본 연구의 목적은 소셜미디어에서 공유되는 지오태그 이미지를 활용하여 이용자가 인지하는 북한산국립공원의 경관미를 평가하는 방법을 제시하는 것이다. 연구에서 제시된 평가 방법은 크게 지오태그 이미지 데이터의 수집, 경관 이미지 식별, 조망대상 확률 지수를 적용한 누적가시도 분석의 과정으로 진행되었다. 본 연구에서 데이터로 사용한 램블러(Ramblr)는 국내에서 많은 이용자를 보유하고 있는 아웃도어 활동 지원 어플리케이션으로, 이로부터 북한산국립공원에 대한 총 110,954장의 지오태그 이미지를 수집하여 경관미 평가에 활용하였다. 수집된 지오태그 이미지들은 Google Vision API를 활용해 이미지의 내용을 해석하였으며, 이후 군집분석을 통해서 전체 수집한 사진을 총 11개의 경관이미지 유형과 9개의 비경관이미지 유형으로 구분하였다. 추출한 경관이미지를 바탕으로 북한산국립공원의 경관 유형을 분석한 결과, 봉우리나 산맥과 같은 지형적 특성과 관련한 이미지 유형이 가장 많은 비중을 차지하였으며, 그 외 임내 경관, 단풍경관, 수경관이 주요한 경관 유형으로 발견되었다. 도출된 경관미 평가맵에서는 이러한 주요 경관 유형의 비중과 특성에 따라 표고 및 경사가 높을수록 전반적으로 높은 경관미를 보였다. 그러나 일부 저지대 및 완경사를 지닌 진입지역에서도 높은 경관미가 확인되었다. 또한 북한산 지역이 도봉산 지역보다 경관미가 높게 평가되었으며, 도봉산 지역의 경우에는 표고 및 경사가 높음에도 불구하고, 상대적으로 낮은 경관미가 확인되었다. 이는 경관미가 물리적인 환경 조건뿐만 아니라, 경관을 조망하는 탐방객들의 휴양 활동과도 크게 관계하고 있음을 보여준다. 이처럼 지오태그 이미지의 누적 가시도를 활용한 경관미 평가는 사람들의 인식에 기반한 경관적 가치를 지리적으로 이해하고, 그 편차를 식별할 수 있도록 함으로써 향후 북한산국립공원의 경관 계획 및 관리에 유용하게 활용될 수 있을 것으로 기대된다.

The purpose of this paper is to analyze the relationship between panoramic perception and space organization for restoration of urban environment and architecture. Panorama is a collective visual catalogue composed by series of perspective images. It is a product from continuous movements of viewer by defamilarizing real image and structuring order between city and building. Through understanding the panoramic image, the viewer is able to achieve the total image of the city. For example, achieving visual perception of the city by employing the panoramic view from different historical backgrounds and cultures, Berlin developed its urban characteristic by rebuilding panoramic view as an aesthetic device. First, this paper mention theory of panorama as an aesthetic device for shaping the city from the building. Second, this paper analyze the relationships between characteristics of panorama and historical contexts for why those panoramic views are valuable by mentioning the Altes Museum, the Berlin National Gallery, Museum of Modern Literature, and Folkwang Museum of panoramic view. In conclusion, this paper argues that visual perception such as panoramic view is the valuable device for organizing the image of the city's own identity. Constructing vision of each city influences not only shaping the city but also mapping the mental views of the building. Also, historical conditions and open spaces are one of the inherent elements combined with panoramic view for establishing urban identity. In search for good place making, it is important to understand the role of the historical context and fabric plan in shaping how a resident sees - literally, sees- their city with buildings. Berlin serve as excellent counter example in how the valuable place making panoramic mental views of urbanities take shape.

Recent beauty trends focus on suitability to individual features. A personal color system is a recent aesthetic concept that influences color make up and coordination. However, a personal color concept has several weaknesses. For example, type classification is qualitative and not quantitative because its measuring system is a sensory test with no industry standard of personal color system. A quantitative personal color type classification model is the purpose of this study, which can be a solution to above problems. This model is a kind of mapping system in a 3D Cartesian coordinate system which has own axes, Value, Saturation, and Yellowness. The cheek color of the individual sample is also independent variable and personal color type is a dependent variable. In order to construct the model, this study conducted a colorimetric survey on a 993 sampling frequency of Korean women in their 20s and 30s. The significance of this study is as follows. First, through this study, personal color system is established on quantitative color space; in addition, the model has flexibility and scalability because it consisted of independent axis that allows for the inclusion of any other critical variable in the form of variable axis.

