a finite element/neural network approach, is presented. It is demonstrated that all parameters have been selected in a satisfactory way and that the proposed constitutive law is well adapted to simulate the wedge gripping effect taking place in a mechanical anchorage device.

Today the concept of corporate social responsibility has become an essential element for coexistence of corporations and the society. In this study the impact of four responsibilities of business organizations proposed by Archie Carroll (economic, legal, ethical, and discretionary) on customer loyalty through the mediating effect of trust and company-consumer identification is analyzed. A questionnaire survey was conducted for four well-known Korean companies (Dong Suh Food, LG Household and Health Care, Samsung Electronics, and Hyundai Motor). After factor analysis, legal and ethical responsibilities were grouped as the same factor, thus three social responsibilities were finally used for hypotheses testing. Major findings were as follows: First, economic responsibilities had positive impact on honesty trust, professionalism trust, favorableness trust, and company-consumer identification, Second, legal/ethical responsibilities were found to have significant effects on honesty trust, favorableness trust, and company-consumer identification. Third, in the case of discretionary responsibilities, professionalism trust, favorableness trust, and company-consumer identification were revealed to have a significant positive relationship. Fourth, only two trust variables (honesty and professionalism) and company-consumer identification had positive influence on the loyalty of customers. These findings are expected to help decision makers to set up corporate objectives and choose action items for corporate social responsibility. At the last part, implications of the study and future research directions were discussed.

Purpose - This research aimed at exploring the mediation role of Muslim's identification with halal brand in the effects of the congruity between Islamic self and halal brand and Islamism commitment on the loyalty to the brand. Research design, data, and methodology - A single factor design was employed. A total of 199 undergraduate, graduate students or office workers in Bangladesh participated in main survey to finish the questionnaire. Structural equation model analysis was used to verify hypotheses. Results - The results of verifying hypotheses were as followings. First, the Muslim's identification with halal brand positively affected on the loyalty to the halal brand. Second, Both Muslim's commitment to Islamism and the congruity between Islamic self and halal brand positively affected on the identification with the halal brand. Third, mediation analysis showed the partial mediation role of Muslim's identification with halal brand in the effects of the Islamism commitment on the loyalty to the halal brand, and there was the full mediation role of the Muslim's identification in the effect of the congruity on the loyalty. Conclusions - Marketers should build the congruity between Islamic self and their halal brand and promote Islamism commitment to induce the loyalty to the halal brand from Muslim.

Character identification is illustrated in terms of game players' altered self-perception during gameplay. Research has shown that players' identification with game characters resulted in game players aligning their attitude with game character. This study investigates the relationships among control, ownership, character customization, identification, flow with game charater, and the impact on game players' behavior toward item purchase and play intention. Empirical results showed that character ownership and character customization significantly predicted use-character identification, but the impact of character control was not supported. In addition, the positive relationships between identification and flow was supported.

This study examines the effectiveness of brand awareness, brand image and brand identification on brand loyalty for the Nike brand. The subjects of this study were 336 elementary school boys. The statistical methods used for this study were factor analysis, Cronbach's alpha analysis, confirmatory factor analysis and path analysis with SPSS 19.0 and AMOS 19.0. The results of this study were as follows. First, brand awareness had a direct effect on brand image and brand loyalty. Brand awareness also had an indirect effect on brand loyalty. Second, brand image directly or indirectly influenced brand loyalty as well as directly influenced brand identification. Third, brand identification directly influenced brand loyalty. The $5^{th}$ grade group and $6^{th}$ grade group had different paths; however, the most powerful path was the same as brand awareness to brand image. The results of this study will help fashion companies understand the importance of new consumer groups in their early teens or elementary school.

Objectives : The aim of this experiment is to find out relationship between the effect of cosmetics and 4 types of pattern identification about fluid-humor, which are based on the general idea of traditional oriental medicine, Qi-Blood and deficiency-excess. Methods : Korean female volunteers in good health (n=25, $23.12{\pm}2.83$) participated in this experiment. Three Korean medical doctors classified them into 4 groups: Blood-deficiency: group A; Blood-excess: group B; Qi-deficiency:group C; Qi-excess:group D). Cosmetics that contains herb extract for Blood deficiency were given to all volunteers and they used the cosmetics for 4 weeks. Volunteers were assessed non-invasively with the skin measuring devices before and after using cosmetics. And we analyzed the correlation of skin physiological parameters with 4 groups. Results : Three doctors diagnosed participants and classified them into 4 groups ; group A(n=8),group B(n=7), group C(n=3), group D(n=5) as highest score. After 4 weeks, facial skin moisture showed no significant difference in comparison between 4 groups. Sebum showed significant increase in Group A and significantly decreased Group B. Measurement of facial skin elasticity tended to increase in Group A, C, D but skin elasticity was decreased significantly in Group B. Conclusions : In case of a group that pattern identification about fluid-humor corresponds to herb extract in cosmetic, skin improving effect was better than the other group that pattern identification oppose to properties of herb in cosmetic. Therefore, from the view of traditional oriental medicine, it is very important to understand user's pattern of identification or physical conditions and properties of herbs in cosmetics on the matter of safety and efficacy.
