  • Purpose: The aim of this retrospective study was to determine the prevalence of early implant failure using a single implant system and to identify the factors contributing to early implant failure. Methods: Patients who received implant treatment with a single implant system ($Luna^{(R)}$, Shinhung, Seoul, Korea) at Dankook University Dental Hospital from 2015 to 2017 were enrolled. The following data were collected for analysis: sex and age of the patient, seniority of the surgeon, diameter and length of the implant, position in the dental arch, access approach for sinus-floor elevation, and type of guided bone regeneration (GBR) procedure. The effect of each predictor was evaluated using the crude hazard ratio and the adjusted hazard ratio (aHR) in univariate and multivariate Cox regression analyses, respectively. Results: This study analyzed 1,031 implants in 409 patients, who comprised 169 females and 240 males with a median age of 54 years (interquartile range [IQR], 47-61 years) and were followed up for a median of 7.2 months (IQR, 5.6-9.9 months) after implant placement. Thirty-five implants were removed prior to final prosthesis delivery, and the cumulative survival rate in the early phase at the implant level was 95.6%. Multivariate regression analysis revealed that seniority of the surgeon (residents: aHR=2.86; 95% confidence interval [CI], 1.37-5.94) and the jaw in which the implant was placed (mandible: aHR=2.31; 95% CI, 1.12-4.76) exerted statistically significant effects on early implant failure after adjusting for sex, age, dimensions of the implant, and type of GBR procedure (preoperative and/or simultaneous) (P<0.05). Conclusions: Prospective studies are warranted to further elucidate the factors contributing to early implant failure. In the meantime, surgeons should receive appropriate training and carefully select the bone bed in order to minimize the risk of early implant failure.

  • Background: We investigated the risk of cancer mortality according to obesity status and metabolic health status using sampled cohort data from the National Health Insurance system. Materials and Methods: Data on body mass index and fasting blood glucose in the sampled cohort database (n=363,881) were used to estimate risk of cancer mortality. Data were analyzed using a Cox proportional hazard model (Model 1 was adjusted for age, sex, systolic blood pressure, diastolic blood pressure, total cholesterol level and urinary protein; Model 2 was adjusted for Model 1 plus smoking status, alcohol intake and physical activity). Results: According to the obesity status, the mean hazard ratios were 0.82 [95% confidence interval (CI), 0.75-0.89] and 0.79 (95% CI, 0.72-0.85) for the overweight and obese groups, respectively, compared with the normal weight group. According to the metabolic health status, the mean hazard ratio was 1.26 (95% CI, 1.14-1.40) for the metabolically unhealthy group compared with the metabolically healthy group. The interaction between obesity status and metabolic health status on the risk of cancer mortality was not statistically significant (p=0.31). Conclusions: We found that the risk of cancer mortality decreased according to the obesity status and increased according to the metabolic health status. Given the rise in the rate of metabolic dysfunction, the mortality from cancer is also likely to rise. Treatment strategies targeting metabolic dysfunction may lead to reductions in the risk of death from cancer.

  • Background: Thyroid tumors are generally regarded as rare malignancies. Nowadays, however, their global incidence is growing continuously partially due to western life style and utilization of more sensitive methods of early detection. It is approximately three times more prevalent in females than in males. Most cases of thyroid cancer are asymptomatic nodules or just have local cervical symptoms or adenopathy in early stages. Materials and Methods: The Global Burden of Diseases report 2010 study (released 3/2013) profited from 100 collaborators worldwide and used a vast network of data on health outcomes, vital registries, and population surveys. It shared many of the Global Burden of Diseases 1990 principal databases such as all available data on injuries, diseases, risk factors, as well as comparable metrics, and used different scientific approved methods to estimate important health status data like: death rate, life expectancy, healthy adjusted life expectancy, disability-adjusted life years (DALY), years of living lost due to premature death and years of life with disabilities. Results: DALY as thyroid cancer burden per 100,000 Iranian populations had increased by about 14% during 1990 to 2010 in all ages; from 6.1 (95% UI 4.2-9.74) years in 1990 to 6.95 (95% UI 5.06-9.18) years in 2010 in both sex. The 2010 peak age-group was estimated at 45-49 years in males and 40-45 years in females.

