Purpose : To measure the absorbed doses of cone beam computed tomography (CBCT), which is recently being more frequently used, and to compare them with those of panoramic radiography. Materials and Methods : To measure the absorbed doses of CBCT (PSR-9000N, Asahi Roentgen Ind. Co., Japan), we placed TLD chips on the skin regions above the parotid and thyroid glands, and on the dorsum of tongue in a dental head phantom. We used two image acquisition modes of the Dental and Panoramic modes of CBCT, which differed in the field of view. Also, panoramic radiographs (Auto IIIN, Asahi Roentgen Ind. Co., Japan) were taken to compare with the absorbed doses of CBCT. Result : In the Dental mode of CBCT, the absorbed doses of the parotid gland, dorsum of tongue, and thyroid gland were 3.53, 3.13, and 0.36 mGy, respectively. In the Panoramic mode of CBCT, they were 9.57, 9.15, and 0.85 mGy, respectively. The panoramic mode showed higher absorbed doses than those of the Dental mode. In the panoramic radiography, the absorbed doses of the parotid gland, dorsum of tongue, and thyroid gland were 1.21, 1.19, and 0.16 mGy, respectively. And they were about 1/3 of the Dental mode and 1/9 of the Panoramic mode of CBCT. Conclusion : Absorbed doses of CBCT are higher than those of panoramic radiography, and dependent upon the field of view.

황의성,정재진,김태형,김두영 동아대학교 정보기술연구소 2006 情報技術硏究所論文誌 Vol.14 No.1

MPEG-4 for an object base coding after extracting the region from image, the coding for a real-time requirements is quick and must be accurate. The object crisis algorithms of existing calculation quantity are many and with image transformation or video conferencing system to same real-time application they are not suitably. The object real-time tracking it tried to apply the CAM-Shift algorithm which is possible from the dissertation which it sees consequently. Tracking the object which it moves or wants the VO where (Video Object) tracking the user wants in bounding box form defines the object where is started. Tracking the object of after uses a CAM-Shift algorithm and are extracted and the VOP with the VO which it is composed. It defines one bounding box with the method which is proposed consequently about lower only one VOP there to be it will be able to compose, it becomes.

南勝義,尹太鴻,趙誠秀 弘益大學校 1985 弘大論叢 Vol.17 No.2

During compaction and sintering premixed Al-Cu powders, the effects of green density, sintering temperature and sintering time on dimensional change and hardness in sintered specimens were discussed and the phenomena of all conditions during age hardening were examined. The specimens were sintered in nitrogen atmosphere at temperatures ranging from 560℃ to 620℃ for 10, 20, 30 and 60 minutes. The dimensional changes of specimens during sintering are occurred in no time as the sintering temperature increased, and the expansion is occurred largely as the green density increased. The magnitude of peak hardness to age hardening is similar to wrought parts.

We added complex functional ingredients that were derived from the fermented product of Ang-Khak into a well-nutritive soybean curd in order to evaluate the function of Ang-Khak and soybean efficiently. In the production process of red soybean curd(RS) according to Ang-Khak concentration, as we compared it with a common soybean curd(CS), there were no obvious differences in the composition and yield. In the color, L- value tended to be reduced, in order of CS>RS1>RS2> RS3>RS4>RS5, as additional concentration of red rice extract increased(P<0.05). a-value tended to be the opposite way of the L-value, in order of RS5>RS4>RS3>RS2>RS1>CS(P<0.05) and b-value appeared lower than CS value overall(P<0.05). The properties of the red soybean curd's texture showed the differences in only hardness and adhesiveness(P<0.05), not in cohesiveness, springiness and gumminess. In overall sensory evaluation, the color of RS appeared red(P<0.05) and the odor(roasty) and texture(hardness) had no differences. RS was almost same value as CS in the taste, but was not as favor as much than CS in overall preference(P<0.05).

