This study set out to investigate the relations between middle school students' perception of body image and their allowance for plastic surgery, to understand their perception of body image and desire for plastic surgery, and provide some data needed to warn against reckless plastic surgery and guide the students effectively. For those purposes, an examination was conducted of the relationships between the individual characteristics and perception levels of body image, the individual characteristics and allowance for plastic surgery, and perception levels of body image and allowance for plastic surgery. The subjects were drawn from sour middle schools located in two regions of Gyeonggi Province. Total 922 boys and girls were surveyed on a questionnaire, which was developed based on the pretest of previous literature, reviewed for appropriateness, and tested for reliability and reasonableness. The body image on the five scale was greater as the perception level was higher. The allowance for plastic surgery was also greater as the scores were more. The findings were as follows: First, the relationships between individual characteristics and perception levels of body image were examined. The third graders showed the highest perception level, being followed by the first and second graders. The girls were more perceptive than the boys, and those who were extrovert were more perceptive than those who were introvert. Those students whose parents earned 2 million won or more a month and who adapted themselves to the environmental changes had a higher perception level. In a word, the girls from the middle class that were well adapted, felt happy, and were extrovert had a higher perception level of body image. Second, the connections between individual characteristics and allowance for plastic surgery were investigated. The third graders were the most admissive of plastic surgery, followed by the second and first graders. That is, the upper graders were more admissive of plastic surgery. In addition, the girls were more admissive than the boys, and those who were extrovert were more than those who were introvert. There were no significant differences according to the monthly income of the parents, grades, adaptability to surroundings, and happiness, which results almost resembled the findings of a study conducted on adults. Third, there were negative correlations found between the perception levels of body image and the allowance for plastic surgery. To elaborate, the higher the perception levels were, the lower the allowance was, and vice versa. As for the items, the subjects showed more allowance for plastic surgery when they scored less in the item of caring about appearance, importance of looking pretty to others, and efforts to improve appearance. When they had a low value of body and easily felt tired, they were highly acceptive of plastic surgery. The allowance for plastic surgery was also great when their perception was much of how healthy they felt, how important they felt about their bodies, how they were satisfied with their current appearances, how they evaluated the appearance of others, how much they were satisfied physically, and how much demanding they were for physical changes. Meanwhile, there were no correlations between the allowance and physical attraction, the degree for one's activities to be hindered, and sickness. In short, the demand for plastic surgery was 41% for the girls and 20.2% for the boys. Just as the study on adults reported, those who had a low or negative perception of body image were more acceptive of plastic surgery. The middle school students were generally positive about their bodies with the lowest perception level at 2.91 and the highest at 3.21. Their individual allowance for plastic surgery was related to their individual body images, which were in turn affected by the mass communication, surrounding environments, and social values. Thus it's necessary for the entire society to try to improve or change the overall perception. Helping measures should be taken so that the students can form right sense of values about their bodies, avoid the obsession with appearance and appearance-based evaluation, and exercise righteous criteria against humans beings and things. In conclusions, the following suggestions were made: they need to develop such questionnaires or tools as can measure the body image of teens and fit the reality. Moreover, body image improvement programs should be more diverse and more applicable to teens. Despite the consistent reports that prove the correlations between body image and plastic surgery, there has been little effort to apply such factors as experience of the life of the disabled, volunteer activities for the disabled and at the hospitals, and others that can induce changes to body image to the body image improvement programs. In the future, comparative research should be carried out on body image and plastic surgery.

