Purpose : Dental trauma is frequently unpredictable. The initial assessment and urgent treatment are essential for dentists to save the patient's teeth. Mobile-phone-assisted teleconsultation and telediagnosis for dental trauma could be an aid when a dentist is not available. In the present in-vitro study, we evaluated the success rate and time to transfer images under various conditions. Materials and Methods : We analyzed the image quality of cameras built into mobile phones based on their resolution, autofocus, white-balance, and anti-movement functions. Results : The image quality of most built-in cameras was acceptable to perform the initial assessment, with the autofocus function being essential to obtain high-quality images. The transmission failure rate increased markedly when the image size exceeded 500 kB and the additional text messaging did not improve the success rate or the transmission time. Conclusion : Our optimal protocol could be useful for emergency programs running on the mobile phones.

Purpose: This study aimed to compare work-related musculoskeletal symptoms, occupational stress and nursing work environments of nurses working in patient-sitter wards and general wards. Methods: The study surveyed 240 nurses with more than one year of experience working in both patient-sitter wards and general wards. The collected data then was analyzed by SPSS statistics version 22. Results: As for the musculoskeletal symptoms, the survey showed that 85.2% and 67.8% of the nurses had such symptoms respectively in patient-sitter wards and general wards. In terms of occupational stress, no significant difference was observed between the patient-sitter ward and the general ward (t=-0.23, p=.821). Lastly, the study showed that there is a significant difference in terms of work environment considering the scores recorded 2.65 and 2.55 points respectively in patient-sitter ward and general ward (t=2.53, p=.012). Conclusion: Follow-up research should look at ways to lower the rate of experiencing work-related musculoskeletal symptoms; analyze work performances and establish work standards to lower occupational stress; and devise measures to improve the work environment for the nurses working in patient-sitter wards.

Malakoplakia is an uncommon chronic granulomatous inflammation that usually involves the urinary and gastrointestinal tracts, but rarely affects the female genital tract. We experienced a case of malakoplakia in a cervicovaginal smear in a 54-year-old woman. Colposcopic examination showed a friable, easily bleeding tissue in the uterine cervix and the vaginal fornix. The cervicovaginal smear consisted of numerous isolated histiocytes, polymorphonuclear leukocytes, lymphocytes, and plasma cells. The histiocytes had an abundant, granular, and degenerated cytoplasm with inflammatory cell debris. Michaelis-Gutmann bodies were readily identified.

Primary cutaneous anaplastic large cell lymphoma (C-ALCL) is a rare subtype of primary cutaneous lymphoma with a favorable prognosis. Primary cutaneous CD30+ lymphoproliferative disorders, which include C-ALCL and lymphomatoid papulosis, are the second most common group of cutaneous T-cell lymphomas. C-ALCL is comprised of large cells with anaplastic, pleomorphic, or immunoblastic cytomorphology, and indeed, more than 75% of the tumor cells express the CD30 antigen. C-ALCL clinically presents with solitary or localized reddish-brown nodules or tumors, and sometimes indurated papules, and they may be with ulceration covering with dark eschar. Multifocal lesions are seen in 20% of the patients. Extracutaneous dissemination, which mainly involves the regional lymph nodes, occurs in 10% of patients. A 69-year-old man noticed a mild elevated cutaneous lesion containing central ulceration covering with brownish black necrotic tissue on the right lower lip, and the lesion was surgically removed. After the first operation, another skin lesion was developed and the histological examination confirmed the diagnosis, C-ALCL. Eight specimens were excised during the 7-month follow-up period. The patient started the treatment with low-dose oral methotrexate (15 mg/wk) and there was no recurrence for 11 months.

Purpose: The purpose of this study was to identify needs of health education of the students, parents, general teachers, and health teacher of the elementary, middle, and high schools. Method: 279 schools of elementary, middle, and high school were sampled nonproportionally during the period from June 28 to July 26, 2004 The data were collected by the questionnaire from 1,888 students, 1,876 parents, 1,695 general teachers, 279 health teachers. A frequency, % and $x^2-test$ were used to analysis by SAS program. Result: 1. It showed that 98.1% of elementary school students, 92.3% of middle school students, 89.6% of high school students answered that they need health education. The most of students, parents, and general teachers had high interests in health education. 2. In the case of students, main causes of needs of health education was 'to prevent diseases or accidents'. But parents answered that it was 'to build up a healthier behavior'. General teachers answered that it was 'more effective systematic and continuous health education'. 3. Over 80% of students, parents, and general teachers about the question of who qualified person is to teach health education as a regular class responded that health teacher is available. Especially 93% of elementary school students answered like that. 4. The most of students, parents, and general teachers answered that health education in the classroom is favorable 1 to 2 hours per week. Conclusion: As results of the study, the majority of students, parents, general teachers agreed needs of health education. Therefore, on the basis of this study, systematic and continuous health education is necessary. Additionally the establishment of independent health subject is required certainly.

