Suppressing Lateral Conduction Loss of Thin-film Cathode by Inserting a Denser Bridging Layer

박종훈,이성환,김형철,윤경중,이종호,한승민,손지원 한국세라믹학회 2015 한국세라믹학회지 Vol.52 No.5

To reduce the lateral conduction loss of thin-film-processed cathodes, the microstructure of the thin-film cathode is engineered to contain a denser bridging layer in the middle. By doing so, the characteristic crack-like pores that separate the cathode domains in thin-film-processed cathodes and hamper lateral conduction are better connected and, as a result, the sheet resistance of the cathode is effectively reduced by a factor of 5. This induces suppression of the lateral conduction loss and expansion of the effective current collecting area; the cell performance is improved by more than 30%.

后山 鄭胤永의 연작 八老詩 일고찰

박종훈 온지학회 2020 溫知論叢 Vol.0 No.65

The Song Dynasty's Liu kezhuang has written 10 works on the theme of old age. The work is called ten poems about old age. Under these influences, works on the theme of age were continuously built in Joseon. The rough content is lamentation about old age and skill due to old age. In terms of formality, it followed the basic form of the Liu kezhuang. However, the format and the object were altered by each writer. This was an effort to overcome the negative view of Liu kezhuang. First of all, I have grasped the flow of Joseon. Of course, I think there will be much more works than this. In order to gain access to the rough content, this paper first focused on Jung Yun-young's ‘Eight poems about old age’. Jeong Yun-yeong has composed eight works each for people and trees. In the work aimed at people, the main content is lamentation about old age and praise for old age. Also, through the constant contrast of age and skill, the focus was on skill. In the end, he overcame his old age with his skills and captured the leisurely life of his old age. Eight works on trees are also focused on robustness rather than old age. Praise was given to each subject by actively utilizing various examinations related to each subject. He also expressed his willingness not only to praise the object but to actively accept it in his life. He aimed to bring things together and to design his own life in old age. This paper has considerable limitations in the starting point of full-fledged discussion on Ten poems about old age. I will overcome these limitations one by one through continuous interest. 宋나라 劉克莊은 노년을 주제로 10수의 연작시를 지은 바 있다. 이를 보통 ‘十老詩’라고 한다. 이러한 영향 하에 조선에서도 지속적으로 노년을 주제로 한 연작의 작품이 지어졌다. 그 대략적인 내용은 노년에 대한 탄식과 세월의 흔적으로 인한 노련함과 노건함이다. 형식적인 측면에서는 유극장의 칠언율시라는 기본적인 형식을 그대로 이어받으면서, 형식이나 대상에 대해서는 각 작가의 나름대로의 변주가 일어났다. 결국 내용이나 형식의 변주는 유극장의 작품에 대한 부정적인 시각을 극복하려는 노력의 일환인 셈이다. 노년을 주제로 한 작품군에 접근하기 위해서 우선 조선에서의 흐름을 대략 살펴보았다. 물론 이 보다 훨씬 많은 작품이 있을 것이다. 또한 그 대략적인 내용에 접근하기 위해, 본고에서는 우선 鄭胤永의 八老詩에 초점을 맞추었다. 그는 인물과 나무만을 대상으로 각각 8수의 연작시를 지은 바 있다. 모두 차운한 작품이기에 原韻의 작품도 있을 것이다. 인물을 대상으로 한 작품에서는 노쇠함에 대한 탄식과 노련함에 대한 칭송이 주를 이루었다. 또한 노쇠함과 노련함의 지속적인 대비를 통해, 노련함에 무게감을 두기도 했다. 결국 노련함으로 노쇠함을 이겨냈고 自樂하는 여유로운 노년의 삶이 담겨졌다. 나무만을 대상으로 한 8수의 연작시 역시 늙음보다는 老健함에 초점이 맞춰졌다. 각 대상과 관련된 다양한 고사를 적극 활용하여, 대상에 대한 칭송이 이루어졌다. 대상에 대한 칭송에만 머물지 않고 이를 자신의 삶에 적극 수용하려는 의지도 드러냈다. 물아일체를 지향한 것으로, 이를 통해 노년의 자신의 삶을 설계한 셈이다. 본고는 십로시에 대한 본격적인 논의의 출발점에 있어, 적지 않은 한계를 안고 있다. 지속적인 관심을 통해 이러한 한계를 하나씩 극복해 나가고자 한다.

