The study was performed to investigate the distributions of swine pleuropneumonia in Kyongbuk western area by the enzyme-linked immunosorbent assay (ELISA). Sera collected from 400 slaughtered pigs in 3 slaughter houses during the period from May 1999 to october 1999 were tested to detect antibodies against A pleuropneumoniae serotype 2 and 5. The optimal dilution of CBE antigen, conjugate and serum for this ELISA were determined 1: 400, 1: 20,000, 1: 100, respectively. The optimal dilution of O]VIP antigen, conjugate and serum for this ELISA were determined 1: 100, 1: 20,000, 1: 200, respectively. Cut-off value in this ELISA was determined by mean absorbance (at 492 na) of negative control sera added with the triple value of the standard deviation. Cut-off value in ELISA by CBE and OMP antigen were 1.134 and 1.217, respectively. By the ELISA, positive reaction rates to A pleuropneumoniae serotype 2 and 5 for CBE antigen were 38.8% and 18.8%, and for OMP antigen were 42.8% and 23.5% of the 400 samples, respectively.

이 연구에서 우리는 3차원 계층적 나노구조화된 유/무기 복합 표면을 가진 소수성 코팅/필름을 제조하는 방법을 제안한다. 먼저 근접장 나노패터닝(PnP)이라 불리는 첨단 포토리소그래피 기술을 통해 에폭시 기반의 대면적 3차원 정렬 나노다공성 템플릿을 준비하였다. 이후, 딥 코팅을 통해 평균 직경이 22 nm인 실리카 나노입자를 템플릿에 조밀하게 함침시켜 계층적 구조화된 표면을 구현하였다. 표면에 공존하는 마이크로 및 나노 스케일 거칠기로 인해, 제조된 복합 필름은 대조군에 비해 물에 대한 높은 접촉각(>137도)을 나타내었다. 따라서 본 연구를 통해 개발된 소재 및 공정은 전통적인 코팅/필름 분야에서 다양하게 활용될 수 있을 것으로 기대된다. In this study, we propose a method for fabricating hydrophobic coatings/films with three-dimensional (3D) hierarchical nanostructured organic/inorganic composite surfaces. An epoxy-based, large-area 3D ordered nanoporous template is first prepared through an advanced photolithography technique called Proximity-field nanoPatterning (PnP). Then, a hierarchically structured surface is generated by densely impregnating the template with silica nanoparticles with an average diameter of 22 nm through dip coating. Due to the coexisting micro- and nano-scale roughness on the surface, the fabricated composite film exhibits a higher contact angle (>137 degrees) for water droplets compared to the reference samples. Therefore, it is expected that the materials and processes developed through this study can be used in various ways in the traditional coating/film field.

본 논문에서는 다중 입출력 안테나 OFDM 통신시스템에서 가상 기준 신호(virtual pilot signal)를 사용하는 한 연판정 지향 채널 추정 기법을 제안한다. 기준 신호만을 이용하여 채널을 추정하는 기존 방식과 달리 제안하는 기법은 기준신호와 데이터를 동시에 사용하여 채널을 추정한다. 또한, 제안하는 기법에서 채널을 추정하기 위해 사용할 데이터를 선택하는 알고리즘을 제안한다. 모의실험을 통해 제안하는 기법이 기존 채널 추정에 비해 향상된 성능을 갖는 것을 확인할 수 있다. In this paper, we proposed a soft decision-directed channel estimation based on MMSE estimation for MIMO-OFDM system. While the conventional method employs only pilot signals for channel estimation, the proposed algorithm performs channel estimation using pilot and reliable data signals. We also proposed selection criterion among reliable data signal for channel estimation. From numerical simulations, we show that the proposed channel estimator achieves 1 dB performance gain over conventional channel estimators.

