본 연구에서는 과학 탐구 키움 프로그램이 초등학생의 과학 긍정경험 지표(과학학습정서, 과학학습동기, 과학 관련 자아개념, 과학 관련 진로포부, 과학 관련 태도)에 미치는 영향을 살펴보고 이를 바탕으로 초등학생의 과학 탐구 및 과학 긍정경험 신장 방안을 고찰하여 시사점을 도출하고자 하였다. 연구 대상은 과학 탐구 키움 프로그램에 참여한 연구 집단 30명과 비교 집단 30명이며, 검사 도구는 총35문항의 과학 긍정경험 지표 검사와 서술 문항으로 구성되었고 사전·사후에 투입 및 회수하여 분석하였다. 연구 결과를 살펴보면 첫째, 과학 탐구 키움 프로그램은 초등학생의 과학학습정서, 과학학습동기, 과학 관련 자아개념, 과학 관련 진로포부, 과학 관련 태도에 유의한 영향을 주는 것으로 나타났다. 또한, 코로나19 속에서 오프라인뿐만 아니라 온라인 혹은 온·오프라인 연계 과학 탐구 활동이 적용되고 있으며 이런 과학 탐구 활동도 초등학생의 과학 관련 태도에 긍정적 효과가 있는 것으로 나타났다. 둘째, 과학 탐구 키움 프로그램은 초등학생의 과학 긍정경험 지표 전체에도 유의한 영향을 주며 초등학생의 과학 탐구 키움 프로그램 참여 여부는 과학 긍정경험 지표 중에서 사후 과학학습정서 및 사후 과학 관련 태도, 사후 과학 관련 자아개념, 사후 과학학습동기 및 사후 과학 관련 진로포부 순으로 영향이 큰 것으로 나타났다. 그리고 초등학생의 과학 탐구 키움 프로그램 참여 여부에 따라 과학수업에 대한 생각의 변화 양상이 다르고 과학 탐구 키움 프로그램 활동 참여 학생의 소감 역시 긍정적인 것을 확인하였다. 이와 같은 연구 결과를 고려해보면 초등학생의 과학학습 정서와 과학 관련 태도 신장을 위해서는 체험활동 및 상호소통이 강조된 프로그램을 다양한 과학 탐구 수업에서 지도할 수 있도록 구성해야 하고, 과학학습동기 신장을 위해서는 일회성 활동이 아닌 과학 탐구 프로젝트로 과학 글쓰기, 실생활 연계 활동 등을 연계성 있게 구성해야 한다. 그리고 초등학생의 과학 관련 자아개념 신장을 위해서는 학생 본인의 내적 인식이나 자신감뿐만 아니라 교사와 동료에게서도 긍정적 영향을 받을 수 있는 학습 분위기와 환경을 조성할 필요가 있고, 과학 관련 진로포부 신장을 위해서는 학생에게 가장 큰 영향을 주는 요인인 과학교육 활동 속에서 진로 연계 활동이 이루어져야 한다. In this study, we wanted to examine the effect of the science inquiry development program on elementary students’ positive experiences about science and to derive implications by considering ways to enhance science inquiry and positive experiences about science. The subjects of the study were 30 researchers and 30 comparative groups, and the test-tool consisted of 35 positive experiences about science, and descriptive questions. The results are as follows. The science inquiry development program has been shown to have a significant impact on elementary students’ science academic emotion, science learning motivation, science-related self-concept, science-related career aspiration, and science-related attitude. In addition, science inquiry activities linked online or online and offline as well as offline activities are applied within COVID-19, and these science inquiry activities have a positive effect on elementary students' science-related attitude. And depending on the elementary students’ participation in the science inquiry development program, the changes in the way they thoughts about science classes are different, the student's thoughts on participating in the science inquiry development program activities were also positive. Considering result like this, In order to increase the science academic emotion and science-related attitude of elementary students, programs emphasizing experience and interaction need to be guided in various science inquiry classes. And for expanding the science learning motivation, scientific writing and real-life linking activities should be constructed in a way that is not a one-time activity but a science inquiry project. In order to develop science-related self-concept for elementary students, it is necessary to create a learning atmosphere and environment that can be positively influenced by teachers and colleagues as well as students' internal perceptions and confidence. For increasing science-related career aspiration, career-linked activities must be carried out in science education activities, which are the most influential factors for students.

