Electroencephalograph(EEG) information, which is an important data of brain science, reflects various levels of information from the molecular level to the behavior and cognitive stages, and the explosively amplified information is provided at each stage. Therefore, EEG information is an intrinsic privacy area of an individual, which is important information to be protected. In this paper, we apply spring security to web based system of spring MVC (Model, View, Control) framework to build independent and lightweight server system with powerful security system. Through the proposal of the platform type EEG analysis system which enhances the security function, the web service security of the EEG information is enhanced and the privacy of the EEG information can be protected.

In order to remove particulate matter, functional construction materials are developed. However, there is no evaluation method and infrastructure for particulate matter removal rate. Therefore, the purpose of this study was to build a particulate matter removal rate test chamber and to present a method for particulate matter removal rate. As a result, since construction materials have effectiveness in an environment where particulate matter is generated, the particulate matter injection step was proposed as a comparison target. The evaluation of the particulate removal rate was proposed by relative comparison of the slope values obtained by linear regression analysis for all concentration values measured in the particulate matter injection step. In linear regression method, all measured values can be evaluated, and the variability can be evaluated with the coefficient of determination (R-square), so that the reliability of the particulate matter removal rate can be secured.

This paper proposes a software tool MADE that is useful to develop a practical Korean morphological analyzer. A morphological analysis is performed by using adjacency conditions provided by a morphological dictionary. This means that developing a morphological analyzer is reduced merely to constructing a morphological dictionary. No programming skill is required in this process, MADE provides with useful functions that facilitate the construction of a dictionary. Once a dictionary is constructed, the morphological analysis engine embedded in MADE may be used as a stand-alone morphological analyzer or be integrated into an application software which requires a Korean morphological analysis module.

최근 몇 년 사이에 자연친화적인 하천복원의 관심이 고조되면서 자연형 하천공법의 적용 초기단계를 걷고 있는 우리나라에서는 생태계 복원과 더불어 인명과 재산을 보호할 수 있는 안전한 자연형 하천 공법의 개발을 위해 수리적 안전성을 지속적으로 관찰하고 분석할 필요가 있다. 그러나 아직까지 우리나라에서는 수리적 및 치수 방재적 측면에서 자연형 하천공법의 안전성에 대한 표준화되고 일관된 분석체계가 아직 구성되지 못하여 자연형 하천정비 공법의 실무적용에 많은 어려움을 겪고 있다. 더구나 소하천 유역은 지역적 특성이 두드러지고 계절에 따른 유량변화가 심하여 하천의 수리적 안전에 대한 분석체계가 적절하게 갖추어지고 있지 못하는 실정이다. 따라서, 본 연구에서는 자연형 하천공법에 따른 소하천의 수리적 안전성과 하천정비 전$\cdot$후의 치수기능의 변화를 Hec-Ras(river analysis system)를 이용하여 적용대상 유역의 수리$\cdot$수문학적. 기하학적, 기상학적 자료들 기본으로 대상유역에 모의해 보았으며 그 결과로부터 자연형 하천정비 전$\cdot$후의 수리적 안전성을 해석하고 하천의 치수기능에 대한 자료를 얻고자 하였다. Hec-Ras를 이용한 연구의 결과 값들은 국내에서의 자연형 하천공법 적용에 따른 하천의 수리적 안전성을 판단하는 표준화된 분석체계를 마련하는데 기초 자료를 제공할 것이며 자연형 하천정비의 기준과 적용을 확립하는데 중요한 의미를 가질 것으로 판단된다.

