Purpose: The purpose of this study was to investigate in-depth and to understand the experience of people living with HIV who work as caregivers for patients with AIDS. Methods: Data were collected from December 2010 to April 2011 through focus group and in-depth interviews. Ten people with HIV who work as caregivers for patients with AIDS participated in the research. Data were analyzed using Colaizzi`s method (1978). Results: The results showed the important themes to be ``feelings of sympathy``, ``burden of caregiving``. ``identifying one`s own self-worth` and ``hoping for a meaningful future``. People with HIV experienced deep empathy with patients with AIDS, and, even though they suffered physical and emotional distress from the caregiving process, they felt a sense of self-worth and found their existence connected with the world. Furthermore, they were taking more active care of themselves and hoping for a meaningful future. Conclusion: For successful social adaptation of people with HIV currently in job-seeking activities, various vocational rehabilitation services are necessary. The results of this study could be used in developing effective social support services for people living with HIV attempting workforcere-entry.

Nickel-titanium (NiTi) alloy thin films are attractive for micro-scale applications because of its fast response on temperature by high surface area, large work output, and higher strain recovery. In terms of superelasticity, Ni-rich NiTi alloys is primarily used due to enhanced phase transformation stability. As it is well known that the mechanical behavior of materials is scale dependent, it is crucial to understand size-effect on the mechanical behavior of NiTi for reliable operation in micro-scale devices. Therefore, in this study, mechanical behavior of Ni-rich NiTi thin films was characterized to identify the effect of the Ni concentration on superelasticity. Free-standing Ni-rich NiTi thin films were fabricated by sputter deposition followed by micro-electro-mechanicalsystem (MEMS) process. Tensile tests were conducted using a custom-built micro tensile tester. Films with higher Ni concentration showed improved strength with enhanced phase transformation stability.

본 연구의 목적은 도서관의 경쟁력 강화와 효율성 제고를 위해 공공도서관에 대한 전략경쟁분석을 통하여 차별화 전략방안을 도출하는 것이다. 이를 위하여 본 연구에서는 인천 중구에 위치한 4개의 공공도서관을 대상으로 현황분석, 경영자원 분석, 외부 및 내부 환경 분석 등을 실시하여 전략경쟁 상황을 파악하고, 도서관 관련 각종 통계자료, 전국도서관 운영평가자료, 도서관 이용자 만족도 조사결과, 도서관 최고경영자 및 선임사서들과의 면담을 통하여 4개 공공도서관의 경쟁사 분석, 고객세분화 분석, 고객가치 분석을 실시하였다. 본 연구의 결과, 도서관별 차별화 전략방안을 제시하면 다음과 같다. 첫째, 4개의 공공도서관은 지역 내에서 서로 다른 타깃 이용자층을 대상으로 하는 맞춤형 서비스의 제공이 필요하다. 둘째, 공공도서관은 지리적 접근성 및 지역의 인구 구성 등을 고려하여 정보취약계층을 비롯한 소극적 이용자를 대상으로 직접 찾아가는 능동적인 도서관 서비스의 개발이 필요하다. 셋째, 공공도서관은 지역의 정체성을 반영한 다양한 프로그램의 개발 및 지역사회와 협업하는 문화공동체를 형성하여야 한다. The purpose of this study is to derive differentiation strategy through strategy competition analysis on public libraries in order to enhance the competitiveness and efficiency of libraries. To that end, this study conducted a status analysis, management resources analysis, external and internal environment analysis on four public libraries located in Jung-gu, Incheon to identify the situation of strategy competition, and conducted a competitor analysis, customer segment analysis, and customer value analysis of four public libraries through various library related statistical data, national library operation evaluation data, library user satisfaction surveys, and interview with chief librarian and senior librarians. As the result, this study suggests three differentiation strategies by library. First of all, the four public libraries need to provide customized services targeting different target users within the region. Secondly, public libraries need to develop active library services that directly visit passive users, who are information have-nots, considering geographical accessibility and the composition of the population in the region. Last, public libraries should form a cultural community that cooperate with the local community and develop various programs that reflect the identity of the region.

황병순,김지영,장미,김기창,박영희,황인국,Hwang, Byung Soon,Kim, Ji Yeong,Jang, Mi,Kim, Gi-Chang,Park, Young-Hee,Hwang, In Guk 한국식품영양학회 2018 韓國食品營養學會誌 Vol.31 No.6

Deoduk (Codonopsis lanceolata) has a complex chemical composition that includes polyphenols, saponins, amino acids, and other unidentified compounds. The contents of tangshenoside and lobetyolin are considered as standard of quality evaluation of Deoduk. In this study, an ultra-performance liquid chromatography (UPLC) method was developed for the quantitative determination of the two marker constituents, tangshenoside and lobetyolin. The methods for determining the standards of quality were validated by measuring their linearity, specificity, limit of detection (LOD), limit of quantification (LOQ), precision, and accuracy using UPLC. Reversed-phase UPLC analysis was conducted quantitatively to identify individual tangshenoside and lobetyolin in Deoduk extracted with 50% (v/v) aqueous ethanol. We used 21 samples to carry out quantitative analysis of tangshenoside and lobetyolin. Based on their dry weights, the levels of tangshenoside and lobetyolin were 0.36~3.54 mg/g, 0.24~1.29 mg/g, respectively. These results will be valuable as basic data for standardization of Korean Deoduk.