휴직과 복직에 관한 법적 쟁점 -사용자의 휴직명령 및 복직 거부에 대한 정당성 판단을 중심으로-

노승민 ( Roh¸ Seung-min ) 홍익대학교 법학연구소 2020 홍익법학 Vol.21 No.3

사용자는 기업의 지속적 경영을 위해 최적화된 구조로 노동력의 활용을 도모하며, 이를 위해 근로자의 채용과 배치, 전직, 휴직, 대기발령 등 이른바 기업경영상의 인사권을 가진다. 인사권은 근로계약관계를 매개로 하여 업무상 필요한 범위 내에서 사용자에게 상당한 재량권이 인정되는 것이므로, 사용자는 인사권에 근거하여 정당한 사유가 있는 경우에는 휴직을 명할 수 있다. 이러한 휴직은 취업규칙 또는 단체협약에 그 사유에 관하여 규정하고 있는 것이 일반적이다. 다만, 사용자에게 규정상 일정한 사유를 근거로 한 휴직명령권이 주어져 있는 경우라도 당해 휴직규정의 설정목적과 실제기능, 휴직명령권 발동의 합리성 여부 및 그로 인한 근로자가 받게 될 신분상·경제상의 불이익 등 구체적인 사정을 모두 참작하여 근로자가 상당한 기간에 걸쳐 근로의 제공을 할 수 없다거나 근로제공을 함이 매우 부적당하다고 인정되는 경우에만 정당성을 인정받을 수 있다. 다만, 사용자의 귀책사유(주로 경영상의 이유)에 의한 휴직명령의 경우, 이는 사실상의 휴업으로 보아 근로기준법 제46조에 의하여 원칙적으로 평균임금의 70%에 해당하는 수당을 지급하여야 할 것이다. 그러나 근로자의 동의 없이 사용자가 경영상 이유에 의한 무급휴직을 행사할 수 있는지 여부가 문제되는바, 이때의 휴직은 해고회피를 위한 노력으로서 행하여야 할 것이며, 근로기준법 제46조에서 보장된 휴업수당 청구권마저 배제될 수 있을 정도로 불가피한 경영상의 요건 및 회사의 휴직명령권 행사의 합리성 여부가 무급휴직의 정당성 여부에 있어서 중요한 판단기준이 될 것이다. 휴직은 잠정적으로 근로제공이 정지되는 기간이기 때문에 휴직기간이 만료되거나 휴직사유가 소멸하면 사용자는 취업규칙 또는 단체협약에 정한 복직절차에 따라 근로자를 복직시킬 의무가 있다. 만일 사용자가 정당한 이유 없이 복직을 거부하는 경우, 근로기준법 제23조 제1항에 따른 제한을 받는다. 한편, 단체협약 또는 취업규칙에 근로자가 복직하지 않으면 자진 퇴직한 것으로 규정(이른바 ‘당연퇴직조항’)하고 있는데, 이는 즉시 당연퇴직 효과가 발생하는 것이 아니라 해고사유를 규정한 것으로 해석해야 한다. 이 경우 해고의 정당성 여부는 근로자의 귀책사유 여부, 휴직사유의 소멸 여부, 회사업무에 지장을 초래하는 정도 등을 종합적으로 고려하여 판단하여야 할 것이다. 마찬가지로 형식적으로 부여된 휴직기간이 너무 짧은 경우나 아직 휴직사유가 해소되지는 않았지만 가까운 시일 내로 정상적인 근로능력을 회복할 수 있는 사정이 있는 경우에 단지 휴직기간 종료와 해당 시점에서 근로능력이 회복되지 않았다는 이유로 인한 당연퇴직 조치에 대해서는 그 정당성을 쉽사리 인정할 수는 없다고 할 것이다. ⅰ) Employers seek to utilize the labor force of an optimized structure for the sustainable management of the company, and for this purpose, they have the so-called corporate management personnel rights such as hiring and placement of workers, change of jobs, leave of work, and suspension from work. Since the human resource right is a means of allowing considerable discretion to the employer within the scope necessary for work through the labor contract relationship, the employer may order leave from work if there is a justifiable reason based on the personnel right. ⅱ) The reasons for such leave are generally stipulated in the employment rules or collective agreements. However, even if the employer is given the right to order leave based on certain reasons according to the regulations,'the purpose and actual function of the leave rule, whether it is reasonable to exercise the right to leave order, and the status and economic disadvantages that the worker will receive. Taking into account all circumstances, justification can be recognized only when an employee is unable