  • Present study analyzes the rooftop gardening status, floristic composition and cost and return of the rooftop garden in Sylhet City Corporation of northeastern Bangladesh. Data was collected from 450 rooftop gardeners randomly during July-September 2010. Study reveal that rooftop gardening is generally for mental satisfaction (95.3%) followed by leisure time activity (87.8%) in the study area and almost all the family members of gardeners' were involved; while collection of planting materials, sites preparation and marketing of products were reported to be carried out by males only (male 71.33%). Middle income classes were most interested in rooftop gardening (43.78%). The survey recorded 53 plant species (35 families) of which Cucurbitaceae family represented highest eight species. Shrubs (28%) were highest followed by herbs (26%) among agri-crops (36%) and flower species (30%). About 89% of the rooftop gardeners procured planting materials from nursery, market, fair, neighbor, relative and friends and they mostly prefer to use seedlings (48%) for roof gardening followed by direct seed sowing (21%). Gardeners sell products sporadically in different local markets, directly or through intermediaries, with no uniform pricing for system. Rooftop gardening improves the food security and meet nutritional deficiency to the gardeners. Survey revealed that generally very few people consider rooftop gardening commercially to get profit and from the cost-return analysis this gardening system can be economically viable if proper and scientifically managed. The study conclude that active government and NGOs could play vital role to increasing this activities by providing training and motivate people with technical aspects of rooftop gardening.

  • The purpose of this study was to develop a continuing nursing care program for cancer patients and the caregivers staying at their home and to test its effects on patients' symptom distress, caregiver burden, and satisfaction of life. The continuing nursing care program was based on the homecare needs of cancer patients, and was provided by three clinical nurses who took care of the patients while they were hospitalized. The program consisted of discharge education about selfcare using education materials(book and handout) and provisions of direct care. These were counselling and education during which visiting patients' home one week after discharge and telephone counseling two weeks after discharge. Counseling by telephone was always available during the research period. A quasi-experimental research design was used to test the effects of the program. Subjects for this study were 53 cancer patients discharged from the hospital and caregivers. These subjects were assigned to an experimental group (n=23) receiving continuous nursing care, or to a control group (n=30) not receiving continuous nursing care. Data from control group was collected first to protect from contamination. Data collection was done from October of 1998 to February of 2000. The collected data was analysed using mean, t-test, and chi-square test computed by SPSS software. The summary of results was as follows: 1) The symptom distress was a little decreased at posttest, but there were no significant differences between the experimental and the control group in symptom distress. 2) The score of caregiver burden was significantly decreased in experimental group at posttest, but no differences in control group. 3) There were no significant differences between the experimental and control group in the satisfaction of life. 4) The score of satisfaction of continuing nursing care program in experimental group at posttest was 2.321 of 3. In conclusion, even though this study did not obtain evidence of effectiveness of continuing nursing care program on patients, such as. It is still expected to be effective by a more improved program. Therefore we want to give some suggestions for further studies. 1) It is needed to make a communication channel with the patient's doctor to response promptly and appropriately to patient's conditions. 2) The research is necessary on patients in terminal stage or early stage of cancer diagnosis who have many nursing needs. 3) It is needed to readjust the roles and job assignment of clinical nurse to implement effectively as a program provider.

  • This study examined the role of interpretation with various practices in art museums to seek a new meaning and a concept of art museum today. The exploration of interpretation would he a starting point to discuss about on art museums with professionals in each art-related field. While museums recognize the concept of interpretation and the scope of the functions in different levels, the study focused on the practices of collecting and exhibiting that will entrust the museum new realms of activities toward the audience. In particular, its emphases are set force on the information on the collections via the museum's web sites, interpretation policies, and theories and methodologies in exhibition development. Art museum websites well reflect how museums utilize the new medium to enhance the understanding of art works by providing in-depth art historical information, comprehensive contexts, and subject/concept based search methods. In recent decades, these have enacted changes to expand dimensions of interpretive functions in most museums, particularly in the United States and others. In an administrative perspective, Tate Gallery Interpretation Policy became an good example how an art museum put its interpretation philosophy as the basis of interpreting collection and public programs. Tate established functions of intrepretation and education not only within a task-based team but also as an intrer-divisional coorperation to provide an interpretation scheme of information provisions such as guide brochure, audio tour, multimedia content, and library. New environment and trends of museum exhibition, and its development processes stem from communication theories, object interpretation philosophy, display strategies, and various evaluation techniques through audiences, with the communication theories of Shannon and Weaver, Berlo's SMCR(Source-Message-Channel-Receiver) models were perceived as to understand the mechanism to communicate museum exhibits to visitors Suzan vogel's insight into object display strategy helped to conceive the mechanism of object recontextualization. She emphasized that the museum's practice to construe opinions and impressions through object display should be discreet and critical, therefore, the professionals to plan the exhibition should reveal the intention and their practices. For a prevailing new methodology from the field, the interpretive exhibition development processes are articulated as the front-end, formative, and summative evaluation, futhermore the team process in industrial product management models was adapted. These have turned out to be more interactive with visitors and effective to communicate the exhibition concepts and messages, hence resulting in enriched museum experiences. Finally the study concluded that understanding the aspects of interpretation should help art museums to set a framework for current practices to expand its public dimension. It can provide curators with a critical view to website planning and its content. And obviously, the interpretive exhibition development methodology will lead museum exhibition developers to be skilled in its current approaches to thematic exhibition concerning diverse subjects and topics.

