The survival of pancreas transplantation for treatments of patients with type Ⅰ diabetes mellitus has been improved especially in simultaneous pancreas and renal transplantation. Various innovations in immunosuppression, management of the pancreatic and exocrine secretion, recipient selection and HLA matching have been contributed to achieve a reasonable outcome in pancreas transplantation compared with other organ transplantation. Current improved graft survival has stimulated many centers in the world to start pancreas transplantation program. Since the first successful case of simulaneous pancreas and renal transplantation in my department in 1992, total 7 cases of pancreas transplantation was done, in which 2 cases of simultaneous pancreas and kidney transplantation was performed initially followed by 1 case of sequential pancreas transplantation after kidney transplant, 1 case of living donor pancreas transplant and 3 cases of pancreas transplantation alone.

Now, indeed, the renal transplantation is one of the essential tretment modality to cure the end-stage renal diseases. But the main limitation of successful renal transplantation is shortage of transplantable human organs. In this point of view, cadaveric organ transplantation is a way to cope with such an organ shortage. Recently we performed 27 cases of cadaveric renal transplantation despite of many obstacles caused by socio-cultural background of our people. In this article we reviewed the early results of cadaveric renal transplantations in Asan Medical Center and described the future prospects briefly.

Primary candidate for pancreas transplantation is patients with type Ⅰ diabetes mellitus of juvenile oneset. At present the patients selected for transplantation often have end stage renal disease, far advanced vascular disease and diabetic neuropathy. In these days, the survival of pancreas transplantation for treatments of patients with type Ⅰ diabetes mellitus has been improved especially in simultaneous pancreas and kidney transplantation. Various innovations in immunosuppression, management of the pancreatic ductal exocrine secretion, recipient selection and HLA matching have been contributed to achieve a reasonable outcome in pancreas transplantation compared with other organ transplantation. Current improved graft survival has stimulated many centers in the world to start pancreas transplantation program. Recently we successfully performed the first case of simultaneous pancreas and kidney transplantation in Korea. After 5 cases of pancreas transplantation in our department in type Ⅰ DM, we think that it is the time to review the pancreas transplantation to give an insight of this new field to our colleagues.

The duties of the restorative material are to bear up against stress and to protect reinforcement corrosion. So the restorative material are estimated by various kinds of strength, permeability and etc. But to evaluate performance of the restorative material accurately, it is necessary to estimate their reinforcement corrosion directly in environment of combined deterioration. In this study, to evaluate performance of restorative materials, we compare their properties in terms of compressive and bending strength and permeability of water and air with actual reinforcement corrosion like ratio of corrosion area, weight reduction and corrosion velocity of steel bar under environment of complex deterioration. The results showed that strength and permeability of restorative materials are similar but their reinforcement corrosions are very different. And there is a case that strength and permeability of restorative material are better than normal concrete but reinforcement corrosions are worse.

