온라인 쇼핑 시장의 발전과 코로나19 바이러스의 확산으로 비대면 생활 시대가 점진되면서 라스트 마일 시장(Last Mile Market)은 유래 없는 호황을 맞이하고 있다. 이제는 배송의 대상이 음식에 국한되지 않고 편의점, H&B 스토어 등 비(非)음식분야까지 서비스가 보편화 되었다. 본 연구는 라스트 마일 업계에서 IT(Information Technology) 기술력을 기반으로 성공적인 성장을 거듭하고 있는 메쉬코리아의 성공 사례를 자원기반이론(RBV)의 확장 모델로 평가되는 SER-M 패러다임을 통해 분석했다. 주체의 특성, 환경적 조건, 자원의 역량요인 등이 융합 · 결합을 통해 어떠한 메커니즘을 형성하여 성공할 수 있었는지, 그리고 더 큰 성장을 위해 어떤 도전과제에 직면하고 있는지를 살펴보았다. 분석결과, 선순환적 성장 메커니즘을 구축시켜준 주요 원동력은 다음과 같이 나타났다. 첫째, 주체변수의 특성은 창업가의 기업가정신으로 나타났다. 메쉬코리아의 창업주 유정범 대표는 아버지의 장례식장에서 배달 시스템의 비효율성을 보면서 이를 개선하기 위해 창업을 결심했다. 유대표의 기업가 정신은 현장 중시 철학인 ‘우문현답’, 모두에게 이익이 되도록 하려는 모토인 ‘세상에서 가장 깨끗한 1원의 가치’, 그리고 흔히 라이더(Rider)라 부르는 배송기사들에 대한 ‘섬김의 리더십’실천으로 부각된다. 둘째, 성공을 위한 환경적 요인은 온라인 쇼핑이 활성화되어 라스트 마일 사업이 확대된 시장 환경, 인공지능(AI), 빅데이터 등 다양한 기술의 발전에 힘입어 신유통 등 물류 시장에 혁신의 바람을 불게 한 시대적 환경, 그리고 코로나-19 신종 바이러스 확산에 따른 강력한 사회적 거리두기 조치등의 정책적 환경이 새로운 기회를 제공한 것으로 나타났다. 셋째, 유정범 대표의 기업가 정신과 코로나 팬데믹 환경에 더하여 메쉬코리아가 보유하고 있는 인적, 물적 자원을 업계에서 유일하게 직영 구조로 운영하는 전략적 자원으로 구축 및 활용함으로써 글로벌 배송 업체까지도 벤치마킹하고자 하는 메쉬코리아의 선순환적 성공 메커니즘이 사내외로 확산되고 있음을 확인하였다. 논문의 마지막 부분에서는 대부분의 사업과 산업이 어려움에 처한 상황에서도 배송업계에 대한 낙관적 전망에 따라 포화상태로 접어들고 있는 라스트 마일 업계에서 메쉬코리아가 향후 직면하게 될 도전과제에 대하여 살펴보았다. 본 연구는 메쉬코리아의 성공적 성장사례를 통해 스타트업 기업들의 시장진입 및 성장전략, 그리고 그 과정에서 직면하게 되는 이슈와 과제를 어떻게 대응하고 극복해 갈 것인지에 대한 방법을 토론하는 데 그 의미를 두고자 하였다. The Last Mile Market is experiencing an unprecedented boom due to advent of the non-faceto-face life era caused by the development of the online shoppong market and the spread of the COVID-19. The target of delivery is not limited to food, and services have become common in non-food fields such as convenience stores and H&B stores. This study analyzed the success cases of Mesh Korea, which has achieved successful results based on IT(Information Technology) in the Last Mile Industry, through a ser-M model. and this study examines what kind of mechanisms the subject, environment, and resourse factors could have formed and succeeded through fusion and combination, and what challenges they face for greater growth. CEO Rhyu Jeong-beom, founder of Mesh Korea, decided to start a business in order to improve the inefficiency of the delivery system at his father’s funeral. His entrepreneurship is “Woo Moon Hyeon-dap(The answer to our problem is in the field),” a philosophy that focuses on the field, “the cleanest value of 1 won in the world,” and the leadership of serving delivery riders. Environmental factors for success were analyzed by dividing in to Market Environment in which the Last Mile Market has expanded due to active online shopping, The environment of the times in which various technologies such as AI(artificial intelligence) and big data have been developed to blow the wind of innovation in the logistics market. and Policy Environment such as strong social distancing following the spread of the COVID-19. This study presents the challenges that Mesh Korea will face in the future in the last mile industry, which is saturated with indyustry optimism. And it is meaningful in discussing how to overcome the start-up and growth of start-up companies and the challenges they will face through the case of Mesh Korea.

