Ratings and reviews, despite their growing influence on restaurants' sales and reputation, entail a few limitations due to the burgeoning of reviews and inaccuracies in rating systems. This study explores the texts in reviews and ratings of a delivery application and discovers ways to elevate review credibility and usefulness. Through a text mining method, we concluded that the delivery application 'Yogiyo' has (1) a five-star oriented rating dispersion, (2) a strong positive correlation between rating factors (taste, quantity, and delivery) and (3) distinct part of speech and morpheme proportions depending on review polarity. We created a chicken-specialized negative word dictionary under four main topics and 20 sub-topic classifications after extracting a total of 367 negative words. We provide insights on how the research on delivery app reviews should progress, centered on fried chicken reviews.

General hospitals have being under the influence of various and specific environment of electromagnetic field. The factors are development of medical electric equipment and device with enlarged functional demands, in high power and multi-frequency. It has all of both faces, EMI(electromagnetic interference) and EMS(electromagnetic susceptibility). In additional, expansion of personal communication system(cellular phone) has many unreliable factor of using time and area, making noise of electromagnetic fields. We studied actual conditions of EMI in the medical site, where is numerous medical equipment, especially central operation room and ICU(intensive care unit), AKR(artificial kidney room : hemo-dialysis unit), etc. The influence, most of medical equipments made electromagnetic nosie has various factors in its band of frequency, harmonics and strength. In the experimental use of electro-surgical unit and cellular phone, noticeable and considerable noise of eletromagnetic fields were measured. All of that can make trouble and errors on the steadiness of bioelectrical devices. In conclusion, It is necessary to reconsiderations of reallocating EMI source vs. EMS factor, and set to definite forbiding area of using cellular phone. For maintenance of steady normal conditions, in spite of existing any other legal standards of safty level, it need considering all of alternative electromagnetic situations on a case-by-case basis.

The purpose of this study was to identify whether environmental evidence and experiences respectively could affect brand attitude in Korean restaurant. Also, this study investigated a moderating effect of brand reputation in the causal relationship between environmental evidence and brand attitude and, between experiences and brand attitude. Questionnaires were given to a sample of customers who visited branches of H or B Korean restaurant brand which ranked within 20th in sales volume among Korean restaurant brands. A total of 353 questionnaires were analyzed with hierarchical regression analysis using SPSS/PC+. There were four major empirical research findings. Firstly, among components of environmental evidence, space, aesthetics, cleanliness and pleasance affected brand attitude. Secondly, all components of experiences, act, relate, think and feel affected brand attitude. Thirdly, brand reputation had a moderating role in the causal relationship between aesthetics dimension and brand attitude, but space, cleanliness, convenience and pleasance dimensions did not have a moderating role of brand reputation to the relationship of brand attitude. Fourth, brand reputation had a moderating role in the causal relationship between act and brand attitude, but relate, think and feel didn't have a moderating role of brand reputation to the relationship of brand attitude. Based on these findings, marketers of Korean restaurants were recommended to strengthen environmental evidence and experiences. Also, they are advised to strengthen brand reputation with use of marketing.

