The low temperature storage method has been used to increase the value of agricultural products by reducing quality deterioration and controlling respiration rate. The respiration rate of agricultural products depends on several factors such as temperature, moisture, gas composition and microbe inside the storage room. Among that temperature is the most important factor, which affects respiration rate and causes severe damage. The results obtained from these experiments are that electric consumption is decreased as setting temperature is decreasing and temperature deviation is increasing. In the ventilation experiment, the case ventilated four times a day(every six hours a day) with ten minutes operation each time, was inspected require as much electric consumption as non-ventilation case.

The heat performance in a forced circulating cool storage room was numerically investigated. A commercial PHOENICS package was used to simulate 3-D airflow. For solving the governing equations a standard k-ε turbulent model was implemented to calculate steady state turbulent velocity and temperature distributions. The results show that the large air contacting area of products increases the storage quality, because the airflow between products helps to remove the heat from the products by convective heat transfer.

Many of the growth-promoting properties of growth hormone(GH) are mediated by insulin-like growth factor-I(IGF-I), a highly conserved circulating 70-amino acid peptide. Recent studies have shown that multiple mechanisms influence IGF-I gene expression, including transcription from two promoters, alternative RNA splicing, and variable polyadenylation. In thyroid tissue, thyroid stimulating hormone(TSH) and IGF-I are the most possible candidates for follicular cell proliferation and hypertrophy. Actually IGF-I had autocrine and paracrine effect for tissue growing. We prepared thyroid tumor tissue mRNAs using single step method for detecting IGF-I levels according to different tissues, i.e., thyroid adenoma or papillary thyroid carcinoma. We used Northern blot analysis for IGF-I mRNA and RNase protection assay (RPA) for IGF-I transcription start sites. For Northern blot, we used whole human IGF-I cDNA as a DNA probe and for RPA, we used IGF-I exon 1 containing noncoding promoter 1 as a riboprobe. We got good RNA bands from Northern blot analysis around 1 kb (IGF-IA) and 7.5 kb (IGF-IB) region. To clarify the amount of both IGF-IA and IB mRNAs, we measured autoradiographied signal of IGF-I mRNAs bands using densitometer. In IGF-IA signals, there's no change among liver and thyroid tissues, but in case of IGF-IB mRNA bands, the signal was markedly increased in thyroid carcinoma tissues than that of normal thyroid tissue (85% vs 14%). In the study of RPA, all thyroid tissues used the same transcription start sites as those of liver's. We concluded that that this different regulation of IGF-I mRNA was originated from tissue specificity. That meant some tissue specific transcription factor/s were related to tissue IGF-I expression.

Koh, Young-Jin,Lim, Myoung-Taek,Jeong, In-Ho,Kim, Gyoung-Hee,Han, Tae-Woong,Cha, Ju-Hoon,Shin, Jong-Sup The Korean Society of Plant Pathology 2007 Plant Pathology Journal Vol.23 No.4

A survey of the occurrence of abiotic diseases on kiwifruit (Actinidia deliciosa) trees was conducted at sixty-two kiwifruit orchards in twenty-one locations of Jeonnam and Jeju Provinces in Korea during the 2007 growing season. Various kinds of abiotic diseases were detected on the kiwifruit trees. Malformed fruits caused by incomplete pollination were commonly observed among the normally growing fruits on almost all of the kiwifruit trees examined. Fruits imbued with wire rust, fruits scratched or girdled by the wire and fruits injured by sunscald occurred in all of the examined orchards. Abnormal growth of girdled branches by the fence wire, dead trees killed by excessive soil moisture due to poor draining and leaf chlorosis by nutrient deficiencies were found in some orchards. Leaf spotting by herbicide and leaf scorch or blight by excessively high temperature were observed. Leaf blight on young shoots by late frost and bark split on trunks by freeze occurred in several open-field orchards. Flooding and strong wind damages by attack of typhoon 'Nari' were also found during the survey period. Cup-shaped leaves frequently occurred on young shoots in early spring and the incidence of the syndrome tends to increase annually in recent years, which are not etiologically defined until now.

N/A Objectives: In the consideration of the variabilities of the test results related to the technical or the biologic factors, the standardized methods performing the ventilatory lung function test by spirometry were recommended by American Thoracic Society (ATS). However, even though most of the modern pulmonary function laboratories perform the lung function tests using the computerized standard spirometers and the standard performing methods, it is necessary to evaluate the intraindividual technical variabilities of the spirometric test results; in addition, there is no article about it published in Korea. Methods : The lung function tests of 13 normal subjects were performed in each laboratories of Chonnam University Hospital, Wonkwang University Hospital, and Kwangju Christian Hospital. Results: 1) The interlaboratory variability of the spirometric test results was significantly larger than the intralaboratory(Coefficients of Variation, CV: 7.25 ±5.33% vs 2.79±1.59%, p<0.05 in FVC; 7.23±5.22% vs 2.26±1.70%, p<0.05 in FEV₁). 2) The mean lung function test results measured by one machine were significantly larger than those by another(4.29±0.89L vs 4.13±0.90L, p<0.05 in FVC; 3.71±0.81L vs 3.51±0.80L, p<0.05 in FEV ,). However, the intermachine variability was not significantly different from the intramachine. 3) The intertechnician variability of spirometric test results measured by three different technicians was not significantly different from the intratechnician. 4) The significance level of intraindividual difference in spirometric test results were 12% in FVC and 12% in FEY, between the different laboratories, 5% in FVC and 6% in FEV₁, between the different machines, 3% in FVC and 4% in FEV₁, between the different technicians. Conclusion : These results suggest that the spirometric test must be interpreted cautiously under the consideration of such a variability, and that it is necessary to adhere strictly to the recommended methods of the equipment quality control and the maneuver performance, and to check regularly the inter and intralaboratory variabilities,