WHAT MAKES A GOOD TAX SYSTEM : TOWARD A BETTER UNDERSTANDING OF TAX REFORM

Rhyu, Ji-Sung 단국대학교 정책과학연구소 1992 정책과학연구 Vol.4 No.-

우리는 政府가 社會를 위해 보다 많은 일들을 하기를 바라지만, 그 비용을 추렴하는 행위에는 너나없이 인색하다. 이웃이 내는 稅金은 사회를 위해 좋은 돈이고 자신에게 책정된 세액을 불공정하다는 느낌은 누구나 갖고 있는 듯 하다. 따라서 정부가 公共事業을 얼마나 效率的으로 집행하는가하는 문제도 중요하지만, 정부가 공공사업을 위해 얼마나 공정히 각 개인에게 세액을 책정하는가하는 문제 역시 상당히 중요하다. 그러나, 한 국가의 租稅制度는 그 國家의 目標, 政治的, 經濟的 條件, 그리고 社會的, 文化的 與件 등에 따라 큰 차이를 보임으로 일률적으로 특정한 형태의 세제가 가장 합리적이라고 단정하기는 어렵다. 이는 곧, 한 사회의 조세제도를 가장 잘 설명하고 분석하기 위해서, 몇 가지 중요한 변수들의 相關關係만을 설명할 수 있는 특정 조세이론에 의존하기보다는 한 사회세제의 총체적인 (특정사회의 경제, 정치, 및 문화 등) 설명을 통한 이해가 더욱 적실성이 있다는 얘기다. 이러한 맥락에서, 이 글에서는 (1) 租稅의 公平性問題와 (2)租稅政策과 經濟活性化 및 經濟發展과의 關係를 한 국가의 총체적 맥락에서 설명하고자 했다. 이 글에서는, 먼저 조세의 개념, 정의, 및 용어들이 이 분야에서 쓰이는 의미를 간략히 소개하고 있고, 이것은 이 글을 이해하는데 상당히 도움이 되리라 믿는다. 다음으로, 주제의 논의를 통한 "理想的인 租稅制度"를 소개하였다. 결론적으로, 이 글에서는 "이상적인 세제"로의 전환은 한 국가의 정치 및 경제 엘리트들의 강한 의지와 국민들의 기대가 가장 잘 조화를 이루는 점에서 가능하다고 보았다. 다시 말해서, 사회에서 요구되는 세제개혁의 문제는 곧 그 사회의 리더쉽 문제이고, 국민 역시 그 문제에 깊은 관심을 보였을 때 가능하다는 것이다.

Kinetic Studies on Bromine-Exchange Reactions of Antimony Tribromide with $\alpha$-Phenyl-n-butyl and $\alpha$-Phenyl-i-butyl Bromides in Nitrobenzene$^\dag$

Rhyu, Sok-Hwan,Choi, Sang-Up Korean Chemical Society 1987 Bulletin of the Korean Chemical Society Vol.8 No.5

