This study was conducted to examine the physicochemical properties and hot air-dried and spray-dried powders process of sweet potato and steamed sweet potato. The moisture and the total starch contents were 1.66~2.19% and 52.65~57.42%, respectively. The total starch contents increased during process steaming. The water absorption index of the spray-dried powders (0.97 and 2.03) was lower than that of the hot air-dried powders (2.12 and 4.71), and the water solubility index of the spray-dried powders (83.83 and 86.95%) was higher than that of the hot air-dried powders (68.40 and 81.21%). The particle size and outer topology of the spray-dried powders were 46.18 and $65.53{\mu}m$, and its shape was generally globular. In the DSC analysis of this study, the $T_o$ of the spray-dried powders (64.40 and $67.80^{\circ}C$), $T_p$ of the spray-dried powders (74.40 and $78.20^{\circ}C$), and $T_c$ of the spray-dried powders (81.10 and $81.60^{\circ}C$) was higher than that of the hot air-dried powders. The solubility contents of the spray-dried powders (68.21 and 80.73%) was lower than that of the hot air-dried powders, and the swelling power contents of the spray-dried powders (14.79 and 15.35%) was higher than that of the hot air-dried powders. The amylose contents of spray-dried powders (11.67 and 12.51%) was lower than that of the hot air-dried powders. The soluble dietary fiber contents of spray-dried powders (1.34 and 2.02%) was higher than that of the hot air-dried powders.
The physiological and biochemical role of potassium for upland crops according to recent research reports and the nutritional status of potassium in Korea were reviewed. Since physical and chemical characteristics of potassium ion are different from those of sodium, potassium can not completely be replaced by sodium and replacement must be limited to minimum possible functional area. Specific roles of potassium seem to keep fine structure of biological membranes such as thylacoid membrane of chloroplast in the most efficient form and to be allosteric effector and conformation controller of various enzymes principally in carbohydrate and protein metabolism. Potassium is essential to improve the efficiency of phoro- and oxidative- phosphorylation and involve deeply in all energy required metabolisms especially synthesis of organic matter and their translocation. Potassium has many important, physiological functions such as maintenance of osmotic pressure and optimum hydration of cell colloids, consequently uptake and translocation of water resulting in higher water use efficiency and of better subcellular environment for various physiological and biochemical activities. Potassium affects uptake and translocation of mineral nutrients and quality of products. potassium itself in products may become a quality criteria due to potassium essentiality for human beings. Potassium uptake is greatly decreased by low temperature and controlled by unknown feed back mechanism of potassium in plants. Thus the luxury absorption should be reconsidered. Total potassium content of upland soil in Korea is about 3% but the exchangeable one is about 0.3 me/100g soil. All upland crops require much potassium probably due to freezing and cold weather and also due to wet damage and drought caused by uneven rainfall pattern. In barley, potassium should be high at just before freezing and just after thawing and move into grain from heading for higher yield. Use efficiency of potassium was 27% for barley and 58% in old uplands, 46% in newly opened hilly lands for soybean. Soybean plant showed potassium deficiency symptom in various fields especially in newly opened hilly lands. Potassium criteria for normal growth appear 2% $K_2O$ and 1.0 K/(Ca+Mg) (content ratio) at flower bud initiation stage for soybean. Potassium requirement in plant was high in carrot, egg plant, chinese cabbage, red pepper, raddish and tomato. Potassium content in leaves was significantly correlated with yield in chinese cabbage. Sweet potato. greatly absorbed potassium subsequently affected potassium nutrition of the following crop. In the case of potassium deficiency, root showed the greatest difference in potassium content from that of normal indicating that deficiency damages root first. Potatoes and corn showed much higher potassium content in comparison with calcium and magnesium. Forage crops from ranges showed relatively high potassium content which was significantly and positively correlated with nitrogen, phosphorus and calcium content. Percentage of orchards (apple, pear, peach, grape, and orange) insufficient in potassium ranged from 16 to 25. The leaves and soils from the good apple and pear orchards showed higher potassium content than those from the poor ones. Critical ratio of $K_2O/(CaO+MgO)$ in mulberry leaves to escape from winter death of branch tip was 0.95. In the multiple croping system, exchangeable potassium in soils after one crop was affected by the previous crops and potassium uptake seemed to be related with soil organic matter providing soil moisture and aeration. Thus, the long term and quantitative investigation of various forms of potassium including total one are needed in relation to soil, weather and croping system. Potassium uptake and efficiency may be increased by topdressing, deep placement, slow-releasing or granular fertilizer application with the consideration of rainfall pattern. In all researches for nutritional explanation including potassium of crop yield reasonable and practicable nutritional indices will most easily be obtained through multifactor analysis.
The properties, land use and genesis of the Jang-weon series, Planosol-like soils, distributed in Cheong-do area were investigated. Planosol-like soils in Korea have been believed unsuitable for perennial crops but 34.6% (594ha) of the Jang-weon soils in Cheongdo-gun are used for perennial crops such as apples, persimmons, peaches, mulberry etc. With productivity more or less equal to alluvial soils. The reason for high productivity and a working hypothesis for the genesis of the fragipan is suggested with discussion.

