The main objective of this research was to investigate the characteristics of achromatic & chromatic color coordination of contemporary female fashion by reviewing 'pre-a-porter Collections' of four collections (i. e. cities) - Paris, Milan, New York, London - from the periods of 2002 S/S to 2006/7 A/W. The data was collected by reviewing 'pre-a-porter Collections' magazine and total 677 observations were made. Statistical analysis of frequency and also qualitative interpretation of achromatic & chromatic color coordination characteristics were completed. The main findings were; (1) The achromatic & chromatic color coordination was identified as one of most used color coordination in contmeporary women's fashion collections. (2) Black and white mainly used for achromatic color, and brown used the most often, then followed by blue, red, yellow, green and the others for chromatic color in achromatic & chromatic coordination of contmeporary women's fashion collections. (3) The characteristics of achromatic & chromatic color coordination of modern women's fashion collections from 2002 S/S to 2006/07 A/W showed various images according to chromatic colors and tone variation. The combination of achromaticand brown color variations produced an intelligent and sophisticated image. The soft or light chromatic color and chromatic color combination projected soft, feminine and subtle feeling, while the combination of vivid or strong chromatic color and achromatic color projected a clean and strong feeling through contrasting tones of clear and bright colors. The chromatic color of deep or dark tone and black combination demonstrated supernatural and gloomy image. (4)In all four collections, Paris showed most use of two color coordination and then followed by Milan, N.Y, and London. N.Y showed higher rate of using achromatic & chromatic color coordination, and then followed by Paris, London and Milan.

Purpose: The aim of the present study was to retrospectively investigate the influence of potential risk indicators on the development of peri-implant disease. Methods: Overall, 103 patients referred for implant treatment from 2000 to 2012 were randomly enrolled. The study sample consisted of 421 conventional-length (>6 mm) non-turned titanium implants that were evaluated clinically and radiographically according to preestablished clinical and patient-related parameters by a single investigator. A non-parametric Mann-Whitney U test or Kruskal-Wallis rank test and a logistic regression model were used for the statistical analysis of the recorded data at the implant level. Results: The diagnosis of peri-implant mucositis and peri-implantitis was made for 173 (41.1%) and 19 (4.5%) implants, respectively. Age (${\geq}65$ years), patient adherence (professional hygiene recalls <2/year) and the presence of plaque were associated with higher peri-implant probing-depth values and bleeding-on-probing scores. The logistic regression analysis indicated that age (P=0.001), patient adherence (P=0.03), the absence of keratinized tissue (P=0.03), implants placed in pristine bone (P=0.04), and the presence of peri-implant soft-tissue recession (P=0.000) were strongly associated with the event of peri-implantitis. Conclusions: Within the limitations of this study, patients aged ${\geq}65$ years and non-adherent subjects were more prone to develop peri-implant disease. Therefore, early diagnosis and a systematic maintenance-care program are essential for maintaining peri-implant tissue health, especially in older patients.

Purpose: The aim of the present study was to evaluate the healing of post-extraction sockets following alveolar ridge preservation clinically, radiologically, and histologically. Methods: Overall, 7 extraction sockets in 7 patients were grafted with demineralised bovine bone mineral and covered with a porcine-derived non-crosslinked collagen matrix (CM). Soft tissue healing was clinically evaluated on the basis of a specific healing index. Horizontal and vertical ridge dimensional changes were assessed clinically and radiographically at baseline and 6 months after implant placement. For histological and histomorphometric analysis, bone biopsies were harvested from the augmented sites during implant surgery 6 months after the socket preservation procedure. Results: Clinically, healing proceeded uneventfully in all the sockets. A trend towards reduced horizontal and vertical socket dimensions was observed from baseline to the final examination. The mean width and height of resorption were 1.21 mm (P=0.005) and 0.46 mm (P=0.004), respectively. Histologically, residual xenograft particles ($31.97%{\pm}3.52%$) were surrounded by either newly formed bone ($16.02%{\pm}7.06%$) or connective tissue ($50.67%{\pm}8.42%$) without fibrous encapsulation. The CM underwent a physiological substitution process in favour of well-vascularised collagen-rich connective tissue. Conclusions: Socket preservation using demineralised bovine bone mineral in combination with CM provided stable dimensional changes of the alveolar ridge associated with good reepithelialisation of the soft tissues during a 6-month healing period.

