  • The purpose of this study was to evaluate the effect of informational intervention on postoperative pain following tonsillectomy in children. This study was performed on 30 children, aged 5-15 years, undergoing tonsillectomy and their parents by providing informational intervention with colored figure; operation procedure and information. Pain assessment was done by Pain Questionnaire. The results from this study were as follows : 1. Children in experimental group with mean 16.07 had lower pain scores than control group with mean 14.87 at 4th hours after operation(p<0.05). It showed 'significant difference' and first hypothesis was adopted. 2. Children in experimental group with mean 20.60 had lower pain scores than control group with mean 17.27 at 8th hours after operation(p<0.05). It showed 'significant difference' and second hypothesis was adopted. 3. Children in experimental group with mean 28.80 had lower pain scores than control group with mean 25.70 at 24th hours after operation(p<0.05). It showed 'significant difference' and third hypothesis was adopted. 4. When we analyzed the time difference and difference between two groups simultaneously by repeated measure ANOVA, the significant difference was not found. And so 'the experiential group with operation-related information will show the lower pain sense than the control group just as the time flows after operation', fourth hypothesis was rejected. Generally, it was found that providing information about operation to children and their parents reduced effectively postoperative pain in children, but in clinical settings there are minimum preoperative information-providing because of insufficient time and inconvenience although nursing staffs and patients know its needs. Conclusionally providing preoperative information should help children and their parents cope with Pre, Peri and Post operative events effectively.

  • The purpose of this study was to compare the metacognitive abilities of low and middle-achievers in elementary school. Forty-nine low-and fifty middle-achieving 6th graders were selected from two elementary schools in Seoul. The tower of Hanoi with three discs was used to explore the children's abilities. The subjects were asked to move the three discs on a post to another post five times. All children's performances on the Hanoi tower were video taped. KEDI-WISC, an intelligence test was also used to see whether the children's intelligence scores affect their performances. The results showed that: (1) there was no significant difference between the two groups in the rate of success for the tasks; (2) low-achievers took more time to finish the tasks than middle-achievers, but the time difference decreased dramatically after the first trial; (3) no significant differences was found in self monitoring abilities, though the low-achievers needed more time to start monitoring themselves; (4) low-achievers had much more difficulty in representing the tasks; (5) the IQ scores of the middle-achievers were significantly higher than the low-achievers, but the IQ scores of low achievers were more scattered than those of middle-achievers; that is, IQ scores significantly affected the performance of the children.

  • This study evaluated the content of Korean vocabulary learning applications with a focus on tablet PC applications. We analyzed 51 Korean vocabulary learning applications. The instruments in this study were developed based on Yoo et al. (2012)' Vocabulary Learning Game Application Evaluation Criteria and Hyun et al. (2013)' Educational Application Evaluation Criteria. Data were analyzed using a t-test and one-way analysis of variance. The main results are as follows. First, each criteria's score was fairly good; the ease of use had the highest scores and the amusement had the lowest scores. Second, there was a significant difference in the interaction by vocabulary teaching approach. Applications based on a whole language-teaching method had higher scores than applications based on a phonics instructional teaching method inducing more operation and with immediate feedback. Third, there was significant difference in the sum of score and each criteria of developmental appropriateness, educational values, amusement, function and interaction by type of learning. Applications of combining type had higher scores in every criteria except for ease of use than applications of description type. These findings provide a preliminary evidence that the systematic Korean vocabulary learning application facilitates preschoolers' vocabulary learning.

