  • The purpose of the resent research is to investigate the characteristics of sound insulation at the circular voided concrete slab in the multi-housing. In order to do this research, the method for field measurement of floor impact sound level was used following the Korea Standard F2810-1996. For the multi-housing, three kinds of circular voided concrete slabs are used to measure the characteristics of sound insulation.The results are as follows; 1.The main factor affecting the characteristics of sound insulation at the circular voided concrete slab in the multi-housing is sound-absorbing materials in the circular tube. 2. The main factor to effect the difference of sound pressure level is circular tube in the concrete slab. 3. The forms of circular tubes effect the characteristics of sound insulation at the circular tube. 4. Sound Pressure Level resulting from the piping direction of circular tubes in little different to octave band level.More study will be needed about the depth and distance of sound insulation materials, and the components of sound insulation materials for the multi-housing.

  • A three-dimensional (3D) numerical analysis for the train-bridge interaction (TBI) system is actively developed in this study in order to investigate the vibration characteristics of rigid-frame reinforced concrete (RC) viaducts in both vertical and lateral directions respectively induced by running high-speed trains. An analytical model of the TBI system is established, in which the high-speed train is described by multi-DOFs vibration system and the rigid-frame RC viaduct is modeled with 3D beam elements. The simulated track irregularities are taken as system excitations. The numerical analytical algorithm is established based on the coupled vibration equations of the TBI system and verified through the detailed comparative study between the computation and testing. The vibration responses of the viaducts such as accelerations, displacements, reaction forces of pier bottoms as well as their amplitudes with train speeds are calculated in detail for both vertical and lateral directions, respectively. The frequency characteristics are further clarified through Fourier spectral analysis and 1/3 octave band spectral analysis. This study is intended to provide not only a simulation approach and evaluation tool for the train-induced vibrations upon the rigid-frame RC viaducts, but also instructive information on the vibration mitigation of the high-speed railway.

  • 본 연구에서는 위상배열 안테나의 기본방사소자로 사용될 선형 테이퍼형 슬롯 안테나를 설계 제작하여 그 특성을 실험적으로 고찰 한다. 테이퍼형 슬롯 안테나(TSA)는 박막, 경량, 간단한 제조와 고주파 단일 집적회로에 적합하다. 또한, 멀티 옥타브 대역폭, 적절한 높은 이득, 대칭적인 E-면과 H-면 방사패턴을 가진다. 마이크로스트핍 선형 테이퍼형 안테나의 급전회로는 마이크로스트립-슬롯 선로간의 트랜지션을 사용한다. 트랜지션은 두 면으로 이루어진다. 한쪽 면은 마이크로스트립 선로이고, 다른 한쪽은 슬롯 선로를 가지는 구조이다. 마이크로스트립 과 슬롯 선로의 길이는 마이크로스트립과 슬롯 선로의 교차면의 중앙에서 ${\lambda}_m/4$${\lambda}_s/4$이다. 넓은 대역폭을 얻기 위하여, 슬롯 선로의 종단부의 폭은 $1.75{\lambda}_o$로 하고, 큰 지향성을 얻기 위하여 슬롯 선로의 테이퍼된 길이는 $4{\lambda}_o$로 한다. 실험결과 마이크로스트립 선형 테이퍼형 슬롯 안테나는 5GHz의 중심 주파수에서 약 5GHz의 대역폭을 가지고, 대칭적인 E-면과 H-면 방사패턴을 가진다.

  • 1. Objectives and Methods A Study on the Characteristics of the Korean Adult Male Sound according to Sasang Constitution using PSSC with a Sentence. Sasang Constitutional Medicine(SCM) is the one of the traditional Korean Medicine. It classifies people into four categories like Taeyangin, Soyangin, Taeumin and Soeumin. The rule to classify is Appearance and Body Shape, Facial Appearance and Speech, Character and Talents and Diseases and Medications. This study was done to investigate the relationships between Voice and Sound parameters using PSSC(Phonetic System of Sasang Constitution) in a sentence. Experimental Participants were 195 Korean adult males including 1 Taeyangin, 37 Soyangin, 105 Taeumin and 52 Soeumin. Sasang Constitutional specialist used PSSC and Korean Medical Diagnosis to classify participants into four constitution. 2. Results In Pitch segment, Soyangin's Center freq.(4) was significantly high compared with Taeyangin and Taeumin groups. Soyangin's and Soeumin's Center freq.(6) was significantly high compared with Taeyangin and Taeumin groups. In APQ segment and Octave segment, there were no significant differences among four groups. In Shimmer segment, Taeumin's F Shimmer(1) and F Shimmer(2) were significantly high compared with Taeyangin and Soyangin groups. In Energy segment, Taeyangin's 2k-4k total sum, 2k-4k dev., C dev., C# dev. and D S.D. were significantly high compared with other groups. In Recording time segment, there was no significant difference among four groups. More Taeyangin cases and the other parameters are needed to determine constitution using PSSC and to make PSSC effective. 3. Conclusions From above result, there is the possibility of efficiency standard guide for constitution diagnosis by analyzation og voice.

