In this paper, a foldable robot arm is designed for a drone manipulator. The foldable robot arm for a drone (FRAD) aims to clean solar panels. S-shape linkages are connected to form a foldable arm with a scissored structure. In order to increase the stiffness of the foldable arm, triangular prism (TP) structure arm by combining three scissored foldable arms was designed and developed with 3D printer technology. Three different scissored structures such as X-FRAD, S-FRAD, and TP-FRAD were developed for the stiffness test against the gravitational force. Experimental studies of solar panel cleaning tasks were conducted with a comparative performance analysis. .

The purposes of this study are to analyze and compare current state of subject directories of the health field in eight internet bookstores in domestic and abroad. A comparative analysis was carried out for KDC and DDC, using names of subdivisions within the health field of internet bookstore. Also, user interviews to find their information needs about the health field in internet bookstore were conducted. And then, based upon the findings, this study proposed a design principle and a new classification for the health field of internet bookstores. With evaluations of the experts from the field, a final classification schedule (1 class, 11 division, 60 subdivision, and 16 section) was suggested. The results of this study can be used for a foundation of classifying health resources efficiently in internet bookstores and other web sites. 본 연구는 인터넷 서점의 건강분야 분류체계의 개선방안으로 이를 위해 국내․외 8곳의 인터넷 서점의 건강분야 분류체계 현황을 비교분석하고, KDC, DDC의 해당 주제 분류항목과 비교 분석하였다. 그리고 인터넷 서점의 건강분야 분류체계의 이용에 대한 이용자 면담을 진행하였다. 그 결과를 바탕으로 설계원칙을 수립하고, 인터넷 서점의 건강분야 분류체계 설계안을 개발한 후, 실무자와 전문가 평가를 받아서 건강이란 대분류 아래 11개의 중분류 항목과 60개의 소분류 항목, 16개의 세분류 항목으로 제시하였다. 본 연구의 결과는 인터넷 서점은 물론 웹상에서 건강 관련 정보를 효율적으로 분류하는 기반이 될 것이다.

The purpose of the study was to report efficacy and complications in women aged more than 70 years underwent colpoclesis operation. In this study, we analyzed the efficacy and compliacations of colpoclesis in 57 consecutive women who underwent colpoclesis in ilsan paik hospital, inje university between March 2002 and February 2012. The 42 patients underwent partial colpoclesis and 15 patients underwent total colpoclesis.The mean operating time was 105.3±15.7 minutes in partial and 123.4±23.6 minutes in total colpoclesis. The mean blood loss was 230.5±30.5 in partial and 280.0±20.0ml in total colpocleisis. Intraoperative complication was not occurred. The postoperative complication was occurred in 3 patients (5.3%). 2 patients complaint about voiding difficulty, one had obstructive bowel symptom. No recurrent pelvic organ prolapse was occurred. Colpoclesis technique in elderly women is an effective and very safe treatment of severe pelvic organ prolapsed.

Choriocarcinomatosis dedifferentiation from adenocarcinoma of the uterine cervix is a very rare neoplasm. The prognosis of this tumor is extremely poor, despite chemotherapy and surgery. In the present study, we report a 45-year-old woman with Choriocarcinomatosis dedifferentiation from adenocarcinoma of the uterine cervix.

대학도서관 발전계획은 외부적으로는 도서관의 역할과 발전 방향에 대한 명시적인 선언이자 내부적으로는 도서관 서비스 제공을 위한 지침으로 기능한다는 점에서 중요한 의미를 지닌다. 발전계획 수립을 위해서는 국제적, 국가적 환경에 대한 이해, 개별 대학과 대학구성원에 대한 이해가 요구된다. 본 연구는 대학도서관과 관련된 국제 환경의 추세를 파악하기 위하여 해외 대학도서관 발전계획 사례를 조사하고, 내용분석과 네트워크 분석을 통해 그 동향을 파악하였다. 그 결과, 대부분의 해외 대학도서관에서는 ‘협업’, ‘컬렉션 개발 및 구축’, ‘연구지원’이라는 키워드를 주축으로 다양한 전략과 세부 계획을 제시하고 있는 것으로 나타났다. 이에 본 연구에서는 향후 대학도서관 발전계획 수립 시 고려해야 하는 사항으로, 발전계획 내 대학도서관의 사명과 비전, 가치의 구체적 명시, 문화적 다양성성과 형평성, 포용성 등의 핵심가치의 중요성 인식, 대학도서관 내외부의 파트너십 및 협업의 중요성 인식, 경영 목적 달성의 도구로서 대학도서관 발전계획의 활용을 제시하였다. The academic library development plan has external importance as it explicitly declares the library’s role and development direction. Internally, it is also a library service guideline. To develop the development plan, libraries must understand the trends and needs of international, national, and affiliating universities and their constituents. Accordingly, this research includes case, content, and network analyses of foreign academic libraries’ development plans to identify the trends. The analysis results show most foreign academic libraries employed various strategies and plans, which can be characterized as ‘collaboration,’ ‘collection development,’ and ‘research support.’ Consequently, we propose the following factors to consider when developing an academic library development plan: specification of mission, vision, and core values; recognition of core values such as diversity, equity, and inclusion; awareness of the significance of collaboration and partnership with other units within the universities and external organizations; and utilization of university library development plans as tools for achieving management objectives.

Usage of probiotic lactic acid bacteria (LAB) has recently attracted more attention due to increased interests in human health. They are also known to possess immunomodulatory effects by promoting cytokine secretion and thus modulate inflammatory responses. This study has aimed to evaluate the immunomodulatory effects and antimicrobial activities of 7 Lactobacillus strains that had been obtained from Korean Collection for Type Culture. The RAW 264.7 cell line was used as a macrophage model to investigate into assess the nonspecific effects of seven Lactobacillus strains on the production of NO as well as the cytokines TNF-α and IL-1β. The minimum inhibitory concentrations of several antibiotics for the Lactobacillus strains and the anti-bacterial activities of viable and sonicated cells, from three select Lactobacillus spp., were measured on the growth of pathogenic bacteria. The sonicated LAB also stimulated IL-1β and TNF-α production compared with the RAW cell only. In addition, sonicated L. rhamnosus and L. helvetilus were found to have higher anti-bacterial activity than the viable LAB in this study. These results suggest that sonicated LAB could be used to modulate immune responses with straindependent.

. This paper presents experimental studies of a solar panel cleaning task using a drone manipulator. The drone arm is designed to be foldable and lightweight for easy transport by the drone. A flexure mechanism was used to suppress vibration in a cleaning device attached to the end-effector of the drone arm. The foldable robot arm of the drone was implemented and uses hybrid force control to regulate contact force on a solar panel for the efficient cleaning task. Clustering algorithms were used to classify the groups to be cleaned for the efficient cleaning. Experimental studies of the cleaning solar panel with the foldable arm with a flexure system were conducted.
