Maize hybrids were planted on April 1, April 25, May 20 and June 15 in 2012, 2013 at the experimental paddy and upland fields in Suwon city , respectively to know changes of growth stage and yield according to different planting time. Maize planting on April 1 was not recommended because total growing days at planting on April 1 was not different with that at planting on April 25 due to many days from planting to emergence over 20 days at planting on April 1. Total growing days were not much different among three planting time after April 25 because days from silking to maturity was lengthened though days from planting to silking was shortened at later planting time. Stalk weight was decreased as planting time was delayed, particularly at planting times after May 20 at paddy field by excess water injury during early growth stage. But, grain yield was not low as in May and June. It is needed to introduce early maturity maize variety as Yanganok at late planting for higher grain yield and enough time for soil preparation for next winter crops

The purpose of this study was to develop survey tools for diagnosis of capacity levels in business promotion of rural residents when performing a rural development project of a regional unit. The cases of previous studies were analyzed to select community capacity indicators related to a rural development project. Five indicators were derived : social capital, consciousness of participation, community spirit, and leadership. Based on the five indicators, measurement items of various capacities were selected and 54 survey items were selected through evaluation of experts twice. The pilot tests were conducted and targeted at Jeonnam song ho-jung village and Gyeongnam Haegeumgang village to identify derived survey items. In addition, descriptive statistic analysis and reliability analysis were conducted. As a result, survey items were corrected by reducing 10 items of the total 54 items. This results showed that using this tool could help us understand capacity levels of rural residents.

Lee, Sang Choel,Han, Seung Hyeok,Li, Jin Ji,Lee, Sun Ha,Jung, Dong-Sub,Kwak, Seung-Jae,Kim, Seung Hye,Kim, Dong Ki,Yoo, Tae-Hyun,Kim, Jin Hyun,Chang, Se-Ho,Han, Dae Suk,Kang, Shin-Wook International Society of Nephrology 2009 Kidney international Vol.76 No.8

Heme oxygenase-1 (HO-1) is an anti-oxidant enzyme normally upregulated in response to oxidant injury. Here we determined the role of HO-1 in podocyte apoptosis in glomeruli of streptozotocin-treated rats and in immortalized mouse podocytes cultured in media containing normal or high glucose. HO-1 expression, its activity, the ratio of Bax/Bcl-2 protein, and active caspase-3 fragments were all significantly higher in isolated glomeruli of diabetic rats and in high glucose–treated podocytes. These increases were inhibited by zinc protoporphyrin treatment of the rats or by HO-1 siRNA treatment of the podocytes in culture. The number of apoptotic cells was also significantly increased in the glomeruli of diabetic rats and in high glucose–treated podocytes. Inhibition of HO-1 accentuated the increase in apoptotic cells both in vivo and in vitro. Our findings suggest that HO-1 expression protects against podocyte apoptosis under diabetic conditions.

Background : Pneumocytitis cainii pneumonia (PCP) can occur in immunocompromised hosts especially such as AIDS or cancer patients. Although recent research had focused on PCP in AIDS patients, few studies have described the clinical presentations of PCP in recipients of stem cell transplantation (SCT). We evaluated the clinical manifestations of PCP in SCT patients admitted at St. Mary's hospital, Seoul, Korea. Methods : The medical records of 17 PCP patients undergoing SCT between Feb. 1998 and Feb. 2000 were reviewed. The diagnosis of PCP was confirmed through the demonstration of Pneumocytitis cainii via either cytology of brochoalveolar lavage (BAL) or histological technique of lung biopsy. CMV disease and CMV infection were confirmed by BAL culture and antigenemia respectively . Results : Seventeen patients were all recipients of allogeneic SCT and 7 of 17 patients were performed non-sibling SCT. Patients presented with symptoms including brief period (4 ∼23 days) of fever (76%), dyspnea (70%), cough (64%), and signs such as rare(58.8%), Sixteen patients (94%) had been receiving immunosuppressive agent such as cyclosporine A (64%) or Fk506 (35%) without PCP prophylaxis. Eleven patients (64%) were treated with corticosteroid with mean dose of 16 mg/day prednisolone and mean duration of 4.6 months after post-SCT period. Twelve patients were co-infected with CMV. Another co-infected miCroorganisms were Pseudomonas aeruginosa, Mycobacterium tuberculosis, herpes simplex virus, parainfluenza virus, Average duration of treatment with trimethoprim-sulfamethoxazole (TMP/SMX) was 21 ±9 days. Four patients died, and three of them were related with PCP. Conclusion : PCP developed frequently in patients who were taking immunosuppressive drug due to graft versus host disease or were not taking TMP/SMX prophylaxis. High risk patients showing fever, cough, or dyspnea should be considered to take early bronchoscopic intervention for detection of PCP. When treat for PCP, it also be considered to the possibility of coinfection such as CMV. (Korean J Infect Dis 33:273∼279, 2001)

