탄소가 코팅된 일산화규소(C-coated SiO) 전극에서 전해질 첨가제로서 lithium bis(oxalato)borate(LiBOB)의 영향을 조사하였다. 전해질 조성은 1.3M $LiPF_6$/ethylene carbonate (EC), fluoroethylene carbonate (FEC), diethyl carbonate (DEC) (5:25:70 v/v/v)이며, 여기에 LiBOB을 0.5 wt.% 첨가한 것과 첨가하지 않은 2가지 전해질을 사용하였다. LiBOB을 첨가하지 않은 전해질에서 C-coated SiO 전극은 초기에 저항이 작은 피막이 형성되어 결정질의 $Li_{15}Si_4$를 형성할 때까지 합금화가 진행되며 동시에 큰 부피 변화를 보였다. 따라서 입자의 균열이 발생하고, 전극의 저항이 증가하여 충방전이 진행됨에 따라 용량이 빠르게 감소하였다. 반면에 LiBOB이 첨가된 전해질에서는 초기에 LiBOB의 환원분해에 의해 저항이 큰 피막이 형성되어, 합금화 반응이 원활히 진행되지 못하였다. 따라서 결정질 $Li_{15}Si_4$도 생성되지 못하였고, 결과적으로 부피변화도 적게 발생하므로 입자의 균열과 전극 저항의 증가도 적게 나타났다. 이러한 효과로 싸이클 후반부에서 용량감소가 적었고, 싸이클 성능도 좋은 결과를 보였다. 반면 피막 저항에 의한 영향이 줄어드는 $45^{\circ}C$ 에서는 LiBOB 첨가에 관계없이 합금화 반응이 유사하게 진행되며 비슷한 싸이클 성능을 나타내었다. As an electrolyte additive, the effects of lithium bis(oxalate)borate (LiBOB) on the electrochemical properties of a carbon-coated silicon monoxide (C-coated SiO) negative electrode are investigated. The used electrolyte is 1.3M $LiPF_6$ that is dissolved in ethylene carbonate (EC), fluoroethylene carbonate (FEC), and diethyl carbonate (DEC) (5:25:70 v/v/v) with or without 0.5 wt. % LiBOB. In the LiBOB-free electrolyte, the film resistance is not so high in the initial period of cycling that lithiation is facilitated to generate the crystalline $Li_{15}Si_4$ phase. Due to repeated volume change that is caused by such a deep charge/discharge, cracks form in the active material to cause a resistance increase, which eventually leads to capacity fading. When LiBOB is added into the electrolyte, however, more resistive surface film is generated by decomposition of LiBOB in the initial period. The crystalline $Li_{15}Si_4$ phase does not form, such that the volume change and crack formation are greatly mitigated. Consequently, the C-coated SiO electrode exhibits a better cycle performance in the later cycles. At an elevated temperature ($45^{\circ}C$), wherein the effect of film resistance is less critical, the alloy ($Li_{15}Si_4$ phase) formation is comparable for the LiBOB-free and added cell to give a similar cycle performance.

논문 : 월남 학병세대의 해방 후 8년 -학병세대 연구를 위한 시론(試論)

김건우 ( Kun Woo Kim ) 민족문학사학회·민족문학사연구소 2015 민족문학사연구 Vol.57 No.-

일제 말 제국의 고등교육을 받은 학병세대는 한국 현대지성사에서 가지는 중요성에도 불구하고 이제까지 연구가 거의 이루어지지 않았다. 해방 직후 이들은 이미 주목을 받고있었으며, 이후 한국사회 각 분야에 진출하여 국가를 설계하고 체계를 완성해 냈다. 1917-1923년에 태어나 해방 후 8년의 기간을 통해 ``남``을 선택한 월남 학병세대의 생각과 실천들을, 장준하 김준엽 선우휘 강원용 등 대표적인 월남 학병세대의 인물들을 통해 살펴봄으로써 향후 학병세대 연구의 기초를 만들고자 한다. While the student-soldier generation who were highly educated in the late japanese imperial period has considerable significance in the korean modern intellectual history, they have hardly been studied yet. In fact, they already held the public eye right after the liberation, and thereafter entered into various fields of korean society and designed the foundation of the state, completing the system of korea. This thesis tries to pave the way for the future studies on the student-soldier generation by examining the thoughts and practices of the ``Wollammin(persons displaced from North Korea to South Korea)`` student- soldier generation who were born between 1917-1923 and chose the ``South`` during the eight years after the liberation, especially those of the important ``Wollammin`` student- soldier generation such as Jang Jun-Ha, Kim Jun-Yeop, Seon Woo-Hui, Kang Won-Yong.

