We propose a method to improve search time and space complexity in statistical machine translation architectures, by employing linguistic bracketing information on the source language sentence. It is one of the advantages of the probabilistic formulation that competing translations may be compared and ranked by a. principled measure, but at the same time, optimizing likelihoods over the translation spa.ce dictates heavy search costs. To make statistical architectures practical, heuristics to reduce search computation must be incorporated. An experiment applying our method to a prototype Chinese-English translation system demonstrates substantial improvement.

This paper introduces the Interactive Power Electronics Seminar - iPES - a new software package for teaching of fundamentals of power electronic circuits and systems. iPES is constituted by HTML text with Java applets for interactive animation, circuit design and simulation and visualization of electromagnetic fields and thermal issues in power electronics. It does comprise an easy-to-use self-explaining graphical user interface. The software does need just a standard web-browser, i.e. no installations are required. iPES can be accessed via the World Wide Web or from a CD-ROM in a stand-alone PC by students and professionals. Due to the underlying software technology iPES is very flexible and could be used for on-line learning and could easily be integrated into an e-learning platform. The aim of this paper Is to give an introduction to the iPES-project and to show the different areas covered. The e- learning software is available at no costs at $\underline{www.ipes.ethz.ch}$ in English, German, Japanese, Korean, Chinese and Spanish. The project is still under development and the web page is updated in about 4 weeks intervals.

To enhance thermal efficiency of thermal facility through recovery of low and medium temperature waste heat, 1MW organic Rankine cycle system was designed and developed. The exhaust gases of $175^{\circ}C$ at two 100MW power plants in pohang steel works were selected as the representative of low and medium temperature waste heat in industrial process for the heat source of the organic Rankine cycle system. HCFC-123, a kind of harmless refrigerant, was chosen as the working fluid for Rankine cycle. The organic Rankine cycle system with selected exhaust gases and working fluid was designed and constructed. From the operation, it was confirmed that the organic Rankine cycle system is available for low and medium temperature waste heat recovery in industrial process. The optimum operating manuals, such as heat-up of hot water, turbine start-up, and the process of electric power generation, were derived. However, electric power generated was not 1MW as designed but only 670kW. It is due to deficiency of pump capacity for supply of HCFC-123. So it is necessary to increase the pump capacity or to decrease the pressure loss in pipe for more improved HCFC-123 supply.

This paper aims to analyze pronunciation variations of loanwords produced by Korean and improve the performance of pronunciation modeling of loanwords in Korean by using syllable-based segmentation and phonological knowledge. The loanword text corpus used for our experiment consists of 14.5k words extracted from the frequently used words in set-top box, music, and point-of-interest (POI) domains. At first, pronunciations of loanwords in Korean are obtained by manual transcriptions, which are used as target pronunciations. The target pronunciations are compared with the standard pronunciation using confusion matrices for analysis of pronunciation variation patterns of loanwords. Based on the confusion matrices, three salient pronunciation variations of loanwords are identified such as tensification of fricative [s] and derounding of rounded vowel [ɥi] and [$w{\varepsilon}$]. In addition, a syllable-based segmentation method considering phonological knowledge is proposed for loanword pronunciation modeling. Performance of the baseline and the proposed method is measured using phone error rate (PER)/word error rate (WER) and F-score at various context spans. Experimental results show that the proposed method outperforms the baseline. We also observe that performance degrades when training and test sets come from different domains, which implies that loanword pronunciations are influenced by data domains. It is noteworthy that pronunciation modeling for loanwords is enhanced by reflecting phonological knowledge. The loanword pronunciation modeling in Korean proposed in this paper can be used for automatic speech recognition of application interface such as navigation systems and set-top boxes and for computer-assisted pronunciation training for Korean learners of English.

This research aims to suggest a gamified smart learning design for Korean EFL young learners' speaking proficiency. Gamification is the use of game-thinking and game mechanics in non-game contexts to engage users in solving problems. Thus, the gamified smart learning as gamification in education is designed not only to elicit students' participation but also to enhance speaking skills. Especially, this research based on the results of a pilot study is focused on easing the burden of homework as well as engaging the speaking English game for the primary students with a relatively short attention span. The game elements utilized in this study are competition, rewards, customized characterization and so on. Kakao Talk is selected for this gamified smart learning research because of its ease of accessibility, and multiple applicable functions for language learning such as voice recording, text messaging and sharing videos or photos. Gamification in smart learning can be a means of productive approach to contemporary EFL teaching and learning.

