  • It is difficult to check the exact building energy consumption reduction such as when green remodeling of buildings, because it is due to outdoor air temperature over the years. And in Korea although Big Data of building energy consumption is collected and managed through "The Information System of the Building Energy and Greenhouse Gases" it is underutilized because of non calibration of outdoor air temperature change. Therefore, this study aims to develope calibration method of building energy consumption by outdoor air temperature according to micro climates, and building use types. As a result of analysis, Regression equations of Building energy consumption and $HDD_m/CDD_m$ are derived and calibration method is developed by Regression coefficient.

  • Objective: This study aimed to ascertain the curative effects of Gamisipjeon-tang (GST) used for wound healing on the skin regeneration of deep second degree burns in mice. Material & Methods: In vitro, the $I{\kappa}B$ kinase (IKK) mRNA expression, inducible nitric oxide synthase (iNOS) mRNA expression, and cyclooxygenase-2 (COX-2) mRNA expression in the GST concentration from 1 mg/$m{\ell}$ to 10 mg/$m{\ell}$ were measured. In vivo, the mice were divided into four groups : the normal group, the BE group (burn-elicited group, control group), the DC group (Duoderm CGF-treated group after burn elicitation), and the GST group (Gamisipjeon-tang treated group after burn elicitation). To determine the anti-inflammatory effects, nuclear factor (NF)-${\kappa}B$ p65, iNOS, COX-2 positive reaction were measured by immunohistochemistry. To estimate the skin regenerative effects, change of burn area, 5-bromo-2'-deoxyuridine (BrdU), and fibroblast growth factor (FGF) positive reaction were analyzed. Results: In vitro, the iNOS, IKK, COX-2 mRNA expression decreased according to the increase of GST concentration. The significant decrease of COX-2, iNOS, NF-${\kappa}B$ positive reaction were the highest in the GST group, followed by the DC group and the BE group (p<0.05). The diameter of burn area was significantly decreased in the GST group as compared to that in the DC and BE group (p<0.05). The BrdU and FGF positive reaction increased more significantly in the GST group than in the DC group, and more significantly in the DC group than in the BE group on the 3rd and 7th day after burn (p<0.05). FGF positive reaction increased in the BE and DC group, whereas it decreased significantly in the GST group on the 14th day (p<0.05). The BrdU positive reaction increased in the BE group, whereas it decreased significantly in the DC and GST group on the 14th day (p<0.05). Conclusions: This study shows that GST could decrease the inflammatory response and accelerate the skin regeneration as compared to the duoderm CGF in mice with deep second degree burns.

  • To evaluate growing degree days(GDD) as an index of growth duration of rice plants, 30 days old seedlings of 16 japonica and 14 indica/japonica varieties were transplanted six times from May 10 at the 10-day intervals at Gyeongsan in 1982. The number of days from transplanting to heading decreased as transplanting dates delayed in all japonica varietie and 4 indica/japonica varieties but that of 10 indica/japonica varieties decreased up to June 9 or June 19 transplantings and then it levelled off or increased with further delay of transplanting. However, GDD requirement was similar among transplanting dates at appropriate base temperatures; GDD could be better than calendar day system to classify maturity of varieties especially grown in a wide range of climatic conditions. Required GDD from transplanting to heading of all indica/japonica and early japonica varieties showened a smaller coefficient of variation (CV) compared to longer season japonica varieties. Among GDD methods, an accumulation of daily Max + Min temp./2 -$l0^{\circ}C$ showed the smallest CV for the duration from transplanting to heading, but for ripening period GDD calculated with adjusted maximum temperature when it was higher than $30^{\circ}C$ showed the best results. Heading date did not affect required GDD for maturity of japonica varieties, but in indica/japonica varieties GDD decreased as heading date delayed; at late transplantings ripening period of indica/japonica varieties was less extended compared to japonica varietes due to a decrease in grain weight.

  • 1. By feeding on high Peroxidation Value(POV : 90.4mEq/kg) diets for 180 days, the cultured flounder were induced ceroidosis antificially. 2. The supplementation of glutathione to the diets having POV of 15.5mEq/kg improved the growth of the flounder that had shown depressed by the previous high POV diets(90.4mEq/kg). However, we found very much the same degree of improvement on growth by the supplemented diets of glutathione from 10mg/kg/day to 40mg/kg/day. 3. After 7 days, the flounder fed on the diets supplemented with 10, 30mg/kg/day glufthione start the recover from the accumulated ceroid and damaged tissues. These treated flounders with glutathione showed completely normal histlogical signo after 21 days. The effect of glutathione treatment with high concentration(30mg/kg/day) was better than that of low concentration(10mg/kg/day).

  • Objectives: Herniated Intervertebral Disk(HIVD) of L-spine is one of the most common diseases that cause back pain and radiating pain. The aim of this study is to find out if the acupuncture therapy combined with Soyeom Pharmacopuncture therapy can improve the symptoms of the patients suffering from the disease more effectively than the acupuncture only therapy. Methods: We separated 30 patients into two groups. Group A was treated with the acupuncture only therapy, and Group B was treated with Soyeom Pharmacopuncture therapy in addition to the acupuncture therapy. We have observed patients for 7 days. We checked the Visual Analog Scale(VAS) for 4 times and did Straight Leg Raising Test(SLRT) twice. Results: 1. For 7 days from the admission day, the VAS score has been decreased significantly in both Group A and Group B. 2. For 7 days from the admission day, the VAS score of Group B has been appeared signifi cantly lower than that of Group A, so that we can know that patients in Group B has more rapidly improved than patients in Group A 3. From the admission day to the 3rd hospital day, the improvement index of VAS scroe of Group B has appeared significantly higher than that of Group A, but after 5th hospital day, there was no significance between the improvement index of VAS score of Group A and that of Group B. 4. For 7 days from the admission day, the SLRT(degree) has been improved significantly in both Group A and B, but there was no significance between the SLRT(degree) of Group A and that of Group B. Conclusion: We can use Soyeom Pharmacopuncture therapy with acupuncture therapy to make the patients suffering from back pain and radiating pain improve more rapidly.

