Objectives : In this study I made investigations how 'strange hunger' and 'compulsive overeating' threatening the ego could be resolved and healed. And I aim to present a healing model of psychotherapy and analysis as one of methods of treatment for 'eating disorder'. Methods : The analysands of this study were outpatients who visited the department of psychiatry of Yong-In Mental Hospital from March 2008 to February 2017 with 'hunger' and 'compulsive overeating' as their chief complaints. This study is based on the detailed records of the process of analysis including dreams and visions. Results : 1) Throughout the process of analysis that explore both consciousness and unconsciousness(dream, vision), hunger and compulsive overeating is improved and healed in all analysands. 2) The Imago of 'Snake' appeared in dreams and visions of all analysands. 3) By suffering impulse rather than acting it out, impulse transformes itself into 'Imago'. As impulse transforms into 'Imago' and reveals the 'meaning' of it, ego-threatening power of impulse weakens and mood is calmed. And as a result, synthesis of consciousness and unconsciousness and creative transformation of personality can be possible. Conclusions : In some people, 'hunger' and 'compulsive overeating' are 'creative impulses' that aim 'Self-realization' which can be fruited as creative transformation of personality and as creative transformation in the relation with the world. 'Creative impulses', which often can be experienced as instinctive impulse or emotional suffering unless ego realizes the meaning, reveal the meaning in dreams or visions through 'Imago' and 'Symbol'.

Coal ash can be added to agricultural soils to increase the chemical properties of soil such as pH, cation exchange capacity and nutrient availability of - B, Ca, Mo etc-. Therefore, the main purpose of this study was to evaluate the feasibility of fly ash as a soil amendment in paddy soils. Selected fly ash was mixed with bentonite and calcium hydroxide at the ratio of 80:15:5 (w/w) and manufactured as a pellet type at the size of 10 mm. Field experiments were conducted to evaluate the effects of fly ash fertilizer on the soil quality and crop growth compare to the control (no fertilizer) and, - traditional fertilizer. Results showed that soil pH and organic matter in paddy soils after applying the manufactured fly ash fertilizer were not increased compared to the other two treatments. However, the concentration of available phosphate and silicate in paddy soils were higher than those of the control and traditional fertilization. With regard to crop growth, no significant difference was observed between three different treatments. However, the content of protein in the rice grain cultivated with the fly ash fertilizer was higher than in the rice cultivated by other two treatments. Overall, fly ash fertilizer could increase the concentration of available silicate and phosphate in the paddy soil and improve the rice quality. In conclusion, fly ash can be utilized in agricultural soils as soil amendment, especially in the rice paddy soil.

Effects of mushroom powder on physicochemical characteristics of dough and bread-making properties were studied. In mixogram test, addition of 2-10% mushroom powder increased water absorption from 67,0 to 79%. Peak time, peak height, band width, and seven minute height of mushroom-wheat flour composite were similar to those of control. Sedimentation and P.K. values decreased with increasing amount of mushroom powder In amylogram test, no significant difference was observed in gelatinization temperature between control and mushroom powder-added dough. Peak viscosity increased with increasing amount of mushroom powder, Highest loaf volume was attained when 2 and 4% mushroom powders were added, whereas decreased above 6%. Bread weight and L value of crust increased with increasing amount of mushroom powder whereas 'a' value decreased. As the amount of mushroom powder increased, L value of crumb color decreased. No significant difference in springiness and adhesiveness was observed between control and mushroom-wheat composite flour bread whereas chewiness and gumminess, increased with increasing amount of mushroom powder, Hardness generally increased as the amount of mushroom powder increased. Mushroom powder caused bread staling at both storage temperatures ($4^{\circ}C\;and\;25^{\circ}C$). Although sensory value decreased with increasing mushroom powder, use of mushroom powder to replace up to 4% wheat flour is recommended in making bread.

In this study, engineering grade and high intensity reflective sheets were prepared with glass beads and their reflection performance and physical properties were investigated. The reflective sheets prepared by using glass beads are divided into enclosed or encapsulated lens type, depending on whether the glass beads are open in air or not. Because of an extra layer on the glass bead surface, the enclosed lens type reflective sheets show very little change in the properties by bad weather conditions, compared to encapsulated lens type reflective sheets. Optimization of the amount of glass beads on the surface was carried out, which determines the retroreflective properties. Enclosed and encapsulated lens type reflective sheets with various colors were prepared and their coefficients of retroreflection were determined. The encapsulated type reflective sheet with white color shows a coefficient of retroreflection of $210.4cd/1x{\cdot}m^2$, which is higher than the enclosed type ($74cd/1x{\cdot}m^2$). Effect of washing on the reflective property and adhesive power of the reflective sheets was investigated, and it is found that the number of glass beads decreased with washing and the aluminum layer deposited was damaged extensively in the encapsulated lens type reflective sheets.

