Hemodialysis is an effective therapy for renal failure in veterinary practice. To evaluate hematologic and hemodynamic changes during hemodialysis, 13 dogs were treated with hemodialysis, after which complete blood cell counts (CBC), serum chemistry, and mean systolic blood pressure were analyzed. For CBC, white blood cells (WBC) and platelets underwent significant changes. In serum chemistry, there were significant differences in blood urea nitrogen (BUN), creatinine, total protein, albumin, globulin, amylase, calcium, potassium, and phosphorus contents. Further, mean systolic blood pressure suddenly increased in early hemodialysis and decreased significantly thereafter. During hemodialysis, adverse effects were observed in some dogs as follows: bleeding (1 dog), anemia (2 dogs), leukopenia (8 dogs), thrombocytopenia (2 dogs), and hypotension (1 dog). This study demonstrates hematologic and hemodynamic effects during hemodialysis as well as complications similar to human medicine. Before applying the commercialized human hemodialysis system to canine renal failure patients, we monitored hematologic and hemodynamic findings during hemodialysis in healthy beagle dogs.

Low level laser therapy (LLLT) has facilitated an improvement in acupuncture treatment. In this study, we stimulated Shaochong (HT9), Dadun (LR1), Shaohai (HT3), and Yingu (KI10) acupoints with pulsed laser diodes 532 nm [green laser] and 658 nm [red laser] in rats with induced middle cerebral artery occlusion(MCAO). The animals were divided into 6 groups: intact control; MCAO control without LLLT; LLLT with red laser at HT9·LR1 and HT3·KI10 (RR); LLLT with green laser at HT9·LR1 and HT3·KI10 (GG); LLLT with green laser at HT9·LR1 and red laser at HT3·KI10 (GR); and LLLT with red laser at HT9·LR1 and green laser at HT3·KI10 (RG). We evaluated the immunohistochemical changes in the hippocampal CA1 region, and complete blood count changes. Compared to the MCAO control group, the RG group showed a significant decrease in Bax and cytochrome c levels in the hippocampus, and a significant increase in hemoglobin level, hematocrit, total white blood cell, neutrophil, lymphocyte, monocyte, and erythrocyte counts.

Thanks to the rapid growth of smart phone distribution rate, the consumers are using different shopping channels at once or aim an optimum shopping experience through on-time channel changes. However, the current multi or cross channels have limits to satisfy the consumers becoming ‘smarter’ everytime so it is essential the appearance and application of omni-channel which is more suitable in the current shopping environment. Although the omni-channel commerce throughout the world is just in its initiatives, Asian countries are not very active in introduction or development of omni-channel related services and it lacks the research on this field compared to the Occident. Therefore, this study investigated the relationship among perceived value, satisfaction and shopping channel switching intention of consumers to promote the omni-channel activation plan.

We report a case of lymphocutaneous sporotrichosis in a 76-year-old female successfully treated with oral fluconazole. This case had showed almost complete clinical resolution by 200mg daily administration of oral fluconazole for 7 weeks and has got no relapse until 18 weeks after the completion of the treatment. We would emphasize good therapeutic effects of fluconazole such as more rapid therapeutic response than the previous reports and no observable side effects. [Kor J Med Mycol 4(2): 148-152]

Objectives : We report an interim result of conformal radiotherapy in a patient with early stage cancer at the base of the tongue, which developed in a previously irradiated area. Materials and Methods : A 64-year-old male patient was diagnosed with T4NOMO supraglottic cancer. He received 72Gy of radiation therapy from 21 November 1988 to 24 February 1989. He had local failure and underwent a salvage total laryngectomy on 28 August 1989. Subsequently, he did well. In early 1999, he suffered from throat pain. He had a 2.5cm ulcerative mass at the base of his tongue, in the area that had been irradiated previously. Biopsy showed squamous cell carcinoma. After workup, he was diagnosed with base of tongue cancer with T2NOMO. Surgery was not feasible because the morbidity was not acceptable. Since it was difficult to re-irradiate the area with a curable dose using conventional 2D radiation therapy with an acceptable morbidity, we decided to try conformal radiotherapy. We used 7 static beam ports with field sizes from 7×6.4 to 8×8㎠, using 6 and 10MV photons. The fractionation regimen was 1.8Gy, 5 times per week. He received 64.8Gy in 36 fractions from 9 April 1999 to 1 June 1999. Results : In the 21 months since radiotherapy, the patient has not experienced any acute or chronic complications, such as xerostomia. He experienced relief of pain shortly after the start of radiotherapy, showed a complete response, and is still doing well. Conclusion : Conformal radiotherapy can be used to treat cancer that develops within a previously irradiated field, with curative intent.

