(Background and Purpose) Although outdoor advertising in new towns have conditions enough to improve the urban landscape by actively managing them from the urban planning stage, advertising using large windows in primary colors and excessively uniform design impede the urban landscape as well. Regarding the purposes of this study, first, it aims to derive administrative-level problems by making an analysis of regulations related to outdoor advertising in the target study sites. Second, this study aims to analyze the guidelines related to the design of outdoor advertising and derive the problems of shapes and colors by conducting field surveys. Through this, problems in the management of outdoor advertising in the commercial facilities of new towns will be deduced to propose improvement directions. (Method) First, this study will recognize the roles and problems of outdoor advertising in terms of the urban landscape, and present the research purposes and methods in order to improve them. Second, this study will carry out a literature review to inquire into the guidelines and maintenance related to outdoor advertising of local governments and derive the administrative problems and implications, as well as elements necessary for field surveys and analyses. Third, this study will deduce problems and implications in terms of design by investigating and analyzing outdoor advertising in the target sites through field surveys. Fourth, this study will examine the effectiveness of the guidelines for outdoor advertising, and propose management plans for outdoor advertising to improve the aesthetics of the urban landscape in terms of the administration and design. (Results) Most of the wall signboards in sections A-D apply the same background color in the same building, and the color of the text is fine because its color is similar to the background color. However, since the chroma of the background color and text color is sometimes high, and the explicitness is insufficient, improvements are needed. Most of the window-dependent advertising uses less than two colors, but it uses high-chroma primary colors regardless of the restriction of the size. This study confirmed that this was the greatest cause of the deterioration of the urban landscape. (Conclusions) It is necessary to improve the explicitness of the wall-dependent signboards, and most of the materials for window-dependent advertising are made of cloth or vinyl, which does not cause much damage to property. Therefore, removing them is the most desirable solution. When the removal is not easy, it is required to induce a beautiful urban landscape by regulating the size and colors. In order to ameliorate the design of outdoor advertising in the commercial facilities of new towns, continuous awareness education and public relations for shop owners are needed.

Background and Purpose The prevalence of dementia is increasing in South Korea. Multidomain interventions may be useful for preventing dementia. Such programs need to be disseminated to elderly Koreans throughout the country. We have developed programs of the SoUth Korean study to PrEvent cognitive impaiRment and protect BRAIN health through lifestyle intervention in at-risk elderly people (SUPERBRAIN), which consists of a facility-based multidomain intervention (FMI) program and a home-based multidomain intervention (HMI) program suitable for elderly Koreans. We aim to determine the feasibility of the SUPERBRAIN programs before a large-scale randomized controlled trial. Methods We will recruit 150 participants among those without dementia aged 60–79 years with at least 1 modifiable dementia risk factor. They will be randomly assigned in a 1:1:1 ratio to the FMI, HMI, and the waiting-list control arm. The 6-month multidomain intervention consists of management of metabolic and vascular risk factors, cognitive training and social activity, physical exercise, nutritional guidance, and motivational enhancement programs. The primary outcomes are adherence and retention rates and changes in the total scale index score of the Repeatable Battery for the Assessment of Neuropsychological Status from baseline to the study end. The main secondary outcomes are disability, depressive symptoms, quality of life, vascular risk factors, physical performance, nutritional assessment, and motivation questionnaire. There will be an exploratory evaluation of neurotrophic, neurodegeneration, and neuroinflammation factors, microbiome, telomere length, electroencephalography, and neuroimaging measures. Conclusions The results obtained will provide information on the applicability of these multidomain intervention programs to at-risk elderly people.

