The rapid development and progress of information and communication technology are bringing about changes in the field of education, and innovative methods in teaching-learning have been introduced and applied a lot in the actual field starting with the pandemic. Reflecting this trend, the purpose of this study is to examine the perception of prospective elementary school teachers on the use of edutech, which is widely used in the educational field after COVID-19. To this end, I analyzed the results of 7 major ideas selected at the Edutech Utilization Competition held by K University of Education and the focus group interview conducted with 2 pre-service teachers. As a result of the analysis, it was found that prospective elementary school teachers valued the necessity and importance of edutech-based classes. In addition, they were positively aware of the educational effect of edutech-based classes. To sum up, it could be predicted that edutech classes are also linked to the policies and plans of the Ministry of Education, and will play an important role in effectively guiding future learners while achieving the goals set by the curriculum.

This study aimed to elucidate the differences in nursing service experience according to the participants' characteristics and experience of hospitalization and to identify the relation between nursing service experience and perceptions of the health system. It analyzed the data from a "Survey of health care service experience" conducted among 574 participants who had been hospitalized. The results showed that the mean nursing service experience of participants who had never used other hospitals before hospitalization with over ten days of hospital stay was higher compared with the other participants. Moreover, those who used other hospitals before hospitalization reported lower nursing service experience scores. In the classification based on the change of the inpatient room, the difference in the nurse service experience according to the number of hospitalization days was significant only in patients who had no change in the inpatient room in the multi-person room. The nursing service experience scores were positively related to general satisfaction with the hospitalization experience, health system satisfaction, and trust in the health system. This finding implies that the nursing service experience should be interpreted by separating the inpatient experience, and the strategies to improve the nursing service are needed. In addition, the survey should include items related to the characteristics of medical institutions such as nurse staffing, to identify factors affecting the experience of nursing services.

2010년 기준 세계 물산업은 약 4,800억불 규모이며, 2025년에는 약 1조 달러 규모로 성장할 것으로 전망된다. 또한 기후변화 등의 요인으로 물산업의 범위는 물순환체계 전과정을 포괄하는 "유역종합개발+상하수도+대체수자원"으로 확장될 것으로 예측된다. 그러나 지금까지의 국내 물산업 육성은 주로 상하수도 분야 중심으로 국한되어, 기후변화에 대응한 유역종합개발 분야에 대한 시장 진출기회를 상실하고 있다. 상하수도 중심의 물산업은 이미 선진 메이저 기업들이 선점하여 치열한 경쟁이 벌어지고 있는 '레드오션'이라 할 수 있으므로, 새로운 물산업의 강국으로 부상하기 위해서는 우리가 가진 장점을 바탕으로 물산업의 새로운 영역을 개척하는 방안에 대한 연구가 필요한 시점이다. 본 연구는 먼저 국내외 물순환체계 전과정(유역종합개발+상하수도+대체수자원)에 대한 시장 조사을 통해 세계 물산업 시장을 프로젝트 유형별, 지역별로 분석하고, 이를 토대로 국내 물산업 육성과 해외진출을 위한 당면 과제를 다음과 같이 제시하였다. 첫째, 민관협력을 위한 제도적 틀을 형성할 필요가 있다. 정부의 역할이 매우 중요한데, 정부 또는 기금이 자금의 단순한 대부자에서 적극적인 투자자로 전환함으로서 국내 민간기업들의 해외시장 진입장벽을 낮추어 줄 필요가 있다. 정부 주도의 민관협력이 활성화되면 참여 기업의 재무적 리스크를 현저히 줄일 수 있다. 또한, 상하수도 운영 경험을 축적한 공기업이 해외진출 지원기능을 수행하도록 하여야 한다. 즉, 공기업이 민간 기업의 경쟁자가 아니라 지원자가 될 수 있도록 프레임을 바꿔주어야 한다. 둘째, 물산업 클러스터의 형성이다. 물산업 제조업은 대부분 중소 벤처기업으로 독자적인 해외진출이 곤란하므로, 물전문 공기업이 중소 벤처기업 육성 및 해외진출의 앵커 역할을 담당하는 것이 필요하다. 이스라엘이나 싱가포르의 물산업 클러스터처럼 Anchor 역할을 행하는 공기업과 민간기업이 장기적 협력관계를 구축할 수 있는 기반을 마련해야한다. 셋째, 신시장 역량의 창출이다. 기후변화로 크게 성장할 전망인 통합물관리 시장에 대한 전략적 접근이 요구된다. 우선 ODA 등 대외 원조자금을 활용하여 투자비가 적게 들고 정보를 선점할 수 있는 조사 설계부터 시작하여, 댐 및 수력개발, 상하수도 건설 운영 등에 단계적으로 접근할 수 있을 것이다. 또한, 향후 도입될 예정인 물인프라의 Smart 기술, 첨단 수처리 기술 등을 활용하여 새로운 시장을 개척해야 한다. 4대강살리기 사업, 해수담수화 등 조기에 경쟁우위를 갖출 수 있는 사업과 기술을 Flagship Project로 브랜드화하여 우리나라를 "물강국"으로 포지셔닝할 경우 세계 물시장 공략에 보다 효과적일 것으로 판단된다.