카툰 렌더링 그래픽을 기반으로 한 온라인 RPG 게임인 마비노기에서는 게임이용자들이 염색 시스템을 통하여 의복아이템에 자신들이 원하는 색을 자유롭게 표현할 수 있다. 마비노기에서 색에 관련된 주목할 만한 현상은유행색이 존재하고 색에 따라 같은 아이템의 가격이 달라진다는 점이다. 유행색이 존재하는 것은 현실과 비슷하지만 같은 아이템이 색에 따라 가격이 달라지는 것은 현실에서는 보기 드물다. 이는 현실과 비슷하면서도 심리적인 속성이 다른 사이버공간만의 특징이라고 생각해 볼 수 있다. 따라서 마비노기에서 게임이용자들이 색을 선택하고 사용할 때 작용하는 심리기제가 존재할 것이라고 가정해 볼 수 있다. 이에 본 연구에서는 마비노기에서 색 선택 행동의 심리적 유형을 확인하고 유형별 특징을 알아보기 위해 자아존중감을 측정하였다. 예비 조사를 통해 게임이용자 20명과 온라인 인터뷰를 실시하여 색 사용 경험을 추출하고, 추출한 경험을 바탕으로 18문항의 색 선택 행동 문항을 구성하였다. 본 조사에서는 온라인 설문으로 129명의 게임이용자를 대상으로 색 선택 행동과 자아존중감을 측정하였다. 연구 결과 색 선택 행동은 4개의 요인-색채 둔감성, 유행추종, 개성표현, 캐릭터이미지와의 적합성-으로 구분되었다. 색선택 행동 4개의 하위 요인을 기준으로 군집분석한 결과 색 선택 행동 유형은 각각 색 분화형, 유행추종형, 색 둔감형으로 구분되었다. 색 선택 행동 유형과 자아존중감과의 관계에서는 자아존중감 하위 범주 중 부정적인 자기평가, 타인의 의견에 대한 걱정, 의존성의 세 가지 하위 범주에서 색 선택 행동 유형에 따른 차이가 유의미하게 나타났다. 한편 자의식 차원에서는 색 선택 행동 유형간 유의미한 차이가 발견되지 않았다. 유행추종형은 다른 두 유형에 비해 상대적으로 자아존중감 수준이 낮음을 확인할 수 있었다. 반대로 색 둔감형은 다른 두 유형에 비해 상대적으로 자아 존중감 수준이 높았다. 색 분화형은 유행추종형과 색 둔감형의 중간 수준의 자아존중감을 볼 수 있었다. 유행추종형은 자기의 외부에서, 색 둔감형은 자기의 내부에서 색과 관련된 자신에 대한 가치감의 소재와 근원을 찾는 특성이 있다고 해석할 수 있다. 본 연구는 온라인 RPG 게임에서 게임이용자들의 색 선택의 심리적 기제를 확인하고 색 선택 유형별로 자아존중감과의 관계를 확인함으로써 색 선택 행동의 심리적 기제를 밝히려는 기초연구라는 점에 의의가 있다. 추후에는 게임이용자들의 색 선택 행동을 보다 포괄적으로 이해하기 위해 게임이용자들이 가지고 있는 공통적인 색이미지와 개별적인 색이미지 및 색이미지의 심리적 구조를 알아보기 위한 색채감성연구가 필요할 것이다. 이러한 연구들은 게임을 제작할 때 캐릭터 디자인과 아이템 디자인에 어떠한 색을 사용해야 되는지 방향을 설정하는데 도움을 줄 수 있을 것이다.

Looking at multimedia education contents from a design point of view, the instructor's design model may differ from the child's understanding model due to gap of the instructor's and child's knowledge. This fact implies it impacts the effectiveness of the education contents. The learning efficiency of Korean typography in WBI for children depends on the font-family, line space, font-size, the age of user, the output device such as the monitor, and other various factors. In this paper, we measured and analyzed on readability of Korean typography in WBI for children by reading speed method. The results of experiments show that readability depends on the font-family of typography, age(grade), and sex of children. In detail, "Goolymche" has the shortest time to be read, and girl and the highest grade students of elementary school have shorter time than boy and the lower grade students. Moreover, we consider the elegance of typography in WBI for holding children's interests because they prefer "Yopseoche". We provide some CSSs in WBI for children based on the experimental results, to used in school fields.

This study was conducted to examine differences in the relationship between experiential variables and outcome variables of experiential variables. In this regard, this research tries to construct the items based on past researches and to suggest the problems of the items of past researches. The analysis of various aspects of experiential variables and the validation tests of some models are presented to suggest what the optimal model is and the following suggestions can be made. First, respondents may not feel that the three dimensions of sensation, emotion, and cognition are significantly different. Depending on the respondents, there is a possibility that they may not be able to perceive much of the linguistic difference. The results of this study are summarized as follows. From this point of view, this study suggest that it would be suitable to proceed with the thesis with the experience of simplifying the combination of the five experiences in some combination. Second, there is a correlation between experiential variables, and the effect on outcome variables may vary from one variable to another. And, when there are two outcome variables, assuming a model that affects only the first outcome variable among the experience variables, it is the most suitable model in relation to the performance variable of experience.

