Some planorbid snails such as Hippeutis cantori and Segmentina hemisphaerula have reported as the molluscan intermediate hosts of Neodiplostomum seoulense, one of important snail-borne human intestinal trematodes in Korea. However, one of the Korean lymnaeid snail species, Austropeplea ollular was also found to be the first intermediate ho of N. seoulense. In field-collected Austropeplea snails from Sorae and Kimpo out of se collected localities, the bifurcated cercariae of N. seoulense were shed (infection rat 0.3%), whereas no Radix auricularia and Fossaria truncatula were found shedding cercariae. Each of 12 tadpoles of Rana nigromaculata, known as the second intermedia host of N. seoulense, were exposed to 200 cercariae shed from field-collected A ollula. F tadpoles of R. nigromaculata were found to be massively infected with metacercariae o N. seoulense (recovery rate: 62.1%). Each of five rats (Sprague-Dowley strain) was or fed with 200 metacercariae, and eggs of N. seoulense were detected in the rat feces on week later. These rats were killed 4 weeks after postinfection and adult worms of N seoulense were recovered from the small intestines (recovery rate: 9%). This is the f report of A. ollula as the first molluscan intermediate host for N. seoulense in Korea.

This study was systematic review to confirm the effects of the yoga on dysmenorrhea. Seven articles were extracted from the CINAHL, the Cochrane library, Embase, PsycINFO, PubMed, and Koreamed electronic databases. Menstrual pain intensity and duration, menstrual distress, QOL, anxiety, anger, and depression levels, homocysteine, TSH, FSH, LH, and prolactin levels were decreased significantly in the yoga group, compared with control group. These findings imply that yoga are a favorable intervention for dysmenorrhea.

Objectives : The purpose of this study was to determine whether NMED-01 or NMED-02 improves laboratory test results in participants with liver function disorder. Methods : This is a randomized, placebo-controlled trial in which participants, treating physicians and data management staff were blinded to treatment group. The study was conducted at Semyung university oriental medicine hospital in Jecheon where participants with high level of serum ${\gamma}$-GTP (60-350 U/L) were enrolled. The intervention consisted of three times daily ingestion of either two capsules of placebo, NMED-01 (NeuMed. co. ltd., Seoul), or NMED-02 (NeuMed. co. ltd., Seoul) for twelve weeks. To evaluate the efficacy and safety of NMED-01 and NMED-02, we primarily evaluated the degree of decrement of serum ${\gamma}$-GPT level among three groups. Secondarily the decrement of serum ALT, AST, and triglyceride level in each group were also evaluated. Adverse effects were monitored during the twelve weeks treatment. Results : The change of ${\gamma}$-GTP level of NMED-01 group was lower than that of placebo group at the end of 12-week administration ($28.1{\pm}38.7U/L$ vs. $9.3{\pm}27.0U/L$, p=0.046). Other variables including AST, ALT, and triglyceride level were not significantly reduced. The decrement of ${\gamma}$-GPT, AST, ALT, and triglyceride level of NMED-02 group was not significant. There were no significant adverse effects or toxicities during treatment period. Conclusions : Participants receiving NMED-01 had improvement in laboratory test results. Despite a modest sample size, our results suggest that NMED-01 are safe and may be potentially effective in improving liver function. However, NMED-02 have lack of a detectable effect in this study.

This paper presents an orientation-based adaptive prediction method for effective lossless image compression. For a robust prediction, the proposed method estimates the directional information and the property near the current pixel in a support region-based fashion, not a pixel-based one which is sensitive to a small variation. We improve the prediction performance effectively by selection of the prediction pixel adaptively according to the similarity between support regions of the current pixel and the neighboring pixels. Comprehensive experiments demonstrate that the proposed scheme achieves excellent prediction performance measured in entropy of the prediction error compared to a number of conventional prediction methods such as MED, GAP, and EDP. Moreover the complexity of the proposed algorithm measured by average execution time is low compared to MED which is the simplest prediction method.

Purpose: This is a descriptive study to investigate the relevance between biological nursing science subjects (structure and function of the human body (SFHB), mechanism and effects of drugs (MED), clinical microbiology) and examination workbook items for Registered Nurse Licensure Examination (RNLE) in Republic of Korea (ROK) and the United States of America (USA). Methods: RNLE 8 workbooks which were published by the Korean Nurses Association were utilized for analysis of Korean RNLE. Saunders comprehensive review for the $NCLEX-RN^{(R)}$ examination was used for analysis of US RNLE. The relevance between items in the standard syllabuses of biological nursing science subjects (SFHB, MED, clinical microbiology) and the RNLE items of these workbooks in ROK and the USA was analyzed. Results: The relevance rates of ROK and the USA were 3.6% vs 0.4% in SFHB, 8.9% vs 23.0% in MED, and 4.5% vs 5.8% in clinical microbiology. Conclusion: In SFHB, the relevance of the RNLE in ROK was higher than that of the USA. However in MED the relevance of the RNLE in USA was higher than that of the ROK. Since medications are one of major tasks of nurses, it is necessary to increase the number of related items in the RNLE in ROK.

In this paper, a system model for transmission of 3-dimensional (3-D) signals is presented and its performance is analyzed. Unlike 2-D signals, no quadrature form expression for the 3-D signals is available. Exploiting a set of orthogonal basis functions, the 3-D signals are transmitted. As a result of computer simulation using very higher-level signal constellations, the 3-D transmission system has significantly improved error performance as compared with the 2-D system. It is considered that the principal reason for such performance improvement is much increased minimum Euclidean distance (MED) of the 3-D lattice constellations compared with the corresponding 2-D ones. When the MEDs of 2-D and 3-D lattice constellation are compared to confirm the analysis, the MED of 3-D 1024-ary constellation is around 2.6 times larger than that of the quadrature amplitude modulation (QAM). Expanding the constellation size to 4096, the MED of 3-D lattice constellation is increased by 3.2 times of the QAM.
