This study aims to explore the relationships between strategic planning, strategic maneuverability, and firm performance in the current dynamic business environment. It employs a quantitative research method and reports on a survey, using a questionnaire, of service companies in Indonesia's oil and gas industry. Of the 337 companies selected by simple random sampling from a vendor database, responses were received from 70 companies. The analysis was performed using Partial Least Square Structural Equation Modeling and SmartPLS software. The analysis consisted of descriptive statistics, evaluation of the measurement model, evaluation of the structural model, and hypotheses testing. The results show that both strategic planning and strategic maneuverability have a positive relationship with firm performance. In addition, there is a positive relationship between strategic planning and firm performance through the mediating role of strategic maneuverability. The findings suggest that the organizational agility, organizational flexibility, and organizational responsiveness that constitute strategic maneuverability have a positive direct and indirect effect on firm performance, namely financial performance, customer performance, internal process performance, and learning and growth. This study contributes to the strategic management literature and the theory of maneuvers by providing empirical evidence on the relationship between strategic planning, strategic maneuverability, and firm performance.

Recently, new concept and paradigm of 'Environmentally-Friendliness' is taking a growing interest in environmental planning and design. This study is to establish the evaluation model for environmentally-friendliness of 'Tourism Farms' in rural areas by LISREL structural equation model. A questionnaire survey was conducted for deputy manager group and expert group. As the Result of LISREL structural equation model, the environmentally-friendliness of tourism farms is composed of three categories. First, conservation of global environment (Low Impact), second, friendliness to surrounding nature(High Contact), and third, environmental health and amenities (Health & Amenity). Five indicators, such as (1)saving of energy and water resource, (2)reduction and reuse of garbage, (3)natural purification of sewage disposal, (4)utilization of natural energy, (5)campaign and education programs of environmentally-friendliness, were affecting the first category, i.e., conservation of global environment(Low Impact). Friendliness to surrounding nature (High Contact) is affected by 3 indicators, (1)contact to nature and diverse green areas, (2)water intimate & contact areas, (3)natural ecology observation by biotope. Finally, the dimension of environmental health and amenity is affected by 3 indicators, (1)nature affinity by farming experience, (2)environmental-friendliness of soil & crops by organic farming, (3) campaign and education programs of environmentally-friendliness. Total coefficient of determination of the structural equation model by LISREL was 0.897, which showed high explanatory power.

This paper introduces three distinctive means for the use of a 189-meter high damped structure ensuring safety against earthquake: 1. Realization of L-shaped elevational structural planning: The bottom and top of the tower have belt trusses and hat trusses respectively to restrain the bending deformation. Furthermore, large-capacity oil dampers (damping force 6,000 kN) are installed in the middle part of the tower to restrain the higher-mode deformation. 2. Realization of L-shaped planar structural planning: We devised a means of matching the centers of gravity and rigidity by adjusting planar rigidity. Moreover, viscous damping devices are located at the edges of the L-shaped plan, where torsional deformation tends to be amplified. We call this the "Damping Tail" system. 3. Composite foundation to equalize deformations under different loading conditions: We studied the vertical and horizontal deformations using sway-rocking and 3D FEM models including the ground, and applied multi-stage diameter-enlarged piles to the tower and a mat foundation to the podium to keep the foundations from torsional deformations and ensure structural safety.

In this study, the structural stability of the tank room of an aircraft rescue fire engine is to be studied. The tank room of the aircraft rescue fire engine is filled with fire extinguishing water and chemicals. Fire extinguishing water and chemical are filled to a capacity of about 12.5 tons and are subjected to high stress. The tank room is made of PP material with low yield stress. Structural analysis of the tank room is performed and structural weakness is analyzed. In addition, if a structural problem occurs as a result of structural analysis, an analysis simulation result is presented to derive an improved design and to show the validity of the structural stability of the tank room.

