본 논문에서는 사전 구조와 탐색알고리즘을 개선하여 형태소분석기의 분석 속도를 향상시켰다. 형태소분석기의 분석시간은 사전탐색과 제약검사의 비중이 크다. 따라서 형태소분석기의 처리속도는 사전 탐색 기법에 많은 영향을 받는다. 본 논문에서는 한국어 형태소분석기에서 사용되는 사전의 탐색속도 향상과 한 문서에 나타나는 동일한 어절에 대해서 cache를 사용하여 형태소분석기의 처리 속도를 빠르게 하였다. 또한 기존의 형태소분석기에서 속도 증가를 위해 사용하는 어절-형태소분석결과 사전을 활용하여 더 발전시켰다. 본 논문에서는 어절-형태소분석결과 사전을 사용할 때, 분석 속도향상을 위한 새로운 가속기법인 '하이브리드(HyBrid)'방법을 사용하여 어절-형태소분석결과 사전의 적중률을 높였다.

The effect of tumbling time(0, 1, and 2hr) on quality characteristics of cured-smoked pork retail cuts (Bolgi, Seolgit, Boseop, Dogani, Satae) of hind leg was investigated. Quality analyses indicated the retail cuts of pork hind leg are variable except for proximate composition. The Satae ham had the lowest (P<0.05) lightness (L) and highest redness (a). The Bolgi and Seolgit ham had higher hardness than the other hams. Tumbling time(0, 1, and 2hr) had no significant(P>0.05) effect on proximate composition, pH, color, texture properties, and sensory properties of ham. However tumbling decreased cooking loss for Satae ham tumbled for 2hr(P<0.05). Tumbling time was required for more than 2hr to improve quality and obtain maximum yield of retail cut hams. Further study is necessary to improve quality and obtain maximum yield of pork retail cuts of hind leg.

Purpose: To evaluate the rate of tumor response, local control, and treatment-related complications after hypofractionated radiotherapy for recurrent hepatocelluar carcinoma (HCC) less than 5 cm in size. Materials and Methods: Among the HCC patients who were treated by radiotherapy (RT) between 2006 and 2007 after the failure of previous treatment, a total of 12 patients were treated with hypofractionated RT. The criteria for hypofractionated RT was as follows: 1) HCC less than 5 cm, 2) HCC not adjacent to a critical organ, 3) HCC without portal vein tumor thrombosis, and 4) less than 15% of normal liver volume that irradiated 50% of the prescribed dose. Hypofractionated RT was performed with 50 Gy delivered in 10 fractions, at a rate of 5 fractions per week. The evaluation of tumor response was determined by CT scans performed at 3 months after the cessation of RT, followed by the evaluation of toxicity by Common Terminology Criteria for Adverse Events version 3.0. The median follow-up period after radiotherapy was 18 months. Results: A complete response (CR) was achieved in 5 of 12 lesions (41.7%) at CT performed at 3 months after the cessation, whereas the overall complete response was observed in 7 of 12 cases (58.3%). In-field local control rate was sustained in 83.3% of patients. All patients developed intra-hepatic metastases except for 2 patients. The overall survival rate was 90.0% at 1 year and 67.5% at 2 years, respectively. Three patients developed Grade 1 nausea during RT and 1 patient showed a progression of ascites after RT. There was no grade 3 or greater treatment-related toxicities. Conclusion: Hypofractionated RT for small-sized HCC as a salvage therapy showed a 58.3% CR rate and 83.3% of local control. Fifty Gy administered in 10 fractions of partial liver irradiation is considered as a tolerable dose that does not cause severe complications.

Hypofractionated radiotherapy prescribes high dose once. Due to this there's a bad point that patients are exposed much dose in normal organ. But recently the study making up for a limit is continuing. Cause of preference of this kind of development of therapy technic and high-energy photon beam, patients can be exposed to additional radiation. Because photoneutron is created by photonuclear reaction. So, in this study I measured photoneutron and analyzed by DVH amounts of radiation from the treatment plan that was used to acute, metastatic pelvis cancer patients who was treated by hypofractionated radiotherapy applied IMRT. As a result, incidence of photoneutron based on the hypofractionated radiotherapy was not a big difference in proportion to the dose fractionation. Protective effects of normal organ by hypofractionated radiotherapy applying IMRT is relatively high compared to 3D CRT but also photoneutron was in created. So a proper treatment plan and a best therapy should be considerated.