국학, 국문학, 국사학과 세계사적 보편성 : 1970년대 비평의 한 기원

김건우(Kim Kun-Woo) 한국현대문학회 2012 한국현대문학연구 Vol.0 No.37

It is generally accepted that 1970s' criticisms are best approached with the notion of the confrontation of Munhak-kwa-Jisung versus. Chanjak-kwa-Bipyung, but that approach could erase a lot of momenta latent in the intellectual history of 1970s. This thesis investigates the spiritual common basis of so-called 4.19 generation critics who had appeared on the scene not long before and soon would have their prime times. Dongil Cho's multi-volumed General History of Korean Literature (HanKukMunHakTongSa), which had been planned in mid-1960s and whose volume 1 was published in 1982, was indebted much to the rise of the theory of internal development and it is related debates about periodization in the circles of Korean History. This theory of internal development, mainly intended to overcome the colonial view of korean history(i.e. the notorious notions such as delay and heteronomy of korean history), was obsessed by method/attitude of the historiography. Hyun Kim's The History of Korean Literature(HanKukMunHakSa) was also included in this discourse field. There was the leftist motifs in Yongseop Kim's studies that had empirically founded the theory of internal development, but Nakcheong Back tried to realize the motifs not by historiography but by literary criticisms. He adopted the theory of internal development between 1966 and 1969, and developed his own theories of Citizen Literature/National Literature on the basis of it. There underlied the nationalistic longings to discover the universal motifs of world history(or western history) in the paradigm of 4.19 generation's criticisms which had a long influence on korean literature from the late 1960s. Despite the fact that there also existed the lefitist motifs in that aspirings, nationalism itself could not avoid the kinship with the state ideology and we can visibly see their relation made real in the korean contemporary history. This shows that whether it being historiography or literary criticism, 4.19 generation's writing, regardless of being leftist or rightist, could not escape from the category of Koreanology and paradoxically could not break out of the universalistic spell. 1970년대 비평을 '문학과지성' 대 '창작과비평'이라는 하나의 대립구도로 접근하는 오랜 통념은 당대 지식사의 수많은 계기들을 사상한다. 본고는 4.19세대로 묶일 수 있는, 1960년대 중반 이후 등장하여 얼마 되지 않아 그들의 시대를 가지게 되는 비평가들의 '공통된' 정신적 기반을 논하려는 것이다. 1960년대 중반부터 기획되어 1982년에 첫 권을 내게 된 조동일의 『한국문학통사』는 국사학계의 '내재적 발전론'의 대두와 이와 관련된 시대구분 논쟁에서 힘입은 바 컸다. 국사학계의 내재적 발전론이 식민사학의 정체성론, 타율성론을 극복하기 위해 성립된 것이었던 까닭에, '근대의 자생적 기점'을 거론하는 이러한 관점은 역사서술 방식/태도에 대한 강박으로부터 출발한 것이었다고 할 수 있다. 김현의 『한국문학사』 역시 이 자장에 포섭되었음은 물론이다. 내재적 발전론을 실증적으로 확립한 역사학자 김용섭에게서부터 사회경제사학 특유의 좌파적 계기가 존재했는데, 백낙청은 그 좌파적 계기를 문학사 서술이 아닌 비평을 통해 구현했다. 1966년에서 1969년 사이에 백낙청은 내재적 발전론을 수용하고 이에 입각해 이후 시민문학론, 민족문학론을 발전시켜 나가게 된다. 1960년대 후반부터 비롯되어 이후 오랜 기간을 통해 영향력을 행사한 4.19세대 비평 패러다임의 근저에는, 세계사적(서구적) 보편성을 한국사에서 찾고자 했던 민족주의적 열망이 자리하고 있었다. 이런 열망 속에 좌파적 계기가 존재했음에도 불구하고, 민족주의 자체가 국가 통치 이데올로기와 접점을 지니고 있을 수밖에 없었다는 점은 현대사를 통해 실증되는 사실이다. 이는 1970년대에 진입하던 4.19세대에 있어 문학사가 되었든 비평이 되었든, 좌우를 막론하고 소위 '국학'의 범주를 벗어날 수 없었음을, 역설적으로 보편성의 강박에서 풀려날 수 없었음을 의미하는 것이기도 하다.

