A sarcoidosis is a multisystemic granulomatous disorder that has a predilection for pulmonary involvement, and the common radiological findings for the disease are bilateral nodular or reticulonodular patterns. Pseudoalveolar sarcoidosis is a rare presentation of sarcoidosis. The radiological finding is an alveolar pattern that involves or compresses the alveoli by clustered interstitial granuloma. A 58-year-old man was admitted due to incidental findings of a unilateral consolidative lesion as seen on chest radiography. A chest computed tomography (CT) examination showed multiple bronchoalveolar consolidations that were suspicious of a malignancy. However, a percutaneous needle biopsy revealed non-caseating granuloma with an asteroid body that was compatible with sarcoidosis. After one month, the consolidative lesions improved without any treatment.

This paper examines the characteristics of structural change in the international agro-food trade network with a global trend of the FTA diffusion. By focusing on the centralities and the community structure to identify the agro-food trade network, we use the social network analysis and the trade data contained of 07, 08, 20, and 21 at the 2-digit HS product level among 45 countries over the last 15 years. The main analytical results are as follows: 1) Not only has intra trade network intensified more than inter-regional trade, but also, there is no doubt that inter-regioanl trade by linking has steadily increased. 2) EU countires have the high indices of centrality, which have already been highly integrated. 3) Intraregional agro-food trade network for fresh vegetables and processed food sector in Asia is shown to be strongly integrated. This finding suggests that the processes of economic integration will help strengthen the trade network for agro-food in a culturally homogeneous region. 4) The case of Korea's participation in the RCEP and TPP, Korea's power in the agro-food network tends to be reinforced, especially in the processed food sector. Overall, there is a need for establishment of spatial strategies and policies across the different regions for Mega FTAs.

Most researches about residential improvement projects deal with different process phase in order to examine important affecting variables. The main purpose of this study is to identify influential change of locational variables according to the process of residential improvement projects. Generally the residential improvement project consists of four phases such as site designation, project committee approval, residents association establishment and final project approval. The discriminant and correlation analyses are employed to examine the changes of locational variables by each phase of the project process. In residential redevelopment projects, the finding shows that locational variables in the final project approval phase act differently from those in the other phases. On the other hand, the variables act similarly among the four phases in the case of residental rebuilding projects although the significant level of discriminant analysis result, in the site destination phase, is relatively low significance. Therefore, there is no difference among the project process phase to examine to what extent of the residential improvement projects.

In this study, the effects of the leakage flow between the baffle and tube bundles on the performance of a shell and tube heat exchanger (STHE) were examined using the commercial software ANSYS FLUENT v.14. A computational fluid dynamics model was developed for a small STHE with five different cases for the ratio of the leakage cross-sectional area to the baffle cross-sectional area, ranging from 0 to 40%, in order to determine the optimum leakage flow corresponding to the maximum outlet temperature. Using fixed tube wall and inlet temperatures for the shell side of the STHE, the flow and temperature fields were calculated by increasing the Reynolds number from 4952 to 14858. The present results showed that the outlet temperature, pressure drop, and heat transfer coefficient were strongly affected by the leakage flow, as well as the Reynolds number. In contrast with a previous researcher's finding that the leakage flow led to simultaneous decreases in the pressure drop and heat transfer rate, the present study found that the pertinent leakage flow provided momentum in the recirculation zone near the baffle plate and thus led to the maximum outlet temperature, a small pressure drop, and the highest heat transfer rate. The optimum leakage flow was shown in the case with a ratio of 20% among the five different cases.

Slopes are commonly formed both above and below roads located in mountainous terrain and along riversides. The Buk-sil site, a cut slope formed below the road, collapsed in October, 2010. A field investigation determined the causes of failure as improper drainage of valley water from the slope above the road and direct seepage of road-surface water. These factors may have accelerated the collapse via complex interaction between water and sub-surface structures such as bedding. Projection analysis of the site showed the possible involvement of plane, wedge, and toppling failure. Safety factors calculated by Limit Equilibrium Analysis for plane and wedge failure were below the standard for wet conditions. The wetness index, analyzed using topographic factors of the study area, was 9.0-10.5, which is high compared with the values calculated for nearby areas. This finding indicates a high concentration of water flow. We consider that water-flow control on the upper road is crucial for enhancing slope stability at the Buk-sil site.

