This study aims to content analysis of Library Classification System in the North Korean. Also This paper is analyze and overview to conceptual framework. Notational system. Principle of hierarchy in the North Korean's Library Classification System. Libraries usually arrange their collections according to the systematic structure of the library classification. A decimal point follows the third digit. After which division by ten continues to the specific degree of classification needed. This system is based on the social and communism thought. The libraries in the South and the North has different concepts, goals, information resources, classification system and the different ways of using them. Considering the practical aspects of the libraries and the reasons for their existence, they must structure the mutual cooperative system so as to minimize the shock when confronting the social changes, so-cold the national unification.

This study focuses on establishing a base for approaching record disposition schedules, which may be felt unfamiliar, through the overview of record disposition schedules. For this purpose, this study examined the meaning of record disposition schedules, the significance and principle of their elements, and their operation. In addition, it presented tasks to perform for record disposition schedules to play a central role of record management in the future. This study showed that record disposition schedules authorize people to control and process records, and are closely related to the development and the stability of record disposition system in Korea. What is more, it proved that record disposition schedules enable the assessment of the historical values of records, so it is possible to maintain records from the perspective of historical records. Besides, record disposition schedules are important in that they contain information on organizations and their functions, based on which we can preserve and manage extrinsic information about records.

교통계획의 수립은 사람과 화물의 이동상태에 대한 파악으로부터 시작되며 화물이동상태를 파악 하기 위한 가장 기본적인 데이터는 지역별 발생집중 화물량일 것이다. 이러한 지역별 발생집중 화물량의 추계방법중 추계의 간편성과 경제상황변화의 반영이 용이하다는 점에서, 최근 학자들의 상당한 주목 을 받으며 연구되고 있는 것이 산업연관분석을 응용한 물류해석방법이다. 그러나 이방법은 대상지역의 산업연관표를 기본 data로 하기 때문에 해당지역의 산업연관표의 존재 여부에 따라서 그 적용범위가 제한된다. 이러한 문제점을 해결하기 위해서 연구되고 있는 방법이 Nonsurvey법이다. Nonsurvey법은 대 지역의 산업연관표로부터 그 지역에 포함된 소지역의 산업연관표를 여러 가지 보조적인 데이터를 이용해 서 간접적으로 추계하는 방법이다. 본연구에서는 이러한 Nonsurvey법의 하나로서 대지역의 산업연관표 와 지역분해된 각 소지역의 산업부문별 생산량만을 이용해서 각 소지역의 발생집중화물량을 추계하는 방법을 제안했다. 그리고 일본의 긴키(Kinki)지역과 이에 속하는 4부현을 대상으로 본연구의 방법으로 추계된 이출입양과 실제의 산업연관표상의 이출입량을 비교.분석함으로써 본 연구의 방법에 대한 검증을 실시했다. 본 연구에서 제아한 지역별 발생집중 화물량 추계방법의 특징은 다음과 같다. 첫째, 대지역내 각 소지역간의 이출입량이 분기계수라고 하는 산업관계표의 산업관계표의 행방향의 합에 대한 비율을 사용함으로서 간단히 추계가능 하다. 둘째, 추계된 소지역의 산업관계표는 대지역에 대한 시스템전체의 정합성이 유지된다. 셋째 분해되는 소지역의 수에 관계없이 각소지역의 이출입양에 대한 추계가 가능하다.

We have studied on equivalent length tables which are used to calculate the friction loss of pipe fittings and valves of water-based fire systems in Korea. Three kinds of equivalent length tables are mainly used and unfortunately, the most extensively used table is not ascertained the reliable source. When the three tables are compared, each table has different equivalent length up to 2.4 times in same item. We should use unified equivalent length table which is scientifically reasonable in order to act up to globalization as performing lots of over-sea projects. Therefore, we propose the reasonable equivalent length tables.

