This study is aimed to produce natural dyeing garments, which contain the sentiments and color sense of Koreans, by using various household supplies, with a view to increase the values added and utilization of natural dyeing. The dyes mainly used for this study are multi-colored ones which are durable after dyeing and can represent various colors. They include Lithodpermum officinale, Caesalpinia sappan, Rubia Cordifolia, Pellodendron Bak, Curcuma Longa L., fallen Ginkgo Biloba, Artemisia Princeps, and Quereus acutissima carr shell. Considering water pollution and other things, aluminum acetate and ferrous chloride were used as mordants. Cheap and practical materials such as cotton cloth and those with traditional patterns and elegance such as silk and ramie fabrics were used to produce baby goods, household supplies, clothes, and accessories. The produced supplies closely contact with our body, so they may have a great effect on human body. The household supplies produced include rug, bedclothes, room bedclothes, curtain, bedding set, cushion, and sunlight blind, in consideration of the functionality or medical actions of the goods which are closely related to the human skin. The infant supplies produced include longcloth for newborn baby, bedding set, gauze handkerchief, and doll. The clothes include night gown, shirt, bath gown, and Korean traditional clothes. The accessories include tablecloth, cup pad, bag, wrapping cloth, mouse and keyboard cushion, and scarf. Nowadays, consumers prefer environment-friendly naturally dyed garments and products. In order to control the naturally dyed garments and products which are traded in the domestic market, it is urgent to introduce such ecological marks as 'Toxproof' and 'Ecoproof.' Currently, many ordinary persons, who are not experts, have interest and participate in natural dyeing, but they simply produce naturally dyed garments, not artistic works or everyday supplies. The present author expects this study will contribute to the production of household goods by such persons. The author also hopes that they will develop and commercialize such designs as suit to modern tastes and senses based on the unique cultural assets of Koreans, so that Korean naturally dyed products may be recognized as reliable commodities equipped with international competitiveness.

Purpose: Infantile Marfan syndrome (MFS) is a rare congenital inheritable connective tissue disorder with poor prognosis. This study aimed to evaluate the cardiovascular manifestations and overall prognosis of infantile MFS diagnosed in a tertiary referral center in Korea. Methods: Eight patients diagnosed with infantile MFS between 2004 and 2014 were retrospectively evaluated. Results: Their median age at the time of diagnosis was 2.5 months (range, 0-20 months). The median follow-up period was 25.5 months (range, 0-94 months). The median length at birth was 50.0 cm (range, 48-53 cm); however, height became more prominent over time, and the patients were taller than the 97th percentile at the time of the study. None of the patients had any relevant family history. Four of the 5 patients who underwent DNA sequencing had a fibrillin 1 gene mutation. All the patients with echocardiographic data of the aortic root had a z score of >2. All had mitral and tricuspid valve prolapse, and various degrees of mitral and tricuspid regurgitation. Five patients underwent open-heart surgery, including mitral valve replacement, of whom two required multiple operations. The median age at mitral valve replacement was 28.5 months (range, 5-69 months). Seven patients showed congestive heart failure before surgery or during follow-up, and required multiple anti-heart failure medications. Four patients died of heart failure at a median age of 12 months. Conclusion: The prognosis of infantile MFS is poor; thus, early diagnosis and timely cautious treatment are essential to prevent further morbidity and mortality.

Hypoplastic left heart syndrome is currently the most lethal cardiac malformation of the newborn infant. Survival following a Norwood operation depends on the balance between systemic and pulmonary blood flow, which is highly dependent on the fluid dynamics through the interposition shunt between the two circulations. The purpose of this study is an optimization of the systemic-to-pulmonary artery shunt. In this study, We used computational fluid dynamic(CFD) models to determine the velocity profile in a systemic-to-pulmonary artery shunt and suggested a simplified method of calculating the blood flow in the shunt based on Ultrasound systems. We analyzed the flow characteristic variations and oscillatory shear index(OSI) due to the anastomosis angle and shunt diameter changing. Four different CFD models were constructed with the shunt sizes ranging from 3 to 3.5mm. The angle between the brachiocephalic trunk(BCT) and the shunt were $30^{\circ}$ and $45^{\circ}$, respectively. When the diameter is 3.0 mm, the oscillatory shear index decreased by 1.2% at $30^{\circ}$ as opposed to at $45^{\circ}$. When the diameter is 3.5 mm, it increased by 18% more at $30^{\circ}$ as opposed to at $45^{\circ}$. When the joint angle is $30^{\circ}$ and the diameter is 3.0 mm, the oscillatory shear index decreased by 4.1% in comparison with the 3.5 mm diameter. When the angle is $45^{\circ}$ and the diameter is 3.0 mm, the index increased by 14.6% in comparison with the 3.5 mm diameter.

