This study is to classify and evaluate the changes of policies, sizes, and the administrative organizations of parks in Seoul. Reviewed with the changes examined up to now, most plans were temporary ones established on situations. So it would be better to make mid-term plans based on long-term plans. For the present conditions of parks, it appeared that city parks should be managed not by entrusting autonomous districts but by Seoul local government having park administative offices by 5-green land areas, and that citizens should be allowed to develop and operate management programs for parks. For its organization, officials in the bureau consisting of specialized experts should be appointed as the directors for the concerned special duties. And the field of park, leisure, ecology and sightseeing, etc. scattered in Seoul City organizations are to be emerged onto a scholastic category. For and it is recommend to connect organizations and scientific research.

This study was carried out to examine the changes of pH, chlorophyll, chlorophyll patterns and ascorbic acid contents, and sensory evaluation in Oi-Kimchi by the different periods of storage. The contents of chlorophyll a and b were 52.2% and 14.44% at storage 0 days, 20.67% and 16.99% at storage 11 days, 0% at storage 14 days, and decreased with storage times increased. But, phephorbide a and b were increased with storage times increased until storage 11 days, and were 28.44% and 1.25% at storage 0 days, 42.63% and 15.79% at storage 11 days, 0% at storage 12, 14 days. The contents of ascorbic acid were increased until storage 4 days, but afterwards were decreased with storage times increased, and were 2.57㎎% at storage 0 days, 5.49㎎% and 2.95㎎% at storage 11 days, 0% at storage 14 days. Sensory evaluations of appearance, flavor, taste, texture, overall acceptability showed the highest at storage 8 days, and disliked after storage 10 days.

19세기 후반 독일사회의 사회문화에 대한 고찰

박근제 慶南大學校 人文科學硏究所 1998 人文論叢 Vol.11 No.-

<Zusamrnenfassung>Die deutsche Gesellschaft befand sich damals in einer Ubergangssituation in der zweiten Hälfte des 19. Jahrhunderts. In den funiziger Jahren schafft die wirtschaftliche Entwicklung eine völlig neue politische und soziale Situation. Die Gründe sind die Revolution von 1848, die industrielle Revolution und die Reichsgründung von 1871.Eisenbahnbau und Schwerindustrie sind zunachst die Häupttrager dieser industriellen Revolution. Außerdem rekrutieren sich billige Arbeitskräfte aus den niedergehenden Zweigen des Handworks, vor allem aber aus dem ostdeutschen Landarbeiterproletariat und strömen in die neuen Industriezentren. Und Aktiengesellschaften und Großbanken bringen das erforderliche Kapital auf.Seit den siebziger Jahren sah sich der landbesitzende Adel ökonomisch in die Defensive gedrangt. Aber der Adel stellte einen exklusiven Berufsstand dar und erfreute sich das gesellschaftlichen Ansehens als symbolischer Form der Macht, deren Lebens Denkstil des Adels ihren Einfluß auf die anderen Klassen ausubten Die Bourgeoisie, die ihren sozialen Aufstieg durch wirtschaftliche Erfolge errungen hatte, war eine machtige Gruppe. Die reichen Geldmittel. wu.rden nur zu materiellen Zwecken verwandert und das Ideele verkummerte. Der vierte Stand ist inzwischen immer starker angewachsen und hat sich nun zur größten sozialen Gruppe entwickelt. Allgemeines Klassenbewußtsein und Klassenßezogene Solidarität beginnen sich zu etablieren.Einerseits fürchten die Konservativen die Auflösung aller Grundlagen der bestehenden politischen und sozialen Ordnung. Sein Kampf gegen den Liberalismus ist zugleich ein Kämpf um die Bewahrung der alten Ordnung gegen die aufstrebende Macht des industriellen Bürgertums. Und die Konservativen kampfen gegen die Aufhebung der Standesschranken, gegen gleiches Wahlrecht und fur die Wiederherstellung der guts-und standesherrlichen, Rechte. Das deutsche konservative Kaiserreich ist nicht auf Veranderungen gerichtet, sondern auf die Bewahrungen der altpreufiischen Gesellschaftsordnung, die durch die Vorherrschaft des Junkertums gepragt ist.Andererseits beginnt sich das mit der Industrialisierung ständig wachsende Industrieproletariat schon bald in eigenständigen Organisationen zusammenzuschließen und sich auch politisch zu artikulieren. Die Sozialdemokratie zielt auf Veränderung des deutschen Nationalstaats im Sinne einer inneren Reform.Und im Kulturkampf gilt das Zentrum als Ultramontan und internationalistisch wegen seiner Verbindung zum Papsttum. Im Kulturkampf wird die Autonomie des Staates und der Politik gegen die katholisch-konfessionellen Interessen des Zentrums erbittert verteidigt. AuBerdem befurchtet Bismarck ein Zusammengehen des Katholizismus mit anderen oppositionellen Gruppen im Reich.

