1. 본 연구는 중국 산동성의 평도시(平度市) 및 신강성 집단재배농장을 대상으로 주요 채소 농산물인 고추, 마늘, 양파에대하여 한국과 중국의 생산 관리체계 및 기술 수준을 비교ㆍ분석하였다. 2. 고추의 경우 한국은 묘를 구입하여 정식하는 비율이 높지만 중국은 대부분 자가 채종 후 자가 육묘를 하는 체계이다. 가장 특징적인 것은 한국은 수확을 10일 간격으로 5 ~ 6회 하지만, 중국은 일시 수확하여 수확노동력을 줄이고 있다. 고추의 경영비와 생산비 비교에서는 각각 한국이 3,975원/kg,11,686원/kg이며, 중국은 519원/kg, 1,895원/kg으로 한국의 경영비가 7.3배, 생산비는 6.2배 차이가 나는 것으로 조사되었다. 3. 중국의 마늘 파종량은 한국에 비해 3배 이상으로 밀식파종을 한다. 재배 이랑은 한국은 넓은 이랑이며, 중국은 2줄 좁은 이랑에서 재배 하고 있다. 멀칭은 한국이 기계멀칭을 64%하고 있으나 중국은 인력을 이용한 멀칭을 하고 있다 마늘의 경영비와 생산비 비교에서는 각각 한국이 1,128원/kg, 2,049원 /kg이며, 중국은 310원/kg, 686원/kg으로 경영비는 3.6배, 생산비는 3.0배 차이가 나는 것으로 분석되었다. 4. 양파는 중국이 한국보다 경지기반은 좋으나 호당 경지면 적은 0.14 ha로 매우 영세하다. 한국은 복비와 유기질 비료를 사용하고 방제를 3 ~ 5회하는 반면, 중국은 계분을 사용하고, 살균, 살충, 제초 방제는 1회만 실시하고 있다. 육묘는 중국과 한국이 모두 구입종자를 이용한 자가 육묘를 하는 동일한 생산체계이다. 양파의 경영비와 생산비 비교에서는 각각 한국이 199원/kg,334원/kg이며, 중국은 46원/kg, 98원/kg으로 한국보다 경영비는 4.3배, 생산비는 3.4배 차이가 있은 것으로 나타났다. This study was carried out to analyze the Chinese vegetable production system and to compare it with the adopted system in Korea. Farm producing pepper, garlic and onion in Sandong and Singang were surveyed. For pepper production, Korea farm purchased the planting materials while, China farm produced their own seeds and seedlings. Also, the most significant difference was the one time harvesting in China, while Korea usually harvests 5 ~ 6 times within 10 days term per year with an increase in production. The management and production cost were observed to be 3,975 won/kg, 11,686 won/kg for Korean pepper, but China has low cost by 519 won/kg, 1,895 won/kg. An amount of garlic seed in China was more than three times that of Korea. Korea covered the wide furrow with mulching plastic and used machines that raised the production rate by 64%. However, Chinese depends on the human labor and make narrow furrow to increase the productivity. The management and production cost were 1,128 won/kg, 2,049 won/kg for Korean garlic, while China has low cost by 310 won/kg, 686 won/kg respectively. To cultivate onion, the land condition of China was better than Korea having an average farm size of 0.14 ha smaller than Korea. Two nations were compared having the same seedling production system that buy the seed at the market and seedling their own land. Likewise, the management and production cost observed as 199 won/kg, 334 won/kg for Korean onion, while Chinese cost was lower by 46 won/kg, 98 won/kg. It is concluded that the good producing system of China such as pepper one-time harvesting system should be adopted to korean farm system to reduce cost.

Bioequivalence of two cilostazol tablets, the Pletaal^(R)(Korea Otsuka Pharmaceutical Co., Ltd.) and the Cilozol^(R)(Hanmi Pharmaceutical Co., Ltd.), was evaluated according to the guideline of KFDA, Sixteen normal male volunteers(age 20~29 years old) were divided into two groups and a randomized 22 cross-over study was employed. After two tablets containing 50㎎ of cilostazol were orally administered. blood was taken at predetermined time intervals and the concentration of cilostazol in plasma was determined with an HPLC method using UV detector. The pharmacokinetic parameters(C_(max), T_(max) and AUC_(t)) were calculated and ANOVA was utilized for the statistical analysis of parameters. The results showed that the differences in C_(max), T_(max) and AUC_(t) between two tablets were 4.99%, 1.74% and 7.68%, respectively. The powers(1-β) for C_(max), T_(max) and AUC_(t) were83.92%, 80.12% and 85.03%, respectively. Detectable differences(Δ) and confidence intervals were all less than 20%, and confidence interval of all the parameters were also less than 20% at the significance level(α) of 0.05. All of these parameters met the criteria of KFDA for bioequivalence, indicating that Cilozol^(R) tablet is bioequivalent to Pletaal^(R) tablet.

