Objective : Atypical and malignant meningiomas(AM, MM) are known to be rare and show aggressive behavior. Limited data are available concerning the clinical features, effectiveness of surgical removal and role of radiation therapy with AM, MM. The authors report our experience of AM, MM, with respect to clinical features. Methods : Twenty-four cases of AM and 28 cases of MM, who were operated between 1988 and 1999 were retro-spectively studied review of medical records and radiological findings. These were compared with control group of 24 cases of menigiomas manifestating usual clinical course, which are selected arbitrarily among operative cases between Apr. 1999 and Dec. 1999. Mean follow-up periods were 26(1-91) months for AM and 23(1-62) for MM. Authors analyzed the prognostic factors for survival, and statistical analysis were accomplished by Kaplan-Meier method and log-rank test. Results : Differences of clinical features between control groups and these atypical and malignant meningioma group were not significant. However, the location of MM was frequent in non-basal area(p<0.01). In AM, there were 4 patients of recurrence, and 3 patients of mortality. Among mortality cases, only one patient died of tumor progression, the other patients died of other causes. The survival at 2 year and 5 year in this group were 88% and 74% respectively, and in MM, 11 patients died due to tumor progression and 2 had spinal metastasis. The survival at 2 year and 5 year were 72% and 20%, respectively. For extent of resection, total removal(Simpson grade 1 or 2) was less often achieved in MM compared with AM(50% vs. 83%). Extent of resection of tumor and postoperative radiation therapy did not affect survival in both AM, MM. Conclusions : Clinical behavior of AM showed more benign than that of MM. Prognostic factor for survival is not related extent of resection of tumor and postoperative radiation therapy. However, further investigation with long-term follow-up and additional cases is mandatory.

This study analyzed the factors related to the job satisfaction and turnover rate of students in the skin care contract department, and suggested ways to enhance long-term employee retention. Frequency analysis and multiple regression analysis were performed using the SPSS statistical program and based on the survey data of 260 skin care contract students. The main results were as follows. First, contract students had high job satisfaction because of sufficient in-service training during the internship and also received the authority to perform the job duties of their positions. Second, the regular technical education for the job of contract students gave them confidence in job performance and job confidence, which led to long-term employee retention. Third, contractual students' turnover was reduced by applying compensation such as incentives, awards, and promotion opportunities in accordance with their work performance. Therefore, the results of the study suggest that compensation based on job performance, and the confidence in job performance of skin care contract students, can lead to increased job satisfaction, a reduced turnover rate and better long-term employee retention.

Purpose - Recently, although corporate social responsibility activities have been increasing in size, they do not have to achieve qualitative improvements and can be passive and cost consuming. Therefore, companies should make quantitative as well as qualitative improvements in their efforts in corporate social responsibility activities. In this study, the classification of social responsibility activities in a variety of studies was analyzed through a more specific path than in previous studies. Corporate behavior image, social behavior image, and corporate contributions image were analyzed through a more detailed analysis of performance. This study suggests that more detailed and concentrated social responsibility activities be pursued by forming companies. Research design, data, and methodology - The purpose of study is to gauge the corporate need for a more intensive, specific area of CSR activities. For this purpose, the sample of consumers that were targeted for CSR activities, recognized as 261 persons, have been investigated. Through a theoretical discussion on previous research, nine hypotheses were established on corporate image, the influence of corporate performance on CSR, and the CSV regulation effect. In order to test the hypothesis, a survey was conducted on 261 male and female consumers who were targeted for CSR, being persons in their 20s to 40s. PASW Statistics 18.0 and AMOS 18.0 were used for statistical analysis. Results - Corporate behavior image was formed through legal responsibility activities and economic responsibility activities. In addition to economic responsibilities, ethical responsibilities and environmental responsibilities were confirmed to have influence on social behavior image. Corporate social responsibility and philanthropic responsibility were confirmed to have influence on economic contribution image. Corporate image has positive effects on brand attitude, corporate reputation, and corporate competition. In addition, when CSV awareness is high, consumers perceive corporate image only through economic responsibility. However, when CSV awareness is low, economic responsibility as well as legal responsibility through charitable activities form the corporate image that influences the brand attitude and corporate reputation, as well as corporate competitiveness. It would appear that the area of corporate social responsibility needs more intensive management for corporate image and corporate competitive advantage. Conclusion - First, the findings of this study show that each CSR activity has a different effect on corporate image and thus, the corporate image influences corporate performance in distinct ways, depending on the CSR activity. This implies that reactive strategies should be tailored to the required image. Second, there is a difference in CSV awareness between groups. When the CSV awareness is low, we can confirm that legal responsibility activities have an especially significant effect on corporate image, implying that corporations should pursue their economic objectives within legal regulations and need to invest significant time and effort for this. This study has limited generalization potential because the result of the model fit has insufficient reference value. In future research, we need to approach various dimensions of corporate performance.

