A user often searches a data by inputting a variant such as the abbreviation or substring of a word, or a misspelled word. The simple approach to the searching for variants is to build a variants dictionary. However, it entails enormous cost and time and can not handle variants by misspelling. Approximate searching, searching by approximate string matching, is a good approach to the searching. A problem in the approach is that it cannot handle variants by abbreviations. This paper propose a method for searching various variants including abbreviations and misspelled words, by using the trie indexing. First, this paper shows a variant matching method with the calculation of path weighted-metric. In addition, it provides variant searching algorithm to reduce the search time.

Two endemic foci of heterophyid infections were discovered in coastal villages of Puan-gun. Chollabuk-do, and Sachon-gun. Kyongsangnam-do, Korea. Fecal examina- tions were performed on 153 inhabitants of Puan-gun and 138 of Sachon-gun, using cellophane thick smear and formalin-ether sedimentation technique. The helminth egg and/or protozoan cyst positive rate was 21.5% (33/153) in Puan-gun and 39.1% (54/138) in Sachon-gun. In Puan-fun, the egg Positive rate of heterophyids was the highest, 17.6%, and that of other parasites was 0.7-2.6% by parasite species. In Sachon-gun, that of heterophyids wa's 18.8%, followed by Clonorchis sinensis (12.3%). and other parasites (0.7-5.OBEI . Twenth-two (Puan-gun) and six (Sachon-gun) heterophyid egg Positive cases were treated loth praziquantel, and adult flukes were collected from their diarrheic stools. A total of 3,284 adult flukes of Heterophyes nocens was collected from all of the 22 patients treated in Puan-gun (3-778 individually) , and other trematodes were also collected from 2- 15 patients; Ftgidiopsis sumac, Stellcntchcsmus JcEcctus, Metogoninus Wokogaupci, M. miyntci, Stictodora Juscnta, Heterophwopsis continua, Acnnthopcrwphium kurognmo, and GWmnophaELoines seoi. In Sachon-gun, M. yokognwci (3,007 specimens), H. nocens (120), aud S. falcatus (46) were collected from 5 of 6 treated patients, and H. continuo and 5. tan each from one patient. The present study revealed that heterophyid flukes, especially If. nocens and M. Wokofowai, are prevalent in the southern and western coastal areas of Korea where fresh and/or brackish water fishes are popularly eaten raw.

An information retrieval system, using exact match, needs preprocessing or query expansion to generate transliteration variants in order to search foreign word transliteration variants in the documents. This paper proposes an effective method to generate other transliteration variants from a given transliteration. Because simple rewriting of confused characters produces too many false variants, the proposed method controls the generation priority by learning confusion patterns from real uses and calculating their probability. Especially, the left and right context of a pattern is considered, and local rewriting probability and global rewriting probability are calculated to produce more probable variants in earlier stage. The experimental result showed that the method was very effective by showing more than 80% recall with top 20 generations for a transliteration variants set collected from KT SET 2.0.

People use various information for searching POI in the navigation system such as name, category, address, phone number. Most of users use name and category to search their POT. They don't know exact name in POI DB provided by Maker. They use abbreviated or generalized name as key word for searching POI. Because of these reasons, the hit ratio has been very low. In this paper, We suggest a extra DB_construction system for raising the hit ratio. It generates allomorphes DB link to the POI name in original DB. We classified the POI names in original DB into seven types of allomorph by analyzing the gathered patterns from the POI DB which has over 650,000 entries. For auto_generating the allomorphes, we made 577 rules based on the classified types. And we generated the allomorphes manually for the entries which are difficult to make the rule and has low frequency The generated allomorphes account for 35.8% of all original DB. The hit ratio is 89% under suggested system.

GFRP rebar with ribs resemble those of deformed steel rebar was developed in 2005. It was reported that ribs of the GFRP rebar were sheared off due to the lower shear strength of polymer. In this study, the basic development length of the GFRP rebar was investigated through pull-out tests, models specified in ACI440.1R-03 and -06, and empirical model derived by Cosenza et al. (2002). As a results of pull-out tests, the critical embeddment length, which is defined as the length when failure mode is changed from pull-out to bar fracture, was 20 times of bar diameter for GFRP rebar and was 15 times for steel rebar. It is believed that the basic development of the GFRP rebar is 21 times of bar diameter, which is determined from the application of average bond strength into the model equation specified in ACI440.1R-03. Compared to the model equation in ACI440.1R-06, that in ACI440.1R-03 is recommendable for design purpose. The Cosenza et al.'s model underestimates the basic development length of the GFRP rebar.

