This study intended to activate public education, researched and analyzed real conditions of preschool education to know desirable directions of public education and help parents recognize public education. The final purpose is to offer basic materials to reestablish preschool education in the public education system. First, parents' recognition concerning preschool education in the public education system was much different from that of teachers. As for definitions of preschool education as a public education, parents understood that it means 'the nation and self-governing bodies manage aid both the public and private kindergartens', and teachers recognized that it means that 'the nation and self-governing bodies not only found operate public kindergartens but also aid manage educational funds of private kindergartens. Second, the examination of educational environments of kindergartens told that teachers and parents thought that opportunity to enter the kindergarten is not equal for all children in our country, and quality of kindergarten teachers is satisfactory. Also, they thought that curriculums of preschool educational organs have been set well according to children's developmental stages, education quality is different according to preschool education organs' foundation-types. They recognized that facilities and apparatus of preschools are satisfactory, security and neatness of preschools are satisfactory, too. Third, the examination of developmental directions of preschool education as a public education proved following facts; as for foundation-types of kindergartens in the future when promoting preschool education as a public education, parents answered financial support and supervision by the government, teachers answered aid and management of operational fees as well as support for teacher personnel expenses.
This study was performed to obtain a basic materials for improvement of garlic storage ability. The "Namhae jaerae" of southern strain and the "Dalsung jaerae" of northern strain were harvested by period, their stems were cut at 7cm and 25cm from disk and then placed them in blast drying system 12 hours per day at $40^{\circ}C$ for 4 days, or in natural state. The decrease rate of bulb weight was compared and rooting, sprouting, the rate of decay was investigated between natural dry(conventional method) and hot-air dry (blast drying system). The results obtained were as follows. In the case of the decrease rate of bulb weight after hot-air dry; 7cm plot" "Namhae jaerae" was similiar to one of 13th day of natural dry and 25cm plot 14th day. In "Dalsung jaerae" 7cm plot of early, common and late harvest was respectively similiar to one of 22nd, 18th and 16th day of natural dry, 25cm plot of early, common and late harvest showed the same decrease rate of bulb weight as that of 18th, 16th and 14th day of natural dry respectively. In the case of rooting and sprouting in sand culture at the early period of storage, hot-air dry showed more prolonged tendency than conventional drying method. In the case of clove state in the latter period of storage, number of eatable cloves was more numerous and number of decayed cloves were less in blast drying system than in conventional method.
This study was conducted to obtain basic information on the rice anther culture. Materials used were (Inabawase X YR 2404-14-2-1) $F_1$ hybrid. Callus growth rate on various media, induction frequency of callus in spikelet and panicle, and the effect of treatment on anther and callus were evaluated. The results obtained were summarized as follows ; The growth rate of callus on N-6, M-S, P.E.agar media was 19.8, 13.1, 4.1 times respectively after 30 days inoculated, and on liquid media was 3.8, 5.1, 1.4 times, respectively. Organ differentiation on N-6, M-S, P.E.agar media was 37.5%, 12.5%, 17.5% respectively. The difference of induction frequency of callus per panicle was 0.14%-6.25% and per spikelet was 0-19.05%. Almost callus was induced 30-35 days after inoculation. Organ differentiation of induced callus was decreased by culture. Callus cultured for 13 days after induction did not make shoot. Anthers cold shocked at $8^{\circ}C$ for 5 days obtained 3.32% efficiencys of callus induction per number of anthers plated, and compared with 2.41% of no treated anthers. But anther treated at $8^{\circ}C$ for 7 days decreased 2.24%. Callus induction periods were shortened by cold treatment for about 5 days. Callus cultured on medium containing 2 mg/l of 2, 4-D showed 5% on root formation but medium containing 5 mg/l of 2, 4-D showed 30% of root formation after transfered on the medium without 2, 4-D. Callus cold shocked at $15-18^{\circ}C$ revealed poor efficiency for root formation, but 5 days treatment was good for shoot formation.
