  • Lophatheri Herba is the aerial part of Lophatherum gracile Bronghiart(淡竹葉, Gramineae). 25~75 cm in length. Stem: cylindrical with nodes, empty inside, externally pale yellowish green. Leaf: dehiscent of lanceolate lamina, shrunken and rolled, 5~20 cm long, 10~35 mm wide; surface: pale green ~ yellowish green, parallel-formed with veins of square reticulate, more distinct of appearance on the lower surface. Banbusae Caulis In Taeniam is the stringy strip derived from the stem with the peeled-off epidermis of Phllostachys nigra Munro var. henosis Stapf, and Phllostachys bambusoides Siebold et Zuccarini(竹葉, Gramineae). Irregular in size and shape, thin plane ~ strip-shaped, sometimes powdery, sometimes 1~3 mm thick. Outer surface: pale green ~ yellowish green, sometimes grayish white L. gracile and P. nigra have different origins although they show similar morphologic features. We were able to distinguish between L. gracile and P. nigra which are almost indistinguishable through this study. AFLP(Amplifide Fragment Length Polymorphism) was more suitable for identifying differences between L. gracile and P. nigra in comparison with other genetic analysis using chemical analysis. Therefore. molecular biological methods are believed to be useful for discovering origins of herbal medicines.

  • Purpose: Anaplastic large cell lymphoma, has the following three characteristics of a malignant lymphoma; 1) An irregular large nucleus, called pathologic atypical cells, 2) Eosinophilic cytoplasm, 3) Immunologically positive for Ki-1. Anaplastic large cell lymphoma occurs mostly in the lymph nodes, but about 40% has been observed to occur in other tissues. Skin is the one of the main sources of origin and it is called 'primary cutaneous anaplastic large cell lymphoma'. Methods: A 69-year-old male patient with an erythematous nodule, sized $1.5{\times}1.7cm$ on his right hand dorsum was excised under local anesthesia and on biopsy was diagnosed as 'Dermatofibrosarcoma Protuberans'. Three months after the local excision and biopsy, same natured mass reoccurred in the same region, and then spontaneous regressed after three weeks. However, metastatic large mass of $4.0{\times}5.0cm$, of same nature was observed on the elbow. The large mass was operated with wide excision and biopsy. Results: On final diagnosis, with an immunofluorescent stain with CD30(Ki-1), 'Primary cutaneous large cell lymphoma' was made. After follow up for three years, we did not observed recurrence and metastasis. Conclusion: We have reported that we have diagnosed primary cutaneous large cell lymphoma and treated without recurrence and metastasis.

  • Ki-1 positive anaplastic large cell lymphoma is a newly described high-grade lymphoma and is defined by histopathological and immunologic criteria. We experienced a case of systemically involving Ki-1 positive anaplastic large cell lymphoma in a 44 year-old female which initially manifested as pleural effusion. Abdominopelvic CT scan showed the evidence of marked lymphadenopathy in retroperitoneal and both external and inguinal lymph nodes. On cytologic examination of pleural fluid, tumor cells revealed pleomorphic large isolated cells with prominent nucleoli and abundant cytoplasms. The nuclei were large with irregular profiles including some deep invaginations. Also, occasional multilobed/multinucleated and binucleated nuclei were seen. Immunohistochemical examination was performed to differentiate from the undifferentiated adenocarcinoma, Hodgkin's disease, non-Hodgkin's lymphoma and malignant histiocytosis. The neoplastic cells were positive for leukocyte common antigen, CD3, CD30(Ki-1) but negative for cytokeratin, epithelial membrane antigen, and CD15. A histologic diagnosis of Ki-1 positive anaplastic lymphoma was made by biopsies of the inguinal lymph node, polypoid lesions of the stomach and cecum.

  • In Ad Hoc Networks, a connection breaks due to the irregular movement of mobile nodes and the inherent characteristics of the wireless medium such as the interference and the multi-path fading. AODV, a typical on-demand routing protocol in Ad Hoc networks, uses the local repair mechanism to cope with the connection breaks. This paper proposes an efficient route maintenance scheme for AODV, named as AODV-ERM, by utilizing hello messages. The proposed AODV-ERM scheme can recover some link breaks efficiently without relying on the expensive local repair process, thereby reducing the repair time. To show the effectiveness of the proposed scheme, we performed extensive simulation with NS2. The simulation results show that the proposed scheme can reduce the repair time effectively and thus, increase the overall packet delivery ratio.

  • In the fourth industrial revolution, which has become an issue now, we have been able to receive instant analysis results faster than the existing slow speed through various Big Data technologies, and to conduct real-time monitoring on mobile and web. First, various irregular sensor Data is generated using IoT device, Raspberry Pi. Sensor Data is collected in real time, and the collected data is distributed and stored using several nodes. Then, the stored Sensor Data is processed and refined. Visualize and output the analysis result after analysis. By using these methods, we can train the human resources required for Big Data and mobile related fields using IoT, and process data efficiently and quickly. We also provide information that can confirm the reliability of research results through real time monitoring.

  • To suggest the basic data for exporting enlargement of sweet pepper (Capsicim annuum L.), this study compared plant growth and fruit setting characteristics among 8 cultivars of red line. At 23 weeks after planting, plant height was long in 'Debla', 'Cupra', 'Thialf', 'Viper' and 'Spider', and was shot in 'Scirocco', 'Ferrari', 'Special'. 'Debla' had a few nodes number and long internode length. For 23 weeks after planting, weekly increment of plant hight and number of developed node were many in 'Debla' and 'Cupra', were few in 'Special' and 'Ferrari'. Average fruits of over 200 g was harvested in 'Viper', 'Spider' and 'Debla', average fruits of range of 180~200 g was harvested in 'Special' and 'Thialf', and average fruits of range of 160~180 g was harvested in 'Scirocco' and 'Cupra'. Cultivars harvested heavy fruits except in 'Debla' was high in percentage of irregular fruit size. Number of fruit setting on plant was many in 'Cupra' and 'Ferarri', ripening first was many in 'Ferarri', 'Scirocco' and 'Viper'.

  • This research aims at comparison of climatic conditions of sweet pepper's greenhouse between Korea (KOR) and the Netherlands (NL) to find out the reason of much lower yield in KOR than NL focus-ing on greenhouse climatic conditions. Hence, greenhouse climate data were obtained from each one commercial glasshouse in both countries. The crops (cv. 'Derby') were grown on rockwool slab with two stems per plant with 3.75plants/$m^2$ in KOR and three stems per plant with 2.5plants/$m^2$ or four stems per plant with 1.875plants/$m^2$ in NL. Even though plant density was differed but stem density was on the same to 7.5stems/$m^2$. There was no significantly difference on weekly growth of sweet pepper plant both countries, whereas harvested nodes to whole nodes of NL's plant was more than two times higher compared to KOR. The averaged daily global radiation during the whole growing periods was 14.5MJ/$m^2$/day in KOR and l2.1MJ/$m^2$/day in NL. Averaged 24h temperature was similar to both glasshouse as $21.6^{\circ}C$ in KOR and $21.2^{\circ}C$ in NL during the whole growing periods, however the variance was higher in KOR than NL. Humidity deficit (HD) was observed higher in KOR during the whole growing periods. Averaged day $CO_2$ concentration was measured contrary pattern in both countries because of heating to greenhouse on NL winter season. Averaged 24h temperature and day $CO_2$ concentration to daily global radiation was regular pattern in NL, whereas there are large scatter in KOR. Consequently, more irregular greenhouse climate condition in KOR could be induced irregularly crop growth.
