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.

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.

Recently construction has become large in scale, high, complex, diverse, and professional, and its consumers demand improved quality in living environments, design and construction in building services must improve in precision. However, quite often people who carry out building services works do not prepare design documents, and poor construction with defects occur in construction site many times. To address this matter, I have conducted a questionnaire survey with students in Honam Construction Engineering Education Center and officers and students in Army Engineering School for this study. The survey is about causes of poor construction that are requirement of employing specialist of building services, setup of a service department related with the matter. After the collected guestionaire data divided according to the kinds of major business and qualification educational background work experiences, the requirements of setup of a department exclusively responsible for building services and employment of relative specialists are analyzed. Base on the above results, to suggest basic methodology of constructability improvement of building services works.

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.

모아의 조기 접촉이 어머니의 애착행위에 미치는 영향을 알아보기 위해 분만후 부터 퇴원시 까지 신생아와 육체적 접촉이 없었던 산모와 분만후 24시간내에 의도적으로 첫접촉을 시도한후 퇴원시 재접촉한 산모사이에 신생아에 대한 애착행위의 양상을 확인하였다. 1. 동일시 행동에서는 아기상태와 상태의 변화에 대해 재접촉한 산모의 반응이 높았다(P<0.01). 2. 상호작용의 양상은 시각적 접촉과 피부 접촉시 재접촉한 산모에게서 보다 진전된 반응이 나타났다(P<0.01). 3. 돌보는 행동은 재접촉한 산모들이 신생아의 요구를 확인할 수 있고, 퇴원을 위한 준비가 잘되어 있었다(P<0.01). The purpose of this study was to investigate the significance of maternal infant attachment with an emphasis upon the physical contact between a other and an infant during 24 hours of the postpartum period. Interest in this early postpartal experience was stemmed from our experience as a nurse with the newly delivered mothers and their infants. The usual postpartal care routine requires that the mother be separated from her infant. Early physical contact might have different effects between the two groups of mothers in the following three areas: 1. Identifying behaviors: Verbal statements about the infant's condition amd awareness of the changes (P<0.01). 2. Modalities of the interaction: Stimulation of the infant to open eyes (P<0.01). and fingertip touch, palm touch and touches of the baby's body(P<0.01). 3. Caretaking behaviors: Recognition of the infant's needs (P<0.05) and preparation for the infant's discharge (P<0.01).

유맹자,김형량,정희종 한국식생활문화학회 2001 韓國食生活文化學會誌 Vol.16 No.5

To develop the low-temperature and long-term fermented kimchi, kimchi was prepared according to the recipe of a specific ratio of major and minor ingredients and adjusted its salinity to 3.7%. Prepared kimchi fermented at 15±1℃ for 24 hours and transferred and fermented in a refrigerator only used to make low-temperature and long-term fermented kimchi at -1±1℃ for 30 weeks. During 30 weeks of fermentation the changes in physicochemical and microbiological properties of low-temperature and long-term fermented kimchi were studied. The initial pH of 6.47 decreased gradually and dropped to pH 4.0 after 14 weeks of fermentation, and then it maintained at same level. Acidity increased to 0.49% on 2 weeks of fermentation and kept at 0.47∼0.50% during 2 to 30 weeks fermentation. Salinity was slightly increased at early stage and started to decrease on 4 weeks of fermentation, and then it did not change. The change of reducing sugar content was closely related to the trend of pH change with a very high correlation coefficient(r=0.912). Lactic acid, citric acid, malic acid, succinic acid and acetic acid were major organic acids contained in low-temperature and long-term fermented kimchi. Vitamin C content decreased at initial stage of fermentation and then slightly increased up to the maximum of 22.3㎎% on 8 weeks of fermentation. In color measurement, L value continued to increase during the fermentation and reached at the highest of 55.45 on 22 weeks of fermentation, and a and b values of 3.62 and 4.54 also increased to 31.26 and 37.32 on 30 weeks of fermentation, respectively. Total microbial count increased slowly from beginning and was the highest on 4 weeks of fermentation, and then began to decrease slowly. Count of lactobacillus spp. was highest after 6 weeks, but count of Leuconostoc spp. was highest on 2 weeks of fermentation, and then both showed a slow decrease. Yeast count wasn't increased until 4 weeks of fermentation and then increased rapidly to get the highest on 10 weeks of fermentation.

新生兒의 生物學的 리듬에 관한 硏究

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.

金亨資,全泰玉,加藤康司 釜山工業大學校 1994 論文集 Vol.36 No.-

Sliding friction between spherical pin of 8mm in diameter and flat(disk) substrates coated with vacuum-deposited thin film was measured under on ultra high vacuum pressure for various materials, rate of film supply(8∼210nm/min), sliding velocity(1.5∼67.0nm/s), flash temperature. It was found that the most effective lubrication is obtained when the adhesion between pin of Si₃N₄ and disk of SUS440C is high and that between pin of Si₃N₄ and disk of Si₃N₄ is low. When In film is used as a lubricant between pin of Si₃N₄ and disk of stainless steel, the friction coefficient has a value as low as 0.04. In this case, the normal load W and the sliding velocity V are expressed as 1ON and 24mm/s for 10??Pa. The dependence of μon the thickness h of the Ag film, which is used as a lubricant between Si₃N₄pin and SUS440C(Q) disk is expressed as μ=0.12 for W=10N and V=24mm/s when the film is thicker than 100nm. A brief discussion on these relations is presented from the viewpoint of the real contact area.
