Three isolates of Cucumber mosaic virus (CMV) from lily plants showing mosaic and distortion symptoms were detected by reverse-transcriptase polymerase chain reaction (RT-PCR) using primers specific to Cucumovirus genus namely, LK-CMV, LK4-CMV, and LKS-CMV. Restriction enzymes patterns of the RT-PCR products revealed that the lily isolates belonged to subgroup IA of CMV. In terms of biological properties, the lily isolates have highly similar but distinct pathogenicity as reported in other lily strains and ordinary strains of CMV. To characterize the molecular properties, cDNAs containing coat protein (CP) gene and 3' non-coding region (NCR) of RNA3 for the isolates were cloned and their nucleotide sequences were determined. The CP similarity (218 amino acids) was highly homologous (>97％) with that of subgroup I CMV strains. However, an additional 20-nulcleotide long segment was only present in 3' NCR of lily isolates, which form an additional stem-loop RNA structure. By using chimeric construct exchange cDNA containing 3'NCR of LK-CMV into the full-length cDNA clone of RNA3 of Fny-CMV, this additional segment may prove to be significant in the identification and fitness of the virus in lily plants. The pathology of zucchini squash infected by F1F2L3-CMV, a pseudorecombinant virus was showed to change drastically the severe mosaic and stunting symptom into a mild chlorotic spot on systemic leave, compared with Fny-CMV. To delimit the sequence of RNA3 affected the pathology, various RNA3 chimeras were constructed between two strains of CMV. The symptom determinants of F1F2L3-CMV were mapped to the positions amino acid 234, 239, and 250 in 3a movement protein (MP). RNA3 chimeras changed the sequences encoding three amino acids were resulted in alteration of systemic symptom.

Purpose: We intended to observe relation between general symptom and the number of uterine myoma. Methods: We surveyed 948 women from 35 to 45 years old who had received Korean oriental medical questionnaires about general symptom pattern and pelvic ultrasonography at Kyung-Hee university medical center from May, 2007 to October, 2008. After we divided women into three groups (Mono-uterine myoma, Bi-uterine myoma & uterine myoma above 3) by ultrasonography result, we compared general symptom pattern according to the number of uterine myoma. For statistics, we used Kruskal-Wallis Test, SPSS 13.0 for windows. Results: In relation to sleep pattern, severity of dreaming & awaking showed statistical significance according to the number of uterine myoma. In relation to digestion pattern, appetite & heartburn showed statistical significance according to the number of uterine myoma. In relation to evacuation pattern, hardening of stool showed statistical significance according to the number of uterine myoma. In relation to sweating pattern, severity of refreshing after sweating showed statistical significance according to the number of uterine myoma. In relation to the other patterns, hypertonicity of nape neck showed statistical significance according to the number of uterine myoma(p<0.05). Conclusion: The result showed that prevalence of uterine myoma had to be considered in respect of sleep, digestion, evacuation and sweating pattern. we need further study based on this preliminary result.

Objectives Eyes, one of visual inspection regions, present important clues to pathological patterns including deficiency and excess patterns to the clinicians. The purpose of this study was to develop Eyes Inspection Questionnaire (EIQ) and to examine which items among the EIQ were more predictive of clinicians' determination for the deficiency and excess patterns. Methods Nine questionnaire items for Visual Inspection of Eyes were extracted through the literature review. These items were presented to the 4 Korean medical doctors who are specialized in visual inspection to conduct the Delphi method. The Korean medical doctors were asked to rate the importance of each items for the corresponding Visual Inspection of Eyes, using a Likert 5-point scale(the 3 points of importance as a cut-off point). Then, out of 75 photographs submitted to the Society of HyungSang Medicine in 2009, 30 portrait pictures were selected as samples. The samples were copied to make 60 sample pictures, and then randomly assigned to 4 clinicians. The 4 clinicians evaluated the 60 samples for excess and deficiency of the eyes and were asked to check the 6 questionnaire items. The results were recorded as 5-points-scale, and their average and standard deviations were calculated. Intra- class reliability test and multi regression test were performed using SPSS 13. Results Intra-class correlation coefficient (ICC) was between 0.750 to 0.841 (P<0.05). Indices for visual inspection of the eyes were: endowment of the bone structure around the eyes; brightness of the eyes; upward deviation of the eyes; eye shapes; and definition of iris. 76.92% of deficiency symptom patterns and 86.42% of the excess symptom patterns matched the patterns predicted by the visual inspection of the eyes, according to the frequency analysis. According to the multiple regression analysis, were significantly related to the excessive symptoms, and to the deficiency symptoms. Conclusion This study is the first attempt of development for checklist of excess and deficiency of Visual Inspection of Eyes and quantitative measurement of excess and deficiency using the Visual Inspection of Eyes by the visual inspection experts. Still, additional studies are needed regarding the relationship visual inspection methods have with existing standards of diagnosis.

