The study was conducted to assess sanitary concepts of employees and needs of HACCP-based sanitation training program for elementary school foodservice operations. Subjects consisted of 370 foodservice employees. Foodservice employees' demographic characteristics were surveyed, and their food sanitation knowledge was tested. Food sanitation knowledge included 4 dimensions of foodborne disease & food microbiology; sanitary management in food product flows; personal hygiene management; and equipment & facility sanitation management. The data were analysed using the SPSS package for descriptive analysis, t-test and ANOVA test. The average sanitation knowledge score was 9.5 out of 15. The working periods of foodservice employees were singnificantly(p<01) related to food sanitation knowledge dimensions. Correct answering rate of 4 sanitation management dimensions were 74.4% in foodborne disease & food microbiology; 536% in sanitary management in food product flows; 78.7% in personal hygiene management; and 50.5% in equipment & facility sanitation management. 6 items in 4 sanitation knowledge dimensions under mean score were identified. Those items were temperature danger zone, thawing method of frozen foods, cooking & holding temperature, proper sampling & storage methods, proper storing methods in refrigerator, and proper washing & sanitizing method for utensils. Identified 6 items were included in 12 critical control points developed for the elementary school generic HACCP plan, and should be emphasized in implementing HACCP-based sanitation training program.

To know the role of 'the solid compressive pressure to the first solid layer of a cake, $p_d$' in the 'unified theory on solid-liquid separation', we analyzed extremely compressible cake formed with floc for the following three operations with our new concepts. First, the role of $p_d$ was studied in calculating the sediment thickness of floc, and in calculating the cake thickness in cake filtration performed with floc sediment. Second, we calculated the expression procedure using $p_d$. Finally, the influence of $p_d$ on cake thickness in hindered sedimentation, and on the calculation of the procedure of hindered sedimentation $p_d$ was verified. Thus the possibility of application of 'unified theory on solid-liquid separation' and the importance of $p_d$ was verified. Through these processes, new theoretical definitions of the cake filtration, expression and hindered sedimentation was established.

This is a methodological study to develop standards for human body coordinate clinical terminology system. The Standard was developed through four stages: Stage 1 - research plan was developed through literature review and data collection. Stage 2 - preliminary standard was created. Stage 3 - the standard was revised in accordance with the consultation of experts through seminars. Stage 4 - Final version of the standard was presented after verification of the content level. 2D human body images are expressed as x, y axes, and 3D images are expressed as x, y, z axes. Concepts and definitions of coordinates were preassembled into FSN, synonyms and preferred names of SNOMED CT. The latter combination was defined through 18 relationships. The average index was 4.01 for the content validity of the developed relationship standard. This research suggests that subsequent standards should be developed for other parts of the human body such as the brain, organs, and tissues. Also, it suggests that methodological research should be continued to increase the utilization of the standard in clinical practice.

Background: Medically unexplained symptoms (MUSs) are common in primary care. Atpresent, there are no proven, comprehensive treatments available in primary care forpatients with MUSs. However, MUS has parallels with "subhealth" or Mibyeong from tradi-tional East-Asian medicine, and thus, Mibyeong interventions could be effective in treatingMUS. Unfortunately, studies on Mibyeong and its intervention methods are relatively rare.Methods: We administered a web-based survey to 17,279 Korean medicine (KM) practitionersregistered with the Association of Korean Medicine. The response rate was 4.9% (n = 849).Based on the responses received, we assessed how much they agreed with concepts relatedto Mibyeong on a 7-point scale from "do not agree" to "strongly agree." Respondents werealso asked to indicate how frequently they encountered various subtypes and patterns ofMibyeong, and how frequently they use listed intervention methods.Results: Data from 818 respondents were analyzed after excluding those with no clinicalexperience. On average, respondents were male general practitioners aged between 30 yearsand 49 years, working or living in metropolitan areas such as Seoul, Incheon, and Gyeonggi-do. Responses did not differ by demographics. Respondents generally thought that Mibyeongreferred to subjective or borderline findings without certain disease, and that Mibyeong hasvarious subtypes and patterns. Subtypes included fatigue, pain, and digestion problems; pat-terns were either deficiencies (e.g., qi, blood, and yin deficiency) or stagnations (e.g., liver qidepression and qi stagnation). Decoction was the most frequently used type of interventionfor Mibyeong of all items listed, followed by acupuncture and moxibustion. Patient educa-tion was also recommended, suggesting healthy eating, promoting healthy environment,and exercise.Conclusion: We were able to provide preliminary results on KM practitioners' recognition ofand interventions for Mibyeong, but further research is needed to develop a detailed defi-nition of Mibyeong and its myriad subtypes and patterns, and evaluations of the efficacy ofMibyeong interventions.

In this study, the students' responses on the chemistry items of in the general science of College Scholastics Ability Test (CSAT) implemented for the past 3 years since 1999 were investigated. The number of items by content and inquiry process, the average percent correct by content and inquiry process, the distribution of items by the level of percent correct, and the items with high and/or low percent correct were analysed. There were the fewest items in 'environment' area, especially in 'ozon layer', no test item had been made. The most difficult content area was 'acid rain' in 'environment'. By inquiry process, the most number of items belonged to 'analyzing & interpreting data', and 'identifying problems & formulating hypothesis' was the most difficult process. No test item came under the level of 'very difficult', and many items under the 'easy' or 'very easy' level. Students were generally poor at solving test items demanding several concepts, and very good at simply requiring basic concept treated in lower grade. Educational implications are discussed.

