현재의 농어촌은 고령화로 인한 인력 및 장비부족, 농산물 가격하락 등 여러 환경이 갈수록 열악해지고 있는 실정이다. 본 연구는 이러한 문제를 해결하기 위하여 수 많은 농업기반시설물 중 중요 관리대상인 관정, 양수장, 취입보 등을 대상으로 데이터베이스 구축하여 점검, 고장 및 수리 등의 이력사항을 관리하기 위하여 수행되었다. 특히, 관정의 경우에는 무분별한 설치와 공간정보 부재로 인하여 경제적 손실 및 환경오염 등의 문제를 야기시키기 때문에 수문지질도, 수맥도, 지하수 심도 등의 공간정보를 이용하여 관정의 최적위치를 결정하였다. 따라서, 본 연구는 시스템 개발을 통하여 농촌지역에 산재되어 있는 수 많은 시설물들을 효율적으로 관리할 수 있었고, 공간정보를 이용하여 14개 관정에 대한 현황을 분석한 결과 6개 지점에서의 위치정보가 잘못된 것으로 나타났으나, 현장조사결과 1개 지점에서는 수맥도 분석이 잘못된 것으로 분석되었다.

A temporal database systems provides timing information and maintains history of data compared to the conventional database system. In this paper, we present a temporal relational database which use an interval-stamping method for instant-based events and for interval-based states. A set of temporal algebraic operators are developed on an instance of time and interval of time so that we can manipulate events and states at a same time. The set of operation is the basis for creating a relational algebra that is closed for temporal relations. And temporal SQL is also suggested as a temporal query relational language for our algebraic operations on temporal relations.

A literature study was conducted on the management of the pavilion of the royal tomb in the late Joseon Dynasty, focusing on "Gakneung Suri Deungnok(Records relating to the repair of royal tombs)". This study analyzed the royal tomb management system, organized the types of damage identified in the building, and examined how the damage status was recorded by type. In the above, the records related to the 1675~1713 repair of three JeongJaGak(Geonwonneung, Sungneung, and Mokneung), which are registered as state-designated cultural properties, are summarized in three aspects: management system, damage status, and expression words. The results of the study are as follows. First, the royal tomb pavilion was regularly inspected by Observator(觀察使) in spring and autumn, and Surunggwan(守陵官) every 5th, and Servant(守僕) regularly inspected every day and night, and also inspected and reported emergency cases of natural disasters or unexpected damage. Second, the damage status of each building was continuously observed and reported for the continuous maintenance of the buildings in the royal tomb. A total of 75 records of damage to the three royal tombs' pavilion were found to have been most frequently inspected, including 19 cases (25.3%), 14 cases (18.7%), 23 cases (30.7%) of the roof, and 19 cases (25.3%) of the roof. Third, the expression of the damage status is confirmed in various ways, such as separation, separation, burst, damage, excitation, moisture, leakage, and exfoliation. Among them, the main damage records were confirmed due to the separation of the base from the peeling, the furniture, cracks, leaks, leaks in the roof, and the collapse of the roof was able to check the damage records.

Basic summary of the medical administration : First of all Ming dynasty was at its last stage of dynastic era that the politics reached absolute autocracy. The influence of centralized power lead to systematical medical administration management system that was generally formed around Tai Yi Yuan(太醫院). Criticizing treatments via shamanism with supernatural powers and advent of strengthening medical concepts were steps toward a new phase. Medical education in regional areas showed drastic development and preventative medicine on epidemics as well as relief work succeeded to a certain amount. Overall Ming(明) dynasty has somewhat of a growth in some areas keeping the basics of Tang(唐) Song(宋) and Yuan(元)'s medical administration, however basically, unique contribution was not shown much. But on the other hand, measures such as common medical system, reserving incompetent doctors, positioning medical officers by the amount of contributions, paying salary with medicine instead of currency brought losses on medical development.

Defense industries which require high reliability need an optimized quality management system with well-planned implementation. And the government should examine the overall status of defense industries, then establish practical policies with a proper support plan in required areas to upgrade the quality management level of manufacturers. Thus, DTaQ developed the model for 2 years from 2014, which specialized in quality management level analysis for defense industries. And a survey has been undertaken with that model by DTaQ and Korea Research Center in 2016. The surveyed companies randomly sampled among those which have more than 30 employees and delivery history over past 3 years, and finally 106 defense industries were selected. This paper present survey method and indexes for survey of defense industry quality management level. The survey was conducted in the order of planning, data collection and data processing, and the validity and reliability of the data were verified to increase objectivity of survey results. The survey contents mainly consist of system quality and management quality. System quality includes Product Development Management, Production Operation Management, supply chain quality management, Safety & Environment Management and Reliability Management, on the other hand, management quality includes Strategic Leadership, Human Resource Management, Customer Market Management and Information & Knowledge Management. Thus this proposes the current overall quality management status of the 106 defense industries and shows level differences by company sizes and manufacturing sectors based on the result of survey. Specifically, this paper enables to track the areas which need prompt government support with the policy directions to make quality management level higher. Therefore, it is expected that this can be used as reference data in establishing quality policies for military supplies in the future.
