In order to examine how growth substances influence to fruit growth and its quality, we cultivated 3 different kinds of melons which grown in hydroponic system into 3 different types of growth substances, such as perlite, perlite/rock wool and rock wool/perlite. In this experiment, “Siroi Kagayaki”, showed no significant difference in fruit weight and its diameter in any of growth substances, but higher in plant height in perlite/rock wool than Perlite. In case of “TS-1806”, there were no significant differences in soluble solids, fruit weight and diameter in all the substances. However, it showed longer in fruit length in rock wool / perlite than that in perlite/ rock wool. In addition, the soluble solids in placenta and flesh were higher in perlite than those in rock wool/perlite.

The purpose of this study was to evaluate the depth of cure using various curing light sources. XL 3000 for halogen light, Apollo 95E for plasma arc light and Easy cure for LED light source were used in this study. To measure the depth of cure, B1 and A3 shade of Composites (Esthet·X, Dentsply, U.S.A.) were used. The 1,2 and 3mm thick specimens were fabricated according to various curing times and light sources. Victor's hardness test was performed after 24hours storage in distilled water. The results were as follows : 1. In all light sources, as the curing times increased the hardness values were decreased(p<0.05). 2. In halogen curing groups, the Victor's hardness was decreased as the depth increase except between 1mm and 2mm. 3. In halogen-10 and 20second curing groups. the Victor's hardness of A3 shade were lower than Bl shade, but not in 40second-curing group. 4. There were significant differences in Victor's hardness between two shades in 2,3mm of Plasma arc and LED light source curing groups(p<0.05). but not in 1mm. 5. In Bl shade, mean 2mm bottom surface hardness value of halogen-40second curing group was 61.46 and it was lower than plasma arc-10second and LED-40second curing group, in A3 shade, 2mm bottom surface hardness value of halogen-40second curing group was 59.70 and it was lower than LED-40second curing group.

Optimal Timing of Percutaneous Coronary Intervention in Patients With Non–ST-Segment Elevation Myocardial Infarction Complicated by Acute Decompensated Heart Failure (from the Korea Acute Myocardial Infarction Registry-National Institutes of Healt

Kim, Min Chul,Jeong, Myung Ho,Sim, Doo Sun,Hong, Young Joon,Kim, Ju Han,Ahn, Youngkeun,Ahn, Tae Hoon,Seung, Ki Bae,Choi, Dong-Joo,Kim, Hyo-Soo,Gwon, Hyeon Cheol,Seong, In Whan,Hwang, Kyung Kuk,Chae, S Elsevier 2018 The American journal of cardiology Vol.121 No.11

<P>The optimal timing of percutaneous coronary intervention (PCI) in patients with non–ST-segment elevation myocardial infarction (NSTEMI), complicated by acute decompensated heart failure (ADHF), is unclear. A total of 1,027 patients with NSTEMI complicated by ADHF who underwent successful PCI were analyzed using a Korean multicenter registry. All patients were divided into 4 groups by the timing of PCI: group 1 (PCI < 2 hour after admission, n = 149), group 2 (2 to 24 hours, n = 577), group 3 (24 to 72 hours, n = 189), and group 4 (≥72 hours, n = 112). We analyzed the incidences of 12-month mortality, nonfatal myocardial infarction (MI), target-vessel revascularization, and rehospitalization because of HF. The prevalence of ADHF in patients with NSTEMI was 15.2% at initial presentation, and in-hospital mortality was higher in group 1 than in the other groups. There were no significant differences in mortality, nonfatal MI, target-vessel revascularization, or rehospitalization for HF during the 12-month follow-up between groups, regardless of initial PCI timing, except for a higher 12-month mortality in patients who received PCI within 24 hours (vs ≥24 hours) (hazard ratio 1.52, 95% confidence interval 1.09 to 2.29, p = 0.046). Early PCI did not reduce adverse clinical outcomes in patients with NSTEMI complicated by ADHF. Delayed PCI after stabilization may be reasonable in such high-risk patients.</P>

The causes of death of pelvic bone fracture are hemorrhage, associated internal organ injuries, sepsis, and multi-organ failure, among which hemorrhage still remains as the leading cause of death. While previous classification for pelvic bone fracture was focused on orthopedic treatment, Pennel & Sutherland suggested a new classification according to the pelvis AP film took in the emergency room. Since this classification supposedly evaluates hemorrhage from pelvic bone fracture, we are reporting on the efficiency of this classification. Out of all the 150 patients admitted to Yong Dong Severance Hospital Emergency Room from 1992, Jan. through 1994, Dec. due to pelvic bone fracture, 18 people with incomplete medical record and X-ray film excluded from the study. The study was done Cohort method and t-test was used. According to the new classification, the unstable fracture had a much more bleeding amount regardless of the type, and type I stable fracture bled more than all the other stable fracture. These were statistically meaningful. Also, there was no differences in the type of fracture when ISS(Injury Severity Scale), GCS(Glasgow Coma Scale), and associated injury were compared. In conclusion, previous classification was done according to orthopedic treatment and this classification could be done only after pelvis X-ray series and pelvic bone CT was performed. Therefore much more time is consumed, more stress is put upon the patient and no comparisons can be made in performing emergency care. On the other hand, modified Pennel &-Sutherl`s classification can be simply classified in the emergency room by taking pelvis AP film only and the bleeding amount can be measured according to the type. Therefore, this classification can be helpful in performing emergency care.

