  • This research aims to understand how students of technical high schools view 'engineering' as well as to identify the main elements that contribute to the perception on 'engineering.' The research targets are 695 senior students of technical high schools nationwide. The researcher developed the measuring tool for the experiment by referencing the adjective value criteria utilized in the semantic difference method developed by Osgood (1957). There were a grand total of 30 criteria following the preliminary studies. The results of the research are as follows. Firstly, the average value of the overall perception of technical high school students on 'engineering' is 4.27 points. This value just exceeds the standard (4 points). Secondly, when examining the general tendency it can be noticed that there is a sense of stigma that although 'engineering' is significant and valuable it is a field that is overly difficult, complex and even dangerous. Thirdly, 6 main elements that influence the perception on 'engineering' were extracted as results of the factor analysis. The first element is practicality; the second element is emotions; the third element is aesthetics; the fourth is simplicity; the fifth is responsibility; and finally the sixth element is assertiveness. Fourthly, when comparing the average values of the perception on 'engineering' by region, it was seen that there existed a difference on the perception towards 'engineering' based on differing regions.

  • Objectives : The aim of this study was to develop and to verify the Korean version of the Eating Disorder Diagnosis Scale DSM-5 (K-EDDS) as a web-based diagnostic system, which enables rapid diagnosis of patients for early intervention. Methods : A total of 119 persons participated in the study, including patients with eating disorders (n=38) and college students (n=81). Along with the paper-and-pencil SCOFF, all participants completed the web-based K-EDDS, the Eating Disorder Examination-Questionaire (EDE-Q), and the Clinical Impairment Assessment Questionnaire (CIA). The semi-structured interview using the Eating Disorder Examination Interview (EDE) was conducted for participants with two or more SCOFF scores. Within two weeks, the web-based K-EDDS, the EDE-Q, and the CIA were re-tested. Results : In the exploratory factor analysis, four factors were extracted : body dissatisfaction, binge behaviors, binge frequency and compensatory behaviors. The four subscales of the web-based K-EDDS had significant correlation with each of the four subscales of the EDE-Q. The internal consistency of the web-based K-EDDS was highly satisfactory (Cronbach's alpha=0.93). The diagnostic agreement between the web-based K-EDDS and the EDE was excellent (96.83%), and the web-based K-EDDS's test-retest diagnostic agreement was fairly good (92.86%). The web-based K-EDDS and the CIA also showed significant differences between patients and general population, supporting discriminant validity. Conclusions : This study suggested that the web-based K-EDDS is a valid tool for assisting diagnosis of eating disorders based on DSM-5 in clinical and research fields.

  • The purpose of this study aimed to find the effect of self-esteem and communication competence on clinical practice stress of the Korean nursing students. A total of 198 nursing students participated in this study. Data collection was conducted through the use of questionnaires constructed to include the Rosenberg Self-esteem Scale, Global Interpersonal Communication Competence, and the Clinical Competence Scale. As a result, self-esteem, communication competence, and clinical practice stress of the Korean nursing students were found to be(Self-esteem: $3.4{\pm}0.57$; Communication competence: $3.5{\pm}0.42$; Clinical practice stress: $3.6{\pm}0.58$). Also, the nursing students with female(85.4%), experience of simulation on clinical training(72.2%) were found to have significantly higher clinical practice stress. Moreover, there were significant correlations between self-esteem and undesirable role model(r=.156, p=.029), communication competence and clinical practice stress(r=-.329, p<.001). The factors affecting clinical practice stress were communication competence, gender, satisfaction of clinical practice, and experience of simulation on clinical training. They amounted to 27.8% in clinical practice stress. The results indicate a need to develop effective teaching methods and learning strategies to decrease clinical practice stress of the nursing students.

