The mass measurement of neutron stars or black holes is of fundamental importance in our understanding of the evolution of massive stars and core-collapse supernova explosions as well as some exotic physics of the extreme conditions. Despite the importance, however, it's very difficult to measure mass of these objects directly. One way to do this, if they are in binary systems, to measure their binary motions (i.e., Doppler shifts) which can give us direct information on their mass. Recently many new highly-obscured massive X-ray binaries have been discovered by new hard X-ray satellites such as INTEGRAL and NuSTAR. The new highly-obscured massive X-ray binaries are faint in the optical, but bright in the infrared with many emission lines. Based on the near-infrared spectroscopy, one can first understand the nature of stellar companions to the compact objects, determining its spectral types and luminosity classes as well as mass losses and conditions of (potential) circumstellar material. Next, spectroscopic monitoring of these objects can be used to estimate the mass of compact objects via measuring the Doppler shifts of the lines. For the former, broad-band spectroscopy is essential; for the latter, high-resolution spectroscopy is critical. Therefore, IGRINS appears to be an ideal instrument to study them. An IGRINS survey of these new highly-obscured massive X-ray binaries can give us a rare opportunity to carry out population analyses for understanding the evolution of massive binary systems and formation of compact objects and their mass ranges. In this talk, we will present a sample near-infrared high resolution spectra of HMXB, IGR J19140+0951 and discuss about its spectral feature. These spectra are obtained on 13th July, 2014 from IGRINS commissioning run at McDonald 2.7m telescope. And at final, we will introduce the upgrade plan of IGRINS Operation Software (IGOS), to gather the input from IGRINS observer.

Angelicae gigantis radix is the root of the perennial plant, which belongs to the family Umbelliferae. However, this herbal drug is represented quite different chemical components according to its different genus name, though other herbal drugs (i.e. Leonuri Herba, Xanthii Fructus and so on) show similar constituents on the same name. The root of Angelica gigas containing the coumarin compounds is commonly used in Korea, while Angelica sinensis and Angelica acutiloba including phthalide compounds are used in China and Japan, respectively as Angelicae gigantis radix. In this paper, a nearinfrared spectroscopic method was developed to determine genus name of Angelica spp., especially A. gigas and A. sinensis which are commonly misused in herbal markets. X-ray fluorescence spectrometry and electronic nose have been also applied as nondestructive methods to discriminate A. gigas from A. sinensis according to their specific properties.

Most of the electromagnetic agents used in physical therapy rely for their effects on tissue heating and photoreaction of the body. Infrared and untraviolet light on the other hand, owns its place in medicine because it produces direct photochemial reaction when it interacts with the body. This study was carried out to investigate and review for photoreaction of the akin. The results were an follows. 1. The effects of the infrared are heat production, increasing metabolism, increasing circulation, vasodilatation and pigmentation. 2. Directed photoreactions are divided into acute reaction and chronic reaction, and the acute reaction makes pigmentation from $290\~320nm$ of ultraviolet ray. 3. Ultraviolet ray formated pigmentations, which are melanoblasts excited from ultraviolet ray and received chemical stimulation, that make melanin granule. 4. If exposured with long duration, at ultraviolet ray, it makes skin thickening and epithelioma. 5. Indirected photoreaction is made by existenced hypersensitivity of photoreaction or lack of photodefence structure. 6. The phototoxic reactions are synthesized by chemical reaction of excitement from ultraviolet ray also this time analysis, synthesis and polymerization from energy of a circumferenced substance. 7. Sunscreen substances are P-amino benzoic acid and oxidate titan.

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.

편광 근적외선 조사가 실험적 통증역치에 영향을 미치는지를 규명하기 위해서 건강한 성인의 합곡혈에 여러 단계의 출력량으로 편광 근적외선을 30초간 조사하고 시간 경과에 따라 실험적 통증역치를 측정하여 분석하였다. 실험 결과 출력량 0 %인 대조군과 10 % 및 20 %의 출력량에서는 실험적 통증역치의 유의한 변화가 없었다. 그러나 출력량 40 %군의 실험적 통증역치는 편광 근적외선 조사전 $3.85{\pm}0.51mA$에서 조사 직후 $4.77{\pm}0.87mA$, 조사 후 30분 $5.57{\pm}0.98mA$, 조사 후 1시간 $5.68{\pm}1.06mA$, 조사 후 2시간 $5.34{\pm}0.96mA$로 증가되었고, 출력량 80 %군에서도 실험적 통증역치가 조사전 $3.87{\pm}0.92mA$에서 조사 직후 $4.45{\pm}0.62mA$, 조사 후 30분 $4.91{\pm}0.51mA$, 조사 후 1시간 $4.93{\pm}0.62mA$, 조사 후 2시간 $5.55{\pm}1.11mA$로 증가하였다. 실험적 통증역치는 편광 근적외선 조사 직후부터 2시간까지 유의하게 증가하였다. 40 % 출력량과 80 % 출력량의 실험적 통증역치는 유의한 차이가 없었고, 출력량과 시간의 상호작용효과는 없었다. 건강인의 실험적 통증역치를 대상으로 한 본 연구 결과를 통증이 있는 환자에게 직접 적용하기는 어렵다고 생각하며 앞으로 환자를 대상으로한 연구가 수행되기를 기대한다.

The infusion of fluid and blood is necessary in the ward, operating room, recovery room, neonatal room, etc. for nutrition and blood supply to the patient, but air bubbles generated during infusion of fluid and blood circulate along the artery or vein. Serious illnesses occur and there is also a risk of death. In this paper, we propose a medical bubble detection system, a bubble detection system, a bubble detection alarm system, and a communication method in order to develop a safer fluid and blood injection system in the existing system, which is detected by a medical staff monitoring system or an ultrasonic bubble detection sensor In this study, infrared rays are transmitted to a tube through a tube for injecting fluid or blood into a patient, infrared rays transmitted by an infrared ray emitting section are received, and the amount of light is measured in real time. Based on the data, we study how to detect and analyze the presence of bubbles in fluid and blood.

The Sun's ray is composed of Infared(49%), Visible light(40%) and Ultra violet(11%), however the ray getting to the earth is FIR(60%). IR(20%), and UV(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 FI R had been begun to use making products. In asia. also, asian already has made use of FIR to treat the body, product things and make warm the house in the winter, as it had been called Wull therapy, fermentation. and On-Dol system. In these days, with contemporary science FIR would be begun to clear up the implication in the human body and organic compounds. IR classified by wavelength three parts NIR, MIR, FIR. There is FIR which is radiated from healthy human body the wave length is 8-14 m. It is difficult to standardized the wavelength of IR, since each related associations have a different opinion, so we suggested ideal IR wavelength and biological, phsiotherapical, medical FIR wavelength.
