  • A 12-year-old spayed female mixed-bred dog presented with nasal bleeding of 2 days duration and a skin nodule in the left flank. No abnormalities were found in coagulation profiles and blood pressure. Cytological evaluation of the nodule revealed numerous characteristic round organisms having a nucleus and a bar within macrophages and in the background, consistent with leishmaniasis. In vitro culture was unsuccessful but PCR of the nodular aspirate identified the organisms as Leishmania infantum, and the final diagnosis was canine leishmaniasis. No history of travel to endemic countries was noted. Because the dog had received a blood transfusion 2 years before the illness, serological screening tests were performed in all donor dogs of the commercial blood bank using the commercial Leishmania ELISA test kit, and there were no positive results. Additional 113 dogs with hyperglobulinemia from Seoul were also screened with the same kits but no positive results were obtained. To the best of the author's knowledge this is the first autochthonous case of canine leishmaniasis in Korea.

  • Background : It was not enough to apply three kinds of syndrome differentiation in our oriental medical textbook to tremor's treatment according to reports of Korea and traditional medical textbook of China. Objective : To investigate syndrome differentiations by types of diseases related to tremor through Chinese journals review and to suggest adding possible syndrome differentiations. Methods : Literature search was performed using China Academic Journal (CAJ), the search engine of China National Knowledge Infrastructure (CNKI) from January 1994 to December 2009. Searching key words were Chinese characters in combination meaning tremor, paralysis agitans, and syndrome differentiation. We included all types of articles that explained or referred to definite syndrome differentiations. The symptoms and oriental medications by syndrome differentiation in selected articles were extracted and summarized. Results : 56 Chinese journals were ultimately selected. 37 kinds of syndrome differentiations about tremor were investigated, which included dual deficiency of qi and blood (氣血兩虛) quoted 31 times, liver-kidney yin deficiency (肝腎陰虧) 23 times, liver-kidney deficiency (肝腎不足) 21 times, and phlegm-heat stirring wind (痰熱動風) 20 times. 37 kinds of syndrome differentiation could by group into eight types, such as liver-kidney yin deficiency (肝腎陰虧), dual deficiency of qi and blood (氣血兩虛), phlegm-heat stirring wind (痰熱動風), heart deficiency and spirit weakness (心虛神弱), blood stasis due to qi stagnation (氣滯血瘀), sea of marrow deficiency (髓海不足), liver qi depression (肝氣鬱結), and liver yang transforming into wind (肝陽化風). Conclusion : We suggest that the syndrome differentiations of tremor, such as heart deficiency and spirit weakness (心虛神弱), blood stasis due to qi stagnation (氣滯血瘀), sea of marrow deficiency (髓海不足), liver qi depression (肝氣鬱結), and liver yang transforming into wind (肝陽化風), can be added to liver-kidney deficiency (肝腎不足), dual deficiency of qi and blood (氣血兩虛), and phlegm-heat stirring wind (痰熱動風) of the textbook. Further systematic research will be needed on them.

  • Unilateral absence of the pulmonary artery (UAPA) is a rare congenital anomaly that occurs in association with other cardiovascular anomalies, such as tetralogy of Fallot or ventricular septal defects. On the other hand, it is less commonly found as an isolated finding without accompanying diseases. Isolated UAPA is a rare cause of hemoptysis, and massive hemoptysis has been reported to occur in approximately 18~20% of UAPA patients during their clinical course. Even if a lung resection is considered a treatment option to control life-threatening hemoptysis, the procedure is more difficult than an ordinary lung resection because of the excessive collateral vessels from the systemic circulation. We encountered an isolated UAPA occurring in a young male patient suffering from intermittent blood tinged sputum. To our knowledge, only a few cases of isolated UAPA have been reported in Korea. This case is expected to be a good example to help clinicians better understand isolated UAPA as an unusual cause of hemoptysis.

  • The objectives of this study are to evaluate the reliability of an existing nonlinear analysis program for predicting the inelastic behavior of reinforced concrete frame with seismic details and to observe the redistribution of the internal forces, which can not be easily measured by an experiment. In order to carry out this task, the nonlinear analysis program of IDARC 2D(3) was run on a 2-bay, 2-story moment-resisting reinforced concrete plane frame with seismic details. (1) The effort to obtain the results of the analysis similar to those of experiment was made by determining the appropriate values of model parameters. The comparison of the analysis results with those of experiment and the observation of the distribution of internal forces obtained through nonlinear analysis points to the following conclusions. (1) The overall relationship between lateral load and lateral displacement given by the analysis is similar to that of experiment. However, the values of initial stiffness and the amount of energy dissipation in the initial displacement steps given by the analysis show larger values than those of experiment. (2) The analysis provided detailed information on the distribution and redistribution of internal forces and proved useful in elucidating the crack pattern, the sequence of the occurrence of plastic hinges, and the failure or yielding mechanism for the whole structure. (3) In spite of the similarity in overall behavior of analysis and experiment, there exists a significant discrepancy in some local behaviors. Furthermore, the hysteresis in the relationship between moment and curvature in some column ends have shown sudden deteriorations in strength, which can not be interpreted satisfactorily at the present time. Therefore, it is necessary to develop a better analytical model to fill this knowledge gap.

