Purpose : Carpal tunnel syndrome (CTS) is a disorder of median nerve at wrist. It is usually diagnosed through clinical manifestation and nerve conduction study (NCS). However, sometimes, NCS does not provide a reliable evidence to reach the diagnosis. Thus, authors performed this study to determine whether NCS was correlated with specific parameters measured on magnetic resonance imaging (MRI) which might become a potential complemental diagnostic tool. Methods : We performed MRI in 34 wrists of 18 patients with clinical manifestations of CTS and pathologic nerve conduction values and analyzed them at levels of the distal radioulnar joint, pisiform and hook of hamate, Results : Increase in the cross-sectional area of the median nerve at the pisiform level and flattening, increased signal intensity, and contrast enhancement of the median nerve at levels of the pisiform and hook of hamate were statistically significant. Change in cross sectional areas between the distal radioulnar joint and hamate and the signal intensities at levels of pisiform and hamate were well correlated with the median nerve conduction velocity. Conclusions : Characteristic MRI findings in CTS reported previously were well demonstrated and some of MRI parameters are well correlated with nerve conduction study. MRI, despite cost, may help in evaluating CTS.

The analysis of serum free light chains (sFLCs) can improve the diagnosis and monitoring of multiple myeloma and other plasma cell dyscrasias. As with other immunoassays, sFLCstests are subject to potential antigen excess and heterophilic antibody interference. We describe 9 cases of sFLCs antigen excess in patients with multiple myeloma using the FreeliteTM Human Kappa and Lambda Free Kits (The Binding Site ltd., Birmingham, UK) and the Hitachi7600 P module turbidimetric system. A total of 1,247 consecutive samples from 250 patients with multiple myeloma were assayed for sFLCs from April to September, 2009. The samples were assayed using an initial dilution of 1 :5and subsequent dilutions of 1 :50 and 1: 100. The same samples were analyzed for the presence of monoclonal gammopathies using serum protein electrophoresis (SPE) and immunofixation electrophoresis (IFE). There were 9 samples (0.72%) of antigen excess with 3 cases of kappa (0.24%) and 6 cases of lambda (0.48%). These cases represents an example of antigen excess or "hook effect" using the serum free light chain assays and mandates high level of attention to falsely low sFLC levels due to antigen excess, especially when it is disaccordant to other assay results or clinical manifestations.

Tough study of movement of Tae-Geuk-Guan(太極拳), we understand Tae-Geuk-Guan(太極拳) & essential movement. Theory about creator of Tae-Geuk-Guan(太極拳) is indistinct. there are Jangsampung-theory(張三豊設), Wangjongak-theory(王宗岳設), Jinwangjung-theory(陳王廷設), Jinbok-theory(陳卜設). Tae-Geuk-Guan(太極拳) is military arts developed before Song empire(宋). Tae-Geuk-Guan(太極拳) has many branch.(Jin-sik陳式, Yang-sik楊式, Mu-sik武式 O-sik吳式, Son-sik孫式) Tae-Geuk-Guan'(太極拳) manual movement use fist(拳), palm(掌), hook shape(鉤) and its using form has many type like Bung, Yi, Jae, An, Chae, Yul, Ju, Go. Its gait has many type like Sang-bo(上步), Tae-bo(退步), Jin-bo(進步), Deng-gak, Bun-gak(分脚), Bak-gak(拍脚). Essential theory of Tae-Geuk-Guan(太極拳) is Yi-Sim-Hang-Gi(以心行氣) & Yi-Gi-Un-Sin(以氣運身). It means mind(心) moves qi(氣) and qi(氣) moves body(身).

