全北地域의 人口의 長期 豫測 : A modle of Chonbuk
徐東均,朴正根 全北大學校 1990 論文集 Vol.32 No.-
In this paper the population of Chonbuk province is projected by the survival method. The population projection is the essential factor to establish the long-run developing plan for regional economy. The accuracy of the estimated population is required to accomplish the developing plan efficiently. The estimated population (1990-2001) will be 2,172,015(1990),2,169,948(1995) and 2,247,593(2001) respectively. In the characteristics of population structure, the portions of the young age(0―14) and the old age(60―) to the total population will be over 23% and 13% in 2001. The population structure of Chonbuk will change to the types of the developed country step by step. When the decrease of the young age group and the increase of the old age group are anticipated, the welfare plan for the old age will be gradually required. The rapid decrease of Meon-level population results in the lack of labor forces in rural area. The counterplan to it should be considerated.

Dislocation is one of the serious complications in total hip replacement arthroplasties. The purpose of this study is to evaluate the risk factors of dislocation, including age, sex, preoperative diagnosis and bilaterality, history of previous hip surgery, positioning of component, soft tissue tension, treatment after dislocation or redislocation. Authors reviewed 190 patients of total hip replacement arthroplasty, which were performed from Jan. 1990 to Dec. 1996. 15 cases developed dislocation after surgery. Incidence of dislocation was 7.89%(15 of 190 cases). Dislocation after revision was not happened(0 of 18 cases). Inclination of acetabular cup was average 37.5° (range: 31° - 43° ). Average anteversion of the acetabular component was 18.1" by Woo and Morrey method, 11.4° by Hassan method. They were normal range except 3 cases. Dislocation was not prevented even though inclination and anteversion of acetabular cup were within normal range. Soft tissue tension is determined by change of limb and femoral neck length. Average limb length difference was -0.2mm(range; -l0mm - +10mm) and average offset difference was +1.7mm(range;-4mm - +18mm). Revision must be accomplished as soon as possible when limb shortening happen by upward migration of the acetabular component. In conclusion, anteversion of acetabular cup may be most important factor in our cases, so cup position must be fixed in proper position during operation.
輸入開放에 對應한 中長期 全北地域 農業政策方向에 關한 硏究
朴正根,徐東均 全北大學校 1992 論文集 Vol.34 No.-
This paper attempts to analyze the direction of agricultural polices of Chonbuk region in the trade liberalization and to suggest an alternative regional policy of agricultural development in Chonbuk province. The increasing pressure of agricultural import liberalization from abroad has given great burden to Chonbuk agricultural sector which has lagged behind the average growth of national agriculture. The charactersitics of Chonbuk agriculture can be summarized as wide-spread small scale farming, greater portion of old-aged labor and rice monoculture system. However, the agricultural production sector of Chonbuk becomes more and more commercialized and the consumption patterns of agricultural products become diversified and high-quality oriented continuously. The present situation of Chonbuk agricultural is in a vulnerable state to those changes. Divergent measures in Chonbuk agriculture are urgently requested for the improvement of present production structure. Among these, the increase of Chonbuk local government investment for various in infra-structure of agricultural facilitis should be carried out in such a way that agricultural productivies can be enhansed. Furthermore, it is also important to emphasize on fostering specific activities that develops an appropriate technologies induced by changes of resource endowments.

A total of 28 Salmonella enterica serovar Typhimurium isolated from diseased pigs and swine carcasses between 2001 and 2003 were characterized by the antimicrobial resistance profiles, PCR for detection of S. Typhimurium DT104 and pulsed-field gel electrophoresis (PFGE) with the restriction enzyme XbaI. All but one isolate presented multidrug resistance (MDR) to more than two antibiotics tested. A total of 11 resistance profiles were observed, and two phenotypes, ST and ASSuTG, were the most common among them. Two isolates were found to be S. Typhimurium DT104 isolates by PCR, and their resistance profile did not show the DT104 typical resistance type ACSSuT, but ACSSuTGK instead. PFGE identified 11 banding patterns in dendrogram, and three main clusters (designated A to C) were represented. Interestingly, sixteen of 19 S. Typhimurium isolates belonging to cluster B showed an identical band pattern.

Swine dysentery caused by Brachyspira hyodysenteriae, an anaerobic, beta-hemolytic spirochete, is a severe mucohemorrhagic diarrheal disease that primarily affects pigs during the growing and finishing period. The current standard laboratory procedure to culture and identify B hyodysenteriae takes 3 to 7 days. This report present a rapid PCR for detection B hyodysenteriae in a single reaction using DNA from swine intestinal samples. The PCR produced a specific 421bp PCR product with template DNA purified from B hyodysenteriae, and the accuracy for detection of B hyodysenteriae by PCR results compared with those of conventional method was 100% in intestinal specimens. Nonspecific bands were not detected with B innocens, a nonpathogenic common inhabitant spirochete, including other enteric bacterial organisms. This procedure could detect as little as 50 pg of template DNA for B hyodysenteriae.

A total of 22 Salmonella enterica serotype Enteritidis (S. Enteritidis) isolates from human and chicken sources were analyzed by pulsed field gel electrophoresis (PFGE) using XbaI restriction enzyme to assess the genetic relationships between strains from different sources. PFGE permitted the resolution of XbaI restriction fragments of the 22 S. Enteritidis into 6 distinct PFGE types (PFT), designated PFT1 to PFT6, and 2 subtypes within PFT2 and allowed to detect between 9 and 10 bands with fragments sizes in the range of 25~635 kb. Four of twelve isolates from human showed an identical PFGE patterns with 2 isolates from chickens. Also, another one isolate from human showed an identical PFGE patterns with other 5 isolates from chickens. Only one isolate from chicken, however, showed a different pattern compared to other PFTs. These results suggested that sporadic human food-poisoning cases infections caused by S. Enteritidis in this study were due to the consumption of contaminated chicken meats and that a clonally highly similar strains exist and spread between human and chicken sources.

The purpose of this study is to determine the prevalence of Brachyspira hyodysenteriae from 43 swine farms with diarrhea or a history of diarrhea in Gyeongbuk province by PCR. The overall herd prevalence of B hyodysenteriae was 37.2%(16/43), and the average prevalence of B hyodysenteriae among all sampled pigs was 10.8%(50/462). Positive herds for B hyodysenteriae were distributed throughout Gyeongbuk province from 14.3~50%. Herd size had a effect on the frequency of B hyodysenteriae. The frequency of B hyodysenteriae in herds with less than 1,000 pigs was 47.4%, that of herds between 1,001 and 2,000 pigs was 41.7%. Also, the frequency of B hyodysenteriae in herds with more than 2,000 pigs was 16.7%.