Mutants of the monopartite geminivirus beet curly top virus (BCTV) have been screened for infectivity, systemic movement, replication and symptom development in Arabidopsis thaliana. As known by coding for coat protein, R1 mutant was not infectious and did not move systemically. R2, R3 and L2/L3 mutants produced milder symptoms compared to wild type BCTV but the infectivity was reduced by 40% to 60%. R2 ORF is thought to be involved in the regulation of ssDNA and dsDNA accumulation because only dsDNA was accumulated on R2-infected organs. Disruption of ORF L4 resulted in reduced infections, but the viral DNA was accumulated in infected organs from roots to shoot tips as much as wild type BCTV on Sei-O. In addition, 4 mutants did not produce callus-like tissues on infected organs, suggesting that L4 ORF may play a role in the induction of host cell divisions by virus infection. This result was supported by the patterns of mRNA expression and promoter analysis of the cell cycle marker gene, cycl, on Arabidopsis. cycl mRNA was accumulated on symptomatic organs by wild type BCTV infections but not by L4 mutant. We conclude that the BCTV L4 ORF is essential for symptom developments, specially callus-like formation on infected organs.

Objective : Describe the phenomenon of "clear qi below, turbid qi above" as found in the Somun Eumyangeungsangdaelon (Major Essay on Yinyang Resonances and Appearances 素問 陰陽應象大論) and compare this pattern with water-grain dysentery and flatulence symptom patterns in the Sanghallon (Treatise on Cold Damage). Method : Study the annotation of the Hwangjenaegyeong (Yellow Emperor's Internal Classic 黃帝內經) and compare the results with the Sanghallon's water-grain dysentery and flatulence. Conclusions and Results : The causes of water-grain dysentery and flatulence are associated with the ascending and descending properties of Yin and Yang. Additionally, these symptoms can also be caused by pathogenic heat, turbid pathogenic factors, and interruption of the movement of clear and turbid qi. Aspects of water-grain dysentery resemble several patterns found in the Sanghallon. If caused by a weakness of yang qi, it resembles Sayeoktang (四逆湯) syndrome. Weakness of spleen qi resembles Ijungtang (理中湯) syndrome. Flatulence is similar to fullness in the chest syndrome, which in the Sanghallon is caused by an obstruction of cold qi. If there is excessive cold, water-grain dysentery is similar to the syndrome of Gyeolhyung (結胸). If the qi is not scattered, deficiency syndrome is similar to Gyejigejagyaktang (桂枝去芍藥湯) syndrome and excess syndrome is similar to Mahwangtang (麻黃湯) syndrome. When flatulence is caused by fever in chest, it is similar to Chijasitang (梔子?湯) syndrome. When caused by heat and phlegm build up in chest, it is similar to Sipjotang (十棗湯) syndrome.

An efficient diagnostic approach for real-time operation aiding expert system in chemical process plants is discussed. The approach is based on the hybrid of the simplified symptom tree(SST) and the fault consequence digraph(FCD), representation of propagation patterns of fault states. The SST generates fault hypothesis efficiently and the FCD resolve the real fault accurately. Frame based knowledge representation and object-oriented programming make diagnostic system general and efficient. Truth maintenance system enables robust pattern matching and provides enhanced explain facilities. A prototype expert system for supports operation of naphtha furnaces process, called OASYS, has been built and tested to demonstrate this methodology. Utilization of diversified process symbolic data, produced using dynamic normal standards, overcomes the problem of qualitative Boolean reasoning and enhance the applicability.

