딸기 ‘설향’ 품종에 대해 삽목 육묘의 조건을 확립하고자 삽수 채취용 모주 선택, 삽수의 적정 엽수 및 삽목 시기를 구명하였다. 삽수 채취는 육묘장 모주와 과실 수확 후 재배 식물체에서 채취하였고, 삽수의 엽수는 0, 1, 2장 그리고 삽목 시기는 6 월 4일부터 7월 9일까지 1주일 간격으로 하였다. 육묘장 삽수와 재배 식물체 삽수의 최종 생존율은 각각 99.5%, 98.7%로높았으며, 유의적인 차이는 없었다. 근수는 육묘장 삽수에서3.1개 많았고, 관부와 잎의 생육은 차이가 없었다. 과실 수량은 육묘장 삽수와 재배 식물체 삽수에서 각각 419.2g, 428.4g 이었지만 유의적인 차이는 없었다. 삽수의 엽수별 생존율은엽수 1, 2장에서 각각 98.1%, 98.3%로 높았고, 0장은 25.3% 로 현저히 낮았다. 근수는 엽수 1, 2장에서 각각 26.0개, 26.3 개로 엽수 0장의 23.5개에 비해 많았다. 관부와 엽의 생육에서는 엽수에 따른 유의적인 차이가 없었다. 과실 수량은 엽수 1, 2장에서 각각 424.4g, 421.5g으로, 0장 396.7g 보다 많았다. 삽목 시기에 따른 삽목 후 생존율은 97.2% 이상으로 높았으며, 처리 간의 유의적인 차이는 없었다. 묘의 지하부와 지상부그리고 관부의 생육은 6월 4일과 11일 삽목에서 가장 좋았다. 과실 수량은 6월 4일, 6월 11일 삽목에서 각각 433.3g, 426.4g 으로 가장 많았으며, 삽목 시기가 가장 늦었던 7월 9일 삽목에서는 384.5g으로 적었다. 딸기 삽목용 삽수 재료는 육묘장 삽수와 과실 수확을 마친 재배 식물체 삽수 모두 가능하였고, 삽수의 적정 엽수는 최소 1장 이상 그리고 경남 지역의 삽목 시기는 6월 4일-11일이 적합하였다. This study was conducted to investigate optimal conditions for cutting propagation of the strawberry cultivar “Sulhyang” through the collection methods of cuttings (runners tips), leaf number of cuttings, and cutting time. Cuttings were collected from the mother plant in the nursery bed (MP) and plants after fruit harvest (HP); the leaf number of cuttings was 0, 1, and 2, and the cutting time was at one-week intervals from June 4 to July 9. The survival rates for MP and HP cuttings were notably high, reaching 99.5% and 98.7%, respectively, but no significant difference was found. The number of roots were higher in MP cuttings, and there was no significant difference in crown and leaf growth. The fruit yields were 419.2 and 428.4 g, for MP and HP cuttings, respectively. The survival rates according to leaf number of cuttings were 98.1% and 98.3% for 1 and 2 remaining leaves, respectively, and remarkably lower at 25.3% for no remaining leaves. The root numbers were 26.0 and 26.3 for 1 and 2 remaining leaves, respectively, compared with 23.5 for no remaining leaves, with no significant differences in crown and leaf growth. The fruit yields were 424.4 and 421.5 g for 1 and 2 remaining leaves, respectively, and 396.7 g for no remaining leaves. The survival rates according to cutting time was over 97.2% in all cutting time without any difference in each treatment. The root, shoot, and crown of the nursery plant before planting showed the best growth in the cuttings on June 4 and 11, resulting in the highest fruit yields of 433.3 and 426.4 g, respectively, with the lowest yields at 384.5 g for cutting time on July 9. Both MP and HP materials proved suitable for strawberry cuttings. The optimal leaf number for cuttings was at least 1, and the optimal cutting time in Gyeongnam area was evaluated as around June 4-11.