The coronavirus disease 2019 (COVID-19) pandemic, which has been rampant since the end of 2019, has evidently affected pain management in clinical practice. Fortunately, a COVID-19 vaccination program is currently in progress worldwide. There is an ongoing discussion that pain management using steroid injections can decrease COVID-19 vaccine efficacy, although currently there is no direct evidence to support this statement. As such, the feeling of pain in patients is doubled in addition to the co-existing ill-effects of social isolation associated with the pandemic. Thus, in the COVID-19 era, it has become necessary that physicians be able to provide high quality pain management without negatively impacting COVID-19 vaccine efficacy. Steroids can alter the entire process involved in the generation of adaptive immunity after vaccination. The period of hypophysis-pituitary-adrenal axis suppression is known to be 1 to 4 weeks after steroid injection, and although the exact timing for peak efficacy of COVID-19 vaccines is slightly different for each vaccine, the average is approximately 2 weeks. It is suggested to avoid steroid injections for a total of 4 weeks (1 week before and after the two vaccine doses) for the double-shot vaccines, and for 2 weeks in total (1 week before and after vaccination) for a single-shot vaccine. This review focuses on the basic concepts of the various COVID-19 vaccines, the effect of steroid injections on vaccine efficacy, and suggestions regarding an appropriate interval between the administration of steroid injections and the COVID-19 vaccine.

This study is aimed at examining the employment preparation of Chinese migrant women and exploring measures to support their employment in a practical manner. To accomplish the objectives, in-depth interviews with 15 Han Chinese and Korean Chinese women, who represent the highest proportion in Korea, were conducted. Each interview lasted for about an hour and a half on average, and there were additional questionnaires and observations on vocational courses. Collected data was analyzed in 4 steps by utilizing the analysis methods suggested by Lichtman (the three C's of data analysis: codes, categories, concepts), which were transformed to fit the final data. The research findings are as follows. First, the fundamental reasons that Chinese migrant women seek employment in Korea are as follows: role model as a mother based on motherhood and the desire to be recognized as a member of society. Second, as for employment strategies, although all the respondents were only dependent on the referral of their acquaintances and national institutions, Han Chinese and Korean Chinese women had ambivalent attitudes toward each other. Third, they attributed the causes of unemployment to personal aspects such as the amount of effort made and luck, and social structural aspects, including employment instability and low acceptance of multi- cultural individuals. Fourth, the migrant women hoping for 'complete integration' in the future, suggested some practical employment support measures. Such measures should be established by comprehensively reflecting their reasons for getting a job, employment strategies, attributions of unemployment, and employment outlook, rather than as response measures to the low birth rate and aging issues in Korea.

Research reactors for radioisotope production, fuel and material testing and research activities are designed, constructed and operated based on the society's needs. In this study, neutronic and thermal hydraulic design of a high neutron flux research reactor core for radioisotope production is presented. Main parameters including core excess reactivity, reactivity variations, power and flux distribution during the cycle, axial and radial power peaking factors (PPF), Pu₂₃₉ production and minimum DNBR are calculated by nuclear deterministic codes. Core calculations performed by deterministic codes are validated with Monte Carlo code. Comparison of the neutronic parameters obtained from deterministic and Monte Carlo codes indicates good agreement. Finally, subchannel analysis performed for the hot channel to evaluate the maximum fuel and clad temperatures. The results show that the average thermal neutron flux at the beginning of cycle (BOC) is 1.0811 × 10¹⁴ n/㎠-s and at the end of cycle (EOC) is 1.229 × 10¹⁴ n/㎠-s. Total Plutonium (Pu₂₃₉) production at the EOC evaluated to be 0.9487 Kg with 83.64% grade when LEU (UO₂ with 3.7% enrichment) used as fuel. This designed reactor which uses LEU fuel and has high neutron flux and low plutonium production could be used for peaceful nuclear activities based on nuclear non-proliferation treaty concepts.

The purpose of this study is to explore the meaning and essence of the learning experiences of K University students majoring in educational school librarianship. In order to achieve the purpose of the research, an open-ended question-based focus group interview was conducted for 12 major students who had graduated from K University's master's degree course within two years. By analyzing the contents of the answers, 9 themes, 35 categories, and 104 concepts were derived from the learning experience in the master's course. Looking at the main analysis results for each area, the motive for entering the master's course was to acquire a librarian teacher qualification, which is a condition in applying for the employment examination. The Satisfaction with the learning experience was an average of 7.66 out of 10 points. In addition, the most dissatisfied parts during the master's course was the contents of the subjects and classes that were not helpful in the operation of the school library and the employment examination for librarian teachers, therefore the response was that improvement is necessary for the future development of the librarian master's degree curriculum.

Personal distance is one of the basic and important concepts in the field of Environmental Psychology in influencing personal space, visible or invisible territoriality and psychological carrying capacity of contemporary urban dwellers. This study aims to analyze the bench users' behaviour and personal distances in urban parks for the first time in Korea, one of the representative landscape spaces in urban areas. For these purposes, this study has adopted a blind observation and pictorial analysis for bench users in Yeouido Park in Seoul. The main results of this study show that the average interpersonal distance between female and male(intimate relationship) is 47.5cm, the distance between female and female is 53.2cm, and the distance between male and male is 70.3cm. These results mostly support the previous western study results, but the interpersonal space and territoriality of Koreans in urban parks may be smaller than that for western societies.
