Pelvic radiography as a non-invasive screening tool for hiatal hernia in children with cerebral palsy
No full textThe diagnosis of hiatal hernia (HH), causing severe gastroesophageal reflux disease and complications in children with cerebral palsy (CP) is cumbersome because invasive investigations are required for diagnosis. Hip displacement, one of the most common complications in children with CP, can be diagnosed with a simple pelvic radiograph. This study aimed to evaluate the association between the severity of hip displacement and HH and the diagnostic accuracy of Reimers’ hip migration percentage (MP) on pelvic radiography in assessing the presence of HH. A total of 52 children with CP (27 boys, 25 girls; mean age, 6.3 years; range, 0.6–17.4 years) who underwent esophagogastroduodenoscopy, upper gastrointestinal series and pelvic radiography between March 2013 and February 2020 were recruited. Demographic and clinical characteristics, as well as endoscopic and radiological findings, were evaluated and statistically analyzed. HH was defined as ≥ 2 cm proximal displacement of the gastroesophageal junction identified in esophagogastroduodenoscopy or upper gastrointestinal series, and MP was calculated by evaluating the pelvic radiograph. Of the 52 children enrolled in this study, HH was diagnosed in 18 children (34.6%). When the patients were classified and analyzed according to the MP result, HH was observed in 10%, 26.7%, and 70.6% in MP 40% groups, respectively (P < .001). The optimal MP cutoff of 36.5% distinguished pediatric CP patients with HH from those without HH with a sensitivity of 78%, specificity of 68%, a positive predictive value of 56.0%, and a negative predictive value of 85.2%, respectively. The application of MP and the severity of hip displacement, which can be easily measured by simple radiography, may be useful and reliable in screening for detecting HH in children with CP. Retrospectively registered. This study was approved by the Institutional Review Board of Seoul National University Bundang Hospital (IRB No. B-2007-627-106)

Endoscopic and Histologic Analysis of Gastric Mucosa-Associated Lymphoid Tissue in Children With Helicobacter pylori Infection
No full textObjectives:Nodular gastritis (NG) associated with Helicobacter pylori infection can occur commonly in childhood and is regarded to be benign without clinical significance. This study includes endoscopic and histologic analysis of gastric mucosa-associated lymphoid tissue (MALT) to clarify the significance of NG on endoscopy in H pylori-infected children.Methods:Of the 758 children who underwent endoscopy, 80 were identified as having H pylori infection. These patients were divided into 3 groups based on endoscopic severity of gastric nodularity. Histopathologic grading of MALT and immunohistochemistry of CD3, CD20, cytokeratin, and Ki-67 were evaluated.Results:On endoscopy, severe NG was observed in the antrum of 38 of the 80 subjects, mild NG in 27, and an absence of NG in 15. Density of H pylori and lymphocyte infiltration differed among the 3 groups (P=0.022 and P=0.025, respectively). Histological grading for gastric lymphoid infiltrates was compatible with grade 1 in 47 (58.8%), grade 2 in 21 (26.3%), grade 3 in 7 (8.8%), and grade 4-5 in 4 (5.1%) in the antrum. Degree of NG, density of H pylori, neutrophil activity, and gastritis score in the antrum varied with MALT grades (P=0.003, P=0.042, P=0.028, and P=0.006, respectively).Conclusions:Our study suggests NG may present as a significant gastric manifestation of childhood H pylori infection that indicates gastric MALT. Thorough histologic investigation may be useful in the evaluation of gastric MALT in children infected with H pylori that manifests as severe NG in the antrum.N
The co-evolution of technology and institution in the Korean information and communications industry
No full textThe Korean IT industry has shown distinct patterns in learning mechanisms and organisational configuration throughout its entry into advanced information technology. Innovation systems in the area of information technology have also evolved along with technological capability, thereby changing the focus of technological strategies and the role of public institutions. It is found that distinctive patterns of learning and diffusion mechanisms in the case of DRAMs, TDX, and CDMA systems represent successful catch-up situations in Korea as presented in this paper. This paper characterises the stylised facts of the Korean innovation system in the IT sector and traces how technology and institutions coevolved throughout the development process. The transition from technology-using to technology-generating is not an automatic process. Cumulative learning in both technology and organisation is a critical factor to upgrade technological capabilities. The main policy implication of the paper is that it is important to design the cot-responding organisational and institutional arrangement in accordance with the changing need of technological upgrading.

