Purpose: Treatment for periodontitis has evolved over the years as new technologies have become available. Currently, lasers seem attractive as a treatment modality, but their effectiveness needs to be verified. The purpose of this project was to evaluate Laser Assisted New Attachment Procedure^® (LANAP^®) surgery as a single treatment modality. Methods: As part of a mandatory training program for periodontists and other dentists, 22 consecutive patients diagnosed with moderate to severe periodontitis (probing depth [PD] up to 11 mm) were treated with the LANAP^® surgical approach using a 1064-nm Nd:YAG laser as part of a multi-step protocol. Following single-session active therapy, they were entered into a maintenance program. Their clinical status was re-evaluated at 12-18 months following surgery. Results: All 22 patients completed the 12- to 18-month follow-up. PD, clinical attachment level, and furcation (FURC) showed substantial improvement. Recession was minimal (mean, 0.1 mm), while 93.5% of PD measurements were 3 mm or less at re-evaluation. Furthermore, 40% of grade 2 FURC closed clinically. Conclusions: Within the limits of this case series, LANAP^® was found to be an effective, minimally invasive, laser surgical therapy for moderate to advanced periodontitis.

Since non-cardiac chest discomfort (NCCD) can result in substantial healthcare burden and lower quality of life, interventions such as cognitive behavioral therapy (CBT) have been investigated for the relief of NCCD. In this review, we aimed to summarize the evidence on the efficacy of the CBT for the treatment of NCCD while introducing a newly-developed computerized CBT program for NCCD. Studies applying CBT to individuals with NCCD were searched for from both English and Korean electronic databases. Among 37 studies, 11 randomized controlled trials, 4 case-control studies, 1 case series, and 2 review articles were eligible for this review. Efficacy of conventional CBT for NCCD was shown in a series of studies as most of them reported improved symptom severity of NCCD or NCCD-related anxiety. However, a substantial variability existed among these studies in participants, treatment procedures and durations. High attrition rates were also reported in these studies on conventional CBT. Computerized CBT could be an alternative to the conventional CBT as it can be standardized and more easily accessible, but it was only reported in one previous study. In addition to the literature review, we presented a newly-developed computerized CBT program for NCCD which may overcome some of the limitations of conventional CBT. A computerized CBT could be an alternative treatment of NCCD, however, need further studies on its usefulness.

Background: The purpose of this study was to investigate the effects of physical therapy intervention with local vibration on the physical function of patients with traumatic patella fractures. Methods: This study recruited 6 subjects who had suffered traumatic patella fractures. The study was conducted for an average of 12.8 weeks. Before the treatment (2 weeks post-surgery), they were evaluated using the numeric pain rating scale (NPRS), the Korean-version of the impact of event scale-revised (IES-R-K), pressure pain threshold (PPT), range of motion (ROM) of the knee joint, and the Korean knee injury and osteoarthritis outcome score (K-KOOS) and were reevaluated after 7 and 12 weeks, post-surgery. This study was conducted according to ORIF Patella Fracture Post-Operative Rehabilitation Protocol after applying local vibration. The protocol consists of Phases 1~5 and this study has been applied from phase 2. Results: A comparison of the performance of the participants before and after the intervention showed a decrease in NPRS (9.83±.41→4.83±.98), IES-R-K (68.67±2.73→23.83±2.40), and K-KOOS (Function, Daily living: 70.5±5.96→34.0±3.35, Function, Sports and Recreational activities: 22.83±2.32→10.77±1.37, Quality of Life: 19.33±7.33→7.33±.52) scores. And the ROM (Knee flexion: 30.0±4.47°→128.73±3.6°, Knee extension: -6.83±2.48°→-1.33±1.03°) and PPT (9.67±.52kg/cm²→22.44±2.33kg/cm²) scores increased. Conclusion: These results show that physical intervention with local vibration using a Blackroll® booster and head can help to improve pain, physical function, and psychological status. Also, it was possible to select interventions depending on the patient's condition and the desired goal, using physical intervention with the Blackroll® booster technique.

Purpose : This case study aimed to investigate the effects of backward walking exercises with a front-loaded bag on craniovertebral angle (CVA), craniorotational angle (CRA), and gait variables in subjects with forward head posture (FHP). Methods : Two individuals in their twenties with FHP performed backward walking exercises on a treadmill while carrying a front-loaded bag with a load equivalent to 20 % of their body weight, for 30 minutes per day, three times a week, over two weeks. CVA and CRA were measured before and after the intervention using side view photographs taken from 1.5 meters away. CVA was calculated by marking C7, the tragus of the ear, and the outer canthus of the eye, and CRA was determined using the same landmarks. Image J software was used for angle analysis, with measurements taken three times and averaged. Gait variables such as step length and cadence were recorded using a step analysis treadmill and analyzed with the software included with the equipment, with measurements taken at baseline and after the two-week intervention. Results : Both participants demonstrated notable improvements in the CVA, indicating enhanced head alignment relative to the cervical spine. There was also a marked decrease in the CRA, suggesting a reduction in rotational misalignment. Although differences were observed in gait variables, such as step length and cadence, these changes were not consistent across measurements. The results suggest that backward walking exercises with a load carried in front can positively influence postural adjustments by aligning the cervical spine in individuals with FHP. Conclusion : The findings of this case study indicate that backward walking exercises with a front-loaded bag can effectively improve cervical spine alignment in individuals with FHP. Differences were observed in gait variables, such as step length and cadence, but these changes were not consistent across measurements. Future studies should explore these effects more comprehensively and consider optimizing the exercise protocol for better therapeutic outcomes.

