  • By comparing the understandings of theology major with science major in a college, this study investigates how theology major students view the origin of universe and life and how they portray the view of sciences. In addition, this study examines how theology majors change their viewpoints through a series of lectures related to understanding of the modem sciences. Twenty six theology majors and nineteen science education majors participated in the survey investigation. For theology majors, questionnaire data revealed that 42% of theology majors support theistic evolution, while 42% responses with young and old Earth creation and none with evolutionism. On the other hand, most respondents in science education major espoused evolutionism and no one with extreme creationism. Most respondents with creationism shared the insights that science is an instrument for describing the creator's work, whereas most with evolutionisms perceived science as a logical and descriptive system of the natural world. After taking science courses, the theology majors' support of an extreme view like young Earth creationism has decreased by 4% (was 23%), while their support of the theistic evolution increased by a small percentage. This result lends support to the idea that science related courses helps theology major undergraduate students to understand the scientific evolutionism based on their theological backgrounds.

  • In the 21st century, people began to pay more attention on the culture, and the chances for them to participate in the cultural lives also increased. The spaces for entertainments can also be deemed as the center of the cultural contents. The entertainment is, in consideration of its definition by the literal meaning and the origin of the word itself, 'an act that entertains, or any artificial creation that is designed to give entertainment with a view to relieve the subjects from the burdens they have as they live.'Of the modem entertainment spaces, the one with the most profound visual manifestation of the entertainment element is the club. The purpose of this study is to examine the influence from the entertaining element manifested in the club spaces. Only until a few years back, the club spaces were deemed with negative impressions that comes with the more negative side of the entertaining world. But, recently such negative impressions are lift off considerably, and the club spaces are regarded with positive impressions as to be the kind of place where the young people can enjoy performances and other kind of culture in healthy atmosphere. In Chapter 2, we will examine the entertainment and the nature of the pleasure it gives, as well as the correlation between the entertaining environments and the pleasure they give. In chapter 3, the entertaining elements within such contexts are classified into the experience, form, color, objects, and the lightings and examine the characteristics of each of them. Also, the influences of these elements to the entertaining environment will be reviewed. In the case study in chapter 4, 9 overseas and domestic club spaces that were introduced in 'Interior World' magazines, that is, in the issues that are focused on 'Entertainment,'such as Issue 59, 68, and 79. As a result of the analysis, the influences of the entertaining, or pleasing, elements were discovered. The particular expression characteristics of the pleasing designs in the club spaces are, namely, the form elements, material elements, color elements, objects elements, and the lighting elements. As the society changes and the cultural level goes up, the club spaces are required to adopt more changes. Therefore, the pleasing elements of the space should receive further emphasis. These elements will act as a trend in the space and make the people appreciate the space more refreshing.

  • This study is the first part of the investigation of the students' and teachers' understanding of ideal conditions in physics. To do this, here, we provided the theoretical basis for the above study by discussing the meaning and characteristics of idealization. Idealization, introduced and elaborated by Galileo therefore characterized the nature of modem science, can be generated by four procedures: neglecting the minor variables, giving without any description about the minor variables, assuming the limit case, assuming constancy or uniformity. Idealization generated by these procedures can produce models and laws from the sensory informations about real world. And physics world is constructed by formalization or mathematization of these models and laws obtained through idealization about real world. Therefore, it can be said that idealization have a major role in the context of discovery. By this aspects, physics world can be viewed as the approximation of the real world, and this view, again, give rise the philosophical debate about the reality in nature. Idealization take an important role in the process of application of physics world and the understanding the real world. That is, physicists accept the discrepancies between real world, and physics world and make a great effort to explain, moreover, reduce these discrepancies by modifying or eliminating idealization involved in physics world. Continued from this study, we will proceed to obtain the implications of idealization on the physics learning and investigate the students' and teachers' understanding of the ideal condition involved in the theoretical explanation and the experiment in physics.

