PURPOSE: This study was done to develop a video discharge education program focusing on mother-infant interaction to facilitate the development of maternal role confidence for mothers of premature infants. METHODS: The process of the program was based on the Network-based Instructional System Design suggested by Jung (1999). For the content of the program, needs and concerns of mothers of premature infants found on web sites and existing literature were analyzed. Based on this content, the scenario and the video were developed. Nurses and mothers of premature infants participated in the process of testing the content validity, scenario development, and evaluation of final video production. The final video has two parts and lasts 21 minutes. The first part focuses on mother-premature infant interaction and the second part focuses on health management of infants. RESULTS: Eleven mothers of premature infants participated in the evaluation of the appropriateness of the video as a teaching method and for educational content. They reported that the content on mother-infant interaction, maternal sensitivity, and maternal role confidence was especially beneficial. CONCLUSION: The findings indicate that video program is effective for education on maternal-premature infant interaction and the use of video in practical settings is strongly recommended.

PURPOSE: The aim of this study was to identify historical backdrop leading to the introduction of the doctorate degree of nursing in Korea, and to explore trends of doctoral nursing education program. METHODS: The research design was a descriptive study adopting a historical approach. Documentation data were collected through web sites and mail survey. The semi-structured interviews were conducted with 6 professors who were involved in the introduction of the doctorate degree of nursing. The outcomes of doctoral nursing education program were evaluated with a total of 1,153 dissertations' titles published from 1982 to 2007. RESULTS: First introduced in Korea in 1978, doctoral nursing education program had steadily increased totaling 21 doctoral program in 2007. This resulted in a rapid increase in the number of doctoral students, but the number of faculty and the quality were not as satisfactory as expected. Many doctoral program had the missions or goals that fostered nursing scholars, theorists, and researchers, a trend that seems set to continue. The majority of dissertations utilized the experimental design (39.9%), others were qualitative design (21.6%), and survey design (19.0%). CONCLUSION: Doctoral education that is the hallmark of nursing scholarship is further elaborated in terms of academic tradition of nursing school in Korea.

Appetite controlling has been an main strategy for regulating food intake and energy balance in obesity treatment. The aim of this study was to examine the effects of drinking tea of the medicinal herbs, fennel and fenugreek, on the subjective appetite in overweight Korean women. The study was conducted using a placebo-controlled, single-blinded, randomized, and 3-way crossover design. Nine healthy women were given fennel tea (FT), fenugreek tea (FGT), or placebo tea (PT). After drinking a given tea, a lunch buffet was provided and then food consumption of subjects was analyzed. Subjective appetite, hunger, fullness, desire to eat, and prospective food consumption were measured at seven independent time point using a visual analog scale (VAS). Mean age of 9 subjects were 49.7 +/- 4.5 years and their mean body mass index were 24.6 +/- 0.6 kg/m2. There was no significant difference in food consumption in the lunch buffet after drinking each tea; however, with respect to the subjective appetite scale, FGT decreased hunger, led to less prospective food consumption, and increased feelings of fullness compared with the PT (p < 0.05). Similarly, the consumption of FT resulted in decreased hunger, less prospective food consumption, and increased feelings of fullness compared with the PT (p < 0.05). The area under the curve of VAS graph indicated that FGT resulted in a higher feeling of fullness than the PT (p < 0.05). In conclusion, drinking the FT and FGT were significantly effective aid to suppress subjective appetite among overweight women in South Korea.

PURPOSE: This study focused on analysing costs per home health care nursing visit based on home health care nursing activities in medical institutes. METHOD: The data was collected in three stages. First, the cost elements of home health care nursing services were collected and 31 home care nurses participated. Second, the workload and caseload of home care nursing activities were measured by the Easley-Storfjell Instrument(1997). Third, the opinions on improving the home health care nursing reimbursement system were collected by a nation-wide mailing survey from a total of 125 home care agencies. RESULT: The cost of home health care nursing per visit was calculated as 50,626 won. This was composed of a basic visiting fee of 35,090 won (about 35 dollars) and travel fee of 15,536 won (about 15 dollars). The major problems of the home care nursing payment system were the low level of the cost per visit, no distinction between first visit and revisits, and the limitations in health insurance coverage for home health care nursing services. CONCLUSION: This study's results will contribute as a baseline for establishing policies for improvement of the home health care nursing cost and for applying a community-based visiting nursing service cost.

