This study developed an optimism improvement program and verified its effects. Seligman(1990) stated that optimism is not born but instead learned. His opinion was confirmed as an effective treatment by performing The Penn Prevention Program on children with depression. This study modified and complemented this program according to Korean children, and it developed a new optimism improvement program. To verify the effects of the program developed in this study, the program was conducted on a total of 57 fifth-grade elementary school students and first-grade middle school students. Fifty-eight persons as part of a waiting list control group in the same grade as the study subjects were also prepared. The optimism level of the group that participated in the program was significantly higher than that of the non-participants. This shows that alternative solution thinking ability was the mechanism of optimism improvement. In addition, as the result of checking whether or not alternative solution thinking ability and consequential thinking ability are key mediators of optimism improvement by means of parameter variables analysis, mediator effect of alternative solution thinking ability was verified while that of consequential thinking ability was not. This study is meaningful in that an optimism improvement program was developed according to Korean culture and actual conditions. It was economical as it could be performed in a shorter time than existing programs, and subjects were sufficient enough to verify the effects of the program.

Suggested improvement device of above problems is categorized as : 1. operational improvement; 1) research on street condition, 2) minimizing weaving, 3) research and rearrangement of bus stop, 4) PR and 2. institutional improvement: 1) consideration on the demand of other cars on EBL entry, 2) enhancement of supervision efficiency.

A Comparative Performance Study of an Ejector-Expansion Refrigeration Cycle Using R134a and its Alternatives: Application of Automobile Air Conditioning

Al-Chlaihawi Kadhim K. Idan,Kadhim Hakim T.,Yousif Ahmad Hashim 대한설비공학회 2021 International Journal Of Air-Conditioning and Refr Vol.29 No.4

In this study, the performance of ejector-expansion refrigeration cycle (EERC) with R134a alternative refrigerants (R152a, R1234yf, R404A, R407C, R507A and R600a) for automobile air-conditioning application is investigated numerically. The ejector is modeled with a constant mixing-pressure assumption taking into consideration the friction effect in the ejector mixing section. The studied refrigerants are compared based on the optimum area ratio, discharge temperature, compressor input power, volumetric cooling capacity, exergy destruction, COP, exergy efficiency and COP improvement. The results show that R152a and R1234yf have the closest performance to R134a and can be considered the most suitable alternative refrigerants for R134a. The COP and exergy efficiency are improved by 2.26% and 2.27%, respectively, using R152a compared to the use of R134a, whereas they are reduced by 2.89% and 2.88% using R1234yf. The volumetric cooling capacity is reduced for both R152a and R1234yf by 6.14% and 6.8%, respectively. In addition, the effect of compressor rotational speed on the performances is reported.

최창규(Choi, Chang Gyu),김항집(Kim, Hang-Jib) 한국지역개발학회 2012 韓國地域開發學會誌 Vol.24 No.5

Korean Government has promoted the development of the country and mostly focused on metropolitan regions and industrial hubs since 1960s. That has worked in some extents, but local small cities have been relatively excepted in economic and social developments. Those cities have had the spreading of deteriorating housing area as the two factors have declined. Recently the Korean Government and academics have tried to improve the residential condition in those area. It is hard to develop pin-pointing policies due to the lack of the analysis on those areas. This study tries to understand the current status of deteriorated housing areas in local small cities and suggest alternative improvements. By analyzing data from literatures and local governments, this study could find that the populations size of city is strongly related with the extent of deterioration of housing area. The structures, facilities, and sizes of housing are getting worse as the population size of cities become smaller. The deteriorated housing area’s conditions vary with the number of houses and infrastructure conditions. Withe the understanding of the current status, this study suggests the alternatives for the deteriorated housing area as following: developing affordable housing supply and repair model, increasing public participation and support system, and suggesting the total approaching system.

