The aim of this study was to analyze cohesion and word information among different types of questions in the English reading section of the College Scholastic Ability Tests (CSAT). The types of questions were divided into three categories: macro reading, micro reading, and indirect writing. Reading texts from 1994 to 2017 CSAT were analyzed by Coh-Metrix, an automated evaluation program of text and discourse. The findings of this study indicated that there were statistical differences among the three categories of questions for noun overlap, stem overlap, adversative and contrastive connective, additive connective, pronoun incidence, age of acquisition, concreteness for content word, imagability, and meaningfulness. The information of the findings bore pedagogic implications for developing textbooks, questions for CSAT, and reading strategies by students.

The study attempts to try a classification of tidal flats types by selecting indicators and go forward to suggest a management plan by tidal flats types. With several indicators selected and PSR(Pressure-State-Response) framework, the relationship between environmental changes and socioeconomic activities in tidal flats was investigated. Tidal flats types were consequently classified into three groups: Wetland Protection Area, Wetland Rehabilitation Area, and Wetland Use-coordination Area. Accordingly, 69 tidal flats were assigned into each groups by PSR analysis: 34 Wetlands Protection Areas, 26 Wetland Rehabilitation Areas, and 9 Wetland Use-coordination Areas. So the baseic management plan of tidal flats must be different by tidal flats and characteristics of region but basically it must give top priority to the sustainable use in the long term.

서비스마케팅문헌을 살펴보면 지각된 서비스품질 및 이에 대한 고객반응에 초점을 맞추어 이루어진 연구들이 많이 있다. 그러나 본 연구에서는 지각된 서비스품질이 실질적으로 서비스 구매자인 소비자의 재구매 행위와 어떤 인과관계가 있고 또한 로열티와는 어떤 인과성을 갖는지를 규명하는데 주력하였다. 아울러 이러한 인과성이 조절변수인 라이프스타일에 따라 어떤 차이가 발생하는지를 규명하고자 하였다. 지각된 서비스품질을 측정하는 있어서는 기존 SERVQUAL방식의 측정개념이 아닌 Johnson, Tsiros & Lancioni(1995)가 적용한 일반적 시스템 접근법(투입, 과정, 성과변수로 측정)을 활용하여 새롭게 접근하고자 노력하였다. 연구결과 지각된 서비스품질은 이를 구성하는 선행변수(투입요소와 과정 및 성과요소)와 긍정적인 정(+)의 인과관계를 나타내고 있으며, 특히 성과요소에 의해 서비스품질이 지각되는 경향이 매우 큰 것으로 분석되었다. 또한 지각된 서비스품질은 재구매 의사와 로열티에 긍정적인 영향을 미치고 있는 것으로 검증되었으며 이러한 모든 인과관계는 소비자들의 라이프스타일 유형에 따라 다르게 나타나고 있었다. 따라서 서비스산업에 있어 마케팅전략을 수립하는데 있어서도 유형적 제품과 마찬가지로 라이프스타일을 이용한 시장세분화 전략을 활용할 필요가 있다.

This study was to determine the relationship between nurse DISC personality types, self-efficacy, clinical performance. Data were collected from 302 nurses in 5 hospitals in K city. Data were analyzed using descriptive statistics, t-test, ANOVA, Pearson's correlation coefficient. With regard to self-efficacy and clinical performance, D type showed a higher score than type I type and S type. The lower region of the clinical performance showed the nursing process, nursing skills, higher score than the D Type S Type in professional development. With regard to personality and self-efficacy, and clinical performance, the type D (r=.56, p<.01), I type (r=.66, p<.01), S type (r=.6, p<.01) showed a positive correlation with type C (r=.52, p<.01). As shown by these results, each personality type has a different correlation with self-efficacy and clinical performance ability. This factor should be considered in the assignment of nurses to departments or individual training programs so that they can deliver the most effective job performance.

This study investigates the perception among college students on business ethics using Q methodology. The respondents are 34 business-major students attending a national university or a private university. The students are asked to choose words that, they think, would best represent business ethics. Results are as follows. First, we divide words related to business ethics into four types. and the explanatory power of type I, type II, type III and type IV are 25.72%, 10.87%, 6.49%, and 5.14% respectively, or 48.21% collectively. Type-I words are related to 'corporate social responsibility', type-II ones to 'sustainable management', type-III ones to 'integral management', and type-IV ones to 'responsible management', respectively. Results show that there is no significant difference in business ethics perceptions between the respondents from two different schools. Few of the sample students have ever taken a business ethics class before. The students perceive 'management philosophy and values', 'rules and regulations', and 'voluntary involvement of market participants in management,' as important factors to create a management environment for business ethics. In the $21^{st}$ century firms will be more sustainable by implementing business ethics. Therefore ethical management is not only a management philosophy but also a business strategy for a firm to survive.

Different physical processes, according to the atmospheric boundary layer types, were used in the Local Data Assimilation and Prediction System (LDAPS) of the Unified Model (UM) used by the Korea Meteorological Administration (KMA). Therefore, it is important to verify the atmospheric boundary layer types in the numerical model to improve the accuracy of the models performance. In this study, the atmospheric boundary layer types were verified using observational data. To classify the atmospheric boundary layer types, summer intensive observation data from radiosonde, flux observation instruments, Doppler wind Light Detection and Ranging(LIDAR) and ceilometer were used. A total number of 201 observation data points were analyzed over the course 61 days from June 18 to August 17, 2019. The most frequent types of differences between LDAPS and observed data were type 1 in LDAPS and type 2 in observed(each 53 times). And type 3 difference was observed in LDAPS and type 5 and 6 were observed 24 and 15 times, respectively. It was because of the simulation performance of the Cloud Physics such as that associated with the simulation of decoupled stratocumulus and cumulus cloud. Therefore, to improve the numerical model, cloud physics aspects should be considered in the atmospheric boundary layer type classification.

This study is for the quality improvement of water-sealing & reinforcement grouting in tunnel of the construction of the underground transportation network underneath the city. Existing tunnel grouting process did not technically utilize P~q~t charts fully. It is due to the absence of technical methods to decide how P~q~t charts change in the presence of trouble and what the change represents in grouting. There were no standards to decide which chart pattern represents which ground characteristics, how to categorize ground types, and how to take measures according to the standards. This paper studies on the grouting type, ground characteristics, ground type categorizing method, and countermeasures for both general and algorithm-processed grouting in soil and rock layer to address the aforementioned problems. Newly improved P~q~t charts from grouting in soil was categorized into six different types. Different characteristics and categorization method was developed for each type. Countermeasures for each type of grouting process were developed so that on-site application can be readily available. Improved P~q~t charts for rock layer also have six different types of grouting. Each type was given the countermeasures for rock layer grouting process for easier applications. Therefore, it is expected to be used through out the entire process of grouting from preparation to the last report of the water-sealing & reinforcement grouting in tunnel of the construction of the underground transportation network underneath the city.
