Purpose: In this study we investigated improvement degree of reading ability of the student who was in a condition of dyslexia symptoms by wearing $ChromaGen^{TM}$ lenses. Methods: After wearing the $ChromaGen^{TM}$ lens for 3 months, the dyslexia symptoms corrective lens, 52 students who had suspected symptom of dyslexia were asked questions, and we measured the improvement degree of reading ability of the student. Results: The $ChromaGen^{TM}$ wearer read 110.26${\pm}$22.07 words in 1 minute, and naked yeses or glass wearing students read 106.42${\pm}$22.70 words. Reading ability of the student having suspected symptom of dyslexia were measured after wearing $ChromaGen^{TM}$ for 3 months. The results showed improvement reading ability of 3.70${\pm}$0.29 (p=0.01, t=2.26), 4.50%${\pm}$0.10 (p=0.01, t=2.78) for $ChromaGen^{TM}$ wearer with statistical difference. A survey on the satisfaction of reading improvement with wearing $ChromaGen^{TM}$ showed that 88.4% of questioned person answered wearing $ChromaGen^{TM}$ had improved their dyslexia symptoms. Conclusions: With statisical significance (p<0.05). this study suggests that $ChromaGen^{TM}$ lens has an effect on improving reading speed of dyslexia patient. We know from these results that the $ChromaGen^{TM}$ lens which is used to dyslexia had an effect to improvement of reading speed for dyslexia.

Purpose: The present study was conducted to analyze any difference in the movement of aspheric RGP lens by the amounts of keratometiric astigmatisms using keratometer and corneal topography. Methods: Corneal curvatures in thirty six eyes of males and females of with-the-rule keratometric astigmatisms in their twenties were measured by a keratometer and worn aspheric RGP lenses. Then, lens rotations, vertical and horizontal movements of lens by blinking were measured to compare with lens movements when aspheric RGP lenses were fitted by total keratometric astigmatisms using corneal topography. Results: The case having higher amount of central keratometric astigmatism was 61.1% of subjects, however, 36.1% of subjects showed higher total keratometric astigmatism indicating that central keratometric astigmatism was not always bigger than total keratometric astigmatism. Since over 0.25 diopter difference between total and central keratometric astigmatisms was shown in 19 eyes (52.8% of subjects), the prescription for lens fitting could be changed. Significant difference in horizontal movement was detected with increase of astigmatism when it compared based on the amount of keratometric astigmatism measured by a keratometer. However, there was no significant difference in lens rotation, horizontal and vertical movements by comparison with the amount of total keratometric astigmatism using a corneal topography. When central keratometric astigmatism measured by keratometer was bigger than total keratometric astigmatism estimated by corneal topography, bigger lens rotation was shown compared with opposite case. Also, the tendency of bigger lens rotation was measured with the increase of keratomatric astigmatism in the case of same prescription having same base curves with same amount of keratometric astigmatism but different curvatures. Conclusions: From the present study, we concluded that lens movements on cornea were not totally different when aspheric RGP lens fitted on with-the-rule astigmatism by keratometer and corneal topography. However, there was some difference in certain lens movements. Therefore, we concluded that further study on the relationship between the prescriptions for lens fitting should be conducted for improving the rate of successful lens fitting by keratometer or for the proper application of corneal topography for lens fitting.

