Objectives: The purpose of this study was to investigate the effects of modified fasting therapy on the changes of body compositions. Methods: We analyzed the medical records of 33 patients, who carried out modified fasting therapy at Dunsan Korean Medicine Hospital of Daejeon University from January 1st, 2011 to December 30th, 2015. They went through reducing food intakes period (7 days), fasting period (14 days) and refeeding period (14 days). Body compositions (weight, body mass index, skeletal muscle mass, percent body fat, basal metabolic rate, waist-hip ratio, visceral fat area) were reviewed at each state. And then the data was analyzed. Results: The body composition values (weight, body mass index [BMI], skeletal muscle mass, percent body fat, basal metabolic rate, waist-hip ratio, visceral fat area) decreased during the fasting therapy period, as a whole. The weight, BMI, percent body fat and visceral fat area decreased during the reducing food intakes period, the fasting period and the refeeding period. The skeletal muscle mass and basal metabolic rate significantly decreased during the reducing food intakes period and the fasting period, and insignificantly increased during the refeeding period. Conclusions: Results from this investigation showed that modified fasting therapy using fermented herbal medicine have positive effects on changes of body compositions.

Objective: This study was designed to evaluate the effect of Bee Venom Pharmacopuncture therapy in patients with Cervical Herniated Intervertebral Disc Methods: We investigated 30 cases of patients with Cervical Herniated Intervertebral Disc, who had been treated from October 2008 to December 2011. We divided patients into two groups: Group I was treated by Bee Venom Pharmacopuncture therapy and general acupuncture and Group II was treated by acupuncture therapy only. We measured the efficacy of treatments using the numerical rating scale(NRS). Results: 1. The treatment method for Group I was more effective than that of Group II in reducing the NRS on the tenth day after admission but there was no statistically significant difference between the results of two groups on the fifth day after admission and the tenth day after admission. Conclusion: The results of this study suggest that Bee Venom Pharmacopuncture therapy is effective in reducing pain for patients with Cervical Herniated Intervertebral Disc. Further clinical research is needed to verify these results and findings.

The aims of the present study are firstly to investigate the amount of bone loss around non-submerged implants placed in the posterior region and secondly to investigate the relationship between inter-implant and implant-tooth distance and peri-implant bone loss. Thirty-one subjects with 60 implants were selected consecutively from the implant patient pool at the department of Chonbuk National University Hospital. To be included in the study subject, the implant should have been functioned more than 6 months after loading. Inter-implant and implant-tooth distance, distance between implant shoulder and the first bone contact with the implant(DIB) were measured from the scanning image of the radiograph of each implant. The result showed that; 1. inter-implant distance has a statistically significant relationship with DIB in Pearson correlation analysis. 2. the DIB at the implant facing surface of the implant was greater than that of tooth facing surface of the implant. Within limitation of this study, it is suggested to place an implant not too closely to adjacent implants, and the presence of a tooth adjacent to an implant may keep the level of tooth-facing surface of the implant. Further studies with a prospective design are needed to elucidate the relationship between bone changes and various dimensions around implants.

Perforation of maxillary sinus is a common complication of implant placement in posterior maxilla. The purpose of this study was to evaluate the prognosis of sinus perforated implants placed in partially edentulous maxillae. Eighteen sinus perforated implants in 15 patients were examined for cumulative survival rate, radiographic preoperative bone level, and radiographic marginal bone level change. Twenty-two non-perforated implants in the same patients served as control. The results were as follows; 1. There was no statistically significant difference in cumulative survival rate between sinus perforated implants and non-perforated implants (P>0.05). 2. There was no statistically significant difference in the marginal bone level between sinus perforated implants and non-perforated implants (P>0.05). 3. There was no statistically significant difference in cumulative survival rate according to the preoperative bone level (P>0.05). These results suggests that perforation of maxillary sinus may not affect implant success in posterior maxillae.

Purpose: This study aimed to identify patterns of diagnosis and to explore risk factors for type 2 diabetes beyond the postpartum period in women with a previous history of gestational diabetes, and to identify differences in such risk factors between early and late-onset (aged <45 and ${\geq}45$). Methods: Using epidemiological data from the Korean Genome and Epidemiology Study, a retrospective analysis of 175 women with various timings of type 2 diabetes diagnosis was performed. Results: The average age ($42.6{\pm}10.6$) at type 2 diabetes diagnosis was earlier than the general population, and obesity was prevalent with marked weight gains around 35 years old. Longer duration of breastfeeding was observed in women with late-onset of type 2 diabetes. Conclusion: For prevention of type 2 diabetes, early intervention is required, and modifiable factors such as weight control and breastfeeding should be taken into consideration for intervention strategies.

Unerupted or erupted supernumerary tooth may cause crowding, diastema, cyst formation, resorption, and displacement or rotation of adjacent teeth. However, there are few studies about prognosis about the pathologic condition and expectation of spontaneous eruption. The object of this study is to evaluate factors predicting the spontaneous eruption of supernumerary tooth. 431 patients (346 males and 85 females, aged from 5 to 29 years) who visited our institution from 2002-2006 and were shown to have 471 mesiodentes was reviewed. Supernumerary teeth were classified inverted and not inverted state. In case of not inverted supernumerary tooth, eruption rate ac cording to length of supernumenary tooth, width of the tooth, angle between the tooth and incisor tooth, location (inside the incisor or not) and shape (conical or tubercle) were investigated. The regression model showed that length, width and angle were all important determinants of influencing the eruption of supernumerary tooth (p < 0.001, Pearson R: 0.619). There is no relation between shape and eruption of supernumerary tooth (p > 0.05). Location of mesiodens has an effect on eruption of supernumerary tooth (p < 0.01).

This study investigates the success rate of pulpotomy using electrosurgery operated on a primary molar in caries. The pulpotomy using electrosurgery was done on 253 primary molars of 111 young patients from 2 to 9 years old during the period of the first day of January 2011 to the last day of December 2015. After the amputation of pulp and hemostasis of primary molar were done using electrosurgery, MTA as pulp capping material was applied to the primary molar and the tooth was restored with the stainless steel crown. The follow up period after the treatment ranged from 4-46 months. The clinical and radiographic success rate ranged from 92.1 - 94.3%. Which is comparable to formocresol and ferric sulfate pulpotomy. Due to its non-pharmacological characteristic, electrosurgery can minimize harmful effect on the pulp tissue. Its fast bleeding control makes it easy and safe to use in pediatric and disabled patients in comparatively simple manner. Electrosurgery can be an alternative for pulp therapy considering the side effects of pharmacological ways.

Centrifugal blowers are widely used for air handling units in industry applications. The blower has a centrifugal impeller and a scroll casing including a driving component such as an electric motor. The impeller takes forward or backward blades to induce flows into the blower, Comprehensive investigation according to the two kinds of blades is systematically carried out for a guidance of design for this kind research. It is observed that flow rate of the blower with forward blades is larger than that of the system with backward blades. Otherwise, the system noise is more pronounced in the case of the blower with forward blades. The reason is due to larger velocity from the rotating forward blades that pose obtuse angle with the circumferential direction. The distinguished characteristics are validated by a parallel experiments with a wind tunnel and in an anechoic chamber. Numerical analysis for the system shows detail information inside the blades and the casing. A series of figures to show the flow details offer deep understanding of the performance of a centrifugal blower with different blades.
