Purpose: Many diagnostic modalities have been used for diagnosis of gastroesophageal reflux disease (GERD). Feeding materials during esophageal pH monitoring may interfere the result of examination and esophageal pH monitoring can not diagnose GER in case of alkaline reflux. The purpose of our study is to evaluate whether scintigraphy can substitiute 24 hr pH monitoring in children with GERD. Methods: From March 2002 to June 2003, 23 patients (12 boys and 11 girls, mean age 27 months) who have been admitted to Hanyang University Hospital presented with GER symptoms (recurrent vomiting, cough, chest pain, irritability) were included in the study. Scintigraphy and 24 hr pH monitoring were performed in all patients. Results: Six out of the 23 patients (26.1%) had evidence of GER on 24 hr pH monitoring, whereas nine of 23 patients (39.2%) exhibited GER by scintigraphy. Two out of the 23 patients could not be tested because of irritability. Three (14.3%) patients had evidence of GER on both 24 hr pH monitoring and scintigraphy, three (14.3%) patients on only 24 hr pH monitoring, six (28.6%) patients on only scintigraphy, and nine (42.9%) patients had no evidence of GER on both methods. No correlation was observed between 24 hr pH monitoring and scintigraphic results by Fisher's exact test (p=0.523) or Kendal's tau (t=0.678). Conclusion: The results of this study demonstrated that there was no correlation between 24 hr pH monitoring and scintigraphy. Therefore these modalities could be used as complementary tests to diagnose GERD.

Purpose : The purpose of this study is to investigate the material in middle school and high school textbooks covering child care and children's health for medically inaccurate content and to make sure that the correct information is given to students. Methods : We have examined 47 kinds of textbooks on the subjects 'Home economics' and 'Technology and home economics' published in 2007 to find out how much importance is placed on children's health and childcare and to search for incorrect definitions, inaccurate facts or insufficient explanations. We have also analyzed the credentials of the writers of these textbooks. Results : Textbooks of middle school cover psychological and physical changes during adolescence and nutrition, and those of high school cover marriage and childcare. These materials covering health made up 27.5%, 11.7% of middle & high school texts. Age definitions of neonate and infant were incorrect. Inaccurate facts were mostly about fontanelles, primitive reflexes, breastfeeding and weaning. There also were wrong informations on the umbilical cord care and developmental milestones during infancy. The childhood immunization schedules and the growth curves were not up to date. Most of the authors major in home economics and the others were school teachers. There was no evidence of any review by a medical society or an expert. Conclusions : When writing about children's health and childcare in textbooks, a board-certified pediatrician or The Korean Pediatric Society should be consulted to provide accurate medical information to middle and high school students.

Purpose Some patients with neonatal seizures show diffuse, symmetric diffusion-restricted lesions in the cerebral white matter. The aim of this study was to describe clinical and imaging findings of patients with neonatal seizures who had diffuse, symmetric diffusion-restricted lesions without any structural or metabolic etiology. Materials and Methods A total of 56 neonates aged less than 1 week underwent brain magnetic resonance imaging (MRI) for evaluation of seizures from November 2008 to February 2017. After excluding 43 patients, 13 patients showed diffuse white matter abnormality on diffusion-weighted imaging. Initial and follow-up clinical and MRI findings were analyzed retrospectively. Results All 13 patients were born at full term. Among the ten patients who underwent a stool test for viruses, six were positive for rotavirus and one for astrovirus. MRI revealed diffuse, symmetric diffusion-restricted lesions distributed along the cerebral white matter, thalami, and midbrain variably. Conclusion Diffuse, symmetric diffusion-restricted lesions involving the cerebral white matter can be seen in patients with neonatal seizures without any structural or metabolic etiology. Rotavirus is commonly but not exclusively detected in these patients. Nevertheless, viral infection-associated encephalopathy should be considered for patients with characteristic clinical and MRI findings.

In the natural world, most materials such as skin, marble and cloth are translucent. Their appearance is smooth and soft compared with metals or mirrors. In this paper, we propose a new GPU based hierarchical rendering technique for translucent materials, based on the dipole diffusion approximation, at interactive rates. Information of incident light, position, normal, and irradiance, on the surfaces are stored into 2D textures by rendering from a primary light view. Huge numbers of pixel photons are clustered into quad-tree image pyramids. Each pixel, we select clusters (sets of photons), and then we approximate multiple subsurface scattering term with the clusters. We also introduce a novel hierarchical screen-space interpolation technique by exploiting spatial coherence with early-z culling on the GPU. We also build image pyramids of the screen using mipmap and pixel shader. Each pixel of the pyramids is stores position, normal and spatial similarity of children pixels. If a pixel's the similarity is high, we render the pixel and interpolate the pixel to multiple pixels. Result images show that our method can interactively render deformable translucent objects by approximating hundreds of thousand photons with only hundreds clusters without any preprocessing. We use an image-space approach for entire process on the GPU, thus our method is less dependent to scene complexity.

