In recent years, ESG investment is increasing worldwide, and awareness of ESG risks such as environment, society, and governance is increasing, and non-financial investments are considered when making investment decisions. With the recent Corvid 19 crisis, the focus is on the environment, and investments related to bio and health are gaining popularity, while new investments are completely suspended in coal-related businesses, and decisions are made in the direction of sequential termination or withdrawal of existing businesses This has resulted in an increasing number of managers setting climate change and sustainability as top priorities in their investment portfolios. As a result, it is necessary to present effective countermeasures to changes in the investment environment, and to make efforts to respond and prepare an investment system that can help build a risk management system. Therefore, I would like to briefly review the ESG investment trends and present implications considering shared growth and mutual benefit.

In grid system, Task scheduling based on list scheduling models has showed low complexity and high efficiency in fully connected processor set environment. However, earlier schemes did not consider sufficiently the communication cost among tasks and the composition process of lightpath for communication in optical gird environment. In this thesis, we propose LSOG (Leveling Selection in Optical Grid) which sets task priority after forming a hierarchical directed acyclic graph (DAG) that is optimized in optical grid environment. To determine priorities of task assignment in the same level, proposed algorithm executes the task with biggest communication cost between itself and its predecessor. Then, it considers the shortest route for communication between tasks. This process improves communication cost in scheduling process through optimizing link resource usage in optical grid environment. We compared LSOG algorithm with conventional ELSA (Extended List Scheduling Algorithm) and SCP (Scheduled Critical Path) algorithm. We could see the enhancement in overall scheduling performance through increment in CCR value and smoothing network environment.

This study is intended to present effective career guidance and direction by identifying the various factors involved in the career preparation behavior for the improvement of the employment rate of culinary and foodservice management major field students. This study was established on the hypothesis of a structural relationship that career decision-making self-efficacy develops career maturity and career preparation behavior on the basis of social cognitive career theory, which was verified through empirical analysis. Out of 450 survey responses from by Culinary and Foodservice Management Major Students, a total of 302 questionnaires were used for the final analysis due to missing values and biased responses(response rate: 83.6%). Collected data were identified using SPSS 16.0 and AMOS 5.0. A higher-order factor model was employed (High-order model) before a confirmatory factor analysis, and this study examined its reliability and validity analysis for hypothesis testing. Career decision-making self-efficacy had positive effects on career maturity(t=6.86, p<0.001) and career preparation behavior(t=3.83, p<0.001), and career maturity had positive effects on career preparation behavior (t=2.79, p<0.01). As a result, all hypotheses were accepted. These results confirmed that strengthening students' faith in themselves with competencies is core competencies with career-related issue can be the driving force that can enable students to develop into mature professionals. Therefore, this study suggests an awareness of the importance of career decision-making self efficacy and proposes a need for a systematic and integrated career counseling program that can improve it.

