The purpose of this study is to investigate the effects of closed and open kinetic chain exercise for increasing knee joint function on the knee position sense in the normal adults. Thirty normal adults(male 15, female 15; mean age: 22.13±2.58 years) were participated in this study into two groups, each with 15 people. The group I was trained that closed kinetic chain exercise on the knee joint and the group II was trained that open kinetic chain exercise on the knee joint. Exercise programs performed for 4 weeks, 3 times a week were using Shuttle 2000-1 closed kinetic chain exercise and Knee Extensor open kinetic chain exercise(HUR, Filand). The results of this study were as follows: 1) There were statistically significant decreasing of measuring error degree in 0-20。were found between before and after training in closed kinetic chain exercise(p<.05). 2) There were statistically significant decreasing of measuring error degree in 21-40。were found between before and after training in closed kinetic chain exercise(p<.05). 3) There were statistically significant decreasing of measuring error degree in 41-60。were found between before and after training in closed kinetic chain exercise(p<.05). 4) There were statistically significant decreasing of measuring error degree in 0- 20。were found between before and after training in open kinetic chain exercise(p<.05). 5) There were statistically significant decreasing of measuring error degree in 21-40。were found between before and after training in open kinetic chain exercise(p<.05). 6) There were statistically significant decreasing of measuring error degree in 41- 60。were found between before and after training in open kinetic chain exercise(p<.05). In conclusion, these results suggest that closed and open kinetic chain exercise has increased in the knee joint proprioception between before and after training. Especially, closed kinetic chain exercise could be more useful intervention than open kinetic chain exercise for increasing proprioceptive sense.

The majority of strokes are caused by ischemia and result in brain tissue damage, leading to problems of the central nervous system including hemiparesis, dysfunction of language and consciousness, and dysfunction of perception. The purpose of this study was to investigate the effects of Poly(ADP-ribose) polymerase(PARP) on necrosis in neuronal cells that have undergone needle electrode electrical stimulation(NEES) prior to induction of ischemia. Ischemia was induced in male SD rats(body weight 300g) by occlusion of the common carotid artery for 5 min, after which the blood was reperfused. After induction of brain ischemia, NEES was applied to Zusanli(ST 36), at 12, 24 and 48 hours. Protein expression was investigated using immuno-reactive cells, which react to PARP antibodies in cerebral nerve cells, and Western blotting. The results were as follows: In the cerebral cortex, the number of PARP reactive cells after 24 hours significantly decreased(p<.05) in the NEES group compared to the GI group. PARP expression after 24 hours significantly decreased(p<.05) in the NEES group compared to the GI group. As a result, NEES showed the greatest effect on necrosis- related PARP immuno-reactive cells 24 hours after ischemia, indicating necrosis inhibition, blocking of neural cell death, and protection of neural cells. Based on the results of this study, NEES can be an effective method of treating dysfunction and improving function of neuronal cells in brain damage caused by ischemia.

The purpose of this study examines women in 20s∼30s who start applying adult makeup and are sensitive to cosmetics and makeup techniques to understand the influence of overseas cosmetic brands’ personality on their preference to provide overseas cosmetic brands with unique personality marketing resources. The following summarize the findings of this study: first, overseas cosmetic brands’ personality factors were aesthetics, performance, interest, competency, and boldness. Second, among imported brands, the most preferred brand was Christian Dior, followed by Bobbi Brown, Chanel, SK-Ⅱ, and Estee Lauder. Third, the subjects preferred Chanel when they perceived its aesthetics, performance, and competency and Christian Dior when they perceived its aesthetics and performance and did not perceive its boldness as much. They preferred Estee Lauder when they perceived its aesthetics and competency and Bobbi Brown when they perceived its aesthetics, performance, and competency and did not perceive its boldness as much. In case of SK-Ⅱ, they preferred it when they perceived its aesthetics, performance, interest, and competency.

