Purpose: Marginal bone loss (MBL) is an important clinical issue in implant therapy. One feature that has been cited as a contributing factor to this bone loss is peri-implant mucosal thickness. Therefore, in this report, we conducted a systematic review of the literature comparing bone remodeling around implants placed in areas with thick (≥2-mm) vs. thin (<2-mm) mucosa. Methods: A PICO question was defined. Manual and electronic searches were performed of the MEDLINE/PubMed and Cochrane Oral Health Group databases. The inclusion criteria were prospective studies that documented soft tissue thickness with direct intraoperative measurements and that included at least 1 year of follow-up. When possible, a meta-analysis was performed for both the overall and subgroup analyses. Results: Thirteen papers fulfilled the inclusion criteria. A meta-analysis of 7 randomized clinical trials was conducted. Significantly less bone loss was found around implants with thick mucosa than around those with thin mucosa (difference, -0.53 mm; P<0.0001). Subgroups were analyzed regarding the apico-coronal positioning, the use of platform-matched vs. platform-switched (PS) connections, and the use of cement-retained vs. screw-retained prostheses. In these analyses, thick mucosa was found to be associated with significantly less MBL than thin mucosa (P<0.0001). Among non-matching (PS) connections and screw-retained prostheses, bone levels were not affected by mucosal thickness. Conclusions: Soft tissue thickness was found to be correlated with MBL except in cases of PS connections used on implants with thin tissues and screw-retained prostheses. Mucosal thickness did not affect implant survival or the occurrence of biological or aesthetic complications.

Objectives: The purpose of this study was to evaluate program methods for effective smoking cessation and prevention through systematic review of studies published during recent 3 years in Korea. Methods: Electronic searches were conducted in DBPIA, RISS, KISS and other databases looking for studies published from 2010 to 2012 that dealt with the effects of intervention on smoking prevention and cessation. A total of 25 studies were included in the final analysis. Three independent reviewers critically evaluated the study quality and evidence of effectiveness based on The Community Guide methodology. Results: Multi-component intervention showed strong evidence of effectiveness for adolescents and sufficient evidence for patient smokers. Cognitive-behavioral intervention for adolescents and child-parent interaction program for adults demonstrated sufficient evidence of effectiveness on the smoking cessation and its determinants. There was insufficient evidence showing effectiveness of smoking prevention programs. Conclusion: Improving the quality and quantity of the intervention studies on smoking could help to expand evidence base for effective intervention methods and strategies on smoking.

The electronic commerce site (EC site) has become an important marketing channel where consumers can purchase many kinds of products; their access logs, including purchase records and browsing histories, are saved in the EC sites' databases. These log data can be utilized for the purpose of web marketing. The customers who purchase many product items are good customers, whereas the other customers, who do not purchase many items, must not be good customers even if they browse many items. If the attributes of good customers and those of other customers are clarified, such information is valuable as input for making a new marketing strategy. Regarding the product items, the characteristics of good items that are bought by many users are valuable information. It is necessary to construct a method to efficiently analyze such characteristics. This paper proposes a new latent class model to analyze both purchasing and browsing histories to make latent item and user clusters. By applying the proposal, an example of data analysis on an EC site is demonstrated. Through the clusters obtained by the proposed latent class model and the classification rule by the decision tree model, new findings are extracted from the data of purchasing and browsing histories.

Objectives : This review aims to assess the effect of Wuqinxi exercise for osteoporosis. Methods : We searched 9 electronic databases(Pubmed, EMBASE, Cochrane Library, CAJ, Oasis, KISS, NDSL, KMBASE, KISTI) and related 2 journals until November 2017. We included randomized controlled trials(RCTs) of testing Wuqinxi exercise for osteoporosis. The methodological quality of RCTs related assessed by the Cochrane risk of bias tool. Results : 12 RCTs were eligible in our inclusion criteria. No statistical differences were found between the Wuqinxi versus no intervention, Wuqinxi plus antiosteoporosis medications versus antiosteo-porosis medications on lumbar spine, femora bone mineral density (BMD). However, Wuqinxi significantly improved lumbar spine BMD compared with antiosteoporosis medications (P < 0.00001). Additionally, the results showed a remarkable effect in improving pain score(VAS) when Wuqinxi or Wuqinxi plus antiosteoporosis medications (P < 0.0005) was used. Conclusions : There is evidence of Wuqinxi exercise for osteoporosis with meta-analysis. However, our systematic review has limited evidence to support Wuqinxi exercise for osteoporosis. because of low quality of original articles and further well-designed RCTs should be encouraged.