우리나라 수위관측소에 설치되어 있는 수위표는 야간 시인성 부족으로 야간이나 우천시 수위관측을 수행하는데 있어 많은 어려움이 있다. 특히 유량측정 전후 수위관측이 반드시 필요하지만 야간일 경우 눈으로 확인하는 것이 쉽지 않다. 야간 수위관측시 시인성을 높이기 위해 일부 관측소에서 야광도료를 이용하거나 빛의 반사효과를 높인 수위표를 설치하는 등의 노력을 하고 있으나 그 효과는 크지 않다. 이에 본 연구에서는 야간 수위관측시 수위 식별이 어려운 문제를 해결하기 위해 첨단 소자인 LED(Light Emitting Diode)를 이용한 수위표를 개발하고 동시에 전류식 수위센서를 이용하여 자동 수위측정이 가능한 수위표를 개발하였다. 이는 기존의 눈으로 확인하는 수위표와 로거에 저장되는 수위측정장치를 하나로 통합한 것이며 주야간을 가리지 않는 탁월한 시인성과 정확한 수위측정 및 수위자료의 저장이 특징이다. LED는 최근 각광받고 있는 첨단 소자로서 각종 전광판 등에 다양하게 활용되고 있으며 전력을 크게 소비하지 않는 것이 특징이다. 또한 전기장치를 수중에 설치하는 것이므로 방수를 위해 실리콘을 이용하여 완벽 방수구조를 갖추었으며 홍수시 하천 유하물에 의한 파손을 방지하기 위해 내구성을 갖춘 구조로 설계 제작하였다. LED를 이용한 수위표는 야간이나 홍수시 수위관측을 수행할 때 많은 장점이 있을 것으로 판단되며 저전력 구조로 상용전원을 이용할 수 없는 위치에서 태양열 전지판을 이용한 배터리 기반 시스템으로 구성할 수 있으므로 측정의 정확도, 활용도 측면뿐만 아니라 설치의 편리성 문제도 큰 장점을 가질 것으로 판단된다.

Two-way specification table for educational objectives proposed by B.S.Bloom, which is useful in reviewing and determining the objectives of instructions, is widely used in schools. However, differences in subject matters and school environments require various types of two-way specification table. Extensible markup language (XML) can be effectively applied for two-way specification table for educational objectives because it is well structured and the content of an XML document can be separated from its presentation. In this paper, the document type definition (DTD) for two-way specification table was designed. An example of XML document and XSL style sheet for the table were also presented. Furthermore, applications of the designed DTD were discussed. It is expected that the proposed DTD can be useful to various applications related to education assesment.

Field experiments were carried out to improve the cultural practice of potato by analysing its tuberization patterns. Tuberization patterns affected by different altitudes was analyzed at two potato cultivation regions, Jinbu (600 m) and Daegwallyung (800 m) using two potato cultivars, 'Superior' and 'Atlantic'. To analyse tuberization patterns affected by different planting time, seed potatoes were planted at every 10 days from April 19 to May 19 in Daegwallyung. Total dry weight was greater in plant grown at the altitude of 800 m than 600 m during the entire growth period and the highest increase was observed at the early growth period, July 6, comparing to other growth period. The total dry weight was the greatest at 110~112 days after planting (DAP) at the altitude of 800 m and 108~111 DAP at 600 m. There was no significant differences between altitudes and between cultivars. Tuber dry weight per plant at the altitude of 600 m was lower than 800 m on July 6 (58 DAP), but it increased rapidly from July 21 (73 DAP). At both altitudes, the increase of tuber dry weight per plant from July 6 to August 8 was higher than the other growth period. The time of growth period at which tuber dry weight per plant was the highest was similar at both altitudes that was 118~125 DAP at the altitude 800 m and 118~124 DAP at the altitude 600 m. Dry weight per tuber at the altitude 800m was higher than 600 m due to the number of tubers per plant. A higher increase of crop growth rate (CGR) was shown at the altitude 600 m on July 6 (58 DAP), comparing to at 800 m. The highest tuber dry weight per plant of each cultivar was shown when the planting time was April 29 for 'Superior' and was April 19 for 'Atlantic'. Both the tuber dry weight of plant and the total dry weight were lower at a later planting time. Dry weight per tuber increased quickly during the period between June 30 to August 8. Tuberization period was shortened as the planting time was delayed.

Thirty-five elementary schools in Gwangju and Jeollanam-do were surveyed on the installation status of plant labels. As a result of a comprehensive evaluation of the installation and condition of the plant labels, 12 out of 35 elementary schools were evaluated as "excellent," 13 as "good," and 8 as "insufficient." In some cases, various types of plant labels were installed on various types of plants and were updated continuously, indicating that the school members recognize the plant labels as an important educational tool. Meanwhile, some schools did not have a single plant label. Although plant labels were installed, instances occurred where they were neglected without continuous maintenance and management. Some plant labels were produced and installed by specialized companies, leading to errors in content or inadequate post-installation management, thereby compromising the school landscape. Therefore, we propose an alternative-allowing schools to independently produce and install plant labels. This approach preserves the school's uniqueness, and the process of producing and installing sustainable plant labels becomes an active educational tool.