This study was aimed to develop blend films by rice by-product (rice-hull and rice-bran) and bio-degradable materials. The rice by-product was firstly prepared from the pulverizing for making fine powder. Bio-degradable materials could be prepared by melting at high temperature. The mixture of the fine powder of rice by-product and melted bio-degradable materials was then blended and cast into films. The obtained films were investigated on their morphology, secondary structures and properties by using SEM, ICP and ASTM, respectively. Mechanical properties and degradability of these films were measured and compared to those of the PE films. Mechanical strength of bio-films was higher than that of PE films, however elongation ratio showed lower percent than that of PE film. In addition, bio-film could be degraded into fragments within 3 months under the field condition of normal upland crop cultivation. Bio-degradable mulching film indicated great potential for agronomic use as a new source of bio-degradable material.

The first Protestant medical missionary, Horace Allen, came to Korea in 1884 and built the first western-style hospital, Jaejungwon. John Heron, Oliver Avison and other foreign medical doctors soon followed. They established hospitals and medical schools, and, by treating patients and educating native doctors, they disseminated and developed modern medicine in Korea. At the same time, they wrote letters and reports to their sponsoring agencies, as well as family and friends, thereby leaving a vast body of literature that is scattered all over the world. Since the end of the 19th century, the records left by foreign medical missionaries have been valuable resources for the study of Korean history. While all types of records, such as diaries, memoirs, reports and travel logs, are available, these tend to be exaggerated or unverifiable because they are unilateral records. In contrast, letters can be verified because they are bilateral records between the recipient and the sender, and cannot be modified or altered according to changes in circumstances. Despite the academic value of these materials, however, there have been insufficient efforts to discover or identify these primary data sources, or to systematically organize them for scholars. This paper identified 49 archival collections from 29 institutions in North America. After analyzing their academic value, the paper will explore digital humanities options in utilizing the letters for future scholarship.

Multi-functional urethane acrylate monomers as the curing agent of poly(phenylene ether) (PPE) were synthesized and then the urethane bond formation was checked by FTIR spectrometry and NMR analysis. The synthesized monomers were mixed with PPE and fabricated to dielectric substrates. After forming PPE/monomer composite sheets by a film coater, several sheets were laminated to a test substrate in a vacuum laminator and then its properties depending on the type and the amount of monomers, such as dielectric constant, dielectric loss, and peel strength, were measured. Between the two different hydroxyl acrylates, when the monomer synthesized with 2-hydroxy-3-phenoxypropyl acrylate containing a phenyl group was used as a curing agent, a smaller dielectric loss was obtained and the dielectric constant and loss decreased with a decrease in the amount of the monomer. The peel strength values of the test substrates, however, did not show any specific difference between the cases of two synthesized monomers. As a result, it was obtained the polymer substrate for high frequency application having peel strength of about 10 N, low dielectric constant of 2.54, and low dielectric loss of 0.0027 at 1 GHz.

The net function of the domestic medical insurance system is highly regarded, but due to the problem of incomplete coverage, the public wants to secure coverage through private medical insurance subscription. As a result, the subscription rate of private medical insurance has recently increased, and the billing rate has also increased. As the number of people seeking private medical insurance increased, workers at private medical insurance companies are experiencing increased job stress and side effects, especially for insurance reviewers who are in charge of paying insurance, such as communicating with customers who claimed insurance and contributing to the company's profit. In response, this study analyzed the effects of job stress on mental health of insurance reviewers and conducted a descriptive survey study to reduce job stress of insurance reviewers and promote mental health. The analysis shows that job stress for insurance reviewers has a significant impact on mental health (+). In detail, job stress has a significant impact on all four factors: social performance and self-confidence, depression, sleeping disturbance and anxiety, and general well-being and vitality. This study showed that job stress in insurance reviewers has a significant (+) impact on mental health. Job stress can cause side effects in organizational aspects, such as reducing enthusiasm for job performance and increasing turnover and resignation rates, but it can also worsen individual physical health and cause diseases such as depression and anxiety, causing mental health to be impoverished. Therefore, in order to prevent this, appropriate work stress prevention methods and countermeasures should be provided to help reduce work stress and improve mental health.