BACKGROUND: As a result of rural exodus, aging of rural population, development of high-yield rice varieties and so on, abandoned paddy fields of South Korea have generally increased. The phytosociological studies are needed to recommend the effective vegetation management methods of abandoned paddy fields. The current study performed an analysis of vegetation characteristics by classifying plant communities for abandoned paddy fields in South Korea. METHODS AND RESULTS: A comparative analysis of syntaxonomy, synecology, and syndynamics was performed by using the Z.-M. method of phytosociology and vegetation survey which was obtained from an enumeration district of total 203 phytosociological releves of 5 regions in Gangwon-do, 5 regions in Gyeonggi-do, 2 regions in Chungcheong-do, 18 regions in Gyeongsang-do, and 10 regions in Jeolla-do. Alopecurus aequalis community, Juncus effusus var. decipiens community and Salix koreensis community were, respectively, identified as successional plant communities of the early stage, the middle stage, and the late stage in the vegetation of abandoned paddy field. Sere of abandoned paddy field can be classified, developmentally, into annual plant stage, perennial plant stage, shrub plant stage, and forest tree stage. Several kinds of dominant species rather than a distinct species were found in the middle stage of abandoned paddy field. CONCLUSION(S): In this study, changing pattern in vegetational communities of abandoned paddy field were understood. These results will provide important information for restoring and conserving the ecology of fallow ground.

The main purpose of the archives is to maintain a history of the organization's functions and activities. Selecting valuable records for the permanent archives through objective appraisal from among many records that reflects the activities of organization is very important but also very difficult. The quantity and complexity of comtemporary records has rapidly expanded because of electronic storage, and with the information environment, and it is now possible to manage and control the records an entire lifetime. In this study, it is proposed the appraisal methods based on a business analysis that is combined the macro-appraisal factor and micro-appraisal factor; The former is functions and organizations as the objective guideline of selecting valuable records from the beginning and the latter is a contents appraisal (evidential value) of the individual records.

This study randomly assigned 24 middle-aged women to determine the effect of a 12-week combined exercise program on cardiovascular function and electrocardiogram-based ST segment and QRS in obese middle-aged women. Analysis of the results was conducted to verify differences within groups and between periods and groups. In terms of cardiovascular function, myocardial oxygen consumption showed a significant decrease in the experimental group during the resting phase and the highest intensity phase during exercise, and an interaction between group and period at rest was also observed. The heart rate recovery rate showed a significant decrease in the experimental group at 2 minutes of recovery, while in the control group, on the contrary, a significant increase was observed. The experimental group showed a significant decrease in systolic blood pressure, and an interaction between group and period was also observed. There was no change in diastolic blood pressure in both the experimental and control groups, and there was a statistically significant decrease in pulse pressure only in the experimental group at the 3-minute recovery stage. In the case of the electrocardiogram, the QRS height in the experimental group showed a significant increase in most cases at rest and at 3, 6, and 9 minutes during the recovery period, while there was no significant difference in the QRS period in both the experimental and control groups, and the ST segment height was significantly increased at rest in the experimental group. appeared to have increased. Therefore, summarizing the results of this study, it is believed that the 12-week combined exercise program has a positive effect in improving cardiovascular function, ventricular contractility in electrocardiograms, and myocardial ischemia in obese middle-aged women.

Records management refers to a series of activities to achieve the goal of securing transparency in administration and safely preserving and utilizing records. Each process of record management is largely divided into production, preservation and management stage. The reporting system of record production has an important fuction that serves as a bridge between production stage and preservation and management stage. It was established after the enactment of the Act on Records Management of Public Agencies in 1999, to grasp the state of production and management of records of various organizations. Since then the National Archives of Korea(NAK) has been able to rather actively understand the situation of records and acquire them than simply collect them. The Act, which was revised in 2006, regulates electronically automated reporting methods in which the production reporting datas are generated in the record creation system and transferred to the record management system. Despite improvements in the system, electronic reporting methods are being used in part. The 713 public institutions have submitted reports of record production to the NAK in 2017, and this study analyses them of only 47 central administrative agencies, including departments, offices, agencies, and committees. Their reports have 15 forms which consist of production statistics and inventories of 7 types of records including general records, survey, research, review, minutes, shorthand, audiovisual records, secret records, government publications. This suggests implications for improving the reporting system of record production.
