  • The majority of acute toxic poisoning occur via oral route. The most important emergency treatment of acute poisoning are gastric lavage. Gastric lavage should be considered a patient has ingested a potentially life-threatening amount of a poison and the procedure can be undertaken within 60 mins of ingestion. But, gastric lavage does not consist properly in the cases of emergency situation or an inexperienced doctors treat. The purpose of this study was to determine whether gastric lavage is performed properly. Eighty patients were enrolled in the study in 12-month period from January to December 2002. A retrospective chart review was performed on patients identified as drug overdose who admitted to ER. To assess whether there was a subgroup of patients who may have been candidates for the initiation of gastric lavage in the ER, the patients divided in two groups by time interval from toxin ingestion to ER arrival. The group 1 that admit within 60 minutes after drug ingestion was 38 cases ($47.5\%$), and the group 2 patient who admitted after 60 minutes was 42 cases ($52.5\%$). The average age was $44\pm19$ years in group 1, and $48\pm24$ years in group 2. There were no differences in sexual distribution of two groups. The mean time interval was $49\pm20$ minutes in the group $1,258\pm190$ minutes in the group 2. Only thirty ($37.5\%$) of the patients had an overdose for which the treatment of gastric lavage was potentially feasible according to guideline. The correctly performed gastric lavage was 18 ($47.4\%$) in group 1, 12 ($28.6\%$) in group 2. We must enforce education about the gastric lavage, and do so that may treat according to guideline.

  • This study was carried out to provide the geographic information based on the distribution of rice qualities and palatability in Gyeoungbuk province of Korea. The rice grain quality and environmental factors were analyzed using 513 sampling sites based on different five-agroclimtic regions of Gyeoungbuk province during three years from 2002 to 2004. In rice grain quality characteristics, the average palatability was low in South eastern coastal and Tabaek semi alpine regions as $67.6\~68.3$ and the coefficient of variation (CV) was relatively high as $6.2\~7.4\%$. The average head rice rates were low in South and Central eastern coastal regions as $87.3\~88.2\%$ and CV was high as $8.2\~8.3\%$. The average protein content was high in Central eastern coastal regions as $8.0\%$ and CV was high as $8.2\~8.3\%$. In case of palatability, the variation was differed clearly between high and low agroclimatic regions; it means that it is possible to divide the same agroclimatic region of high CV into two or three areas by CV of palatability. As the results of subdividing each existing agroclimatic regions based on the palatability, the variation of grain quality characteristics was become lower than that of existing five-agroclimatic regions. Therefore, the re-establishing of agroclimatic region based on rice grain quality was very important for precise cultivation for rice.

  • A sensor network which uses DCS(Data-Centric Storage) stores the same data into the same sensor node. Thus it has a hot spot problem when the sensor network grows and the same data arise frequently. In the past researches of the sensor network using DCS, the hot spot problem caused by growing the sensor network was ignored because they only concentrated on managing stored sensor data efficiently. In this paper, we proposed a non-equal region split method that supports efficient scalability on storing multi-dimensional sensor data. This method can reduce the storing cost, as the sensor network is growing, by dividing whole space into regions which have the same number of sensor nodes according to the distribution of sensor nodes, and storing and managing sensor data within each region. Moreover, this method can distribute the energy consumption of sensor nodes by increasing the number of regions according to the size of the sensor network, the number of sensor nodes within the sensor network, and the quantity of sensor data. Therefore it can help to increase the life time and the scalability of the sensor network.

