중화권 여우커를 위한 한국관광지 스토리텔링 고찰

왕옥지(Wang Ok Ji)(王玉枝) 대한중국학회 2016 중국학 Vol.55 No.-

본고에서는 중화권 여우커를 위한 한국관광지 스토리텔링에 대하여 살펴보므로, 이 방면연구에 보탬이 되고자 한다. 특정 관광지를 스토리텔링 하는 것은 더없이 좋은 관광안내인 것은 틀림없지만, 지나치게 허구적이고 흥미 위주의 스토리텔링은 관광객의 마음을 불편하게 할 수 있다는 점에서 심중해야 한다. 중국인의 습성 상 좋아하는 스토리텔링을 만들어내는 것도 좋지만, 보다 ‘한국적인 것’을 살려 스토리텔링을 담아 관광지를 개발하고, 중국 여우커의 마음으로 다가가는 것이 바람직하지 않을까 생각한다. In 2001, Chinese youke(482,227) visited Korea to overtake the American tourists(426,817), In 2013, China(4,326,869) has finally to overtake Japan(2,747,750), China has become the largest visit country visit to South Korea. Chinese youke of visited Korea in 2014 has amounted to 6 million people, Chinese youke is 2.7 times that of Japanese tourists. if including all the local Chinese youke in Taiwan, Hong Kong, Macao, it amounted to a total of 7 million people. In 2013, Japanese tourists visiting Korea was decreased, although more than 700,000 people was reduced more than in 2012(3,518,792), but foreign tourists(12,175,550) visited South Korea in 2013 rather than in 2012(11,140,028) increased by 9.3%. this is because Chinese youke visited Korea significantly higher than in 2012(2,836,892). In this paper, conducted a study about Korea Attractions storytelling for Greater China youke. In areas other than Seoul, using local resources and to make the storytelling. Jeju Island, Namhae, Geoje, the Busan there is a legend associated with the First Qin Emperor, Bu-lao-cao, Xu-Fu, San-shen-shan in the Chinese legend. Korea’s summer mount Kum-gang, mount Ji-ri, mount Ha-lla is considered to a ‘Underwater San-shen-shan’, Peng-lai-shan, Fang-zhang-shan, Ying-zhou-shan in the Chinese legend. Besides, There are many mountains with names like Peng-lai-shan, Fang-zhang-shan, Ying-zhou-shan in the Korea. Finally, China’s legendary story and Nam-hae China Ming Deng-Zi-long transcription story can feel the interest to Chinese youke. However, if too much unrealistic, the story will have the inconvenience to Chinese youke.

왕지원,김경민,강대중,강국희,정재록 성균관대학교 생명과학자원연구소 1995 生命資源科學硏究 Vol.2 No.1

Bifidobacterium angulatum KCTC3236 showed the highest α-galactosidase activity among the tested strains of Bifidobacteria( data not shown). Optimum culture conditions for the maximum production of α-galactosidase were as follows. The culture media was MRS broth containing 1% galactose as a carbon source and its initial pH was 7.0. The incubation temperature and time were 37℃, 21 hours respectively. Melibiose have been used as substrate. The formation of oligosaccharides was maximum at 40℃ when the substrate concentration was 30%. And the unit of α-galactosidase was 40 unit. Finally, we could observe the maximum production of oligosaccharides after 14 hours' enzyme reaction.

Random Amplified Polymorphic DNAs (RAPD) has been applied to the identification of human intestinal anaerobic Bifidobacteria. Recently, The RAPD technique has been used to analyse DNA polymorphism of genomic DNA from eukaryotes such as plants and animals(1, 3, 4, 10, 11). But there were only several reports on the polymorphism of prokaryotic genomic DNA by using this method(2,7). Total 100 random sequence primers were used in screening of species-specific primer. The oligonucleotide primers were ten bases long and designed to have average G+C contents of 60 mol %. Eight species of Bifidobacteria from human feces were selected. According to conventional method genornic DNA were extracted from each bifidobacterium and then RAPD-PCR was performed. Four primers have produced distinct electrophoretic band patterns, RAPD markers. Especially arbitrary primer # 101 showed species-specific DNA polymorphism for each of Bifidobacterial genomic DNA tested. The arbitrary primer # 101 showed good reproducibility when the PCR conditions were optimized. And also primer # 156, # 174, # 183, have produced amplified PCR products but not for all of the strains tested. Better DNA polymorphism was observed when two arbitrary primers were used in combination.

