Vibrio mimicus, marine bacteria pathogenic for fish, can causes acute gastroenteritis in human. Iron limmited condition like in human body, may change the surface structure of V. mimicus. In this study we obse'rved the effect of iron limmited condition on outer membrane protein of V. mimicus. Ethylenediamine-di (O-hydroxy-phenylacetic) acid (EDDA), an iron chelator, delayed the time to reach expotential growth of V. mimicus in brain heart infusion medium from 3 hours to 20 hours. Outer membrane protein of V. mimicus-CON (cultured in BHI) and V. mimicus-EDDA (cultured in BHI contain EDDA) were seperated by 1% sarcosine from total cell envelop. SDS-PAGE of V. mimicus-EDDA and V. mimicus-CON showed similar protein profiles contain 37 kDa major protein but 86 and 90 kDa protein were induced differently. Immunological properties of above protein were determined by ELISA and western blotting. 86 kDa EDDA- specific OMP was induced in V. mimicus (isolate 96-1), V. parahaemolyticus (serotype 09), V. alginolyticus (isolate 95-1), E. coli (human isolate) and V. vulnificus ATCC 27562 in iron limmited condition.

PURPOSE: The purpose of this study is to verify the effects of the Qigong training program on the anxiety and labor pains of primipara. METHOD: The research subjects were a total of 60 primipara who consulted a doctor regularly concerning their antenatal care. Among them, 30 people were the experimental group, and the other 30 people were the control group, and were selected as homogeneous with the experimental group. The degree of anxiety and labor pains were measured by State-Trait Anxiety Inventory(STAI) and Graphic Rating Scale(GRS). SPSS WIN 11.0 was used for data analysis. Obstetric and general characteristics between experimental and control groups, and a homogeneity test of state and trait anxiety were done by both X2 test and t-test. The hypothesis testing was analyzed by ANCOVA with a covariate of pretest value. RESULT: The first hypothesis, 'Primipara who join the Qigong training program have lower anxiety than those who do not join' was supported (F=28.8, p<.000). The second hypothesis, 'Primipara who join the Qigong training program have lower labor pain than those who do not join' was unsupported. CONCLUSION: It was verified that the Qigong training program was effective in alleviating anxiety; however it did not have any effect on relieving labor pain, so more in-depth research is needed later on.

A novel bacteriophage, designated as VPP97, that infects the strains of Vibiro parahaemolyticus (hallophilic, Gram-negative bacterium) isolated most commonly from marine environments, has been discovered, and several of its properties have been determined. The plaques were clear and sized 0.6-1.0 mm in diameter. The virion forms a single band on 70% sucrose gradient and p1.50 CsC1 gradient by sucrose gradient centrifugation and CsCI gradient centrifugation respectively. It has a hexagonal head and a relatively long tail, as shown by electron microscopy. Vibrio alginolyticus, Vibrio fluvialis and Vibrio furnissii were also sensitive to this phage It was almost totally inactivated at 70 degree C and at pH below 5 or over 10. The nucleic acid of VPP97 is composed of DNA. The VPP97 had 9 specific structural proteins sized between 21.5 kDa and 97.4 kDa on SDS-PAGE. When V. parahaemolyticus cultures were treated with either phage VPP97 or one of the several antibiotics for 2 hours, the viable number of V. parahaemolyticus treated with the phage VPP97 is lower than that treated with chloramphenicol, erythromycin or penicillin, but not lower than that treated with tetracycline. Mice that have responded to the phage treatment revealed the lower numbers of V. parahaemolyticus in small intestine and less damage on small intestine compared to the untreated mice. Therefore, we suggest that the phage treatment appears effective to the infection by V. parahaemolyticus.

The halophilic bacterium, Vibrio vulnificus, causes acute fulminating wound infections and septicemia in human. Especially the septicemia shows high mortality above 50%. In Korea, septicemia by V. vulnificus was reported at westem and southern coast in every year. Here, we try to isolate this V. vulnipcus at Kyoung-nam area and coast of Pusan during 1996. Purposed sites were Dadaepo, Songjung, Chungsapo and Mipo of Pusan and Kijang, Ilkuang, Juksoung, Dongam, Waljun and Chilam of southern sea. Total 40 strains of V. vulnipcus were isolated from sea samples. Biochemical characteristics of isolated V. vulnificus were almost same with reference strain V. vulnificus ATCC 27562 on Farmer's tests and on API 20E kit test. V. vulnificus isolates in 1996, fermented cellobiose and salicin but arabinose. and had resistance to 7% sodium chloride.

