  • Background: Oral cancer stands among the 10 top causes of cancer death in the world. Considering the role of epidemiologic information on planning and effective interventions, the present study aimed to investigate the epidemiology of oral cancer in Iran. Materials and Methods: The required information for this systematic review study was obtained from PubMed, Google Scholar, CINAHL,SID, Medlib, Magiran and Iranmedex databases, using key words "cancer", "oral cancer", "squamous cell carcinoma", "oral cavity carcinoma" and their Persian equivalents in combination with keywords of epidemiology, prevalence, etiology, frequency, and Iran from 1990 to 2014. From 1,065 related studies found, finally 25 were included to the study. Results: The mean age of 8,248 patients in 25 studies was $54.0{\pm}15.1years$. The male/female ratio for oral cancer was 1.91. Tongue with average percentage of 29.9 was the most involved site. Regarding microscopic grade, 65.7% of cases were grade 1. SCCs, accounting for an average of 70.0%, was the most common among all types of oral cancer. In the majority of studies, smoking including cigarette, hookah, and tobacco consumption was found to be a risk factor. Conclusions: The epidemiological pattern of oral cancer in Iran is somewhat similar to that of other countries. Yet the information on hand in this field is limited and considering the role of epidemiological data we suggest conducting more accurate studies to catch data that is required for effective programs and interventions.

  • Background: Atrophic epithelium of cervix sampled from postmenopausal women may mimic high-grade cervical intraepithelial neoplasia in Papanicolaou-stained (Pap) smears. Ki-67 (MIB-1) protein presents on proliferating cells, and percentage of cells with positive nuclei provides a reliable tool for rapid evaluation of the growth fraction. The aim of this study was to determine the diagnostic value of protein Ki67 staining in atypical pap smears of postmenopausal women. Methods: In a case-control setting, pap smears of 75 women with an atypical pap smear (case group) and 75 with normal pap smears (controls) were obtained before and after estrogen treatment. Afterward, samples were exposed to the monoclonal antibody Ki-67 (MIB-1) and the immunohistochemically demonstrated Ki-67+ cells were compared. Results: Mean ages of cases and controls were $60.4{\pm}4.5$ and $59.9{\pm}4.3$ years respectively (P=0.50). There was one (2.7%) positive Ki-67 specimen in the case group, without any positive Ki-67 specimen in the control group (P=0.50). Conclusions: Measurement of proliferative activity index in Pap smears restrained with MIB1 is a simple, reliable, and cost-effective method for excluding negatives. This would imply that it might allow a substantial reduction of diagnostic estrogen courses and subsequent Pap smears in postmenopausal women with atypical findings.

  • Background: Under-ascertainment and over-ascertainment are common phenomena in surveillance and registry systems of health-related events. Capture-recapture is one of the methods which is applied to determine the sensitivity of surveillance or registry systems to recognize cancer cases. This study aimed to estimate the number of cancers using data available both in the Cancer Registry Center of Northwestern Iran and in the Population-based Cancer Registry Center of Iran. Material and Methods: The studied population consisted of all cancerous cases in the northwest of Iran from 2008 to 2010. All data were extracted from two resources and entered into Microsoft Excel software. After removing common and repeat cases the data were statistically analyzed using a capture-recapture studies' specific software "CARE 1.4". Estimations were calculated by Chapman and Petersen methods with the approximate confidence interval of 95%. Results: From 2008 to 2010, the number of all cancer cases was estimated to be 21,652 (CI 95%: 19,863-22,101). Sensitivity rate of all cancer cases was 83.9% and that of Population-based Cancer Registry Center of Iran was 52%. It was 93.1% considering both resources. Conclusion: Using two resources and the capture-recapture method rather than a single resource may be a more reliable method to estimate the number of cancer cases.