Various oxide films are commonly used as a sacrificial layer or etch mask in the fabrication of microelectromechanical systems (MEMS). Large residual strain of these oxide films causes the wafer to bow, which can have detrimental effects on photolithography and other ensuing processes. This paper investigates the residual strain of tetraethoxysilane (TEOS), low temperature oxide (LTO), 7 wt% and 10 wt% phosphosilicate glass (PSG). Euler beams and a bent-beam strain sensor are used to measure the residual strain. A poly silicon layer is used as the sacrificial layer, which is selectively etched away by $XeF_2$. First, the residual strain of as-deposited films is measured, which is quite large. The residual strain of the films is also measured after annealing them not only at $500^{\circ}C$, $600^{\circ}C$, $700^{\circ}$ and $800^{\circ}C$ in $N_2$ environment for 1 hour but also at the conditions for depositing a $2\;{\mu}m$ thick polysilicon at $585^{\circ}C$ and $625^{\circ}C$. Our results show that the 7 wt% PSG is best suited as the sacrificial layer for $2\;{\mu}$ thick polysilicon processes.

Large residual strain of these oxide films cause the wafer to bow, which can have detrimental effects on photolithography and other ensuing processes. This paper investigates the residual strain of tetraethoxysilane (TEOS), low temperature oxide (LTO), 7wt% and lOwt% phosphosilicate glass (PSG). Euler beams and a bent-beam strain sensor are used to measure residual strain. A polysilicon layer is used as a sacrificial layer, which is selectively etched away by XeF_(2). First, the residual strain of as-deposited films is measured, which is quite large. These films are annealed at 500℃, 600℃, 700℃ and 800℃ for 1 hour and residual strain is measured. Then, the residual strain after annealing at the conditions for depositing a 2μm thick polysilicon at 585℃ and 625℃ are also measured. Our results show that the 7wt% PSG is best suited as the sacrificial layer for 2μm thick polysilicon processes.

중국 데이터 법제와 정책 방향에 관한 고찰

이상우 제주대학교 법과정책연구원 2023 법과 정책 Vol.29 No.1

China’s three data laws consist of Cybersecurity Law, Data Security Law, and Personal Information Protection Law. Together with the Civil Code, the three laws provide the legal basis for the policy to bolster China’s data economy. The three laws are different from the Korea’s three data privacy laws which was revised in 2020. The reason is that the China’s three laws play a role in strengthening data security in addition to the purpose of revitalizing the data economy. The structure of ‘Civil Code + three laws’ corresponds to the Korea’s three data privacy laws. In addition to this, the three laws support strengthening data security along with the National Security Law. In this article, the essence of the three laws was added to the existing perspective of ‘revitalizing the data economy’ with the perspective of ‘strengthening of the data security’. Specifically, the role of Civil Code and the three laws for ‘revitalization of the data economy’ was examined. The characteristics of data security inherent in the three laws and expected effects through convergence with the National Security Law were analyzed. As is well known, Korea and China are completely different political systems. That is why the way the two countries approach when a country establishes policies or legislates is completely different. Under the prerequisites, this article tried to understand China's approach, and then based on this understanding, implications were derived. It was intended to utilize this point of view to establish data laws and policies that fit the situation of Korea. This article gives you a good understanding of China’s approach. In addition, It derives implications for filling the gaps of the Korean legislative system for data security. It is hoped that it will contribute to the establishment of data laws that balances ‘revitalization of the data economy’ and ‘reinforcement of data security’. 「네트워크안전법」, 「데이터안전법」, 「개인정보보호법」으로 구성된 중국 데이터 3법(이하 ‘3법’)은 「민법전」과 함께 중국 데이터 경제 활성화 정책 추진의 법적 근거를 제공한다. 동 3법은 2020년 개정된 우리나라 데이터 3법과는 이질적인 부분이 있는데, 이는 중국의 3법이 내치를 위한 ‘데이터 경제 활성화’의 목적 외에도 외치를 위한 ‘데이터 안보 강화’의 역할을 함께 담당하고 있기 때문이다. ‘「민법전」 + 데이터 3법’의 구조가 그 성격상 우리나라 데이터 3법에 상응한다면, 중국의 3법은 내치를 위한 역할에 그치지 않고, 「국가안전법」과 함께 ‘데이터 안보 강화’라는 외치를 뒷받침하고 있다. 본고에서는 중국 데이터 법제를 중심으로 ‘데이터 경제 활성화(내치)’ 관점에, ‘데이터 안보 강화(외치)’라는 시각을 더하여 그 본질을 통찰하였다. 구체적으로는 ‘데이터 경제 활성화’를 위한 중국 「민법전」과 3법의 역할을 살펴보고, 동 3법에 내재된 데이터 안보적 성질이 「국가안전법」과의 융합을 통해 기대하는 효과를 검토하였으며, 중국의 접근 방법을 고찰함으로써 우리나라 데이터 법제의 공백 부분에 있어서 시사하는 바를 정리하였다. 주지하다시피 우리나라와 중국은 확연하게 다른 체제에 기반하고 있기 때문에, 정책 추진 및 입법에 있어서 양국의 접근방식은 근본적으로 다른 점이 있다. 이러한 전제하에 우리나라 실정에 맞는 데이터 법제 및 정책 수립을 위해 중국의 접근방식을 올바로 이해하고, 우리가 놓친 부분이 있는지를 돌아보는 데에 그 의의를 찾고자 하였다. 현재 우리나라 데이터 법제는 외치의 영역인 ‘데이터 안보 강화’와 관련하여 ‘데이터 안보 기본법’이 공백 상태이며, 현행 데이터 3법은 데이터 안보적 요소가 미비한 상황이다. 이에 본고를 통해 우리나라 데이터 법제가 ‘데이터 경제 활성화(내치)’와 ‘데이터 안보 강화(외치)’를 아우르는 균형 잡힌 모습으로 변화하여, 데이터 경제를 활성화시킴으로써 데이터 안보를 강화할 수 있는 기초체력을 갖추고, 강화된 데이터 안보를 바탕으로 국내 데이터 경제 활성화를 위한 정책을 적극적으로 펼칠 수 있는 환경이 조성되어야 할 것임을 제언하였다.

