Sharehouse has been supplied as an alternative to solving the steadily increasing one-room housing problem of single-person households every year, and it is necessary to investigate the satisfaction of residents who actually live in sharehouse through P.O.E. Therefore, this study analyzed priror researches related to the existing one-person households, sharehouses, and satisfaction surveys, and summarized indicators with high relevance and frequency to derive satisfaction survey factors that can clearly evaluate the improvement architectural plan of sharehouses. As a result, it was classified into 4 items in the 'general information' category to investigate the status, housing rental type, and housing cost of the sharehouse, 15 factors in the 'peripheral environment' category to evaluate the safety, 3 factors in the 'community' category, and 17 factors in the space (facility) and service category. In the "General Information" section, the overall one-person housing satisfaction, desired sharehouse type, housing rental type, housing cost, and living expenses were reduced. In the "Surrounding Environment", accessibility to public office, accessibility to cultural facilities, accessibility to medical facilities, accessibility to work and school, convenience stores, noise pollution and safety. In addition, in the "community" section, it consists of interactions with various people, relationships with housemates and in the "space (facilities) and service" section, heating, waterproof, soundproof, ventilation, moisture and condensation blocking, facility management, interior, room size, built-in furniture, storage space, laundry, parking. Most of the scales for each factor were 5-point Likert scales, allowing evaluation of the degree of satisfaction, and some factors presented criteria to induce structured answers. Therfore, it is expected that the survey will be conducted on residents who actually live by deriving factors for the satisfaction survey of one-person households living in the sharehouse, and the current status of the sharehouse will be identified, and the degree of satisfaction will be analyzed to be used for research.

Amongst varieties of clinical nursing role, the administration of medication is often highlighted as of prime importance. In order to attain data for the improvement of teaching strategies of medication, diagnostic evaluation of the knowledge level is a necessity. This study was performed from August through December 1975. 449 registered nurses, randomly sampled from general hospitals:16 of Seoul and 7 of Taegu and Pusan, were tested through 54 test questionaries based on 4 practical dimensions of administration of medication. Results are as follows ; 1. Status of respondents: Length of clinical experiences; the average length revealed to be 2 years and 7 months, 72% revealed to have had less than 3 years of experience; 38.6%-less than 1 year, 19 .2%-over 1 year and less than 2 years, and 14, 2%-over 2 years and less than 3 years. Type of Nursing education received ; 9.4% revealed to have graduated technical high school of nursing, 67.5o/o the 3 year diploma school and 21, 7% the baccalaureate degree program. The knowledge Level; Degree of self-satisfaction on knowledge level revealed that;27, 4% responded to "more or less satisfied", 48.8% "more or less un-satisfied" and 19.8% to "not satisfied". The average level of basic knowledge revealed to be moderate by 66.95 points. The level of knowledge of 4 questionnaire categories revealed that; drug action category by average of 66.5 points, methodology category by 65.4 Points, safety measure category by 71.4 points and terminology and concepts category by 64.6 points, Questionnaire items which revealed high points are of;6 of drug action category, 4 of methodology, 4 of safety measure, and 3 of terminology. The items of low points are: 8 of drug action, 3 of methodology, 3 of safety measure and 5 of terminolology categories. 3. The type of nursing education revealed to have no significant influence on the level of knowledge on the administration of medication. 4. The length of clinical experience revealed to have no significant influence on the level of knowledge. 5. 75. l% responded that the actual practice of medication modes are "similar" to that included in the fundamentals of nursing course. 6. In-service education on medication; 54.0% revealed to have some incidental in-service education on medication while 34.0% receive programmed in- service education. 61.8% revealed to have expressed the need of systemic In-service education as one of the means for improvement of medication. 32.7% revealed to obtain information concerning medicine by reading commercial publications on drug package, while only 20.9% by reading specific information channel.

Electrical product safety certification is for public safety. Korea electrical safety certification (KC) is being tested and certified on the base of Korean electrical appliance safety act and KC scheme. There are operating system and Electrical safety standards in the KC scheme. KC' operating system was adapted from japan operating system of Japan certification scheme. But KC certification' electrical safety standard was adapted from IEC standards of IECEE CB scheme. So There are many problems such as difference of version between KC standards and IEC standards, discrepancy between operating system and standards. Therefore, This paper analyzed the reason of discrepancy and proposed the improved KC certification operating system in order to reduce cost and to save time in the procedure of issuing KC approval for public safety in using electrical products and also for global competence.

Drought monitoring over paddy field area is an important role as the frequency and intensity of drought due to climate change increases. This study analyzed the applicability of drought monitoring on paddy crops using MODIS-based field surveys. As a satellite-based drought index using evapotranspiration for quantitative drought determination, ESI (Evaporative Stress Index), was applied and calculated through the ratio of MODIS- based actual and potential evapotranspiration. For the irrigated areas of Idong, Gosam, Geumgwang, and Madun reservoirs the availability of irrigation water supply, ponding depth, precipitation, paddy growth were investigated for the paddy field within one grid of MODIS. In addition, the percentile-based ESI drought severity was calculated to compare the growth process of paddy and changes in the drought category of ESI. The Idong area was irrigated about a week later than other reservoirs for the period of water supply, transplanting, and water drainage and the ESI drought category tended to be different. The Gosam, Geumgwang, and Madun area expressed moderate drought prior to the farming season, and indicated normal as the water was supplied. During the water drainage, the drought category intensified, indicating that the water available on land was decreasing. These results demonstrated that the MODIS-based ESI could be an effective tool for agricultural drought monitoring over paddy field area.

