It is thought as more important for us to understand foreign countrie's culture in the modern society. because the world is becoming closer day by day thiough the develepment of communication and mass-media. Cross-cultural study could play a role to give an opportunity for people to understand foreign countrie’s culture easily.In this respect, this study was planned to find out similarity and difference between Danish and Korean folk tables made and used before the 20th century during the 18th-l9th century as a part of the comparative study of folk furniture between the two countries. It would be very interesting if we could find something valuable between Danish and Korean folk furniture. because they are located very far away each other geographically with less cultural communication before.There were more differences than similarity between the folk tables of the two countries and major findings were as followings : Firstly, there were many kinds of space-saving tables in Denmark. whereas only a few kinds of tables which could be removed easily after their usage were found in KoreaSecondly, Banish folk tables were more emphasized on the function rather than decoration. Whereas Korean folk tables were smaller lower and more decorative than Danish ones to fit their life-style of sitting on the floor.Thirdly, many Danish folk tables were made of bare wood. while Korean ones were finished by transparent lacquer or vegetable oil. Stone tops if tables were rare in both countries. Lastly. there were common factors in the design of legs of folk tables in both countries. It was interesting that animal legs such as deg tiger cat. lion, and eagle were used for design motif of the table legs. But trestle leg, cross leg and gate leg were not found in Korean folk tables. As a conclusion, throughout this study, it became obvious that life-style was one of the most important factor influencing on the design of furniture.

In the Web, the data is generally gathered automatically by Web servers and collected in server or access logs. However, as users access larger and larger amounts of data, query response times to extract information inevitably get slower. A method to resolve this issue is the use of summary tables. In this short note, we design a prototype of summary tables that can efficiently extract information from Web log data. We also present the relative performance of the summary tables against a sampling technique and a method that uses raw data.

Keys play a fundamental role in all data models. They allow database systems to uniquely identify data items, and therefore, promote efficient data processing in many applications. Due to this, support is required to discover keys. These include keys that are semantically meaningful for the application domain, or are satisfied by a given database. We study the discovery of keys from SQL tables. We investigate the structural and computational properties of Armstrong tables for sets of SQL keys. Inspections of Armstrong tables enable data engineers to consolidate their understanding of semantically meaningful keys, and to communicate this understanding to other stake-holders. The stake-holders may want to make changes to the tables or provide entirely different tables to communicate their views to the data engineers. For such a purpose, we propose data mining algorithms that discover keys from a given SQL table. We combine the key mining algorithms with Armstrong table computations to generate informative Armstrong tables, that is, key-preserving semantic samples of existing SQL tables. Finally, we define formal measures to assess the distance between sets of SQL keys. The measures can be applied to validate the usefulness of Armstrong tables, and to automate the marking and feedback of non-multiple choice questions in database courses.

To examine the next following day party and the next following evening party in the Man Kyong Geon, the authors analyzed“Jin Chan Eui Gue”, which is a historical record, published in 1887(King Go-Jong). The results obtained from the study were as follows, 1. The dining tables of next following day party were composed of two types:fixed arranging tables(22), and taking-away tables. 2. The dinind tables of next following evening party were also composed of two types:fixed arranging tables(6), and taking-away tables. 3. Food and flowers were distributed to the 290 attendants at the next following evening party. 5. According to the status or class of the attendants, the pattern or size of table settings were differentiated in the kinds of food, heights of food, flowers china ware etc. 6. Arrangements of the next following day party and the next following evening party were the same as those of the main party. 7. The arranged seat of the Crown Prince was facing the west. 8. In the arrangements of tables for the Crown Prince, the heights of food on dishes as following levels, 1 dish : 1chok(1척) 6 dishes : 8 chon(8촌) 5 dishes : 7 chon(촌)

