The indoor thermal conductivity test, unfrozen water test, and freezing pressure test were conducted on soil mixed with waste vinyl aggregate (PE aggregate). Consequently, lower thermal conductivity, less unfrozen water, and lower freezing pressure resulted from higher PE aggregate mixing ratios. Furthermore, the plate loading test and frost penetration depth test were conducted on field model road with a sub-base of PE aggregate and crushed stone. As a result, the bearing capacity of the road mixed with 10% PE aggregate exceeded the requirement, whereas frost penetration depth was reduced by 39% compared to that of using crushed stone only.

국가직무능력표준(National competency standards, NCS)은 산업현장에서 직무를 수행하기 위해 요구되는 지식, 기술, 태도 등의 내용을 국가가 체계화한 것이다. NCS기반 현장중심 교육과정을 적용한 방사선과 재학생 3학년을 대상으로 일반촬영에 대한 방사선사 직무수행도를 평가하였다. 평가 결과, 모든 촬영방식에서 우수 및 충족 비율이 93% 이상으로 현장중심 교육과정이 재학생의 직무수행도 향상에 긍정적인 영향을 끼친 것으로 판단된다. CR 방식은 전체적으로 가장 우수한 평가를 받았으나 대상자 간 편차가 크고 영상기기조작능력이 부족한 것으로 평가되었고 Film 방식은 노출조건 설정 및 현상작업이 문제점으로 평가되었다. DR 방식은 우수한 평가를 받았으나 영상기기조작능력, 부속기자재운영능력이 부족한 것으로 평가되었다. 각 촬영에서 성취수준 이하의 평가요소를 교과목 운영에 보완한다면 재학생의 학업성취도 향상뿐만 아니라 졸업 후 임상에서 방사선사 직무수행도 향상에 도움이 되리라 판단 한다.

In this paper, the material characteristics of field applied green slope soil for development of vegetation shotcrete using mineral additive are evaluated. From the results, after a consolidation of certain level is proceeded, soil hardness and soil strength are not affected by ages. However, in order to ensure slope stability, the cohesion should be improved of green slope soil.

There are bolt contraction torque decision standards in KSB 0101 for high tension bolt( torque calculation method) and in KSB 0140 for general bolts(bolt torque decision general rule), But in using bolt torque decision general rule method, friction coefficients between bolt and to-be-bolted object will rule the calculated yielding contraction axle force and yielding contraction torque, making it hard to determine the contraction torque in the field. So in other to determine the contraction torque for general bolts in field using high tension bolt torque decision method, the torque decision method for general bolt is proposed referencing high tension bolt torque decision method. And the field torque test is planned to verify the adaptability of the proposed method in the field.

The purpose of this study is to investigate the field application of Permeability recycled asphalt using Waste Asphalt Concrete and Resin. After the test construction, it was not cause problem, such as this stripping, falling and crack of pavement. Also, it was confirmed to be performance of equal or higher than of existing technology.

By amending of the special law on the safety management of the facility, coastal structures(breakwaters) has been incorporated into kinds of facilities. In this paper, a case study for condition assessment of coastal structures(breakwaters) is conducted according to the detailed guidelines established for coastal structures(breakwaters).

To verify the displacement estimation method which is based on the relation between displacement and strain, static and dynamic field test are performed on the real bridge structures. Static and dynamic displacements estimated by using strain signal are well agreed with measured one by LVDT. This study demonstrates that the displacement estimation method using strain signal can be effectively applied to the displacement measurement of bridge structures, which are crossing the river/road/railway or have high clearance.

Purpose: This study was to create and practically apply psychological skills training program(PSTP) for rhythmic gymnasts. Methods: Four rhythmic gymnasts aged ten to fifteen who are members of Korea Gymnastics Association and Office of Education in ‘G’ city were selected as research participants in 2014. They participated in PSTP for six months. Program effectiveness was examined through the questionnaire of CSAI-2, psychological skills, and self-management, list of competition result, and psychological counseling. The selected program was applied to each rhythmic gymnasts through supplementation sequence after practical skill training that reflected personal psychological skills level and characteristics. Results: Based on the data collected, nine specific psychological skills methods consisted of goal setting, breathing and relaxation, positive imagery, self-management, cognitive restructuring, self-confidence, performance routine, psychological counselling, and integrated performance routine were applied to the research participations. As they participated in PSTP, the following positive psychological effects were found to the research participant. First, participants’ competitive state anxiety was reduced. Second, participants’ psychological skills was improved. Third, participants’ self-management was enhanced. Fourth, participants’ performance was improved. Conclusion: PSTP was evaluated as an effective training program that helps rhythmic gymnasts’ psychological steadiness. Based on the result of the study, it is expected that more rhythmic gymnasts are trained using PSTP to improve their mental strongness, so that they perform their best athletic skills and talents in their competition.

Ninety ducks (one-day-old Pekins, 45 males and 45 females) were used to evaluate the effects of supplementing diets with Houttuynia cordata powder on the fatty acid profiles of duck breast meat. The ducks were allotted to one of the three treatment diets using a completely randomized design, each treatment-group containing three replicate pens with ten birds each (five of each gender). The experimental diets were: 1) Control (basal diet), 2) T1 (Control+ 1% Houttuynia cordata) and 3) T2 (Control+2% Houttuynia cordata). In spite of significant difference, the addition of Houttuynia cordata resulted in higher unsaturated fatty acid and lower saturated fatty acid contents than in the Control group. However, no remarkable difference was observed between 1% and 2 % Houttuynia cordata groups for fatty acid profiles.

After carrying out on-the-spot observation targeting each farmhouse of large-scale environment-friendly agricultural district (LEAD), Suncheon, Sancheong, Jangheung, Yeongam, Hamyang, Okcheon, and Jeongseon in 2015, only one LEAD, a farmhouse in Jangheung had used sustainable compost coming out under their own non-antibiotic livestock. The soil pH and EC at a depth of 0-20 cm in the seven LEADs were ranged between 5.3-6.6 and 0.4-1.2 dS m-1, respectively, with 0.03- 0.27% for T-N concentration, 22-322 mg kg-1 for P, and 0.05-0.29 mg kg-1, which were, in particular, low a farmhouse in Jeongseon. When intensively surveying on each farmhouse of Suncheon, Jangheung, and Okcheon for a growing period, seasonal soil pH was maintained above 6.0 and high in a farmhouse in Okcheon, with similar soil EC observed among the three LEADs. Seasonal soil T-N was 0.1% higher on the farmhouse in Suncheon than other two LEADs, with higher seasonal soil P observed on the farmhouse in Okcheon and higher soil K in the Jangheung. T-N concentration in rice (Oryza sativa L.) crops was the highest in Jangheung, and concentrations of T-N, P, and K decreased in a season. Plant height and number of tillers per hill were the highest on the farmhouse in Okcheon, where was similar or low plant diameter and SPAD levels compared to other two LEADs. Dry weight (DW) before harvest was ranged between 52-63 g, and DW, rough rice yield (kg), brown rice/rough rice (%), brown rice yield (kg), head rice (%), and broken rice (%) were not significantly different among the three LEADs. Total annual gross production ha-1 was the highest on the farmhouse in Okcheon (16,230,000 won) planting with high class of variety, ‘Milky queen’ atearly maturation, which was expected to be increased on an agricultural income. However, high amount of fertilizer was applied for growing the following crops on the farmhouse in Okcheon, affecting the highest balance of T-N, P, and K more than 200 kg ha-1.
