Sam-Gye-Je('Sam' means as three, 'Gye' as chinese scholar tree, and 'Je' as a house for a sacrificial rite), located in Tae-Chung-Dong, Kyungsan City, Kyungbuk, is a traditional landscape element that contains features of Je and menhir together. The object of this study is to identify a background of constriction and to analyze meanings and charateristics of the structure. To achieve these objectives, this study has conducted a literature review, an analysis of Gimun(a description of history, landscape or meaning about Je) and photograph, and a level survey. Conclusions derived from these analyses are as follows : 1. About 250 years ago, Chung-Tae-Woon who lived in Taegu, came to the Chung-Dong. He built Sam-Gye-Je where three chinese scholar trees(Sophora japonica L.) stood, followed by Jung-Lya-Goak(a monumental house of dutiful son) in 1855. It is postulated that there were three menhirs when the Sam-Gye-Je was built. 2. It is postulated that the menhir Ⅰ, Ⅲ, Ⅴ were built in Silla Dynasty or before, but it is difficult to conclude that they were built at the same time. It is because that some variations are found in the shape, the weathering state, and kind of the rock. 3. It is postulated that the Menhir Ⅱ and Ⅳ were built in 1855, it is believed that the statues were built to inherit the ancestors' high aim and life(loyalty and filial piety) to their decedants. 4. It is hard to conclude that incisions on the menhir were concurrent. However, contents of the incisions have a strong connection with the meaning of the Je, particularly in the V-menhir. Also menhir Ⅰ and Ⅴ reflected a meaning of elegance, considering the surrounding landform. 5. It is very unique to build the menhir at the Je. Furthermore, it is very interesting to arrange 5 menhirs in one line, even though they were not built at the same time. 6. The origin of the menhir and other details that is not disclosed in this study should be followed by a further research.

물류채산분석에서의 TRADE-OFF 분석

송계의 東西大學校 1998 동서논문집 Vol.4 No.-

A important concept that supports total cost system approach in logistics strategy is cost trade-off. This acknowledges that changing patterns or functions of logistics strategy will cause some costs to increase and cause other costs to decrease. For example, high interest rate result in high inventary carrying costs, prompting firms to adopt various methods--usually computer-based--to control and reduce inventories. The net effect of cost trade-off, however, should be an overall cost decrease for a given level of performance, whether for the customer or for another department of the firm. Therefore, the concept of cost trade-off is very important in logistics strategy.

보텍스 사이클론을 이용한 Toluene과 CO₂처리효율에 관한 연구

임계규 한국대기환경학회 2004 한국대기환경학회지 Vol.20 No.4

The principle of vortex tube and cyclone was introduced to enhance the treatment efficiency of waste air streams containing particulate matters, toluene, and others developed by Hangreen Tech, Ltd. and Hoseo Chemical and Industrial Technology R & D Center. Adsorption, condensation, and/or coagulation could be induced at low temperature zone formed by vortex tube and Joule-Thomson expansion. The pressurized air was introduced at the tangential direction into the cyclone system applied with the coaxial funnel tube. Easily condensible vapors such as toluene, carbon dioxide, and water vapor were adsorbed enforcedly on coagulated or condensed materials which were formed as cores for coagulation or condensation by themselves. These types of coagulation or condensation rates were rapidly promoted as the diameter being growing up. The maximum removal efficiency for carbon dioxide and toluene was achieved to about 87 and 90 percent, respectively. The Joule-Thomson coefficients were increased with the pressure of air injected in the range of the relative humidities between 10% and 30%. An optimum value was observed within the range of the tested temperatures at a fixed pressure. In conclusion, it could be identified that the treatment efficiency would be depended on the pressure of the process air introduced and physical and chemical characteristics of waste air streams containing target materials for a designed system. The final design parameters should be decided depending upon the given system and target materials.

