Malignant fibrous histiocytoma (MFH) of the liver is uncommon, representing less than 1% of the primary malignant lesions of the liver. We report primary MFH of the liver in a 59-year-old woman. The tumor, measuring 9.0 9.0 6.0 cm, was located in the left lobe of the liver. It showed multiple areas of hemorrhage and necrosis. Microscopically, the tumor consisted of plump spindle cells haphazardly arranged in short fascicle and focal storiform pattern. Multiple bizarre giant cells were also noted. Immunohistochemically, many of the tumor cells were positive for vimentin and alpha1-antitrypsin but negative for epithelial markers. Ultrastructurally, the tumor cells showed fibroblastic and histiocytic features.

PURPOSE: This study was done to analyze the relationship between organizational communication satisfaction and organizational commitment among hospital nurses. METHOD: A survey was conducted with 647 nurses who were working in 24 hospitals in Korea. Data were collected during August 2010. Data were analyzed using descriptive statistics, t-test, ANOVA, Pearson correlation analysis, and multiple regression. RESULTS: The mean level of organizational communication satisfaction was 3.15 (min 1.88 -max 4.88) and the mean level of organizational commitment was 3.21 (min 1.33 - max 4.83). There was a statistically significant correlation between organizational communication satisfaction and organizational commitment (r=. 655). According to analysis of the impact of the subconstructions of organizational communication satisfaction on organizational commitment, the following factors had significant influence on organizational communication satisfaction: vertical communication, communication media, and organizational climate. CONCLUSION: These findings showed that communication satisfaction was the most important factor for nurses' organizational commitment. Therefore, there is a need to develop communication strategies and skills for hospital nurses to increase the level of communication satisfaction.

STATEMENT OF PROBLEM: Recently the populations of patients receiving implant surgery are greatly increase for maintaining oral health. PURPOSE: This study was conducted for implanted patients to assess the chewing ability patient satisfaction level and changes in quality of life before and after the implant surgery. MATERIAL AND METHODS: The current study subjected 109 adult patients, older than 20 years of age, who received implant surgery from December, 2006 to October, 2007 at the 6 dental clinics located at Daegu and Ulsan metropolitan cities. Twice of surveys were conducted for the patients before and after receiving the dental implant surgery. RESULTS: As the motivation of receiving implant surgery, 45.9% of the patients selected the surgery for the chance of "chewing function recovery", and "failure of treatment and complications" was found to be the most worrisome at the time of surgery by recording 38.5%. The satisfaction level before the implant surgery scored 30.37, while the score was increased to 45.01 after the surgery by showing a significant difference before and after receiving the surgery (P < .001). Regard on the surgery, 91.8% of the patients responded as "Satisfy", and 89% of the study subjects responded that they have willingness to recommend the surgery to their families and friends. The chewing ability score measured by using the surveys on edible foods, the score before the surgery was 15.24, while the score was increased to 19.11 after the surgery by showing a significant difference before and after receiving the surgery (P < .001). The quality of life score was also found to be increased to 11.17 after the surgery from 9.99 before the surgery by showing a significant difference (P < .001). CONCLUSION: In a future, the studies on the numbers of implanted loss teeth and the location of tooth loss are necessary, more long-term follow study are needed, and it is thought to be necessary to enlarge the sample size of subjects in conducting the studies.

Purpose: The purpose of this study was to examine the effects of organizational socialization, perceived organizational vision, and attitude toward organizational change on organizational commitment of nurses working in one hospital. Methods: This study was conducted with 441 participants in a hospital in A city, South Korea from Nov. 1 to 30 2017.Data were analyzed using frequency, percentage, mean, standard deviation, t-test, ANOVA, Scheffé test, Pearson Correlation and Multiple Regression with the SPSS/WIN 23.0 program. Results: There were significant correlations among organizational socialization, perceived organizational vision, attitude toward organizational change and organizational commitment. The factors that significantly influenced organizational commitment were organizational socialization (β=.10 p=.015). perceived organizational vision (β=.20, p<.001), and attitude toward organizational change (β=.44, p<.001). These variables explained 50.0% of the variance in organizational commitment. Conclusion The findings indicates that organizational socialization, perceived organizational vision and attitude toward organizational change affect organizational commitment.

