석축형제철로는 한반도 동남부지역에 집중 분포하는 조선후기 제철로의 한 유형으로, 기존에 알려진 제 철로와는 구조와 원료, 송풍방식, 생산품 등에서 차이가 있다. 석축형제철로의 특징은 보강석축으로 인해 반영구적 사용이 가능하다는 점과 토철·사철 등의 분말상 원료를 주로 사용해 탄소과포화상태 분위기의 노에서 선철을 대량으로 생산했다는 점이다. 본고에서는 석축형제철로의 조업방식 규명을 위해 민속·고고·금속학적 분석 자료를 비교검토하였으며, 일부 유적에 대해서는 현장을 직접 답사해 시료를 채취한 후 금속학적 분석을 실시하였다. 그 결과 석축 형제철로의 2차에 걸친 조업방식을 상정할 수 있었다. 1차 조업에서는 토철·사철 등이 저온고체환원법에 의한 환원작용으로 반환원괴가 형성되고, 이 반환원괴를 소재로 한 2차 조업에서는 탄소과포화상태의 노 내 분위기에서 용융선철을 생산한 것으로 추론되었다. 즉 1차 조업은 제련공정에, 2차 조업은 용해정련공 정에 해당된다. 이러한 방식은 기존 원통형·상자형 제철로에서 반환원괴를 생산하던 방법에서 진일보해 토철·사철을 원 료로 선철을 대량생산할 수 있는 획기적인 조업기술로, 제철기술사적으로 큰 변혁의 의미가 내포되어 있 다. 삼국시대∼조선 중기까지 대부분의 제련로는 원통형이었고 조선 후기 일부지역의 상자형로가 알려져 있는데, 이들은 각각 철광석과 사철을 제련해 괴련철과 선철이 혼합된 반환원괴를 생산했던 것으로 이해 된다. 이에 비해 석축형제철로는 현대의 제철기술과 유사한 방식으로 주조철기 제작에 필요한 선철을 대 량생산한 획기적인 기술이라 할 수 있다.

The stone made furnace is a type of furnace in Choseon era as the iron mines around Ulsan Dalcheon distributed in the southeastern part of the Korean, such as cylinder type-Box type Iron Manufacture Furnace to the known material and the structure of the furnace, ventilation system, a lot of products, etc. there is a difference. This paper were compared for investigate how archaeological and folk and metal analyzes to working the stone made furnace. Accordingly, bring in working as two step, primary working step : reduction in temperature iron soil and iron sand solid reducing action is returned up the tangled with the previous state of the raw materials and steel generate, secondary working step : supersaturation of carbon in the atmosphere of the furnace hot metal is formed, then the prepared through outflow mould (based Iron lump Edition) flowed in the pig iron production. That is primary working step corresponds to the smelting process, secondary working step corresponds to the dissolved melting process. This workin method is innovation at technical history since existing reduction in cylindrical type and box type iron masses in the form of a mixture, return proto-reduction lump step forward in the way it was produced, Iron soil. Seasons pig iron as raw materials can be produced in large quantities.

On April 23, 2024, the Hwaseong temporary palace, which had been dismantled during the Japanese colonial period, was fully restored to its original form after 119 years. The restoration process involved nine stages of excavation, alongside extensive research in historical documentation, architectural studies, and the preservation and utilization of cultural heritage. However, despite the structure’s prominence with 576 compartments, research on the roof tiles, particularly the roof-end tiles that both protect structural elements and symbolize the grandeur of the Hwaseong temporary palace, remains limited. Prior studies have also failed to clearly address the production period or the evolution of these tiles. This study analyzes roof-end tiles unearthed from Hwaseong temporary palace, focusing on their characteristics, production period, and historical background. It was found that the features of the roof-end tiles from Hwaseong temporary palace closely align with those from palaces and royal tombs constructed or renovated between the 16th and 18th centuries. These stylistic similarities extend to the roof-end tiles used during the late 18th-century construction of Hwaseong temporary palace. The study draws on the 『Hwaseong Seongyeok Uigwe』(Records of Hwaseong Fortress Construction) to investigate why the roof-end tiles of Hwaseong temporary palace were made using central construction techniques. By analyzing the occupations, origins, and names of artisans listed in the 『Hwaseong Seongyeok Uigwe』, and cross-referencing them with artisans mentioned in 18th-century construction records, it was confirmed that many of the craftsmen were independent artisans from Seoul. These artisans appeared repeatedly in documents such as the 『Jangjo Yeonguwon Myosodogam Uigwe』(1762), 『Yeongjo Wonreung Sanneungdogam Uigwe』(1776), 『Gyeongmogung Gaegundogam Uigwe』(1776), and 『Munhyo Sejabin Gonghongundogam Uigwe』(1786). After the dissolution of state-run handicraft systems following the Imjin War(Japanese Invasions of Korea, 1592~1598), many government-affiliated artisans dispersed but continued to participate in the production of roof tiles for palaces, royal tombs, Confucian shrines, and temporary palace. Their involvement in the construction of Hwaseong temporary palace explains the direct transfer of central tile-making techniques and styles to the site. This research establishes the production period of the roof-end tiles at Hwaseong temporary palace, identifying them as products of the initial construction phase. It further elucidates the characteristics of roof-end tiles during the post-Imjin War period to the pre-reconstruction of Gyeongbokgung, a previously under-researched era in the evolution of Joseon-era roof tiles. Additionally, it sheds light on the operational scope of tile-making artisans of the time. These findings are expected to contribute significantly to future restoration efforts of Hwaseong temporary palace and the five major palaces in Seoul.

