Intermediate Chinese Conversation is an elective course offered by the Department of Chinese Studies for second- and third-year students at our university. It aims to help students learn basic sentence structures and grammar, familiarize them with intermediate-level Chinese conversational expressions, and naturally engage in everyday Chinese conversations. Most class activities involve speaking, but there are difficulties, such as students being relatively passive in class and not actively presenting. Using class models presented in previous literature, the present study develops a problem design, teaching-learning activity design, process evaluation, and outcome evaluation for Intermediate Chinese Conversation. By applying this design in class, this study identifies the differences between the traditional lecture-centered method used before and the new teaching method used after four weeks. It shows that the latter method — PBL helps students learn Chinese conversation more effectively. In conclusion, this study effectively tackles two issues: First, it encourages students to adopt an active learning attitude. Students who were previously not interested in Chinese conversation classes and were left out began to take interest in the class using the PBL method. Second, it helped enhance students’ problem-solving ability. Through group activities, students collaborated with each other, reaffirmed the value of working together, and sufficiently solved the problems given to them.

우리나라 열병합 발전소에서 운영되고 있는 최신 증기터빈의 출력과 효율 향상을 위한 첫 번째 기술적인 진보는 고온, 고압의 증기를 사용할 수 있는 소재 개발의 진척이라고 할 수 있다. 소재의 발전과 더불어 증기터빈의 내부효율 향상을 위한 설계적 노력의 결실 로 높은 효율의 증기터빈이 제작되었다. 오랜 기간 운전 중인 증기터빈의 내부효율은 기계적 수명의 한계로 점차 손실이 발생하고 효율 과 출력이 떨어지게 된다. 이러한 이유로 본 연구에서는 상용프로그램을 이용하여 열병합 발전소용 고압(HP)-중압(IP) 증기터빈의 증기유 로 성능해석을 수행할 수 있는 모델을 개발하고 성능계산 방법을 제시하고자 한다. 증기터빈의 복잡한 성능계산방식으로 인해 증기터빈 실무자들에게 실질적으로 유용한 참고문헌이 될 수 있도록 주요 변수들을 제시하였다. 또한 증기터빈 성능계산에 필요한 열정산도 분석 과 증기터빈 성능계산 결과의 적합성을 성능시험 결과와 비교 확인하였다.

이 연구는 해양경찰조직의 발전을 위해 해양경찰공무원이 인식하는 권한 부여 리더십이 조직시민행동과의 관계를 검증 목적 으로 연구를 진행하였다. 리더십에는 다양한 유형이 있지만 해양경찰공무원은 직무 특성상 부여된 권한이 실무에서 더욱 효과적인 문제 해결에 도움이 될 것이며, 비록 비공식적 행동이지만 결과적으로 조직의 발전으로 연결되는 조직시민행동은 최근 조직발전과 관련된 연 구로 많이 진행된다는 점에서 접근하였다. 이 연구에서는 해양경찰공무원 168명을 대상으로 구조화된 설문지를 통해 연구가 진행되었으 며 연구 결과 해양경찰공무원의 직무는 위험성, 돌발성 등으로 인해 해양경찰공무원은 상호 의존적 직무 성격이 중요하므로 중간 관리자 의 목표에 대한 설명과 구성원에 대한 다양한 행동은 해양경찰 조직성과에 긍정적 결과로 연결된다는 점에서 정책적 제언을 하였다.

Tetracycline is one of the most commonly used antibiotics in domestic and foreign livestock industries to suppress the growth of pathogens. Tetracycline has been reported as a non-biodegradable compound. Therefore it has been not completely removed in the sewage treatment process. In this study, tetracycline was degraded using liquid ferrate (VI). Based on these experiments, the optimal water condition (pH and water temperature) were selected, appropriate liquid ferrate (VI) dosage was calculated, and finally the degradation pathway was estimated with the intermediate products detected by LC/MS/MS. All degradation experiments were completed within 30 seconds and the optimal condition was obtained in basic condition (pH 10) at room temperature (20℃). And the appropriate molar ratio between tetracycline and liquid ferrate (VI) was 12.5:1. Finally, 12 intermediate products were detected with LC/MS/MS and the degradation pathways and the degradation pathways and proposed the degradation pathways.

The revitalization of e-business via Internet brings big changes to the postal business, and leads to a tremendous increase of heavy and large sized postal mails with continuing growth of home delivery business. Thus, even though the number of intermediate storages for mail delivery that mailmen use for picking up mails in the middle of mail delivery has been being increased, it has still many problems such as insufficient number and size of the storages as well as avoidance of mail keeping of trust agents. It is necessary that safety of mail keeping, seamless mail delivery, and individual parcel pick-up process reestablish- ment should be made through an improved counter plan for the problems described previously. This study presents the efficient and right operational plan for the intermediate storage for mail delivery with providing the number and size of intermediate storages per mail delivery sequence according to four different types of post offices.

The causes of juvenile crimes are varying with many reasons, can not be just defined with one reason. It is very easy for juveniles to become violent and fall into misdeed, bad social environment; such as, family or parents' divorce problems accelerates this kind of misbehavior, especially when they are mentally acuity in this stage of their lives. On the impulse of the moment directly connects to the delinquencies which make their life miserable and furthermore, they become an obstruction of the society and country. Juvenile delinquents have to be take cared with psychological treatments, such as using a dog, because their hearts are dried up for many reasons. It is possible to help delinquents in The Chun An Juvenile Prison to reduce criminal minds and violent behaviors through psychological treatments and reform edification to make them love animals. This study has been researched through result of surveysand MMPI tests on guard diaries and observation record for using dogs as a treatment for violent reduce of juvenile delinquents in The Chun An Juvenile Prison. With the result, we came to the conclusion that it will be a suitable program for juvenile and female delinquents in the future.

