Purpose: The purpose of this study was to investigate the relationships between the degree of smart phone addiction among adolescents and their depression and anxiety levels. Method: In this study, 379 high school students were selected using the convenient sampling method. The instruments used for this study were smart phone addiction measure, the CES-D (Center for Epidemiological Studies-Depression Scale), and the STAI (State-Trait Anxiety Inventory). Data were analyzed using the SPSS 20.0 program with descriptive statistics, t-test, ANOVA with Scheffe test, and Pearson’s correlation coefficient. Result: The mean score for smart phone addiction was 40.45±17.27, depression was 36.56±9.58, state anxiety was 44.00±9.61, and trait anxiety was 45.70±9.75. There were significant differences between the degree of smart phone addiction and the following variables: gender (t=-4.953, p<.001), hours of smart phone use per day (F=12.259, p<.001), types of frequently used features (F=3.485, p=.008), and satisfaction level for smart phone (F=5.18, p<.001). There were statistically significant relationships (p<.001) among degree of smart phone addiction, depression level, and state and trait anxiety levels. Conclusion: The results of this study suggested that there was a significant relationship between smart phone addiction and mental health, specifically, depression and anxiety among adolescents. Further research is needed to develop nursing strategies to provide care for adolescents who frequently utilize smart phones.

Objectives: The purpose of this study was to assess the correlation relationship between personal exposure and urinary hippuric acid in biological monitoring for airborne toluene in an industrial complex and in general environments. Methods: Personal exposure to toluene and its metabolite, hippuric acid, in urine were simultaneously measured in occupational environments area near an industrial complex and in general environments. The study subjects were divided into three types: 137 workers who use organic solvents in the workplace, 210 residents living near a dyeing industrial complex, and 379 residents living in general environments. The toluene exposures of workers and residents were measured by a passive sampler for four days. The urine of participants was sampled when the passive samplers of personal exposure were collected. Results: The toluene and hippuric acid concentrations of workers were the highest, followed by the concentrations of residents living near a dyeing industrial complex and residents living in general environments. The coefficient of correlation between the concentrations of toluene and hippuric acid among workers was 0.749 (p<0.01) in the workplace. On the contrary, correlations between the concentrations of toluene and hippuric acid among residents living near a dyeing industrial complex and residents living in general environments were all not significant. The relationship between the concentrations of hippuric acid and toluene in three types could be described by the exponential growth model. Conclusions: This study analyzed the relationships between toluene exposure and the concentrations of hippuric acid in urine in high, middle, and low exposure environments, and could be described by the exponential growth model.

Purpose: This study examined the clinical success rate of Mg titanate implants (M Implant system, Shinhung, Korea), which employ a Mg coating method, by evaluating the marginal bone loss and implant stability using radiographs and Osstell, over a 1 year. Materials and methods: The locations of the implants placement were divided into 4 areas; the maxillary and mandibular premolars and molars. In the maxilla, 8 and 9 implants were inserted in the premolar and molar areas, respectively. In the mandible, 11 and 51 implants were inserted in the premolar and molar areas. Marginal bone loss and ISQ of all implants (79) were measured after insertion, mounting the prosthetic appliance, and 1, 3, 6, and 12 months after loading. The marginal bone loss was measured from the radiograph using XCP bite, which was customized, and the implant stability measured using Osstell. Fisher's exact test (α=.05) was used to compare the success rates of each region. Results: The mean marginal bone loss for the upper and lower jaws were 1.537 mm and 1.172 mm. The mobility showed a non-significant reduction or increase according with time. The success rates were accounted for 94.12% and 98.39% in the upper and lower jaws; the premolars and molars were accounted for 100% and 96.67%. The two cases of early failure resulted from failure of primary stability during implant insertion. The late failures were not observed for 1 year after adding a loading to the implants. Conclusion: The Mg titanate implant showed good primary stability and good clinical results in both healing and function. 연구 목적: 부분 무치악 환자에서 Mg titanate implant (M Implant system, Shinhung, Korea)의 보철후 1년간의 방사선사진을 이용한 변연골 흡수량과 Osstell을 이용한 임플란트 안정성 평가 결과를 분석하여 임상적인 성공률에 대해 알아보고자 한다. 연구 재료 및 방법: 38명의 환자에 79개의 임플란트를 식립하여 보철 후 1년 동안 변연골 흡수량, 임플란트의 동요도, 임플란트 식립 위치에 따른 분포 및 성공률, 보철 전후에 따른 성공률을 분석했다. 결과: 변연골의 흡수량은 보철물 장착 후 1년간의 평가에서 상악에서는 평균 1.537 mm, 하악에서는 평균 1.172 mm의 변연골 흡수가 관찰되었으며, 전체적인 상하악의 평균 변연골 흡수량은 1.255 mm로 관찰되었다. 수술 후 시간이 경과함에 따라 ISQ값은 미약하게 감소하였다가 증가하는 경향을 보였으나, 상악과 하악 모두에서 식립 당일 이후 예비 인상일, 최종 보철물의 장착일과 주기적인 평가 기간 동안 ISQ값의 큰 증가나 감소를 나타내지는 않았다. 성공률은 상악에서의 94.12%였고, 하악에서의 98.39%였다. 결론: 본 실험의 결과로 미루어 Mg titanate implant는 임상적으로 양호한 결과를 보여주었다.

