Purpose: The aim of this study was to synthesize the best available evidence for active warming interventions during cesarean section. Methods: A database search was done for randomized controlled trials utilizing active warming interventions. Maternal temperature, shivering and neonatal temperature were evaluated as outcome variables. Data were analyzed using Cochrane Review Manager software Version 5.3. Results: Thirteen studies including 1306 patients were reviewed. The degree of lowering of maternal temperature decreased in the warmed fluids (MD 0.51; p=.004) and warming mattress interventions (MD 0.22; p<.001) compared with control groups. Incidence of shivering was also lower in the active warming group (OR 0.55; p=.003). There was no statistically significant difference in maternal temperature with a forced air warming intervention (MD 0.64; p=.15) or in neonatal temperature (MD 0.12; p=.26). Conclusion: Findings show that with warmed fluids and warming mattresses applied during cesarean sections maternal temperature decline was reduced and also the incidence of shivering declined, but no significant effect was observed for forced air warming interventions. These findings provide a basis for developing a warming guideline for women having a cesarean section and will help to improve the quality of care for cesarean section patients.

The purpose of this study is to investigate empirical evidences of productivity of life insurance institutions in Malaysia. Therefore, this study attempts to explore the productivity of the life insurance institutions in Malaysia. The overall findings show that the total factor productivity (TFP) has progressed by 2.5% per year during the study period from 2012 to 2016 in the Malaysian insurance industry. However, TFP change has declined from 2012 to 2015 and observed a negative growth in 2015-16 (3.3%). The highest productivity progress was documented during 2012-13 at a rate of 11.7% while the minimum productivity progress was during 2014-15 (only 0.2%). The results also indicate that the decomposition of TFP found that overall progress could mainly be attributed to technological change (TC). However, technical efficiency change (TEC) and pure technical efficiency change (PTE) have negative impact on TFP. The findings also show that most of the insurance companies have a steady growth. Therefore, this study will contribute new insights for the policy makers and insurance institutions to take appropriate steps in developing relevant policies for increasing productivity of insurance institutions in Malaysia.

In this study, the quality characteristics of spray dried powders from unripe fig extract were investigated. The protease activities of unripe fig and peeled unripe fig extract were 0.11 unit/mL and 0.28 unit/mL, respectively. The spray dried powder of unripe fig extracts was analzed using different maltodextrin ratios (F-MD 5, 5% maltodextrin; F-MD 10, 10% maltodextrin; and F-MD 20, 20% maltodextrin). The spray-dried powder showed the highest protease activity with F-MD 10 (0.84 unit/g). The moisture content and L value of the spray-dried powder were higher than those of the freeze-dried powder. The particle diameter of the freeze-dried powder ($209.67{\mu}m$) was higher than that of the spray-dried powders ($22.18{\sim}37.33{\mu}m$). The water absorption index ranged from 0.18 to 0.40, while the water solubility index ranged from 94.40% to 98.80%. In the in vitro digestion study, spray-dried powders of the unripe fig showed a protease survival range of 16.47%~24.80%. In conclusion, it is considered appropriate to use the spray-dried powder (F-MD 10) of unripe fig as a meat tenderizer for processing food.

Three strains of bacteria utilizing salicylate, KU801(pKU5, pKU8), KU803(pKU6, pKU9), and KU806(pKU7, pKU10), were selected from the isolates and identified as Pseudomonas putida. By agarose gel electrophoresis, it was found that the strains had two plasmids each. All three strains were resistant to antibiotics such as ampicillin, tetracyclin, and chloramphenicol, and did not utilize other aromatic and aliphatic hydrocarbons examined except salicylate. The plasmids (pKU5, pKU6, and pKU7) of larger molecular weight were cured by treatment with mitomycin C and frequencies of curing were 0.4%, 1.67%, and 0.75%, respectively. Cured strains did not degrade salicylate and still had antibiotic resistances, which were identical with wild strains. The genes for salicylate degradation were proved to be enclded on thier plasmids. The molecular weights of pKU5 and pKU6 were estimated as 103.5Md, and that of pKU 7 as 101 Md. The new SAL plasmids, pKU5, pKU6, and pKU7 were transferred to P. putida and P. aeruginosa, but not to E. coli.

