Social network analysis is the social statistical analysis of any social structure involving a stream of mutual information between observations. In this study we used the results of passes between players in a soccer game. The analysis contents are as follows. (1) Players with important or leading roles are identified. (2) Players are assessed by pass frequency and the success rate of passes. The purpose of this study is for use as basic data for future team strategy, and achieves this by evaluating the role of each individual player within a team. In this study, social network analysis without separating positions is conducted, and is also performed for defensive and attacking positions respectively. The results of this study are as follows: First, when complete team data were available, the players performing leadership roles were Jung-woo Kim, Sung-yeung Ki and Chung-young Lee, whereas Jeong-su Lee acted as a sub-leader. In case of data for defensive positions Jeong-su Lee was a leading player, and in terms of attacking positions, all of the players excelled in the game and could be evaluated as playing lead roles.

인적 자원관리는 경영과정의 한 부분으로서 환경과 경영전략 그리고 조직구조와 밀접한 관계속에서 조직체의 목적 달성에 중요한 역할을 하고 있다. 특히 연구기관에서 인적자원은 가장 중요한 경영요소이며, "우수한 인력을 채용하여 능력에 맞는 수준 높은 대우를 함으로써 우수한 결과를 얻도록 하는 것"이 가장 기본적인 활동이다. 인적자원의 관리는 훌륭한 리더쉽에 의하여 실천되지만, 우선적으로 리더쉽을 수행할수 있는 제도적 시스템이 구축되어야 한다. 즉 인적자원 시스템을 형성하는 것은 효과적인 조직 성과를 달성하기 위한 제도적 장치를 마련하는 것이며, R'||'&'||'D 인적자원 관리 시스템은 연구목표 달성과 관련하여 개개인이 효과적으로 연구생산성을 제고할수 있도록 지원하여 주는 시스템이다. 조직성과에 영향을 주는 변수는 여러 가지가 있지만, 제도적 장치로 고려될 수 있는 것은 과업 및 조직의 설계, 인적자원 채용 및 배치 전환, 보상, 경력관리, 교육훈련, 능력 평가이다. 본 연구에서는 상기 인적자원의 성과를 높이기 위한 주요 변수(인적자원관리의 서브 과제)를 세계 주요 연구기관의 하나인 Battelle연구소를 대상으로 분석하고, 국내 R'||'&'||'D 인적자원관리 발전방향의 시사점을 제시하였다.

In this paper, we proposed A Study on Construction of Infrastructure for Handicapped Parking Areas Using RFID. This paper is Construction of the Handicapped Parking Areas infrastructure Using RFID with 900MHz band, and researched the optimal position of the tag attached on the vehicle and the location of RFID reader in order to raise the efficiency of RFID reader and the recognition rate by the handicapped vehicle. The result of research is shown the optimal position of RFID reader establishment when the height of RFID reader is 170cm in height and the angle of $80^{\circ}$ with the ground when the vehicle traveling direction of the antenna and the RFID reader when the surface and the angle of $90^{\circ}$ showed the best position RFID readers installed. Parking spaces for the disabled in accordance with these results the RFID readers installed and it works in conjunction with enforcement camera car tagged crackdown on vehicles and other general management, the system is built to allow handicapped parking spaces that meet the intent of the original purpose being used as expected to contribute significantly.

An orthogonal antenna is presented for reader application of radio frequency identification (RFID) at 433 MHz. Two 1x2 sub-arrays are orthogonally placed on a ground plane and two different feeding networks are applied to control horizontal and vertical radiation current flows for each sub-array, respectively. Inverted-F structures are used as radiation elements and can generate two linear polarizations by relative current distribution of radiators forming sub-arrays. Antenna gains are 2.7 and 0.4 dBi and isolation between two input ports is less than 25dB.

최근 사물인터넷(IoT)의 기반이 되는 아두이노 기술을 접목하여 다양한 스위치와 센서로 입력 값을 받아들여 LED, 모터와 같은 외부출력장치를 제어함으로써 상호 작용을 만들어 낼 수 있는 시스템개발이 유행이다. 본 논문에서는 아두이노를 이용하고 여러 가지 센서들을 활용하여 RC카 제작 및 거리제어 센서를 통한 DC모터 정지와 RFID를 통하여 LCD광고를 할 수 있는 자동차 시스템을 개발하였다. 개발한 시스템은 모터제어를 통하여 RC카의 전진과, 후진, 좌, 우 등 서브모터와, DC모터를 제어 하게 하였으며, 모터제어를 한 RC카에 블루투스 모듈을 장착하여 블루투스를 통하여 스마트폰으로 조종이 가능하도록 하였다. 안드로이드 어플을 사용하는 과정 중에 멈춤 오류로 인하여 S값을 한번만주는 형식의 안드로이드 어플을 이클립스로 제작하여 수정하였으며 전방에 거리감지센서를 장착하여 자동차의 20~150cm앞에 물체가 있을시 모터를 정지하게 하여 속도를 제어 하도록 하였다. 또한 RFID리더기를 사용하여 태그키가 RFID리더기에 태그 될시 LCD화면에 광고를 노출할 수 있게 하였다.

Using the radio wave, RFID(: Radio Frequency IDentification) wirelessly transmits the unique information saved in a tag attached on the specific object. In the construction area, the trend in using RFID for managing the input and inventory of the construction materials is upward. General management systems for the construction materials have only a function of identifying the tag attached on the construction materials, but the management system with a function of identifying and managing the location information of the construction materials employing RFID, for reusing it, is not actively developed. For the efficient reuse of the construction materials, in this paper, we propose the RFID system with a function of estimating and saving the location information of the specific construction materials, based on the estimated distances between the particular subs and reader. The proposed system consists of RFID reader, distance estimate, communication, and memory units.

In this paper, we propose a novel hybrid reader antenna using a triangular and rectangular sub-patch for near- and far-field RFID reader in UHF band. The antenna operates at 912 MHz, and the low-cost mass-production is available, since the antenna can be built by printing on a FR-4 substrate. The triangular patch is designed to produce a circularly polarized radiation along the bore-sight direction and the rectangular sub-patch is designed to generate a strong magnetic field over the antenna aperture. The measurement shows Hz field greater than -25 dBA/m(3 cm above the antenna aperture), and exhibits circularly polarized radiation(AR<3 dB) with a radiation gain of 6 dBi.

This study was to suggest display of RDA resource type in OPAC efficiently. Literature reviews and users test and preference survey were used as research methods. The 4 ways for the display of RDA resource type were suggested. First, GMD and the resource type code(bcode2) invented by library itself as well as leader/06, 007, and 008 field should be used for converting AACR2 resource type to RDA resource type in the bibliographic records. Second, RDA resource type vocabularies applicable to Korean cataloging environment should be designed and described in 33X subfield ${\blacktriangledown}9$ and detailed resource terms described in 34X should be also expressed in OPAC. Third, two option is suggested as content type and carrier type display separately and as content type and carrier type combination. Fourth, 336, 338 filed, leader/07 bibliographic level, 008/30-31 Literary text for sound recordings, 34X field were useful to develop user centered resource type icon. This study would be able to increase the utilization of RDA resource types and help the users to understand the RDA resource type in OPAC.