통합 하이브리드시스템의 압력강하 거동 및 바이오필터 담체의 미생물 population 분포

이은주 ( Eun Ju Lee ),임광희 ( Kwang-hee Lim ) 한국화학공학회 2022 Korean Chemical Engineering Research(HWAHAK KONGHA Vol.60 No.1

In this study, waste air containing ethanol and hydrogen sulfide, was treated by an integrated hybrid system composed of two alternatively-operating UV/photocatalytic reactor-process and biofilter processes of a biofilter system having two units with an improved design (R reactor) and a conventional biofilter (L reactor). Both a pressure drop (△p) per unit process of the integrated hybrid system and a microbe-population-distribution of each biofilter process were observed. The △p of the UV/photocatalytic reactor process turned out very negligible. The △p of the L reactor was observed to increase continuously to 4.0~5.0 mmH₂O (i.e., 5.0~6.25 mmH₂O/m). In case of R reactor, its △p showed the one below ca. 16~20% of the △p of the L reactor. Adopting such microbes-carrying biofilter media with high porosity as waste-tire crumb media, and the improved biofilter design, contributed to △p of this study, reduced by ca. 37~50% and 40~53%, respectively, from the reported △p of conventional biofilter packed with biofilter media of the mixture (50:50) of wood chip and wood bark. In addition, the △p of R reactor in this study, reduced by ca. 80% from the reported △p of conventional biofilter packed with biofilter media of the mixture (75:25) of scoria with high porosity and compost, was mainly attributed to adopting the improved biofilter design. On the other hand, in case of L reactor, the CFU counts in its lowest column was analyzed double as much as those in any other columns. However, in case of R reactor, its CFU counts were bigger by 50% than the one of L reactor and its microbes were evenly distributed at its higher and lower columns of R_dn reactor and R_up reactor. This phenomena was attributed to an even moisture distribution of 50~55% of R reactor at its higher and lower columns. Therefore, R reactor showed superb characteristics in terms of both △p and microbe-population-distribution, compared to L reactor.

통합 하이브리드시스템을 활용한 폐가스 처리 거동

이은주 ( Eun Ju Lee ),임광희 ( Kwang-hee Lim ) 한국화학공학회 2022 Korean Chemical Engineering Research(HWAHAK KONGHA Vol.60 No.1

In this study, integrated hybrid system (IHS) composed of two alternatively-operating UV/photocatalytic reactor (AOPR) process and biofilter processes of a biofilter system having two units (i.e., R_up and R_dn) with an improved design (R reactor) and a conventional biofilter (L reactor) was constructed, and its transient behavior was observed to perform the successful treatment of waste air containing ethanol and hydrogen sulfide (H₂S). At the IHS-operating stages of HA1, HA2 and HA3T of reversed feed direction, the AOPR process showed not only ethanol-removal efficiencies of 55, 50 and 45%, respectively, but also H₂S-removal efficiencies of 70, 60 and 37%, respectively. In particular, a drastic decrease of H₂S-removal efficiency at the stage of HA3T was observed due to a doubling of H₂S-inlet concentration fed to AOPR from 10 ppmv to 20 ppmv at the stage of HA3T. The order of ethanol-breakthroughs and the order of the magnitude of ethanol-removal efficiencies at the sampling ports of each unit of R reactor at the stages of HA1, HB1, HA2, HB2, and the first half of HA3T, were reversed, respectively, at the stages of the second half of HA3T and HB3T. In case of H₂S, R reactor did not show H₂S-breakthrough as prominent as the ethanol-breakthrough, but showed the trend similar to the ethanol-breakthrough.

