communicable diseases. The purposes of the study is to estimate reporting proportion of National Notifiable Infectious Diseases(NNIDs) and investigate characteristics related to reporting using KAP(knowledge, attitude, practice) model. METHOD: We surveyed randomly selected 2,185 physicians (speciality: internal medicine, family medicine, pediatrics, dermatology, general physicians) of their knowledge, attitude, and practice of NNIDs reporting through self-administered mail questionnaires. Of them, 231 physicians responded (response proportion: 10.6%). RESULT: The reporting proportion was estimated to 27.0%. Recognition level (knowledge) of NNIDs was relatively high with proportion of 69.4%, and attitude (public health importance) of reporting was 65.8%. Multiple logistic regression analysis showed that knowledge, attitude significantly affected physicians' reporting in a positive direction (O.R. 6.2, 6.2 respectively). Whereas, senior age group, specialty (family medicine, pediatrics, dermatology) showed significantly lower reporting. General (tertiary care) hospital level of care showed significantly higher reporting practice (alpha=0.05). CONCLUSION: The NNIDs reporting proportion, 27.0% is similar with those studied recently. Continuous efforts to increase the performance level of communicable diseases surveillance system. Of those, restructuring surveillance systems considering characteristics of notifiable diseases classes must be stressed. Educational approach of physicians needs to be tailored specially to newly-designated diseases such as Group II, Designated Group NNIDs.

Purpose: This study investigated the prevalence and perceptions of workplace violence against registered nurses (RNs) in hospitals. Methods: One thousand RNs replied to a nationwide survey from November 14 to December 22, 2022. They reported their general characteristics, prevalence of and their responses to different types of workplace violence from patients, family caregivers, physicians, and nurse peers, as well as their perceptions of workplace violence management systems. Results: A total of 71.1% of the RNs reported that they had experienced workplace violence in the last six months. The violence and sexual harassment experienced from patients and family caregivers were 57.3% and 19.1%, respectively. Furthermore, violence, sexual harassment, and workplace harassment from physicians were experienced by 24.6%, 4.0%, and 7.4%, respectively, of the RNs, and those from nurse peers by 21.4%, 3.1%, and 11.3%, respectively. The RNs stated that they often responded to workplace violence with passive and inactive behaviors, which were more serious toward physicians’ workplace violence or sexual harassment from different perpetrators. Only 69.5% were aware of their hospital’s workplace violence management systems, while only 14.7%~27.4%, according to the type of hospital (p=.471), perceived the systems as effective. Multiple important strategies were identified to prevent workplace violence. Conclusion Critical suggestions are discussed for the prevention of workplace violence, including protecting the human rights of healthcare professionals, inter-organizational collaboration, and a culture of person-centered healthcare, and training nurse managers’ competency in managing workplace violence.

Purpose: Although concern about the health disorders in aging men have been growing, the association has not been elucidated in relation to the late onset male hypogonadism(LOH) and metabolic syndrome(MS). In this background, we evaluated the clinical impact of MS on LOH symptoms and serum total testosterone level. Materials and Methods: 100 patients with LOH symptoms who visited to the urology clinic between May, 2004 and October, 2006 were analyzed. Of all object, 48 patients were associated with MS(Group I) and 52 patients were not(Group II), based on the NCEP-ATP III(2001) guidelines. We compared the LOH status with Saint Louis University Androgen Deficiency in Aging Males(ADAM) questionnaire, serum total testosterone level, as well as prevalence of MS components between the two groups. Results: The overall prevalence of MS was 48% among LOH patients. The average age of group I and II were 57.7+/-10.5 and 58.6+/-11.2 years, respectively. Positivity for ADAM questionnaire was 83.3% in group I and 76.9% in group II, respectively(p<0.05). Serum total testosterone level decreased according to number of components of MS(p<0.05). The obesity group had significantly decreased serum total testosterone level(3.41+/-1.34 ng/ml) comparing to control group(4.41+/-2.23 ng/ml)(p<0.05). Conclusions: MS and its risk factors were significantly associated with LOH symptoms and positively correlated with the severity of disease. The evaluation of MS are required for the diagnosis and treatment of the patients with LOH.

