(연구배경 및 목적) 디지털 패러다임은 새로운 건축의 형태와 공간의 구조를 요구하게 되었고 디지털 패러다임에 따른 변화는 정형화된 대량생산의 중심적 디자인이 아닌 복잡하고 유기적인 형태의 새로운 조형생성에 집중이 되었다. 그중 블로비즘(blobism)은 오브젝트에 각지고 표준화된 형태를 벗어나 이음새가 없는 복잡한 형태를 표현하는 탁월한 능력으로 디자이너에게 새로운 조형성을 주어 블롭의 관련 연구는 계속 진행되었다. 블롭은 끊임없이 다양한 형태로 변화하며 합리적이면서 미적인 형태를 가지고 있고 이질적인 결합을 통하여 비동질적인 공간을 생성한다. 생성된 비동질적인 공간은 관찰자와 상호작용으로 연속적인 공간감과 탈중심적인 경계를 보이며 새로운 공간감을 창출하여 블롭은 오늘날 건축과 공간을 생성하는 중요한 도구가 되었다. 본 연구의 목적은 블로비즘의 조형특성의 이론과 개념, 디자인 원리를 분석하고 발현되는 조형성을 도출하여 블롭이 가지고 있는 새로운 조형적 가능성을 찾고 분석을 통하여 블로비즘의 비동질적 공간에 의미와 가치를 찾고자 한다. (연구방법) 블로비즘의 개념과 비동질성의 배경인 질 들뢰즈와 펠릭스 가타리의 리좀(Rhizome)과 폴드(Fold)의 개념을 알아보고 블롭이 갖는 조형성을 분석하여 블로비즘의 비동질적 디지털 형태변형 및 생성기법과 제작방법을 연구하고 앞선 개념들이 어떻게 적용이 되었는지 사례와 함께 알아보고 공간의 비동질성을 도출하고자 한다. (결과) 블롭은 이질적인 결합을 통해 유동적인 형태생성을 하며 비동질적인 공간을 창출한다. 이러한 블롭의 비동질적 공간은 리좀과 폴드의 개념을 통해 알아본 결과 리좀은 접속, 이접, 통접의 특성을 가지고 있으며 이질적인 결합을 통해 새로운 형태를 생성하고 이러한 형태는 중심이 없고 어디든 결합이 가능하며 본질의 형태를 지닌채 독립적인 형태를 만들어낸다. 폴드의 유동성, 연속성 특성은 객체가 지닌 속성은 끊임없이 이어져 연속적인 운동성을 보여주며 연속적인 내적 질서는 다른 형태와의 결합으로인해 무수한 중첩적인 형태를 만들어낸다. 이렇게 도출된 특성을 그래스호퍼를 이용하여 형태생성 실험결과를 사례에 대입한 결과 블로비즘의 비동질적 공간은 관찰자와 공간의 관계 속에서 시야의 긴장감과 중심이 없는 모호한 경계성을 도출할 수 있었다. (결론) 비동질적 공간은 실제로 멈추어 있지만, 공간 속에서 유연한 흐름의 운동성을 보여줌으로 물체가 흐르는 시간성을 느낄 수 있게 해주고 유동적인 흐름은 공간이 스스로 움직이는 것이 아니라 사용자의 입장과 시선에 따라 방향성이 변화하는 인터렉티브한 시야를 주어 일정한 형태를 유지하는 것이 아닌 계속해서 변화하는 것 같은 인식을 공간 속에서 보여준다. 연구를 통해 블로비즘의 유기적인 형태는 단순히 유연해 보이는 것이 아닌 공간 속에서 사용자에게 다양한 시각을 줌으로 인식과 지각적 사고에서 새로운 가능성을 보였고 사용자의 지각적 움직임을 갖은 잠재적 유동 공간은 새로운 조형적 사고와 시야를 나타낼 수 있을 것이며 더 많은 연구가 필요하다. (Background and Purpose) Digital paradigm requests new architectural type and spatial structure; such a change focuses on new complicated and systematic shape formation types. Among them, blobism gives the designer a new format―with its superior ability to express an object as a seamless, complicated shape, aside from being angulated and standardized. Thus, the study of Blob has been conducted. Blobs create inhomogeneous spaces through different combinations that continuously change into various reasonable and aesthetic shapes. Blobs become important tools in generating architecture and space today by creating a new sense of continuous inhomogeneous space with a decentralized boundary for interaction with the observer. The purpose of this study is to determine the meaning and value of the inhomogeneous space of blobism by finding new formative possibilities and conducting an analysis on Blob formativeness properties, thus revealing the theory, concept, and design principle of the formative characteristics of blobism. (Method) I determined the inhomogeneity of the space by investigating the concept of the rhizome and fold by Gilles Deleuze and flity and executing the analysis of blobism and the background of inhomogeneity, and studying inhomogeneous digital shape transform and generation method and manufacturing method of blobism. (Results) Blobs create inhomogeneous spaces, generating flexible shapes by different combinations. Rhizomes have connection, disjonction, and conjunction characteristics and generate new shapes by different combination. As it does not have a center, it is possible to combine anything and make individual shapes which have essential shapes. The liquidity and continuity characteristic of the fold shows continuous motility by connecting endlessly for the properties of the object, and continuous internal order makes countless overlapping shapes by the combination with other shapes. Inhomogeneous space of blobism can draw an ambiguous borderline without tension of sight and center in the relationship between the observer and space based on the result substitutes the shape generating inspection result of these drawing characteristic in the example using Grasshopper. (Conclusions) Heterogeneous space is actually stopped, however, it reveals the temporality with which the object is flowing by showing flexible flowing motility in space, and the floating flowing shows the awareness of continuous changing by giving interactive sight changing direction according to the situation and the line of sight and not the space moving by itself. Based on this study, the systematic shape of blobism shows new possibilities in the recognition and perceptual thinking in the space by giving various sights to the user which are not shown as simply flexible. Moreover, potential flowing space with the user’s perceptual motion could show new formative thinking and sight, and should therefore, be more carefully studied.

