Zirconium-doped $Li_{1.1}Co_{1-x}Zr_xO_2(0{\leq}x{\leq}0.05)$ powders as cathode materials for lithium ion batteries were synthesized using an ultrasonic spray pyrolysis method. Cyclic voltammetry and cyclic stability tests were performed, and the changes of microstructure were observed. The solubility limit of zirconium into $Li_{1.1}CoO_2$ was less than 5 mol%, and monoclinic $Li_2ZrO_3$ phase was formed above the limit. The Zr-doping suppressed the grain growth and increased the lattice parameters of the hexagonal $LiCoO_2$ phase. The Zr-dopiong of 1mol% resulted in the best cyclic performance in the range of $3.0{\sim}4.3V$ at 1C rate (140 mA/g); the initial discharge capacity decreased from 158 mAh/g to 60 mAh/g in the undoped powder, while from 154 mAh/g to 135 mAh/g in the Zr-doped powder of 1 mol% after 30 cycles. The excellent cycle stability of Zr-doped powder was due to the low polarization during chargedischarge processes which resulted from the delayed collapse of the crystal structure of the active materials with Zr-doping.

알루미늄이 첨가된 Li(Ni_1/3Co_1/3Mn_1/3-xAl_x)O₂ 양극활물질의 전기화학적 특성

김선혜,심광보,김창삼,Kim Seon-Hye,Shim Kwang-Bo,Kim Chang-Sam 한국전기화학회 2006 한국전기화학회지 Vol.9 No.2

초음파분무열분해법과 한 단계의 후열처리로 이차상이 없는 Al이 첨가된 $Li(Ni_{1/3}Co_{1/3}Mn_{1/3-x}Al_x)O_2$ (x=0.0, 0.005, 0.01. 0.05) 리튬이차전지용 양극활물질을 합성하였다. 합성된 분말은 Al의 첨가량이 많아짐에 따라서 $I_{003}/I_{104}$ 비는 감소하고 입자가 커지는 경향을 보였다. 상온에서 전류밀도 1C의 rate로 $3.0\sim4.5V$ 범위에서 충방전 시험한 결과, Al 치환량이 0.5와 1.0 at%에서는 초기용량이 180과 $184mAhg^{-1}$으로 치환하지 않았을 때의 $182mAhg^{-1}$과 차이가 없었으며, 싸이클 특성도 치환하지 않은 것과 0.5, 1.0 at% 치환한 조성에서 각각 81, 77, 81%의 방전용량이 유지되었다. 그러나 $3.0\sim4.6V$에서는 치환효과가 확실하게 나타나서, 50 싸이클 후의 치환하지 않은 것의 방전용량은 초기용량의 30%가지 감소한데 비하여 Al을 0.5 at% 치환한 것은 70%를 유지하였다. 치환에 의한 싸이클 특성 향상은 XPS 분석 결과 Al 치환이 $Mn^{3+}$의 양을 감소시켰기 때문인 것으로 사료되었다. Cathode materials of Al-doped $Li(Ni_{1/3}Co_{1/3}Mn_{1/3-x}Al_x)O_2$ (x=0.0, 0.005, 0.01 0.05) for lithium ion batteries were synthesized with ultra-sonic spray pyrolysis method and single-step heat treatment. No secondary phases were found in all synthesized powders. The intensity ratio of $I_{003}\;to\;I_{104}$, however, slightly decreased and the particle size increased with the Al contents. The cells with bare, 0.5 and 1.0 at% Al-doped powders showed the initial discharge capacities of 182, 180 and $184mAhg^{-1}$ in a voltage range of $3.0\sim4.5V$ at 1C rate, and the capacity retentions of 81, 77 and 78% at the end of 30 cycles, respectively. But in the voltage range of $3.0\sim4.6V$, the Al-doping significantly enhanced the cycle stability. For example, the discharge capacity after 50 cycles was maintained to 70% in the 0.5 at% Al-doped sample compared to only 30% in no doped sample. The improvement of the cycle stability was thought to be due to $Mn^{3+}$ ion decrease as the Al doping from the XPS analysis results.

