Background: Patients with COPD generally complain of very different degrees of dyspnea regardless of their pulmonary function. The study, we assessed the right ventricular ejection fraction in relation to dyspnea in COPD patient. Methods: The pulmonary function including the diffusion capacity was measured. The right ventricle ejection fraction (RVEF) was measured using a first-pass radionuclide scan by multigated acquisition (MUGA). Forty patients with chronic obstructive pulmonary disease (COPD) were stratified for dyspnea according to the Medical Research Council (MRC) scale. Moderate dyspnea and severe dyspnea is defined as MRC 2/3 (n = 16) and MRC 4/5 (n = 24) respectively. Results: The baseline pulmonary function tests including DLCO and the resting arterial blood gas were similar in the moderate and severe dyspnea group, with the exception of the residual volume (% predicted) (moderate $160{\pm}27$, severe $210{\pm}87$, p < 0.03). The right ventricle ejection fraction was significantly (p < 0.001) lower in the severe dyspnea group ($25{\pm}8$) than in the moderate group ($35{\pm}6$). The independent factor assessed by multiple logistic regression revealed only the severity of dyspnea to be significantly associated with RVEF (p < 0.02). Conclusion: This study showed that the right ventricle ejection fraction would contributes to severity of dyspnea in patients with a similar pulmonary function.

The purpose of this study was to examine changes in the swallowing function with chronic stroke patient. Ten chronic stroke patients with dysphagia followed up for 3 months. Eight normal age match subjects were also participated. A total of 18 participated in this study and they were classified into two groups (stroke patient group and normal control group). Participants underwent videofluoroscopic swallowing examination. The swallowing function was evaluated over time. Oral transit duration, pharyngeal transit duration, laryngeal response duration, Modified Barium Swallowing Impairment Profile ($MBSImP^{TM(c)}$), and Functional Oral Intake Scale (FOIS) were applied. Chronic stroke patient group were showed significantly longer oral transit duration, pharyngeal transit duration and laryngeal response duration than normal control group at baseline. After 3 months in stroke patient group, the mean oral components score of MBSImP (1~5) significantly decreased and the mean score on FOIS increased compared to baseline. In conclusion, oral swallowing function and oral intake function improved by the 3 month evaluation. These results describe changes in swallowing function with chronic stroke patients over time and provide basic informations to understand dysphagia.

To minimize CT examination for Hip FAI diagnosis and operation plan. also, whether the MRI 3D images can replace Hip Clock face image was evaluated when performing Hip FAI MRI by using additional 3D image. This study analyzed Hip MRI and 3D Hip CT images of 31 patients in this hospital. For the purpose of evaluating the images, one orthopedic surgeon and one radiology specialist reconstructed Clock face, at MR and CT modality, by superior 12 o'clock, labrum front 3 o'clock, and the other side 9 o'clock, centering on Hip joint articular transverse ligament 6 o'clock. Afterwards, by the Likert Scale 5 point scale (independent t-test p<0.005), this study evaluated the check-up of A. retinacular vessel, B. head neck junction at 11 o'clock, A. Epiphyseal line, B. Cam lesion at 12 o'clock, and Cam lesion, Posterior Cam lesion at 1,2,3 and 4 o'clock. As for the verification of reliability among observers, this study verified coincidence by Cohen's weighted Kappa verification. As a result of Likert scale for the purpose of qualitative evaluation about the image, 11 o'clock A. retinacular vessel MR average was $3.69{\pm}1.0$ and CT average was $2.8{\pm}0.78$. B. head neck juncton didn't have a difference between two observers (p <0.416). 12 o'clock A. Epiphyseal line MR average was $3.54{\pm}1.00$ and CT average was $4.5{\pm}0.62$(p<0.000). B. Cam lesion didn't have a difference between two observers (p <0.532). 1,2,3,4 Cam lesion and Posterior Cam lesion were not statistically significant (p <0.656, p <0.658). As a result of weighted Kappa verification, 11 o'clock A.retinacular vessel CT K value was 0.663 and the lowest conformity. As a result of coincidence evaluation on respective item, a very high result was drawn, and two observers showed high reliability.

Purpose: This study was to explore barriers to effective pain management in general population. Methods: Total 163 Participants completed the Barrier Questionnaire-II (BQ-II), a 27-item on a six point scale, from May to June in 2007. BQ-II consisted of four subscales which were 1) physical effects (PE) addressing beliefs that side effects of analgesics are inevitable and concerns about tolerance, fatalism (Fa) addressing fatalistic beliefs about cancer pain and its management, Communication (Co) addressing the beliefs of 'good patient' and concerns of distracting physician from underlying disease, and harmful effects (HE) addressing fear of addiction and harmful effect to immune system of pain medicine. Results: The BQ-II total had an internal consistency of 0.877 in this study. HE was the biggest barrier (3.03) followed by PE (2.73), Fa (2.15), and Co (1.71). Items appeared as great concerns were 'there is a danger of becoming addicted to pain medication'(3.58), 'using pain medicine blocks your ability to know if you have any new pain' (3.18), 'pain medicine is very addictive' (3.09), 'when you use pain medicine your body becomes used to its effects and pretty soon it won't work any more' (3.09), and 'drowsiness from pain medicine is difficult to control' (3.09). Only 12 respondents (7.4%) reported that they took any type of pain education, however, those who took pain education represented significantly lower barriers to pain management than who did not (P=.029). Conclusion: This result suggests the strategies for public education to surmount cancer pain.

