1.Trend and Prediction of Urban Family Expenditure for Health Care.
Korean Journal of Preventive Medicine 1995;28(2):347-363
The increase of health care expenditures is an important problem in the almost countries. Also, suppression of the health care expenditures is an important problem in the health field of Korea since the national health insurance for total people in 1989. Thus, it is very important to grasp the change of the health care expenditures of family and proportions of the health care expenditures to total expenditures of family, because they are the basis of national health care expenditures in Korea. While the health care expenditures of urban family were increased during 1980-1993 by 12.8% annually, the total expenditures of urban family were increased by 14.8% annually. consequently, the proportions of health care expenditures to total expenditures were decreased from 5.98% to 4.76%. The proportions of health care expenditure for 3 years to come were predicted to 4.75% in 1994, 4.67% in 1995, and 4.63% in 1996 by the time-series ana]ysis. That is, it was predicted that they would be decreasing slowly. The product elasticity of health care expenditure was less than 1 in the multiple regression analysis, so the health care is normal good rather than superior good. Therefore, it seems that the household economy is able to bear the expense pursuing the improvement of quality of health care by actualizing the medical insurance fee.

Korean Journal of Preventive Medicine 1995;28(2):334-346
To investigate the factors influencing workers' perception and attitude toward special periodic health screening test for workers, a survey with self-administered questionnaires was performed on 279 workers who had special periodic health screening test from september 1 to October 15, 1994. A study model was developed by modifying the health belief model. The end and intermediate response variables of the model were the voluntary participation and necessity perception on the special screening for workers, and The result of analysis was consistent with the study model. Rates for the necessity perception and voluntary participation on the special1 screening for workers were 77.2%, 79.2%, respectively. Factors influencing on the voluntary participation were necessity perception, benefit of special screening for workers, and cue to action. And on the necessity perception were susceptibility and severity to occupational disease, knowledge to special screening for workers, and support of company. General and occupational characteristics influencing on the susceptibility and severity to occupational disease were sex, age, educational level, work duration, and health education. On the knowledge to special screening for workers were age, educational level, work duration, and locus-of-control. On the benefit of special screening for workers were age, locus-of-control, pride on health, and health education. Therefore, to increase the voluntary participation and necessity perception on the special periodic health screening for workers, l) if a worker is judged as occupational disease, the judgment should be widely known in his workplace, 2) the screening result forms should be directly sent to the workers themselves, 3) for the positivity of employers, the campaign and education program subjected to them should be planned, 4) health education should give the first consideration to the younger, lower educational level, and newly employed women, and its frequency should be increased and it should be more frequently dealt with occupation-related subjects, and 5) the employers should have a careful concern in not being disadvantageous to workers due to result of screening.

Korean Journal of Preventive Medicine 2004;37(1):37-43
OBJECTIVE: This study was carried out to understand the prevalence and risk factors of green tobacco sickness (GTS) among Korean tobacco harvesters. METHODS: The authors conducted a questionnaire among the tobacco harvesters (1, 064 persons from 555 out of 723 tobacco harvesting households) in Cheongsong-gun for 4 days from May 7 to 10, 2002. RESULTS: The study subjects were 550 males and 514 females. The recognition and experience of GTS up until 2001 were 96.4% and 61.9%, respectively. The prevalence of GTS in 2001 was 42.5%, and was significantly higher in females than in males (59.0% vs. 26.6%, p< 0.01). The incidence density of GTS according to the number of workdays in 2001 was 12.3 spells/100 person' days. The GTS symptoms reported by the tobacco harvesters in 2001 were dizziness in 441 cases (97.6%), nausea in 414 (91.6%), headache in 349 (77.2%) and vomiting in 343 (75.9%). The use of gloves, hat and wristlets, sweating at work and the number of working hours significantly increased the prevalence of GTS (p< 0.05). Multiple logistic regression analysis was used to determine the factors significantly associated with GTS. Odds ratios for smoking, working over 10 hours and sweating at work were 0.26 (95% CI: 0.19-0.35), 1.64 (95% CI: 1.26-2.14) and 1.60 (95% CI: 1.14-2.25), respectively. Of those who reported GTS in 2001, 311 cases (68.8%) underwent treatment from their local medical facilities. CONCLUSION: In Korea, there are many tobaccoharvesting households, and most may be stricken with GTS. More extensive epidemiological studies, including heincidence and associated risk factors, are expected and a surveillance system including measurements of cotinine in urine should be conducted.

