  • The study investigates peer rating, one of the most commonly used sources of performance rating other than those of supervisors. On the whole, both field and laboratory studies indicate that peer assessment is a valid and reliable evaluation procedure, but on average, peer rating is not usually accurate. The aim of the investigation is to explore the relationship of beliefs and attitude about the performance appraisal system as well as a dispositional characteristic as self-monitoring with rating behavior. In particular, the study tests whether the relationship between rating context variables-appraisal self efficacy and appraisal validity- and rating behavior depends in part on the personality of the rater. Data from 445 undergraduate students are analyzed for hypotheses testing. The study finds evidences that the high on appraisal self efficacy and appraisal validity are more likely to affect discriminating rating tendency and to reduce rating level. Results also show that self-monitoring make the moderating effects between contextual factors and rating behaviors. Some implications, future research directions, and limitations are discussed.

  • The business value of IT has been the focus of the academic and business field in recent years, along with the massive IT investment. Unfortunately, those studies have not been able to demonstrate strong linkages between the IT investment and performance. The impact of IT investment on performance is an important research topic that needs to consider the role of key contextual factors and intermediate factors. This study develops an integrated model for IT investment, with the mediating effects of production/coordination performance towards firm performance. In addition, the model is moderated by some factors like ISP(Information Systems Planning), Business Planning alignment, top management support, IT education and training, and process innovation. The empirical result, based on the moderating regression analysis, indicates that the relationship between IT Investment and production/coordination performance is significantly positive depending on moderating factors. However, production/coordination performance is partially related to firm performance.

  • This study investigates speech perception in noise (SPIN) in Korean. A new type of Korean SPIN test was developed by adopting a similar format to the English SPIN test. The predictability effects, noise effects and their interactions were examined in order to verify the previous findings based on English. The data from 14 Korean adults collected with this new type of Korean SPIN test confirmed the previous findings: first, the participants' overall performance was better in low noise conditions than in high noise conditions. Secondly, there was a tendency for highly predictable words to be more accurately perceived than less predictable words especially in high noise conditions. The results were interpreted in such a way that the listeners actively used both types of information: acoustic information and contextual information in speech perception. When the acoustic property of the speech sound was degraded with noise, the listeners took advantage of the linguistic contextual information in their processing of the speech sound. The findings of this study conform to those of the previous studies based on the English SPIN test. In addition, a possible effect of the frequency of target word was also found, calling for further investigation in this field of research in Korean. Implications of the results were also discussed.

  • Science museums are platforms of PUS (public understanding of science). The purpose of this study was to explore the science communicators' competencies critical in interacting with visitors from the comparison of their training and professional development programs nationally and internationally. The managers running science communicators' programs and communicators themselves from six different national science museums and those from five different international ones participated in the structured survey. The data from surveys were compared among respondents to draw common and specific descriptions for communicators' competencies. In addition, the experienced exemplary science communicator, Ms. Park, participated in this study and the data from her observation field notes, her own developed science communicators' manual, and interviews were used to support the result. The contextual model of learning in science museums (Falk, 2006) was used to illustrate science communicators' expertise. National managers and science communicators showed difference in their perception about science communicators' roles, difficulties, and improvement for their competencies. Internationally, the managers and science communicators showed similar perception about communicators' competencies in terms of the contextual model of learning. It is highly suggested that practice-based science communicators' training and professional development programs must be offered on the basis of interaction between experienced and novice communicators as mentors and mentees systems.

  • The purpose of this study was to describe and understand the characteristics of morphological, contextual as relational aggression among 4-year old children during free play periods. The ethnographic methods included participants observation of children's play interaction behaviors, field notes, video taping and analysis of transcribed date. The results are as exclusion occurred by group power taking the relational attribute, including direct language, while the other would not be revealed easily other than being in line with real relation. Also as follows; proactive relational aggression was more frequently observed in girls, and their major strategies employed against someone they disliked were ignoring them, distorting play-rules, and so on. Major strategies of reactive relational aggression in girls were largely manipulative in nature, for example, 'threatrning their friend' and 'withdrawal of friendship'.