Numerical simulation is performed by the commercial code FLUENT for individual air condition system to calculate the velocity and temperature profiles around worker in climate room. The main calculation region is the space of ㄱ shape between wall and worker in the individual air condition system. The fresh air is emitted from 3 inlet attached on the right, left and center wall. Because the comfort of worker is closely related with the velocity and temperature of wind, these data are key role for design of the individual air condition system. This work is previous study for evaluation of thermal comfort of workers in room without much experiments according to metabolism and heat emission of human body. Numerical simulation results are as followings, 1. There is an possibility of the thermal comfort of worker is gotten worse due to the presence of dramatic change of wind velocity around worker. 2. Temperature gap exists in worker's body between top and bottom according to fresh air inlet velocity and position which is right, left and center of wall. 3. Calculation results of the skin temperature of worker are key data for evaluation of thermal comfort with experimental data in climate room. 4. Optimum condition of temperature, direction and velocity of fresh air will be obtain by numerical simulation for energy effective individual air condition system.

쌀 생산비를 줄이고 대경지 규모화 영농에 적응할 수 있는 농기계 개발을 목적으로 연구개발한 대규모 경지적응 트랙터 부착 대형벼이앙기의 구성과 특징 및 개발시작기의 재배적 실용성 평가결과를 요약정리하면 다음과 같다. 1. 트랙터 부착 12조 대형벼이앙기는 크게 바퀴자국 제거로타리, 문짝형 정지판, 이앙장치부 등으로 구성되어 있다. 2. 트랙터 부착 12조 이앙기는 트랙터 동력을 이용하여 로타리, 정지 및 이앙작업이 동시에 이루어 질 수 있도록 개발하였다. 3. 바퀴자국을 없애는 날은 기존의 로타리 날을 교체하면 되도록 반달형 날로 제작하였다. 4. 이앙기는 이동시는 접을 수 있도록 설계 제작되어 대형화가 가능하므로 기존 6조 승용이앙기에 비하여 이앙작업 능력이 1.5배 이상이었다. 5. 트랙터 부착 대형벼이앙기는 트랙터와 같은 큰 동력원을 이용할 수 있으므로 측조시비기, 긴매트모 탑재 등 다양한 작업기 및 기능을 추가로 부착 가능하도록 설계되었다. 6. 트랙터 부착 대형벼이앙기는 어린모 및 중묘이앙시 결주율은 3.0∼4.3%로 기계이앙기 결주 허용범위 5% 미만이었다. 하지만 무경운 논에서는 이앙작업은 가능하나 부묘율이 다소 높은 점은 보완이 필요하다. To develop a labor saving rice cultivation technology, a new tractor attached rice transplanter has been developed for large scale farming and its field performance was evaluated. The rice transplanter consists of three major parts such as rotary for removing tractor tire furrow, door-shaped soil leveling plate and transplanting equipment. The rice transplanter is operated using the power of the tractor and performs rotary, harrow and seedling transplanting simultaneously. A half moon shaped rotary blade was found to be very efficient to remove tire furrow developed during seedling transplanting and the original rotary blade can be replaced easily with existed rotary blade. The seedling transplanting part of the transplanter was designed to fold into small size and the transplanting efficiency of the transplanter was found to be 1.5 times higher than that of the conventional riding type six row transplanter. Since the transplanter is operated through a strong power of the tractor, the additional attachment such as fertilizer application apparatus and long mat rice seedling carrier is possible. Based on the field performance of the transplanter, although the missing hill percentage showed roughly with 3.0∼4.3% for 10-day and 30-day old seedlings but the percentage is less than 5% which is maximum missing hill permit in the transplanting rice. Seedling transplanting in no-tillage field condition is acceptable but floating seedling percentage is still high and thus further technology improvement for minimizing floating seedling percontage is needed.

The purpose of this study is to investigate the variation of pore size distribution of the coal-based extruded activated carbon. The extruded activated carbon was prepared by extruding the mixture of coal powder and coal tar. Pore size distribution of the extruded activated carbon was compared with that of the extruded coal and the extruded char. Also it was compared with that of the crushed activated carbon, raw coal and char. The extruded coal had coarser surface than that of raw coal. Macropores of the extruded coal were funned near 10,000Å in diameter during carbonization process and steam penetrated easily between particles and were growing between 3,000Å and 20,000Å in diameter during activation process.
