Objectives: This study aimed to survey the characteristics of air quality and meteorological conditions in a greenway park. Methods: We measured meteorological and health related factors, including noise, particulate matter ($PM_{10}$) and selected gaseous air pollutants at three locations in a greenway park and on a general roadside as comparison. The measurements were repeated four times from April to October 2014. Results: The average air temperature in the greenway park was $20.7^{\circ}C$ which was $1-2^{\circ}C$ lower than on the general roadside. The average $PM_{10}$ concentration in the greenway park was $85.0{\mu}g/m^3$, a level 2-3 times lower than that at the roadside. The noise level at the greenway site was 4.4 dB(A)- 23.0 dB(A) lower than at the roadside. The average CO, $CO_2$, $SO_2$ and NOx concentrations in the greenway park were lower than at the roadside. The average phytoncide and anions concentrations in the greenway park were higher than at the roadside. Conclusions: The urban forest of the greenway park may have some impact on air quality and meteorological conditions.

옥치율,박현석 부산교육대학교 과학교육연구소 1989 科學敎育硏究 Vol.14 No.-

The Nucleophilic substitution reaction of o, m-benzene-di-sulfonyl chlorides with various substituted anilines in methanol-acetonitrile binary solvent mixtures at -15℃ For the reactivity of substrates, m-benzene-di-sulfonyl chloride has higher than o-benzene-di-sulfonyl chloride according to the steric effect of ortho position and the order of magnitude for the second order rate constants, p-CH_3 aniline > aniline > p-Cl aniline is the tendency of nucleophilicity as expected. The magnitudes of ρ_N and β are lager than benzensulfonyl chloride and indicate a relatively advanced bond-formation in the transition state. Relatively small values of a/s is an indication that the polarity-polaribility(π^*) of solvent contributes more than the hydrogen bond donor acidity (α). The reaction proceeds via an associative S_N2 mechanism.

Afro-Americans의 춤 문화가 20C 미국 현대 무용에 미친 영향

박현옥 韓國舞踊敎育學會 2001 韓國舞踊敎育學會誌 Vol.12 No.1

The aim of this thesis is to analyse how the Afro-American dance and culture have inf1uenced on contemporary American dance in the 20th century. The writer tried to define the Irue dance of Americaness and over-viewed the social function and patters of Afro-Americans which have settled down in America by the comparison between the works of Ted Shawn and the thought of Alvin Ailey and Jose' Limo'n who have rooted in blackness and diverse ethnicity. The result of the analysis is as follows. 1.Contemporary American dance have been developed the expressive patters of American life in the spirit of puritanism and of pioneer on the premises of reasonable and practical aspect of functionalism by the explorers of Ted Shawn, Helen Ttmiris, Doris Humphry, and Marta Graham etc. But American dance and art have formed its unique style by the effort of dancers and artists who have pursuit universal and general concept of American culture by adding the jazz culture which have been regarded as the most American popular culture compared with WesteR Europe culture to traditional American art, and the jazz representing black culture over white culture have become an inevitable element of contemporary American art and dance, which forms Afro-American emotions that can not be excluded. 2.Afro-American darke have "Black" identity on the bases of modem sensitivity and traditional African motions differ from European dance though American dance have its stem from that of European Court Danre and Afro-American dance have beoome a mediator for the process of socialization or codirmation of African resistance in political identity and integrity of African cultlure over white society. 3.Afro-America dance is not predetermined form with improvisational jazz performance but is a dance of "chance and improvisation" which depend on individual characteristics of dancer with lively motion or step and dynamic movement of physical body using technical relationship with partner. These characteristics of Afro-American dance have been influence on the development of post modem dance since late 1960s. 4.Many Afro-America dancers who keep blackness and diverse ethnicity like Alvin Ailey and Jose' Limo'n opened new eyes on mascurinity. They have overcome the natural and intrinsic expressions of mascurinity of white race and developed diverse concept on macurinity by different sex, race, and ethnicity to male important element of American contemporary dance which have "universal language" among dynamic cultures. 5.The body in Afro-American dance expanded it meaning from "Natural body" to "Social body" suggesting theoretical background of feminism movement and others to be an epoch of development of dance in sociological research area.

Objectives : The authors recently found a suggestive evidence of linkage of chromosome 8p21-12 to schizophrenia in Korean multiplex families. Neuregutin 1 (NRGI) was identified in this locus as a positional and functional candidate gene for Schizo-phrenia, through several independent studies with European and Chinese populations. The purpose of this study is to determine whether NRGl is associated with schizophrenia in Korean population. Methods : Three SNPs (SNP8NRG221533, SNP8NRG241930, SNP8NRG243177) and two microsatellites markers (478B14-848,420M9-1395) located at the 5' end of NRGI were genotyped for 242 unrelated schizophrenia patients and the same num-ber of normal controls. Genetic association was tested by χ²-test (df=1). Not only for the whole patients group but also for asubgroup of patients with auditory hallucination. This subtype showed stronger linkage with chromosome 8p12 in the prior study of the authors with multiplex families. Results : G allele of SNP8NRG241930 was significantly in excess in the subgroup of patients with auditory hallucination compared to the control group (p=0.03, 0R=1.76). We also found that 3 SNPs haplotype TTC (p=0.04, 0R=0.58) and five markers haplotype TTC53 (p=0.01,0R=0.49) were associated with schziophrenia with a protective effect. Three SNPs haplotype CGT which is a part of the at-risk haplotype of the Icelandic schizophrenia families was found in excess in the patients group but no significant association was observed. Conclusion : NRGI might either play a mle in the predisposition to schizophrenia or be in linkage disequilibrium with a causal locus of this illness.

