The protection of fundamental rights of people is a natural duty of a state. Since Constitutional Law declare that a state is obliged to protect the fundamental rights of people obviously, it is reasonable to postulate that a state has a duty to protect every person's right much more positively. Of course, it is true that whereas right of freedom is much more important in modern states, the social right becomes more important currently. Nevertheless, we have no choice but to put an emphasis on the importance of the right of freedom like modern states. Thus states are still bound to try to protect the right of people, specific duty of behavior for the sake of right of freedom belongs to states. In particular, due to the fact that lifts are essential to our comfortable life and the demage from the accident concerning with the lifts is fatal, the strategy for securing the safety of using the lifts is significant to some extent. And because it is true that the experience of UK that put an emphasis on the role of civil actors is meaningful to us, there seems implications for us. Accordingly, it is possible to consider the material components such as the check of safety before installation for the sake of safety enhancement, quality control for lifts parts, specification of check criterion and variation of check cycle etc. and personal ones such as specification of qualification of competent persons, guarantee of competent person's independence, variation of obligator's duty and variation of user's obligation etc. However, as the situation of UK is one thing and that of Korea is another, we don't have to adhere to the policy and the experience of UK strictly. Rather, we had better apply the policy and experience of UK to ours appropriately.

This essay is a landscape of core values and relevant evidences about Creative Leadership in order to make sketches of Korean-style leadership framework. Glancing through this work, you can smell the distinctions of Korea creative leaders, particularly, in the aspects of procommunity pragmatism and ordinary innovation. Most Korea creative leaders were social mentors and masters who had enlarged their influences from the individual domain to social area in all the dimensions of human life. At the individual stage, the Creative Leadership suggests 'Jungki(正己)' as a core value of themselves, which is materialized as such competencies as self-assertiveness, observation and experimentation, and strong inquiry. Because most of them were technical masters dealing with new methodology and new knowledge including alchemy, medicine and weapons, the creative leaders show us very unique core values and competencies in the life sequences of the individuation, relationship, organization and community unlike other Korean-style leaderships and global practices. You can taste and compare these things: 'Kihyulsangtong(氣血相通)' as a core value and respect- for- others, style analysis, persuasion as core competencies in the stage of relationship, nextly, 'Suhshi(授時) & Jungeum(正音)' as a core value and coordination and adjustment, teamwork as core competencies in the stage of organization, finally, 'Hunmin(訓民) & Hwalin(活人)' as a core value and vision-building, social benefiting, ordinary innovation as core competencies in the stage of community. The value of this study is focused on the construction of Korean-style leadership framework based on the Creative Leadership through vivid stories about great leaders in our history.

The effect of carbon addition on the microstructures and mechanical properties of $Ni_3Al$ and TiAl intermetallic alloys have been characterized. It is shown that carbon is not only an efficient solid solution strengthener in $Ni_3Al$ and TiAl, it is also an efficient precipitation strengthener by fine dispersion of carbide. Transmission electron microscope investigation has been performed on the particle-dislocation interactions in $Ni_3Al$ and TiAl intermetallics containing various types of fine precipitates. In an $L1_2$-ordered $Ni_3Al$ alloy with 4 mol.% of chromium and 0.2~3.0 mol.% of carbon, fine octahedral precipitates of $M_{23}C_6$ type carbide, which has the cube-cube orientation relationship with the matrix, appear during aging. Typical Orowan loops are formed in $Ni_3Al$ containing fine dispersions of $M_{23}C_6$ particles. In the L10-ordered TiAl containing 0.1~2.0 mol.% carbon, TEM observations revealed that needle-like precipitates, which lie only in one direction parallel to the [001] axis of the $L1_0$ matrix, appear in the matrix and preferentially at dislocations. Selected area electron diffraction (SAED) patterns analyses have shown that the needle-shaped precipitate is $Ti_3AlC$ of perovskite type. The orientation relationship between the $Ti_3AlC$ and the $L1_0$ matrix is found to be $(001)_{Ti3AlC}//(001)_{L10\;matrix}$ and $[010]_{Ti3AlC}//[010]_{L10\;matrix}$. By aging at higher temperatures or for longer period at 1073 K, plate-like precipitates of $Ti_2AlC$ with a hexagonal structure are formed on the {111} planes of the $L1_0$ matrix. The orientation relationship between the $(0001)_{Ti2AlC}//(111)_{L10\;matrix}$ is and $[1120]_{Ti2AlC}//[101]_{L10\;matrix}$. High temperature strength of TiAl increases appreciably by the precipitation of fine carbide. Dislocations bypass the carbide needles at further higher temperatures.

