PURPOSE: The purpose of this qualitative study was to explore the experience of becoming a mother after child-birth of Chinese immigrant women in Korea. METHODS: Ten Chinese immigrant women were recruited from multi-cultural center in the metropolitan area. Qualitative data were collected through in-depth interview from July 2015 to May in 2016. Interview was conducted until the data were theoretically saturated. Data analysis was performed simultaneously with the data collection, and the contents of the interview were analyzed according to the Corbin and Strauss' grounded theory method. RESULTS: In total, 36 concepts were produced through the analysis, and similar concepts were combined to derive 16 categories. Based on the relation between the categories, the core category is analysed as ‘becoming culture integrating mothers’. The attainment process from this procedural approach are described as cultural intimidated stage, cultural conflicting stage, cultural cooperating stage, cultural integrating stage. There are three types of ‘becoming cultural integrating mothers’, integrating type, conflicting type, and intimidated type. CONCLUSION: Based on these results, it is suggested to develop the nursing intervention program including cultural sensitive education and consultation program for helping becoming a mother in each type of the Chinese immigrant women in Korea. In addition, nurse or nursing student education program to enhance the cultural sensitivity is also needed.

PURPOSE: This study aimed to describe knowledge status of current research related to maternal adaptation of women immigrants by marriage in Korea. METHODS: Eighteen quantitative current researches published from January, 2006 to August, 2014 that met the inclusion and exclusion criteria. These 18 articles finally selected for systemic review from 5,168 articles. All current researches included the mother within one year after childbirth and one variable related to maternal adaptation at least. RESULTS: Variables related to psychological adaptation (48.1%) were mostly studied. In detail, parenting stress (17.3%) and parenting competency (15.4%) were frequently surveyed. Also, social support (7.7%), husband rearing support (5.8%) of relational adaptation, and acculturation (3.8%) of cultural adaptation were importantly studied. In addition, frequently used instruments for each study variable were analyzed and evaluated. As major results, parenting stress and parenting efficacy were significantly influenced by social support or husband rearing support and acculturation, and had an effect on parenting behaviors. Various maternal education programs were effective in improving maternal role confidence or parenting efficacy and decreasing parenting stress. CONCLUSION: Nursing intervention programs for improving maternal adaptation should focus on decreasing parenting stress and increasing parenting efficacy by improving social support and acculturation level of women immigrants by marriage in Korea.

PURPOSE: This study was to explore the postnatal care experiences among first time Chinese immigrant mothers living in Korea. METHODS: Data were collected by focus group interviews with 12 first time Chinese immigrant mothers utilizing 3 focus groups. After obtaining written informed consent from all participants, each session of the focus group was audio-recorded and transcribed verbatim. Data were analyzed by content analysis to identify major themes. RESULTS: Four major themes for postnatal care experiences were extracted from the data as follows. 1) Range over traditional, modern, Korean or Chinese postnatal care, 2) Struggle with newborn care, 3) Another struggle with breastfeeding, and 4) Difficulties in becoming a mother as an immigrant. CONCLUSION: Based on their postpartum care experiences, it is concluded that participants requested more professional practical and individualized education/training for successful breastfeeding and newborn care. Health care providers need to develop and implement integrated support and mentoring programs that include information and peer support system for the first time Chinese immigrant mothers living in Korea. This would decrease the difficulties of becoming a mother.

Myxoid and round cell liposarcoma is a variant of liposarcoma characterized by a morphologic continuum in which tumor progression from low-grade myxoid to high-grade hypercellular or round cell areas may be observed. A 28-year old man presented with a painful skin colored subcutaneous mass on his left flank. The skin lesion was discovered about two months ago. Computed tomography revealed a well-defined tumor in the subcutaneous area without significant lymphadenopathy. A histopathologic study showed a nonencapsulated nodular growing tumor mass under the deep dermis composed of a mixture of atypical proliferating lipoblasts in a prominent myxoid stroma, occasional uniform round to oval shaped primitive nonlipogenic mesenchymal cells and plexiform, chicken wire shaped capillaries. Based on these findings, we diagnosed this case as myxoid and round cell liposarcoma. Because liposarcomas are large tumors of the deep subcutis or deeper soft tissue, they rarely come to the attention of the dermatologist. However, liposarcoma should be of concern, especially when rapid growing subcutaneous tumors are shown.