  • Background: Catastrophic effects of mustard gas as a chemical warfare agent have always been a major problem for those exposed to this agent. In this meta-analysis it was tried to evaluate carcinogenesis, ocular, cutaneous and respiratory complications of mustard gas exposure among Iranians who had been exposed to this agent during the Iran-Iraq war. Materials and Methods: In this meta-analysis, the required data were collected using keywords "mustard gas", "sulfur mustard", "cancer", "neoplasm", "respiratory complications", "ocular complications", "lung disease", "chronic complication", "eye", "skin", "cutaneous complication", "carcinogenesis" and their combination with keywords "Iran", "Iranian", "prevalence", "mortality" and their Farsi equivalent terms from the databases of SID, Iranmedex, Magiran, Pubmed, Science Direct, Google Search engine, Gray Literature and Reference of References. To determine the prevalence of each complication and perform meta-analysis, CMA: 2 (Comprehensive Meta-Analysis) software with a randomized model was used. Results: Of the 542 articles found, 7 national articles, consistent with the aims of this study were selected. Meta-analysis of seven papers revealed that cancer risk, especially cancer of the respiratory system was elevated, so that the relative risk (RR) of cancer role of mustard gas was inconsistent from 2/1 to 4 in this survey. Also prevalence of delayed skin disorders due to sulfur mustard was 94.6%, pulmonary complications 94.5% and ocular complications 89.9%. The incidence of various cancers in victims exposed to mustard gas was 1.7% worldwide where the rate was 2.2% in Iranian victims of the Iraq-Iran war. Conclusions: Based on present study the prevalence of delayed mustard gas related cutaneous, pulmonary and ocular complications is above 90% and risk of carcinogenesis is higher in comparison to worldwide statistics. This may suggest need for long-term and persistent follow-up and rehabilitation procedures for populations exposed to this agent.

  • There have been always some difficulties in target setting and conditioning of acoustic performances or the Korean traditional music hall due mainly to the lack of the information on the sound radiation characteristics of Korean musical sources. As the 2nd experiment succeeding the previous study[1], the radiation characteristics of eight typical Korean traditional musical sources were investigated if precision. The selected musical sources were Geomungo, Haegeum (string), Piri, Taepyeongso (woodwind), Buk, Kwaengguari, Jing (drum), and male Pansori Chang (vocal Performance). The results show that the directivity pattern of each instrument is different and has their own directivity characteristics. Measured directional and spectral characteristics of traditional Korean music sources were implemented into the computation of architectural acoustic measures. Significant differences in the acoustic measures at receiver positions were observed between the results in using the omni-directional source and the directional one. In order to investigate the acoustical characteristics of the instruments depending on the spatial variation four different shapes of halls were introduced including rectangular, fan. horse-shoe and geometrical shapes. Room acoustical parameters such as RT, SPL, C80, LF, STI were calculated at each type or hall. As the results, It was found that the rectangular hall has the most high clarity. lateral energy and STI values among low shapes of halls. It is thought that the suggested source data and design method can be used as a basic reference in the future acoustic design of performance halls for the Korean traditional music.

  • This study finds aesthetic elements and examines their aesthetic sense focusing on the melody of the piri in the completed Jongmyojeryeak with various ideational backgrounds from the views different from the aesthetic sense of Jongmyojeryeak that has been conducted so far. Jongmyojeryeak is to hold a memorial service at the place where the godship of the line of kings and queens in Joseon is set. It is the crystal of Confucian memorial ritual and representative cultural heritage of ancestral ritual culture and is designated as No 1 of national chief, intangible cultural heritage in 1964. Also, on May 18th, 2001, it was registered first in Korea as 'Masterpieces of the Oral and Intangible Heritage of Humanity' designated by UNESCO and was recognized of its superiority. It is not only a representative cultural heritage of ancestral ritual culture having fate with Joseon Dynasty for a long period but also has been recognized as the essence of our music compiling the holistic beauty of artistic forms according to music, songs, and dance created by our ancestors. Also, it has as its background the traditional thoughts including the Confucian thought as well as Yeak thought, Yin-Yang School, Samjae thought (三才思想), and Palgoe thought (八卦思想). This Jongmyojeryeak internalizes landscape beauty, Yojang beauty, natural beauty, magnificent beauty, and harmonious beauty. Landscape beauty can be found in Huimun and Jeonpyehuimun. Yojang beauty is the figure that is only shown in Jeongdaeup. Natural beauty is the skilled performance technique shown in the melody of variations and is connected to natural creation. It is well shown in Huimun and Jeonpyehuimun. Magnificent beauty is well shown in the melody of Botaepyeong movement. And harmonious beauty is the harmonization of dischord in Jongmyojeryeak and is well shown in Jeongdaeup's Somu distinctively showing its aesthetic sense from the view of natural, harmonious beauty in its music.