  • This study investigated the effect of supportive nursing care including modified guided imagery on the discomfort, self- esteem, erythrocyte semdimentation rate(ESR) and quality of life(Q. L.) in persons with rheumatoid arthritis (R. A.). The purpose was to contribute to the development of theoretical nursing care to enhance the Q. L. of persons with chronic illness. From Nov. 22, 1990 to May 2, 1991, 49 patients registered at a rheumatic clinic at one general hospital in Seoul, were accepted according to the research criteria as subjects for this study. Among these, 26 were selected for an experimental group to he treated with an interpersonal interview and modified guided imagery, the other 23 became the control group not treated for the purpose of measuring and comparing the effect of the treatment. Statistical analysis was done by a SAS program for X$^2$-test, unpaired t -test, Pearson correlation coefficients and factor analysis. The results were as follows : 1. The pre-experimental discomfort level of the total subject group averaged 25.42(S. D. =8.77), and the difference between the pre /post experimental discomfort levels of the two groups was not statistically significant. 2. The pre - experimental self- esteem scores of the total subject group averaged 27.48(S. D. =3.95), and the difference between the pre /post experimental self -esteem scores of the two groups was not statistically significant. 3. The pre - experimental Q. L. scores of the total subject group averaged 28.70(S. D. =5.99), and the difference between the pre /post experimental Q. L. score of the two groups was statistically significant (t=2.1748, df=47, p= .0347), 4. The pre - experimental mean of the ESR of the total subject group was 34.48(S. D. =19.50) mm, and the difference between the pre /post expeimental ESR scores of the two groups was not statistically significant. 5. The Family support scores of the total subject group averaged 41.28(S. D. =10.27). 6. The total subject group 0.L. score was correlated with self-exteem score (r= .3984, p= .0046). In this study, supportive nursing care including modified guided imagery increased the quality of life scores for this group of persons with R. A. significantly. So the concept of supportive nursing care of this study may be effective in enhancing the quality of life persons with chronic illness. Further investigations related to the methodology and with other groups of clients was recommended.

  • In this thesis we concerned with the degree of similarity in pairs of scores having a common mean and variance could express similarity in terms of the absolute difference between the standardized scores. We particulary discussed the distribution of absolute differences between pairs of T scores among many standardized scores and demonstrated the procedures for calculating the lower limit of Med(│d│) values i. e. the maximum possible similarity with medians and correlation coefficients of the equivalent form tests by using the folded normal distribution, although other researchers expressed the degree of similarity using only the standard normal distribution. We also described many cases how to use those techniques and to apply effectively them in real evaluation fields.

  • The study examined the effects of San-Yin-Jiao(SP-6) acupressure treatment on labor pain, length of delivery and anxiety for women in the labor. The effects of using SP-6 acupressure were evaluated by comparing two groups, a SP-6 acupressure group (22) and a control group (17), for a total of 39 women in labor who had a normal vaginal delivery. Data were collected using a structured questionnaire which included general characteristics, a subjective labor pain scale, measurement of duration of delivery time and a subjective anxiety scale. Data were collected before treatment (pre) and after treatment (post). The results of this study are summarized as follows : 1. The post-scores for total labor pain increased over the pre-scores but the difference between the two groups was not statistically significant(p=0.219). Wilcoxon signed rank test of the difference in pre-post labor pain scores for the SP-6 acupressure group was not statistically significant (p=0.081) but the increase for the control group was statistically significant (p=0.001). 2. The length of time for the delivery in the group which had the SP-6 acupressure was shorter (143.91${\pm}$67.77) than the control group (197.94${\pm}$89.64). The difference between the two groups was statistically significant (p=0.028). 3. The post-scores for anxiety increased over the pre-scores but the difference between the two groups was not statistically significant (p=0.426). The scores of SP-6 acupressure group did not show a significant increase by the Wilcoxon signed rank test (p=0.194) but in the control group showed a significant increase (p=0.008).This study showed that SP-6 acupressure was effective in relation to labor pain, length of time for delivery and anxiety for labor women. But it is necessary to replicate the study with a larger number of participants to generalize the results.