기업의 효율적인 정보시스템 구축은 정보화 사회에서는 반드시 필요하다.또한 기업의 성장 규모, 기업의 요구 사항, 기업의 보다 향상된 업무를 위해 시스템을 능동적으로 구현, 확장, 재구성되어야 한다.이에 정보의 연계, 최신 정보의 효율적 관리를 이용한 구체화와 정보화를 유지할 수 있다.이를 위하여 중소 업체에서는 한 번에 많은 투자를 해야되는 종합 정보화 시스템보다는 생산 관리, 인사 관리, 회계 관리 등 각각에 대한 정보화를 위해 가장 기본적인 프로그램들을 업체의 특성과 차별성을 고려하여 실용 업무에 보다 적합한 자동화 시스템구성의 필요성이 강조된다.따라서 이들 시스템간에 서로 정보를 교환하고, 의사결정을 하는 종합 관리 시스템을 구축하여야 하는데, 이를 위하여 기존에 개발된 영업관리, 생산 관리, 인사 관리, 회계관리 프로그램들을 통합하는 것이 새로운 시스템을 개발하는 것보다 경제적, 기능적 측면에서 매우 유리하다 할 것이다. 본 연구에서는 (주)두양금속의 기존에 사용중인 영업관리, 생산 관리, 인사 관리, 회계 관리 시스템을 통합하고자 이미 구축된 시스템을 분석하고 각각의 독립된 업무를 연계하여 효율적인 정보 관리 시스템을 구축하는 것에 목적을 두고있다.

Le-Fort I Osteotomy is considered by many surgeons to be a safe and predictable method for correcting various dentofacial deformities. However, there are controversial options concerning the stability of two-jaw surgery (Le-Fort I osteotomy and sagittal split ramus osteotomy) compared to single mandibular surgery (sagittal split ramus osteotomy). The purpose of this study was to evaluate the post-operative stability of mandible in two-jaw surgery and single mandibular surgery, to help the establishment of accurate treatment planning in patients with a skeletal class Ⅲ malocclusion. There were 15 patients who had been undergone two-jaw surgery and 20 patients who had been undergone single mandibular surgery. Lateral cephalograms of these 2groups ; Preoperation and immediate post-operation, postoperatively 1month, postoperatively 3months, at the latest follow up(>6months) ; were analyzed by linear measurement to evaluate changes in position (hard tissue B, Pogonion point) and compare repapse both group. The results obtained were as follows ; In view of B-point, the horizontal repapse rate of single mandibular surgery was 10.17% at post-op 1month, 12.52% at post-op 3months, 13.01% at post-op 6months and two-jaw surgery was 10.23% at post-op 1month, 11.84% at post-op 3months, 12.97% at post-op 1month, 11.33% at post-op 3months, 12.01% at post-op 6months in two-jaw surgery. In terms of vertical relapse rate, rates of B point were 22.96% at post-op 1month, 28.30% at post-op 3months, 29.56% at post-op 6months in single mandibular surgery and 21.14% at post-op 1month, 25.45% at post-op 3months, 28.86% at post-op 6months in two-jaw surgery. Those of Pogonion point were 26.63% at post-op 1month, 28.40% at post-op 3months, 29.29% at post-op 6months in single mandibular surgery and 20.20% at post-op 1month, 25.44% at post-op 3months, 27.68% at post-op 6months in two-jaw surgery. There were no statistical difference between single mandibular surgery and two-jaw surgery in mandibular stability.

