본 연구는 일반적인 수문모형 및 수자원 관련 모형들의 초기세팅시 모형별로 사용되는 각기 다른 형태의 입력자료 대한 활용성을 용이하게 하고 실제 시스템에 적용하여 모형의 활용성을 높이고자 하는데 있다. 특히 현재 한국수자원공사 데이터베이스의 수문자료는 각종 수문모형 및 수자원 관련 시스템에 직접 사용하기에는 모형의 입력 포맷 형태가 너무나 다양하기 때문에 그 한계가 있다. 자료의 형태 대부분이 Raw data의 형식으로 이루어져 있어 모형 입력을 위한 선행 자료처리가 불가피하며, 이로 인해 실질적인 유출해석의 정확성을 높이는 연구 또는 수문학적 분석을 위한 연구등의 학술적인 측면에 초점이 맞추어지기보다 오히려 입력자료 구축에 많은 시간이 투입되는 것이 사실이다. 그 예로 실시간 물관리 운영 시스템(IRWMS)에서 유역유출 모형으로 사용 중인 SSARR모형의 강우 입력자료로는 유역평균강우량(MAP)이 사용된다. 한편 데이터베이스에는 지점 강우자료가 저장되어 있으며, 이를 사용하기 위해서는 다시 티센법(Thiessen Method), 유역평균법 등을 이용하여 지점강우에서 MAP로 환산 후 활용해야한다. 또한 이러한 선행 작업들은 모형 수행자마다 반복적으로 이루어지는 작업이므로 변환 프로그램에 의해 자동으로 계산하여 DB 등에 저장하고 사용한다면 수문자료 분석에 소모되는 시간과 비용을 절감할 수 있을 것이다. 현재 데이터베이스 내부에는 이러한 자료변환 알고리즘이 포함되어 있지 않으며 원시자료인 지점 강우자료가 데이터베이스에 저장되어 활용하고 있다. 따라서 수자원 전문가들에게 분석하고자 하는 유역별 모형별로 입력자료의 형태가 변환되어 자료를 실시간으로 제공하고, 또한 전산전문가가 아닌 수자원 전문가에 의해 관리 될 수 있는 데이터베이스 관리프로그램이 필요하다. 이러한 데이터베이스 관리프로그램의 역할가운데 주요사항으로 수문 자료를 활용한 수자원 관련 프로그램에 해당 실무 차원에서 작성, 검토, 사용을 위한 수자원 공사의 Raw Data 가공이 사용자의 요구에 따라 이루어져야 한다. 사용자의 요구에 따라 가공된 데이터는 다시 데이터베이스에 저장되어 다른 모형에서 해당 자료를 필요로 하게 될 경우 사용자들은 데이터를 손쉽게 받아 사용할 수 있다. 저장된 자료들은 검$\cdot$보정 기능을 포함하여 신뢰성을 확보하고 유출모형의 입력자료를 동일한 수준으로 유지하게 된다. 특히 IRWMS(Integrated Real-time Water Manage System)를 물관리 센터에서 실질적으로 운영하기 위해서는 신뢰성 있는 수문자료의 확보가 반드시 필요하다. 초기 입력자료의 신뢰성에 따라 시스템 전체에 미치는 영향이 상당히 크기 때문이다. 따라서 이러한 수문자료 연산 프로그램(JydroDB Solution)은 수문자료의 신뢰도를 분석할 수 있을뿐만 아니라 IRWMS 내부의 여러 모형과 연동이 가능하도록 개발하였고 수자원 전문가에 의해 테이터베이스관리가 손쉽게 이루어지도록 구성하였다.

The purpose of this study is to develope a case management education program for employees in the long-term mental health care facilities to reflect strength perspective and analyze the program's effectiveness. The participants in this study were 30 employees working in the long-term mental health care facilities in Seoul and Gyeong-gi regions(15 each), and the program's effectiveness was verified with those participants. The total 13 sessions of the education program was offered: three hours per session, and one session a month. The perception on clients(social distance, attitude towards mentally disorder people) and workers' competence(burnout, empowerment) were used as the measuring tool to verify the effectiveness of case management education. For data analysis, technical statistics and t-test were used in this study. As a result of the analysis, the social distance between the employees in the long-term mental health care facilities who participated in the case management education and clients decreased in relation with perception on clients, and attitude score towards clients improved. It was also verified that burnout decreased, and that empowerment improved in relation with the competence of the employees in the long-term mental health care facilities.

This study was conducted to investigate the optimal management interval in 33 healthy adults by observing changes in oral health on the basis of the plaque control index and gingival index. When plaque control score was compared according to the period, it was found that oral hygiene management was the best in the fourth visit (p<0.05). Improved oral hygiene status was observed during the 3- and 6-month follow-up (p<0.05). Regarding gingival index, the fourth visit showed the healthiest gingival status (p<0.05). At the 3-month follow-up, the gingival index worsened, but a healthy gingival status was attained by 6-month follow-up (p<0.05). The plaque control score according to interest in dental health showed that the 'interested' group had good oral hygiene management (p<0.05). As a motivation for oral hygiene status and gingival health, examination with a 'phase contrast microscope' in the first visit and calculation of the 'evaluation index' in the follow-up visit tended to improve the patients' ability for oral hygiene management (p>0.05). The questionnaire survey showed, that the optimal management interval was 1, 3, and 6 months. As a result, with the effective management interval for the preventive management program focused on professional mechanical tooth cleaning, which was administered weekly, the maximum ability for oral hygiene management was attained at the fourth visit. The effective management period was 1 month. The use of a phase contrast microscope and the calculation of the evaluation index for oral hygiene management could influence the motivation to improve oral hygiene management.