PURPOSE: This study aimed to compare the electromyography (EMG) activity for the middle deltoid (MD) and upper trapezius (UT) muscles in various shoulder abduction angles in patients with adhesive capsulitis (AC). METHODS: A total of 15 subjects participated in the study: 6 without AC (control group) and 9 with AC (AC group). The muscle activities of the UT and MD were measured using EMG during maximal static shoulder abductions in both groups. Each subject performed three repetitions of horizontal abduction at $0^{\circ}$, $30^{\circ}$, $60^{\circ}$, and $90^{\circ}$ of the shoulder abduction angle in a sitting position. The measurement data from the middle 3-seconds of the 5-second periods were used. The mean value of three separate sets of measurements was used in the data analysis. For each muscle, independent t-tests were performed to determine group differences. A measured repeated-measures ANOVA was performed using Bonferroni's post-hoc test. RESULTS: The muscle activity of the UT was significantly greater in the AC group; than in the control group (p<.05). The muscle activity of the MD was significantly lower in the AC group; than in the control group (p<.05). The greatest level of muscle activity for both the MD and UT was demonstrated at the $0-60^{\circ}$ and $0-90^{\circ}$ of shoulder abduction angles in the AC group. CONCLUSION: These findings showed that low muscle activation of the MD may contribute to hyperactivity of the UT during shoulder abduction in AC patients.

Objectives This study is to review the effectiveness of exercise after lung cancer surgery. Methods Relevant randomized controlled trials (RCTs) were searched in PubMed database. The systematic review was conducted through flow diagram. The risk of biases were assessed through the Cochrane guideline. Characteristics and outcomes were extracted from each study. Meta-analyses of forced expiratory volume in one second (FEV1), 6-minute walk test (6MWT), quality of life (QoL), pulmonary complications were conducted. Results 14 RCTs were selected. In meta-analysis, exercise improved FEV1 (mean difference [MD] 0.14; 95% confidence interval [CI] 0.04 to 0.25; p=0.009; I2=55%) and mean change of FEV1 (MD 0.11; 95% CI 0.02 to 0.20; p=0.02; I2=0%). Exercise increased the distance of 6MWT, but there was considerable heterogeneity (MD 45; 95% CI 21.16 to 68.83; p=0.0002, I2=89%). There was no differences in QoL scores by 2 questionnaires (European Organisation for Research and Treatment of Cancer quality of life questionnaire, short form-36). Exercise reduced the duration of hospital stay (MD -3.32; 95% CI -5.27 to -1.36; I2=0%; 2 studies) but not duration of chest tube intubation (MD -1.37; 95% CI -2.81 to 0.06; I2=0%) and incidence of pulmonary complications (pooled risk ratio 0.54; 95% CI 0.23 to 1.30; I2=0%). Conclusions Exercise might reduce the duration of hospital stay after lung surgery. There was not enough evidence to prove improvement of lung function, aerobic capacity, muscle strength, QoL, and decline of pulmonary complications. Low-quality risk of bias, different units or estimation of outcome, different exercise type and duration, heterogeneity among studies make the evidence of effectiveness weak. Future researches are required to redeem these defects.

An isolate of the indigenous fungus Pythium myriotylum was isolated from Monochoria vaginalis in Yusung, Korea in year 2000 and evaluated potential as a biocontrol agent in laboratory and greenhouse. P. myriotylum MD2 grew in a wide range of temperature regimes and the optimal growth temperature was $35^{\circ}C$. The fungus was highly pathogenic to Monochoria vaginalis at 30 to $35^{\circ}C$. Several weeds such as Rotala, indica, Lindernia procumbens, Ludwigia prostrata, Cyperus difformis, Scirpus juncoides, Aneilema keisak were also susceptible to the fungus, but Echinochloa crus-galli was not. The fungus affected the growth of rice seed germinated, but not to rice seedlings of 1- to 3-leaf stage. A total of 12 rice cultivars (3- to 4-leaf stage) tested showed no disease symptoms when inoculated with the fungus. Eleven crops, including Chinese cabbage, corn, soybean except wheat were immune to the infection of the fungi. These data suggest that P. myriotylum MD2 has a potential as a mycoherbicide to control weeds in paddy fields.

