This study was designed to investigate perception of job rotation and an organizational commitment of staff nurses working at K hospital and find the way of increasing an organizational commitment for the groundwork for efficient changes in the nursing staff. Data were collected from Aug. 20 to Aug. 28, 2004 through self reporting questionnaires taken by 318 nurses working at a hospital. The three structured instruments were used for collecting the data; Questionnaires for measuring the perception of job rotation, Questionnaires for measuring the utility and the problem of job rotation, and Mowday's Organizational Commitment Questionnaires. The Results were as follows : 1. 66.0% of 318 staff nurses approved of regular job rotation; 34.0% of them disapproved 34.3% of them wanted to get transferred to another department; 65.7% of them didn't. 2. Of general characteristics, age(F=17.469, P=.000), marital status(F=-2.781, P=.006), religion(F=5.688, P=.001), education level(F=8.816, P=.000), position(F=15.591, P=.000), a total clinical career(F=11.606 p=.000) and field in practice(F=4.206, P=.000) were significantly related to an organizational commitment. 3. There is relatively positive correlation between the perception of job rotation and an organizational commitment. In conclusion, the utility of on the job rotation and organizational commitment showed the positive correlation.

Intussusception is one of the most common cause of bowel obstruction in infant under the two years old, especially in male. Clinical analysis was enrolled on 54 intussusception cases who were diagnosed by ultrasound and treated by non-operative reduction at the Presbyterian Medical Center from June 2005 to May 2007. The results were as follow. 1) There was the most common(40.7%)between thirteen and twenty four months on the distribution of age. Male(72.2%) and female(27.8%) were in the ratio of 2.6:1 on the distribution of gender 2) The frequent symptoms were abdominal pain with grizzle(100.0%), vomiting(66.7%) and diarrhea(33.3%). There was a significant difference among them(p<0.05). There was the most common(46.3%) between 10,000/$mm^3$ and 15,000/$mm^3$ in the result of WBC. 3) 42.6% of patient at a private hospital performed primary care. The treatment after initiating the symptom of intussusception was performed between 6 hrs and 12hrs (37.0%). 4) The most common type and portion of intussusception were ileo-colon(98.1%) and hepatic flexure (68.5%). 5) 88.0% at air reduction and 86.2% at barium reduction were successful. The reduction rate were similar to both techniques. There was no significant difference between them(p>0.05).

Although there is circumstantial evidence that infectious bronchitis(IB) in the Korean layer industry has contributed to severe economic losses, the seroprevalence against IB virus(IBV) and risk factors associated with seropositivity are not well known. During May to October 2007, 820 blood samples were randomly collected from 41 laying hen flocks(20 birds in each flock) with $\geq$ 3,000 birds of 18 week of age or older in three provinces of Korea. The samples size was determined considering a flock-size range of 3,000-65,000 birds, an expected bird-level seroprevalence of $\geq$ 15%, and a 95% level of confidence. Serum samples were examined using a hemagglutination inhibition test for antibodies to IBV. The overall apparent flock-level seroprevalence was 46.3%(95% CI, 31.1-66.6) with no statistically significant differences among provinces(X=1.205, p>0.05). There were 19 positive flocks with one to eight seropositive birds, and 11 of these had one or two seropositive birds. None of the measured parameters were significantly associated with seropositivity against IBV in a subsequent multivariable logistic regression analysis. A longitudinal risk factor studies considering management and vaccination characteristics possibly associated with the IBV flock prevalence would be beneficial.

To examine the effects of vaccination against Babesia gibsoni infection in dogs, 15 normal mixed-breed dogs(5 month to 1 year old) divided into 3 groups with 5 dogs in a group. One of them was selected as control group(group A) and others were selected as experimental groups(group B and C). The group B was vaccinated with sonicated antigens and the group C was vaccinated with 0.2% of formalin treated antigens. The results obtained in the examination were summarized as follows : 1. In the western blot, the lane A revealed specific two bands on the regions of 54kd and 100kd, respectively. 2. After the first vaccination, the antibody titers of group B and C were higher 5 times(1 ： 200) than those of control group(1：40). After the second vaccination, the antibody titers of group B and C have not changed. When challenged with the protozoa(Babesia gibsoni), the antibody titers(1 : 5,000) were elevated in all groups. But these were not exceeded over 1 ： 5,000 for 4 weeks. 3. After challenge, the peak time of increased numbers of the protozoa was the 15th day (12-18 days) in all groups. During these days, the rate of parasitized erythrocytes in control group was 55.0${\pm}$5.4%. But those of group B and group C were 26.0${\pm}$6.4%, and 15.6${\pm}$7.8％, respectively. 4. After challenge, all of the values of PCV, Hb, RBC were shown to decrease in all of the control and experimental groups. 5. The total leukocytes counts are shown a tendency of reduction in all groups after challenge. 6. In all groups, there were increase in lymphocytes and monocytes after challenge.

