Purpose: This study was performed to provide data for improvement in clinical practice education through analyzing the status of clinical practice education in maternity nursing in four year course nursing schools in Korea. Method: Analyzed subjects were 43 schools out of 53 four year course nursing schools in Korea. Result: Credits in theory and clinical practice are on the decline. The relationship between goals and areas of clinical practice was not sufficient. The department was not efficient in meeting the demands between theory and practice. The number of students in a group according to clinical areas were thoughtfully assigned, and clinical practice was performed based on real situations. Instructors for clinical practice used practice lecturers, part-time lecturers, preceptors, and assistant instructors including faculty. Methods of practice education and evaluation were varied. Conclusion: A suitable philosophy and goals of clinical practice education maternity nursing should be established at this point in time. Furthermore, a study should be performed to analyze the relationship between goals and contents of clinical practice for maternity nursing. In addition, a standardized tool should be developed to evaluate clinical practice.

As measures for protecting users and ensuring security of electronic financial transactions, such as online banking, financial institutions in South Korea have implemented network segregation policies. However, a revision of such domain-centered standardized network segregation policies has been increasingly requested because of: 1) increased demand for remote work due to changes resulting from COVID-19 pandemic; and 2) the difficulty of applying new technologies of fintech companies based on information and communications technologies (ICTs) such as cloud services. Therefore, in this study, problems of the remote work environment arising from the network segregation policy currently applied to the financial sector in South Korea and those from the application of new ICTs such as fintech technology have been investigated. In addition, internal network protection policies of foreign financial sectors, such as those of the United States, United Kingdom, European Union, and Russia, and internal network protection policies of non-financial sectors, such as control systems, have been analyzed. As measures for the effective improvement of the current network segregation policy, we propose a policy change from domain-based to data-centric network segregation. Furthermore, to resolve threats of hacking at remote work, recently emerging as a global problem due to COVID-19 pandemic, a standard model for remote work system development applicable to financial companies and a reinforced terminal security model are presented, and an alternative control method applicable when network segregation is not applied is proposed.

우리나라에선 크고 작은 가뭄 피해가 자주 일어나고 있으며 최근엔 유래 없는 다년가뭄이 발생하면서 가뭄에 대한 경각심이 커지고 있다. 가뭄에 적절하게 대응하여 피해를 경감시키기 위해서는 신뢰도 높은 가뭄 예측이 선행되어야 한다. 이에 본 연구는 앙상블 예측과 베이즈이론(Bayes' theorem)을 수문학적 가뭄지수 중 하나인 SRI(Standardized Runoff Index)에 적용해 가뭄 확률 전망을 실시했으며 이를 EDP(Ensemble Drought Prediction)라고 칭하였다. 국내 8개 댐유역에서 EDP를 생성하고 개선하는 과정은 다음과 같이 진행된다. 우선 TANK모형을 활용한 1개월 선행 유량 예측(Ensemble Streamflow Prediction, ESP)의 결과를 SRI로 변환하여 EDP 확률분포를 생성한다. 그런 다음, EDP를 개선하기 위해 그 기초인 ESP에서 미흡한 토양수분 초기조건을 보완하고자 베이즈이론을 활용했다. APCC(APEC Climate Center)의 위성 관측 SMI(Soil Moisture Index) 자료로 SRI와의 회귀식을 구축, 이를 우도함수로 정의해 사전 EDP 분포를 업데이트한 EDP+ 확률분포를 생성했다. 그 결과, EDP와 EDP+ 모두 심도가 깊은 가뭄을 전망할수록 예측력이 기후학적 예측보다 좋지 않았다. 그럼에도 우도함수로 사용한 회귀식의 정확도가 높을수록 EDP+의 정확도도 향상되는 경향이 나타났으며, 이는 베이즈이론을 사용한다면 가뭄 확률 전망을 개선할 수 있다는 것을 의미하고 있다. 하지만, 확정 전망 정확도는 확률 전망 정확도와는 관계가 없었는데 이는 확정 전망과 확률 전망이 본질적으로 다르기 때문인 것으로 사료된다.

