The objective of this study was to suggest a new efficiency measurement indicator for evaluating the menu management efficiency of decision making units(DMUs) in contract-foodservice operations and to determine the relationship between the DEA(data envelopment analysis) menu efficiency score and menu factors. The results of applying DEA revealed relatively efficient types of service and frequency of meals. The efficient service was shown as a self-service type that operates Monday to Saturday. The considered menu factors included meal price, food cost per meal, meal counts, number of menu items, use of favorite menu use, forecasting error, accuracy of ordering, ratio of inventory, ratio of food loss, use of processed foods and use of prepared vegetables are considered. There were significant correlations between the DEA score and meal price, meal counts, number of menu items, ratio of food loss, accuracy of ordering and use of processed foods respectively. According to the regression results, menu price had a positive influence on the DEA menu efficiency score, and food cost per meal and the use of prepared foods had negative influences respectively.

The effect of menu width and depth on the efficiency of information search and menu preference was investigated to identify an optimal menu structure for EIG which reflects the characteristics of human information processing. Information search time increased stepwisely as the menu width exceeded 6 items and linearly as the level of menu depth increased. The linear relationship between the error rate and the number of depth levels seems to be caused by the increase in the items to be remembered. When a menu structure was constructed by combining different menu depths and widths, it was observed that making the menu width wider rather than the depth deeper allows better information search. The menu structure rated as the most preferable and the easiest to user was that of pyramidal form. Such a result seems to come from its structural similarity to general categories which people get used to and implies that one should consider user preference as well as efficiency of search when he/she designs an EIG menu.

This study aimed to develop Chinese restaurant set menu which was proper to tendency of market segmentation by using conjoint analysis. In order to examine tendency of market segmentation, this study investigated the important factors and effective values of whole market and segment market. First, the study found that whole market and segment market seemed to prefer seafood to meat except Cluster 3 (Gentle demand type). Second, regarding efficiency of attribute level, the study found that crap soup is favored over seafood in both whole market and segment market except Cluster 1 (strong demand type). Third, Cluster 1 (strong demand type) showed a high level of efficiency on menu which is mixed with meat and seafood. In Cluster 2 (middle demand type), there was a high level of efficiency in meat menu. In case of Cluster 3 (gentle demand type), seafood menu showed high level of efficiency. Forth, there was a high level of efficacy in rice and western dessert menu on the result of analysis on whole market and segment market. Therefore, this study suggests that the preference of seafood is more higher than the preference of meat. It means that current customers care their health more than they used to be. According to this study, people who want to develop Chinese restaurant menu should focus on seafood more than meat. What's more, marketers of chinese restaurants have to not only present new awareness and fresh atmosphere but also provide typical composition of set menu for target customers.

컴퓨터 시스템에서 화면상의 복수의 항목 중에서 특정 항목을 선택하고 실행하기 위해 가장 널리 사용되는 도구가 메뉴인데 정보량이 급격하게 증가하면서 동적 메뉴와 같은 새로운 메뉴가 많이 개발되고 있다. 본 연구에서는 실험을 통해 풀다운(pull-down) 메뉴, 피시아이(fisheye) 메뉴, 그리드(grid) 메뉴의 객관적 수행도(수행시간, 오류)와 사용자의 주관적 평가(단순성, 사용 효율성, 친근성, 전반적 선호도)를 비교분석 하였다. 중간 수준의 메뉴 항목이나 작은 화면을 고려하여 개발된 그리드 메뉴는 메뉴 항목의 수가 중간 수준(50개)이나 많은 수준(100개)일 때, 풀다운 메뉴와 피시아이메뉴보다 수행시간에 있어 효율적인 것으로 나타났다. 메뉴항목의 수와 수행시간 사이에는 모든 메뉴가 비례관계를 보였으나 그리드 메뉴가 가장 둔감하게 반응하였다. 풀다운 메뉴와 그리드 메뉴는 피시아이 메뉴에 비해 보다 간단하고, 친근하고, 효율적인 것으로 평가되었으며 42.3 퍼센트의 피험자가 그리드 메뉴가 메뉴들 중에서 가장 우수하다고 평가하였다. 결론적으로 그리드 메뉴는 메뉴 항목의 수가 적거나 중간 정도의 수준일 때 효율적인 디자인 대안으로 선정될 수 있을 것으로 판단되며 모바일 기기에서의 효율성을 살펴보기 위해선 보다 심도 깊은 연구가 요구된다.

