The far-infrared ray (FIR) has been applied to various fields such as medical therapy, kitchen utensils, bath supplies, and so on. The FIR-emitting agent was used to make functional paperboards to have freshness-maintaining ability. The FIR-emitting agent was diluted with different concentrations at 0.5% starch solution, and the FIR-emitting solutions were coated on paperboards, i.e., liner. The more the concentration of the FIR radiating agent increased at 0.5% cationic starch solution, the higher FIR emissivity and emission power of paperboards increased. The corrugated boxes made of paperboards coated by the FIR-radiating agents at over 5% dilution concentration endowed mandarin oranges in the boxes with greater antimicrobial activity than those in boxes made of paperboards coated by the agent at below 5% concentration. In addition, it was ascertained that treatment of the FIR agents rarely affected strength properties of paperboards.

The Sun's ray is composed of Infrared(49%), Visible light(40%) and Ultra violet(11%), however the ray getting to the earth is FIR(Far infrared; 60%), IR(Infrared; 20%), and UV(Ultra Violet; 20%). Human beings has utilized FIR already from time immemorial. Hershel found out Infrared for the first time. in the Industrial Revolution the Infrared and FIR had been begun to use making products. In these days, with contemporary science FIR would be begun to clear up the implication in the human body and organic compound. IR classified by wavelength three parts NlR, MIR, FIR. There is FIR which is radiated from healthy human body the wave length is 8-l4m. The human body is composed of proteins which get easily changed by a thermal factor (about 42 $^{\circ}$C over). FIR with low temperature can deeply penetrate on the human body composed things without troublesomes, since FIR has effectively operated on the human body at low temperature (35-40 $^{\circ}$C). When FlR penetrated on the human body. it would inhibit the abnormal genes and cells expression, and then information of DNA and RNA would be reexpressed for arranging DNA and RNA abnormal state. As FlR's receptors in the body, it could be presumed that N-glycosyl linkage of purine and deoxyribose, RNA splicing process, and Heat shock protein. To take the FIR which was a optimized wavewlength and strength, at first, we induced the characteristic algorithm and the computerized programing. Then we formed that the formular of optimized FIR with physical, mathematical logic and theory. especially, Plank, Kirchhoff, Wien, Stefan-Boltzmann's logic and law. In the long run, the formular was induced with integration mathematical, since we had to know the molecular wavelength. Based on the induced formular as above, we programmed the optimized FlR radiating computerized program. In this research, we designed the eletronic circuit f3r interfacing with human body to diagnosis and treatment with FIR sensor which radiated FIR wavelength optimized.

Wild grapes have been used as traditional medicinal use and alcoholic beverage production in Korea. The objective of this study is to improve antioxidant properties in Sae-muru by far infrared ray (FIR) treatment, with expecting potential benefits of FIR treatment for wild grape products during manufacturing processes. FIR treatment in berries induced increased content of catechin, epicatechin gallate, epigallocatechin gallate, gallic acid, rutin, ellagic acid, and resveratrol, while content of epicatechin and epigallocatechin was decreased. Although FIR treatment resulted either increased or decreased chemical component groups, presenting in HPLC chromatograms, antioxidant activity in Sae-muru extract was significantly increased by the FIR treatment. Our results suggest that FIR treatment should be an efficient process in the production of high content of bioactive molecules in Sae-muru.

This research was conducted to determine the effect of far-infrared ray (FIR) irradiation of grape berries as a potential application for manufacturing grape products with a high amount of antioxidant chemicals. Two grape cultivars, the red grape cv. Campbell Early and the white grape cv. Thompson Seedless, produced increased amounts of crude extracts, in the FIR treatments compared to a non-FIR treatment control with same temperature. However, total phenolic concentrations and antioxidant activity in a 'Campbell Early' increased in the extracts following FIR treatment, whereas those of 'Thompson Seedless' did not increase significantly. High performance liquid chromatography (HPLC) analysis indicated that functional components affecting antioxidant activity were significantly increased in the extract of 'Campbell Early' following FIR treatment. Our results indicate that application of FIR treatment in heat process of grapes increases levels of antioxidative phenolic chemicals and it may help to enhance the availability of antioxidative compounds in various grape food products.