The purpose of this study was to analyze the effect on the selectivity on of high-voltage rectification device that measured the performance of the grid, and the contrast improvement ability (K factor) by measuring the scattered radiation content of the transmitted X-rays. The scattered radiation generated when the X-ray flux comes from the diagnostic X-ray generator that passes through an object. Targeting four different rectifications of X-ray generators, the mean value of the tube voltage and the tube current was measured in order to maximize the accuracy of the generating power dose within the same exposure condition. Using fluorescence meter, the content of the scattered rays that are transmitted through the acrylic was measured depending on the grid usage. When grid is not used, the content of the scattered rays was the lowest (34.158%) with the single-phase rectifier, was increased with the inverter rectifier (37.043%) and the three-phase 24-peak rectification method (37.447%). The difference of the scattered radiation content of each device was significant from the lowest 0.404% to the highest 3.289% while using 8:1 grid, the content of the scattered ray was the lowest with the single content of the scattered ray was the lowest with the single-phase rectifier (18.258%), was increased with the rectifier (25.502%) and the 24-peaks rectification (24.217%). Furthermore, there was difference up to content 7.244% to the lowest content 1.285% within three-phase 24-peaks rectification, inverter rectifications, and single-phase rectifier depending on the selectivity of the grid. Drawn from the statistical analysis, there was a similar relationship between the contrast improvement factor and the K factor. As a result, the grid selectivity and the contrast were increased within the single-phase rectifier rather than the constant voltage rectifier.

In this study, the antioxidant effect of water and ethanol extracts from Juniperus rigida Sieb were investigated. The activities of each of the extracts were measured based on their total phenolic and flavonoid contents and using antioxidant test such as of 2,2-azinobis (3-ethyl benzothiazoline-6-sulfonic acid (ABTs) radical scavenging activities, ferric reducing antioxidant power (FRAP), angiotensin I converting enzyme (ACE) inhibition activity, antioxidant protection fator (PF), thiobarbituric acid reactive substances (TBARs) content, and ${\alpha}$-glucosidase and ${\alpha}$-amylase inhibition activity assay. The result of the examination to measure the polyphenol content by investigating the antioxidativity of the J. rigida Sieb. extract showed 71.3 mg/g polyphenol content in the water extract, and 116.0 mg/g in the ethanol extract and a 17.7 mg/g flavonoid content in the water extract and in 76.4 mg/g in the ethanol extract. The ABTS radical cation decolorization showed 76.4% and 79.3% scavenging activities of the $500{\mu}g/mL$ water extract and ethanol extract, respectively. The FRAP showed 1.83 mM efficacy in the water extract and a lower 1.77 mM in ethanol extract. Both the water extract and the ethanol extract showed reduced ACE activities of 75.39% and 71.25% at $500{\mu}g/mL$, respectively. The antioxidant protection factor of the water and 70% ethanol extracts of J. rigida Sieb were 1.5 PF and 2.1 PF, respectively. In the TBARS inhibitory activity, the extracts showed 55.78% and 71.48% antioxidant activities at the $500{\mu}g/mL$ concentration. The results of the measurrement of the ${\alpha}$-amylase inhibitory activity indicated more than 90% of activity inhibition in the $500{\mu}g/mL$ concentration of the ethanol extract. For the ${\alpha}$-glucosidase inhibitory activity, the ethanol extract showed 70% activity inhibition at the $500{\mu}g/mL$ concentration.

The number of the disabled person had been increased for the industrial accident and the environmental pollution. Especially, developmental disability has the high prevalence rate between 5% and 10% of the whole children. The children with a developmental disability can be treated by the physical therapy, the occupational therapy, the psychology therapy, speech therapy, and art therapy. Visual preception which is function to recognize the external environment through the optic organ could be related to most behaviors on the everyday life. But because the children with disability could not develop the visual-preception enough, they came to have difficulties in executing daily life project. For this reason, it is most important to understand the estimation and the cure on the visual-preception in the pediatric occupational therapy. To improve the visual-preception power, we have many kind of methods including sensory integration, training program for the visual-perception and art-craft program. Particularly, the art-craft which is the representative activity for making something by hands, can be applied to anyone. As the study on the brain has been activated, it was proved that handicraft actives could have an good effect on the brain function and using brain. When the fine motor exercise and more delicate and accurate motion were carried, these motions need the essential help of the visual-perception. So it could be expected that using the repetitive hand function by art-craft makes the brain function improve, when a activity that needs a fine motor exercise and more delicate, accurate motion was carried, It also indicates that the art-craft program has a clear treatment value. Though the intervention between visual-perception development and visual-perception disability have a majority in the field of occupational therapy, there is a few study yet. Therefore, this study tried to look back on the necessity of applying the art-craft program to the children with disability as the prestudy for preliminary validity of the master's thesis.

