Background: The purposes of the present study were to compare implant stabilities of mandibular block bone graft and bovine bone graft and to evaluate influencing factors for implant stability in mandibular block bone (MBB) graft. Methods: This retrospective study investigated 1224 cases and 389 patients treated by one surgeon in the Department of Oral and Maxillofacial Surgery of Pusan National University Dental Hospital (Yangsan, Korea) between January 2010 and December 2014. Proportions that MBB graft cases constitute in all implant restoration cases and in all bone graft cases were measured. Implant stability quotient (ISQ) values were achieved by the same surgeon before loading. The average ISQ values of the experimental groups were compared. In addition, ISQ values of influencing factors, such as age, sex, implant size, and implant placement site, were compared within the MBB group using $Osstell^{TM}$ Mentor ($Osstell^{(R)}$, $G{\ddot{o}}teborg$, Sweden). Paired t test and ANOVA were conducted for statistical analysis with a significance level of 0.05. Results: Fifty-five percent of all implant restoration cases performed bone graft while MBB cases constituted 34% of all implant restoration cases and 61% of all bone graft cases. Comparing ISQ values according to bone graft materials, the MBB group manifested sufficient implant stability by presenting comparable ISQ value to that of the experimental group without bone graft. Among the reviewed factors, females, mandibular molar regions, and implants in larger diameter displayed greater implant stabilities. Conclusions: Satisfactory implant stability was accomplished upon administration of MBB graft. Within the limitation of this study, gender, implant site, and implant diameter were speculated to influence on implant stability in MBB graft.

Objective: To investigate the differences in oral health-related quality of life (OHRQoL) and self-reported jaw function between patients with hyperdivergent and normodivergent facial types. Methods: Eighty patients with a distinctively hyperdivergent facial type (mandibular plane angle greater than 2 standard deviations, or $42^{\circ}$) and 80 controls were individually matched according to age, sex, ethnicity, and treatment stage. Data were collected using self-report questionnaires such as the Oral Health Impact Profile (OHIP-14) and Jaw Functional Limitation Scale (JFLS-8). Results: The mean age of the patients was $17.2{\pm}4.6years$ (range, 12-49 years), with most (65.0%) being female and of New Zealand European origin (91.3%). Individuals with hyperdivergent facial types had higher overall and social domain scores on the OHIP-14 (p < 0.05) than did the ones with normodivergent facial types. However, the intergroup differences in JFLS-8 scores were not significant (p > 0.05). Conclusions: Jaw function appears to be similar in individuals with hyperdivergent and normodivergent facial morphologies. However, those with hyperdivergent facial types are more likely to self-report poorer OHRQoL than are those with normal faces, especially in relation to social aspects.

Most systems in ubiquitous computing analyze context information of users which have similar propensity with demographics methods and collaborative filtering to provide personalized recommendation services. The systems have mostly used static context information such as sex, age, job, and purchase history. However the systems have limitation to analyze users' propensity accurately and to provide personalized recommendation services in real-time, because they have difficulty in considering users situation as moving path. In this paper we use users' moving path of dynamic context to consider users situation. For the prediction accuracy we complete with a path completion algorithm to moving path which is inputted to RSOM. We train the moving path to be completed by RSOM, analyze users' moving pattern and predict a future moving path. Then we recommend the nearest product on the prediction path with users' high preference in real-time. As the experimental result, MAE is lower than 0.5 averagely and we confirmed our method can predict users moving path correctly.
Background: The one-person households (OPH) are rapidly increasing and vulnerable to socioeconomic and health problems. Because it is predicted to be inequitable to health care utilization, we would like to find out about the equity of health care utilization of the OPH by comparison with the multi-person households (MPH). Methods: This study followed the theoretical framework of Wagstaff and van Doorslaer (2000), O'Donnell and his colleagues (2008), where the horizontal inequity index is the difference between the concentration indices of actual health care utilization and health care needs. This study employed the 9th Korea Health Panel survey, and a total of 10,807 cases were analyzed. Health care needs were measured by age, sex, subjective health status, chronic disease count, Charlson's Comorbidity Index, limitation of activities, and disability. Results: Compared with the MPH, there were pro-poor inequities in hospitalization, emergency utilization, hospitalization out-of-pocket payments, and pro-rich inequities in outpatient out-of-pocket payments for the OPH. The decomposition of the concentration index revealed that chronic disease count made the largest contribution to socioeconomic inequality in outpatient utilization. Age, health insurance, economic activities, and subjective health status also proved more important contributors to inequality. The variables contributing to the hospitalization and emergency utilization inequity were age, education, Charlson's Comorbidity Index, marital status, and income. Conclusion: Because the OPH was more vulnerable to health problems than the MPH and there were pro-poor inequities in medical utilization, hospitalization, and emergency costs, it is necessary to develop a policy that can correct and improve the portion of high contribution to medical utilization of the OPH.

