This study has comparatively analyzed the primary success factors in smoking cessation among new enrollees and re-enrollees of a smoking cessation clinic in order to find out how to efficiently operate smoking cessation clinics at public health centers. The study was conducted with 262,837 smokers aged 19 or over who were provided with smoking cessation services for more than 6 months after being registered with the smoking cessation clinic at public health centers(250 clinics nationwide) from July 16, 2006 to July 15, 2007. After dividing smokers into re-enrollees and new enrollees of the smoking cessation clinic, the success rate of and success factors for smoking cessation over 6 months have been investigated. The success factors in smoking cessation have been compared between new enrollees and re-enrollees of smoking cessation clinics. The results can be summarized as follows: First, the success rate of smoking cessation for 6 months at smoking cessation clinics of public health centers was higher in new enrollees (46.3%) than in re-enrollees (41.1%). Second, the common factors that had an influence on the success of smoking cessation of both new enrollees and re-enrollees of the smoking cessation clinic included age, social security, service, frequency of counseling, number of cigarettes per day, and alcoholic problems. Third, compared to new enrollees, re-enrollees had a higher success rate of smoking cessation as they got older. In terms of the success rate of health insurance, on the contrary, new enrollees were better than re-enrollees. Fourth, the study showed a higher success rate in smoking cessation in both new and re-enrollees if they had no alcoholic problems. In particular, a higher success rate was observed in re-enrollees when there were no alcoholic problems. To efficiently operate smoking cessation clinics at public health centers, this study confirmed that counseling should be tailored depending on the types of enrollees in the program.

Objectives: This study has longitudinally analyzed male smokers in order to find out the trend rate of re-smoking after smoking cessation. Methods: The study was conducted with 800 male smokers who were provided with smoking cessation services for 3 years at public health centers from July 16, 2005 to July 15, 2008. Results: The results can be summarized as follows: First, the success rate of smoking cessation for at least 6 months during 3-year period was 54.4%. The failure rate of smoking cessation at the second year was 47.5% and the third 27.2%, which indicates that the failure rate diminishes as the period of smoking cessation extends. Second, the success rate of smoking cessation at the first trial was 35.0%, the second 24.3%, and the third 16.4%. The success rate diminished as the number of trial increased. Third, the continuation rate of smoking cessation for a year was 18.3%, for 2 years 13.4%. For the success group, the continuation rate of smoking cessation for a year was 52.5%, for 2 years 38.2%. For the failure group, the rate for a year was 21.5%. Fourth, in this longitudinal analysis, the most crucial variables that affect the success rate of smoking cessation are total number of consultation and the past experience of successful smoking cessation. Conclusion: This study shows that success of smoking cessation and the continuance of smoking cessation are both difficult, and that the past experience of smoking cessation plays an important role determining the present success of smoking cessation and continuance of smoking cessation. Thus, it is necessary to divide people into success group and failure group based on the results of the past experience of smoking cessation when they consult at smoking cessation clinics at public health centers. Further, in order to increase the continuation rate of smoking cessation, this study suggests that we need to consider ways to take care of those who successfully abstained from smoking for 6 months.

This study investigates the improvement in the theoretical success rate of the integer ambiguity resolution in GPS/GNSS carrier-phase positioning by using many visible satellites. It estimates the dependence of the rate on the baseline length in relative positioning under the condition of the use of double/triple-frequency navigation signals. The calculation results show that the use of 14 navigation satellites (i.e., seven GPS and seven Galileo ones) remarkably improves the success rate under the condition of very short baseline length, compared with the use of seven GPS ones. The numerical reliability of the calculated success rates is strictly tested by examining the tightness of the union and minimum-distance bounds to the rate. These bounds are also shown to be effective to investigate the realization of the high success rates.

Purpose : The purpose of this study was to determine the changes that occur due to the real-time monitoring of paddle pressures which has an important influence on the defibrillation success rate in defibrillation treatment known as the only treatment for cardiac arrest patients with VF. Methods : 40 people participated in the cardiac arrest simulation training and played the role of the defibrillation operator. Investigators measured the pressure of paddle while defibrillating by using instrument which was developed by the investigator. Results : Through real-time monitoring of the paddle pressures of defibrillator by indicator, the front sternum paddle showed a 77.5% success rate and the apex paddle showed a 40% success rate. While the values without monitoring the paddle pressures, the front sternum paddle showed a 51% success rate and the apex paddle showed a 20% success rate. These experiment revealed statistically significant(p <.001) low success rate. Conclusion : The method of monitoring the paddle pressures during defibrillation showed that the paddle can be precisely gripped. The success rate of paddle pressures is significantly correlated with height, weight and grip strength.

Objective: The purpose of this study was to investigate factors influencing the success rate of orthodontic microimplants (OMIs) using panoramic radiographs (PRs). Methods: We examined 160 OMIs inserted bilaterally in the maxillary buccal alveolar bone between the second premolars and first molars of 80 patients (51 women, 29 men; mean age, $18.0{\pm}6.1years$) undergoing treatment for malocclusion. The angulation and position of OMIs, as well as other parameters, were measured on PRs. The correlation between each measurement and the OMI success rate was then evaluated. Results: The overall success rate was 85.0% (136/160). Age was found to be a significant predictor of implant success (p < 0.05), while sex, side of placement, extraction, and position of the OMI tip were not significant predictors (p > 0.05). The highest success rate was observed for OMIs with tips positioned on the interradicular midline (IRML; central position). Univariate analyses revealed that the OMI success rate significantly increased with an increase in the OMI length and placement height of OMI (p = 0.001). However, in simultaneous analyses, only length remained significant (p = 0.027). Root proximity, distance between the OMI tip and IRML, interradicular distance, alveolar crest width, distance between the OMI head and IRML, and placement angle were not factors for success. Correlations between the placement angle and all other measurements except root proximity were statistically significant (p < 0.05). Conclusions: Our findings suggest that OMIs positioned more apically with a lesser angulation, as observed on PRs, exhibit high success rates.