Purpose: The aim of this study was to investigate the effect of improving read speed with color filter or without color filter to improve reading disorder of teenager who were diagnosed as Meares-Irlen syndrome through survey inspection with Meares-Irlen syndrome visual stress (MISViS) score. Methods: MISViS subjects were selected from screening survey MISViS results given above 2.13 in the clinical criteria scores (MISViS score). Reading speed were measured quickly and efficiently the rate of reading via test in which randomly ordered common words are read aloud during a minute. Each of the subjects were worn a filter of the lowest concentration in each color filter group composed of 15 groups. Results: MISViS score of MISViS group and control group were 2.57 and 0.66, respectively. Results of reading speed with filter and without filter in MISViS group were $102.27{\pm}27.86$ wpm and $118.87{\pm}26.99$ wpm (p=0.001), respectively, as well as were $132.93{\pm}6.88$ wpm and $133.43{\pm}6.64$ wpm (p=0.131) in the normal group. Associated with error changes with filter and without filter between two groups, skipping in MISViS Group were from $0.25{\pm}0.62$ times to 0 times (p=0.191), Errors were from $1.83{\pm}1.69$ times to $0.17{\pm}0.38$ times (p = 0.004) and, repetitions were 0. skipping in control group were 0 times, errors were from $0.21{\pm}0.43$ times to $0.07{\pm}0.27$ times (p=0.336) and, repetitions were from $0.14{\pm}0.36$ times to 0 (p=0.165). The filter of blue series chosen in MISViS group had higher percentage (40%), whereas, subjects in normal group were more likely to prefer the filter of gray color (29%). Conclusions: This study showed that MISViS score have been used as a significant diagnosis for Irlen syndrome screening. This study found that wearing suitable color filter for MISViS patients were useful to improve learning with regard to reading. Unique color filter selection for MISViS subjects must be carefully considered since fit color filter are different personally.

CRM refers to the operating activities that always maintain and promote good relationship with customers to ultimately maximize the company's profits by understanding the value of customers to meet their demands, establishing a strategy which may maximize the Life Time Value and successfully operating the business by integrating the customer management processes. In our country, many big businesses are introducing CRM initiatively to use it in marketing strategy however, most medium and small sized companies do not understand CRM clearly or they feel difficult to introduce it due to huge investment needed. This study is intended to present CRM promotion strategy and activities plan fit for the medium and small sized companies by analyzing the success factors of the leading companies those have already executed CRM by surveying the precedents to make the distributors out of the industries have close relation with consumers to overcome their weakness in scale and strengthen their competitiveness in such a rapidly changing and fiercely competing market. There are 5 stages to build CRM such as the recognition of the needs of CRM establishment, the establishment of CRM integrated database, the establishment of customer analysis and marketing strategy through data mining, the practical use of customer analysis through data mining and the implementation of response analysis and close loop process. Through the case study of leading companies, CRM is needed in types of businesses where the companies constantly contact their customers. To meet their needs, they assertively analyze their customer information. Through this, they develop their own CRM programs personalized for their customers to provide high quality service products. For customers helping them make profits, the VIP marketing strategy is conducted to keep the customers from breaking their relationships with the companies. Through continuous management, CRM should be executed. In other words, through customer segmentation, the profitability for the customers should be maximized. The maximization of the profitability for the customers is the key to CRM. These are the success factors of the CRM of the distributors in Korea. Firstly, the top management's will power for CS management is needed. Secondly, the culture across the company should be made to respect the customers. Thirdly, specialized customer management and CRM workers should be trained. Fourthly, CRM behaviors should be developed for the whole staff members. Fifthly, CRM should be carried out through systematic cooperation between related departments. To make use of the case study for CRM, the company should understand the customer and establish customer management programs to set the optimal CRM strategy and continuously pursue it according to a long-term plan. For this, according to collected information and customer data, customers should be segmented and the responsive customer system should be designed according to the differentiated strategy according to the class of the customers. In terms of the future CRM, integrated CRM is essential where the customer information gathers together in one place. As the degree of customers' expectation increases a lot, the effective way to meet the customers' expectation should be pursued. As the IT technology improved rapidly, RFID (Radio Frequency Identification) appears. On a real-time basis, information about products and customers is obtained massively in a very short time. A strategy for successful CRM promotion should be improving the organizations in charge of contacting customers, re-planning the customer management processes and establishing the integrated system with the marketing strategy to keep good relation with the customers according to a long-term plan and a proper method suitable to the market conditions and run a company-wide program. In addition, a CRM program should be continuously improved and complemented to meet the company's characteristics. Especially, a strategy for successful CRM for the medium and small sized distributors should be as follows. First, they should change their existing recognition in CRM and keep in-depth care for the customers. Second, they should benchmark the techniques of CRM from the leading companies and find out success points to use. Third, they should seek some methods best suited for their particular conditions by achieving the ideas combining their own strong points with marketing. Fourth, a CRM model should be developed that will promote relationship with individual customers just like the precedents of small sized businesses in Switzerland through small but noticeable events.

