Preferred orientation of MgO protection layer is controlled via adjusting diffusion of adatom between (111) plane with highest neighbor atoms and (200) plane with lowest neighbor atoms. The diffusion of adatom could be modulated by the factors such as substrate temperature, deposition rate, and extra energy applied on adatom like ion beam energy.

The purpose of this study was to investigate the relationships between life style and clothing purchase intention and purchase criteria in internet shopping-mall of male and female consumers. The subjects were 275 internet users (male: 164, female: 111). The results of the study were as follows. Five factors of life style derived by factor analysis:'Digital Orientation','Economy Orientation','Positive Activity','Fun Orientation', and'Home Orientation'. The dress types to be based on the purchase intention in internet shopping-mall was classified into four dimensions by factor analysis: Casual Wears & Single Item Clothes','Formal Wears','Miscellaneous Goods', and'Underwears ＆ Night Clothes'. Internet users showed relatively high purchase intention in casual wears & single item clothes and miscellaneous goods. Clothing purchase intention in internet shopping correlated significantly with home orientation in males, and with digital orientation in females. Subjects high in fun orientation placed importance on design as clothing purchase criteria. Males high in positive activity placed importance on price, color, sewing, brand, and wearing appearance. Females high in digital orientation believed design, color, material, refundment condition, and fashionability were important as purchase criteria. The level of digital orientation of dress purchasers in internet shopping-mall was higher than that of non-purchasers in case of males, and that of fun orientation was higher than that of non-purchasers in case of females. The present findings suggest that life style such as digital orientation and home orientation appeared to be important in predicting the clothing purchase intention in internet shopping mall.

Morphological control on hydroxyapatite crystals has attractive prospects in research to clarify the effects of crystal planes on biological performance. Hydrothermal processing is known as a typical type of processing for fabricating well-grown crystals with unique morphology. The purpose of the present study is to examine the feasibility of well-crystallized crystals with oriented structures through hydrothermal treatment of calcite. A single crystal of calcite was applied to hydrothermal treatment in a phosphate solution at $160^{\circ}C$. Rod-shaped hydroxyapatite crystals with micrometer-size were formed on the {100} face of calcite after treatment, while nanometer-sized hydroxyapatite crystals were formed on the (111). The hydroxyapatite crystals formed on each plane were not morphologically changed with increasing treatment periods. An oriented structure of rod-shaped hydroxyapatite was constructed after hydrothermal treatment of {100} planes on the calcite single, while such orientation was not observed on the (111) plane after the treatment. The layer of hydroxyapatite formed on the {100} plane was thicker than that of the (111) plane. The {100} plane of calcite shows a higher reactivity than that of the (111) plane, which results in rapid crystal growth of hydroxyapatite. The difference in the morphology of the formed hydroxyapatite was governed by the reactivity of each crystal plane exposed to the surrounding solution.

Surface potential and growth processes of hexadecanethiol (HDT) self-assembled monolayers (SAMs) on Au(111) surfaces were examined by Kelvin probe method and scanning tunneling microscopy. It was found that surface potential strongly depends on surface structure of HDT SAMs. The surface potential shift for the striped phase of HDT SAMs chemisorbed on Au(111) surface was +0.45 eV, which was nearly the same as that of the flat-lying hexadecane layer physisorbed on Au(111) surface. This result indicates that the interfacial dipole layer induced by adsorption of alkyl chains is a main contributor to the surface potential change. In the densely-packed HDT monolayer, further change of the surface potential was observed, suggesting that the dipole moment of the alkanethiol molecules is an origin of the surface potential change. These results indicate that the work function of a metal electrode can be modified by controlling the molecular orientation of an adsorbed molecule.

Growth characteristics and microstructure of AlN thin films grown by plasma assisted molecular beam epitaxy on Si substrates have been investigated. Growing temperature and substrate orientation were chosen as major variables of the experiment. Reflection high energy electron diffraction (RHEED), X-ray diffraction (XRD), atomic force microscopy (AFM) and transmission electron microscopy/diffraction (TEM/TED) techniques were employed to characterize the microstructure of the films. On Si(100) substrates, AlN thin films were grown along the hexagonal c-axis preferred orientation at temperature range 850-90$0^{\circ}C$. However on Si(111), the AlN films were epitaxially grown with directional coherency in AlN(0001)/Si(111), AlN(1100)/Si(110), and AlN(1120)/Si(112) at 85$0^{\circ}C$ and the epitaxial coherencry seemed to be slightly distorted with increasing temperature. The microstructure of AlN thin films on Si(111) substrates showed that the films include a lot of crystal defects and there exist micro-gaps among the columns.

