The reconstruction forces of Baekje asked Pung-Jang to return to the homeland as the pivot for securing Baekje dynasty’s legitimacy. Pung-Jang left Wae (Japan) in September 661, and arrived in Baekje in December. During that time, however, there was some political changes within the reconstruction forces--Boksin eliminated Dochim. Thus, he return seemed in vain. His succession to the throne was threatened because of the political upheaval. He managed to compromise with Boksin, and succeeded the throne in May 662, but he remained asa nominal king without real power. However, Boksin, though he seized the power, was embroiled in the political chaos. Baekje lost most key military bases by Shilla-Tang Combined Forces such as Jira-fortress, Yun-fortress, Deasan-stockade, Sajeong-stockade, and Jinhyeong-fortress in July 662 and Neasaji-fortress as well in August. At this, Boksin sought to settle the political disturbance by the capital to Pi-fortress(Gimje) in December 662. In February 663, however, he lost the key bases in the south such as Geoyeol-fortress, Geomul-fortress,Sapyeong,andalsoDeokan-fortress, one of the Five-Bangs. He was forced to retreat to Juryu-fortress(Buan) as the new capital was threatened. As the political maneuver to move the capital city to Pi Fortress failed, Boksin power was weakened. Taking the opportunity, King Pung began involving in the military affairs and strengthened his political power to the extent to raise a formal issue of ‘Boksin’s sin’. Finally, he could remove Boksin in June 663. In the end, the discord between King Pung and Boksin come to an end by a political revolt. But it was not a peaceful period to be engaged in the internecine struggles. King Pung managed to restore his legitimacy as king, but he didn"t have enough time to fight against the Shilla-Tang Combined Forces.
FMEA에서 공통원인고장이 포함될 경우의 고장원인에 대한 위험평가 절차
김병남 ( Byung Nam Kim ),권혁무 ( Hyuck Moo Kwon ),홍성훈 ( Sung Hoon Hong ),이민구 ( Min Koo Lee ) 한국품질경영학회 2018 품질경영학회지 Vol.46 No.2
Purpose: A risk evaluation procedure is proposed for common failure causes in FMEA(Failure Mode and Effects Analysis). The conventional FMEA does not provide a proper means to compare common failure causes with other failure causes. This research aims to develop a risk evaluation procedure in FMEA where common failure causes and other failure causes exist together. Methods: For each common failure cause, the effect of each combination of its resulting failures is recommended to be reevaluated considering their interactive worsening effect. And the probability that each combination of failures is incurred by the same common cause is also considered. Based on these two factors, the severity of each common cause is determined. Other procedures are similar to the conventional method. Results: The proposed procedure enables to compare and prioritize every failure cause. Thus, the common causes, each of which incurring two or more failures, and other causes, each of which is corresponding to one failure, can be fairly compared. Conclusion: A fair and proper way of comparing the common failure causes and other causes is provided. The procedure is somewhat complicated and requires more works to do. But it is worth to do.
층상구조기반의 리튬이차전지용 양극 활물질에 관한 특허정량분석
김병남 ( Byung Nam Kim ),임용환 ( Yong Hwan Lim ),이철태 ( Chul Tae Lee ) 한국공업화학회 2015 공업화학 Vol.26 No.3
This paper discusses quantitative analyses of patents published for cathode active materials for lithium secondary batteries based on layer structure. Numbers of the patents analyzed were 356, 1628, 2915, 439, and 611 for Korea, USA, Japan, Europe, and PCT (WO), respectively. Trends of improved technologies and alternative technologies concerning lithium cobalt, from 1991 to 2012 were examined and the patent shares distribution of each principal countries about lithium secondary battery technologies were also scrutinized. The number of patents for the mixed structure technology and next-generation lithium secondary battery technology increased numerously in 2000. Particularly in 2005, lots of patents were also published and SANYO (34.5%), SONY (17.5%), LG (7%), and SAMSUNG (5.5%) possessed leading patent applicants. Finally, the research focus on cathode active materials for lithium secondary batteries was confirmed by bubble chart distributions for component-by-step process.
