Purpose - The purpose of this study is to clarify the difference of store attributes of Korean consumers and to analyze it's influence on consumer satisfaction in duty free stores which gain ground inch by inch in the distribution chanel. And it is to find discriminative result as compared with foreign consumer. Research design, data, and methodology - Subjects for the quantitative study, quota sampling was adopted in the Lotte, Shilla downtown and airport duty free stores from the first to 15^th December 2016 and 177 questionnaires from Koreans who had purchasing experience in off line duty free store were analyzed. The data was analyzed by using factor and reliability analysis, descriptive statistics analysis, the independent sample t-test and multiple regression analysis. To test consistency, Cronbach's alpha was used. Results - The result were as follows; 1. Korean consumers consider the importance of store attributes in duty free stores in order Product, Economic Feasibility, Convenience, Promotion, and Accessibility. 2. The meaningful impactive factors of duty free store attributes on consumer satisfaction turned out Product and Promotion. 3. These results show meaningful distinction between Koreans and foreigners in terms of consumer satisfaction in duty free stores. Conclusions - A marketer who is working for duty free store consider now that price benefit can not give strong impact to Korean consumers more and should concentrate on various brand assortment even including private brand. In terms of promotion, most duty free shops put special stress on foreign consumer's wants now as highly increasing of Chinese travelers but Korean consumer's sales portion and number of visitor also are steadily increasing. Therefore, a duty free marketer should prepare the Korean-oriented services with more enhanced promotion strategies for individual and group travellers, for example, a mileage service, VIP room and social network system to satisfy Korean consumers. In order to get satisfaction from Korean consumers, it makes effort on product and promotion than accessibility, price and convenience. Due to high level influence, further study is needed to enlarge to on-line market and to develop private brands for duty free stores.

In this paper, we propose the secure key management framework to connect USN with different network. Although connected USN with different network has no CA (Certificate Authority), it is important to use public key based cryptography system because this network consists of numerous devices. The proposed mechanisms focus on device authentication and public/private key management without existing PKI system of IP network. To solve no CA and certificate problems, the IDC (Identity Based Cryptography) concept is adopted in our proposed mechanism. To verify the possibility of realization, we make an effort to implement the proposed mechanisms to real system. In the test bed, both USN and PLC network are connected to IP network; and proposed mechanisms are implemented to PLC and sensor devices. Through this test using the proposed mechanism, we met the similar performance with symmetric algorithms on key generation and update process. Also, we confirmed possibility of connection between different network and device authentication.

Objectives: The main purpose of this study was to examine factors contributing the quality of life related to oral heath such as level of oral health knowledge, subjective knowledge on oral health, awareness of oral health and OHIP-14, and furthermore to analyze any relations among these factors. Methods: The questionnaire survey was carried out on a convenience sample of 230 middle school students at the selected middle school in Chungcheongnam-do. T-test and one-way ANOVA and correlation test were conducted over the collected datas using SPSS 12.0(SPSS 12.0 KOR for Windows, SPSS Inc, Chicago, USA). Results: The results of the study are as follows: 1. 6.38 was average score for oral health knowledge and 10.0 was the maximum. Subjective oral health awareness scored of average 2.99 with maximum of 5.0. OHIP-14 corresponded to average 4.30 and maximum 5.0. 2. Different level of oral heath knowledge was resulted from that of education, which means the greater level of oral health knowledge indicated greater awareness of oral health. 3. OHIP-14 was higher for those who lived with their parents than those who in did not(P=0.012). 4. There exhibits a proportional relationship between subjective awareness of oral health and OHIP-14(r=0.297). Conclusion: It was found that subjective awareness of oral health partially influences to OHIP-14. In other words, subjective awareness of oral health has an effect on the quality of life related to oral health. Hence, there needs more effort on oral health education and oral disorder prevention activities in order to improve subjective awareness of oral health.

