While online surveys are considered to be the viable alternative to face-to-face and telephone surveys, many clients express a strong concern about the possibility of unreliable responses. Given this concern, survey experts hypothesize that amounts of time on responding can represent the extent to which respondents fill out the questions with sincerity. This study examines this hypothesis using data from an online survey sample of 1.052. Results strongly suggest that while "long time" informants are reliable, "short time" informants are not. Those in the short time group spend only 2.4 seconds per question and show very different patterns of responses to 49 Likert -typed questions. Logistic regression results imply that these unreliable respondents are interested in monetary gifts and maybe as a result, participate in surveys much more frequently. In conclusion, we provide some implications of these results to the quality of online surveys.

The purpose of this study was to develop 'the problem situations' for the Problem Based Learning(PBL) and to examine it's effects on the science achievement and the attitude towards science learning. Also the students' perception on the PBL model was examined. The topics of the problem situations developed were 'the future energy for reducing the green house effect' and 'the Indonesian forest fire and the El Nino'. The coaching strategies for the PBL were designed and implemented to 10th grade high school students in the science classes, the results are follows; First, the science achievement of the group of PBL is significantly higher than those of group of traditional teaching. Second, the scores of the test of attitude toward science learning of the group of PBL is significantly higher than those of group of traditional teaching. Third, the students' perception of the PBL was positive. Many students have interests and motivations in PBL, some students have difficulties in learning on the PBL. In the students' personal reflection notes the step of a problem statement is the hardest one of the PBL model. Therefore, this study suggests that developing the problem situations based on real context is of great importance for implementing a problem based learning model continuously.

Science teachers' perception on their preparation program can help in conceptualizing how science teachers could be prepared. Based on this premise, this study aims to investigate preservice and inservice science teachers' perception on their teacher preparation programs with a focus on the coherence and balance of program. For this purpose, 20 preservice and 39 inservice science teachers were participated. Selection form and open-ended form questionnaires were developed to survey science teachers' perception on their program. The results of study are as follows: Firstly, participating preservice and inservice science teachers perceived the coherence of their program as moderate. The most and least coherent category of program was 'planning & preparation' and 'professional responsibilities' respectively. Inservice teachers perceived the program less coherent than preservice teachers in all four categories. Secondly, participating preservice and inservice science teachers perceived that practical elements were deficient compare to theoretical elements in light of balance of the program. Lastly, participating preservice and inservice science teachers perceived that current science teacher preparation program was biased to test-driven curriculum, and four domains of the program (subject matter knowledge, pedagogical content knowledge, general pedagogical knowledge, and teaching practicum) need to be more strongly connected to secondary school context. Alternative ways to be more coherent and balanced science teacher preparation program were also discussed based on the research.

This study aimed to explore the saliences of formal school science and their influences on the attitude toward science communication through mass media. Saliences of school science are salient memories of school science which a perciever attends to selectively among various aspects of formal school science. Among saliences. external saliences refer to the sensory aspects of formal school science. and internal saliences refer to the observers' cognition. Attitude toward science communication through mass media constitute six scales; exposure. cognition. focus. belief. self perception of understanding. application. The questionnaire were developed and sample was selected by multi-stage stratified clustering. The sample size was 1,825. The data was analysed by correlation and multiple stepwise regression. Positive saliences were lab work and science teacher and negative saliences were lecture and exam/grade. According to the correlation and multiple stepwise regression analysis. saliences of the formal school science could account only a small part of the attitude toward science communication through mass media. Internal salieces could account the attitude toward science communication than external salience. Further studies on new models including attitude towards science are needed.

In this research, we quantified the environmental load while using and not using secondary resources. During the process of primary processed product of metal resources (copper, aluminum), we applied LCA technique and analyzed by dividing into 8 environmental impact categories that affect the environment. Furthermore, we analyzed the greenhouse gas that occur during the process of primary processed product domestically and globally according to the changes of each metal resource's recycling rate. Consequently, when producing 1 ton of copper using secondary resources, the environmental effects were found to be 6.09E + 01 person-yr/f.u. and 7.23E + 01 person-yr/f.u. Additionally, as the recycling rate increased both globally and domestically, the amount of greenhouse gas decreased. Producing 1 ton of Aluminum using secondary resources, the environmental effects were found to be 2.34E + 02 person-yr/f.u. and 3.01E + 02 person-yr/f.u. Moreover, as the recycling rate domestically decreased, the amount of greenhouse gas increased, however the globally was decreased.