OBJECTIVES: This study was carried out to measure the urinary cotinine concentrations of Korean tobacco harvesters with green tobacco sickness (GTS). METHODS: We conducted a questionnaire survey and measured the urinary cotinine concentrations among the cases who visited six health subcenters and the emergency room in the Health Center and County Hospital after harvesting tobacco leaves in Cheongsong-gun, from Jul 15 to Aug 15, 2002. Ten suspected GTS cases were compared to 10 controls matched for residence, age, and sex. Urinary cotinine was analyzed with a reverse-phase high performance liquid chromatography (HPLC) system and expressed as geometric mean and standard deviation. The data collected were evaluated using the SPSS/win statistical package and the urinary cotinine concentrations between the two groups were analyzed by Mann-Whitney U test. RESULTS: In both the 10 cases and controls, there were 3 males and 7 females. Ages ranged from 22 to 70 years old. Half of the cases were reported within the 6 hours between 12:00 pm and 17:59 pm. The median time from starting work to initially feeling ill was 4.3 hours (min. 2.5; max. 11.0). The GTS symptoms reported were nausea in 10 cases (100.0%), dizziness in 9 (90.0%), weakness in 8 (80.0%), headache in 7 (70.0%) and other symptoms. The geometric mean of urinary cotinine concentrations was significantly higher (p<0.01) in cases at 497.6 +/- 2.5 ng/ml (min. 73.1; max. 2,574.3) than in controls at 32.7 +/- 1.8 ng/ml (min. 13.3; max. 76.9). CONCLUSIONS: Our study suggests that many tobacco harvesters may suffer from GTS in Korea. Therefore, it is very important for doctors to diagnose exactly the GTS. Also we must develop the methods which can prevent GTS, and simple methods of analysis for urinary cotinine.

BACKGROUND: Tumor necrosis factor-alpha(TNF-alpha) has been thought to play a major role in neurological injury during global brain ischemia and subsequent reperfusion following resuscitation in cardiac arrest. So, we hypothesized that the elevation in TNF-alpha was dependent upon the duration of the global brain ischemia, and related to delayed neuronal damage. METHODS: Fourteen rats were divided two groups ; 1 minute-cardiac arrest group(n=7) and 3 minute-cardiac arrest group(n=7). we induced cardiac arrest by chest compression and damping of tracheal tube for 1 minute and 3 minutes respectively. And then, resuscitation was initiated. To measure the plasma activity of TNF-alpha, blood samples were drawn before and at the end of cardiac arrest, and 30, 60, 90, and 120 minutes after initiation reperfusion. At 72 hours after resuscitation, the ND(neurologic deficit) score was determined and the histopathologic outcome of hippocampal CA1 neuron was observed by the percent dead hippocampal CA1 neurons. RESULTS: 1. TNF-alpha level during the early reperfusion period(<2h) was significantly increased in 3 min-cardiac arrest group compared with 1 min-cardiac arrest group(p=0.0001). 2. There was a no significant difference of neurologic deficit score between 1 min- and 3 min-cardiac arrest. 3. Percent dead hippocampal neurons were significantly increased in 3 min-cardiac arrest group compared with 1 min-cardiac arrest group(9.1+/-1.2% vs 1.2+/-0.9%, p<0.05). CONCLUSION: The results suggest that longer duration of global brain ischemia causes a more profound increase in plasma TNF-alpha level during the early reperfusion period(<2h) and more delayed neuronal damage than lessor duration of global brain ischemia, and that increase in TNF-alpha level during the early reperfusion period(<2h) is related to delayed neuronal damage.

OBJECTIVES: An outbreak of food poisoning occurred among the baseball club students at a high school in Ulsan city in 2014. An epidemiological investigation was carried out to examine the infection source and the transmission route of pathogen, and to prevent a recurrence. METHODS: A questionnaire survey was conducted for 26 male students and 2 food handlers. Rectal swabs were examined in 7 students and the 2 food handlers, and an environmental investigation was performed. A retrospective cohort study was used to evaluate the association between risk factors and disease. RESULTS: The attack rate was 35.7% (10 persons/28 persons) from June 9 to 14, and Enterotoxigenic E. coli ST/LT was isolated from 7 among 28 persons. The study revealed that no food was a significant risk factor for the outbreak. There were no connection between environmental factors and the outbreak. CONCLUSIONS: The major risk factors for this outbreak were presumed to be the contaminated ice cube and ice making machines and eating ice cube from the machines. More strict personal and environmental hygiene need to be enforced to prevent such outbreaks.

