Objectives : The purpose of this study was to examine the ethical values of dental hygiene students and set up the way of ethic educationin educational course. Methods: The subjects in this study were 948 students in four colleges located in the metropolitan area, on whom a survey was conducted. Results : 1. Regarding values of human life, they got a mean of 3.01, which showed that they sort of took a deontological view. 2. As to values of dental hygiene duties, they got a mean of 3.62, which indicated that they took a deontological view. 3. Concerning values of clients, they got a mean of 3.22, which implied that they took a deontological view. 4. As for values of collaborators, they got a mean of 3.90, which denoted that they took a very deontological view. 5. In regard to correlation among each part of their ethical values, there was a very significant correlation between their views of dental hygiene duties and human life, and between their views of clients and collaborators(p<.001). 6. As to the relationship of general characteristics to ethical values, they took a significantly different view of human life according to academic year(p<.05), religion(p<.001), religious enthusiasm(p<.0010) and attitude to the occupation of dental hygienist(p<.001). Academic year Conclusions : Regardings ethical values of dental hygiene students which showed that they took a deontological view than autilitarianism view in all parts. Accordingly, In order to establish desirable ethical values, it was scrutinized that reinforcement of education on biomedical ethics and professional ethics in curriculum was needed.

Thyroid scans using $Na^{131}I\;and\;^{99m}TcO_4^-$ in two (anterior and anterior oblique) projections were done simultaneously in 50 patients with single palpable nodule and in euthyroid state(nodular nontoxic goiter) and 20 normal subjects to evaluate the imaging ability of each radionuclide and the necessity of oblique view. In detection of a nodule as a cold or cool area, $^{99m}TcO_4^-$ was slightly superior to $^{131}I$(82 % to 78% with anterior view alone, 92% to 84% when oblique view is added in detectability), with addition of an oblique view, 5 more cold or cool area in $^{99m}Tc$ scan and 3 more $^{131}I$ scan were detected. In normal subjects $^{99m}TcO_4^-$ scan was significantly superior to $^{131}I$ scan(90% to 70%) in getting normal pattern of tracer uptake in the glands. For routine imaging study of the thyroid, $^{99m}Tc$ pertechnetate scan with multiple projection is considered to be a preferable method.

본 연구는 휘도측정장비인 CS-100과 ProMetric 1400을 활용하여 조망점의 변화에 따른 교량 경관조명의 휘도를 분석한 것이다. 이를 위하여 경관조명이 적용된 한강의 교량4개를 교량형태별로 선정하고 조망유형에 따라 한강둔치에서 바라본 조망(투시뷰), 교량주변 건물에서 바라본 조망(건물뷰), 그리고 교량 위 주행자가 바라본 조망(주행뷰) 등 3가지로 분류하였다. 연구대상의 주변하늘, 강물표면, 상부구조물, 상판측면 그리고 교각에 대한 휘도분포를 측정하였다. 분석결과, 광진교와 동호대교는 투시뷰의 휘도가 높게 나타났으며, 올림픽대교와 동작대교는 건물뷰의 휘도가 높게 나타났다. 따라서 거더교와 같이 상부구조물이 없는 교량에서는 투시뷰가, 사장교 및 아치교와 같이 상부 구조물이 있는 교량에서는 건물뷰가 경관조명의 특성을 크게 반영하는 휘도분포가 강하게 나타났다.

본 논문에서는 JVT에서 표준화가 진행 중인 다시점 비디오 부호화의 부호화 효율을 높이기 위해 다시점 비디오의 예측구조의 특성을 고려하여 움직임벡터 예측값을 선택하는 방법을 제안한다. 다시점 비디오 부호화에서 시간 방향과 뷰 방향의 예측을 수행하면서 서로 다른 성향의 움직임벡터가 발생된다. 또한 주변 블록에서 시간 방향과 뷰 방향 참조의 움직임벡터가 혼재하는 상황에서 동일한 성향의 움직임벡터가 선택되지 않는 경우가 발생되어 움직임벡터의 예측 효율이 저하된다. 이에 다시점 비디오 부호화의 예측구조에 따라 움직임벡터 예측값을 선택할 수 있는 방법을 제안한다. 제안하는 움직임벡터 예측값 선택 방법을 통하여 다시점 비디오 부호화의 압축 효율을 높일 수 있었으며, JMVM 3.6에서 움직임벡터 예측값을 선택하는 방법을 사용하는 다시점 비디오 부호화와 비교하여 PSNR(Peak Signal-to-Noise Ratio)이 약$0.03{\sim}0.1$ dB 정도 향상되었다.

