왕숙화(王叔和)의 저작으로 알려진 ${\ulcorner}$맥경${\lrcorner}$은 중국의학사상 매우 중요한 지위를 차지하고 있다. 현재 사람들이 이 책을 중시하는 것은, 진단학의 저작일 뿐만 아니라, 그 가운데 장중경(張仲景) ${\ulcorner}$상한론(像寒論)${\lrcorner}$, ${\ulcorner}$금궤요약방${\lrcorner}$의 내용을 수록 하고 있기 때문이다. 따라서 이 책의 연구를 통해 장중경(張仲景)의 의학문헌 발전사를 살펴볼 수 있다. 본문에서는 ${\ulcorner}$맥경${\lrcorner}$과 중경(仲景)의 ${\ulcorner}$금궤${\lrcorner}$의 편장(篇章)의 목록사이의 관계를 비교하여 토론하였다. 고보혀(高保衝) 등 송신(宋臣)의 교정을 거친 ${\ulcorner}$맥경${\lrcorner}$은 비록 권수가 바뀌지 않았지만 그 내용이 여러 전적을 참고하여 이루어졌다. 중복된 글을 삭제하고 빠진 곳을 채워서 편제가 많이 바뀌어서 부류에 따라 귀속하였으므로 중대한 변화가 발생하였다. 인용문의 통계분석에 따르면, 현본 ${\ulcorner}$${\lrcorner}$ 가운데 제 1, 5, 9, 13, 19, 23편 외에, 나머지는 모두 혹은 대부분 ${\ulcorner}$맥경(？？)${\lrcorner}$에 나온다. 둘의 글자를 비교하면, 조문이 같은 것이 대부분이며, 글자가 다른 곳도 있다. 이들을 ${\ulcorner}$맥경${\lrcorner}$의 글자가 분명히 ${\ulcorner}$금궤${\lrcorner}$보다 많은 것, ${\ulcorner}$맥경${\lrcorner}$ 및 ${\ulcorner}$금궤${\lrcorner}$의 동일 조문을 서로 교정한 것 ${\ulcorner}$맥경${\lrcorner}$ 및 ${\ulcorner}$금궤${\lrcorner}$에서 피해(避害) 인해 같은 조문의 글자가 다른 것 등의 세 가지로 나누어 토론하였다. ${\ulcorner}$맥경${\lrcorner}$과 중경의서(仲景書件)의 편장목록의 비교하여 필자는 만일 왕숙화(王叔和)의 ${\ulcorner}$맥경${\lrcorner}$ 권7의 원래의 존재에 대해 완전히 부정한다면 받아들이가 어려울 것으로 본다. 본문에서 설명한 것처럼, 송신(宋臣)이 ${\ulcorner}$맥경${\lrcorner}$을 정리할 때 당시의 몇 종류의 류핸본(流핸本)을 참고하였으며, 그들은 원래의 구조에 의거하여 이 책을 10 권으로 교간(校刊)하였다. 아마도 원서의 권 7 내용이 풍부하지 않았으므로, 송신은 기타의 책을 참조하여 보충하고 수정하였으며, 추측컨대 권8, 권9도 또한 이러한 가능성이 있다. 이러한 점은 송선이 이미 서문에서 강조하여 설명한 ‘중복된 것을 제거하고, 빠진 것을 보충하였으며 그 편제도 또한 상당히 개역하여 부류에 따라 맞추도록 하였다’ 라는 것이다. 어쨌든, 중경(件景)의 ${\ulcorner}$금궤요약방${\lrcorner}$의 유전과정에서 ${\ulcorner}$맥경${\lrcorner}$은 매우 중시할 만한 문헌의 하나인 것이다.

This is a continuous study on the dam effects for the spatial extension of flood data. In this study, flood reduction rates of dams and their influences on downstream using the spatially extended flood data were implemented. Nam-Han River was selected for measuring the impacts of ChoongJu and HoangSung dams. In the evaluations of flood reduction rate at dams, the larger flood events have the lower flood reduction rates for both dams. At the YeoJoo water level station, the analyses of the relations between flood reduction rates and the sizes of watersheds dams located were performed. the sizes of watersheds having a functional dam have highly influenced on the reduction rates of flood. The average of flood reduction rates was smaller than the area rate. For instances, area rates of HoangSung (0.02) and ChoongJu dams (0.6) are larger than the average flood reduction rates for HoangSung (0.01) and ChoongJu dams (0.51), respectively. However, the water level station follows the dam flood reduction characteristics of dams themselves. The spatial effects of dam flood reductions are analyzed based on the three water level stations (GangChun, YeoJoo, YangPyung). The distance of flood reduction rates lower than 0.1 as average flood reduction rate was the area 7 times of watershed having a dam with 0.02 as a minimum reduction rate.