This study investigated the effects of 'K-POP' preference on purchase intention of Korean products. Especially, it revealed the mediating role between the participation intention of Korean culture event and the purchase intention of Korean products. Further, we examined the difference in the path relation according to the use-behavior of Korean wave contents. In this proposed model, we can see 'K-POP' preference had a positive effect on participation intention of Korean culture event, but it was not significant for purchase intention of common products. The participation in Korean culture event had significant effects on the purchase intention of Korean culture products and the purchase intention of common products. However, the purchase intention of Korean culture products had no significant effects on the purchase intention of common products. Thus, our finding showed that higher preference of 'K-POP' did not make cause purchase intention of common products. Further, the higher the preference of 'K-POP' was, the higher the participation intension of Korean culture event was and, as a result, the purchase intention of common products got higher. In addition, path analysis results according to the media usage behaviors show that Chinese consumer who uses the internet and has a higher preference of 'K-POP' had a positive effect on the purchase intention of common products. Furthermore, it has a positive effect on both purchase intension of Korean culture products and purchase intension of common products. In case of Chinese consumer who use the television, radio and newspapers, K-POP preference had no significant effect on the purchase intension of common products.

This paper is aimed at finding out the clue to the medical solution to the pathological phenomena of the dehumanizing and demoralizing state of our society by centering around the Chiljeong that originates from Oriental Medicine, Sung Confucianism and Sa-sang Medicine(四象醫學). In these fields,the Chiljeong is based on the theory of Eum-yang and Viscera(陰陽.臟腑論) in Oriental Medicine, on the problems of good and evil in Sung Cunfucianism and on the theory of Sa-sang Visceral Localization(四象.臟局의 理論) in Sa-sang Medicine. The principles of geneation of Chiljeong : In case of Oriental Medicine, Sin(神) controls Chiljeong and of it is stored in five Viscera, it becomes Sin in the Heart, Hon(魂) in the Liver, Sa(思) in the Spleen, Bed-Woo(悲.憂) in the Lung, and Kyeong-Kong(驚.恐) in the Kidney. Then five Viscera react with outer stimuli or Sin, it gives off Chiljeong as Joy(from the Heart), Anger(from the Liver). Thought (from the Spleen), Anxiety and Sorrow(from the Lung) and Surprise and Fear(from the Kidney) In Sung Confucianism, Sim(心) comtrols Seong-jeong(性.情), and at the moment of that Sim gives off Jeong(情), it becomes good when the Li(理) gibes off itself and then Chi(氣) follows Li, or Chi gives off itself and is regulated optimally, out it becomes evil when Li cannot preside over Chi and then shaded by cloudy Chi. The pathology: If the Chiljeong exceeds one's capacity, the corresponding Vicsera will be damaged, and the Passions(喜.怒.哀.樂) that may harm to four types of constitution severly are the Joy and Pleasure(in Tae-eum-in 太陰人 and So-eum-in 少陰人) and Grief and Anger(in Tae-yang-in 太陽人 and So-yang-in 少陽人), so one should be alert on some passions by regrding his constitutional frailty. More over, because of the variations in Sa-sang Visceral Localyzatin there is various ability in human affairs, but as the clumsiness in human affairs may make him hurt by it, so one should be prevented from these passions and human affairs, that is flowing Joy and Participations(黨與) in Tae-yang-in, flowing Pleasure and Dwelings(居處) in So-yang-in, explosive Anger and Companies(交遇) in So-eum-in, explosive Grief and Affairs(事務) in Tae-eum-in. How to clutivate the human nature: The ulitmate purpose in Oriental Medicine is preserving Cheon-Jin(天眞), that is following the Tao(道) by making him be in harmony with the Chi(氣) of the Seasons and by living a simple life. In Sung Confucianism, the way preventing the lustful desire and preserving Cheon-li(天理) is to observate derectly the calm, original place of human nature with reverence, when Sim has nat given off itself yet, and when Sim has already given off, it also is to meditating on one's passion and thought that the principle of good should be researched on or the evil should be cut off according to it's being good or evil. Such like as these various aspects of research on the Chiljeong it will be helpful in understanding human nature by producing the various materials on it, moreover, by doing so, we can lead out appropriate solution on the confusions of judgement value and demoralization.