Honeybees (Apis mellifera) are common pollinators and important insects studied in agriculture, ecology and basic research. Recently, RDA (Rural Development Administration) and YIRI (Yecheon-gun Industrial Insect Research Institute) have been breeding a triple crossbred honey bee named Jangwon, which have the ability to produce superior quality honey. In this study, we identified a single nucleotide polymorphism (SNP) marker in the genome of Jangwon honeybee, particularly, in the paternal line (D line). Initially, we performed Sequence-Based Genotyping (SBG) using the Illumina Hiseq 2500 in 5 honeybee inbred lines; A, C, D, E, and F; and obtained 1,029 SNPs. Seventeen SNPs for each inbred line were generated and selected after further filtering of the SNP dataset. The 17 SNP markers validated by performing TaqMan probe-based real-time PCR and genotyping analysis was conducted. Genotyping analysis of the 5 honeybee inbred lines and one hybrid line, $D{\times}F$, revealed that one set of SNP marker, AmD9, precisely discriminated the inbred line D from the others. Our results suggest that the identified SNP marker, AmD9, is successful in distinguishing the inbred honeybee lines D, and can be directly used for genotyping and breeding applications.

Objective: Effects of linseed oil (LO) supplementation on the fat content and fatty acid profile of breast meat, and the expression of three genes in the liver, breast muscle and fat tissues of commercial 154-day-old hybrid male turkeys were investigated. Methods: The animals in the control group were fed a commercially available feed and received no LO supplementation (n = 70), whereas animals in the LO group (n = 70) were fed the same basic diet supplemented with LO (day 15 to 21, 0.5%; day 22 to 112, 1%). The effect of dietary LO supplementation on fatty acid composition of breast muscle was examined by gas chromatography, and the expression of fatty acid desaturase 2 (FADS2), peroxisome proliferator activated receptor gamma (PPARγ), and insulin-like growth factor 1 (IGF1) genes was analysed by means of quantitative reverse transcription polymerase chain reaction. Results: The LO supplementation affected the fatty acid composition of breast muscle. Hepatic FADS2 levels were considerably lower (p<0.001), while adipose tissue expression was higher (p<0.05) in the control compared to the LO group. The PPARγ expression was lower (p<0.05), whereas IGF1 was higher (p<0.05) in the fat of control animals. There were no significant (p>0.05) differences in FADS2, PPARγ, and IGF1 gene expressions of breast muscle; however, omega-6/omega-3 ratio of breast muscle substantially decreased (p<0.001) in the LO group compared to control. Conclusion: Fatty acid composition of breast meat was positively influenced by LO supplementation without deterioration of fattening parameters. Remarkably, increased FADS2 expression in the liver of LO supplemented animals was associated with a significantly decreased omega-6/omega-3 ratio, providing a potentially healthier meat product for human consumption. Increased PPARγ expression in fat tissue of the LO group was not associated with fat content of muscle, whereas a decreased IGF1 expression in fat tissue was associated with a trend of decreasing fat content in muscle of the experimental LO group.

The pandemic age came to us after the COVID19 broke out in the early of 2020, which resulted in many changes in our everyday life. One of the changes is non-contact transactions in economic activities, especially contact-free financial transactions are ever-increasing activities in the pandemic age. In non-contact financial transactions, security and trust are important issues that users are concerned about the most. So the paper examines how security and trust have effects on the attitudes of bank customers who use mobile banking applications on their smartphones. The study conducted factor ananlysis to extract research constructs using survey data gathered during Nobember of 2020 through February of 2021 across the nation. After extracting the constructs, the study checked validity, sampling adequacy, and internal reliability with KMO, Bartlett's test, and Crombach Alpha respectively. To make sure the purpose of the study, I do regression analysis. All factors of attitude had impacts on willingness on both of transactions and purchasing financial products. The results could give guidelines banks which want to attract more customers in open-banking environment through ever-more secure and trusty mobile banking application.