This study was conducted among the university students to investigate the effects of working in an daytime and studying in an evening class on dietary behaviors and nutrient intakes. A 24-hour recall method was used along with food frequency questionnaires. The subjects were composed of three groups : 172 were in the daytime calss regular student group(RS), 178 were evening class students without a job(ESWOJ), and 140 were evening class students with a job(ESWJ). An average age of the ESWJ was 31 years old, which was 9 years older than the RS and 7 years older than the ESWOJ. The types of the residence were significantly different among the groups ; were seif-boarding 74% of the ESWJ stayed at home while 47% of the RS were self-boarding and 61% of the ESWOJ. The survey shows that while a great majority of the RS and ESWOJ has breakfast and supper at home, about 10% and 17% of the ESWJ ate breakfast and supper, respectively, at the cafeteria in their work place. The most frequently skipped meal was the breakfast in all groups. Approximately 9% of the ESWJ tended to skip the breakfast, while 27% of the RS and 33% of the ESWOJ did. It turns out that the mose common reason why ESWJ skipped meals was due to a lack of time. About 71% of the ESWJ ate out more than once a week compared to 57% and 62% of the RS and ESWOJ, respectively. Approximately 30% of the ESWJ ate out more than once a week compared to 57% and 62% of the RS and ESWOJ, respectively. Approximately 30% of the ESWJ spent less than 10 minutes at meal time, showing a hurried eating habit. The results show that the ESWJ tended to eat a variety of food s and eat less instant foods, but drink coffee more often compared to the other two groups. The results also show that in all groups, the intakes of energy, Ca, and vitamin A were lower than the Korean Recommended Daily Allowances(RDA). In addition to these nutrients, protein, vitamin B1, vitamin B2, and niacin were also lower than the RDA in all make students, and Fe was lower than the RDA in all female students. Among the deficient nutrients, vitamin A showed the lowest % RDA : 48% in the male and 64% in the female students. Among the deficient nutrients, vitamin A showed the lowest % RDA ; 48% in the male and 64% in the female students. The intakes of Ca, Fe, and niacin in the ESWJ were significantly greater than those in the RS and ESWOJ groups, and the vitamin C intake in the ESWJ was greater than that in the ESWOJ(p<0.01). In conclusion, university students in all three groups have a serious imbalance in the nutrient intakes, and the evening class students with a daytime job have unhealthy dietary behaviors in the light of high frequency of eating out and heavy coffee drinking, a rushed eating pattern, and therefore showing a strong need of proper nutritional education for them.

This study was carried out with 436 college students in Chungnam to investigate the relationship between residences and eating patterns of college students. The subjects were devided into two groups; those who live in self-boarding house(SB) and home with parents(HWP). The results were as follows. An average height, weight and BMI were 173.5cm, 66.0kg and 21.9 in male SB and 161.8cm, 50.2kg and 19.2 in female SB and 172.9cm, 67.6kg and 22.6 in male HWP and 161.2cm, 50.9kg and 19.6 in female HWP, respectively. There were no significant differences in the general characteristics between the SB and the HWP. The proportions of disease possession, vitamin/mineral supplements and physical exercise were not significantly different between two groups by residences. Sleeping time of the SB was longer than that of the HWP. And, frequency of cigarette smoking and alcohol drinking of the SB were higher than those of the HWP. The proportions of skipping meals in the SB were higher than those in the HWP. Approximately 40.42% of the SB tended to skip the breakfast, while 11.26% of the HWP did. It turns out that the most common reason why skipped meals was due to a eating habit(44.21%) in the SB and a lack of time(48.85%) in the HWP, respectively. The survey shows that while a great majority of the SB had lunch at campus(50.00%) and home(30.00%), the HWP ate lunch at campus(33.79%) and restaurant(33.33%). About 48% of the SB ate out more than 2~3 times a week compared to 42% of the HWP. The daily intakes of calcium, iron, vitamin A, vitamin B2, niacin and vitamin C in the SB were significantly higher than those in the HWP. The percent RDAs of calcium and iron intakes were lower in female students than in male students. In conclusions, students of self-boarding had more dietary problems than students of home with parents. These results suggest that college students of self-boarding might have low ability of meal management. Therefore, nutrition education for college students is needed, and menus of campus cafeterias should be developed to meet the various needs of students.

PURPOSE: The accurate analysis of urinary stone components is fundamental for studying of the etiology of stone formation and it is essential for the treatment of urinary stone and its prevention. We compared the analysis of urinary stone components during the last two decades. MATERIALS AND METHODS: Stone analysis was performed by Louis C. Herring and Company. The urinary stones were aobtained from January, 1986 to December, 2005. We compared the stone components of the first decade (Group A, 301 cases) with that of the second decade(Group B, 158 cases). RESULTS: The mean age was 47.2+/-14.5 in Group A and 46.0+/-10.2 in Group B(p=0.658). The ratio of males to females was 2.04:1 in Group A and 1.98:1 in Group B(p=0.888). Ureteral stones were the most common stones in both groups. Among all the components analyzed in Group A, calcium oxalate made up 73.1% of the total. Other components found in the stones were uric acid 12.3%, calcium phosphate 8.3%, magnesium ammonium 5.3%, ammonium acid urate 0.7% and cystine 0.3%. In Group B, calcium oxalate was only 56.3% of the total and uric acid was 22.2%, calcium phosphate was 11.4%, magnesium ammonium phosphate was 8.2%, ammonium acid urate was 1.3% and cystine was 0.6%. On comparison of the stones of the two groups, the incidence of calcium oxalate was decreased in Group A(73.1% vs 56.3%, p<0.001). However, the incidence of uric acid in Group B was increased(12.3% vs 22.2%, respectively, p=0.006). There were no notable statistical increases in the frequency of the other components(p>0.05). CONCLUSIONS: In this study, the incidence of calcium oxalate was decreased and that of the uric acid was increased in the recent decade. These changes of stone components probably resulted from the increased animal protein diet.