운명과 원한

김건우(Kim Kun Woo) 서강대학교 인문과학연구소 2018 서강인문논총 Vol.0 No.52

1943년 일본과 조선의 대학생들에게 징병이 예고되었을 때, 조선인 학생들의 반응은 일본인 학생들과는 큰 차이를 보였다. 일본인 학병들에게도 자신의 죽음에 이유가 필요했지만, 대체로 그들은 자신들이 처한 상황을 ‘운명’으로 받아들였다. 이와 달리 조선인 학생들은 ‘국가를 위한 죽음’을 받아들이지 못했고, 이에 따라 도피, 자기 방기 등 온갖 형태의 이상 반응을 보였다. 조선인 학생들은 자신의 처지를 비관했고, 그 모든 고통을 조상과 윗세대에 대한 ‘원한’의 형태로 간직했다. 그런데 태평양전쟁기 일본인 학생들에게 존재하던 ‘국가’라는 매개항이, 전쟁이 끝난 후 조선인들에게도 부활한다. 그 부활한 국가란 어떤 성격의 국가인가. ‘원한’을 세대론적으로 장착하고, 욕망을 투사할 새 ‘대상’은 어떤 성격을 지녀야 하는가. 이것은 좌우 이념의 문제이기도 했다. 문학사를 놓고 이야기할 때, 그 대답의 자리에 선우휘와 이병주가 있었다. 선우휘와 그의 소설 『불꽃』의 모델 신상초는 대한민국이라는 국가를 자기 운명과 등치시킬 수 있었다. 이와는 달리, 이병주와 그의 모델 황용주가 남한에서 자신의 운명을 발견할 방법이란 없었다. 이념의 경계에 서성이는, ‘이방인’으로 살아가는 것이 그들이 할 수 있는 전부였다. When the empire of japan announced in 1943 that the military draft would be enforced on college students, the reactions of korean students were different from those of japanese students. Japanese students mostly accepted their situations as ‘fates’, though they also felt the need of excuses for their dying. But korean students could not embrace ‘dying for the sake of the state’, and exhibited various types of abnormal reactions such as escape, self-abandonment, etc. They felt deeply hopeless and desperate about their situations, and kept these feelings inside as a form of resentment against their ancestors. But a state - a kind of mediator - which had existed for Japanese students during the pacific war, was resurrected after the war for Korean students too. What was supposed to be the characteristic of this state resurrected? What characteristic should be attached to this new ‘object’ toward which they would project their desires keeping resentment in mind as a collective emotion of the student soldier generation? This question was also concerned with rightist and leftist ideologies. Seen from the perspective of korean literary history, Sun Woo-Hui and Lee Byung-Joo were two versions of the answer to this question. Sun Woo-Hui and Shin Sang-Cho, the model of Sun"s short story Flowers of Fire identified their fates with the fate of the state, ie. the republic of korea. On the contrary, Lee Byung-Joo and his model, Hwang Young-Joo could not find their fates in south korea. There was nothing they could do except wavering along the border of ideologies and living as ‘aliens’.

한국판 우울과 신체 증상 평가 척도(Depression and Somatic Symptom Scale, DSSS)의 신뢰도와 타당도

김건우,홍진표,박승진,최지혜,최혜라,Kim, Kun-Woo,Hong, Jin-Pyo,Park, Seung-Jin,Choi, Ji-Hye,Choi, Hye-Ra 대한불안의학회 2011 대한불안의학회지 Vol.7 No.1

Objectives : We examined the reliability and validity of the Korean version of the Depression and Somatic Symptom Scale (DSSS) in Korean patients with depressive symptoms. Methods : Participants were 55 outpatients diagnosed with major depressive disorder, a depressive episode of bipolar I disorder, somatoform disorder, panic disorder, generalized anxiety disorder, or post-traumatic stress disorder according to the DSM-IV criteria. We assessed them using the Korean versions of the DSSS, Hamilton Depression Rating Scale (HDRS), and Quick Inventory of Depressive Symptomatology Self Report (QIDS-SR). Results : The Korean version DSSS had a Cronbach's alpha of 0.90. Moreover, each item's correlation with the total score was statistically significant (r=0.24-0.71, p<0.01). The test-retest correlation coefficient (r=0.83, p<0.01) was relatively high, and the DSSS correlations with the HDRS and QIDS-SR were 0.77 and 0.74, respectively. Conclusion : These results demonstrate that the Korean version of the DSSS could be a reliable and valid tool for screening and assessing depressive patients. The Korean version of the DSSS will be a useful tool for screening both depressive and somatic symptoms in Korea.

