Hantavirus is a genus of the Bunyaviridae family causing two serious diseases, hemorrhagic fever with renal syndrome (HFRS) and hantavirus pulmonary syndrome (HPS). Puumala virus is a member of hantavirus originally found in Europe, and its natural reservoir is Clethrionomys glareolus. It is also associated with the hurnan disease nephropathia epidemica, a milder form of HFRS. To identify the hantaviruses in bats, bats were collected from Jeong-Sun, Won-Joo, Chung-Ju and Hwa-Cheon area in Korea, and nested RT-PCR was performed with serotype specific primer from M segment. Interestingly, Puumala virus was detected in bats (Rhinolophus ferrum-equinum) only from Won-Joo. The 327 bp nested RT-PCR product, was sequenced. The sequence database search indicates that the sequence is homologous to the published sequence of Puumala viruses. The sequence similarities were ranged from 71% to 97%. The highest sequence similarity was 97% with Puumala virus Vranicam strain, and the lowest was 71% with Puumala virus K27 isolate. Puumala virus Vranicam strain was isolated from a bank vole (Clethrionomys glareolus) in Bosnia-Hercegovina. Puumala virus K27 was isolated from human in Russia. This analysis confirms that bats (Rhinolophus ferrum-equinum) in Korea are natural reservoir of Puumala virus.

This study was performed to investigate nurses' perception for nutrition education. The subjects of this study were 197 nurses and 94 nursing assistants working at hospitals in the Kyung-nam area. The survey was conducted by using a self-administered questionnaire in November, 2001. The results were as follows : Sixty-seven point seven percent of the subjects were nurse, 32.3% were nursing assistant. Average age of subjects was 26.9 years old, average nursing experience was 5.7 years, and 70.7% of the subjects graduated from a junior college. The average nutrition knowledge score was 14.3+/-2.5 out of possible 20 points. Seventy-four point two percent of the subject responded that nutrition education is very necessary for patient, and positive responses in the nurse were higher than that nursing assistant(p<0.001). Only 8.6% of the subjects had nutrition education training. The perceptions about a suitable person for nutrition counseling and nutrition education indicated dietitian(69.3%) and nurse(21.3%). Fifty-two point eight percent of the subjects responded that they would not participate in nutrition education themselves and the main reason for this was that they believed lack of expert knowledge(43.4%), and that such courses should be taught by specialist(40.5%). Forty-eight point eight percent of subjects had nutrition counseling experience for patient, and nurses, married nurses and those over 2 years of nursing careers had significantly higher nutrition counseling experience for patient than nursing assistant, unmarried nurses and those under 2 years of nursing careers(p<0.05~p<0.001)

OBJECTIVES: Some emotional components, such as self-esteem, depression and anxiety, have been reported to be associated with paranoia in non-clinical population and schizophrenia patients. The aim of this study was to investigate the correlation between self-esteem and paranoia in healthy controls, in ultra-high risk for psychosis and schizophrenia patients. METHODS: 34 subjects with recent onset schizophrenia, 36 subjects with ultra-high risk for psychosis, and 44 healthy volunteers participated in this study. A detailed assessment was made of the paranoia, self-esteem, depression, and anxiety. RESULTS: In all three groups, there were a negative correlation between paranoia and self-esteem, and positive correlations between paranoia and depression and anxiety. In healthy control, lower self-esteem showed a trend to predict higher paranoia, and in ultra-high risk for psychosis, this trend tern on statistically significant level, and in recent onset schizophrenia group, this correlation was disappeared. CONCLUSION: The individual who have lower self-esteem showed higher paranoia tendency under delusional level, but after formation of persecutory delusion, the tendency was disappeared. This result supports the hypothesis that persecutory delusions are a defense against negative affective process.

