An 11-year-old neutered male domestic short-haired cat presented with neurological symptoms that developed over a three-month period. These included mental dullness, vocalization, ataxia, and visual impairment. The patient was diagnosed with a primary intracranial tumor at a local animal hospital. After the first diagnosis, the cat was administered hydroxyurea, prednisolone, omeprazole, and gabapentin for 3 months. After the initiation of medical treatment, the patient's clinical symptoms did not improve and the size of the tumor was static on the second magnetic resonance imaging (MRI). The dosage of hydroxyurea and prednisolone was increased for two weeks. The patient's clinical signs improved, and subsequently, a craniotomy was performed. The clinical signs completely resolved six days after surgery. Adjuvant chemotherapy with hydroxyurea was continuously administered after the craniotomy. The patient demonstrated a good clinical status during the nine-month follow-up period. Neoadjuvant chemotherapy has not yet been reported for meningiomas in cats. Further clinical trials with longer follow-up periods and larger patient cohorts will be required to confirm the effectiveness of neoadjuvant chemotherapy with hydroxyurea in feline meningioma.

In spite of abundant clinical resources of stroke patients, the objective and logical data analyses or diagnostic systems were not established in oriental medicine. In the present study we tried to develop the statistical diagnostic tool discriminating the subtypes of oriental medicine diagnostic system, syndrome differentiation (SD). Discriminant analysis was carried out using clinical data collected from 1,478 stroke patients with the same subtypes diagnosed identically by two clinical experts with more than 3 year experiences. Numerical discriminant models were constructed using important 61 symptom and syndrome indices. Diagnostic accuracy and prediction rate of 5 SD subtypes: The overall diagnostic accuracy of 5 SD subtypes using 61 indices was 74.22%. According to subtypes, the diagnostic accuracy of "phlegm-dampness" was highest (82.84%), and followed by "qi-deficiency", "fire/heat", "static blood", and "yin-deficiency". On the other hand, the overall prediction rate was 67.12% and that of qi-deficiency was highest (73.75%). Diagnostic accuracy and prediction rate of 4 SD subtypes: The overall diagnostic accuracy and prediction rate of 4 SD subtypes except "static blood" were 75.06% and 71.63%, respectively. According to subtypes, the diagnostic accuracy and prediction rate was highest in the "phlegm-dampness" (82.84%) and qi-deficiency (81.69%), respectively. The statistical discriminant model of constructed using 4 SD subtypes, and 61 indices can be used in the field of oriental medicine contributing to the objectification of SD.

비점오염원은 세정에 의해 하수관 내로 유입되어 수계까지 흘러 수계의 오염부하를 가중시킬 뿐만 아니라, 관의 상태에 따라 누수 및 월류를 야기하여 오염을 일으킨다. 이에 따라 하수관거의 유지관리 및 환경오염 방지를 위한 관거내 하수의 유량, 수질, 불명수 및 월류 등을 효율적으로 관리하기 위한 모니터링의 필요성이 증가하고 있다. 그러나 하수관거의 경우, 지하에 설계되며 그 구조 및 연결이 복잡한 특성으로 인해 실제 하수관거에 대한 모니터링은 쉽지 않다. 본 연구에서는 시스템해석이론에 기초한 하수관망 오염제거 해석과 관망 모니터링 및 이상진단방법을 제시하였다. 먼저 하수관망 공정모사 프로그램인 Stormwater & Wastewater Management Model for expert (XP-SWMM)을 이용하여 관망 내의 오염물질의 거동패턴을 해석하였다. 둘째, 다변량 통계 모니터링을 이용하여 하수관망 내의 수질 모니터링 및 하수관망 유출을 탐지하는 관망 이상 진단을 수행하였다. 정적/동적 상태 시스템에 기초한 하수관망 오염 매카니즘 해석결과, 강우시 총질소와 총인 부하량이 비강우시보다 급격하게 증가함을 확인하였으며, 이는 수계의 오염부하를 가중시킬 것으로 판단되다. 이에 따라 하수관망 내 유출은 강우로 생긴 유량 및 유입오염물질의 농도 증가로 인한 관망이상으로 사료된다. 제안된 하수관망 모니터링 및 이상진단 기법은 도시 유역에서의 비점오염원 관리와 지속적인 모니터링에 있어 효과적으로 사용될 수 있을 것으로 예상된다.

The objective of this study was to investigate the diagnosis and treatment of Sjogren's syndrome(SS) such as syndrome differentiation and herbal medicine by reviewing Chinese traditional medicine's journals. The journal search was carried out using China National Knowledge Infrastructure(CNKI) and PubMed from January 2007 to July 2012. Searching key words were the various combination of "Sjogren's syndrome", "Traditional Chinese Medicine", "herbal medicine", and "syndrome differentiation". The final selection of 57 studies were extracted and summarized by two researchers independently. The syndrome differentiation was classified as yin deficiency with fluid depletion, yin deficiency with dryness heat, dryness toxin with yin damage, internal obstruction of static blood, dual deficiency of qi and yang, dampness-heat obstructing, wind with external contraction, liver qi depression, blood deficiency and wind-dryness, dual deficiency of yin and yang, and internal obstruction of phlegm-blood stasis. Liriope platyphylla(麥門冬), Rehmania glutinosa(生地黃), and Scrophularia buergeriana(玄蔘) were primarily prescribed to tonify yin, engender fluid and moisten dryness.

