This study proposes the desirable direction of urban planning strategy for revitalization of the existing commercial area. the direction is drawn through the analysis of present land use of the commercial area in Jung-gu, Dong-gu, Juan, and Guwol Center of City, the one of Three Cores presented in ‘The Comprehensive Urban Planning of Incheon, 2020’. Land categories, height of building, and floor area ratio(FAR) are used as data of the analysis. The first result of analysis shows that the Comprehensive urban planning of Incheon from 2001 to 2020 has modified by the short-term change of circumstances in step with urban development momentarily without long-term goal. Second, the use of FAR is too inefficient as the average FAR of the business area is more less than legal one. The last one, the average FAR and the frequency of high-rise building tends to increase in the order of location, Jung-gu, Dong-gu, Juan, and Guwol. The fact shows not only that the extensive expansion causes decentralization, but also that each district has such different regional and social peculiarities that it cannot be a group of center of city. Based on these results, we propose the direction of urban management planning like followings: the necessity of breaking away from stiffness of Euclidena Zoning, applying flexible urban planning for revitalization, and high-density mixed use development of the commercial area.

진성이씨 이동표가의 언간 현황과 서체적 특징

정복동(Jeong, Bok-dong) 한국서예학회 2012 서예학연구 Vol.21 No.1

본고는 17세기 후반 숙종 시기의 문신인 나은 李東標(1644(인조22)-1700(숙종 26))가의 언간 서체를 통해 그의 언간 서체와 언간의 문장 구성 형식을 고찰하였다. 이동표가의 언간은 총 37건으로 그의 어머니에게 보낸 언간이 주를 이루며, 삼촌 이명익의 언간이 1건 있다. 필사된 시기는 1644-1700년이다. 언간에는 당시의 생활상과 과거제도에 관한 자료, 친모와 서모에 대한 상대경어법 사용의 차이점, 수신자에 따라 각각 다른 감성으로 표현한 서풍 등이 담겨있어서 언간의 형식뿐만 아니라 국어사·문화사 및 서예사 자료로도 그 가치가 높다. 언간의 형식은 언간을 받는 대상에 대한 경의를 나타내기 위하여 대두법을 적용하였다. 친모에게 쓴 언간은 이항식과 極行式으로 경의와 존경을 나타냈으며, 서모에게 쓴 언간은 隔間法의 차별화된 대두법이 적용되었다. 그러므로 친모와 서모에게 쓴 언간 두 편을 주 대상으로 삼아 언간의 문장 구성형식과 문자의 구조를 분석하는데 목적을 두었다. 아울러 동일한 연결문자를 비교하여 시대적으로 서체가 변화된 특징을 파악하였다. 두 언간을 중심으로 문자의 구조를 비교 분석한 결과 단일문자의 자모는 두 언간 모두 대부분 가획으로 연속성을 드러낸 흘림체로 규정하였다. 특히 2-5음절 어절의 연결문자를 분석한 결과 친모에게 보낸 언간보다 서모에게 보낸 언간의 연결 정도가 30%가량 많으며, 서모에게 보낸 언간의 연결정도는 거의 80%나 된다. 이는 친모에 대한 존경하는 마음이 心手相應된 것으로 보인다. 초중성 합자와 초중종성 합자의 구조에서 서체의 특징은 서모에게 보낸 언간이 친모에게 보낸 언간보다 원필세가 많은 斜形 결구이며, 친모의 언간이 平形 결구로서 古雅한 意取를 보인다. 또한 ｢훈민정음해례본｣의 점획이 모음 ‘ㅜ’에 나타나고, 종성 ‘ㄹ’을 일필서로 직선화하였으며, 횡모음을 짧게 절제하여 결자 한 것 등은 한자 행초서의 영향을 받은 것으로, 한글 서체의 형성이 한자의 필의와 무관하지 않음을 확인할 수 있었다. 그리고 동일한 어절의 연결된 문자를 비교 분석한 결과 1670년대보다 1680년대 이후의 서풍이 더욱 맑고 견강하게 정제되었다. 이동표의 독창적인 한글 흘림체는 17세기 후반 사대부가에 유행한 행초서의 연면체 서풍에서 어느 정도 영향을 받았고, 선조들로부터 계승되어온 가풍과 학풍을 연마하여 자신만의 淸勁高逸한 한글서체를 완성한 것으로 보인다. 이는 한글서예사에서 18세기 이후 완성될 궁체와 추사체 형성을 예견할 수 있는 서체라고 할 수 있다. In this paper are treated the type of Korean letters and how to build their sentence from the family of Naeun Lee Dong-pyo (李東標; 1644 (the 22nd year of King Injo government)-1700 (the 26th year of King Sukjong government)) who served as a civil minister in the late 17th century of Chosun Dynasty. The total number of Lee Dong-pyo family's letters is 37, most of which were written by Lee Dong-pyo to his mother and one by his uncle Lee Myeong-ik. These letters are assumed to be written during 1644-1700. From the Korean letters, we could find the living conditions at that time, the documents for civil service examination, and the use of different honorific expressions for his mother and his father's concubine, and various styles of calligraphy, which are all highly valued as references for studying the history of Korean language, culture and calligraphy. In the form of the Korean letters, Daedu (leaving a blank before the name of a receiver in order to show the sender's respect for the receiver) is applied, and this method is differently used between the letters for his mother (placing a first letter on the top line of the next sentence to show respect) and the letters for his father's concubine (leaving one or two blank before letter to show respect). Two Korean letters received by his mother and his father's concubine are mainly selected for analysis of the formality of making sentences and the structure of characters. Along with it, connected characters are compared to understand the change of the style of handwriting over time. The result of the comparison of the two Korean letters for the structure of characters shows that the Korean alphabet of a single letter uses Heullim style, which has the continuity of creating a new letter by adding stroke in both of them. In particular, from the analysis of connected letters of 2-5 syllables, it could be found that the degree of connectivity of Korean letters sent to his father's concubine is about 30% higher than for his mother, and in total the degree is up to 80% for his father's concubine, which seems that more respect for his mother is naturally expressed through mind drawing. In the calligraphic features of a letter combined by initial consonant and vowel and one of initial consonant, vowel and final consonant, the Korean letters to his father's concubine show more tilt type, compared with those for his mother, while the Korean letters for his mother revealing some elegance. In addition, all the dots and strokes in HunMinJeongEumHaeRyeBon are expressed at the vowel ‘ㅜ’, and the final consonant ‘ㄹ’ is expressed as the form of straight line and horizontal vowels are intentionally shortened, which all indicates the formality of the Korean letters is influenced by the Chinese Haengseo and Choseo calligraphic styles. And the analysis of connected letters of the same Eojeol (generally a word) shows that his calligraphic style of the late 1680 has something clearer, stronger and more refined than that in 1670. Lee Dong-pyo's peculiar Hangul Heullim style is a little affected by Yeonmyeon style which was popular among Confucian scholars in the late 17th century and he learned hard his family tradition and academic one and made his own Hangul style. This may be a precursor of Gung style and Chusa style which both will be completed in the late 18th century.

