Backgrounds : In 2017, National Health Insurance implemented the pilot insuring project for Chuna manual therapy(CMT). 65 Korean Medicine(KM) hospitals and clinics were selected in the project to monitor the provision of insured CMT. Objectives : This study aimed to evaluate the effectiveness of CMT for low back pain provided in the real world setting. Methods : Patients with low back pain who agreed to participated in the study were enrolled and requested to complete questionnaires. Patients who received CMT regardless of receiving other KM therapies were classified to Chuna group, and patient who received KM therapies without CMT to KM group. Pain(pain-VAS) and back function(KODI, Oswestry disability index-Korean version), quality of life were assessed at baseline, 4 weeks, and 8 weeks. Additionally, patients who received CMT twice and more, and who's pain-VAS 20 and over were included, and patients who used pain injection were excluded in the analysis. Results : Of 371 patients who completed all questionnaire (mean age=42.6years, SD=12.45; 61% female), 96 were excluded, 170 were in Chuna group, and 105 were in KM group. Proportions of patients who had low back pain for more than twelve weeks in the Chuna group and KM group were 57.7% and 24.8%, respectively. Pain and back function were significantly improved on 4weeks and 8weeks in both groups, but there was no difference between two groups. For the patients in the sub-acute and chronic stage(>=12 weeks), change of total KODI scores in the Chuna group was higher than KM group(p=0.013) at 4weeks. Conclusions : CMT with other KM therapies can improve back function in the sub-acute and chronic patients. For insurance policy decision, economic evaluation of CMT is needed.

Background: There are practical difficulties to show exact clinical symptoms such as seizure to medical students at Clinical Performance Examination (CPX). We developed a new CPX case of child's seizure on video using smartphone. Methods: A total of 356 $4^{th}-year$ students of five universities in Daegue-Gyeongbuk and Gyeongnam area took the clinical skill examination from June $13^{th}$ to $17^{th}$ in 2016. Among them, 72 students took the new CPX case in June $15^{th}$ and 71 students filled out the questionnaire on whether the new CPX with smartphone video is helpful, authentic, difficult, and necessary for other CPX. All the questions were measured on 5-Likert scale. Results: Mean score of the new CPX was 57.1, lower than the mean scores of the other 11 CPX cases, 62.8. For the question "Smartphone videos helped to solve the problem", 45 students (63.4%) answered 'Very much'. For the question "Is it realistic compared to other questions?" 30 students (42.3%) and 25 students (35.2%) answered 'Very much' and 'Much'. For the question "Is it difficult compared with other questions?" 18 students (25.4%) and 26 students (36.6%) answered 'Very much' and 'Much'. As for the question "I would like to have more tests using smartphone video", 26 students (36.6%) answered 'So and so'. Conclusion: A majority of students responded that video presentation was helpful and authentic to figure out the CPX, whereas they assessed smartphone video was more difficult compared with other CPXs. Further, students were negative toward using smartphone video for the other CPXs.

Purpose : Although lung ventilation SPECT (LV-SPECT) has a good sensitivity in detection of deep lung lesions, it is difficult to apply the LV-SPECT to patients having breathing problems due to limited examination time. In this study, we evaluated the usefulness of LEAP collimator, which provides high detection sensitivity and tolerable resolution, for the LV-SPECT in terms of diagnostic accuracy and examination time. Materials and Methods : Four volunteers inhaled Technegas (370 MBq) and the lung ventilation planar scan (LVPS, 300 counts/view (cpv)) with LEHR collimator was performed using Siemens E.cam scanner as a reference test. LV-SPECT scans were performed with three collimators, LEHR, LEUHR, and LEAP, in low (7 kcpv) and high (70 kcpv) counting modes. The count ratios of left (LT) and right (RT) lung segments were calculated on the geometric mean view of anterior and posterior images for LVPS and on the summed coronal images of LV-SPECT, respectively. Comparing to LVPS, the usefulness of three different collimators for LV-SPECT was evaluated through statistical analysis (paired t-test), on count ratios of lung segments. Results : The average LT:RT ratio in LVPS was 47:53. For LV-SPECT, there were negligible difference of the LT:RT ratios (48:52 on average) among three different collimators in low and high counting modes. Comparing to standard LVPS with LEHR, all LV-SPECTs with different collimators resulted in similar diagnostic accuracy through paired t-test (p>0.05). The scan time in LVPS (6 views) was 17.3 min. For LV-SPECT (128 views) in low counting mode, it took 18.7 (LEUHR), 15.0 (LEHR), and 12.3 min (LEAP), respectively. Conclusion : Comparing to standard LVPS, the LV-SPECT with LEAP in low counting mode provided the comparable diagnostic accuracy in addition to shortened scan time.