The purpose of this research is to analyze relationships among the habitual life, stress, and constipation and to help prevent and improve the constipation among women's university students. This is a descriptive interrelated research that has targeted women's university students. The data had been collected for 10 days, from December 22, 2003 to December 31, 2003. The survey was carried out to the 295 women's university students that had been randomly selected by visiting four-year-course colleges and universities in Seoul. The survey consists of 78 questions: five questions on the general trait, 11 questions on the habitual life, 51 questions on the stress, and 11 questions on the constipation. There are seven questions on the dietary life, four questions on exercising, and Shin Jung Ran's survey(2003) and Lee Ji Jung's survey(2001) was used as a reference. Yoon Ho Yul's five grade stress barometer(1996) was also used to measure the amount of stress. The collected data was analyzed by a real number, percentage, the arithmetical mean, the standard deviation, t-test, x²test using SPSS 10.00 for Windows Program. Results are as follow 1. Four to six cups of daily water intake was the highest by 50.0%. Students not have breakfast(55.7%) mostly because they did not have enough time(62.6%). Dinner was the most overeated meal by 72.3% and the most preferred food was meat by 42.0%. In the questions related to exercising, more than half of the students answered that they hardly do not exercise(58%), work out for less than 30minutes(67.3%), and exercised lightly(75.3%). 2. Students were suffering from stresses due to the personal relations(51.36±14.0426), scholastic achievement and personal direction(24.93±8.3037), financial conditions and family matters(20.28±8.1718) and social circumstances(2.7262). 3. In the defection part, the student's reply that they have more than five times of bowel movement on a weekly basis(48.3%), and that it takes three to five minutes to defecate(41.3%) were the highest. More than half of the students answered that their one time excrement quantity was between 30 grams to 60 grams(72.3%) and that it was normal(68.7%). In a question asking how it feels after the defecation(students were allowed to choose more than one answer), relieved and refreshed was the highest by 66.6%, an uncomfortable followed by 42.8%. 4.4% of the students answered that they suffer from strong abdominal pain during the defecation. The rest of the students answered that they do not have stomachache or that it was normal. The students were classified into the constipation group of 103 people(34.9%) and the normal group of 192 people(65.1%) under the devised definition of this research. 4. Students that live in dormitories and do their own cooking were more likely to have constipation than those that live in private residence or in a lodgins. 5. The research showed that there is a mutual relation between water in a day intake and the constipation. It means that the lesser water students drink, the more they suffer from the constipation. The number of times a student had a meal everyday and the constipation was interrelated. If a student had lesser or irregular meals in a day, they had more constipation. Preferred food and constipation was also interrelated. Students that preferred vegetable, fruit, and dairy products were more likely to belong in a normal/general group. 6. By dividing the stress factors into the lower categories, we were able to see that the total stress(t-2.063, p-0.040), personal relations(t-2.316, p-0.021), scholastic achievements and personal directions(t-20127, p-0.034) had mutual relation with the constipation. The constipation group(120.27±30.2708) was suffering from stronger level of stress than the normal group(112.97±28.1466). Through this study, we were able to verify that the few general traits, habitual life, and stress of the women's university students have mutual relations with the constipation.

난소절제후 Estrogen을 투여한 흰쥐 대동맥에서 Protein Kinase C-α와 Fas 발현의 변화

이왕수,이상엽,안지현,송영빈,김학진,이광재,유재격,김상욱,김태호,김치정,류왕성 중앙대학교 의과대학 의과학연구소 2001 中央醫大誌 Vol.26 No.3

Estrogen is believed to decrease coronary artery disease. Protein kinase C-α(PKCα)appear to be important in signal conduction pathways. Estrogen treatment increases catalytic activity of PKCα,and activation of PKCαcan modulate estrogen receptor levels and responsiveness. And it was reported that activation of PKC can protect cells from apoptosis induced by Fas ligation. But the beneficial effect of estrogen on PKCαwas not clearly demonstrated. The objective of this study was to evaluate the role of PKCαafter ovariectomy and estrogen therapy in rat aorta. The results were summarized as below: 1. The significant pathological changes were not observed in the rat aorta irrelevant to ovariectomy and estrogen therapy. 2. The expression of Fas was decreased in the aorta of estrogen-treated rats than that of ovariectomized rats without estrogen therapy. 3. Increased expression of PKCαwas more marked in the aprta of estrogen-treated rats than that of ovariectomized rat without estrogen therapy. In conclusion,PKCαmay be important in signal conduation pathway on the effect of estrogen. Activation of PKCαby estrogen reduced Fas expression, suggesting that PKCαactivation may play a role in protection against atherasclerosis. Further studies are needed to elucidate the role of PKCαafter estrogen therapy.