This study was performed to provide basic data for predicting the usefulness of Gastrodiae rhizoma as a materials for functional foods. Changes in regional cerebral blood flow(rCBF) and blood pressure(BP) were measured in rats, following the intravenous injection of processed Gastrodiae rhizoma water extract. In its processing, we used rice water, Sderotium Poriae Cocos and Radix Ligustici Chuanxiaong. The rCBF and BP measurements were continually monitored by a laser-doppler flowmeter and a pressure transducer in the anesthetized adult Sprague-Dawley rats for approximately about two to two and a half hours, through a data acquisition system composed of a MacLab and Macintosh computer. The results of the experiment are as follows: the processed Gastrodiae rhizoma significantly increased changes in rCBF in the rats. The rCBF with processed Gastrodiae rhizoma did not change by pretreatment with propranolol, atropin, methylene blue, and indomethacin. But the rCBF of the processed Gastrodiae rhizoma was increased by pretreatment with L-NNA. The processed Gastrodiae rhizoma significantly decreased the changes in BP. However, BP with the processed Gastrodiae rhizoma did not change by pretreatment with propranolol, atropin, methylene blue and indomethacin. On the other hand, BP decreased with the processed Gastrodiae rhizoma pretreatment with L-NNA. These results indicate that processed Gastrodiae rhizoma might increase the rCBF and the BP which are related to nitric oxide synthesis. Also these results indicate that the used of processed Gastrodiae rhizoma in safe, as well as clinically applicable in diet therapy for cerebral related disease and hypertension.

Securing the radiological safety is a prerequisite for the safe management of the naturally occurring radioactive materials (NORM) which cannot be reused. This becomes a crucial focus of our R&D efforts upon the implementation of the Act on Protective Action Guidelines against Radiation in the Natural Environment. To secure the safety, the establishment of technical bases and procedures for securing radiological safety related to the disposal of NORM is required. Thus, it is necessary to analyze the characteristics, to collect the data, to have the radiological safety assessment methodologies and tools, to investigate disposal methods and facilities, and to study the effects of the input data on the safety for the NORM wastes. Here, we assess the environmental impact of the NORM waste disposal with respect to the major domestic and foreign NORM characteristics. The data associated with major industries are collected/analyzed and the status of disposal facilities and methodologies relevant to the NORM wastes is investigated. We also suggest the conceptual design concept of a landfill disposal facility and the management plan with respect to the major NORM wastes characteristics. The radionuclide pathways are identified for the atmospheric transport and leachate release and the environmental impact assessment methodology for the NORM waste disposal is established using a relevant code. The assessment and analysis on the exposure doses and excessive cancer risks for the NORM waste disposal are performed using the characteristics of the representative domestic NORM wastes including flying ash, phosphor gypsum, and redmud. The results show that the exposure dose and the excessive cancer risks are very low to consider any radiation effects. This study will contribute to development in the areas of the regulatory technology for securing radiological safety relevant to NORM waste disposal and to the implementation technology for the Act.
Trust and understanding relationship promoted between a therapist and a client is the basic building block to successful recovery. Its importance is not only pertaining to the music therapy but also to counseling and psychological therapy. Because of its gnificance, broad spectrum of research has been conducted for quite a long time. Historically, researches have been focused on therapists or client's chological variables rather than emotional effects on each other that occur during the therapy session. Recently researchers turned their attention to emotional relationship between a therapist and a client. With recent advances in the field of music and psychological therapy, subsequent study has been conducted to investigate the role that music plays in the therapeutic relationship. For this research, eleven music therapy sessions were conducted for the adult females who are alcoholics. The first three sessions were of group therapy. Fourth to eleventh therapy session was done individually. Throughout the research case-by-case study has been conducted on the basis of the analysis of video and audio taped materials. Analysis depends heavily on its reference from the Amir's music research of 1990, which used Ferrara's seven phases of phenomenological study. Especially, verbal and nonverbal communications were closely analyzed in musical perspective. Research revealed that music and musical instruments act as a mediator between a therapist and a client. By doing so, it protects a therapist from unnecessary negative emotional displacements of a client and creates mutual reliability between a therapist and a client. Here, research suggests that music and musical instrument play a central role in building relationship between a therapist and a client, and it indicates that it has positive effect on treatment.