고려시대 평기와는 선행 연구를 통해 문양 및 제작기법에 관한 성격이 어느 정도 규명되었다. 그러나 세부적인 속성과 이들의 변화시점에 대해서 이견이 있는데, 검토된 자료가 주로 수량이 부족한 연호명 기와 및 층위적으로 불안정한 건물지 출토품이기 때문에 야기된 문제로 생각된다. 이에 본고에서는 층위적으로 안정적인 가마에서 출토된 자료에 한정하여 살펴보았다. 기와의 제작연대는 가마의 14C와 고고지자기연대측정 결과를 수용하였는데, 두 방법의 측정연대와 기존의 고고학적 성과를 상호 검토하여 절대연대의 활용이 가능하다는 것을 검증하였다. 이를 토대로 검토한 결과 평기와 문양과 윤철흔은 시간성을 반영한다는 기존 견해에 재고가 필요하며, 수키와 종류와 하단부 조정방법은 과도기가 긴 속성임을 알 수 있었다. 비슷한 형태의 문양이 각기 다른 유적에서 확인된 것은 와공이 소비지로 이동할 때 제작도구는 현지에서 조달하였을 가능성과 복수의 가마에서 한 곳의 수요지로 공급되었을 가능성을 검토하였다. 또한 방대한 종류의 문양과 기와 제작기술이 변화되는 과도기가 길고, 지역적으로 변화시기가 상이한 점을 통해 고려사회의 기와생산과 공급에 대한 통제는 세부적인 제작기법까지 미치지 않은 것으로 보인다.

Previous studies have illuminated the patterns and production method of the Korea dynasty plain roof-tiles. In contrast, debates about the detailed properties and their change point in time remain unsettled. This is partly due to the limitation in data, where the majority come from buildings with unclear stratigraphy. This paper examines the production features of the plain roof-tiles from kilns, where the artifact dates (stratigraphy) are relatively clear. This study uses AMS and archaeomagnetic dates of the kilns for examining roof-tile production dates. Through comparing the two dating methods and existing archaeological results, the possibility of using absolute dates for research like this was substantiated. The results show that the argument that the patterns and the wheel-shaped marks (Yoonchul-heun; a trace made by binding something around the tile) on plain roof-tiles reflect the production dates need to be revisited, and that the typological changes in convex roof-tiles and the changes in the modification methods in bottom-part go through a long transitional period. Similar patterns on roof-tiles are found across different sites. This possibly indicates that when a roof-tile producer was sent to a certain consumption region, the producer used the production equipment from the dispatched region, and that a single consumption region received the roof-tiles from multiple kiln sites. Based on the wide range of variation in the patterns on plain roof-tiles and the long transitional period for the changes in roof-tile production methods, it can be inferred that the control system of the roof-tile production and distribution of Korea Dynasty (918-1392 CE) did not reach the details of production methods.

