Purpose: To determine the incidence of post-concussion syndrome (PCS) in Korean patients after minor traumatic brain injury. Methods: We conducted an observational cohort study of a convenience sample of patients presenting to the emergency department of a major academic Korean hospital. Patients who visited the Emergency Department for head trauma were screened. A researcher questioned the subject regarding his or her symptoms. Subjects were contacted by phone approximately 2 weeks after their Emergency Department visit and questioned about subsequent symptoms and subsequent visits for medical care. Results: Only 8% of subjects reported any post-concussion symptoms. Only 0.4% had three or more symptoms which might have met criteria for PCS. The median peak onset of symptoms was 3 days after injury. Conclusion: The incidence of PCS is Korean patients is much lower than that documented for patients in the United States or other western countries. On the other hand, this study results could give an idea that mild trauma could also cause the PCS. Further study is needed to replicate this finding and investigate possible explanations for this difference.

The purpose of this study is to analyze error patterns third-year middle school students make on quadratic function graph problems and to examine about the possible correct them by providing supplementary tutoring. To exam the error patterns that occur during problem solving processes, to 82 students, We provided 25 quadratic function graph problems in the preliminary-test. The 5 types of errors was conceptual errors, false intuition errors, incorrect use of conditions in problems, technical errors, and errors from slips or carelessness. Statistical analysis of the preliminary-test and post-test shows that achievement level was higher in the post-test, after supplementary tutoring, and the t-test proves this to be meaningful data. According to the per subject analyses, the achievement level in the interest of symmetry, parallel translation, and general graph, respectively, were all higher in the post-test than the preliminary-test and this is meaningful data as well. However, no meaningful relation could be found between the preliminary-test and the post-test on other subjects such as graph remodeling and relations positions of the parabola. For the correction of errors, try the appropriate feedback and various teaching and learning methods.

These days, as the society has been in the trends of highly industrialized and the family has been downsized, there is remarkably increasing number of women who follow occupation. These changes have made it more difficult for the family to help post-partum mother, which had been performed in side of house. By the help of social believe that during at least 1 month after childbirth professional nursing program is indispensable for both maternity protection and physical-mental recuperation, now many post-partum care centers for post-partum mother have been in operation. Although these post-partum care center have in use for a long time, no study was performed before this study on the same subject. Data were analyzed using by SAS. The results of study are as follow : 1. The general features of the user of the post-partum care center. The predominant band of user's age is extended from 26 to 30. The users are mainly housewives and they are in higher level of incomes and educations. As for the feature of delivery methods, they performed the normal spontaneous vaginal delivery method by 58.0% and the Caesarean operation method by 42.0%. As for the sexuality for babies, 59.3% of infants are male, and 40.7% are female. The highest delivery order of users is first and admission after 1-3days delivery is highest. 2. The results for the investigation into the actual condition of the post-partum care center are as follow : About the main reason for entrance of the post-partum care center was found to be the needs for the better nursing programs for recuperation after childbirth. This demands are also supported by their husbands. The average length of stay in the post-partum care center is 17.6 days and the besides promised expense ; powdered milk, milk-suckers, disposable dippers, skin cares, body shape cares, entrophics, injections. The post-partum have private rooms for mother and infants. Over the half of average expense is 229 million won. They are paying accessory fees the post-partum care center have similar step organization : the nurses, the skin carers, the cleaners. Mostly both ways of feeding powdered milk and breast feeding are in use, and mother's milk is preserved in the night time to be given to infant by nurse in charge. 3. The results of the investigation on users' nursing demand to the post-partum care center and satisfaction are as follow : The ranking order of nursing demand of mothers who used the is that ; infant care demands, environmental demands, emotional and mental care demands, education and training demands. As much as 70% of the respondents have dissatisfaction in nursing program, The ranking order of service satisfaction of mothers who used appears to be higher following order ; satisfaction in infant care demand, satisfaction in physical nursing demand, satisfaction in emotional and mental nursing demand, satisfaction in education and training demand, satisfaction in environment nursing demand. The results of pearson correlation. between nursing demand and service satisfaction of mothers who used are found to be relative noticeable in the level of 0.05. only infant care. The 61.7% of the women who used the post-partum care center. are responding that they will reuse the same post-partum care center again.