Single and 28-day repeated dose toxicity studies of botulimnn toxin type A were carried out in ICR mice and Sprague-Dawley rats, respectively. In the single dose toxicity study, botulinwn toxin was injected intraperitoneally to male and female mice at a single dose of 40, 59, 89 133 and 200 ng/10 ml saline/kg. All animals died from 59 ng/kg group. Some clinical signs, such as decrease in locomotor activity, dyspnea, prone position and ptosis, were observed in most of both sexes from 59 ng/kg group, but no signs were seen in all animals at 40 ng/kg group. The results showed that the median lethal dose of botulinum toxin might be in the range of 40-59 ng/kg in both sexes. In the repeated dose toxicity study, the test material was administered intradermally for 28 days at doses of 0 (vehicle-treated control), 1.25, 2.5, 5.0 and $10.0ng/head/50{\mu}{\ell}$ saline in male and female rats. No test material-related changes were noted in survivals, clinical signs, food and water consumptions and gross finding in any group. Botulinum toxin treatment significantly decreased the body weight gain rate in male of 5.0 ng/head group and over and in female of 10.0 ng/head group compared to vehicle-treated control. One or more relative organ weights (i.e., spleen, thymus, liver and kidney) were increased significantly from 5.0 ng/head group compared to vehicle-treated control in both sexes. Serum biochemistry revealed increases in aspartate aminotransferase (AST), alanine aminotransferase (ALT), creatine phosphokinase, total protein and albumin in male, and increases in AST and ALT and decreases in $K^+$ and $Cl^-$ in female without dose-pendent manners. In the histopathological study, physical stimulation by needle caused slight inflammations of dennis. In addition, botulinum toxin treatment induced denervation of nerve cell and disuse of muscle, resulting in atrophy of skeletal muscle in both sexes from 2.5 ng/head group. When the antibodies to toxin were determined in all animals, a significant increase in serum antibodies was observed from 5.0 ng/head group. The results showed that the NOAEL of botulinum toxin might be 1.25 ng/head for 28-day repeated dose toxicity in rats.

본 연구는 섬모시풀 70% 에탄올 추출물과 분획물에 대한 천연 화장품 소재의 가능성에 대해 조사하였다. 섬모시풀을 70% 에탄올 추출물과 헥산, 디클로로메탄, 에틸아세테이트, 부탄올 등의 순차적으로 용매별 분획을 제작하였다. DPPH과 ABTS 시험결과, 에틸아세테이트 분획물은 우수한 라디칼 소거 활성을 보였다. 항균활성은 Staphylococcus aureus, Staphylococcus epidermidis, Cutibacterium acnes와 항생제내성균주에 대해서 paper disc 방법, 최소저해농도 및 생육억제율을 조사하였다. 그 결과, S. aureus, S. epidermidis, C. acnes 균주에 디클로로메탄과 에틸아세테이트 분획물에서 추출물과 다른 분획물에 비해 우수한 항균력을 확인하였다. 또한, 에틸아세테이트 분획물은 lipopolysaccharide (LPS) 처리한 RAW 264.7 Cell에서 NO 생성억제 활성을 확인하였다. 이로써 섬모시풀 추출물과 분획물은 세포독성이 없으며, 항산화, 항균 및 항염 효과를 보였다. 이 결과는 섬모시풀 추출물과 분획물이 항산화 활성을 가지는 효과적인 화장품 소재로 적용 가능하다는 것을 시사한다. The purpose of this study was to investigate the possible use of the Boehmeria nivea var. nipononivea extract and fractions for the development of natural cosmetic ingredients. The leaves of B. nivea var. nipononivea, extracted by 70% ethanol, were sequentially fractionated with n-hexane, dichloromethane, ethylacetate, and n-butanol. As a result of DPPH and ABTS test, ethyl acetate fractionation was shown to be excellent in radical scavenging activity. For the antimicrobial activities against Staphylococcus aureus, Staphylococcus epidermidis, Cutibacterium acnes and antibiotic resistant strains, MIC and birth control rate were observed by paper disc method. In the antibacterial activity by the disc diffusion assay against S. aureus, S. epidermidis and C. acnes, the dichloromethane and ethylacetate fraction showed stronger antibacterial activity than the other fractions and extract. Moreover, the ethylacetate fraction showed strong nitric oxide (NO) production inhibitory effect in lipopolysaccharide (LPS)-stimulated RAW 264.7 cell. In conclusion, we found that B. nivea var. nipononivea extract was not cytotoxic and showed antioxidant, antimicrobial and anti-inflammatory effects. These results suggest that the Boehmeria nivea var. nipononivea extract and fractions could be applied as an effective cosmetic material with antioxidant activity.
