For scoring polygraph charts, the Prosecutors' Office of the Republic of Korea uses a consistency criterion in which an elevated signal on one physiological channel is scored as a deceptive response only if the signal is also elevated on other channels. In the current study, the effects of this scoring criterion on reliability and accuracy (validity) of polygraph scores were assessed. Polygraph tests on 26 suspects were evaluated twice by the same examiners. The examiners used the consistency criterion in the first evaluation. In the second evaluation, the examiners were prevented from using the criterion; the signals from each physiological channel were separated and randomly arranged before they were rescored by the same examiner. Reliability was assessed by the variation among the scores for each suspect. Accuracy was assessed by establishing a standard, based on a Latent Class Analysis model, using the results of polygraph tests on each of 182 additional suspects. Reliability and accuracy were both improved by the use of the consistency criterion which therefore was recommended.

Objectives：This study was designed for testing of Eating Attitude Test for Korean adolescents (EAT-26KA) on internal reliability and test-retest reliability and evaluation of each items through factor analysis. Methods：Total 1,160 middle and high school students were surveyed on June 1996. The questionnaire had been delivered by school teachers two weeks earlier before survey started. Among the 1,160 students, 114 students were selected by random. And then they were retested with same questionnaire on July 1996, four weeks later Result：Internal consistency of EAT-26KA was relatively good(Cronbach’s ${\alpha}$ =.83). There was statistically significance on test-retest reliability(r=.63 p<.01). But two items showed negative correlations(item No. 9, 17). and 5 items had low level correlation(p>.05, item No. 2, 6, 12, 21, 24). We performed factor analysis on whole items except No. 25 item. Result of factor analysis showed that the factor structure of EAT-26KA were different from that of EAT-26. Conclusion：The EAT-26KA is useful for the survey of the eating behavior and problems in Korean adolescents.

SCAI(spent CANDU fuel bundle serial number identifier) was developed to read serial numbers of spent fuel bundles in the spent fuel storage. For the purpose of effectively identifying the serial number of fuel bundle. SCAI was composed of underwater camera & light part. guiding & supporting part and control & monitor part. So it is easy to assemble and disassemble, and operate. It was tested to read serial numbers of spent fuel bundles loaded in basket during the recent spent fuel transfer campaign at Wolsong Unit 1. And it was also applied to read serial numbers of spent fuel bundles discharging from the initial core at Wolsong Unit 3 by slight change of camera and light. Inspectors could easily operate SCAI after several practices in the storage pond, which was a user friendly. And SCAI provided clear and immediate picture for identification of serial numbers of spent fuel bundles. It was interally evaluated that SCAI greatly contributed to cut inspection efforts for national and international safeguards at Wolsong power plant.

The purpose of this study was to analyze the relationship and degree of agreement between the six types of Geometry Psychological Assessment (GEOPIA) and four functions of the Myers-Briggs Type Indicator (MBTI) personality test, and to investigate the appropriate level of vocational aptitude commonly recommended by each tool. A total of 377 adult men and women from Korea, aged between 19 and 70 years, were tested using GEOPIA and the MBTI. Cronbach's alpha was calculated to verify the validity and reliability of the measuring tools, and the mean and standard deviation of each variable were calculated. Also, a cross-sectional analysis was conducted to examine the relationship between GEOPIA and the MBTI. The results showed that Round/Triangle (RT) types, Round/Box (RB) types, Triangle/Box (TB) types and Box/Curve (BC) types among the GEOPIA personality types are highly related to MBTI's Sensing/Thinking (ST) types. GEOPIA RC types were related to Intuition/Feeling (NF) and Sensing/Feeling (SF) types, and TC types were highly related to Intuition/Thinking (NT) types. Based on the common characteristics of the two tests, the findings suggest appropriate levels of vocational aptitude. Through this research, it was confirmed that GEOPIA (a Korean psychology and personality test) can be used in counseling, coaching, and education, and above all, is a reliable tool for vocational psychological assessment to search for career aptitude.

