The purpose of this research is to identify new service opportunities for enhancing driving safety of intra-city buses based on driving behavior analysis. Service opportunity identification involves finding target customers of service (to whom), motivations for service (why), service contents (what), and service delivery process (when, where). This paper presents an analysis of driving behaviors using the operational data of intra-city buses in conjunction with traffic accident data and drivers' driving history data. This paper also presents four identified service opportunities based on the data analysis results. This research would contribute to enhancing driving safety of intra-city buses in Korea and serve as a basis for developing new services for driving safety enhancement.

Various types of cooperative relaying (CR) schemes exhibit different levels of throughput and outage performance because of their inherent trade-off between diversity gain and opportunity cost; in other words, the overhead that is associated with cooperation. This article attempts to answer whether cooperative communication is beneficial or not from the system-level viewpoint and furthermore, if it is, how its average throughput can be maximized while maintaining the target outage rate. In order to improve throughput at the required outage performance, we propose a unified selection criterion to deal with different levels of combining gain and opportunity cost associated with each scheme, which allows for the employment of different CR schemes for various positions of the mobile station. Our system-level simulation results for an IEEE 802.16j multi-hop relay confirm the varying levels of trade-offs among different CR schemes and furthermore, show that CR will be a useful means of maximizing the average throughput for a multi-hop relay system as long as each type of the cooperating scheme is carefully selected, depending on the position of the mobile stations.

This study analyzes the amendment history of Educare Law of Infants and Children, the Equal Employment Opportunity Law, and Employment Insurance Law, and also examines the present status of the employer-supported child care service through secondary analysis of other policy studies. The three laws concerning employer-supported child care can be said to hold in itself two main concepts: employers' obligations to provide child care, and government's financial support and administrative management. In terms of the first concept, laws have been amended to enlarge the number of enterprises legally-responsible for child care service and to relieve the financial burden from them. In terms of the second, laws have been amended to gradually extend the magnitude of government's financial support and to establish the systematic administrative management. Approximately a half of the policy target enterprises, however, is not complying the laws. In addition, employer-supported child care centers are only occupying less than 1% of the whole child care market. Thus, this study evaluates the current employer-supported child care service system and suggests several principles for its improvement.

레이더의 설계에 있어 레이더 성능 평가는 중요한 단계 중 하나이다. 그러나 조우 표적을 가지고 성능 시험을 수행하는 데는 시간 및 비용과 같은 제약점이 따르기 때문에 가상의 표적을 모의할 수 있는 장치가 개발되어 레이더 성능 평가에 사용된다. 가상의 표적 모의 장치는 광 지연 선로 및 DRFM(Digital RF Memory)을 이용하여 구현되어 왔으나, 모의 거리 및 사용 용도의 차이로 인한 시험 시나리오 구현 등에 있어 제약점을 가지고 있다. 이에 본 논문에서는 임의의 레이더 송신 신호에 대하여 정밀 거리 모의가 가능하며, 시험 시나리오 구현이 용이한 레이더 반사 신호 모의 장치 개발을 목표로 구현된 디지털 시간 지연 모듈에 대하여 기술하였다. 개발된 디지털 시간 지연 모듈은 펄스 인식 및 지연 간격 검출 방법을 적용하여 왜곡이 없는 시간 지연을 모의하다. 자체시험 결과를 통하여 성능 입증하였으며 그 결과에 대하여 기술한다.

This study was started with the objective of restoring abandoned embanked farms, which are recently increasing, to mud flat by putting in least amount of energy in the aspect of environmental restoration. For the direction and establishment of the proposal for the restoration of mud flat using embanked farms, a case of Maipo Wetland in Hongkong was analyzed, and a proposal was prepared considering the condition of mud flat in Gochang. The restoration of mud flat in Gochang is intended to create various wetland ecological spaces as well as to provide opportunities for experience, education, recreation, and tourism. Effort was made to development an environment closest to the local ecological environment considering the shape and topographical condition of existing abandoned farms. For construction of the habitat, a target species was chosen and the plan for selection, planting, and management of species of trees suitable for the target species was established. In addition, the water level will be controlled by water gates to conform to the resting, spawning, breeding, and migration period considering the behavioral pattern of waders, the target species. The research on the restoration of mud flat in Korea is in incipient stage and this study provided an opportunity to review the possibility of restoration of abandoned embanked farms to mud flat. For the success of mud flat restoration from a long-term perspective, development of acclimating design infrastructure, technology improvement for mud flat restoration, and basis of partnership for the maintenance should be prepared in a systematical way.

Programmed cell death (PCD) or apoptosis is a mechanism which is crucial for all multicellular organisms to control cell proliferation and maintain tissue homeostasis as well as eliminate harmful or unnecessary cells from an organism. Defects in the physiological mechanisms of apoptosis may contribute to different human diseases like cancer. Identification of the mechanisms of apoptosis and its effector proteins as well as the genes responsible for apoptosis has provided a new opportunity to discover and develop novel agents that can increase the sensitivity of cancer cells to undergo apoptosis or reset their apoptotic threshold. These novel targeted therapies include those targeting anti-apoptotic Bcl-2 family members, p53, the extrinsic pathway, FLICE-inhibitory protein (c-FLIP), inhibitor of apoptosis (IAP) proteins, and the caspases. In recent years a number of these novel agents have been assessed in preclinical and clinical trials. In this review, we introduce some of the key regulatory molecules that control the apoptotic pathways, extrinsic and intrinsic death receptors, discuss how defects in apoptotic pathways contribute to cancer, and list several agents being developed to target apoptosis.

To examine different types of influenza diagnostic test kits automatically, automated rapid influenza diagnostic test method based on image recognition is proposed in this paper. First, the proposed methods classify a variety of the rapid influenza diagnostic test kit based on support vector machine that analyzes the kits' feature point. Then, to improve the accuracy of test, the proposed methods match the histogram of both the target image of influenza kit and the input image of influenza kit for minimizing the effect of environment factors, such as lighting and exposure variations. And, to minimize the effect from composition of the hand-helds devices, the proposed methods extract the feature point and match point-by-point between target image of influenza kit and input image of influenza kit. Experimental results of 124 experimental group show that the proposed methods significantly have effectiveness, which shows 90% accuracy in moderate antigen, for the preliminary examination of influenza, and provides the opportunity for taking action against influenza.