Purpose - This study identifies relationships amongst repurchase intentions, brand equity, and preference by applying VMD of fashion retail stores. The results would help coffee shop owners and coffee makers in devising an appropriate strategy for successfully managing coffee shops. Research design, data, methodology - The VMD model of a coffee shop includes harmony, trend, and attractiveness, while brand equity encompasses brand awareness, perceived quality, and brand image. In this study, the VMD factors of coffee shops, brand equity, and brand preference, are shown as independent variables, while repurchase intention is shown as the dependent variable. The study aims to ascertain the extent of the influence configuration factors of a coffee shop have on brand equity, brand preference, and repurchase intention. Regression analysis was used to verify the mediating effects of brand preference on brand equity and repurchase intention. The measurement items were already deemed as reliable and valid in the previous study, but some modifications were made for the purposes of this study. Questionnaires were distributed to 550 consumers on a national scale, and 517 consumers amongst these were finally used as a sample for analysis using the SPSS 17.0 statistical program. Results - First, amongst the VMD configuration factors of a coffee shop, trend, and attractiveness have a positive impact on brand equity (brand awareness, perceived quality, and brand image). Second, brand equity has a positive effect on brand preference. Third, brand preference has a positive effect on repurchase intention. Fourth, brand preference plays the role of a mediator in measuring the impact of brand awareness and brand image on customers' repurchase intentions. Conclusions - The theoretical implications can be summarized as follows. First, this study proposes a theoretical basis that can be adapted to the VMD configuration factors of a coffee shop by identifying the relationship between brand equity and coffee shops. This study applies the VMD factors to the coffee shops and presents a new research model by examining the relationships amongst VMD components of coffee shops: brand equity, brand preference, and repurchase intention. Second, it clearly establishes the relationship between brand equity and brand preference by identifying the mediating effects of brand preference, given that brand equity has a positive impact on repurchase intention. The practical implications are as follows. First, development of brand equity and management can be important components for coffee shops in determining that the VMD configuration factors of coffee shops have an impact on brand equity. Second, amongst the VMD configuration factors, attractiveness and trend have a positive influence on choosing coffee shops, therefore store atmosphere should be attractively designed, while the menu and interiors should complement each other and be reviewed periodically to conform to the latest trend. Third, VMD configuration factors that are confirmed are not easily changed. Fourth, large franchises and foreign companies have strengths in scale, locations, and brand. Fifth, the different ways of campaigning should be compared to those of large franchises and foreign companies in order to increase brand equity using VMD configuration factors.

Objectives : The objective of this study is to estimate the economic costs of cancer on society. Methods : We estimated the economic burden of people with cancer in South Korea. To perform the analysis, we reviewed the records of people who were cancer patients and those who were newly diagnosed with cancer. The data was compiled from the National Health Insurance Corporation, which included the insurance claims database, a list of cancer patients, a database that records the cancer rates, the Korea Central Cancer Registry Center s cancer patient registry database and the Korea National Statistical Office s causes of death database. We classified the costs as related to cancer into direct costs and indirect costs, and we estimated each cost. Direct costs included both medical and non-medical care expenses and the indirect costs consisted of morbidity, mortality and the caregiver's time costs. Results : The total economic costs of cancer in South Korea stood at 14.1 trillion won in 2005. The largest amount of the cost 7.4 trillion won, was the mortality costs. Following this were the morbidity costs (3.2 trillion won), the medical care costs (2.2 trillion won), the non-medical care costs (1.1 trillion won) and the costs related to the caregiver's time (100 billion won). As a result, the economic cost of cancer to South Korea is estimated to be between 11.6 trillion won to 14.1 trillion won for the year 2005. Conclusions : We need to reduce the cancer burden through encouraging people to undergo early screening for cancer and curing it in the early stage of cancer, as well as implementing policies to actively prevent cancer.

