The pancreas consists of two types of tissue arising from same primitive cells, but with entirely different functions. Although the adult human pancreas and fetal islet tissue have been the subject of numerous electron microscopic studies, little is known of the ultrastructure of the developing human exocrine pancreas. The purpose of the current study is to investigate development of endo and exocrine of pancreas, especially during the middle trimester of human fetal life, which is the period of acinar cell maturation. Fresh autopsy specimens of pancreas, taken from 15 human fetuses at the 12th (n=2), 13-16th (n=5), 17-20th (n=4), 21-24th (n=2) and 25-28th (n=2) weeks of gestation, were studied electron microscopically, and immunohistochemically. Antisera against insulin, somatostatin, glucagon, pancreatic polypeptide and gastrin, were used for immunohistochemistry. By the 12th week, primitive exocrine acini were identified and these were matured rapidly in the next 6 weeks. At the 17th week stage, ultrastructural examination revealed atypical zymogen granules in the acinar cells. These became progressively less numerous in the 21-28 week period when classical zymogen granules increased upto the level of adult stage. All the endocrine cells were found at the 12th week, forming primitive or mature islets. The relative ratio of endocrine cells at the 12th week was about 35.4%, 24.9%, 39.8%, 0.5% for A, B, D & PP cell, respectively. But at the 25th to 28th week of development, the relative numbers of A and D cells decreased somewhat, whereas those of the B cells increased. The PP cells were constant. The G cells were found at the 12th week of fetal period, which appeared through out the on period.

BACKGROUND: This study was to identify factors affecting the job satisfaction of pediatric nurse.METHODS: The participants were the 190 nurses who worked in five pediatric ward and hospital in G city. Data were collected using structured questionnaires from August 1 to August 31 2014, and analyzed using descriptive statistics, t-test, ANOVA, Tukey, Pearson correlation analysis, and multiple linear analysis with the SPSS PC+ 21.0 program.RESULTS: The variables that affect job satisfaction of pediatric nurses were nurse-parent partnership(β=.30, p<.001), Nursing duty(β=−.24, p=.006), Lack of professional knowledge and skills(β=−.24, p=.002), treatment of nurses(β=−.22, p=.014). These factors accounted for 31.0% of the variance in the job satisfaction.CONCLUSION: This study shows that the methods for increasing nurse-parent partnership and reducing job stress are needed, so as to enhance job satisfaction of nurses who are working pediatric ward.

Two cases of urachal anomaly (1 urachal cyst and 1 patent urachus) are reported in a neonate and an eleven-year old boy, respectively. In case 1, the patient was born after an uncomplicated pregnancy to a mother who had taken progesterone during the first trimester. Because of breech presentation, cesarian section was elected to deliver a male baby weighing 2.3 kg who showed abdominal distension. The patient died of respiratory difficulty several minutes after birth. At autopsy, there was a large cyst in the midpoint of the abdominal and pelvic cavity. This round cyst was composed of two components, urachus and urinary bladder. No area of umbilicocystic fistula was present. The lining epithelium was chiefly of transitional type. Assocaited anomalies were segmental stenosis of posterior urethra, absence of abdominal musculature, bilateral polycystic kidney of Potter type IV, hydroureter, and hypoplasia of lungs. Low set ears, micrognathia and club foot were also present. In case 2 the patient was 11-year old boy. He had suffered from intermittent urinary dribbling from umbilicus since early infancy, whenever the abdominal pressure was increased. The patency of urachus was confirmed by fistulography. And the urachal anomaly was surgically removed. Histopathologically the resected patent urachus consisted of pseudostratified columnar to transitional epithelium resting on fibrous stroma mixed with well formed smooth muscle bundles.

BACKGROUND: The purpose of this study is to evaluate the evidence for the effectiveness of different isolation policies in reducing the incidence of methicillin-resistant Staphylococcus aureus (MRSA) infection in hospital in-patients. METHODS: We prospectively evaluated the effectiveness of an isolation policy on transmission of MRSA in the 745-beds hospital. First period, all patients with MRSA (March - July 2000) were not isolated Second period, strict isolation policies were performed (August 2000 - January 2002). All patients with MRSA were isolated in separated room, hand hygiene using alcohol handrub, gowning and g1oving, apply of MRSA notice sticker, criteria in isolation remove, separated disinfection and wastement. Third period, semi strict isolation policies were performed (February 2002 - August 2005). Some patients with MRSA were isolated in separated room and others were admitted in general ward for bed shortage. Only some practices were performed in hand washing and separated disinfection in general ward. RESULTS: The rates of MRSA nosocomial infection per patients during 1st, 2nd, and 3rd surveillance were reported 0.56, 0.23, and 0.42 (P<0.05). Patient-days rate of MRSA nosocomial infection during 1st, 2nd, and 3rd surveillance were reported 0.62, 0.27, and 0.38 (P<0.05). CONCLUSION: With many different isolation policies, it was possible to reduce nosocomial infection of MRSA. In this study, strict isolation policies (2nd period) were the most effective practices in reducing MRSA infection.

BACKGROUND/OBJECTIVES: International students face dissimilar food environments, which could lead to changes in dietary behaviors and anthropometric characteristics between before and after migration. We sought to examine the risk factors, including dietary behaviors, acculturation, and demographic characteristics, related to overweight subjects residing in South Korea. SUBJECTS/METHODS: We conducted a cross-sectional study, collecting data from 142 Chinese international students (63 males, 79 females) in 2013. RESULTS: The mean age of the subjects was 25.4 years, and almost half of them immigrated to South Korea to earn a master's degree or doctoral degree (n = 70, 49.3%). Chinese international students showed an increase in skipping meals and eating speed, but a decrease in the frequency of fruit and vegetable consumption in South Korea compared to when they lived in China. We found a statistically significant increase in weight (69.4 --> 73.9 kg) and BMI (22.4 --> 23.8 kg/m2) for male subjects (P < 0.001) but no change for female subjects. We also found that overweight subjects were more likely to be highly acculturated and male compared with normal-weight subjects. CONCLUSION: Among Chinese international students living in South Korea, male and more highly acculturated subjects are more vulnerable to weight gain. This study provides useful information to design tailored nutrition intervention programs for Chinese international students.

The purpose of this study was to investigate changes in dietary life, lifestyle factors, and stress status of Chinese students who came to study abroad to South Korea. A total of 143 Chinese students were recruited from Seoul Women's University and Wonkwang University in 2013. We used SPSS 20 for statistical analyses in this study. The mean length of residence was 2.9 years for Chinese students. Most subjects aged 20–29 years immigrated to South Korea to obtain an academic degree (bachelor, master, or doctorate). We found a significant decrease in the frequency of eating fruits and vegetables among Chinese students in South Korea after migration. Further, there was a significant increase in fast food consumption and frequency of late-night snacking and eating out. In addition, their preferred beverage changed from soft drink or tea to coffee after migration. Stress level significantly (P < 0.05) increased in male students compared to female students. The high stress group watched more TV when eating compared to the low stress group. In addition, there were more students who perceived their health status as bad in the high stress group. Overall results give us useful information for targeting the most vulnerable subjects and planning nutrition intervention programs.
