  • This study seeks to understand the effects of information search activities and brand image on the hotel patronage intention based on the theory of reasoned action. First, it investigates the influence of attitude formed about hotel on the patronage intention. Second, it seeks to develope an alternative to TRA by looking into the effects of hotel image variable on hotel-specific attitude and patronage intention and attempts to substantiate the role of brand image as a substitute to subjective norm to increase the TRA's explanatory power. The main finding of this study are as follow; First, out of the three components of cognitive evaluation of hotel (human service, physical service and information service), human and physicial services were found to have significant influence on patronage intention. Brand image was found to exert notable influence on attitude toward hotel as well as patronage intention. Remarkably, the finding that brand image positively enhanced the TRA model sheds new strategic insight as to the usefulness of brand image as an alternative to overcome the TRA's limitation stemming from subjective norm. Third, it was learned that study subjects gave more weight to external information sources such as TV, radio, newspaper, magazine, and internet than to internal sources such as individual knowledge, experience or self image.

  • Background: Myeloproliferative disorders (MPDs) are clonal hematologic malignancies originating at the level of the pluripotent hematopoietic stem cell. Matrix metalloproteases (MMPs) are proteolytic enzymes that contribute to all stages of malignancy progression. Genetic variants in the MMP genes may influence the biological function of these enzymes and change their role in carcinogenesis and progression. To our knowledge, this is the first investigation of associations between the -735 C/T and -1562 C/T polymorphisms in the MMP2 and MMP9 genes, respectively, and the risk of essential thrombocytosis (ET), and polycythemia vera (PV). Materials and Methods: The case-control study included JAK2V617F mutation positive 102 ET and PV patients and 111 controls. Polymorphisms were determined by using polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) and electrophoresis. Results: No statistically significant differences were detected between patient (ET+PV) and control groups regarding genotype distribution for MMP2 gene-735 C/T and MMP9 gene -1562 C/T polymorphisms and C/T allele frequency (p>0.050). Statistically borderline significance was observed between PV and control groups regarding genotype distribution for the MMP9 gene -1562 C/T polymorphism (p=0.050, OR=2.26, 95%Cl=0.99-5.16). Conclusions: Consequently this study supported that CC genotype of MMP9 gene -1562 C/T polymorphism may be related with PV even if with borderline significance.

  • Current leakage of industrial technologies with revealing state secret against nation is gradually increasing and scope of the spill is diversified from technology-oriented leakage to new economic security sector like information and communication, electrical and electronic, defense industry, illegal export of strategic material, economic order disturbance by foreign country, infringement of intellectual property, etc. So the spill damage can affect not only leaked company but also national interests and entire domestic industry. According to statistics from National Industrial Security Center of National Intelligence Service, a major cause of technology leakage is not only by external things about hacking and malignant code, but internal leakage of former and current employees account for about 80%. And technology leakage due to temptation of money and personal interests followed by technology leakage of subcontractor is steadily increased. Most studies in the field of security have tended to focus on measuring security capability of company in order to prevent leakage core assets or developing measurement Indicators for management rather than security activities of the company members that is most important. Therefore, this study analyzes the effect of most underlying security education in security activities on security capabilities of enterprise. As a result, it indicates that security education have a positive(+) correlation with security capabilities.

  • Abstract The purpose of this paper is to analyze production and innovation networks of manufacturers in the rural, long-live areas of Gangwon Jeju and to suggest an ideal regional development model of rural areas in the knowledge-based information age. For this purpose, we compared the areas of Gangwon Jeju with the long-live belt areas in the rural pan of the Honan region and Gwangju Jeonju, the urban part of Honam. The findings from the study are summarized as follows. Firstly, the stronger the local networks in terms of supply of the necessary input materials and labor, the more successful the manufacturing industry is in the given area. Secondly, the more diverse and lasting the networks (in terms of the location of manufacturers, local area and national area) and cooperation agents(businesses, research institutions, the local government, the central government) they have, the more prosperous the manufacturing industry is. These results indicate that the successful development model for rural areas requires that we take the approach of fostering potential innovation capabilities of total areas by fully utilizing their innate resources so as to create an internal cooperative network and further build extensive networks encompassing external entities to create a virtual innovation cluster.

