문형택,이영무 弘益大學校 科學技術硏究所 1999 科學技術硏究論文集 Vol.10 No.1

The purpose of this thesis is to establish the design, construction and maintenance criterria for the water related problems in roofscape planning. Typical water related areas are the waterproofing, drainage and irrigation. As far as the waterproofing is concerned the present construction technique guarantees the watertight roofs on any nomal buildings. The problem occurs when the roof garden is installed on the existing waterproofing on the slab. Consequently the old waterproofing should be re-inforced to accommodate the impact of incoming plants and other hard landscape facilities such as pergolas and ponds. The caution should be taken when the soil and trees are installed because during the construction process it is easy to penetrate and ruin the watertightness of the roofing material. Also as the root system of trees grow it tends to poke holes through the waterproofing material, so in this case strong sheet must be installed to prevent the infiltration of the root system. The drainage doesn't pose serious threat as long as the proper construction is done and maintenance is regularly perfomed. If the care is neglected on the roof garden and the drain is clogged by rubbish during the heavy monsoon period as in the case of Korea the water can easily overflow the highest level of waterproofing and inundate the downstairs. This problem can be avoided by cleaning the drain covers and, to begin with, design the waterproofing devices according to the intensity of rainfall of the concerned region. As far as the irrigation is concerned it is reasonable to state that the automatic and manual irrigation should be combined together at the beginning stage. Because depending on the species and the spot where they are planted the demand for water is bound to be different it is not wise to rely soley on the automatic irrigation system. Until the plants establish their root and foliage system birmly on the growing medium it is recommended that the professional landscape personel must water the plants manualy by observing the foliage condition and judging the individual water demand. after this period the automatic system can take over. So far the water management techniques are highly developd in Germeny and Japan. As long as the climatic condition is carefully analyzed the technical application doesn't pose problems to our situation.

본 논문에서는 병렬 유전 알고리즘을 이용한 발전기 기동정지계획을 제안한다. 최소 기동 및 정지 시간 등과 같은 다양한 발전기의 제약조건을 만족시키면서 발전기 기동정지계획을 수립하는 문제는 비선형적이며 많은 국부해가 존재하므로 최적해를 탐색하는데 많은 시간이 소요된다. 이러한 문제점을 해결하기 위해 16개 의 프로세서를 가진 병렬 시스템과 이를 이용한 병렬 유전 알고리즘을 제안하였으며, 제안한 방법의 효용성을 검토하기위해 10기 및 26기의 전력계통에 적용하여 시율레이션을 시행하였다. 시율레이션 결과 기존의 방법에 비해 탐색속도를 개선하였고 우수한 해를 구할 수 있었다.

『大明律』의 性格에 대한 一考察 : 儒敎的 가치체계를 중심으로

문형진 韓國外國語大學校 外國學綜合硏究센터 中國硏究所 2004 中國硏究 Vol.33 No.-

The part of the characteristics of "the Law of Ming Dynasty" is systematically clarified the ideology of Confucianism in the legal articles and is summarized several similarities. Here are some representative examples. The idea of etiquette of Confucianism became the main part of law. There was grade of blood relationship in the family and that of status in the society. The person who violated law in order to show his/her filial piety would be dealt with leniently; while the unfilial criminal would be punished severely. All these show that the ruler on that time tried to utilize the idea of ethics of Confucianism to govern people. In order to remedy the cruelty of law for the elders, children, women, and disabled people, parading "external Confucianism and internal law", a policy of benevolent was applied the patriarch (of a family or tribe) had lots of rights, while as to the inferiors and children, their duties were stressed but their rights were ignored. There was a phenomenon of "respected official but inferior common people" in carrying out law. When "the Law of Ming Dynasty" was spread to Chao Sun, there was a huge shaking not only in religion and custom, but also in ideology etc. As to the marriage formation, it was changed from "living-in son-in-law"("率서制") to "living-in daughter-in-law"("親迎制"). The system of valuing the relatives of mother's and wife's side bacame the central system in paternal society. The system of heritage's distribution was changed from equal division to inheritance of the eldest son. The system of funeral was changed from cremation of Buddhism and fast to buring and ancestral. All these changes made the society of early Chao Sun in chaos.

