Effect of Jellyfish fertilizer on Seedling Growth and Soil Properties (第43回大会特集)
The excessive increase of jellyfish swarms could threaten the fishers and the marine food chain. The aim of research was to evaluate the potential benefit of the jellyfish as a fertilizer for different trees. The greenhouse experiment was conducted at Kutan, Chuncheon, South Korea using two tree species. Jellyfish was applied to soil before planting at different application rates (1.6, 2.7, 5.5, and 11.1 g/kg). Generally, the addition of jellyfish fertilizer increased soil moisture contents. It is concluded that low application rate of jellyfish fertilizer increased soil moisture and nutrient contents, consequently, enhancing the seedling growth.
Effects of organic manure and chemical fertilizer on soil fertility and productivity of plant and ratoon crops of sugarcane
A study was undertaken to evaluate the effects of integrated use of some organic manures and chemical fertilizers on soil fertility and productivity in plant and the subsequent ratoon crops of sugarcane. The manures included press mud, farmyard manure (FYM) and green manure (Crotalaria juncea) and the fertilizers were urea, TSP, MOP, gypsum and zinc sulphate. Application of organic manure in combination with chemical fertilizer increased absorption of N, P and K in cane leaf tissues both in the plant and ratoon crop as compared with chemical fertilizer alone. This led to higher cane and sugar yield of both crops. The maximum cane yield of 108.4 t ha − 1 and sugar yield of 9.47 t ha − 1 for the plant crop, and 96.8 t ha − 1 cane and 9.18 t ha − 1 sugar yields for the second crop (ratoon) were recorded where FYM at 15 t ha − 1 accompanied with chemical fertilizer (N178P53K54S26Zn2.6 kg ha − 1) were applied. The organic carbon, total N, and available P, K & S contents of soils increased slightly due to incorporation of organic manure. It appeared that 25% reduction of fertilizer application is possible if FYM or press mud at 15 t ha − 1 is used in plant and ratoon crops of sugarcane.
The Alzheimer's Disease Home Hospice Knowledge Scale: development, validity and reliability.
BACKGROUND
Several instruments are available to assess knowledge about hospice care, but none specifically address knowledge about home hospice for persons with Alzheimer's disease (AD).


AIM
To develop and validate the Alzheimer's Disease Home Hospice Knowledge Scale (AD-HHK-S).


METHODS
A total of 107 Israeli family caregivers of persons with dementia (mean age=71.2; 73% female) participated in the study.


RESULTS
The AD-HHK-S included 28 true/false items assessing 3 areas of knowledge: knowledge about hospice, knowledge about home hospice, and knowledge about home hospice for AD. Good internal reliability was found, with Cronbach alpha ranging from 0.72 to 0.85. Good face, construct and predictive validity were found.


CONCLUSIONS
The AD-HHK-S proved to be a valid and reliable tool to assess knowledge about hospice care in the area of AD. It might provide an effective tool for palliative care nurses to communicate with family caregivers of persons with AD at the end of life.
