There showed that Seochulji has 153 taxa, 133 taxa of Jeongjaji, and 126 taxa of Yeondang. Planting species are 44 taxa, and most of them were planted around reservoirs and buildings. The rare plants were 3 taxa including Aristolochia contorta, Ottelia alismoides, and Sparganium stoloniferum, and there were no specific threats. The hydrophytes were 39 taxa including 28 taxa of emergent plants, 4 taxa of floating-leaved plants and submerged plants each, and 3 taxa of free floating plants. The invasive alien plants were 46 taxa, and the ecosystem disturbing species were 5 taxa including Rumex acetosella, Ambrosia artemisiifolia, Lactuca seriola, Symphyotrichum pilosum, and Humulus scandens.

Pigmented Basal Cell Carcinoma of the Nipple-Areola Complex in an Elderly Woman

정한진,전재훈,김호연,이석종,김도원,이원주,정진향 대한피부과학회 2011 Annals of Dermatology Vol.23 No.-

Basal cell carcinoma (BCC), which frequently occurs in sun-exposed areas of the head and neck region, is the most common cutaneous malignancy. The nipple-areola complex (NAC) is an uncommon site for BCC to develop. BCCs in this region display more aggressive behavior and a greater potential to spread than when found in other anatomical sites. This paper outlines the case of 67-year-old female with a solitary asymptomatic black plaque on the right areola. The lesion was initially recognized as Paget’s disease of the nipple by a general surgeon. However, the histopathological features showed a tumor mass of basaloid cells, a peripheral palisading arrangement and scattered pigment granules. Finally, the patient was diagnosed with pigmented BCC of the NAC and was referred to the department of dermatology. Positron emission tomography-computed tomography revealed the absence of distant metastasis. A wide excision was done. The lesion resolved without recurrence or metastasis during 14 months of follow-up. (Ann Dermatol 23(S2) S201∼S204, 2011)

Background and Objectives Laryngopharyngeal reflux (LPR) is a prevalent condition with an increasing incidence, and several recent studies have reported the association of LPR with chronic rhinosinusitis (CRS). In this study, we studied the effect of proton-pump inhibitors (PPIs) on symptom improvement for LPR and comorbid CRS. Subjects and Method Enrolled in the study from January 2017 to December 2017 were 164 patients (54 male, 110 female, mean age 48.8 years) who were diagnosed as LPR by reflux symptom index (RSI) or reflux finding scores (RFS) and comorbid CRS. Sino-Nasal Outcome Test (SNOT)-20 and Lund-Kennedy endoscopic scores were evaluated for CRS severity. The study group was divided into PPI treatment group (Ilaprazole 20 mg, once a day for 8 weeks) and non-treatment group. The RSI, RFS, SNOT-20, and Lund-Kennedy endoscopic scores were repeated at the end of treatment. Results Ninety-two patients were prescribed PPI and 72 patients were not. Initial RSI, RFS, SNOT-20, and Lund-Kennedy score did not differ between the two groups. RSI and RFS decreased significantly after eight weeks of PPI medication (p=0.002 and p<0.001, respectively). In the non-treatment group, only RFS showed statistically significant decrease. SNOT-20 and Lund-Kennedy endoscopic scores decreased significantly in the treatment group (p=0.005 and p<0.001, respectively) compared to the non-treatment group. Conclusion The results of our study suggest that PPI treatment for 8 weeks was effective in reducing signs and symptoms of both LPR and CRS.

내이 기형 환아에서 와우이식 후 반복적으로 발생한 뇌막염 1예

Cochlear implantation (CI) has been regarded as a safe and effective treatment for patients with severe to profound sensorineural hearing loss. The increase of experience in CI thus has had the effect of leading more children with inner ear anomaly to be considered as cochlear implant candidates. For patients with inner ear anomaly, auditory rehabilitation has been reported to be improved after CI; however, there are several factors such as cerebrospinal fluid leakage, facial nerve injury and abnormal positioning of electrode during surgery and uncertainty of auditory rehabilitation and possibility of the recurrent meningitis after CI that should be considered. Several studies proved that the incidence of otogenic meningitis is higher in patients with inner ear anomaly than in patients with normal inner ear anatomy. We experienced a case of recurrent meningitis due to an unusual cause after cochlear implantation in a patient with inner ear anomaly.

Genetic and morphological divergence of Euphorbia esula and E. maackii in Korea (Euphorbiaceae)

정한진,박기룡 한국식물분류학회 2012 식물 분류학회지 Vol.42 No.4

To understand morphological and genetic differentiation between Euphorbia esula and E. maackii we examined 12 morphological characters and 11 isozyme loci from 14 populations of two species. Species of E. esula complex (A = 1.63, P = 44.83, He = 0.198) in Korea maintain nearly as high as the genetic diversity reported in East Asian E. jolkinii and E. fauriei while lower than those of E. ebracteolata and E. pekinensis in Korea. Although the ranges of most morphological character variation of the two species overlap, E. esula and E. maackii were well recognized by the combination of the morphological traits, and the result of UPGMA phenogram supports the two distinct species inhibited in Korea. However, isozyme data do not support the recognition of E. esula and E. maackii. The discordance between morphological and allozyme data should be explained by the recent divergence or gene flow via introgressive hybridization between two species.

Preparation of polyurethane microcapsule using prepolymer with azido functional group

정한진,이경진 한국공업화학회 2020 한국공업화학회 연구논문 초록집 Vol.2020 No.-

Azide functional group can easily click reaction with alkyne group. So we synthesized azido-polyurethane(azido-PU) prepolymer with an isocyanate group at the end group using poly(GAP-co-THF)diol and MDI. The prepolymer reacted with 1,4-butanediol or glycerol as polyol and is used as a microcapsule shell compound. Azido-PU microcapsules were prepared via the interfacial polymerization method at oil in water emulsion. The microcapsule core materials consist of IPDI and chlorobenzene. We will click reaction on the azide group on the surface of the microcapsule and solvatochromic dye with alkyne group and then observe the color change of the solvatochromic dye on the surface when the microcapsule breaks and the core material release.
