The Act on the Punishment of Serious Accidents to Prevent Large-scale Disasters, including Ferry Sewol and Taean Thermal Power Plant, passed the National Assembly on January 8, 2021, and has been in effect since January 27, 2022. However, the law, in which the representative of the headquarters is unlimitedly responsible for each worker's accident, is somewhat unreasonable at a time when a company owns dozens to hundreds of construction sites due to the nature of the construction industry. I agree with the purpose of enacting the law to reduce chronic serious accidents at construction sites, but it is necessary to carefully reconsider the implementation of the law in that punishment alone cannot achieve industrial safety. Previous studies focused on revising the Occupational Safety and Health Act, but there are few studies on the impact on the construction industry after the implementation of the Serious Accident Act. Therefore, this study attempts to derive problems related to the application of the Serious Accident Act and present improvement measures. To this end, after analyzing previous studies, SWOT analysis was performed by applying the Delphi method to derive strengths, weaknesses, opportunities, and threats. In addition, the results of two surveys of safety experts such as public institutions, academia, and companies were reflected, and its countermeasures were presented as follows. S/O strategy: establishing on-site execution capabilities of health and safety management system; W/O strategy: expanding legal and system execution checks; S/T strategy: establishing a risk response system; W/T strategy: expanding consulting by external specialized institutions
코로나19 대유행은 우리 생활 전반 많은 변화를 초래하였다. 특히 노인을 포함한 사회적 약자들은 건강 위협과 빈곤, 사회적 고립, 디지털 배제 등의 다양한 위기에 노출되었고, 따라서 각별한 관심을 필요로 하고 있다. 노인은 코로나19 관련하여 신체적 문제(예컨대 높은 치명률, 만성질환 악화 등)와 심리·사회적인 문 제(예컨대 사회·여가활동 감소로 인한 고립, 우울감 등)를 동시에 겪는다. 이러한 문제는 위드코로나 시대에 주요 돌봄제공자인 가족의 부담을 가중시키고, 나아가 사회적 돌봄 부담 역시 가중시킨다. 우리나라 현재 이러한 위기상황 극복을 위하여 의료적·경제적·정서적 지원정책을 제공하고, 이를 통해 노인이 소외되지 않도록 많은 노력을 기울이고 있다. 하지만 즉각적·단기적인 조치에 따른 돌봄 사각지대 발생 등의 문제들 이 발생하고 있다. 이런 문제들을 해결하기 위해서는 거시적인 관점에서 사회안전망과 보건의료시스템 전 반을 재정비할 필요가 있으며, 노인돌봄 수요자의 요구와 노인인권 측면을 고려한 커뮤니티 케어의 실현을 앞당길 필요가 있을 것이다.
본 연구는 고속스핀에코 기법을 이용한 MRI 검사에서 영상 변수가 전자파 흡수율(SAR)과 온도 증가에 미치는 영향을 평가해 보고자 하였다. 이를 위해 인체 등가 조직 팬텀을 제작하였고 같은 조건에서 재위상화 RF의 FA와 ETL을 증가시키 며 MRI 검사를 시행하였다. SAR는 장비에서 계산된 두부 SAR값을 사용하였고 팬텀의 온도 변화는 양성자 공명 주파수를 이용해 계산하였다. 실험 결과, FA를 60°에서 180°까지 증가시켰을 때 SAR는 약 8배까지 상승하였고 팬텀의 온도 상승의 폭은 약 2.8배(0.21°-0.599°) 증가하였다. 그리고 다중 회귀 분석 결과, FA는 SAR와 온도 상승의 관계에서 표준화 계수 가 각각 0.935, 0.741로 나타나 높은 상관관계를 보였다. ETL은 15에서 30까지 증가시켰을 때 SAR는 약 2배 증가하였 다. 하지만 팬텀의 온도 상승 폭은 오히려 39.2%(0.53°-0.303°) 감소하였다. 다중 회귀 분석 결과에서도 ETL은 SAR의 관계에서 표준화 계수가 0.741로 양의 상관관계를 보였지만 온도 상승의 경우 표준화 계수가 –0.482로 나타나 음의 상관 관계가 있었다. 이는 ETL이 15에서 30까지 증가함에 따라 검사 시간이 약 43% 짧아져 전자파의 노출 시간이 감소한 것이 원인이 될 수 있다. 결국, FSE 기법을 이용한 MRI 검사에서는 재위상화 FA는 최소화하고 기준 SAR 범위 내에서 ETL을 최대로 적용하면 전자파로 인한 온도 상승을 최소화할 수 있어 환자 안전을 증진 시킬 수 있을 것으로 기대한다.
