우리나라는 항만의 기능 다각화 및 부가가치 창출을 목표로 국내 주요 무역항에 항만배후단지를 단계적으로 개발해왔다. 그러나 이러한 목표를 달성하기 위한 배후단지 입주업체 선정기준에 관한 연구는 아직 부족한 실정이다. 본 연구는 부산항 신항 배후단지를 대상으로 입주업체 특성별 생산성을 비교분석하여 입주업체 선정기준 마련에 기여하고자 하였다. 분석을 위해 67개 업체들의 최근 3년(2017-2019)간 운영실적 자료를 수집하여 단일요소생산성을 측정하였다. 그 결과, 물류업은 물동량, 제조업은 매출액 측면의 생산성에 강점이 있는 것으로 나타났다. 또한, 상대적으로 개장시기가 빨랐던 북컨테이너 배후단지가 웅동 배후단지에 비해 전반적인 생산성이 높았다. 마지막으로 외국인과 시설·설비 투자규모에 따른 생산성의 경우 전반적으로 투자규모가 평균 미만인 업체들이 평균 이상인 업체들보다 생산성이 높은 것으로 분석되어 부정적인 상관관계를 보였다. 따라서 항만배후단지의 생산성 및 경쟁력을 강화하기 위해서는 입주업체들의 고용 및 화물 창출 능력을 제고할 수 있는 제도적·법률적 보완과 신규 입주업체 선정기준의 재확립이 필요하다고 판단된다. Korea has gradually been developing port distriparks in major domestic trade ports to diversify their function and create added-value. New tenant companies are needed to help achieve these goals, but no research has been done on selection criteria. To provide such criteria, this study conducted a comparative analysis of the productivity of tenant companies in Busan New Port Distripark based on their characteristics. SFP (single-factor productivity) was measured using the operational data of 67 companies in the distripark over the past - three years (2017-2019). The results indicate that the logistics business and the manufacturing business have strengths in cargo volume productivity and in sales productivity respectively. Also, Northern distripark, a relatively older facility, was found to be more productive than Ung-dong distripark. Finally, the effect of investment—both foreign and in FAC/EQ (facility and equipment)—on productivity showed an inverse relationship with productivity, with the companies with under-average investments being more productive than those whose investments were above average. Therefore, to enhance the productivity and competitiveness of port distriparks, tenant companies must be subject to supplemented system and law for increasing employment and cargo volume, and reestablished selection criteria.

The participation of active physical activity in children and adolescents is important to acquire the habit of lifelong participation in physical activity and sports in adults. In this sense, the efforts to collaborate between school physical education and community sports is important to activate physical activity for children and adolescents and to create ample opportunities to experience various physical activity. Successful collaboration between school PE and community sports can be attained only by political support from education related administrative organization and by the strong commitment of implementation of the program from administrative organization. Also, an collaboration model and detailed manual to guide to implement the model should be developed and provide to related field. This study was conducted to develope the collaboration model to activate physical activity for children and adolescents. The article discussed basic framework, procedure, and strategies for collaboration between school PE and community sports. The basic framework were discussed in detail such as area of the need of collaboration, the place to start, the objectivity of collaboration, an organization involved to collaborate, and the strategies for implication. The procedure were dealt with the detail process of implementation plan to city hall, community center, physical education association, club activity for community people and university students. Finally, full implementation of the strategies recommended in this article.

<P> Recent increases in the number of irregularly shaped tall buildings have created a need for more applicable formwork methods and automated support for formwork layout planning, which has mainly depended on heuristic approaches based on the intuitive judgment of experienced engineers. This study proposes a new table formwork method integrated with a systematic layout planning approach for tall building construction. Adjustable subunits of the formwork cope with diverse building shapes and the software-based mathematical model helps practitioners make useful layouts for the method with minimal time and effort. In a case study, the proposed layout planning model offered lower costs and improved work efficiency in less time than the heuristic approach. Supported by the planning model, our advanced formwork method showed a 15.5% increase in covered area of irregularly shaped building floors and a 23.9% decrease in material costs compared with existing table formwork methods. </P>

Porcine epidemic diarrhea virus (PEDV) is the causative agent of porcine epidemic diarrhea (PED) and causes a considerable economic loss in swine industry. In this study, the virucidal efficacy of the disinfectant composed to n-alkyl-dimethyl-benzyl-ammonium chloride (n-ADBAC) was investigated against PEDV. A virucidal efficacy was determined with the viability of PEDV contacted with the disinfectant in Vero cells. The disinfectant and PEDV were reacted on the hard water (HW) or organic matter suspension (OM) condition. On HW condition, PEDV was inactivated with 50 fold dilutions of the disinfectant. When the antiviral effect on OM condition was evaluated, the antiviral activity of the disinfectant showed on 10 fold dilutions against PEDV. As the disinfectant possesses the virucidal efficacy against PEDV, the disinfectant solution can be used to limit the spread of animal viral diseases.

Endoscopic biilary drainage (EBD) for malignant obstructive jaundice is performed mostly with EST. But EST carries early complications such as bleeding, perforation and pancreatitis. We evaluated safety and usefulness of EBD using endoscopic papillary balloon dilation (EPBD) without endoscopic sphincterotomy (EST). Fifteen patients were treated from Sep. 1998 to Feb. 1999 in Pusan National University Hospital due to malignant obstructive jaundice. EBD was performed using EPBD. They were investigated to estimate the usefulness and early complications of EBD using EPBD. Effective drainage was achieved in 13 patients (87%). Procedure related complications developed in two patients; acute pancreatitis in two(minimal or mild, 13%), hemorrhage in three (clinically insignificant bleeding) EBD using EPBD is a safe and effective treatment method for malignant obstructive jaundice. However, prospective study is thought to be need in large patients group especially as to stent diameter and papilla size.
