  • Monoclonal antibody(TCM-9) against human thyroid cancers have been studied by screening with human thyroid cancers, normal and benign thyroid tissue, and normal human serum protein. A monoclonal antibody(TCM-9) that is known to have strong specificity for human thyroid cancer but not for Graves' disease, adenoma or normal thyroid does not bind to native or mature human thyroglobulin(Tg). We used to TCM-9 antibody by immunohistochemical staining on 5 follicular cancer, 2 follicular adenoma, 1 follicular neoplasm with suspicious invasion, 2 papillary cancer to ascertain being of help in differentiation between follicular carcinoma and adenoma. Reactivity of TCM-9 was observed in follicular carcinoma and papillary carcinoma but not observed in follicular adenoma. Thus TCM-9 is a novel monoclonal antibody against the thyroid cancer.

  • In this paper, as a basic study for combination of turbo equalizer and 4D-8PSK-TCM(4 Dimensional 8 Phase Shift Keying Trellis Coded Modulation) system, which is recommended for X-band band satellite communication in CCSDS, a system combining 8PSK-TCM system and turbo equalizer has designed and performance evaluation of the system has performed. BER performance of 8PSK and 8PSK-TCM systems has evaluated and analyzed in AWGN, Proakis B and Proakis C channels in detail. As results of simulation, BER performance of 8PSK-TCM system is better than 8PSK system in AWGN environment. Furthermore, it can be confirmed that the system combining the 8PSK-TCM system with the turbo equalizer can further improve the BER performance through iterative equalization in the ISI channel environment. The 8PSK-TCM system combined with the turbo equalizer requires SNR of 5.9 dB for BER performance of $10^{-3}$ with 5 iterative equalization in Proakis B and SNR of 9.1 dB for BER of $10^{-2}$ with 5 iterative equalization in Proakis C.

  • TCM has been used for many environmental impact assessments and many case studies in Korea. TCM was applied to urbvan areas and rolling terrains. But original TCM was developed for rural area, and this model could not reflect the characteristcs of these study sites. This paper analyzed the characteristics of TCM, and modified the algorithm of area source, and modified the vertical wind speed profile exponents and diffusion parameter to make it applicable in urban area. In the process of modification, an important error in area source calculation of original TCM program was found. So that was corrected as follows. $$ Before modification $QC = 0.79788456^*(0.5^*GRID)^**BA/(U(IA, IRUN)^*AA^*BA TCM09310$ After modification $QC = 0.79788456^*(500^*GRID)^**BA/(U(IA, IRUN)^*AA*BA) modified$ $$ Then original TCM and modified TCM-urban mode were compared, and it was found that predicted mean value by original TCM was 7 times higher than observed mean value. But mean value by modified TCM-urban mode was very similar to observed value.

  • This paper describes TCM(trellis coded modulation) schemes using 32VSB signal for digital CATV system. First we design optimum encoder with code rate 4/5 for 32VSB by using one dimenstional signal constellation and obtain 0.75-4.38 dB coding gains over the existing uncoded 16VSB. Second by using two dimensional signal constellation we design TCM encoders with code rate 9/10, which are better in the power efficienty (0.5-2.27 dB) and the transmission rate(12.5%), and we also design TCM encoders which have more coding gains than one dimensional TCM encoders for the larger number of states(more than 8 states).

  • In this paper, system performance of turbo trellis coded modulation (turbo TCM) is presented and analyzed through computer simulations over two typical channels, namely additive white Gaussian noise (AWGN) and Rayleigh fading channels. We use and compare different mapping strategies based on Ungerboeck partitioning (UP), block partitioning (BP), mixed partitioning (MP), Gray partitioning (GP), and Ungerboeck-Gray partitioning (UGP) of the signal constellation of the turbo TCM system. Furthermore, taking 8PSK modulation of turbo TCM as an example, our simulation results show that turbo TCM with UP can obtain better performance than turbo TCM with BP, MP, GP, and UGP in both AWGN and Rayleigh fading channels.

  • In this paper, a burst-error-correcting adaptive decoding in TCM(Trellis Coded Modulation) is presented that combines maximun-likelihood decoding with a burst error detection scheme. The decoder usually operates as a Viterbi decoder and switches to a burst-error-correcting mode whenever error patterns uncorrectable by Viterbi decoder are detected. It is demonstrated that TCM using adaptive decoding method outperforms a traditional TCM on the multi-path fading channels that are busty in nature, which are like the channel environments of mobile communications.

  • According to 2004 health statistics yearbook, cancer ocupies second death reason next to disease of blood circulation system and 1/4 was died because of cancer. There are very many factors to onset cancer, for example the exposure to varius kinds of pollution materials by development of industry, excess intake of harmful food to one's health, spritual stress, as become old age society, increase of attack-rate of geriatric diseases etc, attack-rate of cancer comes to be high gradually. The author had study about to treatment cancer by TCM(traditional chinese medicine) and combining TCM & western medicine, in Guang An Men hospital in Beijing of China from February 2003 to January 2004. TCM papers are 105 and combining TCM & western medicine papers are 280 of total 385 papers. Clinical reserch papers are 166, review articles are 194, animal experimental papers are 25. The papers used development herbal medicine are 42(10.9%), the papers used undevelopment herbal medicineare are 228(59.2%), the papers used senior TCM doctor's therapeutic experience and theory are 17(4.4%), the papers used theory of TCM or theory of combining TCM & western medicine are 71 (18.4%), the papers used acupuncture, qigong, thermotherapy, etc, other methods are 5, the papers used TCM patient's care or dietary treatment are 12 and ststistical papers are 10. Cancer is complicated hard case disease in pathological process. Combining TCM & western medicine treatment system is more efficient than one of TCM or western medicine in diagnosis, treatment, reserch of cancer.

  • The eye of human is a radiation sensitive organ and this organ should be shielded from radiation exposure during brain CT procedures. In the brain CT procedures, bismuth protector using to reduce the radiation exposure dose for eye. But protecting the bismuth always accompanies problem of the image quality reduction including artifact. This study aim is the eye radiation exposure dose and image quality evaluation of the new tube current modulation such as new organ based-tube current modulation, longitudinal-TCM, angular-TCM between shielding scan technique using bismuth and lead glasses. As a result, radiation dose of eye is reduced 25.88% in new OB TCM technique then reference scan technique and SNR new OB TCM is 6.05 higher than bismuth shielding scan technique and lower than reference scan technique. In clinical brain CT, new OB TCM technique will contribute to reduction of radiation dose for eye without decrease of image quality.

  • This paper addresses the design of trTCM (Two Rate Three Color Marker) described in RFC2698. It has proposed for trTCM to be used in Differentiated Service network that provides AF PHB (Assured Forwarding Per Hop Behavior). trTCM is the marker with the metering function, and consists of the token updating function and the marking function. The token updating function uses the dual token bucket. The marking function compares the token values with the length of input packet and then marks the result into IP QoS field (ToS field). In this paper, we design trTCM function and then addresses the scheme to implement it using FPGA technology.

  • The protective effect of Naoxingtong (NXT) on rat cerebral microvascular endothelial cell (rCMEC) was investigated. rCMEC was injured in vitro by incubating for 4 hours at 100% NO in a hypoxia chamber. After treated with NXT-containing serum, the cellular viability rate (90.3%) was significantly elevated when compared with that of control group and the inhibitive rate of lactic dehydrogenase activity (9.2%) was far lower than the control group with dose-dependent effect. The results indicate that NXT can increase viability of rCMEC, and protect cell membrane from injury during hypoxia.
