Rotylenchus arsenjevi are reported for the first time in Korea. The Korean species differs slightly by having a hemispherical lip region and a slightly shorter tail than the original description (c=38.2-68.7 vs 36-41). Male was founded firstly from Korea and described. Geocenamus adakensis were collected a second time from Korea at a different locality and habitat. The measurements were compared with original description and the firstly collected specimen in Korea.

Objectives: Tremor is a common disorder causing abnormal movements, it is defined as, "rhythmic, involuntary movements of a part of the body against ones own volition.". The purpose of this study is to report the effects of Korean Medicine (Acupuncture and herbal-medication) for oromandibular tremor resulting from Deficiency Syndrome. Methods: We treated 6 patients suffering from oromandibular tremor who received hospital treatment in DongEui Medical Center from March to June in 2015. Results: After the treatments, oromandibular tremor decreased or disappeared. And some other accompanying symptoms were improved. Conclusions: These results suggests that Korean medical treatments (Acupuncture and herb-medication) might be effective for treating oromandibular tremor resulting from Deficiency Syndrome.

Cleft lip and palate is the most common teratologic condition of oromaxillofacial units, probably associated with genetic and environmental causes. The goal of cleft surgery is to optimize facial esthetics and stomatognathic function while minimizing growth disturbances from surgical intervention. In this article, the author suggests the recent surgical strategies that minimize cleft nasal deformity and midfacial skeletal constriction. From the author's surgical experiences and literature reviews, only considerate surgeries would achieve functional improvement and facial esthetics in patients with cleft lip and palate.

Maxillary growth is hindered by the restricting pressure from the scar tissue formed after lip closure and palate closure surgeries of the cleft. Therefore, the anteroposterior skeletal relationship of both jaws exacerbates as patient grows. Conventional facemask treatment is valuable for dentoalveolar compensatory treatment and for very mild maxillary hypoplasia. To achieve further maxillary protraction, bone-anchored facemask or bone-anchored maxillary protraction can be attempted. For moderate maxillary hypoplasia, surgical orthodontic treatment after growth completion can be an efficient treatment reducing uncontrollable problems. For moderate to severe maxillary hypoplasia, distraction osteogenesis (DO) can be used alone or with later surgical orthodontic treatment. To compensate the severe relapse after DO, overcorrection and bone plate placement after DO are recommended. In case of hypernasality, maxillary anterior segmental distraction osteogenesis can be chosen to prevent exacerbation of the hypernasality.

A technical refinement for oral commissure reconstruction is presented. The oral commissure has an important role in oral sphincteric function. Once lost, the oral commissure is very difficult to restore and therefore, reconstruction of the oral commissure requires prevention of this function as well as prevention of microstomia. Trauma and tumor excisions are the most frequent reasons that will necessitate reconstruction of the oral commissure. Direct approximation of the wound margins after resection of the corner of the mouth could easily induce microstomia and difficulty in opening. Thus case presented here deals with distortion of noraml mouth angle and acquired microstomia due to burn and tissue deface following shotgun and explosive wounds. The a mucosal flap approach was used to rehabilitate a natural looking mouth angle showing satisfactory results function and esthetic wise.

Our Goal of modified segmental osteotomy on maxilla accompanied by mandibular anterior subapical osteotomy was to get the best results from patients of bi-alveolar or bi-maxillary protrusion. In this study, cephalometric and photo (en face, profile) analysis have been compared to define the soft tissue change after surgery. Lip protrusion was efficiently reduced and nasolabial angle was much obtused. Although nose was a little widened, it was quite acceptable. Blood circulation on osteotomized segment was well maintained. This relatively simple methods could be successfully applied to many patients.

동아시아에 위치한 한반도는 여름철에 강우량의 70%가 집중되어 홍수로 인한 피해가 주기적으로 발생한다. 홍수피해를 일으키는 호우는 주로 여름철의 집중호우와 태풍으로 구분할 수 있다. 집중호우는 여름에 우리나라에 한 지역에서 짧은 시간에 많은 양의 강우를 발생시킨다. 태풍은 연평균 3개 정도가 열대 지방에서 발생하여 주기적으로 우리나라를 내습하여 극심한 강우와 강풍으로 큰 피해를 야기시키고 있다. 따라서 본 연구에서는 한반도의 23개 강우관측소에서 관측된 강우자료를 이용하여 태풍과 집중호우로 인해 발생한 호우사상을 구분하여 특성을 비교 분석하였다. 이를 위해 한반도에서 발생한 강우사상을 집중호우와 태풍으로 분류하여 우리나라에 영향을 준기간을 분석하였고 각각의 기간 동안에 발생한 연초과강우량을 구축하였으며 비교분석을 위하여 호우발생원인을 구분하여 연초과강우량을 구축하였다. 분석방법으로는 호우원인 별로 구축된 강우량 자료를 호우사상의 크기와 발생원인에 대한 비교 분석을 수행하였다.

세계 각국은 새로운 유비쿼터스 환경변화에 맞추어 전략적 차원에서 u-IT에 대한 연구와 다양한 프로젝트를 추진 중이다. 특히 유비쿼터스를 지역수준으로 적용 시 지역 구성원들의 삶의 질이 향상되고 편익을 직접적으로 체감할 수 있는 효과가 있다. 유비쿼터스 환경의 중심 기술 중 하나인 RFID는 대역별로 다른 특징을 가지고 있어 단일 대역 RFID는 제약조건이 있으며, 이를 극복하고 보다 입체적인 정보와 서비스를 제공하기 위하여 여러 대역의 RFID를 통합하는 기술이 필요하다. 따라서 본 연구에서는 새로운 u-City 서비스 모델로써 u-Zone 서비스 구축 시에 필요한 13.56MHz와 2.45GHz 주파수 대역의 듀얼밴드 RFID Manager를 개발한다. RFID Manager는 u-Zone 서비스의 임베디드 하드웨어인 Base Station에 탑재하는 응용 소프트웨어로서 리더에서 입력되는 정보를 u-Zone 통합 서버 시스템에 전달하는 역할을 한다.

We identified the five root-lesion nematode species, Pratylenchus crenatus, P. fallax, P. kumamotoensis, P. panamaensis and P. penetrans from intercepted in quarantine inspection over the past five years. Their diagnostic characters are including number of lip annuli, stylet length, shape of the labial region, presence or absence of males, structure of lateral fields, shape of spermatheca, length of the post-vulval uterine sac and shape of tail and so forth. We described the photos, measurements and morphological characters.
