Objectives : The purpose of this study is to report the effectiveness of a Korean Medicine Treatment on 89 severe atopic dermatitis patients all through 12 months. Methods : The degree of atopic dermatitis was measured in Objective SCORAD Index (OSI) with photos of patients. Then, the OSI score was estimated according to gender, age and intensity. Results : 1. The ratio of male to female was 41.57 : 58.43. The 24.72% of patients were in 0~11 year-old group, 16.85% were in 12~18 year-old group and 58.43% were in the group above 19 years old. 2. The initial OSI score was 64.43 and the final was 37.03 after 12 months. After 3, 6, 9, 12 months, the OSI score was significantly lower than the initial visit. 3. There was no significant difference between male and female patients on age, OSI scores and OSI improvements. 4. The patients who treated acupuncture were significantly older then who not treated. The OSI improvement had no significant difference whether treated with acupuncture or not. 5. There was no significant difference among 3 different age groups on initial OSI scores. The OSI improvement of 0~11 year-old group was significantly higher than the other groups after 12 month treatment. 6. The OSI score of 97.75% was decreased after 12 month treatment compared to initial visit. 7. After 12 month treatment, the distribution of severe atopic dermatitis was decreased from 100% to 37.08%. 8. There was no significant difference betweent steroid group and non-steroid group on OSI scores at initial visit and after 12 month treatment. Conclusions : The OSI Score of severe atopic dermatitis patients was decreased on the significant rate with Korean medicine treatment for 12 months.

If we are using SNMP based network management systems and we need to manage new OSI based network elements, we have to develop new network management system. Most of the networks, which are composed of diverse. heterogeneous network nodes, are managed by CMIP based management system. The development of new management system, however, is very costly. In this paper, we show the design and implementation of the SNMP based network management system with minor changes for the management of OSI network and network elements.

Objective : The purpose of this study is to report the effectiveness of a long-term Korean Medicine Treatment on 1035 atopic dermatitis patients Methods : Objective SCORAD Index(OSI) is used for measuring the degree of atopic dermatitis with photos of total 1035 atopic dermatitis patients who has visited oriental clinic from January 9, 2011 to October 31, 2013. Then, OSI was estimated according to gender, age, period of treatment and intensity. Results : 1. The ratio of male to female was 44.4 : 55.6. All patients were constituted with 26.5% of 0~11 year-old group, 15.7% of 12~18 year-old and 57.9% of 19 and more year-old. 2. The ratio of OSI improvement was significantly higher in women than in men after 3 month treatment, but there was no significant difference after 6, 9 and 12 months. 3. The OSI improvement of 0~11 year-old group was significantly higher than the other groups after 3 month treatment. But at the other periods of treatment, there was no significantly difference of the improvement among 3 different groups of age. 4. After 3, 6, 9 and 12 month treatment, the score of OSI was significantly lower than before treatment. After 12 month treatment, the score of OSI was lowest compared to the other periods of treatment. 5. The final OSI score of 87.7% patients was decreased compared to the initial. 6. All patients had been divided with 1.93% of the mild, 22.7% of the moderate and 75.4% of the severe by OSI intensity at initial visit. At final visit, the composition of patients was changed to 14.6% of the mild, 53.7% of the moderate and 31.7% of the severe. 7. The mild patients had got 42.56% of OSI improvement at the final. And the moderate had got 37.72% of OSI improvement at the final. 8. The severe patients had got 36.76% of OSI improvement at the final. And 89.2% of the severe had got decreased final OSI score compared to the initial. Conclusion : There was a definite decreasing of OSI score on the significant rate of Atopic dermatitis patients who had been treated by Korean medicine treatment at least for 3 months.

인터넷의 급속한 성장으로 현재 통신 네트워크에서는 통신 프로토콜로서 TCP/IP 프로토콜을 주로 사용하고 있다. 그러나 이와는 달리 국내의 TMN(Telecommunication Management Network) 등에서는 ISO(International Organization for Standardization)에서 제안한 OSI(Open System Interconnection) 프로토콜을 통신 프로토콜로서 여전히 사용하고 있다. 대표적 통신 프로토콜인 TCP/IP와 OSI 프로토콜은 특성, 구조 및 제공하는 기능에서 서로 많은 차이점을 가지고 있어 두 프로토콜간의 연동은 쉽지 않다. 본 연구를 통하여 얻고자 하는 목표는 IP 네트워크클 통하여 연결된 OSI 프로토콜 시스템들간의 상호 연동이나. 본 논문에서는 IP 네트워크를 통한 OSI 프로토펄 시스템간의 상호 연동 방안으로, 멀티캐스트 통신을 간편하고 효율적으로 수행하는 CBT(Core Based Trees) 멀티캐스트 라우팅을 이용한 새로운 네트워크 터널 방안을 제안하고자 한다.

본고에서는 컴퓨터간의 통신을 가능케하는 통신 프로토콜에 대한 설명과 closed system의 단점, 그리고 이러한 문제점들을 해결하기 위해서 연구된 OSI의 개념을 설명하고 그 예를 간단히 소개하였다. OSI는 모든 컴퓨터를 자동적으로 연결해주는 요술과 같은 존재로 생각할 수도 있으나 그 나름대로 문제점을 갖고 있는 것 또한 현실이다.

Objectives: The purpose of this study is to examine whether there is a significant efficacy difference on infant and young child atopic dermatitis patients treated with Korean Medicine Treatment through 6 months between topical steroid used group and non-steroid group. Methods: The degree of atopic dermatitis was measured by the Objective SCORAD Index (OSI) with photographs of patients. Detailed analysis of the OSI score was compared based on the use of topical steroid. Results: 1. There was not a significant difference between the topical steroid group and the non-steroid group in regards of gender, age and initial OSI score. 2. The non-steroid group's OSI score decreased significantly from 50.17 to 29.20. 3. The topical steroid group's OSI score decreased significantly from 54.21 to 34.95. 76.19% of the patients in the topical steroid group discontinued steroid use within the 6-month period. The average time of discontinuation since the beginning of treatment was 3.36 months. 4. The OSI Improvement rate comparison of topical steroid group with non-steroid group did not show a significant difference over a 3-month and 6-month period. 5. Distribution of severe cases decreased in Both topical steroid and non-steroid group after 6 month treatment. Conclusions: The OSI score of infant and young child atopic dermatitis patients in both topical steroid and non-steroid group was decreased significantly with Korean medicine treatment through 6 months. There was no significant difference between topical steroid group and non-steroid group in OSI improvements over a 3-month period and 6-month period.

The CORBA provides a object-oriented middleware that lets applications extend their range across networks, languages, component boundaries, and operating systems. Java can provide a potable object that works in any operating system. Mapping Java into CORBA helps large scale information system operate through the Web by using the mobile code property of Java and object component technique of CORBA. This development environment is called the Object Web. This paper proposes an architecture of OSI network management with a CORBA manager using Object Web and an CORBA/CMIS gateway which apply a CMIS-level gateway model to gateway. In this architecture, CORBA manager is based on Object Web and can manage MOs in the OSI domain. The gateway has a role to translate CORBA IDLs into CMIS services and vice versa. In addition, an OSI agent is abstracted into a CORBA agent.
