This study reviews the current status of Korean first graders, their experience with early care and education (ECE) programs, and their participation in private and after-school education. The research also examines how school adjustment during the first grade is related to family income, types of ECE programs, and participation in private and after-school education. Using the first year data of the Korean Child and Youth Panel Survey (KCYPS) 2010, this study analyzes 752 first graders who attended only one of two types of ECE programs (child care centers or kindergartens), after which two 25% income extremes were examined. The analysis demonstrates that children from low-income households attended child care centers more often, while children from high-income households attended kindergartens more often. For both low-income and high-income groups, child care centers had a lower starting age and longer attendance periods than did kindergartens. High-income household children started attending ECE programs earlier, experienced more private and after-school education, and received a larger number of private and after-school educational lessons. For the second research purpose, children from low-income families showed better peer relations in school adjustment, while children attending child care centers showed better teacher relations than children attending kindergartens. Children with after-school education also exhibited better peer relations. These findings show the importance of government support for early learning, especially for low-income families and offer a foundation for developing private education polices for early childhood before and after school entry.

Many ships in voyage experience weight and buoyancy distribution change by various reasons such as change of sea water density and waves, weather condition, and consumption of fuel, provisions, etc . The weight and buoyancy distribution change can bring the ships out of allowable trim, heeling angle. In these case, the ships should adjust trim and heeling angle by shifting of liquid cargo or ballasting, deballasting of ballast tanks for recovery of initial state or for a stable voyage. But, if the adjustment is performed incorrectly, ship's safety such as longitudinal strength, intact stability, propeller immersion, wide visibility, minimum forward draft cannot be secured correctly. So it is required that the adjustment of trim and heeling angle should be planned not by human operators but by optimization computer algorithm. To make an optimized plan to adjust trim and heeling angle guaranteeing the ship's safety and quickness of process, Uk! combined mechanical analysis and optimization algorithm. The candidate algorithms for the study were heuristic algorithm, meta-heuristic algorithm and uninformed searching algorithm. These are widely used in various kinds of optimization problems. Among them, heuristic algorithm $A^\ast$ was chosen for its optimality. The $A^\ast$ algorithm is then applied for the study. Three core elements of $A^\ast$ Algorithm consists of node, operator, evaluation function were modified and redefined. And we analyzed the $A^\ast$ algorithm by considering cooperation with loading instrument installed in most ships. Finally, the algorithm has been applied to tanker ship's various conditions such as Normal Ballast Condition, Homo Design Condition, Alternate Loading Condition, Also the test results are compared and discussed to confirm the efficiency and the usefulness of the methodology developed the system.

본 논문은 동적인 균형을 위한 새로운 동작변환 기법을 제시한다. 이는 불균형한 동작을 원래의 동작 특성을 최대한 보존하면서 균형잡힌 동작으로 고쳐주는 새로운 동작 편집 기법으로서, 정적 균형만을 다루었던 기존의 연구와는 달리, 동적인 동작의 균형잡기 문제를 해결한다. 이 알고리즘은 두발 로봇의 균형제어에 널리 쓰이는 개념인 zero moment point (ZMP)의 자취를 구한 후, 이를 분석하는 방법을 통해서 실현되며 구체적으로는 다음과 같은 네단계로 이루어진다. 먼저, 동작 데이타를 스플라인커브로 피팅한다. 그 다음 이 데이타를 사용하여 ZMP 자취를 계산하여, 동작중에 불균형이 되는 부분을 찾는다. 여기서, 불균형은 ZMP 자취가 지지영역 밖으로 벗어나는 구간으로 정의된다. 다음으로 벗어난 ZMP 자취를 지지영역 안으로 투영시켜 새로운 ZMP 자취를 구한다. 마지막으로 구해진 새로운 ZMP 자취에 부합하도록 원래의 동작을 수정한다. 이 과정은 원래의 동작을 최대한 보존할 수 있도록 constrained optimization problem으로 수식화된다. 우리는 실험을 통해 이 알고리즘이 kinematic한 방법으로 편집된 동작에 역학적 사실성을 보장하는 유용한 방법임을 입증한다.