The Q-switched ruby laser has been used in clinics since the early 1980s. It was tried to remove tattoos at first with good effects. Thereafter, some physicians reported the usefulness of the laser in the treatment of some kinds of pigmented lesions such as nevus of Ota, freckles and lentigines. The reason why the Q-switched ruby laser has a lot of effect on tattoos and some pigmented lesions is that the laser has the function of selective photothermolysis on those cutaneous lesions. The authors have treated 185 patients with tattoos and cutaneous pigmented lesions using the Q-switched ruby laser during last 4 years ago. Patients had tattoos, nevus of Ota, freckles, lentigines, melasma, postinflammatory hyperpigmentation, and were followed up over 5 months after the end of the laser treatment. The authors analysed the results and compared them with other's results in Caucasians, and we intended to present a guide of the treatment using Q-switched ruby laser in Koreans. The results were as follows 1. Tattoos showed good results after the treatment because the most of tattoos are black or dark blue in color and cheated by amateur. We repeated the laser treatments with the interval of 2 weeks. 2. Nevus of Ota, freckles and lentigines showed good results after treatment of the Q-switched ruby laser 3. Melasma showed no improvement after the treatment. 4. The treatment of postinflammatory hyperpigmentation using the Q-switched ruby laser must be confined within a part of the lesion at the first visit of patient, because the therapeutic effects were observed in some patients only and the degree of depigmention after treatment was diverse. 5. The most common complication after Q-switched ruby laser treatment was pigmentary change, including hyperpigmentation in most of the cases and hypopigmentation in some cases. However, there was no visible scar or remarkable change of skin texture in all of the cases.

Benign hemangioma of the mediastinum is rare. This slowly growing tumor is described as well circumscribed, cystic, hemorrhagic tumor. Histologically it can be differentiated into capillary or cavernous form. We present a case of mediastinal hemangioma. A 20-year-old-man was presented with a slowly growing posterior mediastinal mass of 6 years duration, 8x6 cm in size. The mass was relatively well defined but focally invasive. Microscopically, it was differentiated into vessels of capillary, cavernous, and venous patterns. A solid cellular proliferation with inconspicuous capillary lumens was focally seen. The stroma between variable-sized vessels showed marked myxoid change associated with some smooth muscle bundles and adipose tissue. Ultrastructurally, areas of solid cellular proliferation showed formation of lumens. These lumens were lined by active endothelial cells showing plasmalemmal vesicles and Weibel-Palade bodies on the abluminal surface.

With the aim of establishing bio-indices for the development of multistep hepatotumorigenesis, rats were fed water containing 0.01% diethylnitrosamine (DEN) ad libitum for 13 weeks. This treatment with DEN only made it possible to induce hepatic tumors in 100%. After the DEN administration, several clinical symptoms were observed including minor behavioral changes, brittleness of hair and a decrease in water and food intake. The concentration of total serum protein and albumin in all treated groups was significantly lower than in non-treated controls (p<0.05). Increase of specific enzyme (AST, ALT and GGT) activity (p<0.05), variable tumor size and hepatomegaly of the liver was observed in all rats treated with DEN for 10 weeks. Both hepatocellular carcinoma and cholangiocarcinoma were found in the same livers at the same time, and were prominently developed after 12 weeks. In case of carcinoma, some of the livers showed more or less advanced states over the 12-15 weeks period. In the present study, hepatocellular carcinoma was developed by treating DEN in only the drinking water, without any other carcinogens or without partial hepatectomy. These results indicate that DEN is a new carcinogen that acts directly on it the liver, moreover, it might be very useful for investigating hepatotumorigenesis.

PURPOSE: As Korean society has rapidly become multicultural in the last few decades, it is essential for nurses to become culturally competent to provide effective care for ethnically and culturally diverse populations. Considering the advantages of standardized instrument, there is a need to evaluate current cultural competence instruments to assess adaptability to Korean nurses. METHODS: Using Macdowell's instrument evaluation guideline, a review and evaluation was done of the Inventory for Assessing the Process of Cultural Competence among Healthcare Professionals (IAPCC) and Cultural Competence Assessment (CCA), which were both developed based on cultural competence theoretical models and have been commonly used in nursing research. Two other Korean instruments were also evaluated. RESULTS: The instruments reviewed have limitations in reliability and validity, as well as cultural background and development process, for measurement of cultural competence in Korean nurses. CONCLUSION: The results of this study indicate that it is necessary to discuss and agree on a definition of what cultural competence is and to develop instruments to measure cultural competence in Korean nurses.

PURPOSE: The purpose of this study was to identify factors affecting the social distance between minority groups and nursing cadets. METHODS: A cross-sectional survey design was used. A questionnaire was distributed to the entire Armed Forces Nursing Academy cadets. Data from 273 nursing cadets were analyzed using t-test, ANOVA, Pearson correlation coefficients and Stepwise multiple regression. RESULTS: Social distance had positive correlations with collective identity (r=.28) and multiculturalism (r=.37). A negative correlation was found between social distance and perceived threat (r=-.38). Perceived threat, multiculturalism, collective identity, and frequency of contact with minorities were identified as factors affecting the social distance. The model explained 24% of the variables. CONCLUSION: To effectively respond to the minority groups' nursing needs in the army, educational programs which help to reduce the perceived threat, to strengthen multiculturalism, and to establish a healthy collective identity of nursing cadets need to be developed.
