Introduction : In this study, the analgesic effect and its mechanism of bee venom aqua-acupuncture on complete Freund's adjuvant-induced arthritis in rats was investigated. It has been reported from a neurochemical standpoint that bee venom exerts antinociceptive effects on inflammation and that the opioid system and adrenergic system play important roles in acupuncture analgesia. however, it is not known whether central opioid and ${\alpha}2$-adrenergic components of the intrinsic descending analgesic system are activated after bee venom aqua-acupuncture. Methods : Bee venom(1mg/kg) was subcutaneously aqua-acupunctured into Joksamni($ST_{36}$) of rats with complete Freund's adjuvant(CFA)- induced arthritis and was checked of increase in TFL. Opioid and ${\alpha}_2$-adrenergic neurotransmitter system were examined by naloxone as an opioid receptor antagonist, and yohimbine as ${\alpha}_2$-adrenoceptor antagonist prior to bee venom aqua-acupuncture. Results : The following results have been obtained. 1. The tail flick latency in the rat model with adjuvant-induced arthritis was significantly decreased in 2 weeks. 2. The tail flick latency in the rat model with adjuvant-induced arthritis was increased in bee venom aqua-acupuncture group compared to the normal saline aqua-acupuncture group. 3. Analgesic effect of bee venom was antagonized by yohimbine not by naloxone pretreatment in the rat model adjuvant-induced arthritis. Conclusions : Bee venom aqua-acupuncture has an analgesic effect on the rat model of adjuvant-induced of adjuvant-induced arthritis and has antinociception mediated by ${\alpha}_2$-adrenergic system.

Objective : This study was designed to investigate the effects and adverse effects of Choweseuncheng-tang on obesity patients Methods : Choweseuncheng-tang was given to 20 obesity patients who have no abnormality of GOT, GPT and past medical history. Additionally, electroacupuncture was performed on Fuchao(腑巢) with 60Hz. We compared body weight, body fat and laboratoy test(GOT, GPT, BUN, Creatinine) between before and after treatment. Blood pressure, heart rate and clinical symptoms were checked to investigate the side effects. Decrease of body weight was checked in accordance with Sasang constitutional type, appetite type, and BMI. Results : 6 patients(BMI 23-24.9), 10 patiets(BMI 25-29.9), and 4 patients(BMI over 30) were showed decrease of body weight. We found body fat was decerased $3.16{\pm}1.25%$. BUN, Creatinine, GOT and GPT were increased within normal range. There were adverse event of autonomic hyperactivity(11 patients), gastrointestinal symptoms(7 patients) and others(3 patients). Conclusions : According to above results, Choweseuncheng-tang could be used effectively, but should be taken cautiously on obese patients.

차세대 모바일 콘텐츠 서비스를 위한 멀티미디어 인사말 시스템의설계 및 구현

서동민,유재수,조기형 한국콘텐츠학회 2005 한국콘텐츠학회논문지 Vol.5 No.2

As wireless internet market grows rapidly, demands of various contents in wireless internet are significantly being increased. The mobile contents have been changed from single media contents such as text and voice to multimedia contents. As the technologies of cellular phone and broadband grow, the development of multimedia contents that can well represent the characteristics of users will be more increased. One example of such content developments is a ring-tone content service. Ring-tone content services have been changed from existing simple ring-tone to various sound services that depend on characteristic of user. In this paper, we design and implement a multimedia greeting system for the next generation mobile content service. Our system produces multimedia greeting contents using various multimedia contents and represents the characteristics of users through the elevation of ring-tone content services. 무선 인터넷 시장이 급속히 성장함에 따라 모바일 콘텐츠에 대한 수요가 급증하고 있다. 사용자에게 서비스되고 있는 모바일 콘텐츠는 텍스트나 음성과 같은 단일 미디어 콘텐츠에서 멀티미디어 콘텐츠로 변화하고 있다. 향후 이동전화와 광대역 통신 기술이 발전함에 따라 개인의 개성을 보다 잘 표현할 수 있는 멀티미디어 콘텐츠 개발이 더욱 활발해 질 것이다. 이러한 콘텐츠 발전의 한 예로 통화연결음 콘텐츠 서비스를 들 수 있다. 통화연결음 콘텐츠 서비스는 기존의 단순한 통화연결음에서 개인의 취향에 따라 다양한 음악으로 변경해주는 서비스로 발전하였다. 본 논문에서는 차세대 모바일 콘텐츠 서비스를 위한 멀티미디어 인사말 시스템을 설계하고 구현한다. 제안하는 시스템은 통화연결음 콘텐츠 서비스를 발전시켜 개인의 개성을 나타낼 수 있도록 다양한 멀티미디어 콘텐츠를 이용하여 직접 멀티미디어 인사말을 제작한다.