No full textPembuatan Keputusan Presiden Park Geun Hye Dalam Penandatanganan General Security of Military Information Agreement (GSOMIA) Korea Selatan-Jepang Tahun 2016
No full textKontroversi penandatanganan GSOMIA yang sebelumnya dihadapi oleh Lee Myung Bak, kini dihadapi pula oleh presiden terpilih baru Korea Selatan, Park Geun Hye. Situasi beresiko terlihat dari masyarakat Korea Selatan yang tidak menyetujui adanya penandatanganan tersebut. Ditambah lagi, skandal politik dan korupsi yang melibatkan Park Geun Hye dengan kawan masa kecilnya memperkeruh suasana. Kondisi ini menunjukan bahwa Park Geun Hye berada pada kondisi yang buruk lantaran skandal dan juga data-data obyektif seperti minimnya dukungan partai, Majelis Nasional, dukungan masyarakat, dan pemberitaan di media yang negatif menanggapi penandatanganan GSOMIA. Berdasarkan prospect theory, domain buruk yang dimiliki Presiden Park Geun Hye membuatnya berani untuk mengambil pilihan paling beresiko, yaitu setuju menandatangani GSOMIA untuk mengalihkan kasus politik yang sedang menerpanya
DARI LIYAN MENUJU SUBJEK (Representasi Tubuh Young-Hye dalam Novel The Vegetarian Melalui Perspektif Feminisme Eksistensialis Simone De Beauvoir)
No full textSkripsi ini dengan judul “Dari Liyan Menuju Subjek: Representasi Tubuh Young-hye dalam Novel The Vegetarian Melalui Perspektif Feminisme Eksistensialis Simone de Beauvoir” ditulis oleh Wakhidatul Rofiqoh, NIM. 126302212043, dengan pembimbing Dr. Lailatuzz Zuhriah, M.Fil.I.
Kata Kunci: Feminisme Eksistensialis, Liyan, Simone de Beauvoir, The Vegetarian
Penelitian ini dilatarbelakangi oleh fenomena keterbatasan pengalaman tubuh perempuan. Dengan membawa keresahan tersebut, penulis menemukan problem serupa dalam karya sastra. Ialah tokoh Young-hye yang tak memiliki kendali penuh atas hidup dan tubuhnya. Maka penelitian ini bertujuan untuk: (1) Mendeskripsikan posisi Young-hye sebagai perempuan dalam masyarakat patriarkal sebagaimana direpresentasikan dalam novel The Vegetarian (2) Menganalisis bagaimana konsep “The Other” Simone de Beauvoir tercermin dalam karakterisasi dan narasi tokoh Young-hye dalam novel The Vegetarian (3) Menganalisis proses transedensi Young-hye dari posisi sebagai “Liyan” menuju subjek melalui konsep feminisme eksistensialis Simone de Beauvoir. Pendekatan yang digunakan adalah pedekatan kualitatif deskriptif yang berusaha menjelaskan realitas dengan menggunakan penjelasan deskriptif menggunakan kalimat yang rinci, mendalam dan mudah dipahami. Sumber data primer yang digunakan peneliti berupa novel The Vegetarian karya Han Kang, buku The Second Sex versi bahasa Indonesia dan Bahasa Inggris. Serta berbagai literatur seperti jurnal, skripsi, atau dokumen lain dari internet yang membahas tema terkait dikaji sebagai data sekunder. Dengan menggunakan kerangka feminisme eksistensialis Simone de Beauvoir, hasil penelitian yang diperoleh menunjukkan bahwa: (1) Tokoh menolak peran-peran tradisional perempuan yang dibentuk budaya patriarki dengan melalui gaya hidup vegetarian. Hal ini dilakukanya untuk membebaskan dirinya dari konstruksi “perempuan ideal” yang mengakar dalam masyarakat (2) Posisi Liyan yang melekat pada Young-hye merupakan sebuah hasil perilaku yang dikontruksi masyarakat demi kepentingan pribadi yang merugikan hidup perempuan (3) Obsesi Young-hye menjadi vegetarian merupakan ekspresi kebebasanya untuk mencapai eksistensinya, dan terlepas dari identitas yang dilekatkan padanya
Design of Nonbinary LDPC Codes Based on Message-Passing Algorithms
No full textShort cycles in a nonbinary low-density parity-check (NB-LDPC) code may he even more harmful to its performance if they do not satisfy the so-called full rank condition (FRC). This is because they may induce low-weight codewords or absorbing sets in that case. Thus, it is important to count the number of short cycles not satisfying the FRC as well as the number of short cycles for analyzing the performance of an NB-LDPC code. In this paper, we first develop a novel message-passing algorithm and identify how it is related to the FRC. We then propose a low-complexity algorithm for counting the number of short cycles not satisfying the FRC in an NB-LDPC code, as well as the number of short cycles. Finally, we propose a low-complexity algorithm for designing an NB-LDPC code with low error floor. Depending on the modulation scheme, the codes constructed by the proposed design algorithm have similar or slightly worse performance, compared with those constructed via the method by Poulliat et al. However, the proposed design algorithm does not require a cycle enumeration algorithm with high complexity, and therefore is feasible even in the case of large code length, say >= 5000.110sciescopu
