        The object of thes research is to lucidate the clinical effects of Gami-Cheongshimyeonjayeum on the anti-allergic and gimmune response to rats and mice. The obtaind results of Gami-Cheongshimyeonjayeum administration are as follows : 1. The cytotoxic index increased slightly at over concentration $1{\times}10^{-2}/ml$, but it is thought that the cytotoxic effect show no significant value under the concentration $1{\times}10^{-3}/ml$. 2. Gami-Cheongshimyeonjayeum water extract seems to suppress the leakage volume of Evans blue to decrease the vascular permeability. 3. Gami-Cheongshimyeonjayeum show the inhibitory effect of footpad edema. 4. Protein leakage is inhibited by the administration of Gami-Cheongshimyeonjayeum. 5. The delayed type hypersensitivity to SRBC is suppressed at the 24hours after the administration of Gami-Cheongshimyeonjayeum on the experimental group 1, 2. 6. Hemolysin and hemagglutinin titer, and RFC increase to bulid up the immune function.

        This study was carried out to investigate the effects herbal extracts on the skin inflammatory reactions. Among the herbal ingredients of herbal extracts, ethanol extract of Glycyrrhizae Radix showed potent radical scavenging activity, more than 86$\%$ at a concentration of 0.01$\%$, tested by DPPH(I,1-diphenyl-2-picryl-hyrazyl) method. And ethanol extract of Aurantii Immaturus Fructus inhibited the lipopolysaccharide-induced release of nitric oxide(NO), 99$\%$ at 50㎍/㎖, by the macrophage RAW 246.7 cells. In addition, the ethanol extracts of Sophorae Radix, Glycyrrhizae Radix showed antibacterial activities on Propionibacterium acnes that causes acne, Sophorae Radix, Glycyrrhizae Radix and Aurantii Immaturus Fructus on Corynebacterium xerosis that cause osmidrosis axillae, Glycyrrhizae Radix and Aurantii Immaturus Fructus on Staphylococcus aureus that was reported to cause impetigo and atopic disease. Taken together, I expect that herbal extracts may be used as a drug for treatment on skin inflammation.

        실리카의 이온성 액체 기능화가 메탈로센 담지촉매의 에틸렌 중합 거동에 미치는 영향

        이정숙 ( Jeong Suk Lee ),이창일 ( Chang Il Lee ),고영수 ( Young Soo Ko ) 한국공업화학회 2016 공업화학 Vol.27 No.1

        Three amorphous silicas and SBA-15 were employed as supports, which were capable of confining ionic liquid (IL) and metallocene in the nanopore. Ionic liquid functionalized silica was prepared by the interaction between the chloride anions of 1,3-bis(cyanomethyl) imidazolium chloride and the surface OH groups. Metallocene and methylaluminoxane (MAO) were subsequently immobilized on the ionic liquid functionalized silica for ethylene polymerization. The metallocene supported on ionic liquid functionalized XPO-2412 and XPO-2410 having a larger pore diameter compared to SBA-15 showed higher activity than that of using supported catalyst without ionic liquid functionalization. However, the activity of metallocene supported on SBA-15 decreased after ionic liquid functionalization, suggesting that the diffusion of ethylene monomer and cocatalyst to the active site of nanopore was restricted during ethylene polymerization. This could be resulted from significant reduction of the pore diameter due to the immobilization of ionic liquid and (n-BuCp)2ZrCl2 and MAO. The effect on polymerization activity in accordance with the concentration of hydroxyl groups on the surface was also investigated. The polymerization activity increased as the concentration of hydroxyl groups on amorphous silica increased. The polymerization activities of metallocene supported on silica showed the similar trend after ionic liquid functionalization.

        표면 기능화된 Micelle-Templated Silica 나노세공 내 메탈로센 담지 및 에틸렌 중합

        이정숙(Jeong Suk Lee),임진형(Jin Heong Yim),고영수(Young Soo Ko) 한국고분자학회 2012 폴리머 Vol.36 No.1