Purpose: We perform an analysis of infection risk factors for fracture patients and confirm that the risk factors reported in previous studies increase the risk of actual infection among fractured patients. In addition, injury severity score (ISS) which is used as an evaluation tool for morbidity of trauma patients, confirms whether there is a relationship with infection after orthopedic fracture surgery. Methods: We retrospectively reviewed 1,818 patients who underwent fixation surgery at orthopedic trauma team, focused trauma center from January 1, 2015 to December 31, 2017. Thirty-five patients were infected after fracture surgery. We analyzed age, sex, open fracture criteria based on Gustilo-Aderson classification 3b, anatomical location (upper extremity or lower extremity) of fracture, diabetes, smoking, ISS. Results: Of 1,818 patients, 35 (1.9%) were diagnosed with postoperative infection. Of the 35 infected patients, nine (25.7%) were female and five (14.0%) were upper extremity fractures. Three (8.6%) were diagnosed with diabetes and eight (22.8%) were smokers. Thirteen (37.1%) had ISS less than nine points and six (17.1%) had ISS 15 points or more. Of 1,818 patients, 80 had open fractures. Surgical site infection were diagnosed in 12 (15.0%) of 80. And nine of 12 were checked with Gustilo-Aderson classification 3b or more. Linear logistic regression analysis was performed using statistical analysis program Stata 15 (Stata Corporation, College Station, TX, USA). In addition, independent variables were logistic regression analyzed individually after Propensity scores matching. In all statistical analyzes, only open fracture was identified as a risk factor. Conclusions: The risk factors for infection in fracture patients were found to be significantly influenced by open fracture rather than the underlying disease or anatomical feature of the patient. In the case of ISS, it is considered that there is a limitation. It is necessary to develop a new scoring system that can appropriately approach the morbidity of fracture trauma patients.
Ella Hepworth Dixon's The Story of a Modern Woman is a pioneering female writer?s important work which was not deeply studied yet very influential in new women literature and its cultural global impact. Although women had been often praised for their beauties specially by romantic poets but their self-realization and innate values were not widely recognized until new women writers advocated their desires and active roles in the society at the end of the $19^{th}$ century. The new women writers including Ella Dixon gained popularity with their professional skills as the journalists or the contributors to the journals which were suddenly popular and actively circulated among Victorian women. From the 1880s to 1920s, in contrast with the traditional images of wives as ?the angel in the house?, these women new women writers broke the yoke of subjugated womanhood and instead tried to freely express their independent spirits and demanded their roles in the society. Although they were criticized sometimes as "the daughter of a new guise" "a lady of restless sex" or "the wild women," new girls? perky images in new women fiction brought into the new cultural phenomenon which led to the ?flapper? girl in the 1920s. Ella Dixon?s protagonist Mary Erle, strikingly similar to author herself, was a representative new woman who displayed a wide range of new cultural perspectives from a feminist?s viewpoint, but her untimely desire in the capitalized society was not fully accomplished, just promising the potentiality of the female solidarity which might be achieved later by her feminist posterity.
This paper attempts an allegorical reading of female sexuality in Henry James' The Aspern Papers, wherein the narrator reveals his obsession with the love letters of the dead poet, Jeffrey Aspern. Not only the old papers, but does he also fetishize female protagonists in order to maintain his belief in the "great poet." Discussing such fetishistic elements in the novella is in order firstly to reveal the self-splitting logic of phallocentric language, and secondly to analyze the limitation of such language, which resonates with the Freudian construction of female sexuality as critically presented by Irigary. The first part of this study explains the binary structure of The Aspern Papers crystalized in the symbolic courtship in the Bordereaus' garden. It also represents the psychological mindset of the narrator/protagonist: symbolically located "outside," the narrator describes the two Bordereaus as being closed "inside" in a dark mansion, concealing the precious papers from him and the public. In other words, the women are nothing but the obstacle for the self-elected agent, the narrator, from the publication of the language and ideas of the "great man". The women are associated with secrecy and surreptitiousness, while the man with transparency and the truth. Second part of this paper mimics this In/Out binary as a means to reveal insufficiency, if not impropriety, of the predominant discourse of female sexuality constructed and controlled from the male perspective. Employing Irigary's argument, this paper reads the female characters as allegory for female sexual organs, which explains the narrator's inevitable failure. That is, female sexuality is something that cannot be articulated by the intruding language of a masculine subject. since the female sex as such is not only plural but also harmonious and self-contained,