층상구조기반의 리튬이차전지용 양극 활물질에 관한 특허정성분석
김병남 ( Byung Nam Kim ),임용환 ( Yong Hwan Lim ),이철태 ( Chul Tae Lee ) 한국공업화학회 2015 공업화학 Vol.26 No.3
We have quantitatively analyzed 1,294 effective patents on “Quantitative Analysis of Patents Concerning Cathode Active Materials for Lithium-Ion Secondary Batteries Based on Layer Structure” from Korea, USA, Japan, Europe and PCT (WO). The importance of technological and patent values of the aforesaid patents were evaluated by the factors shown in Table 1, and 104 major and 20 core patents were selected in compliance with the evaluation from the patents. The technological flow chart over time regarding the selected major and core patents was prepared, and the applying time and development process of patents, as well as the position of core patents were established on the time scale investigated. Finally, the differentiation plans and patent avoidance strategies for the next technology development, in comparison with the technologies of patents already applied and registered, were suggested.

『삼국사기』「백제본기」에는 성왕의 북진(551) 이전부터 한강 유역과 관련된 여러 지명들이 나타나는 바, 성왕 즉위년(523)의 '패수(예성강)', 성왕 7년(529)의 혈성(강화도)과 왕봉현 · 달을성현(경기도 고양), 성왕 18년(540)의 우산성(황해도 금천군 우봉면), 성왕 26년(548)의 독산성(경기도 포천) 등 한강 유역 일대를 둘러싸고 백제와 고구려가 공방을 벌인 사실을 보여준다. 이는 이들 지역의 전략적 가치를 재인식 시켜줌과 동시에 성왕 초기에 이미 한강 이북 지역을 백제가 점유하였던 사실을 확인시켜 준다. 하지만 성왕(523~554) 시기의 북방 영역은 전대인 동성왕(479~501)~무령왕(501~523) 시 기보다도 오히려 후퇴한 모습을 보인다. 왜냐하면 이 시기 고구려가 혈성과 왕봉 · 달을성현을 빼앗고, 독상선을 공격하는 등 한강 이북 지역에 근접하였기 때문이다. 그럼에도 불구하고 백제가 패수나 오곡(황해도 서흥) 등 한강 이북을 넘어 공격한 것은, 백제의 고구려 공격이 한강 넘어 상당히 깊게 진행되었음을 뜻하며, 달리 표현하면 백제와 고구려의 경계선이 예성강 이남~한강 이북 사이에서 유동적으로 유지되었음을 뜻한다. According to the records of "Baekjebonggi"(百濟本紀) of Samguk Sagi(三國史記), before northern expansion of King Seong(551), Baekje and Goguryo had done heated offensive and defensive battles in the region of Han River Basin, including Paesu(浿水 ; the Yeseong River) at the time of King Seong's accession to the throne(523), Hyeolseong(穴城 ; Ganghwado), Wangbonghyeon(王逢縣) and Daleulseonghyeon(達乙省縣 ; Goyang in the province of Gyeongi) in the 7th of King Seong(529), Usanseong(牛山城 ; Ubong-myeon, Geumcheon-gun in the province of Hwanghae) in the 18th of King Seong(540), Doksanseong(獨山城 ; Pocheon in the province of Gyeongi) in the 26th of King Seong(548). This shows that Baekje realized that Han River region had strategic importance and Baekje had already occupied the northern part of Han River at the early time of King Seong. At the early time of King Seong, the northern territory, however, seems to retreat than in the period between King Dongseong(東城王) and Kiing Muryeong(武寧王). At this time Goguryeo took Hyeolseong and Wangbong · Daleulseonghyeon and attacked Doksanseong in the northern areas of Han River. Nevertheless, Baekje attacked Paesu and Ogok(五谷) beyond North Han River. This means that the border of Baekje and Goguryeo was formed somewhere in between southern Yeseong river and North Han River.