In order to provide data of effective health education for practice of preventive health behavior for visual acuity care. The authors investgated the actual acuity and health behavior for visual acuity care. The subjects of this study were 2250 students in high school. The data were collected by questionnaire developed for the purpose of this study which has been made through references and student's health record. The results were as follows, 1) As students move up to grade, the number of students with decreased visual acuity had a tendency to increase. In cases with decreased visual acuity below 0.2 in one or both eye, the number of cases was increased in accordance with moving up to grade, especially visual acuity of right eye was more decreased than that of left eye. 2) As to proportion of the group with decreased visual acuity among the total students, among 2250 students, students with decreased visual acuity was 35.6%(800 students). According to school type, in academic school, frequency of students with decreased visual acuity in day school was higher then that in night school. In commercial school, the frequency of students who had decreased visual acuity in night school were higher than that of students in day school. 3) As to variables influencing the decreased visual activity, there was a significant different between groups with normal visual acuity and groups with subnormal in terms of awareness of visual acuity by themself, parent's visual acuity, unbalanced eating habit, distance from television, or books, posture in watching television, posture in reading, awareness of illumination in classroom. 4) As to practice of protective and preventive health behavior for visual acuity care, In group with normal visual acuity. There was good practice such as proper eating habit, proper studying habit, and health habit in its descending order, but proper illumination and regular eye test were practiced poorly. In group with subnormal visual acuity, one of the vest practice in visual acuity care was an effort to prevent eye strain. Other good practice involve tasking regular eye test, maintaining proper studing habit, in its descending order.

Objectives: This study aimed to investigate factors related to prostate disease and follow-up procedure on health examination program in Gangwon-do. Methods: The studied population was 16,501 male aged 40 or more, who underwent screening tests for prostatic disease in 2011 health examination program designed for the low income residents in Gangwon-do. The screening tests included prostate specific antigen (PSA), international symptom score (IPSS), and maximal flow rate (Qmax). We conducted chi-square test for trend, two independent samples t-test, and binary logistic regression to find out the relationship between prostate cancer or benign prostatic hyperplasia and risk factors such as age, PSA level, and IPSS. Results: The number of subjects who turned out positive for PSA level (> 3.8ng/ml) was 971 men accounting for 5.9%. The result of post survey on them showed that 511 subjects (52.6%) got the urology check-up: 156 (30.5%) were diagnosed as normal, 286 (56.0%) as benign prostatic hyperplasia, and 69 (13.5%) as prostate cancer. The detection rate for prostate cancer was 8.8% when PSA level was between 3.81 and 9.99g/ml, and was 30.6% when PSA level was more than 10.00ng/ml. The rates of further testing varied depending on the communities from 26.7% to 68.2%, which was mainly affected by the role of local health center. Conclusions: Our findings indicate that enhanced quality control of local health center and empowerment of screening agency would increase the effort of coupled institutions between public and private sectors.

The purposes of this study were to investigate the social instrumentality of appearance, appearance orientation, and cosmetics purchasing behaviors of Chinese male consumers, and to find differences in the cosmetics purchasing behaviors of the male consumer groups, which were segmented by the social instrumentality of appearance and appearance orientation. The subjects were 400 adult males in their 20s to 30s from Gillim province in China. The measurements consisted of the social instrumentality of appearance, appearance orientation, cosmetics purchasing behavior, and the subject' demographic attributes. The data was analyzed by descriptive statistics, frequency analysis, $x^2$ test, multiple response analysis, cluster analysis, ANOVA, and Duncan's multiple range test, using SPSS program. The results were as follows. First, young Chinese male consumers had a high sense of the social instrumentality of appearance, but the tendency to invest time and effort to enhance their looks was still low. Second, on the basis of the social instrumentality of appearance and appearance orientation, young Chinese male consumers were classified into four groups (high involvement group, instrumentality group, orientation group, and low involvement group). Third, the four male consumer groups revealed many significant differences in various cosmetic purchasing behaviors (purchasing items, information sources, product selection criteria, purchasing motives, purchasing locations, store selection criteria, purchasing price, purchasing frequency, and cosmetics improvements). Therefore, the social instrumentality of appearance and appearance orientation are seen as significant variables to effectively segment the Chinese male consumer market. The cosmetics companies targeting young Chinese men need to establish differentiated marketing strategies, considering the characteristics of each segment of the consumer market.