Purpose : Lung cancer induces a decrease in physical activity and a deterioration of respiratory ability. Exercise is an effective treatment to reduce side effects of anti-cancer treatments, also influence the survival and successful rehabilitation in lung cancer patients. However, there is insufficient evidence to show which period is the most effective to apply exercise for lung cancer patients. Therefore, this study was conducted to evaluate the efficacy of exercise-based interventions before and after surgery. Methods : Clinical trials (CTs) and randomized controlled trials (RCTs) reported in PubMed database were investigated. The trials investigated in this study were published for 10 years before August 20, 2022. The risk of bias was judged according to the Cochrane guideline. The materials included in this meta-analysis were 6-minute walk test (6MWT), pulmonary function, and quality of life (QOL). Results : 1 CT and 9 RCTs were selected in current study. In the meta-analysis, exercise increased 6MWT in preoperation (mean difference [MD] 29.49; 95 % confidence interval [CI] .99 to 57.99; p=.04; I²=0 %), 3 months postoperation (MD 54.97; 95 % CI 31.85 to 78.09; p<.001; I²=45 %) and 6 months postoperation (MD 85.59; 95 % CI 45.06 to 126.12; p<.001; I²=47 %). Exercise, also enhanced the lung function such as FEV₁/FVC (%) in postoperation (MD 7.64; 95 % CI 6.26 to 9.02; p<.001; I²=19 %). Additionally, exercise improved QOL, such as preoperative EORTC-QLQ-C30-LC13 in mental function (MD 3.21; 95 % CI .64 to 5.79; p=.01; I²=0 %) and postoperative SF-36 in mental component summary (MD 9.24; 95 % CI 4.94 to 13.54; p<.001; I²=0%). Conclusion : These results indicate that exercise-based intervention can elevate the ability to exercise and the mental componentof QOL within 3 months.

To calculate and predict soil carbon budget and cycle, it is important to understand the complex interrelationships involved in soil respiration rate (Rs). We attempted to reveal relationships between Rs and key environmental factors, such as soil temperature, using a laboratory incubation method. Soil samples were collected from mature deciduous (MD), mature coniferous (MC), immature deciduous (ID), and immature coniferous (IC) forests. Prior to measure, soils were pre-incubated for 3 days at $25^{\circ}C$ and 60% of maximum water holding capacity (WHC). Samples of gasses were collected with 0, 2, and 4 h interval after the beginning of the measurement at soil temperatures of 5, 15, 25, and $35^{\circ}C$ (at 60% WHC). Air samples were collected using a syringe attached to the cap of closed bottles that contained the soil samples. The $CO_2$ concentration of each gas sample was measured by gas chromatography. Rs was strongly correlated with soil temperature (r, 0.93 to 0.96; P < 0.001). For MD, MC, ID, and IC soils taken from 0-5 cm below the surface, exponential functions explained 90%, 82%, 92%, and 86% of the respective data plots. The temperature and Rs data for soil taken from 5-10 cm beneath the surface at MD, MC, ID, and IC sites also closely fit exponential functions, with 83%, 95%, 87%, and 89% of the data points, respectively, fitting an exponential curve. The soil organic content in mature forests was significantly higher than in soils from immature forests (P < 0.001 at 0-5 cm and P < 0.005 at 5-10 cm) and surface layer (P = 0.04 at 0-5 cm and P = 0.12). High soil organic matter content is clearly associated with high Rs, especially in the surface layer. We determined that the incubation method used in this study have the possibility for comprehending complex characteristic of Rs.