Objective : Because the cause and etiology of chronic headache are not yet fully explained, the treatment of this symptom is not simple. In order to study the effectiveness East-West pain treatment on chronic headache, we evaluated its effect of pain alleviation and quality of life improvement on chronic headache patients who were treated with nerve block and acupuncture, and only acupuncture for eight weeks. Methods : 92 clinical experiment participants were gathered and through a questionnaire patients who experienced headache for more than 4 hours a day and more than 15 days per month were qualified as chronic headache patients. The qualified patients were classified into two groups, nerve block and acupuncture group(EW group, n=49) and acupuncture group(E group, n=43). Treatment was applied 2 times a weeks for 8 weeks. The acupoints, GV20, HN23, ST8, HN46, TE17, GB20, LI20, LI11, LI14, ST36, and LR3 were stimulated for 20 minutes. The effects of two groups were analyzed using VAS scores and BPI(Brief Pain Inventory). Results : The VAS and BPI after four weeks of treatment showed significant improvement among two but differences between the three groups was statistically insignificant. The VAS and BPI of the EW group after eight weeks of treatment showed statistically significant improvement compared to the other two groups. Conclusion : The pain treatment for chronic headache might be contributed to improvement of quality of life as well as alleviation of pain of chronic headache patients. It was suggested that the West pain treatment in combination with East pain treatment might be an useful modality to improve the pain and quality of life in chronic headache patients.

Objective : The purpose of this study was to assess the effect of acupuncture treatment for chronic headache patients using power spectrum analysis of the heart rate variability(HRV). Methods : 15 clinical experiment participants were gathered and through a questionnaire patients who experienced headache for more than 4 hours a day and more than 15 days per month were qualified as Chronic Headache patients. Treatment was applied 2 times a weeks for 8 weeks. The acupoints, GV20, HN23, ST8, HN46, TE17, GB20, LI20, LI11, LI14, ST36, and LR3 were stimulated for 20 minutes. The effects of acupuncture treatment were analyzed using power spectrum analysis of the HRV, HRV was recorded before and after acupuncture treatment. Results : HRV before and after treatment was compared after 8 weeks of acupuncture treatment. Increase in mean values of SDNN and RMSSD were observed but the increases were not statistically significants. Increase in mean values of TP, LF and HF were observed but, the increase was significant(p<0.05) only in TP. Conclusions : The results suggest that acupuncture treatment on chronic headache patients can increase the activity of autonomic nervous system. Further use of HRV for quantitative analysis of acupuncture treatment on autonomic nervous system related symptoms is suggested.

Background : Studies on cytomegalovirus (CMV) diseases in Korean hematopoietic stem cell transplant (HSCT) recipients are lacking and do not reflect the recent trends of advances and changes. Therefore, we tried to analyze the clinical features of CMV diseases in HSCT recipients over the past 10 years at a tertiary university hospital in Korea. Methods : Retrospective review of medical records was done for all adult HSCT patients who received transplant at the Catholic HSCT Center from January 1998 to January 2008. Results : Forty-four cases (2.2%) of CMV diseases were identified. CMV pneumonia was diagnosed in 17 patients, retinitis in 16 patients, enterocolitis in 7 patients, esophagitis 1 patient, gastritis in 1 patient, duodenitis in 1 patient, and hepatitis in 1 patient. The median onset of symptom was 90 days after transplantation. Late CMV diseases accounted for 47.7%. CMV related death varied from 0 to 58.8% according to the involved organ. CMV retinitis was diagnosed relatively later in the course of transplantation mostly in patients who had chronic graft versus host disease (GVHD). On the contrary, CMV enterocolitis mainly occurred in patients who suffered from acute GVHD. The overall concurrent CMV reactivation was documented to be 63.6%: the concurrent CMV reactivation was observed only in 37.5% of patients with retinitis. Conclusions : We observed some differences in the pattern of CMV disease manifestation according to the involved organ and reconfirmed the fact that CMV pneumonia is the most common and fatal disease in HSCT recipients. Additionally, CMV retinitis was not uncommon in HSCT recipients. Since specific marker does not exist in predicting retinitis, regular ocular examination should be done thoroughly, especially in patients with chronic GVHD.
