This study examines how consumer attitudes toward food origin and health concerns influence beef purchasing behavior. Using data from the Korea Rural Economic Institute's food consumption behavior survey, we analyzed the frequency of purchasing domestic and imported beef. Results indicate that when not distinguishing between domestic and imported beef, perceptions of lower origin quality and higher health concerns are associated with an increase in purchasing frequency. However, such influences are statistically insignificant for imported beef. Further analysis reveals that for consumers exclusively purchasing domestic beef, these factors do not significantly impact purchasing frequency, while for consumers simultaneously purchasing both domestic and imported beef, these factors do significantly impact purchasing frequency.

Film-induced tourism in Gyeongbuk and Korea is concentrated on the on-location set, one-off events and film tourism as part of a holiday(visiting film locations or studios as an activity within a larger holiday) among several forms of film-induced tourism. Film-induced tourism in Gyeongbuk has been increased since the opening of the KBS on-location set of Mungyeong. The on-location set has brought the growth of film-induced tourism and thus many local governments have competed with one another for the construction of the on-location set without considering the management of the on-location set. This study is aimed at suggesting ways to minimize these negative problems and to boost film-induced tourism. First of all, we should find ways to sustain each characteristic of the on-location set. Second, we should develop the new tourism destinations by diversifying the forms of film-induced tourism through the opening of the film-related events and the construction of the film-related facilities. Last, film-induced tourism should be enlarged to contents tourism. It needs to enlarge the role of the Gyeongbuk Film Commission. The Gyeongbuk Film Commission should take exclusive responsibility of developing the film-related tourism commodities.

The Changes in management environment in SMEs such as rapid development of information communication technology, worldwide expansion of FTAs, enlargement of global outsourcing, etc have changed various aspects in industry-academy or industry-academy-government cooperation. It has been away from the cooperation focused on research and development and industrial training, and advanced to the cooperation focused on the business fields and practices where the executive ability and professionalism are required to commercialize major products of local SMEs. Compared with the existing model, the new model of industry-academy-government cooperation can provide effective and customized supports to local SMEs and expect better performance than ever before through the choice and focus. However, the existing support programs of government and related organizations are just top-down pattern to SMEs. In addition to the development of industrial technology, education and training for labor force and knowledge interchange between industry and university, the new cooperation model would also provide practical tasks such as enhancement of business competences and abilities to cultivate foreign markets. This study deals with Gyeongbuk PRIDE Products support project that is the new model of industry-academy-government cooperation and evaluates the effectiveness of this support project by empirically analyzing the survey results from the target SMEs.

The purpose of this study was to explore the labor relations and job attitudes on KORAIL's employees. The subject of the study was the members of the Gyeongbuk Headquarters of Korea Railroad Corporation(KORAIL). For the purpose of analysis, a survey was conducted for 155 members of KORAIL Gyeongbuk Headquarters, and 119 questionnaires were used for the final analysis. The results of the analysis are as follows: First, there are 3 powerful parties in the KORAIL system of labor relations as Union, Management and Goverment. The KORAIL system of labor relations is very unstable and rigid. The labor union of KORAIL engaged in a desperate struggle against the management. Second, there are significant differences in job satisfaction, communication, organizational commitment, job attitudes between union members and non-union members. These results indicate that establish a labor-management community culture, communication need to be more activated. The activation of communication can contribute to building confidence in labor-management relationship.

This experiment was carried out in order to determine proper plant growth regulators (PGR) and their concentrations for direct shoot induction and somatic embryogenesis from leaf tissue cultures of Muscari armeniacum 'Early Giant'. Direct shoot formation from the leaf explant culture was effective only on a half-strength MS medium containing $0.1mg{\cdot}L^{-1}$ 2,4-D, while embryogenesis was occurred on a half-strength MS medium containing $0.1{\sim}1.0mg{\cdot}L^{-1}$ IPA or without PGR. The regenerated bulblets derived from embryos or shoots were harvested and transplanted into a greenhouse. The sprouting percentage of bulblets obtained from different culture media ranged from 80 to 100% and growth of quality bulblets was enhanced when the bulblets were harvested from the medium containing $0.1mg{\cdot}L^{-1}$ NAA and $1.0{\sim}3.0mg{\cdot}L^{-1}$ IPA.