  • Jeongeup Pungnyu, which can be regarded as a foundation of Hyangje Julpungryu(;string ensemble in Honam Area) best reflects social-spatial characteristics of local Pungryu culture. The close relationship between Daepungryu(wind ensemble) and Julpungryu can be inferred from three points of view. First, Jeongeumun who participated as a musician in the beginning of Hyangje Julpungryu was good at not only performing musical instrument but also dancing. Jeongeumun did not stay in specific musical field. He performed Hyangje Julpungryu, made Daepungryu and used it as dancing music with musicians that participated in Julpungryu. That is why Julpungryu and Daepungryu are not completely separated music. Secondly, according to , Jung Hyungin, who followed the dance of Jeong Jae-Sun with Kim So-Ran, was the first Piri player who learned from Jeongeumun and played Yeongsanhoesang and Samhyeon-yukkak(;wind ensemble). That is, Jeongeup Julpungryu was formed by Jeongeumun and dancer Jung Hyung-in followed Julpungryu and Daepungryu. Based on these findings, it can be inferred that Jeongeup's Daepungryu is fundamentally closely related to Jungeup Julpungryu.

  • This study scrutinizes the titles of serial poems on Japanese Apricot, which have lucid characters on season and time changes, having been appreciated and recited by the scholars in the Choseon Dynasty era and analyses the records of Zhang zi(1153~1235), a writer in Song(宋) Dynasty in China, having presented the objects harmonizing perfectly with Japanese Apricot. The results of this study categorizes the objects of Japanese Apricot appreciation and establishes the landscape characteristics on Japanese Apricot appreciation affiliated with as follows. First, the objects of Japanese Apricot appreciation are categorized into 'form of blossoms', 'natural feature(景物)', 'place of tree planting', 'the picturesque scene(景色)' and 'behavior'. Second, the scholars regarded the single trees whose branches are grotesque as the objects of appreciation and enjoyed them. They preferred white and single petal Japanese Apricot and admired red Japanese Apricot which has Taoism images. Third, they admired pines and camelias which represent fidelity and strength and valued Japanese Apricot with cranes which remind themselves of solitary scholars. Fourth, they appreciated the images of Japanese Apricot reflected on the water, and the poetically inspiring atmosphere where the trees are planted by the window. Fifth, the moon and snow were crucial weather conditions for appreciating. cold weather and time from night to dawn were ideally suited for enjoying. Sixth, they enjoyed blossoms in various fashions like bottling(甁梅), potting(盆梅), green-housing(龕梅), searching(龕梅) and black-and-white painting(墨梅) with a view to seeing blossoms earlier than the usual flowering time. Moreover, they used paper drapes, bead curtains, mirrors and ice lamps for active appreciation. They also listened to the sound of Piri(wind) and Geomungo(string), played go and drew tea with noble and elegant beauties when they enjoyed Japanese Apricot. The scholars influenced by the neo-Confucianism, which contemplates the objects, attached the specific sentiments like memories, grieves, dreams and farewells to Japanese Apricot and appreciated them. As stated above the scholars enjoyed the landscape including the picturesque scene like climate-weather, time-season and human behaviors not to mention the physical beauty of Japanese Apricot themselves and objects in company with Japanese Apricot including animals and plants.

  • In this study, pieces of statements of sinawi successors, which served the ground of sinawi theory of Lee(that are found only in reports and theses) were searched from notebooks or cassette tapes of Lee. Then, this study tried to trace the process that the theory of sinawi was established based on the fieldwork of sinawi and relevant data, and to shed light on the significance. With the understanding from the early days that life of minsokak can be found in musical scenes in the region, Lee wandered around the scenes of minsokak(folk music) in the nation, recorded minsokak, and collected dialogues with successors of minsokak with about 2,000 cassette tapes and 300 notebooks. Especially, in the fieldwork data on sinawi that Lee possesses contain dialogues with the newly found sinawi successors that Lee found in the scene of sinawi in Gyeonggido province, Jeollado province, and Gyeongsangdo province over numerous visits for over 20 years from the early 1970s. Sometimes the record includes improvised sinawi performance. As the fieldwork of sinawi by Lee was conducted comparatively early, there are a lot of testimonies of successors who remember the sinawi scene of the past. Using these data, Lee published theories related to sinawi on reports and theses. His representative thesis is about 'Sinawi Chung'(1979). After listening to the testimony of Younghee Ji, the master of Gyeonggi haegeum sinawi in his first fieldwork of sinawi, he started his research on sinawi chung of piri, daegeum, and haegeum in Gyeonggido province and Honam area. Based on the testimonies on sinawi chung of 11 sinawi successors, Lee published 'Sinawi Chung'. In 1987, he extended the scope his research to sinawi-kwon(圈), which includes Gyeongnam area, found 12 new sinawi successors in Gyeonggi, Honam, and Gyeongnam areas, and based on their testimonies, complemented the theory of sinawi chung and published it. Fortunately, most of the dialogues with sinawi successors quoted in his reports or theses are recorded in his notebooks or cassette tapes. When these data are released, it is expected that a new theory of sinawi or minsokak will be born.
