Design-build projects were devised to enhance the design technologies of the domestic construction industry and the efficiency of public works, contributing greatly to the development of construction technologies. However, as various stages of the process, such as formulation of basic plans and design documents, and deliberations proceed, claims, including changes in the requirements of clients, and design changes occur. These claims result in the delay in construction and an increase in construction costs. In this regard, this study attempted to identify main claims that delay construction and increase the costs of design-build projects, prevent claims in the future, and improve the efficiency of project implementation.

본 연구에서는 국내 실정에 맞는 한국형 CWS 구축의 일환으로 국내 배·급수 시스템에서 오염 사고 발생가능성이 있는 무기 오염물질 네 종류(카드뮴, 크롬, 망간, 납)를 선정하고 batch 실험을 통해 각 오염물질의 수돗물에 주입 시 감지 가능한 “최소 반응 농도(minimum response concentration)”를 결정하고자 하였다. 무기 오염물질 네 종류에 대해 수질 인자들의 최소 반응 농도를 추적한 결과 카드뮴(수질기준 0.005 mg/L)에 대한 최소 반응 농도는 0.05~0.08 mg/L, 크롬(수질기준 0.05 mg/L)에 대한 최소 반응 농도는 0.03 mg/L, 망간(수질기준 0.05 mg/L)에 대한 최소 반응 농도는 0.005 mg/L, 그리고 납(수질기준 0.01 mg/L)에 대한 최소 반응 농도는 0.02~0.08 mg/L인 것으로 분석되었다. In this study, four inorganic pollutants (cadmium, chromium, manganese, lead), that could cause contamination events in drinking water distribution system, were selected and batch tests were carried out to determine the “minimum response concentration (MRC)”, a part of Korean Contamination Warning system establishment. As the results, the minimum response concentration of cadmium was found to be 0.05 to 0.08 mg/L (0.005 mg/L : water quality standard) and that of chrome was 0.03 mg/L (0.05 mg/L). And the minimum reaction concentration was 0.005 mg/L for manganese (0.05 mg / L for water quality) and 0.02~0.08 mg/L for lead (0.01 mg/L).

Objectives:The purpose of this study was to evaluate the effect of social skills training (SST) for children in two different community settings, an elementary school and a child community center. Methods:Two separate groups of 15 children (10 boys and 5 girls) and 13 children (4 boys and 9 girls) participated in a SST program twice per week at an elementary school and a child community center, respectively. Age range of participants was from 8 to 10 years. Sixty-minute-long sessions of SST were continued twice per week for 4 weeks. Korean-Child Behavior Checklist (K-CBCL), Conner’s Rating Scales, Korean-Attention-Deficit Hyperactivity Disorder Rating Scale (K-ARS), Social Skills Rating System (SSRS), and Matson’s Evaluation of Social Skills with Youngsters (MESSY) were evaluated by their parents before and after the SST program. Results:Pre-and-post analysis of SST indicated no significant statistical differences in the elementary school group. However, the child community center group showed significantly increased scores for total social ability (p<.05) and decreased scores for attention problem (p<.05) on the K-CBCL. In addition, scores of MESSY were significantly increased (p<.05). These differences between the two groups were still significant after controlling pre-SST scores ; and difference of SST scores between the two groups disappeared after SST. Conclusion:Results suggest that SST in the community setting is an effective tool for prevention of social deficits and problems in attention by promoting social function and attention.

The purpose of this paper is to present a 2-D equivalent finite element model of a quadratic linear electromagnetic actuator that can save space and power without an energy conversion system. A 3-D finite element analysis for the design and analysis of a quadratic linear electromagnetic actuator requires a high performance computer for time-consuming computation. Therefore, we calculate the effective coil length for the equivalent 2-D finite element model, and demonstrate the accuracy of this model by compared with 3-D full model simulation

Objectives: Absorption is the mental state of operation in which a person in an activity is fully immersed in a feeling of energized focus, full involvement, and success in the process of the activity. For now, there are many studies to research in specific conditions and group of occupations. Through many studies, absorption has important meanings in general and clinical fields. It is worth to know persons who are doing well at absorption have what kind of personality. So, the present investigation sought to explore the relationship between absorption and personality dimensions. Methods: The relationship between absorption and personality dimension was investigated in a sample of 210 undergraduate students. Absorption was measured by the TAS(Tellegen Absorption Scale), personality characters was measured by the NEO-PI-R(NEO Personality Inventory Revised). We devided the students into two groups according to TAS[TAS≥16(N=95), TAS<16(N=115)]to evaluate differences in personality domains of NEO-PI-R. Chi-square test and t-test was used for differences in personality domains of NEO-PI-R and demographic variables according to variable. Pearson correlation test was used for relationship among the NEO-PI-R, TAS. We also used stepwise regression analysis to evaluate accountability of personality domains for absorption. Results: High TAS group had higher score of Neuroticism(t=3.319, p=.002), Extraversion(t=2.063, p=.040) and Openness(t=4.054, p=.000) domain than low TAS group. TAS was correlated with score of Neuroticism(r=.136, p<.05), Extraversion(r=.215, p<.01), Openness(r=.332, p<.01) in the total samples. In the stepwise regression analysis, TAS was explained partly by Openness and Neuroticism Conclusion: As hypothesized, The Neuroticism, Extraversion and Openness domain accounted for the great portion of variance in the absorption. Future study, It is necessary to explore in psychiatric patients for clinical application.

수심 제한을 고려한 수중 글라이더 경로 최적화

In this study, the problem of trajectory optimization for underwater gliders considering depth constraints is discussed. Typically, underwater gliders are controlled to dive and climb in a saw-tooth pattern at constant gliding angles. This approach is effective and close to optimal for deep water applications. However, the optimal path deviates from the saw-tooth path in shallow water conditions. This study focuses on finding more efficient gliding paths that can minimize the traverse time in the horizontal plane when the water depth is limited. The trajectory optimization problem is formulated into a minimum time control problem with inequality path constraints and hydrodynamic drag effects. A numerical approach based on the pseudo-spectral method is adopted as a solution approach, and the simulation results are presented.

The paper presents research for the established experiment environment of multi vehicle robot, localization algorithm that is based on vehicle control, and path tracking. The established experiment environment consists of ultrasonic positioning system, vehicle robot, server and wireless module. Ultrasonic positioning system measures positioning for using ultrasonic sensor and generates many errors because of the influence of environment such as a reflection of wall. For a solution of this fact, localization algorithm is proposed to determine a location using vehicle kinematics and selection of a reliable location data. And path tracking algorithm is proposed to apply localization algorithm and LOS, finally, that algorithms are verified via simulation and experimental.