Psychological properties of learners have influence on learning behaviors in various ways. The purpose of this study was to examine how the goal orientation of learners affected the learning time distribution method. Regulatory focus and theories of intelligence were measured and manipulated in order to differentiate participants' goal-oriented state. Two variables are known to be key variables influencing learner's goal orientation, inducing the approach-avoidance strategy and mastery-performance oriented attitude. In the experiment, the control focus was divided into two groups based on the inclination test score (regulatory Focus Questionnaire, RFQ), and TOI(theory of intelligence) was temporally induced through manipulation to confirm the interaction between the two variables. Participants were able to determine the order of learning freely by learning a set of Spanish-Korean word pairs and then selecting the items they would like to re-learn. Word pairs consisted of difficult or easy items, and learners could learn the same word many times if they wanted to. In the results, promotion-incremental group showed allocating difficult word-pairs in early time.

The purpose of this descriptive correlational study was to explore the effect of knowledge of evidence-based practice (K-EBP) and organizational culture on the innovation behavior of university librarians in South Korea. The structured survey questionnaire consisted of four sections and 60 items. The four sections were concerned with K-EBP, organizational culture, innovation behavior, and EBP-related activities and demographic. The respondents were librarians working in 101 university libraries in South Korea. The results of this study were as follows. First, K-EBP indicated that the respondents had excellent practical skills, but their ability to appraise critically, apply knowledge and to conduct research was weak. Second, the questionnaire scores for K-EBP were significantly positively correlated with those for organizational culture and innovation behavior. Higher K-EBP scores corresponded to higher scores for relation-, innovation-, and task-oriented organizational culture. Third, K-EBP outcomes differed significantly by age group, education level, employment type, job title/seniority, reading of academic journal articles, and attendance at conferences. Organizational culture differed significantly with age. Innovation differed significantly with both age and conference attendance. Fourth, in the hierarchical multiple regression analysis, factors predicting K-EBP scores were education level and reading academic journals. Fifth, the multiple regression analysis identifying factors predicting innovation revealed statistically significant regression coefficients for overall K-EBP and for innovation- and hierarchy-oriented organizational culture. The regression coefficient for perception of a hierarchy-oriented organizational culture was negative. To promote innovation behavior of librarians, we need to foster an innovative organizational culture characterized by communication and cooperation, and improve the ability of librarians to engage in EBP. Educational programs that promote librarian engagement in research-related activities are needed.

While welcoming the distributing of the powers of the Ministry of Education, which is currently being promoted, to the city and provincial offices of education, I am very concerned that this will expand and amplify the powers concentrated in one central institution to 17 local institutions closer to the field. Until now, the Ministry of Education and the Office of Education have served as co-cause providers as important reasons for hindering school education. The transfer of the authority of the Ministry of Education is highly likely to be deformed as soon as it results in the quantitative reduction of the functions and roles of the existing Ministry of Education and the quantitative expansion of the roles and functions of the city and provincial offices of education. In the reality that no legal device for school autonomy has been established, it is highly likely that emphasizing the principle of school autonomy in our educational climate, which is deeply rooted in the vertical bureaucratic administrative culture, will end with a simple measure or stop at the level of imitation. Therefore, a more stable device is needed to check the authority of the city and provincial office of education and the superintendent of education to take over the authority of the Ministry of Education. This is also a system that is still required even when school autonomy becomes legal. Therefore, it is necessary to revitalize the independent education committee, establish a local education committee in the city and province education office, and activate the resident participation system (resident proposal system, resident voting system, resident litigation system, resident audit request system).

The Mongolian lingonberry and blueberry are two essential food sources found in Mongolia. This study investigated the antioxidant and anti-inflammatory effects of methanol extracts from Mongolian lingonberry (LBE) and blueberry (BBE). Compared to the LBE, the BBE showed higher total phenolic, flavonoid, and anthocyanin contents, as well as antioxidant capacities. The LBE and BBE inhibited the mRNA expression of pro-inflammatory genes, including tumor necrosis factor-α (TNF-α), interleukin-1β (IL-1β), and cyclooxygenase (COX-2) in lipopolysaccharide-stimulated RAW 264.7 macrophage cells. In addition, the LBE and BBE inhibited NADPH oxidase-2 (Nox2) mRNA expression, indicating that they have cellular antioxidant capacities. Anthocyanin derivatives of the LBE and BBE were analyzed using LC-QTOF/MS. Six anthocyanins were identified in the BBE, while one was detected in the LBE. Our findings demonstrate that the anthocyanin-rich LBE and BBE could be used as functional food sources in Mongolia.
