한국사회 학교폭력의 실태와 대처 방안에 關한 硏究

한진태 한국소년정책학회 2012 少年保護硏究 Vol.18 No.-

The word, "Young offender" is used in Korea indicating offenses committed by juveniles ranging in age from 10 to under 19. The range in age of juvenile varies according to time and nation, but these days "juvenile" as academic term indicates people whose age is ranged from 9 to 24. And the term, "delinquency" is used instead of offense. The juvenile delinquency is most severe problem of modern society globally. In recent, increasing of sexual assault, habitual criminal, decreasing age of delinquency and collectivization are remarkable phenomena of juvenile delinquency. Most of juvenile delinquency are originated from the impulse of the moment. With sudden change of society since 2000, severe delinquencies of juveniles are extended to new social issue. In this paper, protection methods from juvenile delinquency are proposed through surveying crime complex and diverse statistics based on the latest case and that recent juvenile delinquency is overall problem of family, school and society.

1g 진동대 실험을 이용한 연약 점성토 지반에서의 동적 p-y 곡선 연구

한진태,유민택,최정인,김명모 한국지반공학회 2010 한국지반공학회논문집 Vol.26 No.8

In this study, a series of 1 g shaking table tests were carried out for a single pile in soft clay with various input acceleration amplitudes and frequencies. Based on the results, dynamic p-y curves were drawn and, in turn, the dynamic p-y backbone curve was formed by connecting the peak points, corresponding to the maximum soil resistance, of the dynamic p-y curves. In order to represent the p-y backbone curve numerically, Matlock’s p-y formulations for clay was used to find the initial stiffness (kini) and the ultimate capacity (pu) of the clay, both of which are required to formulate the p-y backbone curve as a hyperbolic function. The suggested p-y backbone curve was verified through comparisons with currently available p-y curves as well as other researchers' centrifuge test results and numerical analysis results.

Evaluation of the Dynamic P-Y Curves of Soil-Pile System in Liquefiable Ground

한진태,김성렬,김명모 한국지반공학회 2007 한국지반공학회논문집 Vol.23 No.3

Various approaches have been developed for the dynamic response analysis of piles. In one of the approaches, the soil-pile interaction is approximated by using parallel nonlinear springs, namely the p-y curves. Currently available p-y curve recommendations are based on static and cyclic lateral load tests. Other researchers have attempted to extend the p-y curves by incorporating the effects of liquefaction on soil-pile interaction and derived scaling factors of p-y curves to account for the liquefaction. However, opinions on the scaling factors vary. In this study, the scaling factors, which reflect the variation of the elastic moduli of surrounding soils, were established combining the relationship between excess pore pressures and the natural frequencies of a soil-pile system obtained from 1g shaking table tests and the relationship between the elastic moduli of surrounding soils and the natural frequencies of a soil-pile system obtained from numerical analyses. As a result, the scaling factors were presented in an exponential function.

1g 진동대 실험을 이용한 액상화 지반에 근입된 말뚝에 작용하는 동적 토압 분석

In this study, the magnitude and phase variation of dynamic earth pressure acting on a pile in liquefiable soils were analyzed using a series of 1g shaking table tests. In the case of a pile in dry sand, the value of the dynamic earth pressure was the highest near the surface due to the inertia force of the upper load on the pile and it decreased as the depth of the pile got lower. On the other hand, for a pile in liquefiable sand, the magnitude and shape of the dynamic earth pressure were similar to those of the excess pore pressure and was largely affected by the deformation of soils. Furthermore, the inertia force of the upper load and the dynamic earth pressure acted in opposite directions in cases of dry sand and saturated sand where low excess pore pressure had developed. However, after liquefaction, those force components near surface acted unfavorably in the same direction. Finally, the Westergaard’s solution was modified and proposed as a method to evaluate the magnitude of dynamic earth pressure acting on a pile during liquefaction.