김선혜(Seon-Hye KIM),김수영(Soo-Young KIM) 한국상담심리교육복지학회 2020 상담심리교육복지 Vol.7 No.1

본 연구는 유아의 부정 정서조절에 영향을 미치는 유아의 내적(기질, 놀이성, 일상적 스트레스)변인과 외적(어머니의 기질, 정서조절, 양육스트레스)변인들을 동시에 고려하여 분석해 보고 유아의 부정 정서조절과의 관계를 살펴보는데 목적이 있다. 본 연구대상은 K도 K시에 소재한 K유치원에 다니는 만 3,4,5세 유아 어머니 140명을 대상으로 설문지를 배포하였으며 132부가 회수되었다. 이들 중 응답이 불성실한 설문지를 제외한 113명이 최종 연구대상으로 선정되었다. 연구결과 첫째, 유아기질 하위영역 중 활동성, 적응성이 부정 정서조절과 유의한 정적상관이 있었다. 유아 놀이성이 부정 정서조절과 유의한 부적상관이 있었다. 유아의 일상적 스트레스 하위영역 중 자존감 상함, 비난·공격적 상황에 접함, 그리고 유아의 일상적 스트레스 전체가 부정 정서조절과 유의한 부적상관이 있었다. 둘째, 어머니의 기질, 어머니의 정서조절방식, 어머니의 양육스트레스는 유아의 부정 정서조절과 유의한 상관이 없었다. The purpose of this study is to investigate the relationships with the young children s regulation of negative emotions after considering and analyzing the young children s internal variables (temperament, playfulness, daily stress) and external variables (mother s temperament, emotion regulation, parenting stress) which affect the young children s regulation of negative emotions simultaneously. For research object, this study was to distribute the questionnaire as an object of 140 mothers for three, four and five-years-old in full children who attended in K kindergarten located in K City of K Province, and 132 copies were retrieved. Among them, 113 respondents excluding the unreliable respondents from the questionnaire were selected as final research object. From the result of this research above, it may be summed up as follows. First, among the subfields of children s temperament, the activity and adaptability had significant positive correlation with the negative emotion regulation. The children s playfulness had significant negative correlation with the negative emotion regulation. Among the children s daily stress subfields, a loss of self-esteem, facing with the blame and attack situation, and the children s whole daily stress had significant negative correlation with the negative emotion regulation. Second, the mother s temperament, method of mother s emotion regulation, and mother s parenting stress had no significant correlation with the young children s regulation of negative emotions.

명대 휘주의 종족제 발달과 소송

爲了理解明代徽州的`健訟`問題, 首先不可不指出徽州人們特有氣質, 風俗的影響. 不過, 爲了把握更正確的背景. 須要總體考慮自然環境和社會組織及經濟活動之間的關連. 在徽州營爲社會經濟生活的最重要結構, 就是宗族. 所以我想考察, 徽州宗族制發達與訴訟. 有什마關係. 嘉靖年間以後, 一般認爲祠堂祭祀的限制取消了, 所以祖上祭祀遡及到始遷祖或始祖. 宗族常常維持`聚族而居`或`累世同居`的居住形態. 以決定宗族結合範圍下來. 但是, 祭祀範圍擴大到始遷祖或始祖. 以通過祭祀儀禮, 整個男系親共有血綠衣意識, 所以能擴大宗族結合範圍. 還有徽州商人的積極後援之下, 宗族組織更爲强化. 明中期以後. 徽州宗族比以前擴大了結合範圍. 其强度也成爲堅固, 以所有日常生活不得不關係與宗族, 因此在宗族內部. 也産生葛藤, 發展到訴訟了. 與他種族的個別分爭是, 以全宗族次元的問題擴大了, 更出現了複雜樣相. 宗族之間的訴訟是, 收集整個有關文件, 以編輯單獨案卷或收錄族譜內的事例比較多. 我們把握事件全貌的時候, 這些訴訟案卷, 比散件文書更有好處. 分析了幾件宗族之間訴訟事例的結果. 我能確認宗族之間的訴訟有紛爭對象, 期間, 被反復的上告等類似特徵. 宗族之間的訴訟, 像體寧縣的著存觀, 翕縣的眞應廟·楊于寺. 與宗族組織有關的問題比較多. 宗族結合强化起來. 宗族想通過訴訟. 還收他們的權利起來了. 還有到了明後期. 隨着宗族組織的整備·擴大, 佃僕制的需要越來越多. 但是想脫開身分束縛的佃僕和想一直保留`主僕之分`的主家之間. 葛藤越來越嚴重, 所以宗族之間圍繞佃僕的鬪爭和訴訟也增加. 更爲複雜地展開. 與宗族組織有關的紛爭發生事例比較多. 所以大體上可能說訴訟期間比較長. 萬曆年間, 祁門縣`謝氏訴訟`那樣, 宗族內部的訴訟. 才幾個月以後, 知縣能解決了. 不過我能確認, 宗族之間的訴訟, 短的話一年, 長的話九十餘年以後才解決了. 兩個宗族的利害關係對立, 誰也不退步, 毋論知府, 巡按御史. 互相上告到上級衙門, 甚至皇帝下令以後才解決的事例也有. 因此不得不費了흔長期間. 就是說宗族間訴訟是, 長撻時間. 一層複雜展開了. 以上看來, 我認爲徽州人的訴訟頻繁背景是, 與明中期以後 宗族制發達有深刻的關連. 所以可能說, 特因明中期以後社會經濟的變化, 擴大旣存矛盾, 或者産生新紛爭因素, 以徽州訴訟問題變成漸漸深化.

