Oral melanin pigmentation is common in some races and ethnic groups. The gingivae are the most frequently pigmented intra-oral tissues. Melanin pigmentation is the result of melanin granules, produced by melanoblasts intertwined between epithelial cells at the basal layer of the epithelium. We present one case of melanin pigmentation of the gingiva of 26-year old female. Melanin depigmentation method is applying a 90% phenol solution to deepithelize pigmented areas, gingivectomy, epithelial abrasion, bone denudation, and split thickess flap. We chose epithelial abrasion using round diamond bur. The patient satisfies the result and have almost no pain and discomfort. But repigmentation potential must be noticed to patient.

The South Asian Association for Regional Cooperation (SAARC) nations are a potpourri of diverse religions, races and cultures with rich natural and cultural heritage but yet to tap the full potential of tourism. An investigation into the glorifying heritage of these eight SAARC nations pinpoints towards their rich food and culinary heritage that is yet to be explored to carve them as food destinations that would definitely help ameliorating tourism too. The Global Report on Food Tourism of the United Nations World Tourism Organization (UNWTO) reveals results from a survey on food tourism marketing promotion, from which internet marketing tools, such as websites have been effectively utilized to promote food tourism in a particular destination. (UNWTO, 2012). Sensing the importance of the websites in the promotion of food tourism for any destination, the present study aims at the comparative content analysis of the official tourism websites of SAARC nations to evaluate their performance from the perspective of promotion of culinary heritage on world -wide web. The modified Balanced ScoreCard (BSC) approach is incorporated into the evaluation by taking into consideration four perspectives: technical, user friendliness and site attractiveness, tourism effectiveness and food tourism effectiveness. A set of 88 critical success factors representing these four perspectives is then used to examine the websites. The study reflects on the relative strength and weakness of the tourism websites of SAARC nations in promoting food tourism and as well help suggesting the remedial measures catalyzing the food tourism promotion through websites.

Worldwide, rice blast, caused by Magnaporthe grisea (Hebert) Barr. (anamorph, Pyricularia grisea Sacc.), is one of the most economically devastating crop diseases. Management of rice blast through the breeding of blast-resistant varieties has had only limited xuccess due to the frequent breakdown of resistance under field conditions (Bonman etal., 1992; Correa-Victoria and Zeigler, 1991; Kiyosawa, 1982). The frequent variation of race in pathogen populations has been proposed as the principal mechanism involved in the loss of resistance (Ou, 1980). Although it is generally accepted that race change in M. grisea occurs in nature, the degree of its variability has been a controversial subject. A number of studies have reported the appearance of new races at extremely high rates (Giatgong and Frederiksen, 1968; Ou and Ayad, 1968; Ou et al., 1970; Ou et al., 1971). Various potential mechanisms, including heterokaryosis (Suzuki, 1965), parasexual recombination (Genovesi and Magill, 1976), and aneuploidy (Kameswar Row et al., 1985; Ou, 1980), have been proposed to explain frequent race changes. In contrast, other studies have shown that although race change could occur, its frequency was much lower than that predicted by earlier studies (Bonman et al., 1987; Latterell and Rossi, 1986; Marchetti et al., 1976). Although questions about the frequency of race changes in M. grisea remain unanswered, the application of molecular genetic tools to study the fungus, ranging from its genes controlling host specificity to its population sturctures and dynamics, have begun to provide new insights into the potential mechanisms underlying race variation. In this review we aim to provide an overview on (a) the molecular basis of host specificity of M. grisea, (b) the population structure and dynamics of rice pathogens, and (c) the nature and mechanisms of genetic changes underpinning virulence variation in M. grisea.

This study is to reconsider the symbolic potential of the costume by investigating the role of cloth in Indian culture, noting the fact that Indians wore hand-woven cloth and adopted a flag with the spinning wheel in the center as part of their nationalistic programs for independence. The results are as follows; The Indian cotton industry had held the fist position in the world and spinning and weaving had been an Indian national industry until the early part of the 19th century. As for the Indian cotton industry under the rule of Britain, Indian was reduced to being a colony producing raw materials and a market of cheap British finished goods, and eventually fell into anarchy with economic poverty of the general public and peasants'uprising mixed with the complaint of the intellectuals. The Indian National Movement started as a resort to escape the British rule because of continuous poverty and social exhaustion, and its pivot was Gandhi. Gandhi launched a revolutionary noncooperation movement in Indian society with diverse races, religions and castes, and developed nation-wide campaigns such as Boycott, Swadeshi, the encouragement of spinning wheels, etc. Gandhi urged that Indians' weak identity and poverty were caused by the dissolution of their native craft and that the Indians should wear Indian products for economic independence. Accordingly, leaders of Indian National Congress regarded a spinning wheel as an economic necessity and national symbol, and approved manual spinning and weaving as part of their nationalistic programs in order to drew the general public to the nationalistic movement in 1920. They also decided that all Congressmen should wear hand-woven cloth, Khadi, and adopted spinning wheels as the logo type of Indian National Congress. Khadi, Indian national cloth, was a symbol of national unification, freedom and equality, and also a means of economic self-sufficiency, Swadeshi, and eventually led India to autonomy, Swaraji. Therefore, it can be concluded that the cloth converted Indias economic and political identity.