A Study on Recent Credit Loan from Households in South Korea

Jeong,Dong-Bin 한국유통과학회 2019 KODISA ICBE (International Conference on Business Vol.2019 No.-

In this paper, we examine a causal relationship between a response variable credit loan from households and several explanatory variables such as interest of certificate of deposit (CD) and loan collateralized with housing and so on. Based on 31 observations sampled from the 4th quarter in 2008 to the 4th quarter in 2016, the optimal forecasts can be obtained and expected to apply to the distribution area comprehensively. In order to accomplish the objectives, both the multiple regression model with correlated errors and several exponential smoothing methods are, in main, analyzed by using IBM SPSS 23.0. A number of goodness-of-fit statistics, at the same time, are also exploited as a tool of optimal model-building.

Lightweight Printed Dipole Antenna Array With 3×2 Beamforming Network for Wide UAV Communication Coverage

Dong‑Geun Seo,Jeong‑Soo Park,Gun ‑Ki Lee,Wang‑Sang Lee 대한전기학회 2020 Journal of Electrical Engineering & Technology Vol.15 No.4

In this paper, a lightweight printed dipole antenna array with 3×2 beamforming network for wide unmanned aerial vehicle (UAV) communication coverage is presented. The proposed antenna consists of an upper substrate, a lower substrate, and two supports with a microstrip feeding. The upper substrate has a two-element printed dipole antenna array, and the lower substrate includes a beamforming feeding circuit and a ground plane as a refector of the proposed antenna array for gain improvement. For wide beam coverage, the proposed feeding network consists of three RF switches, one Wilkinson power divider, and one 90° hybrid coupler, and generates the wide beam using one broadside beam and two end-fre beams. Measured impedance bandwidth, peak gain, and half-power beamwidth (HPBW) of the proposed array operated from 5.03 to 5.15 GHz are approximately 2 GHz, 4.3 dBi, and 155°, respectively.

