The majority of table salts are bay salts and chemical salts. However, chemical salts are known to have a different composition in biological electrolytes and quality of bay salts are getting worse due to the increasing seawater contamination. These facts may have led to the increasing usage of various health-promoting salts. Bamboo salt was introduced in 1986 as a solution to replace table salts to eliminate those detrimental effects, to promote general health and to treat diseases. Although all bamboo salts from different manufacturers have been used for the same health and medical purposes, each manufacturer utilizes different manufacturing process. The ICP analysis was used to study the changes of elemental contents in a bamboo salt during the manufacturing steps as well as these contents in various bamboo salts and other salts. After the first step, contents of Li and Sr in the bamboo salt were increased in comparison with those in the raw material, bay salt. As the next steps continued, contents of K, Ca and Ba were continuously increased. At the completion of the final step, contents of Mg and P were decreased and those of Cu, Mn and Mo were gradually increased. Bamboo salts contained lower contents of Mg, Al, B, and P, but higher contents of K, Ca, Fe, Cu, Mn, Zn, Li, Ba, Sr and Mo than bay salt.

유화는 재료 상호간의 접착력과 온도 및 습도에 대한 서로 다른 반응으로 인해 매우 다양한 피해양상을 보이게 된다. 그중에서 유화에 있어서 지지대의 평면성 변형은 가장 중요한 피해양상이다. 지지대 변형을 조정하기 위해 사용되었던 열, 압력, 수분과 고전적인 재료의 무분별한 사용은 작품에 오히려 피해를 주는 원인이 되었다. 현대회화 복원에 있어서는 이들 위험요소를 가급적 피하는 방법들이 고안되었고, 실제작품들에 시행되어 만족할만한 효과를 거두고 있다 본고에서는 작업시 작품의 안전성을 꾀하고 복원효과의 극대화를 위해 사용되는 저압 테이블, 변형조정틀과 신소재를 이용한 새로운 지지대 변형 조정 방법을 소개하였다.

The importance of applying project management in interior design has been increased due to recent changes in construction business environment along with market opening which demands more systematized and organized project management system. Yet, project management has not been utilized for interior design industry in Korea. This study intends to define the concept of project management in interior design, categorize tasks of each phase in office design project, and establish a table of elements which should be considered in each task. The table can be utilized as a checklist at the designing site. An in-depth analysis was conducted on the tasks in the Designing phase. In short, this study demonstrates five management phases and nine tasks. The differentiated checklist for office design is discussed in the project management of the Design phase. The checklist established in this study can be used as a practical guideline not only for the clients who are not familiar with management of design project, but also for existing project managers and interior designers. Further studies on management of design projects and development of checklist other than office design is needed.

The purpose of this study was to explore the relationship between dietary behavior and the nutrient intake status in the youth of rural areas, based on their personal characters such as their sex, age, family type, number of family members, mother's age, occupation, and school career. This study was made by use of a self-administrated questionnaire with a 24-hour recall for 5days as an instrument with 439 randomly selected students. Statistical methods applied to analyze the data were frequency, percent, Willcoxon Rank-sum test, Kruskal-wallis test, x2-test by contingence table, and Spearman's correlation coefficient in non parametric statistical cases. Some of the interesting results are as follows : 1) The correlation between sex and breakfast is highly significant. That is, over 80% of male students had breakfast every day, whereas only about 60% of female students had breakfast every day. Bad table manners and some other problems are insignificant with respect to the personal characters in the relations between the personal characters and eating behaviors. However, the regularity of every meal, the frequency of having meals with other family members, and the frequency of meals eaten out and snacks show significant differences. 2) The mother's occupation does not have any influence on the nutrient intake of their students when the relationship between personal characters and nutrient intake was analysed. On the other hand sex, the mother's school career, the numbers of family members, the type of family, and the income of the family showed significant differences nutrient intakes. 3) The regularity and the frequency of having meals, meals eaten out with their family members, and the table manners during meals showed significant differences in the intake of nutrient elements such as calorie, protein, fat, fiber, calcium, iron, phosphorus, vitamin B1, vitamin B2, niacin and vitamin C. However some consideration during meals and problems in eating habit are insignificant with regard to nutrient intake.