The LRA(Logistic Regression Analysis) conducts a quantitative analysis by collecting a lot of samples and the AHP(Analytic Hierarchy Program) makes use of expert decision influenced by subjective judgment to a certain degree. This study is to suggest a combination method in mapping landslide hazard by giving equal weight for the result of LRA and AHP. Topographic factors(slope, aspect, elevation), soil dram, soil depth and land use were adopted to classify landslide hazard areas. The three methods(LRA, AHP, the combined approach) was applied to a $520km^2$ region located in the middle of South Korea which have occurred 39 landslides during 1999 and 2003. The suggested method showed 58.9% matching rate for the real landslide sites comparing with the classified areas of high-risk landslide While LRA and AHP Showed 46.1% and 48.7% matching rates respectively. Further studies are recommended to find the optimal combining weight of LRA and AHP with more landslide data.

This paper reviews the traditional practice of Klila production, its microbiological, physicochemical and nutritional properties and aims to raise awareness of Klila. The main objective of this review is to highlight the typicality of Klila and to propose a form of labelling that could help promote it. The Klila is a traditional extra hard cheese from southern Algeria. Nomadic tribes produce it from goat, sheep, or cow milk. Curdled milk is obtained by spontaneous fermentation. It is churned to recover the butter. The co-product, a sour, fat-free milk: Lben, undergoes a moderate heat treatment to get a fresh cheese which, after a dehydration process, gives the Klila. The chemical composition of this product varies regarding fat content. It has a very low water content (less than 10%) and comes in very hard pieces of varying size and irregular shape. The dry matter, for instance, can vary from 33 to 95%. Water availability (Aw) varies from 0.32 to 0.467. Fat rate can vary a lot from region to region from 9.5 to 29.3?g/100?g of cheese. The protein rate also varies a lot: between 29.9 and 71.4?g/100?g of cheese. The lactose concentration can range within 1.2 to 2.4?g/100?mL. The microbiological quality of Klila depends mainly on the quality of the raw milk used and all hygienic factors that surround milk production. The physicochemical conditions that prevail inside Klila are not favourable for the microbial growth. The Klila is an example of adaptation of the nomads’ lifestyle in the Algerian Sahara who use it as a culinary adjunct for nutritional and therapeutic purposes. The Klila can be grinded to be put as ingredient in “Zrizri” dessert with dates and clarified butter (smen). Some people prefer to consume fresh Klila with dates and green tea.

In the era of the fourth industrial revolution, many production plants are gradually evolving into smart factories that apply information and communication technology to manufacturing, distribution, production, and quality management. The conversion from conventional factories to smart factories has resulted in the automation of production sites using the internet and the internet of things (IoT) technology. Thus, labor-intensive production can easily collect necessary information. However, implementing a smart factory required a significant amount of time, effort, and money. In particular, labor-intensive production industries are not automated, and productivity is determined by human skill. A representative industry of such industries is sewing the industry. In the sewing industry, wherein productivity is determined by the operator's skills. This study suggests that production performance, inventory management and product delivery of the sewing industries can be managed efficiently with existing production method by using smart buttons incorporating IoT functions, without using automated machinery.

This study designed a model of the efficient production schemes and raw materials transportation optimization of current South Korean’s simple and monolithic distribution system of wood to build a SCM (supply chain management) as a basic level to establish a distribution of future by pellet production of raw materials costs and reduce transport costs, and specifically to forest of pallet to contribute to revitalizing the market. The result of each transportation costs after building the best transportation network from raw material supply area to demand area applying transport law was 964,600 thousands Won from 6 supply areas to 7 demand areas. And the result of each model’s analysis to get the pellet’s efficient production through production cost reduction showed that it reduced from 325,701 Won/t to 240,106 Won/t, results of existing efficient pellet for the production model 8,233 tons over 20,000 tons annual production capacity from the size of the expanded production capacity when the expansion. However, when the production size expanded to 50,000 Tons of the production, the effect was very small even though production cost decreased.

Sperm treatment methods affect sperm fertility and developmental potential of in vitro fertilized(IVF) embryos. Confirmation of the developmental rate according to the information of donor cow will be helpful for the production of elite Jeju Black Cattle(JBC) embryos. To optimize the suitable JBC sperm treatment method, the following methods of percoll gradient, triladyl and percoll-triladyl combination(P, T and PT, respectively) were used to sperm treatment. At 2 days after IVF, there was no difference in the fertilization rate among all groups. The cleavage rate at day 4 was higher in PT and T groups than in P group. The blastocyst formation rate at day 8 was significantly increased in T and PT groups(p<0.05). In comparison of the in vitro development potential of donor and non-donor cows, there were no differences from IVF rate to blastocyst formation rate. According to JBC grade(1++, 1+, 1, 2), the development rate was the highest in 1++ grade cattle, followed by 1, 1+ and 2 grade. Also, in vitro developmental potential by carcass weight was the highest at the 300~350 kg, followed by 300 kg or less, 350~400 kg, and then 400 kg more over. While the T method can collect a small amount of viable sperm, the P method was present a little toxic to JBC sperm. Thus, we developed PT method combined two sperm treatment methods. In this study, the development of IVF embryos was more effective when the carcass grade was high and the carcass weight was about 350 kg. This result demonstrates that JBC sperm can be effectively recovered with simple and efficient PT method and using this technique, elite JBC IVF embryos can be produced in vitro for the mass production of JBC.

