김진식,최성근,이정현,공영건,Kim, Jin-Sik,Choi, Sung-Keun,Lee, Jung-Hyun,Kong, Young-Kun 대한화학회 2007 대한화학회지 Vol.51 No.3
1,1'-Bis(dimethylsilyl)ferrocene과 다양한 aldehydes를 소량의 Ni(PEt3)4 촉매하에서 반응시켰을 경우 hydrosilylation 반응에 의한 비고리형의 monohydrosilylation 된 생성물이 얻어졌다. 그러나 촉매를 Ni(PEt3)4 대신에 (C2H4)Pt(PPh3)를 사용한 경우에는 고리형의 double silylation 된 6각 고리 생성물이 얻어졌다. 특히 Pt 촉매하에서 4-cyanobenzaldehyde silylation 반응은 double silylation 된 5,6-ferrocenylene-1,1,4,4-tetramethyl-2-oxa-2-cyanophenyl-1,4-disilacyclohexane의 결정을 얻었다. The reaction of 1,1'-bis(dimethylsilyl)ferrocene with various aldehydes in the presence of a catalytic amount of Ni(PEt3)4 lead to the acyclic products by monohydrosilylation. The same reaction in the presence of a catalytic amount of (C2H4)Pt(PPh3)2 leads to the different cyclic six membered ring compound by double silylation. Platinum catalyzed double silylation of 4-cyanobenzaldehyde was generated 5,6-ferrocenylene-1,1,4,4,-tetramethyl-2-oxa-2- cyanophenyl-1,4-disylacyclehexane which was crystallized to have crystal structure.
백금/니켈 촉매를 이용한 1,1'-Bis(dimethylhydrosilyl)ferrocene과 Alkynes, Alkenes의 선택적 Hydrosilyation 반응
김진식,공영건,Kim, Jin-Sik,Kong, Young-Kun 대한화학회 2010 대한화학회지 Vol.54 No.1
The reaction of 1,1'-bis(dimethylhydrosilyl)ferrocene with alkynes in the presence of a catalytic amount of ($C_2H_4$)Pt$(PPh_3)_2$ leads to the acyclic mixture of monohydrosilylated and/or dihydrosilylated compounds. But the analogous reactions in the presence of Ni$(PEt_3)_4$ catalyst yield monohydrosilylated compounds or dihydrosilylated products. The monohydrosilylated products were generated from the reactions of alkenes with the silylated ferrocene using nickel catalyst. 1,1'-Bis(dimethylhydrosilyl)ferrocene과 alkynes의 반응에서($C_2H_4$)Pt$(PPh_3)_2$ 촉매경우는 monohydrosilylation과 dihydrosilylation된 비고리화합물의 혼합물이 주로 생성되었고, Ni$(PEt_3)_4$ 촉매 경우는 monohydrosilylation 생성물 또는 dihydrosilylation 생성물만 얻어지는 선택적인 반응을 하였다. 그리고 Alkenes의 반응에서도 monohydrosilylation된 화합물을 얻었다.

Place names are generally composed of first half and second half, whether the originality of those names comes from Korean or Chinese. The first half, modifying the second half, represents the naming flexibility of the name, while the second half of the name points out its directive object, which refers to a branch of the name. For example, 'Myeong' in 'Myeongryang' and 'No' in 'Noryang' represent their naming flexibility while 'Ryang', constituting the second half, points out the name's directive object. The purpose of this study was to investigate the etymology of place names, 'Myeongryang' and 'Noryang', by figuring out the meanings of those two elements. In order to search for the meaning of the second half, 'Ryang', other examples presented in the related literature have been examined. The finding indicated that 'Ryang' means 'dol', or 'do', which refers to 'moon(door)'. Furthermore, it is found out that the meaning of 'Ryang' has been transferred from 'dol' or 'do' to 'moon(door)', furthermore, to the straits. Upon looking into the origins of those names on the field, it is interpreted that 'Myeong Ryang' has been meant as a door in which huge and rough waves cry out, and 'No Ryang' has been meant as a door in which huge and rough waves rise up.
설계사무소의 BIM 운영을 위한 LMS(Library Management System) 프레임워크 개발
김진식,김연수,마영균,Kim, Jin-Sik,Kim, Yeon-Soo,Mha, Young-Kyun 한국BIM학회 2013 KIBIM Magazine Vol.3 No.4
In order to boost productivity and efficiency of architectural design, architect accumulates materials and details which are repeatedly used. According as introduction and application of BIM (Building Information Modeling) have proliferated, a number of data are being produced. BIM data constructed in a stage of architectural design reduces repetitive works of design and can be used in estimate and construction, maintenance. BIM library gathered these data are able to enhance participants collaboration and design improvement. Library is a vital factor in BIM and a number of libraries are needed as BIM introduction and application have proliferated in architecture industry. However, BIM Library establishment and related research development are incomplete. And specific standard setting and institutional environment for BIM library building have not been achieved. As such a vast amount of information are generated but there is no systematic plan and reuse frequency is low. So it is necessary to build system for effective data sharing and operation management. In this study, through establishment of BIM standard system and construction of management environmental system, it has an object in view for developing framework which can efficiently manage various libraries happened in BIM architectural design field.

For waste water processing facilities distributed throughout Korea, design F/M ratio, actual operation F/M ratio, design SRT and actual SRT by processing capacity and processing method were compared to review a design application parameter and to draw an operation parameter value right for the environment in Korea. For design F/M ratio by processing capacity and SRT, 0.1~0.3kg BOD/kg MLSS·day and 10~30 day were applied regardless of capacity, but operation F/M ratio of actual waste water processing facility was 0.1 ~0.16kg BOD/kg MLSS·day, and average SRT was in the range of 15~25 days. And, in the case of design F/M ratio by a processing method, SBR system was being designed and operated lower than media or active sludge method. It is estimated that as SBR method is operated in extended aeration, which is operated by high LMSS, unlike the other method. When design and actual SRT are compared, in the case of media and active sludge type, wide range of 9.4~24.6 days was applied in design, but facilities were actually operated in 14~19 days. And, in the case of SBR system, while design SRT was long as 25.1~40.0days, operation SRT in SBR method in Korea was in average 32.1 days. Therefore, it is considered that this study can be used as an operation index of waste water operation facility based on the common operation standard of engineering methods applied in Korea, and as main operation parameter in development of logic to stabilize the process.

In this study, the method which could provide the proper operation condition for abnormal conditions at sewage treatment plant was suggested. For this analysis, the operating data of one year of 2011 has been collected from a sewage treatment plant for the media process. The abnormal condition was set up the winter season and the rainy periods. The multiple regression analysis was divided with 4 CASE according to the removal of outliers and the log transformation of variables. The criteria for operation conditions was set to 60% of water quality standards in CODMn, T-N considering the safety factor. As a result of this study, the proper operation condition for abnormal conditions at sewage treatment plant could be provided by multiple regression analysis. The sewage treatment plant that is collected operation data for this study was being operated within the proper operation range that is provided by multiple regression analysis.