The paper aims to study how to describe the rigorous position on which semantic elements are laid, within the visual space. This purpose is, first of all, for the construction of visual syntactical semantics of the visual space. For this aim, the preliminary research begins with some definitions on : 1) visual space, visual design, visual syntactical semantic meaning, 2) position, sequence of position, 2-dim. sequence of position, and 3) 2-dim. numerical series of position, harmonious dynamic values. Here, The main issue is to define the position in general. To solve this problem, the researcher surveyed the positions on which the sets of pixemes are set up. The results are as follows ; 1. As far as the positions in visual space are concerned, they are the possible locations permitted in the visual patches. They are not the factual but the possible positions. 2.The position value that the sequential point has is not arithmetical but harmonious-dynamic, for it is not permitted for its own sake, but for the person, that is to say, for the viewer's visual perception. 3. The harmonious-dynamic value of positional sequence can be composed of the 2-dimensional successive numerical series which is, in turn, composed of the primordial 3 values x0, $\mu0$, y0. Here, the $\mu0$ is the harmonious mean value of x0 and y0. The x0 and y0 are, therefore, of the mutual dynamic relationship. 4. From this, the 2-dim general $\Delta-TABLE$ of the numerical series of position in visual design could be acquired through development of the primordial 3 values into the $X_i,\;Y_i$, orbit values.

표는 자료 정리의 효과적 수단이지만, 그래프에 비해 시각적 한계가 뚜렷해서 수학교육분야에서 독립적인 연구주제로서의 위상을 차지하지는 못하고 있다. 그러나 표가 초등학교 수학과 교육과정에 명시적으로 포함된 만큼 표에 대한 체계적 연구와 합리적인 논의는 필요하다. 이 연구는 표를 다양한 용도로 적극적으로 활용하고 있는 핀란드 초등학교 수학교과서를 채택하여, 수학교과서에서 표가 어떤 의미로 어떻게 활용될 수 있는지 분석하였다. 연구결과 표는 통계영역 뿐만 아니라 수와 연산, 도형, 측정, 비와 비율 등의 수학내용을 전개하기 위한 유용한 수단이 될 수 있음을 확인하였다. 그 외에도 표의 외양이나 표를 구성하는 자료의 소재나 크기 등에 있어 의미 있는 시사점을 도출하였다.

Document page segmentation is an important step in building a quality optical character recognition module. The study examined already existing work on the topic of page segmentation and focused on the development of a segmentation model that has greater functional significance for application in an organization, as well as broad capabilities for managing the quality of the model. The main problems of document segmentation were highlighted, which include a complex background of intersecting objects. As classes for detection, not only classic text, table and figure were selected, but also additional types, such as signature, logo and table without borders (or with partially missing borders). This made it possible to pose a non-trivial task of detecting non-standard document elements. The authors compared existing neural network architectures for object detection based on published research data. The most suitable architecture was RetinaNet. To ensure the possibility of quality control of the model, a method based on neural network modeling using the RetinaNet architecture is proposed. During the study, several models were built, the quality of which was assessed on the test sample using the Mean average Precision metric. The best result among the constructed algorithms was shown by a model that includes four neural networks: the focus of the first neural network on detecting tables and tables without borders, the second - seals and signatures, the third - pictures and logos, and the fourth - text. As a result of the analysis, it was revealed that the approach based on four neural networks showed the best results in accordance with the objectives of the study on the test sample in the context of most classes of detection. The method proposed in the article can be used to recognize other objects. A promising direction in which the analysis can be continued is the segmentation of tables; the areas of the table that differ in function will act as classes: heading, cell with a name, cell with data, empty cell.