Purpose: The purpose of this study was to determine how many of our patients who had had anterior cruciate ligament (ACL) reconstruction returned to their previous levels of sports and to identify why not doing so. Material and Methods: We evaluated 43 knees with a minimum of two years follow-up among whom undergoing 109 ACL reconstruction from September 2003. The mean age of patients was 26 years (17 to 45 years) Clinical results was evaluated according to the Lysholm Knee scores, Tegner activity score, subjective IKDC questionnaires, objective IKDC evaluation form and KT-1000 arthrometer. Results: The overall clinical results demonstrated significant improvement at the final follow-up comparing to preoperative data (P<0.05). Among 43 patients, 25 patients (58%) returned to their previous level of sports and 18 patients (42%) did not. Of whom, 11 patients (61%) were not able to return to sports due to fear to re-injury and 7 patients (39%) suffered from instability and pain. The differences in the Lysholm Scores, KT-1000 arthrometer and subjective IKDC in the 3 groups of patients by ANOVA test were found to be statistically significant (P<0.001). Although there is no difference in objective IKDC and KT-1000 arthrometer, the difference was observed in Tegner activities, subjective IKDC obtained by those who returned to sport and those who had fear to reinjury (P<0.001). Conclusion: This study showed that a quater of patients could not return to their previous level of sport after ACL reconstruction because of fear to reinjury. We thought that not only improving the technique of ACL reconstruction and systemic rehabilitation but also considering psychological factor of patients could allow more patients to return to the previous level of sports.

Objectives : This study was designed to investigate the prevalence of depressive symptoms in patients with breast cancer and to identify demographic variables and clinical characteristics impact on depressive symptoms and health related quality of life in patients with breast cancer in a university hospital. Methods : Fourty-one patients with breast cancer were selected, who had visited the department of General surgery of the Wonkwang University hospital with a diagnosis of breast cancer regularly during the period November, 2010-May, 2011. All of subjects were evaluated for the depression, anxiety and the health related quality of life with Beck Depression Inventory(BDI), anxiety subscale of Personality Assessment Inventory(PAI) and Short-Form 36 Health Survey-Korean version(SF-36-K). Patients were divided into depressive symptoms and non-depressive symptoms group according to the BDI score. We compared SF-36-K between two groups, and analized multiple regression with depression and health related quality of life as criterion variables and demographic and clinical characteristics. Results : The prevalence of depression in patients with breast cancer in a University hospital was 36.4%. Compared to the non-depression, depressed patients with breast cancer appeared significantly lower mean scores on six subscales in SF-36-K : Physical function(p<.01), Role-physical(p<.001), General health(p<.05), Social function(p<.001), Role-emotional(p<.001) and Mental health(p<.001). But there was no significant difference between two groups in Vitality and Bodily pain. Anxiety, level of education and presence of enforcement of chemotherapy(63.6%) were significant explanation variables for depressive symptoms. And type of surgery and age(55.8%) were significant explanation variables for health related quality of life. Conclusions : The prevalence of depressive symptoms in patients with breast cancer in a University hospital was 36%. The depressive symptoms had not only negative impact on the health related quality of life but also important explanation variable for health related quality of life. These results suggest that depressive symptoms in patients with breast cancer should be evaluated and treated for improving patient's health related quality of life.

