Acknowledging the limited opportunities faced by learners of Korean in the US, this study investigates the efficacy and challenges of immersive Korean language-focus residential programs in US college dormitories. Through an examination of a Korean language dormitory (called K-house) at a Midwestern university in the US, the current study sheds light on the optimal experiences and effective immersive environments that college langauge dormitory programs in the US can foster for both linguistic and cultural learning of Korean. By delving deeper into the specific programming and experiences of K-house residents, the study demonstrates that K-house facilitates access to Korean language and culture, enhances motivation of Korean language study, and cultivates a sense of belonging to the K-house community among K-house residents. Additionally, the findings of this study provide valuable insights for designing effective Korean language dormitory programs that promote language and cultural immersion in the context of teaching and learning Korean as a foreign language. Furthermore, this study offers suggestions for future research in this area.

Molybdenum-tungsten (Mo-W) alloy sputtering targets are widely utilized in fields like electronics, nanotechnology, sensors, and as gate electrodes for TFT-LCDs, owing to their superior properties such as hightemperature stability, low thermal expansion coefficient, electrical conductivity, and corrosion resistance. To achieve optimal performance in application, these targets’ purity, relative density, and grain size of these targets must be carefully controlled. We utilized nanopowders, prepared via the Pechini method, to obtain uniform and fine powders, then carried out spark plasma sintering (SPS) to densify these powders. Our studies revealed that the sintered compacts made from these nanopowders exhibited outstanding features, such as a high relative density of more than 99%, consistent grain size of 3.43 μm, and shape, absence of preferred orientation.

This study aimed to examine the operations of school food services to prevent the spread of coronavirus disease 2019 (COVID-19) in schools nationwide. The survey data on school food service operations targeting nutrition teachers and nutritionists at 1,023 schools in 2020 and 1,177 schools in 2021 were used. The year 2021 saw an increase compared to 2020 in the following: ‘average days to be served with meals for a year (144.5 vs. 184.7)', 'provided meals to all students (92.3% vs. 96.6%)', 'utilization of additional staff for foodservice assistance (33.4% vs. 38.8%)', 'installation of partitions (61.2% vs. 83.8%)', 'provision of general diet (96.1% vs. 99.1%)', and 'use of kitchen utensils (91.3% vs. 95.1%)', 'use of cafeteria water cup (9.9% vs. 31.0%)' and 'use of drinking water in school (46.8% vs. 52.1%)'. Compared to 2020, in 2021, it was confirmed that the school food service operations stabilized due to the increase in the normal school attendance rate and that systems were in place for operations during the COVID-19 pandemic. In the future, it will be necessary to develop manuals and special recipes necessary for responding to infectious diseases, and to operate a manpower pool that can quickly find replacement personnel if required.

The purpose of this study was to examine changes in serving frequency of elementary school meal before and after the COVID-19 pandemic. Number of menus provided in June and July of 2019 and 2020 were compared for 300 elementary schools in Korea. As a result, the serving frequency of la carte and dessert was increased after COVID-19. In addition, frequencies of main dishes such as pork cutlet, chicken, sweet and sour pork, hamburger steak, and so on using processed food were increased after COVID-19. Because of the longer serving time due to staggered serving, cook's working time for serving meals became longer. Therefore, it was judged that the number of servings of processed food was increased rather than the menu with a large amount of preprocessing work. Moreover, among desserts, fruits showed increased serving frequency. Serving frequencies for juice and dairy products were also increased. However, increased servings of juice and dairy products could increase sugar intake. Thus, a careful plan for menu composition is needed to provide balanced nutrients to students under emergency situations such as an infectious disease.

The army is concerned about the decrease in enlistment resources due to the low birth rate and the weakening of military combat power due to the shortening of the military service period. Now, the military's quantitative growth is no longer limited and it is a time for qualitative growth. To this end, the Army has been applying the Israeli learning method Havruta to recruit training to improve the quality of training since 2019. After applying Havruta, several scholars have studied the effect of recruit training applying Havruta. As a result, it was verified that recruit training applying Havruta improves the inner motive, creativity, and military service value of trainees. This study investigated how trainees' inner motive, creativity, and military service value affect their satisfaction and achievement. In addition, it was studied whether the effect of recruit training applied with Havruta on achievement differs according to the educational background (high school graduate or higher) and military family (professional soldiers within 4th degree) of the trainees. To this end, a survey was conducted on 472 recruits, and the structural relationship between each variable and the moderating effect were analyzed using the structural equation model. As a result of the study, military service value did not affect training satisfaction. Also, there was a difference in the effect of creativity on training satisfaction according to the educational background of new recruits, and there was a difference in the effect of military service value on training satisfaction and training achievement according to military family members. The purpose of this study is to contribute to the improvement of the army's recruit training development plan and effective training system.