We have performed a prospective study to assess the efficacy of suction drainage in 45 patients with primary spontaneous pneumothorax and 15 patients with secondary spontaneous pneumothorax, treated by closed chest tube drainage with underwater seal during the period Jan. 1990 to Dec. 1990 at the Department of Thoracic and Cardiovascular Surgery, Yeungnam University Hospital. The patients were divided randomly into two groups, 28 cases receiving suction and the other 32 cases no suction. The success rate was 82.1% for the former and 87.5% for the latter with the overall success rate of 85.0% and there was no significant difference in success rate between the two groups According to the causes and the extent of pneumothorax, the difference between the success rates of the two groups was also not significant statistically. But according to the duration of air leakage, suction group under 2 days showed a high success rate[46.4%] and the same group with 3-4 days, a relatively low success rate[21.4%] compared with that of the former. We conclude that the suction treatment is somewhat valuable in shortening the tubing time in patients with small amounts of air leakage, but it doesn`t seem to increase the success rate in all patients.

The purpose of this study was to find related factors to success of smoking-cessation in according to general characteristic, smoking, smoking-cessation and mediation factors in participants of smoking-cessation clinic on public health center in Daejeon metropolitan city. We analyzed 2,125 participants registered in smoking-cessation clinic in 2007. We carried out frequency analysis to understand character of participants, $X^2$-test to verify significance between smoking-cessation success rate and character, and logistic regression analysis to understand significance between smoking-cessation success rate and each character. The smoking-cessation success rate during 6 month was 39.8%. In group of smoking-cessation success, male had higher success rate than female. And over 65 years old group had higher success rate than under 40 years old group. Jung gu public health center had higher success rate than other centers. Logistic regression analysis of the factor associated with smoking-cessation success rate showed statistical significance of age, public health center, 2 stage nicotine patch, total consultation times with smoking-cessation success rate. Total consultation times showed highest odd ratios than other significant factors. Therefore, we suggested that total consultation times has most significance with smoking-cessation success rate, and the consultation may be the most effective method in smoking-cessation clinic.

Purpose: The purpose of this study is to predict a reasonable direction to design a pertinent educational program in the future by evaluating an adult CPR(Cardiopulmonary Resuscitation) skill performed by EMTs engaged in fire services organization and comparing the CPR success rate of factors as like a duty place and licensed year. Methods: We studied CPR skill by the use of a CPR manikin(Skillmeter Resusci Annie, Laerdal company). The study population consisted of 320 EMTs. Every EMT performed four cycle after investigating the manikin for 2 minutes. We regarded chest compression with 100 times in a minute as the 100% success rate. We analysed the skill of chest compression, ventilation and chest compression times success rate by the records printed in the CPR paper. Results: The average success rate of chest compression was 59.42$\pm$29.26% and ventilation 49.22$\pm$29.65%. The success rate of manual CPR was different between chest compression and ventilation. Also the success rate of chest compression times was high relatively as a 87.32$\pm$9.14%(p=0.000). For the CPR skill, ventilation was lowest as 49.22%. The factors such as duty place and licensed year did not influence the CPR success rate (p>0.001). Conclusion: We could have conclusion that CPR training should be shared more time in ventilation than in chest compression. Also we could reach to a conclusion that it is important to increase the times of CPR training for improving the accuracy of CPR and that the continuing education of CPR training frequency might be more than four times in a year.

Purpose: Many clinical studies have reported that higher success rates are achieved with teeth that have immature roots than other autotransplanted teeth that have more immature root. However, based on date published recently, the success rate of autotransplantation of teeth with complete root formation was higher. The purpose of this study was to examine the long term(2 to 6 years follow-up) success rate of autotransplantation of third molar with complete root formation and to discuss some conditions and prerequisites for success. Materials and Methods: 26 sites of 24 patients aged 26 to 55 (mean age 40.8) were autotransplanted with third molars with complete root formation. These cases were followed for 2 to 6 years after surgery. The success criteria included (1) no discomfort during functioning (2) absence of progressive root resorption and alveolar bone resorption. Result: Of 26 teeth 5 teeth were failed, therefore success rate is 81%(21/26 teeth). The results suggested that higher success rate is acquired from (1) extraction socket due to dental caries (2) mandibular recipient site (3) patient younger than 40 years old. Autotransplantation of third molar to replace molars with advanced periodontal disease also showed considerably high success rate(84%). Conclusion: With appropriate case selection, autotransplantation of third molar with complete root formation remains a viable alternative for replacing a missing molar tooth.

Background: Advantages of paramedian approach over midline approach include less tissue trauma and less dependence on patient's ability to assume a fetal position. When midline approach fails in patients who are difficult to take a position with lumbar spine flexed, paramedian approach to interlaminar space may succeed. Methods: Success rates of spinal anesthesia were measured for 47 flexed patients by midline approach, 48 flexed patients by paramedian approach, 23 straightened patients receiving spinal anesthesia by midline approach, and 23 straightened patients by paramedian approach. Results: Success rates in flexed patients were 100% by midline approach and 100% by paramedian approach. Success rates for straightened patients were 13.0% by midline approach and 78.3% by paramedian approach. For straightened patients there were no correlations between success fate and age, weight, Ponderal Index but there were correlations between height and midline approach of spinal anesthesia. Conclusion: Pertaining to adult Koreans, success rates of spinal anesthesia for strainghtened patients were less than those for flexed patients. Success rate of paramedian approach of spinal anesthesia among strainghtened patients were better than those of midline approach.