The couple force of the scapular stabilizers for upward rotation that include the upper and lower trapezius, serratus anterior muscles is essential to maintain the stability of shoulder joint. But if there is and imbalance of these muscles, it would occur many problems of shoulder joint. A push-up plus exercise with an unstable support is used in order to increase the muscle activity and stimulate the proprioception of shoulder joint. The purpose of this study was to compare the muscle activity of upper and lower trapezius, serratus anterior muscles and to determine which exercise is more effective when subjects perform push-up plus exercise in the stable support and unstable support. 15 healthy subjects perform push-up plus exercise in the stable support and unstable support. 15 healthy subjects and 15 painful subjects with injury of shoulder joint participated in this study. Surface electromyography data were collected during plus phase of push-up plus exercise. The types of push-up plus exercise were composed of three conditions. Stable type is subjects performed the push-up plus exercise on the fixed support and unstable type 1 is on the sling without shaking and unstable type 2 is on the sling with shaking by tester's manual. The upper and lower trapezius activities of injured group were higher than uninjured group at three measure conditions, but serratus anterior activities were not. The UT/SA ratio of injured group was higher than uninjured group at three measure conditions. The serratus anterior activities were most high at unstable 2 measure in both groups. The UT/SA ratio was most low at unstable 2 measure condition in injured group only. The present result revealed that push-up plus exercise in the unstable support with shaking which took most high serratus anterior activities and most low of UT/SA ratio is optimal cure method that can improve the imbalance of the scapular stabilizer.

입자충전상 여과장치에서의 집진효율 개선에 관한 연구

박옥현,손영수 釜山大學校生産技術硏究所 1997 生産技術硏究所論文集 Vol.52 No.-

이동식 입자충전층 여과장치의 효율을 개선하기 위해 향류, 병류 및 교차류에 대해 기류속도, 충전물 침강속도, 충전물 크기 및 분진부하 등의 조작조건을 각각 0.24∼0.47m/s, 2.98∼ 16.71g/s, 2∼6㎜ 및 3.5∼17.24㎎/s 범위에서 변화·조작 하면서 제진효율 측정실험을 수행하였다. 실험에 사용된 시료 분진은 1차 입자상 대기오염물질인 fly ash였고 그 입경범위는 1∼8㎛였으며, 입도분포는 대수정규분포였고, 기하평균경은 약 1.7㎛였다. GBF장치의 입구 및 출구에서 채취된 분진은 Coulter counter(Model TA Ⅱ and PCA Ⅰ)를 이용해서 크기별 개수농도로 측정되었으며, 효율계산시에 질량농도로 환산하였다. 본 연구를 통해 얻은 주요한 결론들은 다음과 같다; 모든 기류방향에서 기류속도가 증가함에 따라, 충전물 이동속도 감소에 따라, 그리고 충전물이 클 경우엔 분진부하가 감소함에 따라 각각 포집효율이 증가하는 경향을 보였다. 향류에서는 충전물 크기가 작을수록 제진효율이 증가하였으나 병류와 교차류에서는 그런 경향이 나타나지 않았다. 제진효율에 각 운전조건들이 미치는 영향은 복잡하기 때문에 이동식 GBF에서의 제진효율 평가를 위해 각 운전조건들을 독립변량으로 하는 중회귀식들을 만들었던 바, 이 식들을 적용해서 구한 효율 평가치들을 실측치들과 비교하므로서 특히 향류 및 교차류 때의 중회귀식들의 유용성이 확인되었다. In order to improve dust collection efficiency of moving granular bed filter (;MGBF) experiments measuring dust removal efficiency for countercurrent flow, concurrent flow and crosscurrent flow have been carried out under control of dust laden gas velocity, packing velocity, packing size and dust load in the range 0.24∼0.47m/s, 2.98∼16.71 g/s, 2∼6㎜ and 3.5∼17.24㎎/s, respectively. Fly ashes taken from a power plant whose equivalent diameter ranges from 1 to 8㎛ were selectively used as sample dust. Size distribution was log normal and geometric mean diameter was about 1.7㎛. Size of dusts taken at inlet and outlet of collector was measured by using Coulter counter(Model TAⅡ and PCA Ⅰ) according to each grade in number concentration, and the results were converted to mass concentration for efficiency calculation. Significant conclusions were drawn as follows ; For each flow type, collection efficiency tends to increase as dust laden gas velocity increases, as packing velocity decreases, and as dust load decreases when packing size is big. For countercurrent flow dust removal efficiency increased as packing size become smaller while such tendency did not happen for concurrent flow and crosscurrent flow. Since the effect of various operational conditions on dust removal efficiency is complex, multiple regression equations of efficiency were established using operation variables as independent ones. Particularly those regressions for countercurrent flow and crosscurrent flow appear to be useful.
