Since walking and physical activity are critical for older adults to maintain their health, it is important to provide neighborhood environments which encourage their walking in daily life. The purposes of the present study were to investigate walking activity patterns of older people in an urban setting and to identify environmental correlates with walking of older adults. This study examined spatial and temporal patterns of physical activities, environmental barriers and motivations, satisfaction levels and demands on the physical environment. In-depth interviews with older adults over age sixty residing in Seoul metropolitan areas revealed that most respondents have a positive perception on walking in daily life, and many of them walk regularly for their health. A primary purpose of walking for older adults was exercise for health rather than transportation. The study result demonstrated that parks and trails were the most preferred places for walking by older adults, and there is an association between frequency of walking participation and access or convenience to parks, traffic safety, and street lights. Most respondents were concerned about traffic safety when they walk in their neighborhoods due to traffic speeds and unsafe streets. Lack of separate sidewalks or benches, stairs and slopes were barriers to older adults' walking habits. This data suggests that the promotion of walking behavior among older adults, some level of public health action, and community support are needed to ensure safe physical environments within communities.

In this study, the objective of this study is to verify the effects between lecturer's capability, education program, education service, and physical educational environment factors, and university students' interest in and attitude toward mathematics. A survey was conducted on 228 male and female students in science and engineering majors attending universities in the Pusan metropolitan area, and empirical analysis was conducted using the SPSS 26.0 program. The research results are as follows. First, among the characteristics of college mathematics maker classes, instructor competency (β=.349, t=6.380, p<.001), educational program (β=.361, t=5.650, p<.001), and physical educational environment (β=.196, t=3.281, p<.01) had a significant positive (+) effect on college students' interest in mathematics. Second, the factors of interest (β=.349, t=6.380, p<.001) in college mathematics maker classes were found to have a significant positive (+) effect on college students' attitudes toward mathematics. Third, among the characteristics of college mathematics maker classes, instructor competency (β=.340, t=6.365, p<.001), educational program (β=.352, t=5.559, p<.001), physical educational environment (β=.226, t=3.537, p<.01) was found to have a significant positive (+) effect on college students' attitudes toward mathematics. Through the results of this study, it was concluded that when the level of education program and teaching ability of the university mathematics maker class are high and the physical educational environment is excellent, it can have a positive effect not only on the university student's attitude towards mathematics but ultimately on the attitude of mathematics.

Innovation clusters have developed a key policy indicator in the level of national competitiveness. Many countries have enhanced their regional competitiveness by fostering innovation clusters at the national, regional, and industrial level. In Korea, the cluster policy has been introduced and employed to a national policy as a means of facilitating a regional innovation for over two decades. This study analyze that the changes of the institutional, physical and social configurations of innovation clusters. In particular, we identified configuration factors which are the growth and development impact factors of individual subjects from the case study of the Daedeok Innopolis. Also, the factors are derived and identified priorities of the configuration factors by using Analytic Hierarchy Process (AHP) method in long term perspective. As a result, we provide the growth of individual innovation subjects, as well as the growth of the cluster caused by the cyclic causality among configuration factors. Also, we can suggest that innovation policy from priorities of configuration factors for innovation cluster which the priorities have lessons for policy implementation and new cluster policy agenda in Korea, in specific, the Daedeok Innopolis.

The purpose of this study was to investigate the relationship between the determinant factors of visitors' satisfaction and behavioral intentions to the Shincheon stream in Daegu city. It was found that ecology of the Shincheon stream, signals about ecology, and physical facilities positively influenced overall satisfaction. Physical facilities more positively influenced overall satisfaction. The overall satisfaction positively influenced behavioral intentions. For the future studies, it is necessary to do research visitors' satisfaction with more diverse factors of satisfaction and longitudinal studies about visitors' satisfaction based on seasonally different visitors.