PURPOSE: IL-10 and IFN-gamma are amongst important cytokines, which are thought to have influence on organ transplantation outcome. The aim of this study was to investigate the IL-10 and IFN-gamma gene polymorphisms in Koreans, and their association with renal transplantation outcome. METHODS: Three SNP sites (-1082 G/A, -819 C/T, -592 C/A) of IL-10 promoter region and CA repeats in intron 1 of IFN-gamma gene were analyzed using PCR-single strand conformation polymorphism (SSCP) and direct sequencing methods in 73 controls and 164 kidney allograft recipients. Association between polymorphisms of these genes and transplantation outcome was analyzed using chi square test or Fisher's exact test. RESULTS: The allele frequencies of the IL-10 and IFN-gamma genes showed no significant differences between the control and patient groups. The frequencies of IL-10 and IFN-gamma high producer alleles were markedly lower than those of Caucasians. The incidence of multiple acute rejection episodes was higher in IL-10low producer (-1082 AA) than intermediate producer (-1082 GA) group (8.6% vs 0%), and in IFN-gamma high producer ([CA]12 positive) than low producer ([CA]12 negative) group (11.9% vs 6.6%). The incidence of chronic renal allograft dysfunction was lower in IL-10 intermediate producer than low producer group (7.7% vs 18.0%), and also lower in the combination of IL-10 intermediate/IFN-gamma low producer type than in other combinations (0% vs 18.2%). However, all these differences were not statistically significant. CONCLUSION: IL-10 and IFN-gamma have little influence on renal transplantation outcome in Koreans, probably due to quite limited polymorphisms of these genes in this population. The results of this study would be useful as basic data for renal transplantation in Koreans.

OBJECTIVES: The purpose of this study was to explore the influence of high school students' mental health on their academic achievement and school dropout rate by using longitudinal data. METHODS: For this study, 153 high schools were randomly sampled on a nationwide scale. The descriptive data was collected from a school information internet site which is organized by the Korean Ministry of Education. We used the schools' mean scores on the Adolescent Mental Health Problem-Behavior Questionnaire-II (AMPQ-II) scale which was used for estimating students' mental health in the 2013 school-based mental health screening test. The data analysis was conducted by using hierarchical regression analysis. RESULTS: The results of this study showed that the AMPQ-II scale's mean scores have significant effects on the following year's academic achievement and annual dropout rates. Especially, the AMPQ-II scale's mean scores tend to increase the school dropout rate in vocational schools. CONCLUSION: The finding of this study is that Korean high school students' mental health states significantly influence their academic achievement and school dropout rate.

BACKGROUND/AIMS: The shortage of cadaveric liver donor is particularly critical for children. Split liver transplantation, not only overcomes the drawbacks of reduced size grafts and living donor transplantation for children but also increases the total number of donor organs. The purpose of this study is to examine the technical feasibility of split liver transplantation in pig. METHODS: Nine pigs(3 donors and 6 recipients weighing 19-33Kg) were used. In donor pigs, the liver was divided between right medial lobe and left medial lobe without inflow occlusion under general anesthesia. Left liver was harvested first and then right liver was harvested as usual manner. One recipient pig underwent left lobectomy and left graft were transplanted orthotopically (auxiliary partial orthotopic liver transplantation(APOLT)). For right graft, conventional orthotopic liver transplantation were done. Veno-venous bypass was not performed. Instead, superior and inferior mesenteric arteries were clamped temporarily. RESULT: There was no anhepatic time when using left graft. Cold ischemic time were 2hr 35min, 1hr 21min, and 1hr 5min, respectively. When using right graft, anhepatic time was 72min, 54min, and 49min, respectively. Cold ischemic time was 5hr 17min, 6hr 32min, and 4hr 18min, respectively. Biochemical laboratory data(WBC, hemoglobin, platelet, ALT/AST, LDH, prothrombin time) after reperfusion 1 hour showed good graft function in all transplant pigs and were better in the recipient pigs taking left graft than right graft. Histologic findings at 4 hours after reperfusion show normal appearance except mild ischemic change around central vein. All transplant pigs survived over 24 hours without any major complication. CONCLUSION: APOLT for left graft and conventional liver transplantation for right graft without venovenous bypass were successful in pig. In situ split liver transplantation in pig is technically feasible procedure and this model is suitable for future studies of split liver transplantation.