The purpose of this study is development of 'F1 in Schools Program' for elementary school student and validation of the program. Fifteen students were originally chosen from the W elementary school in Cheongju, Chungcheogbuk-Do. The children were tested on their understanding of science and 'F1 in Schools Program'. After developing the 'F1 in Schools Program', it was used in the classroom to evaluate applicability and to examine the responses from students, parents and schools. The program consists of 60 classes and the time of each class is 40 minutes. This study was conducted for 10 days from January 22nd, 2007 to February 2nd, 2007. CAD(Computer Aided Design), CFD(Computation Fluid Dynamics), CAM(Computer Aided manufacturing) and CNC Machine were used in this study and proved to be good materials for students in that they increased the students' participation and imagination. However, the children's cognitive and creative abilities as well as manuals written in English hampered the process. Most students, parents, schools seemed to be satisfied with use of the program. However, the schools showed that there was not enough understanding of the program as a whole. The processes with which students build and inspect using the $CO_2$Model Car not only improves the processing of the model but also enhanced the students scientific understanding related to the car speed.

Purpose : The objective of this study is to serve guidelines for the investigation and management of uterine myomas with KM therapies. Methods : English-language articles from PubMed and Korean-language articles from the database of the journal of oriental gynecology were reviewed from 2000 to 2005, using the key words 'uterine myoma', 'uterine leiomyoma', 'fibroid', 'uterine artery embolization', 'endometrial ablation', 'myomectomy', and jagungguenjong(子宮筋腫)'. Results and Limits : The areas of clinical practices considered in formulating this guideline are assessment, KM therapies, medical treatments, myolysis, selective artery occlusion, endometrial ablation and surgical therapies including myomectomy and hysterectomy. Implementation of this guideline would optimize the decision-making process of women with uterine myomas and further investigation or therapy of their KM doctors. But we don't have abundant evidences of clinical trials of uterine myoma treated with KM therapy, though we treat or manage that with every-day clinical practices. Moreover cultural gaps between Korea and other western countries make many differences in the attitude to surgical therapies, especially hysterectomy. So it is very difficult to compare W therapies with other therapies. Moreover it is much difficult to estimate cost-effectiveness and benefit of those therapies in QOL. Conclusions : The majority of uterine myoma is asymptomatic and will not require any intervention or further investigation. But unmarried women who wish to marry and get pregnant want to find safe therapy for their asymptomatic uterine myomas. In that case, most of the patients prefer non-surgical therapy to surgical therapy. So KM herbal medicinal therapy is a good alternative method for those patients. For the symptomatic myomas, hysterectomy offers a definitive solution. However, it is not the best solution for women who wish to preserve their uterus. So KM therapy is a good alternative for them. But the predicted benefits of alternative therapies including KM therapy must be carefully weighed against the Possible risks of these therapies. To improve the quality of life of both women with asymptomatic and symptomatic myomas, selecting and treating patients should be done carefully. Moreover, the effect of KM therapy has to evaluated, comparing the possible situation without treatment and the benefit of constant treatment as a health-care system.

