Objectives : To explore the factors influencing antibiotics prescription by primary health physicians for acute upper respiratory infections(URI). Methods : We performed a survey of 370 primary health physicians randomly sampled in April, 2003. The questionnaire consisted of a prescription on the scenario of acute bronchitis case, along with opinions and reasons for prescribing antibiotics on URI. Results : We found that 54.7% of the physicians prescribed antibiotics on the example case of acute bronchitis which is known as not needing antibiotics. Female physicians and ENT physicians had a greater tendency to prescribe antibiotics. The factors influencing antibiotics prescription on URI were the belief about the effectiveness of antibiotics, preference for their own experiences rather than clinical guidelines, perception of patients' expectations, and perception of competitive environment. The prescription of antibiotics in the example case was affected by how much they usually prescribe antibiotics (OR=2.400, 95% CI=1.470-3.917) and the physicians who thought that antibiotics were helpful for their income prescribed antibiotics more than others (OR=6.773, 95% CI=1.816-25.254). Conclusion : These findings demonstrated that the false belief on the effectiveness of antibiotics, patient's expectation of medication and fast relief of symptoms, and perception of competitive environment all affected the physicians prescription of antibiotics on URI. It may help to find barriers to accommodate scientific evidence and clinical guidelines among physicians and to specify subgroups for education about appropriate prescription behaviors.

Real estate market has rapidly grown by active use of project financing in the early 2000s. However, many projects have been in trouble due to global economic recession after that period. It is mainly because those projects were pushed forward a business without comprehensive business feasibility analysis. This paper investigated current evaluation system for real estate development projects and then introduced new evaluation system including evaluation factor and criteria for real estate development projects to prevent implementation of the project without business value and to be able to evaluate potential projects in objective manner. This new evaluation system for real estate development projects can be applied to any type of real estate development projects by modifying evaluation items and weighting factor in accordance with the type and characteristics of project. Through the new evaluation system, the evaluation process for real estate development projects will be able to be standardized, be consistent, and the results of evaluation can be accumulated in consistent way.

An intact male, 3-year old, Sapsari, weighing 29 kg with a history of respiratory distress, anorexia, abdominal distension, and depression for 1 day was referred. Radiographic findings included a C-shaped soft tissue mass in the mid-abdominal cavity and loss of serosal detail. Ultrasonographs showed splenomegaly with hypoechoic coarse parenchyma, loss of venous flow in the dilated splenic veins, and thrombi. Based on image findings, acute isolated splenic torsion was diagnosed. Splenectomy and prophylactic gastropexy was performed. Another case was a spayed female, 8-year old, Shih-tzu, weighing 3.7 kg with a history of intermittent abdominal pain and a palpable abdominal mass for 1 year. Radiographic findings showed splenomegaly characterized by a soft tissue round mass. Ultrasonographs revealed displaced splenic hilum and absence of venous flow in the dilated splenic vein. Chronic isolated splenic torsion was diagnosed and also splenectomy and gastropexy was performed. Two dogs were recovered normally after surgery without any complications. Acute form of isolated splenic torsion showed acute systemic clinical signs, severe C-shaped splenomegaly on radiographs, and loss of all of splenic venous flow, perivenous hyperechoic triangle sign, and thrombi on ultrasonographs. Chronic form of isolated splenic torsion showed chronic obscure clinical signs, moderate splenomegaly on radiographs, and partial loss of splenic venous flow on ultrasonographs.

Objective : This study was undertaken to determine if Plantaginis Semen herbal acupuncture(PSA) has a protective effect on glycerol-induced acute renal failure in rats. Methods : Rats were dehydrated for 24hr and then injected with 4 ml/kg of 50% glycerol in each hindlimb muscle. In experiments for PSA effect, rats were received 0.1 ml of PSA extraction in both sides of corresponding $Sh\grave{e}nsh\bar{u}(BL_{23})$ of human body for 3 days after injection of glycerol. The experimental group were divided into the normal group, the control group, the sample 1,2,3 group. Results : Glycerol injection decreased glomerular filtration rate and increased urine volume, serum creatinine, BUN level and fractional excretion of $Na^+,\;K^+\;and\;Cl^-$. These results show that glycerol injection bring about acute renal failure. PSA significantly increased glomerular filtration rate and significantly decreased serum creatinine, BUN level and fractional excretion of $Na^+,\;and\;Cl^-$ as compared with control group. Conclusion : These results suggest that PSA can be used in prevention and treatment for acute renal failure. However, the precise mechanisms of PSA protection remain to be determined.

Objective : This study was undertaken to determine if Juglandis Semen herbal acupuncture(Ja) has a protective effect against glycerol-induced acute renal failure in rats. Methods : Rats were dehydrated for 24hr and then injected with 5 ml/kg of 50 % glycerol, one-half of dose in each hindlimb muscle. In experiments for Ja effect, rats received 0.1 ml of Ja extraction in both sides of corresponding $Sh\grave{e}nsh\bar{u}(BL_{23})$ of human body and non-acupuncture points(the root of tail) for 3 days after injection of glycerol. The experimental group were divided into the Normal group, the Control group, the Ja to $Sh\grave{e}nsh\bar{u}(BL_{23})$ group(Ja-AS), the Ja to non-acupuncture points group(Ja-AN). Results : There were significant decrease of urine volume, BUN, fractional glucose excretion, fractional phosphate excretion, total protein level in Ja-AS as compared with the control group. Conclusion : This suggests that Ja-AS could be used in prevention and treatment of acute renal failure. However, the precise mechanisms of Ja protection remain to be determined.

