As tools to improve productivity and quality, SPC(statistical process control) and Af'Ctautomatic process control) are used in the instrumental process. In process, we know that a statistical control-in is identified with a process of random variables being independently and identically distributedriid). It IS often difficult in practice to attain a statistical control-in because of systematic time series effects like autocorrelation. When the data are autocorrelated In a process, as the diagnosis, we can use ARIMA procedure. In this thesis, a procedure is introduced to diagnose and identify a statistical control-in/out using ARIMA.

The changes of social issues and nursing concepts require the expansion of nursing needs and nursing role, therefore it is keenly demanded the necessity of the research for new curriculum development in nursing. So to make a contribution to the development of nursing education in Korea, we made a comparative study of nursing curriculum of each universities which have baccalaureate program and put them into operation at present; they are 10 Korean universities, 5 American universities and 4 Japanese Universities. Thus by researching the differences among them. We acquired the conclusions as followings. The purpose of Nursing education In case of Korean parts, the contents of those aims must be explained more clearly and more in detail than another results of research. There also has to be made the statements upon the scientific researching methodology in scholarly respect, or the self-development in individual respect, or the lasting endeavour for studies in professional respect. We must put an emphasis upon the statement and education of the direct nursing provider, or the primary health care manager at hospital and community, who is one of the important aims of modern nursing education. The substance of nursing curriculum. 1) Total credits for completion and the comparison of curriculums, classified by the field. The scope of total credits of each nation, according to Colleges ranges; Korea: 140-163, U.S.A.: 121-187, Japan: 13-158 Compared with those of U.S.A. and Japan, the average credits of Korea is higher. Classified by the field, the credits alloted to major courses are 73.3% and liberal courses, only 26%, which shows that it does not satisfy the current educational trend that emphasizes the liberal course. 2) The comparison of curriculums, classified by a school year. In case of Korea, the total credits are evenly assigned to all grades, but the freshman taken the concentration of liberal courses (81.2%). Among the major courses are preponderant the Nursing Supportive subjects in the sophomore and the nursing major ones in the junior and senior. 3) Curriculums classified by the subject. (1) As compared with those of Japan and U.S.A. Korean students are less free in chosing subjects their own way all over the curriculums. It is, therefore, required that the range of the optionals be widened for the open and flexible education. (2) We can find all of three nations (Korea, Japan, U.S.A.) neglect the sphere of the behavioral sciences among the fundamental nursing subjects. In the field of social sciences, among Korea, Japan, and U.S.A., top ranks Japan that tends of the interested in social well-being. In Korea only two universities have this subjects. (3) Nursing major subjects. Defficulties in comparing them lie in the gulfs of the title of subjects, and the structural differences of the formation of curriculums among nations. In case of Korea, although there are a few differences of the number of credit of subjects among colleges, she has uniform aspects for U.S.A., which says that there are no characteristics and self-control each colleges has in Korea. We can notice that the subjects each Korean university shares are also doubled with those of the national examination for nursing qualification. Japan differs from Korea in that subjects are more differentiated and students are provided with more chances to make a choice through the system of subjects and the texture of a curriculum are similar to those of Korea. In case of Korea, therefore, the unification of fundamental subjects (especially in the medical field) and clinical practices is required. (4) The course for teaching profession is taken as either the required or optional just in Korea (80%) and Japan (75%). The number of subjects and total credits of teaching courses is different according to the colleges of Korea and Japan. As for the contents of subjects Korea deals with theory and Japan, the practical thing with which students can adjust themselves to the spot of society. As a result of that, in case of Korea, demanded are the entire review and research upon the purpose of establishing a curriculum, its relation to the total credits and the choice of substance of subjects etc. 4) The patterns of organization in curriculum development. Most of the patterns of organization, classified by clinic subject pivot upon disease and subjests are not mutually unified in case of Korea and Japan. Though the patterns of organization of subjects if formally unified, that of curriculums is not substantially or wholy synthesized, while in case of U.S.A. the unification of the patterns of organization entire curriculum as well as the mutual unification of subjects is attained and each college runs a characteristic curriculum, since the application of nursing theory and the model of a curriculum are different according to college. The prevention of disease, the promoting health and the disease system is patterned, centering around the healthy and their families. Therefore, in case of Korea, it is urgent to unify the curriculum of nursing education for the efficiency of the future oriented nursing education, and it is also imminent to develop the new pattern of a nursing curriculum suited for our own social demand and situation. And we need the continuous studies and search for the method of application in order to development the new curriculum. The comparison of a curriculum with the purpose of nursing education. The substances of subjects are not consistently in accord with the aims of nursing education each college states in Korea, Japan and U.S.A. Especially in case of Korea, the most statements upon the purpose of education are in the social dimension, but the most subjects have the academic dimension. In Korea it is stringent to examine and study the choice of the contents of education in terms of learning, profession, individual and society.

