Purpose - The objective of this research is to a) examine the effects of online reviews, posted on online distribution channels, on the change of consumers' attitudes and booking intention by distinguishing three types of online review valence: positive, negative and neutral review valence, and b) to investigate the combined effect of the inclination of online review and perceived usefulness of reviews on consumers' attitude change. Research design, data, and methodology - An experimental design was used by creating a mimicked hotel company's website and online reviews extracted from several online distribution channels such as online travel agencies (OTAs). A total of 414 respondents were randomly assigned to a type of review valence. Results - The results showed that the valence of positive reviews has a significant effect on the positive change of attitude and booking intention. However, the effect of the valence of negative reviews on the change of booking intention was not statistically significant compared to that of the valence of neutral reviews. Conclusions - The results offer some insights into the effect of online reviews on consumers' decision making processes and have important managerial implications for companies that operate online distribution channels in terms of their online marketing and the distribution of service products.

This study examined young children's beliefs about trait stability based on trait type and valence. Participants included 120 children (40 three-year-olds, 40 four-year-olds, and 40 five-year olds) recruited from 3 day-care-centers and 1 kindergarten in Seoul and Kyung-Ki province. Results revealed that young children's understanding of traits differed based on trait type and valence. Children demonstrated a strong belief that social-intention traits are more stable and harder to change when compared to internal-state traits. Young children's beliefs on trait stability were also strongly influenced by trait valence. They believed that negative traits are more likely to change for the better while positive traits have greater stability and are less likely to change over time.

This study examines the factors influencing custom officers' readiness for the Sales and Service Tax (SST) implementation in Malaysia. Specifically, this study examines the factors stipulated in the Theory of Organisational Readiness namely, change valence, task knowledge, and resource availability on the customs officers' readiness in terms of change commitment and change efficacy for SST 2.0 implementation. This study utilizes the questionnaire survey distributed to employees of the Royal Malaysian Customs Department (RMCD) that have undergone a significant change of tax regime from Goods and Service Tax (GST) to SST 2.0. The results show that all three factors significantly and positively influence the customs officers' readiness in terms of change commitment and change efficacy for SST 2.0 implementation in Malaysia. The findings in this study indicate that to ensure smooth SST 2.0 implementation, it is important for the customs department to give attention to the perception of the officers and provide the necessary resources. The findings of this study could assist RMCD and other custom agencies to take into account factors that influence readiness for change which indirectly affect job responsibility and performance of the organization.

The CO molecules adsorbed on Ni(111) surface is studied in the cluster approximation employing EH method with self-consistent charge iteration. The effect of CO coverage is simulated by allowing the variation of valence state ionization potentials of each Ni atom in model cluster according to the self-consistent charge iteration method. The CO coverage dependent C-O stretching frequency shift, adsorption site conversion, and metal work function change are attributed to the charge transfer between metal surface and adsorbate. For CO/Ni(111) system, net charge transfer from Ni surface to chemisorbed CO molecules makes surface Ni atoms be more positive with increasing coverage, and lowers Ni surface valence band. This leads to a weaker interaction between metal surface valence band and Co $2{\pi}^{\ast}$ MO, less charge transfer to a single CO molecule, and the bule shift of C-O stretching frequency. Further increase of coverage induces the conversion of 3-fold site CO to lower coordination site CO as well as the blue shift of C-O stretching frequency. This whole process is accompanied by the continuous increase of metal work function.