지식 중심의 국어교육 내용 범주 설정 시론

박종훈 한국어교육학회 2005 국어교육 Vol.0 No.117

The purpose of this study is to suggest contents categories of Korean language education as mother tongue. Discriminating contents from objectives, we found only knowledge as contents category. It is not only contents but also objective. Skill is a kind of status so it is not contents but objective. Strategy is divided into two sort, C-strategy and K-strategy. C-strategy cannot be taught due to its creativity and situation-dependency and K-strategy is just a kind of procedural knowledge. Activity is very important but it is not content but method. Attitude is also a kind of status so it is not contents but objective. In sum, contents category of Korean oral communication education is only knowledge whereas knowledge, skill and attitude is objective categories. To arrive at this objectives with contents(knowledge), various activities must be introduced. Analyzing the constituent and procedure of Korean language use, we found that knowledge can be divided into sub-categories. It is divided into functional and procedural knowledge. Functional knowledge is about the relation between context and wording whereas procedural one is about the performance method. these sub-categories are valid in two level of language use; language performance and meta-language performance.

王世貞의 ‘文章九命’과 朝鮮 文人의 수용 양상

박종훈 한서대학교 동양고전연구소 2016 東方學 Vol.35 No.-

明나라 문인 王世貞의 문학론은 당대 중국뿐만 아니라, 조선에도 적지 않은 영향을 끼쳤다. 특히 復古와 관련된 文必秦漢 詩必盛唐 등의 논의는 이후 조선 문인들도 적극 수용하면서 논의를 전개했다. 이에 본고에서는 왕세정의 『藝苑卮言』 권8에 실린 ‘文章九命’을 조선 문인들이 어떻게 수용하고 있는 지 살펴보았다. 이는 조선 문인에게 끼친 왕세정의 영향을 살피기 위한 일단임을 우선 밝힌다. 먼저『藝苑卮言』의 ‘문장구명’을 간략히 살펴보았다. 왕세정이 ‘문장구명’을 저술한 이유는, 문학적 재능을 가지고 있었지만, 현실과의 불협화음으로 인해 곤궁하게 살았거나 어려움을 겪은 역사적 인물에 대한 애도가 주된 것이었다. 물론 고난 속에서도 훌륭한 문학 작품을 양산한 것에 대한 칭송의 의미도 담겨 있다. 貧困, 嫌忌, 玷缺, 偃蹇, 流竄, 刑辱, 夭折, 無終, 無後 등 총 9개 항목으로 나누어, 이에 해당하는 역사적 인물을 소개했다. 동일 인물이 다른 항목에 걸쳐 있는 경우도 적지 않았으며, 唐代 인물이 많다는 점도 특징 중 하나라 하겠다. 이어 ‘문장구명’과 관련된 조선 문인들의 수용 양상을 살펴보았다. 조선 문인들은 說, 序, 書, 祭文, 挽詞, 墓誌銘, 古詩, 送別詩 등 다양한 글에서 왕세정의 문장구명을 인용하면서, 자신들의 논의를 배가시켰다. 물론 이들 작품의 주된 내용은 왕세정처럼, 文才를 갖춘 이들의 불우한 삶에 대한 애도와 그들이 남긴 작품에 대한 칭송이다. Wang Shi Zhen`s the theory of literature had an effect not only China but also Jeseon. Especially, This argument in connection with restoration that 〈The words must return to Ch`in Han, The poetry must return to Sheng T`ang〉, be developed that Jeseon writers positively accept. So, I looked around Jeseon writers how accepted ‘Munjanggumyeong(文章九命)’ that be carried 『Yewonchiyan(藝苑卮言)』 Vol. 8 of Wang Shi Zhen. First of all, I praised that Wang Shi Zhen did harm to Joseon writers. The First, I considered ‘Munjanggumyeong’ of 『Yewonchiyan』. Wang Shi Zhen wrote ‘Munjanggumyeong’. Because He had literary ability. But, He made a compromise with a reality. So, he was very important that condolence about historical person that experienced distress or lived in poverty. Of course, He made good literary works in the difficulty. and it was appeared his praise. He classified all 9 items that a poverty(貧困), an aversion(嫌忌), a fault(玷缺), an haughtiness(偃蹇), a banishment(流竄), A cruelly injure(刑辱), a premature death(夭折), Endlessness(無終), A having no posterity(無後) and so on. and he introduced historical personages. At this book, It was numerous an instance that one person came onstage other items. and It was a peculiarity that was much Tang`s people(唐代) considered Joseon writers` reception aspects be related to ‘Munjanggumyeong. Joeson writers quoted diverse sentence that a theory(說), a preface(序), a letter(書), a funeral oration(祭文), a funeral ode(挽詞), an epitaph(墓誌銘), an ancient poetry(古詩), a farewell poem(送別詩) and so on, at ‘Munjanggumyeong’ of Wang Shi Zhen. so they were doubled their argument. Undoubtedly, their works were appeared that the deepest regret about their dark days with literary talent and an admiration about they leaved works as Wang Shi Zhen. Wang Shi Zhen`s Munjanggumyeong had was a influence at 『KyungjungMunjanggumyeong(更定文章九命)』 of Wang Tak on the Qing Writer. Wang Shi Zhen introduced writers of many generations with total 9 items in directly opposed stand-point. Wang Shi Zhen was centering around the memory, in that case Wang tak was the intention that admonished writers. It was entered works that 『KyungjungMunjanggumyeong』 of Wang Tak. Also, It was that Joseon writers would often appeared. I thought very interesting thing that compared two people`s works, who Wang Shi Zhen and Wang Tak. and I thought next homework that Joseon writers how receptived.