A 10-year-old spayed female dog with history of persistent nasal discharge and halitosis was presented. In oral examination, there were severe dental calculi and gingivitis. The radiographic imaging showed lesions of left nasal cavity and periodontal membrane. In computed tomographic imaging, there are increased density of left nasal cavity, loss of nasal concha and partial defect of nasal septum. Many inflammatory cells were observed in nasal cytology. The result of culture from nasal smear was negative. All these findings result in rhinitis by dental calculi and gingivitis. The dog got improved after scaling, tooth extraction, and medical treatment.

Thin film of TiAlN was deposited onto ISO P20 tungsten carbide cutting insert tip substrate specimen using the FVAS (filtered vacuum arc system) at the substrate temperature of 80℃. Cutting and wear tests have been performed to the TiAlN coated and uncoated WC specimen, respectively under the same cutting conditions for the comparison. Cutting forces and tool wear of coated and uncoated carbide cutting tools were investigated by means of cutting length and cutting forces. Also tool wear and tool life were analyzed using the 3ch tool dynamometer amp lifier and oscilloscope. In this study cutting tests for the cutting performance of TiAlN coated WC-Co P20 to the steel alloy of SNCN420 have been curried out. Through the comparisons of cutting forces during the cutting tests and tool wear, we got the conclusions as follows.; ① In usual cutting conditions, main cutting force component showed higher value than the thrust force normal to the cutting direction especially cutting forces in the of early stage on cutting tests. But, after loosing the protective hard thin film on substrate or insert tip, the thrust force normal to the cutting direction showed much higher than main cutting force component. ② Within the range of 0.3㎜ build up edge in P20 insert tip, TiAlN coated tip was evaluated more stable in flank wear and less in crater wear than the uncoated specimen. ③ Through the wear growth curve of the specimen, tool life differences of uncoated and TiAlN coated tip at high speed (V=250[m/min]) was higher than the low speed(V=200[m/min]) case, compared to the average but the tool wear was almost same in both specimen for the case of normal wear occurred.

학교책임 경영제에서의 자율성과 책무성에 관한 연구 : focused on the School Governing Council and School Based Evaluation

Both systems of the School Governing Council and School Based Evaluation are contributing to enhance the autonomy and accountability in the School Based Management leading to improve the quality of our school education in each unit of the school. Two systems are just like a coin. Sometimes and in some cases it appears that they have different functions in different situations. But, in fact, they have substantially the same functions in our school education as well as in the school management. In the process of all the tasks of the school management to achieve the personality growth and the social growth of each person we should keep in mind the "useful value" and "credible value" in both systems of School Governing Council and school Based Evaluation. The "useful value" includes our thinking and practice for questions as follows: 1. Is it possible for all the persons to achieve self-realization through school education? 2. What are the real meanings of purpose of our school education? 3. What are the essential outcomes(rather than the superficial outcomes through our school education? 4. Only through the institution named a school, can we achieve our purposes in education? 5. Is a school really so useful institution to which we can invest all our time and effort in our school age? 6. Comparing with other educational institutions is a school such an institution as we can get so more effect that we invest to? The "credible value" includes our thinking and practice for questions as follows: 1. Is a school really a credible institution to which we can refer the education of our children? 2. Are the school programs really effective and systematic? 3. Are the teachers really equipped with so much professional knowledge and culture that they can be in charge of our school education? 4. Are their educational methods and activities really professional and educational? 5. Are the facilities and equipments really so proper and enough for our education? 6. Are the school environments really so desirable for the real education? 7. Is a school really and obviously a interesting and pleasant place for our children? In addition, we should keep in mind both positive and negative strategies to make a successful conditions for both systems. The positive strategies implies such strategies as we put so much emphasis on "making necessary situations to make two systems successful". The main strategy is centering on making the sub-structure(infra) to make two systems successful. The negative strategies implies such strategies as we put so much emphasis on "preventing the two systems from such conditions as hinder the success of two systems. The main negative strategy is centering on rooting out the possible, unexpected and unpredicted problems for two systems. After all, both systems of the School Governing Council and the School Based Evaluation goes together toward the autonomy and accountability of the school based management to lead and improve the quality of the school based education.

The tribological properties of silicon nitride in unlubricated sliding contact were investigated using a ball on disk wear apparatus at room temperature and normal load. The tribological behaviour can be classifled into two groups as follows : (1) The wear state of silicon nitride ball is divided into 3 parts, the formation of minute irragular surface resulted from plastic flow rupture, the formation of fracture surface of grain boundary and the formation of slippery surface resulted from chemical reaction. (2) The frication from of bearing steel disk is divided into 4 parts, the formation of the surface that the surface layer is shed resulted from friction wear, the formation of the surface that the microscopic friction particles are accululated resulted from corrosive wear and formation of surface that the slippery oxide tunic is created.

