Ji?Wook Jung,Sa?Rang Oh,Eun?Mi Ahn,Eun?Ju Yang,Su?Jin Kim 대한의생명과학회 2013 Biomedical Science Letters Vol.19 No.3

Ulcerative colitis (UC) is an inflammatory bowel disease, which is a chronic gastrointestinal disorder. Adenophorae Radix (AR) has been used as a traditional medicine for various diseases including strengthening cardiac function, allaying a fever, and easing pain and cough. However, the regulatory effects of AR in intestinal inflammation are not yet understood. This study attempted to determine the effect of AR in dextran sulfate sodium (DSS) ? induced colitis in mice. The colitis mice were induced by drinking water containing 5% DSS for 7 days. The results showed that mice treated with DSS showed remarkable clinical signs, including weight loss, and reduced colon length. Administration of AR attenuated weight loss, colon shortening and inhibited the levels of interleukin (IL) ? 6 in DSS ? treated colon tissues. These results provide experimental evidence that AR might be a useful therapeutic medicine for patients with UC.

Theory of mind is a capacity for making inferences our own and others' view or mind set, and for understanding the relationship between experiences, internal states and behaviors. It is also a necessary ability to maintain a successful social life. That is to say, this capacity for inferring what others think, feel, wish, want, intend, and believe plays a critical role for human social interactions. Theory of mind has been lively reported in foreign studies since 1980's, but domestic researches have not been interested in theory of mind until recent years. Thus, the purpose of this study is to investigate the ongoing research patterns, future research directions, and educational implications for early childhood education of theory of mind in Korea. The majority of studies on theory of mind in Korea was about effects of factors-socioeconomic status, child's social competency, emotion, language and story-making ability and pretend- on the development of theory of mind. But these studies aren't abundantly and have not been conducting diversely in contents. Therefore, studies on theory of mind will be activated, future studies should be not only more empirical and practical in various fields but also be in depth.

Early repolarization is a common electrocardiographic (ECG) feature found in young adults, men and athletes, and has been considered to be a benign feature for the last several decades. But recent studies suggest that early repolarization may be related to idiopathic ventricular fibrillation and sudden cardiac death. We report a young man, 35 years old, who had life threatening ventricular fibrillation and sudden cardiac arrest. He was evaluated for cardiac causes of ventricular fibrillation. There was no explanation other than that his ECG showed an early repolarization pattern so we treated him with implantable cardioverter defibrillator. Thus, we suggest that early repolarization may be related with life threatening ventricular arrhythmia.