Recent high-resolution infrared space missions have revealed supernova remnants (SNRs) of diverse morphology in far infrared (FIR), often very different from their X-ray appearance. This suggests that the FIR emission from SNRs could be of different origins. For a sample of 20 Galactic SNRs, we examine the correlation between their FIR and X-ray properties and explore the origin of the FIR emission. We find that the SNRs with very different FIR and X-ray morphology have relatively large infrared-to-X-ray (IRX) flux ratios. We argue that the FIR emission in these SNRs is likely mainly from dust grains radiatively-heated by shock radiation. For SNRs with similar IR and X-ray morphology, the FIR emission of which is probably mostly from dust grains collisionally heated by hot plasma, we compare their IRX flux ratios with theoretical ratios from a model incorporating time-dependent dust destruction and non-equilibrium ionization cooling behind SNR shock, and discuss the implications of our result.

원적외선은 자연계의 태양에너지의 한 부분으로 가시광선의 적색영역보다 파장이 월등히 길어서 열작용이 크며, 생체 내 침투력이 강한 파장으로 알려져 있다. 본 연구에서는 육계를 사육하는 과정에서 일정량의 원적외선을 조사하는 방법으로 육계의 건강 증진은 물론, 사육환경의 개선 효과의 가능성을 검정하고자 하였다. 세미브로(Ross ♂ ${\times}$ Hyline ♀) 암수 무감별추 200수를 공시하여 흰색조명, White구(5,000~5,700 K), 흰색조명+원적외선 조사(White+FIR구), 녹색조명, Green구(525~570 nm) 녹색조명+원적외선(Green+FIR구)의 4처리, 처리당 2반복으로 실험을 실시하였다. 전 사육기간 중 증체량과 사료효율은 녹색조명 환경이 백색조명 환경보다 높게 나타나는 경향이 인정되었다. 이러한 증가는 두 조명 모두 원적외선 조사에 의해서 더 증가되는 경향이 인정되었다. 사육장 바닥 깔짚 내 ammonia 및 저급탄화수소의 발생량은 조명의 색깔에 따른 차이는 인정되지 않았지만, 두 조명 모두 원적외선 조사에 의해서 ammonia 및 저급탄화수소의 발생량이 감소하는 경향이 인정되었다. 혈장 내 AST의 농도는 녹색조명 처리구가 백색조명 처리구보다 낮게 나타났으며, 이러한 경향은 두 조명 모두 원적외선의 조사에 의해서 더 감소되어서 백색조명 처리구보다 녹색조명에 원적외선을 조사한 처리구에서 유의하게 낮게 나타났다(P<0.05). 혈액 중 albumin 및 각종 면역 글로블린(LgA, lgG 및 lgM)의 농도는 조명의 차이에 따른 변화는 인정되지 않았지만, 흰색조명, 녹색조명 모두 원적외선 조사에 따라서 증가하는 경향이 나타났다. 결론적으로 육계 사육과정에 원적외선의 조사는 사육환경 개선 및 생리활성물질의 증가에 영향을 미쳐서 생산성을 증가시킬 가능성이 있다고 생각되어진다.

We present preliminary results of far-infrared(FIR) study of the supernova remnant(SNR)s in the Large Magellanic Cloud using the Herschel HERITAGE (HERschel Inventory of The Agents of Galaxy Evolution) data set. HERITAGE provides FIR data covering the entire LMC at 100,160, 250, 350, and 500 um. In order to confirm FIR emission associated with SNRs, we refer to Magellanic Cloud Emission-Line Survey (MCELS) H-alpha & SII data, Spitzer surveying the Agents of a Galaxy's Evolution (SAGE) Multiband Imaging Photometer (MIPS) 24um & 70um data, Chandra Supernova Remnants Catalog, and ATCA 4.8GHz continuum images of Dickel et al. (2005). Among 47 SNRs in the LMC, 7 SNRs show associated FIR emission. We present multi-wavelength view of 5 SNRs; DEM L249, N49, N63A, N132D, and the SNR in N4. N49 and N132D show morphological correlation in FIR and X-ray, suggesting that the FIR emission is from dust grains collisionally heated by X-ray emitting plasma. The FIR emission of N63A resembles H-alpha emission, which implies that the FIR line radiation could be dominant. The FIR images of the rest two objects, DEM L249 and SNR in N4, show no correlation to the other-waveband images.
