The assessment of perceived naturalness aims to elucidate the human perception and explain the interaction between natural environments and humans. The perception of ecological assets that exhibit distinct characteristics within a specific region can manifest in various representations. Based on the users' perceptions and interviews regarding ecological assets, this study assessed the perceived naturalness from a cultural services perspective. Specifically, the discussions on Ansan City's ecological assets and revolved around the inherent value of naturalness in dimensions, such as the necessity for conservation and the sustainable development of ecological assets, the perception of ecosystem benefits, the representativeness as a local asset, and usability. Subsequently, the Q method was employed to present 25 representative ecological assets to 25 users. As a result, user groups with different value systems for each question were identified, and hypothetical personas for cultural service enjoyment were distinguished. The most representative persona among the 25 users was identified as AWP (a type that values the conservation of aquatic ecosystems, prefers waterfront landscapes, and enjoys walking). Since perceived naturalness is conceptually similar to the "benefits perceived by users" in evaluating ecosystem services, it can provide more practical evaluation criteria for cultural services.

This study was done to describe health behavior and determine affecting factors in Korean adults, based on the Health Behavior Assessment tool. The subjects were sample of 298 adults from five cities. The instrument for this study were Health Behavior Assessment tool (30 items, 4 scale). Frequency, percentage, t-test, ANOVA, cluster analysis with SPSS program were used to analyze the data. The results of the study are as follows ; 1) The average item score for health behavior was 2.56, the highest score on the subscale was limitation of liking(M=3.16), followed by stress management (M=2.98), nutrition(M=2.82), energy conservation (M=2.67). 2) A significant difference between age, sex, perception of health, and health behavior were found. 3) Pattern of health behavior among Korean adults focused on stress management in order to obtain emotional stability, and balance and harmony in dietary life, and energy conservation. Patterns of health behavior in Korean adults is unique in each individual. Therefore nursing intervention skill for health promotion have to be developed based on the health behavior in each individual.

Much research attention has been directed to identify how native speakers perceive non-native speakers' oral proficiency. To investigate the generalizability of previous findings, this study examined segmental, phonological, accentual, and temporal correlates of native speakers' evaluation of L2 Korean proficiency produced by learners with various levels and nationalities. Our experiment results show that proficiency ratings by native speakers significantly correlate not only with rate of speech, but also with the segmental accuracies. The influence of segmental errors has the highest correlation with the proficiency of L2 Korean speech. We further verified this finding within substitution, deletion, insertion error rates. Although phonological accuracy was expected to be highly correlated with the proficiency score, it was the least influential measure. Another new finding in this study is that the role of pitch and accent has been underemphasized so far in the non-native Korean speech perception studies. This work will serve as the groundwork for the development of automatic assessment module in Korean CAPT system.

An improved algorithm for image quality assessment is presented. First a simple model of human visual system, consisting of a nonlinear function and a 2-D filter, processes the input images. This filter has one user-defined parameter, whose value depends on the reference image. This way the algorithm can adapt to different scenarios. In the next step the average value of locally computed correlation coefficients between the two processed images is found. This criterion is closely related to the way in which human observer assesses image quality. Finally, image quality measure is computed as the average value of locally computed correlation coefficients, adjusted by the average correlation coefficient between the reference and error images. By this approach the proposed measure differentiates between the random and signal dependant distortions, which have different effects on human observer. Performance of the proposed quality measure is illustrated by examples involving images with different types of degradation.

The Korean government adopted the integrated stream water management policy recently with growing perception that natural disasters and pollution in Korea have been due not only to such human factors as urbanization and industrialization, but also to the policy of functionally separated management of irrigation, flood control and ecological management. Contrary to its good intention, research result shows that it is not realistic to expect that this new integrated policy in Korea will work well. In order to be an effective policy and program evaluation, this paper suggests that evaluation indicator on related programs and projects should be made through bottom-up process. For example, environmental benefit should be taken into account rather than just economic benefit, and cultural and social characteristics in the project region should be also considered seriously.