Using acclimated sludge with inorganic nitrogen medium for three months and non-acclimated sludge, raw sludge, under aerobic condition we investigated characteristics biological nitrogen removal. As results, e acclimated sludge under aerobic condition accomplished nitrification efficiently. But the samples from the reactor operated raw sludge had higher ammonium concentration rather than the concentration which was loaded by the medium. This means when we are trying to reorganize existing facilities, we should take high initial ammonium concentration into account.

新生兒의 生物學的 리듬에 관한 硏究

李滋衡 梨花女子大學校 韓國生活科學硏究院 1989 韓國生活科學硏究院 論叢 Vol.43 No.-

근래에 이르러 인간의 건강을 유지·증진시키고 질병을 예방 관리하는데 있어 대상자의 생물학적 리듬에 관한 이해의 중요성이 증대되고 있다. 따라서 아직 그 현상이 잘 파악되지 않은 신생아의 율동성(rhythmicity)을 활력증후, 뇨배설과 뇨중전해질을 cosinor analysis 방법을 적용 분석한 결과는 다음과 같다. 신생아의 맥박, 뇨배설, 뇨중 Cl, K는 circadian(24시간 주기)율동성이 있으며, 체온은 24시간 주기와 12시간 주기를 동시에 나타내고, 호흡과 뇨중 Na는 12시간 주기의 율동성이 있음을 확인하였다. 그러므로 신생아 상태판단에 기초지표가 되는 활력증후 및 제검사에 시간계를 고려하고, 율동성이 고려되지 않은 병원의 환경적 요소 및 치료 계획에 생물학적 리듬을 고려하여 중재되어야 할 것으로 사료된다. Recently, the increasing importance of understanding the subject's biological rhythms has been greatly emphasized on the maintenance and improvement of health care and treatment of illness. Thus this study, by way of cosinor analysis, investigated the rhythmicity of infants whose phenomena have not yet been fully defined. The results are as follows: Cosinor analysis revealed that infants demonstrated a circadian(24 hour period) rhythm for pulse, urinary flow and the chloride excretion and potassium excretion. And 12 hour period rhythmicity was found in the respiration and sodium excretion. On the other hand the temperatures were simultaneously those of 24 hour and 12 hour period. These findings are significant because they disprove the belief that the infant's physiologic activity is a constant phenomenon. And it suggests that the health care provider may be able to use a time-based plan for assessment and intervention.

大麥 및 白米 混合粉의 營養價値 硏究 : 第1報 보리의 搗精收率에 따른 營養價値 比較 硏究 Ⅰ. A Study on Some Nutritional Effects of Milling Recovery of Barley by Rats

辛炯泰,金永玉,具明子 成均館大學校 科學技術硏究所 1983 論文集 Vol.34 No.2

This experiment was conducted to observe the nutritional effects of milling recovery of barley (MRB) on the performance and digestibility by rats. Experiment was undertaken with 48 weanling male rats of Sprague-Dawley strain and they were evenly divided by 6 treatments, respectively, and feed and clean water were available, ad. libitum. In this experiment, the diets were consisted of corn starch+casein as control diet, 100%, 90%, 80%, 70% and 60% of MRB diet as experimental diets. For the experimental period, body weight gain(g), feed intake(g), feed efficiency ratio, protein efficiency ratio and digestibility (dry matter, organic matter, crude protein ; %) were measured to evaluate the nutritional effects of MRB diets for rats. The results which were obtained with this experiment as follows: 1. Average daily gain for 90%, and 100% MRB was 0.42g and for 70% MRB was 0.04g. And the differences between 80%, 90% and 100% MRB treatments and 70% and 60% MRB were significantly different(p<0.01). 2. Average daily feed intake was lower for 70% MRB of 3.41g and to increase the level of MRB tended to improve the feed intake, which followed the same pattern as the growth data. 3. Feed efficiency ratio was lower for 70% MBR of 0.01 and protein efficiency ratio was lower for 70% MRB of 0.15. 4. The range of dry matter digestibility was from 92.81% to 93.18%, organic matter digestibility was from 93.17% to 93.63% and protein digestibility was from 80.22% to 65.96% in 90%, 80%, 70% and 60% MRB, respectively. But there were no significant differences in dry matter, organic matter or protein digestibilities of experimental diets(p>0.01). And the digestibilities of dry matter, organic matter and crude protein for 100% MRB were significantly different compared with other treatments (p<0.01). So it may be concluded that 90% MRB would be the most nutritious processing method on the basis of feed intake, daily gain and protein metabolism by rats.
