The purpose of this study is to investigate the relationship between clinical judgment and nursing performance based on myocardial infarction simulation applied to nursing students. Method: 39 fourth grade nursing students participated in this explanatory study with sampling of accommodations. The Lasater Clinical Judgment Rubric has been used in self-reported clinical trials and satisfaction with judging practices. Data were analyzed by descriptive statistics, t-test and Pearson's correlation coefficient using SPSS WIN 19. Results: Scenarios with myocardial infarction were scored by self-reported clinical judgment. Total mean score of clinical judgment and total mean value of clinical judgment is 4.17 ± 0.80. Correlation Between Variables After Simulation Practice is highly significant for providing positive clinical judgment and satisfaction with nursing performance. Conclusion: The simulation-based practice associated with adult nursing in myocardial infarction was useful for clinical judgment and nursing performance satisfaction, which improved the core basic skills of nursing students.

The eutrophication in lakes is caused by the inflow of excessive nitrogen and phosphorus, which are not only pollutants to reduce the value of water resource but also nutrients for algae growth that debases water quality. Several methods have been used to judge the eutrophication grades of lakes, but the judgment results can be different with one another even under same coditions because each method is different in judgment items and their standards. A method for overcoming the problem with the judgment of eutrophication grades is, therefore, developed in this study with the application of fuzzy theory. This method allows decision makers to represent the uncertainties (differences) of results by the existing judgment methods and also incorporate associated uncertainties directly into the judgment process, so the judgment results can be made that are more realistic and consistent than those made without taking uncertainty in account.

Many researchers are using the heterosis, heterobeltiosis and hybrid vigour over check parent value formulae to determine the hybrid vigour for animals, plants and silkworm breeding. These formulae are ideal for determine the hybrid vigour for the positive direction of single trait. It is difficult using these formulae for multiple traits. Suggested modification for cardinal formulae were made as well as suggestion new formula for determines hybrid vigour for multiple traits. Modifications of hybrid vigour were made to facilitate judgment of best hybrids under study for multiple traits. Nineteen local hybrids of mulberry silkworm were prepared for these investigations in addition the imported Bulgarian hybrid. Comparison between the cardinal and the modifications formulae were applied for thirteen economic characters. Nine positive and four negative direction characters were observed. Modified formulae make the judgment of heterobeltiosis, heterosis and hybrid vigour over check parent value very facilitate for positive and negative traits.

This study tested the validity of a three-factor model of the centrality of visual product aesthetics developed by Bloch, Brunel, and Arnold (2003) and explored the relationships between the centrality of visual product aesthetics and the relevant constructs. It was hypothesized that the path relationships including innovativeness and consumer independent judgment making are relevant constructs of the centrality of visual product aesthetics. Data were gathered by surveying university students in the Seoul metropolitan area (using convenience sampling) and 322 questionnaires were used in the statistical analysis. Correlation analysis, factor analysis, and regression analysis were conducted to analyze the data. The findings show the validity of the three factors (value, acumen, and response intensity) of the centrality of visual product aesthetics. Tests of the hypothesized path show that innovativeness influences the centrality of visual product aesthetics both directly and indirectly through consumer independent judgment making. Innovativeness positively influenced consumer independent judgment making and the three factors of the centrality of visual product aesthetics, whereas consumer independent judgment negatively influences the response intensity factor of the centrality of visual product aesthetics. The implications of these findings and suggestions for future study are also discussed.

This study aimed to investigate bag purchase behaviors according to materialism value. The subjects were 443 male and female adult consumers in their 20s to 50s. The research method was a survey, and the questionnaire consisted of questions on materialism value, bag purchase behaviors, and demographic characteristics. For data analysis, descriptive statistics, Cronbach's α, χ² test, factor analysis, cluster analysis, ANOVA, and Duncan's multiple range test were performed. The results of this study were as follows. First, materialism value was derived from three factors (happiness pursuit, possession-oriented, and success judgment). Second, subjects could be divided into three groups (happiness pursuit group, success judgment pursuit group, and immaterialism group) based on the materialism value variable. Third, the derived groups showed many differences in bag purchase behaviors. The happiness pursuit group considered all bag evaluation criteria factors (practicality, aesthetics, economy, symbolism) and bag purchasing information sources factors (mass media and personal sources) more than other groups, and showed a tendency to prefer select shops and complex shopping malls as bag purchasing places. In addition, the average annual cost and frequency of purchasing bags of this group were higher than those of other groups. The success judgment pursuit group considered symbolism as a bag evaluation criteria more than other groups, and considered personal sources as bag purchasing information sources more than mass media sources, and preferred luxury stores and department stores as bag purchasing places. On the other hand, the immaterialism group considered practicality and aesthetics as bag evaluation criteria and placed less importance on all information sources than other groups, and preferred Internet shopping malls as purchasing places. This group had the lowest average annual purchase cost and frequency among the three consumer groups. This study suggested that materialism value is a useful variable to segment male and female adult consumer markets effectively, and to understand the bag purchase behaviors of consumer groups divided by materialism value.

