FACIAL EMOTION EXPRESSION IN ANIMATION CHARACTERS
Hyeyoung Ko,Hyemin Ko,Jeongju Kim,Jaeho Kim 한국멀티미디어학회 2007 한국멀티미디어학회 국제학술대회 Vol.2007 No.-
Facial expression is the most important to communicate the emotions among many non-verbal communication means. Animation characters have shown their inherent personality and emotions mainly through the facial motions. The authors have found that 43 expressions are good enough for showing various emotions. This experiment was carried out two steps. Firstly, four distinct personal characters whose facial expressions are covering the most of animation facial expressions are selected. The personalities of the four characters are studied. Secondly, the facial expressions of the characters are extracted from animation movies. And we could find the distinct 43 expressions by using a generic model character. It is found that, if we have 25 eye and 18 lip expressions, all facial expressions can be covered. This result suggests us in building minimal data set for the database of auto character facial expression.

<P><B>Abstract</B></P> <P>We report on the in-situ chemical growth of unique core-shell quantum dots (QDs) with single layer graphene on the surface of CuO QDs and their structural, optical and electrical properties. The CuO/graphene QDs were synthesized through a simple and hydrothermal technique. In order to enhance performance electrochemical energy storages, we have developed core (active material)/shell (conductive material) type CuO/graphene QDs as electrode materials using the combined electrolytes (KOH + LiCl). As a result, the performance of electrochemical energy storages exhibits specific capacitance of 154 F g<SUP>−1</SUP> at current density of 1 A g<SUP>−1</SUP> and cycling stability with 84% capacitance retention after 3,000 cycles.</P> <P><B>Highlights</B></P> <P> <UL> <LI> The CuO/G QDs were synthesized through a simple and hydrothermal technique. </LI> <LI> The capacitance has enhanced using the combined hybrid electrolyte (KOH + LiCl). </LI> <LI> Specific capacitance exhibits 154 F g<SUP>−1</SUP> at current density of 1 A g<SUP>−1</SUP>. </LI> <LI> Cycling stability show 84% capacitance retention after 3,000 cycles. </LI> </UL> </P>

Background: The incidence of facial palsy has been increasing. Many patients consult both Korean and Western physicians; however, no critical pathway (CP) for facial palsy has been established based on integrated medicine including Korean medicine, Western medicine, and complementary and alternative medicine. Thus, we developed and implemented an integrated CP for patients with acute facial palsy and investigated the satisfaction with CP. Methods: Overall, 20 patients who received treatment following the CP and 20 medical staff members involved in their care responded to a questionnaire survey. The questionnaire was developed based on a review of previous studies and focused on the satisfaction with the CP. Results: Patients’ satisfaction score with the integrated CP was ≥ 4.4 for all items using a 5-point Likert-type scale. Smooth and cooperative treatment procedures, time-saving practices, and a clear explanation of the integrated treatment plan were satisfactory factors. Additionally, they preferred incorporating specialized facial massage and receiving education on self-exercise or massage techniques as complementary therapies. The medical staff members expressed a high level of satisfaction with the CP; however, the work division and treatment guidelines must be improved. Conclusion: An integrated CP program for acute facial palsy was implemented, and the satisfaction levels of patients and medical staff members were assessed. The results revealed high levels of satisfaction, and several improvements identified will be incorporated into clinical practice going forward.

<P><B>Abstract</B></P> <P>This work reports on the in-situ chemical synthesis and their properties of the core (active material)/shell (conductive material) type Co<SUB>3</SUB>O<SUB>4</SUB>/graphene quantum dots (QDs). The stable oxygen bridge bonds between the Co<SUB>3</SUB>O<SUB>4</SUB> core and the oxygen-related functional groups on the graphene shells facilitate the efficient charge/discharge performance. The efficient electron transfer process between the Co<SUB>3</SUB>O<SUB>4</SUB> core and the graphene shell lead to an improvement in the electrochemical activity. The specific capacitances of Co<SUB>3</SUB>O<SUB>4</SUB>/graphene QDs electrode, without conductive additives, exhibit high values of 2435 F g<SUP>−1</SUP> at current densities of 1 A g<SUP>−1</SUP>. It breaks through 126% of the initial capacitance after 500 cycles and show above 112% even after 4500 cycles. The excellent performance of the Co<SUB>3</SUB>O<SUB>4</SUB>/G QDs electrode is attributed to the significant improvement of the electrochemical activity, without conductive additives, due to the presence of metal oxide QD covered by graphene shells which leads to the good electrical properties.</P>