The purpose of this study is to analyze subjective thinking of student pertaining to adjusting to student life by applying the Q methodology. Students currently enrolled at an Sports related departments were chosen as subjects of study. For the study of the study, with first year students currently enrolled at K University in C city in Chungcheongbukdo for school year 2009, Q methodology was applied and an interview was conducted with each subject. A total of 120 answers collected on positive and negative aspects of adjusting to their department and based on them, a questionnaire of 25 Q statements were extracted. For the 25 final statements, the respondent were asked to use a 9 point scale, a Q sorting was applied for forced distribution and the results were analyzed through factor analysis using the QUANL 1.2 program. Characteristics of each type are as follows. Type 1 (N=13; Exercise directed type) was termed "Exercise Directed Type) of adjusting with the purpose of prioritizing exercises between peers, upper classmen, and lower classmen in the school adjusting process of department students. This type includes environmental conditions that make free exercise possible, formation of bonding and friendship between upper classmen and lower classmen, and participation in on sit oriented outdoor classes through sports club activities and sports club contests and it is a type that geared for a higher level of departmental activities. Type 2 (N=3 Positive organization directed type) was termed "Positive Organization Directed Type" of adjusting with the purpose of prioritizing peer relationship among peers and hierarchical structure among upper classmen and lower classmen in the process of adjusting to school life in students in the department. This type viewed the tight bond between peers, clear hierarchical relationship between upper classmen and lower classmen, structured hierarchical system, advice and interest of upperclassmen in others, financial assistance through the department as positive factors. Type 3 (N=17, Relationship directed type) was termed "Relationship Directed Type" with the purpose of forming a relationship between upper classmen, lower classmen, and pear, to enhance familiarity, and a strong bond. Positive aspects in adjusting to school life in the departments are types that include formation of environment that allows free exercise, building of bond and friendship between upper classmen and lower classmen through sports club activities, a hierarchical system with clear and structured relationship between upper and lower classmen, strong bond between peers, and unity among upper and lower classmen. The Q statements that were formed from all three types deduced from this study were extracted with 11 questions. In adjusting to their department, strong bond among peers was viewed as most positive aspect and viewed one sided orders or statements as most negative aspect.

스포츠 부정부패의 전개 양상에 관한 고찰

서희진(Seo, Hee Jin) 한국스포츠사회학회 2019 한국스포츠사회학회지 Vol.32 No.3

이 글의 목적은 최근 우리 사회의 다양한 변화와 맞물려 발현되고 있는 체육계의 불공정을 넘어선 구조적 문제를 부정부패의 관점에서 개괄하는데 있다. 스포츠에서의 부정부패를 이해하기 위해 먼저 투명하고 공정한 사회의 필수요건인 부정부패의 일반적 개념과 유형을 고찰하였으며, 부정부패가 국민의 생명과 국가의 근간을 흔들 수 있다는 영향력을 확인하였다. 스포츠에서의 부정부패는 민간부패로서 뿐만 아니라 스포츠경기의 당사자, 조직의 이해관계자 등 스포츠 환경을 둘러싼 모든 차원에서 발생할 수 있음을 개괄하였다. 스포츠 부정부패는 탈아마추어화, 의학화, 정치화, 상업화 등의 경향 속에서 더욱 다변화될 것이고, 일반화 과정을 통해 전이와 재생산의 메커니즘을 갖게 된다는 점을 제시하였다. 결국 이러한 문제를 해결하는 방법은 좋은 스포츠 거버넌스를 구축함으로써 부정부패를 방지하고 지속가능한 스포츠생태계를 구축하는 노력을 기울이는 것이며, 이를 위해서는 스포츠 세계의 구조와 행위의 상호작용에 대한 통찰이 요청된다. The purpose of this article is to outline structural problems that go beyond the unfairness of the sport world, which has recently emerged in line with various changes in our society, from the perspective of corruption. In order to understand corruption in sport, I first considered the general concept and type of corruption, an essential requirement of a transparent and fair society, and confirmed the influence that corruption could shake the life of the people and the foundation of the nation. It outlined that corruption in sport could occur not only as a civil corruption but also at all levels surrounding the sport environment, such as the parties involved in sport competitions and stakeholders in organizations. It suggested that sport corruption would be further diversified amid trends in de-amateurization, medicalization, politicization and commercialization, and that through the generalization process it would have a mechanism of transference and reproduction. In the end, the way to solve these problems is to make efforts to prevent corruption and build a sustainable sport ecosystem by building good sport governance, which requires insight into the structure and interaction of the sport world.