PURPOSE: The purpose of this study was to investigate in-depth and to understand the experience of people living with HIV who work as caregivers for patients with AIDS. METHODS: Data were collected from December 2010 to April 2011 through focus group and in-depth interviews. Ten people with HIV who work as caregivers for patients with AIDS participated in the research. Data were analyzed using Colaizzi's method (1978). RESULTS: The results showed the important themes to be 'feelings of sympathy', 'burden of caregiving', 'identifying one's own self-worth' and 'hoping for a meaningful future'. People with HIV experienced deep empathy with patients with AIDS, and, even though they suffered physical and emotional distress from the caregiving process, they felt a sense of self-worth and found their existence connected with the world. Furthermore, they were taking more active care of themselves and hoping for a meaningful future. CONCLUSION: For successful social adaptation of people with HIV currently in job-seeking activities, various vocational rehabilitation services are necessary. The results of this study could be used in developing effective social support services for people living with HIV attempting workforce re-entry.

IgG4-related disease (IgG4-RD) is a new disease entity characterized by elevated serum IgG4 and infiltration of IgG4+ plasma cells in tissue. IgG4-RD can involve various organs, and skin could also be affected. The manifestations of IgG4-related skin disease (IgG4-RSD) are not characteristic, however it usually presents with multiple erythematous nodules or plaques with itching sensation. We report two cases of IgG4-RSD. Histological studies of these cases revealed infiltration of numerous plasma cells and mononuclear cells in the entire dermis. Some plasma cells were strongly positive for IgG4 stain. IgG4-RSD is a treatable disease with systemic corticosteroids. Thus, clinicians should obtain a biopsy and identify IgG4-positive cells for an accurate diagnosis.

Colonic angiosarcoma is an extremely rare and aggressive malignant tumor with poor prognosis. We report a case of colonic epithelioid angiosarcoma with colonic obstruction and rapidly progressive hepatic metastasis in a 44-year-old female. Abdominal CT revealed a heterogeneously enhancing irregular mass in the ascending colon, causing proximal bowel distension. The patient underwent surgery, and histopathological examination revealed a poorly differentiated carcinoma. A follow-up liver dynamic MRI after 4 months revealed newly developed diffusely scattered numerous small nodules in both hepatic lobes with peripheral and nodular marked arterial hyperenhancement, raising the suspicion of hepatic angiosarcoma. A pathologic second opinion was obtained, and additional immunohistochemistry revealed colonic epithelioid angiosarcoma. The patient showed progressive hepatic metastasis on follow-up abdominal CT after 6 months and died 8 months after initial diagnosis. We describe an educational case of colonic angiosarcoma, a rare malignant tumor, with rapidly progressive hepatic metastasis that showed radiologic findings suggestive of angiosarcoma and enabled a re-diagnosis for proper treatment and prognosis prediction.

Background and Objectives: Ambient particulate matter (PM) in real urban air pollution (RUA) is an environmental health risk factor associated with increased cardiac events. This study investigated the threshold level to induce arrhythmia, as well as arrhythmogenic mechanism of RUA that mainly consisted of PM <2.5 μm in aerodynamic diameter close to ultrafine particles. Methods: RUA was artificially produced by a lately developed pyrolysis based RUA generator.C57BL/6 mice were divided into 4 groups: a control group (control, n=12) and three groups with exposure to RUA with the concentration of 200 µg/㎥ (n=12), 400 µg/㎥ (n=12), and 800 µg/㎥ (n=12). Mice were exposed to RUA at each concentration for 8 hr/day and 5 day/week to mimic ordinary human activity during 3 weeks. Results: The QRS and QTc intervals, as well as intracellular Ca2+ duration, apicobasal action potential duration (APD) gradient, fibrosis, and inflammation of left ventricle of mouse hearts were increased dose-dependently with the increase of RUA concentration, and significantly increased at RUA concentration of 400 µg/㎥ compared to control (all p<0.001). In mice exposed to RUA concentration of 800 µg/㎥ , spontaneous ventricular arrhythmia was observed in 42%, with significant increase of inflammatory markers, phosphorylated Ca2+ /calmodulindependent protein kinase II (CaMKII), and phospholamban (PLB) compared to control. Conclusions RUA could induce electrophysiological changes such as APD and QT prolongation, fibrosis, and inflammation dose-dependently, with significant increase of ventricular arrhythmia at the concentration of 400 µg/㎥ . RUA concentration of 800 µg/㎥ increased phosphorylation of CaMKII and PLB.