B+-트리 기반의 이동객체 색인 기법

서동민,유재수,송석일 한국콘텐츠학회 2007 한국콘텐츠학회논문지 Vol.7 No.7

Applications involving moving objects require index structures to handle frequent updates of objects’ locations efficiently. Several methods to index the current, the past and the future positions of moving objects have been proposed for the applications. Most of them are based on R-tree like index structures. Some researches have made efforts to improve update performance of R-trees that are actually focused on query performance. Even though the update performance is improved by researchers’ efforts, the overhead and immaturity of concurrency control algorithms of R-trees makes us hesitate to choose them for moving objects. In this paper, we propose an update efficient indexing method that can be applicable for indexing the past, the current and the future locations. The proposed index is based on B+-Trees and Hilbert curve. We present an advanced Hilbert curve that adjusts automatically the order of Hilbert curve in subregions according to the data distribution and the number of data objects. Through empirical studies, we show that our strategy achieves higher response time and throughput. 이동객체 응용은 빈번하게 변경되는 이동객체의 위치정보를 효과적으로 처리할 수 있는 색인구조를 필요로 한다. 이동객체의 위치를 색인하기위해 제안된 색인기법들은 대부분 R-트리를 기반으로 하고 있다. R-트리는 변경 보다는 검색 연산의 성능에 초점이 맞추어진 색인구조이어서 잦은 변경을 다뤄야 하는 이동객체의 응용에 적합하지 않은 측면이 있다. 일부 연구에서는 R-트리의 변경 연산 성능을 향상시키기 위한 연구를 진행한 바 있다. 하지만, 변경 연산의 성능이 개선되었다 하더라도 R-트리가 기본적으로 내재하고 있는 동시성 제어기법 문제(동시성 제어 기법의 비효율성과 안정성) 때문에 R-트리 기반의 색인 기법을 실제 응용에서 쓰는 데는 여전히 문제가 있다. 이 논문에서는 B+-트리와 힐버트 곡선 (Hilbert Curve)를 기반으로 하는 새로운 이동객체 색인 기법을 제안한다. 기존에 제안된 B+-트리 기반의 색인 기법과는 다르게 이 논문에서는 힐버트 커브의 해상도(또는 차수, order)를 객체의 분포도와 개수에 따라서 가변적으로 적용하는 방법을 제안한다. 실험을 통해서 제안하는 색인 기법이 응답시간과 처리율 측면에서 기존 색인기법에 비해 우수함을 보인다.

To prevent global warming, a variety of governments are investing in electric vehicle research and especially in Korea, electric vehicle is trying to be applicable to public transportation. Lithium batteries used in electric vehicles such as mobile phone and laptops are mainly used and life cycle is expected to 1-2 year. If electric vehicles are used popularly, many discarded batteries will occur and it is harmful to the environment. In addition, lithium batteries are explosive in nature and should be treated cautiously. Therefore, reverse logistics is needed to handle the batteries efficiently and safely. Reverse logistics includes the collection, remanufacturing, recycling and discarding of the waste. In this study, reverse logistics process for electric vehicle batteries is developed through the analysis of the AS-IS process of the lead and lithium batteries. In addition, disposal regulations for electric vehicle batteries are proposed based on the current law of the waste of the conventional batteries.