  • This study examined the characteristics of 45 sects of seven new aboriginal religious groups in Korea including Jeungsan sect, Tangun sect, Soowoon sect, Won Buddhism, Bongnam sect, Gahksedo sect, Shamanism sect that had given a considerable influence on the modem Korean society since the end of 19th century through the field study and the review of documents. The purpose of the study was to elucidate how their religious ideas were reflected in their ceremonial costumes and what characteristics these costumes had. The results were as follows: 1. The new religious groups in Korea modified or mixed the designs or the names of existing outfits to convey their ideas or beliefs through their costumes. 2. The costumes of new religious groups had common characteristics of the times, Korean tradition and ancestor worship. 3. All the ceremonial costumes symbolized the creeds and ideas of each religion in their names, designs, and colors. The names of the costumes such as Way-Robe, Law-Robe, and Ceremony-Robe, and of the headpieces such as Sky-Crown, Lotus-Crown, Ceremony-Crown, and Sevenfold-Crown, for instance, were related with Buddhism, Taoism, and Confucianism. The most common design of costume was consisted of traditional hanbok and some type of headpiece and robe for men, and hanbok modified to Western-style for women. Most sects adopted hanbok as their ceremonial costume, but they tend to simplify its design. The color scheme of the costumes reflected the influence of the Yul-Yang and Five Elements idea but the colors varied depending on seasons and occasions to suit their creeds and philosophy. 4. These religious costumes were worn at various ceremonies, ritual, and various anniversary services for the master and other dignitaries of the sect to render greater piety to those gatherings, to distinguish the sect from other religious groups, to clarify the meaning of the ceremony, and to heighten the devout feelings of the participants. Thus, the structure (the symbol, names, and types of the outfit, and their color scheme) and religious background of the costumes of the new aboriginal religious groups in Korea turned out to have inherited and mixed various elements of traditional Korean outfits and those of existing religions to symbolize their religious ideas.

  • It is well accepted that modem emulsion explosives are intrinsically much less sensitive than traditional products such as dynamites or black powder. However, they have still been involved in a significant number of accidental explosions. In October 1975, Canadian Research, Limited's, Energetic Research Laboratory in Quebec exploded. Although explanations for the incident varied, one logical explanation was that the pump used in transporting the emulsion dead headed, thereby turning mechanical work in to frictional heating under a zero flow rate. There is a minimum pressure required for combustion(MBP) to propagate in emulsion explosives. A stable deflagration may lead to a deflagration-to-detonation transition(DDT) in emulsion explosives. Tests were also performed on sensitized sampled consisting of 6 to 21% waters as well as 1 to 11% aluminium powder. It was founded the emulsion explosives consisting of 6% waters had the lowest minimum homing pressure(MBP) of 3 bar, and the 21% waters were unable to achieve sustained homing at pressures as high as 100 bar. The aluminium contained explosives tested here displayed a MBP higher than that of without emulsion. It appears that this test may offer a firm ground for the classification of emulsion explosives in view of the regulating the hazards associated with the various process used for their manufacturing and transport.

  • Problems and current situation of public health globally and domestically were analyzed in this study and based on these findings, ways to improve from western medicine and Oriental medicine can be deduced as follows: 1. Current problems of public health in Korea and the world 1) Increase of diseases resulted from daily habits and infectious diseases, many are at the brink of being ill. Quality of life from extended life span and unbalanced health care must be solved. 2) Natural and societal factors including host factors, public health service, and other external and internal factors play an important role in deciding healthy and being ill. 3) Some of the limits and problems of modem medicine include insufficient academic knowledge and incomplete theory, as well as misled approach to the treatment. Human itself isn't perfect organism and other realistic problems hinder one's well-being. 4) Regardless of western medicine or Oriental medicine, patients were approached as someone with diseases and disorders, and wholistic approach was disregarded. Lack of clinical training, absence of clear educational philosophy and goal are some of the reasons why the education isn't under concrete system 2. Important factors for the medical education and proper direction for the education of Oriental medicine 1) Important factors for medical education - Education should not be limited on the human health and illness, but also cover qualities such as well-being, social welfare, service, and happiness. Every aspects of human life must be considered and attended for more productive outcome. - Basic understanding of humanity must be included in the educational curriculum - Foundation of human diseases and pain are associated with inner life and surrounding causes including family, society, nature, race, culture, religion, politics, and etc., thus the education must be approached to recognize aforementioned criteria. 2) Proper direction for the education of Oriental medicine - Values of Oriental medicine for medical principles and importance of lifehood must be educated. - Educational goal, limits, and levels must be established for the school of Oriental medicine - Respect for life must be the top priorities of educational direction which should lead to solution based education for the human health. Latest medical theory and technology should be accommodated as well as prevention, treatment, and balancing of basic courses and clinical training for optimal education.