to provide work for a considerable period of time or it is deemed very inappropriate to provide work. ⅲ) In the case of a leave of absence order due to reasons attributable to the employer, this is considered as a de facto shutdown, and in principle, an allowance equivalent to 70% of the average wage should be paid in accordance with Article 46 of the Labor Standards Act. In this case, an amount less than that amount or unpaid leave is possible, subject to the consent of the worker. However, it is a question whether the employer can exercise unpaid leave for management reasons without the consent of the worker. In this case, it is inevitable that even the right to claim the employee's leave of absence as a security device guaranteed in Article 46 of the Labor Standards Act can be excluded The verification of management requirements and the reasonableness of the company's exercise of the right to order leave will be an important criterion for determining the legitimacy of unpaid leave. ⅳ) Because leave of absence is a period in which the provision of work is temporarily suspended, the employer is obligated to reinstate the employee according to the employment rules or the reinstatement procedures set forth in the collective agreement when the period of leave expires or the reason for the leave of absence expires. If an employer refuses to return to work without a justifiable reason, Article 23, Paragraph 1 of the Labor Standards Act has the character of a general provision to protect the employee from the employer's disposition. On the other hand, in general, if a worker does not return to work according to a collective agreement or employment rules, it is prescribed as voluntary retirement. However, this should be interpreted as specifying the reasons for dismissal, not as reasons for retirement. v) Lastly, with respect to the relief for an unfair leave order, there is no penalty for the case where an employer gives an employee an unfair leave under the current law. However, if there is an order for unpaid leave that lacks legitimate reasons and procedures, the relevant worker may file an application for relief from unfair leave to the Labor Commission and receive relief after being recognized as an unfair leave order (Article 28, Paragraph 1 of the Labor Standards Act). In addition, since unfair leave is invalidated by the judiciary, it is possible to find a way to obtain judicial relief by filing a lawsuit to confirm the invalidation of the disposition of leave at the court.