Structural properties of reinforced concrete, such as bond and shear strength, that depend on the tensile properties of concrete are much lower for high-strength concrete than would be expected based on relationships developed for normal-strength concretes. To determine the reason for this behavior, studies at the University of Kansas have addressed the effects of aggregate type, water-cementitious material ratio, and age on the mechanical and fracture properties of normal and high-strength concretes. The relationships between compressive strength, flexural strength, and fracture properties were studied. At the time of test, concrete ranged in age from 5 to 180 days. Water-cementitious material ratios ranged from 0.24 to 0.50, producing compressive strengths between 20 MPa(2, 920 psi) and 99 MPa(14, 320psi). Mixes contained either basalt or crushed limestone aggregate, with maximum sizes of 12mm(1/2in). or 19mm(3/4in). The tests demonstrate that the higher quality basalt coarse aggregate provides higher strengths in compression than limestone only for the high-strength concrete, but measurably higher strengths in flexure, and significantly higher fracture energies than the limestone coarse aggregate at all water-cementitious material ratios and ages. Compressive strength, water-cementitious material ratio, and age have no apparent relationship with fracture energy, which is principally governed by coarse aggregate properties. The peak bending stress in the fracture test is linearly related to flexural strength. Overall, as concrete strength increases, the amount of energy stored in the material at the peak tensile load increases, but the ability of the material to dissipate energy remains nearly constant. This suggests that, as higher strength cementitious materials are placed in service, the probability of nonductile failures will measurably increase. Both research and educational effort will be needed to develop strategies to limit the probability of brittle failures and inform the design community of the nature of the problems associated with high-strength concrete.

Purpose: The purpose of this study was to provide basic data which is necessary for educating nursing and medical students for establishing a desirable sense of ethics values Method: In this descriptive research, a total of 140 nursing students and 124 medical students were selected. The tools used for data analysis were descriptive statistics, t-test, one-way ANOVA, and Scheffe test by using SPSS/WIN 12.0 version. Result: When the differences in the consciousness of biomedical ethics of nursing and medical students were compared, statistically significant differences were found in the category of brain death (t=-3.26, p=.001). Statistically significant differences were found in the general characteristics of religion (F=3.05, p=.018), and participation in religious activity (F=3.34, p=.006). Statistically significant differences were found in the characteristics related to the subjects' ethical values such as satisfaction level of a nurse/doctor (F=7.39, p=.000) occupation, the experience of A Patient's Bill of Rights (F=2.97, p=.020), the intention to attend biomedical ethics (F=5.61, p=.000), and the possibility of increasing ethical problems according to the development in the field of medical science (F=7.92, p=.000). Conclusion: An effort should be made to overcome the differences in the perception of biomedical ethics between nursing students and medical students. Moreover, when investigating the course of an integrated education for the establishment of a desirable sense of biomedical ethics, an alternative plan that could promote ethical values must be considered so that the significant variables can promote bioethical perception.

Brake system is indispensible functional part to the transportation machines such as railroad cars, and all of industrial machines. It is mechanical element to stop the movement or slow the speed, transforming kinetic energy of motion object into thermal energy through solid friction. According that recently the railroad cars have become high-speed, the technique in braking domain to secure the overall braking effort is making rapid progress. In particular, material development and manufacturing process are so important to secure friction performance, which is the core in braking performance of mechanical brake units. Wear of brake disk could mainly result in the diminishment of its life span due to thermal cracking, so the endurance against high temperature is required. On the other hand, in this case, the problem is that the side wear of pad, relative material is slightly increased because of enlargement of plastic deformation. It is necessary, therefore, to develop a disk material that will be used in the Tilting System mechanical brake units. The purpose of this paper is to make a study prior to developing brake disk of Tilting Train travelling at 200km/h and to propose the component of brake disk. Accordingly, I will conduct sufficient researches on technical documents of brake disk, that are basic documentations, analyze an impact on components, and further, considering braking degree of train, study for the basic proposal on brake disk's component of the train travelling at 200km/h, which has relatively minor influence of heat stress and maintains the friction. In this respect, I would like to investigate friction characteristics between disk and relative friction material via Test on some possible test segments, analyze and propose friction performance, temperature impact and so forth coming from the contact with pad, relative material to demonstrate the friction characteristics.