This study was intended to analyze and investigate a diversity of aesthetic values expressed in the military look of the Milan collections by using content analysis method to find what design characteristic and image emerged concretely in the later 20th century. A total of 334 military look works shown in fashion magazines such as Vogue and Collezioni Donna over the period between 1996 and 2000 were collected as research data, which were classified into 5 categories such as item, silhouette, color, color coordination, fashion image. The results were summarized as follows: first, it was found that coat was the most preferred item in expressing the military look image. Second, it was found that the straight line was the most preferred silhouette, which indicates that it was the most suitable silhouette in expressing the bisexual image of the military look. Third, in the colors of the military look, achromatic colors such as black and white were found to be of the highest frequency, which shows that achromatic colors continued to be proposed as fashionable colors around 1996 and this influence was reflected in the military look. Finally, in terms of the item of color coordination, monochromatic coordination accounted for more than half of the military look, through which it could be explained that designers utilized it greatly to make an effective expression of the masculine image.

Ethnic fashion and makeup were studied. 264 fashion designs from pret-$\`{a}$-porter collections in Milan and New York from 2001 S/S to 2005 F/W were analyzed. The major conclusions of the study are as the following: 1. The major types of ethnic fashion and makeup were Africa. American Indian. Japan, India. China and Inca. Makeup types expressed in ethnic fashion were soft smoky, smoky, retro, nature, avant-garde, eastern. 2. Makeup types expressed in ethnic fashion were used for the image for the designer's collections rather than ethnic features. Soft smoky and smoky makeup types were more used than others. 3. Soft smoky makeup types were more expressed in S/S seasons than in F/W seasons. In F/W seasons soft smoky and smoky makeup types were more expressed than other types. 4. Soft smoky and smoky makeup types were more expressed than others in Milan and New York collections commonly. 5. To emphasize the ethnic image for ethnic fashion, ethnic makeup arts like China, Japan, India, Africa, American Indian, Inca makeup arts and soft smoky, smoky makeup arts were represented.

Background: The prognosis of patients with hepatocellular carcinoma (HCC) after curative resection varies greatly. Few studies had investigated the risk factors for early recurrence (recurrence-free time ${\leq}$ 1 year) of hepatitis B virus (HBV)-related HCCs meeting Milan criteria. Methods: A retrospective analysis was performed on the 224 patients with HCC meeting Milan criteria who underwent curative liver resection in our center between February 2007 and March 2012. The overall survival (OS) rate, recurrence-free survival (RFS) rate and risk factors for early recurrence were analyzed. Results: After a median follow-up of 33.3 months, HCC reoccurred in 105 of 224 patients and 32 died during the period. The 1-, 3- and 5-year OS rates were 97.3%, 81.6% and 75.6% respectively, and the 1-, 3- and 5-year RFS rates were 73.2%, 53.7% and 41.6%. Cox regression showed alpha-fetoprotein (AFP) > 800 ng/ml (HR 2.538, 95% CI 1.464-4.401, P=0.001), multiple tumors (HR 2.286, 95% CI 1.123-4.246, P=0.009) and microvascular invasion (HR 2.518, 95% CI 1.475-4.298, P=0.001) to be associated with early recurrence (recurrence-free time ${\leq}$ 1-year) of HCC meeting Milan criteria. Conclusions: AFP > 800 ng/ml, multiple tumors and microvascular invasion are independent risk factors affecting early postoperative recurrence of HCC. In addition resection appears capable of replacing liver transplantation in some situations with safety and a better outcome.