신선비를 중심으로 본 설화 <구렁덩덩 신선비>의 불균형적 관계 맺기 양상과 문학치료적 의미

이승민 ( Lee¸ Seung-min ),김정애 ( Kim¸ Jeong-ae ) 한국문학치료학회 2021 문학치료연구 Vol.60 No.-

본고는 설화 <구렁덩덩 신선비>에 나타나는 신선비의 불균형적인 정서표출 방식과 그에 따른 인간관계 맺기 방식에 방점을 두고 <구렁덩덩 신선비>가 궁극적으로 누구를 위한 이야기인지, 누구에게 힘을 실어줄 수 있는 지를 확인하고자 하였다. 그리고 신선비의 자기중심적인 관계 맺기 방식에 대해 끝까지 감내하며 신선비와의 관계 회복을 위해 노력하고자 하는 셋째 딸의 모습이 문학치료 상담 과정에서 어떤 의의를 가질 수 있는지도 아울러 고찰하였다. 분석의 결과는 다음과 같다. 먼저 신선비와 셋째딸의 불균형적인 관계 맺기 방식은 다음 과정을 통해 드러난다. 첫째, <구렁덩덩 신선비>에서 신선비가 아내를 떠나는 이유는 아내의 실수를 무관심과 불신으로 이해하는 데에서 문제가 발생한 것이라 할 수 있다. 둘째, 떠나는 신선비의 정서는 떠나는 이가 원하는 때에 그가 원하는 방식으로 풀리게 된다고 할 수 있는데, 이는 그때를 위해서는 아내의 기다림과 인내가 요구된다. 이러한 일방적이고 불균형적인 관계 맺기 방식에도 불구하고 셋째딸이 이 모든 해결의 부담을 떠안는 것은 심약한 존재의 회복 능력을 마련해줄 수 있는 유일한 주체가 셋째딸이기 때문이며, 이는 인간중심치료의 원리와도 맞닿아 있음을 확인할 수 있었다. 일관되고 지속적인 지지와 존중은 패배적이고 부정적인 자기 평가를 하는 신선비에게 새로운 자기가치를 구조화하는 데 기여할 수 있음을 보여준다고 할 수 있다. 이러한 맥락은 최근 방영한 TV 프로그램 <우리 이혼했어요>의 사례를 통해서도 적용 가능함을 시사한다. 따라서 <구렁덩덩 신선비>를 활용한 문학치료 상담은 내담자의 자기보고를 활성화하는 계기가 되며, 서정시의 서사화하는 과정은 내담자의 문제적 특성을 객관적으로 관찰할 수 있는 기회를 제공할 것으로 전망된다. The main focus was on the disproportionate emotional expression of Shin Seonbi in the folk tale < GureongDeongDeong Sinseonbi > and the subsequent way of establishing relationships, and to see who the < GureongDeongDeong Sinseonbi > could ultimately be for and who it could empower. In addition, the third daughter, who endured the self-centered relationship of Sinseonbi to the end and tried to restore her relationship with Sinseonbi, also considered what significance she could have in the literary therapy counseling process. The results of the analysis are as follows: First of all, Sin Sang-bi and her third daughter's disproportionate way of making relationships are revealed through the following process. First, the reason why Sin Sang-bi leaves her wife in "Pierce Sinseonbi" can be said to have caused problems in understanding her mistakes as indifference and distrust. Second, the sentiment of leaving freshness can be said to be solved in the way that the leaving person wants when he wants, which requires his wife's patience and patience. Despite this unilateral and disproportionate approach to relationships, the third daughter bears the burden of all these solutions because she is the only one who can provide the resilience of a weak being, which is also in line with Carl Rogers' principle of human respect counseling. Consistent and continuous support and respect show that Sinseonbi, who makes defeated and negative self-evaluations, can contribute to structuring new self-worth. In this context, the latest TV show, "We're Divorced." The case suggests that it is also applicable. Therefore, literary therapy counseling using < GureongDeongDeong Sinseonbi > is expected to activate the self-report of the counsellor, and the narrative process of lyric poetry is expected to provide an opportunity to objectively observe the problematic characteristics of the counsellor.

