Introduction : In this study, we applied the immediate loading to implant using temporary prosthesis, and compared the treatment results by each placement site, amongst pre-loading period. The study was intended to search for occurrence of complications and the amount of marginal bone resorption. Materials and Methods : We retrospectively reviewed the medical records of 99 cases of implants from 29 patients who were treated at Seoul National University Bundang Hospital from September 2003 to September 2008. We grouped all the cases by placement arches and pre-loading periods, and subdivided each group by placement site(anterior/posterior), type of prosthesis(full-mouth cross splinting/Partial multiple splinting, Single) Results : In the cases of anterior maxilla, the average amounts of marginal bone resorption showed 1.710.71 ±mm in group 1, and 1.44±0.69mm in group 2, which means they revealed no statistically significant difference between group 1 and group 2(p=0.646). In the cases of posterior maxilla, the average amounts of marginal bone resorption showed 1.25 ± 0.72mm in group 1, and 1.14±1.15mm in group 2, which means they were not statistically significant. In the cases of anterior mandible, there was no cases classified as group 4, but the average amounts of marginal bone resorption in group 3 showed 1.38±pm 0.79mm. In the cases of posterior mandible, Group 3 showed 1.39 ±0.64mm, and group 4 showed 1.84 ±1.19mm as amounts of marginal bone resorption, which means they revealed no statistically significant difference between group 3 and group 4(P=0.210). The survival rate of group1 was 97.14%, 92.1% of group3, and 100% of group 2 and group4. According to each type of prosthesis, each average amount of marginal bone resorption revealed no statistically significant difference in maxi11a(p=0.575) in mandible(p=0.206). Conclusion : It is concluded that the marginal bone resorption and the rate of complications might not be affected by placement sites and pre-loading periods. The marginal bone resorption and the rate of complications might vary as different bone quality of placement site and implant system, diameter, length, etc. It is suggested that the proper placement of immediate loading implants decreases the whole treatment period and any inconvenience occurred to patients.

The purpose of this study is to analyze the risk management competency of the OSC (Off-Site Construction) project execution organization in perspective of supply chain management focusing on its importance and performance. It analyzes the effort needed to strengthen management competency through surveys of construction experts and IPA (Importance-Performance Analysis). In the case of risk factors related to module quality, overall, it shows high importance. Therefore, competency building is required to increase the performance of management tasks to secure module quality. It is expected to contribute to strategically establishing an OSC customized management system by providing fundamental data for diagnosing OSC performing organizations’ capabilities and establishing improvement directions.

시중에 널리 사용되는 스마트홈 관련 제품들은 스마트홈 패드와 스마트홈 애플리케이션과 같이 전자기기로 스마트홈을 제어하는 제품들이 상용화 되어있다. 전자기기를 다루는 데 익숙하지 않거나 스마트폰을 사용하지 않는 사람들의 경우에는 이러한 기능들을 활용하기에는 어려움을 겪게 되고, 스마트홈 패드의 경우에는 거동이 불편한 사람들이 편리하게 이용하기에는 어려움이 많다. 본 논문에서는 이런 문제점을 해결하기 위해 집 안에서 와이파이 신호를 이용하여 웨어러블 스마트홈 시스템 컨트롤러의 구조와 구현 방법을 제안한다.

최근, 소프트웨어의 재사용성, 생산성, 그리고 품질을 높이기 위한 방법으로서 컴포넌트 기반의 소프트웨어 개발(CBD:Component-Based Development) 방식이 빠르게 확산되고 있다. CBD를 효과적으로 수행하기 위해서는 응용 컴포넌트들이 서로 정확하게 결합하여 작동할 수 있는 아키텍쳐를 기반으로 하여 컴포넌트의 생성과 합성 작업이 이루어질 수 있어야 한다. 소프트웨어 아키텍쳐는 아키텍쳐 기술 언어(ADL:Architecture Description Language)를 사용하여 기술되어야 정확하고 엄밀한 아키텍쳐 모델링이 가능하다. 본 논문에서는 도메인 아키텍쳐 기반의 CBD에 효과적으로 사용될 수 있는 ADL 지원도구의 시스템 아키텍쳐를 제안하고, 제안한 시스템 아키텍쳐의 각 구성 요소들에 대하여 기술한다. 그리고 C2 스타일의 아키텍쳐 기술을 지원하는 UCI(University of California in Irvine)의 C2SADL을 변경하여 재정의한 ADL과 지원도구로서 개발 중인 ADL 지원도구의 설계 및 구현 방법을 기술한다. 본 연구팀이 개발 중인 ADL 지원도구는 본 논문에서 제안한 ADL 지원도구의 시스템 아키텍쳐의 일부 구성 요소들을 구현한다. Recently, component-based development (CBD) is rapidly spreading as a way of improving the reusability, productivity, and quality of software. For CBD to be effective in achieving such design objectives, the creation and integration of components must be based on a well-defined architecture that guides the correct composition and cooperation of application components. Software architecture must be described using an architecture description language (ADL) to ensure the correctness and preciseness of architecture models. In this paper, we propose the system architecture of an ADL tool set that can effectively support the use of CBD based on the domain architecture and we describe each component of the proposed system architecture. We also modify and redefine C2SADL that was developed to support the use of the description of C2 architectural style by UCI (University of California in Irvine) to facilitate the integration of separately described architecture models, and introduce the method of design and implementation of our ADL processor that partially implements the proposed ADL system architecture.

Objectives : Kamibojungikgi-tang is one of the most frequently used medical treatment for the allergic rhinitis. The main symptoms of the allergic rhinitis are nasal obstruction, watery rhinorrhea, and sneezing. In this study, we investigated the medical effect of the Kamibojungikgi -tang with intradermal acupuncture treatment on the allergic rhinitis in 10-11 years old children. Methods : For 8 weeks, we administered Kamibojungikgi-tang to 84 patients and treated them with intradermal acupuncture. We checked their serum IgE and examined 10 symptoms of the allergic rhinitis (nasal obstruction, watery rhiorrhea, sneezing, nasal pruritus, hyposmia, quality of life, color of nasal mucosa, edema of nasal mucosa, postnasal drip, and complication). Results : 1. Serum IgE decreased 2.62 point. which showed no significance. 2. Nasal obstruction, watery rhiorrhea, sneezing, nasal pruritus, hyposmia, quality of life, color of nasal mucosa, edema of nasal mucosa, and postnasal drip were improved. (p<0.005) 3. Complication showed no significance. Conclusions : After treatment, we had a lower symptom index scores. Kamibojungikgi-tang with intradermal acupuncture treatment had an effect on the allergic rhinitis.