비아그라??복용 후 발생한 급성 심근경색증

Erectile dysfunction(ED) is defined as the inability to achieve and/or maintain an erection which is sufficient for satisfactory sexual activity. Risk factors for ED include many of the same risk factors for cardiovascular disease: hypertension; lipid abnormalities, including low high-density lipoprotein cholesterol; diabetes; and smoking. Therefore, some patients with ED will have ischemic heart disease. Viagra□, an oral therapy for ED, is the citrate salt of sildenafil, a selective inhibitor of cyclic guanosine monophosphate(cOMP)-specific phosphodiesterase 5(PDE5). The adverse effects of sildenafil include headache, flushing, dyspepsia, nasal congestion, visual disturbance, and cardiovascular complications. A general impression exists that cardiovascular complications of sildenafil occur mainly when the drug is taken concomitantly with nitrate. We report the case of a 52-year-old man who developed an acute myocardial infarction shortly after taking one tablet of sildenafil without sexual activity. The patient had not been using nitrates. Physicians treating patients with chest pain should be aware of the potential consequences of giving nitrates to patients taking sildenafil. We suggest that before initiating therapy, the history of sildenafil ingestion be obtained from patients with suspected myocardial infarction.

본 연구가 VRSA에 대한 신규 항생물질 생산 균주를 얻기 위하여 실시하였다. 국내외에 채취한 토양시료에서 분리한 방선균 중, 임상분리 VRSA와 돌연변이 유발 VRSA에 대해 항균성을 나타내는 JY-24를 선별하였다. 선발 균주는 원통형의 포자 모양을 갖고 있으며, Bennett's 배지에 배양시 aerial mycelium color는 흰색을 나타냈으며, reverse side color는 대체로 노란색을 나타내었다. 항균물질 생산을 위한 탄소원으로는 fructose, mannose, 질소원으로는 yeast extract가 가장 우수하였으며 glucose의 첨가로 항균 물질 생산성이 증가하는 것으로 나타났다. 최적 초기 pH는 pH 7로 나타났으며, 28 ℃, 37℃, 45 ℃의 온도에서 균이 성장하는 것으로 나타났다. 또한 배양기간에 따라 항균물질 생산성을 조사한 결과, 임상분리 균주에 대해 5일 배양 시 가장 높았으나, 3일 배양과 7일 배양 시 동일한 생산성을 나타내 생산속도가 빠르며, 안정한 물질인 것이 파악되었다. 향후 균주동정 및 항균물질 정제에 관한 연구를 수행하고자 한다. An antibiotic substance producing strain JY-24, effective to the VRSA (Vancomycin-resistant Staphylococcus aureus), was isolated from soil. The spore chain of JY-24 was cylindrical, and its sulface was smooth. The aerial mass color of the strain was white, and its reverse side color was yellow. The strain did not produce soluble pigment. For the production antibiotics, fructose, mannose and yeast extract were favorable as carbon and nitrogen sources. Optimal initial pH for the production of the antibiotic was pH 7. Accumulation of the antibiotic in the culture broth reached at maximal level after 5 days cultivation in Bennett's medium.

LAL method for the determination of Gram-negative bacterial Lipopolysaccharides(LPS) in milk is proposed and its value for bacteriological quality control is investigated. The relationship between the LPS contents and total colony count(cfu/ml), which covers the Gram-negative bacteria, was determined in raw milk samples. The coefficient of correlation between Gram-negative bacterial counts(cfu/ml) and LPS contents was r^2 =0.969. And, the correlation coefficient between total bacterial counts(cfu/ml) and LPS contents was r^2 =0. 914. It was also investigated how much the LPS contents were in UHT milks from l0 different dairy industrial companies in Korea. It varied from 92 ng LPS/ml to 938 ng LPS /ml.
