The auther embedded the clinically differently used direct resins to the oral submucosa of the rabbits, and compared the tissue reactions to the direct resins with that to the indirect resins. The results were as follows: 1. Direct resins showed more lympocytes infiltration than indirect resins at the early stage of the embedding, but the same degree of the appearance of lympocytes infiltration as indirect resin at the late stage of the embedding. And the formation of fibrosis around the embedding showed the irregular finidng. 2. Fibrosis of direct resin showed the tendency to be finer than indirect resin at the early stage of the embedding, but direct resin formed the similar fibers capsule to that of indirect resin at the late stage of the embedding.

The main purpose of this study was to examine the relations between Children's peer victimization, self-esteem, and loneliness with a sample of 494 elementary school students (293 boys and 231 girls) living in Pusan. Data was analyzed by correlations and regressions. Children's direct/indirect peer victimization were positively related to loneliness. Expecially, indirect peer victimization was more positively related to loneness than direct peer victimization was. Children's self-esteem was negatively related to loneliness. Children's direct/indirect peer victimization were negatively related to self-esteem. Expecially, direct peer victimization was more negatively related to self-esteem than indirect peer victimization was. In boys, self-esteem tended to play a perfectly mediating role between indirect peer victimization and loneliness. In girls, self-esteem tended to play a partially mediating role between direct peer victimization and loneliness.

The National Health Insurance Act, the Industrial Health Act and the School Health Act require chest radiography at least once a year. In chest radiographic examination, most group examinations use indirect X-ray primarily aiming at diagnosing diseases and enhancing people's health. This study purposed to minimize radiation exposure dose by comparing it between direct and indirect chest X-ray studies. According to the result of comparing and analyzing radiation exposure dose, the average incident dose and penetrating dose were 0.929μGy and 0.179μGy respectively in direct chest X-ray and 6.807μGy and 1.337μGy in indirect chest X-ray In order to minimize radiation exposure dose at direct and indirect chest X-ray, indirect X-ray should be excluded from group examination if possible. Moreover, it is necessary to control the quality of equipment (Q/A & Q/C) systematically and to avoid using unqualified equipment in order to reduce radiation exposure dose.

For the purpose of evaluating the effect of both direct retainer design and bony absorption degree around abutment of indirect retainer on the supporting tissue of abutment of indirect retainer, dislodging force was transmitted to unilateral distal extension RPD bases. Analysis of stress distributed within the supporting tissue around abutment of indirect retainer was carried out. Using three-dimensional photoelastic stress analysis method and the conclusion is a follows. 1. According to the extent of force which the direct retainer of the most distal abutment tooth, the amount of force transmitted to the abutment tooth of indirect retainer was small. 2. Of all the cases, Mandibular first premolar which was used abutment tooth of indirect retainer, buccal, mesial and distal sides represented compression stress and lingual side represented tensile stress. 3. The more bone resorption of abutment tooth of indirect retainer, the more distortion of buccal and distal side of abutment tooth was existed and the extent of compression stress which was existed and distal side to abutment tooth was large. 4. When the alveolar bone around the abutment with indircet retainer is normal. The amount of force transmitted on abutment with indirect retainer was small in the order of Akers clasp, RPA clasp, RPI clasp. 5. When the alveolar bone around the abutment with indirect retainer has been absorbed 20% and 30%, the amount of force transmitted on abutment with indirect retainer was small in the order of RPA calsp, RPI clasp, Akers clasp. 6. When denture is displaced, shape of the direct retainer reciprocating abutment affect much the function of indirect retainer.

The purpose of this study was to compare direct and three indirect blood pressure measurements in adults and to compare among three indirect blood pressure measurements in adults. One direct(intraarterial) and three indirect(using a mecury sphygmomanometer, a aneroid type sphygmomanometer and an automatic auscultatory device) methods of blood pressure measurement were compared in adult patients who had an arterial line. The subjects for this study consisted of 29 patients in K medical center, B medical center, B hospital and M hospital in Pusan. The data was collected from October 1, 1992 to June 30, 1993. The collected data was analysed with the SPSS program, frequency, percentage, mean, S.D., t-test, ANOVA. The results of this study were as follows : 1) There was a significant difference in the systolic BP when using the direct and three indirect measurements(P<0.05). 2) There was no overall significant difference in the diastolic BP when using the direct and three indirect measurements. 3) There was no significant difference in the SBP and DBP among the three indirect measurements.

