Purpose : To promote awareness and efforts by pediatricians to identity and prevent child abuse by investigation of characteristics of victim and types of injury caused by abuse. Methods : A retrospective study was performed with 20 patients who had been diagnosed or suspected as child abuse at Hallym University Hospital from January 1999 to December 2005. The medical records, radiologic documents, and social worker's notes were reviewed to investigate age, sex, visiting time, form of abuse, perpetrator, risk factor, and type of injury. Results : The mean age of the subjects was 2.8 years. Fourteen patients were between 0-1 years old, 2 patients between 1-6 years old, 3 patients between 7-12 years old, and 1 case over 13 years old. The ratio of male to female was 1:1. The majority of these patients (70%) visited via emergency department. Eight five percent of these patients reported with physical abuse, 5% psychological abuse, 5% sexual abuse, and 5% neglect respectively. The suspected perpetrator was the biological father in six cases, the biological mother in three cases, the stepmother in two cases, caregiver in one case, relatives in one case and "unknown" in six cases. Bruise and hematoma (80%) were the most common physical findings. Skull fractures were diagnosed in six cases, long bone fractures in two cases, hemoperitoneum in two cases, subdural hemorrhage in 10 cases, epidural hemorrhages in two cases, subarachnoidal hemorrhages in two cases, and retinal hemorrhages in five cases respectively. Seventeen cases required hospitalization and surgical operations performed were in nine cases. Four patients died and three patients had sequalae such as developmental delay and quadriplegia. Conclusion : Child abuse results in high mortality and morbidity in victims. Therefore early recognition and prevention is very important. Pediatricians should always suspect the possibilities of abuse in cases of fracture, intracranial hemorrhage, abdominal injury, or even any injury to the body. We recommend that the clinical investigation of suspicious children should include a full multidisciplinary social assessment, a skeletal survey and CT or MRI.

Purpose : Recurrent otitis media (ROM) is usually defined as ${\geq}$3 distinct and well-documented episodes within 6 months or ${\geq}$4 episodes within 12 months. ROM is sufficiently important to warrant consideration of chemoprophylaxis, tympanostomy tube placement. There also is evidence that children with ROM are at risk for both hearing loss and speech delay. However, studies of ROM have been notably insufficient. In addition, even though environmental, racial, and sociocultural differences can affect risk factors, few studies have been conducted with regard to recurrent otitis media in Korea. Methods : This study was conducted from July 2009 to January 2010 with infants and children who were younger than 60 months old, who visited the out-patient clinics at Han-Il General Hospital and Kyunghee University Hospital. Data were collected by interview using a pre-formed sheet. Among a total of 892 infants and children, 457 were excluded, and the remaining 435 were allocated to 104 with ROM and 331 as a control group. Results : Attendance at daycare centers (P<0.001, OR=2.85), allergic rhinitis (P=0.026, OR=2.32), past history of bronchiolitis (P=0.003, OR=2.33), and low socioeconomic status (P=0.005, OR=2.00) were found to have a close significant correlation with ROM. Risk factors such as sex, having a sibling, breast-feeding, use of pacifiers, atopy, pneumococcal vaccination, influenza vaccination, smoking of parents, and indoor smoking are not relevant. Conclusion : Attendance at daycare centers, allergic rhinitis, past history of bronchiolitis, and low socioeconomic status have been identified as risk factors for ROM.

At first there was practice, then festivals and theory followed. Compared to the animation production, which is older then the medium film itself, festivals and theory in this area started with a delay. While animation programs where shown in film festivals like Cannes since the mid 1940s, the first animation festival in Annecy, France was founded in 1960, followed by several short-lived events in Romania, Italy and Tokyo and finally in 1972 by the second oldest festival up to date, Animafest Zagreb. Animation theory evolved in the late 1980s in the Anglo-American area with associations like the Society for Animation Studies, following its 'big sister' film studies. Expanding ever since as a research area, European animation studies in e.g. France, German speaking countries, Poland or Croatia have been catching up in recent years by organizing theoretical conferences and publications. A vivid synergy between practice, festivals and theory has always been a key factor for establishing a platform for the art form and culture of animation. However, in the past few years a trend could be observed towards a more intense interaction between animation festivals and theory. Animation festivals are hosting theoretical and scientific symposia or conferences, which are open for artist positions and insights into the industry. At the beginning of the lecture a short reflection of the concept of Animafest Scanner itself is followed by an introduction of the Symposium Expanded Animation at the media festival Ars Electronica Linz. The talk will subsequently focus on the multilayered academic symposia at the Festival of Animated Film ITFS and the International Conference on Animation, Effects, VR, Games and Transmedia in Stuttgart. These case studies will reveal the blurring boundaries between art, science, theory and industry as well as the specificities of the interplay between artists, practitioners, scholars, curators and festival visitors in different formats.

