기업들은 온실가스 배출권거래제를 대비하여 철저한 준비가 필요하다. 에너지 온실가스 경영을 적극 도입하여야 하며 사업장내의 감축이행에 소요되는 한계비용과 배출권 시장 가격 등을 고려한 다양한 감축 옵션을 검토하여 기업경쟁력 저하를 방지하고, 자사의 강점을 살려 기후변화 시대에 맞는 비즈니스모델 도출을 위한 준비에 힘써야 할 것이다.

Bone density measurement use of diagnosis of osteoporosis and it is an important indicator for treatment as well as prevention. But errors in degree of precision of BMD can be occurred by status of patient, bone densitometer and radiological technologist. Therefore the author evaluated that how BMD changes according to the condition of the patient. As Lumbar region, which could lead to substantial effects on bone density by diverse factors such as the water, food, intentional bowels. We recognized a change of bone mineral density in accordance with the height of the water tank and in the presence or absence of the gas using the Aluminum Spine Phantom. We also figured out the influence of bone mineral density by increasing the water and food into a target on the volunteers. Measured bone mineral density through Aluminum Spine Phantom had statistically significant difference accordance with increasing the height of water tank(p=0.026). There was no significant difference in BMD according to the existence of the bowl gas(p=0.587). There was no significant difference in a study of six people targeted volunteers in the presence or absence of the food(p=0.812). And also there was no significant difference according to the existence of water(p=0.618). If it is not difficult to recognize the surround of bone in measuring BMD of lumbar bone, it is not the factor which has the great effect on bone mineral density whether the test is after endoscopic examination of large intestine and patient's fast or not.

스트레스, 불균형한 식사습관 등으로 복부는 늘 피곤하다. 피곤한 복부를 요가로 풀어보는 것은 어떨까. 요가는 복식호흡으로 복부운동에 효과적이며 복부기관을 자극하고 장내 가스제거에 탁월하다. 또한, 혈액순환을 원활하게 하며 빈혈에 도움이 된다.

본 논문의 목적은 공기 유동장내에 가스분류의 거동을 조사하고 실용 가스 기관의 설계시에 필요한 기초적 데이타를 제공하고자 하는데 있다.본 연구와 관련 된 후래의 연구를 보면 자문등은 열선농도프로브를 사용하여 정상분류중의 농도측정을 행하였고, 분류내의 내부구조를 상세히 조사하였다. 특히, 종래에는 일정하게 보였 던 분류코아 부의 농도변동값의 경향을 구체적으로 나타내었다.

According to the "Framework Act on Low Carbon, Green Growth", publication of annual national greenhouse gas (GHG) inventory report is mandatory. This annual GHG inventory report is used as basal data for GHG mitigation strategies. In the livestock sector, GHG emission trends from year 1990 to 2013 were estimated based on the 1996 IPCC guidelines with the Tier 1 methodology. GHG emissions from the livestock sector in 2013 were 9.9 million tons $CO_2-eq$., where emissions from enteric fermentation were 4.4 million tons $CO_2-eq$, increased by 47.4% over 1990 mainly due to the increase in non-dairy cattle population. On the other hand, GHG emissions from livestock manure in 2013 were 5.5 million tons $CO_2-eq$, increased by 75.5% over 1990 mainly due to the increase in non-dairy cattle, swine and poultry populations. Additional research is required to develop country-specific emission factors to estimate GHG emissions precisely from livestock in South Korea.

현재 막대한 기초투자비와 대규모의 고가장비들로 이루어진 가스시설물 및 관련 산업분야는 풍부한 경험과 깊이 있는 공학적 지식을 바탕으로 코드, 가이드라인, 체크리스트, 표준규격 등의 관리체계를 통해 사업장내에서 상당한 수준의 안전을 보증하고 있다. 하지만 여전히 관련된 사고의 개연성은 상존하고 있으며 인명 및 재산피해를 수반한 사고도 지속적으로 발생하고 있다. (중략)

This study was conducted to investigate the effects of different feeding level of TDN (Total Digestible Nutrients) on the generation of main greenhouse gases such as carbon dioxide and methane in Hanwoo cows. The diet TDN (kg) adjusted to achieve ADG of 0 g/day (Control), 200 g/day (T1), and 400 g/day (T2) of the maintenance level TMR (Total Mixed Ration) delivered twice a day at 08:30 and 17:30. Cow are housed in a respiration chamber and the environmental temperature was maintained at $20^{\circ}C$. The gases were measured for 24 hours using the multi-detector instrument Mamos-300. The analyzed methane emissions of T1 and T2 were 33.5% and 69.6% higher than control, respectively, and the carbon dioxide emissions were 21.1% and 40.6% higher than control. Also, the hourly pattern of carbon dioxide and methane production were showed very similar emission. Gas production showed peak after 1 hour of feeding and this gap was wider in the afternoon than in the morning hours. It is clearly conducted that $CO_2$ and $CH_4$ emissions were different by limited intake levels of feed.

지난 3월 부주의와 방심에서 비롯된 남대문시장 화재를 두고 일부에서는 날벼락을 맞았다고 한다. 소형부탄가스통 8천여개가 연쇄적으로 폭발하면서 인근의 상가에 인화되어 순식간에 상가전체가 잿더미로 변해버린 남대문시장내 고려상가. 악몽과도 같은 그 순간을 잘 극복하고 한창 복구작업에 여념이 없는 현장을 찾았다.

To identify the effect of landfill waste for groundwater and unsaturated air environment, soil gas survey and hydrogeochemical study were executed. The geology of the study area is granite and aquifer is mainly composed of sandy soil. The results of spatial distribution from soil gas showed the boundary of buried waste and processes and degree of waste decomposition. Groundwater contamination by leachate from landfill is controlled by groundwater flow attributed by the original topography and liner.
