In this study, we attempted to elucidate the cultural characteristics of Korean food based on a traditional understanding on the Korean novel. To achieve this, food characteristics related to 'rites of passage' were analyzed in the representative Korean literary work "Hon-bool", which describes the life of a first-son's wife every three generations in the going to ruin but historic 'Lee's family of Maean district' family and the life of the common 'Geomeong-gul' people who lived with farming on the Lee's land at Namwon of Junbook province in the 1930~1940s, during the Japanese Colonial rule. Every nation possesses rites of passage at important points in life, such as at birth, age of majority, wedding and death. Korean culture, in particular, has several memorial rites relating to birth, death and passage into the afterlife in which special foods are prepared. In this manner, ceremonial foods represent the Korean peoples' traditional vision of the universe and life. The book "Hon-bool" describes these traditions. Especially, the book describes the table-settings related to the main character's childbirth, first birthday, wedding and death. Therefore "Hon-bool" represents a living history of Korean traditional food and the work of storytelling through the traditional understanding is expected that perform an important role in making of cultural contents of Korean foods.

Earthwork is an operation that provides space for structures, and it takes up a large portion of the construction costs in a construction project. In large-scale earthwork, numerous types of construction equipment are used in the operation. The types of equipment should be selected based on the field conditions and the construction methods. These construction vehicles are constantly changing positions during the earthwork operation. Therefore, the equipment operators require effective communication to ensure the efficiency of the earthwork operation. All equipment operators should exchange information with the other equipment operators. Information should be exchanged continuously to support decision making and increase productivity during the earthwork operation at the construction site. This paper investigates the attributes required for an information interface between construction vehicles during an earthwork operation. This paper 1) discusses the importance of an information interface for construction vehicles in order to increase productivity during an earthwork operation, 2) analyses the types of attributes that need to be communicated between construction vehicles, and 3) provides a database that has been built for attribute control. The database built for the information interface between construction vehicles will enhance communication between vehicle operators. Table I shows the typical attributes that should be shared between the excavator operator and the dump truck operator. This information needs to be shared among the operators, as it helps them to plan the earthwork operation in a more efficient manner. A database has been developed to store this information in an entity relation diagram. A user-interface display environment is also developed to provide this information to the operators in the construction vehicles. The proposed interface can help exchange information effectively and facilitate a common understanding during the earthwork operation. For example, the vehicle operators will be aware of the planned volume, excavated volume, transportation time, and transportation numbers. As a part of this study, mobile devices, such as mobile phones and google glasses, will be used as hands-on communication tools.

Based on the multi-attribute utility theory (MAUT), we present a survey method to measure consumer preferences. The multi-attribute utility theory has been used to make decisions in OR/MS field; however, we show that the method can be effectively used to estimate the demand for new services by measuring individual level utility function. Because conjoint method has been widely used to measure consumer preferences for new products and services, we compare the pros and cons of two consumer preference survey methods. Further, we illustrate how swing weighing method can be effectively used to elicit customer preferences especially for new telecommunications services, Multi-attribute utility theory is a compositional approach for modeling customer preference, in which researchers calculate overall service utility by summing up the evaluation results for each attribute. On the contrary, conjoint method is a decompositional approach, which requires holistic evaluations for profiles. Partworth for each attribute is derived or estimated based on the evaluation, and finally consumer preferences for each profile are calculated. However, if the profiles are quite new and unfamiliar to the survey respondents, they will find it very difficult to accurately evaluate the profiles. We believe that the multi-attribute utility theory-based survey method is more appropriate than the conjoint method, because respondents only need to assess attribute level preferences and not holistic assessment. We chose swing weighting method among many weight assessment methods in multi-attribute utility theory, because it is designed to perform in a simple and fast manner. As illustrated in Clemen and Reilly (2001), to assess swing weights, the first step is to create the worst possible outcome as a benchmark by setting the worst level on each of the attributes. Then, each of the succeeding rows "swings" one of the attributes from worst to best. Upon constructing the swing table, respondents rank order the outcomes (rows). The next step is to rate the outcomes in which the rating for the benchmark is set to be 0 and the rating for the best outcome to be 100, and the ratings for other outcomes are determined in the ranges between 0 and 100. In calculating weight for each attribute, ratings are normalized by the total sum of all ratings. To demonstrate the applicability of the approach, we elicited and analyzed individual-level customer preference for new telecommunication services-WiBro and HSDPA. We began with a randomly selected 800 interviewees, and reduced them to 432 because other remaining ones were related to the people who did not show strong intention for subscription to new telecommunications services. For each combination of content and handset, number of responses which favored WiBro and HSDPA were counted, respectively. It was assumed that interviewee favors a specific service when expected utility is greater than that of competing service(s). Then, the market share of each service was calculated by normalizing the total number of responses which preferred each service. Holistic evaluation of new and unfamiliar service is a tough challenge for survey respondents. We have developed a simple and easy method to assess individual level preference by estimating weight of each attribute. Swing method was applied for this purpose. We believe that estimating individual level preference will be quite flexibly used to predict market performance of new services in many different business environments.