In this study the antimicrobial spectrum and sensitivity of a liquid formulation of enrofloxacin against the major six pathogenic bacteria isolated from the diseased poultry in Korea were evaluated in comparison with ciprfloxacin (CFX), gentamicin (GM) and penicillin (PC). A liquid form of enrofloxacin, a test material and ciprofloxacin showed at least 83% antibacterial activity against all of six test pathogenic microorganisms at the fixed concentration of 10 ㎍/㎖. Gentamicin and penicillin revealed much lower antibacterial activity at the same condition. We evaluated the liquid form of enrofloxacin as having widespread antibacterial spectrum against poultry infections. The liquid form of enrofloxacin showed potent antibacterial activity, with the MIC range being 0.12∼2 ㎍/㎖ against Gram positives, 0.06∼2 ㎍/㎖ against Gram negatives and 0.5∼2 ㎍/㎖ against Mycoplasma spp. These values were equivalent to or somewhat higher than those of ciprofloxacin, but much lower than those of gentamicn and penicillin. This new liquid form of enrofloxacin would find its way in application of mixing with drinking water for the prevention and treatment of diverse infections in chickens.

In spite of other communication service such as e-mail as growing Internet, the mail is fast growing. In process of mail service, the delivery sorting process is a bottleneck due to its time assuming work. Delivery Sorting System (DSS) sorts the mail by delivering order in high speed real-time process. The existing DSS is based on QNX with own network. QNX is real time OS based on POSIX. QNX RTOS is robust from tiny embedded device but it is expensive and is difficult to maintain. The suggested system based on Linux / Embedded is Flexible and economy due to open source.

Purpose of this research is estimating polymerization depth of different source of light. XL 3000 for halogen light, Apollo 95E for plasma arc light and Easy cure for LED light source were used in this study. Different shade (B1 & A3) resin composites (Esthet-X, Dentsply, U.S.A.) were used to measure depth of cure. 1, 2, and 3 mm thick samples were light cured for three seconds, six seconds or 10 seconds with Apollo 95E and they were light cured with XL-3000 and Easy cure for 10 seconds, 20 seconds, or 40 seconds. Vicker's hardness test carried out after store samples for 24 hours in distilled water. Results were as following. 1. Curing time increases from all source of lights. curing depth increased(p<0.05). 2. Depth (that except 1mm group and 2mm group which lighten to halogen source of light) deepens in all groups, Vicker's hardness decreased(p<0.05). 3. Vicker's hardness of A3 shade composite was lower in all depths more than B1 shade composites in group that do polymerization for 10 seconds and 20 seconds using halogen source of light(p<0.05), but group that do polymerization for 40 seconds did not show difference(p>0.05). 4. Groups that do polymerization using Plasma arc and LED source of light did not show Vicker's hardness difference according to color at surface and 1mm depth(p>0.05), but showed difference according to color at 2mm and 3mm depth(p<0.05). The results showed that Apollo 95E need more polymerization times than manufacturer's recommendation (3 seconds), and Easy cure need polymerization time of XL-3000 at least.

Aims: Management of multidrug resistant (MDR) chronic hepatitis B (CHB) is still challenging. Although current guidelines recommend tenofovir (TDF) or TDF+entecavir (ETV) for MDR CHB, real-life data comparing various combinations based TDF and TDF+ETV are lacking. Herein, we report a multicenter cohort study for the evaluation of TDF-based therapy for MDR CHB. Methods: The inclusion criteria were CHB patients with resistance to more than 2 nucleos(t)ide analogues and hepatitis B virus (HBV) DNA level over 200 IU/mL (or 1000 copies/mL). Patients with decompensated cirrhosis or hepatocellular carcinoma were excluded. Primary end point was virologic response (VR) defined by undetectable HBV DNA at month 12. Secondary endpoints were VR at month 24 and 36. Results: A total of 230 patients were enrolled. Mean age of patients were 49 years and 77.4 % were male. Mean baseline HBV DNA level was 4.1 log IU/mL. 78 patients (34.0%) were resistant to L-nucleoside analogues (L-NA) and ADV. 75 patients (32.6%) were resistant to L-NA and ETV, and 67 patients (29.2%) were resistant to both ADV and ETV in addition to L-NA. Initial treatments for MDR CHB were TDF+ETV 1 mg (165, 71.7 %), TDF+ETV 0.5 mg (7, 3.0 %), TDF+lamivudine (9, 3.9 %), TDF+telbivudine (1, 0.4 %), and TDF monotherapy (34, 14.8 %). Virologic response rates of the whole cohort at month 12, month 24, and month 36 were 75.3%, 83.4 %, and 88.2 %, respectively. When we compared the virologic response rate in-between TDF+ETV 1 mg group, other combination group, and TDF monotherapy group, there was no difference among the groups (74.0 %, 83.3 %, and 76.9 %, respectively, P = 0.770) at month 12. TDF monotherapy was not inferior to any combination therapies. Result of data analysis at month 24 (82.7 %, 83.3 %, and 88.9 %, respectively, P = 0.920) and month 36 (89.0 %, 88.9 %, and 87.5 %, respectively, P = 0.592) showed the same trends. Conclusions: TDF based therapy was effective for the treatment of MDR CHB. The efficacy of TDF monotherapy did not differ from the TDF based combination therapies.
