Purpose: The purpose of this study is to identify the educational needs of a severe trauma treatment simulation program based on mixed reality which combines element of both virtual reality and augmented reality. Methods: Focus group interviews were conducted with ten military hospital nurses on February 4 and 5, 2021. The collected data were analyzed using a qualitative content analysis. As a framework for data analysis, the educational needs were clustered into the following four categories: teaching contents, teaching methods, teaching evaluation, and teaching environment. Results: The educational needs for each category that emerged were as follows: three subcategories including "realistic education reflecting actual clinical practice" and "motivating education" for teaching contents; five subcategories including "team-based education," "repeated education that acts as embodied learning," and "stepwise education" for teaching methods; six subcategories including "debriefing through video conferences," "team evaluation and evaluator in charge of the team," "combination of knowledge and practice evaluation" for teaching evaluation; six subcategories including "securing safety," "similar settings to real clinical environments," "securing of convenience and accessibility for learners," and "operating as continuing education" for teaching environment. Conclusion: The findings of this study can provide a guide for the development and operation of a severe trauma treatment simulation program based on mixed reality. Moreover, it suggests that research to identify the educational needs of various learners should be conducted.

In order to explore feeding practices of large ruminants and methods followed in the rural areas, an exploratory survey was made during the period from January 1988 to January 1989 in eight different agro-ecological areas of Bangladesh in relation to the existing seasons and farmers' categories. The study shows what feeding practices varied (p<0.01) from area to area and season to season but not with the farmers' category. Considering the overall picture of feeding practices existing in the country, it can be observed that bigger proportion of farmers practiced stall feeding and tethering ($38.4{\pm}35.1$) followed by stall fed ($34.3{\pm}35.2$) and grazing or tethering ($17.3{\pm}26.7$). The figure with wider deviations indicates that farmers in the rural areas did not follow a smooth feeding practice, the system is rather a complex, heterogenous and a mere consequence of existing land use system. The results of feeding methods of by-product concentrates indicate that it also varied (p<0.01) from area to area but however, not with seasons and farmers' category. It is observed that bigger proportion of farmers fed concentrates to their animals mixed with water ($74.1{\pm}30.3$) followed by mixed with roughage and water ($10.3{\pm}13.3$) or fed alone ($5.6{\pm}14.2$). The method like feeding practice is also complex and heterogenous in the rural areas of Bangladesh. Hence, it is needed to develop a strategic feeding system and method identifying the problems associated with those.

설문조사를 실시할 때 응답자가 설문조사의 일부 문항에 대하여 응답하지 않는 경우 항목무응답이 발생한다. 무응답이 발생한 자료를 제외하고 완전하게 응답된 자료 만에 근거한 분석은 분석 결과에 편의가 발생할 수 있으므로, 이를 채워 넣어 완전한 형태의 자료로 분석하기 위해서 무응답 대체가 흔히 사용되고 있으며 여러 가지 무응답 대체 기법들을 비교하는 연구들도 많이 존재한다. 패널조사 연구는 연구 대상 패널에 대하여 정해진 시간에 따라 반복적으로 동일한 설문 문항에 대하여 응답을 조사하여 시간에 따른 변화를 살펴보는 조사 방법을 나타낸다. 패널조사 자료의 항목 무응답을 대체할 때 이전 시점의 응답 자료가 존재한다면 이를 포함하여 대체를 실시하는 것이 바람직한 것으로 여겨져 왔으나 이에 관한 직접적인 연구는 찾기 힘들다. 따라서 본 연구에서는 패널자료에서 이전 시점의 정보를 고려하지 않고 대체를 실시하는 방법과 이전 시점의 정보를 활용하여 대체하는 방법들 중에서 어느 대체 방법이 보다 적절한 대체를 제공하는지 살펴보았다. 특히 이전 시점의 응답 정보를 이용하는 방법인 비대체, 선형혼합모형을 이용한 대체와 선형혼합모형에 근거한 베이지안 대체 방법을 고려하였고, 이를 이전 시점의 정보를 고려하지 않는 대체 방법들 중 흔히 사용되는 평균대체, 핫덱대체 방법과 비교하였다. 모의실험 결과 선형혼합모형에 근거한 베이지 안 대체 방법이 다른 대체 방법에 비해 무응답 비율이 높아지더라도 편의도 작으며 평균에 관한 95% 신뢰구간의 포함률도 높게 나타나서 가장 좋은 대체 방법으로 확인되었다.