유머를 유발하는 핵심요인이 불합치라는 것에서는 많은 연구자들의 견해가 일치하지만, 불합치를 유발하는 상이한 스키마들의 활성화에서는 다른 견해를 보인다. 스키마의 활성화와 관련된 견해들 중에서 대비되는 두 견해에는 동시 활성화 견해(concurrent activation view)와 선택적 활성화 견해(selective activation view)가 있다. 이 연구에서는 유머텍스트 처리에서 상이한 두 스키마들이 어떻게 활성화 되는지를 경험적으로 검증함으로써 대비되는 두 견해를 살펴보고자 하였다. 실험은 유머 텍스트를 기저-도입-불합치-해소의 4단계로 구분하여 시행하였고, 불합치는 존재하되 해소부분을 조작한 대조텍스트를 사용하였다. 실험에서는 문맥에 부합하는 스키마를 S1, 부합하지 않고 유머의 참 뜻을 나타내는 스키마를 S2라 명명하였다. 실험결과 불합치 단계에서 활성화된 스키마들이 해소 단계에서도 여전히 활성화되고, 불합치 단계에서의 S1, S2 모두 해소단계의 S1, S2와 통계적으로 유의한 차이를 보였다. 이는 불합치 단계에서는 하나의 스키마가 다른 스키마를 억제할 것이라고 가정하는 선택적 활성화 견해와는 모순되는 것이다. 이 연구의 결과는 유머 텍스트를 처리하는 과정에서 상이한 스키마들은 동시에 활성화됨을 시사한다.

The purpose of this study is to research the phychological determinant factors of window design and the relationshiops between preferences over those factors. Field surveys and questionnaires, focused on residents in apartment houses, were used to research the residents' preferences. Sunlight inflow, view privacy, and spaciousness can be assumed as major environmental psychological factors related to windows. But some difficulties in applying all those factors' requirements in a window design lie in the fundamental mutual contradiction such as providing both optimum privacy and openness. Those difficulties can be solved to a certain degree through the process of comparison between those factors based on residents' preference tendency in a specific space. Other results of this research are as follows: 1) The preference research shows that sunlight inflow stands first in living room, and followed by view, privacy, and spaciousness: privacy ranks first in bedroom and followed by sunlight inflow, view, and spaciousness: the elderly over sixties prefer the sunlight inflow first both in the living room and the bedroom. 2) Satisfaction degrees on sunlight inflow, privacy, spaciousness are increasing along with the dwelling height, while the view is not showing any relationship with the dwelling height. 3) Natural elements, as the object of view, are preferred to artificial elements such as buildings and roads. 4) Windowsill heights in bedrooms have relevance to the state of satisfaction with sunlight inflow, privacy, and view, while they show no relationship with spaciousness.

The purpose of this study was to establish the principle and the clinical application of dynamic tomogram of a human head by using the dental machine. For this study, a block of wax with details lying at three parallel planes and a human dry skull were used. This experiment was reexamined the dynamic tomogram with specialized radiographic device and view box, and the radiograms taken by the change of exposure time according to the numbers of film used in x-ray taking and taken according to the change of kVp and the types of film were analyzed density with the densitometer. From this study, the obtained results were as follows: 1. When the underexposed radiograms taken by angulation of clockwise and counter-clockwise direction of the film and skull. were superimposed and moved laterally, it was possible to focus on right and left jaws and teeth. 2. The superimposition of the two underexposed radiograms according to each condition of x-ray taking showed some differencies in density visually, and the measurement of density with the densitometer was 1.23 to 1.57 in 75kVp and 1.34 to 1.70 in 90kVp. 3. The superimposition of the two underexposed radiograms according to the kinds of x-ray film showed almost equal density visually, and the measurement of density with the densiometer was 1.34 to 1.37. 4. When seven radiograms taken by each condition of x-ray taking were superimposed on the view box, a intense rear light of view box didn't transilluminate film density regardless of the conditions of x-ray taking. Even though seven radiograms taken according to types of film were superimposed on the view box, a more intense rear light of view box was required to transilluminate total density of films. 6. Long film-object distance resulted in the enlargement and blurring of radiographic images.

The purpose of this study is to analyze correlation between the view of teaching profession and the role performance of school nurse. For the achievement of this purpose 188 school nurses in Tae-Gu city and Kyung-Sang Buk-Do are randomly selected in 1992. Major findings of this study were as follows: 1) Role performance of the school nurse showed school health room, health planning, health education, disease control, environment sanitation and management of health organization, in the order named. 2) Degree of school nurse role performance showed 84.7% of the total respondents as highly. 3) Relationship between the view of teaching profession and the role performance was statistically significant correlation. 4) Role performance of school nurse was explained 29.4% by the view of teaching profession (public life, human relation & leading student) of the total variables.

현재 MPEG(Moving Picture Expert Group)은 1998년에 시작되어 멀티미디어 콘텐츠에 관한 압축 및 표현기술에 대한 표준규격을 제정하는 기구로, 그간 MPEG-1, MPEG-2, MPEG-4, MPEG-7 규격에 대한 표준 규격을 제정해 왔다. MPEG의 표준들 중에서 3차원 비디오와 관련된 규격으로는 1996년 MPEG-2 Video 표준에 포함된 Multi-View Profile을 들 수 있다. 하지만 MPEG-2 Multi-View Profile은 주 대상이 양안시점 영상에 대한 압축규격으로, 다시점 비디오 기술을 만족시키기에는 충분하지 않다. 그리고 MPEG-2는 시점 변경에 대한 기술이 없어 다시점 비디오를 이용한 시점전환(interactive)과 같은 서비스를 제공하지 못하는 한계를 지니고 있다. 따라서 본 논문에서는 기존의 MPEG-4 시스템에 추가적으로 비디오 스위칭을 위해 특정시점을 기술할 수 있는 구조를 제안한다.