Although very rare, the incidence of tricuspid valve regurgitation after blunt chest trauma has risen in line with the increasing rate of car accidents and steering wheel trauma. It is easy to miss the diagnosis of tricuspid valve regurgitation following blunt chest trauma because most patients feel no symptoms at trauma, and the condition is sometimes overlooked for a long period of time due to its mild symptoms. A 49-year-old man suffered dyspnea on exertion for 1 month due to right heart failure 8 years after accidentally falling from a third floor. Preoperative echocardiography revealed severe tricuspid valve regurgitation resulting from prolapse of the anterior leaflet with annular dilatation. The patient underwent tricuspid valvuloplasty with a 36-mm Carpentier tricuspid ring. Intraoperative transesophageal echocardiography showed mild tricuspid valve regurgitation. We report a case of successful native valve salvage of ruptured tricuspid valve after blunt chest trauma, and present a review of the relevant literature.

Journal of Korean Academy of Nursing 2006;36(6):1076-1084
PURPOSE: The purpose of this study was to evaluate a cognitive behavioral anger management intervention in order to increase self-consciousness and decrease anger among Korean military men. METHODS: A quasi-experimental design was used for this study. Ninety two soldiers were screened for unhealthy anger expression using a questionnaire. Among them, 26 soldiers who showed unhealthy anger expression were selected for this study. They were matched by rank and assigned to either a treatment or control group. The treatment group received the intervention three consecutive times, once a week and for 120 minutes per session. Participants were assessed before and after the intervention for anger (the State-Trait Anger Scale) and self-consciousness (Self-consciousness Scale). Data was analyzed using descriptive statistics, chi-square-test, Mann-Whitney test, and Wilcox on signed rank test. RESULTS: There was no statistically significant decrease in anger or increase in self-consciousness between the two groups following treatment. However, there was a significant increase in private self-consciousness in the treatment group after the intervention(p=.006). CONCLUSION: The cognitive behavioral anger management program improves private self-consciousness in soldiers. However, Additional research is needed to explore whether long-term intervention is more effective for anger control in the military setting. The findings from this study suggest that more attention should be given to mental health care for Korean soldiers.

Overcrowding of emergency department is a serious and growing problem at St. Mary's Hospital. This has motivated the development of short-stay unit(SSU) as an alternative ward to routine hospital admission and ED discharge. In our hospital a SSU begun to admit patients in January 6, 1997. the SSU received 247 patients from the ED during the eight month interval(January 6, 1997 to August 31, 1997). To examine the utilization of the SSU in ED, we retrospectively analyzed 247 patients admired in SSU from the ED, and compared the average hours per patient with acute gastroenteritis spent in the ED doing the 2-month intervals before(July-August 1996) and after(July-August 1997) the establishment of the SSU. The following results were obtained; 1. The total patients consist of EM 92(37.2%), GS 48(19.4%), IM 24(9.7%), PS 21(8.5%), OS 20(8.1%), OBGY 14(5.7%) and others 28(11.3%). 2. The results of EM patients admitted in SSU from ED 1) Sex ratio of male to female was 1:1.1 and the mean age was 37.3+/-16 years. 2) In diagnosis, acute gastroenteritis was 29 cases(31.5%), multiple contusion 14 cases(15.2%), drug intoxication 12 cases(13%), limb laceration 6 cases(6.5%), tendon rupture offhand 6 cases(6.5%), and others 19 cases(20.6%). 3) Mean length of stay in ED was 9.18 hours. 4) Among 92 patients to the SSU, 79 patients(85.9%) were discharged, 11 patients(11.9%) formally admired to hospital and 2 patients(2.2%) transferred to otherhospital. The mean hospital stay time of the patients admitted to SSU was 2.6 days. 3. There was a significant reduction in the average stay time spent in the ED by treat-and-releasing patients with acute gastroenteritis after the establishment of the SSU(from 14.65+/-9.6 to 7.52+/-5.4 hr/patient, p<0.001). Conclusively, the establishment of the SSU can shorten the average stay time that treat-and-releasing patients spend in the ED, and reduce the number of admixed patients waiting in the ED.