Objective : The purpose of this study was to evaluate the influence of a community based group exercise intervention on motor functional capacity. To evaluate the immediate(post-treatment) effects after 6-weeks exercise program on the group exercise intervention(PNF and Circuit exercise). Methods : Subjects-Included persons with stroke who were living in the community. Thirty-seven subjects were randomly assigned to the PNF, Circuit exercise and control group participated in a repeated measures design that evaluated the subjects with pre-treatment, post-treatment(6 weeks). Functional ability outcome measures assessed the motor assessment scale(MAS) and EMG. Both treatment groups participated in exercise cJass three times a week for 6 weeks. Group programs focused on balance, functional motor capacity and walking ability. The PNF program was modified PNF pattem and techniques with emphasis on functional tasks when possible, as well as stretching of the more affected limb particularly in the more affected shoulder. The Circuit program with subjects completing practice at a selies of work station as well as participating in walking races and relay with other members of the group. Results : Compared with the control group, the treatment group had larger improvements in the motor function ability after 6 weeks treatment and Post-treatment test scores were more significant than the pre-treatment score. 1. Motor function were assessed by using MAS, sit to stand, walking and upper function were assessed pre-treatment versus post-treatment measures revealed a statically significant(p<.05). There were significant differences between the groups. Compared with the control group, the treatment group had larger improvements. 2. In the treatment groups, demonstrated difference in the electromyographic activation of biceps, triceps, quadriceps and tibialis anterior muscles on the paretic side in the response to the reaching arm movement and stepping motion in stance. The difference in muscle activation improvement were not statically significant. Conclusion : The results of this study showed that the PNF and Circuit group exercise intervention can improve motor functional ability. This study suggests that the PNF and Circuit exercise programs is appropriate for community-based group exercise principles. It leads to gain and maintain potential function for disabled persons after stroke in the community.

As the nature of triathlons is competition in three successive sports, triathletes experience elevated levels of stress on the body that are absent in single-sport athletic events, and consequently there are more potential medical problems to prepare for. Triathletes can also experience problems such as hypothermia, heat illness, excessive exposure to ultraviolet radiation, musculoskeletal injuries and trauma, immunosuppression, and haemolysis. Depending on the potentiality of such above-listed problems occurring in any given race, race organizers will prepare preventative measures and treatments accordingly. Olympic distance is not the only triathlon racing distance. Sprints, which are normally around half the Olympic distance, are common distances, as well as Long (2 km swim, 80 km bike, 20 km run), Ironman (3.8 km swim, 180 km bike, 42 km run), and ultra-distance events varying in length. Races of longer duration normally result in a higher percentage of athletes experiencing the above-mentioned medical problems, as well as inducing additional health risks such as hyponatraemia. Minimizing the occurrences of serious health issues is possible through the following means: carefully preparing for the probable race-day weather conditions; proper management and organization of the race; preparing an extensive water-safety and ground-course safety plan; distributing necessary nutrition along the course; and stressing the importance for athletes to have proper knowledge concerning race nutrition, biomechanical technique, physical preparation, and utilization of safe equipment. While risks of competing in triathlon are many, the instances of such medical problems are not excessive, and the triathlon has a reputation of being a reasonably safe sport as long as athletes with high risk take added precautions.

A computer program written to predict blast occurrence based on micro climatic events was developed and tested as an on-site microcomputer in field plots in 1984 and 1985. A microcomputer unit operating on alkaline batteries; continuously monitored air temperature, leaf wetness, and relative humidity; interpreted the microclimate information in relation to rice blast development and displayed daily values (0-8) of blast units of severity (BUS). Cumulative daily BUS values (CBUS) were highly correlated with blast development on the two susceptible cultivars, M-201 and Brazos grown in field plots. When CBUS values were used to predict the logit of disease proportions, the average coefficients of determination $(R^2)$ between these two factors were 71 to $91\%$, depending on cultivar and year. This was a significant improvement when compared to 61 to $79\%$ when days were used as a predictor of logit disease severity. The ability of CBUS to predict logit disease severity was slightly less with Brazos than M-201. This is significant inasmuch as Brazos showed field resistance at mid-sea­son. The results in this study indicate that the model has the potential for future use and that the model could be improved by incorporating other variables associated with host plants and pathogen races in addition to the key environmental variables.

The number of emigrants along with globalization and internationalization is rapidly increasing. The international migration is creating a new form of acculturation and a new structure of society. Racial or cultural diversity resulting from political, economical, and cultural exchange is drastically increasing. This study aimed to provide policy plans or basic data to improve multicultural acceptability in the future. Accordingly, it was also to set and verify causal effect of multicultural acceptability. For those purposes, a questionnaire was made up based on the literature about acculturation, and a survey was taken in korean. The results are as follows. Dependant variables used in analysis were sub-factors of multicultural acceptability founding three types called 'The Actual Acceptance', 'The Active Acceptance', 'The Passive Acceptance'. It was found that positive effect in multicultural acceptability through media experience was an important factor to reduce discriminant of multicultural community members. Therefore, we need to produce diverse media programs that can improve multicultural acceptability and reduce negative perception of multicultural community members. Additionally, multiculture education to help understanding of other races and other cultures should be developed as subject courses in university.
