본 연구는 병리조직학적 및 전자현미경적 방법을 통해 양식산 turbot에서 발생하는 irido-like virus의 감염증을 소개하고자 한 것이다. 2003년 6월 전북 고창 소재 육상수조에서 양식중인 turbot치어에서 50∼70%의 대량폐사가 발생하였다. 병어는 사료섭취가 저하되고 힘없이 유영하다 폐사되었으며, 죽기 직전의 어류는 복부가 팽만되고 안구가 돌출되며 체색이 옅어지는 증상을 보였다. 해부학적 조사 결과, 아가미 빈혈과 간이 퇴색되어 있었으며, 특히 비장조직이 심하게 비대되어 있었다. 병어에 대한 조직학적 검사에서 비대 세포를 특징으로 하는 특이 병변이 주로 신장과 비장의 조혈조직에서 관찰되었으며, 아가미, 심장, 위, 장, 간, 췌장, 지방 조직에서도 관찰되었다. 그리고 전자현미경적 관찰 결과, 비대 세포의 세포질내에서 육각형의 지름이 136∼159 ㎚인 Irido-like virus를 관찰할 수 있었다. The high mortality of cultured juvenile turbot, Scophthalmus maximus occurred in Gochang on June, 2003. The diseased fish was lethargic with reduced feed intake. Grossly, these fish showed pale body, abdominal extension and exophthalmia. The dominant internal gross features of diseased fish were severely enlarged spleen, pale gills and or liver. Diseased fish histologically showed basophilic enlarged cells in the kidney, spleen, gill, heart, stomach, intestine, liver, pancreas and adipose tissue. Transmission electron microscopy (TEM) reveled hexagonal virions in the cytoplasm of necrotic cells. The viral particles lead a central electron-dense core and an electron translucent zone, and were 136-159 nm in diameter. These results suggest that the virus belonging to the iridoviridae was responsible for the mortality of cultured juvenile turbot.

we are taking a growing interests in special education and vocational rehabilitation for learning disabled students, but our approaches to them are not enough to meet their specific needs. In this paper, the special education and vocational rehabilitation for learning disabled students are reviewed, which implies the followings; First, the special education and vocational rehabilitation for LD students should be established legally and systematically. Second, our classifications for the handicapped should be improved to include all the handicapped, because present classification systems are much more simplfied than those of WHO's. Third, learning disabilities are lifelong probelms of individuals, therefore LD definition should be reconsidered in terms of special education and vocational rehabilitation, and educational approachs to them should be consider with their vocational rehabilitation. Fourth, being implemented through educational-industrial cooperation, special and vocational rehabilitation for LD will surmount the limitations in school environments and be able to expect more efficient results. In addition, more concrete subtypes of LD and appropriate programs for them should be studied and developed respectively. Educational systems for special teachers and rehabilitation specialists in this field should be prepared in college level.

The purposes of the present study were to estimate the prevalence of learning disabilities in the elementary school children and to identify the behavioral characteristics of learning disabled children. The standardized school achievement tests for Korean and arithmetic, intelligence test and the Myklebust's pupil Rating Scale(1981) were used as instruments. In the study, the students with general IQ above 80 but obtained Z-scores lower than-2were regarded as learning disabled children. It was found in the study that the prevalence of learning disab1ed children among 2662(boys 1397, girls 1265) in grade 3 from 18 elementary schools located in various areas in Taegu city and Kyung Sang Buk Do was 102(boys 55, girls 47), 3.83%. The Comparison of behavioral characteristics reflected on the Mykhebust's scale between learning disabled and non-disabled students were significantly different on the all of the 24 subscales of the measurement. The most significant differences were found on the orientation and spoken language subscales. Thus, learnieg disabled children were characterized by their poor abilities in finding places, conceptual judgement, time concept and expression in spoken language.

고온건식 탈황공정에서 탈황제의 황화, 재생 반응은 비촉매 기고 반응이다. 이러한 비촉매 기고 반응의 수학적 모사는 실험데이터의 설명, 공정의 설계 그리고 scale-up에 있어서 매우 중요한 정보가 된다. 탈황제의 황화, 재생 반응에는 spray dryer로 제조된 zinc titanate 탈황제를 사용하였고, 변형된 미반응핵 모델식에 적용하여 각 반응의 반응속도를 해석한 결과 탈황제의 황화반응에는 화학반응 저항과 고체 상태의 확산 저항이 회합하여 전체반응속도를 지배하며, 이때 반응속도상수는 367.67cm/min 이었고 고체상태의 확산계수는 29.66cm²/min이었다. 또한 재생반응시에 는 화학반응 저항만이 전체반응의 저항으로 관여하며, 이때의 반응속도상수는 3.45x10e cm/min이었다. In the dry-type high temprature gas desulfurization process, sulfidation and regeneration reactions of desulfrrization sorbents are noncatalytic gas-solid reactions. The mathematical modeling of noncatalytic gas-solid reactions is improtant in order to interpret laboratory data and in design and scale-up. Zinc titanate sorbent to manufacture by spray dryer is used in sulfidation and regeneration reactions of desulfuization sorbents. The result which analyzes reaction rate of sulfidation reaction by applying each reactions to modified unreacted core model is that the global reaction rate is controlled by associating with chemical reaction resistance and solid state diffusion resistance. In this case,reaction rate constant is367.67e cm/min and solid state diffusion coefficient is 29.66e cm²/min Also gloval reaction rate of regeneration reaction is controlled only by chemical reaction resistance. In this case, reaction rate constant is 3.45x10e cm/min.