미용실 창업 교육 경험이 점포 환경 구축에 미치는 영향

조각에서 촉각의 의미와 교육적 함의

김선혜(Kim, Seon-Hye) 한국미술교육학회 2010 美術敎育論叢 Vol.24 No.3

오늘날 시각문화에서 촉각은 제품의 생산에 중요한 요소로 작용하며 미술작품제작 측면에서는 작품의 형식과 내용을 결정하는 요소라는 점에서 본질적인 중요성을 가진다. 그러나 편향된 감각중심의 사회와 미술교육의 위축으로 인해 촉각교육을 통한 전인적 인간 육성에 어려움이 있다. 이에 본 연구는 촉각의 함축적인 의미를 살펴본 후 촉각과 밀접한 관계성을 가진 조각과의 연관성을 살펴보았다. 촉각은 인간의 감각 중 인체와 가장 광범위하게 연결되어 있으며 다른 감각을 통합시켜 줄 수 있는 촉매로서 역할을 한다. 특히 조각을 촉각예술이라고 할 만큼 촉각은 미술의 영역 중 조각과 밀접한 연관을 가진다. 조각은 촉각을 기준으로 단단한 조각과 부드러운 조각으로 분류 할 수 있는데 부드러운 조각은 관습적인 조각의 개념을 더욱 확장시키며 이는 현대사회의 특성을 반영한 것이다. 촉각을 포함한 감각 교육은 손을 통한 교육으로 실현될 수 있으며 이를 통해 아동의 균형 있는 성장과 창의적 사고를 기르는데 교육적 함의가 있다. 이는 지식중심 사회에서 미술교육의 정당성을 뒷받침해준다. The tactile sense serves as an important element of production in visual culture and it is an essential element in terms of format and content of the work. However, there are many difficulties in holistic human development through tactile sense education due to a reduction in art education and cultural bias. So at first this research will seek the implicit meaning of the tactile sense and it will search the relationship between the tactile sense and sculpture that is closely related to the tactail sense. Of all human senses, the tactile sense is the most widely connected with the human body and it can act as a catalyst that integrates with other senses. In addition, the tactile sense is more closely associated with sculpture than other areas of art. Based on the tactile sense, sculpture can be divided into a solid type and a soft type. The soft type sculpture expands the typical concept of sculpture so it leads us to new experiences; it also reflects the characteristics of our society. There are educational implications in terms of a sensory education that includes the tactile sense. Children's creative thinking and intuition can be enhanced through the use of hands-on activities. This idea supports the justification of art education in our knowledgebased society.

As diverse information increase, consumer requirements need to be satisfied, and studies on positive improvement measures and prevention methods for customer dissatisfaction and complaint behaviors are required to attract and maintain customers. This study aims to empirically analyze the effect of dissatisfaction with each level of service at beauty parlors and customer participation behavior on dissatisfaction and complaint behaviors after purchase of service, and suggest effective countermeasures and improvements. Research findings are as follows. First, the level of dissatisfaction with each level of service at beauty parlors and customer participation behavior, and behaviors after purchasing beauty services were examined. As for the dissatisfaction with each level of service, four factors of customer response dissatisfaction, beauty procedure process dissatisfaction, dissatisfaction when paying/leaving the shop, and consultation dissatisfaction were deducted. As for the customer participation behavior, two factors of passive and active participation were deducted. As for the behavior after purchasing beauty services, three factors of active complaint behavior, dissatisfied feelings, and passive complaint behavior were deducted. Third, the effects of dissatisfaction with each level of service at beauty parlors and customer participation behavior on the behavior after purchasing beauty services were examined, and it was revealed that the factors of customer response dissatisfaction, beauty procedure process dissatisfaction, consultation dissatisfaction, active participation and passive participation had positive effects on active complaint behaviors, dissatisfied feelings, and passive complaint behaviors. To conclude, it is necessary to implement a methodical service management system that can grasp and prevent service dissatisfaction and complaint behaviors at beauty parlors.