바리과(family Serranidae), 능성어아과(subfamily Epinephelinae)에 속하는 Epinephelus radiatus 1개체가 제주도 서귀포시 마라도 주변 해역에서 채집되었다. 본 종은 체측을 가로지르는 5개의 불규칙한 암갈색의 대각선 줄무늬와 측선비늘수 107개, 측선비늘공수 55개의 형태적 특징을 갖고 있다. 형태적으로 유사한 바리과 어류인 닻줄바리(E. poecilonotus)는 체측에 긴 수평 줄무늬를 가지는 반면, E. radiatus는 체측의 앞에서 뒤쪽으로 대각선 모양의 불규칙한 줄무늬를 가지고 있어서 쉽게 구분할 수 있다. 이 종의 새로운 국명은 우리나라 최남단 섬인 마라도 인근 해역에서 처음으로 채집되었기 때문에 "마라바리"로 명명하였다.

Excavators are construction machines used for digging soil, transporting soil, dismantling buildings and clearing the ground at construction sites. There are various attachments attached to the arm end of the excavator and used for various operations. There are the most common types of buckets attached for excavation and other types of attachments used for foresting, road cleaning, snow removal, and waste disposal. When multiple types of work are done at the same time, several attachments must be replaced and a device called a quick coupler is used to reduce replacement time. Although a quick coupler reduces the replacement time of the Attachment, it is necessary to attach safety devices to prevent unintentional detachment of attached attachments during the operation. To prevent the attachment from leaving or falling regardless of the operator's intention, support is installed in the hook of the bucket pin and controlled through a separate hydraulic cylinder to ensure safety. When attaching an attachment, it shall be attached without any action. This study is intended to verify the design validity of safety devices to prevent falls of attachments occurring at construction sites.

This is the first report of Snyderina yamanokami, from the subfamily Tetraroginae of the family Scorpaenidae, collected in Korea. The specimen (175.3 mm long) was caught in the coastal waters of Jeju Island on a commercial longline hook on 9 September 2009. This species is characterized by the following morphological traits: 9-11 dorsal fin rays, 5-6 anal fin rays, 13-15 pectoral fin rays, 5 ventral fin rays, pectoral fin tip reaching or extending past the origin of the anal fin, palatines toothless, and four dark spots on the middle of the body. We suggest a new Korean name, "Keun-mi-yeok-chi," for S. yamanokami.

The objective of this paper is to investigate the Intelligence control characteristics of a digital damper. This paper deals with a two-degree-of-freedom suspension using the damper with ER fluid for a quarter vehicle system. The control law for semi-active suspensions modeled in this study is developed using passive and ANFIS control method. Computer simulation results show that the semi-active suspension with ER damper has good performances of ride quality.

강릉시의 바닷가에서 채집한 서양갯냉이(Cakile edentula Hook.)를 국내 미기록 귀화식물로 보고한다. Cakile속은 국내에 처음 보고되는 속으로 십자화과에 속하며, 붓 모양의 열매가 2절로 나뉘는데 열매의 위쪽이 아래쪽보다 크고 엽병이 희고 화병이 없으며 잎에 털이 없다는 점에서 다른 속과 구분된다. 같은 Cakile 속이며 유럽 원산인 Cakile maritima는 꽃잎의 크기가 3~6 mm로 C. edentula보다 크고, 잎이 깃모양으로 깊게 파여 있다는 점에서 쉽게 구별할 수 있다. 2절로 나뉘어진 열매의 윗부분은 물이나 바람에 의해 산포되고 아랫부분은 모체에 붙어 있다.

Anglicae dahuricae Radix (ADR), the dried roots of Angelica Dahurica Benth et Hook (Umbelliferae), is a traditional herbal medicine used to treat colds, headache, skin diseases such as acne and possess analgesic, antipyretic and drainage effects. In the present study, the author evaluated the effect of ADR on regulation of inflammatory reaction. ADR reduced the ear-swelling responses derived from compound 48/80 in dose-dependent manner significantly. ADR inhibited the PMA plus A23187-induced productions of IL (Interleukin)-8, IL-1β, granulocyte macrophage-colony stimulating factor (GM-CSF) and tumor necrosis factor (TNF)-α from human mast cells (HMC)-1. In addition, ADR blocked PMA plus A23187-induced ERK1/2 phosphorylation. Ⅰ suggest that ADR regulates inflammatory reaction through inhibition of inflammatory cytokines such as IL-8, IL-1β and GM-CSF.