This study aimed to identify binge-eating behavior and food addiction in Korean population and to determine their associations with obesity, eating behaviors, mental health and cognitive characteristics. We collected clinical questionnaire scores related to eating problems (e.g. binge eating, food addiction, food cravings), mental health (e.g. depression), and cognitive functions (e.g. impulsivity, emotion regulation) in 257 Korean adults in the normal and the obese weight ranges. Binge-eating and food addiction were most frequent in obese women (binge-eating: 46.6%, food addiction: 29.3%) when we divided the participants into 4 groups depending on gender and obesity status. The independence test using the data with propensity score matching confirmed that binge-eating and food addiction were more prevalent in obese individuals. Finally, we constructed the logistic regression models using forward selection method to evaluate the influence of various clinical questionnaire scores on binge-eating and food addiction respectively. Binge-eating was significantly associated with the clinical scales of eating disorders, food craving, state anxiety, and emotion regulation (cognitive reappraisal) as well as food addiction. Food addiction demonstrated the significant effect of food craving, binge-eating, the interaction of obesity and age, and years of education. In conclusion, we found that binge-eating and food addiction are much more frequent in females and obese individuals. Both binge-eating and food addiction commonly involved eating problems (e.g. food craving), but there was difference in mental health and cognitive risk factors. Therefore, it is required to distinguish food addiction from binge-eating and investigate intrinsic and environmental risk factors for each pathology.

The 18~20G needle is used to computer tomography (CT) contrast examination. Therefore, a patient has to apply a self-administering hemostasis (conventional method: CM) and often experience bleeding in the course. Thus, we developed the new disposable transparent tourniquet (TT) for reducing. This study was to compare the usefulness between the proposed transparent tourniquet and the existing hemostatic methods. A Satisfaction survey was conducted by 50 patients and 25nurses. The survey contained the satisfaction of the convenience, safety, sanitation, and wearing sensation of transparent tourniquet. We employed face-to-face interview on 5 points likert scales. And Chi-square, paired T-test were used for the statistics verification. As for the patients, the satisfaction levels were measured for each category with the gender, age. Patients evaluation, overall satisfaction high average sore used TT and there were statistical significance by paired T-test(p<0.05). The following is the average satisfaction level for each category: $4.4{\pm}0.53$ in; $4.28{\pm}0.57$ in safety; $4.52{\pm}0.54$ in sanitation; $4.16{\pm}0.54$ in wearing sensation. So the overall satisfaction level is measured at $4.34{\pm}0.51$. As for the nurses, CT work experience and the current satisfaction with tourniquet were counted as variables. The satisfaction level for each category is: $3.8{\pm}0.7$ in; $3.6{\pm}0.68$ in safety; $3.4{\pm}0.5$ in sanitation; $3.9{\pm}0.49$ in hemostasis. The overall satisfaction level is $3.8{\pm}0.3$. Patients' satisfaction levels were very high with little difference among variables. Nurses' satisfaction levels were different with the TT depending on their work experience but their overall satisfaction was high. This TT will be a starting point to minimizing patient's inconvenience and more studies are necessary to enhance their satisfaction.

Purpose: Diversity and the lachrymal duct deformities and the passage inside the nasal cavity except for anterior image such as epiphora happens during the test were able to express more precisely during the dacryoscintigraphy. Also, we thought about the necessity of a method to classify the passage into the naso-lachrymal duct from epiphora. Therefore, we are to find the validity of the method to obtain both oblique views except for anterior views. Materials and Methods: The targets of this research are 78 patients with epiphora due to the blockage at the lachrymal duct from January 2013 to August 2013. Average age was $56.96{\pm}13.36$. By using a micropipette, we dropped 1-2 drops of $^{99m}TcO4^-$ of 3.7 MBq (0.1 mCi) with $10{\mu}L$ of each drop into the inferior conjunctival fold, then we performed dynamic check for 20 minutes with 20 frames of each minute. In case of we checked the passage from both eyes to nasal cavity immediately after the dynamic check, we obtained oblique view immediately. If we didn't see the passage in either side of the orbit, we obtained oblique views of the orbit after checking the frontal film in 40 minutes. The instrument we used was Pin-hole Collimator with Gamma Camera(Siemens Orbiter, Hoffman Estates, IL, USA). Results: Among the 78 patients with dacryoscintigraphy, 35 patients were confirmed with passage into the nasal cavity from the anterior view. Among those 35 patients, 15 patients were confirmed with passage into the nasal cavity on both eyes, and it was able to observe better passage patterns through oblique view with a result of 8 on both eyes, 2 on left eye, and 1 on right eye. 20 patients had passage in left eye or right eye, among those patients 10 patients showed clear passage compared to the anterior view. 13 patients had possible passage, and 30 patients had no proof of motion of the tracer. To sum up, 21 patients (60%) among 35 patients showed clear pattern of passage with additional oblique views compared to anterior view. People responded obtaining oblique views though 5 points scale about the utility of passage identification helps make diagnoses the passage, passage delayed, and blockage of naso-lachrymal duct by showing the well-seen portions from anterior view. Also, when classifying passage to naso-lachrymal duct and flow to the skin, oblique views has higher chance of classification in case of epiphora (anterior:$4.14{\pm}0.3$, oblique:$4.55{\pm}0.4$). Conclusion: It is considered that if you obtain oblique views of the bilateral orbits in addition to anterior view during the dacryoscintigraphy, the ability of diagnose for reading will become higher because you will be able to see the areas that you could not observe from the anterior view so that you can see if it emitted after the naso-lachrymal duct and the flow of epiphora on the skin.