  • Objectives: This study investigated the relationship between obesity and dental caries of Korean adolescents. Methods: Data from the Korea National Health and Nutrition Examination Survey (KNHNES VI) (2013 to 2015) were used and targeted adolescents aged 13 to 18 years. For statistical analysis, the SPSS 18.0 program was used, and the significance level was set at 0.05. Results: For the general and health-related characteristics, female students (p=0.001) showed higher decayed, missing, and filled teeth (DMFT) index than male students. Furthermore, DMFT showed higher tendency, as age was higher (p<0.001). Smoking (p=0.011) and drinking experience (p=0.027) revealed higher DMFT. The dental caries experience was significantly different among students who were female (p=0.033), older (p=0.001), and overweight or underweight (p=0.022). In the BMI for the general and health-related characteristics, male students had higher obesity rate than female students (p=0.003), and obese subjects had higher dental checkup in the last year (p=0.013). In multiple linear regression analysis of obesity and DMFT, the unadjusted model showed that the obesity group's DMFT was about 0.8 higher than that of the normal group (p=0.024). However, statistical significance was not shown in the adjusted models. In the logistic regression analysis of obesity and dental caries experience, the unadjusted model 1 (1.93 times), the adjusted model 2 (1.79 times), and model 3 (1.76 times) showed significantly higher dental caries experience. Conclusions: Both obesity and dental caries are related to diet habits and lifestyles and have a negative impact on adult health. Therefore, it is necessary to create a healthy social environment around the adolescent, and proper intervention through education is required to form healthy habits.

  • Background: Health-care providers typically undergo shift work and are subjected to increased stress. Night shift work may induce disturbed sleep cycles and circadian rhythm. The objective of this study was to explore if night shift workers (NSWs) show an increased risk of abnormal thyroid-stimulating hormone (TSH). Methods: We conducted a retrospective cohort study of 574 employees without thyroid disease and abnormal TSH at baseline who underwent annual check-ups between 2007 and 2016 in a medical center. NSWs were defined as those with working time schedules other than daytime hours. We calculated the incidence rate and estimated the adjusted hazard ratio (HR) for incident abnormal TSH and subclinical hypothyroidism compared with non-NSWs using a Cox regression model. Results: A total of 56 incident abnormal TSH cases and 39 subclinical hypothyroidism cases in NSWs were identified during 3000 person-years of follow-up. In models adjusted for age, sex, obesity, and working departments, we found no increased relative risk for incident abnormal TSH (HR: 0.72, 95% confidence interval: 0.33-1.60) or subclinical hypothyroidism (HR: 0.52, 95% confidence interval: 0.19-1.45) when comparing NSWs to non-NSWs; nor were incidence rates significantly different among exclusively medical employees after excluding administrative staff. Conclusion: In this hospital-based nine-year follow-up retrospective cohort study, NSWs were not associated with increased relative risk of incident abnormal TSH and subclinical hypothyroidism, in contrast to previous cross-sectional studies.

  • Disability-adjusted life-year (DALY) estimates may vary according to factors such as the standard life expectancy, age weighting, time preference and discount rate, calculation of disability weights, and selection of the estimation method. DALY estimation methods are divided into the following 3 approaches: the incidence-based approach, the pure prevalence-based approach, and the hybrid approach. These 3 DALY estimation approaches each reflect different perspectives on the burden of disease using unique characteristics, based on which the selection of a suitable approach may vary by the purpose of the study. The Global Burden of Disease studies, which previously estimated DALYs using the incidence-based approach, switched to using the hybrid approach in 2010, while the National Burden of Disease studies in Korea still mainly apply the incidence-based approach. In order to increase comparability with other international burden of disease studies, more DALY studies using the prevalence-based approach need to be conducted in Korea. However, with the limitations of the hybrid approach in mind, it is necessary to conduct more research using a disease classification system suitable for Korea. Furthermore, more detailed and valid data sources should be established before conducting studies using a broader variety of DALY estimation approaches. This review study will help researchers on burden of disease use an appropriate DALY estimation approach and will contribute to enhancing researchers' ability to critically interpret burden of disease studies.

  • Background: Control of postoperative pain is an important aspect of postoperative patient management. Among the methods of postoperative pain control, patient-controlled analgesia (PCA) has been the most commonly used. This study tested the convenience and safety of a PCA method in which the dose adjusted according to time. Methods: This study included 100 patients who had previously undergone orthognathic surgery, discectomy, or total hip arthroplasty, and wished to control their postoperative pain through PCA. In the test group (n = 50), the rate of infusion was changed over time, while in the control group (n = 50), drugs were administered at a fixed rate. Patients' pain scores on the visual analogue scale, number of rescue analgesic infusions, side effects, and patients' satisfaction with analgesia were compared between the two groups. Results: The patients and controls were matched for age, gender, height, weight, and body mass index. No significant difference in the mount of drug administered was found between the test and control groups at 0-24 h after the operation; however, a significant difference was observed at 24-48 h after the operation between the two groups. No difference was found in the postoperative pain score, number of side effects, and patient satisfaction between the two groups. Conclusions: Patient-controlled anesthesia administered at changing rates of infusion has similar numbers of side effects as infusion performed at a fixed rate; however, the former allows for efficient and safe management of postoperative pain even in small doses.

