LED lighting has an advantage of adjusting color temperature. This change of color temperature may derive change in behavioral and physiological responses of the visual perception for indoor environments. This research examined the changes of behavioral and physiological responses caused by the color temperature. The environment was configured that the indoor temperature was 20 degrees centigrade or less as the perceived uncomfortable environment in winter. Then, the comfortable sensation vote (CSV) and the results of 3-back working memory test were measured as behavioral responses. In addition, the Electrodermal Activity (EDA) and Electrocardiogram (ECG) were measured as the responses of autonomics nervous system (ANS) in the three conditions of color temperature (red: 3862K, white: 5052K, blue: 11,460K). As a result, behavioral responses were not significant by the condition of color temperature, but the tendency of occupants' physiological relaxation appeared in the blue color temperature condition compared with the white color temperature condition. Although the color temperature of LED lighting might be a small factor in terms of the characteristics of indoor environment, it suggests that the color temperature could have an impact on the physiological changes in the parasympathetic nervous system.

The purpose of this study is to research the level of emotional responses and corresponding behavioral responses of consumers who have experienced out-of-stock (OOS) shopping. Answers were gathered from 526 people in the 20-49 year age range, residing in a metropolitan area. SPSS 18.0 was used to perform factor analysis, reliability measures and regression analysis. The subordinate concept of emotional responses from consumers who experience an OOS event while at an on online shopping mall is the first subject of research for this study; this is tied in with three central factors; namely, anger/annoyance, anxiety and feeling regret. These can be further categorized into a positive emotional response and a negative emotional response. The experiment scrutinizes how emotional responses towards an OOS event experience affect behavioral responses. It then focuses on positive emotional responses as the second subject of this research: namely, how regret significantly affects the product substitution (S), and how anger/annoyance, anxiety and regret significantly influence a delayed purchase (D). Anger/annoyance, anxiety and regret significantly affect the incomplete store switch over (L1), and anger/annoyance and anxiety significantly influence the complete store switch over (L2).

Magnesium ion is known to selectively block the N-methyl-D-aspartate (NMDA)-induced responses and to have anticonvulsive action, neuroprotective effect and antinociceptive action in the behavioral test. In this study, we investigated the effect of $Mg^{2+}$ on the responses of dorsal horn neurons to cutaneous thermal stimulation and graded electrical stimulation of afferent nerves as well as to excitatory amino acids and also elucidated whether the actions of $Ca^{2+}$ and $Mg^{2+}$ are additive or antagonistic. $Mg^{2+}$ suppressed the thermal and C-fiber responses of wide dynamic range (WDR) cell without any effect on the A-fiber responses. When $Mg^{2+}$ was directly applied onto the spinal cord, its inhibitory effect was dependent on the concentration of $Mg^{2+}$ and duration of application. The NMDA- and kainate-induced responses of WDR cell were suppressed by $Mg^{2+}$, the NMDA-induced responses being inhibited more strongly. $Ca^{2+}$ also inhibited the NMDA-induced responses current-dependently. Both inhibitory actions of $Mg^{2+}$ and $Ca^{2+}$ were additive, while $Mg^{2+}$ suppressed the EGTA-induced augmentation of WDR cell responses to NMDA and C-fiber stimulation. Magnesium had dual effects on the spontaneous activities of WDR cell. These experimental findings suggest that $Mg^{2+}$ is implicated in the modulation of pain in the rat spinal cord by inhibiting the responses of WDR cell to noxious stimuli more strongly than innocuous stimuli.

Objective: This entire study has two parts. Study I aimed to develop a psychological assessment scale and the study II aimed to investigate the effects of LFN (low frequency noise) on the psychological responses in humans, using the scale developed in the study I. Background: LFN is known to have a negative impact on the functioning of humans. The negative impact of LFN can be categorized into two major areas of functioning of humans, physiological and psychological areas of functioning. The physiological impact can cause abnormalities in threshold, balancing and/or vestibular system, cardiovascular system and, hormone changes. Psychological functioning includes cognition, communication, mental health, and annoyance. Method: 182 college students participated in the study I in development of a psychological assessment scale and 42 paid volunteers participated in the study II to measure psychological responses. The LFN stimuli consisted of 12 different pure tones and 12 different 1 octave-band white noises and each stimulus had 4 different frequencies and 3 different sounds pressure levels. Results: We developed the psychological assessment scale consisting of 17 items with 3 dimensions of psychological responses (i.e., perceived physical, perceived physiological, and emotional responses). The main findings of LFN on the responses were as follows: 1. Perceived psychological responses showed a linear relation with SPL (sound pressure level), that is the higher the SPL is, the higher the negative psychological responses were. 2. Psychological responses showed quadric relations with SPL in general. 3. More negative responses at 31.5Hz LFN than those of 63 and 125Hz were reported, which is deemed to be caused by perceived vibration by 31.5Hz. 'Perceived vibration' at 31.5Hz than those of other frequencies of LFN is deemed to have amplified the negative psychological response. Consequently there found different effects of low frequency noise with different frequencies and intensity (SPL) on multiple psychological responses. Conclusion: Three dimensions of psychological responses drawn in regard to this study differed from others in the frequencies and SLP of LFN. Negative psychological responses are deemed to be differently affected by the frequency, SPL of the LFN and 'feel vibration' induced by the LFN. Application: The psychological scale from our study can be applied in quantitative psychological measurement of LFN at home or industrial environment. In addition, it can also help design systems to block LFN to provide optimal conditions if used the study outcome, .i.e., the relations between physical and psychological responses of LFN.

