The purpose of this study is to identify how tales are accepted and embodied as a new work in dance as performing arts, which are getting attention for its rapid growth in the area of cultural industries. Major performances of recently created and performed ancient tales including Baridaegi, Chun-Hyang story, Yeonohrangseohnye are analyzed here. With acceptance of tales into dance, vitality of creation by the eternal word of mouth, rich information contained in each tale and the variety of interpretation showed the possibility of a new interpretation based on the existing perspectives. There are three kinds of acceptances: diversification of narrative techniques of the subject, adoption of the issue of moral values as a topic, and acceptance of tradition and national consciousness. To satisfy the fundamental concern about the universe and human, and to create both worldwide and Korean dance contents, the images of tales are being reinterpreted into a new dimension beyond the boundary of time.

This study aimed to investigate how child neglect abuse by parents, children's intimacy with teachers and peer attachment influenced boys' and girls' psycho-social maladjustment(aggression, social withdrawal and depression). The subjects were 2,264 elementary school students(boys: 1,180, girls: 1,084) in upper grades participating in the Korea Child Youth Panel Surveys. The data were analyzed with descriptive statistics, correlations and hierarchical regressions. The main results of this study were as follows. Firstly, regardless of children's sex, as child abuse levels by parents are higher, so children's aggression levels are higher. Also, children's intimacy with teachers and peer attachment moderated the effects of child neglect abuse by parents on both boys' and girls' aggression. But the patters of moderating effects were differed in children's sex. Secondly, child neglect abuse by parents didn't influence boys' and girls' social withdrawal and boys' peer attachment moderated the effects of child neglect by parents on boys' social withdrawal. Finally, child abuse by parents strongly influenced boys' depression, but child neglect by parents strongly influenced girls' depression. Also, there were no moderating effects of children's intimacy with teachers and peer attachment on the relation between child abuse neglect by parents, and boys' and girls' depression.

A semiconductor manufacturing process is the complicate and dynamic process, and consists of many sub-processes. An etching process is the most important process in the semiconductor fabrication. In this paper, the decision support system based upon data mining and knowledge discovery is an important factor to improve the productivity and yield. The proposed decision support system consists of a neural network model and an inference system based on fuzzy logic Firstly, the product results are predicted by the neural network model constructed by the product patterns that represent the quality of the etching process. And the product patters are classified by expert's knowledge. Finally, the product conditions are estimated by the fuzzy inference system using the rules extracted from the classified patterns. Prediction of product qualities can be linked to each input and process variables. We employ data mining and intelligent techniques to find the best condition of the etching process. The proposed decision support system is efficient and easy to be implemented for the process management based upon expert's knowledge.

In this study, we identified spatial and temporal patterns of reservoir trophic state within Keum-river watershed and analyzed correlations between chlorophyll-$a$ (Chl-$a$) and water quality parameters including conductivity and total phosphorus (TP). The reservoirs were separated into three trophic categories by the criteria of TP: 2 oligotrophic (9.3~9.4 ${\mu}g\;L^{-1}$), 15 mesotrophic (10.3~19.2 ${\mu}g\;L^{-1}$), and 14 eutrophic reservoirs (38.9~117.1 ${\mu}g\;L^{-1}$). Water quality parameters such as conductivity, TP, and Chl-$a$ reflected rainfall patterns, and the patters of annual mean TP were similar to the variation of annual mean Chl-$a$. Empirical models of Chl-$a$ against TP in reservoirs showed that statistical significance ($p$ <0.05) occurred in only some seasons and the trophic relations were modified by a washing-out effect or high non-algal light attenuation.

The objective of this study is to determine developmental pattern and cell allocation to the ICM and TE in haploid and diploid of embryos following parthenogenetic activation and in vitro fertilization. The incidence of development to blastocyst was lower in the combined treatments of ethanol stimulation and cytochalasin B as compared to the control. However, the combined ethanol stimulation and cytochalasin B treatment (diploid) accelerated development to the blastocyst as compared to the ethanol treatment alone (haploid). Significantly reduction in the average number of total cells and ICM was observed in the parthenotes alone as compared to fetilized embryos, but those of combined ethanol stimulation and cytochalasin B treatment embryos were significantly increased as compared to ethanol alone embryos. These results suggested that the ploidy affects preimplantation developmental patters and cell allocation to the ICM and TE in the porcine.

