For web application vulnerability diagnosis, from the development stage to the operation stage, it is possible to stably operate the web only when there is a policy that is commonly applied to each task through diagnosis of vulnerabilities, removal of vulnerabilities, and rapid recovery from web page damage. KISA presents 28 evaluation items for technical vulnerability analysis of major information and communication infrastructure. In this paper, we diagnose the vulnerabilities in the automobile goods shopping mall website and suggest security measures according to the vulnerabilities. As a result of diagnosing 28 items, major vulnerabilities were found in three items: cross-site scripting, cross-site request tampering, and insufficient session expiration. Cookie values were exposed on the bulletin board, and personal information was exposed in the parameter values related to passwords when personal information was edited. Also, since the session end time is not set, it was confirmed that session reuse is always possible. By suggesting security measures according to these vulnerabilities, the discovered security threats were eliminated, and it was possible to prevent breaches in web applications and secure the stability of web services.

Due to the global epidemic of infectious diseases, it has become important for all industries to respond to the risk of infectious diseases. Ports in each country are also responding to the risk of infectious diseases, but the occurrence of infectious diseases in ports of various countries is causing a lot of damage to the logistics of ports. Korea is in the same situation, and cases of infectious diseases in ports are steadily being announced. Therefore, this paper conducted semi-quantitative Bow-Tie risk assessment by substituting measures to cope with infectious disease risks in Korean ports into actual cases of port infectious diseases in Korea, deriving improvements and suggesting directions. As a result, it was concluded that it was necessary to standardize some of the countermeasures against infectious diseases and develop more countermeasures.

This study aimed at examining the career decision level of Clothing and Textile major college students in Seoul area. With the increasing rates of youth unemployment, preparing college students for their future career and guiding them in making career decision is imperative. Students' satisfaction with their major and motivation orientation were considered as influencing factors, as well as their demographic characteristics. A survey was conducted to 282 students majoring Clothing and Textiles at seven universities and 277 completed questionnaires were used for analysis. The questionnaire measured respondents' major satisfaction, motivational orientation, career decision level, and demographics (gender, age, school and department names, class standing, expected graduation date, subjective social status, and GPA). Descriptive statistics, K-means cluster analysis, one-way analysis of variance followed by Duncan multiple comparisons were conducted. The results indicated that Clothing and Textiles majors were overall satisfied with their major, but the satisfaction level was higher for female than male students. Those who were satisfied with their major were less likely to feel anxious about career decision-making. The High-Motivation group and the Intrinsic-Motivation group showed lower anxiety over career decision-making compared to Low-Motivation and Extrinsic-Motivation groups. This study has implications for college advisors in that it provides basic information on students' career decision level and the influencing factors.

Methods: The subjects were 202 high school girl students visiting K university in October, 2014 and in January, 2015 for the interview of early and regular admission to the university. The questionnaire consisted of 3 questions of general characteristics of the subjects, 40 questions of gender role identity, and 6 questions of career choice factors. Gender role identity included 15 questions of masculinity, 15 questions of feminity, and 10 questions of neutral gender using instrument of Kim by Likert scale. Cronbach's alpha of masculinity, feminity, and neutral gender was 0.810, 0.762, and 0.801 respectively. The data were analyzed using ${\chi}^2$-test with SPSS Win 12.0. Results: The effects of gender role identity on major choice and professionalism were as follows. In major choice motivation, psychological type, feminity type and masculinity types selected aptitude, professional sustainability and recommendation by acquaintance in order, but undifferentiated type selected aptitude, recommendation by acquaintance and professional sustainability in order. There was a statistically significant difference(p<0.05). In major choice information, psychological, feminity and undifferentiated types prefer indirect experience but masculinity type prefers direct experience. There was a statistically significant difference(p<0.05) In job selection, psychological, feminity and undifferentiated types want to do assistant works rather than oral health prevention and education. Masculinity type want to do oral health prevention and education rather than assistant work. There was a statistically significant difference(p<0.001). Conclusions: The gender role identity affected the factors related to choice of major and job in dental hygiene major applicants.

