The purpose of this study was to identify the effects of clinical nurses' intrinsic motivation, affective commitment, and turnover intention on organizational performance. Participants were 189 nurses currently working at four general hospitals in C city. Data were collected by a self-report questionnaire and analyzed by using the SPSS/WIN 18.0 program with descriptive analysis, t-test, ANOVA, Pearson correlation coefficient, and multiple regression. Mean scores were as follows: intrinsic motivation($3.02{\pm}0.57$), affective commitment ($3.47{\pm}0.71$), turnover intention ($3.30{\pm}0.59$), and organizational performance ($3.37{\pm}0.52$). Organizational performance was significantly correlated with intrinsic motivation, affective commitment, and turnover intention. Nurses with higher affective commitment and intrinsic motivation showed higher organizational performance, where as higher turnover intention was correlated with lower organizational performance. The factors that influenced organizational performance were affective commitment(${\beta}=.42$), intrinsic motivation(${\beta}=.36$), and turnover intention(${\beta}=-.11$), with an explanatory power of 51.6%. Results of this study indicate the need to evaluate and manage the significant predictors of organizational performance. Further studies are needed to identify the relationships between clinical nurses' intrinsic motivation, affective commitment, turnover intention, and organizational performance.

In context awareness using multiple sensors, when using sensor data detected and sent by each sensor, it is necessary to give different weights for each sensor. Even if the same type of sensor is configured for the same situation, sometimes it is necessary to assign different weights due to other secondary factors. It is inevitable to assign weights to events in the real world, and it can be said that a weighting method that can be used in a context awareness system using multiple sensors is necessary. In this study, we propose a weighting method for each sensor that reports to the host while the sensors continue to detect over time. In most IoT environments, the sensor continues the detection activity, and when the detected value shows a change pattern beyond a predetermined range, it is basically reported to the host. This can be called a kind of data stream environment. A weighting method was proposed for sensing data from multiple sensors in a data stream environment, and the new weighting method was to select and assign weights to data that indicates a context change in the stream.

The purpose of this study was to investigate the effects of role assignment in a group on collaboration in a mid- dle school science class to which Collaborative Problem Solving for Character Competency (CoProC) model was applied. For this purpose, 4 classes in the second year of a middle school located in a small and medium-sized city were selected, two classes among these were assigned roles, and the other classes were not. The science class with 4 topics using CoProC model was carried out. As a result of the study, in middle school science class to which CoProC was applied, it was effective in increasing the collaboration. As a result of analyzing the discussion process using the analysis framework for collaboration developed in this study, the group without role assignment was statistically significantly higher than the group with role assignment in the total score and the four sub-factors, especially in 'partnership building' and 'consensus building' which is a high level of collaboration.

This paper examines the discussions related to image and signification through the theories of Roland Barthes. We have already been able to see through the studies of Semiotics and Anne H?nault that the denotation is distinguished from the connotation in the linguistic dimension. Through the analysis of the advertising image of Barthes, we have seen that the syntagmatic relationship can make the sense of the image objective. From this study, we also emphasized that it is possible to subjectively interpret images that deviate from the syntagmatic relationship. In addition, we examined the concepts of Studium and Punctum by Barthes. With this we have found that the definition of a personal meaning to objects has a theoretically clear position. Finally, we have been able to understand the concept of 'le sens obtus' through the article ${\ll}$ Le troisi?me sens ${\gg}$. The notion of 'sens obtus' makes it possible to realize that the objective and clear sense of object is not the one chosen primarily from the subject. By facing an object such as an image to be interpreted, the subject is placed in a situation where he is not compelled to choose a meaning but rather he chooses one of the possible senses. This makes it clear that the semantic levels provided by semiotic theories are limited to the analytic dimension.

This study examines various weighting methods for improving the performance of automatic classification based on Rocchio algorithm on two collections(LISA, Reuters-21578). First, three factors for weighting are identified as document factor, document factor, category factor for each weighting schemes, the performance of each was investigated. Second, the performance of combined weighting methods between the single schemes were examined. As a result, for the single schemes based on each factor, category-factor-based schemes showed the best performance, document set-factor-based schemes the second, and document-factor-based schemes the worst. For the combined weighting schemes, the schemes(idf*cat) which combine document set factor with category factor show better performance than the combined schemes(tf*cat or ltf*cat) which combine document factor with category factor as well as the common schemes (tfidf or ltfidf) that combining document factor with document set factor. However, according to the results of comparing the single weighting schemes with combined weighting schemes in the view of the collections, while category-factor-based schemes(cat only) perform best on LISA, the combined schemes(idf*cat) which combine document set factor with category factor showed best performance on the Reuters-21578. Therefore for the practical application of the weighting methods, it needs careful consideration of the categories in a collection for automatic classification.

The main purpose of this study was to empirically investigate the effects of participation behavior and performance improvement on motivation factors of Korean university students which participated in LINC by utilizing Vroom's Expectancy Theory. Three motivation factors of valence, instrumentality, and expectancy were examined in this study. In addition, two different models (valence and force model) analyzed the causal relationships regarding participation behavior and performance improvement. 236 data were collected and findings of this study were as follows: First, comparative analysis between demographic characteristics including university, major, and residence had no significant differences in mean value. However, females had higher levels of recognition related to valence (attractiveness) relative to males. Second, valence and the force model were significant predictors of LINC participation behavior and performance improvement. Furthermore, the coefficient of determination and beta coefficient of the force model were higher compared with the valence model. Third, the level of mediation effects including direct, indirect, and total effect of the force model was higher than the valence model. LINC participation behavior had a partial mediating effect between the three motivation factors and performance improvement variable.

광 계측 기술은 지금까지 단독으로 진보되어 온 것이 아니라, 다른 계측 수단과 병용함으로써 부가적인 정보를 부여하는 기술로서, 또 어느 대상 물체에 대하여 어떤 계측 조건하에서는 다른 계측 방법에 비하여 유효하게 사용할 수 있다는 관점에서 발전되어 왔다. 본 고에서도 각 응용 분야가 안고 있는 앞으로의 목표를 광 계측 기술을 어떻게 활용하면 달성할 수 있을지라는 관점에서 설명하였다.