Facilities Management(FM) System is widely spread GIS applications introduced in local governments. Over the last few years many local governments in Korea have developed facilities management systems, especially for underground facilities(drinking water and sewerage) and road management systems. The concept of Standardized Facilities Management Software(SFMS) was developed to minimize the duplication of efforts in local governments. Recently local governments try to change their direction to Urban Information Systems(UIS) which can comprehensively manage their information project carried out by each sector. Therefore this study suggests a method for introducing a Standardized Facilities Management Software to help constructing urban information system. This method is expected to prevent double investment, reduce project time, minimize the risk of project failure, and activate information projects.

Dental caries and periodontal disease are considered to be chronic, but can be prevented through an incremental oral health program covering all ages. The National Oral Health Program for adults provides oral health exam and scaling, and is covered by national health insurance for those over 20 years of age in Korea. The aim of this study was to collect basic data for developing an oral health program for adults by identifying factors related to awareness and need. The data were obtained by convenience sampling of 303 subjects. The use of dental plaque disclosing agents affected tooth brushing frequency, toothbrushing time and use of oral auxiliary devices. Education on toothbrushing methods affected toothbrushing time and use of oral auxiliary devices. Of those surveyed, 93.1% replied that an incremental oral health program for adults was needed, and 68.0% intended to participate. In a regression model, the factors that had an effect on the perceived need for an oral health program were education level, use of oral hygiene auxiliary devices, and toothbrushing time, and the factors affecting intent to participate were education for prevention of periodontal disease and the use of oral hygiene auxiliary devices. The subjects stated that the following oral health programs were needed: an oral bacteria exam (74.3%), toothbrushing education (71.6%), a bad breath exam (69.3%), education on use of oral hygiene auxiliary devices (46.9%), a dental plaque exam (42.9%) and a saliva exam (37.6%). Oral health education appears to be an important factor for participation in an incremental oral health program.

This study aims to suggest an improved groundwater management plan for future policy decisions in Korea by examining representative groundwater management cases abroad. In the United States, the Ground Water Resources Program is operated both locally and regionally. In order to manage appropriate levels of groundwater in Japan, groundwater resource management programs are conducted according to small, medium, and large watersheds. In Europe, the watershed unit manages groundwater and surface water by way of an integrated approach. In Korea, groundwater development at the national level is designated and managed in a top-down manner, whereas in the United States and Japan, groundwater is managed from small-scale regional units to large-scale watersheds. In order to evaluate the sustainability of groundwater resources, groundwater must be evaluated through a dynamic process including continuous monitoring, groundwater flow analysis, and management priorities.

기존 농업용저수지는 농업용수 공급이라는 단일한 목적으로 비교적 간단하게 운영되어왔다. 그러나 둑높이기사업 후 기존 농업용수를 공급함과 동시에 하천유지용수를 연중 공급해야 하기 때문에 경험적 물관리로는 갈수기간 동안의 물관리 및 홍수기 동안의 저수율 조정 문제를 해결할 수 없다. 따라서 기왕의 경험적 용수공급에서 탈피하고 가이드라인에 의한 공급이 이루어져야 용수목적별 공급이 원활하게 이루어질 수 있으며, 이를 위해서는 물수지 분석 등 기술적으로 분석해야하는 과정을 종합하여 관리자가 쉽게 운영할 수 있도록 의사지원체계가 구축되어야 한다. 본 연구는 둑높임저수지 운영데이터를 구축하고 저수지 운영곡선을 프로그램화 하여 현장 계측데이터를 연계한 물관리 의사지원 시스템을 개발하였다. 본 시스템은 지리정보시스템을 기반으로 작성되었으며, 운영물수지 프로그램이 모듈로 구축되어 농업용수와 하천유지용수 등 용수목적별로 월별 공급량을 계획하여 운영자 및 유관기관에게 제공하는데 있다. 기존 설계용량산정 프로그램을 기반으로 운영에 필요한 운영 물수지분석 모델을 개발하였으며, 이를 기반으로 둑높임저수지의 일부 사업지구에 대한 운영곡선을 프로그램화 하였다. 시스템 개발은 분석에 필요한 정보를 DB화하고, 이를 활용한 운영물수지분석, 운영곡선 모의 등을 수행할 수 있도록 구축되었다. 물관리 센터-현장을 연계하여 운영할 수 있는 의사지원 모듈 즉, 센터에서 운영기준과 운영계획량을 수립(모의)하고, 이에 따라 조견표, 개도율로 현장을 운영할 수 있도록 단순화하였다. 추가적으로 스마트 단말기를 통해 홍수기 업무지원이 가능토록 기능을 구현하였다. 본 시스템은 가이드라인에 의한 농업용저수지 운영관리라는 관점에서 유일한 시스템으로 유역별 환경변화 인자와 현장운영 경험치를 적용한 첫 번째 사례이다. 또한 관행적 물관리에서 탈피하여 과학적 수자원 관리로 국가 물관리 정책수립에 필요한 의사결정지원에 활용될 예정이다.