Objective: To explore the differential protein expression profile in EC304 gastric cancer cells induced by alphastatin. Methods: Cultured EC304 cells in the exponential phase of growth were randomly divided into alphastatin and control groups. Total proteins were extracted and the two dimensional electrophoresis (2-DE) technique was applied to analyze differences in expression with ImageMaster 2D Platinum 5.0 software. Proteins were identified using the MASCOT database and selected differently expressed proteins were characterised by western blotting and immunofluorescence. Results: $1350{\pm}90$ protein spots were detected by the ImageMaster software in the 2-DE gel images from the control and alphastatin groups. The match rate was about 72-80% for the spectrum profiles, with 29 significantly different protein spots being identified, 10 upregulated, 16 downregulated, two new and one lost. The MASCOT search scores were 64-666 and the peptide matching numbers were 3-27 with sequence coverage of 8-62%. Twenty-three proteins were checked by mass spectrometry, including decrease in Nm23 and profilin-2 isoform b associated with the regulation of actin multimerisation induced by extracellular signals. Conclusion: The proteome in EC304 cells is dramatically altered by alphastatin, which appears to play an important role in modulating cellular activity and anti-angiogenesis by regulating protein expression and signal transduction pathways through Nm23 and profilin-2 isoform b, providing new research directions for anti-angiogenic therapy of gastric cancer.

Purpose: The aim of this study was to test whether maternal uncertainty and the general characteristics of mothers and children influenced maternal coping. Methods: In this cross-sectional study, 190 mothers whose children had been admitted to the pediatric ward of a general hospital completed self-report questionnaires during their children's hospitalization. The questionnaires assessed the general characteristics of the mothers and children, maternal uncertainty, and maternal coping. Multiple regression analysis was used to test the research model. Results: In the multivariable model, help from one's spouse (t=3.10, p=.002), religion (t=2.68, p=.008), overall ambiguity (t=2.64, p=.009), and family income (t=2.33, p=.021) were associated with higher coping scores. Conclusion: This research model presents possible guidelines for pediatric nurses to provide comprehensive and accurate information on children's illnesses and treatments for mothers of children hospitalized in general hospitals. In particular, nurses should pay more attention to mothers who are not receiving help from their spouses, are not religious, and have a low family income.

The purpose of this study was to analyze the effects of comparative advertisement brand typicality and need for recognition in outdoor apparel market. This study was created with a mixed factorial design of 2 (Advertisement types: Comparative advertisement vs. General advertisement) X 2(Brand Typicality: High Brand vs. Low Brand) X 2 (Need for Cognition: High vs. Low). The results of this study are as follows: First, it was shown that comparative advertisement had a greater positive influence on attitudes toward advertising intentions in comparison to general advertisements. Second, while comparative advertisement was more effective than general advertisement for outdoor apparel brands with low typicality. Third, consumers with higher need for cognition showed a preferred attitude toward advertising intention when met with comparative advertising in contrast to general advertisement. Fourth, when consumers with higher needs for cognition were exposed to advertisement for brands of lower typicality, there was higher positive influence on the attitudes toward advertisement intention with comparative advertisement in comparison to general advertisement. This means the comparative advertisement may be effective for the new garment brand or the garment brands having low typicality to secure the cognition quickly from the consumers having high need for cognition.

Parkes Weber syndrome is a rare congenital vascular anomaly, related to the RAS p21 protein activator 1 (RASA1) gene. It is characterized by capillary cutaneous malformations, bony and soft tissue hyperplasia, and multiple arteriovenous fistulas throughout the affected upper or lower extremity. These arteriovenous fistulas can be associated with life-threatening complications such as bleeding, thrombosis, and high output heart failure. In this report, we present a neonate who had a disproportionately hypertrophied left upper limb with port-wine stain, dystrophy of the left humerus, and hypertrophy of the left clavicle on X-ray, and arteriovenous malformation and massive dilatation of the left subclavian artery on magnetic resonance angiography. Exome sequencing analysis revealed a novel heterozygous splicing mutation (c.1776+2T>A) in the RASA1 gene. To the best of our knowledge, this report is the first case of RASA1-related Parkes Weber syndrome in Korea.