For effective production of interspecific hybrids of Lilium and valuable new cultivars, we used Lilium Asiatic hybrid 'Tiny Ghost' as the female parent, and Oriental group, and Longiflorum group and Martagon as the male parents. Percentage pollen germination in Oriental hybrid 'Sorbonne' was the highest with 64%. As results of using normal style pollination and cut style pollination methods, all seed sets were formed in normal style pollinated treatment, except in 'Aktiva'. Pollen germination percent of Longiflorum hybrid 'Norina' was higher than that 'Gelria'. However, all crossings using 'Norina' failed to set seeds. Corresponding fertilization ratio was different from genetic compatibility, even in the same group. From the crossing using 'Aktiva' as the male parent one bulb was obtained derived from one embryo sac. And using 'Sorbonne' as the male parent, one plantlet was obtained after four ovule cultures. Crossing using 'Gelria' as the male parent five embryos, 15 embryo sacs, and seven ovules per one ovary were obtained. Among them, 18 plantlets germinated, with the germination percent of 66.7%. Crossings using L. hansonii, Martagon group, as the male parent resulted in 40% germination from five ovules.

Lithium-ion battery (LiB) with high energy density and efficiency has been utilized for the electric vehicle (EV) and energy storage system (ESS) as well as portable devices. However, as explosion accidents have frequently happened till lately, all-solid-state lithium secondary battery (ALSB) began to get in a spotlight because it can secure a very high safety and energy density by substituting flammable organic liquid electrolyte to nonflammable inorganic solid electrolyte. In spite of ALSB's certain merits, it has shown much poorer performance of cells than one of LiB due to some challenges, which have been small or never dealt with in the LiB system. Hence, although plenty of studies made progress to solve them, an approach about design of all-solid-state electrode (ASSE) has been limited on account of difficulty of ALSB's experiments. That is why the virtual 3D structure of an all-solid-state electrode has to be built and used for the prediction of cell performance. In this study, we elucidate how to form the 3D ASSE structure and what to be needed for the simulation of characteristics on ALSB. Furthermore, the ultimate orientation of 3D modeling and simulation for the study of ALSB are briefly suggested.

Purpose: A high anion gap (AG) is known to be a significant risk factor for serious acid-base imbalances and death in acute poisoning cases. The strong ion difference (SID), or strong ion gap (SIG), has recently been used to predict in-hospital mortality or acute kidney injury (AKI) in patients with systemic inflammatory response syndrome. This study presents a comprehensive acid-base analysis in order to identify the predictive value of the SIG for disease severity in severe poisoning. Methods: A cross-sectional observational study was conducted on acute poisoning patients treated in the emergency intensive care unit (ICU) between December 2015 and November 2020. Initial serum electrolytes, base deficit (BD), AG, SIG, and laboratory parameters were concurrently measured upon hospital arrival and were subsequently used along with Stewart's approach to acid-base analysis to predict AKI development and in-hospital death. The area under the receiver operating characteristic curve (AUC) and logistic regression analysis were used as statistical tests. Results: Overall, 343 patients who were treated in the intensive care unit were enrolled. The initial levels of lactate, AG, and BD were significantly higher in the AKI group (n=62). Both effective SID [SIDe] (20.3 vs. 26.4 mEq/L, p<0.001) and SIG (20.2 vs. 16.5 mEq/L, p<0.001) were significantly higher in the AKI group; however, the AUC of serum SIDe was 0.842 (95% confidence interval [CI]=0.799-0.879). Serum SIDe had a higher predictive capacity for AKI than initial creatinine (AUC=0.796, 95% CI=0.749-0.837), BD (AUC=0.761, 95% CI=0.712-0.805), and AG (AUC=0.660, 95% CI=0.607-0.711). Multivariate logistic regression analyses revealed that diabetes, lactic acidosis, high SIG, and low SIDe were significant risk factors for in-hospital mortality. Conclusion: Initial SIDe and SIG were identified as useful predictors of AKI and in-hospital mortality in intoxicated patients who were critically ill. Further research is necessary to evaluate the physiological nature of the toxicant or unmeasured anions in such patients.
