서울시 모대학교에서 자판기를 운영하는 S씨. 그는 둘째가라면 서럽게 자판기를 관리를 철저히 하는 사람이다. 하루가 멀다 하고 자판기를 점검해 소비자들이 정말 깨끗한 커피를 마실 수 있게 하는데 신경을 쓴다. 이러지라 매번 자판기 위생문제가 매스컴을 통해 불거질 때마다 억울한 생각이 절로 든다. 얼마 전에도 매스컴에 자판기 위생 불량 문제가 불거져 매출이 크게 준바 있다. S씨는 이대로 있어서는 안 되겠다는 생각이 들었다. 그래서 서울시가 진행하는 안심자판기 참여 업체로 신청을 했다. 서울시의 안심자판기 점검 표시판을 받아 부착을 하고, 관리지침에 따라 자판기를 관리하기 시작했다. 점검판에 원재료의 유통기간, 보충일자, 제조국가 등을 표시하기 시작했고, 내부 점검 결과도 기록하기 시작했다. 서울시의 안심자판기 점검표가 부착이 된 탓인지 매출이 늘었다. 이에 고무된 S씨는 서울시가 여러 가지의 내부성능을 체크해 최고의 위생자판기에게 내준다는 마크 인증도 신청하기로 했다. 이같은 S씨의 사례는 서울시가 추진하는 안심자판기에 대한 이해를 돕기 위해 가상의 스토리텔링이다. 서울시가 왜 자판기 위생문제에 적극 관심을 갖고 안심자판기 사업을 진행하는 지, 또 앞으로 어떻게 세부 정책 마련이 이루어질지 큰 관심사가 아닐 수 없다. 서울시가 진행하는 안심자판기에 사업 방향을 따라가 봤다.

This study is aimed to suggest the method, color channel seperation, can match the common points in real-time automatically. Image coordinates which was calculated from the acquired image with CCDcamera in this study is checked with two methods; check the accuracy of image coordinate and common point matching through correct sort. In conclusion of check, The RMSE of object coordinate which is calculated by photogrammetry program with image coordinate is in the expect RMSE of close-range photogrammetry, and Match-ing of common point is also performed correctly by using sort. For these reason, this color channel separation method is adequate for the acquisition of accurate image coordinates and the matching of the common points. I think that this method will be useful for the fields of industry which need fast-correct processing with acquired information in real-time.

관개배수를 수행하는 농업용 수리시설물은 소규모이고 개소수가 많아 효율적으로 관리하기가 어려우며, 넓은 지역에 분포하고 있어 시설 현황의 파악조차 쉽지 않다. 농업용 수리시설물은 점검자가 관리항목을 종이 조사표에 수기로 작성하여 시설상태를 점검하고 있기 때문에 자료의 누락 및 오류, 전산화를 위한 재입력 과정 등에 있어서 어려움이 발생할 수 있다. 이러한 시설물을 효과적으로 관리하기 위해서는 정보망을 구성하여 원격으로 관리하거나, 직접 시설물을 돌아보며 관리해야 한다. 전자의 경우에는 비용이 많이 들기 때문에 적은 수의 관리지점을 제어하는 데는 유리하나, 농업용 수리시설물과 같이 개체수가 많을 경우에는 적용이 어렵다는 단점이 있다. 본 연구에서는 농업용 수리시설 점검 및 관리의 편의성, 효율성을 제고하기 위하여 농업용 수리시설물에 대하여 점검표준코드를 설계하였으며, WSN (Wireless Sensor Network) 기반의 점검기술 (RFID 및 QR코드)을 개발, 현장 적용을 통하여 활용성을 평가하였다. WSN 기술을 바탕으로 빠르고 정확하게 시설물을 인식할 수 있으며, 식별한 시설물의 정보를 바탕으로 현장에서 시설물에 대한 적절한 대응이 가능하도록 설계하였다. 개발한 기술은 대한민국 이동 지구의 시설물을 관리하는 데 직접 이용함으로써 평가하였다. 본 연구는 기존 농업용 수리시설물 점검의 비효율성을 개선하고 시설물 안전 평가 및 현장 이력 관리 등 현장 업무 효율 향상을 통해 농업용 수리시설 관리 및 농업용수 관리에 기여하는 바가 클 것으로 기대된다.