본 연구는 게임 이용동기가 인터넷게임 사용장애에 미치는 영향을 분석하였다. 이를 위하여 한국콘텐츠진흥 원의 게임이용자패널(2014~2018)의 상반기 조사 5개 연도 자료를 활용하였다. 게임이용자패널은 초·중·고등 학교 학생 2,000명의 표본으로 구성되었으며, 1차 연도부터 5차 연도까지 연구에 참여한 778명의 응답을 분 석에 활용하였다. 응답자의 특성으로 성별은 남성 381명(49.0%), 여성 397명(51.0%)이었고, 학생 분포는 1차 연도 기준으로 초등학생 287명(36.9%), 중학생 273명(35.1%), 고등학생 218명(28.0%)으로 이루어졌다. 종속변 수인 인터넷게임 사용장애는 Kimberly Young의 인터넷중독척도를 게임사용에 맞게 수정한 20문항을 활용하 여 측정하였고, 독립변수인 게임 이용동기는 Nick Yee의 게임이용척도를 수정한 10문항을 활용하여 측정하 였다. 주요 분석방법으로 MIMIC 모형분석을 활용하였다. 분석 결과를 요약하면 다음과 같다. 첫째, 보상과 현실도피 동기의 게임 이용은 5개 연도 자료 분석 결과 일관적으로 인터넷게임 사용장애와 정적인 관계가 있었다. 둘째, 보상 동기의 게임 이용의 표준화 영향계수는 도피 동기의 게임 이용의 표준화 영향계수보다 더 높은 수준으로 나타났다. 셋째, 통제변수 중에서 높은 불안감 수준을 지니고 있을수록, 남성일수록 일관 적으로 인터넷게임사용장애 수준이 높은 것으로 나타났다. 이러한 분석 결과를 바탕으로 DSM-5 진단기준과 관련한 정책적, 실천적 제언을 논의하였다.
While the use of metadiscourse in L2 writing has received considerable attention in the past, little effort has been made to examine how L2 writers’ use of metadiscourse in academic writing has evolved over time. In addressing this, the present study explored a diachronic evolution of interactional metadiscourse in research articles (RAs) published across a span of 40 years (1980-2021) in English Teaching. Based on 931 articles consisting of 6.4 million words, we examined whether the use of interactional metadiscourse has changed over the past 40 years. Our findings revealed that there was a global decrease in interactional metadiscourse over the past 40 years. While the frequency and diversity of interactional metadiscourse have slightly decreased over time, the proportion of each metadiscourse category remained consistent. The study further suggests that Korean L2 scholars who publish in English Teaching tend to hedge more than they boost or use attitude markers compared to those who publish in global journals.
In this paper, we investigate the requirements of QPA(Quality Process Audit), which is a process quality audit system for secondary defense contractors, compared with those of DQMS(Defense Quality Management System). And evaluate whether the deployment of QPA meets the DQMS certification requirements through the case example of Company H. The evaluation items of QPA are composed of five categories such as Material Management, Incoming Inspection, Manufacturing Process, Product Evaluation, and Packaging Management. The QPA requirements are mainly related to the chapter 7(support) and chapter 8(operation) of DQMS standards. In this view point, QPA can be expected as an effective audit for suppliers preparing for DQMS certification. In the case example, we evaluate the results and effects of improvement due to QPA and compare it with the case of DQMS. QPA can be used as appropriate quality management standards of secondary and tertiary defense contractors and can provide the basis guidelines for the preparation of implementation steps in DQMS certification.

Two kinds of mesocarbon microbeads (MCMBs) with different chemical composition have been synthesized. The MCMBs were molded and heat treated at temperatures above 2000 °C to obtain graphite blocks. The effects of chemical composition of MCMBs on the pore morphology, carbon texture and thermal properties of the derived graphite blocks have been explored. The pore morphology was investigated by small angle X-ray scattering technique and a graphitization-induced morphology transition was observed. When the graphitic crystallite size exceeded a threshold value, the association of crystallites and migration of randomly distributed pores took place extensively. For the graphite blocks made of MCMBs which had light components with higher aromaticity value, the growth of crystallites caused a significant enhancement in thermal conductivity for the specimens. However, for the other kind of MCMBs, their light components tended to form solid porous carbon texture after graphitization, and the thermal conductivity coefficients of their graphite blocks could only increase slightly as crystallites grew. It was suggested that the thermal resistance at the granule’s boundary became noticeable in the latter case and thus the growth of thermal conductivity coefficients was prominently hindered.