The demand for novel strains has been rising in the domestic market to increase the production of sclerotia from Wolfiporia hoelen. To improve strain breeding efficiency, we investigated whether single-nucleotide polymorphisms (SNPs) in the RNA polymerase II subunit (RPB2) gene, which may be linked to the mating type locus, are useful for distinguishing monokaryons from dikaryons in Korean W. hoelen strains. We designed a specific primer set to efficiently amplify a region of RPB2 using PCR with the genomic DNA of 12 cultivated strains and 31 wild strains of W. hoelen collected from Korea. Nucleotide sequences of the PCR-amplified RPB2 genes were determined and analyzed for the presence of SNPs among the 43 W. hoelen strains. Previously reported SNP loci were detected in the RPB2 gene of all W. hoelen strains tested. However, these previously reported SNP loci could not be applied to differentiate monokaryons from dikaryons in approximately one-third of Korean wild strains with homozygous genotypes. Three additional SNPs in the RPB2 gene, which may improve the ability to distinguish monokaryons from dikaryons, were identified by searching through the multiple sequence alignments of the 43 W. hoelen strains. The applicability of these three novel SNPs, together with the previously known SNPs, in the RPB2 gene to W. hoelen strain breeding was verified by examining the hybrid strains and their parental strains.

Recently, the number and scale of projects being carried out within the enterprise are increasing. Accordingly, many companies are competitively introducing a Project Management Office (PMO) to efficiently manage these projects, allocate resources, and effectively link the projects and corporate strategies. However, the project manager who directly manages the project wants to receive support from the PMO in many areas for successful project management, but the project manager does not like to be interfered with by the PMO. On the other hand, the PMO may not be able to satisfy all the requirements of each PM as PMO oversees the entire project with limited resources. In addition, since the PMO must monitor and control the project and support the project according to the priorities of each project, conflicts with each PM can be formed. Therefore, in this study, based on the case of a company, the difference between the perceptions of PMs and PMOs about the importance of the required roles of PMOs is to be examined. As a result of the study, it was confirmed that the core functions and sub-functions of PMO, which PMO members and PMs consider important, are different. It was identified that the PMs valued the PMO function that would be helpful for their successful project execution. On the other hand, PMO members revealed that they had a relatively high priority for the roles to monitor and control project performance for which they were directly responsible.

In addition to physical risks such as electrical, chemical, and mechanic ones in the workplace, psychosocial risks are also raising as an important issue in recent years in connection with human rights and work-life balance policies. The purpose of this study is to confirm the degree of effect of the psychosocial risk management plan at the workplace on workers through logistic regression analysis. Input data for logistic regression analysis is the results of a survey of 4,558 people conducted by the Institute for Occupational Safety and Health were used. There are 9 independent variables, including the change a workplace and confidential counseling, and the dependent variable is whether the worker feels the effect on the psychosocial risk management plan. As a result of this study, changes in work organization, dispute resolution procedures, provision of education program, notification of the impact of psychosocial risks on safety and health, and the persons in charge of solving psychosocial problems are shown effective in reducing worker’s psychosocial risks. This study drives which of the management plans implemented to reduce the psychosocial risk of workers in the workplace are effective, so it can contribute to the development of psychosocial risk management plans in the future.

무분별한 산업화로 인한 스카이라인의 무질서, 자연경관 오염 등은 경관의 훼손을 가속화시킨다. 이에 국토의 경관을 보다 효율적으로 관리, 조성 및 복원하기 위하여 현재 환경부에서는 시행되어지 고 있는 개발사업 등을 대상으로 자연 경관 심의지침을 도입하였다. 제도에 입각하여 사업유형을 분류한 후, 정성적 평가를 시행하는 국내 지침 특성 상, 평가자에 의해 결과가 달라져 주관적이며 이는 곧 신뢰성의 문제로 이어진다. 반면 개발 대상지 각각의 평가 인자들을 도출한 후, 정성적, 정량 적 평가를 병행하는 영국의 경관영향평가는 지침의 유연성으로 인해 경관의 특이점을 반영하며 주 관적 관점 또한 최소화되어진다. 본 연구에서는 국내 및 영국의 경관영향평가에 대한 고찰과 영국 노썸버랜드 경관영향평가 사례 분석을 통하여 국내의 경관영향평가의 한계점과 보완 가능성을 제시 하였다. 이는 국내외 경관영향평가에 대한 기초적 연구로, 향후 이어질 경관영향평가의 세부적인 가이드라인 개발 또는 정책 수립에 합리적인 발전 방안 제시에 기여할 수 있을 것으로 예상된다.

신선 버섯의 수확 후 관리 기술은 2000년대까지 출원의 증가와 감소를 반복하는 경향을 보이다가 2010년대에 들어서 꾸준한 증가세를 나타내고 있어, 신선 농산물의 수확 후 관리 기술이 시대의 흐름에 부합하는 기술임을 알 수 있다. 주요 출원인에 대한 특허출원은 일본이 전체 출원 중에서 가장 많은 특허를 출원하였으며 대부분의 국가에서 내국인의 특허출원 비중이 높게 나타나 자국 중심의 출원 경향을 보이고 있다. 신선 버섯의 수확 후 포장 기술은 초반에 출원인 및 출원 건수가 감소하였다가, 최근 출원인 및 출원 건수가 증가하여 회복기 단계에 있으며, 저장기술은 최근 출원인 수와 출원 건수가 대폭 증가하여 성장기의 단계로 평가된다. 신선 버섯의 수확 후 관리 기술은 주로 다국적 기업과 국가 연구기관에서 다수의 특허를 보유하고 있는 것으로 나타났으며, 이는 해당 기술의 연구개발 및 상업화가 활발하게 이루어지고 있음을 시사하였다.