한진태,장영은 한국지반공학회 2016 한국지반공학회논문집 Vol.32 No.10

Waveform micropile is an advanced construction method that combined the concept of conventional micropile with jet grouting method. This new form of micropile was developed to improve frictional resistance, which consequently leads to achieving higher bearing capacity and cost efficiency. Two field tests were conducted to examine the field applicability as well as to verify the effects of bearing capacity enhancement. In particular, waveform micropile construction using jet grouting method was performed to evaluate the viability of waveform micropile installation. After testing, the surrounding ground was excavated to check the accomplishment on the shape of waveform micropile. The result showed that waveform micropile can be installed by adjusting the grouting time and pressure. In the loading tests, waveform micropile’s bearing capacity increased by 1.4 to 2.3 times depending on their shapes when compared with conventional micropile. Overall results clearly demonstrated that waveform micropile is an enhanced construction method that can improve bearing capacity.

조선시대 포도청의 기능과 역할에 관한 고찰

한진태,곽영걸 한국자치경찰학회 2013 자치경찰연구 Vol.6 No.1

조선시대의 포도청의 특징적인 기능은 다른 행정작용 또는 군사작용이 未分 化되어 있었다는 사실이다. 고려와 조선에 들어와 어느 정도 전문적인 경찰기 관이 등장하기는 하였으나 대체로 경찰은 다른 행정기능과 분리되어 있지 아니 하고 행정기관과 통합적으로 경찰기능을 수행하였다는 사실을 알 수 있다. 조선왕조실록에서 포도청이라 명칭을 처음 보이기 시작하는 때는 중종실록 39년 정월 경신조인 것이다. 뒤이어 명종실록 7년 정월 경무조, 명종실록 15년 8월 계축조에 포도청의 정식 명칭이 보이기 시작하고 있으며,임거정의 의적이 도성 내 외를 횡행하던 때를 계기로 포도청을 다시 확립된 것이다. 조선시대 포 도청은 이러한 기능을 유지하면서 조선사회의 기강을 바로잡고 나라의 치안 질 서에 기여하며 조선을 이끌어온 정부 기구로 1894년 갑오개혁까지 그 명맥을 유지할 수 있었던 것이었다.

Kinematic Analysis of Head and Trunk Movements of Young Adults while Climbing Stairs or a Ramp

한진태 대한물리치료학회 2010 대한물리치료학회지 Vol.22 No.6

Purpose: The purpose of this study was to investigate the kinematic adaptation of head and trunk to ascend stairs and a ramp. Subjects were healthy young adults. Three‐dimensional kinematic patterns of head and trunk movements were examined during stair climbing and steeper ramp climbing. Methods: Fourteen young subjects with no history of chronic or acute musculoskeletal, cardiovascular or respiratory disorders took part in this experiment. Kinematic data were collected using a 6 camera Vicon system (Oxford Metrix,Oxford, England). Repeated measures ANOVA analyses were used to investigate the effect of gait mode on kinematics of the head and trunk. Results: The angle of the trunk while ascending stairs or a ramp was modified in three human planes (p<0.05). The angle of head and neck during the ascending of stairs or a ramp was not changed in the sagittal plane but was changed in the frontal and transverse planes (p<0.05). Conclusion: This study describes and discusses some basic kinematic mechanisms underlying the pattern of head and trunk changes during stair and ramp climbing and showed that postural adaptation of the head and trunk is necessary to maintain balance.

발바닥굽힘근 근피로가 발목관절 고유수용성 감각을 감소시키는가?

한진태 대한고유수용성신경근촉진법학회 2019 PNF and Movement Vol.17 No.3

Purpose: This study investigated the effect of plantar-flexor muscle fatigue on the force sense and joint reposition sense of ankle joints in the healthy adults. Methods: Fifteen healthy subjects (male: 9, female: 6) participated in this study. A digital dynamometer was used to measure the force sense error while a wireless motion capture device was used to measure the joint reposition sense error. To induce plantar-flexor muscle fatigue for a dominant lower extremity, the subjects were asked to perform plantar flexion until exhaustion while barefoot. The differences in force sense error and joint reposition sense error for the ankle joint were measured immediately. The Wilcoxon test was used to compare these values before and after inducing plantar-flexor muscle fatigue. Results: The force sense error and joint reposition sense error of ankle joints after inducing plantar-flexor muscle fatigue increased significantly compared to the values before inducing muscle fatigue. Conclusion: This study suggests that plantar-flexor muscle fatigue could degrade the force sense and joint reposition sense in ankle joints. In addition, it could deteriorate ankle proprioception.
