The purpose of this study was to investigate the effects of socio-demographic variables, family emotional environment and maternal discipline style on school children's emotional regulation. Subjects of this study consisted 953 elementary school students drawn from 4 elementary schools in Cheong-ju city and Cheongwon-gun. Data were analyzed by the methods frequency, percentage, Cronbach's ${\alpha}$, factor analysis, Pearson's correlation, and hierarchical regression using SPSSWIN 12.0 program. The results of this study were as follows: First, girls used greater problem-focused coping than boys did. Children in sixth grade used more problem-focused coping regulation compared to those in fourth grade. When children perceived higher level of family communication, emotional support, participation of family rituals, family worries, and parental conflict, they were more likely to use problem-focused coping. Additionally, both maternal supportive discipline and behavioral controlling discipline styles increased children's problem-focused coping. Second, girls presented greater emotional venting than boys did. Children in sixth grade expressed higher level of emotional venting compared to those in fourth grade. While family communication, family worries, and parental conflict increased children's emotional venting, family emotional support and participation of family rituals decreased it. Only mothers' psychological controlling discipline positively predicted children's emotional venting. Third, girls presented higher level of children's aggressive expression than boys did. The lower level of family support increased children's aggressive expression. Higher level of family worries and parental conflict increased it as well. Also, children's aggressive expression was positively predicted by mothers' psychological controlling discipline. Fourth, girls presented greater avoidance than boys did. Children in sixth grade expressed higher level of emotional avoidance compared to those in fourth grade. In family emotional environment, while family support lowered children's emotional avoidance, family worries and parental conflict increased it. Moreover, mothers' psychological and behavioral controlling discipline styles positively explained children's emotional avoidance. In conclusion, family emotional environment was the strongest factor to predict school children's emotional regulation among other variables.

This paper presents a production planning algorithm for minimizing the costs of production and subcontracting in SCM (supply chain management) environment. In our SCM environment, the several local plants that aye dispersed geographically produce parts and products. In this environment, we have to decide the production volumes of both parts and products considering the BOM (bill-of-material) structure to meet the fixed order quantity or forecasted demand quantity. Each plant produces the specified parts of product with finite production capacity. There exist subcontracting decisions relevant to the production capacity of each plant except the core process plant, and when we use the subcontractor's capacities we should be charged for the fixed subcontracting fees. The objective of this study is to solve the production planning problem, which minimizes the total costs of production, inventory, setup, and subcontracting under constraints of production and subcontracting capacity. For this problem, an integrated production planning model based on the multi-level capacitated lot sizing problem was formulated, and efficient decomposition algorithm was proposed. The experimental investigation shows that the proposed heuristic generates quite good solutions at very low computational costs.

The purposes of this study were to review the effects of textiles production on the environment, and to investigate the environmental consciousness and environmental preservation behavior of textile producers. This study was conducted by reference analysis and empirical research. To develope theoretical framework of dimensions of environmental behavior, references concerned were analyzed. And for empirical study, researcher developed a questionnaire based on the free writing by producers and references. The questionnaire included problems about environmental consciousness, environmental behavior, demographic variables, and environmental variables. 135 questionnaires were used for final data analysis. ANOVA and factor analysis were used. The results were as follows: First, the level of global environmental problem consciousness was relatively high. The conscious level of water pollution caused by the waste water from textile mills was the highest, and that of desertation of mountain caused by timber cutting was the lowest. The effects of textile dyers and finishers on the environment were the highest, and that of designers were the lowest. Second, the results of reference analysis showed that the dimensions of textile producers environmental behavior were resource and energy saving, solid waste reduction, and green product production. And the results of empirical study were resource and energy saving, resource reuse or recycling, solid waste reduction, and green product production, and total variances was 62.3%. The practice was the lowest. Third, global environment problem consciousness, environment problem consciousness caused by the textile life-cycle concerned, and clothing seperate-collection or not at residing place were effective on environmental behavior, and 52.45% of environmental behavior was explained with above variables.