근세 한일관계 관련 물품교류 연구 현황과 과제

이승민 ( Lee¸ Seung Min ) 한서대학교 동양고전연구소 2021 동방학 Vol.- No.45

이 논문은 근세를 대상으로 1990년대 이후 한국에서 발표된 논문 가운데 조선과 일본 사이의 물품교류와 직·간접적으로 관련된 연구 성과를 중심으로 연구의 현황과 특징, 그리고 앞으로의 과제를 소개하는 것을 목적으로 한다. 그동안의 물품교류 관련 연구는 통신사·문위행 등의 외교사행과 왜관에 도항하는 일본사신 관련 물품교류 및 공·사무역 등을 통한 연구가 주를 이루었다. 최근에는 그동안 연구가 진행되지 않은 개별 물품에 관한 연구로 확대되어 가고 있는데, 물품의 종류는 구체적으로는 약재류·동물류·음식류·문방구류·서적류·피물류·직물류·도자류·회화류 등으로 매우 다양하다. 본고에서는 주로 역사학계에서 이루어진 물품교류 현황에 대해 검토했지만, 사실 물품이라는 주제는 하나의 학문 영역으로 귀속되기 어렵다. 물품은 인간의 모든 생활과 상호 교류에 쓰인 도구의 총체로서, 물품에 내재된 특징과 역사성에 따라 다양한 학문분과 간의 연구 협력을 전개할 수 있는 주제가 된다. 따라서 물품을 키워드로 폭넓은 학제적 융합이 필요하다. 또한 한국과 일본이라는 단일지역에서 탈피해 한·중·일과 더 나아가서는 동유라시아 차원으로 연구 대상 지역을 확대할 필요가 있다. 그리고 단순한 생산 차원에서 한 단계 더 나아가 그것이 어떻게 생산되어 어떤 경로를 통해 교역·유통되고 어느 지역의 어느 계층을 중심으로 소비되었는지에 관한 총체적인 연구가 필요하다고 생각된다. The purpose of this paper is to introduce the current status, characteristics, and future tasks of the research centered on the exchange of goods between Joseon and Japan directly and indirectly among the papers published in Korea after the 1990s. Until now, research on commodity exchange was mainly conducted through diplomatic envoys such as Tongshinsa(通信使) and Munuihaeng(問慰行), as well as commodity exchange and public and private trade related to Japanese envoys sailing to Waegwan(倭館). Recently, it has been expanding to research on individual items that have not been studied. Specifically, the types of goods vary widely from medicinal ingredients, animals, foods, stationery, books, leather, textiles, ceramics, and paintings. In this paper, I reviewed the current status of commodity exchanges in the historical community. In fact, however, it is difficult to attribute goods to one academic area. Goods are the aggregate of tools used in everything used in everyday life, and in every human life and interaction. Research cooperation between various academic divisions can be carried out according to the characteristics and historical characteristics inherent in the goods. Therefore, a wide range of academic convergence is needed for the keyword ‘goods’. It is also necessary to pay attention to the analysis of goods produced, traded, distributed, and consumed at the level of East Eurasia, moving away from a single region of Korea and Japan. Also I think a holistic study is needed on what goods are being distributed and consumed, how they are produced and traded through what channels, and where and what classes they are consumed around.

Effect of temperature on single-and mixed-strain fermentation of ruminant feeds

( Seungmin Woo ),( Sooah Kim ),( Suji Ye ),( Soo Rin Kim ),( Jeongman Seol ),( Uyeh Daniel Dooyum ),( Junhee Kim ),( Dong Hyuck Hong ),( Jong Nam Kim ),( Yushin Ha ) 한국축산학회(구 한국동물자원과학회) 2020 한국축산학회지 Vol.62 No.2

Use of raw feedstuffs for livestock is limited by low digestibility. Recently, fermentation of feedstuffs has been highlighted as a new way to improve nutrient absorption through the production of organic acids using inoculated microorganisms, which can also play a probiotic role. However, standard procedures for feedstuff fermentation have not been clearly defined because the process is influenced by climatic variation, and an analytical standard for fermented feedstuffs is lacking. This study aimed to evaluate the microbiological and biochemical changes of feedstuffs during fermentation at temperatures corresponding to different seasons (10℃, 20℃, 30℃, and 40℃). We also investigated the effects of yeast, lactic acid bacteria (LAB), and Bacillus spp. on fermentation and determined the results of their interactions during fermentation. The viable cells were observed within 8 days in single-strain fermentation. However, when feedstuffs were inoculated with a culture of mixed strains, LAB were predominant at low temperatures (10℃ and 20℃), while Bacillus spp. was predominant at high temperatures (30℃ and 40℃). A significant drop in pH from 6.5 to 4.3 was observed when LAB was the dominant strain in the culture, which correlated with the concentrations of lactic acid. Slight ethanol production was detected above 20℃ regardless of the incubation temperature, suggesting active metabolism of yeast, despite this organism making up a marginal portion of the microbes in the mixed culture. These results suggested that fermentation temperature significantly affects microbiological profiles and biochemical parameters, such as pH and the lactic acid concentration, of fermented feedstuffs. Our data provide valuable information for the determination of industrial standards for fermented feedstuffs.

