  • Recently in the human society, the crime using small arms has increased. Also, many accidents happen because of incomplete management of chemicals and radiation. Accordingly, it is necessary to manage dangerous objects by tracing the position of dangerous objects and rapidly providing the correct information for them. This paper presents a web-based system for real-time monitoring of dangerous objects using RFID in order to overcome the limitations and problems of current dangerous objects management techniques. In this paper, we define the architecture for web-based dangerous objects monitoring system and the scheme for storing information of a dangerous object in the RFID tag. We also implement the web-based monitoring system and present the execution result of the system. The proposed real-time monitoring system is composed of the dangerous objects monitoring server which manages information of dangerous objects and controls them, the dangerous objects monitoring middleware which is mediator between dangerous objects and the server, the RFID reader which reads information of dangerous objects from RFID tags attached to the objects and the database which stores information, status and position of dangerous object. The proposed system manages diverse dangerous objects such as small arms, radiation and harmful chemicals based on the position of them using RFID, so the user can check dangerous objects when they are checked in and checked out and the user can acquire the real-time position information of them through the system. Furthermore, the user can visually monitor dangerous objects through web browser from any where and at any time because the system is web-based system and it provides graphical user interface.

  • Aims: To investigate the distribution of epidermal growth factor receptor (EGFR) mutations, and explore any relationships with clinical characteristics in non-small-cell lung carcinoma (NSCLC) patients. Materials and Methods: EGFR mutations were assessed by ADx-ARMS in 261 NSCLC patients from West China Hospital of Sichuan University. Relationships between EGFR mutation and clinical characteristics were analyzed by SPSS. Results: The EGFR mutation rate was 48.7% (127/261), 19-del and L858R mutations occurred predominantly, accounting for 33.1% and 40.9%, respectively, in mutated cases. Moreover, 10.2% patients were found to carry double mutations. EGFR mutations occurred more frequently in women (57.5%) than in men (41.8%) (P=0.01), and were more frequent in non-smokers (61.2%) than in former or current smokers (31.2%) (P<0.00). In addition, they were more common in adenocarcinomas (52.8%) and adenosquamous carcinomas (42.8%) than in squamous cell carcinomas (14.8%) (p<0.00). However, only smoking history and pathological types, rather than gender, proved to be associated with EGFR mutations on multivariate logistic regression analysis. No significant differences in pathological stage and metastasis status were found between EGFR wild-type and mutated cases, although EGFR mutation type was related to pathological type (p=0.00) - 19-del, L858R and other mutation types respectively occurred in 34.2%, 42.5% and 23.3% of adenocarcinomas, but in 14.3%, 0% and 85.7% of non-adenocarcinomas. Conclusions: The EGFR mutation rate was 48.7% in NSCLCs in Southwest China, so that nearly 40% patients might benefit from targeted therapies. Smoking status and pathological types were independent predictors of EGFR mutation, while EGFR mutation type was related to only pathological type, rather than smoking status.

  • In this paper, we propose an FSSH(Folded Slot Spherical Helix) magnetic dipole antenna with a form factor easy to build and study its radiation properties. The number of folded arms, the gap between them and the metal thickness are tuned to achieve relatively simple structure to realize whereas maintaining high radiation efficiency at an electrically small size. The proposed design shows wide radiation efficiency bandwidth and it is confirmed by circuit simulation that the non-Foster impedance matching techniques could be utilized for its practical use. The prototype of the proposed antenna is built with the aid of an SLS(Selective Laser Sintering) 3D printing technology. The measured result shows lower Q impedance characteristic due to high resistive loss of the copper tape joints.

  • Forty specimens of fossil ophiuroids were collected from two formations of the Cenozoic marine deposits, Duho Formation and Hagjeon Formation, Pohang Basin, Korea. A few specimens were three-dimensionally preserved: most of them were remained flattened and articulated. Although a gross morphology is well preserved in some specimens, the details such as disk shape and plates which is the most important diagnostic features were not observed. Most of the arms are disarticulated, and thus arm vertebra, arm spines and/or arm plates are separately preserved. Only an oral side is recognized in an attached specimens because crossing arms into disk are clearly visible. It is, thus almost impossible to identify Korean ophiuroid fossils as a species level or even a genus level. The fossils were classified into 3 groups by gross morphology of disk and arm, and architecture of vertebra. The most abundant fossils (32 specimens), were found only in the Hagjeon Formation. The majority of specimens are partially disarticulated, having only proximal and median portions of their arms preserved. Arm plates are disarticulated from arm vertebra: most of them show structure of arm vertebra. It has long and well-preserved arm spines, and large tentacle pore. Some specimens (4 specimens) from the Duho Formation is characterized by short and conical arm spines, and well-developed arm plates. Lateral arm plates are small in compared to dorsal and ventral arm plates. The others (4 specimens) is poor in preservation state showing circular oral disk and relatively short sinuous arms. No arm plates are either identified.

