  • To determine whether personal history of lactation in premenopausal women influence bone mineral density, a cross-sectional study was conducted. One hundred eighty-four premenopausal women were selected from women who had been checked for bone mineral density by dual energy x-ray absortiometry in lumbar spine, femoral neck, Ward's triangle, and trochanteric site at general hospitals in Seoul and Pusan. They completed a questionnaire including life style factors and reproductive history. In the data analysis, Pearson correlation coefficients were used to test any association between individual variables and bone mineral density and a statistical comparisons between long term lactation(>24 months) and short term lactation(<24 months) were made by one way analysis of covariance. The results were summarized as follows: 1) There was no significant difference in the bone mineral density of the lumbar vertebrae in premenopausal women between the long term lactation group(>24months) and the short term lactation group(<24months). 2) There was no significant difference in the bone mineral density of the femur neck, Ward's triangle, and trochanteric site in premenopausal women between the long term lactation group (>24months) and the short term lactation group (<24months). Considering these results, we suggest prospective studies that measure bone mineral density before and after, in addition to those during lactation. We also suggest the further study with premenopausal women less than 35 who have achieved peak adult bone mass.

  • 1996년에서부터 1999년까지 일본 Kochi현의 Shirano-hana에서 채집된 청베도라치과 어류 6개채 (체장 20.6~52.0 mm)률 채집하여 동정한 결과, 지금까지 일본에서는 서식이 보고되지 않은 Istiblennius dussumieri (Valenciennes, 1836)로 확인되어, 일본산 미기록종으로 보고한다. I. dussumieri는 가슴지느러미 연조수가 14개, 척추골수가 38~42개, 안상피돌기는 가지가 나있고, 둥지느러미에는 파상형의 무늬가 있으며, 체측에는 7~10개의 어두운 횡대가 있으며, 양턱에는 견치가 없다는 점이 특징적이다. 본 종은 Kuroshio 난류에 의해 이동되어 서식하고 있는 것으로 사료되나, I. dussumieri의 지리적 분포에서 서태평양 일대의 최북단 출현 지역으로 나타나고 있어 주목되었다.

  • A 31-year-old male with the complaint of severe limitation of mouth opening was referred to our department of Chonbuk National University Hospital. The physical status of the patient was hyposthenic. Extraoral examination showed no condylar movement of the both temporomandibular joints, no pain, no facial swelling or paresthesia. Intraoral examination showed several cervical caries on the upper anterior teeth, and gingival swelling on the whole dentition. Transcranial view showed no condylar movement, and narrowing of joint spaces. Chest P-A view showed straightening of thoracic, lumbar spine, and squaring of vertebrae of the same spines. Conventional lateral radiograph of cervical spine showed calcification of the intervertebral ligament. Computed tomograph showed extensive bone formation between temporal bone and the condylar head at both sides. Laboratory findings showed positive reaction on HLA-B27 histocompatibility antigen and increased level of IgA, IgG, ESR. Based on the clinical, radiographic, and the laboratary findings, final diagnosis was made as bony ankylosis of the both temporomandibular joints secondary to ankylosing spondylitis.

  • The purpose of this study was to determine the reliability of distance measurements from the medial border of the scapula to the spinous process of the thoracic vertebrae when obtained using tape and photography measurements. The study included 20 healthy subjects (10 males, 10 females); for a total of 40 scapula measurements. The distance measurements made using tape or photography methods were conducted with the subject in a standing position. Repeated tape and photography measurements were conducted in two sessions on different days by two examiners to assess the inter-rater and intra-rater reliability of the two methods. The reliability of scapular distance measured using tape and photography methods was tested using intraclass correlation coefficients (ICC(3,1)) and the standard error of measurement (SEM). The inter-rater reliability of the tape measurement method was excellent (ICC=.77) and the intra-rater reliability was fair to good (ICC=.74). The inter-rater and intra-rater reliabilities of the photography measurement method were excellent (ICC=.76 and .76 respectively). Our results suggest that photography measurement is an objective and qualitative measurement tool for scapular distance measurements.