綜合的 原價 節減에 관한 考察

玄義泰 건국대학교 1971 學術誌 Vol.12 No.1

Business enterprise as an organization which may depictively be characterized by its setting up an immutable purpose of obtaining good profits is exceedingly in demand either to increase revenues or reduce the costs. Of these two, however, the appropriate cost reduction will be of food importance rather than the increase of the revenues, particularly under the very situation where the recent socio-economic structure of the country has unmistakably intensified the decree of sales competition. Here we find good grounds for the necessity of linkage between the cost reduction as a means and maximalization of profits as an objective which is not limitless. It goes without saying that the cost reduction will surely be a fundamental objective of the business, the profits increase of which the success and failure are directly connected with those of effective cost reduction. Of course, the need for cost reduction exists in vertually every business enterprise. But in the case of methodology the emphatic points should be placed on not a type of "hit-or-miss" approach, but an approach of Integrated Cost Reduction. It was the OEEC that stressed and advocated, for the first time, the necessity and availability for adaptation of the afore·said comprehensively integrated measures. In a booklet "Cost Reduction in Industry", published in 1961, gave a definition of the phrase "Integrated Cost Reduction" as follows; "...an organized continuing activity for the reduction of mists, involving all the key functions of a business and, therefore, all the key people, and containing the elements of planning, implementation and measurement". Aside from the categorization of extent of the integrated cost reduction which will have to be dull scrutinized in another paper, the focus of this paper will be placed on the main level of analysis pertaining to the aspects of both manufacturing costs and marketing costs which can be classified roughly into two main groups in accordance with a traditional standard. The process of integrated cost reduction scheme begins at a concrete cost reduction planning. To make the cost reduction plan effectively practicable a pre-planned target more than anything else must be derived from the long-range profit plan in advance. As a substantial target it must also be a reasonable cost reduction in itself and it might possibly be established by a deliberate estimation of the business environment, both in internal and external. In order to improve the business environment are there lots of complicated and difficult problems which transcend occasionally the scorer of individual enterprise's capablity. Despite of such difficulties, it imust concentrate all its eagerness and efforts to improving a mutual cooperation between the enterprise in a broader sense. In succession, a work for the reform of the business structure must set to activate. Considerations for the rationalization of the business structure may desirably be described as the following. (1) What is the most appropriate products selected to an enterprise? (2) How is the degree of appropriatenss of facilities both technically and economically? (3) Are personnel properly disposed and organized to meet their role with a higher state of efficiency at lower cost? In particular, it is very desirable for the Korean developing enterprises which belong to the open econmic system to promote an energetic drives for the realization of the business objective by means of cost reduction. In this connection, the most effective measures for this purpose of the cost reduction may be attributable to the "step by step" policy toward the specialization and specification of the manufactured goods and products for which the industry of comparative advantages should be developed and cultivated, based upon the principle of equality of international division of labor. In consequence, a low cost of, but multiple purposes of appropriate installations are estimatively to be firstly established in the afore-suggested direction. Because it is the only way to be noted to arrange the step-by-step reform of the constitutional defects, so that it would bring forth a desirable stability to the business and the foudations could be consolidated for the cost reduction. A scheme of the integrated cost reduction includes three parts of cost component analysis, special cost study and direct costing. In the meantime, the manufacturing costs consist of coot accounting by industrial engineering, material balance analysis and standard costing, and a scheme of marketing cost analysis may be adapted for the marketing costs. In conclusion, I would like to suggest a new level of methodology among the cost theories within the framework of the open system in which the integrated cost reduction might be ensured. Methodology in detail includes: (1) Micro analysis to the actual costs (2) Dynamic analysis to cost data (3) Messurement of the cost function (4) Reclassification of cost in accordance with the objectives of a business.

The purpose of this paper is to investigate the effect of divided-page teaching method on the reduction of Mathematics. Anxiety and improvement of mathematics education in elementary schools. We have chosen two groups having equal potential on mathematics. We applied the divided-page method to one group and ordinary teaching method to the other group in 4 weeks (4 hours a week). It appears that the divided-page method reduces the Mathematics Anxiety and it is very efficient teaching method to improve the effect of Mathematics education.