Purpose: The purpose of this study was to investigate the relationships between the degree of smart phone addiction among adolescents and their depression and anxiety levels. Method: In this study, 379 high school students were selected using the convenient sampling method. The instruments used for this study were smart phone addiction measure, the CES-D (Center for Epidemiological Studies-Depression Scale), and the STAI (State-Trait Anxiety Inventory). Data were analyzed using the SPSS 20.0 program with descriptive statistics, t-test, ANOVA with Scheffe test, and Pearson’s correlation coefficient. Result: The mean score for smart phone addiction was 40.45±17.27, depression was 36.56±9.58, state anxiety was 44.00±9.61, and trait anxiety was 45.70±9.75. There were significant differences between the degree of smart phone addiction and the following variables: gender (t=-4.953, p<.001), hours of smart phone use per day (F=12.259, p<.001), types of frequently used features (F=3.485, p=.008), and satisfaction level for smart phone (F=5.18, p<.001). There were statistically significant relationships (p<.001) among degree of smart phone addiction, depression level, and state and trait anxiety levels. Conclusion: The results of this study suggested that there was a significant relationship between smart phone addiction and mental health, specifically, depression and anxiety among adolescents. Further research is needed to develop nursing strategies to provide care for adolescents who frequently utilize smart phones.

This research is aimed at implanting confidence in solving obesity to growing obese children, haying them maintain dietary habit, and providing a method to early control factors of losing weight and developing adult diseases by understanding the status of their weight control, and applying behavioral correction therapy and constant exercise habit for managing the obese child's weight. For this, 80 students with over 20% obesity (male'40, female . 40) using 50 percentile value of weight by Korean children measured by Korea Podiatric Association in 1985 were sampled among the students attending a primary school located at K City, and 10 male and female students were randomly participated at the 4 groups of aerobic exorcise therapy, behavioral correction therapy, combined behavioral correction and aerobic exercise therapy, and comparison group for 12 weeks, and its difference between groups analyzed, then following conclusion was obtained. The group whose weight and physical fat were reduced most at the 12 week program was at both male and female students who carried out the combined behavioral correction and aerobic exercise therapy. At both male and female groups, the biggest weight loss was indicated between 8 weeks and 12 weeks. As for the physical fat of male and female students in terms of the program application term, the group whose physical fat was most reduced was that carried out combined aerobic exercise therapy and behavioral correction therapy, which was statistically significant. In the measurement time, physical fat was most reduced between 8 weeks and 12 weeks. The measurement of physical fact during the program's application was generally more in male students than female students. As for the maximum and minimum blood pressure of male and female students, the group carrying out the combined aerobic exercise therapy and behavioral correction therapy was reduced most, and the descending highest rate was the exercise therapy group, behavioral correction therapy group, comparison group, which was statistically significant.. As for total cholesterol (TC) of blood fat, the group at both male and female students that reduced it most was that who carried out the combined aerobic exercise therapy and behavioral correction therapy, which was statisticalIy significant. As for high density fat (HDL) of male and female students, the group carrying out the combined aerobic exercise therapy and behavioral correction therapy increased most and the descending highest rate was the aerobic exercise therapy group, behavioral correction therapy group, comparison group, which was statistically significant. As for neutral fat (TG) of male and female students, the group reducing it most was that who carried out the combined aerobic exercise therapy and behavioral correction therapy, which was statistically significant. In measurement time, TG volume was reduced most between 4 weeks and 8 weeks. As for low density fat (LDL) of male and female, the group reducing it most was that who carried out the aerobic exercise therapy and behavioral correction therapy. It was statistically significant in terms of program application period. The groups reducing calorie intake amount most was those who carried out the aerobic exercise therapy and the behavioral correction therapy, and the descending highest rates were the behavioral correction therapy, the exercise therapy group, the comparison group. Both male and female students reduced calorie intake amount most between previous term and 4 weeks.