This study reviews several database menu structure for pc communication services to examine the efficiency of database menu structure. Database menu systems of 5 major pc communication companies were analyzed by GOMS methodology, a description of the knowledge that a user must have in order to carry out tasks on system. Also, each database access time of 4 pc communication companies were measured with internet pc environment in laboratory. It is recommened that another menu design strategies (for example, broad-shallow rather than narrow-deep) should be adopted because current menu structures have inefficient procedures to access those database.

Objective: We proposed an effective 3D menu manipulation alternative with a usability test. This was performed in a 3D environment with 3D menu and control manipulation methods. Background: As 3D stereoscopic displays became generalized, various 3D applications were being used not just movies, games, but also mobile contents and advertisements. However, when a user interface was designed in a 3D environment, it was lacked that a clear standard and result of an efficiency and usability as like a 2D environment. Method: We implemented 9 kinds of 3D menu types based on 3D menu hierarchies, menu layouts and dimensions. And we extracted 3 representative control types in a 3D environment. We performed usability evaluation with full factorial design for 27 menu alternatives with 2 types of menu manipulation tasks. In this condition, we measured the performance time, subjective discomfort and eye-fatigue. Results: A control type had the significant effect, and the effect of menu types had the different result depending on given tasks. Conclusion: This experiment showed the interaction of menu and control types depended on 3D menu manipulation tasks were significant in a 3D user interface design. Therefore, as a purpose of a 3D menu manipulation task, 3D menu types and control types were should be considered. Application: We supposed this result was should be applied in a 3D menu contents design.

This study aims at efficiency of kitchen management by adoption of a systematic central kitchen and conversion of conventional kitchen to convenience kitchen at ' H ' restaurant. First, integrated menu control of banquet buffet functions became more competitive with quality menu and eventually brought about guests satisfaction. Second, systematic central kitchen made possible standardization and mass production through simplified production line. Efficiency through quick service and shortened preparation time was realized, and food materials were recycled effectively at the same time. Integrated ordering lowered purchasing price and built an efficient cost control system. Third, conversion of conventional kitchen to convenience kitchen and strengthened central kitchen system facilitated agreeable work conditions and optimal work flow with butcher's and even sauce making utensils. Fourth, integrated supply system of buffet menu and sauce from western restaurants saved about 520 million won of labor costs. Last, one integrated kitchen out of two was easier in sanitation control with pleasant restaurant space. Sharing kitchen facilities and equipments also saved about 30% of maintenance fee. Power, water, and gas were also saved and eventually curtailed overall expenses.

The present study employed an experimental usability testing technique to explore cognitive engineering characteristics of WWW. Based on the results of our previous study which employed non-experimental methods such as questionnaire and heuristic evaluation method, this study used a behavioral performance-measurement technique to evaluate the usability of a domestic web-site design. Specifically, we revised the menu and document structure of the original 'Movie-Friend' site to solve the design problems which were extracted from the results of the heuristic evaluation method of our previous study. Exp. 1 compared the relative navigation efficiency of the original frame menu site and the revised pop-up toolbar site, and Exp. 2 compared the toolbar menu site and the revised frame site. As a result of Exp. 1, the revised pop-up toolbar site showed improved navigation efficiency compared to the original site, as indicated by the mean latency and the number of pathways to reach the target page. However, we found no performance difference between the frame site and toolbar site in Exp. 2.