생산자 중심에서 소비자 중심으로의 경영 패러다임이 변화함에 따라, 이제 디자인 경영(design management)의 시대가 도래하였다 즉, 제반 기능의 활동이 독립적이고 순차적으로 이루어지는 기존 경영방식(즉, 제품 개발 $\rightarrow$ 제품 디자인 $\rightarrow$ 제조 $\rightarrow$ 마케팅 $\rightarrow$ 판매)과는 달리, 디자인 경영은 디자인을 중심으로 제반 기능간의 통합과 조정을 이룬다. 이 결과, 디자인 경영은 조직간의 커뮤니케이션을 활성화시키며 소비자의 추상적인 욕구가 구체적으로 상품에 표현되도록 노력한다. 이렇게 함으로써, 디자인 경영은 기업 이미지 창조의 역할을 적극적으로 수행하는 것이다. 이와 같은 소비자 중심의 경영은 과거 제품의 판매(sales)지향적이던 기업 활동을 소비자와의 관계(relationship)지향적으로 변화시키고 있다. 본 연구의 분석 목적은 제품 디자인을 품질경쟁력의 결정요인으로서 포함시켜 품질경쟁력의 평가모형을 개발하고 품질경쟁력의 결정요인 및 상관관계와 품질함수를 추정함으로써 제품 디자인 및 디자인 경영의 기능적 역할을 규명하고 디자인 경쟁력 수준을 평가 및 측정할 수 있는 모형을 정립함과 동시에 이를 제고할 수 있는 정책방향을 제시하는 것이다. 이로써, 본 연구는 신상품의 개발과정에서 어떻게 제품 디자인이 연구개발, 제조, 마아케팅, 판매 등의 제반 기능들과 상호 작용하며 이들 기능들의 통합과 조정을 추구할 수 있는가를 보여주는 디자인 경영의 이론적 기초를 제공하고자 함이다. 상기와 같은 연구목적과 분석목표를 위하여, 한국 제조업 부문의 400개 표본기업에 대하여 소정의 설문조사를 통하여 추출된 측정변수들을 기초로 품질경쟁력의 결정요인을 분석하고 품질경쟁력 지수를 도출하여 산업부문별 및 제품유형별로 비교하였으며, 품질함수를 추정하였다. 전술한 분석결과를 토대로, 디자인 경영이론의 기초를 제공하기 위한 시도로서 제품 디자인의 파급효과와 인과관계에 대한 가설검정을 실시하였다. 본 연구의 분석 결과는 다음과 같이 요약될 수 있다. (1) 품질경쟁력의 결정요인으로서 주요 제품들의 기능성, 기본 성능, 제품성과의 기술적 성취도, 제품 수명(내구성), 신뢰성, 핵심 기술력, 사용 편의성, 서비스 편의성, 생산 용이성, 제품 디자인의 우수한 정도가 a=0.01 수준 하에서 유의적으로 추정되었다. 이들 변수들 중에서 품질경쟁력에 가장 큰 영향을 미치는 측정변수는 제품의 기본 성능, 수명(내구성), 신뢰성, 제품 디자인의 순서로 추정되었다. 이것은 한국 제조업이 아직 산업 디자인이 품질경쟁력에 크게 영향을 미치는 성숙단계에 이르지 못하였음을 의미한다. (2) 제품 디자인에게 영향을 끼치는 유의적인 변수는 연구개발력, 연구개발투자 수준, 혁신활동 수준(5S, TPM, 6Sigma 운동, QC 등)이며, 제품 디자인은 우선 품질경쟁력을 높여 간접적으로 고객만족과 고객 충성을 유발하는 것으로 추정되었다. 상기의 분석결과로부터, 본 연구는 다음과 같은 정책적 함의를 도출하였다. 첫째, 신상품 개발과 혁신을 위한 포괄적인 연구개발 프로젝트를 품질 경쟁력의 주요 결정요인(제품의 기본성능, 신뢰성, 수명(내구성) 및 제품 디자인)과 연계하여 추진해야 할 것이다. 둘째, 기업은 디자인 경영 마인드 제고와 디자인 전문인력 양성을, 대학은 디자인 현장 업무를 통하여 창의력 증진과 기획 및 마케팅 능력 교육을, 정부는 디자인 기술개발 및 디자인 교육지원의 강화를 통하여 각각 디자인 경쟁력$\rightarrow$품질경쟁력을 제고시켜야 할 것이다.

