Purpose/Aim: We aimed to investigate the effect of monocular blur on the binocular visual field. Materials and Methods: A total of 13 healthy young volunteers participated in this study. The mean subjective refractive error of the dominant eye (DE) was -3.33 ± 1.65D, and the non-dominant eye (NDE) was -3.15 ± 2.84D. The DE was determined by using the hole-in-the-card test. The visual field was examined by the Humphrey Visual Field Analyzer using the 30-2 SITA Standard program. The visual field was measured while wearing soft contact lens under three conditions;① both eyes: near vision correction;② DE: near vision correction +3.00D added, NDE: near vision correction;and ③ DE: near vision correction, NDE: near vision correction +3.00D added. The foveal threshold, mean deviation (MD), and pattern standard deviation (PSD) values were investigated. Results: The foveal threshold value (dB) at ①, ②, and ③ was 41.2, 37.8, and 38.1, respectively. The values at ② and ③ were both significantly lower than that at ① (p Conclusion: These results suggest that monocular blur reduced the sensitivity within the binocular visual field.

The exploration of the effects of pressure leads to new insights into the mycelial growth of Paecilomyces hepiali fungal strain. This strain has been generally accepted as true anamorph of wild Ophiocordyceps sinensis. It is only found at high altitude area like Himalayan plateau where atmospheric pressure is very low. Most of researches about P. hepiali and artificial mycelial cultivation have been done around mean sea level pressure. Then new experimental set up was developed and described. The apparatus permitted growth of mycelia under different pressure levels while other micro environmental conditions were carefully controlled. Potato dextrose broth was used as liquid media. As solid and semi solid media, sorghum base media and potato dextrose agar were prepared. Results of mycelial growth under hypobaric pressures and hyperbaric pressure were compared with mycelial growth of atmospheric pressure and hence growth influence has been shown. Specially, -100 mmHg treated sample showed significantly highest growth in both solid media and semi solid media. In semi solid media, -100 mmHg was not significant with other reduced pressure treatments. Meanwhile, -150 mmHg treated samples showed significantly highest mycelial growth of liquid media and -150 mmHg of pressure adversely affected on water contents of solid growing media. This may be an effect of pressure on enzymatic activities, protein and fatty acid of plasma membrane. As well as, pressure changes equilibrium of biochemical reactions, bond of some molecules and partial pressure of air molecules. Further molecular and biochemical researches are required to evaluate the possible stimulation of mycelial growth through hypobaric and hyperbaric treatments.

This paper presents the status of mushroom cultivation in Malawi. This is a developing country located in southeastern Africa between latitudes 9°25' South and 17°08' South and longitudes 33° East and 36°East. Almost all the mushroom cultivators in the country are growing Pleurotus ostreatus. This species is most preferred because of its easiness to cultivate using the low-cost cultivation method being practiced in the country. On average, the annual P. ostreatus production is estimated at 240 kg per grower. Mushroom cultivators are selling their produce at prices ranging from MK800 (USD2.04) to MK2000 (USD5.10) per kg. At present, there are four institutions that are producing spawn namely Bunda College (Lilongwe University of Agriculture and Natural resources), Bvumbwe Agricultural Research Station, Natural Resources College and the Biology Department at Chancellor College, University of Malawi. Currently, a total of about 1307 bottles (330 ml each) of P. ostreatus spawn are sold by these four spawn producers per month. Mushroom cultivation is not that popular in Malawi. This may be, partly, attributed to lack of know-how and awareness on the economic, nutritive and medicinal benefits of cultivated mushrooms. Some of the major supermarkets do sell Agaricus bisporus mushrooms which are imported from the Republic of South Africa. They also sell Pleurotus ostreatus sourced from local cultivators.

In this study, effects of hot water extract of Paecilomyces hepiali mycelia on hypertension parameters in spontaneously hypertensive rats (SHR) were investigated. The tested parameters included blood pressure, blood and urine biochemical composition, renin and angiotensin II levels in the blood. Prior to these tests, the extract was examined for toxicity. The fungus was cultivated in a solid medium composed of 40 g brown rice, 0.32 g glucose, 0.65 g sucrose, 2 g peptone and 65 ml corn steep liquor. No abnormality or harmful effects were observed in the toxicity test. Administration of a continuous-dose, once daily, to SHR for 27 weeks (from 13 weeks of age) decreased the systolic blood pressure (SBP) significantly. Levels of blood urea nitrogen, β-lipoprotein lipid peroxides and low density lipoprotein were significantly lower in the treated groups when compared to the control group. Urinary protein was significantly reduced in the middle and high dose groups. In comparison with the control group (0 mg/kg/10ml/day), significantly higher values were obtained for total cholesterol in groups that were given middle (170 mg/kg/10ml/day) and high (250 mg/kg/10ml/day) dosages. In all dosages (low, middle and high) the values for triglyceride were significantly higher than value found in the control group. In terms of angiotensin II levels, the value in the control group was markedly higher than values in the other groups. The results suggest that oral administration of hot water extract of P. hepiali mycelia has ability to control hypertension in rats.

Growth of?Paecilomyces hepiali?in various agar media and yield of fruit bodies in rice based media were?studied. The best growth in agar media was obtained at 25℃?(61.86 mm colony diameter in 14 days). The initial agar media pH range?from?6 to 8 was found to be?the?most favourable for mycelial growth. This study found that agars made with powders of cereal grains alone do not support good mycelial growth of?P. hepiali. Addition of peptone improved mycelial growth significantly. The most favourable carbon sources were Mannose, Fructose and Glucose. Organic nitrogen sources were found to be?the?most preferred. The results demonstrated that brown rice is better than polished rice in yield of fruit bodies. Addition of peptone was found to be quite significant in enhancing yield of fruit bodies. Peptone, as a supplement, gave a better yield than addition of egg yolk, albumen and a mixture of the two. The medium with?40 g brown rice, 0.325 g glucose, 0.65 g sucrose, 2 g peptone and 65 ml corn steep liquor was found to be?the?most favourable and it yielded 19.3 g of fresh fruit bodies.

Recently, the number of system interconnection of the renewable energy such as PV （photovoltaic） generation system and wind power generation system has been increasing drastically. A distribution system with the distributed generation must be operated keeping reliability of power supply and power quality. When high-capacity PV systems are interconnected to the distribution system, the system voltages may be deviated from the upper limit or lower limit of proper voltage in the distribution system. In this study, the authors propose a cooperative voltage control method of the distribution system by the power factor control of plural residential PV systems. In order to verify the validity of the proposal method, the numerical calculations are carried out by using an analytical model of distribution system which interconnected residential PV systems.

Recently, there is a movement that aims to realize a distributed energy system in Japan. The PV （photovoltaic） generation is especially expected, and it is anticipated that interconnection number of PVs will increase more and more ha the future. However, an amount of insolation is easily affected by the weather, the output of PV and the supply of electricity becomes unstable. And it causes various problems in a distribution system. Therefore, it is important to forecast the amount of insolation. In previous study, MLPNN （multilayer perceptron neural network） is a general method to forecast the amount of insolation. However, it is in danger of falling into a local solution by only MLPNN. In this study, the authors propose a forecasting method of amount of insolation using MLPNN and EPSO （evolutionary particle swarm optimization）. The authors use EPSO in addition to MLPNN to solve the problem. The authors also propose a forecasting method of amount of insolation using other regions weather data for the accuracy improvement.
