Recently, a new infectious disease, COVID-19, has been spreading not only in Korea but around the world. As a result, the Korean government raised the level of infectious disease crisis alerts to a serious level on February 23, 2020. The purpose of this study is to apply the situational theory of publics to publics segmentation according to the issuance of a crisis alert and to suggest ways to improve the crisis alert system. To this end, the level of public perception on crisis alerts was checked. The verification confirmed that the situational theory of publics is a suitable theoretical framework for analyzing the communication behaviors of the public toward crisis alerts. As a result of the public segmentation, 42.7% were classified as active publics. Based on this, it was suggested to reorganize the crisis alert system as a system for communicating with the public.

The purpose of this study is to analyze the biotope characteristics of Korean cities and set up biotope type structures for Korean cities based on biotope type classification, dominant biotope type, city's human and nature environmental characteristics and cluster analysis. The findings of the study are summarized as follows: First, regarding the analysis of biotope type classification, cities showed differences in terms of the standard of biotope classification and classification hierarchy. Next, the analysis of dominant biotope types showed the type of forest represents the largest area in most cities. Moreover, a city's characteristic analysis revealed large differences between cities. As a result of cluster analysis, cities were classified into five clusters overall. First, Cluster A showed a lower population level and urbanization level. Unlike other cities, Cluster A revealed that it has the largest percentage of agricultural areas. Cluster C showed very high levels in terms of population amount and urbanization conditions was named the 'Large-sized metropolitan cities-center of forest biotope area' based on it's characteristics. The findings of this study as summarized above are considered to play an important role in enabling detailed classification and preservation of biotope types fit for the characteristics of cities and minimizing the confusion caused by different biotope mapping methods when revising and complementing biotope maps.

This research thesis measured potential housing development of 250 'subway station areas' around Seoul Metropolitain Region, with the use of added weighting and data of each indicator based on AHP. The analysis was conducted on the ranking of the development of 'subway station areas' on the basis of measurement results of potential housing development along with the analysis on characteristics of 'subway station areas' in daily life zone. Cluster analysis-oriented analytic measurement results suggested that 'subway station areas' in Seoul Metropolitain Region can be grouped into five clusters: Cluster 1 and Cluster 2 were populated with 'reservation areas' for outside and inside urban development, respectively scoring low all in housing development pressure and capacity. Cluster 3 was populated with 'development maintenance areas', scoring low in housing development pressure but high all in housing development capacity. Cluster 4 was populated with 'development facilitation areas', scored high all in housing development pressure and capacity. Cluster 5 was populated with 'development control areas' scoring high in housing development pressure but low in housing development capacity.

The purpose of this study is to examine the utilization of university libraries Web OPACs. As a sample group, 51 university libraries are selected and classified to 9 common types. The nine types of Web OPACs are analyzed； operational characteristics, access points, search types, output formats and help functions. The results of this study can be used towards the interface designs of Web OPACS.

The purpose of this study is to suggest the guideline by analysing and categorizing the case of sharing economy service especially the co-working and co-living space based on Europe. I did some literature research followed with evaluation of theoretical backgrounds, present conditions. Also, Some case research based on the keyword of 4th industrial revolution and the space categorized by their characteristics. The result indicate that co-working and co-living space's features correlated with their characteristics of the location and birth of digital nomad life. Each space has their flat-form community for the needs of closer cooperation between the user and user in common. I expect this study will become a good resource for upgrading domestic co-working and co-living space and also I hope that this study can guide follow-up next studies.

국내 원전에 신뢰도 기반 정비(RCM : Reliability Centered Maintenance) 기법을 도입하기 위해 수행하고 있는 영광 1,2호기 시법계통 RCM 분석에서 관련 기기의 고장데이터를 RCM 분석 방법론에 따라 분석하였다. 본 논문에서는 작업의뢰서와 작업보고서 기록내용을 토대로 지배적인 고장모드 및 다빈도 고장발생 기기를 파악하여 고장원인을 분석하였으며, 기기 유형으로 분류하여 고장들을 분석하였다. 분석결과 지배적인 고장모드는 EPRI에서 분류한 고장모드에 모두 포함되었으며, 고장빈도가 높은 기기의 고장원인은 운전환경, 사용유체, 운전형태, 기기 형식 등에 따라 고장메커니즘이 다르게 나타나는 것으로 분석되었다. 기기 유형으로 분류하여 고장모드별로 고장율을 분석한 결과 미국의 Generic Data(IEEE Std 500-1984)와 근소한 차이를 보이거나 약간 낮은 것으로 분석되었으며, 고장율이 높은 기기 유형을 단위 기기별로 세분화하여 분석한 결과 공기구동 조절벨브의 외부누설 고장율은 1.10E-06 이지만 충전유량 조절밸브의 고장율은 1.70E-05로서 약 10배 정도로 고장율이 높은 것으로 분석되었다. 기기별로 세분화한 고장을 분석 결과는 시범계통 RCM 분석시 고장모드 영향분석(FMEA. Failure Mode and Effective Analysis) 단계에서 필수기기를 선정하는 하나의 인자로 활용하였으며, 고장율의 역수로 구한 고장간 평균시간(MTBF:Mean Time Between Failure)은 정비주기 선정시 기초데이터로 활용된다.

This study designed to know subjective structure about type of coping with stress of nursing students using Q-methodology. The statement positions on the sorting continuum were scored from +4(representing the highest level of agreement) through 0(at the neutral position on the continuum) through -4(representing the highest level of disagreement). Factor analysis of the data was undertaken using PC QUANL software to determine if any patterns were discernible. The four types extracted eigenvalues greater than 1.0 and explained approximately 52.14% of the variation in responses(31.73, 10.13, 5.73 and 4.65% respectively).: (1) Positive resolve type, (2) Ignore problem type, (3) Self resolution type and (4) Conversation type. The study results can be utilized in both an effective nursing education and clinical practice.

This study was conducted to compare the self-leadership strategies and locus of control between the problem-solving styles in the Korean engineering college students. Creative problem-solving styles were identified based on the three dimensions. The results of the two-way analysis of variances indicated the main effects of problem-solving styles; each problem-solving style had unique characteristics in relation to self-leadership strategies and locus of control. There were neither main effects of sex nor interaction effects of problem-solving styles and sex. It would be useful to provide the engineering students with the specialized self-leadership training program based on the problem-solving styles.