Aging population is a global trend and Korea is no exception. Due to the progress of the medical and scientific sectors, increase in the average lifetime incurred increase in the number of elderly people. Meanwhile, the family function of supporting the elderly has become a major issue in a society due to the changes in the society's structure and increased entry of the women into the workforce. As a means to substitute the protection of the elderly who are not protected at their respective homes and to replace the tending needs, weekly protection centers and short-stay centers for the elderly were established and operated in Seoul since 1992. However, structured and satisfactory services are not yet to be provided, thus this research intends to understand the current situation at the short-stay centers for the elderly, to identify users' characteristics and to conduct study on nursing need for the health reasons so that the results of the research can be utilized as basic data for the development of nursing care program. Towards this end, this research targeted 142 elderly people who were undergoing treatment at the 11 short-stay centers for the elderly out of total of 13 located in Seoul that were willing to cooperate. The research was conducted from April to May 2002, with the measurement tool developed by Rhee, Seon-ja (2001) to measure the level of nursing need. Then data was collected and analyzed using SPSS program. The results are as follows. The general characteristics of users of the short-stay centers for the elderly were: 123 females $(86.6\%)$, 19 males $(13.4\%)$ and 72 elderly were over the age of 80 $(50.7\%)$. Among these, 24$(16.9\%)$ were living by themselves. Among the illnesses that the subjects were inflicted with were: dementia $(54.2\%)$, stroke $(54.1\%)$ and high blood pressure $(50.7\%)$, in the respective order. Despite the fact that they were diagnosed with illnesses, $47.2\%$ responded that they do not undergo special treatment due to financial reasons. When the level of needs for nursing care among the elderly who use the short-stay centers is divided into informational. physical. and emotional need levels and scored between zero to two, the level of emotional need is the highest with 1.80, followed by physical (1.45) and informational (1.44) need levels. As for the realities of services at the centers and improvement areas, restriction on term was cited as the greatest inconvenience with $38.7\%$, followed by lack of budget (24 respondents, $16.9\%$). Wishful services were financial assistance $(46.5\%)$, medical and nursing services $(40.1\%)$, meal provision service $(8.5\%)$ and counseling service $(4.9\%)$, in the respective order. Based on the above mentioned results, the research identified the need to develop nursing program for the patients of dementia that can be applied onto the short-stay centers and the need to develop volunteer service, backed by societal support. Also, placement of specialized cadre of professionals is needed so that medical and nursing service functions can be provided in a complementary manner.

The purpose of this study is to present the basic data needed to improve the arts, music, and physical education provided by local child care centers based on an investigation of the current status of and satisfaction with the education. The subjects of this study were 17 local child care centers in Gyeonggi-do, South Korea, and the situation of the arts, music, and physical education programs operated from 2014 to 2016 were examined. In addition, 419 children who received the education were surveyed to evaluate their level of satisfaction. The results of this study are as follows. As regards the status of the arts education from 2014 to 2016, it was observed that three of the 17 local child care centers did not have any arts, music or physical education at all, while six of them continuously implemented all three of these programs during this period of time. Two and six of the 17 institutes had arts, music, and physical education programs for two years and one year, respectively. All of the teachers who ran the arts and music education programs of the 17 institutes were arts and music majors who were certified teachers of the liberal arts. However, the physical education programs were run as volunteer activities by college students majoring in physical education. The survey on the level of satisfaction of the children who participated in the arts, music, and physical education programs showed that they were helpful for the overall life experience of the children and that they were more helpful for the boys than for the girls. The level of satisfaction with the education was high for most of the students who participated in the programs, however the boys were more satisfied than the girls. When asked whether they would participate in the arts, music, and physical education programs again, most of the respondents answered that they would do so. The boys were more likely to participate again than the girls. Based on this study, in order to enhance the creativity and personality education of the children using the local child care centers, higher quality education is needed. Arts and music education can be used to help children to learn to communicate smoothly with their friends. In addition, it seems to be necessary to enhance the education by setting goals that are suitable for its purpose, in order to provide creative arts and music education that contributes to the physical health and emotional stability of the children.