Electrical characterization of InAs/GaAs quantum-dot infrared photodiodes

박희경,김은규,이창훈,송진동,이정일,최원준,박용주 한국물리학회 2004 THE JOURNAL OF THE KOREAN PHYSICAL SOCIETY Vol.45 No.1

The electrical properties of InAs/GaAs quantum-dot infrared photodiodes (QDIP) were characterized by capacitance-voltage and deep-level transient spectroscopy measurements. The QDIP structures with self-assembled quantum dots (SAQDs) were grown in atomic layer epitaxy mode by using a molecular beam epitaxy method. The samples had ve-stacked SAQD layers on n+-GaAs substrates. In Si-doped InAs/GaAs QDIP structures, two electron deep levels of EC-0.52 eV with an emission cross section of 2.3 10cm2 and EC-0.57 eV with 4.5 1016 cm2 were observed by DLTS measurements. These two levels are associated with the excited and the ground states in the QD layers, respectively, and are in good agreement with the PL results. An interface state on the low-energy side was also measured, and this may be a source of leakage current.

The Application of the Forensic Dental Identification to Unidentified Individual Remains in Korea

박희경,Park, Hee-Kyung Korean Academy of Orofacial Pain and Oral Medicine 2006 Journal of Oral Medicine and Pain Vol.31 No.1

The cases of unidentified individual remains submitted to Forensic dentistry section in National Institute of Scientific Investigation, Korea were analyzed to study the application of forensic dental identification into individual identification in the period 2002-2005. The identification cases of unidentified remains were 405 out of 493, which accounted about 82% of whole cases. The incidence of submission of skeletons at least including the skull was increased from 58% in 2002 to 80% in 2005. The numbers of cases for the full examinations were 4 times more than that for age estimation in 2005. Twenty-four cases were submitted for skull to photographic superimposition and 15 out of 24 cases were examined, and the other 9 cases were examined by DNA analysis only. The submitted cases for dental comparison were 23 cases, 9 cases were positively identified, 4 cases were possible, 7 cases were excluded, and 3 cases ended up with insufficient evidences. The proportion of positive identification by dental methods was increased gradually from 9% in 2002 to 46% in 2005. Forensic dental identification has become important and useful because the availability of dental records and radiographs has been increasing. Compared to DNA analysis, forensic dental identification has several advantages such as no needs for high cost equipments and low expenses. And the interpretation of results is straightforward and speedy. These advantages are based on using primary their own dental records of the individuals rather than secondary DNA reference samples from family members. The application of the forensic dental identification to unidentified individual remains will be increased because the dental comparison can complement the limitation of DNA analysis and skull to photographic superimposition in many cases. In order to obtain positive identifications of unidentified remains, a close collaboration between the police and forensic scientists is important. The systemic approach including legislation to preserve dental records of unidentified remains and missing persons for the identification of unidentified remains should be needed.

The belief that stress leads to illness has a long history. A number of the orofacial disease are also closely associated with stress. Despite research in the relationship of stress and the orofacial diseases leading to statistically significant correlations, the pathology remains vague. In the present study, the expression of clusterin, a stress protein responsible for antiapoptosis and cytoprotection, under restraint stress condition was observed in the submandibular gland, one of the major salivary glands. Sprague-Dawley rats were divided into 2 groups: normal group and restraint stress group. The rats of restraint stress group were placed in the stress cages and then sacrificed at day 0, 3 and 5 day of the experiment. After that, the submandibular glands of all the rats were excised immediately. The levels of clusterin proteins and mRNA in the tissues were measured by immunohistochemistry and Northern blot analyses, respectively. The results were as follows: 1. In the immunohistochemistry, clusterin protein was detected only immediately after the application of restraint stress. 2. In the restraint stress group, at day 3 and 5, histologically apoptosis was induced with karyorrhectic and pyknotic changes. 3. By the restraint stress, acinic cells were destructed earlier than ductal cells. 4. In the Northern blot, mRNA of clusterin was expressed only immediately after the application of restraint stress. The overall results suggest that as an early response to stress, clusterin is expressed in the glands to protect the glandular cells from the stress. But if stress is so strong and prolonged that it can exceed the stress adaptability of the cells, then the cells may undergo apoptosis instead of producing clusterin.