Background: Hemiplegic patients usually have difficulty maintaining balance. Balance training is a major component of there habilitation program for patients with neurological impairment. The purpose of this study was to investigate the effects of PLS(Posterior Leaf Spring), FES(Functional Electrical stimulation), treadmill training, and neurodevelopmental treatment on the improvement of balance in patients with hemiplegia. Methods: We looked into published studies from Dankook University’s electronic library databases of RISS4U, KMbase, NCBI, and MEDLIS concerning the effectiveness of any form of intervention leading to improvement of balance. All types of studies relevant to the topic that were published in English during the time period of 1986 to 2005 were included. Results: 1. There were significant differences in standing balance, dynamic activity balance, and gait speed between barefoot subjects and subjects who wore SPAFO and HPAFO(p<.05). 2. The changes in ROM and FRT related to sex, age, height, and weight part of the diagnosis, as well as experience relapse, was of meaningless value. Changes in ROM related to the duration of pain and experiences of falling down were also meaningless. However, FRT showed significant static differences(p<.05). 3. The body-weight-support treadmill training scoring of standing balance, step length, and a timed 10m walking test showed definite improvement. 4. The proprioceptive control approach improved dynamic balance in patients with hemiplegia. Conclusion: Consequently, further study is needed to verify methods when physical therapists are researching balance ability in hemiplegic patient.

The fact that the reliability of IGBTs has become a more and more significant aspect of power converters has resulted in an increase in the research on the open circuit (OC) fault location of IGBTs. When an OC fault occurs, a zero-current phenomena exists and frequently appears, which can be found in a lot of the existing literature. In fact, fault variables have a very high correlation with the zero-current interval. In some cases, zero-current interval actually decides the most significant fault feature. However, very few of the previous studies really explain or prove the zero-current phenomena of the fault current. In this paper, the zero-current phenomena is explained and verified through mathematical derivation, based on two-level and three-level NPC static var generators (SVGs). Mathematical models of single OC fault are deduced and it is concluded that a zero-current interval with a certain length follows the OC faults for both two-level and NPC three-level SVGs. Both inductive and capacitive reactive power situations are considered. The unbalanced load situation is discussed. In addition, simulation and experimental results are presented to verify the correctness of the theoretical analysis.

Background: A cancer survivor is defined as anyone who has been diagnosed with cancer, from the time of diagnosis through the rest of their life. The purpose of this study was to examine whether physical functions, health-related outcomes, nutritional status and blood markers in community-dwelling cancer survivors aged 75 years and older are different from those who do not have cancer Materials and Methods: Two hundred seventy-five participants were asked by physicians, nurses, and physical therapists, questions regarding cancer history in a face-to-face interview. Data were collected for demographic information, physical functions, such as handgrip strength, knee extension power, abdominal muscle strength, static standing balance, walking speed and the timed-up-and-go test, health-related outcomes, nutritional status, and blood markers. The measured parameters of survivor diagnosed with cancer were compared with those without a history of cancer. Results: Thirty-seven older adults were previously diagnosed with cancer. Female cancer survivors had lower knee extension power (p<0.05), abdominal muscle strength (p<0.05), walking speed (p<0.05), timed-up-and-go test score (p<0.05), and time to spend on walking per day (p<0.05) than older women without a history of cancer. In men, none of the measured parameters were significantly different between cancer survivors and older men with no history of cancer. Conclusions: The present study shows that partial physical function of women cancer survivors aged 75 years and older differs from that in women with no history of cancer.

Sensory dysfunction following the injury of the inferior alveolar nerve requires objective examination to get a reproducible data and to provide necessary treatment. This study was designed to evaluate if the SEP(somatosensory evoked potentials) of the mental nerve can be used as an objective method for the diagnosis of nerve injury and sensory disturbances. The subjects were nineteen patients ($37.4{\pm}11.3$ years old) who had been suffered from sensory disturbance of the unilateral lower lip and mental region for over 6 months after the inferior alveolar nerve injuries confirmed by the microsurgical explorations. The clinical neurosensory tests as SLTD(static light touch discrimination), MDD(moving direction discrimination), 2PD(two point discrimination), PPN(pin prick nociception) and accompanied pain were preceded to electro-physiologic examinations as SEP. The score of sensory dysfunction (sum score of all sensory tests) ranged from 0 to 8 were compared to the latency differences of the mental nerve SEPs. The correlation between clinical sensory scores and SEPs were tested by Spearman nonparametric rank correlation analysis, the differences in SEP latency by Kruskal-Wallis test and the latency differences according to PPN and accompanied pain by Mann-Whitney U test. This study resulted that the difference of the latencies between normal side and affected side was $2.22{\pm}2.46$ msec and correlated significantly with the neurosensory dysfunction scores (p=0.0001). Conclusively, the somatosensory evoked potentials of the mental nerve can be a useful diagnostic method to evaluate the inferior alveolar nerve injuries and the change of sensory dysfunction to be reproduced as an objective assessment.