Very accurate calibration is needed to index tables which are necessary for precision angle measurement. The repeatability of index table is less than 0.2 second, so that attentions should be paid to choosing devices to be used in the calibration of index tables. The auto- collimators have been used in the calibration of index tables, but the repeatability of auto- collimators is bad compared with that of index table. In place of autocollimators, we described a method which uses electric comparators which are possessed by most precision measurement laboratories. Electric comparators are set to measure small angle displacement without interrupting the rotation of index tables and the signals of two electric comparators are added to remove the run-out errors of the shafts of index tables. Two index tables have been calibrated simulataneously by this method and the measurement data have been analyzed by the least squares method. We compare the calibration results with those of methods using autocollimator and auto- matic autocollimator and are able to know that the data of electric comparator method lie between the data of autocollimator methods. The repeatability of measurement is less than 0.02 second. The electric comparator method is economical and capable of reducing the uncertainty of the measurement.

본 연구에서는 조기표를 활용하여 차세대 도서관 목록(NGC)에서 강조하는 검색 결과의 패싯 내비게이션 기능을 개선하고자 하였다. 조기표는 자료의 형식적인 측면이나 내용 측면을 체계적으로 나타내므로, 기존의 NGC에서 제공하고 있는 주요 패싯인 언어나 발행년도, 주제(대구분)와 같이 효과적인 패싯이 될 수 있다. 이에 한국십진분류법(KDC)을 적용한 서지레코드의 분류기호를 분석하여, 본표와 조기표의 합성 현황과 특징을 도출하였다. 그리고 이를 바탕으로 본표에 합성된 조기성 기호가 패싯 내비게이션 기능 강화에 활용될 수 있음을 제안하였다. 이 방안은 분류기호를 부여하기 위해 기존에 이루어져 왔던 주제 분석 과정의 산물을 재사용할 수 있다는 추가적인 이점도 가지고 있다.

The purpose of this study was to evaluate the effect of implementing the HACCP system on foodservice establishments. At first, the hygienic conditions were measured by microbiological hazard analyses of the cooking utensils and working areas. In order to solve the detected problems, the HACCP system was implemented, after what was considered a sufficient settlement period following the initial assessment, then microbiological verification was performed again. In relation to the cooking utensils and equipment(kitchen knives, cutting boards, knives for shredding vegetables, refrigerators, baskets, barts, working tables, preparation tables, tungs, dish-clothes and drains) the microbiological inspection on the Total Plate Count, Coliforms, Staphylococcus aureus and Listeria monocytogenes, were conducted with regard to the working areas(working tables, preparation tables, seasoning's shelves, serving tables, drinking water tables, refrigerators, storage rooms and dining tables), the Total Plate Count and Fungi were also examined. According to the microbiological hazard analyses there were many problems, especially with cutting boards, baskets, barts, dish-clothes and sinkballs. However, by introducing the HACCP system, the microbiological hazard levels were able to be controlled and lowered, and the total aerial bacteria in the working areas of the foodservice establishments were detected at levels below 6 CFU/plate.

생명표란 어떤 출생집단이 나이가 많아짐에 따라 연령별로 몇세까지 살 수 있는가를 계산하여 정리한 표이다. 생명표는 주로 인구학 분야에서 연령별 사망율 예측에 주로 이용되어왔다. 그러나 본 연구에서는 생명표가 다양한 분야에서 사용되는 점을 착안하여 생명표 활용 영역을 정리하고 분류하고자 하였다. 2011년 이전에 국내외에서 발표된 대부분의 논문을 조사하여 생명표 분류에 이용하였다. 본 연구에서 분류기준은 다음과 같다. 첫째, 응용여부에 따라 일반생명표와 응용생명표로 나누었다. 둘째, 기준기간에 따라 5세를 작성단위로 하는 간이생명표와 1세를 작성단위로 하는 완전생명표로 나누었다. 셋째, 성별에 따라 남성생명표, 여성생명표, 남녀혼합생명표로 나누었다. 관찰 방법에 따라 기간생명표와 코호트 생명표로 나누었다. 마지막으로 이와 같이 분류된 생명표의 작성방법을 비교 분석해 봄으로써 더 다양한 분야에 생명표가 활용될 것을 제안하고자 하였다.