BACKGROUND/AIMS: The aim of this study was to determine the clinical performances of noninvasive serum markers for the prediction of liver fibrosis in chronic viral liver diseases. METHODS: We analyzed a total of 225 patients with chronic viral liver diseases (180 with hepatitis B virus, 43 with hepatitis C virus, and 2 with hepatitis B+C virus) who underwent a liver biopsy procedure at the Hanyang University Guri Hospital between March 2002 and February 2007. Serum was also obtained at the time of liver biopsy. Liver fibrosis was staged according to the scoring system proposed by the Korean Study Group for the Pathology of Digestive Diseases. Various noninvasive serum markers were evaluated, including the aspartate aminotransferase (AST)/alanine aminotransferase (ALT) ratio (AAR), age-platelet (AP) index, AST/platelet ratio index (APRI), cirrhosis discriminant score (CDS), platelet count, hyaluronic acid (HA), and type IV collagen. RESULTS: There were 17, 40, 61, 74, and 33 patients at stages F0, F1, F2, F3, and F4, respectively. The overall diagnostic accuracies of each marker, as determined by the area under receiver operating characteristics curves, were APRI=0.822, CDS=0.776, platelet count=0.773, AP index=0.756, HA=0.749, type IV collagen=0.718, and AAR=0.642 for predicting significant fibrosis (> or =F2); and CDS=0.835, platelet count=0.795, AP index=0.794, HA=0.766, AAR=0.711, type IV collagen=0.697, and APRI=0.691 for predicting extensive fibrosis (> or =F3). CONCLUSIONS: All noninvasive serum markers evaluated in this study were useful for predicting significant or extensive liver fibrosis in chronic viral liver diseases. In particular, APRI was most useful for the prediction of significant fibrosis, and CDS was most useful for the prediction of extensive fibrosis.

BACKGROUND: Chronic placental inflammation, such as villitis of unknown etiology (VUE) and chronic chorioamnionitis (CCA), is considered a placental manifestation of maternal anti-fetal rejection. The aim of this study is to investigate its frequency in twin pregnancies compared to singleton pregnancies. METHODS: Three hundred twin placentas and 1,270 singleton placentas were consecutively collected at a tertiary medical center in Seoul, Republic of Korea from 2009 to 2012. Hematoxylin and eosin sections of tissue samples (full-thickness placental disc and chorioamniotic membranes) were reviewed. RESULTS: Non-basal VUE was more frequent in twin placentas than in singleton placentas (6.0% vs 3.2%, p < .05). In preterm birth, CCA was found less frequently in twin placentas than in singleton placentas (9.6% vs 14.8%, p < .05), reaching its peak at an earlier gestational age in twin placentas (29-32 weeks) than in singleton placentas (33-36 weeks). CCA was more frequent in twin pregnancies with babies of a different sex than with those with the same sex (13.8% vs 6.9%, p=.052). Separate dichorionic diamniotic twin placentas were affected by chronic deciduitis more frequently than singleton placentas (16.9% vs 9.7%, p<.05). CONCLUSIONS: The higher frequency of non-basal VUE in twin placentas and of CCA in twin placentas with different fetal sex supports the hypothesis that the underlying pathophysiological mechanism is maternal anti-fetal rejection related to increased fetal antigens in twin pregnancies. The peak of CCA at an earlier gestational age in twin placentas than in singleton placentas suggests that CCA is influenced by placental maturation.

Squamous cell carcinoma of the rectum is extremely rare. Herein we report two cases of rectal squamous cell carcinoma. Case 1 was a 44-year-old Korean female presenting with abdominal pain and rectal bleeding for 3 months before her hospital visit. A colonoscopic examination revealed an ulcerated rectal mass 8 cm proximal to the anal verge. Chemoradiotherapy was administered following Hartmann's procedure in case 1. The patient remained alive during 19 months of follow up. Case 2 was a 43-year-old Korean female who had severe constipation for 2 months. A barium enema and computed tomography of the pelvis showed a rectal mass adherent to the sacrum. Based on the results of a colonoscopic biopsy, a diverting colostomy was performed in case 2, with no further treatment. The pathologic findings showed that both tumors were composed of oval-shaped cells with abundant eosinophilic cytoplasm and intercellular bridges with keratin pearls, and thus were diagnosed as well-differentiated squamous cell carcinoma. Neither of the cases showed evidence of HPV infection. The pathogenesis of rectal squamous cell carcinoma has not been clarified. Herein we report two cases of rectal squamous cell carcinoma and briefly discuss the possible histogenesis.