Passive increase in driving force in vortex-induced vibration of a semi-hollow cylinder for Reynolds number 200

Seungmin Kang,Sungmin Ryu 대한기계학회 2020 JOURNAL OF MECHANICAL SCIENCE AND TECHNOLOGY Vol.34 No.6

We present a semi-hollow body as an effective strategy to increase the driving force for vortex-induced vibrations (VIVs) of a circular cylinder. The hollow-body concept is evaluated numerically at Reynolds number Re = 200 and in a range of reduced velocity 3 ≤ U red≤ 8 with a mass-spring system released to vibrate in the transverse direction. Our numerical solutions reveal that, compared with solid-cylinder counterparts, the net transverse force is increased significantly through the semi-hollow body. The transverse force acting on the inner surface is found to be developed as a consequence of semi-confined flows driven by the cylinder oscillation. Furthermore, it is shown that the inner force has a phase difference with respect to the force acting on the outer surface. Based on a systematic force analysis, the appreciable increase in the transverse force is attributed to the constructive interference between the inner and outer forces.

The Effect of Security Awareness Training on the Use of Biometric Authentication: Focusing on the Protection Motivational Behaviors

Seungmin Jung,Joo Yeon Park 한국데이타베이스학회 2020 Journal of information technology applications & m Vol.27 No.2

The purpose of this study is to investigate the behavioral factors affecting the security attitude and intention to use biometrics password based on the protection motivation theory. This study also investigates security awareness training to understand trust, privacy, and security vulnerability regarding biometric authentication password. This empirical analysis reveals security awareness training boosts the protection motivational factors that affect on the behavior and intention of using biometric authentication passwords. This study also indicates that biometric authentication passwords can be used when the overall belief in a biometric system is present. After all, security awareness training enhances the belief of biometric passwords and increase the motivation to protect security threats. The study will provide insights into protecting security vulnerability with security awareness training.

Quantification of VIV-driven energy transfer for a circular cylinder with a pair of bumps at Reynolds number 150

Seungmin Kang,Sungmin Ryu,Simon Song 대한기계학회 2020 JOURNAL OF MECHANICAL SCIENCE AND TECHNOLOGY Vol.34 No.3

Vortex-induced vibration (VIV) based energy conversion is a promising methodology to generate electricity by utilizing the flow energy neglected and eventually dissipated in nature, as the power generation process is sustainable and free from emission of pollutants. In this vein, micro-scale energy convertors driven in low-Reynolds-number flows have caught the attention for engineering applications. As the performance of the convertors highly depends on the acting forces or VIV responses, VIV amplifications are necessary to elevate the power output or energy conversion efficiency toward a level of engineering practicability. The attachment of a pair of bumps on an elastically mounted circular cylinder was demonstrated as an effective way to elevate the energy output for VIV-based energy convertors. However, most of relevant studies were conducted for turbulent flows as high-capacity energy convertors are of significant interest for direct engineering applications. On the other hand, the effects of the bumps on the energy transfer have rarely been studied for low Reynolds number flows. This paper then aims to quantify the effects of the circumferential locations of a pair of bumps on the energy transfer ratio in a single circular cylinder VIV configuration for Reynolds number 150. The circumferential location of the bumps is optimized under the synchronization condition, and this is compared with the plain cylinder VIV configuration; the energy transfer ratio is appreciably elevated when the bumps are placed at θ = 60 or 75-degree.
