The use of energy pile foundation has been increased for economic utilization of geothermal energy. In particular, a coil-shaped ground heat exchanger (GHE) is preferred than conventional U-shaped heat exchanger to ensure better efficiency of heat exchange rate. This paper presents experimental results by changing different pitch spaces of spiral coils. Joomunjin sand was filled in a steel box of which the size was $5m{\times}1m{\times}1m$. Thermal response tests (TRTs) were conducted to measure the ground thermal conductivity with temperatures of circulating water using line source model and ring coil model. Experimental results and analytical solutions were compared to validate the applicability of these models. Ring coil model showed more accurate similar results with experimental data rather than line source model and cylindrical source model.

In this paper, in order to prevent a fall accident that occurs while working without fastening the safety hook at a construction site, a method to detect whether the safety hook is fastened using two coils is proposed. Ansys' Maxwell, an electromagnetic wave analysis simulator, was used to analyze the magnetic field before and after the safety hook fastening, and the possibility of confirming the fastening of the safety hook using the difference in the mutual inductance change and the resulting current induced in the receiving coil was shown.

The gold buckle excavated from Seogam-ri Tomb No. 9(National Treasure No. 189), one of the oldest gold artifacts discovered within the Korean Peninsula, was created using granulation techniques. The buckle is made with 22.8K gold sheets and features a decorative design with seven dragons in repousse metalwork. The outlines of the dragons and the edge of the buckle are finished with 23.8K gold wires and granules. Some curved sections of the buckle are also covered with an extra sheet of 23.8K gold, possibly added to repair defects discovered during production or thereafter. Gold wire used to render the dragon's nostrils is slightly lower in purity(23.3K) and was probably preferred in this case due to its increased hardness. As a result, the metal is better able to retain the complex shape of the dragons' nostrils, created by rolling gold wire into spirals. The buckle's gold granules are found in small, medium and large sizes and are presumed to have been bonded using copper. The foreheads and the bodies of the seven dragons are inset with turquoise and the eyes are decorated with red cinnabar/vermillion(HgS).

Oligomeric extracts of poly(ethylene terephthalate-co-ethylene isophthalate)s [(PET/EI] are analyzed by high performance liquid chromatography(HPLC) and nuclear magnetic resonance spectroscopy (NMR). Existence of separated peaks for small cyclics of trimer and tetramer gives the existence of structural isomeric forms. NMR confirms that cyclization of PET/EI occurs more easily at the site of isophthaloyl unit.

이 연구의 목적은 카를로 몰리노(1905~1973)의 복합적인 특징을 그의 초현실적 공간구성 방식을 특별히 고려하여 분석하는 것에 있다. 몰리노는 가장 독창적인 현대 이탈리아 건축가들 중 한 명이다. 그는 생애동안 그의 작품들은 비평가들에게는 인정을 받지 못했다. 그의 반 순응적인 성격과 극심한 개인주의도 일조를 하였지만 가장 큰 이유는 그의 작품들이 그의 전문적인 활동과 다양한 개인적인 관심사 사이에서의 강박적인 상호작용에 기반을 두었기 때문이다. 그의 독창성은 그의 능력에 있는 것으로, 항공학, 자동차, 스키, 무대 디자인, 패션, 예로티즘, 문학 그리고 그 외 수많은 다양한 분야에서 얻었던 지식을 디자인하고 건축으로 변형하려는 그의 초현실주의 배경에서부터 나온다. 개인적인 집착으로 그의 작품을 키워가면서 몰리노는 당시 현대 건축의 모든 관습들을 깨고 전문적인 능숙함과 독특한 예술적 시야 사이에 걸려있는 독특한 디자인 표현을 보여주었다. 이 연구는 몰리노의 독특한 공간 구성 방식을 벗겨내기 위해 그의 배경, 즉 그가 열정적으로 탐구했던 연구 분야들과 전문적인 생산물 사이의 연결고리를 분석한다.