The term corrections is almost idendified with punishing. Especially the term is relatively new. Prior to the 1950s, the term penal system and penology were largely commented. These term usually pointed out the punishment focus placed on those convicted of crimes. It was not until 1954 that the American Prison Association changed its name to the American Correctional Association, what reflected a basic shift in the philosophy of correcting deviant and lawbreaker. In the historical overview of corrections and the criminal justice system, society has dealt with lawbreakers in a multitude of ways and has emphasized different goals and diverse methods to accomplish those goals. On those ways, we cannot overestimate the virtue of consciousness of sin and criminal`s will of reintegrating itself into the lawabiding society. The punishment and the intermediate sanctions should be proactive and focused on the needs of criminals and society itself. Crimianl should and can be changed to go back into the stream of society through awakening the consciousness of criminal culpability of convicted and inspiring wilfulness of being lawabiding citizens. The most appropriate way of corrections is based upon theoretical consideration, how society view criminals, how society treat criminals.

Trades are classified as a direct trade, in which an exporter and an importer directly conclude a contract to execute a transaction, and an indirect trade, in which a transaction is conducted through a third party. A license issued by NSSC is required for the indirect trade of Trigger List Items although the items do not cross the Korea’s borders. This study would summarize characteristics for each type of the indirect trade, and suggest things considered from the perspective of regulations. Sensitive items such as weapons of mass destruction could be illegally transferred through black trade, and the role of brokers is important. Therefore, Korea controls indirect trade of Trigger List Items in a more conservative approach, although NSG guidelines does not include it as a control scope. Advanced countries in export control field such as the US, UK, and Canada also controls on indirect trade. One of the indirect trade types is an intermediate trade in which the goods are imported from a foreign country and exported to another foreign country without being brought into the trader’s country. Another type is a merchandising trade which is a form of brokerage between exporter from a foreign country and importer from another foreign country. Both types have one thing in common that the goods are not crossed the trader’s country. The difference is that an intermediate trader directly participates in the contract and earn a difference between import and export amount, whereas a merchandising trader just arranges the transaction and earns a brokerage fee. The profits from the intermediate trade are considered as export records, while merchandising trade profits are not considered export records. In other words, only the intermediary trade is considered as an export. Also, the license types are different for each of them. An export license should be issued for the intermediate trade of Trigger List Items, whereas a brokerage license should be issued for the merchandising trade of Trigger List Items. The definition of export in the Foreign Trade Act includes intermediate trade for only goods, but technology is missing, although the sub-regulation specifies the intermediate trade including both. The technology need to be added as it can be the subject of intermediate trade in spite of intangible characteristics. Also, outreach activities are more needed as nuclear industry awareness on export control for both trades is low.

In South Korea, the master plan for high-level radioactive waste management, announced in 2016, suggested the construction and operation of intermediate storage facilities on a permanent disposal site and specified the adoption of dry storage in consideration of the ease of operation and expansion. As of 2021, the government is again reviewing its overarching policy on the back-end fuel cycles, including intermediate storage and permanent disposal. In the case of dry storage facilities, safety evaluation is being conducted using a combination of deterministic and probabilistic approaches, similar to that of nuclear power plants. The two methods are complementary, of which Probabilistic Safety Assessment (PSA) has the advantage of being able to identify key scenarios affecting safety, but its use in storage facilities has not been highlighted so far. However, depending on the spent fuel management phases such as loading, transportation, and storage, it may be not enough to capture effective and efficient safety evaluation only deterministically, and probabilistic methods may contribute to the evaluation of long-term operation or external events such as an earthquake. There have already been cases where PSA has been performed on a part of the nuclear fuel cycle through previous studies. This paper created the safety assessment model based on open sources such as the released EPRI reports, by targeting arbitrary intermediate storage facilities. The model considered the scenarios for loading, transportation, and storage, with human error respectively. It will be able to be modified and improved to fit domestic and specific intermediate storage facilities in the future.

A safety assessment of radioactive waste repositories is a mandatory requirement process because there are possible radiological hazards owing to radionuclide migration from radioactive waste to the biosphere. For a reliable safety assessment, it is important to establish a parameter database that reflects the site-specific characteristics of the disposal facility and repository site. From this perspective, solubility, a major geochemical parameter, has been chosen as an important parameter for modeling the migration behavior of radionuclides. The solubilities were derived for Am, Ni, Tc, and U, which were major radionuclides in this study, and on-site groundwater data reflecting the operational conditions of the Gyeongju low and intermediate level radioactive waste (LILW) repository were applied to reflect the site-specific characteristics. The radiation dose was derived by applying the solubility and radionuclide inventory data to the RESRAD-OFFSITE code, and sensitivity analysis of the dose according to the solubility variation was performed. As a result, owing to the low amount of radionuclide inventory, the dose variation was insignificant. The derived solubility can be used as the main input data for the safety assessment of the Gyeongju LILW repository in the future.
