The purpose of the study was to test the reliability and validity of the Korean version of Children's Health Locus of Control Scale(CHLC), an instrument designed to measure health locus of control in children aged 7 to 12. The scale was administered to 467 children in grades 4 to 6, enrolled in 2 elementary schools located in city. The mean age of the subject was 10.03(SD=1.33). The findings were as follows: 1. Cronbach alpha coefficient for internal consistency was .69 for the total, and .67, .65, and .56 on the respective subscales. 2. Construct validity was supported through factorial isolation of three theory consistent subscales: internal, chance, and powerful others. Two items did not fit well with the originally developed subscale. The total percent of variance explained by 3 factors was 34.5%. The result of the factor analysis according to Kaiser's criterion revealed that the scale was consisted of 5 factors. But, The items of the subscales were rather inconsistent with the dimensions of the locus of control concept. 3. There were significant differences according to parent's educational level and occupation, and birth order on the scores of the CHLC. There were no significant differences according to grade level and sex. 4. The score of the CHLC was significantly correlated with the self concept of the children(r=.14, p<.001). The result indicated that the Korean version of Children's Health Locus of Control Scale was valid and reliable in measuring health locus of control concept in children, even though further research is required to reconfirm and increase the reliability of the instrument. CHLC could be used for study explaining the health related behavior of the children and research project to health education program.

Blood utilization review has recently been used to minimize inappropriate transfusion, reduce post transfusion infections and improve the quality of transfusion practices. Ajou University Hospital is a 906 bed tertiary care teaching institution. Since March, 1995, the concurrent review of blood transfusion requests using institutional blood transfusion criteria has been initiated. To evaluate the effectiveness of the transfusion review, the units of blood components transfused per patient(total number of units of blood components transfused/total number of patients discharged) and inappropriate transfusion ratio of blood components(total number of units of blood components inappropriately transfused/total number of units of blood components transfused) were compared during the concurrent review for 9 months and pre-concurrent review for 9 months, respectively. The possible savings of blood components realized by the review were also extrapolated. The results were as follows : 1. The unit transfused per patient for pre-review and during review were 0.675 (9,080/ 13,422) and 0.654(12,123/18,546) for packed RBC(PRBC); 0.417 (5,602/ 13,422) and 0.296 (5,444/18,546) for fresh frozen plasma(FFP); 0.372(5,007/13,422) and 0.424(7,868/18,546) for platelet con-centrates(PC), respectively. 2. The inappropriate transfusion ratio of blood components for pre-review and during review were 0.039 and 0.009 for PRBC; 0.321 and 0.064 for FFP; 0.143 and 0.008 for PC, respectively. These differences were statistically significant(p=0.000). 3. The PRBC and FFP anticipated to have been saved by this review was 519 units and 2,992 units annually, respectively. 4. However, 2,621 units of PC were used additionaly during this review due to increased number of oncology patients and better hemostatic therapy practiced during the same period. In conclusion, the concurrent review of transfusion requests was very effective tool to educate residents in clinical departments the transfusion medicine and improve utilization of blood and its components.

PURPOSE: The purpose of this study was to evaluate the learning experience, knowledge, and performance of cardiopulmonary resuscitation (CPR) in newly graduated nurses, and to identify differences related to learning experience. METHODS: The participants were 114 new nurses in the hospital. They were asked to complete a questionnaire, which included CPR learning experience. They were evaluated by a written test and a skill test using a manikin and check list. RESULTS: All participants attended CPR lectures and underwent practice while in university. Only 12.28% of participants were taught by a certified Basic Life Support (BLS) instructor. The mean scores of the written and skill tests were 79.82+/-12.69 and 64.41+/-11.71, respectively. The nurses lacked CPR knowledge related to checking breathing, the frequency of 30 chest compressions, compression rate, and automated external defibrillator use. They also lacked skill in performing CPR related to checking breathing and pulse and giving 2 breaths. CPR performance differed according to learning time (p=.047) and BLS educator (p=.029). CONCLUSION: The findings of this study reveal that CPR performance by newly graduated nurses is poor and suggest that CPR education by trained instructors, practice-based education, and reeducation programs must be provided to newly graduated nurses in the hospital.