To follow the government policy on 'balanced development of county', the employees of public agencies to be relocated should get used to the new working and living environments such as changing their homes or living away from their family. This study aims to figure out the awareness of the employees of public agencies to be relocated on such organizational change with Person-Organization fit concept and then to find out the effect of positive or negative awareness on job attitude such as organizational commitment and turnover intention. It is expected that public service motivation, the intrinsic motivation for public employees, positively acts as a medium between the awareness of organizational change and job attitude, which this study confirms through an empirical analysis of the employees of electric power public enterprise to be relocated. This study proves that firstly the awareness on organizational change is not directly related to organizational commitment, however, it affects directly turnover intention and public service motivation as an immediate cause and secondly public service motivation has a positive correlation to organizational commitment but it doesn't affect turnover intention and lastly organizational commitment has a negative correlation to turnover intention. Besides, this study empirically finds out that public service motivation has mediating effect which is significantly affects the awareness of organizational change, organizational commitment and turnover intention, and organizational commitment has mediating effect between public service motivation and turnover intention as well.
In this study, 110 adults aged 40 to 69 years were surveyed from April 28, 2016, to May 28, 2016 to analyze their periodontal status according to daily stress, coping methods, and oral health behavior. The collected data were analyzed using the t-test, one-way analysis of variance, and hierarchical multiple regression. Daily stress levels of all subjects were most frequent potential risk 64.5% of the subjects, the high risk 19.1% and 16.4% of the health group. Regarding stress coping methods, active methods recorded 2.46, passive methods recorded 2.32. Regarding oral health behaviors, subjects brushed an average of 2.45 times daily, for an average of 2 minutes. Futhermore, 69.1% of subjects brushed before bedtime and 89.1% practiced scaling. Regarding periodontal status, the O'Leary index was 73.45, gingivitis index was 1.30, an average of 2.83 quadrants possessed a periodontal pocket. The hierarchical multiple regression analysis identified, type of employment (${\beta}=-0.348$), scaling (${\beta}=-0.253$), and age (${\beta}=0.244$) as factors that influence the number of quadrants possessing a periodontal pocket. These results confirmed that the oral health behavior of scaling, but not stress levels of coping methods, strongly influenced periodontal status.
This study was performed to examine the cytotoxic effects of nicotine on the seminiferous tubules and Leydig cells in mice testis. A different amount of nicotine (2~15 mg/kg, for two weeks, one dose of 100 mg/kg) were administered to four-month male mice, and then the optical microscopic findings of its effect on testis of the mice are as follows: 1. The group that 2 mg/kg of nicotine was administered showed normal findings that nucleus and cytoplasm of Leydig cells are distinct, while the other group that 5 mg/kg of nicotine was given to showed nucleus and cytoplasm are swollen and thickened a little, and slightly dyed. 2. The group that 10 mg/kg of nicotine was given had irregular arrangement of spermatogenesis inside seminiferous tubules so it was impossible to distinguish phages of seminiferous tubules. It was also impossible to observe cells due to fusion of their nucleuses, and distinct cytoplasm. 3. The group that 15 mg/kg of nicotine was administered showed destruction of nucleuses and cytoplasm of spermatocytes and sperms and a fill of fibered connective tissues so that it is impossible to observe rumens of seminiferous tubules.
This study reviews the concept and characteristics of the deconstruction philosophy in order to analyze the major aspects of the fashion world called the deconstruction fashion based on the deconstruction philosophy, and analyzes the works of Jean Paul Gaultier in terms of Derrida's deconstruction theory. The scope of this research is from 1980 to present, and this study fashion on the many kinds of literature on philosophy, aesthetics and literary criticism, and the domestic and international fashion journals and magazines. The deconstructionism is the philosophical theory which denies the traditionally recognized logocentric metaphysical theory and refuses the closed world and pursues the open world, opposing the dichotomic theory which is the deep-rooted tradition of the Western philosophy. The results of analyses centering on the internal deconstruction trend expressed in the works of Jean Paul Gaultier are as follows. 1 The past style combined with the present appears in the form of the entirely new trace, not the past emotion and meaning in Gaultier's works transcending the time and space. 2 Gaultier presents the unconventional intermeaning of meanings, producing various possibilities according to the wearing method of the wearer by layering several clothes. 3. Gaultier breaks from masculinity and femininity in the intertextuality of gender, and decomposes the fixed idea of men's or ladies'wear through the design sharing bisexual text. 4. In the intertextuality of T.P.O., Gaultier presents the problem of how to wear by mixing different items through obscuring the division of the nature of time, space, and purpose. Especially Gaultier can be called the first designer who, worthy of the father of the deconstructionism, has introduced in the fashion making inner wear like outer wear. 5. In the intertextuality of coordination, Gaultier presents a new perspective of coordination through free combination and contrast, raising a question about the man-made harmony criterion and deconstructing the clothes. On the other hand, Gaultier expresses the intertextuality of the material through the heterogeneous combination of the material. 6. The decomposition trend expressed in the many works of Gaultier reflects an open mind presenting a new perspective through the distortion of the form, exaggeration, and break from the existing construction method. 7. The decentering trend in the works of Gaultier is found to deconstruct the Western-dominated elements against the background of subcultural elements, the elements borrowed from the minority race, md the Oriental culture. 8. The discontinuity clothes of Gaultier present the disordered principle of design without the uniform rules, and express the unrestrained freedom without captivation by the preconceived idea through the disruption of the dress and its ornaments just like Gaultier.