신석기시대 입지 환경에 따른 따비의 제작방법 -암사동·운서동 유적 출토품을 중심으로-

김영준 ( Kim¸ Youngjun ) 단국사학회 2020 史學志 Vol.60 No.-

이 글에서는 신석기시대에 구릉지와 충적지 주거지 유적에서 출토되는 따비의 제작기술 차이를 확인하고, 이러한 차이가 왜 나타나는지 살펴보았다. 한강 본류역에는 지형상 구릉지와 충적지에 신석기시대 주거지 유적이 확인되며, 이들 유적에서는 대표적인 뗀석기로 따비가 공통적으로 출토되고 있다. 하지만 지금까지 선행연구들은 따비의 형태분류가 중심이어서 이들 유적 출토 따비를 하나의 범주로 분류하여 입지 환경에 따라 나타나는 다양한 기술적 측면을 소홀히 다루었다. 충적지를 대표하는 암사동 유적 출토 따비의 경우 돌감으로는 돌결면이 발달하지 않은 조직이 치밀한 자갈돌 각섬암과 응회암을 이용하였고, 구릉지를 대표하는 운서동 유적 출토 따비의 경우 돌결면이 매우 발달한 모난돌 편암을 이용하였다. 입지환경 별 따비의 밑감은 암사동 유적의 경우 너비격지를 운서동 유적의 경우 모난돌 조각을 이용하여 따비 제작에 사용하였다. 이러한 제작기술의 차이는 결국 입지환경에 따른 사용방법에 차이, 즉 장착 유무에서 기인하였다고 판단된다. 충적지 유적인 암사동 유적 따비는 장착없이 사용된 도구로 파악되며, 구릉지 유적인 운서동 유적 따비는 목제에 장착하기 위해 만들어진 따비임이 제작기술에서 확인된다. This article explains the technical differences of manufacturing weederplow derived from residential sites located in alluvion or hill areas, and then tries to approach the reason why these differences are made. Neolithic residential sites are confirmed, which are located in alluvion or hill areas of main river valley in Hangang river, and weederplow is one of the representative remains from the sites. However, according to the precedent studies, they did not pay attention to various technical aspects of weederplow because morphological characteristics were the main point. Amphibolite and tuff that have densed and undelveloped surface, were used to make weederplow from Amsadong, which is one of the representative remains in alluvion areas and schist that has developed surface, was used to make weederplow from Unseodong, which is one of the representative remains in hilly areas. In case of Amsadong, flake was used to make weederplow and in Unseo case, debris was used as the raw material. These technical differences could be made by method of use depending on geographical conditions, in other words, With or without mounting is the key. Amsadong weederplow from alluvion areas might be used without equipment, but Unseo weederplow might have the purposed to be equipped with wood and it could be shown in the manufacturing process.