The distribution on 88 taxa of wild orchids in the Korean Peninsula was investigated by the examinations of specimens and the distribution maps were presented. The species numbers distributed at each eight floral regions in the Korean Peninsula are as the followings; Gapsan Province 27 taxa, Gwanbuk 21, Gwanseo 13, Middle 37, South 39, Southern-coast 33, Jeju 64 and Ulleung 19. Most species (72.7%) of Korean wild orchids are found in the Jeju Island. Eighteen taxa of them are restricted to the island in the Korean Peninsula. Among Korean species, 30 taxa grow at evergreen broad-leaved forests, and 16 are northern elements distributed at high mountains or northern part. In terms of distribution, the Korean wild orchid species are classified into IUCN Red List Categories by a modified criterion for Korean plants. No orchid species included EX or EW categories is found in the Korean Peninsula. Ten species are designated to be in CR category; Cymbidium kanran, C. lancifolium, C. ensifolium, Cypripedium japonicum, Cyrtosia septentrionalis, Dendrobium moniliforme, Habenaria chejuensis, H. radiata, Neofinetia falcata and Sedirea japonica, of which C. ensifolium and H. chejuensis are regarded as CR species for the first time. On the other hand, 22 taxa are classified into EN category, and the following nine taxa are newly proposed to be EN species; Gastrochilus japonicum, G. fuscopunctatus, Gastrodia verrucosa, Habenaria flagellifera, Herminium lanceum var. longicrure, Chamaegastrodia sikokiana, Lecanorchis kiusiana, Neottia hypocastanoptica and Tipularia japonica.

This study was conducted to explore the latest trends in domestic research related to career development for nurses and present a theoretical approach and practical direction of career related papers in the field of nursing and health care. The subject of the study was articles regarding career development of nurses published in domestic journals from 2008 to 2017. The final 29 papers were found after searching the RISS and KISS databases for 'nursing', 'nurse', 'career', 'career development', 'career development program', and 'career management.' To analyze the overall trends, the analysis was reviewed by year, source, research design, and subjects, and content analysis was used to identify trends by topic. The results of content analysis were divided into career development and career development results as the upper categories. The subcategories of career development were divided into organizational career management, personal career management, and career performance. The subcategories of personal career management consisted of career exploration, career planning, career plateau, and career interruption. Organizational career management consisted of CLS development and application, CLS awareness survey, and career development model building. Career performance consisted of career commitment, organizational commitment, turnover intention, change after CLS application, career satisfaction, and career withdrawal intention. The most frequently discussed topics were career commitment among career performance. Therefore, the direction of nursing research related to career development requires integrated research that meets personal and organizational needs, and diversity in subject, research design and research theme is required.

Intellectual Property(IP) investment and its management are an key driver to create corporate value and intangible asset value through corporate's competitiveness. The purposes of this study are to survey capability of IP management and assess the effects of IP investment and its management on the separation into groups of intangible asset value. In order to attain those purposes of this study, sample companies were taken and categorized into three groups by the level of intangible asset value ratio, and data for IP investment such as R&D expenditure and advertising expenditure were collected from 90 manufacturing companies, and data for IP management capability about patent, design and brand were taken through survey. The final results showed as followed: First, IP management capability were generally not sufficient in the results of survey. Second, mean vector for the four variables were significantly different among three groups in multivariate analysis variance. Third, the order of their contribution to separating the groups were R&D expenditure, advertising expenditure, patent management, management of design and brand in canonical variate analysis. Fourth, R&D and patent management capability were significantly related to the separation of three groups, while advertising expenditure were not significant and management of design and brand were not sure of Significance in multinomial logit discriminant analysis. Fifth, exploratory power of the discriminant model were estimated by 53% in classification analysis. Finally, strategic policy for IP investment and its management should be taken urgently to create intangible asset value and to improve the capability of its management.