Due to the introduction of CR and DR, it has been neglected the use of the X-ray beam collimator and field size. This study examines nationwide survey of the proper use of collimator and field size by area in a specific field of plain radiography and the current status. Authors emphasized the need for the field size criteria, and propose a standard reference field size in each specific radiologic examination. Total 333 medical institutions (included in Seoul, Gyeonggi-do, Jeolla, Chungcheong, Gangwon-do, Busan area), were investigated in relation to the status of the X-ray beam collimation field size, type specific inspection areas, medical facilities, and image analyses by type to figure out whether they use the adjustment of image field to the specific examination. To assess the awareness and the impact of radiation exposure to the collimation adjustable, 168 radiographers who was working in 10 general hospitals, 10 hospitals, and 10 clinics, were surveyed how they haver adjusted the actual field size. We examine that 61.3% of medical institutions used the "Proper collimation" and only 49.9% of them employed proper one in lumbar spine densely crowded by major organs. 69% among general hospitals, and 65% among hospitals using DR system were using proper collimation. Radiographers recognized that proper adjustment of collimation could reduce the harmful radiation dose on patients. In the survey, 97.6% of respondents were aware of this fact, but only 83.3% of respondents did the adjustment of the size of the collimation field. The using of proper collimation field was low in the nationwide survey, so the effort to reduce the radiation dose on the patients is urgently needed. A unified standard for the field accompanied by thorough education should be needed.

날로 각박해져가는 사회분위기 속에서 가장 외로움을 많이 느끼는 사람들은 역시 불우한 환경에 처한 사람들, 특히 사회복지시설에 수용되어 있는 사람들일 것이다. 이들에게는 산다는 것, 생활한다는 것 자체가 커다란 짐일 수 밖에 없다. 이런 상황 속에서, 인간에게 가장 중요하다고 할 수 있는 "건강문제"는 부차적인 것으로 밀려나게 마련이다. 이처럼, 어려운 시대를 함께 살고있는 불우한 이웃을 위해 한국건강관리협회 대구지부가 사회복지시설 수용자의 건강관리를 위한 무료검진을 실시해 눈길을 모은다. 지난 7월말부터 8월초까지 실시된 무료순회검진을 통해 1천여명의 대구시내시설 아동ㆍ노인들이 검사를 받았고, 대구지부는 앞으로도 이같은 사회복지사업을 계속 펴나갈 계획이라고 밝혔다.

1. 현장 시험을 위하여 여러가지 방법이 제안되어 적용되고 있지만 그 어느것도 뚜렷한 결과를 제시하지 못 하고 있다. 2. DC test는 이미 언급된 문제로 인하여 시험목록에서 제외되어야 한다. 3. 교류 시험은 현재 많이 적용되고 있지만, 경우에 따라서는 적용이 불가능하다. 그러나 전력원에 직접 케이블 선로를 연결하는 것이 가능한 경우에는 1.732U$_{0}$ 전압에서의 시험은 타당하다고 할 수 있다(시험 시간이 명기되어야 함). 4. 진동파 시험은 충분히 민감하지 않지만, U$_{0}$하에서 PD측정을 병행하면 타당한 방법이 될 수 있다. 5. HV 케이블에 있어서 다른 방법(VLF와 SI)의 적용은 더 구체적으로 연구되어야 한다.

요즈음 동남아 각국의 사람들이 우리나라에서 근로연수를 받기 위해 입국하고 있다. 60~70년대에 우리나라 사람들이 해외 취업을 위해 떠나던 때를 생각하면 우리의 국력도 국제적으로 많이 신장되었다는데 대한 뿌듯한 느낌을 갖는 사람들도 있을 것이다. 이들 외국인 근로 연수생 글은 입국 즉시 며칠간의 교육을 받은 후 국내 중소기업체에서 기술 연수를 받도록 배치된다. 한편 이들을 관리하고 있는 중소기업협동중앙회는 이들의 건강과 건전한 연수를 위해 자비를 들여 연수생에 대한 건강검진을 지난 9월부터 실시하고 있다. 연수생뿐만 아니라 내국인의 건강을 위해서라도 반드시 필요한 검진이라는 평가를 받고 있는 이 검진사업의 실시 과정과 이를 주관하고 있는 중소기업협동중앙회에 대해 소개한다.

한우의 번식에 있어서 번식효율을 증진하기 위해서는 정확한 수정적기의 선택과 수정 후 가능하면 조기에 임신감정을 실시하여 공태기간을 최소로 단축시켜 번식우의 효율을 증진하고 송아지 생산비를 줄여야 할 것이다. 임신감정은 일반적으로 인공수정사나 수의사가 직장검사를 통해 태아를 확인하는 방법이 있으나, 이 방법은 수정 후 50-60일 이후부터 가능하며 숙련자에 따라 진단율이 다르며 암소에게 스트레스를 주고 태아나 난소에 손상을 주거나 심하면 태아의 조기폐사 등의 부작용이 있으며 진단율도 2-3만원 정도 소요된다. 최근 임신진단을 현장에서 간단히 조기에 진단할 수 있는 새로운 방법이 개발되어 있어 소개하기로 한다.