Improvement of interlaminar properties of carbon fiber‑reinforced epoxy composites using aluminum trihydroxide

Dong‑Jun Kwon,Sung‑Min Park,Il‑Jun Kwon,Joung‑Man Park,Euigyung Jeong 한국탄소학회 2019 Carbon Letters Vol.29 No.2

This study provides an economical and effective method to improve the interlaminar properties of carbon fiber-reinforced polymers (CFRPs) using aluminum trihydroxide (ATH) microparticles. ATH microparticles are cheap and are expected to show good affinity to epoxies in the matrix and sizing agents of the carbon fibers owing to the presence of three hydroxyl groups. In addition, ATH particles are reported to improve the mechanical properties of polymers when used as the reinforcement. In this study, ATH microparticles of various sizes, 1.5, 10, and 20 μm, were used to improve the interlaminar properties of the CFRPs. ATH particles with a size of 1.5 μm improved the tensile properties of the ATH/epoxy resin and did not significantly alter the curing behavior. The interfacial adhesion between the carbon fiber and the epoxy resin was also improved, and the impregnation of the resin mixture remained similar to that of the neat resin, resulting in no significant void and defect formation. Considering the above results, the resulting 1.5 μm ATH-reinforced CFRP showed improved interlaminar properties compared to CFRP without ATH. However, 10 and 20 μm ATH-reinforced CFRPs showed deteriorated interlaminar properties due to the diminished tensile properties of the resin itself and resin impregnation, which resulted in more voids and defects, despite the interfacial adhesion between the fiber and the matrix resin.

Association between business switch or liquidation, and the demographics of Small and Medium Enterprises in South Korea

Dong‑Bin Jeong 한국유통과학회 2018 The Journal of Industrial Distribution & Business( Vol.9 No.9

Purpose – In this study, we consider and examine relationships between reasons for business switch or liquidation (BSL), and the demographics of small and medium enterprises (SMEs) in South Korea. The related five variables are occupations, administrative districts, age of employer, firm age and foundation motivation. In addition, eleven levels in association with reasons for BSL visualize the corresponding demographics by measuring their similarity on the dimensional planes assuming that the association exists between variables under consideration. Research design, data, and methodology - This study is done by the Ministry of SMEs and Startups in 2016 and examines 20,307 small and medium enterprises. For examining the distinct relationships among variables under consideration, both chi-squared test and correspondence analysis as main statistical tools are used. Results - The results show that among levels of reasons for BSL the three levels –weakening profitability, poor sales and economic depression- are main ones for the five demographics variables mentioned above, and we can obtain the detailed associations between attributes of corresponding variables by inspecting the two dimensional plane. Conclusions - This study suggests reasons for BSL are closely associated with the five different demographics variables – Administrative districts, Firm age, Occupations, Age of employer and Foundation motivation-by looking over results.

A Review on Sales on Large-scale Retailing Types in South Korea

Jeong,Dong-Bin 한국유통과학회 2019 KODISA ICBE (International Conference on Business Vol.2019 No.-

In this work, we investigate several time series models to forecast of sales at department stores and at discount stores in South Korea. Considering two large-scale retailing types are homogeneous and comparable in size based on 86 realizations taken from January in 2010 to February in 2017. The dataset of this work is got from Korean Statistical Information Service (KOSIS) and Survey of Service Trend of Korea Statistical Administration, and we exploit the procedures of IBM SPSS 23.0 such as TSPLOT, TSMODEL, EXSMOOTH, ARIMA and MODELFIT. Several model-fit measures, simultaneously, are also used as criteria of the optimal model construction. Time series models can not only predict future sales but can account for economic or business mechanism and increase our understanding of relationships among phenomena or variables under consideration.
