The insurance industry is highly competitive since it is difficult to differentiate one company's service from another. This paper examines how Ankuk Fire & Marine Insurance has differentiated its service and improved its competitive edge against others by using electronic data interchange (EDI). In order to improve its service level, Ankuk Fire Insurance has significantly reduced paper work by transmitting information electronically to its customers. This was possible with standardized product codes and databases which were installed both on the Ankuk and customer premises. Ankuk Fire Insurance transmits its customer's insurance information to the customer's database instead of hand-carrying or mailing it. The main benefits of this has been: (1) fewer errors as data does not need to be re-entered, (2) faster customer service with electronic data delivery, and (3) better quality customer service due to highly structured relationships with customers. EDI will soon be available to all insurance companies due to the goverment's aggressive promotion of a KTNet plan. Ankuk Insurance, therefore, needs to adopt the standardized protocol recommended by KTNet and develop new products which will give them a competitive edge and minimize the possibilities of losing their clients to other insurance firms.

Purpose: This study aims to examine differences in experiences of violence and hospital violence attitude according to gender and gender-role identity of clinical nurses. Methods: The quota sampling method, was used to select the research subjects. They were divided into two groups male and female nurses who worked for three general hospitals or higher level-hospitals in Incheon and Gyeongbuk. The data of 219 subjects was used for final analysis. The IBM SPSS 22.0 was used to analyze the data t-test and ANOVA. Results: According to gender, the hospital violence experience of female nurses was oserved frequently when the verbal violence came from guardians, and when the physical threats came from others. For male nurses, the experiences of hospital violence was obserbed. According to gender, the hospital violence attitude revealed significant differences in female nurses that the negative attitude was higher (t=-4.69, p<.001). According to gender-role identity, the undifferentiated and femininity showed significant differences (F=4.86 p=.003). Conclusion: The differentiated strategies of coping measures and violence preventive education considering the gender and gender-role identity of clinical nurses would help formulate measures for the effective management of hospital violence.

CDH-13(T-cadherin), which is one of a kind among the 20 cadherins, can be found mainly in wall of aorta, neuron, spleen, blood vessel etc. It is also called H-cadherin. This structural difference can explain that CDH-13 is thought to play a key role in maintaining mutual relation between extra and intra-cellular environment rather than in cell adhesion. The main function of CDH-13 is to participate in blood vessel function. Additionally, it is known to regulate cell growth and cell contact inhibition. When cells are proliferating, cell surface perceives other cells so that substance such as CDH-13 can inhibit their growth or proliferation resulting in homeostasis without endless proliferation or invasion of connective tissue boundaries. However, tumor cell itself appears to be different from normal cells' growth, invasion or transmission. Therefore, it can be diagnosed that these characteristics are closely related to expression of CDH-13 in tumor cells. This study is to investigate expression of CDH-13 in SCC and its correlation with promoter methylation. 20 of tissue species for the study are excised and gathered from 20 patients who are diagnosed as SCC in department of OMS, dental hospital, dankook university. To find development of CDH-13 in each tissue samples, immunohistochemical staining, RT-PCR gene analysis and methylation specific PCR are processed. The results are as follows. 1.Immunohistochemical staining: In normal oral squamous epithelial tissue, strong expression of CDH-13 was found in cell plasma membrane of basal cell layer. On the other hand, in case of low-differentiated oral SCC, development of CDH-13 was hardly seen. 2.The development of CDH-13 gene: In 9 of samples, expression of CDH-13 gene could be seen and 2 of them showed low expression compared to the others. And rest of the 11 samples showed no expression of CDH-13 gene. 3.Methylation of CDH-13 gene: Among 9 samples which expressed CDH-13 gene, 7 of them showed unmethylation. In addition, among 11 samples without CDH-13 gene expression, 10 showed methylation. According to the results stated above, promoter methylation were found in 13 samples(65%) among 20 of oral SCC samples. In low-differentiated SCC, suppression of gene expression could be seen accompanying promoter methylation. These phenomenon of gene expression was proved by immunohistochemical investigation. Finally, for development of oral SCC, conclusions can be made that suppression of CDH-13 played a main role and suppression of gene expression was originated from promoter methylation. Considering this, it is expected that suppression of CDH-13 from promoter methylation to be utilized as a good diagnostic marker of oral SCC.

