Objectives: The aim of this study was to investigate the effectiveness of a hospital-based smoking cessation intervention for increasing continuous abstinence rate from smoking in patients with cerebral infarction. Methods: One-hundred and two smokers with cerebral infarction who decided to quit smoking were enrolled in the smoking cessation intervention from December 2012 to February 2015. The smokers underwent six consecutive times of individual intervention with nurse specialist on smoking cessation including education on behavioral modification, counseling for withdrawal symptoms, and anti-smoking advice over a 12-month period. Results: Among the total participants, the continuous abstinence rate from smoking changed from 79.4% at 1 month to 60.8% at 12 months after discharge. The continuous abstinence rate from smoking after 12 months was 88.5% in participants who completed the entire program (6 times), while 51.3% in participants who did not complete the entire program (${\leq}5$ times) (P=0.001). After adjustment for general and smoking-related characteristics, complete implementation of hospital-based smoking cessation intervention was significantly associated with continuous abstinence from smoking after 12 months (odds ratio: 5.93; 95% confidence interval: 1.45-24.22). Conclusions: The hospital-based smoking cessation intervention might be effective for smoking cessation in patients with cerebral infarction, especially when the intervention was implemented thoroughly.

Background: This study investigates the impact of the cervical musculoskeletal intervention on post-traumatic stress disorder patient's cervical pain levels and depression factor. Methods: Thrty neck pain patients diagnosed with post-traumatic stress disorder were enrolled. Neck exercise training using a sling system was applied to the experimental group and self-neck movement exercise, modification of the McKenzie exercise, was applied to the control group. Both groups were checked every week whether they performed or not. Both groups performed their exercise for 35 minutes for a time and 3 times per week. Total period of the intervention was 6 weeks. To compare the effects of interventions, threshold of cervical tenderness and depression level were measured before and after the each intervention and also measured at follow-up. Results: Painthreshold of left trapezius showed a significant difference between two groups at three points. It increased 19.71% in the experimental group after the intervention compared to before the intervention. At follow-up it also increased 20.06% in the experimental group. Pain threshold of right trapezius showed a significant difference at three points. It increased 18.35% in the experimental group after the intervention compared to before the intervention. At follow-up it also increased 15.93% in the experimental group. According to the result interaction between groups and measurement time in both side of trapezius was valid. Depression level showed significant difference in the experimental group between three points. It decreased 18.07% after the intervention compared to before the intervention and decreased 15.21% at follow-up.

Lignin complexity molecule makes its biodegradation difficult during lignocellulosic wastes composting. So, the improvement of its biodegradation has usually been considered as an objective. This study aimed to determine the impact of Trametes trogii inoculation on organic matter and particularly on lignin and cellulose during green wastes co-composting with olive mill waste water sludge and coffee grounds. Three types of heaps (H1, H2 and H3) were investigated during 180 d. H3 and H2 were inoculated at the beginning of the process (t₀) and 120 d later (t₁₂₀), respectively while H1 was the control. Results showed the absence of pH stabilization in H3 during the first month. Also, in this period we observed a faster degradation of some easily available organic matter in H3 than in the other heaps. After 120 d, a better cellulose decomposition (25.28%) was noticed in H3 than in H1 and H2 (16%). Inoculation during the second fermentation phase induced supplementary lignin degradation in H2 with a percentage of 35% against 23 and 26% for H1 and H3, respectively. For all the runs, a Fourier Transform Infrared analysis showed aliphatic groups' decrease, OH groups' increase and lignin structural modification.

The method of treatment in skeletal Class III malocclusion must be chosen according to an etiology and timing of the treatment. Maxillry protraction has been used as an effective treatment method in growing children with maxillary deficiency. The efficacy of maxillary protraction has been viewed as a result of downward-backward displacement of mandible and compensatory dental displacement during the treatment rather than forward -downward growth of maxilla itself. In this study, 104 subjects treated with maxllary protraction, and 19 males and 21 females with known annual growth amount have been chosen longitudinally as treated group and normal group, respectively. And changes in position of maxilla, mandible and dentition have been comparatively analyzed on the lateral cephalometric radiographs by age. The results were as follows : 1. Treated group showed more forward movement of maxilla compare to the normal group and the mandible displaced backward compare to the normal group. 2. Downward movement of maxilla in treated group was similar to that of normal group with statistical signigicance in female 12 year old group and downward movement of mandible in treated group was similar to that of normal group. 3. In treated group, maxillary central incisor moved more forward than the normal group with statistical significance in male 8, 10 year-old groups and female 8, 9, 10 year-old groups. In treated group, downward movement of maxillary central incisor was similar to that of the normal group with statistical significance in male and female 7,8 year-old groups. Considering the above results and the duration of the treatment, the forward movement of maxilla due to maxillary protraction was effective compared to normal growth amount of the normal group.

Statement of problem. Various anodic oxidation techniques can be applied to dental implant surfaces. But the condition for optimal anodized surfaces has not been described yet. Purpose. The purpose of this investigation was to compare an implant that was oxidized by another method with $TiUnite^{TM}$ through resonance frequency analysis and histomorphometry. Material and methods. Turned (control), $TiUnite^{TM}$ and another oxidized fixtures, which used $Ca^{2+}$ solution for anodic oxidation, were placed in the tibiae of 5 New Zealand White rabbits. The bone responses were evaluated and compared by consecutive resonance frequency analysis once a week for 6 weeks and histomorphometry after a healing period of 6 weeks. Results. At the first week, both oxidized implants showed significantly higher implant stability quotient (ISQ) values than the control. No significant differences in resonance frequency analysis were found between the two oxidized groups for 6 weeks. The means and standard deviations of bone-to-implant contact (BIC) ratios were $71.0{\pm}4.2$ for $TiUnite^{TM}$, $67.5{\pm}10.3$ for the $Ca^{2+}$-based oxidation fixture, $22.8{\pm}6.5$ for the control. Both oxidized implants were significantly superior in osseointegration to the turned one. There was, however, no statistically significant difference between the two oxidized implants. Conclusion. $TiUnite^{TM}$ and the $Ca^{2+}$-based oxidation fixture showed superior early bone response than the control with respect to resonance frequency analysis and histomorphometry. No significant differences between the oxidized groups, however, were found in this investigation using the rabbit tibia model.
