A new species of the Cletopsyllidae belonging to the genus Isocletopsyllus Huys and Lee, 1999 is described from the materials collected from subtidal sandy bottoms at Jeju Island and Ulleung Island, Korea. So far, only two species of the genus Isocletopsyllus, viz. I. tertius (Por, 1964) from Israel and I. quartus (Soyer, 1966) from Banyuls-sur-Mer (France) are recorded, both from the Mediterranean Ocean. The new species can be clearly distinguished from its congeners by the combination of the following characters: (1) female antennule with a large process on the outer margin of first segment, (2) caudal rami with a bulbous proximal inner expansion, and shorter than those of other species (about four times long as wide in the new species), (3) second segment of P1 exopod with a short rod-like inner seta, (4) sexual dimorphism presented in the second endopodal segment of male P2, not in exopod of P4, and (6) female P5 with a very long exopod with very short second outer seta. A table comparing the modifications of swimming legs in the family Cletopsyllidae Huys and Lee, 1999 is presented. This is the first record of this family from Korea.

A new dragonfly species, Nannophya koreana sp. nov., is described from Korea on the basis of morphology and mitochondrial cytochrome oxidase c subunit I (COI) gene sequences. Nannophya materials from Korea and other areas in Southeast Asia were compared. The new species was previously recognized in Korea as the endangered pygmy dragonfly Nannophya pygmaea Rambur, 1842, which is widely distributed in insular and peninsular Southeast Asia. However, male adults of the Nannophya population in Korea could be distinguished from other N. pygmaea populations by the presence of a thick, incomplete black stripe on the lateral synthorax that terminated at half-length (vs. continuous to wing base), light orange (vs. red) anal appendages, and 4-5 (vs. 2-3) black teeth on the ventral superior appendages. In addition, the body length of N. koreana was generally larger (1.2-1.4 times) than that of N. pygmaea, regardless of life stage. COI gene sequences from the two groups exhibited substantial genetic differences (>12%), thereby sufficiently substantiating their differentiation. The taxonomic status, distribution, and habitat of the new species are discussed.

Heterorhabdus papilliger (Claus, 1863) is newly reported from the Tsushima Warm Current realm of the southern Korean waters. Its morphological diagnostic characteristics generally agreed well with the original description and the previous records of H. papilliger. The female of H. papilliger can be recognized by the genital somite, which in lateral view has a more or less rounded genital prominence and an uninflated posterior ventral margin; the second exopodal segment of male right leg 5 with the medial projection with a large, rounded, plumose proximal lobe, and a poorly developed distal lobe. The genetic difference for the partial mtCOI gene between Korean specimens and H. papilliger from Spain and Japan of the same clade is 0.4%, while the difference between Korean specimens is 0.5%. However, the interspecific difference for the mtCOI gene between H. papilliger from the Korean waters and the other Heterorhabdus species is in the range of 14.7-20.8%, suggesting that the former is a valid species.

Objectives The aim of this study done as pilot study is to analyze the current state of patients who have low back pain through registry. Methods This study is done under approval of Gil Oriental Medical Hospital of Gachon University, Oriental Medical Hospital of Sangji University, Jecheon Oriental Medical Hospital of Se-Myung University IRB. Among subjects who signed the consent form by their own will, we decided whom to register as subjects of this study by the standard of selection and exception. We collected the sociological investigation, character of low pack pain, degree of symptom which they felt before and after the hospitalization from registered subjects. Results 1. The number of the subjects is 16. The average age is 41.0. 9 of them are female, 7 of them are male. Most of the subjects have history illness which has connection with low pack pain. 2. According to the patient's free description of the back pain, 6 of them suffered throbbing pain. And 8 of the patients have chronic pain, 6 of them have intermittent pain of back pain analysing the character of the low back pain. They answered the pain lasted for 47.6 minutes on average. 3. About the change on the average R.O.M. of L-spine, R.O.M. of Lateral bending, Extension, Flexion, Rotation has increased after leaving the hospital compared with before hospitalization. 4. The amount of discomfort or strength of pain, which was checked by VAS on the day of leaving the hospital, has decreased than they were before the hospitalization. And there was the improvement on the dysfunction score and EQ-5D. Conclusions Through this study, we specifically analyzed the symptoms of the low back pain by accumulating the analysis about the symptoms using several indicators and description which is freely spoken by patients about their symptoms. Further research is expected to complete multi-center registry by building registry and by using it, to get various epidemiologic informations about low back pain.