  • IndustrialiBation and urbanisation have been known to increase divorce rates through the enhancement of emotional function of flmily, the weakness of extendedfamilial network, the separation of public and private spheres, increase of educationallevel for women, increase of labor participation rate for women, and the pursuit ofegalitarian relationship for the couple. Divorce rates by sex, age, province andeducation in Korea for the period 1970 ~ 1995 were examined using the data ofmarriage and divorce registration and population census. Crude divorce rates, sex-age-specific divorce rates and sex-age-adjusted divorce rates were calculated for thetotal population and the married population respectively, and the characteristics ofvarious divorce indicators were discussed. During 1970~1995, divorce rates increasedthree times, and divorce rate in 1995 was 3.5 per 1,000 married persons. Divorcerate was highest for those under 25 years old, and it was increasing rapidly fDr allages, with the most rapid increase fDr the middle-aged. The relative divorce increaserate was highest fDr females than males. Divorce rates were highest for Seoul, Pusan,Inchon, Taejon, Kyonggi, and Jeju, and for aged 25 ~ 34 years of Chonbuk andKangwon. Divorce rate was highest fDr the male elementary-school graduates andlowest for the male college graduates, it was highest for the female high-schoolgraduates and lowest for the female uneducated.

  • Exercises are achievement oriented, the process is frequently perceived as hard and difficult Participants drop out from exercise programs in the middle of the training period. Dance movement, which is the deliberate and systematic use of movement, is enjoyable during the movement and provides opportunities for persons to express them-selves. Regular long term dance movement may in-duce a training effect with a decreased drop out rate. Dance movement could be one way to attain wellness, however, there have been few studies to evaluate both physiological and psychological aspects of dance movement. This study focused on evaluating the effects of dance movement training on body weight, resting blood pressure and heart rate, limb circumference and strength, stress response and subjective feelings. This quasi-experimental study was designed as a nonequivalent control group pre test -post test study. Ten healthy fe-male subjects, aged between 19 and 31 years volunteered for an eight week dance movement program. Ten healthy female subjects, between 19 and 21 years of age paticipated as controls. None of the subjects had performed regular physical activity for six months prior to the study. Dance movement was created with reference to Heber's movement guide. The Dance movement program consisted of approximately 30 minutes of dance, three days per week, for eight weeks. During each 30 minute work out, there were approximately 5 minutes of warm-up dancing, 20 minutes of conditioning dance and 5 minutes of cool-down dancing. The intensity for the conditioning phase was at between 60% and 65% of age-adjusted maximum heart rates. Body weight, resting blood pressure and heart rate, circumference of mid upper arm, mid thigh and mid calf, muscle strength of upper and lower limb, physical and psychological response to stress were measured prior to, and following the experimental treatment. Body weight was measured by digital weight scale(Kyung In Corp., Korea). Resting systolic and diastolic blood pressure were measured by sphygmomanometer, Resting heart rate was measured for one minute in a relaxed sitting position using the radial artery. Circumference of mid upper arm, mid thigh and mid calf was determined by tape measure. Muscle strength of the upper extremities was measured by a grip dynamometer (Takei Corp. No.1857, Japan) and that of the extremities was measured by the length of time the leg could be held at 45° Physical and psychological responses to stress were measured using the Symptoms of Stress (SOS)Scale. Paticipants in the dance movement were interviewed by the facilitator following the eight weeks, and their thematic responses about the dance movement were recorded. Following the eight week dance movement train-ing, body weight decreased significantly, circumference of mid thigh and mid calf increased. The length of time leg - raising could be held tended to increase following the dance movement training. Resting systolic and resting heart rate showed a tendency to decrease. Total mean score of stress response tended to de-crease, and mean score of habitual patterns, do-pression, anxiety / fear, anger and cognitive disorganization decreased remarkably following the eight week dance movement. Thematic responses about the dance movement were positive following the training.

  • To estimate the incidence of uterine cervix cancer among Korean women, we have conducted a study using the claim data on the beneficiaries of Korea Medical Insurance Corporation (KMIC). All medical records of the potential cases with diagnosis of ICD-9 180, 181, 182, 199, 219, 233 in the claims sent by medical care institutions in the whole country to the KMIC from January 1988 to December 1989, were abstracted and Gynecology specialist reviewed the records to identify the new cases of uterine cervix cancer among the potential cases during the corresponding period. Using these data, the incidence of uterine cervix cancer among Korean women was estimated as of July 1, 1988 to June 30, 1989. The crude rate was estimated to be 17.34(95% CI: $16.76\sim17.92$) per 100,000 and the cumulative rates for the ages $0\sim64\;and\;0\sim74$ were 1.7% and 2.2%, respectively. The age-adjusted rate for the world population was 19.93 per 100,000 which was higher than those of other Asian countries including China and Japan in $1983\sim1987$. The truncated rate for ages $35\sim64$ was 52.05 per 100,000 which was one of the highest in the world. With increasing age, the incidence rate increased to 78.11 per 100,000 in women aged $55\sim59$ years, then it decreased in the older groups. This finding suggests that detecting rate of uterine cervix cancer may decrease in women aged 60 years or older due to inadequate medical care seeking behavior. In the geographical area, the SIR of Jeju province was significantly low but it might be due to statistical unstability by small case numbers.
