The purpose of this study is to review and criticize the articles that analyzed Frozen by using the semiotic method of Greimas. The study also aims to apply the semiotic method of Greimas correctly to find the deep structure of the narrative of Frozen. The results of the narrative analysis based on the actantial model and the semiotic square show that Frozen is not Elsa's heroic narrative but Anna's one. Because Elsa and Anna are the opposing elements in this narrative, the success of Anna is the failure of Elsa. Frozen does not convey the subversive message about the gender roles by representing an independent and active woman who resists the patriarchal discourse. Instead, Frozen reproduces the conformist ideology by saying that love is the most valuable thing and that everyone should accept the role given to him/her by the community.

A new control method for precision robust speed control of a PMSM(Permanent Magnet Synchronous Motor) using load torque observer is presented. Using this system, we can more precisely evacuate of vestibular function. Until now a rotating chair system, so called 2D-stimulator, which has vertical rotate axis is used to make dizziness. However, an inclined rotating chair system witch is called 3D-stimulator is needed to obtain the precise dizziness data. This 3D-stimulator include unbalanced load caused by unbalanced center of mass. In this case, new compensation method is considered to obtain robust speed control using load torque observer. To reduce the effect of this disturbance, we can use dead-beat observer that has high gain. The application of the load to torque observer is published in for position control. However, there is a problem of using speed information such as amplifying effect of noise. Therefore, we can reduce a noise effect by moving average process. The experimental results are depicted in this paper to show the effect of this proposed algorithm.

Date of Bureau of Statistics, including those of Bank of Korea and KDI, in 1995 indicates a market scale of approximately ￦2,800,000,000 in jewelry and personal ornaments, witch points out an average growth rate of 15.3% a year for ten years from 1986 up to 1995, representing a occupancy ratio of 0.78% per G.N.P. Despite the fact that the jewelry and personal ornaments industry has the possibility of high growth it raises problems such as illegal transactions, distortion of quality grades of jewelry (price deference by appraising agencies in Diamond, fabrications of quality in Gold). Furthermore, the personal ornaments market may be said to be still at an early state, as compared with that of advanced countries, including the USA and Japan, due to the small scale of the industry's distribution firms. Accordingly, in order for us to develop the jewelry and personal ornaments industry, one of the value added projects, an improvement in the distribution system of the jewelry and personal ornaments industry. Development of techniques of production and new design, ect, are required. Futhermore, the industry is expected to develop when its importance and contribution to the national economy, a correct understanding of the long-term vision of the industry are expended to all the industries.

The coat protein (CP) gene was cloned from RNA genome of the Cucumber Mosaic Virus strain ABI (CMV-ABI) isolated in Korea. The comparisons of the nucleotide sequence of the cloned CP gene and its deduced amino acid sequences with other CP genes revealed that the CMV-ABI belongs to subgroup I (type I), CMV-ABI developed the typical mosaic symptom in infected plants. Tobacco plants (Samsun and NC82) were transformed by leaf-disc transformation via Agrobacterium, temefaciens LB4404 harboring pVCP, witch CMV-ABI CP gene was inserted into the pBI121, and a number of mature transgenic tobacco plants were developed. Southern and PCR analysis of genomic DNA from the transgenic plants showed that the CP gene was integrated into the genomes of the most of the transgenic plant. Result of the segregation patterns of resistance in T1 seedlings of the plants to kanamycin showed that the transgenic plants containing l,2 and 3 copies of CP gene were50%, 39% and 11% of the total transgenic plants, respectively.

Z. Cao had proposed NFRM(new fuzzy reasoning method) which infers in detail using relation matrix. In spite of the small inference rules, it shows good performance than mamdani's fuzzy inference method. But the most of fuzzy systems are difficult to make fuzzy inference rules in the case of MIMO system. The past days, We had proposed the MIMO fuzzy inference which had extended a Z. Cao's fuzzy inference to handle MIMO system. But many times and effort needed to determine the relation matrix elements of MIMO fuzzy inference by heuristic and trial and error method in order to improve inference performances. In this paper, we propose a MIMO fuzzy inference method with the learning ability witch is used a gradient descent method in order to improve the performances. Through the computer simulation studies for the inverse kinematics problem of 2-axis robot, we show that proposed inference method using a gradient descent method has good performances.