생명보험회사의 경영효율화에 관한 소고 : 신설 K생명보험회사를 중심으로 Case in k Life Insurance Company

손성호,김건우 대구산업정보대학 1994 논문집 Vol.8 No.-

There have remarkably appeared more serious problems in profits and safety of the newly established life insurance company according to the recent change in domestic and foreign finance environment. The purpose of this study, therefor, is to suggest the following methods for effective managing the life insurance company. First, the reduction of working expenses can be accomplished by choosing a proportional allowance system of canvassers and operating branch agencies of the life insurance company on the basic of 3.3 indoor-service employees for its each agency. Second, it is required to mainly sell the middle or long-term security products so as to achieve the solvency. Third, more intensive study must be promoted on such advanced investment technologies as portfolio selection, capital assets pricing model(CAPM) and Argitrage pricing Model(APM). fininally it is not only necessay to make its underwriting more stable but also to train and educate its specialized personnel by means of both improved business of insurance contract department and strict contract selection.

동해·삼척지역 신라 횡혈계 묘제의 등장과 의미

김건우 ( Kim Kun-woo ) 강원사학회 2022 江原史學 Vol.- No.39

이 글에서는 동해·삼척지역에서 조사된 횡혈계 묘제를 분석하고, 횡혈계 묘제의 등장과 그 의미에 대하여 살펴보았다. 횡혈계 묘제는 내부구조의 속성 조합을 통해 8개의 형식으로 분류 할 수 있다. 각 형식은 변화양상을 토대로 4단계로 설정할 수 있으며, 출토된 토기류(고배, 개, 부가구연대부장경호)로 보아 중심연대는 6세기 초엽에서 7세기 말엽으로 편년된다. 동해·삼척지역은 原三國時代에서 三國時代로 이어지는 묘제가 아직까지 확인된 바가 없다. 다만 2세기 전엽부터 5세기 전엽까지 존속한 취락유적과의 관계를 통해 횡혈계 묘제의 등장을 추론할 수 있다. 취락유적은 기존의 연구에서 ‘悉直國’의 문화로 파악하고 있고, 삼국사기를 살펴보면 간접지배의 형태로 신라와 관계 맺었을 가능성이 크다. 간접지배 관계에서 점진적인 변화 양상이 수반되지 않은 채 갑작스럽게 등장한 횡혈계 묘제는 신라와 밀접한 관련성을 가진 신흥 집단의 출현을 나타낸다. 가장 이른 시기에 조영된 동해 구호동고분군과 추암동고분군은 신라의 간접지배에서 직접지배로의 전환을 나타내며, 동해·삼척 지역은 이를 위한 전초기지로 볼 수 있다. 아울러 505년(지증왕 6) 직접지배의 산물인 悉直州의 설치와 軍主의 파견은 동해·삼척지역에서 압도적인 위치를 가지는 고분군이 확인되지 않는 까닭으로 볼 수 있다. In this article analyzed the Corridor Entrance Type Burial System in the Donghae and Samcheok Area and looked into the appearance and meaing of the Corridor Entrance Type Burial System. The Corridor Entrance Type Burial System can be classified into 8 types through the combination of attribute of the internal structure. Each type can be set in 4 stages based on the change aspect, and the central era is from the beginning of the 6th century to the end of the 7th century based on the earthenware excavated(mounted dishes, half-spherical lids, the long-necked jars with stand). In the Donghae and Samcheok area, there are not has been confirmed yet to be connected burial system from the Proto-Three Kingdoms Period to the Three Kingdoms Period. However, it is possible to infer the emergence of Corridor Entrance Type Burial System through the relationship with the settlements that continued from the early 2nd century to the early 5th century. The settlements have been identified as the culture of 'Siljik-guk(悉直國)' in previous studies, and if you look at the Samguksagi(三國史記), it is highly likely that they had a relationship with Silla in the form of indirect rule. The Corridor Entrance Type Burial System, which sudden appeared without any gradual change in the indirect control relationship, is represents the emergence of a new group closely related to Silla. The Guho-dong and the Chuam-dong tomb clusters in Donghae, built at the earliest period, represent the transition from indirect control to direct control of Silla, and Donghae Area can be seen as outposts for this. In addition in 505(year 6 of Jijeung maripgan) as a result of direct rule the installation of Siljik-ju(悉直州) and the dispatch of ruler can be attributed to the reason that the tomb clusters with an overwhelming position of the Donghae and Samcheok area are not identified.