강수진단모형을 이용하여 저수지 이수운영을 위한 실시간 유량예측기법을 개발하였다. 강수진단모형은 현재 기상청 현업에서 수행중인 강우수치예보를 기반으로 상세 지역의 지형 효과에 의한 강수를 예측하는 정량강수예측모형(QPM; Quantitative Precipitation Model)으로서 부경대학교 환경대기과학과에서 개발된 모형이다. QPM은 중규모 예측 모형으로부터 계산된 수평 바람, 고도, 기온, 강우 강도, 그리고 상대습도 등의 예측 자료를 이용하고, 소규모 상세지형 효과를 고려함으로써 중규모 예측 모형에서 생산된 강수량 예측 값을 상세 지역의 지형을 고려한 강수량 예측 값으로 재구성하여 결과적으로 3km 간격의 상세지역 강우산출과 지형에 따른 강수량의 분포 파악이 용이할 뿐만 아니라 계산 효율성을 개선된 모형이다. QPM 검증을 위하여 기상학적 평가와 수문학적 평가를 수행하였다. 호우 사례별 일강수량의 시공간 분포로 부터, QPM을 활용한 시스템에 의한 예측결과가 원시자료 RDAPS 보다 고해상도의 예측 및 지형효과의 반영도가 높았으며, AWS의 관측자료와 비교하여 보다 높은 예측성을 보여 주었다. 대상기간인 2006년 1월 1일부터 6월 20일까지 관측강우는 총 391.5mm 였으며 RQPM은 실적강우에 비하여 119.5mm 정도 과소산정하고 있으나 분위사상과정을 거치게 되면 351.7mm로서 실적강우에 불과 10.2% 못미치고 있다. 이는 고무적인 결과로 볼 수 있으며 현업에서의 활용성이 기대되는 수준이라 볼 수 있다. 강우-유출모의를 위한 QPM신뢰도를 높이기 위하여 분위사상법(Quantile Mapping)을 이용하여 QPM모의에 존재할 수 있는 계통오차에 대한 추가적인 보정을 수행하였다. 수문학적 평가를 위하여는 장기연속유출모형인 SSARR모형을 기반으로 개발된 RRFS(Rainfall-Runoff Forecast System)을 이용하여 2006년 1월${\sim}$9월까지의 용담댐 유입량에 대하여 모의예측결과와 관측유입량 비교를 통한 검증을 수행하였다. 위 기간중 예측유입량의 RMSE(Root Mean Squared Error), COE(Sutcliffe Coefficient of Efficiency), MAE(Mean Absolute Error), $R^2$값은 각각 7.50, 0.68, 2.59, 0.69 값을 보이고 있다. 본 연구에서는 QPM에 의한 예측성의 향상 및 구축된 시스템에 의한 일강수량의 장기예측 가능성을 확인하였고, 향후 시스템을 현업에 활용하기 위해서 생산된 예측자료의 보다 장기적인 검증을 통한 시스템의 안정화가 필요할 것으로 사료된다.

A lot of mutants which cannot initiate sexual development were screened and several loci including nsdA, nsdB, nsdC, and nsdD were identified in homothallic ascomycetes Aspergillus nidulans. The NSD206, which has nsdC6 allele, showed typical phenotype of NSD (Never in sexual development) mutants. The nsdC gene was cloned by transforming NSDP697 ($nsdC^-$, $pryG^-$) with AMA1-NotI genomic library. The transforming library DNA recovered from several transformants showing wild phenotype carried about 10 kb genomic DNA insert. The DNA sequence of nsdC was analysed using GPS (Genome priming system). The nsdC gene has an open reading frame (ORF) of 1,929 bp encoding a putative polypeptide of 643 amino acids. The NsdC carries $C_2H_2C_2H_2C_2HC$ type zinc finger DNA binding domains in the middle of the polypeptide. A coiled-coil domain at its C terminus were also found. In nsdC6 allele, a single T insertion was occurred between 407-408 bp leading to the frameshift mutation and early termination of translation producing the truncated protein which has only 139 amino acids.

Growth and sexual differentiation of the seaweed Porphyra pseudolinearis Ueda have been investigated monthly in the intertidal zone of the East Sea, Korea. Young blades of P. pseudolinearis appeared at the beginning of October. Carp os pores were released at the end of November immediately after carposporangia formation. Then the thalli of P. pseudolinearis were extinguished at the end of March. Young thalli were budded through the stages of conchocelis and conchospore. Thalli showed lanceolate type in shape, cordate type in holdfast, absence of microscopic spinulate process and sexual generation. Ratios of length to width in female thalli ranged from 5.6 to 7.4 at the maturation in December and slightly decreased 3.3 to 4.8 in January and 4.9 to 7.3 in December while the ratios of male thalli ranged from 4.2 to 4.8 in January. On October 12, average five individuals were obsered in a quadrate (30 cm ${\times}$ 30 cm), 238$\pm$18 individuals for the maturation stage in December and then it was reduced to 150 individuals in February and 15 individuals in March. Average sex ratios for female, male and vegetative thalli were 31.3% 46.9% and 21.9% respectively in early December, the beginning time of sex maturation. The sex ratio of female and male thalli in December 17, changed to 69.4%, 30.6% respectively.