OBJECTIVES: The purposes of this study were to estimate the effect of mandibular advancement device (MAD) and to evaluate the influence of the advancement amount of mandible in the application of MAD for obstructive sleep apnea (OSA) patients. METHODS: From the patients who were diagnosed as OSA by polysomnographic study at Seoul National University Bundang Hospital from January 2007 to February 2009, the patients who chose MAD as treatment option were included in this study. All the patients' data including clinical records and polysomnographic studies (both pre- and post-treatment) were reviewed and analyzed. RESULTS: Successful results were obtained in 65 patients of 86 patients (75.6%). In the follow-up period, mild discomfort of anterior teeth or temporomandibular joint (TMJ) were described in 28 patients, especially in the cases the amount of mandibular advancement were more than 7.0 mm. There was no direct relationship between the amount of mandibular advancement and clinical outcome. CONCLUSION: MAD was effective treatment option for the OSA patients regardless of severity. For the prevention of potential dental complications, the amount of mandibular advancement should be considered at the time of MAD treatment.

In these days, computing environment turns to web environment and a lot of hospitals build information system. A medical services through the web provide patients and doctors with convenience and help experts to communicate with each other. Initially, web provided static text information, but nowadays needs of interactivity between client and server is increasing. In order to diagnose heart diseases, we use 12 channel ECG, stress ECG, holter ECG, etc. These data are a lot of correlation with each other but there are little system managed them with integration. To enhance management efficiency and share medical information, it is necessary to develop integrated ECG management system based the web. In this paper, we use common object request broker architecture(CQRBA) to implement the system. The CORBA is to apply object oriented concept to web. We can implement application easily and reduce costs to maintain and repay because server objects and client objects exist independently. We developed a System to integrate these data using network and to raise management efficiency. we focus on the performance of object web and the implementation of ECG management system based on the web.

Neovascular glaucoma is considered to be one of the most difficult forms of glaucoma to control. In neovascular glaucoma fibrovascular tissue grows over the surface of the iris and trabecular meshwork. Many modified filtering surgery with artificial drainage devices have been tried in attempts to maintain openings for aqueous humor to leave the eye. Modified trabeculectomy was performed with inexpensive easily available simple silicone tube in 8 eyes with neovascular glaucma. Of the 8 eyes, 6 had postopeoative intraocular pressures lower rhan 25mmHg through a mean follow-up period of 6 months.

OBJECTIVES: This study compared the nutritional status of child-bearing age women between the Democratic People's Republic of Korea (North Korea) and the Republic of Korea (South Korea). METHODS: The data presented in the DPRK Final Report of the National Nutrition Survey 2012 was utilized for the nutritional status and food intake of North Korean women. To produce the South Korean women's data comparable to those of North Korean women, the data from the 2012 National Health and Nutrition Survey were analyzed and the data presented in the 2010 Report of the Korean Agency for Technology and Standards were utilized. RESULTS: The prevalence of maternal anemia (blood hemoglobin < 12.0 g/dL) was over 30% in all the age groups of North Korean women and 8.9%, 14.2%, 16.4% in 20-29, 30-39, 40-49 year old South Korean women, respectively. The prevalence of maternal protein-energy malnutrition (Mid-Upper Arm Circumference < 22.5 cm) was 25.2%, 21.4%, 21.8% in 20-29, 30-39, 40-49 year old North Korean women, respectively and less than 10% in all the age groups of South Korean women. Result of dietary diversity comparison showed that North Korean women consumed less food than South Korean women at all food groups: grains, fruits, vegetables, meat, and dairy. Percentage of North Korean women having consumed protein rich foods-meat and fish, eggs or dairy products-were much lower than those of South Korean women. CONCLUSIONS: The striking disparity of nutritional status between South and North Korean women indicates that nutrition support for North Korean women is essential in the process of preparation for a unified nation.

The simultaneous occurrence of primary glomerulonephritis in identical twins has been rarely reported previously. It has suggested that genetic factors may play an important role in the pathogenesis of primary glomerulonephritis. We describe a pair of 17-year-old identical twin brothers with asymptomatic proteinuria, one with histologically proven minimal change disease and the other with focal segmental glomerulosclerosis. HLA typing in twin brothers revealed an identical phenotype consisting of A25, A33, B44, B54, Cwl, Cw7, DR7 and DRB1. To our knowledge, this is the first case of glomerulonephritis in identical twins in Korea.