Purpose: Masseter muscle is an important muscle of mastication. Because it has a great influence on the shape of low facial contour, patients who have masseteric hypertrophy show square-shaped jaw appearance. As aesthetic procedures for the reduction of the masseter muscle volume, radiofrequency ablation or botulinum toxin injection is at the center of attention. Authors studied the anatomical measurement of the thickness and width of masseter muscle and the surface mapping of the maximal thickness point using computed tomography (CT) scan to identify the useful guide for the injection of botulinum toxin in masseteric hypertrophy patients. Methods: We analyzed 2 mm-thickness OMU (ostiomeatal unit) CT of 112 normal people (224 masseter muscles) taken from June 2009 to May 2010. First, we measured the thickness, width and depth of the masseter muscle from the skin surface and analysed each by side, sex and age, respectively. The distribution of the thickness of the muscle and the correlation of thickness and width of the muscle were studied also. Second, we underwent surface mapping of the maximal thickness point using CT analysis by means of checking the vertical and horizontal distance from the angle of the mandible. Results: The average thickness and width of the masseter muscle was 17.73 mm and 40.78 mm in the male patients and were 14.33 mm and 37.42 mm in the female patients. Statistically, both figures of the male patients were larger than those of the female patients. However, the depth of the muscle from the skin surface in female patients (7.37 mm) was larger than that of the male patients (6.15 mm). There were no statistical difference in side or age. The width and thickness of the masseter muscle were in the positive correlation. The location of maximal thickness point of the masseter muscle was 27.77 mm vertically and 27.68 mm horizontally in the male patients, and 25.19 mm vertically and 25.42 mm horizontally in the female patients from the angle of mandible. Conclusion: We were able to present statistical evidence of the diagnosis and treatment of the masseteric hypertrophy regarding the anatomical measurements such as the thickness and width. And the maximal thickness point of the masseter muscle may be a useful guide for the clinical procedures of botulinum toxin injection.

Nowadays computer-guided "flapless" surgery for implant placement using templates is gaining popularity among clinicians and patients. The advantages of this surgical protocol are its minimally invasive nature, accuracy of implant placement, predictability, less post-surgical discomfort and reduced time required for definitive rehabilitation. Aim of this study is to describe the digital implant protocol, thanks to which is now possible to do a mini-invasive static guided implant surgery. This is possible thanks to a procedure named surface mapping based on the matching between numerous points on the surface of patient's dental casts and the corresponding anatomical surface points in the CBCT data. With some critical points and needing an adequate learning curve, this protocol allows to select the ideal implant position in depth, inclination and mesio-distal distance between natural teeth and or other implants enabling a very safe and predictable rehabilitation compared with conventional surgery. It represents a good tool for the best compromise between anatomy, function and aesthetic, able to guarantee better results in all clinical situations.

The purpose of this study was to serve as a basis for mapping out successful strategies to build the professional self-image of nurses through uniform, by examining their satisfaction with uniform and professional self-image by general characteristics, and identifying the correlational relationship between the two factors. The subjects in this study were 205 nurses who served in general departments of two university hospitals in Seoul. The departments where special uniform was required, including ICU, RR, OR and CSR, were excluded. The data were collected from September 15 through 22, 2000. For measurement of uniform satisfaction level, a uniform satisfaction scale was prepared by myself, and Arthur(1990)'s PSCNI translated and modified by Song Kyong Ae and Rho Chun Hee(1996) was employed. The Cronbach a of the uniform satisfaction scale and PSCNI was 0.90 and 0.86 respectively. The collected data were analyzed by SAS, and real number, percentage, average and standard deviation were calculated. Besides, t-test, one-way ANOVA, Pearson's r procedures were utilized, and Scheffe test was conducted as a posttest. The findings of this study were as below: 1. The uniform satisfaction of the nurses investigated was scored 2.52 on the basis of 4 points, which was on the medium level. By subarea, symbolicity satisfaction was 2.48, and aesthetic satisfaction was 2.60. The functionability satisfaction was 2.44. So the esthetic satisfaction was greatest. 2. Among general characteristics of the subjects, two factors made a significant difference to their uniform satisfaction : age(F=4.05, P=.0189), and total career(F=4.25, P=.0061). 3. Their professional self-image got 2.75 on the basis of 4 points, which was on upper middle level. The subarea score was 2.79 for professional work, 2.52 for satisfaction and 2.97 for communication. The communication area was rated highest, and the satisfaction area was scored lowest. 4. Among the general characteristics of the subjects, professional self-image was different according to five factors : age(F=17.83, P=.001), marital status(T=5.18, P=.0000), educational background(F=8.72, P=.0002), position(T=-5.29, P=.0000) and total career(F=15.23, p=.0001). Better professional self-image was possessed by the older group than the younger one, by the married group than the singles, by the better-educated group than the less-educated, by the nurses in position equal to or higher than charge nurse, or by the higher-career group. 5. The correlational relationship of uniform satisfaction to professional self-image was statistically significant, yet very weak(r=.1978, p=.0045). The satisfaction area of professional self-image was correlated to every uniform satisfaction area, including symbolicity(4=.4393, p=.0001), aesthetics(r=.2471, p=.0004), functionability(r=.3094, p=.0001) and total satisfaction(r=.4050, p=.0001). Therefore, the uniform satisfaction gave an impact on the satisfaction area of professional self-image of the nurses, and there was a significant correlational relationship between uniform symbolicity area and total professional self-image(r=.2416, p=.0005).
