Jeju province is the highest area about obesity(1st), alcohol consumption(2nd) and male smoking(2nd) among sixteen Korean provinces by the report of Statistics Korea: 2013 community health survey. Therefore, it is assumed that the incidence rate of colon, liver, lung and breast cancer can be high. The purpose of this study is to test these cancer's incidence and mortality trends and compare comparability with national average. The Joinpoint regression model and permutation tests for identifying changes and parallelism in trend were used to test registered data at Jeju Regional Cancer Registry from 1999 to 2012. In male colorectal cancer, Average Age Percent Change(AAPC) of Age-Standardized incidence Rate(ASR) was 8.4% per year(p-value<.000) and the hypothesis of parallelism with Korean male average was rejected because of steep increasing of Jeju male patients' AAPC(p-value=.047). In male liver cancer, AAPC of ASR was -2.98 % per year(p-value<.000) and parallelism with Korean male average was rejected because of sluggish decreasing of Jeju(p-value=.026). In male lung cancer, the ASR parallelism with Korean male average was rejected(p-value=.009) because Jeju patients APC(4.37% per year) was increased during 2006~2012. This study demonstrates that AAPC and Trends of male colon, male lung and male liver were difference from national average. Further studies are needed to understand its causes.

A tick survey was conducted to determine the relative abundance and distribution of ticks associated with selected mammals in the Republic of Korea (ROK) during 2008-2009. A total of 918 ticks were collected from 76 mammals (6 families, 9 species) captured at 6 provinces and 3 Metropolitan Cities in ROK. Haemaphysalis longicornis (54.4%) was the most frequently collected tick, followed by Haemaphysalis flava (28.5%), Ixodes nipponensis (7.6%), Ixodes pomerantzevi (4.8%), Ixodes persulcatus (4.6%), and Haemaphysalis japonica (0.1%). Adults (57.0%) and nymphs (28.7%) of Ixodes and Haemaphysalis spp. were collected most frequently from medium or large mammals in this survey, while few larvae (14.3%) were collected. Hydropotes inermis was the most frequently captured mammal (52.6%), with a 16.4 tick index and 5 of 6 species of ticks collected during this survey. H. longicornis (69.7%) was the predominant tick collected from H. inermis, followed by H. flava (22.2%), I. persulcatus (6.1%), I. nipponensis (1.8%), and H. japonica (0.2%).

"Boram" is a new $F_1$ hybrid of rapeseed (Brassica napus L.) with early maturing, high yield and high oleic acid. This cultivar was developed from the cross between Mokpo-CGMS (male steile line) and 8634-B-1-3-1-8 (restore line) for the production of edible oil and biodiesel in 2006. Yield trials were conducted from 2007 to 2008 and regional adaptation trials were examined at four locations in 2008. "Boram" has green and parted leaf, yellowish flower, and black seed coat. The ripening period of "Boram" is similar to "Sunmang", but 3 days faster than "Tammiyuchae". The average seed yield of the regional adaptation trials was 424 kg/10a, which was 11 and 48% higher than "Sunmang" and "Tammiyuchae" variety. Total oil content of "Boram" was 44.2%. In fatty acid composition, "Boram" has no erucic acid. However, oleic acid content is 68.5%, which is 3.7 and 5.4% higher than "Tammiyuchae" and "Sunmang". And total glucosinolate content was 2.27mg/g. Therefore this variety is recommended as a leading variety at southwestern areas including Jeonnam, Jeonbuk and Kyeongnam provinces and Jeju island of Korea.

The results of the survey conducted mainly in the Gyeongsangnam-do province are as follows : First, 31.6% (65 schools) of the total elementary schools in the eight Cities Dong Districts of Kyungsangnam-Do Province are larger than the appropriate schools. 51.9% (107 schools) are the most suitable schools. The number of small schools with less than 300 students was 35 (17.0%). Of the 138 elementary schools in City Up-Myun districts, 11.6% (16 schools) account for big schools larger than the appropriate size. The number of schools with adequate size is 18.1% (25 schools), while 97 schools with 70.3% of small schools occupy the majority. Of these, 10.1% (14 schools) account for less than 150 small schools. Second, three large schools (2.2%) are larger than the appropriate schools among the 137 elementary schools in the nine districts of Gyeongsangnam - do, and 17 schools (12.4%) are suitable for small schools. Less than 300 small schools 117 schools (85.4%), of which 111 small schools (81.0%) accounted for the majority. Third, as a result of the analysis by the subdivision into the provinces, municipalities, and counties, small - scale schools accounted for the majority of municipalities and counties. Therefore, considering the local environment, it is necessary to establish appropriate school proper size policy differentiated from municipal school.

The land under Japanese-type names remains in the Korean cadastral record as an official register due to land exploitation, land and field survey programs, and the forceful name-changing system of Japan during its colonial era. This research aims to find a measure to survey and organize such land. Research details are as follows. First, this research put together the purpose and status of land exploitation in the Japanese colonial era. Japan wanted to reduce its population through agricultural emigration of the Japanese and increase food supply by producing more crops in Joseon. Therefore, land of three southern provinces, the breadbasket of Korea, was intensively plundered. Secondly, this research organized how Joseon people changed their surnames into Japanese-style ones. The initially voluntary name-changing system became mandatory and about 3.22 million households (79.3%) reported the change of their names. Thirdly, this research established a process to survey land under Japanese-style names. Fourthly, this research yielded visible outcomes as a result of the pilot program. Especially, it revealed 718 lots as land under Japanese-style names and 8 lots as land under the names of Japanese. Fifthly, this research presented internal & external collaboration and cooperation measures for surveys.

