This study is proposed to suggest the preventing methods for correctional officer's mental health problems. For this purpose, Delphi method was used and the study panel was composed of finally 10 people. Total Delphi process was performed for 4 times and six qualified researchers & skilled correctional officers participated in developing Delphi questionnaires. As the main results, major correctional officer's mental health problems are PTSD(post traumatic stress disorder), job stress, suicide witnessing, stress from violent accidents, and anger by related with their own work. All of these problems must need to be managed. Besides, the most effective preventing method for correctional officer's mental health problem is providing regular counsels & treatments with a psychiatrist or the fully qualified experts. The mental health promotion strategies for correctional officers must be settled for providing appropriate mental health services to them.

최근 대규모 지역 혹은 전 지구에 걸친 분석 및 모니터링을 위한 위성영상의 사용이 늘어나면서 이를 처리하기 위한 효율적인 '영상좌표 상호등록'법이 요구되고 있다. 이에 본 연구에서는 일반적으로 오랜 시간이 소요되는 '영상좌표 상호등록'의 효율성을 높이기 위해 '사전검수영역기반정합법'(Pre-qualified area based matching)을 사용하였다. 이를 통해 '영상좌표 상호등록'시 연산시간을 현저히 단축시켰고 추출된 정합점에 과대오차제거법을 적용함으로서 단순히 영역기반정합법을 적용한 경우에 비해서 정확도가 향상됨을 확인할 수 있었다. 제안한 알고리즘을 이용하여 테스트 프로그램을 작성, 한반도 Landsat ETM+ 영상 3장을 이용하여 테스트하였다. 정합점 간의 평균제곱오차는 0.436 영상소, 정합점은 평균 38,475개로 나타났다. 연산시 간은 평균 약 8분으로 나타났다.

Introduction: Khon Kaen Cancer Registry (KKCR) was established in 1984. KKCR aims to collect all cancer cases in Khon Kaen Province. The poorly qualified data may lead to distort the cancer burden and misinterpretation of policy maker. Objective: To assess data quality in childhood cancer between 1990 and 2007 in Khon Kaen Province, Thailand. Materials and Methods: Data of childhood cancer cases aged less than 20 years diagnosed during 1990-2007 were retrieved from the population-based data set of KKCR. All childhood cancer data were verified before data entry. Internal consistency, percentage of morphological verification (MV%) and cancer cased of the basis of diagnosis by death certificate only (DCO%) were evaluated. The age-adjusted rate (ASR) was calculated by standard method. Results: The data of childhood cancer from KKCR is acceptably qualified which reflects the quality of the whole registration.

A new system for automatic interpretation of the awake electroencephalogram(EEG) was developed in this work. We first clarified all the necessary items for EEG interpretation in accordance with an analysis of visual inspection of the rhythms by a qualified electroencephalographer (EEGer), and then defined each item quantitatively. Concerning the automatic interpretation, we made an effort to find out specific EEG parameters which faithfully represent the procedure of visual interpretation by the qualified EEGer. Those specific EEG parameters were calculated from periodograms of the EEG time series. By using EEG data of 14 subjects, the automatic EEG interpretation system was constructed and compared with the visual interpretation done by the EEGer. The automatic EEG interpretation thus established was proved to be in agreement with the visual interpretation by the EEGer.

The Korea Electric Power Research Institute (KEPRI) has developed performance demonstration programs for non-destructive testing personnel who analyze ECT(eddy current testing) data for steam generator tubing since 2001 The purpose of these performance demonstration programs is to ensure a uniform knowledge and skill level of data analysts and contribute to safe operation of nuclear power plants. Many changes have occurred in non-destructive testing of steam generator tubing such as inspection scope, plugging criteria and qualification requirements. According to the Notice 2004-13 revised by the Ministry of Science and Technology (MOST), the analyst for steam generator tubing shall be qualified as the qualified data analyst (QDA), and the site specific performance demonstration (SSPD) program shall be implemented. KEPRI developed these performance demonstration programs and they are being successfully implemented. The analyst's performance is expected to be improved by the implementation of these programs.

US NRC issued rulemaking of 10CFR50.55a to perform the Perservice and Inservice inspection for Reactor Vessel Head Penetration Nozzle of US Nuclaer plant. The rulemaking was required the EPRI Demonstration to verify the NDE technique performing special Ultrasonic examination. In order to meet this requirement, the UT and ECT procedures was demonstrated and the NDE personnel were qualified by EPRI. In this paper, the NDE technique and analysis method are described the Preservice inspection for the Palo Verde #1/2/3 Replacement Reactor Vessel Head Penetration Nozzle using the qualified procedures and personnel.

There are three items, which are panhead displacement, tilting angle of pan head, required moment of main shaft, which representing kinematic performance of pantograph. Kinematic variables effective on kinematic performance are length of each components and installation angle, In this study, cost function is defined with 3 items, By this cost function, length of thrust rod was optimized. Finite element analysis was used to consider structural soundness. Finite element model was qualified by comparison between analysis result with experiment result. By qualified F.E, model various severe condition was simulated to consider structural soundness.

The number of North Korean refugees entering South Korea since the mid 1990s has increased continuously and recently the number has reached 2 million people, which is expected to continue to rise. In the meantime, the government of South Korea has been developing various means to help the North Korean refugees take part in our society and to increase their self-reliance. In this study, improvements were made to systems where North Korean national qualifications are made eligible for use in South Korea, to help them better adapt to our society. The research conducted a Delphi survey of 70 professional qualified workers, training specialists, qualified professionals, researchers and government agents, and 6 interviews were carried out to North Korean refugees and qualified judges. The results complement the current system, in terms of eligibility qualification procedures, where the department's role in its qualification procedure is enhanced and practical experiences are added to the procedure.

In the next generation Internet(NGI) based on dense wavelength division multiplexing(DWDM) technology, QoS RWA considering various QoS parameters of DWDM networks is regard as one of the key issues in providing real-time multimedia services. However, finding a qualified path meeting multi-constraints is generally NP-complete problem. It is insufficient for QoS RWA researches in DWDM networks that must consider QoS parameter as well as wavelength-continuity constraint. This paper proposes qualified path routing (QPR) algorithm with minimum computation and implementation complexity based on flooding method to accomplish QoS routing and wavelength assignment (RWA). We also introduce a QoS-based RWA mechanism considering multi-constraint such as optical signal quality attributes, survivability and wavelength-continuity constraint combined with proposed routing algorithm. Simulation results show superior efficiency of the proposed algorithms in terms of blocking probability, routing overhead and survivability ratio.