Background/Objectives: This study aims to investigate the feasibility of undertaking an economic evaluation of different solvents in the production of LaCoO3 NPs prepared by the co-precipitation method. Methods/Statistical analysis: Several economic evaluation parameters were calculated in an ideal condition. Findings: The result showed that the production of LaCoO3 NPs is prospective to be carried out for more than 20 years. The GPM, PBP, CNPV/TIC, and PI showed positive while BEP, BEC, ROI, and IRR were negative. The NPs with aquadest solvent were better than ethanol and ethylene glycol. To confirm its feasibility, these calculations were varied by changing raw materials-sales and income tax costs. Changing raw materials-sales confirmed that the NPs with aquadest can maintain the GPM for increasing raw material up to 300% and decreasing sales up to -100%. The NPs with aquadest and ethanol solvents can survive up to 75% of increasing income tax while ethylene glycol is only less than 50%. Improvements/Applications: This study is very useful for predicting the feasibility in carrying out a project that produces LaCoO3 NPs.

21세기는 정보 지향과 정보 의존이 심화되는 지식 기반 사회로 변화하고 있다. 뉴미디어 시대의 방송은 방송과 통신의 융합이 보편화되어 새로운 형태의 방송 서비스가 가능해짐에 따라 수용자의 요구를 충족시키는 소비자 중심의 서비스 형태로 변화되고 있다. 단방향 송신만 하던 기존 방송과 달리 양방향 커뮤니케이션이 가능한 퍼스널 미디어 시대가 등장한 것이다. 그 결과 새로운 복합매체들이 상용화 되었지만 대표적인 경우가 DMB이다. DMB는 나만의 TV 혹은 내손안의 TV라고 말한다. 하지만 콘텐츠 측면으로는 기존 방송의 재전송이라는 한계를 드러내고 있다. 향후의 DMB 방송은 재전송에서 벗어나 그 특성에 맞는 콘텐츠로 제작되어야만 할 것이다. DMB 콘텐츠의 제작방향을 정립하기 위해서는 먼저 DMB라는 매체의 특성 및 서비스의 영역을 정확하게 분석하는 것이 필요하다. 본 연구는 이러한 분석을 통해 DMB에 적합한 프로그램 개발과 적정한 시간, 카메라 앵글과 워킹 등의 시각적 표현방법 등 전반적인 영상콘텐츠의 최적화된 제작기법에 대해 제안하고자 한다. DMB의 특성에 맞게 제작된 콘텐츠는 수용자들로 하여금 더욱 친숙하게 느끼게 할 것이며 나아가 새로운 시청 문화로까지 자리 잡을 것으로 기대한다.

The 21st century has been changed into a knowledge-oriented society, which means our society is more dependent on information and moves toward information. The mixing of broadcasting and co mmunication prevails and it makes possible a new type of broadcasting service. Depending on that, a broadcasting is being changed into a consumer-oriented service to satisfy the demands of consum ers in a new media age. It makes us attain to the personal media age to be possible interactive com munication unlike existing one-way transmission. As a result, new complex media are commercialize d and the instance is DMB. DMB is said 'my own TV' or 'TV in my own hands'. But it has limit t o retransmit existing broadcast programs. So hereafter, DMB broadcasting must be produced with co ntents suited its properties out of retransmitting existing contents. It is necessary to analyze exactly properties and service fields of DMB media to make an establish production direction of contents for DMB. This paper intends to suggest overall optimized image-contents production direction including appropriate program developments, a proper running time, visual expressions such as a camera angle and walking etc... DMB contents suited with its properties will give more familiarities to DMB users. Besides, DMB is expected to be a new culture watching broadcasting.