CO2 emission makes up more than 80% of whole green gas. Therefore CO2 is recognized as the main culprit of global warming. IPCC (Intergovernmental Panel on Climate Change) is advising the 3 methods measuring CO2 emission. TIER1 is measured CO2 emission by criteria the energy consumption, TIER2 measure by criteria the emission factor according to the emission control technique each kind of vehicle, TIER3 is measured by criteria the distance each kind of vehicle. Currently, the most of CO2 emission measurement is used by TIER1. But it is not standardized that CO2 emission measurement method have the factor as work condition each distance. Specially, it is not suggest that methodology has the condition changing load of equipment according to site condition and the same position work as construction equipment. So, this study is suggested the CO2 emission measurement methodology of construction equipment.

In recent years, the population structure has been changed by the progresses of 6th-industrialization and transportation in farming areas. This study aims to suggest a regional development plan of farming areas in accordance with the demographic changes. Population structure indicators were derived from previous studies and literature review in order to identify the types of farming areas. Demographic indicators separated to depopulation and population growth in farming areas through a standardized scoring method. This research found that the division of economy is not only the most important division in any other regional development divisions but also necessary to develop new sources of non-farm income through traditional culture, natural environment. In the social division, it is necessary to secure the facilities for the formation of a sense of community to multicultural families and existing residents in farming areas. In the environmental division, it is desirable to improve the quality and satisfaction of life for residents such as the sidewalk and park that utilize ecological environment, culture, history for both depopulation and population region. In the physical division, there is a need for improvement of the facilities of basic living infrastructure service such as roads, water supply and sewerage systems. In the institution division, sustainable financial support of the central government policy for farming areas is crucial for the improvement of residential environment in the farming areas of depopulation and population region.

While institutional matters such as improvement on Basic Guidelines for Construction Safety are greatly concerned to reduce falling accidents at construction sites, there are short of studies on how to practically predict accident signs at construction sites and to preemptively prevent them. As one of existing accident prevention methods, it was attempted to build the early warning system based on standardized accident scenarios to control the situations. However, the investment cost was too high depending on the site situation, and it did not help construction workers directly since it was developed to mainly provide support operational work support to safety managers. In the long run, it would be possible to develop the augmented reality based accident prevention method from the worker perspective by extracting product information from BIM, visually rendering it along with site installation materials term and comparing it with the site situation. However, to make this method effective, the BIM model should be implemented first and the technology that can promptly process site situations should be introduced. Accordingly, it is necessary to identify risk signs through lightweight image processing to promptly respond only with currently available resources. In this study, it was intended to propose the system concept that identified potential risk factors of falling accidents by histogram equalization, which was known as the fastest image processing method presently, used visual words, which could enhance model classification by wording image records, to determine the risk factors and notified them to the work manager.

This study was performed to compare manual liquid-based preparation with conventional Papanicolaou tests in view of the cytologic diagnoses and specimen adequacy. The specimens of 5,979 women from 33 local clinics and 1 general hospital were prepared by both manual liquid-based preparation and conventional Papanicolaou test. The cytologic diagnoses and specimen adequacy were evaluated in Department of Fathology in Kyoungpook National University School of Medicine. A conventional Papanicolaou test was always prepared first, after that residual material on the sampling device was rinsed into a liquid preservative, and then thin-layer slides were prepared using manual method of liquid-based cervicovaginal cytology. Conventional and liquid-based slides were read independently, and cytologic diagnoses and specimen adequacy were classified using the Bethesda System. Of the cases, 5,763 (96.3%,) had the same interpretation, and there was no significant diagnostic difference in 5,853 (97.8%) cases. When evaluating cases with more than one diagnostic class difference, the manual liquid-based preparation demonstrated a statistically significant overall improvement (2.1%) in the detection of squamous intraepithelial lesion and invasive cancer. Using manual method of liquid-based preparation, there was 14.1%, reduction in unsatisfactory slides through excellent cellular presentation. In conclusion, the manual liquid-based preparation produces standardized quality, superior sensitivity and improved adequacy as compared to the conventional method.

