Objective : Since Kawasaki disease was first described in 1967, the cause and prognostic factors have not been known despite many researches and efforts. The introduction of high-dose intravenous gamma-globulin (IVGG) was an epoch and IVGG is now a standard therapy. But the mode of action of IVGG in reducing inflammatory response is not clearly understood. Understanding of the mechanism should supply the clues that indicate the cause, prognosis, the better treatment of this disease. At present, the correlation of CRP, ESR and change of leukocyte numbers to Kawasaki diseases were known, but the correlation studies of ASO titers are rare. To discover this, we evaluated the interrelationship between the ASO titer and IVGG therapy. Methods and Materials : The subjects included 35 patients with Kawasaki disease who were treated by IVGG at department of pediatrics, Inje university, Busan Paik hospital from June, 2004 to December, 2005. Before and after IVGG administration, ASO titers were evaluated. Results: In the 32 among 35 patients, ASO titers checked before IVGG administration were increased prominently after IVGG therapy. Conclusion : Remarkably increased ASO titers after IVGG administration for the treatment of Kawasaki diseases were found. And changes of ASO titers seem to be due to immunoglobulin instead of streptococcal infection. Further studies will be necessary to clarify the pathogenic mechanisms of increased ASO titers.

황주성,유지연 한국정보사회진흥원 2007 정보화정책 Vol.14 No.1

본 연구는 우리나라의 인터넷 보급이 완료단계에 접어든 2002년과 3년 후인 2005년의 조사 자료를 토대로 국내 인터넷 활용의 전반적인 모습이 어떻게 변화하였고, 어떤 인구사회학적 집단이 그러한 변화를 주도하였는지를 밝히고자 하였다. 또한, 10여개의 주요 인터넷 활동별로 동일기간 동안의 변화양상과 변화주도 집단을 찾아냄으로써 인터넷 활용의 전체적인 모습과 변화추이를 살펴보았다. 분석결과, 지난 3년간 우리나라의 인터넷 활용은 이용도가 99.6%, 의존도와 일상화율도 각각 50.7%, 36.7%가 증가하여 동일기간 동안의 인터넷 접속율 22.6% 보다 전반적으로 높은 성장을 보여주었다. 성장을 주도한 인구사회학적 집단은 여성과 10, 20대가 두드러졌다. 지역의 경우 이용도와 의존도, 경험율에서는 중소도시 및 읍면지역이 상대적으로 높은 증가를 보인 반면, 일상화율에서는 오히려 서울 및 대도시지역이 더 높은 성장을 보였다. 인터넷 활동영역별로는 인터넷쇼핑, 시사정보, 일업무의 순으로 일상화율이 높았으며, 정규학습, 인터넷게임, 새로운 관계, 전자정부 등이 2002년에 비해 두 배 이상의 높은 증가율을 보였다. The study seeks to identify changes in overall picture of domestic Internet use and sociodemographic groups that led to that change based on the survey results of 2002, a period when the internet has become widely available and 2005. In addition to that, the study also examines general trends and changes in Internet use by pinpointing aspects of changes and groups leading the changes during the same period according to ten major Internet activities. As a result, Internet usage rate has increased by 99.6 percent in Korea over the last three years. Dependency rate and engagement rate have risen by 50.7 percent and 36.7 percent respectively, higher growth rates compared to Internet connection rate of 22.6 percent during the same period. The socio-demographic groups that took the lead in the growth have turned out to be women and people in their 10s and 20s. In regional perspective, small cities and rural areas have shown a relatively high growth in Internet use, dependency and experience while Seoul and the other large metropolitan areas have registered a steeper rise in engagement rate. In terms of Internet activities, e-shopping has recorded the highest engagement rate followed by current e-news and work-related use. e-school, online games, online friends and e-government have all grown twice as much as in 2002.

This study is focused on how much middle school students who learn the chapter of first-grade science, ‘The Materials and Change of the Earth Surface’, connect and understand what they learn with their environment and surroundings. According to this research, this study will discuss the connection between school education and living surroundings and how much the difference between the surroundings will influence the understanding of their concepts and attitudes toward science. This study researched 330 second-grade students in middle schools which are located in Jeonju, Buan and Jinan in Jeollabukdo. (1) In case of mineral and rocks, this study analyzed that students have known the concept of mineral and rocks by observing samples in class. Only 16 percent of the students observe surrounding rocks with interest, but most of them are not interested in it. (2) Chaesukgang and Mountain Mai are two local places in Jeollabukdo which have a lot of specific stratum and geological structures. So it’s easy for teachers to show the students rocks and geological structure by connecting outdoor experience with these locations. Although the students have a little more observation experience than Jeonju area students, all of them throughout the county seldom do outdoor observation learning. By collecting and observing the surrounding minerals and rocks, along with teaching the chapter ‘The Materials and Change of the Earth Surface’, and by visiting outdoor locations while teaching at geological structures, we can improve the effect of learning.