In this paper, we propose a method to recognize the action direction of human by developing 4D space-time (4D-ST, [x,y,z,t]) features. For this, we propose 4D space-time interest points (4D-STIPs, [x,y,z,t]) which are extracted using 3D space (3D-S, [x,y,z]) volumes reconstructed from images of a finite number of different views. Since the proposed features are constructed using volumetric information, the features for arbitrary 2D space (2D-S, [x,y]) viewpoint can be generated by projecting the 3D-S volumes and 4D-STIPs on corresponding image planes in training step. We can recognize the directions of actors in the test video since our training sets, which are projections of 3D-S volumes and 4D-STIPs to various image planes, contain the direction information. The process for recognizing action direction is divided into two steps, firstly we recognize the class of actions and then recognize the action direction using direction information. For the action and direction of action recognition, with the projected 3D-S volumes and 4D-STIPs we construct motion history images (MHIs) and non-motion history images (NMHIs) which encode the moving and non-moving parts of an action respectively. For the action recognition, features are trained by support vector data description (SVDD) according to the action class and recognized by support vector domain density description (SVDDD). For the action direction recognition after recognizing actions, each actions are trained using SVDD according to the direction class and then recognized by SVDDD. In experiments, we train the models using 3D-S volumes from INRIA Xmas Motion Acquisition Sequences (IXMAS) dataset and recognize action direction by constructing a new SNU dataset made for evaluating the action direction recognition.

This study examines the roles of government and reasons of defeat on 9.11 terror, iraq war between 2001 and 2003. The administration functions critical role of national security. And punctual, accurate information supply capability helps policymaker's decision-making. Hence, information of punctuality and accuracy should be given to policymakers. And without two above written factors, it will result in failing. Information concoction on policymaker's pressure, biased informant, inaccurate information and lack of assembly means under the extensive organization and technologized spying means, Fail to keep information objectivity, leads to information failure. In the context of a series of facts, we shall cover the position of government and reasons of calamities. Two incidents deem as information failure by national security service, but concoction of Iraqi mass destruction weaponry is believed as bush administration's deception on account of political gains. For fully functional government role, governing body should reinforce all aspects of gathering, analyzing, and making use of information more objectively in the first place. In particular, information concoction involving policymakers post massive stumbling block to organized outcome. The thesis presents a prospective view of government position under the U.S. secret agent over 9.11 terror and Iraq war.

In Korea, annual precipitation and its variability have gradually increased since modern meteorological observations began, and the risk of disasters has also been increasing due to significant regional variations and recent abnormal climate conditions. Given that damage from storms and floods mainly occurs around rivers, it is crucial to determine the appropriate design frequency for river-related projects. This study examined existing design practices used to determine hydrological design frequencies and suggested a new method to determine appropriate design frequencies. The study collected available data pertaining to seven evaluation factors, specifically the basin areas, shape parameters, channel slopes, stream orders, backwater effect reaches, extreme rainfall frequencies, and urbanized flood inundation areasfor 413 local rivers in Chungcheongnam-do in Korea. The estimated weights for areas of extreme rainfall frequencies and urbanized flood inundation were found to be 18, having a great effect on determining the design frequency. Compared with the established design frequency in previous government reports, the estimated design frequency increased for 255 rivers and decreased for 158 rivers.

Unsignalized intersections are classified into two-way-stop-controlled(TWSC) and all-way-stop-controlled(AWSC) intersections for the analysis of capacity and level of service. There is no AWSC intersection in Korea, but non-controlled intersections are common. Non-controlled intersections are operated only by the driver's decision without any control. However, the study for the analysis of capacity and level of service of the non-controlled intersection has been rare. As the first stage research, this study aims to determine the measure-of-effectiveness (MOE) for the performance evaluation of non-controlled intersections. The relationships between traffic volume and the intersection passing time (delay) and number of conflicts on each intersection are analyzed. It was found that the number of conflicts were more sensitive to the traffic volume compared with the delay. It means that number of conflicts can be the MOE for the performance of non-controlled intersection. The analysis of the number of conflicts and traffic volume showed a linear relationship, so that traffic volume can also be an MOE. The level of service of non-controlled intersection can be determined with either of the MOE's. Since the performance is also influenced by the ratio of traffic volumes of crossing streets, the traffic volume should be adjusted by the ratio. The capacity of non-controlled intersection was suggested to be 2,000veh/hr referring that of AWSC intersection in the USHCM. The criteria was suggested by evenly dividing the traffic volumes based on the capacity.