This study was designed to evaluate the anti-obesity and hypoglycemic effects of Gugija (Lycium chinense Mill) extracts in 3T3-L1 adipocytes. We investigated the $\alpha$-amylase and $\alpha$-glucosidase inhibitory activities of extracts from Gugija. Gugija was extracted by 70% EtOH and 80% MeOH and aqueous, respectively. A single oral dose of Gugija extract inhibited the increase of blood glucose levels significantly at 0, 30, 60, 90 and 120 min and decreased incremental response areas under the glycemic response curve. These results suggest that Gugija 70% EtOH extracts may delay carbohydrate digestion and reduce postprandial hyperglycemia. In addition, triglyceride content in 3T3-L1 adipocytes decreased at higher concentrations of Gugija 70% EtOH extract. Free fatty acid content in 3T3-L1 adipocytes was increased at higher concentrations of Gugija 70% EtOH extract. Also, glucose transporter 4 (GLUT4), the key insulin signaling pathway transcription factor, was remarkably increased by the Gugija 70% EtOH extract when compared to those of control cells in protein expression levels. Therefore, Gugija can be developed as an effective anti-obesity and hypoglycemic agent.

China is experiencing rapid economic development and the volume of air passengers and cargo transportation has increased significantly in recent years. To the contray, the regulations on liability of air carrier in china fall behind and are not sufficiently applicable in disputes. Their lack of sufficient protection for air passenger's interests became obstructive factor for further developments of Chinese air transportation industry. The legal system of air carrier's liability mainly consists of the contents as followed. The liability period, the scope of liability, amount of compensation for damage, limitation of liability, liability exemption of air carrier, jurisdiction, limitation of action, applicable law etc. Laws and rules concerning these issues are regulated in Civil Aviation Law and regulations published by Civil Aviation Administration of China. This article described the main contents of air carrier's liability and examined the legislative problems in their applications in real cases. In order to solve the legal problems on the air carrier's liability and disputes between wrongdoers and survivors etc, it is necessary and desirable for china to amend revelvant provisions. One of my proposals is to raise the amount of compensation limitation for damage. And I also would like to suggest that Civil Aviation Law should treat international and domestic transportation equally on the limitation of compensation for air carrier's liability. China has also acceded to the Montreal Convention of 1999 on July 31, 2005. This is an effort to make the law of air carriage unified worldwide through various international conventions to achieve conformity between rules of international air carriage and that of Chinese domestic aircarriage. Furthermore, there should be additional detailed implementation rules for air carrier to assume liability for the losses to passengers, baggage or cargoes caused by delays in the air transport. Significant clarifications are also needed for provisions concerning whether and how air carrier assume liability for moral damage caused by accident.

Objectives：Developmental reading disorder is a condition which manifests significant developmenttal delay in reading ability or persistent errors. About 3-7% of school-age children have this condition. The purpose of the present study was to validate the diagnostic values of Word/Nonword Reading Test and Letter-Symbol Discrimination Task for the purpose of overcoming the caveats of Basic Learning Skills Test. Methods：Sixty-three reading-disordered patients(mean age 10.48 years old) and sex, age-matched 77 normal children(mean age 10.33 years old) were selected by clinical evaluation and DSM-IV criteria. Reading I and II of Basic Learning Skills Test, Word/Nonword Reading Test, and Letter-Symbol Discrimination Task were carried out to them. Word/Nonword Reading Test：One hundred usual highfrequency words and one hundred meaningless nonwords were presented to the subjects within 1.2 and 2.4 seconds, respectively. Through these results, automatized phonological processing ability and conscious letter-sound matching ability were estimated. Letter-Symbol Discrimination Task：mirror image letters which reading-disordered patients are apt to confuse were used. Reliability, concurrent validity, construct validity, and discriminant validity tests were conducted. Results：Word/Nonword Reading Test：the reliability(alpha) was 0.96, and concurrent validity with Basic Learning Skills test was 0.94. The patients with developmental reading disorders differed significantly from normal children in Word/Nonword Reading Test performances. Through discriminant analysis, 83.0% of original cases were correctly classified by this test. Letter-Symbol Discrimination Task：the reliability(alpha) was 0.86, and concurrent validity with Basic Learning Skills test was 0.86. There were significant differences in scores between the patients and normal children. Factor analysis revealed that this test were composed of saccadic mirror image processing, global accuracy, mirror image processing deficit, static image processing, global vigilance deficit, and inattention-impulsivity factors. By discriminant analysis, 87.3% of the patients and normal children were correctly classified. Conclusion：The patients with developmental reading disorders had deficits in automatized visuallexical route, morpheme-phoneme conversion mechanism, and visual information processing. These deficits were reliably and validly evaluated by Word/Nonword Reading Test and Letter-Symbol Discrimination Task.

