지금까지 대부분의 메타데이터들은 응용 분야에 제한된 부분만을 주로 취급하였다. 그러나 동일한 비디오 데이터를 표현하기 위해서는 동일한 형태의 메타데이터가 필요하고, 이때 비디오 데이터베이스에서 동일한 비디오 데이터에 대하여 서로 다른 여러 개의 메타데이터를 지원해야 하는 문제가 발생한다. 이 논문에서는 이러한 문제를 해결하기 위하여 더블린 코어 모델을 확장하였다. 제안된 비디오데이터 표현에서는 더블린 코아 모델을 확장한 메타데이터가 비디오 데이터의 구조, 내용 및 조작에 관한 정보를 관리하도록 하였다. 제안된 메타 데이터는 시스템 관리 부분과 사용자 정의 부분을 분리함으로써 응용 분야에 독립적인 모델구축이 가능하다. 13개의 시간 관계 연산은 더미 샷의 시간 변환 관계를 사용하여 6개로 감소시켰다. 이 감소된 6개의 연산은 역관계를 배제시켜 표현의 일관성을 유지시키고, n-ary시간 관계의 샷들을 이진관계로 변환시킨다. 그리고 실제 응용 분야에 적용하고 실험하여 확장된 더블린 코어 모델이 응용 분야에 동일한 구조로 메타데이터를 표현하고 동일한 방법으로 검색할 수 있음을 증명하였다.

The purpose of this study was to evaluate the effect of materials and sizes of files on canal transportation in a curved canal. The stress and the strain energy of files of two kinds of materials (stainless steel and NiTi) and five sizes (No. 20, 25, 30, 35 and 40) in a curved canal were analyzed by a finite element program, NASTRAN. Curved canals in transparent resin blocks were instrumented with the 10 kinds of files, and the degree of canal transportation obtained by double exposure technique of photography was compared with the analysis by the finite element method. The results were as follows : 1. The stress of a file in a curved canal increased from the file body to the file tip. 2. The stress of a stainless steel file was about 2.5 times greater than that of a same-sized NiTi file. 3. The stress distributions of files of an identical material were the same, and the strain energies of files of an identical material increased as the size of files increased. 4. The strain energy of a No. 35 NiTi file was about the same as that of a No. 20 stainless steel file. 5. The degree of canal transportation by a stainless steel file was greater than that by a same-sized NiTi file. The degree of canal transportation generally increased as the size of a file increased. 6. The degree of canal transportation of a No. 35 NiTi file was about the same as that of a No. 20 stainless steel file.

본 논문에서는 동일한 정점의 수와 연결 정보를 갖는 N개의 삼각 메쉬의 형상을 동시에 단순화하는 새로운 기법을 제시한다. 기존의 단순화 기법을 N개의 삼각 메쉬에 각각 적용하면, 정점의 개수는 같지만 삼각형을 구성하는 연결 정보가 서로 다른 단순화 메쉬를 생성한다. 이러한 한계는 고해상도 블렌드쉐입(blend shape) 모델에서 단순화된 블렌드쉐입 모델을 구성하는 것을 어렵게 한다. 본 논문에서 제시된 기법은 N개 메쉬 형상을 동시에 고려하여 최소의 제거 비용을 갖는 에지를 선택하여 단순화를 수행한다. 따라서 단순화 결과로 생성된 N개의 단순화 메쉬는 동일한 정점의 수와 연결 정보를 유지하게 된다. 다양한 얼굴 표정을 갖는 고해상도 블렌드쉐입 모델에 동시 단순화 기법을 적용하여 단순화된 블렌드쉐입 모델을 생성함으로써 제안된 기법의 효율성과 유효성을 입증한다.

