This study was implemented to amass and analyze the data from 500 Seoul district beauty shop workers, which came from the use of the SPSS18.0. The statistical analysis was conducted through frequency for demographic characteristics, validity for factors analysis by using Varimax rotation, and reliability for Cronbach's alpha coefficient.. Also, the analysis was once again analyzed through the Pearson correlation coefficient, where our hypothesis was proven through regression analysis. Our research results have shown that, first, job satisfaction and job performance differed over matters like gender, age, education level, employment conditions, job category, overall work experience, daily work hours, and monthly income. Second, job satisfaction was shown to have a significant influence on job performance, where higher job satisfaction levels led to higher job performance. Thus, job satisfaction was a great factor to increase job performance by fulfilling their needs level. Also, they would act more positive and future-oriented when they have special needs like motivate achievement, wage, promotion, and reward. Therefore, managerial staff should continually develop any programs in order to upgrade beautician's job performance through their job satisfaction.

Recently, the industrialized world is suffering from accidents referring from the lack of safety consciousness. According to Korean Safety Regulation Department(1996), students at junior high schools are mostly involved in safety accidents, and this is due to lack of safety consciousness. To prevent these accidents, we need to have safety consciousness and attitude. To make junior high school students who are mostly affected in these accidents act safely, they need to know their level of safety consciousness. The purpose of this study is to develop a guideline of measuring the scale of safety consciousness and analyze the relationship between safety education, accident experiences and safety consciousness. This study is based on a survey of 708 junior high students in Seoul, which was carried out from 12 November, 2001 to 21 November, 2001. 1. The main fields of safety consciousness are home safety, school safety, fire safety, emergency management based on documents. Home safety is again divided into facility safety and livelihood safety, school safety is divided into facility safety, livelihood safety and laboratory safety, traffic safety is divided into pedestrian safety, bicycling safety and public transportation safety, fire safety divided into prevention and escaping during fire breakouts, emergency management safety is divided into general principles and escaping during emergency situations. 2. The primary safety consciousness scale was made according to every field of safety consciousness. A preliminary examination based on the scale and a study of reliance and the factors was held. Based on these results, 27 questions which were concerned to be impairing reliability or lacking in factor were deleted on the secondary safety consciousness scale development The secondary safety consciousness scale which constituted of 73 questions was put into another preliminary study and after analyzing reliability and the factors, 12 questions of low reliabilities were deleted and with these results, the third scale were made consisting of 61 questions. 3. A study based on the third safety scale which is made of 61 questions, were held and with a analysis of the reliability and factors made, the relationship between safety education, accident experience and safety mind were examined. (1) The study of reliability and factors show that Cronbach's coefficient in home safety fields is .7598, in school safety .7924, in traffic safety .8306, in emergency treatment .7775, in fire safety .7247. The questions indicating low reliability were deleted. The factor analysis revealed that home safety is converged on facility safety and livelihood safety. But one question was deleted because it showed incongruence of validity. School safety was converged on facility safety, livelihood safety and laboratory safety. But 2 questions showed incongruence of validity and these were deleted. Traffic safety fields were converged on pedestrian safety, bicycle safety and public transportation safety. One question showing incongruence of validity was deleted. Emergency treatment fields converged on general principles and acting in emergency situations and three questions showing incongruence of validity were deleted. Fire safety was converged on prevention and acting in fire breakouts. Totally, eight questions were removed and the final scale were consisted of 53 questions (2) The 3/sup rd/ grade students scored higher average safety mind scales than 1st graders(p〈.05). And students who had high scores at school tend to have a higher scale than those who do not(p〈.001). (3) Average scale of students who had experience in safety education were higher(p〈.001). Students who had previously been involved in home safety accidents had a low score(p〈.001). This was same to students with experience in school safety accidents(p〈.001). Students with traffic safety accidents and fire safety accidents tend to have a lower scale too(p〈.05, p〈.001).

Purpose: The 2020 Dietary Reference Intakes for Koreans (KDRIs) serves as a foundation for daily nutrient and energy recommendations aiming to enhance public health and prevent chronic diseases. They act as guidelines for maintaining proper nutrition and overall health. Using KDRIs is crucial for promoting healthier lifestyles and making informed dietary choices. Thus, this study explores the influence of a nutrition education program, based on the 2020 KDRIs, on the nutrition knowledge and dietary habits of undergraduates in Gyeongsangnam-do and Gyeonggi-do. Methods: The nutrition education program, designed with diverse instructional materials, was executed across a wide range of universities. The education group (n = 75) engaged in the program for a 6-week instructional period, while the control group (n = 53) underwent the survey without participating in the education program. Nutrition Quotient (NQ) and knowledge assessments were administered to both groups immediately before and after the instructional period. Results: Within the education group, the nutrition education program positively impacted responses to NQ practice items, including knowledge of nutrition, daily intake, and portion sizes (p < 0.05). In contrast, there were no significant differences between the before and after responses of the control group for most survey items. Post-program evaluations showed significantly higher self-assessment scores and increased satisfaction levels (p < 0.05), with the satisfaction rate for the education program using the 2020 KDRIs reaching 99.2%. Conclusion: This study has demonstrated the positive impact of an effective nutrition education program. However, there is a need for the continuous development and implementation of nutrition education programs to sustain these outcomes and further enhance the nutritional education experience.