Purpose : We performed this study to compare the TSH and free $T_4$ levels according to gestational age and birth weight, and to reevaluate the cut-off values in the neonatal screening test for congenital hypothyroidism. Methods : Total 2,133 neonates(1,749 healthy newborns and 384 sick neonates) were screened in Dankook University Hospital from May 2000 to January 2003. Neonates with abnormal TSH values (higher than $20{\mu}IU/mL$) or abnormal free $T_4$ levels(lower than 1 ng/dL) were recalled to recheck the thyroid function test. At that time, physical examinations and history-taking regarding perinatal problem, medication history, and mother's illness were undertaken. Results : Serum TSH and free $T_4$ values revealed no significant difference according to sex, delivery type, and Apgar score. The free $T_4$ levels showed statistically significant differences, with gestational age or birth weight(P<0.01). The recall rate of neonates due to abnormal screening test was 7.48 percent. Compared with original cut-off values, the recall rate of the new cut-off values setted to TSH higher than $20{\mu}IU/mL$ or free $T_4$ lower than 0.64 ng/dL decreased from 7.48 percent to 4.8 percent in the healthy group. But, it compromised sensitivity when applied to the sick group. Conclusion : In this study, neonatal free $T_4$ levels were significantly different according to birth weight, gestational age, and the presence of compromised condition. Although the recall rate by TSH > $20{\mu}IU/mL$ or free $T_4$ <1 ng/dL was relatively high, it was impossible to set up new cut-off values without compromising sensitivity. We think studies including a larger study population will be required to change the cut-off values.

A study was carried out to improve the feeding practice of Korean native goats. Ten goats were used in this study to obtain basic information needed for the determination of energy and nitrogen requirements for maintenance and growth. The results obtained were as follows. 1. The daily gain of male and female goats were $80{\pm}13.9g(\bar{x}{\pm}S.E.)$ and $41{\pm}8.9g$, respectively. 2. The amounts of orchardgrass hay and formula feed consumption by goats were 0.60-0.75% and 1.80-2.80% of their body weights, respectively, when fed ad libitum. The daily consumption of orchardgrass hay by goats when fed alone was 1.98-3.16% of their body weights. 3. The amounts of metaholizable energy needed for daily maintenance were 61.6, 65.0 and $72.3Kcal/BW_{kg}{^.75}$ at the live weights of 30, 21 and 12kg, respectively. 4. The daily nitrogen requirements for maintenance were 7.07, 4.67 and $3.04g/BW_{kg}{^.75}$ at the live weights of 30, 21 and kg, respectively. 5. Daily energy retention was 138 kcal/head and nitrogen retention rate was 13.3-22.5%.

Though human being has ability to percept a full colored vision, the technology of early photography only can produce black and white images. For cinema filming imagery also captured mono tone with black and white, until developed a color film technology. The desire for presenting color imagery and the technique for producing film and color ink, photography and print utilize color on it with noticeable color impact to viewers. It, however, abusing fun colors image each and every printed and filmed imagery, the freshness of eye catching power diminished now. On contrast, color becomes black and white or partially used for making discrepancy among full colored images. This image detected commercial and music video, and it spread to film. To use those bleached color images is for evoking a nostalgia and a visual differentiation. Especially, it can be provocative images brought to audience with that. such as "Anycall", "Dimchae" for CF, and "Schindler's list," and "Sin city" for movie. It is hard to investigate on the color studies for partially used images. Therefore, this study is to research that through CF and film, base on it, to investigate the application for this image. To collect data from survey, it will be established a basic concept for understanding the partial color applying.

This study was conducted to investigate the actual state of use and necessity of Korean traditional Pyebaeck foods using questionnaire. The subjects of this study consisted of 621 housewives in Daegu area. The results were summarized as follows: The most often used foods of Pyebaeck refreshments included alcoholic drinks(80.0%), Bamgoim(73.8%), Daechugoim(73.4%). The refreshments were most often purchased from caterers(39.6%), and mainly used for marriages of their brothers and sisters(33.3%). The standard number of foods prepared was 7 to 10(42.2%). The most used container for Pyebaeck refreshments is bamboo basket(30.6%). 62.0% of the respondents needed Pyebaeck refreshments and the reason for refreshment preparation was mainly “because it is a Korean tradition”(82.3%) and the reason why most respondents do not think the Pyebaeck refreshments are necessary was “it's troublesome and complicated”(41.1%). The refreshments most frequently included were alcoholic drinks(63.7%) and Daechugoim(47.0%). Most of the respondents(84.9%) said that the Pyebaeck refreshments should be improved and 48.0% said the improvement method should consider the traditional tastes, flavors and arrangements fit to modem sense. Although following the traditions of Pyebaeck refreshments itself is difficult, the concept of Pyebaeck refreshments can develop into a modern concept with new meaning if we improve and adjust it in a way fit to modem lifestyles.