  • The frost penetration depth of pavement is usually estimated from the freezing index that made temperature data analysis of 30 years and decided the thickness of anti-frost layer. The field monitoring region in study was divided into five regions by freezing index 550~650$^{\circ}C{\cdot}$day, 450~550$^{\circ}C{\cdot}$day and 350~450$^{\circ}C{\cdot}$day. Each region has three-section of road pavement such as cutting area, boundary area of cutting and banking, and lower area of banking. The field monitoring system was established both in the section of anti-frost layer and in the section without anti-frost layer. The data analysis was conducted for determination of frost penetration depth within the paved road by the field monitoring system. The result showed that The temperature of subgrade without anti-frost layer shows below zero in centigrade for the region of freezing index 550~650$^{\circ}C{\cdot}$day, up and down around zero degree in subgrade for the region of freezing index 450~550$^{\circ}C{\cdot}$day, and there is no place existed below zero degree in subgrade for the region of freezing index below 450$^{\circ}C{\cdot}$day. With comparison of field frost penetration depth for the cross-sections of pavement, the cutting area shows the greatest frost penetration depth, and less influence of frost penetration depth for the boundary area of cutting and banking, and the least influenced for the lower area of banking.

  • Highly Activated Calcium(below HAC) is the oxidized calcium made by dissolving shell materials with high voltage about 15,000V and high temperature ($1,500{\sim}5,000^{\circ}C$). This HAC is a material with a very high degree of purity without toxicant. This HAC decreases chemical reaction so the degree of being active and dissolving living material is outstanding. The effects of HAC on the propagation of mushrooms are following. In the case of the Pleurotus ostreatus, when controlling media moisture by mixing with the HAC, mycelium cultivating days were shortened by 2days. The day required for primordial formation after inoculation(DPI) were one day faster. The number of stem was 15 and individual weight was 248g/850cc, a 6.5% increase. In the case of Pleurotus eryngii, when controlling media moisture by mixing with the highly activated calcium, mycelium cultivating days were shortened by 3days. DPI were l day faster. The day required for colonization after inoculation was shortened by 6days and individual weight was 108.8g/850cc, a 9.7% increase. In the case of Flammulina velutipes, the highly activated calcium was the best for scraping up mycelium. Mycelium incubating days were shortened by 2days. DPI were shortened by 3days. The day required for colonization after inoculation was 1day faster and the period of cultivation was shortened by 3days. Individual weight was 165g/850cc, a 6.7% increase. In the case of Lentinula edodes, when mixing media with the highly cultivated calcium, cultivating days were shortened by 3 days. The days for becoming brown in color were 2 days faster and the days of the first harvest were shortened by 4 days. The weight of mushrooms was 169g/2kg, a 9.7% increase.

  • Purpose: This study aimed to investigate the degree of discomfort and to identify factors related with discomfort in patients wearing thigh-length compression stockings after orthopedic surgery. Methods: The participants were 105 patients wearing thigh-length compression stockings after orthopedic surgery at two hospitals in B city. Data were collected by the scale of discomfort in wearing compression stockings from July 5 to October 20, 2011. Results: Mean score of discomfort on wearing compression stockings was significantly higher at post-op. day 3 than day 1 (t=-2.30, p=.004). Discomfort scores for 'itching skin' and 'tightened leg' items were higher than others. There was significant difference in discomfort at post-op. day 1 according to surgical regions. The total score of discomfort at post-op. day 3 was positively related with the body mass index (r=.20, p=.041). Conclusion: Wearing thigh-length compression stockings to prevent deep vein thrombosis may cause physical and psychological discomfort for orthopedic surgical patients. To reduce discomfort in wearing compression stockings, nurses need to intervene discomfort and problems related to the stockings post-operatively.

  • The authur surveyed the caries experience of 108 preschool children and collected their five-day dietary data, and evaluated the cariogenicity applied to their diets and discussed the relationship between their caries experience and their diet. The results were as follows: 1. As a frequency of consumption of cariogenic foods by degree of retentiveness, highly retentive foods like sugars and dried fruits had been taken once every 3 days, next highly retentive foods like confections and breads had been taken once everyday, slightly retentive foods like ice-creams and fermented milk also had been taken once everyday, and low retentive foods like soft drinks had been taken once every 6 days. 2. The highest caries experienced children ingested more frequently retentive foods like ice-creams, fermented milk and sugars than the lowest caries experienced children. 3. As a potential cariogenicity, the mean number of cariogenic ingestions in a day was 2.26, the mean retentiveness in a day was 5.93, and the mean cariogenicity score per ingestion in a day was 2.51. 4. The highest caries experienced children had higher values in the mean cariogenic ingestions, the mean retentiveness, and the mean cariogenicity score than the lowest caries experienced children.
