The part-of-speech determination is necessary for resolving the part-of-speech ambiguity in English-Korean machine translation. The part-of-speech ambiguity causes high parsing complexity and makes the accurate translation difficult. In order to solve the problem, the resolution of the part-of-speech ambiguity must be performed after the lexical analysis and before the parsing. This paper proposes the CatAmRes model, which resolves the part-of-speech ambiguity, and compares the performance with that of other part-of-speech tagging methods. CatAmRes model determines the part-of-speech using the probability distribution from Bayesian network training and the statistical information, which are based on the Penn Treebank corpus. The proposed CatAmRes model consists of Calculator and POSDeterminer. Calculator calculates the degree of appropriateness of the partof-speech, and POSDeterminer determines the part-of-speech of the word based on the calculated values. In the experiment, we measure the performance using sentences from WSJ, Brown, IBM corpus.

Among a number of factors related to the effect of acupuncture and moxibustion treatment, prescriptions do important work. Traditional eastern doctors also placed emphasis on prescriptions of acupuncture and moxibustion, and a lot of experiences have been accumulated. The method forms prescriptions of Sa-am acupuncture therapy pivots on five transport points. Studies show prescriptions are made on the basis of the theory of 'Wang Xiang Xiu Qiu Si'(旺相休囚死) used engendering and restraining of five phases, and it is considered the principle of transformed prescriptions through this theory. Because there is still no study analyzing prescriptions of Sa-am acupuncture by existing principles, we report opinion about Combination principle of points in them. 1. We studied history of acupuncture and moxibustion, development and kinds of points' Combination principle. 2. Around Combination principles of points in Classic of Difficult Issues and Internal Classic, we analyzed and compared between Combination principles of points in Sa-am acupuncture therapy and them in Korea and overall acupuncture methods. 1. There were many Combination principles of acupunture point combination in Classic of Difficult Issues, Internal Classic and Korea acupuncture methods. For example, Point combination of the same meridian, Point combination of the different meridian, Exterior-Interior point combination, Point combination of the same name meridian, Point combination of the multiple meridian, Point combination of Adjacent and Distant points, Left-Right point combination, Anterior-Posterior point combination, Superior-Inferior point combination, Brook point and Stream point combination, Triple energizer point combination, Eight meeting point combination, Five transport point combination, Source-Connecting point combination, Alram point and Transport point combination, Mother-Sun meridian combination, Empirical point combination, Important point combination, Point combination according to syndrome. 2. Existing Combination principles of points in prescriptions of Sa-am acupuncture therapy included every rule. 3. They could be evidences that prescriptions of Sa-am acupuncture therapy are forms inheriting and developing acupuncture and moxibustion treatments.

Objectives : This study is aimed to search for the effective application of the Sa-Am acupuncture(舍岩鍼法) for the treatment of diarrhea. Methods : The classification and the treatment for diarrhea in ${\ll}$Sa-Am-Do-In-Chim-Gu-Yo-Kyul(舍岩道人鍼灸要訣)${\gg}$ was compared with those of ${\ll}$Dong-Eui-Bo-Kham(東醫寶鑑)${\gg}$ and ${\ll}$Chim-Gu-Dae-Sung(鍼灸大成)${\gg}$ Results & Conclusions : In ${\ll}$Dong-Eui-Bo-Kham(東醫寶鑑)${\gg}$, diarrhrea was classified into 20 classes and mainly treated with herbal medicine and additionally with acupuncture treatment. Ashi (nearby) points in lower abdomen and sacral region were often used as well as the points on Spleen meridian(SP) and Stomach meridian(ST) to treat diarrhea in ${\ll}$Chim-Gu-Dae-Sung(鍼灸大成)${\gg}$ According to ${\ll}$Sa-Am-Do-In-Chim-Gu-Yo-Kyul(舍岩道人鍼灸要訣)${\gg}$, Diarrhrea was classified into 6 classes; wet diarrhrea (濡泄; kidney damage), abrupt diarrhrea (暴泄; spleen damage), damp diarrhrea (濕泄; stomach damage), fire diarrhrea (火泄; heart dryness), ki(qi) diarrhrea (氣泄; lung damage) and cold diarrhrea (冷泄; liver damage). Sa-Am acupuncture seems to be applied on the basis of more precise diagnoses of organs and meridians and provide with more fundamental treatments in comparison with classical acupuncture.

A novel adaptive phase calibration method is proposed for nonlinear amplifiers. Based on the adaptive process of simple phase vector calculations, the AM/PM distortion can be significantly reduced for various input power. The performance of the proposed method is evaluated for up to 80 % improvements in AM/PM distortions, compared with the distortion of a conventional amplifier. Moreover, by means of an additional envelope-compensation technique, the improvement of the adjacent channel power ratio (ACPR) is presented.

PURPOSE. The aim of the present randomized controlled study was to compare prefabricated all-ceramic, anatomically shaped healing abutments followed by all-ceramic abutments and all-ceramic crowns and prefabricated standard-shaped (round-diameter) titanium healing abutments followed by final titanium abutments restored with porcelain-fused-to-metal (PFM) implant crowns in the premolar and molar regions. MATERIALS AND METHODS. Forty-two patients received single implants restored either by all-ceramic restorations (test group, healing abutment, final abutment, and crown all made of zirconia) or conventional titanium-based restorations. Immediately after prosthetic incorporation and after 12 months of loading, implant survival, technical complications, bone loss, sulcus fluid flow rate (SFFR) as well as plaque index (PI) and implant stability (Periotest) were analyzed clinically and radiologically. RESULTS. After 12 months of loading, an implant and prosthetic survival rate of 100% was observed. Minor prosthetic complications such as chipping of ceramic veneering occurred in both groups. No statistical significant differences were observed between both groups with only a minimum of bone loss, SFFR, and PI. CONCLUSION. All-ceramic implant prostheses including a prefabricated anatomically shaped healing abutment achieved comparable results to titanium-based restorations in the posterior region. However, observational results indicate a benefit as shaping the peri-implant soft-tissue with successive provisional devices and subsequent compression of the soft tissue can be avoided.