The Cancer Patients are rapidly growing and it became one of the main cause of death. Lately with the effect of Chemotherapy, drastically improved patients quality of life and also Prolonged Life of Cancer Patients. But the Chemotherapy not only Kill the Cancer cells but also harm to normal cells witch Cancer lots of side effect. This study was designed to identify the effectiveness of patient education to reduce side effect and help promote self care. The date was collected from October, 2001 to February, 2002 by questionary Survey Method. The subjects were 24 patients Who were and Anti Chemotherapy C University Hospital. Educated booklet contained what is Chemotherapy, what are the side effects, and to promote Self care, Pre test was given after 3-4 weeks re admission period. Analysis data was done by SPSS Program Paired t-test was used to differentiate Knowledge and difference of performing self care. Relationship in between Knowledge and promoting Self care was used Pearson Correlation. As the result of education, knowledge of self care and performance was drastically increased but the relationship in between knowledge of self care performed was not significant. Therefore it is proposed as follows: 1) Further research with experienced subjects to differentiate experience group and control group. 2) Education program need to be develop and standardize for anti cancer Chemotherapy patient. 3) During 6 cycle of Chemotherapy what is ideal number of in order to get the best result.

Objective : To observe the effectiveness of Jayeumganghwa-tang on hot flush of a breast cancer patient who takes tamoxifen. Methods : For six weeks a dosage witch contained 13.92g of Jayeumganghwa-tang was administered 3 times (30 mins after meal) per day, for improvement of hot flush. No other therapies like hormone therapy or substituted therapy were done. Results : As a result of 6 weeks of Jayeumganghwa-tang therapy, the patient who suffered hot flush on taking tamoxifen showed improvement on several indices, including frequency, intensity and point of hot flush, Beck Depression Inventory-K (BDI-K) which shows uneasiness and sadness, and also Functional Assessment Cancer Therapy - Breast (FACT-B) which is an index of life quality of breast cancer patients. But no changes on female hormones like follicle-stimulating hormone (FSH) or luteinizing hormone (LH) were observed. Conclusion : This case demonstrates 6 weeks of Jayeumganghwa-tang taking had no effect on female hormones but can reduce the hot flush by tamoxifen. This shows minimum evidence of safety and efficacy of Jayeumganghwa-tang on hot flush of breast cancer patient. However this is a single case study so further case-series research should be compiled.

Hamamelis japonica (Hamamelidaceae), widely known as Japanese witch hazel, is a deciduous flowering shrub that produces compact clumps of yellow or orange-red flowers with long and thin petals. As a part of our ongoing search for phenolic constituents from this plant, eleven phenolic constituents including six flavonol glycosides, a chalcone glycoside, two coumaroyl flavonol glycosides and two galloylated compounds were isolated from the flowers. Their structures were elucidated as methyl gallate (1), myricitrin (2), hyperoside (3), isoquercitrin (4), quercitrin (5), spiraeoside (6), kaempferol 4'-O-β-glucopyranoside (7), chalcononaringenin 2'-O-β-glucopyranoside (8), trans-tiliroside (9), cis-tiliroside (10), and pentagalloyl-O-β-D-glucose (11), respectively. These structures of the compounds were identified on the basis of spectroscopic studies including the on-line LCNMR-MS and conventional NMR techniques. Particularly, directly coupled LC-NMR-MS afforded sufficient structural information rapidly to identify three flavonol glycosides (2 - 4) with the same molecular weight in an extract of Hamamelis japonica flowers without laborious fractionation and purification step. Cytotoxic effects of all the isolated phenolic compounds were evaluated on HCT116 human colon cancer cells, and pentagalloyl-O-β-D-glucose (11) was found to be significantly potent in inhibiting cancer cell growth.