온라인 아동 성착취 근절을 위한 법률개정 방안 : 국제규범과 국내 법령의 비교를 중심으로

정주은,남장현,서지혜 이화여자대학교 법학전문대학원 2020 Ewha Law Review Vol.10 No.-

온라인을 기반으로 한 아동ㆍ청소년에 대한 성착취는 아동ㆍ청소년이 쉽게 유혹되고 어른들에 의하여 발견되는 것이 어렵기 때문에 심각한 피해를 야기한다. 본 연구는 온라인 아동 성착취의 심각성을 인지하고 관련 법령의 개정 방안을 제시하고자 하였다. 우선 우리나라의 아동ㆍ청소년의 성보호에 관한 법률 및 형법 등의 법제 및 현황과 문제점을 살펴보았다. 이를 기반으로 UN아동권리협약 및 제2, 제3선택의정서와 UN아동권리위원회의 권고사항 및 특별보고관의 권고, 팔레르모의정서, 란사로테협약 등 국제규범의 내용을 살펴보고, 해당 국제규범과 해외의 입법례 등과 비교하여 현행 국내 법령의 개선방안을 모색하였다. 연구를 통해 현행 국내 법령의 부적절한 용어 개선이 필요하고, 아동 최선의 이익 원칙에 의한 법 해석 및 적용을 해야 하며, 현행 형법을 활용함과 동시에 그루밍 등 새로운 개념에 대하여 법률에 규정해야 함을 발견하였다. 이와 더불어 성착취물 등에 대한 처벌을 확대하고 형량과 양형기준을 개선하여야 할 필요성도 절감하였다. 현재 국회에 계류 중인 법률개정안을 검토하여 해당 법률안에서 주목할 점과 보완할 점에 대하여 설시하였다. 보론으로는 함정수사의 도입과 제3선택의정서 비준의 필요성을 주장하였다. 이에 비추어 볼 때, 최근 일련의 사건 이후 아동ㆍ청소년의 성보호에 관한 법률이 많은 부분에서 긍정적인 방향으로 개정되었지만 보호의 대상인 아동ㆍ청소년에 대한 범죄이므로 더욱 엄중히 처벌해야할 필요필요가 있는바, 국제규범에 따라 아동ㆍ청소년의 성보호를 위한 개정이 더욱 필요함을 시사한다. Online child sexual exploitation leads to serious damage because children and juveniles are easily tempted but it is hard for adults to find the breeding ground for crime. This study was intended to recognize the seriousness of online sexual exploitation for children and juveniles and to propose the law amendment. First of all, we explored the current status and problems of the legislation, such as the Act on the Protection of Sex in children and juveniles and the Criminal Law in the Republic of Korea. We reviewed the contents of international rules such as the U.N. Convention on the Rights of the Child, the Second and Third Choice Protocol, the recommendations of the U.N. Commission on the Rights of the Child, the recommendations from the CRC and special rapporteur, the Palermo Protocol, the Lanzarote Convention. In accordance with those international rules, we sought the amendment of current domestic law. According to the study, we concluded that the inappropriate terms in the current domestic law should be modified, and the law should be interpreted and applied in accordance with the principle of the best interests of children. Also, new concepts such as ‘grooming’ should be stipulated in the law while utilizing the existing Criminal law. In addition, we were faced with the necessity of expanding punishment for sexual exploitation and improving sentencing guidelines. We reviewed the proposition which was pending in the National Assembly and suggested pros and cons. And then, we complementally argued for the institution of entrapment and the ratification of the Third Choice Protocol.

Microstructures and Mechanical Properties of Multiphase‑Reinforced In Situ Aluminum Matrix Composites

Ju‑Hye Kim,Jae‑Gil Jung,Eun‑Ji Baek,최윤석,Kwangjun Euh 대한금속·재료학회 2019 METALS AND MATERIALS International Vol.25 No.2

We investigated the microstructures and mechanical properties of multiphase-reinforced in situ aluminum matrix composites(AMCs) prepared with various combinations and contents of Li, Mg, Si, Cu, Zn, Sn, and Ni. The area fractions of thesecondary phases in the as-cast AMCs ranged from 26% to 58%, and the types of secondary phases depended on the alloychemical compositions. The type and amount of secondary phases were more important than matrix strengthening in determiningthe alloy mechanical properties. Composite hardness and compressive stress increased while fracture strain decreasedwith increasing total area fraction of the secondary phases up to 40%. The formation of coarse primary and soft/heavySn-containing phases significantly deteriorated the alloy mechanical properties. Annealing also influenced the mechanicalproperties of the AMCs by changing the microstructures of the secondary phases and Al matrices.

Anthony Browne 그림책의 상호 텍스트성에 관한 연구

지은주,이혜은 부산유아교육학회 2003 유아교육논총 Vol.12 No.-

현대의 그림책에서는 여러 다양한 기법들이 사용되는데, 상호텍스트성도 이 중의 하나이다. 본 연구에서는 상호텍스트성을 문학적 또는 문학외적인 텍스트와 이미지의 변형 및 재구조화로 정의 내리고, Anthony Browne의 그림책을 이러한 상호텍스트적인 관점에서 분석하였다. 분석결과는 다음과 같다. 첫째, Anthony Browne의 그림책 속에는 전래동화와 신화가 숨어 있으며, 둘째, Anthony Browne의 그림책은 문학외적인 장르 즉 유명한 회화 작품들과 영화 장면들과도 상호텍스트성을 보이며, 넷째, Anthony Browne의 그림책들 간에도 인물, 배경, 스타일면에서 많은 상호텍스트성을 보인다. 이러한 상호텍스트성은 그림책을 훨씬 더 다양하고, 복합적이고, 재미있게하며, 아동으로 하여금 문학을 더욱더 확장하고 심화하게끔 한다. A variety of techniques are used in modern picturebooks, and one of these is intertextuality. We defined intertextuality as literary or extraliterary variation and restructure of text and image. We analysed Anthony Browne’s picturebooks in terms of intertextuality. Our results are followings: First, fairy tale and myth are linked with intertextuality in his books. Secondly, intrtextuality appears with extraliterary, well-known pictures and film-scenes. In the third, intertextuality appears on characters, settings, and style. Intertextuality makes children read picturebooks with very various, complex, and interesting mind, Then, intertextuality also helps children extend and deepen their understanding and imagination of the literature.