Objectives ; This study was undertaken to determine if Salviae Radix herb-acupuncture (SRA) exerts protective effect against alterations in membrane transport function in rabbits with mercury chloride (Hg)-induced acute renal failure. Methods and Results ; The administration of Hg at a subcutaneous single dose of 10mg/kg caused a reduction in GFR to 9.4% of the basal value and an increase in fractional Na+ excretion to 10-fold, indicating generation of acute renal failure. When animals were acupunctured with $0.5m{\ell}$ of SRA extract (0.1%) in both sides of Shinsu(BL23) for 7 days prod to Hg administration, such changes were significantly attenuated. The fractional excretion of glucose and phosphate was increased to approximately 132-fold and 7-fold, respectively, in rabbits treated with Hg alone, but the fractional excretion of glucose was increased to 26-fold and that of phosphate was not different from the basal value in SRA-pretreated rabbits. Uptakes of glucose and phosphate in purified isolated brush-border membrane and $Na^+-K^+$-ATPase activity in microsomal fraction were inhibited in rabbits treated with Hg alone, suggesting that impairment in proximal reabsorption of glucose and phosphate is resulted from a direct damage of membrane transport carriers and disruption of the normal $Na^+$ gradient. Conclusions ; Such changes were prevented by SRA. Uptakes of organic ions, PAH and TEA, in renal cortical slices were inhibited by the administration of Hg, which was prevented by SRA. Pretreatment of an antioxidant DPPD attenuated the increase in the fractional excretion of glucose and phosphate induced by the administration of Hg.

This study was designed to investigate the association between the period of engraftment and the nutritional status of patient s undergoing bone marrow transplantation for acute myelogenous leukemia (AML). Nutritional status was evaluated by body mass index (BMI), percentage of ideal body weight (PIBW), percentage of weight loss, and serum albumin, total protein (T protein), hemoglobin (HGB) and hematocrit (HCT) levels on the day prior to transplantation and on the day of bone marrow transplantation. The periods of engraftment were determined by absolute neutrophil counts (ANC) above $500/mm^3$ from the day of bone marrow transplantation. The study subjects were 80 patients (55 males, 25 females) with acute myelogenous leukemia admitted to the University Hospital in Seoul. The result of this study is as follows : Tie nutritional status values of the majority of patients on the day prior to transplantation were in the normal range except for HGB and HCT ; however, during hospitalization, all of the levels of the nutritional status values were significantly decreased. The periods of engraftment of the abnormal group according to their BMI, PIBW, HGB and HCT levels on the day of bone marrow transplantation showed no difference when compared to the normal group. However, the periods of engraftment of the abnormal group, according to the percentage of weight loss, albumin, and T protein levels were significantly decreased when compared to the normal group. Therefore, the nutritional status of patients at the time of transplant had a noticeable influence on the periods of engraftment. Our results suggested that nutritional status is a critical factor of engraftment in BMT during pre-transplant and post-transplant. Futhermore, we recommend that the process of nutritional preparation for the transplant should initiate immediately after the transplant decision has been made.

Malaria is one of the most common infectious diseases in the world. Plasmodium falciparum, accounting for nearly all malaria mortality, kills an estimated 1 to 2 million persons yearly and has several features that make it deadlist of malarias. While cerebral malaria is the most common presentation of severe disease, acute lung injury associated with malaria is uncommon but serious and fatal complication. We report two cases of severe malaria with ARDS and multi-organ failure. All two patients traveled to foreign countries, Kenya, Papua New Guinea where choroquine-resistant malaria is distributed. The first case, which developed cerebral malaria, hypoglycemia, multi-organ failure, and ARDS, treated with quinine and mechanical ventilator, but expired due to oxygenation failure. Autopsy showed acute necrotizing infiltration, diffuse eosinophilic fibrinoid deposits along the alveolar space, and alveolar macrophage with malaria pigment The second case also developed multi-organ failure, followed by ARDS, and was treated with quinine, exchange transfusion, plasmapheresis, and mechanical ventilator. He recovered with residual restrictive lung change after treatment.

Small bowel malignancy consists 1~2 % of overall gastrointestinal tract cancer and leiomyosarcomas of small intestine are 10~20% of small bowel malignancy. Small bowel leiomyosarcomas are rare in incidence and have no specific symptoms, signs or definite radiologic findings, so it is not easy to diagnose at early stage of disease. They are found occasionally by unknown origined gastrointestinal bleeding, abdominal pain, intestinal obstruction, perforation and palpable mass, and diagnosed mostly by operation. Recently annual case reports are increasing trend in Korea. We experienced two cases of small bowel leiomyosarcoma which was diagnosed finally by pathologic findings, so we report them With literatural review.

The Northeast Asia has been the fastest growing region in the world for the past few decades. And now the economic bloc maintains its status as a major powerhouse of the world economy. On the way of its economic growth, Russia and Central Asian countries have emerged as major trading partners. The Trans-Siberian Railway(TSR) has been playing a pivotal role in promoting economic cooperation between the two regions. This paper investigates economic environment of the Korean TSR service operators through the SWOT analysis, then proposes management strategies for them. For this purpose, the authors analyze characteristics and roles of the TSR service operators. In addition, a comparison of difference between service operators and shippers about their recognition of economic environment of the TSR transportation service is also carried out.
