We furnished some properties of fuzzy testing of independence for correlation in a bivariate normal distribution by agreement index. First we present some restriction of the fuzzy data, define fuzzy sample correlation coefficient and agreement index for testing hypothesis with acceptance or rejection degree. Also, we show that UMP unbiased fuzzy test and drawing conclusions the fuzzy test.

XML/EDI는 데이터 전달에 초점을 둔 전통적인 EDI의 범위를 확대하여 전자상거래에 필요한 프레임워크(framework)를 제공한다는 면에서 전통적인 EDI와 정의가 다르다. 기존의 EDI 서비스를 인터넷 플랫폼으로 옮겨가고 다시 Web 플랫폼으로 옮겨감으로써 EDI 서비스 사용자들은 기존의 서로 다른 EDI 전용 소프트웨어의 사용에 따른 불편함이 없어지고 통합된 환경으로 EDI 서비스를 사용할 수 있다. 본 논문에서는 이러한 전자상거래 시스템의 핵심 요소인 웹 기반 XML/EDI시스템의 전체적인 설계 및 구현에 대해서 기술한다. 기술된 XML/EDI 시스템은 현재 80% 정도의 구현정도를 보이고 있으며, 웹을 통한 시연이 가능하다.

3D 콘텐츠에 대한 관심이 증가함에 따라 3D 시청 및 제작에 대한 가이드라인의 필요성도 함께 증가하고 있다. 3D 안정 시청 가이드 라인은 3D 시청으로 인한 시청자의 시각적 불쾌감이나 피로감을 방지하는데 목적을 두고 있으며, 최근 일본의 3DC에서는 과도한 수렴-조절 불일치를 방지하기 위해 양안 시차 $1^{\circ}$를 쾌적 시차 범위로 권고하고 있다. 하지만 이 쾌적 시차는 절대적인 수치가 아니며, 콘텐츠의 특성 및 시청 조건에 따라 변하는 것으로 추정된다. 본 논문에서는 쾌적 시차를 갖는 3D 영상 콘텐츠에서 객체의 모션으로 인해 양안시차가 시공간적으로 변할 때, 야기되는 시각적 불편함의 변화에 대하여 관찰한다. 특히, 깊이 방향 모션 및 수평 방향 모션에서 객체의 속도 변화에 대한 시각적 피로감의 정도를 주관적 평가를 통하여 측정한다.

The purpose of this study is to examine hospital noise level and discomfort due to noise. The subjects were 156 patients from University hospital in Taegu. The data was collected from April 10 to May 14, 1997. The collected data were analyzed by SPSS program using percentage, paired t-test, ANOVA, and Pearson Correlation Coefficient. The results were as follows ; The mean score of noise level was 1.62. There was no statistically significant difference in noise level between day and night. Patients perceived higher noise in the categories of conversation of visitors, conversation of care providers, noise of air conditioners, and the conversation of nearby patients than others during the day. Patients perceived higher noise in the categories of noise of air conditioners, conversation of visitors, conversation of care providers, and telephone ringing than others during the night. There were no statistically significant differences in noise level among the 4 wards during the day or night. Discomfort was due to the forementioned noise, categories of high scores were sleep disturbed, irritated, not so bad or not noisy, and noisy. To avoid noise, the subjects coped by putting on a quilt, going out, sleeping, opening or closing the window or door, and plugging ears. These results indicated that hospital noise have a negative influence on patients' health. So noise levels should be reduced in hospitals.

The purpose of this study is to evaluate for effective eye care service to the aged population of rural community. The results was as follow. 1. The aged who were using aids such as glasesses or had difficulties in everyday life without aids account for 66%. 2. The case of having some difficulties in everyday life and not using glasesses was 68persons(28.8%). 3. as for the reason why not using visual aids, 40.7% responded that they were able to see well without it and 31.4% could not have for burden of cost though in need of it.

In this paper, to provide a binaural beat in the method of treatment of sleep disorders. Let the sound of different frequencies, the waveform of the brain resonate at a specific frequency, to induce a stable state, is converted over to a high-frequency audio frequency, improves the listening experience. To target the three college students for the results performance evaluation of, conducted an experiment on the sense of stability at the time of sleep, in the process, the brain waves were measured as a means to check the degree of sense of stability.

Often there are edentulous patients with severe vertical resorption of the alveolar ridge so that implant placement in the mandibular posterior is impossible. In this case, implants can be placed in the anterior portion of the mandible and the patient can be treated with an implant assisted overdenture, but the inherent discomfort of the removable prosthesis can not be overcome. However, if implants are appropriately placed between the mental foramen of both sides and a fixed hybrid prosthesis is fabricated to the patient, the patient will be satisfied without the inconvenience of the removable prosthesis. However, the treatment plan should be well designed to prevent disadvantages and expected complications of fixed hybrid prosthesis. Based on my clinical experience, I will explain treatment plan and protocol in detail.

It is crucial that the WRMSD is realized as a critical job-related diseases for the construction workers. It is caused by the characteristics of repetitive work, uncomfortable work methods and continuous unsuitable physical posture. The objective of this research is to evaluate the workload for the carpenters and structural steel workers. Investigation on the posture and behavior for the workers as well as personal sensitivity to the workload is conducted. The laboratory tests with graduate students are conducted to estimate inconvenience in terms of personal sensitivity to the workload. The results of this research will be used to perform the further researches on ergonomic and technological approaches to improvements of the hand-intensive tasks in the construction industry.

This study classifies the types of urban railway stations that reflect the location characteristics of urban railway stations, the structure and form of station taxes, and the number of users, and the level of inconvenience in the transfer movement line for users by station type, the number and connectivity of transfer information, and the level of transfer convenience facilities. The number of installations, conflicts between users, and transfer information signs were analyzed. As a result of data analysis, it was found that the factors that cause the most inconvenience to urban rail users when transferring are the length and curvature of the transfer line, pedestrian density and number of passengers in the transfer passage, presence or absence of transportation convenience facilities, and the size and height of transfer information letters. These transfer inconveniences were objectified, quantified, and presented as evaluation indicators that can measure the transfer convenience of urban railway stations. Additionally, an evaluation scale was developed to measure the service level for each evaluation indicator. The evaluation scale for each indicator presented six levels by applying linear interpolation based on the maximum and minimum values of data derived through field surveys. However, it is judged that a comprehensive evaluation of transfer convenience that combines the importance and weight of each convenience evaluation indicator should be established through future research.

This study is a descriptive study to identify the patterns of use of menstrual sanitary products among community women of childbearing age. The participants were 1,571 women between the ages of 19 and 40, and data collection was conducted through online and mobile surveys from September 2020 to August 2021. As a result, 88.9% of the participants were using disposable menstrual pad, 5.6% tampons, 3.1% cloth menstrual pad, and followed by others(2.4%), including menstrual cups. The differences of type of menstrual sanitary products according to general characteristics showed significant in age(p=.006), marital status(p=.005), education level(p=.002), annual salary(p=.018), experience of pregnancy(p=.036), and menstrual regularity(p=.022). More than half of the participants(53.8%) responded that cloth menstrual pads were 'very safe' or 'safe,' but 27.9% and 20.1% of disposable menstrual pads and tampons, respectively. The difference in menstrual distress according to the type of menstrual sanitary products showed that tampon users had a higher menstrual discomfort score for the most recent menstruation(F=4.092, p=.017) and 4 days before menstruation(F=4.178, p=.016) than users of disposable menstrual pad or cloth menstrual pad. Therefore, it is necessary to continuously investigate the use of menstrual sanitary products by women of childbearing age and its relationship with reproductive health.
