Renal hemangioma is an uncommon benign tumor which usually causes painless or painful gross hematuria. Its preoperative diagnosis is extremely difficult or even impossible. We experienced three cases of renal hemangioma, located mainly at the pelvocalyceal junction or in the inner medulla. US demonstrated variable echogenecity, and CT revealed a lack of significant enhancement. Where there is gross hematuria in a young adult, especially when the renal mass located in the pelvocalyceal junction or inner medulla shows little enhancement on CT, renal hemangioma should form part of the differential diagnosis.

Device discovery for D2D (device-to-device) communication enables a device to discover other devices in order to initiate communication with them. Devices should perform the discovery phase using a small quantity of radio resource in a short time and be able to reduce the load of the base station. Legacy device discovery schemes have focused on discovering as many target devices as possible. However, it is not appropriate for peer-to-peer D2D communication scenario. Further, synchronization problems are an important issue for discovery signal transmission. This paper proposes a discovery method that one requesting device discovers a specific target for communication. Multiple antenna beamforming is employed for the synchronization between the base station and a target device. The proposal can reduce the load of the base station using the information that it already maintains and improve the reliability of the device discovery because two times of synchronizations using beamforming among the base station and devices can make the exact discovery of a target device with mobility possible.

We are inundated with visual media; countless such media, ranging from Hollywood blockbusters, American drama, Korean films with enormous budgets to independent films, appeal to our sensibility and engage our empathy and insight. The making of mega-hits that attract millions and a drama of viewer ratings of over forty percent lies in how persuasive the sensibility of the narratives are to an audience from a different milieu and personality. It leads to a question: how can empathy of such a varied group of people be won towards the perspective of directors and authors who come from different nationality and ethnicity to themselves? In exploring the issue, I aim to adopt a psychoanalytical view of human psychology, into consciousness and unconsciousness. Freudian psychoanalysis and Jungian analytic psychology in depth psychology underpin my analysis of visual media. It further enables my examination of unconsciousness applied to spatial design, which is elementary in visual media. In sum, this research aims to improve understanding of spatial design in films, a product of creative human consciousness, by interpreting this as an outcome of the unconscious. This is to apply the concept of collective unconscious in Jung's analytical psychology.

A new species belonging to the genus Alternaria was isolated from the necrotic leaf spots of Brassica rapa subsp. pekinensis in Yuseong district, Daejeon, Korea. It is an occasional isolate, not an etiological agent, which is morphologically similar to A. broccoli-italicae, but differs in conidial size and conidiophore shape. Phylogenetic analysis using the sequence datasets of the internal transcribed spacer (ITS) region of the rDNA, glyceraldehyde-3-phosphate dehydrogenase (gpd), and plasma membrane ATPase genes showed that it is distantly related to A. broccoli-italicae and closely related to Alternaria species in the section Pseudoalternaria, which belonged to a clade basal to the section Infectoriae. Morphologically, the species is unique because it produces solitary conidia or conidial chains (two units), unlike the four members in the section Pseudoalternaria that produce conidia as short branched chains. It exhibits weak pathogenicity in the host plant. This report includes the description and illustration of A. brassicifolii as a new species.

Glassy cell carcinoma is an unusual neoplasm of the uterine cervix that accounts for $1{\sim}2%$ of all cervical malignancy. It is a rapidly progressive and biologically aggressive disease with poor response to therapy. This tumor is considered to be a poorly differentiated mixed adenosquamous carcinoma. The cytologic findings are characterized by tumor cells arranged predominantly in syncytial like aggregates and an inflammatory background. The tumor cells have moderate amounts of eosinophilic or amphophilic cytoplasm, which is often finely granular. The nuclei are relatively large and have fine chromatin with prominent eosinophilic nucleoli. Cytologically, glassy cell carcinoma is most likely to be confused with large cell nonkeratinizing squamous cell carcinoma and with atypical reparative cells. Herein, we report three cases of glassy cell carcinoma of the uterine cervix diagnosed by cervicovaginal smear and confirmed by histologic section with review of literatures.

Purpose: This study aims to conduct an integrated literature review of infection control studies conducted by nursing care workers in long-term care facilities in Korea. Methods: Through the domestic search engines RISS and KISS, seven articles were selected by searching for theses and academic journals published in Korea from 2008 to January 2020. Results: In total, six research studies and one intervention study out of seven studies were analyzed. Measurement tools for examining the knowledge and performance of infection-related care workers consisted of skin infection, aspiration pneumonia, urinary tract infection, and hand hygiene. Factors affecting nursing care workers' infection management performance were infection management knowledge, education level, health status, and importance awareness. Conclusion: This study showed it is necessary to develop a tool that can accurately measure nursing care workers' infection management knowledge and performance. In addition, it is necessary to develop an intervention program for nursing care workers' infection control.