This retrospective descriptive study was done to identify maternal characteristics related to infant feeding methods. Data were collected by self-report from 90 mothers who visited a health clinic in Seoul between July 30 and August 14, 2001. The mothers were classified into 3 groups according to the feeding method at 4 weeks after childbirth; Exclusive breast feeding group, Mixed breast feeding group, Bottle feeding group. Mothers using exclusive breast feeding accounted for 46.6% of the mothers, those using mixed breast feeding, 26.7%, and those using bottle feeding, 26.7%. Although the percentage of mothers using exclusive breast feeding was higher, there was no significant difference among the groups. In our research, characteristics related to the mother were found to be in a state of change. Mothers with higher education and having a job had higher rates for exclusive breast feeding. This result is different from that of earlier research. Further research is needed to confirm these characteristics. In order to increase the rate for exclusive breast feeding and the duration of breast feeding, nurses need to provide programs aimed at fostering breast feeding and these programs should be based on characteristics related to breast feeding shown in our research.

In this study, 16 antibiotics were selected from among the top 30 veterinary antibiotics sold in South Korea in 2014, as well as from among the pharmaceuticals targeted by EPA method 1694, in order to review analytical methods for the detection of trace levels of antibiotics in environmental samples: surface water, soils, animal origin foods, and manures. LC-MS/MS was heavily used. In the chromatography for the detection of the selected antibiotics, the $C_{18}$ column was mostly used at the temperature of $30{\sim}40^{\circ}C$. Water and methanol/acetonitrile were commonly chosen as a nonpolar and a polar mobile phase, respectively. Gradient elution was applied to separate multiclass antibiotics. Volatile additives, such as formic acid, acetic acid, and ammonium acetate were mixed with the mobile phase to improve the ionization efficiency of analytes and the sensitivity in MS detection. Electrospray ionization (ESI) was widely used in the LC-MS/MS and positive ionization was preferred to determine the selected antibiotics. A protonated $[M+H]^+$ molecule was selected as a precursor ion, and its two transitions were analyzed, one for quantitative measurement and the other for confirmation. This study reviewed linearity of the calibration curve, recovery, repeatability, method detection limits (MDLs), and method quantification limits (MQLs) for each target compound used to validate the developed analytical methods.

Objectives: This study was conducted to evaluate efficacy and safety of Punica granatum L. Actinidia chinensis Planch. mixed extract on body fat. Methods: Thirty women were recruited ($25kg/m^2{\leq}body$ mass index [BMI]${\leq}29.9kg/m^2$) ($19yr{\leq}age{\leq}38yr$) and randomized to receive Punica granatum L. Actinidia chinensis Planch. mixed extract or placebo for 8 weeks. During the test, they visited four times including screening. Body fat mass, body fat rate, anthropometric dimensions at waist and hip, waist-hip ratio, total cholesterol, triglyceride, low density lipoprotein-cholesterol (LDL-C), and high density lipoprotein-cholesterol (HDL-C) were measured at screening and 8 weeks after screening. Adverse reaction were also checked each visit. Results: There were no significant differences in all index. But when divide experimental group by BMI index, age, and compliance, less than BMI $27kg/m^2$ group decreased body weight, body fat mass and more than BMI $27kg/m^2$ group also decreased body weight, body fat mass and waist circumference. Less than age 30 years group showed decline of waist circumference, fat free rate and T-cholesterol and more than age 30 years group showed decline of fat free mass. Group with compliance more than 95% was decreased BMI, fat free mass, and hip circumference. Conclusions: There was no significant efficacy as compared with placebo group, but as divide experimental group according to BMI index, age, compliance, mixed extract might be effective to reduce obesity index.