  • Modem drug discovery requires rapid pharmacokinetic evaluation of chemically diverse compounds for early candidate selection. This demands the development of analytical methods that offer high-throughput of samples. Naturally, liquid chromatography / tandem mass spectrometry (LC-MS/MS) is choice of the analytical method because of its superior sensitivity and selectivity. As a result of the short analysis time(typically 3-5min) by LC-MS/MS, sample preparation has become the rate- determining step in the whole analytical cycle. Consequently tremendous efforts are being made to speed up and automate this step. In a typical automated 96-well SPE(solid-phase extraction) procedure, plasma samples are transferred to the 96-well SPE plate, internal standard and aqueous buffer solutions are added and then vacuum is applied using the robotic liquid handling system. It takes only 20-90 min to process 96 samples by automated SPE and the analyst is physically occupied for only approximately 10 min. Recently, the ultra-high flow rate liquid chromatography (turbulent-flow chromatography)has sparked a huge interest for rapid and direct quantitation of drugs in plasma. There is no sample preparation except for sample aliquotting, internal standard addition and centrifugation. This type of analysis is achieved by using a small diameter column with a large particle size(30-5O ${\mu}$m) and a high flow rate, typically between 3-5 ml/min. Silica-based monolithic HPLC columns contain a novel chromatographic support in which the traditional particulate packing has been replaced with a single, continuous network (monolith) of pcrous silica. The main advantage of such a network is decreased backpressure due to macropores (2 ${\mu}$m) throughout the network. This allows high flow rates, and hence fast analyses that are unattainable with traditional particulate columns. The reduction of particle diameter in HPLC results in increased column efficiency. use of small particles (<2 urn), however, requires p.essu.es beyond the traditional 6,000 psi of conventional pumping devices. Instrumental development in recent years has resulted in pumping devices capable of handling the requirements of columns packed with small particles. The staggered parallel HPLC system consists of four fully independent binary HPLC pumps, a modified auto sampler, and a series of switching and selector valves all controlled by a single computer program. The system improves sample throughput without sacrificing chromatographic separation or data quality. Sample throughput can be increased nearly four-fold without requiring significant changes in current analytical procedures. The process of Bioanalytical Method Validation is required by the FDA to assess and verify the performance of a chronlatographic method prior to its application in sample analysis. The validation should address the selectivity, linearity, accuracy, precision and stability of the method. This presentation will provide all overview of the work required to accomplish a full validation and show how a chromatographic method is suitable for toxirokinetic sample analysis. A liquid chromatography/tandem mass spectrometry (LC-MS/MS) method developed to quantitate drug levels in dog plasma will be used as an example of tile process.

  • This study is to investigate the recurrence characteristics of wet and dry years using over 200 year records of annual rainfall depth including Chosun Age in Korea. As well as analyzing the correlation structure of the raw data, recurrence trends of wet and dry year has been investigated based on several truncation levels (mean, $mean{\pm}0.25stdv.,\;mean{\pm}O.5stdv.,\;mean{\pm}O.75stdv.,\;mean{\pm}stdv.$). Also the transition probability among wet, dry and normal years has been derived for the same truncation levels. and finally the average return periods based on the steady-state probabilities were obtained. This analysis has been applied to not only the entire data but also partial data set of before- and after-the long dry period around 1900 in order to compare and detect the possible difference between the Chukwooki (an old raingauge invented in Chosun age) and the modem flip-bucket style. As a result, Similar pattern of dry and wet year recurrence has been found, but the return period of extremely dry years after the dry period shown longer than that before the dry period. Assuming that the dry and wet years can be defined as $mean{\pm}$ standard deviations, respectively, the return period of the wet years is shown to be about 5~6 years and that of the dry years about 6~7 years.