With the commercialization and full-timeization of the livestock industry, civil complaints continue to increase, and the livestock industry is facing a crisis due to social problems such as odor caused by livestock manure, soil pollution, water pollution, and environmental pollution. In order to increase productivity in livestock farms, the amount of livestock manure generated is increasing due to excessive use of protein feed and high-density breeding environment, and complaints such as odor and water pollution due to management problems are increasing rapidly. Livestock odor has emerged as a serious social problem, and due to growing complaints, conflicts between the Ministry of Agriculture and Forestry and the Ministry of Environment are even causing the livestock industry to lower its status. There is an urgent need for solutions to identify problems in the livestock industry and improve policies. This study aims to develop a " Abelmoschus Manihot Jinhuakui " brand that can improve the intestinal environment of livestock, reduce odors caused by livestock excrement, and improve the productivity of livestock farms in order to improve the increasingly serious odor problem in livestock sites. For Jeju livestock farms, which place more importance on the environment by securing tourists, eco-friendly feed additives were applied to the experiment, the results were derived, and the focus was on solving fundamental problems of odor generation through the development and packaging of feed additive brands. We aim to fundamentally solve the odor problem of domestic livestock farms, secure eco-friendly livestock farms, and contribute to reducing livestock odors and increasing productivity through research results that reduce ammonia levels in each livestock farm.

Many researchers have modeled complicated problems with distributed AI technologies in distributed environment. Especially, intelligent agent technology we often proposed among researchers as efficient method to solve the complicated problems because agent technology makes possibile to share different problem solving abilities among processors in distributed processing environment. In this paper, we propose multiagent system model to solve distributed scheduling problem. At this point we apple CSP techniques to the multiagent model as individual problem solving ability of member agents. Scheduling problem is divided into subproblems according to constraints by distributed resources, then each agent solves its subproblem using CSP solver in the proposed model. This method improves scheduling efficiency. For meeting scheduling problem of case study, we show CSP modeling process and suggest problem solving procedure by multiagent system model.

In this paper, we propose a medium access control(MAC) protocol for reducing the energy efficiency and for improving the transmission efficiency in underwater acoustic sensor networks. In underwater environment, the transmission delay is longer and bandwidth is smaller than terrestrial environment. Considering these points, we propose a new MAC protocol to enhance throughput and to manage efficiently the energy of nodes. The proposed protocol operates as a channel reservation scheme to decrease data collisions, and uses a mechanism to control the hidden node problem and the exposed node problem occurred in ad hoc networks. The proposed protocol consists of the slotted based transmission frame and reduces data collisions between nodes by putting separately the reservation period in the transmission frame. In addition, it is able to solve the hidden node problem and the exposed node problem by reservation information between nodes. We carry out the simulation to evaluate the proposed protocol in terms of the average energy consumption, the ratio of collision, throughput, and the average transmission delay, and compare the proposed protocol to a traditional MAC protocol in the underwater environment. The simulation results show that the proposed protocol outperforms the traditional protocol under a various of network parameters.

The purpose of this study is to understand what kind of effects a local residents’ participation on a local environmental problem has on the Environmental consciousness of the resident, and on the local community. I (researcher) employed qualitative research methods on the residents' environmental movement, which claimed to preserve the Sung Mi Mountain from the Seoul City Hall's plan of the water reservoir construction. I tried to understand the participation motivation and participating actions, and also the changes and effects the participation brought at both a personal, and community level. The data were gathered by means of in-depth interview with the local residents and unstructured questionnaire. At first, through the residents' environmental movement, the participants acquired a growth in environmental consciousness. For example, they obtained better understanding of the environment, change of attitude to environment, and participation function. Secondly, it is meaningful that a local tie intervened by the environment, enforced self-governing, and shows how community sentiment plays an important role for local community organization. Moreover, the environmental movement contributed to developing a ‘culture for participation’. In conclusion, participating in a local environmental problem can be an integration of learning and practice and also leads to reflective thinking about the relationship not only between human beings and nature, but also among human beings. In addition, it can buildup a systemic cooperation for local problem-solving and the ability to make an alternative culture in the community. These are the significances of the local environmental problem-participation on the environmental education.

In this paper, We suggest new strategies on non-interactive agents applied in a prey pursuit problem of multi agent research. The structure of the prey pursuit problem by grid space(Four agent & one prey). That is allied agents captured over one prey. That problem has long been known in interactive, non-interactive of multi agent research. We trying hard to find its own solution from non-interactive agent method on not in the same original environment(circular environment). We used ACS applied Direction vector to learning and decide on a direction. Exchange of information between agents have been previously presented (an interactive agent) out of the way information exchange ratio (non-interactive agents), applied the new method. Can also solve the problem was to find a solution. This is quite distinct from the other existing multi agent studies, that doesn't apply interactive agents but independent agent to find a solution.