알고리즘을 지도하는 전통적인 방법은 우선 '표준 알고리즘'을 완성된 형태로 제시하고 이어서 간단한 사례를 통하여 이해한 다음, 보다 일반적인 문제에 적용함으로써 표준 알고리즘을 연습하는 형태이다. 그러나 이 방법은 표준 알고리즘에 지나치게 집중되어 있다는 문제점과 함께, 학생 스스로 문제에 적합한 알고리즘을 선택하거나 알고리즘 자체를 개발하는 경험을 제공하지 못한다는 제한점을 갖고 있다. 이 논문에서는 자연수 곱셈 알고리즘의 다양성을 활용하여 학생 스스로 알고리즘을 개발하고 발명할 수 있도록 지도하는 방안을 상세하게 구안하였고, 그에 따른 교수실험을 통하여 초등학교 3학년 학생의 곱셈 알고리즘에 대한 이해 과정을 분석하였다. 그 결과는 첫째, 실험적인 지도안으로 학습한 실험반은 자리값의 원리와 분배법칙의 이해에 있어서 비교반보다 높은 성취를 보였으나, 계산 능력에 있어서는 그렇지 못했다. 둘째, 비교반은 물론 실험반에서도 표준 알고리즘의 선호도가 가장 높았으며, 실험반에서는 표준 알고리즘 다음으로 격자곱셈의 선호도가 높은 것으로 나타났다. 격자 곱셈을 교육 소재로 활용하는 것을 적극 고려할 필요가 있다. 셋째, 비례표는 그것이 가지는 이론적인 장점에도 불구하고 우리나라 초등학교 3학년 학생이 배우기에는 다소 무리가 따르는 것으로 나타났다.

The purposes of this study were to survey the present situation of nutrition education in junior/senior high school, to analyze the difference between the favorite subjects on students and the existing subject done by dietitians on nutrition education, and then to identify the subjects of nutritional education for junior/senior high school students. Self-administered questionnaires were given to dietitians and students and 142 of the 200 dietitians (71.0%) and 479 of the 564 students (84.9%) responded to the questionnaire on the nutritional education. According to the survey results, 76.1 % of school dietitians currently were doing nutrition education for students while the other 23.9% didn't have such education programs even though they recognized the necessity strongly. The target of nutrition education was student rather than parents or teacher generally and the principal measuring method for nutrition education effect was change of plate waste and leftover'. It was found that significant difference in the collector and source of nutritional education information between junior and senior high school dietitians (p< .05) . About ninety-eight percentage of dietitians felt that nutrition education should keep pace with meal service and this meant that almost respondent recognized the necessity of nutrition education for students. Because the most serious one among operational problems of nutrition education program was lack of enough time owing to too many affairs as dietitian, junior and senior high schools should support so that dietitians would share enough time for nutrition education. And also, a gap was existed between actual and favorite subjects on nutrition education. Significant differences existed in the following subjects; 'basic concept of food and nutrition', 'disease and nutrition', 'food culture in the world', 'cooking and culinary art', 'food of the 24 divisions of the year in the lunar calendar', 'food waste and environmental issue', 'food habit and food behavior', 'exercise and nutrition' (p< .001) 'table manner', 'food and individual sanitation', 'recommended dietary allowance' (p < .01) and 'menu planning' (p< .05) .Finally, 24 subjects of nutritional education were selected based on the survey results. These subjects would be expected to be able to contribute the effective and interesting nutrition education program for junior and senior high school students.