Purpose : Instead of conventional two-dimensional (2-D) visual stimuli, three-dimensional (3-D) visual stimuli with stereoscopic vision were employed for the study of functional Magnetic Resonance Imaging (f-MRI). In this paper f-MRI with 3-D visual stimuli is investigated in comparison with f-MRI with 2-D visual stimuli. Materials and Methods : The anaglyph which generates stereoscopic vision by viewing color coded images with red-blue glasses is used for 3-D visual stimuli. Two-dimensional visual stimuli are also used for comparison. For healthy volunteers, f-MRI experiments were performed with 2-D and 3-D visual stimuli at 3.0 Tesla MRI system. Results : Occipital lobes were activated by the 3-D visual stimuli similarly as in the f-MRI with the conventional 2-D visual stimuli. The activated regions by the 3-D visual stimuli were, however, larger than those by the 2-D visual stimuli by $18\%$. Conclusion : Stereoscopic vision is the basis of the three-dimensional human perception. In this paper 3-D visual stimuli were applied using the anaglyph. Functional MRI was performed with 2-D and 3-D visual stimuli at 3.0 Tesla whole body MRI system. The occipital lobes activated by the 3-D visual stimuli appeared larger than those by the 2-D visual stimuli by about $18\%$. This is due to the more complex character of the 3-D human vision compared to 2-D vision. The f-MRI with 3-D visual stimuli may be useful in various fields using 3-D human vision such as virtual reality, 3-D display, and 3-D multimedia contents.

Purpose : To demonstrate that the relaxographic method provides additional information such as the distribution of relaxation times and water content which are poentially applicable to clinical medicine. Materials and Methods : First, the computer simulation was performed with the generated relaxation data to verify the accuracy and reliabilility of the relaxographic method (CONTINI). Secondly, in or der to see how well the CONTIN quantifies and resolves the two different ${T_1}$ environments, we calculated the oil to water peak area ratios and identified peak positions of ${T_1}-distribution$ curve of the phantom solutions, which consist of four centrifugal tubes (10 ml) filled with the compounds of 0, 10, 20, 30% of corn oil and distilled water, using CONTIN. Finally, inversion recovery MR images for a volunteer are acquired for each TI ranged from 40 to 1160 msec with TR/TE=2200/20 msec. From the 3 different ROIs (GM, WM, CSF), CONTIN analysis was performed to obtain the ${T_1}$-distribution curves, which gave peak positions and peak area of each ROI location. Results : The simulation result shows that the errors of peak positions were less in the higher peak (centered ${T_1}=600$ msec) than in the lower peak (centered ${T_1}=150$ msec) for all SNR but the errors of peak areas were larger in the higher peak than in the lower peak. The CONTIN analysis of the measured relaxation data of phantoms revealed two peaks between 20 and 60 msec and between 500 and 700 msec. The analysis gives the peak area ratio as oil 10%: oil 20%: oil 30% = 1:1.3:1.9, which is different from the exact ratio, 1:2:3. For human brain, in ROI 3 (CSF), only one component of -distributions was observed whereas in ROI 1(GM) and in ROI 2 (WM) we observed two components of ${T_1}-distribution$. For the WM and CSF there was great agreement between the observed ${T_1}-relaxation$ times and the reported values. Conclusion : we demonstrated that the relaxographic method provided additional information such as the distribution of relaxation times and water content, which were not available in the routine relaxometry and ${T_1}/{T_2}$ mapping techniques. In addition, these additional information provided by relaxographic analysis may have clinical importance.

WiFi fingerprinting is well known as an effective localization technique used for indoor environments. However, this technique requires a large amount of pre-built fingerprint maps over the entire space. Moreover, due to environmental changes, these maps have to be newly built or updated periodically by experts. As a way to avoid this problem, crowd-sourced fingerprint mapping attracts many interests from researchers. This approach supports many volunteer users to share their WiFi fingerprints collected at a specific environment. Therefore, crowd-sourced fingerprinting can automatically update fingerprint maps up-to-date. In most previous systems, however, individual users were asked to enter their positions manually to build their local fingerprint maps. Moreover, the systems do not have any principled mechanism to keep fingerprint maps clean by detecting and filtering out erroneous fingerprints collected from multiple users. In this paper, we present the design of a crowd-sourced fingerprint mapping and localization(CMAL) system. The proposed system can not only automatically build and/or update WiFi fingerprint maps from fingerprint collections provided by multiple smartphone users, but also simultaneously track their positions using the up-to-date maps. The CMAL system consists of multiple clients to work on individual smartphones to collect fingerprints and a central server to maintain a database of fingerprint maps. Each client contains a particle filter-based WiFi SLAM engine, tracking the smartphone user's position and building each local fingerprint map. The server of our system adopts a Gaussian interpolation-based error filtering algorithm to maintain the integrity of fingerprint maps. Through various experiments, we show the high performance of our system.

