        Mapping Algorithm of Semantic Interpretation in Korean Multiple Nominative Constructions

        Yoon-Ho Jeon 한국언어연구학회 2019 언어학연구 Vol.24 No.3

        This paper investigates the relation between Korean nominal markers (case, topic, focus stress, etc.) and the semantic interpretations each of them induces in multiple nominative constructions (MNC). Adopting Jeon’s (2019b) proposal, which is the revised version of Diesing’s (1992) mapping hypothesis, and Ha’s (2014) applicative approach, I show that in MNCs a generic reading is licensed in the restrictive clause (TopP/FocP) by binding by the null generic operator GEN and an existential/episodic reading can be derived by existential closure in ApplP, which is the nuclear scope. It will be shown that nominative-marked NPs in MNCs are all licensed by an applicative head and are represented in the vP-type projection, ApplP. This mapping structure is supported by the analysis in Jeon (2019b), which presents the evidence against the lexical division of stage- and individual- level predicates, arguing for a distinction dependent on syntactic contexts.

This study was accomplished to analysis and survey on the experimental and practical science education of high school in korea for the consecutive study of the an analysis and survey on the experimental and practical science education of middle school in korea(Lee, Yoon-Jong et al., 1997). The status of facilities, management for the experiment, practices, teaching methods in high schools have been investigated. The present status and reasonable management of the high school science education have been grasped from the questionaires. To do this 165 high school science teachers, 1977 students and 80 principals of high schools in Korea are administered questionaires of Science Education Research Institute of Kyungpook National University(1997). The results of this study are as follows : The reasonable management for experiments and practices of science education were scanty in the high school around the urban and rural school owing to the shortage of facilities and equipments, crowded class, excessive class works for teacher, excessive contents of present textbooks and insufficiency of the administrative supports etc. The current teaching method of high school science has emphasized knowledge. This fact does not satisfy the objective of learning due to lack of the teaching method. Desirable directions for the improvement of present status of high school science education were proposed in this paper.

        Ethanol Extract of Ganoderma lucidum Augments Cellular Anti-oxidant Defense through Activation of Nrf2/HO-1

        Lee, Yoo-hwan,Kim, Jung-hee,Song, Choon-ho,Jang, Kyung-jeon,kim, Cheol-hong,Kang, Ji-Sook,Choi, Yung-hyun,Yoon, Hyun-Min KOREAN PHARMACOPUNCTURE INSTITUTE 2016 Journal of pharmacopuncture Vol.19 No.1

        Objectives: The mushroom Ganoderma lucidum has been widely used as a traditional herbal medicine for many years. Although several studies have focused on the anti-oxidative activity of this mushroom, the molecular mechanisms underlying its activity have not yet been clearly established. The present study investigated the cytoprotective effect of ethanol extract of Ganoderma lucidum (EGL) against oxidative stress (hydrogen peroxide, $H_2O_2$) and elucidated the underlying mechanisms in a C2C12 myoblast cell line. Methods: Oxidative stress markers were determined by using the comet assay to measure reactive oxygen species (ROS) generation and deoxyribonucleic acid (DNA) damage. Cell viability and Western blotting analyses were employed to evaluate the cellular response to EGL and $H_2O_2$ in C2C12 cells. Transfection with nuclear factor erythroid 2-related factor 2 (Nrf2)-specific small interfering ribonucleic acid (siRNA) was conducted to understand the relationship between Nrf2 expression and $H_2O_2$-induced growth inhibition. Results: The results showed that EGL effectively inhibited $H_2O_2$-induced growth and the generation of ROS. EGL markedly suppressed $H_2O_2$-induced comet-like DNA formation and phosphorylation of histone H2AX at serine 139 ($p-{\gamma}H2AX$), a widely used marker of DNA damage, suggesting that EGL prevented $H_2O_2$-induced DNA damage. Furthermore, the EGL treatment effectively induced the expression of Nrf2, as well as heme oxygenase-1 (HO-1), with parallel phosphorylation and nuclear translocation of Nrf2 in the C2C12 myoblasts. However, zinc protoporphyrin IX, a HO-1 inhibitor, significantly abolished the protective effects of EGL against $H_2O_2$-induced accumulation of ROS and reduced cell growth. Notably, transient transfection with Nrf2-specific siRNA attenuated the cytoprotective effects and HO-1 induction by EGL, indicating that EGL induced the expression of HO-1 in an Nrf2-dependent manner. Conclusion: Collectively, these results demonstrate that EGL augments the cellular anti-oxidant defense capacity through activation of Nrf2/HO-1, thereby protecting C2C12 myoblasts from $H_2O_2$-induced oxidative cytotoxicity.