신화문학론(1) : 자연과 인간의 동일시 The Identification of Nature with Man

이상우 명지대학교 예체능연구소 1995 藝體能論集 Vol.5 No.-

There are clear indications that primitive people identified nature with man. Rulers, who were responsible for bumper crop to feed his subjects, were identified with the oxen or the dragon. Furthermore, particular plants or natural phenomena were personified and treated as human beings, and, as one readily finds in totemism, specific animals or plants became the subjects of ancestor worship. This tendency is also identified in their imitative incantations, which as based on the law of similarity. Mythologies that we see as peculiar, such as the Tangun Mythology and the Jumong Mythology, are in fact products of this mentality. When our ancestors talked about the birth of noble personages who gave birth to the nation, they invariably described the birth in terms of the life cycle of plants in which new life sprouts out of seeds and grows under the warm sun to bear bountiful fruits. They imagined that this noble being was the son of the woman who sprung up from the earth and the man who descended from the skies. Of course, variations on this basic prototype are indeed possible according to differing mythologies. It is this variation that hinders us from readily identifying common denominators among the many mythologies, and that compels us to see them as mere stories that entail many difficult and strange features. Haemosu(해모수) in the Jumong Mythology is a personification of sunlight, and also a parallel figure to Hwanung(환웅) in the Tangun Mythology. In addition, Yuhwa(유화) is the personification of a tree, and she is a variation on Ungnyo(웅녀), who prayed under the Shindansu(신단수) tree for a son. In this fashion, primitive people devised their own mythologies via their imaginative capacity to equate human beings with plants(or nature). The task of a modern day poet or novelist is hardly different to this. In other words, although we no longer find ourselves one with nature owing to our rational mentality, poets and novelists have somehow been able to retain much of the the imaginative capacity of the primitive people. For this reason, we are fascinated that a poet like Suh Jongju(서정주) would discover an image of a woman in her 40s in something like a chrysanthemum. As Northorp Frye tells us, a poet is one who finds pleasure in utilizing his power of imagination to search for an image in nature that is akin to man.

It is important to optimize process management, aiming not only at construction terms but also at finding general solution. This paper is focused on finding better methods for estimating construction term more accurately. There are two main problems in domestic estimation methods. Firstly, the characteristics of each construction fields are overlooked. Only numerical factors considered, and specific circumstances of each fields are excluded in estimating construction term. The second problem lack of understanding new environments of construction fields. Environments in construction fieids may vary by society and time, such as scarcity of skilled workers, and can seriously affect construction term. This paper suggested followings as a solution for what should considered in estimating construction term. 1) Reductable dates caused by "Form Construction" 2) Considering non-working ratio on holydays/national holydays. 3) Application of rainfall to term estimation for sensitive steps to weather. 4) Adjustment of recess during winter time. 5) Specially improved methods of inserting concrete for regions average temperature of which is higher than 25℃.