손실회피에 대한 연구는 많은 진보가 있었다. 특히 Brenner et al. (2007)은 소유손실회피 (possession loss aversion: PLA)와 유인가손실회피 (valence loss aversion: VLA)의 상황을 구분하면서 현금과 현물 (돈, 부동산)에 대한 손실 (PLA)과 잠재적으로 획득할 가치 (해외연수, 쿠폰)에 대한 손실 (VLA)에 대한 사람들의 반응이 어떻게 다른지 관찰하였다. 그러나 일상생활에서 소유와 유인가의 득과 실이 명확하게 구분되는 경우는 드물고, 대부분 소유와 유인가의 득과 실 사이에 일장일단이 있어, 결국 사람들이 평소 가지고 있는 사고방식이나 주의의 초점이 의사결정에 반영되는 경우가 더 많다. 따라서 본 연구는 사람들이 평소 어디에 주의를 기울이는지에 따라 손실회피의 반응이 어떻게 달라지는지 살펴보고자 했다. 구체적으로 자기초점을 촉진초점 또는 예방초점으로 점화한 후, 이직결정상황에서 소유와 유인가의 득실이 경쟁 (연봉증가 해외연수기간감소: P+V-, 연봉감소 해외연수기간 증가: P-V+)할 때, 이직할 것인지 여부를 결정하는 과제를 수행하였다. 결과적으로 촉진초점의 경우 소유인지 유인가 인지에 관계없이 잠정적으로 얻게 될 이익 (+)에 주의를 기울인 결과 이직하겠다는 응답이 증가한 반면, 예방초점의 경우 잠정적으로 감수할 손실 (-)에 주의를 기울인 결과 현재 회사에 머물겠다는 응답이 증가하였다. 본 연구의 결과는 소비자 및 광고심리와 마케팅분야에 폭넓은 시사점을 가진다.

Ferroelectric $HoMnO_3$ thin films were deposited on the Si(100) substrate at $700^{\circ}C$ for 2 hrs by metalorganic chemical vapor deposition (MOCVD) and post-annealed at 850oC by rapid thermal process (RTP). Electrical properties and crystalline phases of $HoMnO_3$ thin films were investigated as a function of postannealing time. Single phase of hexagonal symmetry with c-axis preferred orientation was obtained from $HoMnO_3$ thin films post-annealed at $850^{\circ}C$ for 5 min, while the c-axis preferred orientation was decreased with the increase of post-annealing time, and the thin films post-annealed at $850^{\circ}C$ for 15 min showed the mixture phases of hexagonal and orthorhombic symmetry. P-E (Polarization-Electric field) hysteresis loop of ferroelectric $HoMnO_3$ thin films was observed only for the single phase of hexagonal symmetry, but that was not observed for the mixture phases of the hexagonal and orthorhombic symmetry, which was discussed with the bond valence of Mn ion of crystalline phase. Leakage current density was dependent on the microstructure of thin films as well as the change of valence of Mn ion.

The variation of the stable region of arsenic compounds in aqueous environment with temperature has been investigated by constructing the Pourbaix diagram of arsenic at different temperatures. The standard potential corresponding to the boundary between arsenic compounds with different charge valence was estimated to be decreased with temperature, which means the stability of arsenic compound with +5 charge valence increases. The distribution diagram of the most highly oxidized arsenic compound showed that arsenic acid is formed at higher pH and arsenate is generated at lower pH as temperature rises. The aquatic toxicity due to arsenic compounds was considered to be decreased with temperature in the neutral pH condition based on the $LD_T$ value defined in this study.

Recently, nonthermal bioplasma has been attracted by researchers due to their potentials to modulate cellular functions resulting in changes of biomolecular electron band structures as well as cell morphologies. We have investigated the secondary electron emission characteristics from the surface of the erythrocyte, i.e., red blood cell (RBC) with and without the nonthermal bioplasma treatment in morphological and biomolecular aspects. The morphologies have been controlled by osmotic pressure and biomolecular structures were changed by well known reactive oxygen species. Ion-induced secondary electron emission coefficient have been measured by using gamma-focused ion beam (${\gamma}$-FIB) system, based on the quantum mechanical Auger neutralization theory. Our result suggests that the nonthermal bioplasma treatment on biological cells could result in change of the secondary electron emission coefficient characterizing the biomolecular valence band electron energy structures caused by the cell morphologies as well as its surface charge distributions.
