The current study examined the ability to predict Gottman's four dysfunctional communication behaviors during marital arguments based on the level of surface and core problems in marriage. Core problems were composed of three factors: caring, power, and commitment problems. A self-report questionnaire was administered to 182 married women residing in Busan. The results of multiple regression analyses revealed that a woman's degree of criticism was predicted by surface and caring problems when controlling for the other variables. The degree of contempt was predicted by a commitment problem as well as surface and caring problems. Defensiveness was determined only by a commitment problem, while stonewalling was determined only by a power problem. Overall, these results showed the importance of core problems in understanding the causes of the four dysfunctional communication behaviors - especially contempt - and suggested that additional attention should be given to a commitment problem as a contributor to the expression of contempt and defensiveness.

As the technology of rice production in Korea has rapidly developed and progressed over the last few years, many problems in rice production have been solved. But with the introduction of new genetic material, the increased use of pesticides, higher fertilizer rates and closer plantings, new problems are beginning to emerge. The brown plant hopper outbreak in 1975 resulted to a great extent from some of the changes in management practices. Some rice diseases and nutritional problems that have existed in Korea but have not been considered of serious consequence, are now becoming increasingly severe and possibly as limiting as the hopper outbreak in 1975. Other diseases and nutritional problems are completely new and their cause and significance have not yet been adequately defined. In this discussion there is no Intention to state, nor is there evidence to support a statement, that any of these problems are going to be limiting factors in the future production of rice on the Korean peninsula. Rather this is an attempt to bring together some of the current field problems in Korean rice so that they can be discussed and where necessary receive suitable consideration for research and control.

This study analyzes the theoretical background concerning problem solving, mathematization and real-life problems. Further it examines how middle school mathematics teachers and high school students of first grade recognize the real-life problems provides in textbooks concerning the area of geometry. Following those results found from this analysis, this paper reveals the issues and problems that we noticed through the analysis of real-life problems from textbooks, level 8 and level 9, Also we suggest the application of them along with the development of real-life problems for students' uplifting problem solving skills.

In this paper, descriptive assessment method for middle school mathematics was evaluated by developing a framework for designing and grading problems for descriptive assessment and analyzing the effectiveness of the problems. The new descriptive assessment problems were developed by reviewing the current 7th National Mathematics Curriculum of Korea and aligned mathematics textbooks to define a set of problem design principles and evaluation framework for the assessment strategy. The developed problems were first pilot tested and then revised based on the feedback from the test. The final version was field tested by 100 students in 7th grade middle school. After the field test, the problems were graded by two middle school math teachers and one math education researcher to determine the overall correlation between graders and also to analyze effectiveness of the evaluation framework of the test. This result of this study is expected to assist in the further development of descriptive problems and grading framework by providing a reference work for teachers to better understand the process and the limitations of executing the new assessment strategy.

Household chaos, represented by high levels of disorganization and instability in the home, has been linked with suboptimal outcomes for preschoolers. The aim of this study was to examine the roles that sleep problems and executive function play in the association between household chaos and preschoolers' aggression and prosocial behavior. The sample for the study consisted of 420 preschoolers and their mothers. The mothers provided reports on the level of chaos in the home and their preschoolers' sleep problems, executive function, and social behavior, including aggression and prosocial behavior. The data was analyzed using structural equation modeling. When preschoolers' sleep problems and executive function were included in the model as mediators, the results indicated that household chaos did not have direct effects on preschoolers' aggression and prosocial behavior. Such effects were instead serially mediated by preschoolers' sleep problems and executive function, respectively. The higher the degree of household chaos, the more preschoolers displayed sleep problems and deficits in executive function, resulting in more aggression and less prosocial behavior. The findings from this study emphasize the significance of reducing household chaos in order to reduce preschoolers' aggression and promote prosocial behavior. They also underscore the need to identify additional variables that mediate the impact of household chaos on preschoolers' social outcomes.

Korean agricultural extension services faces a challange due to decentralization. In order to develop agricultural extension services the various aspects must be considered. Especially extension program planning in based on needs, concerns and problems of extension service's clientele. Program development keep in tune with local needs and problems. Programs should be based on a thorough analysis of facts relevant to a given situation.

This study grasped problems and properties of rural tourism through Cooperative Tourism Development Model Project, so it provided to develop network program and to indicate long-term development direction. This study area was Gubyung-Areum village in Boeun-gun, Chungcheongbuk-do. This village has superior natural landscape and rich area theme. Also, this village was chosen in Areum Village Revitalization Project in 2002, infrastructure full equipment was achieved. Gubyung-Areum village is administering buckwheat flower festival and experience program by Bo-Eun County Office help to change the farm stay village to the rural experience village. But, there were some problems to operate in experience program. So that Chungcheongbuk-do Provincial Government Republic of Korea is propelling Cooperative Tourism Development Model Project for coping these problems from 2007.12.31 to 2008.9.30. This study is going to develop tourism network program that take advantage of enough area resources grasping problem of Gubyung-Areum village through propulsion of Cooperative Tourism Development Model Project. This study present Developing Strategies for Gubyung-Areum village through investigation, analysis and operation process.

Purpose: The study was done to investigate behavioral problems in toddlers who were born prematurely and to analyze related factors. Methods: A cross-sectional explorative study was conducted with 72 preterm birth (PTB) children at 24 to 41 months of corrected age who were born at 28 to 37 weeks' gestation. During home visits, behavior problems were assessed using the Behavior Rating Index for Children (BRIC). Using a BRIC score of ${\geq}30$, children with suspected behavior problems were grouped in the non-regular behavior group. Results: Of the children, 38.9% belong to the non-regular behavior group. The mental development index score for the Korean-Bayley Scale of Infant Development- II was higher for the non-regular behavior group compared to the regular behavior group (t=2.26, p=.027). Logistic regression analysis showed that lower maternal attachment (<96, OR=3.4, 95% CI[1.1, 10.4]) and higher parenting stress (${\geq}97$, OR=4.8, 95% CI[1.3, 17.3]) were independently related to non-regular behavior. Conclusion: PTB Toddlers are at risk for behavior problems which are associated with low cognitive performance. Maternal-child attachment and maternal parenting stress were strongly related to behavior problems in these children. More attention is needed to understand possible behavior problems in young children with PTB, particularly focusing on maternal-child interaction and maternal mental well-being.