Purpose: Ethiopia is one of the sub-Saharan countries most affected by high maternal and infant mortality. The government has trained health extension workers (HEWs), the community health workers, to deliver preventive and basic curative health services to community residents in Ethiopia. Very few studies have investigated on-the-job educational effects for HEWs on improvement of their knowledge and performance confidence in maternal and child health care (MCH). This study aimed at identifying the educational effects for HEWs in one health center in Tigray, Ethiopia on improvement of their knowledge in MCH. Methods: Twelve HEWs from 6 health posts participated in this study. A health center officer provided a total of 5 educational sessions on antenatal and postnatal care, family planning, and newborn care from August, 2012 to April, 2013. Ten to 12 items regarding the topics were tested before and after each education. Wilcoxon signed rank test was used to analyze the data. Results: All the HEWs were female with average 4-year working experience. Their knowledge significantly increased after education, except the first session. Their satisfaction on education was greater than 45 points out of 50. Conclusion: This study suggests a focused education for HEWs should continue to improve their capacity on MCH.

Purpose: To develop and evaluate a simple screening tool to assess hearing loss in newborns. A derived score was compared with the standard clinical practice tool. Methods: This cohort study was designed to screen the hearing of newborns using transiently evoked otoacoustic emission and auditory brain stem response, and to determine the risk factors associated with hearing loss of newborns in 3 tertiary hospitals in Northern Thailand. Data were prospectively collected from November 1, 2010 to May 31, 2012. To develop the risk score, clinical-risk indicators were measured by Poisson risk regression. The regression coefficients were transformed into item scores dividing each regression-coefficient with the smallest coefficient in the model, rounding the number to its nearest integer, and adding up to a total score. Results: Five clinical risk factors (Craniofacial anomaly, Ototoxicity, Birth weight, family history [Relative] of congenital sensorineural hearing loss, and Apgar score) were included in our COBRA score. The screening tool detected, by area under the receiver operating characteristic curve, more than 80% of existing hearing loss. The positive-likelihood ratio of hearing loss in patients with scores of 4, 6, and 8 were 25.21 (95% confidence interval [CI], 14.69-43.26), 58.52 (95% CI, 36.26-94.44), and 51.56 (95% CI, 33.74-78.82), respectively. This result was similar to the standard tool (The Joint Committee on Infant Hearing) of 26.72 (95% CI, 20.59-34.66). Conclusion: A simple screening tool of five predictors provides good prediction indices for newborn hearing loss, which may motivate parents to bring children for further appropriate testing and investigations.

Background: Pain during the developmental period may adversely affect developing neuronal pathways and result in adverse neurodevelopmental, cognitive, and behavioral effects in later life. Immunizations, e.g., hepatitis B vaccine (HBV), administered at birth are painful experiences to which neonates are universally subjected. Purpose: Here we aimed to study and compare the effectiveness of various nonpharmacological pain management methods in newborns to enable the development of safe and effective analgesic methods for newborns. Methods: This prospective study was conducted at a tertiary care hospital in the Himalayan region. Three hundred term healthy neonates were divided into 6 groups of 50 each. Groups 1-5 were intervention groups, patients of which received a nonpharmacological intervention (breastfeeding, nonnutritive sucking, rocking, 25% sucrose, or distilled water) before the intramuscular HBV, while patients in group 6 received no intervention. The pain response in each group after the HBV injection was assessed and compared using cry duration and Douleur Aigue Nveau-ne (DAN) score, a behavioral acute pain rating scale for newborns. Results: Cry duration was decreased in all intervention groups, significantly so in the sucrose (19.90 seconds), breastfeeding (31.57 seconds), and nonnutritive sucking (36.93 seconds) groups compared with controls (52.86 seconds). DAN scores decreased significantly (P<0.05) at one or more points i.e. 30, 60, or 120 seconds in the breastfeeding and 25% sucrose intervention groups compared with controls. Conclusion: Oral sucrose and nonnutritive sucking are simple yet underutilized nonpharmacological interventions that effectively reduce pain in newborns.

The congenital epulis of newborn is a rare benign tumor that occurs on the gingiva of the anterior alveolar ridge of the jaws, also known as a congenital granular cell tumor. Females are affected 8 - 10 times more often than males. The typical location is the alveolar ridge of the maxilla near the canine but the mandibular region can also be involved. The lesion may be sessile or pedunculated with red or normal color. The size of tumor varies from several millimeters to a few centimeters in diameter. Surgical excision is generally indicated and no recurrences have been noticed. Spontaneous regression is rare. It is histologically similar to the granular cell tumor, although pseudoepitheliomatous hyperplasia does not occur in the former lesion. Thus sheets of large, closely packed cells showing fine, granular, eosinophilic cytoplasm comprise the tumor mass. This is a case report of congenital epulis in the fetus. The lesion was detected in ultrasonogram, its size is 3cm in diameter. The infant showed nursing disturbance and respiratory obstruction after birth, so the tumor was surgically excised under local anesthesia.
