Thermal conditions are an important environmental factor in maintaining healthy pigs because they affect feed intake, growth efficiency, reproduction and immune responses in pigs. RAVI, a regenerative far-infrared heating system, can effect pig production by emitting an optimal far-infrared wavelength. Far-infrared radiation has been reported to increase microvascular dilation and vascular flow volume. The purpose of this study was to evaluate the immunobiological differences between pigs raised with the RAVI system and the gasoline heater system. Twenty-six-week-old weaned pigs were raised in two rooms that were equipped with a RAVI system or a gasoline heater for 8 weeks. A porcine atrophic rhinitis vaccine was administered after two weeks and transcriptome analysis in whole blood were analyzed at 2-week intervals. Signaling pathway analyses of the RAVI group at 8 weeks showed the activation of pathways related to nitric oxide (NO) production. This suggests that the application of RAVI might induce the production of NO and iNOS, which are important for increasing the immune activity. Similar to the result of microarray, phenotypic changes were also observed at a later period of the experiment. The increase in body weight in the RAVI group was significantly higher than the gasoline heater group at 8 weeks. The antibody titer against the vaccine in the RAVI group was also higher than that the gasoline heater group at 4 weeks and 8 weeks. This evaluation of the use of a far-infrared heating system with pigs will be helpful for applications in the pig farm industry and pig welfare.

2.Three Cases of Planned Complex Suicide
Korean Journal of Legal Medicine 2019;43(4):159-163
Complex suicide refers to a type of suicide that leads to death using two or more methods. We report three cases of unique and rare examples of complex suicide, with the plan of the second and/or third method working simultaneously if the first suicidal attempt had failed. In the first case, the victim used three methods of asphyxia: hanging by a safety belt, plastic bag suffocation, and self-ligature strangulation by stretching rubber bands within the vehicle. In the second case, the victim hanged himself with electrocution by attaching electrical leads to the right side of his head. In the third case, the victim with the intention of drowning jumped 20 m above the water surface on the bridge by tying metal chains to the bridge rail and self-immolation by gasoline. Planned complex suicide involves more successful methods to commit suicide and may conversely be camouflaged as suicide in murder case.

BACKGROUND: Evidence on associations between occupational diesel exhaust and gasoline exposure and colorectal cancer is limited. We aimed to assess the effect of workplace exposure to diesel exhaust and gasoline on the risk of colorectal cancer. METHODS: This caseecontrol study included 181,709 colon cancer and 109,227 rectal cancer cases diagnosed between 1961 and 2005 in Finland, Iceland, Norway, and Sweden. Cases and controls were identified from the Nordic Occupational Cancer Study cohort and matched for country, birth year, and sex. Diesel exhaust and gasoline exposure values were assigned by country-specific job-exposure matrices. Odds ratios and 95% confidence intervals were calculated by using conditional logistic regression models. The results were adjusted for physical strain at work and occupational exposure to benzene, formaldehyde, ionizing radiation, chlorinated hydrocarbons, chromium, and wood dust. RESULTS: Diesel exhaust exposure was associated with a small increase in the risk of rectal cancer (odds ratio 1/4 1.05, 95% confidence interval 1.02–1.08). Gasoline exposure was not associated with colorectal cancer risk. CONCLUSION: This study showed a small risk increase for rectal cancer after workplace diesel exhaust exposure. However, this finding could be due to chance, given the limitations of the study.

The objective of this study was to verify a change in the longitudinal trend of blood lead levels for the Korean population, before and after the regulation of leaded gasoline— which occurred between 1987 and 1993 in Korea. A total of 77 reports on blood lead levels among general Korean population between 1981 and 2014 were selected, and the results were summarized to have the variables of year, number of subjects, the subjects’ range in age, gender, and blood lead concentrations (arithmetic mean). The annual average atmospheric lead levels for four major cities (i.e., Seoul, Busan, Daegu and Gwangju) were collected from the Air Pollution Monitoring Database from 1991, and pilot studies from 1985 to 1990 before the national air quality monitoring system was launched in 1991. Blood lead levels were visualized in a bubble plot in which the size of each bubble represented the sample size of each study, and the annual average concentrations in ambient air were depicted on line graphs. Blood lead levels in the Korean population tended to gradually increase from the early 1980s (approximately 15-20 μg/dL) until 1990-1992 (20-25 μg/dL). Blood lead levels then began to rapidly decrease until 2014 ( < 2 μg/dL). Similar patterns were observed for both adults (≥20 years) and younger children/adolescents. The same longitudinal trend was observed in annual average atmospheric lead concentration, which suggests a significant correlation between air lead concentration and blood lead concentration in the general population. In conclusion, the regulation of leaded gasoline has significantly contributed to the rapid change in blood lead concentrations. And, the regulation of other sources of lead exposure should be considered to further decrease blood lead levels in the Korean population.