  • This study was conducted to develop low-sodium Korean food recipes and evaluate consumer acceptability of low-sodium Korean food. A total of 137 consumers assessed the overall acceptability based on a 9-point scale. Statistical analyses were performed using the SPSS package program (ver 20.0). The results of this study are summarized as follows: According to the results of the consumer preference evaluation of low-sodium Korean food, overall acceptability of all menus was over five out of nine points (overall average 6.25). Overall acceptability was highest for grilled beef ribs (7.88), followed by bulgogi (7.63), sauteed dry anchovy (7.46), and simmered beef in soy sauce (7.45). On the other hand, overall acceptability was lowest in blanched and seasoned spinach (5.04). According to the results of Pearson's correlation analysis, overall acceptability was positively related with menu preference of 27 menus, including seasoned and simmered chicken (P<0.001), fiddledhead namul (P<0.001), and grazed lotus roots and burdock (P<0.001). To sum up, overall acceptability of all items used in the consumer preference evaluation was more than five points out of nine. Therefore, low-sodium recipe for Korean food can be effectively applied in commercial or non-commercial foodservice cafeterias.

  • This study explored the ESL college learners' perceptions on integrating reading and writing in the context of the reading-to-write composition classroom. Using the panel survey (N=60) that repeatedly measured the same set of individuals at three different times during a semester, this study examined whether students' perceptions on reading-writing integrations were reshaped over the course of classroom practices. The survey instrument was developed to assess the perception scores from less integrative continua to more integrative continua on a 5-point Likert scale. A two-factor ANOVA with repeated measures was performed to evaluate mean differences across the perception groups and over the three treatment times. The results do not demonstrate a significant treatment effect, suggesting that L2 learners' integrative perceptions were stable over the course of the semester. The dynamics in the perception changes differed widely across the perception groups. This result provides insights into understanding students' reading-writing practices and thus into instructional practices applicable to the classrooms. The present study argues for 12 learners' perceptions on integrating reading and writing as a key construct to understand their literacy practices involved in the composing process.

  • In multimedia database, a multidimensional space-based indexing has been used to increase search efficiency. However, this method is inefficient in terms of ubiquity because it uses Euclidean distance as a scale of distance calculation. On the contrary, a metric space-based indexing method, in which metric axiom is prerequisite is widely available because a metric scale other than Euclidean distance could be used. This paper is attempted to propose a way of improving VP-tree, one of the metric space indexing methods. The VP-tree calculates the distance with an object which is ultimately linked to the a leaf node depending on the node fit for the search range from a root node and examines if it is appropriate with the search range. Because search speed decreases as the number of distance calculations at the leaf node increases, however, this paper has proposed a method which uses the latest interface on query object as the base point of trigonometric inequality for improvement after focusing on the trigonometric inequality-based range compression method in a leaf node. This improvement method would be able to narrow the search range and reduce the number of distance calculations. According to a system performance test using 10,000 video data, the new method reduced search time for similar videos by 5-12%, compared to a conventional method.

  • This study was performed to examine the quality characteristics of the sponge cakes with different contents (2-10% (w/w)) of lemon grass powder (LGP). An increase in LGP content in the cake led to a significant increase in the specific gravity of batter, baking loss rate, redness, hardness, cohesiveness, chewiness, and 1,1-diphenyl-2-picrylhydrazyl radical scavenging activity of the cakes and a significant decrease in pH, moisture content, specific volume, height, volume and symmetry index, lightness, and yellowness of the cakes. Springness and resilience did not show any difference between the cakes. The consumer acceptance test indicated that the addition of LGP up to 2% did not cause a significant negative effect on the consumer acceptances in all attributes. The sponge cakes with 2% LGP can be recommended for manufacturing bakery.

  • The effectiveness of various additives in reduction of an unpleasant odor and inhibition of Bacillus cereus growth in Cheonggukjang (CKJ) was investigated. Sensory evaluations of unpleasant odor intensity and taste preference for CKJ were conducted with a 5-point scale. Raw CKJ was rated to have the highest unpleasant odor intensity, followed by CKJ-salt, CKJ-wood vinegar salt, CKJ-red pepper seed oil, and CKJ-bamboo salt in the given order. The test panel had a greater preference for CKJ-red pepper seed oil than for the other CKJ products. The addition of bamboo salt to CKJ was the most effective in inhibition of B. cereus growth in comparison to the other three additives. Volatile compounds in CKJ and CKJ-bamboo salt were identified by GC/MS analysis. 1-Ethoxy-1-methoxy-ethane was responsible for the pleasant odor and its level significantly increased in CKJ-bamboo salt. Consequently, adding bamboo salt to CKJ not only masked and reduced the unpleasant odor, but also inhibited B. cereus growth in CKJ.
