하동명,이수경 社)韓國火災 ·消防學會 1996 한국화재소방학회논문지 Vol.10 No.2

An estimation methodology, based on statistics and numerical method, has been developed for estimating the upper explosive limits(UEL) of paraffinic and olefinic hydrocarbon compounds. With proposed method, the UEL has been calculated for 24 paraffinic and 10 olefinic hydrocarbon compounds. The estimated the UEL agree with the experimental values within a few percent. A comparisons with four other methods avaiable in the literature are also presented. It is hoped eventually that this method will permit estimation of the UEL with improved accuracy and broader application for other compounds.

We investigated characteristics of bacterial infection and antimicrobial suscerptibility patterns of clinical specimens in Dong Guk University Kyong Ju Hospital from october 1991 to december 1992. The types of clinical specimens requested for culture were as follows ; pus(34.2%), urine(29.6%), sputum(25.2%), blood(9.2%), etc. The most frequently isolated organisms were E. coli(17.6%), Pseudomonas(12.7%), S. aureus(12.2%), and CNS(11.2%), orderly. Predominant organisms from pus, urine and sputum were S.aureus, E. coli and Pseudomonas. Blood culture was requested 1,244 samples from 614 patients, 91 pathogeni organisms were isolated(14.8% from patient and 7.3% from requested clinical samples). E. coli was most frequently isolated(29.7%) and Salmonella typhi was noted 8.8% from the requested samples. The patterns of isolated organisms according to departments were as follows ; E.coli and Klebsiella were frequently isolated in internal medicine and general surgery, E.coli and Pseudomas in Neurosurgery, S. aureus and Pseudomonas in orthopedic surgery. In ICU, Pseudomonas was predominatly isolated and the rate of mixed infection was also high(16.4%). Most of gram-negative bacilli revealed relatively high susceptibility to Chlorampenicol, Amikacin, Tobramycin and Carbenicillin, but Acinetobacter were only susceptible to Carbenicillin and Tetrecyclin, and Serratia were to Carbenicillin and Amikacin while Salmonella were susceptible to all tested first drugs. The proportions of multi-drug resistant bacteria were 34.9% of Acinetobacter, 21.1% of Serratia, 20.0% of Pseudomonas and 15.4% of Citrobacter but Aztreonam was highly susceptible(84∼100%) except Acinetobacter. S. aureus and CNS were susceptible to Chlorampenicol, Oxacillin, Cephalothin and Vancomycin, especially, 100% susceptible to Vancomycin. But Methicillin reistant Staphylococcus aureus were very high(49%) inspite of new constructed hospital. Pneumococcus and Streptococcus species were relatively high susceptible to all tested drugs.

시나리오 스케치의 표현 공간과 시간 공간 동기화 모델

하수철,성해경 대전대학교 산업기술연구소 1998 산업기술연구소 論文集 Vol.9 No.2

게임의 일반적인 캐릭터로는 주인공, 적, 괴물, 아이템 등이 있으며, 백그라운드에는 시각적 장면과 단계별 배경이 나타난다. 이들은 시간 및 공간 개념으로 출현되도록 처리할 수 있는 처리 스키마가 필요하다. 서로 다른 개발 과정에 있거나, 이미 개발된 게임 공간에 새로운 시나리오의 스케치를 포함시키는 경우 시간(temporal)과 공간(spatial)의 개념적인 동기화가 요구된다. 본 논문에서는 게임 시나리오 스케치의 표현 공간에 대한 범주를 공간, 시간. 상대적 시공간. 절대적 시공간으로 나누며, 게임 장면 순서의 시간 관계성과 동적 장면의 공간 개념과의 동기화에 관한 표현법을 확장하는 표현모델에 대한 논의를 한다. There are heroes, enemies, monsters, items and so on in the general game characters. Visual scenes and stepwise sceneries are come out in the background. Process schema on these are needed to appear by temporal and spatial concepts. While a game is developed, or when new sketches of scenario are included in the existing game space, the conceptual temporal and spatial synchronizations are required. In this paper, we classify the categories of representation space for the sketch on the game scenario as space, time, relative temporal-space, and absolute temporal-space. Also this paper discusses on the representation model to extend the notation of temporal relation on game scene ordering and synchronization to dynamic scene with spatial concepts.