In Korea, there are about 8 million motor vehicles and one-fourth of it is motorcycle. Last year Korean government report on the motor vehicle accidents claimed 12,781 cases of motorcycle accidents and it account for 5.1% of all of motor vehicle accidents occurred in Korea. But this is too broad analysis and lack of statical values. In general, most of people think motorcycle rider will suffer or die from head injuries sustained with motorcycle accident. Even though mandatory law on wearing helmet during motorcycle ride, but we see too many motorcycle riders not wearing helmet, especially in teenagers. The loss of young person by accident is great loss for family, society and economy of nation. No one will doubt the effectiveness of helmet on reduced incidence of head injuries. And multiple studies from United States of America have clearly demonstrated the benefit of helmets in motorcycle accidents. The following study was undertaken to determine the relationship between head injuries and helmet use in motorcycle accident, as well as analysis of general motorcycle accident.

BACKGROUND: The yields of plateletpheresis products are important to meet standard platelet transfusion doses. The use of single donor platelets (SDPs) has been increased substantially worldwide. Korean Red Cross decided to supply and started collection of SDPs since January, 2000. This study evaluates platelet yields of plateletpheresis and plasmapheresis of Korean Red Cross Nambu blood center. METHODS: The records for SDPs collected by Amicus(TM) (Baxter, Deerfield, IL, USA), MCS+ (Haemonetics, Braintree, MA, USA) and Trima (Gambro BCT, Lakewood, USA) between Jan. 2005 and Nov. 2005 were evaluated. The records for plasma collected by Autopheresis-C(TM) (Baxter,Deerfield, IL, USA), MCS(TM), PCS 2 (Haemonetics, Braintree, MA, USA) between Jan. 2005 and Nov. 2005 were also evaluated. RESULTS: Platelet yields of SDP less than 3 x 10(11) accounted for 6.45% of all collections. The rate of SDPs which platelet yields less than 3 x 10(11) collected by AMICUS is 4.84%, MCS+ is 7.72%, TRIMA is 7.01%. The rate of plasmapheresis products under the criteria is 0.7%. Plasma collected with Autopheresis-C(TM) made a concern about break down of filtration pore and occuring of hemolysis during apheresis procedures. CONCLUSION: Platelet yields less than 3 x 10(11) accounted for 6.45% of all collections. The rate of plasmapheresis products under the criteria is 0.7%. This study demonstrated that qualfied management and thorough understanding of the plataletpheresis technology are necessary to increase productivity of SDPs with platelet yields 3x1011 or over.

Purpose: This study aimed to compare the attitudes of nurses and physicians toward neonatal palliative care and identify the barriers to and facilitators of neonatal palliative care, with the goal of improving palliative care for infants in neonatal intensive care units (NICUs). Methods: This cross-sectional study analyzed data from the NICUs of seven general hospitals with 112 nurses and 52 physicians participating. Data were collected using the Neonatal Palliative Care Attitude Scale questionnaire. Results: Only 12.5% of nurses and 11.5% of physicians reported that they had sufficient education in neonatal palliative care. In contrast, 89.3% of the nurses and 84.6% of the physicians reported that they needed further education. The common facilitators for both nurses and physicians were: 1) agreement by all members of the department regarding the provision of palliative care and 2) informing parents about palliative care options. The common barriers for both nurses and physicians were: 1) policies or guidelines supporting palliative care were not available, 2) counseling was not available, 3) technological imperatives, and 4) parental demands for continuing life support. Insufficient resources, staff, and time were also identified as barriers for nurses, whereas these were not identified as barriers for physicians. Conclusion It is necessary to develop hospital or national guidelines and educational programs on neonatal palliative care, and it is equally necessary to spread social awareness of the importance of neonatal palliative care.

Purpose: This study aimed to investigate student nurses’ satisfaction by type of clinical practicum and to determine predictors of clinical competence in pediatric nursing. Methods: A total of 189 Junior and Senior student nurses across seven colleges in the Busan Metropolitan City were enrolled in the study. The participants completed a structured questionnaire containing items about their learning satisfaction with different types of pediatric nursing practicums and their clinical competence. Data were analyzed using the mean, standard deviation, independent t-test, ANOVA, and multiple regression analysis. Results: Regarding satisfaction with each type of clinical practicum, the mean satisfaction score (out of 10) was 8.18±2.26 for on-site clinical rotations and 7.35±2.20 for alternative practicums. Among the different types of alternative practicum approaches, those with a satisfaction score of 7 or higher included fundamental nursing skills, watching videos, simulation etc., while those with a satisfaction score of less than 6 were virtual simulation and problem-based learning. The predictors of clinical competence in pediatric nursing were learning satisfaction with practice, school year, and alternative practicum, accounting for 35.0% of the variance in clinical competency. Conclusion It would be helpful to combine on-site clinical rotations with alternative practicum approaches and to develop various alternative practice programs using simulation practice, virtual reality, immersive interactive systems, and standardized patients to enhance students’ clinical competency.