The purposes of this study were to provide information on customers for cosmetic companies to develop goods and promotion strategy by examining facial images of university women and their recognition level about cosmetics brand personality. The results were as follows; First, satisfaction level of university women with their lips and eyes was very high, while lowest in skins. Second, factors of brand personality of three kinds of foreign cosmetics brands and three kinds of domestic brands were sincerity, beauty, renovation, reliability and ruggedness. In beauty, reliability and ruggedness, they preferred foreign brands to domestic ones, while they preferred domestic ones in sincerity and renovation. Third, the satisfaction level with face had a statistically significant relationship to the importance of face and cosmetic brands, while the importance of face had to the beauty of the brand. In the interrelationship among facial images and the factors of brand personality, they had significant interrelationships, provided beauty and ruggedness, and reliability and ruggedness had no significant interrelationship.

Physicochemical qualities and consumer acceptability of chocolate layer cake were studied with varied levels of rosemary powder at 0, 0.2, 0.4 and 0.6%. The ash content of the cake increased from 2.30 to 3.10%, as the amount of rosemary powder increased from 0 to 0.6%, and the carbohydrate content of the cake decreased as the addition of rosemary powder increased. There were no significant differences in moisture contents and pH values among the samples and the pH values of all samples were within the typical pH range of 7.5-8.0 for chocolate， layer cakes. Water loss from the control cake was greater than that from the cakes with rosemary powder supporting the suggestion that the addition of rosemary powder to the chocolate layer cake could increase moisture retention of the cake. Consumer acceptability of all the samples showed higher prefierences of more than 7 points. Rosemary aroma, mint flavor and after taste were highly positively corrεlated with the fat content. Fat and ash content of the cake, which tended to increase in proportion to the rosemary powder content， were negatively correlated with acceptance of herb flavor, sweet taste, moistness， softness and intensity of softness but positivεly correlated with intensity of herb flavor. With the results above, trials on chocolate layer cake using rosemary powder were successfully performed within the ranges tested.

As pulp calcification occurs at least fifty percent of total teeth, the focal calcification in pulp chamber usually appears in all age groups. However, the pulp calcification is one of the important pathologic changes affecting the pulp vitality. In order to elucidate the mechanism of pulp calcification during the retrogressive degeneration of pulp tissue we performed an immunohistochemical study for proteases (MMP-3, MMP-10, and cathepsin-G), antiproteases (TIMP-1, α1- AT) and proteins involving tissue protection (TGase-2 and HSP-70). In the normal pulp tissue MMP-3 and MMP-10 were weakly expressed, but cathepsin-G and TIMP-1 were rarely expressed. Around the calcifying tissue of MMP-3, MMP- 10, and α1-AT were predominant, but TIMP-1 and cathepsin-G were sparsely expressed. On the other hands, TGase-2 and HSP-70 were condensed in the proximal fibrous tissue. These data suggest that the pulp calcification is related to retrogressive pulp degeneration, which could be resulted in the incomplete digestion of the degenerated stromal tissue by different proteases. We presume that the aberrant protease digestion of chronic pulpal pathosis, i.e., sclerotic fibrosis, chronic pulp degeneration, etc., may enhance the dystrophic calcification in dental pulp.

This study analyzed the status of climate-change indicator plants native to the main islands of the Korean peninsula, while elucidating their distribution characteristics. Information on flora from over 129 island locations, comprising more than 100 species of native plants, was collected, compiled into a database, and utilized as raw data. The distribution of 193 climate-change indicator plants was confirmed. The distribution area of broadleaf evergreen trees and ferns, including Mallotus japonicus and Cyrtomium falcatum, was relatively wide. In contrast, the distribution of common northern plants such as Corydalis turtschaninovii and Malus baccata was limited. If global warming persists, northern plant distribution is expected to decrease rapidly in the Korean Peninsula island region, while the northern limit line of the southern plants is expected to migrate further northward. During this process, it is likely that the plant congregation structure and species diversity within the island region will change dynamically. In this study, comparative analyses between species and regions were conducted by assessing the relative frequency of their occurrence, and six types of botanical geographic distribution patterns were noted.

