In this study, a species of Rhabdocoela is reported from Korea for the first time. The kalyptorhynch Alcha sinensis Wang & Hu, 2019, was collected from the intertidal zone of Anmyeon Island. Compared to the original study on A. sinensis and previous studies on A. evelinae, we provide additional detail of these two species through pictures of the stylet and a improved description of the prostate stylet type III, which is composed of a bowtie-shaped base and two pairs of heteromorphic plates with fringed or serrated edges. Two plates are also provided with a rounded "blade". Also, we discuss the importance of the prostate stylet type III as a diagnostic character. After a thorough comparison of the descriptions of A. evelinae Marcus, 1949, and A. sinensis, we conclude that the Korean specimens belong to the latter species. Finally, we discuss the difficulties of interpreting diagnostic characters of the small and complex prostate stylet type III within the genus Alcha.

Objective : This study reports on the case of a patient with irritable bowel syndrome (IBS) diagnosed by the Shanghanlun disease pattern identification diagnostic system (DPIDS). We tried to verify the therapeutic effects of Soseunggi-tang (SSGT) administration and pathological character. Methods : The patient was administered SSGT for 31 days. We observed the progression of symptoms, patient compliance, and the presence of side effects. The progression of IBS was evaluated based the on Gastrointestinal Symptom Rating Scale (GSRS). Abdominal pain, flatus, visual findings, and patient statements were also assessed. Results : According to the DPIDS, the patient was diagnosed with Yangmingbing (陽明病). As a result, his GSRS score dropped from 15 to 5, the visual analog scale (VAS) score for abdominal pain lowered from 9 to 4, and the VAS score for flatus decreased from 8 to 4. The stool type changed from diarrhea to a loose stool form. Conclusions : SSGT showed therapeutic effects on the patient diagnosed with IBS and Yangmingbing.

Phytoliths of leaf blades of Oryza were studied by light and scanning electron microscopy in order to assign the diagnostic character and taxonomic key for the genus. Some phytoliths such as stomatal apparatus, long-cell and short-cell, existing at the same position on the abaxial side of leaf blade, were intensively investigated because of their various forms documented in a previous study. These characters have value either for testing infrageneric classification or for identifying taxa within the genus. Stomatal phytolith is formed by integration of several kinds of sources, such as the guard and subsidiary cell and the papillae. The stomatal phytolith, characterized by not only the absence and presence of phytolith originated by the papillae developed on the guard and subsidiary cell but also their pattern of arrangement, shows various morphologies, and these features have congruent with the infrageneric classification such as section and/or series. Long-cell phytolith is characterized by the absence/presence, arrangement and morphology of phytoliths originated by the papillae on the cell surface. These features may hardly have any systematic relevance within the genus, but contain some informations for identifying of species. All of short-cell phytoliths found are silica body. They form various shapes like cross, bilobate, saddlelike and trilobate, and these features are consistent with infrageneric classification such as section and/or series. Also, some characters, the absence/presence of band of short cell phytolith within costal strip, the absence/presence of saddlelike phytolith within intercostal strip and the number of band of short cell phytolith within costal strip are various according to taxa, but these features do not fall into infrageneric classification. Some taxonomic keys on the phytoliths of stomatal, long-cell and short-cell were developed by their features, and the agreement between these characters and infrageneric classifications was also discussed.

Objective : The aim of this study is to establish the value of hand elevation test as a reproducible provocative test for the diagnosis of carpal tunnel syndrome (CTS). Methods : We had a prospective study of 45 hands of 38 patients diagnosed with CTS between April 2005 and February 2009. The diagnosis of CTS was based on the American Academy of Neurology clinical diagnostic criteria. Experimental and control group patients underwent Tinel's test, Phalen's test, carpal compression test and hand elevation test as provocative tests for CTS. Results : We used chi-square analysis to compare Tinel's test and Phalen's test, carpal compression test with hand elevation test. The sensitivity and specificity of the hand elevation test is 86.7% and 88.9% each. Tinel's test had 82.2% sensitivity and 88.9% specificity. Phalen's test had 84.4% sensitivity and 86.7% specificity. Carpal compression test had 84.4% sensitivity 82.2% specificity. Comparisons of sensitivity and specificity between hand elevation test and Tinel's test, Phalen's test, and carpal compression test had no statistically significant differences. To compare the diagnostic accuracies of four tests, the area under the non-parametric receiver operating character curve was applied. Conclusion : The hand elevation test has higher sensitivity and specificity than Tinel's test, Phalen's test, and carpal compression test. Chi-square statistical analysis confirms the hand elevation test is not ineffective campared with Tinel's test, Phalen's test, and carpal compression test.

