As the low birth rate and aging phenomenon intensify, many local governments are facing a difficult situation of not only reducing population but also for securing financial resources. The national average fiscal independence is not increasing, and the fiscal gap between local governments has not been resolved. Accordingly, the Hometown Love Donation System, which provides tax incentives for donations to local governments, was included in the current government's 100 major national tasks and roadmap for autonomous decentralization. The hometown tax system was introduced in Japan in 2008 and has been contributing to securing financial resources of local governments, and has been contributing to regional development in recent years by using local specialties as return products, but concerns about overheating of competition are also growing. In Korea, the National Assembly and local governments have continuously reviewed the introduction of the hometown tax system. In addition, it is proposed to organize and operate a research conference about the suitabity of the environment of Jeju in order to minimize trial and error in the introduction and implementation of the system based on the case of Japan's hometown tax, taking into account domestic and Jeju special selfgoverning conditions. In the future, further research is needed in policy making and related systems for the donation deduction system.

Ostrea denselamellosa and Eriocheir japonica samples were collected from the Seomjin River in 2019 as part of the “Research of Host-Associated Bacteria” research program. Almost 200 bacterial strains were isolated from the O. denselamellosa and E. japonica samples and subsequently identified by 16S rRNA gene sequencing. Among the bacterial isolates, ten strains possessed greater than 98.7% sequence similarity with published bacterial species that had not previously been recorded in Korea. These species were phylogenetically diverse, belonging to three phyla, four classes, seven orders, and eight genera. At the genus and class level, the previously unrecorded species belonged to Pseudoalteromonas, Aliivibrio, Rheinheimera, Leucothrix, and Shewanella of the class Gamma-proteobacteria, Olleya of the class Flavobacteriia, Algoriphagus of the class Cytophagia, and Lactococcus of the class Bacilli. The previously unrecorded species were further characterized by examining their Gram staining, colony and cell morphology, biochemical properties, and phylogenetic positions.

Background: Forward head posture (FHP) is a postural alignment of the cervical vertebrae that leads to increased gravitational load on cervical segmental motions. The overhead arm lift test assesses the ability to actively dissociate and control low cervical flexion and move the shoulders through overhead flexion. Objects: The purpose of this study was to explore muscle activities in the upper trapezius (UT), serratus anterior (SA), sternocleidomastoid (SCM), and lower trapezius (LT) alongside changes in head position during the overhead arm lift test in individuals with FHP. Methods: Fifteen subjects with forward head posture and fifteen subjects with normal subjcects were enrolled in this study. The patients performed the overhead arm lift test, and muscle activities of the UT, SCM, SA, and LT were measured using surface electromyography and by evaluating changes in head position. Independent t-tests were used to detect significant differences between the two groups and Cohen’s d was calculated to measure the size of the mean difference between the groups. Results: The FHP group demonstrated significantly increased muscle activity of the UT (32.46±7.64), SCM (12.79±4.01), and LT (45.65±10.52) and significantly decreased activity in the SA (26.65±6.15) than the normal group. The change in head position was significantly higher in the FHP group (6.66±2.08) than the normal group. Effect sizes for all parameters assessed were large between the two groups. Conclusion: The subjects with excessive FHP displayed were unable to fix their heads in position during the overhead arm lift test. The overhead arm lift test can thus be used in clinical settings to confirm control of the neck in these subjects.

DNA 바코드를 기반으로 하여 외국발 국내 입항 선박에서 검출되는 편승자 해충(hitchhiker insect pests)에 대한 모니터링을 수행하였다. 국내 입항 선박 조사는 2018년 6월 1일부터 2018년 9월 17일까지 약 109일간 111개 선박에 대해 실시하였다. 모니터링 대상 해충은 ‘보고잡기법(simply collecting method by hands)’으로 확보하였으며, 총 336개체에 대해 종동정을 실시하였으며, 이를 통해 확보된 정보들은 선박정보(선박명, 선박번호, 출항지, 입항지), 조사정보(조 사일, 채집시 표본 상태, 조사자), 유전자 분석 정보(프라이머 정보, 서열판독 결과), 분자생물학적 종동정 정보(NCBI GenBank Accession No., NCBI Blast Searching Results, BOLD Identification Request), 분류학적 통합종 확증 정보(목명, 과명, 종명, 동정자, 비고) 등으로 구분하였으며, MS-Excel을 이용하여 각 필드값에 맞게 기초정보를 입력하였다. 이를 기반으로 하여 편승자 해충에 대한 선박 경로에 따른 편승 양상뿐만 아니라, 월별, 분류군별, 미서식종별로 편승 양상을 분석하였다. 그 결과, 편승사례는 선박 경로에 따라서는 중국에서 출항하거나 중국을 거쳐 편승하는 사례가 207건, 월별로는 9월이 134건, 분류군별로는 나비목이 208건으로 가장 많았다. 특히, 미서식종별 편승 양상에서 는 총 3목 9과 13종 21개체가 국내 입항 선박에서 검출된 것으로 나타났으며, 이 중 2목 6과 9종 15개체는 살아있는 상태로 채집된 것을 확인되었다. 이와 같은 결과로 볼 때, 앞으로 더욱 많은 정보가 확보된다면, 현재의 통계 분석 방법은 편승자 해충의 모니터링뿐만 아니라 대상 해충의 위험성 평가 및 검역검사에 매우 효율적인 정보를 제공할 수 있을 것으로 사료된다.