Objectives : Hemifacial spasm is painless uncommon disorder characterized by involuntary paroxysmal movement on one side of face. It is known that hemifacial spasm is mainly due to pulsatile compression by vessels at the root exit zone(REZ) of the facial nerve. Microvascular decompression at REZ of the facial nerve has become the standard treatment modality for hemifacial spasm. The authors have analized patients with hemifacial spasm treated with microvascular decompression to evaluate operation result and clinical course after operation. Patients and Methods : From 1992 to 1999, 41 patients with hemifacial spasm underwent this operation. Retrospective analysis of operation results and clinical recovery patterns was done. The length of observation had been more than 6 months in all cases. Results : The ratio of male to female was 1:1.4, and age at operation ranged from 24 to 66 years. Their mean age was 47.6 years and the mean preoperative duration of symptoms was 7.2 years. Most common offending vessels were AICA in 18 cases(48%) and second most common were PICA in 13 cases(31.7%). The rest of them were 3 case in vertebral artery, and 7 cases(13%) in multiple offending vessels. Patterns of improvement after surgery could be divided into 4 clinical types. There was complete recovery in 3 days after operation in 24 cases(58.6%, Immediate complete recovery). There was complete recovery in 3 days after operation, and symptom was recurred partially, which was gradually subsided in 2 weeks after operation in 4 cases(9.8%, Delayed complete recovery type I). There was partial recovery after operation and symptom was compretely disappeared gradually in 6 months after operation in 7 cases(17.1%, Delayed complete recovery type II). Finally, there was partial recovery after operation, and symptom was somewhat remained after 6 months later(14.5%, Delayed partial recovery). Conclusion : In conclusion, microvascular decompression for hemifacial spasm is a safe and reliable treatment modality with good results of improvement and there are 4 recovery patterns in clinical course after operation in our series. Therefore, follow-up observation after microvascular decompression is necessary to evaluate the operative results and complication, especially in the delayed resolved cases.

In Traditional Korean Medicine it is one of basic principle that personality reflects physical conditions. In both of personality and ordinary symptoms, there are some criteria used for diagnosis whether the patient is in cold or hot condition. We studied the relationship between the criteria of cold-hot shown in personality pattern and ordinary symptom pattern. And also analyzed the relativeness in four constitution type. 877 patients who had visited oriental medical hospital and had been confirmed their constitution by drug response were included in this study. Patients filled out the questionnaire composed of personality and ordinary symptom questions. We selected questions related to cold-hot patterns. Next we made personality cold-hot index(PCHI) and ordinary symptom cold-hot index(OSCHI). The two indices were compared and analyzed totally and from the viewpoint of 4 constitution types. The coefficient of correlation between two indices was not high. In Soemin the coefficient was 0.257, in three other constitution it was lower than 0.200 or negative. In Soemin both indices were lower (cold-biased), but in three other constitution no significant results were found. In Tae-emin OSCHI was higher (hot-biased) than PCHI, in Tae-yangin PCHI was higher than OSCHI significantly. Personality is not affected by cold-hot less than expected. The criteria used for diagnosis of cold-hot seems to be biased on Soemin's.

Objectives: We intended to identify factors related to the severity of hot flush of climacteric women from an East-West medical point of view. Methods: We surveyed 446 climacteric women who had received Korean oriental medical questionnaires about clinical symptom patterns and health medical examinations at Kyung-Hee University Medical Center over 1 year, from June 2007 to May 2008. Then, we compared hot flush with clinical symptom pattern and health medical examination result. Results: As the severity of hot flush increased, hypnagogic disorder in sleep pattern, abdominal gaseous distention in digestion pattern, tenesmus in evacuation pattern, yellow or reddish urine in voiding pattern, spontaneous sweating in sweating pattern, chest oppression in psychologic pattern, not-pulling-bedclothes in cold-heat pattern and mouth dryness in craniocervical symptom increased (p<0.05). In relation to digestion pattern, the severity of hot flush showed statistical significance according to prevalence of gastritis diagnosed by gastroscopy and upper GI series(p<0.01). In relation to voiding pattern, the severity of hot flush showed statistical significance according to prevalence of urine protein diagnosed by urinalysis (p<0.05). In relation to sweating, psychologic & cold-heat pattern, triiodothyronine (T3) increase and thyroid stimulating hormone (TSH) decrease were significantly correlated as the severity of hot flush increased (p<0.01). Conclusions: The result showed that hot flush of climacteric women had to be considered in respect of digestion disorder related to gastritis and sweating psychologic cold-heat disorder related to thyroid hormone.

A new methodology is presented to diagnose faults in equipment plasma. This is accomplished by using neural networks as a pattern recognizer of radio frequency(rf) impedance match data. Using a realtime match monitor system, the match data were collected. The monitor system consisted mainly of a multifunction board and a signal flow diagram coded by Visual Designer. Plasma anomaly was effectively represented by electrical match positions. Twenty sets of fault-symptom patterns were experimentally simulated with experimental variations in process factors, which include rf source power, pressure, Ar and O$_2$ flow rates. As the inputs to neural networks, two means and standard deviations of positions were used ...