  • 1. Objectives The purpose of this study lies on the objectification of the Sasang Constitutional diagnosis. This study was analyzing the constitutional characteristic of adult men voices by PSSC-2004. 2. Methods The study was conducted on the subjects inputted /a/ 2.5-3 sec of 231 adult men voices to PSSC-2004. The statistical analyses are applied to three groups: total group, under 55 year-old group, over 55 year-old group. The group of total 231 was composed with 5 Taeyangins, 32 Soyangins, 102 Taeumins and 92 Soeumins. The under 55 years old group was composed with 4 Taeyangins, 23 Soyangins, 83 Taeumins and 77 Soeumins. The over 55 year-old group was composed with 1 Taeyangin, 9 Soyangins, 19 Taeumins and 15 Soeumins. 3. Results 1) In total group, the Soeumin's mean value of center pitch(4)$(1,000{\sim}2,000Hz)$ was significantly high compared with the others (P=0.034). 2) In total group, the Soeumin's group 3 APQ was significantly low compared with the others (P=0.042). 3) In under 55 year-old group, the Soeumin's center value of center pitch 4$(1,000{\sim}2,000Hz)$ was significantly high compared with the others (P=0.025) 4) In over 55 year-old group, no statistical significance was found between the Taeyangin, Soyangin, Taeumin and Soeumin. 4. Conclusions In under 55 year-old group, Soeumin's voice showed high pitched sound (clearness) at the low frequency (1000-2000Hz). In over 55 year-old group, there is no significant differences. This fits in with that 'Soeumin's voice is 'Yu-tone' born by 'Shang-tone', very short and high.' 'Yu-tone' corresponds to 'Ra' and witch is highest among Gong, Shang, Gao, Chi and Yu. This is related with the appearance that the Soeumin's voice is weak, thin and high tone. Therefore it is supposed that Soeumin adult men's voices are thick, and there are vibrations of the ending. It is accepted one of the Soeumin's characters like as a mild tremor of limbs and deep breath caused by Soeumin's Qi-deficiency. This outcome accords with the theory that Soeumin's Qi is less than the Other constitutions.

  • 보청기와 같은 청력 보장구는 자가 이득 조절을 통한 미세 조절이 가능 할 수 있다. 0.25 kHz ~ 8 kHz 옥타브 주파수 밴드의 대상자 선호 이득 측정을 위해 두 종류의 자가 이득 처방 절차가 개발 되었다. 이들 절차는 일차원 사용자 조절 인터페이스(프로그램된 다이얼)를 이용하여 다차원 변수를 빠르게 획득 할 수 있도록 디자인 되었다. 두 종류의 자가 이득 처방 절차는 사용자 인터페이스가 6개 주파수 밴드의 이득을 동시에 조절 하는지(Procedure A) 혹은 각 주파수 밴드를 개별적으로 조절 하는지(Procedure B) 에 따라 구분 된다. Monte-Carlo 시뮬레이션은 두 종류의 자가 이득 처방 절차에서 첫 20번의 반복된 시도동안 가상의 실제 선호이득값에 빠르게 수렴 할 수 있음을 보여 줬다. 20명의 젊은 정상 청력인을 대상으로 두 종류의 자가이득 처방 절차에 대한 행동 데이터 평가가(실험-재실험에 관한 신뢰도) 이뤄졌다. 선호 이득 측정은 20 min 미만의 시간이 소요 되었다. 최소 일주일 이상 간격을 두고 측정된 두 번의 사용자 선호 이득의 평균 제곱근 편차는 대략 10 dB ~ 15 dB 수준이었다.

  • 울산 쇠부리소리는 1981년 8월 달천철장의 마지막 불매대장인 고(故) 최재만(1987년 별세)의 구술과 소리를 바탕으로 1980년대에 재연된 소리이다. 본 고는 1981년 영상 등 총 13종의 자료를 바탕으로 쇠부리소리를 음악적 측면에서 분석하고, 전승 과정에서의 변화 양상을 확인하는데 목적을 둔 논문이다. 도출된 결과를 정리하면 다음과 같다. 2017년 쇠부리소리 자료를 살펴본 결과, 풍물패는 상쇠, 부쇠, 징2, 북4, 장구4, 태평소1로 구성되어 있고, 장단은 질굿, 자진모리, 다드래기, 덧배기, 자진덧배기의 5종을 친다. 가창곡은 3소박 4박자의 덧배기 자진덧배기 장단에 맞추어, 또는 무장단으로 부른다. 구성음은 대부분 Mi-La-do의 3음 또는 Mi-La-do-re의 4음으로, 음역은 1옥타브를 넘지 않는다. 종지음은 모두 La로 동일하다. 1981년 발굴 이후 오늘날까지의 쇠부리소리 연행을 살펴본 결과, 크게 4가지의 변화를 발견할 수 있었다. 먼저 악곡의 구성이 '긴-자진'으로 분화되고, <금줄소리>, <애기 어르는 소리>, <성냥간 불매소리>가 첨가되었다. 둘째 가창 방식은 1980년대 재연 이후 '1인 선창자+다인 후창자'를 기본으로, 1인 후창자를 별도로 지정하기도 하였다. 더불어 2013년 연행된 <자진불매소리>는 <성냥간 불매소리>의 토대가 되었다. 셋째 <긴-자진 불매소리>의 선율적 변화가 관찰되었다. 박자구조는 모두 3소박 4박자이나, 속도가 느려지고, Mi-La-do의 3음을 골격으로 높은 re와 낮은 Sol이 첨삭되어 메나리토리의 특성이 명확히 드러난다. 마지막으로 풍물 악기는 꽹과리, 징, 장구, 북의 사물이 주로 쓰이며, 공연에 따라 소고, 태평소, 요령 등을 첨가하기도 한다. 장단은 자진모리, 다드래기, 덧배기, 자진덧배기 장단을 처음부터 연주했으며, 이후 질굿 장단이 추가되었다. 이와 같은 결과를 통하여 최초 발굴 당시, <애기 어르는 소리>와 같은 단순한 형태의 <불매소리>가 남성 노동요로 목적이 바뀌고 연희성이 강해지며 하나의 공연 예술로 변화되었음을 확인하였다.
