The purpose of this study was to identify critical control points of service encounter by types of restaurants in order to manage moment of truth when customers encounter services. Questionnaires were collected from 812 customers (aged 15 years or older) who had used restaurants in Seoul, from October 24, 2005 to November 6, 2005. The main results of this study were as follows: Statistically significant differences were shown between importance and performance of interaction quality, physical environment quality and outcome quality. Significant differences were also shown in importance and performance of interaction and physical environment quality, and performance of outcome quality by restaurant types but no significant difference was indicated in importance of outcome quality by restaurant types. That is, the importance of outcome quality, which means the quality of food, was regarded as important by customers who use restaurants regardless of types of restaurants. The result of examining interaction quality showed that family restaurants managed waiting customers quite well and provided information on the Internet homepage. Performance of responding to customers with complaints was rated the highest in family restaurants. Regarding physical environment quality, importance and performance scores significantly differed by types of restaurants in order of fine-dining restaurants, family restaurants, and fast-food restaurants. In terms of service encounter quality, items whose importance scores were high but performance scores were low in importance-performance analysis matrix were 'quality of provided food is always uniform' and 'the space between other tables is enough' for fine-dining restaurants. In family restaurants, 'size of chairs or tables is enough', and 'the space between other tables is enough' were included in the items, while 'interior facilities are attractive', 'size of chairs and tables is enough', and 'the space between other tables is enough' were included in the items in case of fast-food restaurants. A difference was indicated depending on types of restaurants.

This study was carried out to establish an effective marketing strategy based on Importance-Performance Analysis (IPA) of rice-convenience foods. IPA is one of the most efficient and simple methods to evaluate product quality. Data were collected from 652 people (320 males and 332 females) and analyzed by SPSS 19.0. Subjects consumed rice-convenience foods as a snack substitute (19.3%), breakfast (20.7%), lunch (37.4%), dinner (15.2%), and late-night meal (7.4%). The purpose for consumption of rice-convenience foods were as follows: light meal (34.8%), lack of time to prepare meal (42.2%), favorite restaurant is not nearby (2.3%), save money (3.4%), and outdoor activities (9.7%). All attributes about rice-convenience foods were categorized into intrinsic property and extrinsic property. As a result of factor analysis, health, sensibility, and diversity factors were extracted from intrinsic property. In addition, dependence and appearance factors were drawn from extrinsic property. In analyzing the differences between importance and performance, there were significant differences; 16 items in the intrinsic property (P<0.01), and 10 items in the extrinsic property (P<0.001). The IPA matrix is composed of four quadrants, and each represents different strategies; the first, 'keep up the good work', the second, 'possible overkill', the third, 'low priority for management', and the fourth, 'concentrate management'. As a result, factors of rice-convenience foods positioned in the fourth quadrant were 'safety (from food additives, etc.)' and 'price' in the intrinsic property and 'nutrition label' and 'safety of packaging material' in the extrinsic property. They need to be improved immediately. In this study, rice-convenience food factors for continuous maintenance and concentrative improvement were compared by IPA. Based upon the results of this study, it is necessary to develop methods to make efficient use of limited resources and practical marketing strategies.

The purpose of this study was to extract the evaluation factors and assess the relative importance between the factors. For this purpose, the evaluation factors were extracted through literature review and the process of brainstorming with experts, who are related to port security. The evaluation factors were then classified into four higher factors and twelve sub- factors through the use of the AHP method. A survey on the classified factors was conducted by experts composed of public officials, port authority employees and education institutions officials. We also carried out statistical tests to determine the perception gap of weights between the groups. As a result of a relative importance analysis of strength, the security operating system factor was highest, followed by improvement of hardware facilities and increase of security personnel. There was a difference in perception among the groups in policy support, facility support and personnel resources budget support. The results of the analysis show that the strength operating system through the establishment of an integrated monitoring system is a priority. It is necessary to understand the difference of perception between groups and build a systematic cooperation system. The evaluation factors extracted from this study can be used for the measurement of port security efficiency in further work.