  • The purpose of this study is to investigate the teaching methods of prediction, inference, and hypothesis. The major data source was gathered by in-depth interview of science teachers (about 50-80 minutes for each interview). The interviews were conducted using semi-structured interview protocol, which consisted of three major parts: (1) Teacher's definition of prediction, inferences, hypothesis, (2) Teaching methods of prediction, inferences, and hypothesis and (3)Reasons of teacher's inaccurate perceptions of prediction, inference, and hypothesis. All the interviews were audio-taped and transcribed. Topics in the questions were categorized. The results were as follows: Teachers recognized the importance of prediction, inferences, and hypothesis. But they didn't have an accurate conception and they have great difficulty in classifying and explaining the prediction, inferences, and hypothesis. To find out the teaching methods, researcher investigated the inquiry activities, teaching times, usage of terms, teachers' questions, and teaching difficulties. Reasons for having difficulty were lack of teaching competency, difficulties from the students, and problems in the present curriculum. Finally, we discovered that the reasons for teacher's inaccurate perceptions of prediction, inference, and hypothesis were two factors. One is internal factors, which include the lack of scientific inquiry process skills, burdens of science subject and lack of science education knowledge. The other is external factors, which include education system for evaluations and lack of teacher education. In conclusion, this study suggested establishing more elementary teacher education programs that include strengthened concepts of inquiry process skills and teaching methods.

  • This study aims to identify constructs of cultural competency specifically relevant to the Korean society and to test its reliability and validity among human service workers. For the purpose of the study, authors conducted focus group interviews and conferences with human service workers to draw the concept of cultural competency. Further, this study conducted to two separate pilot tests with 20 social workers with practice experiences in order to clarify descriptions and relevance of scale items. Based on the literature review on the concept of cultural competency and analysis of focus group interviews, 40 items were initially constructed and then were reduced to a 32-item scale after two separate pilot studies. Meantime, suggestions made by an advisory group were also reflected in the scale development process. Finally, one hundred ninety four workers in social service agencies were recruited to evaluate the relevance of the scale items in a 5 point Likert scale. Through exploratory and confirmatory factor analysis, 4 main factors were identified: 1) competency to use culturally relevant skills, 2) cultural awareness and sensitivity, 3) cultural knowledge, and 4) efforts to overcome cultural differences. These factors were consistent with sub-concepts of cultural competency in other studies. Confirmatory factor analysis also showed that the model fitness was at the high level and convergent analysis with the similar scale also showed high correlations. Internal consistency also remained at a high level. Based on the results, implication for social work practice and education were discussed.

  • In order to improve performances of submicrometer-sized Si negative electrode which shows larger volumetric change than nano-sized Si, composite binders are introduced by blending between poly(phenanthrenequinone) (PPQ) conductive polymer binder and poly(acrylic acid) (PAA) having good adhesion strength due to its carboxyl functional group. Blending between PPQ and PAA shows an effect that the adhesion strength of the Si electrode with the composite conductive binder is greatly improved after blending and this makes its better stable cycle performance. Blending ratios between PPQ and PAA in this work are 2:1, 1:1, 1:2 (by weight) and the best capacity retention at 50th cycle is observed in the electrode with the blending ratio 2:1 (named QA21). This is because that PPQ plays a role of conductive carbon among the Si particles or between Si particles and Cu current collector and PAA binds effectively the particles and the current collector. According to this synergetic effect, the internal resistance of the Si electrode with the blending ratio 2:1 is the smallest value. In addition, the Si electrode with PPQ-PAA composite binder shows the better stable cycle performance than the electrode with conventional super-P conductive carbon (20 wt.%).