  • 정보통신 기술의 발달과 디지털 방송의 시작, 뉴미디어의 출현으로 인한 통신과 방송의 융합은 가속화되고 있다. 또한 2010년까지 광대역통신망 BcN과 홈네트워크 구축을 위한 정부정책이 실행 중에 있다. 100Mbps의 전송속도를 구현해야 하는 광대역 통신망(BcN)을 위해 기존 인터넷 백본 1)망은 잘 구축이 되어 있으나 가입자까지의 망 구조에 많은 문제점을 앉고 있다. 기존 전화국을 이용한 XDSL과 지역 SO를 활용한 Cable Modem의 경우 병목현상과 이론상 속도 또한 BcN과 통방통합이 요구하는 50-100Mhz의 전송속도를 만족하지 못한다. 새로운 망 구조를 구축하기 위해 많은 비용과 시간의 소요가 예상된다 가입자 망 구축에 따른 많은 방법과 이론이 제시되고 있다. 똔 논문에선 지역 SO를 활용하여 가입자까지 망을 통방통합과 BcN에 적합한 가입자 망을 새롭게 구성하는 것을 목표로 한다. 먼저 지역 50의 망을 활용하기 위해선 기존 KT와 파워콤의 COF(Glass Optical Fiber)망과 지역 케이블 SO의 HFC 망을 이용하기에는 동축케이블 망의 물리적 특성에 따른 한계로 통방통합과 BcN에 부적합하다. Tree And Branch 구조의 HFC망 대신 $SMF^{2)}$의 기존 SO의 자가망을 새롭게 설계하고 광분배망 기술인 $E-PON^{3)}$방식을 접목시켜 최대한 동축망을 사용하지 않고 굴곡 특성에 약한 $FOG^{4)}$의 특성을 극복하기 위해 $POF^{5)}$망을 이용하여 댁내 홈게이트웨이까지 연결하는 방식으로 지역 SO를 거점으로 활용하여 댁내까지 FHHT와 홈 네트워크까지의 가입자 망을 새롭게 구성하고자 한다. 저장의 효율성을 위해 이진 포멧인 IPMP화된 MP4 파일을 생성할 수 있다.으로써, 에러 이미지가 가지고 있는 엔트로피에 좀 근접하게 코딩을 할 수 있게 되었다. 이 방법은 실제로 Arithmetic Coder를 이용하는 다른 압축 방법에 그리고 적용할 수 있다. 실험 결과 압축효율은 JPEG-LS보다 약 $5\%$의 압축 성능 개선이 있었으며, CALIC과는 대등한 압축률을 보이며, 부호화/복호화 속도는 CALIC보다 우수한 것으로 나타났다.우 $23.87\%$($18.00\~30.91\%$), 갑폭 $23.99\%$($17.82\~30.48\%$), 체중 $91.51\%$($58.86\~129.14\%$)이였으며 성장율은 사육 온도구간별 차는 없었다.20 km 까지의 지점들(지점 2에서 지점 6)에서 매우 높은 값을 보이며 이는 조석작용으로 해수와 담수가 강제혼합되면서 표층퇴적물이 재부유하기 때문이라고 판단된다. 영양염류는 월별로 다소의 차이는 있으나, 대체적으로 지점 1과 2에서 가장 낮고, 상류로 갈수록 점차 증가하며 지점 7 상류역이 하류역에 비해 높은 농도이다. 월별로는 7월에 규산염, 용존무기태질소 및 암모니아의 농도가 가장 높은 반면에 용존산소포화도는 가장 낮다. 그러나 지점 14 상류역에서는 5월에 측정한 용존무기태질소, 암모니아, 인산염 및 COD 값이 7월보다 다소 높거나 비슷하다. 한편 영양염류와 COD값은 대체적으로 8월에 가장 낮으나 용존산소포화도는 가장 높다.출조건은 $100^{\circ}C$에서 1분간의 고온단시간 추출이 적합하였다. 증가를 나타내었는데
