Effect of Gaze Direction of Human Faces on Cosmetic Paper Advertisement
Seungji Lee,Sung-Phil Kim 한국HCI학회 2017 한국HCI학회 학술대회 Vol.2017 No.2
In cosmetic paper advertisement, models are important components for marketers to imprint the products to customers (e.g. Kim’s essence). One possible method to attract attention from customers is gaze direction of a model. This study aimed to identify how a model’s gaze direction affects a customer’s gaze pattern and how it relates to purchase intention. The gender effect was also investigated. The result showed a near-marginally significant observation that when a model gazed toward us, fixation duration on the model became longer and the number of visit increased. In addition, customers attracted by the model at the first time were likely to buy the product. The different gaze patterns between male and female were observed. The study indicates that the gaze direction of a model can affect fixation duration on model, which is correlated with the first fixation on model and finally leading to purchase behavior.

<P>In this paper, we fabricated In<SUB>0.53</SUB>Ga<SUB>0.47</SUB>As-on insulator (OI) MOSFETs on Si substrates with different doping types to mimic ground plane doping using direct wafer bonding and epitaxial lift-off (ELO) techniques. We investigated the impact of doping types on the ground plane and the backgate biasing, which are important and preferable components in monolithic 3-D (M3D) integration, on the electrical properties of MOSFETs, such as the threshold voltage ( <TEX>${V} _{T}$</TEX>) and the effective mobility ( <TEX>$\mu _{\textsf {eff}}$</TEX>). It was found that <TEX>${V} _{T}$</TEX> and <TEX>$\mu _{\textsf {eff}}$</TEX> were significantly modulated by the backsubstrate doping and the backbiasing. These observations were explained by the change of carrier distributions, which were confirmed by technology computer-aided design simulation. Furthermore, we investigated the reusability of InP donor substrates for sequential epitaxial growth after ELO process toward a cost-effective M3D integration with the In<SUB>0.53</SUB>Ga<SUB>0.47</SUB>As channel.</P>

A case of cutaneous myiasis associated with basal cell carcinoma on the scalp

Cutaneous myiasis is the infestation of skin by larvae of different fly species within the arthropod order Diptera. There are two main clinical presentations of cutaneous myiasis: wound and furuncular. The treatment of cutaneous myiasis involves usage of anti-larval measures promoting larval asphyxia and inducing them to exit from the wound, followed by mechanical removal of the larvae.Larvae rupture must be avoided. In larger lesions, or when there is adjacent cellulitis, removal of devitalized tissue is recommended. A broad antibiotics cover is recommended to prevent secondary infections. A 78-year-old Korean woman presented with a ulcerative and hemorrhagic scalp mass which in some parts is covered by larvae. The larvae were mechanically removed, and the biopsy of the ulcerative scalp mass confirmed the diagnosis of adenoid type basal cell carcinoma. The patient was referred to plastic surgeon for resection and graft of the basal cell carcinoma on the scalp. Cutaneous myiasis has rarely been reported in skin tumors such as basal cell carcinoma. So, we report a case of cutaneous myiasis associated with basal cell carcinoma on the scalp.
Robust Adaptive Control of A HexaSlide Type Parallel Manipulator
Kim, Jong-Phil,Kim, Sung-Gaun,Ryu, Jeha Institute of Control 2001 Transaction on control, automation and systems eng Vol.3 No.4
Jeha Ryu Department of Mechatronics, Kwangju Institute of Science and Technology This paper presents an application of a robust adaptive control strategy to HexaSlide type six degrees-of-freedom parallel manipulators. The HexaSlide type parallel manipulators are characterized as an architecture with constant link lengths that are attached to moving sliders on the ground and to a mobile platform. The proposed control law is developed based on a simplified second order system dynamic equation in joint space with uncertain mass, damper, spring, and Coulomb friction terms. These uncertain parameters are updated by an adaptation law that is derived by Lyapunov stability theorem. A robust adaptive control law by using the boundary layer is designed for the purpose of compensating for the neglected dynamic effects of the mobile platform and the six moving links that are modeled as a disturbance term. Experimental results show good and fast tracking performance.
Zinc Chloride Toxicity on Free Proline and Organic Acids in Germinating Rice Seed
Kim, Sang-Kuk,Chung, Sang-Hwan,Lee, Sang-Chul,Lee, Seong-Phil The Korean Society of Crop Science 1999 Korean journal of crop science Vol.44 No.2
The study was conducted to find the critical concentrations of zinc toxicity and to determine the changes of the contents of free proline and organic acids with treatment of different zinc chloride concentrations during rice germination and seedlings grown for seven days. The concentration of zinc chloride, 140 ppm, inhibited root elongation as much as 46 times compared with the control, and the germination rate was also decreased in all treatments of zinc chloride, showing that the germination rate decreased more with increasing concentrations of zinc chloride. Its rate was only 13% with treatment of 140 ppm zinc chloride. The content of free proline with treatment of zinc chloride, 140 ppm, was highest about 4,873 $\mu$M at 3 days compared with the control. Malic acid concentration with treatment of zinc chloride, 140 ppm, increased to approximately 4 times compared to the control. Citric and succinic acid content were also slightly increased in all treatments of zinc chloride.

25 bacterial strains that secrete mucous materials were isolated from sediment obtained from King George Island, Antarctica. Seven of these strains proved capable of producing cryoprotective exopolysaccharides. The strain KOPRI 21653 was selected for the further study. KOPRI 21653 was identified as Pseudoalteromonas arctica as the result of 16S rRNA analysis. The exopolysaccharide, P-21653, was purified by Cetylpyridinium chloride (CPC) and protease treatment from the KOPRI 21653 culture. The sugar components of P-21653 determined to be galactose and glucose, at a ratio of 1:1.5, by GC-MS analysis. The cryoprotective effect of P-21653 was determined by a red blood cell (RBC) LDH assay. In the presence of 0.5% (w/v) P-21653, the Damaged cell ratio of RBC was 20.83±2.83%, after three repeated freeze-thaw cycles. The damaged cell ratio of RBC increased to 26.1%, in five repeated cycle conditions in same concentration of P-21653. However, the damaged cell ratios of RBC were increased (20.83±2.83 - 42.11±7.27 %) in the presence of 0.5 - 0.2% (w/v) P-21653. In addition, at lower concentrations of P-21653 (0.2 - 0.5%), the damaged cell ratios of RBC were more less than generally employed as a RBC cryoprotectant (glycerol), which was utilized at the recommended concentrations (40%). The biochemical characteristics of exo-polysaccharide P-21653 reflect that this compound may be developed as a useful cryo-protectant for use in medical applications.