이계주,곽손혁,서성수 충남대학교 약학대학 의약품개발연구소 1996 藥學論文集 Vol.12 No.-

An abrasive, calcium hydrogen phosphate dihydrate (DCPD), was synthesized in a Box-Wilson experimental design by reactions between phosphoric acid and milk of lime, and calcium chloride and sodium phosphate solutions, and stabilized with TSPP and TMP. The optimum conditions for preparation of DCPD from phosphoric acid with milk of lime were such as: reaction temp.: 51.9℃. conc. of lime: 25.9%. conc. of phosphoric acd: 77.9%. drying temp.: 60.2℃ and final pH: 6.46. The physico-chemical and pharmaceutical properties of DCPD were showed as follows: glycerin absorption value(68 ㎖/100g), whiteness(99.5%), particle size(10.9㎚). pH(7.8), and set test(pass). XRD and SEM of DCPD indicated a monoclinic system crystallographically. N_2 adsorption isotherm curve by BET showed non porous type Ⅱ form. The micromeritic parameters of DCPD showed that surface area was 3.27~4.6 ㎠/g and pore volume. pore area and pore radius were negligible. The rheogram of the toothpaste containing DCPD showed pseudoplastic flow with yield value of 321, and thixotropic behavior forming hysteresis loop. These results meet the requirements as abrasive standard, and sythesized DCPD is expected as a good dental abrasive such as a high quality grade in practice.

미국도서관 열람카드목록의 급속한 COM 목록 전환 경향에 관한 기술

한계문 新羅大學校 1984 論文集 Vol.16 No.-

Many libraries in the U.S. have been adopting AACR Ⅱ since January 1981. Adaopting the rule to the existing card catalogs has two options. One is to maintain a unified catalog in which AACR Ⅰ and AACR Ⅱ headings are interfiled. The other is a split catalog which devide AACR Ⅰheadings and AACR Ⅱ's at the chosen date with the adoption of AACR Ⅱ. Most libraries have selected to maintain unified card catalogs because users prefer unified catalogs even if these are card forms and libraries can manage the catalogs financially. The libraries choosing split catalogs show tendency to convert to automated catalogs with the implementation of AACR Ⅱ. Among the alternatives available for a split catalog, cad and COM combination has been the most favorable one. The reasons why the number of libraries adopting COM catalogs is increasing rapidly are as follows. 1. Changes in the catalog code. 2. Availability of machine-readable information. 3. Acceptance of microforms. 4. Cost effectiveness comparing to book or on-line catalogs. At the present, using a turnkey system for converting to a COM catalog appears to be the most cost effective alternative. Microfiche catalogues represent impressive financial savings over both book catalogs and microfilm catalogs. However, it has been proven to date that the COM catalog is not cost effective in long term outlook and the microcatalog and the supplement impede the catalog use. The libraries converting to COM catalogs or maintaining unified card catalogs have plans to start on-line catalogs when the computer prices are coming down for general use. By the wide range of technology that is becoming available, the composition of and the form of the catalogs of the future are likely to be quite different from those of the past. There will be extensive experimentation with allternative forms of the catalog to meet most effectively and efficiently the needs of the users. Many libraries will probably maintain card catalogs of some kind in the immediate future or as an interim tool during the period of transition. Although limited budgets, incompleteness of machine-readable records and other conditions may hinder libraries from making certain choices, planning and preparation for the future are essential.

유아 운동발달의 개념과 과정

This paper has focused on conceptualization and process of motor development FOR young children through the review of literature. In conceptualizing various terminologies related to both motor and development, motor development has been defined as progressive change in motor behavior throughout the life cycle brought about by interaction among the task, the individual, and the environment. Perceptual-motor development may be described as a process of attaining increased skill and functional ability by using sensory input, sensory integration, motor interpretation, movement activation, and feedback. In remedial and readiness programs, emphasis is on improving specific perceptual-motor components: body awareness, spatial awareness, directional awareness, and temporal awareness. The process of motor development begins with the early reflexive movements phase, and then progresses to the rudimentary and fundamental movement phases. Reflexes and rudimentary movement abilities appear and disappear in a fairly rigid sequence. They do, however, form an important base upon which fundamental movement abilities are developed. Fundamental movement abilities are basic movement pattern begin developing around the same time that a child is able to walk independently and move freely through his or her environment. These basic locomotor, manipulate, and stability abilities go though a definite, observable process from immaturity to maturity.

AC powder electroluminescence(EL) device consists of seven layers : PET substrate, transparent electrode, phosphor layer, dielectric layer, two layer metal electrodes and protective layer. Etch layer needs to control to improve electrical and optical properties. Both phosphor and dielectric layer among them is more important to increase its properties. For long-time reliability, proper choices of passivation and sealing material are essential. In this paper, influence of phosphor and dielectric layer thickness on EL performance is studied. Type of cellulos is selected as a sealing material to avoid moisture. To add two type of plasticizer to resin improves flexibility and passivation of EL devices. Through this experiments, technologies of fabrication low-cost thick film EL device can be established.