In the age of globalization, effective and efficient corporate management is becoming more important as domestic and international business circumstances changes. In the middle of endless changes in business circumstances, fast reaction to customers and market, and offering customized goods and service became essential. In this respect, CRM designed to utilize customer information scientifically and systematically, has become an essential system and marketing strategy to enhance corporate competitiveness. CRM has placed the importance of customers in the front of marketing and has focused every process and business minds on customers. Recent change in the market and the trend of establishing and introducing CRM system has lead us to concentrate on the introduction of CRM in the financial institutions. This study searched for several views about CRM in academic and industrial papers. Through theoretical approach on CRM, the background of the introduction of CRM, the purpose of CRM, the characteristic and application of CRM, and the expected effect of CRM will be discussed. This study is focused on financial institutions where CRM is widely used. And through documents about examples of the introduction of CRM, the status of the establishment of domestic CRM and the necessity and trend of CRM will be discussed. Also the problem of CRM in the financial institutions and the improvement of CRM in domestic banks will be analyzed. When discussing CRM in the financial area, customers are the main source of corporate profit and through relationship management with the customers enhancing loyalty and maximizing profit can be obtained. Especially in CRM in financial institutions, maintaining existing customers makes higher profit ratio, so repurchasing and cross selling becomes important for obtaining lifetime value of existing customers who contribute to most of the profit of corporations. As a result, CRM should be completely customer oriented. CRM in financial institutions is not merely marketing work, but organizational competence which is made up of standardized work process through total process integration inside the corporation. Corporations which plan to introduce CRM should analyze the characteristics and conditions of corporations and establish purpose and strategy of CRM. And they need long term view to find out the factors which best fit for the introduction of CRM. To enable this, strategy composed of daily marketing activity and CRM concept is necessary. Also continued improvement through drill and training for operating organization should be followed to maintain CRM well. And corporate culture must settle customer as the center of corporate value. The race for introducing and improving CRM has already begun. CRM should not be regarded as a choice. It should be accepted as something essential. In this reality financial institutions should solve subdivision problem of customers and necessity of customers with the mind of 'customer's profit is my profit'. Customer focused management should not be emphasized only by words. Efforts like viewing from the customer's point must be nurtured to provide methods to help customers. That is, we should not just follow what is done in foreign countries. We should solve the problem of our customers according to the situation of our country, our industry, our corporation. Then we can gain the trust of customers, and the value derived from the customers will become the background of CRM which will lead the corporation to success.

Purpose: The purpose of this study is to improve the reduction of coverage of PTVs adjacent to organ at risk (OAR) by setting up overlapping Planning Target Volume (PTV) during Volumetric Modulated Arc Therapy(VMAT). Materials and Methods: In patients who received Whole Brain, Gall Bladder and Rectum radiation therapy, We compared the cover change, maximum dose, Homogenicity Index and Conformity Index of PTV and also compared the maximum dose and average dose change of Organ At Risk by organizing treatment plans that are not applied overlaped PTV and treatment plans that are applied overlaped PTV in areas where coverage is insufficient. Results: overage of treatment plans with overlapping PTVs was increased in all patients, and overall coverage was also increased in each of the four patients. The maximum dose for PTV was increased in five patients, and the Homogenicity Index and Conformity Index for all patients did not differ much. The maximum dose of the lens was increased by 1.12 times, and the maximum dose was decreased in two patients for brain stem. The mean dose of the eyeball was increased by a maximum of 1.15 times, and there was no significant difference between both parotid gland. In case of gallbladder cancer patients, the mean dose in the liver and colon was decreased, and the mean dose in the duodenum was increased. In the case of rectal cancer patients, the mean dose was reduced for both femur and bladder set as OARs. The overall MU was shown to be similar in four patients, excluding one. Conclusion: If the critical dose of OAR is considered and used properly, I think it is a useful way to improve coverage of PTV.

As multimedia information recently increases fast, various types of retrieval of multimedia data are becoming issues of great importance. For the efficient multimedia data processing, semantics based retrieval techniques are required that can extract the meaning contents of multimedia data. Existing retrieval methods of multimedia data are annotation-based retrieval, feature-based retrieval and annotation and feature integration based retrieval. These systems take annotator a lot of efforts and time and we should perform complicated calculation for feature extraction. In addition. created data have shortcomings that we should go through static search that do not change. Also, user-friendly and semantic searching techniques are not supported. This paper proposes to develop S-MARS(Semantic Metadata-based Multimedia Annotation and Retrieval System) which can represent and extract multimedia data efficiently using MPEG-7. The system provides a graphical user interface for annotating, searching, and browsing multimedia data. It is implemented on the basis of the semantic metadata model to represent multimedia information. The semantic metadata about multimedia data is organized on the basis of multimedia description schema using XML schema that basically comply with the MPEG-7 standard. In conclusion. the proposed scheme can be easily implemented on any multimedia platforms supporting XML technology. It can be utilized to enable efficient semantic metadata sharing between systems, and it will contribute to improving the retrieval correctness and the user's satisfaction on embedding based multimedia retrieval algorithm method.

