Currently, Japan is undertaking a nationwide project to measure and map radioactive contamination around Fukushima, as part of the efforts to restore normalcy following the nuclear accident. The Japan Atomic Energy Agency (JAEA) manages the Fukushima Environmental Safety Center, located approximately 20 km north of the Fukushima Daiichi nuclear power plant in Minamisōma City, Fukushima Prefecture. In collaboration with the JAEA, this study involved conducting comparison experiments and analyses with radiation detectors in high radiation environments, a challenging task in Korean environments. Environmental radiation surveys were conducted using three types of detectors: CZT, NaI(Tl), and LaBr₃(Ce), across two contaminated areas. Dose rate values were converted using dose rate conversion factors for each detector type, and dose rate maps were subsequently created and compared. The detectors yielded similar results, demonstrating their feasibility and reliability in high radiation environments. The findings of this study are expected to be a crucial reference for enhancing the verification and supplementation of procedures and methods in future radiation measurements and mobile surveys in high-radiation environments, using these three types of radiation instruments.

Background and Objective : Most diagnostic method for numbness were invasive and complex. So we need to simplify and objectify diagnostic method for numbness. Some study with EAV which is one of Physiological Signal Measuring Instruments, report significantly result as objective diagnostic method for other clinical symptom. By using EAV, we have obtained some physiological signal data from meridian-acupoints of 58 numbness cases. Objective and Methods : This study researched into the clinical statistics for 58 case who ware in numbness, and they ware treated with oriental medical care at the Dong-shin university oriental hospital during 1 year from April 3 2000 to March 30 2001. The data were analyzed and interpreted to compare with traditional differentiation of symptom-complexes, then further evaluated as the Five Evolutive Phases to make them differentiated. The EAV valus of Five Evolutive Phases were identified with the sequence of wood(木), fire(火), earth(土), steel(金), water(水). Results and Conclusion : These values of physiological signal were identical with standard differentiation of symptom-complexes of numbness which is the main cause of dishannonious flow of Qi and blood of the in the liver and deficiency of Qi and blood of the bladder with stagnancy of dampness. Among Five Evolutive Phases, Earth and wood values were increased, steel, fire and water were decreased significantly. This data imply the possibility of somewhat generalization from measuring instruments.

PURPOSE. A recently introduced direct drill-guiding implant surgery system features minimal tolerance of surgical instruments in the metal sleeve by using shank-modified drills and a sleeve-incorporated stereolithographic guide template. The purpose of this study was to evaluate the accuracy of this new guided surgery system in partially edentulous patients using geometric analyses. MATERIALS AND METHODS. For the study, 21 implants were placed in 11 consecutive patients using the direct drill-guiding implant surgery system. The stereolithographic surgical guide was fabricated using cone-beam computed tomography, digital scanning, computer-aided design and computer-assisted manufacturing, and additive manufacturing processes. After surgery, the positional and angular deviations between planned and placed implants were measured at the abutment level using implant-planning software. The Kruskal-Wallis test and Mann-Whitney U test were used to compare the deviations (${\alpha}=.05$). RESULTS. The mean horizontal deviations were 0.593 mm (SD 0.238) mesiodistally and 0.691 mm (SD 0.344) buccolingually. The mean vertical deviation was 0.925 mm (SD 0.376) occlusogingivally. The vertical deviation was significantly larger than the horizontal deviation (P=.018). The mean angular deviation was 2.024 degrees (SD 0.942) mesiodistally and 2.390 degrees (SD 1.142) buccolingually. CONCLUSION. The direct drill-guiding implant surgery system demonstrates high accuracy in placing implants. Use of the drill shank as the guiding component is an effective way for reducing tolerance.

The purpose of this study is to construct a structural equation model and to analyze causal relationships among variables related to attitudes to science using structural equation modeling(SEM) with LISREL VII. The sample consisted of 483 10th grade boys from a general high school in Pusan, Korea. The questionnaires (ABC-attitude scale: affection, behavioral intention, cognition scale of attitude towards science) were developed by the researcher through a pilot study. And other instruments have modified previous ones. Five instruments were used in this study: GALT(group assessment of logical thinking), MTSlS(modified test of science inquiry skill), ABC-attitude scale, MSAS(modified scientific attitude scale), CSAT(common science achievement test). Structural equation modeling with LISREL VII($J\ddot{o}reskog$ & $S\ddot{o}rbom,$ 1993) was employed to estimate the causal inferences about hypothesized relationships among observed data sets. Three competing models consisted of five latent variable(scientific thinking ability, science inquiry skill, attitude towards science, scientific attitude, science achievement) - lP(inquiry preceding) model, AP(attitude preceding) model and AM(attitude mediating) model - were developed. Among these competing models, IP model satisfied the observed data sets. The causal relationships among "attitudes to science" and other latent variables were reliably identified. According to the results of the present study, science inquiry skill was the most significant variable that can predict science achievement. But scientific thinking ability has not directly influenced science achievement. This study suggests that inquiry based teaching-learning processes should be offered to students for improvement of science achievement. At the same time, it seems to be important to develop positive attitude towards science. Understanding of relationships among variables related to attitudes to science will be helpful to the development of science curriculum and to the design of science teaching and learning process. LISREL has been recognized as a useful approach in testing a SEM. However, in this study, LISREL approach was estimated as much more useful method for research design.

The importance of measurement of health-related quality of life (HRQL) cannot be overemphasized. However, efforts to implement HRQL measurement often fail because of differences in definition and insufficient information about available measures. In this paper, many available HRQL measures are reviewed, which have been designed for, or frequently used with, people with cancer in order to aid in the evaluation of effects of oriental medicine on cancer patients. A total of 28 articles were selected from three different databases. The selected articles were analyzed according to three aspects of application of the Korean version of HRQL measures, namely generic, disease specific and symptoms related instruments. Nine HRQL measures are completed with Korean validation and data collection under contact and permission of the author. However, research studies that reported data on quality of life (QOL) in cancer patients treated with oriental medicine were wholly lacking. It is recommended that further studies be performed, using methods of data collection whose validity and reliability has been confirmed.

This is descripitive study conducted to identify educational needs of mothers of nephrotic syndrome patients. The study subjects were composed of 74 mothers of nephrotic syndrome patients whose children were hospitalized in 2 Pediatric wards of University Hospital in Seoul and 1 in Pusan from June to september in 1996. A questionaire for this study was item Kikert type 5 point scale, developed on the basis of previous literature and researcher's clinical experience and the reliability of the used instruments was α=.97. t-test, and ANOVA were used to determine the effect of general characteristics of subjects on their educational needs. Pearson correlation was done to measure relations between general characterictics of subjects and their educational needs and Stepwise Multiple Regression was done to test a variable affecting educational needs. The results were as follows. 1. Mean score of the educational needs of the subjects was 137.06(Maximum 176) . The educational needs of home care was the highest score, but the question numbers are smaller than other categories. So, the educational need of the diagnosis and treatment was regarded as the highest in contents. 2. The number of subject's children, except for patient revealed significant negative correlation to educational need. 3. The number of subject's children, except for patient(R²=.215289 P=.0006)and the age of patient (R²=.23770 P=.0001) were emerged as important variables affecting the degree of mothers' educational need. Suggestion are as follows on the basis of these results. 1. It is proposed that nurses use these results of the study activly for the educational program for Nephrotic Syndrome patients and their mothers. 2. It is identified that the educational needs of the mothers of nephrotic syndrom is high. So, it is suggested to identify and analysis the degree of the nurse's educational performance perceived by mother. 3. It is suggested to make a comparative study of the degree of nurse's understanding of the importance on educational items with the instruments of this study.