This study of nurse educator's attitudes which found aspects of professional nursing was carried out from September 10 to 30, 1977. Subjects were 205 respondents from a total population of 314 nurse educators from the level of instructors to professors in all the diploma (post high school 3 year), professional junior college (3 year level) and university (4 year) nursing schools in Korea. Specific objectives were to determine their attitudes about the 1. social position of nursing as a profession, 2. nurses attitudes towards their word, 3. factors influencing the development of nursing, 4. the future of nursing, 5. nursing educational problems, 6. their own educational position's intrinsic job satisfaction and 7. their salary and benefits. The instrument used was a questionnaire developed from consultations with nursing educators and sociologists, and based on earlier. worts by Burke (1976), Mason (1974) and Hong 1969. Data were analysis by computer using one-way analysis. Statistically significant findings included the following; 1. Responses were positive toward all seven aspects of professional nursing. 2. Compared to diploma nursing school staff whose responses were positive, professional and university school faculty response toward the social position of nursing were neutral. 3. Faculty with clinical experience of 10 to 19 years were most positive in their responses about nurses' attitudes towards their work. In all three types of schools, in comparison to professors, associate professors' responses were more positive about nurses' attitudes toward their work. Faculty with longer clinical experience expressed high agreement with statements about factors which influence the development of nursing. Without any differences between school, all faculty had positive attitudes towards the future of nursing, the younger the staff member, the more positive were the responses. 4. faculty in diploma schools and those with 10 to 19 years clinical experience expressed high agreement with statement about nursing educational problems, 6. their own educational position's intrinsic job satisfaction and 7. their salary and benefits.

The present study examined the effectiveness and communications functions of mothers' touch on the responses of their 6-month-old infants using the Still-Face (SF) situation. Participants were 67 infant-mother dyads from Seoul and Gyeonggi province. Positive and negative responses of infants were measured by SF interactions and by three different touch conditions. Touch types were measured by a coding scheme based on Suchung Kim and Keumjoo Kwak (2003; 2(04). Results showed that mothers' touch affected baby's responses by increasing positive responses and decreasing negative responses. The positive and negative responses of infants differed by the three different touch conditions, indicating that mothers use different touch types according to touch conditions; these variations in touch function as an important channel of communications.

This study examined whether preschool children's meta-socialization (conceptions of social situations) and their responses differed according to the children's gender. The participants were 78 preschool children living in Seoul, Korea. The results showed gender differences in the children's conceptions of social situations and in their responses to social situations. Firstly, a girl's conceptual judgments about social situations were more developed and dependent on the teacher's authority. Secondly, the boys showed direct and physical responses, while girls showed indirect, linguistic, and emotional responses in moral and social-conventional situations. In addition, girls made more frequent responses to 'Choice Assertion' in personal situations than boys.

This study investigates effect of uncertainty in natural vibration period on the seismic demand. It is shown that since this uncertainty affects the acceleration and displacement responses differently, two ratios, one relating peak acceleration responses and the other relating the peak displacement responses, are not equal and both must be employed in evaluating and defining the critical seismic demand. The evaluation of the ratios is carried out using more than 200 strong ground motion records. The results suggest that the uncertainty in the natural vibration period impacts significantly the statistics of the ratios relating the peak responses. By using the statistics of the ratios, a procedure and sets of empirical equations are developed for estimating the probability consistent seismic demand for both linear and nonlinear systems.

This study investigates the effects of information and predisposition on individual responses to hypothetical questions. By employing the empirical implications of theoretical models (EITM) framework, I confirm that information and predisposition have positive effects on individual substantive responses to the hypothetical questions about the independence-unification issue in Taiwan. Respondents with higher levels of information and predisposition are more likely to provide substantive responses. More importantly, information and predisposition exert a negative interaction effect on individual responses to hypothetical questions, which implies that when an individual counts more on information to respond to hypothetical questions, her predisposition plays a less important role in her responses and vice versa. Finally, this study suggests that hypothetical questions are effective to probe individual opinion on specific issues under hypothetical conditions.

1. The isolated strips of guinea-pig, fowl and reptiles (snake and tortoise) showed consistenly excitatory responses to $PGE_1\;and\;E_2$, which were dose-dependent. 2. Frog intestine revealed inhibitory responses to both $PGE_1\;and\;PGE_2$ except a small of $PGE_2$ (1-10 ng/ml) caused slight contraction. 3. The intestines of pieces showed inconsistent responses to $PGE_1\;and\;E_2$. In fresh-water fish(carp), $PGE_1$ produced relaxation under the dose of 50 ng/ml, and contraction by the large doses, but $PGE_2$ consistently caused contraction in dose-dependent manner. However, the strips of sea-water fish revealed the different responses to PGE compound: $PGE_1$ caused relaxation and $PGE_2$ conversly contraction even though in small degree. 4. These results that there are genera differences in the responses of the longitudinal strips of intestine to $PGE_1\;and\;PGE_2$ was assumed to be possibly correlated with evolutionally primitive function of gut.
