Many researchers have studied the relationship between the information structure and intonation. Arguments about the relations between the information structure and intonation researched so far can be summarized as follows: the intonation of topic and focus in English information structure is represented as i) a pitch accent, ii) a tune (a pitch accent + an edge tone), or iii) a boundary tone. The purpose of this paper is to study various informational patterns of the topic in English information structure, using real TV discussion data. In this paper, the topic is classified as contrastive topics and non-contrastive topics, based on contrastiveness. The results show that the intonation of the topic in English information structure is implemented as a pitch accent, neither a tune nor a boundary tone. Of the non-contrastive topics, while anaphoric determinative NP topics (Lnc, Lncd) are mainly represented as a H* pitch accent, the pronoun topic(Lp) does not have a pitch accent. Of contrastive topics, while the semantically focused topic(Lci) is mainly represented as a H* pitch accent, the contrastively focused topic(Lcc) is represented as both H* and L+H* pitch accents. It shows that it is not always true that the topic or focus to have the meaning of contrast is represented as a L+H* pitch accent as argued in the previous researches.

In order to evaluate the artificial skin for burn would covering materials, copoly(N. carbobenzoxy-L-Iysine-L-leucine)s were prepared by Ipolymerization of N - carbobenzoxy-L- I sine anhydride and L-leucine anhydride in homogeneous solvents using triethylamine as an initiator. The synthetic polypeptides and the oxter type polyurethane(PV)of medical grade were used as the sheet type membranes were prepared ; monolayer membrances were composed of only the polypeptides, bilayer membranes and blend membranes were controlled by composition of the polypeptides and PU. Test of the swelling degree, mechanical tensile strength, elongation, oxygen permeability, water-vapor loss and In vitro degradation treated by pretense TV of samples of artificial skin were measured by adequate methods so as to mechanical, physincal characterization and biodegradation. As a result, all the values of samples were found to be similar to desired value of skin which was nature. The Artificial skin based on polypeptides can be considered as ideal burn wound covering materials.

The aim of this paper is to describe the linguistic differences of two Koreas with a special emphasis on the phonetic aspect of Seoul and Pyongyang speech. The sources of the North Korean speech material used in the study are 1) the Pyongyang radio and TV broadcasts, 2) interviews of north Korean defectors and 3) speech material of north Korean scholars collected by the writer in london, Warsaw, France and China between 1989 and 1994. The most noticeable phonetic differences of Seoul and Pyongyang speech are abstracted as follows: 1) The vowels /이/, /에/ and /애/ are higher and fronter in Pyongyang speech than in Seoul speech. 2) The vowels /우/ and /으/ of Pyongyang speech are somewhat fronter than the corresponding vowels of Seoul speech. 3) The Pyongyang vowels /으/ and if are produced with rounded lips compared to the corresponding Seoul vowels. 4) The Pyongyang vowel /h) is much lower in tongue position and at the same time somewhat fronter than the corresponding Seoul vowel. 5) The consonants /r ,i ,n / are pronounced in Pyongyang as alveolar affricates or something close to them whereas they are pronounced in Seoul as post-alveolar affricates. 6) Unlike in Seoul speech there is a very strong tendency in Pyongyang speech to reduce aspiration feature in consonant seouences such as /ㅂ+ㅎ/, /ㄷ+ㅎ/, /ㄱ+ㅎ/. 7) /ㄴ/ and /ㄹ/(flap) freely occur word-initially in Pyongyang speech whereas they are restricted in Seoul speech. 8) Unlike in Seoul speech the phonemic contrast of long and short vowels are generally not functional in Pyongyang speech. Thus the vowels pronounced long in Seoul speech are usually pronounced short in Pyongyang speech.