군 개혁을 통한 인권개선:대만의 대체복무제도를 중심으로*

모춘흥 연세대학교(미래캠퍼스) 빈곤문제국제개발연구원 2023 地域發展硏究 Vol.32 No.2

본 연구는 양심적 병역거부자에 대한 대체복무제도 개선의 실마리를 찾기 위해서 한국과 유사한 정치・경제・안보상황과 병역 의무를 바라보는 국민들의 정서가 유사한 대만의 사례를 분석한다. 대만이 대체복무제도를 도입한 2000년 당시, 대만은 국방의 현대화와 함께 군 병력 규모의 축소에 따른 병역자원의 여유가 있었다. 이런 상황에서 대만 정부는 남는 병역자원을 사회 전반의 필요한 일에 활용하는 것이 필요하다는 군 개혁의 차원에서 대체복무제도를 도입했다. 이렇게 도입된 대만의 대체복무제도가 주는 함의는 기존의 병역제도를 논할 때 ‘형평성’과 ‘공정성’이라는 가치를 지나치게 고려하는 가운데 ‘인권’과 ‘양심의 자유’가 훼손된 것에 대한 반성과 안보환경의 변화, 그리고 국방의 현대화라는 차원에서 이해할 수 있다. 특히 대만 사례가 한국에 주는 가장 큰 시사점은 병역자원의 효과적 활용이 대체복무제도에 대한 긍정적 여론 형성에 기여할 수 있으며, 그 결과 인권개선의 효과가 가져올 수 있다는 점이다. 또한 기존의 군사안보 중심의 안보개념이 점차 경제사회, 문화적인 측면으로 확대되고 있는 상황에서 양심적 병역거부자에 대한 대체복무제도 개선과 안보환경에 대한 효과적 대응이 반드시 충돌하는 것은 아니라는 점에 주목할 필요가 있다. This study analyzes the case of Taiwan, where the political・economic・security situation and the people’s sentiment toward compulsory military service are similar to that of Korea, in order to find clues to improve the alternative military service for conscientious objectors in Korea. In 2000, when Taiwan introduced an alternative military service, they had plentiful military service resources due to the modernization of its national defense and the reduction in the size of its military forces. In this situation, the Taiwanese government introduced the alternative military service in the context of military reform, arguing that it would be desirable to use the surplus military service resources for the needs of society as a whole. The implications of Taiwan’s alternative military service are reflection on the damage to ‘human rights’ and ‘freedom of conscience’ and security environment while overly considering the values of ‘fairness’ and ‘equity’ when discussing the existing military service system. It can be understood in terms of changes in the Korean Peninsula and the modernization of national defense. In particular, the crucial implication of Taiwan’s case for Korea is that the effective use of military service resources can positively contribute to the formation of positive public opinion on the alternative military service, which can result in the improvement of human rights for conscientious objectors. In addition, it is necessary to note that the improvement of the alternative military service and effective response to the security environment do not necessarily conflict in a situation where the existing security concept centered on military security is gradually expanding to economic, social and cultural aspects.

조규찬 어문연구학회 2019 어문연구 Vol.102 No.-

본 연구는 충남대학교에서 이공계 학생들을 대상으로 운영 중인 <공학논문작성과 발표>의 문제점과 개선 방안을 실제 수업 사례를 토대로 살펴보았다. 이를 위하여 <공학논문작성과 발표>의 표준 강의안과 실제 수업에서 적용한 강의안을 비교해 보았다. 또한, 실제 수업에서 적용한 강의안을 토대로 15주차 강의를 진행하였을 경우 수업에 참여한 이공계 학생들의 요구가 무엇이었으며, 충족 과정에서 발생한 문제점이 무엇이었는지를 파악할 수 있었다. 그 결과, <공학논문작성과 발표>를 공학교육인증을 받기 위한 과정으로 운영하기 위해서는 크게 세 가지 문제점을 해결할 필요가 있음을 확인할 수 있었다. 그러나 이와 같은 문제점은 교수자 한 사람의 개인적인 노력으로만은 해결될 수 없으며, 제도적인 도움이 함께 이루어져야만 가능할 것이다. 그럼에도 불구하고 현재 발견된 문제점에 대한 개선 방안을 모색할 수 있는 계기를 이루어냈다는 점에서 유의미한 시도라고 할 수 있다. This study examined real class cases for problems and improvement alternatives of <Writing and Presenting Engineering Papers>, the class for science and engineering students in the Chungnam National University. For doing this, this study compared a standard lesson plan of <Writing and Presenting Engineering Papers> with a lesson plan applied to real classes. Also, this study could figure out what needs of students participating in classes are and what problems are when their needs are satisfied in the case of taking 15 week-lectures through the lesson plan applied to real classes. As a result, this study could realize necessities to solve three big problems for operating <Writing and Presenting Engineering Papers> as a process to get the engineering education accreditation. However, these problems could not be resolved by only personal efforts of a professor. For doing this, institutional supports are also necessary. Nevertheless, this study could be a significant and positive try in terms of gaining an opportunity seeking for improvement alternatives on problems found currently.
