Purpose : Child sexual abuse is a significant and serious problem that affects public health and society. Pediatricians are responsible for preventing and detecting sexual abuse of children. The aim of this study was to examine clinical findings of child sexual abuse. Methods : The authors retrospectively studied 292 patients between the ages of 0 and 18 who were referred for evaluation of sexual abuse to the Emergency Department of the National Police Hospital from Oct 1, 2001 to May 5, 2005. Results : Sixty three (21.6 percent) of sexual abuse victims were younger than 6 years of age; 89 (30.5 percent) were 6-12 years of age; and 104 (47.9 percent) were 12-18 years of age. Attack time was the most common between noon and 6 pm. Victims were attacked in their home or nearby (51.4 percent). One hundred fifty six (53.6 percent) offenders were accquaitances, thirty nine (13.4 percent) of whom were family members. The disclosure of attack by parents with abnormal physical symptoms was more common in younger children than in adolescence. Eighty nine (30.5 percent) victims had no specific physical findings, 51 percent had injury to the hymen, 37.3% had injury to external genitalia, and 4 percent had anal injury. One case of gonorrhea and thirteen cases of chlamydia were found. Sperm was found in 19 cases and acid phosphatase was positive in 28 cases. The absence of physical findings and laboratory findings was more common in younger children than in those in adolescence. The time interval from attacks to hospital visits had a significant negative correlation with age. Conclusion : For younger victims, the time interval from attack to hospital visitis was more prolonged. Victims may have no physical evidence of sexual abuse. Therefore, a careful history should be obtained and a through physical examination should be performed. Pediatricians must play a leading role in evaluation and treatment of sexually abused children, considering children,s growth and development. Coordination with other professionals is necessary to provide consultation, medical treatment, and legal assistance for the sexually abused children and families.

Cholpyon, a traditional Korean rice cake, was prepared using pigmented rice and the quality characteristics them were compared with Cholpyon made of brown and white ice during 24 hr storage at 20$\^{C}$. In proximate composition, crude protein contents were not significantly different among three rice varieties whereas the contents of crude lipid and ash in pigmented and brown rice were higher than that of white rice. In mechanical characteristics, 100% pigmented rice Cholpyon showed lower values for hardness, cohesiveness, springiness and chewiness, and higher value far adhesiveness compared with those of white rice Cholpyon. These results were maintained for 24 hours. Sensory Characteristics of 100% pigmented rice Cholpyon such as color, hardness and overall quality were better than those of white rice Cholpyon. Brown rice Cholpyon had similar mechanical properties to 100% pigmented rice Cholpyon, but showed the lowest preference in color.

With the rapidly increasing demand of traffic applications, the need to support seamless and robust multimedia services in the Vehicular Ad hoc Network is growing. Fast handover for the MIPv6 (FMIPv6) developed to solve the MIPv6's problem as well as Mobile IPv6 (MIPv6) for basic mobility protocol have been developed to support seamless handover in mobile environment. However, MIPv6 and FMIPv6 are useless for Quality-of-Service (QoS) services such as multimedia applications due to the long handover latency and the packet loss problem. In this paper, we propose a seamless and robust handover scheme that supports multimedia services in Vehicular Ad hoc Network using oCoA and background DAD. Through performance evaluation, we show that the proposed scheme is more proper for Vehicular Ad hoc Network than other schemes.

In this paper, we propose a high-performance BICS(built-in current sensor) which is fabricated in 0.8${\mu}{\textrm}{m}$ single-poly two-metal process for IDDQ testing of CMOS VLSI circuit. The CUT(circuit under test) is 4-bit full adder with a bridging fault. Using two nMOSs that have different size, two bridging faults that have different resistance values are injected in the CUT. And controlling a gate node, we experimented various fault effects. The proposed BICS detects the faulty current at the end of the clock period, therefore it can test a CUT that has a much longer critical propagation delay time and larger area than conventional BICSs. As expected in the HSPICE simulation, experimental results of fabricated chip demonstrated that the proposed BICS can exactly detect bridging faults in the circuit.

