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.

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.

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).

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.

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.

The purpose of this study is to invastigate the methods of privatization in Former East Germany. The contents of the research are summarized as follows: Trust administration agency executed the privatization of state enterprise and private-ownership of land till its task is completed on Dec. 31, 1994. Executing policies are the eviction of the land to original possessor and the method of sales to general public. But, the problems such as ambiguity of legal possession, the lack of management personnel and legal basis are imposed in the eviction method and there are the problems of low purchasing income, outflow of investment capital from capital market and rare potential to purchase the objects by the residents in the former East Germany with weak economic strength in the methods of sale. Moreover, the income from sale is low due to the factors inherent in the measures of the privatization and private management policies of trust administration agency such as remaining of economic structure of socialism, disagreement of stock-flow, credit limitation of purchaser and etc., and the sale of privatization objects is delayed. The methods to settle the above problems and foster the conversion of economic structure in the former East Germany region are as follows. In fostering methods of privatization and private-ownership of land, the problem of fund raising and the resurrection of enterprise which is the decisive weakness of free distribution should be settled. To overcome these problems, the suggestion of proportion division pattern can be theoretically referred. The core of this pattern is that the proportion of enterprise is distributed to investors and people, but government divides the proportion of enterprise which is equivalent to its own value of enterprise which supported for technical accumulation and its normalization to investors and the reamining is distributed to people not to government. This Pattern has such advantages as (1) possibility of early income supply of residents, (2) overcome of credit limitation, (3) solution of flow, stock problem, (4) relaxation of the eviction principle of tenant to original possessor and (5) availability of it to delayed negotiation of wage increase.

Excretory urography is a type of contrast study used to verify and localize upper urinary tract disease. It is an inexpensive and easy way to visualize of anatomic and functional status of the kidney and has been used as a primary imaging modality for the evaluation of urinary tract abnormalities. We describe urological signs of 7 dogs who examined with excretory urography and ultrasonography. Six cases were referred to veterinary medical teaching hospital. Chungnam national university (VMTH, CNU) to evaluate renal function after the treatment for renal failure and one case was referred showing hematuria. In case 1, 2 and 4, blood test and urinalysis was normal and the results of excretory urography presented that renal function were normal range. In case 3, the results of urinalysis, ultrasonography, and excretory urography except blood test presented abnormal kidney and hydronephrosis was diagnosed. In case 5 and 6, blood test, urinalysis, ultrasonography and excretory urography indicated renal failure. In case 7, blood test, urinalysis and ultrasonography presented partially abnormal signs, however, the results of excretory urography was normal range.
