The purpose of this study was to identify the interaction patterns in distance only mode e-Learning. In order to investigate this study, messages shown in the electronic notice board were analyzed to see how interaction occurs between teacher and learner or learner and learner under the e-learning of cyber university. To analyze messages was applied according to the framework by Henri's contents analysis model. As a result of contents analysis on electronic board, the participative dimension was 399 messages. A learner put on 7~8 messages a day. The number of messages was low compared to the number of learners, but the number of inquiries was about 140. That means that each learner contacts and checks messages at least once a day. The meaning dimension was 600 units. The main interaction patterns were Interactive-social-cognitive-metacognitive. This means that e-Learning in distance only mode leads a positive attitude of learners as a self-directed learning, and needs teacher's well-structured instructional strategies for increasing interaction. In conclusion, social dimension and interactive dimension of messages support learners psychologically in the process of learning though they directly guide learning under the circumstances of e-learning lacking face-to-face element. It can be interpreted that the teacher's role is significantly important in order to attract learners' positive participation and cognitive and meta-cognitive dimension of messages and activities

This study presents the Family FIRO model for stepfamily development. The Family FIRO model conceptualizes interactional patterns in stepfamily for dealing with developmental tasks and suggests a method for organizing assessment and for prioritizing treatment strategies. Boundary ambiguity role confusion intergenerational coalition and loyalty conflict lack of relationship commitment and resource management issues of stepfamily constitute the inclusion interaction dimension in The Family FIRO model. While power role negotiation conflict decision making and discipline issues represent the control interaction dimension lack of emotional exchange and open self-disclosure issues are intimacy interaction dimension in the stepfamily. The family FIRO model suggests that stepfamily should attend to the developmental tasks related to inclusion before placing a major emphasis on control issues which in turn should come before emphasis on stepfamily intimacy.

The intrinsic viscosities were determined for poly(DL-lactic acid) (PDLLA) solutions in 1,2-dialkyl phthalate at temperatures ranging from 30 to $60^{\circ}C$. A series of dialkyl phthalate, in which the alkyl group was changed from methyl to propyl, was used as the solvent to control the solvent quality systematically. The intrinsic viscosity of the PDLLA solution was higher in the better quality solvent, with a higher molecular weight of PDLLA, and at lower temperatures. The unperturbed dimensions of the PDLLA molecule and polymer-solvent interaction parameter of PDLLA in dialkyl phthalate were deduced using extrapolation methods based on the temperature-dependent intrinsic viscosities. Slight shrinkage in the unperturbed chain dimension was observed, which resulted from a change in polymer conformation with temperature. It was also observed that the polymer-solvent interaction became more favorable with the dialkyl phthalate containing a shorter alkyl chain.

The purpose of this study were 1) to find out impression dimensions of the dress wearer with various motifs 2) to evaluate the impression effects of motifs in Korean traditional dress for women. The research method was a quasi-experimental with the between subjects design. The experimental materials developed for the study were a set of stimuli and response scale. The stimuli were consisted of 12 drawings with full factorial design of 3 independent variables : motif sorts (2:flower animal) motif types(2: realistic stylized) motif arrangements(3: all over the traditional to modern) The stimuli consisted of color photographs and color of clothing and motifs was controlled the blue. The response scales were consisted of 30 bi-polar adjectives. The subjects were 333 undergraduate college students of Taejon. The data was analyzed by factor analysis MANOVA and Duncan's multiple range test. Results were as follows: 1. The wearer's impression were consisted of the 3 different dimensions : attractiveness · dignity dimension. Interaction effect among motif sorts motif types and motif arrangements was significant on the same dimension. Interaction effect between motif sorts and motif arrangements was significant on the visibility dimension. 3. The motif arrangements were a significant variable on the attractiveness·dignity and the evaluation dimension. The traditional arrangement and the modern arrangement showed more faborable impression and the all over arrangement showed less favorable impression on the attractiveness·dignity dimension. The all over arrangement showed positive impression on the evaluation dimension and the traditional arrangement and the modern arrangement showed negative impression on the same dimension. There were no significant difference between flower sort and animal sort and also no significant difference between realistic type and stylized type in their impression effects.

The purpose of this study is to systematize the theory of the father-child relationship by analyzing the father's role and father-child interaction. The results of this study are as followings: (1) The oedipal period 3 to 5 years is a critical in development of the father-child relationship. Father absence is assumed in infancy but it is denying because the father participates in Child- rearing activity. (2) The Father's role is symbolized instrumental role traditionally and culturally but it is appropriate that we think the father's role to be androgynous concepts. Instrumental role as well as expressive role is expected to father's role. (3) The role of the father is supplementary mother's role. The father provides economic, emotional support and helps the balanced child- rearing. This indirect role of the father is very important. (4) The father influences child development, and his role is to be sex-role model to contrieve personality internalize moral development. But it is needed more empirical study to clarify father's effects on child development. (5) The amount of time that fathers spend with their children is less than mothers, but it is not assumed that difference of this amount of time do not differently influence to the children. (6) There are much similarity that difference between father-child interaction and mother- child interaction. Qualitative difference in interaction is response style. A responsive style of the father is physical intellectual instructive but mother's is verbal. (7) The effects of the father to a child must be analyzed on dyadic dimension and triadic dimension of family network. In triadic dimension, father influences mother- child relationship, mother to response sensitively, husband-wife relation.

본 연구에서는 선박조종시뮬레이터를 이용하여 선박의 크기에 따른 두 선박의 간섭력의 운동특성을 분석하였다. 파나막스급 컨테이너선이 자선보다 크기가 작은 계류선을 근접통항하는 경우에 계류선에서 간섭력의 피크점과 운동패턴의 변화가 뚜렷하게 나타났다. 이땐 선박의 정횡 상태 전후에서 전후력과 회두모멘트가 반대방향으로 바뀌므로 계류선의 움직임에 각별한 주의가 요구된다. 반대로 파나막스급 컨테이너선이 자선보다 큰 계류선을 통과하는 경우에는 근접상황이 발생하는 초기에 통과선에서 간섭력의 피크점이 나타났고, 통과선에는 정횡 이후 약 1L(통과선의 전장)의 구간동안 지속적으로 흡인력이 발생했다. 또한, 통과선과 계류선의 선체간의 수평거리가 2B(통과선의 폭)이하로 줄어들면, 통과선의 초기에 발생하는 간섭력이 급격히 증대된다.

Purpose: The purpose of this study was to define and clarify the concept of political competence for nurses. Methods: A hybrid model method was used to investigate the dimensions, attributes, and definitions of the concept. In the theoretical stage of the study, literature on nursing, politics, and other discipline were reviewed. In the fieldwork stage, individual in-depth interviews and focus groups interviews were conducted with politically seasoned experts or activists who had an understanding of the concept of political competence for extensive descriptions in nursing and field of health care. Results: The concept of political competence was represented in four dimensions as political knowledge, political efficacy, political interaction, and political activity. In the political knowledge dimension, there were three attributes, namely, political knowledge, political information and systematic analysis ability. The political efficacy dimension had three attributes of internal political efficacy, external political efficacy, and self-pride of nursing profession. The political interaction dimension had three attributes of organizations and community service, networking, and persuasive power. The political activity dimension had six attributes of political leadership, political expression, assertive behavior, political advocacy, political participation, and policy intervention. Conclusion: This concept development might provide a basic understanding of developing a measurement tool and for constructing a theory promoting nurses' political competence.