Background : This study aimed at identifying the effect of the standardized protocol on lowering the incidence of the ventilator associated pneumonia(VAP). Methods : The standard protocol focusing on decreasing VAP was made and applied at 5 ICUs (Medical ICU, surgical ICU, Respiratory ICU, Neonatal ICU, Pediatric ICU) in a university affiliated tertiary hospital, from April 1, 2000 to Oct 31, 2000. The protocol involved 3 parts : hand washing, the suctioning method and ventilator circuit management. All the nursing personnel received intensive education which was consisted of lecture, video film and demonstration. 176 nurses reported the performance of handwashing pre and post intervention. And randomly selected 15 nurses were observed by charge nurse and the handwashing practice was analyzed pre and post intervention. The incidence of VAP was compared with the former year incidence. Results : The self reported frequency of hand washing increased. In the direct observation of handwashing, the frequency, time, thoroughness of hand washing during 8 hours day duty was found to be improved. The frequency was increased from 1.1 time to 4.1 times; the time was improved from 1.7 seconds to 5.7 seconds and the thoroughness of the washing practice was from 0.2 times to 3.0 times respectively (p<0.001). The incidence of VAP decreased from at a rate of 15.63 number of case per 1,000 ventilator-day (April 1~August 31, 1999) to 7.23 number of case per 1,000 ventilator-days(April 1~Oct 31, 2000)(P<0.001). Conclusion : We developed the protocols which included hand washing, the suctioning method, and ventilator circuit management. Through the implementation of the protocol, the performance of hand washing improved and the VAP incidence rate in ICU was decreased.

The present study was conducted to develop a standardized job description for clinical dietitians working in hospitals. A developing curriculum (DACUM) method was used for the job analysis of clinical dietitians. Based on DACUM analysis with 14 members, including clinical dietitians and professors majoring in clinical nutrition and job analysis, information on the duties, tasks, and task elements of clinical dietitians was determined. To verify the job descriptions derived from DACUM analysis, a total of 46 tertiary and general hospitals with over 500 beds were recruited for the survey. The final developed job description for clinical dietitians included 7 duties, 27 tasks, and 93 task elements. The duties consisted of nutritional assessment, nutrition diagnosis, nutrition intervention, nutrition monitoring evaluation, consultation cooperation, nutrition research, and self-development. The mean scores of perceived importance, performance, and difficulty on the clinical dietitian's task elements (out of a maximum score of 5.0) were 4.5, 3.7, and 3.5, respectively, with significant differences between the items (P<0.001). The perceived importance and performance grid of clinical dietitian's tasks showed that "construction and maintenance of collaboration" (E2) and "activity of quality improvement" (F1) received relatively low scores for performance despite their high importance scores; thus the performance of these tasks requires significant improvement. In conclusion, the job descriptions of clinical dietitians developed from this study are useful for the qualitative improvement of clinical nutrition services in hospitals.

Understandings of adsorption characteristic of interface are very important in several advanced materials processes, related to NT and BT technology. Volumetric gas adsorption method, suitable for absolute measurements, is regarded as the standardized measurement technique for specific surface area. In order to verify the reliability of commercial equipments, certified reference materials (called CRM) of specific surface area are developed and evaluated its uncertainty factors by standard equipment which has traceability to SI units. Specific surface areas of developed materials are $10.72{\pm}0.46m^2g^{-1}$ for silicon nitride powders and $149.50{\pm}3.44m^2g^{-1}$ for alumina. These disseminations of CRMs would result in improved reliability chains in industrial processes, and lead eventually to contribution to productivity improvement, quality management, safety evaluation, and possibly to new material development.