We prospectively analyzed the corneal topography of 26 eyes in 26 patients who had undergone scleral expansion for correcting presbyopia. We examined 26 eyes of 26 patients which were devided into 2 groups (mean age: 51 years, range 40-60 years) according to type of scleral expansion band, with computerized corneal topographic analysis system. Preoperatively and 5 times postoperatively (1day, 1week, 2weeks, 1month, 2months), quantitative descriptors of corneal topograpgy such as Sim K (simulated keratometry value), SRI(surface regularity index), and SAI(surface asymmetry index) were measured at each visit. The mean follow-up period was 43 days. Sim K of the operative eyes ranged from 0 to 2.5 (mean, 0.93) before operation, and mean 2.24 at postoperative 1 day in group Ⅰ. In group Ⅱ, Sim K was mean 2.20 at postoperative 1 day and decreased thereafter. SRI was from 0.54 to 1.39 and SAI was from 0.09 to 0.45 before operation. After operation, mean SAI was maximum at postoperative 2 week and mean SRI was maximum at postoperative 1 day and decreased thereafter. After two months, it became minimum. This study demonstrates that quantitative topographic change after scleral expansion for correcting presbyopia were great during first 1 week after surgery but this change diminished thereafter. Further long studies are in progress to evaluate the long term effects of this procedure.

This laboratory study examined the impact of free chlorine residual and pipe material on the formation of biofilm in drinking water distribution pipe surfaces. Result of heterotrophic plate counts(HPC) of the biofilm in the tap water- supplied reactor averaged 2.17×105CFU/cm2 on PVC and 2.43×105CFU/cm2 on STS 316, respectively. HPCs on the surface exposed to the tap water containing 0.2mg/L of free chlorinne residual averaged 4.24×104CFU/cm2 on PVC and 6.54×104CFU/cm2 on STS 316, respectively Average of HPC/Total direct counts in the tap water-supplied reactor ranged from 1.08%(PVC) to 1.26%(STS 316) and from 0.38%(PVC) to 0.65%(STS 316) in the reactor supplemented with disinfectant, resfectively. No correlation was observed between disinfectant addition and biofilm density. With regard to the biofilm formation, little difference existed between PVC and STS 316. Yellow and red pigmented bacteria were the dominant expressions in bulk fluid, whereas non-pigmented bacteria were found dominant in the biofilm. Pink/red pigmented bacteria were found to be facultative anaerobic, while yellow pigmented bacteria and non-pigmented bacteria were found to be obligate aerobic.

This study is aimed at identifying the decision making criteria as B/C ratio, IRR and NPV based on the expected benefits and costs of the land utilization and promotion projects which have implemented to improve agricultural structure under WTO system. To carry out the objectives of the study, Sinseok project area located at Dangjin district, Chungnam province was selected. Sinseok project area has 306.2 ha of paddy area with 172 farm households. The project area will be operated by the 33 specialized farm households after completion of the project which will have 20 years of economic life. After completion of the project, farm size will be increased from 1.8ha to 9.3ha. Land intensity of the project area will be increased by 10%. Increase of land productivity and cost saving due to the labor saving technology as farm mechanization will be expected. According to the survey results, the annual amount of production cost savings per farm was estimated 3.884million won and increased total farm income was expected about 43.8million won per year. The total expexted project benefits was expected 174million won per year. The project costs to promote land utilization and structural change consisted of handling charges, and direct payment for land movility. The decision making criteria representing economic feasibility of the project such as B/C ratio, NPV and IRR were estimated 2.49, 483million won and 30% respectively when the cut-off rate was taken into account 10%. In conclusion, the land utilization and promotion project proppeled by the Korean Government under the agricultural land law is considered economically feasible from the view points of expected project benefits and costs. Accordingly the project have to be implemented more strongly under the G't financial support considering WTO and UR negociation which were aimed at achieving the free trade and improvement of international competitiveness of farm products.
