Keywords: Technology Innovation Capability; TIC evaluation factors; DEMATEL method; Cause and effect relationship.
Abstract
This study analyzes the technology innovation capabilities (TICs) evaluation factors of enterprises by applying the Decision Making Trial and Evaluation Laboratory (DEMATEL) method. Based on the literature reviews, six main perspectives and sixteen criteria were extracted and then validated by six experts. A questionnaire was constructed and answered by eleven experts. Then the DEMATEL method was applied to analyze the importance of criteria and the casual relations among the criteria were constructed. The result showed that the innovation management capability perspective was the most important perspective and influenced the remaining perspectives. This work also presents the significant criteria for each perspective.

Keywords: Paclobutrazol; 2,4-dichlorophenoxy acetic acid (2,4-D); Benzyl adenine (BA), Somatic embryogenesis
Abstract
The nodal explants of Curcuma var. Chattip could develop callus after in vitro culturing and transplanting within 4 weeks in MS medium supplemented with 1.0 mg/l 2,4-D, although this optimal if the media was further supplemented with 5.0 mg/l BA, obtaining the highest number of new shoots in 6 weeks. MS medium supplemented with 0.01 mg/l paclobutrazol and 15% (v/v) coconut water was found suitable for regenerating the highest number of new shoots (7.25 shoots). The number of leaves per plantlet, length of leaves, and length of petrioles were significantly reduced (p≤ 0.05) when increased concentrations of paclobutrazol and especially paclobutrazol with 15 % (v/v) coconut water. However further experimentation is required to evaluate the dose-response and the interaction between coconut water and paclobutrazol. In contrast, no significant difference in leaf width in all treatments.

Keywords: Large-scale Feed-mix Problem; Bender’s Decomposition; Two-stage Stochastic Programming
Abstract
The feed-mix problem is primarily transformed into a mixing situation applying a mathematic formulation with uncertainties. These uncertainties generate the numerous expansions of alternative constraint equations. The given problem has been formulated as mathematic models which correspond to a large-scale Stochastic Programming that cannot be solved by the most popular ordinary calculation method, Simplex Method: LINPROG. This research aims to investigate effective methodology to reveal the optimal solution. The authors have examined the method of Bender’s decomposition: BENDER and developed both methods into MATLAB® program and calculated comparatively. The results revealed that the nearest optimal solutions can be determined by means of a Two-stage Stochastic Programing incorporated with Bender’s decomposition at the most intensive number of uncertainties and take less calculation time than by LINPROG.

Keywords: Banking; GIS; Loan appraisal; Information technology; Mortgage.
Abstract
Due to liberalization within the financial market, there has been increased cash flow in banks. This has resulted in increased competition among banks to secure and increase their customer base, in an effort to remain profitable. Banks are foregoing the multitude of checks that used to be conducted before granting any mortgage facility to customers, in an effort to remain competitive. This has led to a drastic increase in the number of credit card and loan defaulters, leading to increased operation costs and reduction in profit margins. This research proposes an integrated GIS approach enabling banks locate defaulting real estate properties used as collateral. Using data provided by Kenya Commercial Bank (KCB) for a locality in Kenya, a geodatabase was developed and a custom application developed for the bank loan appraiser to use. This application retrieves property information about a client based on his/her bank account information. Based on a series of spatially driven queries embedded in the solution, the appraiser can prepare a detailed appraisal for the client in a very short time, thereby satisfying the client, while not prejudicing the banks position.

Keywords: DFT; Hetero–Diels–Alder reaction; Nitrosoalkene; ONIOM; SWCNT; Thionitrosoalkene.
Abstract
Two–layered ONIOM method at the ONIOM(B3LYP/6–31G(d,p):AM1) theoretical level was applied to investigate the hetero Diels-Alder reaction functionalization of various nitrosoalkenes (NAs) and thionitrosoalkenes (TNAs) onto side–wall (5,5) armchair SWCNT. The results indicated that SWCNT can be functionalized with NAs and TNAs. The energy barriers of TNAs funtionalized SWCNT were lower than those of NAs. This implied that TNAs are easier to react with SWCNT than those of NAs. In addition, electronic properties and density of states of SWCNT were modified by the Diels-Alder functionalizations of NAs and TNAs.

Keywords: Phenomenology; Local wisdom; Traditional architecture; Lamban tuha, Earthquake resistant structures.
Abstract
Local wisdom of traditional architecture is towards extinction along with the existence an increasingly neglected traditional house, including the one who understands it reduced drastically. Lamban Tuha in South Sumatra has demonstrated the ability to adapt to its environment and able to withstand natural catastrophes. The study used phenomenological method to reveal information from the first person who is considered experts on the local wisdom of Lamban Tuha. This study shows the construction of kalindang provide an excellence effect of providing high flexibility in case of earthquakes. The separation structure between lower, middle and upper parts is done to give building more flexible. Local wisdom is reflections of valuable experience which can be utilized as the concept of a sustainable housing development in the context of anticipate natural disasters. The existence of Lamban Tuha is an interesting experience that can be used as thoughts on designing earthquake resistant buildings.