Purpose：The aim of this study was to evaluate the striatal binding ratio, the anterior/posterior ratio and reproducibility using a template based registration method using the standard MR template as a replacement for each patients MR image. Materials and Methods：This study analyzed the 123I IPT SPECT images of 30 patients with IPD, who were subdivided into 17 patients (56.6$\pm$10.8 yr, M/F : 8/9.) with mild IPD, and 13 patients (56.4$\pm$11.1 yr, M/F : 8/5) with severe IPD. In addition, 11 normal controls (57.8$\pm$14.4 yr, M/F : 4/7) were also analyzed. The ROIs were positioned manually in the same slice showing the highest striatal activity using the traditional manual method, whereas those were positioned automatically in a mid striatal slice of the SPECT image coregistered to the standard T1 weighted MR template. Results : The specific binding ratio (SBR) obtained using the template based registration method strongly correlated with those using the manual method in all groups : normal controls (r=0.85, P<0.001), mild IPD (r=0.84, P<0.001) and severe IPD (r=0.7, P=0.01). The SBRs obtained using both methods were significantly different among the three groups (P=0.05) and the SBRs obtained by the template based registration method were higher than those by the manual method (P=0.05) in all three groups. The APRs obtained by the template based registration correlated with those using manual method in only mild IPD (r=0.72, P=0.0). The APRs obtained by the template based registration method were significantly different from the normal controls and those with mild or severe IPD (P<0.05), whereas those obtained using the manual method were not significantly different among the three groups (P＞0.1). The reproducibility (rmsCV) of the template based registration method was 7.2% (normal controls：5.2%, mild IPD：4.2%, severe IPD：10.8%), whereas the reproducibility of the manual method was 31% (normal controls：19.7%, mild IPD：21.7%, severe IPD：46.2%). Conclusion：These results show that the use of $^{123}$ I-IPT SPECT for assessing IPD is affected by the methods used to position the striatal ROI. The template based registration method using the standard MR template can be useful in diagnosing IPD and assessing the disease severity with a high reproducibility. Therefore, the template based registration method appears to be a good replacement for the manual method.

The purpose of this study is to evaluate the contribution of $^{18}$ F-FDG brain PET in the differentiating Idiopathic parkinson's diesease (IPD), progressive supranuclear palsy (PSP), and multiple system atrophy (MSA). We studied 24 patients with parkinsonism : 8 patients (mean age 67.9$\pm$10.7 y: M/F : 3/5) with IPD, 9 patients (57.9$\pm$9.2 y : M/F : 4/5) with MSA and 7 patients (67.6$\pm$4.8 y : M/F 3/4) with PSP. All patients with parkinsonism and 22 age-matched normal controls underwent $^{18}$ F FDG PET in 3D mode after the injection of 370 MBq $^{118}$ F FDG. The patients with IPD, MSh and PSP were compared with a normal control group by a two-sided t-test of SPM99 (uncorrected P<0.001, extent threshold>100 voxel). All three parkinsonism groups, showed significant hypometabolism in the cerebral neocortex compared to the normal control group. However, the three groups displayed different metabolism in the subcortical structure, brain stem, and cerebellum. In IPD, there was no significant hypometabolism in the putamen, brain stem and cerebellum. However, MSA patients showed significant hypometabolism in the striatum, pons, and cerebellum compared to the normal controls and IPD patients. In addition, PSP showed significant hypometabolism in the caudate nuclei, the thalamus, midbrain, and the cingulate gyrus compared to the normal controls, the IPD, and MSA groups (IPD vs Normal sensitivity/specificity : 75%/l00%, MSA vs Normal sensitivity/specificity :100%/87%, PSP vs Normal sensitivity/specificity : 86%/94%). Our results show that the regional metabolism of IPD, MSA, and PSP is different mainly in the striatum, thalamus, brain stem and cerebellum. An assessment of the $^{18}$ F-FDG PET scan images using SPM may be a useful adjunct to a clinical examination in making a differential diagnosis of Parkinsonism.