중금속 오염원을 제거하는 기술을 개발하고자 미나리를 도입하여 중금속 종류에 따른 적정 농도별로 중금속 흡수, 정화효율성 및 식물체내에서 중금속 축적과 이행과정을 조하하였다. 미나리를 이용한 중금속 정화효율성은 Cd의 경우 미나리 정식 6일 후 Artigicial solution 처리구와 문막 공업폐수처리구는 각각 53%, 73%의 정화효율성을 보였으며, Cu의 경우에는 각각 28%, 100%의 정화효율성을 보였다. 환경부에서 규정한 Cd의 청정지역 배출허용기준인 0.02 mg/L은 모든 처리구에서 10일 이후에 나타났으며, Cu의 기준농도인 0.5 mg/L은 Artificial solution 처리구의 경우 10일 이후, 문막 공업폐수 처리구는 3시간 이후에 나타났다. 또한 시간이 경과함에 따라 미나리내 중금속의 축적농도는 높아지는 경향을 보였으며, 처리구의 오염수 중금속 농도보다도 5~10배 이상 축적되었다. 미나리 식물체에 흡수된 중금속의 뿌리에서 지상부로의 이행율은 Artificial solution 처리구에서 Cd은 28%, 문막공업폐수 처리구에서 Cu는 28% 이행하였다. 중금속에 대한 미나리의 생육반응을 문막 공업폐수 처리를 제외한 모든 처리구에서 미나리 생장이 억제되는 결과를 보였다. 따라서 본 연구결과 미나리는 중금속 오염수의 중금속 정화를 위한 식물성화기술에 유용하게 활용할 수 있을 것으로 판단된다. The removal rate of heavy metals from the wastewater, the accumulation and translocation of heavy metals in plants after transplanting, and the responses of water celery growth with different wastewater treatments were investigated to determine the potential ability of green-remedlation with hydroponic culture of water celery. The removal rate and translocation of Cd, Cu, Ni and Pb from different wastewater to plants were compared with cultivation periods after transplanting. The removal rate of heavy metals from wastewater was different with each treatment, but increased with growing periods of water celery plants. The removal rate of Cd, Cu, Ni and Pb in Artificial solution, Artificial solution+EDTA, Munmark industrical wastewater, Jungsun minewater is ranged from 22 to 73%, from 28 to 100%, from 13 to 92% and from 41 to 100% at 6 days after transplanting, respectively. The translocations of Cd, Cu, Ni and Pb from roots to shoots in Artificial solution, Artificial solution+EDTA, Munmark industrical wastewater, Jungsun minewater are ranged from 14 to 28%, 8 to 30%, from 28 to 45% and from 2 to 15% at 12 days after transplanting, respectively. In plant growth responses, it appears to be inhibited the plant growth over all treatments excepts for Munmark industrial wastewater in these growing periods. Therefore the water celery might play a useful role in phytoremediation to clean up wastewater contaminated with Cd, Cu, Ni or Pb.

This study is for the purpose of examining effects related to duty stress & duty satisfaction due to Police of officers' Physical exercise participation, helping more efficient duty Performance, and positive self-formation. Furthermore, providing basic data that can be helpful to the improvement of police duty. The objects of the study were police officers who were taking part in education program in Police Comprehensive Academy, and the number of police officers who answered the questionnaire is 356 police officers, but data used for real analyzation consist of 300 police officers. The tools for the study were based on Ivancevich's duty stress model in order to measure stress. And also questionnaire used on Kim yoon hee, Kim mae ja, Jo kyung soon, Lee hart kyung's study was used as a complementary tool. The instrument for measuring duty satisfaction rate was developed by Paula. And I used the instrument based on questionnaire that was used by Ko hee soon, Park ki hyung, Kim bum sik, Lee jong kil, Lim bun jang, Jo young chang, Hackeman, Lawlar and Oldham's study. Data analysis is Processed statistically with SPSS/PC+, I Performed T-verification, ANOVA-verification in accordance with the purpose of study after getting the percentage and the real number in case of general characteristics of the objects, and examine an average and standard variation in case of duty satisfaction and duty stress rate. And I set an err rate to 0.5. I verificated co-relation between stress and duty satisfaction with Pearson Correlation Coefficient. The result of the study is as follows, The first, among sociological characteristic and external factor of duty satisfaction, The married is more significant statistically(p< .01, p<.05) compared to the unmarried in terms of compensation system and working condition , which are subfactor of duty satisfaction . In terms of the length of one's service, the longer service term one has the higher significance level one shows in compensation system, working condition, safety, and external factor which are sub-factors of duty satisfaction In terms of an academic background, one who graduated from a high school shows significance statistically only in working condition which is a subfactor of duty satisfaction compared to other people (p<0.5) The second, among sociological characteristic and internal factor of duty satisfaction, the married is more significant statistically(P<.05) compared to the unmarried in terms of achievement which is a subfactor of duty satisfaction. In terms of age the older one shows higher significance level in stability which is a subfactor of duty satisfaction compared to younker one(p<.05) In terms of the length of one's service the longer service term one has ,the higher significance level one shows(p<.01, p<.05). The third, in terms of duty stress due to sociological variable, the married is more significant statistically(p<.05) in case of stress stems from police duty than the unmarried Interms of age, welfare and duty stress are significant statistically(P<.05) Interms of the length of one's service, police's work is significant statistically(P<.05). One who graduated from junior college is significant statistically in police's work, welfare, stress and gets a lot of stress in personal relations(p<.05). The forth, groups participating in exercise are more significant statistically in stability(p<.001), feeling of stability(P<.001), achievement(p<.001), internal factor(p<.01), external factor(p<.05) than croups not Participating in exercise. The fifth, groups participating in exercise are more significant statistically only in personal management than groups not participating in. The sixth co-relation between duty satisfaction and duty stress is r=-0.3814, (P<.001) ,which shows opposite co-relation. so, a result the more stress one has, the lower duty satisfaction he gets.