PURPOSE: The purpose of this study is to find some points that may help the differential diagnosis of ring lesions in magnetic resonance (MR) imaging of the liver through recognition of the characteristics of the morphology and the signal intensities of the ring lesions. MATERIALS AND METHODS: T1- and T2-weighted axial spin-echo images and gadolinium-enhanced Tl-weighted images were obtained with a 1.0 T superconducting MR imager. We reviewed the MR findings of 23 hepatic ring lesions which were confirmed as hepatocellular carcinomas (13), metastases (4), liver abscesses (4), hydatid cyst (1), and hematoma (1). RESULTS: There were 19 single rings and 4 double rings (all the cases were liver abscesses) on Tl-weighted images, and 8 single rings and 14 double rings on T2-weighted images. The signal intensity of the ring was low in hepatocellular carcinoma on Tl-weighted images and in hydatid cyst on T2-weighted images. It was high on Tl-weighted images in subacute hemaroma. Target lesion as an inner high-signal-intensity ring surrounded by a high-signal-intensity ring on T2-weighted images was seen in metatasis, liver abscess, and hepatocellular carcinoma. CONCLUSION: It is helpful to recognize the chracteristics of morphology and signal intensities of the ring lesions in the differential diagnosis of hepatic focal lesions.

PURPOSE: The purpose of this study was to identify the process of overcoming the intention toward turnover experienced by career nurses. METHODS: Data were collected from 10 career nurses though in-depth interviews about their experiences. The main question was "How do you describe your experience of the process of overcoming intention to turnover as a career nurse?" Qualitative data from field and transcribed notes were analyzed using Strauss & Corbin's grounded theory methodology. RESULTS: From the participants' statement, 127 concepts, 34 subcategories and 13 categories were extracted through the open coding process. The core category was discovered to be 'back to the original place'. Phenomenon was identified as 'reached the threshold that cannot be withstood' and this series of process was categorized as having four stages: 'conflict', 'meditation', 'discovery' and 'conquest'. There were three types of overcoming turnover intention in career nurses, 'adjustment', 'compromise', 'self-led'. CONCLUSION: The results of this study produced useful information about the needs of career nurses during the process of overcoming turnover intention based on their stage and overcoming types of turnover intension. Ultimately this study may help decrease the turnover intention of career nurses.

Systemic lupus erythematosus, an autoimmune disease with multisystem involvement, has been reported to be associated with a number of gastrointestinal complications and symptoms such as nausea, vomiting, and abdominal pain. However, acute pancreatitis only rarely has been reported as a complication of SLE. We report a case of SLE presenting drug unrelated acute pancreatitis as a initial manifestation.

BACKGROUND: HLA-B40 is the most frequently identified HLA-B type in Koreans. Also HLA-B60 and B61 are the serologic split antigens of HLA-B40. But because of the lack of mono-specific alloantisera, cross reactivity of sera used as typing reagents, and poor antigenicity of some specific cells such as cord blood lymphocytes, discrimination between HLA-B60 and B61 has been often problematic in laboratories. In this study, authors evaluated whether the PCR-SSP method can be useful for accurate assignments of HLA-B60 and B61 or not. METHODS: Twenty-nine lymphocytes samples which were suspected as heterozygotes or homozygotes of HLA-B60 or B61 and three samples typed as HLA-B40 are selected from stored cord blood and organ transplantation donors. HLA types of these samples were defined by serologic method using a commercial typing kit. PCR that amplified exons 2 and 3 of the HLA-B gene using sequence specific primer pairs exactly matched to HLA-B60 or B61 allele making up a serological specificity was done. RESULTS: A clear discrimination between B60 and B61 was possible in all samples including 9 serologically ambiguous samples. Discrepancy between serologic typing and molecular typing was seen in three cases identified serologically as B40 positive but inable to define a split. Among three samples, two were identified as HLA-B61 and one was identified as HLA-B60. CONCLUSIONS: Molecular typing was useful in discriminating between HLA-B60 and B61. The PCR-SSP method for HLA-B60 and B61 including other cross-reactive HLA types will be helpful as a supplemental method of the serologic typing.