The growth of Italian ryegrass (IRG) after wintering was very low in 2015 when IRG was broadcasted under growing rice in fall of 2014. To determine growth inhibitory factors of IRG, we examined the growth conditions of IRG in Nonsan region and meteorological conditions in Daejeon nearby Nonsan. Minimum temperature and maximum instantaneous wind speed on Feb. $8^{th}$ and $9^{th}$ of 2015 after wintering of IRG were $8.8^{\circ}C$, 10.7 m/s and $12.4^{\circ}C$, 9.6m/s, respectively. Air temperature was suddenly dropped due to strong wind with snow showers, which had unfavorable effect on root growth of IRG exposed at the soil surface. The minimum temperature and maximum instantaneous wind speed on Feb. $12^{th}$, $13^{th}$, and $14^{th}$ of 2015 were $4.1^{\circ}C$, 11.6 m/s, $-5.6^{\circ}C$, 10.3 m/s, and $-4.7^{\circ}C$, 7.5 m/s, respectively. The growth circumstance of IRG was not good because soil was dried due to drought continued from January. The minimum temperature and maximum instantaneous wind speed on Feb. $26^{th}$, $27^{th}$, and $28^{th}$ of 2015 were $1.8^{\circ}C$, 13.7 m/s, $-3.5^{\circ}C$, 10.6 m/s, and $4.1^{\circ}C$, 6.8 m/s, respectively. The number of wilting of IRG was more than 59% until Mar. $3^{rd}$ of 2015. IRG faced irreparable environment (low minimum temperatures and extreme instantaneous wind speeds) for 9 days from Mar. $4^{th}$ to Mar. $12^{th}$ of 2015. The main reason for the decrease of IRG productivity was collection delay of rice straw after rice harvest because there was continuous rain between Oct. and Nov. of 2014. For this reason, weakly grown IRG under rice straw was withered after wintering. IRG was withered by frost heaving, drought, and instantaneous wind speed in the spring. Furthermore, the root of IRG was damaged while growing in excess moisture in the surface of paddy soil during the winter season due to rain.

Background : The causes of chest pain vary but the leading cause of chest pain is ischemic heart disease. Mortality from ischemic chest pain has increased more than two fold over the last ten years. The purpose of this study was to determine the data necessary for rapid treatment of patients with signs and symptoms of ischemic chest pain in the emergency department (ED). Materials and Methods : We interviewed 170 patients who had ischemic chest pain in the emergency department of Yeungnam University Hospital over 6 months with a protocol developed for the evaluation. The protocol used included gender, age, arriving time, prior hospital visits, methods of transportation to the hospital, past medical history, final diagnosis, and outcome information from follow up. Results : Among 170 patients, there were 118 men (69.4%) and the mean age was 63 years. The patients diagnosed with acute myocardial infarction (AMI) were 106 (62.4%) and with angina pectoris (AP) were 64 (37.6%). The patients who had visited another hospital were 68.8%, twice the number that came directly to this hospital (p<0.05). The ratio of patients who visited another hospital were higher for the AMI (75.5%) than the AP (59.4%) patients (p<0.05). The median time spent deciding whether to go to hospital was 521 minutes and for transportation was 40 minutes. With regard to patients that visited another hospital first, the median time spent at the other hospital was 40 minutes. The total median time spent before arriving at our hospital was 600 minutes (p>0.05). The patients who had a total time delay of over 6 hours was similar 54.8% in the AMI group and 57.9% in the AP group (p>0.05). As a result, only 12.2% of the patients with an AMI received thrombolytics, and 48.8% of them had a simultaneous percutaneous coronary intervention (PCI). In the emergency department 8.5% of the patients with an AMI died. Conclusion : Timing is an extremely important factor for the treatment of ischemic heart disease. Most patients arrive at the hospital after a long time lapse from the onset of chest pain. In addition, most patients present to a different hospital before they arrive at the final hospital for treatment. Therefore, important time is lost and opportunities for treatment with thrombolytics and/or PCI are diminished leading to poor outcomes for many patients in the ED. The emergency room treatment must improve for the identification and treatment of ischemic heart disease so that patients can present earlier and treatment can be started as soon as they present to an emergency room.