The rate of bromine-exchange reaction between antimony tribromide and ${\alpha}-phenyl-n-butyl$ bromide in nitrobenzene has been determined, using antimony tribromide labelled with Br-82. The results indicate that the exchange reaction follows the first-order kinetics with respect to the organic bromide, and either the second- or first-order kinetics with respect to antimony tribromide depending on its concentration. The third-order rate constant obtained was 7.50 ${\times}10^{-2}l^2mol^{-2}s^{-1}$ at 28$^{\circ}$C. Similar study on the bromine-exchange reaction between antimony tribromide and ${\alpha}$-phenyl-i-butyl bromide has also been carried out. The results of the study show the same kinetic orders as the ones observed with $\alpha$-phenyl-n-butyl bromide. The third-order rate constant observed was 2.40 ${\times} 10^{-2} l^2mol^{-2}s^{-1}$ at 28$^{\circ}$C. The activation energy, the enthalpy of activation and the entropy of activation for the two exchange reactions mentioned above have been determined. The reaction mechanisms for the exchange reactions are discussed.

Expression of Human Endogenous Retrovirus <i>env</i> Genes in the Blood of Breast Cancer Patients

Rhyu, Dong-Won,Kang, Yun-Jeong,Ock, Mee-Sun,Eo, Jung-Woo,Choi, Yung-Hyun,Kim, Wun-Jae,Leem, Sun-Hee,Yi, Joo-Mi,Kim, Heui-Soo,Cha, Hee-Jae MDPI 2014 INTERNATIONAL JOURNAL OF MOLECULAR SCIENCES Vol.15 No.6

<P>Human endogenous retroviruses (HERV) <I>env</I> proteins have been recently reported to be significantly up-regulated in certain cancers. Specifically, mRNA and protein levels of HERV-K (HML-2) are up-regulated in the blood plasma or serum of breast cancer patients. Here, we collected blood samples of 49 breast cancer patients and analyzed mRNA expressions of various HERVs <I>env</I> genes including HERV-R, HERV-H, HERV-K, and HERV-P by real-time PCR. The expression of <I>env</I> genes were significantly increased in the blood of primary breast cancer patients but were decreased in patients undergoing chemotherapy to a similar level with benign patients. When we compared the group currently undergoing chemotherapy and those patients undergoing chemotherapy simultaneously with radiotherapy, HERVs <I>env</I> genes were reduced more in the chemotherapy only group, suggesting that chemotherapy is more effective in reducing HERV <I>env</I> gene expression than is radiotherapy. Among chemotherapy groups, HERV <I>env</I> gene expression was the lowest in the taxotere- or taxol-treated group, suggesting that taxotere and taxol can reduce HERVs <I>env</I> expression. These data suggest the potential to use HERVs <I>env</I> genes as a diagnosis marker for primary breast cancer, and further studies are needed to identify the mechanism and physiological significance of the reduction of HERV <I>env</I> gene expression during chemotherapy.</P>

Application of Three-Dimensional Light Microscopy for Thick Specimen Studies

Rhyu, Yeon Seung,Lee, Se Jeong,Kim, Dong Heui,Uhm, Chang-Sub Korean Society of Microscopy 2016 Applied microscopy Vol.46 No.2

The thickness of specimen is an important factor in microscopic researches. Thicker specimen contains more information, but it is difficult to obtain well focused image with precise details due to optical limit of conventional microscope. Recently, a microscope unit that combines improved illumination system, which allows real time three-dimensional (3D) image and automatic z-stack merging software. In this research, we evaluated the usefulness of this unit in observing thick samples; Golgi stained nervous tissue and ground prepared bone, tooth, and non-transparent small sample; zebra fish teeth. Well focused image in thick samples was obtained by processing z-stack images with Panfocal software. A clear feature of neuronal dendrite branching pattern could be taken. 3D features were clearly observed by oblique illumination. Furthermore, 3D array and shape of zebra fish teeth was clearly distinguished. A novel combination of two channel oblique illumination and z-stack imaging process increased depth of field and optimized contrast, which has a potential to be further applied in the field of neuroscience, hard tissue biology, and analysis of small organic structures such as ear ossicles and zebra fish teeth.

