This study was prepared for the purpose of restorative consideration such as the construction background, scale, and location of buildings by comparing the historical materials of two countries, Korea and Japan, focusing on Choryanggaeksa. Choryanggaeksa was a building with a special purpose installed in Dongnaebu in the late Joseon Dynasty, and was also a space exclusively for Japanese envoys. When Choryangwaegwan, the only place of diplomacy and trade with Japan in the late Joseon Dynasty, moved in 1678, Choryanggaeksa was also built and continued until its function ceased due to the modern opening of the port. As diplomacy and trade with Japan take place in the category of Choryangwaegwan, the existence of an interpreter takes an important place. Therefore, Seongsindang, a space for interpreters, was built near Choryanggaeksa. When the modern port opened in 1876, Choryanggaeksa and Seongsindang lost their original function, but the building remained. However, after the 1890s, a Superintendent office was built on the site of Choryanggaeksa, and a school was established on the site of Seongsindang. It was destroyed when the site of Choryanggaeksa and Seongsindang was converted during the opening of the port, and its remains cannot be found today due to urbanization.

일반적으로 석회석 광산에서의 발파는 ANFO를 사용하여 주로 시행되어지고 있다. Bulk장전 시스템의 도입으로 장약, 발파가 간편하여 효과적으로 발파를 할 수 있고 그 비용도 저렴하다는 장점을 가지고 있다. 그러나 수공에서의 장약이 불가능하고 낮은 위력으로 인해 저항선 및 공간격의 제한이 커서 이에 따르는 발파효율의 저하가 불가피 하였다. 본 연구는 현재 해외에서 일반화되어 사용되고 있는 Bulk EMX(HiMEX)폭약을 국내 현장에 적용함으로 그 적용 방법과 이점을 규명하고자 시행되었다. 대규모 석회석 광산을 대상으로 적정 패턴을 산출하기 위해 기존의 발파 패턴과 비교하여 시험발파를 시행하여 저항선 및 공간격을 산정 하였으며 이를 토대로 해서 성신양회, 현대시멘트 영월사업소와 함께 장기간 시험발파를 실시하고 그 자료를 검증하였다. 그 결과 HiMEX는 초유폭약에 비해 비중이 높아 공당 장약량은 45%정도 증가하나, 1발파 당 생산 물량이 증가하여 5%이상의 장약량 감소효과를 볼 수 있었다. 또한 35∼50%정도의 천공비용이 감소되는 것으로 나타났다.

The present study examined whether individuals would respond differently, as a function of cultural self-orientations, when their requests were rejected. Also examined was whether individuals with different cultural self-orientations would predict differently how their interaction partner would respond when they rejected his or her request. Furthermore, it was investigated whether experimentally induced perspective-taking would influence responses to rejection and predictions of responses to rejection. It was found that responses to rejection as well as predictions of responses to rejection varied as a function of individual's independent self-orientation and perspective-taking. However, no significant effects were found with regard to interdependent self-orientation. Based on these results, the implications that cultural self-orientations have for request rejection and social behavior in general are discussed, and future directions are suggested.

This study has examined the physicochemical properties of the Pleurotus eryngii, including their proximate components, amount mineral content, total dietary fiber, total sugar, reducing sugar and free sugar. Additionally, it measured the P. egii ethanol extracts and the total amounts of polyphenol compounds as well as its electron donating ability (EDA) of the substance fraction (SF). The P. eryngii powder's moisture content was 9.0% and each of the other element content such as carbohydrate, crude protein, crude ash and crude fat was found to be 63.06%, 20.70%, 5.20% and 2.0% respectively. Potassium (K) was shown to be the greatest inorganic content and manganese (Mn) was the lowest. Furthermore fructose, galactose, glucose lactose and maltose free sugar content was found in this order. 387 mg% of the total amounts of polyphenol was found in the P. eryngii whole body ethanol extract, 158 mg% in the stipe extract, 593 mg% in the pileus extract and 607 mg% in the substance fraction (SF). Electron donating ability (EDA) was highest at 91.12% in the whole body extract and lowest at 62.90% in the stipe extract. Additionally, the EDA for substance fraction (SF) 0.02%-0.1% was found to be 57.78-77.33%, which was lower than the 0.02%-tocopherol (93.92%) and BHT (96.72%). From these results, it can be assumed that P. eryngii offers superior antioxidative effects with its high content of fiber, inorganic materials and total amounts of polyphenol as well as high electron donating ability (EDA), thereby making it ideal for use in functional foods and industrial materials.