Purpose: increased uptake of wrist and hand joints in three phase bone scintigraphy (TPBS) have been used in the detection of reflex sympathetic dystrophy syndrome (RSDS). TPBS frequently shows increased shoulder uptake in the hemiplegic RSDS patients. We investigated the significance of the shoulder uptake in the detection of these patients. Materials and Methods: Twenty three patients who had hemiplegia due to brain stroke and diagnosed as RSD were enrolled in this study (M:F=16:7, R:L=11:12). The mean age was $63{\pm}10$ yrs. Ter normal volunteer (mean age: $60{\pm}5$, M:F=1:9) data was used as control group. TPBS was performed $59{\pm}32$ days after stoke (acute stage). We obtained the count ratios of bilateral hands by drawing a region of interest (ROI) in three phase images and compared to the count ratios of shoulders in the delayed image. Hand ROI included an ipsilateral wrist. Sensitivity of detecting the affected limb was defined using the right/left count ratio of normal control. Results: Sensitivities using count ratios of hand blood flow, blood pool and delayed image were 45%, 76% and 78%, respectively. Sensitivity of shoulder count ratio was 74%. Log of right/left counts of hand delayed image and that of shoulder delayed image were correlated well with statistical significance (Spearman's R=0.824, p<0.001). Conclusion: Shoulder uptake showed good correlation with hand uptake in the delayed image of TPBS. Shoulder uptake maybe helpful in the diagnosis of reflex sympathetic dystrophy syndrome in patients with hemiplegia.

Purpose: This study was to identify the death recognition, meaning in life, and death attitude of participants in the death education program. Methods: A survey was conducted, and 205 data were collected. Descriptive statistics, ${\chi}^2$-test, ANOVA, and Duncan test were used. Results: 1) The followings were the characteristics of death recognition shown by the participants. Over half of the participants said that they had given some thoughts on their deaths, that they had agreeable view on death acceptance, and that diseases and volunteer works made them think about their deaths. Moreover, suffering, parting with family and concerns for them, etc. were the most common reasons for the difficulty of accepting death. As for 'the person whom I discuss my death with', spouse, friend, and son/daughter were the most chosen in this order. Lastly, the funeral type that most of the participants desired was cremation. 2) The means of meaning in life and death attitude were $2.92{\pm}0.29$ and $2.47{\pm}0.25$, respectively. There were significant differences between health status, meaning in life and death attitude. 3) A significant positive corelationship was found between meaning in life and death attitude (r=0.190, P=0.001). Conclusion: For an effective death education program that would fit each individual's situation, an educational content that can make a person understand the meaning of his or her life and death, includes knowledge to lessen the fear and anxiety of death, and helps a person heal from the loss of a family member is absolutely necessary.

Background: It is well known that rifampin decreases the hypoprothrombinemic effect of warfarin by induction of cytochrome P-450 enzyme in healthy volunteer. However, in patients the dosage schedule of warfarin during rifampin therapy is not established. Therefore, patients taking both rifampin and warfarin were reviewed to find out the adequate dosage schedule of warfarin in addition to side effects by interaction of two drugs. Method: Patients taking both rifampin and warfarin were retrieved from patients who were admitted due to heart disease and tuberculosis at Boochun Sejong Hospital from January of 1995 to August of 1999. To decide the adequate dosage of warfarin, the dosage of warfarin before, during, and after rifampin was evaluated in patients who kept adequate hypoprothrombinemic effect of warfarin during rifampin. To decide the adequate dosage schedule of warfarin, the time interval from the beginning of rifampin to normalization of prothrombin time(INR$\geq$1.1) was evaluated. And, the side effects by interaction of two drugs were reviewed. Results: All 12 patients taking both rifampin and warfarin were retrieved. Among them only 6 kept adequate hypoprothrombinemic effect of warfarin during rifampin. The dosage of warfarin during rifampin was $2.4{\pm}0.6$(mean$\pm$standard deviation) times as much as that before rifampin but the dosage after rifampin was the same as that before rifampin. The time interval from the beginning of rifampin to normalization of prothrombin time was $5.8{\pm}2.9$(mean${\pm}$standard deviation) days. 2 out of 12 had complication related to the interaction of rifampin and warfarin, one cerebral embolism just after the beginning of rifampin and the other cerebral hemorrhage just after the discontinuation of rifampin. Conclusion: When both rifampin and warfarin are prescribed, it would be a possible method to be confirmed by prospective study that warfarin be gradually increased about 2 times more than that without rifampin over 1 week or so after the beginning of rifampin and be tapered to the same dosage as that before rifampin when rifampin is discontinued. And, it would be prudent that prothrombin time be monitored frequently during rifampin and warfarin therapy, especially the beginning or discontinuation of rifampin.