Surface structure and molecular orientation of self-assembled monolayers (SAMs) formed by the spontaneous adsorption of tetrahydrothiophene (THT) and thiophene (TP) on Au(111) were investigated by means of scanning tunneling microscopy (STM) and carbon K-edge near edge X-ray absorption fine structure (NEXAFS) spectroscopy. STM imaging revealed that THT SAMs have a commensurate (3 ${\times}\;2\sqrt[]{3}$) structure containing structural defects in ordered domains, whereas TP SAMs are composed of randomly adsorbed domains and paired molecular row domains that can be described as an incommensurate packing structure. The NEXAFS spectroscopy study showed that the average tilt angle of the aliphatic THT ring and $\pi$-conjugated TP ring in the SAMs were calculated to be about $30^o\;and\;40^o$, respectively, from the surface normal. It was also observed that the $\pi$* transition peak in the NEXAFS spectrum of the TP SAMs is very weak, suggesting that a strong interaction between $\pi$-electrons and the Au surface arises during the self-assembly of TP molecules. In this study, we have clearly demonstrated that the surface structure and adsorption orientation of organic SAMs on Au(111) are strongly influenced by whether the cyclic ring is saturated or unsaturated.

ZnO thin films were deposited on Al and Pt electrodes by an RF reactive sputtering system for the fabrication of FBAR (film bulk acoustic wave resonator), and the effect of thermal treatment temperature on their c-axis preferred orientation was investigated. SEM experiments show that columnar structure of ZnO thin films were grown with c-axis normal to electrode material, and XRD experiments show that both ZnO films were grown with (002) plane preferred orientation, but larger diffraction peak was observed with Pt electrode. The peak intensity increased with higher thermal treatment temperature, but c-axis preferred orientation was diminished. The surface roughness of Al thin film was higher than that of Pt, and these affect the surface roughness of ZnO film deposited on the electrode. Though the preferred orientation with respect to Pt(111) plane was improved with higher thermal treatment temperature, this could not improve the c-axis orientation of ZnO film.

Since companies are increasingly aware of the importance of upstream and downstream organizations to their performance, companies' leaders would also like to influence operations with supply chain partners. This paper aims to study the SCM performance and the influencing factors, that is Buyer's leadership and Vendor's relationship-orientation. Also, I try to examine the mediating effect of relationship-orientation between leadership and SCM performance. The results of this study can be summarized as follow; (1) The charismatic trait and individual consideration in transformational leadership factors, and contingent reward in transactional leadership factors positively effected to the relational-orientation. But intellectual stimulation and management-by-exception did not effected to relational-orientation. (2) Only contingent reward in transactional leadership factors was significantly related to the SCM performance. (3) Relational-orientation mediated between SCM leadership and SCM performance.

Multiple sales promotions for one product can be simultaneously offered. For instance, marketers can offer a premium along with a price discount. In the present research, we primarily focus on offers containing both a bonus pack and a price discount. In particular, this research examines whether consumer evaluations of offers containing both a bonus pack and a price discount (i.e., BP + PD offers) vary according to consumers' saving orientation. Specifically, we predict that for consumers with strong (vs. weak) saving orientation, offers containing the high PD but low extra amount of BP will be more favorably evaluated than offers with a high extra amount of BP but low PD. A series of two experimental results show that consumers' saving orientation moderates their evaluations of BP and PD offers, which supports the prediction. The findings imply that marketers can evoke more positive consumer responses to BP and PD offers, considering individual differences such as saving orientation.

The effect of H$_2$ content in Ar sputtering gas on exchange coupling field(H$_{ex}$) for NiFe/FeMn interface was studied. When NiFe layer of Si(100)/Ta(50 $\AA$)/NiFe(60 $\AA$)/FeMn(250 $\AA$)Ta(50 $\AA$) was deposited at 8% H$_2$ in sputtering gas, the maximum exchange coupling field(H$_{ex}$) and minimum coercivity(H$_{c}$) were obtained. When Si(100)/Ta(50 $\AA$)/NiFe(60 $\AA$)/FeMn(250 $\AA$)/NiFe(70 $\AA$)/Ta(50 $\AA$) was deposited at 5% H$_2$ in sputtering gas, the maximum exchange coupling field(H$_{ex}$) of 148 Oe was obtained. The (111) preferred orientation and grain size of underlayer NiFe were increased and the internal stress was reduced by H$_2$ in sputtering gas. And the (111) preferred orientation and grain size of FeMn layer were also increased.d.ased.