Analysis of periodic test policy for a standby unit under three types of failures

박종훈 한국산업경영시스템학회 2012 한국산업경영시스템학회 학술대회 Vol.2012 No.춘계

This paper derives the limiting availability of the standby unit by considering three types of failures. Assuming the standby unit can fail during the standby period (type Ⅰ failure), the periodic test is employed to check the unit condition. Although the periodic test is capable of detecting failures during the standby period, it can cause test-induced failures for the standby unit at the start of the test (type Ⅱ failure). Also the aging process of the standby unit during the test period needs to be taken into account (type Ⅲ failure), which is not treated in the existing studies. To identify relationships between the optimal periodic test interval an various failure characteristics of the standby unit. several experiment are performed assuming Weibull distribution as an operating time distribution of the standby unit. The result of this paper can be applied to determine an appropriate test interval for the standby unit in priority redundant system to enure higher reliability characteristics.

박종훈,한경수,김문규,Park, Jong-Hoon,Han, Kyung-Soo,Kim, Moon-Gyu 대한안면통증구강내과학회 2000 Journal of Oral Medicine and Pain Vol.25 No.1

This study was performed to investigate the effect of three modalities commonly used for reduction of oral malodor and to review the contributing factors for halitosis. For this study, 45 subjects of good general health in their third decades were selected, and they were divided into three groups by each modality, that is, tongue scraping, $ZnCl_2$ mouth rinse, and periodontal treatment. Subjective sense of halitosis, diets, Oral hygiene index based on tooth brushing and tongue brushing habit, resting salivary flow rate, gingival index, degree of tongue coating were recored in the Halito-Chart designed by the author. Oral malodor converted from volatile sulfur compound was measured by the Halimeter$^{(R)}$(Interscan Co., USA), and the correlation between the oral factors and pre-treatment halimeter score were analysed. Data obtained were analysed by the SPSS windows program and the results of this study were as follows : 1. There were no significant correlation between oral factors such as oral hygiene index, salivary flow rate, gingival index, degree of tongue coating and pre-treatment halimeter score. 2. Difference between pre- and post-treatment halimeter score by the three modalities were significant, but correlation between pre- and post-treatment score within group was most significant in the periodontal treatment group followed by the tongue scraping group and lowest in the $ZnCl_2$ mouth rinse group. 3. Reduction of halimeter score was significant only in subjects with relatively more tongue coating in the tongue scraping group, but in the $ZnCl_2$ mouth rinse group and in the periodontal treatment group, the modality applied to each group had same significant effects without regard to the degree of oral hygiene index or gingival index. 4. Men had more tongue coating than women, and reduction of halimeter score was significant in men, but not in women.

근위 경골에 발생한 악성종양 절제 후 슬관절 신전력 재건술 -증례 보고-

박종훈,오정문,김진욱,이수용,Park, Jong-Hoon,Oh, Jung-Moon,Kim, Jin-Wook,Lee, Soo-Yong 대한근골격종양학회 2004 대한골관절종양학회지 Vol.10 No.2

근위 경골부에 발생한 악성종양의 사지구제술은 화학요법의 발달로 인해 대표적인 치료 방법이 되었다. 다양한 술식의 보고에도 불구하고, 종양 절제 후 종양 대치물을 이용한 사지구제술에 있어 슬개건의 부착 부위가 상실되어 슬관절의 신전력을 재건 하기가 어려운 것이 공통적인 문제로 지적 되고있다. 본 연구는 경골 근위부의 종양을 절제한 후 저온열처리 한 다음 원위 대퇴골을 절제하여 저온열처리 자가경골 및 종양대치물과 결합하고, 슬개골을 자가경골과 결합된 원위 대퇴골에 고정하여 슬관절 신전력을 재건 한 2례를 보고하고자 한다. Benign and malignant bone tumors occur most commonly around the knee. The proximal tibia is the most technically demanding site for limb salvage surgery. The most difficult problem using an endoprothesis for proximal tibial resection has been reconstruction of the extensor mechanism. After excision of proximal tibia, we resected distal femur and made a composite with resected distal femur, low heat treated autogenous proximal tibia and endoprothesis. Patella was fixed into the resected down-loaded distal femur. This article shows the new technique and the results of reconstruction of extensor mechanism after prosthetic replacement of the proximal tibia.
