The purpose of this study is to analyze the relationship between the credibility of soccer leaders in terms of the types of leadership and the achievement of the team. In order to do so. soccer players that currently registered with the Korea Football Association as of 2012 have been selected as the population group. 350 soccer players from five highschool soccer teams and five university soccer teams (a total of 314 final valid sample surveys) were chosen as study subjects. Such data were subject to frequency analysis, exploratory factor analysis, reliability analysis correlation analysis, and simple and multiple regression analysis. The conclusion obtained through the above study method and the results of analyzing the data are as follows. First, the sub factors in relation to leadership types that affected credibility were servant leadership and transformational leadership. Second, among the sub factors in relation to team achievement, the sub factor in relationship types that affected game results were servant leadership, transformational leadership and transactional leadership(-). The sub factors in relation to leadership types that affected game performance were transformational leadership and transactional leadership(-). The sub factors in relation to leadership types that affected the development of team work were servant leadership and transformational leadership. The sub factor in relation to leadership types that affected workout performance results was servant leadership. Third, credibility had a positive effect on all of the sub factors in relation to team achievement, game results, game performance, development of team work and workout performance results.

목 적: PCS 연구의 목적은 임상 방사선치료 QA의 표준 연구수단을 구축하고,방사선치료과 정의 기본요소를 결정하고, 협동 임상시험의 기반을 제공하고,외국과의 비교 연구를 위한 기본자료의 구축에 있다.우리나라 임상 방사선종양학의 PCS 연구기법으로서 구축한 웹 기반의 PCS시스템의 개발 및 특성을 보고하고자 한다. 대상 및 방법 : 본 시스템은 메인서버와 외부에 구축한 2중 백업서버로 구성되어 있다. 리눅스 운영 체제 및 MySQL 데이터베이스를 이용하여 프로그램을 완성하였다. PCS 대상이 되는 종양으로서의 개발 우선 순위는 1989년부터 1999년 사이에서 우리나라 전국의 방사선종양학과에서 치료빈도가 많은 순서를 근거로 결정하였다. 결 과: 2003년 초반에 웹 기반의 임상 PCS시스템이 구축되었다. 웹 주소는 www.pcs.re.kr이며, 우 선 유방암,직장암,식 도암, 후두암, 폐암 및 전이성 뇌종양을 대상으로 하였다. 완성된 개발 항목의 수는 1,000항목을 상회하였다.구축된 시스템은 사용자 편의성 충족, 기입 내용 중복 확인, 자료 기밀성, 자료 보존 및 사본 작성,이중 백업,통계 분석 지원 등 을 구현하였다. 문자화된 자료 외에 영상자료도 입력되도록 시스템을 구축하였다.아울러,임상시험승인 관련양식 지원, 무작위 자료 추출,방사선종양학과의 구조적 요소 파악 기능도 갖추었다. 결 론: 본 시스템은 PCS분야에서는 최초로 구축되고 작동되는 웹 기반 시스템이다.구축한 시스템을 통해서 단시간 내에 표본 자료의 수집이 가능하여 시간 및 비용을 절약할 수 있게 되었으나 구축자료의 신뢰도 확인을 별도의 검증과정은 필수적이다. 본 연구팀이 개발한 본 웹기반시스템은 향후 PCS 연구 또는 자료수집이 필요한 유사연구상황에 응용될 수 있는 표준적인 기법으로서의 활용되기를 희망한다. Purpose We report upon a web-based system for Patterns of Care Study (PCS) devised for Korean radiation oncology. This PCS was designed to establish standard tools for clinical quality assurance, to determine basic parameters for radiation oncology processes, to offer a solid system for cooperative clinical studies and a useful standard database for comparisons with other national databases. Materials and Methods: The system consisted of a main server with two back-ups in other locations. The program uses a Linux operating system and a MySQL database. Cancers with high frequencies in radiotherapy departments in Korea from 1998 to 1999 were chosen to have a developmental priority. Results: The web-based clinical PCS system for radiotherapy in www.pcs.re.kr was developed in early 2003 for cancers of the breast, rectum, esophagus, larynx and lung, and for brain metastasis. The total number of PCS study items exceeded one thousand. Our PCS system features user-friendliness, double entry checking, data security, encryption, hard disc mirroring, double back-up, and statistical analysis. Alphanumeric data can be input as well as image data. In addition, programs were constructed for IRB submission, random sampling of data, and departmental structure. Conclusion: For the first time in the field of PCS, we have developed a web-based system and associated working programs. With this system, we can gather sampled at a in a short period and thus save, cost, effort and time. Data audits should be performed to validate input data. We propose that this system should be considered as a standard method for PCS or similar types of data collection systems.
Macrophage의 IL-1β Gene Expression 대한 Lectin-conjugated Ellagitannin의 효과

Lectin-conjugated praecoxin A, which has developed as a missile antitumor drug, is the one that has conjugated with wheat germ agglutinin (WGA), a kind of carbohydrate- binding protein (lectin) especially bound to melanoma. Praecoxin A is a kind of tannin extracted and purified from plants. Beside this direct antitumor effect as tannins, we have examined an activation of macrophage by lectin-conjugated praecoxin A. We also confirmed the gene expression of IL-1β, both in vitro and in vivo. We added 1,10,100μg/ml of lectin-conjugated praecoxin A, 10μg/ml of pectin,10μg/ml of praecoxin A to normal murine macrophage and analyzed the extracted total RNAs by RT- PCR after 4,8, 12,24 hours. Our data demonstrated that pectin-conjugated praecoxin A increased IL-1β, mRNA expression in a dose dependent manner. However, the effectiveness of lectin-conjugated praecoxln A was not superior to pectin and praecoxin A.

An investigation is reported on the coating of ZnS:Cu,Cl phosphors by $HfO_2$ using atomic layer deposition method. Hafnium oxide films were prepared at the chamber temperature of $280^{\circ}C$ using $Hf[N(CH_3)_2]_4\;and\;O_2$ as precursors and reactant gas, respectively. XPS and ICP-MS analysis showed the surface composition of coated phosphor powder was hafnium oxide. In FE-SEM analysis, the surface morphology of uncoated phosphors became smoother and clearer as the number of ALD cycle increased from 900 to 1800. The photoluminescence intensity for coated phosphors showed $7.3{\sim}13.4%$ higher than that of uncoated. The effect means that the reactive surface is uniformly coated with stable hafnium oxide to reduce the dead surface layer without change of bulk properties and also its absorptance is almost negligible due to ultrathin(nano-scaled) films. The growth rate is about $1.1{\AA}/cycle$.

이 논문에서는 IS-95와 WCDMA의 Multi-mode로 동작하는 Multi-mode용 저전력 DDC filter 구조를 제안한다. 기존의 DDC구조의 경우 CIC의 통과대역 특성을 향상시켜 주지만, 저지대역의 감쇠특성은 오히려 나빠지는 문제점을 안고 있었다. 제안된 구조는 CIC 데시메이션 필터의 통과대역 특성은 더욱 향상시켜주며, 저지대역의 감쇠특성도 같이 향상시키는 특징을 가진다. 또한 제안된 필터는 각 필터의 면적을 감소시키기 위해 IS-95와 WCDMA의 각각의 모드에 대해 한 개의 필터를 설계한 후 각 모드에 따라 필터 탭 수를 달리하여 동작하는 Multi-mode의 저전력 구조를 구현하였다.