The reason for the school noise problem located in the city is due to the fact that this noise is aroused by the development of industrial facilities that give too much importance to certain provinces and the cityward tendency of the population and so on. which is scattered nearby school, In addition, the indoor noise caused by the students themselves is loud. It damages the environment as would a loudspeaker, and the noise from the school itself compounded with the noise from outside raises a serious problem. Measure and analysis of the actual condition of this school noise shows its influence and effect on scholastic achievement. Noise can be felt through a man's sense, and it can be felt differently according to an individual's habit, and the time and place. That's why the physical amount, which is measured by a measuring instrument, can't display the grades of noise. The results of a survey show that students' attitudes toward noise and the students' psychological reactions are more apparent in those who take part in classes located in the south building, which is exposed to a large amount of noise from highway traffic. One important factor in the different degrees of school noise is that it becomes louder as one travels higher within the building. We can determine the different effects by comparing the scores of students from various classes. For instance, the scores of students who are exposed to this noise will be compared with those who are not. To survey how much the students themselves are effected by the noise in their studying atmospheres, we selected the north building, which the noise does not penetrate as readily as it would another building and where the measure of the noise amount(Leq, 10 min.). As a result, the classes' records will show the data between the areas where the amount of noise is high and those where the amount of noise is low. It is economically and actually difficult to make a countermeasure for the schools that are influenced by noise, but we should make plans to allocate flexible arrangements of classes and time tables, and to create a good environment for teachers to utilize their professionalism in their own subjects, a variety of teaching skills and the teaching techniques necessary to work with the various levels of the students.

The cutting tests of aluminum alloy for various hardnesses were carried out using CNC milling machine. The surface roughness(Ra, Rmax) of cut surface and cutting forces are measured at various cutting conditions such as spindle speed, feed speed and hardness. In the CNC end-milling, the surface roughness increases as feed speed increases and decreases as spindle speed increases. However, the bulit-up edge has occurred on in case of low hardness and low feed speed. In experimental conditions, as the hardness of aluminum alloy increases, the surface roughness(Ra, Rmax) decreases