This paper focuses on the reverse blocking busbar protection scheme with aim to improve the speed of its operation and at the same time to increase operational reliability, flexibility and stability of the protection during external and internal faults by implementation of the extended functionality provided by the IEC61850 standard-based protective Intelligent Electronic Devices (IEDs). The practical implementation of the scheme by the use of IEC 61850 standard communication protocol is investigated. The proposed scheme is designed for a radial type of a distribution network and is modeled and simulated in the DigSILENT software environment for various faults on the busbar and its outgoing feeders. A laboratory test bench is built using three ABB IEDs 670 series that are compliant with the IEC 61850 standard, CMC 356 Omicron test injection device, PC, MOXA switch, and a DC power supplier. Two types of the reverse blocking signals between the IEDs in the test bench are considered: hard wired and Ethernet communication by using IEC 61850 standard GOOSE messages. Comparative experimental study of the operational trip response speeds of the two implementations for various traffic conditions of the communication network shows that the performance of the protection scheme for the case of Ethernet IEC 61850 standard-based communication is better.

Purpose : There are two modalities, those are small bowel series(SBS) and abdominal pelvic computed tomography(CT), for diagnosis of small bowel disease. The aim of this study is to lend radiological technologists who are doing the two modalities assistance in the understanding characteristic of disease by comparing the two results. Meterials and method : 284 patients were examined the two SBS and abdominal pelvic CT together from 1999 to 2003. 250 ml $BaSO_4$ suspension 40 w/v% and 600ml carboxy methyl cellulose 0.5 w/v% were used for SBS. Abdominal Pelvic CT was examined in one hour before taking 450 ml $BaSO_4$ suspension 1.5 w/v%. The CT scan was done in 72 sec after 150 ml contrast media injection. the used protocol was helical mode 5:5 mm pitch 1.375:1, speed 27.50, exposure 120 kv, 240 mA, tube rotation time 0.5 sec. the statistic analysis was conducted with statistical program SPSS 10 version with frequency and crossing analysis. P-value less than 0.05 were considered significant. Results : In the results of SBS, normal findings were 131 patients(46.1%), inflammatory bowel disease(IBD) 64(22.9%), ischemia+ileocolitis+vasculitis 22(7.7%), Obstruction+stricture 21(7.7%) and Others 45(15.9%). In the results of abdominal pelvic CT, normal findings were 103 patients(36.3%), inflammatory bowel disease 65(22.9%), wall thickening+lymphadenopathy 42(14.8%), Fluid collection 17(6%), and Others 57case(20%). The same results of the two were 130patients(45.8%). 30patients(10.6%) of normal finding in SBS were diagnosed as wall thickening+lymphadenopathy and IBD in CT, and 15patients(5.3%) of normal finding in CT were diagnosed as ischemia+ileocolitis+vasculitis, mass and IBD in SBS(p<0.05). Transit time delay was diagnosed in 10patients(3.5%) on only SBS, wall thickening+lymphadenopathy was diagnosed in 20patients(7%) in only CT(p<0.05). Conclusion : We think that proper examination method will be selected in the small bowel disease, if we understand the characteristics of the disease and method.

Objectives : The purpose of this study was to report possibility of acupuncture or moxibustion for the treatment of Parkinson's disease (PD) by reviewing literature about its effectiveness. Methods : In this review, PubMed, SCOPUS, Science Direct and CINAHL of EBSCOhost were used to search medical journals, using keywords "Parkinson's disease and acupuncture" and "Parkinson's disease and moxibustion". The search range included randomized controlled trials (RCT) about Parkinson's disease combined with another disease and other treatments with acupuncture or moxibustion. Non-randomized controlled trial (nRCT), case study, animal experiment, human experiment, review, survey, essay, letter, and protocol for review were excluded. Results : From 311 studies, 111 were selected during the title and the screening. Finally, 16 RCTs (15 for acupuncture research and one for moxibustion) were included in this review, after scanning and matching the inclusion and exclusion criteria. The number of patients varied between 5 and 88. A total of 12 studies using electroacupuncture (EA) were classified into acupuncture studies. The body acupuncture studies numbered 4, scalp acupuncture 4, body and scarp acupuncture mixed studies 4, and bee venom, ear and abdomen acupuncture were each one study. In evaluation methods, total effective rate method was used in 9 studies, the Unified Parkinson's Disease Rating Scale (UPDRS) was used in 8, and the Webster score in 2. In addition, the Berg balance scale (BBS), 30 m walking time, steps to walk 30 m, PD motor function score, and Motor Performance Series by Schoppe (MLS) method were used for evaluation. In 15 of the 16 studies, the verum acupuncture group showed significant improvement compared with the control. In 9 studies using total effective rate method, the effective rate was reported as 80.0-97.3% in verum acupuncture groups and 52.6-86.4% in controls. Conclusions : Acupuncture may be a plausible alternative method to care for the long term symptoms and treat movement impairment of Parkinson's disease. However, to confirm this result, high quality studies including randomized, placebo-controlled double-blind trials are warranted.