Intramural hematoma of the aorta (IMH) is the precursor or a variant of a classic aortic dissection where hemorrhage occurs within the aorta wall in the absence of an initial intimal tear. IMH has a high rate of mortality and morbidity. The optimal therapy for IMH is uncertain, yet the involvement of the ascending aorta is usually considered as an indication for surgery due to the associated risk of rupture or cardiac tamponade. We report here on a case of a 71-year-old man who presented with syncope. Because of misdiagnosis, he underwent computed tomography (CT) after 5 hrs from arriving to the ER. Computed tomography of the aorta revealed intramural hematoma of the ascending aorta with cardiac tamponade. He also had vascular complications such as acute renal failure and visceral ischemia. We performed emergency graft replacement of the total arch and ascending aorta. He was discharged without complication on postoperative day 14.

The purpose of this study is to describe the SW Convergence education class applying the Novel Engineering teaching method during the creative experiential activity time. We developed a SW convergence education program for a patriotism class applying Novel Engineering, a new educational method instead of writing and drawing. Through this lesson program, students can improve their problem-solving ability based on their computational thinking and enhance their love spirit about country. Students read a book that tells the story of patriot, writes the historical scene presented in the book through scenarios through Re-enactment, and implements the simulation situation using Lego WeDo 2.0. The results of this study based on the analysis of the data on the questionnaire showed that there is a significant students' change through the SW convergence education program for patriotism class. In the future, we will expand the scope to more various grades and subjects so that we can generalize the effectiveness of SW convergence education applying Novel Engineering.

The purpose of this research is to analyze how the Chinese cosmetics certification system works as a Non-Tariff Barriers(NTBs) for Korean exporting companies to access the Chinese market. China is the largest market for Korea's cosmetic exports, but China's policy of protecting domestic industry has become a barrier to Korea's cosmetics exports to China. Therefore, this research, through the analysis of regulations of the Chinese certification system for imported cosmetics. revealed that there are such problems as ① information leakage ② duplication of inspection ③time delay. In order to verify those problems, surveys and face-to-face interviews with Korean cosmetic exporting companies to China have been conducted. In conclusion, Chinese cosmetics certification system not only protects its own industry, but also serves as a NTBs to disturb the access of imported cosmetics to the Chinese market in order to foster Chinese cosmetic industry.

This study was conducted to investigate the effect of monosodium glutamate (MSG) and fermentation methods (C-I; fermented for 5 days at 1$0^{\circ}C$ after 2$0^{\circ}C$ fermentation for 2 days, C-II; fermented for 7 days at 1$0^{\circ}C$, M-I; kimchi with MSG fermented for 5 days at 1$0^{\circ}C$ after 2$0^{\circ}C$ fermentation for 2 days, M-II; kimchi with MSG fermented for 7 days at 1$0^{\circ}C$ on fermentation and free amino acid content. Fermentation of M-I and M-II was slightly delayed compared to C-I and C-II. Total microbe of C-I and C-IIwere lower than those of M-I and M-II, and lactic acid bacteria of C-I and C-II were lower than those of M-I and M-II respectively. The major free amino acids were alanine, asparagine, homocystine and valine in C-I, especially, glutamic acid and ornithine were high in C-II. Homocystine, alanine, asparagine and valine in M-I, glutamic acid, alanine, hydroxyproline, asparagine, homocystine, ornithine and valine were the major free amino acid in M-II, respectively. The sour taste of M-I and M-II was lower than those of C-I and C-II, respectively, and the effect of delaying fermentation at 1$0^{\circ}C$ did not showed in the C-I and M-I. The crispy taste of the M-I and M-II was higher than those of C-I and C-II, which was the opposite results of sour taste. Palatable and overall taste of M-I and M-II were higher than those of C-I and C-II, respectively These results suggest that the MSG in kimchi affect not only increment of free amino acid content but also shelf-life and taste improvement, and continuous fermentation at 1$0^{\circ}C$ also enhance the content of free amino acid and shelf-life of kimchi.
