A number of essential oils from Mongolian aromatic plants are claimed to have antimicrobial activities. The essential oil of Dracocephalum foetidum, a popular essential oil used in Mongolian traditional medicine, was examined for its antimicrobial activity. Eight human pathogenic microorganisms including B. subtilis, S. aureus, M. lutens, E. hirae, S. mutans, E. coli, C. albicans, and S. cerevisiae were examined. The essential oil of Dracocephalum foetidum exhibited strong antimicrobial activity against most of the pathogenic bacteria and yeast strains that were tested; by both the agar diffusion method and the minimum inhibitory concentration (MIC) assay ($MIC\;range\;was\;26-2592{\mu}g/ml$). Interestingly, Dracocephalum foetidum even showed antimicrobial activity against methicilin-resistant Staphylococcus aureus (MRSA) strains. We also analyzed the chemical composition of the oil by GC-MS and identified several major components, including n-Mentha-1,8-dien-10-al, limonene, geranial, and neral.

On 6 August 2018, heavy rainfall of daily precipitation of more than 200 mm occurred in the Yeong-dong coastal area, and especially, 1-hour precipitation of 93 mm (0251~0351 LST (local standard time) 6 August) at Gangneung station, ranked second in the history of meteorological survey of the station. In this study, this heavy rainfall case over the Gangneung area would be studied to investigate the process in which the heavy rainfall occurred. A developed ridge moved toward the Yeong-dong coastal area from the Maritime Province in Russia. The approaching of the ridge led to the northeasterly cold wind over the coastal region, causing the collision between the incoming northeasterly cold wind, and the humid and warm (convectively unstable) air located over the Yeong-dong area. This collision led to a strong convergence (maximum -206 × 10^-5 s^-1) at 925 hPa level over the vicinity of Gangneung at 0300 LST 6 August, resulting updraft of up to about 4.4 m s^-1 at 700 hPa level over the area. This strong updraft forced to lift rapidly the convectively unstable, warm and humid air layer, located over the vicinity of Gangneung, leading to the heavy rainfall (1-hour precipitation of 93 mm) over the area.

Urban Air Mobility is gaining attention as a solution to traffic congestion and air pollution in large cities, but Gangneung, the case area of this study, is a medium-sized city focusing on tourism and connectivity with other public transport rather than congested traffic. Introducing UAM here focuses on integrating aircraft that carry people, vertiports for vertical take-off and landing, and corridors through which UAM can fly. While research on aircraft and vertiports is actively conducted, studies on corridors are still lacking. Thus, this study selected a route in Gangneung, a medium-sized city in Gangwon Special Self-Governing Province, that allows UAM flights with minimal risk. For this, a safety distance specific to building heights was determined, and the damage radius in case of aircraft crashes was calculated to select the route with the least possible damage during crash or collision incidents. For analysis, aerial photos and digital maps of Gangneung City, along with building information data, were used to create high-resolution orthophotos and digital elevation models. Based on the created data, GIS-based spatial analysis and three-dimensional visualization were conducted, and a suitable UAM route for Gangneung City was determined.

Amiodarone is widely used to control fatal arrhythmia. However, amiodarone therapy is associated with a relatively high incidence of pulmonary toxicity, up to 5 to 10%. Typical symptoms are nonspecific and often manifest as nonproductive cough, dyspnea and interstitial infiltrates in patients with acute pneumonitis or chronic fibrosis. However, hemoptysis is a very rare symptom of amiodarone pulmonary toxicity. We report a case of amiodarone pulmonary toxicity, who presented with hemoptysis and was successfully treated with the cessation of amiodarone, with review of the relevant literature.

Cancer chemopreventive effects can be exerted through the induction of phase II detoxification enzymes and the inhibition of inflammatory responses. In this study, the cancer chemopreventive effects and anti-inflammatory responses of 30 seaweed extracts were examined. The extracts of Dictyota coriacea and Cutleria cylindrica exhibited the high chemoprevention index, having 4.36 and 4.66, respectively. They also activated antioxidant response element at $100\;{\mu}g/mL$ by about 3-fold while did not activate xenobiotic response element. Seven seaweed extracts, Ishige okamurae, Desmarestia ligulata, Desmarestia viridis, Dictyopteris divaricata, D. coriacea, Sargassum horneri, and Sargassum yezoense, showed significant inhibition on nitric oxide (NO) and prostaglandin $E_2$ ($PGE_2$) production in a dose-dependant manner in $5-20\;{\mu}g/mL$. These seaweed extracts could be used as food materials for cancer chemoprevention. D. coriacea could contain potential chemopreventive agents not only that regulate genes via an ARE-dependent mechanism but also prevent the inflammation through inhibition of NO and $PGE_2$ production.

This research aimed to grasp the recognition of the amenity of the university students residing in Gyo-dong residential area in Gangneung city, the local residents residing in Daehag-ro which is near Jungang-ro in downtown and the public servants related to city development in Gangneung city office and thereby propose a plan to improve the amenity of Gangneung city. Based on the result of the research, the university student group around Gyo-dong residential area mostly recognized the amenity and the local residents around Daehag-ro showed insufficient recognition of the amenity and some of related public servants were found to be ignorant of the term amenity. Also, the priorities of amenity indexes identified from these 3 groups commonly showed aliveness requiring green lands and watercourses on top but 2nd priority of each group tended to be different from each other. Through the research result as above, we would like to propose the plan to improve as follows. First, the recognition of the concept of amenity is necessary. Second, green lands and watercourses that were selected by all of the 3 groups as ranking no. 1 should be secured. Third, the value of amenity resources should be evaluated. Gangneung city is a city where mountains and the sea are harmonized together granting abundant god blessed natural resources. But if Gangneung city would imprudently reclaims the excellent god blessed natural environment under the good title of city and housing lands development, its ranking in city competitiveness evaluations will be expected to continue descending. Therefore, as proposed in this research, the thing that has to be implemented with first priority for amenity Gangneung city is the execution of amenity policy to secure the identity of Gangneung city and the aspect of regulations or systems should also be pursued together with the policy.

We report a unique case of synchronous double primary gastric cancer consisting of adenocarcinoma components with micropapillary features and composite glandular-endocrine cell carcinoma components. The patient was a 53-year-old man presenting with a 6-month history of epigastric pain and diarrhea. A subtotal gastrectomy was performed. Histologically, one tumor was composed of micropapillary carcinoma components (50%) with tight clusters of micropapillary aggregates lying in the empty spaces, admixed with moderately differentiated adenocarcinoma components. MUC-1 was expressed at the stromal edge of the micropapillary component. The other tumor was composed of atypical carcinoid-like neuroendocrine carcinoma (50%), adenocarcinoid (30%), and adenocarcinoma components (20%). The neuroendocrine components were positive for CD56, synaptophysin, chromogranin, and creatine kinase. The adenocarcinoid components were positive for both carcinoembryonic antigen and neuroendocrine markers (amphicrine differentiation). This case is unique, due to the peculiar histologic micropapillary pattern and the histologic spectrum of adenocarcinoma adenocarcinoid-neuroendocrine carcinoma of the synchronous composite tumor.