Radioactive iodine($^{131}I$) treatment reduces recurrence and increases survival in patients with differentiated thyroid cancer. However, it is important in terms of radiation safety management to measure the radiation dose rate generated from the patient because the radiation emitted from the patient may cause the exposure. Research methods, it measured radiation dose-rate according to the elapsed time from 1 m from the upper abdomen of the patient by intake of radioactive iodine. Directly comparing the changes over time, high dose rate sensitivity and efficiency is statistically significant, and higher chamber than GM counter(p<0.05). Low dose rate sensitivity and efficiency in the chamber had lower levels than gm counter, but not statistically significant(p>0.05). In this study confirmed the characteristics of calibrated ionization chamber and GM counter according to the radiation intensity during high-dose radioactive iodine therapy by measuring the accurate and rapid radiation dose rate to the patient explains, discharged patients will be reduced to worry about radiation hazard of family and others person.

Objectives : The purpose of this study was to examine factors related to the satisfaction level of patients with dental services. Methods : The subjects in this study were 200 patients at three different dental clinics in South Gyeongsang Province, on whom a survey was conducted from June 1 to July 31, 2009. The collected data were analyzed, and the findings of the study were as follows. Results : In regard to the general characteristics of the patients investigated, the women(61.5%) out-numbered the men. By age, those who were at the age of 30 and down made up the largest age group(47.0%). By academic background, the greatest group received junior-college education(54.0%). By occupation, the company employees constituted the largest group (50.5%). By income, the greatest group earned an income of 2 to 2.99 million won(75.0%). Second, as to connections between the characteristics of dental treatment and the reason of choosing the dental clinics, the largest group(70.4%) chose the dental clinics by word of mouth or the recommendation of others. Concerning the reason of dissatisfaction, the biggest group(72.7%) was unsatisfied with medical costs. As for the degree of explicit complaint, the greatest group(49.7%) sort of complained about what made them dissatisfied. Regarding the type of treatment, the biggest group(49.0%) received prosthodontic treatment. In relation to fear for dental treatment, the largest group(34.0%) feared receiving the treatment, and the biggest group(42.6%) did that due to the sound of machines. Third, satisfaction with services(0.762) had the closest correlation to overall satisfaction level, followed by satisfaction with employees(0.735), satisfaction with dentists(0.644) and satisfaction with convenient facilities (0.579). Fourth, the factors that affected overall satisfaction level were gender, the reason of choosing the dental clinic, satisfaction with dentists, satisfaction with employees, satisfaction with services and satisfaction with convenient facilities. The patients who were better satisfied with services(p<0.001), who were more contented with dentists(p<0.001), who chose the dental clinics by the recommendation of others(p<0.01), who were male(p<0.05), who were more gratified with employees(p<0.05) and who were more contented with convenient facilities expressed better overall satisfaction. Conclusions : The above-mentioned findings suggested that dental institutions should keep track of the expectations of patients to prepare differentiated strategies for marketing and human-resources development in consideration of their own circumstances to boost the satisfaction level of patients. Specifically, it's required to heighten the satisfaction level of patients with dentists.

Standards boost technological innovation by promoting information sharing, compatibility, stability and quality. Identifying groups of companies that particularly benefit from these functions of standards in their technological innovation and commercialization helps to customize planning and implementation of standards-related policies for demand groups. For this purpose, this study engages in profiling of SMEs whose R&D objective is to respond to standards as well as those who need to implement standards system for technological commercialization. Then it suggests a prediction model that can distinguish such companies from others. To this end, decision tree analysis is conducted for profiling of characteristics of subject SMEs through data mining. Subject SMEs include (1) those that engage in R&D to respond to standards (Group1) or (2) those in need of product standard or technological certification policies for commercialization purposes (Group 2). Then the study proposes a prediction model that can distinguish Groups 1 and 2 from others based on several variables by adopting discriminant analysis. The practicality of discriminant formula is statistically verified. The study suggests that Group 1 companies are distinguished in variables such as time spent on R&D planning, KoreanStandardIndustryClassification (KSIC) category, number of employees and novelty of technologies. Profiling result of Group 2 companies suggests that they are differentiated in variables such as KSIC category, major clients of the companies, time spent on R&D and ability to test and verify their technologies. The prediction model proposed herein is designed based on the outcomes of profiling and discriminant analysis. Its purpose is to serve in the planning or implementation processes of standards-related policies through providing objective information on companies in need of relevant support and thereby to enhance overall success rate of standards-related projects.

