Vertebral deformity in hatchery-reared black sea bream (Acanthoparus schlegelii) fingerlings occurred. Deformed fish had a good appetite but no clinical signs were found except the vertebral abnormality and darkness around the dorsal skin of the deformed vertebra. As more than 90% of the hatchery-reared fish exhibited vertebral abnormality, the fingerlings could not be used for commercial seeds any more. No morphological change in the swim bladder was observed. Histopathological changes on the deformed vertebra, gill, liver, and spleen were observed to clarify the cause of the deformity. The vertebra were irregularly deformed upward with the shape of "V" in an alphabetic character causing the spinal cord and dorsal aorta suppressed. The diameters of the muscle fibers around the deformed vertebra, especially, in the dorsal part, were much smaller and more irregular than those in normal fish, and the gabs between the fiber bundles were enlarged. No evidence of inflammatory responses in the lateral musculature were found. On the basis of normal inflation of the swim bladder, cultural environments for growth of the fingerlings, and histopathological alterations in the muscle, vertebra and gills, it is suggested that high speed of water current in the culturing aquaria between 23 to 30 days after hatching was responsible for the development of vertebral abnormality.

The purpose of this study is to develop an warning system to detect real-time water quality abnormality using a multivariate statistical approach. In this study, we applied principal component analysis among multivariate data analyses which was used for the correlation between water quality parameters considering the real-time algorithm to determine abnormality in water quality. We applied our approach to real field data and showed the utilization of algorithm for the real-time monitoring to find water quality abnormality. In addition, our approach with Korea Meterological Adminstration database identified heavy rain data due to climate change is one of the most important factors to explain water quality abnormality.

Objectives : The purpose of this study is to report one case of Korean medical treatment of patient with developmental abnormality by cerebral palsy whose main symptoms are difference in left and right leg length, foot size and construction of right ankle. Methods : We did retrospective study for one developmental abnormality patient who had been treated by herbal medicine(Samul-tang, Yookmijihwang-tang hap Yijin-tang + Sungjang-hwan), acupuncture, and moxibustion for more than one year. The effects of treatment were evaluated by measurement of leg length, foot size and dorsiflexion ROM. Results : After treatment, length and foot size difference between both leg, ROM difference between both ankle were almost reduced. According to the ratio of the right to the left, leg length was improved from 0.91 to 0.98 and foot size was improved from 0.93 to 0.98. The difference in left and right ankle dorsiflexion ROM was improved from 55° to 27.5°. Conclusions : This clinical case study has demonstrated that Korean medicine may be an safe and effective option for treating developmental abnormality.

The diagnosis of abnormalities in a nuclear power plant is essential to maintain power plant safety. When an abnormal event occurs, the operator diagnoses the event and selects the appropriate abnormal operating procedures and sub-procedures to implement the necessary measures. To support this, abnormality diagnosis systems using data-driven methods such as artificial neural networks and convolutional neural networks have been developed. However, data-driven models cannot always guarantee an accurate diagnosis because they cannot simulate all possible abnormal events. Therefore, abnormality diagnosis systems should be able to detect their own potential misdiagnosis. This paper proposes a rulebased diagnostic validation algorithm using a previously developed two-stage diagnosis model in abnormal situations. We analyzed the diagnostic results of the sub-procedure stage when the first diagnostic results were inaccurate and derived a rule to filter the inconsistent sub-procedure diagnostic results, which may be inaccurate diagnoses. In a case study, two abnormality diagnosis models were built using gated recurrent units and long short-term memory cells, and consistency checks on the diagnostic results from both models were performed to detect any inconsistencies. Based on this, a re-diagnosis was performed to select the label of the second-best value in the first diagnosis, after which the diagnosis accuracy increased. That is, the model proposed in this study made it possible to detect diagnostic failures by the developed consistency check of the sub-procedure diagnostic results. The consistency check process has the advantage that the operator can review the results and increase the diagnosis success rate by performing additional re-diagnoses. The developed model is expected to have increased applicability as an operator support system in terms of selecting the appropriate AOPs and sub-procedures with re-diagnosis, thereby further increasing abnormal event diagnostic accuracy.

Semen was collected from Taiwan commercial local chickens, the diluted sperm suspension were placed in the Gene Pulser cuvette for electroporation. The motility, mortality and abnormality of spermatozoa were evaluated. The fertility and hatchability were also investigated. The results showed that smaller motility and greater mortality or abnormality than the control were found when the capacitances were increased either for spermatozoa treated with small capacitances(0.25, 1, 3 and $25{\mu}$ FD) or treated with high capacitances (125, 250, 500 and $960{\mu}$ FD). In general, greater field strengths also resulted in smaller motility and greater mortality or abnormality of spermatozoa. Although the electroporation decrease the fertility there were no effect on the hatchability.

For the 2 years of farming, at the indoor circulating aquaculture system, four kinds of skeletal deformities were found among 60 Far Eastern catfish, Silurus asotus. Deformities saw jawbone's luxation, abnormality of upper lip and malocclusion. Spinal deformity was most fatal deformities with low weight and small length. Jawbone's luxation had 1 maxilla and 2 mandibles. Abnormality of upper lip had just lip was back over. Malocclusion's left maxilla and right maxilla were not balanced. This experiment was any deformities in this species through the deformity can grasp how it affects.

Many solar, interplanetary and geomagnetic activity parameters have 11-year cycle on the average in sync with solar sunspot number. The galactic cosmic ray (GCR) intensity measured by ground Neutron Monitor (NM) is one of those parameters showing the unprecedented activity levels in the current solar minimum (2008-2009) of solar cycles 23/24. We defined abnormality as the ratio of deviation from long term mean over mean amplitude of solar cycle change. The abnormality distribution map was drawn using all the data of NM stations available online. The implications of those unprecedented levels of GCR intensities of different cutoff rigidities will be discussed.

In a broad sense, the healthcare system refers to the conventional medical service for the field of treatment. From head to toe, our whole body corresponds to the subject of the medical service. In this paper, we discuss the abnormality of flexion and extension in general elbow disease. Flexion and extension refer to flexing and extending of the arm while it is set to be at 90 degrees. In this case, if the angle of the arm is remarkably small or is accompanied with pain, there is an abnormality that occurs in the elbow. We tested the flexion and extension of the elbow for 100 people in their 50s and calculated the number of people for each case. Afterwards, we classified people with abnormalities in flexion and extension and presented the respective treatment methods. In this paper, a system was constructed for the treatment of musculoskeletal disorders.
