Kim, Won-Bo 1998. An Optimality-Theoretic Approach to Korean and English Consonant Cluster Simplification. Studies in Phonetics Phonology and Morphology 4, 109-124. The purpose of this paper is to show how consonant cluster simplification of both standard Korean and Kyengsang dialect as well as of English can be explained in a unified manner under Optimality Theory. To do so, we propose a new constraint, Spontaneous Voice Constraint, which uses manner feature of articulation, and attempt to account for consonant cluster simplification of Korean and English with the newly proposed constraint plus several other existing constraints under Optimality Theory.(Cheju National University)

Won-bo Kim 한국음운론학회 2000 음성·음운·형태론 연구 Vol.6 No.1

Kim, Won-boo 2000. Verbal Conjugation and Glide Formation in Cheju Dialect. Studies in Phonetics, Phonology and Morphology 6.1, 59-74. This paper deals with both glide formation and insertion to resolve a vowel hiatus within the framework of Optimality Theory when verbs conjugate in Cheju dialect. In this paper, two crucial constraints Onset and OCP are used in addition to the constraints MAX-IO/MAX-OO, MAX(??)-IO/MAX (??)-00 and DEP. IO/DEP-OO. It is shown that vowel hiatus resolution takes place in not only input-to-output correspondence but also output-to-output correspondence, which requires the higher-ranked constraint Struc (б).

Lee, Kyeong Soo,Kim, Chang Suk,Park, Jong Heon,Hwang, Tae Yoon,Kim, Sang Won,Sim, Sung Bo,Lee, Kun Sei The Korean Society for Thoracic and Cardiovascular 2016 The Korean Journal of Thoracic and Cardiovascular Vol.49 No.sup

Background: The purpose of this study was to investigate longitudinal changes of the utilization of operational and surgical medical care inside and outside a metropolitan area over 10 years, analyzing the residential areas of patients and the locations of medical facilities for major cardiovascular surgery. Methods: Data analysis was conducted by classifying the addresses of patients and the locations of medical care facilities of metropolitan cities and provinces, using data from the National Health Insurance Corporation from January 2003 to December 2013. Results: There is serious concentration of major heart surgery to medical facilities in Seoul; this problem has not improved over time. There were differences in percentages of surgical procedures performed in the metropolitan areas according to major diseases. In the case of Busan and Daegu provinces, at least 50% of the patients underwent surgery in medical facilities in the city, but there are other regions where the percentage is less than 50%. In the case of provinces, the percentage of surgical procedures performed in medical facilities in Seoul or nearby metropolitan cities is very high. Conclusion: Policies to strengthen the regional capabilities of heart surgery and to secure human resources are required to mitigate the concentration of patients in the capital area. Many regional multi-centers must be designated to minimize unnecessary competition among regional university hospitals and activate a win-win partnership model for medical services.

Background: Histamine in food is known to cause food poisoning and allergic reactions. We usually ingest histamine in cooked food, but there are few studies about the influence of cooking method on the histamine level. Objective: The purpose of this study was to determine the influence of cooking methods on the concentration of histamine in foods. Methods: The foods chosen were those kinds consumed frequently and cooked by grilling, boiling, and frying. The histamine level of the food was measured using enzyme-linked immunosorbent assay. Results: Grilled seafood had higher histamine levels than raw or boiled seafood. For meat, grilling increased the histamine level, whereas boiling decreased it. For eggs, there was not much difference in histamine level according to cooking method. Fried vegetables had higher histamine levels than raw vegetables. And fermented foods didn’t show much difference in histamine level after being boiled. Conclusion: The histamine level in food has changed according to the cooking method used to prepare it. Frying and grilling increased histamine level in foods, whereas boiling had little influence or even decreased it. The boiling method might be helpful to control the effect of histamine in histamine-sensitive or susceptible patients, compared with frying and grilling. (Ann Dermatol 29(6) 706∼714, 2017)

The majority of strokes are caused by ischemia and result in brain tissue damage, leading to problems of the central nervous system including hemiparesis, dysfunction of language and consciousness, and dysfunction of perception. The purpose of this study was to investigate the effects of Poly(ADP-ribose) polymerase(PARP) on necrosis in neuronal cells that have undergone needle electrode electrical stimulation(NEES) prior to induction of ischemia. Ischemia was induced in male SD rats(body weight 300g) by occlusion of the common carotid artery for 5 min, after which the blood was reperfused. After induction of brain ischemia, NEES was applied to Zusanli(ST 36), at 12, 24 and 48 hours. Protein expression was investigated using immuno-reactive cells, which react to PARP antibodies in cerebral nerve cells, and Western blotting. The results were as follows: In the cerebral cortex, the number of PARP reactive cells after 24 hours significantly decreased(p<.05) in the NEES group compared to the GI group. PARP expression after 24 hours significantly decreased(p<.05) in the NEES group compared to the GI group. As a result, NEES showed the greatest effect on necrosis-related PARP immuno-reactive cells 24 hours after ischemia, indicating necrosis inhibition, blocking of neural cell death, and protection of neural cells. Based on the results of this study, NEES can be an effective method of treating dysfunction and improving function of neuronal cells in brain damage caused by ischemia.

( Bo Ri Kim ),( Minsu Kim ),( Chong Won Choi ),( Soyun Cho ),( Sang Woong Youn ) 대한피부과학회 2020 Annals of Dermatology Vol.32 No.4

Background: The clinical features of inflammatory papular dermatoses of the face are very similar. Their clinical manifestations have been described on the basis of a small number of case reports and are not specific. Objective: This study aimed to use computer-aided image analysis (CAIA) to compare the clinical features and parameters of inflammatory papular dermatoses of the face and to develop a formalized diagnostic algorithm based on the significant findings. Methods: The study included clinicopathologically confirmed inflammatory papular dermatoses of the face: 8 cases of eosinophilic pustular folliculitis (EPF), 13 of granulomatous periorificial dermatitis-lupus miliaris disseminatus faciei (GPD-LMDF) complex, 41 of granulomatous rosacea- papulopustular rosacea complex (GR-PPR) complex, and 4 of folliculitis. Clinical features were evaluated, and area density of papular lesions was quantitatively measured with CAIA. Based on these variables, we developed a predictive model for differential diagnosis using classification and regression tree analysis. Results: The EPF group showed lesion asymmetry and annular clusters of papules in all cases. The GPD-LMDF complex group had significantly higher periocular density. The GR-PPR complex group showed a higher area density of unilateral cheek papules and the highest total area density. According to the predictive model, 3 variables were used for differential diagnosis of the 4 disease groups, and each group was diagnosed with a predicted probability of 67%∼100%. Conclusion: We statistically confirmed the distinct clinical features of inflammatory papular dermatoses of the face and proposed a diagnostic algorithm for clinical diagnosis.