The third human case of natural infection by Heterophvopsis continuo in Korea was found in Chinju, Kyongsangnam-do. The case was a 53-year-old mn. He used to eat raw brackish and fresh water fish. After praziquantel treatment and purgation, H. continua were collected from the diarrheal stool together with Metononimw vokognwai, Heterophves nocens and Echinostona hokense. His clinical complaints were indigestion, epigastric discomport, poor appetite and fatigue. The complaints were considered rather due to heavy M. Wokoscwci infection.

Purpose: Gastric epithelial dysplasia (GED) was defined as "unequivocally neoplastic epithelium that may be associated with or give rise to invasive adenocarcinoma" and GED also represents a direct precursor of intestinal type adenocarcinoma of the stomach. The recommended treatment guidelines for GED in the medical literature are endoscopic mucosal resection (EMR) or surgery for high grade dysplasia (HGD) and annual endoscopic surveillance with biopsy for low grade dysplasia (LGD) The aim of this study was to determine the treatment plan for GED that is diagnosed by endoscopic biopsy. Materials and Methods: We enrolled 148 patients who were treated by endoscopic mucosal resection (EMR) or endoscopiccsubmucosal dissection (ESD) for GED: there were 63 patients with HGD and 85 patients with LGD and all of them were diagnosed by endoscopic biopsy from January 2006 to December 2008. The results of the final histopathologic reports after EMR or ESD were compared with the results of the endoscopic biopsies. Results: The final histopathologic results of the 148 patients with GED showed 49 (33.1%) patients with adenocarcinoma, 40 (27.0%) patients with HGD and 59 (39.9%) patients with LGD. Among the 63 patients with HGD, 34 (54.0%) patients had adenocarcinoma, 20 (31.7%) patients had HGD and 9 (14.3%) patients had LGD. For the 85 patients with LGD, 15 (17.6%) patients had adenocarcinoma, 20 (23.5%) patients had HGD and 50 (58.8%) patients had LGD Conclusion: Complete resection, including EMR or ESD, is needed for patients with GED diagnosed by endoscopic biopsy and they have HGD. For patients with LGD, EMR or ESD may be needed in addition to endoscopic surveillance with biopsy for making the correct diagnosis and proper treatment because of the possibility of adenocarcinoma.

Myelodysplastic syndrome (MDS) is a typical myeloid malignancy characterized by cell dysplasia in bone marrow. Currently, there is no therapeutic treatment for MDS. The only available therapies either relieve symptoms or prevent the development of acute myeloid leukemia (AML). This study aimed to report the effects of traditional Korean medicine (TKM) on MDS by presenting two case reports. The patient in Case 1 was diagnosed with primary MDS and regularly received acupuncture treatments and herbal medicine. In Case 2, a patient with ovarian cancer was diagnosed with secondary MDS, which resulted from an adverse reaction to chemotherapy. This patient took herbal medicine for four years and was hospitalized three times. In order to have their condition evaluated, both patients underwent regular blood tests. The patient in Case 1, who showed blood transfusion dependency, received only two blood transfusions after TKM treatment, and the person’s health condition was stable as of January 2016 without any signs of AML development. The patient in Case 2 also has stable health condition. TKM treatment effectively treated their MDS symptoms and improved their general health conditions without any adverse effects. It also prevented the rapid development of AML and maximized the effects of conservative therapy.

A small coastal village of Muan-gun, Chollanam-do, was surveyed for intesti- nal fluke infections, especially heterophyids such as Heterophwes nocens and Ftsiniopsis summc by fecal examination on 108 inhabitants. The egg Positive rate of heterophyids was very high. 75.0%, and that of other parasites was comparatively low.0.9-3.7% by parasite species . After treatment of 20 patients showing high E. P. G. with praziquantel and purging with Mgs04, total 3,864 specimens of H. nocens were collected from the diarrheic stools of all the patients treated (3-1,338 individuallyl and total 703 p. summc were harvested from 18 patients (1-170 individually), together loth several other species of flukes. Other flukes included Stictodora jlscotn (164 specimens from 4 patients), Heterophwopsis continuo (2 from 2 patients), and Gwmnophalloides seoi (4 from 3 patients). From this study, the sutra- veyed coastal area of Muan-gun, Chollanam-do was proven to be a new endemic focus of H. nocens and p. summa. The occurrence of a few infected cases surf:mists that this area should also be a low-grade endemic area of S. Juscctc, H. continuo, and G. seoi.