1. Objectives: Though the eating habits have improved and the living method has become convenient according to the economic growth thanks to the modern industrialization, because of the lack of exercise, obesity, wrong eating habits and stress etc, various symptoms of disease of adults are on the rise. This is the phenomenon that happens as the eating life has become life in the West along with the inundation of the western culture in our society. In this perspective, there has been many various clinical research that's been proceeded so far about the physical constitution and obesity, but there has been little research on the objective analysis of the clinical research about the alimentotherapy using taeeumjoweetang. 2. Methods: In this research we have checked the weights, fat rates, fat weight, abdominal fat rate, blood pressure, and BMI over the objects of the women that were diagnosed as lunisolar system as their physical constitution, and assessed the paramecium lipid, in-blood antioxidation enzyme and the damage of oxidization in the urine by physical constitution-specific of the body shapes that were determined by BMI. The statistical analysis of the current research was processed by using of SPSS 17.0 program. We have figure out statistical amounts such as the arithmetic average, average deviation rate and percentage number. Fro the verification of he significancy of each elements, we have used the paired t-test, ANOVA, Chi-square test at the level of p<0.05. 3. Results and Conclusions: Their characteristics are age $21.20{\pm}1.35$, height $160.30{\pm}6.11cm$, weight $64.66{\pm}8.72kg$, fat rates are $35.97{\pm}4.87%$, fat amount $23.40{\pm}5.48$, abdominal fat rate $0.823{\pm}0.03$, BMI $25.12{\pm}2.79kg/m^2$, and systolic blood pressure $111.60{\pm}10.28mmHg$ and diastolic blood pressure $68.60{\pm}7.43mmHg$ and we have let them take the medicine twice a day for 8 weeks. The clinical result for the Cholesterol, Triglyceride, HDL-cholesterol, LDL-cholesterol, SGOT, SGPT, of the object people was that for the function of the liver, the result of the SGOT and SGPT test was $17.16{\pm}3.05$, $15.00{\pm}2.99IU/L$, which was a decrease, and had statistical meaning, but for the SGOT, though the figure reduced to $11.92{\pm}4.61$, $10.80{\pm}3.07$, it had no statistical meaning. For the whole cholesterol level, the figure reduced to $169.00{\pm}19.95$, $160.08{\pm}22.52$ mg/dL and had statistical significance(p<0.05). Neuter fat number, Triglyceride has slightly increased to $67.52{\pm}36.32$, $68.08{\pm}47.33$ mg/dL but did not have any statistical meaning. The antioxdant enzyme marker standard marker, SOD has increased to $2.52{\pm}0.73$, $2.86{\pm}0.60U/ml$, and had statistical significance(p<0.01). Catalase also increased by $0.63{\pm}0.18$, $1.07{\pm}0.25mmol/ml$ and had statistical meaning(p<0.01). GPx also increased to $204.76{\pm}32.64$ nmol/ml and had statistical meaning(p<0.01). But, for the Total antioxidant, though it has raised to $1.51{\pm}0.26$, $1.57{\pm}0.17nmol/{\mu}l$, it did not have any statistical meaning. MDA of oxidative stress marker has decreased to $1.70{\pm}0.68{\mu}g/ml$, $1.21{\pm}0.50{\mu}g/m$ and had statistical significance(p<0.01). 8-OHdG also decreased $3.35{\pm}0.95ng/ml$, $2.21{\pm}0.50ng/ml$ and had statistical meaning(p<0.01). In this research, we have analyzed the various markers relating to BFM and changes in oxidative enzyme in blood by takingtaeeumjoweetang. Taeeumjoweetang has the positive effect on inbody antioxidant system and reducing the content of cholesterol, which is proven to help losing weight and improving hyperlipidemia statistically. With this research, we hope to improve the lifestyle of those who are either obese or need to manage their dietary habits, and also to become the touchstone of integrating Oriental Medicine with the science of food & nutrition.