본 연구에서는 다양한 소수성 조건으로 코팅된 흙 입자 표면이 함수비 조건에 따라 분광정보에 미치는 영향을 평가하였다. 이를 위해 소수성으로 코팅된 표준사의 습윤성 실험 및 분광정보 평가 실험을 수행하였다. 습윤성 평가 결과, 1%, 3% 및 5%로 소수성 코팅된 표준사의 건조시간에 따른 표준사-물 경계면의 접촉각은 각각 약 130°~143°, 약 129°~144°와 약 131°~144°의 범위를 보였다. 이는 동일한 건조시간에서 소수성 코팅 정도가 증가할수록 접촉각은 증가하였지만, 접촉각의 범위는 동일한 범주의 습윤성을 갖는 것을 의미한다. 분광정보 평가 결과, 소수성 상태를 갖는 건조된 표준사는 친수성 상태의 표준사에 비하여 소수성 수준의 증가에 따라 최대분광반사율이 감소한 반면에, 동일한 함수비 조건에서는 소수성 정도가 증가할수록 최대분광반사율이 증가하는 것으로 평가되었다.

Objectives : Herbal medicines were used a lot in the Northeast Asia, traditionally. However, the pharmacopoeia standards in South Korea, China, Japan, Taiwan, and North Korea including many other Asia are different and cause confusion. If the origins are not belonging to same genus, it should be careful to distinguish. In this study, herbal medicines in the pharmacopoeia were analyzed for different genus of origins in order to identify the disruptive items for each country. Methods : The scientific names of herbal medicines (plant based) was analyzed origins from Pharmacopoeias of Republic of Korea, People's Republic of China, Japan, Taiwan, and Democratic People's Republic of Korea. The origins specified differently were examined. Especially, the items which have different genus were analyzed in detail and confirmed for correct scientific name. Results : The analyzed herbal medicines in Pharmacopoeia were all 753 items. 320 items were in only one country's Pharmacopoeia. 237 items were in more than two countries' Pharmacopoeia, but their origins were same on each other. The items which have different genus were 35 items. Conclusions : In general, species belonging to the same genus have similar ecological, morphological, and pharmacological activity. However, species with different genus may have different medicinal ingredients and pharmacological activity. Thus, the items which have same name but different genus are required to analyze for comparison of pharmacological activity. Also, other species belonging to the different genus should be used for different items.

After 45 patients examined as to the result of medical treatment among the ones who came to Dept. of Pain Clinic, Oriental Medical Hospital, Chunju Woosuk University complaining low back pain chiefly from Dec/19/1994 to Feb/7/1995 for 50 days or so were observed clinically, the results were obtained as follows: 1. In duration of the case history, acute stage(37.8%) was the most predominant, and subacute stage(35.6%) and chronic stage(26.7%) were revealed in turn. 2. In opinions of radiation, Spondylosis(26.7%) was the most predominant, Scoliosis(15.6%) and HIVD(11.1%) were revealed in order, and 3 cases were revealed to be negative. 3. In the radiating pain of the lower limb, the radiating pains of the left lower limb were the most predominant and those of the right lower limb and those of both lower limbs were revealed in turn. By the way, 31.1% of patients didn't suffer from the radiating pain of the lower limb. 4. In the grade of the seriousness of subsective symptom, Grade 2(66.7%) was the most predominant, and Grade 3, Grade 4, and Grade 1 followed it in order. 5. In the period of the treatments of medi-acupuncture, 2-5 day treatments(31.1%) were major and 6-10 day treatments(26.7%), 16-20 day treatments(11.1%), 26-30 day treatments(11.1%), over 31 day treatments(11.1%), 11-15 day treatments(4.4%), and 21-25 day treatments(4.4%) followed it by turns. Thus 2-10 day treatments are 57.8% and under 30 day treatments are 57.8% of all. 6. In the frequency of use of each medi-acupuncture, V was most frequency used in 41 cases(91.1%), and 11 cases of HN(24.4%), 8 cases of MOK(17.8%), 4 cases of OK(8.9%), 2 cases of B(4.4%), and a case of I(2.2%) were revealed in turn. 7. In the effect of treatments, 10 cases(22.2%) were excellent, 25 cases(55.6%) were good, 5 cases(11.1%) were fair, and 5 cases(11.1%) were poor. As the result, 88.9% of all changed for the better and all of these were improved within the third trial. 8. The effect of the treatments per durations was 100% in acute stage, 93.8% in subacute stage, and 66.7% in chronic stage. According to that, it was reavealed that the rate of treatments decreased as it came near to the chronic stage. 9. The effect of treatments per radiating pains was 87.5% in the radiating pains of the left lower limb, 81.8% in those of the right lower limb, 100% in those of both lower limbs, and 92.9% in case that patients have no radiating pains. So in the rate of treatments on radiating pains of the lower limbs, the case of both sides or no radiating pains was higher than that of one side. 10. In the effect of treatments per the condition of patients, Grade 4 showed 100% of improvement, Grade 3 showed 90.9% of improvement, Grade 2 showed 86.7% of improvement, and Grade 1 showed 100% of improvement. 11. In the effect of treatments per contents of treatments, the group treated with medi-acupuncture therapy, herb medication therapy, acupuncture therapy, and physiothrapy at the same time(Group 1) showed 100% of improvement, the group treated with medi-acupuncture therapy, acupuncture therapy, and physiotherapy simultaneously(Group 2) showed 73.7% of improvement, and the group treated with medi-acupuncture therapy and acupuncture therapy at the same time(Group 3) showed 100% of improvement. 12. 2-5 day treatments showed 78.6% of improvement, 6-10 day treatments showed 91.7% of improvement, and over 31 day treatments showed 100% of improvement. As the result, genarally the longer the period of treatment was, the better the effect of treatment was. 13. When only V was used, the rate of treatment was 96.2%. When only HN was used, the rate of treatment was 100%. When only MOK was used, the rate of treatment was 100%. When V and HN were used at the same time, the rate of treatment was 33.3%. When V and MOK were used at the same time, the rate of treatment was 100%. When V and OK were used at the same time, the rate of treatment was 100%. When V, HN, and MOK were used at the same time, the rate of treatment was 100%. When V, OK, and MOK were used at the same time, the rate of treatment was 100%. When V, MOK, and B were used at the same time, the rate of treatment was 100%. When V, HN, OK, and I were used at the same time, the rate of treatment was 100%.

