김승곤,최성민 서울保健大學 1994 論文集 Vol.14 No.1

This study was undertaken the biochemical characteristics, serotyping and antibiotics susceptibility to 79 strans of Escherichia coli isolated from patient from march in 1993 to December in 1993. Of 79 isolates, thirty one isolates(39.2%) were idenfied by pathogenic E. coli immune sera producted by Denka Seiken. Among them, 9 isolates(11.4%) were 06, followed by 015 and 044(4 isolates, 12.9%), respectively. 018, 0114, 0119, 0125, 0146, 0153 and 0164 were identified 1 isolate(3.2%), repectively. Resistance rate of E. coli isolated from patients against 12 antibiotics were 86.1%(68 isolates). Of them, resistance rate against TC was 68.3%(54 isolates), AM 64.4%(51 isolates), CB 62.0%(49 isolates), NN and NA 8.9%(7 isolates) and PB 1.3%(1 isolate), respectively. Of 68 resistant isolates, 59 isolates(86.8%) were resistant to more than 2 drug, followed by 2 drugs-resistance pattern01 isolates, 16.2%), 3 drug and 6 drig resistance pattern(9 isolates, 13.2%). Of multipleresistance pattern, AM-CB-SM and AM-CB-SM-TE pattern were most frequent(5 isolates, 7.4%, respectively) and more than 10 drugs resistance pattern was 1 isolate. Of 68 resistant isolates, 42(61.8%) were transferred their resistance to recipient cell (E. coli ML1410Na^(r)), Of them, the most frequently multiple transferred drugs was 2 drugs(40.5%, 17isolates) and the most frequently multiple transferred pattren was AM-CB(23.8%. 10 isolates).

In this study, we measured the activity of the erythrocyte pyrimidin 5'-nuclectidase(P5N) and urinary N-acetyl-β-D-glucosaminidase(NAG) from 154 workers exposed to lead and 43 workers not exposed. We analyzed the correlation of the P5N activity and NAG activity with other biololgical exposure indices of lead such as blood lead(PbB) and zinc protoporphyrin(ZPP). The measurement was performed by using high performance liquid chromatography(HPLC), spectrophotometer and atomic absorption spectrophotometer. The results are as follows : 1. The mean value of P5N activity for workers exposed to lead was 9.50±3.13 μmol uridine/hr/g Hb and 11.60±2.2 μmol uridine/hr/g Hb for workers not exposed. The P5N activity showed a normal distribution, but the other indices of lead showed logarithmic normal distributions. 2. The P5N activity and ZPP were decreased as PbB was increased. But the NAG activity had no correlation with changes of PbB. 3. The correlation coefficients of the P5N activity with other biological exposure indices of lead such as PbB, ZPP, NAG activity were -0.72, -0.55, and 0.05, respectively. We speculated that the P5N activity can be used as a reliable biological exposure index of lead but NAG activity can be used as a biological management index of lead.

부산 슬로투어리즘을 위한 제언 : 코로나19 팬더믹 위기와 국제관광도시 지정에 즈음하여

양승훈 신라대학교 부산학연구센터 2021 부산연구 Vol.19 No.1

본 연구는 부산광역시의 기반사업으로서 관광산업에 대한 제언이다. 최근 부산광역시는 코로나 19 팬더믹에 따른 관광산업 전반의 위기와 함께 시의 국제관광도시 지정에 따른 기회라는 모순된 상황에 접하고 있다. 따라서 향후 지속가능한 부산광역시의 관광산업을 위한 방안으로서 슬로투 어리즘을 제시하였다. 슬로투어리즘은 기존의 패스트투어리즘에 대비되는 관광으로서 전자가 새 로운 관광이라면 후자는 오래된 관광이라고 할수 있다. 슬로투어리즘은 찬찬천천히 보는 진짜관 광이다. 패스트투어리즘은 관광이라는 사회·문화현상에 대비하여 경제현상으로서 관광산업의 가치 극대화를 위해서 대량생산, 대량유통, 대량소비의 원칙에 충실한 반면 그 한계점을 드러내고 있 다. 따라서 선행연구를 바탕으로 부산 관광의 현황과 문제점을 짚어보고 왜 이 시점에서 슬로투 어리즘이 요구되는가의 당위성을 확보하였다. 슬로투어리즘을 느림, 작음 그리고 지속가능성으로 이루어진다는 전제하에서 부산이 이를 바탕으로 어떻게 슬로투어리즘을 구현해 나갈 것인가를 제 안하였다. 첫 번째는 관광과 생활의 통합을 통해 생활관광을 활성화하고 관광지와 관광매체를 통 합하여 지역 주민의 역량강화를 통해 지역민을 위한 지역민에 의한 지역민의 사회경제적 관광기 업 양성을 촉구하였다. 연구의 시사점과 한계점은 연구말미에 포함시켰다.

Schwann cells(SCs), an important component of the peripheral nervous system, intract with nerous to mutually support growth and replication for the peripheral nerve regentation. Recently, ading SCs to the lumen of guidance channel is widely tried to improve regeneration or to make regeneration possible over otherwise irreparable gaps. however, it is not easy to isolate and multiplicate SCs as much as enough to help the axonal regeneration. For the allogeneic SCs source for tubular nerve guidance, we developed a little bit improved technique of harvesting and multiplicating SCs. by culturing dispersed dorsal root ganglia in specially designed medium with growth factors and serial processing, we repeatedlly generate relatively homogenous SC cultures. Our technique was compared with other methods of literature using immunostaining methods such as GFAP, S100, BDNF and the total SC count assessment at different time interval after primary culture.

To find out the differences between periodontal ligament cells (PDL cells) and gingival fibroblast cells (GFB cells), alkaline phosphatase, a marker enzyme for osteoblast, was used to measure the activities and 45CaCl₂isotope was used to find out cellular and release of 45Ca, a requisite for bone formation, PDL cells and GFB cells from 1 to 5 passages were also measured in alkaline phosphatase activity assay. By the use of above methods, followings were concluded that the PDL cells and the GFB cells have characteristics that are different from each other. In that PDL cells showed large amount of calcium uptake ad large amount of calcium release in initial stage, they seem to possess characteristics which are similar to osteoblast-like cells. 1. The PDL cells, in contrast to the gingival fibroblast, showed exceedingly high alkaline phosphatase activity which was highest at the second passage, decreasing thereon. But gingival fibroblasts cells showed no distinct differences in alkaline phosphatase activity as the passage were elapsed. 2. For both PDL cells and GF cells, the 45Ca uptake was greatest at 2 hours period. The PDL cells showed higher measuring than GFB cells through out the whole time period. 3. Whereas the GFB cells showed slow increase of 45Ca release as time relapsed, the PDL cells showed rapid increase of 45Ca release.
