Al-doped ZnO 투명 전도성 박막(TCO)의 전기적 광학적 특성
홍윤정,이규만,김인우,Hong, Youn-Jeong,Lee, Kyu-Mann,Kim, In-Woo 한국반도체디스플레이기술학회 2007 반도체디스플레이기술학회지 Vol.6 No.3
ITO(Indium Tin Oxide) is the most attractive TCO(Transparent Conducting Oxide) materials for LCD, PDP, OLEDs and solar cell, because of their high optical transparency and electrical conductivity. However due to the shortage of indium resource, hard processing at low temperature, and decrease of optical property during hydrogen plasma treatment, their applications to the display industries are limited. Thus, recently the Al-doped ZnO(AZO) has been studied to substitute ITO. In this study, we have investigated the effect of different substrate temperature(RT, $150^{\circ}C$, $225^{\circ}C$, $300^{\circ}C$) and working pressure(10 mTorr, 20 mTorr, 30 mTorr, 80 mTorr) on the characteristics of AZO(2 wt.% Al, 98 wt.% ZnO) films deposited by RF-magnetron sputtering. We have obtained AZO thin films deposited at low temperature and all the deposited AZO thin films are grown as colunmar. The average transmittance in the visible wavelength region is over 80% for all the films and transmittance improved with increasing substrate temperature. Electrical properties of the AZO films improved with increasing substrate temperature.

Objectives : A common cold is a viral disease. There exists only allopathy for it depending on symptoms because of no cure. Korean medicine has taken a serious view of common cold patients with digestive problems as well as patients of the common cold. Accordingly, this study is aimed at finding out the traits of patients with digestive problems among common cold patients. Methods : A survey was conducted with 62 cold patients who got medical treatment in Korean medicine clinics located in small cities and towns including metropolitan cities. The SPSS for Windows( 19.0 Version) was used for statistical analysis. Results : Depending on which clinic common cold patients decided to go to, there was a significant difference in the number of sick days. The group of patients who decided to go straight to oriental medicine clinics had fewer sick days. Only 9.7% of the group of patients who got treatment in Koean medicine clinics had more than 6 sick days. The group of common cold patients with digestive problems had more sick days than the group with no digestive problems, which showed that there was a significant correlation between digestive problems and sick days. When it came to digestive problems depending which clinic common cold patients decided to go to, there was no significant value because of little data collection. However, while 41.9% of the group who went to hospital at first and then to Koean medicine clinic had digestive problems, 24.2% of the group who directly went to Koean medicine clinic had digestive problems. On the whole, 66.1% of the entire common cold patients were shown to have digestive problems. Conclusion : There are relatively many patients with digestive problems among common cold patients, and there is a significant correlation between digestive problems and sick days on common cold.

Background and Purpose: Subjective cognitive decline (SCD) may be the first symptomaticstage of Alzheimer's disease (AD). Hence, a screening tool to characterize the patients'complaints and assess the risk of AD is required. We investigated the SCD neuroimagingbiomarker distributions and the relevance between the self-report questionnaire andAlzheimer's pathologic changes. Methods: Individuals aged 50 and above with consistent cognitive complaints withoutany objective cognitive impairments were eligible for the study. The newly developedquestionnaire consisted of 2 parts; 10 questions translated from the ‘SCD-plus criteria’and a Korean version of the cognitive failure questionnaire by Broadbent. All the subjectsunderwent physical examinations such as blood work, detailed neuropsychological tests,the self-report questionnaire, brain magnetic resonance imagings, and florbetaben positronemission tomography (PET) scans. Amyloid PET findings were interpreted using both visualrating and quantitative analysis. Group comparisons and association analysis were performedusing SPSS (version 18.0). Results: A total of 31 participants with SCD completed the study and 25.8% showedpositive amyloid depositions. The degree of periventricular white matter hyperintensities(WMH) and hippocampal atrophy were more severe in amyloid-positive SCDs compared tothe amyloid-negative group. In the self-reported questionnaire, the ‘informant's report adecline’ and ‘symptom's onset after 65 years of age’ were associated with more Alzheimer'spathologic changes. Conclusions: Amyloid-positive SCDs differed from amyloid-negative SCDs on WMH,hippocampal atrophy, and a few self-reported clinical features, which gave clues on theprediction of AD pathology.

Modern male has displayed an increased desire to express their social influence and image, and the male fashion market has had to provide various styles and images to fill these needs. The current domestic menswear market, however, is unable to satisfy the needs of male consumers who have a need for diversity in a rapidly changing society; more segmented fashion images and styles are needed. The purposes of this study are to classify fashion images and to establish character of the types. This study was done by performing a literature review and a survey. This study proposed 10 categories of fashion style images. Men’s fashion style is classified into the classic image, sophisticated image, urban casual image, chic modern image, mods modern image, basic casual image, ethnic image, avant-garde image, active & outdoor image, and street-kitsch image. In the case of the classic images, common in formal setting, men’s formal wear is the main focus with the classic suit. The sophisticated image is that of a colorful formal wear seasoned with elegance. Urban casual image is contemporary image, and therefore is meant for city life wear. Chic and modern image conveys an urban image by seeking a simple and chic feel. Mods modern image is retro yet dandy, giving off a sense of youthfulness compared to the other classic images. Ethnic image expresses the exotic quality of folklore as the main representatives of the character casual wear. Avant garde image portrays strong character casual wear with oversized silhouettes or exaggerated details. Active & Outdoor image is leisure life wear conveying active, functional images. Street Kitsch image is men’s street casual wear with graphic patterns such as pop art and graffiti. This study’s significance lies in its presentation of fashion style data, which can be utilized in the design and marketing of fashion targeted to males.