It is known that the role of informal support for elderly women is critical to their physical and mental health, adjustment in old age, and their overall life satisfaction. Elderly women's situation such as social losses, widowhood, living alone, and geographic relocation etc. may result in a need for more informal supports for elderly women's health than ever before. Particularly, women's same-sex friendships were rated higher for overall quality, intimacy, enjoyment, and nurturance. Unlike a generally accepted notion that later life for women is a time of isolation and loneliness, elderly women tend to maintain and reestablish their friendship regardless their marital status and living situation. Although studies on informal support for elderly women were inconclusive in many ways, elderly women's friendship tends to be stable despite of changing health status and life events. The relative importance between daughters and friends was also controversial. This study suggests that more research with reliable measurements is necessary for the practical prevention and intervention program of elderly women's health on this issue.

Four different data reduction methods for the heat transfer coefficients from experimental data under dehumidifying conditions are compared. The four methods consist of two heat and mass transfer models and two fin efficiency models. Data are obtained from two heat exchanger samples having plain fins or wave fins. Comparison of the reduced heat transfer coefficients revealed that the single potential heat and mass transfer model yielded the humidity-independent heat transfer coefficients. Two fin efficiency models-enthalpy model and humidity model-yielded approximately the same fin efficiencies, and accordingly approximately the same heat transfer coefficients. The heat transfer coefficients under wet conditions were approximately the same as those of the dry conditions for the plain fin configuration. For the wave fin configuration, however, wet surface heat transfer coefficients were approximately 12% higher. The pressure drops of the wet surface were 10% to 45% larger than those of the dry surface.

Periodic profiling by level is a conventional method for monitoring topographic changes in a specific part of tidal zone. Periodic aerial photographs are used for monitoring topographic change of broad tidal zone area. In this study, spot heights at interval of 50m on 5 profiling lines were leveled periodically for precise monitoring topographic change of tidal zone. For monitoring broad topographic change of tidal zone, aerial photographs were also taken by film camera loaded on pilotless helicopter periodically Periodic profiling shows the change of heights on the lines well. On the other hand, aerial photographs taken by film camera loaded on pilotless helicopter have some problems to detect topographic change of tidal zone precise. Because the scale and incline of the photographs were not same, it is hard to compare them. Therefore, for more precise monitoring of topographic changes in tidal zone, it is need to take aerial pictures with same scale and same incline.
