Laboratory equipment will continue to be developed and created as long as experiments continue. Up until now, the designs have been focused on the functional role; successfully process the study purpose. However, nowadays, the requirements of providing emotional satisfaction of the design, has increased. Even so, the users are normally limited by specific groups and investments on these designs have been neglected due to small annual production by the small market. Through this study, we have conducted an emotional evaluation on Temperature and Humidity Chamber`s (TH Chamber) exterior shape. First of all, we extracted emotional words and placed them in categories that represent these emotions and conducted an emotional evaluation on four typical TH chamber models. They were selected based on its door lock type and control box type. The result showed that the ``fixed type`` of control box and the ``handle type`` of door lock were most favorable by the users, satisfying the five representative emotions; ``Attractiveness``, ``Classiness``, ``Comfortableness``, ``Pleasant`` and ``Satisfaction in Usability``. Particularly, all 4 emotional words in the ``Satisfaction in Usability`` category recorded over 3.65. This indicates that Satisfaction in Usability is relatively an important category when expressing laboratory equipment. The result of this research is expected to be used as a basic data to find a way of right approach in laboratory equipment design.

The goal of this study is to determine the social emotion model as an emotion sharing relationship and information sharing relationship based on the user`s relations at social networking services. 26 social emotions were extracted by verification of compliance among 92 different emotions collected from the literature survey. The survey on the 26 emotion words was verified to the similarity of social relation types to the Likert7-points scale. The principal component analysis of the survey data determined 12 representative social emotions in the emotion sharing relation and 13 representative social emotions in the information sharing relation. Multidimensional scaling developed the two-dimensional social emotion model of emotion sharing relation and of information sharing relation based on online communication environment, Meanwhile, insignificant factors in the suggest social emotion models were removed by the structural equation modeling analysis, statistically. The test result of validity analysis demonstrated the fitness of social emotion models at emotion sharing relationships (CFI: .887, TLI: .885, RMSEA: .094), social emotion model of information sharing relationships (CFI: .917, TLI: .900, RMSEA: 0.050). In conclusion, this study presents two different social emotion models based on two different relation types. The findings of this study will provide not only a reference of evaluating social emotions in designing social networking services but also a direction of improving social emotions.

In this study we investigated emotional characteristics of various whites which have slightly different nuances to suggest guidelines that help designers to select appropriate colors when designing white based products. The study involved three different procedures. In experiment 1, we selected 20 emotional words through a survey (N=30) among 60 words, which we picked from literature review that was thought to be appropriate to evaluate product colors. In experiment 2, we evaluated the emotional characteristics of 13 basic colors from the I.R.I Hue & Tone 120 system (N=30) using previously selected emotional words, to find relative emotional positions of white in comparison to other colors. Based on the ratings, factor analysis was conducted and consequently four factors were extracted: flamboyant, elegant, clear, and soft. Accordingly, the emotional characteristics of the 13 colors were profiled and compared with those of white. Finally, in experiment 3, we conducted an evaluation of emotional characteristics on 25 whites with different nuances facilitating the four factors obtained in experiment 2. The color stimuli used in experiments were measured in terms of CIE 1976 L*a*b*, and regression analysis was performed in order to predict the emotional characteristics through the L, a, and b values of a color, as long as that is perceived as a white. Throughout three empirical studies, we observed three overruling tendencies: First, there are four important factors when evaluating product color - flamboyant, elegance, clearness and softness; second, white is dominantly the most elegant in comparison to other colors; third, the emotional factors of the study were affected by some combinations of attributes of colors rather than by all three -hue, saturation and brightness. In addition, the equations derived from the regression analysis in experiment 3, it is expected that designers may predict the emotional distinction between nuances of white.

Two experiments were conducted to test effects of ethnicity and gender of face stimuli and lineup procedure on face recognition. In experiment 1, all stimuli were frontal male pictures of Southeast Asian and Northeast Asian. It was tested that whether accuracy of face recognition improve when ethnicity of participant and stimulus was identical (own-ethnicity advantage). In experiment 2, the ``own-gender advantage`` was tested using images of Northeast Asian`s frontal male and female faces. All participants were Northeast Asian. The results showed that the own-ethnicity advantage or the effect of line-up procedure was not found, but accuracy of face recognition was high when target face was Southeast Asian, Interestingly, the own-gender advantages was observed in only case of female participants, It was discussed that face recognition could be affected by attention.

This paper uses the sensibility engineering method to find the model of automobile most appealing to buyers in the 4th and 5th tier cities of China. Samples of class A & A0 cars were shown to 96 subjects in those cities to investigate their responses in relation to the concepts ``modern`` and ``smart``. The result shows that even though men tend to be more sensitive to automobile models in general than women are, both genders showed similar responses to specific models when they were asked to identify a model ``magnificent``, ``modern``, ``lively``, ``smart`` or ``cute``. This implies that despite the gender differences in terms of aesthetic sensitivity, both men and women share similar taste in relation to the appearance of cars. Apart from aesthetics, however, men tend to pay a greater attention to the details of design and material used for the cars, while women tend to pay attention to higher priced and better looking cars.