Purpose: This study is to investigate the distribution of natural tooth shades in the Korean elderly population to quantify the correlation and changes of tooth color with age and gender. In addition, the possible effects of habits on tooth color were assessed. Materials and Methods: The tooth color of one of the maxillary central incisors of 200 Korean individuals aged 50 to 89 years, males and female, was measured using the portable intraoral spectrophotometer (VITA Easyshade V). CIELab and CIELCh color coordinates were recorded. We conducted the survey about the tobacco smoking, chronic disease, medication, eating habits, oral health behaviors and satisfaction with tooth color. Experimental data were statistically analyzed by using the t-test (P<0.05), two-way analysis of variance and Pearson's correlation test. Result: The most frequent color in the Korean elderly population was 3M3 & A3.5 shade. L* and h* values decreased, whereas C*, a* and b* values increased progressively with age. There was a significant interaction between age and color coordinates for b* values (r=0.245, P<0.05). Males generally have significantly higher C*, a*, b* values and lower L*, h* value compared to females. Individuals who consumed alcohol had a higher L* value (P<0.05). Conclusion: Within the limitation of this study, the central incisors were getting darker, more reddish, and yellowish with age. Information on the chromatic range of natural teeth by age and gender could help to select colors for esthetic dental restorations.
Purpose: This systematic review investigated whether drug use is associated with the presence of oral lesions and periodontitis. Methods: A search was performed for studies that analyzed the presence of periodontitis and/or oral lesions in users of crack, cocaine, and/or marijuana in the PubMed, Scopus, and Web of Science databases. Observational studies in English, Spanish, or Portuguese, without limitation of year, age, and sex, were included. Studies that did not evaluate periodontitis and oral lesions according to the eligibility criteria were excluded. Two authors independently performed study selection and data extraction using a standardized form. The risk of bias of studies included in the meta-analysis was assessed using the Joanna Briggs Institute Critical Appraisal Checklist. The meta-analysis included studies that investigated the association of drug use with the outcome. Results: The initial search resulted in 9,279 articles, from which 16 studies with 15,434 participants were included in the review and 8 studies were included in the meta-analysis. Most studies that evaluated periodontitis in drug users and non-users found a positive association in users. Most studies that analyzed oral lesions reported a higher prevalence, association, or risk of oral lesions in drug users than in non-users. A critical evaluation identified a need to improve the control and reporting of confounding factors in studies on this topic. An association was found between periodontitis and the use of crack, cocaine, and/or marijuana (odds ratio [OR], 1.84; 95% confidence interval [CI], 1.04-3.27; P=0.04) and between oral lesions and the use of these drugs (OR, 2.13; 95% CI, 1.58-2.86; P<0.001). Conclusions: Drug users are more likely to develop oral lesions and periodontitis than nonusers. However, the results should be interpreted with caution, considering the heterogeneity and quality of the studies included in the analysis.

Objectives: This study was to identify socioeconomic factors and health-related behaviors influencing on HRQOL(health-related quality of life) for the older adults in rural area. Methods: 483 subjects aged over 65 years responded a direct interview, which covered HRQOL, BMI, socioeconomic characteristics, and health-related behaviors including smoking, drinking, and exercise. Results: Overall, the mean number of healthy days were 15.1 days and not significantly different by sex. Men didn't show a significant difference in HRQOL by age group. But women reported lower levels of healthy days and higher levels of activity limitation and physical unhealthy days with increasing age. Results from ANCOVA showed HRQOL to be significantly associated with education, job, and family type. Men presented no significant difference in HRQOL by health-related behaviors, but women who have been drinking, or have less number of chronic diseases reported higher mean healthy days and lower activity limitation days, physical unhealthy days, and mental unhealthy days. Older adults who reported good to excellent self-rated health were higher healthy days and lower activity limitation, physical unhealthy days, and mental unhealthy days than those who reported fair to poor health status. Conclusions: The HRQOL for the older adults in rural area was related to socioeconomic characteristics, health-related behaviors and self-rated health status. A better understanding of factors related to HRQOL would help to improve the older adults' quality of life.