OLED는 유기재료를 사용하는 특수성 때문에 선명한 고품질의 화질을 얻을 수 있다. 유기재료에 따른 수명이 정해져 있지만 열에 약한 재료를 사용하기 때문에 출력되는 색의 변화를 동반할 만큼 불안정 하다. OLED는 RGB를 순서에 따라 유리 기판 상에 나열한 구조이며 각 화소의 양극과 음극은 가로와 세로로 서로 직교하고 있다. 이러한 OLED의 구조 때문에 직, 간접적으로 전이되는 열과 OLED Device에서 발생하는 자체 열로 인하여 유기소자의 특성이 변형되는, 이른바 열화현상에 쉽게 노출되어 있다. OLED Device를 제작한 후 72시간동안 8V의 전압을 인가하여 열화현상을 촉진시킨 Aging샘플을 확보 하였다. Aging된 Device의 인가전압을 3V ~ 6V까지 변화를 주고 측정해본 결과 각각의 모든 전압에서 Aging Device의 Nomalized Intensity가 상대적으로 20% 감소했음을 확인 하였다. 또한 Aging 된 Device는 As is Device에 비해 단파장 쪽으로 Shift 되는 결과를 보여주었다. 이를 분석하기 위해 CIE 색 좌표계의 NTSC (National Television System(s) Committee)를 이용하였는데, 범위 안에 있던 As is Device의 색 좌표가 Aging 후에는 NTSC범위 밖으로 이동하였는데, 이는 열화현상이 발생하기 전에 비해 방출되는 빛의 파장이 변했다는 것을 의미하며 정확한 색 재현이 안 된다는 것을 보여준다. 또한 I-V특성을 보면 Aging Device의 구동전압 (3.3V) 이 As is Device (2.7V) 에 비해 더 커지는 것을 확인하였는데 이것은 스트레스로 인해서 발생한 트랩에 의하여 캐리어의 이동도가 떨어졌기 때문에 구동 전압이 증가한 것으로 확인할 수 있다. 연구 결과를 통하여 OLED Device의 사용시간 누적에 따른 열화현상은 색 재현성과 휘도의 저하 그리고 구동전압 증가에 영향을 미친다는 것을 확인 하였다.

Evaluation is to be seen a~ a central component of design activity. It is an attempt to ensure that the proposal which arises is accepted and that the resulting artefact itself suited to its purposes in practice. Recent surveys of Evaluation show that most methods require quantitative and explicit attributes. Always a significant part of the attributes of design proposals is qualitative. Therefore we need some study that convert qualitative attributes into quantitative scale values, because in many cases con\ulcornerclusions can be drawn about the order of the overall value of the design proposals. Following to Thurstone's psychological scaling methods, attributive values are assigned by ruting scale methods, met, hod of rank-order and method of paired comparisons. The problem of psycho\ulcornerlogical scaling is then to determine whether the stimuli can be ordered on a psychological continuum with respect to the degree of the attributes each possesses. The law of comparative judgement assumes that for a given stimulus there is associated a most frequently aroused or modal discriminal process on a psychological continuum. This paper is based upon the premise that the modal discriminul process will also be the same as the mean or median of the distribution.The objective of this paper is to argue for an acceptance of qualitative approaches to the evalua\ulcornertion of Design as a complement to the existing quantitative techniques. The scale values of 10 attri\ulcornerbutes \ulcorner(1) originality, (2) aesthetics, (3) satisfaction, (4) effeciency, (5) function, (6) size, (7) texture, (8) simplicity, (9) symbol, and (10) facility) in case of TV sets are obtained and their interactions are examined.

As a direct-view flat panel displays, there are many devices, such as plasma display panels(PDPs), vacuum fluorescent displays (VFDs), and light emitting diode(LED). Among these, a PDP is the first type of panel display to be made commercially available. A 'Plasma display' is the general term for a flat display utilizing the light emission that is produced by gas discharge. However, the brightness and Luminous efficiency are still not adequate for consumer television. So, the new sustain electrode type of ac PDP was proposed. By arranging the transparent electrode of quadrangle by zigzag, the area of electrode are reduced, and the length of electrode gap is increased. It generates a high luminous efficiency(corresponding to a 40% improvement of standard type), the same discharge voltage characteristics, and the low power consumption at same luminance.