Recently, the necessity of safety diagnosis of electrical devices has been increasing as the fire caused by electric devices has increased rapidly. This study is concerned with the safety diagnosis of electric equipment using intelligent Fuzzy technology. It is used as a diagnostic input for the multiple electrical safety factors such as the use current, cumulative use time, deterioration and arc characteristics inherent to the equipment. In order to extract these information in real time, a device composed of various sensor circuits, DSP signal processing, and communication circuit is implemented. The fuzzy logic algorithm using the Gaussian function for each information is designed and compiled to be implemented on a small DSP board. The fuzzy logic receives the four diagnostic information, deduces it by the fuzzy engine, and outputs the overall safety status of the device as a 100-step analog fuzzy value familiar to human sensibility. By experiments of a device that combines hardware and fuzzy algorithm implemented in this study, it is verified that it can be implemented in a small DSP board with human-friendly fuzzy value, diagnosing real-time safety conditions during operation of electric equipment. In the future, we expect to be able to study more intelligent diagnostic systems based on artificial intelligent with AI dedicated Micom.

In the capitalized Joseon Dynasty under the Japanese colonial rule, most Gisaengs (female entertainers) were waiting for men who would save them from financial distress, but others chose to seize the opportunity imposed by the modern times and capitalization to transform their lives. Socialist Jung Chil-sung was one of those who utilized such opportunity to transform themselves through political awakening. The political awakening of Chung Chil-sung was the result of two factors-the historical occasion of the March $1^{st}$ movement and her personal labor experience as Gisaeng. The March $1^{st}$ movement was not only a colossal political incident externally manifested in nationalism and but also an occasion which educed the microscopic anger of a woman named Chung Chil-sung. In the early capitalist society, women with jobs were forced to play not only vocational tasks but also to subject themselves to emotional roles of being obedient and generous. In other words, those early career women suffered feelings such as anger, shame and humiliation, when they were defenselessly exposed to gender hierarchy and gender power in the public sphere. As shown in the case of Chung Chil-sung, these emotions led to a certain political awakening. The political awakening through the labor experience and emotional problems was the fact that helped Chung Chil-sung have a concrete and realistic understanding about the issue of women's economic dependence unlike other female socialists. But, although socialism was relatively the most appropriate language to explain Chung Chil-sung's experience, what she experienced contained several elements that cannot be explained by the elite socialist language. Therefore, her life paradoxically proved the need of lower-class women's lives to be divided and registered as a new emotion and to be politically visualized.

This study examines the effects of job stress on fire-fighters' job performance on negative job factors, job burnout, and positive job factors, job satisfaction, respectively, and by examining whether resilience has a modulating effect in these influence relationships. This was done to provide useful information for planning management strategies. The analysis was done by regression analysis of data collected through a structured survey of 239 fire-fighters, and the moderating effect was confirmed by calculating and applying the interaction term. For the analysis, a structured questionnaire survey was conducted on 239 fire-fighters. As a result of the analysis, it was confirmed that job stress and job burnout of fire-fighters were low, job satisfaction was normal, and resilience was above average. Also, there was no significant difference in resilience according to demographic characteristics, and it was found that job stress had a positive(+) influence on job burnout at a statistically meaningful level, and a negative(-) influence on job satisfaction. In addition, it was found that impulse control power and cause analysis power had a moderating effect in the influence relationship between job stress and job burnout, and impulse control power had a moderating effect in the influence relationship between job stress and job satisfaction. Based on these results, it was proposed to preemptively apply various resilience programs suitable for the situation of fire-fighters, enhance emotional competence, and introduce coaching personnel to help self-reflection.