Background: Gastrodia elata Blume is a saprophytic perennial plant in the Orchidaceae family, because of its agricultural and medicinal effectiveness, researchers focus on its genome and chemical components. However, cytogenetic information based on the chromosome structure and composition to construct chromosomal backbone for genome sequencing research and for the development and breeding of plants is very limited. Methods and Results: We determined the metaphase chromosome composition of the G. elata genome by fluorescence in situ hybridization (FISH) using 5S and 45S rDNAs and telomeric repeat probes. The nuclear genome of G. elata was organized into 2 n = 36, with relatively small (2.71 - 5.50㎛)chromosomes that showed gradual decrease in size. Conglutination phenomenon was observed among the metaphase chromosomes, and it was distinguished from that in other plant metaphase chromosome spreads. One pair of signal was detected for each 5S and 45S rDNA in the pericentromeric region and interstitial region on the short arm of chromosomes 10 and 4, respectively, and telomeric DNA signals were detected in the terminal region of most chromosomes. Conclusions: To our knowledge, this is the first FISH chromosome composition result in G. elata and could be useful in more comprehensive molecular cytogenetic and genomic analyses as well as breeding programs of the medicinal plant G. elata.

Platycodon grandiflorum (Bell flower) is an important plant that has traditionally been used as herbal medicine for the treatment of cough, phlegm, sore throats, lung abscesses, chest pains, dysuria, and dysentery. The present study was initiated to investigate the feasibility of inducing shoot and root organogenesis in cultured explants of P. grandiflorum in a range of culture media and through use of various plant growth regulators (PGRs). The plantlets (Stem containing one node) were isolated and cultured on different concentrations of Murashige and Skoog (MS) medium supplemented with PGRs. We found that proliferation and elongation of shoots and roots could be achieved on ¼ MS for P. grandiflorum with wild and green petals and on ⅛ MS for P. grandiflorum with double petals. The highest levels of development and elongation of adventitious shoots and roots were observed when petal explants were cultured on ¼ MS (pH 3.8) supplemented with 5% sucrose. Increasing the agar concentration reduced shoot growth and rooting potential; nevertheless, the highest number of shoots and roots was observed on 0.6% agar. In the case of growth regulators, ¼ MS supplemented with 1 mg L-1 6-benzylaminopurine (BA) was found to be best for shooting, although higher concentrations of BA tended to reduce shoot and root elongation. The highest number of shoots was achieved on 0.5 mg ․ L-1 thidiazuron (TDZ) from double petal explants grown on ⅛ MS. However, root and shoot elongation were found to decrease when TDZ concentrations were increased. Low concentrations of kinetin, naphthalene acetic acid, indole acetic acid, and 3-indole butyric acid induced shoot and root proliferation and elongation. Taken together, our study showed that low concentrations of PGRs induced the greatest root formation and elongation, showing that the optimal concentration of PGRs for shoot proliferation was species-dependent.

Background : In order to develop new cultivar of hybrid kiwifruit with cold tolerance, high useful components and high quality fruit, we have been crossed ‘Hayward’ (Actinidia deliciosa) with A. arguta. The new hybrid kiwifruit cultivars were 'DM', 'HO', and 'JW'. Actinidia arguta, called hardy kiwifruit, has an edible smooth skin and contains high amounts of sugar and vitamin C. It is native to north China, Korea, and Japan. A. deliciosa are known as kiwifruit and originated in Southwest China. The fruit of A. deliciosa appreciated for its sweet, slightly acidic flesh and high nutritional value, especially due its high content in vitamin C like A. arguta. The cultivar ‘Hayward’ of A. deliciosa occupies the majority of the world kiwifruit cultivated surface, and is the cultivar commercially produced in Korea. However, the kiwifruit producing areas are limited to warm climates region, it can be cultivated in the southern parts of Korea. In our research, several hybrids have been developed to enhance cold tolerance by crossing ‘Hayward’ with domestic species. Methods and Results : In our research, several hybrids have been developed to enhance cold tolerance by crossing ‘Hayward’ with domestic species. Freeze dried the fruit of hybrid kiwifruit was finely ground, extracted twice with methanol (MeOH). The crude extracts of the fruit was analyzed with HPLC for vitamin C and β-carotene analysis. Conclusion : Moisture and carbohydrate contents of hardy kiwi fruit in this study varied from 81.40 - 83.57% and 14.63 - 16.90 g/100 g, respectively. Among new cultivars, JW had higher fat(0.17 g/100 g) and protein(1.33 g/100 g) contents than others. The highest vitamin C and β-carotene content of hardy kiwi fruit were 120.70 ㎎/ 100 g, 0.14 ㎎/kg, respectively in DM.