This study attempts to examine the principles of landscape composition for a 'Suhwon(書院)' and the meaning and value of its traditional landscape architecture, in order to apply the results to the design of modern landscape architecture. A 'Suhwon' is a vital space containing the form and meaning of human activity. This study analyzes the characteristics of landscape composition in the construction of the Namgea Suhwon, located in Hamyang, by examining the form and meaning of its area and composition. The Namgea Suhwon was constructed with a suitable configuration and harmony in a good location, neither field nor mountain, and which encompasses transcendence and a return after passage through a period of birth and abundance. Its appearance means 'life existence and hidden death(生居死幽)'. Its spatial system is a reflection of the idea of Samshinoje(三神五帝: The three abilities of Providence and its five subjects) connected with Ilsangje -Samshin -Ohje. It was built based on the idea of Biryebudong(非禮不動) meaning that one should follow only good decorum and avoid discourtesy, complying with "the frame of decorum" developed by the family rites of Chu Hsi. The environmental design of the Namgea Suhwon was interrupted by the material confrontation between mountains and water and a binary code system, such as front to rear, length to breadth, and movement to stillness. The design did not adhere to stiff axes, but pursued the harmonic principles of asymmetric balance in the building and the yard, which are very naturalistic. The name 'Namgea Suhwon' is closely related with the view of placement(置) and harmony(和), which are unified with the function and meaning formed by connecting Sung Confucianism with the Pungsu-Sasinsa structure in the layout of the grounds. When examining the D/H ratio of the building and yard, it can be seen that the spaces of Ganghak, Yusang and Jehyang were built appropriately, according to the natural characteristics of each space, such as a sense of openness, enclosure, tension, relief, enhancement, and hierarchical order. The spaces also reflect human scale concepts that take advantage of auditory features. The transition process after the construction of 'Namgea Suhwon' reveals the intentions of the builder to create an ecological landscape composition based on Placement and Harmony. Placement embodies' a purposeful space in which nature and the building are connected naturally, 'incomplete open space pursuing completion', and 'potential beauty in which tension and relaxation are repeated'. Harmony embodies 'order and continuity having a sense of unity with the natural environment' and the 'sharing of daily life and memory'. 'Namgea Suhwon' contains many ideas for landscape planning, land use and the design of a campus environment.

The present study was performed to investigate the effect of iohexol-ethanol mixture and barium-ethanol mixture on the induction of transcatheter renal artery embolization in healthy 18 dogs, which were divided into two groups of 9 dogs and the 9 dogs were divided into 3 subgroups of 3 dogs. The renal artery embolization was undertaken unilaterally with the dose of 1.5, 2.0, and 3.0 ml/kg iohexol-ehtanol mixture and with the dose of 0.2, 0.4, and 0.8 ml/kg barium-ethanol mixture. And serum chemistry on 0, 1,3, 7, and 14 days, intravenous pyelography on 7days, angiography on 14 days, and histopathology on 14 days were evaluated. Serum BUN and creatinine concentration of two groups with iohexol-ethanol mixture and barium-ethanol mixture administration were mildly increased a t 1 day after injection of embolic materials and then returned to baseline. No significant changes in BUN and creatinine levels occurred in any of dogs. In all dogs with the dose of 1.5 ml/kg iohexol-ethanol mixture, the renal arteries were not embolized. All dogs with the dose of 3.0 ml/kg died. In all dogs with the dose of 2.10 ml/kg, the treated arteries were completely occluded. In barium-ethanol mixture administered group, the renal artery in one dog with the dose of 0.2 ml/kg was not embolized. In all dogs with the dose of 0.8 ml/kg, the renal arteries were completely embolized, but loac overembolization occured in two dogs. All animals with the dose of 0.4 ml/kg had effective embolization and no evidence of radiopaque barium opacity in systemic arteries distal to the renal-artery was found. All embolized kidneys were shrunk and decreased in size in gross examination and were shown diffuse necrosis in histopathologic examination. In the present study, renal arteries were embolized with the dose of 2.0 ml/kg iohexol-ethanol mixture or 0.4 ml/kg barium-ethanol mixture. And it is considered that the dose had a satisfactory embolic effect.
