Currently, the government has made a lot of efforts to improve construction productivity but there are few studies which measure between safety perception level and productivity in the South Korean construction industry. Therefore, the objective of this study is to analyze correlation between safety perception level of domestic construction companies and construction productivity. To achieve the objective, first, the concept of safety perception level was defined. Second, the safety perception level and construction productivity were investigated in the case projects. Third, correlation analysis was conducted between safety perception level and productivity. As a result, it was concluded that a high level of safety perception of executive and manager would increase construction productivity. In addition, To improve the safety perception level in the construction company, it is suggested that the provision safety resources for managements and the equal communication system between workers and managements and the development safety education tools considering the worker's experience. In the future, these findings can be utilized to develop future evaluation tools for a safety perception level in domestic construction company.

Purpose: The purpose of this study was to examine the mediating effect of self-perception on the relationship between body image and depressive symptoms in middle school adolescents. Methods: This study performed a pathway analysis with a sample of 284 adolescents recruited from three middle schools. Self-reported questionnaires consisted of items regarding body image, self-perception, and depressive symptoms. Results: Body image, self-perception, and depressive symptoms showed a significant correlation. Self-perception was directly affected by body image and depressive symptoms were not affected by body image. The mediating effect of self-perception on body image's impact on depressive symptoms was confirmed. Self-perception had a significant indirect effect on depressive symptoms, which means that self-perception has a full mediating effect on body image's impact on depressive symptoms. Conclusion: The effect of body image on depressive symptoms was fully mediated by self-perception in early adolescents. It suggests that self-perception needs to be considered when providing nursing interventions for adolescents.

Purpose : There is a lack of research on this field in the Republic of Korea, especially those that have seen the effect of interaction between transcranial direct current stimulation and computerized cognitive rehabilitation therapy. This study divided 30 dementia patients into a treatment group, which received transcranial direct current stimulation and computerized cognitive rehabilitation, and a control group, which received pseudo-transcranial direct current stimulation and pseudo-computerized cognitive rehabilitation. This study evaluated the effects of these treatments on the visual perception, cognition functions, and daily activities of dementia patients. Methods : Fifteen subjects were allocated to the treatment group and the other 15 subjects were allocated to the control group. Treatments were given at intervals of five sessions per week (30 minutes per session) for six weeks (30 times in total). This study used the Neurobehavioral Cognitive Status Examination (NCSE) to examine cognitive functions, MVPT to evaluate visual perception, and FIM to test daily living activities before and after applying the treatments. Results : The results of this study showed that cognitive functions, visual perception, and daily living activities significantly (p<.05) improved after the intervention in the treatment group and the control group. The changes in cognitive functions, visual perception, and daily living activities due to the treatments were significantly different between the groups (p<.05). Conclusion : The results indicated that transcranial direct current stimulation and computerized cognitive rehabilitation therapy improved visual perception and daily living activities by increasing cognitive functions. Consequently, it was found that the simultaneous application of transcranial direct current stimulation in conjunction with a computerized cognitive rehabilitation program was an intervention method that could positively affect the visual perception, cognitive function, and daily living activities of dementia patients. Based on the results of this study, the study of arbitration protocols for demential will have to be more active.

Visual perception is ability that analyze visual information about things accepting through eyes in central nervous system. That is, it is ability that recognize and discriminates a visual stimulus, and analyzes by combining such stimulus with previous experience. At today, work which clears visual perception obstacle's cause through visual perception test and grasps all special quality of visual perception obstacle's is used method of treating that improve visual perception obstacle by visual perception training program. Present, visual perception test tools using the paper and pens are used mainly on psychological consultation of welfare facilities and education for the handicapped or occupational therapy, but a lot of problems are discovered in it. Therefore, purpose of this paper is to develop prototype of web-based visual perception test program that can construct to database to solve existing problem, and to design graphic item. As a result, classified measurement pattern that can diagnose visual perception by three, and illustrated development direction of graphic item for examination with this. Also, extracted check list item that should consider for design and construction of visual perception test program and the variable for feasibility study of believability, and presented process for prototype development.

This study aimed to identify the development pattern of final stop consonant perception using the gating task. Sixty-four subjects participated in the study: 16 children aged 4 years, 16 children aged 5 years, 17 children aged 6 years, and 15 adults. One-syllable words with consonant-vowel-consonant(CVC) structure, mokㄱ-motㄱ and papㄱ-patㄱ were used as stimuli in order to remove the redundancy of acoustic cues in stimulus words, 40ms-length (-40ms) and 60ms-length (-60ms) from the entire duration of the final consonant were deleted. Three conditions (the whole word segment, -40ms, -60ms) were used for this speech perception experiment. 48 tokens (4 stimuli ${\times}3$ conditions ${\times}4$ trials) in total were provided for participants. The results indicated that 5 and 6 year olds showed final consonant perception similar to adults in stimuli, papㄱ-patㄱ and only the 6-year-old children showed perception similar to adults in stimuli, 'mokㄱ-motㄱ. The results suggested that younger typically developing children require more acoustic information to accurately perceive final consonants than older children and adults. Final consonant perception ability may become adult-like around 6 years old. The study provides fundamental data on the development pattern of speech perception in normal developing children, which can be used to compare to those of children with communication disorders.

Object:This study was to investigate the difference of speech perception ability in schizophrenic patients, and depression patients in order to explore trait-dependent speech perception ability of each disorder. Methods:The speech perception ability was assessed with masked speech tracking test(MST) in schizophrenic patients(N=31), depression patients(N=25), and normal controls(N=21). The continuous performance test(CPT) and sentence repetition test(SRT) were also used for assessment of attention and working memory. Results:The schizophrenic patients showed significant impaired MST performance, compared with depressive patients and normal controls. The performances of CPT and SRT were also more impaired in schizophrenic patients. The difference of MST performances between two patient group was cancelled out after consideration of differences in CPT & SRT performances. Conclusions:These results imply that schizophrenic patients have the impaired speech perception ability compared with depressive patients and normal controls. But speech perception ability was significantly influenced with CPT and SRT. For evaluation of pure speech perception ability, the more elaborate controlled study that excluded factors such as attention, working memory and intelligence is needed.

Purpose: The purpose of this study was to explore perception of clinical experience between the initial and final practice and to explore changes in the perception of clinical experience. Method: The study used a Q-method to measure perception of clinical practice. Thirty-six statements made up the finalized Q-sample. The P sample used thirty three nursing college students from K university. The initial collection was done in the first semester of their junior year and second collection was done in the last semester of their senior year. The Q-sorts by each student were coded and analysed with the Quanl PC program. Result: Many students classified as having the perception type 'alienation of ideal and reality' or 'perception of limitation of ability' in the initial clinical practice changed to the type, 'active participation' by the final clinical practice. Further, in the initial clinical practice, part of 'active participation' and 'perception of limitation of ability' changed to 'alienation of ideal and reality'. Conclusion: This study shows that perception of their clinical practice by student nurses changed in a positive direction through clinical experience and that this fact was related to the level of satisfaction with nursing. The knowledge and understanding obtained in this research provide insights for nursing faculty and students involved in nursing education.