  • Objectives : Knowledge about the management status of diabetic melitus (DM) is essential to improve diabetic management. Moreover, low income is associated with poor adherence to treatment and increased mortality. This study was performed to evaluate the management status of DM in low-income patients in a rural area. Methods : We enrolled 370 patients with type 2 DM living in Gokseong county, JeollaNamdo. A well-trained examiner measured the height, weight, waist circumference, blood pressure, total cholesterol, triglyceride, high density lipoprotein cholesterol, fasting blood sugar and glycosylated hemoglobin (HbA1c) levels. Carotid ultrasonography was used to measure carotid artery carotid artery intima media thickness (IMT) and plaque. anklebrachial index (ABI) was used to evaluate peripheral artery disease. A fundoscopic examination was performed to evaluate diabetic retinopathy. A history of diabetes complications and health-related questionnaires were also completed. Results : The age of diabetic subjects was 68.7$\pm$8.7 years and the duration of diabetes was 8.9$\pm$8.2 years. Most (63.5%) had hypertension, and 45.7% had triglycerides below 150 mg/dl, 38.1% had low density lipoprotein cholesterol (LDL) cholesterol below 100 mg/dl, 48.7% had urine albumin to creatinine ratio (UACR) below 30 mg/g. Less than half (45.9%) achieved the goal of HbA1c less than 7% suggested by the American Diabetes Association (ADA). 10.6% had peripheral vascular disease, 11.9% had retinopathy, and 60.8% had chronic kidney disease. Conclusions : DM management in low income patients is very poor and requires further work to improve.

  • This study analyzed the development and growth of folksonomy by examining tags associated with 40 bestsellers on LibraryThing.com in 6-month intervals. It was found that tag values do not decrease but grow in terms of quantity and quality. Accordingly, we examined the major significances of the tags and their potential utilization as an expression of subjects. Our findings were as follows. First, the motivations for tagging can be categorized into personal information for search purposes, self-fulfillment such as sense of achievement, display of emotion and sharing of one's experience with others, or an altruistic objective that emphasizes sociality with a desire that one's actions might provide social benefits. According to our analysis, 74.12% of tags had a social motivation. Second, the total number of tags and the frequency of usage increased with time. Third, the categories that showed a high increase in tag usage were dates of publication and reading, key words, main characters, and book reviews. Tags related to subjects had the highest ratio. Fourth, among Library of Congress Subject Headings (LCSH), multiple genres, key words and main characters were assigned to books, and specific key words and other properties were added as time progressed. There was also a slight increase in the number of tags consistent with LCSH. Fifth, we found that key tags could serve as a compilation of terms that reflects the knowledge base of the corresponding era. Thus, folksonomy should be continuously monitored for its quantitative and qualitative development of the tags to make improvements on its formative disadvantages, and identify internal semantic significance, be actively utilized in conjunction with taxonomy as a flexible compilation of terms that incorporate the history of a specific era.

  • The threat to information security is growing globally. To this, organizations are increasing the weight of adapting and operating the more specialized information security policy and system. Information security requires participation from the employees who execute the security system and policy, and to increase the level of organization's internal security, requires organization's systematic support to improve employees' information security compliance intention. This research finds the mechanism for improving employee's information security compliance intention by applying justice theory and goal setting theory in information security. We use structural equation modeling to verify the research hypothesis, and conducted a survey on the employees of organization with information security policy. In other words, this research performs verification of the research model based hypothesis which claims that security policy goal setting has positive influence on employee's level of security related justice recognition, and claims that justice has positive influence on compliance intention. The object of study is the employees of the organization that adapts information security policy, and 383 valid samples were collected via survey. Structural equation modeling was performed to verify the research hypothesis. The result shows that security policy goal factor (goal difficulty, goal specificity) improves employee's security related justice recognition, and that security related justice (distribution, process, and information justice) has positive influence on compliance intention. The result suggests the strategic approach directions for improving employees' compliance intention on organization's security policy.