Two Maltese (2-year-old, intact female and 4-month-old, intact female) and a Pekingese (10-year-old, intact male) dogs were referred due to vomiting, anorexia, head-pressing and hypersalivation. Physical examinations, complete blood count, serum chemical analysis, radiography, ultrasonography and computed tomography (CT) were evaluated. Laboratory findings in these dogs included high hepatic enzyme, serum bile acid and ammonia concentration. Microhepatia was found on abdominal radiographs in two dogs. The existence of portosystemic shunt was presented in abdominal ultrasonography. The shunt vessel was identified in all dogs by CT imaging. Based on three-dimensional CT reconstruction, the origin and termination of each shunt vessel were defined certainly. In consequence, each dog was diagnosed single extrahepatic portosystemic shunt. After diagnosis, surgical treatment was performed in all dogs. This case report describes clinical finding, imaging characteristics, and three-dimensional CT imaging of single extrahepatic portosystemic shunt cases.

5 year-old female Siberian husky which was 27 kg had presented with a recurrent rhinitis with chronic discharge and cough. A nasal foreign material had been suggested by a finding of a bone density ($0.3{\times}0.3$ cm) in the left nasal cavity on X-ray and CT-scanning. Soft tissue opacity in frontal sinus and nasal cavity was increased and foreign material was located beside turbinate bone in the left nasal. We found that there was the increase in the number of eosinophil and mast cell by the nasal cytology test. These results mentioned above indicated that the rhinitis by nasal foreign body was suspicious. We decided that the transfrontal rhinotomy could be the proper procedure to approach the material in this case. After rhinotomy, the foreign body and severe sticky discharge were removed. Drain was placed through the hole and into the frontal sinus and nasal cavity which were flushed two times a day for 7 days. The clinical signs such as cough and nasal discharge were shown to be improved in the every visiting for the re-check. On the $40^{th}$ day after surgery, we could confirm that the most of soft tissue density in the frontal sinus and nasal cavity was decreased by CT-scanning. However, foreign body was not identified by histological examination. For the treatment of chronic rhinitis caused by foreign body, the surgical method such as rhinotomy can be applied, when it is difficult to remove it in the guide of the nasal endoscope.

In electronic catalogs, each item is represented as an independent unit while the parts of the item can be composed of a higher level of functionality. Thus, the search for this kind of product database is limited to the retrieval of most similar standard commodities. However, many industrial products need to configure optional parts to fulfill the required specifications. Since there are many paths in finding the required specifications, we need to develop a search system via the configuration process. In this system, we adopt a two-phased approach. The first phase finds the most similar template, and the second phase adjusts the template specifications toward the required set of specifications by the Constraint and Rule Satisfaction Problem approach. There is no guarantee that the most similar template can find the most desirable configuration. The search system needs backtracking capability, so the search can stop at a satisfied local optimal satisfaction. This framework is applied to the configuration of computers and peripherals. Template-based reasoning is basically the same as case-based reasoning. The required set of specifications is represented by a list of criteria, and matched with the product specifications to find the closest ones. To measure the distance, we develop a thesaurus of values, which can identify the meaning of numbers, symbols, and words. With this configuration, the performance of the search by configuration algorithm is evaluated in terms of feasibility and admissibility.
