Purpose: To investigate the effect of smoking cessation expectation and on the stress for subjects in smoking cessation clinic and effect of self-efficacy in the relationship between expectancy and stress, with the aim of establishing an effective management smoking cessation strategy. Methods: Current smokers (n=161) >30-years-of-age who were residents of G city completed a questionnaire. Results: Concerning the effect of self-efficacy and the expectancy on stress, they were significantly effective in first, second and third stage, and appeared 8.3% in first stage, 13.8% in third stage, showing self-efficacy has a controlling effect on stress. Conclusion: Smoking cessation expectancy and self-efficacy significantly influence stress, and must be taken into account in development of smoking-cessation strategies and programs.

Why do some countries walk on the right and others on the left? People have a dominant hand which leads to a natural tendency to favor one side of the road or another depending on the means of transportation being used. The primary objective of this study was to investigate the stereotype of Korean regarding preferred walking direction in encountering various facilities and provide the appropriate information to traffic policy makers. Six hundred Korean male and female subjects aging from 12 to 83 were selected to investigate the various statistics about their preferred walking direction and their employment characteristics on walking diverse facilities. The walking directions of eleven different facilities were asked along with other relative subjects' characteristics(e.g., age, gender, hand and foot dominance) to determine the relationship among these obtained data. The descriptive statistics showed that 73.7% and 26.3% were preferred walking right and left direction respectively. Moreover, various statistical analysis revealed that general tendency of walking direction was varied by hand and foot dominances. There were strong tendency that right-handed people prefer walking right side of the road and vise versa, hence this should be considered in setting up traffic policies. As a concluding remark, it is better to design traffic policies and regulations in the way that peoples' preference and expectation.

The remote sensing technique using SAR data have many advantages when applied to the disaster site due to its wide coverage and all-weather acquisition availability. Although a single-pol (polarimetric) SAR image cannot represent the land surface better than a quad-pol SAR image can, single-pol SAR data are worth using for disaster-induced change detection. In this paper, an automatic change detection method based on a mixture of GGDs (generalized Gaussian distribution) is proposed, and usability of the textural features and intensity is evaluated by using the proposed method. Three ALOS/PALSAR images were used in the experiments, and the study site was Norita City, which was affected by the 2011 Tohoku earthquake. The experiment results showed that the proposed automatic change detection method is practical for disaster sites where the large areas change. The intensity information is useful for detecting disaster-induced changes with a 68.3% g-mean, but the texture information is not. The autocorrelation and correlation show the interesting implication that they tend not to extract agricultural areas in the change detection map. Therefore, the final tsunami-induced change map is produced by the combination of three maps: one is derived from the intensity information and used as an initial map, and the others are derived from the textural information and used as auxiliary data.

Reactive oxygen species are capable of damaging biomolecules such as lipids, proteins, and DNA, which can not only lead to various diseases, but also oxidative damage resulting aging. In our previous study, Cercis chinensis (Leguminosae) showed a potent antioxidant activity. Nineteen compounds were isolated through antioxidant activity-guided fractionation. The C. chinensis extract and some of the constituents exhibited a potent antioxidant activity on the free radicals and lipid peroxidation and a notable protective effect on the t-BuOOH induced oxidative damage. In vivo test of skin damage induced by UVB irradiation, the extract of C. chinensis and a constituent, piceatannol, exhibited a significant protective effect. The life-span of the HEK-N/F cells were extended by 1.21-2.12 fold as a result of the continuous administration of 3 $\mu\textrm{g}$/ml of the C. chinensis extract and the active constituents compared to that of the control. These observations were attributed to the inhibitory effect of the C. chinensis extract and its constituents on the age-dependent shortening of the telomere. Thus, C. chinensis was demonstrated to protect the skin cells against oxidative stress and inhibit thereby the cellular aging, followed by expectation as antiaging cosmetic ingredient.

This study aims to investigate the change of functions of duibuqi and analysis other fuctions of duibuqi apart from apology from pragmatics and conversation analysis perspectives. Duibuqi consists of dui(face) and buqi(be not capable of performing), and means 'be not capable of facing'. After that, it is assumed to have changed to 'ashamed' and finally 'sorry'. In terms of functions, duibuqi is generally regarded as meaning 'sorry' typically, so mei guanxi is considered to consist adjacency pair with it, but in this investigation, mei guanxi is very little adjacent to duibuqi contrary to expectation(n=2/28, per.=7.1/100). About half of duibuqi(n=15/28, per.=53.6/100) functions in apology action sequence, and in the sequence, duibuqi functions much more for take the lead in apology(n=11/15) but not for a reaction against scolding(n=4/15). And the other half of duibuqi(n=13/28, per.=46.4/100) functions for softening the impact of reject or direct action, or for switching situations, e.g. from favorable situation to unfavorable situation, or for expressing speaker's emotion to the other's repair etc. Consequently, duibuqi has being changed its meanings and its functions is being changed accordingly.

