Thoracic outlet syndrome's chief symptom has numbness and tingling sensation of tharm, hand and fingers. In the morning, patient complain of pins and needles of the hands and weakness. TOS classified three categories : Anterior scalene syndrome, Claviculocostal syndrome, Pectoralis minor syndrome Physical therapy of the TOS is heat, massage for soft tissue, stretching exercise for scalene muscles and pectoralis minor muscles, and strengthening exercise for upper trapezius and levator scapular and neck muscles. A main problem of soft tissue is mechanical causes, so physical therapists have to solve that problem by mechanical manual methods.

This paper proposes free warranty interval for repairable items when the failure types of item are considered. Failure types are classified into major failure and minor failure. If major failure occurs during warranty period, the item is replaced and if minor failure occurs during warranty period, the item is minimally repaired. This paper determines the optimum free warranty interval which minimizes total expected cost of the free warranty cost model. Numerical example is shown in which failure time of item has weibull distribution.

In Sjogren syndrome, abruptly decreased salivation and delayed lag time reveal that many acini cells are destructed and Lymphocytes infiltration is supposed as the main cause that makes dysfunction of salivation. In this case report, the biopsy of minor salivary glands is very useful diagnostic method of Sjogren's syndrome with sialometry,sialography, salivary gland scan.

From the bulbs of Erythronium japonicum Decaisne(Liliaceae), ${\beta}-sitosterol$ and its $3-O-{\beta}-D-glucoside$ together with fatty acids were isolated. All compounds were identified on the basis of spectral data. Campesterol and stigmasterol were also identified as minor components. Paimitic acid was identified as a major component and stearic, oleic, arachidic, behenic, tricosanoic and lignoceric acids were also characterized as minor ones.

Photoreaction of 8-methoxypsoralen (8-MOP) with thymine (${\ge}$ 300 nm) was carried out in the dioxane-water frozen state. One major and two minor monoaddition products between 8-MOP and thymine were isolated by various chromatographic methods. Major monoadduct was characterized to be a C4 cycloaddition product formed between 5,6-double bond of thymine and 3,4-double bond of 8-MOP with cis-anti stereochemistry. Two minor adducts were proved to be stereoisomers of this major adduct.

Arenealdehyde 2-benzothiazolylhydrazone in thianthrene cation radicalafforded triazolo[3,4-b]benzothiazoles and 1,2,4-triazoles as major and minor product, respectively. On the contrary the similar reaction in tris(2,4-dibromophenyl)aminium hexachloroantimonate gave 1,2,4-triazoles and triazolo[3,4-b]benzothiazoles as ma-jor and minor product, respectively.

Necrotizing sialometaplasia is a rare, benign, self-limiting inflammatory process, with most cases occurring in the palatal region. Although the pathophysiology of this condition remains unknown, it has generally been considered an ischemic reaction involving the minor salivary glands. Due to its clinical and histologic similarities to malignant salivary gland tumor, diagnostic biopsy is required. Careful monitoring is also recommended, and clinicians should provide sufficient information for pathologists to ensure the histologic diagnosis.

Purpose: To evaluate interpretation errors involving spine MRIs by residents in their second to fourth year of training, classified as minor, intermediate and major discrepancies, as well as the types of commonly discordant lesions with or without clinical significance. Materials and Methods: A staff radiologist evaluated both preliminary and final reports of 582 spine MRIs performed in the emergency room from March 2011 to February 2013, involving (1) the incidence of report discrepancy, classified as minor if there was sufficient description of the main MR findings without ancillary or incidental lesions not influencing the main diagnosis, treatment, or patients' clinical course; intermediate if the correct diagnosis was made with insufficient or inadequate explanation, potentially influencing treatment or clinical course; and major if the discrepancy affected the main diagnosis; and (2) the common causes of discrepancy. We analyzed the differences in the incidence of discrepancy with respect to the training years of residents, age and sex of patients. Results: Interpretation discrepancy occurred in 229 of the 582 cases (229/582, 39.3%), including 146 minor (146/582, 25.1%), 40 intermediate (40/582, 6.9%), and 43 major cases (43/582, 7.4%). The common causes of major discrepancy were: over-diagnosis of fracture (n = 10), missed cord lesion (n = 9), missed signal abnormalities associated with diffuse marrow (n = 5), and failure to provide differential diagnosis of focal abnormal marrow signal intensity (n = 5). No significant difference was found in the incidence of minor, intermediate, and major discrepancies according to the levels of residency, patients' age or sex. Conclusion: A 7.4% rate of major discrepancies was found in preliminary reporting of emergency MRIs of spine interpreted by radiology residents, probably related to a relative lack of clinical experience, indicating the need for additional training, especially involving spine trauma, spinal cord and bone marrow lesions.

본 연구는 통영연안의 오염 현황을 파악하기 위하여 표층퇴적물의 유기물 분포 특성, 미량금속의 공간적인 분포 특성과 오염도 및 생태계 위해성평가를 하였다. 총질소(Total nitrogen, TN), 총유기탄소(Total organic carbon, TOC)와 산 휘발성 황화물(Acid volatile sulfide, AVS)은 협수로에 위치한 정점 35-38에서 높은 농도를 나타내었다. Cd, Cr, Ni, Co, Hg, Zn의 공간적 분포양상은 유사하였으며, 이와 달리 Cu는 협수로에서 높은 농도를 나타내었다. 미량금속 원소의 오염도를 농축계수(Enrichment Factor, EF)로 평가한 결과, Cd이 모든 정점에서 오염되지 않은 상태(No enrichment), Pb, Cr, Ni, Co, Zn, Hg이 약간 오염상태(Minor enrichment), Cu가 약간~중간 오염상태(minor-moderate enrichment)의 오염도를 나타냈다. 미량금속에 의한 생태위해성 수준은 오비도와 미륵도 사이의 협수로 정점에서 국지적으로 생태계에 잠재적 위해성이 있는 것으로 나타났다.

Red ginseng possibly has new ingredients converted during steaming and dry process from fresh ginseng. Kujeungkupo method which means 9 repetitive steamings and dryings process was used for the production of red ginseng from 6-year old ginseng roots. Saponin was extracted from each red ginseng produced at the 1st, 3rd, 5th, 7th, and 9th during the steaming and drying treatment, and we analyzed saponin content with TLC. Minor saponins, such as ginsenoside-Rg3, -Rh2, compound K, and F2, increased as the process time of steaming and drying, but major saponins (ginsenoside-Rb1, -Rb2, -Rc, -Rd, -Re, -Rf, -Rg1) were decreased. Major saponins were yet observed almost at the 1st process, then degraded as the increasing time of steaming and drying process. Especially, ginsenoside-Re and -Rg were observed as considerable amount after the 1st treatment, but there were no trace of them after the 9th treatment. Ginsenoside-Rg1, -Rb2, and -Rb1 were also reduced remarkedly by 96.6%, 96%, and 92.3%, respectively. Minor saponins were increased significantly, especially for ginsenoside-Rg3 and ginsenoside-F2. These results suggest that Kujeungkupo method is the very useful method for the production of minor ginsenoside-Rg3 and -Rh2.
