  • The establishment of an effective bidding system is critical to ensure both the high quality of civil infrastructure and proper earning of contractors. However, the continuous changes of a bidding system in South Korea reveal that problems such as a dumping or high price winning have not been fully resolved yet. This study thus aims at understanding the bidding behavior and strategies of contractors by analyzing a tender ratio in historical data. Multiple regression analysis is conducted to understand the effect of internal and external factors (e.g., estimated cost, combined value of construction performance evaluation) on a tender ratio. The results statistically show that such factors affect the tender ratio an individual bidder determines and have the varying effect on the tender ratio by contractors' firm size.

  • More a reddish color of KNBP was related to higher frequency of slower fiber type. Tender meat with a faster ageing rate for KNBP was coincided with a faster proteolytic rate, and likely a higher collagen solubility (data not shown). However, it is not confirmed whether the results were linked to the favorable pH/temperature window during rigor development, or fiber composition for tender meat.

  • This study was conducted to seek optimum sowing time and pinching height for tender shoots production of moloheiya (Corchorus olitorius L.), which is a subtropical leaf vegetables, under an unheated greenhouse in the south of Korea. Seeds of moloheiya did not germinate at all at $10^{\circ}C$, but germinated well at $18{\sim}30^{\circ}C$ with 95.5~98.5% germination rate. Germination rate was 75.0% at $15^{\circ}C$, but germination speed was very low. The pods of moloheiya sown before April 28 was matured after late-August, but those sown after May 7 was not matured in that year. In tender shoot production and harvest frequency, treatment sown on April 14 was most plentiful among sowing time treatments, and showed marketable yield increase by 14~42% compared to other sowing times. Mean-while, pinching at 100cm high from soil surface was more effective than other heights for increment of branches and tender shoot. All above suggest that it was suitable to sow seed on mid-April and to pinch at 100cm high from soil surface for increment of tender shoots in the south of Korea.

  • The purpose of this study was to investigate the peak electromyographic activity(EMG) and time intervals in firing sequence of Anterior temporalis(TA) and Masseter(MM) on clenching, the number of tender points in the head and neck muscles, the occlusal contact state on clenching, and their relationship. 78 patients with Temporomandibular Disorders(TMDs) participated and were classified into articular or muscular group by clinical signs and symptoms. BioEMG$\textregistered$ of integrated masticatory function analyzer, Biopak$\textregistered$ system(Bioresearch Inc., USA), was used to measure EMG and related items, and T- Scan$\textregistered$(Tekscan, USA), computerized occlusal analyser, was used to record occlusal contact state on maximum voluntary clenching. EMG and occlusal contact were synchronously recorded and analysed with SAS Statistical program. The results of this study were as follows : 1. In total subjects, EMG of TA was lower than that of MM in articular group but in muscular group, vice versa, As a result, the ratio TA to MM was significantly different between the two groups. no significant differece. 3. The number and force of occlusal contact were more in articular group, but there was no significant difference in Total Left-Right statistics(TLR) between the two groups. 4. In unilaterally affected subjects for muscle function, no significant difference was observed between the affected side and the contralateral side in articular group, but in muscular group, the item of the number of tender points showed significant difference. However, for occlusal contact items, contact force in articular group shows significant difference between the two sides. 5. Rate of coincidence of the first firing side of TA with affected side or preferred chewing side was higher and not different between the two groups, but no significant correlation was showed between the first firing side and the first occlusal contact side.

  • Tarsal tunnel syndrome is defined as a compressive neuropathy of the posterior tibial nerve in the tarsal canal. Schwannoma is a benign tumor that arises from the peripheral nerve sheath. It presents as a discrete, often tender, and palpable nodule associated with neurogenic pain or paresthesia when compressed or traumatized. The growth rate is usually slow, and these lesions seldom exceed 2 cm in diameter. In addition, local recurrence occurs less than 5%. We report on a case of tarsal tunnel syndrome caused by a large recurred space-occupying lesion measuring $4.3{\times}2.7{\times}2.7cm^3$.

  • Histiocytic necrotizing lymphadenitis(NHL), or Kikuchi-Fujimoto disease, is of unknown origin that causes persistently enlarged cervical lymph nodes unresponsive to antibiotic therapy, usually in young women. Symptoms of NHL include tender cervical adenopathy, fever, weight loss, and night sweats. Laboratory studies usually reveal leukopenia and increased erythrocyte sedimentation rate. Lymph node biopsy reveals areas with frank cell necrosis, karyorrhexis, and absence of plasma cells. NHL follows a benign course, but shoud be differentiated from other diseases such as inflammatory, granulmomatous and malignant lymphadenopathies. We describe . three cases of NHL with a review of the literature.

  • The inluence of styrofoam-panel thickness of floating frame on the seedling growth of flue-cured tobacco(Nicotiana tabacum L.) in the newly developed direct-seed float system was investigated . Floating frame used instead of styrofoam-tray consisted of styrofoam-panel (106×108cm) for floating, eight holes(1.Sx2S.0 cm) to uniform the water, and nutrition supply far seedling and water and nutrition absorption cloth placed on the styrofoam-panel. Each floating-frame may lay eight plastic-trays on it. Eight grades of styrofoam-panel thickness from 26 mm to 46mm and two kinds of media were used in the greenhouse system. Dry cells were found from the styrofoam-panel thickness of 43mm in carbonized chaff, compost and original soil rate of L3-3(v/v) media, and of 37mm in peat and perlite rate of 8-2(v/v) media. The thinner styrofoam-panel produced more tender and succulent seedling with the more trunk and the less root weight. When considering the appearance of dry cell, seedling growth, producing healthy tobacco seedlings, and utilization of styrofoam-panel for two kinds of medias the ideal styrofoam-panel thickness were suggested to be around 34mm for flue-cured tobacco reeling production in the newly developed direct-seeding float system. Key words : tobacco seedlings, float system, medium, styrofoam pannel, dry cell.

  • The government intensifies screening criteria for the guarantee of reasonable bidding price and the prevention of low bidding price, however, the low tender rate still becomes an issue. This study analyzed the problems of screening criteria for the guarantee of reasonable bidding price, and then derived some major issues such as the restriction of decisive factors for initial construction cost, the rate of activities over five percent of surveyed price and the restrictive review criteria of inadequate activities. To solve thess problems, this study suggests an improved process model for estimating optimal bidding rate that can select a contractor with the guarantee of reasonable bidding price.

  • Cavernous hemangiomas, one of common hemangiomas, are collections of dilated vessels deep in the dermis and subcutaneous tissue that are present at birth. Clinically they appear as pale, skin-colored, red, or blue masses that are ill defined and rounded. Like strawberry hemangiomas, the lesions enlarge for several months, become stationary for an indefinite period, and undergo spontaneous resolution. Usually, they are managed like strawberry hemangiomas, for example, compression, take corticosteroids or interferon and use lasers(pulsed dye lasers and argon lasers). It is similar to 血瘤 and 紅絲瘤 in Oriental Medicine. We observed and treated a 8 month old male infant who had been diagnosed with cavernous hemangiomas on near medial side of the right transverse cubital crease. He had been treated by lasers three times each month about 2 months after the on set of disease in another College of Medicine Hospital. However, his sign didn't any change. He first visited our clinic about 7 months after the on set of disease. bout 1 year after our treatment, herb-medication and acupuncture treatment, the volume of hemangiomas was decreased remarkably and the colour was lighter. It was tender to the touch more and more. It is very rate that someone has cavernous hemangiomas and visits Oriental Medicine Hospital. Also we don't have much the treatment experience of this disease. I expect this case will be one of the base of treatment and management on this kind of diseases.