  • BACKGROUND: The fruit quality and flowering characteristics of Kiwifruit (A. deliciosa cv. Hayward) in the following year is known to be affected by the extent and timing of defoliation of the current year. In korea, the production of kiwi, which is a perennial, straggling deciduous warm-temperate fruit, is often restricted by wind damage due to typhoons resulting to defoliation at the middle season of its growing period. In this paper, we report the effect of the different timing of defoliation and severities at the current season to the kiwifruit quality. METHODS AND RESULTS: Twenty seven-year-old 'Hayward' trees grown under polyethylene film rain-shelter were defoliated in different days from August to September at seven day-intervals. In each day, 0, 25, 50, 75 and 100% of leaves were removed from the trees. Fruits from each treatment were classified into four floating types (L: lying in bottom, S: standing on bottom, F: floating and SF: floating at the surface of water) by submerging them into tap water. Defoliation of kiwifruit trees in August and September caused air holes in locules of inner pericarp. Increased number of air hole in locules of a fruit was observed in floating types F and SF, and most of the air holes were located in stem end. The defoliation of trees in August significantly reduced the ratio of L-floating type fruits, which have the least number of locule air holes. The extent of defoliation also affected the distribution of the four types, the more leaves removed, the less L-floating type fruits harvested. The weight of fruits from trees defoliated in August was lower than that of fruits from September. Soluble solids content decreased as the number of locule air holes increased. Negative correlations were observed between the extent of defoliation and the weight and soluble solids content of fruits. CONCLUSION: Early defoliation effect on kiwifruit locule air hole occurrence and fruit quality were more severe in August than in September. And also if the defoliation severity is over 25%, severe fruit quality reduction expected to happen due to increase of fruit locule air hole in the inner pericarp.

  • This study aims to investigate the flora and the vegetation of Dokdo (Dongdo). The vegetation types were investigated by the Z-M school method. A total of 44 vascular plant taxa belonging to 24 families, 41 genera, 36 species, and 11 varieties are recognized in Dongdo, Dokdo. In this study, we confirmed four species, Chenopodium serotinum, Chelidonium majus var. asiaticum, Bromus japonicus, Elymus sibiricus, that had not been previously reported. The biological type of Dokdo was determined to be $Th-D_4-R_5-e(b)$ type. Two main vegetation groups which were established in a rocky area with little soil development and in a developed soil layer, along the development of soil layer have been distinguished and classified into five communities. The former was composed of 1 community; Aster spathulifolius-Sedum oryzifolium community. The latter was composed of 4 communities; Agropyron tsukusiense var. transiens community, Festuca rubra-Artemisia japonica ssp. littoricola community, Miscanthus sinensis community, and Artemisia princeps community.

  • With the rapidly increasing population density and development of infrastructure, the loss of life and property damage caused by landslides has increased gradually in urban area. Especially, Because Busan has high percentage of mountainous terrain among the metropolitan in Korea, it is unavoidable to develop mountainous region excessively. The objective of this evaluation is to study on landslide hazard possibility for Mt. Hwangryeong in Busan Metropolitan City using the infinite slope model considering the groundwater level. All data related to creating the thematic maps was carried out using ArcGIS 10.0. The results show that FS (Factor of Safety) for landslide is inversely proportional to groundwater level change as expected. Most area indicates stable state in dry condition, and unstable area increase due to high pore water pressure when the groundwater level rise. However, several places in high lineament density area where landslide has been previously occurred, are more stable than other places according to the analysis. This inconsistency between real situation and analysis results indicates that additional analytical method would be necessary to solve the problem. Therefore, we suggest that development of new infiltration theory for unsaturated zone would be helpful to evaluate groundwater level distribution as time goes by.

  • We investigated the pH, volatile basic nitrogen (VBN), microbial changes and dominant microbes in raw beef, wet-aging beef, and dry-aging beef after the meat had been stored in a refrigerator. The count of mesophilic bacteria was 3.3-3.9 log CFU/g in raw beef and dry-aging beef, and 5.4 log CFU/g in wet-aging meat. After 18 days of refrigeration, the mesophilic bacterial count in raw and aging beef increased to 6.1-6.4 log CFU/g. In wet-aging beef, the number of lactic acid bacteria increased from 4.5 log CFU/g to 6.0 log CFU/g at refrigeration temperature. However, lactic acid bacteria were not detected in dry aging beef. Major foodborne pathogens such as Salmonella spp, Listeria monocytogenes, and Escherichia coli (EHEC) were not detected. Based on the legal standard for mesophilic bacteria count, the estimated shelf-life of aged beef was less than 12 days and the average VBN was 15 mg%. The dominant microorganisms varied between the different types of meat. In raw meat, Staphylococcus saprophyticus was the dominant microorganism, and as the VBN increased, Carnobacterium divergens dominated. In wet-aging beef, Carnobacterium divergens dominated during the initial days of refrigeration after which the number of Lactobacillus sakei increased. Dermacoccus nishinomiyaensis was initially the dominant microbe in dry-aging beef, after which Pseudomonas fragi dominated. In addition to the role of specific bacteria in the early stage of decay, it is thought that microorganisms can be utilized for safe distribution and storage of matured meats by conducting research on changes in rot, fragrance analysis, and changes of ingredients in matured meats.

