Tri-stimulus values of CIE-XYZ and RGB values obtained by photographic film, CCD camera or scanner depend on the spectral sensitivity of imaging devices and the spectral radiant distribution of the illumination. It is important to record and reproduce the reflectance spectra of the object for true device independent color reproduction and high accurate recording of the scene. In this paper, a method to record the reflection spectra of the object is introduced and its application to spectral endoscopes is presented.

Recently, various screen film system have been introduced in diagnostic radiology. There are two kinds of screen film system : blue emitting $CaWO_4$ screen has been largely used in these days. However, it tends to be changed to use green emitting $Gd_2O_2S$ : Tb screen. In this study, photographic characteristics of $CaWO_4$ and $Gd_2O_2S$ : Tb screen were investigated with luminescence, spectroscopy. The morphology of $CaWO_4$ and $Gd_2O_2S$ : Tb were also observed by using scanning electron microscope. The result obtained were as follows : 1. There was small difference in the thickness of phosphor layers for the front and back screen of blue emitting system, but little difference in those of green emitting system. 2. There was no difference in the size of phosphor particles between the front and back screen for each screen. However, the particle size was different for the various kinds of screens. 3. The shape of phosphor particle was round with many faces for all the screens. 4. In the exposure of X-ray with the same intensity, luminescent intensity of a green emitting system was $6{\sim}7$ times larger than that of a blue emitting system. 5. The thickness of phosphor layers does not affect on the sensitivity of the screens exposed by X-ray.

In this paper, we describe a study on the relationship between alkaline magenta emulsion manufacture and hardening test of films. The hardeners were prepared by condensation of equimolar amounts of trichlorotriazine with benzene-or naphthalene-based amino or oxy acids at 0 to $5^{\circ}C$ and at pH 7, and used as hardening agents for gelatin. The hardening test of alkaline magenta emulsion was studied at pH 8.5. For example I(R=ONa) had strong hardening properties, I substituted with an aminobenzosulfonate moiety (R=NHC6H4-p-SO3Me where Me = K, Na) was a much weaker gelatin hardener, and when substituted with amino- or oxynaphthalene derivative (II, III) did not harden gelatin at all. Compound with 2 dichlorotriazine groups as IV exhibited hardening properties. The hardener can be used in alkaline magenta emulsion layer of film and showed good hardening effect.

In this study, the behavior of water or nanofluid droplets impacting upon a hot surface was investigated by visualization of impacting phenomena with time-delayed photographic technique. Changing the mass ratio of nanofluid and the temperature of the heated surface, the characteristics of the spreading behavior and the diameter of spreading liquid film was compared between water and nanofluid droplets. The impacting droplet spreaded as a liquid film after impact and nanofluid droplets spreaded more widely than water droplets. After reaching the maximum diameter, water droplets shrinked more than nanofluid droplets. Based on this, the heat transfer area from a hot surface to impacting nanofluid droplets would be wider than that of impacting water droplets. Considering individual impacting droplet only, spray cooling using nanofluid would be better than using water.

Purpose: The purpose of this study was to compare the qualities of the four different processing chemicals (solutions). Materials and Methods: With EP 21 films(Ektaspeed plus film, Kodak Co., USA), nine unexposed and nine exposed films of a step wedge were processed utilizing automatic film processor(XR 24, Durr Co., Germany) for 5 days. During 5 days, the total number of processed films including out-patient' s intraoral films were about 400-500 for each brand. Base plus fog density, film density, contrast of processed films were measured with densitometer(model 07-443 digital densitometer, Victoreen Co., USA). These measurements were analyzed for comparison. Results: The results were as follows, 1. For the base plus fog density. there was significant difference among the four chemicals (p<0.05). The sequence of the base plus fog densities was in ascending order by Kodak, X-dol 90. Agfa and Konica. 2. For the film density. all chemicals showed useful range of photographic densities(0.25-2.5). The sequence of the film densities was in ascending order by Kodak, X-dol 90, Konica and Agfa. But there was no statistically significant difference of film density between X-dol and Kodak (p<0.05). 3. The sequence of the contrasts was in ascending order by Konica, X-dol 90, Kodak and Agfa. But there was no statistically significant difference of contrast between X-dol and Konica (p<0.05). Conclusion: These results indicated that the four processing chemicals had clinically useful film density and contrast. but only Kodak processing chemical had useful base plus fog density.

영화포스터 사진은 2시간 남짓 긴 시간동안 이어지는 영화의 내용을 축약한 한 장의 이미지다. 한 장의 이미지 속에는 영화의 내용을 알리거나 상징적으로 드러내는 사진 혹은 그림과 함께 영화제목이나 각종 카피도 표기되어, 이 모든 것을 담으려면 여러 가지 디자인 요소들이 조화롭게 구성되어야 한다. 하지만 영화포스터에서 가장 눈에 띄는 것은 사진이라 본고는 영화포스터의 기능, 역할, 유형을 알아본 뒤 포스터 사진 분석을 시도한 연구이다. 현재 영화포스터 사진제작은 전문회사가 따로 있지만 사진계에서 이미 인정받은 사진가에게 촬영을 의뢰하기도 한다. 오형근은 2000년대 초 중반 영화포스터 사진을 활발히 제작한 사진가로, 본고에서는 그의 작품 3편을 선정한 후 '영화 내용이 포스터 사진에 어떻게 재현되고 있는가'를 다루었다. 또 3편의 작품에 오형근 개인 초상사진 작업 형태와 비슷한 부분이 발견되어, 어떤 공통점이 있는지 사진미학적 관점에서 해석을 시도하였다. 3편의 작품은 <조용한 가족(1998)>, <장화, 홍련(2003)>, <스캔들-조선남녀상열지사(2003)>이다.

The purpose of this study is to know the value of the photographic subtraction technic in the transcranial oblique lateral projection of the TMJ. The author examined the transcranial oblique lateral projection radiographs which comprise 50 cases of 32 persons, compared the transcranial oblique lateral projection films and those subtraction films. The following results were obtained. 1) The condyle at closed jaw position had showed a reversed tone image, but the condyle at the opening position had showed a re-reversed ordinary image. Both condyles had showed one subtraction film because radiographic interpretation of TMJ was easy. 2) On 50 cases of subtraction films, 46 cases had showed same radiographic images compared with trascranial oblique lateral projection films. Four cases (3 cases of erosion, 1 cases of sclerosis) had showed additional changes of images so that capability of interpretation was improved.

Luxury, an expression of richness and expensiveness which can be achieved after putting in extensive an elaborate handworks, has been expressed in Hollywood movie costumes. The purpose of this thesis is to explore the characteristics of movie costumes of Hollywood studio designers, and to contemplate luxury expressed in movie costumes for such purposes, this thesis first provides the study on the luxury in movie costumes which has been reflected in fashion history, film studies and feminist theories, and to conduct a case study by analyzing photographic materials. The luxury expressed in movie costumes could be identified as expensiveness, exclusiveness, excess, and indulgence. In the movie costumes, expensive materials such as furs, jewelry, and decorations were used. Couture and custom-made costumes were the expressions of exclusivity. Also, the excessive luxury were the expression of bigness, scalelessness or extreme abundance. Indulgence in luxury is shown in use of uncommon characteristics, especially in gangster movie costumes.