최근 입체영상 콘텐츠를 소비하기 위한 인프라는 급속도로 구축되고 있지만, 이러한 수요를 충족시킬만한 입체영상 제작기반은 부족한 상황이다. 지금의 입체영상 제작환경에서는 기존에 평면영상을 제작하던 것과 같은 방법으로 입체영상을 제작하고 있다. 그로 인해 인간의 시지각과 카메라의 특성이 고려되지 않은 영상이 제작되고, 이것은 입체효과의 저하와 함께 영상 속 피사체의 크기가 현실과 다르게 왜곡되어 나타나는 등의 문제로 이어지고 있다. 본 논문에서는 이러한 문제를 인식하고 더 나은 입체영상 콘텐츠 제작을 위해, 입체영상 관람 시 나타나는 인간의 크기 지각 특성을 고려한 입체 카메라의 광축 간격 조절에 대하여 연구하였다. 우선, 카메라의 광축 간 거리에 따라 영상 속에 나타나는 피사체의 면적 변화와 비율 데이터를 산출하였고, 광축 간격을 변화시키며 실제 입체영상을 촬영, 관람자들을 대상으로 설문을 진행하였다. 그 결과 인간의 입체시는 인간의 두 눈간 거리인 6.5cm를 기준으로 약 60%에서 2,000% 범위인 3.9cm에서 130cm 내에서는 광축 간 거리가 변화하더라도 크기 지각에 왜곡을 느끼지 않는다. 그러므로 입체영상 촬영할 때 광축 간격을 3.9cm에서 130cm 내에서 유지한다면 영상 관람에도 크기 지각에 문제가 발생하지 않고 실제와 동일한 크기로 느껴지는 영상을 제작할 수 있을 것이다.

The purposes of this research were to find out general trends of employed women's stress and to investigate the differences and effects of related variables. The data were obtained through 239 employed women living in Kwangju and Chonnam. The major findings were as follows : 1) Employed women's scores of stressor, stress cognition and distress were under medium but coping scores were relatively high. 2) Significant differences in employed women's stressors were found according to age, income, job satisfaction, and family life cycle. Stress cognition differed according to job adjustment conditions and self-esteem. Also distress related with job conditions and object. Stress coping levels were different according to income, job conditions, self-esteem, and sex-role attitude. 3) In analyzing the causal effects among related variables, employed women's stressors were affected by job satisfaction and age. Also stress cognition were influenced by job satisfation and self-esteem. Job conditions showed significant effects on distress and self-esteem, sex-role attitudes showed on coping. Conclusively job satisfaction, self-esteem and gender equality were most important variables for employed women's stress. (Korean J of Human Ecology 2(1) : 25-37 1999)

It is important to provide the opportunity and means to change body posture frequently during the work period. Maintaining a given posture, even if it appears comfortable in the beginning, becomes stressful as time goes on. In order to design most products some knowledge of the dimensions of the human body is required. Data concerning human body dimensions are referred to as anthropometric data. Anthropometric data are used to establish many product dimensions such as the heights of work surfaces, minimum size for access openings, spacing between controls, mounting angles for displays, distance between user and controls, and so forth. The usual procedure is to design to accommodate 90% of the population of anticipated product users. In sosme instances it is necessary to provide a method for adjusting because it allows users to alter the produst's dimensions to meet their individual needs. When the user makes the proper adjustments, the product will be easier to use (e.g., the seat and rearview mirror adjustment mechanisms on automobiles) or more comfortable (e.g., office chairs and stereo headphones).

