This study started to examine the understanding and perception of 'disabled people' and 'non-disabled people', one of the dichotomous elements in the 21st century social integration era. In particular, for the analysis, Q-methodology, which should respond based on the respondent's inner self and perception, was used. For the analysis, 32 Q-statements were secured, and as a result of targeting 20 P-sample respondents, three types were derived as follows. In , statements such as 'A correct awareness of disability is necessary' and 'Disability can occur to anyone' are emphasized, so it was named 「Correct Perception Emphasis Type」. emphasized 'The life of the disabled is not easy' and 'The disabled need an opportunity to participate in society' and was named 「The Life of the Disabled Understanding Type」. emphasized statements such as 'Economic support is necessary for the disabled' and 'The welfare budget for the disabled must be sufficiently secured', and was named 「Institutional Support Emphasis Type」. Therefore, in addition to the necessity of correct recognition of disability and disability in our society, we expect this study result is to be priming water for improving the recognition of the disabled.

This paper first proposes diverse C determining models in the Q algorithm which is proposed in the EPCglobal C1 Gen 2 standard and then compares and analyzes its performance. EPCglobal C1 Gen 2 standard proposes the slot-count (Q) selection algorithm for multiple tag identification environment, but there is no such definition for the C value which modifies the Q value depending on collision or no reply. During the tag anti-collision process, the Q algorithm adds C to the Q when there is a collision and reduces the Q by C when there is no reply. The modified Q value updates new slot-counts for tags which determines the tag identification speed, so the C value is an important factor. However, many researches only intend to increase the tag identification speed by proposing a new method or modifying the Q algorithm without any research about the C value. This paper suggests diverse C models which satisfies the EPCglobal C1 Gen 2 and analyzes their performance in the multi tag identification environment. The result of this paper can be used as an index for future researches on EPCglobal C1 Gen 2 C models and multiple tag identification performance.

This study examined the static characteristics of a spool valve with a hybrid lap between the spool land and the sleeve. The static equation for the pressure characteristics was derived from flow equations that depend on the spool displacement, and the final model was derived from $q_a=q_b=0$ because the pressure characteristics test needs to block the control port in the valve. The static equation for the flow characteristics was derived from the pressure characteristics when the control port is open ($q_a=q_b$, $p_a=p_b$). The characteristic equation in the shifted region was assumed from the proportional relationship between the pressure-flow characteristics and the spool displacement.

The purpose of this study was to identify the types of subjectivity on communication styles of nursing freshmen and explore their properties by using the Q Methodology. Fifty nursing freshmen of P sample classified 55 Q-statements into the normal distribution of 11 point scale. Data were collected from May to June, 2015 and analyzed by using PC-QUANL program. As a result, communication styles are identified as 'Open-interaction facilitator', 'Other-considerate listener', 'Tense-sensitive to criticism person', and 'Non-interactive observer'. Open-interaction facilitators proficiently use verbal and nonverbal expressions, openly disclosing themselves and facilitating interactions with others. Other-considerate listeners primarily consider others before themselves, with careful communication. Tense-sensitive to criticism persons are nervous, sensitive to criticism, and are distractive style, so they have difficulties in intimate interaction with others. Non-interactive observers are bystanders who observe others and feel indifferent to interactions, without any self disclosure. The result of this study will be used for developing communication educational programs for nursing freshmen.

The development of direct receiver techniques is expected to be a solution for future wideband or multi-band wireless systems based on software defined radio. In this Paper, we study the regeneration of I and Q signals for the SDR based direct conversion receiver, so that we can handle a wide bandwidth and maintain maximal flexibility in system utilization. After modeling the basic system considering the real wireless communication environment, and studying the impact of imperfect phase imbalance on the performance of a direct conversion receiver, we propose a suboptimal I and Q signal regeneration algorithm for the system. The proposed algerian regenerates I and Q signals using a real time early-late compensator which effectively estimates phase imbalances and gives feedback in a directreceiver. The proposed algorithm is shown to mitigate the impact of AWGN and improves performance especially at low SNR channel condition. According to the computer simulation, the BER performance of the proposed system is at least about 4 dB better than conventional systems under $45{\~}55$ degrees random phase errors.

Until now, substring selectivities have been estimated by two steps. First step is to build up a count-suffix tree, which has statistical information about substrings, and second step is to estimate substring selectivity using it. However, it's actually impossible to build up a count-suffix tree from biological sequences because their lengths are too long. So, this paper proposes a novel data structure, count q-gram tree, consisting of fixed length substrings. The Count q-gram tree retains the exact counts of all substrings whose lengths are equal to or less than q and this tree is generated in 0(N) time and in site not subject to total length of all sequences, N. This paper also presents an estimation technique, k-MO. k-MO can choose overlapping length of splitted substrings from a query string, and this choice will affect accuracy of selectivity and query processing time. Experiments show k-MO can estimate very accurately.

This paper proposes a power management scheme for sensor nodes in wireless sensor networks based on sensor node operating system supporting the sensor transparency, which can turn off the sensors when the MCU is in sleep mode. We classify the sensors in two types, that is, event sensors and polling sensors, to be able to decide whether the sensor is a type of sensors whose power supply can be turned off or not, and we design a new scheduler to support recognition of those different types of sensors. Implementing and evaluation of the scheduler and the power manager supporting sensor transparency are shown based on Nano-Q+.

A novel blue-green emitting aluminum complex was developed by employing 8-hydroxyquinoline as co-ligand for enhancement of electron transport and light emission abilities so that the electroluminescent (EL) devices do not need additional electron transport layer. The aluminum complex (PAlQ) of 8-hydroxyquinoline and ${\alpha}$-pyridoin was synthesized The structure of the PAlQ was elucidated by FT-IR, UV-Vis and XPS. The PAlQ complex showed thermal stability up to 350$^{\circ}C$ under nitrogen flow by TGA. The photoluminescence (PL) was measured from solid film of the PAlQ complex on quartz substrate. The EL device was fabricated by the vacuum deposition. The device having the structure of ITO/TPD/PAlQ/Al was studied, where N,N-bis(3-methylphenyl}-N,N'-diphenyl-benzidine (TPD) was used as a hole transporting layer. The EL device emitted a blue-green light.