Objectives : To evaluate the effects of Head Acupuncture versus Upper and Lower Limbs Acupuncture on signal activation of Blood Oxygen Level Dependent(BOLD) fMRI on the Brain and Somatosensory Cortex. Subjects and Methods : 10 healthy normal right-handed female volunteer were recruited. The average age of the 10 subjects was 30 years old. The BOLD functional MRI(fMRI) signal characteristics were determined during tactile stimulation was conducted by rubbing 4 acu-points in the right upper and lower limbs($LI_1$, $LI_{10}$, $LV_3$, $ST_{36}$). After stimulation of Head Acupuncture in Sishencong($HN_1$), $GB_{18}$, $GB_9$, $TH_{20}$ of Left versus Upper and Lower Limbs Acupuncture($LI_1$, $LI_{10}$, $LV_3$, $ST_{36}$ of Right) and took off needles. Then the BOLD fMRI signal characteristics were determined at the same manner. Results : 1. When touched with cotton buds(sensory stimulation), left Parietal Lobe, Post-central Gyrus, primary somatosensory cortex(BA 1, 2, 3), and primary motor cortex(BA 4) were mainly activated. When $ST_{36}$ was stimulated, Frontal Lobe, Parietal Lobe, Cerebellum, and Posterior Lobe as well as Inter-Hemispheric displaying a variety of regions. 2. In signal activation before and after Head Acupuncture reaction, it showed signal activation after removing the acupuncture needle and right Somatosensory Association Cortex, Postcentral Gyrus, and Parietal Lobe were more activated. 3. In reactions of before and after Upper and Lower Limb Acupuncture, it also showed signal activation after removing the acupuncture needle and bilateral Occipital Lobe, Lingual Gyrus, visual association cortex, and Cerebellum were activated. 4. After acupuncture stimulation, In Upper and Lower Limb Acupuncture Group, left frontal Lobe, Precentral Gyrus and Bilateral parietal lobe, Postcentral Gyrus and Primary Somatosensory Cortex(BA 2) were activated. In Head Acupuncture Group, which has most similar activation regions, but especially right Pre-Post central Gyrus, Primary Somatosensory Cortex(BA 3), Primary Motor Cortex, frontal Lobe and Parietal Lobe were activated. Conclusions : When sensory stimulation was done with cotton buds on four acup-points($LI_1$, $LI_{10}4, $LV_3$, $ST_{36}$), while bilaterally activated, contralateral sense was more dominant. It showed consistency with cerebral cortex function. When $ST_{36}$ was stimulated Frontal Lobe, Parietal Lobe, Cerebellum, Posterior Lobe as well as Inter-Hemispheric were stimulated. In Head Acupuncture, it showed more contralateral activation after acupuncture. In Upper and Lower Limb Acupuncture, it showed typically contralateral activation and deactivation of limbic system after acupuncture stimulation. Therefore, there were different fMRI BOLD signal activation reaction before and after Head Acupuncture vs Upper and Lower Limb Acupuncture which might be thought to be caused by acu-points' sensitivity and different sensory receptor to response acupuncture stimulation.
