This study examines the traffic noise reduction effects of the diverse efficiency features of a sunken square, and investigates the reduction effects and characteristics of noise alterations according to the construction conditions in order to verify its possibility as a new noise reduction facility. The measured data were analyzed. As a result, (1) the traffic noise from the roads around the sunken squares exceeded the regulatory standards; (2) the sunken squares were protected from noise; (3) the sunken spaces yielded a greater reduction by 6∼7dB than the flat ground thanks to the diffraction effect; and (4) there were fine changes to noise according to the conditions of space construction. In short, a sunken square has the potential to afford new applications as a noise reduction facility in a highly concentrated downtown with the existing defects solved. In addition, its use for effective noise control is evident based on the noise characteristics of a space. Future studies need to include efforts to provide clearer quantitative data, as well as research on shape, layout, and materials.

We discussed the formative nature of a city square reffered to be the frame of creating environment in the this study. We raised a question that the place, the size and the form of a city square are out of harmony with a surrounding environmental condition, and examined the functional effect and the formate value of a sunken square at the same time. We got hold of the special shape and the specific character, the distinctive structure, and the influence of the minute temperature of a cuty aquare, and showed the improved direction how to make them better focusing on the target square of a cosmopolitan city of Seoul. Finally, to correct the above-mentioned problems, we emphasized the our traditional city square which is reffered to have a peculiar property, and proposed that a public institutuion should develope the city square, and should make an effort to reflect the design based on the scientific experiment.

In this work, we report the diagnostic relations among some primary pulse conditions such as the floating/sunken, deficient/forceful, large/fine, and the long/short pulses. For this purpose, we carried out a clinical test, in which 11 Oriental medical doctors had participated to diagnose the pulses for 1566 healthy subjects. The subjects were divided into 11 subgroups and each subgroup was allocated to an individual doctor. It resulted in that, for 847 subjects (54%), two or more than two pulse conditions were felt simultaneously, for which we counted the frequency of the pairs of the pulse conditions. For the statistical analysis, we used a Chi-square test. As a result, at high frequency, the forceful, large, and the long pulses were diagnosed in pairs or in their triplet, and a similar close relation was found between the deficient, fine, and the short pulses. The pairwise diagnoses of the pulse conditions between the forceful, large, and the long pulses, and between the deficient, fine, and the short pulses imply their close relatedness in clinics. This result is supported by the theory of deficiency/excess syndromes. Moreover, we show that the close relatedness among the pulse conditions can be understood in terms of the geometric features of the radial artery near the prominent bone. This is the first work which reports the relatedness between the primary pulses by an objective clinical test.

본 연구는 도심 내 주요 초미세먼지(PM_2.5) 발생원인 도로 인근에 조성된 도시공원을 대상으로 도시공원 내부 공간조성유형에 따라 PM_2.5의 농도변화를 분석하여 특성을 살펴보고자 하였다. 연구대상지는 부산시 진구 도심 내 12차선의 도로 중심부에 광장형 공원형태로 조성된 송상현광장으로 선정하였으며, 공원의 공간조성유형은 토지피복유형과 식생구조에 따라 도로변 광장(A), 선큰광장(B), 도로 경계부 다층식재지(C), 교목 하부(D), 잔디광장(E)으로 총 5가지로 구분하였다. PM_2.5는 초미세먼지 등급별 국가예보에 따라 좋음일, 보통일, 나쁨일 3일씩 총 9회 측정한 결과를 바탕으로 평균비교 분석을 수행하였다. PM_2.5 좋음일 기준으로 송상현광장 내 공간조성유형별 농도는 D, E < B, C < A 순으로 통계적 유의성이 있었다. PM_2.5 보통일과 나쁨일 기준은 D, E < A, B, C 순으로 유의하였다. 공간조성유형별 송상현광장 내 PM_2.5 농도 특성은 인근 차도로부터 확산되는 PM_2.5의 대기의 흐름의 영향이 큰 것으로 판단되었다. 차도와 15m 거리에 위치해 있는 A와 C의 경우 PM_2.5 농도가 높았으나, B는 도로로부터 40m 거리에 떨어져 있는 PM_2.5 농도가 높았다. 이는 B는 외벽구조로 둘러싸여 공간 내부의 공기순환이 느려 상대적으로 대기가 확산되지 못하는 것으로 판단되었다. D와 E의 경우 C의 공간조성유형을 통해 대기의 흐름이 차단된 후 공원 내부에서 대기의 흐름이 원활한 구조여서 PM_2.5 농도가 상대적으로 낮은 것으로 판단하였다.
