  • There is hare and tortoise racing algorithm(HTA) for single-source(SS) singly linked list(SLL) with O(n) time complexity. But the fast method is unknown for general graph with multi-source, multi-destination, and multi-branch(MSMDMB). This paper suggests linear time cycle detection algorithm for given undirected and digraph with MSMDMB. The proposed method reduced the given graph G contained with unnecessary vertices(or nodes) to cycle into reduced graph G' with only necessary vertices(or nodes) to cycle based on the condition of cycle formation. For the reduced graph G', we can be find the cycle set C and cycle length λ using linear search within linear time. As a result of experiment data, the proposed algorithm can be obtained the cycle for whole data.

  • This paper is a result from validation study for SPDA(A Screening Scale For Potential Drug-use Adolescents) created in 2003 and newly developed during 2004. SPDA aims to screen adolescents in their early stage of drug-use and to help practitioners make a preventive approach for the adolescents. 4307 junior and senior high school students were selected as primary research subjects by stratified and quota sampling methods. 305 adolescents on probation were also selected as a comparison group and asked to answer the same questionnaire. Reliability for SPDA recorded 0.914, which proved to be better than previous year's (0.898). Exploratory and confirmatory factor analyses to test construct validity proved that SPDA could be divided into 7 factors and that each factor structure of SPDA could be a proper measurement model with high level of fitness and factor loadings. Discriminant analysis to test predictive validity confirmed that SPDA could classify the adolescents excellently by the frequency of drug-use, with hit ratio of 86.6 percent(78.8% and 87.4% for junior and senior high school students respectively). For concurrent validity test, Hare Home Self-Esteem Scale, Hare School Self-Esteem, Zuckerman-Kuhlman Sensation-seeking Scale were employed to find correlation with SPDA and all the three scales had significant Pearson correlation coefficients with SPDA. Known-groups validity test indicated that SPDA had an adequate power to classify out adolescents on probation from those in schooling, with a hit ratio of 71.8 percent. Cut-off point to detect adolescents with high risk of substance use was 77, which indicated approximately T score, 55 (0.5 SD), satisfying sensitivity, specificity, and efficiency criteria.

  • This study aims at monitoring the efficiency of wildlife corridor in the city of Sungnam, Gyunggi Province. During 2008-2010 for 13 months the CCTV in the city office followed number and population density using the wildlife corridor. Based on the monitoring Korean raccoon dog(Nyctereutes procyonoides) and water deer(Hydropotes inermis), Korean hare(Lepus coreanus), Korean yellow-weasel(Mustela sibirica), Korean squirrels(Sciurus vulgaris) used most often and counting 884 individuals.. This counts over 73% of targeted species and also verifies the project objectives. In future the monitoring should be increased and identify behavioral patterns focusing on ecological networks of previously fragmented habitats.

  • Autonomic dysreflexia is a clinical emergency syndrome of uncontrolled sympathetic output that can occur in patients who have a history of spinal cord injury. Despite its frequency in spinal cord injury patients, central nervous system complications are very rare. We report a man with traumatic high level incomplete spinal cord injury who suffered hypertensive right thalamic hemorrhage secondary to an episode of autonomic dysreflexia. Prompt recognition and removal of the triggering factor, the suprapubic catheter obstruction which led to hypertensive attack, the patient had a favorable functional outcome after the resorption of the hematoma and effective rehabilitation programme.

  • Pancoast tumor was specific lung carcinoma that has been symptoms and signs according to locations. It was located in peripheral,and involved the extrathoracic structures more than parenchyme of the lung. At 1838, Hare reported it, and at 1932 Pancoast was first described it. Prior to 1950,superior sulcus tumor was considered uniformly fatal, but at 1961 Paulson and Shaw advocated the use of preoperative irradiation therapy and followed by an extended en bloc resection. Recently we were experienced 2 cases of pancoast tumor managed with same method. One was 60-years old man that has been recommended preoperative radiation therapy with dose of 3000 cGy to 20 fractions and followed resection after 4 weeks, the other was 53-years old man that has been recommended a dose of 4000 cGy to 20 fractions and followed resection after 4 weeks. On tumor histology first case was large cell carcinoma and second case was squamous cell carcinoma. all patients was complicated atelectasis. First patient was expired with brain metastasis after 17 months, second was expired after 6 months.

  • This paper describes a new pwm scheme of variable speed control for induction motor. The proposed scheme have the programmed pwm switching pattern which have the doninant harmonic elimination over the wide range of output speed in induction motor. Experimental results of proposed scheme hare high quality output current, voltage and torque than that of conventional pwm scheme. Therefore proposed scheme have the smooth operation and suitable for variable speed control in induction motor.

  • The fiber morphologies of the textiles from the burials of the Seip group of Ohio Hopewell (ca. 100 B.C. to A.D. 500)mounds were examined using light and scanning electron microscopy. A theoretical model was proposed which delineates the rate of morphological change in fibers through time and the cultural activities which occur during the life of a textile element. The Seip textiles were categorized according to their visual and structural characteristics. The microscopic examination of the Seip textiles yielded the evidence of animal hair fibers and bast fibers. The animal hair fibers of the seip textiles were identified as the hair of rabbit or hare. The bast fibers of the Seip textiles exhibited variation in morphological features such as the degree of bundle separation and the presence of transverse striations, fibrillations, or trans-verse cracks.

  • Although the cosmetic market continuously develops in korea, the foreign product occupies more and more its market3hare in korea. For the future of our industry, institutional support for the ‘functional cosmetics’ (Cosmeceuticals) development should be secured and export infrastructure should be more solid. This paper examines recent trend in cosmetics market (home and foreign) and identifies barriers for the development of cosmetic market. In conclusion, we present several policy strategies for the development of its market.

  • Nitric oxide (NO) is a critical biological mediator involved in numerous diseases. However, the short lifetime of this molecule in biological conditions can make its study in situ complicated. Here, we review some recent results on the role of NO in angiogenesis, obtained using a biocompatible microelectrode array. This simple system allowed for the quick and easy quantification of NO released from cells grown directly on the surface of the sensor. We have used this technology to demonstrate that angiogenin induces NO release, and to partially elucidate its intracellular transduction pathway.

  • The Conservation Science Laboratory of the National Museum of Korea had drawn up the list of conservation treatment priority according to the artifact status in the collection and performed conservation treatment based on the priority list since 2006. This paper introduces the restoration process of the lost part of a black teacup(Sindo 1961) with newly developed restoration material. Part of the peeled off glaze was analyzed with LIBS and SEM-EDS analyser to find out the glaze ingredients that make the unique pattern of black teacup.