본고에서는 연구문제로 (1) 2D 영상물을 바탕으로 3D 입체영상저작물을 제작할 때, 제작된 방법에 따라 저작된 3D의 영상 저작물이 2D 영상 저작물과는 별도로 2차적 저작물로서 저작권을 인정받을 수 있을지에 대하여 논의 하였다. (2) 또한 3D 입체영상 저작물이 2차적 저작물로서 인정될 경우 저작권의 귀속과 2차적 저작물 작성권의 귀속에 관해 알아보았다. 현재의 저작권법에서 3D 입체영상저작물이 2차적 저작물로서 저작권을 인정받기 위해서는 2D 영상물을 바탕으로 제작자의 '창작성'이 가미될 수 있는 컴퓨터 그래픽을 이용한 3D 변환 작업을 통해 제작된 3D 입체 영상물의 경우만 2차적 저작물로서 인정받을 수 있을 것이다. 또한 현재의 저작권법에서는 이미 한 방송사에서 방송된 2D 영상 저작물을 제3의 방송사에 3D 입체 영상물로 납품하였다면, 저작권의 귀속이 최초 제작사에 있다고 하여도 영상물의 '이용허락'의 범위를 계약으로 설정하지 않는 한 '침해' 혹은 '불법 사용'의 결론에 도달할 것으로 보여 진다. 이는 3D 입체영상물이 2D의 영상물과 별개로 2차적 저작물로서 인정을 받을 수 있다면 저작권의 귀속 문제가 달라질 수 있다.

In this study, a model integration method is pressented as a new method for development of a parametric simulation model. This method enable us to integrate the special simulation models for each production subsystem into a large simulation model. Not only this large simulation model but also each special simulation model for each production subsytem can be used independently. Using this integration method man can reduce the development time and cost for simulation model development. To show the usefulness of this method, a simulation model for a production system with robots is developed by this model integration method. This simulation model is realized by the integration of two special simulation models, one model for a machining subsystem and the other model for a transport subsystem. The modeled production system consists of the robotic cells for machining and a transport subsystem which enable the material flow among the robotic cells. The flow of workpiece in each robotic cell is not fixed. All machines in a robotic cell are only served by robots.

Korean traditional Sikhye is made from rice and malt, and It's main product Is maltose. However commercial Sikhye differs from traditional Sikhye because it's main component is sucrose. Sikhye industry faces many problems such as contamination of malt with microorganisms, low amylase activity of malt and technical difficulties. There is no commercial Sikhye which is only using rice and malt by these reasons. To produce the traditional Sikhye free from these problems, it is necessary to restrict the microorganisms of malt and to standardize the amylase activity of malt. In addition, the Introduction of effective control and sanitaric process is required. In Sikhye production. if $\beta$-amylase and isoamylase or pullulanase were added, starch could be saccharified 100% as maltose. Accordingly, this method brings us the low cost of Sikhye.

기존의 GrabCut 알고리즘은 자동 객체 추출이 아닌 사용자가 객체 영역에 사각형 윈도우를 설정해야하는 알고리즘이다. 본 논문에서는 자동 시스템으로 변환하기 위해 인간의 시각 시스템을 기반으로 영상에서 가장 눈에 띄는 영역을 탐지하는 방법을 연구하였다. 주의 시각 영역인 Saliency Map을 생성하기 위해서 인간이 색채를 감지하는 ‘적/녹’ ‘황/청’의 대립색설을 기반으로 하는 Lab 색공간을 이용하여 생성한다. 생성된 Saliency Map을 주파수 공간으로 변환하여 저주파 영역에 국부적인 경계를 나타내고 경계를 탐지해내어 Saliency Point를 생성한다. 이렇게 생성된 Saliency Point의 좌표 값을 이용하여 윈도우를 자동으로 생성한 후 GrabCut 알고리즘을 기반으로 객체를 추출하였다. 다양한 영상에 제안한 알고리즘을 적용한 결과 객체 영역에 자동으로 윈도우가 생성되었고 객체가 추출되었다.

Conventional GrabCut algorithm is semi-automatic algorithm that user must be set rectangle window surrounds the object. This paper studied automatic object detection to solve these problem by detecting salient region based on Human Visual System. Saliency map is computed using Lab color space which is based on color opposing theory of 'red-green' and 'blue-yellow'. Then Saliency Points are computed from the boundaries of Low-Frequency region that are extracted from Saliency Map. Finally, Rectangle windows are obtained from coordinate value of Saliency Points and these windows are used in GrabCut algorithm to extract objects. Through various experiments, the proposed algorithm computing rectangle windows of salient region and extracting objects has been proved