Purpose: To improve the quality of the statistical analysis of papers published in the Journal of the Korean Society for Therapeutic Radiology and Oncology (JKOSTRO) by evaluating commonly encountered errors. Materials and Methods: Papers published in the JKOSTRO from January 2006 to December 2007 were reviewed for methodological and statistical validity using a modified version of Ahn's checklist. A statistician reviewed individual papers and evaluated the list items in the checklist for each paper. To avoid the potential assessment error by the statistician who lacks expertise in the field of radiation oncology; the editorial board of the JKOSTRO reviewed each checklist for individual articles. A frequency analysis of the list items was performed using SAS (version 9.0, SAS Institute, NC, USA) software. Results: A total of 73 papers including 5 case reports and 68 original articles were reviewed. Inferential statistics was used in 46 papers. The most commonly adopted statistical methodology was a survival analysis (58.7%). Only 19% of papers were free of statistical errors. Errors of omission were encountered in 34 (50.0%) papers. Errors of commission were encountered in 35 (51.5%) papers. Twenty-one papers (30.9%) had both errors of omission and commission. Conclusion: A variety of statistical errors were encountered in papers published in the JKOSTRO. The current study suggests that a more thorough review of the statistical analysis is needed for manuscripts submitted in the JKOSTRO.

This study was conducted to provide practical ways to apply interview assessments in classrooms. Interview assessments have been asserted to serve as one of the alternatives to the traditional paper-and-pencil tests. In order to propose ways for teachers to actively use interview assessments for mathematics assessments, relevant instruments were developed by analyzing a number of related theories. These instruments were developed in two forms: interview assessments focused on identifying student characteristics and those focused on identifying thought processes. The interview assessments were applied in classroom settings and the results of this application were analyzed. The findings from this study are expected to suggest beneficial implications for teachers who are interested in practicing interview assessments in classrooms.

This study shows the difference between groups with multivariate analysis of fire prevention activities, special investigations of fire safety, and fire safety management according to the management method of apartment houses and the inspection of firefighting facilities. The results of the analysis are as follows. First, there was a significant difference in fire prevention activities according to the quality of inspection of firefighting facilities. This means that fire prevention is high if the fire safety manager's ability to inspect firefighting facilities is excellent and the fire safety inspection is conducted in accordance with national fire safety standards and checklists. Second, there was a significant difference in the fire safety special investigation according to the management method of the apartment buildings. The manual operated by the management entity and the management entity's management and execution help the organization members to expedite work. This expedition of work creates a high possiblity to get a good evaluation from the special investigation of fire safety. Third, analysis of fire prevention activities showed a significant interaction between the inspection of firefighting facilities and the management method of apartment buildings. The analysis shows that that there is a positive correlation between the level of fire prevention and both the fire safety manager's ability to inspect firefighting facilities and the degree to which the inspection is conducted to meet national fire safety standards.

This study aims at developing an easily-applicable Sanitation Standard Operating Procedure(SSOP) program for Fresh raw-fish manufacturing. It compares the sanitation inspection results of SSOP-program-applied procedure and non-applied procedure. The samplings for bacteriological examination were collected from the touching surface of food and from the personal workers. The sanitation status was recorded in the check-up list. The results were statistically analyzed to ascertain the efficiency of the SSOP program. The present official KFDA check-up list for sanitation inspection is composed of 51 items. Each item is judged to be fit or unfit to the standards. When the unfit items are more than 6, the work-place is judged to be insanitary. But in this study, the results of sanitation inspection are scaled in points in the 70％ allotment, and the results of bacteriological examination are scaled in points in 30％, totaling 100％. Below 60 scores are judged to be insanitary and administratively punished; 61-75 scores are judged to be average; 76-85 good; above 86 excellent. The sanitation inspection scores by the improved check-up list went up by two grades from 71.8 (before SSOP program) to 88.6 (after SSOP program). The results of bacteriological examination also improved from 57.5 to 98.2. The total scores of both results converted in the allotment of 70％ and 30％ also showed an improvement by two grades from 66.4 (before SSOP program) to 93.4 (after SSOP program). The above results show that the manufacturers participated in this study are following the 8 essential sanitary procedures which are needed to anchor the HACCP system.