Purpose: The purpose of this study was to analyze the effects of a pruritus intervention program on pruritus and sleep satisfaction in patients undergoing hemodialysis. Method: This study was designed for a nonequivalent control group repeated measures quasi-experimental study. Hemodialysis patients were recruited from a kidney center at a university hospital located in G city, Korea. The subjects consisted of 43 patients 21 for the experimental group and 22 for the control group. The 2-week pruritus intervention program was given to the experimental group only. An analytical survey was done before and after the pruritus intervention program. Result: There was a significant decrease in pruritus and increase in sleep satisfaction in the experimental group compared to the control group. There was significant improvement in clinical symptoms and sleep satisfaction after completing the pruritus intervention program in the experimental group. Conclusion: Pruritus intervention program in hemodialysis patients decreased pruritus severity and increased sleep satisfaction, which can be used as an efficient nursing intervention for hemodialysis patients.

Flavonoid are large group of the polyphenolic compounds which are distinguished by an aromatic or phenolic ring structure and the phenolic compounds are induced by microbial infection, ultraviolet radiation, temperature and chemical stress. They are known for their antioxidant activity, anti-allergic, anti-inflammatory, anti-microbial and anti-cancer activities. In this study, changes in flavonoid content were investigated using heterologous chalcone isomerase (CHI) expression system. Also, phenolic compounds level was measured to examine the relation between flavonoids and phenols contents. Explants of lettuce (Lactuca sativa L.) were transformed with Agrobacterium tumefaciens LBA 4404 strain containing pFLH-CHI (derived from pPZP2Ha3) vector constructed with CHI gene from Brassica rapa. The putative transgenic plants were confirmed by genomic DNA PCR analysis. Also the transcription levels of the gene were analyzed by semi-quantitative RT-PCR with gene specific primers. The total flavonoid contents were increased at $T_0$ and $T_1$ generations over 1.4 and 4.0 fold, respectively. Total phenol contents also increased at $T_1$ generation. These results indicate that CHI gene plays an important role to regulate the accumulation of flavonoids and its component changes.

1. "GuGeupGanIBang(救急簡易方)" is a Korean annotation emergency treatment book made by scholars that were learned in medicine such as Naeuiwon(內醫院) head Yoo n Ho(尹壕) Seo Ha gun(西河君) Im Won jun(任元濬) GongJoChamPan(工曹參判) Park An sung(朴安性) Hanseongbu Jwayun(漢城府左尹) Gwon Geon(權健) SungRokDaeBuHaengByeongJoPanSeo(崇祿大夫行兵曹判書) YangCheonGun(陽川君) Heo Jong(許琮) following instructions of King Sungjong. This book was made by supplementing "EiBangRyuChwi(醫方類聚)", "HyangYakJeSengBang(鄕藥濟生方)" and "GuGeupBang(救急方)". When Yoon Ho presented it the king in May 1489(the 20th year of Sungjong), the king made the governors of each province publish it in large numbers, allowing common people to have this book and find the treatment immediately and save lives. 2. "GuGeupGanIBang(救急簡易方)" consists of 8 volumes, 127 chapters. Contents on stroke is the largest section. Separate chapters for gynecology and pediatrics let children that are easily ill and women that cannot get treatment freely be taken care of. It is an first aid medical book covering all ages, fulfilling its original purpose.

Salivary duct carcinoma is an uncommon aggressive malignant epithelial neoplasm with similarity to intraductal carcinoma of the breast. This neoplasm occurs most often in the parotid gland of middle-aged and older males. About 7% of reported tumors occured in the submandibular gland. The report of salivary duct carcinoma with calcification is rare. We report a case of salivary duct carcinoma with calcification in the submandibular gland. The patient was a 73-year-old male with a mass of the right submandibular gland for 1 year. On the fine needle aspiration cytology, the aspirate showed scant cellularity, small clusters of tumor cells, and scattered small calcifications. Nuclei of the tumor cells showed mild pleomorphism and round to oval in shape, and cytoplasm was abundant and finely granular. Nucleoli were indistinct and necrosis was not noted. There were no cribriform or papillary arrangements of tumor cells. Cytologlc findings of salivary duct carcinoma are variable depending on histologic findings, and calcifications could be an additional cytologic findings.