In 1972, the mural painting of Kuknakjon, which is National Treasure No. 15, at Pongjongsa was taken to pieces. From 1999. 9. 8 to 1999. 9. 15,we were precisely investigated with infrared vidicon television, video camera and so forth. The result of investigation shows that contents of the mural painting consisted of paintings of flowers and birds, paintings of Taoist hermits with supernatural powers and old historic figure paintings (In the investigated mural paintings, there were paintings about pheasant or magpie on splendid peony, figures such as Lee tae baek(이태백) and Baek lakchon(백악천) known as old chinese poets, Chang yang(장량) and Hwangsok kong(황석공) known as old historic figures and Paebok(백복), and Choksongja(적송자) known as Taoist hermits.)It is noted that the mural painting was under the influence of the later Choson culture included Taoistic and folk artistic than buddhistic contents such as painting of Bodhisattva, Arhat and apsara. Later, each mural painting will be more investigated in respect of Buddhism art historic value, and we'll make conservative treatment plan based on its result.

This result showed that the middle school students' response for the environment condition was highly negative. The major findings of this study are as follows. 1. Students would become to know the environmental pollution through reading of newspapers and TV rather than school education. 2. Students' response for air and water pollution was seriously accepted in city areas than in country areas, and in large cities than in small cities. 3. Students' response for air pollution showed that the quality of air was getting worse and major factor of air pollution was the exhausts of automobiles. 4. It showed that students' concern for water pollution was increased and water pollution was being accelerated by the increase of domestic and industrial sewages, the overuse of the agricultural chemicals, the entrophication and acid rain. 5. Students thought that soil pollution was mainly due to factory sewage, life sewage, heavy metal and agricultural medicines and so on. But now they think it is due to the degenerated and inseparable things such as used vinyle for farm and plastics. 6. Most students thought of the pollution of our country as serious. But they thought it could be removed if we tried to get rid of pollution. 7. Now students' consciousness to protect the nature took an active interest turn and was strong. Putting these various findings together, I suggested that, the efforts to turn students affirmative consciousness for the environment and a powerful plan by the nation to take off pollution should be needed. Also the education to enforce the environment preservation had to be needed.

PU block polymers are constituted by sequences of constitutional units CU which are : a diisocyanate T, a polyol or a polyamine V, an extensor E .Due to the CU different solubility parameters ,hard and soft micro domains are formed;they can aggregate into different phases. A linear PU can be described by two parameters R=T/N and $R_{E}$=(R-1)V/E.A stoichiometric model is proposed which gives the general formula of all the possible PU: X((TV)$_{k}$(TE)$_{n}$)$_{m}$X , where k and m can be calculated from the experimental molecular weights respectively of pre polymer and polymer and n= R-1.Physical properties depend on PU composition and on nature of CU. I.R. analysis is useful for discovering the hydrogen bonds location : DSC gives informations on the presence of the different phases .PALS analysis shows that nano cavities become tighter on increasing n. A series of particular Pus ,obtained from :TDI, a low molecular weight polyol, a cyclic extensor, at different R and RE was prepared and analysed. These PU are amorphous, monophasic and appear to be good candidates for membranes.nes.nes.

The purpose of this study is to provide an effective program contents of information supplied by broadcasting media with the aim of developing health program models. Health programs which have been aired and are being aired on KBS I radio, KBS, EBS, Cable TV and SBS radio were analyzed in order to understand the issues of current health programs and to design a plan for improvement. In order to address current issues of health programs, the range of health information should be extended to meet various expectations from the public audience, in addition to dealing with diagnosis and treatment of illnesses. Programs should be capable of encompassing various issues such as health practice, prevention, information on medical facilities, public health policies, daily health information, and the role of patients. As health programs function as major information sources for health services, it is necessary to raise the quality and credibility of broadcasting. Broadcasting agencies has a responsible role for public health promotion through health programs. In order to make it possible for broadcasting to fulfill its social responsibility, it is advisable to develop programs that have a clear understanding of what is the cognition of the public and the level of demand in regard to health programs.