  • 본 논문에서는 마이크로셀이나 피코셀과 같은 아주 작은 규모의 셀 영역 범위를 사용하는 차세대 무선 ATM 환경에서 효과적으로 이용될 수 있는 호제어절차 방식을 제시하고 개방형 큐잉 네트워크를 사용해 이의 성능분석을 행한다. 셀집단화 방식이라고 불리는 이 호제어절차는 단말의 이동성을 고려하여 새로운 호가 망 내로 수락될 때 단말이 이동할 확률이 높은 이웃한 물리적인 마이크로셀이나 피코셀들을 집합으로 모아서 지역적으로 매크로셀 정도로 넓은 영역을 담당하는 가상셀을 만들어 주는 방식으로, 높은 주파수 재사용 효율을 보장받으면서도 핸드오버에 따른 호제어절차의 개입을 줄일 수 있다는 장점을 지니고 있다. 그러나 셀집단화 방식에서는 일단 새로운 호가 가상셀 내의 영역으로 수락되고나면 제약없이 기지국 사이를 핸드오버하여 셀집단 내의 한 기지국에 집중하여 과부화 현상을 초래한다는 문제점이 있다. 따라서 본 논문에서는 셀집단화 방식이 사용하는 호수락제어의 판별기준으로서 기지국의 과부하 확률과 기지국이 과부하 상태에 머무르는 평균시간을 정의하고, 셀 집단 내에 존재할 수 있는 전체 통화호의 수를 일정한 값 이하로 제한할 경우와 그렇지 않을 경우를 비교하여 성능분석을 행하고 수치 결과를 보임으로써 셀집단화 방식의 효율성을 살펴본다.

  • Cyberspace permits us to more beyond traditional face-to-face, mail and telephone surveys, yet still to examine basic issues regarding the quality of data collection: sampling, questionnaire design, survey distribution, means of response, and database creation. This article address each of these issues by contrasting and comparing traditional survey methods(Paper-and-Pencil) with Internet or Personal Computer networks-mediated (Screen-and-Keyboard) survey methods also introduces researchers to this revolutionary and innovative tool and outlines a variety of practical methods for using the Internet or Personal Computer Networks. The revolution in telecommunications technology has fostered the rapid growth of the Internet all over the world. The Internet is a massive global network and comprising many national and international networks of interconnected computers. The Internet or Personal Computer Networks could be the comprehensive interactive tool that will facilitate the development of the skills. The Internet or Personal Computer Networks provides a virtual frontier to expand our access to information and to increase our knowledge and understanding of public opinion, political behavior, social trends and lifestyles through survey research. Comparable to other technological advancements, the Internet or Personal Computer Networks presents opportunities that will impact significantly on the process and quality of survey research now and in the twenty-first century. There are trade-offs between traditional and the Internet or Personal Computer Networks survey. The Internet or Personal Computer Networks is an important channel for obtaining information for target participants. The cost savings in time, efforts, and material were substantial. The use of the Internet or Personal Computer Networks survey tool will increase the quality of research environment. There are several limitations to the Internet or Personal Computer Network survey approach. It requires the researcher to be familiar with Internet navigation and E-mail, it is essential for this process. The use of Listserv and Newsgroup result in a biased sample of the population of corporate trainers. However, it is this group that participates in technology and is in the fore front of shaping the new organizations of interest, and therefore it consists of appropriate participants. If this survey method becomes popular and is too frequently used, potential respondents may become as annoyed with E-mail as the sometimes are with mail survey and junk mail. Being a member of the Listserv of Newsgroup may moderate that reaction. There is a need to determine efficient, effective ways for the researcher to strip identifiers from E-mail, so that respondents remain anonymous, while simultaneously blocking a respondent from responding to a particular survey instrument more than once. The optimum process would be on that is initiated by the researcher : simple, fast and inexpensive to administer and has credibility with respondents. This would protect the legitimacy of the sample and anonymity. Creating attractive Internet or Personal Computer Networks survey formats that build on the strengths of standardized structures but also capitalize on the dynamic and interactive capability of the medium. Without such innovations in survey design, it is difficult to imagine why potential survey respondents would use their time to answer questions. More must be done to create diverse and exciting ways of building an credibility between respondents and researchers on the Internet or Personal Computer Networks. We believe that the future of much exciting research is based in the Electronic survey research. The ability to communicate across distance, time, and national boundaries offers great possibilities for studying the ways in which technology and technological discourse are shaped. used, and disseminated ; the many recent doctoral dissertations that treat some aspect of electronic survey research testify to the increase focus on the Internet or Personal Computer Networks. Thus, scholars should begin a serious conversation about the methodological issues of conducting research In cyberspace. Of all the disciplines, Internet or Personal Computer Networks, emphasis on the relationship between technology and human communication, should take the lead in considering research in the cyberspace.
