Because of the increasing demand for day care centers, The Korean government has enforced childcare accreditation. The government has created the evaluation certification system for child care facilities. But the system includes variable items, and the physical rules are not sufficient for ensuring security and quality amenities. So this study, through literature search, examined the rules of Child Care Centers in the U.S. and compared them with those in Korea focusing on the provision of security and amenities. The standards found in 4 U.S. states were investigated, and the results are as follows. The rule pertaining to the size of indoor activity spaces in C.C.C. allows the spaces to be smaller in Korea than in the U.S. There is no specific criterion for infants and toddlers in our standard. When comparing the standards of Korea with those of the United States, Korea's standards do not state specific rules about child care facilities such as indoor furniture, finishes and space planning. Additionally, the binding force ensuring compliance with the standards of physical facilities is weak. Thus, the ratings of child care standards for the physical environment should be presented in detail. And if a center does not comply with the criteria, stronger penalties will have to be imposed.

This paper describes effectiveness of accident reduction on vehicles equipped with AEB using accident data occurring in Korea. During the statistical period, we used the number of vehicles which are covered by auto insurance and the number of accidents. To maximize the reduction effect of accidents caused by the driver's carelessness, the analysis was limited to Physical Damage Coverage that covers the cost of repairing or replacing the damaged vehicle caused by the driver's fault. Due to Personal Information Protection Law, it was not capable of comparing the same vehicle using Vehicle Identification Number in this study. Instead of that, we used it as a similar vehicle, so there are limits to the comparison and analysis results. As a result of this study, we have found that the effect of reducing accidents was different depending on the vehicle class, but it was generally concluded that the number of accidents decreased when the vehicle was equipped with an AEB system. Domestic research on the AEB effect of reducing accidents is not active yet. Therefore, it is absolutely essential to analyze the effects according to various conditions such as driver's age, occupation and gender as well as expanding the study models in the future.

This study presents the validation of a numerical model developed for dynamic analysis of buildings with roller seismic isolation bearings. Experimental methods allowed validation of the motion equations of a physical model of a building with and without roller bearings under base excitation. The results are presented in terms of modal parameters, frequency response functions (FRFs) and acceleration response. The agreement between numerical and experimental results proves the accuracy of the developed numerical model. Finally, the performance of the constructed seismic protection system is assessed through a parametric study.

본 연구는 한국 공보육 시스템의 근간이 되는 어린이집에서 최근 발생한 아동학대를 분석했다. 어린이집 아동학대를 이해하기 위한 첫걸음으로 본 연구는 어린이집 아동학대에 관한 가장 광범위하고 공신력있는 자료라고 할 수 있는 아동보호전문기관의 국가 아동학대 사례조사관리 시스템에 접근하여 2010년에서 2012년 사이 아동보호전문기관에 신고된 어린이집 아동학대 전수(n=462)를 연구 대상으로 삼았다. 자체 개발된 코딩 시스템을 통해 사례조사기록에서 아동학대의 구체적 특성 및 관련정보와 최종 조치 결과를 체계적으로 추출했다. 연구 결과 어린이집 아동학대의 낮은 학대 판정율과 낮은 신고 의무자에 의한 신고 비율, 높은 신체학대 비율(즉, 학대 유형별 동질성), 학대 심각성의 다양성이 나타났고 최종 조치 관련요인들이 피해아동, 학대 행위자, 어린이집 대상별로 서로 다르게 나타남을 알 수 있었다. 이를 바탕으로 아동학대 연구를 위한 학문적 함의와 어린이집 아동학대 근절과 예방을 위한 실천적 함의를 논하였다.

In recent years, smart clothing had been developed in order to better detect and monitor physical movement of the patient, so that such activities such as location identification and biometric recognition could be done. However, most of the sensing devices of smart clothing were limited to smart sensing sports clothing and the designs did not consider the physical characteristics and the behavior of the wearer. Therefore, this study aimed to create an open protection system by developing a wearable sensing device for health monitoring and location information. For this purpose, this study developed eleven types of wearable sensing design that could be commercially sold and worn by people who needed their biological information to be constantly monitored. The study conducted four tests in order to develop three types of sensing devices for various sensing wears. The purpose of this study was to expand the user rang of smart sensing wears, and provide a foundation for the development of distinctive wearable sensing devices reflecting the user. Furthermore, contribute to the design for the person subject to protection.

Multipurpose development of the coast and ocean can be considered as multifunction construction combining the functions of coastal protection, waterfront amenity and creation or rehabilitation of habitats. Multfunction development of coastal and ocean spaces can be accomplished by applying the ecosystem control structure of artificial habitats which will cultivate fishing ground with ecological harmony to the coastal protection system. To evaluate the applicability of ecosystem control structures as as fundamental coastal protection structure, wave control function of the structure is studied by numerical and physical analyses. Dimensional analysis and hydraulic experiment point out the importance of width and crest depth of ecosystem control structure, construction water depth and wave steepness. Wave control efficiency is estimated by the attenuation coefficient $(K_H)$ according to wave steepness $(H_0/L_0)$, relative constructed water depth $(h_i/H_0)$, relative berm width $(B/L_0)$ and relative crest depth $(h_B/H_0)$ of eosystem control structure. Empirical fomulas are suggested based on the results of model test by applying the multiple model based on this experimental results and numerical wave shoaling-dissipation-breaking model appears to be valid for the analysis of wave transformation around ecosystem control structure in the coastal waters.

In this paper, we focus on planing avoidance control for a supercavitating underwater vehicle based on the potential function method. The planing margin can be calculated using the relative position between the cavity center and vehicle center at the end of the vehicle. The planing margin was transformed into a limit variable such as the pitch angle and yaw angle limit. To prevent the vehicle attitude from exceeding the limit variable, a potential function based planing envelope protection method was proposed. The planing envelope protection system overrides commands from the tracking controller, and the vehicle attitude converges to a desired angle, in which the potential function is minimized. Numerical simulations were performed to analyze the physical feasibility and performance of the proposed method. The results showed that the proposed methods eliminated the planing, allowing the vehicle to follow tracking commands.

바이오인식은 각 개인의 신체적, 생리적, 행동적 특성을 자동화된 장치로 측정하여 이를 등록한 후, 개인을 식별하거나 인증하는 기술을 말한다. 그런데, 여기서 사용되는 바이오인식 정보는 개인을 식별할 수 있으므로 개인정보에 해당된다. 따라서, 이것이 유출되거나 오용되었을 때 정보주체의 프라이버시에 부정적인 영향을 미치게 된다. 본 논문에서는 바이오인식 정보와 관련된 국내의 법적 현황을 살펴보고 이와 관련된 침해현황을 살펴본다. 이어서 대표적인 바이오인식 응용 모델을 도출하고, 각각에 대한 취약점 및 대책 방안을 논의한다. 최종적으로 바이오인식 시스템의 개발자와 서비스제공자를 위해 바이오인식 정보의 보호를 위한 수칙을 제시한다.

High performance and reliability of the storage system to handle a very large amount of data has been become very important. Many techniques have been applied on the various application systems to establish very large capacity storage that satisfy the requirement of high I/O speed and physical or logical failure protection. We applied RAID and LVM to construct a storage system for the global data center which needs a very reliable large capacity storage system. The storage system is successfully established and equipped on the latest Linux application server.