Nitric oxide (NO), a cellular messenger synthesized from L-arginine by NO synthase (NOS, EC.1.14.13.39), is considered to be a regulator of gastric secretion. In the present study, the role of NO in the regulation of exocrine secretion was investigated in rat gastric chief cells. Treatment of chief cells with carba-chol resulted in an increase in the arginine conversion to citrulline, the amount of $NO_{x}$, the release of pepsine-gen, and the level of cGMP Especially, carbachol-stimulated increase of arginine to citrulline transformation, the amount of $NO_{x}$, cGMP level and the release of pepsinogen were partially reduced by the natural NOS inhibitor, $N^{G}$-monomethyl-L-arginine (MMA) and $N^{G}$, $N^{G}$-dimethyl-L-arginine (DMA). Furthermore, MMA- and DMA-induced decrease of pepsinogen secretion showed dose-dependent patters. Activation of NOS is one of the early events in receptor-mediated cascade of reactions in gastric chief cells and NO, not completely, but partially mediates gastric secretion. Agonist-stimulated pepsinogen secretion in chief cells has been considered to be mediated in adenosine 3',5'-cyclic monophosphate pathway and/or guanosine 3', 5'-cyclic monophosphate (cGMP) pathway. Taken together, the above results suggest that partial decrease of exocrine secretion following treatment of NOS inhibitor may result from the inactivation of NOS and subsequent guano- late cyclase, and NO/cGMP pathway may play a pivotal role in exocrine secretion.

Low temperature co-fired ceramics on metal (LTCC-M) is efficient for embedding passive components with good tolerance in a module due to the dimensional stability in x and y directions by the constraint of metal core during the firing. In addition, the radiation noise can be reduced by metal core. In this paper, embedded passive components were introduced and a power amplifier module (PAM) fabricated by using the passive components was explained. The embedded passive components in test patters showed the tolerance of 10~20% and the good repeatability in tolerance of embedded passives was maintained in module fabrication. The shortened traces in multi chip modules (MCMs) make the signal delay time decreased and the embedded passives simplify the packaging processes owing to the less solder points, which enhance the electrical performance and increase the reliability of the modules. The LTCC-M technology is one of the promising candidates for RF application and is expected to expand its applications to power and high performance devices.

Model studies on the response of homgeneous earth embankment dams subjected to strike-slip fault movement have been penomed via centrifuge and finite element analysis. The centrifuge model tests have shown that crack development in earth embankment experiences two major patters: shear failure deep inside the embankment and tension failure near the surface. The shear rupture zone develops from the base level and propagates upward continuously in the transverse direction but allows no open leakage chnnel. The open tensile cracks develop near the surface of the embankment, but they disappear deep in the embankment. The functional relationship has been developed based on the results of the centrifuge model tests incorporating tile variables of amount of fault movement, embankment geometry, and crack propagation extent in earth des. This set of information can be used as a guide line to evaluate a "transient" safety of the duaged embankment subjected to strike-slip fault movement. The finite element analysis has supplemented the additional expluations on crack development behavior identified from the results of the centrifuge model tests. The bounding surface time-independent plasticity soil model was employed in the numerical analysis. Due to the assumption of continuum in the current version of the 3-D FEM code, the prediction of the soil structure response beyond the failure condition was not quantitatively accurate. However, the fundamental mechanism of crack development was qualitatively evaluated based on the stress analysis for the deformed soil elements of the damaged earth embankment. The tensile failure zone is identified when the minor principal stress of the deformed soil elements less than zero. The shear failure zone is identified when the stress state of the deformed soil elements is at the point where the critical state line intersects the bounding surface.g surface.

In this paper, we propose a novel fingerprint classification method to enhance the accuracy and efficiency of the fingerprint identification system, one of biometrics systems. According to the previous researches, fingerprints can be categorized into the several patterns based on their pattern of ridges and valleys. After construction of fingerprint database based on their patters, fingerprint classification approach can help to accelerate the fingerprint recognition. The reason is that classification methods reduce the size of the search space to the fingerprints of the same category before matching. First, we suggest a method to extract region of interest (ROI) which have real information about fingerprint from the image. And then we propose a feature extraction method which combines gray level co-occurrence matrix (GLCM) and wavelet features. Finally, we compare the performance of our proposed method with the existing method which use only GLCM as the feature of fingerprint by using the multi-layer perceptron and support vector machine.

This research has been conducted against Cheong-Ju undergraduate students. A total of 213 questionnaires was used for the data. The first purpose of this research is to analyze eating habits of food-related lifestyle of the students. The second purpose is to classify them into groups depending on their food-related lifestyle. The third purpose of this research is to identify eating out behavior patters among the groups classified by food-related lifestyle. Based on the information obtained from those results, this study would help restaurants have their marketing strategies. From the factor analysis, 6 factors of "popular-oriented group", "health-oriented group", "safety-oriented group", "decoration-oriented group", "tasted-oriented group" and "wellbeing-oriented group" were extracted. Additionally, "safety type group", "passive food groups" and "high-interest in foods group" were classified from the cluster analysis.
