This study was carried out to investigate the perception on nutrition labeling of the processed foods among elementary school teachers in Busan. The survey was conducted from November 1 to November 30, 2008 by questionnaires and data which were analyzed by SPSS program. The results are summarized as follows. Ninety five point seven percent of the male teachers and 98.2% of the female teachers recognized the nutrition labeling (NL). The necessity of a NL system and comprehension of NL were higher in the female group than the male group. NL was trusted by 22.9% of male teachers and 19.7% of female teachers. The main reason for checking NL of the teachers was for food safety. For the most important NL items at purchasing the food, the teachers replied 'trans fatty acid' and 'cholesterol'. Five point seven percent of male teachers and 17.0% of female teachers were educated for NL. Seventy two point nine percent of males and 91.0% of females recognized the necessity of NL teaching. It is necessary to prepare education programs for both teachers and students about accurate recognition of NL.

Peripheral T-cell lymphoma is the generic group given to a family of tumors composed of neoplastic lymphocytes with phenotypic features of peripheral T-cells. Certain peripheral T-cell lymphomas develop a hemophagocytic syndrome that mimics malignant histiocytosis, both clinically and pathologically. We experienced a case of nasal T-cell lymphoma, histologically mimicking malignant histiocytosis in a 40-year-old male. The chief complaints were nasal obstruction and intermittent mild fever. Mild anemia, elevated SGOT and SGPT, polyclonal gammophthy, and moderate hepatomegaly were present. Two weeks later was present an enlarged cervical lymph node. The biopsied nasal mass showed angiocentric and angiodestructive peripheral T-cell lymphoma withextensive necrosis and marked erythrophagocytosis by non-neoplastic histiocytes. Subsequently, cervical lymph node was biopsied, which showed peripheral T-cell ltmphoma with extensive necrosis and erythrophagocytosis as well. The atypical lymphoid cells revealed pan-T(+), but CD4(-) and CD8(-), whereas the reactive histiocytes showed lysozyme(+), immunohistochemistry.

Rosai-Dorfman disease (RDD) is a rare type of benign histiocytosis characterized histologically by intracellular engulfment of lymphocytes. Extranodal RDD may occur as a part of generalized process involving lymph nodes or may involve extranodal sites independent of the lymph node status. We have experienced a case of extranodal Rosai-Dorfman disease of the nose as an initial lesion prior to nodal involvement. The patient was a 20-year-old woman who complained of nasal obstruction for 4 years, remotely, and left submandibular mass for 3 months, recently. Histologically, the lesion taken from nasal cavity, submandibular gland and left upper jugular lymph node all showed an heavy infiltrate consisted of plasma cells, lymphocytes and sheets of macrophages with abundant pale cytoplasm, which replaced organ architecture. The associated focal fibrosis made it difficult to differentiate from inflammatory pseudotumor. Some macrophages demonstrated phagocytosis of lymphocytes, plasma cells and occasionally neutrophils. The macrophages were strongly positive for S-100 protein.

To search biologic characteristics of gastric carcinoma, one of the most common cancer in Korea, the author examined the alterations in DNA level and the expression of Ha-ras gene and c-myc gene in 20 primary tumors. Amplification of c-Ha-ras DNA was detected in 4(40%) of 10 patients who showed histologic subtype of relatively differentiated adenocarcinoma, but rearrangement of c-Ha-ras DNA was absent. Neither augumentation nor deletion of the c-myc DNA was observed. Higher expression of the ras p21 in tumor cells was noted in more differentiated tumor cells rather than poorly differentiated cases. One mucinous carcinoma, two signet ring cell carcinomas and one papillary carcinoma did not disclose expression of p21. The expressions of c-myc oncogene product were variable and were not correspond to the expressions of ras p21. A tendency that poorly differentiated tumor cells had higher expression of c-myc oncogene was suggested.

BACKGROUND: Nurses are often exposed to needlestick and sharp-object injuries (NSIs). This study aimed to investigate the post-exposure reporting rate of NSIs among nurses. METHODS: The subjects were 84 nurses from 4 hospitals (3 hospitals with 300 or more beds and 1 hospital with less than 300 beds) who had experienced at least 1 NSI within a 6-month period. The instrument was a self-administered questionnaire, which was based on the EPINet report form and a questionnaire for NSIs among resident physicians, which was used by Choi et al. Data were collected between April 9 and June 15, 2009, and analyzed using descriptive statistics and the chi-square test, which was performed using SPSS with a significance level of 0.05. RESULTS: Among the 84 nurses who had experienced at least 1 NSI within 6 months, only 14.3% had reported the NSIs, and 58.4% of these subjects reported the NSI immediately after sustaining the injury. The most common reason for not reporting was "the patients were found out to be uninfectious" (81.9%) followed by "too busy" (65.3%). The incidence of post-exposure reporting was negatively related to the number of NSIs (chi-square=13.871, p<0.001) and positively related to assessments of infectivity of the patients (chi-square=4.248, P=0.039) and other persons' recommendations to report NSIs (chi-square=4.092, P=0.043). CONCLUSION: The post-exposure reporting rate was very low. The factors responsible for this low rate should be investigated in a more systematic manner, and more measures should be undertaken to increase the reporting rate among nurses.