영산도는 전남 신안군 흑산면에 속하며 다도해해상국립공원과 신안-다도해 유네스코 생물권보전지역에 포함된다. 세계식물구계 구분에서 중일구계, 온대아구계, 한반도구에 속하며, 한반도 관속식물 분포상 후박나무, 구실잣밤나무, 붉가시나무 등 상록성 식물의 분포한계인 흑산도, 남해안 등 여러 섬이 포함된 남해안아구에 속한다. 현재까지 문헌조사를 통한 영산도에 자생하고 있는 환경부 지정 멸종위기 야생식물은 Ⅰ급 풍란과 Ⅱ급 석곡, 2분류군으로 나타났으나 본 연구를 통해 멸종위기 야생생물 Ⅱ급 혹난초가 자생하는 것으로 밝혀졌다. 섬 중앙부의 문암귀운과 얼굴바위 주변에서 총 4지점, 약 370개체군의 혹난초를 발견하였고, 착생기질과 주요 서식특성 분석을 통해 영산도 혹난초의 서식특성을 파악하였다. 더불어 영산도에 분포하는 멸종위기 야생식물에 대한 전수조사를 통해 기 알려진 풍란 1집단과 석곡 약 1000개체의 분포를 확인하였다. 영산도에 분포하고 있는 멸종위기 야생식물들은 대부분 인간의 접근이 불가능한 절벽사면 등에 분포하고 있어 인위적인 훼손위협은 낮은 것으로 판단되었다. 하지만 섬의 특성상 좁은 면적에 다수의 멸종위기 야생식물이 함께 분포하고 있어서 일부 식물의 자생지가 노출된다면 다수의 멸종위기 야생식물들이 불법적으로 훼손될 가능성이 있는 것으로 나타났으며, 방목염소에 의한 수목피해, 높아지는 귀화식물 점유율 등 환경훼손에 따른 위협은 지속적으로 증대하고 있는 것으로 판단되었다. 이에 따라 멸종위기 야생식물의 지속적인 관리와 모니터링, 섬 전체에 대한 특정도서, 생태경관보호구역 지정 등 정부 차원의 지속적인 관리를 포함한 현지 내· 외를 구분 짓지 않는 적극적인 보전 대책이 필요한 것으로 판단되었다. Yeongsando is an island located in Heuksan-meyon, Sinan-gun, Jeollanam-do, the Republic of Korea, and is part of UNESCO’ s Sinan Dadohae Biosphere Reserve. It belongs to the Sino-Japanese, Temperate Sub-region, the Korean Peninsula Floral Region, and the South Coast Plant Zone which includes islands on South Korea’ s south coast and Heuksan Island, where the evergreen (Machilus thunbergii, Castanopsis sieboldii, and Quercus acuta) distribution limit is according to the vascular plant distribution of the Korean Peninsula. Reviews of literature published to date revealed that Yeongsando’ s naturally growing endangered wild plants listed by the Ministry of Environment belong to two taxa: Neofinetia falcata (Class Ⅰ) and Dendrobium moniliforme (Class Ⅱ). During this study, an additional endangered wild plant Bulbophyllum inconspicum Maxim. (Class Ⅱ) was found. Approximately 370 B. inconspicum Maxim. individuals were found in four locations at the island’s center near Moonamgwiwoon and Face Rock. Their epiphytic disposition and major habitat traits were analyzed. Furthermore, through a complete enumeration of the endangered wild plants on Yeongsando, the distribution of approximately 1,000 individuals of N. falcata and D. moniliforme were confirmed. Endangered wild plants in Yeongsando inhabit cliff walls where the threat of artificial damage is low. Nevertheless, the island is occupied by numerous endangered wild plants in a small area, and the probability of loss of endangered wild plant exists once a partial habitat is exposed. Moreover, environmental threats, such as damage to trees caused by grazing goats and increased occupation of naturalized plants, were expected to continue to grow. Thereby, proactive preservation measures that manage and monitor endangered wild plants and do not differentiate internal/external local regions must be taken while being administered at the government level by designating the entire island as a specific island and an ecological landscape protection area.