Natural environmental resources are considered a prospective source of microorganisms capable of producing biocatalysts with great potential in industrial areas. Arable soil fertilized with peat moss is a habitat for various microorganisms. The present research focused on the isolation and identification of hydrolase-producing bacteria that thrive at a broad temperature range. In this study, a total of 33 strains were isolated from arable soil fertilized with peat moss (Silla Garden in Busan, South Korea). The isolated bacteria were mesophiles and thermophiles with a wide temperature range. Taxonomic identification showed that the isolated strains belonged to 2 phyla, 5 families, 10 genera, and 24 species. Subsequently, the isolated strains were screened for hydrolase (amylase, lipase, and protease) activity. All isolates possessed activity of at least one enzyme and six bacterial isolates produced combined extracellular enzymes. Diversity of soil bacteria species in the present study suggest the potential of soil bacteria in the various industrial applications.
To develop quality-improved muffins, the influence of the partial replacement of wheat flour with lemon balm powder (LBP) on their quality characteristics was analyzed. Studies were carried out to examine the supplementation of different percentages of LBP (2%, 4%, 6%, and 8%) on the quality characteristics of LBP muffins. The incorporation of LBP significantly affected the physicochemical parameters of muffins. Such incorporation at different levels significantly decreased pH, moisture content, baking loss, hardness, and color parameters, including L*, a*, and b* values of muffins (p<0.05). No significant effect of LBP substitution was found in height changes (p>0.05). Finally, the consumer acceptance test indicated that the highest levels of LBP incorporation (i.e., 8%) had a considerably adverse effect on consumer preferences in all attributes. In contrast, muffins with moderate levels of LBP (4%) showed a good and satisfactory sensorial acceptance in general. Thus, LBP was successfully employed in muffins, improving quality and broadening its potential applications in other bakery products.
The War on Terror launched by the US against Islamic terrorist groups persisted through the Bush-Obama-Trump administrations for nearly 20 years before President Biden completely withdrew the US forces from Afghanistan by the end of August 2021. These military interventions are noticeable examples of American unilateralism in the Middle East. The War on Terror has been severely criticized by the global community as military actions without just cause and lacking grounds under international law. This research aims to critically evaluate the War on Terror in terms of legal and political theories of war now that twenty years of American unilateralism in the Middle East is over. In this article, the author examines other underlying reasons for, and the outcomes of, the war against terrorist groups. He will also suggest peaceful means to fundamentally resolve the Middle East conflict with a view to preventing war in other world regions.
이 글은 예이츠와 엘리엇에 대한 연구로서 이 두 시인 각각의 시적 화 자에 대한 표현 방법을 살펴 본 것이다. 예이츠의 경우, 비교적 시적 화자가 곧 예이 츠 자신과 일치하는 경향을 보이고 있는데 그는 주로 상징에 의하여 시적화자의 의도 를 드러내고 있다. 반면에 엘리엇은 작품창작과정에서 그 자신을 드러내지 않기 위해 서 시적 화자를 다른 인물들로 설정하는 경향을 보인다. 그러나 두 시인에게 공통점은 시적 화자를 드러내거나 감추고 있지만 객관성을 추구한다는 점에 있어서는 서로 유 사하다고 볼 수 있다.
This study was undertaken to compare meal skipping, snacking, and weight perceptions between students on-campus living alone and off-campus living with parents, in an urban college in the United States. The self-report survey was completed by 219 college students (on-campus=100, off-campus=119) between April and May 2012. Two-thirds (67%) of the respondents skipped at least one meal in the past week, and most participants showed strong desires to lose weight despite their normal/under-weight status. Significant differences between the two groups were obtained for the reason to skip a meal and the type of snack consumed. Compared to on-campus students, significantly higher values were obtained for off-campus students for choosing ‘no time to prepare’ as a meal skipping reason for lunch and dinner, and ‘sweets’ as a preferred snack. In addition to the group comparison, multiple regression results indicate that the body mass index (BMI) positively correlates with meal skipping and snacking frequencies. Younger students and female students were determined to have a higher frequency of meal skipping and morning snacking. Future research is required to study the dietary factors associated with living arrangements, to help college students develop healthy eating habits.
The bacterial soft-rot disease is one of the most critical diseases in vegetables such as Chinese cabbage. The researchers isolated two bacteria (Pseudomonas kribbensis and Pantoea vagans) from diseased tissue samples of Chinese cabbages and confirmed them as being the strains that cause soft-rot disease. Lactic-acid bacteria (LAB), were screened and used to control soft-rot disease bacteria. The researchers tested the treatments with hypochlorous acid water (HAW) and LAB supernatant to control soft-rot disease bacteria. The tests confirmed that treatments with the HAW (over 120 ppm) or LAB (Lactobacillus plantarum PL203) culture supernatants (0.5 mL) completely controlled both P. kribbensis and P. vagans.