2.9%의 과산화수소를 함유한 시험용 부착형 미백제(Medison dental whitening strip, Samsung medical Co.,Anyang,Korea)를 실험군 피험자 23명, 시험용 미백제에서 과산화수소를 제외한 동일한 제재를 대조약으로 대조군 피험자 24명에게 매일 1시간 30분씩, 2주간 적용하여 임상적 효능과 안전성을 평가하였다. 미백 효과는 Shade Vision, Chroma Mete 및 Vitapan classical shade guide를 이용하여 색변화를 측정하여 다음과 같은 결론을 얻었다. 1. 실험군에서의 전체 치아의 색변화량(ΔE^(*))은 세 가지 측정법에서 모두 대조군에 비해 통계적으로 유의한 차이를 보였고 (p < 0.05). 쉽게 인지할 수 있는 정도였다. 2. 색변화는 색좌표 상에서 명도의 증가와 녹색조 및 청색조로의 변화에 의해 얻어졌다. 3. 치아별로는 어두운 견치의 색변화량이 가장 컸고, 측절치, 중절치 순으로 감소하였다. 4. 47명의 피험자 중 5명이 경도의 과민증을 경험하였으나 곧 완화되었다, 치은염증지수와 전기치수검사 결과 시험 전후에 차이가 없어 안전성을 확인하였다. This study evaluated the effectiveness and safety of an experimental bleaching strip (Medison dental whitening strip, Samsung medical Co., Anyang, Korea) containing 2.9% hydrogen peroxide. Twenty-three volunteers used the bleaching strips for one and a half hour daily for 2 weeks. As control group, the same strips in which hydrogen peroxide was not included were used by 24 volunteers with the same protocol. The shade chang (ΔE^(*), color differnce) of twelve anterior teeth was measured using Shade Vision (X-Rite Inc., S. W. Grandville, MI, USA), Chroma Meter (Minota Co., Ltd. Osaka, Japan) and Vitapan classical shade guide (Vita Zahnfabrik, Germany). The shade change of overall teeth in the experimental group was significantly greater than that in the control group (p < 0.05) and was easily perceivable. The change resulted from the increase of lightness (CIE L^(*) value) and the decrease of redness (CIE a^(*) value) and yellowness (CIE b^(*) value). The shade change of individual tooth was greatest in canine, can smallest in central incisor. The safety of the bleaching strip was also confirmed. 〔J Kor Acad Cons Dent 31(4):269-281, 2006〕

A high proportion of hazardous (PVC, asbestos, chlorinated solvents) and infection wastes are treated in incinerators, the high temperature and high energy characteristics of plasma may be employed to convert waste materials into inert small volume products and combustible gases, plasma torch melting(PTM) is one of the most widely used tool for the vitrification of wastes. The ash product generated is of low bulk density and may also contain leachable quantities of toxic heavy metal and organic species. Plasma processing is able to treat these ashes, destroying any contained polyaromatic hydrocarbons components. Also we presented a steady three-dimensional model for a plasma melting furnace optimum designed in this study with RNG k-ε model, and its use in characterizing the structure of the flow field, temperature field and reaction field. Among various types of plasma torches, non-transferred hollow cathode type torch is best suited due to its long lifetime, easy power controllability and steady power output. Development of a plasma torch showed the lifetime longer than 300 hours and efficiency better than 65% And the various factors(electrode diameter, cooling flow rate and temperature and gas flow rate affecting the thermal efficiency of the torch) were experimentally evaluated.

In recent years, gonorrhea has been pandemic and remains one of the most common STDs in the world, especially in developing countries. For the detection of a more effective therapeutic regimen and assessing the prevalence of Penicillinase Producing Neisseria gonorrhoeae(PPNG), we have been trying to study the patients who have visited the Venereal Disease Clinic of Choong-Ku Public Health Center in Seoul since 1980 by menas of the chromogenic cephalosporin method. In 1998, 93 strians of N. genorrhoeae were isolated, among which 60(64.5%) were PPNG. The prevalence of PPNG in Seoul, which had been decreased to 39% in 1996 after a peak of 74.3% in 1993, is increased to 64.5% in 1998.