Objective: The Job Demand & Resources model suggests work characteristics are related to mental well-being and work engagement. Previous work describes the development of a combined construct 'engaged well-being at work' (EWB). To what extent changes in measures of this construct are responsive to changes in job demands and resources or associated with changes in job-related attitudes has not been established. Methods: Longitudinal employee-level data from three waves (German Linked Personnel Panel) were used. Logistic and linear fixed effects regression analyses explored longitudinal associations between changes in EWB for participants over a three-year period with changes in job demands and resources and job-related attitudes (job commitment, satisfaction, and turnover intentions). Results: While job resources were associated with increased odds for a change into a healthier and/or more engaged category of EWB, job demands reduced them. Job resources were more strongly related to higher EWB (OR_range = 1.22 - 1.61) than job demands (OR_range = 0.79 - 0.96). Especially psychological job demands showed negative associations with improved EWB (OR = 0.79). A change from the least desirable category 'disengaged strain' to any other category of EWB was associated with greater odds by up to 20.6 % for increased commitment and job satisfaction and lower odds for turnover intentions. Discussion: Improving work characteristics, especially job resources, could increase employees' EWB, emphasizing the importance of job characteristics for a healthy workplace. Because EWB seems to be associated with job attitudes, an improvement of this indicator would be relevant for employees and employers.

Background: This study aimed to identify the validity of breast cancer symptom questionnaire of worker's special health examination and its relationship with breast ultrasonography findings in young female night workers. Methods: The breast cancer symptom questionnaire data of worker's special health examination and breast ultrasonography results in young female shift workers who worked in one electronic manufacture company were collected from 2014 to 2018. Results: Of the 857 workers, 18 had a Breast Imaging Reporting and Database System category 4 or higher. Among other variables, shift work tenure alone was associated with the risk of having a Breast Imaging Reporting and Database System category higher than 4. The sensitivity, specificity, positive predictive value, and negative predictive value of the symptom questionnaire were 16.7%, 87.7%, 2.8%, and 98.0%, respectively. Conclusion: The current breast cancer symptom questionnaire of the worker's special health examination is inappropriate due to its low sensitivity and positive predictive value. In the future, female night workers will need alternative measures for more accurate screening for breast cancer.

The purposes of the study were to identify knowledge and skill levels required for effective nutrition teachers and to compare perceived need and dietitians' self-evaluation of the knowledge and skills. A total of 60 knowledge statements and 70 skill statements associated with 11 job functional areas were specified through a literature review and expert panel reviews. A total of 457 dietitians working at school foodservices in Seoul and Gyeonggi province were surveyed using a self-administrated questionnaire and 148 responses were returned. Excluding responses with significant missing data, 142 responses were used for data analysis. In terms of knowledge, 'sanitation, food safety and employee safety(4.60)' category received the highest perceived need score, followed by 'nutrition education(4.56)' and 'nutrition counseling(4.45).' The knowledge category that received the highest self-evaluation was 'nutrition and menu management(3.66)' while the category that received the lowest self-evaluation was 'teaching practices(2.83).' In terms of skills, the highest perceived need was associated with 'nutrition education(4.49)', followed by 'sanitation, food safety and employee safety(4.46)' and 'nutrition counseling(4.39).' The dietitians rated their skills related to 'sanitation, food safety and employee safety(3.67)' the highest but their skills related to 'teaching practices(2.84)' the lowest. The dietitians' self-evaluated knowledge and skill scores were significantly lower than their perceived need of the knowledge and skills in all job functional areas(p<0.001). A quadratic analysis based on the requirement and self-evaluation of the knowledge and skills revealed that priorities of the education programs targeting school nutrition teachers or students preparing to be a nutrition teacher should be placed on improving knowledge and skills related to nutrition education, nutrition counseling, teaching practices, sanitation and employee safety, and nutrition and menu management. Educational programs for nutrition teachers should be designed to decrease the gaps between the need and self-evaluation of the knowledge and skills for effective nutrition teachers. The findings of the study can be used to develop education materials for nutrition teachers. The knowledge and skills identified in the study should be updated and revised regularly to reflect changes in regulations and current practices in school foodservice programs.

Technology status was investigated by analyzing patents and development cases of wearable robots. Development direction of wearable robot for wearability was also suggested by understanding the problems of wearability from development cases through the FGI technique. The number of patents per technical field was the most in the field of strength support, but AI in the technology field was different in each country; Korea was found to be poor in the category of daily living assistance. The number of patents by technology category was the most in the category of muscular strength assistance. However, the values of AI in the technology category were different in each country; Korea was found to be poor in the category of daily living assistance. Development cases were focused on rehabilitation, so development is not fulfilled uniformly by use purpose. By wearing body parts, robots with single function type were mainly developed. Rigid material robots were mainly developed. It was confirmed that wearable robot technology is not developed evenly in the category of application because it is in the early stage of the technical proposal and centered on main performance improvement. We derived twelve wearable conditions for wearable robots: Shape and Size Appropriateness, Movement Appropriateness, Composition Appropriateness, Physiological Appropriateness, Performance Satisfaction, Ease of Operation, Safety, Durability, Ease of Dressing, Ease of Cleaning, Portability and Ease of Storage and Appearance Satisfaction. Finally, the development direction of a wearable robot for each wearable condition was suggested.