Plant metabolomics is a research field for identifying all of the metabolites found in a certain plant cell, tissue, organ, or whole plant in a given time and conditions and for studying changes in metabolic profiling as time goes or conditions change. Metabolomics is one of the most recently developed omics for holistic approach to biology and is a kind of systems biology. Metabolomics or metabolite fingerprinting techniques usually involves collecting spectra of crude solvent extracts without purification and separation of pure compounds or not in standardized conditions. Therefore, that requires a high degree of reproducibility, which can be achieved by using a standardized method for sample preparation and data acquisition and analysis. In plant biology, metabolomics is applied for various research fields including rapid discrimination between plant species, cultivar and GM plants, metabolic evaluation of commercial food stocks and medicinal herbs, understanding various physiological, stress responses, and determination of gene functions. Recently, plant metabolomics is applied for characterization of gene function often in combination with transcriptomics by analyzing tagged mutants of the model plants of Arabidopsis and rice. The use of plant metabolomics combined by transcriptomics in functional genomics will be the challenge for the coming year. This review paper attempted to introduce current status and prospects of plant metabolomics research.

Objectives : Oral care is important for workers and Korean adults to improve the quality of life and perform economic activities. This study was conducted to prepare the basic data to establish the management system for adult oral health by looking into characteristics by ages and the genders questingly. Methods : Oral health examination was conducted on workers in 2009 in the city of Gwangju and Chonnam province. This analysis was extracted using SPSS(SPSS 12.0 for windows, SPSS Inc, Chicago, USA). Results : Among the study respondents, 39.5% workers and 47.7% Korean adults answered their subjective oral health is not good, but there was no statistically significant difference between them(p< $0.001^{***}$). 39.9% workers and 2 0.6% Korean adults were smokers, and they showed a statistically significance in the ages and genders (p< $0.001^{***}$). 91.2 %workers and 49.8% Korean adults brushed their teeth before going to bed, and they showed a statistically significance in the ages and genders(p< $0.001^{***}$). In terms of the gender, male workers and Korean female adults showed high frequency of use, and both workers and Korean adults aged 18-24 showed high frequency with regard to the age. Regarding the use of oral care items, 36.0% workers and 16.9% Korean adults used them, and a statistical significance was shown in both the gender and age(p< $0.001^{***}$). In terms of the gender, female workers and Korean female adults showed high frequency of use and in terms of the age, 45-54 age bracket workers and 30-34age bracket Korean adults used the items frequently. 28.0% workers and 30.7% Korean adults answered that their mastication among oral functions is uncomfortable, and 8.8% workers and 6.5% Korean adults responded that it is hard to pronounce. They were statistically significant in the gender and age(p< $0.001^{***}$). Workers and Korean female adults expressed their mastication discomfort and men expressed that they have a difficulty in pronouncing. In terms of the age, the 54-64 age bracket workers and Korean adults express their inconvenience of mastication and pronunciation. Conclusions : According to the above findings, it needs to build the economical and efficient adult oral health care system in order to enhance both workers and Korean adults' oral health.

Objectives : The purpose of this study is to evaluate the appearance of having relationship between the exposure to lead and cadmium and the dental caries targeting adults in the Republic of Korea. Methods : The study was designed as a cross-sectional study, using the data of the Fourth Korea National Health and Nutrition Examination Survey. The subjects as 1,966 people, who were confirmed the appearance of dental caries among 1,991 people of having been offered the heavy-metal concentration in blood. Statistical analysis was conducted using SPSS 19.0, according to complex sampling design. Results : As a result of multi-variate analysis on factors of dental caries, in Model I without correction, the gender, age, educational level, appearance of lifelong smoking, daily toothbrushing frequency, appearance of using dental floss, and subjective oral health status were recognized as important factors. In Model II with correction of gender and age, the educational level, daily toothbrushing frequency, and subjective oral health status were recognized as statistically significant factors. In Model III with correction of all factors, the gender, age, educational level, appearance of using dental floss, and subjective oral health status were functioning as statistically significant factors. As a result of statistically analyzing relationship between the exposure to lead and cadmium and the dental caries targeting adults, it was analyzed that there is no significant correlation. However, in case of lead, the tendency of being grown the cross ratio of dental caries could be examined in model I, which didn't correct disturbance factor, model II, which corrected gender and age, and model III, which corrected all variables of disturbance factor. Conclusions : The exposure to lead and cadmium was indicated to have no relationship with adults' dental caries. However, a continuous research of relationship was considered to be necessary by using Korea National Health and Nutrition Examination Survey, which is surveyed in the future.