Against the backdrop of the increasing trend towards economic globalisation, many international firms are indicating that decisions on how to enter foreign markets remains one of the key strategic challenges confronting them. Despite the rich body of literature on the topic, the fact that these challenges have continued to dominate global marketing strategy discourses point to someevident lacunae. Accordingly, this paper considers the variables, categorised in terms of firm contexts (standardisation, market research, competition, structure, competitive advantage) and host country-contexts (economic development, cultural differences, regulation and political risk), which influence the degree of involvement of UK companies in overseas markets. Following hypotheses were drawn from literature review: H1: The greater the level of competition, the higher the degree of involvement in the overseas market. H2: The more centralised the firm's organisation structure, the higher the degree of involvement in the overseas market. H3a: The adoption of a low cost-approach to competitive advantage will lead to a higher degree of involvement. H3b: The adoption of an innovation-approach to competitive advantage will lead to a higher degree of involvement. H3c: The adoption of a market research approach to competitive advantages will lead to a higher degree of involvement. H3d: The adoption of a breadth of strategic target-approach to competitive advantage will lead to a lower degree of involvement. H4: The higher the degree of standardisation of the international marketing mix the higher the degree of involvement. H5: The greater the degree of economic development in the host market, the higher the degree of involvement. H6: The greater the cultural differences between home and host countries, the lower the degree of involvement. H7: The greater the difference in regulations between the home country and the host country, the lower the degree of involvement. H8: The higher the political risk in the host country, the lower the degree of involvement. A questionnaire instrument was constructed using, wherever possible, validated measures of the concepts to serve the aims of this study. Following two sets of mailings, 112 usable completed questionnaires were returned. Correlation analysis and multiple regression analysis were used to analyze data. Statistically, the paper suggests that factors relating to the level of competition, competitive advantages and economic development are strong in influencing foreign market involvements. On the other hand, unexpectedly, cultural factors (especially individualism/collectivism and low and high power distance dimensions) proved to have weak moderating effects. The reason for this, in part, is due to the pervading forces of globalisation and the attendant effect on global marketing. This paper has contributed to the general literature in a way that point to two mainimplications. First, with respect to research on national systems, the study may hold out some important lessons especially for developing nations. Most of these nations are known to be actively seeking to understand what it takes to attract foreign direct investment, expand domestic market and move their economies from the margin to the mainstream global economy. Second, it should be realised that competitive conditions remain in constant flux (even in mature industries and mature economies). This implies that a range of home country factors may be as important as host country factors in explaining firms' strategic moves and the degree of foreign market involvement. Further research can consider the impact of the home country environment on foreign market involvement decisions. Such an investigation will potentially provide further perspectives not only on the influence of national origin but also how home country effects are confounded with industry effects.

Statement of problem: Recently precalcification treatment has been studied to shorten the period of the implant. Purpose: This study was performed to evaluate the effect of precalcification treatment of $TiO_2$ Nanotube formed on Ti-6Al-4V Alloy. Material and methods: Specimens of $20{\times}10{\times}2\;mm$ in dimensions were polished sequentially from #220 to #1000 SiC paper, ultrasonically washed with acetone and distilled water for 5 min, and dried in an oven at $50^{\circ}C$ for 24 hours. The nanotubular layer was processed by electrochemical anodic oxidation in electrolytes containing 0.5 M $Na_2SO_4$ and 1.0 wt% NaF. Anodization was carried out using a regulated DC power supply (Kwangduck FA, Korea) at a potential of 20 V and current density of $30\;㎃/cm_2$ for 2 hours. Specimens were heat-treated at $600^{\circ}C$ for 2 hours to crystallize the amorphous $TiO_2$ nanotubes, and precalcified by soaking in $Na_2HPO_4$ solution for 24 hours and then in saturated $Ca(OH)_2$ solution for 5 hours. To evaluate the bioactivity of the precalcified $TiO_2$ nanotube layer, hydroxyapatite formation was investigated in a Hanks' balanced salts solution with pH 7.4 at $36.5^{\circ}C$ for 2 weeks. Results: Vertically oriented amorphous $TiO_2$ nanotubes of diameters 48.0 - 65.0 ㎚ were fabricated by anodizing treatment at 20 V for 2 hours in an 0.5 M $Na_2SO_4$ and 1.0 NaF solution. $TiO_2$ nanotubes were composed with strong anatase peak with presence of rutile peak after heat treatment at $600^{\circ}C$. The surface reactivity of $TiO_2$ nanotubes in SBF solution was enhanced by precalcification treatment in 0.5 M $Na_2HPO_4$ solution for 24 hours and then in saturated $Ca(OH)_2$ solution for 5 hours. The immersion in Hank's solution for 2 weeks showed that the intensity of $TiO_2$ rutile peak increased but the surface reactivity decreased by heat treatment at $600^{\circ}C$. Conclusion: This study shows that the precalcified treatment of $TiO_2$ Nanotube formed on Ti-6Al-4V Alloy enhances the surface reactivity.
