  • The concrete track system on domestic urban transit has being constructed since 1974. Because a maintenance and repair of concrete track system is convenient, a construction is increased. The concrete track system on domestic urban transit is constructed 71.8% of total track system length and constructed variously, for example STEDEF, LVT, ALT and so on. Recently, railway noise is issued as environment problem. The method for mitigation of urban transit noise is required. In this study to study noise characteristics on concrete tracks we measured noise by concrete track types and analysis the result.

  • As considering a comparison study of the structure of mind and psychologic type of C.G Jung to Ji-In-Lon and Sa-Sang constituition of Lee Je Ma, I've got the following conclusion. 1. The study of the structure of mind of Jung and Ji-In-Lon of Lee Je ma have a important meaning to each theory of type of men. They developed their own peculiar theory of type men by the analysis of the mind of men. 2. Jung explained the organization of recognition by four phase theorical structure; consciousness, personal unconsciousness, collective unconsciousness, self. Lee Je Ma explained the organization of recognition by four phase theorical structure;Sa, Sim, Sin, Mul. And theory of type of men, Jung established four type; Tae-Yang-In, Tae-Um-In, So-Yang-In, So-Um-In, They all established the four phase structure, which have things in common. 3. Jung studied the consciousness and unconsciousness and Lee Je Ma studied the Sung-In, Eui, Ye, Ji, and Sim-Yock-Bi, Bak, Tam, Na. I think they have a close relationship. And I think there is relationship between consciousness, unconsciousness to Gun-Ja-Ji-Sim, So-In-Ji-Sim. 4. I think there is thought of relationship between Lee Je Ma's Dae-Dong, Gak-lip, Hang-gi-ji, Hang-gi-hang and Ho-sun, Oh-ak, Sa-sim, Tae-hang and relationship of internal organ's size to Jung's the first function, second function, third function, fourth function. 5. I think the relationship between the type of Jung;thinking type, feeling, type, sensation type, intuition type to the type of Lee Je Ma; Tae-Yang-In, Tae-Um-In, So-Yang-In, So-Yang-In, So-Um-In needs more study.

  • The purpose of this study is to develop a convergence inpatient medical service patient experience management model(IMSPEMM) that can help in the management strategy of a medical institution to create a patient-centered medical culture. Using the original data from the 2018 Medical Service Experience Survey, 593 people with medical services inpatient(MSI) over the age of 15 were analyzed. By using the decision tree model, we developed a prediction model for overall satisfaction(OS) with the inpatient medical service experience(IMSE) and the intention to recommend patient experience(RI), and were classified into 4 and 7 types. The accuracy of the model was 68.9% and 78.3%. The OS level of IMSE was the nurse area and the hospital room noise management area, and the RI decision factor was the nurse area. It is significant that the IMSPEMM for MSI was presented and confirmed that the nurse area and the noise management area of the hospital room are important factors for the inpatient experience. It is considered that further research is needed to generalize the IMSPEMM.

  • In this paper, we analyzed the requirements for the application of UAM, a new concept to solve the traffic congestion in large cities. First, the current domestic and foreign status of research and development related to UAM was investigated and the pros and cons and the time required for each mission radius were analyzed for various configurations of aircraft being commercialized. In addition, in order to analyze the market acceptance of the UAM, the individual's consciousness and reliability requirements were identified and safety requirements were analyzed through accident rate data for each aircraft type. Because it operates in a densely populated urban area, requirement analyses on noise and exhaust, which are environmental factors that can affect the community were performed, and requirements related to aircraft performance, certification standards, and airworthiness standards of FAA and EASA were also analyzed.

  • The purpose of this study is to examine differences in mental health indices such as self-compassion, trait anxiety, and depression, and color preference based on Sasang Constitution type. This study also explored the relationships among self-compassion, trait anxiety, and depression. 205 adults were surveyed for participants of this study. A Two-Step Questionnaire (TS-QSCD) was conducted to diagnose Sasang Constitution such as Tae-yangin, Tae-yinin, So-yangin, and So-yinin. Also, scales for self-compassion, trait anxiety, depression level, and color preference were utilized for measures. The results showed that among Sasang Constitutional groups, Ta-yangin had a higher level of self-compassion and lower trait anxiety than So-yinin. Furthermore, in relationships among mental health indices, trait anxiety and depression tendency were lower with higher self-compassion. No significant differences were revealed in depression level and color preference based on Sasang constitution. Finally, implications of this study for mental health were suggested and limitations were discussed.