PURPOSE: Open prostatectomy have been considered primarily when the prostate volume is large(e.g. >75 cc). However, with the development of surgical skills and instruments, transurethral resection of prostate(TURP) can be an alternative. We assessed the feasibility of TURP for patients with large benign prostatic hyperplasia(BPH) by comparing the efficacy of TURP with that of open prostatectomy, retrospectively. MATERIALS AND METHODS: From January 2000 to March 2005, a total of 54 BPH patients with a prostate larger than 75 cc in volume on transrectal ultrasonography underwent surgery in our hospital. Among these patients, 26 patients underwent TURP(Group T) and 28 patients underwent suprapubic prostatectomy(Group O). Group T was subclassified Group T-1(prostate volume 75~100 cc, n=12) and T-2(prostate volume > or = 100 cc, n=14). In the same way, Group O was divided into Group O-1(n=9) and O-2(n=19). Operative time, time to catheter removal, hospitalization, and complications were compared. Operative results were evaluated at 6 months postoperative by comparing preoperative and postoperative International Prostate Symptom Scores(IPSS), maximal flow rates(Qmax) and post void residual(PVR). RESULTS: Preoperatively, there were no significant differences in IPSS, Qmax or PVR between Groups T-1 and O-1 or between Groups T-2 and O-2. Although delta IPSS, delta Qmax and delta PVR improved in Group O-2 more than T-2, there were no statistically significant differences between Group T-1 and O-1. The mean operative time, time to catheter removal, and hospitalization were shorter in Group T than Group O. Postoperative complication rates were similar in the T and O groups. In Group T, there was no TUR syndrome, but urinary tract infections and urethral stricture were more common than in Group O. However, Group O had higher incidences of severe complications, including wound infection or bleeding requiring transfusion. CONCLUSIONS: Open prostatectomy is commonly considered when prostate volume is greater than 75 cc. If enough resection is performed, TURP is a valuable non-invasive surgical method with respect to absence of incision, effective symptom improvement, and short hospitalization in symptomatic BPH patients who have prostate volume less than 100 cc.

Percutaneous vertebroplasty (PVP) is a minimally invasive surgical treatment for patients with osteoporotic vertebral compression fracture (OVCF) and can rapidly alleviate pain, improve mobility, and stabilize the vertebrae. However, it has the potential to cause complications such as cement embolism. A 55-year-old female presented with pain in the lumbar region as a chief complaint. PVP was performed after diagnosis of acute OVCFs at L4 and L5. No abnormal symptoms were reported after surgery, but a large cement embolism was observed in her right atrium and ventricle. After discussion in a multi-disciplinary team, the large cement embolism was successfully removed by a combination of endovascular procedure and an inferior vena cava exploration. Surgeons must consider the possibility of intra-cardiac cement embolism after PVP. A hybrid approach of an endovascular procedure and a vascular surgery may be a reasonable treatment option to minimize the surgical procedure in cases of a large intra-cardiac cement embolism.

BACKGROUND AND OBJECTIVES: This study was to done to determine the value of PROPELLER diffusion-weighted imaging in detecting cholesteatoma. SUBJECTS AND METHOD: Sixty-five patients were evaluated by preoperative magnetic resonance imaging (MRI) with PROPELLER diffusion-weighted imaging. Of 65 patients, 16 patients had chronic otitis media without cholesteatoma and 49 patients with cholesteatoma. Surgical and pathologic findings were compared with the preoperative findings by PROPELLER diffusion-weighted imaging to assess the sensitivity, specificity, positive and negative predictive values. RESULTS: In 49 patients with cholesteatoma, high signal intensity compatible with cholesteatoma was found in 46 patients, whereas in 16 patients without cholesteatoma, high signal intensity was not detected in any of them. The sensitivity, specificity, positive and negative predictive values for PROPELLER diffusion-weighted imaging were 94.1%, 100%, 100%, and 84.2%, respectively. CONCLUSION: PROPELLER diffusion-weighted imaging can be a useful tool in detecting cholesteatoma.