A 'Readymade' is an everyday object selected and designated as art. The term was coined by Marcel Duchamp to describe his artistic process based on the attempt to destroy the notion of the uniqueness of the art object: his influence went for beyond the art world affecting all design activities based on creativity. The purpose of this study is to investigate the ready-made technique from an educational point of view. Starting from Duchamp experience and his further influence on the design world, the study aims to demonstrate the value of the ready-made technique as a basic element in the education of young designers. The research method is based on the empirical observation of the results of the same project assigned to forty different students in different universities. The collected results were grouped in four families according to each specific generative method: constructive, conceptual, aggregative and elaborative. These four categories, derived by the observation of the results, represent tangible variations of the same disciplined technique. This flexibility demonstrates the value of the ready-made process as a foundation practice particularly indicated for young designers. These are the main skills students developed through its application to design projects; exploring and reconsidering attitude, recycling issues, new identity to familiar objects, focus on ideas.

Baculovirus was originally isolated from the alfalfa looper and contains a 134-kbp genome with 154 open reading frames (ORF). The major capsid protein VP39 together with some minor proteins forms the nucleocapsid ($21nm{\times}260nm$) that encloses the DNA with p6.9 protein. They are double-stranded, circular, supercoiled DNA molecules in a rod-shaped capsid. Wild-type baculoviruses exhibit both lytic and occluded life cycles that develop independently throughout the three phases of virus replication. Recombinant baculoviruses can transfer their vectors and express their recombinant proteins in a wide range of mammalian cell types. Especially, inclusion of a dominant selectable marker in these baculoviral vectors can express diverse recombinant genes in many cells. Baculoviral vectors were reconstructed with cytomegalovirus (CMV) promoter,uroplakin II promoter, polyhedron promoter, vesicular stomatitis virus G (VSVG), enhanced green fluorescent protein (EGFP), protein transduction domain (PTD) gene and so on. These reconstructed vectors were infected into various cell and cell lines. We performed transfection and expression of these recombinant vectors comparison with other control vectors. From this study, we knew that transfection and expression of these recombinant vectors have higher efficacy than any control vector. This work was supported by a grant from Mid-Career Researcher Program(NRF-2016R1A2B4016552) through the National Research Foundation of Korea(NRF) funded by the Ministry of Science, ICT & Future Planning(MSIP).

This thesis is research about the development and application of the panorama image in contemporary artwork, focusing on sculpture and installation. The samples of artworks are a selection of representatives from numerous examples of works that cannot be introduced without exceeding a reasonable scope of the thesis. A brief outline of the historical concepts of the perspective will describe the development of the panorama in itself. Some technical explanations and the practical use of the panorama with its link to 3-dimensional applications should bridge the explanation gap between the 2nd and 3rd dimensional usage of the panorama in contemporary artwork. Furthermore, some philosophical statements are proposed in the discussion. One of the main interests and initial motivation of this study was my personal believe that there is always a relationship between social philosophical values and the way a society sees or encounters visual structures. In other words the contemporary understanding of space and perspective is mirroring the actual zeitgeist and creates an exemplary visual aesthetics.

The white-spotted flower chafer Protaetia brevitarsis seulensis is a medicinally beneficial and important edible insect species. We previously performed an in silico analysis of the Protaetia brevitarsis seulensis transcriptome to identify putative antimicrobial peptides and then tested their antimicrobial and hemolytic activities. These peptides had potent antimicrobial activities against bacteria and yeast without inducing hemolysis. In the present study, the cationic antimicrobial peptide, protaetiamycine 2, was selected for further assessment of its anti-inflammatory properties in mouse macrophage Raw264.7 cells. Protaetiamycine 2 treatment of Raw264.7 cells suppressed LPS-induced nitric oxide production and reduced the expression of inducible nitric oxide synthase and cyclooxygenase-2, as determined by real-time PCR and western blotting. The expression of proinflammatory cytokines ($TNF-{\alpha}$, IL-6, and $IL-1{\beta}$) was also attenuated through the MAPKs and $NF-{\kappa}B$ signaling. We also confirmed that protaetiamycine 2 bound to bacterial cell membranes by a specific interaction with LPS. Collectively, these data obtained from LPS-induced Raw264.7 cells indicated that protaetiamycine 2 could have both antimicrobial and anti-inflammatory properties.