In order to apply a sacrificial anode cathodic protection system for automotive muffler materials, determination of reliable sacrificial anode and its protection ability were evaluated by laboratory tests in synthetic condensed water. Three kinds of sacrificial anodes were selected: aluminum (AI), zinc (Zn) and magnesium (Mg), and the muffler materials were Al-coated steel and uncoated steel. The corrosion behavior in synthetic condensed water for the muffler materials and sacrificial anodes was investigated by potentiodynamic tests. The cathodic protection ability was evaluated by galvanic corrosion test and weight-loss test. The results of the potentiodynamic test indicated that Al was less suitable for sacrificial anode because it became passive. Mg was also unqualified due to the high dissolution rate. However, Zn was adequate for sacrificial anode because of its low dissolution rate, high stability and suitable potential difference. Results of weight-loss test demonstrated that the corrosion rate of Al-coated steel was reduced from 0.028 to 0.018 mm/year, and that of uncoated steel was 0.08 to 0.002 mm/year by coupling with Zn anode. In addition, the proper area ratio of anode to cathode was 1 : 10. From these results, it can be concluded that Zn anode can protect both the Al-coating with passivation, and steel substrate with low dissolution rate. (Received January 8, 2004)

To elucidate the hematologic alterations in Korean hemorrhagic fever(KHF), hemoglobin concentration, reticulocyte percent, platetet count, fibrinogen concentration, fibrin degradation product(FDP), prothrombin time(PT) and partial thromboplastin time(PTT) were measured in 27 patients with KHF who were admitted to Chungnam National University Hospital from Oct. 1986 to Sept. 1988. The results were as follows 1. 19 patients(70.4%) out of 27 patients with KHF revealed petechial hemorrhage on axilla and soft palate. UGI bleeding, epistaxis and gross hematuria were also observed in 2, 2 and 2 patients, respectively. 2. In early phase of KHF, hemoglobin concentration showed normal in 21 patients (77.8%), reduced in 5 patients (18.5%)'and elevated in 1 patient. In late phase of KHF, it showed normal in 16 patients(59.3%) and reduced in 11 patients (40.7%). 3. Reticulocyte percent was significantly lower in early phase than late phase of KHF. 4, In early phase of KHF, peripheral blood leukocyte count was elevated in 23 patients(81.2%). In late phase, it became to normal in most patients. 5. In early phase of KHF, peripheral blood platelet counts was decreased in 24 patients (88.9%). In late phase, it became to normal in most patients. 6. In early phase of KHF, fibrinogen concentration was decreased in 3 (13.6%) out of 22 patients. In late phase it became to normal in all patients. FDP showed increased in 9 (40.9%) out of 23 patients in early phase of KHF and 2 (18.2%) out of 11 patients in late phase of KHF 7. PT showed normal range in all patients of early and late chase of KHF. In early phase, PTT was prolonged in 7 (29.2%) out of 24 patients and it became to normal in late phase of KHF.