  • This study attempted to develop repetitive impact sources similar to real-life floor impact noise and to find an assessment approach corresponding to this new impact source. The necessity for the development of the new impact source arises from the fact that issues related to floor impact noise in actual residential buildings mainly stem from children running. However, the standard impact sources which have been used for measuring and evaluating floor impact noise are of single-impulse type, which differs from the actual problematic impact sources. The study encompassed 18 evaluation items, and the results suggest that items applicable for assessing floor impact noise include psychological effects (annoying, becoming angry), disturbances to daily life (interference with sleep, disruption of relaxation), and physiological effects (elevated blood pressure). These items can be employed individually and, depending on the type of evaluation for floor impact noise, can be selectively utilized. By doing so, more comprehensive evaluations of auditory experiments in laboratories or assessments of residential noise in living environments related to floor impact noise could be conducted.

  • In Sasang constitutional medicine, the classification of Sasang constitutional types (Tae-Yang, Tae-Eum, So-Yang, and So-Eum) is important for the treatment. There are some problems with the methods used for classifying Sasang constitutional types; old methods such as pulse-palpation are not considered objective and recent methods such as immunohematology are considered expensive, painful and time-consuming. To overcome these problems, a body measurement and finger prints analysis were performed. The purpose of this study was to determine whether the palm prints and the palm creases could be helpful in classifying Sasang constitutional types. Thus, we looked for characteristics of the palm prints and the palm creases according to Sasang constitutional types. Before analyzing the palm prints and palm creases, 760 Korean (465 males, 295 females) were surveyed using two kinds of questionnaires for classifying Sasang constitutional types. As there were no Tae-Yang individuals, we were only able to identify the characteristics of the palm prints and the palm creases for Tae-Eum (288 persons), So-Yang (193 persons), and So-Eum (279 persons) individuals. In this study, the terminal points of D, closed crease, and open crease seemed to be helpful in classifying Tae-Eum and So-Eum individuals. Terminal point 11 and closed crease were frequent in Tae-Eum individuals; whereas, terminal point 7 and open crease were frequent in So-Eum individuals. Therefore, the palm prints and the palm creases seem to contribute to the classification of Sasang constitutional types.

  • Twelve Japanese students living in South Korea have been examined for their perceptual identification of an initial consonant in Korean syllables with or without a white noise. A confusion matrix was then subject to analyses of additive clustering, individual difference scaling, and probability of information transmission, the results of which were also compared to those of South Koreans. The Japanese in the present experiment confused /다/and/타/ most frequently, followed by /가/ and /카/, /자, 차, 짜/, /타/ and /따/, and so on. The results of additive clustering analysis of the Japanese significantly differed from those of the South Koreans. Individual difference scaling revealed dimensions of sonorant, aspiration and coronal. While South Koreans showed binary values on aspiration and tenseness dimensions, the Japanese did continuous values on such dimensions. An information transmission probability analysis revealed that the Japanese participants could not perceive very well such larynx features as tenseness and aspiration compared to the South Korean participants. The former group, however, perceived very well place of articulation features such as labial and coronal. The present results suggest that an approach dealing with structures of base representations is important in understanding the phonological categories of languages.

  • This study researched those universities for which fence opening and greening projects are being conducted by Seoul city. The forms of opened fences at 24 universities which have accomplished this project were classified into several types for each type of university, representative cases with many diverse facilities and active users were selected and investigated. The study was carried out using methods of field observations, literature review, and surveys. To maintain the confidentiality of the collected questionnaire analysis, the analysis of each type's usage frequency, overall satisfaction and a regression analysis with space environment and facilities, a one-way ANOVA for was used to validate the difference between types regarding satisfaction with the project. The results of usage type analysis were found to agree with the 3 analysis criteria-- installation location, user characteristics, and usage purpose--which were the legislative concepts. In overall satisfaction with facilities, it appeared that except for Seoul Women's College of Nursing with its rural district neighborhood type park, users were satisfied: with the small urban neighborhood park of Methodist Theological College, Konkuk University's small urban square park, and Sejong University's green space small city park. In general, users appeared to not have satisfaction with such features as fountains / hydroponic facilities, fitness facilities, and square facilities, which should be taken into consideration when pursuing further opening and greening projects. Regarding full satisfaction with the space environment, it was found that users were not satisfied with Seoul Women's College of Nursing's rural district neighborhood-style park, whereas they were satisfied with Methodist Theological College's small urban neighborhood park, Konkuk University's small urban square-style park, and Sejong University's green space small city park. In addition, it was shown that facilities use, convenience and privacy of the four parks were largely unsatisfactory for users, and that the small city parks located at roadsides were unsatisfactory regarding noise level, both of which should be most highly considered when conducting similar projects in the future.