As customers pay more attention to choosing food that will support their health, many people in the academic and industrial world have focused on developing foods made with bioactive components. Thus, the use of bioactive components rather than synthetic materials has increased. Because there are no limits to how bioactive components can be used, customers assume they are highly reliable and healthy to consume. In the present study, imitation crab stick samples were made from Alaska Pollack with breast recovered protein from spent laying hens and silkworm cocoon powder (10 g) (T1), Alaska Pollack with breast recovered protein from spent laying hens and silkworm cocoon powder (5 g) + cordyceps powder (5 g) (T2), and Alaska Pollack with breast recovered protein from spent laying hens and cordyceps powder (5 g) + conjugated linoleic acid (CLA) (5 g) (T3). The pH and shear force increased after 2 weeks of storage in all three samples. Shear force was significantly higher in the T3 sample in comparison to the T1 and T2 samples. In meat color, redness ($a^{\ast}$) and whiteness (W) increased as the storage periods increased in all three samples, whereas yellowness ($b^{\ast}$) decreased during storage. The T2 sample was significantly higher in redness ($a^{\ast}$), yellowness ($b^{\ast}$), and deformation than the other two samples. The addition of bioactive components did not influence the texture properties in any of the samples. Lipid oxidation (thiobarbituric acid reactive substances [TBARS]) and microorganism count (total plate count [TPC]) were significantly higher in the T1 sample than the two other samples, whereas protein degradation (volatile basic nitrogen [VBN]) was higher in the T2 sample than the other samples. Total amino acid content decreased in the T1 and T3 samples as the storage period increased. Consequently, the T3 sample of Alaska Pollack with breast recovered protein from spent laying hens and cordyceps powder (5 g) + conjugated linoleic acid (CLA) was found to have the necessary functionality to be considered for use in making imitation crab sticks.
A land resources survey in the semi-arid area, Mula in S. E. Spain, of $400km^2$ is compiled. The basic aim of the project is to investigate the intrinsic qualities of the land resources of the area by means of applying an integrated method of natural resources survey mainly concerning with analysis and synthesis of land complexes, each of them represents an area or a group of areas with similar patterns of landforms, soils and vegetation, based on a geomorphological approach. The area is characterized by a linear arrangement of relief pattern with an asymmetric homoclinal repetition of slope attitudes elongating WSW-ENE, dipping steeply on the NW sides and gently on the SE sides, which have been resulted from the post-Alpine folding of the Triassic to Cretaceous limestone, the Eocene limestone, the Oligocene sandstone and the lower Miocene limestone and marl, and the post-lower Miocene faulting, tilting and subsequent differential erosion of the Miocene sedimentary formations. An integrated body of information in geology, landforms, soils and vegetation, which are significantry interrelated as an environmental complex, has been obtained. Using this data, 26 land complexes developing on the various situations of landforms, such as folded mountain ranges, tilted tablelands, bevelled cuestas, degraded hill-lands associating with enormous foots lopes, undulating terrains and terraced or flat plains, have been differentiated, mapped and described. The soils of the area are mostly light colored calcic lithosols which have been derived dominantly from the marly parent materials and developed into remarkable slope catenas in some places depending on the relief conditions. The land uses of the area are mainly characterized by the perennially irrigated cultivation of citrus orchards along the terraced alluvial deposits fringing the Segura and Mula River, and the dry-land cereal cultivation on gentler slopes. Pioneer dry-land cultivations within the shrubs on steeper slopes are restricted to the unchannelled tributary drainage floors. The availability of water is a fundamental controlling factor for existence of native and cultivated vegetation as a whole, and a number of active processes including sheet wash and gully erosion, especially on the scarp slopes, are the other important factors to be considered in conservation and management of the land in the area.
Under the "Positive List System (PLS)," a uniform limit of 0.01 mg/kg is applied if the agricultural product does not have a Maximum Residue Limit (MRL) for a pesticide. The purpose of this research is to conduct residual pesticide monitoring on tropical fruits distributed in Gyeonggi-do to investigate the effects of PLS and provide basic materials for establishing MRLs of residual pesticides for tropical fruits produced in Korea. By inspecting 120 tropical fruits distributed in Gyeonggi-do according to Multi-class pesticide multi-residue methods, we detected sevenfruits from threekinds of banana, mangoes, and kiwis with six different residual pesticides. Azoxystrobin and chlorpyrifos were detected from bananas, chlorfenapyr from mangoes, and chlorothalonil, iprodione, and procymidone from kiwis. A single case of chlorfenapyr and chlorothalonil was found with a mango and a kiwi produced in Korea, respectively, and by applying PLS we found that they exceeded the MRL of residual pesticide. Thus, it is necessary to set the MRL of residual pesticides for tropical fruits produced in Korea.