대고객 외환시장의 거래비용 구성요소

The question of through what mechanism private information is reflected on the exchange rate is a major topic of FX market microstructure research from the perspective of price discovery in FX market. Lyons (1997) points out that “private information in the interbank FX market is attributable more to information obtainable through the flow of customer orders than to information superiority on macro variables.” Most previous researches on this topic have been largely limited to interbank markets. Through empirical analysis on interbank markets, previous foreign researches, including those by Lyons (1996), Evans and Lyons (2002) and Payne (2003) as well as domestic researches by Seon and Eom (2006, 2010b), suggest evidence that the asymmetric information cost is reflected on the exchange rate for interbank markets. However, since the FX market maintains a two-tiered structure consisting of the interbank market and the customer market, analysis on the interbank market alone presents limitations in understanding the overall process by which private information is reflected on the exchange rate determined in the FX market. By examining whether the asymmetric information cost is included in the composition of trading cost of customer exchange rate in the won/dollar customer FX market, this study seeks to test whether the 3-stage hypothesis of Osler et al. (2011) stands true in the won/dollar FX market. If the asymmetric information cost is included in the trading cost of the customer exchange rate, such would indicate that private information included in the customer order flow is incorporated into the exchange rates in the customer market. However, if the asymmetric information cost is not included in the customer exchange rate, then it would mean that private information included in customer order flow is reflected on exchange rates in the interbank market as championed by the 3-stage hypothesis suggested by Osler et al. (2011) rather than on the customer market. Such a research is expected to improve the degree of understanding on the mechanism through which private information possessed by customers is reflected on the exchange rate, and how price consistent with the “3-stage price discovery theory” of Osler et al. (2011) to a certain extent. According to this theory, while the customer dealer may engage in trades with customers who possesses private information, such private information is not reflected on the exchange rate offered by the dealer to the customer but is rather reflected later on the interbank exchange rate. In other words, price discovery is made in the interbank market rather than in the customer market. Second, among the components that comprise the trading cost for the FX fee, the inventory holding cost manifests neither in any of the partial samples nor in the overall sample. Such non-appearance of the inventory holding cost in the customer transactions seems to be attributable to high liquidity in the Won/Dollar interbank market and low risk of inventory holding, which is itself attributable to the fact that most trades are performed through the electronic brokerage system. Third, among the components that make up the trading cost for the FX fee, the order processing cost manifests clearly and differs depending on the order size, customer type, and time of day. An analysis of the order processing cost based on trade size-namely, large, medium, and small size of trades-shows an inverse relationship between the size of trades and the order processing cost. This phenomenon is thought to be attributable to the customer dealer’s effort to elicit large scale transactions and thereby maximize profits from fees. In addition, the analysis based on customer type-namely financial firms, large firms, and small and medium firms- shows that the order processing cost of financial firms is larger than that of large firms and small and medium firms. This phenomenon seems to be attributable to the fact that in the case of financial firms, the size of orders is relatively small and higher percentage of transactions is processed at certain times of the day when the order processing cost is relatively high. Meanwhile, with regards to time, the order processing cost peaks during the earlier times of the market and gradually declines afterwards. Such phenomenon of higher order processing cost during the early market is thought to be due to the smaller average size of orders during this period. Finally, the components that make up the trading cost with regards to the cover rate are either statistically insignificant or have small values of lower than 0.10 Won, which is the minimum price unit, and are thus economically insignificant. This implies that component elements, such as the asymmetric information cost, the inventory holding cost, and the order processing cost, are not reflected on the cover rate offered by the interbank dealer to the customer dealer.