The objective of this study was to investigate the effects of an enriched diet supplemented with aqueous fibrolytic enzyme products (FEP) on In vitro fermentation and growth performance of Hanwoo Steers. Total mixed ration combined with fibrolytic enzyme products showed a slight increase in the pH level on In vitro fermentation. Acetate ratio in volatile fatty acids, and the concentration of total volatile fatty acids were significantly greater at 12hr and 24hr after cultivation (p<0.05). Dry matter digestibility was significantly increased in groups supplied with aqueous fibrolytic enzyme products at 24hr after cultivation (p<0.05). In a rearing trial, the average daily gain and feed efficiency improved in the treatment groups supplied with aqueous fibrolytic enzyme products. Nutrient digestibility such as DM, crude fiber, NDF, and ADF digestibility were also significantly increased with the addition of aqueous fibrolytic enzyme products (p<0.05). Therefore, the aqueous fibrolytic enzyme products supplementation on In vitro fermentation is effective in improving the condition of rumainal fermantation. Also two kinds of aqueous fibrolytic enzyme products were found to be effective in improving the average daily gain and feed efficiency in Hanwoo Steers.

Purpose: This study was performed to objectively evaluate the rate of tumor response to hypofractionated radiotherapy for advanced squamous cell carcinomas of the head and neck. Materials and Methods: Thirty-one patients with advanced squamous cell carcinoma of the head and neck, who were treated by hypofractionated radiotherapy with 3 Gy per fraction for palliative purpose between 1998 and 2008, were reviewed retrospectively. Every tumor-volume was measured and evaluated from CT (computed tomography) images obtained before and 2~3 months after radiotherapy. The radiation toxicity was assessed during and after radiotherapy. A statistical analysis was performed to investigate overall survival, progressionfree survival, and the prognostic factors for survival and response. Results: The median age of the study patients was 70 years. In addition, 85% of the patients were in stage 4 cancer and 66.7% had an ECOG performance status of 1~2. The mean tumor-volume was 128.4 cc. Radiotherapy was administered with a total dose of 24~45 Gy (median: 36 Gy) over 10~25 days. Twenty-nine patients were treated with 30 Gy or more. The observed complete response rate was 12.9% and the partial response rate was 61.3%. Median survival time was 8.9 months and the 1-year progression-free survival rate was 12.9%. The treatment response rate was confirmed as a prognostic factor in the rate of survival. The primary site, stage, tumor-volume, radiotherapy field and overall radiation-dose showed a significant relationship with survival and treatment response. No grade 4 toxicity was observed during and after radiotherapy. Conclusion: There was an objective tumor-regression in about 74% of patients treated by hypofractionated radiotherapy. Further evaluation is needed to select the appropriate fraction-size and patient who may require the additional radiotherapy.

The seismic interpretation was carried out to understand the evolution of the Sora and North Sora Sub-basins, South Sea of Korea. Both sub-basins belong to the Domi Basin, which is located in the northeastern margin of East China Sea Basin with Fukue Basin of Japan. Age assignment of each strata in this study was based on the data of boreholes and seismic interpretation in NW Japan. Four regional horizons were identified, and five geological units; Y(basement), Q(Eocene$\sim$Middle Oligocene), M(Middle Oligocene$\sim$Early Miocene), L(Early Miocene$\sim$Late Miocene) and D(Late Miocene$\sim$Present) groups in ascending order. Structural trends of the main boundary faults and the basin-fill sediment are different between the Sora and North Sora Sub-basins; i.e., trend of the main boundary-faults, dip of horizons, distribution of basin and development of growth fault. These results imply that the Sora Sub-basin would have opened earlier than the North Sora Sub-basin.
