Objectives: Chronic diseases (CDs) continue to increase due to advances in medicine and increase in lifespan, affecting quality of life and resulting in economic loss through treatment costs. This study addressed the perception characteristics of the effectiveness of Korean medicine (KM) based on the existence of a CD to determine the national preference for KM treatment. Methods: Using data from the 2017 National Survey of KM Usage, we evaluated the perception on treatment effect of 16 diseases by dividing them into the CD group and the non-CD group. Response reliability was verified by applying the chi-square test (χ2-test) analysis method of the Statistical Package for the Social Sciences (SPSS) statistical program. Results: The analysis of the perception on effectiveness of KM for patients with CD (n = 1,050, 21.0%) and for patients with non-CD (n = 3,950, 79.0%) showed an overall similar trend for all the 16 diseases. The response rates of having some treatment effect were high for nine diseases namely, disc-related disease (CD: 70.7%, non-CD: 73.1%), osteoarthritis (CD: 72.3%, non-CD: 72.4%), frozen shoulder and shoulder pain (CD: 79.6%, non-CD: 81.4%), back pain (CD: 84.6%, non-CD: 85.0%), sprain (CD: 84.8%, non-CD: 84.1%), facial nerve paralysis (CD: 73.5%, non-CD: 71.7%), stroke (CD: 66.2%, non-CD: 62.8%), digestive disease (CD: 53.3%, non-CD: 50.0%), and common cold and rhinitis (CD: 44.7%, non-CD: 44.8%). Conclusion: The present results found that there was little difference in the perception on effectiveness of KM for each of the 16 diseases in patients with CD and non-CD, however, 70% or more of the respondents recognized some treatment effect on musculoskeletal disorders, regardless of the existence of CD. Preferential political support for KM treatment of chronic musculoskeletal disorders is recommended.

This study attempted to analyze the consonant perception ability and errors and to verify compatibility items for hearing impaired children wearing hearing aids and cochlear implants using the Phoneme Perception Test for School-Aged children (PPT-S). As a result of the study, it was found that children with hearing impairments have more difficulty in perceiving final consonants than initial consonants. The hard type of PPT-S, in which the articulation method and articulation place of the target and foil words are similar, felt more difficult than the easy type. Among the initial consonants, the incorrect response rate for aspiration sound was higher. In the case of final consonants, the incorrect answer rate for 'ㄷ' and 'ㅁ' was relatively higher. There was no significant difference in the percentage of correct response rate according to the gender of the speaker. The above results can be usefully used as basic data for standardizing of PPT-S and evaluating the intervention effects before and after hearing rehabilitation with hearing impaired children.

On the distribution in the stroke 50 patients, For the majority group were male in sex, sixty inage, middle towns people in residence. 2. On the comprehensive GARS scale scores, It marked the higest scores thirty at age, merchandise or salesman on jobs, a city in residence. There was no signigicant difference in mean GARS Scales scores between males and females group, the left hemiplegia and the Rt hemiplegia. 3. On the comprehensive GARS Scale tests, Overall glogal stressor(G8) and sickness stresor(G4) marked the highest scores of all GARS Scales. 4. On the comparative assessment of each group's stress reponse test scores, zung-bu(中腑) was showed higher scores than the other group in oriental diagnosis and hemorrage was showed higher scores than the other group in western medical diagnosis. 5. On the comprehensive assessment of each group's stress reponse test scores, aphsia(不語) marked the highest scores in another disphagia group's. It marked the highest scores in another group's that banshinbulsoo(半身不遂) as regards as hemiplegia generally. Standing disability is the higher scores than another group's walking alone or assist, and standing alone. 6. Secondary attack is the highest scores of all reattack stroke on the stress repones test. 7. Comparing and analyzing the GARS Scale total scores and GARS Scale subject fator at stroke, we found that sickness stressor and fininial stressor is showed the highest correlated to stress response fowlloing stroke. With those results, we can see that functional impairment following stroke is correlated to stress perception and reponse. In the furture studies using, we hope that the findings the study would have clinical relevance to the psychosocial adjustment and total rehabilation of stroke patients.

In this paper, to analyze the perception and response strategy of Korean ship owners on Global Sulphur Cap 2020, examined the IMO environmental regulation status focusing on MARPOL Annex VI regulation about air pollution prevention, technological measures to reduce SOx emission, shipping industry and management status of Korean ship owners. First of all, the questionnaire was conducted for Korean ship owners after selecting the evaluation factors. The purpose of this study was to investigate the difference of the perception and response strategy of Korean ship owners by corporation size and main vessel type using frequency and cross analysis. It is confirmed that various researches on SOx emission reduction have been carried out from various points of view at home and abroad. In this study, existing studies related to technical factors for regulatory response and economics analysis were examined and evaluation factors were selected. As a result of analysis, it is found that large-sized shipping companies are more prepared for regulatory response than small and medium-sized bulk carrier owners. There were similar perception and the direction of response strategy about the impacts by corporation size and main vessel type. In about two years to be implemented in 2020, It is necessary to find an appropriate response strategy based on the support policy of the government and related organizations and the systematic analysis of the ship owners. Through this study, although the difference between the perception and response strategy of the ship owners by corporation size and main vessel type was understood, it was found that there were limitations on specific response strategy and corporate data collection. In future research, we should overcome the limitations of this study and conduct an in-depth study.

Human perception is an outcome of the influence of various factors rather than objective reflection of external environment. Among the factors, action-specific perception is a phenomenon where perception changes in terms of one's ability to act on the environment. Previous research reported contradictory results regarding whether action-specific perception occurs during performance or after performance due to memory distortion or knowledge about performance results. In this research, we conducted three experiments to determine when action-specific perception occurs. Participants threw darts at different distances and reported perceived size of targets in each trial. The results showed that, in Experiments 1 and 2, participants perceived targets larger when they hit than missed the targets, and the effect was greater when the targets were not visible after each throw. However, because participants had knowledge about the results of their throws, there could have been bias in participants' responses. In Experiment 3, where this possibility was excluded, we also obtained action-specific perception, and therefore concluded that action-specific perception occurs during but not after task performance.