최종하 안동대학교 기초과학연구소 1990 基礎科學 硏究論文集 Vol.1 No.1

It is shown that the photolabilized ligand on the substitution reactions of trans-[RhL_(4)XY]^(n+) is predicted by considering a total stabilization energy of several square pyramidal intermediates resulting from the loss of one ligand. The energy levels of total stabilization and d-orbital for the intermediate are calculated within the framework of the angular overlap model. According to the calculated results, the intermediates with larger total stabilization energy are, as expected, more easily produced. Consequently, the relative values of total stabilization energy are used to determine which the ligand in trans-[RhL_(4)XY]^(n+) complexes is preferentially labilized on the lowest energy d-d irradiation. The prediction for the substituted ligand on the photochemical reaction of trans-[RhL_(4)XY]^(n+) complexes is consistent with the experimental results.

Teratomas are embryonal neoplasms that show characteristics of three germ cell layers(ectoderm, mesoderm, and endoderm). They are distributed in the following regions: sacrococcygeal(57%), gonadal(29%), mediastinal(7%), cervical(3%), retroperitoneal(4%), and intracranial(3%) regions. Non-gonadal treatomas present in infancy whereas gonadal are seen in adolescence. Especially, teratomas that occurred in midline neck of adult are very rare and are confused with thyroglossal duct cysts, cystic hygromas, and thyroid tumors. We report, along with the review of appropriate literature, a case of histopathologically confirmed benign teratoma in the midline neck of a 33 years old woman.

The electronic d-d spectra of trans-[Cr(cyctn)X₂]^(+) (cyctn=l,5,9,13-tetraazacyclohexadecane; X=F, Cl) complexes have been interpreted in terms of the ligand field theory. The band maxima are fitted with secular determinant for quartet state energy of d^(3) configuration in tetragonal field including configurational but neglecting spin-orbit coupling. A spectral fitting computer program is used to minimize the differences between the calculated and the observed positions for the spin-allowed transition bands. The crystal field parameters are directly related to the normalized spherical harmonic hamiltonians, angular overlap and semiempirical parameters. Values of the various ligand field parameters have been obtained and discussed from the point of view their chemical significances. The results derived from the analysis of the electronic spectra allow us to determine the energy levels of d-orbital and quartet state of trans-[Cr(cyctn)X₂]+ complexes. According to the results of ligand field analysis, it is confirmed that the fluoride ligand is a very strong σ- and π-donor while the chloride has weak σ- and π-donor properties toward chromium(III) ion

전이금속 착물의 전자구조 및 화학적 반응성(제7보). : Rex법에 의한 [M(H₂O)_(6)]^(2+)착물의 분자궤도함수론적 연구 A Molecular Orbital Study of the [M(H₂O)_(6)]^(2+)Complexes by the Relativistic Extended Hu¨ckel Method

최종하 安東大學 1990 安東大學 論文集 Vol.12 No.1

The relativistic extended Hulckel (REX) calculations of [M(H2O)6]2+ complexes (where M=Ti, V, Cr, Mn, Fe, Co, Ni, Cu) have been carried out in order to investigate the electronic structure and relative stability. Trends in the calculated orbital population and atomic charge agree with experimental results. Satisfactory agreement is also obtained with experiment data and with earlier assignments both for the energy levels and for their relativistic splittings. It is found that the increase in stability of the complexes from titanium to copper, together with a decrease in the susceptibility to oxidation can be rationalized by correlating the drop in total energy.

The purpose of this paper is to study retrofit methods for improving the flexural capacity of RC shear wall. Four RC shear wall specimens are designed and strengthened by using reinforcement or steel plate. Cyclic loads are applied to the specimen under constant axial force. Test result shows that the strength and ductility of specimen is improved when it is strengthened using reinforcement or steel plate. The specimen retrofitted by using steel plate shows high ductility. However the strength contribution of one is not much. It is shown that the most effective method is both to install the additional flexural reinforcement and to confine the ends of wall.