Background : Despite the presence of various bioactive compounds in ginseng, there is lack of study on the variations of bioactive compounds in ginseng according to the cultivation of soil and the applied fertilizer types (or amount). Therefore, this study aims to examine the variations of 37 fatty acids (FA) and 8 vitamin E (Vit-E) vitamers in 6-year-old ginseng root cultivated in different soil types with different fertilizers regimes. Methods and Results : The profiling of 37 FAs and 8 Vit-E vitamers in 6-year-old ginseng roots was measured by gas chromatography coupled with a flame ionization detector, and then these results were statistically analyzed with chemometrics. The FA and Vit-E content in ginseng roots varied significantly with respect to soil cultivation conditions due to organic fertilizer types and amounts used. Unsaturated FA in ginseng is approximately 2.7 fold higher than the saturated FA. Linoleic, palmitic, and oleic acids were the most abundant FAs found in the ginseng roots. Also, the major Vit-E vitamer found in ginseng root is α -tocopherol. In particular, the application of rice straw compost or food waste fertilizer was increased to create nutritionally-desirable FAs and bioactive Vit-E in ginseng root. In addition, phytonutrient profiling coupled with chemometrics can be used to discriminate the cultivation conditions of ginseng. Conclusion : This preliminary study extends our understanding about the variations of FA and Vit-E in ginseng root depending on cultivation conditions. Hence, these results can be useful as basic information for reliable ginseng production containing high amounts of phytonutrients in a paddy-converted field.

In the genus Chrysanthemum, repetitive DNA sequences, the dominant part of a genome, are still to be elucidated. To explore the matter, the present study applied fluorescent in situ hybridization (FISH) to the mitotic metaphase chromosome of Chrysanthemum boreale with C0t DNA as probes. Based on DNA re-assotiation kinetics, three kinds of C0t DNA exhibiting different degrees of repetitive nature were fractionated and used as FISH probes to map the repetitive sequences. Signals from all C0t DNAs were successfully observed but their coverage on the chromosomes was different among C0t-1, C0t-10, and C0t-100. C0t-1 FISH signals resulted to have its intensity on the telomeric region and were also dispersed on both chromosome arms except for some distal regions. In C0t-10, signals were observed in all parts of the chromosome with greater intensity around pericentromeric regions. FISH with C0t-100 DNA was observed in bright signals all over the chromosome. Signals of C0t FISH found in this study covered the regions where ribosomal DNAs and telomeric repeats of C. boreale have been distributed (previous report), thus signifying their repetitive attributes. The present results could enhance the efficiency of studying genomes, chromosomes and repetitive sequences of C. boreale and subsequently hasten the realization of the genetic scheme of Chrysanthemum.

This study was performed to investigate the growth characteristics and inorganic components of Codonopsis lanceolata regarding regional differences. The plant height of Japanese Codonopsis lanceolata was 373.6 cm, so it’s revealed that it has more vigorous growth than Korean won. The flowering time of Korean Codonopsis lanceolata was 2 weeks faster than Japanese one. Total fresh weight of root was 41.0 g and 39.0 g for Korean and Japanese respectively, thus, no significance difference was found. However, regarding fresh weight, Korean one had a more fresh weight (35.4 g) of main root parts, but Japanese one had a more fresh weight (9.6 g) of the lateral root part. Each inorganic component was found more in the aboveground parts, regardless of the region and the content of K was the largest. Regarding the content of macroelements for each part of Codonopsis lanceolata, the content of Na, Mg, P, S, and Ca in Korean Codonopsis lanceolata was found the highest on the leaf, followed by stem and root. In the case of Japanese Codonopsis lanceolata, same result was found on the content of Mg and Ca, however, the highest content of Na and P was found in the stem.