The aim of this study was investigating the consumers' and apparel firm worker's awareness and reliability of the environmental friendly textile materials. The subjects of the questionnaire survey were general consumers(n=235) and workers at Korean apparel firms(n=236). The questionnaire was developed to measure the awareness and reliability on nine environmental friendly textile materials. The results showed that general consumers had a higher reliability on the function of the environmental friendly materials but had a lower awareness than the workers at the apparel firms. Women and subjects, who experienced in purchasing the environmental friendly products, had higher awareness and reliability of the environmental friendly textile materials than others. The workers at apparel firms had higher awareness of the environmental friendly textile materials than the general consumers, but the reliability on the function of the materials was relatively low. The reliability and awareness differed by the firms' major products and their jobs. The workers at the children's clothing firms and sportswear firms had higher level of awareness about the environmental friendly textile than the workers at the casual-wear firms. The workers' awareness on environmental friendly textile materials was differentiated by their jobs. The product developers and material buyers had higher awareness on the environmental friendly textiles compare to the workers of the sales or marketing division. These results imply that promoting environmental friendly textile material to the sales person is needed in order to increase the sales volume of the products.

We need to seek after new direction and order of design that puts more value on the spirits and culture of human beings in the 21st century, creating a new, all-inclusive value in which individual human being, the society and the environment can co-exist in a peaceful relationship by overcoming the materialistic, analytical, competitive, and differentiated values of traditional industrial society. The aim of this study, then, is to present a new method of design that can meet the demands of the 21st century in a civic age of information, knowledge and culture, by focusing on Monistic ideals derived from a deeply rooted Oriental philosophy. The concept of Monism is embodied by a mind set that treasures the benefit to others over rewards to the self, puts more importance on the spiritual life hidden behind physical phenomena, thinks more of what lacks than what exceeds, elevates the mind over the body, and seeks after beauty via a total harmony of balance and development that can be feasible only by combining all these elements. Ultimately, the new design principle based on the Monism consists of three basic elements: (1) identification of the subject and the object between things under the perception that all things are one (Unification); (2) the ability that helps things exist with appropriate beauty maintaining balance and stability (Harmony); and (3) the attitude of sharing to maintain sustainable vitality by filling up what lacks or is missing in a whole(Change).

Objectives: Although increased reactive oxygen species (ROS) is caused by stress accelerates collagen degradation, there was no data on the relationship between stress and urinary hydroxyproline (Hyp) and proline (Pro), a good marker of collagen degradation. The purpose of this study was to evaluate the relationship between depression, anxiety, and stress (DAS) and concentrations of urinary Hyp and Pro. Methods: 97 hospital employees aged 20 to 58 were asked to fill out comprehensive self-administrated questionnaires containing information about their medical history, lifestyle, length of the work year, shit-work and DAS. Depression Anxiety Stress Scale (DASS) was applied to evaluate chronic mental disorders. Urine samples were analyzed using High Performance Liquid Chromatography (HPLC) with double derivatization for the assay of hydroxyproline and proline. Results: The mean value of Hyp and Pro concenturation in all subjects was $194.1{\pm}113.4\;{\mu}mol/g$ and $568.2{\pm}310.7\;{\mu}mol/g$. DASS values and urinary Pro concentrations were differentiated by sex (female > male, p < 0.05) and type of job (nurse > others, p < 0.05). In the stepwise multiple linear regressions, urinary Hyp and Pro concentrations were influenced by stress (Adjusted $r^2$ = 0.051) and anxiety and job (Adjusted $r^2$ = 0.199), respectively. Conclusions: We found that stress and anxiety were correlated with urinary Hyp and Pro concentrations. To identifying a definite correlation, further study in large populations will be needed.