In this paper, we analyze the cohesion and coupling-a functional quality evaluation model that must be considered from the design phase by the programmer-based on the National administration information's software programmed by the C language. And we measure items. That is able to evaluate the quality of affairs of National administration by the criterion of five software quality measuring methods and five testing methods. Among quality measuring items, we additionally propose the efficient parts in doing affairs of National administration such as the number of blocks in function, the number of case blocks in switch statement, the complexity of menu, the logical complexity of main menu. Making quality evaluation more detailed, we reduce the system maintenance cost and make it possible to develope qualified software.

高麗成宗의 敎育政策 : 地方 敎育强化를 通한 儒敎道德實踐 Practice of Confucian Morals by the Strengthening of the Provincial Education

文炯萬 新羅大學校 1978 論文集 Vol.6 No.-

The educational system in the Koryo dynasty was established during the reign of king Seong Jong. The establishment took almost 80 years owing to the general tendency toward "Strong subjects with weak sovereigns", with the power of the clans flourishing. However, the power of the king began to become consolidated by the 4th King Kwang Jong through adopting the Civil Service method, through conducting a public service examination, instead of appointing military people to civilian posts. Based on this examination system, the centralization of administration power was established by King seong Jong. In order to enforce the centralization effectively, he both supported the provincial education and commended filial sons and women of virtue officially. In other words, he used the Conjucian moral system as a governing policy and could control the people easily. furthermore, the inspiration of "filial piety" through the provincial education became an epochal circumstance, by means of which Confucian ethics came to be prevalent in our country.

일본 남서제도에 자생하는 두류 근연야생종집단의 분포와 집단구조를 파악하기 위해서 1999년 10월 21일부터 29일 까지 오끼나와 지역의 Hateruma, Tarama, Yonaguni 섬들에서 탐색ㆍ수집을 수향한 결과와 이들 섬으로부터 수집된 Vigna riukiuensis 집단에 대한 AFLP분석을 통하여 그들의 지리적 변이를 분석한 결과는 다음과 같다. 1. 일본의 본도에서는 발견되지 않는 Vigna riukiuensis, V. reflexo-pilosa, V. luteola, V. minima, Canavalia rosea 및 Glucine tabacina와 같은 야생종을 수집하였으며, 또한 재배종인 Macroptilium atropureum, Vigna unguiculate 및 Glycine max를 수집하였다. 2. V. riukiuensis는 잔디밭에서만 발견되었고, V. marina와 C. rosea는 해안가의 모래사장에서 주로 발견되어 두류의 내염성 육종에 유용한 재료가 될 것으로 기대되었다. 서식집단의 범위는 10여 개체에서부터 1㏊에 이르기까지 매우 다양했다. G. tabacina는 Miyako의 바닷가와 인접한 잔디밭에서만 발견되었으며, 사료작물로 도입된 M. atropureum은 대부분의 섬에서 반 재배형으로 널리 분포하고 있었다. 3. 수집된 자원은 총 74점으로서 V. riukiuensis 27점, V. reflexo-pilosa 10점, V. marina 17점, V. luteola 2점, V. unguiculate 5점, G. tabacina 5점, G. max 1점, M. atropureum 3점 및 C. rosea 4점을 각각 포함했다. 또한 이들 자원에 대한 근류균의 수집과 식물표본이 만들어 졌으며, 각 수집지점의 위치가 기록되었다. 4. V. riukiuensis집단들 사이의 지리적 유연관계는 principal coordinate analysis(PCA)에 의해 처음 두개의 주요성분은 전체변이의 57.9%를 설명했다. 전체 변이의 46.0%를 설명하는 PCA1은 Yonaguni-Ishigaki-Iromote-Hateruma집단과 Miyakowlqeks으로 구분시켰다. 전체변이의 11.9%를 설명하는 PCA2에 의해 Haterumawlqeks은 Yonaguni-Ishigaki-Iromote집단과 분리되었다. Exploration and collection of legume genetic resources was conducted on the southern islands of Okinawa prefecture, Hateruma, Iriomote, Irabu, Ishigaki, Miyako, Tarama and Yonaguni islands, Japean, from 21^(st) to 29^(th) October. 1999. From these islands, the following wild species were collected Vigna riukiuensis, V, reflexo-pilosa, V. luteola, V. marina, Canavalia rosea and Glycine tabacina and seeds or root nodules of the following cultivated species Macroptilium atropurpureum. Vigna unguicullata and Glycine max. The wild species collected were generally found in open herbaceous habitats such as roadside bushes, lawns or on beaches. Several species have specific adaptations such as V. riukiuensis and G. tabacina whic can survive in cut lawns. V. marina and C. rosea grow along sandy beaches of every island visited and may have physiological tolerances, such as salt tolerance, which may be of value in legume breeding. Population size varied greatly within and between species from less than 10 plants to covering more than 1ha. M. atropurpureum, introduced as a forage crop, has escaped and is widely changing. During this exploration and collection, V. riukiuensis and V. reflexo-pilosa , from the subgenus Ceratotropis were both found on Ishigaki, Iriomote, Yonaguni and Miyako islands. On the small island of Irabu and Tarama only V. reflexo-pilosa from the subgenus Ceratotropis was found. On Hateruma only V. riukiuensis from subgenus Ceratotropis was found. A total of 74 wild legume seed samples were collected. The comprehensive collection will enable diversity analysis to highlight islands and populations of particular genetic diversity for conservation and evaluation. Geographical variation of V. riukiuensis among the collected species was found within it's populations by AFLP analysis. Populations of Miyako island were genetically different from of other islands of Okinawa based on PCA.