  • Functional recovery of cerebrovascular accident (CVA) patients were studied by examining functional independence measure (FIM) to evaluate the functional state of the patients at admission to and at discharge from the hospital and its relationship with the family support. Study subjects consisted of 129 CVA patients, who were admitted and received rehabilitation treatment at K Medical Center of Oriental Medicine from August 3 to December 18, 1997. The results were as follows: 1) Total FIM score was $72.37{\pm}25.16$ at admission and $101.67{\pm}22.13$ at discharge. The difference of average score was 29.30, which was statistically significant by paired t-test. 2) The largest difference between FIM scores at admission and at clischarge was observed in items of walking and wheel-chair riding, and the smallest clifference in items of social interaction. 3) The recovery was faster with motor function than with cognitive function, because the difference of FIM scores at admission and at discharge was much larger with motor function. 4) Recovery was better in groups under age 49 than in groups above age 70. Functional recorvery was prominent especially in groups with normal sensory state and speech functions, and groups without urinary incontinence. Recovery was less significantly in patients with paraplegic patients hospitalized longer than 2 months, patients with family all the time, and patients with CVA over 11 days. 5) We could not find any relationship between functional recovery and family support. FIM scores were lower in groups of old age(r=-0.325), long stayed in hospital (r=-0.426), and long period of time after the onset of disease(r= -0.339) with a reciprocal correlation between FIM scores and these parameters. 6) Stepwise multiple regression analysis was done to evaluate factors to affect the recovery from CVA. FIM score at admission could explain 51.2 % of the functional recovery. Important factors were periods of hospitalization, state of sensory function, age, and education (listed in decreasing order of importance). In total, they could explain 64.89% of the functional recovery. These results indicate that functional recovery of CVA patients, who were admitted to oriental medicine hospital for rehabilitation treatment, could be estimated by measuring FIM scores. Recovery was significantly better at discharge from the hospital than at admission and motor function recovery rate was much faster than that of cognitive function. 2. Recommendation Based on these results, we recommend following further studies. 1) Comparative study of recovery of motor function and of sensory function would be necessary by measuring FIM scores once a week to evaluate the recovery of CVA patients. 2) It would be interesting to see whether there is any difference of functional recovery between patients treated with either western medicine or oriental medicine. 3) Psychological factors affecting the recovery of CVA patients need to be studied.

  • This study examined how well Korean undergraduate students perceived linked or clear English speech and attempted to find areas of difficulty in their English listening caused by phonological variations. Thirty nine undergraduate students participated in listening sessions. They were divided into high and low groups by their TOEIC listening scores. Samples of linked speech included such phonological processes as linking, palatalization, flapping, and deletion. Results showed that the students had more problem perceiving linked speech than perceiving clear speech. Secondly, both the higher and the lower groups scored low on the linked speech. The lower group had more score difference between linked and clear speech. Thirdly, the students' scores increased from the speech with flapping, through deletion, palatalization, to linking. Finally, there was a strong positive correlation between their TOEIC listening scores and the perception scores. Further studies would be desirable on the level of improvement of TOEIC scores by training the students' listening ability using the linked speech.

  • Background: The aim of this study was to evaluate the efficacy of Korean medicine combination treatment on recurrent neck pain after medical procedures. Methods: This retrospective study included 158 inpatients of the Daejeon Jaseng Hospital of Korean Medicine who were diagnosed with "Cervical disc disorder with radiculopathy (M50.1)" between December 14th, 2017 and May 29th, 2019. The patients were assigned to 1 of 2 groups based on whether they received medical procedures on the cervical spine at least once. Korean medicine combination treatment was evaluated using EuroQol-5 dimensions index (EQ-5D), numeric rating scale (NRS), and neck disability index (NDI) scores. Results: Before and after treatment, the patients who received medical procedures on the cervical spine at least once before admission (Group A) showed a statistically significant difference in the NDI and NRS scores but not in the EQ-5D scores. This was similar to the patients who had not received medical procedures on the cervical spine before admission (Group B) they showed a statistically significant difference in the NDI and NRS scores but not in the EQ-5D scores. When comparing the results of Group A and Group B before and after treatment, no statistically significant differences were observed in the EQ-5D, NDI, and NRS scores. Conclusion: Korean medicine combination treatment improves the neck functional disability of patients who suffer from recurrent neck pain despite patients having undergone medical procedures.