        This paper presents an integrated machining error compensation without measuring cutting force in micro end-mill. To compensate machining error, we consider new tool path. In order to determine the compensated tool path, two machining error parameters are defined and modeled using the SEM images. Experiments are carried out to validate the approaches proposed in this paper. In result, we identify the proposed methods are effective to compensate for machining errors.

      • Southern Blot Hybridization법을 이용한 악성 림프종의 면역유전형에 관한 연구

        전호종,기근홍,김윤신,이미숙,이미자,장원재,장숙진,박영진,정춘해,정종훈,양성훈,이광민 조선대학교 1994 The Medical Journal of Chosun University Vol.19 No.2

        Immunogenotyping using gene rearrangement analysis has emerged as a precise laboratory aid in the diagnosis and classification of malignant Iymphoid neoplasms. The lineage and clonality of the malignant Iymphoid neoplasms can be identified by the demonstration of rearrangements of antigen receptor genes of the immunoglobulin and T-cell receptor genes. The analysis of the gene rearrangements on the malignant Iymphoid neoplasms are also useful as a sensitive unique clonal markers to detect early recurrence in patients with malignant Iymphoid neoplasms after treatment. To analyze the sensitivity and specificity of gene rearrangements in the diagnosis of malignant Iymphoid neoplasms. 24 cases of malignat Iymphoma were examined by Southern blot hybridization using CTβ-T cell receptor β chain gene-DNA probe and JH-immunoglobulin heavy chain gene-DNA probe. The results of the immunogenotypings using Southern blot hybridization disclosed high correlation between the immunophenotyping using immunohistochemical stain with monoclonal antibodies (B-cell Iymphoma 84.2%. T-cell Iymphoma 75% ). The analysis of the gene rearrangement of the angioimmunoblastic lymphadenopathy(AILD) and unclassifiable Iymphoma using immunohistochemical stain could resolve the monoclonality and lineage . Rearranged bands to the CTβDNA probe were observed in one case out of 2 cases of AILD. One case of unclassifiable Iymphoma showed rearranged bands to the CTβ DNA probe. There were no rearrangements in reactive follicular Iymphoid hyperplasia and paracortical Iymphoid hyperplasia. In conclusion, DNA gene rearrangement study should be applied to differentiate the clonality and cell lineage in the malignant Iymphoma with indistinctive immunophenotype.

        In English, a focused word with new information receives a pitch accent. This paper examines how English native speakers and Korean speakers produce and perceive focus in English yes-no questions. The production experiments show that native speakers realize an appropriate intonation of yes-no questions, in which a focused word has a low pitch accent followed by a high phrasal accent and a high boundary tone. However, Korean speakers usually give a high tone to a focused word. In a like manner, the perception experiments show that English native speakers judge a word with a low tone to be focused, while Korean speakers have difficulty in comprehending a focused word realized as a low tone. And it is found that Korean speakers tend to perceive low tones on sentence initial and final focused words better than those on sentence medial focused words, and they often perceive a word with a relatively high fundamental frequency or a sharp rise of fundamental frequency as a focused word. This paper shows that Korean speakers have trouble to produce and perceive an appropriate tonal pattern of a focused yes-no question, and that can cause confusion in a conversation with native speakers.

        농업용 저수지의 물리적 인자가 수질에 미치는 영향

        전지홍,윤춘경,함종화,김호일,황순진 한국육수학회 2002 생태와 환경 Vol.35 No.1

        The effect of physical parameters on water quality was analyzed using monitoring data of 193 agricultural reservoirs. The retention time of reservoirs(t_d) ranged between 10 and 140 days, and the ratio of drainage area(DA) to reservoir surface area(SA) was between 10 and 120. Both ratios of DA/SA and total area(TA)/ reservoir storage(ST) in Korean agricultural reservoirs were relatively greater than those in natural lakes in other countries. As retention time was plotted against DA/SA ratio, it was shorter in Korean reservoirs than natural lakes. The semi-logarithmic relationship between TA/SA and t_d was t_d = 42.21(TA/ST)^-1 (n = 50, R^2 = 0.89). While areal loading of total phosphorus(TP) was below 4 gTP·m^-2·yr^-2 in general, it exceeded 10 gTP·m^-2·yr^-1 in reservoirs where DA/SA ratio was greater than 100, which implies that areal loading of TP increases as DA/SA ratio increases. Chl-a concentration was positively related with the mean depth of reservoir, implying the higher Chl-a concentration with deeper the mean depth. Therefore, the deeper reservoir might be advantageous in water quality management perspective if other morphological conditions are similar. The empirical regression equation using physical parameters was also suggested in the estimation of TP concentration in the reservoirs. Combined information presented in this paper might be applicable to the water quality management in agricultural reservoirs.
