Lignocellulosic biomass (e.g., poplar wood) provides a unique and sustainable resource for environmentally safe organic fuels and chemicals. The core of this study is the pretreatment step involved in bioconversion processes. Pretreatment is required to realize high yields vital to commercial success. The focus of the pretreatment step is to methodically change key features of the biomass to favor enzymatic hydrolysis. This work assesses the compositional changes due to oxidative and non-oxidative longterm lime pretreatment of poplar wood (up to 4 weeks of pretreatment) at mild temperatures (25ºC to 65ºC), and their effect on the enzymatic yield of glucan and xylan. The most important pretreatment yield of lignin was 54 g lignin remaining/100 g lignin in raw biomass, and was accomplished for 4-week lime pretreatment at 65ºC in oxidative conditions. The corresponding pretreatment yields of glucan and xylan were 85.9 g glucan recovered/100 g glucan in raw biomass and 80.2 g xylan recovered/100 g xylan in raw biomass respectively. For poplar wood oxidatively pretreated with lime for 4 weeks at 65ºC and enzymatically hydrolyzed with an enzyme loading of 15 FPU/g glucan in raw biomass during a 3-day period, the best overall yields of glucan and xylan, were 80.7 g glucan hydrolyzed/100 g glucan in raw biomass and 66.9 g xylan hydrolyzed/100 g xylan in raw biomass respectively. The corresponding hydrolysis yields were 94.0 g glucan hydrolyzed/100 g glucan in treated biomass and 83.5 g xylan hydrolyzed/100 g xylan in treated biomass respectively. Because there is a previous study of long-term lime pretreatment of corn stover (Kim, 2004), the data obtained in this work show the effect of using woody lignocellulose as substrate. From the comparison, resulted that in the case of poplar wood oxidatively pretreated at 65ºC for 4 weeks, less lignin was removed and more carbohydrates were solubilized, however the hydrolysis yield of glucan was almost equal and the hydrolysis yield of xylan was higher than the reported by Kim for corn stover oxidatively pretreated at 55ºC for 4 weeks. The overall yield of glucan resulted lower in the case of poplar wood because of the lower pretreatment yield of glucan. Thus, it is important to complete the mass balances including an analysis on the pretreatment liquor to determine if the solubilized glucan was degraded.

This study is to discuss the services of public ¡§Sheng Mu¡¨ Time Bank in Taiwan. Time Bank was developed as a way of providing non-medical services for older people ¡V helping them to stay in the own homes, keep hospital appointments and stay healthy. Unlike traditional services of volunteers, Time Bank enables volunteers to earn and pay time credits for giving and receiving non-medical services.That is to say, Time Bank is a community plan for mutual contribution. Everyone can give and everyone can get. ¡§Sheng Mu¡¨ Time Bank was established by Taiwan governmental instituation in 1998. Since ¡§Sheng Mu¡¨ Time Bank has over ten years of experience in promoting this program, there must be some difficults and problems during promoting process.Thus, the first purpose of this study is to understand what Time Bank is and how it works. Besides, this study is to understand how do managers of volunteers and volunteers think about Time Bank. Finally, this study is to find out the difficults and problems in promoting this program.

Under the well developed economy and the medical, aged population brings up the related medical service demands. In the future, the service quality is a key to determines the life of long-term-care institutes. The purpose of this study to address the relationships among the product factors by which people make a decision. Besides, the construction of what degrees of people emphasis on them is also explored as well. Based on the above, ten nights were used to collect 1097 effective samples by making phone calls. After analysis by statistics software, the conclusions are as below, 1. Men pay more attention to opinions of medical professionals than women. In the inspections of reference group, opinions of relatives & friends (46%) hardly differ from them of medical professionals (47%). However, It was found that man intends to refer more of medical professionals than women, and women put more emphasis on them relatives and friends than men in the cross analysis of gender-reference group. 2. The better educated people put more emphasis on quality of institutes. We can expect the better educated people earn more incomes, and they usually can accept the more expenses which are set as 25 thousands for each month. And this also highlights they concern the service quality than other groups even they¡¦re charged more. 3. It determines the service quality whether an institute has medical professionals or not. This highlights the expectations and trust of people to an institute with medical professionals. Under the trends of diseases changes of the older, the daily care of them is not only included, but also long term tracing or inspection on diseases is necessary. 4. In the past affections on filial piety of China, people thought that distances between the institute and home will be a key factor to choose for visit and take over the older easier. However, People do not care how far from home, when an institute with good service quality can also provide better prices. Key words: Kaohsiung Area, Long Term Care Institute