Purpose: This study attempted to provide the basic data for the institutional improvement of the clinical practice of physical therapy department students. Methods: Research for this study included 390 participants used for the analysis of the present study. The statistical analysis was of the characteristics and satisfaction of the clinical practices of subjects, the reasons for major employment preferences before and after clinical practices, and the preferred institution and field of major employment before and after clinical practice. Results: The general characteristics of students of the physical therapy department include females in their third year of college at age 20~24 years-old. As well, no religion, usual satisfaction with major, and motivation of choosing a physical therapy employment rate were the most common. A residency type in the form where one would cook one's own food and a clinical practice with a general hospital grade were seen most often. Regarding preference of major employment before and after clinical practice, the preference of major employment was 88%, which increased by 5.2% after clinical practice from 82.8% before clinical practice. The preference for no major employment due to lack of interest and no aptitude increased 43.5% from 23.9% after clinical practice. Conclusion: The number of apprentices will increase despite practice institutions being limited; for practice of environment, content, etc., relatively changes are slow, and progress rapidly medical technology. It is a society in which expertise is required; in the present study, there is a value in providing the clinical data missing in physical therapy.

This paper presents the method to quantitatively evaluate the uncertainty of the semi-empirical Bidirectional Reflectance Distribution Function (BRDF) model for Himawari-8/AHI. The uncertainty of BRDF modeling was affected by various issues such as assumption of model and number of observations, thus, it is difficult that evaluating the performance of BRDF modeling using simple uncertainty equations. Therefore, in this paper, Monte-Carlo method, which is most dependable method to analyze dynamic complex systems through iterative simulation, was used. The 1,000 input datasets for analyzing the uncertainty of BRDF modeling were generated using the Second Simulation of a Satellite Signal in the Solar Spectrum (6S) Radiative Transfer Model (RTM) simulation with MODerate Resolution Imaging Spectroradiometer (MODIS) BRDF product. Then, we randomly selected data according to the number of observations from 4 to 35 in the input dataset and performed BRDF modeling using them. Finally, the uncertainty was calculated by comparing reproduced surface reflectance through the BRDF model and simulated surface reflectance using 6S RTM and expressed as bias and root-mean-square-error (RMSE). The bias was negative for all observations and channels, but was very small within 0.01. RMSE showed a tendency to decrease as the number of observations increased, and showed a stable value within 0.05 in all channels. In addition, our results show that when the viewing zenith angle is 40° or more, the RMSE tends to increase slightly. This information can be utilized in the uncertainty analysis of subsequently retrieved geophysical variables.

Objectives : Reactive oxygen species (ROS) have been associated with pathogenic processes including carcinogenesis through direct effect on DNA directly and by acting as a tumor promoter. Therefore, it has been regarded that ROS may be a major target for cancer prevention. The root of Paeonia lactiflora pall (PL), a traditional Chinese herb, has been a component of effective prescriptions for treatment of liver disease. Also, there are some reports about the antioxidant activities of the extracts from PL. However, little has been known about the effects of PL against oxidative damage. This work aimed to elucidate the anti-oxidant effects of Paeonia lactiflora pall (PL) in the non-cellular system and cellular system. Methods : Antioxidant activities of PL were evaluated by hydroxyl radical scavenging assay and $Fe^{2+}$ chelating assay. Anti-oxidative effect of PL was evaluated by ${\varphi}X$-174 RF I plasmid DNA cleavage assay in non-cellular system. In addition, DNA migration assay, expression level of phospho-H2AX, MTT assay and lipid peroxidation assay were performed for evaluate the anti-oxidative effect of PL in cellular system. Results : PL had a dose-dependent hydroxyl radical scavenging and $Fe^{2+}$ chelating capacity. In addition, PL inhibited oxidative DNA and cell damage induced by hydroxyl radical in non-cellular system and cellular system. Conclusion : Taken together, P. lactiflora pall may be possible for the application to a potential drug for treating the oxidative diseases such as cancer.
