The growing interest in nanotechnology has resulted in increasing concern and a number of published environmental and workplace measurements for assessing occupational exposure to engineered nanomaterials. However, the amount of previous exposure data remains limited. Furthermore the data available was collected with extensive variation in terms of exposure measurement strategy, which limits the ability to pool the data in the future. In response, this paper reviewed several pertinent issues related to exposure measurement strategy to suggest a harmonized measurement strategy which would make exposure data more useful in the future, e.g. correlation between exposure metrics, relationship between activity and exposure, task-based or shift-based assessment, background concentration, limitation of personal exposure monitoring and other determinants of exposure/modeling. An improved sampling strategy for nanomaterial exposure assessment should be considered in order to maximize the use of the data from various real time monitoring instruments.

Purpose: The purpose of this study was to examine perceived needs for exercise programs among adults in the workforce based on sociodemographic characteristics and health-related behaviors. Methods: The sample consisted of 182 office workers, sales workers, and service workers recruited at a worksite in Seoul (97 males and 85 females, Mean age=34.6, SD=7.71). Study participants completed a structured questionnaire on health-related behaviors and areas of needs for exercise programs. Analysis of data was performed using descriptive statistics and chi-square tests. Results: Workers with greater interest in exercise reported to engage in exercise. Significant differences were observed in goals of exercise, preferred exercise, preferred methods for delivery of exercise, preferred exercise monitoring, and social support for exercise maintenance according to age, sex, marital status, education, commuting time, occupation, alcohol use, smoking, and current participation in exercise. There were no differences in areas of exercise program needs by consumption of high calorie foods. Conclusion: Public health nurses can use these findings for development and implementation of tailored exercise programs to promote health for workers whose physical activity is insufficient.

Photosynthetic bacteria (PSB) attract considerable interest as useful microorganisms; nevertheless, a generalized culture technique has not been previously reported owing to difficulty in their cultivation. Therefore, a simple culture technique suitable for public use was investigated. Among the PSB tested, the strain Rhodobacter azotoformans EBN-7 was the most suitable for scale-up production because it showed the highest specific growth rate (0.20 h^-1) on basal medium. In scale-up cultivation (500 L), R. azotoformans EBN-7 showed 4.50 × 10¹⁰ colony-forming units mL^-1 (number of viable cells), dry cell weight of 26.8 g/L, and a specific growth rate of 0.15 h^-1. Cultivation using this final culture broth (as seed culture) in a 15 L simple reactor was successful, with maintenance of cell activity evident. For use as seed culture, the maximum allowable preservation period of R. azotoformans EBN-7 at 4℃ was 3 months. When R. azotoformans EBN-7 cultivated in a simple technique was applied to shrimp aquaculture water, NH₄⁺-N was reduced from 0.61 mg/L to 0.24 mg/L (by 60.7%) in 4 days in comparison with the control. Thus, this simple culture technique using R. azotoformans EBN-7 has the potential for a good removal efficiency of NH₄⁺-N, making seed culture easier and suitable for public use.

Aloe vera has several beneficial health effects as it interacts with probiotics and is also a source of prebiotics, antioxidants, and other bioactive materials. Thus, there has been increasing interest in the development of beverages containing Aloe vera. In this investigation, sensory qualities were estimated by fortifying oil isolated from Aloe vera in non-dairy and dairy products at different concentrations (fortified with 1% increments from 0% to 5%). Because of the strong aroma and strong yellow color of aloe oil, the sensory quality values estimated in this study were generally low. However, the samples fortified with 1% aloe oil exhibited the best sensory quality values compared with the control. Consequently, the results of this study are valuable as preliminary findings to determine the various sensory qualities of kefir fortified with aloe oil. To improve sensory qualities in the future, it is necessary to estimate the optimal lowering of the concentration of fortified aloe oil, and assess whether aloe oil exhibits various biofunctional activities at different concentrations.

Individuals who are vulnerable during disaster - including elderly, people with disabilities, children, pregnant women and etc - have a strong desire to protect themselves when disaster strikes since they are less capable to deal with the impact of disaster. Their experience and effort to keep them safe can be used as a resource to reduce the impacts of disaster not only for them but also for the community as a whole. Therefore, voluntary disaster management program will contribute to our society as a tool to respond effectively to disaster not only to meet the vulnerable's special needs but also to enhance community safety and public interest. This paper suggests a model that able "disaster vulnerable population" to take a leadership role in identifying risk and vulnerability factors, recommending disaster management strategy, and through that, contributing to enhance society's disaster plan. Therefore, this study aimed to surveyed individuals including "disaster vulnerable population" in order to assess the vulnerable's participation in disaster related volunteer work and surveyed associated institutions(volunteer centers, community centers) in order to research currently existing relevant programmes and the participation of "disaster vulnerable population" in such programmes. Also conducted focus group interview to explore voluntary program which will possibly integrate "disaster vulnerable population" into disaster management activities. As a result, three types of voluntary disaster management programs - education, public-relations, and activity - were suggested.

본 연구는 최신 기술을 활용한 도서관의 특화 서비스인 내용적 북트레일러 서비스가 이용자의 독서 관련 행동반응에 미치는 효과를 파악하고자 하였다. 이를 위해 AIDMA&AISAS 모델을 사용하여 주목(Attention), 관심(Interest), 탐색(Search), 욕구(Desire), 기억(Memory), 행동(Action), 공유(Share)의 7가지 이용자 행동반응을 측정하였다. 인천광역시 소재 13개 공공도서관에서 북트레일러 서비스를 경험한 이용자에게 설문조사를 실시하여 총 287명의 응답을 분석하였다. 분석 결과, 내용적 유형인 메시지 활용형, 갈등 활용형, 인물 활용형 모두 이용자 행동반응에 유의미한 차이가 있었으며, 특히, 인물 활용형이 가장 높은 영향을, 다음으로 갈등 활용형, 메시지 활용형이 영향을 끼치는 것으로 나타났다. 그러나, 사후 검정 결과 관심과 탐색, 이용자만족도에서는 갈등 활용형과 인물 활용형 간에 유의미한 차이가 발생하지 않았다. 본 연구는 외형적 유형의 북트레일러 서비스의 효과를 측정한 선행 연구들과 비교할 때, 내용적 유형의 북트레일러를 통해 이용자 행동반응을 측정하고 유의미한 효과를 확인하였다는 점에서 학문적 의의가 있으며, 더 나아가 효과적인 북트레일러 서비스에 위한 실질적인 함의를 제공하였다.

Purpose: This study critically reviewed nursing research psychotropic drugs that has been published in Korean journals. Another aim of this study was to identify trends in nursing research on psychotropic drugs and make suggestions for further study in Korea. Methods: Data were collected from degree theses and original articles on psychotropic drugs published in Korean journals from 1992 to 2013. Thirty-four articles were analyzed of which at least one nursing author participated in the study. Search keywords were "psychotropic drug" and "mentally ill patient & medication". Results: For the research design, quasi-experimental study was 58.8%, descriptive study was 17.7%, descriptive correlational study was 8.8%, qualitative study was 8.8% and model development research was 5.9%. Variables measured were knowledge of medication & symptom management, knowledge of disease, side effects, drug attitude, medication pattern, diet & activity, quality of life, and self-care. Conclusion: Despite recent increased interest in psychiatric medication, research on psychotropic drugs remains very limited, particularly regarding findings from a nurse's perspective. More research project should be designed to develop programs for the treatment of side effects from a nursing view-point.
