본 논문에서는 복합프로그래밍 지원 환경에서 필요한 점진적 코드생성에 관한 연구를 하였다. 점진적 코드생성은 프로그램의 수정후 불 일치한 트리가 발생되었을 때 최소한의 트리를 방문하여 항상 수행 가능한 프로그램 상태를 유지할 수 있게 해준다. 또한 대상 언어에 대한 구문을 미리 인식하고 있어 구문 오류가 발생될 때 마다 즉각 수정이 가능하며, 정적 의미 분석은 context-free 또는 context-sensitive에 대한 오류를 방지할 수 있다. 본 논문에서는 점지누적 애트리뷰트 평가 알고리즘을 사용하여, 추상구문 트리에 p-code를 첨가하여 점진적 코드생성을 실험하였다. This paper is a study concerned with incremental code-generation which is in need of state which supports integrate programming environments. When after modification of the program the inconsistent tree is found, the incremental code-generator moves minimal tree and then makes the state of program capable of execution and keep it. The incremental code-generation recognized already the syntax of language. When the syntax errors occur, the program can modify immediately. Syntatic analysis can protect against context-free and context-sensitive errors. This paper uses incremental attribute evaluation algorithms and then research into incremental code-generation with abstract syntax tree adding p-code.

Cuscutae Semen extracts( Cuscuta japonica Choisy and Cuscuta australis R. Brown) were biologically evaluated in vitro and in vivo for the effects on anti-lipid peroxidation, the activities of free radical scavenging enzymes, and the content of carbonyl compound in rat liver tissues, In general, both Cuscutae Semen extracts decreased the lipid peroxides and carbonyl content in a dose-dependent manner and increased the enzyme activities dose-dependently, however, the effects of Cuscuta australis R.Brown is stronger than those of Cuscuta japonica Choisy. The obtained results are summarised as follows: 1. Cuscutae Semen extracts were decreased significantly the lipid peroxides in a dosedependent manner. The anti-lipid peroxidative effect of Cuscuta australis was stronger than that of Cuscuta japonica. Among the various extracts, methanol fraction is most effective and butanol fraction showed a weakest effect. 2. The radical scavenging effect of Cuscuta australis was stronger than that of Cuscuta japonica. The methanol fraction was most active, however, hexane and chloroform fractions exhibited practically no effect. 3. The inhibitory effect of Cuscuta australis on catalase activity was stronger than that of Cuscuta australis. 4. The inhibitory effect of Cuscuta australis on superoxide dismutase activity was somewhat stronger than that of Cuscuta japonica 5. The inhibitory effect of Cuscuta australis on the activities of GSH peroxidase, GSH S-transferase, and GSH-reductase were highter than those of Cuscuta japonica. 6. The extract of Cuscuta australis reduced the carbonyl content more stronger than that of Cuscuta japonica. In conclusion, two kinds of Cuscutae Semen exhibited significant antioxidative effects, among them, the effect of Cuscuta australis was stronger than that of Cuscuta japonica.

This study was carried out to obtain a basic information for the development of a new corn hybrid with tillers. Materials used in this study were 20 lines having three to four tillers per plant including the PI213749 U S line with non-tillers. These 20 lines were compared for the botanical characteristics and genetic distances were measured using RAPD analysis. Flowering date of the K15 was very earlier. while the K07 was very late in flowering date. Stem height and ear height were similar except for KO4 and the K15. K06, K13 and K19 lines were appeared to be resistant to lodging due to decreased ear height. Number of tillers per plant of lines used were shown three to five on average. KO9 showed the highest kernel yield, while the K08 was low. Among characteristics measured tiller per plant and flowering dates, and silking dates showed a positive correlation, while 100 kernels weight, flowering date and ear height were shown a negative with tillers per plant. A total of 17 bands by RAPD analysis using four per primer were appeared and these lines were classified into three groups, especially the third group could be classified into of four sub-groups.

A retrospective clinical and histologic study of 30 non-Hodgkin's lymphomas diagnosed at the Department of Hemato-oncology of the Chosun University from January 1989 to December 1993 is presented. Among total 30 cases whose sexes were mentioned, male were 18 and female were 12 and the ratio is 1.5:1. The peak incidence of non-Hodgkin's lymphoma was found in the third decade. The case distributions by Working formulation were summarized in table 3. The most common histopathologic type of non-Hodgkin's lymphoma was the diffuse large cell type of intermediate grade. The presenting symptoms at the time of first visit to the hospital were summarized in table 4. The most common symptoms were palpable mass. Lymph node enlargements were found in 87 %, and most frequently on cervical area(35%). The incidence of primary nodal lymphoma is more frequent than extranodal lymphoma, 1.2:1. The most common primary site of extranodal lymphoma is the gastrointestinal tract. In the laboratory findings, the data of hemoglobin and hematocrit were summarized in table 8, 9, Values of hemoglobin and hematocrit of female patients greater than those of male patients. The results of the immunophenotypings of nodal and extranodal lymphoma indicates that the B-cell lymphoma are predominant(B:T=1.4:1). The clinical stage was Ⅱ in 9 cases(30%) Ⅲ in 9 cases(30%), Ⅳ in 8 cases(26.7%), Ⅰin 4 cases(13.3%), 28 cases were treated with CHOP regimen. Among them, 17 cases(60.8%) achieved a complete remission. 5 cases had a partial response. The most frequent toxicities were toxic hepatitis.