Recently, The attack on the USB and network are increasing in many domestic infrastructure. These attacks are the most independent of insider intention, caused by the Anthropogenic Manipulation. These attacks are Anthropogenic Response Measures for Physical Security. and Representative Technology has CCTV, Access Control System, Sensor Technology. However, Physical Security, it is represented by several Product family according to the Market, has become an obstacle but rather a variety of Physical Security Technology Development and Application. As the Anthropogenic Attacks have occur continually in the network, it need to the proper Physical Response Techniques in this situation. Therefore, In this paper, we will find out about the awareness and demand trends of Physical Security. And The Physical Vulnerable Factors of Network. Thereby this is expected to be utilized as a basis for the domestic Physical Security Technology development and deployment Road-map in a future.

본 연구의 목적은 최근 건설된 노인전용 조합주택으로 입주한 노인가구를 대상으로 거주자 측면에서의 주거환경 평가이며, 아울러 미국 조합주택에 대한 이해를 도모하고자 한다. 설문지를 통해 수집한 자료는 빈도와 백분율 회귀분석을 사용하여 분석하였으며, 총 171가구가 본 조사에 참여하였다. 조사대상 가구주의 평균 연령은 76세였으며 교육 수준은 높았고, 가족형태는 부부나 독남가구가 대다수였다. 조사에 참여한 가구들은 저렴한 주택비용, 안전성, 주택유지 및 관리의 용이성, 주거 내의 접근용이성을 현 주거환경의 선택 동기로 손꼽았다. 현 주거환경의 평가를 물리적 환경, 사회적 환경, 그리고 거주자 참여방식의 관리에 대한 만족도로 크게 3가지로 나뒀으며, 물리적 환경 관련 요소가 주거환경 평가와 관련한 만족도에 가장 중요하게 작용하였다. 본 연구결과는 장기적인 주택관련 비용의 저렴화와 노인의 독립성을 위한 지원성이 강화된 물리적인 환경의 구축이 무엇보다 주거환경 평가시 중요하므로, 향후 노인전용 대안주택 계획시 이점에 대해 고려되어야 할 것이다.

본 연구에서는 슈트용 직물의 촉각 자극 시 나타나는 감성 특성을 파악하고, 이를 바탕으로 직물의 스치는 소리가 공감각적 감성변화에 어떠한 영향을 미치는지를 분석하기 위해 물리적 평가 및 주관적 평가를 실시하였다. 피험자 20명을 대상으로 직물의 촉감을 평가하게 한 후, 그 직물의 스치는 소리를 제시하여 감각과 감성을 평가하도록 하였다. 복합자극으로는 직물별 tm치는 소리와 촉감을 동시에 제시하여 때 감성을 평가하였다. 실험결과 촉감에 대한 감성차원으로는 '심미성'과 '개성'의 두 가지 요인이 나타났고, 소리에 대한 감성차원으로는 '심미성'과 '고급감', '개성'의 세 가지 요인이 도출되었다. 심미성을 유발하는 촉각성 요인으로는 'pliable'과 'cool', 개성을 유발하는 촉감성 요인으로 'smooth'와 'cool'로 나타났다. 청각자극에 의한 감성은 'loudness'가 가장 큰 영향을 미쳤다. 촉감자극에 의한 직물 별 소리 자극을 부가하였을 경우 직물 소리의 물리량에 따라 심미성 요인에서 감성의 상승 및 하강 효과를 발견할 수 있었다.

The present study aims to investigates the effects of the physical sound clarity (D50, STI) on the subjective speech intelligibility of the both Korean and Chinese languages which can be caused by increase of the sound absorption in classroom. In order to this, sound measurements were undertaken at a classroom with and without absorption materials. Also, speech intelligibility tests were conducted by Korean and Chinese students using their native languages. As the results, it was found that both sound clarity and speech intelligibility were improved with increasing sound absorption. Also, it was revealed that Chinese speech intelligibility was more improved than Korean with same impose of sound absorption. It was considered by the difference of phonetic characteristics of two languages. Analysing correlation of physical sound clarity and subjective speech intelligibility, it was shown that D50 is highly correlated with Korean (0.696) and Chinese (0.707) respectively. Also, STI was highly correlated with Korean (0.651) and Chinese (0.665). Thus, it can be concluded that D50 and STI have significant correlations with the speech intelligibility.
