본 연구에서는 특정 비디오에서 추출된 비디오 클립이 어떤 비디오에서 추출된 것인지 탐색하는 알고리즘을 제안한다. 국내 이스포츠 리그 중 하나인 LCK의 경기 영상과 하이라이트 영상을 수집하여 알고리즘의 성능을 테스트하였다. 본 연구에서 제안한 알고리즘은 하이라이트 비디오 추출 모델개발에 필요한 비디오-하이라이트 클립 데이터셋을 구축하는 데 도움이 될 것이라 기대한다.

This paper describe the Lateral Navigation algorithm design and verification that implementation on Mission Computer's OFP for Korean Utility Helicopter(KUH) instead of Auto Flight Control System(AFCS) Vehicle Management System. The LNAV function transmits Roll command into the AFCS System. The Roll command value will be calculated by control algorithms in MC. The Operational Flight Program(OFP) shall use for its calculations different measurements of the aircraft's attitude and place. Using these inputs, the OFP will translate a navigational demand(for example-to perform the selected flight plan) into Roll commands to the autopilot. By conducting integration test using SIL and ground test, flight test, it is confirmed that the introduced algorithm meets the requirements of the Mission Equipment Package(MEP) system. LNAV function is verified through the System Integration Laboratory(SIL) test, ground and flight test.

The purpose of this study is to establish evaluation model that can explain marginal effects of baseball players of Korean Baseball Organization (KBO) on their team winnings in terms of productivity. We proposed econometric model with using variables that are provided from official homepage of KBO to overcome the complexity of mainly used productivity index: wins above replacement (WAR). Also, compare to the previous studies such as Scully(1974) or Krautmann(1999) that using limited indices of baseball stats, this study included 61 indices that are provided from official homepage of KBO. We estimated regression based WAR(RBWAR) by conducting panel regression with each team's statistics data of 2002 to 2014. As a results, RBWAR shows 0.869 correlation coefficient for batters and 0.882 for pitchers with WAR in 2014 that can be concluded that two indices shows similar results. From the results of estimation, we analyze the relationship between productivity and actual contract of free agent players in 2015 and it showed that teams have contracted reasonably.

The purpose of this study was to analyze records of Korean pro-basketball using general linear model (two-way ANOVA and hierarchical multiple regression analysis). Korea Basketball League (KBL) informed the records (2014-2015 season) of this study. The eight variables (TA, 2PA, 3PA, 2P, 3P, Ast, TFB, CH) were selected in content validity. SPSS program was used to analyze general linear model. All alpha level was set at 0.05. Major results were as follow. 3PA had significant interaction effect between victory & defeat variable and home & away variable. Victory teams showed that 3PA was higher in home games than away games, and defeat teams was the other. 2PA, AS, TFB, and CH were selected significant variables affecting victory and defeat. In result of hierarchical regression, Ast had significant moderation effect between 3PA and TS. TFB also had significant moderation effect between AS between 2P. The other construct (Ast between 2PA and TS; TFB between AS between 3P) had no significant moderation effect. In the effect of 2PA, 3PA and Ast to TS, CH also had no significant moderation effect.

This study has the following two focuses to analyze the changes in national-level locational pattern of the U.S. professional sports franchises during 1950-2001. The first is to empirically clarify spatial orientation in the changing locational pattern of sports franchises. The second is to identify compared characteristics of the relocation cases reflecting the orientation to other cases, for the variables indicative of franchises' and leagues' pursuits of their relocation-related interests ultimately affecting franchises' relocations, by employing a legit model. As a result of the analyses, sports franchises and leagues, respectively have shown spatial orientation toward relocating to and toward locating new franchises in southern and western areas, responding to the changes in U.S. urbanization pattern. And, relocation cases reflecting the orientation have displayed a feature of the higher annual population growth rate in destination urban area than in origin area, in comparison to other cases.

In this study, the effect of spray-drying conditions and surfactant addition on the spray-drying yield, morphological characterization, size distribution and re-dispersity in water of spray-dried lignocellulose nanofibril (LCNF) were investigated. The freeze-dried LCNF after solvent exchange had linear fiber morphology with a diameter of 70-300 nm, and the spray-dried LCNF showed rod-like particle morphology. The spray-drying yield and particle size of spary-dried LCNF at $140^{\circ}C$ was highest and smallest, respectively. As LCNF concentration and blowing rate decreased and increased, respectively, the spray-drying yield and particle size were increased. The highest spray-drying yield was found at distearyl dimethyl ammonium chloride (DDAC) addition of 10 phr at $140^{\circ}C$. As the particle size decreased and the DDAC content increased, filtration time of spray-dried LCNF in water was decreased and increased, respectively.

리그노셀룰로오스 바이오매스를 원료로 하여 발효당을 생산하고자 할 때 최종적인 당수율은 적용하는 전처리 기술의 종류와 전처리 조건에 따라 크게 달라질 수 있다는 사실은 널리 알려져 있다. 또한 전처리물의 효소당화에서 셀룰로오스의 당전환율은 효소의 종류와 사용량에 의존적이므로 부족한 전처리 효과를 일부 보완하기도 한다. 본 연구에서는 바이오매스의 효소당화에 흔히 사용되고 있는 특정효소와 최근 공급되기 시작한 새로운 효소를 시료로 하여 해바라기 줄기의 열수전처리에 이은 효소당화에서 효소의 종류가 최종 당수율, 효소당화 시간 및 전처리효과에 미치는 영향을 측정하였다. 해바라기 줄기 분말을 $180^{\circ}C$에서 30분 동안 열수전처리하였을 때 헤미셀룰로오스의 수율이 최대가 되었으나 이 조건에서는 후속 효소당화에 의한 포도당 수율이 높지 않았다. Celluclast 1.5L 혹은 Celluclast conc BG는 전처리 물의 당화속도가 상대적으로 빠른 편이었고, 이 효소에 의한 당수율은 해바라기 줄기 셀룰로오스 함량의 80% 내외였으며, 바이오매스 1g당 효소첨가량이 3ml까지 증가함에 따라 당수율도 꾸준히 증가하는 경향을 보였다. 반면에 노보자임 스코리아로부터 분양받은 효소로서 NS22074와 NS50010의 혼합물은 Celluclast보다 약 10% 더 높은 당수율을 보여주었으나 당화는 상대적으로 느리게 진행되어 72시간 이상이 소요되었다. Endoxylanase 혹은 hemicellulase 등 다른 효소를 NS22074와 NS50010의 혼합물에 가하여도 당수율의 증대 효과는 미미하거나 거의 없었다. 시험에 사용한 효소제제에는 포도당, 소르비톨 등 여러 가지 당들이 보존제 혹은 안정화제로 함유되어 있는 것으로 나타나서 사용에 주의할 필요가 이었다.

Consumer's buying loyalty for goods can be changed by exposure to new stimulus, so different with others and esthetical packaging design is necessary for drawing the eyes of consumer at this time. In this study, we made up a questionnaire and analyzed thirties who is judged as a substantial consumer for recognition of newly launched seasoning packaging design. They answered there is no specific character comparatively in existing seasoning packaging design and gave a high appraisal on symbolism of calligraphy logotype which is produced by attributes but got a low appraisal on readability. And they appraised Cheong-jeong-won Maat-seon-saeng higher than Da-si-da San-deul-e on safety, quality preservation, and exhibitivity and chose safety and preservation among those as essential element inducing to buy.
