Good faith is difficult to define due to the facts that there is not an objective and concrete concept of good faith, and good faith in contracts for the international sale of goods is a principle that parties to the contract must act with sincerity as members of a social community. The Korean Supreme Court shall pay attention to setting the applicable standards that can be universally applied to good faith based on the self-established criteria. Through such effort, it is possible not only to realize the value of concrete validity pursued by the general clause of good faith but also to realize the value of legal stability by assuring the predictability of results when applying good faith. In the modern sense, it can be said that the arbitrary application of general rules rather than the escape and general clauses is a problematic situation in the application of good faith, but this problem can be solved by setting a reasonable standard of good faith. This paper studies good faith in the view of Korean law, international laws, and related cases in contract law. The purpose of this paper is to find the problems and solutions of the practical application of good faith by analyzing the Korean case (2009Da86000), which undermined the legal stability of good faith in Korea.

This study investigated university students' perspectives on good class and instructional practices through social network analysis. The subjects were 321 students in the third and fourth academic years in a Korean university. The subjects completed four open-ended questions, asking about experience of good class, good instructors' teaching practice, and their feelings and attitudes when participating in good class. As social network analysis, KrKwic (Korea Key Words in Context) was used to compute word frequencies and analyze semantic network structures and Ucinet Netdraw to assess centrality in the social network, consisting of degree centrality, closeness centrality, and between centrality. The results are as follows. First, students showed 5 keywords to depict what good class is, including 'understanding', 'example', 'video', 'interest', and 'communication'. Second, the characteristics of teaching methods by professors who practice good class indicate 'assignments', 'questions', 'understanding', 'example', and 'feedback'. Third, the top 5 keywords of students' attitudes as participating in good class are 'active', 'participation', 'focus', 'listening', and 'asking'. Last, keywords depicting desirable class that students most wanted to take next time are 'assignments', 'rewards', 'understanding', 'difficulty', and 'interest'. The findings from this study include the meanings of the semantic network structures of words in the text making up messages. Also this study can provide empirical evidence for educators and educational practitioners in higher education to create effective learning environments.

P. V$\acute{a}$mos called a ring R 2-good if every element is the sum of two units. The ring of all $n{\times}n$ matrices over an elementary divisor ring is 2-good. A (right) self-injective von Neumann regular ring is 2-good provided it has no 2-torsion. Some of the earlier results known to us about 2-good rings (although nobody so called at those times) were due to Ehrlich, Henriksen, Fisher, Snider, Rapharl and Badawi. We continue in this paper the study of 2-good rings by several authors. We give some examples of 2-good rings and their related properties. In particular, it is shown that if R is an exchange ring with Artinian primitive factors and 2 is a unit in R, then R is 2-good. We also investigate various kinds of extensions of 2-good rings, including the polynomial extension, Nagata extension and Dorroh extension.

This research aims to examine (1) the effect of carbon emission disclosure on firm value, (2) the effect of good corporate governance on firm value, (3) the mediating role of financial performance between carbon emission disclosure and firm value, and (4) the mediating role of financial performance between good corporate governance and firm value. The research sample includes 43 mining, agro, and manufacturing firms listed in the Indonesian Stock Exchange over the 2015-2017 period. Carbon emission disclosure is measured by an indicator of the Global Reporting Initiative Series of Environmental Aspect. Good corporate governance is measured by the corporate governance score of shareholder rights, boards of directors, outside directors, audit committee and internal auditor, and disclosure to investors. Financial performance is measured by return on assets, while firm value is measured by Tobin's Q. Data analysis uses the structural equation modeling. The result shows carbon emission disclosure and good corporate governance have no direct effect on firm value. On the other hand, financial performance mediates the effect of carbon emission disclosure and good corporate governance on firm value. It shows that higher carbon emission disclosure and good corporate governance are meaningless for the investor if they do not give any financial performance improvement.

The purpose of this study was to explore the component factors on images of good elementary teacher. 579 elementary teachers in Busan were sampled to be surveyed. The subjects answered open-ended questionnaire related to characteristics of good teacher. The number of items obtained from the questionnaire is 79. The exploratory factor analysis was applied to the data. As a result of exploratory factor analysis, the components of good teacher are classified into five factors : fairness, enthusiasm, commitment, warmth, self-management. All such factors might be related to the personality in common. It shows that teachers think the personality important as a characteristic of good teacher. On the basis of this result we offer a suggestion to the teacher education.