This paper deals with an analysis of crustal movement for the sourthern part of Korean peninsula using GNSS (Global Navigation Satellite System) data. An earthquake of more than 5.0 occurred in the southeastern region of the Korean Peninsula, and it is necessary to evaluate the risk of earthquakes in various ways.In order to reveal long-term tectonic movement patten in Pohang and Gyeongju provinces, we derived crustal movement parameters related with elastic theory. We used GAMIT/GLOBK for analyzing seven-year interval GNSS data of CORS (Continuously Operating Reference Stations). The azimuth of velocity vectors trended generally about 110° with an mean magnitude of 31mm/yr.The main characteristics of the strain change for seven-year in Korea obtaind from our study. Direction of the principal axis of the maximum compression is ENE-WSW as a whole, through there are some exceptions. The mean rate of the maximum shear strain change is (0.11±0.07)μ/yr, that is approximately one third that of Chubu district, Central Japan. Taking into account our results, the mean rate of maximum shear in southern part of Korean peninsula is considered as reasonable. The mean azimuth of principal strain is about (85.4°±26.8°). There are some exceptions of azimuth because the average azimuth differ from the left and right side in Yangsan fault which are about (73.2°±21.5°) and (105.2°±17.0°) respectively, It is noteworthy that the high seismicity areas in the southern part of Korea peninsula almost coincides with the area of large strain rate. As a conclusion, it could be stated that the our study represents the characteristics of crustal deformation in the southern part of peninsula, and contributes to the researches on earthquake disaster management.

Background and Objectives: Autosomal recessive non-syndromic hearing loss (ARNSHL) with genetic origin is common (1/2000 births). ARNSHL can be associated with mutations in gap junction protein beta 2 (GJB2). To this end, this cohort investigation aimed to find the contribution of GJB2 gene mutations with the genotype-phenotype correlations in 45 ARNSHL cases in the Kurdish population. Subjects and Methods: Genomic DNA was extracted from a total of 45 ARNSHL families. The linkage analysis with 3 short tandem repeat markers linked to GJB2 was performed on 45 ARNSHL families. Only 9 of these families were linked to the DFNB1 locus. All the 45 families who took part were sequenced for confirmation linkage analysis (to perform a large project). Results: A total of three different mutations were determined. Two of which [c.35delG and c.-23+1G>A (IVS1+1G>A)] were previously reported but (c.299-300delAT) mutation was novel in the Kurdish population. The homozygous pathogenic mutations of GJB2 gene was observed in nine out of the 45 families (20%), also heterozygous genotype (c.35delG/N)+(c.-23+1G>A/c.-23+1G>A) were observed in 4/45 families (8.8%). The degree of hearing loss (HL) in patients with other mutations was less severe than patients with c.35delG homozygous mutation (p<0.001). Conclusions: Our data suggest that GJB2 mutations constitute 20% of the etiology of ARNSHL in Iran; moreover, the c.35delG mutation is the most common HL cause in the Kurdish population. Therefore, these mutations should be included in the molecular testing of HL in this population.

This study investigated the distribution and overwintering of Phanuromyia ricaniae(Hemiptera: Platygastroidea), an egg parasitoid of Ricania sublimata(Hemiptera: Ricaniidea), in order to acquire basic information for biological control. P. ricaniae is distributed in some areas of Gyeonggi, Chungcheong, Jeolla, and Gyeongnam provinces. P. ricaniae is highly prevalent in the southwestern plains, with a tendency to expand to the northeastern area of Korea in line with the dispersal of R. sublimata. The parasitism of P. ricaniae was 1-8% in the field, and the highest in Suncheon, followed by Gurye and Gongju. P. ricaniae overwintered inside the eggs of R. sublimata from September to June of the next year, and transformed into adults in June. The rapid cold-hardiness of P. ricaniae was the highest in the egg state.

This study investigated the influence of media sports contact motivation on direct sports participation in order to induce direct sports participation through media sports. In this regard, this study aimed to provide the basic data of media sports and sports participation by studying the effects of consumer's exercise commitment and exercise duration. From April 1, 2019 to April 31, 2019, a survey was conducted on 300 males and females in G and J provinces. To determine the purpose of the study, IBM's SPSS Ver. 21.0 and AMOS Ver. The analysis was performed using a statistical program of 21.0. The results of the study are as follows. First, media sport contact motivation was found to have an effect on exercise commitment. In addition, media sports contact motivation was found to have an effect on exercise persistence and sports participation. In addition, exercise commitment was found to have an effect on exercise duration, and exercise duration was found to affect sports participation. Second, in terms of media sports contact motivation and sports participation, exercise persistence had a mediating effect. In addition, it was found that exercise commitment had a mediating effect on the relationship between media sports contact motivation and exercise persistence, and exercise persistence had a mediating effect on the relationship between exercise commitment and sports participation. Third, media sports contact motivation did not have a direct effect on sports participation. Also, exercise immersion has no mediating effect in the relationship between media sports contact motivation and sports participation. However, in terms of media sports contact motivation and sports participation, exercise commitment and exercise persistence showed a double mediating effect.