Purpose: The purpose of this study was to explore nurses' experience of the role adaptation process and barriers in long-term care (LTC) facilities including nursing homes, daycare centers, and home visit nursing centers. Methods: After in-depth interviews with 13 nurses who were working at the LTC facilities in G province, the data were analyzed using Colaizzi's phenomenological methodology. Results: 17 themes with 6 theme clusters, and 2 categories emerged: nursing role adaptation process in the LTC (role expectation and readiness, role perception and performance, limits of role performance), and barriers to nursing role adaptation in the LTC facility (organizational, situational, and institutional-environmental barriers). Conclusion: The results showed that it is critical to establish the nurses' role in caring for the health of the elderly and maintaining the quality of care in the LTC facilities. In response to the growing demand for quality care in the LTC facilities, more institutional and environmental changes are needed to address the current barriers that prevent nurses from performing their appropriate roles.

This study investigates how the phonological and phonetic information of vowels influences prosodic prominence among linguistically untrained listeners using public speech in American English. We first examined the speech material's phonetic realization of vowels (i.e., maximum F0, F0 range, phone rate [as a measure of duration considering the speech rate of the utterance], and mean intensity). Results showed that the high vowels /i/ and /u/ likely had the highest max F0, while the low vowels /æ/ and /ɑ/ tended to have the highest mean intensity. Both high and low vowels had similarly high phone rates. Next, we examined the effects of the vowels' phonological and phonetic information on listeners' perceptions of prosodic prominence. The results showed that vowels significantly affected the likelihood of perceived prominence independent of acoustic cues. The high and low vowels affected probability of perceived prominence less than the mid vowels /ɛ/ and /ʌ/, although the former two were more likely to be phonetically enhanced in the speech than the latter. Overall, these results suggest that perceptions of prosodic prominence in English are not directly influenced by signal-driven factors (i.e., vowels' acoustic information) but are mediated by expectation-driven factors (e.g., vowels' phonological information).

The cationic polymerization of energetic substituted oxetanes which have pendant energetic group such as azido and nitrato are investigated theoretically, using semiempirical HF/3-21G, MINDO/3, MNDO and AM1 method. The stereo- and electronic structure of binary molecular complex composed of energetic substituted oxetane and boron trifluoride can be explain by molecular orbital theory. The reactivity of propagation in the copolymerization of oxetanes can be presented by the positive charge on carbon(C2) atom of oxetane and energy level of the lowest unoccupied molecular orbital(LUMO) of propagating species of oxetanes. The reactivity ratios for copolymerization of oxetanes are a random copolymer-zation which is agree with MO calculated and experimental results. The relative equlibrium concentration of cyclic oxonium and open carbenium ions is found to be a major determinant of mechanism, owing to the rapid equilibrium of these cation forms and the expectation based on calculation that in the prepolymer propagation step, SN1 mechanism will be at least as fast as that for SN2 mechanism.

Let C[0, t] denote the space of real-valued continuous functions on [0, t] and define a random vector $Z_n:C[0,t]{\rightarrow}\mathbb{R}^n$ by $Z_n(x)=(\int_{0}^{t_1}h(s)dx(s),{\ldots},\int_{0}^{t_n}h(s)dx(s))$, where 0 < $t_1$ < ${\cdots}$ < $ t_n=t$ is a partition of [0, t] and $h{\in}L_2[0,t]$ with $h{\neq}0$ a.e. Using a simple formula for a conditional expectation on C[0, t] with $Z_n$, we evaluate a generalized analytic conditional Wiener integral of the function $G_r(x)=F(x){\Psi}(\int_{0}^{t}v_1(s)dx(s),{\ldots},\int_{0}^{t}v_r(s)dx(s))$ for F in a Banach algebra and for ${\Psi}=f+{\phi}$ which need not be bounded or continuous, where $f{\in}L_p(\mathbb{R}^r)(1{\leq}p{\leq}{\infty})$, {$v_1,{\ldots},v_r$} is an orthonormal subset of $L_2[0,t]$ and ${\phi}$ is the Fourier transform of a measure of bounded variation over $\mathbb{R}^r$. Finally we establish various change of scale transformations for the generalized analytic conditional Wiener integrals of $G_r$ with the conditioning function $Z_n$.

I made the three main estimated head about the facility of mechanical pencil which we always use in normal days. The head are these, the first is apparent usability by experiment, the second is the feeling when grasping, the third is the feeling when writing. After making the head, 1 selected the head which give the effect to the facility and make sure the interaction between heads by the method of actual test with 36 samples. After this test, 1 can find that there is no high interaction between the facility and the intuitively feeling by experiment. It's because the expectation which was made by experiment for the facility is higher than the real. but there is high interaction between the feeling of wearing and the feeling of writing. The mechanical pencil which has good facility is that the total length is long(169mm), the thickness is big($\Phi$8.5mm), the weight is little bit heavy(21.4g), the intersection is not circle, the surface where is hold by fingers has across grooves, and the body is glossy.
