Purpose: This exploratory study aims to identify the influence of clinical practice belonging, satisfaction with major, and work values on the level of career identity among nursing students. Methods: The subjects of this study are 251 senior students from three nursing departments located in a metropolitan city. Using SPSS 22.0, the study uses technical statistics, t-test, One-way ANOVA, correlation, and multiple regression analysis. Results: The average scores for clinical practice belonging, satisfaction with major, and work values were 3.61, 3.87, and 3.70 out of 5.00, respectively, and 2.85 out of 4.00 for career identity. The factors affecting students' career identity were clinical practice belonging, aptitude, satisfaction with clinical practice, satisfaction with major, indoor work, service and employment at hospitals with 40 percent being explained by these variables. Conclusion: Through this study we found that clinical practice belonging has the greatest impact on career identity. In order to enhance clinical practice belonging, universities and clinical institutions need to develop new programs and curricula.

Purpose: This study undertakes to identify factors influencing the perception university students in Korea hold toward having children. Method: A cross-sectional, descriptive study was conducted on 187 university students (79 males and 108 females) from one university located in a metropolitan area. Participating students completed a packet of self-report questionnaires on values concerning gender roles, marriage, family and children along with their personal demographic details. The resulting data were analyzed using t-tests, one-way ANOVA and Pearson's correlation coefficients as well as descriptive statistics. Stepwise multiple regression was performed to identify factors that most influenced the value of children held among university students. Results: The value of having children was negatively associated with the value of family, but positively associated with the value of marriage. In addition, the value of family had a negative relationship with the value of marriage, but a positive relationship with the value of gender role. Stepwise multiple regression found that the equation consisting of gender and value of marriage explained about 42.0% of the variance of the value of having children. Conclusion: Considering the findings from this study, programs promoting the positive values of marriage are required for university students to have positive values toward having children.

As the compact and easily accessible handheld devices, such as cellular phones and MP3 players equipped with image acquisition functionality, are becoming widely available among common users, various applications of images are rapidly increasing. Image related services and software such as web-based image presentation and image manipulation for personal or commercial purpose enable users to view contents of remote image archive and to manipulate enormous amount of images in local or network based storage as well. It is necessary for users to identify the images efficiently so that the same images are perceived as one physical entity instead of recognizing them as different images as the trends are getting stronger. In order to support this environment, we propose a method that generates image identifiers or indexing for images within a solid and efficient manner. The proposed image identifier utilizes multiple index values. The integration of component index values creates a unique composite value that can be used as a file name, file system identifier, or database index. Our experimental results on generation of constituent index values have shown favorable results.

Purpose: This study aims to review existing research on the definition, conceptualization, and measurement of relationship values to guide future research. This study specifically measures the relationship value between principals and retailers, which is still not widely discussed in previous research. Besides, to broaden our knowledge of the value-based determinants of competitive advantage, satisfaction, and retailer loyalty in business-to-business relationships. Research design, data, and methodology: This research assessed three alternative models of the relationship value construct's dimension structure and then tested for reliability, validity, and confirmatory factor analysis. The research sample is 185 retailers-data analysis using Structural Equation Modeling (SEM). Results: The results showed that product-based values and relationship-based values positively influenced competitive customer advantage, satisfaction, and loyalty. Conclusions: Relationship value construct can be measured and consist of five dimensions: product quality, delivery performance, customer orientation, service support, and personal interaction. They are key factors that maintain the relationship between principal and retailers. This study indicates that principals must invest more time and effort in building valuable relationships with their retailers. Finally, the value of relationships is a determinant of retailer performance: satisfaction and loyalty.

The purpose of this study is reveal the relationship between halitosis and personal profile. The personal characteristics of halitosis patient were studied by symptom checklist-90- revision(SCL-90-R). 135 halitosis patients, 118 TMD patients(control torup 1) and 90 normal persons(control group 2) were selected for this study at the halitosis clinic or the Department of Oral Diagnosis and Oral Medicine, Kyung Hee Dental Hospital. T-scores were analyzed with Korean manual of SCL-90-R. A t-test was used to evaluate the overall group effect and the values were significant at the 0.05 level. The obstained results were as follows : 1. Mean value of T-scores on 9 basic scales of SCL-90-R in all groups(Halitosis patients, TMD patients and normal) was within normal range. 2. When compared with normal group, TamD patients gorup were significantly higher in sclaes of Somatization (p<0.01), Obsession-Compulsion(p<0.05), Depresison(p<0.05), Anxiety(p<0.01), Hostility(p<0.05). 3. When compared with normal group, halitosis patients group were significantly higher in scales of Somatization(p<0.05), Obsessoin-Compulsion(p<0.05), Interpersonal Sensitivity (p<0.05), Psyhcoticism(p<0.05). This data suggests that psychopathologic trends may be associated with halitosis and can be estimated by SCL-90-R questionnaire.

This paper proposes a smart phone authentication method based on user's behavior and habit that is an authentication method against shoulder surfing attack and brute force attack. As smart phones evolve not only storage of personal data but also a key means of financial services, the importance of personal information security in smart phones is growing. When user authentication of smart phone, pattern authentication method is simple to use and memorize, but it is prone to leak and vulnerable to attack. Using the features of the smart phone pattern method of the user, the pressure applied when touching the touch pad with the finger, the size of the area touching the finger, and the time of completing the pattern are used as feature vectors and applied to user authentication security. First, a smart phone user models and stores three parameter values as prototypes for each section of the pattern. Then, when a new authentication request is made, the feature vector of the input pattern is obtained and compared with the stored model to decide whether to approve the access to the smart phone. The experimental results confirm that the proposed technique shows a robust authentication security using subjective data of smart phone user based on habits and behaviors.

Most internet users utilize internet portal search engines, such as Naver, Daum and Google nowadays. But since the results of internet portal search engines are based on universal criteria (e.g. search frequency by region or country), they do not consider personal interests. Namely, current search engines do not provide exact search results for homonym or polysemy because they try to serve universal users. In order to solve this problem, this research determines keyword importance and weight value for each individual search characteristics by collecting and analyzing customized keyword at external database. The customized keyword weight values are integrated with search engine results (e.g. PageRank), and the search ranks are rearranged. Using 50 web pages of Goolge search results for experiment and 6 web pages for customized keyword collection, the new customized search results are proved to be 90% match. Our personalization approach is not the way that users enter preference directly, but the way that system automatically collects and analyzes personal information and then reflects them for customized search results.

Study on children from international marriage so far has been conducted focusing on the school-aged children, and it uniformly presents those children as a mere being with problem, overlooking regional variables of rural area. Hence, this study aims to seek various means of adaptation of children from international marriage by considering both variables rural area and adolescence. For this study, six children from international marriage living in the rural area of H county in Jeonlanamdo were chosen, in-dept interview were conducted, and Giorgi(1985) was used to analyze qualitative data. The results shows that these adolescences appear to have extensive experiences in the areas of learning, personal relationship, home and identity. Level of academic achievement was influenced by what school they attend to, and personal relationship aspect was affected by prejudice and discriminative perception from people around them. In addition, in home environment, hatred toward father, sympathy for mother, comparison with mothers who have great cultural adaptation skills, and pressure as the firstborn appear to be on the increase. Adolescent children tend to be addicted to internet games in order to escape from anxiety, experiencing identity crisis. They tend to be negative about international marriage of their parents, and exhibit behaviors refusing values and religious view of their parents. At the conclusion, limitation of the study and suggestion for further study are presented.