The purpose of this study was, first, to further our understanding of the experience of dying in a long-term care (LTC) facility from the perspective of family members and second, to identify the relationships between the various factors which may influence satisfaction with end-of-life care. Using a sequential mixed methods design, a convenience sample of 87 family members completed a survey interview using a modified version of the Toolkit of Instruments to Measure End-of-life Care (TIME) Nursing Home Version in the first phase of the study. Findings from the parametric and non-parametric analyses indicated that family satisfaction with end-of-life care was best predicted by contact and communication with nursing staff, feeling that care provided at the end of life met expectations, staff providing consistent care, feeling that the health care aide listened to their concerns about care and that respondents felt they had received enough emotional support. Being transferred to hospital in the last month of life, dying in a place other than the LTC facility, and respondent age and employment status were all associated with significant mean differences in satisfaction scores. In the second phase, three focus groups were conducted to further explore areas of satisfaction and dissatisfaction with end-of-life care. Focus groups provided confirmation of the findings of the first phase of the study and were instrumental in developing a list of ten recommendations for improvements in end-of-life care delivery. Recommendations for future research are made based on the study results.

Introduction: Vitamin D deficiency is prevalent among older adults in long-term care (LTC) contributing to increased risk of falls and fractures, and decreased quality of life. The primary factors include limited dietary sources containing vitamin D, poor dietary intake, and low sunlight exposure. Vitamin D supplementation is recommended in LTC; however this practice varies across Canada. Objectives: The objectives of this study were to 1) examine the perceptions of LTC health professionals, staff, and visitors (family and friends) regarding vitamin D supplementation in LTC facilities; and (2) determine what barriers exist in providing vitamin D supplementation to all residents in LTC facilities. Methods: The study was conducted in two phases. Phase 1: Five focus group sessions (9-12 health professionals per group) were conducted in 5 LTC facilities within a Manitoba Regional Health Authority. Each focus group session was audio recorded to assist in generating themes. Phase 2: A self-administered nutrition survey was completed by LTC staff, health professionals, and visitors (family and friends) in all five recruited LTC facilities. Descriptive statistical analyses were conducted. Results: Phase 1: A total of 51 individuals participated (mean age = 46.7 years ± 10.3; female = 90.2%). The majority of participants consisted of Registered Nurses, Health Care Aides, Clinical Dietitians, Pharmacists, Social Workers, Recreation Therapists, and Administrators. Phase 2: A total of 102 individuals participated with an average age of 48.4 ± 13.8 years and were predominately (87.3%) female. Eighty-five percent of participants were LTC health professionals and staff, and 14.7% were visitors (family or friend) of a LTC resident. The results from both phases found that perceptions were positive about providing vitamin D supplementation to residents. Eighty-two percent (phase 1) and 92.2% (phase 2) of participants thought that receiving a supplement would make a difference to the overall health of LTC residents. The major barriers to vitamin D supplementation were: cost (healthcare cost, cost of the supplement, and cost of laboratory tests for serum vitamin D levels), the complexity of residents due to swallowing problems and reluctance with taking medications, polypharmacy, physician resistance, and differences between participants’ knowledge and education on vitamin D. Conclusions: Providing vitamin D supplementation to LTC residents was deemed important and would improve their overall health, but more education is needed to prevent vitamin D deficiency in LTC.

This study investigates the growth and non-growth of small-and-medium-sized enterprises (SMEs) over the long-term. A multiple case study methodology was used to examine the growth paths of eight SMEs over a period of fourteen years. Four firms represented manufacturing and four, the professional and business services industry. The firms were paired according to similar sectors and contrasting growth paths. Longitudinal employment data illustrated the firms’ growth paths, and the primary method of data collection was semi-structured interviews of the firms’ owner-managers. The research incorporated extensive literature, including traditional research approaches and life cycle models and emergent literature on organisational learning and growth paths. The growth and non-growth firms were found to be distinct from each other, regardless of industry. The growth firms’ owner-managers had strong growth ambitions and actively sought the recognition and challenges that arise from the operation of multiple growth businesses. The non-growth owner-managers had passive growth ambitions and focused on maintaining their accustomed lifestyle. These differences were also illustrated in the firms’ approaches to networking, internationalisation and technological advancement. The growth firm owner-managers were all portfolio entrepreneurs and had strong professional networks, which they considered were strategically vital. In contrast, the non-growth owner-managers were novice entrepreneurs and were nonchalant towards networking. Innovation and flexibility were identified as important characteristics in the long-term performance of the firms. Findings also indicated that owner-managers’ perceptions of their external business environment determined the influence it had on the business. Individual and collective learning processes underpin these findings in determining long-term growth performance of the firms. The strong interrelationships between owner-managers, learning processes, and longitudinal growth paths suggest areas of future research.