The government should establish internationally harmonious regulations for effective import and export of necessary resources to other countries. However, the use and the number of pesticides used for the same purpose on same crops are depending on the soil and the climate where the crops are grown. Therefore, if internationally harmonized standards are difficult to establish, it is mandatory to conduct a risk assessment based on scientific data to reflect the domestic situation in order to avoid trade friction or conflict between countries. The government is preparing the implementation of a more regulated PLS (positive list systme) than the existing pesticide management system for safer pesticide management reflecting the recent increasing imported food, changing dietary habits, and changing climate. In order for effectively safe and scientific management of pesticides, the government should strive to communicate with consumers properly and the perception of pesticides by consumers should also be changed.

This paper adopts the psychoacoustical methodology to evaluate the acoustical qualities of rooms and describes some of the results of an attempt to develop such a test. In order to investigate the effect of hall response to subjects, a subjective experiment was performed in artificially simulated sound fields. Pairs of sounds having differences in duration/frequency were presented to a subject and the subject's responses were recorded. The stimuli were varied through an auralization system that simulates three different rooms. It was found that duration/frequency discrimination is influenced by the room conditions and that these discrimination procedures may form the basis for assessment of room acoustics.

This paper discussed the limit of existing safety controls where the use of land around hazardous industry. There is a gap between engineering evaluation of acceptable criteria for loss reduction and risk exposure to the areas of high risk outside plants from the aspects of risk perception. The paper performed how land use safety could be designed between the density of uses with the duration of risk exposure by type of land use. It concluded the needs of multi-dimensional presentation for an appropriate risk controls on existing and future land use safety.

Now, more than any other time, education experts in Korea are focusing on the importance of reading. Based on this circumstance. it is necessary to introduce and develop reading assessments in the library and information science. The research introduces reading assessment tools from a psychological standpoint for the purpose of increasing reading efficiency through literature reviews. There are four categories reading attitude, interest, motivation and perception on reading. Also the research presents the suggestion to make a new reading assessment tool at a later time. When developing reading assessment tools from a psychological standpoint, it is necessary to establish the items through which how a student feels himself or herself as a reader, and subsequently how teachers, parents, and friends feel the student as a reader. Besides establishing of these appropriate items. a developer should provide directions for administration and interpretation.

Background: The presence of visuospatial impairment can make patients slow functional recovery and impede the rehabilitation process in TBI patients. Objective: The aim of this study is to investigate effects of prism adaptation treatment for functional outcomes in patients following traumatic brain injury. Methods: The subject received prism adaptation treatment for 2 weeks additionally during traditional rehabilitation for 4 weeks. The Patient has prism adaptation treatment while wearing wedge prisms that shift the external environment about $12^{\circ}$ leftward. The patient received 10 sessions, 15-20min each session. Outcome measures were visuospatial deficit(line bisection, latter cancellation), Visual and spatial perception(LOTCA-visual perception and spatial perception), motor function of upper extremity(FMA U/E; Fugl-Meyer motor assessment upper extremity, ARAT; Action research arm test), balance(BBS; Berg Balance Scale), mobility(FAC; Functional ambulation classification) and functional level(FIM; Functional independent measure). All Assessments took place on study entry and post-treatment assessments were performed at discharge from the hospital. Results: After prism adaptation, the visuospatial impairment scores improved as indicated in the line bisection(-15.2 to -6.02), latter cancellation(2 to 0) and LOTCA- spatial perception scores(7 to 9). The upper motor function improved as indicated in the scores of affected FMA U/E(21 to 40) and ARAT(4 to 22). Ambulation and balance improved as indicated in the BBS scores(25 to 38) and FAC scores(0 to 4). ADL function improved as indicated in the FIM total scores 54 to 70(motor 34 to 61, cognition 20 to 29). Conclusion: Prism adaptation did improve functional level such as motor functions and ADL abilities in TBI patient. Further research is recommended.