To establish law-put fertilization technique and increase of fertilization efficiency during cultivation of plastic film mulching for plastic the improvement of soil properties, nutrition efficiency and yield by banded subsoil fertilization (BSF) using band spoty applicator was conducted at radish (Raphanus sativus L.) field in Honan Agricultural Research Institute from 1997 to 1998 for 2 years. These results were as follows. T-N, available $P_2O_5$ exchangeable Ca and K contents of soil were increased those of before experiment especially in BSF treatment. Also, the content of soil $NO_3-N$ was higher in BSF as fertilization amount is increasing than in CF (conventional fertilization). Uptake amounts of nitrogen fertilized were high in BSF during overall the growth period of plant and N utilization was high by $21.9{\sim}30.4%$ in BSF compared to in CF. The rate of fertilizer loss by rainfall was largely reduced, because all fertilizer applied was putted around the root zone. The total yields of fresh radish BSF treatments were more increased $13{\sim}37%$ than that of CF treatment.
Cleft palate has been studied with epidemiologic and molecular methods, and many etiologic factors have been examined closely Among the research methods, biologic molecule research has been the most important method for cleft palate formation study The $TGF-\beta$ played an important role in cell migration, epithelial-mesenchymal transdifferentiation, extracellular matrix synthesis and deposition. But there was not much research on the correlation cleft palate induced by beta-aminonitroproprionitrile(BAPN) and $TGF-\beta$ expression. The purpose of the present study was to examine how $TGF-\beta$ is expressed in cleft palate rats. 4 Timed-pregnant Sprague-Dawley rats were obtained on the 10th gestation day. On the 13th day of gestation, BAPN-monofumarate salts (${(C_3H_6N_2)}_2{\cdot}C_4H_4O_4$) were individually, ovally administered to 3 pregnant rats at a ratio of 1g/kg body weight. And 4 pregnant rats were sacrificed on day 20 post coitus (p.c.). The $TGF-\beta$ expression in the cleft formed rats fetuses showed the following patterns : 1. Osteoblast and mesenchymal cells of the cleft pa)ate rats were of low expression compared with those of the control rats. 2. The cleft palate rats didn't show uy difference in the $TGF-\beta$ expression of osteocyte item the control rats. 3. In western blot analysis, the thickness of band of $TGF-\beta$ in the cleft palate rats was thinner and more diluted than that of the control rats.
Today, every culture has taken on the compromise form by means of the cultural difference, variety, and pluralism according to the internationalization and the advance so that it has been developed toward the half-blooded and multilayered the aspect. In accordance with this current of the times, this thesis observed the feminism found in the multiculturism of the end of the 20th century, the third world, and technology with the side of the tendency of modern fashion, considered the hybride phenomenon which is pulling down the wall between culture and genre due to the social diversification. and predicted the fashion trend do 21st century serf on it. Multiculturism is the movement that began to arise in the academic world of America and the literary world form the close of 1980's in accepting the variety of culture and regarding the culture with the more balanced and wide view and just as it is, it means the attitude of accepting one or more cultures of variely and the position of taking interest in the culture of minority race not the culture of a governing race. It is the fashion of feminism adapts dualism like unisex, androgynous look, etc of bisexual lendency in the 1980's, it shows new style with crossover of liberal sense because there is not the difference of sex in fashion. The eco-feminism pursues the natural sexuality not being instrumental and dismantling and expressed it in the Gender expression of an integrated human being. The trend of ethnic fashion in the close of 20th century is that the element of hippie is working so strongly. By adding embroidery of Oriental style, accessories of Indian style, feathers, beads, a hempen hood to the ethnic costumes of Asia and Latin, is shows the figure of ethnic hippie. As the cycler fashion is the future clothes through technology of computer, it uses a cool glass material bringing up the image of a spacesuit in order to expresses cyber image through artificial color combination of sheen colors, Though this techno-color fashion has established the fresh stimulation and the innovative aspect with ultramodern materials and image of futurism, it transmits a hope of estranged people and the natural elements. Hybride means a cross and mixture of animal and plant in Korean and is also called fusion. The phenomenon of hybrid predicts to comes the period of a cross and variation because something completely new comes into the world by contamination, mixture and compromise through meeting something different each other and it has on advantage of developing something existing to one more stage. It is prospected that in the society of 21st century, the borderline of traditional gender will be disappeared, variety and individuality will determine the individual behavior, and the masculine value will be substituted by feminine value. In the society giving priority to feminine value, a fashion stuck closely to women is what must reflect lives of woman under the proposition of woman's beauty, being on original function. So, it is considered that a fashion with added convenience and practicality having the function which is easy to put on, comfortable to act, able to express solves so much, and able to show various appearances according to T.P.O will get into the spotlight.