This study examines the relationship between entrepreneurship of the state civil apparatus variable and public empowerment variable in Central Kalimantan province. Samples were taken using judgment sampling techniques. Based on these criteria, it is known that only 332 regional organizational structures that meet the criteria. Thus, the sample size is 332 regional organizational structure. In each organizational structure of the regional apparatus, 3 people were selected from the state civil apparatus and 3 from the community. Also, this study considers the effect of good governance and the quality of public services as mediating variables. The analysis used in this study is PLS using WarpPLS software. the variables studied were entrepreneurship of the state civil apparatus, good governance, public service quality and public empowerment. The results of the study stated that there is a significant positive relationship between entrepreneurship and public empowerment. In addition, there is a positive effect of entrepreneurship on good governance and public service quality. also, there is a positive influence of good governance and public service quality on public empowerment. The novelty of this research is the entrepreneurship of the state civil apparatus which is the driving force of public empowerment through good governance and public service quality.

Purpose: This purpose of this study was to identify both good teaching and desirable teaching behaviors perceived by nursing students. Methods: A cross-sectional descriptive design was used. A convenience sample of 324 nursing students was selected and they completed self-reported questionnaires from November 1 to December 30, 2015. Results: Among 4 perspectives of good teaching (traditional, systemic, interaction, and constructionism), the traditional perspective was perceived as the highest form of good teaching, while the systemic perspective was perceived as the lowest. Meanwhile, disclosure and clarity were perceived as the highest desirable teaching behaviors. Regardless of students' perspective of good teaching, all 4 perspectives of good teaching were positively related with clarity, enthusiasm, interaction, organization, and disclosure as desirable teaching behaviors independently. Conclusions: Nursing students perceived that the highest perspective of good teaching was the traditional perspective. Meanwhile, they perceived that clarity, enthusiasm, interaction, organization, and disclosure were desirable teaching behaviors regardless of their perspective of good teaching. Further study will be needed to perceive nursing faculty's awareness of good teaching and desirable teaching behaviors to identify the difference of awareness between nursing students and faculty.

Objective: Endovascular thrombectomy (EVT) fails in approximately 20% of anterior circulation large vessel occlusion (AC-LVO). Nonetheless, the factors that affect clinical outcomes of non-recanalized AC-LVO despite EVT are less studied. The purpose of this study was to identify the factors affecting clinical outcomes in non-recanalized AC-LVO patients despite EVT. Materials and Methods: This was a retrospective analysis of clinical and imaging data from 136 consecutive patients who demonstrated recanalization failure (modified thrombolysis in cerebral ischemia [mTICI], 0-2a) despite EVT for AC-LVO. Data were collected in prospectively maintained registries at 16 stroke centers. Collateral status was categorized into good or poor based on the CT angiogram, and the mTICI was categorized as 0-1 or 2a on the final angiogram. Patients with good (modified Rankin Scale [mRS], 0-2) and poor outcomes (mRS, 3-6) were compared in multivariate analysis to evaluate the factors associated with a good outcome. Results: Thirty-five patients (25.7%) had good outcomes. The good outcome group was younger (odds ratio [OR], 0.962; 95% confidence interval [CI], 0.932-0.992; p = 0.015), had a lower incidence of hypertension (OR, 0.380; 95% CI, 0.173-0.839; p = 0.017) and distal internal carotid artery involvement (OR, 0.149; 95% CI, 0.043-0.520; p = 0.003), lower initial National Institute of Health Stroke Scale (NIHSS) (OR, 0.789; 95% CI, 0.713-0.873; p < 0.001) and good collateral status (OR, 13.818; 95% CI, 3.971-48.090; p < 0.001). In multivariate analysis, the initial NIHSS (OR, 0.760; 95% CI, 0.638-0.905; p = 0.002), good collateral status (OR, 14.130; 95% CI, 2.264-88.212; p = 0.005) and mTICI 2a recanalization (OR, 5.636; 95% CI, 1.216-26.119; p = 0.027) remained as independent factors with good outcome in non-recanalized patients. Conclusion: Baseline NIHSS score, good collateral status, and mTICI 2a recanalization remained independently associated with clinical outcome in non-recanalized patients. mTICI 2a recanalization would benefit patients with good collaterals in non-recanalized AC-LVO patients despite EVT.