This study focused on the nutrition knowledge, food purchase behaviors, and dietary habits of 213 housewives (41 women under 39 years, 98 women 40~49 years, and 74 women over 50 years). Younger housewives held more special jobs, whereas older housewives worked as housewives or had no jobs ($p$<0.05). The average monthly income of the three family groups was 3,000,000~5,000,000 won, and the monthly dietary expenditure for all three groups was 200,000~500,000 won. Familial frames for the three groups was nuclear family (over 80%), but housewives younger than 39 years (19.5%) lived together with their parents and let them take care of their children. Housewives (over 50 years) prepared a balanced diet for every meal, utilized less drastic cooking methods to prevent loss of nutrients, and shopped at many places in order to save money on various food materials. Further, they purchased food materials that resulted in the least amount of left overs. On the other hand, housewives under 39 years visited large supermarkets and purchased cooked foods more than other groups. Housewives under 39 years considered nutrients content as the most important factor when purchasing food materials, whereas 74.5% of housewives between 40~49 years and 51.4% of housewives over 50 years put the most importance on flavor ($p$<0.05). Housewives under 39 years were interested in manufacture date, nutrient content, and food price, in decreasing order, whereas housewives between 40~49 years and over 50 years were interested in manufacture date, food prices, and nutrient content. Older housewives were interested in brown rice and fruits, whereas younger housewives under 39 years were interested in meat, fish, eggs, fried foods, and fast food. Older housewives over 50 years did not consume fried foods more than two times per week and consumed three regular meals more often than younger housewives. Accordingly, for younger housewives, it is necessary that healthy foods be cooked for their families.

The purpose of this study is to propose criteria for selecting picture books as various reading education materials for middle school students and to check whether it can be applied to book selection. First, identified the educational value of picture books as reading materials and the criteria for selecting picture books by academic field through previous studies. After integrating the commonalities of various picture book selection criteria presented in previous studies by categorizing them into illustrations, text, and other categories. And it devised selection criteria that can be applied after selecting middle school students as readers. Based on the unified picture book selection criteria, a survey was conducted to ask in-service librarians about the main criteria to consider when selecting picture books for middle school students, and intensive interviews were conducted with experts who have experience in picture book education. As a result, the picture book selection criteria from previous studies were revised and supplemented with two criteria related to text, four criteria related to pictures, and five other criteria, and presented as picture book selection criteria for middle school students. To verify the practicality of the picture book selection criteria, it checked the applicability of each category of criteria to picture books recommended by the Children's Book Research Society (ages 13 and older). Out of 22 picture books for middle school students, 15 books could be applied to all categories of the selection criteria, showing significant practicality.

The purpose of this study is to show that the reason behind the ambivalent characteristic displayed in Niki de Saint Phalle's works is in her trauma and how such characteristic can be extracted from her works. During her creative years, Saint Phalle worked on various materials from different genres such as assemblages, shooting paintings, a series on Bride and Monster, 'Nana', 'Tarot Garden'and public sculptures. One commonality found among her various works is the ambivalent characteristic that contains contrasting elements simultaneously. Saint Phalle suffered a terrible psychological damage inflicted by her parents during her childhood. Specifically, she was sexually assaulted by her father and emotionally neglected by her mother, the trauma that affected her for the rest of her life. As a result, she came to develop extreme love- hate relationships with her parents and this became the main reason for the ambivalent characteristic displayed in her works. The love-hate relationship Saint Phalle developed can be identified through various researches done on the subject of the affect of sexual assault. It is common for incest victims to develop ambivalent feelings towards the perpetrator and Saint Phalle was no exception. Dissociation disorder and a snake well explain the trauma from her father. It is a generally accepted belief in the field of psychology that dissociation disorder commonly occurs to children who experience incest. And dissociation disorder is similar to the characteristic of ambivalence in the sense that a single entity contains more than two contrasting elements at the same time. In addition, the amputated doll objects used in her assemblages coincide with the expression of body detachment of people with dissociation disorder. These facts clearly indicate that the trauma from her father is showing through in her works. A snake is a subject matter that reflects the ambivalent tendency of Saint Phalle that resulted from her trauma. She remembers her father's rape as an image of a snake which is related to a phallic symbol in mythology or art reflecting her trauma. Moreover, she displays a similar pattern of ambivalent emotion like love and hate or fear towards a snake and her father. This is also confirmed by her portrayal of a snake as a monster or reversely as a creature with fundamental vitality in her works. The lack of affection from her mother can be explained by her mother's maternal deprivation. It appears that Saint Phalle's mother possessed all the causes for maternal deprivation such as maternal separation, personality disorder and inappropriate attitude towards child rearing. Especially, a study that shows mother's negative attitude towards child breeding tends to increase dissociation experience of children is another important evidence that supports Saint Phalle's dissociation tendency. These traces of Saint Phalle's trauma are clearly revealed in her assemblages and shooting paintings. The violent objects in her assemblages such as a hammer, razor, nail represent the rage and defensiveness towards her father. The objects such as fragments of broken plates of feminine patterns, pots and mirrors that her mother used symbolize the affection towards her mother. On the other hand, the destructed objects can be interpreted as her hate and resentment towards her mother. Shooting paintings contain her extreme fury and hate. Things such as acts of shooting and the image associated with blood after shooting are blunt expressions of her bursts of emotions. I have tried to define and classify the ambivalent characteristics shown in her assemblages and shooting paintings as hate, rage, violence, calm, love and pleasure according to the frame of Thanatos and Eros. Out of the six, hate, rage, violence and clam are associated with Thanatos while love and pleasure are associated with Eros and they correspondingly form an ambivalent structure. These ambivalent characteristics can be found in her assemblages and shooting paintings. The objects in her assemblages such as a razor, saw, hammer imply hate, rage, violence and the silence felt throughout her works represent calmness. And, as mentioned, the feminine objects can be seen as symbolizing love. In shooting paintings, hate, rage, violence can be found in the use of force and in the traces of watercolor after shooting, and a sense of pleasure in her feelings of catharsis after her shooting. Moreover, a shielded calmness can be found on the plywood all covered with plaster before the shooting. This study looked into the ambivalent characteristic of Saint Phalle's works by examining her trauma to find its correlation, and a meaning of this study can be found from the fact that it refocused the origin of Saint Phalle who is generally known as a feminist artist. Additionally, a meaning of the study can be found also from the fact that it examined the ambivalent characteristics of her works through a frame of Thanatos and Eros.

