The Peri-implantitis causes inflammation of periodontal tissue and bone loss. It contaminates surface of implants. Therefore, guided bone regeneration has been used for the treatment of this disease. For the reosseointegration of the exposed surface, various mechanical and chemical methods have been used for cleaning and detoxication of implant surface. Among these methods, air-powder abrasive and oversaturated citrate are known to be most effective. However, these treatments may deform implant surface. In this research, changes of surface roughness they were examined. 10 experimental machined titanium cylinder models were fabricated to be used for control groups. Each of them was air powder abraded for 1 minute and they were named group 1. And then, group 1 were burnished with cotton pellets soaked with citrate for 30 seconds(Group 2), 1 minute(Group 3), 3 minutes(Group 4), and 5 minutes(Group 5) burnishing were applied for grouping respectively. Each group were examined with SPM, and their surface roughness were measured and analyzed. 1. Surface roughness of titanium decreased when it was air-powder abraded for 1 minute. It was statistically significant. 2. When Air-powder abraded titanium were treated with citrate for 3 minutes, Their surface roughness was the lowest. Titanium treated for 1 minute was the second lowest and 30 seconds was the third and titanium burnished for 5 minutes was the highest. 3. Surface roughness of titanium which was treated with citrate was decreased till 3 minutes, which was statistically significant. There was no statistical significance from 30 seconds to 1 minute and from 1 minute to 3 minutes, and there was statistical significance from 30 seconds to 3 minutes. 4. Oxide layer was formed when titanium is exposed to air, and it was removed when air-powder abraded. It was made when treated with citrate. It is thought that citrate treatment is necessary after the air-powder abrasion, and 1 minute is clinically and qualitatively adequate for burnishing time of citrate.

This study was conducted to compare and evaluate the difference in washing and disinfection when the Hazard Analysis and Critical Control Point (HACCP) protocol was applied to foodservice operations. The results of the survey were as follows: Among the 116 foodservice operations surveyed, 67.2% were HACCP-compliant and 32.8% were not HACCP-compliant. Also, 62.9% served meals once daily, and 79.3% conducted food safety education once a month. Compared to HACCP non-compliant foodservice operations, the disinfection performance of HACCP-compliant operations was significantly better concerning worktables (p<0.001), food inspection tables (p<0.001), preparation tables for distribution (p<0.01), serving tables (p<0.01), overflow and trenches(p<0.05), sinks (p<0.05), and insect attracting lamps (p<0.01). Similarly, the disinfection performance of HACCP-compliant foodservice operations was significantly better for 18 cooking utensils and personal tools such as food slicers (p<0.001), multiple cooking machines (p<0.05), tray carts (p<0.001), stainless steel tools (p<0.001), rubber gloves (p<0.05). Worktables (45.1%), serving tables (29.6%), sinks (37.0%), and scales (21.6%) were most often disinfected 'at the end of each task', while food inspection tables (36.5%), food preparation tables for distribution (31.2%), dish machines (34.2%), overflow and trenches (25.7%), and floors (25.8%) were most often disinfected 'once a day'. All cooking utensils were most often disinfected 'at the end of each task'. 'Chemical disinfection' was most frequently used in all foodservice facilities. To improve the food safety management of foodservice operations, it is necessary to apply the HACCP protocol and comply with the washing and disinfection manual.

Social Filtering 환경에서 사용자 관심사를 고려한 Annotation 디스플레이 설계 및 구현

웹 Annotation은 개인 노트의 수단이며, 동료들 사이에서 의견 교환과 협업할 수 있도록 도와준다[1]. 또한, Annotation들은 데이터베이스, 문서, 그리고 분산된 환경에서 중요한 일이나 사건을 기록하는데 바람직하다[2]. 이런 Annotation들은 통신수단의 발달과 함께 증가한 인터넷 사용자들의 활발한 의견교환을 통해 빠르게 증가하고 있다. 때문에 사용자들은 많은 Annotation들 중 적절한 Annotation을 선택하기가 쉽지 않다. 현재, 웹 상에서의 Annotation에 관련된 연구들이 활발히 진행 중에 있다. 그러나 한 문서 또는 한 Anchor에 존재하는 많은 Annotation들을 효과적으로 제공하는 방법에 관한 연구는 미비한 실정이다. 기존의 대부분의 Annotation System들은 다수의 Annotation들은 관련성이나, 사용자 특성을 고려하지 않고, 입력된 무의미한 순서로 제공하며 생성된 anchor와 Annotation들을 모두 보여준다. 이로 인해, 한 문서에 너무 많은 Annotation이 생성되어 문서의 레이아웃을 손상시킬 수 있으며[3], anchor와 문서의 이해 시간을 가중시킨다[4]. 따라서 본 논문에서는 웹 문서에 생성된 다수의 Anchor들과 Annotation들을 좀 더 효율적으로 제공하기 우해 협업 환경에서 효과적인 Social Filtering[5]을 적용하여 적절한 Anchor와 Annotation마을 제공하는 사용자 관심사에 의한 Annotation 처리 기법을 제안한다. 더불어 한 Anchor에 생성된 Annotation들에 순위를 부여하여 보다 적절한 Annotation을 먼저 접근할 수 있는 Anchor에 대한 Annotation내에서의 순위부여 기법을 제안한다.

본 연구목적은 국제결혼 이주여성의 자아존중감과 적응유연성 간 관계에서 심리적 행복감의 조절효과를 확인하는데 있다. 이를 위해 전라남도 지역 복지관과 다문화지원센터의 도움을 받아 총 148명을 대상으로 설문하였고, 이중 139부를 분석에 사용하였다. 연구결과 첫째, 국제결혼 이주여성의 자아존중감이 적응유연성에 유의한 영향을 미치는 것으로 조사되었다. 둘째, 자아존중감과 적응유연성 간 관계에서 심리적 행복감 즉, 세부적으로 생활만족도의 조절효과가 있는 것으로 나타났다. 본 연구결과에 기반하여 국제결혼 이주여성의 적응유연성 향상을 위해 실천적 제언을 하였다. The purpose of this study was to examine the relationship between the self-Esteem and resilience in married immigrant women, to explore the moderate effect of psychology happiness on those relationship and to suggest practical implications for social work services for those married immigrant women. Data for this study were collected through the use of a survey instrument completed by 139 samples from 148 samples. Collected data were analysed by moderated multiple regression. The findings of this study were as follows: First, this study provided clear evidence that the self-Esteem was very important variable which affected on resilience in married immigrant women. Second, the life satisfaction had moderate effect on relationship between self-Esteem and resilience. Based on these findings, Practice and policy implications as well as further research topics were discussed to aid the search for highly effective interventions.