Recently, various investigation of vegetable oil which is extracted from natural resources is being progressed because of its low cost and environmental aspect. However, double bonds in vegetable oil should be substituted to other high reactive functional group due to its low reactivity for synthesizing bio-polymeric materials. ${\alpha}$-eleostearic acid, which is consist of conjugated triene, is the main component of tung oil, and the conjugated triene allows tung oil to have higher reactivity than other vegetable oil. In this study, tung oil is copolymerized with styrene and divinylbenzene to make thermoset resin without any substitution of functional group. Thermal and mechanical properties are measured to investigate the effects of the composition of each monomer on the synthesized thermoset resin. The result shows that the products have only one Tg, which means the synthesized thermoset resins are homogeneous in molecular level. Mechanical properties show that tung oil act as soft segment in the copolymer and make more elastic product. On the other hand, divinylbenzene acts as hard segment and makes more brittle product.

The water circulation in agricultural watersheds changes with the operation of agricultural reservoirs, it is necessary to classify and evaluate them into upstream, agricultural reservoirs, irrigation districts, and downstream. Therefore, in this study, we developed the agricultural water circulation rate (AWCR) considering an agricultural reservoir and irrigation district by improving the water circulation rate of the Water environmental conservation Act. we applied it to Jinwi watershed using the module-based hydrologic analysis system to simulate the water circulation for agricultural reservoirs and irrigation areas. The model performance during the validation period was NSE of 0.762 for the downstream stream and 0.682 for the reservoir level. And the hydrograph separation model was applied to separate the direct and baseflow. As a result of this study, The AWCR of Jinwi watershed was 71.8% on average, which was higher than the water circulation rate estimated by the downstream hydrograph separation.

Due to the COVID-19 pandemic, scholars at institutions of higher education around the world are transitioning their teaching, service, and research into online settings; for many this may be a new and challenging experience. While many of the best practices associated with research in traditional or face-to-face settings also apply to research in or via online settings, there are some additional challenges and nuances that researchers must adequately address and plan for due to the affordances and limitations of online settings. This paper discusses the key issues of privacy, informed consent, trust and trustworthiness, and retention through the literature and provides practical recommendations based on evidence and experience from two different online research projects. The reflections on and examples from these two research projects contextualize the above issues and act as evidence to inform research as a practice. The authors hope this evidence and practical guidance may help researchers better prepare for research in a socially distanced world.

The aim of this study is to clarify what influence has on elementary school children's environmental awareness in time of teaching environmental problems from an animistic viewpoint and from non-animistic viewpoint. For this purpose, this study carried out its research targeting 126 students in fourth grade at M elementary school located in U Metropolitan City. This study suggested the environmental problems by re-edifying the already suggested environmental problems from an animistic viewpoint to 62 students for two classes which were classified as an experimental group after sampling 10 cases of the representative environmental problems that might derive from the earth system, and conducted the class on 10 main topics relevant to the problematic situation of environment with an animistic viewpoint excluded targeting the remaining 64 students forming a comparison group. The results of this study were as follows: First, there appeared an ex-ante ex-post statistically significant difference in the awareness of environmental problems from the experimental group which received an environmental class from an animistic viewpoint. However, there didn't appear a statistically significant difference from the comparison group. This study interprets this result to mean that elementary students' awareness of environmental problems increase because they think about the environmental problems by associating them with a problem of life when the students receive the environmental class from an animistic viewpoint. Second, there appeared an ex-ante ex-post statistically significant difference in the awareness of environmental problems from the experimental group which received an environmental class from an animistic viewpoint. However, there didn't appear a statistically significant difference from the comparison group. Regarding this aspect, this study believes that the experimental group shows much higher willingness to environmental act in comparison with the comparison group because elementary school students think of inanimate objects as living things.

Health institutions in Korea include a wide range of traditions, most notable of which are hospitals, clinics, pharmacies and health centers as foci for the dispension of western medicine care ; and herb clinics and shamans acting as centers for traditional medicine. Health consumers have pluralistic conceptions of illness(or disease) and act accordingly, using what they consider as appropriate medical practices. The research conducted surveyed residents of Jeomdong-Myon(a rural farming district), Guro 6-Dong(an urban district) and the Banwol(a semiurban district) area on attitudes about health institutions and their utilization of them. The results indicate that the hospital is considered the most reliable health institution, however, the most widely known and commonly used institution was the pharmacy. Hospitals and clinics were found to be utilized more frequently by those residents who were familiar with them than by others less familiar with them. In addition respondents with higher education, those with medical insurance, and those living in urban areas tended to utilize hospitals and clinics more frequently than their less educated, uninsured, or rural counterparts. Converse to the ranking of western medical institutions, traditional health institutions were rated low with regards to reliability, familiarity and utilization. This indicates that western medical care has pervaded the Korean medical system.

Polyurethanes containing mesogen unit (MPU-6) were prepared from 4,4'-diphenylmethane diisocyanate (MDI) and 4,4'-bis(6-hydroxy hexoxy)biphenyl (BP-6) having flexible chain composed of 6 carbons. Intrinsic viscosities of MPU-6s were in the range of $0.23{\sim}0.56 dL/g$. The mesomorphic behaviors of MPU-6 were observed in X-ray and polarizing microscopy analysis. However, MPU-6s demonstrated a 'virtual liquid crystal' behavior, which did not exhibit mesophase on slow heating and slow cooling. MPU-6 having lower molecular weight exhibited higher crystallization rate and melting crystallization temperature due to increased mobility of polymer chains. The increased mobility of polymer chains facilitate the orientation of mesogen units that may act as a nucleating agent.