  • To develop the diet for Korean type 2 diabetic patients, a consumer survey was conducted (N=35) and was analyzed statistically. The survey compared the results of a questionnaire, somatometry, and blood parameters before and 8 weeks after the experiment. It was divided into Diabetic diet enforcement group (DDE) vs. Non diabetic diet enforcement group (NDDE). There was no significant difference in body weight, body mass index (BMI), body fat, triglyceride (TG) and low density lipoprotein cholesterol (LDL-C) of the subjects before and 8 weeks after the experiment. DDE's average fasting glucose (FBG) and post prandial 2 hours blood glucose (PP2) were significantly decreased before and after the experiment (p<0.05). NDDE's average FBG and PP2 showed no significant difference. In terms of Hemoglobin $A_lC\;(HbA_1C)$ content, DDE's had significantly decreased level both before and after the experiment (p<0.05), while there was no significant difference in the NDDE group. Cholesterol and High density lipoprotein cholesterol (HDL-C) were significantly different in DDE (p<0.05) both before and after the experiment. Whereas in the case of NDDE, there was no significant difference on the cholesterol and HDL-C, while DDE's showed a significant difference before and after the experiment. In terms of patients distribution depending on their treatment (p<0.05), NDDE had no significant difference before and after the experiment. For an item asking blood glucose control, DDE had significant difference before and after the experiment (p<0.01), while NDDE had no significant difference. For program satisfaction (p<0.05) and health (p<0.001), both the groups changed significantly after the experiment. But there was no significant difference in applying it to their real life after the experiment. Based on these results, DDE had the decreased blood glucose levels, $HbA_1C$, and cholesterol and increased HDL-C, with decreased rate of the patients taking oral hypoglycemic agents. In addition, many of the patients who participated in the experiment were found to be satisfied with the program, in terms of having less trouble in glucose control and exhibited improvement in health. Hence, based on the above results it was concluded that program was a very successful one for the treatment of diabetes.

  • The effects of organic acids mix (0.4%) and modified atmosphere packaging (MAP) on the storage quality of sliced bacon were investigated. Pork bellies were treated with or without organic acids at the curing stage. The organic acids mix comprised 35% sodium acetate, 25% salt, 15% calcium lactate, 11% trisodium citrate, 7% ascorbate, and 7% citric acid. The cured pork bellies were smoked and packaged with 50% $CO_2$ + 50% $N_2$ (50% $CO_2$-MAP) and 100% $N_2$ (100% $N_2$-MAP), and stored at $5^{\circ}C$ for 14 d. The 50% $CO_2$-MAP showed a higher pH value (p<0.05) up to 10 d, a lower protein deterioration (p<0.05) as measured by volatile basic nitrogen (VBN) from 6 to 14 d, and a higher color value of lightness (CIE $L^*$) compared to 100% $N_2$-MAP. The development of lipid oxidation measured by thiobarbituric acid reactive substance (TBARS) values seemed to be effectively controlled throughout the storage period in both 50% $CO_2$-MAP and 100% $N_2$-MAP regardless of the application of organic acids. The 50% $CO_2$-MAP inhibited the growth of aerobic and anaerobic bacteria (p<0.05) both in non-added and bacon added with organic acids mix. The 50% $CO_2$-MAP alone seemed to be effective in delaying the growth of bacteria since the use of organic acids mix gave no additional effects. The addition of organic acids mix lowered the pH value (p<0.05), effectively retarded the protein deterioration (p<0.05), and showed a higher color value of lightness (CIE $L^*$) value (p<0.05) and lower color value of redness (CIE $a^*$) value (p<0.05). In conclusion, 50% $CO^2$-MAP showed better quality and self-life of sliced bacon during storage. However, the beneficial effect of organic acids mix was not noticed in the concentration used in this experiment.
