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>

( Phil Hyun Chung ),( Suk Kang ),( Jong Pil Kim ),( Young Sung Kim ),( Ho Min Lee ),( In Hwa Back ),( Kyeong Soo Eom ) 대한고관절학회 2016 Hip and Pelvis Vol.28 No.2
Purpose: Occult intertrochanteric fractures are misdiagnosed as isolated greater trochanteric fractures in some cases. We investigated the utility of three-dimensional computed tomography (3D-CT) and magnetic resonance imaging (MRI) in the diagnosis and outcome management of occult intertrochanteric fractures. Materials and Methods: This study involved 23 cases of greater trochanteric fractures as diagnosed using plain radiographs from January 2004 to July 2013. Until January 2008, 9 cases were examined with 3D-CT only, while 14 cases were screened with both 3D-CT and MRI scans. We analyzed diagnostic accuracy and treatment results following 3D-CT and MRI scanning. Results: Nine cases that underwent 3D-CT only were diagnosed with isolated greater trochanteric fractures without occult intertrochanteric fractures. Of these, a patient with displacement received surgical treatment. Of the 14 patients screened using both CT and MRI, 13 were diagnosed with occult intertrochanteric fractures. Of these, 11 were treated with surgical intervention and 2 with conservative management. Conclusion: Three-dimensional CT has very low diagnostic accuracy in diagnosing occult intertrochanteric fractures. For this reason, MRI is recommended to confirm a suspected occult intertrochanteric fracture and to determine the most appropriate mode of treatment.

Background: Human breast milk is essential and provides irreplaceable nutrients for early humans. However, breastfeeding is not easy for various reasons in medical institution environments. Therefore, in order to improve the breastfeeding environment, we investigated the difficult reality of breastfeeding through questionnaire responses from medical institution workers. Methods: A survey was conducted among 179 medical institution workers with experience in childbirth within the last five years. The survey results of 175 people were analyzed, with incoherent answers excluded. Results: Of the 175 people surveyed, a total of 108 people (61.7%) worked during the day, and 33 people (18.9%) worked in three shifts. Among 133 mothers who stayed with their babies in the same nursing room, 111 (93.3%) kept breastfeeding for more than a month, but among those who stayed apart, only 10 (71.4%) continued breastfeeding for more than a month (P = 0.024). Ninety-five (88.0%) of daytime workers, 32 (94.1%) two-shift workers, and 33 (100%) three-shift workers continued breastfeeding for more than a month (P = 0.026). Workers in general hospitals tended to breastfeed for significantly longer than those that worked in tertiary hospitals (P = 0.003). A difference was also noted between occupation categories (P = 0.019), but a more significant difference was found in the comparison between nurses and doctors (P = 0.012). Longer breastfeeding periods were noted when mothers worked three shifts (P = 0.037). Depending on the period planned for breastfeeding prior to childbirth, the actual breastfeeding maintenance period after birth showed a significant difference (P = 0.002). Of 112 mothers who responded to the question regarding difficulties in breastfeeding after returning to work, 87 (77.7%) mentioned a lack of time caused by being busy at work, 82 (73.2%) mentioned the need for places and appropriate circumstances. Conclusion: In medical institutions, it is recommended that environmental improvements in medical institutions, the implementation of supporting policies, and the provision of specialized education on breastfeeding are necessary to promote breastfeeding.
A case of cutaneous myiasis associated with basal cell carcinoma on the scalp
( Sung Eun Song ),( Young Uk Kim ),( Seung Woo Lee ),( Kea Jeung Kim ),( Joon Hong Min ),( Eun Phil Heo ) 대한피부과학회 2015 대한피부과학회 학술발표대회집 Vol.67 No.1
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.

Soil quality has been regarded as an important factor for maintaining sustainability of ecosystem. Main purpose of this research was i) to select minimum factor for predicting biomass, and ii) to calculate soil quality index for biomass according to soil chemical properties. Result showed that soil pH, electrical conductivity (EC), soil organic matter (SOM), cation exchange capacity (CEC), and available phosphorus are minimum data set for calculating biomass production in soil. Selected representative soil chemical properties were evaluated for soil quality index and rated from 1 to 5 (1 is the best for biomass production). Percentage of each grade in terms of biomass production in national wide was 14.52, 35.23, 33.03, 6.47, 10.75% respectively. Although, only soil chemical properties were evaluated for calculating optimum soil quality, result of this research can be useful to understand basic protocol of soil quality assessment in national wide.
