In this paper, we consider relationship of the monastic mathematics and the arts of the middle ages. Because mathematics and arts are effects of the spirit of the ages. Here, we concern with the Rome and the religion of Christ. Next, we think of the bible and Christian doctrine and then compare with Christian arts and arts of the customs of the middle ages. The middle ages is the period of women's inequality according to the feudal system. So we investigate the correlation of the christianity, arts of the middle ages, women's inequality and monastic mathematics which is worthless in mathematics history.

매일 새롭게 생기는 웹 페이지 수가 수천만 개, 온라인 문서들의 수가 수십억 개에 이르게 되자, 웹 사이트를 설계함에 있어서 웹 서버 로그 파일에 기록된 사용자의 행동을 분석하는 것이 중요한 부분이 되어가고 있다. 분석가들은 전체 웹 사이트에서 사용자 행동의 완전한 개요를 알기 원하기 때문에 고객이 방문했던 모든 다른 웹 서버를 통하여 사용자의 패스(path)를 다시 수집해야만 한다. 본 연구에서는 모든 로그 파일을 연결해서 방문했던 곳을 재구성하는 향상된 데이터 전처리 방법에 의하여 실험을 하여 로그 파일 크기를 감소시키게 되어 데이터 전처리의 성능이 향상되었음을 보였다.

The purpose of the study was to find out design problems of grand chapel of the Protestant church and to set analysis frame based on theoretical study on abstract symbolism and investigate cases and to give reference of abstract symbolism expression of design of the chapel. The findings were as follow: Introduction of the light was found to be the most outstanding among abstract symbolic factors, and metaphor was commonly used to express abstract symbols. First, 1) Introduction of the light was found to be the most outstanding at application of abstract symbolic factor of modern Protestant church to be the highest among pastors, office bearers, believers and non-Christians. 2) The metaphor was found to be the most noticeable among abstract symbolic expressions. Second, the findings of questionnaire survey was: The findings of questionnaire of not only abstract symbolic expression factor but also symbolic expression method was not to cognize ideas of pastor, office bearers, believers and designers often. This was because abstract symbolism was made from point of view of designers. Therefore, abstract symbolic expression factors of grand chapel of modern Protestant church, for instance, effective introduction of the light, light quoting the Bible sayings, material, color and shapes, etc should be used with metaphor and symmetry to give Christians value of symbol and to hide meaning of symbolic values to non-Christians who do not know contents of the Bible.

Purpose: The purpose of this study was to investigate the present status of falls among inpatients in general hospitals and to identify the fall risk factors that reflect the characteristics of domestic hospitals. Methods: Data were collected between December 15, 2016 and January 15, 2017 from 32 Korean hospitals having 500 or more beds. First, 42 risk factors were extracted based on literature review and expert opinions. Then the importance of each factor was evaluated by 223 nurses from medical and surgical adult ward and intensive care units in 40 hospitals. Results: The incidence rate of falls in 18 hospitals was 3.87 per 1,000 total discharged patients and 0.55 per 1,000 patient-days, and the rate of injury-related falls was 40.5%. Major risk factors for falling were identified as the following: being over 65 years of age, history of falls during admission, physical mobility disorders requiring assistance, physical factors (dizziness or vertigo, unstable gait, general weakness, walking aids, visual problems), cognitive factors (delirium, lack of understanding on limitations), neurological disease, CNS medications Conclusion: The findings provide information that can be in the development of a fall risk assessment tool for inpatients in general hospitals in Korea.

All human being can't exist by oneself. That is, all human being depend on intimate attachment for their survival. Physical and psychological powers and control functions are prerequisites for one's survival and these serve important functions in interpersonal relationships. There are two kinds of powers and controls. One is positive power which helps one survive effectively. Another one is negative power which disturbs one's effective survival. Introspection is one of the positive power and most important process in understanding oneself and others. Thus, the purpose of this study is to elucidate the physical and psychological meaning of the characteristics of water and based on this meaning, to suggest one way of introspection. The authors reviewed the precept of water which is described in Bible and oriental classical books such as 'the Analects of Confuicus(論語)', 'Tao Te Ching(道德經)', 'Mencius(맹자)', 'Chronicle(史記)', 'The Doctrine of the Mean(中庸)', 'University(大學)'. The author also reviewed 'The History of Three Countries(삼국사기, 삼국유사)', 'The Precept of Religion', and 'the modern poems' which includes the symbolic meaning of water. The results are summarized as follows：1) The flow of water itself is the expression of introspection. Because, water does not flow without filling a puddle. 2) Water is the symbol of 'Immortality'. 3) Water symbolizes 'Modesty and Trust'. 4) Water is the symbol of 'Freedom from Greed'. 5) Water symbolizes 'Goodness and Beauty'. 6) Water symbolizes 'Naturality and Love'. Immortality, Modesty and Trust, Freedom from Greed, Goodness and Beauty, and Naturality and Love are eternal, universal values which all human should seek and achieve. By the process of introspection through the symbolic meaning of water, we can achieve these positive aspects of human mind and spirit.

Purpose: The purpose of this study was to test the predictive validity of the Fall Assessment Scale-Korean version (FAS-K) and to find the most appropriate cutoff score to screen high-risk fall groups in adult patients in general hospitals in Korea. Methods: We performed a prospective evaluation study in medical and surgical ward patients at two major general hospitals in Seoul. Data were collected from Nov. 1, 2018 to Feb. 28, 2019, nurses performed 651 observation series. The researcher measured the fall risk assessment score by applying FAS-K, MFS (Morse Fall Scale), and JHFRAT (Johns Hopkins Hospital Fall Risk Assessment tool) to the patients twice a week between 10 am and 12 noon. Data were analyzed using Pearson's corelation coefficients, and the sensitivity, specificity, predictive value, and the area under the curve (AUC) of the three tools. Results: The FAS-K was positively correlated with the MFS (r=.70, p<.001) and the JHFRAT (r=.82, p<.001). According to the receiver operating characteristics (ROC) curve analysis of the FAS-K, sensitivity, specificity, and positive and negative prediction values were 85.3%, 49.4%, 8.5%, and 98.4%, respectively, when the FAS-K score was 4. Therefore, the cut-off score of the FAS-K to identify groups with high fall risk was 4. Conclusion: The FAS-K is a valid tool for measuring fall risk in adult inpatients. In addition, the FAS-K score, 4, can be used to identify high-risk fall groups and know specific points in time to provide active interventions to prevent falls.

Purpose: The purpose of this study was to develop a reliable and valid pain assessment tool suitable for critically ill patients with communication problem in Korean intensive care unit. Methods: This pain assessment tool, Critical Care Non-verbal Pain Scale (CNPS), was developed based on review of national and international researches. Data were collected from ten intensive care units at five major general hospitals in Seoul. Reliability and validity were tested during performance of position change and endotracheal suctioning. Pain was measured before, during, and 20 minutes after the two procedures. Results: Interrater reliability of the CNPS was analyzed by ICC (Intraclass correlation coefficients). ICC values were significant from .833 to .883. Significant correlation between the FPS (Face Pain Scale) scores and the CNPS scores verified concurrent validity of the CNPS. For position change, CNPS scores increased significantly between before and during (t=-23.399, p<.001) and decreased significantly between during and 20 minutes after (t=22.760, p<.001). For endotracheal suctioning, CNPS scores increased significantly between before and during (t=-29.064, p<.001) and significantly decreased between during and 20 minutes after (t=28.194, p<.001), verifying construct validity of the CNPS. Conclusion: Results indicate that the CNPS can be used to assess pain of critically ill patients who have communication problem.