본 연구는 경호무도로서 점차 활성화되고 있는 공수도 수련을 탐색해 봄으로서 공수도가 경호무도로서 어떠한 가치를 갖는가를 정립하고자 한다. 연구방법은 문헌연구로 공수도 관련서적과 자료, 타무도를 경호무도로 활용한 선행 연구를 수집, 참고하였다. 경호무도는 일반적인 운동과는 달리 많은 노력과 숙련으로 실제상황을 대비하여 습득하는 무술로서 공격형이 아닌 방어형 무술이라고 할 수 있다. 경호업무에 있어서 한 번의 실수는 곧 경호대상자를 잃게 되는 결과를 초래하기에 경호의 존재가치가 무의미한 것으로 나타나기에 경호업무의 중요성은 날로 그 의미를 더해간다고 볼 수 있다. 이와 연관하여 본 연구자는 경호무도로서 공수도의 가치를 분류하면 다음과 같다. 첫째, 방어수단적 가치이다. 둘째, 신체적 가치이다. 셋째, 심리적 가치이다. 넷째, 기술적 가치이다. 다섯째 교육적 가치이다. 여섯째, 무도론적 가치이다. 이러한 경호무도로서의 공수도 수련의 가치는 세계인들의 나이와 인종 그리고 종교에 관계없이 공경호와 사경호를 위한 경호무도로서 발전되어 가고 있다.

가스계량기의 검침방식이 발전하면서 원격검침이 가능한 스마트 가스 계량기(누출점검용 계량기 및 다기능 안전 계량기)가 사용되고 있다. 이러한 계량기는 부가기능으로 수집하는 유량 및 압력 데이터를 활용하여 누출 판단을 하는 기능이 있다. 유량 데이터를 이용한 누출판단 기능은 실제 현장에서 유효한 사례가 있지만 압력 데이터 기반 누출 판단 기준은 누출로 인한 압력 값 변화뿐만 아니라 여러 요인(정압기 압력 크기, 인접 계량기 연계, 인접 주택 사용량, 계량기 위치 등)으로 압력 크기 변화(레벨)가 있는 문제점이 있다. 본 논문에서는 스마트 가스계량기에서 수집되는 압력데이터를 활용하여 누출여부를 판단 할 수 있는 기법으로 압력 데이터 전처리 방법과 누출 여부 관련 압력 값 범위 기준, 누출판단 기법 및 적용 사례 검증을 통해 개발하였다.

This paper presents a new method for forecasting construction project cost and time at completion or at any intermediate time horizon of the project duration. The method is designed to overcome identified limitations of current applications of earned value method in forecasting project cost and time. The proposed method usesfuzzy set theory to model uncertainties associated with project performance and it integrates the earned value technique and the contractors' judgement. The fuzzy set theory is applied as an alternative approach to deterministic and probabilistic methods. Using fuzzy set theory allows contractors to: (1) perform risk analysis for different scenarios of project performance indices, and (2) perform different scenarios expressing vagueness and imprecision of forecasted project cost and time using a set of measures and indices. Unlike the current applications of Earned Value Method(EVM), The proposed method has a numberof interesting features: (1) integrating contractors' judgement in forecasting project performance; (2) enabling contractors to evaluate the risk associated with cost overrun in much simpler method comparing with that of simulation, and (3) accounting for uncertainties involved in the forecasting project cost.

Color chart area is automatically extracted in image that captured a crop such as fruits with the color chart, and an approximation formula is obtained for the change in feature value of the color indexes. Comparison is made with the color value of the crop area, and the growing degree is assessed according to the correlation. Using a compact PC equipped with the program, image of fruits is captured, and the output value obtained by the system is compared to the rating by expert. In the automatic recognition of the color chart out of doors, the complete color indexes is correctly acquired in 22 of 29 images. And indoors, they are correctly acquired in all of 34 images. In the color value judgment of the Japanese pear, indoors, 32 of 34 images is within 1.0 of the judgment error (compared the value read off by experts), the average error is about 0.5. These results indicate a practicable value.
