Administration of autologous mesenchymal stem cells (MSCs) has been shown to improve renal function and histological findings in acute kidney injury (AKI) models. However, its effects in chronic kidney disease (CKD) are unclear, particularly in the clinical setting. Here, we report our experience with a CKD patient who was treated by intravenous infusion of autologous MSCs derived from adipose tissue in an unknown clinic outside of Korea. The renal function of the patient had been stable for several years before MSC administration. One week after the autologous MSC infusion, the preexisting renal insufficiency was rapidly aggravated without any other evidence of AKI. Hemodialysis was started 3 months after MSC administration. Renal biopsy findings at dialysis showed severe interstitial fibrosis and inflammatory cell infiltration, with a few cells expressing CD34 and CD117, 2 surface markers of stem cells. This case highlights the potential nephrotoxicity of autologous MSC therapy in CKD patients.

A cutaneous adverse drug reaction (CADR) refers to an unexpected skin and mucosal reaction caused by drug administration. In the present case, a 65-year-old male presented with generalized itching and a maculopapular rash after taking Western medication, including anticonvulsants and a nonsteroidal anti-inflammatory drug (NSAID). He was treated with Gamiseungmagalgeun-tang, a traditional Korean herbal medicine. After treatment, the patient's symptoms improved, without recurrence. Based on this experience, traditional Korean herbal medicine, including Gamiseungmagalgeun-tang, may be beneficial for improving symptoms of CADRs.

정부 산업정책의 전략적 지원단위인 벤처기업의 지속가능한 성장을 위해 해외진출의 중요성이 강조되는 경영환경 하에서, 본 연구는 벤처기업의 해외진출과 이에 따른 성과에 영향을 미치는 기업의 내부상황특성을 규명하고, 기업가정신과 해외진출동기 및 성과 간의 영향관계에 있어 내부상황특성의 영향력을 탐색하기 위한 목적으로 수행되었다. 이에 따라, 본 연구는 내부상황특성으로 기업업력, 조직규모, 해외경험 및 조직구조로 대변된 조직자원과 혁신성, 진취성, 위험감수성으로 구성된 기업가정신을 설정하였다. 2010 벤처기업 정밀실태조사 데이터를 활용하여 연구목적을 충족하는 기업을 층화표본추출한 후 설문조사를 실시하였으며, 개별기업으로부터 회수된 총 289개의 응답데이터를 다중회귀모델을 통해 분석하였다. 내부상황특성 중 기업업력과 조직규모는 기업가정신과 해외진출동기 간의 영향관계에는 조절효과가 확인되지 않았으나 진출성과 간의 영향관계에 있어 유의한 조절효과를 보여주었다. 해외경험과 조직구조는 해외진출동기 및 진출성과 모두에 대하여 기업가정신과 결합할 경우 유의한 조절효과가 형성되는 것으로 확인되었다. 이상의 결과는 조직의 상황특성과 기업가정신으로 대변되는 내부자원특성이 벤처기업의 해외진출결정에 분명한 영향관계를 가질 뿐만 아니라 지속적인 진출성과를 달성하는 데에 유효성을 갖고 있음을 의미하며, 내부상황특성과 기업가정신이 적절히 결합될 경우 효과적인 해외진출과 우수한 진출성과가 창출될 수 있음을 의미한다. 본 연구의 결론에서는 분석결과에 대한 해석을 포함하여, 벤처기업의 해외진출을 촉진시키기 위한 경영활동방향과 성과제고를 위한 정책적 시사점을 제시한다.

기관성 기관지는 기관분기부 상부의 기관에 이소성 기관지가 존재하는 기관지 기형으로 대부분 특별한 증상없이 기관지내시경검사 혹은 기관지조영술시에 우연히 발견되고 특별한 치료가 필요 없다. 그러나 반복적인 폐렴, 기관지확장증 등이 동반된 경우에는 수술적 치료가 필요하다.

As a core component of a hydropower station, hydro turbines play a vital role in the integration of a power station. Research on the technology of hydro turbine is continuously increasing with the development of water electricity. On the basis of one-dimensional loss analysis, for three-dimension design, there are a lot of dimension of the internal flow passage shapes that are determined by experience. Therefore, the effect of the internal flow passage shapes on the performance and internal flow characteristics of a Francis hydro turbine model is investigated in this study. In this study, the small curvature of runner blade trailing edge shape is good for improving the efficiency of Francis turbine. The straight stay vane leading edge is good for suppressing the secondary flow. Moreover, suitable tongue passage shape and stay vane number improve the performance of the turbine considerably.

Raw ginseng root of Panax ginseng is graded according to its shape and the quality of its internal tissue. A variety of grades are sold with prices according to grade. If an inferior raw ginseng is purchased, the consumer experience an economic loss. This research was conducted in order to explore the possibility of developing a noninvasive method for investigating raw ginseng's internal tissue. It has been determined that computed tomography (CT) scanner images agreed with actual cross-sections of raw ginseng. CT images were obtained to assess the internal portions of raw ginseng, and CT scans of raw ginseng were thoroughly measured using the Hounsfield unit (HU) system, since it allows for a more detailed analysis compared to nuclear magnetic resonance imaging. HU is a measure of attenuation used for CT images, with each pixel being assigned a value using a scale on which air is defined as -1000, water as 0 and compact bone as +1000. It takes about one second to process are slice and produce an image of the raw ginseng by a one channel CT scanner. An image good enough to discriminate the internal tissues can be obtained in 1/24 seconds with a one-channel CT scanner. Using this method, images of raw ginseng can be obtained and the characteristics of the internal tissues can be observed in a short time.

Idiopathic non-cirrhotic portal hypertension (INCPH) is a disease with an uncertain etiology consisting of non-cirrhotic portal hypertension and portal pressure increase in the absence of liver cirrhosis. In INCPH, patients exhibit normal liver functions and structures. The factors associated with INCPH include the following: Umbilical/portal pyremia, bacterial diseases, prothrombic states, chronic exposure to arsenic, vinyl chloride monomers, genetic disorders, and autoimmune diseases. Approximately 70% of patients present a history of major variceal bleeding, and treatment relies on the prevention of complications related to portal hypertension. Autoimmune disorders associated with INCPH are mainly systemic sclerosis, systemic lupus erythematosus and rheumatoid arthritis. To the best of our knowledge, a case of ankylosing spondylitis (AS) associated with INCPH has not been reported thus far. Therfore, we report our experience of a patient with AS accompanied by INCPH, who showed perisplenic varices with patent spleno-portal axis and hepatic veins along with no evidence of cirrhosis on liver biopsy, and provide a brief literature review.

The Purpose of this study was to compare the school life of Korean high school students between Public and proprietary schools, especially focused on their internal experiences and flow. Internal experiences were composed of three dimensions: emotion, cognitive efficiency, and satisfaction. How was classified into four conditions: apathy, boredom, anxiety, and flow. The study results are: 1. Korean high school students felt more flow when they were in public school than in proprietary school,. In public school, they felt relatively more bored, and on the other hand, they were relatively more anxious in proprietary school. 2. Korean high school students felt more positive emotions when they were in public school than in proprietary school. 3. Korean high school students were more involved into study when they were in public school than in proprietary school. 4. Korean high school students were more satisfied when they were in public school than in proprietary school.
