Objectives : The purpose of this study was to examine relationships between bone age and body composition to make efficient clinical reviews on children's growth. Methods : 157 of children in age of 3 years to 16 years old were participated in this study(88 of boys and 69 of girls). They visited the department of pediatrics, OO university oriental hospital and were measured their body composition and bone age. Results : 1. An age and bone age, height, weight, and body mass index were positively correlated, and also a bone age and height, weight, and body mass index were positively correlated. 2. The level of soft lean mass, body fat mass, and MPH were increased in boys in higher height percentile. Children's predicted adult height was higher in children in higher height percentile. 3. The level of body fat mass was increased as weight percentile increased. Bone age, MPH was increased as weight percentile increased, especially in case of boys. In girl's case, the level of soft lean mass, their predicted adult height, the difference between children's bone age and their actual age was increased as weight percentile increased. Conclusions : Measuring bone age and body composition is the effective way to estimate children's growth and development in future.

부분 무치악 환자에서 구강 기능의 회복을 위한 보철 계획을 수립할 때, 잔존하는 치아에 따라 다양한 치료 방법을 선택할 수 있다. 특히 대합이 상실된 소수의 잔존치가 불안정한 교합을 야기하는 엇갈린 교합의 경우, 대합 되는 위치에 임플란트를 식립함으로써 교합지지를 회복할 수 있다. 이 증례에서는 발치 후 엇갈린 교합이 된 환자에서 의치의 하중을 견딜 수 있도록 상악 잔존치에 대응하는 하악 무치악 부위에 임플란트를 식립하고 자석유지장치(magnetic attachment)를 연결하는 국소의치를 제작하였다. 또한 상악 전치의 돌출과 하악 입술 지지도가 부족한 것을 개선하고 싶어한 환자의 요구사항에 따라 상악 전치부 보철적 수복 및 하악 의치를 통해 심미적 안모를 회복하였다. 5개월 정기검진 결과, 환자는 저작 기능 및 심미적인 면에서 만족하였고 의치의 안정성 또한 잘 유지되고 있기에 이를 보고하고자 한다. When attempting to restore the oral function of a partially edentulous patient, there are a number of prosthetic treatment options available, depending on the structure of remaining teeth. For example, when only one set of maxillary and mandibular teeth are diagonally in place across from each other, it is difficult to gain stable occlusion. In this case, implants can be put in place at the corresponding edentulous area to achieve balance. By doing so, a stable occlusion can be achieved. For this case report, a patient with crossed occlusion after extraction was treated with maxillary RDP (removable dental prosthesis) and mandibular implant-supported RDP (removable dental prosthesis). Moreover, an implant fixture was placed under the posterior molar of the distal extension base diagonally across from the remaining maxillary teeth. Then, magnetic attachment was implemented. According to the patient who received the treatment, the result was functionally and aesthetically satisfactory.

$SnO_2-CoO$/carbon-coated CoO core/shell nanowire composites were synthesized by using electrospinning and hydrothermal methods. In order to obtain $SnO_2-CoO$/carbon-coated CoO core/shell nanowire composites, $SnO_2-Co_3O_4$ nanowire composites and $SnO_2-Co_3O_4$/polygonal $Co_3O_4$ core/shell nanowire composites are also synthesized. To demonstrate their structural, chemical bonding, and morphological properties, field-emission scanning electron microscopy, transmission electron microscopy, X-ray diffraction, and X-ray photoelectron spectroscopy were carried out. These results indicated that the morphologies and structures of the samples were changed from $SnO_2-Co_3O_4$ nanowires having cylindrical structures to $SnO_2-Co_3O_4/Co_3O_4$ core/shell nanowires having polygonal structures after a hydrothermal process. At last, $SnO_2-CoO$/carbon-coated CoO core/shell nanowire composites having irregular and high surface area are formed after carbon coating using a polypyrrole (PPy). Also, there occur phases transformation of cobalt phases from $Co_3O_4$ to CoO during carbon coating using a PPy under a argon atmosphere.