  • After World War II, Japan experienced a great political and social shift, which brought a concern of emerging public landscape in urban development. This paper analyses the management of the aesthetic intentions in urban design effort. We reviewed the development of various public installation of artworks concerning urban landscape aesthetics through its administrative process in chronological order. The monuments during the first decade marked a shift in emphasis from the militarism of the pre-war and wartime period to one of peace. However, some of the monuments and sculptures are not immune to controversy. This became an issue that could no be ignored by public officials whose responsibility was to place the sculptures while maintaining sensitivity to public opinion. As public administrators began to consider the possibility that sculptures may contribute to improving public amenities, the contextual concepts were basically ignored. Some of the programs in 1970s began to show more respect to the context, while other programs in this period expressed more interest in educational aspects of sculptures in the public spaces. Urban development projects also seek to introduce artworks integrated to their urban design concepts in 1990s. Generally, the administrators responsible for these programs were rarely trained in any relative field study other than public administration. Installing sculptures tended to be considered as part of public works projects on the level of urban planning and construction. The general public is basically removed from participating in the critical decisions that actually impact their lives in relation to the artworks. In conclusion, public art in japan has unique social and historic background both in its advantages and disadvantages. Issues pertaining to art in public spaces have evolved over the decades as the term "sculpture pollution" began to appear by the mid 1990s. most of the problems originated in either the lack of monumentality, contextual consideration, quality, or public participation. From another point of view, these programs played great roll in the development of modern Japanese sculpture and patronizing process, and the creation of new urban landscape with aesthetic value. In this sense, they must be considered as successful and noteworthy examples of cultural administration and urban design policy.

  • The bush warblers (Cettia diphone) have been recognized to possess two types of songs: a normal song that plays roles in attracting mate and territorial defense, and an anomalous song. The present study suggests that the anomalous song functions as an alarm signal as well as other unknown signals. Field observations and playback experiments on the anomalous song of bush warbler were conducted in order to investigate the contextual information that occurred between sender and receiver. In the field observation, the males frequently emitted anomalous songs to potential predators. The males responded with an anomalous song to stuffed potential predators. The distance from where the anomalous song occurs to the stimulating source varied depending upon the kinds of stimulus. The males of bush warbler possibly show different responses to the anomalous song depending on the level of danger. When the anomalous song was played back to terrestrial males and females, no distinctive behavior was observed. The anomalous song may be sung to defend the territory against predators or to distract invaders from the nest and female because the male and female behaviors were related with the anomalous song and its phonetic characteristics.

  • In this study we analyzed and interpreted the phenomenologlcal characteristics and meanings of water space in religious architecture through field studies and phenomenologlcal approaches, focusing on the religious architecture Introducing water space in contemporary architecture. The phenomenological experience elements of the research ate light, time, place and context. As the results of this study, first, light as a phenomenological element not only induces a contrast and change between light and the shadow in architectural space and various changes of light in inner space, but also operates as an element which expresses building features outward with time. Second, time as a phenomenological perception experience makes us feel changes of the environment and physical properties and experience space visually and physically. The continuity of time shows the change of a day, night and daytime and seasons. Third, water space makes the sense of place more remarkable, connected closely with surrounding nature In outer space, and creates a new space. Fourth, water space is a contextual element which harmonizes with surrounding environment by connecting surrounding natural environment with architectural space. Fifth, water space in religious architecture is a symbolic and central element, and emphasizes the atmosphere of architectural space. In addition, it makes the people who experience water space perceive the place by triggering sensitive response.

  • This study explored the meaning of beginning teachers' first-year experience in an eco child educare center. Participants were 4 teachers at survival stages of teacher development; they had had the same preservice experience. Data were collected by semi-structured in-depth interviews, participant observation, researcher's field notes, and document collection. Five themes emerged as first year teachers' struggles and strategies for survival : (1) caring for children's daily lives vs. responsibility for formal education, (2) planned lessons vs. ease in teaching, (3) agreement or disagreement on philosophy of running the education program, (4) paradox of teacher empowerment, (5) overcoming struggle through voluntary peer supervision. These results indicated that beginning teacher' experiences at the survival stage varied by contextual and personal factors.