  • Hematoma is quite a common complication of femoral arterial catheterization. However, to the best of our knowledge, there have been no previous studies regarding deep vein thrombosis (DVT) caused by compression of a vein due to a hematoma. We report a case of a hematoma developing after femoral arterial catheterization and causing extensive symptomatic DVT. A 59-year-old male was seen in our Emergency Department with right lower leg swelling 15 days after coronary stent implantation performed using right femoral artery access. Computed tomographic (CT) scanning revealed a large hematoma (45 mm in its longest diameter) compressing the common femoral vein and with DVT from the right external iliac vein to the popliteal vein. Due to the extensive DVT involvement, we decided to release the compressed common femoral vein by surgical evacuation of the large hematoma. However, even following evacuation of the hematoma, as the DVT did not resolve soon, further mechanical thrombectomy and catheter-directed thrombolysis were performed. Angiography then showed nearly resolved DVT, and the leg swelling was improved. The patient was discharged with the anticoagulation medication, warfarin.

  • A 3 years-old female mixed dog (weighing 5.3 kg) was referred to veterinary teaching hospital of Kangwon National University with primary complaints of syncope, severe exercise intolerance, depression and lethargy. Diagnostic studies revealed polycythemia, right sided cardiac enlargement on thoracic radiography and right-to left atrial septal defect, severe pulmonary stenosis (~5 m/s of peak velocity) and right ventricular hypertrophy. Based on diagnostic findings, the dog was diagnosed as trilogy of Fallot. To improve clinical condition of this dog, diltiazem and enalapril were prescribed with weekly phlebotomy. To author's best knowledge, this is the first case of trilogy of Fallot in Korea.

  • Pump sump system or pumping stations are built to draw water from a source such as river and used for irrigation, thermal power plants etc. If pump sump is improperly shaped or sized, air entraining vortices or submerged vortices may develop. This may greatly affect pump operation if vortices grow to an appreciable extent. Moreover, the noise and vibration of the pump can be increased by the remaining of vortices in the pump flow passage. Therefore, the vortices in the pump flow passage have to be reduced for a good performance of pump sump station. In this study, the effect of pump intake leaning angle and flow rate on the pump sump internal flow has been investigated. There are three cases with different leaning angle. Moreover, a pipe type with elbow also has been studied. The flow rate with three classes of air entraining vortices has been examined and investigated by decreasing the water level. The result shows that the air entraining vortices easily occurs at the pump intake with large leaning angle. Moreover, the elbow type of the pump intake easily occurs air entraining vortices at the high flow rate (or velocity) in comparison to other pump intake type.

  • This study aims to develop an instrument for measuring high school students' action competence on climate change (ACoCC). The instrument is defined as the construct comprised of seven factors and thirty-five items and takes approximately 15 minutes to fill out. A panel of experts and students' content validation were undertaken to modify the items. Five hundred and twenty-eight first and second graders in Korean high schools participated in the instrument survey. To assess the reliability and validity of ACoCC instrument, item analysis (mean, skewness, kurtosis, item-total correlation), internal consistency estimate, and confirmatory factor analysis were used. It was appropriate to use the 7-dimensional ACoCC instrument (knowledge about climate change, climate change sensibility, reflection, communication, integrated thinking, willingness, decision making), with 35 items for high school students. The following instrument was self-report given in the 5-point Likert scale (1=strongly disagree, 2=disagree, 3=neutral, 4=agree, 5=strongly agree). The internal consistency coefficient was shown as a whole was shown as 0.953, and the subscale's internal consistency coefficient ranged from 0.786 to 0.862.

  • Objective: The purpose of this study was to investigate the effect of electroacupuncture on acute pancreatitis (AP). Method: The search engines that were used included PubMed, CNKI, OASIS, NDSL, the Korean Traditional Knowledge Portal, and J-STAGE. The search period was from the creation of the search engine to May 6, 2019; there were no language limitations. Extractions and selections from the literation were made by two authors. The study included randomized controlled trials with electroacupuncture for patients with acute pancreatitis. Cochrane's risk of bias (RoB) was used as the methodological quality assessment scale. Results: Nine studies were finally selected. It was observed that using electroacupuncture with general Western medicine treatment for AP was more effective than using only general Western medicine treatment. Although most of the studies showed a high risk of bias, there were significant differences among the indicators. Conclusion: The electroacupuncture treatment with Western medicine may be more effective in reducing symptoms of AP than Western medicine alone. However, due to the limitations of the research design, it was not enough to obtain reliable information. As a result, high quality research will be additionally required.

  • This study explored the internal world through sandplay therapy for an elementary school boy who had social and emotional difficulties of poor peer relations, anxiety and withdrawal. This study examined the changing processes of sandboxes, how a boy expressed his internal world by the content themes in sandplay according to Turner (2009) based on analytical psychology and sandplay theories. There were 72 sessions. The initial phase was 1-6 (The beginning of war) expressing confusing wars as the start of a long internal journey. The intermediate phase was 7-55 (Struggle), dividing by phase I 7-18 (Hero's fight I), phase II 19-36 (Hero's fight II), phase III 37-48 (Seeking for a male identity), and phase IV 49-55 (Centering). The client identified himself as a teenaged hero and expressed the conflict between good and bad, between death and rebirth and struggled for seeking treasures in the fight of heroes. He found identity as a male by finding a sense of existence, establishing order in the middle of confusion, and expressing strong and rational masculinity. The final phase was 56-72 (The winner of the struggle). In the fights repeating, he expressed an adventurous and positive male energy such as racing, speed contests and a union in the opposites of hero and heroine as well as the birth of a new conscious. This study provides a basic knowledge of educational guidance in school and counseling fields by expanding the understanding of a boy's unconsciousness.