The concept of "adaptability to heavy nitrogen" of rice plant was reconsidered in view of productivity with Jinheung (leading local variety) and IR667 (semi tropical variety) under the field condition. The results are as follows; 1. IR667 had higher yield and leaf area index at high nitrogen level than Jinheung. 2. IR667 increased more panicles, spikelets, filled grain ratio and grain weight by increasing nitrogen. 3. IR667 showed higher productive efficiency of grain and leaf area per unit nitrogen. 4. IR667 was higher in the productive efficiency of grain per unit leaf area. 5. IR667 appeared as panicle and spikelet number type and Jinheung as grain weight type according to yield components. 6. These results indicate that IR667 has greater productive adaptability to heavy nitrogen under the field condition.

Problem-Based Learning (PBL) is a student-centered pedagogy that integrates nursing knowledge, skills, and attitudes into clinical nursing practice. This pilot aims to apply a PBL module on preschoolers' growth and development in the nursing curriculum. This quantitative study was performed to develop a PBL module following Dick and Carye's program development process (planning, development, application, and evaluation phases), and to evaluate its effects using structured questionnaires among sophomore nursing students. These students formed teams of four or five people each and spent 40 minutes participating in the PBL module. Data were analyzed using descriptive statistics, t-tests, and content analysis. Metacognition level increased significantly. There was no significant difference in team efficacy between pre-test and post-test. Post-test learning satisfaction was high. Students reported obtaining knowledge and problem-solving ability with respect to preschoolers' growth and development and were satisfied with teamwork. This finding offers fundamental knowledge concerning the application of a PBL module in nursing curricula.

In the steel industry, there is a perception that "collusion has become a long-standing practice" and it is expected that the authorities' legal response to collusion will be strengthened in the future. This necessarily requires improving the accuracy of the legal response, the most important of which is to accurately identify whether the allegedly colluding firms actually did collude. This study focuses on the recent iron scrap price-fixing case and examines whether a single accused firm actually engaged in price-fixing in a situation where there is a mix of firms that acted independently of the collusion and firms that actually engaged in price-fixing. The results of the analysis allow us to infer that the accused steelmaker did not actually collude, which is consistent with the authorities' final judgment against the steelmaker. In the real world, some collusions are carried out by only a subset of firms in a market, and in these cases, there are often disputed firms as to whether or not they carried out the collusion. This study can serve as an analytic guide for industries, including the steel industry, to verify the behavior of individual firms, especially those whose collusive practices are disputed.

The laws and regulations governing the operation of government committees in Korea provide for a system called exclusion. Exclusion is a system that excludes a member of a committee from deliberating or voting on a matter or agenda without having to go through a special procedure before deliberating or voting on the matter or agenda. This is because exclusion of a member from deliberation and voting is not only essential for the protection of the interests of the parties to the issue or matter and the peaceful resolution of disputes, but is also a very important value for the trust in the fairness of the process. However, in practice, it is not easy to determine that a member who has a reason for disqualification is naturally incapable of executing the duties of the matter or agenda just because he or she has a reason for disqualification. Prior to the overhaul of the disqualification rules for committee members in the statutes, it is necessary to eliminate the disqualification rules that are virtually dead in advance or to revise the rules that are difficult to determine without interpretation, contrary to the intention of the disqualification rules that are codified in the law. Therefore, this study analyzed the disqualification rules of nine committees in the domestic statutes (laws and enforcement regulations) and categorized the disqualification rules. We hope to contribute to the preparation of future legislative proposals to improve the rules on the exclusion of commissioner.

This study aimed to look for educational ways to prepare for the future society for education and people of talent who will lead the post-COVID-19 era. To this end, the factors necessary for the type of future talent in the post-COVID-19 era were identified by analyzing Big data. Based on the deducted factors composing the type of talent in the post-COVID-19 era, policy direction according to the emergence of the post-COVID-19 era were deducted through the interviews with the group of experts and delphi survey, and on the basis of this, this study sought for"a plan for the educational change in line with cultivation of people of talent in the post-COVID-19 era. The results of this study are as follows. First, through the big data analytics and analysis of the interviews, convergence, ICT utilization ability, creativity, self-regulated competency and leadership were found to be the factors necessary for the type of talent in the post-COVID-19 era. Second, it considered the innovation of digital education system and the support for vulnerable classes as the issue for cultivation of people of talent in the post-COVID-19 era. Third, the most important policy with regard to the educational direction for cultivation of people of talent in the post-COVID-19 era was cultivation of convergence talents. Convergence is a very important variable in the post-COVID-19 era since it creates new values by connecting things that are separated from each other. Hopefully, this study will build a basis for competency development, education and training in preparation for the post-COVID-19 era.