An image retrieval system based on image content is a key issue for building and managing large multimedia detabase, such as trademarks, copyrights, art galleries, museums, picture archiving and communication system. This paper proposes a feature-based image database system where a compound feature vector representing both the color and shape of an image is used. Color information for the feature vector is obtained using the algebraic moment of each pixel of an image based on the property of regional color distribution. Shape information for the feature vector is obtained using the Improved Moment Invariant(IMI) which reduces the quantity of computation and increases retrieval efficiency. In an experiment, we have compared our methods with previous methods using a database consisting of 150 automobile images, and the results of the experiment have shown that our method has a better performance on retrieval effectiveness.

[논문] '팩션(faction)'으로서 역사 : 『다빈치 코드』 읽기

김기봉 부산대학교 인문학연구소 2006 코기토 Vol.60 No.-

The purpose of this article is to show The Da Vinci Code is a post-modern historiography based on the post-modern historical theory which denies the dichotomy of fact and fiction. Dan Brown argues that the Christianity of today is not the religion of Jesus, but that of winners. These winners include, first, men like Pietro and second, powerful persons like Constantine I. Dan Brown’s The Da Vinci Code tries to tells a rather herstory of Christianity than its history by decoding that the person suppressed by the two groups is Maria Magdalene. Such a herstory is a ‘faction’, which is a combination of fact and fiction. There is an old saying that “winners wrote a history, and losers wrote a novel.” If it is true, ‘faction’ that destroys the barrier between fact and fiction can tell the truth. Just as Hyden White argues in Metahistory, the plot putting individual facts together a story is made by historian’s imagination. Because historians invent the plot as much as discover it on the way of reading historical sources, every historiography is ultimately a ‘faction’ to combine fact and fiction.

As urbanization has been expanded in Korea, open spaces, such as urban parks and public sites, have been utilized for other uses, and then this bring out environmental changes for the worse. It is expected that these changes become more serious problems due to overpopulation, increasing individualism, and development of transportation. This research base on the consideration of connecting between decreasing urban green spaces and distributed green sites so as to build the substantial plan for the Green Network construction for urban heat island mitigation in Dalseo district, Daegu Metropolitan City. The result were as follow; 1) Connecting existing natural sites to the remained parks green zone made an Ideal form of Green-Network system. 2) Some school sites were selected for usable open spaces in order to build Green-Network system, and the plan connecting together with exist natural sites was suggested. 3) Moreover, the scheme of planting on the road spaces for connecting green spaces was proposed. 4) The devices of planting on the urban riverside for enhancing the role of urban stream to form green network was conceived.

김용기,문문만,최봉남 朝鮮大學校 附設 醫學硏究所 1993 The Medical Journal of Chosun University Vol.18 No.1

For over 100 years, the interest has been shown in evaluation of the nasal airway. As a nasal obstruction can be a subjective complaint, there is wide variation in the interpretation of the nasal symptoms. Rhinomanometry is objective, reliable, easily quantitated and a reproducible method to evaluate the nasal obstruction. 51 patients with nasal obstruction were evaluated with the active anterior rhinomanometry before and after nasal surgery and 60 patients with nomal rhinoscopic findings were evaluated with same methods as a control group. The results were as follows. 1) The mean total nasal resistance was : 1.386CmH_(2)O/LPS in control group. 2.523CmH_(2)O/LPS in patient group(p<0.05). 2) The preoperative total nasal resistance by rhinomanometry was highly correlated with subjective assessment of nasal obstruction, especially for the patient with moderate to severe symptoms of nasal obstruction. 3) In the comparison of preoperative with postoperative total nasal resistance during inspiration according to the different surgical procedure, the total nasal resistance after polypectomy was significantly decreased and the obstructive symptoms were more improved in patients who have recieved polypectomy. 4) The total nasal resistance after nasal surgery was significantly decreased from the preoperative 2.523CmH_(2)O/LPS down to the postoperative 1.512CmH_(2)O/LPS(p<0.05). 5) Therefore rhinomanometry is objectively reliable in evaluation of the nasal obstruction and the effect of nasal surgery.