본 논문에서는 국내의 초고층 주상복합건축물들에 대하여 층수와 높이 등의 규모 및 구조형식과 횡력저항 시스템의 유형 및 사용 재료의 강도와 층별 콘크리트 강도의 조닝 등에 대하여 조사 분석하여, 이를 토대로 초고층 주상복합 건축물의 구조 계획 유형을 분석하였다. 조사한 결과, 국내 초창기 초고층 주상복합 건축물의 구조시스템은 도곡동 타워팰리스와 같이 철골철근콘크리트구조(SRC)로 건설된 사례가 많았으나, 2005년 이후에는 대부분이 철근콘크리트(RC)구조로 건설되었다. 구조체에서 코어부분을 전단벽으로 배치하여 횡력저항 시스템으로 활용하고 있고, 콘크리트의 강도는 층수에 따라 고층부, 중간부, 저층부로 나누어 강도를 조닝하여 적용하고 있었다. 사례조사를 토대로 국내에 주상복합건축물의 대표적인 유형으로 건설되고 있는 40층 및 60층 규모의 건축물에 대한 구조계획 기초자료를 제시하였다.

Civil engineering infrastructure is aging and requires cost-effective maintenance strategies to enable infrastructure systems operate reliably and sustainably. This paper presents an approach for determining risk-cost balanced repair strategy of corrosion damaged reinforced concrete structures with consideration of uncertainty in structural resistance deterioration. On the basis of analytical models of cover concrete cracking evolution and bond strength degradation due to reinforcement corrosion, the effect of reinforcement corrosion on residual load carrying capacity of corroded reinforced concrete structures is investigated. A stochastic deterioration model based on gamma process is adopted to evaluate the probability of failure of structural bearing capacity over the lifetime. Optimal repair planning and maintenance strategies during the service life are determined by balancing the cost for maintenance and the risk of structural failure. The method proposed in this study is then demonstrated by numerical investigations for a concrete structure subjected to reinforcement corrosion. The obtained results show that the proposed method can provide a risk cost optimised repair schedule during the service life of corroded concrete structures.

기술기획 과정은 특정 절차에 따른 일상적 반복 업무가 아니라 절차로 규정되지 않는 복잡한 연구적 과정이다. 기술기획을 위해 모인 전문가 집단은 시장수요 및 창출에 적합한 새로운 기술과제를 탐색하기 위해 구성된다. 전문가들은 각자가 지니고 있는 지식기반을 바탕으로 미래 기술발전 방향을 연구하는 혁신활동을 진행한다. 본 연구는 이와 같은 기술기획 과정을 조직학습의 관점으로 조명하는 논의를 전개하였다. 이를 위해 탐색적 가설을 도출하고 실증적 검증을 위해 2012년도 국가연구개발사업의 에너지R&D를 하나의 혁신 체제의 장소로 삼고, 참여한 경제성 전문가와 기술 전문가 간의 기획프로세스 내 관계에서 혁신이 창출되는 과정을 실증하였다. R&D 전문가와 경제성분석 전문가간의 상호작용과 지식창출간에 있어 변수들 간의 구조적 관계를 동시에 추정 할 수 있는 구조방정식 모형(Structural Equation Modeling : SEM)을 적용하였다. 연구결과는 혁신 주체 간 상호작용의 수준이 깊어질수록 지식창출이 높아지고 혁신을 촉진하게 됨을 알 수 있다. 이러한 지식창출은 단순한 만남 등 교류보다 협의수준을 높이고 또한 조직학습 효과를 강화할 때 지식창출에 혁신을 가져왔다. 본 연구는 국가연구개발사업의 과제기획을 수행하는 전문가 그룹 운영에 있어 지식창출 촉진을 위해 전문가를 다양화하고 상호발표회, 현장방문, 교차점검 등 내부적 자원과 외부적 자원의 의사소통 방식을 관리하는 실무적 가이드라인을 제시한다.