F.R.P. Sheets(Carbon, Grass and Aramid) are repairing and rehabilitating materials of which consumption has been increasing steeply most recent. Recently years, in the country, despite of excellent material property, those are used empirically without proving of behavior characteristics. In this test, F.R.P. Sheets(Carbon, Grass and Aramid), were tested for investigation of the change of tensile strength about number of sheet layers and splice lengths. The test results show that the tensile strength do not have any affection with respect to number of sheet layers and fiber sheets, which are cut for using in field, do have adequate spliced length to give the same strength of one sheet.

Direction of Military Readiness Posture against North Korea's Provocations against South Korea

Youngjun Jo(Youngjun Jo) J-INSTITUTE 2022 International Journal of Military Affairs Vol.7 No.2

Purpose: This article recognizes the dangers of North Korea's continued hostilities, including the sinking of the Cheonan, shelling of Yeonpyeong Island, and missile launches, and raises awareness in order for the forces threat-ening national security not to be established in our society. The goal is to have a firm military readiness so that we can fully respond to North Korea's provocations at any time and in any form. Method: In order to analyze North Korea's intentions and threats of provocation toward South Korea, books, academic journals, and dissertations about the provocation toward South Korea were reviewed. Various daily newspapers, news, and government data were studied to recognize the importance of security and derive em-pirical data for establishing military readiness. Results: North Korea has carried out military provocations against South Korea in various forms over the past 70 years despite our efforts to improve relations with the North. Until North Korea gives up its hostile policy toward South Korea and takes tangible military measures, it is the main enemy that threatens our security. We must make a clear distinction between the enemy and the ally. In addition, economic aid to North Korea should be continued while strengthening its nuclear deterrence and inducing change in the North. There should be no war, but it should be prepared to respond immediately if there is. Conclusion: National security is directly related to the survival of the people and is not done by the order of someone. It is important to have the same idea about security, from the leaders of the country, including the president, to all the people. We should keep in mind that national development stems from the people's thorough sense of security and have a security perspective that we protect our country. We should realize the importance of national security and have a firm military preparedness.

Youngjun Yoo(유영준),Daehee Kim(김대희),Inkyung Kim(김인경),Jaekoo Lee(이재구) 한국통신학회 2021 한국통신학회 학술대회논문집 Vol.2021 No.2

Recently, researches have been conducted on domain generalization (DG) to make a robust model against domain-shift. However, they were conducted only on AlexNet and ResNet. In this study, we apply RSC, a state-of-the-art DG technique, to MobileNetV2 to improve DG performance and confirm performance improvement. We obtain the optimal random grayscale ratio by changing several ratios and confirm performance improvement. We visualize features for each image via Grad-CAM to ensure that the model extracts domain invariant features. In future work, we will verify the performance improved by applying the DG technique to models using MobileNetV2 in other tasks.

Supplementary Control of Conventional Coordinated Control for 1000 ㎿ Ultra-supercritical Thermal Power Plant using Dynamic Matrix Control

Youngjun Lee,Euiyeon Yoo,Taehyun Lee,Un-Chul Moon 대한전기학회 2018 Journal of Electrical Engineering & Technology Vol.13 No.1

This paper proposes supplementary control of conventional coordinated control of a power plant which directly affects network frequency. The supplementary control with dynamic matrix control is applied for 1000 ㎿ power plant with ultra-supercritical (USC) once-through boiler. The supplementary control signal is added to the boiler feedforward signal in the existing coordinated control logic. Therefore, it is a very practical structure that can maintain the existing multi-loop control system. This supplementary controller uses the step response model for the power plant system, and on-line optimization is performed at every sampling step. The simulation results demonstrate the effectiveness of the proposed supplementary control in a wide operating range of a practical 1000 ㎿ USC power plant simulator. These results can contribute the stable operation of power system frequency.