The Korean Society of Animal Science (KSAS) was officially born on October 8, 1956 under the leadership of Professor Sang W. Yun of Seoul National University, Seoul, Korea a few years after the end of the Korean War. At that time, there were 0.9 million Korean native cattle, 1.3 million pigs and 8.9 million chickens in Korea. Per capita income for Korea (US$ 66) or China (US$ 59) was about 10% of Asian's average income (US$ 513) in 1956. Korea produced less than 0.2 million M/T of formula feed and consumed 6.1 kg/person/year of animal products. One could say that Korea was an example of an under-developed country in the world. Although the first issue of the Proceedings of the KSAS was published on October 28, 1958, regular quarterly journals of the KSAS were not published until March 1, 1969. Major activities other than publishing its journal were: holding an annual meeting and/or scientific forum at national or international level. The Asian-Australasian Association of Animal Production Societies (AAAP) was founded on September 1, 1980 at Kuala Lumpur, Malaysia with founding members from Australia, Indonesia, Japan, Korea, Malaysia, NZ, Philippines and Thailand. Thirteen AAAP Animal Science Congresses have been held in its 28 year history. Hosting countries were Malaysia (1980), Philippines (1982), Korea (1985), NZ (1987), Taiwan (1990), Thailand (1992), Indonesia (1994), Japan (1996), Australia (2000), India (2002), Malaysia (2004), Korea (2006) and Vietnam(2008). In 1988, significant progress of the AAAP was made by creating an official English journal of the AAAP entitled "Asian-Australasian Journal of Animal Sciences (AJAS)" under the initiative of the KSAS. This journal is now published monthly and distributed to more than 50 countries in the AAAP region and the world. It should be mentioned that the KSAS was able to successfully host the $3^{rd}$ AAAP Animal Science Congress in 1985 and the 12th in 2006, as well as the $8^{th}$ WCAP in 1998. During the last 50 years of KSAS history, per capita income of Korea increased to US$ 17,690 (268 fold), formula feed production increased to 15 million M/T (97 fold) and consumption of animal products increased to 105 kg/person/year (17 fold). Cattle, pig and chicken numbers also increased to 2.5 million (2.8 fold), 9 million (7.4 fold) and 119 million (13 fold). This trend was also found for China and Asia, even if the rate of growth was slightly lower than that of Korea. It is expected that a similar rate of growth in economics, animal numbers, formula feed production and animal protein intake will likely be achieved by other Asian countries in the $21^{st}$ century with somewhat lower rate of development than that of Korea.

The purpose of this study is to investigate the effects of the low power Helium Neon-Infra Red(HeNe-IR) laser and the special electromagnetic therapeutic apparatus stimulation, which is usually designated as TDP by using the initial of Tending Diancibo Pu which is the Chinese inscribed with English, on wound healing in rat. The seventy-five Sprague-Dawley adult female and male rats were assigned to the experimental and control groups. Each rat was anesthetized with pentobarbital sodium, and three full-thickness incisions with 12mm length wert made on the back of the half cf the rats and three deep second degree burns were made on the back of the remainder of the rats. From 34 hours after being injured, the rats of the experimental laser group were irradiated with the 157mW electric power HeNe-IR laser for 2 minutes every day and the rats of the experimental TDP group were stimulated with TDP irradiation with the 4km spot distance for 20 minutes every day during the 17 days. The rats were sacrificed and the wound parts of its were incised on the first day, 4th day, 7th day, 10th day and 17th day respectively after the beginning of wound treatment with laser and TDP irradiation. The incised wound parts were processed appropriately for the light microscopic and electron microscopic examination. The length of incised wound was measured with microcaliper before the wound part was incised. There was a significant decrease in the length of the incised wound of the experimental laser and TDP group, compared with that of control group at 4th day, 7th day and 10th day(p<0.01) after surgery. Through the histological examination of the wound site, the more rapid epithelialization and collagen formation in experimental groups were showed, compared with control group. The histological results were analyzed and summarized as the follows; The epidermis begins to be regenerated and the granulation tissue begins to be changed to the mature pattern in the H-E stained incised skin of the laser and TDP treatment group on the 4th day. The epidermis shows the complete regeneration and the granulation tissue in the dermis in mostly to be matured in the laser and TDP treatment group on the 7th day, compared with control group. The chronic inflammatory cells are oberved and the necrosis of the collagen fibers are partially observed in control group on the 10th day. The dermis of the laser and TOP treatment group reveals relatively compactly arranged collgen bundles with the mature collagen fibers on the 10th day. The epidermis and dennis of the laser and TDP group are repaired normally and the hair follicles are well regenerated on the 17th day. The mild edema and the granulation tissue is observed in the dermis of the control groups and the delayed treatment process is observed on the 17th day. The Most of proliferated collagen fibrils are found to be compact and regular in electron micrograph of burn skin of the laser treatment group on the 10th day hut the interstitial eadema and some inflammatory cells are found in the control group. The above results suggest that through the visual and histological examination the epithelized epithelium and the proliferation of the collagen liters in the dermis occur very effectively with the low power laser treatment and the TDP treatment in the incised wound healing and the burn wound healing.