Background: Serum Golgi protein 73 (GP73) as a novel and potential marker for diagnosing hepatocellular carcinoma (HCC) have been found to be elevated in HCC patients and associated with clinical variables representing tumor growth and invasiveness. The aim of this study was to prepare a pair of monoclonal antibodys (mAbs) against GP73 and develop a newly designed double-antibody sandwich enzyme-linked immunosorbent assay (s-ELISA), which would be used in the detection of serum GP73 (sGP73) as well as in the diagnosis of HCC. Materials and Methods: Produced by prokaryotic expression, the purified recombinant GP73 (rGP73), produced by prokaryotic expression, was used to immunize the Balb/c mice. Two hybridoma cell lines against GP73 were obtained by fusing mouse Sp2/0 myeloma cells with spleen cells from the immunized mice. The titers of anti-GP73 mAb reached 1:243,000. Western blotting analysis and Immunohistochemistry staining revealed that anti-GP73 mAb could recognize GP73 protein. The double-antibody s-ELISA was successfully established and validated by 119 HCC and 103 normal serum samples. Results: showed that the detection limit of this method could reach 1.56 ng/ml, and sGP73 levels in HCC group (mean=190.6 ng/ml) were much higher than those of in healthy controls (mean=70.92 ng/ml). Conclusions: Results of our study not only showed that sGP73 levels of HCC patients were significantly higher than those of healthy controls, but also indicated that the laboratory homemade anti-GP73 mAbs could be the optimal tool used in evaluating sGP73 levels, which would provide a solid foundation for subsequent clinical applications.

The purpose of this study was to compare the success rates of two pulp capping materials, Biodentine™ and RetroMTA^®, used for partial pulpotomy in permanent molars after carious exposures and to compare the final restorative outcome of using composite resin to that of using a stainless steel crown. We studied children who were diagnosed with dental caries of permanent molars and underwent partial pulpotomy. The patients were followed up for more than 1 year. Clinical and radiographic evaluation were used to evaluate the success of each treatment. Fisher's exact test was used to compare the outcomes of two groups. For pulp capping agents, the success rate of using RetroMTA^® was lower than that of using Biodentine™(p < 0.05). Final restoration with composite resin was less successful than restoration with an stainless steel crown(p < 0.05). In combination of pulp capping agents and final restoration material, RetroMTA^®-composite resin shows the lowest success rate(p < 0.05).

The purpose of this study is to suggest implications from the case of health information service for patients in overseas hospital libraries. A total of 89 overseas hospital libraries were selected, including general hospitals, specialized hospitals, women's hospitals, children's hospitals, and veterans' hospitals. The health information service that is provided in general and common in 89 hospital libraries was surveyed and the differentiated health information service was investigated next. As a result, first, it can be seen that the establishment of hospital libraries and the provision of health information services are common outside of Korea. Second, various human resources such as librarians, health information specialists, medical specialists, social workers, clinical librarians, health education specialists, and volunteers are utilized. Third, it provides not only print materials but also various information sources such as electronic materials, websites, pamphlets, brochures, and provides health information in various languages. Fourth, in providing health (information literacy) education and programs, services are provided through linkage with hospitals, local public libraries, and local communities. The implications for domestic hospital libraries are as follows: First, the change of awareness of the establishment of hospital libraries and the provision of health information services; second, the support of the curriculum and associations and the need for continuing education; third, it is necessary to link with related organizations for mandatory and diversification of health information services in hospital libraries.