위선암에서 Compylobacter Pylori의 발견율

김의한,최득린,정태은 순천향대학교 1993 논문집 Vol.16 No.2

A close relationship between Campylobactor Pylori and gastric disease was reemphasized by many authors. Campylobactor was mainly observed in the antrum of the gastric mucosa, and considered as a cause of gastric ulcer following to gastritis or intestinal metaplasia. This study was carried out to observe the incidence of C.Pylori in the gastric carcinoma diagnosed by endoscopic biopsy. The following results were obtained. 1. Campylobactor pylori was identified in 61 cases(68.5%) of gastric carcinoma among 89 cases of gastric carcinoma. 2. C.Pylori was identified in 35 cases of carcinoma with intestinal metaplasia and 26 cases of that without intestinal metaplasia, indicating no difference between two groups. 3. C.Pylori was equally identified in well differentiated, moderately differentiated and poorly differentiated carcinoma. 4. C.Pylori was more frequently identified in carcinoma of antrum and pylori than that of body. The above result indicate that C.pylori may play a part of roll for the carcinogenesis of the gastric carcinoma following gastritis intestinal metaplasia and gastric ulcer

이철태,오치훈,엄의흠,송연호 조선대학교 생산기술연구소 2003 生産技術硏究 Vol.25 No.2

리튬이차전지용 정극활물질 LiCoO₂를 소성법 을 이용하여 합성공정변수를 달리하여 합성하고 합성공정변수가 이들의 물리화학적인 재료특성 및 전기화학적인 특성에 미치는 영향을 조사하였다. 출발 물질로 LiOH · H₂O와 Co₃O₄를 사용하였으며, 750℃, 6시간 이상의 조건에서 결정의 LiCoO₂가 합성되기 시작하였으며, 반응온도가 높아지고 반응시간이 길어질수록 LiCoO₂의 결정성이 증가하였다. 여러 합성 조건 중 가장 우수한 전기화학적 특성을 보이는 조건은 반응옹도 750℃ 반응시간 24시간이었다. 이 조건에서 합성한 LiCoO₂로 Li/1M LiCIO₄ in PC + DME/LiCoO₂의 cell을 구성한 후 0.25mAh/㎠며의 전류밀도로 충 · 방전 하였을 경우 초기 방전 용량은 130mAh/g이였으며, 10cycle 후 방전 용량은 130mA h/g에서 109mAh/g으로 16%의 용량감소가 일어났다. LiCoO₂, the active material of positive electrode in lithium secondary battery, was synthesized by calcination with LiOH · H₂O and C0₃O₄. And relationships between synthesis condition and physical and electrochemical characteristics of LiCoO2 were investigated. Synthesis condition of 750℃, 6hr, LiCoO₄ crystal began to be formed, and the crystallinity of LiCoO₂ increased with reaction temperature and reaction time. LiCoO₂ synthesized by calcination at 750℃ during 24hr showed best electrochemical characteristics. The initial discharge capacity of LiCoO₂ synthesized under this condition was 130mAh/g, and after 10 cycles, the discharge capacity decreased to 109mAh/g.

정의석,김선태,김선규,홍성민,정호성 大田大學校 環境問題硏究所 2002 환경문제연구소 논문집 Vol.6 No.-

From January through February 2000, the SO_2. NO_2, and VOCs (Volatile organic compounds) concentrations were measured at the total 15 sites (between 6213S and 6214S, between 5846W and 5848W) around the King Sejong Station located in King George Island. The badge type of SO_2 and NO_2 passive diffusion samplers impregnated with 5% Na_2CO_3 and TEA, respectively and VOC passive samplers including activated carbon filter were used. The samplers brought back to the laboratory were analyzed with IC or GC after extracting by distilled pure water, H_2O_2, or CS_2. Considering that the concentration level of each compound analyzed are very low in Antarctica, the blanks and instrumental detection limits were also determined. The blanks of SO_2 and NO_2 sampler were found to be 0.63 ppb and 0.49 ppb, respectively. Measured concentrations range from <LOD to 1.58 ppb for NO_2 and from <LOD to 0.44 ppb for SO_2. For ten species of VOCs investigated, on the other hand, most of compounds except for toluene and benzene could not be detected because of extremely low concentrations below the instrumental detection limits. Measured concentrations range from <LOD to 0.96ppb for toluene and from <LOD to 0.22 ppb for benzene. Although the concentrations of most gaseous contaminants investigated are observed to be very low, our results clearly show that anthropogenic emissions at King Sejong Station affect the concentrations of several of these compounds. The limited but valuable data presented in this study will be helpful to establish the systematic air monitoring system in the near future.