Background: The effect of mobilization on lumbar back pain has been fully described in several clinical aspects, but evidence for muscle strength would be still less clear. Objective: To assess the effect of lumbar mobilization on lower limb strength in healthy individuals. Methods and Analysis: Healthy people aged 18-65 will be included regardless of race or sex. Original peer-reviewed primary reporting randomized controlled trials (RCTs) will be included. Electronic databases, such as MEDLINE, EMBASE, Cochrane Central Register of Controlled Trials, Web of Science, Pedro, CINAHL, ClinicalTrials.gov will be searched from inception until July 30. Only studies published in English will be included in this review. Two reviewers will complete the screening for eligibility independently, and the other two reviewers will also complete the risks of data extraction and bias assessment independently. Lower Limb strength will be assessed as primary outcome, and particular intervention or participant characteristics will be assessed as the secondary outcomes. Meta-analysis will be conducted using Review Manager 5.3.3, and evidence level will be assessed using the method for Grading of Recommendations Assessment, Development and Evaluation. Outcomes will be presented as the weighted mean difference or standardized mean difference with 95% CI. If I² ≤ 50%, P>.1, the fixed effect model will be used, otherwise, random-effects model will be used. Ethics and dissemination: This review might not be necessary ethical approval because it does not require individual patient's data; these findings will be published in conference presentations or peer-reviewed journal articles. PROSPERO registration number: CRD42020150144.

Purpose: This study was a systematic review and meta-analysis designed to evaluate the effects of breastfeeding intervention on breastfeeding rates. Methods: Based on the guidelines of the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA), a systematic search was conducted using eight core electronic databases and other sources including gray literature from January 9 to 19, 2017. Two reviewers independently select the studies and assessed methodological risk of bias of studies using the Cochrane criteria. The topics of breastfeeding interventions were analyzed using descriptive analysis and the effects of intervention were meta-analyzed using the Review Manager 5.2 software. Results: A total of 16 studies were included in the review and 15 were included for meta-analysis. The most frequently used intervention topics were the importance of good latch-on and frequency of feeding and determining adequate intake followed. The pooled total effect of breastfeeding intervention was 1.08 (95% CI 1.03~1.13). In the subgroup analysis, neither pre-nor post-childbirth intervention was effective on the breastfeeding rates at 1, 3, and 6 months, and neither group nor individual interventions had an effect. Only the 1 month breastfeeding rate was found to be affected by the individual intervention with the persistent strategies 1.21 (95% CI 1.04~1.40). Conclusion: Effective breastfeeding interventions are needed to help the mother to start breastfeeding after childbirth and continue for at least six months. It should be programmed such that individuals can acquire information and specific breastfeeding skills. After returning home, there should be continuous support strategies for breastfeeding as well as managing various difficulties related to childcare.

Objectives: This study is to review the effect of Korean medicinal herbs on treatment of polycystic ovary induced rat models reported in domestic & foreign journals. Methods: 7 electronic databases (Pubmed, CNKI, EMBASE, Oasis, RISS, CENTRAL, Koreankt) were searched with term as polycystic ovary, and study reports on polycystic ovary impairment with Korean medicinal herbs. After selecting several studies, the analysis was focused on items reflected in the Rotterdam criteria for diagnosis of polycystic ovary syndrome such as hyperandrogenism (HA), ovarian weight, the number of follicle cysts, estrous cycles, and etc. Results: 15 studies were reviewed. As a polycystic ovary induction material, estradiol valerate (EV) was used in 9 studies, testosterone propionate (TP) in 2 studies and dihydrotestosterone (DHT), dehydroepiandrosterone (DHEA), Poretsky's method and letrozole (LE) was used in rest 4 studies, respectively. Tribulus terrestris (TT), Nardostachys jatamansi (NJ), Lycii cortex (LC), Cinnamomum cassia kees (CCK) and Atractylodis macrocephalae koidz (AMK) produced statistically significant results related to hyperandrogenism. In ovarian weight, Silybum marianum (SM), AMK and Alllium sativum (AS) were statistically significant. In the the number of follicle cysts, SM and TT were statistically significant. In estrous cycles, AMK, NJ, TT and Coix lacryma-jobi (CL) were statistically significant. Conclusions: Based on the diagnosis criteria of Rotterdam, TT, NJ, AMK, SM, AS, and CL produced statistically significant results in rat model.