rac-5.5.7.12.12.14-hexamethy1-1,4,8,11-tetraazacyclotetradecane hydrate : Lm·H_(2)O was prepared and separated from the corresponding meso-isomer dihydrate according to the Curtis method. The racisomer was confirmed by spectroscopic data of NMR and IR spectroscopy. To synthesize the [CrL_m(OH)₂] complex. the racemic compound purified from meso and racemic mixture was reacted with Cr(II1) salt. The complx ion species {[SrL_m(OH)_(2)]^(+): λ_(max) = 613.0(ε_(max) = 116 M^(-1)cm^(-1)), {[CrLm(OH)(H_(2)O)]^(2+) : λ_(max) = 575.0nm(ε_(max) = 133M^(-1)cm^(-1)). [CrLm(H_(2)O)_(2)]^(3+) : λ_(max) = 532.0nm (ε_(max) = 172M^(-1)cm^(-1))} obtained from pH change of [CrLm(OH)_(2)(OH)_(3)]^(+) solution were confirmed from an electron absorption spectra. The result of the distribution diagram of chemical species proves that main products in the range of solution pH ≤ 3.5 . 3.5 <pH <7, and pH ≥ 7. are [CrLm(H_(2)O)_(2)]^(3+). [CrL_(m)(OH) (H_(2)O)^(2+). and [CrL_m(OH)_(2), respectively. At P~ 2.0, we synthesized several Cr(III)-macrocyclic complexes containing various axial ligands (L_(a) : I, Br^(-), CI^(-), S_(2)O_(3)^(2-), F^(-), malonate, NCS^-, oxalate) instead of H_(2)O. [CrL_m(OH_(2))]^(3+) + L_(a) →[CrL_(m)(L_(a))_(n)]^(+)(n = 1 or 2) Cr(III)-macrocyclic complexes combined with vaious ligands on the axial position were primarily confirmed with the mass spectrum. Especially, when the axial ligands are malonate, oxalate, and S_(2)O_(3)^(2-), a possible thermal decomposition reaction and redox potential are considered as follows: ◁표삽입▷(본문을 참조하세요) As well, a spectrochemical series was drawn up on the basis of the ligand field strength obtained from electron absorption spertra of the complexes, [CrL_(m)(La)_(n)]^(p+) F^(-), CI^(-) ~Br^(-)<I^(-)<S_(2)O_(3)^(2-)<OH^(-)<H_(2)O<mal~NCS^(-) We can expect that there is three d-d transition d^(3) ion Tanabe-Sugano diagram. ◁표삽입▷(본문을 참조하세요) However, we found only two trasitions because the other transition {^(4)A_(2)_g(F)→^(4)T_lg(P) : v_(3)} is obscured by absorption arising from charge transfer transition. ◁표삽입▷(본문을 참조하세요)
