This study analyzes the foreign consumers' preferences and the willingness to pay for the Korean traditional dried persimmons by conducting surveys to Japanese, Americans, Canadians, Europeans, Australians, and New Zealanders. The results show that the potential export demand is largest to Japanese and those to U.S. and Europe are sufficient. The results also indicate that the price has to be reduced and the quality has to be improved in order to extend the export demand for the Korean traditional dried persimmons.

Temporal bone high resolution computed tomogram(TBHRCT)is a essential diagnostic tool in considering for cochlear implantation in patients with profound sensorineural hearing loss. This study was designed for an effort to provide and efficacy of TBHRCT in determination of inner ear malformations for the patients who have profound sensorineural hearing loss and to examine the relationships between TBHRCT findings and other preoperative evalutions for cochlear implantation in that patients. Authors examined 68 deaf patients to provide fundamental data for cochlear implantation. Inner ear abnormalities were founded in 13(19%) patients, among which 10(14.7%) patients had Mondini'dysplasia in which 5 patients were hypoplastic type and 5 patients were hydrops type. Other inner ear abnormalities were as follows : lateral semicircular canal hypoplasia ; internal auditory canal abnormality ; cochlear aqueduct widening ; vestibular aqueduct widening. No relationships were found between TBHRCT findings and other test results. : promontory test, K-WISC cognitive test etc.(Korean J Otolaryngol 39 : 8, 1996)

Freezing resistance of winter bud and xylem at each tip, middle and base portion of current year twigs of 32 chestnut cultivars was measured on October 30, December 1,1977 and January 10, 1978. The bud and xylem collected on October 10 and bud on December 1, 1977 did not show consistant difference in freezing resistance among tip, middle and base portion of the twigs. Freezing resistance of the xylem collected on December 1,1977 and January 10,1978 was in order of tip, middle and babe portions from highest to lowest in most cultivars of chestnut. The importance of lower freezing resistance of the base portion than the tip was discussed to determine cold resistant cultivars and grafting methods of chestnut.

學校組織의 葛藤과 葛藤管理

The purpose of this study is to review the theoretical background of conflict and to examine the method of management through the aspects of conflict between the educational members in schools. According to its subject, conflict is defined in many ways and it appears as psychological process when an individual and a group don't make more than two behaviors under certain circumstances simultaneously. There are two types of conflict and they occur at the same time: one is functional conflict promoting the organized functions and the other is disfunctional conflict interrupting them. To promote and minimize them is essential to conflict management. Conflict in school becomes serious in underestimating or denying the mutual role and function from individual interests to party or group interests through sympathizers. Consequently the educational reformers and the members of organization must solve the problem through the interests of group leaving out th theory of winners and losers. It is more important than any other element that the members must have strong will to solve the problem successfully.

Since the concept of clean air at hot spring resorts in Chungju city depends upon the scientific evidence of air pollution state, the atmospheric data at this city should be compared with other cities. The aim of this study was to investigate a degree of atmospheric cleanness at Chungju city comparing with other ones. The measurement results at this city showed the concentration of sulfur dioxide (S0_2; 0.0043 ppm/yr ~ 0.04 ppm/yr), total suspended particulate(TSP; 38.5 ㎍/m^3/hr ~ 90 ㎍/m^3/hr), ozone(0_3; 0.0133 ppm/hr ~ 0.0267 ppm/hr), nitrogen dioxide(N0_2; 0.0078 ppm/yr ~ 0.037 ppm/yr), and carbon monoxide(CO; 3.9 ppm/hr - 21.2 ppm/hr). The atmospheric cleanness at Chungju is involved in high group (p<0.05; high group vs low group) among the hot spring resort cities - Changwon, Seoul, Pusan, Soowon, Taejon, and Kangrung. As Chungju has a lake and less developed manufacturing area, the establishments of frontier industry, the leisure industry, the spa-medical industry and education facilities are strongly recommended for the municipal policy of the city.

This study compares the usefulness of remote sensing with that of aerial photography as a main data source for urban land analysis and development planning. The data was collected over inland districts under the administrative control of Mokpo city, but the results of the study are easily generalized. The main environmental factors considered were annual changes in vegetative ground covering, categorized into sectors according to the type of surface soil supporting it. Remote sensing techniques facilitated the collection of large amounts of data over a wide area in a relatively short time. Remote sensing data was also easy to collect repeatedly on an ongoing basis, making it useful as a fundamental data source for town planning and urban land development. On the other hand, aerial photographs offer a superior spatial perspective on urban lands, making them very useful as data for detailed planning in specific areas slated for intensive development.

This is to investigate the posibility of home manufacturing of heavy chemical industry machines, such as rotary kiln, crusher, blower, cooler, electrostatic precipitator and weighing feeder of cement plant. It is concluded that even though we can not make all of them (some of them are made now and some others are going to be made in the near future, some of them are made whole and some others are made partially), we can build or export the cement plant by importing the important machines which we can not make now and by substituting them with ours gradually.

ASOG 그룹기여법에 의한 공비혼합물의 공비점 추산에 관한 연구

趙泰煥 단국대학교 1987 論文集 Vol.21 No.-

Phase equilibrium data are very impotant and useful for designing separation process of operation, for example, vapor liquid equilibrium data for distillation and solid liquid equilibrium data for drystallization. However only limited experimental data are available for any particular conditions of temperature, pressure and composition that are required for particular design. The ASOG model is one of the useful methods to interpolate or extrapolate the existing mixture data, or when the suitable data or not available, to estimate the desired equilibrium data. By the ASOG method is based on the "solution of group" model, liquid phase activity coefficients were predicted in terms of the parameters associated with the pairs of scutrutal groups of the solution. The paramesers have been determined for 31 groups of the group dair parameters using vapor liquid equilibrium data. The existence and nonexistence of azeotropes were judged by the azeotropic formative condition. for prediction of the azeotropic point, I have chosen an abjective function F=ly_1-x_1/x_1 that have calculated by the Regular-Falsi method.

The optimal conditions for nickel-hydride secondary batteries were investigated in the ZrNi hydrogen absorbing alloys. The Zr_7Ni_10 and ZrNix(1.0≤χ≤3.0) allyos, electrochemical behaviour such as charged hydrogen contents by electrolysis, discharge characteristics and changes in the partial molar enthalpy and entropy with hydrogenation were investigated in an alkaline electrolyte. It was found that the ZrNi_x (1.0≤χ≤3.0) system alloys which consist of monoclinic ZrO_2 exhibit large discharged hydrogen capacities. Furthermore, from the values of the charged hydrogen contents and the results of the x-ray investigations.

Laves상 ZrV_2계 수소저장합금 전극의 Ni 치환에 따른 열역학적 안정성에 관한 연구

조태환,최원경 단국대학교 2000 論文集 Vol.35 No.-

Thermodynamic properties of laves phase ZrV_2 were studied in terms of the equilibrium hydrogen pressure. ZrV_2 alloy with high equilibrium hydrogen pressures at room temperature, which is usually difficult to charge, was substituted with Ni partialy. Partial substitution of Ni made not only the equilibrium pressure to be reduced remarkably, but also the enthalpy change depending on the formation of metal hydride to be agreed to the value in gas phase reaction and electrochemical reaction.