When a rigid post is exposed to traffic, it is hazardous not only to head-on impacts but also to side impacts. Clip-type slip base is an effective measure to reduce the severity of head-on impacts and side impacts as well because of its multi-directional release mechanism. Side impact tests were conducted and the results were analysed to demonstrate the hazardousness of a rigid post to a side impact and the crash worthiness of a post having clip-type slip base. For that, side impact test standard was made adapting the NCHRP Report 350, and 820kg-50km/h side impact tests were made for posts of D101.6mm(t=4.2mm) with and without slip base. Additionally, 35km/h side impact to the same post with slip base was conducted to check whether the clip-type slip base release mechanism works properly to the low impact speed. The tests revealed that the rigidly connected post was very hazardous to side impact while the post with the clip-type slip base reduced the impact severity tremendously.

Purpose : This study aimed to investigate the effect of blood flow restriction exercise on ankle muscle strength and balance ability to achieve maximum efficiency with the same exercise intensity and time. Methods : Twenty-six adults are randomly assigned to experimental group (n=13) and comparison group (n=13). The experimental group performed ankle joint strength exercises with blood flow restriction applied while the comparison group performed ankle joint strength exercises without blood flow restriction applied three times a week for four weeks. The digital muscle measurement, Y-balance test, and Cumberland ankle instability tool were used to evaluate the subject's muscle strength, dynamic balance, and ankle instability index before and after the intervention. Results : In within-group comparison muscle strength, all the two groups showed significant improvements post intervention (p<.05). In between-group comparison, there was significant difference in the change of dorsiflexion, eversion strength pre and post intervention (p<.05). but plantarflexion was no significant difference between pre and post intervention in the group comparison (p>.05). In within-group comparison dynamic balance, all the two groups showed significant improvements post intervention (p<.05). In between-group comparison, there was no significant difference in the change of Y-balance score pre and post intervention (p>.05). In within-group comparison ankle instability index, all the two groups showed significant improvements post intervention (p<.05). In between-group comparison, there was no significant difference in the change of CAIT score pre and post intervention (p>.05). Conclusion : The results of this study show that ankle joint strength exercise improved the strength and balance ability of those complaining of chronic ankle instability, and ankle joint strength exercise applied with blood flow restriction was more effective in dorsiflexion and eversion strength exercise than ankle joint strength exercise without blood flow restriction.

The art education in the latter period of the 20th century was conducted in the same cramming method as education of expressionism and pragmatism from beginning to end, while post-modernism can be interpreted as a viewpoint of reflecting the diversity, popularity and needs of the era. Under such circumstances, this research is aimed at looking for an educational method that can reflect the educational method of this present period. Thus, this research is trying to analyze the works of some artists showing a variety of styles of the post-modernism period and to inquire into a new direction at a viewpoint of the post-modernism where divers cultures co-exist. This research considered these artists' works as the objects for comparison because there exists an aspect of something in common in that there are more diverse-style-based expression in the post-modernism art education though their subject and format are different individually. Therefore, this research is conducted at a viewpoint of assisting in the understanding of more diverse style-based painting in the post-modernism education.

In this paper, I examined the representation of post-colonialism focusing on the spaces in Modern Boy and Assassination. These movies represented Bon-jung and Jong-no as a mixed-residence quarter, over the dual city theory, the orthodoxy of geography. It can be interpreted as the birth of a hybrid subject in post-colonialism. The representation of Bon-jong in Modern Boy was centered around Mitsukoshi Department Rooftop Garden, Namsan Music Center and Myeongdong Cathedral. The representation of Bon-jung in Assassination was centered around Anemone Cafe and Mitsukoshi Department Store. Set in the history of the new building the Japanese Government General of Korea in Jong-no, Modern Boy used it as a place of struggle. The representation of Jong-no in Assassination was centered around the mansion of Kang In-kuk, a pro-Japanese collaborator. Modern Boy and Assassination showed the post-colonialism that breaks through modern binary oppositions by a 'female' national heroine. describing Bon-jung as both a mixed-residence quarter and the original home of post-colonialism movement, they also showed a different aspect from the existing Kyung-sung representations.

The pharmacokinetics/pharmacodynamics analysis software NONMEM$^{(R)}$ output provides model parameter estimates and associated standard errors. However, the standard error of empirical Bayes estimates of inter-subject variability is not available. A simple and direct method for estimating standard error of the empirical Bayes estimates of inter-subject variability using the NONMEM$^{(R)}$ VI internal matrix POSTV is developed and applied to several pharmacokinetic models using intensively or sparsely sampled data for demonstration and to evaluate performance. The computed standard error is in general similar to the results from other post-processing methods and the degree of difference, if any, depends on the employed estimation options.