Recently, with increasing efficiency of DSC (photo-electrochemical using a nano-particle), The Performance of DSC solar generation system also needs improvement. The approach consists of a Fly-back DC-DC (transfer ratio 1:10) converter to boost the DSC cell voltage to 300VDC. The four switch (MOSFET) inverter is employed to produce 220V, 60Hz AC outputs. High performance, easy manufacturability, lower component count., safety and cost are addressed. Protection and diagnostic features form an important part of the design. Another highlight of the proposed design is the control strategy, which allows the inverter to adapt to the: requirements of the load as well as the power source. A unique aspect of the design is the use of the DSP TMS320LF2406 to control the inverter by current and voltage feed-back. Efficient and smooth control of the: power drawn from the DSC Cell is achieved by controlling the front end DC-DC converter in current mode.

In this paper, we propose a new algorithm emulating the DNA characteristics for noise-tolerant pattern matching problem on digital system. The digital pattern matching becomes core technology in various fields, such as, robot vision, remote sensing, character recognition, and medical diagnosis in particular. As the properties of natural DNA strands allow hybridization with a certain portion of incompatible base pairs, DNA-inspired data structure and computation technique can be adopted to bio-signal pattern classification problems which often contain imprecise data patterns. The key feature of noise-tolerance of DNA computing comes from control of reaction temperature. Our hardware system mimics such property to diagnose cardiovascular disease and results superior classification performance over existing supervised learning pattern matching algorithms. The hardware design employing parallel architecture is also very efficient in time and area.

Objective: This report aimed to study fibromyalgia's diagnostic criteria, differential diagnoses and its pathology from the viewpoint of oriental medicine. Method: We observed and diagnosed a female patient who complained of prolonged whole body pain, even several times hospitalized for treatment. Result: The patient's symptoms correspond with fibromyalgia and we ruled out other suspected diseases. Conclusion: Fibromyalgia is prone to be misdiagnosed because the patient has complicated symptoms such as various pains and chronic fatigue as well as depression unexplained by medical tests. Furthermore, the symptoms often never disappear completely, although it isn't progressive or life-threatening, and can be improved. So accumulation of data and analysis from the viewpoint of oriental medicine is necessary for development of oriental medical standard treatment.

Carotid body tumor is rare tumor in the neck. Among the pathologic conditions affecting paraganglionic tissue. the carotid body is most frequently involved. There are controversies in terms of natural history. biological behaviors, technique of excision, risks of the operation. Carotid angiography is the most valuable diagnostic aid and important for the planning of therapy. Definite treatment of carotid body tumor is surgical excision. Considerable degree of caution and vascular surgical armamentation are required because of its anatomical location and profuse vascularity. Surgical removal of this kind of paraganglioma must be predicated upon several factors such as tumor character. location. symptom, vascularity, and surgeon's ability.

An unrecorded Fissidens species, Fissidens protonemaecola Sakurai (Fissidentaceae, Bryophyta), was newly discovered in Korea during an investigation bryophyte flora. In this study, we examined the morphology of F. protonemaecola in Korea. This species was found in soil along a train through a shaded backslope of Mt. Bukbyeongsan (elev. 80 m) on Geojedo Island and on Mt. Gogeunsan (Oreum; elev. 280 m) on Jejudo Island, Korea. This species has dwarfish bud-like shoots scattered on persistent protonemata. An important feature of the protonemata is a diagnostic character of F. protonemaecola that clearly distinguishes it from other Fissidens species. Its Korean name is given as "Cho-rok-sil-bong-hwang-i-kki," inferred from the characteristic protonemata of the species.

Eleven Gonioctena species have been recorded in the Korean Peninsula. Most species in the genus have very similar coloration and morphology. The male genitalia is generally used as the only reliable diagnostic character differentiating closely related species, but it is still difficult to identify females to species accurately. Here, we determined the COI barcodes of two Gonioctena species described from Korea and give morphological descriptions. The interspecific genetic divergence (Kimura 2-parameter) among the Gonioctena ranged from 0.073 to 0.138 and averaged 0.108. The pairwise genetic distance between the two Korean species(0.102) is similar to the average interspecific divergence. We predict that these analyses will help to resolve taxonomic issues and find cryptic species.