The intent of this study is to develop system dynamics model for assessment of organizational and human factors in nuclear power plant which can contribute to secure the nuclear safety. Previous studies are classified into two major approaches. One is engineering approach such as ergonomics and probability safety assessment(PSA). The other is social science approach such like sociology, organization theory and psychology. Both have contributed to find organization and human factors and to present guideline to lessen human error in NPP. But, since these methodologies assume that relationship among factors is independent they don't explain the interactions among factors or variables in NPP. To overcome these limits, we have developed system dynamics model which can show cause and effect among factors and quantify organizational and human factors. The model we developed is composed of 16 functions of job process in nuclear power, and shows interactions among various factors which affects employees' productivity and job quality. Handling variables such like degree of leadership, adjustment of number of employee, and workload in each department, users can simulate various situations in nuclear power plant in the organization side. Through simulation, user can get insight to improve safety in plants and to find managerial tools in the organization and human side. Analyzing pattern of variables, users can get knowledge of their organization structure, and understand stands of other departments or employees. Ultimately they can build learning organization to secure optimal safety in nuclear power plant.

Rapid industrial growth based on massive fossil fuel energy consumption has caused serious damages on natural environment and every aspects of human life. As demands for clean and pleasant living circumstance increases, conflicts and disputes around environmental problems have also been widespread. Given the 'environmental rights' is a relatively new legal concept, however, resolving environmental disputes through the traditional legal principles and litigation procedures could be restrictive and, in some sense. inefficient as well as expensive. With efforts to develop new legal principles on environmental disputes, the environmental dispute adjustment system has been introduced as an alternative dispute resolution to the traditional legal dispute procedures. The Korean Environmental Dispute Resolution Commission introduced as the environmental dispute adjustment system has been well established for the past twenty-seven years, given the steadily increasing numbers of applications to the Commission over environmental disputes. However, as most cases are still small in money terms and mainly subject to adjudication, the effectiveness and practical contribution of the Commission in the resolution of environmental disputes have in fact been limited. For the enhancement of the status and roles of the Commission as the prior instrument of the alternative dispute resolution(ADR) in environmental disputes, several suggestions could be considered as follows: First, mediation needs to be more activated than adjudication in order to meet the primary purpose of ADR that resolves environmental disputes according to free will of concerned parties. Second, the scope of mediation could be expanded to the areas including potential environmental damages. Third, the roles and responsibilities of the Environmental Dispute Resolution Commissions at both central and local levels need to be evenly distributed. Fourth, the mechanism and procedures of environmental dispute resolution should be standardized. Fifth, the status of the Environmental Dispute Resolution Commission could be elevated in rank by shifting its current affiliation from the Ministry of Environment to the Office of Prime Minister. Sixth, the organizational structure and human resources of the Commission need to be reinforced. Seventh, the current situation that tends to give priority to litigation procedures when an environment dispute is simultaneously pending in litigation and mediation should be eased and properly adjusted. Eighth, the adoption of mandatory mediation in advance to litigation needs to be discussed. Ninth, the legal authority of the Commission's decisions should be further guaranteed. If above suggestions are thoroughly reviewed and properly adopted, the roles, authority and power of the Environmental Dispute Resolution Commission would be increased in the era when environmental conflicts get widespread, requiring an effective alternative environmental dispute resolution mechanism.

Purpose: In the post-COVID-19, many consumers still feel uncomfortable with crowding in closed spaces. This study investigates how non-crowding affects consumer satisfaction and restaurant visit intention. Research design, data, and methodology: The data were collected from 350 people aged 20 and above. A total of 347 respondents, excluding 3 unfaithful respondents, were analyzed using Smart PLS 4.0 program. Result: Both spatial and human crowding have significant effects on satisfaction. On the other hand, neither spatial nor human crowding directly affected dine-out intention significantly. In addition, spatial crowding was found to have a direct and significant effect on in-store dining intention, but human crowding did not have a direct and significant effect on in-store dining intention. It was found that satisfaction had a significant effect on both dine-out intention and in-store dining intension. Conclusions: This study has expanded the range of consumer behavioral intentions by applying a non-crowded environment (S) to the SOR theory. Also, Consumer behavioral intention was expanded by dividing visit intention into a dine-out and in-store dining intention. Therefore, we propose measures to minimize human crowding by introducing a system such as adjustment of store operating hours, reservation system, store opening time alarm system, and reduction of cooking time.