The paper aims to investigate the impact of presenting statements of cash flow using the direct method and the indirect method on loan decision by credit officers at Vietnamese banks. The data was collected from 150 credit officers of commercial banks in Vietnam based on the questionnaire about making loan decision when the cash flow statement is presented in different methods, namely, direct and indirect methods. This research uses T-tests to check whether using the direct or indirect method affects the accurate calculation of loan criteria, affects the loan decision by credit officers, and compare these two methods in the aspects of information provision. The research has pointed out that: 1) the direct method helps the calculation of indicators related to loans more accurately; 2) credit officers say that, while the direct method of presenting cash flow statement provides clearer information, the use of either the direct method or the indirect method does not affect the banks' loan decision. Since then, the author recommends that cash flow statements should be provided with information in a direct method to present the information needed for loan decision more accurately so as to improve the quality of cash flow statement.

Since 1995 the Korean Ministry of Science and Technology has introduced and implemented a project based system (PBS) for awarding R&D funds. While capital investments for national laboratories such as buildings and research facilities are supported by the government, normal operating expenses including personnel expenses should be earned by national laboratories through open competition under PBS. The project budget includes both direct research costs and indirect costs. The purpose of this paper is to examine the components of indirect costs and to examine determinants of indirect costs of national laboratories in Korea. The indirect costs of nineteen national laboratories are examined. The direct personnel costs and indirect personnel costs out of total personnel costs are 72% and 28%, respectively. The average indirect cost rate is 74.1% of direct personnel costs. Major components of indirect costs are general operating costs, indirect personnel costs, taxes and dues, and expenses related to the usage of equipment. The significant determinants of indirect cost are indirect personnel ratio. the ratio of unique projects, the type of national laboratories (pure research laboratories or other), and asset activity ratio measured as research divided by total assets. The high indirect personnel ratio, the high ratio of unique projects, the laboratories classified as other, the low asset activity ratio are related to high indirect cost rates.

A preliminary study has been done to investigate the thermal performance of an indirect system. Direct systems are also analyzed and the results are compared with those of the indirect system where possible. Values from the numerical simulation show very good agreement with the measured data. Although the indirect system is generally expensive and not as efficient as direct systems, it is more reliable in frigid weather conditions like the winters in Korea.

The regional centrality plays a very important role in national and regional planning and it is measured by data such as people, goods, and information flows among regions. The inter-regional flows are usually considered by only direct flows, yet indirect flows, which are generated accordingly from direct flows, are not critically considered. Most centrality studies have also hardly reflected the indirect flow in the network analysis. This study demonstrates the significance of the indirect flows to enhance accuracy of the regional centrality. The nationwide dataset of inter-regional commuter traffic matrix is used in this study and analysed into two groups; one to consider only direct flow and the other both direct and indirect flows. The results indicate remarkable differences of centrality raking between two groups such as Yeongam of Jeonnam Province(+60th), Eumseong of Chungbuk Province(+57th), Gwacheon of Gyeonggi Province (-35th), and Nowon of Seoul (-32nd). It clearly shows the significant influence of indirect flow for regional centrality study. This also reveals regional centrality ranking in Korea by considering direct and indirect flows of commuters. Jung, Gangnam, and Jongno of Seoul are categorized in the highest rank group and Ulleung of Gyeongbuk, Ongjin of Incheon, and Jindo of Jeonnam are in the lowest group. The top group includes seven districts of Seoul, two of Busan, and one of Gyeonggi Province. The bottom group includes mostly island and costal areas. As this study shows an accurate method of centrality measurement, it has a significant implication to lead an effective regional planning.

Greenhouse gas (GHG) and Air Pollution (AP) emission inventories have been constructed and estimated independently up-to-date in Seoul. It causes difficulty in GHG and AP integrated management due to a difference in emission inventories. In this study, we constructed GHG and AP integrated emission inventories for direct and indirect sources in Seoul during the year 2010 in Energy activities for estimating GHG and AP emissions were derived from IPCC guideline, guidelines for local government greenhouse inventories, air pollutants calculation manual, and Indirect Emission Factors (IEF) reported by Korea Power Exchange. The annual GHG emission was estimated as 50,530,566 $tonCO_{2eq}$, of which 54.8% resulted from direct sources and the remaining 45.2% from indirect sources. Among direct sources, transportation sector emitted the largest GHG, accounting for 47.3% of the total emission from direct sources. As with indirect sources, purchased electricity sector only emitted 98.6% of the total emission from indirect sources. The annual AP emission was estimated as 283,701 tonAP, of which 85.9% was contributed by the combined AP emissions of transportation and fugitive sectors. Estimation of individual air pollutant showed that the largest source were transportation sector for CO, $NO_x$, TSP, $PM_{10}$ and NH3, non-energy sector for $SO_x$, and fugitive sector for VOCs. This study found some limitations in estimating GHG and AP integrated emissions, such as nonconforming emission inventories between GHG and AP, and no indirect AP emission factor of purchased electricity, and so on. Those should be further studied and improved for more effective GHG and AP integrated management.