매년 RDFS 데이터는 대용량화 되어 가며, 빠른 질의를 위한 SPARQL 처리방식에 대한 변화가 필요하게 되었다. 이를 위해 대용량 분산 처리 프레임워크를 활용한 SPARQL의 질의 처리방식이 많이 연구되고 있다. 기존의 연구 중 대용량 분산 처리 프레임워크인 Hadoop(MapReduce) 기반 질의 엔진은 반복적인 작업으로 인한 잦은 I/O 발생으로 실시간 질의 처리가 불가능하며, 인메모리 기반 분산 질의 엔진 역시 낮은 단계의 언어 수준에서 분산 구조를 고려한 구현이 필요하기 때문에 질의 엔진 구축이 어렵다. 본 논문에서는 인메모리 기반 분산 질의 처리 프레임워크인 SparkSQL을 활용하여 대용량 트리플 데이터에 대한 SPARQL 질의문 처리 속도를 향상시킬 수 있는 질의 처리 엔진 구축 방법을 제안한다. SparkSQL 은 Spark 기반의 고수준 분산 질의 엔진으로서 기존의 SQL문을 활용한 질의가 가능하다. 따라서 SPARQL 질의문을 처리하기 위해서는 Jena를 이용하여 Algebra Tree를 생성한 후 이를 Spark 시스템에 적용하기 위한 Spark Algebra Tree로 변환해야 한다. 그리고 이를 이용하여 SparkSQL 질의문을 생성하는 시스템을 구축하였다. 또한 Spark 인메모리 시스템에서 보다 효율적인 질의 처리를 위한 DataFrame기반의 트리플 Property 테이블 설계를 제안하고 SparkSQL 프레임워크에 활용하였다. 마지막으로 기존의 분산처리 프레임워크를 사용한 질의 엔진과 비교 평가를 통하여 연구의 타당성을 검증한다.

The purpose of this study was to investigate the elementary school dietitian's status and recognition of nutrition education (NE) in Incheon. A cross-sectional study was carried out using a self-administered questionnaire and subjects were 100 elementary school dietitians. The results are as follows. As for training in NE, $61.2\%$ of the dietitians attended training in NE. After training in NE, $86.5\%$ of the dietitians who attended training in NE were more concerned about NE. Also $59.5\%$ of the dietitians gave students NE and most of them did as a weekly printout 2-4 times per month. There was a significant difference in experience of NE for teachers between subgroups by experience of training in NE; while $48.1\%$ of the dietitians with training in NE gave teachers NE, $20.0\%$ of the dietitians without training in NE gave teachers NE. The main reason for not giving NE was too much work load and low concern of school administration. Also $96.4\%$ of the dietitians answered that NE is necessary in elementary school and the main reason for being necessary was correction of unbalanced diet and good table manner, As for proper time to start NE for children, $51.8\%$ of dietitians answered 'kindergarten' and $45.8\%$ of them answered 'lower grade of elementary school'. As for effective type for NE, $59.5\%$ of the dietitians answered 'NE as a part of other subject' and $23.8\%$ of them answered 'NE as a separate subject'. Also $79.5\%$ of the dietitians answered 'teacher' as the suitable person for NE. Most of the dietitians recognized menu formation as the ideal major work load and office work as the most time-consuming work load. As to job satisfaction, most of them were dissatisfied with office work and NE. Therefore, it is nationally supported for elementary school students' health and well-being that school dietitians as NE specialists give NE with minimizing their office work and developing a standardized NE program.