지역 빈도 분석과 점 빈도 분석은 하천 기본계획 및 수공 구조물의 설계에 있어 재현기간 별 확률강우량을 산정하기 위한 방법이다. 점 빈도 분석은 자료의 수가 부족하여 높은 재현기간에 대한 확률강우량을 산정하기에 어려운 점이 있다. 2019년도부터 사용되고 있는 지역빈도분석 방법은 이러한 점을 보완해주고 있다. 지역빈도분석을 수행하기 위해서는 지역의 동질성을 확인하는 과정이 가장 중요한 과정이다. 이러한 동질성을 판단하기 위하여 K-means등의 군집분석과 L-moment 법 등을 사용하고 있다. 이러한 차이점으로 인해 두 방법 간의 정확성은 비교가 어려우나 서로 간의 장점, 단점과 결과 간의 차이를 기반으로 산간지역이 많은 강원도와 같은 지역에 대한 확률강우량 산정의 적절한 방법을 판단해보고자 본 연구를 진행하였다. 지역 빈도 분석은 강원도에 위치한 48개 관측소의 강우 자료 수집 후 고도, 위치, 지속시간 별 강우량을 변수로 지정하고 K-means 분석을 통해 6개의 군집으로 구분하여 수행되었다. 이질성 척도는 관측 자료와 500번의 모의 수행을 통해 결정하였다. 이후 분석된 군집이 동질한 경우 확률분포형에 적합시켜 확률강우량을 산정하였다. 점 빈도 분석은 지역 빈도 분석에서 결정된 군집에서의 최대 강우량과 최소 강우량 관측소의 자료를 이용하여 수행하였다. 본 연구에서는 점빈도분석과 지역빈도분석의 결과를 비교하였으며, 두 가지 분석 방법에 따른 차이의 발생원인 및 특성을 결론으로 제시하였다.

컴퓨터의 빠른 발달과 보급 속도로 인해 사용자와 컴퓨터 간의 상호작용(Human-Computer Interaction; HCI)이 중요해 지면서, 인터페이스 개발과 평가가 강조되고 있다. 본 논문에서는 컴퓨터 시스템의 정량적 사용성 평가에 널리 이용되는 GOMS에 대한 이해와 함께 인터페이스 평가에서의 GOMS의 한계와 개선 방향에 대하여 알아보고자 한다. 먼저 연구 대상이 되는 컴퓨터 작업 환경을 선정하고, 특정 작업에 대한 작업 분석을 실시하였다. 그리고 작업 분석 결과를 바탕으로 NGOMSL을 이용하여 모델링 하였다. 모델링 결과 작업 Operators의 구성을 알 수 있었고, 총 수행시간과 학습시간을 예측할 수 있었다. GOMS 모델링 결과가 실제 사람의 수행 결과와 얼마나 일치하는지를 비교하기 위하여 Empirical Test를 실시하였고, 그 결과 GOMS 모델링을 통해 예측된 수행시간과 실험을 통해 얻은 총 수행시간 사이에는 큰 차이가 있음을 알 수 있었다. 이러한 차이를 줄이고 실제 사용자의 수행과정과 유사하게 모델링을 하기 위하여 두 가지 가정을 바탕으로 GOMS 모델을 개선하였다. 본 연구를 통하여 GOMS 모델링은 컴퓨터 시스템의 효과적인 상대적 사용성 평가 도구로 활용될 수 있음을 확인할 수 있었다.

Purpose: This study was to evaluate students and optometrist in the importance and difficulty of work capability, and the educational needs for optometric duty in order to use them as basic data for the improvement of the curriculum. Methods: 292 ophthalmic optic's college students and 123 optometrists were surveyed in the importance and difficulty of work capability, and the educational needs for the optometric duty, and data was statistically analyzed for the results. Results: The mean of the importance of work capability was higher for the optometrists (3.61) than for the students (3.51) and glasses dispensing was the highest for both students and optometrists. The mean of the difficulty of work capability was higher for the students (2.75) than for the optometrists (2.67), which was the highest in refraction for the students and in prescription for the optometrists. The mean of educational needs was higher for the optometrists (3.53) than for the students (3.45), which was the highest in glasses dispensing for the students and highest in refraction for the optometrists. There were significant differences in some tasks in between the students by gender, grade and desired working place, while between the optometrists by gender, age, work experience, working place and working area (p<0.05). Conclusions: It is necessary to improve a curriculum of the Department of Opthalmic Optics, and develop a standard curriculum reflected the importance and the difficulty of work capability, and the educational needs regarding to optometric duty.
