Purpose: The purpose of this study is to identified patterns and trend of studies and to analyzed the nursing research related to the mother-child interaction in Korea and to improve direction of nursing research in mother-child interaction in Korea. Method: The research studies related to the mother-child interaction were selected from the Korean Nurses Academic Society Journal, and from dissertation, which were conducted between 1961 and 2002 with the consideration of the condition and the cultural specialty of Korea. The total numbers of the studies were 34. These studies were classified according to 1)time of publication or presentation, 2)research design, 3)type of interaction objects, 4)measurement tool, and 5)chief content of studies. Ressult: 1) Until 1984, there was no research studies related to mother-child interaction. The number of studies on the mother-child interaction on the mother-child interaction has been increased rapidly after 1985. The mother-child interaction studies were 13(38.2％) from the doctoral dissertation, 4(11.8％) from the Master's theses and 17(50％) other papers were published in academic journals. 2) Experimental studies of research design was used in these research studies was 13(38.2％). Descriptive studies was 8(23.6％), correlational studies was 4(11.8％) and comparative studies was 4(11.8％). Qualitative study was just one(2.9％) and literature review was 4(11.8％). Especially experimental studies has been increased. 3) Participants of these studies were mother and infant 29(85.5％), father and infant 2(5.9％), mother and fetus 2(5.9％) and nurse and infant 1(2.9％) 4) Utilization of instruments as follows: 13 studies used Walker et al(1986)'s MIPIS (Mother-Infant Play Interaction Scale), 6 studies used Barnard(1978)'s NCAFS (Nursing Child Assessment Feeding Scale), 4 studies used NCATS(Nursing child Assessment Teaching Scale) for assessing mother-infant interaction. 3 studies used Stainton(1981)'s Parent-Infant Interaction Scale. Choi(1987), Kim(1999) and Kim and Son(1997) used measurement tool researcher made which was modified from NCATS (Nursing child Assessment Teaching Scale) and AMIS(Assessment of Mother-Infant Sensitivity Scale). Other tools used to survey influencing factors of interaction. 5) Content of the research studies were classified 3 different types, such as ① studies about the mother-child interactions' pattern, ② studies about influencing factors of the mother-child interaction, ③ studies about effect of nursing intervention program to improve the mother-child interaction. Conclusion: Therefore we make following suggestions which are made based on the above research analysis : 1) In the future research studies need to compare with other area of discipline in mother-child interaction. 2) More attention and in depth research is needed to validate in terms of research design and statistical data analysis. 3) It is important to develop the instruments which is culturally acceptable in Korea society. 4) The results of correlational studies and experimental studies needs to the integrated by meta analysis.

The purpose of this study was to explore the effects of father's socio-demographic variables and father's literacy beliefs on father's literacy interaction. Participants were 204 fathers who have children in 3 to 5 years of age. Data were analyzed by descriptive statistics, correlation analysis and stepwise multiple regression analysis. The findings are summarized as follows: (1) Father's education level was generally correlated with 'father role efficiency', 'open interaction', 'picture-book reading interaction' (2) Monthly income of the household was related 'father role efficiency', 'positive feelings on reading books'. (3) 'Literacy ability development from books', 'father role efficiency', 'positive feeling on reading books' were correlated 'open interaction' and 'picture book reading'. But, 'literacy ability development from books', 'father role efficiency', 'positive feeling on reading books' were negatively correlated 'direct interaction'. (4) The most influential factor on father's 'open interaction', 'direct interaction' was 'literacy ability development from books'. The most influential factor on father's 'picture-book reading' was 'positive feeling on reading books'. These findings highlight that 'literacy ability development from books' and 'positive feeling on reading books' may play critical roles in father's literacy interaction. So, it is very important that adequate training and support on father's literacy beliefs for father's high quality literacy interaction.

인간은 항상 단순한 도구에서 복잡한 시스템에 이르기까지 수많은 물건과 관계를 맺으면서 생활하고. 있다. 여기에서 관계란 인간과 물건 사이에 이루어지는 상호작용으로 이러한 상호작용은 곧 사용자의 어떤 목적 달성을 위해 이루어지는 사용자와 제품 사이의 입출력과정으로 볼 수 있다. 이런 쌍방향적인 교류관계에서 중요한 것은 사용자 측면에서의 입력과 출력 그리고 제품 측면에서의 입력과 출력을 아무 문제없이 이어주는 것으로 비시각적인 제품의 조작과 반응사이의 관계를 좀 더 시각화하고 그 대응관계를 명료화하는 것이다. 따라서 이런 유형의 제품에서 제품개선의 의미는 무엇보다도 사용자와 제품간의 상호작용을 이해하고 분석하여 그 사이에 존재하는 물리적, 인지적 부하를 제거함으로서 사용자와 제품이 서로 무리없이 접근할 수 있도록 하는 것이다. 본 연구에서는 인간의 행동모형에 대한 고찰을 바탕으로 제품과 사용자와 상호작용을 시각화할 수 있는 틀을 만들고 이러한 틀을 이용하여 그 관계를 모델링하고 분석함으로서 인간중심의 제품개선을 위한 아이디어를 얻을 수 있는 방법을 논하였다.