The increasing stress on the need for standardized rehabilitation programs for the crippled has faced the workers in the field with the problems of finding out an ideal model of rehabilitation programs which can most facilitate maximum development of the children in various educational aspects. As part of the basic research, the study has been conducted to analyze the data on the present status of the six schools for the crippled in the country, together with other related survey on the available literature. Most of the data on the present situation of the schools and the status of the workers were obtained through questionnaires. The findings derived from the analysis of those data are as follows: 1. The Present Status of the Rehabilitation Training The survey revealed only forty-nine percent(381) of the entire subjects of 784students had been put to the training, that classroom lesson comprised 50% and 43% of the curricula in primary and secondary courses respectively, and that in the rehabilitation programs, physical therapy accounted for 50%, occupational therapy 31% and speech therapy 19%. As for the qualification of rehabilitation workers, twenty of the twenty-five who are presently serving at the six schools are license holders, averaging three physical therapists, 0ne occupational therapist and 0.2 speech therapist at each school. Ninety-six percent are junior college graduates and fifty-six percent are aged 20∼25,forty percent 26∼30. Eighty percent fall into the monthly pay range of 140,000 to 210,000 won, leaving the others below or above the scale. The study also showed that the cause or motivation of their becoming the workers was out of a sense of duty; seventy-six percent replied that they volunteered to help the crippled. Principals, the workers and special teachers showed in that order their enthusiasm about their enthusiasm about the rehabilitation prgrams. It was also found in the study that the authorities concerned have held a special guidance session once a year, achieving their annual goal only 50% and that most of the schools (82%) organized their own rehabilitation programs. The tools and other materials used in the programs were mostly(67%) domestic products. Four schools (67%) prepared thir own evaluation devices for the achievements of the trainees. 2. Facilities and Equipment for Rehabitition Training In all, thirty-four kinds of equipment and tools are currently provided at the six schools to help the chidren maintain or develop their residual function in the deficient limb. Of them only eighteen kinds were owned by each school, aberaging more than one; they were mats, walkers, parallel bars, mirrors, puzzle patches, stairs, shoulder wheels, tilt tables, walking aids, safety aids safety walking belts restorators, over head pulleys, knee exercise units, rotary wrist macihnes, holdings and gloves. The rest of the tools or apparatus averaged less than one among the schools. Nine kinds of electro therapeutic apparatus were owned by them, but only electrostimulation test machined lamps aberaged more than one. As for the hydro therapeutic apparatus, eight kinds were provided among the schools. Each school had more than one set of these three devices: hydor collator, whirl pool and hydro collator pack, with hydro collator pack averaging 17.33. They maintained thirteen kinds of occupational therapy appraratus, of which only three were owned by every school. Most of the apparatus were meant to deal with metallic works. Eleven sorts of speech therapy devices were found; only breathing exercise apparatus averaged more than one. The rehabilitation facilities and equipment at the schools are far below sufficient both in number and kind to meet the need. 3. Teacher' Attitude and Morale Toward the Rehabilitation Programs The schools for the crippled generally try to put equal emphasis on every field needed to rehabiletate the children but it was found that they were, intentionally or unintentionally, putting varying degrees of stresses on indivdual parts. The findings allowed making a list arranged in order of their priority: physical therapy, occupational therapy, speech therapy, motor development training and play therapy. The teachers responded that facilities, equipments, materials, parental cooperation, administravtive support and the ability of the rehabilitation workers were not sufficient enough to meet expectations. When asked to list the priority of the urgent fields, approximately percent put physical therapy at the top, twenty-one percent human relationships. The study showed teachers thought that the sense of duty (35%), ability and qualifications(21%), training skill(15%), academic career(13%) should be considered as the objective determinants in selecting a teacher, and 34% opined that a worker should have “ardent desire and sense of service”. Others expressed their opinion that understanding children's psychology(20%), having good knowledge of basic theory of the rehabilitation(19%) should be prerequisite to the service. Seventy-five percent of the teachers responded that rehabilitation training should be greatly improved and that they positively cooperated with the workers in the programs. It was inferred that the school administrators were generally affirmative towards the programs. The work-load of the rehabilitation workers was regarded as almost the same as that of special teachers(37%). The public and the education authorities assessed the ability of the workers "fair"(52%). Seventy-six percent of those who replied opined the financial support”, was "not sufficient", and seventy-one percent insisted the Ministry of Education should ear-mark special fund for the rehabilitation programs. As part of promotion measures, the majority of the replied(52%) reommended that authorization of more courses and expansion of the existing courses for the workers should be made, and the great majority(71%) advocated raising the special allowances, which was found to be the first in the order of priority, followed by the government's administrative and legislative support(26%) and development and development and supply of materials and equipment for the rehabilitation(22%). The analysis of the above data helped deduct a reasonable rehabilitation practice pattern in which the rehabilitation programs are adopted with the same weight as other parts of the curriculum such as classroom lessons or extra curricula activities, and the programs should cover, with an equal emphasis on every field physical therapy(functional training), occupational therapy (vocational training), speech therapy, sensory training(perception-motor training) and psychological training. Shown in IV-B are the tentatively listed basic sets of facilities and apparat believed indespensable in the rehabilitation programs. 4. Suggestions The following are the suggestion based on the results of the comprehensive study on the present rehabilitation practice in the country. (1) The rehabilitation programs which is to facilitate maximum motor-skill development should compulsorily be included in the curriculum of the school for the crippled. (2) The present training course of the rehabilitation workers should be reorganized to produce highly skilled rehabilition experts who will satisfactorily meet the need on the part of the children. Also desirable is the change of the present title of the workers "rehabilitation attendant" to "rehabilitation training teacher". In parallel with the intensification on training and requirement of the teachers, an increase in emolument to or level of the other special teachers should be made. (3) It is recommended that the programs be extended to other fields of special education, in view of the fact that the rehabilitation programs are basically meant to maintain, improve or eliminate any human defects.

This study has been conducted to achieve the following objectives: First, in order to understand the horizontal propagation and attenuation characteristics for the railroad traffic noise, we selected actively developed areas within 100 meters away from the road to measure the level of traffic noise near a road. To measure the noise near a railroad, we selected areas within 100 meters away from the railroad and then selected Saemaul-ho and Mugoongwha-ho as the subjects for our experiment, In this way, we analyzed the horizontal propagation and attenuation characteristics for the traffic noise occurring in diversified areas. Second, in order to understand the vertical propagation and attenuation characteristics for the railroad traffic noise, we measured and analyzed the distributional characteristics of vertical sound pressure levels on each floor of multi-storied apartment buildings according to changes of traffic load and types, and the existence or nonexistence of soundproof walls. For the case of the railroad traffic noise, we also selected Samaul-ho and Mugoongwha-ho as the subjects for our experiment, and we measured and analyzed the different noise levels on each floor of multi-storied apartment buildings from the soundproof wall. The results of Horizontal propagation and attenuation characteristics for the railroad traffic noise are as follows: In cases of the flat land, cutting land, and bridge area, as distance increases, the sound pressure level steadily decreases. The cutting land has an especially high distance decrease compared to the other areas, and the sound pressure level for the bridge area is higher than that of the flat land with a measurement of 9.7~17.5㏈(A). Vertical propagation and attenuation characteristics for the railroad traffic noise are as follows: The amount of sound pressure level decrease is 13.9~15.4㏈(A) for Samaul-ho and 10.9~11.5㏈(A) for Mugoongwha-ho when measuring the vertical sound pressure levels at heights lower than 4.5m, which indicates a fairly large decrease. At 6m, the amount of decrease is 7.3㏈(A) for Samaul-ho and 5.0㏈(A) for Mugoongwha-ho, which indicates a small decrease.
