  • 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.

  • This study examined the effect of sociodrama on children's loneliness and peer relations. Eight children each were assigned to an experimental or a control group. The experimental group enacted sociodrama for six weeks, and the control group did not have any treatment. The first post-test was conducted six weeks after the pre-test; the second post-test was eight weeks after the first post-test. Significant differences between the experimental and control groups were found for loneliness; that is, levels of loneliness and of negative peer relations decreased only in the experimental group. This effect for the experimental group was maintained at the second post-test. It was concluded that sociodrama was effective in reducing loneliness and in improving relationships of a child by improving self-adjustment.

  • An investigation of the effect of occupational information on vocational cognitive complexity was conducted with 331 male and female adolescents in ninth grade. There were 2 experimental groups and 1 control group. Experimental group I was given only occupational information sheets (written form information) while group II was given occupational information through verbal instruction in addition to the occupational information sheets. A modified form of the cognitive complexity grid originally developed by Bodden (1970) was utilized to collect data on the subjects' vocational cognitive complexity. ANOVA and $Scheff{\acute{e}}$ tests revealed that there were significant differences between experimental group II and the other groups in vocational cognitive complexity. The cognitive complexity level of experimental group I and the control group for the most aspired occupation was significantly lower than for the least aspired occupation. However, the cognitive complexity level of experimental group II for the most aspired occupation was higher than for the least aspired occupation. The results suggest that just giving occupational information to adolescents may not be effective and giving occupational information may be effective only when the method of giving occupational information is active enough to induce adolescents' self-confirming cognitive process.

  • This study aimed at analyzing the trend of re-search on pain in Korea, suggesting direction future pain research, and contributing to the use of pain interventions in nursing practice. Research studies on pain were selected from journals of medical and nursing schools, the Korean Nurse, the Korean Nurses' Academic Society Journal, the Central Journal of Medicine, the New Medical Journal, and from theses and dissertations, which were conducted between 1970 and 1994. The total number of the studies was 93. These studies were analyzed for 1) time of publication or presentation, 2) thesis for a degree or nondegree, 3) research design, 4) characteristics of subjects used in each study, 5) measurement tool, 6) types of correlated variables, 7) Korean terms for pain 8) types of nursing interventions, and 9) results of studies. The findings of the analysis can be summerized as follows : 1) The number of studies related to pain has increased rapidly since the early 1980's. The number of experimental research studies related to pain has increased chronologically, but the number of survey research studies related to pain was highest from 1981 to 1985, after that it decreased slowly. 2) The subjects in 19 studies were healthy people and, in 73 studies, patients with various illnesses. Thirty two studies were conducted with surgical patients. 3) Sixty one pain research studies were done for a thesis for a degree and 32 were nondegree research studies. 4) As measurement tools for pain, self- report pain scales were used in 54 studies and more than two tools were used in 28 studies. In the experimental studies, the trend was to use more than two tools. And in the nonexperirnental studies, the trend was to use self-report pain scales only. 5) There were 11 correlational studies. In these studies, the trend was to study anxiety, depression and variables such as intravenous infusion as related to pain.6) In the thirty six experimental studies, the effects of 16 types of nursing interventions weretested. Teaching and information, and relaxation technique were the most popular interventions for pain. 7) In eighteen methodological studies, the majority were studies testing the validity and re-liability of Dr. Lee's Korean Pain Rating Questionnaire. The following suggestions are made based on the above findings : 1) The patterns of these studies related to pain in Korea need to be compared with trends in other countries. 2) Meta - analysis should be done to analyze and integrate the results of various studies. 3) This analysis of pain research is needed to identify the present trend of pain research and to suggest the direction of future pain research, so these patterns of studies should be done in 5 to 10 year intervals. 4) More replicated pain research is needed to prove the effect of nursing interventions and more qualitative research on pain is needed to identify indepth the meaning of pain. 5) Pain researchers should make an effort to apply research result in various clinical settings and try to carry out team research with clinical nurses or with other multidiscipinary researchers.

  • In this paper, experimental studies of force tracking control for the crack sealing robot are presented. Crack sealing robot is built to detect, track and seal the crack on the pavement. Before sealing, crack must be detected by a laser sensor and a camera sensor, then cleaned for a better sealing job. In order to maintain contact with the ground force control is required to brush all dirt in the crack out for preparing sealing cracks with tars. Impedance control algorithm is presented to regulate a specified desired force. Experimental studies of the proposed force control algorithm are conducted under unknown environment stiffness and location. Performances of force control algorithm are stable and excellent.

  • The paper presents the experimental studies on the effectiveness of some vibration isolators developed for reducing transmission of vibration from the powered knapsack sprayer to the back and shoulders of the operator. A test rig was used to conduct detailed experimental studies on the powered knapsack sprayer mounted on it and fitted with different vibration isolators. Structural features of vibration isolators have been presented and their effectiveness of isolating transmission of vibration, from the engine-blower of the sprayer to its main frame and the operator, has been presented and discussed. Vibration measurements and analyses made by using B & K equipment have proved that the vibration isolators are quite effective in reducing the vibration transmission. The operators felt much less discomfort when they used the sprayer fitted with the isolators developed for the purposes, as compared to the existing arrangement.
