양극산화법에 의한 TiO<sub>2</sub> 나노튜브 어레이의 제조와 성장거동

Recently, $TiO_2$ nanotubes have considerably researched because of their novel application about photocatalysis, dye-sensitized solar cells (DSSCs), lithium ion battery, etc. In this work, self-standing $TiO_2$ nanotube arrays were fabricated by anodic oxidation method using pure Ti foil as a working electrode in ethylene glycole with 0.3M $NH_4F$ + $2%H_2O$. Growth behavior of $TiO_2$ nanotube arrays was compared according to temperature, voltage and time. The morphology, structure and crystalline of anodized $TiO_2$ nanotube arrays were observed by FE-SEM (field emission scanning electron microscope) and XRD (X-ray diffraction).

Recently artificial intelligence technology has been introduced in various fields and various machine learning models have been operated in various frameworks as academic interest has increased. However, these frameworks have different data formats, which lack interoperability, and to overcome this, the open neural network exchange format, ONNX, has been proposed. In this paper we describe how to transform multiple machine learning models to ONNX, and propose algorithms and inference systems that can determine machine learning techniques in an integrated ONNX format. Furthermore we compare the inference results of the models before and after the ONNX transformation, showing that there is no loss or performance degradation of the learning results between the ONNX transformation.

양극산화법에 의한 TiO<sub>2</sub> 나노튜브 어레이의 제조 및 광전기화학적 특성에 관한 연구
김선민,조권구,최영진,김기원,류광선,Kim, Seon-Min,Cho, Kwon-Koo,Choe, Yeong-Jin,Kim, Ki-Won,Ryu, Kwang-Sun 한국분말야금학회 2010 한국분말재료학회지 (KPMI) Vol.17 No.3
Self-standing $TiO_2$ nanotube arrays were fabricated by potentiostatic anodic oxidation method using pure Ti foil as a working electrode and ethylene glycol solution as electrolytes with small addition of $NH_4F$ and $H_2O$. The influences of anodization temperature and time on the morphology and formation of $TiO_2$ nanotube arrays were investigated. The fabricated $TiO_2$ nanotube arrays were applied as a photoelectrode to dye-sensitized solar cells. Regardless of anodizing temperature and time, the average diameter and wall thickness of $TiO_2$ nanotube show a similar value, whereas the thickness show a different trend with reaction temperature. The thickness of $TiO_2$ nanotube arrays anodized at $20^{\circ}C$ and $30^{\circ}C$ was time-dependent, but on the other hand its at $10^{\circ}C$ are independent of anodization time. The conversion efficiency is low, which is due to a morphology breaking of the $TiO_2$ nanotube arrays in manufacturing process of photoelectrode.

옹정(雍正)-건륭년간(乾隆年間) 망우초(莽牛哨) 사건(事件)과 청(淸)-조선(朝鮮) 국경지대(國境地帶)

Even after the establishment of the tributary relationship between the Qing and Choson courts, local people continued to violate borders in search for ginseng, and border transgression incidents, in fact, did not disappear until the end of the nineteenth century. It is interesting to find that as time passed, responses from the Qing court to Korean trespassers gradually changed: if the early Qing rulers who strove to secure their fragile country in the hostile environment attempted to impose a rather harsher policy to curb their reluctant neighbor, their descendents in the eighteenth century when the Qing empire reached its apex became more lenient to their submissive tributary state. Punishments for Korean trespassers were reduced, while curbing on the Qing side was strengthened through issuing the imperial edicts. In the mid-eighteenth century when Qing local officials in the northeastern frontier proposed to station soldiers at a border post near Choson as a way to prevent Korean trespassing, the Choson made an all-out effort to stop the Qing from approaching near the border and their territory. Finally the Qing emperor decided to accept the Choson appeal and not to place soldiers at the border, a dramatic contrast with the cruel attitude of the early Qing rulers to the Korean border trespassers. Just as much the Qing emperor wished to reinforce the justice of their claim to the Mandate of Heaven within the empire, they wanted to posture themselves as a benevolent ruler to even embrace foreign subjects. For eighteenth-century Qing rulers, border security with an unintimidating neighbor was an issue of less significance than gaining respects from an old tributary state.

최근 새로운 비즈니스모델을 창출 할 목적으로 창조경영을 도입, 추진하는 기업들이 많아지면서 다양한 성공사례들이 언급되고 있다. 그러나 이러한 노력들이 너무나 다양하며 단편적인 일화들로만 부분적으로 알려져 있어 실태가 명확하게 알려져 있지 않다. 본 연구의 목적은 이러한 사정을 이해하고 국내 기업들이 경영활동과 의사결정에서 창조성을 어떻게 보고 다루고 있는가를 체계적으로 검토하는 것이다. 본 논문에서는 평가 체계로 기업경영의 혁신 시스템 중의 하나인 말콤볼드리지 기준의 경영시스템 개념을 준거 틀로 활용하여, 창조경영에 대한 기존의 문헌자료 분석을 기초로 구성된 조사프레임워크를 사용하였다. 총 95개의 유효 설문을 분석하여 국내 기업들의 창조성 경영에 대한 실태를 파악하였다. Recent Korean companies show lots of interests to new business creation. However, as these efforts are too diversified and only anecdotes are separately known, we knowvery little on its reality. This paper aims to reviewand investigate somewhat systematically how firms address these issues through their decisionmaking and business activities. The well-knownMalcolmBaldridge Award for Total Quality Management assesses companies according to their management subsystems of 7 major categories, the frame of which is usually used for understanding business innovation. This paper accept the same idea. Based on the MB framework and reviewed literatures we develop a survey for howcompaniesmanage for their business creativity.

전근대 동아시아 국제관계의 재인식 ; 외국과 속국의 사이 -正史를 통해 본 청의 조선 인식-

By focusing on Qing narratives of the Choson in Official Histories (正 史, zhengshi), especially the Mingshi (明史, History of the Ming) and the Qingshigao (淸史稿, Draft History of the Qing), this paper aims to address specific meanings and contexts of Qing-Choson relationship, and explain the ways in which Qing`s internal transformation caused changes in its foreign relations. Both the Mingshi and the Qingshigao have a section of Chaoxianzhuan (朝鮮傳, Biographies of the Choson), but they classified this same neighbor in different names. While the Mingshi named the Choson waiguo (外國, foreign country), the Qingshigao called it shuguo (屬國, subordinate state). This paper argues that the two Biographies of the Choson included in the Mingshi and the Qingshigao depicted ideal images of the Choson - a loyal neighbor serving for China - as the way that the Qing emperors in the eighteenth century and the former Qing officials in the early twentieth century expected. They were not necessarily intended to introduce correct and detailed information on the Choson, but instead demonstrated Qing perspectives of the Choson as well as itself in the eighteenth century and the twentieth century, respectively. As much as the eighteenth-century Qing was different from the twentieth-century China, the description of the Choson - and Qing`s self-description - in the Mingshi was different from those in the Qingshigao. By exploring the differences in these two Official Histories, this paper seeks to highlight that the Qing and the Choson were not an eternal, unchanging entity, but instead, they had established an ever-changing relationship throughout the long history of their contacts.