이 연구는 대학캠퍼스의 구성원의 풍부한 감성․기억․체험을 통해서 습득된 캠퍼스의 시각과 청각의 경관에 대한 이미지를 형성하는 심리적 요인을 찾아내어 경관 평가를 위한 의미구조를 파악하는 것, 그리고 대학 캠퍼스의 시각과 청각 경관의 만족도에 영향을 미치는 평가 요인에 대한 상대적 중요도를 파악하는 데 목표가 있다. 전남대학교 용봉캠퍼스 구성원들을 대상으로 설문조사하여 시각과 청각의 경관 이미지에 대한 평가요인과 상대적 중요도를 분석하였다. 시각 경관의 이미지는 활력․정취, 매력성, 청결성, 현대성, 통일성, 복잡성, 개방성의 7가지 요인이 관여하고, 시각 경관의 만족도에 영향을 미치는 중요도는 매력성> 활력․정취>청결성>현대성>통일성>개방성의 순으로 구성된다. 청각 경관의 이미지는 정감, 활기, 평온성, 변동성의 4가지 요인이 관여하고, 청각 경관의 만족도에 영향을 미치는 중요도는 정감>평온성>활기>변동성의 순으로 구성된다. 종합만족도에 미치는 영향은 시각 경관의 만족도가 청각 경관의 만족도보다 약간 높은 것으로 나타났다. 이 연구로부터 전남대학교 용봉캠퍼스의 구성원들이 파악하는 시각과 청각의 경관 이미지의 표현이 어떤 의미나 가치를 나타내고 있는지 확인가능하며, 심리적 경관의 이미지를 어떻게 물리적 가치로 치환해 낼 수 있는 지는 추후의 과제로 남아있다. 이 연구는 이제까지 양적으로 크게 성장해 온 대학캠퍼스의 경관의 문제를 보다 질적인 측면으로 확대하고 다가올 미래의 경관 문제를 종합적으로 파악하고 해결하기 위한 시도이다. 또한 지금까지 시각에만 머물러 있거나 의존해 왔던 경관 연구를 청각이라는 소리풍경(soundscape)의 문제로 확대한다는 점에서 기존의 경관 연구를 한 단계 발전시킬 수 있다는 점에 의의가 있다.

This study investigated the effect of offering eco-friendly fashion items on consumers’ perceived image of stores and their intention to purchase food in a hybrid cafe setting. The data were collected using an online survey of 465 adults aged 20 to 49 years. In order to compare ‘a general cafe’ where only food is sold and ‘a hybrid cafe’ which offers eco-friendly fashion items as well as food, we developed two store types (general×hybrid) with two store designs (modern×eco-friendly) as stimuli, resulting in four scenarios. The results indicated that offering eco-friendly fashion items at a cafe did not significantly affect consumers’ perceived eco-friendly image of the store. Further, this negatively affected consumers’ perceived healthy and tasty images of the store and intention to purchase food. Such negative effects on the healthy and tasty images of the store increased in the store with a modern design. In conclusion, offering eco-friendly fashion items at cafes may not contribute to enhancing the stores’ images or sales.

본 연구는 장애인의 취업에 영향을 미치는 생태학적 요인들, 예컨대 인구·사회학적 요인, 취업관련 요 인, 정신적 건강요인, 장애 및 건강요인을 탐색하였다. 이에 한국장애인고용공단 고용개발원의 2016년 장애인고용 패널조사를 활용하여 회귀분석을 실시하였다. 이를 중심으로 연구결과를 정리하면, 인구·사 회학적 요인 중에서는 성별과 배우자 유무, 사회활동참여가 취업에 영향을 미치는 것으로 나타났다. 이 를 통해 가정을 이루어는 것이 장애인의 경제적 자립에 긍정적인 영향을 미친다는 것을 알 수 있었다. 취업관련 요인 중에서는 학력과 자격증, 공공취업서비스 경험, 민간취업서비스 경험, 주변인의 취업알 선 경험 등이 취업에 영향을 미치는 것으로 나타났고, 정신적 건강요인 중에서는 우울감 인지와 일상생 활 만족도가 취업에 영향을 미치는 것으로 나타났다. 이를 통해 교육기관의 사회적 역할 및 접근성이 매우 중요하다는 사실을 파악할 수 있었다. 장애 및 건강요인 중에서는 장애정도와 주관적 건강상태, 일상생활 도움제공자 유무, 음주여부 등이 장애인의 취업에 영향을 미치는 것으로 나타났다. 본 연구는 이러한 결과를 토대로 장애인의 취업 및 경제적 자립을 위한 방안을 제언하였으며, 더불어 장애인정책이 향후 사회통합과 자립생활을 증진할 수 있도록 경제적 자립을 촉진하는 방향으로 재편되어야 함을 주장하였다.