Design prototype is described from the stately aspect as a principle of formative art, and from the shapeable aspect of physical feature. The prototype can be a common denominator which is contained in one nation's culture, art and life, as the thing which corresponds to the daily industrial craft, architecture and art's production intention and activity with the thought and background of the culture. We have formed the design prototypes with time and space in the process which absorbs and integrates the new culture. Modern Korean design's prototype can be seen in the late Chosun. As the upper culture and sub-culture were combined, the active culture was developed. Nobody can deny that Chosun's culture and art becomes a basis of today's design and Korea's beauty. In creating the design prototype, the natural environmental factors such as topography and climate are the most important. Such natural environmental factor led the design recognition of art and craft art, as well as an architecture and indoor environment's form. Korea design produced the artisan sprite which is devoted to a moral duty and instinct as our nation's nature and emotion, and ensured the emotional process not the rational process. So, it created naturalism which accepted the material and shape. Our design prototype's path tracking as an energy of future society's new design identity, can be the important theme for our design development.

Chemical burn on the oral mucosa is caused by contact with various chemical products and manifests with localized mucositis, keratotic white lesions, bleeding, and painful tissue surface due to the coagulation of the tissue. Policresulen ($Albothyl^{(R)}$) is a topical antiseptic, commonly used over-the-counter drug for vaginitis, thrush and stomatitis. This drug is highly acidic with pH 0.6, and can act as a strong corrosive agent to oral mucosa. When inadvertently used in oral cavity, it may cause chemical burns of oral mucosa, resulting necrosis and bleeding surface resembling to erythema multifome. A 56 years old female patient presented with the chief complaints of painful ulcerations on the tongue, the upper and lower lips. On intraoral examination, an erythromatous, erosive or ulcerative surface covered with inflammatory exudates or bleeding crust is observed on the anterior half of the tongue and the upper and lower lips. She has occasionally applied the policresulen solution topically on the tongue to relieve pain from recurrent focal glossitis for about 10 years. In this time she applied it broadly and repeatedly to the tongue, the upper and lower lips for the purpose of pain relief by herself without instruction by physician or dentist. After cessation of policresulen application, the oral mucosa was rapidly recovered with use of topical steroids. In 2 weeks the lesions subsided completely. In summary, inadvertent use of $Albothyl^{(R)}$ on oral mucosa may result in chemical burn, causing mucosal erosion, ulceration and inflammation. It can be recovered by topical use of corticosteroid for 2 weeks after cessation of using $Albothyl^{(R)}$.

The study attempted to articulate standpoints towards compulsory education system based on schooling age and year in careful considerations with the gifted. For these ends, literatures were reviewed and various education laws, regulations and documents and related law reports and judicial decisions were investigated. Literature review was conducted to develop that ideas of rights to compulsory education for regular students are closely related to those for gifted. Structures of general education laws and gifted education law and regulations were compared. Later, limitations of compulsory education were discussed when it was applied for the gifted. In conclusions, it is inappropriate that the gifted are ruled by compulsory education system based on schooling age. If compulsory education system is designated to provide an effective opportunity for all students, it should be duties and rights to enter elementary schools at schooling age. However, it appeared that the duties and rights to enter elementary schools at certain schooling ages function as inhibitors against the gifted with giftedness and potentials far beyond those of regular students. Therefore, the gifted should be separately ruled under flexible systems of compulsory education if their achievement level is assessed as sufficient to enter elementary schools before schooling age. On the other hand, legal systems of compulsory education are gradually evolved to flexible systems. However, it is necessary to establish social atmosphere and support system of educational administration in order to practice the flexible system of compulsory education for the gifted.

In this paper, the parallel distributed rainfall runoff model(K-DRUM) using MPI(Message Passing Interface) technique was developed to solve the problem of calculation time as it is one of the demerits of the distributed model for performing physical and complicated numerical calculations for large scale watersheds. The K-DRUM model which is based on GIS can simulate temporal and spatial distribution of surface flow and sub-surface flow during flood period, and input parameters of ASCII format as pre-process can be extracted using ArcView. The comparison studies were performed with various domain divisions in Namgang Dam watershed in case of typoon 'Ewiniar' at 2006. The numerical simulation using the cluster system was performed to check a parallelization effectiveness increasing the domain divisions from 1 to 25. As a result, the computer memory size reduced and the calculation time was decreased with increase of divided domains. And also, the tool was suggested in order to decreasing the discharge error on each domain connections. The result shows that the calculation and communication times in each domain have to repeats three times at each time steps in order to minimization of discharge error.

In this paper, we researched the searching and tracking locations of a home resident using ON/OFF switches and sensors and designed a remote monitoring system. As an implementation environment, this system is developed on the base of the distributed object group framework we have developed from previous works. In order to trace the moving locations of a home resident, we firstly showed a home structure which attaches ON/OFF switches and sensors to home appliances and indoor facilities being fixed in home. Whenever a home resident opens/closes these objects, the signals operated from ON/OFF switches and sensors are sent to a home server system. In this time, the real locations of ON/OFF switches and sensors that the signals are being occurred must be the current location that he/she stays. A home server system provides the functionalities that map the real location of a resident in home to virtual location designed on remote desk-tops or terminals like PDAs, and that construct a healthcare database consisted of moving patterns, moving ranges, momentum for analyzing the given searching locations and times Finally, this system provides these information for remotely monitoring services.