154kV 디지털변전소 준공을 위한 엔지니어링 및 수행결과 분석에 관한 연구

이유진,한정열,최종기,이남호,Lee, You-Jin,Han, Jeong-Yeol,Choi, Jong-Kee,Lee, Nam-Ho 한국조명전기설비학회 2016 조명·전기설비학회논문지 Vol.30 No.12

In June 2013, 154kV digital substation based on IEC61850 was established for the first time in South Korea. In 2016, digital substation of about 26 plants have operated all over the nation. A new technology called IEC61850-based substation automation successfully applied to a real system. Since the early 2000s, to apply a new technology called IEC61850-based substation automation successfully to a real system, we (KEPCO) have been developing the engineering and performance verification technology related to fields. In this paper, we illustrate our engineering experience with the contents of the analysis and verification results, also various field problems that have occurred in the field during the past years. Finally we suggest a useful information that can be considered when the new substation is installed.

Recently, mobile devices have been widely used. Therefore, the service users want that are not constrained by time and space. Among them, electronic payment services, mobile finance service is enjoying a tremendous popularity. The FinTech is the result of the fusion of finance and ICT(Information & Communication Technology). Security experts is pointed the FinTech security risk. New technology and Innovative FinTech services are even available, Insecure FinTech services is insignificant. In this paper we were surveyed market and product trends of FinTech and analyzed the threats about FinTech. Also, we analyzed the security considerations for FinTech using a questionnaire. As a result, users considers secure payment process and privacy. Therefore, we proposed security considerations for each vulnerability. So, we must be resolved of security technology and policy issues. If establishing a secure payment process and the unclear legal issue is resolved, FinTech service will provide a secure financial services to the user.

이유진,Lee, You-Jin 한국디지털정책학회 2021 디지털융복합연구 Vol.19 No.8

연구 목적은 20대 금융 애플리케이션 사용자의 비대면 글말 용언으로부터 사용자 경험 디자인(UX)의 확장 의미를 추출하는 데 있다. 연구 범위는 20대 남녀 20명의 비대면 글말 일상 언어이며, 연구 방법은 사용자의 용언을 중심으로 사용 속성을 범주화(Categories)하여 20대 사용자 중심의 의미를 도출하는 것이다. 연구 결과 20대 금융 플랫폼 애플리케이션 사용자의 사용 의미는 통합의 의미, 신뢰의 의미, 지속의 의미, 정보 인지와 정보 접근의 의미로 요약되었다. 또한, 사용자의 사용 속성은 보안성, 친숙성, 접근성, 작동 편이성, 시인성으로 집약되었다. 각각의 속성은 보안, 정보, 브랜드, 디자인과 융합된 의미 범주에서 나타났다. 종합하면, 용언 중심의 사용자 의미 분석은 기존의 객관적 의미 분별 측정에서 파악할 수 없었던 사용성 평가 문제를 보완하는데 효과적임을 알 수 있었다. The purpose of the study was to induce meaning of the UX design from users' interview. The study covers interviews from 20 untact finance application users in their twenties in written form. It aims to examine previous studies on UX design and to overcome their shortcomings by categorizing usability qualities focusing on verbs used in the interview. The followings are the result: Usability of UX design can be summarized into Unity, Trust, Persistency, Recognition and Approachability of the information to the 20 users in their twenties. As for the data earned from interviews focusing on verbs, usability included Security, Familiarity, Accessibility, Convenience of Operation and Visibility. Each of the qualities fell into related categories such as Security, Information, Brand and Design. In conclusion, analysis based on verb choices led to better understanding of the user-based experience compared to using objective means in previous studies and can be a suggestion to make up for errors in the former evaluation process.

Sleep-related behaviors observed in parasomnias can result in serious injuries of patients and/or spouses. Parasomnia is defined as undesirable physical or behavioral phenomenon occurring during sleep. If these disorders are accurately diagnosed, effective treatments are available. Often, these disorders can be even cured. Environmental management for patient and/or spouse safety and good sleep hygiene are the most recommended for individuals behaving abnormally during sleep. The aim of this article is to review the clinical features, diagnosis and treatment of several sleep-related behavior disorders.