Background: Israeli Arabs are considered as a developing society characterized by poverty and high levels of smoking among men. The purpose of this study was to describe their incidence, mortality and survival rates for oral and pharyngeal cancer between the years 1970-2006. Studies such as this in the Arab world, where the population is almost the same as the Arab population in Israel, are rare. Methods: The incidence and survival data were derived from all relevant registered data at the National Cancer Registry. The group of lesions included cancer of the lips, tongue, buccal mucosa, floor of the mouth, salivary glands, gums, palate and pharynx. Morphological description was according to WHO classification. Results: Most diagnosed patients were male. The mean age was 54.4 years, and mean years of survival were 3.83. The oropharynx was the most common site (28.3%) while the palate was the least frequent (3.12%). Squamous cell carcinoma (SCC) was the most common histological feature (66.3%), while basal cell carcinoma (BCC) was the least (3.9%). The overall 5 years survival rate was 59.4%, this being highest for BCC (82.1%), while SCC was significantly lower (56.2%) (p<0.001). Lip cancers survived better than other sites. Conclusions: Data from this society are similar to other developing societies in the majority of the results. The incidence of oral and pharyngeal cancer is lower among the Arab population, in comparison to the Jewish population in Israel.

In our culture, the term, "be like", is frequently used. There are expressions such as "feminine-looking dress" and "manly style" relating to this term when we describe the styles of clothing. This study addresses the question on which type of garment would be selected under the description of the term, "be-like", in relation to gender. This term reveals the preconception of gender as being feminine or masculine according to the styles and colors of clothes. A group of 362 college students from Seoul and Gyeonggi area was surveyed fur the study The statistical analysis of SPSS 10.0 was applied f3r analyzing the data, and the significant variances were reviewed by the basic statistics, multi-variate and T-test. The results are as follows: First, the details of clothes imply the preconceived idea of gender. As a result, women's blouses and skirts were selected as the most feminine upper and bottom garments. The Y-shirt and T-shirt were selected as the most masculine upper garments. However, in contrast to the . skirts being the most feminine bottom wear, the pants were not significantly recognized as the most masculine ,clothes. Second, the variances of the survey show that the female students are more conscious of the sexual identity expressed in clothes than the male students. Third, the styles of clothes reflect the general understanding of what is considered to be "feminine or not feminine" and "masculine or not masculine" In conclusion, this study has discovered that the certain characteristics of gender are predominantly implicated in the styles length, and color of clothes. Both men and women responded differently in defining their idea of "femininity" and "masculinity". Nevertheless, there still exists strong preconception of what is considered to be feminine or masculine, and it affects the choices people make in selecting clothes.

Polycythemia vera is one type of myeloproliferative disorder which occurs due to the clonal proliferation of hematopoietic stem cell related to the production of leukocyte and megakaryocyte which produces a little less than erythrocyte. Polycythemia vera has a peak incidence in the sixth decade of life with males affected slightly more frequently than females. Vasquez first described polycythemia vera as an autonomous erythrocytosis in 1892, and a further description, delineation of the disease process and a complete course outline were made in 1899, 1903 and 1938, respectively. Symptoms include pruritus, tinnitus, vertigo, gastrointestinal (GI) pain, and bleeding gums. Hyperuricemia and hyperuricosuria are present in about 40% of these patients. Complications are hemorrhage, thrombosis, post-polycythemic myeloid metaplasia, and leukemic transformation. In case of surgery, complications such as hemorrahge and thrombosis are highly likable to happen. We report a case of preoperative and postoperative of a 63-year-old male, who was diagnosed as oral cavity cancer in the mouth floor, with known history of hypertension and polycythemia vera. We considered that conservative management would be an advisable treatment for patients with uncontrolled systemic disease.

Purpose: The nasal bone fracture is known as the most common facial fracture. Several authors reported the classification of nasal bone fracture. Stranc classified the type of nasal fractures based on a pattern of impaction and level of injuries. Stranc classification proposed here is based on careful clinical observation and relates to both treatment and prognosis. The aim of this study is to determine any predictive value to the preoperative classification of nasal fracture, using the description by Stranc and Robertson. Methods: We reviewed 310 patients with nasal bone fracture treated at our hospital for last two years. Results: Lateral impact type of nasal bone fracture predominated more than frontal impact in the ratio of 2.3:1. The most common type of Stranc classification was lateral impact plane I(48.4%). Male predominated more than female in the ratio of 3:1. The most frequent age group was first decade(27.1%), second decade in frontal impact(30.5%), first decade in lateral impact (30.7%). The most common etiology was violence (31.3%) followed by slip down(21.3%), and traffic accident(18.1 %).The most common associated fracture was orbital(22.9%) followed by zygoma(10%), and maxilla (6.1%). The most common complication was septal deviation(20.0%) in frontal impact, and nasal deformity (26.0%) in lateral impact. The incidence of nasal deformity in lateral impact(26.0%) was more higher than frontal impact(15.8%) Conclusion: By assessing the pathomechanics and resultant degree of injury to the nasal skeleton, a better understanding of the treatment plan and prognosis was obtained. Using this information, satisfactory informed patient consent can be obtained.