Bladder cancer remains the 10th most common cancer worldwide. In recent years, metformin has been found to have potential anti-bladder cancer activity while high concentration of IC₅₀ at millimolar level is needed, which could not be reached by regular oral administration route. Thus, higher efficient agent is urgently demanded for clinically treating bladder cancer. Here, by conjugating artesunate to metformin, a novel artesunate-metformin dimer triazine derivative AM2 was designed and synthesized. The inhibitory effect of AM2 on bladder cancer cell line T24 and the mechanism underlying was determined. Anti-tumor activity of AM2 was assessed by MTT, cloning formation and wound healing assays. Decreasing effect of AM2 on lipogenesis was determined by oil red O staining. The protein expressions of Clusterin, SREBP1 and FASN in T24 cells were evaluated by Western blotting. The results show that AM2 significantly inhibited cell proliferation and migration at micromolar level, much higher than parental metformin. AM2 reduced lipogenesis and down-regulated the expressions of Clusterin, SREBP1 and FASN. These results suggest that AM2 inhibits the growth of bladder cancer cells T24 by inhibiting cellular lipogenesis associated with the Clusterin/SREBP1/FASN signaling pathway.

Effects of Si and Ca additions on the mechanical properties of AM60 based Mg alloys have been investigated. Hardness of the AM60 based Mg alloys reached a maximum value after aging for approximately 33 hours but the amount of hardness increase was negligible. The poor age hardening response of the alloys was due to low Al content, which implies that Al content must be >6 wt.% to observe age hardening effect. The tensile and yield strength increased with increasing Al, Si, and Ca content but elongation decreased with increasing Al and Si content. The best mechanical properties obtained in AM 40-2.5Si-0.2Ca alloy after T4 heat treatment were as follows; tensile strength 193.4 MPa, yield strength 79.2 MPa, and elongation 11.2%. High temperature property obtained from creep test was also improved by introducing $Mg_2Si$ which has high hardness, high melting temperature and low thermal expansion coefficient.

The response of chickpea (Cicer arietinum L.) to dual inoculation with Rhizobium (R) and arbuscular mycorrhiza (AM), nitrogen (N) and phosphorus (P) was studied on spore abundance and colonization of AM, nodulation, growth, yield attributes and yield. In all the parameters of the crop the performance of Rhizobium inoculant alone was superior to control. Dual inoculation with Rhizobium and AM in presence of P performed the best in recording number of spore $100g^{-1}$ rhizosphere soil and root colonization, number and dry weight of nodule, dry weights of shoot and root, number of pod $plant^{-1}$, number of seed $pod^{-1}$, seed and stover yields of chickpea. The maximum seed yield of 3.33 g $plant^{-1}$ was obtained by inoculating chickpea plants with Rhizobium and AM in association with P. From the view point of nodulation, growth, yield attributes and yield of chickpea, dual inoculation with Rhizobium and AM along with P was considered to be the balanced combination of nutrients for achieving the highest output from cultivation of chickpea in Shallow Red Brown Terrace Soil of Bangladesh.

The energy efficiency and bandwidth efficiency are two important criterion in designing a modulation scheme Especially the constant envelope property must be considered as in the non-linear channel tht exit, for example in the nonlinear amplifiers for satellite repeater. The Q$^{2}$AM(Quadrature Quadrature Amplitude Modulation) is a new modulation scheme which combines the Q$^{2}$PSK(Quadrature Quadrature Phase Shift Keying) scheme which increases the signal space dimension and the QAM scheme which increases the bandwidth efficiency using the multi-level signal. The Q$^{2}$AM scheme has by far superior spectrum efficiency compared with the existing modulation schemes. Applying this scheme in the non-linear communication system increses the bandwidth efficiency but cannot envelop property. In this paper, a new system architecture is suggested which satisfies the large spectrum efficiency and constant envelope property by implementing the linear block coding prior to the Q$^{2}$AM modulation. the system has improved in performance by gaining the constant envelope and the additional coding gain. We able to observe the performance improvement of the suggested system(at BER=10$^{-5}$ ) of 4.4 dB for the 16-QAM and 0.7 dB for the Q$^{2}$PSK under the exact spectrum efficiency.

The purpose of this study was to report the effect of a combination of Sa-am five-element acupuncture and eight-principle pharmacopuncture (EPP) for the treatment of an essential tremor (ET). This study reviewed the medical records treated at OO Korean medical hospital for ET by using diverse types of acupuncture without herbal medicine, other types of physical therapy, and western medication related ET or Parkinson's disease and was performed after the approval of the institutional review board (IRB). The three cases that were finally selected were then extracted and reviewed. The three cases that were finally selected involved three women in their 70s to 80s. The evaluation of the progress was made by using the numeric rating scale. A combined treatment, the method of liver excess (肝乘格), from among Sa-am five-element acupuncture, and Hwangyeonhaedoktang EPP at CV23 and CV17, was applied to all cases. In all three cases, the ET was improved, and recurred ETs improved with the same treatment. The results suggest that the combined treatment of Sa-am five-element acupuncture and Hwangyeon-haedoktang EPP may be effective for treating an ET, even though this conclusion is based on only three cases.