조형숙,김문희 한국스포츠리서치 2003 한국 스포츠 리서치 Vol.14 No.4

This study investigates the blood MDA(malondialdehyde), SOD(superoxide dismutase), CAT(catalase) and GPX(glutathione peroxidase) activity in response to acute exhaustive swimming and selenium administration in rats. The animals in this study were chosen fourty-eight rats (Sprague -Dawley, male, 10 weeks, 300g), they were separated selenium group and placebo group. Selenium (sodium selenite, 2ppm/300g) solved in distilled water 1.0ml was administrated to them using by zoned needle at before 10 minutes swimming. The blood sampling time of two groups were three times (rest, after 30min swimming, exhaustion), 6ml blood were collected by abdominal aorta after the ethyl ether inhalation. The blood samples were centrifuged 3,000rpm for serum CAT, plasma SOD, plasma GPX and blood MDA activities analyzing. The statistical method was used by 2-way ANOVA. In summary, selenium, as a component of GPX, as a lipid soluble free radical scavenger serve and biological antioxidant defense system. selenium supplementation and acute exhaustive swimming within blood in rats enzyme activities (SOD,CAT,GPX) increase but MDA decrease. Also, our findings indicate that selenium have a positive effects to prevent the exercise induced increase in oxidative stress. Acute exhaustive swimming the improved of the body's defense capacities against free radical generation, likely as a result of adaptable increase in activities of antioxidant enzyme system.

휘발성 유기 화합물 가스(Volatile Organic Compounds)를 인식하고 분석하기 위하여 전도성 고분자 센서어레이를 이용한 시스템을 제작하였다. Polypyrrole와 Polyaniline을 화학중합법으로 센서에 전도성고분자막을 형성하였고 이를 통해 VOC 검지용 센서 어레이를 제작하였다. 센서어레이로부터 측정되는 다차원 데이터는 주성분분석법(PCA)과 RBF(Radial Basis Function Network)을 이용하였다. 제안된 시스템으로 VOCs 가스를 인식하는데 있어서 RBF Network이 PCA방식보다 더욱 효율적인 것으로 판단되었다. We fabricated gas recognition system using conducting polymer sensor array for recognizing and analyzing VOCs(Volatile Organic Compounds) gases. The polypyrrole and polyaniline thin film sensors which were made by chemical polymerization were employed to detect VOCs. The multi-dimensional sensor signals obtained from the sensor array were analyzed using PCA(principal component analysis) technique and RBF(radial basis function) Network. Throughout the experimental trails, we confirmed that RBF Network is effective than PCA technique in identifying VOCs.

In this paper we designed the content-based image system. It discovers the characteristic value of color area for the existing image, when any user establishes the special interesting region for the question images. And we designed the system to be able to search the similar image of the interesting region, compared with the table that saved the characteristic value of moment which is unchangeable for the size and the rotation of form. In this paper, we suggest the image search model based on neural network. This is able to seek for the aimed image through the feedback to search the nonlinear relations by the method of searching content-based image using SOM neural network. We make use of the Precision and the Recall that are used for the system evaluation using the similar matching method in general. As a result of the evaluation of the content-based image system, we can reduce the time and memory to find out the feature value of the image that is meaningless in the general images.
