  • When consumer evaluates a product, every aspec of the product affects the evaluation. Human uses at least five sensory organs for the evaluation. Multi-sensory or multi-modal design tries to add auditory and olfactory factors to the traditional visual-centered design. For the multi-modal design, it is essential to understand relationships between combined sensory stimuli and human sensibility. Information between simple sensory stimulus and human sensibility is pre-requisite to combine multi-modal stimuli. This study investigated human sensibility against 8 colors and 30 sounds, presented independently. The combined stimuli of color and sound were made based on the sensibility generated by each stimulus. Human sensibility generated by the combined stimuli of color and sound were made based on the sensibility generated by each stimulus. Human sensibility generated by the combined stimuli was investigated with 20 female subjects. For combined stimuli that generated the same kind of sensibility respectively, generated sensibility was same but strength was diminished. For combined stimuli that generated the different sensibilities respectively, subjects showed neutral sensibility or no special sensibilities. Sensibilities to the same stimuli also showed difference depending on personal background of the subjects.

  • This study was designed to investigate the effect of a combined stimulus which was composed of chiropractic massage and thermotherapy on the relief of mental and physical stress. Fifteen healthy male subjects were treated with three type of stimuli; control (without any stimulus), a single stimulus (only chiropractic) and a combined stimulus. To evaluate the effects of stimuli, visual analogue scale (VAS), trunk extension, electromyogram (EMG) on erector spinae muscle and electrocardiogram (ECG) were measured and analyzed before and after stimuli. In the control group, there were no significant changes in EMG root mean square (RMS) value and low Frequency/high Frequency (LF/HF) ratio (p > 0.05, p > 0.05). However, both stimulus groups showed significant increases in trunk extension and EMG RMS values (p < 0.05, p < 0.05), but significant decreases in LF/HF ratios (p < 0.05). Particularly the decrement rate in LF/HF ratio was significantly higher in the combined stimulus group than that in the single stimulus group (p < 0.05). Also, a significantly lower VAS was recorded after combined stimulus. Our findings indicate that the combined stimulus might not only improve flexibility and strength of muscle, but also active parasympathetic nerve activity. The combined stimulus may thus contribute to relieve the stress and to enhance the muscle function.

  • Caenorhabditis elegans (C.elegans) has various interesting behavioral properties, such as chemotaxis, thermotaxis, and electrotaxis. However, most previous research were only focused on single-stimulus for studying its behavioral properties. In this paper, we propose a simple and effective device for analyzing the behavior of C.elegans with combined stimuli, electric field and temperature. We compared and analyzed wild type worms (N2) and four mutant worms (tax-4, ttx-7, unc-54, unc-6). We analyzed the reaction of worms to certain stimulus and identified that this device is effective to apply a combined stimulus.

  • Photonic band gap (PBG) materials have been of great interest due to their potential applications in science and technology. Their applications can be further extended when PBG becomes tunable against various chemical and electrical stimuli. In recent, it was found that tunable photonic band gap materials can be achieved by incorporating stimuli-responsive smart gels into PBG materials. For example, the characteristic volume phase transition of gels in response to the various external stimuli including temperature, pH, ionic strength, solvent compositions and electric field were recently combined with the unique optical properties of photonic crystals to form unprecedented highly responsive optical components. Since these responsive photonic crystals are capable of reversibly converting chemical or electrical energy into characteristic optical signals, they have been considered as a good platform for label-free chemical or biological detection, actuators or optical switches as well as a model system for investigating gel swelling behavior. Herein, we report block copolymer photonic gels self-assembled from polystyrene-b-poly (2-vinyl pyridine) (PS-b-P2VP) block copolymers. In this talk, we are going to demonstrate that selective swelling of lamellar structure can be effectively utilized for fabricating PBG materials with extremely large tunability. Optical properties and their applications will be discussed.

  • Shangwan(CV13), Zhongwan(CV12), Xiawan(CV10), Hefu(L14) and Taichong(LR3) which belong to Conception Vessel and stomach meridian are acupuncture points frequently used for healing gastrointestinal desease in oriental medicine. The present study was conducted to see the effects produced by combined acupuncture(A), electro-acupuncture(EA) and moxibustion using five acupoints which belongs to different meridians on serum gastrin level in rats. Electro-acupuncture (2 Hz, intensity; 10 times muscle twitch threshold) was applied for 30 minutes to Hefu(LI4), Taichong(LR3) under halothane anesthesia. Moxibustion ($1.6{\pm}0.3\;mg$, 5 times of a day) was applied during 3 days to CV10, CV12, CV13 under halothane anesthesia. Combined stimuli of acupuncture at Hefu(LI4), Taichong(LR3) and moxibustion at CV13, CV12 increased serum gastrin level significantly eventough combined simulus of moxibustion on CV 10 was not shown any change. And combined stimul of EA and moxibustion at experimental all groups were not shown any effects. These data suggest that effects of acupuncture and moxibustion are depentent with used acupoints and combination stimuli method.