Dynamic Analysis of Double Excited 3-DOF Motor Modeling Using Equivalent Magnetic Circuit

Rhyu, Se-Hyun,Shin, Hye-Ung,Kim, Min-Soo,Kwon, Byung-Il The Korean Institute of Electrical Engineers 2015 Journal of Electrical Engineering & Technology Vol.10 No.3

This paper implements a model of a double excited three-degree-of-freedom motor (3-DOF) coupled with a PI current controller for position control. The rotational trends of the rotor according to the applied steps are identified using a motion equation. The simulation model is a complete electrical and mechanical model of a 3-DOF motor, which mainly consists of mechanical torque equations, a nonlinear equivalent magnetic circuit, and a PI current controller. This machine is tested using the manufactured control board using the same conditions as in the simulation, where the experimental results also verify the accuracy of the simulation results.

The enterprising evaluation for the Korean National Long-Term Ecological Research (KNLTER) Project for six years (Review)

Rhyu, Tae-Cheol,Yang, Byung-Gug The Ecological Society of Korea 2011 Journal of Ecology and Environment Vol.34 No.1

The Korean National Long-Term Ecological Research (KNLTER) project seeks to predict the effects on Korean ecosystems caused by stress derived from environmental changes from a national perspective. The objective of this article about the KNLTER program, continuously supported by the Ministry of Environment (MOE) since 2004, was to inspect the general plans and to evaluate the project for the KNLTER program objectively, and to make suggestions about the developmental direction of the project. As a result of evaluation on the research site, the numbers of research sites in 2010 correspond to 50% of those presented in the basic plan of the KNLTER project. As a result of evaluation on the research contents in the terrestrial ecosystem section of the KNLTER project, monitoring of climatic and atmospheric changes using eco-towers should be conducted over a long-term period. Additionally, the soil respiration part of the study needs to be expanded further in order to better understand soil systems. In the freshwater ecosystem section, we need to establish common standard investigation items, which can be used as indicators of the actual freshwater environment, considering that freshwater ecosystem management is closely related to human life. In the coastal ecosystem section, we should intensively analyze the correlation between the collected data accumulated thus far, as well as environmental changes including climate change, pollution, etc. For very sensible cases such as topographic changes due to rises in sea level, we should generate data applicable to prediction and confrontation for future changes through the continuous addition of variables and applications of a variety of simulation methods. In the animal ecology section, we should evaluate ecosystem changes based on animal phenology by selecting indicator animal species, which can be applied to each relevant ecosystem: namely, terrestrial, freshwater, and coastal ecosystems. As a result of synthetic evaluation conducted under the auspices of KNLTER, the stability of study areas is frequently implicated as the most common problem. If private lands are designated as study sites, it is very difficult to maintain them as study sites for a prolonged period. Therefore, it is necessary to designate national and public lands, such as national or provincial parks, as study sites. Efforts thus far conducted toward the construction of an appropriate database and modeling studies remain insufficient. After investigating the phenology of the specific species growing in all research sites, it is necessary to assess and report the overall changes in Korean ecosystems by applying that knowledge. The collection, analysis, and systematization of recent domestic and foreign research data related to natural ecosystem changes owing to environmental changes such as climate change and environmental pollution have been insufficient. Therefore, studies performed to obtain this information should be continuously pursued in the third stage.

Communication Redundancy for Reliability Improvement in an Industrial Monitoring and Control System

Rhyu, Keel-Soo,Chung, Kyung-Yul The Korean Society of Marine Engineering 2004 한국마린엔지니어링학회지 Vol.28 No.8

In development of monitoring and control systems, one of the most important points is to consider a redundancy so that the system can be operated normally although hardware faults are partly occurred. The purpose of this paper is to introduce a monitoring and control system with a redundancy function for I/O servers and communication networks. I/O servers composed with an active server and a standby server. Each server also has 3 communication ports, 2 ports of them were connected to field units and the other 1 port was connected to the other server. Field units have to be constructed to 2 communication ports connected I/O servers through communication lines. Also, server communication module was implemented for analyzing and handling fault elements. and was submodularized for linking easily with a monitoring and control module. An experiment with 2 servers and 2 field units was constructed to demonstrate its effectiveness.