The traditional computational fluid or structure dynamics analysis approaches have contributed to solve many delicate engineering problems. But for the most of recent engineering problems which are influenced by fluid-structure interaction effect strongly, traditional individual approaches have limited analysis abilities for the exact simulation. Owing to above-mentioned reason, nowadays fluid-structure interaction analysis has become a matter of concern and interest. FSI analysis require several unprecedented techniques for the combining individual analysis tool into integrated analysis tool. The Arbitrary Lagrangian-Eulerian(ALE, in short) method is the new description of continum motion,which combines the advantages of the classical kinematical descriptions, i.e. Lagrangian and Eulerian description, while minimizing their respective drawbacks. In this paper, the ALE description is adapted to simulate fluid-structure interaction problems. An automatic re-mesh algorithm and a fluid-structure coupling process are included to analyze the interaction and moving motion during the 2-D axisymmetric solid rocket interior FSI phenomena simulation.

Resonance occurrence conditions are explored by performing dynamic interaction analysis of arch bridge and KTX trains. The target bridge is a 3D tied-arch bridge having span length of 120m. KTX trains consist of two power carriages, two power and passenger carriages and sixteen passenger carriages. When KTX trains run on the target bridge with the uniform speed of 100 to 500km/h, the dynamic responses of the bridge induced by moving trains are obtained from railway arch bridge-train interaction analysis. Two resonance conditions are presented and whether the resonance phenomena occur or not at the suspicious resonance velocities is rigorously investigated through bridge deflections and accelerations and their FFT analysis.

CWR(Continuous Welded Rail) and bridge interaction produce rail force, bridge displacement and rail/bridge relative displacement. Each of these has limitation by many codes. In this paper, analysis of interaction has been carried out by using foreign codes(UIC 774-3 R code of Europe etc.) because there is no code about interaction between rail and bridge in Korea. Recently, railway bridges with CWR has been constructed for structural and economical reasons. When designer plans railway bridges, design a bridge model first and then investigate railway forces and displacement by interaction analysis. If these results go out bounds from limitation, designer plans railway bridges again and again. In this paper, using the parametric study on CWR and railway bridge interaction, railway bridge parameters such as length of bridge span, area of bridge, moment of inertia, stiffness of pier, etc. are presented. It helps preliminary design of railway bridges.

This paper investigates the modelling of coupled soil-structure interaction problems by domain decomposition techniques. It is assumed that the soil-structure system is physically partitioned into soil and structure subdomains, which are independently modelled. Coupling of the separately modelled partitioned subdomains is undertaken with various algorithms based on the sequential iterative Dirichlet-Neumann sub-structuring method, which ensures compatibility and equilibrium at the interface boundaries of the subdomains. A number of mathematical and computational characteristics of the coupling algorithms, including the convergence conditions and choice of algorithmic parameters leading to enhanced convergence of the iterative method, are discussed. Based on the presented coupling algorithms a simulation environment, utilizing discipline-oriented solvers for nonlinear structural and geotechnical analysis, is developed which is used here to demonstrate the performance characteristics and benefits of various algorithms. Finally, the developed tool is used in a case study involving nonlinear soil-structure interaction analysis between a plane frame and soil subjected to ground excavation. This study highlights the relative performance of the various considered coupling algorithms in modelling real soil-structure interaction problems, in which nonlinearity arises in both the structure and the soil, and leads to important conclusions regarding their adequacy for such problems as well as the prospects for further enhancements.

This study aimed to establish and validate the path models among faculty-student interaction, self-directed learning, and institutional commitment which impacted on the academic achievement of the university students. To achieve these goals, the survey results from 488 university students in North Gyungsang Province were analyzed. Descriptive analysis, correlation analysis, t-test, and path model analysis were performed to understand the relationship among variables. First, all the variables showed positive correlations except academic achievement and institutional commitment upon the study results. Second with respect to the differences by groups, faculty-student interaction and institutional commitment demonstrated the significant differences by sex while self-directed learning and academic achievement did not. Third on the path analyses, self-directed learning influenced to academic achievement directly, while faculty-student interaction did to it by mediating with self-directed learning and institutional commitment. The results of this study suggest that faculty-student interaction, self-directed learning, and institutional commitment perceived by the university students were significant elements on their academic achievements.