  • 자동차 충돌에 의하여 편타성 손상이 일어나게 되는데, 대부분 경추부분에서 발생한다. 이러한 편타성손상의 메카니즘은 아직까지 명확히 밝혀지지 않고 있다. 본 논문에서는 다물체 경추에 근육을 부착한 모델을 만들고, 부착된 근육에 follower load 개념에 근거한 최적화방법을 이용하여 계산된 초기힘(preloads)를 가하였다. 경추모델에서 추체, 추간판 및 근육은 인간의 해부학적 정보와 일치시켜 제작되었다. 이번 연구의 목적은 경추모델에 부착된 근육에 초기힘이 존재할 때 초기힘의 편타성 손상에의 영향을 조사하는 것이다. 결론적으로, 초기힘이 존재하는 근육-경추모델의 경우가 초기힘이 존재하지 않는 모델에 비하여 좀더 실제와 일치하는 경향성을 보여주었다.

  • Three leptocephali (22.2, 22.7, 56.0 mm in total length) collected from the East/Japan Sea were identified by morphological and genetic analyses as belonging to the genus Scolecenchelys (Anguilliformes, Ophichthidae). Morphologically, the specimens were characterized by 148-158 myomeres, 10 gut swellings, dorsal fin origin above middle of the body, and 6 postanal melanophores between the anus and the caudal margin. An analysis of an 849-base pair 12S rRNA sequence of mitochondrial DNA showed that sequences are concordant with those of adult Scolecenchelys fuscogularis (genetic distance = 0.001). Furthermore total number of myomeres is consistent with the total number of vertebrae in adult S. fuscogularis. This study provides the first description of the morphological characteristics of S. fuscogularis leptocephali and their variations with size. The Korean name of S. fuscogularis is "Ga-neun-mul-baem", established by Ji et al. (2012).

  • Objectives: The purpose of this study is to investigate the research about using tuina therapy for depression and to determine its efficacy. Methods: All relevant articles were searched in the China National Knowledge Infrastructure using the terms 'tuina' and 'depression'. Results: Forty-one studies were selected, 34 randomized controlled trials (RCTs) and 7 prospective studies. The Chinese Classification of Mental Disorders and Hamilton Depression Rating Scale were used most frequently as diagnostic criteria and an assessment tool, respectively. Conduction exercise therapy was used in all studies; in contrast, Zheng Xing exercise therapy was used in only 1 study of depression patients with neck vertebrae disease. In 9 RCTs that showed scores of more than 2 points on a modified Jadad scale, tuina therapy had significant antidepressant efficacy compared with conventional treatment. However, more high-quality studies are required. Conclusions: Tuina therapy has a valid therapeutic effect on depression according to studies published in China; if evidence accumulates from high-quality studies, it can be considered a non-pharmacologic treatment for depression in Korean medicine, as well.

  • PURPOSE: This study researched the effects of different types of high heels on the muscles surrounding the cervical spine, the thoracic spine, and the lumbar spine by analyzing muscle activation of the paraspinal muscles during walking while wearing high heels. The high heels were all of the same height: 8cm. METHODS: The 28 subjects in this experiment were females in their 20s with a foot size of 225-230mm. To measure the muscle activation of the paraspinal muscles, EMG electrodes were attached on the paraspinal muscles around C6, T7, and L5. The muscle activation during walking while wearing 8cm high wedge heels, setback heels, and french heels was measured. The measurements were performed 3 times each and the mean value of the result was used for analysis. Two kinds of velocity were used in this study. One of the velocity was 2.5 m/s. The other was 3.5 m/s. RESULTS: The muscle activation of paraspinal muscles increased significantly according to increase of walking velocity. But there was no significant difference according to the heel types. CONCLUSION: In view of the results, the height of heels and the velocity of walking are more convincing variables than the width of the heels on the muscle activation of paraspinal muscles. So wearing high heels is not recommended for those who have pain or functional problem of cervical and lumbar vertebrae.