Purpose: The purpose of this study was to investigate the relationships between the degree of smart phone addiction among adolescents and their depression and anxiety levels. Method: In this study, 379 high school students were selected using the convenient sampling method. The instruments used for this study were smart phone addiction measure, the CES-D (Center for Epidemiological Studies-Depression Scale), and the STAI (State-Trait Anxiety Inventory). Data were analyzed using the SPSS 20.0 program with descriptive statistics, t-test, ANOVA with Scheffe test, and Pearson’s correlation coefficient. Result: The mean score for smart phone addiction was 40.45±17.27, depression was 36.56±9.58, state anxiety was 44.00±9.61, and trait anxiety was 45.70±9.75. There were significant differences between the degree of smart phone addiction and the following variables: gender (t=-4.953, p<.001), hours of smart phone use per day (F=12.259, p<.001), types of frequently used features (F=3.485, p=.008), and satisfaction level for smart phone (F=5.18, p<.001). There were statistically significant relationships (p<.001) among degree of smart phone addiction, depression level, and state and trait anxiety levels. Conclusion: The results of this study suggested that there was a significant relationship between smart phone addiction and mental health, specifically, depression and anxiety among adolescents. Further research is needed to develop nursing strategies to provide care for adolescents who frequently utilize smart phones.

Purpose: To develop the patient classification system based on the resource utilization for reimbursement of long-term care hospitals in Korea. Method: Health Insurance Review & Assessment Service (HIRA) conducted a survey in July 2006 that included 2,899 patients from 35 long-term care hospitals. To calculate resource utilization, we measured care time of direct care staff (physicians, nursing personnel, physical and occupational therapists, social workers). The survey of patient characteristics included ADL, cognitive and behavioral status, diseases and treatments. Major category criteria was developed by modified delphi method from 9 experts. Each category was divided into 2-3 groups by ADL using tree regression. Relative resource use was expressed as a case mix index (CMI) calculated as a proportion of mean resource use. Result: This patient classification system composed of 6 major categories (ultra high medical care, high medical care, medium medical care, behavioral problem, impaired cognition and reduced physical function) and 11 subgroups by ADL score. The differences of CMI between groups were statistically significant (p<.0001). Homogeneity of groups was examined by total coefficient of variation (CV) of CMI. The range of CV was 29.68-40.77%. Conclusions: This patient classification system is feasible for reimbursement of long-term care hospitals.

The purpose of this study was to investigate the patterns of the health related variables, and physical characteristics and physical fitness of the elderly people in order to provide a exercise program. The data about the health related variables were collected through the personal interview, and the data about physical charateristics and physical fitness (height, weight, % body fat, blood pressure, pulse rate, grip stength, trunk flexion, side step test, 2 min, harvard step test) of 373 elderly people living Seoul and kyungkee area were collected. The conclusions of this study can be summarized as follow; 1. The test results about smoking, drinking, sleeping and self-evaluation of health revealed that the elderly people have self-confidence about their health. 2. Not many elderly people participate the proper exercise program even though they recognize the need of exercise. 3. The results showed that the elderly people do not pay much attention to the intensity of the exercise. 4. Muscle strength training for leg and the lower back and cardio-vascular endurance training was recommended to reduce the risk of varius problems caused by aging. 5. A exercise program was suggested for the elderly people.
