  • Asian dust(or yellow sand) occurs mainly in spring and occasionally in winter in east Asia, when the weather conditions are under an upper trough/cut-off low and surface high/low pressure system during blocking episode days associated with the stationary patterns of the upper level jet stream. The transport mechanism for Asian dust during the blocking episode days in spring 2001 was analyzed using the TOMS aerosol index and meteorological mesoscale model 5(MM5). Based on the E vector, an extension of an Eliassen-Palm flux, the blocking episode days were found to be associated with the development of an upper cut-off low and surface cyclones. Concurrently, the occurrence of dust storms was also determined by strong cold advection at the rear of a jet streak, which exhibited a maximum wind speed within the upper jet stream. As such, the transport mechanism for Asian dust from China was due to advection of the isentropic potential vorticity(IPV) and isentropic surfaces associated with tropopause folding. The transport heights for Asian dust during the blocking episode days were found to be associated with the distribution of the isentropes below the IPV At the same time, lee waves propagated by topography affected the downward motion and blocking of Asian dust in China. The Asian dust transported from the dust source regions was deposited by fallout and rain-out with a reinforcing frontogenesis within a surface cyclone, as determined from satellite images using TOMS and GMS5. Accordingly, these results emphasize the importance of forecasting jet streaks, the IPV, and isentropes with geopotential heights in east Asia.

  • A neonate born at 38 gestational weeks was admitted due to generalized tonic-clonic seizure and cyanosis. The neonate was born six days previously at home through normal delivery and the umbilical cord was cut using scissors sterilized in boiling water. The neonate weighed 3,180 g at admission. Physical examination revealed cyanosis, opisthotonus, trismus and reactive muscle spasms. Laboratory exam, brain sonogram and EEG showed no significant abnormal findings. Based on her history and physical examination, the neonate was diagnosed with tetanus and put in an incubator isolated in a quiet, dark room. Treatment with tetanus human immunoglobulin along with antibiotics (penicillin G) were started immediately, and mechanical ventilation, administration of neuromuscular blocking agent and muscle relaxant were also started off. The frequency of seizure episode decreased gradually, and on the 32nd hospital day, mechanical ventilatory support was stopped along with extubation two days later. Thereafter, the neonate was in continuous generalized hypertonic state and showed feeding difficulty, but there was gradual improvement. She was dismissed on the 49th hospital day and is currently under OPD follow-up, doing well with no special problems. Respiratory management is critical to neonatal tetanus. We report here a case of tetanus treated with inhibition of self-respiration, neuromuscular blocker and application of ventilator, and present this method as a useful direction for future treatment of neonatal tetanus.

  • The purpose of this study is to examine the family reproduced by fishing village episode 1. (삼시세끼, three meals a day), which attempted a new type of entertainment termed an experiential real entertainment documentary, was produced in a total of nine episodes from October 2014 to March 2015. This study analyzed fishing village episode 1, which was aired in 2015 and obtained the highest ratings, using narrative analysis. The development of was consistently structured in the order of 'wake up - free time - breakfast - lunch - dinner - rest - sleep'. The character construction of the characters was created through the arrangement of a main space and a main role for each of the characters. Also, the characters were in relationships through which they became the background of each other. Therefore, in the family reproduced by , a mother without a father and a father without a mother are impossible. Despite that all the cast members were male, the subtitles constantly gave them the roles of 'housewife/wife/mother', 'father/husband/dad', and 'son', while actively blocking the image of a homosexual family. The family created as such was a family with children, a family with both mother and father, a heterosexual family, and a nuclear family. As a result, reproduced the typical modern family, normal family, and standard family.

  • Transported deposit was accumulated in a grit chamber built at the mouth of Yeocheoncheon in 1987 with the intention of blocking the influx of sediment into the Ulsan-harbor. This study attempted to analyze the effects of the transported deposit on the water quality at Yeocheoncheon. Only one episode of dredging has been performed in the approximately 25 years since the grit chamber were built, leading to the formation of stagnant water in the grit chamber due to a large amount of transported deposit. The deposit has a relatively high organic content, in the range of 11.7-25.9% (mean 18.3%). It appears that the main reason for the upstream transport of water pollution from the mouth of the Yeocheoncheon is the tides. The effects of organic content and stagnant water on water quality were analyzed using WASP. Moreover, the changes in water quality arising due to the removal of the grit chamber were analyzed. Results indicated that BOD improved by 18.8-100%, while T-P improved by 90.0-617.4%, between the grit chamber and Hanbi-Gyo, which is located 1.3 km away from the grit chamber.

  • Ameloblastic carcinoma is a malignant form of ameloblastoma defined by histological evidence of malignancy in primary, recurrent, or metastatic tumor. Such a tumor is rare, and the maxilla is an unusual site. Due to its rarity, the characteristics of this tumor in the maxilla have not been well described. Case 1: A 55-year-old, ill-appearing Nigerian male presented to our center with left maxillary swelling of seven-year duration. The swelling had been slow-growing and painless until one year prior, when the growth became rapid and was coupled with severe pain. The swelling affected both oral function and facial esthetics, and the patient reported difficulty breathing. There was a maxillary, ulcerated swelling extending from teeth 12 to 18 and blocking the left nostril. The involved teeth were moderately mobile. Case 2: A 32-year-old male farmer presented with recurrent right maxillary swelling of six-year duration. Prior to this episode, he had undergone surgery for ameloblastoma (follicular type). The present swelling was fungating through the skin and protruding into the right nostril. Ameloblastic carcinoma is an aggressive odontogenic tumor that requires aggressive surgical treatment.