BACKGROUND: This study aimed to identify the effects of a multifaceted needlestick injury (NSI) prevention program on changes in knowledge about bloodborne infectious diseases and postexposure coping, attitudes toward postexposure reporting, preventive measures, the number of NSIs, and postexposure reporting pre- and post-intervention among nurses. METHODS: A total of 429 and 420 nurses participated in the pre- and post-intervention periods, respectively. The intervention was performed from April to September 2007, comprising NSI guideline education, the use of containers with enhanced engineering, and the supply of safety devices. RESULTS: The average score of knowledge about bloodborne infectious diseases increased significantly from 8.3 to 8.9 out of 14 points (P<0.001), but the change in score of knowledge about postexposure coping was insignificant. The average score of attitude toward postexposure reporting increased significantly from 8.9 to 9.6 out of 12 points (P<0.001). Preventive measures such as "gloves are provided whenever needed" (P<0.001), "use one-hand technique" (P<0.001), and "needle containers are provided whenever needed" (P=0.031) increased significantly. The number of NSIs decreased by 40.4%, and the postexposure reporting rate increased by 552.8%. CONCLUSION: The multifaceted NSI prevention program positively affected knowledge about infectious diseases and postexposure coping, attitudes toward postexposure reporting, preventive measures, the number of NSIs, and postexposure reporting after intervention. Therefore, we recommend that this program be applied to various healthcare workers in hospitals.

An immunohistochemical stain for p53 tumor suppressor gene product was performed in 59 primary lung cancers to study the relation between its expression and type of the tumor, degree of tumor differentiation,clinical stage and smoking. The results were as follows: 1. The expression of mutant p53 protein was noted in 28 of 59 cases(47.5%) of primary lung cancers. The p53 protein was expressed in 21 of 35(60%) squamous cell carcinomas, in 6 of 21(28.6%) adenocarcinomas, and 1 of 1(100%) small cell carcinoma. There was a significant difference in expression of p53 among the different histologic types of lung cancer(p<0.05). 2. The incidence of p53 protein expression did not correlate with the degree of tumor cell differentiation or the clinical stage of lung carcinoma(p>0.05). 3. The incidence of p53 protein expression was higher in smokers(current: 75%, former: 46.2%) than in non-smokers(5.6%) and was increased in direct proportion to the pack years. There was a statistically significant correlation between p53 expression and smoking(p<0.05). The mutation of p53 gene may often be an early event in the development of lung cancer and it is suggested that the smoking known as a risk factor for the development of the lung cancer may be associated with the transformation of p53 tumor suppressor gene into mutant p53 gene or oncogene.

This study was performed to evaluate effect on color and opacity of 3 different copy-milled In-Ceram cores by glass infiltration and porcelain veneering. Color was evaluated by the CIEL*a*b* readings were recorded with a Colorimeter, Color difference value( E*ab) was calculated and opacity was represented by the contrast ratio. The variance of each color parameter (L*, a*, b*), color difference value, and opacity change after glass-infiltrated and veneered with porcelain was compared. Three experimental groups were fabricated as follows. Group 1 (Alumina core) : 15 Alumina blanks was infiltrated with originally marketed glass (A1) and veneered with porcelain(A1) Group 2 (modified Alumina core) : 15 Alumina blanks was infiltrated with its associated glass(S11) and veneered with porcelain(A1) Groups 3 (Spinell core) : 15 Spinell blanks was infiltrated with originally developed glass(S11) and veneered with porcelain(A1) The results were as follows: 1. After glass infiltration, L* value showed decrease, a* value showed decrease only group 1(p<0.001) and b* value showed increase on group 1, increase on group 1, increase on group 2, 3(p<0.001). 2. After porcelain veneering L* value showed decrease(p<0.001), a* value showed increase on group 1, decrease on group 2(p<0.05) and b* value showed decrease on group 1, increase on group 2, 3(p<0.001). 3. E* ab between before and after galss infiltration was more than 13.77, and between after glass infiltration and after porcelain veneering more than 19.63. 4. After glass infiltration and porcelain veneering, Alumina showed the lowest L*, a* value and highest b* value among 3 different groups (p<0.05). E*ab between group 1-2, 1-3 was higher than that of group 2-3. 5. After glass infiltation, opacity showed decrease, Group 1 had the highest opacity(p<0.05), but no significant differences between group 2 and 3. Above results suggest that glass infiltration and porcelain veneering effects on color and opacity of In-Cream core, and that modified In-Ceram Alumina uses single crowns of bridges like In-Cream Spinell.

The purpose of this study was to identify the effects of phase 1 cardiac rehabilitation nursing care on cardiac rehabilitation knowledge, anxiety, and self-care behavior in patients with acture myocardial infarction. The study design was composed of a nonequivalent control group non-synchronized design and a non-equivalent control group post-test design. The subjects of the study consisted of thirty-four acute myocardial infarction patients hospitalized at a university hospital in Taegu between February 16, 1998 and May 12, 1998. the 34 research subjects were assigned to experimental( 17 patients ) and control( 17 patients ) groups. The phase 1 cardiac rehabilitation nursing care was composed of cardiac rehabilitation education taken from a rehabilitation manual and booklet, and participating in a progressive exercise program. After discharge, a phone interview was conducted in order to encourage the self-care behavior. The modified Knowledge Scale developed by Rahe et al.(1975) and translated into Korean by Hwang(1986), and the modified Self-Care Scale of exercise and diet based on Hickey et al.(1992), were used for data collection. Analysis of data was done by use of Chi-square test, t-test, Repeated measure ANOVA, Simple Main Effect, and Time contrast. The results of this study are as follows : 1. The first hypothesis, "The experimental group which received the phase 1 cardiac rehabilitation nursing care will have a higher level of knowledge than the control group", was supported(F=24.07, p=.000). 3. The third hypothesis, "The experimental group which received the phase 1 cardiac rehabilitation nursing care will have higher self-care behavior scores than the control group", was supported( t=-15.49, p=.000 ). From the above results, it can be concluded that phase 1 cardiac rehabilitation nursing care is an effective nursing intervention knowledge, reducing anxiety, and improving self-care behavior in patients with acute myocardial infarction.