  • Platyspondylic lethal skeletal dysplasia, Torrance type (PLSD-T), is one of the pheno-types of type II collagenopathy and is characteristic of severe bone growth disorder. This phenotype may limit the growth and expansion of the lungs, which is known to cause death from respiratory failure during or shortly after birth, but in few less severe cases, patients have been reported to have survived to adulthood. We have experienced a case of PLSD-T in a preterm infant who was delivered via cesarean section at the gestational age of 29 weeks 3 days, with a birth weight of 1.15 kg. Physical examination of the infant revealed characteristic findings of short arms and legs, small thorax, distended abdomen, and cleft palate. On the basis of the subsequent genetic testing, the patient had a heterozygous mutation in the encoded c-propeptide region of collagen, type II, alpha 1 (COL2A1), c.4335G>A ($p.Trp1445^{\ast}$) in exon 52. This is the first case of PLSD-T diagnosed in Korea, and we hereby report the case.

  • Recently, we have been able to quickly order and pay with kiosks even at fast food restaurants, small private restaurants and cafes. However, people with disabilities who are uncomfortable with their arms and who are sitting in wheelchairs are difficult to use by pressing graphical buttons to use kiosks. Older people also feel uncomfortable to use kiosks because of their cognitive abilities to accept new information as they get older. In this paper, to solve this problem, we design and implement a order-payment system to add the voice command element of the AI speaker to the visual command element when the user interacts with the kiosk.

  • This paper is launched to get an exact bore-sighting value in the process of assembling for a dual-barrel weapon. Image processing method with a CCD(Charged Coupled Device) camera is chosen for the error reduction of bore-sighting. The results of this method by using a CCD camera and the testing target method are described in this paper. After the performance of the dual-barrel weapon and that of the fire-control system in the dual barrel weapon system is confirmed, the bore-sighting which is a part of the process in the system assembly is accomplished. In this process, the position of the barrel is identified by using the testing target method that is an existing bore-sighting method. Then, the fixing line of the fire-control system is checked by a day-optical part. The precision of the bore-sighting is required within several mils, however the manual method using the naked eyes makes it worse. Therefore, a CCD camera is installed in the eyepieces. Next, we can get an image of the sighting and the center coordinate values of the laser-pointer from each barrel by image processing method. A required bore-sighting value is calculated from the eccentricity of the center coordinate. Finally, It can be applied to adopt this result in the assembling process of the dual-barrel weapon.

  • As industrial technology was developed, necessity for small size motor was increased on various fields such as medical treatment and robotics. The motor should be simple structure, and it has easy process of manufacture to overcome the limit of miniaturization. So, "the windmill type ultrasonic motor" is enough to satisfy these conditions. In this paper, windmill type ultrasonic motor which was proposed by B.Koc and K.Uchino, was analyzed and fabricated with modified endcap shape. Displacements of arms of the proposed endcap were compared with the previous endcap, using the finite element analysis program (ANSYS). Better rotational characteristics was expected in proposed model as result of FEA. Experimentally, rotary motors of 3.5 [cm] diameter were fabricated, and the speed and torque of the motor were measured. As a result, speed and torque were changed in proportion to the electrical input voltages. And low efficiency which was different from an expectation was obtained in this motor. So, various problems should be improved for practical use.

  • Recently the number of women's hospitals of a small scale are increasing in seoul and the other cities although the surroundings of these sites are so inferior. Those hospitals need the space of comfort as like family home. This study suggests that the encirclement space is one of the design methods to make comfort to patients. The encirclement is the form of hugging a baby to a mother's arms. Analysing six woman hospitals, encirclement space is categorized about the six types of square, open square, right-angled, linear, dispersed, etc. The characteristics of "right-angled" is featured as the form of L, and "square" type is characterized as the relationship of functional circulation among doctors, nurses and patients. And all types are organized as the relationship between the encirclement space and the enclosed space about how the functional space and the comfort space are made up. The properties of encirclement space are appeared by the interactions about function, circulation, sight, form, access, recognition through transparent, three-dimensional experience, etc. Encirclement space is recommended as a vital factor to make comfort space for designing women's hospital in city.