        메조포러스 물질의 표면을 post-synthesis grafting method를 통해 표면을 기능화시킨 후 (n-BuCp)2ZrCl2/ methylaluminoxane(MAO)를 담지하여 에틸렌 중합을 실시하였다. 아민기와 시안기를 가지는 유기실란 N-[(3- trimethoxysilyl)propyl]ethylenediamine(2NS), 4-(triethoxysilyl)butyronitrile(1NCy), 1-(3-triethoxysilylpropyl)-2- imidazoline(2NIm)는 메조포러스 물질의 표면 기능화에 사용되었다. SBA-15/2NS/(n-BuCp)2ZrCl2촉매 담지시 MAO의 양이 증가할수록 Zr 함량은 감소하였고 Al 함량은 증가하였다. 에틸렌 중합 활성은 MAO의 양이 증가할 수록 급격히 증가함을 볼 수 있었다. 담지시간이 6시간일 때 가장 높은 활성을 보였다. 유기실란의 종류에 따른 활성 차이는 SBA-15/2NS/(n-BuCp)2ZrCl2 > SBA-15/2NIm/(n-BuCp)2ZrCl2 > SBA-15/1NCy/(n-BuCp)2ZrCl2 순으로 감소하였다. 아민기를 두 개 갖는 2NS와 2NIm은 아민기를 하나 갖는 1NCy보다 (n-BuCp)2ZrCl2와 더 강하게 상 호작용을 한다. 따라서 촉매 내 질소와 Zr함량이 증가할수록 활성은 증가하였다. A functionalization of mesoporous materials with organosilane was carried out via a post-synthesis grafting method and (n-BuCp)2ZrCl2/methylaluminoxane (MAO) as subsequently immobilized on the functionalized mesoporous materials for ethylene polymerization. Organosilanes having amine, cyano or imidazoline group such as N- [(3-trimethoxysilyl)propyl]ethylenediamine (2NS), 4-(triethoxysilyl)butyronitrile (1NCy), 1-(3-triethoxysilylpropyl)-2- imidazoline (2NIm) were used for the surface functionalization of mesoporous materials. In the SBA-15/2NS/(n- BuCp)2ZrCl2 catalyst preparation, the amount of MAO in feed increased with an decrease in the Zr content of the supported catalyst, and Al content in the supported catalyst increased. The ethylene homopolymerization activity of SBA-15/2NS/(n-BuCp)2ZrCl2 dramatically increased as the amount of MAO in feed increased. Furthermore, when the immobilization time was 6 hrs, SBA-15/2NS/(n-BuCp)2ZrCl2 showed the highest activity. The activities of supported 2NS-, 1NCy-, 2NIm-functionalized catalysts decreased in the following order, SBA-15/2NS/ > SBA-15/2NIm/ > SBA- 15/1NCy/(n-BuCp)2ZrCl2. 2NS and 2NIm which have two amine groups per silane molecule were shown to interact with (n-BuCp)2ZrCl2 strongly compared to 1NCy which has one amine group. Thus, the activities increased with an increase in the nitrogen and the Zr content of the supported catalysts.

The purpose of the study is to present implications for the management performance and improvement of enterprises through the study of the simplicity of meals, individual values, inhuman relationships, attitude formation, awareness and solitary eating behaviors. The research method was investigated by the judgment sampling method. The collected effective samples were validated using a confirmed factorial analysis to ensure the validity of the discriminatory validity and the internal validity of the convergent validity. First of all, the company should provide information to the people who eat alone to A recognize the simplicity of their meals. Second, we should ensure that the individual values of the Honbab people can be formed through various promotional strategies that can lead to the formation of attitudes. Third, companies should pursue diverse event strategies that can lead to the formation of attitudes of the people of the Honbab family. Fourth, event development such as the provision of a very special service for customers only will have to be conducted when visiting the stores of the Honbap people. Finally, companies should focus on promoting the convenience, convenience, and time-consuming advantages of eating alone through a variety of marketing, and strive to increase their customers.

        1,3-Dipolar cycloaddition 반응을 통해 기능화된 carbon nanotube 표면 위에 균일계 촉매 담지 및 에틸렌 중합

        이정숙 ( Jeong Suk Lee ),이세영 ( Se Young Lee ),이진우 ( Jin Woo Lee ),고영수 ( Young Soo Ko ) 한국화학공학회 2016 Korean Chemical Engineering Research(HWAHAK KONGHA Vol.54 No.4

        In this study, CNT functionalized with pyrrolidine ring via 1,3-dipolar cycloaddition reaction with various amino acid and aldehyde was synthesized. Metallocene was subsequently immobilized on the functionalized CNT and CNT/polyethylene composite was prepared via in-situ ethylene polymerization. The polymerization activities of metallocene supported on CNT functionalized with glycine and benzaldehyde (Gly+BA-CNT) were similar to those of metallocene supported on CNT functionalized with N-benzyloxycarbonylglycine and paraformaldehyde (Z-Gly+PFA-CNT) although its Zr content was lower than that of Z-Gly+PFA-CNT. In the case of metallocene supported on Z-Gly+PFACNT, the even distribution of active sites hindered the diffusion of ethylene monomer and cocatalyst MAO due to steric hindrance during ethylene polymerization. Compared to polyethylene produced from homogeneous metallocene catalysts, CNT/PE composites had a higher initial degradation temperature (T_{onset}) and maximum mass loss temperature (T_{max}). It suggests that pyrrolidine functionalized CNT is uniformly dispersed and strongly interacted with the PE matrix, enhancing the thermal stability of PE.