Experiments were conducted to investigate seed persistence of Chinese milk vetch(CMV) in naturally reseeded rice field in 2007~2009. The seed and pods with seeds were buried in rice field at 0, 5 and 10 cm depths and retrieved from the field at one to three month intervals from July to the following year March and determined change of seed dormancy and viability. In the second experiment, persistence of the CMV seeds in the naturally reseeded rice field at different tillage methods and soil depths were also investigated after rice harvest in autumn. Burial depths and durations affected recovery rate, dormancy and viability of CMV seed. The viability loss was faster and greater in the seed than the pod with seeds and on the soil surface than the 5 or 10 cm burial depths. The recovery rate of CMV seed was decreased starting from one month as seed burial and it was significantly decreased to 52~65% for the seed in September. However, unlike the seed burial, the nearly 100% CMV seeds were recovered for burial as pod with seeds even after four months burial in both 0 and 5 cm depths. However, the recovery rate was sharply declined to below 30% at October in 2007 in both seed and pods with seeds and in the 2008/2009 experiment. the 15~47% of CMV seeds still remained even after October. The CMV had high seed dormancy of 95%, showing only 4~5% germination at the beginning in June but the seed germination increased to 25 to 35% in seed and 55 to 61% in pod with seeds in September due to breakage of hard seed dormancy. The viability loss was faster in the seed than in the pod with seeds regardless of depths of placement in the soil base on decayed seeds. Also the seed placed on the soil surface lost viability faster than the 5~10 burial depths. On the other hand, field observation in the naturally reseeded CMV rice field showed that as many as 917~2,185 CMV seeds $m^2$ were from the 0~15 cm soil depth in the rotary tillage and 250~10,105 CMV seeds in minimum tillage treatmints. The recovered seed germinated 25~33%, 23~43% but still had high percentage of hard seed having 64~72% and 51~77% even after rice harvest in autumn. These results indicate that freshly harvested CMV seeds had high level of primary dormancy and the dormancy was gradually broken in soil with time during rice cultivation periods and appreciable number of CMV seeds remained even 4 month after burial in soil. CMV plant regenerated naturally from the remained seed bank at rice harvest time in autumn. The CMV seedling still emerged even after 2 years of continuous destructive killing of emerged CMV plant by rotary tillage in naturally reseeded CMV plant in rice field, indicating that CMV seeds do persistent as least two years in soil.

This study was conducted to evaluate microbial contamination levels of Korea traditional rice cakes such as Sirutteok, Garaetteok and Gyeongdan in the manufacturing process and environment. The microbial contamination levels such as total aerobic bacteria, fungi, coliforms, Escherichia coli, Staphylococcus aureus, Bacillus cereus and Clostridium perfringens of rice cake products were analyzed. The contamination levels of total aerobic bacteria, coliforms, fungi and B. cereus in raw materials were in the range of 2.4~4.5, ND~1.9, 1.2~2.1 and 1.0~2.1 log CFU/g, respectively. The microbial contamination levels of total aerobic bacteria, coliforms, fungi and B. cereus in manufacturing process of rice cakes were increased in the soaking and grinding steps and were decreased in steaming step. E. coli, S. aureus and C. perfringens were not detected in any manufacturing process and environment. The microbial contamination levels of raw materials and final products of rice cake were suitable for microbial safety standard in Korea. However, the manufacturing environment such as equipments and employee's sanitation were in trouble for microbial safety. The results of this study suggest that safety educatio n for personal hygiene and safetymanagement in processing environment are continuously required to assure safety in working environment and employee's individual hygiene.

As the privacy issues are all around the world, the intrusion into personal privacy is concerning. For that reason, government established the article from the personal information protection law that has to notice the privacy policy to users on the online site. and the matter of privacy invasion make concern toward behavior of online user. Although there are rules to carrying legal binding force in accordance with, because it is full of text and uncomfortable to read so that its readability is low. In the same context, each other has different state of understanding with the policy for personal information has been playing an important role. In this approach, companies and government do not think this over deeply and do just for what their practical use is. That is the reason why this research start, and the result expecting for real. As the result in the participant who cognize the privacy policy display pattern, they have certain type to do. In this article, the certain behavior doing is remarkable with the privacy policy. According to privacy concern, privacy fundamentalist reveals such a compromise reaction to protect their information when they know what information which the privacy manager of service provider collect. This study arrives at the result depending on the gap of privacy group that the group of checking the policy contents, especially the group which has high privacy concern, they move forward to protect their emotion and put a constructive plan into protective action. Otherwise, the group of unchecking the policy contents and following their own thinking of privacy policy are not deemed statistically significant. Therefore, this is considered to support more various implications than the previous issues and alternatives about privacy policy pattern and user protection behavior of privacy.