  • This study is on the image evaluation of the hair up-style and the wedding dress styles of prospective brides. Based on some prior theoretical studies, and information obtained from wedding magazines and interviews conducted at the beauty business places, four kinds of the hair up-style were selected, namely, top-point, golden-point, back-point, and nape point. Three styles of necklines were selected: boat necklines, V-necklines, and off-shoulder necklines. The surveyor herself did the hair styling for models, and dressed up the models, to produce the stimuli. And the stimuli were presented to percipients along with questionnaires for measuring the image evaluations. Prepared were total 12 different kinds of stimuli, in which four hair up-styles and three dress styles were combined into 12 combinations ($3^*4$), and, with respect to these 12 stimuli, 26 itemized questions were included in the questionnaire. From the factor analysis on the image evaluation of the hair up- style and wedding dresses, five factors were derived as fallowing: attractiveness, boldness, purity, cuteness, feminity. This study revealed that wedding dress styles are more sensitive to the contemporary trend, compared to the hair styles; and the selection in the wedding style is quite influenced by the dress style, but not by the hair up-style. Also, prospective brides evaluated the hair up-styles and the wedding dress styles separately without recognizing their mutual relationship, and thus did not recognize the two as the mutually coordinated relationship, but rather recognize the two as two separate elements.

  • A novel gene, designated mgt-6, containing four splicing variants, was isolated from a gene trap clone library of C3H/10T1/2 cells transfected with retroviral promoterless gene-trap vector, ROSAFARY. The transcript variants were differentially expressed in murine tissues and cell lines and differentially responded to diverse stimuli including TGF-${\beta}1$ and mitogen-activated protein kinase (MAPK) inhibitors. The mgt-6 gene encoded a protein of 37 or 11 amino acid residuals with cytoplasmic distribution. However, when C3H/10T1/2 cells were treated with 5-azacytidine, the protein translocated into cell nucleus as indicated by fused LacZ or C-terminally tagged EGFP. Our preliminary results suggest that further study on the role of mgt-6 gene in cell transformation and differentiation may be of significance.

  • This study looks at common features between the two media to explore the deepening relationship within music and images in movies and finds at how they are combined each other and the resulting effects. Beyond the limitations of conventional viewpoints of music as video-dependent media, The is analyzed to focus on the deepening relationship between the two media. In the movie, music and video were combined by sharing the same attributes of 'repeating structure', which increases the transmission power to the film's subject and story, maximizes visual and auditory stimuli, and forms a sense of immersion. That is, video and music combined in equal positions have great influence to each other, thus representing for a positive consideration of the potential for establishing interdependent relationships.

  • In this paper, we propose the new emotion model and the robot behavior decision model based on proposed emotion model. As like in human, emotions are hierarchicalized in four levels (momentary emotions, mood, attitude, and personality) and are determined from the robot behavior and human responses. They are combined with motivation (which is determined from the external stimuli) to determine the robot behavior.

  • The present study investigates the perception of Korean phonation types by native speakers of Aymara. Perception tests were conducted on two sets of Korean speech materials to determine correspondence between Korean and Aymara 3-way contrasts and to find out which of the consonantal and vocalic part of the syllable is more influential in the perception of Korean phonation types. A set of manipulated stimuli, as well as a set of 12 spontaneous words, were prepared for the tests. The first syllable of the 12 Korean bisyllabic words of 3 series of phonation types(Lenis, Aspirated, and Fortis) in 4 places of articulation were split into consonantal and vocalic parts. And then the two parts were combined to form 9 tokens of CV sequences respectively for each place of articulation. Native speakers of Aymara were forced to match Korean stimuli with one of the 15 Aymara words which represent 3 series of consonant types(plain, aspirated, and ejective) in 5 places of articulation(bilabial, alveolar, palatal, velar, and uvular). Results showed that the consonantal part is more influential than the vocalic part to the Aymara subjects' perception of Korean phonation types when the consonantal part is Aspirated in its phonation type, but the vocalic part is more influential than the consonantal part when the consonantal part is Lenis or Fortis in its phonation type. Response analysis showed that Aymara subjects tend to match Korean stops to Aymara ones in such a way that Lenis corresponds to aspirated, Aspirated to aspirated, and Fortis to plain.