Gasoline is a chemical compound of aliphatic and aromatic hydrocarbons, and it easily vaporizes because of its volatile characteristics. Gasoline inhalation may occur accidentally or intentionally in various situations which could result in acute non-lethal or lethal intoxication. Given that gasoline is widely used in everyday life, it is surprising that deaths related to gasoline inhalation rarely occur. We presented a rare case of unexpected death related to gasoline inhalation with the postmortem findings and features.

China's energy supply becomes more serious nowadays and the development of bio-energy becomes a major trend. Large oil companies have superb technology, rich experience and outstanding talent, as well as better sales channels for energy products, which can make full use of their own advantages to achieve the efficient complementary of exist energy and bio-energy. Therefore, large oil companies have the advantages of developing bio-energy. Bio-energy development in China is in the initial stage. There exist some problems such as available land, raw material supply, conversion technologies and policy guarantee, which restrict bio-energy from industrialized development. According to the above key issues, this article proposes suggestions and methods, such as planting energy plant in the marginal barren land to guarantee the supply of bio-energy raw materials, cultivation of professional personnel, building market for bio-energy counting on large oil companies' rich experience and market resources about oil industry, etc, aimed to speed up the industrialized process of bio-energy development in China.

7.Auto-LPG (Liquefied Petroleum Gas) and its health outcomes: A review.
Acta Medica Philippina 2013;47(2):62-65
The use of auto-LPG (Liquefied Petroleum Gas) has spread globally due to its economic and environmental advantages over gasoline and diesel. The growing popularity of auto-LPG in the country has been challenged by reported health complaints from its use instigating alarms among taxi drivers and passengers. This paper aims to review documented health outcomes of auto-LPG among drivers. Health outcomes of auto-LPG are classified to inhalation effects and burns. Auto-LPG is expected to have inhalational effects such as headache, dizziness, dry throat, nausea and dry cough during prolonged exposure caused by leakage from faulty conversions. Fire and explosion causing significant burns were documented in relation to auto-LPG use. Cases of cold burns or frostbite were also reported. Human factors and technical malfunctions causing leakage were implicated on the reported adverse health event. Limited studies on auto-LPG and health outcomes require the development and use of objective assessment of health outcomes and presence of auto-LPG in the driver's environment to make relevant correlations. Regulations governing auto-LPG should be reviewed to formulate strategic interventions to promote health and safety of drivers as well as the passengers.

8.Case of Chemical Pneumonitis and Cellulitis after Suicide Attempt by Arteriovenous Fistula Injection of Gasoline.
Journal of the Korean Society of Emergency Medicine 2011;22(4):370-375
While much is known concerning intoxication by aspiration of volatile hydrocarbon products, knowledge of intravenous injection of these distillates is rare. This article is a review of various complications after intravascular injection of gasoline. We report a rare case of a suicide attempt of by a male who had chronic renal failure with arteriovenous fistula (AVF). The suicide attempt involved injection of gasoline into the AVF site. After the injection, dermal problem and mild dyspnea developed due to pulmonary edema. These symptoms and radiologic finding of pulmonary edema were similar to those caused by the inhalation of gasoline. The characteristic damage following gasoline inhalation is similar to the present case, and occurs when the gasoline gas spreads to the lung alveoli. In this patient, gasoline entered the AVF site, and the patient developed a soft-tissue phlegmon and cellulitis on the forearm. We did an incision and decompression of the wound, and recreated the AVF site. Two weeks later, the wound was clean and the patient was discharged. The major change after injection of gasoline into the AVF site was chemical pneumonitis, wound inflammation, phlegmon, and malfunction of the AVF site.

Life Cycle Assessment (LCA) is the only standardized tool currently used to assess environmental loads of products and processes. The life cycle analysis, as a part of LCA, is a useful and powerful methodology for studying life cycle energy efficiency and life cycle GHG emission. To quantitatively explain the potential of energy saving and greenhouse gas (GHG) emissions reduction of corn stover-based ethanol, we analyzed life cycle energy consumption and GHG emissions of corn stover-based ethanol by the method of life cycle analysis. The processes are dilute acid prehydrolysis and enzymatic hydrolysis. The functional unit was defined as 1 km distance driven by the vehicle. Results indicated: compared with gasoline, the corn stover-based E100 (100% ethanol) and E10 (a blend of 10% ethanol and 90% gasoline by volume) could reduce life cycle fossil energy consumption by 79.63% and 6.25% respectively, as well as GHG emissions by 53.98% and 6.69%; the fossil energy consumed by biomass stage was 68.3% of total fossil energy input, N-fertilizer and diesel were the main factors which contributed 45.78% and 33.26% to biomass stage; electricity production process contributed 42.06% to the net GHG emissions, the improvement of technology might reduce emissions markedly.