This study was designed to investigate the characteristics of corneal ulcers in dogs with chronic kidney disease (CKD). Medical records of dogs that had been diagnosed with corneal ulcers and chronic kidney disease at Haemaru Referral Animal Hospital between April 1, 2011 and March 31, 2016 were investigated. A control group was randomly selected during the same time period. This group included patients with corneal ulcers but no evidence of systemic disease. The mean healing time of superficial corneal ulcers in the CKD group was 21.0 ± 15.0 days. This was a significantly longer healing time than was observed in the control group (11.0 ± 6.6 days, p = 0.019). The incidence rates of uveitis and keratoconjunctivitis sicca in the CKD group were significantly higher than in the control group (p = 0.000 and p = 0.026, respectively). Additionally, non-healing ulcers had significantly elevated white blood cell counts, while those with healing ulcers had WBC counts within the normal range in CKD group (p = 0.000). This study revealed that corneal ulcers in CKD patients would be delayed epithelial healing process and accompanied by ocular disease which affected to corneal healing compared to non-CKD patients.

Purpose: Preterm infants are very susceptible to malnutrition because of a lack of storage of nutrients, immature digestion and metabolism, and accompanying diseases associated with prematurity. The purpose of this study was to evaluate the effects of nutritional support by the pediatric nutritional support team (pNST) on the clinical course of preterm infants in the neonatal intensive care unit (NICU). Methods: Between July 2003 and July 2006, 48 preterm infants who were admitted to the NICU at Seoul National University Bundang Hospital were included. The subjects were divided into the following two subgroups according to the presence of NST activity; pre-NST group (n=23) and NST group (n=25). Hospital records were reviewed retrospectively. Results: Forty-eight preterm babies were included (M：F=27：21; gestational age, 25~33 weeks). A dietician, pharmacists, or the pNST participated in the prescription of total parenteral nutrition (TPN) more rapidly in the NST group (p=0.000). The fasting periods and TPN administration periods were significantly decreased in the NST group compared to the pre-NST group (p=0.017 & p=0.001, respectively). The doses of calories, protein, and lipids administered via TPN were significantly increased in the NST group compared to the pre-NST group (p=0.016, p=0.000, and p=0.000, respectively). The total period on antibiotic therapy was significantly decreased in the NST group compared to the pre-NST group (p=0.007). Conclusion: Because nutritional support by the pNST is of benefit to the clinical course of preterm infants in the NICU, the pNST should recommend to improve the nutritional status and clinical outcome of preterm infants.

The purpose of this study is to inquire into the effect on the coping with stress by the knowledge of Emerging infectious disease, clinical practice stress. A research was held to the nursing students living in Seoul and Chungbuk from September 10 to October 10, 2022, 259copies of the data were used for the final analysis, Pearson's correlation coefficient and Multiple linear regressions was used. As a result of the study, there was a positive correlation between clinical practice stress due to burden of work, practice education environment stress, and active coping with stress. Clinical practice stress due to interpersonal conflicts, conflicts with patients, burden of work, and undesirable role models was positively correlated with passive coping with stress. Satisfaction of clinical practice, practical educational environment stress and gender accounted for 15.0% of the total variance in the active stress coping, and burden of work accounted for 7% of the total variance in the passive stress coping. Consequently, this study could be suggested as a basis for counseling and developing practical education program for active coping with stress.

Purpose : We investigated clinical characteristics of real-time PCR proven EBV viremia patients who were not serologically diagnosed but clinically suspected, and compared it to serologically proven EBV infected patients. Methods : The study population consisted of 45 patients, who were suspected acute EBV infection at Wonju Christian Hospital Department of Pediatrics, Yonsei University Wonju College of Medicine from Jan. 2004 to Dec. 2006. real-time PCR of cell free serum was performed to prove EBV viremia. Then we chose $102.5copies/{\mu}g$ DNA as a suitable cutoff level for EBV associated diseases. Results : There are 4 patients diagnosed as EBV infection by serologically and 15 patients diagnosed as EBV viremia by real-time PCR quantitative measurement. The most common presenting symptoms and signs of EBV viremia was fever in 11 cases (73%). Atypical lymphocytosis was found in 4 cases (27%). Increased AST, ALT levels were observed in 13 cases (87%), 12 cases (80%), respectively. We could diagnose 5 cases of EBV viremia younger than one year of age. They revealed clinical symptoms which could be found in EBV infection. The serologically diagnosed patients had hepatomegaly and splenomegaly in 3 cases (75%). All serologically confirmed patients have leukocytosis above $20,000/mm^3$, among them 2 cases (50%) had higher percentage (>15%) of atypical lymphocytes. The AST/ALT level above 50 IU/L were demonstrated in all cases. Conclusion : Serologically unproven real-time PCR EBV viremia patients revealed similar clinical findings with that of serologically proven EBV infected patients. So, it is meaningful to perform EBV real-time PCR for the diagnosis of EBV infection especially for the cases younger than 1 year of age.