프랑스 사회당(SFIO)의 조직구조와 그 특성

하경수 진주교육대학교 2001 論文集 Vol.43 No.-

Les socialistes e´tant partisans fanatiques de l'ide´e d'organisation sans laquelle leur combat ne se conc¸oit pas, ils posse`dent une organisation e´tablie de longue date. Pour la SFIO, les statuts du parti ont e´te´ adopte´s au congre`s du Globe d'avril 1905, qui a donne´ le jour a`l'unite´ du socialisme franc¸ais. Le Parti socialiste se compose d'individus qui en acceptant les principes, le re`glement et la tactique du parti, paient une cotisation mensuelle sur laquelle s'appuient essentiellement les finances du parti. Ces volontaires s'inse`rent, en tant que membres adhe`rents, dans un cadre institutionnel, plus ou moins complexe, qui constitue le cadre ge´ne´ral de l'activit des adhe´rents. L'e´le´ment de base du parti socialiste comporte une originalite´ vis-a`-vis des radicaux et du Parti communiste. D'une part, le Parti socialiste substitue aux comite´s du parti radical, un ensemble de sections populaires. D'autre part, ignorant le syste`me de cellules d'encoupage se fait sur le plan ge´ographique et administratif : groupes, sections de la commune, fe´de´rations de´partementales et direction nationale. L'organisation de la SFIO se caracte´rise par son e´quilibre entre les aspirations du socialisme franc¸ais de´centralise´ et la tendance autoritaire du guesdisme. Le Parti socialiste doit e´tablir un e´quilibre entre de´mocratie et centralisme. Ⅱ concilie l'initiative, la liberte´ du militant, du groupe, de la fe´de´ration et leur subordination a`l'inte´re^t collectif. Ⅱ en re´sulte que l'organisation du partie`est tr s de´mocratique, de´centralise´e pour la prise des de´cisions et centralise´e pour l'action. Anisi le socialisme franc¸ais s'incarne dans un parti large aux groupes et aux fe´de´rations autonomes. Les de´cisions e´manent de la base apre`s la discussion libre dans chaque section et s'imposent aux organismes dirigeants. La liberte´ de discussion est entie`re dans les congre`s pour toutes les questions de doctrine ou de me´thode.

This research has been performed to evaluate the stoichiometric relationship between removed COD and nitrogen or phosphorus. A modified A²/O process, which was equipped with an external nitrification tank and a switching reactor, was operated with a capacity of 50㎥/d. From the results, it has been concluded that the stoichiometric values were varied by temperature condition or input COD loads. In case of denitirfication, the requirement g COD for removed nitrate nitrogen ranged 0.13 to 10.5g, and the compensation coefficient of temperature was evaluated as 1.028. For phosphorus removal, the required COD was about 7.5gCOD_(consumed)/gP_(released) and 0.54gPHACOD_(storage)/gP_(uptake). During rainy season, as it appeared a lower organic substrate loads, the PHA(Poly Hydroxy Alkanoate) contents of biomass was reduced. From the relationship between influent BOD, and the sum of removed TN and TP, the ratio for rainy and winter season was about 4.8 and 5.8g BOD/g (TN+TP) each others. Therefor, the substrat ratios for nitrogen and phosphorus removal appeared to be affected by temperature and influent organic substrate loads.

열교환기 구조 변화에 따른 NH₃와 R22의 성능특성연구

하옥남,하경수,이승재,정송태 한국공작기계학회 2005 한국공작기계학회 춘계학술대회논문집 Vol.2005 No.-

Nowadays HCFCs refrigerant are restricted because it cause depletion of ozone layer. However, natural gases such as ammonia as an organic compound, propane and propylene as hydrocarbon are easy and cheap to obtain as well as environmental. Accordingly, this experiment apply the NH3 and R22 to study the performance characteristic from the superheat control and compare the energy efficiency of two refrigerants from the high performance. The condensing pressure of refrigeration system is increased from 15bar to 16bar and degree of superheat is increased from 0 to 10℃ at each condensing pressure. As the result of experiment, when comparing the each COP, we knew the NH₃ is suitable as the alternative refrigerant of the R22.

게임 시나리오의 스케치 표현을 위한 Spatio-Temporal Logic의 시각화

하수철,성해경 대전대학교 산업기술연구소 1999 산업기술연구소 論文集 Vol.10 No.2

시간 논리(temporal logic)는 게임 공간의 동적 장면에서 현상간의 시간 순서 관계성을 표현하나 공간 축, 경로, 공간 점 및 공간 간격으로 이동할 때의 표현 방법이 결여되어 있고, 절대적/상대적 시간 및 공간에 대한 표현이 부족하다. 공간 논리(spatial logic)는 동적 장면에서 공간 및 시간 현상을 정형적으로 표현할 수 있다. 그러나, 시간과 공간을 정의하는 언명(assertion)은 시간 공간의 개념을 동시에 표현할 수 없다는 단점을 지니고 있다. 우리는 이를 극복하기 위한 표현법의 확장을 논문[1,2,3,4]에서 정의한 바 있다. 본 논문은 이를 시각적인 관점에서 표현하는 방법에 대해 논의한다. Temporal logics present the relationship of timing sequences between phenomena in dynamic scene. However, they are deficient in representation of moving case on space axis, path, space point and space interval. and not enough to express the relative/absolute time and space. Spatial logics formally present time and space phenomena in dynamic scenes, but the assertions to define time and space have defects not to present time and space concept concurrently. We had defined the representation extension to surmount it in the previous papers[1,2,3,4]. In this paper, we discuss on the methods to present them in the virtual view.
